The use of strong colours in cast glass died out during this period, with colourless or 'aqua' glasses dominating the last class of cast vessels to be produced in quantity, as mould and free-blowing took over during the 1st century AD. From around 70 AD colourless glass becomes the predominant material for fine wares, and the cheaper glasses move towards pale shades of blue, green, and yellow. Debate continues whether this change in fashion indicates a change in attitude that placed glass as individual material of merit no longer required to imitate precious stones, ceramics, or metal, or whether the shift to colourless glass indicated an attempt to mimic highly prized rock crystal. Pliny's Natural History states that "the most highly valued glass is colourless and transparent, as closely as possible resembling rock crystal" (36, 192), which is thought to support this last position, as is evidence for the persistence of casting as a production technique, which produced the thickly walled vessels necessary to take the pressure of extensive cutting and polishing associated with crystal working.

While the inner epidermis may remain a single layer, it may also divide to produce two to three layers and accumulates starch, and is referred to as the colourless layer. By contrast the outer epidermis becomes tanniferous. The inner integument may consist of eight to fifteen layers.
He wrote of the alkaloid's "colourless transparent prisms" and said that, "Its solutions have an alkaline reaction, a bitter taste, promote the flow of saliva and leave a peculiar numbness, followed by a sense of cold when applied to the tongue." Niemann named the alkaloid "cocaine" — as with other alkaloids its name carried the "-ine" suffix.
Liquid iodine trichloride conducts electricity, possibly indicating dissociation to and ions.Greenwood and Earnshaw, pp. 828–31 Iodine pentafluoride (IF5), a colourless, volatile liquid, is the most thermodynamically stable iodine fluoride, and can be made by reacting iodine with fluorine gas at room temperature. It is a fluorinating agent, but is mild enough to store in glass apparatus.
The reports on larvae are somewhat divergent, depending on the species and the condition of the larvae (fresh versus alcohol-preserved): The fully-grown caterpillar of Niphopyralis myrmecophila (according to material preserved in alcohol) is approximately 14 mm in length, 4.4 mm thick at its largest diameter, and completely colourless, with the spiracles visible as fine, shiny colourless dots. The larval body is naked, hardly flattened, markedly tapered anteriorly and posteriorly, with all segments bulging out almost in a physogastric way. The head is small and prognathous. The thoracal legs are well developed, the prolegs are strongly reduced, and only at high magnification the single circle of crochets and the small papilla are visible; the anal prolegs are completely reduced, but this may be due to the investigated larvae being in the process of pupation.
Bases may be bayonet-type with one or two contacts, plastic or glass wedge, or dual wire loops or ferrules used on tubular "festoon" lamps. Screw-base lamps are never used in automobile applications due to their loosening under vibration. Signal lamps with internal or external coloured lenses use colourless bulbs; conversely, lamps with colourless lenses may use red or amber bulbs to provide light of the required colours for the various functions. Typically, bulbs of 21 to 27 watts producing 280 to 570 lumens (22 to 45 mean spherical candlepower) are used for stop, turn, reversing and rear fog lamps, while bulbs of 4 to 10 W, producing 40 to 130 lm (3 to 10 mscp) are used for tail lamps, parking lamps, side marker lamps and side turn signal repeaters.

Pests and diseases are a serious problem for this grape variety, since it has little resistance to either. The grape forms compact, cylindrical bunches of spherical, deep blue-black fruit with a colourless pulp. The leaves are large with five overlapping lobes.
Noctilucent clouds are generally colourless or pale blue, although occasionally other colours including red and green occur.Gadsden (1995), p.13. The characteristic blue colour comes from absorption by ozone in the path of the sunlight illuminating the noctilucent cloud. They can appear as featureless bands, but frequently show distinctive patterns such as streaks, wave-like undulations, and whirls.Gadsden (1995), pp.8–10.
It is soluble in a wide range of organic solvents. It is also moderately soluble in water, with which it reacts reversibly to form osmic acid (see below). Pure osmium(VIII) oxide is probably colourless and it has been suggested that its yellow hue is due to osmium dioxide (OsO2) impurities. The osmium tetroxide molecule is tetrahedral and therefore non-polar.

Metcalf "Insect Control" in Ullmann's Encyclopedia of Industrial Chemistry Wiley-VCH, Wienheim, 2002.
He remarked that "the Kaiser is exposed as a master intriguer and Mephistophelian plotter for German domination of the world. The former Tsar is revealed as a capricious weakling, a characterless, colourless nonentity." The two, Bernstein wrote, "both talked for peace and plotted against it." In 1915, Bernstein published a book, La Rekta Gibulo, in the so-called universal language Esperanto.
Melanin colours the skin of many species, but in fish the epidermis is often relatively colourless. Instead, the colour of the skin is largely due to chromatophores in the dermis, which, in addition to melanin, may contain guanine or carotenoid pigments. Many species, such as flounders, change the colour of their skin by adjusting the relative size of their chromatophores.

The gas is colourless and highly explosive. If there is sufficient in the air it reduces the amount of oxygen and causes suffocation. Methane is lighter than air and it builds up under the roof of the mine. In a working pit the ventilation fans prevent this from happening, but when the fans stop the methane build up in the abandoned workings.
The primary method of including colour in stained glass is to use glass, originally colourless, that has been given colouring by mixing with metal oxides in its melted state (in a crucible or "pot"), producing glass sheets that are coloured all the way through; these are known as "pot metal" glass."Facts about Glass – Creating Coloured Glass; Pot-metal glass", Boppard Conservation Project – Glasgow Museums A second method, sometimes used in some areas of windows, is flashed glass, a thin coating of coloured glass fused to colourless glass (or coloured glass, to produce a different colour). In medieval glass flashing was especially used for reds, as glass made with gold compounds was very expensive and tended to be too deep in colour to use at full thickness.Investigations in Medieval Stained Glass: Materials, Methods, and Expressions, xvii, eds.

Asci are arranged in two rows with thin, smooth walls; they are initially colourless but become red-brown with age. The asci are stored in the hymenial cavity which is often slightly depressed with a pink or orange tint.
The densest parts of the negative require more exposure. The exposed print is then developed gradually in a succession of trays of still water (approximately ten-minute intervals) at room temperature until the bath water is clear. The gum is soft and easily removed at this stage. The negative is then carefully dried when the negative image will be visible as raised areas of clear colourless gum.
Thionyl chloride is an inorganic compound with the chemical formula . It is a moderately volatile colourless liquid with an unpleasant acrid odour. Thionyl chloride is primarily used as a chlorinating reagent, with approximately per year being produced during the early 1990s. It is toxic, reacts with water, and is also listed under the Chemical Weapons Convention as it may be used for the production of chemical weapons.
Thionyl chloride has a long shelf life, however "aged" samples develop a yellow hue, possibly due to the formation of disulfur dichloride. It slowly decomposes to S2Cl2, SO2 and Cl2 at just above the boiling point. Thionyl chloride is susceptible to photolysis, which primarily proceeds via a radical mechanism. Samples showing signs of ageing can be purified by distillation under reduced pressure, to give a colourless liquid.
Atomic carbon, systematically named carbon and λ0-methane, also called monocarbon, is colourless gaseous inorganic chemical with the chemical formula C (also written [C]). It is kinetically unstable at ambient temperature and pressure, being removed through autopolymerisation. Atomic carbon is the simplest form of carbon, and is also the progenitor of carbon clusters. In addition, it may be considered to be the graphite monomer.
Although it is not a nitrogen hydride, hydroxylamine (NH2OH) is similar in properties and structure to ammonia and hydrazine as well. Hydrazine is a fuming, colourless liquid that smells similarly to ammonia. Its physical properties are very similar to those of water (melting point 2.0 °C, boiling point 113.5 °C, density 1.00 g/cm3). Despite it being an endothermic compound, it is kinetically stable.
Greenwood and Earnshaw, pp. 412–16 Given the great reactivity of atomic nitrogen, elemental nitrogen usually occurs as molecular N2, dinitrogen. This molecule is a colourless, odourless, and tasteless diamagnetic gas at standard conditions: it melts at −210 °C and boils at −196 °C. Dinitrogen is mostly unreactive at room temperature, but it will nevertheless react with lithium metal and some transition metal complexes.
Chlorodiphenylphosphine is an organophosphorus compound with the formula (C6H5)2PCl, abbreviated Ph2PCl. It is a colourless oily liquid with a pungent odor that is often described as being garlic-like and detectable even in the ppb range. It is useful reagent for introducing the Ph2P group into molecules, which includes many ligands.Quin, L. D. A Guide to Organophosphorus Chemistry; Wiley IEEE: New York, 2000; pp 44-69.
Fluorine condenses to a pale yellow liquid at −188.11 °C and freezes into a colourless solid at −219.67 °C. The solid form (density 1.7 g/cm−3) has a cubic crystalline structure and is soft and easily crushed. Fluorine is an insulator in all of its forms. It has a high ionisation energy (1681 kJ/mol), high electron affinity (328 kJ/mol), and high electronegativity (3.98).
H and N. Both are relatively unreactive colourless diatomic gases, with comparably high ionization energies (1312.0 and 1402.3 kJ/mol), each having half-valence subshells, 1s and 2p respectively. Like the reactive azide N3− anion, inter- electron repulsions in the H− hydride anion (with its single nuclear charge) make ionic hydrides highly reactive. Unusually for nonmetals, the two elements are known in cationic forms.
Northupite is an uncommon evaporite mineral, with the chemical formula Na3Mg(CO3)2Cl. It occurs as colourless to dark grey or brown octahedral crystals and as globular masses. In synthetic material it forms a series with tychite (Na6Mg2(CO3)4SO4). It was discovered in 1895 at Searles Lake, San Bernardino County, California by C. H. Northup (born 1861) from San Jose, California, for whom Northupite is named.
1,3-Dimethyl-2-imidazolidinone (DMI) is a cyclic urea used as a high-boiling polar aprotic solvent.Leahy, Ellen M. "1,3-Dimethyl-2-imidazolidinone" e-EROS Encyclopedia of Reagents for Organic Synthesis (2001), It is colourless, highly polar solvent has high thermal and chemical stability. It is a homolog of the related solvent DMPU. It can be prepared from 1,2-dimethylethylenediamine by reaction with phosgene.
The holdfast of C. tomentosum is saucer-shaped and has closely woven strands giving it a uniform appearance. The thallus or frond has a dichotomous, much branched structure with thin branches, each with a circular cross section. It grows to 30 cm (12 in) in length and is spongy, with the texture of felt. It is covered with colourless hairs which are visible when it is submerged.
Phenylarsonic acid is the chemical compound with the formula C6H5AsO(OH)2, commonly abbreviated PhAsO3H2. This colourless solid is an organic derivative of arsenic acid, AsO(OH)3, where one OH group has been replaced by a phenyl group. The compound is a buffering agent and a precursor to other organoarsenic compounds, some of which are used in animal nutrition, e.g. 4-hydroxy-3-nitrobenzenearsonic acid.
Acetic acid , systematically named ethanoic acid , is a colourless liquid organic compound with the chemical formula CH3COOH (also written as CH3CO2H, C2H4O2, or HC2H3O2). When undiluted, it is sometimes called glacial acetic acid. Vinegar is no less than 4% acetic acid by volume, making acetic acid the main component of vinegar apart from water. Acetic acid has a distinctive sour taste and pungent smell.
In the 1983–84 Ahlenfelder was voted best German football referee and awarded the Golden Whistle (German: Goldene Pfeife). In an interview in 2007 Ahlenfelder stated that he missed the attention he received while refereeing. He also stated that modern referees were too colourless and restricted by the rules of the game, exposed to constant surveillance and criticism.Startseite Ex-Schiri Ahlenfelder über Fanta, Fans und Funktionäre reviersport.
Hexachlorocyclopentadiene (HCCPD), also known as C-56, Graphlox, and HRS 1655, is an organochlorine compound with the formula C5Cl6. It is a precursor to pesticides, flame retardants, and dyes. It is a colourless liquid although commercial samples appear lemon-yellow liquid sometimes with a bluish vapour. Many of its derivatives proved to be highly controversial, as studies showed them to be persistent organic pollutants.
Retrieved on 2009-02-24 but gradually declining sales saw the cessation of production in the 1960s. In Switzerland, the ban served only to drive the production of absinthe underground. Clandestine home distillers produced colourless absinthe (la Bleue), which was easier to conceal from the authorities. Many countries never banned absinthe, notably Britain, where it had never been as popular as in continental Europe.
Nitryl fluoride, NO2F, is a colourless gas and strong oxidizing agent, which is used as a fluorinating agentMerck Index, 13th edition (2001), p.1193 and has been proposed as an oxidiser in rocket propellants (though never flown). It is a molecular species, not ionic, consistent with its low boiling point. The structure features planar nitrogen with a short N-F bond length of 135 pm.
They are often stronger than the mass-produced varieties and taste more strongly of apples. Almost colourless, white cider has the same apple juice content as conventional cider but is harder to create because the cider maker has to blend various apples to create a clearer liquid. White ciders tend to be sweeter and more refreshing. They are typically 7–8 % ABV in strength.
White cider is made from pomace, the dry apple pulp left over after juicing, and the final product is almost colourless. Some manufacturers make white cider from imported apple concentrate mixed with glucose or corn syrup. A key market segment exists in the UK for strong mass-produced cider at 7.5% alcohol by volume. Cider with higher than 7.5% alcohol has a higher rate of excise duty.
Structure of HfCl4(thf)2. The compound hydrolyzes, evolving hydrogen chloride: :HfCl4 \+ H2O → HfOCl2 \+ 2 HCl Aged samples thus often are contaminated with oxychlorides, which are also colourless. THF forms a monomeric 2:1 complex: :HfCl4 \+ 2 OC4H8 → HfCl4(OC4H8)2 Because this complex is soluble in organic solvents, it is a useful reagent for preparing other complexes of hafnium. HfCl4 undergoes salt metathesis with Grignard reagents.
The amphithecium (a layer of cells that surrounds the apothecium) has pseudocyphellate papillae, without spots or stains. Asci are elongated, club-shaped (clavate), Lecanora-type, and thickened at the tip. They lack an internal apical beak, and have between 8 and 32 spores. Ascospores of Melanohalea are spherical to ovoid or ellipsoid in shape, thin-walled, colourless, and measure 5.5–20 by 4–12.5 μm.
Microscopically, the fruit bodies are composed of hyphae lacking clamp connections in a gelatinous matrix. The spore-bearing surface is initially covered in a layer of weakly branched hyphidia below which the basidia are formed. The basidia are tremelloid (ellipsoid and vertically septate), giving rise to long, sinuous sterigmata or epibasidia on which the basidiospores are produced. These spores are ellipsoid to oblong, smooth, and colourless.
The amethyst is a brilliant transparent stone of a purple colour and varying in shade from violet purple to rose. There are two kinds of amethysts: the oriental amethyst, a species of sapphire which is very hard (cf. Heb.,hlm), and when colourless is almost indistinguishable from the diamond. The occidental amethyst is of the silex family and different in composition from the oriental stone.
Clavularia crassa forms small colonies of up to about fifty individual polyps growing from a stolon. This grows along the surface of the substrate and it, and the bases of the polyps, are orangish-brown. Each polyp is up to long and wide. The column is slender and creamy-white and the eight long, feathery tentacles are either transparent white, or colourless flecked with white.
Tetrakis(acetonitrile)copper(I) hexafluorophosphate is a salt with the formula [Cu(CH3CN)4]PF6. It is a colourless solid that is used in the synthesis of other copper complexes. The cation [Cu(CH3CN)4]+ is a well-known example of a transition metal nitrile complex.Silvana F. Rach, Fritz E. Kühn "Nitrile Ligated Transition Metal Complexes with Weakly Coordinating Counteranions and Their Catalytic Applications" Chem. Rev.
The animals' upper parts are purplish-grey to blue-black, while the under parts and areas around the eyes and ears can be brownish-pink. Their skin secretes a natural sunscreen substance which is red-coloured. The secretion is sometimes referred to as "blood sweat", but is neither blood nor sweat. This secretion is initially colourless and turns red-orange within minutes, eventually becoming brown.
The only furniture consisted of a hundred little black cuboid moveable stools. For worship, an altar was set up and the faithful surrounded it on three sides. Corpus Christi in Aachen was Schwartz's first parish church and adheres to the same principles, very much reminiscent of the Bauhaus movement of art. Externally it is a plan cube; the interior has white walls and colourless windows, a langbau i.e.
The pulp is colourless and meaty; the hard skin of the round medium-sized berries is intensely and brightly coloured, the smell is fresh, original and fragrant. The taste is pleasantly acidic and tannic. The average bunch is of medium-large size, compact, with an irregular cone shape. The must is normally high in colorants and tannins and is suitable both for aging and for coupage with other varieties.
Ballerus ballerus is one of the more streamlined breams, with a more laterally compressed body, especially towards the tail and an upturned mouth. The eye is small It has small scales and the lateral line consists of 67-75 scales. It is a pale silvery colour with either pale yellowish or colourless fins. They are normally 25–35 cm in length but occasionally can be up to 40 cm.
The upper parts of head and body are greyish-brown flecked with buff; each hair has a grey base and shaft, and a buff or blackish tip. The underparts are whitish-grey, each individual hair having a grey base and shaft and a cream or whitish tip. The tail is colourless and is clad in short white fur. The fore feet have four digits and the hind feet five.
The spores are pip-shaped and covered with tiny spines, amyloid, colourless, and measure 5.8–6.3 by 3.8–4.7 µm. The basidia (spore-producing cells) are club shaped with clamps at their bases, four-spored with sterigmata up to 4.5 µm long, and have dimensions of 22–25 by 5.5–7 µm. The cap tissue consists of generative hyphae, thick-walled skeletal hyphae, and some oleiferous (lipid-containing) hyphae.
The work resumed in the late 1980s and was completed in 1991. The project was modified by a Belgrade-based company, replacing the copper- coloured facade with colourless reflective material, which gives a sky-blue reflection on a clear day (hence the current name). The skyscraper is 120 meters high and has 28 storeys. Prominent former tenants include Peugeot and Sony which had large neon signs on the building.
The other type of ice is called "clear ice", which has a colourless appearance and is formed when ice crystals build up below the frozen surface in cold temperatures. If snow accumulates on the ice it can negatively impact the conditions for skating. Snow depresses the ice surface and slows down the formation of ice crystals beneath the surface. Ice conditions can be classified as very good, good, fair or poor.
Formaldehyde ( , also ) (systematic name methanal) is a naturally occurring organic compound with the formula CH2O (H−CHO). The pure compound is a pungent-smelling colourless gas that polymerises spontaneously into paraformaldehyde (refer to section Forms below), hence it is stored as an aqueous solution (formalin). It is the simplest of the aldehydes (R−CHO). The common name of this substance comes from its similarity and relation to formic acid.
Insoluble in water but soluble in organic liquids (as well as carbon disulfide and trichloroacetic acid), phosphine is a strong reducing agent.Greenwood and Earnshaw, pp. 492–3 Arsine, stibine and bismuthine are highly toxic, thermally unstable, and colourless gases. No appreciable hydrogen bonding is found in phosphine, arsine, stibine or bismuthine, and there is no appreciable tendency to dissociate like ammonia to and (M = P, As, Sb, Bi).
Counterfeit banknote detection pens are used to detect counterfeit Swiss franc, euro and United States banknotes, amongst others. Typically, genuine banknotes are printed on paper based on cotton fibers and do not contain the starches that are reactive with iodine. When the pen is used to mark genuine bills, the mark is yellowish or colourless. Such pens are most effective against counterfeit notes printed on a standard printer or photocopier paper.
The Way It Came is a short story published in 1896 in London by American writer Henry James. The unnamed female narrator recounts her obsession with the mystical coincidence of two friends who seem destined to meet and who apparently do unite in spirit after death. Calling the story's original title "colourless", James renamed it "The Friends of the Friends" in 1909, revising it for inclusion in the New York Edition.
The egg is spherical, colourless and buoyant, 0.5 to 0.6 mm in diameter, and without a large oil globule. Fecundity varied between 16 682 and 166 130. The eggs and larval development of S. sihama has been extensively described separately by Bensam and Kato et al., with the distinguishing feature of the larvae being the pattern of melanophores distributed on the caudal fin base, having these in a vertical line.
1999, Philadelphia: University of Pennsylvania Museum of Archaeology and Anthropology. but those made during the later period usually have a colourless background covered with a translucent coloured layer. Blanks could be produced by fusing two separately cast sheets of glass, or by dipping the base glass into a crucible of molten overlay glass during blowing. The most famous example of a cameo from the early period is the Portland Vase.
Methylethyl ketone oxime is the organic compound with the formula C2H5C(NOH)CH3. This colourless liquid is the oxime derivative of methyl ethyl ketone. MEKO, as it is called in the paint industry, is used to suppress "skinning" of paints: the formation of a skin on paint before it is used. MEKO functions by binding the drying agents, metal salts that catalyze the oxidative crosslinking of drying oils.
Icodextrin is a starch- derived, branched, water-soluble glucose polymer linked by α-(1→4) and less than 10% α-(1→6) glycosidic bonds, making it a type of dextrin. Its weight- average molecular weight is between 13,000 and 19,000 Daltons and its number- average molecular weight between 5,000 and 6,500 Daltons. The substance is a white to off-white solid, and the solution is clear and colourless to pale yellow.
Phenethylamine is a primary amine, the amino-group being attached to a benzene ring through a two-carbon, or ethyl group. It is a colourless liquid at room temperature that has a fishy odor, and is soluble in water, ethanol and ether. Its density is 0.964 g/ml and its boiling point is 195 °C. Upon exposure to air, it combines with carbon dioxide to form a solid carbonate salt.
The conserved Fe3+ is stabilised in the ferric form, whereas M may undergo reduction. Upon treatment with mild reductants, PAPs are converted to their enzymatically active, pink form. Treatment with strong reducing agents dissociates the metallic ions, and renders the enzyme colourless and inactive. PAPs are highly conserved within eukaryotic species, with >80% amino acid homology in mammalian PAPs, and >70% sequence homology in PAPs of plant origin.
Iron oxide deposits give water a reddish hue, as dissolved ferrous oxide becomes oxidized at the surface and is precipitated. Like the hot springs in the nearby city of Bath's Roman built baths, the water is reputed to possess healing qualities. Another spring, known as the White Spring, emerges slightly east of the Chalice Well or Red Spring. The water from this comes from a shallower aquifer and is colourless.
This genus consists of diverse, colourless euglenoids that range in size from 8-75um. Individuals are assigned to this genus if they have characteristic such as an ingestion apparatus, a capacity for flagellar movement and a recurrent flagellum that is not adpressed to the ventral side of the cell.Breglia, Susana A.; Yubuki, Naoji; Leander, Brian S. (2013). “Ultrastructure and Molecular Phylogenetic Position of Heteronema scaphrum: A Eukaryovorous Euglenid with a Cytoproct”.
A hydroid is a type of vascular cell that occurs in certain bryophytes. In some mosses such as members of the Polytrichaceae family, hydroids form the innermost layer of cells in the stem. At maturity they are long, colourless, thin walled cells of small diameter, containing water but no living protoplasm. Collectively, hydroids function as a conducting tissue, known as the hydrome, transporting water and minerals drawn from the soil.
Triethylamine is the chemical compound with the formula N(CH2CH3)3, commonly abbreviated Et3N. It is also abbreviated TEA, yet this abbreviation must be used carefully to avoid confusion with triethanolamine or tetraethylammonium, for which TEA is also a common abbreviation. It is a colourless volatile liquid with a strong fishy odor reminiscent of ammonia. Like diisopropylethylamine (Hünig's base), triethylamine is commonly employed, usually as a base, in organic synthesis.
The solid is diamagnetic. In terms of their coordination spheres, copper centres are 2-coordinated and the oxides are tetrahedral. The structure thus resembles in some sense the main polymorphs of SiO2, and both structures feature interpenetrated lattices. Copper(I) oxide dissolves in concentrated ammonia solution to form the colourless complex [Cu(NH3)2]+, which is easily oxidized in air to the blue [Cu(NH3)4(H2O)2]2+.
Phillips, loc.cit. It also, for a while, bucked the trend towards boyish fashion that, as after the First World War, tended to follow major conflicts.With reference to the colourless "utility" garments that became commonplace in Britain during the war, Phillips (loc.cit.) quotes an expert of the time at London's Victoria and Albert Museum as asserting that "men will feel oppressed and frightened by excessive femininity when they return from war".
The conjugate base of sulfuric acid (H2SO4)—a dense, colourless, oily, corrosive liquid—is the hydrogen sulfate ion (), also called the bisulfate ion. Sulfuric acid is classified as a strong acid; in aqueous solutions it ionizes completely to form hydronium ions (H3O+) and hydrogen sulfate (). In other words, the sulfuric acid behaves as a Brønsted–Lowry acid and is deprotonated. Bisulfate has a molar mass of 97.078 g/mol.
Itaconic anhydride is a colourless, crystalline solid which dissolves in many polar organic solvents and hydrolyzes with water forming itaconic acid. The substance is recommended to be stored in a dry and inert atmosphere. At temperatures above its melting point, itaconic anhydride is converted to citraconic anhydride. Even at significantly lower temperatures, such as in boiling chloroform, this isomerization can take place in the presence of tertiary amines.
The idea of food as it relates to culture has also been commented upon, with Vera Regan stating that Wah uses food as a way to connect his commentary to "tie him to his family, his culture, and his identity". Of the book's title, Pauline Butling described that being in the "Diamond Grill" meant to be in "[a] precious and yet contradictory space of interrogation, to be either 'colourless or tinted'".
Reddish-yellow edges overlap blue-cyan edges to form green. At Goethe's time, it was generally acknowledged that, as Isaac Newton had shown in his Opticks in 1704, colourless (white) light is split up into its component colours when directed through a prism.Karl Robert Mandelkow: Goethes Briefe (Goethe's Letters). 2. edition. Vol. 2: Briefe der Jahre 1786–1805 (Letters of the years 1786–1805). Christian Wegner publishers, Hamburg 1968, p. 528\.
The fully-grown caterpillar of Niphopyralis aurivillii are 6 to 7.5 mm long and 1.5 mm thick, and is tapers only slightly towards the ends. The body has a yellow-white colour, with head and pronotum somewhat darker. The entire body is diffusely covered with long, soft, colourless chaetae. The head is about two thirds the breadth of the pronotum, almost twice as long as broad, and tapered towards the front.
It tends to cause rotting in fruits that are stored at . The conidia are colourless and have a slimy coating. G. candidum is also found occasionally in the human gut, feces, sputum and on skin. The fungus grows in soil, water, sewage, various plant substrates, baker's dough, husks of fermentation, bread, milk and milk products The optimal temperature for growth is with a pH range of 5.0–5.5.
The wilted leaves often cover the plant entirely, which then appears to be almost dead. During the wet season, this leaf cover absorbs water rapidly, becoming turgid and pale green. As shown in the illustrations, the shape and colour of the turgid leaves also show that the species is a window plant: its leaf tips have panels that are practically colourless and transparent, admitting light to the chloroplasts deep inside.
Most species reach only 30–35 mm in length (max 45 mm). Coloration varies considerably within and between species but common patterns are pale cream, with or without darker flecks (never stripes), and a more uniform light gray or brown to black-brown. Mucus is usually colourless but in some species includes a white deposit when the slug has been disturbed. No keel continues from the tail along the back.
Reduction of BCl3 to elemental boron is conducted commercially (see below). In the laboratory, when boron trichloride can be converted to diboron tetrachloride by heating with copper metal: :2 BCl3 \+ 2 Cu → B2Cl4 \+ 2 CuCl B4Cl4 can also be prepared in this way. Colourless diboron tetrachloride (m.p. -93 °C) is a planar molecule in the solid, (similar to dinitrogen tetroxide, but in the gas phase the structure is staggered.
Zivania or zivana ( Turkish: Zibaniya) is a Cypriot pomace brandy produced from the distillation of a mixture of grape pomace and local dry wines made from Xynisteri and Mavro grapes. The name of zivania is derived from zivana () which means pomace in the Greek dialect of Cyprus. Zivania is colourless and alcoholic with a light aroma of raisins. Its alcohol content varies, with 45% by volume being the typical value.
Peripatoides is a genus of velvet worms in the Peripatopsidae family. These animals are nocturnal hunters that spit glue to trap their prey. In New Zealand species of Peripatoides have 14, 15 or 16 pairs of legs. Female Peripatoides produce eggs that are fertilized internally and babies develop inside their mother until large enough to be born, in batches of 4-6, as colourless miniatures of the parents.
Nitrosylsulfuric acid is the chemical compound with the formula NOHSO4. It is a colourless solid that is used industrially in the production of caprolactam, and was formerly part of the lead chamber process for producing sulfuric acid. The compound is the mixed anhydride of sulfuric acid and nitrous acid. In organic chemistry, it is used as a reagent for nitrosating, as a diazotizing agent, and as an oxidizing agent.
So this is 'a good violent murder with lots of blood.' But there is, on the other hand, another departure from Mrs Christie's earlier stories which must be regretted. M. Poirot in his retirement is becoming too much of a colourless expert. One feels a nostalgic longing for the days when he baited his 'good friend' and butt, Hastings, when he spoke malaprop English and astonished strangers by his intellectual arrogance.
Many external factors can influence colour: light, temperature, pH, sugars and metals. There is a method to turn petunia flowers from white to transparent. The petunia flower is immersed into a flask of water, connected to a vacuum pump, after which the flower appeared colourless. The white colour is expressed by the air present in the vacuoles that absorb the light, without air the flower loses the white colour.
Penicillium sp. under bright field microscopy (10 × 100 magnification) with lactophenol cotton blue stain The thallus (mycelium) consists of highly branched networks of multinucleated,usually colourless hyphae, with each pair of cells separated by a septum. Conidiophores are at the end of each branch accompanied by green spherical constricted units called conidia. These propagules lay a significant role in reproduction; conidia are the main dispersal strategy of these fungi.
Higher members of the homologous series SinH2n+2 formed in these reactions were subsequently identified by Carl Somiesky (sometimes spelled "Karl Somieski") and Alfred Stock. At standard temperature and pressure, disilane is a colourless, acrid gas. Disilane and ethane have similar structures, although disilane is much more reactive. Other compounds of the general formula Si2X6 (X = hydride, halide, alkyl, aryl, and mixtures of these groups) are called disilanes.
The head and body colour is black, with the melanophores mostly arranged in two longitudinal bars, and the fins are colourless. Females grow to a length of about while free-living males may achieve . The males are similar to other members of the genus but can be distinguished from them by the pigmentation, with melanophores concentrated in two longitudinal bars, and by the lack of sphenotic spines (above the eyes).
Tuesday, May 26, 2020 The technology for water-jet printing was developed by a team of Chinese scientists led by Sean Xiao-An Zhang, a chemistry professor at Jilin University in China. To create rewritable paper the researchers used four oxazolidines. Some of the isomers of these oxazolidines are colourless in the absence of water. But when the paper is wetted the water changes the dyes’ absorption of visible light.
Inocybe maculata has thin-walled cheilocystidia, which are clavate (club-shaped), lack encrustation at the apex, and are colourless. The basidia are also clavate, and can be two-, three- or four-spored, and measure from 15 to 30 micrometres (μm) by 5 to 9 μm. The sterigmata (the narrow horns on the end of the basidia which hold the spores) are 4 to 5 μm long. It lacks pleurocystidia.
Allyl alcohol (IUPAC name: prop-2-en-1-ol) is an organic compound with the structural formula CH2=CHCH2OH. Like many alcohols, it is a water-soluble, colourless liquid. It is more toxic than typical small alcohols. Allyl alcohol is used as a raw material for the production of glycerol, but is also used as a precursor to many specialized compounds such as flame-resistant materials, drying oils, and plasticizers.
In 1915, Curie produced hollow needles containing "radium emanation", a colourless, radioactive gas given off by radium, later identified as radon, to be used for sterilizing infected tissue. She provided the radium from her own one-gram supply. It is estimated that over a million wounded soldiers were treated with her X-ray units. Busy with this work, she carried out very little scientific research during that period.
Members of Vitreoscilla are obligate aerobic bacteria, which are morphologically colourless filaments that contain cells with diameters of 1-3 μm and 1-12 μm long. Each filament may contain from 1 to 40 cells. Locomotion is by gliding, and no special locomotor organelles are present. The cell walls are composed of the amino acids alanine, glutamate, and diaminopimelic acid, with approximate molar ratios of 2:1:1.
1-Hexene (hex-1-ene) is an organic compound with the formula C6H12. It is an alkene that is classified in industry as higher olefin and an alpha-olefin, the latter term meaning that the double bond is located at the alpha (primary) position, endowing the compound with higher reactivity and thus useful chemical properties. 1-Hexene is an industrially significant linear alpha olefin. 1-Hexene is a colourless liquid.
Dexpanthenol Panthenol is an odourless, slightly bitter, highly viscous, transparent and colourless liquid at room temperature, but salts of pantothenic acid (for example sodium pantothenate) are powders (typically white). It is easily soluble in water and alcohol, moderately soluble in diethyl ether, soluble in chloroform (1:100), in propylene glycol, and slightly soluble in glycerin. Panthenol's expanded chemical formula is HO–CH2–C(CH3)2–CH(OH)–CONH–CH2CH2CH2–OH.
The leaves are opposite, the shape and size of juvenile leaves often bearing little resemblance to the adult leaves. The latex may be clear and colourless, pale yellow or milky white. The flowers are green, white, cream, yellow, orange, red, pink or brown, sometimes with contrasting markings. These are followed by elongated pod-like capsules, the two follicles eventually separating to reveal numerous seeds with long, silky hairs.
Argon's name is taken from the colourless chemical element Argon, meaning that the group is "not limited to a single color" and they can "absorb multiple genres". The name is also an acronym for "Art Go On", meaning that "art continues". Argon released their first single album, Master Key, through various platforms on March 11, 2019. They held their debut showcase at the Ilji Art Hall in Gangnam the same day.
These are localized white spots on skin which may affect any area of the body, but these white spots are quite stable lesions. In the majority of patients, the lesions are not completely achromic, but are hypopigmented and resemble splashed paint. The individual lesions are permanent and there are no effective therapies for re- pigmenting this nevus. If there is hair in an affected area, it is usually colourless or white.
The peridium is an iridescent, consistently membranous layer. It is smooth on the edges and partly smooth, partly veined and mostly irregularly covered with the small hollows, which have a diameter from 0.4 to 0.8 µm and can be thickened on the edge. Dictydian granules are found in the shape darker or colourless pellets, which have a diameter from 0.8 to 1,8 µm. A capillitium or pseudocapillitium is lacking.
Potassium cyanate is an inorganic compound with the formula KOCN (sometimes denoted KCNORecreation of Wöhler’s Synthesis of Urea: An Undergraduate Organic Laboratory Exercise James D. Batchelor, Everett E. Carpenter, Grant N. Holder, Cassandra T. Eagle, Jon Fielder, Jared Cummings The Chemical Educator 1/Vol .3,NO.6 1998 ISSN 1430-4171 Online article ). It is a colourless solid. It is used to prepare many other compounds including useful herbicide.
At standard ambient temperature and pressure, trifluoroperacetic acid is a colourless liquid with a boiling point of 162 °C. It is soluble in acetonitrile, dichloromethane, diethyl ether, and sulfolane, and readily reacts with water. Like all peroxy acids, it is potentially explosive and requires careful handling. It is not commercially available, but can be made in the lab and stored for up to several weeks at −20 °C.
This diamond had some inclusions, yet it was an unmistakably colourless gem. The diamond did not display a definite crystallographic habit and was often incorrectly referred to as a 'cleavage piece'. If a resin model of the diamond is studied however, one would find no evidence of mechanical or natural cleavage on the diamond. The morphology of this diamond was due to plastic deformation during the eruption phase of the kimberlite.
Garnet species are found in many colours including red, orange, yellow, green, blue, purple, pink, brown, black and colourless, with reddish shades most common. A sample showing the deep red color garnet can exhibit. Garnet species' light transmission properties can range from the gemstone-quality transparent specimens to the opaque varieties used for industrial purposes as abrasives. The mineral's luster is categorized as vitreous (glass-like) or resinous (amber-like).
Rockwell, T. H., Safford, R. R. (1969): An evaluation of rear-end signal system characteristics in night driving, pp. 12–13, 17, 33, 41–42 A 2008 US study by the National Highway Traffic Safety Administration suggests vehicles with amber rear signals rather than red ones are up to 28% less likely to be involved in certain kinds of collisions, a followup 2009 NHTSA study determined there is a significant overall safety benefit to amber rather than red rear turn signals, US studies in the early 1990s demonstrated improvements in the speed and accuracy of following drivers' reactions to stop lamps when the turn signals were amber rather than red, and NHTSA determined in 2015 that amber rear turn signals can be provided at comparable cost to red ones. There is some evidence that turn signals with colourless clear lenses and amber bulbs may be less conspicuous in bright sunlight than those with amber lenses and colourless bulbs.
Phenylglyoxylic acid is the organic compound with the formula C6H5C(O)CO2H. The conjugate base, known as benzoylformate is the substrate of benzoylformate decarboxylase, a thiamine diphosphate-dependent enzyme: :benzoylformate + H+ benzaldehyde + CO2 It is a colourless solid with a melting point of 64–66 °C and is moderately acidic (pKa = 2.15). Phenylglyoxylic acid can be synthesized by oxidation of mandelic acid with potassium permanganate. An alternative synthesis involves hydrolysis of benzoyl cyanide.
Acrolein (systematic name: propenal) is the simplest unsaturated aldehyde. It is a colourless liquid with a piercing, acrid smell. The smell of burnt fat (as when cooking oil is heated to its smoke point) is caused by glycerol in the burning fat breaking down into acrolein. It is produced industrially from propylene and mainly used as a biocide and a building block to other chemical compounds, such as the amino acid methionine.
This almost backfires, as Tripti turns out to be a very open-minded girl who has no hang-ups about her own past and admits to having been in relationships before. Now stuck in a lie, Mandar has to continue projecting himself as an orthodox, colourless man. All the same, the two continue to meet and start liking each other. In due course, Kshitij is killed in an encounter with insurgents in Kashmir.
Thus, every chlorine is in the middle of a cube formed by caesium atoms and every caesium is in the middle of a cube formed by chlorine. Most caesium compounds contain the element as the cation , which binds ionically to a wide variety of anions. One noteworthy exception is the caeside anion (), and others are the several suboxides (see section on oxides below). Salts of Cs+ are usually colourless unless the anion itself is coloured.
This is diagnostic of E. coli. The organism is also lysine positive, and grows on TSI slant with a (A/A/g+/H2S-) profile. Also, IMViC is {+ + – -} for E. coli; as it is indole- positive (red ring) and methyl red-positive (bright red), but VP-negative (no change-colourless) and citrate-negative (no change-green colour). Tests for toxin production can use mammalian cells in tissue culture, which are rapidly killed by shiga toxin.
Castelli district. Apart from the previously mentioned older districts of the modern part of the town, several new residential areas have been developed during the 20th century, like Agios Ioannis, Koumbes, Lentariana etc. Some part—but not the biggest—of the city centre is dominated by colourless medium-height block buildings, typical of the urbanization period of Greece (1950-1970). However, there are still some neoclassical houses, especially in the eastern part of Chania.
The spores are often yellow but can range anywhere from colourless or white to pink and reddish brown. The capillitium is the defining feature of the order Trichida. It is often described as “decorated” or “ornamental” due to features like spirals, warts, and spines. The development of the capillitium in Trichida is formed through tubular vacuoles within the plasmodium that are organized into the desired shape of the final capillitium, including potential branches and spirals.
This liquid is colourless as it does not contain pigments; for this reason, it serves only a limited role in oxygen transport. Two different types of blood cells (or haemocytes) circulate in the fluid: amoebocytes and nephrocytes. The amoebocytes probably function in protection from bacteria and other foreign bodies; in some species, they also play a role in reproduction. Nephrocytes absorb toxins or convert them into a form suitable for elimination by the nephridia.
3-Methyl-3-octanol (systematically named 3-methyloctan-3-ol) is an organic compound with the chemical formula CH3(CH2)4C(CH3)(CH2CH3)OH (also written as ). This simple tertiary alcohol is a clear colourless liquid under standard conditions, and is tasteless. It is used in the food industry as a flavouring agent as it contributes to the flavour of roast beef. It is known to be biochemically produced by the Antrodia camphorata fungus.
It includes a variety of musical styles and dynamics ranging from extremely soft to extremely loud, using an orchestra with a greatly expanded percussion section including oil drums, steel discs, marble plates, pots, pans, and bottles. There are just two short insertions of electronic music, which were realised with the assistance of Karl-Erik Welin. They are overlaid with sparse orchestral music played live, and consist of vague, almost deliberately colourless sounds .
Workers are up to long. The thorax is constricted and the abdomen inflated, giving them a plump appearance. The head capsule is colourless and the abdomen transparent, so that the gut and its contents can be seen through the cuticle, giving them an overall greyish-colour. Soldiers are a similar size but the larger head capsule is pigmented and armed with black, crescent-shaped mandibles, each with a distinctive tooth on its inner surface.
Methanesulfonyl chloride (mesyl chloride) is an organosulfur compound with the formula CH3SO2Cl. Using the organic pseudoelement symbol Ms for the methanesulfonyl (or mesyl) group CH3SO2, it is frequently abbreviated MsCl in reaction schemes or equations. It is a colourless liquid that dissolves in polar organic solvents but is reactive toward water, alcohols, and many amines. The simplest organic sulfonyl chloride, it is used to make methanesulfonates and to generate the elusive molecule sulfene (methylenedioxosulfur(VI)).
Sulfur trioxide pyridine complex is the compound with the formula C5H5NSO3. It is a colourless solid that dissolves in polar organic solvents. It is the adduct formed from the Lewis base pyridine and the Lewis acid sulfur trioxide.

Tidwell "Sulfur Trioxide–Pyridine" Encyclopedia of Reagents for Organic Synthesis 2001, John Wiley & Sons. .
The Kızılırmak toothcarp shows sexual dimorphism like all Aphanius species. Males have nine to twelve dark grey-black bars on the sides of the body, a dark blue-black dorsal fin and colourless to yellow caudal and anal fin with two or three black lines at the margins. Females have silver-grey body with a large number of dark grey spots. The largest spot is always centered on the base of the caudal fin.
Vinylacetylene is the organic compound with the formula C4H4. The colourless gas was once used in the polymer industry. It is composed of both alkyne and alkene groups and is the simplest enyne. Vinylacetylene is extremely dangerous because in high enough concentrations (typically > 30 mole percent, but pressure dependent) it can auto-detonate (explode without air being present) especially at elevated pressures, such as those seen in chemical plants processing C4 hydrocarbons.
Antimony pentafluoride is the inorganic compound with the formula SbF5. This colourless, viscous liquid is a valuable Lewis acid and a component of the superacid fluoroantimonic acid, the strongest known acid, formed when mixing liquid HF with liquid SbF5 in a 2:1 ratio. It is notable for its Lewis acidity and its ability to react with almost all known compounds.Olah, G. A.; Prakash, G. K. S.; Wang, Q.; Li, X.-y.
Rhisiart has been allowed a visit from Tegolin, who tells him that, by sleeping with the custodian, she has been able to obtain a guarantee that Rhisiart's life will be spared. She gives Rhisiart a phial containing a colourless liquid which she claims is "certain death". The two prisoners are interviewed by King Henry and the Archbishop of Canterbury. Rhisiart is condemned to the Tower of London and Brut to be burned at the stake.
Its spicules are slender and needle-like; the right spicule is longer than the left spicule or in some cases both spicules are equal in length. Its gubernaculum is narrow and long, with its proximal half being dorsally bent. The distal part of the gubernaculum possesses a transverse lamella-like structure on its dorsal side. The spicules and gubernaculum are well sclerotized, which are orange-coloured, the anterior part of which is colourless.
His first two releases that year were the comedies Deewane Huye Paagal and Vaah! Life Ho Toh Aisi!, both of which were largely panned. The former was plagiarised from the Hollywood film There's Something About Mary in which Kapoor played one of Rimi Sen's love interests; the critic Khalid Mohamed found Kapoor to be "the only likeable element in this travesty" but Namrata Joshi of Outlook labelled him "colourless" and criticised his pairing with Sen.
In4Br7 is near colourless with a pale greenish yellow tint. It is light sensitive (like TlCl and TlBr) decaying to InBr2 and In metal. It is a mixed salt containing the In and In anions balanced by In+ cations. It is formulated InI5(InIIIBr4)2(InIIIBr6) The reasons for the distorted lattice have been ascribed to an antibonding combination between doubly filled, non-directional indium 5s orbitals and neighboring bromine 4p hybrid orbitals.
1,2-Benzenedithiol is the organosulfur compound with the formula CH(SH). This colourless viscous liquid consists of a benzene ring with a pair of adjacent thiol groups. The conjugate base of this diprotic compound serves as chelating agent in coordination chemistry and a building block for the synthesis of other organosulfur compounds.Karlin, K. D.; Stiefel, E. I., Eds. “Progress in Inorganic Chemistry, Dithiolene Chemistry: Synthesis, Properties, and Applications” Wiley-Interscience: New York, 2003.
In 1882, Charles Chilton collected specimens of P. subterraneus from groundwater at his farm near Eyreton, Canterbury, and later obtained specimens from various depths in Lincoln, Winchester and St. Albans. These animals were colourless and lacked eyes, and were described as a new species in the genus Calliope. Chilton later acquired specimens from the Porter River at Castle Hill, Canterbury, from Lake Wakatipu, Otago, from Lake Taupo on the North Island and from Otautau, Southland.
Macrostomum rostratum is colourless and between in length. There are a pair of small eyes at the anterior end and a longitudinal-slit mouth on the ventral surface just behind these. A short pharynx leads from the mouth to a simple gut. Also on the ventral surface, the female gonopore, which is shaped like a rosette, is in front of the male gonopore and penis which are half way along the flatworm.
Nitrogen trichloride All four simple nitrogen trihalides are known. A few mixed halides and hydrohalides are known, but are mostly unstable; examples include NClF2, NCl2F, NBrF2, NF2H, NFH2, NCl2H, and NClH2.Greenwood and Earnshaw, pp. 438–42 Five nitrogen fluorides are known. Nitrogen trifluoride (NF3, first prepared in 1928) is a colourless and odourless gas that is thermodynamically stable, and most readily produced by the electrolysis of molten ammonium fluoride dissolved in anhydrous hydrogen fluoride.
The star-shaped flowers are whitish with yellow glistening glands and scarlet anther flaps. The glands at the base of the stamens in L. novae-zelandiae secrete nectar that accumulates at the base of the flower. This attracts a large number of bees, blowflies, small flightless animals, and Bombyliidae to the flowers. The nectar is visible as a colourless liquid which has a glistening appearance to the outer faces of the glands.
Heating a mixture of anhydrous copper(II) acetate and copper metal affords copper(I) acetate: :Cu + Cu(OAc)2 → 2 CuOAc Unlike the copper(II) derivative, copper(I) acetate is colourless and diamagnetic. "Basic copper acetate" is prepared by neutralizing an aqueous solution of copper(II) acetate. The basic acetate is poorly soluble. This material is a component of verdigris, the blue-green substance that forms on copper during long exposures to atmosphere.
The indicator used in this reaction is a starch solution where amylose forms a blue to black solution with iodine and is colourless where iodine is titrated. A precaution that should be observed is to add the starch indicator solution only near the end point (the end point is near when fading of the yellowish iodine colour occurs) because at high iodine concentration starch is decomposed to products whose indicator properties are not entirely reversible.
The last digit(s) on Copic Markers represent a marker's colour intensity (aka how bright that colour is). These numbers are split between 12 levels (000, 00 and 0-9). Markers that fall closer to the 0 range are lighter in value, and become darker the closer they shift toward 9. Markers that are 000 and 00 in nature are often more transparent as they have a higher concentration of colourless blender alcohol-based fluid.
Ozone is a colourless or pale blue gas, slightly soluble in water and much more soluble in inert non-polar solvents such as carbon tetrachloride or fluorocarbons, in which it forms a blue solution. At , it condenses to form a dark blue liquid. It is dangerous to allow this liquid to warm to its boiling point, because both concentrated gaseous ozone and liquid ozone can detonate. At temperatures below , it forms a violet-black solid.
Roman glass production developed from Hellenistic technical traditions, initially concentrating on the production of intensely coloured cast glass vessels. However, during the 1st century AD the industry underwent rapid technical growth that saw the introduction of glass blowing and the dominance of colourless or 'aqua' glasses. Production of raw glass was undertaken in geographically separate locations to the working of glass into finished vessels,Fleming, S. J., 1999. Roman Glass; reflections on cultural change.
Glassblowing allowed glass workers to produce vessels with considerably thinner walls, decreasing the amount of glass needed for each vessel. Glass blowing was also considerably quicker than other techniques, and vessels required considerably less finishing, representing a further saving in time, raw material and equipment. Although earlier techniques dominated during the early Augustan and Julio-Claudian periods,Grose, D. F., 1991. Early Imperial Roman cast glass: The translucent coloured and colourless fine wares.
Benzenesulfonyl chloride is an organosulfur compound with the formula C6H5SO2Cl. It is a colourless viscous oil that dissolves in organic solvents, but reacts with compounds containing reactive N-H and O-H bonds. It is mainly used to prepare sulfonamides and sulfonate esters by reactions with amines and alcohols, respectively. The closely related compound toluenesulfonyl chloride is often preferred analogue because it is a solid at room temperature and easier to handle.
Ethylaluminium sesquichloride, also called EASC, is an industrially important organoaluminium compound used primarily as a precursor to triethylaluminium and as a catalyst component in Ziegler–Natta type systems for olefin and diene polymerizations. Other applications include use in alkylation reactions and as a catalyst component in linear oligomerization and cyclization of unsaturated hydrocarbons. EASC is a colourless liquid, spontaneously combustible in air and reacts violently when in contact with water and many other compounds.Aluminum alkyls.
A jester in King Shrewd's court, the Fool (or Beloved, as his mother named him) frequently speaks in riddles, and at times appears to be prescient. Although the Fool frequently teases him, Fitz considers him a close friend. The Fool is extremely pale, almost albino, with white hair and colourless eyes that many people find hard to meet. However, he gradually darkens throughout the books, appearing as golden or "tawny" in Fool's Errand.
The oceans are estimated to release 1–2 million tons of bromoform and 56,000 tons of bromomethane annually. Bromine addition to alkene reaction mechanism An old qualitative test for the presence of the alkene functional group is that alkenes turn brown aqueous bromine solutions colourless, forming a bromohydrin with some of the dibromoalkane also produced. The reaction passes through a short-lived strongly electrophilic bromonium intermediate. This is an example of a halogen addition reaction.
Illustration of the morello cherry Because morellos were originally grown in the Black Forest regions of Germany, kirschwasser is believed to have originated there. Kirschwasser is colourless because it is either not aged in wood or is aged in barrels made of ash. It may have been aged in paraffin-lined wood barrels or in earthenware vessels.' In France and in English-speaking countries, clear fruit brandies are known as eaux de vie.
Origin of this essential oil, the tea tree, Melaleuca alternifolia. Tea tree plantation, Coraki, New South Wales. Tea tree oil, also known as melaleuca oil, is an essential oil with a fresh camphoraceous odor and a colour that ranges from pale yellow to nearly colourless and clear. It is derived from the leaves of the tea tree, Melaleuca alternifolia, native to southeast Queensland and the northeast coast of New South Wales, Australia.
Tris(2-aminoethyl)amine is the organic compound with the formula N(CH2CH2NH2)3. This colourless liquid is soluble in water and is highly basic, consisting of a tertiary amine center and three pendant primary amine groups. Abbreviated tren, it is the archetypal tripodal ligand of interest in coordination chemistry. Tren is a C3-symmetric, tetradentate chelating ligand that forms stable complexes with transition metals, especially those in the 2+ and 3+ oxidation states.
The conidia are produces at the end of short stalks ranging from 2.5 to 7.5 μm in length and 1.5 to 2.5 μm in width. The conidia range from 3 to 12.5 μm long and 1.3 to 3.5 μm wide. and are released by rhexolytic dehiscence in which the walls of cell compartments adjacent to conidia erode, freeing the conidia from attached hyphae. The conidia are colourless to pale yellow and smooth-walled.
Colonies of C. bostrychodes can grow 2.5 to 3.5 mm daily, usually without developing aerial mycelium. It can sometimes grow with pale green exudates and a green or uncoloured reverse. When young, C. bostrychodes appears as colourless and dextrinoid, but upon maturity, turns pale bluish grey or olivaceous with an apical germ pore . C. bostrychodes often are darkened around the 25 to 35 μm wide ostiolar pore, giving the genus its name of Collariella.
These fruiting bodies are relatively large, ranging from 290–500 μm in diameter, and are either colourless or have a light brown pigment. The presence of the ascomata is characteristic of all members of the Ascomycota. The ascomata are smooth and have thick, enclosed walls lacking any openings. They reach full maturity after 8–10 days of colonial growth at optimal temperatures and eventually burst to release the asci contained within them.
The difference between beryl, aquamarine, and emerald is determined by the colouring and the peculiar shade of each. Beryl, though sometimes colourless (not white), is usually of a light blue bordering on a yellowish green; emerald is more transparent and of a finer hue than beryl. Beryl is also black in colour. As a gem, it is considered more beautiful, and therefore more expensive - aqua marine is a beautiful sea-green variety.
Decolourizing material used to be referred to as "glassmakers soap" and neutralized unwanted shades of colour. Additives of the mineral manganese dioxide or arsenic, allowed the glass to appear colourless. By using other additives, glass could be coloured, especially in cobalt-blue, purple, red, green or white. The end of the Heidelbach Glassworks around 1827 was mainly due to its outdated smelting technology and strong competition from the Bohemian glass industry at that time.
Triphenylstibine is the chemical compound with the formula Sb(C6H5)3. Abbreviated SbPh3, this colourless solid is often considered the prototypical organoantimony compound. It is used as a ligand in coordination chemistry and as a reagent in organic synthesis. Like the related molecules triphenylphosphine and triphenylarsine, SbPh3 is pyramidal with a propeller- like arrangement of the phenyl groups. The Sb-C distances average 2.14-2.17 Å and the C-Sb-C angle are 95°.
Dichloro(1,5-cyclooctadiene)platinum(II) (Pt(cod)Cl2) is an organometallic compound of platinum. This colourless solid is an entry point to other platinum compounds through the displacement of the cod and/or chloride ligands. It is one of several complexes of 1,5-cyclooctadiene. Dichloro(1,5-cyclooctadiene)platinum(II) is prepared by treating potassium tetrachloroplatinate with the diene: :K2PtCl4 \+ C8H12 → PtCl2C8H12 \+ 2 KCl According to X-ray crystallography, the complex is square planar.
Methanol, also known as methyl alcohol amongst other names, is a chemical with the formula CH3OH (a methyl group linked to a hydroxyl group, often abbreviated MeOH). It is a light, volatile, colourless, flammable liquid with a distinctive alcoholic odour similar to that of ethanol. A polar solvent, methanol acquired the name wood alcohol because it was once produced chiefly by the destructive distillation of wood. Today, methanol is mainly produced industrially by hydrogenation of carbon monoxide.
A dish topped with snail caviar A close-up view of snail caviar Snail caviar, also known as escargot caviar or escargot pearls, is a type of caviar that consists of fresh or processed eggs of land snails. It is a luxury gourmet speciality produced in France and Poland. They were also a delicacy in the ancient world, also known as "Pearls of Aphrodite" for their supposed aphrodisiac properties. In their natural state, the eggs are colourless.
Potassium bifluoride is the inorganic compound with the formula KHF2. This colourless salt consists of the potassium cation and the bifluoride (HF2−) anion. The salt is used in etchant for glass. Sodium bifluoride is related and is also of commercial use as an etchant as well as in cleaning products.Jean Aigueperse, Paul Mollard, Didier Devilliers, Marius Chemla, Robert Faron, Renée Romano, Jean Pierre Cuer, "Fluorine Compounds, Inorganic" in Ullmann’s Encyclopedia of Industrial Chemistry 2005 Wiley-VCH, Weinheim.
A fiscally used postage and revenue stamp of the Bahamas, 1863 Very few revenue stamps of the Bahamas have been issued, as most of the time dual- purpose postage and revenue stamps were used for fiscal purposes. They were used as such from around the 1860s to at least the 1950s. A couple of revenue- only impressed duty stamps embossed in vermilion ink are known used in the 1950s. Similar stamps but with colourless embossing might also exist.
Accessed April 20, 2009. A colourless, odourless liquid, it is used as a chemical weapon due to its extreme potency as a nerve agent. Exposure is lethal even at very low concentrations, where death can occur within one to ten minutes after direct inhalation of a lethal dose, due to suffocation from respiratory paralysis, unless antidotes are quickly administered. People who absorb a non-lethal dose, but do not receive immediate medical treatment, may suffer permanent neurological damage.
Methyl trifluoromethanesulfonate, also commonly called methyl triflate and abbreviated MeOTf, is the organic compound with the formula CF3SO2OCH3. It is a colourless liquid which finds use in organic chemistry as a powerful methylating agent. The compound is closely related to methyl fluorosulfonate (FSO2OCH3). Although there has yet to be a reported human fatality, while several cases were reported for methyl fluorosulfonate (LC50 (rat, 1 h) = 5 ppm), methyl triflate is expected to have similar toxicity based on available evidence.
The music of Sponsus has been praised by Rafaello Monteross for "redeem[ing] the anonymous poet's colourless paraphrase of the gospel text from its generic inexpressiveness."Shakespeare und die Tradition des Volkstheaters (Berlin: 1967), quoted in Dronke, p. 9. The melodic phrasing is varied, but only four different melodies are used for the entire play, though none of them is liturgical, and none form motifs. The entire score is original and is recorded in Aquitainian neumes.
Finally some white wines can be victims of Rosissement (pinking). This phenomenon manifests itself in a light rosé colouration of the wine and takes the appearance of a "stained" wine or one that is contaminated by the presence of anthocyanins from red wine. Yet this is not so: the phenomenon is due to the presence of a normally colourless dissolved polyphenol which turns pink due to oxidation. An infusion of PVPP generally eliminates the substrate of oxidation.
The Williams pear is used in making both Poire Williams, a colourless brandy, and Belle de Brillet, an infused cognac. The pear is also very popular in western Balkans where it is distilled into brandy known as Viljamovka, similar to Poire Williams but often with higher alcohol percentage. Some producers of Viljamovka include an entire pear inside each bottle. This is achieved by attaching the bottle to a budding pear tree so that the pear will grow inside it.
According to the Historia Augusta, Hadrian composed the following poem shortly before his death:Historia Augusta, Hadrian Dio 25.9; Antony Birley, p. 301 :Animula, vagula, blandula :Hospes comesque corporis :Quae nunc abibis in loca :Pallidula, rigida, nudula, :Nec, ut soles, dabis iocos... :::P. Aelius Hadrianus Imp. :Roving amiable little soul, :Body's companion and guest, :Now descending for parts :Colourless, unbending, and bare :Your usual distractions no more shall be there... The poem has enjoyed remarkable popularity,see e.g.
Printings of stamps with the new watermark were sent to Saint Kitts, Dominica and Antigua. Dual-purpose postage and revenue stamps of the Leeward Islands were also valid for fiscal use on the islands from 1890 to the 1950s. The Leeward Islands also had colourless impressed duty stamps which were directly embossed onto documents. Designs inscribed LEEWARD ISLANDS FEES and depicting an Imperial Crown and flowers were prepared in 1890, and they are known used in the 1930s.
"Structure functions", Progress in Particle and Nuclear Physics 66 (4) pp 727–781, The fundamental understanding of structure functions in terms of QCD is one of the outstanding problems in hadron physics. Why do quarks form colourless hadrons with only two stable configurations, proton and neutron? One important step towards answering this question is to characterize the internal structure of the nucleon. High energy electron scattering provides one of the most powerful tools to investigate this structure.
Van Slingelandt was succeeded after his death in office in 1736 by Anthonie van der Heim as Grand Pensionary, be it after a protracted power struggle. He had to promise in writing that he would oppose the resurrection of the stadtholderate. He was a compromise candidate, maintaining good relations with all factions, even the Orangists. He was a competent administrator, but of necessity a colourless personage, of whom it would have been unreasonable to expect strong leadership.
Alunogen (from French alun, “alum”), also called feather alum and hair salt is a colourless to white (although often coloured by impurities, such as iron substituting for aluminium) fibrous to needle-like aluminium sulfate mineral. It has the chemical formula Al2(SO4)3·17H2O. It is often found on the walls of mines and quarries as a secondary mineral. It can be found in the oxidation zones of some ore deposits as well as on burning coal dumps (i.e.
This microscopic feature may be used to help distinguish it from the similar-coloured C. adnatifolia and C. granulosa, which also bear non-amyloid spores, but lack cystidia. Species of Cystoderma (including orange-capped species such as Cystoderma amianthinum) have amyloid spores, in comparison to non-amyloid spores in C. cinnabarina and species of Cystodermella in general. This is determined by staining tissue with chemicals in the amyloid reaction—all Cystodermella species show a negative reaction (spores remain colourless).
1,2-Dichlorobenzene, or orthodichlorobenzene (ODCB), is an organic compound with the formula CHCl. This colourless liquid is poorly soluble in water but miscible with most organic solvents. It is a derivative of benzene, consisting of two adjacent chlorine atoms. It is mainly used as a precursor chemical in the synthesis of agrochemicals, as a preferred solvent for dissolving and working with fullerenes, as an insecticide, and in softening and removing carbon-based contamination on metal surfaces.
Its carapace is coloured mostly yellow-orange, with three white patches laterally. Its rostrum is reddish-orange and its orbital hoods translucent. The antennal and antennular peduncles are orange-red, while its mouthparts are mostly found to be colourless, except for the palp and caridean lobe of its first maxilliped, which are reddish. Its major and minor chelipeds are orange-red; the merus showing a distal white patch; chelae almost white on the tips of fingers.
Calcium nitrate, also called Norgessalpeter (Norwegian saltpeter), is an inorganic compound with the formula Ca(NO3)2. This colourless salt absorbs moisture from the air and is commonly found as a tetrahydrate. It is mainly used as a component in fertilizers but has other applications. Nitrocalcite is the name for a mineral which is a hydrated calcium nitrate that forms as an efflorescence where manure contacts concrete or limestone in a dry environment as in stables or caverns.
The smooth oval spores measure 12–15 by 5–6 μm, and sometimes have an internal oil drop. Basidia (spore-bearing cells) are club-shaped, four-spored, and measure 22–34 by 8–9 μm. The fusiform (fuse-shaped) cystidia are colourless with oil droplets, and have dimensions of 40–50 by 7–8 μm. Cap cuticle tissue is in the form of a trichoderm, where the outermost hyphae emerge roughly parallel, like hairs, perpendicular to the cap surface.
An example fatty alcohol Fatty alcohols (or long-chain alcohols) are usually high-molecular-weight, straight-chain primary alcohols, but can also range from as few as 4–6 carbons to as many as 22–26, derived from natural fats and oils. The precise chain length varies with the source. Some commercially important fatty alcohols are lauryl, stearyl, and oleyl alcohols. They are colourless oily liquids(for smaller carbon numbers) or waxy solids, although impure samples may appear yellow.
Trotsky and his supporters underestimated Molotov, as did many others. Trotsky called him "mediocrity personified", whilst Molotov himself pedantically corrected comrades referring to him as 'Stone Arse' by saying that Lenin had actually dubbed him 'Iron Arse'. However, this outward dullness concealed a sharp mind and great administrative talent. He operated mainly behind the scenes and cultivated an image of a colourless bureaucrat – for example, he was the only Bolshevik leader who always wore a suit and tie.
Boynton die? – the play is tepid and far too talkative. But it does give Miss Mary Clare a strong scene or two as the woman of the gimlet gaze, and Miss Carla Lehmann and Mr. Owen Reynolds both help pleasantly."The Observer 8 April 1945 (Page 2) The Guardian's issue of 2 April 1945 contained a review by "LH" in which he praised the character of Mrs Boynton but said that, "her death leaves the last act colourless.
Canada balsam, also called Canada turpentine or balsam of fir, is a turpentine made from the resin of the balsam fir tree (Abies balsamea) of boreal North America. The resin, dissolved in essential oils, is a viscous, sticky, colourless or yellowish liquid that turns to a transparent yellowish mass when the essential oils have been allowed to evaporate. Canada balsam is amorphous when dried. Since it does not crystallize with age, its optical properties do not deteriorate.
This unfolding will result in loss in enzymatic activity, which is understandably deleterious to continuing life-functions. An example of such is the denaturing of proteins in albumen from a clear, nearly colourless liquid to an opaque white, insoluble gel. Proteins capable of withstanding such high temperatures compared to proteins that cannot, are generally from microorganisms that are hyperthermophiles. Such organisms can withstand above 50 °C temperatures as they usually live within environments of 85 °C and above.
The dimensions of the Star of the South were 35 mm x 29 mm x 19 mm. The light reflected by the diamond is white, and the refracted light is of a rose tint. This is attributed to the prismatic form given to the crystal during its cutting. The Star of the South has a colour grading of light pinkish-brown, pink and brown being two colours that can show up in colourless diamonds of type IIa.
The fins are colourless. It has a gill raker count of 9-10 on the lower arm of first gill arch and there are 5 horizontal scale rows between the lateral line and the mid-dorsal scale row at the origin of the dorsal-fin. It can grow to up to 40 cm in length. This species can be found in large rivers during the dry season and migrates into medium-sized rivers during the monsoon.
Aspergillomarasmine A takes the form of colourless crystals. The chemical is insoluble in common organic solvents, but can dissolve in water under either basic or strongly acidic conditions. Anhydroaspergillomarasmine A, a lactam of aspergillomarasmine A, chemically called [1-(2-amino-2carboxyethyl)-6-carboxy-3-carboxymethyl-3-piperazinone], can also be found in Pyrenophora teres. The relative amount of these two toxins is dependent upon the pH of the growth medium, with lower pH favouring the lactam form.
In Guangdong, Wang increasingly branded himself as a bold reformer. He was instrumental in pushing Guangdong province, already dubbed China's "breeding ground of reform", towards even greater economic and political freedoms. China's Shenzhen starts spreading the news Additionally, Wang sought to diversify the province's economy away from manufacturing, and make Shenzhen an innovation hub for China's new economy. Wang's unique leadership style set him apart from normally colourless and risk-averse provincial administrators who parrot the party line.
Ribulose 1,5-bisphosphate (RuBP) is an organic substance that is involved in photosynthesis. It is a colourless anion, a double phosphate ester of the ketopentose (ketone-containing sugar with five carbon atoms) called ribulose. Salts of RuBP can be isolated, but its crucial biological function happens in solution.The topic is discussed in all biochemistry textbooks, this one is representative: Nelson, D. L.; Cox, M. M. "Lehninger, Principles of Biochemistry" 3rd Ed. Worth Publishing: New York, 2000. .
A bottle of Big Boss cashew feni Cashew feni was awarded Geographical Indication registration in 2009 as a speciality alcoholic beverage from Goa, described as a colourless, clear liquid that when matured in wooden barrels develops golden brown tint. This designation was achieved through the efforts of the Goa Cashew Feni Distillers & Bottlers Association and the Department of Science, Technology & Environment of the Government of Goa. The application of a G.I. for coconut feni has been neglected.
Bohemia, currently a part of the Czech Republic, became famous for its beautiful and colourful glass during the Renaissance. The history of Bohemian glass started with the abundant natural resources found in the countryside. Bohemian glass-workers discovered potash combined with chalk created a clear colourless glass that was more stable than glass from Italy. In the 16th century the term Bohemian crystal was used for the first time to distinguish its qualities from glass made elsewhere.
PVC compounds can be created with a very wide range of physical and chemical properties based on the types and amounts of plasticizers and other additives used. Additional selection criteria include their compatibility with the polymer, volatility levels, cost, chemical resistance, flammability and processing characteristics. These materials are usually oily colourless substances that mix well with the PVC particles. About 90% of the plasticizer market, estimated to be millions of tons per year worldwide, is dedicated to PVC.
Various techniques are used to achieve an etched surface in glass, whether for artistic effect, or simply to create a translucent surface. Acid etching is done using hexafluorosilicic acid (H2SiF6) which, when anhydrous, is colourless. The acid is prepared by dissolving silica in a mixture of hydroelectric acid (hydrochloric acid), quartz powder, calcium fluoride, and concentrated sulfuric acid derived after heating. Glass etching cream is used by hobbyists as it is generally easier to use than acid.
In humans and other animals chronic intake of silver products commonly leads to gradual accumulation of silver compounds in various parts of the body. As in photography (where silver is useful because of its sensitivity to light), exposure of pale or colourless silver compounds to sunlight decomposes them to silver metal or silver sulfides. Commonly these products deposit as microscopic particles in the skin, in effect a dark pigment. This condition is known as argyria or argyrosis.
M. Glendinning, R. MacInnes and A. MacKechnie, A History of Scottish Architecture: from the Renaissance to the Present Day (Edinburgh: Edinburgh University Press, 2002), , pp. 486–7. The most significant figure in the development of architecture in Scotland from the 1980s was the academic Charles McKean. He was secretary and treasurer of the Royal Incorporation of Architects in Scotland (RIAS) from 1979 to 1995. He argued against motorway expansion and the production of grey, colourless monoliths.
The colour on the body is dusky, with every scale having a spot of darker colour along its edge and on the caudal peduncle, these spots sometimes coalesce to create irregular, horizontal, fine bars. The fins on the body have a dusky membrane. The caudal fin is dusky at its base and the pelvic fins have a slight dusky colour while the pectoral fins are colourless. The maximum standard length is although the common standard length is .
Comparison of the boiling points of hydrogen halides and hydrogen chalcogenides; here it can be seen that hydrogen fluoride breaks trends alongside water. The hydrogen halides are colourless gases at standard conditions for temperature and pressure (STP) except for hydrogen fluoride, which boils at 19 °C. Alone of the hydrogen halides, hydrogen fluoride exhibits hydrogen bonding between molecules, and therefore has the highest melting and boiling points of the HX series. From HCl to HI the boiling point rises.
The ground state of has a bond length of 121 pm and a bond energy of 498 kJ/mol. It is a colourless gas with a boiling point of . It can be condensed from air by cooling with liquid nitrogen, which has a boiling point of . Liquid oxygen is pale blue in colour, and is quite markedly paramagnetic due to the unpaired electrons; liquid oxygen contained in a flask suspended by a string is attracted to a magnet.
Boron oxyfluoride glass is transparent and colourless. It is stable in dry air, but it is hygroscopic and in normal air becomes white and opaque. When heated the glass will encounter a glass transition temperature (Tg) at which it ceases to be a glass, and produces BF3 gas and a boron oxyfluoride with less fluorine is left behind. This glass transition temperature is determined from where the pressure of BF3 produced exceeds the strength of the glass.
Azulene is an organic compound and an isomer of naphthalene. Whereas naphthalene is colourless, azulene is dark blue. Two terpenoids, vetivazulene (4,8-dimethyl-2-isopropylazulene) and guaiazulene (1,4-dimethyl-7-isopropylazulene), that feature the azulene skeleton are found in nature as constituents of pigments in mushrooms, guaiac wood oil, and some marine invertebrates. Azulene has a long history, dating back to the 15th century as the azure-blue chromophore obtained by steam distillation of German chamomile.
It is difficult to detect because (like all the noble gases) it is colourless, odourless, and tasteless. Argon has a high ionisation energy (1520.6 kJ/mol), low electron affinity (estimated at −96 kJ/mol), and high electronegativity (3.2 AR). One interstitial compound of argon, Ar1C60 is a stable solid at room temperature. alt=Greyish lustrous block with uneven cleaved surface. Krypton has a density of 3.749 × 10−3 g/cm3, liquifies at −153.415 °C, and solidifies at −157.37 °C.
The group 6, chalcogen, and noble gas hexafluorides are colourless, but the other hexafluorides have colours ranging from white, through yellow, orange, red, brown, and grey, to black. The molecular geometry of binary hexafluorides is generally octahedral, although some derivatives are distorted from Oh symmetry. For the main group hexafluorides, distortion is pronounced for the 14-electron noble gas derivatives. Distortions in gaseous XeF6 are caused by its non-bonding lone pair, according to VSEPR theory.
On Czapek's agar, A. carneus colonies appear white at the beginning of development, progressing to variable shades of deep red, brownish red or yellow with age. The fungus produces conidiophores (250-400 μm) which are smooth and brown, yellow or colourless. Conidia are smooth, unpigmented and approximately spherical, with a diameter of 2.4-2.8 μm. Conidial heads are columnar in shape (150-200 μm x 25-35 μm) and initially white, appearing pale pink to brown in older cultures.
The reduction potential of a rubredoxin is typically in the range +50 mV to -50 mV. This iron-sulphur protein is an electron carrier, and it is easy to distinguish its metallic centre changes: the oxidized state is reddish (due to a ligand metal charge transfer), while the reduced state is colourless (because the electron transition has an energy of the infrared level, which is imperceptible to the human eye). Structural representation of a rubredoxin active site.
According to Goethe's concept, yellow undergoes a transition of light becoming darker when light reaches its peak, just as the Sun shines in the sky, it develops to a white light that is colourless. But the light deepens and evolves the yellow into an orange and then finally to a ruby red hue. Turner illustrates the process of yellow transitioning into phases of light by showing how, as the viewer moves away from the centre, the edges get darker.
The foot fringe is vertically striped and is often a different colour than the back. The head and tentacles are often darker than the rest of the body. The mucus is sticky and colourless or orange. Externally the species is not reliably distinguishable from several other species, including A. ater and A. vulgaris, and can be difficult to distinguish from less closely related species such as A. flagellus, especially in the Iberian Peninsula where further similar species exist.
Terbium(III) oxide, also known as terbium sesquioxide, is a sesquioxide of the rare earth metal terbium, having chemical formula . It is a p-type semiconductor when doped with calcium, and may be prepared by the reduction of in hydrogen at 1300 °C for 24 hours. Tb4O7+H2->2 Tb2O3+H2O It is a p-type semiconductor. It is a basic oxide and easily dissolved to dilute acids, and then almost colourless terbium salt is formed.
Their atmospheric concentrations and contribution to anthropogenic greenhouse gas emissions are rapidly increasing, causing international concern about their radiative forcing. Fluorocarbons with few C–F bonds behave similarly to the parent hydrocarbons, but their reactivity can be altered significantly. For example, both uracil and 5-fluorouracil are colourless, high-melting crystalline solids, but the latter is a potent anti-cancer drug. The use of the C-F bond in pharmaceuticals is predicated on this altered reactivity.
In contrast, the second year of mourning permitted grievers to wear more subdued colours such as white or colourless materials, pearls and diamonds. Wearing mourning jewellery displayed the strong connection between a beloved and the deceased person. For this reason, the Victorian mourning period saw the development of personalised jewellery that were used as momentos. Mourning jewellery often displayed initials or the names of the deceased and their date of death which were engraved into the jewellery in remembrance of the departed.
Upeneus pori has an elongated body and a rounded snout. The body is greyish or red-brown, darker on the back, and covered with grey or reddish brown spots which go as far as the lower flanks but with no or a very faint lateral stripe visible in freh specimens. There is a dark brown or red bar whicg runs vertically through the eye and the barbels located on the chin are white or yellow. The first dorsal fin is colourless.
The blood may be colourless, or have any of three different respiratory pigments. The most common of these is haemoglobin, but some groups have haemerythrin or the green-coloured chlorocruorin, instead. The nervous system consists of a single or double ventral nerve cord running the length of the body, with ganglia and a series of small nerves in each segment. The brain is relatively large, compared with that of other annelids, and lies in the upper part of the head.
This nudibranch reaches a maximum size of 14 mm, but commonly it is under 10 mm in adult size.Behrens, David W., 1980, Pacific Coast Nudibranchs: a guide to the opisthobranchs of the northeastern Pacific, Sea Challenger Books, Washington. The body is colourless, but the cerata are coloured due to the digestive glands inside them. The colour of the digestive gland can be creamy yellow to orange-red to brown, depending on the colour of the hydroids that an individual specimen has been eating.
The velvety cap is initially slightly convex (planoconvex), becoming funnel-shaped (infundibuliform) as it matures; it is 4–15 cm (1½–4 in) in diameter and has a faint zonate (bull's-eye) pattern, beige or light grey at the margins and darkening toward the centre. The decurrent gills are cream when young, and darkening to ochre-yellow with age. The flesh is white or beige, often pink- tinged. The latex, or milk, is watery and colourless, unlike that of any other milkcap.
EGTA (ethylene glycol-bis(β-aminoethyl ether)-N,N,N′,N′-tetraacetic acid), also known as egtazic acid (INN, USAN), is an aminopolycarboxylic acid, a chelating agent. It is a colourless solid that is related to the better known EDTA. Compared to EDTA, it has a lower affinity for magnesium, making it more selective for calcium ions. It is useful in buffer solutions that resemble the environment in living cells where calcium ions are usually at least a thousandfold less concentrated than magnesium.
The water of the lake is very clear and virtually colourless, which reflects the nutrient-poor flat rock pine forest of the surrounding area. Most of nutrient contribution to the lake comes from settlements south of the lake, also responsible for about 80 per cent of the phosphorus input. A hydrogeological examination in 1985 showed the surrounding soil is poorly fit to take up increased levels of waste water. Acidification has been neutralized by liming which has produced excellent pH- levels.
Fully stretched out specimens are usually between 500 and 1200 micrometres in length, but size is extremely variable. It is a colourless species, with no pigmentation in the cell cortex. The body of the organism is covered with 40-80 longitudinal rows of cilia, and the oral region is encircled by a long spiraling row of specialized ciliary structures called membranelles which are mainly used for brushing prey into the cell mouth (cytostome). The cytoplasm is transparent, and contains no symbiotic algae (zoochlorellae).
In 1977, Pennell began to engrave on glass, adapting gem engraving techniques to a larger scale. Initially working with commercially available glass vessels, he later transferred to working on vessel blanks, free-blown to his specification by the glass artist Carl Nordbruch. In addition to working on clear, colourless glass, Pennell broadened his approach to include cased, flashed and graal glasses. In 1979, he exhibited at the Corning Museum World Glass Exhibition and World Tour, which brought his work to international attention.
They lack hemoglobin in their blood, resulting in their blood being colourless. One Channichthyidae species, the mackerel icefish (Champsocephalus gunnari), was once the most common fish in coastal waters less than deep, but was overfished in the 1970s and 1980s. Schools of icefish spend the day at the seafloor and the night higher in the water column eating plankton and smaller fish. There are two species from the genus Dissostichus, the Antarctic toothfish (Dissostichus mawsoni) and the Patagonian toothfish (Dissostichus eleginoides).
Solutions of RhCl3(H2O)3 react with ammonia in the presence of alcohol to give the salt pentamminerhodium chloride, [RhCl(NH3)5]Cl2. Zinc reduction of this cation followed by the addition of sulfate gives the colourless hydride complex [HRh(NH3)5]SO4. Upon boiling in a mixture of ethanol and pyridine (py), hydrated rhodium trichloride converts to trans-[RhCl2(py)4)]Cl. In the absence of a reductant, the reaction affords fac-[RhCl3(py)3], analogous to the thioether derivatives.
In the solid state the dimeric form is not present; the 2-pyridones form a helical structure over hydrogen bonds. Some substituted 2-pyridones form the dimer in solid state, for example the 5-methyl-3-carbonitrile-2-pyridone. The determination of all these structures was done by X-ray crystallography. In the solid state the hydrogen is located closer to the oxygen so it could be considered to be right to call the colourless crystals in the flask 2-pyridone.
The leaf withers as the spots join together. Leaves then die and fall off [3]. In severe cases, only a few new leaves on the top of the plant are left [4]. More signs can be found under microscope [6]: Conidia can be taken from the black mats on lower leaf surface of infected leaves. These obclavate-cylindrical and slightly flexuous conidia have 4 to 9 septa, appearing as smooth, colourless to olivaceous brown, of size 35-155 × 4–4.5 μm.
Cyanogen azide, N3CN or CN4, is an azide compound of carbon and nitrogen which is an oily, colourless liquid at room temperature. It is a highly explosive chemical that is soluble in most organic solvents, and normally handled in dilute solution in this form. It was first synthesised by F.D. Marsh at DuPont in the early 1960s. Cyanogen azide is a primary explosive, although it is far too unstable for practical use as an explosive and is extremely dangerous outside dilute solution.
Diamond however is a highly transparent colourless cubic crystal with poor conductive properties, is the hardest known naturally occurring mineral and has the highest refractive index of all gemstones. In contrast to the crystal lattice structure of diamond and graphite, the fullerenes are molecules, named after Richard Buckminster Fuller whose architecture the molecules resemble. There are several different fullerenes, the most widely known being the "buckeyball" C60. Little is known about the fullerenes and they are a current subject of research.
Critical opinion was not kind to Agathocle. La Harpe described it as ‘a most imperfect sketch’ with lifeless and colourless characters which the author might have been able to work up into a full play if he had tackled the subject earlier before his strength failed him. The Kehl edition of Voltaire's works also emphasised that the work was little more than an outline, of value mainly because it showed how Voltaire worked up a dramatic idea into a final performance text.
Liquid nitrogen, a colourless fluid resembling water in appearance, but with 80.8% of the density (the density of liquid nitrogen at its boiling point is 0.808 g/mL), is a common cryogen. Solid nitrogen has many crystalline modifications. It forms a significant dynamic surface coverage on Pluto and outer moons of the Solar System such as Triton. Even at the low temperatures of solid nitrogen it is fairly volatile and can sublime to form an atmosphere, or condense back into nitrogen frost.
Note the small entrance to the trap underneath the swollen 'balloon', and the colourless patches that confuse prey trapped inside The cobra plant is not just restricted to nutrient-poor acidic bogs and seepage slopes, but many colonies actually thrive in ultramafic soils, which are in fact basic soils, within its range. In common with most carnivorous plants, the cobra lily is adapted to supplementing its nitrogen requirements through carnivory, which helps to compensate for the lack of available nitrogen in such habitats.
Hippocrates. The first classical text to mention the disease is Herodotus' Histories in which he relates how a Persian general, Pharnouches, abandoned Xerxes' campaign against the Spartans due to consumption. Hippocrates, in Book 1 of his Of the Epidemics, describes the characteristics of the disease: fever, colourless urine, cough resulting in a thick sputa, and loss of thirst and appetite. He notes that most of the sufferers became delirious before they succumbed to the disease.Hippocrates, Of the Epidemics 1.i.
Adyte hyalina is colourless or yellowish, up to thirty millimetres long, and has a dark band running down its back.John Barrett and C M Young, Collins Pocket Guide to the Sea Shore (1958) p.68 Adyte hyalina is a long-bodied scale-worm with up to about 70 segments and 15 pairs of elytra, leaving the long tail uncovered. The prostomium is rounded anteriorly (without peaks) and with three antennae; the lateral antennae are inserted ventrally to the median antenna.
At the sutures, and in the middle of the body whorl (in some specimens also on the upper whorls), there is a very pale ochraceous banding, the nodules of the ribs still retaining their white lustre. In other specimens the first three or four whorls remain quite colourless. The aperture is oblong. The sinus is sutural, oblquely extending over the outer lip, which is much incrassate within with seven prominent denticles, these being provided with three also of lesser size.
Nimrod is an unethical scientist who does not suffer fools gladly. He is cruel and sadistic, as seen in his treatment of the Huldan alien creature and of the Doctor clones he created during Project: Lazarus. He is bald and has almost completely colourless skin and lips, while his eyes are a vibrant blue. His cybernetic implants allow him to link to Oracle, the Forge's supercomputer, and also keep track of the vital signs of other Forge personnel in the vicinity.
Elemental bromine is very reactive and thus does not occur free in nature, but in colourless soluble crystalline mineral halide salts, analogous to table salt. While it is rather rare in the Earth's crust, the high solubility of the bromide ion (Br−) has caused its accumulation in the oceans. Commercially the element is easily extracted from brine pools, mostly in the United States, Israel and China. The mass of bromine in the oceans is about one three-hundredth that of chlorine.
In addition to the vertical axis the building also has a horizontal symmetry axis that goes diagonally through the building. The flat- roofed extension of the church, built after the 1938 fire, was constructed with red brick masonry which contrasts with the charred Queenston façade. Tall, thin arched windows cover the walls of the church, with the exception of the extension building whose windows are rectangular. The windows are divided into squares and diamonds of yellow and colourless textured glass.
Dithiobiuret is an organosulfur compound with the formula HN(C(S)NH2)2. It is a colourless solid that is soluble in warm water and polar organic solvents. It is a planar molecule with short C-S and C-N distances (1.69, 1.38 Å, resp.) indicative of multiple C-S and C-N bonding. The compound can be viewed as the product from the condensation of two molecules of thiourea, but it is prepared by treatment of 2-cyanoguanidine with hydrogen sulfide.
Bulliform cells or motor cells are large, bubble-shaped epidermal cells that occur in groups on the upper surface of the leaves of many monocots. These cells are present on the upper surface of the leaf. They are generally present near the mid-vein portion of the leaf and are large, empty and colourless. They are proposed, though not confirmed, to be involved in folding and unfolding of leaf tissue in order to control light intensity and reduce overall water loss.
Conidia have been found to disintegrate both in the air and on impact with an agar plate. Condiophores and conidia grow from hyphae sprouted outside of a trapped dead nematode, and condiophores have been found to change and grow into part of the adhesive net. Under ideal conditions, a colony can reach 65 mm in diameter after 7 days incubation, with colourless, pale pink or yellow mycelium. The optimal growth temperature for the fungus in nematode-free and nematode-infested environments is and , respectively.
Sage Derby is a variety of Derby cheese that is mild, mottled green and semi- hard, and has a sage flavour. The colour is from sage and sometimes other colouring added to the curds, producing a marbling effect and a subtle herb flavour. The colour is formed either by mixing sage leaves into the curd before it is pressed or by the addition of "green curd" from green corn or spinach juice. In the latter case, the flavour has to be created with colourless sage extract.
Asterolasia pallida is a woody, perennial herb that typically grows to a height of about and sometimes forms a rhizome. The leaves are elliptical, long and covered with star-shaped hairs on the lower side. The flowers are arranged in umbels of three to six in leaf axils and on the ends of branchlets, each flower on a thin pedicel long. The petals are white, elliptical, long, with rust-coloured and colourless, star-shaped hairs on the back, and there are fifteen to twenty-five stamens.
Cerebrospinal fluid circulates in spaces around and within the brain Cerebrospinal fluid is a clear, colourless transcellular fluid that circulates around the brain in the subarachnoid space, in the ventricular system, and in the central canal of the spinal cord. It also fills some gaps in the subarachnoid space, known as subarachnoid cisterns. The four ventricles, two lateral, a third, and a fourth ventricle, all contain a choroid plexus that produces cerebrospinal fluid. The third ventricle lies in the midline and is connected to the lateral ventricles.
The cis and trans isomers of MCHM. It is a colourless oil with a faint mint-like alcohol odor. The trans isomer has a particularly low odor threshold (~7 ppb in water) and a more licorice-like quality which is not associated with the less detectable cis isomer.A similar distinction has been reported in the closely related compound p-menthan-7-ol, where the cis isomer has a "fresh" lily-of-the-valley scent while the trans isomer has a "powerful cumin-like" odor.
Another particularly interesting kind of rust that affects the Clematis paniculata is Puccinia alboclava because It only affects the C. paniculata and no other kind of Clematis species. Puccinia alboclava is found in the soft leaves of the Clematis paniculata species seedling. It is only found to infect Clematis paniculata in Dunedin and the centre of the North Island The rust produces colourless teleutospore on the host. This is extremely rare kind of rust and appears to be the first to do this on a clematis species.
Cercophora areolata produces perithecia, also known as ascomata, which are fruiting bodies with necks. The perithecia of C. areolata are described as ovoid to conical, aggregated, non-stromatic, ostiolate (have small pores for the discharge of spores), and they have cone- shaped, ridged necks. Perithecia may be glabrous, enveloped with flexuous, brown, septate thick hairs or with short, hyaline (colourless), cylindrical, septate hairs. The perithecia are also characterized as superficial, in which the perithecia appear along the stalk, similar to the phenotype of the Ophiocordyceps species.
Catherine de' Medici, as Queen consort of France, 1550s. Portrait at the Uffizi Gallery. "Her mouth is too large and her eyes too prominent and colourless for beauty", wrote a Venetian envoy as Catherine approached forty, "but a very distinguished-looking woman, with a shapely figure, a beautiful skin and exquisitely shaped hands". Henry allowed Catherine almost no political influence as queen.Morris, 247 Although she sometimes acted as regent during his absences from France, her powers were strictly nominal.Knecht, Catherine de' Medici, 42–43.
Eggs are laid singly on either side of a leaf, near the margin, or on a petiole of bramble (Rubus fruticosus) and raspberry (Rubus idaeus). When hatching the larva are colourless and chew through the top of the egg, leaving the rest uneaten. They soon become green matching the colour of their foodplant and live on the upper side of a leaf under a slight web, occasionally moving to a fresh leaf. The pupa ia initially green and darkens with successive colour changes before becoming iridescent.
The stomach occupies most of the interior of the bell and there are a ring of small cream or white gonads round its edge. The colouration of this jellyfish varies, but in general, the bell is translucent and colourless or a pale shade of buff, sometimes with irregular streaks of light brown. The dangling lappets round the edge of the bell are darker brown and the lower parts of the oral tentacles may be brown as well, the upper parts being colourless.Lychnorhiza lucerna Marine Species Identification Portal.
The hypothecium (the layer of hyphal tissue immediately beneath the hymenium) is prosoplectenchymatous (a cell arrangement where the hyphae are all oriented in one direction), and translucent to dark brown. Asci are club- shaped, lacking a distinct tubular structure in the tholus that is characteristic of family Pilocarpaceae. Ascospores usually number 4 to 8 per ascus, and are colourless, ellipsoid, non-septate, and usually filled with oblong crystals. The spore walls are evenly thickened or thickened at the ends, and halonate (having a transparent outer layer).
Sodium triacetoxyborohydride, also known as sodium triacetoxyhydroborate, commonly abbreviated STAB, is a chemical compound with the formula Na(CH3COO)3BH. Like other borohydrides, it is used as a reducing agent in organic synthesis. This colourless salt is prepared by protonolysis of sodium borohydride with acetic acid:Gordon W. Gribble, Ahmed F. Abdel-Magid, "Sodium Triacetoxyborohydride" Encyclopedia of Reagents for Organic Synthesis, 2007, John Wiley & Sons. :NaBH4 \+ 3 HO2CCH3 → NaBH(O2CCH3)3 \+ 3 H2 Sodium triacetoxyborohydride is a milder reducing agent than sodium borohydride or even sodium cyanoborohydride.
Greenwood and Earnshaw, pp. 804–09 The colour fades at low temperatures, so that solid chlorine at −195 °C is almost colourless. Like solid bromine and iodine, solid chlorine crystallises in the orthorhombic crystal system, in a layered lattice of Cl2 molecules. The Cl–Cl distance is 198 pm (close to the gaseous Cl–Cl distance of 199 pm) and the Cl···Cl distance between molecules is 332 pm within a layer and 382 pm between layers (compare the van der Waals radius of chlorine, 180 pm).
Orchids in the genus Rhizanthella are mostly underground, perennial, sympodial, mycotrophic herbs with fleshy underground stems which produce new shoots at nodes where there are colourless leaf-like cataphylls. There are no roots and new tubers form at the end of short stems. The leaves are reduced to scale-like structures lacking chlorophyll, pressed against and sheathing the stems. The inflorescence is a head containing many flowers and is held at, or just above ground level but the head is usually covered with leaf litter or soil.
Lactarius helvus, commonly known as fenugreek milkcap, is a member of the large milkcap genus Lactarius in the order Russulales. Fruiting bodies can be found in Sphagnum moss in coniferous and deciduous woodland in Europe, and possibly North America, although considerable debate continues about the North American variety, formerly referred to as Lactarius aquifluus. Mushrooms are pale brown-grey or beige in colour and funnel-shaped, with colourless, watery milk. Its distinctive smell has been likened to fenugreek, celery, liquorice, or Maggi instant soup.
CSF circulates in the subarachnoid space (between arachnoid and pia mater). Cerebrospinal fluid is produced by the choroid plexus (inside the ventricles of the brain, which are in direct communication with the subarachnoid space so the CSF can flow freely through the nervous system). Cerebrospinal fluid is a transparent, colourless fluid and it is produced at about 500 ml/day. Its electrolyte levels, glucose levels, and pH are very similar to those in plasma, but the presence of blood in cerebrospinal fluid is always abnormal.
Anthraquinone Anthraquinone dyes are an abundant group of dyes comprising a anthraquinone unit as the shared structural element. Anthraquinone itself is colourless, but red to blue dyes are obtained by introducing electron donor groups such as hydroxy or amino groups in the 1-, 4-, 5- or 8-position. Anthraquinone dyestuffs are structurally related to indigo dyestuffs and are classified together with these in the group of carbonyl dyes. Members of this dye group can be found in natural dyes as well as in synthetic dyes.
Many esters are known, such as pentabenzoyls and pentaacetyls. Trteatment of the derivative 3,4,5-tri-O- acetyl-1,2-O-ethylidene-(1,2,4/3,5)-cyclopentanepentol with triphenylcarbenium tetrafluoroborate to yield the cation 3,4,5-tri-O- acetyl-(1,2,4/3,5)-cyclopentanepentol-1,2-O-acetoxonium, which exhibits a peculiar 10-stage cyclic rearrangement. Cyclopentanepentols form dihydrogenphosphate esters analogous to inositol's phytic acid esters. The related compound 1,2,3,4,5-pentakis(hydroxymethyl)-cyclopentane (a colourless viscous oil, soluble in tert-butanol and DMSO) was synthesized in 1985 by L. M. Tolbert and others.
Barium metaphosphate is an inorganic substance with the molecular formula Ba(PO3)2. It is a colourless solid that is insoluble in water, though is soluble in acidic solutions through "slow dissolution". X-ray crystallography shows that this material is composed of Ba2+ cations attached to a polyphosphate ((PO3−)n) anion."Form of barium metaphosphate" Grenier, Jean C.; Martin, Claude M.; Durif, Andre; Tran Qui Duc; Guitel, J.

It is colourless but the animal appears green because of the blood corpuscles circulating in blood vessels within the mantle. The arrangement of muscles in the mantle is important for distinguishing Perophora viridis from other species. These muscles are limited to about twelve muscles running longitudinally from the siphonal plate, a slightly depressed area between the siphons. The muscles extend for about a quarter of the length of the zooid and their function is to enable the animal to contract and protect its siphons.
Several critics complained the title made the book sound as if the main character is a nun. The title of the book was considered by The Newark Sunday News to be the "weakest thing about the book" because it "does not bear the faintest relation to the story." Similarly, Frederic Taber Cooper in The Bookman declared it to be a "colourless and misleading title". Other common complaints were about the length of the book and that it is so depressing that it is unpleasant to read.
The Briolette of India is a colorless diamond (weighing ) that was found in India. It is cut in a briolette shape, and is a D-coloured (colourless) type IIa diamond. Its history was thought to date from the 12th century, when it was first acquired by Eleanor of Aquitaine, the Queen consort of King Louis VII of France between 1137 and 1152. This makes the Briolette of India the oldest diamond on record in the world, even older than the famous Koh-i-Noor.
Ammonia is a compound of nitrogen and hydrogen with the formula NH3. A stable binary hydride, and the simplest pnictogen hydride, ammonia is a colourless gas with a characteristic pungent smell. It is a common nitrogenous waste, particularly among aquatic organisms, and it contributes significantly to the nutritional needs of terrestrial organisms by serving as a precursor to food and fertilizers. Ammonia, either directly or indirectly, is also a building block for the synthesis of many pharmaceutical products and is used in many commercial cleaning products.
Five Dynasties period The white body of Xing ware may be thinly potted, and fine enough to not require the application of a slip to hide any imperfection or coarseness. The coarser type of Xing ware, however, may have a layer of white slip. The body is usually covered with a thin colourless glaze, but often the glazes of Xing ware have a bluish tinge. The glaze contained magnesium oxide and phosphorus pentoxide, which reduce glaze dripping and cracking and giving it a whiter and smoother appearance.
B. fasciolatus and B. tigrinus are the only Batasio species in which the adult colouration consists of five or six vertical dark brown bars on a light brown body. B. tengana has bands descending from the dorsal surface to the lateral line. B. travancoria has a lateral stripe along the lateral line and a faint shoulder spot. B. sharavatiensis is the only Batasio that has a completely plain and colourless body; its adipose fin is almost confluent (continuous) with the caudal fin save for a small notch.
The Arsenic Act 1851 (14 & 15 Vict c. 13) was passed by the United Kingdom Parliament in 1851, during the reign of Queen Victoria. Arsenic was at the time widely used as a pigment and in agricultural products such as sheep dressings; the Act was introduced to address increasing public concern over accidental and deliberate arsenic poisonings. The definition of arsenic for the purposes of the Act included "Arsenious Acid and the Arsenites, Arsenic Acid and the Arseniates, and all other colourless poisonous Preparations of Arsenic".
Experimenting with the new technology, the forest glassmakers found it difficult to achieve the high standards of clarity and colour of the Roman methods, due mainly to the great variability of colour- controlling elements in the raw materials. European sand and soil is generally higher in iron and manganese. Iron gives a blue-green tinge to glass under usual furnace atmosphere conditions, but also may give a yellow colour. Manganese has its own purple colour which may balance out the iron colour to make colourless glass.
From the central sinus in the collar, blood flows to a complex series of sinuses and peritoneal folds in the proboscis. This set of structures is referred to as a glomerulus and may have an excretory function, since acorn worms otherwise have no defined excretory system. From the proboscis, blood flows into a single blood vessel running underneath the digestive tract, from which smaller sinuses supply blood to the trunk, and back into the dorsal vessel. The blood of acorn worms is colourless and acellular.
Lighting at the CN Tower and the 3D Toronto sign at Nathan Phillips Square were colourless and dimmed for the evening of April 23. Flags were placed at half- mast at most government locations in Toronto and surrounding municipalities. An impromptu memorial at Olive Square Park on the east side of Yonge Street, directly across the street from where the attack began, was started by a local resident at 5:15 p.m. of the same day for people to place flowers and express their grief in writing.
Electro-galvanic fuel cell as used in a diving rebreather Gas mixtures must generally be analysed either in process or after blending for quality control. This is particularly important for breathing gas mixtures where errors can affect the health and safety of the end user. It is difficult to detect most gases that are likely to be present in diving cylinders because they are colourless, odourless and tasteless. Electronic sensors exist for some gases, such as oxygen analysers, helium analyser, carbon monoxide detectors and carbon dioxide detectors.
Quetzal are half-bird, half-human beings living in The Quetzal Forest. They have wings as well as arms, and beaks instead of mouths, and come in a variety of colours. They hatch from brightly coloured eggs in treetop nests, and although colourless eggs are sometimes laid, they are considered by the mothers to be unlucky and are rolled out of the nest. Quetzal naturally flock together in groups, and all quetzal share access to a collective Memoryplace, to which every quetzal can add.
The ciliary body is triangular in horizontal section and is coated by a double layer, the ciliary epithelium. The inner layer is transparent and covers the vitreous body, and is continuous from the neural tissue of the retina. The outer layer is highly pigmented, continuous with the retinal pigment epithelium, and constitutes the cells of the dilator muscle. The vitreous is the transparent, colourless, gelatinous mass that fills the space between the lens of the eye and the retina lining the back of the eye.
According to experiments with rodents, batrachotoxin is one of the most potent alkaloids known: its subcutaneous in mice is 2 µg/kg. Meanwhile, its derivative, batrachotoxinin A, has a much lower toxicity with an of 1000 µg/kg. The toxin is released through colourless or milky secretions from glands located on the back and behind the ears of frogs from the genus Phyllobates. When one of these frogs is agitated, feels threatened or is in pain, the toxin is reflexively released through several canals.
The Namib brush-tailed gerbil is the largest species in the genus Gerbillurus, growing to a head-and-body length of about with a tail of around . The dorsal fur is a pale sandy brown colour, individual hairs having a grey basal half and a sandy tip. The flanks are paler than the back, and the face, chin, throat and underparts are white. The eyes are surrounded by indistinct whitish eye rings, the ears are colourless and scantily furred, and the whiskers are black and white.
Krytox fluoroether-based grease (left) is often used in laboratories, including in high-vacuum applications, due to its inertness. Pictured alongside a tube of Dow Corning silicone grease (green), also used in high- vacuum applications. Krytox is a registered trademark of The Chemours Company. It refers to a group of colourless synthetic lubricants (oils and greases) with a variety of applications.Günter Siegemund, Werner Schwertfeger, Andrew Feiring, Bruce Smart, Fred Behr, Herward Vogel, Blaine McKusick “Fluorine Compounds, Organic” Ullmann's Encyclopedia of Industrial Chemistry, Wiley-VCH, Weinheim, 2002.
Chiropsalmus quadrumanus is a cube-shaped, colourless, transparent jellyfish with a diameter of about and height a little less than this. The body is composed of a gelatinous material and the top edges are rounded while the top surface is flat. Bundles of 7 to 9 tentacles dangle from pedalia, palmate appendages at the four lower corners of the bell, with a tentacle on each "finger". The outer two tentacles are pinkish and the inner ones yellowish white and they can be up to long.
The polyp is translucent and the colour is variable and may be white, pink, orange, red, brown or bright green. Sometimes there are contrasting regions of colour, especially forming a zig- zag pattern round the mouth. The tentacles are colourless except for the white or brown terminal knobs and the many tiny warts. A form found in deep water is smaller and more delicate; it has an inverse cone shape which is narrowed at the base, while shallow water forms are cylindrical and more robust.
The ascospores, which number eight per ascus, are simple, ellipsoid, colourless, and measure 5–8 by 8–14 μm. The upper cortex contains the lichen acids atranorin, chloroatranorin, and secalonic acid. The medulla contains hopane triterpene compounds such as zeorin and leucotylic acid as well as secalonic acid A. The presence of these triterpenes distinguishes this genus from Parmelina, and its segregate genera, including Parmelinella, and Parmelinopsis. secalonic acid A is a yellow pigment that reacts C+ yellow and K+ yellow with lichen spot tests.
The film drew heavily on the ideas of Jan Kott, in particular his observation that King Lear was the precursor of absurdist theatre: in particular, the film has parallels with Beckett's Endgame.Brode pp.206–207. Critics who dislike the film particularly draw attention to its bleak nature from its opening: complaining that the world of the play does not deteriorate with Lear's suffering, but commences dark, colourless and wintry, leaving (in Douglas Brode's words) "Lear, the land, and us with nowhere to go".Brode pp.
In laboratory, solutions containing crystal violet and formalin are often used to simultaneously fix and stain cells grown in tissue culture to preserve them and make them easily visible, since most cells are colourless. It is also sometimes used as a cheap way to put identification markings on laboratory mice; since many strains of lab mice are albino, the purple colour stays on their fur for several weeks. In body piercing, gentian violet is commonly used to mark the location for placing piercings, including surface piercings.
Spirorbis corallinae is a very small (1-2 mm) coiled polychaete that lives attached to seaweed in shallow saltwater. It has a smooth, white or semi- translucent, sinistral (left-handed) coiled shell encasing an orange body about 1.5 mm in length. The worm has a short abdominal region and a slightly broader thorax terminating in colourless tentacles, used to filter food from the water. One of the tentacles is slightly larger than the rest and shaped like a saucer, which is used as an operculum.
Polyaniline was first described in the mid-19th century by Henry Letheby, who investigated the electrochemical and chemical oxidation products of aniline in acidic media. He noted that reduced form was colourless but the oxidized forms were deep blue. The first highly-conductive organic compounds were the charge transfer complexes. In the 1950s, researchers reported that polycyclic aromatic compounds formed semi-conducting charge-transfer complex salts with halogens. In 1954, researchers at Bell Labs and elsewhere reported organic charge transfer complexes with resistivities as low as 8 ohms-cm.
His reputation continued to increase during this period, which stood him in good stead to take the position of Chief Justice at Calcutta, Bombay or Madras.The Lawyer, vol. 2, 1970, pg 90 With no opening at Calcutta or Bombay, Morgan was appointed Chief Justice of the Madras High Court, where he remained until 7 February 1879. Although Morgan was respected during his time at Madras, he was not a loved figure to either the Bar or the public; some were critical of him, and he was perceived as 'chill' and 'colourless'.
A product comprising more repeating units (n = 2 to 30) is at room temperature a colourless solid, which is correspondingly referred to as solid epoxy resin. Instead of bisphenol A, other bisphenols (especially bisphenol F) or brominated bisphenols (e. g. tetrabromobisphenol A) can be used for the said epoxidation and prepolymerisation. Bisphenol F may undergo epoxy resin formation in a similar fashion to bisphenol A. These resins typically have lower viscosity and a higher mean epoxy content per gram than bisphenol A resins, which (once cured) gives them increased chemical resistance.
Omnivorous animal species which are relatively poor converters of coloured dietary carotenoids to colourless retinoids have yellowed-coloured body fat, as a result of the carotenoid retention from the vegetable portion of their diet. The typical yellow- coloured fat of humans and chickens is a result of fat storage of carotenes from their diets. Carotenes contribute to photosynthesis by transmitting the light energy they absorb to chlorophyll. They also protect plant tissues by helping to absorb the energy from singlet oxygen, an excited form of the oxygen molecule O2 which is formed during photosynthesis.
Yellowed thorium dioxide lens (left), a similar lens partially de-yellowed with ultraviolet radiation (centre), and lens without yellowing (right) When added to glass, thorium dioxide helps increase its refractive index and decrease dispersion. Such glass finds application in high-quality lenses for cameras and scientific instruments. The radiation from these lenses can darken them and turn them yellow over a period of years and degrade film, but the health risks are minimal. Yellowed lenses may be restored to their original colourless state by lengthy exposure to intense ultraviolet radiation.
Although some species lack a blood vascular system, where it is present, it resembles that of other annelids. The blood is essentially colourless, although some haemoglobin-containing cells are present in the coelomic fluid of the main body cavity. There can be anywhere from one to over a hundred metanephridia for excreting nitrogenous waste, which typically open near the anterior end of the animal. The nervous system consists of a brain near the base of the proboscis, and a ventral nerve cord running the length of the body.
835–42 Some pseudohalides of chlorine are also known, such as cyanogen chloride (ClCN, linear), chlorine cyanate (ClNCO), chlorine thiocyanate (ClSCN, unlike its oxygen counterpart), and chlorine azide (ClN3). Chlorine monofluoride (ClF) is extremely thermally stable, and is sold commercially in 500-gram steel lecture bottles. It is a colourless gas that melts at −155.6 °C and boils at −100.1 °C. It may be produced by the direction of its elements at 225 °C, though it must then be separated and purified from chlorine trifluoride and its reactants.
Triphenylphosphite forms zero-valent complexes of the type M[P(OC6H5)3]4 for M = Ni, Pd, Pt. The colourless nickel complex (melting point 147 °C) can be prepared from the nickel(0) complex of cycloocta-1,5-diene:Ittel, S. D. "Olefin, Acetylene, Phosphine, Isocyanide, and Diazene Complexes of Nickel(0)" Inorganic Syntheses, 1977, volume XVII, p. 117–124. : Ni(COD)2 \+ 4 P(OC6H5)3 → Ni[P(OC6H5)3]4 \+ 2 COD It also forms a variety of Fe(0) and Fe(II) complexes such as the dihydride H2Fe[P(OC6H5)3]4.
There is a rounded protuberance on the forehead, the sphenotic spines (above the eyes) are large in young specimens but become overgrown with skin in older ones, and there is a symphysial spine at the tip of the jaw. The caudal peduncle is particularly short. The head and body are dark reddish-brown, or completely black, and the fins are usually colourless. The dorsal fin and the anal fin both have three soft rays, while the pectoral fins have fifteen to eighteen rays each, and the caudal fin has nine.
Symbiotic bacteria belonging to the family Vibrionaceae are responsible for the luminescence; the strain of bacteria is apparently different in each species. The bacteria are believed to originate from the surrounding seawater and colonise the organs via external ducts. The light produced is bluish to greenish, and the host female presumably has some control over its production. Like other deep-sea anglers, leftvents have watery flesh and poorly ossified bones; the skin, which in females is a dark brown to black in life (but colourless in Haplophryne), is extremely fragile and abrades with ease.
Rice vinegar is a very mild and mellow vinegar and ranges in colour from colourless to pale yellow. There are two distinct types of Japanese vinegar: one is made from fermented rice and the other, known as awasezu or seasoned rice vinegar is made by adding sake, salt and sugar. Seasoned rice vinegar is used in sushi and in salad dressing varieties popular in the west, such as ginger or sesame dressing. Rice vinegar can be mixed with salt and sugar to make sushi vinegar, which is used to season the rice used in sushi.
Acetaldehyde ammonia trimer is a chemical compound described by the formula (CH3CHNH)3. The pure material is colourless but samples often appear light yellow or slightly beige due to the degradation by oxidation. It is hygroscopic, and can be found in a trihydrate form. As implied by its name, it is a trimeric species formed from the reaction of acetaldehyde and ammonia: : 3 CH3CHO + 3 NH3 → (CH3CHNH)3 \+ 3 H2O Studies using NMR spectroscopy indicate that the three methyl groups are equatorial, thus the molecule has C3v point group symmetry.
Asci (spore-bearing cells) are more or less club-shaped, and contain eight spores. They are surrounded by a thin outer amyloid wall layer and a thicker, non-amyloid inner wall layer; a non-amyloid zone rests above the axial body of the ascus. The ascospores are colourless, lack septa, and have smooth walls with occasional thickening at either end. The spores have a range of shapes; depending on the species, the following shapes have been recorded: ellipsoid, ovoid (egg-shaped), fusiform (spindle-shaped), lemon- shaped, falciform (sickle-shaped), fabiform (bean-shaped), and partly curved.
In Calyptratae which includes the most advanced Diptera, the halteres are protected by calyptrae (small membranes above the halteres). The mesothoracic wing is entirely membranous, completely transparent and colourless, or bearing zonal pigmentation useful for recognition. Its surface is divided into three regions: the most developed is the alar (main flight) region, supported by robust wing veins; posteriorly is the anal region; and, finally, in the rear section-proximal, there is an expanded lobiform alula. The alula also termed the axillary lobe is a broad lobe at the proximal posterior margin of the wing stalk.
The De Beers Centenary Diamond is, at , the third-largest diamond to have been produced in the Premier Mine. Among top-color diamonds, only the Cullinan I and II are larger than the Centenary diamond. The Centenary Diamond is rated in color as grade D color by the Gemological Institute of America, which is the highest grade of colourless diamond and is internally and externally flawless. It was named the Centenary Diamond as it was presented in the rough for the Centennial Celebration of De Beers Consolidated Mines on 11 May 1988.
Other distinguishing features of the order are the presence of protrusible eyes, another adaptation to living on the seabed (benthos), and the extension of the dorsal fin onto the head. The surface of the fish facing away from the sea floor is pigmented, often serving to camouflage the fish, but sometimes with striking coloured patterns. Some flatfishes are also able to change their pigmentation to match the background, in a manner similar to some cephalopods. The side of the body without the eyes, facing the seabed, is usually colourless or very pale.
The prostomium, the first body segment (which cannot be seen from above) and the second segment are colourless, the third and fourth segments are dark, and the fifth and remaining segments have dark spots centred on the overlap of the segments, as well as some dark colour at the side of the segments. The posterior of the prostomium has some yellow colouring, and there are yellow spots between the dark spots on the dorsal surface of the body. This worm can have as many as 250 segments and be up to long.
A Charentais-style alembic cognac pot still After the grapes are pressed, the juice is left to ferment for 2–3 weeks, with the region's native, wild yeasts converting the sugar into alcohol; neither sugar nor sulfur may be added. At this point, the resulting wine is about 7 to 8% alcohol. Distillation takes place in traditionally shaped Charentais copper alembic stills, the design and dimensions of which are also legally controlled. Two distillations must be carried out; the resulting eau de vie is a colourless spirit of about 70% alcohol.
Neumann was advocate of the Unitarien Point of View: All blood cells shall be descended from this post embryonic stem cell. As it is well known, a quarrel broke out between dualists and unitarians (Paul Ehrlich). Neumann's farsightedness demanded a stem cell culture for the completion of the quarrel: "Perhaps a final decision will only arrive, if it possible, to isolate the individual colourless cells and to study its life events in vitro culture for some time, as Robert Koch demonstrated with the bacteria" (Neumann 1912, B.P., p. 329).
From January to August 1804, Ryan was editor and publisher of the New Brunswick Chronical,Collections of the New Brunswick Historical Society, Volumes 1-3, The Society, Daily Telegraph Steam Book and Job Print: Saint John, NB, 1894. Pg 78 described as, "This rather colourless newspaper was the first attempt of a young man in the publishing business. It carried a small amount of local news, foreign news copied from English papers, some dull literary articles, and a few poems mostly extracted from other newspapers."Harper, J. Russel (1961).
German Bartmann jug, c. 1600 Salt glazed containers Salt-glaze or salt glaze pottery is pottery, usually stoneware, with a glaze of glossy, translucent and slightly orange-peel-like texture which was formed by throwing common salt into the kiln during the higher temperature part of the firing process. Sodium from the salt reacts with silica in the clay body to form a glassy coating of sodium silicate. The glaze may be colourless or may be coloured various shades of brown (from iron oxide), blue (from cobalt oxide), or purple (from manganese oxide).
Because of its ability to be grown on agar plates into even, well coloured lawns, and the existence of a phage specific to S. marscecens, it has been used to trace water flows in Karst limestone systems. Known quantities of phage are injected into a fixed point in the Karst water system and the outflow of interest are monitored by conventional small-volume sampling at fixed time intervals. In the laboratory, the samples are poured onto grown S. marscecens lawns and incubated. Colourless plaques in the lawns indicate the presence of phage.
The party's future seemed bright, but it suffered from a number of weaknesses, not the least of which was its dependence on Gysi, considered by supporters and critics alike as a super-star in German politics who stood in stark contrast to a colourless general membership. Gysi's resignation in 2000 after losing a policy debate with party leftists soon spelled trouble for the PDS. In the 2002 federal election, the party's vote sank back to 4.0%, and was able to seat only two back-benchers elected directly from their districts, Petra Pau and Gesine Lötzsch.
All four of these isomers are gases at room temperature and pressure, but can be liquefied by lowering the temperature or raising the pressure on them, in a manner similar to pressurised butane. These gases are colourless, but do have distinct odours, and are highly flammable. Although not naturally present in petroleum in high percentages, they can be produced from petrochemicals or by catalytic cracking of petroleum. Although they are stable compounds, the carbon-carbon double bonds make them more reactive than similar alkanes, which are more inert compounds in various ways.
217–19 She undertook several studio recording sessions, including a series of Bach and Handel arias with Sir Adrian Boult and the London Philharmonic Orchestra in October.Campion, pp. 97–98 In November, after a Royal Festival Hall recital, she was distressed by a review in which Neville Cardus criticised her performance for introducing "distracting extra vocal appeals" designed to please the audience at the expense of the songs. However, she accepted his comments with good grace, remarking that "... it's hard to please everybody—for years I've been criticised for being a colourless, monotonous singer".
In April of that year the DC07, a new upright vacuum cleaner using "Root Cyclone" technology with seven cyclone funnels instead of the original dual-cyclone design, was launched. By 2009 Dyson began creating other technologies: the AirBlade hand dryer, the Air Multiplier "bladeless" fan and Dyson Hot, the "bladeless" fan heater. In October 2019, Dyson released the Pure Cryptomic, available in a fan version and a heater + fan version. The device is able to remove formaldehyde from the air; this flammable and colourless gas can irritate the skin, eyes, nose, and throat.
V&A;: The River Teme at Downton, Herefordshire On sculpture – typically for him, colourless form – generates in the mind the idea of shape which we must conceptualise, as with 'proportion'. The literary arts, like sculpture, deal with thoughts and emotions, though in a more complex form. Knight's account of these arts therefore falls under the heading of 'association of ideas'. Here Knight shows the influence of the contemporary cult of sensibility, arguing that these arts engage our sympathies, and in so doing demonstrate the inadequacy of 'rules and systems' in both morality and aesthetics.
According to his later report (Braid, 1817), at 7:00am on 1 March 1817, the mine's surgeon, James Braid, was called urgently to the mine to alleviate the distress of a number of miners who appeared to be suffocated. It was later established that noxious fumes from the faulty chimney of a coal- fired steam engine,This was partly a quality control failure. High sulphur content coal should never be used underground. Sulphur, when heated, is converted into sulphurous acid (H2SO3): a colourless, irritating gas, with the peculiar suffocating odour of burning brimstone.
Soldiers are larger and range in size from 5mm to 5.5mm in length and have larger heads that are yellow or red in colour. A large part of the head is taken up by a frontal gland that excretes a colourless, sticky fluid that has a strong irritant effect on other insects. There tends to be one soldier for every twenty to thirty workers relaying on workers to feed them. White nymphs emerge from mature mounds older than two or three years old in late autumn (April or May) after the first autumn rains.
All these regions have erect hairs. The anterior portions of both the petiole and postpetiole have appressed pubescence that is also seen on the propodeum. The colour of the queen is similar to that of a worker: the gaster is dark brown and the legs, scapes, and thorax are light brown with dark streaks on the mesoscutum. The head is yellowish or yellowish-brown around the central regions, the occiput and mandibles are a similar colour to the thorax, and the wing veins range from colourless to pale brown.
4-Dimethylaminopyridine (DMAP) is a derivative of pyridine with the chemical formula (CH3)2NC5H4N. This colourless solid is of interest because it is more basic than pyridine, owing to the resonance stabilisation from the NMe2 substituent. Because of its basicity, DMAP is a useful nucleophilic catalyst for a variety of reactions such as esterifications with anhydrides, the Baylis-Hillman reaction, hydrosilylations, tritylation, the Steglich rearrangement, Staudinger synthesis of β-lactams and many more. Chiral DMAP analogues are used in kinetic resolution experiments of mainly secondary alcohols and Evans auxiliary type amides.
In addition to its use in the H&E; stain, haematoxylin is also a component of the Papanicolaou stain (or PAP stain) which is widely used in the study of cytology specimens. Although the stain is commonly called haematoxylin, the active colourant is the oxidized form haematein, which forms strongly coloured complexes with certain metal ions (commonly Fe(III) and Al(III) salts). In its pure form, haematoxylin is a colourless and crystalline solid, although commercial samples are typically light to dark-brown based on the level of impurities present.
The former and stabiliser components of glass occur in all regions as sand or quartz and as lime of various forms. The northern Europeans experimented with using ash from wood, ferns, and bracken as a source of the alkali flux.Wedepohl 2005 At its height the Roman glass industry was producing high quality, thin, colourless, and clear glass of consistent composition. The earlier surviving Forest glass vessels are characterised by a wide variety of compositions and lower quality, often being greenish to brownish in colour, thick-walled, and with inclusions and bubbles in the fabric.
He wrote of the alkaloid's "colourless transparent prisms" and said that "Its solutions have an alkaline reaction, a bitter taste, promote the flow of saliva and leave a peculiar numbness, followed by a sense of cold when applied to the tongue." Niemann named the alkaloid "cocaine" from "coca" (from Quechua "kuka") + suffix "ine". Because of its use as a local anesthetic, a suffix "-caine" was later extracted and used to form names of synthetic local anesthetics. The first synthesis and elucidation of the structure of the cocaine molecule was by Richard Willstätter in 1898.
Etomidate is usually presented as a clear colourless solution for injection containing 2 mg/ml of etomidate in an aqueous solution of 35% propylene glycol, although a lipid emulsion preparation (of equivalent strength) has also been introduced. Etomidate was originally formulated as a racemic mixture,International Non-Proprietary Names for Pharmaceutical Preparations – Rec. I.N.N. List 6 but the R form is substantially more active than its enantiomer. It was later reformulated as a single-enantiomer drug, becoming the first general anesthetic in that class to be used clinically.
It occurs in shady places such as deciduous woodland and hedge sides. The plant consists of a branched whitish underground stem closely covered with thick, fleshy, colourless leaves, which are bent over so as to hide under the surface. The only portions that appear above ground in April to May are the short flower- bearing shoots, which bear a spike of two-lipped dull purple flowers, but is also able to produce cleistogamic underground flowers which fertilise themselves. It is also able to regenerate from broken fragments of the underground stem.
Lead(II) nitrate is an inorganic compound with the chemical formula Pb(NO3)2. It commonly occurs as a colourless crystal or white powder and, unlike most other lead(II) salts, is soluble in water. Known since the Middle Ages by the name plumb dulcis, the production of lead(II) nitrate from either metallic lead or lead oxide in nitric acid was small-scale, for direct use in making other lead compounds. In the nineteenth century lead(II) nitrate began to be produced commercially in Europe and the United States.
Carbon tetrachloride, also known by many other names (such as tetrachloromethane, also recognised by the IUPAC, carbon tet in the cleaning industry, Halon-104 in firefighting, and Refrigerant-10 in HVACR) is an organic compound with the chemical formula CCl4. It is a colourless liquid with a "sweet" smell that can be detected at low levels. It has practically no flammability at lower temperatures. It was formerly widely used in fire extinguishers, as a precursor to refrigerants and as a cleaning agent, but has since been phased out because of toxicity and safety concerns.
The lake is recharged mostly via surface flow from the Dalyup River directly into Lake Gore with Coobidge Creek supplying many of the surrounding lake systems. The maximum depth of Lake Gore is recorded as in 1986 when the lake was inundated but with a mean depth of and the lake has dried up several times the last being in 1984. The water is colourless and has low tannin levels. The salinity of the river varies depending on rainfall, the minimum salinity is recorded as 6.5ppt but the September mean is 52ppt.
The use of coloured glass as a decorative addition to pale and colourless glasses also increased, and metal vessels continued to influence the shape of glass vessels. After the conversion of Constantine, glass works began to move more quickly from depicting Pagan religious imagery towards Christian religious imagery. The movement of the capital to Constantinople rejuvenated the Eastern glass industry, and the presence of the Roman military in the western provinces did much to prevent any downturn there. By the mid-4th century mould-blowing was in use only sporadically.
Soluble thallium salts are added to gold plating baths to increase the speed of plating and to reduce grain size within the gold layer. A saturated solution of equal parts of thallium(I) formate (Tl(CHO2)) and thallium(I) malonate (Tl(C3H3O4)) in water is known as Clerici solution. It is a mobile, odorless liquid which changes from yellowish to colourless upon reducing the concentration of the thallium salts. With a density of 4.25 g/cm3 at 20 °C, Clerici solution is one of the heaviest aqueous solutions known.
Newland was born in Port Harcourt, Nigeria. Prior to becoming editor of The Daily Telegraph, he worked at the Catholic Herald from 1986 to 1989; then became a reporter and home editor on The Daily Telegraph (1989–98). He was deputy editor on the National Post, a conservative Canadian daily founded in 1998 by Lord Black of Crossharbour. Under Newland's news direction, the upstart daily found a distinctive voice and quickly came to within striking distance of the venerable, but colourless The Globe and Mail, before mounting losses forced major cutbacks in editorial staffing levels.
The first postage stamps of the state were issued for Princely State of Junagadh in 1864. They consisted of three lines of Hindi script in colourless letters on black, and were produced by hand-stamping with watercolor ink. A second issue in 1868 used coloured letters, printed in black or red on several colours of paper. The issue of 1877 was the first to include Latin letters; the circular design included the inscription "SORUTH POSTAGE" at the top, and "ONE ANNA OF A RUPEE" (or "FOUR ANNAS...") at the bottom.
Johannes Gijsbrecht Kuenen (born 9 December 1940, Heemstede) is a Dutch microbiologist who is professor emeritus at the Delft University of Technology and a visiting scientist at the University of Southern California. His research is influenced by, and a contribution to, the scientific tradition of the Delft School of Microbiology. Kuenen studied at the University of Groningen, where he received both his Doctorandus degree and in 1972 his Doctorate (PhD) under the supervision of Professor Dr. Hans Veldkamp. The title of his thesis was ‘‘Colourless sulphur bacteria from Dutch tidal mudflats’’.
Yellowed thorium dioxide lens (left), a similar lens partially de-yellowed with ultraviolet radiation (centre), and lens without yellowing (right) When added to glass, thorium dioxide helps increase its refractive index and decrease dispersion. Such glass finds application in high-quality lenses for cameras and scientific instruments. The radiation from these lenses can darken them and turn them yellow over a period of years and it degrades film, but the health risks are minimal. Yellowed lenses may be restored to their original colourless state by lengthy exposure to intense ultraviolet radiation.
Higher sulfur oxides are a group of chemical compounds with the formula SO3+x where x lies between 0 and 1. They contain peroxo (O−O) groups, and the oxidation state of sulfur is +6 as in SO3. Monomeric SO4 can be isolated at low temperatures (below 78 K) following the reaction of SO3 and atomic oxygen or photolysis of SO3–ozone mixtures. The favoured structure is: sulfur tetroxide Colourless polymeric condensates are formed in the reaction of gaseous SO3 or SO2 with O2 in a silent electric discharge.
In culture, colonies of P. obovatum begin as white or off-white in colour becoming pale green and centrally darkened with age. The green pigments diffuse into the growth medium ultimately becoming blackish-green in colour. Although the hyphae of the fungus are typically colourless (hyaline), the presence of these dark diffusible pigments has resulted in this species being considered one of the dematiaceous (aka filamentous, darkly-pigmented) fungi. This placement may be further justified by the confirmation of melanin pigments in hyphal walls and septa as demonstrated by Fontana-Masson's staining procedure.
Tuataric acid is an organic compound and an unsaturated carboxylic acid. This colourless compound was isolated in 2009 from the cloacal glands of the tuatara, a lizard-like reptile native to New Zealand. Its formal name is (4E,6Z)-octa-4,6-dienoic acid, and it consists of an unusual pair of conjugated alkene units with the E and Z configurations. Tuataric acid can be prepared from pent-4-yn-1-ol through a sequence that begins with the extension of the alkyne terminus by hydroboration and ends with the oxidation of the alcohol.
One of the most acutely toxic indoor air contaminants is carbon monoxide (CO), a colourless and odourless gas that is a by-product of incomplete combustion. Common sources of carbon monoxide are tobacco smoke, space heaters using fossil fuels, defective central heating furnaces and automobile exhaust. By depriving the brain of oxygen, high levels of carbon monoxide can lead to nausea, unconsciousness and death. According to the American Conference of Governmental Industrial Hygienists (ACGIH), the time-weighted average (TWA) limit for carbon monoxide (630–08–0) is 25 ppm.
The silicon-to-hydrogen bond is longer than the C–H bond (148 compared to 105 pm) and weaker (299 compared to 338 kJ/mol). Hydrogen is more electronegative than silicon (hence the naming convention of silyl hydrides), which results in the polarization of the Si-H bond to be the reverse of that for the C-H bond. Generally silyl hydrides are colourless with physical properties (solubility, volatility) comparable to hydrocarbons. They can be pyrophoric, reflecting the great driving force for replacing Si-H bonds with Si-O bonds.
At first, the stamps consisted of colourless (also known as albino) designs embossed directly onto a document using a die. Coloured ink in the embossed designs was introduced in the 1850s; initially this was pink but it was changed to vermilion in the 1870s. Blue ink was used for duplicate stamps. In the case of thick parchment such as vellum which did not allow for embossing directly on it, a paper was attached to the document using glue and a strip of tin, and the embossing was applied to this paper.
Marasmius sasicola produces colourless, ellipsoid basidiospores of between 8 and 10 by 4 to 6 micrometres (μm). The spores have no ornamentation, are not amyloid and have thin cell walls. In his examinations, Takahashi did not observe any basidia, but he did describe the club-shaped basidioles (immature basidia) which measured from 18 to 26 by 6 to 10 μm. The tightly packed cheilocystidia (cystidia on the edge of the gill) form a sterile edge to the gill, and there are no pleurocystidia (cystidia on the face of the gill).
In the yellow form, all three nitrogen atoms carry a positive charge, of which two are protonated, while the green colour corresponds to a form of the dye with two of the nitrogen atoms positively charged. At neutral pH, both extra protons are lost to the solution, leaving only one of the nitrogen atoms positive charged. The pKa for the loss of the two protons are approximately 1.15 and 1.8. In alkaline solutions, nucleophilic hydroxyl ions attack the electrophilic central carbon to produce the colourless triphenylmethanol or carbinol form of the dye.
This is especially used on "flux", or colourless enamel, as in the ground areas, rocks and trees. In the Royal Gold Cup, flux was also used for flesh areas as on a gold background it darkens slightly when hard to a suitable colour for skin. The rouge clair or "ruby glass" red, used so effectively here, was made by adding tiny particles of copper, silver and gold to the glass; here scientific tests have shown that copper was used. After firing the enamel was polished flush with the surrounding metal, which was presumably decorated last.
Formerly known as a resort town, it is home to the Thysville Caves, which encompass the entire range of the colourless African blind barb. It is home to a major FARDC garrison: the 1st Armoured Brigade was based here during the early '90s period.Ed. by Sandra W. Meditz and Tim Merrill, Country Study for Zaire, 1993, Library of Congress The 1st Armoured Brigade was first listed in the IISS Military Balance in 1982-83 edition, implying that the brigade may have been created during that period.IISS Military Balance 82/83, page 71 The city's other main industry is railway engineering.
The oral disc of Actinodendron arboreum has stripes that radiate from the mouth, and can reach a diameter of 10 to 20 centimetres. The column is elongated when expanded; it has a fairly small pedal disc and is thicker at the distal (upper) end. The tentacles are colourless, around 10 to 20 centimetres long and ramify fractally, being subdivided into branches and branchlets which makes the whole head of tentacles resemble a broccoli. The tentacles grow in whorls as the animal enlarges; the first whorl is six tentacles followed by further whorls of six, twelve and twenty-four tentacles.
While delivering the 15th D P Kohli Memorial Lecture for CBI on "Eclipse at Noon: Shadows Over India's Conscience" with nearly 3000 officers of the agency in the audience, Gandhi noted that "The CBI is seen as the government's hatchet, rather than honesty's ally. It is often called DDT — meaning not the dichloro diphenyl trichloroethane, the colourless, tasteless, odourless insecticide it should be, but the department of dirty tricks." In 2015, he wrote a letter to the President of India, Pranab Mukherjee, to reconsider the rejection of the mercy plea of the 1993 Mumbai serial blast convict, Yakub Memon.
The colour of an ionic compound is often different to the colour of an aqueous solution containing the constituent ions, or the hydrated form of the same compound. The anions in compounds with bonds with the most ionic character tend to be colourless (with an absorption band in the ultraviolet part of the spectrum). In compounds with less ionic character, their colour deepens through yellow, orange, red and black (as the absorption band shifts to longer wavelengths into the visible spectrum). The absorption band of simple cations shift toward shorter wavelength when they are involved in more covalent interactions.
Eucalyptus oils in the trade are categorized into three broad types according to their composition and main end-use: medicinal, perfumery and industrial. The most prevalent is the standard cineole-based "oil of eucalyptus", a colourless mobile liquid (yellow with age) with a penetrating, camphoraceous, woody-sweet scent.Lawless, J., The Illustrated Encyclopedia of Essential Oils, Element Books 1995 China produces about 75% of the world trade, but most of this is derived from the cineole fractions of camphor laurel rather than being true eucalyptus oil. Significant producers of true eucalyptus oil include South Africa, Portugal, Spain, Brazil, Australia, Chile, and Swaziland.
As one of Anthony Eden's biographers put it, she was "equally at home in the worlds of Hatfield and Fitzrovia",D. R. Thorpe (2003) Eden while a reviewer of her memoir wrote that "few lives can have touched so many social worlds, or graced them so elegantly".Ed Smith, The Times, 15 December 2007 Even so, Lady Avon did not impress everyone: after the future Prime Minister Margaret Thatcher met her at a Conservative Party ball in 1954, she wrote dismissively to her sister, "Mrs Anthony Eden received us. Really she is a most colourless personality".
Gehlenite is one of five, isostructural tetragonal crystal system minerals in the melilite group. The tetrahedral linkage within the structure is similar to that of an aluminosilicate framework structureLouisnathan S (1969), Refinement of the crystal structure of gehlenite, Canadian Mineralogist, 10, 822-837 and was once considered a feldspathoid-like mineralBest MG (2003), Igneous and Metamorphic Petrology (2nd Ed), 398, 693, 702-703 due to silica undersaturation. Gehlenite has a Mohs hardness of 5-6, a vitreous to greasy lustre, distinct to good cleavage and is yellow brown, greenish grey or colourless. Its streak is white or grey- white.
GHB can be manufactured with little knowledge of chemistry, as it involves the mixing of its two precursors, GBL and an alkali hydroxide such as sodium hydroxide, to form the GHB salt. Due to the ease of manufacture and the availability of its precursors, it is not usually produced in illicit laboratories like other synthetic drugs, but in private homes by low-level producers. GHB is "colourless and odourless". A 2006 report commissioned by a UK parliamentary committee found the use of GHB to be less dangerous than tobacco and alcohol in physical harm, dependence and social harms.
Phosphine (IUPAC name: phosphane) is a colourless, flammable, very toxic gas compound with the chemical formula PH3, classed as a pnictogen hydride. Pure phosphine is odourless, but technical grade samples have a highly unpleasant odour like rotting fish, due to the presence of substituted phosphine and diphosphane (P2H4). With traces of P2H4 present, PH3 is spontaneously flammable in air (pyrophoric), burning with a luminous flame. Phosphine is also the general name given to the class of organophosphorus compounds of substituted phosphanes—a class of phosphanes in which the hydrogen atoms have been replaced with organic derivative, having a general formula PR3.
In aqueous solution, flavins are yellow-coloured when oxidized, taking a red colour in the semi-reduced anionic state or blue in the neutral (semiquinone) state, and colourless when totally reduced. The oxidized and reduced forms are in fast equilibrium with the semiquinone (radical) form, shifted against the formation of the radical: ::Flox \+ FlredH2 ⇌ FlH• where Flox is the oxidized flavin, FlredH2 the reduced flavin (upon addition of two hydrogen atoms) and FlH• the semiquinone form (addition of one hydrogen atom). In the form of FADH2, it is one of the cofactors that can transfer electrons to the electron transfer chain.
The smaller eye and colourless fins help distinguish the tille trevally from the bigeye trevally The tille trevally is distributed through the tropical and subtropical waters of the Indian and west Pacific Oceans. In the western part of its range, the species distributed throughout South Africa and Madagascar waters north along the east African coast up to Tanzania, with an apparent break in its range from Tanzania to India. Its range continues from India east to South East Asia and the Indonesian Archipelago. The distribution extends south to northern Australia, north to Japan, and to Fiji in the east.
Khrushchev presented himself as a down-to-earth activist prepared to take up any challenge, contrasting with Malenkov who, though sophisticated, came across as colourless. Khrushchev arranged for the Kremlin grounds to be opened to the public, an act with "great public resonance". While both Malenkov and Khrushchev sought reforms to agriculture, Khrushchev's proposals were broader, and included the Virgin Lands Campaign, under which hundreds of thousands of young volunteers would settle and farm areas of Western Siberia and Northern Kazakhstan. While the scheme eventually became a tremendous disaster for Soviet agriculture, it was initially successful.
He increased taxes to pay for the great war against France and cracked down on radicalism. To engage the threat of Irish support for France, he engineered the Acts of Union 1800 and tried (but failed) to secure Catholic emancipation as part of the Union. He created the "new Toryism", which revived the Tory Party and enabled it to stay in power for the next quarter-century. The historian Asa Briggs argues that his personality did not endear itself to the British mind, for Pitt was too solitary and too colourless, and too often exuded an attitude of superiority.
Cormack, 388–391; Grove, 124 Roman gold glass beads were made by using an inner tube or rod to which the gold leaf was stuck. A larger tube was slid over that and the beads crimped off. Easily transported and very attractive, Roman gold glass beads have been found as far outside the Empire as the Wari-Bateshwar ruins in Bangladesh, and sites in China, Korea, Thailand and Malaysia.Francis, 91–93 Gold-band glass is a related Hellenistic and Roman technique, where strips of gold leaf, sandwiched between colourless glass, are used as part of the marbling effect in onyx glass.
Greenwood and Earnshaw, pp. 809–12 At room temperature, hydrogen chloride is a colourless gas, like all the hydrogen halides apart from hydrogen fluoride, since hydrogen cannot form strong hydrogen bonds to the larger electronegative chlorine atom; however, weak hydrogen bonding is present in solid crystalline hydrogen chloride at low temperatures, similar to the hydrogen fluoride structure, before disorder begins to prevail as the temperature is raised. Hydrochloric acid is a strong acid (pKa = −7) because the hydrogen bonds to chlorine are too weak to inhibit dissociation. The HCl/H2O system has many hydrates HCl·nH2O for n = 1, 2, 3, 4, and 6.
Despite attempts to rationalise it as the dimer of ClO3, it reacts more as though it were chloryl perchlorate, [ClO2]+[ClO4]−, which has been confirmed to be the correct structure of the solid. It hydrolyses in water to give a mixture of chloric and perchloric acids: the analogous reaction with anhydrous hydrogen fluoride does not proceed to completion. Dichlorine heptoxide (Cl2O7) is the anhydride of perchloric acid (HClO4) and can readily be obtained from it by dehydrating it with phosphoric acid at −10 °C and then distilling the product at −35 °C and 1 mmHg. It is a shock-sensitive, colourless oily liquid.
"...we considered colours, as far as they may be said to belong to the eye itself, and to depend on an action and reaction of the organ; next they attracted our attention as perceived in, or by means of, colourless mediums; and lastly, where we could consider them as belonging to particular substances. We have denominated the first, physiological, the second, physical, the third, chemical colours. The first are fleeting and not to be arrested; the next are passing, but still for a while enduring; the last may be made permanent for any length of time." Goethe, Theory of Colours, Introduction.
Cyanuric fluoride or 2,4,6-trifluoro-1,3,5-triazine is a chemical compound with the formula (CNF)3. It is a colourless, pungent liquid. It has been used as a precursor for fibre-reactive dyes, as a specific reagent for tyrosine residues in enzymes, and as a fluorinating agent. It is classified as an extremely hazardous substance in the United States as defined in Section 302 of the U.S. Emergency Planning and Community Right-to-Know Act (42 U.S.C. 11002), and is subject to strict reporting requirements by facilities which produce, store, or use it in significant quantities.
Salmonella spp appear to be yellow or colourless colonies, often with a dark centre. As there are many bacteria that also look like Salmonella on DCA, it is widely recommended that more selective agars are used for the identification of Salmonella, namely xylose lysine deoxycholate (XLD) agar. This growth medium is heat-sensitive and should be poured and cooled as soon as possible after addition of the deoxycholate, otherwise it tends to become very soft and difficult to handle. It has a pH of approximately 7.3, and when poured and cooled, appears light to dark pink in colour.
P. mucosa is a long and slender worm, growing to a maximum length of about and some 275 segments. The head and first segment (only visible from below) are dark-coloured, with some yellow pigment at the back of the head and the front of segment 2. The next two segments are colourless, and the remaining segments have a large dark spot dorsally, placed across the segment boundary. In the posterior part of the animal these tend to coalesce into a continuous dark band; additionally there are a pair of small yellow spots on each segment of this region.
Pentamethylantimony reacts with methyl lithium to yield a colourless lithium hexamethylantimonate in tetrahydrofuran. :Sb(CH3)5 \+ LiCH3 → Li(thf)Sb(CH3)6 Pentamethylantimony reacts with silsesquioxanes to yield tetramethylstibonium silsesquioxanes. eg (cyclo-C6H11)7Si7O9(OH)3 yields (cyclo-C6H11)7Si7O9(OSB(CH3)4)3. The reaction happens quickly when there are more than two OH groups. Phosphonic acids and phosphinic acids combine with pentamethylantimony to yield compounds like (CH3)4SbOP(O)Ph2, (CH3)4SbOP(O)(OH)Ph and (CH3)4SbOP(O)(OH)3, eliminating methane. Stannocene Sn(C5H5)2 combines with pentamethylantimony to produce bis(tetramethylstibonium)tetracyclopentadienylstannate ([(CH3)4Sb]2Sn(C5H5)4).
Its coccoliths are transparent and commonly colourless, but are formed of calcite which refracts light very efficiently in the water column. This, and the high concentrations caused by continual shedding of their coccoliths makes E. huxleyi blooms easily visible from space. Satellite images show that blooms can cover areas of more than 10,000 km^2, with complementary shipboard measurements indicating that E. huxleyi is by far the dominant phytoplankton species under these conditions. This species has been an inspiration for James Lovelock's Gaia hypothesis which claims that living organisms collectively self-regulate biogeochemistry and climate at nonrandom metastable states.
The organic compound 1,1,1-trichloroethane, also known as methyl chloroform, is a chloroalkane. This colourless, sweet-smelling liquid was once produced industrially in large quantities for use as a solvent.Manfred Rossberg, Wilhelm Lendle, Gerhard Pfleiderer, Adolf Tögel, Eberhard-Ludwig Dreher, Ernst Langer, Heinz Rassaerts, Peter Kleinschmidt, Heinz Strack, Richard Cook, Uwe Beck, Karl-August Lipper, Theodore R. Torkelson, Eckhard Löser, Klaus K. Beutel, Trevor Mann "Chlorinated Hydrocarbons" in Ullmann's Encyclopedia of Industrial Chemistry 2006, Wiley-VCH, Weinheim. . It is regulated by the Montreal Protocol as an ozone-depleting substance and its use is being rapidly phased out.
Evidence from Pompeii suggests that molten hot glass may have been introduced as early as the mid-1st century CE. Blank vessels were then annealed, fixed to lathes and cut and polished on all surfaces to achieve their final shape.Grose, D.F., Early Imperial Roman cast glass: The translucent coloured and colourless fine wares, in Roman Glass: two centuries of art and invention, M. Newby and K. Painter, Editors. 1991, Society of Antiquaries of London: London. Pliny the Elder indicates in his Natural History (36.193) that lathes were used in the production of most glass of the mid-1st century.
The term is therefore unsatisfactory in several respects, although clear in an Ancient Egyptian context, and is increasingly rejected in museum and archaeological usage. The British Museum now calls this material "glazed composition", with the following note in the "information" box on their online collection database: > The term is used for objects with a body made of finely powdered quartz > grains fused together with small amounts of alkali and/or lime through > partial heating. The bodies are usually colourless but natural impurities > give them a brown or greyish tint. Colourants can also be added to give it > an artificial colour.
Agar plates are used as a canvas, while pigmented or fluorescent bacteria and yeasts represent the paint. In order to preserve a piece of microbial art after a sufficient incubation, the microbe culture is sealed with epoxy. Microbe species can be chosen for their natural colours to form a palette for the artwork. Suitable species of bacteria (with their colours) include Bacillus subtilis (cream to brown), Chromobacterium violaceum (violet), Escherichia coli (colourless), Micrococcus luteus (yellow), Micrococcus roseus (pink), Proteus mirabilis, Pseudomonas aeruginosa (brown), Pseudomonas fluorescens (naturally blue-green fluorescent with pyoverdine), Serratia marcescens (pink or orange), Staphylococcus aureus (yellow), and Vibrio fischeri (bioluminescent).
2-Phenylpyridine is an organic compound with the formula C6H5C5H4N. It is a colourless viscous liquid. The compound and related derivatives have attracted interest as precursors to highly fluorescent metal complexes of possible value as organic light emitting diodes (OLEDs). The compound is prepared by the reaction of phenyl lithium with pyridine: :C6H5Li + C5H5N → C6H5-C5H4N + LiH The reaction of iridium trichloride with 2-phenylpyridine proceeds via cyclometallation to give the chloride-bridged complex: :4 C6H5-C5H4N + 2 IrCl3(H2O)3 → Ir2Cl2(C6H4-C5H4N)4 \+ 4 HCl This complex can be converted to the pictured tris(cyclometallated) derivative.
Like other sillaginids, S. parvisquamis is a benthic predator and is known to consume a variety of crustaceans, molluscs and annelid worms. Studies in the Buzen Sea of Japan have found the small-scale whiting spawns from May to July, while laboratory studies have similarly found that spawning occurs from May to September with a peak from June to July. Laboratory conditions also showed that spawning occurs at night predominantly between 20:30 and 22:00 hours. The eggs are buoyant and spherical in shape with an average diameter of 0.71 mm and are transparent and colourless.
Diplonemidae is a family of biflagellated unicellular protists that may be among the more diverse and common groups of planktonic organisms in the ocean. Although this family is currently made up of three named genera; Diplonema, Rhynchopus, and Hemistasia, there likely exist thousands of still unnamed genera. Organisms are generally colourless and oblong in shape, with two flagella emerging from a subapical pocket. They possess a large mitochondrial genome composed of fragmented linear DNA These non-coding sequences must be massively trans-spliced, making it one of the most complicated post- transcriptional editing process known to eukaryotes.
This led to the Winjeel basic trainer and Australian industry co-partnership in production of the CAC Sabre and Canberra jets; such local participation has continued to figure in major RAAF aircraft acquisitions.Stephens, Going Solo, p. 188 He refused to update the command structure of the Air Force from one based on region to one of function, something his successor, Air Marshal Hardman, would accomplish, and has been criticised for a systemic resistance to change.Helson, Ten Years at the Top, pp. 253–254 Jones was described in David Horner's The Commanders as "a steady, sincere but colourless leader",Horner, The Commanders, p.
Natron deposits in the Era Kohor crater in the Tibesti Mountains, Chad Natron is a naturally occurring mixture of sodium carbonate decahydrate (Na2CO3·10H2O, a kind of soda ash) and around 17% sodium bicarbonate (also called baking soda, NaHCO3) along with small quantities of sodium chloride and sodium sulfate. Natron is white to colourless when pure, varying to gray or yellow with impurities. Natron deposits are sometimes found in saline lake beds which arose in arid environments. Throughout history natron has had many practical applications that continue today in the wide range of modern uses of its constituent mineral components.
Baijiu (), also known as shaojiu (/), is a Chinese clear, colourless liquor typically coming in between 35% and 60% alcohol by volume (ABV). Each type of baijiu uses a distinct type of Qū for fermentation unique to the distillery for the distinct and characteristic flavour profile. Baijiu is a clear liquid usually distilled from fermented sorghum, although other grains may be used; some southeastern Chinese styles may employ rice or glutinous rice, while other Chinese varieties may use wheat, barley, millet, or Job's tears (Chinese: 薏苡 yìyǐ) in their mash bills. The qū starter culture used in the production of baijiu is usually made from pulverized wheat grain or steamed rice.
Fragments from the 14th-century screen were discovered during the 1980s restoration works and are now kept in the church's lapidarium in the East crypt. By the end of the 18th century, the entire church interior had been painted white, the colourful Medieval stained glass windows had been replaced by colourless glass, and the church looked distinctly Baroque. The north transept holds some epitaphs, of which the one for Egidius Ruyschen in Renaissance style is probably the most original. Nearby is the impressive tomb of the Count and Countess van den Bergh (Johannes Bossier, 1685), which was transferred from the Dominican church of Maastricht.
The council approved three creeds.Hahn, §§ 153-155, cited in . Whether or not the so-called "fourth formula"Hahn, § 156, cited in . is to be ascribed to a continuation of this synod or to a subsequent but distinct assembly of the same year, its aim is like that of the first three; while repudiating certain Arian formulas it avoids the orthodox term homoousios, fiercely advocated by Athanasius of Alexandria and accepted by the First Council of Nicaea (Nicaea I). The somewhat colourless compromise doubtless proceeded from the party of Eusebius of Nicomedia, and proved not unacceptable to the more nearly orthodox members of the synod.
Delacroix's pupil and chief assistant of over a decade, Pierre Andrieu, recorded that Delacroix had told him the inspiration for these drops had come in part from the water drops visible on the nereids in Rubens' The Landing of Marie de' Medici at Marseilles, and that the drops on The Barque of Dante were Delacroix's point of departure as a colourist. Lee Johnson discussing these drops comments that "the analytical principle [Delacroix] applies of dividing into pure coloured components an object that to the average eye would appear monochrome or colourless, is of far-reaching significance for the future."Delacroix, Lee Johnson, W.W.Norton & Company, Inc., New York, 1963.
The only possible remedy, namely the contouring of the letters by way of a prepared pad underneath, whose bas-relief forms correlate perfectly with those of the high-relief stamp, was not technically feasible then, either. This proves Montserrat's high-relief hypothesis to be untenable. If the text had been carved directly into the foil as with other amulets, the stylus could have left only simple lines. According to Brekle, the applied printing technique has much in common with the later method of drypoint etching, by which an image is incised into a copper plate; however, unlike drypoint, MS 5236 is a colourless blind print.
Ordinary soda-lime glass appears colourless to the naked eye when it is thin, although iron oxide impurities produce a green tint which becomes evident in thick pieces or can be seen with the aid of scientific instruments. A number of additives are used to reduce the green tint, particularly if the glass is to be used for plain window glass, rather than stained glass windows. Additives that reduce the green tint include manganese dioxide which produces sodium permanganate, and may result in a slightly mauve tint, characteristic of the glass in older houses in New England. Selenium has been used for the same purpose.
Formation of PSI+ prion causes S. cerevisiae cells with nonsense-mutation in ade1 gene to convert red pigment (colony below) into a colourless compound, causing colonies to become white (above) A fungal prion is a prion that infects fungal hosts. Fungal prions are naturally occurring proteins that can switch between multiple, structurally distinct conformations, at least one of which is self-propagating and transmissible to other prions. This transmission of protein state represents an epigenetic phenomenon where information is encoded in the protein structure itself, instead of in nucleic acids. Several prion-forming proteins have been identified in fungi, primarily in the yeast Saccharomyces cerevisiae.
A new successful method of population control is by the injection of thiosulfate-citrate-bile salts-sucrose agar (TCBS). Only one injection is needed, leading to the organism's death in 24 hours from a contagious disease marked by "discoloured and necrotic skin, ulcerations, loss of body turgor, accumulation of colourless mucus on many spines especially at their tip, and loss of spines. Blisters on the dorsal integument broke through the skin surface and resulted in large, open sores that exposed the internal organs." An autonomous starfish-killing robot called COTSBot has been developed and as of September 2015 was close to being ready for trials on the Great Barrier Reef.
The crested oyster is a rather irregular triangular or oval shape and grows to a length of about . The two valves are quite different; the left one is deeply concave, has a raised margin and is fixed to the substrate while the right one is flattish and fits inside the other. The valves are thick with variable surface sculpturing, the whitish colour being obscured by mud, algal growth and encrusting organisms. The inside of the valves is pearly grey or greenish, and the muscle scar is colourless, a fact that distinguishes this species from the much larger eastern oyster (Crassostrea virginica) which has a purple muscle scar.
In 1977 architectural writer Sutherland Lyall described the finished estate as follows: "There is a nice, colourful, cheap and cheerful air about in the squares which are mostly planted out in grids of trees... In the squares the brightly coloured GRP more or less comes off. Deliberate or not it is two fingers to the bureaucrats who insist that architecture should be dignified and banal and colourless... But behind the back it is straight Butlins: long rows of corrugated plastic walls with the occasional service pipe running up the walls and across gaps between rows of houses." \- text of an article by Sutherland Lyall, Building Design, 12 August 1977.
In the 1570s, Spanish physician Francisco Hernández described a remarkably sweet plant known to the Aztecs as Tzonpelic xihuitl, meaning "sweet herb". This reference, accompanied by an accurate description and illustration of the plant, led to a group of pharmacognocists in 1985 to a previously unrecognised, intensely sweet chemical that can provide sweetness without tooth decay. Cesar M. Compadre, and A. Douglas Kinghorn, from the University of Illinois at Chicago isolated and identified the sweet compound from the leaves and flowers of the Lippia dulcis plant, in Mexico. The researchers noted the chemical structure of the colourless oil, and named it hernandulcin after Francisco Hernandez.
"das zentrale Axiom von Newtons Farbentheorie, daß in dem weißen, farblosen Licht alle Farben enthalten seien" ("the central axiom of Newton's colour theory that there were all colours in the white, colourless light") Castel's 1740 comparison of Newton's spectral colour description with his explanation in terms of the interaction of light and dark, which Goethe later developed into his Theory of Colours Goethe's starting point was the supposed discovery of how Newton erred in the prismatic experiment,Matthaei, Rupprecht. Über die Anfänge von Goethes Farbenlehre (On the beginnings of Goethe's Theory of Colours). In: Jahrbuch der Goethe- Gesellschaft (Yearbook of the Goethe Society) 11, 1949, p.
Petrol Station Pump in Sydney, New South Wales, selling E10 fuel (Green handle) Bioethanol, which is often shortened to ‘ethanol’, is colourless alcohol made by the fermentation of biomass, using glucose derived from sugars (for example from sugar cane, sugar beet or molasses), starch (corn, wheat and grains) or cellulose (forest products). Ethanol produced from renewable energy sources, biomass, is the most promising biofuel for the future. In Australia, there are three major fuel ethanol production facilities that produce ethanol primarily from waste wheat starch, grain sorghum and molasses. The total capacity to produce ethanol from these facilities is around 440 million litres a year.
As has been mentioned, for transparent objects they utilised a specific recipe but it is also true that they did not usually achieve pure transparency but very close results: transparent glasses with green, blue or grey-blue hues. The majority of the Sasanian glass is colourless (with transparent unintended colours caused by impurities in the silica). There are generally yellowish-green or yellowish-brown tinges and a characteristic smoky-brown tinge frequently associated with the face-cut bowls. Whole vessels in plain colours are far less common among the Sasanians to the extent that many of the full-coloured examples are believed to be imported.
Due to the basicity of the Se2− and Te2− ions, the alkali metal selenides and tellurides are alkaline in solution; when reacted directly with selenium and tellurium, alkali metal polyselenides and polytellurides are formed along with the selenides and tellurides with the and ions. They may be obtained directly from the elements in liquid ammonia or when air is not present, and are colourless, water-soluble compounds that air oxidises quickly back to selenium or tellurium. The alkali metal polonides are all ionic compounds containing the Po2− ion; they are very chemically stable and can be produced by direct reaction of the elements at around 300–400 °C.
They were made in considerable quantities in the Syro-Palestinian coast and were widely traded and exported to several trading centres throughout the Mediterranean. Earlier examples were made of clear greenish, brownish or almost colourless glass, while later on they often had green, amber, blue or wine-purple colour. Usually, they were decorated with linear-cut concentric circles at the bottom or right under the rim either on the inside or the outside (Tatton-Brown and Andrews 2004). They were made in an open mould, which is in fact a relatively cheap technique that requires less effort put and it was this that allowed their large-scale production.
This boule is usually no larger than 2.5 centimetres in diameter and 10 centimetres long; it is an opaque black to begin with, requiring further annealing in an oxidizing atmosphere in order to make the crystal colourless and to relieve strain. This is done at over 1000 °C for 12 hours. Thin films of SrTiO3 can be grown epitaxially by various methods, including pulsed laser deposition, molecular beam epitaxy, RF sputtering and atomic layer deposition. As in most thin films, different growth methods can result in significantly different defect and impurity densities and crystalline quality, resulting in a large variation of the electronic and optical properties.
The Julia Felix, also sunk during the 3rd century AD, was carrying as part of its cargo glass cullet presumably for recycling.Silvestri et al 2008 Trace element analysis of colourless glass showed these were made using sands from different sources and giving some support to the de-centralised production hypothesis. By the 9th century the raw materials for glass shift again to quartz pebbles and plant ash and the 'forest glass' of medieval Europe. Natron was no longer in use and the low lime composition of the Bet'eliezer glass would be suggestive of a decline in access to the material from at least the 6th century onwards.
This colourless salt consists of a sulfonium cation and the triflate anion. Many related salts are known including those with other noncoordinating anions and those with diverse substituents on the phenyl rings. The triphenylsulfonium salts absorb at 233 nm, which induces the series of reactions shown below.W. D. Hinsberg, G. M. Wallraff, Lithographic Resists, Kirk-Othmer Encyclopedia of Chemical Technology, Wiley-VCH, Weinheim, 2005. (Published online: 17 June 2005) As this series of reactions is irreversible, triphenylsulfonium triflate is a photoacid generator. :[(C6H5)3S+][CF3SO] + hν → [(C6H5)2S+.][CF3SO] + C6H :[(C6H5)2S+.][CF3SO] + C6H → (C6H5C6H4)(C6H5)S + [CF3SO][H+] Applications of these photoacids include photolithographyJ.
Volumetric flasks are generally colourless but may be amber-coloured for the handling of light- sensitive compounds such as silver nitrate or vitamin A. A modification of the volumetric flask exists for dealing with large quantities of solids that are to be transferred into a volumetric vessel for dissolution. Such a flask has a wide mouth and known as a Kohlrausch volumetric flask. This kind of volumetric flask is commonly used in analysis of the sugar content in sugar beets. While conventional volumetric flasks have a single mark, industrial volumetric tests in analytical chemistry and food chemistry may employ specialized volumetric flasks with multiple marks to combine several accurately measured volumes.
Glass pieces are typically dated by stylistic comparisons to other pieces from the era.Lukens 2013, 199 The majority of the decorative traditions used in the Early Islamic Period concerned the manipulation of the glass itself, and included trail-application, carving, and mold-blowing. As mentioned previously, glass-carving and trail application are a continuation of older techniques, the former associated with Sassanian glassmaking and the latter with Roman traditions. In relief cutting, a specialized form of glass-carving most often used on colourless and transparent glass, "the area surrounding the decorative elements was carved back to the ground, thus leaving the former in relief".
The poem begins with a note that explains the connection between pixies and his home:Salmon 1906 p. 22 "At a small distance from a village in that county [Devonshire], half-way up a wood-cover'd Hill, is an Excavation, called the Pixies' Parlour [...] To this place the Author conducted a party of young Ladies during the summer months of the year, 1793—one of whom (of stature elegantly small, and of complexion colourless yet clear) was proclaimed the Fairy Queen—on which occasion the following Irregular Ode was written".Mays 2001 qtd. pp. 108–109 The fourth stanza connects Coleridge with a "youthful Bard":Ashton 1997 p.
Th4+: __ / O2−: __ Despite the anomalous electron configuration for gaseous thorium atoms, metallic thorium shows significant 5f involvement. A hypothetical metallic state of thorium that had the [Rn]6d27s2 configuration with the 5f orbitals above the Fermi level should be hexagonal close packed like the group 4 elements titanium, zirconium, and hafnium, and not face- centred cubic as it actually is. The actual crystal structure can only be explained when the 5f states are invoked, proving that thorium, and not protactinium, acts as the first actinide metallurgically. Tetravalent thorium compounds are usually colourless or yellow, like those of silver or lead, as the Th4+ ion has no 5f or 6d electrons.
Baxter translated Rindfleisch's Pathological Histology for the New Sydenham Society; prepared the fourth edition of Garrod's Essentials of Materia Medica; and made some valuable experiments on "The Action of the Chinchona Alkaloids and their Congeners on Bacteria and Colourless Blood Corpuscles" described in the Practitioner (1873). He also drew up an able "Report on the Experimental Study of certain Disinfectants" printed in the Privy Council Reports (1875); and contributed a remarkable article to the British and Foreign Medico-Chirurgical Review in 1877 on the vaso-motor nervous system. His minor writings include a series of physiological notes which he contributed to the Academy for many years.
The album received mixed reviews. AllMusic gave Reason 2.5 stars out of 5, with Stephen Thomas Erlewine stating that "[the songs] are colourless and characterless, sounding as if their main goal is to get on pop radio" and that the album "is a real disappointment after the very good, very promising Northern Star". The Guardian gave Reason 2 out of 5 stars, with Alexis Petridis stating that the album "settles on a direction, sounds confident and efficient and wrings the last drops of originality out of Melanie C". In a 2007 interview with The Guardian, Chisholm stated that she thought that the songs on Reason "could have been stronger".
Following the practice of the time, the Pearsons used a technique in which the image was painted in enamels on sheets of colourless glass and then fired. The Pearsons exhibited regularly throughout the 1780s and 1790s at their homes in London, first in Church Street, Westminster, and later in Great Newport Street. They also showed at the new Pantheon in Oxford Street. In the last years of the 18th century Pearson widened her repertoire to include copies on glass of famous paintings, and early in 1791 she finished the first of the three sets she painted after the seven Raphael Cartoons, then at Windsor Castle.
The seat of the bishopric was established in the city and all churches belonged to the diocese, staffed by the bishop's clergy.Blair Church in Anglo-Saxon Society pp. 34–39 Most modern historians have noted how the Gregorian missionaries come across in Bede's account as colourless and boring, compared to the Irish missionaries in Northumbria, and this is related directly to the way Bede gathered his information. The historian Henry Mayr- Harting argues that in addition, most of the Gregorian missionaries were concerned with the Roman virtue of gravitas, or personal dignity not given to emotional displays, and this would have limited the colourful stories available about them.
N-(2-Carboxyethyl)iminodiacetic acid is a colourless solid that was shown to be very well degradable in sewage plant simulations (98% after eight weeks) and to be exceptionally low in toxicity. Elsewhere, the poor microbial degradability and adsorbability of β-ADA is pointed out.Hessisches Landesamt für Umwelt und Geologie, 6.12 Komplexbildner, S. 12/3, 2003. The contradictory assessment of the degradability of β-ADA, the weaker complex formation compared to the (rapidly biodegradable) methylglycine diacetic acid (MGDA, Trilon M) and the lower stability in wide temperature and pH ranges have substantially contributed to the breakthrough of MGDA as the most suitable substitute for EDTA.
Its fins vary from colourless to blackish-grey and the dorsal fins have between one and three dark stripes with a yellow or orange background colour. The margins of the fin are frequently fin margins yellow and the caudal fin is marked with many dark spots which are arranged in irregular bands. The body of Gobiomorphus coxii is nearly cylindrical and tapers towards the tail, the head is large with a blunt, round snout and the quite small eyes are positioned high on the head. The mouth is relatively large, oblique and turned upwards with the lips ending lust below the front part of the eyes.
In this novel an old Raj family comes newly on the scene, the Laytons of Pankot, an imaginary hill station in India. Now an army captain, Ronald Merrick, a self-made man of the lower middle class and the former police official in charge of the Daphne Manners case, begins to insinuate himself subtly into the Layton family. We learn what the Laytons do not know, that in a searing session with the incarcerated Hari Kumar, Merrick tortured and molested him. Susan, the younger Layton sister, driven by a sense of her own nothingness, marries Teddie Bingham, a colourless and conventional officer in the prestigious Pankot Rifles regiment.

The picture would benefit from a lot more > pruning by editor David Wages. Time Out New York feels that despite "an average script and a colourless lead performance from Donahue" the film "[emerges] as a majestically simple, sweeping cavalry Western, a little reminiscent of Ford in mood and manner. Brilliantly shot by William Clothier, it tends to have its cake and eat it by indulging in a spectacular massacre before introducing the liberal message, but still goes further than most in according respect to the Indian by letting him speak his own language (with subtitles)." Peter Bogdanovich called the film: > One of Walsh's weakest pictures, caused mainly by an intolerably bad cast > and a predictable script.
The Jubilee Diamond, originally known as the Reitz Diamond is a colourless, cushion-shaped diamond weighing 245.35 carats (49.07 grams), making it the sixth largest diamond in the world. It was originally named after Francis William Reitz, the then president of the Orange Free State where the stone was discovered, before being renamed to honour the 60th anniversary of the coronation of Queen Victoria in 1897. The original stone, a rough octahedron weighing 650.80 carats (130.16 g), was discovered in 1895 at the Jagersfontein Mine in South Africa. A consortium of diamond merchants from London purchased it along with its even larger sister, the Excelsior, in 1896, and sent it to Amsterdam where it was polished by M.B. Barends.
Thirty minutes into the match, Gillespie's pass was intercepted by Harry Wake on the edge of Cardiff's penalty area. Rather than clear the ball, Wake hesitated in possession and was tackled by Tunstall who advanced on Cardiff goalkeeper Farquharson before scoring the opening goal of the match from . Tunstall nearly went through on goal a second time shortly after, but was quickly closed down by the Cardiff defence. The People noted that, based on the first half, the match "would have gone down to history as one of the best finals ever played", while The Express wrote that the first half was "not colourless by any means but it was not picturesque".
I opened the letter, called Bill, and said, 'Look, I can't do this; it is in Czech.' She said, 'Oh, I'm sorry; how stupid; hang on for a moment.' At the back of my desk there was a little open bottle of colourless liquid, with a brush, and she dipped the brush in the liquid, passed it over the whole of the front of the letter and to my amazed eyes red writing appeared at right angles to the Czech text and it was in German. Then she turned the letter over and did the same on the rear side, so that I had two sides of what was in fact a German report.
With the change in architectural style during the Renaissance period in Europe, the use of large stained glass windows became much less prevalent, although stained glass had a major revival with Gothic Revival architecture in the 19th century. During the 13th century, the island of Murano, Venice, became a centre for glass making, building on medieval techniques to produce colourful ornamental pieces in large quantities. Murano glass makers developed the exceptionally clear colourless glass cristallo, so called for its resemblance to natural crystal, and extensively used for windows, mirrors, ships' lanterns, and lenses. In the 13th, 14th, and 15th centuries, enamelling and gilding on glass vessels was perfected in Egypt and Syria.
In certain areas of the Pyrenees, aguardiente, known locally to Catalonians as aiguardent, is used as an essential ingredient in the preparation of tupí, a type of cheese.Formatge de tupí - Ingredients i preparació artesanal Galicia is renowned for the quality and variety of its aguardientes, probably the most famous of which is augardente de bagazo (Aguardiente de Orujo), which is obtained from the distillation of the pomace of grapes, and is clear and colourless. It typically contains over 50% alcohol, sometimes significantly more, and is still made traditionally in many villages across Galicia today. Augardente de herbas, usually yellow in colour, is a sweet liqueur made with Augardente de bagazo and herbs (herbas), with chamomile being a substantial ingredient.
There have been numerous biographies about Lillie Langtry, (she also wrote her own autobiography) but little has been written about her first husband Edward (Ned) Langtry. What has been written often paints him in a negative light. He has been referred to as "a colourless sportsman"; "a pudgy chap, his weak mouth overhung with a walrus moustache, and his conversation powers were limited"; "petulantly determined on his own importance......he was weak and indolent and also, surprisingly shy"; "a meek, weak husband and no money";"uneasily complaisant husband". If these descriptions are accurate, it is difficult to understand why a woman as gifted as Lillie would marry a man with such shortcomings.
A red diamond is a diamond which displays red colour and exhibits the same mineral properties as colourless diamonds. Red diamonds are commonly known as the most expensive and the rarest diamond colour in the world, even more so than pink diamonds or blue diamonds, as very few red diamonds having been found. Red diamonds, just like pink diamonds, are greatly debated as to the source of their colour, but the gemological community most commonly attributes both colours to gliding atoms in the diamond's structure as it undergoes enormous pressure during its formation. Red diamonds are among the 12 colours of fancy colour diamonds, and have the most expensive price per carat.
The original lineup included vocalist Garçe (Simon) Allard, guitarist Tristan Garel-Funk, bassist Cliff Silver, drummer Nigel Pollard and keyboardist/saxophonist David Wood. Following their debut EP Clé and the "Colourless Dream" single, both issued in 1981, they released their debut studio album, Epic Garden Music in 1982. It reached No. 21 in the UK Independent Albums Chart.Lazell, Barry (1998) Indie Hits 1980–1989, Cherry Red Books, , p. 195 During this initial period they recorded a John Peel Session for the BBC,"Sad Lovers and Giants", Keeping It Peel, BBC, retrieved 2011-01-15 and a live concert for Radio Netherlands Worldwide in 1983 (later released as the album Total Sound in 1986).
Although much emphasis is put onto the color of the egg yolk, it does not reliably reflect the nutritional value of an egg. For example, some of the natural pigments that produce a rich yolk color are xanthophylls without much nutritional value, rather than the carotenoids that act as provitamin A in the body. Also, a diet rich in vitamin A itself, but without A-provitamins or xanthophylls, can produce practically colourless yolks that are just as nutritious as any richly colored yolks. Yolks, particularly from free-range eggs, can be of a wide range of colors, ranging from nearly white, through yellow and orange, to practically red, or even olive green, depending on the pigments in their feed.
Phacus consists of organisms that are microscopic photosynthetic Euglenoids, which are a group of single celled, chloroplast- containing autotrophs within the phylum Euglenozoa, though the majority of genera within the phylum actually do not contain chloroplasts and are colourless. Generally these species are small, free swimming and exhibit a vibrant green colour. What sets the genus apart from other photosynthetic species is the presence of its rigid cytoskeleton (although some species have semi-rigid or plastic cytoskeleton) made up of pellicular strips and its predominantly flat, leaf-shaped structure. Many different species express secondary fusion of these pellicular strips and many of the strips have a variety of shapes including S-shaped, A-shaped, M-shaped or plateau.
By 1164 Ralph had acquired the livings of Aynho, Northamptonshire, and Finchingfield, Essex, and served them both by vicars.Biography of Ralph de Diceto (August, 2016) Although Ralph's narrative is colourless and although he was one of those who showed some sympathy for Becket at the council of Northampton in 1164, his correspondence shows that he regarded the archbishop's conduct as ill-considered and that he gave advice to those whom Becket regarded as his chief enemies. Ralph was selected in 1166 as the envoy of the English bishops when they protested against the excommunications launched by Becket. But, apart from this episode, which he characteristically neglects to record, he remained in the background.
Polarizing filter, Atlantic Ocean 1989 A polarizing filter, used for both color and black-and-white photography, is colourless and does not affect colour balance, but filters out light with a particular direction of polarisation. This reduces oblique reflections from non-metallic surfaces, can darken the sky in colour photography (in monochrome photography colour filters are more effective), and can saturate the image more by eliminating unwanted reflections. Linear polarising filters, while effective, can interfere with metering and auto-focus mechanisms when mirrors or beam-splitters are in the light path, as in the digital single lens reflex camera; a circular polarizer is also effective, and does not affect metering or auto-focus.
Archduke Joseph August Viktor Klemens Maria of Austria, Prince of Hungary and Bohemia (9 August 1872 - 6 July 1962) was a Feldmarschall (field marshal) of the Austro-Hungarian Army and for a short period head of state of Hungary. He was a member of the House of Habsburg-Lorraine, the eldest son of Archduke Joseph Karl of Austria (1833–1905) and his wife Princess Clotilde of Saxe- Coburg and Gotha (1846–1927). Joseph August's grandfather had been Palatine Joseph of Hungary (1776–1847), Palatine and Viceroy of Hungary, a younger son of Emperor Leopold II. The Archduke Joseph Diamond, a 76.02 carat colourless diamond with internal flawless clarity, is named after the Archduke and officially recorded as his property.
The name Opala may come from the opal, which is a precious stone, colourless when extracted from the soil, but which acquires multiple tones when exposed to light. Some commented that the name was a portmanteau of the brand name "Opel", and the Chevy Impala, as the model was derived from the German Opel Rekord, and one of its engines (the 230 in³, and later, 250 in³ Chevrolet straight-six) was also used in the North American Chevrolet Impala. GM claims that this was not their intention, as the name Opala - one of six finalists from thousands of suggestions - was chosen by a journalist. Its rapid acceptance with the general public led to the approval of the choice.
Crystal cell sizes are a=21.387 b=7.9328 c=15.184 β=90.657 V=2576 formulas per cell Z=8. The way the components are arranged in the crystal is that there are six nitrates around each cerium atom, however to get to the average of five per cerium, two nitrate groups on each, link the atoms into a chain along the an axis. There are anhydrous double nitrates such as Ce2Rb3(NO3)9 and Ce2K3(NO3)9. The potassium salt, Ce2K3(NO3)9 can be made by using the water solution of potassium nitrate and cerous nitrate in 3:2 molar ratio, evaporated at 40 °C. The crystals are colourless cubic from space group P4132\.
Antoine Lavoisier suggested instead the name azote, from the Greek ἀζωτικός "no life", as it is an asphyxiant gas; this name is instead used in many languages, such as French, Italian, Russian, Romanian and Turkish, and appears in the English names of some nitrogen compounds such as hydrazine, azides and azo compounds. Nitrogen is the lightest member of group 15 of the periodic table, often called the pnictogens. It is a common element in the universe, estimated at about seventh in total abundance in the Milky Way and the Solar System. At standard temperature and pressure, two atoms of the element bind to form dinitrogen, a colourless and odorless diatomic gas with the formula N2.
Glass vessel from the 2nd century AD, found in Bosanski Novi The earliest Roman glass follows Hellenistic traditions and uses strongly coloured and 'mosaic' patterned glass. During the late Republican period new highly coloured striped wares with a fusion of dozens of monochrome and lace-work strips were introduced. During this period there is some evidence that styles of glass varied geographically, with the translucent coloured fine wares of the early 1st century notably 'western' in origin, whilst the later colourless fine wares are more 'international'. These objects also represent the first with a distinctly Roman style unrelated to the Hellenistic casting traditions on which they are based, and are characterised by novel rich colours.
Dirhenium decacarbonyl is the most common entry to organorhenium chemistry. Its reduction with sodium amalgam gives Na[Re(CO)5] with rhenium in the formal oxidation state −1. Dirhenium decacarbonyl can be oxidised with bromine to bromopentacarbonylrhenium(I): :Re2(CO)10 \+ Br2 → 2 Re(CO)5Br Reduction of this pentacarbonyl with zinc and acetic acid gives pentacarbonylhydridorhenium: :Re(CO)5Br + Zn + HOAc → Re(CO)5H + ZnBr(OAc) Methylrhenium trioxide ("MTO"), CH3ReO3 is a volatile, colourless solid has been used as a catalyst in some laboratory experiments. It can be prepared by many routes, a typical method is the reaction of Re2O7 and tetramethyltin: :Re2O7 \+ (CH3)4Sn → CH3ReO3 \+ (CH3)3SnOReO3 Analogous alkyl and aryl derivatives are known.
The colour coating has started to flake off this PY27/7W bulb, a relatively new problem The amber bulbs commonly used in turn signals with colourless lenses are no longer made with cadmium glass, since various regulations worldwide, including the European RoHS directive, banned cadmium because of its toxicity. Amber glass made without cadmium is relatively costly, so most amber bulbs are now made with clear glass dipped in an amber coating. Some of these coatings are not as durable as the bulb envelopes; with prolonged heat-cool cycles, the coating may flake off the bulb glass, or its colour may fade. This causes the turn signal to emit white light, rather than the required amber light.
A variety of reduced oxides (suboxides) of titanium are known, mainly reduced stoichiometries of titanium dioxide obtained by atmospheric plasma spraying. Ti3O5, described as a Ti(IV)-Ti(III) species, is a purple semiconductor produced by reduction of TiO2 with hydrogen at high temperatures, and is used industrially when surfaces need to be vapour-coated with titanium dioxide: it evaporates as pure TiO, whereas TiO2 evaporates as a mixture of oxides and deposits coatings with variable refractive index. Also known is Ti2O3, with the corundum structure, and TiO, with the rock salt structure, although often nonstoichiometric. The alkoxides of titanium(IV), prepared by reacting TiCl4 with alcohols, are colourless compounds that convert to the dioxide on reaction with water.
The two colours in effect cancel each other out to produce a clear glass. Experimental manufacture of potash glass emulating Theophilus’ recipes has resulted in colours ranging from colourless to yellow, amber, brown, green, blue, pink and purple.Stern et al 2004, 153Newton 1978, 59Davison 2003, 7 Variation in colour hue and depth would also probably be affected by the source of the beech wood ash, depending on the soil chemistry where the beech tree grew, the age of the tree and the climate conditions.Royce-Roll 1994, 76Stern et al 2004, 143 Some of the stronger reds, blues and greens that are a feature of medieval stained glass rely on the addition of copper oxides.
Despite its name, the compound contains no bromine—theobromine is derived from Theobroma, the name of the genus of the cacao tree (which itself is made up of the Greek roots theo ("god") and broma ("food"), meaning "food of the gods" (note: the book incorrectly states that the name "theobroma" is derived from Latin)) with the suffix -ine given to alkaloids and other basic nitrogen-containing compounds. Theobromine is a slightly water-soluble (330 mg/L), crystalline, bitter powder. Theobromine is white or colourless, but commercial samples can be yellowish. It has an effect similar to, but lesser than, that of caffeine in the human nervous system, making it a lesser homologue.
Diagram of the key morphological structures of Aspergillus wentii, including the conidiophore, conidia, conidial head, vesicle, phialides, metullae, stipe, and foot cell Aspergillus wentii produces single-celled, globose, conidia (singular conidium) in unbranched, filamentous chains. Young asexual conidia (also called spores) start off smooth, colourless, and ellipsoidal before maturing into rough, globose spores approximately 4.5-5 µm in diameter. Aspergillus wentii conidia can appear anywhere from darker yellow to brown in colour when mature and have a single wall, unlike related species Aspergillus tamarii whose conidia have a double wall membrane. The elongating chains of conidia are dispersed through slightly pigmented, vase-shaped structures known as phialides that are around 6-8 µm.
Some of these letters were published in 1852 by the Earl of Albemarle, strung together as Memoirs of the Marquis of Rockingham and his contemporaries. Two shortish but valuable studies have appeared since the muniments were deposited here, viz: The early career of Lord Rockingham 1730-1765 by the late Professor G. H. Guttridge, (1952), and Mr P. Langford's The first Rockingham Administration 1765-66, (1973). Rockingham is perhaps regarded as too colourless a figure to merit either a full-scale biography or an edition of his correspondence, though this view scarcely does his personality justice. For American history of the period and for Whig politics this section of the muniments remains of first class importance.
The film was premiered on 19 December 2017 in Karachi. For The Express Tribune, Rahul Aijaz praised the music, however, rated the film 1.5 stars out of 5, saying "a sad case which delivers on a few fronts but fails by a large margin on major ones, therefore diluting its experience". Shafiq Ul Hasan rated only 1 star out of 5 and wrote, "Rangreza is a tasteless, colourless and soulless failure […] the film simply cannot be categorised under any genre." Sonia Ashraf of DAWN Images too praised the music and some actors, and commented, "while the film was simple," it has "its moments and drawbacks" that "could have been improved with a tighter script and attention to detail".
The back is pinkish-red in colour contrasting with the white belly, from which it is separated by single longitudinal yellow stripe which runs from the operculum to the caudal fin peduncle. The dorsal fins are yellow in colour with 3 parallel red bars while the pectoral fin is a similar colour but lacks markings and the pelvic fin is colourless. The upper lobe of caudal fin is whitish and has 5 or 6 black diagonal bars while the lower lobe is unmarked except for the hind margin which is black as the second bar of the upper lobe extends along it. They can grow to 25 cm but are more usually 10–15 cm.
Like British issues, the stamps could be embossed directly onto a document or on pieces of coloured paper with a cypher label at the back. Initially, colourless embossing was used although later on coloured ink was also used. Embossed adhesives were introduced in 1858, and these were either inscribed IRELAND or were regular British issues but with die letters which were exclusively used in Ireland only. Apart from general duty stamps, there were also directly embossed revenue stamps for Affidavit, Bankers Note or Bill, Bonds, Chancery Fee Fund, Civil Bill Duty, the Court of Bankruptcy and Insolvency, Enrolment, Intermediate Education, Judgements Registry, Law Fund, Lease, Lunacy Fee, Protests, Record of Titles, Registration of Deeds, the Supreme Court of Judicature, and Writ.
The process of plant senescence involves the degradation of chlorophyll: for example the enzyme chlorophyllase () hydrolyses the phytyl sidechain to reverse the reaction in which chlorophylls are biosynthesised from chlorophyllide a or b. Since chlorophyllide a can be converted to chlorophyllide b and the latter can be re-esterified to chlorophyll b, these processes allow cycling between chlorophylls a and b. Moreover, chlorophyll b can be directly reduced (via 71-hydroxychlorophyll a) back to chlorophyll a, completing the cycle. In later stages of senescence, chlorophyllides are converted to a group of colourless tetrapyrroles known as nonfluorescent chlorophyll catabolites (NCC's) with the general structure: :Nonfluorescent chlorophyll catabolites These compounds have also been identified in ripening fruits and they give characteristic autumn colours to deciduous plants.
The move was opposed by Mayor William Dennison along with three of the sitting controllers, but it was passed by a significant majority of council. The Board of Control was replaced with a new executive committee that would be composed of and elected by city council members. The size of city council was expanded by four to retain the same overall number of councillors. William Peyton Hubbard, the son of American slaves who had escaped to Canada through the Underground Railroad, was elected to the first Board of Control in 1904 and served for four terms - he would be he only Black person or person of colour to sit on the body;"City's political class remains mostly colourless", Royson, James.
A carbon monoxide monitor clipped to the uniform of a paramedic Prevention remains a vital public health issue, requiring public education on the safe operation of appliances, heaters, fireplaces, and internal-combustion engines, as well as increased emphasis on the installation of carbon monoxide detectors. Carbon monoxide is tasteless, odourless, and colourless, and therefore can not be detected by visual cues or smell. The United States Consumer Product Safety Commission has stated, "carbon monoxide detectors are as important to home safety as smoke detectors are," and recommends each home have at least one carbon monoxide detector, and preferably one on each level of the building. These devices, which are relatively inexpensive and widely available, are either battery- or AC- powered, with or without battery backup.
Photocatalyst activity indicator inks (Paii's) are a recent advance in the visual demonstration of photocatalysis and the assessment of the activity of photocatalyst materials. They are an inexpensive, easy to use and provide a very quick route to demonstrating the presence of a photocatalytic film, even under low levels of UV light. Unlike the photo-oxidative bleaching of methylene blue, they use the underlying semiconductor photocatalyst film to photoreduce the dye (Dox in figure 2), in the ink coating, to another (usually colourless) form, (Dred in figure 2) whilst simultaneously oxidising an easily oxidised organic species, a sacrificial electron donor (SED), such as glycerol, which is also present in the ink. The kinetics of reduction of the dye in a paii have been studied in great detail.
These are, as usual, followed by complete denials, and assurances that the best feeling exists between the two brothers. The relations of Habibullah Khan with the British government are reportedly of the most friendly nature throughout the year, and he orders his officers on the frontier to prevent all outlaws from British territory from entering Afghanistan. He is reported to have said in durbar that he found by experience that a mild rule was unsuited to the Afghans, and that he has consequently ordered the revival of his father's Secret Intelligence Department. But although the domestic history of Afghanistan during 1902 is comparatively colourless, a very important move is made or attempted by Russia in what may be called its foreign policy.
In December 1891 Julien Viaud (Loti) took command at Hendaye of Javelot, a gunboat charged with watching the French-Spanish border at the mouth of the Bidassoa, an area where smuggling was particularly prevalent. In the first months it appeared to him a colourless place, as his diary of the time indicated, but then its charm worked upon him, to the point where he wanted to buy the house he was renting. He gave it a basque name Bakhar-Etchéa – it became the symbolic opposite of the old family home in Rochefort where his mother and father lived. Loti took command of a gunboat in December 1891, at Hendaye, and the novel Ramuntcho was born of his encounter with the Basque country.
TiCl4 is a dense, colourless distillable liquid, although crude samples may be yellow or even red-brown. It is one of the rare transition metal halides that is a liquid at room temperature, VCl4 being another example. This property reflects the fact that molecules of TiCl4 weakly self-associate. Most metal chlorides are polymers, wherein the chloride atoms bridge between the metals. Its melting and boiling points are similar to those of CCl4. Ti4+ has a "closed" electronic shell, with the same number of electrons as the inert gas argon. The tetrahedral structure for TiCl4 is consistent with its description as a d0 metal center (Ti4+) surrounded by four identical ligands. This configuration leads to highly symmetrical structures, hence the tetrahedral shape of the molecule.
The euphoria of victory did > not remove the foul smell from clogged sewage, and the many beggar women and > children indicated widespread poverty.

The fact that no intensive fighting had taken place in Asmara, could not prevent the city’s utter breakdown. Moreover, the already ruinous state of the city could not be overcome during the course of the war after the dismantling policy of British and Ethiopian occupation.
Crystals from some other localities, notably from in Sardinia, are transparent and colourless, possessed of a brilliant adamantine lustre, and usually modified by numerous bright faces. The variety of combinations and habits presented by the crystals is very extensive, nearly two hundred distinct forms being figured by V. von Lang in his monograph of the species; without measurement of the angles the crystals are frequently difficult to decipher. There are distinct cleavages parallel to the faces of the prism (110) and the basal plane (001), but these are not so well developed as in the isomorphous minerals barite and celestite. Anglesite is a mineral of secondary origin, having been formed by the oxidation of galena in the upper parts of mineral lodes where these have been affected by weathering processes.
However, sodium and potassium form colourless azide salts involving the linear anion; due to the large size of the alkali metal cations, they are thermally stable enough to be able to melt before decomposing. All the alkali metals react readily with phosphorus and arsenic to form phosphides and arsenides with the formula M3Pn (where M represents an alkali metal and Pn represents a pnictogen – phosphorus, arsenic, antimony, or bismuth). This is due to the greater size of the P3− and As3− ions, so that less lattice energy needs to be released for the salts to form. These are not the only phosphides and arsenides of the alkali metals: for example, potassium has nine different known phosphides, with formulae K3P, K4P3, K5P4, KP, K4P6, K3P7, K3P11, KP10.3, and KP15.
It is a colourless alkaline gas with a characteristic pungent smell. The presence of hydrogen bonding has very significant effects on ammonia, conferring on it its high melting (−78 °C) and boiling (−33 °C) points. As a liquid, it is a very good solvent with a high heat of vaporisation (enabling it to be used in vacuum flasks), that also has a low viscosity and electrical conductivity and high dielectric constant, and is less dense than water. However, the hydrogen bonding in NH3 is weaker than that in H2O due to the lower electronegativity of nitrogen compared to oxygen and the presence of only one lone pair in NH3 rather than two in H2O. It is a weak base in aqueous solution (pKb 4.74); its conjugate acid is ammonium, .
According to the Blue Book, this chemical can be systematically named as 1,2,3,4,5,6-hexamethylbenzene. The locants (the numbers in front of the name) are superfluous, however, as the name hexamethylbenzene uniquely identifies a single substance and thus is the formal IUPAC name for the compound. It is an aromatic compound, with six π electrons (satisfying Hückel's rule) delocalised over a cyclic planar system; each of the six ring carbon atoms is sp2 hybridised and displays trigonal planar geometry, while each methyl carbon is tetrahedral with sp3 hybridisation, consistent with the empirical description of its structure. When recrystallised from ethanol, solid hexamethylbenzene occurs as colourless to white crystalline orthorhombic prisms or needles with a melting point of 165–166 °C, a boiling point of 268 °C, and a density of 1.0630 g cm−3.
Critics who dislike the film particularly draw attention to its bleak nature from its opening: complaining that the world of the play does not deteriorate with Lear's suffering, but commences dark, colourless and wintry, leaving, according to Douglas Brode, "Lear, the land, and us with nowhere to go". Cruelty pervades the film, which does not distinguish between the violence of ostensibly good and evil characters, presenting both savagely. Paul Scofield, as Lear, eschews sentimentality: This demanding old man with a coterie of unruly knights provokes audience sympathy for the daughters in the early scenes, and his presentation explicitly rejects the tradition of playing Lear as "poor old white-haired patriarch". Korol Lir has been praised by critic Alexander Anikst for the "serious, deeply thoughtful" even "philosophical approach" of director Grigori Kozintsev and writer Boris Pasternak.
Stanek and Miskovsky (1975) first identified and diagnosed sekaninaite as a new mineral in the cordierite series. They sampled the poorly developed crystals of the Dolni Bory region, Czechoslovakia, where specimen did not exceed 70 cm. Dolni Bory samples are very different from samples found in the Kuznetsk paralavas. They are very close analogues with respect to Mg/Fe ratios but vastly different a-, b- and c- parameters (Grapes, 2010). Grapes and colleagues calculated cell dimension to be a 17.230(5), b 9.835(3), c 9.314(3) A. The colour of sekaninaite is bright blue and distinctly pleochroic with X = colourless; Y = blue; Z = pale blue; absorption occurs in the sequence Y > Z > X. Sekaninaite has a hardness of 7-7.5; it cleaves imperfectly along {100} and exhibits parting on {001} (Fleischer, 1977).
The species can reach a length of . It is similar in appearance to the tropical two-wing flyingfish (Exocoetus volitans) which shares much of its range, but differs in certain characteristics; the head is quite blunt, the forehead sloping steeply down in front of the eyes; the pectoral fins extend as far as the base of the caudal fin; the origin of the anal fin is slightly in front of the origin of the dorsal fin, and the dorsal fin is colourless. Both these two-winged species have very small pelvic fins, whereas other so called four- winged species of flyingfish have pelvic fins that extend at least as far as the origin of the anal fin. Like all flying-fishes, E. obtusirostris exhibits countershading, being darkish blue dorsally and white ventrally.
V2O5 is an amphoteric oxide. Unlike most metal oxides, it dissolves slightly in water to give a pale yellow, acidic solution. Thus V2O5 reacts with strong non-reducing acids to form solutions containing the pale yellow salts containing dioxovanadium(V) centers: :V2O5 \+ 2 HNO3 → 2 VO2(NO3) + H2O It also reacts with strong alkali to form polyoxovanadates, which have a complex structure that depends on pH.. If excess aqueous sodium hydroxide is used, the product is a colourless salt, sodium orthovanadate, Na3VO4. If acid is slowly added to a solution of Na3VO4, the colour gradually deepens through orange to red before brown hydrated V2O5 precipitates around pH 2\. These solutions contain mainly the ions HVO42− and V2O74− between pH 9 and pH 13, but below pH 9 more exotic species such as V4O124− and HV10O285− (decavanadate) predominate.
Greenwood and Earnshaw, pp. 420–4 Over twenty other hydrides of nitrogen are known, the most important being hydrazine (N2H4) and hydrogen azide (HN3). Hydrazine has physical properties that are remarkably similar to those of water: its melting and boiling points are 2.0 °C and 113.5 °C, the density of the solid at −5 °C is 1.146 g/cm3, while that of the liquid at 25 °C is 1.00 g/cm3.Greenwood and Earnshaw, pp. 426–7 The azanes are a series which include ammonia, hydrazine and triazane. Phosphine, a toxic, colourless gas, is the most stable phosphorus hydride and is the first of the homologous straight-chain polyphosphane series PnHn+2 (n = 1–9) that become increasingly thermally unstable as n increases. Other cyclic and condensed polyphosphane series are known, from PnHn to PnHn−18, amounting to 85 known phosphanes in 1997.
The most common type of breaking found in naturally infected plants, called average break, is caused by infection with a mixture of STBV and MTBV; both light breaking and dark breaking symptoms are present, together with some unbroken areas, in different parts of the same petal. Plants infected with a mixture of strains when young may exhibit both effects, with light breaking symptoms restricted to the basal part of the petal and severe dark breaking effects in the upper parts. Some varieties were later found to be incapable of light breaking, and always showed dark breaking symptoms no matter whether infected with STBV or MTBV or a mixture of both strains. Although they still can be infected, white and yellow flowered varieties are incapable of breaking since they lack anthocyanins; their color is determined by colourless or yellow plastids in the mesophyll.
The Dutch Informal Group, preceding the formation of the Nul group, was founded in 1958.Also Dutch artists Fred Sieger (1902-1999) and Rik Jager (1933) participated in exhibitions of the Dutch Informal Group. Bram Bogart (1921-2012) only took part in the very first exhibition, at the refectory of the Delft University, in 1958. Kees van Bohemen (1928-1985) left the group in February 1961. See also: Franck Gribling, Informele Kunst in Belgie en Nederland 1955-'60, exhibit. cat. (The Hague: Gemeentemuseum/Antwerp, Koninklijk Paleis voor Schone Kunsten, 1983), 16. Until early 1961 its members showed works in oils or pigments mixed with plaster and sand, usually on panels, linen or jute. The group replaced the expression of emotions in paint with an attempt at an absence of 'personal signature', resulting in colourless and monochrome works virtually devoid of form or composition.
His biographer Gordon A. Craig claims that this gave few indications of being a gifted writer: "Although the theme of incest, which was to occupy Fontane on later occasions, is touched upon here, the mawkishness of the tale... is equalled by the lameness of its plot and the inertness of the style in which it is told, and [the characters] Clärchen and her brother are both so colourless that no one could have guessed that their creator had a future as a writer."Theodor Fontane: Literature and History in the Bismarck Reich (Oxford University Press, 1999), Fontane's first job as apothecary was in Dresden, after which he worked in his father's shop in the town of Letschin in the Oderbruch region. Fleeing its provincialism, Fontane published articles in the Leipzig newspaper Die Eisenbahn and translated Shakespeare.Wolfgang Hädecke: Theodor Fontane - Biographie.
Friedrich Wöhler, Ordinary Professor of Chemistry at Göttingen University, had coca leaves imported to Germany by Karl von Scherzer, a member of the Austrian Novara expedition, and he gave those leaves to Niemann, his graduate student, to analyze. In 1859, Niemann isolated cocaine from coca leaves. He extracted the primary alkaloid and named the ingredient "cocaine"-as with other alkaloids its name carried the “-ine” suffix (from Latin -ina). He wrote of the alkaloid's “colourless transparent prisms” and said that, “Its solutions have an alkaline reaction, a bitter taste, promote the flow of saliva and leave a peculiar numbness, followed by a sense of cold when applied to the tongue.” He published his finding in 1860 in his dissertation titled Über eine neue organische Base in den Cocablättern (On a New Organic Base in the Coca Leaves).
A historically significant organoplatinum(II) compound is Zeise's salt, which is obtained from ethylene and potassium tetrachloroplatinate: :Synthese Zeise's salt The colourless diolefin complex dichloro(cycloocta-1,5-diene)platinum(II) is a more modern relative, and is more widely used. :dichloro(cycloocta-1,5-diene)platinum(II) The stability and diversity of platinum(II) alkene complexes contrasts with the rarity of alkene complexes of nickel(II). Platinum allyl complexes are also common. In contrast to nickel chemistry, where compounds such as CpNi(L)X are common, cyclopentadienyl derivatives of Pt(II) are rare, consistent with the reluctance of Pt(II) to become pentacoordinate. Alkyl and aryl platinum(II) complexes are often prepared by oxidative addition of an alkyl halide or aryl halide to a Pt(0) precursor such as tetrakis(triphenylphosphine)platinum(0) or Pt(C2H4)(PPh3)2.
However, he goes on to write that 'Dombey and Son is a novel which in its beginning promises more than its progress fulfils' and gives the following reasons why: > Impossible to avoid the reflection that the death of Dombey's son and heir > marks the end of a complete story, that we feel a gap between Chapter XVI > and what comes after (the author speaks of feeling it himself, of his > striving to "transfer the interest to Florence") and that the narrative of > the later part is ill-constructed, often wearisome, sometimes incredible. We > miss Paul, we miss Walter Gay (shadowy young hero though he be); Florence is > too colourless for deep interest, and the second Mrs. Dombey is rather > forced upon us than accepted as a natural figure in the drama. Dickens's > familiar shortcomings are abundantly exemplified.
The French yellow-light mandate was based on observations by the French Academy of Sciences in 1934, when the Academy recorded that the selective yellow light was less dazzling than white light and that the light diffused less in fog than green or blue lights. Yellow light was obtained by dint of yellow glass for the headlight bulb or lens, a yellow coating on a colourless bulb, lens, or reflector, or a yellow filter between the bulb and the lens. Filtration losses reduced the emitted light intensity by about 18 percent, which might have contributed to the reduced glare. The mandate was in effect until December 1992, so for many years yellow headlights visually marked French-registered cars wherever they were seen, though some French drivers are said to have switched to white headlamps despite the requirement for yellow ones.
Charles-François-Prosper Guérin Charles-François-Prosper Guérin (1875 in Sens – 1939) was a French post-impressionist painter. Guérin studied with Gustave Moreau in the l'École des Beaux Arts à Paris, and had one exhibition at the Grafton Galleries in 1910; in a review Huntly Carter wrote of his "daring extravagance" and that he "show[ed] how the strongest primary colours can be used without crudity, and whose work has a decorative value which the average muddy and colourless work of our day does not possess"."Charles François Prosper Guérin (1875 - 1939)", Brown University Guérin attained some historic notoriety for sitting on the jury of the Salon d'Automne of 1908, which rejected almost all of the paintings of Georges Braque. The other jury members were Henri Matisse, Georges Rouault, and Albert Marquet, all of whom had also been students of Moreau.
TJC has been censured by the Advertising Standards Authority the following times since 2007/8 The Jewellery Channel was fined £3,200 by Trading Standards for making false claims about the treatment of a gemstone product sold through its TV channel. After complaints were made, the channel discovered that it had been selling jewellery described as natural 'pink topaz’, when in fact it was colourless topaz sprayed pink. Auction date, 25 August 2013: The ASA received a complaint as to whether an auction starting price was misleading and exaggerated the item's value. Although the Jewellery Channel attributes no worth or value to the starting price, the ASA upheld the complaint on the grounds that, in this case, most viewers would infer that the opening figure represented a genuine valuation of the ring, and therefore the final reduced price was a genuine saving.
The raw material for producing kala namak was originally obtained from natural halite from mines in Northern India and Pakistan in certain locations of the Himalayas salt ranges, or from salt harvested from the North Indian salt lakes of Sambhar or Didwana. Traditionally, the salt was transformed from its relatively colourless raw natural forms into the dark coloured commercially sold kala namak through a reductive chemical process that transforms some of the naturally occurring sodium sulfate of the raw salt into pungent hydrogen sulfide and sodium sulfide. This involves firing the raw salts in a kiln or furnace for 24 hours while sealed in a ceramic jar with charcoal along with small quantities of harad seeds, amla, bahera, babul bark, or natron. The fired salt melts, the chemical reaction occurs, and the salt is then cooled, stored, and aged prior to sale.
The Folin–Wu and the Somogyi–Nelson methods are both based on the same principles. In the first step, glucose (or a reducing sugar) is oxidised using a solution of Cu(II) ion, which is reduced to Cu(I) by the process. In the second step, the Cu(I) ions are then oxidised back to Cu(II) using a colourless hetero-polymolybdate complex, which is, in the process, reduced to give the characteristic blue colour. Finally the absorption of the hetero-poly molybdenum blue is measured using a colorimeter and compared to standards prepared from reacting sugar solutions of known concentration, to determine the amount of reducing-sugar present. The Folin–Wu method "A system of blood analysis" O. Folin, H. Wu, The Journal of Biological Chemistry (1920), 41(3), 367 uses a reagent that contains sodium tungstate.
In most commercial photocatalytic products the active layer is a thin, clear, colourless coating of the semiconductor anatase titania, which requires UV light to photogenerate the necessary electrons (e−) and holes (h+), in its conductance and valence bands, respectively, to promote the photocatalytic process.V. Augugliaro, V. Loddo, M. Pagliaro, G. Palmisano, L. Palmisano, "Clean by Light Irradiation: Practical Applications of Supported TiO2", RSC Publishing, Cambridge, 2010. A schematic of the key processes behind the photocatalytic mineralisation of an organic pollutant on the surface of a titania photocatalyst film is illustrated in figure 1 and the overall reaction is summarised by: Reaction Summary (1) Water molecules—adsorbed to the photocatalyst—are also needed to generate the hydroxyl groups on the surface. The marketing of photocatalytic products and prevention of counterfeiting is made difficult because the photocatalytic coatings are usually and necessarily invisible to the eye.
In this book Newton sets forth in full his experiments, first reported to the Royal Society of London in 1672, on dispersion, or the separation of light into a spectrum of its component colours. He demonstrates how the appearance of color arises from selective absorption, reflection, or transmission of the various component parts of the incident light. The major significance of Newton's work is that it overturned the dogma, attributed to Aristotle or Theophrastus and accepted by scholars in Newton's time, that "pure" light (such as the light attributed to the Sun) is fundamentally white or colourless, and is altered into color by mixture with darkness caused by interactions with matter. Newton showed just the opposite was true: light is composed of different spectral hues (he describes seven — red, orange, yellow, green, blue, indigo and violet), and all colours, including white, are formed by various mixtures of these hues.
Fingerprint evidence for an Aum member linked to an earlier kidnapping, in addition to the sarin-contaminated soil samples, caused the police to set a raid date for 22 March. Asahara was made aware of the impending raid by two cult members inside the Self-Defense Forces, and ordered an attack on Tokyo subway lines close to the Metropolitan Police Department on the morning of the 20th March – possibly as a desperate attack to initiate the apocalypse. To aid in this, Tsuchiya was ordered by Endo to produce sarin again on 18 March - due to a lack of normal precursors as a result of the chemical destruction process, the sarin produced was of a lower quality and caused the normally colourless sarin to appear brown. 30 kg of the chemical was manufactured and stored in a large container, from which it was decanted into plastic bags.
In July 2004, a BBC Business News article referred to how "colourless versions" of Coke "have not been hugely successful".Bananas are not the only fruit BBC NEWS / BUSINESS - 1 July 2004 Some have even referred to Tab Clear's marketing as a "born to die" campaign.Sport marketing, Volume 13 Google Books UK In his 2011 book, Killing Giants: 10 Strategies to Topple the Goliath in Your Industry, Stephen Denny published an interview with former Coca-Cola Chief Marketing Officer Sergio Zyman that stated the formation and subsequent failure of Tab Clear was a deliberate move to destroy Crystal Pepsi, capitalizing on the public's lack of understanding of Pepsi's heavily marketed product. Tab Clear was marketed as a diet drink, which were less popular than traditional colas, and the Tab brand in general was seen as an inferior product to flagships like Coca-Cola or Pepsi.
Many general purpose vectors such as pUC19 usually include a system for detecting the presence of a cloned DNA fragment, based on the loss of an easily scored phenotype. The most widely used is the gene coding for E. coli β-galactosidase, whose activity can easily be detected by the ability of the enzyme it encodes to hydrolyze the soluble, colourless substrate X-gal (5-bromo-4-chloro-3-indolyl-beta-d-galactoside) into an insoluble, blue product (5,5'-dibromo-4,4'-dichloro indigo). Cloning a fragment of DNA within the vector-based lacZα sequence of the β-galactosidase prevents the production of an active enzyme. If X-gal is included in the selective agar plates, transformant colonies are generally blue in the case of a vector with no inserted DNA and white in the case of a vector containing a fragment of cloned DNA.
The activation of H2 using FLPs was first reported in 2006. In this report a phosphonium-borate species was observed to undergo the thermal loss of a H2 molecule, to generate the phosphine and the borane. The phosphonium- borate species 1 was prepared from B(C6F5)3 and (C6H2Me3)2PH, due to the steric demands of both of these molecules a traditional adduct could not be formed and the zwitterionic phosphonic-boronate was prepared [Figure 1]. A “H-for-F exchange” was carried out to give 2 which was stable to moisture and air. This salt will release molecular H2 when heated above 100 °C, a colour change was also observed from the colourless 2 to the orange-red 3 (both in THF). This reaction is reversed by reacting 3 with H2 at 25 ℃ where the colour change is reversed and 2 is reformed.
Detail of the Monstrance's supporting base, showing the figures of Faith, Hope and Charity A monstrance functions as a vessel to present the consecrated host to the congregation as pert of the Roman Catholic liturgical ritual of Eucharistic adoration. A typical monstrance in form, the highly ornate Bemposta Monstrance comprises a sunburst framing the circular frame for the wafer (which has a curved holder set with stones that holds it up to view, its shape echoing the crescent moon that is usually depicted at the foot of Virgin Mary when evoking the Immaculate Conception) supported on an undulating stem that stands upon an intricately sculpted supporting base. The base is set with figures symbolising the three theological virtues (Faith, Hope and Charity) below angels with the symbols of the Eucharist, flanking narrative medallions showing scenes from the Passion cycle. It is made of gilt silver, and set with numerous stones: diamonds, rubies, emeralds, sapphires, amethysts, chrysoberyls, topaz (colourless, Imperial, and pink).
Its properties are mostly intermediate between those of chlorine and fluorine. It will react with many metals and nonmetals from room temperature and above, fluorinating them and liberating chlorine. It will also act as a chlorofluorinating agent, adding chlorine and fluorine across a multiple bond or by oxidation: for example, it will attack carbon monoxide to form carbonyl chlorofluoride, COFCl. It will react analogously with hexafluoroacetone, (CF3)2CO, with a potassium fluoride catalyst to produce heptafluoroisopropyl hypochlorite, (CF3)2CFOCl; with nitriles RCN to produce RCF2NCl2; and with the sulfur oxides SO2 and SO3 to produce ClOSO2F and ClSO2F respectively. It will also react exothermically and violently with compounds containing –OH and –NH groups, such as water: :H2O + 2 ClF ⟶ 2 HF + Cl2O Chlorine trifluoride (ClF3) is a volatile colourless molecular liquid which melts at −76.3 °C and boils at 11.8 °C. It may be formed by directly fluorinating gaseous chlorine or chlorine monofluoride at 200–300 °C.
Triphenyl phosphite is the chemical compound with the formula P(OC6H5)3. This colourless viscous liquid is the ester of phosphorous acid and phenol. It is used as a ligand in organometallic chemistry. Nickel complexes of this ligand are homogeneous catalysts for the hydrocyanation of alkenes. Triphenylphosphite is prepared from phosphorus trichloride and phenol in the presence of a base: :PCl3 \+ 3 HOC6H5 → P(OC6H5)3 \+ 3 HCl Trimethylphosphine is prepared from triphenylphosphite:Leutkens, Jr., M. L.; Sattelberger, A. P.; Murray, H. H.; Basil, J. D.; Fackler, Jr., J. P. "Trimethylphosphine" Inorganic Syntheses, 1990, volume 28, pages 305-310. : 3 CH3MgBr + P(OC6H5)3 → P(CH3)3 \+ 3 MgBrOC6H5 Triphenylphosphite is a notable example of polyamorphism in organic compounds, namely it exists in two different amorphous forms at temperatures about 200 K. Not long ago a new long-awaited polymorphic modification of triphenyl phosphite was obtained by means of crystallization in ionic liquidsD.
Tovar, Rui. p. 598 Porto won 1–0 through Deco's goal, in a match that Manuel Queiroz at Record defined as " ... ending the last doubts of who is the future champion and who is the best team in the league, defeating Camacho's Benfica for the first time ...

55 In 1677, when the Grand Duke arranged to get his antique sculptures released from Rome, Ercole Ferrata was recalled to Florence to unpack and see to them. "A rather colourless, plodding sculptor whose gifts were best displayed in executing or imitating the conceptions of more imaginative artists, Ferrata nonetheless enjoyed a deserved reputation as an authority on the antique".Haskell & Penny 1981:57 When a headless torso had been discovered a few years previously, during the opening of a new road to the Santa Maria in Vallicella, the order of the Oratorians who owned the torso sent it to be "restored" by Ercole Ferrata, who essentially created the Faun Carrying a Kid, which after purchase by Queen Christina, was sold in 1724 to Philip V of Spain.Today in the Prado Ferrata is less known for the documented fact that he provided the elegant arms for the Venus de' Medici.Haskell & Penny 1981:326.
The development of this large-scale industry is not fully understood, but Pliny's Natural History (36, 194), in addition to evidence for the first use of molten glass in the mid-1st century AD, indicates that furnace technologies experienced marked development during the early-to-mid-1st century AD, in tandem with the expansion of glass production. The siting of glass-making workshops was governed by three primary factors: the availability of fuel which was needed in large quantities, sources of sand which represented the major constituent of the glass, and natron to act as a flux. Roman glass relied on natron from Wadi El Natrun, and as a result it is thought that glass-making workshops during the Roman period may have been confined to near-coastal regions of the eastern Mediterranean. This facilitated the trade in the raw colourless or naturally coloured glass which they produced, which reached glass-working sites across the Roman empire.
Despite his PhD in organo- fluorine chemistry he switched focus by 1970 to look more at polymer chemistry, specifically polymer synthesis after he had experimented with fluorinated diene monomers and 'found it fascinating that you could take a mobile, colourless fluid and produce a material that had potentially interesting properties.' He helped develop what is now known as the "Durham precursor route" to manufacturing polyacetylene, and during the 70s and 80s the polymer synthesis knowledge of Feast and his group led to invitations to work as a guest lecturer, and eventually he spent two months a year teaching at the Max Planck Institute for Polymer Research in Mainz. During his time at Durham Feast was promoted up the academic ranks, rising from lecturer to senior lecturer in 1965 and professor in 1986. In 1996 he was made a Fellow of the Royal Society, and in 2006 was elected President for two years of the Royal Society of Chemistry.
Tin(IV) bromide is the chemical compound SnBr4. It is a colourless low melting solid. SnBr4 can be prepared by reaction of the elements at normal temperatures:Egon Wiberg, Arnold Frederick Holleman (2001) Inorganic Chemistry, Elsevier :Sn + 2Br2 → SnBr4 In aqueous solution Sn(H2O)64+ is the principal ionic species amongst a range of 6 coordinate ions with from 0-6 bromide ligands (e.g. Sn(H2O)64+, SnBr(H2O)53+)Sn NMR and vibrational spectroscopy, Taylor M.

In The Mystical Qabalah Dion Fortune describes Keter as pure consciousness, beyond all categories, timeless, a point that crystallises out of the Ein Soph, and commences the process of emanation that ends in Malkuth. The name of God given to it is Eheieh, the archangel that presides over it is Metatron, the order of angels that resides in it are the Holy Living Creatures (the Chaioth ha Qadesh, Hebrew: חיות הקדש), and its mundane chakra is said to be the First Swirlings of the cosmos (Primum Mobile, Rashith ha Gilgalin). A.E. Waite made mention that Rabbi Azariel ben Menachem, a student of Isaac the Blind, in his Commentary on the Sephiroth granted a particular colour to each Sephira, yet these do not agree with the colours given in the Zohar, where Kether (which, according to him, is also correlated to Yechidah) is called colourless, Tiphareth purple, and Malkuth sapphire- blue.A.E. Waite, The Holy Kabbalah As pure formless consciousness, it is often compared with the Sahasrara chakra, which resides above the crown of the head, in Indian Shakta Tantra.
The same technology used in cutting the future Golden Jubilee diamond was later used in the cutting of the Centenary Diamond, a smaller (273.85 carats) flawless and colorless rough diamond. Gabriel Tolkowsky was hired by De Beers to cut the diamond and also so he could test special tools and cutting methods that were being developed for use on the colourless D-colour Centenary. Because of its cracks and inclusions, it was decided by De Beers and Gabriel Tolkowsky to construct an underground room that was free from vibration before work could begin on the diamond. In 1990, after two years of work, the stone was finished, reduced in total from 755.50 carats, to 545.65 carats. Gabi Tolkowsky described the cut as a “Fire-Rose cushion shape.” Golden Jubilee De Beers Group The unnamed diamond was brought to Thailand by the Thai Diamond Manufacturers Association to be exhibited in the Thai Board of Investment Exhibition in Laem Chabang and was selected to herald De Beer's centennial celebrations in 1988.
Against what he describes as "the well-behaved writing of revolutionaries", Barthes praises the work of writers who "create a colourless writing, freed from all bondage to a pre-ordained state of language". Barthes credits Albert Camus with the initiation of this "transparent form of speech", specifically Camus' 1942 novel The Stranger. However, Barthes also praises the novelist and poet Raymond Queneau for allowing the patterns of spoken speech in his fiction to "contaminate all the parts of the written discourse", as against Jean-Paul Sartre, in whose novels only the spoken dialogue resembled spoken language, with the result that naturalness of the dialogue in Sartre's novels resembled "arias, so to speak, surrounded by long recitatives in an entirely conventional mode of writing". Barthes ends the book on a literally Utopian note: > Feeling permanently guilty of its own solitute, it [literary writing] is > none the less an imagination eagerly desiring a felicity [bonheur] of words, > it hastens towards a dreamed-of language whose freshness, by a kind of ideal > anticipation, might portray the perfection of some Adamic world where > language would no longer be alienated.
However, as Rot Lop Fan's species had evolved in darkness, they had no concept of light and color, and thus Katma Tui was unable to explain how the power ring worked (it projects solid rays of light manifested by the bearer's will power). Realizing that his species operates by hearing, Katma coaches him to create a hand bell with the ring, and describes the Green Lantern Corps as the "F-Sharp Bell Corps" — "F-Sharp" being a reassuring note for Rot Lop Fan's race in the same manner that green is a reassuring color, and the ring's powers in terms of sound instead of light. She also composes a new oath for him to recite: :In loudest din or hush profound :my ears hear evil's slightest sound :let those who toll out evil's knell :beware my power, the F-Sharp Bell! Having solved this dilemma, Katma leaves Rot Lop Fan to protect his people, not mentioning the ring's weakness to yellow as the colourless space made it relatively pointless; although, she privately notes that in some ways, Rot Lop Fan cannot be counted as a member of the "Green Lantern" Corps as he has truthfully never heard of them.
Kingsley wrote two books about her experiences: Travels in West Africa (1897), which was an immediate best-seller, and West African Studies (1899), both of which gained her respect and prestige within the scholarly community. Some newspapers, however, such as the Times under colonial editor Flora Shaw, refused to publish reviews of her works. Though some argue this is likely on the grounds that her beliefs countered the imperialistic intentions of the British Empire and the notion that Africans were inferior peoples, this is unlikely to explain her sometimes unfavorable reception, because she did support British traders and British indirect rule in Africa,. The notable success of Travels in West Africa was due in no small part to the vigour and droll humour of writing, that, in the guise of a ripping yarn, never wavers from its true purpose – to complete the work her father had left undone. Between poles of manifest wit and latent analysis Kingsley constructs in images – "… not an artist’s picture, but a photograph, an overladen with detail, colourless version" – a discourse of poetic thought; a phenomenon oft- noted in the texts of Walter Benjamin.
The simplest compound of bromine is hydrogen bromide, HBr. It is mainly used in the production of inorganic bromides and alkyl bromides, and as a catalyst for many reactions in organic chemistry. Industrially, it is mainly produced by the reaction of hydrogen gas with bromine gas at 200–400 °C with a platinum catalyst. However, reduction of bromine with red phosphorus is a more practical way to produce hydrogen bromide in the laboratory:Greenwood and Earnshaw, pp. 809–12 : 2 P + 6 H2O + 3 Br2 → 6 HBr + 2 H3PO3 : H3PO3 \+ H2O + Br2 → 2 HBr + H3PO4 At room temperature, hydrogen bromide is a colourless gas, like all the hydrogen halides apart from hydrogen fluoride, since hydrogen cannot form strong hydrogen bonds to the large and only mildly electronegative bromine atom; however, weak hydrogen bonding is present in solid crystalline hydrogen bromide at low temperatures, similar to the hydrogen fluoride structure, before disorder begins to prevail as the temperature is raised. Aqueous hydrogen bromide is known as hydrobromic acid, which is a strong acid (pKa = −9) because the hydrogen bonds to bromine are too weak to inhibit dissociation.

On 8 June 1798 he was among nine provincial actors who appeared in a benefit for five of them. Twaits played Glenalvon in Douglas and Tom Tug in The Waterman and also sang between the acts. On 17 May 1799 Twaits and some of the actors from June 1789 were back at Wheatley's in Greenwich where they performed She Stoops to Conquer (during which Twaits as Tony Lumpkin sang "a song in character") and The Agreeable Surprise.
Klare, the son of Indian parents who migrated to Britain in the 1960s, had suggested collecting money for Griffin to be deported to the South Pole, as "it's a colourless landscape that will suit you fine". Klare said that while he did not think so at first, in retrospect he thought that Question Time was the right platform for Griffin. Analysing the broadcast footage, The Times determined that the cameras spent "nearly 25 minutes" of the hour-long programme of the screen time either on Griffin or a "two-shot" with him and another panellist, equating to 38%. The Daily Mail alleged that the BBC "stage-managed" the programme, highlighting a crib-sheet handed out to the audience members; The Guardians 'Media Monkey' blog observed that such a sheet is routinely given to the audience, and also accused The Mail of using a 'doctored' crib-sheet. The first opinion poll taken after Nick Griffin's appearance, conducted hours after the programme by YouGov for The Daily Telegraph, indicated that voter support for the BNP had increased by 1%, from 2% to 3%, in the previous month, and that 22% of voters were now "seriously considering" voting BNP in a future local, general or European election — broken down into "definitely", 4%; "probably", 3%; and "possible", 15%.
