When the ammonia is taken up by plants, it is used to synthesise proteins. These plants are then digested by animals who use the nitrogen compounds to synthesise their own proteins and excrete nitrogen–bearing waste. Finally, these organisms die and decompose, undergoing bacterial and environmental oxidation and denitrification, returning free dinitrogen to the atmosphere. Industrial nitrogen fixation by the Haber process is mostly used as fertiliser, although excess nitrogen–bearing waste, when leached, leads to eutrophication of freshwater and the creation of marine dead zones, as nitrogen-driven bacterial growth depletes water oxygen to the point that all higher organisms die.

In contrast, stem-branches and leaves are exogenous, i.e., they start to develop from the cortex, an outer layer. In response to the concentration of nutrients, roots also synthesise cytokinin, which acts as a signal as to how fast the shoots can grow. Roots often function in storage of food and nutrients.
Harradence wrote hers, under Robinson's supervision, on the "Synthesis of cyclic ketones related to the sex hormones" at Somerville College. Robinson had Harradence and Cornforth synthesise penicillamine. They became engaged in 1941, and were married in the September of that year. They would have a son, John, and two daughters, Brenda and Philippa.
They can travel significant distances each night, exceptionally as much as in the spotted bat (Euderma maculatum), in search of food. Bats use a variety of hunting strategies. Bats get most of their water from the food they eat; many species also drink from water sources like lakes and streams, flying over the surface and dipping their tongues into the water. The Chiroptera as a whole are in the process of losing the ability to synthesise vitamin C. In a test of 34 bat species from six major families, including major insect- and fruit- eating bat families, all were found to have lost the ability to synthesise it, and this loss may derive from a common bat ancestor, as a single mutation.
These are the only animal viruses within the order Mononegavirales to do this. Many plant rhabdoviruses replicate in the nucleus. Bornaviruses have negative sense RNA genomes The negative sense RNA is copied to make a positive sense RNA template. This template is then used to synthesise many copies of the negative sense RNA genome.
In the course of an organic synthesis, a chemist often needs to form a new or alter an existing ring. Ring expansion and ring contraction reactions are used to expand or contract an existing ring, often making it possible to access structures that would be difficult if not impossible to synthesise with single cyclization reactions.
They are more reactive than the likewise organotins and can therefore be used to synthesise sterically crowded biaryls. In oxyplumbation, organolead alkoxides are added to polar alkenes: :H2C=CH-CN + (Et3PbOMe)n → MeO-CH2-HC(PbEt3)-CN → MeO-CH2-CH2-CN The alkoxide is regenerated in the subsequent methanolysis and, therefore, acts as a catalyst.
ZnO nanostructures have found uses in environmental, technological and biomedical purposes including dye-sensitised solar cells, lithium-ion batteries, biosensors, nanolasers and supercapacitors. Research is ongoing to synthesise more productive and successful nanostructures from ZnO and other composites.

The majority of PtdIns3P appears to be constitutively synthesised by the class III PI 3-kinase, PIK3C3 (Vps34), at endocytic membranes. Class II PI 3-kinases also appear to synthesise PtdIns3P, their activity however appears to be regulated by a range of stimuli, including growth factors. This suggests that specific pools of PtdIns3P may be synthesised upon cell stimulation.
He was known for his ability to synthesise existing legal scholarship but made few original contributions or investigations. He published little aside from book reviews from the mid-1920s. After leaving Cambridge, he lived out the remainder of his life in the United States, with an office at Harvard Law School. He died on 23 January 1960.
Steric effects make triisopropylamine difficult to synthesise and unlike less hindered tertiary amines (such as triethylamine) it cannot be produced by the alkylation of ammonia with alcohol; attempts to do so stall at diisopropylamine. It can be prepared from diisopropylamine on the laboratory scale: :500px Industrial synthesis involves the reaction of ammonia with propylene oxide followed by hydrogenation.
Paul Nikolaevich Evdokimov () (August 2 [O.S. July 20], 1901 – September 16, 1970) was an Orthodox Christian theologian, professor at the St. Sergius Orthodox Theological Institute, and émigré. Paul Evdokimov's theological thought is marked by the attempt to synthesise two important currents in 20th century Orthodox thought, namely the "neo-patristic" renewal and the insights of the Russian religious philosophers.
GnTV is the enzyme required to synthesise polylactosamine chains, which are the ligand for galectin-3 on T cell receptors. This knock-out means galectin-3 cannot prevent auto-activation of TCR so T cells are hypersensitive. Also within the immune system, galectins have been proven to act as chemoattractants to immune cells and activate secretion of inflammatory cytokines.
It is also possible to synthesise heterocyclic compounds via the Elbs reaction. In 1956 an Elbs reaction of a thiophene derivative was published. The expected linear product was not obtained due to a change in reaction mechanism after formation of the first intermediate which caused multiple free radical reaction steps.G. M. Badger, B. J. Christie. (1956).
Case and Swanson 1989 Students sitting this test item format have a greater chance of answering incorrectly if they cannot synthesise and apply their knowledge as shown through the work of Susan Case and David Swanson (1989). Evidence suggests that this format works best when there is a single best answer to each successive scenario or vignette.
Speculative pathways for NAADP synthesis and degradation. ADP-ribosyl cyclase (ARC) family members (such as CD38) can synthesise NAADP via the base-exchange reaction (NicAcid, Nicotinic Acid; NiAm, nicotinamide). NAADP may be broken down to NAAD via a Ca2+-sensitive phosphatase, or to 2-phosphoadenosine diphosphoribose (ADPRP) by CD38 itself. For simplicity, enzyme topology has been ignored (see below).
Instead, the animals may synthesise the pigments from precursors such as the amino acid tyrosine. Nevertheless, this natural sunscreen cannot prevent the animal's skin from cracking if it stays out of water too long. The secretion does help regulate the body temperature of the hippo and acts an antibiotic source. A hippo's lifespan is typically 40–50 years.
These relatively simple molecules may be then used to further synthesise more complicated molecules, including proteins, complex carbohydrates, lipids, and nucleic acids, or be respired to perform work. Consumption of primary producers by heterotrophic organisms, such as animals, then transfers these organic molecules (and the energy stored within them) up the food web, fueling all of the Earth's living systems.
Melanosomes are dependent for their pigment on certain enzymes, especially tyrosinase, that synthesise the large polymers of melanin within the cell. Before it generates sufficient pigment to be seen on light microscopy it is known as a pre-melanosome. Dysfunction or absence of the melanin-synthesising enzymes (in conditions such as Chédiak–Higashi syndrome) leads to various patterns of albinism.
Two proglottids of Taenia solium. This species has 7 to 13 branches of the uterus on each side (above and below in this micrograph). Once anchored to the host's intestinal wall, tapeworms absorb nutrients through their surface as their food flows past them. Cestodes are unable to synthesise lipids, which they use for reproduction, and are therefore entirely dependent on their hosts.
In 1844, the French chemist Adolphe Wurtz synthesised copper hydride for the first time.Wurtz, A. (1844) "Sur l'hydrure de cuivre" (On copper hydride), Comptes rendus, 18 : 702–704. This reaction consisted of the reduction of copper sulfate with hypophosphorous acid (H3PO2). In 2011, Panitat Hasin and Yiying Wu were the first to synthesise a metal hydride (copper hydride) using the technique of sonication.
Everolimus has O-2 hydroxyethyl chain substitution and deforolimus has a phosphine oxide substitution at position C-43 in the lactone ring of rapamycin. Deforolimus (Ridaforolimus ) has C43 secondary alcohol moiety of the cyclohexyl group of Rapamycin that was substituted with phosphonate and phosphinate groups, preventing the high- affinity binding to mTOR and FKBP. Computational modelling studies helped the synthesise of the compound.
Laureates receive a heavily decorated diploma together with a gold medal and the prize money. Here Fritz Haber's diploma is shown, which he received for the development of a method to synthesise ammonia. All medals made before 1980 were struck in 23 carat gold. Since then, they have been struck in 18 carat green gold plated with 24 carat gold.
He was the first to synthesise uric acid from glycine in 1882. He also noticed that aminoacids were building blocks of proteins. Horbachevsky worked in Austria, Czechoslovakia, Hungary and Ukraine. It was as though the Dual Monarchy was responding to the Spanish flu when, on 30 July 1918, Imperial Councillor Ivan Horbachevsky was appointed by imperial decree the empire’s first health minister.
DDQ and an acid catalyst has been used to synthesise a steroid with a phenanthrene core by oxidation accompanied by a double methyl migration. In the process, DDQ is itself reduced into an aromatic hydroquinone product. :center Sulfur and selenium are traditionally used in aromatization, the leaving group being hydrogen sulfide. Soluble transition metal complexes can induce oxidative aromatization concomitant with complexation.
When General Electric moved from California to Milwaukee, Ferrara returned to academia. She was a master's student at California State University, Sacramento, where she used microprocessors to synthesise speech. Ferrara moved to the University of California, Davis for her gradaute research, where she developed ultrasound methods to measure blood velocity. After graduating she worked as an associate professor at the California State University, Sacramento.
The bacteria synthesise amino acids, vitamins, and haem for the protozoan. In return the protozoan offers its enzymes for the complete metabolic pathways for the biosysnthesis of amino acids, lipids and nucleotides, that are absent in the bacterium. Phosphatidylinositol, a membrane lipid required for cell-cell interaction, in the bacteria is also synthesised by the protozoan. Thus the two organisms intimately share and exchange their metabolic systems.
After her PhD, Thanh was a postdoctoral researcher at Aston University, where she worked on medicinal chemistry. She developed a technique that could be used to synthesise cell membrane permeable fluorescent versions of cyclic adenosine monophosphate (cAMP) and cyclic guanosine monophosphate (cGMP). Thanh moved to the University of New Orleans in 2001, where she began to work with nanotechnology. Here she developed nanoparticle sensors for biological assays.
Qilin Culture's modern management theory, based on the traditional yin—yang and five-elements cosmology, was the basis for the Zhong Gong organisation, according to Palmer.Palmer (2007), p. 83 It was claimed to be applicable to family, business or government, and aimed to synthesise the best aspects of the five phases of human social development: primitive society, slave society, feudal society, capitalist society and communist society.
Rao is one of the world's foremost solid state and materials chemists. He has contributed to the development of the field over five decades. His work on transition metal oxides has led to basic understanding of novel phenomena and the relationship between materials properties and the structural chemistry of these materials. Rao was one of the earliest to synthesise two-dimensional oxide materials such as La2CuO4.
He was one the first to synthesise 123 cuprate, the first liquid nitrogen-temperature superconductor in 1987. He was also the first to synthesis Y junction carbon nanotubes in the mid-1990s. His work has led to a systematic study of compositionally controlled metal-insulator transitions. Such studies have had a profound impact in application fields such as colossal magneto resistance and high temperature superconductivity.
November 2001 Another criticism is that the whirling dancers he uses to accompany his shows do not accurately display the correct dervish routines. However, as more than a ney player, working just as often as a DJ as performing live in concert, with an audience consisting of clubbers, not Islamic scholars, Dede aims to synthesise several different traditions rather than recreate a historically pure music.
The National-Social Association (, NSV) was a political party in the German Empire, founded in 1896 by Friedrich Naumann. It sought to synthesise liberalism, nationalism and non-Marxist socialism with Protestant Christian values in order to cross the ideological front lines and draw workers away from Marxist class struggle. However, it never grew beyond a minor party of intellectuals which failed to gain mass support in elections..
Article on "Freund, August" in: Österreichisches Biographisches Lexikon 1815-1950 Online- EditionOn-line museum of Kęty, Poland (in Polish). In 1881 he discovered a method for synthesising cyclopropane: he treated 1,3 - dibromopropane with sodium metal. The method now bears his name. He was able to synthesise enough cyclopropane to do several chemical reactions and derive from the results the three-membered ring structure of cyclopropane.
Square waves sound harsh and contain harmonics which can cause problems in analysis so these are filtered out where possible. Some recent all-digital detectors can synthesise a sine wave instead of a square wave. One example of a detector which synthesises a sine-wave FD output is the Griffin. Some FD detectors output this constant level signal which renders background noise and bat calls at the same high level.
Fructans are important storage polysaccharides in the stems of many species of grasses and confer a degree of freezing tolerance. A notable exception is rice, which is unable to synthesise fructans. In barley, fructan accumulates in the cell vacuoles and acts as a carbon sink within the cell to facilitate photosynthesis. Fructan reserves are transported to the reproductive tissue during grain filling, and to the vegetative tissues during periods of growth.
This technology is now being used to investigate novel vaccine strategies. The ability to synthesise viruses has far-reaching consequences, since viruses can no longer be regarded as extinct, as long as the information of their genome sequence is known and permissive cells are available. , the full-length genome sequences of 7454 different viruses, including smallpox, are publicly available in an online database maintained by the National Institutes of Health.
Pictures on Exhibit said: There are very few artists of today's generation with the ability to synthesise the quality of 20th Century Ecole de l'Europe in the sense that the late impressionists and the post-impressionists did it for their epoch. Alfred Cohen is one of them, and maybe this explains his success with a wide category of collectors. Their enthusiasm is unstinting . . . . These are recognizably contemporary paintings.
Some species of aphids have acquired the ability to synthesise red carotenoids by horizontal gene transfer from fungi. They are the only animals other than two-spotted spider mites and the oriental hornet with this capability. Using their carotenoids, aphids may well be able to absorb solar energy and convert it to a form that their cells can use, ATP. This is the only known example of photoheterotrophy in animals.
Ernest Gellner, Encounters with Nationalism, Basil Blackwell, 1994 p.157 He once said in an interview that since childhood he had tried fervently 'to synthesise the cultures of the northern shore of the Mediterranean with those of its southern shore'. Berque's most lasting contribution might have been to the study of Islam. A devout Christian, he found in Islam "a new version of the truth of the world".
Another method to synthesise ZnO nanostructures is electrodeposition, which uses electric current to facilitate chemical reactions and deposition on electrodes. Its low temperature and ability to create precise thickness structures makes it a cost-effective and environmentally friendly method. Structured nanocolumnar crystals, porous films, thin films and aligned wires have been synthesised in this way. The quality and size of these structures depends on substrates, current density, deposition time and temperature.
Véronique Gouverneur (born 8 November 1964) is a professor of chemistry at the University of Oxford in the United Kingdom. Her specialism is the chemistry of fluorine, and her research involves finding new ways to synthesise organic fluorine compounds. She leads a research group at the University and, in addition to her chair, also holds a tutorial fellowship at Merton College, Oxford. Her research has received multiple professional and scholarly awards.
In order to synthesise and test theoretical understanding of atmospheric chemistry, computer models (such as chemical transport models) are used. Numerical models solve the differential equations governing the concentrations of chemicals in the atmosphere. They can be very simple or very complicated. One common trade off in numerical models is between the number of chemical compounds and chemical reactions modeled versus the representation of transport and mixing in the atmosphere.
Diarylquinolines (DARQs) are a chemical class of drugs that treat tuberculosis. They target subunit c of mycobacterial ATP synthase, inhibiting the enzyme so mycobacterium tuberculosis cannot synthesise ATP. This effectively kills the bacteria. Although ATP synthase in bacteria is similar to its eukaryotic analogue, diarylquinoline agents (such as TMC207) are very specific to the bacterial enzyme, so were expected to be safe for use in humans and other eukaryotes.
He was author of more than 200 scientific publication, among which were 4 monographs. Among his pupils are three doctors and 25 holders of PhD of science. S. V. Goldin possesses among others, the theory of the seismic migration allowing quantitatively to compare various algorithms of construction of the plotting of medium and to synthesise algorithms with set properties.S. V. Goldin Seismic traveltime inversion: Investigations in geophysics. SEG, Tulsa, 1986, Vol.1.
Frequency division: Original signal is converted into square waves and then divided by a fixed factor (here: 16). Frequency division (FD) bat detectors synthesise a sound which is a fraction of the bat call frequencies, typically 1/10. This is done by converting the call into a square wave, otherwise called a zero crossing signal. This square wave is then divided using an electronic counter by 10 to provide another square wave.
Despite little production at the end of his career he had an important and fundamental impact on the artistic panorama of Bolognese art at the start of the 20th century. He participated at international exhibitions, like the ones in Bologna 1888 and Milano 1906. His impact continued to the middle of the century due to his ability to analyse, personalise, and synthesise the artistic trends that were present in Europe at the time.
For the purpose of this article, lysine will refer to the biologically active enantiomer L-lysine, where the α-carbon is in the S configuration. The human body cannot synthesize lysine. It is essential in humans and must be obtained from the diet. In organisms that synthesise lysine, it has two main biosynthetic pathways, the diaminopimelate and α-aminoadipate pathways, which employ distinct enzymes and substrates and are found in diverse organisms.
Single strand of artificial spider silk produced under laboratory conditions To artificially synthesise spider silk into fibres, there are two broad areas that must be covered. These are synthesis of the feedstock (the unspun silk dope in spiders), and synthesis of the spinning conditions (the funnel, valve, tapering duct, and spigot). There have been a number of different approaches but few of these methods have produced silk that can efficiently be synthesised into fibres.
Later Todd enrolled Leaf Fielding as a tabletter, responsible for turning the raw material into accurately measured doses. In 1973, the producers had a bust-up with the distributors and production ceased for a time. Kemp and Solomon set about organising another distribution network and recommenced LSD production in west Wales. Todd recruited a chemist, Andy Munro, to synthesise LSD for his distribution network at a laboratory they set up in Hampton Wick, Greater London.
Robin Dunbar Robin Dunbar originally studied gelada baboons in the wild in Ethiopia, and has done much to synthesise modern primatological knowledge with Darwinian theory into a comprehensive overall picture. The components of primate social systems 'are essentially alliances of a political nature aimed at enabling the animals concerned to achieve more effective solutions to particular problems of survival and reproduction'.Dunbar. 1988. Primate Social Systems. Chapman Hall and Yale University Press, p. 14.
In plants cellulose is synthesized at the plasma membrane by rosette terminal complexes (RTCs). The RTCs are hexameric protein structures, approximately 25 nm in diameter, that contain the cellulose synthase enzymes that synthesise the individual cellulose chains. Each RTC floats in the cell's plasma membrane and "spins" a microfibril into the cell wall. RTCs contain at least three different cellulose synthases, encoded by CesA (Ces is short for "cellulose synthase") genes, in an unknown stoichiometry.
The Nature of Existence also seeks to synthesise McTaggart's denial of the existence of time, matter etc. with their apparent existence. Despite the mystical tone of its conclusions, the philosophical method of The Nature of Existence is far from mystical. McTaggart arrived at his conclusions by a careful analysis of the essential requirements of any successful metaphysical system (Volume I) followed by a purported proof that only his system satisfies these requirements (Volume II).
The bark of willow trees contains salicylic acid, the active metabolite of aspirin, and has been used for millennia to relieve pain and reduce fever. Medicinal plants Medicinal plants, also called medicinal herbs, have been discovered and used in traditional medicine practices since prehistoric times. Plants synthesise hundreds of chemical compounds for functions including defence against insects, fungi, diseases, and herbivorous mammals. Numerous phytochemicals with potential or established biological activity have been identified.
Ernest Arthur Gardner significantly contributed to the study of medieval architecture and sculpture. Gardner's publications, particularly his broad surveys of medieval sculpture, are most famous for their ability to effectively and succinctly synthesise existing material, research and findings of other academics on the topic. Gardner was also able to make medieval art more accessible to the wider public through offering sumptuous illustrations in his works, many of which became standardised academic textbooks.
Methods to synthesise BABA are known from at least 1857. Early methods to produce BABA included from ammonia and crotonic acid under pressure; from the acetoacetic ester phenylhydrazone; or from malonic acid, acetaldehyde, and ammonia. In 1957, Zilkha reported a new simpler method based on adding amines to crotonic acid and then catalytically hydrogenolysing the product to produce BABA. Since 2000, methods to produce only the S stereoisomer of BABA have also been reported.
This methodology was used to collect high quality mass spectra of diverse analytes. Besides the advantage of low internal energy of the ions, which preserves fragile species and intermediates, the methodology helps in miniaturising mass spectrometry. Ion-based chemistry is now used to synthesise structures such as metal grasslands, extending over cm2 areas. He discovered noble metal nanoparticle-based drinking water purification methods and developed the world’s first drinking water filters utilising nanochemistry.
The device has been used to recreate the pressure existing deep inside planets to synthesise materials and phases not observed under normal ambient conditions. Notable examples include the non-molecular ice X, polymeric nitrogen and metallic phases of xenon and potentially hydrogen. A DAC consists of two opposing diamonds with a sample compressed between the polished culets (tips). Pressure may be monitored using a reference material whose behavior under pressure is known.
An Economic Intelligence Collection Unit was established in Washington to synthesise Safehaven reports and improve the direction of Office of Strategic Services contribution. Operation Safehaven leaders also researched into the escape of Nazi leaders themselves and investigated how the movement of assets correlated with the movements of Nazis in South America. Research into ratlines and the involvement of airline KLM were conducted to assist in the tracking of Nazi’s and their assets.
While in other anhydrobionts, such as the brine shrimp, this desiccation tolerance is thought to be linked to the production of trehalose, a non-reducing disaccharide (sugar), bdelloids apparently cannot synthesise trehalose. In bdelloids, a major cause of the resistance to desiccation, as well as resistance to ionizing radiation, is a highly efficient mechanism for repairing the DNA double-strand breaks induced by these agents. This repair mechanism likely involves mitotic recombination between homologous DNA regions.
RuBisCO is thought to be the single most abundant protein on Earth. Phototrophs use the products of their photosynthesis as internal food sources and as raw material for the biosynthesis of more complex organic molecules, such as polysaccharides, nucleic acids and proteins. These are used for their own growth, and also as the basis of the food chains and webs that feed other organisms, including animals such as ourselves. Some important phototrophs, the coccolithophores synthesise hard calcium carbonate scales.
A spin and parity of 8− was assigned to the isomer. ;250No In 2003, scientists at the FLNR reported that they had been able to synthesise 249No, which decayed by SF with a half-life of 54 μs. Further work in 2006 by scientists at the ANL showed that the activity was actually due to a K-isomer in 250No. The ground state isomer was also detected with a very short half-life of 3.7 μs.
The membrane lipids of Thaumarchaeota are composed of glycerol dialkyl glycerol tetraethers (GDGTs) which contain 0-3 cyclopentane moieties. Thaumarchaeota also synthesise crenarchaeol which contains four cyclopentane moieties and a single cyclohexane moiety and a regio-isomer. The cyclohexane and cyclopentane rings, formed by internal cyclisation of one of the biphytane chains,Schouten, S., Hopmans, E. C., and Sinninghe Damsté, J. S., 2013, The organic geochemistry of glycerol dialkyl glycerol tetraether lipids: A review: Organic Geochemistry, v. 54, no.
Also that year he was elected the Dean of the Faculty of Science at Osaka University. In 1955 Shoda was appointed as President of Osaka University, a role in which he remained for six years. His achievements as President include foundations of two new faculties: the Faculty of Letters and the Faculty of Engineering Science, both based at Toyonaka, Osaka. The Faculty of Engineering Science was an ambitious attempt to synthesise two traditional disciplines: science and engineering.
The field was founded by Wilhelm Cauer after reading Ronald M. Foster's 1924 paper A reactance theorem. Foster's theorem provided a method of synthesising LC circuits with arbitrary number of elements by a partial fraction expansion of the impedance function. Cauer extended Foster's method to RC and RL circuits, found new synthesis methods, and methods that could synthesise a general RLC circuit. Other important advances before World War II are due to Otto Brune and Sidney Darlington.
They need to be political fixers, able to understand the politics and identify the key players. They need to be good storytellers, able to synthesise simple compelling stories from the results of the research. They need to be good networkers to work effectively with all the other stakeholders, and they need to be good engineers, building a programme that pulls all of this together. # Policy entrepreneurs need clear intent – they need to really want to do it.
The adenine-rich sequence in LINE transcript base pairs with the cut strand to flag where the LINE will be inserted with hydroxyl groups. Reverse transcriptase recognises these hydroxyl groups to synthesise LINE retrotransposon where the DNA is cut. Like with LTR retrotransposons, this new inserted LINE contains eukaryotic genome information so it can be copied and pasted into other genomic regions easily. The information sequences are longer and more variable than those in LTR retrotransposons.
He taught for thirty years at the University of Melbourne, from 1962 to 1992, influencing several generations of Victorian botanists and foresters. His professional expertise ranged from angiosperms, pteridophytes, bryophytes, lichens and fungi. He was also able to synthesise many biological problems ecologically, especially in Mountain Ash forests including geology, plant and animal species interactions, the effects of fire and climate, insect and seed dispersal. He wrote more than 200 scientific articles in over 20 publications.
Structurally, phenanthriplatin is similar to cisplatin, differing only in the presence of a phenanthridine ligand instead of a chloride in its structure. To synthesise phenanthriplatin, a one equivalent of silver nitrate is added to solution of cisplatin in dimethylformamide. The mixture is stirred at 55 °C away from light and the resulting silver chloride precipitate is filtered out. Next, phenanthridine is added to the supernatant and this is also mixed at 55 °C for 16 hours.
It can be used to synthesise (diphenyl)methyl esters and ethers with carboxylic acids and alcohols respectively. It can also generate the (diphenyl)methyl carbene and nitrogen gas upon illumination by ultraviolet light or heating. It can also be electrolysed to form the Ph2CN anion, which can decompose to form the Ph2C− anion radical. If carried out in dimethylformamide and tetrabutylammonium perchlorate, these can react to form benzophenone azine, which has the formula Ph2C=N-N=CPh2.
Leghemoglobin from soybean. Leghemoglobin (also leghaemoglobin or legoglobin) is an oxygen carrier and hemoprotein found in the nitrogen-fixing root nodules of leguminous plants. It is produced by these plants in response to the roots being colonized by nitrogen-fixing bacteria, termed rhizobia, as part of the symbiotic interaction between plant and bacterium: roots not colonized by Rhizobium do not synthesise leghemoglobin. Leghemoglobin has close chemical and structural similarities to hemoglobin, and, like hemoglobin, is red in colour.
It is a member of the FASII cycle along with FabI and FabA, which synthesise the precursors utilised by FabG. Another gene necessary for synthesis of di-rhamnolipids, rhlC, has also been identified. RhlC catalyses the addition of the second rhamnose moiety to mono-rhamnolipids forming di-rhamnolipids, hence is often labelled rhamnosyltransferase 2. Like rhlA and rhlB, rhlC is thought to be an ancestral gene controlled by the same quorum sensing system as rhlA and rhlB.
The CH2Cl2 is then evaporated using a vacuum, creating an oil which is then dissolved in a nonaqueous ether. Finally, HCl gas is bubbled through the mixture to produce 4-methylmethcathinone hydrochloride. This method produces a mixture of both enantiomers and requires similar knowledge to that required to synthesise amphetamines and MDMA. Mephedrone synthesis scheme from 4-methylpropiophenone It can also be produced by oxidising the ephedrine analogue 4-methylephedrine using potassium permanganate dissolved in sulfuric acid.
The Corey-Kim oxidation is an oxidation reaction used to synthesise aldehydes and ketones from primary and secondary alcohols. It is named for American chemist and Nobel Laureate Elias James Corey and Korean-American chemist Choung Un Kim. The Corey-Kim oxidation Although the Corey-Kim oxidation possesses the distinctive advantage over Swern oxidation of allowing an operation above –25 °C, it is not so commonly used due to issues with selectivity in substrates susceptible to chlorination by N-chlorosuccinimide.
The woman's urine flow is strong and hot, resulting in a central penile form; the man's is diffuse and cooler, and creates the labial circumference. In a poem entitled Piss Posy (1991) Chadwick describes the works as "Vaginal towers with male skirt/ Gender bending water sport?". Chadwick plays on sexual difference, reversing gender roles and provoking uncertainty of the singularity and specificity of gender. Piss Flowers "synthesise sexual difference through the erotic play both of their making and their forms".
As an attempt to synthesise the disparate material, it has not been superseded despite later discoveries at sites such as Nimrud, but only refined in its view of dating and distribution. In 1972, Maxwell-Hyslop gave a lecture at the Fifth International Congress of Iranian Art and Archaeology, discussing how beads or granules of gold could be attached to rings and bracelets, noting that the art evidently originated from Queen Pu-Abi's tomb, dating to 3500 years b.p. in Ur.
Microreactors can be used to synthesise material more effectively than current batch techniques allow. The benefits here are primarily enabled by the mass transfer, thermodynamics, and high surface area to volume ratio environment as well as engineering advantages in handling unstable intermediates. Microreactors are applied in combination with photochemistry, electrosynthesis, multicomponent reactions and polymerization (for example that of butyl acrylate). It can involve liquid-liquid systems but also solid-liquid systems with for example the channel walls coated with a heterogeneous catalyst.
The first attempt to synthesise livermorium was performed in 1977 by Ken Hulet and his team at the Lawrence Livermore National Laboratory (LLNL). They were unable to detect any atoms of livermorium. Yuri Oganessian and his team at the Flerov Laboratory of Nuclear Reactions (FLNR) subsequently attempted the reaction in 1978 and met failure. In 1985, a joint experiment between Berkeley and Peter Armbruster's team at GSI, the result was again negative with a calculated cross-section limit of 10–100 pb.
The book used the multiple and separate details to synthesise encyclopaedic surveys that typified the approach of the natural historians and antiquaries, what Barbara Maria Stafford has described as "cross-referencing material bits of distant reality". An 1803 article on the Rosetta Stone was amongst the earliest published research.1803: "Has tabulas inscriptionem ... ad formam et modulum exemplaris inter spolia ex bello Aegyptiaco nuper reportati et in Museo Britannico asservati suo sumptu incidendas curavit Soc. Antiquar. Londin. A.D. MDCCCIII" in Vetusta Monumenta vol.
His most systematic work, A Letter on the Three Stages of the Monastic Life, is misattributed to Philoxenus of Mabbug in the manuscripts. Like Philoxenus, Joseph taught that the monastic life fosters the charismatic gifts. He belonged to the same theological family as Isaac of Nineveh, Simon of Taibuteh and John of Dalyatha. He was the first to synthesise the three contemplations of the Hellenistic scholar Evagrius Ponticus (4th-century) with the tripartite division of the Syriac John of Apamea (5th century).
Any two-pole circuit is guaranteed to meet the port condition by virtue of Kirchhoff's current law and they are therefore one-ports unconditionally. All of the basic electrical elements (inductance, resistance, capacitance, voltage source, current source) are one-ports, as is a general impedance. Study of one-ports is an important part of the foundation of network synthesis, most especially in filter design. Two-element one-ports (that is RC, RL and LC circuits) are easier to synthesise than the general case.
The other diet included cholesterol. The observations of the experiment indicated that Schoenheimer and his associates’ theories that plant sterols were not absorbable were probable. Furthur studies were conducted and the findings concluded that plant sterols were non-absorbable, and therefore animals with plant only diets must synthesise the cholesterol necessary for their tissues as they do not receive absorbable cholesterol. During this period Schoenheimer became aware that cholesterol had an intermediary metabolism and that it was chemically inconvertable with other sterols.
He was said to be "unrivalled in his ability to distil and synthesise complex policy developments and present them in a clear and digestible manner for non- specialists" in 1999. He is frequently called upon to chair large conferences on health policy in England. He was said by the Health Service Journal to be the 38th most powerful person in the English NHS in December 2013. In the June 2018 Birthday Honours he was appointed a CBE for his services.
Virtual Studio Technologies or VSTs are devices used to replicate analog effects, instruments and effects that used to be commonly found in studios, for audio processing and synthesis within DAW software. VST instruments and VST effects are most commonly used; however, other types of VSTs also exist, such as various spectrum analysers. Some VSTs also emulate traditional synthesisers and samplers. VST instruments synthesise sound by taking a MIDI input and then sending it to an output or through VST effects via effects chaining.
Therefore, mice carrying a non-functional Mx allele fail to synthesise the Mx protein and are more susceptible to influenza infection. Alternatively, immunocompromised individuals due to existing illnesses may have a defective immune system which makes them more vulnerable to damage by the virus. Furthermore, a number of viruses display variable pathogenicity depending on the age of the host. Mumps, polio, and Epstein-Barr virus cause more severe disease in adults, while others like rotavirus cause more severe infection in infants.
The primary function of EC cells is to synthesise and secrete serotonin for modulation of gastrointestinal neurons. Serotonin, also named 5-hydroxytryptamine (5HT), can be classified as a hormone, neurotransmitter and a mitogen. It is primarily known for its role in the central nervous system but plays an important role in the periphery, with the largest endogenous pool of serotonin residing in the gut (90% of endogenous store). In the ENS, serotonin is an essential modulator of sensory transduction and mucus secretion.
Cysts average 0.447 mm in diameter, and have been found at concentrations of 250 per 100 cm2. They are laid on gravel in the middle of ditches or ponds, to avoid (it is speculated) large animals such as sheep transporting the cysts onto land. The cysts can survive drought and sub-zero temperatures, and can even synthesise haemoglobin if there is a lack of oxygen. As the pond dries out in the summer, the cysts will lie dormant until immersed in water.
Lithium intercalation into solid hosts is the fundamental mechanism underpinning the operation of electrodes in rechargeable lithium batteries. He seeks to synthesise new lithium intercalation compounds with unusual properties or combinations of properties. He is especially interested in cathode materials for Li and Na ion batteries. Recently his work in this area has been concerned with compounds which can store additional charge, beyond the transition metal redox capacity, by participation of oxygen in reversible anionic redox processes, including the formation of molecular oxygen in the solid.
The DAINV reaction was used to synthesise the PDE-I and PDE-II sections of (-)-CC-1065. The first reaction in the sequence is a DAINV reaction between the tetrazine and vinyl acetal, followed by a retro-Diels–Alder reaction to afford a 1,2-diazine product. After several more steps, an intramolecular DAINV reaction occurs, followed again by a retro Diels-Alder in situ, to afford an indoline product. This indoline is a converted into either PDE-I or PDE-II in a few synthetic steps.
Biomedical researchers have examined the applications of rhodium compounds and their derivatives in medicine and reported one potential application for a rhodocene derivative as a radiopharmaceutical to treat small cancers. Rhodocene derivatives are used to synthesise linked metallocenes so that metal–metal interactions can be studied; potential applications of these derivatives include molecular electronics and research into the mechanisms of catalysis. The value of rhodocenes tends to be in the insights they provide into the bonding and dynamics of novel chemical systems, rather than their applications.
P.aeruginosa strains which are unable to synthesise pyocyanin can still benefit from its effects if the strain has co-infected the lung with wild-type strains which can produce pyocyanin. Biosynthesis can be impaired by disrupting the aro pathway which is responsible for the synthesis of chorismic acid from shikimate. Chorismic acid is the precursor of pyocyanin. :shikimic acid → chorismic acid → phenazine-1-carboxylic acid → 5-methylphenazine-1-carboxylic acid betaine → pyocyanin The complete virulence of P. aeruginosa can only be experienced when pyocyanin is produced.
Generalized contraction (A) and expansion (B). Ring expansion and ring contraction reactions in the course of organic synthesis refer to a set of reactions which can lead to the expansion or contraction of an existing ring. This often makes it possible to access structures that would be difficult if not impossible to synthesise with single cyclization reactions. Ring expansions are valuable because they allow access to larger systems that are difficult to synthesize through a single cyclization due to the slow rate of formation.
As well as being attracted to the flower's fragrance, Vanilla may be attracting pollinators by mimicking other nectar-producing flowers. V. polylepis flowers so infrequently that natural pollination events have never been observed. However, its morphological similarity to Vanilla planifolia may suggest that it too is pollinated by a bee, albeit from a different group of bees, as euglossine bees are restricted to the Americas. Many orchids form symbiotic relationships with soil fungi in order to obtain the nutrients that they cannot synthesise themselves (mycoheterotrophy).
The discovery of the 118 chemical elements known to exist as of 2020 is presented in chronological order. The elements are listed generally in the order in which each was first defined as the pure element, as the exact date of discovery of most elements cannot be accurately determined. There are plans to synthesise more elements, and it is not known how many elements are possible. Each element's name, atomic number, year of first report, name of the discoverer, and notes related to the discovery are listed.
Bluebells synthesise a wide range of chemicals with potential medicinal properties: they contain at least 15 biologically active compounds that may provide them with protection against insects and animals. Certain extracts – water-soluble alkaloids – are similar to compounds tested for use in combating HIV and cancer. The bulbs of bluebells are used in folk medicine as a remedy for leucorrhoea, and as a diuretic or styptic, while the sap can be used as an adhesive. The bluebell may be regarded as the United Kingdom's "favourite flower".
The reaction used to synthesise aromatic acid from a phenol in the presence of CO2 is known as the Kolbe-Schmitt reaction. (Review) Kolbe–Schmitt reaction mechanism By 1897 the German chemist Felix Hoffmann and the Bayer company prompted a new age of pharmacology by converting salicylic acid into acetylsalicylic acid—named aspirin by Heinrich Dreser. Other NSAIDs like ibuprofen were developed from the 1950s forward. In 2001, NSAIDs accounted for 70,000,000 prescriptions and 30billion over-the-counter doses sold annually in the United States.
In this condition not only the amount of lipids changes, but also the composition. It was observed that triacylglycerols largely increase in nitrogen depletion while other lipids, mainly polar glycerolipids, free fatty acids and diacylglycerols, slightly decrease. The increase in triacylglycerols in nitrogen depletion is much larger than the decrease in the other glycerolipids, supporting the hypothesis that the cells actively synthesise new triacylglycerols rather than just transforming the existing lipids into triacylglycerols. While triacylglycerols accumulate and lipid droplets enlarge, other important morphological changes take place.
"Stories, by definition, are fairly linear, so the two goals conflicted with each other", design director Christopher Stockman opined. During development, the team turned to earlier open world games to establish principles for innovation, adopting the design philosophy "everything matters". The team wanted to synthesise game mechanics together to make the missions, activities and customization options work in tandem. Stockman felt that previous open world games did not reward players for experimenting with the sandbox enough because story progression was siphoned off from free roam gameplay.
In 1765 Horace Walpole published The Castle of Otranto, widely regarded by modern literary historians to be the first occasion of Gothic fiction. A decade later, Clara Reeve wrote The Old English Baron, the first "Gothic" novel to be penned by a woman, and in 1783 Sophia Lee produced The Recess, a story set in the time of Queen Elizabeth I. These works prefigured much of the material and themes that Radcliffe would synthesise in her novels, most particularly ideas of the supernatural, terror, romance, and history.
This position is detailed in The Principles of Archaeology (2001). #Klejn's interest in ethnogenesis forced him to deal with the problem of how to synthesise different kinds of sources and with the place of archaeological sources in this synthesis. In Klejn's opinion ethnos is a category of in social psychology. This implies that the notion of a common origin is the uniting idea of ethnos, and any real attributes (the community of language, race, religion, culture and so on) are attached in various combinations to this notion.
To discourage seed predators, pulses contain trypsin inhibitors that interfere with digestion. Animals and plants have evolved to synthesise a vast array of poisonous products including secondary metabolites, peptides and proteins that can act as inhibitors. Natural toxins are usually small organic molecules and are so diverse that there are probably natural inhibitors for most metabolic processes. The metabolic processes targeted by natural poisons encompass more than enzymes in metabolic pathways and can also include the inhibition of receptor, channel and structural protein functions in a cell.
M56, near Runcorn and the River Weaver and the Weaver Viaduct Sir William Henry Perkin FRS discovered the first synthetic dye mauveine in 1856, produced from aniline, having tried to synthesise quinine at his home on Cable Street in east London. Perkin's work, alone, led the way to the British chemical industry. 21% of the UK's chemical industry is in North West England, notably around Runcorn and Widnes. The chemical industry is 6.8% of UK manufacturing; around 85% of the UK chemical industry is in England.
The genus Lepidothamnus was once part of Dacrydium in the classification by Bentham and Hooker in 1880. However, current taxonomy separates it as a distinct genus with three species, one endemic to southern Chile and the other two in New Zealand. All three species have a distinctive cone morphology not shared with other podocarps with its erect ovule, as well as the absence of resin ducts in the leaves. These three species also synthesise cupressuflavone as their major biflavonoid – a feature not found in other podocarps.
The first transgenic livestock were produced in 1985 and the first animal to synthesise transgenic proteins in their milk were mice, engineered to produce human tissue plasminogen activator in 1987. The first genetically modified animal to be commercialised was the GloFish, a Zebra fish with a fluorescent gene added that allows it to glow in the dark under ultraviolet light. It was released to the US market in 2003. The first genetically modified animal to be approved for food use was AquAdvantage salmon in 2015.
Although the individual lesions are very small, attack by hundreds or thousands of spider mites can cause thousands of lesions, thus can significantly reduce the photosynthetic capability of plants. The mite's natural predator, Phytoseiulus persimilis, commonly used as a biological control method, is one of many predatory mites which prey mainly or exclusively on spider mites. Other than certain aphids, T. urticae is the only animal known to be able to synthesise carotenoids. As in aphids, the genes for carotene synthesis appear to have been acquired through horizontal gene transfer from a fungus.
More recently, anaerobic fungi, typified by Piromyces equi, have been suggested to also synthesise a cellulosome complex, although the dockerin sequences of the bacterial and fungal enzymes are completely different. For example, the fungal enzymes contain one, two or three copies of the dockerin sequence in tandem within the catalytic polypeptide. In contrast, all the C. thermocellum cellulosome catalytic components contain a single dockerin domain. The anaerobic bacterial dockerins are homologous to EF hands (calcium-binding motifs) and require calcium for activity whereas the fungal dockerin does not require calcium.
The LEAP logo. Since 2009, the EPTA has made some progress thanks to a project European Research Council funded project known as the Large European Array for Pulsars (LEAP). The aim of this project is to coherently combine the five EPTA telescopes to synthesise the equivalent of a fully steerable 194-m dish.The Large European Array for Pulsars This will improve the accuracy with which the pulsar TOAs can be measured by an order of magnitude, essential for the first detection of gravitational waves within the next decade.
Realising the growth is due to the living metal that Kettlewell used in constructing K1, the Doctor races back to Kettlewell's lab to synthesise a batch of metal-biodegradable virus, a side discovery made by Kettlewell. The Doctor throws a bucket of solution containing the virus onto K1, and the robot slowly shrinks down in size before it vanishes. As they regroup back at UNIT headquarters, Sarah is saddened by the loss of K1. The Doctor offers to cheer her up with a trip in the TARDIS, extending the invitation to Harry as well.
Ernst Späth (14 May 1886, in Moravský Beroun (), northern Moravia - 30 September 1946, in Zurich) was an Austrian chemist, specializing in natural products. He was the first to synthesise mescaline and was one of the first to synthesize cuscohygrine on a small scale with Hans Tuppy. He lost everything in World War II, and died with no money. His former student Percy Lavon Julian returned to Vienna, paid for his funeral, and commissioned a bust of Späth, which is still displayed in the foyer of the Faculty of Chemistry of the University of Vienna.
1999 Widespread occurrence of the oceanic ultraplankter Prasinococcus capsulatus (Prasinophyceae), the diagnostic "Golgi-Decapore complex" and the newly discovered polysaccharide "capsulan" Research is currently underway to find potential applications for capsulan and how to maximise its production. The capsule's function is not clearly defined but various explanations have been suggested. One is that it offers protection to newly divided cells which lack a thick cell wall, another is that it provides a template for daughter cells to synthesise their new cell wall. The capsule may also interfere with filter feeding, thus reducing predation.
Gate control theory. A major hypothesis in the theory of pain perception is the hypothesized pain gates predicted by Wall and Melzack's Gate Control Theory. The theory predicts that the activation of central pain inhibitory neurons by non-pain sensing neurons prevents the transmission of non-harmful stimuli to pain centers in the brain. A loss of inhibitory neurons, GAD65/67 expression (the enzymes that synthesise GABA; the predominant inhibitory transmitter in the adult brain), has been observed in some systems following peripheral neuropathy such as in rats, and mice.
This section deals with the synthesis of nuclei of dubnium by so-called "cold" fusion reactions. These are processes which create compound nuclei at low excitation energy (~10–20 MeV, hence "cold"), leading to a higher probability of survival from fission. The excited nucleus then decays to the ground state via the emission of one or two neutrons only. ;209Bi(50Ti,xn)259−xDb (x=1,2,3) The first attempts to synthesise dubnium using cold fusion reactions were performed in 1976 by the team at FLNR, Dubna using the above reaction.
Since amino acids are needed to make proteins, which are essential for growth and repair of body tissues, these cannot be used only to produce glucose. This could pose a problem for the brain, since it is normally fuelled solely by glucose, and most fatty acids do not cross the blood–brain barrier. However, the liver can use long-chain fatty acids to synthesise the three ketone bodies β-hydroxybutyrate, acetoacetate and acetone. These ketone bodies enter the brain and partially substitute for blood glucose as a source of energy.
Schematic diagram of the CLAW hypothesis (Charlson et al., 1987) The hypothesis describes a feedback loop that begins with an increase in the available energy from the sun acting to increase the growth rates of phytoplankton by either a physiological effect (due to elevated temperature) or enhanced photosynthesis (due to increased irradiance). Certain phytoplankton, such as coccolithophorids, synthesise dimethylsulfoniopropionate (DMSP), and their enhanced growth increases the production of this osmolyte. In turn, this leads to an increase in the concentration of its breakdown product, dimethyl sulfide (DMS), first in seawater, and then in the atmosphere.
Phased Array Feeds are an experimental type of focal plane array using phased array technology in which antenna elements are closely spaced so that they do not act independently, but instead act as sensors of the electromagnetic field across the focal plane of the telescope. The outputs of the receivers are then coherently combined in a beamformer with appropriate weights to synthesise several discrete beams. They are currently being developed for the Apertif Apertif upgrade to the Westerbork Synthesis Radio Telescope, and for the Australian Square Kilometre Array Pathfinder radio telescope.
1390–1418) and Flann Mac Aodhagáin (alive 1640). By 1600 it was refined to the point that certain Anglo-Irish families were given spurious Gaelic ancestors and origin legends, such was their immersion in Gaelic culture. The first Irish historian who questioned the reliability of such accounts was Dubhaltach Mac Fhirbhisigh (murdered 1671), whose massive Leabhar na nGenealach included disparate and variant recensions. Unlike Geoffrey Keating Foras Feasa ar Éirinn, he did not attempt to synthesise the material into a unified whole, instead recording and transmitting it unaltered.
When glutamine eventually reaches the leaves, it is broken down and used to synthesise protein and non-amide amino acids such as aspartate, threonine, serine, glutamate, glycine, alanine and cystine. Together with sucrose and other solutes, these are then circulated in the phloem. The phloem sap of B. prionotes is unusual in having an extremely low ratio of potassium to sodium cations, and very low concentrations of phosphate and amino acids compared to chloride and sulfate anions. The low levels of potassium and phosphate reflect the extremely low availability of these minerals in the soil.
TIGAR can promote development or inhibition of several cancers depending on the cellular context. TIGAR can have some effect on three characteristics of cancer; the ability to evade apoptosis, uncontrolled cell division, and altered metabolism. Many cancer cells have altered metabolism where the rate of glycolysis and anaerobic respiration are very high whilst oxidative respiration is low, which is called the Warburg Effect (or aerobic glycolysis). This allows cancer cells to survive under low oxygen conditions, and use molecules from respiratory pathways to synthesise amino acids and nucleic acids to maintain rapid growth.
PARP activity has also been linked to the neurodegenerative properties of toxin induced Parkinsonism. 1-Methyl-4-phenyl-1,2,3,6-tetrahydropyridine (MPTP) is a neurotoxin that has been linked to neurodegeneration and development of Parkinson Disease-like symptoms in patients since 1983. The MPTP toxin’s effects were discovered when four people were intravenously injecting the toxin that they produced inadvertently when trying to street- synthesise the merpyridine (MPPP) drug. The link between MPTP and PARP was found later when research showed that the MPTP effects on neurons were reduced in mutated cells lacking the PARP gene.
In response, Motion, along with her academic advisor, Matthew H. Todd, and the Open Source Malaria team led a small team of high school students from Sydney Grammar School to synthesise the drug. The team produced 3.7 grams of pyrimethamine for under US$20, which would be worth between $US35,000 and $US110,000 in the United States according to Turing's pricing. This received significant media attention and was featured in The Guardian and Time magazine, and on ABC News (Australia), the BBC, and CNN. Motion, like her former research advisor, is a proponent of open science.
In response to the price hike of HIV/AIDS drug, pyrimethamine (Daraprim), by Turing Pharmaceuticals, Todd and the Open Source Malaria team led a small team of high school students from Sydney Grammar School to synthesise the drug. The students produced 3.7 grams of pyrimethamine for US$20, which would be worth between US$35,000 and US$110,000 in the United States based on hiked prices. This received significant media attention and was featured on ABC, BBC, CNN, The Guardian, and Time. Todd has been a vocal proponent of open science and open research.
These enzymes degrade complex biopolymers such as starch, cellulose and lignin into simpler substances which can be absorbed by the hyphae. In this way, molds play a major role in causing decomposition of organic material, enabling the recycling of nutrients throughout ecosystems. Many molds also synthesise mycotoxins and siderophores which, together with lytic enzymes, inhibit the growth of competing microorganisms. Molds can also grow on stored food for animals and humans, making the food unpalatable or toxic and are thus a major source of food losses and illness.
Furthermore, water is transferred from the hindgut, where osmotic pressure has already been reduced, to the stomach to dilute stomach content. Eventually, aphids consume xylem sap to dilute the stomach osmotic pressure. All these processes function synergetically, and enable aphids to feed on high-sucrose-concentration plant sap, as well as to adapt to varying sucrose concentrations. Plant sap is an unbalanced diet for aphids, as it lacks essential amino acids, which aphids, like all animals, cannot synthesise, and possesses a high osmotic pressure due to its high sucrose concentration.
In the 1980s, he participated in the exhibition on Italian abstract art in the framework of the 33rd Biennale di Venezia; he staged a personal exhibition in Bolzano in 1980 and another in Pordenone (Italy) in 1984; and he was the coauthor, with Giancarlo Pauletto, of a book on the Italian artist Genesio De Gottardo published in 1989.Luigi Veronesi and Giancarlo Pauletto. Genesio De Gottardo. Pordenone, Edizioni d'Arte, 1989 Luigi Veronesi was a polyvalent and eclectic artist who managed to synthesise the avant-garde movements of various regions of Europe.
Haeckel showed a main trunk leading to mankind with minor branches to various animals, unlike Darwin's branching evolutionary tree. Evolutionary ideas, although not natural selection, were accepted by German biologists accustomed to ideas of homology in morphology from Goethe's Metamorphosis of Plants and from their long tradition of comparative anatomy. Bronn's alterations in his German translation added to the misgivings of conservatives, but enthused political radicals. Ernst Haeckel was particularly ardent, aiming to synthesise Darwin's ideas with those of Lamarck and Goethe while still reflecting the spirit of Naturphilosophie.
" He enrolled on a nuclear physics course "to synthesise and test all knowledge for what was observable, workable and could truly help solve man's problems.""L. Ron Hubbard – Shaping the 21st century with solutions for a better world – Exploring the riddles of existence ". Church of Scientology International, 2005. Accessed March 8, 2011 Another profile calls him "a product of the atomic age" and describes how his classmates dreamed of unlocking the energy of the atom, while Hubbard himself sought to "discover the basic equations of life force, simply, to him, another kind of energy.
Compared to directing and facilitating contexts, there is a greater balance between the ratio of leader to follower creative contributions and supportive contributions in the integrating context. Each individual can receive credit for their distinct contribution, and successful leadership in this context depends on the leader's ability to synthesise others' creative inputs. Film directors are an example of leaders working in an integrating context, providing guidance to create a feature film that includes creative contributions from numerous people: screenwriters, actors, special effects technicians, costume designers, etc.Simonton, D. K. (2002).
Suckling had worked on such compounds extensively during World War II, when they were used in the production of high-octane aviation fuel, and in the purification of uranium-235. He proceeded to synthesise a variety of fluorinated hydrocarbons before evaluating them for anaesthetic properties. He liaised closely with clinicians, initially in setting target physicochemical properties for ideal agents and then later in evaluating the developed compounds. Suckling first investigated halothane's anaesthetic action by experimenting on mealworms and houseflies, and then forwarded it to Jaume Raventos, a pharmacologist, for evaluation of anaesthesia in other animals.
In 1911, Roland Scholl and Oscar Bally published an article on the synthesis of benzanthrone by condensation of anthraquinone with glycerol, a process that would later be called the Bally-Scholl synthesis. In 1932, Scholl was the first person to synthesise coronene. Over the course of his career, Scholl published about 180 scientific articles. He became a member of the Austrian Academy of Sciences in 1916, of the Saxon Academy of Sciences in 1920, and of the German Chemical Society as well as the Chemische Gesellschaft Karlsruhe in 1930.
The term "psychasthenia" is historically associated primarily with the work of Pierre Janet, who divided the neuroses into the psychasthenias and the hysterias, discarding the term "neurasthenia" since it implied a neurological theory where none existed.Ellenberger (1970), p. 375; Janet (1903) Whereas the hysterias involved at their source a narrowing of the field of consciousness, the psychasthenias involved at root a disturbance in the fonction du reél ('function of reality'), a kind of weakness in the ability to attend to, adjust to, and synthesise one's changing experience (cf. executive functions in today's empiricist psychologies).
Unlike Maitland, however, Bloch also wished to synthesise scientific history with narrative history. According to Stirling, he managed to achieve "an imperfect and volatile imbalance" between them. Bloch did not believe that it was possible to understand or recreate the past by the mere act of compiling facts from sources; rather, he described a source as a witness, "and like most witnesses", he wrote, "it rarely speaks until one begins to question it". Likewise, he viewed historians as detectives who gathered evidence and testimony, as juges d'instruction (examining magistrates) "charged with a vast enquiry of the past".
However, these innovations proved to be somewhat temporary, and in the late 80s Blackburn began to synthesise his skills into the overarching project of the Landscape Vision series. These works consist of a number of small panels which are carefully arranged to create a larger whole. The connection between individual pictures is often quite oblique, encouraging the viewer to trace a through-line which is meandering and non-linear, complementing the metamorphic aesthetic contained within each individual drawing. Many of the most recent images are quite sombre in tone and evoke the bleakness of the moorland near Huddersfield.
As DNA printing and DNA assembly methods have allowed commercial gene synthesis to become progressively and exponentially cheaper over the past years, artificial gene synthesis represents a powerful and flexible engineering tool for creating and designing new DNA sequences and protein functions. Besides synthetic biology, various research areas like those involving heterologous gene expression, vaccine development, gene therapy and molecular engineering, would benefit greatly from having fast and cheap methods to synthesise DNA to code for proteins and peptides. The methods used for DNA printing and assembly have even enabled the use of DNA as an information storage medium.
Thiamine serves several indispensable roles in the brain that affect cognitive function either directly or indirectly. It is a functional component of neuronal and microglial cell membranes, and serves as a modulator of the acetylcholine neurotransmitter system. Thiamine indirectly drives cognitive processes as a necessary cofactor in the pathways needed to synthesise fatty acids, steroid hormones, nucleic acids and precursory molecules for various compounds involved in brain function. It has been shown that cats suffer irreversible brain damage when deprived of thiamine that hinders memory and learning even after thiamine has been reintroduced to the diet.
In the first case study conducted in a university research department, the objectives were to identify how effective information flow within the department was and what improvement would be required. The methodology was tailored to the study by removing the costing stage and establishing a workgroup to assist at various stages of the process, whilst all other stages remained as per the above (promote, identify, analyse and synthesise). Recommendations were made by the auditor towards greater synergy and systems analysis and it was found that staff immediately recognised the value of this output.Buchanan & Gibb, 2008, pp.151-155.
In 1893, Methamphetamine was first synthesised from ephedrine by Nagayoshi Nagai and in 1919, Akira Ogata was the first to synthesise methamphetamine in a crystallized form. Ogata blended the red phosporus and ephedrine, which is derived from an Asian herbal plant, to produce an amphetamine that could be dissolved in water. The procedure involved reduction of ephedrine using iodine and red phosphorus. Ogata's synthesis of methamphetamine replaced much more complicated earlier syntheses, and continues to be used as the basis for modern production and usage of the drug.. Particularly, is the method favored in illegal drug production.
Other biological machines are responsible for energy production, for example ATP synthase which harnesses energy from proton gradients across membranes to drive a turbine-like motion used to synthesise ATP, the energy currency of a cell. Still other machines are responsible for gene expression, including DNA polymerases for replicating DNA, RNA polymerases for producing mRNA, the spliceosome for removing introns, and the ribosome for synthesising proteins. These machines and their nanoscale dynamics are far more complex than any molecular machines that have yet been artificially constructed. These molecular motors are the essential agents of movement in living organisms.
On the stage, the role of the main character, Paula Spencer, was also split between the soprano Claron McFadden and the actress Jacqueline Blom, with all other characters being represented by pre-recorded video and projected texts. In 2003, Defoort worked again with McFadden and Dreamtime in ConVerSations/ConSerVations, a project to synthesise Renaissance and contemporary musics. His second opera, again with Cassiers, was The House of Sleeping Beauties based on the eponymous novella by Yasunari Kawabata. It received its world premiere at La Monnaie, in May 2009, as part of the kunstenFESTIVALdesArts, before touring the Netherlands, Belgium, Luxembourg and France.
In bringing the problem to the attention of the highest allied military and civil authorities overseas, he lifted the global profile and priority of malaria control measures. It was calculated that Allied requirements for atebrin would be per annum, of which would be manufactured in the United Kingdom and in the United States. American production in 1942 was estimated at 60 tons but efforts were soon under way to increase production. The possibility of producing atebrin in Australia was considered, but the drug was complicated to synthesise and required little shipping space, although steps were taken to produce mosquito repellent.
Some Jarawan Bantu languages are listed in the Benue–Congo Comparative wordlist (henceforth BCCW) (Williamson & Shimizu 1968; Williamson 1973) and a student questionnaire at the University of Ibadan in the early 1970s provided additional sketchy data on others." According to Blench (2006): "Maddieson & Williamson (1975) represents the first attempt to synthesise this data on the position of these languages. Since that period, publications have been limited. . . . Lukas and Gerhardt (1981) analyse some rather hastily collected data on Mbula, while Gerhardt (1982) published an analysis of some of this new data and memorably named the Jarawan Bantu "the Bantu who turned back".
Leduc believed that it is necessary to appreciate biological processes from a physical perspective and constructed models from physics and chemistry to try to explain development and growth; these would typically involve ingenious combinations of chemicals to produce systems which mimicked the appearance of living processes such as karyokinesis and "remarkable fungus-like forms". He "[repudiated] extra-physical forces in the phenomena of life". According to Keller, these models were largely unsuccessful, "not just because of the conspicuous artificiality of his osmotic growths". Leduc sought to synthesise life "by directing the physical forces which are its cause" (in his own words).
In 1948, William McCormick theorized that vitamin C deficiency played an important role in many diseases and began to use large doses in patients. In the 1950s, Fred R. Klenner also tried vitamin C megadosage as a therapy for a wide range of illnesses, including polio. Irwin Stone stated that organisms that do not synthesise their own vitamin C due to a loss-of-function mutation have a disease he called "hypoascorbemia". This term is not used by the medical community, and the idea of an organism-wide lack of a biosynthetic pathway as a disease was not endorsed by Stone's contemporaries.
His early work includes the classic texts Mental Acts and Reference and Generality, the latter defending an essentially modern conception of reference against medieval theories of supposition. His Catholic perspective was integral to his philosophy. He was perhaps the founder of analytical Thomism (though the current of thought running through his and Elizabeth Anscombe's work to the present day was only ostensibly so named forty years later by John Haldane), the aim of which is to synthesise Thomistic and analytic approaches. Geach was a student and an early follower of Ludwig Wittgenstein whilst at the University of Cambridge.
Among these historical writings, the Troubles religieux du XVIe dans la Flandre maritime (1560-1570), published in 1876, particularly merits being remembered. He was one of the first to be devoted to research on medieval music and his numerous publications focused on subjects such as the Gregorian chant, the neumatic and measured notation, medieval instruments, and the theory and polyphony he called harmony. What distinguished Coussemaker from Fétis is the wide culture of the latter that enabled him to synthesise huge quantities of information in order to elaborate on abstract theories. De Coussemaker's approach is nonetheless more accurate, more scientific and more hypothetical.
See Laban and Lawrence (1943). Warren Lamb went on to synthesise these and his own findings and develop a method – now known as MPA – for analysing core initiatives in decision-making. While developing the grounded theory that underpins MPA, Warren Lamb discovered distinctions to be made between gestures, postural movements and what he dubbed “posture-gesture mergers” or “PGMʼs” (waves of consistently integrated movement, involving the whole body). While isolated gestures and certain postures might have some social or cultural significance in a specific context, PGMʼs have the potential to transcend cultural and social specificity, revealing a person's underlying motivations in decision-making.
Ed Anderson attended Magdalen College, Oxford, and graduated from the University with bachelor of arts degree in Chemistry in 1997, having completed his research project on gold nanoparticles under the supervision of Harry Anderson. Between 1997 and 2001, he completed a doctorate at Gonville and Caius College in the University of Cambridge under the supervision of Andrew Holmes. His research focused on the applications and synthesis of medium-ring lactones and ethers. He took up a two-year post-doctoral research position assisting Erik J. Sorensen at The Scripps Research Institute and helped to synthesise furanosteriod viridin.
"History of Art", Iraq National Intelligence Service, 2017, Online:; "Art in Iraq" in: Arab Encyclopedia, Online: He was active from at least the 1840s when he and his contemporaries produced a number of wall murals for the interior walls of the Musiory Baghdad as well as for buildings in Basra and Sulaymaniyah. These works were often inspired by Iraqi folk heritage."The Golden Triangle in Modern Iraqi Painting", Almada, 2016, Online: (translated from Arabic) He painted miniatures in both watercolor and oil. These works synthesise text, ornamentation, and painting in ways that had not been done previously.
Deposed as President of the Federation, she is using the pseudonym Commissioner Sleer and is enacting a pacification programme using a drug named Pylene-50. The Scorpio crew gain the formula for an antidote to Pylene-50 but this cannot reverse the drug's effects. Avon finds a way to synthesise the antidote and the crew attempt to create an alliance between independent worlds to resist the Federation and get the resources and manpower to mass-produce the Pylene 50 antidote. One of the alliance members, Zukan, betrays the alliance to Servalan and detonates explosives on Xenon base, which is damaged and the Scorpio crew are forced to abandon it.
Scavenger receptor class B, type I (SR-BI) is an integral membrane protein found in numerous cell types/tissues, including the liver and adrenal. It is best known for its role in facilitating the uptake of cholesteryl esters from high-density lipoproteins in the liver. This process drives the movement of cholesterol from peripheral tissues towards the liver, where cholesterol can either be secreted via the bile duct or be used to synthesise steroid hormones. This movement of cholesterol is known as reverse cholesterol transport and is a protective mechanism against the development of atherosclerosis, which is the principal cause of heart disease and stroke.
Unbinilium has not yet been synthesized, despite multiple attempts from German and Russian teams. One 2011 attempt from the German team at the GSI Helmholtz Centre for Heavy Ion Research had a suggestive but not conclusive result suggesting the possible production of 299Ubn, but the data were incomplete and did not match theoretical expectations. Planned attempts from Russian, Japanese, and French teams are scheduled for 2017–2020. Experimental evidence from these attempts shows that the period 8 elements would likely be far more difficult to synthesise than the previous known elements, and that unbinilium may even be the last element that can be synthesized with current technology.
A sketch of an early furnace used by Verneuil to synthesise rubies using the Verneuil process. Since the study of alchemy began, there have been attempts to synthetically produce precious stones, and ruby, being one of the prized cardinal gems, has long been a prime candidate. In the 19th century, significant advances were achieved, with the first ruby formed by melting two smaller rubies together in 1817, and the first microscopic crystals created from alumina (aluminium oxide) in a laboratory in 1837. By 1877, chemist Edmond Frémy had devised an effective method for commercial ruby manufacture by using molten baths of alumina, yielding the first gemstone-quality synthetic stones.
Painting by Hermann Groeber: Der Aufsichtsrat der 1925 gegründeten I.G. Farben AG, Carl Bosch and Carl Duisberg (in front sitting), Edmund ter Meer (third person from right with newspaper) During World War I, the German army faced a great threat from an ammunition shortage. Indeed, the nitrates that were crucial for the production of gunpowder could not be imported any more because of the blockade by the British Navy. As a result, the German chemical firms (BASF and Bayer among others) were pushed to successfully synthesise nitrates. However, because of the war, shortage in manpower arose, and Duisberg advised Max Bauer on a new solution.
Viruses are obligate intracellular parasites, characterised by extremely limited biological function, to the point where, while they are evidently able to infect all other organisms from bacteria and archaea to animals, plants and fungi, it is unclear whether they can themselves be described as living. Viruses can be either RNA or DNA viruses consisting of a single or double strand of genetic material (RNA or DNA respectively), covered in a protein coat and sometimes a lipid envelope. They thus lack all the usual machinery of the cell such as enzymes, relying entirely on the host cell's ability to replicate DNA and synthesise proteins. Most viruses are bacteriophages, infecting bacteria.
Since the discovery of crown ethers and cryptands by Pederson, Cram and Lehn (for which they received the Nobel Prize in 1987), the significance of molecules containing the repeat units -CH2-CH2-O- as coordinating ligands for metal cations has been recognised. By combining salts and polyethers such as polyethylene oxide (-CH2-CH2-O-)n, it is possible to synthesise thousands of metal-polyether complexes, alternatively known as polymer electrolytes. Such materials are co-ordination compounds in the solid state and support ionic conductivity. For 30 years it was believed that ionic conductivity was confined to amorphous polymers above Tg and that crystalline polymers were insulators.
The first attempt to synthesise seaborgium in cold fusion reactions was performed in September 1974 by a Soviet team led by G. N. Flerov at the Joint Institute for Nuclear Research at Dubna. They reported producing a 0.48 s spontaneous fission (SF) activity, which they assigned to the isotope 259Sg. Based on later evidence it was suggested that the team most likely measured the decay of 260Sg and its daughter 256Rf. The TWG concluded that, at the time, the results were insufficiently convincing. The Dubna team revisited this problem in 1983–1984 and were able to detect a 5 ms SF activity assigned directly to 260Sg.
Diagram of new and regenerated production Bio-available nitrogen occurs in the ocean in several forms, including simple ionic forms such as nitrate (NO3−), nitrite (NO2−) and ammonium (NH4+), and more complex organic forms such as urea ((NH2)2CO). These forms are used by autotrophic phytoplankton to synthesise organic molecules such as amino acids (the building blocks of proteins). Grazing of phytoplankton by zooplankton and larger organisms transfers this organic nitrogen up the food chain and throughout the marine food-web. When nitrogenous organic molecules are ultimately metabolised by organisms, they are returned to the water column as ammonium (or more complex molecules that are then metabolised to ammonium).

Theoretical developments in the electrical domain that were particularly useful were the representation of an electrical network as an abstract topological diagram (the circuit diagram) using the lumped element model and the ability of network analysis to synthesise a network to meet a prescribed frequency function. This approach is especially useful in the design of mechanical filters—these use mechanical devices to implement an electrical function. However, the technique can be used to solve purely mechanical problems, and can also be extended into other, unrelated, energy domains. Nowadays, analysis by analogy is a standard design tool wherever more than one energy domain is involved.
East facade. The harmony of vaulting structures in pyramidal fashion is noticeable. Interior view from West Light shines from the apses. The architecture of the church has been criticised in several ways through several epochs. It was especially debated after the second competition for Saint Sava in 1926/27,Tanja Damnjanović 2005: „Fighting“ the St. Sava: Public Reaction to the Competition for the Largest Cathedral in Belgrade. Centropa, 5 (2), 125-135 when no first prize was awarded, and after Patriarch Varnava assigned Bogdan Nestorović (1901–1975) in 1930 as winner of a second prize as principal architect to synthesise his plan with Aleksandar Deroko (1894-1988).
An example of an organolithium compound is methyllithium ((CH3Li)x), which exists in tetrameric (x = 4, tetrahedral) and hexameric (x = 6, octahedral) forms. Organolithium compounds, especially n-butyllithium, are useful reagents in organic synthesis, as might be expected given lithium's diagonal relationship with magnesium, which plays an important role in the Grignard reaction. For example, alkyllithiums and aryllithiums may be used to synthesise aldehydes and ketones by reaction with metal carbonyls. The reaction with nickel tetracarbonyl, for example, proceeds through an unstable acyl nickel carbonyl complex which then undergoes electrophilic substitution to give the desired aldehyde (using H+ as the electrophile) or ketone (using an alkyl halide) product.
This enzyme class plays a critical role in the biosynthesis of unsaturated fatty acids in plants, and are very specific to their substrates. A common theme in recent research has been to identify uncommon desaturases in various plants and isolate their genetic code. In particular, this can then be inserted into model cells (such as Escherichia coli) and up-regulated through metabolic engineering to skew the composition of oils produced by the model cells. This becomes a particularly lucrative endeavour if it becomes possible to successfully synthesise so-called Omega-3 fatty acids or other nutraceutical products from basic saturated fatty acids, and extract them from their hosts.
Rice (1921), p. 71 Virakta Tontadarya, Gummalapura Siddhalinga, Swatantra Siddhalingeshwara (1560) and Ghanalingideva (1560) are some well-known vachana poets who tried to recreate the glory days of the early poets, though the socio-political expediency did not exist. Mystic literature had a resurgence towards the beginning of the 15th century, in an attempt to synthesise the Veerashaiva and advaitha (monistic) philosophies; this trend continued into the 19th century. Prominent among these mystics was Nijaguna Shivayogi, by tradition a petty chieftain near the Kollegal region (modern Mysore district) turned Shaiva saint, who composed devotional songs collectively known as Kaivalya sahitya (or Tattva Padagalu, literally "songs of the pathway to emancipation").
Interpretation of results is always easier if organisms are grown in chemically defined media and media could be very simple as would be expected for a saprophytic organism first isolated from ditch water. In this context it is worth noting that, although methionine is supplied in all culture media, the organisms can synthesise methionine and in their natural environment they probably use sulfide available at low concentration. Methionine is required for branching and, if added just before branching of a growing culture, hydrogen sulfide, cysteine and homocysteine can all be used. Methods based on vortex mixing and osmotic shock cause death of many spores.
The Daily Telegraph reported in April 2009 that it was manufactured in China, but it has since been made illegal there. In March 2009, Druglink magazine reported it only cost a "couple of hundred pounds" to synthesise a kilogram of mephedrone, the same month, The Daily Telegraph reported manufacturers were making "huge amounts of money" from selling it. In January 2010, Druglink magazine reported dealers in Britain spent £2,500 to ship one kilogram from China, but could sell it for £10 a gram, making a profit of £7,500. A later report, in March 2010, stated the wholesale price of mephedrone was £4000 per kilogram.
They are unable to fix carbon or nitrogen, but can perform the TCA cycle with glyoxylate bypass and are able to synthesise all amino acids except glycine, as well as some cofactors. They also have an unusual and unexpected requirement for reduced sulfur. P. ubique and members of the oceanic subgroup I possess gluconeogenesis, but not a typical glycolysis pathway, whereas other subgroups are capable of typical glycolysis. Unlike Acaryochloris marina, P. ubique is not photosynthetic — specifically, it does not use light to increase the bond energy of an electron pair — but it does possess proteorhodopsin (including retinol biosynthesis) for ATP production from light.
This makes any partition of the Inuit language somewhat problematic. This article will use labels that try to synthesise linguistic, sociolinguistic and political considerations in splitting up the Inuit dialect spectrum. This scheme is not the only one used or necessarily one used by Inuit themselves, but its labels do try to reflect the usages most seen in popular and technical literature. In addition to the territories listed below, some 7,000 Greenlandic speakers are reported to live in mainland Denmark, and according to the 2001 census roughly 200 self-reported Inuktitut native speakers regularly live in parts of Canada which are outside traditional Inuit lands.
Mount Pleasant Radio Telescope is the southernmost antenna used in Australia's VLBI network Beginning in the 1970s, improvements in the stability of radio telescope receivers permitted telescopes from all over the world (and even in Earth orbit) to be combined to perform very-long-baseline interferometry. Instead of physically connecting the antennas, data received at each antenna is paired with timing information, usually from a local atomic clock, and then stored for later analysis on magnetic tape or hard disk. At that later time, the data is correlated with data from other antennas similarly recorded, to produce the resulting image. Using this method it is possible to synthesise an antenna that is effectively the size of the Earth.
It was investigated by the antiquarian William Stukeley, who noted its Christian symbolism but who thought that it had likely originated in France and been brought to England by fifteenth-century soldiers. In another instance, a Romano-British beaker decorated with Biblical scenes was discovered in a child's grave within the Anglo-Saxon cemetery at Long Wittenham, Oxfordshire during excavations led by John Yonge Akerman in the 1850s. Akerman regarded it as being early medieval and of Gaulish origin. The first attempt to synthesise archaeological and historical material to understand Romano-British Christianity was an academic paper published in the English Historical Review; written by Francis J. Haverfield in 1896, it remained little known among scholars.
The experience proved to be a turning point in his career and brought to focus his ideal to synthesise the classical tendency in art with his interest in esoteric philosophy which was the defining attribute of his Idealist aesthetic form then onwards. Delville produced several remarkable paintings during his time in Rome that reflect a dramatic evolution in his art towards a more refined expression of this Idealist aesthetic. These included his outstanding Orphée aux enfers (1896), a key initiatory work, as well as his great masterpiece of the period, his L'Ecole de Platon (1898), which he exhibited at the 1898 Salon d'Art Idéalist to universal praise.see Cole, ibid pp. 99–113.
The process utilises identical molecules of a molecular cluster compound as the nucleation sites for nanoparticle growth, thus avoiding the need for a high temperature injection step. Particle growth is maintained by the periodic addition of precursors at moderate temperatures until the desired particle size is reached. The molecular seeding process is not limited to the production of cadmium-free quantum dots; for example, the process can be used to synthesise kilogram batches of high quality II-VI quantum dots in just a few hours. Another approach for the mass production of colloidal quantum dots can be seen in the transfer of the well-known hot-injection methodology for the synthesis to a technical continuous flow system.
Marcela Bilek (born 20 January 1968) is a Professor of Applied Physics and Surface Engineering at the University of Sydney, Australia."Professor Marcela Bilek at the University of Sydney" Her research interests focus on the use of plasma related methods to synthesise thin film materials and modify surfaces and interfaces. She was named Fellow of the American Physical Society in 2012 and Fellow of the Institute of Electrical and Electronics Engineers (IEEE) in 2015 for contributions to the science and application of plasma processes for materials modification and synthesis. Among her many awards are the Malcolm- McIntosh Prize for Physical Scientist of the Year in 2002 and the Pawsey Medal awarded by the Australian Academy of Science in 2004.
Lars Fischer, the Academic Director at The Woolf Institute, criticized Abramson's work for privileging claims made by historians largely sympathetic to traditional Ukrainian narratives while claiming to follow the trend of synthesizing of Jewish and Ukrainian historiographical approaches; Abramson, in a rebuttal, rejected this criticism. In a later article, Fischer noted that while he would "now be more prepared to acknowledge the extent to which Abramson has indeed succeeded in creating a historiographical synthesis," he "would add that it is precisely the desire to synthesise rather than radically deconstruct the existing paradigms that is in fact the problem" and still maintains Abramson's "approach fairly consistently privileges and perpetuates the paradigms that traditionally constitute the National Ukrainian approach".
In soil, microorganisms that reside in the rhizosphere (a zone that includes the root surface and the soil that adheres to the root after gentle shaking) carry out nitrogen fixation, converting nitrogen gas to nitrogenous compounds. This serves to provide an easily absorbable form of nitrogen for many plants, which cannot fix nitrogen themselves. Many other bacteria are found as symbionts in humans and other organisms. For example, the presence of over 1,000 bacterial species in the normal human gut flora of the intestines can contribute to gut immunity, synthesise vitamins, such as folic acid, vitamin K and biotin, convert sugars to lactic acid (see Lactobacillus), as well as fermenting complex undigestible carbohydrates.
While working on their second studio album, they released a collection of remixed SMD originals entitled Sample and Hold, which contains eleven tracks and was released in the UK on 28 July 2008. In January 2009, they announced on their Myspace page that a new album would be released in 2009. They released a new track, "Synthesise", on 12 February, through a music video (directed by Kate Moross and Alex Sushon) that "features live visual accompaniment" for the track. Two days later, a new song was broadcast on BBC Radio 1 named "10,000 Horses Can't Be Wrong", soon followed by the release on 6 March of the official music video on their YouTube channel.
Sodium nitrite is mildly toxic in concentrations above 100 mg/kg, but small amounts are often used to cure meat and as a preservative to avoid bacterial spoilage. It is also used to synthesise hydroxylamine and to diazotise primary aromatic amines as follows: :ArNH2 \+ HNO2 → [ArNN]Cl + 2 H2O Nitrite is also a common ligand that can coordinate in five ways. The most common are nitro (bonded from the nitrogen) and nitrito (bonded from an oxygen). Nitro-nitrito isomerism is common, where the nitrito form is usually less stable. Fuming nitric acid contaminated with yellow nitrogen dioxide Nitric acid (HNO3) is by far the most important and the most stable of the nitrogen oxoacids.
Firstly, improving the temporal resolution of proxies by applying suitable dating methods such as radiocarbon, uranium-series, luminescence, etc. Secondly and most importantly, is to refine the available proxy database so that ambiguous and often, conflicting interpretations can be re-assessed as new information emerges. In light of this, two key studies have emerged, Jacobs and Roberts who evaluate and synthesise the dates for the Still Bay and Howiesons Poort periods across southern Africa and Chase who addresses the issues about MIS 4 environments and the role of climate forcing during this period. A current synthesis of environmental proxy evidence associated with MIS 4 indicates that the Still Bay and Howiesons Poort occurred during relatively humid conditions.
Seaby’s obituary in The Times (30 July 1953: 8) paid tribute above all to his ability to synthesise art and nature: his "studies of wildlife", the writer noted, are significant for the way in which "naturalistic truth is combined with decorative disposition", and "nobody could fail to be impressed by the illustrations in such books as Skewbald: The New Forest Pony; British Ponies; and The White Buck". Cathy Sloan concludes in an article for Nature in Art that Seaby's work bridges ‘the gap between fine art and so called "wildlife art"’ (1995: 10). Pierre Gusman admired his woodcuts in the Japanese style, and compared him with John Dickson Batten, William Giles and Sydney Lee in that field.
Most alcoholic beverages come from fermentation of carbohydrate-rich plant products such as barley (beer), rice (sake) and grapes (wine). Native Americans have used various plants as ways of treating illness or disease for thousands of years. This knowledge Native Americans have on plants has been recorded by enthnobotanists and then in turn has been used by pharmaceutical companies as a way of drug discovery. Plants can synthesise useful coloured dyes and pigments such as the anthocyanins responsible for the red colour of red wine, yellow weld and blue woad used together to produce Lincoln green, indoxyl, source of the blue dye indigo traditionally used to dye denim and the artist's pigments gamboge and rose madder.
Maiden Tower in left The Hajinski residence reflected the status, position and colossal authority of its owner. The lightness and airiness of its shape, emphasised by the seven spires of different height, the brilliantly designed corner façade, with its colourful tower and rich architectural décor carried out in the best traditions, and mosaic works in the style of ancient Assyria create a fantastic impression and take you to a fairytale world. The irrepressible fancy of the owner, the refined taste of the architect and the high quality of the construction created an authentic masterpiece of pure Baku architecture which managed to absorb and organically synthesise the influences of very different cultures. The Hajinski residence became separated apartments during the Soviet period.
A 1972 monograph outlined Rajneesh's concept of sannyas. It was to be a worldwide movement, rooted in the affirmation of life, playful, joyful and based on science rather than belief and dogma. It would not rely on ideology and philosophy, but on practices, techniques and methods aiming to offer every individual the chance to discover and choose their own proper religious path; the intent was to lead people to an essential, universal religiousness. The movement would be open to people of all religions or of none, experimenting with the inner methods of all religions in their pure, original form, not seeking to synthesise them but to provide facilities whereby each might be revived, maintained and defended and their lost and hidden secrets rediscovered.
As part of the Synthetic Yeast 2.0 project, various research groups around the world have participated in a project to synthesise synthetic yeast genomes, and through this process, optimise the genome of the model organism Saccharomyces cerevisae. The Yeast 2.0 project applied various DNA assembly methods that have been discussed above, and in March 2014, Jef Boeke of the Langone Medical Centre at New York University, revealed that his team had synthesized chromosome III of S. cerevisae. The procedure involved replacing the genes in the original chromosome with synthetic versions and the finished synthetic chromosome was then integrated into a yeast cell. It required designing and creating 273,871 base pairs of DNA – fewer than the 316,667 pairs in the original chromosome.
Often used synonymously with health economics, medical economics, according to Culyer,A.J. Culyer (1989) "A Glossary of the more common terms encountered in health economics" in MS Hersh-Cochran and KP Cochran (Eds.) Compendium of English Language Course Syllabi and Textbooks in Health Economics, Copenhagen, WHO, 215–34 is the branch of economics concerned with the application of economic theory to phenomena and problems associated typically with the second and third health market outlined above: physician and institutional service providers. Typically, however, it pertains to cost–benefit analysis of pharmaceutical products and cost-effectiveness of various medical treatments. Medical economics often uses mathematical models to synthesise data from biostatistics and epidemiology for support of medical decision-making, both for individuals and for wider health policy.
By the 1940s cultural anthropologists such as Leslie White and Julian Steward sought to revive an evolutionary model on a more scientific basis, and succeeded in establishing an approach known as neoevolutionism. White rejected the opposition between "primitive" and "modern" societies but did argue that societies could be distinguished based on the amount of energy they harnessed, and that increased energy allowed for greater social differentiation (White's law). Steward on the other hand rejected the 19th-century notion of progress, and instead called attention to the Darwinian notion of "adaptation", arguing that all societies had to adapt to their environment in some way. The anthropologists Marshall Sahlins and Elman Service prepared an edited volume, Evolution and Culture, in which they attempted to synthesise White's and Steward's approaches.
In 1962 he published his first important academic paper, a study of Roman coins found at the bottom of the River Walbrook. Although not a specialist in any one particular aspect of Romano-British archaeology, he was able to synthesise a wide range of evidence to develop a picture of life in Londinium, the Roman settlement located in the City of London, publishing The Roman City of London in 1965. The project had been suggested to him two years previously by the publisher Ernest Benn, and represented the first detailed study of Roman London to be published for 35 years. To produce it, Merrifield catalogued all known Romano-British remains in the city; at the same time he developed ideas for where further remains might be located.
In 1853, at the age of 15, Perkin entered the Royal College of Chemistry in London (now part of Imperial College London), where he began his studies under August Wilhelm von Hofmann. At this time, chemistry was still primitive: although the major elements had been discovered and techniques to analyze the proportions of the elements in many compounds were in place, it was still a difficult proposition to determine the arrangement of the elements in compounds. Hofmann had published a hypothesis on how it might be possible to synthesise quinine, an expensive natural substance much in demand for the treatment of malaria. Having become one of Hofmann's assistants, Perkin embarked on a series of experiments to try to achieve this end.
Harradence also graduated with a MSc in 1937, writing a master's thesis titled "Attempts to synthesise the pyridine analogue of vitamin B1". In 1939, Cornforth and Harradence, independently of each other, each won one of two Science Research Scholarships (the 1851 Research Fellowship) from the Royal Commission for the Exhibition of 1851, tenable overseas for two years. At the University of Oxford, Harradence was a member of Somerville College while Cornforth was at St. Catherine's College and they worked with Sir Robert Robinson, with whom they would collaborate for 14 years. During his time at Oxford, Cornforth found working for and with Robinson stimulating, and the two would often deliberate to no end until one had a cogent case against the other's counterargument.
Independence anarchism attempts to synthesise certain aspects of national liberation movements with an opposition to hierarchical institutions grounded in libertarian socialism. Where a certain nation or people exists with its own distinct language, culture and self- identity, independence anarchists concur with supporters of nationalism that such a nation is entitled to self-determination. While statist nationalists advocate the resolution of national questions by the formation of new states, independence anarchists advocate self-government without the need for a state and are committed to the key anarchist societal principles of federalisation, mutual aid and anarchist economics. Some supporters of the movement defend its position as a tactical one, arguing that secessionism and self-organisation is a particularly effective strategy with which to challenge state power.
Historically, Romanian researchers and inventors have made notable contributions to several fields. In the history of flight, Traian Vuia built the first airplane to take off under its own power and Aurel Vlaicu built and flew some of the earliest successful aircraft, while Henri Coandă discovered the Coandă effect of fluidics. Victor Babeș discovered more than 50 types of bacteria; biologist Nicolae Paulescu discovered insulin, while Emil Palade received the Nobel Prize for his contributions to cell biology. Lazăr Edeleanu was the first chemist to synthesise amphetamine, and he also invented the procedure of separating valuable petroleum components with selective solvents. During the 1990s and 2000s, the development of research was hampered by several factors, including: corruption, low funding, and a considerable brain drain.
The aim of the Moro Movement of Isatabu, in the Solomon Islands, has been described as "Sai lima horohoro tuali" – "Putting lands together in living as before". A movement for social economic and political improvement using co- operatives economic enterprises in combination with a regard for custom and tradition to synthesise a new social order. As the Marau-Hauba Council on Guadalcanal, became destabilised in 1956, while a 'back to custom' movement was gaining strength, centred in the south east coastal areas and on the villages in the Suta area – on the northern side of the interior mountains. At Makaruka and Veuru Moli, Pelise Moro started to mobilise people around stories of original creation and a return to the use of name Isatabu instead of Guadalcanal.
Coulson approaches Talbot, who has been ignoring his efforts to contact him, to prepare for an international symposium in Taiwan, to discuss how to deal with the Inhumans. Keeping an eye on them, May and Lincoln intervene when Carl Creel unexpectedly appears, overpowering him, but Talbot reveals that Creel's Hydra brainwashing has been undone, and he is now Talbot's bodyguard. Simmons tests Creel's blood and discovers that mixing it with that of an inactive Inhuman prevents Terrigen from affecting the blood, meaning that Creel's blood could be used to synthesise a 'vaccine' to remove the alien gene from dormant Inhumans. This causes an argument between Lincoln, who supports the idea of the vaccine, and Daisy, who believes Terrigenesis is the birthright of all Inhumans, good or evil.
The intensely blue colour of plastocyanin and its unusual redox properties had frustrated all attempts to synthesise a small molecule mimic. It was not until 1977 that his group finally determined the structure of plastocyanin crystallised from the poplar tree (see diagram at right); this was the first protein crystal structure determined in the southern hemisphere. Together with subsequent work in collaboration with Ed Solomon, this work led to understanding of the unusual geometry of the copper metal site (see diagram at left) as well as the spectroscopic and electrochemical properties characteristic of blue copper proteins. Later in his career, Freeman developed an interest in the applications of EXAFS spectroscopy to metalloprotein structure, collaborating with both James Penner-Hahn and Keith Hodgson.
The concept originally stated by Gottlieb Haberlandt in 1902 that all plant cells are totipotent and can be grown in vitro ultimately enabled the use of genetic engineering experimentally to knock out a gene or genes responsible for a specific trait, or to add genes such as GFP that report when a gene of interest is being expressed. These technologies enable the biotechnological use of whole plants or plant cell cultures grown in bioreactors to synthesise pesticides, antibiotics or other pharmaceuticals, as well as the practical application of genetically modified crops designed for traits such as improved yield. Modern morphology recognises a continuum between the major morphological categories of root, stem (caulome), leaf (phyllome) and trichome. Furthermore, it emphasises structural dynamics.
Plants synthesise a number of unique polymers like the polysaccharide molecules cellulose, pectin and xyloglucan from which the land plant cell wall is constructed. Vascular land plants make lignin, a polymer used to strengthen the secondary cell walls of xylem tracheids and vessels to keep them from collapsing when a plant sucks water through them under water stress. Lignin is also used in other cell types like sclerenchyma fibres that provide structural support for a plant and is a major constituent of wood. Sporopollenin is a chemically resistant polymer found in the outer cell walls of spores and pollen of land plants responsible for the survival of early land plant spores and the pollen of seed plants in the fossil record.
Renzi has occasionally been compared to former British Prime Minister Tony Blair for his political views. Renzi himself has previously cited Blair as an inspiration for him, and claims to be a supporter of Blair's ideology of the Third Way, which attempts to synthesise liberal economics and left-wing social policies. In an interview with the Italian talk show, Che tempo che fa, Renzi stated that his meeting with Bill and Hillary Clinton was the most interesting part of his trip to the United States, because he considered them as models of the progressive left-wing. In 2016, Renzi endorsed Hillary Clinton's campaign to be elected President of the United States, in an interview where he also expressed admiration for the policies of Bill Clinton and Barack Obama.
This production of colour images is still used today in printing, digital cameras, televisions, and computers. The replica of Maxwell’s colour box, which he used to quantitatively analyse and synthesise light colours in order to underpin his observations on colour mixing and colour perception (thereby extending Newton's work on Optics), was produced in the Cavendish Laboratory, Cambridge University. Maxwell's celebrated equations as depicted on the James Clerk Maxwell Statue in Edinburgh Maxwell’s most celebrated contribution was in deriving the equations governing electromagnetics (Maxwell’s equations). In his 1865 paper, A Dynamical Theory of the Electromagnetic Field, (This article followed a December 8, 1864 presentation by Maxwell to the Royal Society.) Maxwell defined electromagnetics in terms of 20 equations, later summarised in his 1873 book Treatise on Electricity and Magnetism.
Flaviviruses have a (+) sense RNA genome and replicate in the cytoplasm of the host cells. The genome mimics the cellular mRNA molecule in all aspects except for the absence of the poly-adenylated (poly-A) tail. This feature allows the virus to exploit cellular apparatus to synthesise both structural and non-structural proteins, during replication. The cellular ribosome is crucial to the replication of the flavivirus, as it translates the RNA, in a similar fashion to cellular mRNA, resulting in the synthesis of a single polyprotein. In general, the genome encodes 3 structural proteins (Capsid, prM, and Envelope) and 7 non-structural proteins (NS1, NS2A, NS2B, NS3, NS4A, NS4B, NS5). The genomic RNA is modified at the 5′ end of positive- strand genomic RNA with a cap-1 structure (me7-GpppA-me2).
DCYTB protein has also been found in other tissues, such as lung epithelial cells and in the plasma membrane of mature red blood cells of scorbutic species (unable to make ascorbate) such as human and guinea pig but not in other species which have retained the ability to synthesise ascorbate like mice and rat. This has led to the notion that Dcytb may have an additional role in ascorbate metabolism in scorbutic species. DCYTB protein has also been found in breast tissue (epithelial and myoepithelial cells) and high DCYTB levels are associated with a favourable prognosis in patients with breast cancer. A single nucleotide polymorphism (SNP) within the DCYTB promoter (SNP rs884409) which reduced functional DCYTB promoter activity was also associated with reduced serum ferrtin levels in a patient cohort with C282Y haemochromatosis.
" The reviewer concludes that Polonsky succeeds in his task, but says that the books are most successful when they manage to synthesise experiences across regions and time periods, particularly in the mini-studies of Jewish Places, Jewish Literature and Women. Timothy Snyder, reviewing Volume Three of The Jews in Poland and Russia in The Wall Street Journal, praises the book but suggests that Polonsky could have made a stronger link between imperial Russia and modern German anti-Semitism. Snyder suggests that after the 1917 revolution, the White Russian commanders fled to the west, bringing with them a concept of the Bolshevik revolution as profoundly Jewish. Snyder argues that the "Judeo- Bolshevik" idea, "brought west by Russians and Baltic Germans after the Bolshevik victory in Russia's civil wars, became an integral part of Hitler's vision.
Some purpose-developed strains of poppy now produce opium that is up to 26% morphine by weight. A rough rule of thumb to determine the morphine content of pulverised dried poppy straw is to divide the percentage expected for the strain or crop via the latex method by eight or an empirically determined factor, which is often in the range of 5 to 15. The Norman strain of P. Somniferum, also developed in Tasmania, produces down to 0.04% morphine but with much higher amounts of thebaine and oripavine, which can be used to synthesise semi-synthetic opioids as well as other drugs like stimulants, emetics, opioid antagonists, anticholinergics, and smooth-muscle agents. In the 1950s and 1960s, Hungary supplied nearly 60% of Europe's total medication-purpose morphine production.
A schematic representation of the molecular mechanism involved for screening recombinant cells The lac Z fragment, whose synthesis can be induced by IPTG, is capable of intra-allelic complementation with a defective form of β-galactosidase enzyme encoded by host chromosome (mutation lacZDM15 in E. coli JM109, DH5α and XL1-Blue strains). In the presence of IPTG in growth medium, bacteria synthesise both fragments of the enzyme. Both the fragments can together hydrolyse X-gal (5-bromo-4-chloro-3-indolyl- beta-D-galactopyranoside) and form blue colonies when grown on media where it is supplemented. Insertion of foreign DNA into the MCS located within the lac Z gene causes insertional inactivation of this gene at the N-terminal fragment of beta-galactosidase and abolishes intra- allelic complementation.
Jacobs's book The Green Economy: Environment, Sustainable Development and the Politics of the Future, published by Pluto Press in 1991, was an attempt to synthesise the relatively new fields of ecological and neoclassical environmental economics. Rejecting both the ‘green’ argument that environmental protection requires zero growth and the neoclassical approach of pricing environmental goods, the book argued for an essentially social-democratic system of ‘sustainability planning’. In this the state would use a variety of policy instruments, including taxation and regulation, to constrain the economy within biophysically-informed and publicly-decided environmental limits. After joining the Centre for the Study of Environmental Change at Lancaster University in 1994, Jacobs published a series of papers on the philosophy of sustainable development and environmental economics and the politics of environmental policy.
Due to the absence of peptidoglycan, the bacterium is naturally resistant to all β-lactam antibiotics (such as penicillin), to which Rickettsia species are normally sensitive to. Its genome totally lacks the genes for lipophosphoglycan synthesis, but does contain some for those of peptidoglycan. Important genes essential for peptidoglycan systhesis such as alr, dapF and PBP1 are missing: alr encodes an enzyme L-alanine racemase, which converts L-alanine to D-alanine in the first step of peptidoglycan synthesis pathway; dapF encodes diaminopimelate epimerase, which convert LL-2,6-diaminoheptanedioate (L,L-DAP) to meso-diaminoheptanedioate (meso-DAP); and PBP1 encodes penicillin-binding protein-1 (PBP1), which converts periplasmic lipid II to peptidoglycan. Thus, the bacterium cannot synthesise a typical peptidoglycan cell wall, and instead makes a peptidoglycan-like structure on its surface.
After his postdoc positions, he joined the Scripps Research Institute in La Jolla, California in 1982 as an Assistant Professor and is currently Professor in the Department of Molecular Biology and the Skaggs Institute for Chemical Biology. His laboratory focuses on the recognition of microbial pathogens by the immune system and has determined over 85 crystal structures of mouse, human, shark, and catalytic antibodies, with a variety of antigens, including steroids, peptides, carbohydrates and viral proteins, such as HIV-1 and Hepatitis C virus envelope glycoproteins. His team was reported by the 6 February 2004 edition of Science magazine to have managed to synthesise the hemagglutinin protein responsible for the 1918 outbreak of Spanish flu. Since 2000, he has directed the Joint Center for Structural Genomics (JCSG) that has pioneered innovative new methods for high throughput structural studies, including x-ray and NMR.
As part of Operation Taxable on 5–6 June 1944, Window was dropped by Avro Lancasters of 617 Squadron to synthesise a phantom invasion force of ships in the Straits of Dover and keep the Germans unsure as to whether the brunt of the Allied assault would fall on Normandy or in the Pas de Calais area. R. V. Jones later declared: "In my opinion, Joan Curran made an even greater contribution to victory, in 1945, than Sam." In early 1944 the Currans were part of a group of British scientists invited to go to the US to take part in the Manhattan Project – the Allied project to develop an atomic bomb. They joined the British Mission at the Berkeley Radiation Laboratory in California, headed by Mark Oliphant, a distinguished Australian scientist that Joan knew from the Cavendish Laboratory.
Continuous-tone images are derived from conventional motion picture cameras, whilst images built up in the form of line structures are derived from telerecordings. To synthesise a moving picture these films are projected at the rate of 25 frames per second—the television picture frequency in Great Britain instead of 24 frames per second as in the motion picture industry. In America the television picture frequency is 30 frames per second and this raises considerable problems when conventional motion pictures which have been shot for the cinema at 24 frames per second are to be televised. Although films originally made for television in Great Britain (whether by telerecording or by conventional cinematography) will be photographed at 25 frames per second, films exposed for cinema exhibition at 24 frames per second are also transmitted for television at 25 frames per second.
In 2008, the team at RIKEN conducted the analogous reaction with a lead-206 target for the first time: : + → + They were able to identify 8 atoms of the new isotope 263Hs.Mendeleev Symposium. Morita In 2008, the team at the Lawrence Berkeley National Laboratory (LBNL) studied the analogous reaction with iron-56 projectiles for the first time: : + → + They were able to produce and identify 6 atoms of the new isotope 263Hs. A few months later, the RIKEN team also published their results on the same reaction. Further attempts to synthesise nuclei of hassium were performed the team at Dubna in 1983 using the cold fusion reaction between a bismuth-209 target and manganese-55 projectiles: : + → + x (x = 1 or 2) They were able to detect a spontaneous fission activity assigned to 255Rf, a product of the 263Hs decay chain.
Due to the rise of the Nazis in Germany, Eichengrün was unable to object when Hoffman first made the claim that he (Hoffman) invented aspirin, in the footnote of a 1934 German Encyclopedia. Hoffman's claim was once widely accepted, but many historians now consider it to be discredited. Eichengrün first claimed to have invented aspirin in a 1944 letter from Theresienstadt concentration camp, addressed to IG Farben (of which Bayer was a part), where he cited his many contributions to the company (which was highly influential in the concentration camps), including the invention of aspirin, as reasons for why he should be released. Five years later, Arthur Eichengrün published a paper in Pharmazie in 1949, where he explained that he had instructed Hoffmann to synthesise acetylsalicylic acid and that the latter had done so without knowing the purpose of the work.
Both in 19th-century research, which tended to see existing records of stories and folklore as imperfect fragments of partially lost myths, and in 20th-century structuralist work, which sought to identify underlying patterns and structures in often diverse versions of a given myth, there had been a tendency to synthesise sources to attempt to reconstruct what scholars supposed to be more perfect or underlying forms of myths. From the late 20th century, however, researchers influenced by postmodernism tended instead to argue that each account of a given myth has its own cultural significance and meaning, and argued that rather than representing degradation from a once more perfect form, myths are inherently plastic and variable.For example: McKinnell, John. 1994. Both One and Many: Essays on Change and Variety in Late Norse Heathenism, (Philologia: saggi, ricerche, edizioni 1, edited by T. Pàroli). Rome.
A reaction center is laid out in such a way that it captures the energy of a photon using pigment molecules and turns it into a usable form. Once the light energy has been absorbed directly by the pigment molecules, or passed to them by resonance transfer from a surrounding light-harvesting complex, they release two electrons into an electron transport chain. In green plants, the electron transport chain has many electron acceptors including phaeophytin, quinone, plastoquinone, cytochrome bf, and ferredoxin, which result finally in the reduced molecule NADPH and the storage of energy. The passage of the electron through the electron transport chain also results in the pumping of protons (hydrogen ions) from the chloroplast's stroma and into the lumen, resulting in a proton gradient across the thylakoid membrane that can be used to synthesise ATP using the ATP synthase molecule.
It is cognitively related to personal possession of multiple intelligences, notably those pertinent to visual and spatial data processing. The term suggests that in addition to any discursive processing of information that the commander may be conducting (such as mentally considering a specific plan), the commander is automatically establishing cognitive relationships between disparate pieces of information as they arrive, and is able to immediately re-synthesise their mental model of the battlefield. Even though there is no physical connection between the commander and his troops, other than conduits for discursive information such as radio signals, it is as if the commander had their own sensitive presence in each spot. One of the functions of a static map is to allow a traveler to decide upon a course of action suitable for getting from one point to another.
John Paul Jones contributed overdubbed wooden bass recorders in the opening section (he used a Mellotron and, later, a Yamaha CP70B Grand Piano and Yamaha GX1 to synthesise this arrangement in live performances) and a Hohner Electra-Piano electric piano in the middle section. The sections build with more guitar layers, each complementary to the intro, with the drums entering at 4:18. The extended Jimmy Page guitar solo in the song's final section was played for the recording on a 1959 Fender Telecaster given to him by Jeff Beck (an instrument he used extensively with the Yardbirds) plugged into a Supro amplifier,Steven Rosen, 1977 Jimmy Page Interview, Modern Guitars, 25 May 2007 (originally published in the July 1977, issue of Guitar Player magazine). although in an interview he gave to Guitar World magazine, Page also claimed, "It could have been a Marshall, but I can't remember".
In particular, since excreta are materials which other animals do not need, whatever energy value they might have, they are often unbalanced as a source of nutrients, and are not suitable as a source of nutrition on their own. However, there are many microorganisms which multiply in natural environments. These microorganisms do not simply absorb nutrients from these particles, but also shape their own bodies so that they can take the resources they lack from the area around them, and this allows them to make use of excreta as a source of nutrients. In practical terms, the most important constituents of detritus are complex carbohydrates, which are persistent (difficult to break down), and the microorganisms which multiply using these absorb carbon from the detritus, and materials such as nitrogen and phosphorus from the water in their environment to synthesise the components of their own cells.

The outcome of each vocational course is to provide participants with a range of knowledge, skills and competencies that will enable them to serve effectively in churches, parishes, para-church organisations, missionary organisations and schools.
A ribosome translating a protein The most complex macromolecular machines are found within cells, often in the form of multi-protein complexes. Some biological machines are motor proteins, such as myosin, which is responsible for muscle contraction, kinesin, which moves cargo inside cells away from the nucleus along microtubules, and dynein, which moves cargo inside cells towards the nucleus and produces the axonemal beating of motile cilia and flagella. "[I]n effect, the [motile cilium] is a nanomachine composed of perhaps over 600 proteins in molecular complexes, many of which also function independently as nanomachines ... Flexible linkers allow the mobile protein domains connected by them to recruit their binding partners and induce long-range allostery via protein domain dynamics." Other biological machines are responsible for energy production, for example ATP synthase which harnesses energy from proton gradients across membranes to drive a turbine-like motion used to synthesise ATP, the energy currency of a cell.

However, the lagging strand runs in the opposite direction and this presents quite a challenge since no known replicative polymerases can synthesise DNA in the 3' to 5' direction. The dimerisation of the replicative polymerases solves the problems related to efficient synchronisation of leading and lagging strand synthesis at the replication fork, but the tight spatial-structural coupling of the replicative polymerases, while solving the difficult issue of synchronisation, creates another challenge: dimerisation of the replicative polymerases at the replication fork means that nucleotide synthesis for both strands must take place at the same spatial location, despite the fact that the lagging strand must be synthesised backwards relative to the leading strand. Lagging strand synthesis takes place after the helicase has unwound a sufficient quantity of the lagging strand, and this "sufficient quantity of the lagging strand" is polymerised in discrete nucleotide chains called Okazaki fragments. Consider the following: the helicase continuously unwinds the parental duplex, but the lagging strand must be polymerised in the opposite direction.
Before the war, Germany had imported nitrates for propellant manufacture and only the discovery of the Haber process, to synthesise nitrates from atmospheric nitrogen, enabled Germany to continue the war; developing the Haber process and building factories to exploit it took time. Under Falkenhayn, the procurement of ammunition and the guns to fire it, had been based on the output of propellants, since the manufacture of ammunition without sufficient propellant fillings, was as wasteful of resources as it was pointless but Hindenburg and Ludendorff wanted firepower to replace manpower and ignored the principle. To meet existing demand and to feed new weapons, Hindenburg and Ludendorff wanted a big increase in propellant output to a month. In July 1916, the output target had been raised from which was expected to cover existing demand and the extra of output demanded by Hindenburg and Ludendorff could never match the doubling and trebling of artillery, machine- guns and trench mortars.
Pyramidal carbocation with composition The isolation of an ion with composition was first reported from investigations of hexamethyl Dewar benzene in the 1960s; a pyramidal structure was suggested based on NMR evidence and subsequently supported by disordered crystal structure data. In the early 1970s theoretical work led by Hepke Hogeveen predicted the existence of a pyramidal dication , and the suggestion was soon supported by experimental evidence. Spectroscopic investigation of the two-electron oxidation of benzene at very low temperatures (below 4 K) shows that a hexagonal dication forms and then rapidly rearranges into a pyramidal structure: 600px Three-dimensional representation of having a rearranged pentagonal-pyramid framework Direct, two-electron oxidation of hexamethylbenzene would be expected to result in a near-identical rearrangement to a pyramidal carbocation, but attempts to synthesise it in bulk by this method have been unsuccessful. However, a modification of the Hogeveen approach was reported in 2016, along with a high-quality crystal structure determination of .
Hot start PCR is a modified form of conventional polymerase chain reaction (PCR) that reduces the presence of undesired products and primer dimers due to non-specific DNA amplification at room (or colder) temperatures. Because the results of PCR are so useful, many variations and modifications of the procedure were developed in order to achieve a higher yields, hot start PCR is one of them. Hot start PCR follows the same principles as the conventional PCR - in that it uses DNA polymerase to synthesise DNA from a single stranded template, however, it utilises additional heating and separation methods, such as inactivating or inhibiting the binding of Taq polymerase and late addition of Taq polymerase, to increase product yield as well as provide a higher specificity and sensitivity. Non-specific binding is minimized by completing the reaction mix after denaturation Some ways to complete reaction mixes at high temperatures involve modifications that block DNA polymerase activity in low temperatures, use of modified deoxyribonucleotide triphosphates (dNTPs), and the physical addition of one of the essential reagents after denaturation.
232Th is a primordial nuclide, having existed in its current form for over ten billion years; it was forged in the cores of dying stars through the r-process and scattered across the galaxy by supernovae and neutron star mergers. The letter "r" stands for "rapid neutron capture", and occurs in core-collapse supernovae, where heavy seed nuclei such as 56Fe rapidly capture neutrons, running up against the neutron drip line, as neutrons are captured much faster than the resulting nuclides can beta decay back toward stability. Neutron capture is the only way for stars to synthesise elements beyond iron because of the increased Coulomb barriers that make interactions between charged particles difficult at high atomic numbers and the fact that fusion beyond 56Fe is endothermic. Because of the abrupt loss of stability past 209Bi, the r-process is the only process of stellar nucleosynthesis that can create thorium and uranium; all other processes are too slow and the intermediate nuclei alpha decay before they capture enough neutrons to reach these elements.
Unlike Wright's model however, this model has not been built physically, and is only a 3-D computer model. Internal gearing relationships of the Antikythera Mechanism, based on the Freeth and Jones proposal The system to synthesise the solar anomaly is very similar to that used in Wright's proposal: three gears, one fixed in the centre of the b1 gear and attached to the Sun spindle, the second fixed on one of the spokes (in their proposal the one on the bottom left) acting as an idle gear, and the final positioned next to that one; the final gear is fitted with an offset pin and, over said pin, an arm with a slot that in turn, is attached to the sun spindle, inducing anomaly as the mean Sun wheel turns.
