The results can be tabulated within two days. Automated sieving is an advanced way of sieving materials running through a process. Without having to extract the material, photoanalysis can take place, allowing for immediate results with pinpoint accuracy.
|
|
A large amount of materials can be readily loaded into sieve trays. Two common uses in the powder industry are wet-sieving of milled limestone and dry-sieving of milled coal. Disadvantages: many PSDs are concerned with particles too small for separation by sieving to be practical. A very fine sieve, such as 37 μm sieve, is exceedingly fragile, and it is very difficult to get material to pass through it.
|
|
Another disadvantage is that the amount of energy used to sieve the sample is arbitrarily determined. Over-energetic sieving causes attrition of the particles and thus changes the PSD, while insufficient energy fails to break down loose agglomerates. Although manual sieving procedures can be ineffective, automated sieving technologies using image fragmentation analysis software are available. These technologies can sieve material by capturing and analyzing a photo of material.

Screening during an excavation. The use of sieving is more common on research-based excavations where more time is available. Some success has been achieved with the use of cement mixers and bulk sieving. This method allows the quick removal of context by shovel and mattock yet allows for a high retrieval rate.
|
|
In addition to control of temperature (mentioned above), the main requirement is to obtain a consistent fineness of the product. From the earliest times, fineness was measured by sieving the cement. As cements have become finer, the use of sieves is less applicable, but the amount retained on a 45 μm sieve is still measured, usually by air-jet sieving or wet-sieving. The amount passing this sieve (typically 95% in modern general-purpose cements) is related to the overall strength-development potential of the cement, because the larger particles are essentially unreactive.

Sieves are also used to separate stones from sand. Sieving plays an important role in food industries where sieves (often vibrating) are used to prevent the contamination of the product by foreign bodies. The design of the industrial sieve is of primary importance here. Triage sieving refers to grouping people according to their severity of injury.

Fragmentation analysis is becoming a popular term in mining, agricultural and forestry industries. With the majority of money in these industries directed towards the proper sizing of materials, companies are using fragmentation analysis to determine various factors within an operation. The two main ways a company keeps track of fragmented material are through manual and automated sieving procedures. Manual sieving involves extracting a sample of material to analyze the size distribution.

Fresh polyacrylamide gels are further hydrophilic, electrically neutral and do not bind proteins. Sieving effects due to gravity-induced compression of the gel can be excluded for the same reasons. In a medium without molecular sieving properties a high-resolution can be expected. Before an electrophoretic run is started the prepared 4% T (total polymer content (T)), 2.67% C (cross-linker concentration (C)) gel is pre-run to equilibrate it.

Sieves in a variety of mesh sizes are used to separate fossils from sands and gravels. Sieving is a rougher technique for collecting fossils and can destroy fragile ones. Sometimes, water is run through a sieve to help remove silt and sand. This technique is called wet sieving Fossils tend to be very fragile and are generally not extracted entirely from the surrounding rock (the matrix) in the field.

In cryptography and number theory, TWIRL (The Weizmann Institute Relation Locator) is a hypothetical hardware device designed to speed up the sieving step of the general number field sieve integer factorization algorithm. During the sieving step, the algorithm searches for numbers with a certain mathematical relationship. In distributed factoring projects, this is the step that is parallelized to a large number of processors. TWIRL is still a hypothetical device — no implementation has been publicly reported.

As an undergraduate student at Valparaiso University, Sieving majored in history and physics. He then studied nuclear physics at Yale Graduate School in 1970-73 under D. Allan Bromley, and attended Yale Law School from 1973 - 1974. He received his medical degree from the University of Illinois College of Medicine in 1978 and a Ph.D. in bioengineering from the University of Illinois Graduate College in 1981. Sieving completed an ophthalmology residency at the University of Illinois Eye and Ear Infirmary in Chicago.

Many statements that can be made about POM apply equally to POC, and much of what is said in this article about POM could equally have been said of POC. Particulate organic matter is sometimes called macroorganic matter, or coarse fraction organic matter. Isolated by sieving or filtration, this fraction includes partially decomposed detritus and plant material, pollen, and other materials. When sieving to determine POM content, consistency is crucial because isolated size fractions will depend on the force of agitation.

In mathematics, the function field sieve was introduced in 1994 by Leonard Adleman as an efficient technique for extracting discrete logarithms over finite fields of small characteristic, and elaborated by Adleman and Huang in 1999. Sieving for points at which a polynomial-valued function is divisible by a given polynomial is not much more difficult than sieving over the integers – the underlying structure is fairly similar, and Gray code provides a convenient way to step through multiples of a given polynomial very efficiently.

The goal of TWINKLE is to implement the sieving step of the Number Field Sieve algorithm, which is the fastest known algorithm for factoring large integers. The sieving step, at least for 512-bit and larger integers, is the most time consuming step of NFS. It involves testing a large set of numbers for B-'smoothness', i.e., absence of a prime factor greater than a specified bound B. What is remarkable about TWINKLE is that it is not a purely digital device.

The resulting powder, referred to as "kief" or "drysift", is compressed with the aid of heat into blocks of hashish; if pure, the kief will become gooey and pliable. When a high level of pure THC is present, the end product will be almost transparent and will start to melt at the point of human contact. Ice-water separation is another mechanical method of isolating trichomes. Newer techniques have been developed such as heat and pressure separations, static-electricity sieving or acoustical dry sieving.

Sieving is a simple technique for separating particles of different sizes. A sieve such as used for sifting flour has very small holes. Coarse particles are separated or broken up by grinding against one another and the screen openings. Depending upon the types of particles to be separated, sieves with different types of holes are used.

Honey oil still contains waxes and essential oils and can be further purified by vacuum distillation to yield "red oil". The product of chemical separations is more commonly referred to as "honey oil." This oil is not really hashish, as the latter name covers trichomes that are extracted by sieving. This leaves most of the glands intact.

This keeps the timeline of the material remains consistent with one another. This is done usually though mechanical means where artifacts can be spot dated and processed through methods such as sieving or flotation. Afterwards, digital methods are then used record the excavation process and its results. Ideally, data from the excavation should suffice to reconstruct the site completely in three- dimensional space.

A noticeable other use is as growing medium in horticulture (usually after sieving). In the United Kingdom it is known as furnace bottom ash (FBA), to distinguish it from incinerator bottom ash (IBA), the non-combustible elements remaining after incineration. A pioneer use of bottom ash was in the production of concrete blocks used to construct many high-rise flats in London in the 1960s.

One-micron-thick Ti3C2 MXene membranes demonstrated ultrafast water flux (approximately 38 L/(Bar·h·m2) and differential sieving of salts depending on both the hydration radius and charge of the ions. Cations larger than the interlayer spacing of MXene do not permeate through Ti3C2 membranes. As for smaller cations, the ones with a larger charge permeate an order of magnitude slower than single-charged cations.

The pulverised ore is concentrated using visual sorting, sieving, gold panning, and by washing on riffle tables made of plastic sheets on heaps of sand. Final gold extraction is accomplished using mercury amalgamation. Mercury is typically burned off using an oxy-gas torch. The gold is sold to local agents, or may be exported directly to major markets for raw gold including India, China, Israel and Lebanon.

It is essentially non- sieving and optimal for electrophoresis of proteins greater than or equal to 200 ku (cf. agarose gel electrophoresis). Proteins migrate in it more or less on the basis of their free mobility. For these reasons interactions of the gel with the biomolecules are negligibly low, and thus, the proteins separate cleanly and predictably at a polymerization time of 69 hr (see figure Electropherogram).

Ogi (or Akamu) is a fermented cereal pudding from Nigeria, typically made from maize, sorghum, or millet. Traditionally, the grains are soaked in water for up to three days, before wet milling and sieving to remove husks. The filtered cereal is then allowed to ferment for up to three days until sour. It is then boiled into a pap, or cooked to make a creamy pudding.

Rock garnet is perhaps the garnet type used for the longest period of time. This type of garnet is produced in America, China and western India. These crystals are crushed in mills and then purified by wind blowing, magnetic separation, sieving and, if required, washing. Being freshly crushed, this garnet has the sharpest edges and therefore performs far better than other kinds of garnet.

It has a lower maintenance and is compact. It has a disadvantage of blocking of the mesh in case of batch sieving if the particles are fed immediately inside the machine barrel. Hence, the feeding rate shouldn't be very high. Another disadvantage of tumbler screening technique is that it would not be effective for higher particle sizes, which range from six inches to +20 mesh.

To produce marzipan, raw almonds are cleaned "by sieving, air elutriation, and other electronic or mechanical devices",Minifie: 1989, page 594. then immersed in water with a temperature just below the boiling point for about five minutes, in a process known as blanching. This loosens the almonds' skin, which is removed by passing the almonds through rubber-covered rotating cylinders. This process reduces hydrogen cyanide (HCN) concentration and increases water content.

Flotation can be undertaken manually with buckets, or by machine-assisted flotation where water is circulated through a series of tanks by a pump. Waterlogged plant remains are separated from the matrix by a combination of wet-sieving and/or small-scale flotation in a laboratory.Tolar et al. 2010. Recovery techniques for waterlogged archaeological sediments: a comparison of different treatment methods for samples from Neolithic lake shore settlements.

To provide a means of cleaning itself and to help mimic its natural habitat, a large bowl of sand should be available at all times. Dust bathing is a vital part of a hamster's daily routine and helps to keep their coat healthy and shiny by removing excess oils.Flint, 1966 ("Biotopes" p. 20–21). The sand can be kept clean by sieving or washing out with water and drying.

Palynomorphs are broadly defined as organic-walled microfossils between 5 and 500 micrometres in size. They are extracted from sedimentary rocks and sediment cores both physically, by ultrasonic treatment and wet sieving, and chemically, by chemical digestion to remove the non- organic fraction. Palynomorphs may be composed of organic material such as chitin, pseudochitin and sporopollenin. Palynomorphs that have a taxonomy description are sometimes referred to as palynotaxa.

Clays should be separated from the nonclay minerals to reduce interference of 00l peaks. Nonclay minerals can usually be separated by sieving samples at a small enough mesh. Samples should be lightly crushed but not pulverized because nonclay minerals will be reduced to clay sizes and become impossible to separate from the sample. Lightly crushing breaks apart the soft clays while keeping harder nonclays intact for easier removal.

Like all scallops the interior of each valve shows a central round scar which is the attachment area for the single strong adductor muscle which closes the two valves of the shell. The background color of the exterior of the shell in this species varies from yellow to light purple. Like almost all bivalve species, this one is a filter feeder, sieving microscopic algae from water that passes through its gills.

Squab forcemeat with cepes, anise, and combava juice Forcemeat (derived from the French farcir, "to stuff") is a uniform mixture of lean meat with fat made by grinding, sieving, or puréeing the ingredients. The result may either be smooth or coarse. Forcemeats are used in the production of numerous items found in charcuterie, including quenelles, sausages, pâtés, terrines, roulades, and galantines. Forcemeats are usually produced from raw meat, except in the case of a gratin.

The anterior teeth were angled anteriorly, while the posterior teeth were shorter and more upright. The upper and lower teeth interlocked; according to Bennett (2013) they formed a basket for sieving food items from water, though the lack of a pumping mechanism suggests a function more akin to spoonbill jaws, wading with the jaws open and closing them when catching individual prey, much as in other ctenochasmatoids.Wilton, Mark P.

Sok-mieum () is a mieum made with jujube, chestnut, and ginseng. Thinly sliced ginseng is simmered for an hour, and the water is used to make sok-mieum. Glutinous rice or glutinous foxtail millet, jujube, and chestnut is prepared in the same way: Boiling until mushy and double sieving. Glutinous rice-based sok-mieum is seasoned with sugar, while glutinous foxtail millet-based sok-mieum is seasoned with salt before being served.

After the Roman Empire, the use of burned lime and pozzolana was greatly reduced. Low kiln temperatures in the burning of lime, lack of pozzolana and poor mixing all contributed to a decline in the quality of concrete and mortar. From the 11th century, the increased use of stone in church and castle construction led to an increased demand for mortar. Quality began to improve in the 12th century through better grinding and sieving.

Over 40,000 objects were uncovered by excavating 36,000 layers and sieving eight tonnes of soil. When the extent and importance of the discoveries at Coppergate were realised, plans were made to allow permanent display of the remains of Jorvik within the excavation area. York Archaeological Trust created the Jorvik Viking Centre which opened to the public in April 1984. The exhibits in the Centre are based on evidence unearthed during the Coppergate excavations.

Operators are using fragmentation analysis to determine the effectiveness of various blasts. With automated sieving technology, workers can track the success of these blasts and receive instant results. Companies are using these results to determine what blasting method yielded the best results for their specific operation. The common variables associated with blast optimization are the provided Particle Size Distribution (PSD) from a shovel fragmentation system, geology including rock type and fracturing, and energy factor.

Non-glutinous rice flour is steamed in siru (steamer) and pounded in jeolgu (mortar) to form a dough. It is then cut into small pieces, rolled out flat and round, and filled with geopipat-so (white adzuki bean paste) and sealed. The filling can be made by husking adzuki beans (often the black variety), steaming and seasoning it with salt, and sieving it. Sesame oil is brushed on each tteok to prevent it from sticking.

Proteins are introduced into an Immobilized pH gradient gel composed of polyacrylamide, starch, or agarose where a pH gradient has been established. Gels with large pores are usually used in this process to eliminate any "sieving" effects, or artifacts in the pI caused by differing migration rates for proteins of differing sizes. Isoelectric focusing can resolve proteins that differ in pI value by as little as 0.01.Stryer, Lubert: "Biochemie", page 50.

The company has been dealing for decades with vacuum metallurgy (arc melting and vacuum induction melting) and powder metallurgy (milling technologies, sieving, powders classification and mixing, screen printing and sintering). In particular, by the available sintering technologies, processes under high vacuum or inert atmosphere and controlled conditions of temperature, time (traditional sintering) and pressure (hot uniaxial pressing and cold isostatic pressing) can be performed allowing to obtain either highly porous either full dense sintered bodies.

After Apollo and particularly during the development of the Constellation program, there was a large proliferation of lunar simulants produced by different organizations and researchers. Many of these were given three-letter acronyms to distinguish them (e.g., MLS-1, JSC-1), and numbers to designate subsequent versions. These simulants were broadly divided into highlands or mare soils, and were usually produced by crushing and sieving analogous terrestrial rocks (anorthosite for highlands, basalt for mare).

Mixtures of substances that are not soluble are usually readily separated by physical sieving or settlement. However mixtures can have different properties from the individual components. One familiar example is the mixture of fine sand with water used to make sandcastles. Neither the sand on its own nor the water on its own will make a sand-castle but by using physical properties of surface tension, the mixture behaves in a different way.

The resistance to transport in porous media increases because the viscosity of the fluid (which fills the pores) increases in the vicinity of the pore walls (Renkin effect;Renkin, EM (1954): Filtration, diffusion and molecular sieving through porous cellulose membranes. J. Gen. Physiologist., 38: 225-243 see also electroviscous effects). This effect is important in very narrow pores and in pore narrowing their diameter to the same size as the diameter of the diffusing particles.

DOI: 10.1016/j.paid.2009.05.004 In this way, the ability to understand and manage one's own emotions may play an important role in preventing children from engaging in bullying behavior. For example, in a study among adolescent girls, it was found that better management of stress could prevent the perpetuation of aggression and violence.Polan, J., Sieving, R., Pettingell, S., Bearinger, L. & McMorris, B. (2012) Relationships between adolescent girls' social-emotional intelligence and their involvement in relational aggression and physical fighting.

The species is an omnivore with specific food preferences at different life stages. During the early stages of its lifecycle, it eats mainly zooplankton, but as it grows, it eats more and more phytoplankton, and as a juvenile or adult is a herbivorous column feeder, eating mainly phytoplankton and submerged vegetation. It has modified, thin hair-like gill rakers, suggesting that it feeds by sieving the water. Rohu reach sexual maturity between two and five years of age.

They carry heavy bags of mud with their heads to designated sieving and washing sites. Children suffer the effects of noise, vibration, overexertion, poor ventilation, and exhaustion. Children’s lives are put at risk by rock fall, explosions, the collapsing of tunnels and mine shafts, falling into open shafts and pits, and breathing air polluted by dust and toxic gas. Having immune systems that are not fully developed makes children especially vulnerable to dust and chemical exposure.

Mineral processing begins with beneficiation, consisting of initially breaking down the ore to required sizes depending on the concentration process to be followed, by crushing, grinding, sieving etc. Thereafter, the ore is physically separated from any unwanted impurity, depending on the form of occurrence and or further process involved. Separation processes take advantage of physical properties of the materials. These physical properties can include density, particle size and shape, electrical and magnetic properties, and surface properties.

As is common for Albanerpetontids, the remains of Anoualerpeton all come from so-called microvertebrate localities, i.e. isolated, relatively small bones obtained by slurrying and sieving samples of the sedimentary rock in which they were embedded. So far, Anoualerpeton is only known from the type localities of the two species. The older species Anoualerpeton priscus originates from the Kirtlington Mammal Bed ("Kirtlington mammal layer") in the lowest part of the Forest Marble Formation of the Bathonian of Central England.

Microfluidic sample separation can be achieved by capillary electrophoresis or continuous-flow separation. In capillary electrophoresis, a long thin tube separates analytes by voltage as they migrate by electro- osmotic flow. For continuous-flow separation, the general idea is to apply a field at an angle to the flow direction to deflect the sample flow path toward different channels. Examples of continuous-flow separation techniques include continuous-flow electrophoresis, isoelectric focusing, continuous-flow magnetic separations, and molecular sieving.

Larva in its underwater habitat Caddisfly larvae can be found in all feeding guilds in freshwater habitats. Most early stage larvae and some late stage ones are collector- gatherers, picking up fragments of organic matter from the benthos. Other species are collector-filterers, sieving organic particles from the water using silken nets, or hairs on their legs. Some species are scrapers, feeding on the film of algae and other periphyton that grows on underwater objects in sunlight.

This algorithm, as mentioned above, is very efficient for numbers of the form re±s, for r and s relatively small. It is also efficient for any integers which can be represented as a polynomial with small coefficients. This includes integers of the more general form are±bsf, and also for many integers whose binary representation has low Hamming weight. The reason for this is as follows: The Number Field Sieve performs sieving in two different fields.

Sieveking travels to New York to see Pohl and attend a David Lynch Foundation press conference featuring Paul McCartney and Ringo Starr. After some negotiation, Sieving is able to meet again with Lynch who addresses Sieveking's skepticism about TM's herbal business and meditation organization. Later, Pohl argues with Sieveking on a train ride and accuses him of being "obsessed" with the TM movement and of "harassing" Lynch. After a walk on the beach they end their romantic relationship.

Sieving of captured insects is done to remove 'biko (insect wings) and taken to the market. For the remaining ants at home, oni (stones) are picked out and ants cooked with ai (salt) before being eaten straight away or dried in the sun for future consumption. Ombangulu (casually regarded as "Lugbara pizza") is made by pounding wingless onya, adding salt and cooking in leaves (like from banana plants). It can also be called bofolo; ombangulu literally means "toughened or compacted together".

The young navvy (shovelling soil) and the older navvy (sieving quicklime) The principal figure of the young workman is shovelling soil from a platform hanging in a hole onto a large pile behind him. Beneath him in the underground shaft another workman is digging the soil and shovelling it onto the platform. He is only visible in the form of a hand and a shovel appearing from the hole. To his right an older navvy is seen shovelling unsifted lime into a sieve.

It gets its efficiency by eschewing binary arithmetic for an "optical" adder which can add hundreds of thousands of quantities in a single clock cycle. The key idea used is "time-space inversion". Conventional NFS sieving is carried out one prime at a time. For each prime, all the numbers to be tested for smoothness in the range under consideration which are divisible by that prime have their counter incremented by the logarithm of the prime (similar to the sieve of Eratosthenes).

Woven wire cloth, typically produced from stainless steel, is commonly employed as a filtration medium for sieving in a wide range of industries. Most often woven with a plain weave, or a twill weave for the lightest of meshes, apertures can be produced from a few microns upwards (e.g. 25 microns), employing wires with diameters from as little as 25 microns. A twill weave allows a mesh to be woven when the wire diameter is too thick in proportion to the aperture.

NEI Director Paul A. Sieving, M.D., Ph.D. Image of Dr. Carl Kupfer By the National Eye Institute Organizing, structuring, and separating vision and neurological research was a challenge at NINDB. NIH did its best to provide an equal budget plan for separate funding for vision research within NINDB. But there was not enough support and staff to handle more projects then what they were already undertaking. This led to the vision research program losing sufficient funding compared to the neurological research program.

In 1983, Suczek published a journal article on Disaggregation of quartzites in the Journal of Sedimentary Petrology. She explained that the common method of analyzing grain sizes was through sieving and that this method was very time-consuming and the results are not accurate (apart from the median and graphic means). Instead, she proposed and described a method where the cement is dissolved by hydrofluoric acid to isolate the quartzites. She built this off of a model developed by Pessagno and Newport.

Gyratory equipment, used in mechanical screening and sieving is based on a circular motion of the machine. Unlike other methods, gyratory screen operates in a gentler manner and is more suited to handle fragile things, enabling it to produce finer products. This method is applicable for both wet and dry screening. A distinct difference to other techniques is that the gyratory motion applied here depends on eccentric weights instead of vibrations, which can be varied based on individual process requirement.

Fruits with tart-sweet flavor and higher pectin content, such as Korean cherry, Chinese quince, apricot, mountain hawthorn, bokbunja, Oriental cherry, bog blueberry and magnolia berry are preferred for making gwapyeon. The jelly can be made by boiling any of the above fruits in water, sieving it, then adding honey and simmering it for a long time on low heat. Starch, agar, or other gelling agents can be used as a time-saver. Boiled fruit juice is then cooled in a mold until it solidifies.

Ferroaluminum is manufactured in an electricity-intensive process that involves three steps. First, aluminium oxide (Al2O3) is obtained through the Bayer process by digestion of bauxite with sodium hydroxide (NaOH) at about 240 °C. Second, the aluminium oxide is subjected to a Hall electrolytic process together with cryolite to obtain aluminium that will then be combined with iron to create the ferroaluminum. Last, after the solidification of the metal, milling and sieving processes are carried out, which obtains the suitable particle size for its applications.

Making charas from fresh cannabis resin, Uttarakhand, India The sticky resins of the fresh flowering female cannabis plant are collected. Traditionally this was done, and still is in remote locations, by pressing or rubbing the flowering plant between two hands and then forming the sticky resins into a small ball of hashish called charas. Mechanical separation methods use physical action to remove the trichomes from the dried plant material, such as sieving through a screen by hand or in motorized tumblers. This technique is known as "drysifting".

150px Maintenance costs can be significantly reduced if an operation focuses on the fragmentation of the particles passing through their process. Automated sieving systems can detect and help remove any oversize material before it enters the crusher and causes maintenance problems. It also helps determine the effectiveness of the mining process prior to crushing; the sizing of material is always a critical part of operations in the mining, forestry and agricultural industries. Having an analysis taking place at every major point in an operation allows for the proper tracking of material being processed.

To produce refined (white) wheat flour, grain is usually tempered, i.e. moisture added to the grain, before milling, to optimize milling efficiency. This softens the starchy "endosperm" portion of the wheat kernel, which will be separated out in the milling process to produce what is known to consumers as white flour. The addition of moisture also stiffens the bran and ultimately reduces the energy input required to shatter the kernel, while at the same time avoiding the shattering of bran and germ particles to be separated out in this milling process by sieving or sifting.

The tiny (1.7 x 1.2 mm) snail was discovered by Frank Climo in the 1970s, but was considered to be just one form of another subterranean Hadopyrgus snail found in the Nelson area. In 2001 Martin Haase and Christina Mosimann collected more specimens from Maitai Cave by washing and sieving gravel, and using both morphological and genetic evidence realised these belonged to a distinct species. They scientifically described and named it Hadopyrgus ngataana in 2008; the name they chose, ngataana, comes from the Māori words ngata (snail or slug) and ana (cave).

A 1500 m³ storage tank of slurry, blended and prevented from settling out by a rotating arm injecting compressed air It is essential that large particles (> 150 μm for calcium carbonate and > 45 μm for quartz) should be eliminated from the rawmix, to facilitate chemical combination in the kiln. In the case of slurries, larger particles can be removed by hydrocyclones or sieving devices. These require a certain amount of energy, supplied by high pressure pumping. This process, and the moving and blending of the slurry, require careful control of the slurry viscosity.

Let C be a cyclic group generated by an element c of order n. Suppose C acts on a set X. Let X(q) be a polynomial with integer coefficients. Then the triple (X, X(q), C) is said to exhibit the cyclic sieving phenomenon (CSP) if for all integers d, the value X(e2id/n) is the number of elements fixed by cd. In particular X(1) is the cardinality of the set X, and for that reason X(q) is regarded as a generating function for X.

Similarly, s = be·g(a/b) is an integer. The goal is to find integer values of a and b that simultaneously make r and s smooth relative to the chosen basis of primes. If a and b are small, then r and s will be small too, about the size of m, and we have a better chance for them to be smooth at the same time. The current best-known approach for this search is lattice sieving; to get acceptable yields, it is necessary to use a large factor base.

To summarize, the basic quadratic sieve algorithm has these main steps: # Choose a smoothness bound B. The number π(B), denoting the number of prime numbers less than B, will control both the length of the vectors and the number of vectors needed. # Use sieving to locate π(B) + 1 numbers ai such that bi=(ai2 mod n) is B-smooth. #Factor the bi and generate exponent vectors mod 2 for each one. # Use linear algebra to find a subset of these vectors which add to the zero vector.

Palaeontologists sieving for fossils in the Manuherikia River The town lends its name to the St Bathans fauna, a rich palaeontological section of the lower Bannockburn Formation of the Manuherikia Group, with an age range of 19–16 million years ago. The layer in which the fossils are found derives from littoral zone sediments deposited in a large shallow freshwater lake bordered by an extensive floodplains. The fossiliferous layer has been exposed at places along the Manuherikia River close to the town, and is the remnant of the prehistoric Lake Manuherikia.

Just less than five gigabytes of disk storage was required and about 2.5 gigabytes of RAM for the sieving process. Rivest, Shamir, and Adleman noted that Miller has shown that – assuming the truth of the Extended Riemann Hypothesis – finding d from n and e is as hard as factoring n into p and q (up to a polynomial time difference). However, Rivest, Shamir, and Adleman noted, in section IX/D of their paper, that they had not found a proof that inverting RSA is equally as hard as factoring.

Sediment or rock samples are collected from either cores or outcrops, and the microfossils they contain are extracted by a variety of physical and chemical laboratory techniques, including sieving, density separation by centrifuge or in heavy liquids, and chemical digestion of the unwanted fraction. The resulting concentrated sample of microfossils is then mounted on a slide for analysis, usually by light microscope. Taxa are then identified and counted. The enormous numbers of microfossils that a small sediment sample can often yield allows the collection of statistically robust datasets which can be subjected to multivariate analysis.

The idea of promession involves five steps: # Coffin separation: the body is placed into the chamber # Cryogenic freezing: liquid nitrogen at −196 °C crystallizes the body # Vibration: the body is disintegrated into particles within minutes # Freeze drying: particles are freeze dried in a drying chamber, leaving approximately 30% of the original weight # Metal separation: any metals (e.g., tooth amalgam, artificial hips, etc.) are removed, either by magnetism or by sieving. The dry powder is placed in a biodegradable casket which is interred in the top layers of soil, where aerobic bacteria decompose the remains into humus in as little as 6–12 months.

Sieving's team, in coordination with the clinical staff at the National Institutes of Health Clinical Center, is conducting a phase 1 clinical trial to test the therapy in XLRS patients. He maintains a small clinical practice at NEI for patients with these and other genetic retinal diseases, including Stargardt juvenile macular degeneration. Sieving established the NEI Audacious Goals Initiative (AGI) for Regenerative Medicine, a major program to develop treatments for eye diseases. The AGI is a strategic research effort to restore function of critical nerve cells in the eye and visual system even after they are damaged by disease.

Paul Pritchard, Explaining the wheel sieve, Acta Informatica 17 (1982), 477–485. Paul Pritchard, Fast compact prime number sieves (among others), Journal of Algorithms 4 (1983), 332–344. Pritchard observed that for the wheel sieves, one can reduce memory consumption while preserving Big O time complexity, but this generally comes at a cost in an increased constant factor for time per operation due to the extra complexity. Therefore, this special version is likely more of value as an intellectual exercise than a practical prime sieve with reduced real time expended for a given large practical sieving range.

Making fish paste in Cambodia Fish paste is fish which has been chemically broken down by a fermentation process until it reaches the consistency of a soft creamy purée or paste. Alternatively it refers to cooked fish which has been physically broken down by pounding, grinding, pressing, mincing, blending, and/or sieving, until it reaches the consistency of paste. The term can be applied also to shellfish pastes, such as shrimp paste or crab paste. Fish paste is used as a condiment or seasoning to add flavour to food, or in some cases to complement a dish.

The generation must be initiated only when the prime's square is reached, to avoid adverse effects on efficiency. It can be expressed symbolically under the dataflow paradigm as primes = [2, 3, ...] \ p², p²+p, ...] for p in primes], using list comprehension notation with `\` denoting set subtraction of arithmetic progressions of numbers. Primes can also be produced by iteratively sieving out the composites through divisibility testing by sequential primes, one prime at a time. It is not the sieve of Eratosthenes but is often confused with it, even though the sieve of Eratosthenes directly generates the composites instead of testing for them.

Ghana National Agricultural Export is the agricultural arm of the government of Ghana Republic aimed at exporting major agricultural nuts and also their growth, maintenance and care-taking. The products mainly exported by this agricultural arm of the government of the Republic of Ghana include cashew nuts, cocoa seeds/beans, peanuts, ground nuts etc. and augmented agricultural benefits from tillage as gold and red mercury. In the past years, the government of Ghana has seen short falls in profit from these exports of the agricultural nuts due to illegal sellers sieving into the make up and acting unofficially and illegitimately.

Other Mars missions collected more data, but the next dedicated mission attempt would be a sample return mission. The Russian Space Agency launched a sample return mission to Phobos in November 2011, called Fobos-Grunt. The return capsule also included a life science experiment of The Planetary Society, called Living Interplanetary Flight Experiment, or LIFE. A second contributor to this mission was the China National Space Administration, which supplied a surveying satellite called "Yinghuo-1", which would have been released in the orbit of Mars, and a soil-grinding and sieving system for the scientific payload of the Phobos lander.

A beverage made from apple vinegar in China Several beverages are made using vinegar, for instance Posca in ancient Rome. The ancient Greek drink oxymel is made from vinegar and honey, and sekanjabin is a traditional Persian drink similar to oxymel. Other preparations, known colloquially as "shrubs", range from simply mixing sugar water or honey water with small amounts of fruity vinegar, to making syrup by laying fruit or mint in vinegar for several days, then sieving off solid parts and adding considerable amounts of sugar. Some prefer to boil the "shrub" as a final step.

The aim of barley cleaning is to remove foreign matter (straw, chaff, dust and thin corns) found in the incoming grain, leaving only the grain most likely to produce a good malt. Magnets are used to remove metals from the grain, in turn reducing the possibility of sparks, which could lead to a dust explosion. Rotating and shaking sieves are used to remove unwanted foreign matter either larger (straw and un-threshed ears) or smaller (sand and thin corns) than the normal barley grain. During the sieving process an aspiration system removes the dust and chaff.

As Bengali kitchens as a principle would not let anything go to waste, the coarse pulp left behind after sieving the mustard was finely ground again and mixed with more mustard to make what is know as phool kasundi. This was also regarded as a part of the rites of making kasundi. With phool kasundi, more chilli, turmeric, green mango and salt were added to make a grainier, bolder, fuller-bodied and spicier sauce. The rest of the process was similar to regular kasundi, except in households where Brahmins made the kasundi the women of the household would make phool kasundi.

12151 − 1, of 542 bits (163 digits), was factored between April and July 1993 by a team at CWI and Oregon State University. 2773 + 1, of 774 bits (233 digits), was factored between April and November 2000 by 'The Cabal', with the matrix step done over 250 hours on the Cray also used for RSA-155. 2809 − 1, of 809 bits (244 digits), had its factorisation announced at the start of January 2003. Sieving was done at the CWI, at the Scientific Computing Institute and the Pure Mathematics Department at Bonn University, and using private resources of J. Franke, T. Kleinjung and the family of F. Bahr.

Gypsum waste can be turned into recycled gypsum by processing the gypsum waste in such a way that the contaminants are removed and the paper facing of the plasterboard is separated from the gypsum core through mechanical processes including grinding and sieving in specialised equipment. Gypsum waste such as gypsum blocks and plaster do not require the removal of paper, as they are not made with paper from the beginning. It is typical for the gypsum recyclers to accept up to 3 per cent of contamination from other materials. The professional recyclers are capable of handling gypsum waste with nails and screws, wall coverings etc.

A globular protein or a random coil DNA moves through the interconnected pores, and the movement of larger molecules is more likely to be impeded and slowed down by collisions with the gel matrix, and the molecules of different sizes can therefore be separated in this sieving process. The Ogston model however breaks down for large molecules whereby the pores are significantly smaller than size of the molecule. For DNA molecules of size greater than 1 kb, a reptation model (or its variants) is most commonly used. This model assumes that the DNA can crawl in a "snake-like" fashion (hence "reptation") through the pores as an elongated molecule.

Chlamys hastata, the spear scallop, spiny scallop or swimming scallop, is a species of bivalve mollusc in the family Pectinidae found on the west coast of North America from the Gulf of Alaska to San Diego, California. A limited number of these scallops are harvested by divers or by narrow trawls off the west coast of Canada. The spiny scallop lives on the seabed in the sublittoral zone between low tide mark and a depth of , on soft sediment or on rock, particularly in areas with a strong current. It is a filter feeder, sieving microscopic algae from water that passes through its gills.

Due its small size and often darker color, hammerscale is difficult to discover while carrying out simple archaeological processes, such as dry or wet sieving. Instead, when there is clear evidence that a site, such as a pit-house, involved some form of ironworking, archaeologists are advised to form a grid and collect soil from the site for further analysis. This allows for trained metallurgists to analyze the type of hammerscale and their prevalence within the structure. This is still a rare practice for lack of time or expertise, but nevertheless recommended and if untenable, soil samples should still be run over with a magnet so as to collect hammerscale flakes on site.

In 1805, a Gunpowder Works was established alongside Kinterbury Creek for the purpose of restoring damp or damaged gunpowder offloaded from ships. This hazardous process involved unpacking the powder from its barrels, assessing and sieving it, and then "restoving" it (i.e. drying the damp powder in specialized ovens) after which it would be stored in a magazine once more ready for use. At the time the main magazine lcomplex for Plymouth was at Keyham, but when land there was required for development of the Dockyard a new location was needed; so in 1852, the Board of Ordnance opened a new depot alongside the Works at St Budeaux; named Bull Point, it could accommodate up to 40,000 barrels of powder.

Entoprocts generally use one or both of: ciliary sieving, in which one band of cilia creates the feeding current and another traps food particles (the "sieve"); and downstream collecting, in which food particles are trapped as they are about to exit past them. In entoprocts, downstream collecting is carried out by the same bands of cilia that generate the current; trochozoan larvae also use downstream collecting, but use a separate set of cilia to trap food particles. In addition, glands in the tentacles secrete sticky threads that capture large particles. A non-colonial species reported from around the Antarctic Peninsula in 1993 has cells that superficially resemble the cnidocytes of cnidaria, and fire sticky threads.

The search of the solution may be made dramatically faster by sieving. For this method, we suppose, without loss of generality, that 0\le a_i (if it were not the case, it would suffice to replace each a_i by the remainder of its division by n_i). This implies that the solution belongs to the arithmetic progression :a_1, a_1 + n_1, a_1+2n_1, \ldots By testing the values of these numbers modulo n_2, one eventually finds a solution x_2 of the two first congruences. Then the solution belongs to the arithmetic progression :x_2, x_2 + n_1n_2, x_2+2n_1n_2, \ldots Testing the values of these numbers modulo n_3,, and continuing until every modulus has been tested gives eventually the solution.

The choice of polynomial can dramatically affect the time to complete the remainder of the algorithm. The method of choosing polynomials based on the expansion of in base shown above is suboptimal in many practical situations, leading to the development of better methods. One such method was suggested by Murphy and Brent; they introduce a two-part score for polynomials, based on the presence of roots modulo small primes and on the average value that the polynomial takes over the sieving area. The best reported results were achieved by the method of Thorsten Kleinjung, which allows , and searches over composed of small prime factors congruent to 1 modulo 2 and over leading coefficients of which are divisible by 60.

Over this time, Davidson managed to gather a list of native vocabularies amounting to some 4200 words, collected from informants speaking 19 different languages of Western Australia. Much of this material has yet to receive close attention from researchers. In 1938 he published A Preliminary Register of Australian Tribes and Hordes together with an An Ethnic Map of Australia, a magisterial synthesis of his close sieving of the available ethnographic materials regarding Aboriginal groups. He followed this up with a monograph in 1941 on Australian tribal string figures, exhibiting a prestidigitator's mastery for replicating such designs which he had already demonstrated in a paper he had published in a 1927 paper on string figures among the Virginian Indians.

With kilns for roasting gold bearing quartz, a sophisticated battery and dam system for crushing and washing the ore and houses for workers, the Complex provides tangible evidence of technological, social and domestic relationships during this very early stage of Australia's goldmining history. Gold bearing quartz was brought to the Complex from surrounding mines and roasted to make it easier to crush (a relatively unusual process) and then crushed in a steam powered battery. Gold was then extracted from the powdered ore through a process of sieving and washing. Despite its impressive technological achievements, the operation, managed and probably designed by Alfred Spence, was short-lived, closing in 1856, only eighteen months after it opened.

Cockle gatherers on the Llanrhidian Sands, South Wales-early morning, etching from a painting by Edward Duncan, 1849, National Library of Wales Originally, the cockles were collected by a donkey pulling a flat cart, this was replaced by pony and flat cart, and nowadays a Land Rover is used. Gathering cockles is regulated by "The Burry Inlet Cockle Fishery Order, 1965". Two grades of cockles are gathered: "boiling" cockles are smaller and cooked locally before being taken to market; "shell" cockles are larger and obtained by more intensive sieving, using larger-meshed sieves on the cockle beds. Cockles need to be thoroughly washed clean, and cooked, so it is best to buy them from a cockle producer.

Sieve theory is a set of general techniques in number theory, designed to count, or more realistically to estimate the size of, sifted sets of integers. The prototypical example of a sifted set is the set of prime numbers up to some prescribed limit X. Correspondingly, the prototypical example of a sieve is the sieve of Eratosthenes, or the more general Legendre sieve. The direct attack on prime numbers using these methods soon reaches apparently insuperable obstacles, in the way of the accumulation of error terms. In one of the major strands of number theory in the twentieth century, ways were found of avoiding some of the difficulties of a frontal attack with a naive idea of what sieving should be.

Even in PC-based implementations, it's a common optimization to speed up sieving by adding approximate logarithms of small primes together. Similarly, TWINKLE has much room for error in its light measurements; as long as the intensity is at about the right level, the number is very likely to be smooth enough for the purposes of known factoring algorithms. The existence of even one large factor would imply that the logarithm of a large number is missing, resulting in a very low intensity; because most numbers have this property, the device's output would tend to consist of stretches of low intensity output with brief bursts of high intensity output. In the above it is assumed that X is square-free, i.e.

Copper still from 19th to 20th century Grasse, France for steam distillation Fragrance extraction refers to the separation process of aromatic compounds from raw materials, using methods such as distillation, solvent extraction, expression, sieving, or enfleurage. The results of the extracts are either essential oils, absolutes, concretes, or butters, depending on the amount of waxes in the extracted product. To a certain extent, all of these techniques tend to produce an extract with an aroma that differs from the aroma of the raw materials. Heat, chemical solvents, or exposure to oxygen in the extraction process may denature some aromatic compounds, either changing their odour character or rendering them odourless, and the proportion of each aromatic component that is extracted can differ.

In January 2002, Posner worked as a member of a delegation that facilitated the first U.S. Wheat (USW) shipment to Cuba in 40 years. In addition, Posner and USW regional vice president Mitch Skalicky met with leaders of the Cuban milling sector and provided technical assistance. In 2004, he co-authored a book called Wheat Flour Milling which discussed new ideas and approaches to wheat flour milling including raw material, storage, blending, cleaning, milling, conditioning, grinding, sieving, purification, mill design, process control and maintenance as well as food safety, hygiene and mill management.Wheat Flour MIlling CabDirect, accessed April 16, 2012 Posner holds patents for a method of separating Wheat germ from whole wheat, and for a process of dry milling wheat to obtain gluten and starch.

It is very shy and difficult to see, being completely unable to enter areas without dense vegetative overstoreys,Sieving, Katharyn E, Willson, Mary F. and de Santo, Toni L.; “Defining Corridor Functions for Endemic Birds in Fragmented South-Temperate Rainforest” and cannot typically use corridors smaller than or fly further than between patches of suitable habitat.Diáz, Iván A., Willson, Mary F., Gehee, Steven M.C. & Armesto, Juan J.; “Observaciones Sobre La Biologia y Conservación del Colilarga (Sylviorthorhynchus desmursii, Furnariidae) en la Isla de Chiloé, Chile” When encountered Des Murs's wiretail can easily be mistaken for a mouse. It has the unique ability among birds to curl up its long tail into a ball when alarmed. The ball-shaped nest is made of plant fibres and built amongst vegetation close to the ground.

This makes it different from other processes such as sedimentation or diffusion where long-ranged hydrodynamic interaction are important. The gel matrix is therefore responsible for the separation of DNA by size during electrophoresis, however the precise mechanism responsible the separation is not entirely clear. A number of models exists for the mechanism of separation of biomolecules in gel matrix, a widely accepted one is the Ogston model which treats the polymer matrix as a sieve consisting of randomly distributed network of inter- connected pores. A globular protein or a random coil DNA moves through the connected pores large enough to accommodate its passage, and the movement of larger molecules is more likely to be impeded and slowed down by collisions with the gel matrix, and the molecules of different sizes can therefore be separated in this process of sieving.

The resolving gel typically has a much smaller pore size, which leads to a sieving effect that now determines the electrophoretic mobility of the proteins. At the same time, the separating part of the gel also has a pH value in which the buffer ions on average carry a greater charge, causing them to "outrun" the SDS-covered proteins and eliminate the ion gradient and thereby the stacking effect. A very widespread discontinuous buffer system is the tris-glycine or "Laemmli" system that stacks at a pH of 6.8 and resolves at a pH of ~8.3-9.0. A drawback of this system is that these pH values may promote disulfide bond formation between cysteine residues in the proteins because the pKa of cysteine ranges from 8-9 and because reducing agent present in the loading buffer doesn't co-migrate with the proteins.

In the early 1970s Hillman recognised that traditional crop-processing in the mostly unmechanised village of Asvan led to distinctive, consistent assemblages of crop seeds, chaff and weed seeds that could also be recognised in archaeobotanical samples. Contemporary analysis of archaeobotanical samples by Robin Dennell and others had recognised this variation, with the implication that ancient seed assemblages could not be treated uncritically as representative of crop use, but had not identified the close association with crop processing stages. Further fieldwork by Glynis Jones in Greece put Hillman's results onto a firmly quantified basis, and this mode of interpretation of plant remains - in terms of crop processing stages such as winnowing and sieving - is now a standard component of archaeobotany, particularly in the Old World. Many of Hillman's students carried out ethnoarchaeological work, for example Sarah Mason and Mark Nesbitt in Turkey, Catherine D'Andrea and Ann Butler in Ethiopia, and Leonor Peña-Chocarro and Lydia Zapata in Spain and Morocco.

It is also necessary to solve the quadratic equation modulo small powers of p in order to recognise numbers divisible by the square of a factor-base prime. At the end of the factor base, any A[] containing a value above a threshold of roughly log(x2-n) will correspond to a value of y(x) which splits over the factor base. The information about exactly which primes divide y(x) has been lost, but it has only small factors, and there are many good algorithms for factoring a number known to have only small factors, such as trial division by small primes, SQUFOF, Pollard rho, and ECM, which are usually used in some combination. There are many y(x) values that work, so the factorization process at the end doesn't have to be entirely reliable; often the processes misbehave on say 5% of inputs, requiring a small amount of extra sieving.

Land micromollusks are often found by taking samples of leaf litter from rich areas, subsequently sieving or sifting the litter, and then searching it under a strong light and magnification. Freshwater micromollusks which live on aquatic plants are often collected by passing a plankton net vigorously through and around water weeds so that minute mollusks end up falling into the glass tube at the end of the net. Small bottom- dwelling micromollusks such as Pisidium species are found by scooping a bottom sample of mud into a fine meshed long-handled net, and then agitating it and moving it through the water repeatedly, until only solid particles remain in the net. Because most empty land snail shells and many empty freshwater shells float, another effective way to sample dead shells from an area can be to sort through river drift, the accumulations of small floating bits and pieces left behind by creeks and rivers after floods.
