Amino Acid
Amino acids are organic compounds that contain both amino and carboxylic acid functional groups. Although over 500 amino acids exist in nature, by far the most important are the 22 α-amino acids incorporated into proteins. Only these 22 appear in the genetic code of life. Amino acids can be classified according to the locations of the core structural functional groups ( alpha- , beta- , gamma- amino acids, etc.); other categories relate to polarity, ionization, and side-chain group type ( aliphatic, acyclic, aromatic, polar, etc.). In the form of proteins, amino-acid '' residues'' form the second-largest component (water being the largest) of human muscles and other tissues. Beyond their role as residues in proteins, amino acids participate in a number of processes such as neurotransmitter transport and biosynthesis. It is thought that they played a key role in enabling life on Earth and its emergence. Amino acids are formally named by the IUPAC- IUBMB Joint Commi ...

Crop Residue
Crop residues are waste materials generated by agriculture. The two types are: * Field residues are materials left in an agricultural field or orchard after the crop has been harvested. These residues include stalks and stubble (stems), leaves and seed pods. Good management of field residues can increase efficiency of irrigation and control of erosion. The residue can be ploughed directly into the ground, or burned first. In contrast, no-till, strip-till or reduced-till agriculture practices are carried out to maximize crop residue cover. * Process residues are materials left after the crop is processed into a usable resource. These residues include husks, seeds, bagasse, molasses and roots. They can be used as animal fodder and soil amendment, fertilizers and in manufacturing. Measurements Simple line-transect measurements can be used to estimate residue coverage. The amount of crop residues can also be estimated using photographic techniques, or remote sensi ...

Pesticide Residue
Pesticide residue refers to the pesticides that may remain on or in food, after they are applied to food crops. The maximum allowable levels of these residues in foods are stipulated by regulatory bodies in many countries. Regulations such as pre-harvest intervals also prevent harvest of crop or livestock products if recently treated in order to allow residue concentrations to decrease over time to safe levels before harvest. Definition A pesticide is a substance or a mixture of substances used for killing pests: organisms dangerous to cultivated plants or to animals. The term applies to various pesticides such as insecticides, fungicides, herbicides and nematocides. The definition of residue of pesticide according to the World Health Organization (WHO) is: Any specified substances in or on food, agricultural commodities or animal feed resulting from the use of a pesticide. The term includes any derivatives of a pesticide, such as conversion products, metabolites, reaction pr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Oil Refinery
An oil refinery or petroleum refinery is an industrial processes, industrial process Factory, plant where petroleum (crude oil) is transformed and refining, refined into products such as gasoline (petrol), diesel fuel, Bitumen, asphalt base, fuel oils, heating oil, kerosene, liquefied petroleum gas and petroleum naphtha. Petrochemical feedstock like ethylene and propene, propylene can also be produced directly by Cracking (chemistry), cracking crude oil without the need of using refined products of crude oil such as naphtha. The crude oil feedstock has typically been processed by an oil production plant. There is usually an oil depot at or near an oil refinery for the storage of incoming crude oil feedstock as well as bulk liquid products. In 2020, the total capacity of global refineries for crude oil was about 101.2 million barrels per day. Oil refineries are typically large, sprawling industrial complexes with extensive piping running throughout, carrying streams of fluids b ...

Residue (chemistry)
In chemistry, residue is whatever remains or acts as a contaminant after a given class of events. Residue may be the material remaining after a process of preparation, separation, or purification, such as distillation, evaporation, or filtration. It may also denote the undesired by-products of a chemical reaction. Residues as an undesired by-product are a concern in agricultural and food industries. Food safety Toxic chemical residues, wastes or contamination from other processes, are a concern in food safety. The most common food residues originate from pesticides, veterinary drugs, and industrial chemicals. For example, the U.S. Food and Drug Administration (FDA) and the Canadian Food Inspection Agency (CFIA) have guidelines for detecting chemical residues that are possibly dangerous to consume. In the U.S., the FDA is responsible for setting guidelines while other organizations enforce them. Environmental concerns Similar to the food industry, in environmental science ...

Residue (complex Analysis)
In mathematics, more specifically complex analysis, the residue is a complex number proportional to the contour integral of a meromorphic function along a path enclosing one of its singularities. (More generally, residues can be calculated for any function f\colon \mathbb \setminus \_k \rightarrow \mathbb that is holomorphic except at the discrete points ''k'', even if some of them are essential singularities.) Residues can be computed quite easily and, once known, allow the determination of general contour integrals via the residue theorem. Definition The residue of a meromorphic function f at an isolated singularity a, often denoted \operatorname(f,a), \operatorname_a(f), \mathop_f(z) or \mathop_f(z), is the unique value R such that f(z)- R/(z-a) has an analytic antiderivative in a punctured disk 0<\vert z-a\vert<\delta. Alternatively, residues can be calculated by finding |
Partial Fraction Decomposition
In algebra, the partial fraction decomposition or partial fraction expansion of a rational fraction (that is, a fraction such that the numerator and the denominator are both polynomials) is an operation that consists of expressing the fraction as a sum of a polynomial (possibly zero) and one or several fractions with a simpler denominator. The importance of the partial fraction decomposition lies in the fact that it provides algorithms for various computations with rational functions, including the explicit computation of antiderivatives, Taylor series expansions, inverse Z-transforms, and inverse Laplace transforms. The concept was discovered independently in 1702 by both Johann Bernoulli and Gottfried Leibniz. In symbols, the ''partial fraction decomposition'' of a rational fraction of the form \frac, where and are polynomials, is the expression of the rational fraction as \frac=p(x) + \sum_j \frac where is a polynomial, and, for each , the denominator is a power of ...

Modular Arithmetic
In mathematics, modular arithmetic is a system of arithmetic operations for integers, other than the usual ones from elementary arithmetic, where numbers "wrap around" when reaching a certain value, called the modulus. The modern approach to modular arithmetic was developed by Carl Friedrich Gauss in his book '' Disquisitiones Arithmeticae'', published in 1801. A familiar example of modular arithmetic is the hour hand on a 12-hour clock. If the hour hand points to 7 now, then 8 hours later it will point to 3. Ordinary addition would result in , but 15 reads as 3 on the clock face. This is because the hour hand makes one rotation every 12 hours and the hour number starts over when the hour hand passes 12. We say that 15 is ''congruent'' to 3 modulo 12, written 15 ≡ 3 (mod 12), so that 7 + 8 ≡ 3 (mod 12). Similarly, if one starts at 12 and waits 8 hours, the hour hand will be at 8. If one instead waited twice as long, 16 hours, the hour hand would be on 4. This ca ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Residue (TV Series)
''Residue'' is a British science fiction supernatural horror miniseries created and written by John Harrison and directed by Alex García López. The first series, which consists of three episodes of 44 minutes each, entirely premiered on 31 March 2015 on the streaming service Netflix. ''Residue'' revolves around the aftermath of an explosion in an English futuristic metropolis nightclub and the unreliable quarantine zone built by the government, who is hiding what is really happening inside it. In the meantime, a photojournalist (portrayed by Natalia Tena) stumbles upon paranormal events triggered either by or after the bombing. In 2015 producer Charlotte Walls stated that there were plans for a 10-episodes second season, for which Netflix would have the exclusive option. As of 2018, there has been no further news.

And I Have Been
''And I Have Been'' is the third studio album by English composer, musician, and poet Benjamin Clementine. It was released through his own label Preserve Artists on 28 October 2022. The album was entirely written, performed, produced, and mixed by Clementine. The album was promoted by the singles "Copening", "Weakend", "Genesis" and "Delighted". Background and recording Clementine's second studio album '' I Tell a Fly'' was released in July 2017 to critical acclaim, but its stylistic deviation also polarized listeners. In 2019, Clementine was conferred Knight of the Order of Arts and Letters by the French government. In 2021, Clementine made his acting debut in Denis Villeneuve's epic science fiction film ''Dune''. ''And I Have Been'' was conceived during the COVID-19 pandemic while Clementine was living up in the Santa Monica Mountains and in the small town of Ojai, California. In a press release Clementine said he was "confronted with a lot of lessons, complications and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Levy-Dew
"Levy-Dew", also known as "A New Year Carol" and "Residue", is a British folk song of Welsh origin traditionally sung in New Year celebrations. It is associated with a New Year's Day custom involving sprinkling people with water newly drawn from a well. The song was set to music by Benjamin Britten in 1934. Lyric As with any traditional folk song, there are a number of variations. What is now regarded as the standard version is attested from 1849 onwards. Substantially the same wording was included by Walter de la Mare in '' Tom Tiddler's Ground'' (1931), an anthology of verse for children. De la Mare's version runs: Benjamin Britten set the De la Mare version of the song to music as "A New Year Carol" in 1934. Traditions The song is associated with Pembrokeshire. There, it figured in a custom in which, on New Year's Day, children collect fresh water from a well, and go around with a sprig from an evergreen tree, which they use to sprinkle the faces of passers-by with the w ...

Residuum (geology)
Residuum is weathered rock that is not transported by erosion, contributing in time to the formation of soil. It is distinguished from other types of parent material in that it is composed solely of mineral, not organic, material, and it remains in place rather than being moved by the action of wind, water, or gravity. Characteristics Parent material is one of the soil forming factors defined as “unconsolidated organic and mineral materials in which soils form”. Making parent material an important part of the soil forming process. The other soil forming factors are climate, organisms, relief and time. Parent materials that are not residual are classified by their mode of transport into a system. These modes of transport are by wind ( aeolian), water, gravity (colluvial), ice (glacial till), lakes (lacustrine), oceans ( marine) or in place (non transported). Soils derived from residuum are called residual soils. These soils are expected to be mineralogically similar to their un ...
