Aluminium Triacetate
Aluminium triacetate, formally named aluminium acetate, is a chemical compound with composition . Under standard conditions it appears as a white, water-soluble solid that decomposes on heating at around 200 °C. The triacetate hydrolysis, hydrolyses to a mixture of basic hydroxide / acetate salt (chemistry), salts, and multiple species co-exist in chemical equilibrium, particularly in aqueous solutions of the acetate ion; the name aluminium acetate is commonly used for this mixed system. It has therapeutic applications for its anti-itching, astringent, and antiseptic properties, and, as an over-the-counter drug, over-the-counter preparation like Burow's solution, it is used to treat otitis, ear infections. Burow's solution preparations have been diluted and modified with amino acids to make them more palatability, palatable for use as gargles for conditions like aphthous ulcers of the mouth. In veterinary medicine, aluminium triacetate's astringency property is used for t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Palatability
Palatability (or palatableness) is the hedonic reward (i.e., pleasure Pleasure refers to experience that feels good, that involves the enjoyment of something. It contrasts with pain or suffering, which are forms of feeling bad. It is closely related to value, desire and action: humans and other conscious animals ...) provided by foods or fluids that are agreeable to the "palate", which often varies relative to the homeostatic satisfaction of nutritional, Fluid balance, water, or Food energy, energy needs. The palatability of a food or fluid, unlike its Flavor (taste), flavor or taste, varies with the state of an individual: it is lower after eating, consumption and higher when hunger, deprived. It has increasingly been appreciated that this can create a hunger that is independent of homeostatic needs.Lowe MR, Butryn ML. (2007). Hedonic hunger: a new dimension of appetite? Physiol Behav.

IUPAC Nomenclature Of Inorganic Chemistry
In chemical nomenclature, the IUPAC nomenclature of inorganic chemistry is a systematic method of naming inorganic chemical compounds, as recommended by the International Union of Pure and Applied Chemistry (IUPAC). It is published in '' Nomenclature of Inorganic Chemistry'' (which is informally called the Red Book). Ideally, every inorganic compound should have a name from which an unambiguous formula can be determined. There is also an IUPAC nomenclature of organic chemistry. System The names "caffeine" and " 3,7-dihydro-1,3,7-trimethyl-1H-purine-2,6-dione" both signify the same chemical compound. The systematic name encodes the structure and composition of the caffeine molecule in some detail, and provides an unambiguous reference to this compound, whereas the name "caffeine" just names it. These advantages make the systematic name far superior to the common name when absolute clarity and precision are required. However, for the sake of brevity, even professional chemists w ...

Silk
Silk is a natural protein fiber, some forms of which can be woven into textiles. The protein fiber of silk is composed mainly of fibroin and is produced by certain insect larvae to form cocoons. The best-known silk is obtained from the cocoons of the larvae of the mulberry silkworm ''Bombyx mori'' reared in captivity ( sericulture). The shimmering appearance of silk is due to the triangular prism-like structure of the silk fibre, which allows silk cloth to refract incoming light at different angles, thus producing different colors. Silk is produced by several insects; but, generally, only the silk of moth caterpillars has been used for textile manufacturing. There has been some research into other types of silk, which differ at the molecular level. Silk is mainly produced by the larvae of insects undergoing complete metamorphosis, but some insects, such as webspinners and raspy crickets, produce silk throughout their lives. Silk production also occurs in hymenoptera ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cellulose
Cellulose is an organic compound with the formula , a polysaccharide consisting of a linear chain of several hundred to many thousands of β(1→4) linked D-glucose units. Cellulose is an important structural component of the primary cell wall of green plants, many forms of algae and the oomycetes. Some species of bacteria secrete it to form biofilms. Cellulose is the most abundant organic polymer on Earth. The cellulose content of cotton fiber is 90%, that of wood is 40–50%, and that of dried hemp is approximately 57%. Cellulose is mainly used to produce paperboard and paper. Smaller quantities are converted into a wide variety of derivative products such as cellophane and rayon. Conversion of cellulose from energy crops into biofuels such as cellulosic ethanol is under development as a renewable fuel source. Cellulose for industrial use is mainly obtained from wood pulp and cotton. Some animals, particularly ruminants and termites, can digest cellulose wit ...

Cotton
Cotton is a soft, fluffy staple fiber that grows in a boll, or protective case, around the seeds of the cotton plants of the genus '' Gossypium'' in the mallow family Malvaceae. The fiber is almost pure cellulose, and can contain minor percentages of waxes, fats, pectins, and water. Under natural conditions, the cotton bolls will increase the dispersal of the seeds. The plant is a shrub native to tropical and subtropical regions around the world, including the Americas, Africa, Egypt and India. The greatest diversity of wild cotton species is found in Mexico, followed by Australia and Africa. Cotton was independently domesticated in the Old and New Worlds. The fiber is most often spun into yarn or thread and used to make a soft, breathable, and durable textile. The use of cotton for fabric is known to date to prehistoric times; fragments of cotton fabric dated to the fifth millennium BC have been found in the Indus Valley civilization, as well as fabric remnants dat ...

Aluminium Sulfacetate
Aluminium sulfacetate is a mixture of aluminium salts dissolved in water with formula . Uses It is an evenly balanced mixture of aluminium sulfate and aluminium acetate. It can be used as a mordant, which is a substance used to set dyes on fabrics that typically contains a polyvalent metal ion like aluminium or iron, In mixtures with basic aluminium diacetate or aluminium sulfacetate, aluminium triacetate has been used as a mordant with alizarin dye. In 1899, Albert Ganswindt recommended that the use of impure sulfacetates that are empyreumatic liquids "should be abandoned" in favour of pure preparations. Empyreuma is an obsolete chemical and medical term referring to "the smell and taste associated with burning vegetable and animal matter", and likely results in this case from the use of pyroligneous acid (wood acid) or wood acid lime in the preparation of the mordant. Preparation A common approach to preparing aluminium sulfacetate is by reaction of aluminium sulfate with ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Alizarin
Alizarin (also known as 1,2-dihydroxyanthraquinone, Mordant Red 11, C.I. 58000, and Turkey Red) is an organic compound with formula that has been used throughout history as a prominent red dye, principally for dyeing textile fabrics. Historically it was derived from the roots of plants of the madder genus.The primary madder species from which alizarin historically has been obtained is ''Rubia tinctorum''. See also In 1869, it became the first natural dye to be produced synthetically. Alizarin is the main ingredient for the manufacture of the madder lake pigments known to painters as rose madder and alizarin crimson. Alizarin in the most common usage of the term has a deep red color, but the term is also part of the name for several related non-red dyes, such as Alizarine Cyanine Green and Alizarine Brilliant Blue. A notable use of alizarin in modern times is as a staining agent in biological research because it stains free calcium and certain calcium compounds a red or ligh ...

Mordant
A mordant or dye fixative is a substance used to set (i.e. bind) dyes on fabrics by forming a coordination complex with the dye, which then attaches to the fabric (or tissue). It may be used for dyeing fabrics or for intensifying stains in biological specimen, cell or tissue preparations. Although mordants are still used, especially by small batch dyers, it has been largely displaced in industry by substantive dye, directs.} The term mordant comes from the Latin ''mordere'', "to bite". In the past, it was thought that a mordant helped the dye bite onto the fiber so that it would hold fast during washing. A mordant is often a polyvalency (chemistry), polyvalent metal ion, and one example is chromium (III). The resulting coordination complex of dye and ion is colloidal and can be either acidic or base (chemistry), alkaline. Common dye mordants Mordants include tannic acid, oxalic acid, alum, chrome alum, sodium chloride, and certain salt (chemistry), salts of aluminium, chrom ...

Mortellaro Disease
Digital dermatitis is a disease that causes lameness in cattle. It was first discovered in Italy in 1974 by Cheli and Mortellaro. This disease is caused by a mixture of different bacteria. Anaerobic bacteria, including spirochetes of the genus ''Treponema'', are found in the lesions associated with the infection. Digital dermatitis is different from foot rot in cattle and both conditions may occur concurrently. Digital dermatitis primarily affects dairy cattle and has been known to lower the quantity of milk produced, but the quality of the milk is unaffected. Evidence shows that risk factors favouring digital dermatitis outbreaks include: poor hygiene and high humidity; introduction of infected animals; no hoof care for heifers and dry cows; high levels of chronically infected animals; insufficient or inadequate hoof trimming; soft hooves and unbalanced nutrition. Presentation Digital dermatitis appears as lesions which initially looks like a raw, red, oval ulcer on the back ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
