Resale price maintenanceResale price maintenance (RPM) or, occasionally, retail price maintenance is the practice whereby a manufacturer and its distributors agree that the distributors will sell the manufacturer's product at certain prices (resale price maintenance), at or above a price floor (minimum resale price maintenance) or at or below a price ceiling (maximum resale price maintenance). If a reseller refuses to maintain prices, either openly or covertly (see grey market), the manufacturer may stop doing business with it.
KeteneIn organic chemistry, a ketene is an organic compound of the form , where R and R' are two arbitrary monovalent chemical groups (or two separate substitution sites in the same molecule). The name may also refer to the specific compound ethenone , the simplest ketene. Although they are highly useful, most ketenes are unstable. When used as reagents in a chemical procedure, they are typically generated when needed, and consumed as soon as (or while) they are produced. Ketenes were first studied as a class by Hermann Staudinger before 1905.
StarchStarch or amylum is a polymeric carbohydrate consisting of numerous glucose units joined by glycosidic bonds. This polysaccharide is produced by most green plants for energy storage. Worldwide, it is the most common carbohydrate in human diets, and is contained in large amounts in staple foods such as wheat, potatoes, maize (corn), rice, and cassava (manioc). Pure starch is a white, tasteless and odorless powder that is insoluble in cold water or alcohol. It consists of two types of molecules: the linear and helical amylose and the branched amylopectin.
DiarrheaDiarrhea, also spelled diarrhoea or diarrhœa, is the condition of having at least three loose, liquid, or watery bowel movements each day. It often lasts for a few days and can result in dehydration due to fluid loss. Signs of dehydration often begin with loss of the normal stretchiness of the skin and irritable behaviour. This can progress to decreased urination, loss of skin color, a fast heart rate, and a decrease in responsiveness as it becomes more severe. Loose but non-watery stools in babies who are exclusively breastfed, however, are normal.
Chemistry of ascorbic acidAscorbic acid is an organic compound with formula C6H8O6, originally called hexuronic acid. It is a white solid, but impure samples can appear yellowish. It dissolves well in water to give mildly acidic solutions. It is a mild reducing agent. Ascorbic acid exists as two enantiomers (mirror-image isomers), commonly denoted "" (for "levo") and "" (for "dextro"). The isomer is the one most often encountered: it occurs naturally in many foods, and is one form ("vitamer") of vitamin C, an essential nutrient for humans and many animals.
GastroenteritisGastroenteritis, also known as infectious diarrhea or simply as gastro, is an inflammation of the gastrointestinal tract including the stomach and intestine. Symptoms may include diarrhea, vomiting, and abdominal pain. Fever, lack of energy, and dehydration may also occur. This typically lasts less than two weeks. Although it is not related to influenza, in the U.S. it is sometimes called the "stomach flu". Gastroenteritis is usually caused by viruses; however, gut bacteria, parasites, and fungi can also cause gastroenteritis.
Tosyl groupIn organic chemistry, a toluenesulfonyl group (tosyl group, abbreviated Ts or Tos) is a univalent functional group with the chemical formula . It consists of a tolyl group, , joined to a sulfonyl group, , with the open valence on sulfur. This group is usually derived from the compound tosyl chloride, (abbreviated TsCl), which forms esters and amides of toluenesulfonic acid, (abbreviated TsOH). The para orientation illustrated (p-toluenesulfonyl) is most common, and by convention tosyl without a prefix refers to the p-toluenesulfonyl group.
Currency warCurrency war, also known as competitive devaluations, is a condition in international affairs where countries seek to gain a trade advantage over other countries by causing the exchange rate of their currency to fall in relation to other currencies. As the exchange rate of a country's currency falls, exports become more competitive in other countries, and imports into the country become more and more expensive. Both effects benefit the domestic industry, and thus employment, which receives a boost in demand from both domestic and foreign markets.
Current account (balance of payments)In economics, a country's current account records the value of exports and imports of both goods and services and international transfers of capital. It is one of the two components of its balance of payments, the other being the capital account (also known as the financial account). Current account measures the nation's earnings and spendings abroad and it consists of the balance of trade, net primary income or factor income (earnings on foreign investments minus payments made to foreign investors) and net unilateral transfers, that have taken place over a given period of time.
BioproductBioproducts or bio-based products are materials, chemicals and energy derived from renewable biological material. Biological resources include agriculture, forestry, and biologically derived waste, and there are many other renewable bioresource examples. One of the examples of renewable bioresources is lignocellulose. Lignocellulosic tissues are biologically derived natural resources containing some of the main constituents of the natural world.
