Order Of The British Empire
The Most Excellent Order of the British Empire is a British order of chivalry, rewarding contributions to the arts and sciences, work with charitable and welfare organisations, and public service outside the civil service. It was established on 4 June 1917 by King George V and comprises five classes across both civil and military divisions, the most senior two of which make the recipient either a knight if male or dame if female. There is also the related British Empire Medal, whose recipients are affiliated with, but not members of, the order. Recommendations for appointments to the Order of the British Empire were originally made on the nomination of the United Kingdom, the self-governing Dominions of the Empire (later Commonwealth) and the Viceroy of India. Nominations continue today from Commonwealth countries that participate in recommending British honours. Most Commonwealth countries ceased recommendations for appointments to the Order of the British Empire when they ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Wandsworth School
Wandsworth School was a local authority maintained boys' secondary school in Southfields, London. Established in 1895, it became a selective grammar school, then an all-ability comprehensive school, before merging in 1986 and finally closing in 1991. From the 1960s it became well known for its choir. History Wandsworth School was founded in 1895 as a Day Science School in adapted premises in Wandsworth High Street, and was renamed ''Wandsworth Technical Institute Secondary School'' in 1900. After the passing of the Education Act 1902 the school developed an academic based grammar school curriculum, and in 1908 became the ''Wandsworth County School''. Initially co-educational, the School became boys-only when Mayfield Girls Grammar School opened in 1909.How your House got its name. ''The Link, School Magazine''. Pages 39-40. Spring 1973. By 1920 the school had over 500 boys and was one of the largest grammar schools in London. [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Flamingo
Flamingos or flamingoes are a type of Wader, wading bird in the Family (biology), family Phoenicopteridae, which is the only extant family in the order Phoenicopteriformes. There are four flamingo species distributed throughout the Americas (including the Caribbean), and two species native to Afro-Eurasia. A group of flamingoes is called a "flamboyance." Etymology The name ''flamingo'' comes from Portuguese language, Portuguese or Spanish language, Spanish ("flame-colored"), which in turn comes from Old Occitan, Provençal – a combination of ("flame") and a Germanic-like suffix ''wikt:-ing#Etymology 3, -ing''. The word may also have been influenced by the Spanish ethnonym ("Fleming" or "Flemish"). The name of the genus, ''Phoenicopterus'', is from the Greek , ); other genera names include ''Lesser flamingo, Phoeniconaias,'' which means "crimson/red Naiad, water nymph (or naiad)", and ''Phoenicoparrus,'' which means "crimson/red bird (though, an unknown bird of om ...

Wittig Reaction
The Wittig reaction or Wittig olefination is a chemical reaction of an aldehyde or ketone with a triphenyl phosphonium ylide called a Wittig reagent. Wittig reactions are most commonly used to convert aldehydes and ketones to alkenes. Most often, the Wittig reaction is used to introduce a methylene group using methylenetriphenylphosphorane (Ph3P=CH2). Using this reagent, even a sterically hindered ketone such as camphor can be converted to its methylene derivative. Stereochemistry For the reaction with aldehydes, the double bond geometry is readily predicted based on the nature of the ylide. With unstabilised ylides (R3 = alkyl) this results in (''Z'')-alkene product with moderate to high selectivity. With stabilized ylides (R3 = ester or ketone), the (''E'')-alkene is formed with high selectivity. The (''E'')/(''Z'') selectivity is often poor with semistabilized ylides (R3 = aryl). To obtain the (''E'')-alkene for unstabilized ylides, the Schlosser modification of the W ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Iodine
Iodine is a chemical element with the symbol I and atomic number 53. The heaviest of the stable halogens, it exists as a semi-lustrous, non-metallic solid at standard conditions that melts to form a deep violet liquid at , and boils to a violet gas at . The element was discovered by the French chemist Bernard Courtois in 1811 and was named two years later by Joseph Louis Gay-Lussac, after the Ancient Greek 'violet-coloured'. Iodine occurs in many oxidation states, including iodide (I−), iodate (), and the various periodate anions. It is the least abundant of the stable halogens, being the sixty-first most abundant element. As the heaviest essential mineral nutrient, iodine is required for the synthesis of thyroid hormones. Iodine deficiency affects about two billion people and is the leading preventable cause of intellectual disabilities. The dominant producers of iodine today are Chile and Japan. Due to its high atomic number and ease of attachment to organic compound ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bixa Orellana
''Bixa orellana'', also known as achiote, is a shrub native to Central America. ''Bixa orellana'' is grown in many countries worldwide. The tree is best known as the source of annatto, a natural orange-red condiment (also called or ) obtained from the waxy arils that cover its seeds. The ground seeds are widely used in traditional dishes in Central and South America, Mexico, and the Caribbean, such as ''cochinita pibil'', chicken in , , and . Annatto and its extracts are also used as an industrial food coloring to add yellow or orange color to many products such as butter, cheese, margarine, ice creams, meats, and condiments. Some of the indigenous peoples of North, Central, and South American originally used the seeds to make red body paint and lipstick, as well as a spice. For this reason, the ''Bixa orellana'' is sometimes called the lipstick tree. Etymology and common names The name, ''Bixa orellana'', was given by Linnaeus. The botanical genus name derives from the aborig ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bixin
Bixin is an apocarotenoid found in the seeds of the achiote tree (''Bixa orellana'') from which it derives its name. It is commonly extracted from the seeds to form annatto, a natural food coloring, containing about 5% pigments of which 70-80% are bixin. Applications : center, red seeds of the achiote tree : left, Bixin is one of the colorants used in the snack Cheetos. Several thousand tons are harvested annually. Chemical properties Bixin is unstable. It isomerizes into ''trans''-bixin (β-bixin), the double-bond isomer. : Bixin is soluble in fats and alcohols but insoluble in water.

Vice-Chancellor
A chancellor is a leader of a college or university, usually either the executive or ceremonial head of the university or of a university campus within a university system. In most Commonwealth of Nations, Commonwealth and former Commonwealth nations, the chancellor is usually a ceremonial non-resident head of the university. In such institutions, the chief executive of a university is the vice-chancellor, who may carry an additional title such as ''president'' (e.g. "president & vice-chancellor"). The chancellor may serve as chairperson of the governing body; if not, this duty is often held by a chairperson who may be known as a pro-chancellor. In many countries, the administrative and educational head of the university is known as the president, principal (academia), principal or rector (academia), rector. In the United States, the head of a university is most commonly a university president. In U.S., university systems that have more than one affiliated university or campus, ...

Manchester
Manchester () is a city in Greater Manchester, England. It had a population of 552,000 in 2021. It is bordered by the Cheshire Plain to the south, the Pennines to the north and east, and the neighbouring city of Salford to the west. The two cities and the surrounding towns form one of the United Kingdom's most populous conurbations, the Greater Manchester Built-up Area, which has a population of 2.87 million. The history of Manchester began with the civilian settlement associated with the Roman fort ('' castra'') of ''Mamucium'' or ''Mancunium'', established in about AD 79 on a sandstone bluff near the confluence of the rivers Medlock and Irwell. Historically part of Lancashire, areas of Cheshire south of the River Mersey were incorporated into Manchester in the 20th century, including Wythenshawe in 1931. Throughout the Middle Ages Manchester remained a manorial township, but began to expand "at an astonishing rate" around the turn of the 19th century. Manchest ...
