John Lionel Simonsen
Sir John Lionel Simonsen (22 July 1884, in Levenshulme, Manchester – 20 February 1957, in London) was an English organic chemist who worked in India. He contributed to organic syntheses and studied the chemistry of many plant extracts. He was knighted in 1949. Life and work Simonsen was born in Levenshulme, Manchester where their parents had settled from Denmark (his father Lionel Michael Simonsen was a merchant while his mother Sophie had several relatives in Copenhagen University), he went to a private school in Rusholme and then attended the Manchester Grammar School where he was influenced by the chemistry teacher Francis Jones. He took an interest in science after spending summers in Copenhagen where an uncle, Valdemar Henriques, taught physiology at the Landbrughy Skole. He then went to the University of Manchester, where he obtained his bachelor's degree with top grades in 1904, and a Ph.D. in 1909 as a student of William Henry Perkin Jr. In 1907 he became an assis ...

Agricultural Research Council
The Agricultural and Food Research Council (AFRC) was a British Research Council responsible for funding and managing scientific and technological developments in farming and horticulture. History The AFRC was formed in 1983 from its predecessor, the Agricultural Research Council (ARC). It was replaced by the Biotechnology and Biological Sciences Research Council (BBSRC) as a result of government reorganisation in 1994. At that time Sir William Henderson who was secretary to the AFRC claimed that "agriculture was a success story" hence the AFRC could be closed and a new vision for research was envisaged in the creation of the BBSRC. With this shift in emphasis, there also followed the closure of several educational and research organisations as for example the internationally renowned Wye College bio sciences -> social sciences -> business school Pictures of OLT, Old Hall,Cloister, Parlour --> The College of St Gregory and St Martin at Wye, commonly known as Wye College, ...

Davy Medal
The Davy Medal is awarded by the Royal Society of London "for an outstandingly important recent discovery in any branch of chemistry". Named after Humphry Davy, the medal is awarded with a monetary gift, initially of £1000 (currently £2000). History The medal was first awarded in 1877 to Robert Wilhelm Bunsen and Gustav Robert Kirchhoff "for their researches & discoveries in spectrum analysis", and has since been awarded 140 times. The medal is awarded annually and, unlike other Royal Society medals (such as the Hughes), has been awarded without interruption since its inception. The medal has been awarded to multiple individuals in the same year: in 1882, for example, it was awarded to Dmitri Mendeleev and Julius Lothar Meyer "for their discovery of the periodic relations of the atomic weights"; in 1883 to Marcellin Berthelot and Julius Thomsen "for their researches in thermo-chemistry"; in 1893 to Jacobus Henricus van 't Hoff and Joseph Achille Le Bel "In recognition of thei ...

British Guiana
British Guiana was a British colony, part of the mainland British West Indies, which resides on the northern coast of South America. Since 1966 it has been known as the independent nation of Guyana. The first European to encounter Guiana was Sir Walter Raleigh, an English explorer. The Dutch were the first Europeans to settle there, starting in the early 17th century, when they founded the colonies of Essequibo and Berbice, adding Demerara in the mid-18th century. In 1796, Great Britain took over these three colonies during hostilities with the French, who had occupied the Netherlands. Britain returned control to the Batavian Republic in 1802 but captured the colonies a year later during the Napoleonic Wars. The colonies were officially ceded to the United Kingdom in 1815 and consolidated into a single colony in 1831. The colony's capital was at Georgetown (known as Stabroek prior to 1812). The economy has become more diversified since the late 19th century but has relied on r ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mosquito
Mosquitoes (or mosquitos) are members of a group of almost 3,600 species of small flies within the family Culicidae (from the Latin ''culex'' meaning " gnat"). The word "mosquito" (formed by ''mosca'' and diminutive ''-ito'') is Spanish for "little fly". Mosquitoes have a slender segmented body, one pair of wings, one pair of halteres, three pairs of long hair-like legs, and elongated mouthparts. The mosquito life cycle consists of egg, larva, pupa, and adult stages. Eggs are laid on the water surface; they hatch into motile larvae that feed on aquatic algae and organic material. These larvae are important food sources for many freshwater animals, such as dragonfly nymphs, many fish, and some birds such as ducks. The adult females of most species have tube-like mouthparts (called a proboscis) that can pierce the skin of a host and feed on blood, which contains protein and iron needed to produce eggs. Thousands of mosquito species feed on the blood of various hosts ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Caribbean
The Caribbean (, ) ( es, El Caribe; french: la Caraïbe; ht, Karayib; nl, De Caraïben) is a region of the Americas that consists of the Caribbean Sea, its islands (some surrounded by the Caribbean Sea and some bordering both the Caribbean Sea and the North Atlantic Ocean) and the surrounding coasts. The region is southeast of the Gulf of Mexico and the North American mainland, east of Central America, and north of South America. Situated largely on the Caribbean Plate, the region has more than 700 islands, islets, reefs and cays (see the list of Caribbean islands). Island arcs delineate the eastern and northern edges of the Caribbean Sea: The Greater Antilles and the Lucayan Archipelago on the north and the Lesser Antilles and the on the south and east (which includes the Leeward Antilles). They form the West Indies with the nearby Lucayan Archipelago (the Bahamas and Turks and Caicos Islands), which are considered to be part of the Caribbean despite not bordering the Caribbe ...

Turpentine
Turpentine (which is also called spirit of turpentine, oil of turpentine, terebenthene, terebinthine and (colloquially) turps) is a fluid obtained by the distillation of resin harvested from living trees, mainly pines. Mainly used as a specialized solvent, it is also a source of material for organic syntheses. Turpentine is composed of terpenes, primarily the monoterpenes alpha- and beta-pinene, with lesser amounts of carene, camphene, dipentene, and terpinolene.Kent, James A. ''Riegel's Handbook of Industrial Chemistry'' (Eighth Edition) Van Nostrand Reinhold Company (1983) p.569 Mineral turpentine or other petroleum distillates are used to replace turpentine – although the constituent chemicals are very different. Etymology The word ''turpentine'' derives (via French and Latin), from the Greek word τερεβινθίνη ''terebinthine'', in turn the feminine form (to conform to the feminine gender of the Greek word, which means "resin") of an adjective (τερεβί ...
