Alderney
Alderney (; french: Aurigny ; Auregnais: ) is the northernmost of the inhabited Channel Islands. It is part of the Bailiwick of Guernsey, a British Crown dependency. It is long and wide. The island's area is , making it the third-largest island of the Channel Islands, and the second largest in the Bailiwick. It is around to the west of the La Hague on the Cotentin Peninsula, Normandy, in France, to the northeast of Guernsey and from the south coast of Great Britain. It is the closest of the Channel Islands both to France and to the United Kingdom. It is separated from Cap de la Hague by the dangerous Alderney Race (french: Raz Blanchard). As of March 2018, the island had a population of 2,019; natives are traditionally nicknamed after the cows, or else after the many rabbits seen in the island. Formally, they are known as ''Ridunians'', from the Latin . The only parish of Alderney is the parish of St Anne, which covers the whole island. The main town, St Anne, h ...

Aldehyde
In organic chemistry, an aldehyde () is an organic compound containing a functional group with the structure . The functional group itself (without the "R" side chain) can be referred to as an aldehyde but can also be classified as a formyl group. Aldehydes are common and play important roles in the technology and biological spheres. Structure and bonding Aldehydes feature a carbon center that is connected by a double bond to oxygen and a single bond to hydrogen and single bond to a third substituent, which is carbon or, in the case of formaldehyde, hydrogen. The central carbon is often described as being sp2- hybridized. The aldehyde group is somewhat polar. The C=O bond length is about 120-122 picometers. Physical properties and characterization Aldehydes have properties that are diverse and that depend on the remainder of the molecule. Smaller aldehydes are more soluble in water, formaldehyde and acetaldehyde completely so. The volatile aldehydes have pungent odors. Al ...

Alderman
An alderman is a member of a Municipal government, municipal assembly or council in many Jurisdiction, jurisdictions founded upon English law. The term may be titular, denoting a high-ranking member of a borough or county council, a council member chosen by the elected members themselves rather than by Direct election, popular vote, or a council member elected by voters. Etymology The title is derived from the Old English title of ''ealdorman'', literally meaning "elder man", and was used by the chief nobles presiding over shires. Similar titles exist in some Germanic countries, such as the Sweden, Swedish language ', the Danish language, Danish, Low German, Low German language ', and West Frisia, West Frisian language ', the Netherlands, Dutch language ', the (non-Germanic) Finland, Finnish language ' (a borrowing from the Germanic Swedes next door), and the German language, High German ', which all mean "elder man" or "wise man". Usage by country Australia Many local government ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Alderson Station
Alderson station is an Amtrak station in Alderson, West Virginia, served by the ''Cardinal''. It is located at 1 C&O Plaza, and functions as a request stop. The station is a contributing property within the Alderson Historic District, which has been listed on the National Register of Historic Places since November 12, 1993. The wood frame depot, originally built by the Chesapeake and Ohio Railway (C&O) in 1896, is typical of a standard station built on the C&O system between 1890 and 1914. It features board and batten walls, decorative brackets, fancy stick work on the gable ends and deep eaves. The railroad enlarged the structure in 1924. Amtrak began serving the community on April 29, 1979. Between December 4, 2001, and the second half of 2004, service to the station was suspended, partially due to painting that changed the station from white to orange. It was Amtrak's third least-busy station for fiscal year A fiscal year (or financial year, or sometimes budget year) is use ...

Aldehyde Dehydrogenase
Aldehyde dehydrogenases () are a group of enzymes that catalyse the oxidation of aldehydes. They convert aldehydes (R–C(=O)) to carboxylic acids (R–C(=O)). The oxygen comes from a water molecule. To date, nineteen ALDH genes have been identified within the human genome. These genes participate in a wide variety of biological processes including the detoxification of exogenously and endogenously generated aldehydes. Function Aldehyde dehydrogenase is a polymorphic enzyme responsible for the oxidation of aldehydes to carboxylic acids, which leave the liver and are metabolized by the body’s muscle and heart. There are three different classes of these enzymes in mammals: class 1 (low ''K''m, cytosolic), class 2 (low ''K''m, mitochondrial), and class 3 (high ''K''m, such as those expressed in tumors, stomach, and cornea). In all three classes, constitutive and inducible forms exist. ALDH1 and ALDH2 are the most important enzymes for aldehyde oxidation, and both a ...

Alderley Edge Railway Station
Alderley Edge railway station serves the large village of Alderley Edge in Cheshire, England. The station is 13¾ miles (22 km) south of Manchester Piccadilly on the Crewe to Manchester Line. History Opened by the Manchester and Birmingham Railway, then absorbed by the London and North Western Railway, it became part of the London, Midland and Scottish Railway during the grouping of 1923. The line then passed on to the London Midland Region of British Railways on nationalisation in 1948. When sectorisation was introduced, the station was served by Regional Railways on behalf of the Greater Manchester Passenger Transport Executive until the privatisation of British Railways. The line was electrified in 1960 (as the first stage of the West Coast Main Line electrification project) - since then, the station has acted as a terminus for some local services from the Manchester direction. Both platforms are bi-directionally signalled to facilitate this and there are t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Aldolase
Fructose-bisphosphate aldolase (), often just aldolase, is an enzyme catalyzing a reversible reaction that splits the aldol, fructose 1,6-bisphosphate, into the triose phosphates dihydroxyacetone phosphate (DHAP) and glyceraldehyde 3-phosphate (G3P). Aldolase can also produce DHAP from other (3S,4R)-ketose 1-phosphates such as fructose 1-phosphate and sedoheptulose 1,7-bisphosphate. Gluconeogenesis and the Calvin cycle, which are anabolic pathways, use the reverse reaction. Glycolysis, a catabolic pathway, uses the forward reaction. Aldolase is divided into two classes by mechanism. The word aldolase also refers, more generally, to an enzyme that performs an aldol reaction (creating an aldol) or its reverse (cleaving an aldol), such as Sialic acid aldolase, which forms sialic acid. See the list of aldolases. Mechanism and structure Class I proteins form a protonated Schiff base intermediate linking a highly conserved active site lysine with the DHAP carbonyl carbon. Addit ...

ALD-52
ALD-52, also known as 1-acetyl-LSD, is a chemical analogue of lysergic acid diethylamide (LSD). It was originally discovered by Albert Hofmann in 1957 but was not widely studied until the rise in popularity of psychedelics in the 1960s. Effects In Entry 26 of his compendium ''TiHKAL'', which discussed LSD, chemist Alexander Shulgin touched briefly on the subject of ALD-52. His comments there are vague, second-hand accounts saying doses in the 50–175 µg range have resulted in various conclusions. One account found that there was less visual distortion than with LSD and it seemed to produce less anxiety and tenseness and that it was somewhat less potent. Another informant claimed it was more effective in increasing blood pressure. Yet another informant could not tell them apart. Safety In ''The Hallucinogens'' by Hoffer and Osmond (1967), ALD-52 is listed as having a lower (approximately 1/5) ''intravenous'' toxicity (in rabbits), a lower (approximately 1/8) pyretogen ...
