Context: England is a country that is part of the United Kingdom. It shares land borders with Scotland to the north and Wales to the west. The Irish Sea lies northwest of England and the Celtic Sea lies to the southwest. England is separated from continental Europe by the North Sea to the east and the English Channel to the south. The country covers five-eighths of the island of Great Britain (which lies in the North Atlantic) in its centre and south; and includes over 100 smaller islands such as the Isles of Scilly, and the Isle of Wight., Hornby Dock was a dock located on the River Mersey, England, and part of the Port of Liverpool. It was situated in the northern dock system in Bootle. It connected to Gladstone Dock to the north and Alexandra Dock to the south and encompassed a sloping quayside. , The City and South London Railway (C&SLR) was the first deep-level underground "tube" railway in the world, and the first major railway to use electric traction. The railway was originally intended for cable-hauled trains, but owing to the bankruptcy of the cable contractor during construction, a system of electric traction using electric locomotivesan experimental technology at the timewas chosen instead., The Mersey Docks and Harbour Company (MDHC), formerly the Mersey Docks and Harbour Board (MDHB), owns and administers the dock facilities of the Port of Liverpool, on the River Mersey, England. These include the operation of the enclosed northern dock system that runs from Prince's Dock to Seaforth Dock, in the city of Liverpool and the dock facilities built around the Great Float of the Wirral Peninsula, located on the west side of the river., The Liverpool Overhead Railway (known locally as the Dockers' Umbrella) was an overhead railway in Liverpool which operated along the Liverpool Docks and opened in 1893 with lightweight electric multiple units. The railway had a number world firsts; it was the first electric elevated railway, the first to use automatic signalling & electric colour light signals, electric multiple units, and was home to one of the first passenger escalator at a railway station. It was also the second oldest electric metro in the world being preceded by the 1890 City and South London Railway. In the early 1900s electric trains ran on the electrified Lancashire and Yorkshire Railway to Southport and Aintree. Special trains to Aintree for the horse race meetings ran twice a year after regular services were withdrawn. Being a local railway it was not nationalised in 1948., Liverpool, in North West England, is a major city and metropolitan borough with an estimated population of 478,580 in 2015 within the City of Liverpool. Liverpool and its surrounding areas form the fifth largest metropolitan area in the UK, with an estimated population of over 2.24 million in 2011. The local authority is Liverpool City Council, which is the most populous local government district within the metropolitan county of Merseyside and the largest within the Liverpool City Region., The River Mersey is a river in the north west of England. Its name is derived from the Anglo-Saxon language and translates as "boundary river". The river may have been the border between the ancient kingdoms of Mercia and Northumbria and for centuries it formed part of the boundary between the historic counties of Lancashire and Cheshire., Gladstone Dock is a dock on the River Mersey, England, and part of the Port of Liverpool. It is situated in the northern dock system in Bootle. The dock is connected to Seaforth Dock to the north and what remains of Hornby Dock to the south. Part of Liverpool Freeport, Gladstone Dock is operated by the Mersey Docks and Harbour Company., The Lancashire and Yorkshire Railway (L&YR) was a major British railway company before the 1923 Grouping. It was incorporated in 1847 from an amalgamation of several existing railways. It was the third-largest railway system based in Northern England (after the Midland and North Eastern Railways)., The Port of Liverpool is the enclosed dock system that runs from Brunswick Dock in Liverpool to Seaforth Dock, Seaforth, on the east side of the River Mersey and the Birkenhead Docks between Birkenhead and Wallasey on the west side of the river. The port is being extended by the building of an in-river container terminal at Seaforth Dock, name Liverpool2. The terminal will berth two 14,000 container Post-Panamax ships. The terminal was scheduled to be opened in phases during 2016, simultaneously with the widened third locks of the Panama Canal., Seaforth Dock (also known as the Royal Seaforth Dock) is a purpose-built dock and container terminal, on the River Mersey, England, at Seaforth, to the north of Liverpool. As part of the Port of Liverpool and Liverpool Freeport, it is operated by the Mersey Docks and Harbour Company. Situated at the northern end of the dock system, it is connected to Gladstone Dock to the south, which via its lock entrance provides maritime access to Seaforth Dock from the river.

He was the best-selling recording artist from 1939 to 1943, leading one of the best known big bands. Miller's recordings include "In the Mood", "Moonlight Serenade", "Pennsylvania 6-5000", "Chattanooga Choo Choo", "A String of Pearls", "At Last", "(I've Got a Gal In) Kalamazoo", "American Patrol", "Tuxedo Junction", "Elmer's Tune", and "Little Brown Jug". While he was traveling to entertain U.S. troops in France during World War II, Miller's aircraft disappeared in bad weather over the English Channel., A big band is a type of musical ensemble associated with playing jazz music and which became popular during the Swing Era from the early 1930s until the late 1940s. Big Bands evolved with the times and continue to today. A big band typically consists of approximately 12 to 25 musicians and contains saxophones, trumpets, trombones, and a rhythm section. The terms jazz band, jazz ensemble, stage band, jazz orchestra, and dance band are also used to refer to this type of ensemble. This does not, however, mean that each one of these names is technically correct for naming a "big band" specifically., Jazz is a music genre that originated amongst African Americans in New Orleans, United States, in the late 19th and early 20th centuries. Since the 1920s jazz age, jazz has become recognized as a major form of musical expression. It emerged in the form of independent traditional and popular musical styles, all linked by the common bonds of African American and European American musical parentage with a performance orientation. Jazz is characterized by swing and blue notes, call and response vocals, polyrhythms and improvisation. Jazz has roots in West African cultural and musical expression, and in African-American music traditions including blues and ragtime, as well as European military band music. Although the foundation of jazz is deeply rooted within the Black experience of the United States, different cultures have contributed their own experience and styles to the art form as well. Intellectuals around the world have hailed jazz as "one of America's original art forms"., The clarinet is a musical-instrument family belonging to the group known as the woodwind instruments. It has a single-reed mouthpiece, a straight cylindrical tube with an almost cylindrical bore, and a flared bell. A person who plays a clarinet is called a "clarinetist" (sometimes spelled "clarinettist")., Ben Pollack (June 22, 1903  June 7, 1971) was an American drummer and bandleader from the mid-1920s through the swing era. His eye for talent led him to employ musicians such as Benny Goodman, Jack Teagarden, Glenn Miller, Jimmy McPartland, and Harry James. This ability earned him the nickname the "Father of Swing"., Morey Feld ( August 15 , 1915 -- March 28 , 1971 ) was an American jazz drummer born in Cleveland , Ohio , perhaps best known for his work with the bands of Ben Pollack ( 1936 ) , Benny Goodman ( 1943 -- 1945 ) , Eddie Condon ( 1946 ) , Bobby Hackett and Billy Butterfield . In 1960 Feld moved to Denver , Colorado and worked with Peanuts Hucko 's quintet . Feld died at age 55 while attempting to fight a fire at his Denver home ., A guitarist (or a guitar player) is a person who plays the guitar. Guitarists may play a variety of guitar family instruments such as classical guitars, acoustic guitars, electric guitars, and bass guitars. Some guitarists accompany themselves on the guitar by singing or playing the harmonica., John Herbert "Jackie" Gleason (February 26, 1916June 24, 1987) was an American comedian, actor, and musician who developed a style and characters in his career from growing up in Brooklyn, New York. He was known for his brash visual and verbal comedy style, exemplified by his character Ralph Kramden in the television series "The Honeymooners". By filming the episodes with Electronicams, Gleason later could release the series in syndication, building its popularity over the years with new audiences. He also developed "The Jackie Gleason Show," which maintained high ratings from the mid-1950s until its cancellation in 1970. After having originated in Hollywood, filming of the show moved to Miami, Florida, in 1964 after Gleason himself took up permanent residence there., Robert Leo "Bobby" Hackett (January 31, 1915  June 7, 1976) was an American jazz musician who played trumpet, cornet and guitar with the bands of Glenn Miller and Benny Goodman in the late 1930s and early 1940s. Hackett is probably best known for being the featured soloist on some of the "Jackie Gleason" mood music albums during the 1950s., Weldon Leo "Jack" Teagarden (August 20, 1905  January 15, 1964), was a jazz trombonist and singer., Benjamin David "Benny" Goodman (May 30, 1909  June 13, 1986) was an American jazz and swing musician, clarinetist and bandleader, known as the "King of Swing"., A bandleader is the leader of a music group such as a rock or pop group or jazz quartet. The term is most commonly, though not exclusively, used with a group that plays popular music as a small combo or a big band, such as one which plays jazz, blues, rhythm and blues or rock and roll music. Most bandleaders are also performers with their own band, either as singers or as instrumentalists, playing an instrument such as electric guitar, piano, or other instruments., Albert Edwin Condon (November 16, 1905  August 4, 1973), better known as Eddie Condon, was an American jazz banjoist, guitarist, and bandleader.

Context: Ipomoea tricolor (grannyvine or morning glory) is a species of flowering plant in the family Convolvulaceae, native to the New World tropics, and widely cultivated and naturalised elsewhere. It is an herbaceous annual or perennial twining liana growing to tall. The leaves are spirally arranged, 37 cm long with a 1.56 cm long petiole. The flowers are trumpet-shaped, in diameter, most commonly blue with a white to golden yellow centre., An amide (or or ), also known as an acid amide, is a compound with the functional group RE(O)NR (R and R refer to H or organic groups). Most common are carboxamides (organic amides) ("n" = 1, E = C, "x" = 1), but many other important types of amides are known, including phosphoramides ("n" = 2, E = P, "x" = 1 and many related formulas) and sulfonamides (E = S, "x" = 2). The term amide refers both to "classes of compounds" and to the "functional group" (RE(O)NR) within those compounds., Chlorine is a chemical element with symbol Cl and atomic number 17. The second-lightest of the halogens, it appears between fluorine and bromine in the periodic table and its properties are mostly intermediate between them. Chlorine is a yellow-green gas at room temperature. It is an extremely reactive element and a strong oxidising agent: among the elements, it has the highest electron affinity and the third-highest electronegativity, behind only oxygen and fluorine., Psilocybin is a naturally occurring psychedelic compound produced by more than 200 species of mushrooms, collectively known as psilocybin mushrooms. The most potent are members of the genus "Psilocybe", such as "P. azurescens", "P. semilanceata", and "P. cyanescens", but psilocybin has also been isolated from about a dozen other genera. As a prodrug, psilocybin is quickly converted by the body to psilocin, which has mind-altering effects similar, in some aspects, to those of LSD, mescaline, and DMT. In general, the effects include euphoria, visual and mental hallucinations, changes in perception, a distorted sense of time, and spiritual experiences, and can include possible adverse reactions such as nausea and panic attacks., Lysergic acid, also known as -lysergic acid and (+)-lysergic acid, is a precursor for a wide range of ergoline alkaloids that are produced by the ergot fungus and found in the seeds of "Turbina corymbosa" (ololiuhqui), "Argyreia nervosa" (Hawaiian Baby Woodrose), and "Ipomoea tricolor" (morning glories, tlitliltzin). Amides of lysergic acid, lysergamides, are widely used as pharmaceuticals and as psychedelic drugs (LSD). Lysergic acid received its name as it was a product of the lysis of various ergot alkaloids., Ergoline is a chemical compound whose structural skeleton is contained in a diverse range of alkaloids. Ergoline derivatives are used clinically for the purpose of vasoconstriction (5-HT receptor agonistsergotamine) and in the treatment and alleviation of migraines (used with caffeine) and Parkinson's disease. Some ergoline alkaloids found in ergot fungi are implicated in the condition ergotism, which causes convulsive and gangrenous symptoms. Others are psychedelic substances, including LSD and some alkaloids in "Argyreia nervosa", "Ipomoea tricolor" and related species., Lysergic acid diethylamide (LSD), also known as acid, is a psychedelic drug known for its psychological effects. This may include altered awareness of the surroundings, perceptions, and feelings as well as sensations and images that seem real though they are not. It is used mainly as a recreational drug and for spiritual reasons. LSD is typically either swallowed or held under the tongue. It is often sold on blotter paper, a sugar cube, or gelatin. It can also be injected.
LSD is not addictive. However, adverse psychiatric reactions such as anxiety, paranoia, and delusions are possible. LSD is in the ergoline family. LSD is sensitive to oxygen, ultraviolet light, and chlorine, though it may last for years if it is stored away from light and moisture at low temperature. In pure form it is odorless and clear or white in color. As little as 2030 micrograms can produce an effect.
LSD was first made by Albert Hofmann in Switzerland in 1938 from ergotamine, a chemical from the fungus ergot. The laboratory name for the compound was the acronym for the German "Lyserg-säure-diäthylamid", followed by a sequential number: LSD-25. Hofmann discovered its psychedelic properties in 1943. LSD was introduced as a commercial medication under the trade-name Delysid for various psychiatric uses in 1947. In the 1950s, officials at the U.S. Central Intelligence Agency (CIA) thought the drug might be useful for mind control and chemical warfare and tested the drug on young servicemen and students, and others without their knowledge. The subsequent recreational use by youth culture in the Western world as part of 1960s counterculture resulted in its prohibition., Mescaline, or 3,4,5-trimethoxyphenethylamine, is a naturally occurring psychedelic alkaloid of the phenethylamine class, known for its hallucinogenic effects comparable to those of LSD and psilocybin., Sir Timothy John Berners-Lee (born 8 June 1955), also known as TimBL, is an English computer scientist, best known as the inventor of the World Wide Web. He made a proposal for an information management system in March 1989, and he implemented the first successful communication between a Hypertext Transfer Protocol (HTTP) client and server via the Internet sometime around mid-November of that same year., Albert Hofmann ( January 11 , 1906 -- April 29 , 2008 ) was a Swiss scientist known best for being the first person to synthesize , ingest , and learn of the psychedelic effects of lysergic acid diethylamide ( LSD ) . Hofmann was also the first person to isolate , synthesize , and name the principal psychedelic mushroom compounds psilocybin and psilocin . He authored more than 100 scientific articles and numerous books , including LSD : Mein Sorgenkind ( LSD : My Problem Child ) . In 2007 , he shared first place , alongside Tim Berners - Lee , in a list of the 100 greatest living geniuses , published by The Telegraph newspaper ., Psilocin (also known as 4-HO-DMT, psilocine, psilocyn, or psilotsin) is a substituted tryptamine alkaloid and a serotonergic psychedelic substance. It is present in most psychedelic mushrooms together with its phosphorylated counterpart psilocybin. Psilocin is a Schedule I drug under the Convention on Psychotropic Substances. The mind-altering effects of psilocin are highly variable and subjective and resemble those of LSD and DMT., Albert Hofmann (11 January 1906  29 April 2008) was a Swiss scientist known best for being the first person to synthesize, ingest, and learn of the psychedelic effects of lysergic acid diethylamide (LSD). Hofmann was also the first person to isolate, synthesize, and name the principal psychedelic mushroom compounds psilocybin and psilocin. He authored more than 100 scientific articles and numerous books, including "LSD: Mein Sorgenkind" ("LSD: My Problem Child"). In 2007, he shared first place, alongside Tim Berners-Lee, in a list of the 100 greatest living geniuses, published by "The Telegraph" newspaper., Panic attacks are sudden periods of intense fear that may include palpitations, sweating, shaking, shortness of breath, numbness, or a feeling that something bad is going to happen. The maximum degree of symptoms occurs within minutes. Typically they last for about 30 minutes but the duration can vary from seconds to hours. There may be a fear of losing control or chest pain. Panic attacks themselves are not dangerous.
Panic attacks can occur due to number of disorders including panic disorder, social anxiety disorder, post traumatic stress disorder, drug use, depression, and medical problems. They can either be triggered or occur unexpectedly. Risk factors include smoking and psychological stress. Diagnosis should involve ruling out other conditions that can produce similar symptoms including hyperthyroidism, hyperparathyroidism, heart disease, lung disease, and drug use.
Treatment of panic attacks should be directed at the underlying cause. In those with frequent attacks, counselling or medications may be used. Breathing training and muscle relaxation techniques may also help. Those affected are at a higher risk of suicide.
In Europe about 3% of the population has a panic attack in a given year while in the United States they affect about 11%. They are more common in females than males. They often begin during puberty or early adulthood. Children and older people are less commonly affected., A prodrug is a medication or compound that, after administration, is metabolized (i.e., converted within the body) into a pharmacologically active drug. Inactive prodrugs are pharmacologically inactive medications that are metabolized into an active form within the body. Instead of administering a drug directly, a corresponding prodrug might be used instead to improve how a medicine is absorbed, distributed, metabolized, and excreted (ADME). Prodrugs are often designed to improve bioavailability when a drug itself is poorly absorbed from the gastrointestinal tract. A prodrug may be used to improve how selectively the drug interacts with cells or processes that are not its intended target. This reduces adverse or unintended effects of a drug, especially important in treatments like chemotherapy, which can have severe unintended and undesirable side effects.
History.
Many herbal extracts historically used in medicine contain glycosides (sugar derivatives) of the active agent, which are hydrolyzed in the intestines to release the active and more bioavailable aglycone. For example, salicin is a -D-glucopyranoside that is cleaved by esterases to release salicylic acid. Aspirin, acetylsalicylic acid, first made by Felix Hoffmann at Bayer in 1897, is a synthetic prodrug of salicylic acid. However, in other cases, such as codeine and morphine, the administered drug is enzymatically activated to form sugar derivatives (morphine-glucuronides) that are more active than the parent compound., The Convention on Psychotropic Substances of 1971 is a United Nations treaty designed to control psychoactive drugs such as amphetamine-type stimulants, barbiturates, benzodiazepines, and psychedelics signed in Vienna, Austria on 21 February 1971. The Single Convention on Narcotic Drugs of 1961 could not ban the many newly discovered psychotropics, since its scope was limited to drugs with cannabis, coca, and opium-like effects., The World Wide Web (abbreviated WWW or the Web) is an information space where documents and other web resources are identified by Uniform Resource Locators (URLs), interlinked by hypertext links, and can be accessed via the Internet. English scientist Tim Berners-Lee invented the World Wide Web in 1989. He wrote the first web browser computer program in 1990 while employed at CERN in Switzerland., Subject: albert hofmann, Relation: date_of_birth, Options: (A) 1 (B) 11 (C) 11 january 1906 (D) 17 (E) 1897 (F) 1906 (G) 1938 (H) 1943 (I) 1971 (J) 1989 (K) 1990 (L) 2 (M) 20 (N) 200 (O) 2008 (P) 25 (Q) 3 (R) 30 (S) 4 (T) 5 (U) 6 (V) 8 (W) 8 june 1955 (X) january 1906 (Y) june 1955
