Question: What was the age of the oldest member (besides Stephanie) of the group representing Armenia in the Eurovision Song Contest 2015? Passage 1:Chemokine receptors are G protein-coupled receptors containing 7 transmembrane domains that are found predominantly on the surface of leukocytes, making it one of the rhodopsin-like receptors. Approximately 19 different chemokine receptors have been characterized to date, which share many common structural features; they are composed of about 350 amino acids that are divided into a short and acidic N-terminal end, seven helical transmembrane domains with three intracellular and three extracellular hydrophilic loops, and an intracellular C-terminus containing serine and threonine residues that act as phosphorylation sites during receptor regulation. The first two extracellular loops of chemokine receptors are linked together by disulfide bonding between two conserved cysteine residues. The N-terminal end of a chemokine receptor binds to chemokine(s) and is important for ligand specificity. G-proteins couple to the C-terminal end, which is important for receptor signaling following ligand binding. Although chemokine receptors share high amino acid identity in their primary sequences, they typically bind a limited number of ligands. Chemokine receptors are redundant in their function as more than one chemokine is able to bind to a single receptor.
Passage 2:A return to the Formula Three Euroseries beckoned for van Dam, with a 2009 campaign for Kolles & Heinz Union, the new team set up by Colin Kolles and Werner Heinz. However, the partnership was not to last, as after the rounds at Lausitz, van Dam parted company with the team. In four races, his best finish was eighteenth during the season-opening race at Hockenheim. Van Dam drove in the 24-hour endurance races at the Nurburgring and at Spa, before agreeing to drive the car of PSV Eindhoven in the Superleague Formula series. He replaced Dominick Muermans in the car, with the team lying eighteenth in the overall standings. However, he returned to the Euroseries, for the Barcelona rounds, rejoining his former team SG Formula.
Passage 3:In February 2015 she was announced as a member of the music group Genealogy (made up of singers from Armenia and the Armenian diaspora) that represented Armenia in the Eurovision Song Contest 2015. Stephanie Topalian represents the Asian continent in the formation whereas the Ethiopian Vahe Tilbian represents Africa, the American Tamar Kaprelian the American continent, the French Essai Altounian the European continent and the Australian Mary-Jean O'Doherty Basmadjian Oceania and Inga Arshakyan Armenia. The super group sang "Face the Shadow", the Armenian entry to the 2015 Eurovision Song Contest in Vienna, Austria. She became an Armenian citizen along with the other foreign members of Genealogy on 28 April 2015 after being given Armenian passports by President Serzh Sargsyan.

Question: What other dongs had won the Ivor Novello Award before the Beatles "Something" won it? Passage 1:From the mid-1970s, DJs in early discotheques were performing similar tricks with disco songs (using loops and tape edits) to get dancers on the floor and keep them there. One noteworthy figure was Tom Moulton who invented the dance remix as we now know it. Though not a DJ (a popular misconception), Moulton had begun his career by making a homemade mix tape for a Fire Island dance club in the late 1960s. His tapes eventually became popular and he came to the attention of the music industry in New York City. At first Moulton was simply called upon to improve the aesthetics of dance-oriented recordings before release ("I didn't do the remix, I did the mix"Tom Moulton). Eventually, he moved from being a "fix it" man on pop records to specializing in remixes for the dance floor. Along the way, he invented the breakdown section and the 12-inch single vinyl format. Walter Gibbons provided the dance version of the first commercial 12-inch single ("Ten Percent", by Double Exposure). Contrary to popular belief, Gibbons did not mix the record. In fact his version was a re-edit of the original mix. Moulton, Gibbons and their contemporaries (Jim Burgess, Tee Scott, and later Larry Levan and Shep Pettibone) at Salsoul Records proved to be the most influential group of remixers for the disco era. The Salsoul catalog is seen (especially in the UK and Europe) as being the "canon" for the disco mixer's art form. Pettibone is among a very small number of remixers whose work successfully transitioned from the disco to the House era. (He is certainly the most high-profile remixer to do so.) His contemporaries included Arthur Baker and Francois Kevorkian.
Passage 2:"Something" received the Ivor Novello Award for the "Best Song Musically and Lyrically" of 1969. Harrison subsequently performed the song at his Concert for Bangladesh shows in 1971 and throughout the two tours he made as a solo artist. Up to the late 1970s, it had been covered by over 150 artists, making it the second-most covered Beatles composition after "Yesterday". Shirley Bassey had a top-five UK hit with her 1970 recording, while Frank Sinatra regularly performed the song. Other artists who have covered "Something" include Elvis Presley, Ray Charles, Peggy Lee, James Brown, Tony Bennett, Andy Williams, Smokey Robinson and Ike & Tina Turner. In 1999, Broadcast Music Incorporated named "Something" as the 17th-most performed song of the twentieth century, with 5 million performances. In 2004, it was ranked at number 278 on Rolling Stones list of "The 500 Greatest Songs of All Time", while two years later, Mojo placed it at number 7 in the magazine's list of the Beatles' best songs. A year after Harrison's death in November 2001, McCartney and Eric Clapton performed it at the Concert for George tribute at London's Royal Albert Hall.
Passage 3:The USS Essex had been constructed in 1856. She was a 1000-ton river gunboat, converted from her original role as a timberclad ferry named New Era. She was armed with one 32-pounder cannon, three Dahlgren smooth bores, one Dahlgren smoothbore and a 12-pounder howitzer. The USS St Louis was a City class ironclad built in 1861 at Carondelet, Missouri. She was armed with three 8-inch smoothbores, four 42-pounder rifles, six 32-pounder rifles and one 12-pounder rifle at the time of her service at Lucas Bend. Both ships were sent to Cairo, Illinois, early in the Civil War as part of troop transports moving the army into Tennessee. Illinois, a Union state which contributed 250,000 men to the Union Army, a figure surpassed by only New York, Pennsylvania, and Ohio, was a key theater. Cairo, at the confluence between the Mississippi and Ohio rivers, was a key supply point and headquarters for Flag Officer Andrew Hull Foote and General Ulysses S. Grant. It was defended by Fort Defiance. The complex river network provided routes for the Union gunboats into the heart of the Confederate forces; however the water levels particularly in the Tennessee River were often not sufficient for gunboats to pass.

Question: How many months after the Piccadily line was created did it join with the London Underground's District line? Passage 1:The original catalyst for development was the ill-fated vanity project by Lord Kensington (died 1852) which consisted of the two-mile conversion of the insanitary Counter's Creek into the Kensington Canal (1826 onwards), followed by its eventual replacement first by "Mr Punch's railway", opened in 1844 and next, by the Metropolitan District Railway in 186569, which eventually became London Underground's District Line and was joined after 1907 by the Piccadilly line. Meanwhile, the congestion apparent in London and Middlesex for burials at the start of the century was causing public concern not least on health grounds. In 1837 a decision was made to lay out a new burial ground on the edge of Earl's Court in an outlying area of Brompton. The moving spirit behind the project was the engineer, Stephen Geary. It was necessary to form a company in order to get parliamentary permission to raise capital for the proposal. Securing the land some 40 acres from local landowner, Lord Kensington and the Equitable Gas Light Company, as well as raising the money proved an extended challenge. After two years the cemetery was duly established by Act of Parliament and laid out in 1839, it opened in 1840, originally as the West of London and Westminster Cemetery. It was consecrated by Charles James Blomfield, Bishop of London in June 1840, and is now one of Britain's oldest and most distinguished garden cemeteries, served by the adjacent West Brompton station.
Passage 2:Bonko first sought political office in the 1995 municipal election, when he was elected to the Board of Edmonton Public Schools as trustee for Ward A. He was re-elected in the 1998 and 2001 elections. He did not seek re-election at the conclusion of his third term. Instead, he ran for the Legislative Assembly of Alberta in Edmonton Decore in the 2004 provincial election as a Liberal. He won 44.63% of the vote and defeated his opponents, who included former MLA Walter Szwender who was running for the Progressive Conservatives and Gary Masyk, an incumbent MLA whose riding had been abolished and who had crossed the floor to become the Alberta Alliance's first MLA after being elected as PC. He did not sponsor any bills during his time in the legislature, and was defeated by Progressive Conservative candidate Janice Sarich in the 2008 election.
Passage 3:With the outbreak of the Civil War, Weed was promoted captain of the newly formed Battery I, 5th U.S. Artillery in May 1861. He remained at Camp Curtin in Harrisburg, Pennsylvania, training his crews until the spring of 1862, when they served in the Peninsula Campaign and at Second Bull Run. He commanded his battery during the fierce artillery duel at Antietam. Promoted to command of all the artillery of the V Corps, his guns were in action at the Battle of Fredericksburg. From December 1862 through January 1863, he was stationed at Falmouth, Virginia. After a short leave of absence, he took part in the Battle of Chancellorsville, commanding the artillery of the 2nd Division, V Corps. On June 6, 1863, Weed left the regular army artillery to accept a commission as a brigadier general in the volunteer army. He was assigned command of 3rd Brigade in the 2nd Division, V Corps.
