Question: Where was McMahon's post-doctoral mentor from? Passage 1:Ain't She Sweet was an American album featuring four tracks recorded in Hamburg in 1961 by The Beatles featuring Tony Sheridan (except for the title song with vocal by John Lennon) and cover versions of Beatles and British Invasion-era songs recorded by the Swallows. As Atlantic Records only had rights to four Sheridan/Beatle recordings recorded by Polydor Records, they filled the rest of the album with Beatle and British Invasion cover songs. When this material was released by Atco Records, there were mono (catalogue number 33-169) and stereo (SD 33-169) editions. Atco also added additional drum overdubs to the four Sheridan cuts on top of the original drum tracks. American drummer Bernard Purdie claims to have performed overdubs of unspecified Beatles records, which would most likely have been for Ain't She Sweet, but this has never been officially confirmed.
Passage 2:McMahon contributed to the understanding of retinal neurophysiology alongside his post-doctoral mentor, John E. Dowling. His early research focused on ion channels that mediate transmission at electrical and glutamatergic synapses and the modulatory effects of dopamine and nitric oxide on retinal synapse networks. Through studies with zebrafish he discovered that the neurotransmitter dopamine decreases the electrical coupling within horizontal cells. Further research showed that it was the increase of cAMP within the cell resulting from dopamine binding to AMPA receptor that led to this decrease in coupling. McMahon and his colleagues also demonstrated that exogenous nitric oxide and zinc can modulate AMPA receptor mediated synaptic transmission at gap junctions in hybrid bass retinal neurons.
Passage 3:The river starts at Ralph Bice Lake (formerly Butt Lake) in northern Algonquin Provincial Park in the geographic township of Butt in the Unorganized South Part of Nipissing District. It flows south to Daisy Lake then east to Big Trout Lake. The river heads north out the lake over Big Trout Lake Dam, takes in the left tributary Tim River, flows over the Portal Rapids, Cedar Rapids, Snowshoe Rapids, Catfish Rapids, and Stacks Rapids to reach Cedar Lake, the location of the community of Brent, where it takes in the left tributary Nipissing River. The river exits the lake over a dam, heads through the Devil's Chute, reaches Radiant Lake, where it takes in the left tributary North River and right tributary Little Madawaska River, and passes through the Squirrel Rapids, Big Sawyer Rapids, Battery Rapids Cascade Rapids and White Horse Rapids, and takes in the right tributary Crow River. The river then continues through a series of rapids including the Devil's Cellar Rapids, passes the Algonquin Radio Observatory, and reaches Lake Travers. The Petawawa River enters a canyon and passes through numerous rapids including the Big Thompson Rapids, Little Thompson Rapids, Grillade Rapids, Crooked Chute, Rollway Rapids, The Natch, Schooner Rapids, Five Mile Rapids to arrive at Whitson Lake adjacent to the Petawawa Hills. It leaves Algonquin Provincial Park and enters the municipality of Laurentian Hills in Renfrew County, continues southeast past CFB Petawawa, passes through the Crooked Rapids, Race Horse Rapids, White Horse Rapids and Halfmile Rapids, and reaches Lac du Bois Dur, where it takes in the right tributary Barron River. The river enters the town of Petawawa, heads under Ontario Highway 17, through the Big Eddy Rapids, under the Canadian Pacific Railway main line, and empties into Black Bay on the Ottawa River.

Question: Before the year 2000, which of the films NikhilVinay's had the highest grossing box office sales? Passage 1:AlbanySumner Avenues was a station on the demolished BMT Fulton Street Line. It had 2 tracks and 2 side platforms. It was served by trains of the BMT Fulton Street Line. The station was opened on May 30, 1888, and had connections to the Sumner Avenue Line streetcars. Eastbound trains stopped at Albany Avenue, while westbound trains stopped at Sumner Avenue (now Marcus Garvey Boulevard). The next stop to the east was Troy Avenue. The next stop to the west was Tompkins Avenue. During 1912 and 1924, the Dual Contracts program installed a third track on the Fulton El between Nostrand Avenue and the new Hinsdale Street station. Albany-Sumner Avenues stations were closed during that time. In 1936 the Independent Subway System built an underground Fulton Street Subway station at KingstonThroop Avenues between here and the nearby BrooklynTompkins Avenues Station. The el station became obsolete.
Passage 2:Nikhil and Vinay are both trained in classical music. Singer Anuradha Paudwal discovered the duo and recommended them to Gulshan Kumar, owner of T-Series music company, and director Chandra Barot, who signed them for the 1991 romantic film Pyar Bhara Dil. The song "Banke Kitab Teri" from the film became popular. The duo then went on to compose music for over 20 films. Their initial successes included Bewafa Sanam (1995), a film which was breakthrough for playback singer Sonu Nigam, English Babu Desi Mem (1996), Uff Yeh Mohabbat (1997) and Papa The Great (2000). The duo composed music for two of Sonu Nigam's successful music albums, Jaan (1999) and Yaad (2001). They went on to score music for Anubhav Sinha's box office success Tum Bin which included hit songs such as "Koi Fariyaad", "Chhoti Choti Raatein" and "Tumhare Siva". Some of their other successful ventures include Hum Tumhare Hain Sanam, Aapko Pehle Bhi Kahin Dekha Hai, Muskaan and Kuch Dil Ne Kaha. The duo have also been accused of plagiarism by Pakistani singer Faisal Latif.
Passage 3:Moore met Kim Gordon in 1980 at the final gig of The Coachmen, the band he was in with J.D. King, Daniel Walworth (replaced by Dave Keay), and Bob Pullin. Moore, with Gordon, Anne Demarinis and Dave Keay formed a band, appearing under names like Male Bonding and Red Milk and the Arcadians, before settling on Moore's choice of Sonic Youth just before June 1981. The band played Noise Fest in June 1981 at New York's White Columns gallery, where Lee Ranaldo was playing as a member of Glenn Branca's electric guitar ensemble as well as in duo with David Linton as Avoidance Behavior. Moore invited Ranaldo, who he had known when The Coachmen shared a CBGB stage with Ranaldo's 1970s band The Flux, to join the band. The new threesome played three songs at the festival later in the week without a drummer. Each band member took turns playing the drums, until they met drummer Richard Edson. The band signed to Neutral Records, then to Homestead Records, and then to SST Records.

Question: When did the battle for which Vittorio Veneto is named begin? Passage 1:In the 1990s and 2000s Richards continued to contribute to a wide range of musical projects as a guest artist. A few of the notable sessions he has done include guitar and vocals on Johnnie Johnson's 1991 release Johnnie B. Bad, which he also co-produced; and lead vocals and guitar on "Oh Lord, Don't Let Them Drop That Atomic Bomb on Me" on the 1992 Charles Mingus tribute album Weird Nightmare. He duetted with country legend George Jones on "Say It's Not You" on the Bradley Barn Sessions (1994); a second duet from the same sessions, "Burn Your Playhouse Down", appeared on Jones' 2008 release Burn Your Playhouse Down The Unreleased Duets. He partnered with Levon Helm on "Deuce and a Quarter" for Scotty Moore's album All the King's Men (1997). His guitar and lead vocals are featured on the Hank Williams tribute album Timeless (2001) and on veteran blues guitarist Hubert Sumlin's album About Them Shoes (2005). Richards also added guitar and vocals to Toots & the Maytals' recording of "Careless Ethiopians" for their 2004 album True Love, which won the Grammy Award for Best Reggae Album. Additionally, in December 2007 Richards released a download-only Christmas single via iTunes of "Run Rudolph Run"; and the B-side was a 2003 recorded version of the famous reggae song "Pressure Drop" featuring Toots Hibbert singing with Richards backed by original Maytals band members Jackie Jackson and Paul Douglas.
Passage 2:The San Francisco Estuary is a major stop on the Pacific flyway for migrating waterfowl. Yet little is known about the flow of carbon in or out of the estuary via birds. Millions of waterfowl annually use the bay shallows as a refuge. Most of the birds are dabbling ducks that feed on submerged aquatic vegetation. Diving ducks (such as scaups) feed on epibenthic organisms like C. amurensis, representing a possible flow of carbon from that otherwise dead end. Two endangered species of birds are found here: the California least tern and the California clapper rail. Exposed bay muds provide important feeding areas for shorebirds, but underlying layers of bay mud pose geological hazards for structures near many parts of the bay perimeter. Piscivorous birds such as cormorants and pelicans also inhabit the estuary, but their trophic impact remains poorly studied.
Passage 3:Vittorio Veneto was ordered under the 1934 construction program, and was named for the Battle of Vittorio Veneto, a decisive Italian victory over the Austro-Hungarian Empire in OctoberNovember 1918 during World War I. Her keel was laid on 28 October 1934 at Cantieri Riuniti dell'Adriatico in Trieste, the same day as her sister ship . Vittorio Veneto was launched on 25 July 1937, and major construction was completed by October 1939. The fitting-out process was greatly delayed due to repeated changes to the design and shortages of heavy armor plate. Before she could begin sea trials, Vittorio Veneto was moved to Venice on 4 October to have her bottom cleaned of the fouling that had accumulated during the long fitting-out period, since the Venice Arsenal had the only drydock in Italy long enough to accommodate a ship the size of the Littorio class.
