Question: Besides increased efficiency of power plants, there was an increase in efficiency (between 1950 and 1973) of the railway utilization of this electricity with energy-intensity dropping from 218 to 124 kwh/10,000 gross tonne-km (of both passenger and freight trains) or a 43% drop. Since energy-intensity is the inverse of energy-efficiency it drops as efficiency goes up. But most of this 43% decrease in energy-intensity also benefited diesel traction. The conversion of wheel bearings from plain to roller, increase of train weight, converting single track lines to double track (or partially double track), and the elimination of obsolete 2-axle freight cars increased the energy-efficiency of all types of traction: electric, diesel, and steam. However, there remained a 12–15% reduction of energy-intensity that only benefited electric traction (and not diesel). This was due to improvements in locomotives, more widespread use of regenerative braking (which in 1989 recycled 2.65% of the electric energy used for traction,) remote control of substations, better handling of the locomotive by the locomotive crew, and improvements in automation. Thus the overall efficiency of electric traction as compared to diesel more than doubled between 1950 and the mid-1970s in the Soviet Union. But after 1974 (thru 1980) there was no improvement in energy-intensity (wh/tonne-km) in part due to increasing speeds of passenger and freight trains.
Try to answer this question if possible: What caused the energy efficiency to go up?
Answer: energy-intensity dropping
Question: The library is based at two public sites: the Reading Room at the RIBA's headquarters, 66 Portland Place, London; and the RIBA Architecture Study Rooms in the Henry Cole Wing of the V&A. The Reading Room, designed by the building's architect George Grey Wornum and his wife Miriam, retains its original 1934 Art Deco interior with open bookshelves, original furniture and double-height central space. The study rooms, opened in 2004, were designed by Wright & Wright. The library is funded entirely by the RIBA but it is open to the public without charge. It operates a free education programme aimed at students, education groups and families, and an information service for RIBA members and the public through the RIBA Information Centre.
Try to answer this question if possible: Where are RIBA's Study Rooms located?
Answer: the Henry Cole Wing of the V&A
Question: After its defeat in the 1979 general election the Labour Party underwent a period of internal rivalry between the left represented by Tony Benn, and the right represented by Denis Healey. The election of Michael Foot as leader in 1980, and the leftist policies he espoused, such as unilateral nuclear disarmament, leaving the European Economic Community (EEC) and NATO, closer governmental influence in the banking system, the creation of a national minimum wage and a ban on fox hunting led in 1981 to four former cabinet ministers from the right of the Labour Party (Shirley Williams, William Rodgers, Roy Jenkins and David Owen) forming the Social Democratic Party. Benn was only narrowly defeated by Healey in a bitterly fought deputy leadership election in 1981 after the introduction of an electoral college intended to widen the voting franchise to elect the leader and their deputy. By 1982, the National Executive Committee had concluded that the entryist Militant tendency group were in contravention of the party's constitution. The Militant newspaper's five member editorial board were expelled on 22 February 1983.
Try to answer this question if possible: What year was Michael Foot elected as leader?
Answer: 1980
Question: Parisians tend to share the same movie-going trends as many of the world's global cities, with cinemas primarily dominated by Hollywood-generated film entertainment. French cinema comes a close second, with major directors (réalisateurs) such as Claude Lelouch, Jean-Luc Godard, and Luc Besson, and the more slapstick/popular genre with director Claude Zidi as an example. European and Asian films are also widely shown and appreciated. On 2 February 2000, Philippe Binant realised the first digital cinema projection in Europe, with the DLP CINEMA technology developed by Texas Instruments, in Paris.
Try to answer this question if possible: Who realied the first digital cinema projection in Europe?
Answer:
Philippe Binant
