Chistye Prudy (Metro)
Chistye Prudy (, ) is a Moscow Metro station in the Basmanny District, Central Administrative Okrug, Moscow. It is on the Sokolnicheskaya Line, between Lubyanka (Moscow Metro), Lubyanka and Krasnye Vorota (Moscow Metro), Krasnye Vorota stations. Chistye Prudy was opened on 15 May 1935 as a part of the first segment of the Metro. The station lies beneath Myasnitskaya Street, close to Turgenevskaya Square and the Clean Ponds, after which the station was named. It was the deepest List of Moscow Metro stations, station in Moscow Metro from 1935 until 1938. History and design Though planned to be a three-vaulted station with a full-length central hall (similar to Krasnye Vorota (Moscow Metro), Krasnye Vorota and Okhotny Ryad (Moscow Metro), Okhotny Ryad), Chistye Prudy was built instead according to a ''London Underground type'' design with two passages at either end of the station connecting the platforms. The outer platform vaults were finished to give the impression that a central h ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Moscow Metro Station
There are 308 active stations of the Moscow Metro. Of these, 271 on Moscow Metro proper, and some additional ones that are marketed by Moscow Metro: 6 stations of Moscow Monorail and 31 stations of the Moscow Central Circle. Two stations have been closed (the old Kaluzhskaya (closed), Kaluzhskaya and the old Pervomayskaya (closed), Pervomayskaya stations). By number of stations the Moscow Metro is ranked 8th, cf. List of metro systems. The deepest station of Moscow Metro, Park Pobedy, is the third-deepest metro station of the world.

Marble
Marble is a metamorphic rock consisting of carbonate minerals (most commonly calcite (CaCO3) or Dolomite (mineral), dolomite (CaMg(CO3)2) that have recrystallized under the influence of heat and pressure. It has a crystalline texture, and is typically not Foliation (geology), foliated (Layered intrusion, layered), although there are exceptions. In geology, the term ''marble'' refers to metamorphosed limestone, but its use in stonemasonry more broadly encompasses unmetamorphosed limestone. The extraction of marble is performed by quarrying. Marble production is dominated by four countries: China, Italy, India and Spain, which account for almost half of world production of marble and decorative stone. Because of its high hardness and strong wear resistance, and because it will not be deformed by temperature, marble is often used in Marble sculpture, sculpture and construction. Etymology The word "marble" derives from the Ancient Greek (), from (), "crystalline rock, shin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sretensky Bulvar
Sretensky Bulvar () is a Moscow Metro station in the Meshchansky District, Central Administrative Okrug, Moscow. It is located on the Lyublinsko-Dmitrovskaya Line, between and stations. Sretensky Bulvar opened on 29 December 2007 after more than 25 years since groundbreaking. History The construction, which began in the late 1980s, has frequently stalled as a result of continuous lack of funds. Only in 2004 did proper funding resume, which allowed finishing the construction. The station opening had been long-awaited, as it is an interchange: Chistye Prudy of the Sokolnicheskaya Line and Turgenevskaya of the Kaluzhsko-Rizhskaya Line. The projected passenger dynamics for the station are 10,800 per hour on entry and 20,100 on exit, which allows for a dramatic occupancy decrease on the Koltsevaya Line, particularly on the Komsomolskaya — Kurskaya path. Design The station, designed by architects N. Shumakov and G. Mun, features a standard Lyublinskaya pylon-trivault des ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Turgenevskaya (Moscow Metro)
Turgenevskaya () is a station on the Kaluzhsko-Rizhskaya Line of the Moscow Metro. Name It was named after Turgenevskaya Square, to which the entrances to the station lead; the square itself was named after a Russian novelist and playwright Ivan Turgenev. Design The station was designed by Ivan Taranov, Yu. Vdovin, and I. Petukhova and opened on 5 January 1972. Turgenevskaya has simple white marble pylons which follow the curve of the station tube and a ceiling composed of reinforced plastic panels. Metal cornices run the length of the station along the base of the ceiling. The walls, which are faced with white and black marble, are decorated with chased brass panels by Kh. Rysin and D. Bodniek. Transfers From this station, passengers can transfer to Sokolnicheskaya Line at Chistye Prudy station and to Lyublinsko-Dmitrovskaya Line at Sretensky Bulvar Sretensky Bulvar () is a Moscow Metro station in the Meshchansky District, Central Administrative Okrug, Moscow.

Sergey Kirov
Sergei Mironovich Kirov (born Kostrikov; 27 March 1886 – 1 December 1934) was a Russian and Soviet politician and Bolshevik revolutionary. Kirov was an early revolutionary in the Russian Empire and a member of the Bolshevik faction of the Russian Social Democratic Labour Party. Kirov became an Old Bolshevik and personal friend to Joseph Stalin, rising through the Communist Party of the Soviet Union ranks to become head of the party in Leningrad and a member of the Politburo. On 1 December 1934, Kirov was shot and killed by Leonid Nikolaev at his offices in the Smolny Institute. Nikolaev and several alleged accomplices were convicted in a show trial and executed less than 30 days later. Kirov's assassination was used by Stalin as a reason for starting the Moscow trials and the Great Purge. Early life Sergei Mironovich Kostrikov was born on in Urzhum in Vyatka Governorate, Russian Empire, as one of seven children born to Miron Ivanovich Kostrikov and Yekaterina Kuzmini ...

Bronze
Bronze is an alloy consisting primarily of copper, commonly with about 12–12.5% tin and often with the addition of other metals (including aluminium, manganese, nickel, or zinc) and sometimes non-metals (such as phosphorus) or metalloids (such as arsenic or silicon). These additions produce a range of alloys some of which are harder than copper alone or have other useful properties, such as strength, ductility, or machinability. The archaeological period during which bronze was the hardest metal in widespread use is known as the Bronze Age. The beginning of the Bronze Age in western Eurasia is conventionally dated to the mid-4th millennium BCE (~3500 BCE), and to the early 2nd millennium BCE in China; elsewhere it gradually spread across regions. The Bronze Age was followed by the Iron Age, which started about 1300 BCE and reaching most of Eurasia by about 500 BCE, although bronze continued to be much more widely used than it is in modern times.

Granite
Granite ( ) is a coarse-grained (phanerite, phaneritic) intrusive rock, intrusive igneous rock composed mostly of quartz, alkali feldspar, and plagioclase. It forms from magma with a high content of silica and alkali metal oxides that slowly cools and solidifies underground. It is common in the continental crust of Earth, where it is found in igneous intrusions. These range in size from dike (geology), dikes only a few centimeters across to batholiths exposed over hundreds of square kilometers. Granite is typical of a larger family of ''granitic rocks'', or ''granitoids'', that are composed mostly of coarse-grained quartz and feldspars in varying proportions. These rocks are classified by the relative percentages of quartz, alkali feldspar, and plagioclase (the QAPF diagram, QAPF classification), with true granite representing granitic rocks rich in quartz and alkali feldspar. Most granitic rocks also contain mica or amphibole minerals, though a few (known as leucogranites) conta ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Kaluzhsko-Rizhskaya Line
The Kaluzhsko-Rizhskaya line (, ) (Line 6; Orange Line) is a line of the Moscow Metro, that originally existed as two separate radial lines, Rizhskaya and Kaluzhskaya opened in 1958 and 1962, respectively. Only in 1971 were they united into a single line as the central section connecting the stations Oktyabrskaya to Prospekt Mira was completed. It was also the first line in Moscow to have a cross-platform transfer. The Rizhsky radius is roughly aligned with a northern avenue Prospekt Mira, while the Kaluzhskiy radius generally follows a southwestern street Profsoyuznaya Ulitsa. Presently, the Kaluzhsko-Rizhskaya line is the third busiest in the Moscow Metro system with a passenger traffic rate of 1.015 million per day. It has a bi-directional length of , and a travel time of 56 minutes, typically it is coloured orange on Metro maps and numbered 6. History The Kaluzhsko-Rizhskaya line was the first one in Moscow to be built in the time of the new epoch, when contrary to the o ...

Soviet Air Defence Forces
The Soviet Air Defence Forces (; ) was the air defence branch of the Soviet Armed Forces. Formed in 1941, it continued being a service branch of the Russian Armed Forces after 1991 until it was merged into the Air Force in 1998. Unlike Western air defence forces, V-PVO was a branch of the military unto itself, separate from the Soviet Air Force (VVS) and Air Defence Troops of Ground Forces. During the Soviet period it was generally ranked third in importance of the Soviet services, behind the Strategic Rocket Forces and the Ground Forces. History Service during Second World War Preparations for creation of the air defence forces started in 1932, and by the beginning of Operation Barbarossa, June 1941, there were 13 PVO zones within the military districts. At the outbreak of war, air defence forces were in the midst of rearmament. Anti-aircraft artillery teams had few of the latest 37 mm automatic and 85 mm guns. Moreover, the troops were deficient in Yak-1s and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Plywood
Plywood is a composite material manufactured from thin layers, or "plies", of wood veneer that have been stacked and glued together. It is an engineered wood from the family of manufactured boards, which include plywood, medium-density fibreboard (MDF), oriented strand board (OSB), and particle board (or chipboard). All plywoods bind resin and wood fibre sheets (cellulose cells are long, strong and thin) to form a composite material. The sheets of wood are stacked such that each layer has its grain set typically (see below) perpendicular to its adjacent layers. This alternation of the grain is called ''cross-graining'' and has several important benefits: it reduces the tendency of wood to split when nailed at the edges; it reduces thickness swelling and shrinkage, providing improved dimensional stability; and it makes the strength of the panel consistent across all directions. There is usually an odd number of plies, so that the sheet is balanced, that is, the surface layers ha ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
