Abraham Alikhanov
Abram Isaakovich Alikhanov (; russian: Абрам Исаакович Алиханов, born Alikhanian; 8 December 1970) was a Soviet Armenian experimental physicist who specialized in particle and nuclear physics. He was one of the Soviet Union's leading physicists. Alikhanov studied X-rays and cosmic rays before joining the Soviet atomic bomb project. Between 1945 and 1968 he directed the Institute for Theoretical and Experimental Physics (ITEP) in Moscow, which was named after him in 2004. He led the development of both the first research and the first industrial heavy water reactors in the Soviet Union. They were commissioned in 1949 and 1951, respectively. He was also a pioneer in Soviet accelerator technology. In 1934 he and Igor Kurchatov created a "baby cyclotron", the first "cyclotron" operating outside of Berkeley, California. He was the driving force behind the construction of the 70 GeV synchrotron in Serpukhov (1967), the largest in the world at the time. His br ...

Elizavetpol Governorate
The Elizavetpol Governorate, also known after 1918 as the Ganja Governorate, was a province ('' guberniya'') of the Caucasus Viceroyalty of the Russian Empire, with its capital in Yelisavetpol (present-day Ganja). The area of the governorate stretched and was composed of 1,275,131 inhabitants in 1916. The Elizavetpol Governorate bordered the Erivan Governorate to the west, the Tiflis Governorate and Zakatal Okrug to the north, the Dagestan Oblast to the northeast, the Baku Governorate to the east, and Iran to the south. Geography The area of the governorate includes the southern slope of the main Caucasus range in the northeast, where Mount Bazardüzü and other peaks rise above the snow-line; the arid steppes beside the Kura river, reaching 1000 ft. of altitude in the west and sinking to 100–200 ft. in the east, where irrigation is necessary; and the northern slopes of the Transcaucasian escarpment and portions of the Armenian Highlands, which is intersected towards i ...

Soviet Atomic Bomb Project
The Soviet atomic bomb project was the classified research and development program that was authorized by Joseph Stalin in the Soviet Union to develop nuclear weapons during and after World War II. Although the Soviet scientific community discussed the possibility of an atomic bomb throughout the 1930s, going as far as making a concrete proposal to develop such a weapon in 1940, the full-scale program was not initiated and prioritized until Operation Barbarossa. Because of the conspicuous silence of the scientific publications on the subject of nuclear fission by German, American, and British scientists, Russian physicist Georgy Flyorov suspected that the Allied powers had secretly been developing a "superweapon" since 1939. Flyorov wrote a letter to Stalin urging him to start this program in 1942. Initial efforts were slowed due to the German invasion of the Soviet Union and remained largely composed of the intelligence gathering from the Soviet spy rings working in the U. ...

Née
A birth name is the name of a person given upon birth. The term may be applied to the surname, the given name, or the entire name. Where births are required to be officially registered, the entire name entered onto a birth certificate or birth register may by that fact alone become the person's legal name. The assumption in the Western world is often that the name from birth (or perhaps from baptism or '' brit milah'') will persist to adulthood in the normal course of affairs—either throughout life or until marriage. Some possible changes concern middle names, diminutive forms, changes relating to parental status (due to one's parents' divorce or adoption by different parents). Matters are very different in some cultures in which a birth name is for childhood only, rather than for life. Maiden and married names The French and English-adopted terms née and né (; , ) denote an original surname at birth. The term ''née'', having feminine grammatical gender, can be used ...

Transcaucasus Railway
The Transcaucus Railway (russian: Закавка́зская желе́зная доро́га) was the first railway in South Caucasus.Большая Советская Энциклопедия. Гл. ред. Б. А. Введенский, 2-е изд. Т. 16. Железо — Земли. 1952. 672 стр., илл.; 51 л. илл. и карт. It was funded by the Russian Empire as a strategic railway connecting the Black Sea to the Caspian Sea. The railway would allow the Russian army to have better control of Caucasia. Also with the Trans-Caspian railway, Russia could transport troops from Central Asia much faster. The railway operated as a private company between 1865–1922 and a subsidiary railway of the Soviet Railways from 1922–1991. History Russian Empire (1865-1917) The railway started in 1865 at the port town of Poti on the Black Sea. The railway reached Zestafoni in 1871 and T'bilisi in 1872. The contractor for this part of the line was Messrs G.B. Crawley and Co. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Railroad Engineer
A train driver, engine driver, engineman or locomotive driver, commonly known as an engineer or railroad engineer in the United States and Canada, and also as a locomotive handler, locomotive operator, train operator, or motorman, is a person who drives a train, multiple unit or a locomotive. The driver is in charge of, and is responsible for the mechanical operation of the train, train speed, and all of the train handling (also known as brake handling). In American English, a hostler (also known as a switcher) moves engines around rail yards, but does not take them out on the normal tracks; the British English equivalent is a shunter. Train drivers must follow certain guidelines for driving a train safely. For instance, in general, train drivers are encouraged to favour longer stopping distances as this promotes vehicle health, safety, and passenger comfort. Career progression For many American railroads, the following career progression is typical: assistant conductor ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Russified
Russification (russian: русификация, rusifikatsiya), or Russianization, is a form of cultural assimilation in which non-Russians, whether involuntarily or voluntarily, give up their culture and language in favor of the Russian culture and the Russian language. In a historical sense, the term refers to both official and unofficial policies of the Russian Empire and the Soviet Union with respect to their national constituents and to national minorities in Russia, aimed at Russian domination and hegemony. The major areas of Russification are politics and culture. In politics, an element of Russification is assigning Russian nationals to leading administrative positions in national institutions. In culture, Russification primarily amounts to the domination of the Russian language in official business and the strong influence of the Russian language on national idioms. The shifts in demographics in favour of the ethnic Russian population are sometimes considered as a form ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Yerevan Physics Institute
The A.I. Alikhanyan National Science Laboratory () is a research institute located in Yerevan, Armenia. It was founded in 1943 as a branch of the Yerevan State University by brothers Abram Alikhanov and Artem Alikhanian. It was often referred to by the acronym YerPhI (Yerevan Physics Institute).

Soviet Armenia
The Armenian Soviet Socialist Republic,; russian: Армянская Советская Социалистическая Республика, translit=Armyanskaya Sovetskaya Sotsialisticheskaya Respublika) also commonly referred to as Soviet Armenia or Armenia, ; rus, Армения, r=Armeniya, p=ɐrˈmʲenʲɪjə) was one of the Republics of the Soviet Union, constituent republics of the Soviet Union in December 1922 located in the South Caucasus region of Eurasia. It was established in December 1920, when the Soviet people, Soviets took over control of the short-lived First Republic of Armenia, and lasted until 1991. Historians sometimes refer to it as the Second Republic of Armenia, following the demise of the First Republic. As part of the Soviet Union, the Armenian SSR transformed from a largely agricultural hinterland to an important industrial production center, while its population almost quadrupled from around 880,000 in 1926 to 3.3 million in 1989 due to natural gro ...

U-70 (synchrotron)
U-70 (russian: У-70) is a proton synchrotron with a final energy of 70 GeV, built in 1967 at the Institute for High Energy Physics in Protvino (near Serpukhov, Russia). The accelerator held the world record in beam energy at the time of its construction, and it still is the highest energy accelerator in Russia. In 1970, the U-70 scientists team was awarded the Lenin Prize for the development and commissioning of the synchrotron. Description of the accelerator complex The complex operates in pulsed mode. Protons are accelerated to 30 MeV by linear accelerator URAL-30. Then they are injected into the fast-cyclic booster synchrotron U-1.5 having 100-m perimeter, where protons are accelerated to 1.32 GeV. Then the protons are injected to the U-70. After this, an acceleration cycle takes place for 9 seconds, when protons are accelerated to the maximum energy of 76 GeV, and then, they are extracted from the ring to the secondary beams in the experimental halls. U-70 has perimeter a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cyclotron
A cyclotron is a type of particle accelerator invented by Ernest O. Lawrence in 1929–1930 at the University of California, Berkeley, and patented in 1932. Lawrence, Ernest O. ''Method and apparatus for the acceleration of ions'', filed: January 26, 1932, granted: February 20, 1934 A cyclotron accelerates charged particles outwards from the center of a flat cylindrical vacuum chamber along a spiral path. The particles are held to a spiral trajectory by a static magnetic field and accelerated by a rapidly varying electric field. Lawrence was awarded the 1939 Nobel Prize in Physics for this invention. The cyclotron was the first "cyclical" accelerator. The primary accelerators before the development of the cyclotron were electrostatic accelerators, such as the Cockcroft–Walton accelerator and Van de Graaff generator. In these accelerators, particles would cross an accelerating electric field only once. Thus, the energy gained by the particles was limited by the maximum elec ...

Igor Kurchatov
Igor Vasil'evich Kurchatov (russian: Игорь Васильевич Курчатов; 12 January 1903 – 7 February 1960), was a Soviet physicist who played a central role in organizing and directing the former Soviet program of nuclear weapons. As many of his contemporaries in Russia, Kurchatov, initially educated as a naval architect, was an ''autodict'' in nuclear physics and was brought by Soviet establishment to accelerate the feasibility of the "super bomb". Aided by effective intelligence management by Soviet agencies on American Manhattan Project, Kurchatov oversaw the quick development and testing of the first Soviet nuclear weapon, which was roughly based on the first American device, at Semipalatinsk in Kazakhstan in 1949. Kurchatov, a recipient of many former Soviet honors, had a instrumental role in modern nuclear industry in Russia but his health decline rapidly that is mainly attributed to a 1949 radiation accident in Chelyabinsk-40 (a much more serious ...
