Labor Camp
A labor camp (or labour camp, see spelling differences) or work camp is a detention facility where inmates are forced to engage in penal labor as a form of punishment. Labor camps have many common aspects with slavery and with prisons (especially prison farms). Conditions at labor camps vary widely depending on the operators. Convention no. 105 of the United Nations International Labour Organization (ILO), adopted internationally on 27 June 1957, abolished camps of forced labor. In the 20th century, a new category of labor camps developed for the imprisonment of millions of people who were not criminals ''per se'', but political opponents (real or imagined) and various so-called undesirables under communist and fascist regimes. Some of those camps were dubbed "reeducation facilities" for political coercion, but most others served as backbones of industry and agriculture for the benefit of the state, especially in times of war. Precursors Early-modern states could exploit ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Moscow Metro
The Moscow Metro) is a metro system serving the Russian capital of Moscow as well as the neighbouring cities of Krasnogorsk, Reutov, Lyubertsy and Kotelniki in Moscow Oblast. Opened in 1935 with one line and 13 stations, it was the first underground railway system in the Soviet Union. , the Moscow Metro, excluding the Moscow Central Circle, the Moscow Central Diameters and the Moscow Monorail, has 250 stations (287 with Moscow Central Circle) and its route length is , making it the fifth-longest in the world and the longest outside China. The system is mostly underground, with the deepest section underground at the Park Pobedy station, one of the world's deepest underground stations. It is the busiest metro system in Europe, and is considered a tourist attraction in itself. Operations The Moscow Metro, a state-owned enterprise, is long and consists of 15 lines and 250 stations organized in a spoke-hub distribution paradigm, with the majority of rail lines running radia ...

Moscow Canal
The Moscow Canal (russian: Кана́л и́мени Москвы́), named the Moskva–Volga Canal until 1947, is a canal in Russia that connects the Moskva River with the Volga River. It is located in Moscow itself and in the Moscow Oblast. The canal connects to the Moskva River in Tushino (an area in the north-west of Moscow), from which it runs approximately north to meet the Volga River in the town of Dubna, just upstream of the dam of the Ivankovo Reservoir. The length of the canal is . It was constructed between 1932 and 1937 by 200,000 gulag prisoners, under direction of the Soviet secret police and Matvei Berman. With the canal, Moscow is connected to Russia's Unified Deep Water System, a large system of canals and rivers in European Russia, which created access to five seas: the White Sea, Baltic Sea, Caspian Sea, Sea of Azov, and the Black Sea. As such, it is sometimes called the "port of the five seas" (russian: порт пяти морей). Apart from t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Reinforced Concrete
Reinforced concrete (RC), also called reinforced cement concrete (RCC) and ferroconcrete, is a composite material in which concrete's relatively low tensile strength and ductility are compensated for by the inclusion of reinforcement having higher tensile strength or ductility. The reinforcement is usually, though not necessarily, steel bars ( rebar) and is usually embedded passively in the concrete before the concrete sets. However, post-tensioning is also employed as a technique to reinforce the concrete. In terms of volume used annually, it is one of the most common engineering materials. In corrosion engineering terms, when designed correctly, the alkalinity of the concrete protects the steel rebar from corrosion. Description Reinforcing schemes are generally designed to resist tensile stresses in particular regions of the concrete that might cause unacceptable cracking and/or structural failure. Modern reinforced concrete can contain varied reinforcing materials made of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Military Academies In Russia
Russia has a number of military academies of different specialties. This article primarily lists institutions of the Armed Forces of the Russian Federation rather than those of the Soviet Armed Forces. Russian institutions designated as an "academy" are post-graduate professional military schools for experienced commissioned officers who graduated from higher military school or military training center within civilian university and have some years of active duty service after graduation. Thus, military academies are educational institutions conducting the advance training career commissioned officer programmes. These programmes are named magistratura (russian: магистратура) and take 2 years. Military academies are the second (operational-tactical) level of officer training. Their graduates can be appointed to battalion/regiment/brigade commander or equivalent positions. At the moment, some military academies also conduct programmes for the training of warrant offi ...

Major General
Major general (abbreviated MG, maj. gen. and similar) is a military rank used in many countries. It is derived from the older rank of sergeant major general. The disappearance of the "sergeant" in the title explains the apparent confusion of a lieutenant general outranking a major general, whereas a major outranks a lieutenant. In the Commonwealth of Nations, Commonwealth and in the United States, when appointed to a field command, a major general is typically in command of a Division (military), division consisting of around 6,000 to 25,000 troops (several regiments or brigades). It is a two-star general, two-star rank that is subordinate to the rank of lieutenant general and senior to the rank of brigadier or brigadier general. In the Commonwealth, major general is equivalent to the navy rank of rear admiral. In air forces with a separate rank structure (Commonwealth), major general is equivalent to air vice-marshal. In some countries including much of Eastern Europe, major ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Civil Engineer
A civil engineer is a person who practices civil engineering – the application of planning, designing, constructing, maintaining, and operating infrastructure while protecting the public and environmental health, as well as improving existing infrastructure that may have been neglected. Civil engineering is one of the oldest engineering disciplines because it deals with constructed environment including planning, designing, and overseeing construction and maintenance of building structures, and facilities, such as roads, railroads, airports, bridges, harbors, channels, dams, irrigation projects, pipelines, power plants, and water and sewage systems. The term "civil engineer" was established by John Smeaton in 1750 to contrast engineers working on civil projects with the military engineers, who worked on armaments and defenses. Over time, various sub-disciplines of civil engineering have become recognized and much of military engineering has been absorbed by civil engineering. ...

Caucasian War
The Caucasian War (russian: Кавказская война; ''Kavkazskaya vojna'') or Caucasus War was a 19th century military conflict between the Russian Empire and various peoples of the North Caucasus who resisted subjugation during the Russian conquest of the Caucasus. It consisted of a series of military actions waged by the Russian Imperial Army and Cossack settlers against the native inhabitants such as the Adyghe, Abaza– Abkhaz, Ubykhs, Chechens, and Dagestanis as the Tsars sought to expand. Russian control of the Georgian Military Road in the center divided the Caucasian War into the Russo-Circassian War in the west and the conquest of Chechnya and Dagestan in the east. Other territories of the Caucasus (comprising contemporary eastern Georgia, southern Dagestan, Armenia and Azerbaijan) were incorporated into the Russian Empire at various times in the 19th century as a result of Russian wars with Persia. The remaining part, western Georgia, was taken by the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Aleksei Brusilov
Aleksei Alekseyevich Brusilov ( rus, Алексе́й Алексе́евич Бруси́лов, p=ɐlʲɪkˈsʲej ɐlʲɪkˈsʲejɪvʲɪdʑ brʊˈsʲiɫəf; – 17 March 1926) was a Russian and later Soviet general most noted for the development of new offensive tactics used in the 1916 Brusilov Offensive, which was his greatest achievement. The innovative and relatively successful tactics used were later copied by the Germans. Born into the aristocracy to a father who was also a general, Brusilov trained as a cavalry officer, but by 1914 he realized that cavalry was obsolete in the new style of warfare because of its vulnerability to machine gun and artillery. Historians portray him as the only First World War Russian general capable of winning major battles. However, his heavy casualties seriously weakened the Russian army, which was unable to replace its losses. Despite his prominent role in the Imperial Russian Army, he sided with the Bolsheviks in the Russian Civil War an ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
General Officer
A general officer is an officer of high rank in the armies, and in some nations' air forces, space forces, and marines or naval infantry. In some usages the term "general officer" refers to a rank above colonel."general, adj. and n.". OED Online. March 2021. Oxford University Press. https://www.oed.com/view/Entry/77489?rskey=dCKrg4&result=1 (accessed May 11, 2021) The term ''general'' is used in two ways: as the generic title for all grades of general officer and as a specific rank. It originates in the 16th century, as a shortening of ''captain general'', which rank was taken from Middle French ''capitaine général''. The adjective ''general'' had been affixed to officer designations since the late medieval period to indicate relative superiority or an extended jurisdiction. Today, the title of ''general'' is known in some countries as a four-star rank. However, different countries use different systems of stars or other insignia for senior ranks.
