The Russian Soviet Federative Socialist Republic (Russian SFSR), previously known as the Russian Socialist Federative Soviet Republic (RSFSR) and the Russian Soviet Republic, and unofficially as Soviet Russia, was a socialist state from 1917 to 1922, and afterwards the largest and most populous constituent republic of the Soviet Union (USSR) from 1922 to 1991, until becoming a sovereign part of the Soviet Union with priority of Russian laws over Union-level legislation in 1990 and 1991, the last two years of the existence of the USSR. The Russian SFSR was composed of sixteen smaller constituent units of autonomous republics, five autonomous oblasts, ten autonomous okrugs, six krais and forty oblasts. Russians formed the largest ethnic group. The capital of the Russian SFSR and the USSR as a whole was Moscow and the other major urban centers included Leningrad (Petrograd until 1924), Stalingrad (Volgograd after 1961), Novosibirsk, Sverdlovsk, Gorky and Kuybyshev.

On 7 November 1917 [O.S. 25 October], as a result of the October Revolution, the Russian Soviet Republic was proclaimed as a sovereign state and the world's first constitutionally socialist state guided by communist ideology. The first constitution was adopted in 1918. In 1922, the Russian SFSR signed a treaty officially creating the USSR. On 12 June 1990, the Congress of People's Deputies adopted the Declaration of State Sovereignty. On 12 June 1991, Boris Yeltsin, supported by the Democratic Russia pro-reform movement, was elected the first and only President of the RSFSR, a post that would later become the Presidency of the Russian Federation. The August 1991 Soviet coup d'état attempt in Moscow with the temporary brief internment of President Mikhail Gorbachev destabilised the Soviet Union. Following these events, Gorbachev lost all his remaining power, with Yeltsin superseding him as the pre-eminent figure in the country. On 8 December 1991, the heads of Russia, Ukraine and Belarus signed the Belovezha Accords declaring dissolution of the USSR and established the Commonwealth of Independent States (CIS) as a loose replacement confederation. On 12 December, the agreement was ratified by the Supreme Soviet (the parliament of the Russian SFSR); therefore the Russian SFSR had renounced the Treaty on the Creation of the USSR and de facto declared Russia's independence from the USSR itself and the ties with the other Soviet republics.

HSE University (Russian: «Высшая школа экономики», ВШЭ), officially the National Research University Higher School of Economics (Russian: Национальный исследовательский университет «Высшая школа экономики») is a public research university founded in 1992 and headquartered in Moscow, Russia. Along with its main campus located in the capital, the university maintains three other regional campuses in Nizhny Novgorod, Perm and Saint Petersburg. It also has an online campus. There is also the Lyceum at HSE University in Moscow.

The Nizhny Novgorod Kremlin (Russian: Нижегородский кремль, romanized: Nizhegorodskiy kreml') is a fortress (kremlin) in the historic city center of Nizhny Novgorod, Russia.

The Time of Troubles (Russian: Смутное время, romanized: Smutnoye vremya), also known as Smuta (Russian: Смута, lit. 'troubles'), was a period of political crisis in Russia which began in 1598 with the death of Feodor I, the last of the House of Rurik, and ended in 1613 with the accession of Michael I of the House of Romanov at the 1613 Zemsky Sobor.

It was a period of deep social crisis and lawlessness following the death of Feodor I, a weak and possibly intellectually disabled ruler who died without an heir. His death ended the Rurik dynasty, leading to a violent succession crisis with numerous usurpers and false Dmitrys (impostors) claiming the title of tsar. Russia experienced the famine of 1601–1603, which killed almost a third of the population, within three years of Feodor's death. Russia was also occupied by the Polish–Lithuanian Commonwealth during the Polish–Russian War and lost Smolensk.

The Unified Deep Water System of European Russia (Russian: Единая глубоководная система Европейской части Российской Федерации, romanized: Yedinaya glubokovodnaya sistema Yevropeyskoy chasti Rossiyskoy Federatsii) or UDWS (Russian: ЕГС) is a system of inland waterways in Russia linking the White Sea, the Baltic Sea, the Volga River, Moscow, the Caspian Sea and—via the Sea of Azov—the Black Sea. In 2010, UDWS carried 70 million tons of cargo and 12 million passengers, making up two-thirds of overall inland waterway traffic volume in Russia. There are 60 common-use ports and quays in the UDWS, including three international ports (two in Moscow and one in Dmitrov, Moscow Oblast), so Moscow is sometimes called "the port of the five seas".

The depth is mostly guaranteed at only 4 metres (13 ft) and some sections are even shallower, such as Gorodets–Nizhny Novgorod at 2.5 metres (8.2 ft) and Kochetovsky Bagayevskaya at 3.2 metres (10 ft). There are plans to increase depth of these sections to 4 m.

The waterfront area of a city or town is its dockland district, or the area alongside a body of water.

In structural engineering, a tensile structure is a construction of elements carrying only tension and no compression or bending. The term tensile should not be confused with tensegrity, which is a structural form with both tension and compression elements. Tensile structures are the most common type of thin-shell structures.

Most tensile structures are supported by some form of compression or bending elements, such as masts (as in The O₂, formerly the Millennium Dome), compression rings or beams.
