Yenakievo
Yenakiieve ( uk, Єна́кієве, ''Yenákiieve'', ; russian: Ена́киево, ''Yenákiyevo'') is a city in the Donetsk Oblast (province) of eastern Ukraine. It is incorporated as a city of oblast significance (a special status within the region equal to that of a raion (district)). The city stands on the Krynka River about from the oblast's administrative center, Donetsk. Its population is approximately . Yenakiieve is an important regional centre of coal mining, metallurgy, chemical production and manufacturing. The city's outdated industry has caused accidents like that of a gas explosion which occurred in June 2008 at one of Yenakiieve's coal mines. Yenakiieve was founded in 1898 when numerous workers' settlements around the Peter's Iron and Steel Works were united into a single settlement named after . Its first coal mines dated from 1883.

Subdivisions Of Ukraine
The administrative divisions of Ukraine ( Ukrainian: Адміністрати́вний у́стрій Украї́ни, tr. ''Administratyvnyi ustrii Ukrainy'') are subnational administrative divisions within the geographical area of Ukraine under the jurisdiction of the Ukrainian Constitution. Ukraine is a unitary state with three levels of administrative divisions: 27 regions (24 oblasts, two cities with special status and one autonomous republic), 136 raions and 1469 hromadas. The first tier consists of 27 subdivisions, of which there are 24 oblasts, one autonomous republic (Crimea) and two cities with special status (Kyiv and Sevastopol). The second tier includes 136 raions. Ukraine directly inherited its administrative divisions from the local republican administration of the Soviet Union, the Ukrainian Soviet Socialist Republic, and the overall structure did not change significantly from the middle of the 20th century until reforms of July 2020; it was somewhat compl ...

Chemical Industry
The chemical industry comprises the companies that produce industrial chemicals. Central to the modern world economy, it converts raw materials ( oil, natural gas, air, water, metals, and minerals) into more than 70,000 different products. The plastics industry contains some overlap, as some chemical companies produce plastics as well as chemicals. Various professionals are involved in the chemical industry including chemical engineers, chemists and lab technicians. History Although chemicals were made and used throughout history, the birth of the heavy chemical industry (production of chemicals in large quantities for a variety of uses) coincided with the beginnings of the Industrial Revolution. Industrial Revolution One of the first chemicals to be produced in large amounts through industrial processes was sulfuric acid. In 1736 pharmacist Joshua Ward developed a process for its production that involved heating saltpeter, allowing the sulfur to oxidize and combine with ...

War In Donbas (2014–2022)
The War in Donbas, russian: Война на Донбассе was an armed conflict in the Donbas region of Ukraine, part of the broader Russo-Ukrainian War. In March 2014, immediately following the Euromaidan protest movement and subsequent Revolution of Dignity, protests by pro-Russian, anti-government separatist groups arose in the Donetsk Oblast, Donetsk and Luhansk Oblast, Luhansk oblasts of Ukraine, collectively called the Donbas. These demonstrations began around the same time as Russia's Annexation of Crimea by the Russian Federation, annexation of Crimea, and were part of wider 2014 pro-Russian unrest in Ukraine, pro-Russian protests across southern and eastern Ukraine. Declaring the Donetsk People's Republic, Donetsk and Luhansk People's Republic, Luhansk People's Republics (DPR and LPR, respectively), Russian separatist forces in Donbas, armed Russian-backed separatist groups seized government buildings throughout the Donbas, leading to armed conflict with Ukrainian ...

Nuclear Explosions For The National Economy
Nuclear Explosions for the National Economy (russian: Ядерные взрывы для народного хозяйства, Yadernyye vzryvy dlya narodnogo khozyaystva; sometimes referred to as ''Program #7'') was a Soviet program to investigate peaceful nuclear explosions (''PNEs''). It was analogous to the United States program ''Operation Plowshare''. One of the better-known tests was '' Chagan'' of January 15, 1965. Radioactivity from the Chagan test was detected over Japan by both the U.S. and Japan in apparent violation of the 1963 Partial Test Ban Treaty (PTBT). The United States complained to the Soviets, but the matter was dropped. History In November 1949, shortly after the test of their first nuclear device on September 23, 1949, Andrey Vyshinsky, the Soviet representative to the United Nations, delivered a statement justifying their efforts to develop their own nuclear weapons capability. He said: However the USSR did not immediately follow the U.S. lead in 1958 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ferro-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 s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
