paragraph_text: The introduction of the guided missile resulted in a significant shift in anti-aircraft strategy. Although Germany had been desperate to introduce anti-aircraft missile systems, none became operational during World War II. Following several years of post-war development, however, these systems began to mature into viable weapons systems. The US started an upgrade of their defences using the Nike Ajax missile, and soon the larger anti-aircraft guns disappeared. The same thing occurred in the USSR after the introduction of their SA-2 Guideline systems.

paragraph_text: In the 1982 Falklands War, the Argentine armed forces deployed the newest west European weapons including the Oerlikon GDF-002 35 mm twin cannon and SAM Roland. The Rapier missile system was the primary GBAD system, used by both British artillery and RAF regiment, a few brand-new FIM-92 Stinger were used by British special forces. Both sides also used the Blowpipe missile. British naval missiles used included Sea Dart and the older Sea Slug longer range systems, Sea Cat and the new Sea Wolf short range systems. Machine guns in AA mountings was used both ashore and afloat.

paragraph_text: Operation Barbarossa (German: "Unternehmen Barbarossa") was the code name for the Axis invasion of the Soviet Union, which started on Sunday, 22 June 1941, during World War II. The operation stemmed from Nazi Germany's ideological aims to conquer the western Soviet Union so that it could be repopulated by Germans (Lebensraum), to use Slavs as a slave labour force for the Axis war effort and to annihilate the rest according to Generalplan Ost, and to acquire the oil reserves of the Caucasus and the agricultural resources of Soviet territories.

paragraph_text: In 1952, the Canadian government formed Atomic Energy of Canada Limited (AECL), a Crown corporation with the mandate to develop peaceful uses of nuclear energy. A partnership was formed between AECL, Ontario Hydro and Canadian General Electric to build Canada's first nuclear power plant, Nuclear Power Demonstration (NPD). The 20 MW NPD started operation in June 1962 and demonstrated the unique concepts of on - power refueling using natural uranium fuel, and heavy water moderator and coolant. These features formed the basis of a fleet of CANDU power reactors (CANDU is an acronym for CANada Deuterium Uranium) built and operated in Canada and elsewhere. Starting in 1961, AECL led the construction of 24 commercial CANDU reactors in Ontario, Quebec, and New Brunswick.

paragraph_text: Operation Torch (initially called Operation Gymnast) was the Anglo - American invasion of French North Africa during the North African Campaign of the Second World War which started on 8 November 1942.

paragraph_text: After receiving feedback from users and incorporating the various design changes requested, including adapting the rifle for use with the heavier Belgian SS109 version of the 5.56×45mm round and improving reliability, the weapon system was accepted into service with the British Armed Forces in 1985 as the SA80. The SA80 family originally consisted of the L85A1 Rifle, the L86A1 Light Support Weapon (LSW), and L98A1 Cadet GP Rifle. The first weapons were issued in October 1985.

paragraph_text: The SA80 is a British family of 5.56 × 45mm NATO small arms, all of which are selective fire, gas - operated assault rifle s. The L85 rifle variant of the SA80 family has been the standard issue service rifle of the British Armed Forces since 1987, replacing the L1A1 variant of the FN FAL. The first prototypes were created in 1976, with production ending in 1994. The A1 variant was significantly upgraded in the early 2000s by Heckler & Koch as the SA80A2 and remains in service as of 2017. In mid-2016 a prototype A3 variant was showcased which further improved on the weapon and is reportedly being considered to extend the out of service date beyond 2025.

paragraph_text: Founded by Charles Lazarus in its modern incarnation in 1957, Toys ``R ''Us traced its origins to Lazarus's children's furniture store, which he started in 1948. He added toys to his offering, and eventually shifted his focus. The company had been in the toy business for more than 65 years and operated around 800 stores in the United States and around 800 outside the US, although these numbers have steadily decreased with time.

paragraph_text: Hydrogen was liquefied for the first time by James Dewar in 1898 by using regenerative cooling and his invention, the vacuum flask. He produced solid hydrogen the next year. Deuterium was discovered in December 1931 by Harold Urey, and tritium was prepared in 1934 by Ernest Rutherford, Mark Oliphant, and Paul Harteck. Heavy water, which consists of deuterium in the place of regular hydrogen, was discovered by Urey's group in 1932. François Isaac de Rivaz built the first de Rivaz engine, an internal combustion engine powered by a mixture of hydrogen and oxygen in 1806. Edward Daniel Clarke invented the hydrogen gas blowpipe in 1819. The Döbereiner's lamp and limelight were invented in 1823.

paragraph_text: The Shorts Blowpipe is a man-portable surface-to-air missile that was in use with the British Army and Royal Marines from 1975. It was superseded by an interim design, Javelin, and later the greatly improved Starstreak.

paragraph_text: Starting in the coal mines, by the mid-19th century elevators were operated with steam power and were used for moving goods in bulk in mines and factories. These steam driven devices were soon being applied to a diverse set of purposes - in 1823, two architects working in London, Burton and Hormer, built and operated a novel tourist attraction, which they called the "ascending room". It elevated paying customers to a considerable height in the center of London, allowing them a magnificent panoramic view of downtown.

paragraph_text: A variation of the incandescent lamp did not use a hot wire filament, but instead used an arc struck on a spherical bead electrode to produce heat. The electrode then became incandescent, with the arc contributing little to the light produced. Such lamps were used for projection or illumination for scientific instruments such as microscopes. These arc lamps ran on relatively low voltages and incorporated tungsten filaments to start ionization within the envelope. They provided the intense concentrated light of an arc lamp but were easier to operate. Developed around 1915, these lamps were displaced by mercury and xenon arc lamps.

Following this, according to some reports, the opposition forces launched an operation to capture the capital, while according to other reports, the military learned of the large-scale rebel operation beforehand and made a preemptive strike. Some reports even suggested the rebels launched the operation prematurely due to their plans being discovered by the security forces.
