Kogalymavia Flight 9268
Metrojet Flight 9268 was an international chartered passenger flight, operated by Russian airline Kogalymavia (branded as Metrojet). On 31 October 2015, at 06:13 local time EST (04:13 UTC), an Airbus A321-231 operating the flight exploded above the northern Sinai Peninsula following its departure from Sharm El Sheikh International Airport, Egypt en route to Pulkovo Airport, Saint Petersburg, Russia. All 224 passengers and crew on board were killed. The cause of the crash was most likely an onboard explosive device as concluded by Russian investigators. Most of the people aboard the flight were tourists. There were 212 Russians, four Ukrainians, and one Belarusian passenger. There were also 7 crew members on board. Investigators believe that a bomb was put on the aircraft at Sharm El Sheikh, with the goal of causing airlines to suspend flights to that airport. Shortly after the crash, the Islamic State's Sinai Branch, previously known as Ansar Bait al-Maqdis, claimed respon ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

President Of Egypt
The president of Egypt is the executive head of state of Egypt and the de facto appointer of the official head of government under the Egyptian Constitution of 2014. Under the various iterations of the Constitution of Egypt following the Egyptian Revolution of 1952, the president is also the supreme commander of the Armed Forces, and head of the executive branch of the Egyptian government. The current president is Abdel Fattah el-Sisi, who has been in office since 8 June 2014. History The first president of Egypt was Mohamed Naguib, who along with Gamal Abdel Nasser, led the Egyptian Revolution of 1952 that overthrew King Farouk and marked the end of the British colonial rule. Though Farouk's infant son was formally declared by the revolutionaries as King Fuad II, all effective executive power was vested in Naguib and the Revolutionary Command Council. On 18 June 1953, just under a year after the coup d'état, the Council abolished the monarchy of Egypt and Sudan, and dec ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
TNT Equivalent
TNT equivalent is a convention for expressing energy, typically used to describe the energy released in an explosion. The is a unit of energy defined by that convention to be , which is the approximate energy released in the detonation of a metric ton (1,000 kilograms) of TNT. In other words, for each gram of TNT exploded, (or 4184 joules) of energy is released. This convention intends to compare the destructiveness of an event with that of conventional explosive materials, of which TNT is a typical example, although other conventional explosives such as dynamite contain more energy. Kiloton and megaton The "kiloton (of TNT)" is a unit of energy equal to 4.184 terajoules (). The "megaton (of TNT)" is a unit of energy equal to 4.184 petajoules (). The kiloton and megaton of TNT have traditionally been used to describe the energy output, and hence the destructive power, of a nuclear weapon. The TNT equivalent appears in various nuclear weapon control treaties, and has b ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Improvised Explosive Device
An improvised explosive device (IED) is a bomb constructed and deployed in ways other than in conventional military action. It may be constructed of conventional military explosives, such as an artillery shell, attached to a detonating mechanism. IEDs are commonly used as roadside bombs, or homemade bombs. IEDs are generally done in these terrorism operations or in asymmetric unconventional warfare by insurgent guerrillas or commando forces in a theatre of operations. In the Iraq War (2003–2011), insurgents used IEDs extensively against U.S.-led forces and, by the end of 2007, IEDs were responsible for approximately 63% of coalition deaths in Iraq. They were also used in Afghanistan by insurgent groups, and caused over 66% of coalition casualties in the 2001–2021 Afghanistan War. IEDs were also used frequently by the Liberation Tigers of Tamil Eelam (LTTE) in Sri Lanka during the Sri Lankan Civil War. Background An IED is a bomb fabricated in an improvised manner ...

Lithium-ion Battery
A lithium-ion or Li-ion battery is a type of rechargeable battery which uses the reversible reduction of lithium ions to store energy. It is the predominant battery type used in portable consumer electronics and electric vehicles. It also sees significant use for grid-scale energy storage and military and aerospace applications. Compared to other rechargeable battery technologies, Li-ion batteries have high energy densities, low self-discharge, and no memory effect (although a small memory effect reported in LFP cells has been traced to poorly made cells). Chemistry, performance, cost and safety characteristics vary across types of lithium-ion batteries. Most commercial Li-ion cells use intercalation compounds as the active materials. The anode or negative electrode is usually graphite, although silicon-carbon is also being increasingly used. Cells can be manufactured to prioritize either energy or power density. Handheld electronics mostly use lithium polymer batteries ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fatigue (material)
In materials science, fatigue is the initiation and propagation of cracks in a material due to cyclic loading. Once a fatigue crack has initiated, it grows a small amount with each loading cycle, typically producing striations on some parts of the fracture surface. The crack will continue to grow until it reaches a critical size, which occurs when the stress intensity factor of the crack exceeds the fracture toughness of the material, producing rapid propagation and typically complete fracture of the structure. Fatigue has traditionally been associated with the failure of metal components which led to the term metal fatigue. In the nineteenth century, the sudden failing of metal railway axles was thought to be caused by the metal ''crystallising'' because of the brittle appearance of the fracture surface, but this has since been disproved. Most materials, such as composites, plastics and ceramics, seem to experience some sort of fatigue-related failure. To aid in predicting t ...

Explosion
An explosion is a rapid expansion in volume associated with an extreme outward release of energy, usually with the generation of high temperatures and release of high-pressure gases. Supersonic explosions created by high explosives are known as detonations and travel through shock waves. Subsonic explosions are created by low explosives through a slower combustion process known as deflagration. Causes Explosions can occur in nature due to a large influx of energy. Most natural explosions arise from volcanic or stellar processes of various sorts. Explosive volcanic eruptions occur when magma rises from below, it has very dissolved gas in it. The reduction of pressure as the magma rises and causes the gas to bubble out of solution, resulting in a rapid increase in volume. Explosions also occur as a result of impact events and in phenomena such as hydrothermal explosions (also due to volcanic processes). Explosions can also occur outside of Earth in the universe in events s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Jet Fuel
Jet fuel or aviation turbine fuel (ATF, also abbreviated avtur) is a type of aviation fuel designed for use in aircraft powered by gas-turbine engines. It is colorless to straw-colored in appearance. The most commonly used fuels for commercial aviation are Jet A and Jet A-1, which are produced to a standardized international specification. The only other jet fuel commonly used in civilian turbine-engine powered aviation is Jet B, which is used for its enhanced cold-weather performance. Jet fuel is a mixture of a variety of hydrocarbons. Because the exact composition of jet fuel varies widely based on petroleum source, it is impossible to define jet fuel as a ratio of specific hydrocarbons. Jet fuel is therefore defined as a performance specification rather than a chemical compound. Furthermore, the range of molecular mass between hydrocarbons (or different carbon numbers) is defined by the requirements for the product, such as the freezing point or smoke point. Kerosene-type jet ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Dabiq (magazine)
''Dabiq'' ( ar, دابق, Dābiq) was an online magazine used by the Islamic State (IS) for Islamic radicalisation and recruitment purposes. It was first published in July 2014 in a number of different languages (including English). ''Dabiq'' itself states the magazine is for the purposes of unitarianism, truth-seeking, migration, holy war and community (''tawhid, manhaj, hijrah, jihad'' and '' jama'ah'' respectively). Details ''Dabiq'' was published by IS via the deep web, although it was widely available online through other sources. The first issue carried the date "Ramadan 1435" in the Islamic Hijri calendar. According to the magazine, its name was taken from the town of Dabiq in northern Syria, which is mentioned in a hadith about Armageddon. IS believes Dabiq is where Muslim and infidel forces will eventually face each other, and that after the crusaders' forces are defeated, the apocalypse will begin. Every issue of ''Dabiq'' contained a quote attributed to Abu Musab al ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Abu Osama Al-Masri
Muhammad Ahmad ’Ali al-Isawi, known as Abu Osama al-Masri ( ar, أبو أسامة المصري) (1972/1973-June 2018) was an Egyptian jihadist and leader of the Islamic State branch in the Sinai Peninsula, known as Wilayat Sinai. History Abu Osama is believed to have been born in North Sinai and grew up in Sharqiya in the Nile Delta. His kunya means 'father of Osama, the Egyptian'. He was said to be 42 years old as of November 2015, making his birth year 1972 or 1973. He is reported to have been a clothing importer who studied at al-Azhar University, a top Sunni institution in Cairo. In October 2014, he was believed to have traveled to Syria with about 20 followers when security forces clamped down on militants after former Egyptian President Mohamed Morsi was deposed in the 2013 Egyptian coup d'état.
