Gelignite
Gelignite (), also known as blasting gelatin or simply "jelly", is an explosive material consisting of collodion-cotton (a type of nitrocellulose or guncotton) dissolved in either nitroglycerine or nitroglycol and mixed with wood pulp and Potassium nitrate, saltpetre (sodium nitrate or potassium nitrate). It was invented in 1875 by Swedish chemist Alfred Nobel, who also invented dynamite. It is more stable than dynamite, but can still suffer from "sweating" or leaching out nitroglycerine. Its composition makes it plastic explosive, easily moldable and safe to handle without protection, as long as it is not near anything capable of detonating it. One of the cheapest explosives, it burns slowly and cannot explode without a detonator, so it can be stored safely. In the United Kingdom, an explosives certificate, issued by the local Chief Officer of Police, is required for possession of gelignite. Due to its widespread civilian use in Quarry, quarries and mining, it has historically ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Plastic Explosive
Plastic explosive is a soft and hand-moldable solid form of explosive material. Within the field of explosives engineering, plastic explosives are also known as putty explosives or blastics. Plastic explosives are especially suited for explosive demolition. Common plastic explosives include Semtex and C-4 (explosive), C-4. The first manufactured plastic explosive was gelignite in 1875, invented by Alfred Nobel. Usage Plastic explosives are especially suited for explosive demolition of obstacles and fortifications by combat engineers as they can be easily formed into ideal shapes for cutting structural members and have a high enough velocity of detonation and density for metal cutting work. An early use of plastic explosives was in the warhead of the Mortar (weapon)#Spigot mortar, Petard demolition mortar of the British Armoured Vehicle Royal Engineers (AVRE) which was used to destroy concrete fortifications encountered during Operation Overlord (D-Day). The original use of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ulster Volunteer Force
The Ulster Volunteer Force (UVF) is an Ulster loyalism, Ulster loyalist paramilitary group based in Northern Ireland. Formed in 1965, it first emerged in 1966. Its first leader was Gusty Spence, a former Royal Ulster Rifles soldier from Northern Ireland. The group undertook Timeline of Ulster Volunteer Force actions, an armed campaign of almost thirty years during The Troubles. It declared a ceasefire in 1994 and officially ended its campaign in 2007, although some of its members have continued to engage in violence and criminal activities. The group is a proscribed organisation and is on the List of designated terrorist organizations, terrorist organisation list of the United Kingdom. The UVF's declared goals were to combat Irish republicanism, Irish republican paramilitaries – particularly the Provisional Irish Republican Army (IRA) – and to maintain Northern Ireland's status as part of the United Kingdom. It was responsible for more than 500 deaths. The vast majority (m ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mudiad Amddiffyn Cymru
; ), abbreviated as MAC, was a paramilitary Welsh nationalist organisation, which was responsible for a number of bombing incidents between 1963 and 1969. The group's activities primarily targeted infrastructure transporting water to the English people, English cities of Birmingham and Liverpool, in addition to the Investiture of Charles, Prince of Wales, investiture of Charles III as Prince of Wales. History MAC was first established in 1962 at Owain Williams (politician), Owain Williams' café in Pwllheli, Gwynedd. After two years of working as a cattle rancher in Canada, Williams returned to his family farm near Nefyn on the Llŷn Peninsula in 1959. On his return, he had become radicalised by Plaid Cymru's failure to prevent the Tryweryn flooding, flooding of Tryweryn, which was being planned by Liverpool Corporation with the intention of constructing a Llyn Celyn, reservoir supplying water to the city.

Nitroglycerine
Nitroglycerin (NG) (alternative spelling nitroglycerine), also known as trinitroglycerol (TNG), nitro, glyceryl trinitrate (GTN), or 1,2,3-trinitroxypropane, is a dense, colorless or pale yellow, oily, explosive liquid most commonly produced by nitrating glycerol with white fuming nitric acid under conditions appropriate to the formation of the nitric acid ester. Chemically, the substance is a nitrate ester rather than a nitro compound, but the traditional name is retained. Discovered in 1846 by Ascanio Sobrero, nitroglycerin has been used as an active ingredient in the manufacture of explosives, namely dynamite, and as such it is employed in the construction, demolition, and mining industries. It is combined with nitrocellulose to form double-based smokeless powder, used as a propellant in artillery and firearms since the 1880s. As is the case for many other explosives, nitroglycerin becomes more and more prone to exploding (i.e. spontaneous decomposition) as the temperature ...

Alfred Nobel
Alfred Bernhard Nobel ( ; ; 21 October 1833 – 10 December 1896) was a Swedish chemist, inventor, engineer, and businessman. He is known for inventing dynamite, as well as having bequeathed his fortune to establish the Nobel Prizes. He also made several other important contributions to science, holding 355 patents during his life. Born into the prominent Nobel family in Stockholm, Nobel displayed an early aptitude for science and learning, particularly in chemistry and languages; he became fluent in six languages and filed his first patent at the age of 24. He embarked on many business ventures with his family, most notably owning the company Bofors, which was an iron and steel producer that he had developed into a major manufacturer of cannons and other armaments. Nobel's most famous invention, dynamite, was an explosive made using nitroglycerin, which was patented in 1867. He further invented gelignite in 1875 and ballistite in 1887. Upon his death, Nobel donated his fortun ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Explosive Material
An explosive (or explosive material) is a reactive substance that contains a great amount of potential energy that can produce an explosion if released suddenly, usually accompanied by the production of light, heat, sound, and pressure. An explosive charge is a measured quantity of explosive material, which may either be composed solely of one ingredient or be a mixture containing at least two substances. The potential energy stored in an explosive material may, for example, be: * chemical energy, such as nitroglycerin or grain dust * pressurized gas, such as a gas cylinder, aerosol can, or boiling liquid expanding vapor explosion * nuclear energy, such as in the fissile isotopes uranium-235 and plutonium-239 Explosive materials may be categorized by the speed at which they expand. Materials that detonate (the front of the chemical reaction moves faster through the material than the speed of sound) are said to be "high explosives" and materials that deflagrate are sai ...

Provisional Irish Republican Army
The Provisional Irish Republican Army (Provisional IRA), officially known as the Irish Republican Army (IRA; ) and informally known as the Provos, was an Irish republican paramilitary force that sought to end British rule in Northern Ireland, facilitate Irish reunification and bring about an independent republic encompassing all of Ireland. It was the most active republican paramilitary group during the Troubles. It argued that the all-island Irish Republic continued to exist, and it saw itself as that state's army, the sole legitimate successor to the original IRA from the Irish War of Independence. It was List of designated terrorist groups, designated a terrorist organisation in the United Kingdom and an unlawful organisation in the Republic of Ireland, both of whose authority it rejected. The Provisional IRA emerged in December 1969, due to a split within Irish Republican Army (1922–1969), the previous incarnation of the IRA and the broader Irish republican movement. It ...

Truck Hijacking
Carjacking is a robbery in which a motor vehicle is taken over.Michael Cherbonneau, "Carjacking," in ''Encyclopedia of Social Problems'', Vol. 1 (SAGE, 2008: ed. Vincent N. Parrillo), pp. 110-11. In contrast to car theft, carjacking is usually in the presence and knowledge of the victim. A common crime in many places in the world, carjacking has been the subject of legislative responses, criminology studies, prevention efforts as well as being heavily dramatized in major film releases. Commercial vehicles such as trucks and armored cars containing valuable cargo are common targets of carjacking attempts. Carjacking usually involves physical violence to the victim, or using the victim as a hostage. In rare cases, carjacking may also involve sexual assault. Etymology The word is a portmanteau of ''car'' and ''hijacking''. The term was coined by reporter Scott Bowles and editor E. J. Mitchell with ''The Detroit News'' in 1991. ''The News'' first used the term in a report on the mur ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Road Tanker
A tank truck, gas truck, fuel truck, or tanker truck (American English) or tanker (British English) is a motor vehicle designed to carry liquids or gases on roads. The largest such vehicles are similar to railroad tank cars, which are also designed to carry liquid loads. Many variants exist due to the wide variety of liquids that can be transported. Tank trucks tend to be large; they may be insulated or non-insulated; pressurized or non-pressurized; and designed for single or multiple loads (often by means of internal divisions in their tank). Some are semi-trailer trucks. They are difficult to drive and highly susceptible to rollover due to their high center of gravity, and potentially the free surface effect of liquids sloshing in a partially filled tank. History Oil Prior to tank distribution, oil was delivered in cans. From the 1880s, it was distributed in horse-drawn tanks. In 1910, Standard Oil started using motor tankers. Anglo American Oil introduced undergrou ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
