Blasting Gelatin
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 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 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 quarries and mining, it has historically been used by rebel groups such as Mudiad Am ...

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 ...

Mining
Mining is the Resource extraction, extraction of valuable geological materials and minerals from the surface of the Earth. Mining is required to obtain most materials that cannot be grown through agriculture, agricultural processes, or feasibly created Chemical synthesis, artificially in a laboratory or factory. Ores recovered by mining include Metal#Extraction, metals, coal, oil shale, gemstones, limestone, chalk mining, chalk, dimension stone, rock salt, potash, gravel, and clay. The ore must be a rock or mineral that contains valuable constituent, can be extracted or mined and sold for profit. Mining in a wider sense includes extraction of any non-renewable resource such as petroleum, natural gas, or even fossil water, water. Modern mining processes involve prospecting for ore bodies, analysis of the profit potential of a proposed mine, extraction of the desired materials, and final mine reclamation, reclamation or restoration of the land after the mine is closed.

Sean O'Callaghan
Sean O'Callaghan (10 October 1954 – 23 August 2017) was a member of the Provisional Irish Republican Army (IRA), who from the late 1970s to the mid-1980s worked against the organisation from within as a mole for the Irish Government with the Garda Síochána's Special Branch. In the mid-1980s he left the IRA and subsequently voluntarily surrendered to British prosecution for actions he had engaged in as an IRA gunman in the 1970s. Following his release from imprisonment, he published a memoir detailing his life in Irish Republican paramilitarism entitled ''The Informer: The True Life Story of One Man's War on Terrorism'' (1998). Former Irish Prime Minister Garret FitzGerald described O'Callaghan as one of the Irish Government's most important spies operating within the Provisional IRA during the late 20th century's The Troubles. Early life O'Callaghan was born on 26 January 1954, into a family with a Fenian paramilitary history, in Tralee, County Kerry. His paternal grandfat ...

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] |
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] |

Enfield, County Meath
Enfield (), also known as Innfield, is a town in south County Meath, Ireland, situated between Kilcock and Kinnegad and very close to the border with County Kildare. The town is on the Dublin-Sligo railway line. It is located on the R148 regional road, formerly the N4 national primary road connecting Dublin to Connacht. In the 20 years between the 1996 and 2016 census, the population of Enfield grew considerably from just 566 inhabitants to 3,239 people. This increase is due to its location on the commuter belt to Dublin. Similarly to many other dormitory towns in this vicinity, numerous housing estates have been constructed, with 2016 census numbers indicating that 80% of the town's housing stock (826 of 1,024 households) was built between 1991 and 2010. By the 2022 census, population had increased to 3,663.

Booster Charge
An explosive booster is a sensitive explosive charge that acts as a bridge between a (relatively weak) conventional detonator and a low-sensitivity (but typically high-energy) explosive such as TNT. By itself, the initiating detonator would not deliver sufficient energy to set off the low-sensitivity charge. However, it detonates the primary charge (the booster), which then delivers an explosive shockwave that is sufficient to detonate the secondary, main, high-energy charge. Unlike C4 plastic explosive, not all explosives can be detonated simply by inserting a detonator and firing it. An initiator such as a shock tube, cannon fuse, or even a conventional detonator does not deliver sufficient shock to detonate charges comprising TNT, Composition B, ANFO and many other high explosives. Therefore, some form of "booster" is required to amplify the energy released by the detonator so that the main charge will detonate. At first, picric acid was used as a booster to detonate TNT, ...
