Dual-use Technology
In politics, diplomacy and export control, dual-use items refer to goods, software and technology that can be used for both civilian and military applications.''Exporting dual-use goods.'' European Commission (accessed Aug 2022) More generally speaking, dual-use can also refer to any goods or technology which can satisfy more than one goal at any given time. Thus, expensive technologies originally benefitting only military purposes would in the future also be used to serve civilian commercial interests if they were not otherwise engaged, such as the Global Positioning System developed by the U.S. Department of Defense. The "dual-use dilemma" was first noted with the discovery of the process for synthesizing and mass-producing ammonia which revolutionized agriculture wi ...

Dual-purpose Gun
A dual-purpose gun is a naval artillery mounting designed to engage both surface and air targets. Description Second World War-era capital ships had four classes of artillery: the heavy main battery, intended to engage opposing battleships and cruisers of 305 mm to 457 mm (12 inch to 18 inch); a secondary battery for use against enemy destroyers of 152 mm to 203 mm (6 inch to 8 inch); heavy anti-aircraft guns of 76 mm to 127 mm (3 inch to 5 inch), which could create barrages to knock out airplanes at a distance; finally, light rapid-fire anti-aircraft batteries (A/A) to track and bring down aircraft at close range. The light A/A was dispersed throughout the ship and included both automatic cannons of 20 mm to 40 mm (.787 inch to 1.57 inch) and heavy machine guns of 12.7 mm to 14.5 mm (.50 inch to .58 inch). During World War II, the US Navy, Royal Navy, the French Navy, and the Imperial Japanese Navy combined the secondary bat ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Dual-Purpose Improved Conventional Munition
A dual-purpose improved conventional munition (DPICM) is an artillery or surface-to-surface missile warhead designed to burst into submunitions at an optimum altitude and distance from the desired target for dense area coverage. The submunitions use both shaped charges for the anti-armor role, and fragmentation for the antipersonnel role, hence the nomenclature "dual-purpose". Some submunitions may be designed for delayed reaction or mobility denial ( mines). The air-to-surface variety of this kind of munition is better known as a cluster bomb. They are banned by more than 100 countries under the Convention on Cluster Munitions. United States DPICM projectiles Development work for DPICM projectiles began in the late 1950s. The first projectile, the 105 mm M444, entered service in 1961. Its submunitions were simple bounding anti-personnel grenades (ICM). Production of the M444 ended in the early 1990s. The first true DPICM was the 155 mm M483, produced in the 1 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Dual Purpose Ladder (London Fire Brigade)
Fire services in the United Kingdom use a variety of fire appliances, which perform a wide range of general and specialised roles and fit into several distinct categories. Contemporary fire appliances carry a multitude of equipment and firefighting media (such as water and foam) to deal with different types of emergencies ranging from fires, rescues, vehicle extrication, floods, salvage, casualty and trauma care. The design and size of a fire appliance depends very much upon the role it is expected to perform. In general, most fire and rescue services use a standardised range of vehicles and equipment. However, airport fire services tend to use much larger and heavier appliances than those typically deployed by public fire services. Most front line fire appliances in the UK are marked in high conspicuity red and yellow battenburg markings, and are fitted with blue lights and sirens. Many appliances have roller shutter doors revealing compartments housing various items of eq ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Using this weapon requires the soldier to close right in with his enemy. The fact that its use is going to be bloody and horrible means that only a strong or well conditioned individual is going to be able to use it in anger." The combat knife and the trench knife are examples of military fighting knives.Peterson, Harold L., ''Daggers and Fighting Knives of the Western Wor ...

Viaduct
A viaduct is a specific type of bridge that consists of a series of arches, piers or columns supporting a long elevated railway or road. Typically a viaduct connects two points of roughly equal elevation, allowing direct overpass across a wide valley, road, river, or other low-lying terrain features and obstacles. The term ''viaduct'' is derived from the Latin ''via'' meaning "road", and ''ducere'' meaning "to lead". It is a 19th-century derivation from an analogy with ancient Roman aqueducts. Like the Roman aqueducts, many early viaducts comprised a series of arches of roughly equal length. Over land The longest viaduct in antiquity may have been the Pont Serme which crossed wide marshes in southern France. At its longest point, it measured 2,679 meters with a width of 22 meters. Viaducts are commonly used in many cities that are railroad hubs, such as Chicago, Birmingham, London and Manchester. These viaducts cross the large railroad yards that are needed for freigh ...

Poultry Farming
Poultry farming is the form of animal husbandry which raises domesticated birds such as chickens, ducks, turkeys and geese to produce meat or eggs for food. Poultry – mostly chickens – are farmed in great numbers. More than 60 billion chickens are killed for consumption annually. Chickens raised for eggs are known as layers, while chickens raised for meat are called broilers. In the United States, the national organization overseeing poultry production is the Food and Drug Administration (FDA). In the UK, the national organization is the Department for Environment, Food and Rural Affairs (DEFRA). Intensive and alternative According to the World Watch Institute, 74 percent of the world's poultry meat, and 68 percent of eggs are produced intensively.''State of the World 2006'' World Watch Institute, p. 26 One alternative to intensive poultry farming is free-range farming using lower stocking densities. Poultry producers routinely use nationally approved medications, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
