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).

Dual-purpose Motorcycle
A dual-sport motorcycle is a type of street-legal motorcycle that is designed for both on and off-road use. The terms ''all-road,'' ''on/off road,'' and ''dual-purpose'' are also used for this class of motorcycles. Dual-sports are equipped with street-legal equipment such as lights, speedometer, mirrors, horn, license plate mounting, and muffler and can, therefore, be registered and licensed. Evolution of dual-sports The concept of a versatile motorcycle equally at home on dirt and pavement is as old as motorcycling itself. Most roads were still unpaved when motorized bicycles first appeared around 1900. In a sense, all motorcycles at that time were dual-sports, intended to be used on dirt as well as pavement. Advertisements well into the 1920s depict motorcycles on dirt roads, raising clouds of dust. By 1940, most roads in developed countries were paved and motorcycles had become heavier and more oriented to the street. In the 1950s and 1960s British manufacturers such as Tr ...

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 equi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

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 Worl ...

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 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 freight trains there, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Beef Cattle
Beef cattle are cattle raised for meat production (as distinguished from dairy cattle, used for milk production). The meat of mature or almost mature cattle is mostly known as beef. In beef production there are three main stages: cow-calf operations, backgrounding, and feedlot operations. The production cycle of the animals starts at cow-calf operations; this operation is designed specifically to breed cows for their offspring. From here the calves are backgrounded for a feedlot. Animals grown specifically for the feedlot are known as feeder cattle, the goal of these animals is fattening. Animals not grown for a feedlot are typically female and are commonly known as replacement heifers. While the principal use of beef cattle is meat production, other uses include leather, and beef by-products used in candy, shampoo, cosmetics, and insulin. Calving and breeding Besides breeding to meet the demand for beef production, owners also use selective breeding to attain specific trai ...
