United Nations Forces
Peacekeeping comprises activities intended to create conditions that favour lasting peace. Research generally finds that peacekeeping reduces civilian and battlefield deaths, as well as reduces the risk of renewed warfare. Within the United Nations (UN) group of nation-state governments and organisations, there is a general understanding that at the international level, peacekeepers monitor and observe peace processes in post-conflict areas, and may assist ex-combatants in implementing peace agreement commitments that they have undertaken. Such assistance may come in many forms, including confidence-building measures, power-sharing arrangements, electoral support, strengthening the rule of law, and economic and social development. Accordingly, the UN peacekeepers (often referred to as Blue Berets or Blue Helmets because of their light blue berets or helmets) can include soldiers, police officers, and civilian personnel. The United Nations is not the only organisation to imple ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Commencement Bay-class Escort Carriers
Graduation is the awarding of a diploma to a student by an educational institution. It may also refer to the ceremony that is associated with it. The date of the graduation ceremony is often called graduation day. The graduation ceremony is also sometimes called: commencement, congregation, convocation or invocation. History Ceremonies for graduating students date from the first universities in Europe in the twelfth century. At that time Latin was the language of scholars. A ''universitas'' was a guild of masters (such as MAs) with licence to teach. "Degree" and "graduate" come from ''gradus'', meaning "step". The first step was admission to a bachelor's degree. The second step was the masters step, giving the graduate admission to the ''universitas'' and license to teach. Typical dress for graduation is gown and hood, or hats adapted from the daily dress of university staff in the Middle Ages, which was in turn based on the attire worn by medieval clergy.

Battle Star
A service star is a miniature bronze or silver five-pointed star inch (4.8 mm) in diameter that is authorized to be worn by members of the eight uniformed services of the United States on medals and ribbons to denote an additional award or service period. The service star may also be referred to as a campaign star or battle star depending on which award the star is authorized for and the manner in which the device is used for the award. Service stars, campaign stars, and battle stars are worn with one point of the star pointing up on the suspension ribbon of a medal or service ribbon. A silver star is worn instead of five bronze stars. A service star is sometimes mistaken for a Bronze Star (Bronze Star Medal) or Silver Star (Silver Star Medal). The service star is also similar to the gold and silver -inch stars that may be authorized to be worn on specific individual decorations of certain services to denote additional decorations. Service stars Expeditionary medals Serv ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Long Beach Naval Shipyard
The Long Beach Naval Shipyard (Long Beach NSY or LBNSY), which closed in 1997, was located on Terminal Island between the city of Long Beach and the San Pedro district of Los Angeles, approximately 23 miles south of the Los Angeles International Airport. The primary role of NSY Long Beach at the time of its closure was overhaul and maintenance of conventionally-powered US Navy surface ships, but it also had served as the homeport for several auxiliary ships during its operating history.

Upon landing in San Diego Bay in 1542, Juan Rodríguez Cabrillo claimed the area for Spain ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Radiation Burn
A radiation burn is a damage to the skin or other biological tissue and organs as an effect of radiation. The radiation types of greatest concern are thermal radiation, radio frequency energy, ultraviolet light and ionizing radiation. The most common type of radiation burn is a sunburn caused by UV radiation. High exposure to X-rays during diagnostic medical imaging or radiotherapy can also result in radiation burns. As the ionizing radiation interacts with cells within the body—damaging them—the body responds to this damage, typically resulting in erythema—that is, redness around the damaged area. Radiation burns are often discussed in the same context as radiation-induced cancer due to the ability of ionizing radiation to interact with and damage DNA, occasionally inducing a cell to become cancerous. Cavity magnetrons can be improperly used to create surface and internal burning. Depending on the photon energy, gamma radiation can cause deep gamma burns, with 60Co in ...

Castle Bravo
Castle Bravo was the first in a series of high-yield thermonuclear weapon design tests conducted by the United States at Bikini Atoll, Marshall Islands, as part of ''Operation Castle''. Detonated on March 1, 1954, the device was the most powerful nuclear weapon, nuclear device detonated by the United States and its first lithium deuteride fueled thermonuclear weapon. Castle Bravo's Nuclear weapon yield, yield was TNT equivalent, , 2.5 times the predicted , due to unforeseen additional reactions involving Isotopes of lithium, lithium-7, which led to the unexpected radioactive contamination of areas to the east of Bikini Atoll. At the time, it was the most powerful artificial explosion in history. Fallout, the heaviest of which was in the form of pulverized surface coral from the detonation, fell on residents of Rongelap Atoll, Rongelap and Utirik Atoll, Utirik atolls, while the more particulate and gaseous fallout spread around the world. The inhabitants of the islands were not evac ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bikini Atoll
Bikini Atoll ( or ; Marshallese: , , meaning "coconut place"), sometimes known as Eschscholtz Atoll between the 1800s and 1946 is a coral reef in the Marshall Islands consisting of 23 islands surrounding a central lagoon. After the Second World War, the atoll's inhabitants were forcibly relocated in 1946, after which the islands and lagoon were the site of 23 nuclear tests by the United States until 1958. The atoll is at the northern end of the Ralik Chain, approximately northwest of the capital Majuro. Three families were resettled on Bikini island in 1970, totaling about 100 residents, but scientists found dangerously high levels of strontium-90 in well water in May 1977, and the residents were carrying abnormally high concentrations of caesium-137 in their bodies. They were evacuated again in 1980. The atoll is occasionally visited today by divers and a few scientists, and is occupied by a handful of caretakers. Etymology The island's English name is deriv ...

Hydrogen Bomb
A thermonuclear weapon, fusion weapon or hydrogen bomb (H bomb) is a second-generation nuclear weapon design. Its greater sophistication affords it vastly greater destructive power than first-generation nuclear bombs, a more compact size, a lower mass, or a combination of these benefits. Characteristics of nuclear fusion reactions make possible the use of non-fissile depleted uranium as the weapon's main fuel, thus allowing more efficient use of scarce fissile material such as uranium-235 () or plutonium-239 (). The first full-scale thermonuclear test was carried out by the United States in 1952; the concept has since been employed by most of the world's nuclear powers in the design of their weapons. Modern fusion weapons consist essentially of two main components: a nuclear fission primary stage (fueled by or ) and a separate nuclear fusion secondary stage containing thermonuclear fuel: the heavy hydrogen isotopes deuterium and tritium, or in modern weapons lithium deu ...

Flash Fire
A flash fire is a sudden, intense fire caused by ignition of a mixture of air and a dispersed flammable substance such as a solid (including dust), flammable or combustible liquid (such as an aerosol or fine mist), or a flammable gas. It is characterized by high temperature, short duration, and a rapidly moving flame front. Definition A flash fire is defined by NFPA 2112 (Standard on Flame-Resistant Clothing for Protection of Industrial Personnel Against Short-Duration Thermal Exposures from Fire) as: :"A type of short-duration fire that spreads by means of a flame front rapidly through a diffuse fuel, such as dust, gas, or the vapors of an ignitable liquid, without the production of damaging pressure." Characterization Flash fires may occur in environments where fuel, typically flammable gas or dust, is mixed with air in concentrations suitable for combustion. In a flash fire, the flame spreads at subsonic velocity, so the overpressure damage is usually negligible and the bulk ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
