1Gas-operated reloading — Gas operation is a system of operation used to provide energy to operate autoloading firearms. In gas operation, a portion of high pressure gas from the cartridge being fired is used to power a mechanism to extract the spent case and chamber a… …
2greenhouse gas — any of the gases whose absorption of solar radiation is responsible for the greenhouse effect, including carbon dioxide, methane, ozone, and the fluorocarbons. [1980 85] * * * ▪ atmospheric science Introduction any gas that has the property of… …
3MicroMegas detector — The “Micromegas “ (Micro MEsh Gaseous Structure) detector is a gaseous particle detector coming from the development of wire chamber. Invented in 1992[1] by Georges Charpak and Ioannis Giomataris, the Micromegas detectors are mainly used in… …
4radiation — radiational, adj. /ray dee ay sheuhn/, n. 1. Physics. a. the process in which energy is emitted as particles or waves. b. the complete process in which energy is emitted by one body, transmitted through an intervening medium or space, and… …

6Liquid rocket — A liquid rocket is a rocket with an engine that uses propellants in liquid form. Liquids are desirable because their reasonably high density allows the volume and hence the mass of the tanks to be relatively low, resulting in a high mass ratio.… …
7Environmental scanning electron microscope — Wool fibers imaged in an ESEM by the use of two symmetrical plastic scintillating backscattered electron detectors …
8ESEM — stands for environmental scanning electron microscope. This is a scanning electron microscope (SEM) that allows a gaseous environment in the specimen chamber. Whereas all conventional microscopes operate in vacuum, the ESEM has added a new… …
9global warming — an increase in the earth s average atmospheric temperature that causes corresponding changes in climate and that may result from the greenhouse effect. [1975 80] * * * Potential increase in global average surface temperatures resulting from… …
10Fluorescent lamp — A fluorescent lamp or fluorescent tube is a gas discharge lamp that uses electricity to excite mercury vapor. The excited mercury atoms produce short wave ultraviolet light that then causes a phosphor to fluoresce, producing visible light.Unlike… …
