Funk And Wagnalls Carbon Dioxide
941 wordsCarbon dioxide lasers are one of the most powerful lasers ever constructed. The word LASER stands for Light Amplification by Stimulated Emission of Radiation. Lasers are devices that amplify light and produce light beams, ranging from infrared to ultraviolet. A light beam is consistent when its waves or photons, increase while mixing together. Laser light can be extremely intense, highly directional and very pure in color. Gas lasers such as the carbon dioxide laser is made active by ultraviolet...

Needles And Syringes Injection Site
1,178 wordsThere is much debate surrounding the question of whether injectable steroids are more or less effective and safe than oral steroids. It is suggested that the oral steroids, which have a special " 17 -? alkyl ated" chemical structure making them active orally and more difficult for the liver to break down, may be more toxic to the liver. In addition, these oral steroids are subject to "first pass metabolism' meaning the liver is exposed to the drug at its highest concentration immediately after i...

Carbon Dioxide Common Type
505 wordsIs fire truly a living thing? It consumes fuel and oxygen, produces heat and waste, it grows and moves. Weather fire is alive or not, it is still dangerous, so you should always treat it with care. There are four main types of fires which are rated in class A, B, C and D. Knowing how to put particular fires out could save your property, someone's life, or your own life. In order to know how to put fires out, you must first know how one starts. For a fire to occur, there must be three things pres...

Detector Amplifier Hybrids Te Cooled Detector Amplifier Hybrids Dia
425 wordsCooling In many cases IR detectors are cooled during use. This cooling effects the spectral response, responsibilty and response speed. Spectral response characteristics of PbS, Pb Se, and HgCdTe (MCT) shift to the long wavelength side with cooling while Ge, In As and In Sb shift to the short wavelength side. Also, note that the response speeds of PbS and Pb Se become slower with cooling. Methods of cooling include thermoelectric cooling and dewar cooling using dry ice, liquid nitrogen, etc. The...

Solid State Lasers Gas Lasers
393 wordsThere are many different types of lasers. The laser medium can be a solid, gas, liquid or semiconductor. Lasers are commonly designated by the type of lasing material employed: Solid-state lasers have lasing material distributed in a solid matrix (such as the ruby or neodymium-yttrium aluminum garnet (YAG) lasers). The neodymium-YAG laser emits infrared light at 1, 064 nanometers (nm). A nanometer is 1 x 10 - 9 meters. Gas lasers (helium and helium-neon, He Ne, are the most common gas lasers) ha...

Gas Chromatography Data Collection
939 wordsGas Chromatography Purpose: The purpose of the gas chromatography lab is to find out how different substances interact with the surface of a solid. Chromatography is a separation technique that depends on the relative distribution of the components of a mixture between a mobile phase and a solid stationary phase. Chromatography measures the tendency of a substance to interact with the surface of a solid or to remain in a mobile phase. When doing a chromatography lab the mobile phase has to be a ...
