the most cost effective means for establishing national and global conservation priorities.” Conservationists are challenged with the problem of protecting a range of species at minimal costs. As such conservationists have to prioritize to help those in most need of assistance or trouble (Myers et al. 2000). Therefore‚ many conservationists have adopted the surrogate species approach as a shortcut to aid with the conservation priority decision (Caro and O’ Doherty 1999). The surrogate species

Gas Compressor Brief Introduction A gas compressor is a mechanical device that increases the pressure of a gas by reducing its volume. Compressors are similar to pumps: both increase the pressure on a fluid and both can transport the fluid through a pipe. As gases are compressible‚ the compressor also reduces the volume of a gas. Liquids are relatively incompressible‚ so the main action of a pump is to pressurize and transport liquids. Types of Compressors Centrifugal compressors Centrifugal

Lab 5 Conservation of Momentum and Energy Abstract The physics laws governing conservation of momentum and mechanical energy were investigated by performing multiple experiments with differing conditions. Conservation laws state energy is to be conserved in systems with no net external forces. Two trials consisted of inelastic collisions and two trials consisted of elastic conditions. Photogate software helped decipher initial and final velocities in order

Gas analysis techniques Terms for gas analysis techniques Concentration The term concentration describes the amount of a substance‚ expressed as mass‚ volume‚ or number of particles in a unit volume of a solid‚ liquid‚ or gaseous substance e.g. alcohol in beer or oxygen in air. Different units are in use to describe concentration in gases: Mass concentration Concentration expressed in terms of mass of substance per unit volume [g substance/m3 gas volume] ¢ Volume concentration Concentration

Energy conservation is a very important part of energy planning and its management. It not only saves energy resources for future‚ avoids wasteful utilisation of energy‚ provides solution to energy crisis and ensures higher per capita availability/ consumption but controls environmental degradation and pollution. New strategy emphasies greater reliance on non-exhaustible and non-conventional sources of energy so as to conserve exhaustible conventional resources like coal‚ petroleum‚ natural gas etc

Mustard Gas During World War I LOST was the original name for mustard gas‚ it was named after Lommel and Steinkopf. They were the first people who proposed this gas to the military to use as a weapon in 1916. Although mustard gas could possibly been developed as early as 1822 by a French chemist‚ Cesar-Mansuete Desperetez. Thirty-two years later Alfred Riche repeated this reaction of the sulfur dichloride and ethylene‚ but both Riche and Desperetez did not note any harsh properties. In 1860‚

How Chromatography Helps The Human Race Chromatography is the separation of a mixture by passing it in solution or suspension or as a vapor (as in gas chromatography) through a medium in which the components move at different rates. “Chromatography is done by making of a mixture move past the solids‚ or across the surface of a solid‚ like paper. The mixture is poured onto a solid surface. As the different components of the liquid run down the solid‚ some of them move more slowly than other. A component

The gas in the natural world follows the specific laws. Different laws have their own explanations and they apply to the real things in this real world. Charles’s Law‚ Boyle’s Law‚ Combined Gas Law‚ Avogadro’s Law and Gay-Lussac Law explain the gas properties and show the scientists how the gas functions. Charles’s Law describes how gases tend to expand when the heat is added. When the temperature increases‚ the volume of the gas increases.
