Abstract
Bioethanol is one of the alternative sources of oil resources which received attention with biodiesel. Many countries produce bioethanol from food sources such as corn and sugarcane, but it causes food-energy conflicts and farmland problem. So it needs to focus on new biomass which is sustainable, renewable, cost-effective and do not occurred any conflicts. Algae are one of the bioma

or a sphere moving in a fluid the internal diameter is generally used today. Other shapes (such as rectangular pipes or non-spherical objects) have an equivalent diameter defined. For fluids of variable density (e.g. compressible gases) or variable viscosity (non-Newtonian fluids) special rules apply. The velocity may also be a matter of convention in some circumstances, notably stirred vessels.

As the preceding paragraphs say, many kinds of food preservation technologies are around for preventing foods from the undesirable results. Specifically this report deals with the methods that i

Wastes in landfill emit landfill gas(LFG) which is mainly composed of carbon dioxide and methane. Methane is one of major green house gases(GHG) with carbon dioxide, and landfill is the important source of it. Otherwise, it can be an alternative energy source due to its high heat value. Therefore, an appropriate use of LFG can derive both of environmental and economical advanta
