treatment process - saccharification. Then, it can be changed ethanol form through fermentation by yeast or genetically engineered E.coli and we can produce biofuel from that ethanol. Now, the way of decreasing process and cost are studied from a few researchers. So we will show the whole process of the production of bioethanol from algae, and we suggest some solutions for reducing cost and the p
wastewater and recycled activated sludge are introduced typically at several points in the aeration tank. The organic load on the aeration tank, MLSS concentration, and oxygen demand are uniform throughout the tank. An advantage of the CMAS process is the dilution of shock loads that occur in the treatment of industrial wastewaters. The CMAS process is relatively simple to operate but tends to ha

A typhoon is needless to point out. A typhoon forms over the northwestern part of the North Pacific, and 23 typhoons on the average move northward and arrive at Korea. Especially, the typhoons "Rusa" and "Maemi"
PHB`s Separation & Purification
Target of this study conducted to obtain a purely material PHB purification process debris in the damaged cells, and to remove the remaining medium components. PHB has been removed during the refining process with just remove the present efficiency of the overall purification stayed in the 70-80%.

Brief Intro : Intel
The leader in the semiconductor industry is unquestionably Intel. Following Intel’s lead are AMD, Cyrix, Digital, Motorola, etc. in CPU manufacturing. Intel has abandoned memory division back in 1985 as the Japanese firms became more competitive and gained chunk of the world market share. From then on Intel has concentrated on developing microprocessors along with other p
