Digestion tank production gas is a biogas produced by artificial anaerobic digestion of organic wastes with bacteria in the digestion tank. This can be divided into mergence gas which produce bio-gas by putting more than two of them together, among the organic waste gas, waste water gas, livestock· sewage gas, sewage sludge gas, depending on the type of organic waste. Because they are artificial
Ⅰ. 서론
박테리아의 게놈에 담긴 정보가 밝혀지기 시작하면서 병원성에 관련된 미생물에 대한 연구가 활발해지고 있다. 특히 이번에 시카고에서 개최된 미국 미생물학회 연례회합에서는 오랫동안 미스터리로 남아있던 살모넬라균의 감염 메커니즘에 대한 연구결과가 보고 되었다.

Synthesis of PVAc and PVA
2.Objective
PVA(poly vinyl alcohol) is prepared by hydrolysis of PVAc, which is synthesized by emulsion polymerization of vinyl acetate.
3.Theory
◇ Background
-PVA
Polyvinyl alcohol has excellent film forming, emulsifying, and adhesive properties. It is also resistant to oil, grease and solvent. It is odorless and nontoxic. It has high tensile

The last efficacy is neurological disorder treatment. its symptoms appeared headache, vertigo, sleeplessness, anxiety, habdabs, loss of appetite, and palpitations.
In those effects, treatment of Neurological disorder is representative effect of W.H.Chungsimwon .

Let's see the process flow of cellulosic ethanol which we are interested in(Figure 1). At the upstream, biomass harvest undergoes a pretreatment and cellulose hydrolysis by enzymes and then fermented to ethanol through the points. The initial contract for each course are as follows.

The Barrett-Joyner-Halenda (BJH) method for calculating pore size distributions is based on a model of the adsorbent as a collection of cylindrical pores. The theory accounts for capillary condensation in the pores using the classic
