2000 B.C - The first recorded (The Susruta Samhita, Sanskrit writing) water purification began with the Egyptians. It is said that impure water should be boiled over a fire, heated in the sun, have a hot iron dipped into it or purified by filtration through sand and course gravel.
A major step in the development of desalination technologies came in the 1940s during World War II when various m
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

2005~2008년 4년 동안 강박장애 진료환자 자료를 분석한 결과 10대 청소년층 환자는 2005년 1824명에서 2008년 2878명으로 58% 늘어나 연령대 중 가장 놓은 증가율을 보였다.
10대 청소년층 강박장애 환자가 크게 늘어난 주 원인으로, 과도한 학업 스트레스가 지목되었다.
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%.
PHB Synthesis Pathway
Alcaligenes eutrophus PHB in normal circ
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

Figure 3 A description of passive and active targeting. Blood vessel near tumor is not well organized, and numbers of pores are found. EPR effect is observed only at the tumor tissue. Through this effect, drugs are accumulated.
3. Problem and things to be advanced
We cover the meaning of cancer targeting, and how to target
in an aerobic aquatic environment.
Purpose: to remove settleable organics and floating scum (grease and oils).
Efficiencies:
Suspended solids 50 – 65%
BOD 30 – 35%
Primary clarifiers are either circular or rectangular. They are very similar to sedimentation basins used in water treatment except that scum removal is always provided in addition to sludge collection.

2. The Necessity of sustainability
The recent research show that it demands some expenses in the first stage. But when they pass through some point, it will bring the achievements of corporation.
First, the sustainability is a flow in this period that can not be ignored and the essential factor to compete in this field. The playstaion in Sony lost more than 200 million dollars when the Cadmium,
Ⅰ. 개요
midazolam은 다른 benzodiazepine과 같이 치료 및 안전역이 넓어서 안정효과에 따라 지속 주입을 가감할 수 있으며, 저용량에서는 항불안 및 안정효과가 우세하며 기억 소실 효과가 있으므로, 진정상태를 2~3으로 유지하면서 환기보조기 부조화를 피하고자 midazolam 지속 주입을 이용하였다. 다른 약
