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

2-2. 전착의 정량 계산
Faraday 의 법칙 : 음극에서 환원된 금속 이온의 양을 계산할 수 있다.
: 통전량 : 전류 (Ampere)
: 시간 (sec) : 가수 (equiv. / mole)
: Faraday 상수 (96500 C / equiv.) : 반응 mole

(1) What is material?
Certain provisions of the SEC apply only to matters that are “material” to the financial condition of the company. Therefore, interpretation and application of those provisions relates to the issue of “what is material”.
Item 101 of Regulation S-K requires that companies must disclose material effects that compliance with environmental law will have on earnings, c
1) 원리 및 mechanism
분체의 물성을 강하게 지배하는 것은 입자의 크기 및 분포로서 이상적인 분쇄기는 분쇄용량이 크고, 분쇄생성물의 단위량당 동력소모가 작아야 하며, 원하는 단일입자 또는 입도분포를 가지는 생성물을 얻을 수 있어야 한다. 그 때문에 단립자의 파괴의 mechanism은 분쇄의 기본이다.
The luminol is activated with an oxidant. Hydrogen peroxide solution and sodium hydroxide is
used as the activator. In the presence of an catalyst, the hydrogen peroxide is decomposed to form
oxygen and water. The iron in potassium ferricyanide is a catalyst for the reaction.
When luminol reacts with the sodium hydroxide, a dianion is formed. The oxygen produced from
the hydrogen peroxi
① 식 재료 및 조리식품의 Staphylococcus aureus 오염실태
식육은 S. aureus 식중독 발생의 주요한 원인식품이다. 강호조 등(1997)의 연구에 의하면, 오염된 냉동 우육을 22℃에서 12시간 해동하는 동안 2.37 logCFU/g 이상 증가하고, 25∼30℃에서 5시간이면 식중독을 일으키는데 충분한 독소를 생성하며, 생성된 enterot

Ethanol is nowadays an important product in the fuel market. Its market grew from less than a billion liters in 1975 to more than 39billion liters in 2006 and is expected to reach 100 billion liters in 2015. Less than 4% of the ethanol is produced synthetically from oil, while the rest is produ
• Rise and Fall of Ssangyong
Ssangyong Motor is great progress since the 1970's. SsangYong Motor Company has increased the capital of 15 billion won in 1980. Ssangyong Motor Co. also merged Geohwa and expanded the factory at Pyeongtaek in1985.
In 1991 it started a technology partnership with Daimler-Benz. In 1987, it acquired United Kingdom-based specialty car maker Panther West winds. Ss
Who is interested in the process?
Alongside traditional methods of processing and preserving food, the technology of food irradiation is gaining more and more attention around the world. Although regarded as a new technology by some individuals, research on food irradiation dates back to the turn of the century with the first USA and British patents being issued in 1905 for the use of ionizing
