일반 냉장고와 김치냉장고 차이점.
일반냉장고는 간접냉각방식을 택하고 있는데, 냉각된 찬바람을 공급해서, 온도가 떨어지면 냉각을 멈췄다가 온도가 상승하면 다시 냉기를 공급하는 방식입니다.
이러한 이유로 일반 냉장고는 문을 열면 냉기가 빠져나와서 온도가 올라가고, 문을 닫으면 다시

종래의 해양 시추 작업은 고정된 플랜트에서 Oil의 시추 및 정제를 거친 뒤 육상 저장 설비에 보내어 저장하는 방식이었다.
이러한 방식은 플랜트가 시추 및 Well fluid의 정제를 모두 담당하기 때문에 생산 설비를 설치함으로써 플랜트의 덩치가 커지게 되고, 육상 설비에 긴 파이프라인을 연결

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
The atmosphere shields us from the sun's cancer-causing ultraviolet (UV) radiation and also moderates the earth's climate.
The atmosphere is obviously vital for human existence, but we have nevertheless been polluting it for years.
