Of glowing honey-colored stones. Their shapes ABSTRACT as THE CAMERA EXAMINES air bubbles and crystalline patterns.
MOVING UP AND OVER this amber abstraction, the CAMERA FINDS unusual shapes and imperfections caught in the glassy stone: flecks of dirt, hairs, cracks. STILL MOVING. STARBURSTS OF LIGHT ricochet off the different surfaces of the stones.
CAMERA TURNS along a creamy stretch of amber.
Abstract
Lignocellulosic ethanol production process, pretreatment, saccharification, fermentation, purification is divided into four steps.
The goal of the preprocessing step, after separating from the other ingredients, such as lignin and cellulose, which have the characteristics of hard and complex structures belonging to the upstream process, the microorganisms in the process of sacc
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
2. Objective
1) To investigate of solid-liquid mixture flow characteristics in a slim hole annulus
2) Effect of pipe rotation, fluid property, annulus inclination on the particle transport velocity, transport efficiency and pressure drop
3. Theoretical background
3.1 Reynolds number
Reynolds number can be defined for a number of different situations where a fluid is in relativ
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
물론 이 통계 자료만으로 미혼모와 자녀수를 추정하는 것에는 무리가 있다. 왜냐하면 출산 이후 아이를 입양시키거나 위탁아동으로 보낸 경우가 자녀를 양육하며 단독가구를 구성한 미혼모보다 그 비율이 높기 때문이다. 이런 점에서 혼외 출생아 수는 미혼모의 규모를 보여줄 수 있는 또 다른 통계이

바오디젤은 식물성, 동물성 유지오 같은 재생 가능한 생체 자원으로부터 만들어진다. 바이오디젤은 그 자체만으로도 디젤유를 대체하여 기존 경유요 승용, 승합차에 별도의 엔진 개조 없이 사용될 수 있는 대체 연료이다. 특히 바이오 디젤을 많이 이용하다보면 부산물인 글리세롤을 이용한 활

2. Important Characteristics of TiO2
(1) Photocatalystic Character
- If the light energy is irrigated at TiO2, the catalyst which absorbed the light energy will activate so it oxidize and restore aspirates.
(2) Characteristic of Ultra-hydrophile
- Ultra-hydrophile is the status that befit with the surface of the material such as glass.
For many of Materials, if we drop water, it ma
