The aim of this review was to evaluate the effect of different preparations of garlic with different methodologies on prevention and control of cardiovascular disorders. Almost 30 articles and abstracts from 1990-2003 were searched through Medline. Most of the studies between 1990-1993 showed the significant reduction of TC by garlic powder but a recent controlled study in 2000 found that consu...

The photoactivity of methanol adsorbed on the anatase TiO2 (101) surface was studied by a combination of scanning tunneling microscopy (STM), temperature-programmed desorption (TPD), X-ray photoemission spectroscopy (XPS), and density functional theory (DFT) calculations. Isolated methanol molecules adsorbed at the anatase (101) surface show a negligible photoactivity. Two ways of methanol acti...

The performance of Genetic Algorithm (GA) depends on various operators. Crossover operator is one of them. Crossover operators are mainly classified as application dependent crossover operators and application independent crossover operators. Effect of crossover operators in GA is application as well as encoding dependent. This paper will help researchers in selecting appropriate crossover oper...

유전 알고리즘과 진화 컴퓨팅을 이용해서 컴퓨터과학 분야와 예술분야를 접목하려는 시도가 있어 왔다. 새로 운 해결방안이나 새로운 패턴을 생성하는 특성을 가진 유전 알고리즘의 특성은 진부한 패턴을 벗어나 참신한 창작물을 만들려고 하는 예술의 특성에 적합할 수 있다. 하지만, 사람들이 예술적 창작물에 공감하기 위해서는 지나치게 생소한 것은 문제가 될 수 있다. 기존의 사람 들의 사고방식과 다른 창작물에서 볼 수 있는 공통된 패 턴 또한 필수적인 요소이다. 본 논문에서는 하이퍼네트워크를 이용하여 음악 생성 에 적용하고자 한다. 하이퍼네트워크는 학습과정에 진화 연산적 요소를 내포하고 있다. 또한 학습 데이터를 통해 서 만들어진 하이퍼에지와 학습 방법을 이용해 기존의 학습데이터에 존재하는 패턴을 학습할 수 있고 ...

Methanol is the second most abundant volatile organic compound in the troposphere and plays a significant role in atmospheric chemistry. While there is consensus about the dominant role of living plants as the major source and the reaction with OH as the major sink of methanol, global methanol budgets diverge considerably in terms of source/sink estimates reflecting uncertainties in the approac...

We estimated kinetic parameters associated with methanol disposition in humans from data reported in the literature. Michaelis-Menten elimination parameters (Vmax = 115 mg/L/hr; Km = 460 mg/L) were selected for input into a semi-physiologic pharmacokinetic model. We used reported literature values for blood or urine methanol concentrations in humans and nonhuman primates after methanol inhalati...

Infrared spectroscopy is used to follow the chemical changes, as a function of temperature, after sequentially adsorbing trimethylaluminum (TMA) and methanol on hydroxylated alumina. Deuterium-labeled methanol is used to distinguish between the chemistry of methyl and methoxy species. To differentiate between methanol adsorbed on TMA-derived sites and on alumina, the adsorption of methanol is s...
