Bacterium strain, K-173-10, which was isolated from waste soil of Korean brewing factories, could grow on acetate as the sole carbone source and accumulate a considerable amount of L-glutamic acid (24g/l) in the liguid culture medium. This strain was named by Brevibacterium ammoniagenes sp. by the standard method of taxonomy procedures given in the Manual of Microbiogical Methods.

This survey was performed to measure concentrations of airborne microbes, utilizing the six-stage cascade air sampler, according to the sampling site and time in the general hospital and to evaluate the degree of correlations between airborne microbes and environmental factors. Besides the main lobby, airborne microbes and environmental factors were not significantly different between the forenoon(9:00-10:00 AM) and afternoon(2:00-3:00 PM). Concentrations of airborne bacteria and fungi were 404 and $156CFU/m^3$ in the main lobby, 188 and $56CFU/m^3$ in the intensive care unit, 323 and $96CFU/m^3$ in the ward, 239 and $127CFU/m^3$ in the laboratory, and 139 and $33CFU/m^3$ in the newborn baby room, respectively. As a result, the level of airborne microbes was significantly highest in the main lobby and lowest in the newborn baby room(p<0.05). Outdoor airborne microbes concentrations were significantly lower than those of the sampling sites in the general hospital except for the newborn baby room(p>0.05). It was observed that temperature, relative humidity and carbon dioxide in the general hospital had generally positive correlation with airborne microbes. However, there was no correlation between the odor index level and airborne microbes.

For the fabrication of the Si negative electrode in Li-ion batteries (LIBs) containing the cross-linking polymer binder, in this work, the urethane acrylate (UA) oligomer was synthesized via a simple synthetic process. The cross-linked poly(urethane acrylate) (CPUA)/carbone black (CB)/Si composite (CPUA/CB/Si composite) was fabricated through reactions between their reactive vinyl segments in the UA oligomer. Interestingly, the CPUA/CB/Si composite showed better cycle performance than the poly(vinylidene fluoride) (PVdF)/CB/Si composite (PVdF/CB/Si composite) and the polyurethane (PU)/CB/Si composite (PU/CB/Si composite). The CPUA/CB/Si composite had the best lithiation of about $2586mAh\;g^{-1}$. The UA oligomer showed a good compatibility with the electrode materials and current collector after and before a curing process.

최근 자동차 대체 연료로 가솔린에 10% 무수에탄올이 혼합된 Gasohol 사용에 관한 관심이 고조되고 있으며, 이는 Gasohol이 자동차 배기 가스중의 일산화탄소 및 탄화수소 함유량을 감소시켜 대기 오염을 줄일 수 있기 때문이다. Gasohol에 사용되는 무수에탄올의 농도는 99.5% 이상이어야 하며, 이러한 고순도의 에탄올을 제조하기 위해서는 물과 에탄올의 공비 혼합물(95.6% 에탄올)로부터 공비증류, 분자체 흡착, 투과증발과 같은 분리 조작을 이용하여 물을 제거하는 공정이 필요하다. 현재 에탄올 탈수에는 공비증류가 많이 사용되고 있으나 공비증류는 에너지 사용량이 많을 뿐더러 유독한 Entrainer를 첨가하기 때문에 투과증발과 같은 저 에너지 소비형, 환경친화적인 공정으로의 전환이 이루어지고 있다. 에탄올 탈수용 투과증발 플랜트는 전세계 20여개가 가동되고 있으며, 상업화된 플랜트의 대부분은 독일의 Deutsche Carbone사가 제조한 PVA/PAN 투과증발 복합막을 사용하고 있다. 투과증발 시스템은 물에 대한 친화도가 높은 투과증발막 및 모듈, 기타 분리 구동력을 높여주기 위한 Heater, 진공펌프, 냉각기, 열 교환기 등의 주변 설비로 구성되며, 투과증발 시스템 개발을 위해서는 우수한 막/모듈 제조와 아울러 최적 공정 설계 기술 개발이 필수적이라 하겠다.

Insect/worm is a source of protein food, more calcium than you think, made up of low-fat and high protein in the worms, 20% of the entire protein, nutrients, and so. because of this, the value of any insect food will rise. Is not argued that enough, livestock methane from gaseous material of the earth temperature no phi but not small role, and indeed. If a non-carbone missions from livestock are less and consequently the production of biofuels using worms because it is also expected to be available to the worms in cattle, such as no benefit is expected that you will be spotlighted.
