Growth performance and nutrient utilization in black Bengal bucks (Capra hircus) supplemented with graded doses of chromium as chromium chloride hexahydrate
Tarun K. Paul, Sudipto Haldar, Tapan K. Ghosh 대한수의학회 Journal of Veterinary Science 8 Pages
대한수의학회 Journal of Veterinary Science 2005, 제 6권 제 1호 5 33-40 (8 pages)
Black Bengal bucks (Capra hircus) were supplemented with 0, 0.2 or 0.4 mg elemental chromium (Cr) as chromium chloride hexahydrate per day for 70 days. Intake of dry matter (p <0.001), crude protein (p < 0.001) and neutral detergent fiber (p <0.01) increased due to Cr supplementation. The apparent total tract digestibility of dry matter (p <0.01), organic matter (p <0.05), crude protein (p <0.001) and acid detergent fiber (p <0.01) improved and the total body weight gain and the live weight gain... -
Determination on the component arrangement of a hybrid rain garden system for effective stormwater runoff treatment

Low impact development (LID) technology has been recently applied for the treatment of nonpoint source pollutants. Rain garden is one of the widely used LIDs since it utilizes various mechanisms such as biological and physico-chemical treatment to reduce pollutants. However, problem such as clogging has been one of the issues encountered by the rain garden that do not undergo constant maintenance. Therefore, this research was conducted to develop and determine the component arrangement of a rain... -
Characteristics and Fate of Stormwater Runoff Pollutants in Constructed Wetlands
Jawara Christian Alihan, Marla Maniquiz-Redillas, Jiyeon Choi, Precious Eureka Flores, Lee-Hyung Kim 한국습지학회 한국습지학회지 8 Pages

Nonpoint source (NPS) pollution continues to degrade the water quality. NPS pollutants signals high concerns against a sustainable environment. Low impact development (LID) is the leading management practice which regulates and treats stormwater runoff especially in highly impervious urban areas. Constructed wetlands are known to have efficient removal capability of NPS pollutants. Likewise, these LID facilities were intended to maintain the predeveloped hydrologic regime through series of... -
Evaluation on the environmental effects of rain garden treating roof stormwater runoff

In this research, the environmental effects of rain garden when applied to a stormwater runoff originated from a rooftop were evaluated. The rain garden that was utilized as LID represents less than 1% of the catchment area that it drains. Storm event monitoring was conducted from March 2012 to August 2014 on a total of 19 storm events. In the 19 storm events that was monitored only 32% produced an outflow which has a mean rainfall characteristic of approximately 25 mm. With the application of... -

도시화로 인한 불투수층의 증가는 강우시 유출량 증가, 침투량 감소, 증발산량 감소 등을 유발시키고, 다량의 비점오염물 질을 유출시킨다. 이러한 도시화에 의한 환경영향을 최소화하기 위하여 환경부는 2012년 이후 그린빗물인프라(Green Stormwater Infrastructure, GSI)기법을 정책적으로 도입하여 자연적 물순환을 구축하고 비점오염 유출저감을 저감하고자 한 다. 본 연구에서는 자연적 물순환 구축을 통한 비점오염저감을 위하여 다양한 강우사상에 적용 가능한 침투여과기술을 개발하고자 한다. 기술의 실제 적용성 평가에 앞서... -
습윤 모래에서 인장강도의 예측 (I) : 이론
김태형, Kim. Tae-Hyung 한국지반공학회 韓國地盤工學會論文集 9 Pages
한국지반공학회 韓國地盤工學會論文集 2008, Vol.24 No.6 27-35 (9 pages)
낮은 응력 단계에서 모래의 인장강도는 포화도 또는 흡입력에 따라 증가하다. 최대값에 도달한 후 감소한다. 최대인 장강도는 어느 포화도에서든 발생될 수 있다. 본 연구에서는 이러한 습윤 모래의 인장강도를 정확히 예측할 수 있는 이론이 제시되었다. 이 이론은 닫힌 형태의 식으로 pendular, funicular, capillary 세 가지로 구분되는 함수특성곡선 전체 영역을 하나로 통일하여 표현하였다. 낮은 응력 단계에서 내부마찰각 ${phi}_t$, 공기침투압(air entry pressure)의 역수값 ${alpha}$, 간극크기범위변수(pore size spectrum...
