Identification of optimal filtration conditions for the management of eutrophic waters by freshwater mussels using response surface methodology
Autor: Hwan-Seok Choi, David C. Aldridge, Hyuk Lee, Baik-Ho Kim, Y.K. Kim
Publikováno v: Water and Environment Journal. 33:292-299
The substantial filtration capacity of freshwater mussels makes them attractive tools for environmental management. In this study, we applied a central composite design to estimate independent variables and establish optimal conditions of filtration

Filtration Conditions for the Removal of Organic Matter in Eutrophic Waters by Freshwater Mussels Using Response Surface Methodology
Autor: Hwan-Seok Choi, Baik-Ho Kim, Y.K. Kim, David C. Aldridge, Hyuk Lee
In this study, we applied a central composite design to estimate independent variables and establish optimal conditions of filtration rate and feces production that enhance filtration of suspended organic matter by the freshwater mussels Sinanodonta

Developing Trends of Spinning Process for Manufacturing Thrust Chamber of Launch Vehicle
Autor: Chul-Sung Ryu, Keum-Oh Lee, Seongchan Heo, Younho Choi, Junyoung Kwak, Hwan-Seok Choi
Publikováno v: Journal of the Korean Society of Propulsion Engineers. 19:64-71
Spinning process is generally used for manufacturing axisymme trical, thin-walled thickness and hollow circular cross-section parts. Traditional spinning techn ology is classified to conventional spinning and power spinning(shear spinning and flow fo
