case that brought down South Korean stem cell researcher Hwang Woo Suk early this year”. The Los Angeles Times editorial page bemoaned that, “Science took an unnecessary leap forward Wednesday,” by attempting to find a technological fix to address political and religious objections to stem-cell research. “It’s an impressive advance, but scientists — and society — would be better off if they cou...
متن کاملAn Analysis of Fretting Cracks-ii. Unloading and Reloading Phases
An efastic half-plane containing a su~ace-b~ak~og crack normal to the free surface, subjected to loading by uniform tractions over a given length af its surface, is considered. The tractions consist of pressure, constant in time, and a shear load, varying sinu~idaily in time, both applied adjacent to the crack. This geometry approximates the classical fretting problem with a resulting fatigue c...
متن کاملModeling of piping erosion in loess soils
Extended abstract Introduction Piping erosion is one of the common water erosions usually occurs in soil with low infiltration and soluble minerals that finally changes landscape. Different factors control its occurrence and development. To predict piping occurrence/hazard through modeling, effective factors should be prioritized and considered as inputs of the model. The present study...
متن کاملAutomatic Piping System in Ship
One of the most complicated and time-consuming process in ship production is to determine the optimum route of piping. The automatic system to generate optimum collision free routes for pipes is presented in this paper. In the past, research has been primarily focused on the use of only deterministic or only nondeterministic optimization techniques to find the optimal route. In this paper, the ...
متن کاملFluid Flow in Piping Systems
© 1989 Johnson Controls, Inc. 1 Code No. LIT-351H110 The relationship between the many factors which influence the pressure and flow rate within a hydronic system can sometimes seem very confusing. This report provides a simple systematic approach for analyzing basic hydronic systems. These concepts can later be applied to more complicated systems like those discussed in Engineering Reports H11...
