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 کاملAcoustic emission monitoring for inspection of seam-welded hot reheat piping in fossil power plants
Although failure of the seam weld on reheat steam piping has been an infrequent occurrence, such failure is still a major safety concern for fossil plant operations. EPRI has provided guidelines for a piping management program based on periodic inspection. More recently, EPRI has also sponsored research to develop inspection techniques to both improve the quality and reduce the cost of piping i...
متن کاملPIPing on lysosome tubes.
The role of lysosomes in important cellular responses, including phagocytosis, cell surface repair, and autophagy underlies a number of human diseases. Furthermore, the role of the lysosomal surface in TORC1 signalling has revealed unexpected properties of these organelles. In this issue, Sridhar et al (2013) uncover an important role for PI(4)P for lysosome function under normal nutrient condi...
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...
