Grid computing has been identified as an instrument to fulfil high computational demand, a promising approach for higher resource utilization, and an instrument for cost reduction. The full potential of cost savings can be tapped when incentives are set such that demand is shifted to periods or hardware with lower demand, thereby flattening the demand. To set such incentives, it is mandatory to...

Track Maintenance is crucial for the safe and efficient of railway transportation. After analysis of foreign management techniques for high-speed railway track maintenance, combined with the characteristic of passenger dedicated line in China, this paper has explored new ideas of the information system of passenger dedicated line track maintenance and at the same time researched on the theory a...

objective(s): several beneficial effects have been attributed to the probiotic lactic acid bacteria. it was determined that lactobacilli can exert antiproliferative effects on the various cancer cell lines including colon cancer. effects of lactic acid bacteria on colon cancer may vary from strain to strain and there is a need to find the new probiotic strains with tumor suppressing properties ...

The developmental cell death in the nematode C. elegans is controlled by a simple and dedicated genetic program. This genetic program is evolutionarily conserved in higher organisms, including mammals. However, although mammalian homologs of C. elegans cell death gene products continue to regulate apoptosis, they are no longer dedicated regulators of cell death. On the other hand, multiple cell...
