membrane-based technologies have increasingly been chosen in desalination processes, which is evidenced by the increase of large-scale plants constructed in recent years. indeed, several appropriate strategies should be considered to minimize problems faced during the construction, such as membrane system designs, area requirement, energy requirement, operation and maintenance, and environmenta...

The Cooperative Expendable Micro-Slice Servers (CEMS) project evaluates low cost, low power servers for high-scale internetservices using commodity, client-side components. It is a followon project to the 2007 CIDR paper Architecture for Modular Data Centers [11]. The goals of the CEMS project are to establish that low-cost, low-power servers produce better price/performance and better power/pe...

This paper investigates wage differentials between workers in subcontracting and non-subcontracting firms, using data from a recent survey of small manufacturing firms in Gujranwala, Pakistan. The paper finds that subcontracting workers receive a high wage premium and invokes efficiency wage arguments to explain this differential. The paper argues that due to a client/vendor monitoring problem ...

one of the most important measures, in order to increase animal products and reduce imports, is the industrialization of animal husbandry units, specially the dairy cattle. the condition of milk production would be improved by this industrialization, which is in the direction of increasing the efficiency of milk production units. the purpose of this study is calculate , the efficiency of the tr...
