Recovery of gold and other valuable metals from electronic scrap involves a complex metallurgical flow sheet and requires state-of-the-art recovery technologies that are available in large-scale, integrated smelter and refinery operations. At the end of their use, electronic and other electrical product scrap offer an important recycling potential for the secondary supply of gold and silver...

hypothermia generates potentially severe complications in operating or recovery room. forced air warmer is effective to maintain body temperature. extremely low frequency electromagnetic field (elf-emf) is harmful to human body and mainly produced by electronic equipment including convective air warming system. we investigated elf-emf from convective air warming device on various temperature se...

RAID has long been established as an effective way to provide highly reliable as well as high-performance disk subsystems. However, reliability in RAID systems comes at the cost of extra disks. In this paper, we describe a mechanism that we have termed RAID0.5 that enables striped disks with very high data reliability but low disk cost. We take advantage of the fact that most disk systems use b...
