The waste photographic films/X-ray contains 1.5 2 % (w/w) black metallic silver which is recovered and reused. Around 18-20% of the world's silver needs are supplied by recycling photographic waste. Silver is a precious metal, further silver has wide uses like in jewellery, dentistry, photography, mirrors, optics, industries, etc. So the recovery of silver is beneficial in industrial, chemical ...

The clinical behavior of Concise and Prisma Shield sealants for pit and fissure was analyzed by clinical/photographic evaluation. A hematoxylin-based staining solution was applied to the occlusal surface 7 days, 18 months, 36 months, and 11 years after the occlusal sealing, thus allowing the sealant material on the surface to be checked. At each analysis time, each occlusal surface was photogra...

This paper evaluates the performance of emerging network processors—in particular, designs that employ multiple hardware contexts to hide memory latency— in constructing IP routers. Such processors are designed to forward minimum-sized IP packets at line speeds, with the advantage (over ASIC-based solutions) of being programmable. However, programming such network processors involves two challe...
