The objective of this paper is to provide an analysis of particulate metal emissions in the USA. The analysis will identify natural and industrial sources, environmental standards, emission trends, and controls of particulate emissions. Since the majority of airborne metal emissions originate from metal industries and electric utility facilities, environmental and worker assessments of exposure...

For traditional heterotrophic denitrification technology, organics are usually added as the electron donor for nitrate removal, which increases operation cost wastewater treatment. Solar panel production contains a large amount of nitrate. To decrease and reduce CO2 emissions, an iron anode microbial fuel cell (Fe-MFC) was constructed to treat solar by sequencing batch operation. The results sh...

This paper introduces the concept of a dynamic key infrastructure for Grid. It utilises the properties of Identity-based Cryptography (IBC) to simplify key management techniques used in current Public Key Infrastructure (PKI) settings for Grid. This approach can offer greater simplicity, flexibility, and enhanced computation trade-offs.
