ABSTRACT Thermal power stations produce enormous quantitie s of coal ashes (fly ash and bottom ash) as by- products of coal combustion. This requires the development of technological processes, which will ensure consumption of coal ashes in bulk. Among the various uses of coal ashes, its bulk utilization is possible only in geotechnical engineering...

Transport is a major contributor to greenhouse gas (GHG) emissions, accounting for about 14 percent of the global total, and is the only sector of the world economy in which carbon emissions have risen consistently since 1990. Indeed, transport sector emissions grew by 1.4 billion tons (31 percent) worldwide between 1990 and 2003. This has resulted...
