With the Basel ban, imposing restrictions on Trans-boundary movement of hazardous wastes, coming into force with effect from 1.1.1998, the concept of treatment and safe disposal of hazardous wastes (HWs) assumes paramount significance. The annual HW generation in India is estimated at 0.3-0.5 million tonnes. As per the ideal industrial siting criteria in India, the industry should have enough l...

Toxicology research in the nanotechnology area has focused primarily on human inhalation, ingestion or dermal exposure. Less research has been published on the impact to ecological systems resulting from a release of nanomaterials. Environmental laws such as CERCLA ("Superfund") address the release of "hazardous substances" by obligating the party releasing the substance to (a) report the relea...

This paper discusses the present hazardous waste program of 3M Company (Minnesota Mining and Manufacturing Company). 3M's definition of hazardous waste and the company's position on hazardous waste disposal are first considered. The company position is that wherever and whenever the disposal of a waste material threatens the environment or public safety, then that waste should be considered a h...

With many offshore installations in the UK sector of the North Sea now reaching or being in excess of their original anticipated design life, there is a particular need to evaluate approaches to structural integrity management by offshore operators. Ageing processes can affect the structural integrity of the installation and demonstration of adequate performance beyond its original design life ...

since they may expose to inorganic pollutants, drinking waters should be investigated andmonitored in industrialized regions. in this study, drinking water samples taken from eight different locationsin heavily industrialized region of turkey, namely marmara region, were analyzed to determine heavy metaland harmful trace element (fe, co, cd, hg, pb, zn, sb, cu, ba, mo, cr, mn and v) concentrati...

A push-pull ventilation system is effective for hazardous material exhaustion. Although a push-pull ventilation system has advantages over a local exhaust hood, some laborious adjustments are required. The pertinence of the adjustments is uncertain because it is difficult to evaluate the performance of a push-pull ventilation system quantitatively. In this study, a measurement of the capture ef...

While current atmospheric Cherenkov installations consist of only a few telescopes each, future installations will be far more complex. Monte Carlo simulations have become an essential tool for the design and optimisation of such installations. The CORSIKA air-shower simulation code and the sim_telarray code for simulation of arrays of Cherenkov telescopes have been used to simulate several can...

The use of batteries to provide storage for photovoltaic power has been evaluated in various contexts. In gridconnected applications, batteries can serve to provide firm peak-shaving for distributed PV installations. To date, however, the use of batteries from parked electricdrive vehicles (EDV) to provide buffer storage for PV capacity value has not been analyzed. The emerging vehicle to grid ...

Interactive Multimedia Installations (IMIs) are invaluable for the history of art and culture, for media technology and for other disciplines involved in the scientific research and the areas of application. Despite their importance, Interactive Multimedia Installations show some weaknesses that threaten their chance to be preserved long enough to be studied or replicated: (1) they show a compl...

-This paper introduces an optimisation model that may be used for planning wind turbine installations over a global energy scenario. The model follows from the observation that, in most practical cases, installations may have to be made under space constraints, and that this may limit the overall energy output per unit land area. In such cases, it may be wise to install wind turbines of large r...
