We have developed a super compact optical fluorescence spectrometer. Our innovative design combines advantages of guided wave planar optics and free-space microoptics. This innovation allows for miniaturization that is not achievable with pure planar or pure free-space optics. A prototype device has volume of its optical part below 1cm. The spectrometer covers 450nm-650nm spectral range, and pr...

hazardous chemicals may enter the body by inhalation, ingestion, injection or dermal absorption. these exposure routes constitute the overall exposure burden on the body. most occupational exposure studies have focused on measurement of the concentration of air-borne contaminants and other possible routes of exposure are often overlooked. several studies have already highlighted the importance ...

the electronics industry is one of fastest growing manufacturing industries in india. however, the increase in the sales of electronic goods and their rapid obsolescence has resulted in the large-scale generation of electronic waste, popularly known as e-waste. e-waste has become a matter of concern due to the presence of toxic and hazardous substances present in electronic goods which, if not ...

bake-out was executed against the newly constructed apartment buildings using two methods to find out the effect of improvement on the indoor air quality and identify the concentration changes in the indoor air by the bake-out method for 3 months after occupancy. from two methods of bake-out executed before occupying, we did not find any reduction effect on the hazardous substances in the indoo...

BACKGROUND The aim of this study was to provide a scientific method based on Geographical Information System (GIS) regarding all sustainable development measures to locate a proper landfill for disposal of hazardous wastes, especially industrial (radioactive) wastes. METHODS Seven effective factors for determining hazardous waste landfill were applied in Qom Province, central Iran. These crit...
