A probabilistic risk analysis (PRA) for a high-level radioactive waste repository is very important since it gives an estimate of its health impacts, allowing comparisons to be made with the health impacts of competing technologies. However, it is extremely difficult to develop a credible PRA for a specific repository site because of large uncertainties in future climate, hydrology, geological ...

This paper summarizes the first phase of a study in progress by a committee of the National Research Council's Board on Radioactive Waste Management. The Board initiated the study after observing that statutes and regulations administered by the federal and state agencies that control low-activity radioactive wastes have developed as a patchwork over almost 60 y. These controls usually reflect ...

Since the 19th century, with industrial and urban development and the consequent increase in emissions from industrial activities and vehicular emissions have been observed air pollution effects on living organisms. Thus, since the beginning of the twentieth century, have been carried out several studies that include studies of the effect of pollution on plants (Chies,1983). Some features obser...

Problem statement: An Anaerobic Digestion (AD) process, traditionally applied to wastewater and sewage sludge treatment, has a great potential in the valorization of foodprocessing industry wastes. Approach: This study is focused on the evaluation of the theoretical biogas and methane production of some food wastes, coming out from rice, hazelnut and wine processing, on the grounds of their phy...
