the currently reactor wreckage in fukushima raised the following important questions: is our knowledge of the possible dangers of ionizing radiation sufficient to warrant special action? what is the role of the medical community in technical radiation accidents from windscale to fukushima? what is the role of the medical community in terrorist radiation attacks? are we prepared for those challe...

In recent decades, due to increasing prices of fossil fuels and environmental pollution resulting from the increased energy demand, researches on renewable energy sources have attracted lots of researcher’s attention. Limited investing sources and environmental issues are important factors effecting electricity generation sector. Minimizing costs and environmental damages are issues being consi...

this study assessed the optimum water need of pepper (capsicum annuum l. cv. california wonder) and the critical irrigation level to be applied in order to achieve a reasonable economic yield in water shortage conditions. in a controlled field experiment involving five different treatments, seasonal evapotranspiration for pepper fluctuated from 89 mm in the severe stress treatment (i0.00) to 1,...

In order to examine radiation-induced proteins in an extremely radio-resistant bacterium, it became possibleto perform comparative proteomic analysis on radio-resistance Bacillus megaterium WHO as a wildtypestrain for the first time. Variation in cellular proteins profiles of the Bacillus megaterium WHO after 5KGy γ-irradiation were analyzed by two-dimensional poly acryl amide...

Background: The increasing use of nuclear radiation for human welfare necessitates the search for new, safe, cost effective radio protectors not only for the personnel’s charged with the responsibility of working or testing with radiations in laboratories, but also for general public. With this view the present study has been undertaken to determine the deleterious effects of sub lethal g...

Radiation-induced normal tissue lesions, once seen as a consequence of loss of proliferative integrity of clonogenic target cells, inevitable and untreatable are now viewed as a result of dynamic interactions between multiple cell lines within a particular tissue that can be intervened. Normal tissue damage is the most important limiting factor in radiotherapy and a major component in the medic...

The attenuation of very high energy γ-rays by pair production on the Galactic interstellar radiation field has long been thought of as negligible. However, a new calculation of the interstellar radiation field consistent with multi-wavelength observations by DIRBE and FIRAS indicates that the Galactic interstellar radiation field is intense. We have made a calculation of the attenuation of very...

in order to evaluate radiation capture and use efficiency and productivity in sole and intercropping of three crops, rapeseed (brassica napus l.), bean (phaseolus vulgaris l.) and corn (zea mays l.), an experiment was conducted in mashhad region during the growing season of 2007-2008. in this study six treatments including three sole cropping of the crops (rapeseed sown in 22 september 2007, co...
