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...

background and aims. pregnant women often do not receive proper dental care in emergency visits due to a lack of awareness of the effect of radiation doses and the involved risks for the fetus. the aim of the present study was to assess the awareness of general dentists practicing in tabriz, iran, of the risks involved during exposure to diagnostic dental radiation in pregnant women. materials ...

Relativistically covariant form of equation of motion for real particle (neutral in charge) under the action of electromagnetic radiation is derived. Various formulations of the equation of motion in the proper frame of reference of the particle are used. Main attention is devoted to the reformulation of the equation of motion in the general frame of reference, e. g., in the frame of reference ...

Abstract We report on a new capability added to our general relativistic radiation-magnetohydrodynamics code, Cosmos++ : an implicit Monte Carlo (IMC) treatment for radiation transport. The method is based Fleck-type discretization of the radiation-hydrodynamics equations, but generalized both Newtonian and regimes. A multiple reference frame approach used geodesically transport photon packets ...
