The paper considers a method for compiling model of the intensity direct and scattered solar radiation on vertical surfaces arbitrary orientation

New type of radiation in crystals is predicted and investigated in computer simulation. It is shown that process of volume reflection of electrons and positrons in bent crystals is accomplished with high-power radiation of photons. Volume reflection radiation has intensity comparable with known channeling radiation, but it is less sensitive to entrance angle and sign of charge of a particle. Si...

The architects of phase I radiochemotherapy development programs impose a semblance of structured radiation "intensity" and adverse event predictability upon radiation-anticancer agent interactions whose natural complexity and improper mixing would otherwise lead to dire health consequences. It is incumbent upon radiation oncology investigators to pledge radiation quality and safety to the part...

60-year-old woman was treated for a brain metastasis. The patient received intensity-modulated radiation therapy (SIB-IMRT) dose of 30 Gy for the whole brain and 40 Gy delivered simultaneously to individual brain metastases in 10 fractions. The present report investigated the influence of applied novel prepared treatment plan, among others the fractionation protocol on the electroencephalogram ...

Background: The study aimed to evaluate the impact of Calligonum extract and US radiation on sperm parametersof cryopreserved human semen samples.Materials and Methods: In this experimental study, twenty-five semen specimens were obtained from healthy semendonors and incubated in human tubal fluid (HTF) medium supplemented with 10% human serum albumin (HSA) for45 minutes...

This paper presents a numerical solution for a changing combustor geometry. The effects of the geometric change on the main parameters of the chamber are considered. For this purpose the original geometry and the new one are simulated numerically by a 3-D CFD code and the results are compared. Finally, comments are presented regarding this change. A model is used for turbulence modeling and a...
