The effect of partial slip and temperature dependent fluid properties on the MHD mixed convection flow from a heated, non-linearly stretching surface in the presence of radiation and non-uniform internal heat generation/absorption is investigated. The velocity of the stretching surface was assumed to vary according to power-law form. Thermal transport is analyzed for two types of non-isothermal...

BACKGROUND AND PURPOSE Although abnormal hyperintensities are frequently observed at or around the optic radiation in elderly subjects, no previous reports have mentioned the clinical significance and pathologic changes of these hyperintensities. We evaluated the hyperintensity patterns of the optic radiation and its surrounding structures on T2-weighted MR images and compared these findings wi...

Introduction In this study, effective dose equivalent for the public due to internal exposure to 222radon (222Rn) was evaluated in three regions of Ramsar, a northern coastal city in Iran.                                Materials and Methods Measurements were carried out using a radon monitoring device. Outdoor and indoor radon concentrations were measured within 24 hours with an integration in...

The dynamical evolution of internal space-like dimensions breaks the invariance of the Maxwell’s equations under Weyl rescaling of the (conformally flat) four-dimensional metric. Depending upon the number and upon the dynamics of internal dimensions large scale magnetic fields can be created. The requirements coming from magnetogenesis together with the other cosmological constraints are examin...

Within the framework of radiation protection or internal radiotherapy, one of the major stakes is to determine in a most realistic possible way the dose received by every patient. In this purpose, a tool called OEDIPE, French acronym for “tool for personalized internal dose assessment”, was developed at IRSN associating numerical voxelized phantoms, created with anatomical images, and Monte Car...

The Fukushima Dai-ichi Nuclear Power Plant accident resulted in a release of radionuclides to the environment and a wide range of radioactive contamination. The national government and local governments implemented urgent protective actions to reduce internal exposure from ingestion of food and tap water or inhalation of radionuclides after the accident. There has been some concern in evaluatin...

We present an updated analysis of incidence and mortality from atherosclerotic induced ischemic heart diseases in the cohort of workers at the Mayak Production Association (PA). This cohort constitutes one of the most important sources for the assessment of radiation risk. It is exceptional because it comprises information on several other risk factors. While most of the workers have been expos...

In the dynamic diffusion limit of radiation hydrodynamics, advection dominates diffusion; the latter primarily affects small scales and has negligible impact on the large scale flow. The radiation can thus be accurately regarded as an ideal fluid, i.e., radiative diffusion can be neglected along with other forms of dissipation. This viewpoint is applied here to an analysis of simple waves in an...
