Body Centric Wireless Communication (BCWC) has been topic of much research in recent years. In this manuscript, a novel low-cost microstrip patch antenna is designed for on-/off-body communication with a dual-band operation. The proposed structure exhibits a monopole-like radiation pattern at 2.45 GHz and a broadside radiation at 4.8 GHz, simultaneously. Lateral dimensions of 42 mm × 46 mm and ...

Background:As the use of mobile phones is increasing, public concern about the harmful effects of radiation emitted by these devices is also growing. In addition, protection questions and biological effects are among growing concerns which have remained largely unanswered. Stem cells are useful models to assess the effects of radiofrequency electromagnetic fields (RF-EMF) on other cell lines. S...

Radon is a natural radioactive gas produced by the decay of uranium and thorium, which are present in all rocks and soils in small quantities. There are several isotopes of radon, the most important of which are 222Rn (produced from 238U) and 220Rn (produced from thorium). 220Rn is also known as thoron because of its parent radionuclide. In the United Kingdom, it has been shown that 220Rn deliv...

background: the biological effects of radiation on radiology personnel are divided into two groups of deterministic effects and stochastic effects. due to the effects of radiation on health, radiology staff may be afraid of radiation. younger personnel with little work experience, compared with older personnel, have higher level of fear. the fear among radiology personnel, like employees of var...

this paper addresses the combined effects of couple stresses, thermal radiation, viscous dissipation and slip condition on a free convective flow of a couple stress fluid induced by a vertical stretching sheet. the cogley- vincenti-gilles equilibrium model is employed to include the effects of thermal radiation in the study. the governing boundary layer equations are transformed into a system o...

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 gamma r...

Introduction: Radiation-induced bystander effect (RIBE) is a well-known response associated with the induction of radiation effects in non-irradiated cells via signaling of hit ones. As this so-called phenomenon has been largely investigated in low dose levels, few studies focused on higher dose levels such as grid therapy. Grid therapy or spatially fractionated gri...
