Objective (s): Recently, the use of nanoparticles in medicine has increased for radiation protection purpose. So the aim of this study was application of nano Bi2O3 in prepared shield for dose reduction during medical imaging.Materials and Methods: Nano Bi2O3 shield with 90% silicon and 10% nano Bi2O3 was prepared and dosimetry test was down in radiology by PTW DIADOS E dosimeter.Results: The m...

The broad family of LEA proteins are intrinsically disordered proteins (IDPs) with several potential roles in desiccation tolerance, or anhydrobiosis, one of which is to limit desiccation-induced aggregation of cellular proteins. We show here that this activity, termed molecular shield function, is distinct from that of a classical molecular chaperone, such as HSP70 - while HSP70 reduces aggreg...

Electromagnetic induction imaging has wide potential application in the disciplines of medicine, security, industry, geophysics and scientific research in general. The present study focuses on the applications in the security industry and in particular on providing a new tool for cargo screening in the context of the detection of illicit trafficking of special nuclear materials. The thesis repo...

Abstract Safety of satellites as well spacecrafts during space missions is a primary objective to preserve the physical and virtual assets onboard. Whipple shields belong class protective equipment provided on surface satellites, sustain impacts from ultra-high speed debris, which can otherwise cause considerable damage corresponding structures. Recent works whipple are focussed determining res...

Background: Changes in body composition may be used for monitoring progression/ regression of a disease. Prompt γ-rays in vivo neutron activation analysis (IVNAA) has been widely used for the measurement of body composition in recent years.Objective: In this paper, we tried to improve the safety of IVNAA operator.Methods: The most important factor for reducing the operator receiving dose is th...

BACKGROUND Unlike hemorrhagic injuries in which direct pressure is indicated, any pressure placed on the eye after penetrating trauma can significantly worsen the injury by expulsing intraocular contents. The accepted first response measure for obvious or suspected penetrating ocular injury is placement of a rigid shield that vaults the eye so as to prevent accidental iatrogenic aggravation dur...
