Chromosomal aberrations and oxidative DNA adduct 8-hydroxy-2-deoxyguanosine as biomarkers of radiotoxicity in radiation workers
Conclusions Scoring of chromosome aberrations such as breaks, fragments and dicentrics is a reliable method to detect previous exposure to ionizing radiation. This type of monitoring may be used as a biological dosimeter instead of physical dosimetry.8-OHdG is a useful oxidative DNA marker among radiation workers and those exposed to environmental carcinogens.

Nutritional optimization for anaerobic growth of Bacillus steaothermophilus LLD-16
In this study, a range of nutritional supplements including twenty amino acids, major vitamins and four nucleic acid bases were exploited as added-value supplements for the growth of a lactate-minus (ldh) mutant Bacillus stearothermophilus LLD-16 under anaerobic environment. The chemostat studies revealed that five amino acids that includes aspartate, glutamate, isoleucine, methionine, and serine were essential for persuaded growth of B. stearothermophilus LLD-16. The anaerobic batch studies showed that a number of nutritional supplements, such as, p-aminobenzoic acid (PABA), folic acid, pantothenic acid, adenine, glycine,...

Publication date: Available online 22 December 2015 Source:Journal of Radiation Research and Applied Sciences Author(s): Ahmed H. Orabi, Enass M. El-Sheikh, Wafaa H. Saleh, Ahmed O. Youssef, Mohammed Y. El-Kady, Zeinab M. Shalaby The prepared amine-impregnated cellulose (AIC) was found to be an efficient adsorbent for uranium originated from El-Sebaiya phosphate ore. The impregenation process was carried out by copolymerization between pretreated cellulose and a mixture of (tri-ethyl amine and epi-chorohydrine). In the present work, two working solutions were used. The first solution was a synthesized phosp...

Electron beam and gamma ray irradiated polymer electrolyte films: Dielectric properties
In this study, polymer electrolyte films were irradiated with electron beam (EB) and Gamma ray (GR) at 50 and 150 kGy. The induced chemical change in films due to irradiations have been confirmed from the Fourier Transform Infra red (FT-IR) spectra. The X-ray Diffractometry (XRD) results show that crystallinity decreases by ∼20% in EB and ∼10% in GR irradiated films respectively. The micro structural arrangement was investigated by Scanning Electronic Microscopy (SEM) and the images reveal that there is a substantial improvement in the surface morphology in irradiated films. The real (ε′) and imaginary (ε″) diel...

Variability of Fresnel surface emissivity of Persian Gulf water in a nadir-viewing direction at C- band
In this study, the variability of vertical and horizontal polarizations of Fresnel emissivity over the Persian Gulf water at 5 GHz in a nadir-viewing direction are investigated by using Fresnel's equations. Data sets used to compute Fresnel reflection coefficients were provided from our previous studies on hydrodynamic and electromagnetic properties of Persian Gulf water. The calculations indicated that spatial variability of Fresnel emissivity for both vertical and horizontal polarizations were relatively large compared to its temporal variability. The annual domain-averaged mean for vertical emissivity at the C- band wa...
