Spectrochemical study the effect of high energetic ionization radiation on Ru(III), Pd(II) and Hg(II) complexes
Publication date: Available online 14 March 2017 Source:Journal of Radiation Research and Applied Sciences Author(s): Samar A. Aly Complexes of Ru(III), Pd(II) and Hg(II) of hydrazone ligand have been prepared and characterized by 1H NMR, IR, elemental analyses, electronic spectra, magnetic moment, molar conductance and thermal analysis(DTA/TGA) before and after γ-irradiation. The result of 1H NMR before and after γ-irradiation confirms that the intensity of the peaks after γ-irradiation is larger than before γ-irradiation. Meanwhile, results of infrared spectra proved that γ-ray enhanced the stability of irradiate...

Multi-parameter optimization of a (3He-252Cf-3He) neutron backscattering sensor for landmine detection
Publication date: Available online 23 February 2017 Source:Journal of Radiation Research and Applied Sciences Author(s): Nassreldeen A.A. Elsheikh Experimental measurements were carried out to optimize the performance of a (3He-252Cf-3He) assembly for plastic anti-personnel landmine detection in dry soils. This is done by employing a 252Cf source producing 0.7 × 104 n.s−1 and a pair of two identical 3He detectors. The Signal-to-background ratio due to the responses of the two 3He detectors is monitored and analyzed as a function of detector-detector distance, stand-off distance, mine depth and source position while...

Potential effects of gamma irradiation on the stability and therapeutic activity of anticancer drug, doxorubicin
In this study, the effect of gamma irradiation on the stability and therapeutic activity of one anticancer drug (Doxorubicin) was studied. For this purpose, doxorubicin drug characterized by two methods, at first, in-vitro study, before and after drug irradiation with different doses of gamma rays (2, 5, 20, 100 GY) which achieved through measuring the dielectric relaxation and absorption spectrum of drug solution. Secondly, in-vivo studies, where the unirradiated and the drug, which later exposed to gamma rays, were injected respectively into 6 groups of mice (3 mice in each group). The dielectric relaxation and absorptio...

Microwave irradiation effects on vermicasts potency, and plant growth and antioxidant activity in seedlings of Chinese cabbage (Brassica rapa subsp. pekinensis)
This study investigated MWI effects on vermicasts potency, plant growth and biochemical activity in Chinese cabbage ‘Bilko’ seedlings. Fresh, moist vermicasts were microwaved at power output levels: 0, 100, 200, 300, 400 and 800 Watts (W). Water loss, nutrients and total aerobic plate content were assessed. A complete randomized design greenhouse experiment was used to evaluate seedlings growth performance and tissue bioactivity. Water loss increased from 5 mg/g (0 W) to 215 mg/g (800 W). Total dissolved solids and electrical conductivity of the vermicasts gradually increased with an increase in MWI power output le...

Chemical quality and nutrient composition of strawberry fruits treated by γ-irradiation
This study evaluates the effect of gamma irradiation doses (0, 300, 600 and 900 Gy) on quality parameters and phytochemical content of strawberry fruits during storage periods at 10 °C. The data revealed the irradiation significantly reduced the fruits weight loss and decay rate at storage periods; in comparison with control (unirradiated sample) which gave the maximum value of these quality parameters. Neither radiation treatment nor storage period had significant effect on titratable acidity and pH of fruits. All treatments decreased vitamin C levels during storage but the anthocyanin contents increased gradually duri...
