Advanced radiation applications have been widely used and extended to many fields. As a result of this fact, choosing an appropriate shielding material based on the application has become vital. In regard, integration elements into polymer composites investigated contributed quantity quality materials. This study reports photon attenuation parameters electromagnetic effectiveness novel composit...

The microbiological contamination of raw plant materials is common and may be adequately reduced by radiation processing. This study evaluated the effects of gamma- and e-beam ionizing radiations (25 kGy) on three plants used as food or as medicinal products (Thymus vulgaris L., Eucalyptus radiata D.C., and Lavandula angustifolia Mill.) as well as their effects on extracted or commercial essent...

divides into the Lorisiform lemurs and the Lemuriform lemurs. There is some justification for this, yet the unique features of the Malagasy (Lemuriform) lemurs does argue that the nocturnal lorises of Asia and Africa are better kept in a separate category. But here we go arguing terminology, a deplorably bad habit which Sir Wilfred has noted is a characteristic trait of students of the Primates...

On x-irradiation of the eggs and sperm of Arbacia punctulata there was inhibition of respiration with relatively large doses, whereas there was an increase with small doses. The dose required to produce an increase of respiration depended on the degree of sensitivity of the cell to the effect of ionizing radiation. Sperm cells were more sensitive; then came fertilized eggs; unfertilized eggs we...

Bacteriophage T1 was suspended in distilled water and in phosphate buffer, saturated with oxygen, nitrogen, hydrogen, and carbon monoxide, and irradiated with gamma rays and x-rays. Under the same conditions phage was exposed to hydrogen peroxide. Oxygen acted as a protective agent against both irradiation and hydrogen peroxide inactivation. As a protective agent against irradiation, oxygen was...

The incidence of gastric adenocarcinoma in animals is extremely low (13,14), and attempts to produce such tumors with various carcinogenic agents (11), including ionizing radiations (8), have been only moderately successful, at best. The present report deals with a number of malignant and premalignant lesions of the glandu lar stomach of the mouse occurring after wholebody irradiation with x-ra...
