genetic diversity amongst 21 induced mutant clones tolerant to salinity along with one non-irradiated sensitive clone of banana (musa acuminata cv. dwarf cavendish (aaa)) were studied using morphological and random amplified polymorphic dna (rapd) markers. out of the 30 phenotypic indices screened, 23 were polymorph and two traits, leaf habit and blotches color, were differentiated by non-irrad...

the aim of this study was to determine feasibility of gamma irradiation in broiler chicks’ diet and scrutiny of productive performance of broiler due to gamma irradiated diets. there were 256 broiler chicks (male and female) from arian strain. experiment was statistically analyzed using balanced complete randomized design with four factors (including four irradiation doses: 0, 6.7, 7.7 and 8.7 ...

We have modeled irradiated planets located near a dM5 and a G2 primary star. The impinging radiation field was explicitly included in the solution of the radiative transfer equation and in the computation of the atmospheric structure. We find that large errors in both the thermal and reflected flux will result from models which do not include the impinging radiation in a self-consistent manner....

The technology of food irradiation is gaining more attention around the world. This method recognized by using ionising radiation in order to control foodborne pathogens, reduce microbial load and insect infestation, inhibit germination root crops, extend durable life perishable produce, plant-derived allergens. According International Atomic Energy Agency (IAEA), than 50 countries have approve...

Irradiated ground beef samples (ca. 3-g portions with ca. 25% fat) inoculated with Yersina pestis strain KIM5 (ca. 6.7 log CFU/g) were heated in a circulating water bath stabilized at 48.9, 50, 52.5, 55, 57.5, or 60 degrees C (120, 122, 126.5, 131, 135.5, and 140 degrees F, respectively). Average D-values were 192.17, 34.38, 17.11, 3.87, 1.32, and 0.56 min, respectively, with a corresponding z-...

BACKGROUND Vascular abnormalities are a major cause of postoperative complications in irradiated tissues. Endothelial cell dysfunction characterized by diminished endothelium-dependent relaxation may be involved. We examined the endothelium-dependent relaxation and morphology of the endothelium in irradiated human cervical arteries. METHODS AND RESULTS Irradiated arteries were taken from the ...

The purpose of this study was to investigate the influence of electron beam (EB) irradiation on the structure and physical properties of Nafion 117 membranes (in both acid and sodium forms) when they are irradiated in water and isopropanol as solvents. The mechanical properties of Nafion membranes in acid form irradiated in water were found to rapidly deteriorate as the irradiation dose was inc...

the radiation-induced bystander effect is the phenomenon which non-irradiated cells exhibit effects along with their different levels as a result of signals received from nearby irradiated cells. responses of non-irradiated cells may include changes in process of translation, gene expression, cell proliferation, apoptosis and cells death. these changes are confirmed by results of some in-vivo s...

Escherichia coli MC1061 cells were irradiated at 660 and 900 nm, incubated in M9 and LB media with the use of a specially constructed device, and assayed for growth rate. There was a reduction of growth rate stimulation when the irradiated culture was cultivated jointly with the non-irradiated one. In the same time, the irradiated culture extended the invigorate effect on the non-irradiated one...
