Gamma-ray bursts are now known to be a cosmological population of objects, which are often accompanied by X-ray and optical afterglows. The total energy emitted in the afterglow can be similar to the energy radiated in the gamma-ray burst itself. If a galaxy containing a large column density of dust is near the line of sight to a gamma-ray burst, small-angle scattering of the X-rays due to diff...

Abstract Plant mutation breeding plays a pivotal role in increasing plant genetic variability, pest and disease resistance yield production. Gamma ray irradiation induced to infected plants obtain resistant mutant plants. This research aims examine the morphological characterization of pepper produced from irradiated PepYLCV-infecting local Karo Regency, Sumatra Utara, Indonesia. The was conduc...

Background: This cross sectional study was conducted to evaluate the effect of &gamma-rays and electron-beam irradiation with a commercial toxin binder-milbond-TX on the performance, feed components, and meat quality of Japanese quails challenged with aflatoxin B1. Methods: Overall, 168 One-d-old chicks (Japanese quails) were allocated to eight treatments with three replicates based on a com...

to evaluate the effect of gamma rays on the seeds and amounts of nitrogen on growth and yield of chamomile (chamomilla recutita synonym matricaria chamomilla), a factorial experiment was conducted based on randomized complete block design with three replications at the research farm of agriculture college of shahid-beheshti.-urmia in 2010. treatments were gamma rays from cobalt-60 on chamomile ...

To identify the specificity of base substitutions, a novel experimental system was established based on rifampicinresistant (Rif) mutant screening and sequencing of the defined region of the rpoB gene in E. coli. We focused on comparing mutational spectra of base substitutions induced by either low energy nitrogen ion beam implantation or Co-gamma rays. The most significant difference in the fr...

Background: The present germplasm of cluster bean lack the needed natural variability for developing early maturing short statured lines. Therefore, an attempt was made to study magnitude heritable stimulated through induced mutation in M3 generation. Methods: generation seeds variety MDU1 treated with gamma rays, electron beam and combination ray EMS were used investigation. biometric observat...
