in order to improve the performance of a newly developed radiochromic film, gic-79, somedosimetric characteristics of this film have been studied based on relevant standard practice. the presentstudy describes some parameters that may affect the dosimeter response before, during, and after irradiation. the effect of absorbed dose rate on dosimeter response was determined by irradiating dosimete...

Gamma-ray irradiation as a physical mutagen has high penetrating power. Therefore, it is most often used to increase genetic variability or produce new mutant plants. This research was conducted obtain the lethal dose of gamma-rays in Leersia hexandra The plant part single node stolon which had length 10 cm with middle stolon. doses given were 0, 25, 50, 75, 100 Gy. Stolons inserted into plasti...

Abstract We investigate the prospect of detecting Dark Matter (DM) candidate in three-loop radiative neutrino mass generation model extended with large electroweak multiplets Standard Model (SM) gauge group, at future imaging atmospheric Cherenkov telescope known as Telescope Array (CTA). find that addition such leads to a sizable Sommerfeld enhanced annihilation DM O (TeV) mass, into SM bosons...

background: high density concrete is extensively used for efficient radiation attenuation in radiotherapy rooms and nuclear reactors. over the past eight years, some efficient galena-based concrete samples for shielding x or gamma rays was produced. the goal of this study was to produce a novel high density concrete against neutron and photon radiations using tourmaline and galena. materials an...

Abstract. Nilahayati, Nazimah, Handayani RDS, Syahputra J, Rizky M. 2022. Agronomic diversity of several soybean putative mutant lines resulting from gamma-rays irradiation in M6 generation. Nusantara Bioscience 14: 34-39. Soybean is one the foremost commodities for Indonesian people. Therefore, increasing domestic production absolutely must continue to be pursued. One way that can done use ass...

The blazar 3C 279 emits a flux of gamma-rays that is variable on timescales as short the light-crossing time across event horizon its central black hole. It commonly reported spectral energy distribution (SED) does not show signs pair attenuation due to interactions gamma rays with ambient ultraviolet photons, concluding must originate from substructures in jet outside broad-line region (BLR). ...

To identify Schizosaccharomyces pombe genes involved in recombination repair, we identified seven mutants that were hypersensitive to both methyl methanesulfonate (MMS) and gamma-rays and that contained mutations that caused synthetic lethality when combined with a rad2 mutation. One of the mutants was used to clone the corresponding gene from a genomic library by complementation of the MMS-sen...

Taking into account the recent suggestion that a short gamma-ray burst (GRB) looks like the first 1 sec of a long GRB, we propose that the jet of a GRB consists of multiple sub-jets or sub-shells (i.e., an inhomogeneous jet model). The multiplicity of the sub-jets along a line of sight ns is an important parameter. If ns is large (≫ 1) the event looks like a long GRB, while if ns is small (∼ 1)...

PURPOSE To study the comparative structural and functional changes between wild-type (wt) and N-terminal congenital cataract causing αA-crystallin mutants (R12C, R21L, R49C, and R54C) upon exposure to different dosages of gamma rays. METHODS Alpha A crystallin N-terminal mutants were created with the site-directed mutagenesis method. The recombinantly overexpressed and purified wt and mutant ...
