New applications and developments in the neutron shielding
EPJ Web of Conferences, 2017 Shielding neutrons involve three steps that are slowing neutrons, absorption of neutrons, and impregnation of gamma rays. Neutrons slow down with thermal energy by hydrogen, water, paraffin, plastic. Hydrogenated materials are also very effective for the

Radiation effect on germination and seedling traits in rice (Oryza sativa L.)
Electronic Journal of Plant Breeding, 2019 The biological effect of new source of physical mutagen viz., electron beam over gamma rays were studied with different dosages in the M1 generation of rice during 2017-18.

Gamma-ray luminosity properties of gamma-ray pulsars [PDF]
Astronomy & Astrophysics, 2004 Based on a new self-consistent outer gap model, we statistically study luminosity properties of gamma-ray pulsars with ages of less than or equal to2 x 10(7) yr in the Galaxy as well as those with ages of less than or equal to5 x 10(6) yr in the Gould belt using a Monte Carlo method, where the gamma-ray beaming effect has been included.

Probit analysis and effect of electron beam and gamma rays in blackgram (Vigna mungo (L.) Hepper)
Electronic Journal of Plant Breeding, 2017 An experimental investigation was carried out to determine the lethal dose (LD50) of electron beam and gamma rays on two black gram varieties viz., MDU 1, VBN (Bg) 4. The lethal dose was determined by probit analysis. Dry seeds of both the varieties were

GAMMA-RAY OBSERVATIONS OF GAMMA-RAY BINARIES
International Journal of Modern Physics: Conference Series, 2014 Gamma-ray binaries are binary systems that emit most of their radiative output above 1 MeV. Following the detection of five such systems in the past decade, they have been clearly established as a population of galactic GeV and TeV sources. In this review I discuss their recent gamma-ray observational results from Cherenkov telescopes and the Fermi ...

Particles, Strings and Cosmology (PASCOS 99), 2000 Ultra-high-energy, >10^19 eV, cosmic-ray and high energy, ~10^14 eV, neutrino production in GRBs is discussed in the light of recent GRB and cosmic-ray observations. Emphasis is put on model predictions that can be tested with operating and planned cosmic-ray and neutrino detectors, and on the prospects of testing for neutrino properties.

Nuclear Instruments and Methods in Physics Research Section A: Accelerators, Spectrometers, Detectors and Associated Equipment, 2003 An astrophysics application of a low noise Double-sided Silicon Strip Detector (DSSD) is described. A Semiconductor Multiple-Compton Telescope (SMCT) is being developed to explore the gamma-ray universe in the 0.1-20 MeV energy band. Excellent energy resolution and polarization sensitivity are key features of the SMCT.

Multiwavelength Variability Analysis of 3C 279
Frontiers in Astronomy and Space Sciences, 2017 We present a multifrequency analysis of the variability in the flat-spectrum radio quasar 3C 279 from 2008 to 2014. Our multiwavelength datasets range from 1 mm to gamma-rays, with additional optical polarimetry.

EFFECT OF GAMMA IRRADIATION,METHYL METHANE SULPHONATE AND THEIR COMBINATIONS ON GROWTH, FLOWERING AND INDUCED VARIABILITY IN Tagetes erecta, L. [PDF]
Journal of Plant Production, 2000 Seeds of Tagates erecta. were irradiated with different doses of gamma-rays ( 0,5,10 and 15 kr.), other part of seeds was treated with different levels of MMS ( 0.0, 0.1, 0.2, 0.3,0.4, 0.5 and 1.0%) .

The Gamma‐Ray Observatory [PDF]
Annals of the New York Academy of Sciences, 1989 AbstractThe Gamma-Ray Observatory (GRO), a Shuttle-launched free-flying Observatory is currently scheduled for launch in November 1990. The mission provides nearly six orders of magnitude in spectral coverage, from about 50 KeV to about 30 GeV, with a sensitivity over the entire range over an order of magnitude greater than that of previous ...
