The Fermi Gamma-ray Space Telescope has revolutionized our knowledge of the gamma-ray pulsar population, leading to the discovery of almost 100 gamma-ray pulsars and dozens of gamma-ray millisecond pulsars (MSPs). Although the outer-gap model predicts different sites of emission for the radio and gamma-ray pulsars, until now all of the known gamma-ray MSPs have been visible in the radio. Here w...

The soybean (Glycine max l. merr) is one of oil seed plants from leguminous family. In this study, the effect of gamma radiation on chlorophyll, soluble and insoluble carbohydrate and composition oil seeds were investigated in soybean. Soybean variety J.K was irradiated with 0,100,200 and 300 gamma ray. The treatment and control seeds planed in with four replicates. The highest amount of total ...
