In this study, the control method of greater wax moth using male sterilization technique with gamma ray and chemical control methods were examined and compared. In order to determine the safe and effective dosage of gamma-ray to sterilize male pupae of the greater wax moth, an experiment was conducted in a complete randomized design with 5 treatments and 3 replicates with 50 male pupae in each ...

  Interaction of fast neutrons with oxygen atoms of cooling water in reactor core leads to the production of 16N isotope which emits 6.13 MeV gamma ray. A system is developed to measure the 16N gamma ray activity using a5.08cm ×5.08cm NaI(Tl) detector. A suitable electronic system is used to count 16N gamma rays in different reactor powers in order to calibrate the 16N system in terms of reacto...

AE Aquarii (AE Aqr) is a cataclysmic binary hosting one of the fastest rotating (Pspin = 33.08 s) white dwarfs known. Based on seven years of Fermi Large Area Telescope (LAT) Pass 8 data, we report on a deep search for gamma-ray emission from æ. Using X-ray observations from ASCA, XMM-Newton, Chandra, Swift, Suzaku, and NuSTAR, spanning 20 years, we substantially extend and improve the spin eph...
