Formation and evolution of defect levels in the electronic structure silicon nitride with cubic spinel structure, γ-Si3N4, after irradiation He+ ions was investigated using spectroscopic techniques. Strong changes cathodoluminescence (CL), photoluminescence (PL), excitation (PLE) Raman spectra were detected. In particular, excitonic PL significantly inhibited a new near-IR band appeared gap hν≥...

The aim of the current study is to examine the protective effect of MGN-3 on overall maintenance of hematopoietic tissue after γ-irradiation. MGN-3 is an arabinoxylan from rice bran that has been shown to be a powerful antioxidant and immune modulator. Swiss albino mice were treated with MGN-3 prior to irradiation and continued to receive MGN-3 for 1 or 4 weeks. Results were compared with mice ...

This study set out to evaluate the microbiological status of rabbit meat and the possibility of using irradiation to control foodborne pathogenic bacteria and extend the refrigerated storage life of meat. Rabbit meat samples were γ irradiated at doses of 0, 1.5 and 3 kGy. The samples were stored at refrigeration temperature, then the effects of irradiation and storage on their microbiological, ...
