    Abstract: From human and animal provenances, antibiotic-resistant microorganisms come into water mediums. Such bacteria are capable of diffusing their genes into water-indigenous microbes, which as well hold resistance genes. Conversely, several antibiotics from industrial sources spread in water mediums, greatly modifying microbial ecosystems. During the la... Show More

    Abstract: The effect of the different ratios of bismuthon Nitrile Butadiene Rubber (NBR)/nano silica composite as shielding materials are studied in this study. And the study was carried on for gamma ray photon energies (0.3, 0.6, 1.25, 3 and 7) MeV obtained by (131Ir, 60Co and 137Cs) radioactive sources by using MCNP5, WINXCOM and Matlab. The numerical simu... Show More
