This study was conducted to compare the genotoxic effects of various concentrations of plant oils from Eruca sativa (Brassicaceae), Zingiber officinale (Zingiberaceae) and Origanum majorana (Lamiaceae) to the conventional organophosphate insecticide (Chlorpyrifos) against Rhyzopertha dominica Fabricius. The R. dominica population was reared for several generations without exposure to any insecticide. Wheat grains were sterilized at 55°C for 6h in order to eliminate any hidden infestation, treated with serial dilutions of Chlorpyrifos and plant oil extracts, and subsequently fed to R. dominica for 1, 2, 3, 6 and 8 days. Th...

Study of the effect of gamma-irradiation on the activation energy value from the thermoluminescence glow curve
This study calculates the activation energy value (E) from the thermoluminescence (TL) glow curves using the initial rise method (IR). For non-irradiated samples, the E value is 0.58eV, whereas the irradiated samples have a higher value of 0.84eV. This difference allows us to distinguish between irradiated and non-irradiated chilli powder and to assess the dose of gamma-irradiated samples. (Source: Journal of Taibah University for Science)
