irradiation is known to inhibit waste in stored garlic. treatment time and optimum irradiation dosage are two key factors in achieving the least waste in this process. these two factors were investigated on white ecotype bulbs from hamedan, iran that were irradiated after harvest for 30 and 45 days using fast electrons at dosages of 0, 25, 50, 75, 100, and 150 gy. different properties of the ga...

Competitiveness of released males in genetic control programmes is of critical importance. In this paper, we explored two scenarios to compensate for the loss of mating competitiveness after pupal stage irradiation in males of the malaria mosquito Anopheles arabiensis. First, competition experiments with a higher ratio of irradiated versus un-irradiated males were performed. Second, pupae were ...

On day 33 of gestation, foetal beagles were irradiated in utero (0.9 Gy of 60Co gamma-irradiation, 0.4 Gy/min). Foetal haematocytopoiesis was studied during the third trimester of gestation (days 42-55). Peripheral blood nucleated cell counts were 33 per cent lower than normal on day 44 and continued to be lower until day 49, when values became higher than normal. Splenic cellularities of irrad...

It is well known that ultraviolet B irradiation leads to dermal inflammation. In this study, we found that Mekabu fucoidan suppressed edema, decreased the thickness of the prickle cell layer, and decreased matrix metalloproteinase 1 in the skin of mice irradiated with ultraviolet B. Moreover, we found that the mean level of interferon gamma of Mekabu fucoidan-treated, ultraviolet B-irradiated m...

Background: Similar to the thermoluminescence (TL) spectra, the optical parameters variations can also be used in TL crystals for dosimetry purposes. These optical parameters can include absorption, transmission and reflection coefficients. Materials and Methods: Single crystals of KBr and KCl which have been used in this research were grown from laboratory grade extra pure precursor p...

Background: Cytotoxic therapy can lead to prolonged azoospermia or even sterility. In the present study, we investigated the morphological changes of mouse testes after gamma-Radiation. Methods: After anaesthetizing of NMRI mice, testes and their surrounding tissues were irradiated using a cobalt therapy machine. Four experimental groups were irradiated with fractionated doses of: 1.5+8, 1.5+1...

A model describing the transport of charge carriers generated in silicon detectors (standard planar float zone and MESA diodes) by ionizing particles is presented. The current pulse response induced by and particles in non-irradiated detectors and detectors irradiated up to fluences 3 10 particles/cm is reproduced through this model: i) by adding a small n-type region 15 m deep on the p side fo...

Specimens from eye and genital tract were cultured in parallel in irradiated and non-irradiated McCoy cells and the frequency of isolation of chlamydia using these culture methods was compared. There was a significant difference between the frequencies of isolation; irradiated McCoy cells produced a greater number of positive results.
