[en] Adult laboratory moths (less than 24 hours) of the cotton leaf worm, Spodoptera littoralis were irradiated with 20, 35 and 50 krad and added to untreated laboratory population. The results on competitiveness of males or females indicated that significant reduction in egg hatch occurred with all combinations as compared with the untreated control. The reduction in egg hatch of the 5:1:1 treatment was more significant than that of the 1:1:1. The competitiveness values were significantly higher for the males or the females irradiated with 20 and 35 krad than for those irradiated with 50 krad. The results of mating competitiveness of irradiated laboratory males of S. littoralis against native moths, indicated a significant reduction in egg hatch within the tested combination as compared with the untreated control (native male X native female). Irradiation of laboratory males with substerilizing doses of 20 and 35 krad lead to good competitiveness with the native males, in mating with native females

[en] Skin cancer is an intimidating disease which necessitates the presence of a non-invasive treatment. Laser-induced thermo therapy is one of the recent noninvasive modalities of superficial lesion treatment. Although of its promising effect, this method still needs more effort to be quantized. Many studies are being conducted for this purpose. Modeling and simulating the process of skin lesion treatment by laser can lead to the best quantization of the treatment protocol. In this paper, we provide finite element models for the treatment of skin cancer using laser thermal effect. A comparison between the effects of using different laser parameters of diode laser (800nm) and Nd: Yag laser (1064 nm) revealed that Nd: Yag laser can be used effectively foe skin cancer treatment specially with high intensities of about 106 w/m².
