Rate constants and thermodynamic studies have been performed on the decay of threonine amino acid peroxides produced from γ- irradiation of aqueous oxygenated solutions at different pH's. The decay was found to follow first order kinetic.
The rate of decomposition increases by increasing temperature and pH of irradiated solutions. The activation thermodynamic measurements illustrate that, the decay of threonine amino acid peroxides is not spontaneously, and thus, it can be concluded that, the temperature here has important effect on post irradiation in this system. Significant change in values of ∆H*, ∆G* and specially ∆S* were observed depending on pH of irradiated solutions. On the view of the obtained results, a proper mechanism for decomposition was suggested.

The protective effect of selenium chloride (SeCl2) against cadmium chloride (CdCl2), induced toxicity on sperms parameters, testes architecture and antioxidant enzymes in male Swiss mice was investigated. Intraperitoneal injection of CdCl2 (0.15 mg) dose in mice reduced total sperm count and significantly associated with increased sperm abnormality and death sperm percentage when compared with controls. The effect of Cd-treated mice showed a significant decrease in weight of testes and epididymides as compared with control groups. The degree of organ weight loss (testes and epididymides) were less severe in long-term treatment. Long-term exposure of both cadmium-injected mice had similar effect as acute exposure but with lower efficacy. Recovery period showed restoring effects in both exposure periods. The histopathological testes changes indicated by the reduction of seminiferous tubule diameter and testes architecture appearance due to the epithelial sloughing and elimination of germ cells were more pronounced at 72h/ Cd treatment. Substantially proves the ongoing damage effect of cadmium on developing germ cells. Long-term exposure of a batch of cadmium –injected mice had a similar effect as acute exposure but with lower efficacy. In addition, Intraperitoneal injection of CdCl2 (0.15 mg) also stimulate lipid peroxidation in testicular tissues, indicated by significant decrease in antioxidant enzymatic activity such as peroxidase and catalase in the experimental mice group.
Administration of SeCl2 in combination with equal volume CdCl2 at the above mentioned doses led to partially organs weight resorted, elevated sperm count and reduction in the percentage of abnormal and dead sperm population along with significant increase in antioxidant enzymatic activities. The protective action and the antagonistic effect of Se at different periods against cadmium –induce toxicity are discussed.

In this work, a computer program has been built to simulate some important X-ray parameters via Thomson scattering. X-ray energy dependence on the emitting and x-ray scattering angles for different incident electron energies were obtained. From this simulation, the X-ray energy was found to be distributed around (-1o to +1o) for X-ray emitting angle. Also it was found that, the X-ray peak energy was increased by increasing the scattering angles. An effort had been made on the angular frequency shift dependence on the scattering angle and laser photon energy. It had shown that the angular frequency shift was more dependent on laser photon energy rather than the scattering angle.

This study was conducted to explore the comparative development of the eye lens in two species of ovoviviparous teleost fish. The first fish was Gambusia affinis while the second was Xiphophorus maculatus.
The results showed that the lens development starts at early stages of development.In both species. The first signal of lens genesis appears at the2nd stage of development, which is seen as spherical solid lens placode in the 1st one fish while in the 2nd fish as irregularly outlined and the radius is less than that of the 1st fish. At the 3rd stage the begining of primary lens fibers synthesis appears at the center of the lens placode in the 1st fish,while in the 2nd one doesn’t appear. On the other hand the genesis of the primary fibers appeared in a parallel pattern in the 2nd fish at the 4th stage. At the 5th stage the initiation of lens capsule was shown at the periphery in the 1st fish and secondary lens fibers primordium appeared in 2nd fish. At the 6th stage the following features are seen: progression of primary and secondary lens fibers, straight sutures between the lens fibers in the 1st fish,and the completion of central lens fibers which appeared parallel with straight sutures,as well as thin of lens capsule in the 2nd fish. At the 7th stage in the 1st fish, the spaces between the lens fibers reduced,the Y shaped suture appeared, while in the 2nd fish, the peripheral lens fibers and their lucident spaces were clear and some of it appeared elongated while the other are circled. On the other hand the primary and secondary lens fibers (straigt and circled), the lens epithelium, the lens sutures in the 2nd fish were completed. The 8th stage considered as the final stage of lens development in both species.The lens componens vary some what between the two adult species. In the adult 1st fish the lens was spherical in shape and its components represented as the capsule, subcapsular epithelium and concentric lens fibers, while in the 2nd adult fish the lens was ovoid in shape, the radius is less that of the 1st fish. The complete differentiation of the primary components were completed at the9th stage of development in the 2nd fish.

In this research, Two methods are used: Partial Least Squares Regression (PLSR) and Principal Components Regression (PCR) to build a model for autoclave cement on factors influnce on it. The comparison between these two methods is done by using two components for the PLSR and PCR, the plot of the fitted data shows that Partial Least Squares Regression represente the data better than Principal Components Regression, and R2 insures this result which is showen by the figure. After that, 10 variables are used to compare these methods, this comparison indicates that the two methods represente the data in the same way. The goal is inreducing the number of components used in the two methods to avoid Over- Fitting, then it is depended on cross- validation method, this method indicates that Partial Least Squares Regression method is more economic than Principal Components Regression.
