This study aimed to investigate the effect of water treated with a magnetic field with different induction on the histological structure of the kidney and testicular tissue of albino rats. For this purpose, fifty albino rats were divided into five equal groups, the first of which was used as a control group, drank clean tap water for four weeks, the other groups were given daily water treated with a magnetic field with an induction of 500, 1000, 1500 and 2000 gauss. Then the animals were sacrificed and histological changes in the kidneys and testicles were examined. Histopathological examination of the kidneys of animals that were given water treated with a magnetic field with an induction of 500, 1000 and 1500 gauss revealed normal renal tubules and glomeruli. Histopathological examination of the kidneys of rats that consumed water treated with a magnetic field with an induction of 2000 gauss showed numerous focal hemorrhages and vacuolar degeneration of the epithelium lining the tubules. Histological sections at magnification revealed vacuolar degeneration of the epithelium of the tubules, mainly the collecting tubules, the formation of tubular casts and tubular necrosis. Examination of the testicular tissue of rats exposed to water treated with a magnetic field with an induction of 500 and 1000 gauss showed normal seminiferous structure and cytoarchitecture of the germinal epithelium areas, as well as normal interstitial tissue. In contrast, rats given water treated with a magnetic field with an induction of 1500 gauss showed marked narrowing of the seminiferous tubules, moderate vacuolar degeneration of the germinal epithelium, necrosis of a number of spermatogonia cells, and thickening of the testicular interstitium. Histopathological examination of the testes of rats exposed to water treated with a magnetic field with an induction of 2000 gauss showed significant vacuolar degeneration, necrosis of a number of spermatogonia cells, and thickening of the testicular interstitium, as well as significant damage to the seminiferous tubules and germinal epithelium. Thus, water treated with a magnetic field with an induction of 2000 gauss negatively affected both the kidneys and testicles, while water treated with a magnetic field with strength of 1000 gauss improved the function of the kidney and testicular tissue of rats and did not affect their structure
The current research aims to identify the " impact of strategic warheads numbered ( NHT) in the collection average second grade students in the article of history). " To achieve this, I assumed the researcher that there is no different between the statistically significant the average score for the collection of experimental group who teaches the Arab Islamic history on and a strategic warheads numbered and the average score for the collection of the control group who were studying the same article according to the classic method ( traditional) . The study sample consisted of 64 students from the second grade average in the secondary warka bin nawfal in the general Directorate for education first karkh in Baghdad for the annual cources 2

Metal nanoparticles can serve as an efficient nano-heat source with confinement photothermal effects. Thermo-plasmonic technology allows researchers to control the temperature at a nanoscale due to the possibility of precise light propagation. The response of opto-thermal generation of single gold-silica core-shell nanoparticle immersed in water and Poly-vinylpyrrolidone surrounding media is theoretically investigated. Two lasers (CW and fs pulses) at the plasmonic resonance (532 nm) are utilized. For this purpose, finite element method is used via COMSOL multiphysics to find a numerical computation of absorption cross section for the proposed core –shell NP in different media. Thermo-plasmonic response for both lasers is studied. The
... Show MoreSediment samples were collected from main water processing and supply plants in Baghdad, and tested for radioactivity from both natural and artificial sources. These stations are: East Dijla (Tigris), Al-Kadisia, Al-Karama, Al-Rasheed, Al-Sader, Al-Wathba, and Al-Wihda supply stations. Qualitative measurements were made, and the results showed that most sediments exhibited natural radioactive level and sometimes less than the international regular standards. Specially, K-40 and Ra-226 results were much less than the standards for radioactive concentrations. Ac-228 concentration was found rather than Th-232 (in Al-Sader and Al-Wihda samples) but with low concentrations of about 10-15 Bg/kg and detection confidence ~45% , and Ce-141 and Be

The problem of research was the weak ability of most business organizations to employ the strategy of empowerment in maximizing the performance of employees, and the importance of research in practice lies in the results of a guide to managers in how to use the strategy of empowerment in maximizing the performance of employees by mediating organizational trust dimensions of ability, benevolence, integrity. In order to achieve the objectives of the research and to answer the questions of the problem, the researcher has adopted the descriptive analytical approach as the questionnaire was
