الوصف: The study discussed the change in rainfall amounts in two governorates of Iraq, one in the north and the other in the south, differing in topographic elevation, The descriptive analytical approach, drawing inferential maps, and adopting a digital elevation model were used to prove the results. The study aimed to clarify the effect of the erosion factor on the increase and decrease in rainfall The decrease in sea level in the two study areas emerges the importance of using the DEM model as an analysis tool in building three-dimensional models of terrain phenomena to give a comprehensive survey of the Earth’s surface, and this in turn enhances the accuracy of the extracted results. The most important results are that the areas most abundant in rain have rains of more than 360 mm corresponds to the highest terrain, which reaches a height of 1800 meters above sea level, represented in the areas of the Aqrah Sinjar Makhmur Mountains within Nineveh Governorate. We find in the second study area, Basra Governorate, that the highest areas are located within the desert range of the Western Plateau and Wadi Hafar Al-Batin, approximately 290 meters, which is sandy land, so that the originality of the scientific fact is revealed in the study, which is the decrease in rain values in areas where the total amount of rain does not exceed 182 mm, as the abnormality of the precipitation system became clear in it, as we find low-lying areas exposed to more rain than areas that are penetrated by a high contour line due to the rock formation. And its limestone, which is located within the desert tongue of the Iraqi Western Plateau region, adjacent to the states of Kuwait and Saudi Arabia, and the scientific value comes from the results obtained in showing the importance of the difference in the factor of erosion in (two governorates) of Mosul, which has a mountainous nature, and the high erosion and surface features in the Basra Governorate, which has low land, and the role of modern technologies, To highlight the effect on the difference in rainfall rates in both

الوصف: Amount of pollution radiation in foodstuffs and feedstuffs are very necessary to measure because it is a direct contact with human and animal health. Therefore, the present investigation is useful for the health and environmental data base. The study included measurement of effective radium-226 content (CRa) in some chosen samples of vegetables and fruits (local and imported) in Najaf governorate. The CRa were measured in samples of vegetables and fruits using Solid State Nuclear Track Detectors (LR-115 Type II). Also, the annual effective dose (AED) associated with the exposure due to annual intake of 226Ra were calculated from ingestion of vegetables and fruits samples for adults. The results were revealed that the average value of CRa in vegetables and fruits samples in the present study was 3.98±1.08 Bq/kg and 1.73±0.11 Bq/kg, respectively. While, the average of AED (mSv/y) for vegetables and fruits samples was 0.067±0.018 and 0.082±0.005, respectively. Also, the results showed that the average value of AED from fruits consumption is larger than in vegetables, but the result is not significant. All results of the CRa and AED of the studied samples had been compared with the worldwide reported value (median). Accordingly, it was found that all findings were lower than that of the recommended limits of the UNSCEAR 2000. Finally, based on present investigations, no health risk expected when considering eating vegetables and fruits of Al-Najaf of Iraq. © 2022. Online Journal of Animal and Feed Research.

الوصف: Drying and rewetting events of soil represents a common physiological stress for soil microbial communities. We investigated the effect of alternate drying-rewetting cycles on N2O emissions and soil microbial communities in jar experiments with soil samples. The results showed that instant flooding and air-drying moments are two important steps of soil drying and rewetting periods influencing soil microbial communities and N2O emissions. N2O fluxes in the air dry (AD) steps were always higher than those in the instant flooding (IF) steps, especially in the early stages of AD and IF. The soil treated with long-term organic matter and chemical fertilizer promoted N2O emissions but inhibited the N2O release from newly applied urea when soil went through drying and rewetting events. Soil moisture content(s) also significantly affected the growth of ammonia oxidiser and denitrifier communities, with the functional gene abundance increasing with increasing soil moisture content. While comparing first and second cycles, N2O fluxes were six times higher in the first cycle than in the second cycle. It is concluded that sudden changes in moisture condition influenced the N2O flux, and nitrifier and denitrifier functional genes by affecting the growth of ammonia oxidiser and denitrifier communities.
