Clomiphene citrate is commonly used to induce ovulation in women. However, the effects of clomiphene citrate on the domestic chikens ovary's have not been fully elucidated. Therefore, we used histological analyses to examine the ovaries of Iraqi domestic chickens administered clomiphene citrate (25 mg/kg of body weight) daily for 30 and 60 days. Our results demonstrated that the ovaries from the hens that were administered clomiphene citrate for 30 and 60 days were not morphologically or histologically distinct. However, compared to the control group, both these groups showed a significant treatment effect on ovarian diameter and the number of follicles (P < 0.05), from the result we can conclusion that the clomophene citrate stimulating the ovalation in domestic chikens .

The study provides a new insight into the impact of Se on green algae Chlorocouyeoccum littorale and effects of Se on antioxidant system and bioaccumulation. Se positively promoted C. littorale growth at lower concentrations (≤50 mg L−1), acting as an antioxidant through the inhibition of lipid peroxidation (LPO) and intracellular reactive oxygen species (ROS). The antioxidative effect was associated with an increase in guaiacol peroxidase (GPX), catalase (CAT), superoxide dismutase (SOD) and photosynthetic pigments. Meanwhile, significant increase in the cell growth rate and organic Se content was also detected in the algae.

This paper presents the test results of an experimental study on shear strength of reinforced concrete T-beams cast using self- compacting concrete (SCC) with recycled concrete aggregate (RCA) as a partial replacement of coarse aggregate. Twenty seven T-beams were cast and tested, the variables were the shear span to effective depth ratio (1, 2 and 3) , the RCA replacement ratio (0% ,50% and 75%) and the amount of web reinforcement. The beams were tested under four-point load condition. During the test, the values of the first crack load and the ultimate load were observed as well as the deformation of the beams. The experimental results indicated that when increasing the RCA replacement ratio to 50%, the first cracking load and the ultimate load reduced by an average of 30% and 6% respectively. When the RCA replacement ratio was 75%, the first cracking load and the ultimate load reduced by 31.6% and 9.4% respectively. It can be observed that, at the load 500kN, T-beams with the higher replacement ratio of RCA exhibited slightly higher deflection. Also the first cracking load and the ultimate load decreased with the increase of (a/d) ratio. The presence of web reinforcement causes an increase of about 16% in cracking load. This increase seems to be independent of a/d ratio and the RCA replacement ratio. The average increase in ultimate loads were 4.4% , 18.9% and 28.4% for a/d ratio of 1, 2 and 3 respectively.The presence of web reinforcement slightly reduced the measured deflection and crack width, and its effect was more for the lower stirrup spacing.

Oil pollution of the soil due to a leakage in oil tubes, transportation of products, or during oil excavations can change the soil physical and mechanical, chemical, and biological properties. Consequently, the soil may or may not be eligible for engineering construction projects and it may need a significant treatment. Therefore, it is required to have a better understanding of the general behavior and the corresponding geotechnical properties upon pollution particularly for those areas associated with oil explorations and industry like Thi-Qar Governorate. Fine and coarse soils from two sites at the University of Thi-Qar are artificially contaminated with oil products ranging from 0% to 10% of their dry weight. Testing programs have been performed on both soils included conventional tests such as grading, Atterberg limit, vane shear and direct shear tests. To achieve a fair comparison, the outcomes are directly compared to those of the original uncontaminated soil. The final results of this study indicated the variations in the soil properties for the studied soils upon contamination and addressed the concept behind such behavior.

This investigation concern to explain the failure operation that connected with wire drawing process. Microstructural examination was carried out for several samples of drawn wires. Copper and aluminum wires were pulled from 8 mm diameter to 3.5 mm for aluminum and to 1.75 mm for copper. The cross-sectional microstructure shows some porosity at the normal drawing condition, while no porosity at the drawing direction surface. The conclusion of this work represents that porosity will be created due to heat results from drawing process, which equal to recrystallization temperature or more, and accumulated porosity will be progressive to the final stage of wire failure.

This work was carried out in the cancer research Thi-Qar University, Iraq. This study demonstrates that a reliable, non-invasive sex determination can be achieved by PCR analysis of maternal serum during the first trimester of pregnancy. In contrary to the risks of invasive methods that affect both mother and fetus, applying cell-free fetal DNA (cffDNA) is proven highly effective with lower risk. One of the applications of prenatal diagnosis is fetal gender determination, which is important in fetuses at risk of sex-linked genetic diseases. In such cases by obtaining the basic information of the gender, necessary time management can be taken in therapeutic to significantly reduce the necessity of applying the invasive methods. The aim of this study was to use simple multiplex PCR protocol of fetal gender at early stage of gestation applying a multiplex PCR amplification of the ATL 1 locus in the FMR1 gene located on the long arm of X-chromosome5 and the Y-chromosome-specific sequence. A total of 52 pregnant women participated in this study, The ATL1 specific sequences were detected in all 52 serum specimens, while the Y-chromosome-specific fragment were generated in 23 of serum samples. The Y-specific fragment was not detected in any of the 29 serum samples of serum.
