Experimental investigation of the thermal performance of wet cooling tower with splash fills packing
...Show More Authors

With the increasing intensity of the ecological and environmental problems and the scarcity of fresh water, this paper was introduced to investigate the ability to use treated wastewater as a cooling media via studying its behavior throughout a cooling tower. The simultaneous transfer of heat and mass from the treated wastewater to air over splash-fill packing arranged in a zigzag manner was studied. The characteristic of the cooling tower, the outlet water temperature, and the rejected heat were investigated as the water-to-air ratio and inlet water temperature were varied. The core results show that the cooling tower of the tower decreases with increasing water-to-air ratio, and increases with the raise of inlet water temperature. Moreover, relationships between cooling tower and water-to-air ratio were obtained for each. It was also observed that the outlet water temperature increases gradually with increasing water-to-air ratio and temperature, and the difference between the inlet and outlet temperature becomes larger by increasing the inlet temperature. The heat rejected value increases with increasing the air-flow rate, water flow rate, and temperature. This study revealed that cooling tower of splash fills arranged in a zigzag manner was higher compared to other types of packing. In the same time, the results for the treated wastewater and fresh water were very close that gives approximate behavior, and this can save a huge amount of fresh water for other humanistic utilization, along with taking benefit from the treatment process of wastewater instead of through it into the aquatic systems.

Detection of Carbonic Anhydrase Enzyme in Sulcus Median in Hind Brain (Fourth Ventricle) in the Hind Brain of the Adult White Rat (Rutts rutts
...Show More Authors

The method of heavy metals deposition which is based on cobalt in detection of Carbonic anhydrase enzyme in the Sulcus median in the hid brain (fourth ventricle) in the adult white rat (Rutts rutts). An essential amended in the method has been done by using cobalt chloride (CoCl2) instead of cobalt phosphate (Co3(PO4)2) in the reaction medium. Any efficacy of enzymic histochemical for carbonic anhydrase enzyme did not show in histological sections. The floor of the fourth ventricle of the brain is specific, clearly any histochemical reaction sediments have not been found in sulcus median of the floor of the fourth ventricle. The corresponding stain to green methyl which was observed clearly in sulcus median region. The ventral surface of

Influence of the high mobility group A1 genetic polymorphism on indices of metabolic syndrome and insulin resistance in the Iraqi population: Case-control study
...Show More Authors

The high mobility group A1 gene (HMGA1) rs139876191 variant has been related to metabolic syndrome and type 2 diabetes, but data are lacking in Middle Eastern populations. The study aimed to assess whether the HMGA1 rs139876191 variant is associated with metabolic syndrome risk and whether this variant predicts the risk of insulin resistance. This case-control study was carried out at single center in Kirkuk city/ Iraq from February to August 2022. Polymorphisms in HMGA1 and genotyping were identified by Sanger sequencing of genomic DNA obtained from 91 Iraqi participants (61 patients with metabolic syndrome and 30 control). Lipid profile, serum (glucose and insulin), glycated hemoglobin, blood pressure, body mass index, and waist circumfer
