The University of Babylon is a university located in Babylon, Iraq. It consists of 20 colleges within three compounds, located seven kilometers south of the city of Hillah, in Babylon Province. The campus was originally the Administrative Institute of Babylon. Later some of the buildings were adopted for use by the medical college of the University of Kufa, before being established as a university in its own right in 1991.The university now teaches a wide variety of subjects, and during the 1990s, started teaching night classes. These became popular, especially among well-off families, after the increase in difficulty of high school examinations in 1997. Wikipedia.

Polycystic ovary syndrome (PCOS) is one of the most common endocrine disorders, which is involved in the multi-system disease, and its etiology is still not clearly understood. It is currently considered that not only the genetic factors but also the environment factors play a crucial role in the pathogenesis of PCOS. Diabetes mellitus (DM)is a term that described a metabolic disorder with heterogeneous etiologies which has been characterizing by chronic hyperglycemia and disturbances of carbohydrate, fat and protein metabolism resulting from defects in insulin secretion, insulin action, or both. There is a complex interaction between obesity, insulin and leptin resistance, and the endocrine abnormalities in PCOS. The aim of this study was to assess the effect of G>A at nucleotide 2548 codon 849 of leptin gene and Q>R at nucleotide 668 codon 223(Gln223Arg) of leptinreceptor gene polymorphisms on serum leptin concentrations in PCOS and DM women patients.This investigate was done by extraction of DNA from whole blood and used PCR-RFLP technique to assess of the different genotypes of LEP and LEPR genes. Leptin concentration was assessed by competitive ELISA method. The present study showed a significant different in leptin levels of GG, QQ genotypes in PCOS patients compared to GA and AA genotypes and the frequency of GG genotypes in LEP and LEPR genes were 57% and 40% compare to controls(37%) and the odd ratios were(0. 443, CI95% 0.2-0.7)(1.15,CI 95% 1.24-3.23), respectively. Conclusion. The GG and QQ genotypes was risk factors to PCOS patients, but not for DM patients. PCOS is associated with leptin levels in women with GG genotypes of LEP gene compared to those with GA and AA genotypes. In both PCOS and DM patients are not associated in LEP concentration in QQ genotypes of LEPR genes compared to QR and RR genotypes. © 2016, Sphinx Knowledge House. All rights reserved.

This research include, photocatalytic decolorization of an aqueous solution of 3 ppm of brilliant cresyl blue in a suspension of 0.11gm/100 ml of ZnO metal oxide semiconductor as a catalyst, was carried out by using 125Watts mercury lamp from external source inside a Pyrex photoreaction cell of 100 ml at room temperature 298 K. The effect of various parameters, such as mass of catalyst, initial dye concentration, and light intensity was studied. The disappearance of original colored dye concentration with irradiation time was monitored by using UV-VIS spectrophotometer. The results indicate that this photoreaction is a pseudo first order reaction according to the Langmuir -Hinshelwood relationship. It has been observed that the increase of light intensity leads to the increase of decolorization rate of brilliant cresyl blue. © 2015, Sphinx Knowledge House. All Right reserved.

In the present paper, the effect of constant magnetic field on natural convection in a semi-circular enclosure that is filled with nanofluids (copper (nanoparticles) with pure water (base fluid)) with present heat flux is investigated numerically. The heat flux (q″) is supplied partly in the center of the base wall, and the other parts of base wall of the enclosure are assumed adiabatic. The center of the circular arc (-45°≤γ≤+45°) is assumed at constant cold temperature (Tc) and the other parts of the circular arc are adiabatic. The gravity (g) acts normal to the y-direction and the uniform external magnetic field (Bo) is applied parallel to gravity. Finite element method based on the variational formulation is employed to solve momentum and energy balance as well as post-processing streamfunctions and heatfunctions. The results are based on visualization of heat flow via temperature lines and heatfunctions, and fluid flow via streamfunctions. Comparisons with previously published work are performed and the results are found to be in good agreement. This paper examines the influence of pertinent parameters such as Rayleigh number (104≤Ra≤107), Hartmann number (0≤Ha≤80 step 20), and solid volume fraction of nanoparticles (0≤φ≤0.15 step 0.05) on the flow, temperature fields and the heat transfer performance of the enclosure.The results show that the heat transfer rate increases with an increase of the Rayleigh number and the nanoparticles volume fraction but it decreases with an increase of the Hartmann number. The effect of the magnetic field on heat transfer increases with the increase of Rayleigh number and it decreases with the increase of the nanoparticles fraction effect. © 2014 Elsevier Ltd.

This paper focused on behavior of beam strengthened with CFRP plate and effect of strengthening length. The simply supported steel beam tested in previous work was modeled using ANSYS finite element software, The same parameters as the experimental data were used to model the steel beam in FEA. Characteristic points on the load-deflection response curve predicted using finite element analysis (FEA) were compared to experimental data. The comparison shows that the ANSYS finite element program is capable of modeling and predicting the actual deformation behavior for steel beam. The FE model simulated in this study used to build continuous steel beam and strengthening it by using different length of CFRP plate as a ratio of beam length. The FE analysis result shows that the length of CFRP plate when reach (40% and 60%) of span length and total beam length in sagging and hogging regions respectively, the increased of ultimate strength of beam become growth slowly. © 2011 Elsevier Ltd.

Purpose: Tonometry, or measurement of intraocular pressure (IOP), is one of the most important examination procedures in ophthalmic clinics, and IOP is an important parameter in the diagnosis of glaucoma. Because there are numerous types of tonometer available, it is important to evaluate the differences in readings between different tonometers. Goldmann applanation tonometers (GATs) and noncontact air-puff tonometers (APTs) are largely available in ophthalmic clinics. The purpose of this study was to evaluate the role of AP tonometer by comparing the measurements of IOP made using this device with those made using a GAT. Patients and methods: This study involved 196 eyes from 98 study participants, all of whom were patients attending an ophthalmic outpatient clinic. Each patient's IOP was measured using both Goldmann applanation tonometry and AP tonometry, and the difference in readings between the two methods was calculated. Results: The mean IOP as measured by GAT was 13.06 ± 4.774 mmHg, while that as measured by AP tonometer was 15.91 ± 6.955 mmHg. The mean difference between the two methods of measurement was 2.72 ± 2.34 mmHg. The readings obtained by AP tonometer were higher than those obtained by GAT in 74% of patients, and this difference was most obvious when the GAT measurement of IOP exceeded 24 mmHg. No statistically significant variation in IOP was noted between the devices when the patients' age, sex, and laterality (right and left eyes) were considered. Conclusion: There is a significant difference in the measurement of IOP between GATs and AP tonometers. Goldmann applanation tonometry remains the most suitable and reliable method for measuring IOP. Because measurements of IOP by AP tonometer are usually higher than those obtained by GAT regardless of the patient's age, sex, or laterality of eyes, AP tonometry is a suitable method for community or mass screenings of IOP. © 2013 Farhood, publisher and licensee Dove Medical Press Ltd.

A finite volume numerical simulation of natural convection in a parallelogrammic air-filled cavity having a heated concentric circular cylinder is performed. The left and right sidewalls of the cavity are maintained at a uniform cold temperature, while both upper and lower walls of it are considered thermally insulated. A wide range of significant parameters such as Rayleigh number, inclination angle and cylinder vertical locations are considered in the present study. Comparison with previously published works is made and found to be an excellent agreement. The results show that the strength of the flow circulation and the thickness of thermal boundary layer around the hot circular cylinder are increased dramatically when the Rayleigh number increases. Also, to increase the flow circulation inside the parallelogrammic cavity, it is recommended to make the inner cylinder moves downward until it reaches to [δ= - 0.2] and the parallelogrammic cavity sidewalls inclined to [Φ = 15°]. Moreover, it is found that for various values of the inclination angle, the average Nusselt numbers at inner cylinder surface and at both cavity sidewalls, decrease when the cylinder moves upward, while they increase when the cylinder moves downward. © 2013.
