This research involves the study of permeability declination as a result of kaolinite due to the changing in pH in the Zubair reservoir (Lower Cretaceous) during the secondary production by water injection method. Four wells and six core samples within the North Rumaila field are studied, Minerals have been diagnosed by XRD and this specific site of clay minerals was diagnosed within the core samples by scanning electron microscopy (SEM). The core samples are also studied petrogrphically using the polarizing microscope and found that they mainly consist of quartz, while the predominant clay is kaolinite. The effect of pH on the values of permeability was examined through a series of laboratory experiments, as it has been tested in the cases of gradual sudden increase form acidic to alkaline. Petrophysical properties (porosity and initial permeability) were measured a prior to testing. After performing these tests, the final permeability was also measured as well as the rate of formation damage. The final permeability decreased gradually at a rate of 20-30% M Darcy during the injection out with solution of pH 3 to 11 with getting formation damage up to 25%. While in the case injection with sudden increase pH from acid to alkaline directly, there has been a rapid and substantial reduction in the final permeability as average of 28% -72%, with a formation damaged rate of 44%. The results confirmed that the reason of the decrease in the permeability is due to the kaolinite mineral which is subject to the dispersion phenomenon during the change in pH, and the acidic environment is suitable for the reservoir, and does not lead to a reduction in permeability.
In this work, we find the terms of the complex of characteristic zero in the case of the skew-shape (8,6, 3)/(u,1), where u = 1 and 2. We also study this complex as a diagram by using the mapping Cone and other concepts.

The Child's theatre was and still is the most investing art for masks of all kinds (partial and total) for suspense, aesthetic and artistic purposes that meet the requirements of those performances. Here the actor's performance is associated with two tools, i.e. the body and the mask, where it has become a must to search for the performance transformations required in order to achieve the highest level of the right performance through this dualism. This urged the researcher to address this problem. Thus, the researcher has put forward an objective to identify the transformations of the character's performance between the body and the mask in the child's theatre shows. The research consists of a methodological framework and a theoretical

Background: Type I diabetes mellitus is an autoimmune disorder characterized by destruction of insuline producing.
Background: Polycystic ovary syndrome (PCOS) women's most prevalent endocrinology condition is a mixture of environmentally and genetically adduced causing PCOS. The relationship between monosaccharide and PCOS is largely unknown.
Objective: This research was designed to investigate the relationship between blood levels of fructose, insulin resistance, and androgen hormone in women with PCOS, and the effect of obesity on the obtained result, as well as to study the efficacy of serum fructose as a biomarker in the diagnosis of PCOS.
Cases and methods: This case-control research study was conducted at the Gynecology Clinic and Infertility Center, in Baghdad Teaching Hospital

The objective of this research is to select the most suitable drilling location of new groundwater exploration wells, with a decision-making tool from Geographic Information System (GIS). The optimum location will be evaluated base on the hydro-geoelectrical parameter derived from Vertical Electrical Sound (VES) including Longitudinal Conductance, the thickness of the aquifer, the apparent resistivity and Transmissivity. From the Geo-electrical method (VES) the finds shows that the aquifers in the study area have Apparent Resistivity ranging from 0.32 to 40.24 Ωm, Thickness between 0.21 m to 15.06 m, Longitudinal Conductance ranging from 0.006 to 10.246Ω-1 and Transmissivity ranging from 0.14 to

Background: Inhibitor development and HCV are considered the most serious complications of hemophilia treatment. Many factors may increase the risk of complications which include: type of hemophilia, age of the patient, age of onset, duration of the disease, & number of replacement per month. Patients and methods: A descriptive study included 200 patients less than 20 years of age admitted to the Hemophilia Center in Children Welfare Teaching Hospital , medical city in Baghdad , their data ( ag , sex , disease onset and duration , severity of hemophilia ) were collected over 8 months period from 1st January to 31st August 2006. Mixing tests and serology tests for HCV and HBV were performed for all patien

The purpose of this paper is to build a simulation model by using HEC-RAS software to simulate the reality of water movement in the main river of Basra City (South of Iraq) which is known as Siraji-Khoura River. The main objective of the simulation is to detect areas where the water cycle is interrupted in some stations of the river stream, as this river has become an outlet for the disposal of sewage, leading to pollution and causing weakness in some sections of the river & obstructing the water cycle that takes place between this river and Shatt al – Arab river. A field survey data of the river and its banks were adopted to derive the grades, longitudinal and cross sections of the river, these data included three-dimensional coordinates

Background: Several studies linked the development of steroid-resistant nephrotic syndrome (SRNS) to genetic variations in the multidrug resistance 1 (MDR1) gene, though a disparity in findings was underlined among children with different ethnic origins. Objective: This study examined the relationship between MDR1 variants (rs2032582 and rs2032583) and the risk of developing SRNS in Iraqi patients with idiopathic nephrotic syndrome (INS). Methods: This case-control study included children with steroid-sensitive INS (SSNS; n=30) and SRNS (n=30) from the Babylon Hospital for Maternity and Pediatrics. Sanger sequencing was used to determine the participants’ genotypes. Results: The rs2032582 genotypes and alleles were not associated
