Numerical modeling of two-dimensional simulation of groundwater protection from lead using different sorbents in permeable barriers
...Show More Authors

This study is to investigate the possibility of using activated carbon prepared from Iraqi date-pits (ADP) which are produced from palm trees (Phoenix dactylifera L.) as low-cost reactive material in the permeable reactive barrier (PRB) for treating lead (Pb<sup>+2</sup>) from the contaminated groundwater, and then compare the results experimentally with other common reactive materials such as commercial activated carbon (CAC), zeolite pellets (ZP). Factors influencing sorption such as contact time, initial pH of the solution, sorbent dosage, agitation speed, and initial lead concentration has been studied. Two isotherm models were used for the description of sorption data (Langmuir and Freundlich). The maximum lead sorption capacities were measured for ADP, CAC, and ZP and were found to be 24.5, 12.125, and 4.45 mg/g, respectively. The kinetic data were analyzed using various kinetic models particularly pseudo-first-order, pseudo-second-order, and intraparticle diffusion. COMSOL Multiphysics 3.5a depend on finite element procedure was applied to formulate transmit of lead (Pb<sup>+2</sup>) in the two-dimensional numerical (2D) model under an equilibrium condition. The numerical solution shows that the contaminant plume is hindered by PRB.

Dumping Policy & Its Impact In The Development of Agricultural Production In Iraq (2003- 2009)
...Show More Authors

Dumping policy considered as one of the policies occurs severe damages to the developing countries apparently this is happens due to the potential weakness in (productive, technical, legislative, legal institutions) comparing with other developed countries who are members in WTO.

Iraq consider as one of the developing countries that has been effected by the dumping policy, the events in Iraq since downfall of the formal regime, and the allied forces domination of Iraq have all together accelerated in the apace of deterioration , particularly , after the temporary coalition authority  has forced Iraq to adopt a free foreign trade policy& exclusion of the state from the market mechanism & to consolidate import and deac

The Effect of The Round Robin Strategy in Logical Thinking the Fourth in Chemistry
...Show More Authors

The study aims to identify the impact of the round-robin strategy on the logical thinking of fourth-year middle school students in chemistry. Two groups were employed:  an experimental group consisted of (30) students who were taught according to the round-robin strategy, and the control group consisted of (30) students who were taught according to the traditional method. The researcher adopted the experimental design with partial control by preparing the visual thinking test tool, which consists of (20) multiple-choice items, it was applied as a post-test on the research sample. The result showed that there was a statistically significant difference in favor of the experimental group, which was taught according to the Round Robin s

Assessment of Inflammation, Comorbidity and Demographic Factors in Patients with Kidney Disease in Baghdad
...Show More Authors

     Inflammation markers are significantly higher among hemodialysis (HD) patients, which have been associated with chronic activation of the immune system. Hemodialysis centers in Baghdad appear to be taking measures with low adequacy and frequency of dialysis sessions, which can be a reason for decreased kidney functions. Therefore, the objective of this study focuses on the assessment of different aspects of hemodialysis for regular HD patients in Baghdad, including inflammatory markers (serum C-reactive protein, CRP, and erythrocyte sedimentation rate, ESR), dialysis dose, comorbidities, and demographic factors for a period of one year (2018), the assessment covered four major hospitals in Baghdad namely (Al-Kind

Identification of genetic mutations associated with autism in GABRB3 gene in Iraqi autistic patients
...Show More Authors

This study was aimed to detect and identify genetic mutations in γ-aminobutyric acid receptor β3 subunit encoding gene (GABRB3) and its association with autism spectrum disorders. Forty autistic patients and 25 non-autistic as control group (5 unaffected sibling and 20 unrelated) with age range from 3 – 10 years were included in this study. Chromosomal DNA was extracted from blood samples followed by polymerase chain reaction (PCR) amplification of two targeted regions which include: (exon2-intron2-exon3) region and (exon 6) region of GABRB3 for subsequent DNA sequencing. Identical bands related to the targeted regions were present in all samples. A sample of PCR products of patients and controls were sequenced. Sequencing results re

The Influences of Aminophylline and Indomethacin in Glycerol-Induced Acute Renal Failure in Rats
...Show More Authors

Background: Adenosine mediates homodynamic
changes and resulted in the production of acute renal
failure (ARF) in female Albino-Wister rats, therefore,
adenosine level increases highly in ARF.
Objective: This experiment was designed to
investigate the effect of the adenosine antagonist
aminophylline and the adenosine agonist indomethacin on glycerol-induced ARF.
Method: Glycerol induced ARF was produced by a
single dose (10ml/kg, 50%v/v with distilled water i.m)
in rats, which were restricted to drinking water.
Aminophylline was used in our study in a dose of
25mg/kg, i.p) while the dose of indomethacin was
10mg/kg, i.p), assessment of renal function was done
by measuring blood urea
nitrogen (BUN

Status of HBeAg in association with other baseline tests in Iraqi patients with CHB
...Show More Authors

Chronic Hepatitis B(CHB) is a serious sequel after Hepatitis B Virus infection, although the rate of chronicity is inverse with age but it may be associated with a significant proportion of deaths related to cirrhosis and liver cancer. HBV serology and measurement of hepatocytic enzymes with viral load can predict disease prognosis and response to treatment. HBeAg refers to a high viral replication and associated with more infectivity to others. This study aimed to determine the impact of HBeAg status in chronically infected patients on various baseline tests. A total of 90 patients with CHB infection who were included in this study. Several standardized measures used for liver function tests, viral load and hepatitis B serological

B-Closed Topological Spaces in Terms of Grills
...Show More Authors

The concept of -closedness, a kind of covering property for topological spaces, has already been studied with meticulous care from different angles and via different approaches. In this paper, we continue the said investigation in terms of a different concept viz. grills. The deliberations in the article include certain characterizations and a few necessary conditions for the -closedness of a space, the latter conditions are also shown to be equivalent to -closedness in a - almost regular space. All these and the associated discussions and results are done with grills as the prime supporting tool.
