Fixation of Efficient Method for Separation and Analysis of Alkyl Al koxy Silan Compounds by Gas Chromatography
...Show More Authors

       Modification of gas chromatographic technique for the separation and determination of methyl ethoy silane compounds which were synthesized by the addition of absolute ethanol to methyl chlorosilane compounds have been elaborated experimentally.  The addition of absolute dry ethanol to methyl chlorosilane compounds in the presence of a dry stream of nitrogen gas led to sweep out the liberated HCl gas. This method was found to be the suitable method for the preparation of methyl ethoxy silane compounds. The optimum parameter selected after careful and precise studies was between 20 – 30 ml \ min to carrieir gas flow rate, while applied temperatures of detector and injection part were 250 °C   and 225 °C respectively. The results showed that suitable chromatographic column for the separation of methyl chloro silane compounds is 50% [5% dioctyl phthalate ] + 50% [10% OV- 101 ] .While 10 % OV – 101 column was found to be the best for the separation of methyl ethoxysilane compounds . Accordingly  , a linear relationship for the calibration curve between concentration and peak area is achieved for methyl chlorosilane and methyl ethoxysilane . Correlation coefficients here ranged between 1 – 0.9991. The results of percentage RSD alotarned for the methyl chlorosilane and methyl ethoxysilane were 0.512.08 and 0.053-1.37 respectively.

A Study of Water Flux through Forward Osmosis Membrane Using Brine\Fresh Water System
...Show More Authors

The present work aims to improve the flux of forward osmosis with the use of Thin Film Composite membrane by reducing the effect of polarization on draw solution (brine solution) side.This study was conducted in two parts. The first is under the effect of polarization in which the flux and the water permeability coefficient (A) were calculated. In the second part of the study the experiments were repeated using a circulating pump at various speeds to make turbulence and reduce the effect of polarization on the brine solution side.
A model capable of predicting water permeability coefficient has been derived, and this is given by the following equations:
Z=Z+C.R.T/9.8(d2/D2+1) [Exp. [-9.8(d

Desulphurization of Simulated Oil Using SAPO-11 with CNT's as Adsorbent: A Kinetic Study
...Show More Authors

In this study, sulfur was removed from imitation oil using oxidative desulfurization process. Silicoaluminophosphate (SAPO-11) was prepared using the hydrothermal method with a concentration of carbon nanotubes (CNT) of 0% and 7.5% at 190 °C crystallization temperature. The final molar composition of the as-prepared SAPO-11 was Al2O3: 0.93P2O5: 0.414SiO2. 4% MO/SAPO-11 was prepared using impregnation methods. The produced SAPO-11 was described using X-ray diffraction (XRD) and Brunauer-Emmet-Teller (N2 adsorption–desorption isotherms). It was found that the addition of CNT increased the crystallinity of SAPO-11. The results showed that the surface area of SAPO-11 cont

Design of a Sustainable City in Iraq Using SAM Program to Calculate Renewable Energy
...Show More Authors

    Urban design and human activity are main causes of environmental pollution and climate change, such as reliance on energy production plants, factories and transportation that depend on fossil fuels, in addition to transformation of most green areas into residential areas. This paper aims to establish a sustainable city with an environment friendly urban design that contributes to exploitation of natural resources in the generation of electric power, use of green means of transport and thus the reduction of pollution. Anah site was chosen as the best site for designing a sustainable city, with its natural resources, air quality and moderate climate. The total area of ​​the city is 9990187m2 divided into s

Seasonal Variations Of Attached Cyanophyceae Algae on Cocreate Brideges In Tigress Rivere From Baghdad
...Show More Authors

The attached Cyanophyta community is a model for monitoring aquatic systems and interpreting environmental change in aquatic systems. The present study aims to conduct a seasonal study on Cyanophyta attached to the concrete abutments of three bridges (Al-Jadriya Bridge, Bab Al-Moadam Bridge, and Al-Muthanna Bridge) in the Tigris River within the city of Baghdad, central Iraq (from October 2021 to June 2022). The study included the quality of Cyanophyta and, the eleven environmental parameters (water temperature, electric conductivity, salinity, pH, total alkalinity, Calcium, Magnesium, dissolved oxygen, total dissolved solids, total phosphorus, and total nitrogen). Monthly samples were taken from the water under each bridge from three sa

Aesthetics of Color Rhythm in the Guiding Poster: خليف محمود خليف -معتز عناد غزوان
...Show More Authors

The idea of rhythm is basically associated with movement, as it is a regular frequency of movement combining between unity and change. Rhythm can be defined as a repetition of a certain element. Rhythm has a major role in the guiding poster which we are today in dire need for in light of escalation of coronavirus pandemic and its dire repercussions on entire international community, as the current research highlights the aesthetics of color rhythm in the guiding poster to confront coronavirus pandemic.

The spread of this invisible unknown horror preoccupied the world in different fields of scientific and human knowledge to the extent that man today has started looking for effective medical solutions to put an end to this pandemic

Dose Dependent Anti-inflammatory Effect of Ammi majus Alcoholic Extract in Rat: Chronic Study
...Show More Authors

During treatment of inflammatory diseases, many conventional therapies (non-steroidal anti-inflammatory drugs) used to relief pain and inflammation. Chronic use of  the intended drugs is frequently associated with serious side effect, which may lead to discontinuation of treatment . The efficacy and dose- response effect of ammi majus extraxt  (2 , 4, 8 , 16, and 32 mg/rat) were assessed using  formalin to induce paw edema in rats as a model of chronic inflammation respectively. In this study,  42 rats were used and allocated into 7  groups each containing 6 rats, representing control (Distilled  water) , standard (piroxicam ) and test extract ( 2 , 4 , 8 , 16 and 32 mg/rat of Ammi majus alcoholic e

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
