Artificial neural network and response surface methodology for modeling oil content in produced water from an Iraqi oil field
...Show More Authors
ABSTRACT<p>The majority of the environmental outputs from gas refineries are oily wastewater. This research reveals a novel combination of response surface methodology and artificial neural network to optimize and model oil content concentration in the oily wastewater. Response surface methodology based on central composite design shows a highly significant linear model with P value &lt;0.0001 and determination coefficient R2 equal to 0.747, R adjusted was 0.706, and R predicted 0.643. In addition from analysis of variance flow highly effective parameters from other and optimization results verification revealed minimum oily content with 8.5 ± 0.7 ppm when initial oil content 991 ppm, temperature 46.4 °C, pressure 21 Mpa, and flowrate 27,000 m3/day which is nearly closed to suggested oily content 8.5 ppm. An artificial neural network (ANN) technique was employed in this study to estimate the oil content in the treatment process. An artificial neural network model was remarkably accurate at simulating the process under investigation. A low mean squared error (MSE) and relative error (RE) equal to 1.55 × 10−7 and 2.5, respectively, were obtained during the training phase, whilst the testing results demonstrated a high coefficient of determination (R2) equal to 0.99.</p>

The role of credit policies in agricultural development: The activity of co-operative agricultural bank as a case study
...Show More Authors

The objective of this study is to explain the role of credit policies in agricultural development of Iraq during the period 1979-1989 which were represented by the policy of co-operative agricultural bank the organization that responsible to finance agricultural sector for various reasons. It has been shown that there was no clear credit policy existed during the period concerned due to the differences between loans from year. The loan growth rate was low in general comparing with objectives of the agricultural development plans, a low production rates comparing with loans paid, the growth rate of average number of trees in each donum and the growth rate of livestock number was also low.In conclusion there should be a clear plan for cred

Localization of transforming growth factor-beta expression in the peri-implant tissues of dental implants coated with placental collagen
...Show More Authors

Back ground : The transforming growth factor beta (TGFB) signaling pathway is involved in many cellular processes in both the adult organism and the developing embryo including cell growth, cell differentiation, apoptosis. The interaction between implant material and surrounding tissues is believed to play a fundamental role in implant success and illustrates different expression of growth factors by different cells that involved in the formation of peri-implant tissue. The aim of this study was to localize expression of TGF B by newly formed bone tissue around surface-conditioned implants with placental collagen at different time intervals: 3 ,7,14,28, and 56 days . Materials and Methods: Commercially pure Titanium (CPTi) implants coated w

תאור השטטל ביצירות סופרים עבריים מאת עוזר לפרופ. עדנאן שביב ג'אסם Description of Shtetl in Works of Hebrew writers
...Show More Authors

מחקר זה עוסק בנושא (העיירה היהודית) שטטל ביצירותיהם של שני סופרים עבריים שהתמקדו בביקורת בשטטל. וזה נחשב להגבלה או למכשול לפיתוחם של היהודים, אז זה התרחש ביצירותיהם והם נתנו תשומת לב רבה לזה –לפי דעתם- גם זה נחשב להיבט בהיסטוריה והחיים של היהודים באירופה.

 סופרים עבריים רבים התעסקו בנושא השטטל שנהיתה לחומר ביצירותיהם. גם כן נהיתה אצל כמה מהם לשאלה חשובה, כי אם  אנו מוצאים שיצירותיהם לא נטשו את האזכור

The Level of Educational Supervisors' Practices of Their Supervisory Duties According to The Requirements of Comprehensive Quality in Oman
...Show More Authors

The research aims to identify the level of educational supervisors' practices of their supervisory duties according to the requirements of comprehensive quality from the viewpoint of teachers in Oman. Moreover, identify the differences between the responses of the sample about these practices, which are attributed to gender, and years of experience. Thus, a questionnaire was administered to teachers, consisting of (48) items distributed on (5) main fields related to the educational supervisor's practices. The sample consisted of (220) teachers who were randomly chosen from the schools in Dhofar region. Data were analyzed using means, standard divisions, T-test, and One Way ANOVA. The research concluded that the level of educational super

“Violence is the woman you never had” : Trauma of Women in Christina Reid's The Belle of the Belfast City
...Show More Authors

This paper examines The Belle of the Belfast City by Christina Reid through the lens of trauma theory as outlined by Judith Herman and Cathy Caruth. The play depicts the influence of the Troubles in Northern Ireland as a religious and sectarian conflict between Protestants and Catholics on women. Reid's work is mainly about the reunion of three generations of working-class Protestant women during the time of the Anglo-Irish agreement in 1985.The play's female characters face many obstacles, including racism, forced migration, religious persecution, economic struggle, social exclusion, and abuse. The study presents how religion is used as a tool to justify violence against women. Women become targets of verbal and physical abuse, violence, a
