ESTIMATION OF COEFFICIENTS AND SCALE PARAMETER FOR LINEAR (TYPE 1) EXTREME VALUE REGRESSION MODEL FOR LARGEST VALUES WITH APPLICATIONS
...Show More Authors

In this paper we estimate the coefficients and scale parameter in linear regression model depending on the residuals are of type 1 of extreme  value distribution for the largest values . This can be regard as an improvement for the studies with the smallest values . We study two estimation methods ( OLS  & MLE ) where we resort to Newton – Raphson (NR) and Fisher Scoring methods to get MLE estimate because the difficulty of using the usual approach with MLE . The relative efficiency criterion is considered beside to the statistical inference procedures for the extreme value regression model of type 1 for largest values . Confidence interval , hypothesis testing for both scale parameter and regression coefficients , goodness of fit statistics based on the observed residuals are considered . As a conclusion and  through the probability plot test we get no evidence against using the assumed residuals distribution.

Micronuclei Formation and Comet Assay in Women with Polycystic Ovarian Syndrome (PCOS)
...Show More Authors

Recently the polycystic ovary syndrome (PCOS) has been linked with DNA damage and genomic instability. Amis of this study to evaluated some parameters of genetic instability such as micronuclei and comet assay score in women with PCOS. Genotoxicity and cytotoxicity of DNA damage were evaluated by measured of micronuclei and comet assay in 25 patients with PCOS and 15 normal menstrual women as control group. The results showed higher significant differences in the level of micronuclei and comet score in patients with PCOS compared with normal women. We concluded that, the genetic instability more occurred in patients with PCOS when compared with control group.

E-Learning and Its Relationship with Academic Passion among Middle School Students
...Show More Authors

Abstract

The current research aims to identify the level of E-learning among middle school students, the level of academic passion among middle school students, and the correlation between e-learning and academic passion among middle school students. In order to achieve the objectives of the research, the researcher developed two questionnaires to measure the variables of the study (e-learning and study passion) among students, these two tools were applied to the research sample, which was (380) male and female students in the first and second intermediate classes. The research concluded that there is a relationship between e-learning and academic passion among students.

Folic Acid With Fluorene: A Complexation Study by UV and FTIR Spectroscopies
...Show More Authors

The complexation between folic acid and a typical polyaromatic hydrocarbon, fluorene, was investigated using FTIR and UV spectra. Appearance of a new IR band at 2401cm−1 demonstrates that NH2–C=N moiety on pterin ring in folic acid is protonated when fluorene is introduced. The emergence of two charge transfer bands at 217 nm and 278 nm in UV difference spectra shows the presence of π-π complexation between folic acid and fluorene. These experiments confirm that fluorene could combine with the pterin ring of folic acid through π-π donor–acceptor interaction and induce the protonation process in folic acid upon strengthening electron accepting ability of pterin ring. The results suggest that complexatio

Natural and Mixed Convection in Square Vented Enclosure Filled with Metal Foam
...Show More Authors

Steady natural and mixed convection flow in a square vented enclosure filled with water-saturated aluminum metal foam is numerically investigated. The left vertical wall is kept at constant temperature and the remaining walls are thermally insulated. Forced convection is imposed by providing an inlet at cavity bottom surface, and a vent at the top surface. Natural convection takes place due to the temperature difference inside the enclosure. Darcy-Brinkman-Forchheimer model for fluid flow and the two-equation of the local thermal non-equilibrium model for heat flow was adopted to describe the flow characteristics within the porous cavity. Numerical results are obtained for a wide range of width of the inlet as a fraction

Oxidative Stress and Some Liver Functions Parameters in Patients with Symptomatic Cholelithiasis
...Show More Authors

Background : Gallstone disease is one of a common surgical problem and one of the most common gastrointestinal diseases throughout the world but its pathogenesis remains unclear. Many theories have been put forward to explain the mechanism of stone formation. The living organism has enzymatic and non-enzymatic antioxidant systems neutralizing the harmful effects of the endogenous oxygen free radicals products. Under certain conditions, the oxidative or anti-oxidative balance shifts towards the oxidative status as a result of increase in oxygen free radicals and/or impairment in antioxidant mechanism.

Objective :To evaluate the oxidative stress markers (total antioxidants capacity and malondialdeh
