Excess alcohol consumption is associated with numerous metabolic changes and homeostasis disturbances of many macro- and micro-elements in the body. It has been associated with multiple pathologies at all levels. In the digestive apparatus, alcohol has generally been related to its toxic effects upon the liver. Alpha-1 antitrypsin (α-1 AT or AAT) plays an important role in controlling inflammation, coagulation and repair mechanisms in the body and most α-1 AT in the body is produced by the liver; from the other hand, Intrinsic factor (IF), which is a glycoprotein produced by the parietal cells of the stomach is necessary for the absorption of vitamin B12 in the small intestine. This study was designed to assess serum levels of α-1 AT and anti-IF Abs (IgG) among heavy alcoholics to clarify the relationship between alcohol addiction and such liver and/or stomach disorders. Fifty-four consecutive alcohol-dependent males were enrolled as a target group and 30 age matched males were considerate as a control group. The level of alpha-1 antitrypsin (α-1 AT) and anti-intrinsic factor (IF) antibodies were investigated by single radial immunodiffusion (SRID) and enzyme-linked immunosorbent assay (ELISA) respectively. We found from a total of 54 alcoholic patients that the mean age of patients is 37.5 years with a progressive increase in cases at third decade of age. They reported an average addiction period of more than 18 years. Most patients (93%) were currently smoking; and 18.5% were psychiatric; about 9% of them used to have co-addictions like heroin, valium and artin; another 9% had multiple sclerosis. We observed a non significant decrease of α-1 AT levels in alcoholics compared to control group (p>0.05), while there was a high significant increase in the level of anti-IF Abs in alcoholics, sera compared with control group (p<0.05). Furthermore; the serum level of α-1 AT and anti-IF Abs in alcoholic group are not related to age of starting consumption of alcohol. Specifically, we found no significant differences in the levels of α-1 AT and anti-IF Abs between those who start drinking prior to age 18 years (N=32), and after age 18 years (N=22) p>0.05. On the other hand; there is a statistically significant correlation between α-1 AT levels and the duration of alcohol consumption (p<0.05); similarly; theere was a highly significant correlation between the levels of anti-IF Abs and the duration of alcohol consumption was observed (p<0.05).The results suggest that Excess alcohol consumption is associated with numerous metabolic changes and homeostasis disturbancesof many macro- and micro-elements in the body. It has been associated with multiple pathologies at all levels.
Future generations of wireless networks are expected to heavily rely on unmanned aerial vehicles (UAVs). UAV networks have extraordinary features like high mobility, frequent topology change, tolerance to link failure, and extending the coverage area by adding external UAVs. UAV network provides several advantages for civilian, commercial, search and rescue applications. A realistic mobility model must be used to assess the dependability and effectiveness of UAV protocols and algorithms. In this research paper, the performance of the Gauss Markov (GM) and Random Waypoint (RWP) mobility models in multi-UAV networks for a search and rescue scenario is analyzed and evaluated. Additionally, the two mobility models GM and RWP are descr

Education in it s different levels becomes development in any country. There fore, nations pay great attention to educational systems, because they perceive that preparing human resources is essential to the development of these nations.
The present study deals with the a academic frames which formulate education in each educational system such as educational philosophy , educational aims , educational strategies by which the academic frames are carried out, which is limited to curriculum, teacher preparations, school activities, in addition to guidance and counseling.
This study reaches some conclusion which are derived from the description of the academic and practical frames some suggestion are made for the mechanism which facil

Development of a precise and delicate reaction has been acquired for the determination of vancomycin hydrochloride using batch and cloud point extraction (CPE) methods. The first method is based on the formation of azo dye as a result of diazotized dapsone coupled with vancomycin HCl (VAN) in a basic medium. The sensitivity of this reaction was enhanced by utilizing a nonionic surfactant (Triton X-114) and the cloud point extraction technique (second method). The azo dye formed was extracted into the surfactant-rich phase, dissolved in ethanol and detected at λmax 440 nm spectrophotometrically. The reaction was investigated using both batch and CPE methods (with and without extraction), and a simple comparison between the two

The study highlighted the transformation of value systems and educational patterns between past and present, especially with the introduction of modern variables and means, such as mobile phones, the internet, social media, and others. These factors have contributed both positively and negatively to the study. The study highlights the integral role of the school in collaboration with the family in guiding and educating children. It also emphasizes the active role of the school in developing students' abilities and skills, either attracting them to school or vice versa. This includes an examination of the essential skills required in education and their role in achieving a state of psychological well-being and systematically developing child

In this study, a genetic algorithm (GA) is used to detect damage in curved beam model, stiffness as well as mass matrices of the curved beam elements is formulated using Hamilton's principle. Each node of the curved beam element possesses seven degrees of freedom including the warping degree of freedom. The curved beam element had been derived based on the Kang and Yoo’s thin-walled curved beam theory. The identification of damage is formulated as an optimization problem, binary and continuous genetic algorithms
(BGA, CGA) are used to detect and locate the damage using two objective functions (change in natural frequencies, Modal Assurance Criterion MAC). The results show the objective function based on change in natural frequency i
