Hepatitis B and Hepatitis C viruses are the major health problem in the worldwide. In the Middle East, the prevalence of HBV in general population with the chronic infectionsis 2-5%,whereas the prevalence of HCV is about 1% in Arabian Gulf countries. World Health Organization (WHO) revealed that the risks of HBV and HCV transmissionas well as human immunodeficiency virus (HIV) through the transfusion of contaminated blood and blood products is high, because of the fragility of health services in these countries. Several viral diseases are transportby different modes like bloodtransfusion, sexual contact, and unsafe injections. The mostcommon blood-transmitted viruses are hepatitis B virus(HBV), hepatitis C virus (HCV) and humanimmunodeficiency virus (HIV);which cause fatal and chronic disorders. The prevalence ofthese viruses varies in Asia and developing countries depending on nationality, geography and lifestyle, sex, race, and educational levels. For all these previous causes, thisstudydesigned to know the seroprevalenceof HBV, HCV and human retroviruses(HIV-1, 2) among inpatients and outpatients of Balad General Hospital in Saladin governorate in Iraq. The study conducted in Balad General Hospital. Subjects with hepatitis C, B viruses, and HIV recorded from January2017 to December 2017. The age of patients ranged from 6 to 70 years; and the total number of tested serum samples was 32,942 serum samples. The highest percentage of HBVprevalence was in July by using ELISA technique (11.1%) for outpatients followed by 15.40% for outpatients in May by using anti-HBV strip.While the highest percentage of HCV prevalence was recorded in July by using ELISA technique (11.73%) for outpatients followed by 14.76% for outpatients in May by using anti-HCV strip. The percentage of patients infected with HBV in both sexes (females and males) was higher than the percentage of patients infected with HCV (1.80%vs.0.57%, respectively). Also, the present study indicated the seroprevalence of HBV (anti-HBV) was 38.27% for female and 41.02% for male with age range 21-30 years, and this significantly higher than in HCV which thepercentage of the seropositive cases were 37.03% in female and 39.13% in male with age range 41-50 years.Therewere no significant differences betweenthe seroprevalences of eachof anti-HCV Ab,anti-HBV Ab and HBsAg,and only 2 cases (0.03%) were seropositive for HIV-1, 2. Although, the HBV and HCV in Iraq are a major problem for the community and viral infectious diseases;the current study revealed that Iraq has a low prevalence for HBsAg, HBV, HCV and HIV.
Artificial lift techniques are a highly effective solution to aid the deterioration of the production especially for mature oil fields, gas lift is one of the oldest and most applied artificial lift methods especially for large oil fields, the gas that is required for injection is quite scarce and expensive resource, optimally allocating the injection rate in each well is a high importance task and not easily applicable. Conventional methods faced some major problems in solving this problem in a network with large number of wells, multi-constrains, multi-objectives, and limited amount of gas. This paper focuses on utilizing the Genetic Algorithm (GA) as a gas lift optimization algorit
In this research, the problem of multi- objective modal transport was formulated with mixed constraints to find the optimal solution. The foggy approach of the Multi-objective Transfer Model (MOTP) was applied. There are three objectives to reduce costs to the minimum cost of transportation, administrative cost and cost of the goods. The linear membership function, the Exponential membership function, and the Hyperbolic membership function. Where the proposed model was used in the General Company for the manufacture of grain to reduce the cost of transport to the minimum and to find the best plan to transfer the product according to the restrictions imposed on the model.
In this paper, the dynamic behaviour of the stage-structure prey-predator fractional-order derivative system is considered and discussed. In this model, the Crowley–Martin functional response describes the interaction between mature preys with a predator. e existence, uniqueness, non-negativity, and the boundedness of solutions are proved. All possible equilibrium points of this system are investigated. e sucient conditions of local stability of equilibrium points for the considered system are determined. Finally, numerical simulation results are carried out to conrm the theoretical results.
This paper presents a vibration suppression control design of cantilever beam using two piezoelectric patches. One patch was used as an actuator element, while the other was used as a sensor. The controller design was designed via the balance realization reduction method to elect the reduced order model that is most controllable and observable. the sliding mode observer was designed to estimate six states from the reduced order model but three states are only used in the control law. Estimating a number of states larger than that used is in order to increase the estimation accuracy. Moreover, the state estimation error is proved bounded. An optimal LQR controller is designed then using the estimated states with the slid
... Show MoreFeedback on students’ assignments can be done in many different ways. Nowadays, the growing number of students at universities has increased the burden on the instructors to give feedback on students’ writings quickly and efficiently. As such, new methods of modern online automated feedback tools, such as Hemingway app and ecree,are used to assist and help instructors. Hence, this research is an explanatory study to examine the effect of using the online automated feedback on some Iraqi EFL learners’ writings at the university level. The study comprised 60 students enrolled in an English language course at the University of Anbar. They were divided randomly into two groups, experi

Minister Yacoub Ben Keles distinguished himself with leadership and administrative talents, as well as his abilities in the field of jurisprudence, which made him the top political, administrative and cultural scene of the Fatimid state and left its mark on it by influencing its fateful decisions.
He was the son of Kels of the Jews of Baghdad, where he learned writing and arithmetic, and moved with his father to Syria and then carried him to Egypt.
Egypt embraced the son of Kels, living in a transitional period from the Achaishid era to the Fatimid period. Both these two covenants reconciled this man to his career until he became minister in the Fatimids in 368 A.H. / 978 A.D.
His character was overshadowed by most of the state'
