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.
Case Report.
To present a case of a previous complicated mandibular orthognathic surgery that aimed to setback the mandible in a female cleft lip and palate (CLP) patient, which led to bone necrosis on one side with subsequent severe mandibular deviation and facial asymmetry. We additionally reviewed the previous reports of similar complications, the pathophysiology and the factors that could lead to this dreadful result.

A computational investigation is carried out in the field of charged –particle optics with the aid of numerical analysis method using the personal computer. The work is concerned with the design of electron gun with space-charge effect. The Finite element method (FEM) used in the solution of Poison's equation for determine the axial potential distribution of the two-electrode immersion lens operated under zero magnification condition , and from the solution of the paraxial ray equation the optical properties such as the focal length , spherical and chromatic aberration coefficients are determined, also a calculation of the brightness and perveance for the lens. The electrodes geometry was determined in two and three dimensi

High smoke emissions, nitrogen oxide and particulate matter typically produced by diesel engines. Diminishing the exhausted emissions without doing any significant changes in their mechanical configuration is a challenging subject. Thus, adding hydrogen to the traditional fuel would be the best practical choice to ameliorate diesel engines performance and reduce emissions. The air hydrogen mixer is an essential part of converting the diesel engine to work under dual fuel mode (hydrogen-diesel) without any engine modification. In this study, the Air-hydrogen mixer is developed to get a homogenous mixture for hydrogen with air and a stoichiometric air-fuel ratio according to the speed of the engine. The mixer depends on the balance between th

Experimental investigation for small horizontal portable wind turbine (SHPWT) of NACA-44, BP-44, and NACA-63, BP-63 profiles under laboratory conditions at different wind velocity range of (3.7-5.8 m/s) achieved in present work. Experimental data tabulated for 2, 3, 4, and 6- bladed rotor of both profiles within range of blade pitch angles . A mathematical model formulated and computer Code for MATLAB software developed. The least-squares regression is used to fit experimental data. As the majority of previous works have been presented for large scale wind turbines, the aims were to present the performance of (SHPWT) and also to make a comparisons between both profiles to conclude which is the best performance. The overall efficiency and el
... Show MoreThis paper deals with two preys and stage-structured predator model with anti-predator behavior. Sufficient conditions that ensure the appearance of local and Hopf bifurcation of the system have been achieved, and it’s observed that near the free predator, the free second prey and the free first prey equilibrium points there are transcritical or pitchfork and no saddle node. While near the coexistence equilibrium point there is transcritical, pitchfork and saddle node bifurcation. For the Hopf bifurcation near the coexistence equilibrium point have been studied. Further, numerical analysis has been used to validate the main results.
