Chronic viral hepatitis is an important health problem in the world, where hepatitis B virus (HBV) or hepatitis C virus (HCV) infections are the main causes of liver insufficiency. The study included 100 blood samples from patients with chronic viral hepatitis, fifty of them with HBV infection and 50 with HCV infection. Twenty apparently healthy age and gender matched subjects were included as a control group. Out of the 50 patients with HBV, 36(72%) were males and 14(28%) were females. Thirty two (64%) patients with HCV were males and 18(36%) were females. The mean age for HBV patients was 36.9 ± 15.8 year and for HCV patients it was 39.9 ±14.2 year. The results of the liver function tests showed no significant difference between HBV and HCV patients. Both of HBV and HCV patients showed a significant difference regarding liver function tests when compared with the control group. Total white blood cell count and hemoglobin concentration were lower (4296± 1050.9 cell/ mm3 and 10.9 ± 2.2g/dl respectively) in HCV patients than those in HBV patients (6224 ± 1749.1 cell /mm3 and 13.4 ±1.3 g/dl ) with a significant difference. However there was no significant difference between HBV patients and control regarding total white blood cell count and hemoglobin concentration. Aim of study: to compare between chronic hepatitis B, chronic hepatitis C and control regarding some hematological and biochemical parameters.
In this paper, estimation of system reliability of the multi-components in stress-strength model R(s,k) is considered, when the stress and strength are independent random variables and follows the Exponentiated Weibull Distribution (EWD) with known first shape parameter θ and, the second shape parameter α is unknown using different estimation methods. Comparisons among the proposed estimators through Monte Carlo simulation technique were made depend on mean squared error (MSE) criteria

The article critically analyzes traditional translation models. The most influential models of translation in the second half of the 20th century have been mentioned, among which the theory of formal and dynamic equivalence, the theory of regular correspondences, informative, situational-denotative, functional-pragmatic theory of communication levels have been considered. The selected models have been analyzed from the point of view of the universality of their use for different types and types of translation, as well as the ability to comprehend the deep links established between the original and the translation.
