In this study, the prevalence of HCV infection was thoroughly evaluated among patients at all hemodialysis facilities in Imam Hussein Medical City, Karbala, Iraq. The study was conducted to investigate the prevalence, anti-HCV risk factors, and surface antigen of the hepatitis B virus (HBsAg) among Hemodialysis patients in the hemodialysis center/ Imam Hussein Medical City. This cross-sectional study was performed between October 2014 and May 2020 in Habib bin Mazher Center for hemodialysis in Imam Hussein Medical City, Karbala, Iraq. A total of 446 patients with end-stage renal failure who have been on Hemodialysis for at least five months and up to 4 years were involved in this study. Out of four hundred forty-six (446) patients, 5 (1.12%) patient was HBsAg positive, and 95 (21.30%) patients were diagnosed as anti-HCV seropositive. Only one patient showed infection with both HCV and HBV. From the study observation, the female gender, aged between 38-62 yrs., married, patients who lived in rural areas, were illiterate, or were housewives had the greatest rates of anti-HCV and HBsAg positive compared to the rest of the females. A patient with a positive history of blood transfusion 65(68.42%) (14.575) is more likely to be infected with C and B. The number of patients conducting dialysis in another Center is 50(52.63%), showing a great effect on the transmission of the virus. The main problem some nurses are not taking care of such not changing medical gloves when leaving the halls of people infected with HCV and HBV to those not infected. Dialysis in multiple has less protocol observation which causes the virus to transmit to the dialysis center. Some exercises or practices are unintentional negligence by dialysis maintenance engineers when working on a device in the (HCV) hall and the non-infected person's lobby without changing their medical gloves.

Welding is a key technology in the manufacture of engineering components. Welding is required in a variety of industries, including the automotive, construction, and aviation industries, among others. So many things would not exist without this type of metalwork, including numerous structures, gates, fences, minor kitchen appliances, cars, and even space exploration. The motivation behind this work was to empower a huge extent of the advanced technique to be finished by calculation. A ferrite steel weld ordinarily may contain in excess of fifteen significant solute increments. Its properties additionally rely upon the welding conditions and post-weld heat treatment. Consequently, it is a considerable assignment to endeavor to anticipate the yield and extreme rigidities, stretching, and Charpy sturdiness, which are all rudimentary plan boundaries. A gigantic dataset was ordered utilizing definite information from the distributed writing and enterprises to different neural organization examinations just as Genetic Algorithms. The Neural network is an exceptionally adaptable and incredible experimental technique, yet it is shown that with care, the organization can be prepared to perceive solid metallurgical connections. The subsequent models have been approved in an assortment of ways with accentuation on information already inconspicuous by the models. [ABSTRACT FROM AUTHOR]

The Natural Rubber (NR) blend with Styrene-Butadiene Rubber (SBR) loaded with different fraction ratios of NR were prepared. Various ratios of NR namely 25-55 part per hundred rubber part (phr) were prepared. The ratios of SBR ranging 45-75 phr from the masterbatch were blended. The rheological and mechanical properties of pure blends and those loaded with different fraction ratios of NR were investigated. Rheological properties analysis has been showing improvement in most blend ratio until 40 phr NR. Parameters such as initial, minimum and maximum torques, Mooney viscosity, and thermo-plasticity were recorded. The overall enhancement is observed in cure rate and induction time in relation with NR loading up to 50phr NR, then declined in above this ratio. The mechanical properties, namely hardness, tensile strength, and Young modulus were improved as NR content increases to nearly 40 phr NR while elongation improved by 35% only. The young modulus results show random behaviour and the maximum value was at the content of 40-45 phr NR. Accordingly, the 40 phr NR blend was found to exhibit the highest values of the most rheological and mechanical properties. [ABSTRACT FROM AUTHOR]
