AIM:To assess the effectiveness of hepatitis B virus(HBV) vaccination program among fully vaccinated ***:A national community based crosssectional study was carried out in 6 governorates representing Egypt. A total of 3600 children aged from 9 mo to 16 years who were fully vaccinated with HBV vaccine during infancy were recruited. Face to face interviews were carried out and sera were evaluated for hepatitis B surface antigen(HBsA g),anti-HBV core antibodies(total) and quantitative detection of hepatitis B surface antibody using enzyme linked immunoassays techniques. Samples positive to HBs Ag/anti-HBV core antibodies were subjected to quantitative HBV-DNA detection by real time polymerase chain reaction with 3.8 IU/L detection limit. RESULTS:Sero-protection was detected among 2059 children(57.2%) with geometric mean titers 75.4 ± 3.6 IU/L compared to 3.1 ± 2.1 IU/L among nonseroprotected children. Multivariate logistic analysis revealed that older age and female gender were the significant predicting variables for having non seroprotective level,with adjusted odds ratio 3.3,9.1and 14.2 among children aged 5 to 0.05. C ON C LU S I ON :T he E gy pt ian c ompuls or y H B V vaccination program provides adequate protection. Occult HBV infection exists among apparently healthy vaccinated children. Adherence to infection control measures is mandatory.

Assemble of Dye Sensitized Solar Cell Based on Locally Available Natural Dye

引用

Journal of Atmospheric Science Research 2019年第1期2卷 32-36页

作者： samia Tabassum Ayesha Siddika Munira Sultana Mashudur Rahaman Muhammad Shahriar Bashar Institute of Fuel Research and Development Bangladesh Council of Scientific and Industrial ResearchDhakaBangladesh

Due to the availability, non-toxicity and cost-effectivity, natural dyes are becoming popular day by day. This study explains the fabrication method of dye-sensitized solar cells (DSSCs) using natural dyes containing anthocyanins extracted from pomegranate, blackberry and beetroot. Doctor blade method was employed to prepare TiO2 film as photoanode on FTO glass. The structural and morphological properties of photoanode was studied using X-ray diffraction (XRD) and Scanning Electron Microscopy (SEM), respectively. The extracted dye absorption was evaluated by UVVis- NIR spectroscopy. The fabricated cells have efficiency in the range of 0.015-0.042% which has been measured by sun simulator.
