It is also used in UV-light emitters, piezoelectric transducers. ZnO is in various forms, such as nanoparticles, Nano-belts, Nano-rods, nano-tubes, and nanowires. The purpose of this research is to review a general overview of ZnO and its application, the use of ZnO as an anti-reflection coating with various styles on the solar cells, and the conventional and unconventional techniques that had been used to coating the anti-reflection layers on the solar cell will be reviewed. This is based on a review of previous studies related to applications of anti-reflective coatings of ZnO and make a comparison of practical results was obtained with different semiconductor materials (SIC, TiO2, ZnS, SiO2, SiN4).

In this paper, at first we discuss about eight models in cloud computing, which are built upon three major services namel y IaaS, PaaS, SaaS and including other minor services such as, Hardware-as-a-Service (HaaS), Virtual Cluster-as-aService (ViteraaS). Then, paper tries to presents a solid comparison of these models according to a set of most common factors that any cloud models should have, identified from thoroughly researched multiple cloud-based articles. Finally, an evaluation of the comparison and exposes all the possible future works or implementation that can be considered, has proposed. The paper discusses factors that m ust be considered to choose the most suitable model for implementing certain functionality in cloud computing.

The doublet projector magnetic lens with cylindrical pole pieces has been designed. The radial and spiral distortions have been corrected by using this lens , after the magnetic field has been computed, by the use of computer programs based on the finite element method (FEM),this magnetic field has been used for calculation the projector focal properties for this lens. Where, a rotation and distortion free images have been obtain by suitable choice of the ratios values of gaps and bores of first lens and second lens.

The nanoparticles volumetric concentration of each family of as-prepared nanofluid ranged from 0.1 to 1.0 vol%, using as-received nanopowders, of 18 – 80 nm average particles size. Furthermore, the pH measuring apparatus and the measurement procedure were validated by determining the pH of commercially supplied calibration fluids, of pH 4, 7, and 10. Following the validation, pH correlations were obtained from the experimental measurements of the 0.1, 0.5, and 1.0 vol% nanofluids in terms of varied sonication bath temperatures and volumetric concentrations. Those correlations were then combined into one robust pHnf correlation and validated using the pH data of the 0.3 and 0.7 vol% nanofluids. The new proposed correlation was found to have a 2....

Considering that lead dampers as knee braces don't clog structural panels, so this characteristic can solve brace problems from architectural view. Knee brace has a good function in controlling seismic movements of multi-story structures. The results indicate that maximum displacements have been reduced up to between 20% and 60%. Lead dampers act properly in absorbing the energy induced by earthquake where these dampers dissipate about 60% of total energy.

Aim: The aim of this study was to detect P. jirovecii in sputum samples from patients suspected of having respiratory tract infections. Materials and Methods: In this study, 230 acid fast bacilli negative sputum samples from 230 patients presenting with respiratory tract infections submitted to three teaching hospitals' medical microbiology laboratories in Osun and Oyo States, Nigeria for routine investigation were examined for P. jirovecii by microscopical and polymerase chain reaction methods. Results: P. jirovecii cysts were observed in 15 (6.5%) samples and polymerase chain reaction was positive for 29 (12.6%) samples out of 230 samples examined. It was observed that the detection of P. jirovecii was associated with age (P < 0.05) while there were no associations between diagnosis, sex, and prevalence of P. jirovecii (P > 0.05). Polymerase chain reaction was showed to be a better method for the detection of P. jirovecii based on the 51.7% sensitivity and 100% specificity of the microscopy. Conclusion: The study concluded that P. jirovecii is prevalent in patients with respiratory tract infections in hospitals from the southwestern part of Nigeria and should be included in diagnosis of these infections in this part of the world.

Effect of long-term moderate physical exercise on plasma lipoproteins. The National Exercise and Heart Disease Project

Levels of total plasma cholesterol, high- and low-density lipoprotein (HDL and LDL) cholesterol, and triglycerides were measured. At baseline, alcohol intake, weight, and skin-fold thickness but not treadmill work capacity correlated with triglyceride or HDL cholesterol levels. After one year, no clinically important change in lipid levels was observed in either group. Using multiple regression analysis of the combined groups, changes in several independent variables, including work capacity change, were not predictive of changes in lipid levels. Thus, changes in levels of fitness and/or regular exercise did not substantially influence HDL cholesterol or other lipid levels.

Performance Measures and Level of Transit Service Assessment of Public Transport Bus Network in Baghdad City during 2002-2003

This system suffers from many problems, part of which were related to bus routes, while the other part was related to the bus and its operators. These problems have a direct effect on the users of public transport buses. The objective of this study was to assess the performance of eight public transport bus routes which they represented by the Al-Tahrir bus network and adopting the level of the transit service method. Seven transit performance measures were selected in this study, such as bus travel time, hours of service during the day, service frequency (headway), total delay on the route, running speed of the bus, bus occupancy, and capacity of the route. The results of this study showed that bus routes No. (72, 36, 13, 114, 11, 30, 37, and 9) were operating at overall Level of Transit Service LOTS (D, E, E, E, E, D, E, and E) respectively, whereas the bus network (Al-...
