The University of Babylon is a university located in Babylon, Iraq. It consists of 20 colleges within three compounds, located seven kilometers south of the city of Hillah, in Babylon Province. The campus was originally the Administrative Institute of Babylon. Later some of the buildings were adopted for use by the medical college of the University of Kufa, before being established as a university in its own right in 1991.The university now teaches a wide variety of subjects, and during the 1990s, started teaching night classes. These became popular, especially among well-off families, after the increase in difficulty of high school examinations in 1997. Wikipedia.

This paper focused on behavior of beam strengthened with CFRP plate and effect of strengthening length. The simply supported steel beam tested in previous work was modeled using ANSYS finite element software, The same parameters as the experimental data were used to model the steel beam in FEA. Characteristic points on the load-deflection response curve predicted using finite element analysis (FEA) were compared to experimental data. The comparison shows that the ANSYS finite element program is capable of modeling and predicting the actual deformation behavior for steel beam. The FE model simulated in this study used to build continuous steel beam and strengthening it by using different length of CFRP plate as a ratio of beam length. The FE analysis result shows that the length of CFRP plate when reach (40% and 60%) of span length and total beam length in sagging and hogging regions respectively, the increased of ultimate strength of beam become growth slowly. © 2011 Elsevier Ltd.

This paper gives a comprehensive overview about the recent advances related with the application of the nanotechnology in various kinds of the solar collectors. Papers reviewed including theoretical, numerical and experimental up to date works related with the nanotechnology applications in the flat plate, direct absorption, parabolic trough, wavy, heat pipe and another kinds of the solar collectors. A lot of literature are reviewed and summarized carefully in a useful tables (Tables 1-7) to give a panoramic overview about the role of the nanotechnology in improving the various types of the solar collectors. It was found that the use of the nanofluid in the solar collector field can play a crucial role in increasing the efficiency of these devises. We think that this paper can be considered as an important link between the nanotechnology and all available kinds of the solar collectors. From the other side, further researches are required to study the effect of nanotechnology to enhance the solar collector industry over the next several coming years. © 2016 Elsevier Ltd.

The photocatalytic decolorization of industrial wastewater was investigated by using TiO2 and ZnO photocatalysts. Heterogeneous photocatalytic processes applied under natural weathering conditions, in the presence of solar radiation show a promising degradation capability. The complete removal of color could be achieved in a relatively short time of about 20 minutes, when ZnO was used and about 100 minutes when TiO2 was used under solar irradiation. However, in the presence of artificial UV-light, complete decolorization of textile industrial wastewater was obtained after less than one hour of irradiation when ZnO was used and in less than two hours, when TiO2 was used at the same temperature. The results indicate that the degree of photocatalytic decolorization of textile industrial wastewater was obviously affected by different parameters. These parameters include catalyst mass, type of catalyst, type of reactor, type of dye, dye concentration, and temperature. The procedure used in this research can be used as an efficient technology for solar photocatalytic decolorization of the colored wastewater discharged from the textile industry under the climatic conditions of most countries.

In the present paper, the effect of constant magnetic field on natural convection in a semi-circular enclosure that is filled with nanofluids (copper (nanoparticles) with pure water (base fluid)) with present heat flux is investigated numerically. The heat flux (q″) is supplied partly in the center of the base wall, and the other parts of base wall of the enclosure are assumed adiabatic. The center of the circular arc (-45°≤γ≤+45°) is assumed at constant cold temperature (Tc) and the other parts of the circular arc are adiabatic. The gravity (g) acts normal to the y-direction and the uniform external magnetic field (Bo) is applied parallel to gravity. Finite element method based on the variational formulation is employed to solve momentum and energy balance as well as post-processing streamfunctions and heatfunctions. The results are based on visualization of heat flow via temperature lines and heatfunctions, and fluid flow via streamfunctions. Comparisons with previously published work are performed and the results are found to be in good agreement. This paper examines the influence of pertinent parameters such as Rayleigh number (104≤Ra≤107), Hartmann number (0≤Ha≤80 step 20), and solid volume fraction of nanoparticles (0≤φ≤0.15 step 0.05) on the flow, temperature fields and the heat transfer performance of the enclosure.The results show that the heat transfer rate increases with an increase of the Rayleigh number and the nanoparticles volume fraction but it decreases with an increase of the Hartmann number. The effect of the magnetic field on heat transfer increases with the increase of Rayleigh number and it decreases with the increase of the nanoparticles fraction effect. © 2014 Elsevier Ltd. Source

The D.C and A.C electrical conductivity of (poly-methyl methacrylate - alumina) composite has been investigated. For that purpose, the PMMA samples with Al2O3 additive prepared with different percentages(0,15,25,35 and 45) wt.% and different thickness. The experimental results showed that the D.C electrical conductivity increased with increasing the alumina concentrations and temperature. Also the activation energy change with increasing of additional alumina. The dielectric constant, dielectric loss, A.C electrical conductivity are changed with change the concentration of the filler and frequency of applied electrical field. © EuroJournals Publishing, Inc. 2011.
