The composite panels were analyzed using nonlinear three dimensional finite element models. The constitutive models of the nonlinear material behavior for ferrocement matrix, PSS, and steel wire mesh were used. ANSYS version 16.1 program code was used to analyze the three dimensional model. Ferrocement was modeled by using the 8-noded isoperimetric brick elements (SOLID65) with three degrees of freedom, while the profiled steel sheet was modeled as SHELL181 element with four-node element with six degrees of freedom at each node: translations in the x, y, and z directions, and rotations about the x, y, and z-axes. A nonlinear spring element, COMBIN14, was used to represent the mechanical connectors, while to simulate the adhesive epoxy layer solid element SOLID185 was used. It was defined by eight nodes having three degrees of freedom at each node: translations in the nodal x, y, and z directions. The wire mesh reinforcement was modeled as a volume ratio distributed within the ferrocement brick elements. The analytical results of load-deflection response have been compared with available experimental works.","PeriodicalId":23465,"journal":{"name":"University of Thi-Qar Journal","volume":"16 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2020-08-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"89913122","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The study showed the high values of most physical and chemical properties in the river water, which confirms the effect of the electric station. The samples were taken during the months of February and April of 2019. Six stations were chosen along the river in the study area, two stations before the electric station and two stations next to the station and two stations after the electrical station. The samples were taken from the edge of the river and from the middle and at a depth of (30) cm. The laboratory tests were conducted to calculate the electrical conductivity ,PH and the calcium and magnesium ion rates. The study of properties showed that all levels except PH are not in accordance with the Iraqi and global determinants of potable water as shown in Table (2). We also noticed that these rates were higher in February than in April due to the rain that swept the country and consequently the rise in the water level of the river, which led to a decrease in the percentage of pollutants.","PeriodicalId":23465,"journal":{"name":"University of Thi-Qar Journal","volume":"28 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2020-08-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"80650117","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The objective of the present work is to investigate experimentally the effect of heat flux, mass flux, vapor quality and saturation temperature on refrigerant flow boiling heat transfer characteristics in the evaporator of refrigeration system. These investigated parameters have significant impacts to enhance the thermal performance of the evaporator. The experimental investigations were conducted in smooth copper tube with inner diameter 5.8 mm and 600 mm length under different test conditions. The test conditions considered in this study were, for heat flux of 7.718-32.78 kW/m 2 , mass flux of 97.3-148.7 kg/m 2 .s , saturation temperature of 20.58 to -15.68 ̊C and vapor quality of 0.3-1. It can be concluded from the results that, the average heat transfer coefficient at relatively greater mass flux 148.7 kg/m 2 .s was higher in range of 21% compared to other mass fluxes at constant test conditions. The relatively higher value of heat transfer coefficient was observed at heat flux 32.78 kW/m 2 with average increase of 19% compared to the relatively lower value 23.38 kW/m 2 .

Study of the magnetic characterstics shows that some systems like Coronene-Carbon and Coronene-oxygen has the antiferromagnetic charactersti, this type of magnetic properties stands for open shel system which has two type of orbital α and β orbitals. Individual atoms calculations was achieved in order to make a comparison between Coronene and the atoms to demonstrate which of them will behave as a donor or an acceptor. E HOMO , E SOMO , E LUMO , total energy electronegativity and electrophilicity were evaluated for all paradigms under the study. Using DFT to study the symmetry shows that there are two types of point group symmetries C 6h /C 1 and Cs/C 1 . Coronene-Corbon posseses the highest dipole moment value among the samples, it has the value (5.5873 Debye), dipole moment credit is very important to give sight about the internal structure of substances. Calculations of chemical potential shows clearly Al, Ga and In behave as donors, while B, C and O behave as acceptors.
