Role of Carbon Dioxide on the Corrosion of Carbon Steel Reinforcing Bar in Simulating Concrete Electrolyte

The main factors that make it possible to get the corrosion of reinforcing steel in concrete are chloride ions and the absorption of carbon dioxide from the environment, and each of them works with a mechanism which destroys the stable immunity of rebar in the concrete. In this work the effect of carbon dioxide content in the artificial concrete solution on the corrosion behavior of carbon steel reinforcing bar (CSRB) was studied, potentiostatically using CO2 stream gas at 6 level of concentrations;  0.03 to 2.0  weight percent, and the effect of rising electrolyte temperature was also followed  in the range 20 to 50 C. Tafel plots and cyclic polarization procedures were obeyed to investigate the corrosion parameters and pitting susceptibility respectively. The change in the microstructure and morphology of the CSRB after polarization in the simulate concrete solution was studied using optical and atomic force microscopes. The results show that the corrosion rate of the CSRB in artificial concrete greatly increases with the existence of CO2 gas and highly depends on its concentration in the range 0.03 to 2.0% .No sign for pitting corrosion is recorded at all CO2 concentrations and the general corrosion is the main problem in the conditions under consideration.

The Effect of Cadmium Selenide Thin Film Thickness on Carbon Monoxide Gas Sensing Properties prepared by Plasma DC-Sputtering Technique

     Cadmium Selenide (CdSe) thin films have been deposited on a glass substrate utilizing the plasma DC-sputtering method at room temperature at different deposition time in order to achieve different films thickness, and studied its sensitivity to the  carbon monoxide CO gas which are show high response as the film thickness increases, the DC-conductivity and photoconductivity are also studied and which are increased too as the film thickness increases, that indicates the good semiconducting behavior at room  temperature and light environments.

The role of prophetic Sunna in solution of social problems

Allah created the human from clay and made the system of marriage between male
and female as a reason for life continuity and human staying. This system produced an
organization called (the society) which is defined as a group lived in limited time and place.
Islam put fundamental and conditions of the righteous society in the Holy Quran and
prophetic sunna. Islam also put the solutions for problems (if they got) , naturally, these
problems may happened because of the nature of the life.
The problem of the research is summarized by that the problems of the society
enlarged in our Islamic society more than time ago. In the same time , some solution are
imported from west and east and from scientist and ignorant wit

Role of Cooperative Legislation in the Limitation of Informal Employment

In this study we examine the role that cooperative legislation can play in reducing informal employment. Cooperatives are considered the window of the social economy, which plays a major role in complementing traditional markets and collective labor, thus embracing the informal economy as the lifeboat for marginalized and excluded groups. Cooperatives come to regulate the informal economic sector as one of the options available for organization, by providing cooperatives in the provision of services and not by access to natural resources, and by facilitating the participation of decision makers in building skills for young people By supporting their ability to innovate, gaining the confidence of donor financial institutions, and ultimate

The Role of Banking Governance in Guarantee of Credit Risks

Risks are linked to banking activities. In order to overcome these risks, the bank has only the ability to rely on guarantees that are various and varied. These include traditional guarantees such as personal guarantees, commercial and real estate mortgages, insurance operations, specialized to cover the risks of foreign trade operations.

Including the procedures and procedures that the banking institution should abide by in the practice of its credit activities both before and after the grant to detect the risks surrounding them early and address them before they grow, by following the rules of banking governance of forming specialized committees in the bank, Monitoring credit operations and reviewing the credit portfolio to asc

The role of the currency sale window in the stability of the dinar exchange rate and its reflection on inflation

The: currency Auction is one of the monetary policy tools created after 2003, in order to keep pace with the changes that the monetary and financial policies will witness from financial openness and expectations of high levels of liquidity after international economic restrictions. It is necessary to re-evaluate the work of the currency Auction from time to time and observation its efficiency in adjustment the exchange rate And its reflection on the general level of prices as one of the objectives of its inception, and during the analytical aspect, it was confirmed that the currency Auction for selling the currency had a major role in adjustment the exchange rate and controlling inflation levels, due to the market’s dependence

Theoretical Computation of Electron Density in Laser-Induced Carbon Plasma using Anisimov Model

In this work, electron number density calculated using Matlab program code with the writing algorithm of the program. Electron density was calculated using Anisimov model in a vacuum environment. The effect of spatial coordinates on the electron density was investigated in this study. It was found that the Z axis distance direction affects the electron number density (ne). There are many processes such as excitation; ionization and recombination within the plasma that possible affect the density of electrons. The results show that as Z axis distance increases electron number density decreases because of the recombination of electrons and ions at large distances from the target and the loss of thermal energy of the electrons in high distance
