Role of Carbon Dioxide on the Corrosion of Carbon Steel Reinforcing Bar in Simulating Concrete Electrolyte
...Show More Authors

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.

Studies and scientific research conducted in the field of communication have shown that broadcasting has a clear impact on the ideas, attitudes and behavior of the masses if it is better used in making the media message studied.

The role of this means is not only to present opinions and ideas, but also to influence trends by supporting or changing them. This is of course a matter for the nature of the content in terms of its formulation and the way it is prepared and presented. The power and appeal of a radio message is not complete by simply creating content without creating a distinctive design; and to what extent this content depends on the logic and psychology of persuasion.

Role of Serum Omentin-1 and Bone Metabolism Markersin Osteoporosis among Postmenopausal Women
...Show More Authors

menopause is the most common cause of accelerated bone loss in women. Omentin-1 is secreted by the visceral adipose tissue and it isdonated in the regulation of bone metabolism in postmenopausal women which is related with decreased bone mineral density. The current study aims to investigate the role of serum omentin-1and some bone metabolism markers in osteoporosis among postmenopausal Iraqi women. This study was performedin the Rheumatology and Rehabilitation Unit, Baghdad Teaching Hospital/ Baghdad medical city, during the period from November 2019 to July 2020 with a total of 60 postmenopausal women(30 with osteoporosis and 30 without osteoporosis), their ages ranged from 52 to 62 years. They were compared with 30 healthy premenopausal
