Abstract: ان التاكل الداخلي في انابيب الصلب الكربوني الذي يحدث بوجود غاز ثاني اوكسيد الكربون يعتبر مشكلة جوهرية في صناعات النفط والغاز وهو يقترن دائما مع وجود الماء. ان احتمالية حدوث التاكل تزداد بصورة عامة مع تزايد نسبة الماء ومع زيادة مستوى الماء المنتج تزداد مع | Internal corrosion of carbon steel pipelines occurring in the presence of CO2 is a substantial problem in the oil and gas industries. It is always associated with the presence of free water. The likelihood of corrosion generally increases with the volume fraction of the water phase. As the produced water level increases, the corrosion rates of carbon steel increase very rapidly and causes damage of petroleum and gas pipelines. The present research work focuses on the investigating of the corrosion rate of carbon steel as flow line in crude oil production with CO2 content employing three Iraqi crude oil (Kirkuk crude oil, Halfaya crude oil, Rumalia crude oil) with different brine concentrations [1%NaCl, 2%NaCl, 3%NaCl]. Determining the corrosivity of Iraqi crude oil was studied for the first time. Experiments were performed in an autoclave test apparatus, crude oil - produced water mixtures, water cuts were (0, 10, 20, 30, 40, and 100%), and total volume of mixtures inside the autoclave was always kept at 100ml and temperature (20, 40, 60°C). For all experiments, CO2 partial pressure was maintained at (4 bar) and rotational speed (500 rpm).The corrosion rates were determined by the weight loss technique. The results revealed that the corrosion rates of carbon steel increased by increasing water cut and temperature, but decreases with increasing salt concentration for all types of crude oil. Results also indicated that different crude oil has significantly different effects on corrosion of carbon steel, with identical brine compositions. Therefore, Rumaila crude oil exhibits the highest corrosion rates and Kirkuk crude oil exhibits the lowest corrosion rates while Halfaya crude oil exhibits a moderate corrosion rates e.g. at 1% NaCl, 20% water cut, temperature 60°C, pressure 4bar, the corrosion rate of carbon steel in Rumaila crude oil is 0.9163mm/yr whereas it is 0.564 mm/yr and 0.705 mm/yr in Kirkuk crude oil and Halfaya crude oil respectively. The Corrosion Rate Break produced water level was determined from the experiments. These tests are employed to evaluate the requirements for corrosion inhibitor treatment. At 100% water cut (brine/CO2) the corrosion rates of carbon steel was the highest. The presence of crude oil decreases the corrosion rates e.g. at 1% NaCl,100% water cut(brine/CO2) the corrosion rate is 7.1197 mm/yr, whereas at 40% water cut/ Rumaila crude oil the corrosion rate is 1.4097 mm/yr.

Abstract: يعد التثقيف الصحي على انه وسيلة اعلامية لجميع الناس لغرض تشجيع وتغيير العادات الى مستوى صحي وصحيح ويمكن ان يعرف التثقيف الصحي بانه مساعدة فئات المجتمع للتخلص من الامراض ووقاية الناس بواسطة تغيير معتقداتهم وافكارهم وسلوكهم نحو الصحة الشخصية تهدف الدراسة ا | Health education is regarded as an informative process achieved for all the people to promote and change their personal habits towards more healthy and accurate , or it may be defined as ( assistance of all community from any disease occurrence with the prevention and protection by affecting their attitudes , believes and behaviors regarding the personal health. This study is an attempt to assess the current situation of primary health centers in Kirkuk city regarding the health educational programs and to assess the main health educational needs and achievements.It is a descriptive study including all the health centers in Kirkuk - district except ( 7 ) of them excluded due to bad security situation in the city and only (12) primary health care centers were conducted starting from the 1st of December / 2007 to the end of February / 2008 , through a questionnaire form which is designed. for follow up the health activities achievement which are adapted by Ministry of Health plan for health directorates and health centers.interviewed by the researcher.The doctors and health educators who were working in these centers were included with main concentration on the educational aspect regarding (teaching aids , records obstacles and educational room with its equipments ). The health centers were classified by health directorate into ( 3) main groups according to the presence of educational methods and equipments and these are : - The first group including (5) model health centers with full , and complete supplementation of educational needs of teaching aids while the second group includes (4 ) health centers with ordinary aids and the last group containing (3) centers with still the old fashion of teaching aids and methods Nearly half of model health centers having (Audio - visual ) methods (45%) but 66.8%) of them were well - prepared updated health educational records And ( 58 %) of the health educators preferring educational models +audio - visual methods and the main educational obstacles are inadequate staff with insufficient methods (85% ) while the best suitable suggestions for avoiding these are supplying these centers with perfect well trained staff and motivation (33%).and (71%) of them agreed with the negative role of health directorate.During the 3 months period before the study , the educational activities for both the health directorate and health centers were affected in December /2007 and became over planned in the other two months (January and February /2008). Lack of the adequate training staff assessing the health educational activities and deficiency in teaching aids and methods necessary for conducting the health programs. with more attention towards motivation aspect with the little time provided for singly health group education and inadequate supplementation of the necessary needs in each health center are the main conclude points in the study
