Abstract

determination of radon gas concentrations in multistory buildings and outdoor in the Karbala University campus (Karbala-Iraq) were carried out by using Solid-state nuclear track detector (CR-39).The detectors were distributed over 20places(14 indoor and others outdoor). The area of the study includes College of Medicine, College of Dentistry, College of Pharmacy, College of Sciences, student's residence and the Central Library. The dosimetric measurements were made over a period of 3 months.(from 15 September to 14 December 2012). After exposure, the detectors were etched in a (NaOH) solution of normality (6.25 N) at temperature of 70 oC for 3 hours. The tracks were counted by the microscope track-counting system. The indoor radon gas concentrations were found to vary from 41.881 ± 2.463Bq/m3 to 95.642 ± 5.730 Bq/m3 with an average value and standard deviation of 70.358 Bq/m3and14.367Bq/m3 respectively. The outdoor air radon concentrations are ranged from 25.134 ± 1.783Bq/m3 to 28.594 ± 2.854Bq/m3 with an average value of 26.974 Bq/m3and standard deviation 1.155 Bq/m3. In the survey of radon concentration in multistory buildings was observed that the upper floor have lower radon concentration than the ground floor. It has found that, in general, the radon level in lower floors is higher than that in upper ones in all buildings. The annual effective dose to the population from the inhalation of radon was also estimated and this varied from 1.056 ± 0.062mSv/ y to 2.412 ± 0.144mSv/ y, with an average of1.774 mSv/y and standard deviation is 0.362mSv/ y. The ratio between indoor and outdoor radon concentration (mean value) in this study was about 3.The radon concentrations were found to be lower than the higher level recommended by ICRP ( 200 Bq/m3) and thus are within safe limits.

Abstract

Research seeks to introduce the concept of knowledge management strategies, with the definition the most prominent examples of such strategies, as well as identifying important application in libraries university, through the statement of its role in the development of institutions, and then develop proposals to help in the deployment and use of this kind of knowledge for the development of university libraries Iraqi, and most of the recommendations that emerged from the study:1 - need to inform university departments of the importance of the application of knowledge management strategies and their role in the development of work in educational institutions, including the University Libraries, and the need to develop regulatory frameworks binding and specific to the application and one or more of these strategies in university libraries and follow-up project implementation of this strategy through the reports weekly or monthly issued by the library.2 - the need to choose library management strategy commensurate with its capabilities and resources, and consistent with the policy of the university and the Ministry of Higher Education and Scientific Research, and to be such a policy viable and planned accurately full joints of the goals and possibilities of the application, taking into account the periodic assessments of the stages of the application .

يسعى البحث الى التعريف بمفهوم استراتيجيات ادارة المعرفة، مع التعريف بابرز نماذج هذه الاستراتيجيات، فضلا عن تحديد أهمية تطبيقها في المكتبات الجامعية، من خلال بيان دورها في تطوير المؤسسات ، ومن ثم وضع مقترحات تساعد في نشر واستخدام هذا النوع من المعرفة لغرض تطوير اداء المكتبات الجامعية العراقية، ومن ابرز التوصيات التي خرجت بها الدراسة:1-ضرورة اعلام الادارات الجامعية لأهمية تطبيق استراتيجيات ادارة المعرفة ودورها في تطوير العمل في المؤسسات التعليمية وبضمنها المكتبات الجامعية، وضرورة وضع اطر تنظيميه ملزمة ومحددة لتطبيق واحدة او اكثر من هذه الاستراتيجيات في المكتبات الجامعية ومتابعة مشروع تطبيق هذه الاستراتيجية من خلال التقارير الاسبوعية او الشهرية التي تصدرها المكتبة.2-ضرورة اختيار ادارة المكتبة لاستراتيجية تتناسب مع امكاناتها ومواردها ، وبما يتفق مع سياسة الجامعة ووزارة التعليم العالي والبحث العلمي، وان تكون هذه السياسة قابلة للتطبيق ومخططة بشكل دقيق بكامل مفاصلها من اهداف وامكانات تطبيقها، ومراعاة عمليات التقييم الدورية لمراحل تطبيق هذه الاستراتيجية.

Abstract

AbstractThe present study aimed at detecting the side effect ofGlucophage on with diabetes with its both types , first and thesecond by applying it on the five tissue of white albino mice. Three doses were taken in this study of 50 100 and 150mg Kg for four weeks period . The results obtained showedthat the dose 150 mg had caused changes in the liver of themice , infiltration and congestion presence of edema fluidand changes in the cytoplasm of hepatocyte also occurred inthe liver of mice . The study came out with the result thatthe Glucophage drug should be taken in low doses that thepatients with diabetes . The study was carried out in thelaboratories of Karbala University .
