A mathematical model is developed which predicates the performance of cylindrical ion exchange bed involving comparing of axial dispersion model for cation exchange column with different assumption, this model permits the performance to predicate the residence time within the bed with the variance, axial dispersion and Pecklet No. to indicated deviation from plug flow model.

      Two type of systems are chosen for positive ions first with divalent ions (Ca⁺²) to exchange with resin of Na⁺¹form used as application in  water softener units and second with monovalent ions (Na⁺¹) to exchange with resin of H⁺¹ form used as application in deionize water units &n

استهدف البحث الحالي عزل بعض الجراثيم المرضية المشتركة وشملت Listeria monocytogenes و Salmonella spp. و Brucella abortus من أنسجة أعمار مختلفة من الأغنام العواسية المحلية . أخذت عينات من الكبد والكلى والدم ومن محتويات منتصف أمعاء ثلاث مجاميع عمرية من الأغنام العواسية من مجزرة الشعلة ببغداد شملت أعمار اقل من سنة واحدة وسنة إلى سنتين وأكثر من ثلاث سنوات . بينت النتائج عزل جراثيم Listeria monocytogenes  و Salmonella spp. و  Brucella abortus من كافة المجاميع

This study can be considered as un introduction to the idioms and the strategy about the productive partnership development connection, that helps the researcher and the organization in their work in to activate development and the natural sources,manegment,to improve the two sides active connected to the local society, and to use it as easier and smoother participation of the people who work in development field and the natural sources management research, That connection depends mostly upon the capability of researcher and the development worker to increase the ability of individual and local society to specify and analyzing their problems and to try solutions to make their life better with good income.

The growing international and local interest in environmental issues has influenced governmental stances and actions towards the public.
The research's main problem revolves around addressing a pivotal question: What are the levels of empowerment of public relations practition

The using of the parametric models and the subsequent estimation methods require the presence of many of the primary conditions to be met by those models to represent the population under study adequately, these prompting researchers to search for more flexible parametric models and these models were nonparametric, many researchers, are interested in the study of the function of permanence and its estimation methods, one of these non-parametric methods.

For work of purpose statistical inference parameters around the statistical distribution for life times which censored data , on the experimental section of this thesis has been the comparison of non-parametric methods of permanence function, the existence
