knowledge management and managers have a primary school principals from the standpoint of their assistants M . Dr. Suad Vegetables Abbas Research problem: The administration school require a leader administratively The efficiency and skills of management and knowledge to make it effective in the administration follows the scientific method and knowledge of those who through administrative methods emanating from the trends of modern management in the management of educational , as well as the presence of the leaders of effective management has the knowledge and know-how administrative work and how to deal with others and investment optimized for all of the resources available through the future capable of Orientalism to the extent that our educational institutions up to success and excellence and define the research problem the following question : Q : What is knowledge management and managers have a primary school principals from the standpoint of their assistants. The importance of research : The knowledge management today area later that drew the attention of specialists since become an urgent need for educational institutions after the trend witnessed in communities around knowledge by adopting methods and modern techniques to modify its behavior in the management of the operations of the renewal of knowledge and formulation , generation , storage and application , so it has become an urgent need to leaders are characterized by the experience and the knowledge and skills appropriate for the development of performance and excellence , as well as the knowledge and ability to take responsibility and to adapt to everything new and sophisticated to do the necessary leadership , especially with the growth and development of enterprises and the complexity of their roles . Research objectives: Current research aims to identify : 1 - Knowledge management at the orbital principals primary from the standpoint of their assistants . 2 - Differences of statistical significance in the management of knowledge among school principals variable depending on sex. 3 - Differences of statistical significance in the management of knowledge among school principals depending on length of service. Find limits : - Human border : aide primary orbital and collaborations in the General Directorate for Educational Baghdad Karkh second. - Temporal boundaries : the academic year 2012 - 2013 Research methodology and procedures : research methodology was followed in the current search descriptive - The research community : The research community ( 1.64 ) , Deputy Associate , at ( 434) Associate (630 ) help . - Sample search: to determine the percentage (10%) of the total community , as the number of members of the sample ( 106 ) by ( 43 ) and Associate ( 63 ) help . - Search tool : The tool was built to look after you follow the steps in terms of scientific exploratory study as well as access to previous studies and then presented to the expert specialists for honesty virtual instrument consisted of ( 34) paragraph. After the amendment became finalized tool consists of (34) paragraph so that you do not delete any paragraph , has been using the pentatonic scale . Statistical methods : The researcher used the following statistical methods ( arithmetic mean , standard deviation, Ca 2 box , the Pearson correlation coefficient , test Altaúa for a single sample, test Altaúa for two samples ) . Conclusions : In the light of the results was reached the following conclusions : 1 - Weakness in the possession of school principals to knowledge management skill in the General Directorate for Educational Baghdad's Karkh second. 2 - There is no statistically significant differences in knowledge management by variable sex . 3 - The presence of statistically significant differences in knowledge management depending on the length of service for the benefit of the owners of the service more than 10 years . Recommendations: 1 - Develop objective criteria for the selection of school principals based competence and experience and academic achievement . 2 - Activation of in - service training courses for school administrators in accordance with educational developments and trends of modern management . 3 - To benefit from the experiences of excellence in educational institutions.

Animal fats are a good, promising and ethical alternative source for biodiesel production, but they need more complex treatments than vegetable oils. Iraqi butchery plants waste fats (sheep fat) which are suggested as feedstock to produce biodiesel. This type of fat contains a large quantity of free fatty acids (FFAs) (acid number 49.13 mg KOH/g of fat). The direct transesterification of such fats produce high amount of soap instead of desired biodiesel, so a pre-treatment step (to reduce FFAs) is necessary before transesterification. This step was done by esterification of the free fatty acids in the fat by adding ethanol and using 1% acid catalyst (H2SO4) for 30 minutes. The results showed that the acid number of sheep fat after pre-tr

It is a very necessary enzyme to protect the cell from oxidative detriment by reactive oxygen species (ROS). The aim of this study is the partial purification and characterization of Catalase enzyme from Banana peels. In this study, fresh banana peels are treated with 70 % ethanol ,further separated with chloroform ,water and ethyl acetate respectively .The supernatant of the enzymatic sample which is treated with chloroform is loaded into gel filtration column with Sephadex G-100 (1.0 x 90 cm) equilibrated with pH7 buffer media (phosphate buffer 0.1 M).

The study aims to identify the role of family in inculcating the moral values of voluntary work among adults, as it constitutes the basic social institution that is responsible for raising and control children. It has regarded as the first phase of constituting societies, where family plays a significant role in changing the behavior of individuals positively or negatively through provided patterns. The moral values act as organizer of human relationship in which misusing of these values would affect the interaction between people. This study focuses on how to employ the moral values in voluntary work as a civilized behavior helps in developing and strengthening societies. The researcher adopted the analytical-descriptive approach as mor

- Identifying the statistically significant differences in the visual culture skills of students of the College of Education for Pure Sciences / Ibn Al-Haytham according to the gender variable.
And the descriptive approach was used, due to its relevance to the nature of the research objective.
To verify this, the visual culture skills test consisted of (22) items of the multiple choice type, where the (Koder Richardson 20) equation was applied to calculate the stability of the visual culture skills test. For the skill of writing
The increasing use of polymeric materials in the daily life, leads to challenges in the processing industry to deliver high performance materials with affordable terms. However, new processing techniques lead to high costs. In order to reduce processing costs it is necessary to understand the non-Newtonian behavior of the polymers in their molten state to be able to simulate the processes before the construction of the plants starts. Here the shear thinning behavior of the viscosity of polymeric melts is essential. Thus, this paper deals with the experimental investigation of the thermo-rheological behavior of the viscosity of one of the most used polymers (Polypropylene) over a wide range of temperatures and shear rates. Furthermo

The research revealed that the location of forming the meander was associated closely with the scale structural composition of the bank materials from which the first stage of forming the curved stream, for the inhomogeneous or non-identical opposite banks in their scale structural composition saw an activity of differential corrosion, while the homogeneous and identical opposite banks in their scale structural composition saw an identical corrosion activity in its intensity at both
Abstract This study seeks to deal academically with how the EU treats clandestine immigration, through adopting a purley security approach, based on the European understanding of security threats posed to the security of communities and States in EU at all levels. So they agreed upon criminalizing this threat within the bloc while using repressive tools and steps to limit illegal immigrants flow to European territories. Accordingly, the EU gave the phenomen a security character. So it takes it from low politics level , that of employment and economic field to that of high politics, as a new security problem lying within a new security language embraced by ruling European elites, in other words EU touched on this issue as a speech act emp
