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.

Electronic properties including (bond length, energy gap, HOMO, LUMO and density of state) as well as spectroscopic properties such like infrared, Raman scattering, force constant, reduced mass and longitu- dinal optical mode as a function of frequency are based on size and concentration of the molecular and nanostructures of aluminum nitride ALN, boron nitride BN and AlxB7-XN7 as nanotubes has calculated using Ab –initio approximation method dependent on density functional theory and generalized gradient approximation. The geometrical structure are calculated by using Gauss view 05 as a complementary program. Shows the energy gap of ALN, BN and AlxB7-XN7 as a function of the total number of atoms , start from smallest molecule to reached

Background: Secretory Immunoglobulin A (SIgA) is a subclass of Immunoglobulin A (IgA), It is an antibody that plays an important role in mucosal immunity. It is the main immunoglobulin found in mucous secretions from mammary glands, tear glands and salivary glands, every pathologic process in the body involves the immune system, and periodontal inflammation is one of them and is not an exception. Material and methods: this study was consisted of 60 healthy male participants of an age ranged between (35-50) years old ; 25 of them with generalized moderate chronic periodontists(Clinical Attachment Loss equal to 3-4mm at ≥ 30% of the sites; 20 participants with plaque induced gingivitis and 15 participants had clinically healthy pe

In this paper we use the Markov Switching model to investigate the link between the level of Iraqi inflation and its uncertainty; forth period 1980-2010 we measure inflation uncertainty as the variance of unanticipated inflation. The results ensure there are a negative effect of inflation level on inflation uncertainty and all so there are a positive effect of inflation uncertainty on inflation level.

This is a study dedicated to explaining the conditions of the end of heaven, stage by stage; And to draw the final picture of it, through the facts of the Qur’an, and to make the contextual integration of the verses of the end of heaven, and their arrangement in an intentional arrangement, a path that guides us to knowing the integrated picture of it on the Day of Resurrection, according to scientific interpretation.
The importance and usefulness of the research lies in:
Extracting the order of the stages of the end of heaven, from its first state to its last, which came in separate verses of the Qur’an, each one of which was placed in a surah that was consistent w

To maintain a sustained competitive position in the contemporary environment of knowledge economy, organizations as an open social systems must have an ability to learn and know how to adapt to rapid changes in a proper fashion so that organizational objectives will be achieved efficiently and effectively. A multilevel approach is adopted proposing that organizational learning suffers from the lack of interest about the strategic competitive performance of the organization. This remains implicit almost in all models of organizational learning and there is little focus on how learning organizations achieve sustainable competitive advantage . A dynamic model that captures t
