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.
This article studied some linear and nonlinear optical characteristics of different pH solutions from anthocyanin dye extract at 180 oC from red cabbage. First, the linear spectral characteristics, including absorption and transmittance in the range 400-800 nm for anthocyanin solution 5% v/v with different pHs, were achieved utilizing a UV/VIS spectrophotometer. The experimental results reveal a shift in the absorption toward the longer wavelength direction as pH values increment. Then, the nonlinear features were measured using the Z-scan technique with a CW 532 nm laser to measure the nonlinear absorption coefficient through an open aperture. A close aperture (diameter 2 mm) calculates the nonlinear refractive index. The open Z-scan sh

The primary objective of this study is to examine the effects of a do-it-yourself (DIY) technique on the reading comprehension performance of fifth-grade students in preparatory schools. In order to accomplish the objective of this research, it is posited that a null hypothesis can be established, suggesting that there are no statistically significant disparities between the average scores of the experimental group, which is instructed using a do-it-yourself (DIY) strategy, and the control groups, which are instructed using a prescribed method, in terms of their reading comprehension attainment. Developing a pre- and post-achievement test. Both groups have been equalized in terms of characteristics such as parental educational leve

The research aims to know the extent of public exposure to specialized sports satellite channels, and what gratifications are achieved from them, and to reach scientific results that give an accurate description of exposure, motives and gratifications verified by that exposure, and the research objectives are summarized in the following:
- Revealing the habits and patterns of public exposure to specialized sports satelli
The members of the family of Eentrobacteriaceae harbour a gene cluster called polyketide synthase (pks) island. This cluster is responsible for the synthesis of the genotoxin colibactin that might have an important role in the induction of double-strand DNA breaks, leading to promote human colorectal cancer (CRC). Eleven out of the eighty eight isolates (12.5%) were pks+, distributed as 7 (8%) isolates of E. coli, 2 (2.25%) of K. pneumoniae and 2 (2.25%) of E. aerogenes. The cytotoxic effects of selected pks+ isolates (E. coli and E. aerogenes) on HeLa cells were represented by decreasing cell numbers and enlarged cell nuclei in comparison to the untreated cells. Cyt

An approach has been built to schedule the critical activities, by constructing some expressions based on the project lateness costs due to the interruption activities. Two simple example are presented to validate our approach.
