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.
This paper describes a number of new interleaving strategies based on the golden section. The new interleavers are called golden relative prime interleavers, golden interleavers, and dithered golden interleavers. The latter two approaches involve sorting a real-valued vector derived from the golden section. Random and so-called “spread” interleavers are also considered. Turbo-code performance results are presented and compared for the various interleaving strategies. Of the interleavers considered, the dithered golden interleaver typically provides the best performance, especially for low code rates and large block sizes. The golden relative prime interleaver is shown to work surprisingly well for high puncture rates. These interleav

The analysis of this algorithm (MUSIC) with typical array antenna element ( ) shows that there are two false direction indication in the plan
aligned with the axis of the array. In this paper a suggested modification on array system is proposed by using two perpendiculars crossed dipole array antenna in spite of one array antenna. The suggested modification does not affect the AOA estimation algorithm. The simulation and results shows that the proposed solution overcomes the MUSIC problem without any effect on the performance of the system.
Quantitative analysis of human voice has been subject of interest and the subject gained momentum when human voice was identified as a modality for human authentication and identification. The main organ responsible for production of sound is larynx and the structure of larynx along with its physical properties and modes of vibration determine the nature and quality of sound produced. There has been lot of work from the point of view of fundamental frequency of sound and its characteristics. With the introduction of additional applications of human voice interest grew in other characteristics of sound and possibility of extracting useful features from human voice. We conducted a study using Fast Fourier Transform (FFT) technique to analy

The spectrum of the solution (Emission) was studied and found to be at 772 nm, several process parameters were such as concentration of TiO2 , and the effect of distance from nozzle tip to the grounded collector (gap distance). The result of the lower concentration of, the smaller the diameter of nanofiber is. Increasing the gap distance will affect nanofibers diameter.
This study aimed to determine the measurements and classification of Schneider membrane thickness correlated to age and sex factors using cone beam computed tomography (CBCT). Methods: The study included CBCT images for 100 maxillary sinuses of 50 consecutive patients, and the thickness of the maxillary sinus membrane (Schneiderian membrane) was measured in coronal view from the lowest point in the floor of the maxillary sinus to the highest point. The thickness of the Schneiderian membrane was classified into 4 types. Results: The study result revealed that out of the total cases, 45% of sinus membranes were classified as type 2, while only 10% were classified as type 4. The most frequent type of membrane thickness diagnosed in the age gro

storage period, this research has conducted on three species Eufcalyptus cammaldulensis,
Juglans regia, presence of some genus of fungi; Aspergillus, Penicillium,Botryoderma,
Chaetomium, Phoma, Cladosporium and Pacilomyces in different intensities.
The two fungi Aspergillus and Penicillium appeared more dominants than others, therefore
they were chosen for the pathogenicity test. The results showed that the two species of fungi
