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.
In diabetes, impaired wound healing and other tissue abnormalities are considered major concerns. Many factorsaffect the time and quality of wound healing. One of the purposes of medical sciences is wound healing in a short time withreduced side effects. The herbal products are more precious in both prophylaxis as well as curative in delayed diabetic woundhealing activity when compared to synthetic drugs.A wide range of evidence has shown that capers plant possesses differentbiological effects, including antioxidant, anticancer and antibacterial effects. Phytochemical analysis shows thatC. spinosahashigh quantities of bioactive constituents, including polyphenolic compounds, which are responsible for its health-promotingeffects. The healing

Compounds of (ZnO)1-x(SnO 2 ) x were prepared with various proportions of tin oxide (SiO 2) (x = 0.0, 0.2, 0.4, 0.6, 0.8, 1.0) by mixing zinc oxide (ZnO) with highpurity tin oxide and then sintering the mixture in an oven at a temperature of 1000 °C for a period of 1 h. The resulting powders were ground and pressed into tablets of 1 cm diameter and 0.5 cm thickness. The properties of (ZnO) 1-x(SnO 2 ) x composites flms were prepared and studied as sensitive to the diferent gases NO2 and H2 S. Thin flms were prepared from (ZnO) 1-x(SnO 2 ) x via pulsed laser deposition method using glass and single crystal silicon for investigation the morphology and gas sensing properties with a thickness of 150 nm. The morphology examinat

Polycystic ovary syndrome (PCOS) is a complex endocrine–metabolic disorder characterized by hyperandrogenism, ovulatory dysfunction, insulin resistance, and chronic inflammation resulting in reproductive and metabolic complications. Traditional metformin therapy improves insulin sensitivity, while newer dual incretin agonists, such as tirzepatide, may offer broader metabolic and ovarian protection. The objective of this study is to investigate whether tirzepatide could alter hormonal parameters, metabolism, inflammation, and histopathology of a testosterone propionate–induced PCOS rat model compared with metformin. Thirty prepubertal female Wistar rats were divided into five groups (n = 6). PCOS was induced by testosterone propionate (1

Background: Blood group system and the ability to taste phenylthiocarbamide (PTC) are the most studied traits in human genetics which have been extensively used in describing genetic variations among human populations around the world that may had an effect on dental caries. The aims of present study were to investigate the caries experience among students with different bitter taste threshold in relation to blood type. Materials and Methods: The sample of present study includes dental students female aged19-21 years. The diagnosis of dental caries was done according to the criteria of Manjia et al, 1989 recording decayed lesion by severity (D1-4) MFS. Furthermore, bitter taste sensitivity was measured according to PTC (phenylthiocarbamid

Objectives: the study aims to assess nurses' practices toward chemotherapy-induced peripheral neuropathy (CIPN) for children at the hematology center, and to determine the effectiveness of the health education program on nurses' practices toward CIPN, and to find out the relationships between the effectiveness of Health education program and demographic characteristics of nurses.
Methodology: Use quasi-experimental design in the study (a design that divides the sample into two groups, a study group and a control group, with data collection in three stages). This study was conducted at a hematology center in Baghdad city for the period (from December 16th, 2019 to 8th May 202

In the present work radiography films have been used in evaluating the efficiency of using unsaturated polyester polymer reinforced with lead oxide (PbO) as shield material for medical x-ray devices, many parameters studied like concentration and thickness that they are increasing the attenuation of x-ray in them. The results show that the attenuation of X-ray increasing with concentration of reinforced material and with thickness, and the optical density decreases with increasing concentration from 0% to 50%, we chose 30% as suitable concentration to increase
