إن النجاح في أداء المتطلبات الفنية والخططية في أي من الألعاب ألرياضيه يستوجب امتلاك العناصر الاساسيه المتعلقة بطبيعة الاداء ونوع الفعالية الرياضية الممارسة , لذا فان اغلب الألعاب الرياضية تعتمد على مكونات ألقدره التوافقيه والادراكيه الحسيه بوصفها احد العناصر الاساسيه في المستويات العليا لما توفره من قاعدة اقتران للصفات البدنيه والحر كيه وقدرات أجهزة الجسم الوظيفية , وفقا للأسس المعتمدة في بناء مهاراته, وعليه فان الارتقاء في درجات الأداء لتلك المتطلبات لايتم بلوغه ,ما لم تتفاعل الخبرات السمعية والبصرية والحس حركية لتشكيل الإدراك الشامل والصحيح الذي يهيئ للاعبه السيطرة التامة على الإيقاع الحركي سواء كان ذلك في ديناميكية الحركات والمهارات لتؤدى بما يناسب متطلبات الأداء .لذا وجدت الباحثتان ضعف الاعتماد على المؤشرات للقدرة التوافقية والقدرات الإدراكية الحسية الحركية والاستناد إلى مستويات الاستعداد مؤشرا منذ بداية التعلم الحركي ومدى التقدم في المستوى مقارنة بباقي المؤشرات الأخرى التي يبنى عليها تعلم الطالبة وتطورها في مادة جمناستك الأجهزة, وهدفت الدراسة الى التعرف على العلاقة بين بعض قدرات الإدراك الحسي – حركي المكاني ومستوى تعلم بعض مهارات جمناستك الأجهزة . واستعمل المنهج الوصفي على طالبات المرحلة الثالثة بكلية التربية الرياضية للبنات- جامعة بغداد.والبالغ عددهن (87)طالبة. للفترة من 2-3 ولغاية 13-3-2008م , في قاعة الجمناستك بالكلية التربية الرياضية للبنات- جامعة بغداد. وبعد جمع النتائج وتحليلها وفق الحقيبة الاحصائية استنتجت الباحثتان ماياتي : - وجود علاقة ارتباط معنوية بين بعض قدرات الادراك الحس حركي ومستوى تعلم بعض مهارات جمناستك الاجهزة .

The experiment was carried out to study the effect of variety and gibberellic acid in concentration (0 and 50)mg.lat-1 and BL in five concentration (0, 0.50 ,1 ,2 and 3)mg.ltr-1 and their interaction in some chemical Characteristics and total chlorophyll for Dill plant . the experiment designed according Randomized Complete Block Design (RCBD) and three replicates per treatment, compared to the average using less significant difference at the level of probability (0.05) , the results showed the following:- The effect of brassinolide with it,s concentrations led to obtain a significant increase in all the studied characteristics, so the superiority of the concentration of 2 mg.L-1 of brassinolide in each of Ca, Mg,Fe, and total chlorophyll T

No matter how important the pillars of that system are, and through this research, we will learn how the political elites were able to crystallize this unique system, until it became one of the political systems that some countries seek to copy and apply its experience.
Summary The aim of this study is the evaluation the resistance of S. marcescence obtained from soil and water to metals chlorides (Zn+2, Hg+2, Fe+2, Al+3, and Pb+2). Four isolates, identified as Serratia marcescence and S. marcescena (S4) were selected for this study according to their resistance to five heavy metals. The ability of S. marcescena (S4) to grow in different concentrations of metals chloride (200-1200 µg/ml) was tested, the highest concentration that S. marcescence (S4) tolerate was 1000 µg/ml for Zn+2, Hg+2, Fe+2, AL+3, pb+2 and 300 µg/ml for Hg+2 through 24 hrs incubation at 37 Co. The effects of temperature and pH on bacteria growth during 72 hrs were also studied. S. marcescence (S4) was affected by ZnCl2, PbCl2, FeC12

Show MoreThis research seeks to study the role of proactive leadership as an essential element that helps all federations that lead the wheel of sports, including the Iraqi Handball Federation, so that it builds a correct environment that helps manage the organizational errors that the Handball Federation may fall into, and this in turn helps in early detection of errors and obstacles that may occur. It is likely that the Federation will fall into the process of managing and organizing the Iraqi Handball League, in addition to increasing the clubs’ ability to assist the Iraqi Handball Federation by being proactive so as not to make mistakes. The research community included the administrative bodies of the clubs participating in the Iraqi E

The research community was composed of 26 young volleyball players of Baghdad volleyball clubs. A total of 4 players were selected for the preliminary experiment, while 14 participants were recruited as the main sample for the study. In the present study, a set of resistance exercises were designed by the researchers for the volleyball players of the sample. Exercises were performed by the sample participants during the course of study. The biomechanical variables considered in the present study were: Preparation moment (shoulder joint angle, hip angle, knee joint angle), moment of pr

The diacid chlorides compounds [1-3] were prepared from the reaction of glutaric acid, adipic acid, terephthalic acid with thionyl chloride. Succinic acid reacted with ethanol to produce compound [4]. Compound [4] reacted with hydrazine hydrate to obtain succinic hydrazide [5].Compound [5] reaction with CS2 and KOH in absolute ethanol to produce compound [6].The polymers [7-12] have been created by reacting diacid chlorides compounds [1-3] with compound[5] or [6] in dry pyridine with some drops of DMF. The topology of produced compounds has characterized through their spectral and analytical data as in FT-IR spectra, Thermal analysis [DSC,
