لكل فعالية أو نشاط رياضي قدرات بدنية وحركيه وعقلية تختلف عن الأنشطة الأخرى تتفق مع طبيعة الأداء والقوانين الخاصة باللعبة، ولعبة الكرة الطائرة واحدة من الفعاليات التي تمتاز في جوانبها البدنية أو المهارية أو الخططية، وكما هو حال غالبية الالعاب الجماعية فان هناك تخصصات في هذه اللعبة تميز كل اللاعب وهي الأساس التي يبنى عليها الفريق والتي يعتمدها في الوصول إلى المستويات الرياضية العالية اذ ان التدريب التخصصي يعد الحجر الأساس الذي يبنى عليه التدريب؛ لذلك يجب مراعات الخصوصية الفردية في التدريب وفق الاختصاص لما لهذا من أهمية بالغة لدى لاعبي الكرة الطائرة، وعلى الرغم من توجه المدربين الى الجانب التخصصي لكل لاعب الا انه في الواقع لا يملك وسائل قياسية وتشخيصية متطورة تزوده بـبـيــانات دقيقة عن بعض القدرات الحركية عند لاعبيه والاعتماد حينئذٍ حتماً سيكون على الوسائل التقليدية للقياس والتشخيص الذاتي، التي لا تخلو من ثغرات والبعيدة كل البعد عن اساليب التقدم العلمي والتكنولوجي المعمول بها في اغلب دول العالم المتطور اذ أن التطور الذي شهدته لعبة الكرة الطائرة في النواحي الخططية جعل اللعبة تتجه نحو الخصوصية في الاداء فأصبح كل لاعب يتخصص بمجموعة مهارات محددة ومن اماكن او مراكز محددة في اللعب وحسب قدراته المهارية والبدنية والحركية والعقلية، وقد تحددت مشكلة البحث في معرفة الاختلاف النسبي في القدرات الحركية بين اللاعبين وعلى وفق تخصصهم، لمساعدة المدربين في جعل التدريب أكثر خصوصية وحسب المراكز عند وضع المناهج التدريبية. هدف البحث التعرف الى الفروق في مستوى بعض القدرات الحركية بين لاعبي الكرة الطائرة على وفق تخصصهم، أما فرض البحث هناك فروق ذات دلالة إحصائية في مستوى بعض القدرات الحركية بين لاعبي الكرة الطائرة على وفق تخصصهم، ولقد تم استخدام المنهج الوصفي لملاءمته مع طبيعة المشكلة، وتم تحديد مجتمع البحث وهم لاعبو أندية الدوري الممتاز العراقي بالكرة الطائرة والبالغ عددهم (140) لاعباً، أما عينة البحث فقد تكونت من أندية (غاز الجنوب، البحري، الشرطة، الصناعة) والبالغ عددهم (56) لاعباً وبنسبة 40 %، وتم أجراء التجربة الرئيسية للفترة من 2/2/2014 ولغاية 16/6/2014، ولقد أستنتج الباحثون أن هناك فروق وبنسب متفاوتة في مستوى بعض القدرات الحركية للاعبي الكرة الطائرة على وفق تخصصهم، وقد كانت أبرز التوصيات هي ضرورة إعطاء المدربين الوقت الكافي من الوحدة التدريبية للتدريب للقدرات الحركية وبحسب تخصص اللاعبين.
The present work determination astronomical ephemeris for satellites (determination position and velocity of satellite and orbital elements) in elliptical orbit where orbital elements in perigee point were known, therefore kepler's equation for elliptical orbit was solved by using Newton-Rephson method for numerical approximation.For the hyperbola orbit which represent orbit of shuttle (discovery join) far rang where solve kepler equation for hyperbola by use the same method pervious and then determination the coordinates of position and velocity for satellite or shuttle and the required programs are designing
Death is undoubtedly the theme of Don DeLillo’s White Noise. Murray Siskind, a College-on-the-Hill professor who is obsessed with the exploration and reinterpretation of American popular culture, talks about the Tibetan Book of the Dead, and the German mentor of Jack Gladney has been using the Egyptian Book of the Dead, translated into German. The core episode of the story is the Airborne Toxic Event, the associate of Heinrich (Jack’s teenage son), Orestes Mercator, dreams of becoming one of the great figures in the Guinness Book by challenging and confronting death by enclosing himself in a glass pen jam-packed with poisonous snakes, and Heinrich challenges an imprisoned mass murderer in a chess game. The scholarly expertise of Jack c

It aimed at controlling and exploiting several countries in Africa and Asia in addition to imposing their power and control on uninhabited islands. It received adherence and criticism as well. There also appeared activists and nations who stood against it and its practices. English novels discussed this notion greatly by pointing out the bad practices of the colonizers and how the colonized received them. This paper explores two narrative fictions that tackle the different aspects of the term. While Defoe, in Robinson Crusoe (1719), shows a colonial European figure who expresses his superiority, Wells, in “The Country of the Blind” (1904), deconstructs

this research aims it measure the technical efficiency of the branches of the General Company for Land Transport, That scattered geographically at country level, by Data Envelopment analysis (DEA) technique, as this technique relies on measuring the efficiency of a set of asymmetric Decision making units, which is one of the nonparametric mathematical methods for and application related to Linear Programming, and this is what helps the General Company for Land Transport to diagnose its branches performance by benchmarking with each other and determine the performance gap. The research found that there is variation in the level of efficiency in the company's branches
