تكمن أهمية البحث بدراسة أهم المتغيرات البايوكينماتيكية المؤثرة في أنجاز فعالية قذف الثقل ومحاولة معرفة نسبة مساهمة كل متغير بايوكينماتيكي بدلالة إنجاز قذف الثقل للاعبين المتقدمين ، لعدم وجود أية دراسة على حد علم الباحثان قد تناولت المتغيرات البايوكينماتيكية ومحاولة معرفة نسب مساهمتها بدلالة إنجاز فعالية قذف الثقل ويهدف البحث إلى التعرف على أهم المتغيرات البايوكينماتيكية للاعبين المتقدمين بفعالية قذف الثقل ، والتعرف على نسبة مساهمة بعض المتغيرات البايوكينماتيكية بدلالة إنجاز فعالية قذف الثقل للاعبين المتقدمين ، وقد استخدم الباحثان المنهج الوصفي بالأسلوب المسحي على اللاعبين المتقدمين بقذف الثقل وعددهم (13) لاعباً ، وتم أختيار (8) متغيرات بايوكينماتيكية إضافة إلى إنجاز فعالية قذف الثقل ، وبعد معالجة البيانات وتفسيرها تم التوصل إلى الاستنتاجات الآتية : 1. تم التوصل لوجود نسبة مساهمة لمتغير (أرتفاع نقطة الورك في وقفة الاستعداد) كمؤشر بايوكينماتيكي مع إنجاز فعالية قذف الثقل للاعبين المتقدمين بمقدار (1.6%) . 2. تم التوصل لوجود نسبة مساهمة لمتغيري (أرتفاع نقطة الورك في وقفة الاستعداد وزاوية ميل الجذع في وقفة الاستعداد) كمؤشر بايوكينماتيكي مع إنجاز فعالية قذف الثقل للاعبين المتقدمين بمقدار (1.7%) . 3. تم التوصل لوجود نسبة مساهمة لمتغيرات (أرتفاع نقطة الورك في وقفة الاستعداد وزاوية ميل الجذع في وقفة الاستعداد وزمن الدوران الكلي) كمؤشر بايوكينماتيكي مع إنجاز فعالية قذف الثقل للاعبين المتقدمين بمقدار (1.7%) . 4. تم التوصل لوجود نسبة مساهمة لمتغيرات (أرتفاع نقطة الورك في وقفة الاستعداد وزاوية ميل الجذع في وقفة الاستعداد وزمن الدوران الكلي وزاوية الانطلاق) كمؤشر بايوكينماتيكي مع إنجاز فعالية قذف الثقل للاعبين المتقدمين بمقدار (3.2%) . 5. تم التوصل لوجود نسبة مساهمة لمتغيرات (أرتفاع نقطة الورك في وقفة الاستعداد وزاوية ميل الجذع في وقفة الاستعداد وزمن الدوران الكلي وزاوية الانطلاق وسرعة الانطلاق) كمؤشر بايوكينماتيكي مع إنجاز فعالية قذف الثقل للاعبين المتقدمين بمقدار (3.3%) . 6. تم التوصل لوجود نسبة مساهمة لمتغيرات (أرتفاع نقطة الورك في وقفة الاستعداد وزاوية ميل الجذع في وقفة الاستعداد وزمن الدوران الكلي وزاوية الانطلاق وسرعة الانطلاق وأرتفاع نقطة الانطلاق (الأداة)) كمؤشر بايوكينماتيكي مع إنجاز فعالية قذف الثقل للاعبين المتقدمين بمقدار (3.3%) . 7. تم التوصل لوجود نسبة مساهمة لمتغيرات (أرتفاع نقطة الورك في وقفة الاستعداد وزاوية ميل الجذع في وقفة الاستعداد وزمن الدوران الكلي وزاوية الانطلاق وسرعة الانطلاق وأرتفاع نقطة الانطلاق (الأداة) وزاوية ميل الجذع لحظة القذف) كمؤشر بايوكينماتيكي مع إنجاز فعالية قذف الثقل للاعبين المتقدمين بمقدار (3.3%) . 8. تم التوصل لوجود نسبة مساهمة لمتغيرات (أرتفاع نقطة الورك في وقفة الاستعداد وزاوية ميل الجذع في وقفة الاستعداد وزمن الدوران الكلي وزاوية الانطلاق وسرعة الانطلاق وأرتفاع نقطة الانطلاق (الأداة) وزاوية ميل الجذع لحظة القذف وزاوية مفصل الكتف لحظة القذف) كمؤشر بايوكينماتيكي مع إنجاز فعالية قذف الثقل للاعبين المتقدمين بمقدار (3.3%).
The Iranian nuclear program was one of the most prominent issues in the international arena, in light of Iran's insistence on using it in various ways, and according to international changes, it came under pressure from the American side to impose packages of sanctions, which continued to our time, as it went to Russia and China to gain support in developing its nuclear activities. And, by virtue of the common interests that are linked between them, Iran has received great support from the last two countries in all fields to reach the final agreement in 2015, regarding asserting the peace of these activities, in addition to lifting all restrictions represented in the previous sanctions according to the Security Council resolutions, Aldo

There is evidence suggesting that consuming high level s of protein may in fact have negative side effects for health. The current study included 29 young Iraqi building muscles in two different groups (taken and not protein supplements) (age range=17-31 years), the cases were selected from family, friends, college students, and Gyms), from November 2014 to March 2015. A careful history was obtained from each volunteer including age, duration of sports, type of supplements, and family history of diseases. Some biochemical parameters like (glucose, urea, uric acid, creatinine, bilirubin, serum protei

Leuconostoc bacteria was isolated from local pickled cabbage (Brassica oleracea capitata) and identified as Leuconostoc mesenteroides by morphology,biochemical and physiological. The local isolated L. mesenteroides bacteria under the optimal conditions of dextran production showed that, the highly production of dextran was 7.7g achieved by using a modified natural media comprised of 100ml whey, 10g refined sugar, 0.5g heated yeast extract, 0.01g CaCl2, 0.001g MgSO4, 0.001g MnCl2 and 0.001g NaCl at pH 6 and 25̊C for 24 hr of fermentation and by using 1ᵡ106 cell/ml as initial inoculums volume. Some applications in food technology (Ice cream, Loaf, Ketchup and Beef preservation) have been performed with processed dextran. The result
In the recent years, remote sensing applications have a great interest because it's offers many advantages, benefits and possibilities for the applications that using this concept, satellite it's one must important applications for remote sensing, it's provide us with multispectral images allow as study many problems like changing in ecological cover or biodiversity for earth surfers, and illustrated biological diversity of the studied areas by the presentation of the different areas of the scene taken depending on the length of the characteristic wave, Thresholding it's a common used operation for image segmentation, it's seek to extract a monochrome image from gray image by segment this image to two region (for

In recent years, it became an effective tool in drawing inferences about the complex data that we might come across in real life. Moreover, it can represent a tremendous confirmatory tool in classification observations based on similarities amongst them. In this paper, several mixture regression-based methods were conducted under the assumption that the data come from a finite number of components. A comparison of these methods has been made according to their results in estimating component parameters. Also, observation membership has been inferred and assessed for these methods. The results showed that the flexible mixture model outperformed the

The repeated measurement design is called a complete randomized block design for repeated measurement when the subject is given the all different treatments , in this case the subject is considered as a block . Many of nonparametric methods were considered like Friedman test (1937) and Koch test(1969) and Kepner&Robinson test(1988) when the assumption of normal distribution of the data is not satisfied .as well as F test when the assumptions of the analysis of variance is satisfied ,where the observations within blocks are assumed to be equally correlated . The purpose of this paper is to summarize the result of the simulation study for comparing these methods as well as present the suggested
