...Show More Authors

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%).

...Show More Authors

 

This paper analyses the relationship between selected macroeconomic variables and gross domestic product (GDP) in Saudi Arabia for the period 1993-2019. Specifically, it measures the effects of interest rate, oil price, inflation rate, budget deficit and money supply on the GDP of Saudi Arabia. The method employs in this paper is based on a descriptive analysis approach and ARDL model through the Bounds testing approach to cointegration. The results of the research reveal that the budget deficit, oil price and money supply have positive significant effects on GDP, while other variables have no effects on GDP and turned out to be insignificant. The findings suggest that both fiscal and monetary policies should be fo

...Show More Authors

This study was conducted to estimate some heavy metals cadmium, lead, nickel and iron in 15 samples of Iraqi honey with 3 replicates for each sample which were collected from apiaries near potential contamination areas in five Iraqi governorates, including Baghdad, Karbala, Babylon, Diyala and Salah al-Din. The atomic absorption technique was used to estimate the concentrations of heavy metals, the results showed that there were significant differences at (P≤0.05) between the concentrations of these elements in the honey samples, the highest concentrations of cadmium 0.123 mg/kg were recorded in Baghdad, near the petrochemical production complex, lead 4.657 mg/kg and nickel 0.023 mg/kg in Babylon near the power plant, iron was

...Show More Authors

Trace Elements (Cd, Pb, Cu, Zn, Ni) level were examined in hair of donors from industrial areas, cities and village, and in permanent contact with a polluted workplace environment in lattakia. Hair sample were analyzed for their contents of the trace elements by inductivity coupled plasma- mass spectrometer (ICP- MS). It was found that the contents of (Cd, Pb, Cu, Zn, Ni) in the hair were significantly higher in the industrial areas and cities, while in the village had the lower concentration of elements. Correlation coefficients between the levels of the elements in hair found in this study showed that hair is a good indicator of Environmental Pollution.

The aim of this study is to investigate the existence of some heavy metals (lead, cadmium, chromium) in colored plastic table dishes and study the migration of these metals to the food meals and the affecting factors in migration , such as storage period and food temperature. Six kinds of colored plastic table dishes were collected from Baghdad markets. The heavy metals in table dishes and in the prepared food meals put in them were estimated using atomic absorption spectrophotometer (Shimadzu A5000). The results indicated the existence of lead in all samples (1.61_1.00 mg/ kg) and chromium in three samples (0.85_0.97 mg/ kg) while other samples are free of chromium, and cadmium.
