هدف البحث إلى إعداد تمرينات منطقة الشدة الثالثة للقوة المميزة بالسرعة للرجلين للاعبين الشباب بكرة القدم، والتعرف على تأثير تمرينات منطقة الشدة الثالثة للقوة المميزة بالسرعة للرجلين في السرعة الانتقالية وفي سرعة التهديف للاعبين الشباب بكرة القدم، وأفترض الباحث بأنه توجد فروق ذات دلالة إحصائية بين نتائج الاختبارات القبلية والبعدية لمجموعتي البحث التجريبية والضابطة لكل من السرعة الانتقالية وسرعة التهديف بكرة القدم، وتوجد فروق ذات دلالة إحصائية بين نتائج اختبارات مجموعتي البحث التجريبية والضابطة البعدية لكل من السرعة الانتقالية وسرعة التهديف بكرة القدم، واعتمد المنهج التجريبي ذا المجموعتين التجريبية والضابطة المتكافئة بالضبـط المحكـم بالاختبارين القبلي والبعدي على عينة اختيرت بالطريقة العمدية بلغت (22) لاعب ما نسبته (91.667%) من مجتمعهم المتمثل باللاعبين الشباب المتقدمين في نادي الصناعة بكرة القدم في الساحات المكشوفة البالغ عددهم (24) لاعب المستمرين في تدريباتهم للموسوم الرياضي (2023-2024)، وبعد تحديد الاختبارات تم اعداد (30) وحدة تدريبية لهذهِ التمرينات استمر التدريب بها لمدة (10) اسابيع متتالية بواقع (3) وحدات في الاسبوع، وبعد الانتهاء من التدريب تم معالجة البيانات بنظام (SPSS) لتكون الاستخلاصات والتطبيقات بأنه تساعد تمرينات منطقة الشدة الثالثة للقوة المميزة بالسرعة للرجلين في تحسين السرعة الانتقالية للرجلين، وفي تحسين سرعة التهديف للاعبين الشباب بكرة القدم، ومن الضروري عند إعداد وتطبيق تمرينات منطقة الشدة الثالثة للقوة المميزة بالسرعة للرجلين أن تراعي سرعة الانقباضات العضلية واتجاهها لدى للاعبي كرة القدم لتمكينهم من تخطي ظروف المباريات بأقصى سرعة، للحد من التأثيرات السلبية لتناقص السرعة الانتقالية للرجلين عند زيادة الصعوبات التدريبية لكل تمرين.
In this paper fractional Maxwell fluid equation has been solved. The solution is in the Mettag-Leffler form. For the corresponding solutions for ordinary Maxwell fluid are obtained as limiting case of general solutions. Finally, the effects of different parameters on the velocity and shear stress profile are analyzed through plotting the velocity and shear stress profile.
The aim of this work is to study the effect of diesel fuel percentage on the combustion processes in compression ignition engine using dual – fuel (diesel and LPG).
The brake thermal efficiency increased with the increase of diesel fuel rate at low loads, and decreased when load increased. To get sufficient operation in engine fueled with dual fuel, it required sufficient flow rate of diesel fuel, if the engine fueled with insufficient diesel fuel erratic operation with miss fire cycles presented.
Dual-fuel operation at part load showed higher specific fuel consumption than straight diesl operation. At full loads, brake specific fuel consumption of duel fuel engine approaches that for diesel fuel values.
Modern communication and media technology has pioneered new horizons and curried out deep changes in the various fields of social life, It effected enormously human communication as well.
