أن كرة السلة بما تتضمنه من مهارات حركية متنوعة تتطلب من ممارسيها امتلاك عدد من القدرات الحركية الخاصة وبشكل خاص التوافق العضلي العصبي والرشاقة والقوة المميزة بالسرعة، فضلاعن قدرات الإدراك الحس- حركي (إدراك المكان وقوة دفع الكرة سواء بالطبطبة العالية أو الواطئة .... الخ ) لذا تكمن أهمية البحث في إيجاد الطرق والوسائل التي تطور قدرة الطالبة على إدراك قوة دفع الكرة والإحساس بها أثناء تعلم وتدريب الطبطبة بأنواعها بإدخال تمرينات إدراك قوة الذراع ومن ثم تأثيرها على مستوى أداء مهارة الطبطبة في كرة السلة . ومن خلال ملاحظة أداء الطالبات في دروس كرة السلة وجدنا ضعف في أداء مهارة الطبطبة سواء كان من الثبات أو من الحركة وعدم إدراك القوة اللازمة لأداء هذه المهارة بصورة صحيحة مما يؤدي إلى ارتباك في الأداء, ويدفع الطالبة إلى إعطاء قوة غير مناسبة وبالتالي ارتفاع الكرة إثناء الطبطبة إلى أعلى من مستوى الحوض أو إعطاء قوة غير كافية مما يؤدي انخفاض مستوى الطبطبة ، وهذا يرجع إلى قلة الإدراك والإحساس بالقوة المناسبة لدفع الكرة ، وهنا تكمن مشكلة البحث. وهدفت الدراسة إلى معرفة تأثير تمرينات إدراك قوة الذراع على مستوى أداء مهارة الطبطبة في كرة السلة . استخدم المنهج التجريبي على طالبات المرحلة الرابعة البالغ عددهم (25) طالبة قسموا على مجموعتين ( تجريبية وضابطة ) طبقت التجريبية تمرينات إدراك قوة الذراع , خلال الطبطبة (دفع الكرة) أدخلت في القسم الرئيسي الجانب التطبيقي من الدرس وبواقع ( 10 ) دقائق وعلى مدى 8 أسابيع . فاستنتج أن لتدريبات إدراك قوة الذراع تأثيراً ايجابياً في تطوير مهارة الطبطبة في كرة السلة لدى إفراد عينة البحث. وتوصي الباحثات بالتركيز على التمارين خاصة بادراك قوة الذراع خلال الدرس للارتقاء بمستوى أداء المهارة .
Random matrix theory is used to study the chaotic properties in nuclear energy spectrum of the 24Mg nucleus. The excitation energies (which are the main object of this study) are obtained via performing shell model calculations using the OXBASH computer code together with an effective interaction of Wildenthal (W) in the isospin formalism. The 24Mg nucleus is assumed to have an inert 16O core with 8 nucleons (4protons and 4neutrons) move in the 1d5/2, 2s1/2 and 1d3/2 orbitals. The spectral fluctuations are studied by two statistical measures: the nearest neighb
The aim of this study is to investigate the sedimentation environments and diagenetic processes of the Ibrahim Formation (Oligocene-early Miocene) in Zurbatiya, eastern Iraq. The Ibrahim Formation is comprised mostly of clayey micrite and skeletal grains composed of planktonic foraminifera, calcispheres, radiolaria, and benthic foraminifera. Glauconite and pyrite were documented in some restricted zones of this formation; they reflect quiet and reducing conditions. Radiolaria were identified in Late-Oligocene which was not known previously at this age regionally in carbonate formations of the Arabian Plate (AP). Mudstone, wackestone, and planktonic foraminiferal wackepackstone are the main microfacies that are affected by dissolutio

Thus, the aim of the research is to examine the level and dimensions of the emotional and existential psychological crisis at the sample of the study. It further aims to investigate the statistical significant difference at the level of (0.05) regarding the feeling of the existential psychological crisis among battered and non-battered women. To reveal the objectives of the study, the researcher applied the existential psychological crisis scale to a sample of (72) women, divided into two groups: (35) battered women, who have been chosen purposefully.

In vitro tests have been carried out to find out the efficacy of watery extracts of garlic Allium sativum and hot pepper Capsicum spp. against the trophozoites of Entamoeba histolytica cultivated in liver infusion agar media at 37 c . The doses of ( 0.01, 0.05 ,0.1, 0.5, 1 ml )of garlic and hot pepper watery extracts were added to certain number of E. histolotica trophozoits for exposure time of 24 hrs., the mortality percentage of trophozoites treated with garlic extract were ( 14.82 %, 31.05% ,46.16% , 64.29% , 92.7%) respectively , these percentages were very close to that obtained from the treatment with the hot peper extract which were (17.86%, 32% , 44% ,66.67% ,100%) respectively . Generally these results showed that the ga
