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 .

The importance of this research has been to rationalize the cost of producing maize seeds through the followers of modern techniques and methods in agricultural activities such as genetic engineering for increasing production efficiency of maize seeds as well as the importance of calculating seed cost rationalization through the ABC system and thus rationalizing government spending. The research is based on one hypothesis in two ways that the use of genetic engineering on maize seeds works to: one - increase production efficiency of seeds and savings in agricultural inputs. 2. Rationalize the costs of examining and planting maize seeds. In order to calculate the costs will be based on the cost system based on activities ABC. The research

To evaluation the risk to the health status of Iraqi workers who work in the batteries industry, expression of three types of calmodulin related genes were examined. Blood samples were collected from worker working in Iraqi industry of batteries (located in Al-Waziriya), then RNAs extraction were done thereby gene expression for Calcium/Calmodulin- dependent protein kinase2 (CaMKK2), C-X-C Chemokine receptor 4 (CXCR4) and mitogen activated protein kinase kinase 6 (MAP2K6) was done for each sample by using RT-q

This paper represents a study of the effect of the soil type, the drilling parameters and the drilling tool properties on the dynamic vibrational behavior of the drilling rig and its assessment in the drilling system. So first, an experimental drilling rig was designed and constructed to embrace the numerical work.
The experimental work included implementation of the drill-string in different types of soil with different properties according to the difference in the grains size, at different rotational speeds (RPM), and different weights on bit (WOB) (Thrust force), in a way that allows establishing the charts that correlate the vibration acceleration, the rate of penetration (ROP), and the power

Show MoreVolcaniclastic rocks of Al Muqdadiya Formation (Pliocene) in Injana area, southern Hemrin anticline, NE of Iraq, were studied ( petrographically, physically, mineralogically and geochemically , as well as the engineering properties) to assess the suitability of volcaniclastic rocks to use them in industry as refractories. The results show that the physical and engineering properties change with the temperature change. The bulk density and the specific gravity increase by increasing temperature while the apparent porosity, water sorption and the linear shrinkage decrease. On the other hand the compressive strength increase by increasing temperature. The volcaniclastics have very low thermal conductivi

This research has been applied in the Rafidain Bank and its branches (Sunk, People, Al-Firdaws, and Alawiya); it used the questionnaire as a basic tool for collecting information. The sample was intentionality, which included all the heads of departments in the bank’s branches, which amounted to (33) workers, and data on the questionnaire paragraphs of 28 were processed using the SPSS V.23 and AMOS V.23).
