هدفت الدراسة الى التعرف على درجة اتخاذ القرار وعلاقتها ببعض المهارات الأساسية الهجومية بكرة السلة للطالبات ، اذ يعد اتخاذ القرار قدرة الفرد على التوصل لحل مشكلة اعتراضية أو موقف محير، وذلك باختيار حل من البدائل الموجودة أو المبتكرة، وهذا الاختيار يعتمد على المعلومات التي جمعها الفرد حول المشكلة وعلى القيم والعادات والخبرة والتعليم والمهارات الفردية وتمتاز لعبة كرة السلة بوجود الكثير من المواقف المتغيرة اثناء المباراة وهي عبارة عن صراع قرارات بين اللاعب المهاجم الذي يتخذ قرار لأنهاء الهجمة بشكل صحيح، واللاعب المدافع الذي يتوجب عليه اتخاذ قرار سريع لمواجهة المهاجم ومنعه من تنفيذ قراره وإحباط محاولة التنفيذ. ومن خلال خبرة الباحثتان فقد تبلورت هذه المشكلة في وجود قصور في اتخاذ القرار لطالبات المرحلة الرابعة والذي ينعكس على إدائهن في اللعب، وتكمن مشكلة البحث بالتساؤل الاتي: هل لاتخاذ القرار علاقة ببعض المهارات الأساسية الهجومية بكرة السلة للطالبات، اذ فرضت الباحثتان وجود علاقة ارتباط بين اتخاذ القرار وبعض المهارات الأساسية الهجومية بكرة السلة لطالبات، كما اعتمدت الباحثتان المنهج الوصفي بأسلوب الدراسة المسحية والعلاقات الارتباطية، وتمثل مجتمع البحث بطالبات المرحلة الرابعة في كلية التربية البدنية وعلوم الرياضة للبنات / جامعة بغداد للعام الدراسي 2022-2023 والبالغ عددهن (83) طالبة تم اختيار عينة عددها (30) طالبة، و (3) طالبات للتجربة الاستطلاعية من مجتمع البحث، وتم اعتماد مقياس اتخاذ القرار واختبارات المهارات الأساسية الهجومية بكرة السلة، كما تم استخراج النتائج باستخدام المعالجات الاحصائية المناسبة من برنامج (SPSS) وعرض النتائج وتحليلها ومناقشتها، في ضوء النتائج تم التوصل إلى صياغة الاستنتاجات: أن أغلب الطالبات يتمتعن بمستوى جيد من اتخاذ القرار والمهارات الأساسية الهجومية بكرة السلة، وهنالك علاقة طردية بين اتخاذ القرار والمهارات الأساسية الهجومية بكرة السلة للطالبات، كما توصي الباحثتان باجراء إجراء دراسة تتناول العلاقة بين متغيرات البحث الحالي وبعض المتغيرات الأخرى، كما تقترح الباحثتان إجراء دراسة مماثلة على فئة الطلاب واللاعبين المتقدمين والشباب والناشئين لمختلف الفعاليات.
Multiple eliminations (de-multiple) are one of seismic processing steps to remove their effects and delineate the correct primary refractors. Using normal move out to flatten primaries is the way to eliminate multiples through transforming these data to frequency-wavenumber domain. The flatten primaries are aligned with zero axis of the frequency-wavenumber domain and any other reflection types (multiples and random noise) are distributed elsewhere. Dip-filter is applied to pass the aligned data and reject others will separate primaries from multiple after transforming the data back from frequency-wavenumber domain to time-distance domain. For that, a suggested name for this technique as normal move out- frequency-wavenumber domain
... Show MoreThe paper is devoted to solve nth order linear delay integro-differential equations of convolution type (DIDE's-CT) using collocation method with the aid of B-spline functions. A new algorithm with the aid of Matlab language is derived to treat numerically three types (retarded, neutral and mixed) of nth order linear DIDE's-CT using B-spline functions and Weddle rule for calculating the required integrals for these equations. Comparison between approximated and exact results has been given in test examples with suitable graphing for every example for solving three types of linear DIDE's-CT of different orders for conciliated the accuracy of the results of the proposed method.
The essay discusses how different environmental factors affect plant growth by explaining how each factor affects the physiological processes within the plant. The essay begins by explaining the effect of temperature on plant growth, as high or low temperatures can significantly affect the rate of photosynthesis and lead to a reduction in water and nutrient absorption. It also discusses the light intensity impacting plants because the more appropriate the light intensity is, the more enhanced the plant's photosynthesis ability, and in the excess or insufficient light condition, the growth can be inhibited. Additionally, the article outlines the effect of water shortage on the plant because this leads to the closure of stomata to avoid water
... Show MoreThe 3D electro-Fenton technique is, due to its high efficiency, one of the technologies suggested to eliminate organic pollutants in wastewater. The type of particle electrode used in the 3D electro-Fenton process is one of the most crucial variables because of its effect on the formation of reactive species and the source of iron ions. The electrolytic cell in the current study consisted of graphite as an anode, carbon fiber (CF) modified with graphene as a cathode, and iron foam particles as a third electrode. A response surface methodology (RSM) approach was used to optimize the 3D electro-Fenton process. The RSM results revealed that the quadratic model has a high R2 of 99.05 %. At 4 g L-1 iron foam particles, time of 5 h, and

Octavius 4D-1500 phantom detector is a modern and qualified device for quality assurance procedure. This study aims to compare the common dosimetric criteria 3%/3 mm with 2%/2 mm for H&N plans for the IMRT technique. Twenty-five patients with head and neck (H&N) tumor were with 6MV x-ray photon beam using Monaco 5.1 treatment planning software and exported to Elekta synergy linear accelerator then tested for pretreatment verification study using Octavius 4D-1500 phantom detector. The difference between planned and measured dose were assessed by using local and global gamma index (GI) analysis method at

Show MoreThe goal of this investigation is to prepare zinc oxide (ZnO) nano-thin films by pulsed laser deposition (PLD) technique through Q-switching double frequency Nd:YAG laser (532 nm) wavelength, pulse frequency 6 Hz, and 300 mJ energy under vacuum conditions (10-3 torr) at room temperature. (ZnO) nano-thin films were deposited on glass substrates with different thickness of 300, 600 and 900 nm. ZnO films, were then annealed in air at a temperature of 500 °C for one hour. The results were compared with the researchers' previous theoretical study. The XRD analysis of ZnO nano-thin films indicated a hexagonal multi-crystalline wurtzite structure with preferential growth lines (100), (002), (101) for ZnO nano-thin films with different thi
