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.
A simple and rapid high performance liquid chromatographic with fluorescence detection method for the determination of the aflatoxin B1, B2, G1 and G2 in peanuts, rice and chilli was developed. The sample was extracted using acetonitrile:water (90:10, v/v%) and then purified by using ISOLUTE multimode solid phase extraction. After the pre-column derivatisation, the analytes were separated within 3.7 min using Chromolith performance RP-18e (100–4.6 mm) monolithic column. To assess the possible effects of endogenous components in the food items, matrix-matched calibration was used for the quantification and validation. The recoveries of aflatoxins that were spiked into food samples were 86.38–104.5% and RSDs were <4.4%. The method was

With the existing of toxicity and harvesting in predator and prey it consist of stage-structured. Near the positive equilibrium point of mathematical model on the Hopf bifurcation with particular emphasis it established. Near the equilibrium point E0 the transcritical bifurcation occurs it is described with analysis. And it shown that at equilibrium points E1 and E2 happened the occurrence of saddle-node bifurcation. At each point the pitch fork bifurcation occurrence is not happened.
Publications are generally considered an effective visual artistic means that addresses the recipient (the audience), with the functional, aesthetic and expressive dimensions they carry that contribute to spreading a diverse cultural awareness, especially those publications that are concerned with their media, promotional and organizational performance, as well as specific cultural events at specific times, in pursuit Access to renewable and elaborate designs to achieve the functional and aesthetic purpose, as the completed design and construction process is subject to many variations, whether this diversity is intellectual or technical, internal or external, and all of them may overlap to obtain a comprehensive system of artistic format
... Show MoreOryza sativa japonica (ofada rice) is largely grown in Aramoko, Abakaliki and Ofada are communities and consumed by both the poor and rich in Nigeria. A total of twenty ofada rice farmlands were identified in each study area and rice samples were randomly collected, thoroughly mixed to make a representative sample from each farmland. Soil samples were collected in each farm to a depth of 5-15cm from at least eight different points and thoroughly mixed together to form a representative sample. The samples were thereafter taken to the laboratory for preparation and spectroscopic analysis. A well-calibrated NaI(Tl) gamma-ray detector was used in spectrometric analysis of the samples and descriptive statistics was used to analyze th

Results of the study revealed some histological changes represented by aggregation of the lymphocytes around respiratory bronchioles of the lung. In the liver, the drug caused hepatocyte necrosis and infiltration of the lymphocytes. In Kidney, there are no histopathological modifications in the tissue after the animals treated with 10 mg\kg of Ivabradine. When the animals treated with Ivabradine drug at 20mg/kg of bw, dose showed vascular congestion between myocardial fibers of heart. Emphysematous c

Show MoreAn analytical and clinical study has been applied for measure the bioavailability of Zinc in serum of twenty adults healthy volunteers, using flame atomic absorption spectrophotometer (FAAS) at 213.9 nm. The calibration graph is linear in the ranges of 0.25-1.5 μg.mL-1 with correlation coefficient (R) 0.09996)μg.mL1-and molar absorpitivites 22957.76(L.mol1-cm-1.The concentration of Zinc determined in serum of all volunteers before and after administered orally a tablet of 50 mg zinc sulphate, produced by Samara drugs company (SDI). All data were subjected to statistical analysis by calculating accuracy, precision in addition to other parameters. The results indicate that the average maximum concentration (C-max ± SD) of blood zinc was 0.

Show MoreMyelosuppression is a serious disease that is related to the malfunction of blood cells production that leads to cytopenia which is the most serious hematologic toxicity of cancer chemotherapies including cyclophosphamide, which is a strong oxazaphosphorine [a nitrogen mustard alkylating agent] that can be used alone or combined with other chemotherapeutic agents for the treatment of different malignant diseases. It induces severe bone marrow suppression by damaging hematopoietic stem cells through the generation of oxidative stress.
