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.
This research develops a new method based on spectral indices and random forest classifier to detect paddy rice areas and then assess their distributions regarding to urban areas. The classification will be conducted on Landsat OLI images and Landsat OLI/Sentinel 1 SAR data. Consequently, developing a new spectral index by analyzing the relative importance of Landsat bands will be calculated by the random forest. The new spectral index has improved depending on the most three important bands, then two additional indices including the normalized difference vegetation index (NDVI), and standardized difference built-up index (NDBI) have been used to extract paddy rice fields from the data. Several experiments being

Show MoreObjective: To assess the impact of anxiety and stress during pregnancy upon neonatal outcome Methodology: A descriptive purposive study was used to assess the impact of anxiety and stress during pregnancy upon neonatal outcome. The study was conducted from (22nd \ September \ 2020 to 15th \ February \ 2021). A non-probability sample (purposive sample) was selected from 100 women. Data were collected through an interview with the mother in the counseling clinic, during the third trimester of pregnancy, as well as after childbirth in the labour wards to assess the outcome of pregnancy. Data were analyzed through descriptive statistics (frequency and percentages). Results: The most important thing observed in this study was the n
... Show MoreWireless sensor networks (WSNs) are emerging in various application like military, area monitoring, health monitoring, industry monitoring and many more. The challenges of the successful WSN application are the energy consumption problem. since the small, portable batteries integrated into the sensor chips cannot be re-charged easily from an economical point of view. This work focusses on prolonging the network lifetime of WSNs by reducing and balancing energy consumption during routing process from hop number point of view. In this paper, performance simulation was done between two types of protocols LEACH that uses single hop path and MODLEACH that uses multi hop path by using Intel Care i3 CPU (2.13GHz) laptop with MATLAB (R2014a). Th
... Show MoreIn this paper, a theoretical study of the energy spectra and the heat capacity of one electron quantum dot with Gaussian Confinement in an external magnetic field are presented. Using the exact diagonalization technique, the Hamiltonian of the Gaussian Quantum Dot (GQD) including the electron spin is solved. All the elements in the energy matrix are found in closed form. The eigenenergies of the electron were displayed as a function of magnetic field, Gaussian confinement potential depth and quantum dot size. Explanations to the behavior of the quantum dot heat capacity curve, as a function of external applied magnetic field and temperature, are presented.
Objectives of this project were to study the effect of 60% crude alcoholic extract of the seeds of cyperus esculentuson induced endometritis in the mice . The plant of cyperus esculentuswas extracted by preparing Alcoholic extract 60% . One hundred microliters of saline containing Escherichia coli (104cfu) was used to induce endometritis, by a single intracervicallyinjection, and endometritis developed after 2 days from injection. The mice were divided into five groups, The first group were treated with alcoholic extract of cyperus esculentusextract 150mg/kg body weight, the second group was treated with a daily 3mg per kg body weight of gentamicin given intra peritoneal,The third group was treated by 75mg/kg of cyperus esculentusextract an
... Show MoreRock failure during drilling is an important problem to be solved in petroleum technology. one of the most causes of rock failure is shale chemical interaction with drilling fluids. This interaction is changing the shale strength as well as its pore pressure relatively near the wellbore wall. In several oilfields in southern Iraq, drilling through the Tanuma formation is known as the most challenging operation due to its unstable behavior. Understanding the chemical reactions between shale and drilling fluid is determined by examining the features of shale and its behavior with drilling mud. Chemical interactions must be mitigated by the selection of suitable drilling mud with effective chemical additives. This study is describing t
... Show MoreThe technique of plant tissue culture has been used to In vitro micropropagation of Spilanthes acmella (L.) Murr. It is an ornamental and medicinal plant not cultivated in Iraq. Seeds were sterilized and cultuared on full strength Murashige and Skoog medium(1962)(MS). Naphthalene acetic acid (NAA), 6- furfuryl aminopurine (Kin.) growth regulators were used at the Initiation stage.The combination between IAA and Kin. was used in multiplication stage. IAA was used for rooting the shoots. Results showed that 1.5% sodium hypochlorite for 15 min was very effective for disinfecting and survival. Nodes exhibited relatively highest response as compared with apical meristems and leaflets culture. Supplying the culture medium with 1 mg/L.
