إن النجاح في أداء المتطلبات الفنية والخططية في أي من الألعاب ألرياضيه يستوجب امتلاك العناصر الاساسيه المتعلقة بطبيعة الاداء ونوع الفعالية الرياضية الممارسة , لذا فان اغلب الألعاب الرياضية تعتمد على مكونات ألقدره التوافقيه والادراكيه الحسيه بوصفها احد العناصر الاساسيه في المستويات العليا لما توفره من قاعدة اقتران للصفات البدنيه والحر كيه وقدرات أجهزة الجسم الوظيفية , وفقا للأسس المعتمدة في بناء مهاراته, وعليه فان الارتقاء في درجات الأداء لتلك المتطلبات لايتم بلوغه ,ما لم تتفاعل الخبرات السمعية والبصرية والحس حركية لتشكيل الإدراك الشامل والصحيح الذي يهيئ للاعبه السيطرة التامة على الإيقاع الحركي سواء كان ذلك في ديناميكية الحركات والمهارات لتؤدى بما يناسب متطلبات الأداء .لذا وجدت الباحثتان ضعف الاعتماد على المؤشرات للقدرة التوافقية والقدرات الإدراكية الحسية الحركية والاستناد إلى مستويات الاستعداد مؤشرا منذ بداية التعلم الحركي ومدى التقدم في المستوى مقارنة بباقي المؤشرات الأخرى التي يبنى عليها تعلم الطالبة وتطورها في مادة جمناستك الأجهزة, وهدفت الدراسة الى التعرف على العلاقة بين بعض قدرات الإدراك الحسي – حركي المكاني ومستوى تعلم بعض مهارات جمناستك الأجهزة . واستعمل المنهج الوصفي على طالبات المرحلة الثالثة بكلية التربية الرياضية للبنات- جامعة بغداد.والبالغ عددهن (87)طالبة. للفترة من 2-3 ولغاية 13-3-2008م , في قاعة الجمناستك بالكلية التربية الرياضية للبنات- جامعة بغداد. وبعد جمع النتائج وتحليلها وفق الحقيبة الاحصائية استنتجت الباحثتان ماياتي : - وجود علاقة ارتباط معنوية بين بعض قدرات الادراك الحس حركي ومستوى تعلم بعض مهارات جمناستك الاجهزة .
This study relates to synthesis of bentonite-supported iron/copper nanoparticles through the biosynthesis method using eucalyptus plant leaf extract, which were then named E-Fe/Cu@B-NPs. The synthesised E-Fe/Cu@B-NPs were examined by a set of experiments involving a heterogeneous Fenton-like process that removed direct blue 15 (DB15) dye from wastewater. The resultant E-Fe/Cu@B-NPs were characterised by scanning electron microscopy, Brunauer–Emmet–Teller analysis, zeta potential analysis, Fourier transform infrared spectroscopy and atomic force microscopy. The operating parameters in batch experiments were optimised using Box–Behnken design. These parameters were pH, hydrogen peroxide (H2O2

Silicoaluminophosphate (SAPO-11) was prepared using the hydrothermal method with a concentration of carbon nanotubes (CNT) of 0% and 7.5% at 190 °C crystallization temperature. The final molar composition of the as-prepared SAPO-11 was Al2O3: 0.93P2O5: 0.414SiO2. 4% MO/SAPO-11 was prepared using impregnation methods. The produced SAPO-11 was described using X-ray diffraction (XRD) and Brunauer-Emmet-Teller (N2 adsorption–desorption isotherms). It was found that the addition of CNT increased the crystallinity of SAPO-11. The results showed that the surface area of SAPO-11 cont

Show MoreThe present work aims to improve the flux of forward osmosis with the use of Thin Film Composite membrane by reducing the effect of polarization on draw solution (brine solution) side.This study was conducted in two parts. The first is under the effect of polarization in which the flux and the water permeability coefficient (A) were calculated. In the second part of the study the experiments were repeated using a circulating pump at various speeds to make turbulence and reduce the effect of polarization on the brine solution side.
A model capable of predicting water permeability coefficient has been derived, and this is given by the following equations:

The species of Opilio kakunini Snegovaya, Cokendolpher & Mozaffarian, 2018 was recorded for the first time in Iraq; as well as to four species belonging to this order which were recorded previously. In this paper, we added a new species to the checklist of Iraqi opilionid fauna with a description of the most important characteristics, along with genitalia, for both males and females are presented with digital photographs. Specimens of males and females were collected from Al- Rifai district northern of Dhi-Qar Province, southern of Iraq.
Biomass is a popular renewable carbon source because it has a lot of potential as a substitute for scarce fossil fuels and has been used to make essential compounds like 5-hydroxymethylfurfural (HMF). One of the main components of biomass, glucose, has been extensively studied as a precursor for the production of HMF. Several efforts have been made to find efficient and repeatable procedures for the synthesis of HMF, a chemical platform used in the manufacturing of fuels and other high-value compounds. Sulfonated graphite (SG) was produced from spent dry batteries and utilized as a catalyst to convert glucose to 5-hydroxymethylfurfural (HMF). Temperature, reaction time, and catalyst loading were the variables studied. When dimethyl sulfo
