هدفت الدراسة الى الاهتمام واستغلال ماهو جديد من تقنيات واجهزة حديثة في تعليم السباحة الحرة عن طريق توجيه الاطفال على تطوير مداركهم واستيعابهم بالتطور التكنولوجي الذي يتناوله العالم ،قامت الباحثتان باعداد منهج تعليمي باستخدام نظارة الواقع الافتراضي وذالك بتوفير بيئة مشابهة للبيئة الحقيقية تحاكي مدارك عقول الاطفال في عالم افتراضي لتتكون صورة كاملة عن مهارات السباحة الحرة ،ومن هنا اتت المشكلة نتيجة تعلق وولع اطفالها بشكل مبالغ فيه بالاجهزة والتقنيات الحديثة والمتطورة وقضاء اغلب اوقاتهم في استخدام التقنيات الحديثة والتي يصعب على الشخص البالغ استخدامها لكننا نجد الاطفال اكثر قدرة على التعامل معها لذالك لقد لاحظت الباحثتان هذه المشكلة وتبلورت الفكرة لحل هذه المشكلة في الاستخدام الجانب الايجابي لهذه التقنية لتحسين بعض القدرات الحركية وتعلم مهارات السباحة الحرة. واعتمد المنهج التجريبي بتصميم المجموعتين التجريبية والضابطة على عينة من اطفال الصف الاول الابتدائي بلغ (20) طفل واختيرت عمدية بنسبة (47.619%) من مجتمهم الاصلي المتمثل بطلاب الصف الاول الابتدائي في مدرسة العراق الدولية للعام الدراسي (2023-2024) المستمرين بالدوام المنتظم والحضوري ، اذ قسمت العينة الى مجموعتين تجريبية وضابطة ،وتم التجريب على اطفال المجموعة التجريبية لمدة (6) اسبوع متتالي بواقع وحدتين في الاسبوع ، وبعد الانتهاء تمت معالجة النتائج بنظام SPSS لتكون الاستنتاجات والتوصيات بانه من الممكن استخدام تقنية النظارة الذكية في الدروس العملية لتعلم مهارات السباحة الحرة للاطفال وان استخدام نظارة الواقع الافتراضي في دروس السباحة يساعد على تحسين بعض القدرات الحركية وتعلم السباحة الحرة للاطفال حيث تفوقت المجموعة التي استخدمت تقنية النظارة الذكية على الاطفال الذين تعلمو بدونها ، ومن الضروري زيادة الاهتمام بتعليم الاطفال على وفق تقنية نظارة الواقع الافتراضي التي وفرت لهم اثارة وتشويق في التعلم والبحث عن ماهو جديد يخدم عملية التعلم بشكل كبير. وهذا ما يحقق احد اهداف التنمية المستدامة للامم المتحدة في العراق (التعليم الجيد).
Bioaccumulation of heavy metals in the terrestrial invertebrates in Al-Jadriyia district Baghdad- Iraq were investigated. Forth terrestrial invertebrates snails, slug, isopods, and diplopods , were selected for this study. The results showed that all invertebrate groups have the ability in accumulate considerable amounts of heavy metals. Higher levels of zinc and copper were observed in the isopods specimens, it's about ( 60.50±0.58 ) and ( 96.00±0.58 ) ppm respectively , while higher levels of lead were observed in the diplopods specimens ,it's about ( 23.00±1.15 ) ppm ,but the higher levels of both iron and cadmium were observed in snail specimens , it's about ( 590.00±1.15 ) and ( 9.50±1.15 ) ppm respectively .but the
... Show MoreThe implementation of nanotechnology in all industries is one of most significant research fields. Nanoparticles have shown a promising application in subsurface fields. On the other hand, various surfactants have been used in the oil industry to reduce oil/water interfacial tension and also widely used to stabilize the nano-suspensions. The primary objective of this study was to investigate the improvements of surfactants ability in term of interfacial tension (γ) reduction utilizing addition of silicon dioxide nanoparticles at different temperatures and salinity. The pendant drop technique has been used to measure γ and electrical conductivity has been used to measure the critical micelle concentration (CMC). The synergistic effects of

Show MoreThe concept of Assemblage appeared obviously in Postdramatic works, where a character or a text may stand as an assemblage of potentialities in the sense that it signifies unidentified subjectivity. Assemblages are constituted essentially of heterogeneous elements yet fused without specific demarcations. In order to enjoy the desired productivity at a "smooth pace," the regularities of political and societal institutionalization are disseminated. To achieve this dissemination, Deleuze-Guattari suggest an unsatiated platform of a "Body without Organs' (BwO), where desire escapes identification. Martin Crimp (b. 1956) defines his off-stage characters in Attempts on Her Life (1997), Anne, or whatever the name is, as a 'BwO', upon which
... Show MoreIn the present study waste aluminium cans were recycled and converted to produce alumina catalyst. These cans contain more than 98% aluminum oxide in their structure and were successfully synthesized to produce nano sized gamma alumina under mild conditions. A comprehensive study was carried out in order to examine the effect of several important parameters on maximum yield of alumina that can be produced. These parameters were reactants mole ratios (1.5, 1.5, 2, 3, 4 and 5), sodium hydroxide concentrations (10, 20, 30, 40, 50 and 55%) and weights of aluminum cans (2, 4, 6, 8 and 10 g). The compositions of alumina solution were determined by Atomic absorption spectroscopy (AAS); and maximum yield of alumina solution was 96.3% obtain
... Show MoreWhen laser light incident on biological tissue, it is either reflected from the
surface of the tissue (e.g. the skin) or scattered inside the tissue or absorbed .The laser light will be
absorbed by water, hemoglobin and melanin. Absorption is also highly dependent on wave-length of
laser radiation. The absorbed light is converted into kinetic energy leading to laser effect that when
appropriately applied can produce reaction ranging from incision, vaporization to coagulation. Aim of
the study: To evaluate the efficiency of diode Laser 810 ± 20nm in treatment of oral lesions. Methods:
6 patients (2 females and 4 males) with different oral lesions were treated in the hospital of specialized
surgeries by the use of dio
In the present study the performance of drying process of dffirent solid materials by batch fluidized bed drying
under vacuum conditions was investigated. Three, different solid materials, namely; ion exchange resin-8528,
aspirin and paracetamol were used. The behavior of the drying curves as well as the rate of drying of these
materials had been studied. The experiments were caried out in a 0.0381 m column diameter fluidized by hot
air under yacuum conditions. Four variables affecting on the rate of drying were studied' these variables are
vacuum pressure (100 - 500 mm Hg), air temperature (303-323 K), particle size (0.3-0.8 mm) and initial
moisture content (0.35-0.55 g/g solid)-for resin and (0.1-0.2 g/g soltid) for a
