يهدف هذا البحث إلى معرفة أثر استخدام دورة التعلم في اكتساب المفاهيم الصرفية واستخلاصها لدى طالبات قسم اللغة العربية بكلية التربية للبنات وقد صيغت فرضيتان مفادهما أن ؛ 1- لا توجد فروق ذات دلالة إحصائية بين متوسط درجات طالبات المجموعة التجريبية اللاتي يدرسن المادة الصرفية في دورة التعلم ومتوسط درجات طالبات المجموعة الضابطة اللاتي يدرسن المادة الصرفية بالطريقة القياسية لاكتساب المفاهيم. 2- لا توجد فروق ذات دلالة إحصائية بين متوسط درجات طالبات المجموعة التجريبية اللاتي يدرسن المادة الصرفية في دورة التعلم ومتوسط درجات طالبات المجموعة الضابطة اللاتي يدرسن المادة الصرفية بالطريقة القياسية لاكتساب المفاهيم. وقد اختارت الباحثة عمدياً قسم اللغة العربية بكلية التربية للبنات والذي يضم خمسة أقسام للمرحلة الأولى وقد اختير القسم (ب) عشوائياً للمجموعة التجريبية بينما مثل القسم (أ) المجموعة الضابطة وبلغت العينة (60) طالبة (30 طالبة) في كل من القسمين وقد تمت معادلتها باستخدام اختبار (AL-Taitest) في المتغيرات الآتية (العمر الزمني ودرجات المادة الصرفية في امتحان الفصل الدراسي الأول) ومربع (X) ودرجة التصحيح (نعم) في التحصيل الدراسي للوالدين. حدد الباحث موضوعات المادة العلمية التي ستتم دراستها في سياق التجربة وهي (8) موضوعات وأعد خطط دراسية لعرضها على مجموعة من الخبراء والمختصين وفي ضوء آرائهم تم دراسة موضوعات البحث من قبل الباحث نفسه واعد اختبارا تاليا مكونا من (30) فقرة اختيارية من نوع الاختيار من متعدد وعرض على مجموعة من الخبراء والمختصين للتحقق من صدق الاختبار وتحليل فقرات الاختبار وحساب ثباته وطبق على عينة بلغت (100) طالب وطالبة في المرحلة الأولى من قسم اللغة العربية بكلية التربية / الجامعة المستنصرية وبعد تحليل نتائج الإجابات ومعالجتها إحصائيا باستخدام الأدوات الإحصائية المناسبة تبين أن فقرات الاختبار صادقة ولحساب ثبات الاختبار تم استخدام أسلوب التجزئة شبه بعد معالجة بياناته باستخدام معامل ارتباط بيرسون والذي صحح صيغة سبيرمان – براون ليصبح (0.86) وهو معامل ثبات وقد بلغت درجة ثبات الاختبار التحصيلي (جيد جداً) وبعد انتهاء التجربة التي استمرت (8) أسابيع تم تطبيق الاختبار التحصيلي على طلاب مجموعتي البحث وبعد تحليل نتائج الإجابات تبين وجود فروق ذات دلالة إحصائية بين متوسط الدرجات (اكتساب المفاهيم والتلقين) لصالح مجموعتي البحث التجريبية التي درست مادة الصرف باستخدام دورة التعلم وفي ضوء نتائج البحث استنتج الباحث أن استخدام دورة التعلم فعال في تلقين المفاهيم الصرفية المتوازنة باستخدام الطريقة القياسية التقليدية وأوصى الباحث بتنويع طرق التدريس المستخدمة في مادة الصرف مع الاهتمام باستخدام دورة التعلم واقترح إجراء دراسات مماثلة على مراحل دراسية أخرى وبين المقررات الدراسية الأخرى.
In the present work, the surface properties of mixed binary surfactants containing sodium dodecylbenzene sulfate (SDBS) and Tween 80 (TW80) surfactants in aqueous solutions were studied at temperature 293 K using surface tension measurements. The critical micelle concentration (cmc) magnitude for both individual surfactants and their mixtures were established the obtained results revealed that the magnitude of cmc of the mixtures are less than the magnitude of individual surfactants and decrease with the increase in Tween 80 percent in solution which indicate the nonideal mixing of the two surfactants. The values of molecular interaction parameters and the mole fraction of surfactants in the micelle (X1) were calculated

tendance générale qui traite les thèmes de l'absurde ,du néant et de la
question de la mort , on trouve son recueil "l'Exil et le Royaume" 1957
qui contient six nouvelles qui sont d'une invention moins épouvantable
(le Renégat , la Femme adultère , les Muets , le Pierre qui pousse , l'Hôte
et Jonas). Ces nouvelles , à l'exception du "Renégat" , ne provoquent pas
les questions philosophiques et dialectiques qui dominent la plupart des
oeuvres d'Albert Camus , Mais ces nouvelles traitent tout simplement la
question d'homme exilé dans son existence et sa recherche perpétuelle
de son royaume.
Abstract
This work involves the manufacturing of MAX phase materials include V2AlC and Cr2AlC using powder metallurgy as a new class of materials which characterized by regular crystals in lattice. Corrosion behavior of these materials was investigated by Potentiostat to estimate corrosion resistance and compared with the most resistant material represented by SS 316L. The experiments were carried out in 0.01N of NaOH solution at four temperatures in the range of 30–60oC. Polarization resistance values which calculated by Stern-Geary equation indicated that the MAX phase materials more resistant than SS 316L. Also cyclic polarization tests confirme

Five defferent discharges of emitter and five initial volumetric soil moisture contents were used ranged between field capacity and wilting point were utilized to simulate the wetting patterns. The simulation of the water flow from a single point emitter was completed by utilized HYDRUS-2D/3D software, version 2.05. Two methods were used in developing equations to predict the domains o
