يهدف البحث الحالي إلى التحريّ عن صعوبات مادة الامريكيتين ، من وجهة نظر طالبات قسم الجغرافية في كلية التربية للبنات بجامعة بغداد ، تكوّن مجتمع البحث من طالبات المرحلة الثالثة و البالغ عددهن (230) طالبةً ، و لتحقيق هدف البحث اختارت الباحثة الاستبانة كأداةٍ للدراسة ؛ باعتبارها الأداة الأنسب في عملية جمع البيانات النهائية ، و الأكثر شيوعاً بين البحوث التربوية و النفسية ، فضلاً عن الاطلاع على الدراسات التربوية السابقة ذات العلاقة بموضوع البحث الحالي للإفادة منها في إعداد أداة البحث ، و في ضوء ذلك اختارت الباحثة عيّنةً استطلاعية بصورة عشوائية بلغ عددها (30) طالبة ، شكّلت نسبة (0.13) من المجتمع الأصلي ، و وجهت لهنَّ سؤالاً مفتوحاً بهدف التعرف على آرائهنَّ ، و الحصول على أكبر عدد من الصعوبات التدريسية من وجهة نظرهنَّ ، و بعد جمع البيانات الخاصة باستجابات الطالبات تم تصنيف الصعوبات الى خمسة مجالات رئيسة هي ( المادة العلمية- الطالبات- تدريسي المادة - طرائق و أساليب التدريس- أساليب التقويم) بواقع (6) فقرات لكلِّ مجال ، تم احتساب صدق فقراتها بعرضها على مجموعة من المحكّمين و المتخصصين في العلوم التربوية و النفسية و الجغرافية لتحديد مدى صلاحيتها، كما تم حساب ثباتها بطريقة (إعادة تطبيق الاختبار) على عيّنة استطلاعية بلغت (25) طالبة ، اختيرت بطريقة عشوائية شكّلت نسبة مقدرها (0.12) من المجتمع الأصلي المتبقي البالغ (200) طالبة ، و قد تم اعتماد (معامل ارتباط بيرسون) لحساب معامل الثبات ، و لمعرفة صعوبات تدريس مادة الامريكيتين من وجهة نظر الطالبات ، تم تطبيق أداة البحث على عيّنة البحث والبالغة (50) طالبة ، تم اختيارهن بطريقة عشوائية ، و باستخدام المنهج الوصفي التحليلي، و جمع البيانات و تحليلها إحصائياً باستعمال الوسائل الآتية (معادلة فيشر لحساب الوسط المرجح و الوزن المئوي لتحديد الوزن المئوي الخاص بفقرات مجالات الأداة ) ، و بعد ترتيب مجالات الأداة و فقراتها تنازلياً على وفق المعدل العام للوسط المرجح و النسبة المئوية توصلت النتائج الى : إنّ صعوبات مجال المادة العلمية كانت(أولاً) ، و صعوبات مجال طرائق و أساليب التدريس (ثانياً) ، و صعوبات مجال تدريسي المادة (ثالثاً) ،و صعوبات مجال أساليب التقويم (رابعاً) ، و صعوبات مجال الطالبات (خامساً) ، حيث تراوحت قيم أوساطها المرجحة بين (2.04) و(1.74) ، و أوزانها المئوية بين (68.08) و(58.08) على التوالي.
This work involves separating and studying the aminoacylase-1 (ACY1) of amniotic fluid from healthy pregnant, mainly one peak with higher activity has been isolated by DEAE-Cellulose ion exchange from the proteinous supernatant produced by deposition of proteins using ammonium sulfate (65%) after dialysis. The purification folds reaching to 19 folds also gave one protein peak when injected into the gel filtration column, a high ACY1 purity was obtained, with 38 folds of purification. It was found that the molecular weight of the isolated ACY1 was up to 46698 Dalton when using gel chromatography technique.The effect of ACY1 isolate was studied on rats with oxidative stress caused by lead acetate(LA) at 40 mg / kg body weight and compare

The aim of this study is to know the difference that will occur when heat treating the high strength aluminum alloys AA7075-T73 in a microwave furnace within different mediums (dry and acidic solution) at different times (30 and 60) minutes, on mechanical properties and fatigue life. The experimental results of microwave furnace heat energy showed that there were variations in the mechanical properties (ultimate stress, yielding stress, fatigue strength, fatigue life and hardness) with the variation in mediums and duration times when compared with samples without treatment. The ultimate stress, yielding stress and fatigue streng
