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.
The photodynamic inactivation against Methicillin-resistant Staphylococcus aureus using two different lasers, 532 nm diode pumped solid state laser (DPSS) in combination with safranin O and 650 nm diode laser in combination with methylene blue was investigated in the present work. A hundred swab samples were collected from patients with burn and wound infections admitted to two hospitals in Baghdad (Specialized Burns Hospital in Medical City and Al Imamein Al Jwadein Medical City Hospital) from December 2015 to February 2016 Antimicrobial susceptibility was performed by using Kirby- Bauer method. The irradiation experiments included four groups; a control group, a photosensitizer only group, a laser irradiation only group and a laser irr

The present study stresses the process of translating legislative terms used in Spanish wills into Arabic through high lightening the polysemy of such mentioned terms and explaining their use in other legislative grounds. Additionally, the present study elucidates, analyzes, underlines the difficulty and looks for the most appropriate procedures and techniques of translating some of the prominent inheritance expressions taking in account the legislative dif

Diazotization reaction between quinolin-2-ol and (2-chloro-1-(4-(N-(5-methylisoxazol-3-yl)sulfamoyl)phenyl)-2l4-diazyn-1-ium was carried out resulting in ligand-HL, this in turn reacted with the next metal ions (Ni2+, Pt4+, Pd2+, and Mn2+) forming stable complexes with unique geometries such as (tetrahedral for both Ni2+ and Mn2+, octahedral for Pt4+ and square planer for Pd2+ ). The creation of such complexes was detected by employing spectroscopic means involving ultraviolet-visible which proved the obtained geometries, fourier transfer proved the formation of azo group and the coordination with metal ion through it.

In this research, estimated the reliability of water system network in Baghdad was done. to assess its performance during a specific period. a fault tree through static and dynamic gates was belt and these gates represent logical relationships between the main events in the network and analyzed using dynamic Bayesian networks . As it has been applied Dynamic Bayesian networks estimate reliability by translating dynamic fault tree to Dynamic Bayesian networks and reliability of the system appreciated. As was the potential for the expense of each phase of the network for each gate . Because there are two parts to the Dynamic Bayesian networks and two part of gate (AND), which includes the three basic units of the

The problem when the response variable has one of two values either 0 ( no response) or one – with response which is called the logistic regression model.
We compare two methods Bayesian and . Then the results were compared using MSe criteria.
A simulation had been used to study the empirical behavior for the Logistic model , with different sample sizes and variances. The results using represent that the Bayesian method is better than the at small samples sizes.
