اثر استراتيجية المنطقة ذات الاهمية في تحصيل مادة الكيمياء عند طالبات الصف الثاني المتوسط
...Show More Authors

الملخص:- يهدف البحث الى معرفة اثر استراتيجية المنطقة ذات الاهمية في تحصيل مادة الكيمياء عند طالبات الصف الثاني المتوسط، ولتحقيق هدف البحث تم صياغة الفرضية الصفرية الاتية :- - لا يوجد فرق ذو دلالة احصائية عند مستوى دلالة (0.05 ) بين متوسط درجات طالبات المجموعة التجريبية اللاتي يدرسن وفقا لاستراتيجية المنطقة ذات الاهمية ومتوسط درجات طالبات المجموعة الضابطة اللاتي يدرسن وفق الطريقة الاعتيادية في تحصيل مادة الكيمياء. استعمل الباحث التصميم شبه التجريبي ذي الضبط الجزئي، وتحدد مجتمع البحث بطالبات الصف الثاني المتوسط لمدرسة ثانوية المحمودية للبنات التابعة لمديرية التربية العامة الكرخ الثانية للعام الدراسي ( 2025 – 2026 ). وبلغت عينة البحث ( 64 ) طالبة، بواقع ( 32 ) طالبة للمجموعة التجريبية درسن وفق استراتيجية المنطقة ذات الاهمية و( 32 ) طالبة للمجموعة الضابطة درسن وفق الطريقة الاعتيادية. كوفئت المجموعتان بالمتغيرات ( العمر الزمني، التحصيل الدراسي السابق لمادة العلوم، اختبار المعلومات السابقة) كما اعد الباحث مستلزمات البحث المتمثلة بـ ( تحديد المادة العلمية، صوغ الاغراض السلوكية، اعداد الخطط التدريسية). وتم بناء اداة البحث المتمثلة بناء اختبار تحصيلي تكون من ( 40 ) فقرة، اختيار من متعدد ذي اربع بدائل وتم حساب الثبات ومعامل التمييز والصعوبة وفعالية البدائل له. وبعد الانتهاء من تدريس المادة العلمية والذي استغرق الفصل الدراسي الاول للسنة الدراسية ( 2025 – 2026 ) بواقع حصة دراسية واحدة اسبوعيا لكل مجموعة وبعدها تم تطبيق الاختبار التحصيلي للمجموعتين وتم تفريغ البيانات ومعالجتها احصائيا باعتماد ( برنامج الحقيبة الاجتماعية SPSS )، واظهرت النتائج تفوق المجموعة التجريبية على المجموعة الضابطة في الاختبار التحصيلي. وفي ضوء هذه النتائج تم التوصل الى عدد من الاستنتاجات ووضع بعض التوصيات والمقترحات.

Laser-Induced Low-Resistance Ohmic Contacts on n-Si
...Show More Authors

In the present work, the feasibility of formation near-ideal ohmic behavior of In/n-Si contact efficiently by 300 s duration Nd:YAG pulsed laser processing has been recognized. Several laser pulses energy densities have been used, and the optimal energy density that gives best results is obtained. Topography of the irradiated region was extensively discussed and supported with micrographic illustrations to determine the surface condition that can play the important role in the ohmic contact quality. I-V characteristics in the forward and reverse bias and barrier height measurements have been studied for different irradiated samples to determine the laser energy density that gives best ohmic behavior. Comparing the current results with

Study on Flow Characteristics and Heat Transfer Behavior Around Different Geometrical Corrugated Extended Surfaces
...Show More Authors

Abstract

The current study presents numerical investigation of the fluid (air) flow characteristics and convection heat transfer around different corrugated surfaces geometry in the low Reynolds number region (Re<1000). The geometries are included wavy, triangle, and rectangular. The effect of different geometry parameters such as aspect ratio and number of cycles per unit length on flow field characteristics and heat transfer was estimated and compared with each other. The computerized fluid dynamics package (ANSYS 14) is used to simulate the flow field and heat transfer, solve the governing equations, and extract the results. It is found that the turbulence intensity for rectangular extended surface was larg

Abstract [email protected] Background: Acute Traumatic Stress Disorder (ATSD) might be complicated by Post Traumatic Stress Disorder (PTSD). Psychological First Aid (PFA) said to be helpful to reduce the possibility of reduction of ASD and PTSD symptoms. PFA is simple procedure to deliver help & support to victims, may be by some one close to him, quietly and professionally. Iraq has and is still experiencing, continuous traumatic stresses. ATSD is especially seen in war such as during the Gulf War, Embargo and nowadays under the current American occupation. With the extreme shortage of recourses and the given late priority to psychological problems and intervention have disastrous consequences on the psycho-social wellbeing of peop

Biology Textbook for Scientific Sixth Class in Iraq (A Comparative Study)
...Show More Authors

The textbook is the primary means of creativity and thinking, which has a major role in the development of the readership and mental abilities of the student. It is the basic tool in education in Iraq for the teacher and the student, which cannot be dispensed in any educational program. The current study aimed at the book of the biology of the sixth grade of science in Iraq (comparative study). It was compared to the book of biology for the twelve grade in the Kingdom of Jordan to identify the ratio of similarity and differences between them, in addition, to identify the weaknesses in the Iraq curriculum and developing appropriate solutions and suggestions to address them. The sample was represented with books of biology (six-science cla

...Show More Authors

The aim of this work was to develop and validate a rapid and low cost method for estimation of ibuprofen in pharmaceutical suspensions using Reverse-Phase High Performance Liquid Chromatography. The proposed method was conducted and validated according to International Conference on Harmonization (ICH) requirements. The chromatographic parameters were as follows: column of octyldecylsilyl C18 with dimensions (150 × 4.6) mm, mobile phase composed of acetonitrile with phosphoric acid with a ratio of 50 to 50 each using isocratic mode, flow rate of 1.5 mL/min and injection volume of 5 μL. The detection was carried out using UV detector at 220 nm. The method was validated and showed short retention time for ibuprofen peak at 7.651 min, wit
