يتناول البحث التطور السياسي للدولة الحيثية خلال عهدي الدولة القديمة ثم الدولة الحديثة خلال الفترة الممتدة بين ق. 17 ق. م حتى ق. 13 ق. م .في محاولة لإبراز تأثير الصراعات الداخلية بين ملوكها على استقرار أوضاع تلك الدول بالإضافة الى إنعكاسات سياسة التوسع الخارجي الذي إنتهجته تلك الدول على أوضاع الشرق الأدنى القديم و إستمرارية دولة الحيثين نفسها خاصة إذا عرفنا أن مؤسسو تلك الدولة كانوا يسعون الى الهيمنة على شعوب أكثرا تحضرا منهم ، فماذا كان موقف الحضارات الاخرى المجاورة لهم منهم ؟ .

Speaking skill is one of the essential skills. It is considered the core skill in language learning, but Iraqi learners encounter difficulties when speaking English as a foreign language. It is common to note that despite years of learning English language, most learners are unable to speak fluently. Speaking skill is so complex that its development depends on practicing the target language by using interactive methods and classroom activities. English language teachers do not focus heavily on teaching speaking skill. Accordingly, learners have less exposure to the target language; therefore, there is a need to explore a new strategy that focuses on the practical aspect of teaching speaking skill.The present study aims at investigating empirically the Effect of Using Fan-N-Pick Strategy on EFL 5th Primary Students' Achievement in Speaking Skill.Fan-N-Pick which is a cooperative learning strategy that can be used in the classroom to foster and increase collaboration and interaction between pupils, review a concept, demonstrate understanding of content, share information about a topic and refine communication skills. In this strategy pupils will work in groups to answer questions cards. Each group member will have a different role, it's designed to assure that all pupils are participating rather than only allowing one pupil to respond at a time.To fulfill the aims of this study, the researcher has adopted the following null hypothesis: There is no statistically significant difference between the mean score of the pupils who are taught speaking skill according to Fan-N-Pick strategy and that of the pupils who are taught speaking skill according to traditional methods.The experiment lasted for five weeks during the academic year 2019/2020. It started on 2020/5/20 and ended on 2020/6/28. The researcher has adopted a (pre-post) test as an experimental design. The population of this study includes 5th-grade pupils of primary schools in the Babylon Governorate for the academic year 2019/2020. The sample comprises (40) pupils of Al -Aqsaa primary school for boys.This school has two 5th grade classes. Class (A) was chosen to represent the experimental group (20 pupils), whereas class (B) represented the control group (20 pupils). The experimental group received the treatment based on the Fan-N-Pick strategy and taught by the researcher herself in the second course of 2019/2020. Both groups were matched in terms of pupils' age (measured in months), the academic achievement of the parents, pupils' scores in the mid-year examination and the subjects' scores inthe pre -test. It is worth mentioning that the researcher herself has taught the two groups the same subject.It should be noted that this experiment was conducted using e-learning,because of the spread of the Covid 19 virus and school closures, where the researcher used one of the social media programs(Telegram) to communicate with the pupils.An oral speaking test is designed and used as the (pre-post) test and exposed to a jury of experts to verify their face validity. Additionally, thirty pupils are randomly selected from from Al-mustansraia primary school, the pupils represent the pilot study sample. With regards to reliability, a Pearson Correlation Coefficient reliability of (0.94) is found on the basis of the responses to the speaking skill test. The researcher has administered the test to both groups. After the treatment of the statistical data by using the T-Test of the two separated groups, the findings show significant statistical differences between the experimental group and the control one at the level of speaking skill test in favor of the experimental group in the post-test, which indicate that Fan-N-Pick strategy is more useful and efficient in teaching speaking skill than traditional ones. In the light of the study findings, some pedagogical recommendations and some suggestions for further studies are put forward.

La présente étude est consacrée à la simulation numérique des écoulements laminaires etturbulents incompressibles tridimensionnels et le transfert de chaleur d'un fluide traversant descoudes à 90° de section droite rectangulaire est entreprise en utilisant le code de calculFLUENT. Les simulations faites pour le régime laminaire et pour des rapports d’aspect de 0,3à 3, montrent que le champ dynamique et en particulier la vitesse longitudinale sontinfluencés par le rapport d’aspect. Pour le régime turbulent la simulation faite pour le rapportd’aspect 1. Le modèle de turbulence considéré pour cette étude est le modèle K-e standard,L’étude confirme l’existence de des écoulements secondaires à l'intérieur des coudes. Enfait, les écoulements au niveau des coudes sont caractérisés par la présence des cellulescontrarotatives responsables des brassages thermiques.

This experimental study was conducted using Rotating Cylinder Electrode (RCE) equipment available in the Engineering Research Center of the ResearchInstitute (RI),to investigate the effect of fluid hydrodynamics on Calcium Sulfate (CaSO4) scale deposition on Aluminum metal surfaces. It has been found that the deposition rate increasedas the speed of rotation increased. In addition, Scanning Electron Microscopic examinations were carried out to study the morphology and distribution of the CaSO4crystals deposited on the metal surface. At low speeds, the deposited scalewassoft and loose while at higher speedit wascompact and hard.Finally, based on the literature review, a comparison is presented of the CaSO4scale deposition on Aluminum against Stainless Steel(SS-316)at similar experimental parameters, such assolution concentration, speed of rotation and temperature
