The reality of social and technological change confirms that the classroom environment which prevailing present time is not suitable to emerge a new generation of people that have enough ability to face the contemporary challenges , this fact is as a result of education that is just focus on remembering and knowledge which is based on realities .but the real education should be based on understanding and thinking that is not reflected in our current educational reality . its noticeable that thinking is not take a pivotal role in curriculum this has been confirmed by a study ( al – musswi ,2011 ) ) and may be due all that these curriculum are still interested in quantity without concern in quality so its lost the spirit of renewal and c

إن تاريخ التعليم  في السنوات الأخيرة هو قصة تحكي تطور التعليم من بُعد والتعليم المفتوح وباختصار " الإنفتاح التعليمي " Opening up education؛فعلى مدى عقود قليلة  عملت  التكنولوجيا الحديثة مثل الكمبيوتر الشخصي ، والوسائط المتعددة التفاعلية ، والإنترنت باستمرار على توسيع فرص

Black slaves formed a section of the Murabit community, and they had an important role in wars and in settling battles to the Murabit state. Murabit state lords have depended on them in many scales such as, wars or within the community boarders

تعد الاسرة إحدى الوحدات الاجتماعية التي تهيئ الجيل المتطلع للحياة وهم الاطفال، وهي المهد الطبيعي للطبقة البشرية التي تباشر وتواجه اثراً هاماً تكوين الشخصية والسلوك الاجتماعي والخلقي ، وهي نقطة الوصول والتفاعل بين البيولوجي والاجتماعي وعنها ينشأ التفاعل النفساني ، وشبكة العلاقات الاسرية والعلاقات الخارجية المجتمعة . ومن خلال معاييرها وقيمها ينشأ السلوك سوياً كان ام مرضياً ( جانحاً ) ، ومشكلة جنوح الا

A series of 4-(methylsulfonyl)aniline derivatives were synthesized in order to obtain new compounds as a potential anti-inflammatory agents with expected selectivity against COX-2 enzyme. In vivo acute anti-inflammatory activity of the final compounds 11–14 was evaluated in rat using an egg-white induced edema model of inflammation in a dose equivalent to 3 mg/Kg of diclofenac sodium. All tested compounds produced significant reduction of paw edema with respect to the effect of propylene glycol 50% v/v (control group). Moreover, the activity of compounds 11 and 14 was significantly higher than that of diclofenac sodium (at 3 mg/Kg) in the 120–300 minute time interval, while compound 12 expressed a comparable effect to that of di

Companies compete greatly with each other today, so they need to focus on innovation to develop their products and make them competitive. Lean product development is the ideal way to develop product, foster innovation, maximize value, and reduce time. Set-Based Concurrent Engineering (SBCE) is an approved lean product improvement mechanism that builds on the creation of a number of alternative designs at the subsystem level. These designs are simultaneously improved and tested, and the weaker choices are removed gradually until the optimum solution is reached finally. SBCE implementations have been extensively performed in the automotive industry and there are a few case studies in the aerospace industry. This research describe the use o

In this paper, the speed control of the real DC motor is experimentally investigated using nonlinear PID neural network controller. As a simple and fast tuning algorithm, two optimization techniques are used; trial and error method and particle swarm optimization PSO algorithm in order to tune the nonlinear PID neural controller's parameters and to find best speed response of the DC motor. To save time in the real system, a Matlab simulation package is used to carry out these algorithms to tune and find the best values of the nonlinear PID parameters. Then these parameters are used in the designed real time nonlinear PID controller system based on LabVIEW package. Simulation and experimental results are compared with each other and showe

Amis: NAFLD is considered to be the most common cause of liver conditions worldwide. Also, it is a primary reason that leads to coronary artery diseases, limiting blood flow to the heart. Therefore, This study aimed to evaluate the serum level of Nesfatin-1 and its ability to indicate the prognosis of CAD in patients with NAFLD. Material & Methods: one-hundred eighty Individuals were enrolled in the study, including In both genders, blood was collected from each Individual and sent to the laboratory for biochemical tests. Findings: Data from the current study showed a significant increase in Nesfatin-1 in the CAD group and a significant decrease in Nesfatin-1 in the NAFLD group compared to the control group. In addition, there w

Recently, wireless charging based RF harvesting has interfered our lives [1] significantly through the different applications including biomedical, military, IoT, RF energy harvesting, IT-care, and RFID technologies. Wirelessly powered low energy devices become significantly essential for a wide spectrum of sensing applications [1]. Such devices require for low energy resources from sunlight, mechanical vibration, thermal gradients, convection flows or other forms of harvestable energy [2]. One of the emerging power extraction resources based on passive devices is harvesting radio frequency (RF) signals powers [3]–[5]. Such applications need devices that can be organized in very large numbers, so, making separate node battery impractical.
