قال احد المربين ( أعطوني طفولة سعيدة ممتلئة وخذوا شباباً ناضجاً سليماً) ويعني بالطفولة السعيدة تلك الطفولة المشبعة بالحب والحنان وتلبية الحاجات المهمة للطفل حيث يتعلم الطفل من احضان العائلة بعض النواهي والاوامر حتى اذا اتسعت دائرة معارفه شملت الرفقة والعصبة حيث يبدأ الطفل بالتحرر شيئاً فشيئأ من الضوابط العائلية وينتقل مركز ولائه واخلاصه من العائلة الى العصبية وكلما تتوسع علاقات الطفل تزداد خبراته وت

مع انتشار برامج تلفزيون الواقع في العالم الغربي بصورة خاصة وباقي دول العالم بصورة عامة، ومع استعداد شبكات الانتاج لأنتاج المزيد منها بسبب الارباح الهائلة التي تجنيها من جهة، وانخفاض اجور انتاجها من جهة اخرى. فضلا عن رغبة الالاف من الاشخاص للمشاركة فيها (طمعا في الشهرة وكسب الجوائز)، عمدت هذه الشبكات الى صياغة عقود الاشتراك في هذه البرامج بصورة طويلة جدا، وبلغة نموذجية معقدة يصعب على الاشخاص العاديين فهمها، ت

تقوم القواعد القانونية اليوم بتنظيم معظم الروابط الاجتماعية وترسم حدودها وأثارها، ومنها الروابط العقدية، ولان تلك القواعد تمثل انعكاسا لحاجات المجتمع فيفترض أن يتطابق السلوك الإنساني والذي يعد "التصرف العقدي" احد ابرز صوره مع تلك القواعد تلقائيا، ومع ذلك يمكن أن يحدث إشكال أو اختلال في هذا السلوك، فيتطلب الأمر معالجته من طرف آخر حيادي، ليست له علاقة بأي من أطرافه الأخرى، وعلى أن يتسم بصفات معينة تستلزمها طب

Computer programs are works of importance of trade, scientific and practical, which is one of the key imports of industrialized countries such as the United States. Historically, computer programs have been found in commercial use since the sixties of the last century where the value is increasing day after day. This shows the urgent need to use them in our personal lives, let alone use in our business. However, it was during our study in the UK, I did not find what refers to determining what computer programs virtually, either through judicial decisions or legally, through legislation, both in common law countries that pursue curriculu Anglo-American system such as the law of England, and the U.S. or countries that pursue the curricu-lu

To develop a petrol engine so that it works under the bi-engine pattern (producer gas-petrol) without any additional engine modifications, a single-point injection method inside the intake manifold is a simple and inexpensive method. Still, it leads to poor mixing performance between the air and producer gas. This deficiency can cause unsatisfactory engine performance and high exhaust emissions. In order to improve the mixing inside the intake manifold, nine separate cases were modelled to evaluate the impact of the position and angle orientation inside the intake manifold on the uniformity and spread of the mixture under AFR=2.07. A petrol engine (1.6 L), the maximum engine speed (8000 rpm), and bi-engine mode (petrol-producer ga

Background: The study aim was to evaluate thermocycling effect on microleakage of occlusal and cervical margins of MOD cavity filled with bulk filled composites in comparison to incrementally placed nanohybrid composite and to evaluate the difference in microleakage between enamel and dentin margins for the three materials groups. Materials and method: Forty eight maxillary first premolars were prepared with MOD cavities. Samples were divided into three groups of sixteen teeth according to material used: Grandio: Grandio. SDR: SDR +Grandio. X-tra: X-tra base + Grandio. Each group was subdivided into two according to be thermocycled or not. After 24 hrs immersion in 2% methylene blue, samples weresectioned and microleakage was estimated. Res

Background: Dental caries is one of the most significant problems in world health care. Restoring carious primary teeth is one of the major treatment goals for Children, and the light activated resin restoration materials like composite, resin-modified glass ionomer and polyacid-modified which was introduced in dentistry in 1970, widely used in clinical dentistry but its application increased dramatically in recent years because of its biocompatibility, color matching, good adhesive properties of its resemblance in physical and mechanical aspects to tooth. The aim of this study: To evaluate the microleakage of Polyacid-Modified Composite resin Compared to Flowable Hybrid Composite and Resin-Modified Glass ionomer cement. Materials and me

Background: To evaluate the effect of antierosive agents (10% Nano-Hydroxyapatite (NHA), 10% Casein Phophopeptide-Amorphous Calcium Phosphate (CPP-ACP), and combination of 10% NHA and 10% CPP-ACP) on loss of minerals from enamel surface of permanent teeth treated with antierosive agents when exposed to an acidic beverage and investigate the morphological changes of treated enamel surface after demineralization with cola based beverage under Scanning Electron Microscope (SEM). Materials and Methods: Sixty maxillary first premolars were randomly divided into four groups, 15 teeth for each group. Group I treated with 10% NHA, Group II treated with 10% CPP-ACP, Group III treated with 10% NHA and 10% CPP-ACP, and Group IV did not treat with any
