Background: Irrigation of the canal system permits removal of residual tissue in the canal anatomy that cannot be reached by instrumentation of the main canals so the aim of this study was to compare and evaluate the efficiency of conventional irrigation system, endoactivator sonic irrigation system,P5 Newtron Satelec passive ultrasonic irrigation and Endovac irrigation system in removing of dentin debris at three levels of root canals and to compare the percentage of dentin debris among the three levels for each irrigation system. Materials and methods: Forty extracted premolars with approximately straight single root canals were randomly distributed into 4 tested groups of 10 teeth each. All canals were prepared with Protaper Universal ha

Background: Diabetes is a metabolic disorder characterized by chronic hyperglycemia due to an inability to produce insulin. Uncontrolled or poorly controlled diabetes is clinically associated with increased susceptibility to delay healing. Many recent researches have shown that stem cell therapy can be the best choice for treatment of this disease. The aims of this research were investigating regeneration of pancreatic beta cells of diabetic induced rabbits after stem cell transplantation. Materials and Methods: 64 rabbits weighting an average of (2.5 - 3 kg) were used in this experimental study, and divided into 4 groups as follows; group A ( contains 16 healthy rabbits regarded as control group ) , Group B ( contains 16 diabetic rabbits

The problem of steady, laminar, natural convective flow in an square enclosure with and without partitions is considered for Rayleigh number (103-106) and Prandtl number (0.7). Vertical walls were maintained isothermal at different temperatures while horizontal walls and the partitions were insulated. The length of partition was taken constant. The number of partitions were placed on horizontal surface in staggered arrangement from (1– 3) and ratio of partition thickness (H/L= 0.033, 0.083, 0.124). The problem is formulated in terms of the vorticity-stream function procedure. A numerical solution based on a program in Fortran 90 with the finite difference method is obtained. Representative results illustrating the effects of the thickn

This study investigates the Linguistic and Conceptual equivalence of Conner’s Revised Scales when applied on a Sudanese sample. Sudanese parents and teachers completed behavior-rating scales on a stratified sample of 200 children. These instruments were based on Conner’s parent -48 and teacher-28 questionnaires. Following a reliable translation into Sudanese Arabic the test-retest reliability of the items and the internal consistency of the original Conner’s' revised scales were explored. The associations between scale scores and between parents and teachers scores were also examined. Both instruments displayed good reliability and the original Conners scales had satisfactory internal consistency. The inter-correlation sugg

الرّهاب، اضطراب نفسيّ واسع الانتشار، وتُشير الدّراسات الحديثة إلى أن نسبة انتشاره تتراوح ما بين (7%-14%) في أغلب المجتمعات، وهو اضطراب مُزمن ومُعطّل للحياة الاجتماعيّة، ولكنّه قابل للعلاج. ويتفق العلماء على أن عدم إدراك المعاق بصريًّا للبيئة المحيطة به، وأركانها يجعل تكّيفه معها محصورًا في إطارٍ ضيق، وبذلك تتبلور مشكلة البحث في الإجابة عن التساؤل الآتي: ما مستوى الرّهاب لدى التلامذة ضعاف البصر في المدارس الاب

The personality of an individual comes from the social adjustment which is
represented by the individual interaction with the others. If the individual has acceptable

which represents emotional, social, rational and physical characteristics.
These characteristics have their importance to be studied within college students

Writing his own biography is like making his confession in front of the altar of the truth. In The words,Sartre writes his own child life from the view of a philosopher-thinker. He presents his days spent justlike a series of images carrying advices and experiencesto whole the world. The words shows the life of a small orphan who met early with death when he lost his father. Then death becomes as his shadow that goes with him on day and night until the end. The mother of the little Poulou seems like the mirror that reflects the sadness and the melancholy of the dark and gloomy days. The small Poulou becomes his only consolation in misery. The little Jean -Paul lives completely in a literary atmosphere . Because his grandfather Karl Schwe
