Background: Antibiotic resistance is a problem leading to difficulty in treating microbial infections thatmay occur due to many causes. For the important pharmacist role as a reference for the information and theability to access to medications, they are vital members in lowering the development of antibiotic resistance,and also they support the proper use and control of antibioticsmisuse. Our goal is comparing the knowledge,attitude, practice of undergraduate and postgraduate pharmacy students and their perceptions about thecausing factors of antibiotic resistance in Iraq.Method: A cross sectional study was conducted involving the final year bachelor and postgraduate (masterand Philosophical doctor) students from different private

Background: Propolis has received great interest because of its wide range antimicrobial activity. Propolis also called (bee glue) due to its collection by (Apismellifera) honeybees from various plants resinous substance. The aim of this study was to determine the antibacterial effect of propolis extracts (aqueous and alcoholic) on anaerobic periodontal pathogen namely Aggregatibacteractinomycetemcomitans. Materials and Methods: Strains of Aggregatibacter actinomycetemcomitans wasisolated from pockets of systemically healthy patients aged between 35-55 years old suffering from chronic periodontitis with pocket depths of 5-6 mm, the bacteria cultured on special blood Agar plates solid media. Propolis was extracted by using water and alcohol.

Bovine milk is one of the richest nutrients that contain minerals and vitamins that enhance immunity, especially in children, but because many children do not want to drink the raw milk, therefore this study aimed to enhance the sensory characteristics of raw milk by using hibiscus plant extract, which is characterized by red color and distinctive flavor as well as studying the effect of aqueous extract of Hibiscus sabdariffa on inhibiting the growth of microorganisms, by using three concentrations of the aqueous extract (0.5, 1.0 and 1.5%), where the statistical results showed a significant difference (P≤0.05) between the concentrations in color, texture and general acceptance, and the best results appeared when using

The aim of this study is to compare the effects of three methods: problem-based learning (PBL), PBL with lecture method, and conventional teaching on the understanding of thermodynamics, group work and self-directed learning skills among physics undergraduates. The actual sample size comprises of 122 students, who were selected randomly from the Physics Department, College of Education in Iraq, for academic year 2011-2012. In this study, the pre and posttest were done and the instruments were administered to the students for data collection. Inferential statistics were employed to analyze data. The independent variables were the PBL, the PBL with lecture method, and the conventional teaching. Dependent variables of statistical analysis were

بات الفساد ظاهرة عالمية تهدد المجتمعات وبقائها ، وبدت الانقسامات المجتمعية تتضاعف في البلدان التي ينتشر فيها الفساد بمختلف أنواعه وتسمياته ، حيث استكشفت الدراسة بأن التشريعات الجنائية حرصت على تقرير نظام عقابي خاص لمواجهة جرائم الفساد مما استوجب بنا بيان المظاهر القانونية للفساد السياسي المتمثل بالرشوة الدولية والرشوة الانتخابية لان الفساد لم يعد متعلقا بالجانب الاقتصادي فحسب بل امتد إلى الجوانب الأخرى

يعد تعزيز التجارة الدولية في مقدمة اهتمامات اي دولة ، فكل دولة تسعى الى تقديم خدمة مشروعات لتنمية الخدمات والبنى التحتية بوسائل عدة ، ومن اهمها قيامها بتمويل تجارتها الداخلية والخارجية مما يؤدي الى ازدهار وتحقيق التنمية والنمو المستدامين في تلك الدولة . ولكي تؤدي التجارة الدولية دوراً بارزاً في تحقيق النمو والتنمية المستدامين، لابد من توافر بيئة تجارية دولية مناسبة و نظام تجاري دولي مساند لعملية التنمية فا

Television white spaces (TVWSs) refer to the unused part of the spectrum under the very high frequency (VHF) and ultra-high frequency (UHF) bands. TVWS are frequencies under licenced primary users (PUs) that are not being used and are available for secondary users (SUs). There are several ways of implementing TVWS in communications, one of which is the use of TVWS database (TVWSDB). The primary purpose of TVWSDB is to protect PUs from interference with SUs. There are several geolocation databases available for this purpose. However, it is unclear if those databases have the prediction feature that gives TVWSDB the capability of decreasing the number of inquiries from SUs. With this in mind, the authors present a reinforcement learning-ba
