The Nano materials play a very important role in the heat transfer enhancement. An experimental investigation has been done to understand the behaviors of nano and micro materials on critical heat flux. Pool boiling experiments have used for several concentrations of nano and micro particles on a 0.4 mm diameter nickel chrome (Ni-Cr) wire heater which is heated electrically at atmospheric pressure. Zinc oxide(ZnO) and silica(SiO₂) were used as a nano and micro fluids with concentrations (0.01,0.05,0.1,0.3,0.5,1 g/L), a marked enhancement in CHF have been shown in the results for nano and micro fluids for different concentrations compared to distilled water. The deposition of the nano particles on the heater surface was the rea

ان مسألة الاجور الادارية من المسائل التي يعيشها الناس ويتعاملون بها وقد اشتغلت هذه المسألة استقلالاً غير اخلاقي وغير شرعي من قبل بعض المؤسسات والمصارف وقد انخدع كثير من الناس حتى وقعوا في شباكها فوقوا في الحرام. لذا فقد بينت حقيقة الأجور الإدارية وبيان موقف الشرع منها وفرق الأجور الإدارية وبين الفائدة الربوية. وعُبر عن الاجور الادارية بالمصاريف الادارية أو الرسوم الادارية أو التكاليف الإدارية ، ولم اجد حس

The current research includes the adsorption of Rhodmine-B Dye on the surface of Citrus Leaves using the technique of UV. Vis spectrophotometer to determine data of quantitative adsorption at various contact time, ionic strength, PH and temperature conditions. As a function of temperatures 25,35,45,55 ⁰C, the dsorption phenomenon was examined, and the results showed that Rhodamine-B adsorption Citrus leaves rose with increasing temperatures on the surface (endothermic process). Using various NaCl solution concentrations, the effect of ionic strength on adsorption has also been studied. Increasing the importance of ionic strength has been shown to improve the amount of adsorption of Rhodamine-B on citrus leaves at constant temp

تتمثل الأبعاد الجيوبوليتكية لميناء مبارك الكويتي على العراق في تأثيره على الموقع البحري والمصالح الاقتصادية والاستراتيجية للعراق. فالميناء يقع قرب الممرات البحرية العراقية، مما يثير مخاوف بشأن حرية الملاحة والوصول إلى الخليج العربي. كما قد يؤثر اقتصاديًا في حركة التجارة وكفاءة الموانئ العراقية، خاصة مشروع ميناء الفاو الكبير. سياسيًا، أثار المشروع نقاشات حول الحدود البحرية والعلاقات العراقية–الكويتية،

The research aims mainly to the role of the statement style costs on the basis of activity based on performance (PFABC) to reduce production cost and improve the competitive advantage of economic units and industrial under the modern business environment dominated by a lot of developments and changes rapidly, which necessitates taking them and criticize them to ensure survival and continuity.  The research problem is the inability of traditional cost methods of providing useful information to the departments of units to take many administrative decisions, particularly decisions related to the product and calculating the costs of the quality of the sound and the availability of the need and the ability to replace methods capa

The administration on the basis of the activities designed to evaluate the performance of activities in terms of cost, time and quality by identifying activities that add value and those that are no add value and  enables the administration of making up their own continuous improvement in production, through lower costs and reduce the time and improve the quality   and reduce the incidence of spoilage and waste, y based search Ally premise that (the continuous improvement of the adoption of management style on the basis of the activities helps management in decision-making wise to reduce  costs) to prove the hypothesis has sought research to achieve its goal of  Alkadivh and Alkoppelan     &nb

   The research aims to identify the importance of using the style of the cost on the basis of activity -oriented in time TDABC and its role in determining the cost of products more equitably and thus its impact on the policy of allocation of resources through the reverse of the changes that occur on an ongoing basis in the specification of the products and thus the change in the nature and type of operations . The research was conducted at the General Company for Textile Industries Wasit / knitting socks factory was based on research into the hypothesis main of that ( possible to calculate the cost of activities that cause the production through the time it takes to run these activities can then be re- distributed product cost
