Theoretical Prediction of Optimum Chilled Water Distribution Configuration in Air Conditioning Terminal Unit
...Show More Authors

 The distribution of chilled water flow rate in terminal unit is a major factor used to evaluate the performance of central air conditioning unit. In this work, a theoretical chilled water distribution in the terminal units has been studied to predict the optimum heat performance of terminal unit. The central Air-conditioning unit model consists of cooling/ heating coil (three units), chilled water source (chiller), three-way and two-way valve with bypass, piping network, and pump. The term of optimization in terminal unit ingredient has two categories, the first is the uniform of the water flow rate representing in statically permanents standard deviation (minimum value) and the second category is the maximum heat transfer rate from all terminal units. The hydraulic and energy equations governing the performance of unit solved with the aid of FORTRAN code with considering the following parameters: total water flow rate, chilled water supply temperature, and variable valve opening. It was found that the optimum solution of three-way valve case at 8°C water supply temperature, 0.12 kg/s total water flow rate and valve opening order (valve 1: 100%, valve 2: 100% and valve 3: 75%) with total heat rate (987.92 Watt) and standard deviation (1.181E-3). Also, for the two-way valve case the results showed that the optimum condition at 8°C water supply temperature, 0.12 kg/s total water flow rate and valve opening order (valve 1: 75%, valve 2: 75% and valve 3: 50%) with total heat rate and standard deviation (717Watt) and (5.69E-4) respectively.

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

Die tragische Liebe im Nibelungenlied
...Show More Authors

Wer es heute beabsichtige, eine detaillierte Arbeit über die Rezeption des Nibelungenliedes zu schreiben, könnte damit einfach mehrere Bände wahrnehmen. Deswegen wird es sinnvoller sein, den Forschungsprozess auf bestimmten, aber wichtigen Aspekten zu skizzieren. Darum kann nur unter strikter Beschränkung auf die Hauptrichtungen, Hauptprobleme und Hauptfiguren des Liedes gewagt werden.

Der irakische Kritiker Moḥammed Šawqi Moḥammed Ḫalifa bedankt sich bei den „Dichtern des 12.Jahrhunderts, weil sie uns die deutschen Epen übertragen haben.“[1] Diese Epen kann man auch als Mythen betrachten, in denen sich Sagen und Märchen vermischen.

Employee Stealing or internal theft is considered from the passive practices that can’t be denied or be hidden, In spite of the hospital privacy as a serving organization that works 24\7 and deleing with human lives, they weren’t infallible from that kind of practice. To prevent or reduce this practice, it was important to search for the organizational and behavioral factors influencing internal thefts.

   

   The study problem briefly is to reach the most organizational and behavioral factors influencing internal theft, in governmental hospitals in Baghdad Rusafa Health district, this was done by analyzing (20) administrative cases, of thefts occurred in the District, also a sample of (60) sp

The current research dealt with the rapid development of industrial product design in recent times, and this development in the field of design led to the emergence of modern trends in many terms and theories to direct greater interest in the cognitive foundations of design and its relationship with the components of other natural sciences, and despite the impressive technological development, nature remains With its content of formative values and structural dimensions, it is the first source of inspiration and the source of all modern mathematical sciences and theories, as God made them tend towards organization to continue to provide us with endless inspiration. Hence, the fractional one, which is an important part of dedicating the d
