Sloped solar chimney system is a solar chimney power plant with a sloped collector. Practically, the sloped collector can function as a chimney, then the chimney height can be reduced and the construction cost would be reduced.The continuity, Naver-stockes, energy and radiation transfer equations have been solved and carried out by Fluent software. The governing equations are solved for incompressible, 3-D, steady, turbulent standard model with Boussiuesq approximation  to develop for the sloped solar chimney system in this study and evaluate the performance of solar chimney power plant  in Baghdad city of Iraq numerically by Fluent (14) software with orking conditions such as solar radiation intensity (30

يعد تفعيل بناء المؤسسات التربوية ورفع مستواها من المهمات الأساسية  التي ينبغي تحقيقها من خلال تحسين دورها في التعبير عن الأرادة المجتمعية المرتبطة  والمتناغمة مع مقومات البيئة المادية والبشرية وعلى وفق متغيري الزمان والمكان، وان مسؤولية الأدارة التربوية تتمحور في أعادة النظر في هياكلها الوظيفية الادارية واستثمار الطاقات البشرية العاملة وتنظيمها ووضعها

One of the serious problems in any wireless communication system using multi carrier modulation technique like Orthogonal Frequency Division Multiplexing (OFDM) is its Peak to Average Power Ratio (PAPR).It limits the transmission power due to the limitation of dynamic range of Analog to Digital Converter and Digital to Analog Converter (ADC/DAC) and power amplifiers at the transmitter, which in turn sets the limit over maximum achievable rate.

        This issue is especially important for mobile terminals to sustain longer battery life time. Therefore reducing PAPR can be regarded as an important issue to realize efficient and affordable mobile communication services.

     Quality function deployment tool is trying to improve health services through this study that will be applied in health sector environment , and be based on applying quality function deployment tool (QFD) TO preferable evaluation of main patients requirements in order to determine the technical requirements that need most attention across improving and developing health services .                

   Main requirements are determined to patients lying in the hospital (under research) which is (educational Baghdad \ medicine city office) in Baghdad, and other technical requirements through pers

Altruism is one of good qualities of human being expressing his highness and triumph. Self control has A signifies in a lot of psychological, educational, Social, ethical and healing fields Where the higher self control relates with high degrees of carefulness accuracy, problem solving, choice. judgment and decision making. the present study aimos at measuring altruism among university students , self control among them , recognizing the statistically differences significance on self control among university students according to gender variable and recognizing the correlation between attruism and self control among university students . the sample consists of the basic application one (200) students (100) males and (100) males that had

This research aims to identify the level of Voluntary work among university students, and explore the statistical differences of voluntary work among students due the gender and major. A total of (400) male and female student from morning study were selected as a sample to achieve the research's objectives. Al-Malaki (2010) scale was adopted to collect the required data. The results revealed that men take massive part in voluntary work than women, and students of human sciences showed significant differences than those of other majors.   

Hopelessness can be consider as a subtype of depressions, it can be defined as having no expectation of good or success, giving no ground for hope, incapable of solution management or accomplishment .

Hopelessness is one of psychological variables that distinguish negative personalities because there are positive correlation between hopelessness and variables such as : anxiety, depression, suicide thought and so on .

One of the important variables correlate with hopelessness is low self-esteem, many studies indicate that there are statistically significant inverse relationship between the two variables, the present study aimed to :

1. Measures hopeless
