Exergy analysis is one method for studying of energy efficiency and optimization for systems and machines including dryers. Fluidized bed dryers despite widespread usage have low energy efficiency. Therefore a new method has been proposed that the fluid bed drying has been combined with thick (Fix) bed dryer as outlet air from the fluidized bed section is conducted to the thick bed section for drying the other material or same kind material that existed in the first section. Experiments were performed in three temperatures, 50, 60 and 70oC and three bed depth in down, fluidized bed drying, 4, 6 and 8 cm and two beds depth in up, batch bed drying, 6 and 8 cm. The results show that exergy loss of top floor is lower than down floor. And also increasing in bed depth of down floor causes increasing in exergy loss of top floor. But exergy loss of down floor decreases with increasing in bed depth of top floor.

Ian McEwan’ s Solar has been the subject of many a debate, mostly due to its controversial representation of climate change’ s cause and the solution offered for the global disaster. The paper explores the novel’ s judgment over climate change’ s fountainhead and the protagonist’ s vain project to save the earth. The scope of the study encompasses the narrator’ s accounts of the characters and events in the story. In the light of David Harvey’ s notion of ‘ spatial Fix, ’ the study, through a close reading of the novel, focuses on the context within which the story unfolds in order to elaborate on the transformation of the earth into a globalized monolithic built environment called ‘ the planet’ for the sake of efficiency and free flow of capital and commodities. It also argues that the protagonist’ s solar energy generation project is a neo-liberal initiative to replace a less lucrative production mode and tackle the system’ s critical spell of overaccumulation, rather than global warming.

Objective: The purpose of this study was to investigate the factors affecting the incidence of collusion in Iranian football.Methodology: The present study is descriptive-correlational in terms of its purpose. The statistical population of the study consisted of all managers and experts, coaches, referees and athletes of the Premier League, who were selected through purposive sampling (172 persons). The validity of the researcher-made questionnaire was confirmed by experts (n = 11). Its reliability was calculated using Cronbach's alpha test (0.938) and combined reliability. Structural equation modeling with PLS3 and SPSS24 software was used for data analysis and model fit.Results: The results of the path analysis showed that the causes and drivers of collusion have a significant effect on the behavior of actors and agents of collusion, methods and tools of collusion and the consequences and consequences of collusion. Factors of collusion methods and tools also had a significant effect on the behavior of actors and agents of collusion and the consequences and consequences of collusion. Also the behavior of actors and actors of collusion had a significant effect on the results and consequences of collusion. Finally, the effect of all the mediating variables on the research was also significant.Conclusion: According to the results of this study, it can be said that the model presented in this study can be a good roadmap for identifying the factors influencing collusion formation in Iranian soccer sport in order to prevent these behaviors.

This paper studies a discrete Fix-up limit policy for two systems. Because sometimes, a failed system cannot be completely Fixed at the optimal Fix-up limit time due to some logistic issues. This paper provides a chance to complete Fixing up a failed system within a discrete Fix-up limit time LT (L=1,2,3…) for a Fixed T. The explicit expression of the expected long-term cost per unit time is derived for the two systems based on the assumptions of the systems. Finally, a numerical example is given to illustrate the theoretical results of the proposed model.
