energy, due to its increasing usage in various broad areas has been maintained as a vital factor in economic growth and development of societies. meanwhile, natural gas is considered as one of the most important energy sources. therefore, the efficiency and the productivity of the gas companies are crucial to be assessed. numerous examples from industrial multistage processes including internal...

To improve teachers’ productivity, factors involved need to be identified and strengthened. To this end a conceptual model was initially constructed and then modified based on the feedback given by 12 experts. The final model consisted of three dimensions or topics, four sub topics, 22 concepts, or constituents, and 79 indices. The input dimension included subtopics of cognitive and behavioral ...

Conducting research, secondary data comprising a universe 63 universities were used within time frame between years 2015 2019. Through application mu...

heat recuperation is often used to improve the overall cycle efficiency of gas turbines. however, generally in small- scale gas turbines, it has a negative effect on turbine inlet temperature, pressure ratio and pressure drops, and thus decreases the overall cycle efficiency. in this paper, a thermodynamic model is performed to evaluate recovered heat as a function of heat exchanger effectivene...
