In the present study, an experimental study is carried out to investigate the effect of adding Al and Cu nanoparticles to the base fluid (water) on the heat transfer rate in a spirally coiled tube. The spirally coiled tube is fabricated from the straight copper tube with the inner and outer coil diameters of 100 and 420 mm, respectively. The experiments have been done for water and two types of...

The present paper aims to study the effect of skill complexity during different delays on bidirectional transfer on bidirectional transfer of tracking task in different stages (pretest, acquisition phase, immediate transfer, one-day delayed transfer, two-day delayed transfer, and seven-day delayed transfer). Three variables including handedness, time lagges, and skill complexity were studied. T...

in this paper, a new approach to modify cable tension measuring mechanism is described; furthermore, the constructed boards which amplify load cell output are introduced. this approach has some advantages including of providing feedback for motors, evaluating the robot’s ultimate load carrying capacity, improving the motor control system and estimating the vibrating deflections of the end effec...

background: the complexity of assisted reproductive technology (art) increased during the last decades. new scientific and medical findings as well as the statutory requirements for improving the safety and the outcome of art were the main impetus for its development. while therapy planning is done and art is used by the ivf centers, the medical support and monitoring of patients is conducted b...

The aim of this research is the determining strategy of technology transfer in the upstream oil industry (oil fields development) of the Islamic Republic of Iran with the use of effective conditional models of technology transfer. In this study, the views and attitudes of 30 managers and experts familiar with the issues of technology transfer, including transfer of technology in the development...
