Exergy analysis of the musculoskeletal system efficiency during aerobic and anaerobic activities
(2018)© 2018 by the authors.The first and second laws of thermodynamics were applied to the human body in order to evaluate the quality of the energy conversion during muscle activity. Such an implementation represents an important ... -
Tool wear evaluations in friction stir processing of commercial titanium Ti-6Al-4V
(2013)This research addresses the application of friction stir welding (FWS) of titanium alloy Ti-6Al-4V. Friction stir welding is a recent process, developed in the 1990s for aluminum joining; this joining process is being ... -

Exergy performance of human body under physical activities
(2013)The aim of this work is to apply performance indicators for individuals under physical activity based on the concepts of exergy destroyed and exergy efficiency. The cardiopulmonary exercise test is one of the most used ... -
The effect of altitude and intensity of physical activity on the exergy efficiency of respiratory system
(2014)The effect of altitude on exercise performance of lowlanders has long been discussed, but it is still unclear whether the performance reduction is related to inefficiency of the respiratory system, body tissues or both. ... -
