The energetics of walking on sand and grass at various speeds

Article Abstract:

The energetics of walking on sand and grass are investigated by controlling the speed of the participants and measuring their physiological parameters like heart rate, oxygen uptake, carbon-di-oxide exhalation, ventilation and relative oxygen uptake. Results reveal a significant increase in all physiological indices indicative of energy expenditure when walking on sand compared to grass at 3-7 kilometer (km) per hour, with the greatest disparity in relative oxygen consumption at 5 km per hour.

Parallel approaches to composite production: Interfaces that behave contrary to expectation

Article Abstract:

PRO-fit and EvoFIT versions of facial composite systems that show multiple faces during construction to closely resemble face processing that is natural is described. The PRO-fit parallel interface interfered with holistic face processing and hence was not very good as the 'serial' version.
