BACKGROUND How space suits affect the preferred walk-run transition is an open question with relevance to human biomechanics and planetary extravehicular activity. Walking and running energetics differ; in reduced gravity (<0.5 g), running, unlike on Earth, uses less energy per distance than walking. METHODOLOGY/PRINCIPAL FINDINGS The walk-run transition (denoted *) correlates with the Froude...

Thermo-chemical models of the dynamics of the internal differentiation of the Moon require accurate knowledge of the density of lunar minerals and melts at a range of high pressure, high temperature conditions. Here we present a comparative study of high-pressure, high-temperature density determinations of possible primitive lunar melts, as represented by volcanic glass beads sampled during the...

This paper summarizes the bidding procedures proposed by NEPOOL for the Energy, Reserve, Automatic Generation Control (AGC), and Operable Capability markets. Experience with the Installed Capability market is also described. On October 29, 1997 FERC accepted NEPOOL’s previous filings proposing the implementation of the Installed Capability Market by November 1, 1997, but suspended its implement...
