Manufacturers of microprocessor-controlled prosthetic knee mechanisms, specifically the C-Leg® (Otto Bock; Minneapolis, Minnesota), claim the knee allows subjects to seamlessly change speed, descend stairs stepover-step, and recover from stumbles. To test these and other potential functions, we gave 19 transfemoral amputees the opportunity to accommodate to a C-Leg and tested them in a series o...

latitudes 308–358S. This variation is not correlated with the 200-mbar temperature. It can be explained by a decrease of High spectral resolution measurements of NH3 and PH3 lines the eddy mixing coefficient near 240 mbar from p4000 to #400 on Jupiter in the 10.5to 11.2-mm range are presented. Observacm sec between the two latitude ranges. The PH3 mixing tions, recorded on January 21–23, 1991, ...

This study presents the energy, exergy, sustainability and exergoeconomic analysis of a grid-connected solar power plant with capacity 226.4 MWe single axis tracking system consisting monocrystalline bifacial panels manufactured half-cut technology. is located in Karapınar district Konya province Türkiye, between 37°45 37°47 north latitudes 33°33 33°35 east longitudes. Based on first second law...

We report on new results from simultaneous, dual frequency, single pulse observations of PSR B0329+54 using the Giant Metrewave Radio Telescope. We find that the longitude separation of subpulses at two different frequencies (238 and 612 MHz) is less than that for the corresponding components in the average profile. A similar behaviour has been noticed before in a number of pulsars. We argue th...

Spatial variation in growth is a common feature of demersal fish populations which often exist as discrete adult sub-populations linked by a pelagic larval stage. However, it remains unclear whether variation in growth occurs at similar spatial scales for populations of highly migratory pelagic species, such as tuna. We examined spatial variation in growth of albacore Thunnus alalunga across 90...

In this paper we address the following question: do the recent advances in the orbit determination of the major natural satellites of Saturn obtained with the analysis of the first data sets from the Cassini mission allow to detect the general relativistic gravitoelectric orbital precessions of the mean longitudes of such moons? The answer is still negative. The present-day down-track accuracy ...

The 11-year cycle of solar activity follows Hale’s law by reversing the magnetic polarity of leading and following sunspots in bipolar regions during the minima of activity. In the 1996-97 solar minimum, most solar activity emerged in narrow longitudinal zones ‘active longitudes’ but over a range in latitude. Investigating the distribution of solar magnetic flux, we have found that the Hale sun...
