Climatic influences on hillslope soil transport efficiency
The soil transport coefficient D represents the relationship between local topographical gradient and soil flux in the landscape evolution model. This work presents new estimates of the soil transport coefficient D at 9 sites and compares them, along with a compilation of 16 previously published …

Efficiency and Motor Skill Learning (Locomotion, Physical, Physiology, Evolution, Practice)
Improvements in mechanical efficiency (E%) and transport efficiency (cal/m/kg) with practice, were investigated using 5 physically fit adult male subjects crawling on a horizontal motor-driven treadmill at .76 m/s. E% was the ratio of the work output of individual limb segments, based on a link …

Topographic asymmetry and climate controls on landscape evolution
… published estimates of slope-dependent soil transport efficiency across a range of climates. I find that soil transport efficiency increases with mean annual precipitation and the aridity index, a measure that describes water availability for plants. I also find that soil transport efficiency …

Trade Facilitation and Export diversification in South Africa
… export diversification. We find that border and transport efficiency contributes significantly to export diversification and the effect is confirmed when examining export diversification between countries. We also find that ocean ports, airports, custom procedures and number of days to import …

Establishing a calibration for a microwave plasma continuous emissions monitor
… is necessary to determine the analyte metal mass transport efficiency of the nebulizer system. A novel new approach to determine the nebulizer efficiency during plasma operation was tested in this thesis. A 0.1-mm tungsten filament attached to a 4- mm diameter alumina rod was used to introduce a …
