The Influence of Ski Waist-Width and Fatigue on Knee-Joint Stability and Skier’s Balance

Applied Sciences, 2020
Alpine skiing is a complex sport that demands a high level of motor control and balance. In general, skiers are prone to deterioration in the state of fatigue due to using inappropriate equipment. As a consequence, the risk of injury might increase. This

Evaluating the performance of three sensor types for long-term measurement of suctions in gold tailings [PDF]

E3S Web of Conferences, 2023
A key aspect of the stability of a tailings dam is the pore pressure regime within the dam. Although gold tailings can exist in an unsaturated state in the field, the measurement of negative pore pressures (matric suctions) in active gold tailings dams ...

Comparisons of soil suction induced by evapotranspiration and transpiration of S. heptaphylla [PDF]

, 2015
For a given evapotranspiration (ETr), both soil evaporation and plant transpiration (Tr) would induce soil suction. However, the relative contribution of these two processes to the amount of suction induced is not clear. The objective of this study is to

Electrowetting-Based Microdrop Tensiometer

Langmuir, 2008
We performed electrowetting (EW) contact angle measurements to determine the interfacial tension between aqueous drops laden with various inorganic and organic solutes and various ambient oils. Using low frequency AC voltage, we obtained interfacial tensions from 5 to 72 mJ/m 2, in close agreement with macroscopic tensiometry for drop volumes between ...
