In this study the resistive and propulsive forces of three swimmers swimming two types of crawl stroke—the glide stroke and the continuous stroke—were measured. An apparatus was constructed which utilized strain gauges to measure these forces. It was found that the continuous stroke was faster ...

Evolution of Dioecy in Flowering Plants Presents a study on the evolution of dioecy in flowering plants. Factors contributing to the neglect on selective forces underlying the evolution of dioecy; Belief regarding the presumed rarity of the dioecious condition; Attempt by the ... Bawa,K S - 《...
Average activities to produce 20N bite-forces for each muscle and subject determined thresholds (5–80%·T20N) for subject-specific DF calculations during exercises performed in laboratory and natural environments. Subjects self-recorded via portable electromyography equipment during in-field leg-extension...
The contact geometry, creepages and creep forces of wheelset/track with two types of wheel profiles in rolling contact are investigated with numerical methods. In the analysis of the creep forces with Kalker theory of three-dimensional elastic bodies in rolling contact with non-Hertzian form, fini...
A typicalexample of physical system for which damping forces have to beinvolved into equations is a damped spring mechanicaloscillator. Here we use two models of the damping force, beingproduced by Foucault currents and by the force of the drag inair.关键词:...
This forces the gas into the heated cylinder, where it quickly heats up, building pressure, at which point the cycle repeats. The Stirling engine only makes power during the first part of the cycle. There are two main ways to increase the power output of a Stirling cycle: Increase power ...
encapsulated – they are subject to a wide array of perceptual and social forces and can be introspected on and revised in ways not possible with other cognitive functions (Connors & Halligan, 2015).Coltheart (2017)acknowledged the problem of modularity and suggested that, as there is currently...
Both refer to a decline in a currency’s value, but depreciation is a gradual decline in the value of a currency relative to other currencies in a floating exchange rate system because of market forces, interest rates, or economic performance.Devaluationis a deliberate downward change in the...
It is hard to approach the topic "unity and diversity in#13; communication" without seeing in it a convergence of anatagonic forces at least from two perspectives, not only because of the conjunction "and" but also because of the meaning of "communication".#13; It may therefore be read ...
