The Rolling Resistances of Roller Skis and Their Effects on Human Performance during Treadmill Roller Skiing
Modern ski-treadmills allow cross-country skiers, biathletes and ski-orienteers to test their physical performance in a laboratory environment using classical and freestyle techniques on roller skis. For elite athletes the differences in performance between test occasions are quite small, thus emphasising the importance of knowing the roller skis’ rolling resistance coefficient, μR, in order to...
متن کاملAtmosphere Controlled Roller Hearth Kiln for High Performance Mn-Zn Ferrites
A new roller hearth kiln(RHK) has been developed, which satisfies not only the highest quality of Mn-Zn ferrites, but also large quantity of production. Using the RHK (the length is SOm), the total sintering time is reduced to less than 11 hours, that is shorter than the half of the case of pusher kiln. Then the productive capacity of the RHK achieved 100 ton per month. Moreover, the control of...
متن کاملPerformance of roller agitators for cultivation of microorganisms.
Rapidly growing aerobic organisms can deplete oxygen in the nutrient medium even when culture vessels are open to the air. Agitation is beneficial under these conditions because it tends to expose more liquid to the air, and because the mixing tends to make conditions more homogeneous throughout the volume of the medium. Rotary and reciprocating shakers are capable of high rates of aeration whe...
متن کاملInvestigation of Nonlinear Behavior of Material on Seismic Performance of Roller Compacted Concrete Dam
In this research, the effect of nonlinear behavior of concrete on seismic performance of roller compacted concrete (RCC) is discussed. Nonlinear behavior of material shows the behavior close to reality due to use of all structural capacity and it is considered the most appropriate method for design. So in this paper, by using the appropriate definition of nonlinear behavior of RCC, the Ansys so...
