Test method for axial force at pile top in centrifugal model tests on pile-net composite foundation
Yantu gongcheng xuebaoThe pile-net composite foundation is a common soft soil reinforcement measurement. In order to analyze the pile-soil stress ratio, it is necessary to measure the axial force at the pile top and the soil pressure between piles in the centrifugal model ...

Forces on Centrifugal Pump Impellers [PDF]
, 1985 Forces are exerted on a centrifugal pump impeller, due to the asymmetry of the flow caused by the volute of diffuser, and to the motion of the center of the impeller whenever the shaft whirls. Recent work in the measurement of these forces as a function

An assessment of the role of the centrifugal acceleration mechanism in high altitude polar cap oxygen ion outflow [PDF]
Annales Geophysicae, 2008 The role of the centrifugal acceleration mechanism for ion outflow at high altitude above the polar cap has been investigated. Magnetometer data from the four Cluster spacecraft has been used to obtain an estimate of magnetic field gradients. This is

Fluid-induced Rotordynamic Forces and Instabilities [PDF]
, 2006 In the late 1970s, the authors began a collaboration with our colleague Tom Caughey that helped define a new set of fluid-structure interaction phenomena in turbomachines, namely fluid-induced rotordynamic forces and instabilities. That collaboration and

Tau acetylation at K331 has limited impact on tau pathology in vivo
FEBS Letters, EarlyView.We mapped tau post‐translational modifications in humanized MAPT knock‐in mice and in amyloid‐bearing double knock‐in mice. Acetylation within the repeat domain, particularly around K331, showed modest increases under amyloid pathology. To test functional relevance, we generated MAPTK331Q knock‐in mice.
