Wave Profile for Current Bearing Antiforce Waves [PDF]
Journal of the Arkansas Academy of Science, 2013 For fluid dynamical analysis of breakdown waves, we employ a one-dimensional, three-component (electrons, ions and neutral particles) fluid model to describe a steady-state, ionizing wave propagating counter to strong electric fields. The electron gas temperature and therefore the electron fluid pressure is assumed to be large enough to sustain the ...

Best Practices in Second Stage Labor Care: Maternal Bearing Down and Positioning [PDF]
, 2007 Despite evidence of adverse fetal and maternal outcomes from the use of sustained Valsalva bearing down efforts, current second-stage care practices are still characterized by uniform directions to “push” forcefully upon complete dilatation of the cervix

Modified Slot Opening for Reducing Shaft-to-Frame Voltage of AC Motors
Energies, 2020 This paper presents a method to reduce the winding-to-rotor capacitance of electrical machines for the purpose of suppressing shaft-to-frame voltage, which causes reliability issues, such as electromagnetic interference (EMI) and bearing current.

Current-carrying friction in carbon coated ball bearing
Friction, 2023 In this work, we proposed a method for coating the whole surfaces of bearing balls uniformly by carbon film with a rotatable ball clamp. We studied the carbon/carbon friction with a self-designed current-carrying ball bearing friction test system.
