In a previous communication (Green, 1998), the initial step in ion channel gating for voltagegated channels was attributed to the tunneling of a proton between groups with similar pK values, under the in#uence of an electric "eld. This is in contrast to the standard thermally activated model, which

โฆ Synopsis
An analytical model has been proposed for predicting the vibration frequencies of rolling bearings and the amplitudes of significant frequency components due to a localized defect on outer race, inner race or on one of the rolling elements under radial and axial loads. The model predicts a discrete spectrum having peaks at the characteristic defect frequencies and their harmonics. In the case of an inner race defect or a rolling element defect under a radial load, there are sidebands around each peak. The effect of load and pulse shape on the vibration amplitude has been considered in the model. Typical numerical results for a 6002 deep groove ball bearing have been obtained and plotted. A comparison with the experimental values obtained from published literature shows that the model can be successfully used to predict amplitude ratios among various spectral lines.
