MATCHING BETWEEN THEORETICAL AND EXPERIMENTAL-DATA FOR ELF ION-TRANSPORT EFFECTS

In recent years, several studies have been focused on the problem of n onthermal interaction between extremely low-frequency (ELF) electromag netic fields and cell environment at membrane level. In the paper, to analyse the dynamic effects of weak static and harmonic fields on char ged particles, some new considerations have been developed, based on t he Lorentz model. The authors have reached a suitable formulation so t hat the data processing has led expressly to the' evaluation of ionic- velocity components against magnetic-field amplitudes and frequencies, as well as a viscosity parameter. Even through a direct and rough com parison, the results of the authors' investigation have demonstrated a n interesting agreement with some experimental data relative to ionic fluxes through cell membranes. Indeed, by means of an algorithm based on the techniques of the inversion theory, the authors' have found def inite values of the viscosity parameter for which the expected resonan t behaviours (amplitude and frequency windows) fit existing experiment s well. It seems worthy of interest that such viscosity values fall wi thin a consistent, narrow range of low amplitude.
