Herein is described a calculation of the effective coffision frequency νeffof a low- density, shock-heated argon plasma under the influence of a weak electric field which oscillates harmonically with angular frequency ω. It is shown that, for the high frequency case ω >whereis the collision frequency in a Maxwellian gas plasma, one has νeff⋍ 2, provided that the imaginary part of the argon plasma conductivity is negligibly small in comparison to the real part. The influence of the theoretical model used to calculate νeffon the values of the electron temperatureTederived from measurements is compared with the results obtained in a data reduction for which the hard-sphere model for particle encounters was utilized.

Background: Isonatric hemodialysis aims at maintaining stable cellular hydration through a close control of natremia, considered a surrogate of tonicity. However, 2 methods are available to perform isonatric hemodialysis: one based on natremia derived from plasma conductivity (NaCond) and the other based on natremia measured at laboratory (NaLab). We compared the control of tonicity obtained by isonatric hemodialysis based on NaLab or NaCond. Methods: Changes in tonicity NaLab and NaCond were recorded during 55 hemodialysis sessions. Sessions were divided according to the variation of tonicity: hypotonic sessions (tonicity decrease ≥2 mOsm/kg); isotonic sessions (tonicity variation <2 mOsm/kg); hypertonic sessions (tonicity increase ≥2 mOsm/kg). Results: During isotonic hemodialysis, NaCond decreases significantly by 1 mmol/L, whereas NaLab remained stable. Conclusions: Isonatric hemodialysis based on NaLab and isonatric hemodialysis based on NaCond is to be distinguished. Isotonic hemodialysis could be performed by decreasing NaCond by 1 mmol/L or maintaining NaLab stability.
