Query: Dufour and Soret effects in a magnetized and non-magnetized plasma   It is well known that magnetic fields affect heat conduction in a different
way in the direction parallel and perpendicular to the field. In this paper a
formal derivation of this phenomenon and analytical expressions for the
transport coefficients based in the Boltzmann equation are presented. Moreover,
the Dufour effect or diffusion thermo effect is usually ignored in plasma
transport theory. In this work, analytic expressions for the parallel and
perpendicular thermal conductivities as well as the coefficients for both the
thermal diffusion, or Soret, effect and the Dufour effect are formally derived.
It is also shown how the heat conduction in the perpendicular direction
decreases with increasing magnetic field and how in both directions the
diffusion thermo effect is significant compared to thermal conduction. Other
aspects of this work are also emphasized.
