  This talk provides a natural continuation of the talk presented by Andreas
Fring in this conference. Part I was focused on explaining how the DC
conductance for a free Fermion theory in the presence of different kinds of
defects can be computed by evaluating the Kubo formula. In this talk I will
focus on an alternative method for the computation of the same quantity, that
is the evaluation of Landauer formula. Once again, the integrability of the
theories under consideration will be exploited, since a thermodynamic Bethe
ansatz analysis provides all the input needed in that case, apart from the
corresponding reflection and transmition amplitudes of the defect. The basic
conclusion of our analysis will be the perfect agreement between the two
different theoretical descriptions mentioned.
