  We start with revisiting our previous results on thermoelectric response of
SNS configuration in a C-shaped Bi(x)Pb(1-x)Sr(2)CaCu(2)O(y) sample in order to
include strong fluctuation effects. Then, by appropriate generalization of the
Ginzburg-Landau theory based on admixture of s-wave and d-wave superconductors,
we consider a differential thermoelectric power (TEP) of SND junction. In
addition to its strong dependence on the relative phase \theta =\phi_s-\phi_d
between the two superconductors, two major effects are shown to influence the
behavior of the predicted TEP. One, based on the chemical imbalance at SD
interface, results in a pronounced maximum of the TEP peak near \theta =\pi /2
(where the so-called s+id mixed pairing state is formed) for two identical
superconductors (with T_d=T_s\equiv T_c). Another effect, which should manifest
itself at SD interface comprising an s-wave low-T_c superconductor and a d-wave
high-T_c superconductor (with T_d\neq T_s), predicts S_p\propto T_d-T_s for the
TEP peak value. The experimental conditions under which the predicted behavior
of the induced differential TEP can be measured are discussed.
