A note on "A nonequilibrium theory of thermoelastic superconductors" by S-A. Zhou and K. Miya

In this note it is shown how the theory of S.-A. Zhou and K. Miya can be modified to make it completely thermodynamically consistent. The theory presented here obeys both the principle ot equipresence as well as Clausius-Duhem inequality in extended form. The thus derived results are identical to those of S.A. Zhou and K. Miya. It is shown that the final results depend explicitly on the choice made for the tree energy functional

Rayleigh-gravity waves in a heavy elastic medium

A plane wave travelling through an elastic incompressible medium with a plane boundary is considered. The motion is confined largely to the neighbourhood of the latter. In addition to elastic forces, gravitational ones are accounted for as well. The velocity of propagation is calculated applying a Lagrangian description of the problem
