The integrability of the entropy rate and the corresponding Maxwell relations are investigated. The dissipation inequality is exploited for a simple material whose state space includes the time rate of the contact temperature. A non-equilibrium efficiency is introduced.en530 Physikintegrabilitydissipation inequalityArticle1437-4358
