The transition from the superconducting to normal state in a magnetic field was considered as irreversible thermodynamic process before 1933 because of Joule heating. But all physicists became consider this reversible after obvious contradiction Meissner effect with second law thermodynamics if is process. In order avoid thermodynamics, postulated thirties last century that surface screening cu...

The positive increase of entropy that occurs in irreversible processes has always served as a criterion for distinguishing the past from the future. The unerring ability of the Second Law of Thermodynamics to predict the order of events in time based on a change of entropy in macroscopic systems has led to the concept of the thermodynamical arrow of time. In this paper we analyze a cyclical rev...

The puzzle of how time-reversible microscopic equations of mechanics lead to the time-irreversible macroscopic equations of thermodynamics has been a paradox since the days of Boltzmann. Boltzmann simply sidestepped this enigma by stating "as soon as one looks at bodies of such small dimension that they contain only very few molecules, the validity of this theorem [the second law of thermodynam...

synopsis In a previous paper it was shown that a modified form of the Enskog equation, applied to mixtures of hard spheres, should be considered as the correct extension of the usual Enskog equation to the case of mixtures. The main argument was that the modified Enskog equation leads to linear transport coefficients which are in complete agreement with the laws of irreversible thermodynamics. ...

We consider the question of the existence of a generalized H-theorem in the context of the variational method in the information-theoretical approach that generates the nonequilibrium statistical operator formalism. After brie y reviewing how the latter provides mechano-statistical foundations for phenomenological irreversible thermodynamics, the socalled Informational Statistical Thermodynamic...

Most existing phenomenological heat conduction models are expressed by temperature and heat flux distributions, whose definitions might be debatable in heat conductions with strong non-equilibrium. The constitutive relations of Fourier and hyperbolic heat conductions are here rewritten by the entropy and entropy flux distributions in the frameworks of classical irreversible thermodynamics (CIT)...

In the present work, we combine concepts and tools from Irreversible Thermodynamics and Control Theory in a contribution to unravel the origin of complex nonlinear behaviour in biochemical networks. Regarding cells as thermodynamic systems, we can consider dynamic evolution of intracellular processes in terms of the combined action of an endogenous entropy production and the entropy flux associ...

Transport phenomenon across membranes are very important as they work as guiding principles for drug permeation studies across biological membranes. Classical thermodynamics is confined to the systems of equilibrium i.e. to reversible processes only and cannot be applied to the irreversible systems where variables defining the systems are changing with time and situation. The utility of irrever...

We extend to the Horndeski realm irreversible thermodynamics description of gravity previously studied in "first generation" scalar-tensor theories. identify a subclass theories as an out-of--equilibrium state, while general relativity corresponds equilibrium state. In this context, we effective heat current, "temperature gravity", and shear viscosity space The identification is accomplished by...
