- Thermodynamic stability conditions for nonadditive composable entropies. Wada, T. // Continuum Mechanics & Thermodynamics;Mar2004, Vol. 16 Issue 3, p263
The thermodynamic stability conditions (TSC) of nonadditive and composable entropies are discussed. Generally the concavity of a nonadditive entropy with respect to internal energy is not equivalent to the corresponding TSC. It is shown that both the TSC of Tsallis'entropy and that of the...

- Tsallis entropy: how unique? Abe, S. // Continuum Mechanics & Thermodynamics;Mar2004, Vol. 16 Issue 3, p237
It is shown how, among a class of generalized entropies, the Tsallis entropy can uniquely be identified by the principles of thermodynamics, the concept of stability, and the axiomatic foundations.

We recently proposed a theory [Suresh, J. Chem. Phys. 113, 9727 (2000)], based on the principles of statistical mechanics, for describing the temperature variation of static dielectric constant of water and the average number of H-bonds per molecule in the liquid phase. The theoretical model...

We solve a two-dimensional model for polymer chain folding in the presence of mechanical pulling force (f) exactly using equilibrium statistical mechanics. Using analytically derived expression for the partition function we determine the phase diagram for the model in the f-temperature (T)...

In this paper we discuss the traditional approaches to the problem of the arrow of time. On the basis of this discussion we adopt a global and nonentropic approach, according to which the arrow of time has a global origin and is an intrinsic, geometrical feature of spaceâ€“time. Finally, we...

- Kinetics and thermodynamics of a novel endoglucanase (CMCase) from Gymnoascella citrina produced under solid-state condition. Jabbar, Abdul; Rashid, Muhammad; Javed, Muhammad; Perveen, Raheela; Malana, Muhammad // Journal of Industrial Microbiology & Biotechnology;Jun2008, Vol. 35 Issue 6, p515
Gymnoascella citrina produced two isoforms of endoglucanases (CMCase-I and -Ð†Ð†) under solid-state condition. Purified CMCase-I was novel because it was apparently holoenzyme in nature. The enzyme was monomeric as its native and subunit mass were almost the same, i.e., 43 and 42 kDa,...

- General thermostatistical formalisms based on parameterized entropic measures. Plastino, A. R.; Miller, H. G.; Plastino, A. // Continuum Mechanics & Thermodynamics;Mar2004, Vol. 16 Issue 3, p269
We revisit the concept of generalized thermostatistical formalisms, based on extremizing parameterized entropic functionals subject to appropriate constraints, in order to incorporate an (effective) temperature dependence of the entropic parameters and of parameters characterizing the relevant...

- Rapid calculation of partition functions and free energies of fluids. Do, Hainam; Hirst, Jonathan D.; Wheatley, Richard J. // Journal of Chemical Physics;11/7/2011, Vol. 135 Issue 17, p174105
The partition function (Q) is a central quantity in statistical mechanics. All the thermodynamic properties can be derived from it. Here we show how the partition function of fluids can be calculated directly from simulations; this allows us to obtain the Helmholtz free energy (F) via F = -kBT...
