[en] In this note an attempt is presented to show that: a) an operative analysis of the concept of distinguishability of identical particles leads to the conclusion that it is not applicable to the statistical description of a physical system; statistical thermodynamics would then require the concept of indistinguishability; b) by its own the concept of indistinguishability will require, when the Planck constant is properly introduced in the deductive analysis, the uncertainty correlation relation ΔqΔp>=h.

[en] The nonconventional thermodynamical approach to subatomic physics is described with large nonequilibrium effects taken into account by introducing the temperature continuum O≤T<∞. The approach is an expansion of the classical fluctuation theory and chemical-reaction formalism. A large body of problems in low- and high-energy nuclear physics is solved in the framework of super-nonequilibrium thermodynamics. 30 refs., 2 figs., 1 tab

[en] In this Letter it is proposed another generalization of the Verlinde's maps for the case Λ≠0. Thermodynamical arguments combined with this proposal conduce to a inverse square-law cosmological term behavior

[en] A thermodynamic dataset was developed for the central part of the Ce-O system covering the range between Ce₂O₃ and CeO₂ up to about 2000 K. All literature data for the thermodynamic functions, the phase diagram and crystallography were critically assessed. The modeling of the phases takes into account their crystal chemistry including order-disorder behavior. From the dataset, diagrams were calculated for the (1) heat capacities of CeO₂ and Ce₂O₃, (2) enthalpy increment of CeO₂, (3) chemical potentials of oxygen in CeO_2-x, (4) partial enthalpies of oxygen in CEO_2-x, (5) the partial phase diagram of Ce-O and (6) chemical potentials of oxygen in the two-phase areas. These diagrams reproduce fairly well the experimental data from literature. (orig.)

[en] Focused on the problem of unbalanced propellant consumption in parallel tanks of propulsion system, a squeeze-type regulation method based on the gas law method was discussed in the paper. Taking the tank system as the research object, the thermodynamic models under isothermal, adiabatic and other conditions were given and the factors affecting the uncertainty of the model were analysed. The results show that the measurement uncertainty of the model mainly comes from the pressure measurement accuracy and the volume measurement accuracy. The model was applied to different cases and the influence law of different tank parameters on the model uncertainty was studied. It is found that under the premise of the fixed pressure difference of the parallel tanks, the uncertainty of the regulation model is almost linear with the regulation amount. In addition, the relative uncertainty of the model can be reduced effectively by improving the pressure difference of the parallel tanks. The accuracy of the regulation model can reach to 7.7%, which can meet the requirements for on-orbit use. (paper)
