Ye'elimite occurs in nature and calcium sulfoaluminate cements. The thermodynamic properties of synthetic orthorhombic ye'elimite, Ca4Al6O12SO4, were determined experimentally using low-temperature relaxation calorimetry at higher temperatures differential scanning drop calorimetry. heat capacity, Cp, 480 J/mol/K standard entropy, S°, 487 298 K measured. These values compare well with those cal...

The thermodynamic properties of a non-interacting ideal Hadron Resonance Gas (HRG) finite volume have been studied in the presence an external magnetic field. inclusion background field calculation potential is done by modification dispersion relations charged hadrons terms Landau quantization. generalized Matsubara prescription has employed to take into account size effects which periodic (ant...

This paper presents a new approach to the observation and the control of the behavior of multiple autonomous robots. It is the microscopic observation expressed by dynamic equations that has been commonly employed to observe the multi-robot behavior. However, the approach has the difficulties in estimating the behavior and the mutual interactions of robots. Furthermore, it is hard to realize th...

Recent years have seen a tremendous progress in the microscopic theoretical treatment of surfaces and processes on surfaces. While some decades ago a phenomenological thermodynamic approach was dominant, a variety of surface properties can now be described from first principles, i.e. without invoking any empirical parameters. Consequently, the field of theoretical surface science is no longer l...

All current formulations of nonequilibrium thermodynamics open chemical reaction networks rely on the assumption non-interacting species. We develop a general theory that accounts for interactions between species within mean-field approach using activity coefficients. Thermodynamic consistency requires rate equations do not obey standard mass-action kinetics but account with concentration depen...

We study the thermostatistics of q-deformed bosons and fermions obeying the symmetric (q<-->q(-1)) algebra and show that it can be built on the formalism of q calculus. The entire structure of thermodynamics is preserved if ordinary derivatives are replaced by an appropriate Jackson derivative. In this framework, we derive the most important thermodynamic functions describing the q-boson and q-...
