In recent years, using new methods in utilization of energy resources has become necessary due to environmental pollution and restriction of energy resources. The hybrid system presented in this article produced power with SOFC and Stirling engine. The purpose is to analyze a 50 kW Solid Oxide Fuel Cell that could produce enough thermal energy for a 10 kW Stirling engine working in the hybrid s...

A theoretical study of the kinetic and mechanism of 3-aug-Cope rearrangement in gas phase was performed usingDET methods at B3LYP levels of theory with 6-3114iG(d,p) bass set at 298.I5K. Equilibrium moleculargeometries and harmonic vibrational frequencies of the reactant, transition state Did product were calculated. Then,rate constant and activation thermodynamics parameters were calculated an...

The horizon structure and thermodynamics of hairy spherically symmetric black holes generated by the gravitational decoupling method are carefully investigated. temperature heat capacity hole is determined, as well how parameters affect thermodynamics. This allows for an analysis thermal stability possible existence a remanent hole. We also calculate Hawking radiation corrected generalized unce...

Recent results of quantum field theory on a curved spacetime suggest that extremal black holes are not thermal objects and that the notion of zero temperature is ill-defined for them. If this is correct, one may have to go to a full semiclassical theory of gravity, including backreaction, in order to make sense of the third law of black hole thermodynamics. Alternatively it is possible that we ...

The population dynamics and stability of ecosystems of interacting species is studied from the perspective of non-equilibrium thermodynamics by assuming that species, through their biotic and abiotic interactions, are units of entropy production and exchange in an open thermodynamic system with constant external constraints. Within the context of the linear theory of irreversible thermodynamics...
