application of cogeneration systems based gas turbine for heat and power production is increasing. because of finite natural energy resources and increasing energy demand the cost effective design of energy systems is essential. cgam problem as a cogeneration system is considered here for analyzing. two new approaches are considered, first in thermodynamic model of gas turbine and cogeneration ...

BACKGROUND In this study we investigated the predictability of three thermodynamic quantities related to complex formation. As a model system we chose the host-guest complexes of beta-cyclodextrin (beta-CD) with different guest molecules. A training dataset comprised of 176 beta-CD guest molecules with experimentally determined thermodynamic quantities was taken from the literature. We compared...

The Bose-Einstein condensation and the liquid-gas first-order phase transition are studied in interacting pion matter. Two phenomenological models used: mean-field model hybrid model. Free parameters fixed by fitting lattice QCD data on Bose condensate density at zero temperature. In spite of some minor differences, two demonstrate an identical qualitative very close quantitative behavior for t...

Objectives: Herbal medicine is known as a valid alternative treatment. Salvia Reuterana, which has been used in the Iranian traditional medicine, is mostly distributed in the central highlands of Iran. Salvia Reuterana is a medicinal herb with various therapeutic usages. The aim of the present review is to take account of pharmacological properties of Salvia Reuterana. Materials and Methods: Th...

The fractional Zener constitutive law is frequently used as a model of solid-like viscoelastic behavior. In this work, class linear models type, which generalize the model, studied by use Bernstein functions technique. We prove that corresponding relaxation moduli are completely monotone under appropriate thermodynamic restrictions on parameters. Based property, we study propagation function an...

Density Functional Theory is situated within the evolution of Quantum Chemistry as a facilitator of computations and a provider of new, chemical insights. The importance of the latter branch of DFT, conceptual DFT is highlighted following Parr's dictum "to calculate a molecule is not to understand it". An overview is given of the most important reactivity descriptors and the principles they are...

ThermoData Engine (TDE) is the first full-scale software implementation of the dynamic data evaluation concept, as reported in this journal. The present article describes the background and implementation for new additions in latest release of TDE. Advances are in the areas of program architecture and quality improvement for automatic property evaluations, particularly for pure compounds. It is...
