The Equation of State of Biogas

open access: yesActa Universitatis Agriculturae et Silviculturae Mendelianae Brunensis, 2017
The presented work deals with a state behavior of real gas, biogas. Theoretical approach was utilized for processing of this work. Compressibility factor was calculated with help of two equation of state – Van der Waals equation and Redlich‑Kwong ...

Effect of Thermoelastic Properties of the Pyrope-Almandine Solid Solutions on the Entrapment Pressure of Garnet-Related Elastic Geobarometer

open access: yesFrontiers in Earth Science, 2022
The pyrope (Prp)–almandine (Alm) solid solutions are the most fundamental garnet components on the Earth, and both the quartz inclusions in garnet (QuiG) barometry and the garnet inclusions in diamond barometry need to be constrained by the thermoelastic

Equation of state for agents on graphs

open access: yes, 2005
Choice models for populations of agents on graphs are studied in terms of statistical thermodynamics. Equations of state are derived and discussed for different connectivity schemes, utility approximations, and temperature and volume regimes.

Magnetar QPOs and Neutron Star Crust Elasticity

open access: yesUniverse
The crust region is a tiny fraction of neutron stars, but it has a variety of physical properties and plays an important role in astronomical observations. One of the properties characterizing the crust is elasticity. In this review, with the approach of

Cold quarks in medium: an equation of state

open access: yes, 2009
We derive a compact, semi-algebraic expression for the cold quark matter equation of state (EoS) in a covariant model that exhibits coincident deconfinement and chiral symmetry restoring transitions in-medium.

Systematics of Crystalline Oxide and Framework Compression

open access: yesCrystals
A universal equation of state of solids is one of the far goals of condensed matter science. Here, it is shown that within pressures of 2–100 GPa, the compression of oxides and oxide-based networks follows a linear relation between the molar volume and ...

Quark matter equation of state and stellar properties

open access: yes, 2012
In this paper we study strange matter by investigating the stability window within the QMDD model at zero temperature and check that it can explain the very massive pulsar recently detected.

Critical exponents values for fluids and linear scaled equation of state

open access: yesLittera Scripta, 2011
The behavior of substance in the vicinity of a critical point is the focus of great scienti fic interest. A liquid-liquid phase transition in the supercooled region could influence biochemical or precipitation processes. It is interesting that water in a

CHANGE IN THE BARIC DEPENDENCES OF THE THERMOPHYSICAL PROPERTIES OF A NIOBIUM NANOCRYSTAL WITH A CHANGE IN SIZE

open access: yesФизико-химические аспекты изучения кластеров, наноструктур и наноматериалов, 2019
From a general point of view, the equation of state and the change in thermophysical properties of Nb nanocrystals along 300 K and 3000 K isotherms with increasing pressure were calculated on the basis of the Mie – Lennard – Jones pair interatomic ...
