The thermodynamic properties of the supercooled liquid state of the mW model of water show anomalous behavior. Like in real water, the heat capacity and compressibility sharply increase upon supercooling. One of the possible explanations of these anomalies, the existence of a second (liquid-liquid) critical point, is not supported by simulations for this model. In this work, we reproduce the an...

In this paper further considerations has been given to the fluctuation model of diffusion, and equations have been derived which express the self-diffusivity of liquid metals as a function of temperature and pressure. For liquid metals which are characterized by pair potentials which are relatively deep compared with kT, D is predicted to vary in a linear fashion with T at constant volume. At c...

In the novel superfluid polar phase realized in liquid $^{3}\mathrm{He}$ highly anisotropic aerogels, a quantum transition to polar-distorted A (PdA) may occur at low but finite pressure ${P}_{c}(0)$. It is shown that nontrivial dynamics of critical fluctuation PdA order induced by presence both columnar impurity scattering leading Anderson's theorem for and line node quasiparticle gap state, t...

Spherically collapsing cavitation bubbles produce a shock wave followed by a rebound bubble. Here we present a systematic investigation of the energy partition between the rebound and the shock. Highly spherical cavitation bubbles are produced in microgravity, which suppresses the buoyant pressure gradient that otherwise deteriorates the sphericity of the bubbles. We measure the radius of the r...

The dynamics of a snow-ice cover is considered within the theory poroelasticity. modeled by three-phase medium consisting water, air and ice. governing equations are mass conservation for each phase with transitions, momentum in form Darcy’s law, equation whole system, rheological porosity heat balance snow. In full formulation liquid pressures functions temperature corresponding densities, vis...

The radial density of planets increases with depth due to compressibility, leading impacts on their convective dynamics. To account for these effects, including the presence a quasi-adiabatic temperature profile and entropy sources dissipation, compressibility is expressed through dissipation number, $\mathcal{D}$, proportional planet's radius gravity. In Earth's mantle, effects are moderate, b...

Determination of porosity, permeability, and pore volume compressibility of reservoir rocks and those variations with effective stress changes are of great interest in petroleum engineering. This paper has studied the influence of pore types of carbonate reservoir rocks on pore volume compressibility as well as Klinkenberg permeability and porosity at different stress values. In the current stu...

OBJECTIVE To explore triceps skinfold (TSF) compressibility and its associated factors among hospitalized patients. METHODS A cross-sectional study was conducted among hospitalized adult patients. Evolution of tissue compressibility during two seconds was registered and 120 TSF values were obtained using a digital calliper. Compressibility was determined according to the difference between th...

Abstract Soils containing significant levels of silt or clay generally exhibit unacceptable engineering properties (i.e. low strength, high compressibility and level volumetric changes) when exposed to variation in moisture content. Chemical stabilizers such as cement lime which are currently practiced, often high-priced unhygienic terms environmental sustainability. The prevailing study intend...

This paper reports density and speed of sound data for solutions of the ionic liquids (ILs) [C4mim]Cl and [C4mim][CF3SO3] in aqueous solution of 0.05 w/w amino acids of alanine, serine and proline at T = (288.15, 298.15, 308.15 and 318.15) K. From the experimental data measured, the apparent molar volume (Vϕ), isentropic compressibility ( ), and apparent molar isentropic compression ( ) have be...
