The existence of phase-separated states is an essential feature infinite-volume systems with a thermal, first-order phase transition. At energies between those at which the transition takes place, equilibrium homogeneous are either metastable or suffer from spinodal instability. In this range stable inhomogeneous, states. We use holography to investigate how picture modified finite volume in st...

We perform molecular dynamics simulations of the glass transition through isobaric and isochoric cooling of a model polymeric material. In general, excellent agreement between the simulation results and the existing experimental trends is observed. The glass transition temperature (Tg) is found to be a function of pressure under isobaric conditions and specific volume under isochoric conditions...

Abstract— In the present paper, we have investigated the high-pressure structural phase transition of cerium monopnictide. The three-body potential model has been used to study the structural properties of this compound. Phase transition pressures are associated with a sudden collapse in volume. The phase transition pressures and associated volume collapses obtained from present potential model...

This paper presents a numerical investigation of regime transition of flow of ellipsoidal particles and a comparison with that of spherical particle assembly. Particle assemblies constituting spherical and ellipsoidal particle of 2.5:1 aspect ratio are examined at separate instances in similar flow conditions in a shear cell model that is numerically developed based on the discrete element meth...

We have shown that the lattice fluid hydrogen bond ~LFHB! model can successfully quantify the first-order volume transition in hydrogels. The model predicts that a critical balance of hydrophilic and hydrophobic interactions is required for a gel to exhibit a discontinuous volume transition. In this work we will report the swelling behavior of a new thermoreversible copolymer hydrogel, which ha...

Background Non-nutritive sucking is part of the initial development process in preterm infants that may speed up the transition from the tube to oral feeding. The aim of this study was to evaluate the effect of non-nutritive sucking on mother's finger on feeding tolerance and attainment of independent oral feeding in preterm infants. Materials and Methods This single blind clinical trial was co...

BACKGROUND The diagnostic value of prostate volume results has been evaluated in patients with prostate problems of benign cause. METHODS For 247 patients, automated volume results were compared to manual results of planimetric reference volume and of the classical ellipsoid formula. Also, transition zone volume was estimated and growth curves of the prostate and prostate dimensions over age ...
