Effect of clays and metal containers in retaining Sm3+ and ZrO2+ and the process of reversibility
(Walter de Gruyter, 2014)
Knowledge and understanding about radionuclides retention processes on the materials composing the engineered barrier (clay mineral and metallic container waste) are required to ensure the safety and the long-term performance ...

Analysis of nonlinear transport in Couette flow
(American Physical Society, 1989)
The nonlinear Bhatnagar, Gross, and Krook [Phys. Rev. 94, 511 (1954)] kinetic equation is solved for boundary conditions leading to planar Couette flow and heat transport. In the limit of zero Knudsen number but arbitrary ...

Glasslike relaxation in a one-dimensional bonded-fluid model
(American Institute of Physics Publising LLC, 1991)
A Monte Carlo investigation of the linear and nonlinear relaxation of a one-dimensional bonded fluid is presented. The simulation shows that the model possesses many of the qualitative properties of the glass-forming ...

On the approximate and null controllability of the Navier-Stokes equations
(Society for Industrial and Applied Mathematics, 1999-06)
This paper presents some known results on the approximate and null controllability of the Navier–Stokes equations. All of them can be viewed as partial answers to a conjecture of J.-L. Lions.

Self-diffusion in freely evolving granular gases
(American Institute of Physics, 1994)
A self-diffusionequation for a freely evolving gas of inelastic hard disks or spheres is derived starting from the Boltzmann–Lorentz equation, by means of a Chapman–Enskog expansion in the density gradient of the tagged ...

The primitive model of ionic fluids near its critical point in the Poisson–Boltzmann and modified Poisson–Boltzmann theories
(AIP Publishing, 1994-02)
The Poisson–Boltzmann (PB) and modified Poisson–Boltzmann (MPB) theories are used to investigate the primitive model of ionic fluids in the low density–large coupling regime where the liquid–vapor transition is situated. ...

Monolayer arrangement of fatty hydroxystearic acids on graphite: Influence of hydroxyl groups
(Elsevier, 2013)
Previous studies have indicated that long-chain linear carboxylic acids form commensurate packed crystalline monolayers on graphite even at temperatures above their melting point. This study examines the effect on the ...

Residual properties of a two-level system
(American Institute of Physics Publising LLC, 1991)
The residual properties, after cooling from a high temperature to T=0 K, of a system of identical and independent two-level systems are analyzed. A general criterion to know whether a given cooling law will lead to a ...
