the thermal diffusion factor, at, for a binary gas mixture is calculated on the basis of nonequilibrium thermodynamics. a new formula for at is derived and this factor is given for several paris of gases according to this formula.

We present results of computer studies of the spatial correlations in two nonequilibrium model systems. These are lattice gases on 2' described by (apparently) nonGibbsian probability measures which are stationary with respect to simple, anisotropic, particleconserving stochastic dynamics. The translation-invariant pair correlation functions G(r) are found to decay like a quadrupole field, i.e....

The Brazilian incubation movement, despite having grown 25 percent in the last ten years, is going through a phase of stagnation due to lack of harmony between their structures and services to the new demands of society and the economic moment. Due to this fact, the Porto Digital Management Unit (NGPD), the institution responsible for the Porto Digital Technology Park governance in Recife – Bra...

How to accurately probe chemically reactive flows with essential thermodynamic nonequilibrium effects is an open issue. Via the Chapman-Enskog analysis, local particle velocity distribution function derived from gas kinetic theory. It demonstrated theoretically and numerically that depends on physical quantities derivatives, independent of chemical reactions directly. Based simulation results d...

The transport and fate of many contaminants in subsurface systems can be influenced by several rate-limited processes, such as rate-limited sorption, diffusional mass transfer, and transformation reactions. Identification of the controlling process in such systems is often difficult, and is confounded by the possible influence of additional factors such as nonlinear or hysteretic sorption. We p...

Nonequilibrium conditions due to either allopatry followed by secondary contact or recent range expansion can confound measurements of gene flow among populations in previously glaciated regions. We determined the scale at which gene flow can be estimated among breeding aggregations of bullfrogs (Rana catesbeiana) at the northern limit of their range in Ontario, Canada, using seven highly polym...

Depinning and nonequilibrium transitions within sliding states in systems driven over quenched disorder arise across a wide spectrum of size scales ranging from atomic friction at the nanoscale, flux motion in type II superconductors at the mesoscale, colloidal motion in disordered media at the microscale, and plate tectonics at geological length scales. Here we show that active matter or self-...

We prove that incompressible two-dimensional nonequilibrium Langevin dynamics (NELD) converges exponentially fast to a steady-state limit cycle. use automorphism remapping periodic boundary conditions (PBCs) such as Lees–Edwards PBCs and Kraynik–Reinelt treat respectively shear flow planar elongational flow. The convergence is shown using technique similar (Joubaud et al. in J Stat Phys 158:1–3...
