Macroscopic water vapor diffusion is not enhanced in snow [PDF]

The Cryosphere, 2021
Water vapor transport in dry snowpacks plays a significant role for snow metamorphism and the mass and energy balance of snowpacks. The molecular diffusion of water vapor in the interstitial pores is usually considered to be the main or only transport ...

A Multiscale Approach to Brownian Motors [PDF]

, 2005
The problem of Brownian motion in a periodic potential, under the influence of external forcing, which is either random or periodic in time, is studied in this paper. Multiscale techniques are used to derive general formulae for the steady state particle

Nonlinear and Linear Equation of Gas Diffusion in Coal—Theory and Applications

Applied Sciences, 2021
The authors derived the analytical solution to diffusion equations. The solution requires linearization of diffusion equations, as well as developing the obtained expression into a series.

Kinetic description of particle interaction with a gravitational wave [PDF]

, 1997
The interaction of charged particles, moving in a uniform magnetic field, with a plane-polarized gravitational wave is considered using the Fokker-Planck- Kolmogorov (FPK) approach.

Research on the Diffusion of Vs55 Permeability in Rat Kidneys Based on Computer Tomography

Zhileng xuebao, 2020
Cryopreservation is the usual method for long-term preservation of natural and engineered tissues. However, homogeneous loading of tissues with CPAs constitutes one of the major hurdles in tissue cryopreservation.

Fast manometric method for determining the effective oxygen diffusion coefficient through wine stopper

Polymer Testing, 2021
A fast manometric method has been designed for determining the oxygen transfer rate through cork stoppers. Thanks to this technique, it is possible to measure the effective diffusion coefficient of oxygen through a thin cork wafer in a few days, whereas ...

Diffusing proteins on a fluctuating membrane: Analytical theory and simulations

, 2010
Using analytical calculations and computer simulations we consider both the lateral diffusion of a membrane protein and the fluctuation spectrum of the membrane in which the protein is embedded.

Transport of Cosmic Rays in Chaotic Magnetic Fields [PDF]

, 2001
The transport of charged particles in disorganised magnetic fields is an important issue which concerns the propagation of cosmic rays of all energies in a variety of astrophysical environments, such as the interplanetary, interstellar and even extra ...
