SUFFICIENT CONDITIONS ON DIFFUSIVITY FOR THE EXISTENCE AND NONEXISTENCE OF STABLE EQUILIBRIA WITH NONLINEAR FLUX ON THE BOUNDARY
(TEXAS STATE UNIVSAN MARCOS, 2012)
A reaction-diffusion equation with variable diffusivity and non-linear flux boundary condition is considered. The goal is to give sufficient conditions on the diffusivity function for nonexistence and also for existence ...
Diffusion phenomena of the oxygen and nitrogen in niobium by mechanical spectroscopy
(2010-05-19)
The short-range diffusion phenomenon (Snoek Effect) was investigated by mechanical spectroscopy measurements between 300 K and 650 K, in a polycrystalline niobium sample, containing oxygen and nitrogen, using a torsion ...
Taylor dispersion technique for investigation of diffusion in liquids and its applications.

Diffusion coefficients during osmotic dehydration of tomatoes in ternary solutions
(Elsevier B.V., 2004-02-01)
The apparent diffusion coefficients for sucrose, NaCl and water during osmotic dehydration of tomatoes in ternary solutions were determined. Long time experiments (up to 60 h) were carried out in order to determine equilibrium ...
Generic hyperbolicity of stationary solutions for a reaction-diffusion system
(PERGAMON-ELSEVIER SCIENCE LTD, 2010)
In this paper, we study the generic hyperbolicity of equilibria of a reaction-diffusion system with respect to nonlinear terms in the set of C(2)-functions equipped with the Whitney Topology. To accomplish this, we combine ...
