The electrical cross-coupling between ions can markedly modify the diffusion process [55, 56].
Indeed, the energy of photons can be sufficient to produce nucleation centres, change the dynamics of the nuclei growth and modify the diffusion of species in the vapour phase.
For solving the later cited problem, and preserving the same context of using a sigmoidal function, we intend to modify the diffusion function to reach the joint goal namely good gray level and good sharp edge of the fault.
It was found that oxygen variation significantly modified the diffusion flame structure and the flame temperature, resulting in a substantial increase of soot.
(i) Alterations in the ECM could aberrantly modify the diffusion kinetics of paracrine factors such as growth factors, purines, etc., resulting in too much or too few of these factors reaching adjacent cells (57).
However, like SP-A, Mini-B also modifies the diffusion coefficients of all the micelle types (Table 1), although, interesting differences are found between how Mini-B interacts with SDS/DPC detergent micelles versus LMPC/LMPG lipid micelles.
In this paper we introduce an SA model implementation that deals with negative ˜ν values by modifying the source and diffusion terms in the SA model equation only when the working variable or one of the model closure functions become negative.
The solid contains trapping sites which modify the transient diffusion behavior.
In [3] Caputo modified the standard diffusion equation ∂ p ∂ t = k ∂ 2 p ∂ x 2. by introducing a fractional derivative (in the sense of Caputo) in Darcy's law [1] to take into account the memory effects that may prevail in the fluid.
In relation to a classical bulk thermolysis (390°C, 6 h) which affords branched waxy polymers, dilution with phenylether permits controlled diffusion reactions modifying the product characteristics: low molar masses, narrow distribution, high crystallinity, rich in α-olefins and few long branching formation.
