Study on Effective Diffusivity of Sea Cucumbers with Heat Pump Drying
Zhileng xuebao, 2018 The effective diffusivity is an important parameter for mass transfer research on the drying of sea cucumbers. The dependence of the effective diffusivity on temperature has been adopted in current studies, while the effects of moisture content and ...

Indirect Diffusion Effect in Degenerate Reaction-Diffusion Systems [PDF]
SIAM Journal on Mathematical Analysis, 2020 In this work we study global well-posedness and large time behaviour for a typical reaction--diffusion system, which include degenerate diffusion, and whose non-linearities arise from chemical reactions. We show that there is an {\it indirect diffusion effect}, i.e. an effective diffusion for the non-diffusive species which is incurred by a combination

Calculating effective diffusivities in the limit of vanishing molecular diffusion [PDF]
Journal of Computational Physics, 2009 In this paper we study the problem of the numerical calculation (by Monte Carlo Methods) of the effective diffusivity for a particle moving in a periodic divergent-free velocity filed, in the limit of vanishing molecular diffusion. In this limit traditional numerical methods typically fail, since they do not represent accurately the geometry of the ...

Effects of Proteins on Protein Diffusion [PDF]
Journal of the American Chemical Society, 2010 Despite increased attention, little is known about how the crowded intracellular environment affects basic phenomena like protein diffusion. Here, we use NMR to quantify the rotational and translational diffusion of a 7.4-kDa test protein, chymotrypsin inhibitor 2 (CI2), in solutions of glycerol, synthetic polymers, proteins, and cell lysates.

Diffusion effects in a superconductive model
Communications on Pure and Applied Analysis, 2014 A superconductive model characterized by a third order parabolic operator L" is analysed. When the viscous terms, represented by higher - order deriva- tives, tend to zero, a hyperbolic operator L0 appears. Furthermore, if P" is the Dirichlet initial boundary - value problem for L", when L" turns into L0; P" turns into a problem P0 with the same ...

Persistence effects in deterministic diffusion [PDF]
Physical Review E, 2009 In systems which exhibit deterministic diffusion, the gross parameter dependence of the diffusion coefficient can often be understood in terms of random walk models. Provided the decay of correlations is fast enough, one can ignore memory effects and approximate the diffusion coefficient according to dimensional arguments. By successively including the

Determination of Effective Moisture Diffusivity of Banana Using Thermogravimetric Analysis [PDF]
, 2014 Drying has been extensively used as a food preservation procedure. The longer life attained by drying is however accompanied by huge energy consumption and deterioration of quality. Moisture diffusivity is an important factor that is considered essential

Quantitative BOLD: The effect of diffusion [PDF]
Journal of Magnetic Resonance Imaging, 2010 AbstractPurpose:To make the quantitative blood oxygenation level‐dependent (qBOLD) method more suitable for clinical application by accounting for proton diffusion and reducing acquisition times.Materials and Methods:Monte Carlo methods are used to simulate the signal from diffusing protons in the presence of a blood vessel network.

Diffusion Effect in Quantum Hydrodynamics
Axioms, 2022 In this paper, we introduce (at least formally) a diffusion effect that is based on an axiom postulated by Werner Heisenberg in the early days of quantum mechanics. His statement was that—in quantum mechanics—kinematical quantities such as velocity must be treated as complex matrices.
