The dehydration process was described by an osmotic diffusion model based on mass transfer through cellular membranes and the diffusion of different species through intercellular spaces.
A one dimensional model for a μPSC based on mass balances of species in the anode and cathode chambers considering unsteady one dimensional diffusion is developed.
The theoretical models are based on mass, momentum, and energy conservation equations, and divided into boundary layer models and diffusion layer models.
"The Second Wave Society is industrial and based on mass production, mass distribution, mass consumption, mass education, mass media, mass recreation and entertainment," Toffler said in a 1999 interview.
Echo-planar DWI can help to differentiate between benign and malignant orbital masses based on apparent diffusion coefficient (ADC) values.
A mechanism for peptide oxidation was proposed based on a diffusion control of mass transport and the formation of adsorbed layers able to mediate electron transfer.
Current model predictions for the effect of the diffusional relaxation mechanism are based on a diffusion coefficient for the mass transport along the matrix-reinforcement interface.
In the case of wet products such as paint, it is necessary to take into account gas-phase mass transfer, which is based on molecular diffusion across a laminar boundary layer as described in eq 24.
A mathematical model based on external mass transfer and pore diffusion was used for the prediction of mass transfer coefficient and effective diffusivity of metals in macro-fungi bed.
Partial differential equations were derived to describe the mass transfer of each adsorbate based on pore diffusion in the adsorbent as a major rate controlling mechanism.
