This retardation was attributed to diffusion of the flowing solute into the closed and dead-end pores (matrix diffusion).
Hence two on-line capillary electrophoretic methods for studies of β-secretase activity based on the principles of transverse diffusion of laminar flow profiles and electrophoretically mediated microanalysis were developed, both using a simple unlabeled peptide substrate and UV detection.
In the present study the phenomenon of mixing by convection and diffusion of two flow streams with inlet scalar concentrations of zero and unity in the two halves of a tube perpendicular to the plane of curvature has been reported.
The acquired experimental data indicate that the process of NP binding to a targeted surface is a synergic result of many factors, including the shape and diffusion of NPs, the flow effects [17, 19], as well as binding and internalization kinetics [20].
Peaks were fitted mathematically using a combination of the Rankin equation to model the peak broadening effects of variable pore sizes within any one gel filtration resin [33], and work to model the peak broadening effects of diffusion and inhomogeneity of flow [34].
Additionally, tissue oxygenation depends on adequate arterial oxygenation and total blood flow, diffusion of oxygen across capillaries and the distribution of microcirculatory flow.
This raises the question if cytoskeletal transport alone is sufficient to account for mRNA localisation (Glotzer et al., 1997; Forrest and Gavis, 2003) and highlights the importance of distinguishing its contribution to localisation from the contribution of flows and diffusion (Serbus et al., 2005).
The movement of smoke; the diffusion and flow of coloured water, mercury, oil, and so on; pneumatic inflation and deflation; and the movement of masses of bubbles have all served as media for kinetic sculpture.
Ziabakhsh et al. [25] studied the problem of flow and diffusion of chemically reactive species over a nonlinearly stretching sheet immersed in a porous medium.
This switch prevents the unwanted diffusion of the proposed curvature flow approach.
