Sentence examples for diffusion of materials from inspiring English sources

This statement is equivalent to saying that diffusion of materials in metamorphism is a slow process, and various chemical units do not mix on any large scale.

Cell contained cross boundary diffusion of materials has been explained using valid formalisms and related analytical expressions have been developed.

Gap junctions are composed of arrays of intercellular channels and provide a route for the diffusion of materials of low molecular weight from cell to cell.

This can be explained by a known metabolic behavior: the cell contact with the outer medium increases to improve the diffusion of materials and waste.

Separating the choroid (the middle tunic of the globe) from the retina proper is a layer of pigmented cells, the pigment epithelium of the retina; this acts as a restraining barrier to the indiscriminate diffusion of material from the blood in the choroid to the retina.

In these, most nebular material still flows inward toward the sun; but near the midplane, the inward flow ceases or even reverses, letting the outward diffusion of material to the comet-forming region proceed.

These facts are possible since the outer wall of CNTs is protected by the AAO membrane, and the inner cavity is open, allowing the diffusion of material precursors dissolved in liquids and also in vapor phase.

We develop theory and numerical algorithms to apply level set methods to problems involving the transport and diffusion of material quantities in a level set framework.

Our work is in the spirit of some recent methods (D. Adalsteinsson, J. Sethian, Transport and diffusion of material quantities on propagating interfaces via level set methods, Journal of Computational Physics 185(1) (2003) 271 288; J.-J.

One disadvantage evident from the numerical simulations is that the maximum signal in open-well configurations is strongly dependent on the rates of secretion, as a result of persistent diffusion of material out of the wells.

Diffusion of material through gap junctions is stimulated by high intracellular sodium (Gandhi et al., 2009b), extracellular glutamate, quisqualate and kainate (Enkvist and McCarthy, 1994), and elevated levels of extracellular K+ (Enkvist and McCarthy, 1994; De Pina-Betalou et al., 2001).
