Abstract Solute transport under single-phase flow conditions in porous micromodels was studied using high-resolution optical imaging. Experiments examined loading (injection of ink-water solution into a clear water-filled micromodel) and unloading water an filled micromodel). Statistically homogeneous fine-coarse patterns were used. It is shown that the time scale during larger than loading, ev...

Water and solutes transport in epithelial tissues is an important mechanism for maintenance of the homeostasis of internal environment; volume and composition of extracellular fluid. Molecular technologies and advancement of the genome projects have identified plenty of membrane proteins that mediate epithelial transport. Membrane transport proteins can be classified into channel, solute carrie...

Solute transport in streams is governed by a suite of hydrologie and chemical processes. Interactions between hydrologie processes and chemical reactions may be quantified through a combination of field-scale experimentation and simulation modeling. Two mathematical models that simulate conservative and nonconservative solute transport in streams are presented. A model for conservative solutes ...

Accurate assessment of the fate of salts, nutrients, and pollutants in natural, heterogeneous soils requires a proper quantification of both spatial and temporal solute spreading during solute movement. The number of experiments with multisampler devices that measure solute leaching as a function of space and time is increasing. The breakthrough curve (BTC) can characterize the temporal aspect ...

The escape of solutes from the blood during passage along capillaries in heart and skeletal muscle occurs via diffusion through clefts between endothelial cells and, for some solutes, via adsorption to or transport across the luminal plasmalemma of the endothelial cell. To quantitate the rates of permeation via these two routes of transport across capillary wall, we have developed a linear mode...

8 9 The objective of this work is to discuss solute transport phenomena in fractured porous 10 media, where the macroscopic transport of contaminants in the highly permeable inter11 connected fractures can be strongly affected by solute exchange with the porous rock 12 matrix. We are interested in a wide range of rock types, with matrix hydraulic 13 conductivities varying from almost impermeabl...
