Abstract The influence of seasonally frozen ground (SFG) on water, energy, and solute fluxes is important in cold climate regions. hydrological role permafrost now being actively researched, but the SFG has received less attention. Intuitively, restricts (snowmelt) infiltration, thereby enhancing surface runoff decreasing soil water replenishment groundwater recharge. However, reported effects ...

The ATP-binding cassette (ABC) transporter superfamily is one of the most widespread of all gene families and currently has in excess of 1100 members in organisms ranging from the Archaea to manQ1. The movement of the diverse solutes of ABC transporters has been accepted as being strictly unidirectional, with recent models indicating that they are irreversible. However, contrary to this paradig...

The energetic properties of ternary Zr–Nb–Sn Zirconium-based alloy with concentration dissolved alloying elements ∼ 1 . 5 % are studied by using density functional theory. possibility additions separated different distances to dissolve/segregate in a host matrix is analyzed the help mixing energy and solute–solute binding energy. ability solutes trap single vacancy discussed studying formation ...

Low-solute hyponatremia is a relatively uncommon entity of euvolemic hyponatremia. Classic cases were described in alcoholics as beer potomania, which is characterized by hyponatremia in the setting of low-solute intake due to heavy beer drinking. We report a case of low-solute hyponatremia in a nonalcoholic person who was given a solute load, and, subsequently, had excessive diuresis with the ...

Solute transport in soils is commonly simulated with the advective-dispersive equation, or ADE. It has been reported that this model cannot take into account several important features of solute movement through soil. Recently, a new model has been suggested that results in a solute transport equation with fractional spatial derivatives, or FADE. We have assembled a database on published solute...

The Gibbs free energy of transferring a solute at infinite dilution between two solvents quantifies differences in solute-solvent interactions - if the transfer takes place at constant molarity of the solute. Yet, many calculation formulae and measuring instructions that are commonly used to quantify solute-solvent interactions correspond to transfer processes in which not the molarity of the s...

A finite-element approach was formulated, aimed at enabling an integrated study of mechanical and biochemical factors that control the functional development of tissue engineered constructs. A nonlinear biphasic displacement-velocity-pressure description was combined with adjective and diffusive solute transport, uptake and biosynthesis. To illustrate the approach we focused on the synthesis an...

We address the following problem: Given a simple polygon $P$ with $n$ vertices and two points $s$ and $t$ inside it, find a minimum link path between them such that a given target point $q$ is visible from at least one point on the path. The method is based on partitioning a portion of $P$ into a number of faces of equal link distance from a source point. This partitioning is essentially a shor...

Transport of a sorbing solute in a two-dimensional steady and uniform flow field is modeled using a particle tracking random walk method. The solute is initially introduced from an instantaneous point source. Cases of linear and nonlinear sorption isotherms are considered. Local pore velocity and mechanical dispersion are used to describe the solute transport mechanisms at the local scale. The ...

The permeability of a membrane to solute penetrants is well defined on the linear response level simply as ratio penetrants’ flux and concentration gradient at boundary layers. However, nonlinearities emerge in flux–force relation j(f) for large driving forces f, which definition becomes ambiguous. Here, we study nonequilibrium permeation orchestrated by generic force using penetrant- monomer-r...
