These were mounted t o permit withdrawal of fluid samples to determine the solute concentration gradient across the slot for the purpose of verifying the basic flow model.
Principal mechanism of vorticity generation in the braid region for a uniformly seeded flow, due to the misalignment of the particle concentrationgradient and the slip velocity.
Principal mechanism of vorticity generation in the braid region for a differentially seeded flow, due to the interaction between the particle concentrationgradient and the slip velocity.
These mechanisms are shown to be related to the misalignment of the concentrationgradient and the slip velocity, as well as to the difference in fluid and particle vorticities.
Spatially separated measurements of chemical concentration would allow the robot to determine the concentrationgradient and hence move towards the source.
They were able to metabolize radio-isotope labelled glucose and accumulate thiamine against a concentrationgradient.
All curves are averages over 1000 particle pairs and initially the concentrationgradient is uniform.
Other agents are also important in movement of this vitamin against a concentrationgradient, notably sodium ions and glucose.
These physical arguments then indicate that a positive bulk concentrationgradient favours a thicker film.
It seems likely that the parasites use the epidermal concentrationgradient of arginine residues for their navigation within the skin.
With ideal samples, scattering profiles from a concentrationgradient should be superimposable when scaled by concentration.
In this form, the driving forces for ion permeation are a concentrationgradient and an electrostatic potential gradient.
This instability is driven by the adverse concentrationgradient created by solute rejection at the solid-liquid interface.
By contrast, transport by diffusion does not require fluid flow but depends instead on the magnitude of the concentrationgradient and the diffusion coefficient.
The first term indicates that the vorticity will be altered if the concentrationgradient is misaligned with the direction of the slip velocity.
The concentrationgradient will not dissipate as long as the temperature gradient remains.
This concentrationgradient response was less evident in the other two species.
The resonant transition radiation from an electron charge that moves along the concentrationgradient of a cold isotropic plasma is calculated.
