Dexamethasone levels and base-to-apex concentration gradients
in the scala tympani perilymph after intracochlear delivery in the guinea pig.
 that a concentration gradient
can either increase or decrease the tendency towards DDT with the decisive factor being the obstacle geometry.
It is presumed that the average diffusion distance x is proportional to the tubulin concentration gradient
length L; then
Influence of pH and Concentration Gradient
on the Tunable Ionic Current Rectification Performances.
The model took into account both the diffusion under concentration gradient
and potential gradient and active transport which was ATPase enzyme mediated, and appropriate partial differential equations for the two mechanisms of transport had been derived and were solved by iterative methods.
The heat and mass transfer rates at the wall are related to the temperature and concentration gradients
at the wall are, respectively,
The slowly crystallizing polymer with the highest molecular mass, being closest to its equilibrium melting point, cannot form spherulites anymore, owing to the high concentration gradient
of salt in the amorphous surrounding (Fig.
2,1 entails an interesting conclusion: regardless of the aforesaid effects related to [delta]m that possibly alter the plain diffusion process, the time evolution of the system is actually consequence of the concentration gradient
law; although the Fick hypothesis does not contain explicit reference to the time, this latter enters indeed into the problem through v.
This innate electrical signaling system regulates bodily functions from the cellular level by using the movement of ions with a small positive or negative electrical charge to create concentration gradient
and consequently an electric potential gradient.
Such system becomes unstable when heated from below and generates solute concentration gradient
known as the Soret effect, which is characterized by the separation parameter N, proportional to the thermodiffusion coefficient.
: For a gas or liquid, diffusion occurs where there is a difference in pressure or concentration between two different areas.
Most commonly, a chemical source well created an attractant concentration gradient
via diffusion into an observation arena (8-11).
