It must also have very low moisture content, in order to develop a concentration gradient
that will bring the residual moisture to the level required for further processing.
We determined their antioxidant activities by DPPH method after extracted the volatile oil of Basilicum polystachyon and the artificial antioxidants Trolox into 5 different concentration gradients
respectively, and then analyze the results by regression analysis.
Second, one must also account for the impact of lithium ion concentration gradients
on solution-phase potentials: a phenomenon known as concentration polarization.
To further discriminate the proteins involved in the S-nitrosylation process, membrane fractions of control, nitrite, and GSNO-treated hearts were subfractioned by linear concentration gradient
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.
The enclosure is subjected to vertical temperature gradient; the concentration gradient
is deduced from that of temperature.
There is a steep concentration gradient
for oxygen to diffuse from the alveoli (100mmHg) to the pulmonary capillaries (40mmHg).
Most commonly, a chemical source well created an attractant concentration gradient
via diffusion into an observation arena (8-11).
A higher capacity of column operation is established by continuously increasing concentration gradient
at the interface of the adsorption zone as it passes through the column while the concentration gradient
decreases with time in batch adsorption.
Contaminant transport in the plume and at the wall is driven by convective buoyant flows and lateral diffusion due to concentration gradient
at the boundary of the plume with room air.
The axial temperature gradient [partial derivative]T/[partial derivative]r and concentration gradient
[partial derivative]C/[partial derivative]z are assumed to be constant say A and B respectively.
