Usually, water diffusion
curves of a coating obey Fick's law with a diffusion step followed by a second step that is a saturation plateau.

The mechanisms of water diffusion
into the swelled hydrogel were investigated by (4).
In the second episode of psychosis, recurrent water diffusion
and continued neuroinflammation lead to axonal damage and more serious neurodegeneration.
Bulk water diffusion
is characterized by one constant, the apparent diffusion constant (ADC).

in multiple sclerosis lesions and normal-appearing white matter using echo-planar imaging," Archives of Neurology, vol.
Other key processes such as water diffusion
, ion exchange (inter-diffusion) and precipitation of secondary minerals (i.e., clays, zeolites, etc) may be important in the long-term and they may occur in parallel to glass matrix corrosion.
It is assumed that the water diffusion
inside the load is instantaneous, and surface evaporation affects the thermal field problem through its boundary conditions.
It is frequently reported in the literature that the water diffusion
coefficient in different epoxy systems is around [10.sup.-8] to [10.sup.-10] [cm.sup.2]/s.
