While there are numerous publications that report diffusion changes in response to particular, histologically confirmed tissue abnormalities in animal models of disease, the microscopic correlates of altered diffusion parameters due to neurological disorders in humans have been difficult to characterize.
The porosity of the hydrogels produced, as shown by protein diffusion, increases in response to changes in the pH and the ionic strength of the external medium.
Braginsky and Le Mouël (1993) and Jault and Le Mouël (1994) have examined the effect of such a thin layer in which the flow is driven by a dynamics distinct from that within the underlying volume of the core and claimed that a significant diffusion occurs in response to fluctuations of horizontal flow therein.
Accordingly, it will be useful, in future work, to examine changes in internal root, stem and leaf anatomy, including the formation of aerenchyma (the snorkel-like conduits for gas diffusion; Kordan 1974) in response to rising floodwater and their contribution to leaf photosynthesis, plant respiration and root aeration as possible flood-avoidance traits.
The formation of complexes with cations leads to mediate their transport across the cell membrane in response to diffusion gradients.
This value was estimated from measurements of the individual FcγR-IgG binding free energy Δ F LR ≈ 20 k BT [ 78- 81], the average density d LR = 270 - 435 μm-2 of IgG-FcγR bonds [ 82], and the fact that in response to diffusion and trapping or signaling, receptors may cluster at the cup.
The stress produced can be hyperosmotic in which cells shrink due to fluid diffusion to the exterior of the cell or hypoosmotic in which cells swell and burst in response to fluid diffusion into the cell.
The diffusion of pottery traditions, which arise in response to the need to store and cook grains, shows evidence of the influences from northwest and northeast, with the western influence predominating over much of the country.
The arrest by Spanish police was made in response to a Russian "diffusion order" distributed to member states through Interpol databases.
MPI signals can be generated from a combination of Néel relaxation, Brownian rotational diffusion, and hysteretic reversal mechanisms of NPs in response to applied magnetic fields.
