When grain growth is governed by the mobility of triple junctions the kinetics change, and the von Neumann Mullins relation does not hold anymore.
Thus, the flow stress gradually becomes not governed by the mobility of screw dislocations (as determined by the critical resolved shear stress), giving rise to the weak temperature sensitivity of the flow stress.
The process of grain growth in 2D systems is analyzed with respect to the controlling kinetics: from solely boundary kinetics, when grain growth in a polycrystal is determined by the Von Neumann Mullins relation, to exclusively triple junction kinetics, when grain growth is governed by the mobility of triple junctions.
These parameters are governed by the mobility model.
Growth velocity governed by the mobility of the interface as expressed by Eq. (3) .
Fluid saturations vary during the test and their distribution in time is governed by fluid mobilities and effective permeabilities; additionally, gravitational forces, thermal gradients and capillary pressures may also strongly affect the flow.
In the standard GTAP model, the mobile endowment commodities are perfectly mobile across industries within each region; and the sluggish endowment commodities are imperfectly mobile, with the degree of mobility governed by an elasticity of transformation function in the GTAP model.
Physical stability, however, is governed by thermodynamics and molecular mobility.
From infrared and impedance spectroscopic studies, it is inferred that conductivity is governed by charge carrier density, ionic mobility and diffusion coefficient for PVA incorporated with 10 40 wt.% LiBOB.
The levels and occurrence of residues in fish samples seem to be governed by feeding mode, age and mobility of the biota, consequently, higher concentrations of pesticide residues oberved in Clarias gariepinus may be attributed to the feeding mode of the fish (Mwevura et al., 2002).
Atomic mobility is then governed by two parameters: activation energy Uel (0.92 eV) and correlation factor χ (0.39).
