The computed results indicate that, with the increment of the cooling rate, the dendritic growth velocity increases, both the main branch and side-branches become slender, the secondary dendrite arm spacing becomes smaller, the inadequate solute diffusion in solid aggravates, and the severity of microsegregation ahead of interface aggravates.
Restricted main root length was due to inadequate O2 diffusion to the root tip in waterlogged soil.
These include the susceptibility to digestive enzyme degradation, instability in the acidic pH environment, poor mucus diffusion and inadequate permeation through the gastrointestinal epithelium.
It is now well-known that Fick's law is frequently inadequate for describing moisture diffusion in polymers and polymer composites.
The effectiveness of chemotherapeutic drugs is further reduced by inadequate delivery and limited diffusion through different microenvironments (Jain, 1999; Tannock et al, 2002; Minchinton and Tannock, 2006).
Abnormal and inadequate vasculature coupled with diffusion limitation results in reduced availability of nutrients, for example glucose and oxygen (Jain, 1988; Vaupel et al, 1989).
Its failure at lower densities suggests that the molecular dynamics computer result of self-diffusion is inadequate for describing the effect of collective molecular motion encountered in tracer diffusion across the entire density range.
In contrast, few lung units are recruitable in diffuse pulmonary fibrosis: DLCO and its components are not only reduced at rest but fail to rise as Q̇ increases (19); inadequate recruitment causes the diffusion-to-perfusion (D/Q̇) ratio to fall with exercise, leading to severe arterial hypoxemia (7).
A diffusion description is inadequate in this situation.
In this case, non-coupled pure gas diffusion equations are inadequate for description of CO2 CH4 mixture diffusion.
