This thesis introduces a technique for approximating to a desired
degree of accuracy a linear parabolic equation of two spatial
dimensions with given initial data and prescribed boundary conditions.
The technique is generalized to non-linear parabolic equations.
It is stable for all mesh ratios, and it is second order accurate...
The study of water movement in unsaturated soils by using appropriate
diffusion equations has attracted considerable attention in
recent years.
In this study, a numerical technique is developed for solving
a generalized, dimensionless diffusion equation by the use of a digital.

The mycorrhizal rootlets of Douglas-fir (Pseudotsuga menziesii (Mirb.) Franco.) and red alder (Alnus rubra Bong.) were extensively investigated. A jet-black mycorrhiza was found to be dominant on Douglas-fir rootlets. The fungal symbiont was identified as Cenococcum graniforme (Sow.) Ferd. and Winge. Two forms of mycorrhizae predominated on root systems of...
