Modeling in Nuclear Waste Isolation: Approximate Solutions for Flow in Unsaturated Porous Media,diffusion equation, and poses some difficult numerical challenges. A special form of the hydraulic conductivity function however, results in a linear field equation for steady-state problems, for which a boundary integral method yields very fast solutions.

Similarity Solutions for Gravity-Dominated Spreading of a Lens of Organic Contaminant,ss with time. All solutions except that involving trapping can be carried over with minor modifications to the case of a lens simultaneously spreading and translating along a slightly inclined water table.

Mathematical Physics of Infiltration on Flat and Sloping Topography,Fully nonlinear solutions are developed, together with linearized solutions of certain problems. The nonlinear solutions involve either usefully convergent series or travelling waves. The linearizations use product solutions.

Autonomic Function and Electroacupuncture,or less) on the physical processes involved in precipitation. There are interesting questions of scale and measurement that pertain to these modeling efforts. Recent modeling efforts sum at including meteorological variables, and may be useful for regional down-scaling of general circulation models.

Nages Nagaratnam,Sai Adithya Nagaratnambe has warmed by about 0.5°C since the mid-nineteenth century. This is an important part of the evidence in the ‘global warming’ debate (Folland et al., 1990, 1992). How certain are we about the magnitude of the warming? Where has it been greatest? In this paper, these and related issues will be addressed.
