The continuation of conductive temperature fields is being
considered. The continuation of a field involves the extrapolation of a
field known over a limited domain to an adjacent domain in such a way
that it satisfies the heat conduction differential equation and other
imposed constraints. Continuations forward in time and...
The numerical analysis of thermal convection in porous media,
heated from below, and assuming Darcy flow conditions, involves the
solving of a set of non-linear equations for the temperature and flow
fields. The condition of criticality determining the onset of convection
is obtained by linearization and the solving of an...
Anomaly timescales for the last 90 million years, derived from
marine magnetic profiles and published prior to mid-1979, are summarized,
illustrated for comparison, and critically reviewed. A revised timescale
is constructed using calibration points which fix the ages of anomalies
2.3', 5.5, 24, and 29. An equation is presented for...
A general theory of micromorphic materials was developed by
Eringen for the prediction of continuum behavior of materials with
inner structure, such as, granular solids, composite materials,
anisotropic and polymeric fluids. Recently Eringen derived balance
laws of micromorphic mechanics from a different point of view. His
derivation of the master...
Fish farming has grown very rabidly during the past few decades. One component of this expansion is the introduction of new species, previously unknown to most consumers, to world markets. Arctic char, a cold water salmonid, is one of these species. In 1987, the total commercial supply only amounted to...
The thermal regime of a postulated descending lithospheric slab
is calculated. The gravity anomaly associated with such a structure
is large in amplitude and long in wavelengh. Observed free-air
gravity anomalies in the Pacific Northwest do not indicate a gravitational
effect due to a descending slab.
Two hypothetical compensation models...
