This is a fundamental study of the mechanism of protein particle
removal during flow through sandy soil. Mathematical models for
diffusion-adsorption and diffusion-convection-adsorption processes
were developed and compared with experimental data. An attempt was
made to calculate the distance over which the adsorption forces act.
The differential equation for the...
The purpose of this study was to investigate the use of therapeutic
self-directive play as a means of developing positive self-concepts
and motivation of educationally handicapped children.
Further consideration was also given to behavioral changes as viewed
by the classroom teacher and aide. The population of the study consisted
of...

Micropaleontological data have been analyzed through mathematical
and statistical procedures, in order to: (1) establish the distribution
pattern of radiolarian assemblages in the surface sediments,
(2) establish the relationship of these assemblages with oceanographic
variables, (3) determine the faunal composition down-core with
respect to the faunal surface pattern, and (4)...
The distribution patterns of quartz and opal contents and the distribution
patterns of radiolarian assemblages, in the sediments of the
southeastern Pacific, are largely controlled by both the surface winds
and the mixed-layer oceanic circulation. The distribution pattern of
quartz is related to eolian and ice-rafted transport, as well as...
