Penetration has long been recognized as an important factor
in the action of chemicals on plants. The effectiveness of herbicides
on such plants as blackberries is often thought to be limited by the
failure to obtain adequate penetration through the cuticular barrier.
A number of factors, among them relative humidity,...
The purpose of this work was to develop a dynamic partial order model of II electrolyte solutions which avoids inconsistencies present in the Debye-1-Iuckel and 1n related theories. It is shown that our results are consistent with activity coefficient data in aqueous electrolyte solutions. The main features of our work...
A high volume sampling system, employing Nuclepore filters and
designed for sampling particulate in the plumes from industrial
sources using a light aircraft, is described. The effluent of kraft
paper mills was sampled using this system and then analyzed by
electron microscopy.
Size distributions of particles were obtained at several...
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 purpose of this study was to explore some of the practices
of home economics teachers in the use of auxiliary personnel as
expressed by city and state supervisors. A second purpose was to
discover the beliefs of city and state supervisors regarding the use
of auxiliary personnel in home...
Extensive new trackline coverage of the Chile Trench between 23°S and 34°S, including more than 60 bathymetric and seismic reflection profiles across the trench axis, allows a much more detailed study of the tectonics and sedimentation of this feature than previously possible. Sediment distribution along the axis shows a remarkable...
