This investigation was designed to determine the general achievement,
ability to solve applied problems, and attitude toward the role of
mathematics in science of college calculus students grouped in an
experimental class according to academic major during their first
three terms. The subgroups were biology-business, mathematics,
and science-engineering majors. The...
Fourier techniques have recently become popular for the
description of underwater image transmission. Two properties
necessary for the application of Fourier techniques to any system
are those of linearity and invariance. This work describes a
laboratory investigation of these properties for a variety of
aqueous media. The hypothesis is found...
The conceptual framework of an erosion model has been designed to link processes of mass wasting, surface erosion, and channel storage and transport. A program to stimulate mass wasting will be based on a variation of the factor of safety approach which balances forces tending to drive mass movement against...

In a series of 30 winter wheat fertilizer experiments conducted in the Willamette Valley between 1963 and 1969, optimum rates of nitrogen fertilization varied from 75 to 150 pounds per acre. Fertilization with N, particularly at the-higher rates, increased the protein content of the grain.
Spring-applied N gave greater yield...
The ability of mercury to inhibit β - galactosidase activity from
cell-free extracts of Streptococcus lactis, Escherichia colt and
intestinal homogenates of hogs, female rats, and humans was studied. Mercuric acetate was added in vitro to all sources of β - galactosidase except for the rats, which were placed on...
Public Trust Doctrine. is a legal theory substantive enough for private citizens to utilize as a comprehensive legal approach to resource management problems. The doctrine is ultimately derived from the notion of governmental responsibility to hold lands in trust for beneficial use by the public.
The governmental title to lands...
The genus Lichnanthe Burmeister contains eight extant and one
fossil species which are strictly nearctic in distribution. The
subfamily Glaphyrinae, however, is distributed nearly world-wide.
Five species were previously described and three are described as
new herein. All eight extant species are described in detail herein,
synonomies are made current,...
The purpose of this study was to contrast the effectiveness of
computer-assisted ear-training instruction with the traditional style
of ear-training instruction to determine if computer-assisted instruction
increased the students' ability to identify auditory stimuli utilized
in Basic Musicianship at a rate different from that of the traditional
methodology.
Procedures
