Computer control of a robot arm's motion requires kinematic algorithms for relating the state of a particular arm's joints to the position and orientation of its tool in three-dimensional space. To design such algorithms requires mathematical formulation of the kinematics of the arm. The resulting long, tedious algebraic manipulations suggest...
The induction of drug-metabolizing enzymes is a
complex biochemical process manifested not only by
increases in various cytochrome P-450 isozymes and
related activities, but also by alterations in
endoplasmic reticulum membranes. Little work has been
done to examine how cytochrome P-450 inducing agents
influence other cellular processes, such as
phospholipid...
Women today represent a larger part of the American workforce
than ever before. The influx of women into the workplace raises
questions about differences in male and female work-related behaviors
particularly in groups, and decision making. For example, existing
research suggests that men and women have differing strategies in
groups...
High hydrostatic pressure processing (HPP) is a nonthermal process in which foods are subjected to pressures in the range of 100-700 MPa at room temperatures or higher. HPP is effective in reducing microbial counts and enzyme activity. The ability of HPP to modify the functional properties of proteins has become...
This exploratory investigation focused on the validity of the concepts of high-context and low-context as a meaningful and powerful construct for examining cultural differences. Specifically, American and
Japanese value differences and communication patterns were examined.
The study tested the hypotheses that Japanese students would rank
high-context group orientation values higher...
We examine variability observed in heat flow determinations collected on hot spot
swells. We find substantial scatter in heat flow at wavelengths of a few hundred kilometers
and less at both Hawaii and Reunion, where closely spaced data exist, and large variability
in the regional heat flow surveys at Cape...
This study addressed the incidence of drug use by
freshmen at Siuslaw High School in Florence, Oregon, and
sought their opinions about effective drug and alcohol
prevention programs. The purpose was to provide basic data
which would ultimately assist in specific drug and alcohol
programs for this population.
In phase...
A sensitive technique for the determination of As(III) and As{V)
at μ/L and sub-μg/L concentrations from a single sample aliquot
has been developed. This technique is based on the hydride
generation atomic absorption (HGAA) spectrophotometry. The hydrides
of the arsenic species are generated in a reaction vessel by mixing
the...
Ten species of bats occur in the Oregon Coast Range and are hypothesized to be
associated with late-successional forests. The development of characteristics of late-successional
forests in young forest stands can be accelerated through silvicultural
practices such as thinning I examined the effects of thinning on the use of forests...
