Autonomy-supportive parenting appears to play an important role in children's executive function (EF) development. However, few studies have accounted for parents' EF skills when examining the link between parenting and child EF in families from diverse socioeconomic backgrounds. In the current study, parents and their 3- to 5-year-old children (N...
In plywood manufacture, the interaction of wood with
resin during hot pressing is responsible for the
development of glue bond strength and hence panel quality.
In this study, temperature and vapor pressure distributions
and compaction of laminates were measured during pressing.
Analysis of these factors emphasized boards formed under
conventional...
Microtus canicaudus Miller, the gray-tailed vole, was studied
in the field and laboratory in order to clarify aspects of the relationship
of this species to its habitat. All trapping and sampling was done
on permanent pasture land in the William L. Finley National Wildlife
Refuge 12 miles south of Corvallis,...
The usefulness of preplant nitrogen (N) in establishing
alfalfa in colder production areas has not been
well characterized. This study was conducted to determine
the effect of preplant N and soil temperature on
yield, percent N derived from biological nitrogen fixation
(PBNF), and shoot N concentration in alfalfa (Medicago
sativa...
Blood, liver, kidney, femur, and ovaries were assayed
from female Wistar rats following oral administration of
uranyl nitrate. Three uranium concentrations were
studied for six time periods ranging from 4 hours to 240
hours following gavage. Uranium burdens of tissues were
determined by neutron activation and delayed fission
neutron counting...
Delayed neutron counting (DNC) is a variation of neutron activation analysis applicable only to fissionable elements. Briefly, it
involves exposing a sample to the neutron flux in a reactor to induce
fission, then quickly retrieving the sample to count the delayed
fission neutrons emitted. These are proportional to the amount...
The semiconductor gallium arsenide (GaAs) has many potential
advantages over the more widely used semiconductor silicon (Si).
These include higher low field mobility, semi-insulating substrates,
a direct band-gap, and greater radiation hardness. All these
advantages offer distinct opportunities for implementation of new
circuit functions or extension of the operating conditions...
A growth model is developed for coho salmon which accounts for
temperatures and feeding rates typically encountered in fish hatchery
operation. Feeding rates utilized by the model ranged from
maintenance to maximum utilizable rations. The model is derived from
an empirical equation for maximum growth rate, and a theoretical
equation...
The fire regimes of a 9,000 hectare study area on the east side of the Southern Oregon Cascades are described. Fire regime parameters included are frequency, extent, and predictability of fire return interval. Severity of two fires is mapped by type of evidence. Changes in fire regime due to fire...
The settlement history of a remote area in the Coast Range of Oregon, from the 1870s to the 1930s, is examined through factors that may have influenced the success or failure, and length of residence of the homesteaders and later residents. Despite the rugged and isolated location, a small community...
