An in vitro study was conducted to investigate the metabolism and distribution of Se⁷⁵-selenite and Se⁷⁵-selenomethionine (SEM) in
chick blood. Se⁷⁵-selenite is taken up by RBC (13% within 20
minutes) and expelled into the plasma to become bound to proteins. In
contrast, Se⁷⁵-SEM showed a more gradual and continuous buildup...
A Resource Planning and Management System (RPMS) and Goal
Programming algorithm are integrated into a tool for optimization of
resource allocation in university academic departments. The integrated
approach is then applied to the management models of the
Industrial and General Engineering Department at Oregon State
University and of the Industrial...
Forests play an integral role in the global carbon cycle, regulating the atmospheric CO₂ concentration by sequestering nearly one third of anthropogenic carbon emissions and storing carbon for centuries. Forest ecosystems are integrated into the culture, ecology, and economy of western North America, supporting wildlife habitat, local economies, recreation, and...
Biomass burning is a significant contributor to atmospheric carbon emissions but may also provide an avenue in which fire-affected ecosystems can accumulate carbon over time, through the generation of highly resistant fire-altered carbon. Identifying how fuel moisture, and subsequent changes in the fire behavior, relates to the production of fire-altered...
The free amino acid content of the intracellular pools in higher
marine fungi was determined by thin-layer and gas-liquid chromatography.
The organisms investigated include:
Ascomycetes; Nais inornata, Leptosphaeria oraemaris, Corollospora
maritima, Haligena elaterophora, Halosphaeria mediosetigera, Halosphaeria
appendiculata, Halosphaeria quadriremis, Lignincola Laervis
and Remispora hamata, and Fungi Imperfecti; Zalerion maritimum and...
Recent emphasis on range improvement of sagebrush-bunch-grass
types in Oregon has underscored the need for better understanding
of their importance to deer winter range management. The
objectives of this study were to evaluate the impact of various sagebrush
control practices on the composition, production, and utilization
of deer forage plants...
A novel mode of shallow aquifer management could increase the volumetric potential and distribution of underground, freshwater storage: Shallow aquifer storage and recovery (SASR). In this mode, water is efficiently stored in basin fill aquifers with strong hydraulic connection to surface water. Regional numerical modeling can provide a linkage between...
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...
Since the isolation of the Oregon sockeye salmon virus (OSV) in
1958, extensive investigations have been undertaken to characterize
the properties of this virus. The results of these investigations
have indicated that OSV is a single-stranded RNA virus which contains
essential lipids and has a density of 1.16 gm/cm³ in...
Gram positive cocci isolated from Oregon wines
were characterized and their relative malate fermentation
abilities compared. They were heterofermentative,
catalase negative, and facultatively anaerobic. Glucose,
fructose, cellobiose, maltose, ribose, trehalose, salicin
and esculin were fermented by all strains. Arabinose was
fermented weakly but lactose, raffinose, sucrose, xylose,
rhamnose, mannose and...
Thermo-hygro-rheology of wood-adhesive systems plays an important role during the hot pressing process of wood based composites. The principal objective of this research is to quantitatively study the thermo-hygro rheological characteristics of wood-adhesive systems used in such composites. This is with a view to providing material characteristics which may be...
This paper evaluates Oregon Statewide Planning Goal 5: Natural Resources and Goal 17
Coastal Shorelands, planning programs and makes recommendations for improvement to the
Oregon members of the Columbia River Estuary Study Task Force (CREST). CREST is a
Council of Governments formed in 1974 which includes the local counties, cities...
Efforts to directly control the amount and timing of residential
growth in Aumsville, Oregon, were unsuccessful in receiving approval
from the Land Conservation and Development Commission (LCDC) at a series
of public hearings in 1978. A review of the issues raised at the hearings
suggests LCDC supports the right of...
The Forest and Rangeland Renewable Resources Planning Act of 1974 requires the U.S. Forest Service to periodically evaluate the U.S. timber situation. An important part of such studies is the determination of forest product imports from Canada through evaluation of Canadian log and product supply conditions. Other studies have projected...
A recent surge in the development of irrigated agriculture in
the Fort Rock Basin of the Oregon High Desert has resulted in two
principal types of agricultural operations in the area: cow-calf
operators and cash-crop agriculturalists. The agroclimatic
hazards associated with the present situation and the implications
of those hazards...
The dynamics of radio frequency (RF) laminated veneer lumber (LVL) pressing are explored for the purpose of optimizing this process. The RF LVL press at the Albany Trus Joist plant is the focus of this investigation. The investigation first focuses on bond strength development characteristics of the Georgia Pacific adhesive...
