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...
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...
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...
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...
The internal structure of natural fiber composites can be manipulated by controlling the spatial distribution of fiber orientation and internal chemical and thermodynamic conditions during their consolidation. Objects highly tailored to specific service demands may thereby be produced. Techniques to form miniature structural beams from oriented hemp and random wood...
A three-dimensional model based on fundamental principles to simulate heat and
mass transfer and mat densification during hot pressing of wood-based composites is
presented. Mechanisms included in the analysis are water vapor and air transfer by gas
convection and molecular gas diffusion, conductive and convective heat transfer, and
sorptive effects,...
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...
