Summarizes information on wood as an engineering material.
Presents properties of wood and wood-based products
of particular concern to the architect and engineer. Includes
discussion of designing with wood and wood-based products
along with some pertinent uses.
Protein microcapsules (PM) were developed as a tool for investigating aspects of dietary protein utilization by mussels, Mytilus edulis trossulus. Digestion of PM in vitro by protease, trypsin, amylase and extracts from the gut of mussels varied significantly depending on the type of protein encapsulated or whether carbohydrates were added...
Urban areas currently cover a small fraction of Oregon’s landscape but will expand to accommodate an increasingly large proportion of the state’s growing population and economic activity. Residential developments on rural lands now cover more than twice the area occupied by Oregon’s urban developments and are growing rapidly. Oregon urban...
The use of Native American fire regimes evolved in the Klamath-Siskiyou bioregion over millennia. A mixture of Native American and Euro-American socio-cultural management has developed from adaptations to climate, topography, ecological processes, and land use practices. This research incorporates Traditional Ecological Knowledge (TEK) to partially examine the role of tribal...
Short-term changes in the distribution, surface to 10 meters, of
phytoplankton-associated trace metals (Fe, Mn, Cr, Zn, Co, Ni, and
Cu) were studied in the near-shore waters off Humboldt Bay,
California, through the summer of 1971. The depth distribution of
phytoplankton-associated trace metals was related to local hydrography.
During periods...
A parasitic wasp, Trioxys pallidus Haliday
(Hymenoptera: Aphidiidae) was imported from Europe and
initially released against the filbert aphid Mvzocallis
coryli (Goetze) in hazelnut (filbert) orchards of the
Willamette Valley, Oregon beginning in 1984. In the
present study, I investigated the establishment rates of
this parasitoid. A total of 13...
The variation in fatty acid composition between the "bound" and
"free" lipid in stored anchovy meal was determined using gas-liquid
chromatographic analysis. A model system of fresh anchovy oil on
powdered lactalbumin was also studied to determine the changes in
extractability and fatty acid composition which occur during oxidation.
All...
The shoe repair transaction, as it occurs in the 5000 or so remaining shoe repair shops in the United States, is currently unexamined in academic literature for the significance it holds for either shoe repairers or their customers. Making use of both quantitative and qualitative methods of data collection, this...
The inherent and apparent optical properties of different ocean regimes are the basis for all optical remote sensing of the ocean. Ecological information derived from remote sensors therefore relies on having a detailed understanding of how particulate backscattering and absorption contribute to the bulk optical signal. The absorption
characteristics of...
