In these tests, phenolic constituents from bark of Shasta red fir were found ineffective as stiffening agents for corrugating medium. Other means of application, however, may be effective.
Gum from inner bark of Shasta red fir was not so effective as a beater additive as was locust bean gum, but...
Solid-state amorphous materials show amazing promise in thin-film electronics. The interface-to-bulk ratio of thin films makes interfacial chemistries of these systems of utmost importance. Thin films of amorphous metals, dielectrics and semiconductors have novel chemistries that are not only based upon their elemental constituent makeup, but also based upon the...
Observations were made of salinity, temperature, nitrate +
nitrite, phosphate, silicate, total available nitrogen, and chlorophyll
a in nine areas of the Alaskan Inside Passage during April of 1971.
In general all properties indicated the water to be well mixed throughout
this area. The conservative properties were particularly uniform.
The...
The nature and magnitude of experimental errors due to ⁶⁵Zn
adsorption by inorganic surfaces was examined in a laboratory system
designed to measure ⁶⁵Zn uptake by marine phytoplankton. In the pH
range, 6.3±.1 to 7.5±.1, a precipitate formed in the algal nutrient
medium selected for the system. To this seawater-base...
The system in this thesis uses multiple Intel iSBC86/12A cards
connected to the Intel Multibus. The system was written using the Intel
language PLM86. The final result is a low level debug tool that
provides the user with the following capabilities: examine/change
memory, examine/change processor registers, load a user written...
The specific geography of individual wine growing regions has long been understood to be a significant factor in predicting both a region’s success in producing high quality grapes, and the resulting demand for wines produced from that region's fruit. In the American wine industry, American Viticultural Areas (AVAs) are increasingly...
The objective of this study was to determine the
feeding habits of the Mazama pocket gopher (Thomomys
mazama Merriam) in the pine region of south-central
Oregon. Damage caused by pocket gophers to conifer
regeneration was a major incentive for this research.
A permanent reference collection, consisting of
epithelial tissue from...
The Pacific Northwest has a relatively low diversity of primary freshwater fishes with most of the endemism and diversity in the Columbia River and Klamath River. However, the Oregon Coastal Subprovince defined as the coastal rivers from Miami River in the north to Sixes River in the south, has a...
Volcanism is an agent of major disturbance in many parts of the world. While the effects of volcanic disturbance are fairly well-known among some groups of species, few studies have been performed in bird communities. Likewise, few studies have attempted to compare how communities in temperate and tropical biomes respond...
