Early spring nutrient conditions of southeastern Alaska's Inside Passage

Creator:: Coughenower, D. Douglas
Abstract:: 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...

Non-biological uptake of zinc-65 from a marine algal nutrient medium

Creator:: Tomlinson, Richard Douglas
Abstract:: 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...

A multi-microprocessor debug executive

Creator:: Edmonds, Douglas E.
Abstract:: 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...

How well do American viticultural areas correspond with the soil classes in Oregon's northern Willamette Valley? A question for the wine industry

Creator:: Wood, Douglas T.
Abstract:: 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 feeding habits of the Mazama pocket gopher in the pine region of South-Central Oregon

Creator:: Burton, Douglas Harlow
Abstract:: 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...

A study of several anatomical variables in relation to their effect on tensile strength of Douglas-fir

Creator:: McMinimy, Lawrence Otto
Abstract:: A microscopic study was conducted on specific gravity wafers taken from standard tensile strength specimens of young growth Douglas-fir. Samples were studied to determine the effect of variables such as percent summerwood, fiber length and fibril angle on tensile strength of Douglas-fir. The sample specimens were picked so effects of...

Thinning effects on stand and tree growth : different perspectives on same old questions

Creator:: Romero Castaño, Pablo
Abstract:: The search for the stand density that optimizes growth and hence generates the maximum amount of wood is one of the philosopher’s stone in modern forestry. Since scientific methods were applied to forestry, numerous generations of foresters have studied the relations between stocking density and growth, obtaining diverse results and...

Taxonomy and systematic relationships of tui chubs (Siphateles: Cyprinidae) from Oregon's Great Basin

Creator:: Remple, Stacy L.
Abstract:: There are three recognized species of Siphateles from the Great Basin; S. alvordensis, S. boraxobius and the tui chub, S. bicolor. One species, S. boraxobius, is endangered and one population of tui chub at Hutton Spring is threatened. Despite several morphological and molecular studies, the taxonomy and relationships of tui...
