A log truck loading study in the intermountain region: production and costs

Creator:: Schneider, Ernest William
Abstract:: In order to appraise timber, it is necessary to estimate logging costs with reasonable accuracy. The purpose of this study is to provide a rethod for estimating log loading costs in the Intermountain Region. Nine different log loaders were studied loading from cold decks on six USDA. Forest Service timber...

Influence of heat exchange on foraging behavior of Zonotrichia spp.

Creator:: DeWoskin, Rob
Abstract:: The heat exchange of individuals in a foraging mixed population of Zonotrichia leucophrys and Zonotrichia atricapilla in western Oregon is analyzed with respect to the direction of stance and feeding location. Values for heat gain or loss in the field were generated from a model that estimates the equivalent black-body...

Preliminary biochemical evidence for an ascospore coat protein in Saccharomyces cerevisiae : partial characterization and timing of synthesis

Creator:: Honda, Sandra
Abstract:: Sporulation in the yeast Saccharomyces cerevisiae involves the process of meiosis which is accompanied by ascospore formation. Using intact cells or spores, preliminary biochemical evidence is given to identify ascospore wall components not found in vegetative cell walls. Cell surface components are solubilized by treatment with 8 M urea and...

Pathology, tissue residues and viral-induced mortality in mice exposed to lead and cadmium

Creator:: Exon, Jerry Hugh
Abstract:: Lead (Pb) and cadmium (Cd) are naturally occurring heavy metals which have been redistributed to a large extent by man in the environment. These metals have certain common toxic sites of action on biological systems of mammals. Simultaneous exposure to Pb and Cd is highly probable due to common sources...

Multiple-fault detection in iterative arrays

Creator:: Ramamurti, Chandramouli
Abstract:: With the advent of LSI, iterative forms of realization of digital systems are becoming increasingly popular with system designers. Many problems occurring in digital computer design render themselves suitable for iterative realization. These include adders, arithmetic logic units, coding and decoding circuits and so on. Fault-free functioning of such systems...

A study of flow acceleration over a coastal headland

Creator:: Wilkinson, David R.
Abstract:: The thesis examines the applicability of a two-dimensional flow acceleration model to describe a terrain-induced flow perturbation as measured at Yaquina Head on the central Oregon coast. The geometry of Yaquina Head together with the upstream wind values were used in estimating hilltop winds. These estimates compare well with the...

Metabolism of (1-¹⁴C) linolenic acid in coho salmon, Oncorhynchus kisutch

Creator:: Parker, Robert S.
Resource Type:: Masters Thesis

The effect of wood density on the kraft pulping properties of Douglas-fir (Pseudotsuga menziesii (Mirb.) Franco)

Creator:: Promachotikool, Montree
Abstract:: Three samples of different wood densities of Douglas-fir (Pseudotsuga menziesii (Mirb.) Franco) were cooked by the kraft process. The yields and the Kappa numbers were studied to establish the rates and the energies of activation of the pulping and delignification reactions respectively. Wood properties did not show significant effects on...

Performance of planted seedlings in shelterwoods near Prospect, Oregon

Creator:: Giles, Robert Steven
Abstract:: A survey of partial cuts planted with bare-root seedlings, was conducted on the Prospect Ranger District, Rogue River National Forest, Oregon, during the 1977 summer season. The purpose was to assess stocking and its composition under present levels of canopy cover, and to determine relationships between canopy density and performance...

Critical conditions for carriage passage at the support jack for uphill yarding

Creator:: Brantigan, Richard Thomas
Abstract:: Critical skyline and mainline tensions were identified as the conditions necessary for successful carriage passage uphill over an intermediate support jack. These critical tensions were measured during field tests and compared with predicted values from weightless line, rigid link, and catenary analyses. All three analyses predicted critical skyline tensions within...
