A study of El Niño/southern oscillation : numerical experiments and data analysis

Creator:: Ahn, Joong Bae
Abstract:: For the purpose of investigating the fundamental nature of the interannual oscillation observed in the tropical Pacific in conjunction with El Nino/Southern Oscillation (ENSO), the Comprehensive Ocean Atmosphere Data Set was analyzed. Based upon this analysis, an "intermediate" tropical atmosphere-ocean coupled model was developed. For reason of their particular importance...

An application of transfer function and econometric procedures to employment impact analysis: Grant County, Oregon

Creator:: Lin, Tsae-yun Daphne
Abstract:: This study centered upon two objectives. First, to demonstrate and apply a statistical method, the transfer function, and to test its usefulness in regional economic modeling and regional impact ana1ysis; and second, to obtain a better understanding of the causal relationships among total employment, government employment, lumber and wood products...

Reaeration in small mountain streams

Creator:: Holtje, Ralph Kenneth
Abstract:: Fishery biologists and watershed management specialists have recently begun to investigate the pollutional threat posed by organic debris left in or near the forest watercourses. Oxygen content in some streams has fallen below the limits required for fish survival. The biochemical oxygen demand exerted by the debris and the reaeration...

Effect of thinning and fertilization on wood properties and intra-ring characteristics in young Douglas-fir

Creator:: Bodner, Josef
Abstract:: The purpose of this study was to determine if thinning, fertilization or a combination of thinning and fertilization had an effect on overall average specific gravity, modulus of elasticity, modulus of rupture, fiber length and intra-ring characteristics. Material for this experiment consisted of 7 trees randomly selected from each of...

Assessing biaxial strength characteristics of wood-based structural panels

Creator:: Cheng, Ping, 1960-
Abstract:: Biaxial strength characteristics of wood-based structural panels were evaluated by using analytical and experimental methods. Cruciform plywood specimens were tested under biaxial tensile-tensile, compressive-compressive loadings in a symmetrically-jointed- arm test fixture, which was mounted on a universal testing machine. Performance of the test fixture was also evaluated during the tests....

Chemical composition studies of Oregon and Washington coastal basalts

Creator:: Hill, Dale Wayne
Abstract:: Basalts of both Eocene and Miocene age from several groups along the Oregon and Washington coasts have been analyzed for some major, minor, and trace elements using instrumental neutron activation analysis (INAA). The rare earth element (REE) patterns observed in these samples are used for comparisons within the groups studied...

Classification strategies for unbalanced binary maps : finding Ponderosa pine in the Willamette Valley

Creator:: Riddell, Audrey P.
Abstract:: Forest species classifications are becoming increasingly automated as advances are made in machine learning. The algorithms used to identify tree species range from simple decision trees to intricate neural networks, and often excel in accurately delineating tree species. However, complex algorithms can have high input costs, including the cost of...

Influences of soil acidity and variety of plant on the populations of Rhizobium trifolii found in nodules of Trifolium subterraneum L.

Creator:: Dughri, Muktar H.
Abstract:: Complementary methods of strain identification were sought to delineate the composition of the population of Rhizobium trifolii found in nodules of Trifolium subterraneum L. when exposed to an Abiqua silty clay loam (Cumulic Ultic Haploxeroll) containing a resident population of R. trifolii. Sodium dodecyl sulfate polyacrylamide gel electrophoresis (SDSPAGE) was...

A systematic and ecological study of Astragalus diaphanus (Fabaceae)

Creator:: Wright, Carolyn E.
Abstract:: Astragalus diaphanus is a rare plant endemic to the John Day River drainage of north-central Oregon. This species has several interesting features, including the dimorphism of its fruit and its geographical isolation from the two nearest taxonomically related species, which occur in Colorado. This study addressed the species' distribution and...
