Velocity measurements from drifter GPS records are used in an ensemble-based data assimilation technique to
extract the river bathymetry. The method is tested on a deep meandering reach and a shallow braided reach of the
Kootenai River in Idaho....

Alien grass invasions in arid and semi-arid ecosystems
are resulting in grass–fire cycles and ecosystem-level transformations that severely diminish
ecosystem services. Our capacity to address the
rapid and complex changes occurring in these...

While radiocarbon (¹⁴C) abundances in standing
stocks of soil carbon have been used to evaluate rates of
soil carbon turnover on timescales of several years to centuries,
soil-respired ¹⁴CO₂ measurements are an important
tool for identifying more...

A major challenge for biodiversity conservation is to mitigate the effects of future
environmental change, such as land use, in important areas for biodiversity conservation. In the United
States, recent conservation efforts by The Nature...

The use of clonal varieties in forestry offers great potential to improve growth traits (quantity) and wood properties
(quality) of loblolly pine (Pinus taeda L.). Loblolly pine trees established via somatic embryogenesis (clones), full-sib...

The literature on religiousness, spirituality (R/S), and health has increased dramatically in
the past decade, but suffers from a lack of integrative theoretical models and well-defined
constructs. Drawing on self-regulation theory, we...

A combination of genetical and biochemical methods were
utilized in investigating house fly resistance to naphthalene. The
inheritance of resistance was determined by crossing a naphthalene
resistant strain of Musca domestica L. with a susceptible...

An experiment was conducted during the period November 1967
to November 1968 at Oregon State University (OSU) and the Umatilla
Branch Experiment Station (BES) at Hermiston, two trials at each
location, to answer several questions: (1) could...

A study of the relative rates of the alkyl hydrogen abstraction
from a series of meta and para substituted t-butylbenzenes by the
chlorine atom at 70°C has been carried out. Application of the
Hammett equation yielded a ρ value of -0.44 for the...

In this thesis a system analysis compares power development
plans for the 1980 decade in the Mekong countries i.e. Laos, Thailand
Cambodia, and South Vietnam. Given the decision to invest in power
development, an economic evaluation is made of...

A method of culturing Eriosoma pyricola on detached root pieces
was developed to ensure a regular supply of aphids for experimental
work. Another method was designed for studying the alate sexuparae
formation in woolly pear aphid, whereby growing...

With the advent of tradable permit programs for bad outputs (e.g., SO₂ emissions); concerns arose over whether
the theoretical gains from trade would be realized. We will employ a methodology that calculates the potential
gains accruing to...

The base Al-Zn superplastic alloy was investigated at 250°C to
determine the effect of small amounts of magnesium on mechanical
properties. Six alloys of nominal composition 0.00, 0.10, 0.25,
0.50, 0.75, and 1.00 weight percent magnesium, constant...
