Fate and transport of the surfactant linear alkylbenzenesulfonate in a sewage-contaminated aquifer

Creator:: Krueger, Carolyn J.
Abstract:: Linear alkylbenzenesulfonate (LAS) is the most widely used anionic surfactant in commercial detergent formulations. The environmental fate of LAS is of interest because of its disposal to wastewater treatment facilities and subsequent occurrence as a micropollutant in surface waters and groundwater. While LAS fate in wastewater treatment systems and surface...

An evaluation of understory vegetation dynamics, ecosystem resilience and state and transition ecological theory in an eastern Oregon ponderosa pine forest

Creator:: Carr, Craig A.
Abstract:: Relatively recent increases in ponderosa pine abundance have effected unprecedented changes to ecosystem structure and function. Efforts to restore ponderosa pine systems are often focused on the manipulation of tree structure and the re-introduction of a more natural fire regime. Successful restoration should also incorporate understory components but information addressing...

Allozyme genetics and mating systems of Cuphea Laminuligera and Cuphea lutea

Creator:: Krueger, Sharon K.
Abstract:: Cuphea laminuligera Koehne and Cuphea lutea Rose in Koehne are undomesticated species having potential as oilseed crops. Genetic markers and mating systems have not been described for these species. Our objectives were to survey these species for allozyme variation, analyze the segregation and linkage of polymorphic loci, estimate autofertility and...

The response of soils, streambanks and instream coliform bacteria levels to grazing management in a riparian area

Creator:: Bohn, Carolyn C.
Abstract:: This thesis describes a case study of the effects of five systems of grazing on watershed values in a deteriorated riparian area. Soil infiltration, bulk density and penetrability, streambank edge movement and coliform bacteria were monitored for seven years along a stream in the Blue Mountains of northeastern Oregon. For...

Relationships of exotic species and wildfire to the threatened plant Silene spaldingii

Creator:: Menke, Carolyn A.
Abstract:: In the canyon grasslands of Garden Creek Ranch Preserve in Idaho, where the threatened plant Silene spaldingii occurs and invasion by the exotic species Centaurea solstitialis and Bromus tectorum is proceeding rapidly, I examined environmental and community patterns of site invasion, and evaluated the apparent influence of invasion on Silene...

Evaluation of Serratia Ureilytica as a Greener Unsealed Road Stabilization Method

Creator:: Portugal, Carla Ribeiro Machado e
Abstract:: Covering half of South America, Brazil is one of the largest agricultural and commercial forest producers globally, with a correspondingly complex road network necessary to support the production and marketing processes of such goods. Contrary to global statistics, almost 90% of the country’s road network is classified as unsealed or...

Residential water conservation and energy efficiency impacts through effective scheduling and opportunities for regional expansion : a case study of a gas tankless water heater with recirculation loop

Creator:: Johnson, Erica M.
Abstract:: This study focused on the potential water and energy savings from implementing a revised schedule of a recirculation pump connected to a condensing gas tankless water heater located in a study home in Portland, Oregon. The existing recirculation pump activation schedule was studied for its impact on the overall water...

Bridging the Gap Between Equilibrium Properties and Ultrafast Dynamics with Time-Resolved Spectroscopy of Functional Systems

Creator:: Krueger, Taylor D.
Abstract:: Ultrafast spectroscopy has recently gained momentum as a powerful, noninvasive characterization toolset capable of studying a diverse array of samples with applications in chemistry, physics, biology, engineering, and more. Two popular ultrafast spectroscopic techniques include femtosecond transient absorption (fs-TA) and femtosecond stimulated Raman spectroscopy (FSRS). The latter of these techniques...

Reconstruction and Validation of the Integrated Diagnostic SystEm for DAiry Cow WeLfare (IDEAL) to Assess Real-time Animal Well-being on Confined and Grazing Dairy Farms

Creator:: Krueger, Angela K.
Abstract:: Animal welfare is an essential component of agricultural production and animal use in teaching and research. However, defining animal welfare is intrinsically difficult because of how history and societal values and perceptions have shaped the term. Animal welfare encompasses three main ideas: physical well-being, normal affective/emotional states, and the ability...
