Per- and Polyfluoroalkyl Substances (PFAS) in Environmental Air-Water Matrices and Light Non-Aqueous Phase Liquids (LNAPL)

Creator:: Schwichtenberg, Trever J.
Abstract:: The presence of per- and polyfluoroalkyl substances (PFAS), organic contaminants first synthesized in the 1940s, has been reported worldwide in a variety of environmental matrices and ultimately in biological systems including humans. Ongoing research into PFAS has included identifying novel PFAS, assessing their fate and transport in the environment, and...

Per- and Polyfluoroalkyl Substances (PFAS): Protein Binding and Partitioning and Sorption in Light Non-Aqueous Phase Liquids

Creator:: Christie, Emerson C.
Abstract:: Per- and polyfluoroalkyl substances (PFAS) are anthropogenic surfactants that have recently been identified as persistent organic pollutants. These so called “Forever Chemicals” have been detected in drinking waters, ground waters, soils, and consumer and industrial products globally; with environmental impacts stretching into the artic, far from known PFAS sources. The...

Elevated temperature and the production of juvenile Chinook salmon (Oncorhynchus tshawytscha) in a model stream

Creator:: Bisson, Peter Andre
Abstract:: Temperature was elevated approximately 4° C in a model stream relative to an unheated, but otherwise similar control stream. The streams were located outdoors, received identical amounts of exchange water from a nearby creek, and followed natural diurnal and seasonal temperature cycles Juvenile spring chinook salmon (Oncorhynchus tshawytscha) were introduced...

An Analysis of Post-Medieval Ceramics from the Pendle Hill Witches Archaeological Excavation

Creator:: Connolly, Madeleine E.
Abstract:: This analysis seeks to (1) establish a typology of the post-medieval ceramics from the Malkin Tower site, (2) determine vessel forms and extrapolate site function, and (3) establish a tentative chronology for the site. Over four hundred post-medieval ceramic artifacts from the Malkin Tower site were analysed via descriptive and...

Implementation and evaluation of a participating media radiation model in the TEMPEST thermal-hydraulic computer code

Creator:: Rector, David R.
Abstract:: In this work, a method for solving the differential form of the radiative transfer equation was implemented into an existing three-dimensional thermal-hydraulic computer program known as TEMPEST. The method used was the P-l approximation, where the angular distribution of the radiation intensity is represented by a truncated series of spherical...

A model for understanding the influence of selective and nonselective harvest on fish populations

Creator:: Hirai, Takayuki
Abstract:: To understand the influence of selective harvesting on the adaptive capacity of fish populations in changing environments, a computer simulation model was developed. In the model, hypothetical populations were composed of five different life histories, which were genetically determined. Each life history type had its own rate of survival and...

An analysis of production and consumption of food in Korea

Creator:: Im, Kwang H.
Abstract:: The general objective of this study is to analyze the production and the consumption of food in Korea for the years 1955 through 1969 and to project them for the years 1970 through 1980. This study has the following purposes; (1) To examine the trend in food production and yield....

Stream habitat utilization and behavior of sympatric and allopatric wild cutthroat trout (Salmo clarki) and hatchery coho salmon (Oncorhynchus kitsutch)

Creator:: Jacobs, Steven Edward
Abstract:: The behavior and stream habitat utilization of juvenile hatchery-reared coho salmon (Ovicozihynchus kisutch) and wild cutthroat trout (Salmo clarki) were examined to assess the nature of interactions between the species potentially resulting from introductions of hatchery coho salmon in streams. Habitat utilization was monitored in Mill Creek, Polk Co., Oregon...

Response of guyed offshore towers to stochastic loads in the presence of steady current

Creator:: Brynjolfsson, Sigurdur
Abstract:: The validity of the widely used stochastic linearization method for analysing the response of guyed towers to stochastic loads is investigated. The governing equations of a guyed tower have two main sources of nonlinearities, fluid-structure interaction and the restoring force of the cables. In this study, two models are considered....
