The Rebirth of Direct Farm Marketing and the Rethinking of Food Safety Regulation: A View from the Ground in Oregon

O Criador:: Brekken, Christy Anderson
Abstract:: Consumers are increasingly turning to farm direct foods for personal reasons, such as fresh and healthy food, and for public reasons, such as supporting local and rural economies and reducing the environmental impact of their food choices. As a result, farmers’ markets and other direct farm marketing has increased substantially...

Modeling and Validation of Denitrification Bioreactors for Agricultural Tile Drainage

O Criador:: Morkoc, Adnan
Abstract:: Agricultural tile drainage is one of the major causes of increasing nitrate (NO3-) concentrations in surface water bodies thanks to the usage of nitrogen fertilizers and manure. Denitrifying bioreactors are constructed at the edge of agricultural lands in order to remove NO3- from drainage water through labile carbon substrates intended...

Modelling of an Array of Floating Oscillating Water Column Wave Energy Converters with Full Hydrodynamic Coupling and Nonlinear Power Take Off Dynamics

O Criador:: Gaebele, Daniel T.
Abstract:: Wave energy is one of the most promising renewable energy sources. Thus, research in this field has increased substantially over the last decade. However, significant costs associated with development and maintenance have so far impeded the implementation of commercially viable projects. Furthermore, the hydrodynamic interactions between water and prototypes meant...

Identification of Viruses Associated with Raspberry Leaf Curl Disease

O Criador:: Guzman Martinez, Melinda
Abstract:: Raspberries are an important commodity worldwide, with the United States (U.S.) leading fourth in global production in 2017. An important factor when shipping propagated Rubus across the globe is the security of clean plant material verified through pathogen detection methods which is vital in preventing disease spread. A raspberry virus...

The Geology, Geochronology, and Geochemistry of the Miocene Volcanic Rocks at the Inmaculada Ag-Au Mine, Southern Peru

O Criador:: Cuellar Quispe, Juan Carlos
Abstract:: The Inmaculada Mine is located in the Miocene belt of epithermal deposits that extends from southern Peru to northern Chile and Bolivia. This belt is known for its silver-rich epithermal veins that have been worked since colonial times. The Inmaculada Mine belongs to a mining district that includes, from north...

Development of an anammox HDH enzyme assay to characterize heavy metal inhibition with protection tests

O Criador:: Qiao, Guancheng
Abstract:: Removing nitrogen from wastewater is critical to avoid eutrophication of receiving waters. Due to its potential economic benefits, the use of anammox bacteria to remove nitrogen from wastewater is gaining in popularity. Anammox bacteria utilize NO₂- to oxidize NH₄+ to N₂. However, anammox bacteria are sensitive to a wide variety...

Daily Stressors and Stressor-Related Affect: The Role of Stressor Type, Who was Involved, and Resolution Status

O Criador:: Witzel, Dakota D.
Abstract:: Daily social stressors are important everyday experiences that influence an individual’s daily health and well-being across the lifespan. One pathway through which daily social stressors influence health and well-being is through changes in positive and negative affect. The vast majority of previous research has focused on individual difference characteristics to...

Power Network Parameter Correction via Sparse Unsupervised Regression

O Criador:: Senaratne, Galpottage Dilan S.
Abstract:: Accurate information of power network parameters is essential for performing various power system monitoring and control tasks including state estimation, economic dispatch, and contingency analysis. In this paper, we present a novel approach of power network parameter correction wherein we exploit the sparse nature of parameter errors. Parameter error correction...
Resource Type:: Masters Thesis

The Role of International Donors In Water Diplomacy. Case Study of the Aral Sea Basin

O Criador:: Ismoilov, Botir
Abstract:: International donors play a significant role in the mitigation and prevention of transboundary water disputes and the promotion of cooperation. In doing so, donors can exercise water diplomacy through a wide range of instruments from facilitating or mediating the negotiations to financing capacity building and specific activities in official and...

An Ecological Assessment of a Potential Sea Otter (Enhydra lutris) Reintroduction to the Oregon Coast

O Criador:: Kone, Dominique
Abstract:: Sea otters (Enhydra lutris) used to exist along coastlines throughout much of the North Pacific Ocean. During the Maritime Fur Trade, sea otters were extirpated from much of their historic range, including Oregon. There is renewed interest in reintroducing sea otters to Oregon. Managers seek improved understanding of the potential...
