Weed management in sustainable farming systems often requires the integration of several different pest management techniques. Cultural, biological, and chemical pest control efforts can be utilized to contribute to the common goal of reducing weeds in vegetable row crop systems. This research addresses how common disturbances such as tillage and...
Cover crop establishment in late-season crops, like sweet corn, may be difficult due to the relatively short operational window following crop harvest. In regions like western Oregon, where fall-precipitation can occur when the crop is still in the field, cover crops may not be able to be planted, due to...
The Willamette River Basin supports 70% of Oregon’s population and contains the richest native fish fauna in the state, (Hulse, Gregory, & Baker, 2002). The Basin is facing changes that stress its water management regimes. Is the Basin’s water management regime able to adapt in the face of these changes?...
Systemic hypertension, a persistent elevation in systemic arterial blood pressure (BP), is a well-recognized disorder in cats. Failing to diagnose it accurately could lead to organ damage or unnecessary lifelong therapy. Doppler ultrasonic flow detectors are commonly used for indirect BP measurements in cats. However, whether the audible static from...
In this thesis, Elizabeth Summer Wimberly details the profile of generation 1.5 students as a group of students who can need extra support in higher education. Generation 1.5 students stand distinct from both international students and native, monolingual students. As such, placing generation 1.5 students in either a mainstream or...
Thomas Stearns Eliot’s 1922 modernist poem The Waste Land presents itself as an alternative to the decaying society Eliot found himself inhabiting. It begins as a personal means of pulling together one’s fragmented consciousness, but in doing so Eliot manages to present a solution to a world of selfishness—looking beyond...
The fundamental physics of turbulence in plasma is not well understood. Recent studies of the plasma deflagration accelerator in the High Temperature Gasdynamics Lab at Stanford University have demonstrated the presence of small scale instabilities that limit the lifetime of the jet/Z pinch and are not reproduced by coaxial plasma...
In the summer of 2007, a biophysical experiment was conducted to identify physical processes that determine the delivery of invertebrate larvae and juvenile rockfish to rocky intertidal and kelp forest communities in northern Monterey Bay, California. The experiment was sponsored by the Partnership for Interdisciplinary
Studies of Coastal Oceans (PISCO)...
The purpose of this study was to determine the concerns of past participants of the Summer Agriculture Institute regarding the use of agriculture as a context for teaching and to determine how they implement curriculum integration. The study used the Concerns-Based Adoption Model as a theoretical framework, which resulted in...
Native plants provide many ecosystem services while also having great beauty and are a valuable component of the landscape. As use of these plants in habitat restoration, agricultural insectary plantings, and home landscapes increases so does demand for information on the basic biology of a group of species that have...
