This dissertation has two objectives. The first objective is to determine where best to situate the study of mentoring (i.e. the 'making of scientists') on the landscape of the history of science and science studies. This task is accomplished by establishing mentoring studies as a link between the robust body...
John Archibald Wheeler (09 July 1911- ) is a familiar name to physicists and historians of physics alike. Among his many contributions to the corpus of knowledge, in 1939 John Wheeler and Niels Bohr co-authored the first paper on the generalized mechanism of nuclear fission. Beyond that seminal work, Wheeler...
Drought events have been shown to impact species distributions and are predicted to increase in frequency as the climate changes. As this occurs, ecologists predict species distributions will shift dependent upon species ability to track climate. These shifts in species distribution are expected to be particularly acute in arid and...
Drought is expected to increase in many parts of the world and has been shown to affect tree physiology and growth, with seedlings being particularly vulnerable. Seedling drought responses are often species dependent, and even within species different populations may demonstrate a spectrum of responses to drought, from susceptibility to...

Bruno Latour’s Facing Gaia provokes us to embrace our Earthboundedness to approach the problematic political ecologies of the Anthropocene. Latour’s call for the Earthbound is to re-trace networks of society, institutions, and meaning and to challenge, as enemy, those that would continue to behave as if we lived on more...
Later maturing cultivars and increased ability to apply irrigation have led to inquiries by producers about proper irrigation management in tall fescue (Festuca arundinacea Schreb.) seed crops. The literature reveals little information about irrigation of perennial grass seed crops in general, and none about tall fescue in particular. Willamette Valley...
This thesis describes 1) development of a gastric retention device (GRD) to
increase gastric retention time of certain drugs, 2) product formulations of an immediate
release itraconazole and controlled-release ketoprofen. GRD was fabricated from crosslinked
carbohydrate polymers. Rate and extent of hydration of the film in water and in
simulated...
Roots of greenhouse-grown peppermint (Mentha piperita L.) and spearmint (Mentha spicata L.)
plants and in vitro-grown shoot cultures were inoculated with Verticillium dahliae conidial suspensions to
study symptom development, detection, and elimination of the V. dahliae. There were significant
differences in the symptom expression of control and infected shoot cultures...
