Some components of the volatiles from rye flour (Secale cereale)

Creator:: Prince, Marion
Abstract:: The volatile components of rye flour were isolated by steam distillation and trapped in cold traps under vacuum. After preliminary tests indicated the presence of carbonyl compounds, the distillate was reacted with 2,4 dinitrophenylhydrazine to convert the carbonyl compounds to their stable derivatives, 2,4 dinitrophenylhydrazones. Three classes of monocarbonyls were...

Multi-Centennial Response of ENSO Under Varying Atmospheric CO2

Creator:: Alder, Jay R.
Abstract:: The El Niño/Southern Oscillation (ENSO) affects millions of people via global teleconnections in the form of drought and torrential rainfall that impact agriculture and food production in many countries. Yet how ENSO will respond to a warming world is uncertain and a greatly debated topic. The Intergovernmental Panel on Climate...

Eastward Routing of Glacial Lake Agassiz Runoff caused the Younger Dryas Cold Event

Creator:: Leydet, David J.
Abstract:: The purpose of this thesis is to analyze an abrupt case of climate change in the past as a means to understand the mechanisms that force climate change. By looking to past analogs of climate change, we hopefully will gain an understanding of these events, which could be used to...

Hawaiian duck (Anas wyvilliana) behavior and response to wetland habitat management at Hanalei National Wildlife Refuge on Kaua'i

Creator:: Malachowski, Christopher P.
Abstract:: The endangered Hawaiian Duck (koloa maoli; Anas wyvilliana), a non-migratory and island-endemic species, experienced a significant population decline during the twentieth century due to factors such as habitat loss, overharvest, introduced mammalian predators, and hybridization with introduced feral Mallards (A. platyrhynchos). A key objective for Hawaiian Duck recovery is to...

Numerical Study of Convexity Splitting Scheme for Coupled Phase Field and Stefan Free Boundary Problems

Creator:: Bigler, Lisa A.
Abstract:: In this work, we consider a convexity splitting scheme for a coupled phase field and energy equation, a modification of Stefan problem. The Stefan problem is a free boundary value problem that models the temperature in a homogeneous multiphase medium. Each phase is modeled using a heat diffusion parabolic partial...

A multinominal approach to estimating the determinants of occupational segregation

Creator:: Knudson, Rebecca A.
Abstract:: The purpose of this study is to analyze the sources of occupational segregation between men and women. Specifically, three hypotheses are tested. First, do stiff specific training requirements for an occupation increase the likelihood that it is male-dominated, as would be expected from human capital theory? Second, do differences in...

Assessment of impacts of Canada geese on wheat production

Creator:: Louhaichi, Mounir
Abstract:: Numbers of wild Canada geese (Branta canadensis) have increased dramatically during the past 30 years in the lower Columbia and Willamette Valley systems. The damage they cause by grazing and trampling plants can be substantial. The objectives of this research were to: 1) Develop methods that provide reliable estimates of...

Transportation network connectivity, facilities encouraging walkability, and crime

Creator:: Bornasal, Floraliza B.
Abstract:: This thesis explores the relationship between crime, transportation network connectivity, and engineered facilities built to increase walkability through a case study of twenty-five sites within the city of Spokane, Washington. Using data spanning between 2008 and 2010, the author developed a GIS model representing conditions of the built environment, social...

Engineering Student Perspectives of a New Required Programming Course

Creator:: Garcia Ramirez, Jessica
Abstract:: We present student perceptions of a new first-year engineering programming class that was designed by informed research practices. While the College of Engineering at Oregon State University saw a lot of major switching in the first year, there were not many students switching into computer science (CS). This could have...

Water use of cool season grasses and their effect on grapevine (Vitis vinifera) growth and development

Creator:: Doty, Jean A.
Abstract:: The use of grass cover crops is a recommended practice in nonirrigated vineyards in the Willamette Valley, Oregon. Two studies were initiated to investigate the competitive and noncompetitive effects of grass cover crops on the growth and development of Pinot noir grapevines. Two greenhouse pot culture experiments were performed to...
