Proanthocyanidins (PACs) containing A-type linkages, like those found in cranberry, have been implicated as beneficial phenolic compounds in human health, but much research is still required to better understand their activity fully. One major impediment to progress has been the existence of effective analytical methods for A-type PAC quantification. This...
Proanthocyanidins are a grape-derived phenolic class of compound that provide wine with bitterness and astringency. Because of this, proanthocyanidins are considered to be essential components of wine quality. Proanthocyanidins are localized in the seed, skin and stem tissue of the grape berry and the composition of proanthocyanidins will vary depending...
Representing the most common flavonoid consumed in the American diet, the flavanols and their polymeric condensation products, the proanthocyanidins, are regarded as functional ingredients in various beverages, whole and processed foods, herbal remedies and supplements. Their presence in food affects food quality parameters including astringency, bitterness, sourness, sweetness, salivary viscosity,...
Many climatic factors influence grape berry composition including nutrient status, water availability, biotic stress, sun exposure and temperature. Previous research examined the effects of many factors listed above and much progress has been made. It is often difficult, however, to separate effects that typically confound each other, such as sun...
Color stability and mouth feel quality are two of the most important aspects of red wine quality. Anthocyanins and proanthocyanidins are responsible for these attributes and it has been shown that weather conditions during the growing season and grape maturity can effect these components in wine. However, investigations into proanthocyanidin...
Red wine texture is a particularly important property of overall red wine quality
whose origin is not well understood. The overall goal of this study was to improve our
understanding of how chemical composition influences red wine texture. Unlike
previous studies that have used model systems to investigate how chemical...
Two experiments were conducted to evaluate the use of wet brewers' grain (WBG) alone and with straw so it can be used as part of the sole ration for ruminants. In Exp. 1, WBG was ensued alone and was mixed with one of two straws, wheat or tall fescue grass...
This thesis examines notions of social unintelligibility produced within queer spaces in two primary texts: Justin Torres' We the Animals and Mario Bellatín's Beauty Salon. Chapter One discusses the racial and queer marginalization of the unnamed narrator and explores his turn towards an "animal language" in his moment of exposure...
Logging and forest thinning operations generate large amounts of residues in the form of small trees, branches and foliage that are usually left on the ground to decay or are burned. These resources are readily available, but it is uneconomical to remove them from the forest. The potential utilization of...
Energy development is expanding rapidly across the western US. Negative effects have been documented for some wildlife, but consequences of development are unclear for other taxa, including raptors. We had the opportunity to examine effects of oil and natural gas development on two raptor species of conservation concern, ferruginous hawks...
Sawmills are very complex systems that involve many manufacturing processes. The variability of their raw material adds further to this complexity as each log has characteristics that determine its processing path. Therefore, computer simulation is a very useful technique for analyzing sawmill performance. This thesis describes a simulation computer model...
Developing accurate predictive distribution models requires adequately representing relevant spatial and temporal scales, as these scales are ultimately reflective of the relationships between distributions and influential environmental conditions. In this research, we considered both spatial and temporal scale and the influence each has on predicting broad-scale distributions of two disparate...
A sawmill is similar to other manufacturing enterprises when it comes to making decisions, scheduling production and meeting customer demands. In order to help sawmills achieve their goals, and because there is such a high degree of variability in the raw material used in this industry, computer simulation has proven...
This thesis offers a theory of queer materiality as a way of understanding the interconnectedness of freaks, ghosts, and madness in Victorian culture, and how these elements coalesce in Victorian literature to destabilize the knowable materiality of normative social structures and forms of embodiment, leading to the production of queer...
The purpose of this study was to investigate the household tasks that
school-age children perform and the average amount of time spent performing
those tasks. The sample included 219 children in 135 families
taken from the Oregon sample of 210 families interviewed for the Northeast
Regional Research Project 113: "An...
In A Portrait of the Artist as a Young Man, James Joyce used
the form or structure of his language to connote a meaning which
supported the content of the text. The elements of form he used
most often were sentence and paragraph structure, punctuation,
rhythm, and classical rhetorical schemes....
Large, alluvial rivers are naturally diverse, both in structural complexity and as drivers of landscape dynamics. Floodplains provide a mosaic of habitat types for aquatic, semi-aquatic, and terrestrial organisms and act as the framework for vital chemical processes to occur. In large part, this variety is due to the ability...
On September 12th 1960, just two months prior to one of the closest
Presidential elections in American history, John F. Kennedy faced the Houston
Ministerial Association and delivered a powerful speech on religion and
Americanism. The "religious issue" of the 1960 campaign drew immense interest
and trumped other issues pertinent...
In his works, A Portrait of the Artist as a Young Man (1916) and Ulysses
(1922), James Joyce demonstrates what he perceives to be the paralyzing effects of
those institutionalized religions that sit at the center of cultures. Drawing on Michel
Foucault's analysis of institutional dressage as well as his...
