The Terrors Of Everyday Life: The Gothic Novel As A Woman's Conduct Guide To Survival, 1791-1817, Jessica Berg
The Terrors Of Everyday Life: The Gothic Novel As A Woman's Conduct Guide To Survival, 1791-1817, Jessica Berg
Electronic Theses and Dissertations
The Gothic is often associated with the fantastical, with people and events that only take place within our darkest nightmares. In my thesis, I explore how, in the hands of Ann Radcliffe and Jane Austen, the Gothic exposes the hidden dangers of reality perpetuated by conduct literature. Within conduct manuals, thousands of regulations direct women’s behaviors and identify the perfect woman as one who exists passively within the safety of the domestic sphere. Radcliffe’s The Romance of the Forest (1791) and Austen’s Northanger Abbey (1817) engage in subterfuge against eighteenth-century conduct literature and expose the realities of the domestic sphere: …

Genome-Wide Association Mapping And Genomic Prediction For Enhancing Fhb Resistance In Hard Winter Wheat, Jinfeng Zhang
Electronic Theses and Dissertations
Wheat is one of the most important staple crops providing 20% of energy for 35% of the world population. Fusarium head blight (FHB), primarily caused by the fugal Fusarium graminearum Schwabe, is a damaging disease in wheat that affects global wheat production every year and causes food safety issues. The disease not only reduces the grain yield and quality but also produces mycotoxin in the diseased kernels making them unsuitable for human consumption or as livestock feeds. Breeding FHB resistant cultivar is the most effective and economical approach to managing the disease. This study combines genome-wide association study (GWAS) and …
Exploring Bioprocessing Technologies For Diverse Industrial Application Of Canola, Ahmad Fawzi N Alhomodi
Exploring Bioprocessing Technologies For Diverse Industrial Application Of Canola, Ahmad Fawzi N Alhomodi
Electronic Theses and Dissertations
Globally, canola is the second largest oilseed crop after soybean, which is processed for the commercial production of high value oil. The industrial processing steps for canola oil extraction include preprocessing (cleaning, pressing, flaking, and cooking), mechanical pressing, and/or organic solvents. This process results in large quantities of protein-rich (~ 40% dry basis) meal as a co-product. The meal is used partially in animal diet (<30% inclusion) due to high levels of antinutritional factors (ANFs) such as high fibers, phytic acid, and glucosinolates, and low metabolizable energy. Thus, this research was designed to examine various bioprocessing technologies (i.e., traditional sprouting, solid state fermentation, submerged state fermentation, co-culture fermentation, mild pretreatments, and their combinations) for possible advancement in canola use. Canola seed sprouting for 6-day period led to an increase in protein content and a reduction in ANFs and oil content of sprouts compared to ungerminated seed. Subsequent submerged state fermentation of 6- day old sprouts using three different strains (Aureobasidium pullulans, Trichoderma reesei and Neurospora crassa) further increased protein content and lowered ANFs. Solid-state fermentation of 144 h old sprouts using A. pullulans, N. crassa and T. reesei enhanced the protein content and reduced ANFs of sprouts. Sprouting canola seed for three days helped in hull removal, leading to high protein meal accompanied by low fiber and phytic acid level. Three-day seed sprouting had no effect on oil yield, but free fatty acid content was higher compared to seed oil. Co-culture fermentation of HECM under solid state process showed maximum reduction in fiber content with co-culture of A. pullulans and N. crassa while a combination of A. pullulans and T. reesei promoted the highest GLS and phytic acid reductions compared to other combinations, which indicated the advantage of coculture inoculation over monoculture in terms of ANFs reduction. Mild pretreatment of HECM using deionized water resulted in washed HECM (WHECM) with lower soluble sugars and GLS compared to untreated HECM, whereas protein and amino acid were concentrated due to the removal of soluble components. WHECM compared to HECM showed higher protein digestibility when fed to rainbow trout. Subsequent mono- and coculture fermentation of HECM and WHECM under submerged process resulted in higher protein and amino acid content and lower ANFs levels compared to uninoculated controls. The results of cellulase, endoglucanase and β-glucosidase activity indicated the crucial role of used substrates, fungi, fermentation modes (solid state/submerged stated) and inoculation methods (mono-/co-culture) on enzyme activities.

Fire Emissions In The Tropical Indonesia: Improved Estimation And Driving Forces Investigation, Xiaoman Lu
Electronic Theses and Dissertations
Indonesia has experienced frequent fires since the 1970s due to large-scale peatland conversion and extensive drainage for agricultural development. Fire emissions released from these fires have led to Indonesia being the world’s 3rd largest emitter of greenhouse gases in certain years. Given that fire emissions severely affect climate, weather, and the human environment, numerous approaches have been developed to estimate fire emissions. However, existing emission estimates differ largely by a factor of four in this tropical country because of frequent cloud interferences and low-temperature smoldering fires. Therefore, this dissertation aims to improve the quantification of Indonesian fire emissions through enhanced …

Deforming The Knight: Gawain's Descent Into Monstrosity In Sir Gawain And The Green Knight, Hannah Held
Deforming The Knight: Gawain's Descent Into Monstrosity In Sir Gawain And The Green Knight, Hannah Held
Electronic Theses and Dissertations
Sir Gawain has always been marked as a victim in the well-known poem Sir Gawain and the Green Knight, but he is much more than that. Standing with the knights of the Round Table, he seems to be the perfect example of what chivalry should look like, especially with an adherence to the common religious beliefs. However, when put into the context of the manuscript in which it was found, Gawain seems to stand as an allegorical figure of the do-not’s of feudal and religious chivalry. Using the lens of Monster Theory via Jeffrey Jerome Cohen and David Williams, I …

Defining Amino Acid Requirements Of Pregnant Sows: Challenges And Opportunities, Christian D. Ramirez-Camba
Defining Amino Acid Requirements Of Pregnant Sows: Challenges And Opportunities, Christian D. Ramirez-Camba
Electronic Theses and Dissertations
The efficient use of protein in animal production is dependent on the protein supply and its constituent amino acids (AA) in relation to the animal's needs. Excess AA are deaminated, and the resulting nitrogen (N) is excreted, whereas suboptimal AA intake reduces animal performance. Both increased nutrient excretion and decreased animal performance reduce the overall efficiency of the production unit. In sows, AA requirements should be adequate for optimizing reproductive performance, as measured, for example, by the number of pigs produced per sow per year while limiting N excretion. There is a desire to feed pregnant sows AA levels that …

Ceo Types And Firm Efficiency, Lok Chi Lam
Electronic Theses and Dissertations
This paper investigates the connection between CEO types and firm efficiency. I utilize the general ability index (GAI) as a proxy to examine and separate CEO types: generalist CEOs and specialist CEOs. Initially, I applied the pooled ordinary least square (OLS) and fixed effect regression on 26,830 firm-year observations to explore the GAI effect on firm efficiency. The finding shows that GAI has a negative impact on firm efficiency. It indicates that CEOs with lower GAI are better at improving firm efficiency; for instance, specialist CEOs are preferable to generalist CEOs. Further analysis of CEO types using the quadrant method …

Phosphorus Use And Management Based On Fertilizer Placement, Rate Of Application, And Soil Biota In No-Till Situations, Brennan Alexander Bingham Lewis
Phosphorus Use And Management Based On Fertilizer Placement, Rate Of Application, And Soil Biota In No-Till Situations, Brennan Alexander Bingham Lewis
Electronic Theses and Dissertations
Phosphorus (P) pollution has become a concern among multiple scientific organizations as it leads to eutrophication, an algal bloom that depletes lacustrine and marine ecosystems of native species. Multiple strategies can be implemented to reduce phosphorus loss from agriculture fields, which is often implicated as a cause of eutrophication. Soil phosphorus chemistry results in phosphate fertilizers absorbing to clay minerals over time. Soil phosphorus is lost from agricultural fields primarily through wind and water erosion. No-till practices prevent soil erosion, which reduces the phosphorus from loading into waterways. Fertilizer placement affects phosphorus loss. Surface application of phosphorus fertilizers increases the …
Characterizing The Lir Domain Of Abin1 And Identifying Its Role As A Regulator Of Mitophagy, Andrew Rhiner
Characterizing The Lir Domain Of Abin1 And Identifying Its Role As A Regulator Of Mitophagy, Andrew Rhiner
Electronic Theses and Dissertations
A20 Inhibitor of NF-κB (ABIN1/TNIP1) is a known regulator of TNFα signaling induced cell death and inflammation. The regulatory activity has been attributed to ABIN1’s recruitment of the ubiquitin editing enzyme TNF-α-induced protein 3 (TNFAIP3/A20) to Receptor-interacting serine/threonine-protein kinase 1 (RIPK1). The regulation of RIPK1 by ABIN1 and A20 relies on a third player, linear ubiquitin chain assembly complex (LUBAC), which is involved in the recruitment of ABIN1 to RIPK1. Loss of LUBAC or ABIN1 is embryonic lethal, but loss of A20 is not embryonic lethal. The embryonic lethality due to loss of ABIN1, paired with the lack of lethality …

Living In A Gradient: The Influence Of Water Temperature Variation On Development, Settling Time And Survival Of Pallid Sturgeon Larvae In The Missouri River, Maria Elizabeth Erceg
Electronic Theses and Dissertations
Pallid Sturgeon (Scaphirhynchus albus) are a federally endangered species experiencing widespread reproduction and recruitment failures. Recruitment failure is hypothesized to be caused by habitat modifications made to the Missouri River that disrupt connectivity and alter temperature profiles downstream of constructed dams. Hypolimnetic releases from Missouri River dams affect the temperature downstream, creating colder conditions during the downstream drifting phase for dispersing larvae. Understanding the influence of water temperature changes on larval development is crucial for recovery efforts. In this study, we evaluated the effects of water temperature daily heating rate on energy use, settling behavior, and growth rate of endogenously …
