Runoff Water Quality And Crop Growth As Affected By Wastewater-Derived Struvite, Machaela Morrison

Graduate Theses and Dissertations

Mined phosphate rock, used to produce phosphorus (P) fertilizers, is a finite resource. Struvite (MgNH4PO4 • 6H2O) that has been synthetically produced from a stock solution of known P and nitrogen (N) concentrations has been shown to be an effective, alternative fertilizer-P source for various crops. However, little is known about the runoff-water-quality implications from and the crop response to soil application of struvite created from an actual municipal wastewater source. This study consisted of two objectives: i) to evaluate the effects of soil [i.e., Creldon (Oxyaquic Fragiudalf), Dapue (Fluventic Hapludoll), Roxana (Typic Udifluvent), and Calloway (Aquic Fraglossudalf) series], fertilizer-P …

Modeling The Egyptian Goose (Alopochen Aegyptiaca) Invasion; And Future Concerns, Percival Matzinger Marshall

Graduate Theses and Dissertations

In an increasingly interconnected world, the ecological and financial cost of invasive species is expected to continue to climb through the movement of exotic biota. Understanding the driving forces behind how a species invades, what environments promote their establishment, and what impacts they are likely to have on the invaded environment are all critical for management. Waterfowl, order Anseriformes, are one such category of invasive species of concern due to their popularity of accidental introduction, ease of movement, and propensity to affect both terrestrial and aquatic ecosystems. The Egyptian Goose (Alopochen aegyptiaca) is a native to the African continent that …

Securing Rice Safety Through Innovative Radiative Heat Treatment And Proper Storage, Faith Achieng Ouma

Graduate Theses and Dissertations

Securing the microbial safety of rice is a rising priority within the food industry, especially when used as an ingredient to manufacture ready-to-eat, minimally-processed products. Mold contamination is typically the most problematic for rice because certain species of Aspergillus produce toxic secondary metabolites known as aflatoxins, rendering the grain unfit for human and animal consumption. The objectives of this study are to: (1) investigate the effectiveness of using high-power (915 MHz frequency), short-duration microwaves (MWs) to inactivate microbes on rough rice; (2) use a three-level screening design to determine which storage factors, such as temperature, relative humidity (RH), storage duration, …

On Neo-Humean Accounts For Natural Laws, Tori Helen Cotton

Graduate Theses and Dissertations

Humeanism about laws is a metaphysical doctrine that claims that the complete scope of the world is comprised of the mosaic—a vast collection of particular, localized facts about the world, and everything else supervenes on this arrangement of facts. Reductionism about laws, the claim that laws of nature reduce to, and thereby supervene on, the Humean mosaic, follows from this view. The first part of the thesis explores Humeanism about laws and the evolving landscape of pragmatic approaches within this domain. Building upon the insights gained from this analysis, the second part of the thesis proposes a novel response to …

Phenotypic And Transcriptomic Characterization Of Rice Snrk1 Mutants Developed By Crispr/Cas9 Mutagenesis, Maria Clara Faria Chaves

Graduate Theses and Dissertations

SnRK1 is a heterotrimeric protein kinase that is composed of a catalytic subunit (α) and two regulatory subunits (β and βγ), and it has a main role in regulating energy homeostasis in the plant by modulating anabolic and catabolic process. SnRK1 phosphorylates and alters the activities of enzymes involved in metabolism and regulates gene expression by altering the activity of chromatin-remodeling enzymes or the transcription factors. Rice contains three functional paralogs of SnRK1α: SnRK1αa (LOC_Os03g17980), SnRK1αb (LOC_Os08g37800), and SnRK1αc (LOC_Os05g45420). This study focused on the function of these SnRK1 paralogs by evaluating the phenotypic and transcriptomic characteristics and the disease …

Generating Health-Promoting Bioactive Compounds And Nanoporous Materials From Rice Processing Byproducts Via Supercritical Carbon Dioxide Technology, Sumanjot Kaur

Graduate Theses and Dissertations

Rice husk and bran, byproducts of rice processing, are generated in large quantities (~30-40% of the total rice weight) and are discarded as waste or burned in an open field, creating a major disposal problem for the rice industry. However, these byproducts contain high-value compounds, including phytochemicals, fiber, and proteins. Therefore, the goal of this study was to generate high-value food ingredients from rice processing byproducts using a green, innovative approach based on supercritical carbon dioxide (SC-CO2) technology. Specific objectives were to (i) extract health-promoting phytochemicals from rice husk and (ii) convert rice bran into nanoporous materials using SC-CO2. First, …

A Comparison Of Pm-Nato3’S Influence On Neural Progenitors And Mature Dopamine Neurons, Mary E. West

Masters Theses

This thesis presents significant findings regarding the role of PM-Nato3 in its interaction with developing neurons in the context of Parkinson's disease (PD) and regenerative medicine. We investigated the effects of PM-Nato3 on dopamine (DA) neurogenesis under different culture conditions, both in vitro and in vivo. In the standard dopaminergic culture condition, PM-Nato3 potentially increased the speed of DA neuron production but did not significantly increase the yield of DA neurons. In a minimal culture condition, there was no notable difference between the control and PM-Nato3 conditions, suggesting minimal impact on DA neurogenesis. In vivo studies using a mouse model …

Sexual Trauma, Health, And The Moderating Effect Of Psychological Flexibility And Inflexibility, Gabrielle A. Caselman

Electronic Theses and Dissertations

Sexual trauma is linked to adverse health outcomes (e.g., D’Andre et al., 2011). Given the negative sequelae of sexual trauma, exploration of factors that influence the relation between sexual trauma and health outcomes is crucial. Current literature suggests that psychological flexibility and inflexibility may be factors in promotion of individuals’ health or pathology (e.g., Gloster et al., 2017). The current study sought to explore the variability in psychological flexibility and inflexibility among participants and the potential moderating effects of psychological flexibility and inflexibility on the relation between sexual trauma and both mental and physical health outcomes.

Moderation analyses failed to …

Examining The Measurement Invariance Of The Revised Sociosexual Orientation Inventory Among Hispanic And Non-Hispanic White College Women, Christina Nicole Gillezeau

Psychology ETDs

I examined whether the Revised Sociosexual Orientation Inventory (SOI-R) was invariant between Hispanic/Latina and Non-Hispanic White (NHW) undergraduate women. I performed confirmatory factor analysis to assess model fit and used increasingly restrictive models to test invariance. I included 208 Hispanic/Latina women and 190 NHW women. The CFI and RMSEA model fit statistics (CFI=0.98, RMSEA=0.06 (90% confidence interval=0.04-0.08, p-value=0.16) showed that the model fit well. I constrained factor loadings to be equal in both groups to test metric invariance. I observed non-significant differences in model fit (deltaX² (9)=88.67, p>0.95, deltaCFI=0.003, deltaRMSEA=-0.011). I also constrained intercepts to be equal to …

The Impacts Of Transfer Learning For Ungulate Recognition At Sevilleta National Wildlife Refuge, Michael Gurule

Geography ETDs

As camera traps have grown in popularity, their utilization has expanded to numerous fields, including wildlife research, conservation, and ecological studies. The information gathered using this equipment gives researchers a precise and comprehensive understanding about the activities of animals in their natural environments. For this type of data to be useful, camera trap images must be labeled so that the species in the images can be classified and counted. This has typically been done by teams of researchers and volunteers, and it can be said that the process is at best time-consuming. With recent developments in deep learning, the process …

High Altitude Exercise, Autophagy, And Angiogenesis, Quint Nikolas Berkemeier

Health, Exercise, and Sports Sciences ETDs

Environmental hypoxia, as a result of decreased barometric pressure upon ascent to high altitudes (>2500m) presents increased physiological demands compared to low altitudes. Competitive athletes, mountaineers, wildland firefighters, military personnel, miners, and outdoor enthusiasts commonly participate in, or are exposed to, forms of exercise or physical labor at moderate to high altitudes. Interestingly, however, the majority of research on intermittent hypoxic exposure is centered around hematological markers and the skeletal muscle cellular responses to exercise in hypoxic environments remain largely unknown. Two processes that are integral for maintenance of cellular health in skeletal muscle include autophagy and angiogenesis. We …

Examining Potential Trade-Offs Between Pest Management And Pollination To Sunflower Production In Nebraska, Luis Ochoa Cadena

Department of Entomology: Dissertations, Theses, and Student Research

Sunflower (Helianthus annuus) is cultivated for oil and seed production worldwide, and the United States produces 2.5% of the world’s oilseed sunflower primarily grown in the Great Plains. In 2022, oilseed and confectionary U.S. sunflower production increased by 48 and 44%, respectively, compared to last year's records. However, sunflower production can be seriously compromised by insect pests. The red sunflower seed weevil (Smicronyx fulvus LeConte) is considered the most serious pests in North America and causes severe economic damage yearly. On the other hand, native bees contribute substantially to sunflower yield. Currently, insecticide applications are the primary tool to suppress …

Attitudes Towards Public Basic Needs Programs: An Analysis Of Question Order Effect, Period And Cohort Changes, And Differences Across Religious Traditions, Jamy K. Rentschler

Department of Sociology: Dissertations, Theses, and Student Research

This dissertation examines public opinions towards public basic needs programs (PBNPs), focusing specifically on differences in attitudes towards spending on assistance to the poor (ATP) and welfare. To do this, I use two different approaches, one focusing on survey methodology and the other looking at social change across time and religious tradition. The first research question addresses potential survey question order effects based upon which question came first, ATP or welfare, and examines how other federal spending priorities may impact opinions towards welfare. I do find question order effects, some of which vary based on the respondent’s race, but the …

Positioning Undergraduate Learning Assistants In Instruction: A Case Study Of The La Role In Active Learning Mathematics Classrooms At The University Of Nebraska–Lincoln, Rachel Funk

Department of Mathematics: Dissertations, Theses, and Student Research

Research suggests learning assistant (LA) programs can be a change lever to support the institutionalization of active learning in postsecondary education. Some research suggests LAs offer unique benefits for STEM courses, independent from other change levers, but more research needs to be done to understand how LAs support active learning classrooms, specifically in mathematics. Research on mathematics instruction and the use of reform resources suggests that the successful implementation of reforms is impacted by perceptions individuals hold about that resource, such as the LA role. Yet, there is little research about the LA role in mathematics, particularly where the instructor …

Graft-Versus-Host Disease: Teaching Old Drugs New Tricks At Less Cost, Shatha Farhan, Shernan G. Holtan

Hematology/Oncology Articles

Graft-versus-host disease (GVHD) remains a major cause of morbidity and mortality after allogeneic stem cell transplantation (SCT). Currently, more patients can receive SCT. This is attributed to the use of reduced intensity regimens and the use of different GVHD prophylaxis that breaks the barrier of human leukocyte antigen, allowing an increase in the donor pool. Once an area with relatively few clinical trial options, there has been an increase in interest in GVHD prophylaxis and treatment, which has led to many US Food and Drug Administration (FDA) approvals. Although there is considerable excitement over novel therapies, many patients may not …

Reconsidering Fertility Imagery In The Murals Of Teotihuacan, Grace T.O. Ray

Theses

This thesis explores fertility imagery in the Tepantitla Paradise and Tetitla Goddess murals of ancient Teotihuacan in Mexico. In the beginning of the 1970s, these murals had been utilized as case studies in the assertion for the existence of a central female deity known as the Great Goddess, based on an abundance of fertility imagery within the scenes. Scholarship in the field has since discredited this theory, but the deity in the murals remains unidentified. In addition, the city does not offer surviving written texts to provide context for cosmological beliefs, only Teotihuacan’s vibrant material culture was left behind after …
