Soil Profile Properties And Greenhouse Gas Emissions As Influenced By Long-Term Cattle Manure And Inorganic Fertilizer Applications Under Corn-Soybean-Spring Wheat Rotation In Eastern South Dakota, Anuoluwa Ojonoka Sangotayo

Electronic Theses and Dissertations

The application of manure and inorganic fertilizer in row crops may significantly influence soil and greenhouse gas (GHG) emissions. Understanding the long-term influence of these management practices on soil pore characteristics, hydro-physical properties and greenhouse gas emission is essential in developing proper conservation practices. However, there is limited information on the impact of cattle manure and inorganic fertilizer application on soil hydro-physical properties, soil pore characteristics at lower depths and surface GHGs emissions. Therefore, the objectives of this study were to; (i) utilize X-ray computed tomography (XCT) technique to quantify the impact of manure and fertilizer amendments under a corn …

The Live Bait Trade As A Pathway Of Inland Invasive Fish Species Introductions, Hannah Mulligan

Electronic Theses and Dissertations

Freshwater systems are susceptible to numerous anthropogenic pathways of invasive species introductions and subsequent establishment. Once establishment occurs, invasive species not only impact biodiversity, ecosystem function, and human health, but also cost the global economy billions of dollars every year. Recreational fishing is one of the most prevalent pathways for invasive species introductions in freshwater systems due to increased propagule pressure from boating and angling activity. Within recreational fishing, the live bait trade represents a secondary pathway whereby anglers illegally release baitfish (and water) that may contain invasive species. Preventative actions, including regulations, education, and inspections have been implemented to …

Understanding The Role Of Hba/Hbd Variations On Deep Eutectic Solvent Properties And Activity Using Acetylsalicylic Acid As A Model Drug, Michael Frimpong

Electronic Theses and Dissertations

Deep eutectic solvents (DES) are emerging as a versatile class of solvents, attracting considerable attention for their unique solvent properties and potential applications. This study examines the effects of variations in combinations as well as molar ratios of hydrogen-bond acceptor (HBA) and hydrogen-bond donor (HBD) on the structure of DES. It further explores the structure-activity relationship, measured using the rate of acetylsalicylic acid (ASA) degradation in the solvent. The project is based on the model that variations in HBA/HBD combinations and their relative molar ratios impact the solvent structure (hydrogen bonding), observable in physicochemical measurements, infrared (IR), and nuclear magnetic …

Modulatory Effects Of Deacetylated Sialic Acids On Breast Cancer Resistance Protein-Mediated Multidrug Resistance And Receptor Tyrosine Kinase-Targeted Therapy, Isaac Tuffour

Electronic Theses and Dissertations

Multidrug resistance (MDR) remains a major challenge in cancer treatment, accounting for over 90% of chemotherapeutic failures. Cancers utilize sugar residues to engage in multidrug resistance. The underlying mechanism of action involving glycans, specifically the glycan sialic acid (Sia) and its various functional group alterations, has not been explored. ATP-binding cassette (ABC) transporter proteins, key proteins utilized by cancers to engage in MDR pathways, contain Sias in their extracellular domains. Modulating the expression of acetylated-Sias on Breast Cancer Resistance Protein (BCRP), a significant ABC transporter implicated in MDR, in lung and colon cancer cells directly impacted the ability of cancer …

Ecological Impacts Of Anthropogenic Chemicals On Non-Target Species And The Role Of Plant Diversity In Ecosystem Restoration And Resilience, Shiva Torabian

Electronic Theses and Dissertations

Understanding ecosystem processes in rangelands is of paramount importance for ensuring global food security, given their pivotal role in sustaining forage and livestock production. Central to this understanding are fundamental processes such as nutrient cycling, decomposition, and plant biomass dynamics. However, the use of anthropogenic chemicals in agricultural practices has the potential to exert significant influence on these critical ecosystem functions. A pivotal factor in this context is the plant diversity inherent to these rangeland ecosystems. Plant diversity not only provides essential ecosystem functions but also enhances them with the capacity to withstand and recover from perturbations. Ecosystems characterized by …

Effects Of Agricultural Chemicals On Native Plants Of The Northern Great Plains, Gabrielle Bolwerk

Electronic Theses and Dissertations

Agricultural chemicals are ubiquitous on the Northern Great Plains landscape and have negative impacts on non-target plant communities, even at small doses. Northern Great Plains grassland plant communities may experience herbicide drift from agricultural fields or be subject to livestock pharmaceuticals in grazing lands. My research objective was to evaluate if and how native plants are affected by agricultural chemical presence at different concentrations. In Chapter 2, I studied the effect of different concentrations of three common agricultural herbicides (2,4-D, atrazine, and trifluralin) on the germination, emergence, and growth of native plant species of the Northern Great Plains. I performed …

Biological Control Of Bacterial Leaf Streak Of Wheat Using Antagonistic Rhizobacteria, Ashley Frederickson

Electronic Theses and Dissertations

Wheat (Triticum aestivum L.) is one of the world’s most valuable crops, and the primary food grain produced in the United States. A major disease in wheat production is Bacterial Leaf Streak (BLS) caused by the gram-negative bacterium Xanthomonas translucens pv. undulosa (Xtu). Very few management strategies are available to growers to manage this disease, as common chemicals do not provide adequate control. A number of studies have been conducted on biological control using Rhizospheric bacteria for the control of various plant diseases, but limited data is available on the efficacy of biological control using Rhizospheric bacteria for controlling Bacterial …

Unveiling Race Diversity And Fungicide Sensitivity Profiles Of Pyrenophora Tritici Repentis Populations In South Dakota Collected From 2021-2023, Jaswinder Kaur

Electronic Theses and Dissertations

Tan spot, a foliar disease of wheat caused by the ascomycetes fungus Pyrenophora tritici repentis (Ptr), poses a significant threat to wheat crops globally. The disease gained economic importance in the late 1970s due to shifts in farming practices, such as minimal tillage and planting on crop residues, providing favorable conditions for the pathogen to overwinter and cause infections. Ptr is classified into eight races based on the production of necrotrophic effectors—Ptr ToxA (necrosis-inducing), Ptr ToxB, and Ptr ToxC (chlorosis-inducing on respective susceptible and sensitive cultivars)—resulting in distinct symptoms on susceptible wheat differentials. The inverse gene-for-gene hypothesis of Ptr suggests …

Electrochemical Innovations: Advancements In Lithium Metal Batteries & Supercapacitor For Energy Storage, Jyotshna Pokharel

Electronic Theses and Dissertations

Constructing an artificial solid electrolyte interphase (SEI) on lithium metal electrode is a promising approach to address the rampant growth of dangerous lithium morphologies (dendritic and dead Li0) and low Coulombic efficiency that plague development of lithium metal batteries. But it is not known how the Li+ transfer behavior in the SEI is coupled with mechanical properties. We demonstrate here a facile and scalable solution-processed approach to form a Li3N-rich SEI with a phase-pure crystalline structure that minimizes the diffusion energy barrier of Li+ across the SEI. Compared with a polycrystalline Li3N SEI obtained from conventional approaches, our phase-pure/single crystalline …

A Qualitative Study Of Library Staff’S Understanding Of Disability And Attitudinal Barriers In Libraries, Lisa A. Ferrara

Theses and Dissertations

This applied dissertation was designed to examine how library staff understand disability and attitudinal barriers, and to learn how they use this information when planning and implementing library programs and services. Individuals with disabilities are an underserved population in libraries. Although they could benefit from the programs and services that libraries have to offer, individuals with disabilities often experience barriers to participation that prevent them from using libraries. One area that has been understudied is that of the attitudinal barriers experienced by individuals with disabilities.

Participants were recruited through professional library associations throughout the United States using a screening questionnaire. …

The Conflict Among African American Penal Interests: Rethinking Racial Equity In Criminal Procedure, Trevor George Gardner

Scholarship@WashULaw

This Article argues that neither the criminal justice reform platform nor the penal abolition platform shows the ambition necessary to advance each of the primary African American interests in penal administration. It contends, first, that abolitionists have rightly called for a more robust conceptualization of racial equity in criminal procedure. Racial equity in criminal procedure should be considered in terms of both process at the level of the individual, and the number of criminal procedures at the level of the racial group—in terms of both the quality and “quantity” of stops, arrests, convictions, and the criminal sentencings that result in …

Lessons Learned In Prison, Daniel Keating

Scholarship@WashULaw

One way that I have tried to stay fresh as a teacher through the decades is to periodically force myself outside of my teaching comfort zone by trying something completely different. Sometimes these initiatives will end up being a one-time experiment. That was the case a little over ten years ago when I decided to teach a new course (Contracts) in a new format (online, but well before Zoom had become commonplace). Other times, my teaching experiment will prove to be more than just a frolic and detour, as was true eight years ago when I began offering a free …

Industry Groups In International Governance: A Framework For Reform, Melissa (M.J.) Durkee

Scholarship@WashULaw

The Sustainable Development Goals and the UN Guiding Principles on Business and Human Rights encourage engaging with businesses as partners in important global governance agendas. Indeed, many international organizations are now partnering with business groups to secure funding and private sector engagement. At the same time, reforms at the World Health Organization, Food and Agriculture Organization and others seek to restrain the dangers of mission distortion and capture by business groups. Shareholders at major multinational oil and gas companies also recognize these dangers and seek to rein in lobbying that is at odds with the goals of the Paris Climate …

The Impacts Of Siblings On Development Across The Lifespan, Jeanie K. Cox

Modern Psychological Studies

Most individuals grow up with siblings, and sibling relationships are some of the longest lasting relationships experienced. Studies that have investigated sibling effects on developmental domains and stages throughout an individual’s life indicate that older siblings have some of the greatest impacts on younger siblings’ social, psychological, and cognitive development. During childhood, sibling relationships revolve around older and younger siblings’ prosocial behaviors. During adolescence, sibling power dynamics shift as older siblings relinquish power to younger siblings. In adulthood, siblings tend to experience increased closeness and decreased conflict as they mature and move away from one another. Information on siblings’ impacts …

Impact Of Pandemic Induced Stress On Health Behaviors Related To Covid-19 Susceptibility, Mahnoor Malik, Nicole Ryerson

Modern Psychological Studies

The COVID-19 pandemic has encompassed not only a public health crisis due to the range of symptoms and rapid spread associated with the SARS-CoV-2 virus, but it has also resulted in daily life changes due to public health mandates implemented to reduce the spread of the disease. The current study (N = 148) tested two hypotheses: that individuals experiencing increased stress due to the pandemic would be more likely to engage in protective behaviors that would limit exposure to the virus (e.g., limiting in-person contact) and that individuals experiencing increased stress would also engage in behaviors that may increase their …
