Vole Population Dynamics In Cover Crops Transitioning To Soybeans With Integrated Pest Management By Habitat Modification, Jena L. Nierman

Theses and Dissertations--Forestry and Natural Resources

The use of cover crops has been a wildly used method in rotational row crop production. Cover crops have minimized soil runoff and aided in maintaining nutrients in agricultural fields. Increased use of cover crops has seen a corresponding increase in the amount of damage done to soybeans by voles. Currently, there are no mitigation methods that successfully decrease vole populations in agricultural fields. The use of habitat manipulation as an integrated pest management solution has not been studied as a practical solution for vole population management. During 2019 and 2020, I tested the impacts of various cover crop termination …

Quantifying The Source And Pathway Of Dissolved Reactive Phosphate In Karst Drainage Of The Inner-Bluegrass, Cory Radcliff

Theses and Dissertations--Biosystems and Agricultural Engineering

In the Midwestern U.S. seasonal hypoxia experienced in the Gulf of Mexico and harmful algal blooms in inland freshwater ponds, lakes, and rivers are partly fueled by dissolved orthophosphate loadings from disturbed landscapes. Efforts to reduce dissolved reactive phosphate (DRP) loadings have had varying levels of success and have led to insufficient water quality improvements. Inefficiencies in conservation strategies can stem from poor understanding of phosphate source and flow pathway dynamics. This study focused on monitoring sources and flow pathways of dissolved reactive P in a karst agroecosystem with phosphatic limestone. We collected event water samples at the Camden Creek …

Extraction Of Micro- And Nano-Plastic Particles From Water Using Hydrophobic Natural Deep Eutectic Solvents, Jameson R. Hunter

Theses and Dissertations--Biosystems and Agricultural Engineering

The production of plastic and the amount of waste plastic that enters the environment increases every year. Synthetic polymers will gradually break down into particles on the micro- and nano-scale. The micro- and nano-plastics pose a significant ecological harm by transporting toxic chemicals and causing inflammation and cellular damage when ingested. Two common plastics are polyethylene terephthalate (PET) and Polystyrene (PS), and a newer bioplastic polylactic acid (PLA) that has become a popular alternative. Deep eutectic solvents are a recently discovered solvent composed of a hydrogen bond donor and hydrogen bond acceptor and have been proposed as a cheaper alternative …

Characterization And Upgrade Of Endocarp Biomass Derived Lignin To Value Added Products, Makua Vin-Nnajiofor

Theses and Dissertations--Biosystems and Agricultural Engineering

Lignin is an abundant biopolymer and a promising source of feedstock for high-value chemicals and energy materials, however, application methods of lignin into valuable products is yet to be fully explored. This study explores the valorization of lignin derived from lignin-rich endocarp biomass through the development of lignin-derived electrode materials. The chemical composition and cellular structure of the endocarps were characterized using HPLC and scanning electron microscopy (SEM) imaging. Mechanical properties of walnut and peach endocarps and preprocessing requirements were investigated using nanoindentation and specific energy consumption during grinding. Next, lignin was extracted from endocarps using deep eutectic solvent and …

Modeling Energy Flows In Floating In-Pond Raceways Utilizing Solar Power Back-Up, Bo Smith

Theses and Dissertations--Biosystems and Agricultural Engineering

The In-pond Raceway (IPR) is a novel option for production aquaculture, depending on water moving devices to provide constant flow. Device failure may result in catastrophic fish loss, requiring power backup systems to mitigate risk in case of power outages. Because these systems must be dependable and many suitable locations are remote, off-grid solar photovoltaic (PV) systems with battery storage have been considered since they eliminate need for utility power. Such systems can be hard to size and expensive. This study modeled system requirements using an energy balance to determine whether systems could withstand varying loads based on climatological conditions. …

Southern Pine Beetle-Specific Rna Interference Demonstrates No Effects On Nontarget Insects, Hannah Marie Hollowell

Theses and Dissertations--Entomology

The endemic southern pine beetle (SPB), Dendroctonus frontalis Zimmermann, is a highly destructive bark beetle that has devastated coniferous forests of the southern United States for decades. Traditional management strategies have been unable to respond effectively to largescale SPB outbreaks, prompting exploration of novel techniques including RNA interference (RNAi). Double-stranded RNAs (dsRNAs) are effective at triggering gene silencing and inducing mortality in SPB, but determining delivery methods and demonstrating specificity of the treatments is necessary before this technology may progress to deployment.

I evaluated three SPB-specific dsRNAs on model nontarget insects to assess potential lethal effects, sublethal effects such as …

Distribution And Diversity Of Heliothine And Other Lepidopteran Nudiviruses, Emrah Ozel

Theses and Dissertations--Entomology

Helicoverpa zea nudivirus 2 (HzNV-2) is the only known sterilizing and sexually-transmitted insect virus and causes pathological symptoms in H. zea reproductive tissues. HzNV-2 has features that make it a candidate as a H. zea (corn earworm) control agent, such as the ability to cause asymptomatic (latent) and symptomatic (lytic) infections and the ability to influence mating behavior of its host to favor virus spread. HzNV pathology has been studied and its genome sequenced, however, its prevalence in natural populations is largely unknown. In this study, we developed and used a low-cost PCR-based molecular survey to investigate HzNV-2 prevalence and …

Evaluating Antecedents To Treatment Success In Juveniles With Sexually Problematic Behavior, Alexandra P. Pappas

PCOM Psychology Dissertations

The impact of rape and other sexual offenses represents a major problem in society and can lead to chronic and harmful physical, psychological, and social consequences. Juveniles (younger than 18 years old) account for 20% of sexual offense arrests in the United States, with 96% of reported cases committed by male perpetrators. Risk indicators and characteristics of juveniles who sexually offend include demographic factors (e.g., history of sexual abuse), personality factors (e.g., antisocial behavior), and below average intelligence and cognitive functioning. Treatment of problematic sexual behavior in juveniles varies in intensity, structure, and level of supervision, though research investigating unsuccessful …

A Philosopher Looks At The Natural World: Twenty-One Acres Of Common Ground, Daniel Clifford Fouke

Books and Book Chapters by University of Dayton Faculty

Having purchased a moldy, concrete-walled underground house built in the 1970s on a 21-acre parcel infested with invasive plants but overlooking a national scenic river, a philosophy professor and his wife undertake a decades-long effort they didn’t predict. In this memoir, still in manuscript form, Daniel Fouke looks back at their first day on the land and recounts the journey. He writes, “Since I am a professional philosopher who has concentrated on environmental philosophy in the later part of my career, I will both provide a narrative of our journey and attempt to describe the philosophical lessons I’ve drawn from …

Unmanned Aerial Vehicles In Opportunistic Networks, Salih Safa Bacanli

Electronic Theses and Dissertations, 2020-2023

This dissertation presents novel algorithms for utilizing unmanned aerial vehicles (UAVs) through various scenarios within opportunistic networks. The opportunistic networks are considered challenging due to the intermittent and unreliable communication between nodes. UAVs can be used for delivering packets within opportunistic networks that can alleviate communication issues. We start examining the UAV usage in opportunistic networks by first investigating their effectiveness and proposing a UAV scanning approach. To validate the usage of UAVs, we evaluated the performance of an opportunistic network with and without using UAVs. The scanning techniques we investigated were random scan, meander scan, and our proposed approach …

U.S. Climate Litigation In The Age Of Trump: Full Term, Korey Silverman-Roati

Sabin Center for Climate Change Law

From beginning to end, the Trump administration pursued an agenda of climate deregulation. The administration aimed a portfolio of actions at weakening federal climate protections and promoting fossil fuels.1 The executive branch did so by aiming to revise and rescind all major Obama-era agency rules to regulate greenhouse gas emissions, leasing public lands for fossil fuel development, attempting to curtail climate impact consideration in National Environmental Policy Act and Endangered Species Act reviews, and withdrawing energy efficiency measures, among other climate deregulation actions.2 Collectively, this effort served to advance the view that humans are not causing serious climate change and …

The People's Court: On The Intellectual Origins Of American Judicial Power, Ian C. Bartrum

Dickinson Law Review (2017-Present)

This article enters into the modern debate between “consti- tutional departmentalists”—who contend that the executive and legislative branches share constitutional interpretive authority with the courts—and what are sometimes called “judicial supremacists.” After exploring the relevant history of political ideas, I join the modern minority of voices in the latter camp.

This is an intellectual history of two evolving political ideas—popular sovereignty and the separation of powers—which merged in the making of American judicial power, and I argue we can only understand the structural function of judicial review by bringing these ideas together into an integrated whole. Or, put another way, …

Libraries’ purposes of ensuring access to and preservation of information have been compromised as licensing increasingly replaces ownership. This article outlines various novel legal strategies that libraries could use to restore copyright’s intended balance, including antitrust, preemption, misuse, and unconscionability.

The Corruption Of Copyright And Returning It To Its Original Purposes, Michelle M. Wu

Georgetown Law Faculty Publications and Other Works

Since its inception, Copyright has had two purposes: the private interest of the author in being paid for her work and the public interest served by the dissemination of these works. Within the last two decades, though, some industries have systematically undermined both of those interests, redirecting the benefits of copyright towards themselves instead of the intended beneficiaries. This paper looks at the book, music, and entertainment industries, examines how copyright has been used to suppress the uses it was intended to foster, and explores ongoing and proposed avenues for course correction.

A Group-Protocol: Returning To Life Post Breast Cancer Treatment, Janice Finley, Ashley Timm

Occupational Therapy Capstones

The purpose of this project was to design a group protocol to assist breast cancer survivors living in the community to address unmet physical, cognitive, and psychosocial needs. There are more than 3.5 million breast cancer survivors within the United States today (American Cancer Society, n.d.). A cancer survivor's performance in meaningful occupations and roles need to be addressed as they learn to live with the long-term physical and psychosocial effects of treatments such as self-confidence and pain management (Burg et al., 2015; Kim, Kim, & Han, 2020). There is a lack of occupational therapy services for individuals diagnosed with …
