Economic Feasibility Of Aquaponics In The Cold-Climate Eastern United States: A Multi-Facility Monte Carlo Analysis, Ryan Nickerson May 2026

Economic Feasibility Of Aquaponics In The Cold-Climate Eastern United States: A Multi-Facility Monte Carlo Analysis, Ryan Nickerson

Master's Theses and Capstones

Most commercial aquaponics facilities fail to achieve profitability, and this challenge is exacerbated in cold climates, where heating, supplemental lighting, and insulated infrastructure inflate operating costs. Existing economic studies are dominated by warm-climate, single-facility cases, offering limited insight into whether cold-climate operators in the eastern United States can achieve profitability through design choices around scale, species selection, and labor optimization. This thesis evaluated the market feasibility of three research facilities (the University of New Hampshire, the University of Maryland, and Ohio State University) and one commercial facility in New Hampshire. The model used a discounted cash flow framework with parameters …

A Data-Driven Assessment Of Coastal Roadway Vulnerability Using Observed Storm Damage Locations, Jack Kearing May 2026

A Data-Driven Assessment Of Coastal Roadway Vulnerability Using Observed Storm Damage Locations, Jack Kearing

Master's Theses and Capstones

Coastal roadways are increasingly vulnerable to storm impacts and sea level rise. One common failure mode during these events is roadway washout, defined in this study as the physical loss or structural failure of roadway segments due to erosion, overtopping, or hydraulic failure. Washout events can disrupt transportation networks, restrict emergency access, and isolate coastal communities, highlighting the need for improved predictive methods that move beyond index-based assessments toward data-driven identification of vulnerable roadways.This study develops a data-driven framework for assessing roadway washout vulnerability using observed damage data and environmental predictors. Machine learning models, including random forest and decision tree …

Comparative Development Of Mof‑Based And Mof‑Free Agnp Functionalized Zno Nanorod–Cotton Fabric Composites For Photocatalytic Applications, Md Al Mamun May 2026

Comparative Development Of Mof‑Based And Mof‑Free Agnp Functionalized Zno Nanorod–Cotton Fabric Composites For Photocatalytic Applications, Md Al Mamun

Master's Theses

Photocatalysis offers a cost‑effective and environmentally friendly strategy for degrading organic pollutants and addressing energy and environmental challenges. This study initially explored MOF‑based cotton‑fabric‑supported ZnO nanorod composites but found that the MOF component primarily acted as an adsorbent rather than an effective photocatalyst. Consequently, MOF‑free composites were developed by directly growing ZnO nanorods on cotton fabric and functionalizing them with silver nanoparticles. Photocatalytic testing revealed that AgNP‑modified ZnO nanorods, particularly at 10 mM AgNP, exhibited superior dye degradation efficiency, thereby demonstrating a scalable and effective photocatalytic platform.

Morphological Variation Of Lingual Glands In Wild American Alligator (Alligator Mississippiensis) Populations, Benjamin Angalet May 2026

Morphological Variation Of Lingual Glands In Wild American Alligator (Alligator Mississippiensis) Populations, Benjamin Angalet

Master's Theses

American alligators (Alligator mississippiensis) inhabit diverse aquatic ecosystems including freshwater wetlands, swamps, and estuarine rivers. As apex predators, their physiological resilience has implications for ecosystem stability and long-term conservation. With projected sea-level rise and increasing saltwater intrusion into coastal freshwater habitats, understanding the osmoregulatory capacity of alligators is increasingly important. Unlike marine-tolerant crocodilians such as the saltwater crocodile (Crocodylus porosus), which possess specialized salt-secreting lingual glands in addition to renal and cloacal mechanisms, the morphology and physiological significance of lingual glands in wild American alligators remain poorly understood. This study examined lingual gland morphology and plasma …

Phase Separation Clustering Of Poly Ubiquitylated Cargos In Plasma Membrane Vesicle Trafficking, Il-Hyung Lee May 2026

Phase Separation Clustering Of Poly Ubiquitylated Cargos In Plasma Membrane Vesicle Trafficking, Il-Hyung Lee

Department of Chemistry and Biochemistry Faculty Scholarship and Creative Works

Phase separation is a process of molecular segregation in space. Increasing evidence suggests that spatial organization of biochemical molecules in cells is governed by the principle of phase separation. Multivalent binder proteins tend to form fluidic protein condensate and plasma membrane lipid composition tend to form lipid raft domain. On plasma membranes, the two types of phase separation is known to collaboratively segregate membrane cargo molecules leading to phase separation clustering. More evidence is being found that poly Ubiquitin (polyUB) proteins under certain circumstances have potency to phase separate into condensates. polyUB tagging of membrane proteins is often a first …

Personality Characteristics Of Emergency Nurses And Their Subjective Fit In The Emergency Department, Jose Michael Maria May 2026

Personality Characteristics Of Emergency Nurses And Their Subjective Fit In The Emergency Department, Jose Michael Maria

Theses & Dissertations

Nursing workforce challenges in the United States persist despite widespread recruitment and retention efforts, and the COVID-19 pandemic has further exacerbated shortages, turnover, and workforce instability. Despite interventions such as residency programs, financial incentives, and organizational initiatives, long-term retention remains inconsistent, particularly in high-demand settings like emergency departments. Ongoing issues such as overcrowding, rising patient acuity, and workforce attrition contribute to burnout, compassion fatigue, and compromised patient outcomes, perpetuating a cycle of staffing strain. Grounded in Person–Environment Fit theory, this research proposes that aligning emergency nurses’ personality traits with the specialty practice environment, the emergency department, may offer a more …

The Oncoming Light: An Experiential Approach To Psychological Exposition Through Dialogue-Driven Narrative, Benjamin G. Dewitt May 2026

The Oncoming Light: An Experiential Approach To Psychological Exposition Through Dialogue-Driven Narrative, Benjamin G. Dewitt

Honors Theses

Narrative is a lens through which we understand ourselves, our histories, our futures, and our ties to those around us. Narrative form has undergone vast transformations over time, and in the case of “postmodern” literature, pushes the boundaries of form into the experimental, questioning the truth of knowledge itself. While these experimental works can give rise to uniquely powerful emotional experiences, some components of narrative, when abandoned, may only hinder the immersion of the reader. This thesis evaluates several experimental, dialogue-driven narrative works against these components: linguistic, literal, emotional, and intellectual significance, in a hierarchy of importance as proposed by …

Synthesis Of Novel 1,2,3-Triarylnaphthalenes Via Intermolecular Dehydro-Diels-Alder Reaction, Ethan C. Dailey May 2026

Synthesis Of Novel 1,2,3-Triarylnaphthalenes Via Intermolecular Dehydro-Diels-Alder Reaction, Ethan C. Dailey

Honors Theses

The photo-dehydro-Diels–Alder (PDDA) reaction is a useful method for the construction of substituted naphthalene derivatives from acyclic precursors. While intramolecular variants of this transformation are well established, intermolecular PDDA reactions remain rare due to challenges associated with controlling reactivity under photochemical conditions. Previous studies suggest that electron-withdrawing substituents can promote intermolecular cycloaddition by increasing alkyne polarization and stabilizing reactive intermediates. In this work, the effect of enhanced electron-withdrawing character on intermolecular PDDA reactivity was investigated through the incorporation of a 2,3,5,6-tetrafluoropyridinyl substituent. Corresponding alkyne substrates were synthesized and subjected to photochemical conditions, resulting in the formation of 1,2,3-triarylnaphthalene products. The …

Belonging, Governance, And The Future Of The Nation: Rethinking Citizenship In Tribal Nation Communities, Meadow Carroll May 2026

Belonging, Governance, And The Future Of The Nation: Rethinking Citizenship In Tribal Nation Communities, Meadow Carroll

Honors Theses

Tribal citizenship is often framed as a question of identity or legal status, but it functions more fundamentally as a structure of governance that determines who participates in political life and whether nations can sustain themselves over time. This study compares the citizenship frameworks of the Cheyenne and Arapaho Tribes and the Cherokee Nation to examine how different enrollment criteria shape political participation, demographic continuity, and institutional capacity. Drawing on tribal constitutions, enrollment materials, governance records, and voter participation data, the analysis demonstrates that citizenship systems produce measurable differences in how tribal governments function in practice. Systems based on fixed …

Creative Nonfiction Essays, Colby S. Langley May 2026

Creative Nonfiction Essays, Colby S. Langley

Honors Theses

To write about the present with any authority requires a keen eye for the past. To write from our lives into meaningful creative nonfiction requires a firm understanding that experience is the composite of life experience blending into the current moment. The writing is then drawn irreversibly towards emotion: indulgent and oppressive. The extremity of emotion dictates the difficulty of transcribing the experience onto the page, and violence is a source of both extreme emotion and experience. It is important to note that I am primarily considering personal violence for this essay, while societal and institutional violence have their own …

A Narrative Of The Plague Doctor And How Its Historical Context Translates To The Modern View Of The Plague Doctor, Callie P. Johnston

Honors Theses

The Plague Doctor was once a historical figure who practiced medicine primarily on those infected with the bubonic plague. The plague doctor, as a historical figure and physician, has been transformed in modern culture and media. Originally perceived as a harbinger of both hope and death, the Plague Doctor has undergone a historical transformation from a masked physician to a more stylized character that appears in modern media, digital art, toys, costumes, video games, and popular culture. This thesis examines the evolution of the Plague Doctor from its historical role as a plague physician to its current iconography as a …

Dissociation, Anxiety, And The Vestibular System: Understanding The Impacts Of Anxiety, Panic, And Dissociation On The Vestibular System, Julian Achata

Honors Theses

Previous research indicates that vestibular dysfunction is associated with symptoms of anxiety, panic, and dissociation. The present study will investigate anxiety, panic, and dissociation symptoms and identify the connections between reported symptom severity and vestibular functionality. This study will focus on three different hypotheses: 1) higher levels of dissociation will correlate with increased vestibular disruption; 2) higher levels of anxiety will correlate with increased vestibular disruption; 3) higher levels of panic will correlate with increased vestibular disruption. Six virtually administered self-report measurements were used to identify the variables: Beck Anxiety Inventory (BAI), Depersonalization Derealization Inventory (DDI), Dissociation Experiences Scale-II (DES-II), …

Resilience By Living With The Land And Community: A Case Study Of A Local Food Forest, Olivia Beck

Honors Theses

Imagine a public space where food, leisure, outdoor activity, and community engagement occur in one place, all in an urban forest ecosystem. For many, this is a hopeful vision of the future, and that is exactly what the idea of an urban food forest provides. In agroecology, a food forest or forest garden consists of planting diverse edible plants and mimicking the patterns of natural ecosystems. The intricate planning and design ensure the forest is self-sustaining, much like a natural forest, making it very resilient once established. However, they face many challenges and take time to grow and develop to …

A Meta-Analysis Of Endometrial Cancer Metabolites As Potential Non-Invasive Biomarkers, Makenna K. Johnson May 2026

A Meta-Analysis Of Endometrial Cancer Metabolites As Potential Non-Invasive Biomarkers, Makenna K. Johnson

Honors Theses

Endometrial Cancer (EC) is the most prevalent gynecological cancer in the United States and causes tens of thousands of deaths. Despite its massive negative impact in developed countries, there currently is no reliable screening tool used to diagnose women. Due to this urgent need for minimally invasive and precise techniques to diagnose this malignancy, the metabolomics field has been at the forefront of current research. An untargeted mass-spectrometry approach is used by many researchers to form an initial hypothesis as to which metabolites are key in identifying EC cases. However, there are sometimes inconsistencies between studies. A meta-analysis approach examines …

Contrasting Roles Of Downed Wood And Leaf Litter In Structuring Aphaenogaster Ants And Other Forest-Floor Arthropod Communities, Danielle E. Dolan May 2026

Contrasting Roles Of Downed Wood And Leaf Litter In Structuring Aphaenogaster Ants And Other Forest-Floor Arthropod Communities, Danielle E. Dolan

Great Lakes Center Masters Theses

Forest floors are dynamic and spatially heterogenous landscapes characterized by differing amounts of light, temperature, and moisture. Bounded substrates, like downed wood and leaf litter, add further complexity to this landscape. Specifically, downed wood is noted for its ability to retain a higher moisture level than the surrounding environment, and as such can serve as an ideal microhabitat for desiccation intolerant organisms (e.g., salamanders and eusocial insects). Here, I attempt to disentangle the relationship between forest floor arthropods and microhabitat selection (i.e., downed wood vs leaf litter) on a northeastern forest floor. The ant, Aphaenogaster picea, was chosen as my …
