Warming Temperatures Increase Microbial Consumption Of Marine Organic Matter, Sarah Benson

Master's Theses and Capstones

Marine microbes are vital to oceanic ecosystems and influence the global climate through their paramount role in Earth’s biogeochemical cycles. With this intricate role in ecosystems, it is important to understand the effect of increasing ocean temperatures on the cycling of organic matter (OM), which is hypothesized to contribute a positive feedback to future warming via an acceleration in microbial respiration of OM to CO2. We experimentally investigated the temperature sensitivity of microbial consumption of marine particulate OM focused in the rapidly warming Gulf of Maine during the 2019 and 2020 Fall phytoplankton bloom. The overall rate and quantity of …

An Assessment Of The Use Of Green Stormwater Infrastructure For Flood Mitigation At Berry Brook, Rachel Lynn Hastings

Master's Theses and Capstones

This research examined the effectiveness of GSI and other BMPs to control urban flooding for extreme precipitation events and compared the impacts of increasing impervious cover with the impacts of increasing rainfall intensity caused by climate change. The City of Dover has spent the last decade implementing best management practices in the 185-acre Berry Brook watershed to combat stream pollution and flooding caused by urbanization. Improvements to the watershed included building additional headwater wetland area, daylighting and restoring 1,100 feet of stream, and redirecting stormwater to GSIs, thereby reducing the effective impervious cover from 30% to 10%. Four PCSWMM models …

Where Do You Look? Relating Visual Attention To Learning Outcomes And Url Parsing, Niveta Ramkumar

Master's Theses and Capstones

Visual behavior provides a dynamic trail of where attention is directed. It is considered the behavioral interface between engagement and gaining information, and researchers have used it for several decades to study user's behavior. This thesis focuses on employing visual attention to understand user's behavior in two contexts: 3D learning and gauging URL safety. Such understanding is valuable for improving interactive tools and interface designs. In the first chapter, we present results from studying learners' visual behavior while engaging with tangible and virtual 3D representations of objects. This is a replication of a recent study, and we extended it using …

The Contribution Of Tgbdp5 To Gene Regulation In The Acute Stage Of Toxoplasma, Julia Heffernan

Master's Theses and Capstones

Toxoplasmosis, caused by the parasite Toxoplasma gondii, is a highly prevalent disease found on every content. An estimated 20-40% of the United States’ population is infected with the parasite according to IgG seroprevalence. There are two stages of Toxoplasma that cause disease, tachyzoites which cause the acute phase and the bradyzoites which cause the chronic phase. The chronic stage will persist for a life-long infection which can reactivate to tachyzoites if the host becomes immunocompromised, leading to encephalitis and heart failure. Current drug therapies clinically approved to treat Toxoplasma can only target tachyzoites and can cause adverse reactions. Therefore, the …

Progress On The Use Of Surface-Immobilized Elastin-Like Polymers As A Stimuli-Responsive Biosensor For Interleukin-6 Detection, Marissa Morales

Doctoral Dissertations

Elastin-Like-Polymers (ELPs) are intrinsically disordered biopolymers with an amino acid structure comprised of the pentapeptide repeat sequence [VPGXG]n (V = valine, P = proline, G = glycine, X = guest residue, and n = total number of repeat sequences). ELPs are stimuli-responsive meaning below their transition temperature, ELPs are structurally disordered, highly solvated, and soluble in aqueous solutions. Above their transition temperature, ELPs experience coalescence and phase separation as intermolecular and intramolecular contacts form within the hydrophobic regions of the ELPs. The transition temperature of ELPs is influenced by the hydrophobic surface area, as well as changing solvent conditions including …

Mathematical Analysis Of A Model Of Blood Flow Through A Channel With Flexible Walls, Madeline Mayes Edwards

Doctoral Dissertations

The present research is devoted to the problem of stability of the fluid flow moving in a channel with flexible walls and interacting with the walls. The walls of the vessel conveying fluid are subject to traveling waves. Experimental data shows that the energy of the flowing fluid can be transferred and consumed by the structure (the walls), which induces “traveling wave flutter.” The problem of stability of fluid-structure interaction splits into two parts: (i) stability of fluid flow in the channel with harmonically moving walls and (ii) stability of solid structure participating in the energy exchange with the flow. …

Life, Liberty, And The Pursuit Of Police Officer Acquittals: Jurors' Explicit And Implicit Racism, Donovan Corson Kelley

Doctoral Dissertations

Less than .001% of cases involving police officers killing suspects result in trial convictions; acquittals are significantly higher for Black victims than for White victims. The purpose of this dissertation was to examine if explicit and implicit racism amongst jurors helped explain why police officers are rarely convicted of murder, especially in cases with Black victims. In a pilot study in which mock jurors read a trial summary involving an officer killing an unarmed victim who was either Black or White, jurors were more likely acquit officers on trial for killing a Black victim than a White victim. In Study …

Molecular Simulation Studies Of Dynamics And Interactions In Nucleic Acids, Lev Levintov

Doctoral Dissertations

In my thesis work, I conducted molecular simulation studies to explore dynamics and interactions in nucleic acids. I began my work by applying conventional molecular dynamics (MD) simulations to study the local and global dynamics of the transactivation response (TAR) element from the type-1 human immunodeficiency virus (HIV-1) and the effect of binding of ligands on the dynamics of TAR RNA. I determined that the TAR RNA structure was stabilized on binding of ligands due to the decreased flexibility in helices that comprise TAR RNA. This rigidity of the TAR RNA structure was coupled with the decreased flipping of bulge …

Structural And Binding Studies Of The Polar Organizing Protein Z (Popz) Using Nmr Spectroscopy, Christopher Taylor Nordyke

Doctoral Dissertations

The polar organizing protein Z (PopZ) is an intrinsically disordered protein from Caulobacter crescentus that is necessary for the formation of three-dimensional microdomains at the cell poles, where it functions as a hub protein that recruits multiple regulatory proteins. Although a large portion of the protein is predicted to be disordered, PopZ can self-assemble into polymeric superstructure scaffolds that directly bind to at least ten different proteins. Here, we report the solution NMR structure of PopZΔ134–177, a truncated variant of PopZ that does not self-assemble but retains the ability to interact with heterologous proteins. We show that the unbound form …

"I Know You're Family": An Exploration Of The Enduring Relevance Of A Pre-College Summer Bridge Program For Underrepresented Minoritized Students, Kathryn Slater

Doctoral Dissertations

The proposed dissertation investigates the enduring relevance of a pre-college summer bridge program for underrepresented minoritized (URM) students who participate in the program as an entry point into a predominantly White institution (PWI). Using narrative inquiry and a critical frame, this dissertation uses individual interviewing and focus group data to understand the experiences of 10 URM summer bridge program participants at different points in their undergraduate academic career. For the purposes of this study, relevance of a summer bridge program for URM students refers to the ways in which deliberate and proactive programming helps students to develop academic and socio-emotional …

Development Of Open Lactam And Captopril Analogues For The Covalent Inhibition Of Metallo-Β-Lactamases, Marie-Josiane Ohoueu

Doctoral Dissertations

ABSTRACT DEVELOPMENT OF OPEN LACTAM AND CAPTOPRIL ANALOGUES FOR THE COVALENT INHIBITION OF METALLO-β-LACTAMASES

ByMARIE-JOSIANE OHOUEU University of New Hampshire, May 2021 The synthesis of a series of compounds designed to act as inhibitors of metallo-β-lactamase enzymes (MBLs), a sub-class of β-lactamases found in several clinically difficult to treat bacteria that are responsible for the widespread β-lactam antibiotic resistance, are described. The strategy involves the introduction of a functional group, such as an epoxide or thiirane, in the designed inhibitors capable of covalently binding the MBL targets and shutting them down irreversibly. This would prevent the enzymes from hydrolyzing the …

Pews, Proprietors, And Plutocracy: The Business Model Of Unitarian And Congregational Religious Societies In Northern New England, 1790-1850, Amy Beth Smith

Doctoral Dissertations

This dissertation examines Unitarian and Congregational religious societies in northern New England port cities from 1790-1850 and argues that pew proprietorship created a plutocracy, which resulted in the development of a corporate character for Protestant churches and a prioritization of secular over theological concerns. Scholarship on Protestant New England churches during the Early Republic is sorely lacking and historians need a greater understanding of the role proprietors played in church affairs. In the antebellum period, wealthy Protestant elites in Portland, Maine, Portsmouth, New Hampshire, and Boston, Massachusetts consolidated their power through the purchase of pews, which provided them proportional control …

Nanoelectronic Devices For Sensitive Detection Of Biomarkers In Healthcare Monitoring, Md Niazul Islam Khan

Doctoral Dissertations

In recent years, biosensors have seen an exponential rise of their applications in a number of fields including the field of health care monitoring, particularly in point-of-care diagnostics. With the contemporary rise of nanotechnology, these biosensors have experienced an ever-growing inclusion of nano scale electronic devices or nanoelectronic devices to exploit the plethora of advantages of nanoelectronics. The performances of these nanoelectronic devices, however, largely depend on the nanomaterials used. Especially, carbon-based nanomaterials such as carbon nanotubes (CNTs) and graphene have proven to be superior candidates compared to others because of their multitude of electronic and mechanical properties suitable for …

Discourses Of Diversity: A Qualitative Case Study Of World Language Pedagogies Through An Intersectional Lens, Sheri Dion

Doctoral Dissertations

Schools are becoming more linguistically and racially diverse in K-12 settings, yet there is relatively little research that explores how language teachers incorporate student and community diversities in their pedagogies. Situated at one, northeastern public secondary school in the United States, this research offers a qualitative case study of language pedagogies through an intersectional lens to investigate the mechanisms and contexts through which inequities arise. Data is collected from the following sources: teacher interviews, classroom observations, teachers’ syllabi, and student de-identified work. This study employs intersectionality (Collins & Bilge, 2016; Crenshaw, 1989, 2010) as a primary theoretical lens and critical …

Justice System Outcomes Of Children Referred For Sexual Offenses, Kei Saito

Doctoral Dissertations

The proliferation of increasingly punitive sex crime legislation in the United States have extended to include children adjudicated of sexual offenses. Using data from the Florida Department of Juvenile Justice, this dissertation examined the impact of three factors on sentencing outcomes for children referred for illegal sexual behaviors: race, same-sex victim, and county of referral. (1) Black children were disproportionately arrested for sexual offenses compared to any other racial/ethnic group. However, Black children in the sample were less likely to face harsher outcomes compared to Caucasian children, such as adjudication and ordered to register as a sex offender. (2) Children …

Diversity In The Commercial Sexual Exploitation Of Children In The Us, Brianna Ferreira

Master's Theses and Capstones

Researchers have examined the commercial sexual exploitation of children (CSEC), however, they tend to focus on a stereotypical victim. Little research exists on the diversity of CSEC, and the various forms that it can encompass. This secondary data analysis examines the diversity in United States CSEC cases by using Mitchell, Finkelhor, and Wolak’s (2010) National Juvenile Prostitution Study (NJPS) case narratives. The current study uses thematic analysis to analyze the 132 NJPS case narratives. Seven major overarching themes of diversity emerged throughout the research process: (1) Facilitator/Relationship of Facilitator and Dynamics, (2) Gender of Juvenile, (3) Reason for Engagement: Risk …

Restoration Of Native Plant Communities In Sand Dune Systems Of Plum Island, Newbury, Massachusetts, Natalie Feldsine

Master's Theses and Capstones

The impacts of Superstorm Sandy on coastal resources of the eastern United States have brought the importance of resilient sand dune systems into focus. While dunes are primarily dominated by American beachgrass (Ammophila breviligulata), a host of other native species commonly occur in these systems, providing diversity and habitat complexity that is often not recognized or incorporated into dune restoration initiatives, and could benefit sites where dune dieout is a concern. Dieout refers to the death of A. breviligulata occurring in large patches. The goal of this study was to explore the importance of biodiversity on dune resiliency by using …

Factors Affecting Purchase Of Locally Grown Produce: A Case Study Of New Hampshire Markets, Jordan Strater

Master's Theses and Capstones

There has been a recent focus on expanding local agriculture production in New Hampshire, and more information on consumer decision making in regard to local food purchasing is needed. Expansion of local food production and consumption has been of great interest in the past several years, with many consumers becoming increasingly curious about where their food comes from. Concerns about disease, environmental damage, fossil fuel usage, and recently food chain disruption due to COVID-19 as well as the health of local economies have fostered this awareness about the origins of our food (Onozaka et al. 2010; Thilmany et al. 2020). …

Abortion Restrictions During A Pandemic At The Intersection Of The 13th Amendment And Electoral Legislation, Dr. Cynthia Boyer

The University of New Hampshire Law Review

The current pandemic is intensifying restrictions on a wide range of fundamental rights which form a key pillar of the rule of law, it includes access to reproductive rights. Some states have moved forward with their ideological quest of control and infringement of constitutional rights in order to ban or limit abortion what is a fundamental attack on constitutional rights and in particular those associated with the Thirteenth Amendment. These restrictions on abortion resulting from the proclamation of a state of emergency follow the path already taken by certain states to reinforce their coercive measures. They raise major legal and …

Going Viral?: Discouraging The Premature Use Of Civil Liability Strategies As A Response To Covid-19, Michelle L. Richards

The University of New Hampshire Law Review

In addition to the myriad of issues caused by the COVID-19 pandemic in the United States, the virus has also placed our legal system in a position of creating problems that can contribute to the spread of this pandemic. Despite the fact that the United States has been mired in the COVID-19 pandemic and vaccine strategies have been recently developed to provide protection from this virus, much is still unknown about the etiology of this virus and how to effectively control its spread. As a result, public health agencies at the federal, state, and local levels have only been able …

Enhancing Precoat Filtration Removals Of Selected Dissolved And Microbial Contaminants, Kathryn Quay

Master's Theses and Capstones

Arsenic contamination in drinking water is a worldwide public health concern. Contamination occurs from both natural and anthropogenic sources and is associated with serious acute and chronic health effects. In 2001, the Environmental Protection Agency (EPA) changed the maximum contaminant level (MCL) of arsenic from 50 to 10 μg/L. Because of this, there have been incentives for further research and development of cost-effective technologies to help meet these new standards, especially in small community water systems.Over the past decade, attention has turned to zero-valent iron (ZVI) as a possible arsenic removal material because of its efficient, inexpensive, and locally available …

Accumulation Of Cyanobacteria Toxins In Lettuce And Radishes Exposed To Water And Aerosols From A Low-Toxin Lake, Anne C. Ewert

Master's Theses and Capstones

Cyanobacteria are the oldest known photosynthetic organisms on Earth. They are found in a wide range of habitats worldwide but have recently become an increasing issue in both freshwater and marine systems due to anthropogenic eutrophication and climate change. Cyanobacteria produce an array of toxins harmful to wildlife and humans, some of which have been found to accumulate in plant and animal tissues. Microcystins (MCs) are the most common toxins produced, occurring in 40 – 75% of cyanobacteria blooms worldwide. They are highly stable, water and fat soluble, cyclic heptapeptides that cause acute toxicity in the liver by the inhibition …
