Melanin Pigments As Antibacterial Agents, Tahmineh Rahmani Eliato

Doctoral Dissertations

In this dissertation I investigated the structural properties of melanin biopigment from different sources as an antibacterial and endotoxin bonding agent. I extracted melanin from Equus ferus hair with acid hydrolysis (termed EquusMel) and characterized it by microscopic and spectroscopic techniques. Scanning electron microscopy (SEM) and transmission electron microscopy (TEM) revealed that EquusMel is mainly elliptical in shape with a mesoporous and layered structure within the individual particles. Wide-angle (WAXS) and small-angle (SAXS) X-ray scattering measurements demonstrated a semicrystalline multilayered structure with order spacing of 45.2 Å. Pore size distribution determined by the Barrett–Joyner–Halenda (BJH) method showed primary pores within …

“Test Run Or One And Done”: Gender Differences In Lgbtq+ Hookup Experiences, Della Burke

Doctoral Dissertations

This dissertation explores queer individuals’ participation within hookup culture, the goals and motivations of those taking part in queer hookup encounters, and the ways queer individuals make sense of their hookup experiences. I analyze data from 24 semi-structured qualitative in-person and online interviews to examine LGBTQ+-identified individuals’ experiences with queer hookup encounters. This dissertation offers several major contributions to the scholarship of LGBTQ+ hookup experiences. First, I find that participants talk about three discrete levels of intimacy: noncommittal hookups, “catching feelings,” and third, “real relationships” or emotional connections. Second, both men and women define hookups as noncommittal sexual encounters, but …

A Memory-Based Approach To Multiple Document Comprehension, Allison Sonia-Bolduc

Doctoral Dissertations

Multiple document (MD) comprehension is of growing interest in the Internet age, in which reading material is readily available from multiple sources. However, comprehension research has typically been dominated by studies investigating single documents (Bråten et al., 2019; McNamara & Magliano, 2009). This dissertation applies a memory-based approach traditionally used in research on single document comprehension to a MD context, with the goal of understanding the on-line processing and integration of information from multiple documents. Expository-style passages were created in which the first half contained information that was either consistent or inconsistent with a target sentence in the second half. …

Cryopreservation Studies Of An Antifreeze Protein From The Desert Beetle Anatolica Polita, Jonathan Sreter

Doctoral Dissertations

Antifreeze proteins (AFPs) are specialized evolutionary adaptations by certain cold climate organisms, including fish, plants, fungi, bacteria, and insects, to prevent cryo-injury. AFPs contribute to freeze resistance or tolerance by binding to the surface of ice crystals and preventing their growth, as well as inhibiting ice recrystallization (i.e., small crystals restructuring into large crystals) during large temperature fluctuations and constant sub-zero temperatures. AFPs have potential applications in cryopreservation and in the development of cryo-functional materials for medicine, the food industry, and agriculture. We investigated the ability of an antifreeze protein from the desert beetle Anatolica polita, ApAFP752, to confer cryoprotection …

Othered Ambitions: The Conflation Of Villainy And Homosexuality In 20th Century American Media, Sherard Harrington

Doctoral Dissertations

This work sets out to examine the ways in which homosexuality and villainy have been conflated throughout the 20th Century in American media, and the ways in which that conflation has been reinforced and challenged. My observations about the villainous connotations of homosexuality hold despite the ways in which the boundaries of homosexuality have changed throughout the century. A homosexual is anyone who experiences romantic or amorous affection for someone who presents with the same gender presentation and/or who experiences attraction aversion for those who present with the opposite gender presentation. A villain breaks the law seeking to restructure society …

Rational Design And Synthesis Of Antifreeze-Protein Inspired Polymers For Anti-Icing Coatings And Cryopreservation Applications, Mohamamd Mousazadehkasin

Doctoral Dissertations

Certain organisms living in cold regions have adapted different strategies to survive in harshly cold temperatures. Some of them use freeze-avoiding strategies in which they can prevent freezing by controlling the concentration of sugars (et. sucrose, trehalose) or polyols (glycerol), regulation of the ice nucleator, and dehydration. Other organisms have adapted to this extremely cold condition by producing antifreeze (gly)proteins (AF(G)Ps) which exhibit ice recrystallization inhibition (IRI), thermal hysteresis activity (THA), and dynamic ice crystal shaping. These proteins discovered in Antarctic fish in 1960 for the first time have been reported in bacteria, fungi, insects, and plants. AF(G)Ps and their …

Rna-Seq Analysis Of Transgenic Arabidopsis Thaliana With Conferred Overproduction Of Putrescene By A Mouse Ornithine Decarboxylase Gene, Eric English

Master's Theses and Capstones

Polyamines are a class of low molecular weight, nitrogenous bases that participate in many important functions in plants, from germination to senescence and many steps in between. These molecules have been shown to play key roles in various abiotic and biotic stress responses which makes their biosynthetic pathway a focal point for engineering plants to better adapt to rapidly changing local environments and global climate change. Previous work with plants capable of producing high polyamine titers shows that they have superior stress responses as compared to their wild type counterparts. This study investigated what broader impacts a genetic manipulations to …

Characterization And Knockdown Of Tata-Binding Protein 1 In Toxoplasma Gondii, Malorie R. Nitz

Master's Theses and Capstones

Toxoplasma gondii is a single celled eukaryotic parasite that causes the disease toxoplasmosis, which infects approximately thirty to fifty percent of the world’s population. Current treatments for toxoplasmosis are lacking and immunocompromised individuals are at risk of a reactivation of acute infection. Tight control of transcription initiation is critical for maintaining proper infection for the parasite. TATA-binding proteins (TBPs) are critical transcription factors for recognizing and binding to the TATA-box and other motifs in eukaryotes to recruit the transcription preinitiation complex. Toxoplasma contains two TBPs, TgTBP1 and TgTBP2, but TATA-boxes or other conserved motifs have not yet been identified in …

Research Report: High Tunnel Tomato Fruit Cluster Pruning, Caterina Roman, Rebecca G. Sideman

Faculty Publications

Tomatoes are a high value crop grown worldwide. Indeterminate varieties are commonly grown in high tunnel structures throughout New England for the fresh market. Indeterminate tomato plants often suffer from a phenomenon called ‘June drop’ in which the plant’s first four to five cluster of fruit set perfectly but the subsequent two to three clusters have poor set and plant productivity drops suddenly. While cluster thinning (e.g., reducing the number of fruit allowed to mature per cluster) has been successfully shown to increase fruit size, it has generally not increased marketable yield. We hypothesized that reducing the fruit load by …

Gli3 And P300: Modulating Inflammatory Cytokine Production In Monocytes, Storm Devin Gardner

Master's Theses and Capstones

GLI3 is an important protein traditionally found in the Sonic Hedgehog pathway. It is involved in numerous events that take place during embryogenesis such as the differentiation and patterning of cells in the body. Monocytes are important innate immune cells which infiltrate the site of inflammation when a pathogen invades our body. Gli3 has also been shown to be upregulated in monocytes following pathogen stimulation, suggesting Gli3 could have an important role in mediating the release of inflammatory signals known as cytokines. The histone acetylase protein p300 traditionally acetylates histones to epigenetically modify them to allow DNA unwinding and subsequently …

Uv Sulfite Advanced Reduction Process For Pfos Transformation In Wastewater Treatment, Cassidy Rae Yates

Master's Theses and Capstones

Most nutrients and contaminants within municipal wastewaters are removed through physical, chemical, and biological treatment methods. Per- and polyfluoroalkyl substances (PFAS) are a class of contaminants of emerging concern (CECs) that are concentrated in wastewater treatment facilities (WWTFs) from municipal, industrial, and commercial sources in communities. PFAS are poorly removed in conventional municipal wastewater treatment because these facilities are generally not designed for treatment of low-level CECs. Some PFAS leave WWTFs through aqueous effluent, while others partition to solids and are handled in sludges due to properties based on the degree of fluorination, chain length, and headgroup. As the last …

Tiktok: A New Source Of Labor, Max Oxendine

Comm-entary

In my research paper TikTok as a new source of labor is elaborated upon. The social media platform that originated in 2016 allows you to watch or create videos anywhere from 15 seconds to 3 minutes long. Some content that can be seen or made on TikTok tends to be videos that are entertaining, informative, or in most cases the newest dance trend. In my research paper I wanted to dive deeper into if this new popular app could be a reliable source of labor? Becoming a paid social media influencer does not occur overnight and success is not just …

Is Being A Social Media Influencer A Sustainable Career?, Mya Sanders

Comm-entary

Being a social media influencer in today’s world has its stereotypes: that it is not a real job which one can have for their whole lives, that it does nothing useful for society, or that people get paid to take videos of themselves and nothing more. While that argument has valid points for individual people, I discuss in this paper the idea that being a social media influencer can be a sustainable career path. I mention the positives of the career path: how influencers have the power to change their followers’ minds on a topic, how they can be a …

Pragmatics Paper: The Real Housewives Of New Jersey, Madeline Graf

Comm-entary

Reality television has brought viewers into the lives and homes of many different families across the country. While people question the ‘reality’ aspect of reality TV, the interpersonal conflict amongst families, friends, and loved ones is definitely far from scripted. Shows such as The Real Housewives franchise allow viewers to see many patterns of human communication on their screen, even if they are unaware of it. Using the theories discussed in the Pragmatics of Human Communication by Watzlawick, Beavin and Jackson, this paper analyzes the family systems and interpersonal relationships within The Real Housewives of New Jersey. Applying the concepts …

Shein: How Immaterial Labor Fuels The Capitalist Fast Fashion Industry, Sara Donatello

Comm-entary

This paper highlights the consumption of fast fashion products by consumers as immaterial labor. The industry runs not only on the production of goods, but the consumption and advertising done by influencers and everyday consumers alike. The research explores romantic individualism as a way to advertise products to followers and how the global apparel industry works. Research is supported by surveys completed by SHEIN consumers ages 18-25. The sustainability of the fast fashion industry is also a factor explored in this paper.

Grace Helbig Will Never Be A Hollywood Star, But David Dobrik Will Be, Julia Gomes

Comm-entary

The balance of internet celebrities' careers and the limitations that they are put on due to the pressure of parasocial relationships has changed over time within the world of mainstream media and the internet. In this paper, I explore parasocial relationships and their effects on internet professions. I start by focusing on an early Internet/YouTube star Grace Helbig and discuss how the internet and parasocial relationships affected her career and changed the shape of the internet. I then transition into talking about a newly successful Internet/Youtube star, David Dobrik, and discuss how he faced an opposite journey to Helbig to …

The Bipartisan Media Strategy: How Three Ideologically Different Candidates Found Success, Madeline Graf

Comm-entary

This essay analyzes the social media strategies used by three very different candidates who have all run for presidential office. Using Joshua Meyrowitz’s application of Erving Goffman’s The Presentation of Self in Everyday Life, we can see the ‘middle region’ performances politicians use to seem approachable and relatable to their target audience. With the transition from print media, to the early stages of electronic media, to social media, the barrier between a politician and the public has broken down to the point where the American public has the illusion of a personal connection with these political figures. It is hard …

A Response To Woodstock 99: Peace, Love, And Rage; Recontextualizing Editorial Biases In Nu Metal, Samuel Graff

Comm-entary

Nu metal, the oft-maligned subgenre of heavy music which reached massive commercial heights around the turn of the millennium, has long been a pop cultural punching bag. With recent media trends retrospectively framing past movements along ill-defined identity lines, the 2021 HBO documentary “Woodstock 99: Peace, Love and Rage” takes a close look at the ill-advised late-90s festival and does so by condemning Nu metal as staunchly consumerist, misogynist, and racist. These characteristics are generally held across the few pieces of media scholarship on the genre. In this paper, I analyze and rebuke the documentary and in doing so, provide …

Are Humans An Invasive Species? How The Development Of Our World Has Continuously Encroached On Wildlife, Madeline Graf

Comm-entary

Through the development of our society mankind has adversely impacted the species that existed long before humans did. Humans have effectively become an invasive species, taking over the homes and resources of animals across the globe. People continue to expand into new lands and territories to compensate for an ever-growing population, converting natural land into cities with homes, offices, shopping centers, and more. Through urbanization we are displacing countless species from their natural habitats or forcing them to adapt to a new environment. As our world grew, so did our economies and trade market, creating the issue of global shipping …

A Manufactured Culture: A Look Into How U.S. Imperialism Coerced The Philippine Economy Into A Culture Of Migration, Gio Ramos

Comm-entary

In this research paper, I investigate the origins of labor brokerages in the Philippines. The Philippine economy heavily relies on remittance which is when temporary overseas Filipino workers and emigrants send money back to their families in Philippines. This money is then flushed back into the local economy and keeps it running. Throughout this essay, I find that United States imperialism is a root cause for early labor systems in the archipelago. I analyze historic books and other expert studies on this topic to come to a final conclusion that illuminates my primary research question. How has US imperialism coerced …

Doing Gender With Ink: The Social Construction And Performance Of Gender As A Tattooed Person, Meghan Rose Lewis

Master's Theses and Capstones

Previous research surrounding tattoos and gender has shown that cismen and ciswomen’s tattoos often differ in size, placement, and design, but little research has investigated why these differences persist. Furthermore, studies on tattoos and gender remain limited in scope as they mainly focus on the lived experiences of cisgender men and women. The current study seeks to expand previous research by including a more gender-diverse sample to investigate how the social construction of masculine and feminine tattoos occur, and how participants across the gender spectrum perform gender through tattoos. For this study, I conducted 20 semi-structured in-depth qualitative interviews with …

Understanding The Fate And Transport Of Per- And Polyfluoroalkyl Substances In Wastewater Systems: A New England Perspective, Sydney Kathleen Adams

Master's Theses and Capstones

This thesis explores the story of per- and polyfluoroalkyl substances (PFAS) in New England wastewater systems. PFAS compounds, known for their environmental persistence, toxic nature, and heavy integration into our daily lives, has recently become an infamous topic in environmental engineering due to the discovery of contaminated agricultural lands, water resources, and food systems. In response to these daunting discoveries, regulators have begun looking to reduce point source pollution of PFAS, including that of wastewater systems and facilities. As conduits of PFAS, wastewater systems funnel PFAS from industrial, commercial, and residential sources and emit them into the environment via aqueous …

Welch & Democratic Candidates Lead In Vt Congress Matchups; Majority Want Scott To Run For Governor Again 4/25/2022, Unh Survey Center

All UNH Survey Center Polls

Vermont Congressman Peter Welch is the clear leader in the race for the U.S. Senate seat currently held by retiring Senator Patrick Leahy. State Senate President Pro Tempore Becca Balint, Lieutenant Governor Molly Gray, and State Senator Kesha Ram Hinsdale are closely matched in the Democratic primary for the U.S. House seat being vacated by Welch but all three hold clear advantages over prospective Republican opponent Marcia Horne. Republican Governor Phil Scott has not decided whether to run for re-election, but most Vermonters want him to do so and half think he deserves to be re-elected.

Conspiracy Vs. Science: A Survey Of U.S. Public Beliefs, Lawrence C. Hamilton

Carsey Publications

In this brief, author Lawrence Hamilton reports the results of a nationwide U.S. survey that asked respondents whether they agreed, disagreed, or were unsure about a series of statements that mixed pseudo-science con­spiracy claims with well-established scientific facts.

Around 10 percent of respondents agreed with conspiracy claims that the Earth is flat, NASA faked the Moon landings, or COVID-19 vaccinations implant tracking microchips. For comparison, 58 to 83 percent agreed with statements of basic scientific facts—such as the Earth is billions of years old, or revolves around the Sun. Although agreement with conspiracy claims was low overall, it was significantly …
