Optimization Of A Fluidized Bed Reactor For The Production Of Styrene From Ethylbenzene, Gregory Espenan

Honors Theses

In order to optimize Unit 500, a styrene production plant, the Net Present Value (NPV) was used as the objective function to ensure every optimization strategy had a positive economic effect. To optimize a chemical plant, it is important to note efficiency, economics, product specifications, and production requirements. The goal of this project was to make changes to the base case of Unit 500 to minimize the cost to produce styrene for an upstream unit. PRO/II was used to simulate various points in different unit operations throughout the process. The NPV was measured after each unit operation was simulated to …

Animal sickness behavior is an important component of disease ecology and is essential to understanding wildlife diseases and how and where animals allocate resources for survival. This study examines sickness behaviors, the extent of conjunctivitis, and the presence of an antibody response in relation to a Mycoplasma gallisepticum (MG) respiratory infection in American goldfinches. We conducted an experimental infection of American goldfinches and recorded behavior videos, and collected blood samples, throat swabs, eye swelling, and mass data at multiple time points throughout the experiment. An ELISA-serum assay was run after the conclusion of the study to identify the presence of …

America’S History Of Health Disparities: How Does This Affect The Future Of Healthcare In Mississippi?, Zuri O. Dixon Omere, Jazmin King

Honors Theses

America’s healthcare system runs rampant with healthcare inequalities that have an alarming effect on minorities and people of color. In order for people of color and marginalized groups to receive proper care and treatment, more attention needs to be brought to these inequalities. For example, Covid-19 reflected the health inequalities that are present in this country; minorities were more likely to become hospitalized due to Covid-19 than other non-minorities. In addition, minorities in women’s health, specifically black women, have been affected in various ways that are related to the inequalities in medicine like dying during childbirth and improper care. This …

Design Of An Implanted Vascular Access Device With A Mechanical Septum, Mallory Ann Moffett, Katherine Rose O'Quinn

Honors Theses

As populations continue to age, their need for medical care continues to rise. This is seen by the large need for implanted vascular devices (IVADs). IVADs are essential for individuals with poor venous access and patients requiring long-term venous delivered drugs. This document will explore the existing IVADs, where they fall short, and where our device, the IrisPort system, works to solve the unmet needs of patients. The IrisPort system is a needle-less port system that allows for repeated venous access without the use of a non-coring needle. Prior art searches have shown that the IrisPort is a novel solution …

Development And Prototyping Of Motion Capture Hand Cluster Using 3d Printing, Griffin Adcock

Honors Theses

Motion capture is being used to analyze the pitching motion of Mississippi State’s softball pitchers. The motion capture requires that the athletes be covered in clusters of reflective markers for the cameras to track their movement. The current cluster responsible for tracking the pitching hand of a softball player is continually being destroyed as the outer edge of the pitcher’s hand and the cluster contact her thigh. A new cluster was designed to only cover a small portion of the back of the hand, which eliminated the risk of breaking the cluster during pitching. The hand cluster was produced using …

Applying Mci-062, A Novel Pan-Ras Inhibitor, To Treat Kras-Mutant Lung Cancer, Richard Fu

Honors Theses

RAS is a prevalent oncogene that is mutated in 27% of human cancers. Gain-of-function RAS mutations activate multiple downstream pathways, including the RAS-RAF-MEK-ERK and PI3K/AKT/mTOR pathways, which are critical in tumorigenesis and cancer cell proliferation. RAS proteins such as KRAS, a member of the RAS protein family, and their downstream effectors are attractive targets for cancer therapy since their mutations act as frequent drivers in lung, colorectal, and pancreatic cancers. However, RAS proteins have relatively smooth surfaces that lack traditional binding pockets, making inhibitors specific to RAS difficult to create. Recently, a novel small molecule pan-RAS inhibitor named MCI-062 was …

Bee Pluribus Unum: Vergil As An Imperial Advisor, Oleander Reagan-Artemis

Honors Theses

All three of Vergil’s major works received patronage, although somewhat indirectly, by Augustus, the first Roman emperor, and they have been an integral aspect of education since they were given to the public. Research going back hundreds of years, from John Wesley of the late 1700s to the contemporary Peter White, has sought to address the finer details of the relationship between Augustus and Vergil, focusing heavily on Vergil’s attitude towards Augustus and the new imperial rule. In this paper, I will add to this controversy-steeped conversation from the perspective of an educator, highlighting the possibility that Vergil was a …

An Argument For Sensuous Revolution And Its Manifestation In The Food System, Anna Smith

Honors Theses

In this food system, we witness issues such as health disparities, social injustice, and environmental injustice, which all flow within one another. When seeking to address such issues it is essential to recognize their inherent interconnectedness and root causes; otherwise, intended solutions can perpetuate the issues they aim to solve when they do not encompass full-seeing. The greatest barrier to full-seeing is disconnection with experience, which occurs when what we are experiencing is obscured by static conceptions. This inhibition of holistic understanding, when occurring through such limited perspectives, makes solving issues such as health disparities, social injustice, and environmental injustice …

A Seminar For Student Leaders To Engage And Retain Members In Student-Led Organizations, Luke Mcpherson

Honors Theses

The challenge of attracting and maintaining members in student-led organizations (SLO) inspired this thesis. Current research literature was used to create a presentation for student leaders. The presentation applied marketing principles as well as best practices suggested by the research. Interviews with four student leaders and two administrators involved in student activities were conducted to interact with the research. Their insights suggested that the strongest factor in attracting students was social, whether personal invitation or a sense of belonging to the group. The strongest deterrent to participation was a perception that the benefits did not outweigh time commitments to school …

Theoretical Studies Of Benzoquinone Reactivity In Acidic And Basic Environments, Natali Majoras

Honors Theses

Quinones are a class of organic compounds containing a six-membered unsaturated ring with two carbonyl groups. They are biologically relevant mostly due to their ability to participate in redox reactions. Prior experiments in our lab showed that quinones can induce protein modifications that are pH dependent. In an acidic environment the modifications were less significant than in a basic environment. Previous computational studies have also been carried out to model, in neutral solutions, the reaction between various quinones and various amines. Various amine groups are used as a model for the amino group of lysine to represent protein modification. The …

Constructing The “Obesity Epidemic:” A Chronology Of The Pathologizing And Enfreakment Of Fatness, Brooklynn Smith

Honors Theses

The “obesity epidemic” is framed by medicine and media as a public health crisis that urgently demands medical intervention and policy. Despite this common narrative, the cultural and scientific dimensions, as well as the historical roots of the “obesity epidemic,” have been subject to much less scrutiny than necessary. Part of this inadequate scrutiny is due to the pervasive pathologizing of fatness that has roots back in 18^th- and 19^th-century ideals of normative bodies. While the contemporary American medical system holds the “obesity epidemic” as objective truth, scholars both within and outside of medicine have challenged …

A Cold War On The Dark Knight: Batman And American Culture 1939-1975, Angelica Cantrell

Honors Theses

In 1930, Batman fought the prevailing fears of urban America. With the addition of Robin in 1940, the comics changed to appeal to children and continued to follow the cultural trends of America during World War II and into the Cold War. Fear and paranoia during the Cold War influenced American culture and domestic policy. Anticommunism was ingrained in American social structure and initiated efforts at social containment in the 1950s. American culture shifted to emphasize morality and domesticity, and many Americans actively sought to protect traditional Christian values in their society.

Among the rising concerns, Americans became increasingly worried …

Lost Memories, Lost Colonies, Emma C. Smith

Honors Theses

The Roanoke Colony was the first English colony in America. The colonists were abandonded by the Governor shortly after the colony was established. In public memory, the fate of the colony is highly debated and has since become an American founding myth. As a result of the contested fate, the story of Roanoke has since become a blank slate upon which other legends can evolve. These legends become a window for historians into the insecurities of those who created them. This paper discusses why the English wanted to establish a colony, the popularization of Pocahontas, the history of marriages between …

Problematic Advocacy And Victorian Public Health In Gatherings From Graveyards By Dr. George A. Walker, Olivia Ladner

Honors Theses

This thesis focuses on the problematic advocacy of Dr. George A. Walker in his public health pamphlet, Gatherings from Graveyards. In his work, Walker calls for the removal of urban cemeteries from within London and other cities in Great Britain due to concerns about public health safety. He cites miasmatic theory as the reason for the spread of disease from rotting corpses and unkept cemeteries in the British metropolis. Though he blames Parliament for the state of urban cemeteries, he continuously cites poor communities and neighborhoods as the sole sources of disease and does not conduct investigations into the …

Effect Of Coastal Environments On The Post Mortem Interval Of A Pig Carrion: Implications For Human Decomposition, Morgan Hough

Honors Theses

Forensic taphonomy involves the use of forensic techniques to determine the post mortem interval of a corpse. There are many factors that are known to influence the rate of decomposition, such as the temperature, season, soil type, moisture potential of the soil, and presence of insects or other decomposers. Previous studies in this field have focused primarily on decomposition patterns in mountainous environments in terms of terrestrial habitats or strictly aquatic environments, leaving this particular aspect of coastal settings to be unexplored.

To study these effects, the superior portion of a female pig was buried in sandy soil in mid-October …

Song Lyrics In The Hobbit: What They Tell Us, Thalia Mcinnis-Trussell

Honors Theses

Tolkien is argued by many to be the author of the century, a legend, and the kickstart to the fantasy genre. Despite these claims, there is very little research done about the song lyrics in his works, especially not in The Hobbit. I have analyzed how the song lyrics show the relationship with time and history of each race—dwarves, elves, hobbits, and goblins—and how their values are shown through their lyrics.

Keywords: Tolkien, The Hobbit, Lord of the Rings, Songs, Music, Hobbits, Dwarves, Elves, Goblins, Values

Movement As A Way Of Knowing Earth: An Ecosomatic Approach To Developing Movement Choices, Brittany Tolbert

Honors Theses

The senior choreographic project The Spirit of Gaia aims to not only build awareness for individuals about the impact humans have on the climate crisis but also to inspire change in the way in which humans utilize movement practices for the benefit of Earth. As a creative process based in somatic exploration and a performance contingent on a live audience, The Spirit of Gaia exists as a living moment of dance. Acknowledging the power movement has to be the progenitor of a larger environmental consciousness and an eco-friendly change on the individual level, the dance acts as a means of …

Studying Suspended Sediment Concentrations In The South Chickamauga Creek Of Chattanooga, Tn Using Satellite Imagery, Digital Image Processing, And Numeric Modeling, Abigail Faxon

Honors Theses

In recent years, Hamilton County, TN has experienced extensive urban growth. According to US Census data, Hamilton County welcomed more than 33,000 new residents in the last decade. There is increased concern about the environmental sustainability of Chattanooga’s urban growth because significant impervious surface development has taken place along the South Chickamauga Creek. This leaves the creek subject to increased urban runoff, which often carries sediments with different municipal pollutants. Thus, monitoring turbidity in the stream water is important to determine the sustainability of urban development in Chattanooga, TN. In this research, we have compared the viability of using different …

Media Sexualization And Its Impact On College Aged Women, Madelyn Moncrief

Honors Theses

Social and traditional media are often studied in relation to women’s perceptions of sex. However, they are often studied separately instead of together, missing the overall connection of media on attitudes. The purpose of this study was to investigate the relationship between media consumption, specifically social media and television, and college-aged women's levels of internalized sexualization. The findings of this study found a significant positive correlation between time spent consuming romanced-based reality television and romantic comedies and higher levels of internalized sexualization in college-aged women. This study also found there to be a significant positive correlation between college women’s usage …

Social Change Through Rhetorical Action: Case Studies Of Two Tennessee Women In The Archives, Dalton Burks

Honors Theses

In conversations about social change and activism, the American South is rarely represented as a place where such change occurs. However, this analysis will focus on two unlikely activists who used their writing and voices to advocate for change on a local scale in their individual communities. These activists are Emma Bell Miles, an artist, naturalist, and creative writer from Chattanooga, Tennessee who wrote a persuasive column in the Chattanooga News on feminism and naturalism, and Mary Cunningham, a local librarian and mother from McMinnville, Tennessee who created the Magness Library and Community House. This thesis argues that Miles and …

Speech Acts As Contingent Encounters: Realizing Agency In Contaminated Worlds, Zachary Cross

Honors Theses

Agency is realized in the act of speaking, an act which is always contingent on a collaborative process that transforms all parties involved. We think and act with one another and our concepts, there is no act of speech prior to encounter. In this paper I explore different ways which language shapes our thinking and play with those structures to use them as models for realizing agency. This exploration became personal insofar as exploring ways of thinking transformed my own sense of agency in the speech act. The completion of this paper is thus essential to its conclusion.

The Effects Of Dissolved And Suspended Solids On Freshwater Meiofauna, Jessica Cline

Honors Theses

Meiofauna include small-sized animals (< 1mm) distributed in all aquatic ecosystems on Earth, where they play fundamental trophic and ecological roles. The biodiversity of marine meiofauna and its links with anthropogenic activities is routinely investigated, however, freshwater communities are less known. This is particularly true for the Southeastern United States, which is greatly investigated and elected a hotspot of biodiversity for larger species but very little is known about the meiofauna. The purpose of this research is to reveal the biodiversity of meiofauna from the Tennessee River and test for potential correlations with anthropogenic activities. As a proxy for pollution, dissolved and suspended solids were considered in this study. The research hypothesis is that meiofaunal biodiversity would be affected by possible changes of dissolved and suspended solids in the water column. Possible mechanisms causing biodiversity shifts could be ascribed to osmotic stresses of animals to cope with variation in dissolved solids or, more indirectly, because different sunlight penetration caused by suspended solids would affect primary production. To test the hypothesis, water samples were collected from nine stations located along the Tennessee River in Hamilton County. Each station was visited three times, and, during each visit, environmental parameters (including dissolved and suspended solids) were measured. Meiofauna biodiversity (estimated as richness, community composition, and phylogenetic diversity) was revealed using a metagenomic approach. Statistical analyses were applied to test for possible correlations between the biodiversity estimates and the measured environmental parameters. Results show a high biodiversity of meiofauna with more than 200 amplicon-sequence variants distributed across 10 metazoan phyla. Environmental conditions are highly variable among stations and statistical analyses show that while both dissolved solids (TDS) and turbidity (suspended solids, NTU) did not significantly affect meiofauna biodiversity in the collected samples, various other water, and sediment metrics were found to be significant predictors of meiofauna biodiversity. In conclusion, the results of this project not only reveal for the first time the meiofauna biodiversity from the Tennessee River, but also suggest that meiofauna could be used as bioindicators for several anthropogenic activities in freshwater ecosystems.

Synthesis And Characterization Of Organometallic Complexes For Biological Imaging, Emily Stumbo

Honors Theses

Luminescent transition metal complexes are of interest for biological imaging applications due to their unique photophysical properties including large Stokes shift, long fluorescence lifetimes, and tunable emission. Altering ligand structure is a useful way to manipulate the charge transfer (CT) and mixed character states that give these complexes their photophysical properties. A series of organometallic complexes containing ligands with externally facing nitrogens has been prepared and synthesized. Complexes of the form Pt (II)(tbbpy)(C2-py), Re(CO)3(N^N), Ir(C^N)2(N^N), and Ir(C^N)2(N^O) have been studied for their potential application as biological imaging agents. The goal of this project is to compare the properties of these …

Habitat Preference Of F. Notatus And F. Olivaceus From A Reversed Hybrid Zone, Elizabeth Hart Williams

Honors Theses

Understanding the mechanisms driving habitat preference throughout an organism’s life opens doors to the further understanding of the origins of diversity. Two species of minnow, Fundulus notatus and Fundulus olivaceus, are ideal for ecological research on habitat preference. Ordinarily, F. notatus and F. olivaceus display habitat preferences of downstream and upstream, respectively, with minimal coexistence at confluences. However, in some drainages, these preferences are flipped, like those in the Tombigbee River basin. Members of both species were collected from the Tombigbee River, tagged with species and sex specific colored elastomer marks, and placed in either a homogeneous control or …

Covid-19 Vaccine Hesitancy: Examining The Relationship Between Perceptions Of Covid-19 Vaccine Safety And Intention To Receive It Among African Americans In Mississippi, Tija L. Johnson

Honors Theses

In March of 2020, the World Health Organization declared a global pandemic due to the ongoing spread of SARS-CoV-2, the causative agent of COVID-19 disease. While scientific developers were seeking to understand the biochemical mechanism of SARS-CoV-2, political and public health leaders implemented non-pharmaceutical interventions, such as social distancing measures, to reduce the transmission of COVID-19. As the world began to adjust to the new realities, the race to create an effective vaccine was on. With the later development of the COVID-19 vaccine, receptiveness to the vaccine across the world varied, and in the United States, vaccine hesitancy was an …
