One-Pot Synthesis Of Disubstituted Primary Amines From Nitriles Via Grignard Addition And Metal-Alcohol Reduction, Joshua Peltan

Honors Theses

The process of developing a working base case procedure for a novel one-pot-two-step synthesis of primary amines from Grignard reagents, nitriles, sodium metal or alkali metal loaded silica gel, and alcohol is described. Initial steps towards applying the process broadly are detailed. The process has the potential to be an affordable, convenient, safer, greener, and more accessible alternative to exiting methods of accomplishing the same transformation. The reaction scheme has been proven to provide yields and purity comparable to existing methods for certain pairs of substrates; however, its utility as a general-purpose method for transforming arbitrary pairs of Grignard reagent …

Multi-Scale, Class-Generic, Privacy-Preserving Video, Zhixiang Zhang, Thomas Cilloni, Charles Walter, Charles Fleming

Faculty and Student Publications

In recent years, high-performance video recording devices have become ubiquitous, posing an unprecedented challenge to preserving personal privacy. As a result, privacy-preserving video systems have been receiving increased attention. In this paper, we present a novel privacy-preserving video algorithm that uses semantic segmentation to identify regions of interest, which are then anonymized with an adaptive blurring algorithm. This algorithm addresses two of the most important shortcomings of existing solutions: it is multi-scale, meaning it can identify and uniformly anonymize objects of different scales in the same image, and it is class-generic, so it can be used to anonymize any class …

Effects Of Crowding Agents On I-Motif Dna, Hayden Brines

Honors Theses

Deoxyribonucleic acid (DNA) is a well-known double stranded, helical, biological molecule. In addition to its more commonly known structure, DNA can also form more complicated structures like G-quadruplexes and i-motifs (iM). The iMs are formed by cytosine rich DNA and are a four stranded structure that is typically looped around itself. The iM formation is typically pH-dependent and is favored in more acidic conditions; the pKa value is approximately 6.5. This pKa value allows for potential in vivo formation, since the cells have a pH of approximately 7.3. Due to this, iMs are thought to be powerful, innovative molecules for …

Characterization Of Mechanical Responses Of Helical Antenna For Satellite Communications, Scott Chumley

Honors Theses

The purpose of this work was to identify and analyze the vibrational modes of a helical structure to model the vibrational characteristics of an L-band helical antenna for satellite communications. This project focused on the vibrational modes between 1 and 50 Hz. Using COMSOL Multiphysics finite element modeling of helices were performed to predict mode shapes and frequencies to compare with both continuous wave (CW) and impulsive measurements. In the initial phase of the experimental work, five helical samples were constructed and evaluated. In the second phase of the study, one sample was chosen for more detailed quantitative measurements. In …

Covalent Modification Of Genetically Engineered Polymers With Bodipy Fluorophores, Emilie Smith

Honors Theses

Osteoarthritis and other debilitating diseases cause chronic pain that is difficult to manage. Nonsteroidal Anti-inflammatory Drugs (NSAIDs) are the current standard of treatment for many long-term pain management, but there are potential systemic effects when using NSAIDs long-term. Therefore, it isnecessary to have an alternative option for NSAID delivery that doesn’t include these systemic effects. Hydrogels can be that alternative option. Hydrogels’ distinct characteristics allow them to be viable in the body, degrade under unique conditions, and be modified through many different chemistries. Additionally, hydrogels can be engineered and their properties optimized for the use as a drug depot inside …

Potential For Democratization In Ethiopia, Abby Sonnier

Honors Theses

The United States is losing the competition for global power to China, especially on the African continent. This thesis aims to analyze opportunities for the United States to take advantage of China’s withdrawal from Ethiopia in order to develop relations with the quickly growing country and influence the country toward democratization. This author found that while democracy is not likely, through increasing relations with Ethiopia’s prime minister, the United States has an opportunity to push for increased individual freedoms for Ethiopians. The author relied on open-source information and strategic analytic techniques often employed by the U.S. intelligence community.

The Effects Of Disclosure On Perceptions Of Different Overt Stuttering Severity Levels, Katelyn Geringswald

Honors Theses

This study measured perceptions of a 17-year-old adolescent male who stutters, relative to select speech skills and personality characteristics, as a function of self-disclosure at various overt severity levels. 983 participants were assigned one of the four conditions, including (1) a no-disclosure control group, (2) mild stuttering severity self-disclosure, (3) moderate stuttering severity self-disclosure, and (4) severe stuttering severity self-disclosure. Participants assigned to the control condition viewed only a primary video stimulus of a 17-year-old adolescent who stutters. Participants assigned to one of the three experimental conditions (mild, moderate, or severe severity disclosure) watched a brief self-disclosure statement, followed by …

The Role Of Automotive Value Chains In The Development Patterns Of Mississippi, Mitchell Palmertree

Honors Theses

This thesis investigates the automotive industry within Mississippi through a Global Value Chain lens. Through interviews conducted with economic developers affiliated with Nissan and Toyota’s recruitment, this thesis highlights the effect these final assembly plants on local economic development and the role these economic developers play in their recruitment. The automobile industry within Mississippi behaves much like the automobile industry elsewhere within the world as they tend to locate near final markets, drive the co-location of suppliers, and remain long-lived institutions in the community. This thesis also illuminates the role of state and local actors in recruiting the automotive industry. …

The Politics Of Water Resource Management: State-Guided Framing Of China’S South To North Water Diversion Project And Its Impact On Citizen Perception, Mary Barlow

Honors Theses

Due to China’s geographic and human-exacerbated water scarcity, government leaders have turned to the South to North Water Diversion Project (SNWDP) in order to ensure a reliable source of water for the country’s increasingly parched Northern cities and townships. This thesis examines this inter-basin water transfer project (soon to be the world’s largest) through the lens of how government actors have framed the project. This official framing analysis is presented in tandem with citizen perceptions observed through online commentary in order to evaluate how effective such framing has been. Through such analysis, this research observes a pattern of nationalism and …

Purification Of Pcbp2 And Its Effect On The Formation Of Dna I-Motifs And Secondary Structures, Nathan Redden

Honors Theses

Several secondary, non-B forms of DNA are associated with the promoter regions of many oncogenes, including the intensely studied c-MYC gene that codes for a transcription factor. Two such secondary structures, G-quadruplexes, and i-motifs, have become topics of interest due to their prevalence within oncogenic promoters, as well as their potential accessibility for drug targeting. B-form DNA can adopt alternative structures under certain conditions. These alternative structures are favored when there is an asymmetric distribution of guanosine and cytosine on complimentary DNA strands. The strand rich in guanosine is able to form a quadruple stranded DNA complex termed a G-quadruplex. …

The Great Equalizer Or A Modern Iteration Of Historical Inequality: Artificial Intelligence In Latin America, Santana Amaker

Honors Theses

In recent years, governments across Latin America have taken steps to foster the development and implementation of artificial intelligence causing an expansion of the use of AI in the region. For instance, countries like Colombia and Argentina are using AI in their judicial systems. Superficially, the allure of AI in the judicial system stems from the thought that AI is an impartial entity that will pass fair and unbiased judgement. However, just like the programmers responsible for creating AI, algorithms used in AI system can be biased. The reason being AI is often trained to make predictions or decisions based …

Analysis Of Multigenerational Behavioral Effects Of Dietary Benzo[A]Pyrene Exposure In Adult Zebrafish, Mary Beth Gillespie

Honors Theses

Benzo[a]pyrene (BaP) is a polycyclic aromatic hydrocarbon that is linked to negative reproductive and developmental effects in humans and animals. Because BaP is carcinogenic, and its continued presence in the environment allows it to be inhaled and ingested, better understanding of the effects of BaP is needed. To determine the behavioral effects of BaP exposure, zebrafish were used as a model. Wild-type zebrafish (5D) underwent two separate 21-day dietary exposures to 2.5 and 25 μg BaP/g fish to compare how BaP exposure affects locomotor activity. Following the dietary exposure, fish were mated to obtain and raise the F1 generation to …

Fakes, Forgeries, And Value Perception, Pearson Moore

Honors Theses

Fakes and forgeries generate a false sense of value in the art market that changes the perception of authentic works. Understanding the difference between a fake and a forgery is essential for explaining the schemes of deceivers who have fooled the art market into believing their work is of grandiose value and prestige. The creation of a forged piece or fake provenance documents requires immense artistic skill and a talent for breaking the rules. Examining famous figures and the criminal cases against them is a great way to work backwards from their “successes,” tracing the alleged origins of the piece’s …

A City Divided: A Gis-Informed Study Of Urban Planning In Amman, Jordan, Ella Lawson

Honors Theses

Amman, the capital of Jordan, faces an impending infrastructure crisis. The city is plagued by water shortages, a lack of affordable housing, extreme traffic congestion, and dwindling open space. Over the past seventy-five years, several urban planning commissions have attempted to address these issues through policy change and other municipal directives. These plans help illustrate the different forces at play in constructing the city—whether they be the residents themselves, city officials, or international consultants. All the plans use neighborhoods as a primary metric for measuring need and organizing development. Likewise, all the plans focus on the importance of green and …

Applications Of Sodium Azide In The Synthesis Of Tetrazines And Hydrolysis Reactions, My Le

Honors Theses

The inverse electron demand Diels−Alder cycloadditions of heterocyclic azadienes have provided a robust methodology for synthesizing highly substituted and functionalized heterocycles. It is widely used in organic synthesis and the pharmaceutical industry in the divergent construction of screening libraries and bioorthogonal conjugation. Each heterocyclic azadiene was found to possess a unique reactivity toward different classes of dienophiles, display predictable modes of cycloaddition, and exhibit substantial substituent electronic effects impacting their intrinsic reactivity and cycloaddition regioselectivity. Synthesis of 1,2,4,5-tetrazine has been reported in the literature since the late 19th century, showing scientists' tremendous interest in its application.

Herein we attempt to …
