Spectroscopic Analysis Of Potential Astromolecules Via Quantum Chemical Quartic Force Fields, Mason Gardner

Honors Theses

Astrochemistry has been substantially aided by computational techniques, particularly through the use of Quartic Force Field (QFF) analysis. Several methods have proven useful at correlating computed spectroscopic data with experimental observations. The F12-TZ QFF correlated well with experimental data for silicon oxide compounds, particularly those potentially involved in development from rocky bodies to planetary masses [27]. Compared to argon matrix experimental data, the vibrational frequencies for the molecules SiO2, SiO3, Si2O3, and Si2O4 become less accurate as the complexity of the molecules increases but should still be predictive of infrared characteristics of silicon oxides as they form clusters in space …

Determination Of Metals In Whey And Vegan Protein Supplements Using Inductively Coupled Plasma Mass Spectrometry, Megan Lofaso

Lc-Ms/Ms Method Development And Analysis Of Tricyclic Antidepressants In Human Plasma, Shahbaz Gul

Honors Theses

Depression has become one of the most prominent problems in society, disrupting both personal and social lives. Tricyclic antidepressants (TCAs) were first developed in the 1950’s and became some of the leading anti-depressant medications on the market later that decade. Today, newer anti-depressants have risen to the forefront, being safer and having a lower side-effect probability. Nonetheless, TCAs continue to be prescribed for severe depression, especially in cases where the newer anti-depressants have failed. However, TCAs are still highly potent, the toxicity associated with these compounds cannot be ignored. They have considerable cardiovascular and neurological toxicity, and in the event …

Duality In Digital Discourse: The History And Future Of The American Public Forum, Nicholas Weaver

Honors Theses

From the onset of the republic, the liberty to speak freely and debate openly has stood guard and helped preserve all other American rights. While this concept has endured, the means by which it exists in society has changed immensely. As the public forum has evolved to fit the modern needs of the citizenry, political discourse has become less a defense against tyranny and more a chaotic space of conflicting opinions.

In the United States, privately-owned social media companies have grown at an unprecedented rate, yet lawmakers have been slow to exercise any authority to regulate these corporations. For public …

A Weighted Version Of Erdős-Kac Theorem, Unique Subedi

Honors Theses

Let $\omega(n)$ denote the number of distinct prime factors of a natural number $n$. A celebrated result of Erd{\H o}s and Kac states that $\omega(n)$ as a Gaussian distribution. In this thesis, we establish a weighted version of Erd{\H o}s-Kac Theorem. Specifically, we show that the Gaussian limiting distribution is preserved, but shifted, when $\omega(n)$ is weighted by the $k-$fold divisor function $\tau_k(n)$. We establish this result by computing all positive integral moments of $\omega(n)$ weighted by $\tau_k(n)$.

We also provide a proof of the classical identity of $\zeta(2n)$ for $n \in \mathbb{N}$ using Dirichlet's kernel.

Synthesis Of A Dd-Π-Aa Organic Dye For Dye-Sensitized Solar Cells, Hope Lovell

Honors Theses

This project investigates the synthesis of a DD-π-AA (dual donor/dual acceptor) organic dye as a potential sensitizer for dye-sensitized solar cells (DSCs). The design of this dye was based off previous research that found dual donor/dual acceptor dyes exhibited promising results when used in a DSC. The donor groups, acceptor groups, and π-bridge were chosen for their stability, ability to absorb in the near-infrared (NIR) region, and intramolecular charge transfer (ICT) abilities.

While many components of the dye were synthesized, the final stages of the synthetic scheme were not completed due to the loss of time from COVID-19. Had the …

Soil Inhomogeneity Effects On Seismic Wind Noise, Bipin Koirala

Honors Theses

Wind causes local pressure fluctuations over the ground. The pressure waves couples with the ground and transmits into the ground as seismic waves. The seismic wave, in turn, causes ground motion. Naderyan et al. [9] developed a prediction of the ground displacements spectra from the measured ground properties and predicted pressure and shear stress at the ground surface. Naderyan modeled the ground as a linearly elastic half space bounded by an infinite plane on one side. The quasi-static model for predicting displacement components in the ground is effective for the vertical component of the displacement response, but the model significantly …

Incorporating Demographic Structure And Variable Interaction Types Into Community Assembly Models, Akhil Reddy Alasandagutti, Nayan Chawla

Honors Theses

Theoretical studies of ecological food webs have allowed ecologists to remove the constraints of specific location and timescales from their study of ecological communities; food webs are generally complex and thus empirical study is difficult. Further, this theoretical approach allows ecologists to compare ecological processes and outcomes across any possible food web structures. However, these simulated communities are only as useful as the model from which they were constructed. Modifying existing considerations in these models, and generating new ones, are the jobs of theoretical ecologists that seek to achieve the shared goal of a majority of simulations: representation of real …

Art And Aids: Viral Strategies For Visibility, Stephen Baylor Pillow

Honors Theses

“Art & AIDS: Viral Strategies for Visibility” examines the complex relationships between social stigma, healthcare, homophobia, and mortality, and how these impacted the lives of Western artists and manifested in their works. Most of the art discussed in this thesis was produced during the height of the AIDS crisis (late-1980s to mid-1990s). During this period, gay artists and their allies employed new strategies in their work to inspire activism, and convey intense emotions –– predominantly frustration, grief, and anxiety –– associated with HIV/AIDS. In the U.S., the inaction of the Reagan administration was largely due to widespread homophobia kindled by …

The Effects Of Cochlear Implantation And Educational Audiology Services On Language Skills: A Case Study, Madison Josey

Honors Theses

Purpose

Hearing loss can affect many aspects of a child’s life, particularly their language abilities and academic performance. Literature shows that children with hearing loss are more likely to have language deficits compared to their hearing peers (Tomblin et al., 2015). The degree to which language skills are affected has been shown to correlate with various factors, such as age of identification, hearing levels, and amount of speech and language intervention (Delage & Tuller, 2020; Shojaei et al., 2016). The aim of this research study was to assess how cochlear implantation and speech-language intervention affects the language skills and academic …

The Effects Of Fictional Literature On Real-World Perceptions Of Students, Dylan Dowty

Honors Theses

The ways in which fiction affect the perceptions of high school students’ realities are many, and they vary widely depending on the book read. While lessons can be learned from every fictional book, certain types of books are more beneficial and relevant for students. Young adult literature, while often overlooked, is a significant source of students’ perspective shifts and metacognition. Every book has a lesson that it can teach students, but contemporary young adult literature deserves to be taught in schools alongside the classics in order for students to make personal connections with the texts they read and take an …

Parametric Design Of Flywheel For An Electric Punch Press, Prashant Dhakal

Honors Theses

Almost all designs start with a design requirement. These may be weight, volume, clearance, and even custom calculations. Finding a solution that meets these requirements often involves tedious and time-consuming iterations. Once the solution has been found, the design must be optimized to find the best possible solution. Finding the ‘best possible design’ requires substantial time and effort dedicated to iterating and analyzing the potential model solutions. This is where Parametric design comes into play. The Parametric design aids in specifying the key parameters of the design and makes changes interactively, with the model updating automatically. The purpose of this …

Synthesis Of Halogenated Glyoximes, Nickie Tiwari

Honors Theses

Dr. Huang is a chemical engineering professor at the University of Alabama. He is interested in using alpha-Halogenated glyoximes to better understand impurity incorporation of organic additives. Various alpha-Halogenated glyoximes are being synthesized for his study. In this project, bromodimethylglyoxime is being synthesized. This is a two-step reaction. The first reaction converts diacetlymonoxime to bromodimethylglyoxalmonoxime through bromination. The product is then reacted with hydroxylammonium chloride to form bromodimethylglyoxime. Ultimately, there has been success in forming bromodimethylglyoxalmonoxime. For this reaction, solvent ratios of methanol must be proportional to literature values. However, there have been difficulties in converting bromomonoxime to bromodimethylglyoxime. There …

Describing The Gut Microbiome Of Two Freshwater Mussel Species Within The Tennessee River Basin, Eloise Cotten

Honors Theses

Freshwater mussels are important bioindicators of aquatic environmental quality, yet little is known about the composition of their gut microbiome or how it varies between different locations and mussel species. In this study, two species of mussels were collected from three sites located in two rivers, the Duck River and the Paint Rock River of the Tennessee River Basin. The gut microbiome of each mussel was characterized by 16S rRNA gene sequencing. Gut microbial communities were primarily composed of members of the Planctomycetes, Cyanobacteria, and Proteobacteria, which along with six other phyla accounted for nearly 90% of the sequences. Dominant …

Exploring Manifoldlike Causal Sets And Their Dimensions, Santosh Bhandari

Honors Theses

Causal Set Theory is an approach to quantum gravity that tries to replace the continuum spacetime structure of general relativity with the spacetime that has the property of discreteness and causality. From the standpoint of causal set theory, our spacetime is made up of discrete points that are causally related to one another. A causal set is said to be manifoldlike if it can be faithfully embedded in a Lorentzian manifold. In this thesis, some of the fundamental properties of causal sets are discussed. The first chapter is devoted to the historical background of quantum gravity with a discussion of …
