Mechanochemical Synthesis Of Fuels From Sustainable Sources Utilizing Solid Catalysts, Jacob Todd

Electronic Theses and Dissertations

Mechanochemistry requires less solvents which results in less waste generation. The question becomes can we apply mechanochemistry to current chemical reactions and reduce the generation of waste. This process can be simple or can be very extensive resulting in the generation of large amounts of waste and very little product. A significant advantage of mechanochemistry is the reduced need for solvents that would be common place for reactions. Mechanochemistry transfers energy to reagents via impacts from milling media. Energy can be transferred to the reagents no matter their state-of-matter. Much of the current studies in mechanochemistry today are done using …

The Effect Of Parental Population Density On Offspring Immune Function, Dana Davis

Electronic Theses and Dissertations

It is well known that an individual's environment, genetic code, and gene by environment interactions have an effect on its overall phenotype. However, there is a growing body of work that shows that parents can have an effect on their offspring's phenotype beyond the inherited genetic code. Studies have shown that parents may affect their offspring through physiological mechanisms such as egg provisioning and epigenetic effects and through behavioral mechanisms such as maternal care. In many of these cases, the parental effect is triggered by an environmental cue. Previous work has shown that density can impact immune function and cuticle …

A Correlational Study Of Emotional Intelligence And Language Style Matching, Deprise M. Depass

Honors Undergraduate Theses

ABSTRACT

Individuals subconsciously convey emotions through language. The present study investigates the relationship between emotional intelligence (EQ) and language style matching (LSM). Emotional intelligence involves the ability to regulate, maintain, and express one’s emotions and to perceive the emotion of others. LSM involves the phenomenon that when individuals talk they tend to mimic each other’s word usage (Neiderhoffer & Pennebaker, 2002). The hypothesis of the present study is that individuals who are emotionally intelligent subconsciously match their language to their communication partner. Ten participants from the University of Central Florida’s Psychology Department were given an emotional intelligence test. The participants …

Understanding The Dynamics Of Peer Review And Its Impact On Revision, Julie Kopp

Electronic Theses and Dissertations

Research in writing studies has focused on what happens as students, and often their teachers, talk about student writing. This line of inquiry has identified several strategies for productive peer interactions, including spontaneous talk (Danis; Dipardo and Freedman; Johnson, The New Frontier; Bruffee; Lam), a flexible environment (Dipardo & Freedman; Johnson, "Friendly Persuasion"), positive rapport (Rish; Thompson; Wolfe), feedback and support (Barron; Covill; Flynn; Grimm; Lam; Yucel, Bird, Young, and Blanksby; Zhu), and reflection (Yucel, Bird, Young, and Blanksby). However, research invested in understanding the extent to which such interactions result in better revisions or make students better writers has …

Once Upon A Gender Role:Re-Envisioning The Strength Of Females In Fairy Tales, Itzel E. Garduno-Jaramillo

Honors Undergraduate Theses

Education constantly promotes equality and diversity, however, if the literature we read our students is not doing so, is education doing its job? This question extends as far as females versus males and in fact, this thesis further pursued this issue by taking a look into common fairy tales that have been popularized in modern society that contain stereotypical gender roles and qualities of females that we try to steer away from yet have not.

After doing research into fairy tales and then analyzing Little Snow White, Little Briar Rose, and Cinderella by The Brothers Grimm, I was able to …

Testing Mice At Risk Of Pancreatic Cancer For Altered Protein Pathways Found In Diabetes, Henley Cheung

Honors Undergraduate Theses

Pancreatic cancer is nearly asymptomatic, which can result in extensive grow and even metastasis to other organs before detection. When diagnosed at a late stage, the survival rate is 3%. Early detection is therefore the key to treating pancreatic cancer. Diabetes was identified as a risk factor for the development of pancreatic cancer, but the mechanism remains unknown. In this project, the objective was to delineate a link between diabetes and pancreatic cancer by examining their shared protein signaling pathways. In a previous study, hyper-activation of AKT1 resulted in a pre-diabetic phenotype and also increased upregulation of downstream phosphorylated mTOR …

Characterization Of Novel Borrelia Burgdorferi Transcripts Expressed During Tick And Mammalian Infection, Philip Adams

Electronic Theses and Dissertations

The purpose of this dissertation is to characterize the transcriptome of Borrelia (Borreliella) burgdorferi to discover novel transcripts, important for pathogenesis. As a spirochete and the etiological agent of Lyme disease, the foremost vector-borne bacterial infection in the world, B. burgdorferi fulfills a distinctive niche among bacterial pathogens. Persisting in the disparate environments of a tick vector and mammalian reservoirs, it is absolutely dependent on its hosts for transmission and nutrient acquisition. B. burgdorferi harbors a complex fragmented genome which is largely linear, unlike that of most prokaryotes, lacks an array of classically described metabolic genes, and contains an unusually …

The purpose of this integrative review is to examine the use of AAT focusing on canine assisted therapy (CAT) among veterans diagnosed with PTSD. The methodology involved …

Plasticity Of Central And Peripheral Nervous System: Effects Of Oxygen-Glucose Deprivation (Ogd) And Chronic Intermittent Hypoxia (Cih), Jin Chen

Electronic Theses and Dissertations

Transient receptor potential canonical 6 (TRPC6) channels are permeable to Na+ and Ca2+ and are widely expressed in the brain. In this study, we investigated the role of TRPC6 following ischemia/reperfusion (I/R) and oxygen-glucose deprivation (OGD). We found that TRPC6 expression was increased in wild type (WT) mice cortical neurons following I/R and in primary neurons with OGD, and that deletion of TRPC6 reduced the I/R-induced brain infarct in mice and the OGD- /neurotoxin-induced neuronal death. Using live-cell imaging to examine intracellular Ca2+ levels ([Ca2+]i), we found that OGD induced a significant higher increase in glutamate-evoked Ca2+ influx compared to …

Computational Fluid Dynamics Proof Of Concept And Analysis Of A Self-Powered Fontan Circulation, Marcus Ni

Electronic Theses and Dissertations

The Fontan circulation is a result of the last (third stage) surgical procedure to correct a single ventricle congenital cardiac disorder in children. Although the Fontan circulation has been successfully established in surgeries over the years, it is flawed and can lead in certain cases to pre-mature death. The main cause of this failure is due to increased pulmonary vascular resistance due to loss pulse pressure and blood flow. In healthy circulations, the heart pumps directly to the lungs, where as "Single Ventricle" patients must use a single sided heart to supply blood to the rest of the body before …

Investigating The Quantity And Types Of Microplastics In The Organic Tissue Of Oysters And Crabs In The Indian River Lagoon, Heidi Waite

Honors Undergraduate Theses

Microplastics are widespread and abundant. Few studies have examined the diversity and abundance of microplastics in wild organisms. This study determined the microplastic quantity and types in the organic tissues of the eastern oyster Crassostrea virginica and Atlantic mud crab Panopeus herbstii from the Indian River Lagoon (IRL). This study also investigated whether location affected the microplastic abundance and variety. Organisms were collected from three sites across Mosquito Lagoon in the northern IRL. Oysters were frozen after collection. Crabs were placed in containers for 5 days before freezing. The soft organic tissue was chemically digested using hydrogen peroxide, filtered, …

The Effects Of Hegemonic Support Of Endangered Languages On Language Ideologies, Christy Box

Honors Undergraduate Theses

Endangered languages are those that are spoken by a very small percentage of the population and are at risk of disappearing with all the knowledge and diversity they contain. Endangered languages often become endangered because the speakers and the society perceive the language as low status or of little use, and a positive change in perception of the language could aid in revitalizing the language. Institutions such as governments, businesses, and universities have recently begun supporting endangered languages in several areas, and this support could greatly affect language ideologies, perceptions of and attitudes about the language. In this research project, …

A Stinging Effect: The Legal Implications Biting Into The Effects Of The Zika Virus, Keanu Bader Mr

Honors Undergraduate Theses

People are afraid of contagious diseases. The thought that disease can spread throughout an entire population tends to make people wary of their interactions with their surrounding environment. Hearing about, or even seeing pictures of mosquitoes can make people squeamish or even stimulate an itch. Throughout the ages, the reaction to contagious diseases has been to quarantine and isolate. From the bubonic plague to the 1918 “Spanish” flu, the protocol was to quarantine those infected and isolate the rest. It may be this practice that inspired such precautions be taken by the public. Often these precautions are not warrantless and …

How Disgust, Physiological Activity And Moral Foundations May Predict Political Attitudes And Religious Beliefs: A Systematic Review, Kayla M. Mannion

Honors Undergraduate Theses

The goal of this research synthesis is to obtain evidence about a new and upcoming idea of how political ideology and religious beliefs may be predicted by disgust, moral codes and physiological activity. Previously, it was believed by some that politics and religion were a product of an individual's environment and influences of an individual's family and friend's beliefs. Current research is trying to explain how much a person's biology influences their beliefs. This thesis will aim to explain how it is possible to obtain these types of data and why this research is important.

Real Loneliness And Artificial Companionship: Looking For Social Connections In Technology, Fernando L. Montalvo

Honors Undergraduate Theses

Loneliness among older adults is a problem with severe consequences to individual health, quality of life, cognitive capacity, and life-expectancy. Although approaches towards improving the quality and quantity of social relationships are the prevailing model of therapy, older adults may not always be able to form these relationships due to either personality factors, decreased mobility, or isolation. Intelligent personal assistants (IPAs), virtual agents, and social robotics offer an opportunity for the development of technology that could potentially serve as social companions to older adults. The present study explored whether an IPA could potentially be used as a social companion to …

An Rnai Screen To Identify Components Of A Polyamine Transport System, Adam J. Foley

Honors Undergraduate Theses

Polyamines, specifically putrescine, spermidine, and spermine, are small cationic molecules found in all organisms. Cells can biosynthetically make these molecules, or alternatively, they can be transported from the extracellular environment. Malignant cells have been shown to require relatively high amounts of polyamines. There is a chemotherapeutic agent, DFMO, used to block the biosynthesis of polyamines. Many malignant cells can circumvent DFMO therapy by activating their transport system. A potential solution is to simultaneously block biosynthesis and transport of polyamines. However, little is known about the polyamine transport system in higher eukaryotes.

This thesis aims to add to the basic biological …

Alpha-Synuclein: Insight Into The Hallmark Of Parkinson's Disease As A Target For Quantitative Molecular Diagnostics And Therapeutics, Baggio A. Evangelista

Honors Undergraduate Theses

Parkinson’s disease (PD) is the second-most common neurodegenerative disease after Alzheimer’s disease. With 500,000 individuals currently living with Parkinson’s and nearly 60,000 new cases diagnosed each year, this disease causes significant financial burden on the healthcare system - amassing to annual expenditures totaling 200 billion dollars; predicted to increase through 2050. The disease phenotype is characterized by a combination of a resting tremor, bradykinesia, muscular rigidity, and depression due to dopaminergic neuronal death in the midbrain. The cause of the neurotoxicity has been largely discussed, with strong evidence suggesting that the protein, alpha-Synuclein, is a key factor. Under native conditions, …

High Performance Techniques For Face Recognition, Ahmed Aldhahab

Electronic Theses and Dissertations

The identification of individuals using face recognition techniques is a challenging task. This is due to the variations resulting from facial expressions, makeup, rotations, illuminations, gestures, etc. Also, facial images contain a great deal of redundant information, which negatively affects the performance of the recognition system. The dimensionality and the redundancy of the facial features have a direct effect on the face recognition accuracy. Not all the features in the feature vector space are useful. For example, non-discriminating features in the feature vector space not only degrade the recognition accuracy but also increase the computational complexity. In the field of …
