An Analysis Of Prevalence Of Chytrid Fungus In An Amphibian Assemblage In Middle Tennessee, Cameron Brocco
An Analysis Of Prevalence Of Chytrid Fungus In An Amphibian Assemblage In Middle Tennessee, Cameron Brocco
Honors Theses
Chytridiomycosis is an infectious, fungal disease largely seen in amphibians, which is caused by the highly virulent, zoosporic, pathogenic, single-celled fungus Batrachochytrium dendrobatidis (Bd). It is known to cause epidermal hyperplasia, hyperkeratosis, skin ulcerations, and fatalities by asystolic cardiac arrest either from shifts in electrolytes or increased acidity in the blood plasma. Previous research has demonstrated that urban water bodies have a higher prevalence of chytrid fungus than rural water bodies. Researchers have also found that chytrid is more prevalent in open canopy habitats than closed canopy habitats. Furthermore, it is implicated in global population declines and local extinctions in …
A Biotic Survey Of Outcroppings And Pinctada Longisquamosa In Oyster Pond, San Salvador Island, Bahamas, One Year After Hurricane Joaquin, Ashton Selah Mitchell
A Biotic Survey Of Outcroppings And Pinctada Longisquamosa In Oyster Pond, San Salvador Island, Bahamas, One Year After Hurricane Joaquin, Ashton Selah Mitchell
Honors Theses
Oyster Pond is one of the marine inland ponds located on San Salvador Island, Bahamas. Oyster Pond has connections to the ocean through a series of conduits in the pond, which cause the salinity of the pond to be marine pond, except after a hurricane and during a drought. Oyster Pond has a variety of marine life such as algae, small fish, and invertebrates occurring in mangroves, flocculent, conduits, and biotic outcroppings. The focus of this research was to evaluate the impact of the 2015 Hurricane Joaquin (17 months later) on water chemistry and the marine life of the biotic …
Effectiveness Of Conservation Education At The Chattanooga Zoo, Luke Allen Black
Effectiveness Of Conservation Education At The Chattanooga Zoo, Luke Allen Black
Honors Theses
Conservation is the central focus of many modern zoos and aquariums. These zoos incorporate guest education to facilitate a connection between zoo guests and animal conservation. I conducted a study at the Chattanooga Zoo and the University of Tennessee at Chattanooga which examined two modern zoo education approaches. The two approaches utilized in the study are currently used in keeper chats at the Chattanooga Zoo. The first approach is an emotional appeal (an appeal to the personalities of the chimps at the zoo) and the second approach is a utilization of a take-action initiative (recycling cell phones to reduce mining …
Predicting The Author Of Twitter Posts With Markov Chain Analysis, Daniel Freeman
Predicting The Author Of Twitter Posts With Markov Chain Analysis, Daniel Freeman
Honors Theses
Given a set of text with known authors, is it possible to take new text, not knowing who wrote it, and correctly identify the author? One way to do this is to analyze the text using Markov chains. This research project will first attempt to answer this question using books available in the public domain. Using what is learned from trying to identify authors of books, the primary goal of this project is to identify the best way to guess the author of a post on the social media network Twitter using Markov chains.
Statistical Linear Mixed Models For Evaluation Of Training Program In Hand Surgery Chief Residents, Zoe Michelle Ross
Statistical Linear Mixed Models For Evaluation Of Training Program In Hand Surgery Chief Residents, Zoe Michelle Ross
Honors Theses
Resident clinics (RCs) are intended to catalyze the achievement of educational milestones through progressively autonomous patient care. However, few studies quantify their effect on competency-based surgical education, and no previous publications focus on hand surgery RCs. This study aims to use statistical theories and knowledge of descriptive statistics and inference statistics, such as confidence intervals, two sample t-tests, correlation and association tests, as well as statistical model building such as analysis of variance with random effects and mixed linear models. We hypothesize that the higher a resident’s training years, the higher the autonomy score (quality of surgery) will be. We …
Developmental Steroids And Vitamins: Identified And Quantified In Predatory Lady Beetles, Andrea Hixson
Developmental Steroids And Vitamins: Identified And Quantified In Predatory Lady Beetles, Andrea Hixson
Honors Theses
Autumn brings ladybeetles into homes to seek shelter during the winter, which is a nuisance. Their bites may induce an allergic reaction resulting in painful rashes. Predatory ladybeetles have been used as a biological control agents. Not only do they feed on ecological pests, they also feed on the saps of ripe fruits reducing the value of the damaged crop. Two species of ladybeetles (Coleoptera: Coccinellidae) will be examined to determine the quantities of steroids and vitamins used throughout their life stages. The species examined are native, Hippodamia convergens, of North America, and an invasive, Harmonia axyridis, of Asia. The …
The Effects Of E-Cigarette Exposure On Cell Viability And Gene Expression, Christine Hale
The Effects Of E-Cigarette Exposure On Cell Viability And Gene Expression, Christine Hale
Honors Theses
Marketed as a safer alternative to tobacco products, the popularity of e-cigarette use is on the rise. However, little is known about the potential health risks associated with their use. Many e-cigarette filling solutions are known to contain significant levels of tobacco alkaloids, including nicotine, anabasine, myosmine and cotinine. Using a panel of lung cell cultures distinguished by differences in sex and disease status, this study addresses the in vitro effects of common tobacco alkaloids found in e-cigarettes on cell proliferation and gene expression. We hypothesize that alkaloid exposure of lung cells is associated with abnormal proliferation and gene expression, …
Octahedral Ruthenium(Ii) Complexes For C-H Bond Activation And Olefin Hydroarylation, Patrick Z. Zdunek
Octahedral Ruthenium(Ii) Complexes For C-H Bond Activation And Olefin Hydroarylation, Patrick Z. Zdunek
Honors Theses
The study of inert C-H bond activation of hydrocarbons has been gaining interest. As these hydrocarbons are used in the production of many consumables such as fuel, plastics, and detergents, it is necessary to efficiently utilize the finite quantity of petroleum feedstocks. Transition metal complexes are incorporated as catalysts into synthetic routes to create new C-X (X = C, N, O) bonds in order to increase the chemical value of organic molecules. The complex [Ru(η6-p-cymene){P(OCH2CF3)3}(Ph)(OTf)] (1) (P{OCH2CF3}3 = tris(2,2,2-trifluoroethyl) phosphite, Ph = phenyl, OTf = trifluoromethanesulfonate) was prepared and tested for functionality as a catalyst in olefin hydroarylation. Catalytic reactions …
Emphasizing Colonization In Modern Environmental And Women’S Activist Movements In India And The Future Of Ecofeminist Movements For Creating A More Just And Sustainable Future, Alea M. Tveit
Honors Theses
This research discusses the extent of colonial acknowledgement in modern women’s rights and environmental movements in India. British colonization profoundly altered the ecological landscape and social norms of the societies it affected while leaving behind institutional structures that encouraged and perpetuated discrimination, oppression, and environmental degradation. In the case of India, I illustrate pre-colonial norms surrounding environmental stewardship and women’s rights and compare it to post-colonial ideology to make a connection of modern human rights and environmental problems to a colonial past. Today’s popular environmental and women’s activist movements are analyzed to determine if colonial acknowledgment or a decolonial framework …
Fluorescence And Uv-Vis Studies Of Quinone-Induced Protein Modifications, Charles A. Thomas Jr
Fluorescence And Uv-Vis Studies Of Quinone-Induced Protein Modifications, Charles A. Thomas Jr
Honors Theses
Quinones are the metabolites of a class of chemicals known as polycyclic aromatic hydrocarbons. These chemicals have been found to be toxic in the environment, especially when interacting with certain proteins. In this study, we investigated the modification of Lysozyme and Ribonuclease A by a series of benzoquinones as well as few naphthoquinones. Fluorescence spectroscopy was used to measure the degree of modification of Lysozyme and Ribonuclease A when incubated with quinones at differing concentrations and for various times. All reactions, unless noted, were carried out in a phosphate buffer (pH=7.0) at 37°C to mimic physiological conditions. The fluorescence intensity …
A Study Of The Photoacoustic Effect In Ethylene Gas, Jay Nguyen
A Study Of The Photoacoustic Effect In Ethylene Gas, Jay Nguyen
Honors Theses
Ethylene, C2H4, is a plant hormone produced and released naturally by plants and soil microorganisms. This colorless, flammable gas has a slightly sweet odor usually only recognized by those who have handled ethylene before. In situ analyses of this gas and many other potentially harmful gases outside of the laboratory are often difficult to perform due to the lack of a portable yet reliable unit capable of precisely and accurately detecting and measuring the concentrations of these gases at trace gas concentrations of a few parts per billion. In this research project, photoacoustic spectroscopy was used to detect and measure …
