Variation In The Modified First Metatarsal Of A Large Sample Of Tapirus Polkensis And The Functional Implications For Ceratomorphs., Patrick Lawrence Hawkins

Electronic Theses and Dissertations

The Mio-Pliocene age Gray Fossil Site of northeastern Tennessee has the largest collection of tapir postcranial skeletons in the world. Though representing a single species, a few localized structures show high variability. This paper deals with variation of the first metatarsal, which in tapirs was reduced as an early adaptation for running and then retrofitted to serve as a special origin for flexors and adductors of the proximal phalanges. The first metatarsal connects the medial ankle with a posterior process of the third metatarsal in tapiroids. In Tapirus indicus, T. webbi, and 6 out of 31 T. polkensis …

A Study Of Habitat Selection And Fluctuating Asymmetry Of Amybstoma Tigrinum At Henderson Island Wildlife Management Area In Jefferson County Tn., Christopher Scott Ogle

Electronic Theses and Dissertations

Studies were conducted on a population of tiger salamanders, Ambystoma tigrinum, at Henderson Island Wildlife Management Area in Jefferson County, TN. Tests were conducted to locate the nonbreeding habitat of the salamanders and to detect any difference in fluctuating asymmetry (FA) between larval populations in a large, permanent pond and an ephemeral wetland. Drift fences were installed with pitfall traps at selected locations around each pond to determine nonbreeding habitat use by adults. Most adult salamanders were found using a blackberry (Rubus sp.) dominated old-field, a grassy field, and a shrub-grass mix field, which were all adjacent …

Population Structure Based On Age-Class Distribution Of Tapirus Polkensis From The Gray Fossil Site Tennessee., Matthew L. Gibson

Electronic Theses and Dissertations

Individuals of Tapirus polkensis from the Gray Fossil Site exhibit an excellent level of preservation. Intact skulls collected from the site were arranged in a rough age class system separated into 7 categories based on the teeth present and amount of dental wear. Such an eruption series is useful for general comparisons amongst the individual tapirs; however, the classes do not represent an age in years due to a lack of data on living tapirs. Consequently, it is possible that some age classes may contain several years of a tapirs life, or comparatively only a few months. In this study …

Molecular Modulation Of A-Subunit Visit-Dg Sequence Residue Asp-350 In The Catalytic Sites Of Escherichia Coli Atp Synthase., Sneha R. Jonnalagadda

Electronic Theses and Dissertations

ATP Synthase is the fundamental means of cellular energy production in animals, plants, and almost all microorganisms. In order to understand the mechanism of ATP catalysis, critical amino acid residues involved in Pi binding have to be identified. The αVISIT-DG sequence at the interface of α/β subunits that contains residues from 345-351 is highly conserved and αAsp-350 has been chosen because of its negative charge side chain and its close proximity (~2.8 Å) to the known phosphate binding residue αArg-376. The mutant's αD350R, αD350Q, αD350A, αR376A/D, and αG351R/A/D were generated by site directed mutagenesis and several biochemical assays were performed …

On The Cranial Osteology Of Eremiascincus And Its Use For Identification., William B. Gelnaw

Electronic Theses and Dissertations

A persistent problem for Australian paleontology has been a lack of diagnostic characters for identifying lizard fossils. Eremiascincus is one of the most widespread genera in Australia, so it was examined for distinguishing features and how it fits into a model of skink evolution. Skulls of Eremiascincus were examined within five separate contexts: 1) a description of the cranial osteology, 2) a qualitative comparison of individual cranial elements of Eremiascincus to closely related Ctenotus, 3) a description of the cranial allometry in Eremiascincus using linear morphometrics, 4) using cranial morphometrics of skinks to deduce their phylogeny, and 5) using …

The Occurrence Of An Abdominal Fauna In An Articulated Tapir (Tapirus Polkensis) Recovered From The Miocene Gray Fossil Site Northeast Tennessee., Shannon M. Mcconnell

Electronic Theses and Dissertations

The analysis of samples recovered from the abdominal area of an articulated tapir from the Late Miocene (4.5-7 million bp) Gray Fossil Site, revealed a rich palyno-fauna comprised of about 94% egg/oocyst-like structures and 6% pollen and other palynomorphs. In addition, a tight grouping of six hickory nuts (Carya) was recovered from the same area suggesting that the samples represent the abdominal contents. The analysis of a sample from immediately outside the tapir produced a sample with 98% pollen and less than 0.5% egg-like structures. The size, shape, and general morphology of egg-like structures were analyzed with light …

Ecologically Friendly Food Buying And Recycling: Environmental Attitudes And Behaviors In A Tennessee Survey., Jessica Jane King

Electronic Theses and Dissertations

This thesis focuses on pro-environmental attitudes and behaviors and the interactions between recycling behavior, food buying attitudes, food buying behaviors, and ecological beliefs. Following an introductory chapter, I present an article-length paper on recycling behavior to be submitted to Environment and Behavior. Data for this study came from a telephone survey of Tennessee residents (N=270). Using OLS regression analysis, I find that recycling behavior is significantly related to access to recycling facilities. I do not find a significant interaction effect between access to recycling facilities and willingness to recycle. I conclude by suggesting that pro-environmental policies need to make structural …

Mapping England's Trade Through Depictions In English Emblems., Valerie J. Erickson

Electronic Theses and Dissertations

This thesis explores the growing interaction between England and foreign countries comparing their trade with contemporary later sixteenth century and seventeenth century English emblems. The emblems used are those available over the internet from several different library and university sources. As England expanded its trade throughout the world, English emblems began to show the exchange occurring between England and its various trading partners. Historians have largely overlooked this valuable source of information. By studying emblems historians gain invaluable insight into the economy, society, politics, religion, and other matters with which England was concerned.

Exploring The Use Of Visual Journaling During Art Therapy Internships: A Self Study, Mary Madison Lovett

EVMS School of Health Professions Theses & Dissertations

Reflective processes and journaling have been given great attention in the literature as effective tools for the enrichment of learning and professional growth (Boud, 2001). Self reflection in response to clinical experiences can help students can gain a deep level of meaning and insight. Visual journaling is one method of self reflection about which there is little scholarly literature. The process of visual journaling integrates self reflection and exploration through creative imagery and written reflection.

I conducted a qualitative self study which was an exploration of visual journaling as I experienced two semesters of clinical internships. During the study I …

Alternative Strategies For Managing Pharmaceutical And Personal Care Products In Water Resources, Gabriel Eckstein, George William Sherk

Faculty Scholarship

In recent decades, concern has grown over the presence of pharmaceutical and personal care products (PPCPs) in water. This concern stems from the possibility that the presence of PPCPs in water supplies may pose a threat to both human and environmental health. Such threats may be both direct (e.g., exposure to endocrine disrupting compounds) and indirect (e.g., emergence of antibiotic resistant bacteria). The water treatment and wastewater treatment community has been especially concerned over PPCPs because of PPCPs ubiquitous nature and their ability to persist or only partially degrade in water and during wastewater treatment. Studies done over the past …

Vitamin D And Malignant Melanoma Outcomes, Jenna L. Green

Theses and Dissertations

Ultraviolet exposure from sunlight and other sources is the major risk factor for the development of malignant melanoma of the skin. Exposure to sunlight is also the main pathway the human body obtains vitamin D. Cell proliferation, differentiation and inhibition is mediated in part by vitamin D, leading researchers to suspect vitamin D has a protective role in various cancers, including melanoma. The purpose of the project was to review the current available literature focusing on the relationship between vitamin D levels and melanoma outcomes. The review of the literature was designed to address the clinical question: What is the …

Preventing The Spread Of Infections In Patients' Homes: What Is The Best Evidence?, Julie Ferry

Theses and Dissertations

Nurses need evidence-based practices to prevent the spread of infections in patients' homes. Nursing equipment must be cleaned and disinfected properly between patients and proper hand hygiene should be done to decrease health-care associated infections in the home and community setting. A review and synthesis of the most current literature was done by searching the Cumulative Index to Nursing and Allied Health literature (CINAHL), Cochrane Database, Google Scholar™ and Google™ databases. Key words include infection control, home visits, public health, cleaning, home health, equipment, disinfectants and combinations of those words. Tools were created for dissemination to nurses providing care in …

Theory-Derived Approaches To Behavioral And Psychological Symptoms Of Dementia, Bethany Speece

Theses and Dissertations

As the world's population ages, the prevalence of Alzheimer's disease and other conditions that cause dementia is expected to increase. Although there is some awareness of the dangers of psychotropic drugs used to address behavioral and psychological symptoms of dementia, all too often these agents continue to be used as first-line treatment. Nurses need to be cognizant of safer, efficacious, holistic nonpharmacological approaches and utilize these in an individualized, systematic manner. Two mid-range nursing theories, the Need-Driven Dementia-Compromised Behavior model and the Progressively Lowered Stress Threshold model, provide conceptual frameworks for nonpharmacological interventions. This paper examines these models and describes …

Intermediate Filaments Regulate Tissue Size And Stiffness In The Murine Lens, Douglas S. Fudge, John V. Mccuaig, Shannon Van Stralen, John F. Hess, Huan Wang, Richard T. Mathias, Paul G. Fitzgerald

Biology, Chemistry, and Environmental Sciences Faculty Articles and Research

PURPOSE. To define the contributions of the beaded filament (BF), a lens-specific intermediate filament (IF), to lens morphology and biomechanics.

METHODS. Wild-type and congenic CP49 knockout (KO) mice were compared by using electrophysiological, biomechanical, and morphometric approaches, to determine changes that occurred because of the absence of this cytoskeletal structure.

RESULTS. Electrophysiological assessment established that the fiber cells lacking the lens-specific IFs were indistinguishable from wild-type fiber cells. The CP49 KO mice exhibited lower stiffness, and an unexpected higher resilience than the wildtype lenses. The absence of these filaments resulted in lenses that were smaller, and exhibited a higher ratio …

Public Perception Of Desalinated Produced Water From Oil And Gas Field Operations: A Replication, Gene L. Theodori, Mona Avalos, David B. Burnett, John A. Veil

Journal of Rural Social Sciences

This study is a replication of Theodori et al.’s (2009) research on public perception of desalinated produced water from oil and gas field operations. The data used in this paper were collected in twelve Texas counties. Overall, the findings of this investigation paralleled those uncovered in Theodori et al.’s original exploration. Our data reveal that small percentages of respondents are extremely familiar with the process of desalination and extremely confident that desalinated water could meet human drinking water quality and purity standards. Our data also indicate that respondents are more favorably disposed toward the use of desalinated water for purposes …

Production Of Fermentable Sugars And Lipids By Microalgae From Secondarily Treated Municipal Wastewater, Jen Chao Liu

Theses and Dissertations

In this paper, replacing complete or partly of growth mediums with secondarily wastewater was studied. Lipid content of Neochloris oleoabundans grown in a 0.3 X SE medium and autoclaved secondarily treated wastewater mixture was 22.27 % (w/w). The maximum biomass concentration of N. oleoabundans grown in wastewater with no additional nutrients was 0.636 g/L with 33% (w/w) glucose. Two culture lines, MA, and NA were isolated within our laboratory and could grow in secondarily treated wastewater with no additional nutrients. The maximum biomass concentration of MA in batch culture was 0.860 g/L and the sum of glucose and xylose was …

Ancient Mitochondrial Dna From Pre-Historic Southeastern Europe: The Presence Of East Eurasian Haplogroups Provides Evidence Of Interactions With South Siberians Across The Central Asian Steppe Belt, Jeremy R. Newton

Masters Theses

Studies of mitochondrial DNA (mtDNA) polymorphism have provided valuable insights for understanding patterns of human migration and interaction. The ability to recover ancient mtDNA sequence data from post-mortem bone and tissue samples allows us to view snapshots of historic gene pools firsthand, provided that great care is taken to prevent sample contamination. In this study, we analyzed the DNA sequence of the first hypervariable segment (HVSI) of the mtDNA control region, as well as a portion of the coding region, in 14 individuals from three collective burials from the Neolithic Dnieper-Donetz culture and three individuals from Bronze Age Kurgan burials, …

A Minimum Spanning Tree Based Clustering Algorithm For High Throughput Biological Data, Harun Pirim

Theses and Dissertations

A new minimum spanning tree (MST) based heuristic for clustering biological data is proposed. The heuristic uses MSTs to generate initial solutions and applies a local search to improve the solutions. Local search transfers the nodes to the clusters with which they have the most connections, if this transfer improves the objective function value. A new objective function is defined and used in the heuristic. The objective function considers both tightness and separation of the clusters. Tightness is obtained by minimizing the maximum diameter among all clusters. Separation is obtained by minimizing the maximum number of connections of a gene …
