Diversity And Function Of Fungi Associated With The Fungivorous Millipede, Brachycybe Lecontii, Angie M. Macias
Diversity And Function Of Fungi Associated With The Fungivorous Millipede, Brachycybe Lecontii, Angie M. Macias
Graduate Theses, Dissertations, and Problem Reports (ETD)
Brachycybe (Wood) is a genus of fungivorous millipedes. To date, the fungal associates of these millipedes have never been characterized. In an attempt to resolve these relationships, culture-based approaches combined with DNA barcode sequencing were used. Sampling of 313 individuals collected from three of four B. lecontii clades and 20 sites across seven states uncovered at least 183 genera in 40 orders from four fungal phyla. At least seven putative new species were recovered in this study, despite the use of more classical culture-based approaches. Three of these fungi were phylogenetically resolved using ITS + LSU and include two new …
Storytelling, Survival, And Child Figures In Contemporary American Life-Writing, Yvonne Michelle Swartz Hammond
Storytelling, Survival, And Child Figures In Contemporary American Life-Writing, Yvonne Michelle Swartz Hammond
Graduate Theses, Dissertations, and Problem Reports (ETD)
My dissertation explores strategies for survival primarily related to acts of storytelling, and more specifically storytelling with the tacit agreement for measures of truth, what I refer to in my title as life-writing. The term "life-writing" refers broadly to literary and theatrical works that are connected to the lived-experience. The texts I examine, all written in the U.S. after 1990, consider the impact of traumatic and unjust pasts through sweeping, epic narratives. Each of these texts tells a separate story about injustice through stories that reveal children as victims of discursive and/or actual violence arising out of conflict between and …
Identification Of Snps Potentially Associated With Asthma Using A Di-Isocyanate Luciferase Reporter Assay, Wentao Jiang
Identification Of Snps Potentially Associated With Asthma Using A Di-Isocyanate Luciferase Reporter Assay, Wentao Jiang
Graduate Theses, Dissertations, and Problem Reports (ETD)
Occupational Asthma (OA) is a common lung disorder that can be caused or aggravated by exposures and conditions in the work places. Di-isocyanate asthma (DA) is one type of OA. Despite years of research, there are no reliable markers to predict risk or susceptibility for DA. Previous studies have identified 23 candidate single nucleotide polymorphisms (SNPs) that are potentially associated with genes that are related with DA. In this study, we tested the functional relevance of the 23 candidate SNPs (mostly intronic) in several DA-related genes. We hypothesized that some of these SNPs may affect the binding of relevant transcription …
Study Of Parameter Estimation And Model Calibration Using Bayesian Analysis Of Noisy Data For A Virus Model, Alejandro Mejia
Study Of Parameter Estimation And Model Calibration Using Bayesian Analysis Of Noisy Data For A Virus Model, Alejandro Mejia
Graduate Theses, Dissertations, and Problem Reports (ETD)
Numerous engineering problems are concerned with the challenge of representing real life systems through mathematical equations: modeling. Properly generated mathematical models can accurately predict the behavior of natural processes. The key objective of model development is to correctly build a set of equations or expressions that can reproduce the results observed from experimental measurements. By following this methodology, sources of error and uncertainty will arise as most natural processes have random factors that make the results stochastic, and therefore can never be exactly reproduced. A model can try to best approximate the actual outcome, but many times assumptions or simplifications …
Inhibiting The Cannabinoid Catabolic Enzyme Magl To Potentiate The Anti-Arthritic Properties Of The Synthetic Glucocorticoid Dexamethasone, Sara R. Nass
Graduate Theses, Dissertations, and Problem Reports (ETD)
Rheumatoid arthritis (RA, Table 1) is the most common type of inflammatory arthritis, and is characterized by swelling, inflammation, pain, and destruction of the synovial joints (i.e., knees, elbows, wrists, hips, and fingers). Glucocorticoid receptor agonists are a type of steroid hormone and are among the most common treatments for inflammatory arthritis because of their powerful anti-inflammatory effects. However, harmful side effects are associated with these glucocorticoids (GCs), including increasing patients' vulnerability to infections. Cannabinoids (i.e., cannabis-like signaling molecules) exert anti-inflammatory and analgesic effects with limited side effects compared to traditional immunosuppressants making them excellent targets for the development of …
Cannabinoid Withdrawal Produces Altered Somatic And Emotionality-Related Behavior In Mice, Kristen R. Trexler
Cannabinoid Withdrawal Produces Altered Somatic And Emotionality-Related Behavior In Mice, Kristen R. Trexler
Graduate Theses, Dissertations, and Problem Reports (ETD)
Cannabis sativa is the most commonly abused illicit drug in the United States. An estimated 9 percent of those who use cannabis will develop some level of cannabinoid use disorder (CUD). Although behavioral therapy has some success in treating CUD, many users still relapse. Moreover, there are no FDA approved pharmacological treatments available to complement behavioral therapy. The need for appropriate treatments highlights the need for nonhuman animal models to test target compounds. The current study aimed to (1) evaluate the MAGL inhibitor JZL184 as a possible treatment for cannabinoid withdrawal, and (2) to develop a spontaneous model of cannabinoid …
A Literature Review Of The Effects Of Home And Commercial Processing Methods On Nutritional And Sensory Properties Of Green Beans (Phaseolus Vulgaris), Emily Hope Bauman
A Literature Review Of The Effects Of Home And Commercial Processing Methods On Nutritional And Sensory Properties Of Green Beans (Phaseolus Vulgaris), Emily Hope Bauman
Graduate Theses, Dissertations, and Problem Reports (ETD)
A comprehensive review of current literature was conducted to investigate nutrient retention, texture and color during processing and storage of green beans. Consumers do not take into consideration of the effects of processing and storage on the nutritional and sensory quality of the green beans. Freezing and canning are the main processing methods used to extend the shelf-life of green beans. Both frozen and canned green beans are blanched during processing. Green beans are either frozen after blanching or for canning undergo additional thermal processing. Ascorbic acid was found to remain stable after steam blanching at 90°C for 3.5 minutes. …
Using A Multi-Omic Approach To Investigate A Diet Intervention In Young Adults At Risk Of Disease, Oluremi Ariel Famodu
Using A Multi-Omic Approach To Investigate A Diet Intervention In Young Adults At Risk Of Disease, Oluremi Ariel Famodu
Graduate Theses, Dissertations, and Problem Reports (ETD)
Background: Poor dietary behaviors are widely recognized in the role of development and course of a variety of illnesses, including but not limited to cardiovascular disease, obesity, and diabetes. Young adults have increased risk due to poor dietary behaviors, especially as they transition into a college setting. The evidence demonstrates an urgency for developing treatment and prevention through dietary intervention approaches in this population. In addition to improper diet, investigators have connected abnormal gut microbiome (i.e. the collection of genes from our intestinal microbiota) to inflammation and obesity, therefore momentum has gained in treating the altered gut microbiome with dietary …
Characterization Of Insulin Sensitivity And The Plasma Lipidome In Periparturient Dairy Cows, Sina Saed Samii
Characterization Of Insulin Sensitivity And The Plasma Lipidome In Periparturient Dairy Cows, Sina Saed Samii
Graduate Theses, Dissertations, and Problem Reports (ETD)
During the transition from gestation to lactation, dairy cows experience negative energy balance due to an increased demand for energy to support milk production coupled with inadequate energy intake. Energy deficit during the peripartum is associated with the development of insulin resistance which contributes to adipose tissue lipolysis. In turn, elevated free fatty acids (FFA) in circulation increase triacylglycerol (TAG) deposition in liver. This metabolic impairment is known to cause postpartum metabolic diseases including fatty liver and ketosis. Consequently, postpartum metabolic disease can lead to reduced milk production in early lactation, impaired reproductive performance, and increased culling rates. Moreover, cows …
The American Hunting Story And The Formation Of Environmental Literature., Jericho Williams
The American Hunting Story And The Formation Of Environmental Literature., Jericho Williams
Graduate Theses, Dissertations, and Problem Reports (ETD)
This dissertation addresses the almost complete absence of American hunting stories in the subfield of environmental literature within American literature. Since environmental literature’s inception in the early 1990s with The Norton Book of Nature Writing (1990) and American Earth: Environmental Writing Since Thoreau (2008), environmental literary scholars have failed to take into account the roles of hunters in advancing conservationist measures to protect and preserve wildlife and lands throughout America from the early nineteenth century through the present day. This project seeks to build a bridge between environmental literary scholars and environmentalists far removed from hunting traditions and those whose …
"Our Own Flesh And Blood?": Delaware Indians And Moravians In The Eighteenth-Century Ohio Country., Jennifer L. Miller
"Our Own Flesh And Blood?": Delaware Indians And Moravians In The Eighteenth-Century Ohio Country., Jennifer L. Miller
Graduate Theses, Dissertations, and Problem Reports (ETD)
Between 1740 and 1790, Moravians and Delaware Indians fostered a spiritual and political alliance even as they endured a series of internal divisions and external threats. Although the relationship withstood the Seven Years’ War, the American Revolution splintered both groups and estranged them from their neighbors. When the Revolution ushered in a radical new democracy that undermined the authority of eastern leaders, the Moravians proved powerless to control white settlers who enforced their own vision of justice against Native peoples. The Moravian-Delaware partnership unraveled as the dramatic upheaval of the American Revolution fundamentally reshaped the political landscape and rendered the …
Effect Of Micro-Osteoperforations On Orthodontic Tooth Movement With Clear Aligner Treatment., Dobin Choi
Effect Of Micro-Osteoperforations On Orthodontic Tooth Movement With Clear Aligner Treatment., Dobin Choi
Graduate Theses, Dissertations, and Problem Reports (ETD)
Background and Objectives: Micro-osteoperforation (MOP) is a relatively noninvasive procedure to expedite the rate of orthodontic tooth movement (OTM) by enahncing naturally occurring inflammatory response. This procedure is often combined with clear aligner treatment (CAT) in order to shorten the duration of aligner wear. However, the question yet remained whether the accuracy of OTM was maintained if the patients switched the aligners more frequently than recommended. The objectives of the study were to investigate the effect of MOPs on the accuracy of anterior OTM and to evaluate the differential effect of MOPs on gender, age, severity of the mal-alignment, and …

Graduate Theses, Dissertations, and Problem Reports (ETD)
Using selected 78-rpm era recordings of Claude Debussy’s Syrinx, this research will explore the development of flute vibrato in early twentieth century recordings (ca. 1928-1953). The recordings that will be used in this case study include those of prominent flutists Marcel Moyse (recordings from 1928 and 1950), Martin Ruderman (1947 – 1948), Jean Pierre-Rampal (1949), and William Kincaid (1950 and 1953). The range of recordings include those of studio quality as well as live performances on Library of Congress Music Division Concerts, each selected from Susan Nelson’s The Flute on Record: The 78 Rpm Era: A Discography and further narrowed …
The Utility Of Fine-Scale Remote Sensing Data For Modeling Habitat Characteristics And Breeding Bird Species Distributions In An Appalachian Mature Deciduous Forest., James Sheehan
Graduate Theses, Dissertations, and Problem Reports (ETD)
In this study, I tested the potential for remote sensing data with a high spatial resolution to model breeding forest bird species and their habitat at a fine spatial scale. The research took place on ridgetops in a large, relatively contiguous Appalachian mature deciduous forest in northwestern WV, USA. The remote sensing data sources were a leaf-on QuickBird satellite image (0.6-m panchromatic and 2.4-m multispectral) and a 3-m digital elevation model (DEM). For the first part of the study, I extracted spectral and textural measures from the satellite image and terrain information from the DEM. I then used these data …
Phosphorus Determination In Forage And Manure Using Portable X-Ray Fluorescence Spectroscopy To Support Comprehensive Nutrient Management Planning, Yadav Sapkota
Graduate Theses, Dissertations, and Problem Reports (ETD)
Phosphorus (P) runoff from agricultural fields is a major cause of water quality degradation problems. A P mass balance across the farm could maintain profitability and sustainability of animal-based farms and minimize water quality problems. Comprehensive Nutrient Management Plans (CNMPs) require mineral composition, especially P, data on soil, forage, and manure samples for accurate planning. However, traditional wet chemical methods of P determination are costly, time-consuming, and generate hazardous waste. X-ray fluorescence (XRF) could overcome many of these disadvantages and allow rapid determination of P concentrations. Portable XRF (PXRF) units are Energy Dispersive (ED) systems with low power X-ray tubes …
Radial Growth Patterns In Trees Surviving Canopy Gap Disturbances, Ruth A. Stetler
Radial Growth Patterns In Trees Surviving Canopy Gap Disturbances, Ruth A. Stetler
Graduate Theses, Dissertations, and Problem Reports (ETD)
Forest disturbance regimes in eastern North America have long been conceptualized as localized gap disturbances, but recent studies suggest that more widespread, infrequent disturbance events may also be important. However, uncertainties in tree-ring methods used to detect disturbance, and in the factors that drive growth release of trees, limit the conclusions that can be drawn from regional disturbance analyses. I designed a study to further elucidate forest disturbance dynamics in eastern North America by using two approaches: 1) a case study examining the sensitivity of the radial growth averaging method of detecting disturbance and the factors influencing detection of a …
If A Rail Keks And No One Is Around, Does It Make A Sound?: Investigating The Use Of Autonomous Recording Units To Monitor King And Clapper Rails, Lydia Lenora Stiffler
If A Rail Keks And No One Is Around, Does It Make A Sound?: Investigating The Use Of Autonomous Recording Units To Monitor King And Clapper Rails, Lydia Lenora Stiffler
Graduate Theses, Dissertations, and Problem Reports (ETD)
Secretive marsh birds are challenging to monitor due to the difficulty in locating and trapping them within the dense emergent vegetation they occupy. Recently autonomous recording units (ARUs) have emerged as a novel alternative method to survey birds, although the technology has only been applied to a few species in specific field settings. There is limited information on how ARUs compare to human surveyors or how best to use ARU data that can be collected continuously. This thesis examines the applicability of ARUs for monitoring King (Rallus elegans) and Clapper ( R. crepitans) rails (collectively "rails") in two tidal marsh …
Biopolitical Cyborgs In Post-1980 North American Critical Dystopias, Valerie Ann Surrett
Biopolitical Cyborgs In Post-1980 North American Critical Dystopias, Valerie Ann Surrett
Graduate Theses, Dissertations, and Problem Reports (ETD)
Stories of babies born from transplanted uteruses, fetuses created from three biological parents, a booming global surrogacy market, and embryonic gene selection have all made national headlines in the past two years. We live in an era of science fictional childbirths. Reproductive technologies that didn't exist a decade ago are now peddled to whomever can afford them, and science fiction has responded. Post-1980 speculative fiction confronts a potent convergence of various sociopolitical and reproductive trends, including the rise of neoliberal conservatism; the "test tube baby" boom; polarized reproductive rights debates; and Diamond v. Chakrabarty (1980), the Supreme Court decision granting …
Disruptions In Operant Behavior Of Pigeons In Transitions Across Rich And Lean Schedules Of Reinforcement With And Without Advance Notice Of The Lean Schedule, Forrest J. Toegel
Disruptions In Operant Behavior Of Pigeons In Transitions Across Rich And Lean Schedules Of Reinforcement With And Without Advance Notice Of The Lean Schedule, Forrest J. Toegel
Graduate Theses, Dissertations, and Problem Reports (ETD)
"Advance notice" refers to procedures in which a stimulus is provided to signal the end of an ongoing activity and the nature of the upcoming activity. Applied research has considered whether advance notice will reduce the problem behavior that sometimes occurs during transitions. Interpretation of this research is complicated by procedural variations in the type of transitions arranged, the consequences of transition-related problem behavior, the method of providing advance notice, and the measurement of the effects of advance notice. The present experiment investigated effects of advance notice using an animal model of transition-related problem behavior. Key-pecking was maintained on a …
The Response Of Naturally Regenerating Hardwood Seedlings To Post-Harvest Weed Control And Fertilization, Kevin Andrew Tomlinson
The Response Of Naturally Regenerating Hardwood Seedlings To Post-Harvest Weed Control And Fertilization, Kevin Andrew Tomlinson
Graduate Theses, Dissertations, and Problem Reports (ETD)
Current models to predict post-harvest success rely upon pre-harvest regeneration assessments, which rarely occur. Furthermore, these models lack management recommendations to improve regeneration success of naturally regenerating desired hardwood species following overstory removal. Factorial combinations of weeding and fertilization were randomly assigned to individual naturally regenerating black cherry (Prunus serotina Ehrh.), chestnut oak (Quercus montana Willd.), white oak (Quercus alba L.), and red oak (Q. rubra L., Q. velutina Lam., and Q. coccinea Muenchh.) seedlings in the spring of 2015, three growing seasons post-harvest. Factorial ANOVA models with size at treatment application as a covariate were developed and showed species-specific …
Simulation Of Venturi Tube Design For Column Flotation Using Computational Fluid Dynamics, Wan Wang
Simulation Of Venturi Tube Design For Column Flotation Using Computational Fluid Dynamics, Wan Wang
Graduate Theses, Dissertations, and Problem Reports (ETD)
Froth flotation is one of the most important methods in mineral processing. Previous studies have found that using cavitation bubbles reduces both energy consumption and operating costs. Hydrodynamic cavitation is the most economical method used for creating tiny bubbles for flotation. In this study, the efficiency of cavitation bubble generating devices and their geometry design is analyzed using computational fluid dynamics (CFD).;To optimize the geometric design of the venturi tube, a response surface method was conducted for evaluating the effect of six important parameters affecting the efficiency of the venturi tube. Critical velocities of cavitation of different designs were compared. …
Characterization And Shelf-Life Of Soluble Protein Powder Derived From Silver Carp (Hypophthalmichthys Molitrix), Derek Warren
Characterization And Shelf-Life Of Soluble Protein Powder Derived From Silver Carp (Hypophthalmichthys Molitrix), Derek Warren
Graduate Theses, Dissertations, and Problem Reports (ETD)
Better management of current resources is one method to feed an ever growing population. Currently, sarcoplasmic proteins, water soluble proteins making up 25--30% of total protein in fish, are disposed of through municipal water treatment in surimi waste wash water. There is potential for the development of a simple method to reclaim and repurpose soluble protein from surimi wash water. The objective of this research was to 1) determine if processing temperature impacted protein recovery, 2) characterize the soluble protein powder, and 3) compare shelf stability to that of a similar protein powder (80% whey protein concentrate WPC). Separation temperature …
A Strain Theory Of Prosocial Behavior, Mallory Slusser
A Strain Theory Of Prosocial Behavior, Mallory Slusser
Graduate Theses, Dissertations, and Problem Reports (ETD)
Agnew's General Strain Theory proposes that strain leads to negative emotions, which in turn lead to crime and delinquency. However, there has been a lack of research on what happens when the negative emotions that result from externally experienced strains lead to responses other than crime. The psychology literature on "feeling bad, doing good" indicates that internally experienced negative emotions can lead to helping behaviors. The purpose of this research is to examine if externally generated negative emotions can also lead to helping or prosocial behaviors. Particular attention is given to the type of negative emotion that is experienced -- …
Endoplasmic Reticulum Stress Is Transmissible Among Cells Of The Central Nervous System, Neil T. Sprenkle
Endoplasmic Reticulum Stress Is Transmissible Among Cells Of The Central Nervous System, Neil T. Sprenkle
Graduate Theses, Dissertations, and Problem Reports (ETD)
Improper protein folding and trafficking are common pathological events observed in various cell types in neurodegenerative diseases. If the protein quality control mechanisms of the endoplasmic reticulum (ER) fail to re-establish proteostasis, misfolded proteins accumulate within the lumen of the ER and perturb normal cellular processes. While low-level stimulation of the unfolded protein response (UPR) is considered a beneficial physiological response to transient protein misfolding stress, or ER stress, sustained UPR activation resulting from prolonged ER stress can promote neurotoxicity. The cell-autonomous mechanisms of the UPR have been extensively characterized in the context of neuropathology. Nevertheless, there still remain unanswered …
Effects Of Systematic Sleep Fragmentation On Tolerance And Threshold In A Pressure Pain Task: Associations With Sustained Attention, Margeaux Marissa Gray
Effects Of Systematic Sleep Fragmentation On Tolerance And Threshold In A Pressure Pain Task: Associations With Sustained Attention, Margeaux Marissa Gray
Graduate Theses, Dissertations, and Problem Reports (ETD)
Purpose: Pain is amplified following partial sleep deprivation. Pain has not been evaluated after sleep interruption, when total sleep time is preserved. Sleep interruption, also called sleep fragmentation, is ecologically relevant because it is caused by common sleep disorders such as Obstructive Sleep Apnea [OSA], Upper Airway Resistance Syndrome [UARS] and Periodic Limb Movements Disorder [PLMD]. The Sleep Continuity Hypothesis posits that the restorative effects of sleep are related to sleep quality in addition to quantity. With this study, my goal was to evaluate whether sleep fragmentation affected pain threshold and/or tolerance by systematically fragmenting the sleep of otherwise healthy …
Robust Specularity Removal From Hand-Held Videos, Priyaankadevi Guggilapu
Robust Specularity Removal From Hand-Held Videos, Priyaankadevi Guggilapu
Graduate Theses, Dissertations, and Problem Reports (ETD)
Specular reflection exists when one tries to record a photo or video through a transparent glass medium or opaque surfaces such as plastics, ceramics, polyester and human skin, which can be well described as the superposition of a transmitted layer and a reflection layer. These specular reflections often confound the algorithms developed for image analysis, computer vision and pattern recognition. To obtain a pure diffuse reflection component, specularity (highlights) needs to be removed. To handle this problem, a novel and robust algorithm is formulated. The contributions of this work are three-fold.;First, the smoothness of the video along with the temporal …
Characterization Of The Immune Response To Lipopolysaccharide In Early Pregnant Ewes As A Model To Study Bacterial Infection Induced Embryonic Loss, Jessalyn Marie Hadfield
Characterization Of The Immune Response To Lipopolysaccharide In Early Pregnant Ewes As A Model To Study Bacterial Infection Induced Embryonic Loss, Jessalyn Marie Hadfield
Graduate Theses, Dissertations, and Problem Reports (ETD)
An immunological balance has to be established during pregnancy that protects the mother yet tolerates the semi-allogenic fetus. To understand the innate immune response during bacterial infections that may cause early embryonic loss, a lipopolysaccharide (LPS) treated sheep model was used. Two objectives of this study were to examine if omega-3 PUFAs in the form of supplementary whole flaxseed could reduce the inflammatory response to an LPS challenge and to examine if there is a differential immune response to LPS in Suffolk and Dorset ewes. A total of 3 experiments were conducted; two investigating the effect of supplement and one …
Brook And Brown Trout Movement In A Restored Appalachian Watershed, Benjamin Joseph Harris
Brook And Brown Trout Movement In A Restored Appalachian Watershed, Benjamin Joseph Harris
Graduate Theses, Dissertations, and Problem Reports (ETD)
Understanding the localized ecological impacts of large-scale environmental (i.e., land use and climate) change is of critical importance not only to scientists tasked with natural resource management, but also individuals and communities across the world. In the Appalachian Mountains of the eastern United States, Brook Trout Salvelinus fontinalis serve as a key indicator species for the integrity of stream habitats. Brook Trout populations have largely declined throughout their native range, with impending climate change and thermal habitat exclusion potentially reducing Brook Trout habitat by more than 50%. Therefore, it is imperative that we understand interactions between Brook Trout and the …

Geographic Biases In Human Lyme Disease Surveillance And Utility Of Companion Animal Sentinel Programs: Exploratory Spatial Analysis, Brian Hendricks
Graduate Theses, Dissertations, and Problem Reports (ETD)
Background and Objectives: Mapping and exploratory spatial data analyses are ideal tools for characterizing spread and occurrence of human Lyme disease infection. Unfortunately, many mapped displays utilizing Lyme disease surveillance data are prone to bias due to a lack of consideration for geographical confounders. The objectives of our study were to 1) characterize the geographic effects that boundary and travel related biases have on visualization of human Lyme disease occurrence and 2) apply these findings to develop a more precise methodology for evaluating efficacy of animal sentinel surveillance programs in predicting incidence of human Lyme disease infection.;Methods: County-level human Lyme …
