The Application Of Chitosan On An Experimental Infection Of Pseudogymnoascus Destructans Increases Survival In Little Brown Bats, Torin C. Kulhanek

Masters Theses

This research builds upon a previous study conducted that tested the efficacy of chitosan on experimentally-infected bats as a laboratory model of White-nose syndrome. White-nose syndrome is a fungal infection caused by Pseudogymnoascus destructans, formerly known as Geomyces destructans. The pathology of this disease is not yet fully understood, but it is devastating bats throughout Northeastern America and continues to spread. Here we tested multiple application time points and concentrations of chitosan on the wings of experimentally-infected bats and compared them with the controls. We grossly viewed the wings first to get a sense of the amount of …

The Oncolytic Potential Of Tanapoxvirus To Treat Retinoblastoma, John D. Christie

Masters Theses

Retinoblastoma is the leading cause of intraocular malignancy in children under 2 years of age. Current treatments, while generally effective in eliminating the tumor, have many negative side effects. Oncolytic virotherapy is the use of either wild type or recombinant viruses, to destroy tumor cells. There are currently several viruses being engineered as potential therapeutics for a wide range of cancers. They offer tumor specific alternative to current therapies with lesser toxicity. This study looked at the oncolytic efficacy of multiple tanapoxviruses (TPV) recombinants in an in vitro retinoblastoma. Here we have tested recombinants of TPV for their ability to …

Fecal Bacterial Communities As An Indicator Of Trophic Interactions Among Anuran Larvae, Steven Jacob Everman

Master's Theses

Anurans are mass spawners, often with multiple females spawning together, resulting in thousands of tadpoles sharing a habitat. Such large numbers of tadpoles with limited dispersal can lead to intense competition for resources. Inter and intra-specific competition for food could have negative impacts on the growth and survival of smaller tadpoles. Fecal bacterial communities have the potential to be used as indicators of changes in diet making it possible to determine if tadpoles in the wild are eating the same food or not. After feeding on two prepared diets that differed in the percentage of complex carbohydrates, the fecal bacterial …

Possible Past Hybridization Among Desmognathus Ochrophaeus In Canadice Lake: An Ecological Survey Exploring Desmognathine Salamanders And The Competitive Exclusion Hypothesis In The Western Finger Lakes Of New York State, Aisha L. Gadson

Theses

Dusky Salamanders are a varied group of sister taxa found in Northeastern North America. Two species, Desmognathus fuscus and Desmognathus ochrophaeus, have geographically overlapping ranges. In addition, they are very morphologically similar, share many niche requirements, and are found in extremely similar or even the same salamander communities. These shared traits have been posited to arise from the influence of niche conservatism during their species’ evolutions. Also, despite their physical similarities they are historically found not to hybridize on a large scale, nor have ever had a full population merge recorded. Therefore, it appears that the community ecology of these …

Thesis Inquiry & Process: Something About Reality, Blayke Mackenzie Morrow

Theses

This thesis documents the employment of a system of Process and Inquiry as it serves as a structural foundation for an investigation of the manner in which Reality is represented in visual portraiture. Through a vigorous exploration of the concept of Reality and its singular nature, it is hypothesized that intrinsically unique experiences could potentially be communicated through the perceptive abilities of the emotional quotient. The effects of media, timing, complexity, abstraction, and authenticity are examined for their effect on the apparent clarity of concepts transmitted in this manner. The inquiry ultimately manifests in the daily creation of self-portraiture, as …

The Uncanny Valley The Effect Of Removing Blendshapes From Facial Animation, Ameya Lonkar

Theses

Ever since its introduction in 1970 by the roboticist Dr. Mori, the uncanny valley has become an integral part of facial animation. While most of the work on the uncanny valley is focused on finding a way to surpass the uncanny valley and how certain things could be designed to increase or decrease the uncanniness of an animation, this paper investigates how removing certain blendshapes from the facial animation changes our perception about the eeriness of that animation. The goal is to identify the “necessary” blendshapes which bring about a significant change the perceived uncanniness of the animation. For achieving …

Heart Valve Mathematical Models, Paula Kolar

Theses

Nearly 100,000 heart valve replacements or repairs are performed in the US every year. Mathematical models of heart valves are used to improve artificial valve design and to guide surgeons performing valve-repairing surgeries. Models can be used to define the geometry of a valve, predict blood flow dynamics, or demonstrate operating mechanisms of the valve. In this thesis we reviewed features that are typically considered when developing a model of a heart valve. The main modeling methods include representing a heart valve using lumped parameters, finite elements, or isogeometric elements. Examples of a lumped-parameter model and isogeometric analysis are explored. …

Actuation Of An Inertia-Coupled Rimless Wheel Model Across Level Ground, Seth Caleb Weeks

Theses

The inertia-coupled rimless wheel model is a passive dynamic walking device which is theoretically capable of achieving highly efficient motion with no energy losses. Under non-ideal circumstances, energy losses due to air drag require the use of actuation to maintain stable motions. The Actuated Inertia-coupled Rimless Wheel Across Flat Terrain (AIRWAFT) model provides actuation to an inertia-coupled rimless wheel model across level ground to compensate for energy losses by applying hip-torque between the frame and inertia wheel via a motor. Two methods of defining the open-loop actuation are presented. Position control defines the relative position of the drum relative to …

Master's Theses

Critical spawning and feeding habitat was designated for federally threatened, anadromous Gulf Sturgeon (GS) to aid in population recovery. This study examined GS occupancy, habitat use, and movement through critical habitat monitored by the Ship Island (SI) acoustic array during overwintering periods from 2011 to 2015 prior to MsCIP SI restoration. An occupancy index analyzed patterns of spatial and temporal habitat use of both western and eastern population segments (WPS and EPS, respectively) of GS on the SI array. The ends of SI along with the passes and cuts of the island, especially Dog Keys Pass (DKP), were occupied by …

The Elasmobranch-Microbe Relationship: Trimethylamine N-Oxide Synthesis, Urea Hydrolysis, And Microbe-Osmolyte Interactions In The Atlantic Stingray, Dasyatis Sabina, Kaitlin Kelly Doucette

Master's Theses

The elasmobranch osmoregulatory strategy is predicated on the accumulation of nitrogenous compounds, primarily urea and trimethylamine n¬-oxide (TMAO). Despite the abundance of these plasma osmolytes, it is notable that elasmobranchs appear to lack urease and TMA oxidase (Tmase), enzymes that scavenge urea-nitrogen and synthesize TMAO, respectively. However, urease and Tmase are found in many species of bacteria. Therefore, I hypothesized that intestinal bacteria are responsible for urease and Tmase activity in elasmobranchs. Absent dietary nitrogen sources, I evaluated the effects of reduced intestinal microbiota on osmoregulation in Atlantic stingray (Dasyatis sabina) in vivo. D. sabina were given …

Bloom Or Bust: Retrospective Analysis Of The Giant Jellyfish, Nemopilema Nomurai (Scyphozoa: Rhizostomeae), Ecology In The East Asian Marginal Seas, Naomi Yoder

Master's Theses

The Giant Jellyfish, Nemopilema nomurai, is a large-bodied bloom-forming jellyfish that occurs in the semi-enclosed basins of the East Asian Marginal Seas. N. nomurai has bloomed more frequently in the past 20 years than in any period previously recorded. In Japan, recent N. nomurai blooms were responsible for millions of dollars in lost revenue and equipment damage to commercial fisheries alone. This study statistically analyzed 21 environmental factors in connection with N. nomurai occurrence (using occurrence as a proxy for blooms). Eight factors resulted in a statistically significant or marginally significant (p ≤ 0.10), linear or non-linear relationship with …

Three-Dimensional Analysis Of The Development Of Upper Arm Musculoskeletal Stress Markers In Late Adolescents And Young Adults Of Archaic And Mississippian Populations Of Tennessee, Heather Marie Guzik

Master's Theses

This study compares three methods for the evaluation of morphology of musculoskeletal attachment sites. Two methods were macroscopic and the third was microscopic, utilizing three-dimensional laser scanning and fractal analysis The morphology of 19 upper limb attachment sites was observed in 33 males aged 15 and 30+ years, dating to the Archaic and Mississippian periods from the southeastern U.S. It was hypothesized that 1) the microscopic method would identify subtler differences than the macroscopic methods; 2) enthesis development would be greater in the Mississippian population due to the increased subsistence workload, even among younger individuals; and 3) late adolescents would …

Black-White Disparities In Criminal Justice Referrals To Drug Treatment: Addressing Treatment Need Or Expanding The Diagnostic Net?, Karen Mcelrath, Angela Taylor, Kimberly K. Tran

College of Humanities and Social Sciences

Slightly more than half of admissions to U.S. publicly-funded treatment for marijuana use are referred by the criminal justice system; this pattern has remained for at least 20 years. Nationally, Blacks comprise nearly a third of treatment admissions for marijuana use. This article explores the interplay between race and criminal justice referrals to treatment for marijuana use. Using data from the (U.S.) 2011 Treatment Episode Data Set, we examine the relationship between race and diagnosis of cannabis use disorder (dependence versus abuse) among referrals to community-based treatment in North Carolina. We compare Black/White differences in cannabis diagnoses across four referral …

The poets are Alice Dunbar Nelson, Clarissa Scott Delany, Gwendolyn Bennett, Langston Hughes, Arna Bontemps, Countee Cullen, and Helene Johnson. A few of them were a part of the core group that spurred this powerful movement. The Harlem Renaissance was a flourishing time in American history when African Americans felt …

Dishonest Ethical Advocacy?: False Defenses In Criminal Court, Joshua A. Liebman

Fordham Law Review

This Note examines this dilemma and recent judicial approaches to it. Judges disagree about how guilty criminal defendants should be permitted to mount defenses at trial. Some have forbidden defense counsel from knowingly advancing any false exculpatory proposition. Others have permitted guilty defense attorneys to present sincere or truthful testimony in order to bolster a falsehood. And still others have signaled more general comfort with the idea that an attorney aggressively can pursue an acquittal on behalf of a guilty client. This Note seeks to resolve this issue by parsing the range of false defense tactics available to attorneys and …

Consumer Likelihood To Complain In The U.S. Commercial Airline Industry, Xinpei Lu

Theses and Dissertations

Consumer emotions play an important role in the marketplace nowadays, which can either directly or indirectly affect the marketing outcomes. Consumer complaints are believed to occur if consumers begin to generate negative emotions due to an unfavorable service experience. However, there are also existing controversies. Moreover, males and females tended to show different attitudes towards complaining in different situations. There is a great significance of doing the research of consumer complaints in commercial airline industry because a majority of the predominant research concentrates on the consumer complaint behaviors in market places such as restaurant, hospital, hotel, and shopping mall. The …

A Further Analysis Of Commission Errors During Discrete Trial Training, Tavy Alisa Matthews

Theses and Dissertations

Treatment integrity has been manipulated in various ways to evaluate its impact on intervention effectiveness. Studies have compared different types of integrity failures and levels of treatment integrity in various contexts and behavioral interventions. Evaluations include differential reinforcement of alternative behavior, child compliance, and discrete trial training. However, further research is needed to establish the point at which integrity becomes detrimental to intervention effectiveness. The purpose of this study was to conduct a parametric analysis (i.e., 100%, 75%, 50%, & 25%) of treatment integrity to examine the effects of commission errors during discrete trial training. Three participants, ages 35 - …

Phytotoxicity Of Silver Species To Egeria Densa And Applications To Phytoremediation, Leonard James Bernas

Theses and Dissertations

Silver species pose a significant threat to aquatic ecosystems because the use of silver nanoparticles (AgNps) for industrial applications is significantly increasing, as are discharges into waterways. The effects have only been studied on select fish and aquatic plants, so more research is needed to understand the risks associated with silver species in the environment. Egeria densa (E. densa, also known as Elodea densa), a common freshwater submerged macrophyte, was exposed to 0-1.25 ppm silver cations and 2 and 15 nm AgNps in an aqueous environment for 7 days. E. densa was chosen for this study because it is a …

Categorizing “Muck” In The Indian River Lagoon, Florida, Based On Chemical, Physical And Biological Characteristics, Katherine Mae Beckett

Theses and Dissertations

During the past six decades, the thickness and areal extent of muck sediments have continually increased in the Indian River Lagoon (IRL), Florida. These sediments are anoxic, store and release nutrients, and destroy natural benthic habitats. The main objective of this research was to develop guidelines that help prioritize sites for muck removal based on the following: (1) biological abundance and diversity, (2) muck thickness, and (3) the physical and chemical composition of muck. Thinner muck deposits (20-40 cm), collected during two seasons at eight locations in the lagoon and adjacent creeks, had greater variability in sediment composition and ~5 …

Soteria: A Persuasive Esecurity Assistant, Punica Bhardwaj

Theses and Dissertations

“…security is only as good as the weakest link, and people are the weakest link in the chain.” – B Schneier, 2002 Humans are often referred to as the “weakest link” in the security chain because of the poor security decisions taken by them. There can be many reasons for these decisions, such as lack of understandability of the software, lack of education, and lack of relevant information required to do that particular action. In this Thesis, we focus on the lack of relevant information required at the time of performing the action. In order to provide the user with …

The Tolerance Of Benthic Infauna To Fine-Grained Organic Rich Sediments In A Shallow Subtropical Estuary, Daniel Christopher Hope

Theses and Dissertations

Fine-grained organic-rich sediments (FGORS) from anthropogenic impacts are a growing concern for bays and estuaries around the world. This study explores the relationships between infaunal community diversity and species’ abundances with FGORS in the Indian River Lagoon and its tributaries. To examine these potential relationships, infauna were collected monthly using a Petit Ponar grab at 16 stations in the central Indian River Lagoon from October 2015 to August 2016. Abundant taxa in these sediments include polychaete worms (e.g., the polychaete Nereis succinea), molluscs (e.g., clam Parastarte triquetra), and arthropods (e.g., the tanaid Leptochelia dubia) with densities as high as 5.3x10⁴ …

Draft Genome Of The Leopard Gecko, Eublepharis Macularius, Zijun Xiong, Fang Li, Qiye Li, Long Zhou, Jiao Zheng, Tony Gamble, Ling Kui, Cai Li, Shengbin Li, Huanming Yang, Guojie Zhang

Biological Sciences Faculty Research and Publications

Background

Geckos are among the most species-rich reptile groups and the sister clade to all other lizards and snakes. Geckos possess a suite of distinctive characteristics, including adhesive digits, nocturnal activity, hard, calcareous eggshells, and a lack of eyelids. However, one gecko clade, the Eublepharidae, appears to be the exception to most of these ‘rules’ and lacks adhesive toe pads, has eyelids, and lays eggs with soft, leathery eggshells. These differences make eublepharids an important component of any investigation into the underlying genomic innovations contributing to the distinctive phenotypes in ‘typical’ geckos.

We report high-depth genome sequencing, assembly, and …

The Effect Of Squid Extract (Loligo Sp) On Tnf-Α And Tgf-Β1 Serum Levels During Wound Healing In Streptozotocin-Induced Diabetic Rats, Kadek Np Dewi, Heri Kristianto, Mochamad R. Indra

Makara Journal of Health Research

Background: Diabetes Mellitus is a chronic disease characterised by elevated levels of blood glucose known as hyperglycaemia. Diabetes is due to impaired insulin action in the metabolism of glucose and can result in impaired wound healing. Excessive production of pro-inflammatory cytokines, an increased number of macrophages and neutrophils, and decreased levels of transforming growth factor - beta 1 (TGF-β1) serum can be characteristic of impaired wound healing. This study aims to determine the effects of squid extract on certain wound parameters such as levels of tumour necrosis factor - alpha (TNF-α), and TGF-β1 serum and the number of macrophages and …

Computational Circuit For Use In Real Time Color Amplification, Andrew Yokubaitis, Vinayak Pandu Raju

Electrical Engineering

The Eulerian Video Amplification algorithm developed at MIT allows for amplification of very small changes in seemingly static video scenes. The algorithm helps visualize these small changes by amplifying them to pull out signals of interest, such as the human pulse and the motion of hot air. This algorithm is computationally intensive and, as is, is difficult to run in real-time as a serially executed program. Our project is to design a parallel processing circuit that allows the algorithm to be calculated in hardware in order to magnify these small changes in real time. This will be done by using …

A Biologically Active Tnf-Alpha Inhibitor Fails To Suppress Colitis In Balb/C Mice, Stephanie E. Biel

Graduate Theses/Dissertations

Tumor necrosis factor a (TNFα), a potent inflammatory cytokine, has long been established as a major driving force for pathologic inflammation. Currently, anti-TNFα therapies are the standard in Inflammatory Bowel Disease (IBD) management; however, one-third of IBD patients fail to respond to anti-TNFα therapies. Previous data from this lab indicate that TNFα Converting Enzyme (TACE) inhibition does not ameliorate colitis in BALB/C mice. Thus, we hypothesized that TNFα is not a critical component in the BALB/C model of colitis. To test this, acute colitis was induced in BALB/C mice by consumption of 5% dextran sulfate sodium (DSS) in drinking water …

Effect Of A Short-Term Field Experience On Student Outdoor Environmental Knowledge, Comfort Levels, Attitude, And Action Scores, Brandi Niccole Silvey

Graduate Theses/Dissertations

Many children today may not be familiar with nature due to lack of experience and education in the outdoors. If they are not exposed to nature, then they will not be as comfortable in the outdoors. This study evaluates the effectiveness of educational activities at the Watershed Center in Springfield, Missouri on high school students' and college level pre-service teachers' knowledge, comfort levels, attitudes, and actions toward the outdoor environment. Post-field trip responses of students who came to the Watershed Center were compared to students who did not participate in a field trip. Teachers were also surveyed to assess why …
