Graduate Theses, Dissertations, and Problem Reports (ETD)

Background and Objectives: Correct tooth position in all planes of space while respecting the boundaries of the underlying bone has been proposed as a necessary hallmark to providing a foundation of stability for the teeth as well as the supporting periodontium. The aim of this study was to determine 1) If teeth centeredness over basal bone improves when teeth are more upright or approach WALA Ridge norms 2) If teeth centeredness in alveolar bone improves when teeth are more upright or approach WALA Ridge norms 3) If the WALA ridge is located at or near the estimated center of resistance …

Role For Protein Prenylation And "Caax" Processing In Photoreceptor Neurons, Nachiket D. Pendse

Graduate Theses, Dissertations, and Problem Reports (ETD)

The efficient folding, assembly and trafficking of phototransduction proteins from site of synthesis in the inner segment (IS) to the site of action in the outer segment (OS) is crucial for photoreceptor cell survival and function. Defects in this process are known to cause blinding diseases in humans including retinitis pigmentosa (RP) and Leber's congenital amaurosis (LCA). The lack of a therapeutic approach for treatment of various retinal degenerations is likely due a knowledge gap in the mechanisms underlying the folding, assembly and transport of prenylated phototransduction proteins. Prenylation and " CAAX" processing is thought to be involved not only …

Grainyhead-Like-2 Inhibits The Co-Activator P300, Suppressing Tubulogenesis And The Epithelial-Mesenchymal Transition, Phillip M. Pifer

Graduate Theses, Dissertations, and Problem Reports (ETD)

Tumor progression and developmental morphogenesis require transient or stable Epithelial-Mesenchymal transitions (EMT) to modulate epithelial junctional complexes allowing programmed migration, invasion, and anoikis resistance of cells. Grainyhead-like-2 (GRHL2), an epithelial master-regulatory transcription factor, suppresses EMT and causes a mesenchymal-epithelial transition to the default epithelial phenotype. This body of work investigates the role of GRHL2 in kidney cancer, in kidney development using a kidney specific GRHL2 knockout mouse model, and in tubulogenesis using Madin-Darby Canine Kidney (MDCK) cells. In kidney cancer, GRHL2 was not expressed in the normal kidney proximal tubule epithelial cells which are thought to be the progenitors of …

Treatments included high or low mixer-added fat (2.5 vs. 0.5%), high or low distillers dried grains with solubles (DDGS) (8 vs. 2%), high or low dicalcium phosphate (1.63 vs. 0.31%), and high or …

Drawing On The Victorians: The Palimpsest Of Victorian And Neo-Victorian Graphic Texts, Anna Maria Jones, Rebecca N. Mitchell

Ohio University Press Open Access Books

Late nineteenth-century Britain experienced an unprecedented explosion of visual print culture and a simultaneous rise in literacy across social classes. New printing technologies facilitated quick and cheap dissemination of images—illustrated books, periodicals, cartoons, comics, and ephemera—to a mass readership. This Victorian visual turn prefigured the present-day impact of the Internet on how images are produced and shared, both driving and reflecting the visual culture of its time.

From this starting point, Drawing on the Victorians sets out to explore the relationship between Victorian graphic texts and today’s steampunk, manga, and other neo-Victorian genres that emulate and reinterpret their predecessors. Neo-Victorianism …

Impact Of Reduced Tillage And Crop Residue Management On Soil Properties And Crop Yields In A Long-Term Trial In Western Kenya, Jeremiah M. Okeyo, Jay Norton, Saidou Koala, Boaz Waswa, Job Kihara, Andre Bationo

All Peer-Reviewed Publications

Sustainable farming practices are required to address the persistent problems of land degradation and declining crop productivity in Sub-Saharan Africa. Approaches such as reducing tillage and retaining crop residues as mulch are potential entry points for smallholder farmers to move towards sustainability. In this study, we assessed the impact of reduced tillage (RT) compared with conventional tillage (CT), each combined with crop residue reapplication, on soil quality indicators and crop yields under an 8-year trial in western Kenya. Our results indicate that RT combined with crop residue reapplication enhanced soil physical quality through increased macroaggregate (>2000μm) proportions and mean …

High Sensitivity Sol-Gel Silica Coated Optical Fiber Sensor For Detection Of Ammonia In Water, Dejun Liu, Wei Han, Arun Mallik, Jinhui Yuan, Chongxiu Yu, Gerald Farrell, Yuliya Semenova, Qiang Wu

Articles

A high sensitivity ammonia sensor based on a tapered small core singlemode fiber (SCSMF) structure for measurement of ammonia concentration in water is reported. Two tapered SCSMF fiber structures with different waist diameters of 23 µm and 13.5 µm are fabricated by using a customized microheater brushing technique. The silica based material prepared by the sol-gel method is used as a coating applied to the surface of the tapered fiber structures. To investigate the influence of the coating thickness on the sensitivity to ammonia in water, silica coatings with different thicknesses (2-pass and 8-pass coatings) are deposited on the surface …

The Importance Of Motivation, Weapons, And Foul Odors In Driving Encounter Competition In Carnivores, Maximilian L. Allen, Christopher C. Wilmers, L. Mark Elbroch, Julie M. Golla, Heiko U. Wittmer

Environment and Society Faculty Publications

Encounter competition is interference competition in which animals directly contend for resources. Ecological theory predicts the trait that determines the resource holding potential (RHP), and hence the winner of encounter competition, is most often body size or mass. The difficulties of observing encounter competition in complex organisms in natural environments, however, has limited opportunities to test this theory across diverse species. We studied the outcome of encounter competition contests among mesocarnivores at deer carcasses in California to determine the most important variables for winning these contests. We found some support for current theory in that body mass is important in …

Fasd, Verbal Comprehension And Maladaptive Behavior, Anthony Brian Athmann

Theses and Dissertations

A Fetal Alcohol Spectrum Diagnosis is comprised of various levels of physical

dysmorphia and behavioral and cognitive dysfunctions. Early identification and diagnosis is difficult, requires specially trained practitioners and often results in the delay of receiving necessary services. This is particularly true for those individuals living in

underserved rural areas. However, screening children with commonly used assessment

tools may help to more quickly identify children who have been prenatally exposed to

alcohol. The purpose of the present study was to contribute to the development of a

neurobehavioral profile of alcohol-exposed children through examining if relationship

Trash Matters: An Investigation Into The Current Waste Management And Recycling Strategies In Rural North Dakota And Foreseeable Solutions, Amy Densborn

Theses and Dissertations

Rural North Dakota is behind the times for establishing an economically and socially beneficial method for collecting recyclables from residents, and in some areas providing sustainable trash removal. As the waste stream continues to grow, so will the burdens on our landfills, our resources and our environment for generations to come. An even worse alternative to landfilling garbage is the use of burn barrels, which release dioxins into the local environment, settling on vegetation and waterways and further bio-accumulate in the food chain. Rural residents currently do not have conveniently located or affordable disposal options for household generated waste and …

Strengthened Knights: Masculinity In Sir Isumbras And El Libro Del Caballero Zifar, Ruth Mary Gripentrog

Theses and Dissertations

In this thesis, I examine the masculinities of the titular characters in Sir Isumbras and El Libro del Caballero Zifar [The Book of the Knight Zifar] through a lens of power in which masculinity is proven through the dominance over other men. Zifar and Isumbras must construct and prove their masculinities in a variety of circumstances; however, they differ significantly in their treatment of masculinity: Sir Isumbras extolls a compound masculinity, which the Zifar aims for one of consistency. I have chosen to focus on two of medieval Europe’s main Christian powers, and through a comparative analysis, their distinct masculinities …

Vulnerability Indices For Waterbodies Impacted By Theoretical Hydraulic Fracturing Spills Modeled Utilizing Gis, Isaac Simon

Theses and Dissertations

Hydraulic fracturing is a method used to extract oil or natural gas from unconventional sources. Within western North Dakota it is largely used to extract oil from the Bakken Formation since the low permeability of the Bakken shale makes conventional methods of oil extraction difficult. Hydraulic fracturing utilizes large volumes of frack fluid and this frack fluid is toxic to humans, animals including livestock, and vegetation including crops. Research is needed to provide a greater understanding of where frack fluid would travel if spilled, how much frack fluid could infiltrate into the soil, and how much frack fluid could impact …

Theses and Dissertations

The purpose of this research study was to explore perceptions of university faculty and jewelry industry professionals regarding the teaching of Computer Aided Design (CAD) and Computer Aided Manufacture (CAM) in a visual arts classroom. At the time of this study, there were mixed opinions about the teaching of CAD/CAM in the production of jewelry products, and there was limited literature available on this topic. With the use of CAD/CAM technologies, a jeweler emerges as potentially an artist and a design engineer who can apply creative and innovative principles to industrial design and manufacturing processes. Considering the impact of CAD/CAM …

Graphic Design Students’ Perceptions Of Using Apple Ipads To Create Sketches And Promote Idea Generation, Elizabeth Becker

Theses and Dissertations

Artists and designers typically utilize sketching during the early stages of the design process because it provides them with an opportunity to transfer ideas from their head onto paper, computer, or mobile device. Sketching is regarded by researchers in the field of design to be an essential part of the design process.

The existing research in this field is focused on comparing paper and pencil sketches with sketches completed on computers. There is a void in the literature examining sketching completed on mobile devices like the Apple iPad. Therefore, this study aimed to fill that void.

The purpose of this …

An Assessment Of The Influence Of Economic Drivers Of Land Use Change On Nitrate Concentrations In The Red River Of The North Basin, Brent Silvis Silvis

Theses and Dissertations

In recent years there have been dramatic increases in crop prices, which would be expected to have resulted in greater production of crops and increased nitrates in surface water from increased use of fertilizer. The objective of this study was to test the hypothesis that changing crop prices influence crop production and, consequently, water quality. To do this, the study intended to identify changes in crop cultivation within the Red River of the North Basin, assess whether these crops have contributed to nitrate concentrations and identify how nitrate concentrations would be influenced by alternative economic scenarios. Requisite data were obtained …

Cntf Potentiates Survival And Sprouting Of Axotomized Magnocellular Neurons, Kathryn E. Erickson

Theses and Dissertations

Ciliary neurotrophic factor (CNTF) is believed to promote neuronal sprouting and survival within the magnocellular neurosecretory system (MNS) by means of astrocyte activation following injury. When CNTF binds to its receptor complex, CNTF receptor alpha, located on the extracellular surface of the astrocyte, it initiates the Jak/STAT3 pathway. The activation of this pathway and the translocation of phosphorylated STAT3 (pSTAT3) to the nucleus is believed to lead to the release of multiple factors that act in a paracrine manner to influence survival and sprouting of MNS neurons. To confirm the ability of CNTF to activate the astrocyte, the three receptor …

A Hydrometeorological And Geospatial Analysis Of Precipitation Within The Glacial Ridge Wildlife Refuge Using The R2ain-Gis Tool, William John Mokry

Theses and Dissertations

Weather radar (radio detection and ranging) is a specialized meteorological tool used to sample and track meteorological objects. This tool is critical for meteorologists and public decision-makers to inform and provide for their constituents in a timely manner, often with the protection of lives and property on the line. With the application of using meteorological and geospatial data in the realm of geographic information systems (G.I.S.), the task of blending the two sciences to inhibit further research and dissemination of information occurs.

This study focuses on the creation and implementation of a new geospatial tool, the Radar and Rainfall Analyzed …

Characterization Of Two Surface Proteins From The Lyme Spirochete And Their Roles During Mammalian Infection, Robert Anthony Gaultney

Theses and Dissertations

Borrelia burgdorferi is an enigmatic bacterial pathogen that afflicts a large proportion of the world population as the causative agent of Lyme disease. The bacterium has a number of factors that promote virulence including a complex and dynamic array of extracellular proteins that can interact with various molecules of an infected host. One such molecule, fibronectin, is a key glycoprotein in the ECM of mammalian hosts with multiple characterized functions. B. burgdorferi encodes multiple known Fn-binding proteins, and has an additional putative protein BB0347 that may also bind Fn. Another protein, MlpJ, is homologous to a known hemin-binding protein, which …

Britain's First War With Kandy: Landscape, Violence, And Conquest In Colonial Sri Lanka, Elizabeth Anne Mjelde

Theses and Dissertations

Accounts of travel to Sri Lanka published during the period of British conquest (1796 through 1818) reveal a consistent yet problematic tendency: despite ongoing military conflict, visual artists constructed representations of the island as a peaceful and orderly place. The contradiction is heightened when travelers’ uniformly tranquil images of Sri Lanka are juxtaposed with documented acts of destruction to land and property, undertaken by troops during Britain’s first war with the inland kingdom of Kandy, a conflict which eventually led to the island’s complete colonization. The present study reconciles this contradiction through analysis of publications by each of five artists …

Not Your Business: Pedagogical Lessons Of Activist Resistance To Neoliberalism In Canadian Higher Education, Jorunn Thordarson

Theses and Dissertations

The growing power and permeation of neoliberal ideology across all facets of social life has been instrumental in promoting and orchestrating a shift among Canadian post-secondary institutions towards a reductive view of schooling at the expense of a more liberatory vision of education. The aim of this study was to examine the connections between power, education, and democracy in relation to the neoliberal restructuring of higher education in Canada, while simultaneously exploring discourses of resistance to neoliberal hegemony. Using critical discourse analysis, this study begins by establishing the promotion and naturalization of neoliberal ideology within the policy landscape of Canadian …

What Is (And Isn't) Healthism?, Jessica L. Roberts, Elizabeth W. Leonard

Georgia Law Review

What does it mean to discriminateon the basis of health status? Health can, of course, speak to a number of things, such as the length of our lives, our ability to perform mentally and physically, our need for health care, and our risk of injury and incapacity. But the mere relevance of a particular attribute does not mean that considering it should be legally permissible. This Article explores when differentiating on the basis of health is acceptable- perhaps even desirable-and, by contrast, when it is normatively problematic. While we acknowledge that differentiations on the basis of health status can be …

Victims Of Downing Street: Popular Pressure And The Press In The Stoddart And Conolly Affair, 1838-1845, Sarah E. Kendrick

Senior Independent Study Theses

During the summer of 1842, Emir Nasrullah of Bukhara, in what is now Uzbekistan, beheaded Lieutenant-Colonel Charles Stoddart and Captain Arthur Conolly, two British officers sent to his kingdom on a diplomatic mission. Reports of the officers’ deaths caused an uproar across Britain, and raised questions about the extent to which Britons abroad were entitled to government protection. Historians have generally examined the officers’ deaths exclusively in the context of the Great Game (the nineteenth century Anglo-Russian rivalry over Central Asia) without addressing the furor the crisis caused in England. By focusing too narrowly on the relevance of this crisis …

A total of 95 randomly chosen SLPs completed an online survey regarding their hearing technology training, their perceptions of the need for this type of training, and their clinical experiences working with hearing technology in educational settings. The types of hearing technology included hearing aids, cochlear implants, and FM/Infrared (IR) systems. Overall, participants reported a lack of sufficient hearing technology training and low comfort levels with performing hearing technology tasks, such …

Phonetic Shift /Ɔr/ Phonemic Change? American English Mergers Over 40 Years, Joseph A. Stanley, Margaret E. L. Renwick

Faculty Publications

In this paper we analyze the vowel formants of a speaker over four decades to show phonemic change through time. Other real-time studies (Harrington, Palethorpe & Watson 2000; Harrington & Reubold 2015) have found that the vowel spaces of UK English speakers shift over the lifetime, likely as a consequence of interaction with speakers of other dialects or social classes. We focus on an understudied variety of English, spoken in the western United States, to investigate a pair of phonological mergers, the cord-card merger and the hoarse-horse merger.

The cord-card merger is a result of a historical three-way contrast of …
