Dust Emission From South Dakota Cattle Feedlots, Rick Weber

The Journal of Undergraduate Research

Dust and particle emissions (PM) from cattle feedlots is a concern for producers in order to maintain good relations with neighbors and also to comply with the EPA proposed PM_2.5 particulate emission rules. Dust at 2.5 microns, which cannot be seen by the naked eye, is a potential health hazard since it can be ingested into the lungs of humans. One of the proposed regulations of the Federal Clean Air Act is to apply the PM_2.5 standard to the agricultural sector. This research project examines the particulate matter dust emissions of various sizes in microns including 2.5, 10, …

The Dangerous Quest For Nature Narratives In Goethe’S Werther: A Reading Of The Ruptured Monologue And The Ruptured Body, Heather I. Sullivan

Modern Languages and Literatures Faculty Research

Assessing Goethe's narrative ruptures, this essay follows their trail in three directions: first through the editor's sudden interruption of Werther producing the post-epistolary multiplicity of voices, second in the alterations Goethe made to the 1787 version of Werther that enhance the theme of rupture itself, and third along the fault-lines delineated in three exemplary "letters of nature" from Werther.

Role Of Calcium And Nitric Oxide Synthase (Nos) In Brain Mitochondrial Dysfunction, Vidya Nag Nukala

Theses and Dissertations--Neuroscience

Mitochondria are essential for promoting cell survival and growth through aerobic metabolism and energy production. Mitochondrial function is typically analyzed using mitochondria freshly isolated from tissues and cells because they yield tightly coupled mitochondria, whereas those from frozen tissue can consist of broken mitochondria and membrane fragments. A method, utilizing a well-characterized cryoprotectant such as dimethyl sulfoxide (DMSO), is described. Such mitochondria show preserved structure and function that presents us with a possible strategy to considerably expand the time-frame and the range of biochemical, molecular and metabolic studies that can be performed without the constraints of mitochondrial longevity ex vivo …

Functional Properties Of L-Glutamate Regulation In Anesthetized And Freely Moving Mice, Kevin N. Hascup

Theses and Dissertations--Neuroscience

L-glutamate (Glu) is the predominant excitatory neurotransmitter in the mammalian central nervous system with involvement encompassing learning and memory, cognition, plasticity, and motor movement. Dysregulation of the glutamatergic system is implicated in several neurological disorders including Parkinson’s disease, Alzheimer’s disease, Huntington’s disease and amyotrophic lateral sclerosis. The mechanisms underlying these neurological disorders are not clear, but evidence suggests that abnormal Glu neurotransmission plays a role. Elevated levels of Glu in the synaptic cleft overstimulate the N-methyl-Daspartate receptor leading to excitotoxicity, which causes neuronal loss in chronic neurological diseases. What is less understood is the source for the elevated Glu levels. …

Xenobiotic Transporters In Lactating Mammary Epithelial Cells: Predictions For Drug Accumulation In Breast Milk, Philip Earle Empey

Theses and Dissertations--Pharmacy

Recent literature has established that breast cancer resistance protein (ABCG2) is upregulated during lactation and is responsible for the greater than predicted accumulation of many drugs in breast milk. The objectives of this project were (1) to investigate the role of this transporter in the reported apically-directed nitrofurantoin flux in the CIT3 cell culture model of lactation, (2) to develop a mathematical model for drug transfer into breast milk to relate initial flux rates, steady-state concentrations, efflux ratios, and in vivo milk to serum ratios (M/S) and (3) to identify xenobiotic transporters that are highly expressed, and therefore potentially important …

The Role Of Macrophages In Olfactory Neurogenesis, Aaron S. Borders

Theses and Dissertations--Physiology

Olfactory sensory neurons (OSNs) undergo continual degeneration and replacement throughout life, a cycle that can be synchronized experimentally by performing olfactory bulbectomy (OBX). OBX induces apoptosis of mature OSNs, which is followed by an increase in the proliferation of progenitor basal cells. Macrophages, functionally diverse immune effector cells, phagocytose the apoptotic OSNs and regulate the proliferation of basal cells. This provides an advantageous environment to study how macrophages regulate neuronal death, proliferation, and replacement.

The purpose of this dissertation was to identify the cellular and molecular mechanisms by which macrophages regulate the degeneration/proliferation cycle of OSNs. Macrophages were selectively depleted …

Beyond Westphalia: Competitive Legalization In Emerging Transnational Regulatory Systems, Errol E. Meidinger

Contributions to Books

Published as Chapter 7 in Law and Legalization in Transnational Relations, Christian Brütsch & Dirk Lehmkuhl, eds.

This paper analyzes several emerging transnational regulatory systems that engage, but are not centered on state legal systems. Driven primarily by civil society organizations, the new regulatory systems use conventional technical standard setting and certification techniques to establish market-leveraged, social and environmental regulatory programs. These programs resemble state regulatory programs in many important respects, and are increasingly legalized. Individual sectors generally have multiple regulatory programs that compete with, but also mimic and reinforce each other. While forestry is the most developed example, similar …

A Matter Of Marching, A Matter Of Supply: Politics And Logistics In Arkansas, 1863-1864, Alfred Hoyt Wallace

Graduate Theses/Dissertations

In the spring of 1864, Major General Frederick Steele led his men out of Little Rock on orders to cooperate with Major General Nathaniel Banks's campaign up the Red River. The two forces never met as planned. Steele eventually captured Camden, Arkansas, but was obliged to retreat in the face of a determined Confederate force approaching him. The Camden Expedition, as this became known, has typically been cast as an expedition that failed due to a severe shortage of available food along the line of march. Upon closer investigation, however, particularly in the records of common soldiers, a different explanation …

On The Incorporation Of The Personality Factors Into Crowd Simulation, Sivakumar Jaganathan

Electronic Theses and Dissertations

Recently, a considerable amount of research has been performed on simulating the collective behavior of pedestrians in the street or people finding their way inside a building or a room. Comprehensive reviews of the state of the art can be found in Schreckenberg and Deo (2002) and Batty, M., DeSyllas, J. and Duxbury, E. (2003). In all these simulation studies, one area that is lacking is accounting for the effects of human personalities on the outcome. As a result, there is a growing emphasis on researching the effects of human personalities and adding the results to the simulations to make …

Pilot Study Of Nutrient Loading In A Wet Detention Lake, Eric C. Gurr

Electronic Theses and Dissertations

Florida is surrounded by water, and its many internal lakes and rivers have long been recognized for their excellent fishing and boating. This notoriety draws land developers to the lake shores to establish residential and commercial infrastructure. This land development brings with it flood plain alteration, water level stabilization, and increased nutrients which cause adverse impacts to our lakes. In response, the United States Environmental Protection Agency (EPA) passed the Federal Clean Water Act (CWA) in 1972 which set the framework for the water quality standards for the entire United States. As a result of the CWA many point sources …

Examining Dynamic Variable Speed Limit Strategies For The Reduction Of Real-Time Crash Risk On Freeways, Ryan Cunningham

Electronic Theses and Dissertations

Recent research at the University of Central Florida involving crashes on Interstate-4 in Orlando, Florida has led to the creation of new statistical models capable of determining the crash risk on the freeway (Abdel-Aty et al., 2004; 2005, Pande and Abdel-Aty, 2006). These models are able to calculate the rear-end and lane-change crash risks along the freeway in real-time through the use of static information at various locations along the freeway as well as the real-time traffic data obtained by loop detectors. Since these models use real-time traffic data, they are capable of calculating rear-end and lane-change crash risk values …

Discussion On Effective Restoration Of Oral Speech Using Voice Conversion Techniques Based On Gaussian Mixture Modeling, Gustavo Alverio

Electronic Theses and Dissertations

Today's world consists of many ways to communicate information. One of the most effective ways to communicate is through the use of speech. Unfortunately many lose the ability to converse. This in turn leads to a large negative psychological impact. In addition, skills such as lecturing and singing must now be restored via other methods. The usage of text-to-speech synthesis has been a popular resolution of restoring the capability to use oral speech. Text to speech synthesizers convert text into speech. Although text to speech systems are useful, they only allow for few default voice selections that do not represent …

Dynamic Speed Monitoring System Effectiveness On Sharp Curves, Vasu Tavasna Persaud

Electronic Theses and Dissertations

The design of rural interchanges is of critical concern due to the need for the safe transition of vehicles from one high speed roadways to another and vice versa. This transition is accomplished by entry and exit ramps of various forms. The southbound entry loop ramp at the US 27/ US 192 trumpet interchange in Polk County, Florida does not provide such safe transition since historically there has been a high incidence of vehicular off-tracking. The geometry of the southbound entry ramp coupled with high approach speeds are two of the contributing factors. Due to the high cost of interchange …

Optimizing The Design Of Multimodal User Interfaces, Leah Reeves

Electronic Theses and Dissertations

Due to a current lack of principle-driven multimodal user interface design guidelines, designers may encounter difficulties when choosing the most appropriate display modality for given users or specific tasks (e.g., verbal versus spatial tasks). The development of multimodal display guidelines from both a user and task domain perspective is thus critical to the achievement of successful human-system interaction. Specifically, there is a need to determine how to design task information presentation (e.g., via which modalities) to capitalize on an individual operator's information processing capabilities and the inherent efficiencies associated with redundant sensory information, thereby alleviating information overload. The present effort …

Cognitive Learning From Computer-Based Information Systems By Incorporating Knowledge Construction Interventions, Wajdi Wazzan

Electronic Theses and Dissertations

The aim of the present study was to develop and empirically evaluate different categories of instructional activities, which stimulate the generation and construction of knowledge on the part of an individual student. These generative activities are primed by prompts or scaffolds, which can easily be inserted into specific curriculum addressing any domain of knowledge. To assess the manner in which the knowledge construction interventions influence the learning outcomes from computerized information systems, we have developed an online computer-based information system that describes the functions and mechanisms associated with the bus system of the US army Abrams M1A2 tank. Seven versions …

Cost-Benefit Analysis Without Analyzing Costs Or Benefits: Reasonable Accommodation, Balancing, And Stigmatic Harms, Cass R. Sunstein

Public Law and Legal Theory Working Papers

Is an accommodation “reasonable,” under the Americans with Disabilities Act, if and only if the benefits are roughly proportional to the costs? How should benefits and costs be assessed? Should courts asks about how much disabled employees are willing to pay to obtain the accommodation, or instead how much they would have to be paid not to have the accommodation? How should stigmatic or expressive harms be valued? This essay, written for a symposium on the work of Judge Richard A. Posner, engages these questions in a discussion of an important opinion in which Judge Posner denied accommodations involving the …
