Christ The Redeemer And The Best Of All Possibly Created Worlds: Using Alvin Plantinga's 'O Felix Culpa' Theodicy As A Response To William Rowe's 'Can God Be Free?' And The Underlying Evidential Argument From Evil, P. Roger Turner

Masters Theses

In his "The Problem of Evil and Some Varieties of Atheism," William Rowe famously argues that there are no God justifying goods that we know of that can excuse God's allowing the very many widespread evils and horrors there are in our world. I argue that this forms the backbone of his 2004 volume entitled Can God be Free? in which he posits two further arguments: (1) God must create the best of necessity and is thereby not free and so not praiseworthy, and (2) God cannot create a best world (since there is no best) and so always does …

A Gpu-Based Implementation For Improved Online Rebinning Performance In Clinical 3-D Pet, Dilip Reddy Patlolla

Masters Theses

Online rebinning is an important and well-established technique for reducing the time required to process Positron Emission Tomography data. However, the need for efficient data processing in a clinical setting is growing rapidly and is beginning to exceed the capability of traditional online processing methods. High-count rate applications such as Rubidium 3-D PET studies can easily saturate current online rebinning technology. Realtime processing at these high-count rates is essential to avoid significant data loss. In addition, the emergence of time-of-flight (TOF) scanners is producing very large data sets for processing. TOF applications require efficient online Rebinning methods so as to …

Effect Of Selenium On Glucosinolate And Isothiocyanate Concentrations In Arabidopsis Thaliana And Rapid-Cycling Brassica Oleracea, Thomas Casey Barickman

Masters Theses

Brassica vegetables play a unique nutritional and sensory role in human diets around the world. Their characteristic flavors come from the break down products of glucosinolate (GS) compounds, a large group of nitrogen (N) and sulfur (S) containing glucosides. Glucosinolates are hydrolyzed by myrosinase to isothiocyanates (ITCs) which are biologically active. Mounting evidence of this process is of scientific interest due to the potential for high consumption of Brassica vegetables containing several GSs and their respective hydrolysis products that are associated with cancer chemoprevention. Glucosinolates are sulfur-rich hydrophilic, nonvolatile plant secondary metabolites; and. over the past few decades, their importance …

A Business Process Modeling Approach For Evaluating A Government Contract Closeout Process, Clayton Jerrett Capizzi

Masters Theses

This thesis examines the practice of Business Process Modeling (BPM) in the field of contracts management. Government defense contractors are heavily burdened by contracts which have ended, but have not been finalized and closed. In order to keep good relations with organizations regulating government contracts, contractors have been forced to devise a strategy to address contract closeouts. Through utilization of BPM practices, an organization is able to not only model the flow of their contract closeout process, but simulate the performance of their process under varying conditions so that goals and deadlines may be met. Data was collected about a …

Calcitriol And The Renin Angiotensin System, And Adipose Tissue Inflammation, Christina Marie Caserio

Masters Theses

Adipose tissue is well recognized as an endocrine organ and a source of proinflammatory molecules ¹. We recently demonstrated calcitriol stimulates adipocte reactive oxygen species (ROS) production and inflammatory stress (IS), while dietary calcium suppression of calcitriol exerted the opposite effect. These effects are mediated, in part, by calcitriol modulation of intracellular calcium (Ca²⁺) signaling and mitochondrial potential. However, adipocytes contain a functional RAS, and angiotensin II (ANGII) modulates ROS and IS. Accordingly, we investigated the role of ANGII in mediating calcitriol effects. Calcitriol (1 nM) stimulated NOX4 expression and ROS production in 3T3-L1 adipocytes by 67% …

Development Of A Novel Lysophosphatidic Acid Activity Probe To Identify And Characterize New Protein Targets, Leah M. Cuthriell

Masters Theses

Lipids are categorized according to their biological function. Phospholipids, glycolipids, and cholesterol are bulk membrane lipids that offer structure and support to the cells and organelle membranes. Signaling lipids include diacylglycerol, phosphatidic acid, and lysophosphatidic acid (LPA). These are low abundance lipids that are active in various pathways. LPA acts through GPCR receptors to activate G or beta mediated stimulation of phospholipase C leading to phosphatidylinositol-(4,5)-bisphosphate hydrolysis, G_i mediated inhibition of adenyl cyclase, and G_i mediated stimulation of the mitogenic Ras- MAP kinase. To further elucidate the biological activity of LPA and potentially identify new LPA binding receptors, …

Export Of Carbon, Nutrients And Microbiological Indicators In Beaver Creek Watershed, Tennessee, Si Chen

Masters Theses

Storms are the most important events impacting stream water quality at the watershed-scale. With the goal to develop effective water resource management strategies for the impaired Beaver Creek Watershed in East Tennessee, the impacts of storm events on water quality were assessed by monitoring the intra-storm dynamics of the export of carbon, nutrients, and microbiological indicators (E. coli), which are parameters critical to water quality and ecological functions of the target watershed. The dynamics of carbon export from the Beaver Creek Watershed as represented by dissolved organic carbon revealed distinct carbon transport mechanisms as a function of storm …

Subject matter experts can use the process to evaluate the condition of a test asset by inputting data into the developed software system. The process was designed around the concept of evaluating the condition of a system against ten parameters that encompass all of the aspects of a system that would be considered in determining its overall condition. A scale of zero (failed) to ten …

In Vitro Analysis Of The Anti-Influenza Virus Activity Of Pomegranate Products And Fulvic Acid, Radha Ganapathy

Masters Theses

In traditional cuban medicine, pomegranate fruits have been used to treat acidosis, dysentery, microbial infections, diarrhoea, helminthiasis; haemorrhage and respiratory pathologies [Vuorela et al., 2003; Roig, 1974; Jimenez et al., 1979; Seoane, 1984].Pomegranates contain high levels of Polyphenolic compounds, which are largely responsible for the fruit’s antioxidant properties. A number of studies have demonstrated that polyphenolic complexes derived from other plants have antiviral effects, suggesting that antiviral activity may also reside in the polyphenol (PP) fraction of pomegranates.

The decay of organic matter generates an extremely heterogeneous mixture of organic molecules referred to as humic substances. They are sub-classified on …

Identification And Quantification Of Cotton Yield Monitor Errors, Jason Clay Head

Cotton yield monitors are an important part of a precision agriculture program and are becoming widely used by cotton producers for making management decisions. Members of the cotton industry have shown interest in using cotton yield monitors for collecting data from production scale variety yield trials (experiments that test yield performance for numerous varieties). Weighing boll buggies are the current industry standard for measuring yield in variety trials. This process is time consuming and requires extra equipment and labor. The ability to use a yield monitor for measuring yield would streamline variety trial harvesting. Recommendations for the Ag Leader cotton …

The Impact Of Iron Deprivation On The Metabolism Of Escherichia Coli As Measured By Targeted Hplc-Ms/Ms Based Metabolomics, Jamie Rhea Light

Masters Theses

Iron is a necessity for all living organisms, and bacteria typically need an internal concentration of iron in the micromolar range.¹ This becomes quite problematic, especially in pathogenic bacteria, because the concentration of free ions within the human body is only 10^-24 Molar due to iron binding proteins, like transferrin.¹ In order to circumvent this problem, bacteria produce small iron chelating molecules called siderophores.¹ The bacteria utilized for this study, a K-12 derivative of Escherichia coli, produce only one siderophore, enterobactin. Not only is the transcription of genes associated with iron acquisition initiated in response …

Anti-Judaic Religious Polemic And Apocalyptic Thought In The Disputation Of Majorca And Its Later Manuscript Tradition, Geoffrey Kyle Martin

Masters Theses

In this study, I first examine the Disputation of Majorca (1286) and analyze how its Christian disputant, Inghetto Contardo, blended apocalyptic thought and anti-Judaic discourse. Although other studies, most notably Ora Limor’s critical edition, have touched upon the nature of Inghetto’s arguments, none have discussed his clear implementation of intertwined anti-Judaic religious polemic and apocalyptic thought in a satisfactory manner. I place Inghetto in an apocalyptic milieu of the later thirteenth century that especially emphasizes the imminence of the Last Days. In effect, Inghetto’s employment of St. Jerome’s Daniel exegesis is perfectly suited to 1286, when Jews are most likely …

A Study To Evaluate The Suitability Of A Centrifuge As A Dynamic Flight Simulator For F/A-18 Strike Fighter Mission Training, Richard Michael Masica

Masters Theses

The purpose of this study was to evaluate the suitability of using an existing 25-ft radius centrifuge as a dynamic flight simulator for “full mission” F/A-18 strike fighter mission training with respect to the representativeness of pilot-perceived motion and acceleration cues.

The methodology employed in this study consisted of analyzing F/A-18 mission tasks, collecting pilot opinion surveys of important sensory cues needed in simulator training, and conducting an analysis of human pilot perceptual problems caused by centrifuge motion constraints.

This study identified a number of issues indicating that a centrifuge-based flight simulator shows limited potential for use in “full mission” …

Baseline Survey And Habitat Analysis Of Aquatic Salamanders In The Pigeon River, North Carolina, Nikki J. Maxwell

Masters Theses

The Pigeon River was severely impacted beginning in the early 1900s by a paper mill located in Canton, North Carolina. The mill discharged chemical byproducts into the Pigeon River until 1992 when the paper mill modified their processes. As a result, water quality improved but the status of salamander species in the Pigeon River was unknown. Worldwide amphibian declines over the last 20 years have drawn attention to the need for more research and a better understanding of species-specific habitat relationships. There is concern about amphibian population declines because amphibians are critical to the balance of ecosystems and are considered …

Masters Theses

The use of computers for automated music analysis could benefit several aspects of academia and industry, from psychological and music research, to intelligent music selection and music copyright investigation. In the following thesis, one of the first steps of automated musical analysis, i.e., monophonic instrument recognition, was explored. A multi-threaded artificial neural network was implemented and used as the classifier in order to utilize multi-core technology and allow for faster training. The parallelized batch-mode backpropagation algorithm used provided linear speedup, an improvement to the current literature. For the classification experiments, eleven different sets of instruments were used, starting with perceptively …

Applications Of Bret: The Detection And Visualization Of Protein Interactions And Intramolecular Conformational Changes, Lindsay Anne Staron

Masters Theses

Bioluminescence is a phenomenon in which chemical energy is converted into light energy. Here, the oxidation of a luciferin substrate, catalyzed by a luciferase enzyme, results in the emission of a photon. This biological process is exploited in a technology referred to as Bioluminescence Resonance Energy Transfer (BRET). As its name implies, BRET depends on a nonradiative energy transfer event that occurs between a donor luciferase and an acceptor fluorophore. Fusion of the donor and acceptor molecules to a protein(s) of-interest allows one to identify and monitor molecular events, such as protein interactions or hormone binding events, based solely on …

Casein Micelles From Bovine Milk: Ethanol Induced Changes In Hydrophobicity And Interaction With Native Whey Proteins, Raymundo Trejo

Masters Theses

Caseins, in the form of micelles, are the most abundant milk protein. The nature of these micelles is still not fully understood and several models have been proposed. The first chapter discusses this topic, along with the importance of milk proteins to the food industry, and their allergenic properties.

In the second chapter the changes in the hydrophobicity of dissociated casein micelles are explored. As new applications for milk proteins are discovered, it becomes more important to understand their physicochemical properties when subjected to different treatments. It has been reported that casein micelles disassociate when heated in the presence of …

Cooperation In The Commonwealth: Perceptions Of Partnership Initiatives Between Virginia's Academic Health Sciences Libraries And Select (Contiguous) Public Library Systems For The Provision Of Consumer Health Information Services, Jessica Lynn Waugh

Masters Theses

Increasing numbers of Americans are seeking information about health and medicine. The advent of the Internet has ushered in an explosion of resources, but no mediating device to help lay people discern between authoritative current data, opinion pieces or unsubstantiated anecdotes. The field of consumer health is ripe with programs and initiatives designed to address the issue of access and education, but those are often scattered, spottily coordinated, poorly advertised and, in some cases, needlessly duplicated. The formation of robust partnerships between two major entities attempting to provide consumer health information (public libraries and academic health sciences libraries) seems logical …

Ammianus And Constantius: The Portrayal Of A Tyrant In The Res Gestae, Sean Robert Williams

Masters Theses

The purpose of this thesis is to demonstrate that the late Roman historian Ammianus Marcellinus used his portrayal of the emperor Constantius II (r. 337-361) as a response to Christian polemic against the pagan emperor Julian (r. 361-363). It argues that, based on the similarities between Ammianus’ account of Constantius and some Christian polemical accounts of Julian, the Res Gestae should be seen as part of the broader discourse between Christians and pagans that began after the death of Valens at Adrianople in 378. By examining the narrative similarities Ammianus shares with several of his prominent Christian contemporaries—notably Gregory of …

Identification And Characterization Of Novel Cellulases From Dissosteira Carolina (Orthoptera: Acrididae) And Molecular Cloning And Expression Of An Endo-Beta-1,4-Glucanase From Tribolium Castaneum (Coleoptera: Tenebrionidae), Jonathan Duran Willis

Masters Theses

Cellulosic ethanol holds great potential as biofuel due to its sustainability and renewability, yet recalcitrance of cellulosic feedstocks prevents cost-efficient ethanol production. Enzymatic catalysis of lignocellulosic biomass has the greatest biotechnological potential for cost reductions to the production process. Even though numerous cellulolytic enzymes have been identified in bacteria, plant, and fungi, insects remain as a fairly unexplored prospecting resource. Many insects, either via endogenously or symbiotically derived enzymes, use cellulose as substrate for their energetic needs. Novel cellulases from insects may have the potential to be more efficient than alternative enzymes in the conversion of cellulose to fermentable sugars …

Architectural Sampling: The Integration And Manipulation Of Meaning, Jacob Stafford Thomas

Masters Theses

This thesis is an investigation into the appropriation and assimilation of meaning by examining the relationship between the technique and meaning of the musical sample and meaning and memory in architecture. As a previously recorded sound integrated into a new work, the sample has a dual identity as both detail and artifact. It is a detail of two or more wholes: an original condition and the new condition, and an artifact from the context of the work from which it was taken. In architectural design, each recognizable form and spatial arrangement is a sample from a prototype with its own …

Integrating A Variety Of Cultures And Diversity Into The Upper Elementary Curriculum, Tammy Joy Hamlin

Masters Theses

Research has overwhelmingly shown that something needs to be done to combat the increasing problem of high minority drop-out rates. Many people still do not acknowledge that schools need to do anything differently. Instead the problem is blamed on the home life and economics. Some teachers feel that low-income inner city, minority students, simply are not capable of being successful academically. Society often does not realize how poor the minority drop out rates are in their school districts. Some administrations have chosen to hide the statistics. For instance one New York school district in this research promoted that almost all …

This study examined the influence of government, politicians and advertisers on the content of Croatian Public Television (HTV) news. This research examined whether HTV has remained state TV and under as strong government influence as it was in the former Yugoslavia? Or has it transformed into public TV, which has been the goal since Croatia gained independence in 1991? Or has it become commercial TV?

The data were gathered through 10 semi-structured in-depth interviews with journalists and producers in the HTV news department and through a content analysis of HTV’s main newscast, Dnevnik.

The major findings suggest there is still …

Effects On Digital Image Quality When Photographing Through A Transparent Material Used To Hold Or Flatten An Original Object, Paul E. Howell

Masters Theses

An increasing number of libraries and archives are initiating projects where new and updated technologies make it practical to digitize materials containing color and fine detail. Many of the imaging systems and methods used for this process require that some type of glass or plastic be placed over the original to hold it flat and in the correct position during image capture. The physical properties of a material placed between an original object and the capture system or camera, during digitization, could possibly affect the accuracy of image color and quality being reproduced by the system. This investigation provides an …

Design And Implementation Of A High Temperature Fully-Integrated Bcd-On-Soi Under Voltage Lock Out Circuit, Nora Dianne Bull

Masters Theses

As concern about the environment has grown in recent years, alternatives in the automotive industry have become an important topic for researchers. One alternative being considered is electric vehicles, which utilize electric motors. DC/AC inverters and DC/DC power converters control these electric motors. A logic circuit is needed to power these converters; however, the logic generators inherently operate at a voltage too low to power the motors. A device known as the gate driver is the interface between the logic generators (or microcontroller) and the power devices (power converter). The gate driver provides the power needed to drive the power …
