Amaethon – A Web Application For Farm Management And An Assessment Of Its Utility, Tyler Yero Dec 2012

Amaethon – A Web Application For Farm Management And An Assessment Of Its Utility, Tyler Yero

Master's Theses

Amaethon is a web application that is designed for enterprise farm management. It takes a job typically performed with spreadsheets, paper, or custom software and puts it on the web. Farm administration personnel may use it to schedule farm operations and manage their resources and equipment. A survey was con- ducted to assess Amaethon’s user interface design. Participants in the survey were two groups of students and a small group of agriculture professionals. Among other results, the survey indicated that a calendar interface inside Amaethon was preferred, and statistically no less effective, than a map interface. This is despite the …

The Impact Of Outward Remodeling On Vasodilation In Skeletal Muscle Resistance Arteries, Ryan Robert Gallagher Dec 2012

The Impact Of Outward Remodeling On Vasodilation In Skeletal Muscle Resistance Arteries, Ryan Robert Gallagher

Master's Theses

Peripheral arterial occlusive disease (PAOD) is an ischemic disease characterized by narrowing of the peripheral arteries due to the accumulation of atherosclerotic plaque in the inner lining of the vessels, which disrupts blood flow to downstream tissues. Blood can be redirected into collateral vessels, natural bypasses around arterial occlusions, causing shear-induced outward remodeling of the vessels. The enlarged vessels facilitate transfer of increased blood flow to downstream tissues. The remodeling process, however, may impair vasodilation, which in turn may cause or contribute to intermittent claudication- transient pain brought on by locomotion. To stimulate the growth of collateral arteries, the femoral …

Design And Simulation Of Passive Thermal Management System For Lithium-Ion Battery Packs On An Unmanned Ground Vehicle, Kevin Kenneth Parsons Dec 2012

Design And Simulation Of Passive Thermal Management System For Lithium-Ion Battery Packs On An Unmanned Ground Vehicle, Kevin Kenneth Parsons

Master's Theses

The transient thermal response of a 15-cell, 48 volt, lithium-ion battery pack for an unmanned ground vehicle was simulated with ANSYS Fluent. Heat generation rates and specific heat capacity of a single cell were experimentally measured and used as input to the thermal model. A heat generation load was applied to each battery and natural convection film boundary conditions were applied to the exterior of the enclosure. The buoyancy-driven natural convection inside the enclosure was modeled along with the radiation heat transfer between internal components. The maximum temperature of the batteries reached 65.6 °C after 630 seconds of usage …

N-Glycosylation Dictates Proper Processing Of Organic Anion Transporting Polypeptide 1b1, Juan Yao, Weifang Hong, Jiujiu Huang, Kai Zhan, Hong Huang, Mei Hong Dec 2012

N-Glycosylation Dictates Proper Processing Of Organic Anion Transporting Polypeptide 1b1, Juan Yao, Weifang Hong, Jiujiu Huang, Kai Zhan, Hong Huang, Mei Hong

School of Information Faculty Publications

Organic anion transporting polypeptides (OATPs) have been extensively recognized as key determinants of absorption, distribution, metabolism and excretion (ADME) of various drugs, xenobiotics and toxins. Putative N-glycosylation sites located in the extracellular loops 2 and 5 is considered a common feature of all OATPs and some members have been demonstrated to be glycosylated proteins. However, experimental evidence is still lacking on how such a post-translational modification affect the transport activity of OATPs and which of the putative glycosylation sites are utilized in these transporter proteins. In the present study, we substituted asparagine residues that are possibly involved in N-glycosylation with …

Contemporary Us-American Satire And Consumerism (Crews, Coupland, Palahniuk), J.C. Lee Dec 2012

Contemporary Us-American Satire And Consumerism (Crews, Coupland, Palahniuk), J.C. Lee

CLCWeb: Comparative Literature and Culture

In her article "Contemporary US-American Satire and Consumerism (Crews, Coupland, Palahniuk)" J.C. Lee focuses on contemporary satire's potential (or lack thereof) for change, reform, or rebellion through an investigation of works by Harry Crews, Douglas Coupland, and Chuck Palahniuk, all of which target consumerism. The said writers employ satire not to initiate rebellion or cultural change, but to reflect the problematic role of institutions in modern life and, in turn, the potential, even hope, for personal growth. Lee's analysis of texts by Crews, Coupland, and Palahniuk is intended to question satire's potential as a form of cultural critique and institutional …

Population Dynamics In Predynastic Upper Egypt: Paleodemography Of Cemetery Hk43 At Hierakonpolis, Ernest King Batey Iii Dec 2012

Population Dynamics In Predynastic Upper Egypt: Paleodemography Of Cemetery Hk43 At Hierakonpolis, Ernest King Batey Iii

Graduate Theses and Dissertations

The site of Hierakonpolis is considered to have played an important role in the development of the Egyptian state, which formed at end of the fourth millennium BC. Archaeological evidence suggests that, for the Middle and Late Predynastic periods (ca. 3900-3200 BC), Hierakonpolis may be characterized as having experienced the following: a growth in both settlement and population size, an increased reliance on cereal agriculture, development of craft specialization, and the presence of a Social hierarchy as interpreted from an observed increase in the differentiation of mortuary behavior. Historical data suggest that these Social and economic changes would have affected …

On The Maintenance Modeling And Optimization Of Repairable Systems: Two Different Scenarios, Suzan Alaswad Dec 2012

On The Maintenance Modeling And Optimization Of Repairable Systems: Two Different Scenarios, Suzan Alaswad

Graduate Theses and Dissertations

The use of mathematical modeling for the purpose of analyzing and optimizing the performance of repairable systems is widely studied in the literature. In this dissertation, we study two different scenarios on the maintenance modeling and optimization of repairable systems. First, we study the long-run availability of a traditional repairable system that is subjected to imperfect corrective maintenance. We use Kijima's second virtual age model to describe the imperfect repair process. Because of the complexity of the underlying probability models, we use simulation modeling to estimate availability performance and meta-modeling to convert the reliability and maintainability parameters of the repairable …

An Economic Alternative To The C Chart, Ryan William Black Dec 2012

An Economic Alternative To The C Chart, Ryan William Black

Graduate Theses and Dissertations

Because the probability of Type I error is not evenly distributed beyond upper and lower three-sigma limits the c chart is theoretically inappropriate for a monitor of Poisson distributed phenomena. Furthermore, the normal approximation to the Poisson is of little use when c is small. These practical and theoretical concerns should motivate the computation of true error rates associated with individuals control assuming the Poisson distribution. An economic alternative to the c chart is described as a statistical model of upward shift from c0 to c1 and the two charts are compared in theory. For a range of c chart …

Characterization And Epidemiology Of Soybean Vein Necrosis Associated Virus, Jing Zhou Dec 2012

Characterization And Epidemiology Of Soybean Vein Necrosis Associated Virus, Jing Zhou

Graduate Theses and Dissertations

Soybean vein necrosis disease (SVND) is widespread in major soybean-producing areas in the U.S. The typical disease symptoms exhibit as vein clearing along the main vein, which turn into chlorosis or necrosis as season progresses. Double-stranded RNA isolation and shot gun cloning of symptomatic tissues revealed the presence of a new tospovirus, provisionally named as Soybean vein necrosis associated virus (SVNaV). The presence of the virus has been confirmed in 12 states: Arkansas, Illinois, Missouri, Kansas, Tennessee, Kentucky, Mississippi, Maryland, Delaware, Virginia and New York. Symptomatic samples collected from eight states (AR, IL, MO, MS, KS, TN, MD and DE), …

Family Cancer History And Pedigrees As A Public Health Intervention For Promoting Health And Preventing Prostate Cancer In African American Men, Holisa Wharton Dec 2012

Family Cancer History And Pedigrees As A Public Health Intervention For Promoting Health And Preventing Prostate Cancer In African American Men, Holisa Wharton

All Dissertations

ABSTRACT
Prostate cancer is the most common cancer diagnosed in men and the second leading cause of cancer death among men in the United States. African-American men have substantially higher prostate cancer incidence and mortality than European-American men. It is unclear whether this incidence is due to acquired DNA changes (sporadic cancer) or if germline Mendelian genetics/genomics (inherited cancer) is the source of this health disparity. To explore this cause, the focus of this dissertation paper is family health history and hereditary prostate cancer. A family history tool is the most commonly used predictive instrument for hereditary prostate cancer. The …

Induced Elastic Matrix Synthesis Within 3-Dimensional Collagen Constructs, Lavanya Venkataraman Dec 2012

Induced Elastic Matrix Synthesis Within 3-Dimensional Collagen Constructs, Lavanya Venkataraman

All Dissertations

Elastin, a primary component of elastic arteries, maintains structural stability of the cyclically recoiling artery, and critically regulates vascular cell behavior. Accelerated degradation of elastic matrix, such as that seen in vascular pathologies like abdominal aortic aneurysms (AAA), can therefore severely compromise vessel homeostasis. Tissue engineering and in-situ matrix repair strategies evaluated so far are primarily limited in inducing adult vascular cells to replicate the complex elastic matrix assembly process, and restore lost matrix integrity. Previously, our lab established the elastogenic benefits of concurrent delivery of TGF-β1 and HA-oligomers (together termed elastogenic factors, EFs), within 2D cultures of rat aortic …

Essays On Sourcing Decisions: A Behavioral Perspective, David Hall Dec 2012

Essays On Sourcing Decisions: A Behavioral Perspective, David Hall

All Dissertations

This dissertation examines how managers make and perceive supply chain governance decisions. A plethora of supply chain management literature suggests that managers will a priori choose a governance form that will manage risks while pursuing benefits. A number of theories have been used to inform this view: agency, resource-based view and transaction cost economics. Agency theory, the resource-based view and transaction cost economics all share the common assumption that a manager is considering both the risks and benefits of their decisions. In addition each of these perspectives assumes managers are boundedly rational. Taken together these two assumptions suggest managers have …

Essays On Eminent Domain And Property Rights, Meng Wang Dec 2012

Essays On Eminent Domain And Property Rights, Meng Wang

All Dissertations

ABSTRACT
Shortly after the Supreme Court's decision in Kelo vs. City of New London, which expanded the scope of eminent domain power, thirty-seven states enacted legislation to restrict their local governments' use of eminent domain. This paper uses a model of the efficient limitation on government discretion to explain (1) the initial responses of local government to Kelo and (2) the subsequent responses of state legislatures. It shows that elimination of the public-use doctrine is plausibly welfare reducing since it introduces additional uncertainty without offsetting expanded benefits. I test two predictions of the theoretical analysis: First, the post-Kelo actions of …

Regulation Of The Lipid Raft Localization Of The Gal/Galnac Lectin, An Adhesin On The Surface Of The Human Protozoan Parasite, Entamoeba Histolytica, Amanda Goldston Dec 2012

Regulation Of The Lipid Raft Localization Of The Gal/Galnac Lectin, An Adhesin On The Surface Of The Human Protozoan Parasite, Entamoeba Histolytica, Amanda Goldston

All Dissertations

Lipid rafts, sterol- and sphingolipid-rich membrane microdomains, have been shown to control virulence in a variety of parasites including Entamoeba histolytica, an intestinal parasite that causes dysentery and liver abscess. Parasite cell surface receptors, such as the Gal/GalNAc lectin, facilitate attachment to host cells and extracellular matrix. The Gal/GalNAc lectin binds to galactose or N-acetylgalactosamine residues on host components, and is composed of heavy (Hgl), intermediate (Igl), and light (Lgl) subunits. Although Igl is constitutively localized to lipid rafts, Hgl and Lgl transiently associate with this compartment in a cholesterol-dependent fashion. Exposure to bonafide Gal/GalNAc lectin ligands is associated with …

Sensitivity Analysis In Magnetic Resonance Elastography And A Local Wavelength Reconstruction Based On Wave Direction, Christopher Gillam Dec 2012

Sensitivity Analysis In Magnetic Resonance Elastography And A Local Wavelength Reconstruction Based On Wave Direction, Christopher Gillam

All Dissertations

or the detection of early stage cancer. MRE utilizes interior data for its inverse problems, which greatly reduces the ill-posedness from which most traditional inverse problems suffer.
In this thesis, we first establish a sensitivity analysis for viscoelastic scalar medium with complex wave number and compare it with the purely elastic case. Also we estimate the smallest detectable inclusion for breast and liver, which is about twice larger than using the purely elastic model. We also found the existence of optimal frequency (50 Hz) that maximizes the detectability when the Voigt model is used.
Second, we propose a local wavelength …

Navigating The World Of Academia As A Mother And Contingent Faculty Member: A Narrative Inquiry, Kathryn Ledford

All Dissertations

Although women hold many professional positions, they are still held accountable to present gendered customs like parenting children. Additionally, women who work in higher education are surrounded by masculine norms. For academic women who are also mothers like the author, many obstacles confront their management of the interlocking spheres of home, work and self. An examination of these women's narratives will illuminate how women navigate the world of academia, while maintaining our roles as mothers and individual identities.
For women who are mothers of children under six years old, and who are also contingent faculty members at four-year institutions, both …

The Development Of Mennonite Music In The Congo: A Study In Musical Thought, Jill Michelle Schroeder-Dorn Dec 2012

The Development Of Mennonite Music In The Congo: A Study In Musical Thought, Jill Michelle Schroeder-Dorn

Dissertations

The purpose of this study was to examine musical thought among members of the Congolese Mennonite Church. Established and governed by missionaries, the music practices of the Church were initially modeled after Western services, which consisted of church choirs and four-part hymn singing. Congolese who chose to convert to Christianity had to adapt to a new musical system, which included not only properties of musical sound, but also concepts surrounding the music making experience, including what music is and what it has the power to accomplish. The church has now been in existence for over one hundred years, and musical …

A Unifying Approach To Behavioral Coverage, Elena Sherman Dec 2012

A Unifying Approach To Behavioral Coverage, Elena Sherman

School of Computing: Dissertations, Theses, and Student Research

Developing methods for validating that a program works as intended is one of the key research areas in software engineering. Ideally a program P must exhibit its expected be- havior, or property, φ on all of its inputs, i.e., P |= φ. The software engineering community has developed various program analysis approaches to assess whether P |= φ. In general, these approaches can be partitioned into dynamic and static program analysis. The former execute P on a particular input and checks that the execution conforms to φ. The latter in- terprets the code of P and check that on all …

The Fall Of "Augustinian Adam": Original Fragility And Supralapsarian Purpose, John Schneider Dec 2012

The Fall Of "Augustinian Adam": Original Fragility And Supralapsarian Purpose, John Schneider

University Faculty Publications and Creative Works

This essay is framed by conflict between Christianity and Darwinian science over the history of the world and the nature of original human personhood. Evolutionary science narrates a long prehuman geological and biological history filled with vast amounts, kinds, and distributions of apparently random brutal and pointless suffering. It has also unveiled an original human person with animal psychosomatic heredity. This narrative seems to discredit Christianity's (Augustinian) metanarrative of the Fall-Paradise Lost and Paradise Regained. The author contends that the Augustinian story and its character of Adam are implausible, anyway, for reasons of theology and apologetics. He proposes that Christians …

An Exploration Into The Perceived Effects Of International Volunteering And Service On Host Communities In The Global South, Katelyn Kerrigan Dec 2012

An Exploration Into The Perceived Effects Of International Volunteering And Service On Host Communities In The Global South, Katelyn Kerrigan

Master's Theses

Presently, we are witnessing an unprecedented expansion of Western youth participating in short-term (1 to 2 week) international volunteering and service (IVS) programs in developing countries located predominantly in the Global South (Lough, 2012; Sherraden et al., 2008). Current academic literature around the impacts IVS has on receiving host communities in developing countries is highly controversial. This study utilizes ethnographic research, involving a combination of participant -observation and semi-structured interviews, to gain the perspectives of the Fijian Highland villagers from the IVS host community, on the positive and negative effects of hosting American (aged 14-18) participating in short-term (one-week) international …
