Effect Of Toothbrush Abrasion On Frictional Resistance Of Aesthetic Orthodontic Archwires, Stephen Alexander Yamodis

UNLV Theses, Dissertations, Professional Papers, and Capstones

Fixed orthodontic appliances (braces) are one of the most widely used appliances to correct malocclusion, however many patients prefer less metal display. To meet this demand more esthetically pleasing brackets and archwires have been developed. These esthetic components are often clear, white or tooth colored. Coatings of various types are commonly used to produce an esthetic archwire. However, these coating materials tend to wear and degrade, which may cause binding and increased resistance to friction, thereby potentially reducing the efficiency of tooth movement. Therefore, in vitro testing of tooth brush abrasion on frictional resistance of various aesthetic archwires was tested. …

United States Food Law Update: Moving Toward A More Balanced Food Regulatory Regime, A. Bryan Endres, Nicholas R. Johnson

Journal of Food Law & Policy

For decades, the federal government has played a significant role in promoting healthy eating. In the early 1900s, the United States Department of Agriculture (USDA) promoted a foundational diet of milk, proteins, fruits and vegetables, and grains. Most Americans are at least somewhat familiar, although perhaps confused, with the more nuanced healthy eating recommendations contained in the food pyramid - first employed in 1992. And virtually every American has experienced the federally supported school lunch program. In the first half of 2011, these two iconic programs underwent significant change as part of a stepped-up effort to improve the health of …

Surfactant Induced Reservoir Wettability Alteration: Recent Theoretical And Experimental Advances In Enhanced Oil Recovery, Yefei Wang, Huaimin Xu, Weizhao Yu, Baojun Bai, Xinwang Song, Jichao Zhang

Geosciences and Geological and Petroleum Engineering Faculty Research & Creative Works

Reservoir wettability plays an important role in various oil recovery processes. The origin and evolution of reservoir wettability were critically reviewed to better understand the complexity of wettability due to interactions in crude oil-brine-rock system, with introduction of different wetting states and their influence on fluid distribution in pore spaces. The effect of wettability on oil recovery of waterflooding was then summarized from past and recent research to emphasize the importance of wettability in oil displacement by brine. The mechanism of wettability alteration by different surfactants in both carbonate and sandstone reservoirs was analyzed, concerning their distinct surface chemistry, and …

Assessment Of Corrosion Potential Of Coarse Backfill Aggregates For Mechanically Stabilized Earth Walls, Anita Thapalia, David M. Borrok, Soheil Nazarian, Jose Garibay

Geosciences and Geological and Petroleum Engineering Faculty Research & Creative Works

The service life of mechanically stabilized earth walls depends on the rate of corrosion of the metallic reinforcements used in their construction. The assessment of corrosion potential requires an accurate evaluation of pH, resistivity, and sulfate and chloride concentrations of aqueous solutions in contact with the surrounding aggregate. Highway agencies tend to use larger aggregates that contain only a small amount of fine material (passing the Number 40 sieve) in the backfill. Evaluation of the electrochemical parameters of coarse aggregates is challenging because traditional evaluation methods call for the use of fine material. In this study, the suitability of traditional …

Ground Layer Response To Disturbance In The Pine-Dominated Eastern Foothill Region Of West-Central Alberta, Canada, Rebecca Elizabeth Mooneyhan Mcclelland

Dissertations

The canopy cover of the Pinus contorta forests of west-central Alberta, dictates colonization of the forest floor ground layer. This dynamic ground layer is a mosaic of feather mosses and reindeer lichens in a system driven by disturbance. In this project, anthropogenic was used to control canopy cover change and study its effects on the ground layer. Timber companies selectively mechanically thinned sections producing three experimental areas with uncut controls. Data were collected from 182, 6.5 m2 plots located in the four thinning areas. Six general areas of inquiry were posed around determining ground layer responses to canopy opening: 1) …

Endurance Markers Are Related With Local Neuromuscular Response For The Intact But Not For The Acl Reconstructed Leg During High Intensity Running, Kostas Patras, Giorgos Ziogas, Stavros Ristanis, Elias Tsepis, Vasilis Tsiaras, Nikolaos Stergiou, Anastasios D. Georgoulis

Journal Articles

AIM: It has been demonstrated that the local neuromuscular response during high intensity exercise has a strong relationship with endurance markers. However, a diminished neuromuscular response has been reported for the operated leg in athletes having undergone anterior cruciate ligament reconstruction (ACLR). The purpose of the present study was to examine the relationships between endurance markers and the EMG response during high intensity running in ACLR athletes. METHODS: Fourteen ACLR soccer players underwent a GXT test to volitional exhaustion and a 10-min bout of high intensity running. During the 10-min bout, EMG data were recorded at the 3rd …

Identification Of Factors Involved In Dna Methylation Of Cpg-Island-Promoters, Yan Zhang

Dissertations and Theses (Open Access)

Repression of many tumor suppressor genes (TSGs) in cancer is mediated by aberrantly increased DNA methylation levels at promoter CpG islands (CGI). About one-fourth of empirically defined human promoters are surrounded by or contain clustered repetitive elements. It was previously observed that a sharp transition of methylation occurs between highly methylated repetitive elements (SINE or LINE) and unmethylated CGI-promoters (e.g. P16, VHL, CDH and RIL) in normal tissues. The functions that lead to increased CGI methylation in cancer remain poorly understood. We propose that CGI-promoters contain cis-elements for triggering de novo DNA methylation. In the first part of our project, …

Dual Targeting Of Tumor Angiogenesis And Chemotherapy By Endostatin- Cytosine Deaminase-Uracil Phosphoribosyltransferase, Chun-Te Chen

Dissertations and Theses (Open Access)

Antiangiogenesis is a promising anti-tumor strategy through inhibition tumor vascularformation to suppress tumor growth. Targeting specific VEGF/R has been showntherapeutic benefits in many cancer types and become a first approvedantiangiogenic modalities by Food and Drug Administration (FDA) in United States.However, interruption of homeostasis in normal tissues that is likely due to theinhibition of VEGF/R signaling pathway induces unfavorable side effects. Moreover,cytostatic nature of antiangiogenic drugs frequently causes less tumor cell specifickilling activity, and cancer cells escaped from cell death induced by these drugseven gain more malignant phenotypes, resulting in tumor invasion and metastasis.To overcome these issues, we developed a novel …

Understanding Nanog’s Role in Cancer Biology

Mark Daniel Badeaux

Supervisory Professor Dean Tang, PhD

The cancer stem cell model holds that tumor heterogeneity and population-level immortality are driven by a subset of cells within the tumor, termed cancer stem cells. Like embryonic or somatic stem cells, cancer stem cells are believed to possess self-renewal capacity and the ability to give rise to a multitude of varieties of daughter cell. Because of cancer’s implied connections to authentic stem cells, we screened a variety of prostate cancer cell lines and primary tumors in order to determine if any notable ‘stemness’ genes were …

Definition Of The Landscape Of Chromatin Structure At The Frataxin Gene In Friedreich’S Ataxia, Eunah Kim

Dissertations and Theses (Open Access)

Friedreich’s ataxia (FRDA) is caused by the transcriptional silencing of the frataxin (FXN) gene. FRDA patients have expansion of GAA repeats in intron 1 of the FXN gene in both alleles. A number of studies demonstrated that specific histone deacetylase inhibitors (HDACi) affect either histone modifications at the FXN gene or FXN expression in FRDA cells, indicating that the hyperexpanded GAA repeat may facilitate heterochromatin formation. However, the correlation between chromatin structure and transcription at the FXN gene is currently limited due to a lack of more detailed analysis. Therefore, I analyzed the effects of the hyperexpanded GAA …

The Cytoplasmic Tail Of Mhc Class I Molecules Plays A Critical Role In Dendritic Cell-Induced T Cell Immunity, Tania G. Rodriguez-Cruz

Dissertations and Theses (Open Access)

The presentation of MHC class I (MHC-I)/peptide complexes by dendritic cells (DCs) is critical for the maintenance of central tolerance to self and for the regulation of cytotoxic T lymphocytes (CTL)-mediated adaptive immune responses against pathogens and cancer cells. Interestingly, several findings have suggested that the cytoplasmic tail of MHC class I plays a functional role in the regulation of CTL immune responses. For example, our previous studies demonstrated that exon 7-deleted MHC-I molecules not only showed extended DC cell surface half-lives but also induced significantly increased CTL responses to viral challange invivo. Although exon 7-deleted variant of MHC-I does …

Field-Controlled Electron Transfer And Reaction Kinetics Of The Biological Catalytic System Of Microperoxidase-11 And Hydrogen Peroxide, Yongki Chou, Siu-Tung Yau

Electrical and Computer Engineering Faculty Publications

Controlled reaction kinetics of the bio-catalytic system of microperoxidase-11 and hydrogen peroxide has been achieved using an electrostatic technique. The technique allowed independent control of 1) the thermodynamics of the system using electrochemical setup and 2) the quantum mechanical tunneling at the interface between microperoxidase-11 and the working electrode by applying a gating voltage to the electrode. The cathodic currents of electrodes immobilized with microperoxidase-11 showed a dependence on the gating voltage in the presence of hydrogen peroxide, indicating a controllable reduction reaction. The measured kinetic parameters of the bio-catalytic reduction showed nonlinear dependences on the gating voltage as the …

A Comparison Of Renewable Portfolio Standards And Feed-In Tariffs As Legislative Mechanisms To Provide Renewable Power Incentives: Impacts On Power Supply, Transmission, And Grid Intermittency, Steven Ferrey

Suffolk University Law School Faculty Works

A federalist form of government is used in several important nations, including the United States, Germany, India, Australia, Brazil, Canada, Malaysia, and Switzerland. A federalist form of government divides political sovereignty between a central federal authority and constituent states or provinces. To implement new government policy regulating private power, the challenging transcendent issues are legal and regulatory, rather than technical. Certain measures in various industrialized countries, when implemented at the state rather than federal level, must be designed and implemented carefully to achieve a legal, regulatory fit in a federalist system of government.

For purposes of comparison, this article considers …

Application Oriented Analysis Of Large Scale Datasets, Prashant Shivaji Paymal

Student Work

Diverse application areas, such as social network, epidemiology, and software engineering consist of systems of objects and their relationships. Such systems are generally modeled as graphs. Graphs consist of vertices that represent the objects, and edges that represent the relationships between them. These systems are data intensive and it is important to correctly analyze the data to obtain meaningful information. Combinatorial metrics can provide useful insights for analyzing these systems. In this thesis, we use the graph based metrics such as betweenness centrality, clustering coefficient, articulation points, etc. for analyzing instances of large change in evolving networks (Software Engineering), and …

Putting Students At The Center Of Legal Education: How An Emphasis On Outcome Measures In The Aba Standards For Approval Of Law Schools Might Transform The Educational Experience Of Law Students, Janet W. Fisher

Southern Illinois University Law Journal

Legal education has been notably absent from the assessment movement that has been underway in American higher education for over twenty-five years.  Accreditors of virtually every other area of professional education in the United States have adopted assessment of educational outcomes as part of their accreditation process.  Legal education is poised to join this movement as the American Bar Association considers revisions to its Standards for Approval of Law Schools that would emphasize educational outcomes.
This Article explores how the assessment of educational outcomes might be implemented in legal education at the institutional, programmatic and course levels.  The Article focuses …

Fill Material Pollution Under The Clean Water Act: A Need For Legislative Change, Kory R. Watson

Southern Illinois University Law Journal

The Clean Water Act was implemented to restore and maintain the Nation’s waters. The National Pollutant Discharge Elimination System is the principal permitting scheme under the Clean Water Act that is designated to achieve that objective.  In the wake of ambiguous regulations on fill material, a loophole in the Clean Water Act has arisen. Currently, an entity can apply for a fill permit to discharge waste normally regulated under the Nation Pollutant Discharge Elimination System if the discharge is composed of a sufficiently high concentration of solids. This Comment discusses the regulations on fill permitting and the cases interpreting them. …

Precisely Serializable Snapshot Isolation, Stephen Anthony Revilak

Graduate Doctoral Dissertations

Snapshot Isolation (SI) is a method of database concurrency control that uses timestamps and multiversioning, in preference to pessimistic locking. Since its introduction in 1995, SI has become a popular isolation level, and has been implemented in a variety of database systems: Oracle, Postgres, Microsoft SQL Server, and others. Despite the benefits that SI offers, one of the things it cannot provide is serializability. Past approaches for serializable SI have focused on avoiding dangerous structures (or essential dangerous structures). Dangerous structures are patterns of transaction dependencies that indicate the potential for a non-serializable execution; however, the presence of dangerous structures …

Analysis Of Leo Radiation Environment And Its Effects On Spacecraft's Critical Electronic Devices, Luz Maria Martines Sierra

Doctoral Dissertations and Master's Theses

Spacecraft, space stations, satellites and astronauts are exposed to an increased level of radiation when in space, and it is important to evaluate the risks associated with extended radiation exposures in missions and space travel in general. The thesis focuses on the LEO radiation environment and how the particles in it interact with materials. Using existing empirical models, the exposed dosage due to the LEO space environment radiation sources, as a function of orbital altitude, orbital inclination and duration is studied. The physical processes that can result in failures and long term degradations of electronic devices due to solar radiation, …

Social Learning And General Strain Theories' Relationship With Prescription Stimulant Misuse For Academic Purposes Among College Students, Julianne Ong

HIM 1990-2015

The instrumental misuse of prescription stimulants as "study drugs", particularly by college students, is a serious issue that needs to be further investigated. Using data from a sample of 549 University of Central Florida Orlando students, the current study tested the relationship between prescription stimulant misuse and social learning theory, as well as general strain theory. Approximately 17% of participants reported misusing prescription stimulants for academic purposes at least once in the past year. Findings show support for social learning theory; the number of friends who use prescription stimulants and the individual's attitudes about the effectiveness of the drugs are …

Dna Electrophoretic Migration Patterns Change After Exposure Of Jurkat Cells To A Single Intense Nanosecond Electric Pulse, Stefania Romeo, Luigi Zeni, Maurizio Sarti, Anna Sannino, Maria Rosaria Scarfi, P. Thomas Vernier, Olga Zeni

Bioelectrics Publications

Intense nanosecond pulsed electric fields (nsPEFs) interact with cellular membranes and intracellular structures. Investigating how cells respond to nanosecond pulses is essential for a) development of biomedical applications of nsPEFs, including cancer therapy, and b) better understanding of the mechanisms underlying such bioelectrical effects. In this work, we explored relatively mild exposure conditions to provide insight into weak, reversible effects, laying a foundation for a better understanding of the interaction mechanisms and kinetics underlying nsPEF bio-effects. In particular, we report changes in the nucleus of Jurkat cells (human lymphoblastoid T cells) exposed to single pulses of 60 ns duration and …
