Modulated Nanopores Using Pulse Anodization On Thin Aluminum, Mahesh Babu Gunukula May 2009

Modulated Nanopores Using Pulse Anodization On Thin Aluminum, Mahesh Babu Gunukula

UNLV Theses, Dissertations, Professional Papers, and Capstones

Nanoporous anodic aluminum oxide has traditionally been made in one of two ways: "Mild Anodization (MA)" or "Hard Anodization (HA)". The former method produces self-ordered pore structures but it is slow and only works for a narrow range of processing conditions; the latter method, which is widely used in the aluminum industry, is faster but it produces films with disordered pore structures. Here we report a novel approach termed "pulse anodization" that combines the advantages of the MA and HA processes. By designing the pulse sequences it is possible to control both the composition and pore structure of the anodic …


Gray Zones Of Modern Genocide, Megan Dale Lee May 2009

Gray Zones Of Modern Genocide, Megan Dale Lee

UNLV Theses, Dissertations, Professional Papers, and Capstones

Italian-Jewish chemist and Holocaust survivor Primo Levi wrote in his work The Drowned and the Saved about the "Gray Zone," or holding place for all things difficult to categorize about his experiences in the Nazi camp Auschwitz. Because human tendency is to divide things in a rigid dichotomy, he argued, anything without a set role is brushed aside. I have extended this Gray Zone to include mutually shared situations from modern genocide including: the relationship of race/land to genocide, the "Forced Victim-Perpetrator" (victim forced to commit atrocities against his or her own people), and the complex international reaction to genocidal …


Organization By Form: Applying Systems Theory To Urbanization, Michael Patrick Howe May 2009

Organization By Form: Applying Systems Theory To Urbanization, Michael Patrick Howe

UNLV Theses, Dissertations, Professional Papers, and Capstones

I have come to believe that the core of our declining physical, mental and community health dwells in the current practice of land use based development. Although today's land use codes began as a legitimate response to protect people's health and welfare it has since devolved into an unsustainable process. The failure of land-use zoning is rooted in an informational disconnect created by the segregation of land into distinct uses while offering generic design standards. Whereas the current mode of land use-based zoning results in an unpredictable physical form, Form-Based Codes foster a connection between the individual to the available …

Examining Play Among Young Children In Single-Age And Multi-Age Preschool Classroom Settings, Mia Song Youhne

UNLV Theses, Dissertations, Professional Papers, and Capstones

Advocates for multi-age classrooms claim multi-age groupings benefit children (Brynes, Shuster, & Jones, 1994). Currently, there is a lack of research examining play among students in multi-age classrooms. If indeed there is a positive benefit of play among children, research is needed to examine these behaviorsamong and between young children in single-age and multi-age classrooms. The purpose of this study was to determine if young children benefit from increased play opportunities.

This qualitative study utilized observations, interviews, and questionnaires to gather data from teachers, parents, and children regarding play interactions in both single-age and multi-age classrooms. The intent of this …

The Sheep Pass Formation, A Record Of Late Cretaceous And Paleogene Extension Within The Sevier Hinterland, East-Central Nevada, Peter Alexander Druschke

UNLV Theses, Dissertations, Professional Papers, and Capstones

The Sevier hinterland of western North America is considered by many to be an ancient proxy for the modern Andean Puna-Altiplano or Tibetan Plateau. However, controversies exist as tectonic setting and overall paleogeography of the Sevier hinterland during the Late Cretaceous and Paleogene. The Sheep Pass Formation type section within the southern Egan Range of east-central Nevada comprises a > 1 km thick sedimentary succession spanning the latest Cretaceous to Eocene, and provides a rare opportunity to test prevailing tectonic and paleogeographic models for the Sevier hinterland. New 1:12,000 scale field mapping inthe southern Egan Range indicates that up to three …

Text Categorization Based On Apriori Algorithm's Frequent Itemsets, Prathima Madadi

UNLV Theses, Dissertations, Professional Papers, and Capstones

Automatic Text categorization is the task of assigning an electronic document to one or more categories, based on its contents. There are many known techniques to efficiently solve categorization problems. Typically these techniques fall into two distinct methodologies which are either logic based or probabilistic. In recent years, many researchers have tried approaches which area hybrid of these two methodologies.

In this thesis, we deal with document categorization using Apriori Algorithm. The Apriori algorithm was initially developed for data mining and basket analysis applications in the relational databases. Although the technique is logic based, it also relies on the statistical …

Investigation Of Magnetic Resonance Imaging And Spectroscopy For The Detection Of Breast Cancer, Robert Thomas Etnire

UNLV Theses, Dissertations, Professional Papers, and Capstones

Magnetic resonance imaging (MRI) of the breast offers an alternative to screening mammography which may benefit those women at high risk for breast cancer, women under the age of 40, and those with dense breast tissue. One concern with MRI is the number of high false positives. Coupling MRI with magnetic resonance spectroscopy(MRS) may lower the number of false positives, and thus improve the diagnostic capabilities of MRI for the clinician. MRS for breast imaging focuses on the total choline containing compounds in the spectra in the suspected breast lesion to analyze areas of concern. The results of the study …


Ralph Vaughan William's The Pilgrim's Progress: Problems And Solutions For Future Performances, Richard Brandon Brunson May 2009

Ralph Vaughan William's The Pilgrim's Progress: Problems And Solutions For Future Performances, Richard Brandon Brunson

UNLV Theses, Dissertations, Professional Papers, and Capstones

The 1951 premier of The Pilgrim's Progress by Ralph Vaughan Williams was not a success. Two years later, Vaughan Williams told Michael Kennedy that "the Pilgrim is dead."1 A handful of attempts have been made to revive the work in the last few years, and a second recording of the opera by Richard Hickox has revived some interest.

Despite this progress, three big problematic areas (outlined by contemporary critics and Vaughan Williams) continue to stand in the way of staging this work. These three areas are the Apollyon scene, the homogeneity of the tempi, and the lack of dramatic elements …

Nathaniel Hawthorne And His Biblical Contexts, Conor Michael Walsh May 2009

Nathaniel Hawthorne And His Biblical Contexts, Conor Michael Walsh

UNLV Theses, Dissertations, Professional Papers, and Capstones

The majority of criticism and scholarship devoted to the fiction of Nathaniel Hawthorne takes for granted the relationship between Hawthorne and the Bible, focusing instead upon theology and philosophy. This work proposes that the Bible was an important and pervasive influence in Hawthorne's fiction. The Bible provides Hawthorne with numerous resources for both his artistic and moral concerns. At a basic level the Bible provides a popular platform that allows Hawthorne to immediately connect with his contemporary audience who were intimately familiar with the Bible. More importantly, though, are the vast examples and perspectives of the human condition and human …

Evaluation Of Low-Temperature Fluoride Routes To Synthesize Actinide Nitrides And Oxide Solid Solutions, Gunanda Waduge Chinthaka Silva

UNLV Theses, Dissertations, Professional Papers, and Capstones

Actinide mononitrides have been considered as a possible nuclear fuel for the Generation-IV nuclear reactor systems. In the process of evaluating these actinide mononitrides as nuclear fuel, it is important to study different chemical and physical characteristics of these compounds. Synthesis of the materials is thus important. Carbothermic reduction is one of the techniques that have been used to synthesize actinide mononitrides. In this method, a mixture of actinide oxide such as UO 2 and excess carbon is heat treated at temperatures greater than 1700 °C under a nitrogen atmosphere. The technique is however not promising in synthesizing the actinide …


The Sociology Of Scenes, The Sacramento Poetry Scene, Dana Nell Maher May 2009

The Sociology Of Scenes, The Sacramento Poetry Scene, Dana Nell Maher

UNLV Theses, Dissertations, Professional Papers, and Capstones

For this ethnography, I use my feminist perspective, grounded theory, participant observation, and autoethnographic techniques to explore an urban poetry scene. I suggest that scene studies are a viable alternative to community studies and that we move our articulation of social experience to reflect it as it occurs, on a multitude of continuums. My goal with this project is to develop, use, and discuss the utility of a definition of scene that is intended to be useful to scene studies researchers. To this end, I both evaluate an outdated definition of scene (Irwin 1973 & 1977), and define the three …

Distribution And Site Selection Of Le Conte's And Crissal Thrashers In The Mojave Desert: A Multi-Model Approach, Dawn Marie Fletcher

UNLV Theses, Dissertations, Professional Papers, and Capstones

Information on the distribution and habitat requirements of a species are critical components to the development of meaningful conservation plans. Such knowledge, however, is particularly difficult to obtain for species that are elusive and occur at low densities, such as the Le Conte's ( Toxostoma lecontei ) and Crissal (Toxostoma crissale ) thrashers. In association with a regional conservation plan, I evaluated the distribution and habitat selection of these thrashers within Clark County, Nevada in the eastern Mojave Desert. I used a call-broadcast approach to sample 432 stratified random locations, detecting Le Conte's thrashers at 45 locations and Crissal …

Molecular Epidemiology Of Methicillin-Resistant Staphylococcus Aureus (Mrsa), Ilene Bautista

UNLV Theses, Dissertations, Professional Papers, and Capstones

Staphylococcus aureus is a frequent cause of a myriad of infections in hospitals, healthcare facilities and community settings. It is often related to skin and soft tissue infection, but it can also cause other diseases varying from food poisoning to endocarditis and toxic shock syndrome. According to a study by Kuehnert et al. (2006) there has been a strong association between Staphylococcus aureus (S. aureus) carriage and risk factors for subsequent infections. Subsequent infection from S. aureus , including methicillin-resistant S. aureus (MRSA) infection, can be projected by looking at the presence of S. aureus nasal colonization. The purpose of …


The Relationship Between Benefit Satisfaction And Intent To Leave: A Study Of Finance Departments In Las Vegas, Jung-In Bae May 2009

The Relationship Between Benefit Satisfaction And Intent To Leave: A Study Of Finance Departments In Las Vegas, Jung-In Bae

UNLV Theses, Dissertations, Professional Papers, and Capstones

This study was conducted to examine the relationship between benefit satisfaction and intent to leave among employees who work in finance departments in Las Vegas hotels.

Employee benefits have generally been assumed to be an effective way to attract and retain employees; in fact, 70% of 45 U.S. companies include the benefit packages in their retention strategies. That idea that competitive benefits packages can help firms to win the retention war is widely accepted.

The results of the study indicate that benefit satisfaction was significantly related to intent to leave; those who were satisfied with benefits were less likely to …
