Disseminated Tuberculosis In Captive Malayan Tapir (Tapirus Indicus), Theerayuth Kaewamatawong, Wijit Banlunara, Anudep Rungsipipat, Nopadon Pirarat, Suphasawatt Puranaveja, Angkana Sommanustweechai

The Thai Journal of Veterinary Medicine

Tuberculosis caused by Mycobacterium tuberculosis is an important zoonotic disease that concerns the survival of endangered species and public health aspects. A 17-year-old, female Malayan tapir from a zoo in Thailand died with a sign of panting after anesthesia for the treatment of her oral problems. Grossly, multiple caseous white nodules were scattered throughout the parenchyma and bulged from the capsular surface in affected organs such as lung, lymph node and liver. Histologic examination revealed multifocal to coalescing granulomas characterized by caseous necrotic center, loosely organized inflammatory zone with low numbers of Langhans’s giant cells and thin fibrotic zone. A …

Comparative Study Of Temperatures Used In Silicone Impregnation Of Porcine Hearts Plastination, Damri Darawiroj, Adisorn Adirekthaworn, Sayamon Srisuwattanasakul, Kongkiat Srisuwattanasakul

The Thai Journal of Veterinary Medicine

Forced impregnation process is normally performed under vacuum at freezing temperature which requires expensive plastination apparatus. To reduce the cost in the plastination process, forced impregnation of porcine hearts under two different environments, which are at the freezing temperature (-20oC) and at room temperature (22-25oC), was compared. Twelve porcine hearts were collected from a slaughter house, and divided into the groups, six in each, and subjected to be plastinated by S10 standard technique at the two temperatures. Although the forced impregnation at room temperature, also the curing process, was more time-consuming, all hearts from both groups produced satisfying plastinated specimens. …

Space And Power In The Ivory Tower: Decision Making In Public Higher Education, Sandra Mccoskrie Blanchette

Graduate Doctoral Dissertations

The challenges of managing physical space in public higher education are often left unspoken and under researched. In this multiple case study of three urban universities, decision-making processes are examined with particular attention to who has institutional decision-making authority. Effective and efficient space management is important because the use of space on campus can contribute to research and practice by promoting innovation and collaboration or can isolate individuals and departments in silos. This study identifies three distinct challenges related to space management on campus: the quality of space, the location of space, and the quantity of space. The research findings …

Active Bundles For Protecting Confidentiality Of Sensitive Data Throughout Their Lifecycle, Lotfi Ben Othmane

Dissertations

Protecting confidentiality of shared sensitive data requires satisfying conflicting needs for disseminating data and preventing unauthorized data disclosures. We propose a solution named the active bundles scheme for protecting sensitive data from their disclosures to unauthorized parties during their dissemination. The scheme protects data throughout their entire lifecycle, from data creation through their dissemination to their evaporation or apoptosis (a partial or complete self-destruction, respectively).

An active bundle packages together sensitive data, metadata, and a virtual machine (VM) specific to the bundle. Metadata contain information related to the use of data, including data access control and dissemination policies. A VM …

An Investigation Of Sustainable Environmental Practices And Consumer Attitudes & Behaviors Toward Hotel Bathroom Amenities, Edward James Bobbett

UNLV Theses, Dissertations, Professional Papers, and Capstones

In the 1980s hotel operators became concerned with greening and sustainability. It was at this time the hospitality industry began focusing on energy efficiency and the sustainable development of tourism (Chan & Lam, 2001; Welford, Ytterhus, & Eligh, 1999). Since then, a global trend has emerged as hotels introduce programs to reduce the amount of resources used and the overall environmental impact they have on the planet, or their carbon footprint. The hospitality industry has introduced programs such as recycling in both the front and back of the house, energy-efficient lighting, towel re-use programs, linen exchange programs, Green Certifications, and …

A Case Study Of Pay-For-Performance Compensation Programs, Eric Berman

UNLV Theses, Dissertations, Professional Papers, and Capstones

A well conceived pay-for-peformance program that aligns measurable financial and non-financial results with the companies publicly stated goals can create synergy in regards to productivity, efficiency and competition. The problem with some pay-for-peformance programs is that they can be poorly conceived, measure outcomes improperly, administered inconsistently or reward an unethical result. A balanced scorecard approach to pay-for-peformance programs can measure both hard and soft metrics that lead to both company and manager/employee success.

Transcriptional Regulation Of Shigella Virulence Plasmid-Encoded Genes By Virb And Crp, Christopher Thomas Hensley

UNLV Theses, Dissertations, Professional Papers, and Capstones

Shigella flexneri is a species of Gram-negative intracellular pathogens that causes bacillary dysentery in humans. Shigella relies on the precise transcriptional regulation of virulence genes, encoded by a large virulence plasmid, for invasion and infection of human colonic epithelial cells. The transcription of most identified virulence genes are regulated through a cascade controlled by the primary regulator of virulence genes, VirF, and the global transcriptional regulator, VirB. Currently, few studies have addressed how individual Shigella virulence genes are precisely regulated for optimal expression during specific stages of pathogenesis and within the constraints of the regulatory cascade. This work addresses how …

The Gendering Of Nevada Politics: The Era Ratification Campaign, 1973-1981, Caryll Batt Dziedziak

UNLV Theses, Dissertations, Professional Papers, and Capstones

This dissertation examines Nevada‟s Equal Rights Amendment ratification campaign spanning from 1973 through 1981. Using legislative records, newspapers, archival records, oral histories and interviews; this work traces the creation of two distinct political cultures that arose in Nevada during this period. Women from both sides of this debate sought to make themselves heard in the political deliberations over this proposed amendment; thus finding new agency with which to express their political views. As ERA activists led a grassroots campaign for equality under the law, conservative women mobilized existing church networks to effect a massive counter attack. In the end, while …

Composite Of Complexity: Manifestations Of Whiteness And Class Among Las Vegas Italian Americans, Danielle Nicole Axt

UNLV Theses, Dissertations, Professional Papers, and Capstones

Conventional terminology and conventional boundaries, in regard to ethnicity, are no longer applicable to the ever shifting population of the United States. In specific, the various degrees of White ethnic identity does not easily transition into convenient all encompassing categories such as Caucasian or more simply, White. Whiteness studies have been at the forefront of this critique, most recently asserting that White ethnic identity is heavily influenced by context. However, although many studies are now recognizing the impact of multiple layers of White ethnic identity (along the lines of gender, locale, socioeconomic level etc.) many still neglect to identify a …

Analyzing The Impact Of Reactive Transport On The Repository Performance Of Triso Fuel, Gregory Schmidt

UNLV Theses, Dissertations, Professional Papers, and Capstones

One of the largest determiners of the amount of electricity generated by current nuclear reactors is the efficiency of the thermodynamic cycle used for power generation. Current light water reactors (LWR) have an efficiency of 35% or less for the conversion of heat energy generated by the reactor to electrical energy. If this efficiency could be improved, more power could be generated from equivalent volumes of nuclear fuel. One method of improving this efficiency is to use a coolant flow that operates at a much higher temperature for electricity production. A reactor design that is currently proposed to take advantage …

Evaluating The Energy And Carbon Footprint Of Water Conveyance System And Future Water Supply Options For Las Vegas, Nevada, Eleeja Shrestha

UNLV Theses, Dissertations, Professional Papers, and Capstones

Water production requires the use of energy to transport water from distant locations, pump groundwater from deep aquifers and treat water to meet stringent drinking water and wastewater regulations. Energy production based on its source involves the emission of greenhouse gases also known as carbon footprint, which is the leading cause of global warming and climate change. Because of growing concerns of global warming due to these emissions, water providers are required to analyze the energy and associated carbon footprint of existing water production facilities and future water supply options. A system dynamics model is developed to estimate the energy …

Physiological Implications Of Natural Versus Induced Arousal From Torpor, Jenifer C. Utz

UNLV Theses, Dissertations, Professional Papers, and Capstones

During the hibernation season, animals oscillate between periods of torpor and periods of interbout arousal (IBA). During torpor, body temperature is often near 0° C and metabolism is severely depressed. Oxygen consumption, a proxy for aerobic metabolism, may fall to 1% of active values. Many physiological processes including cardiovascular, respiratory, and cellular functions nearly cease. During the IBA, euthermic body temperature is restored and most systemic and cellular processes function at fully active levels. The transition period between these two physiologically dissimilar states is called arousal.

The rate of rewarming (RRW) during arousal was previously expected to progressively increase until …

The Relationship Between Fitness Level, Gender, And The Percentage Of Vo2 Max At Crossover, Christina Louise Pettigrew

UNLV Theses, Dissertations, Professional Papers, and Capstones

The “crossover” concept is a means of understanding fuel utilization over a range of exercise intensities. According to this concept, certain biochemical adaptations occur in a fit individual allowing for an increase in lipid oxidation. The present study examined whether there was a relationship between fitness level, gender, and the percentage of maximum aerobic capacity (VO2 max) at crossover. Twenty-five subjects age 18-40 participated in this study. Subjects were divided in half based on their fitness level. After completing a graded exercise test to exhaustion, the crossover point for each subject was determined relative to their VO2 max. A 2x2 …

The Determinants Of Colorectal Cancer Survival Disparities In Nevada, Lucas N. Wassira

UNLV Theses, Dissertations, Professional Papers, and Capstones

Different population groups across Nevada and throughout the United States suffer disproportionately from colorectal cancer and its after-effects. Overcoming cancer health disparities is important for lessening the burden of cancer. There has been an overall decline in the incidence of and mortality from colorectal cancer (CRC). This is likely due, in part, to the increasing use of screening procedures such as Fecal Occult Blood Test (FOBT) and/or endoscopy, which can reduce the risk of CRC mortality by fifty percent. Nevertheless, screening procedures are routinely used by only fifty percent of Americans aged fifty years and older. Despite overall mortality decreasing …

Rare Earth Element Transport In The Yucca Mountain Region, Liqiong Zhang

UNLV Theses, Dissertations, Professional Papers, and Capstones

In sync with environmental pollution of solutes in nature, from source, process to consequence, geochemical processes (leaching and sorption) and hydraulic transportation of the rare earth elements (REEs) have been investigated at Yucca Mountain (YM), Nevada. This research includes the leaching behavior of trace elements (including REEs) from aquifer rocks, the surface complexation reactions of REEs in synthetic groundwater, and transportation of reactive REEs in the local-scale groundwater system of YM. This dissertation includes three projects. These studies indicate that surface complexation reactions may retard the transportation of REEs along groundwater paths in YM, which suggests a similar behavior of …

Measurement System For High Pressure Characterizations Of Materials, Matthew K. Jacobsen

UNLV Theses, Dissertations, Professional Papers, and Capstones

Thermoelectric materials have long been investigated for possible use as power sources. This application was recently put to use in the Voyager space program, powering the deep space probes. Despite the usefulness of these materials, the use of pressure to investigate the material properties has only recently become interesting. As such, the work in this document was to developing a system for concurrently measuring the necessary properties. This system is capable of measuring the electrical resistivity, thermal conductivity, and Seebeck coefficient in the pressure range from 0 - 10 GPa. The results for zinc, almandine garnet, and nickel are presented …

Structures On A K3 Surface, Nathan P. Rowe

UNLV Theses, Dissertations, Professional Papers, and Capstones

In the first part of this paper, we examine properties of K3 surfaces of the form:

(x2 + 1)(y2 + 1)(z2 + 1) + Axyz − 2 = 0

We show the surface has Picard number q " 12 by finding 12 curves whose equivalence classes are linearly independent. These curves have self intersection −2. We find the lattice representations of the single-coordinate swapping automorphisms in x, y, and z. We show that we have enough of the Lattice to make accurate predictions of polynomial degree growth under the automorphisms. We describe these automorphisms in terms of operations on elliptic …

Classification Algorithms For Genomic Microarray, Rakesh Choudary Malepati

UNLV Theses, Dissertations, Professional Papers, and Capstones

The advent of new technologies like DNA micro-arrays provides scientists the ability to gather important information such as the expression levels of almost all the genes within a cell. As the collected data is huge, it is always necessary to use analytical methods to extract important information which can be useful in biological and medical applications. One of such applications is presented in (Van‟t Veer LJ 2002), where the authors used the gene expression values obtained from micro-arrays of breast cancer cells to predict the outcome of the disease. The prediction is based on a supervised classification. While the idea …

Bordered Identities: Class, Ethnicity, And Transnational Social Networks, Rayette Ellen Martin

UNLV Theses, Dissertations, Professional Papers, and Capstones

This thesis looks at the bordered identities of middle class second generation Mexican Americans in Las Vegas, Nevada. Through an analysis of the borderlands or gray spaces that occur at the intersections of class practices, transnational relationships and ethnic identities, participants’ bordered identities were found to be reinforced, contested, and generally negotiated. Participants’ identities are flexible; their expressed identities change in relation to context or situation. In the United States, Mexicans and Latinos more generally have been subjected to racial and ethnic oppression since the Mexican American war ended in 1848.This long history of discrimination has maintained perceptions that all …

From ‘Baggage’ To Not ‘Non-Persons’: Levy V. Louisiana And The Struggle For Equal Rights For ‘Illegitimate’ Children, Sherrie Anne Bakelar

UNLV Theses, Dissertations, Professional Papers, and Capstones

This study focuses on "illegitimate" children, who are more visible
than other children within the historical record because of the many laws
related to their existence. By examining this group of children, it is
possible to improve upon the framework that shapes our understanding
of childhood and provide a starting point for future studies that will
continue to illuminate children's history. Although illegitimacy laws are
as ancient as Western civilization, the key moment for the United States'
laws related to nonmarital children came in the spring of 1968 and the
pivotal decision of Levy v. Louisiana, 391 U.S. 68 (1968). …
