UNLV Theses, Dissertations, Professional Papers, and Capstones

Solar energy is the most sustainable source of energy available. However, solar applications such as photovoltaic cells represent only a partial solution to weaning our dependence upon fossil fuels. Several methods of storing solar energy are currently being pursued, and chemical storage stands out as a promising option - combining design simplicity with high energy density, with hydrogen being particularly attractive because of its abundance and inherently clean nature. A monolithic Photoelectrochemical (PEC) device that produces hydrogen by electrolyzing water directly from sunlight has the benefit of utilizing "free" solar energy to drive the reaction.

Although α-Fe 2 O 3 …

Evaluation Of Rapid Electric Battery Charging Techniques, Ronald Baroody

UNLV Theses, Dissertations, Professional Papers, and Capstones

Battery powered electric vehicles are gaining popularity worldwide. This is trend is driven by several factors including the need to reduce air and noise pollution, and dependence on fossil fuels. The main drawback of today's electric vehicle is its limited range, and the long time duration that is required to charge the electric batteries. This thesis addresses the latter problem.

In recent years, significant progress (through research and development) has been made to accelerate the charging time of the electric vehicle batteries through pulse charging rather than supplying continuous current and/or voltage. Some patented fast charging techniques demonstrated reduced charging …

Predisposition Factors Of Career And Technical Education Transfer Students: A Hermeneutic Phenomenology Study, Warren Glen Hioki

UNLV Theses, Dissertations, Professional Papers, and Capstones

Various econometric, sociological, and combined research models (e.g., Hossler and Gallagher's preeminent Three-Phase Model on College Choice) provide help in understanding high school students in their decision-making stages and college experience. Many studies that utilize these models on college choice strongly substantiate and perpetuate the long-standing dichotomy between students who aspire to attend college in pursuit of upward mobility through the traditional baccalaureate pathway versus a community college Career and Technical Education (CTE) pathway. High school students' aspirations to attend a 4-year institution, and more recently, the community college, are a focal point.

A review of the literature as it …

UNLV Theses, Dissertations, Professional Papers, and Capstones

I will create a transcription for wind ensemble of the "Overture to The Magic Flute " by WA Mozart. By completing this transcription, a standard orchestral work will be available in comparable quality and difficulty for wind ensemble. Although several simplified and one large concert band transcriptions have been made available during the 20th century, these arrangements were not consistent with late 18th century ideals of size and balance. This transcription will remain loyal to the original work through embracing the ideology of the 18th century musical mind. Through treatises, period writings and performance practice of Mozart's time, I will …

Analysis Of A Caliche Stiffened Pile Foundation, Richard C. Stone Jr.

UNLV Theses, Dissertations, Professional Papers, and Capstones

Cemented carbonate deposits (known locally as "caliche") in Las Vegas have been used to support shallow and deep foundations with relatively high bearing pressures compared to soil. Most high rise structures in Las Vegas are founded on either a large mat or a long pile foundation. Recently, a new foundation type consisting of a short pile system bonded to shallow cemented layers was utilized for a large high rise building in Las Vegas and settlements during construction were recorded. The bonding of caliche layers together with short piles forms a caliche stiffened pile (CSP) foundation. The CSP foundation is unique …

Quantity-Based Cost Forecasting System For Street Construction Projects, Nipesh Pradhananga

UNLV Theses, Dissertations, Professional Papers, and Capstones

Construction projects typically are not withdrawn after going into the competitive bidding process. The decision of contracting authorities regarding which projects will proceed to the bidding stage depends, in part, upon the early estimates of probable cost. Efforts are made to make this estimate as realistic as possible. Irrespective of the estimate of probable cost, the actual project cost is established by the amount of the winning bid.

This study analyzed historical bid data of street construction projects undertaken by the Public Works Department, Clark County, Nevada, from 1991 through 2006. The focus of this study was on utilizing statistical …

Systematic Analysis Of Identifying Key Dimensions Of Environmentally And Socially Responsible Hotels, Courtney Suess

UNLV Theses, Dissertations, Professional Papers, and Capstones

Development in Southeast Asia involves making good decisions for the future, so the idea that good planning can ignore sustainability is something of an oxymoron. Good development has to be sustainable and we have reached a point where the old ways of tourism development are intolerable. For example, hotels spring up without planning for the future. This short sightedness means natural endowments, like coastlines, erode and forests are cut down, chasing away the wildlife; or cultural history in the form of temples, historic buildings, and sacred places are destroyed. Ironically, tourism development is eradicating the very forms of product that …

Experimental And Natural Variation In Hovering Flight Capacity In Bees, Hymenoptera: Apidae, Jason Thomas Vance

UNLV Theses, Dissertations, Professional Papers, and Capstones

In honey bees, the capacity for flight underlies many behaviors which impact fitness and longevity, such as the ability to forage or evade predators. However, flight capacity is not fixed across bees' lifespan, which is punctuated by a suite of physiological changes that accompany age and the transition from in-hive to foraging behaviors; thus, flight capacity may vary during periods of development, senescence, or in response to morphological damage such as wing wear. This dissertation describes the biomechanics and aerodynamics which contribute to the scope of honey bee flight performance, and investigates how age, behavioral development, and wing-wear affects flight …

From Feminism, Adam Strauss

UNLV Theses, Dissertations, Professional Papers, and Capstones

From Feminism means to emphasize a world-view rather than an a-priori eye towards women; the manuscript does occasionally strike a generic feminist-didactic mode, but for the most part its concerns are with humanity/ecology and gender goes un-marked or people are altogether absent. The world is various, and in terms of form, the poems in this book are rangy: sonnets, prose poems, serial fragments, free verse tercets, measured and rhymed tercets, couplets, over-the-top monuments to generation by rhyme. Unconventional use of white-space occurs fairly frequently. My thought is that having breaks in articulation in two places, not just the end of …

The Curious Case Of Jim Mcgreevey, Justin Eckstein

UNLV Theses, Dissertations, Professional Papers, and Capstones

This project examines the apologetic discourse surrounding James Edward "Jim" McGreevey's August 12, 2004 resignation as governor of New Jersey. A cursory reading of the allegations McGreevey faced reveals a curious incongruity between the initial accusations of corruption and his apologizing for being homosexual. In short, McGreevey stood accused of corruption for a number of terrible cabinet appointments. Yet, he apologized for being gay and having a "consensual" affair with his former director of Homeland Security, Golan Cipel. Through a close reading of the texts, I decipher how McGreevey's apology modified the public's understanding of the events that lead to …

A Church Without Walls: Finding Community In Central Christian Church's Online Campus, Kayla Jo Gilmore

UNLV Theses, Dissertations, Professional Papers, and Capstones

Churches today are expanding beyond the physical walls of a church building. They are now online and interactive. This study explores the differences and similarities of communities of online churches and their physical church locations. It incorporates Stanley Fish's interpretive community theory by looking at Thomas Lindlof's common elements of a community and characteristics of an interpretive community. Using an ethnographic approach, survey and interviews were conducted to collect the data. Conclusions include determining that Central's online and physical church communities are in fact interpretive communities and that the online church is not replacing the physical church, but supplementing it.

Paradigmatic Recrudescence: Classical Realism In The Age Of Globalization, Nerses Kopalyan

UNLV Theses, Dissertations, Professional Papers, and Capstones

The paradigm of classical realism has been the subject of extensive debate in the study of international relations. Its axiomatic suppositions, conceptual structures, theoretical framework, and analytical scope have made realism the subject of both genuine veneration and intense scrutiny at the hands of international relations scholars. This has had a three-fold effect on the evolvement of the paradigm: realism has been methodically revised by neorealists; realism has become a tool of analysis for revisionist non-realists; and realism has been marginalized and erroneously critiqued. The objective of this thesis is to demonstrate and prove the following four points. First, to …
