An Exploratory Study On Energy Consumption Of Energy Star And Non-Energy Star Homes, Prajakta Kulkarni

UNLV Theses, Dissertations, Professional Papers, and Capstones

The reduction of energy consumption is one of the economic necessities in the United States due to depleting energy sources in the world. The construction industry is stepping forward to reduce the energy consumption of buildings by efficient designs or by constructing buildings with energy efficient materials and features. In 1992, the U.S. Environmental Protection Agency (EPA) and Department of Energy (DOE) introduced the Energy Star Program to promote energy efficient products with the same or improved services. According to the EPA, Energy Star homes, which use these products, will consume 20 to 30 percent less energy than non-Energy Star …

Petrogenesis Of The Greenwater Range: Comparison To The Crater Flat Volcanic Field And Implications For Hazard Assessment, Ashley Kaye Tibbetts

UNLV Theses, Dissertations, Professional Papers, and Capstones

Pliocene basalts of the Greenwater Range, California erupted from 24 volcanic vents now represented by volcanic plugs, craters and scoria mounds. Basaltic magmas originated in the asthenospheric mantle, but show evidence of a lithospheric component. Depths and temperatures of melting calculated using a silica activity geobarometer are 54.3–89.6 km and 1367-1435oC, placing melting in the asthenosphere. The preferred petrogenetic model involves melting of lithospheric mantle thermally and mechanically, but not chemically, converted to asthenospheric mantle. Melting depths correspond to low velocity zones in the mantle as revealed in seismic profiles. Chemical and lithologic similarities between basalt in the Greenwater Range …

Factors Influencing Attitudes Towards Prostitution, Brian Robert Brehman

UNLV Theses, Dissertations, Professional Papers, and Capstones

The purpose of this study was to examine the factors that influence attitudes towards prostitution. Students from University of Nevada, Las Vegas and University of British Columbia (N=591) were compared based on their responses to the Attitudes Towards Prostitution (ATP) Scale and by demographic differences. Analysis of variance (ANOVA) identified significant differences in ethnicity, religiosity, and certain sexual experiences. Regression analysis revealed location of students and religiosity were significant predictors of attitudes.

Characteristics Of Adolescent Females Sexually Exploited Through Prostitution, Alanna Robinson

UNLV Theses, Dissertations, Professional Papers, and Capstones

Adolescent females are becoming the fastest growing population amongst juveniles being held in detention and referred to juvenile courts. Unfortunately such increases are linked to a lack of alternative services available for youths during the adjudication process. Upon being arrested, delinquent girls are suffering from a host of health, emotional and social issues for which there is also a lack of programming and detailed research. However, emerging evidence indicates that female delinquency is characterized by a multitude of overlapping problems that distinguish them from male delinquents. Issues include poor mental health, history of child abuse, substance abuse among parents and …

Retrofitting Existing Commercial Buildings In The Desert Southwest To Be Energy Efficient, Andrea Lee Wilkins

UNLV Theses, Dissertations, Professional Papers, and Capstones

This research proposes recommendations specific to the desert southwest for retrofitting existing commercial buildings. A dry, arid region such as Las Vegas, Nevada must contend with different ecological concerns than other parts of the United States. The city of Las Vegas sits in a valley in the Mojave Desert of the Southwestern United States and has a population of over 2.5 million inhabitants. The Las Vegas summers are rather hot and frequently exceed 100 degrees F, while the winters are usually mild, about 60-70 degrees F with cool nights. The state of Nevada receives an average of four inches of …

Phyllosilicate Mineralogy, 40ar/39ar Geochronology, And Genesis Of Petrocalcic Soils In The Southwest U.S.A., Colin R. Robins

UNLV Theses, Dissertations, Professional Papers, and Capstones

Obtaining isotope ages for arid soils and paleosols, including carbonate-cemented (calcic and petrocalcic) horizons, constitutes a significant challenge for soil scientists, geomorphologists, and stratigraphers. Carbonate-cemented soils foster diverse suites of authigenic minerals with exciting potential for geochronology, however, this potential has not been realized. This dissertation describes the timing of pedogenic palygorskite and sepiolite crystallization in extremely old, extant petrocalcic soils of the southwest U.S.A., and assumes that these fibrous, high-magnesium phyllosilicates contain sufficient lattice-bound K to warrant vacuum-encapsulated 40Ar/39Ar geochronology. This three-part study evaluated the (1) selective extraction, (2) 40Ar/39Ar analysis, and (3) pedogenesis of palygorskite and sepiolite.

Oral Cancer In Nevada: A Public Health Perspective, Karl Kingsley

UNLV Theses, Dissertations, Professional Papers, and Capstones

Cancer is the second leading cause of death in the United States, and oral cancer remains the eighth leading cause of cancer death among US males. Although previous epidemiologic studies have found that overall rates of cancer, including oral cancer, have declined in the US in recent decades – these declines are neither uniform nor consistent within this population. Anecdotal evidence has suggested that rates of oral cancer in Nevada are relatively high, although no evidence was available to support these assertions.

Oral Cancer Epidemiology: Based upon this information, a detailed and thorough epidemiologic examination of oral cancer rates in …

An Evaluation Of Lead In Imported Candies Within Clark County, Nevada, Usa, Lee Reuben Ibarra

UNLV Theses, Dissertations, Professional Papers, and Capstones

Imported candies from Latin America pose a danger to children because of the potential for those candies to contain harmful levels of lead. This study sought to identify characteristics of imported candies that typically display higher concentrations of lead. This study also explored the Integrated Exposure Uptake Biokinetic model developed by the EPA. Using lead exposure data specific to Clark County, Nevada, the IEUBK model was used to estimate the amounts of candy a child would have to consume in order to raise his blood lead level to over 10µg/dL (the federal allowable limit).

The results showed that candies with …
