Effect Of Atmospheric Variations On Subsurface Flow And Transport, Laila Badran
UNLV Retrospective Theses & Dissertations
This thesis investigates the effect of atmospheric variations on subsurface flow and transport at the proposed high level waste repository at Yucca Mountain, Nevada. The conditions of subsurface transport were simulated with NUFT (Nonisothermal Unsaturated-Saturated Flow and Transport model) modeling software developed by the Lawrence Livermore National Labs (Nitao, 1995). Rock properties and surface ambient conditions specific to the mountain, including diurnal and seasonal changes in temperature, pressure and humidity were incorporated into the NUFT model. The effects of changing atmospheric conditions on the liquid and vapor phase components and fluxes were examined as well. Time swing analysis of weather …
Modeling The Rates Of Lead And Strontium Uptake By Zeolitized Tuff From Rainier Mesa, Nevada Test Site, Nevada, Patricia Ann Bernot
Modeling The Rates Of Lead And Strontium Uptake By Zeolitized Tuff From Rainier Mesa, Nevada Test Site, Nevada, Patricia Ann Bernot
UNLV Retrospective Theses & Dissertations
The fate and transport of contaminants released during nuclear testing at the NTS are partly controlled by interactions of their aqueous species with mineral surfaces. It has been shown that retardation of contaminants in the subsurface may be controlled by intraparticle mass transfer rather than equilibrium partitioning. For this reason, the rate of lead (Pb) and Strontium (Sr) uptake by zeolitized tuff from Rainier Mesa, NTS, was studied as a function of pH, ionic strength, and metal concentration; To test the hypothesis that sorption of Pb occurs through surface precipitation and Sr sorbs through diffusion, the data were modeled by …

Hydrogeology Of The Penoyer Valley Region, Central Nevada, Douglas Bruce Blatchford
UNLV Retrospective Theses & Dissertations
Groundwater in the vicinity of Penoyer Valley in central Nevada is part of the White River Flow system that drains from Jakes Valley in the north to Muddy River Springs in the south, a distance of 320 km (200mi). A four-basin subregion was modeled that indicates Penoyer, Garden, Coal, and Tikaboo Valleys are hydraulically connected. This connection is facilitated by carbonate rock formations found in the Worthington Mountains and the Timpahute Range, located on the eastern and southern perimeter of Penoyer Valley. Although Penoyer Valley and Garden Valley are hydraulically connected, it is likely that groundwater does not flow across …

Measuring Efficiency In The Clark County Hotel Casino Industry, Daniel Encinoza
Measuring Efficiency In The Clark County Hotel Casino Industry, Daniel Encinoza
UNLV Retrospective Theses & Dissertations
The analysis and comparison of productivity in the service sector have proven to be difficult. Nevertheless, the Tomqvist index of relative productivity used in this study allows me to compare the relative productivity of different hotel-casino properties, while avoiding the usual problems that arise when measuring efficiency in service industries. This empirical study illustrates the efficiency of index numbers in evaluating relative efficiency. The simplicity of the model and its ability to evaluate all aspects of the production process, including economies of scale, renders this methodology far superior to the use of direct indexes. From calculations included in the study, …

Suicide In The Las Vegas Homeless Population: Applying Durkheim's Theory Of Suicide, Joseph Dean Diaz
UNLV Retrospective Theses & Dissertations
This study is an empirical test of Durkheim's theory of suicide. Durkheim's 1897 theory holds that suicide is caused not by environmental or physiological forces, but by social forces, which either push to the individual to take his or her own life, or fail to prevent suicidal behavior; The population from which the data were gathered for this study was the Las Vegas homeless population. The lack of social bonds and social integration, which Durkheim found to be related to suicide, are generally present in homeless persons. Therefore, it was suspected that factors which contribute to homelessness would be positively …
