Design And Analysis For Melt Casting Metallic Fuel Pins Incorporating Volatile Actinides, Xiaolong Wu
Design And Analysis For Melt Casting Metallic Fuel Pins Incorporating Volatile Actinides, Xiaolong Wu
UNLV Theses, Dissertations, Professional Papers, and Capstones
Fundamental issues related to the selection of a metallic fuel casting furnace design are presented and discussed including heating mechanisms, casting issues, crucible design, and issues related to the mass transport of americium. The process of evaluating all of these different criteria is undertaken to select a concept that would have the greatest chance of success for casting americium in a metallic fuel rod. Based on this evaluation process, a concept for the casting of metallic fuel pins containing high vapor pressure materials is selected and discussed. The important physics of this concept include mass transport of americium from the …
The Impact Of Air Quality On The Selection Of A Home, Carol Lane
The Impact Of Air Quality On The Selection Of A Home, Carol Lane
UNLV Theses, Dissertations, Professional Papers, and Capstones
Hedonic price method studies have assumed that individuals consider air quality as a characteristic of their homes. The purpose of this study is to determine if air quality is a significant characteristic considered when an individual decides where to live. This study uses a survey to determine where air quality ranks amongst the different characteristics of a home. My results show that air quality is significant but ranks below structural and neighborhood characteristics.
A Study Of Obstacles To Use Of Methane Gas Produced In Landfills For Energy, Sharee Lynn Bowdidge
A Study Of Obstacles To Use Of Methane Gas Produced In Landfills For Energy, Sharee Lynn Bowdidge
UNLV Theses, Dissertations, Professional Papers, and Capstones
The purpose of this study is to examine why landfill generated methane gas is not being treated as a resource, and used more widely as an energy source in the Southwestern United States. In this thesis, I have identified four possible barriers that may describe why this resource is not being used more often at landfill operations: 1) technological difficulties, 2) economic limitations, 3) regulatory constraints, and 4) insufficient desire to use. I have explored each of the possibilities in depth through case study interviews with individuals employed at six landfill operations, and individuals associated with landfill policy making. Although …
An Economic Analysis Of The Arsenic Standard On Nevada, Jill S. Dale
An Economic Analysis Of The Arsenic Standard On Nevada, Jill S. Dale
UNLV Theses, Dissertations, Professional Papers, and Capstones
In 2001, the arsenic standard for drinking water was lowered from 50 parts per billion to 10 parts per billion. The clean-up costs for Nevada are estimated at approximately 400 million dollars. The purpose of this project is to examine the economic impacts the State of Nevada will absorb as a result of the new regulation. Research of historical data will be the basis for the project. National data from the U.S. Environmental Protection Agency and data collected from the State of Nevada will be accompanied by comparable research data found through other sources
Coastal Resort Development And Impacts On Shallow Water Aquifers In Southern Baja California, Sur. Mexico, Bud J. Bennenman
Coastal Resort Development And Impacts On Shallow Water Aquifers In Southern Baja California, Sur. Mexico, Bud J. Bennenman
UNLV Theses, Dissertations, Professional Papers, and Capstones
A Coastal resort named Fiesta Surf is being planned for the southern portion of the Baja peninsula on the Pacific coast between the resort town of Cabo San Lucas and Todos Santos. Two additional resorts and an exclusive housing community are in the planning stages within this region, known as the "Pacific Corridor." The proposal for development is in a high growth region near the southern tip of the Baja peninsula in the state of Baja California, Sur, Mexico. The Pacific coast of southern Baja has seen little development and consists largely of non-developed shoreline. The current economic base of …
Mosquito Population Dynamics During The Establishment Phase Of A Constructed Desert Wetland, April Newman
Mosquito Population Dynamics During The Establishment Phase Of A Constructed Desert Wetland, April Newman
UNLV Theses, Dissertations, Professional Papers, and Capstones
The Nature Preserve at the Clark County Wetlands Park is a constructed wetland that has the potential to produce new mosquito habitat. This thesis evaluates the potential for the development of a mosquito problem at the newly constructed wetland system by assessing the population dynamics of mosquitoes within the Nature Preserve. Based on data collected from May 2001 through January 2002, I describe fluctuations in mosquito genus and relative abundance during the first summer through winter period of wetland development.
