Forensic Soil Analysis: Characterization Of The Sand Fraction, John Baize
Forensic Soil Analysis: Characterization Of The Sand Fraction, John Baize
Masters Theses & Specialist Projects
The purpose of this project was to develop a comprehensive analytical method for the characterization of soil by examining particle size, elemental composition, and percent organic matter in soil, and to determine its forensic applicability. In this study, five soils of varying geological locations were examined including two samples from Kentucky; two samples from Pennsylvania; and one from Washington D C A Gilson sonic sieve shaker was used to separate fractions of soil to determine particle size, and a JEOL scanning electron microscope with a Kevex EDS detector was used to determine elemental composition. These techniques coupled with percent total …

Development Of An Atmospheric Fluidized Bed Combustor (Afbc), William Orndorff
Masters Theses & Specialist Projects
The relatively recent interest in the U.S. in the development of atmospheric fluidized bed combustion (AFBC) has been preceded by two main factors. First of these is the ever present problem of acid rain and growing public support for cleaner burning fossil fuels. Second is the increasing demand on public landfills and subsequent need for burning of municipal solid waste. From these factors and their corresponding influences, Western Kentucky University has the impetus and has received the financial assistance necessary to build and develop a laboratory scale AFBC system. A brief history of the events leading to this development, as …
Mathematical Modeling Of Convective Heat Transfer In Mammoth Cave, Jonathan Jernigan
Mathematical Modeling Of Convective Heat Transfer In Mammoth Cave, Jonathan Jernigan
Masters Theses & Specialist Projects
Around two centuries ago, changes were made to the entrances of Mammoth Cave and its passages. Today the Historic Entrance to Mammoth Cave is enlarged and the passage just beyond the entrance known as Houchins' Narrows has been cleared of rubble and filled with sediments. These enlargements have resulted in an increase in airflow throughout the Historic Section of the cave causing environmental conditions such as air temperature and airflow to fluctuate. These fluctuations have negatively impacted inhabitants and contents of the cave system. To restore natural conditions within the cave, Science and Resource Management personnel at Mammoth Cave National …
The Effects Of Hydrilla Infestation On Selected Wintering Waterfowl: Santee Copper Lake System, South Carolina, William Davis
The Effects Of Hydrilla Infestation On Selected Wintering Waterfowl: Santee Copper Lake System, South Carolina, William Davis
Masters Theses & Specialist Projects
Hydrilla is an exotic aquatic weed that was introduced into Florida in the 1950's. Since that time it has spread rapidly from lake to lake throughout the southeast and beyond. The Santee Cooper lake system in eastern South Carolina was infested with the weed in the early 1980's. Since that time lake managers have sought ways to eliminate the aquatic plant and have succeeded to a great extent through the use of sterile grass carp as a biological control agent. This paper, however, contains evidence to support the view that hydrilla is actually a beneficial habitat for many species on …
Evaluation Of Continuous Flow Constructed Wetlands Treating Swine Waste, Stephanie Rivard
Evaluation Of Continuous Flow Constructed Wetlands Treating Swine Waste, Stephanie Rivard
Masters Theses & Specialist Projects
The ability for wetlands to purify contaminated water is not a new concept. Natural wetlands have been cleansing water within our environment for ages. After studying the process of natural wetlands the same concept was applied to municipal waste. It is the success of constructed wetlands treating municipal waste that created the new idea for the application of a wetland system to treat wastewater from livestock facilities. Through proper design and management, constructed wetlands may be useful for reducing the nutrient concentration of waste (Rieck el al., 1996). Taking into consideration the higher nutrient loads of livestock waste, the same …
