Channel modification has played a vital part in shaping the rivers and streams as
they are seen today. Channel modifications range from the construction of dams and levees
for flood control purposes to channelization of an existing meandering...
For complex classification systems, data is usually gathered from multiple sources of information that have varying degree of reliability. In fact, assuming that the different sources have the same relevance in describing all the data might lead to...
Within the Appalachian hills of eastern Kentucky, large-scale coal mining operations are directly altering the headwater landscape through the construction of hollow fills. These man-made landforms and their associated in-stream structures alter a...
Many important applications require the discovery of items which have occurred frequently. Knowledge of these items is commonly used in anomaly detection and network monitoring tasks. Effective solutions for this problem focus mainly on reducing...
Stream riparian zones are ecotones between terrestrial and aquatic environments. Studying these areas in urban environments is important since they lie adjacent to stream water supplies. I conducted a study of riparian woody and groundcover...
This thesis looks at the optimization of fluid flow and mass transfer using computational fluid dynamics (CFD) in a micro fluidic coulter counter. CFD will be used to solve equations of fluid flow and mass transfer to see how molecules within the...
Transportation--Kentucky--History; Kentucky. Board of Internal Improvement--History
For a brief period of fifteen years, the Board of Internal Improvement occupied a place of prominence in the political and economic affairs of Kentucky. From its
creation in 1835, until the revision of the constitution in 1850, the board spent vast...
This thesis is an examination of the viability of a low pH hydrogen peroxide scrubbing process for removing H 2 S acid gas present in typical biogas streams generated from dairy farm anaerobic digesters. Biogas ranges in composition based on the...
Few previous studies have compared microbial communities in subterranean and surface environments. Chemical analyses used to characterize the surface and cave microbial environments indicated limited exchange between surface and subsurface waters....
This work develops a method of estimating peak daily streamflow, Qpeak, for Kentucky streams using daily average streamflow, Qave, data from the United States Geological Survey's (USGS) National Water Information System (NWIS) website. The purpose...
Freshwater mussels--Ecology; Freshwater mussels--Blue River (Ind.)
This study assessed life history components for the elephantear freshwater mussel, Elliptio crassidens (Lamarck, 1819). The main focus of this study was to determine the suitability of various fish species as a host for E. crassidens and to...
Electronic commerce--Corrupt practices--Prevention; Internet advertising--Corrupt practices; Internet fraud
Online search advertising is currently the greatest source of revenue for many Internet giants such as Google™, Yahoo!™, and Bing™. The increased number of specialized websites and modern profiling techniques have all contributed to an...
A novel catalyst with hydro-desulfurization and hydrogenation capabilities was tested with the aim of producing ultra-low sulfur and aromatics diesel oil. The catalytically active phase is nickel in a reduced valence state on a carrier made of zinc...
Public administration--Decision making; Political planning--United States--Case studies; Bankruptcy--United States
The purpose of this study is to analyze two Congressional decisionmaking models and two policymaking models to identify which provides the strongest explanation of the bankruptcy reform process between 1997 and 2005. The two models of Congressional...
The purpose of the present study was to examine the relationship among organizational justice components, overall job satisfaction, and organizational commitment within the intercollegiate athletics setting. Perceptions of three organizational...
This thesis lays the groundwork for creation of a graduate-level computer forensics course. It begins with an introduction explaining how computing has invaded modern life and explains what computer forensics is and its necessity. The thesis then...
In 2003, Wilson Creek running through Bernheim Arboretum and Research Forest in central Kentucky was restored to its original winding path through a valley field. Early 20th century settlers had previously redirected this creek to run a straight...
This dissertation explores the physical and biological factors that control zooplankton population growth rates in the Ohio River (USA). I employed both observational studies and a mesocosm experiment to ascertain zooplankton population and...
Trees in cities--Kentucky--Louisville; Urban forestry--Kentucky--Louisville; Louisville (Ky.)--Environmental conditions
Trees in urban residential neighborhoods provide valuable ecosystem services. Urban trees also face threats from disturbances, such as storms. In 2008, the Urban Forest Effects model was used to estimate abundance and species composition of...
Mixing machinery; Production engineering--Case studies
A processing facility in Trenton, Ky owned by HydroSolutions is in need of modernization in order to increase efficiency in the mixing process, improve the safety of the facility, and give the facility the ability to expand in the future. The main...
