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...
Twenty-six fossil assemblages of land and freshwater molluscs from the Pliocene to the present, were collected from locations near the town of Meade, Kansas, U.S.A. and were analyzed (along with the extant molluscan fauna of Meade County, Kansas)...
This thesis is a methodological analysis of fire locations in Canadian provinces
from 2001 to 2010. The research presented in this thesis highlights the dominant fire
types for each province. Accurately locating active fires and burned area is...
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...
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...
Human exposure to mercury has been shown to cause a number of adverse health outcomes, predominantly neurological effects. The developing fetus is most susceptible, and even low levels of exposure have been shown to produce nervous system deficits....
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....
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...
Vietnam War, 1961-1975--Tank warfare; Indochinese War, 1946-1954--Tank warfare; Armored vehicles, Military--Vietnam--History
This thesis is a chronological historical examination of armored cavalry doctrine and execution during the Vietnam War, with a focus on comparison of the armored cavalry's doctrinal missions of reconnaissance, security, and economy of force with...
City planning--Psychological aspects; City planning--Citizen participation
This dissertation examines the impact of complexity and familiarity on visual preference for two content domains defined as Neo-Traditional and Modern. This research has five main themes: (1) To determine if there is a method for community design...
Intelligent transportation systems; Air quality; Air--Pollution
Environmental or air quality impacts of Intelligent Transportation Systems (ITS)
are very difficult to measure. Some researchers have attempted to quantify the effects of
individual ITS application on emissions; yet, the effects of ITS as a whole...
Mixed media assemblage including: an old wooden door, black velvet, bricks, wooden table, leather stretched over an armature of metal and other material to form a female nude, human hair, gas lamp (bec Auer type), twigs, aluminum, iron, glass,...
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...
Naja kaouthia is a significant species because it feeds primarily on agricultural pests, causes human mortality, and is commercially exploited. Understanding the life history and demography of harvested populations is essential to providing...
In the age of high-throughput molecular biology techniques, scientists have incorporated the methodology of in-situ hybridization to map spatial patterns of gene expression. In order to compare expression patterns within a common tissue structure,...
Indians of North America--Kentucky--Bullitt County--Antiquities; Excavations (Archaeology)--Kentucky--Ashworth Rockshelter site; Ashworth Rockshelter site (Ky.)
Reinvestigation of a National Register property, the Ashworth Rockshelter (15BU236), northeast of Shepardsville, Bullitt Co., Kentucky, revealed stratified Early Archaic through Mississippian components (ca. 7900 B.C.-1500 A.D.). Primary occupation...
Urbanization disrupts natural soil profiles and as watersheds are
urbanized, their surfaces become impervious and this will result in
reduction of infiltration. For this reason, many cities are facing problems
with treating runoff water. Best...
Archaeologists use soil analysis to detect chemicals, like phosphate, to indicate areas of anthropogenic activity. Phosphate detection is a multi-step process, which makes standard techniques time consuming. Kinetic studies decreased the analysis...
Coal-fired power plants--Environmental aspects--United States; Mercury wastes--Environmental aspects--United States
This dissertation tests whether or not mercury emissions from electric power plants are not a significant contributor to mercury measurements in rainfall and argues that the current United States (U.S.) Environmental Protection Agency (EPA)...
