Brief Overview of the Problem: The Environmental Protection Agency (EPA), a government funded agency, provides both legislative and judicial powers for emissions monitoring in the United States. The agency crafts laws based on self-made regulations...
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...
We formulate an integro-difference model to predict the growth and spatial
spread of a perennial plant population with an age-structured seed bank. We allow
the seeds in the bank to be of any age, producing an infinite system of equations.
The...
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)...
Children and war; World War, 1939-1945--Kentucky--Louisville; World War, 1939-1945--Indiana--Madison; Girls--Indiana--Madison; Girls--Kentucky--Louisville
This thesis presents the view of World War II, a watershed event in U.S. history, through the lenses of a group that is not normally called upon, that of young children. The war was viewed by and affected young girls differently than others....
Soon after the atomic theory was established, it was found that the plant uses as sources of food not only the air and water, but also different constituents of the soil, dissolved in the soil moisture—the mineral nutrients. Ashes of different...
Many species of fungi undergo a dimorphic transition to switch from a unicellular yeast-like growth form to a filamentous growth form. Ustilago maydis undergoes such a transition, in response to successful mating events and subsequent host cues, to...
General. – The Characaeae is the only extant family of an ancient and unique group of nonvascular aquatic plants which are classified as a separate division, the Charophyta (Groves and Bullock-Webster, 1920; Zaneveld, 1940; Imahori, 1954; Bold,...
Dimorphism is a highly conserved process in fungi in which a transition between a unicellular, yeast-like growth form and either a unicellular or multicellular, filamentous growth form occurs in response to several different environmental cues. The...
Ford Motor Company; Business logistics--Management; Production management; Manufacturing processes; Organizational change
For many years the concept of Lean Manufacturing has been applied in automotive development as a tool to refine the manufacturing practices to the greatest efficiency possible through waste reduction. Continuous Improvement is a quality innovation...
Contamination can be very difficult to remove from water. Once this water seeps into the ground, the difficulty grows exponentially. The Paducah Gaseous Diffusion Plant, located in Paducah, Kentucky, has contaminated the groundwater. The...
The management of power and the optimization of systems generating and using power are critical technologies. A new architecture is developed to advance the current state of the art by providing an intelligent and autonomous solution for power...
"School gardens are not intended to create gardeners or farmers but to afford the growing boy or girl an opportunity for many aided developments." In the school garden the children are taught by one who can inspire them with a love not...
Business logistics; Production management; Manufacturing processes; Industrial efficiency
In today's competitive business environment, companies face enormous pressure and must continuously search for ways to design new products, manufacture and distribute them in an efficient and effective fashion. After years of focusing on reduction...
Preventive maintenance is a broad term that encompasses a set of activities aimed at improving the overall reliability and availability of a system. Preventive maintenance involves a basic trade-off between the costs of conducting...
It is important to burn the air toxics and harmful gases which come from water and wastewater treatment processes. In common practice, instead of natural gas, digester gas is used for economical reasons. This burning process takes place in the...
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...
The Technical Advisory Group (TAG) of the Innovative Treatment Remediation Demonstration Program (ITRD) made technology recommendations after reviewing thirty in situ remediation technologies for implementation at the Paducah Gaseous Diffusion...
Due to the complex nature of interactions at the genomic level as well as the large number of proteins present in an organism, understanding the functions of various genes that are expressed is essential. Creating an analysis pipeline for Expressed...
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...
