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,...
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)...
"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...
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...
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...
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...
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...
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...
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...
It is to be noticed that if there be any marshy places, certain animals breed there, which are invisible to the eye and yet getting into the system through the mouth and nostrils cause serious disorders." This quaint observation is taken from...
Leopold, Aldo, 1886-1948; Naturalists--United States--Biography; Wildlife conservation--Study and teaching (Higher); Ecology--Study and teaching (Higher)
This historic case study addressed the issue of the lack of citizen action toward environmentally responsible behavior. Although there have been studies regarding components of environmental responsible behavior [ERB], there has been little focus...
Ten algal isolates were obtained from soil into axenic culture and placed into defined media containing from 0 to 50 ppm of DDT, 2, 4-D,2,4,5-T, rotenone, or malathion (in two purities, 95 and 99%). For nine of the isolates, growth was measured...
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...
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....
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...
The acetogenin annonacin, from the tropical annonaceous plant Annona muricata, is a lipophilic, mitochondrial complex I inhibitor reported to be more toxic than rotenone to mesencephalic neurons. The temperate annonaceous plant Asimina tri/oba...
Vicinal dithioethers and alkenyl thioethers were synthesized under environmentally
friendly conditions using alkyne and thiol in water. Alkynes were also used to develop a
multibond-fonning reaction that fonned cyclic ketones or ketoesters through...
Gardeners--Kentucky--Louisville--Social conditions; Community gardens--Kentucky--Louisville
Using four surveys, two created by this researcher, another created by Walizcek, Mattson, and Zajicek, and a fourth created by Herbach, the researcher compared the characteristics of community gardeners, their motivations for gardening, and the...
Ozone forecast models using nonlinear regression (NLR) have been successfully applied to daily ozone forecast for seven metro areas in Kentucky, including Ashland, Bowling Green, Covington, Lexington, Louisville, Owensboro, and Paducah. In this...
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...
