Phosphorus Transport And Distribution In Kentucky Soils Prepared Using Various Biochar Types, Anvesh Reddy

Masters Theses & Specialist Projects

Conserving the environment is an issue that is gaining popularity day by day. Phosphorus transfer from agricultural soils is an important environmental issue that is being closely observed as the transport of phosphorous to water bodies is adversely affecting water quality due to accelerated eutrophication. It is important to establish phosphorous models that accurately account for soil test phosphorous. Standard models like SWAT (Soil and Water Assessment Tool) and EPIC (Environmental Policy Integrated Climate) were designed for serving this purpose. They are now used as the basis for developing new models that can more accurately account for the phosphorus transport, …

Making Music Sustainable: The Case Of Marketing Summer Jamband Festivals In The U.S., 2010, Melissa A. Cary

Masters Theses & Specialist Projects

Commercial music festivals in the United States have been growing in popularity since the 1960s. Today, many weekend-long music festivals are annual events spanning a variety of genres and often occur at the same locations each year. My research compares and contrasts how jamband music festivals are marketed as sustainable events and attempts to determine how the advertised sustainable practices are implemented and utilized at selected jamband music venues. The jamband genre of music emphasizes musical improvisation and borrows from other styles of music: rock, electronic, jazz, blues, folk, and bluegrass.

In addition, any impacts these festivals have upon the …

Removal Of Heavy Metals From Drinking Water By Adsorption Onto Limestone With A Focus On Copper And Aluminum Applications, Swarna Latha Somasani

Masters Theses & Specialist Projects

Elevated levels of arsenic and other heavy metals like copper, aluminum, zinc, and selenium in drinking water are found to have deleterious effects on human health. Hence, finding methods for reducing their levels is critical. Iron-coated limestone is used as an adsorption material for the removal of heavy metals from drinking water. Removal of heavy metals by native or uncoated limestone was also observed and used for comparison to and evaluation of the improvement in removal efficiency from the ironcoated material. The removal efficiency with limestone was studied for different concentrations of heavy metals. Kinetic studies were done to determine …

An Examination Of White-Nose Syndrome Occurrence And Dispersal Patterns: Utilizing Global And Local Moran's I Analysis To Evaluate An Emerging Pathogen, Celia M. Davis

Masters Theses & Specialist Projects

In this research, a novel approach that utilizes Moran’s I statistical analyses to examine the spatio-temporal dispersal patterns of the White-Nose Syndrome currently affecting North American bat species is undertaken to further understand the disease transmission mechanism(s) of this emerging wildlife epidemic. White-Nose Syndrome has been responsible for in excess of five million bat deaths to date and has the potential to alter the ecological landscape significantly; however, due to a variety of factors, little research has been conducted into the patterns of infection on a national scale. Global and Local Moran’s I analyses were performed on the spatial-temporal variable …

Monitoring Photocatalytic Degradation Of X-Ray Contrast Media With Raman Spectroscopy, Sabina Salkic

Masters Theses & Specialist Projects

X-ray contrast media such as diatrizoate and iohexol have been found in wastewater and drinking water and are difficult to remove because they are resistant to water treatment processes. A removal process can be started with ultraviolet photocatalytic degradation of X-ray contrast media in the presence of titanium dioxide or other catalysts. Raman spectra of diatrizoate and iohexol were taken in an aqueous solution in the presence and absence of titanium dioxide during exposure to ultraviolet radiation. Raman intensity is directly proportional to concentration; therefore, we can measure the rate of the reaction based on changes in the Raman spectrum. …

Reducing Lead And Selenium From Drinking Water Using Limestone-Based Material, Sindhu Tumati

Masters Theses & Specialist Projects

Contamination of drinking water with metals is a major problem facing many areas of United States and the World. There is a need for an inexpensive remediation technology for the removal of metals in drinking water that can be applied to small rural water systems. This research will focus on the development of a process for removal of select metals from drinking water by limestone-based material. Metals in drinking water considered for this research include lead and selenium. Limestone-based material has demonstrated the potential to reduce select metals (lead, cadmium and arsenic) in drinking water, with the additional benefit of …
