Fractal Location And Anomalous Diffusion Dynamics For Oil Wells From The Ky Geological Survey, Keith Andrew, Karla M. Andrew, Kevin A. Andrew Dec 2009

Fractal Location And Anomalous Diffusion Dynamics For Oil Wells From The Ky Geological Survey, Keith Andrew, Karla M. Andrew, Kevin A. Andrew

Physics & Astronomy Faculty Publications

Utilizing data available from the Kentucky Geonet (KYGeonet.ky.gov) the fossil fuel mining locations created by the Kentucky Geological Survey geo-locating oil and gas wells are mapped using ESRI ArcGIS in Kentucky single plain 1602 ft projection. This data was then exported into a spreadsheet showing latitude and longitude for each point to be used for modeling at different scales to determine the fractal dimension of the set. Following the porosity and diffusivity studies of Tarafdar and Roy[1] we extract fractal dimensions of the fossil fuel mining locations and search for evidence of scaling laws for the set of deposits. The …

Using Conservative And Biological Tracers To Better Understand The Transport Of Agricultural Contaminants From Soil Water Through The Epikarstic Zone, Brian Ham Dec 2009

Using Conservative And Biological Tracers To Better Understand The Transport Of Agricultural Contaminants From Soil Water Through The Epikarstic Zone, Brian Ham

Masters Theses & Specialist Projects

Agriculture contamination is very common in karst systems due to the vulnerability of these aquifers. Animal waste is often spread across crop land to enrich the soil with nitrates and phosphates. Herbicides and pesticides are also applied to the crops. The transport of these pollutants through the soil and epikarst is a difficult process to monitor due to the complex, heterogeneous behavior of the groundwater as it makes its way down to the aquifer below.

An experimental site at Crumps Cave lended a unique opportunity to monitor the vadose zone at a waterfall in the cave below. A previous dye …


"All The Crises Reached A Concerted Crescendo" - The Arab Oil Embargo And Why The United States Was Unprepared For It, Jonathan D. Chilcote Dec 2009

"All The Crises Reached A Concerted Crescendo" - The Arab Oil Embargo And Why The United States Was Unprepared For It, Jonathan D. Chilcote

Masters Theses & Specialist Projects

During the 2008 spike in oil prices, oil companies and government officials were brought under close scrutiny as many Americans began to question why prices were able to rise so quickly. Americans had become accustomed to living in an economy where cheap oil was the norm, and demanded answers when that situation changed. What most of them did not know is that they were repeating history and mimicking the response to the 1973 oil embargo. Just as in 2008, the United States faced a crisis in 1973 with which it was unprepared to effectively cope. This thesis analyzes the reasons …


Analysis Of Mammoth Cave Pre-Park Communities, Matthew Brunt Dec 2009

Analysis Of Mammoth Cave Pre-Park Communities, Matthew Brunt

Masters Theses & Specialist Projects

Before the creation of Mammoth Cave National Park, this area was home to numerous communities, each with a sense of identity. To prepare for the creation of the National Park, all residents living within these communities were relocated, and many of these communities were lost to the passage of time. Today, public memory of these lost communities is being fostered by the descendents of the pre-park area.

Through the use of a Historical Geographic Information System, 1920 Edmonson County manuscript census data, and statistical analysis, the demographic composition of these lost communities was explored. This project not only brought to …

Green Employees: Organizational Identification In An Environmentally Friendly Company, Jenna Haugen Aug 2009

Green Employees: Organizational Identification In An Environmentally Friendly Company, Jenna Haugen

Masters Theses & Specialist Projects

Environmental sustainability is an issue facing our global society and one that must be addressed through communication in order to encourage change amongst individuals. The current research focuses on the organization, in this instance a “Green” printing company, and its role in building identification amongst employees. This study focuses on environmental sustainable practices initiated or continued by employees through the use of a directed mission statement and organizational rhetoric. Utilizing individual interviews, the findings suggest that by building organizational identification, more environmentally-friendly practices amongst organizational members may be achieved.


Near-Surface Atmospheric Response To Simulated Changes In Land-Cover Vegetation Fraction, And Soil Moisture Over Western Kentucky, Ronnie Leeper Aug 2009

Near-Surface Atmospheric Response To Simulated Changes In Land-Cover Vegetation Fraction, And Soil Moisture Over Western Kentucky, Ronnie Leeper

Masters Theses & Specialist Projects

A series of land-use-land-cover-change (LULCC) based sensitivity experiments, including changes in vegetation type, fractional vegetation (FV), and soil moisture (SM), over Western Kentucky were conducted to investigate atmospheric response to land-use. The choice of land-use for this study was chosen in the context of Western Kentucky’s historical LULCC. For this study, vegetation types considered were grassland, forest, and bare soil with further variations in FV for grassland and forest at 25, 50, 75, and 100 % and systematic increases and decreases in volumetric SM of 0.05, 0.10, and 0.15 m3 m-3. To the author’s knowledge, this is the first assessment …


A Survey Of Drought Impacts And Mitigation Planning In Kentucky, Crystal Jane Bergman Aug 2009

A Survey Of Drought Impacts And Mitigation Planning In Kentucky, Crystal Jane Bergman

Masters Theses & Specialist Projects

Drought is a well-known and costly climate-related natural hazard. Unlike other climate-related natural hazards, droughts are usually long in duration and may cover a large region, the physical boundaries of areas affected by drought are sometimes arbitrary, and the impacts are sometimes difficult to identify. Climate records since 1895 show that drought has occurred periodically in Kentucky. The drought of 2007 was the most recent drought to affect Kentucky and is the primary focus of this research. The purpose of this research is to identify impacts of drought and potential vulnerabilities to various drought impact sectors in Kentucky so that …


The Study Of Variations In The Properties Of Biodiesel On Addition Of Antioxidants, Hiranmayee Kandala Aug 2009

The Study Of Variations In The Properties Of Biodiesel On Addition Of Antioxidants, Hiranmayee Kandala

Masters Theses & Specialist Projects

This research studies variations in biodiesel upon addition of different concentrations of antioxidant and petrodiesel additives. Oxidation onset temperature, oxidation induction time, oxidative stability, thermal stability, crystallization onset temperature and moisture retention properties of the biodiesel, with and without antioxidants have been studied. Antioxidants like BHT, BHA, PrG, Vit E and Vit C were added to the biodiesel during the study. These samples were analyzed using the PDSC, TGA, DSC and TGA-SA instrumentation.

The results of this research show an improvement in the OOT, OIT and Oxidative stability of biodiesel with the addition of antioxidants and by blending the biodiesel …


Assessing Organic Matter Breakdown And Associated Macroinvertebrate Community Structure In Headwater Streams: Effects Of Hydrologic Gradients And Upland Timber Harvesting, Miller Scott Jarrell Jul 2009

Assessing Organic Matter Breakdown And Associated Macroinvertebrate Community Structure In Headwater Streams: Effects Of Hydrologic Gradients And Upland Timber Harvesting, Miller Scott Jarrell

Masters Theses & Specialist Projects

I examined the effects of hydrologic gradients and upland timber harvesting with different streamside management zone widths on yellow-poplar (Liriodendron tulipifera) processing and the associated macroinvertebrate community structure in the Cumberland Plateau ecophysic region, U.S.A. Prior to upland timber harvesting, 5.0 ± 0.1 g yellow-poplar leaf packs were constructed, zip-tied to gutter nails, and placed into 7 perennial and 6 temporary stream reaches with similar physiochemical and geomorphic characteristics. From December 2007 to May 2008, 3–5 leaf packs were collected per reach monthly. I found significant differences in the functional feeding group composition. Temporary reaches contained higher shredder, gathering-collector, predator, …


Modeling Stormwater Pollutant Transport In A Karst Region--Bowling Green, Kentucky, Allison H. Ross Jul 2009

Modeling Stormwater Pollutant Transport In A Karst Region--Bowling Green, Kentucky, Allison H. Ross

Masters Theses & Specialist Projects

The management of stormwater runoff is a particular challenge for communities in karst regions. Most guidelines for compliance with regulations for stormwater monitoring and mapping pertain to non-karst environments. It can be argued that effective stormwater management is even more essential to karst regions because stormwater receives little or no natural filtration as it is transferred through conduits in the subsurface and the buildup of pollutants underneath can be detrimental to community and environmental health if not effectively mitigated. Because of the limited resources available to determine how stormwater runoff carries potential pollutants across the surface before being transferred to …
