Mosquito Hunter: An Intern's Perspective In A Public Health Department Mosquito Surveillance Program, Marisa Walterbusch
Mosquito Hunter: An Intern's Perspective In A Public Health Department Mosquito Surveillance Program, Marisa Walterbusch
The University Honors Program
As a Special Services Intern at Public Health - Dayton & Montgomery County (PHDMC), I gained first-hand experience as to the daily functioning of a Public Health Department and had the opportunity to work on a special project, the Mosquito Surveillance Program. PHDMC employs professionals in a variety of disciplines, all working towards the goal of protecting the health of the public. One way they accomplish this is through various inspections including restaurant, wellhead, and landfill. Another method to protect the public health is through the capture and testing of mosquitoes, with the goal of preventing the spread of mosquito-borne …
Degradation Of Select Chlorinated Hydrocarbons By (I) Sulfide-Treated Hydrous Ferric Oxide (Hfo) And (Ii) Hydroxyl Radicals Produced In The Dark By Oxygenation Of Sodium Dithionite-Reduced Hfo, Dhurba Raj Pandey
Browse all Theses and Dissertations
A previous work demonstrated that sulfide-treated iron oxides (goethite, hematite, and magnetite) may not show reductive pathways with carbon tetrachloride (CT) as observed with lab-precipitated iron sulfide. We examined the kinetics and products of reaction of sulfide-treated hydrous ferric oxide (HFO) towards select chlorinated hydrocarbons in batch reactors with HFO: HS- molar ratio of 1:1.5 at pH 7. CT, 1,1,2-trichlroethane (1,1,2-TeCA), 1,1,1,2-tetrachloroethane (1,1,1,2-TeCA) and 1,1,2,2-tetrachloroethane (1,1,2,2-TeCA) showed faster kinetics whereas chloroform (CF) showed slower kinetics. Trichloroethene (TCE) degradation was observed at three pHs: 7, 8 and 10; the loss in the reactors were not much different from controls at pH …
Interpretation Of A Seismic Reflection Survey And Geophysical Well Logs In Jay County, Indiana: Orientation And Composition Of A Carbonate Layer Below The Mount Simon Sandstone, Md Saiful Alam
Browse all Theses and Dissertations
In August 2017, a dynamite-sourced 2D seismic reflection survey was conducted along a gravel road northwest of Portland, Indiana. The main focus of the survey was to determine the orientation of a lithologic unit previously identified by Welder (2014) on a similar 2D seismic reflection survey in the same area. Drillers logs of two wells within this area identified a limestone layer below the Mt. Simon Sandstone, and a similar limestone layer was identified in a well drilled in Clark County, Ohio. As the focus of this study, this limestone layer will be informally named the `Votaw limestone'. The seismic …

Power Scaling Of The Mainland Shoreline Of The Contiguous United States, Erik S. Vasko

Previous fractal analyses of shoreline roughness have measured the fractal dimension of long segments of shoreline, e.g. Mandelbrot (1983) quantified the shoreline of the west coast of Britain and Feder (1988) quantified the shoreline of Norway. Consequently, changes in roughness along short segments are not captured by the analysis. In this study, the fractal dimension of the mainland shoreline of the contiguous United States has been measured in 125, 250, and 375 km segments using the box-counting method. The box counting method is based on the equation N = c x b where N is number of occupied boxes, C …
Evaluating Sediments As An Ecosystem Service In Western Lake Erie Through Quantification Of Nitrogen Cycling Pathways, Ashlynn Rose Boedecker
Evaluating Sediments As An Ecosystem Service In Western Lake Erie Through Quantification Of Nitrogen Cycling Pathways, Ashlynn Rose Boedecker
Browse all Theses and Dissertations
Lake Erie experiences annual cyanobacterial harmful algal blooms (HABs), comprised mostly of non-nitrogen-fixing Microcystis, due to excess nitrogen (N) and phosphorus (P) inputs (eutrophication). Lake Erie's watershed is mostly agricultural, and fertilizers, manure, and drainage practices contribute to high nutrient loads. This study aimed to clarify the role of Lake Erie sediments in either exacerbating or mitigating conditions that fuel HABs via recycling and/or removal, respectively, of excess N and P. Sediment-water interface N dynamics were evaluated in low HAB (2016, dry) and high HAB (2017, wet spring and early summer) years. Intact sediment cores and overlying water were collected …
Lead In Tap Water From The City Of Dayton, Ohio, Kayla Marie Haman
Lead In Tap Water From The City Of Dayton, Ohio, Kayla Marie Haman
Browse all Theses and Dissertations
Lead (Pb) in public tap water is a national health concern and is the main pathway of human exposure to Pb. The City of Dayton has verified Pb pipelines and homes with Pb plumbing; thus, residents are at risk to Pb leaching into their tap water. I sampled water from 130 residential and 24 public water taps and measured Pb and copper (Cu). Five percent of samples exceeded the action level for Pb (> 15 [micro]g/L) and none exceeded the action level for Cu. The City of Dayton's lead pipeline map identifies potential Pb exposure from Pb distribution pipes. However, …
Geophysical Exploration Of The Upper Crust Underlying North-Central Indiana: New Insight Into The Eastern Granite-Rhyolite Province, Michael Ray Green
Geophysical Exploration Of The Upper Crust Underlying North-Central Indiana: New Insight Into The Eastern Granite-Rhyolite Province, Michael Ray Green

This study analyzes ten 2D seismic lines donated by CountryMark together with potential field data to examine the upper crustal structure near Wabash, Indiana. These seismic profiles reveal significant relief of the Precambrian Unconformity and prominent upper crustal reflections. The Precambrian Unconformity interpreted from the unmigrated stacked seismic sections is characterized by undulations and bowtie artifacts. Zero offset seismic models constructed using profiles of the exposed Precambrian Unconformity across the Eastern Granite-Rhyolite Province outcrops of the St. Francois Mountains feature the same seismic expression. The upper crust below the Precambrian Unconformity on the Countrymark seismic sections is also characterized by …
Sedimentary Architecture And Paleochannel Dimensions Of The Lamotte Sandstone Of Southeastern Missouri, Jamilyn Ann Moore
Sedimentary Architecture And Paleochannel Dimensions Of The Lamotte Sandstone Of Southeastern Missouri, Jamilyn Ann Moore
Browse all Theses and Dissertations
This study focused on outcrops of the Lamotte Sandstone (Cambrian) within Hawn State Park near Farmington, Missouri. The goal was to estimate the channel depth, channel width, and channel belt width for rivers that deposited this portion of the Lamotte Ss. Sedimentary characteristics (grain size, bedding type and thickness, and unit bar and compound bar boundaries) were mapped within three outcrops on photomosaics and within graphic sedimentary logs (totaling 14 m vertically). The change in sedimentary characteristics from the lowest to the highest deposits studied suggest the formation and filling of a major channel within the braided channel belt. The …
