Ohio Recovery Housing: Resident Risk And Outcomes Assessment, Elyjiah Potter, Bivin Sadler

SMU Data Science Review

Addiction and substance abuse disorder is a significant problem in the United States. Over the past two decades, the United States has faced a boom in substance abuse, which has resulted in an increase in death and disruption of families across the nation. The State of Ohio has been particularly hard hit by the crisis, with overdose rates nearly doubling the national average. Established in the mid 1970’s Sober Living Housing is an alcohol and substance use recovery model emphasizing personal responsibility, sober living, and community support. This model has been adopted by the Ohio Recovery Housing organization, which seeks …

Reservoir Characterization Of The Utica Shale Play Using Well Log Data In Columbiana, Ohio, Tyler L. West

Electronic Theses and Dissertations

The Ordovician Utica shale play is rapidly developing throughout the Appalachian Basin. The play is a mixed carbonate-siliciclastic system that grades from primarily carbonates at its base in the Lexington/Trenton limestones into primarily shale within the Utica shale. As of January 2021, it is the third highest-producing dry shale gas play in the contiguous U.S., although it is known to produce wet gas and oil in various parts of the basin. In addition to being an unconventional reservoir, the Utica shale, an informal unit in Ohio where the main fairway is located, is a known source rock for much of …

European Starling Use Of Nest Boxes Relative To Human Disturbance, Bradley Blackwell, Bruce N. Buckingham, Morgan B. Pfeiffer

USDA Wildlife Services: Staff Publications

gars and to engine and flight surfaces of moored aircraft. We questioned whether consistent removal of nest material would negatively affect use of a nest site, measured by a reduction in material accumulation. We conducted our study on a 2,200-ha site in Erie County, Ohio, USA (41° 22’ N, 82° 41’ W), from April 15 through June 2, 2020. We used 120 wooden nest boxes on utility poles, protected by an aluminum predator guard below the box. Our treatments included (1) twice weekly, repeated nest material removal (RMR; n = 40 nest boxes); (2) complete nest removal, but only after …

Unearthing The Effects Of European-American Settlement On A Northeast Ohio Kettle Lake Through Diatom Stratigraphy, Justine Paul A. Berina

Senior Independent Study Theses

Recently, wetland conservation has highlighted the necessity for assessing limnological changes following European-American settlement. A prior study at Brown's Lake (northeast Ohio) identified a stratigraphic sequence that shows an abrupt transition from organic-rich muds to several centimeters of a bright loess layer, then a recovery to organic-rich sediments near the top. Based on ²¹⁰Pb dates, the loess deposition occurred before 1846 CE, when a growing population cleared trees and farmed intensively. Likewise, organics had recovered after 1950 CE, when people abandoned farmland and practiced conservation tillage. However, the effects of settlement on limnology are poorly known. Diatoms (microscopic algae; …

Geochemical Characterization Of The Utica Shale Play Using Xrf-Based Chemostratigraphy In Ohio, Barbara Kemeh, Julie M. Bloxson

Electronic Theses and Dissertations

The Utica shale is an extensive gas shale play within the Appalachian Basin, expanding from Quebec through New York, into Pennsylvania, West Virginia and Ohio. Currently a target for gas exploration, it is also the source rock for much of the Paleozoic reservoirs throughout the basin. However, the Utica-Point Pleasant lithology varies significantly across the Appalachian Basin which can make it challenging to characterize.

The Utica shale Play consists of the Trenton/Lexington Limestones, Point Pleasant Formation and Utica shale. The Point Pleasant Formation and Utica shale are often grouped together, especially in Ohio because they are difficult to visually distinguish …

Statistical Analysis Of Land Cover Conversion Trends In Northwest Ohio, Chaska Mcgowan

Honors Projects

Agricultural land in the U.S. is abundant but not infinite. Change in cropland impacts national and local economies and the natural environment. The Black Swamp Conservancy (BSC), a non-profit land trust in Perrysburg, Ohio, is committed to preserving agricultural and natural lands in the Northwest Ohio region for future generations. This project was designed in collaboration with the BSC to illustrate the spatial distribution of land cover change within their sixteen-county service area in Northwest Ohio and to find a list of factors associated with land cover change in the region. The primary data source was the National Land Cover …

Effects Of Bridge Sites On Freshwater Mussel Community Structure And Density, Holly Rundle

Undergraduate Honors Thesis Projects

Freshwater Mussels (family Unionidae) are one of the most imperiled group of species found in the United States. Construction activities, such as bridges, can affect sedimentation rates and local deposition, as well as the hydrologic flow of the stream. Since mussels are protected in Ohio, surveys must be done prior to bridge construction to determine the impact of the project on mussel resources. Our study used data from survey reports conducted in Ohio from 2013-2019 at bridge sites. We organized the data to determine mussel community structure and density directly underneath bridges compared to away from bridges. We found the …

Optimization Study Of A Combined Wind-Solar Farm For A Specified Demand, Venkat Siddhartha Rama

Browse all Theses and Dissertations

At the present time, using wind and solar energy for producing electricity in the United States is becoming cost competitive. According to Lazard’s 2019 [36] levelized cost of energy (LCOE) analysis of a number of energy sources used for producing electricity in the United States, wind and solar are cheaper than natural gas and coal. While capital, maintenance, operation, and fuel costs are included in LCOE numbers, energy source intermittency is not. Intermittency is an important issue with wind and solar energy sources, but not with natural gas or coal energy sources. Combining wind and solar energy sources into one …

Unconventional Oil And Gas Extraction In Ohio: Regulations, Production And Water Quality, Brittany Garman

Electronic Theses and Dissertations

The Utica shale play is the main target for unconventional oil and gas extraction in Ohio. Over 2,000 wells have been drilled since the first in 2011. This rapid expansion has led to concerns over the availability of information and potential environmental impacts. An assessment of readily available data was done through an examination of the ODNR website for oil and gas regulations, permits, spud and completion reports, water usage and waste data, and complaints, as well as brine and de-icer application. Water quality testing of an exceptional warm water tributary in the Captina Creek watershed in Belmont County, Ohio …

Lead In Tap Water Of Public Schools Near Dayton, Ohio, Baylee Stark

Browse all Theses and Dissertations

Lead (Pb) is a human-health concern, especially with regard to exposures of children. Lead contaminated drinking water is a primary route of exposure for children; however, water sampling for Pb is voluntary in schools with a public water supply. This study examined Pb in tap water from public schools around Dayton, OH. Schools were selected to span a range of ages (construction year) and community socioeconomic status. Of the 28 schools contacted, seven responded "affirmatively" to sampling, two responded "negatively", and 19 did not respond. None of the schools that were sampled had Pb concentrations exceeding the U.S. EPA guidelines …

Experiences In Northern Bobwhite Propagation And Translocation In Ohio, 1978-2012, Mark J. Wiley, Nathan J. Stricker

National Quail Symposium Proceedings

Ohio once boasted a population of 7 million northern bobwhites (Colinus virginianus). Catastrophic blizzards during 1976–1977 and 1977–1978 brought winter quail mortalities of 85% and 80%, respectively. Ohio’s bobwhite population was 430,000 in 1978, a 90% reduction from 1976. Remnant quail populations were small, isolated, and incapable of rapid recovery. The Ohio Department of Natural Resources (ODNR) initiated a statewide stocking effort to expedite population growth. The ODNR chose to propagate wild quail in captivity and release first-generation progeny (F1). Throughout 1980–1986, the ODNR released 65,000 F1 quail statewide. The ODNR monitored population response with North American Breeding …

Temporal And Spatial Assessment Of Usable Space And Cover Type Interspersion For Northern Bobwhites On Private Farmlands In Southwestern Ohio, Robert J. Gates, Mark J. Wiley, Adam K. Janke, Marjorie R. Liberati

National Quail Symposium Proceedings

Contemporary landscape change driven by socio-economic forces and advances in agricultural technology do not favor northern bobwhites (Colinus virginianus) in the Midwestern United States. The challenge of bobwhite conservation is to provide sufficient quantities of habitat with optimal configurations in proportions that satisfy needs throughout the year on private-owned working lands. We radio-tracked 58 coveys and 98 individual birds throughout the year in 2009-10 and 2010-11 on privately owned farmland in southwestern Ohio. We investigated temporal changes in usable space from use-availability data. Estimated proportions of usable space based on analyses of habitat selection across four study sites …

Full-Waveform Inversion With Scaled-Sobolev Preconditioning Applied To Vibroseis Field Data, Benjamin Paul Consolvo

Electronic Thesis and Dissertation Repository

I present an application of a high-resolution subsurface imaging technique known as “full-waveform inversion” (FWI) to a vibroseis seismic dataset from eastern Ohio, USA. The data were collected over a crooked line with rough topography, 3.5 km maximum offsets, and no significant frequency content below 12 Hz. These parameters present challenges to obtaining quality images from FWI. The use of a preconditioner–the ‘scaled-Sobolev preconditioner’ (SSP - Zuberi and Pratt, 2017)–on the gradient of the misfit functional was key to obtaining low wavenumbers without discarding high wavenumbers. The results represent the first successful application of FWI with the SSP to a …

Methylmercury Bioaccumulation In Spotted Salamanders (Ambystoma Maculatum) In Southern Ohio, Rachel Alex Walker

Browse all Theses and Dissertations

Mercury (Hg) is a volatile element increasing in concentration in the environment as a result of anthropogenic emissions. Microorganisms can transform mercury into monomethylmercury (MMHg), the form of Hg that bioaccumulates, biomagnifies, and can harm humans and wildlife. Most studies of MMHg bioaccumulation in wildlife have focused on aquatic organisms due to consumption of fish being the primary route of human exposure to MMHg. However, organisms in terrestrial ecosystems also are exposed to MMHg that may impact ecosystem biodiversity, food-web dynamics, and organisms and ecosystem health. I investigated bioaccumulation and maternal transfer of MMHg in spotted salamanders (Ambystoma maculatum) captured …

Rubber Roads For The Rubber City: Testing The Suitability Of Rubberized Asphalt For Roads In Northeast Ohio, Jessica M. Fraser

Williams Honors College, Honors Research Projects

This research paper explores the benefits of using rubberized asphalt concrete (RAC) versus normal asphalt concrete (NAC) and why it is environmentally important. New road construction and repair of roadways due to potholes are always occurring in Northeast Ohio. Recently, the city of Akron’s transportation budget has increased, which includes projects such as reconstructing asphalt and resurfacing pavements throughout the city of Akron. Using rubberized asphalt may improve the quality of our roads and reduce roadway degradation which will likely save cities money.

Using rubberized asphalt recycles old tires, which do not decompose, and creates a positive use for them …

Apparent Glacially Induced Structural Controls On Limestone Conduit Development In Ohio Caverns, United States, Adrienne M. Watts, Ira D. Sasowsky

International Journal of Speleology

Rock discontinuities such as bedding planes and joints are important controls on the form that caves take. We examined structural controls on the development of Ohio Caverns. The cave formed in Devonian limestone underlying a small bedrock knob (Mt. Tabor) within the Interior Lowland province, United States. The area has been overridden by continental glaciation multiple times. The bedrock is pervasively fractured, with many curved and wavy near-vertical fractures showing many different orientations. In the case of Ohio Caverns, it appears that the controlling fractures in map view may not be joints sensu stricto, but rather some combination of …
