This study assessed the frequency, distribution, and survival of uterine corpus malignancies in KY, and specifically the differences between Appalachia (AP) and non-Appalachia (NAP). This study utilizes SEER and Kentucky Cancer Registries to study uterine corpus malignancy between January 1, 2000 and December 31, 2014. The analysis looks at incidence between diagnoses...

Removal of Chloroform from Drinking Water

John S. Zogorski, George D. Allgeier & Robert Lee Mullins
Abstract: The overall objective of this investigation was to evaluate via laboratory experiments the technical feasibility of reducing trihalomethane levels in drinking water. Special attention was directed at the removal of chloroform since: (a) it is the only trihalomethane which has been shown to be carcinogenic in animal tests; and (b) this compound generally comprises the largest fraction of the total trihalomethane content of chlorinated waters in Kentucky. Trihalomethanes are present in municipal drinking waters...

Generalized Geologic Map for Land-Use Planning: Green County, Kentucky

Daniel I. Carey & Adam Pike
Abstract: This map is not intended to be used for selecting individual sites. Its purpose is to inform land-use planners, government officials, and the public in a general way about geologic bedrock conditions that affect the selection of sites for various purposes. The properties of thick soils may supercede those of the underlying bedrock and should be considered on a site-to-site basis. At any site, it is important to understand the characteristics of both the...

The Economic Value of Natural Areas for Recreational Hunting

Kenneth Gene Holbrook
Abstract: The pressures of population growth, urbanization, and improved transportation are diminishing the availability of quality naturalistic sites for recreation while at the same time producing greater demands for their use. One cause contributing to the reduction in acreage in naturalistic areas is the construction of reservoirs. The recreational hunting value of the naturalistic area to be inundated should be considered as a negative consequence in the economic evaluation of a proposed reservoir site. This...

This study was conducted in 2015 and 2017 and plots were maintained vegetatively with two to four week mowing. Morning and afternoon sample...

Effects of Stream Channel Improvements on Downstream Floods

Yang H. Huang & Ronald K. Gaynor
Abstract: This report presents a self-calibrating watershed model for predicting the effect of channel improvements on downstream floods. The model is called MOPSET because it is a modified version of OPSET developed several years ago at the University of Kentucky. OPSET is a computerized procedure for determining an optimum set of parameter values by matching synthesized flows with recorded flows. Major modifications include the replacement of the modified Muskingum method of channel routing by a...

Algal Growth and Decomposition: Effects on Water Quality, Phase II

Edward G. Foree & Ronald L. Barrow
Abstract: The decomposition and associated nutrient regeneration of three unialgal cultures and one mixed culture containing an indigenous population of bacteria and microscopic animals were studied under dark, constant temperature laboratory conditions. After periods of nutrient-deficient growth ranging from O to 30 days, these cultures were inoculated with decomposer populations and subjected to anaerobic and aerobic environments for the decomposition studies. The extend of decomposition was determined from the percentage volatile suspended solids and percentage...

Late Pleistocene Adaptations in the Midsouth: The Paleoindian Occupation of the Carson-Conn-Short Side and the Lower Tennessee River Valley

James Scott Jones
Abstract: The Midsouth has long been known to be a locus of Paleoindian (13,200-10,000 yrs B.P.) populations. Paleoindian populations have generally been characterized as highly mobile hunter-gatherers with egalitarian social structure. Utilizing the theoretical lens of diversification and intensification of resource use, the Late Pleistocene adaptations of the region’s populations are examined from both a large scale or coarse grain perspective as well as more fine grain data from the site level. Previous models of...

Effects of Backpack Type on Kinematics of the Lower Back During Walking and Jogging

Cazmon Suri
Abstract: Heavy backpacks have been suggested to have a pathogenic role in experience of low back pain among children. We have conducted a repeated-measure study to investigate the backpack-induced changes in lumbo-pelvic coordination of forty gender-balanced college age students when they walked and jogged on a treadmill with two different types of backpacks: normal and ergonomically modified. The backpack-induced changes in lumbo-pelvic coordination were larger when carrying an ergonomically modified vs. a normal backpack as...

Electronic and Optical Properties of Metastable Epitaxial Thin Films of Layered Iridates

Maryam Souri
Abstract: The layered iridates such as Sr2IrO4 and Sr3Ir2O7, have attracted substantial attention due to their novel electronic states originating from strong spin-orbit coupling and electron-correlation. Recent studies have revealed the possibilities of novel phases such as topological insulators, Weyl semimetals, and even a potential high-Tc superconducting state with a d-wave gap. However, there are still controversial issues regarding the fundamental electronic structure of these systems: the origin of the insulating gap is disputed as...

Cocaine Choice: A Novel Procedure for Investigating Neuronal Activation Mediating Cocaine Preference

Jonathan Jenn-Sheng Chow
Abstract: Cocaine use disorder is a significant health problem, negatively impacting individuals afflicted. While preclinical self-administration research has provided invaluable insight into the neurobehavioral mechanisms that underlie cocaine abuse, cocaine use outside of the laboratory occurs within an environment where other goods are also available ubiquitously. Although there is an ever-increasing literature investigating drug vs. non-drug choice in rodent models and how alternative goods can compete with the subjective value of cocaine, the neurobiological mechanisms...

Causal Attributions and Smoking Behaviors in Cervical Cancer Survivors: A Mixed-Methods Pilot Study

Gabriella E. Puleo
Abstract: This cross-sectional, mixed-methods study examined the nature of, and association between, causal attributions and current smoking behavior in cervical cancer survivors who were smokers at cancer diagnosis (n=50). As a whole, participants’ beliefs about smoking as a risk factor or cause of cervical cancer in general (i.e., global attribution) and/or their own cervical cancer (i.e., personal attribution) reflected far greater endorsement of global than personal attributions. Data collection involved a quantitative survey and an...

The Influence of Life Domains on Adolescent and Adult Offending: Testing an Extension of Agnew's General Theory

Joseph Mark Calvert
Abstract: More than a decade has passed since Agnew (2005) introduced his General Theory of Crime and Delinquency (GTCD). Despite this interval, GTCD remains a relatively untested theory. Drawing on previous testing efforts, the current research provides a systematic assessment of Agnew's theoretical propositions. It also provides only the second empirical examination of Cochran's (2015) extension of GTCD, which incorporates religion as a sixth distinct life domain. Nested negative binomial regression modeling and Poisson regression...

Digital Computer Modeling of Limestone Groundwater Systems

John Thrailkill & David P. Beiter
Abstract: Because limestone groundwater flows mainly In discrete openings, limestone aquifers are fundamentally different from aquifers In granular rocks. A digital computer program which simulates flow in a limestone aquifer as a pipe network was written and compared with the Sinkhole Plain aquifer of west-central Kentucky. A reasonably good fit between observed parameters of the aquifer and those calculated were obtained under assumed conditions of both laminar and turbulent now In the aquifer. The Indicated...

Covariance Analysis of Reservoir Development Effects on Property Tax Base

Claude M. Vaughan, Jr.
Abstract: Much attention has been given in recent years to the development of water resources in the United States. Large scale multi-purpose dam and reservoir projects are of particular interest. Such projects are traditionally undertaken after the resulting benefit has been found to exceed the required cost. The benefits which are most readily evaluated are primary benefits such as flood control, hydroelectric power, and navigation. The purpose of this study is to investigate secondary benefits...

Flexible Liminality Among the Tibetan Diaspora: Tibetan Exiles Adjusting Cultural Practices in Dharamsala, India and the United States

Sneha Thapa
Abstract: In this dissertation, I investigate the characteristics and quality of liminality among the Tibetan exile community in Dharamsala, India, and the United States. I argue that the quality of their liminality defines this exile community’s ability to maneuver and voice their influence to geo-political community of states that surround them, all while within their liminal condition. The Tibetan exile people live as stateless foreigners in India but have a better standard of living and...
