Anita L. Morse & Edward Zeigler
Abstract: This report is intended to set forth some of the problems and solutions involved in financing and regulating water quality control. The purpose is to record some of the major problems confronting those who legislate water quality, those who espouse technological answers, and those who see the problem in terms of economic solutions. The limits placed by political and institutional constraints on solutions to these problems are frequently not understandable. Within this report are...

A Brain-Computer Interface for Closed-Loop Sensory Stimulation During Motor Training in Patients with Tetraplegia

Sarah Helen Thomas
Abstract: Normal movement execution requires proper coupling of motor and sensory activation. An increasing body of literature supports the idea that incorporation of sensory stimulation into motor rehabilitation practices increases its effectiveness. Paired associative stimulation (PAS) studies, in which afferent and efferent pathways are activated in tandem, have brought attention to the importance of well-timed stimulation rather than non-associative (i.e., open-loop) activation. In patients with tetraplegia resulting from spinal cord injury (SCI), varying degrees of...

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...

Analysis of Unsteady Flow Toward Artesian Wells by Three-Dimensional Finite Elements

Yang H. Huang & Shen-Jyh Wu
Abstract: A three-dimensional finite element computer program was developed for analyzing unsteady flow toward artesian wells. The program is designed especially for determining the drawdown around an artesian well penetrating fully or partially a nonhomogeneous and anisotropic aquifer of irregular shape and cross section. It can also be used as a general program for aquifer simulation and evaluation. A major advantage of the program lies in the minimum amount of input data required. By assuming...

Determination of Trace Elements in Water Utilizaing Atomic Absorption Spectroscopy Measurement

Gary D. Christian, J. Preston, III Miles, Ronald Sensmeier, Melvin Sensmeier, Loraine Craig, Lynn Phibrick & Sudarshan Lal
Abstract: A variety of flameless atomic absorption methods have been investigated for the possible determination of trace elements in water. The general applicability of each technique was determined and where applicable, procedures have been developed for the determination of trace elements in natural waters. Metals were preconcentrated by electrodeposition on a wire. The metals were then atomized for atomic absorption measurement by resistive heating of the wire. As little as 0.01 part per million (ppm)...

To develop a material specification and application criteria for...


Nour Al Haj Baddar
Salamanders have an extraordinary ability to regenerate appendages after loss or amputation, irrespective of age. My dissertation research explored the possibility that regenerative ability is associated with the evolution of novel, salamander-specific genes. I utilized transcriptional and genomic databases for the axolotl to discover previously unidentified genes, to the exclusion of other vertebrate taxa. Among the genes identified were multiple mmps (Matrix metalloproteases) and a jnk1/mapk8 (c-jun-N-terminal kinase) paralog. MMPs function in extracellular matrix remodeling...

Major Lower Paleozoic Horizons of the Southern Illinois Basin

John B. Hickman
The geology exposed at the surface in the southern Illinois Basin has been mapped in great detail by countless workers over the past century. With the exception of limited and scattered exposures in incised river valleys, the oldest rocks exposed outside of the Jessamine, Nashville, and Ozark Domes surrounding the Illinois Basin are Mississippian in age. Extensive deposits of Cambrian–Devonian sediments occur in the subsurface above crystalline basement in this region, however. All available data...

The purpose of this study was to examine principal behaviors, identified by teachers and principals, which foster collective efficacy among teachers. As instructional leaders of a school, principals are expected to lead their schools. Behaviors exhibited by the principal can either help or hinder the success of the school and teachers and students in that school. This study will assist principals, aspiring principals, and instructors of principal preparation programs in knowing what behaviors are necessary...

Beyond Telling

Jane Samuel
Despite calls for increased Adoption Communication Openness (ACO) within the adoptive family, research indicates that families still struggle to accomplish the recommended elements and levels of openness. What could be holding families back from this key process? Three focus groups comprised of 17 adoptive parents of early adolescents (aged 10-14) who were age 0-2 at the time of placement were thematically coded. This inductive analysis revealed the complexity rooted in being —sometimes successfully and sometimes...


Michael Dalessio
A multitude of higher education institutions have adopted comprehensive smoke- and tobacco-free policies to minimize tobacco use, increase quit attempts, and reduce exposure to secondhand smoke on campus. However, the majority of campuses across the U.S. still have non-comprehensive policies and/or designated tobacco use areas. Given the limited research in this area, the purpose of this dissertation was to assess the attitudes, perceptions, tobacco use behaviors, and actual observational compliance of students, faculty, and staff...


Morgan Black
The forested environments of the subalpine and upper montane zones of the eastern Sierra Nevada mountains (California) are biodiverse and valuable ecosystems that are sensitive to hydroclimate changes. The history of high-altitude vegetation changes in the eastern Sierra Nevada is underexplored, and this knowledge gap can be addressed using a paleolimnological approach. In this study, we use a long (~9.5 m) sediment core from Convict Lake, a glacial lake situated in the upper montane zone...

Online Language Acquisition and Leadership in Higher Education-Governed Intensive English Programs

Brandon Decker
Research has indicated accredited, U.S. higher education-governed intensive English programs (IEPs) often struggle financially due to a scarcity of resources (namely students) because of political and global economic factors and increased competition (ICEF Monitor, 2017; IIE, 2017; Ladika, 2018; Soppelsa, 2015). However, few IEPs advertise online language acquisition (OLA) courses despite the increase in online study methods at the higher education institutes governing the programs and its use by competitors. The purpose of this study...

Horseweed (Conyza canadensis (L.) Cronq.) is prevalent in Kentucky and can be difficult to control. Research has shown multiple weed control methods to be more sustainable than relying on chemical control alone, so the use of multiple methods for horseweed management was examined in this study. The main objective was to determine best practice(s) to reduce horseweed prior to soybean [Glycine max (L.) Merr.]. Treatments included: fall-planted cover crop [CC; cereal rye (Secale cereale L.)...

An Inverse Eigenvalue Problem for the Schrödinger Equation on the Unit Ball of R3

Maryam Ali Al Ghafli
The inverse eigenvalue problem for a given operator is to determine the coefficients by using knowledge of its eigenfunctions and eigenvalues. These are determined by the behavior of the solutions on the domain boundaries. In our problem, the Schrödinger operator acting on functions defined on the unit ball of $\mathbb{R}^3$ has a radial potential taken from $L^2_{\mathbb{R}}[0,1].$ Hence the set of the eigenvalues of this problem is the union of the eigenvalues of infinitely many...

As required by Kentucky Revised Statutes 189.635, “every law enforcement agency whose officers investigate a vehicle accident of which a report must be made...shall file a report of the accident...within ten days after investigation of the accident upon forms supplied by the bureau.” The stated purpose of this requirement is to utilize data on traffic...

Critical Path for Project Development

Steven Douglas Kreis, Bryan Gibson, Jeff Jasper, Christopher W. Van Dyke, Candice Y. Wallace, Rachel Catchings & Sarah M. McCormack
Overseeing the delivery of highway projects at the Kentucky Transportation Cabinet (KYTC) requires the successful coordination of activities and inputs from multiple external agencies and members of the agency’s Project Development team, who have varied disciplinary backgrounds. Despite the complexity of project delivery, the Cabinet presently does not estimate hours and project milestone dates until after it has selected a design consultant. Moving forward KYTC should explore requiring consultants to develop a critical path method...

Investigating the Use of In-Place Lateral Pull Off Tests to Determine the Compressive Strength of Structural Concrete

Charlie Sun
The Kentucky Transportation Cabinet’s current practice for determining the compressive strength of structural concrete consists of two methods. Both methods require that samples be delivered to an off-site facility for testing. Accordingly, affected parties on the project site must wait for the delivery of samples to the off-site facility, the performance of tests and analysis of test data, and the return of test results to the project site. Analysis of existing structural concrete requires core...


Catherine Nunn Lawless
Research shows that public school districts that follow traditional means of instruction and assessment are insufficiently preparing students for success in the today’s global world. As a result, students are entering into higher education institutions and the workforce without the necessary skills to succeed in these 21st century environments. Extant literature suggest that there is a broad consensus on this perspective in public and private sectors nationally and globally. Evidence shows that some school district...
