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

E. Glynn Beck, David A. Williams & Daniel I. Carey
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...

Bibliography of the Kentucky Geological Survey, 1839 Through 1978

Abstract: It is the hope of the authors that all of the various publications and maps of the Kentucky Geological Survey are included in this bibliography. It is our intent to revise, supplement, and update the publication lists in "Geological Research in Kentucky" by Willard Rouse Jillson (1923). During its history the Kentucky Geological Survey has suffered losses from two disastrous fires, one at Frankfort in 1929, and a second at Lexington in 1948. Many...

Remaining Resources of the Herrin Coal

Gerald A. Weisenfluh
Abstract: The Herrin coal bed (W. Ky. No. 11) is one of the most important coal resources in the Illinois Basin. To 2009, the Herrin coal had an estimated 10 million tons of production in Kentucky, and remained the second largest producer in the Western Kentucky Coal Field. The Herrin is known for its regionally extensive "blue band" rock parting, and, in Kentucky, its close association with the overlying Providence Limestone Member and Paradise coal...

Residual Next-Day Effects of Alprazolam on Psychomotor Performance and Simulated Driving in Healthy Normal Volunteers

Marion A. Coe
Abstract: The prevalence of drugged driving has increased in the United States, and some prescription medications (e.g., zolpidem) cause impairment after the predicted duration of therapeutic action has elapsed. The aim of this study is to determine if bedtime administration of alprazolam similarly impacts driving performance the following day. Volunteers were 14 healthy adults (6 males) who completed a double-blind, double-dummy within-subjects design study examining the effects of alprazolam (0.5, 1, 2mg), zolpidem (10mg), and...

Kentucky's Coal Industry: Historical Trends and Future Opportunities

Gerald A. Weisenfluh, James C. Cobb, John C. Ferm & Carol L. Ruthven
Abstract: Coal has been produced in Kentucky since the late 18th century. In the early years, all mining was by underground methods, but surface mining became the dominant method during and after World War II. In recent years, surface-mine production in both fields has decreased while underground mining has increased. In the last half of this century, the traditional steam coal market for locomotives has virtually disappeared, leaving electric power generation and coking coal for...

Evaluating Costs Associated with Management Decisions of Replacement Dairy Heifers and Their Impact on the Total Rearing Investment

Anna Hawkins
Replacement heifer rearing is critical for the future of the dairy operation, especially to improve genetic merit and maintain herd size. A replacement heifer from the day she is born to the day she calves herself is generally a 2-year investment without potential income. A myriad of options exists on how to manage, fed, and ultimately raise replacement heifers. This study quantifies the costs associated with replacement heifer management decisions from birth to calving related...

Truss Bridge Rehabilitation Prioritization

Abheetha Peiris & Issam E. Harik
Kentucky’s inventory of historic steel truss bridges is declining rapidly. There are more than 150 historic truss bridges in the Kentucky Transportation Cabinet’s (KYTC) bridge inventory. Most of these bridges require maintenance to avoid replacement. However, prioritizing the rehabilitation of these bridges based on their historic importance is challenging. While AASHTO’s Guidelines for Historic Bridge Rehabilitation and Replacement contain guidance on selecting bridges for preservation, currently there is no guidance on how to prioritize those...

US 31W Jefferson County Pavement Surface Treatment Evaluation

Tim C., Jr. Scully
Reflective cracking inevitably occurs when asphaltic concrete (AC) is placed over an existing unfractured Portland cement concrete (PCC) pavement. However, manufacturers state their products will mitigate reflective cracking, therefore extending the pavement life cycle. To evaluate the performance of each manufacturer’s product, an experimental test section consisting of a southbound and northbound segment was established on US 31W in Louisville, Kentucky. The funding for this project will help track the performance of each product from...

Language Dysfunction in Motor Neuron Disease

Natasha Garcia-Willingham
Motor neuron disease (MND) is a set of neuromuscular diseases that affect the upper and/or lower motor neurons, resulting in progressive disability. Amyotrophic lateral sclerosis (ALS) and Primary lateral sclerosis (PLS) are two forms of MND that both involve upper motor neuron degeneration, which can also accompany extra-motor changes in cognitive, behavioral, and/or emotional functioning for some individuals. Characterization of the cognitive profile of MND is still evolving, with growing interest in cognitive subtypes. The...

Impact of Seasonal Tree-Cutting Restrictions on Construction Bids

Christopher W. Van Dyke, Steven Waddle, Bryan Gibson, Sarah M. McCormack & Steven Douglas Kreis
Many of the maintenance and construction projects undertaken by the Kentucky Transportation Cabinet (KYTC) span late spring to early fall (April–October), with this period’s long days, abundant sunshine, and relatively dry conditions being ideal for performing work and minimizing delays from inclement weather. But this compressed timeline for accomplishing work introduces other challenges. Specifically, many of KYTC’s maintenance and construction activities can potentially impact summer habitat of the Indiana bat, which is listed as an...

The North American Transportation Security Center

Steven Douglas Kreis & Michael M. Barclay
There are over 800,000 hazardous materials (hazmat) shipments over the nation’s roads each day. According to the U.S. Department of Homeland Security (DHS), terrorist activity related to the transportation of hazardous materials represents a significant threat to public safety and the nation’s critical infrastructure. Specifically, the federal government has identified the government’s inability to track hazmat shipments on a real-time basis as a significant security vulnerability. In 2004, the U.S. Federal Motor Carrier Safety Administration...

Encuentro Con la Precariedad

María Julia de León Hernández
In 2008, Spain’s financial crisis had a great impact on the primary sector on which the nation’s ‘economic miracle’ was founded: housing.Land speculation, the increase in housing construction, and easy loans had become one of the hallmarks of twenty-first-century Spanish identity. The crisis del ladrillo (“brick crisis”) plunged the national economy into chaos and condemned many Spanish citizens to job insecurity, loss of earning power, threat of eviction, and put them at high risk of...

Modulation of Inflammatory Cytokine, Chemokine, and Toll-Like Genes and Transcriptome Analysis of Equine Endothelial Cells Following Infection with Equid Herpesvirus-1, and Equine Arteritis Virus.

Saranajith Wangisa Dunuwille
EHV-1 is a double-stranded DNA virus whereas EAV is a positive sense, single-stranded RNA virus. Therefore, genetically, they are very different from one another. However, both these viruses are endotheliotropic and thus, infect and replicates in equine endothelial cells resulting in vasculitis. Vasculitis is central to the pathogenesis of these two viruses. Thus, the main objective of this thesis was to investigate the inflammatory and innate immune responses of EECs that contribute towards the development...

Caregivers' Influence on Patients' Heart Failure Self-Care, Hospital Readmission and Mortality

Linda Clements
Background: Heart failure (HF) is a leading cause of hospitalization, readmissions, and death in the United States. Patients hospitalized for HF are at risk for readmission, in- hospital mortality, and early post-discharge death. In the United States, inpatient care has been estimated to cost $83,980 over the lifetime of each patient with HF. The majority of patients with HF depend on caregiver support for successful HF self-care, which is essential for optimal patient outcomes. Support...

Development of a Translational Model of Co-Use of Alcohol and Nicotine for Testing Potential Pharmacotherapies

Sarah Elizabeth Maggio
Co-users of alcohol and nicotine are the largest group of polysubstance users worldwide. Although pharmacotherapies are available for alcohol (EtOH) or tobacco use disorders individually, it may be possible to develop a single pharmacotherapy to treat heavy drinking tobacco smokers through capitalizing on the commonalities in their mechanisms of action. Towards this goal, several models of concurrent access to EtOH and nicotine were explored as potential preclinical models of co-use using female alcohol-preferring (P) rats....

Circadian Rhythm Phase Shifts Caused by Timed Exercise Vary with Chronotype in Young Adults

J. Matthew Thomas
The circadian system controls 24-hour cycles of behavior and physiology, such as rest-activity and feeding rhythms. The human circadian system synchronizes with, or entrains to, the light/dark cycle (sunrise/sunset) to promote activity and food consumption during the day and rest at night. However, strict work schedules and nighttime light exposure impair proper entrainment of the circadian system, resulting in chronic circadian misalignment. Numerous studies have shown that chronic circadian misalignment results in poor health. Therefore,...

Advanced Fault Area Identification and Fault Location for Transmission and Distribution Systems

Wen Fan
Fault location reveals the exact information needed for utility crews to timely and promptly perform maintenance and system restoration. Therefore, accurate fault location is a key function in reducing outage time and enhancing power system reliability. Modern power systems are witnessing a trend of integrating more distributed generations (DG) into the grid. DG power outputs may be intermittent and can no longer be treated as constants in fault location method development. DG modeling is also...

Bacterially Expressed dsRNA Causes Gene Silencing in EAB

Lynne Rieske-Kinney
RNA interference (RNAi) is a naturally occurring, biological process in which RNA molecules inhibit gene expression or translation by neutralizing target mRNA molecules. Recent advances in our understanding of the RNAi mechanism have allowed its development as an emerging tool to protect against insect pests. The major challenge for efficient pest management using RNAi as a molecular bio-pesticide in the field is development of convenient and efficient methods for production, and practical delivery of stable...

EVALUATE PROBE SPEED DATA QUALITY TO IMPROVE TRANSPORTATION MODELING

Fahmida Rahman
Probe speed data are widely used to calculate performance measures for quantifying state-wide traffic conditions. Estimation of the accurate performance measures requires adequate speed data observations. However, probe vehicles reporting the speed data may not be available all the time on each road segment. Agencies need to develop a good understanding of the adequacy of these reported data before using them in different transportation applications. This study attempts to systematically assess the quality of the...

Development of a Muffler Insertion Loss Flow Rig

Jonathan Chen
Abstract: Mufflers and silencers are commonly used to attenuate noise sources such as internal combustion engines and HVAC systems. Typically, these environments contain mean flow that can affect the acoustic properties of the muffler components and may produce flow generated noise. To characterize the muffler performance, common metrics such as insertion and transmission loss and noise reduction are used in industry. Though transmission loss without flow is often measured and is a relatively simple bench...
