Socio-Economic Analysis Of Fatal Crash Trends (Final Report), Adam Kirk, Jerry G. Pigman, Kenneth R. Agent

Kentucky Transportation Center Research Report

This report describes the analysis of fatal crash patterns and explores the impact of socioeconomic factors and safety regulations on statewide crash rates. This analysis separated statewide crash rates between 2002 and 2004 into two samples, 1) those with crash rates 25 percent greater than the average national rate and 2) those with crash rates lower than this threshold. Safety regulations and socioeconomic factors were identified as having a significant effect on crash rates, with socioeconomic factors showing a higher potential to explain differences in crash rates between the two samples.

Dump Truck Driver Crushed Between Trackhoe And Dump Truck, Kentucky Injury Prevention And Research Center

Fatality Case Reports--Motor Vehicle

On November 11, 2004, a 33-year-old male dump truck driver died when he was crushed between the driver’s side of the dump truck and the swinging counter-weight of an excavator (trackhoe). His dump truck became stuck in mud after the trackhoe loaded dirt into it so he walked to the on-site office and informed the owner. The owner located a bulldozer on site and drove it to the dump truck while the driver retrieved a chain from his personal pickup truck. The owner raised the blade so the driver could attach the chain to it. Raising the blade of the …

Rate Response Assessment From Various Granular Vrt Applicators, John P. Fulton, Scott A. Shearer, Stephen F. Higgins, Matthew J. Darr, Timothy S. Stombaugh

Biosystems and Agricultural Engineering Faculty Publications

Variable-rate technology (VRT) adds complexity to application equipment, thereby confounding the assessment of applicator performance. The intent of this investigation was to assess the rate response of various VRT granular applicators: two spinner spreaders (A and B), and two pneumatic applicators (C and D). Variable-rate (VR) tests were conducted to quantify the rate response characteristics (delay and transition times) for the applicators. A sigmoidal function was used to model the rate response for five of the six tests. Applicator A exhibited a linear response during decreasing rate changes. Results indicated that only applicator B demonstrated consistent delay and transition times, …

Economic Costs Of Low Safety Belt Usage In Motor Vehicle Crashes In Kentucky, Michael Singleton, Qing Xiao, Kenneth R. Agent

Kentucky Transportation Center Research Report

By passing legislation in 2006 to mandate primary enforcement of the Kentucky state law requiring safety belt use for motor vehicle occupants, the state could expect to realize an overall savings of at least $118 million in direct medical costs over the ten-year period from 2006 to 2015. Charges to Medicaid over that period would be about $34 million less than under the current secondary enforcement model. In addition, there would be at least $67 million saved in medical costs to commercial insurers, $2.3 million to Medicare, $3.3 million to Worker’s Compensation, and $11.2 million to other sources.

These savings …

The Chemical Species Of Aluminum Influences Its Paracellular Flux Across And Uptake Into Caco-2 Cells, A Model Of Gastrointestinal Absorption, Yuzhao Zhou, Robert A. Yokel

Pharmaceutical Sciences Faculty Publications

Aluminum (Al) can cause neurotoxicity, a low-turnover osteomalacia, and microcytic anemia. To test the null hypothesis that the chemical form (species) of Al does not influence its mechanism or rate of absorption from the gastrointestinal tract, Al flux across and uptake into Caco-2 cells was investigated. Caco-2 cells were grown on porous membranes mounted in vertical diffusion chambers or in 35-mm-diameter plastic cell culture dishes. When 8 mM ²⁷Al was introduced as the ion, citrate, maltolate, fluoride, or hydroxide, the apical to basolateral apparent permeability (P_app) of Al correlated highly with the P_app of lucifer yellow …

Corrosion Evaluation Of Mechanically Stabilized Earth Walls, Tony L. Beckham, Liecheng Sun, Tommy C. Hopkins

Kentucky Transportation Center Research Report

Numerous reinforced walls and slopes have been built over the past four decades in Kentucky, the United States, as well as worldwide. Tensile elements used in constructing low-cost reinforcing walls and slopes consist of metal polymer strips or grids. Although reinforced structures have been used extensively, the effects of corrosion on the metal tensile elements are unknown. Mechanically stabilized earth walls are expected to remain stable for many decades. An examination of the effects of corrosion of metal tensile elements used to construct these walls can provide invaluable data regarding the longevity of reinforced walls and slopes. Four mechanically stabilized …

Plant and Soil Sciences Faculty Publications

Diazinon [O,O-diethyl O-2-isopropyl-6-methyl(pyrimidine-4-yl) phosphorothioate] and imidacloprid [1-(1-[6-chloro-3-pyridinyl]methyl)-N-nitro-2-imidazolidinimine] are applied to lawns for insect control simultaneously with nitrogenous fertilizers such as urea, but their potential effect on urease activity and nitrogen availability in turfgrass management has not been evaluated. Urease activity in enzyme assays, washed cell assays, and soil slurries was examined as a function of insecticide concentration. Intact cores from field sites were used to assess the effect of insecticide application on urease activity in creeping bentgrass (Agrostis palustris Huds.) and bluegrass (Poa pratensis L.) sod. Bacterial urease fromBacillus pasteurii and plant …

Long-Term Maintenance Needs Planning, Doug Kreis, Lenahan O'Connell, Brian Howell

Kentucky Transportation Center Research Report

This research contributes to Kentucky’s knowledge base of long-term maintenance needs in two parts. Part 1 presents an estimate of the average revenue needed to maintain four categories of highway in the first fifteen years after each is built or resurfaced. Total maintenance costs per mile for four types of facilities in five AADT volume categories were estimated. The results suggest that Kentucky is not resurfacing all its roads in a timely manner. Part II presents background information on preventive maintenance programs in the states. A review of the states found two recurring themes. The first was the widespread adoption …

Runx-Dependent Expression Of Pkc Is Critical For Cell Survival In The Sea Urchin Embryo, Carrie Dickey-Sims, Anthony J. Robertson, Dawn E. Rupp, John J. Mccarthy, James A. Coffman

Physiology Faculty Publications

BACKGROUND: Runx transcription factors play critical roles in the developmental control of cell fate and contribute variously as oncoproteins and tumor suppressors to leukemia and other cancers. To discover fundamental Runx functions in the cell biology of animal development, we have employed morpholino antisense-mediated knockdown of the sea urchin Runx protein SpRunt-1. Previously we showed that embryos depleted of SpRunt-1 arrest development at early gastrula stage and underexpress the conventional protein kinase C SpPKC1.

RESULTS: We report here that SpRunt-1 deficiency leads to ectopic cell proliferation and extensive apoptosis. Suppression of the apoptosis by pharmacological inhibition of caspase-3 prevents the …

J-Resolved He I Emission Predictions In The Low-Density Limit, R. P. Bauman, R. L. Porter, Gary J. Ferland, K. B. Macadam

Physics and Astronomy Faculty Publications

Determinations of the primordial helium abundance are used in precision cosmological tests. These require highly accurate He I recombination rate coefficients. Here we reconsider the formation of He I recombination lines in the low-density limit. This is the simplest case, and it forms the basis for the more complex situation in which collisions are important. The formation of a recombination line is a two-step process, beginning with the capture of a continuum electron into a bound state and followed by radiative cascade to ground. The rate coefficient for capture from the continuum is obtained from photoionization cross sections and detailed …

Objective. The public has a high interest in seeking personal genetic information, which holds implications for health information seeking research and health care policy. Rapid advances in cancer genetics research promise early detection, prevention and treatment, yet consumers may have greater difficulty finding and using the information they may need to make informed decisions regarding their personal health and the future of their families.

Design. A statewide telephone survey was conducted of non-institutionalized Kentucky residents 18 years of age or older to investigate factors associated with the intention to seek cancer genetics information, including the need for such information seeking …

The Impact Of State Road Fund Debt Limits: An Empirical Analysis, Michael Moody, Merl Hackbart

Kentucky Transportation Center Research Report

States have been gradually increasing their reliance on debt financing to meet their transportation funding needs. Increased reliance on debt financing has been driven by the slow growth of highway and Road Fund revenue sources, resistance to tax expenditures, and restrictions placed on the use of General Fund revenue, in many states, for transportation projects. In light of states’ increasing reliance on debt financing for transportation, state officials and policy makers have shown greater interest debt management practices. One dominant practice across the states is the use of debt limitations. Debt limit policies vary widely from state to state. There …

Innovative Rapid Construction/Reconstruction Methods, Paul M. Goodrum, Yinggang Wang, Chris N. Jones, Philippe C. Fenouil, Donn E. Hancher

Kentucky Transportation Center Research Report

Innovative construction and reconstruction methods provide the opportunity to significantly reduce the time of roadway projects while maintaining the necessary quality of workmanship. The need for these “rapid” methods stems from the increase in traffic on Kentucky roadways coupled with the rise in conventional road and bridge construction methods. Conventional construction methods cannot maintain the demand for progress necessitated by the future needs of the Kentucky Transportation Cabinet, especially the current philosophy of “Get In, Get Out, and Stay Out.” This research documents a series of case studies that examined past projects which used innovative rapid construction methods. This document …
