BACKGROUND: HIV Associated Dementia (HAD) is a common complication of human immunodeficiency virus (HIV) infection that erodes the quality of life for patients and burdens health care providers. Intravenous drug use is a major route of HIV transmission, and drug use is associated with increased HAD. Specific proteins released as a consequence of HIV infection (e.g., gp120, the HIV envelope protein and Tat, the nuclear transactivating protein) have been implicated in the pathogenesis of HAD. In primary cultures of human fetal brain tissue, subtoxic doses of gp120 and Tat are capable of interacting with a physiologically relevant dose of cocaine, …

Outsourcing Of Kytc Project Delivery Functions, Donn E. Hancher, April Brenneman, Robin Meagher, Paul M. Goodrum

Kentucky Transportation Center Research Report

The rise in daily travelers on highways due to population growth, and higher quality and service expectations of the public, are putting increased demands on DOTs today. These demands, combined with decreasing staff sizes and changing resources, are causing DOTs to investigate alternative methods for accomplishing their essential functions. A major option is to contract out more of their work to external parties, commonly called “outsourcing .” The purpose of this project was to evaluate the potential effectiveness, benefits, concerns and implementation requirements of outsourcing by the Kentucky Department of Highways.

This report looks at current outsourcing practices in other …

Kentucky Transportation Center Research Report

This report summarizes the condition assessment of the pavement structure on I-65 between 97.5 to 102.5. Three types of equipment were used to evaluate the present condition of the pavement: falling weight deflectormeter, ground penetrating radar, and coring machine, Results indicated that durability of the existing concrete surface appears to be the most detrimental problem encountered in this survey. Load-transfer across transverse joint appear to be in acceptable ranges. Limited areas were identified to have less than four inches of D.G.A. beneath the concrete pavement. These areas have also been experiencing the most differential settlement. In addition several areas are …

Evaluation Of Methods To Limit The Time Taken To Investigate Crash Sites, Jennifer R. Walton, Monica L. Barrett, Kenneth R. Agent

Kentucky Transportation Center Research Report

Highway crashes have significant direct and indirect costs associated with them. Substantial sources of indirect costs are the congestion and delays that result from lane blockages or road closures while the crash is being investigated and the site cleared. In many cases, vehicles could be moved and roadways reopened very quickly, but this does not occur because of the need (or perceived need) to conduct a detailed investigation of the crash scene. The objective of this study was to identify opportunities to reduce the time required to investigate and clear crash scenes. This project includes a review of state and …

Bearing Capacity Analysis And Design Of Highway Base Materials Reinforced With Geofabrics, Tommy C. Hopkins, Liecheng Sun, Mikhail E. Slepak

Kentucky Transportation Center Research Report

The primary objective of this study was to develop and implement mathematical bearing capacity models originally proposed by Hopkins (1988, 1991) and Slepak and Hopkins (1993; 1995). These advanced models, which are based on limit equilibrium and are operated together, can be used to analyze the bearing capacity, or stability, of early construction of loads on a single layer of material, two-layered problems involving a layer of base aggregate and subgrade, and a foundation involving multiple layers of different materials, such as a flexible asphalt pavement. A Prandlt-type shear surface is used in the model analyses of layered foundations. In …

Molecular Hydrogen In Star-Forming Regions: Implementation Of Its Microphysics In Cloudy, G. Shaw, Gary J. Ferland, N. P. Abel, P. C. Stancil, P. A. M. Van Hoof

Physics and Astronomy Faculty Publications

Much of the baryonic matter in the universe is in the form of H₂, which includes most of the gas in Galactic and extragalactic interstellar clouds. Molecular hydrogen plays a significant role in establishing the thermal balance in many astrophysical environments and can be important as a spectral diagnostic of the gas. Modeling and interpretation of observations of such environments requires a quantitatively complete and accurate treatment of H₂. Using this microphysical model of H₂, we present illustrative calculations of prototypical astrophysical environments. This work forms the foundation for future investigations of these and …

It automatically records potential incidents when activated by sound (horns, clashing metal, squealing tires, etc.). The purpose is to detect patterns of crashes at intersections for use in implementing relevant improvements. Videos of incidents and near-incidents were obtained after AIRS was placed in service at an intersection in Louisville, Kentucky on July 22, 2001. Crash reports were obtained from January 1998 through September, 2004 to; a) compare to the available data from AIRS videos, and b) compare the crashes before and after various improvements were made. A traffic …

Speed Estimation For Air Quality Analysis, Mei Chen, Huafeng Gong

Kentucky Transportation Center Research Report

Average speed is an essential input to the air quality analysis model MOBILE6 for emission factor calculation. Traditionally, speed is obtained from travel demand models. However, such models are not usually calibrated to speeds. Furthermore, for rural areas where such models are not available, there has not been a reliable method for estimating speed.

In this study, a procedure was developed based on the Highway Economic Requirement System (HERS) speed model to estimate average speed using as input various data such as roadway characteristics and traffic conditions. This procedure was coded in MS Excel macro and can be attached to …

BACKGROUND: Recent advances in sequencing techniques leading to cost reduction have resulted in the generation of a growing number of sequenced eukaryotic genomes. Computational tools greatly assist in defining open reading frames and assigning tentative annotations. However, gene functions cannot be asserted without biological support through, among other things, mutational analysis. In taking a genome-wide approach to functionally annotate an entire organism, in this application the approximately 11,000 predicted genes in the rice blast fungus (Magnaporthe grisea), an effective platform for tracking and storing both the biological materials created and the data produced across several participating institutions was required.
