Laboratory Refinement of 4.75 mm Superpave Designed Asphalt Mixtures
(2006-12-15)
In 2004 a pooled fund study was initiated to refine mix design criteria for 4.75mm NMAS Superpave designed mixes and field validate design criteria. Nine states were participants in this study, Alabama, Connecticut, Florida, ...
Determination of Elastic Constants and Damage in Ceramic Matrix Composites Using Ultrasonic Wave Speed Measurements
(2006-12-15)
MATLAB programs were developed to compute the elastic constants and damage of ceramic matrix composites using ultrasonic wave speed measurements. The matrix of elastic stiffnesses, C, relates the material stresses and ...
Understanding the Flow and Mixing Dynamics of Saline Water Discharged into Coastal Freshwater Aquifers
(2006-12-15)
Typically the origin of saltwater intrusion into coastal aquifers has been attributed to the reduction of freshwater flux (or head) in the aquifer. This intrusion is the most common natural source of saltwater contamination ...
Comparison of New Technology for Measuring Ride Quality
(2006-12-15)
Ride quality of a pavement is quantified by a statistical index. The statistical index and the profile device used to assess the index are major variables in pavement smoothness. Due to the wide range of these variables ...
Characterization of the iron center in cysteine dioxygenase and kinetic analyses of flavin binding by the alkanesulfonate flavin reductase
(2006-12-15)
Cysteine dioxygenase (CDO) and the flavin reductase, SsuE, are both important proteins in sulfur metabolism. CDO catalyzes cysteine oxidation which is a key step in cysteine metabolism in mammalian systems. SsuE is a flavin ...
Quantum Chemical Studies and Kinetics of Gas Reactions
(2006-12-15)
Potential energy surfaces and reaction mechanisms were calculated using various computational methods such as density-functional and wave-function methods. High-level computational methods were used to obtain accurate ...
Design and Properties of Novel Uranium-Containing Layered and Framework Materials
(2006-12-15)
Ten uranyl-containing frameworks and one layered material have been
synthesized under hydrothermal conditions. These compounds belong to eight structure
types, not previously described. They are constructed from uranyl ...
Roles of an 'Inactive' Domain in Catalase-Peroxidase Catalysis: Modulation of Active Site Architecture and Function by Gene Duplication
(2006-12-15)
Within biological systems iron is a transition metal that allows access to the benefits of molecular oxygen as an oxidant. However, with these benefits come grave consequences if the reactions are not strictly controlled. ...
Ion Selective Polymeric Membranes as Chemically Selective Coulometric Electrodes
(2006-12-15)
Potentiometric and optical ion sensors use highly selective lipophilic ionophores as a special additive in a plasticized PVC membrane have been thoroughly studied for application as a coulometric electrode. This dissertation ...
Economic Analysis of Various Reforming Techniques and Fuel Sources for Hydrogen Production
(2006-12-15)
Hydrogen is emerging as a future replacement fuel for the traditional fossil fuels that will be capable of satisfying our energy needs. Hydrogen may enable future energy systems to be cleaner, more reliable, and much more ...
Membrane Separation in Supercritical Antisolvent Process for Nanoparticle Production
(2006-12-15)
In supercritical antisolvent process to produce pharmaceutical nanoparticles, drug solution is injected into supercritical carbon dioxide. CO2 rapidly extracts the solvent, causing the drug to precipitate as micro- and ...
The impact of tobacco taxation on cigarette consumption: a case study of France
(2006-12-15)
This thesis investigates the relationship between tobacco taxes and the consumption of cigarettes in France. The goal of this thesis is to determine the impact of the recent successive increases in tobacco taxes on the ...
Pharmacokinetics of ketamine and lidocaine in serum and milk of mature Holstein cows.
(2006-12-15)
Ketamine and lidocaine are two commonly used anesthetics in veterinary medicine, with some animals occasionally being sent for slaughter following drug administration. The United States Department of Agriculture (USDA) ...
Heat Stress Induces Downregulation of Hippocampal Superoxide Dismutase-1; a Possible Mechanism for Heat-Related Neuronal Cell Death
(2006-12-15)
Exertional heat injury represents a major risk for people working or exercising in hot environments. Currently, no pharmacological therapies are available and little is known about the molecular response to heat stress in ...
Influence of the Chicken Major Histocompatibility Complex on the Pathogenesis of Bacterial Skeletal Disease, Chicken Infectious Anemia and Infectious Bronchitis
(2006-12-15)
Genetic resistance to several poultry pathogens has been unequivocally linked to the major histocompatibility B complex (MHC). Relatively few MHC association studies have been conducted during natural disease outbreaks, ...
Thermotolerance in Gossypium hirsutum
(2006-12-15)
Heat and drought are major factors that affect the annual cotton yield. Cotton farmers are always looking for plants that are more thermotolerant and drought tolerant to increase the yield. These characteristics can be ...
Vigilance in Columbian Ground Squirrels: The Effects of Kinship and Mechanisms of the Group-size Effect
(2006-12-15)
Behavioral observations of Columbian ground squirrels (Spermophilus columbianus) were made to investigate two factors that can affect vigilance: the group-size effect and the presence of kin. Vigilance was timed in over ...
