Humic Acids Resistant Gene Quantification Assay in Soils
(2011-05-17)
Humic acids are the most commonly reported group of inhibitors in environmental samples. Due to the ubiquity and abundance of humic acids in the environment, they are often co-extracted along with the nucleic acids and ...
Bioconversion of Pulp and Paper Mills Sludge and Prehydrolysate Stream into Ethanol and Cellulase Enzyme
(2011-05-17)
In the first part of this dissertation, two different types of paper mill sludges, primary sludge and recycle sludge, were evaluated as a feedstock for bioconversion to ethanol. The sludges were first subjected to enzymatic ...
Two-year Bark and Ambrosia Beetle Diversity Study at the Talladega National Forest in the Southeastern United States
(2011-05-16)
Over two year period (March 2008 to February 2010), bark and ambrosia beetles were captured in three different trap types (intercept panel, flight intercept and pitfall) at the Talladega National Forest in Chilton, Bill ...
Rank Based Methods for Repeated Measurement Data
(2011-05-16)
This dissertation considers rank based methods for one sample and two sample repeated measurement data. As a specific example, in Chapter 2, this dissertation considers nonparametric tests for selective predation. ...
A Non-contact Method for Sensing Tire Contact Patch Deformation Using a Monocular Vision System and Speckled Image Tracking
(2011-05-16)
A full-field, non-contact deformation sensing system was developed with an application for tires. Using an image tracking algorithm, in-plane displacements and their gradients were calculated. Furthermore, the effects of ...
Reliability of Solder Attachment Options with Lead Free for 0.4 mm Micro BGA Packages
(2011-05-16)
Electronic Modules have become an integral part in Automobiles. User friendly applications in Automobiles require high reliable electronic components to perform in harsh temperature ranges of -40 C to 165 C. Micro-electronic ...
Efforts towards the Detection of Perturbations in the Earth’s Magnetic Field: Design and Development of Solid State Sensor Array
(2011-05-13)
The following thesis provides a detailed description of the design and development of magneto-resistive unexploded ordinance (UXO) sensor array to detect the perturbations in the Earth’s magnetic field due to the presence ...
Measuring the Effects of Bridge Deck Replacement Methods on Construction Performance Factors
(2011-05-11)
The objective of this research was to develop and evaluate a methodology for measuring the effect of various bridge deck replacement methods on the total cost, schedule, and road user costs of a bridge project. Steps are ...
Transfer Length in Bulb-Tee Girders Constructed with Self-Consolidating Concrete
(2011-05-11)
This thesis is focused on the transfer bond behavior of self-consolidating concrete (SCC) relative to conventionally vibrated concrete (CVC) in full-scale, plant-cast, prestressed concrete bulb-tee girders for implementation ...
Process Control Factors for Continuous Microbial Perchlorate Reduction in the Presence of Zero-Valent Iron
(2011-05-11)
Water is a staple of civilization, and in the event of drinking water contamination the use of the contaminant’s source should be discontinued. Alternatively, a technology that can remove the contaminant from the water ...
