Polycyclic Aromatic Hydrocarbons in Biochar and Their Bioavailabilty
(2017-12-08)
Biochar may be utilized as a soil-amendment to sequester carbon and enhance soil fertility through improved nutrient retention, increased plant-available water, and improved drainage for excess water. Before biochar can ...
Online vs. Traditional Classroom: An Examination of Public Speaking Anxiety in Community College Students
(2017-12-07)
Most people admit to having some degree of public speaking anxiety (Hickerson, 1998). This study examined the public speaking anxiety levels of students enrolled in an online and traditional public speaking course. This ...
Effect of Lightweight Aggregate on Early-Age Cracking of Mass Concrete
(2017-12-06)
Early-age cracking in mass concrete structures is a severe problem which could lead to long-term serviceability related problems in the structure. In this dissertation, the effect of using lightweight aggregates (LWAs) on ...
A Guideline to Facilitate Over the Air Communication in a Disaster Scenario
(2017-12-06)
During and directly following a disaster information is key. Not only getting information to the people that are in crisis but also getting data and reports out of the affected area so that relief agencies can act as quickly ...
Plant growth-promoting rhizobacteria (PGPR) mediate interactions between abiotic and biotic stresses in cool- and warm-season grasses
(2017-12-06)
Non-pathogenic, soil microbes that occupy the rhizosphere can influence plant growth and induce changes in the plant’s physiological, chemical, metabolic, molecular activities; influencing plant-microbe interactions with ...
Combining Ability of Channel Catfish, Ictalurus punctatus, Females and Blue Catfish, I. furcatus, Males for Early Growth, Growth Variation, Disease Resistance, and Carcass Yield of their Progeny
(2017-12-06)
The hybrid between channel catfish (I. punctatus) females and blue catfish (I. furcatus) males is considered the best catfish genotype for commercial catfish farming due to their faster growth rate, better survival rate, ...
Learning Partnerships in a Sustained Turnaround School: A Social Network Approach
(2017-12-06)
Turnaround schools had gained attention since the Bush Administration and No Child Left Behind. Studies were published frequently on the blueprints of turnaround and sustainability in which leadership was a focal point. ...
Benefits of Mindfulness in the Workplace: The Effects of Mindful Practices on Counterproductive Workplace Behaviors and Organizational Citizenship Behaviors
(2017-12-04)
Mindfulness research has been growing in its scope of having an influencing impact within organizational settings. A goal of this study was to add to the ongoing research by including situational factors, as they might ...
Microfluidic Circuit Designs for Nanoliter-Scale Flow Control and Highly Sensitive Quantitative Bioanalysis
(2017-12-04)
Within this dissertation, we have developed several new microfluidic circuit components that permit precise flow control at the nanoliter scale, and we have demonstrated their successful applications in either proof-of-concept ...
Thermal-Aware File and Resource Allocation in Data Centers
(2017-12-04)
After addressing the issue of reducing power consumption by computing nodes in data centers, in recent years, computer scientists are focusing on reducing cooling cost of the data centers, thereby making the data centers ...
Solution Approaches to Large Scale Multistage Stochastic Programs with Endogenous and Exogenous Uncertainty
(2017-12-01)
The focus of this dissertation is the investigation of approaches to address the computational challenges of solving multistage stochastic programs (MSSPs) with both endogenous and exogenous uncertainty. My work to date ...
Statistical Models of Nominally Flat Rough Surface Contact
(2017-12-01)
In this dissertation, the linear elastic contact between a nominally-flat rough surface and a rigid flat is studied analytically and numerically. When the roughness is excluded from the surface, the corresponding contact ...
Prevention and Pathogenesis of Avian Infectious Bronchitis: The Role of Infectious Bronchitis Virus Spike Proteins in Cell Attachment and Protective Immunity
(2017-12-01)
Infectious bronchitis virus (IBV) evolves by genetic diversity and selection resulting in continuous emergence of new virus phenotypes. Spike (S) protein is responsible for virus entry. The S1 subunit of the S glycoprotein ...
