Approaches To Studying Bacterial Biofilms In The Bioeconomy With Nanofabrication Techniques And Engineered Platforms., Michelle Caroline Halsted
Approaches To Studying Bacterial Biofilms In The Bioeconomy With Nanofabrication Techniques And Engineered Platforms., Michelle Caroline Halsted

Studies that estimate more than 90% of bacteria subsist in a biofilm state to survive environmental stressors. These biofilms persist on man-made and natural surfaces, and examples of the rich biofilm diversity extends from the roots of bioenergy crops to electroactive biofilms in bioelectrochemical reactors. Efforts to optimize microbial systems in the bioeconomy will benefit from an improved fundamental understanding of bacterial biofilms. An understanding of these microbial systems shows promise to increase crop yields with precision agriculture (e.g. biosynthetic fertilizer, microbial pesticides, and soil remediation) and increase commodity production yields in bioreactors. Yet conventional laboratory methods investigate these micron-scale …
Phylogenetics And Association Analyses Illustrate Substantial Cryptic Diversity Of A Newly Isolated Collection Of Cenococcum Geophilum, Jessica Velez
Phylogenetics And Association Analyses Illustrate Substantial Cryptic Diversity Of A Newly Isolated Collection Of Cenococcum Geophilum, Jessica Velez
Doctoral Dissertations
The ectomycorrhizal fungus Cenococcum geophilum is distributed worldwide across multiple climates and soil types and is known to positively associate with a multitude of plant genera, possibly contributing to plant ability to tolerate inorganic contaminants in a soil environment. New C. geophilum isolates are easily cultured from soils in a laboratory setting, making this an ideal candidate for a model species with which to study multiple plant-fungal effects across a collection of novel isolates. However, C. geophilum is also genetically complex and, at 178Mbp, features one of the largest fungal genomes, necessitating the use of the novel restriction-associated DNA sequencing …

This project addresses the lack of security on access roads to broiler poultry farms in Tennessee by creating a system that autonomously recognizes vehicles as they approach the farm property. Many of these farms lack gates with proper security, making them vulnerable to vandalism and risking their biosecurity. Allowing all feed trucks entry to the farms is a vital requirement of the design in order to avoid interrupting operations on the farm. To address this issue, this project utilizes a combination of automated license plate reading software and light detection and ranging sensors (LiDAR) to autonomously recognize a vehicle and …
Stability And Evolution Of Planar And Concave Slopes Under Unsaturated And Rainfall Conditions, Arash Hassanikhah, Eric C. Drumm

Natural slopes are often observed to have a concave, convex, or a combination concave/convex profile, yet constructed slopes are traditionally designed with planar cross-sectional geometry. In this paper, the stability of two planar slopes was compared with that of companion concave slopes, designed to have similar factors of safety (FOS) under gravity loading. The stability of these slopes was then investigated in response to a suction event followed by a precipitation event, and it was shown that both the planar and the concave slopes experienced similar changes in stability. Additional analyses were conducted with a simulated erosion mechanism to investigate …
