Ecology Of Viruses In Marine And Coastal Oxygen-Depleted Waters, Sophie Jurgensen

LSU Doctoral Dissertations

Deoxygenation of marine and coastal waters, both caused and exacerbated by a suite of abiotic and biotic factors, has been documented for more than sixty years. The incidence and severity of low-oxygen areas is predicted to expand globally in the coming decades. Despite their colloquial moniker “dead zones,” low-oxygen areas contain thriving and diverse microorganisms that have significant impacts on global biogeochemical cycles including contributing to positive feedback loops that further expand low-oxygen areas. While the diversity and activity of these microorganisms is beginning to be elucidated, the ecology of their viruses is particularly understudied. In this dissertation, I present …

Synthesis Of An Acinetobacter Baumannii Lipooligosaccharide Subunit, James M. Armstrong Ii

LSU Doctoral Dissertations

Acinetobacter baumannii is a Gram-negative, multi drug-resistant bacterium that was placed on the World Health Organization’s watchlist of drug-resistant bacteria. A. baumannii is an ESKAPE pathogen, one of six increasingly antimicrobial-resistant bacteria that are responsible for nosocomial infections. Alternative therapies, such as vaccines, are required to decrease the world’s reliance on antimicrobial agents. Specifically, glycoconjugate vaccines such as those used against Haemophilus influenzae B, Streptococcus pneumoniae, and Neisseria meningitidis are used globally and are highly effective. These vaccines consist of an antigenic bacterial glycan bound to a carrier protein. The glycan is usually a capsular polysaccharide (CPS), however, the notion …

Methods For Designing Compact And Deployable Origami-Inspired Flat-Foldable Spacecraft Antennas And Other Systems, Collin Ryan Ynchausti

Theses and Dissertations

There are times when it is desirable for devices to be stowed compactly, ``transported'' to the location of their desired use, and then deployed to another stable shape or configuration to perform their designed function. Origami-based mechanisms are beneficial in these cases due to their compact, folded nature and large deployments. Unlike traditional mechanical design, compliant mechanism and origami-based design approaches inherently have coupled characteristics, creating complex design problems. The research presented here discusses metrics, methods, and designs to aid in the design of origami-adapted and compliant mechanisms, focusing on the design case of deployable space systems. First, the hexagonal …

Annamdevula, Donald Pleshinger, Zara Ijaz, Josephine Jalkh, Raymond Penn, Deepak Deshpande, Thomas C. Rich, Silas J. Leavesley

Center for Translational Medicine Faculty Papers

Hyperspectral imaging (HSI) technology has been applied in a range of fields for target detection and mixture analysis. While HSI was originally developed for remote sensing applications, modern uses include agriculture, historical document authentication, and medicine. HSI has also shown great utility in fluorescence microscopy. However, traditional fluorescence microscopy HSI systems have suffered from limited signal strength due to the need to filter or disperse the emitted light across many spectral bands. We have previously demonstrated that sampling the fluorescence excitation spectrum may provide an alternative approach with improved signal strength. Here, we report on the use of excitation-scanning HSI …

No Safe Spaces: Institutionally Washed Out, Jordan Marie King

Online Theses and Dissertations

Abstract Prior literature has shown that black and brown bodies (BBB) are policed and victimized at higher rates than their white counterparts within the criminal justice system. The criminalization of school discipline is a microcosm of ‘big’ criminal justice. Criminal justice measures were implemented within schools as a means of maintaining ‘safety.’ Policing in schools perpetuates punishment disproportionality and maintains similar disproportionalities as the ‘big’ criminal justice system in terms of for whom and how how severely it is applied. Meaning that regardless of the school's demographics or student backgrounds, black and brown bodies are punished at a higher rate …

Community Role Models And Their Influence On At-Risk-Youth, Eliab Charles Caudio

Masters Theses

The youth in our communities are easily influenced. For this reason, they should not be left to govern themselves. More often than not, they have a few peers steering them in the wrong directions, enabling poor decisions, mostly to fit in, stand out, or some form of protection. Also, there are those who simply have no direction, wanting to live fast, grow up before their time and engage in high risk behaviors they consider having fun. The focus of my research aims to drive home the point that “consistent mentorship from successful adults” is an often overlooked solution in helping …
