Abundance and Diversity of Culturable Bacteria from Healthy and Suspect White Plague Type II-infected Corals in the Flower Garden Banks National Marine Sanctuary

Santora, Karen A. (2008-06-12)

The increasing number and geographic spread of coral diseases over the past three decades is threatening the diversity and viability of coral reef ecosystems. Little is known about the causes of disease outbreaks in ...
Accelerating the Adaptive Tempering Monte Carlo Method with CUDA Graphics Processing Units

Hall, Clifford T. (2013-08-15)

Molecular Dynamics (MD) has been and continues to be a popular method of molecular simulation because it is easily parallelizable. Parallel programming has become less burdensome for the science community, and competition ...
Accommodating Low Altitude Autonomous UAS Flight Within the National Airspace System

Seitz, Christopher

This thesis identifies trends in Unmanned Aircraft Systems (UAS) development and examines the status of UAS integration into the National Airspace System of the United States. The current states of Federal Aviation ...
Accuracy and Completeness as Measures of the Quality of Volunteered Point-Feature Geospatial Data and Evaluation of the Effect of Demographics on that Quality

Mullen, William F. (2014-05)

Over the last several years there has been a tremendous growth in the generation of Volunteered Geographic Information (VGI) data. The assessment of the quality and accuracy of VGI contributions, and by extension the ...
Acetylation as a Regulatory Mechanism of Chitinase Activity in Francisella tularensis subsp. novicida

Ii, Alexandra

Francisella tularensis is the causative agent of tularemia and is considered a Category A, Tier 1 biological threat agent. We and others have shown that Francisella tularensis forms biofilms in vitro , and we have ...
Acriflavine as a Novel Venezuelan Equine Encephalitis Virus Therapeutic

Hooper, Idris (2013-09-09)

Venezuelan equine encephalitis virus (VEEV) is a positive-sense ssRNA virus whose transmission has increased in Central and South America with cases being reported in the southern United States. VEEV can infect humans ...
Adaptive Management in the Chesapeake Bay Total Maximum Daily Load (TMDL) Program: How Do Local Watershed Managers Address Uncertainty and Use Adaptive Management?

Friesner, Richard K. (2015)

The Chesapeake Bay Total Maximum Daily Load (TMDL) is a federal action the Environmental Protection Agency (EPA) established to create a nutrient and sediment reduction strategy for the Chesapeake Bay based on contributions ...
An Additionality Approach to Global Blue Carbon Conservation

Butt, Myra T

Recent reports project an increase in atmospheric carbon dioxide levels significantly greater than what has been previously projected. One way to combat these changes is by conserving “blue carbon” ecosystems. Blue carbon ...
An Adenocarcinoma Case Study of the BaFL Protocol: Biological Probe Filtering for Robust Microarray Analysis

Thompson, Kevin (2009-02-09)

Microarrays are high throughput data measurement technologies; those that assay gene expression levels allowing investigators to simultaneously estimate the level of thousands of cellular transcripts present in a sample ...
Aerosol Monitoring from Space Using MODIS AOD Measurements over the Jing-Jin-Ji Region of China During 2000-2017

Fei, Xiqi

With more severe smog events reported in China, increasing attention has been attached to air quality in China. Aerosols, the minute solid or liquid particles suspended in the atmosphere, have an immense effect on air ...
Aerosol-Cloud-Radiation Interaction Studies with GEOS-4 Model and Comparison with Observations

Bhattacharjee, Partha Sarathi (2011-08-22)

Increasing human population and rapid urbanization in the last two decades have caused a sharp rise in anthropogenic aerosols particularly over South and East Asia. Numerous studies have shown that aerosols play an ...
Aerosol-Radiation-Climate Interactions over the Gangetic-Himalayan Region

Gautam, Ritesh (2008-12-15)

A growing body of evidence indicates that tropospheric aerosols, a major component of the global climate system, significantly influence the Earth’s radiation budget and climate forcings. Their multi-faceted impacts on ...
AGN and the Characteristics of their Host Galaxies

McAlpine, William (2013-08)

The vast majority of optically identified active galactic nuclei (AGNs) in the local universe reside in host galaxies with prominent bulges, supporting the hypothesis that black hole formation and growth is fundamentally ...
Algebra, Combinatorics, and Computation of Certain Tight Closure Invariants in Stanley-Reisner Rings

Thomas Ales (2019)

Tight closure was first introduced in the 1980's \cite{HHOrigin} by Hochster and Huneke to answer questions about invariant theory and the Brian\c{c}on-Skoda theorem. It has since come into its own as a fairly robust theory. ...
All-Atom Explicit-Solvent Replica-Exchange Molecular Dynamics Simulations of the Alzheimer’s Disease Aβ Monomer

Lockhart, Christopher (2015)

Using all-atom explicit-solvent replica-exchange molecular dynamics simulations, we explored the changes in the conformational ensemble of the Aβ monomer in various environments. In the simplest case, the Aβ monomer in ...
Allocating the Sources of Polycyclic Aromatic Hydrocarbons (PAHs) in Surficial Sediments from the Washington, DC Region with Particular Emphasis on Coal Tar Sealcoat

Nadrchal, David (2013-08-16)

Various sources of polycyclic aromatic hydrocarbons (PAHs) were analyzed that potentially influenced contamination levels in sediments from the Anacostia River in Washington, DC and surrounding area. Sources of PAHs ...
Altered Mitochondrial Dynamics in Venezuelan Equine Encephalitis Virus Infected Cells

Brooks-Faulconer, Taryn

To establish productive infection, viruses profoundly alter both the intracellular environment and the cellular function. Mitochondria are critically important cellular organelles that generate energy and ensure cell ...
An Analysis and Examination of Cruise Infrastructure Indicators, Flux Dynamics, and Destination Port Viability

Nyberg, John Everett (2022)

Cruise ship transportation and tourism can provide an opportunity to increase tourist visits and improve national and regional infrastructures. However, lack of planning and proper preparation by national authorities and ...
An Anisotropic and Asymmetric Material Model for Simulation of Metals Under Dynamic Loading

Haight, Sean (2016)

The purpose of this research is to develop a fully-tabulated, anisotropic, asymmetric, strain rate, and temperature dependent material model for solid finite elements. Physical testing of several metallic materials has ...
An Economic Analysis of the Potential 'Voluntary' Reductions of Nutrients from Agriculture to the Chesapeake Bay from the Shenandoah Soil and Water Conservation District, Virginia

Pindilli, Emily (2015)

This study addresses the lack of an in-depth assessment of field-level costs for implementing agricultural best management practices (BMPs). An economic analysis of the potential contribution of `voluntary' reductions of ...
