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 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 ...
An Evaluation of Metaphors in Climate Change Discourse

Walsh-Thomas, Jenell Marie (2016)

Anthropogenic climate change is currently one of the biggest threats facing the human population across the globe. Most Americans, however have little understanding of this threat, and as a result may be ill-prepared to ...
An Evaluation of Social Goals in Philippine Marine Protected Areas

Shah, Alexandra (2016)

The Philippines has a long history of protecting marine resources and limiting resource extraction and has been a world leader in marine protected areas (MPA) establishment, with over 1800 MPAs (Cabral et al. 2014). ...
Analysis of a Reaction-diffusion System with Local and Nonlocal Diffusion Terms

Tatum, Richard D. (2010-10-29)

Reaction-diffusion describes the process in which multiple participating chemicals or agents react with each other, while simultaneously diffusing or spreading through a liquid or gaseous medium. Typically, these processes ...
Analysis of Environmental Impacts of Large-scale Wind Farms Using Remote Sensing

Walsh-Thomas, Jenell M. (2012-06-18)

Wind energy is increasingly becoming a prevalent alternative, renewable energy resource as societies worldwide are attempting to reduce their carbon footprint in an effort to mitigate the negative effects of climate change ...
Analysis of Experimental Wood Chipper Trauma on Bone

Domenick, Kenneth (2012-06-12)

In the literature and research relating to human corpse dismemberment and mutilation, there are few studies focusing on wood chipper induced trauma. Most of what is known about wood chipper trauma is based on a handful of ...
Analysis of North Atlantic Tropical Cyclone Intensify Change Using Data Mining

Tang, Jiang (2010-05-20)

Tropical cyclones (TC), especially when their intensity reaches hurricane scale, can become a costly natural hazard. Accurate prediction of tropical cyclone intensity is very difficult because of inadequate observations ...
An Analysis of Phase Separation Processes for Stochastic and Nonlocal Extensions of the Classical Phase-Field Model

Hartley, Tina R. (2008-08-07)

Phase separation in composite materials, or materials that are made up of two or more different components, is a process in which the material separates over time into regions of predominantly one component or the other. ...
An Analysis of the Potential Direct or Indirect Influence Exerted by an Al Qaeda Social Network Actor on Future Biological Weapon Mission Planning

Baken, Denise (2007-11-21)

The current conflict known as the “War on Terror” pits several sovereign states (United States and its Allies) against a non-state entity. This entity, al Qaeda, is a global social network with religious doctrine adherence ...
Analysis of Volunteered Geographic Information for Improved Situational Awareness during No-Notice Emergencies

Oxendine, Christopher E. (2013)

During a terrorist attack, evacuees face uncertain risks when deciding which route to utilize while trying to evacuate. Immediately following an attack, information is very limited or non-existent. Emergency services ...
Analytical and Computational Methods for Fluid-Structure Interaction Applications to Aneurysms

Samuelson, Andrew Neil (2011-08-22)

In this dissertation, we develop analytical and computational models for understanding soft tissue mechanics, fluid dynamics, and their interaction. Despite major advances in this area, there is still a need for more ...
Analytical Evaluation and Mechanistic Elucidation for Solvent Degradation of Polymeric Materials

Daniels, Grant C (2015-03-24)

Polymeric coating materials have been used for decades to protect various substrates from degradation, such as corrosion, which can cause failure of important aspects in vehicles and buildings. The proper removal of ...
Analyzing Contribution Patterns of Volunteered Geographic Point Features in Relation to Errors and Demographics

Jackson, Steven Patrick (2014-05)

This dissertation explores the relationship between the contribution patterns of volunteered geographic point features in relation to error and demographic properties. Recent research on Volunteered Geographic Information ...
Analyzing Photovoltaic Potential Using a Geographic Information System: A Case Study of Prince William County Public Schools

Holstein, Brandy (2015-08-19)

This thesis researches the potential of rooftop photovoltaic installations on public school buildings using insolation maps and data created using geographic information systems. Electricity is a fundamental need; however, ...
Analyzing the Influence of African Dust Storms on the Incidence of Coral Disease in the Caribbean Sea using Remote Sensing and Association Rule Data Mining

Hunter, Heather E (2014-06-02)

It is estimated that approximately 11% of the historical extent of coral reefs is already lost, and an additional 16% severely damaged (Gardner et al., 2003). In the Caribbean Sea, alone, approximately 90-95% of a major ...
Analyzing the Relationships Between Hazard Vulnerability Science and Disaster Management Policy and Practice: A Case Study of Atlantic Hurricanes

Alexander, David Jean-Paul (2016)

Vulnerability indices have been used extensively in disaster management, and the social vulnerability index (SoVI) has been regarded as the most popular despite its appropriateness and performance not being validated ...
