STUDIES OF DYNAMIC RESPONSE OF LIQUID STORAGE TANKS (FOUNDATIONS, RINGS, VIBRATION, DISCS)
This dissertation consists of four parts. The first part deals with the response of liquid storage tanks to a vertical component of ground motion. Galerkin's method is used to solve this problem approximately, and its accuracy is established by comparing the results with those obtained by the exact modal superposition method. The effects of soil ...
Discovering and Calibrating Design Rules for Programming Adeno-Associated Virus Nanoparticles
Effective gene therapy must deliver therapeutic genes to disease sites while avoiding healthy tissue. However, engineering targeted gene delivery vectors to ensure exclusive delivery to diseased sites remains a challenge. Adeno-associated virus (AAV) is receiving increasing attention for its potential as a gene delivery vehicle because it offers ...
Nonnormality in the seismic response of primary-secondary systems
Response nonnormality is investigated for a yielding primary structure and a linear secondary system (P-S) subjected to a normally distributed ground acceleration. The nonlinearity considered is bilinear hysteretic (BLH) yielding in the primary structure. The coefficient of excess (COE), which is a normalized fourth cumulant function, is used as a ...
Evaluation of fuel ethanol releases in a pilot-scale aquifer tank: Source dynamics, NAPL migration and microbial community response
Ethanol is playing a key role in current discussions on energy, agriculture, taxes and the environment. This work addresses the potential environmental impacts and behavior of subsurface fuel-ethanol releases. A continuous-flow 8,150-L pilot-aquifer tank packed with sand was used to simulate two spill scenarios: (1) fuel-grade ethanol (E95, 95% v/v ...
Dynamic response of hazardous liquid-waste storage tanks used in nuclear facilities
This dissertation presents a comprehensive study of the dynamic response of storage tanks containing high-level radioactive wastes in nuclear facilities. Of the many issues that are peculiar to these systems, four important ones have been studied. Accordingly, the study is presented in four parts. The first part deals with the dynamic response of ...

Bacteria and fullerene: The microbial response to fullerene water suspensions
The current nanotechnology boom necessitates timely research into the health and environmental impacts of nanomaterials to enhance their eco-responsible manufacture, use, and disposal. Using the water-insoluble C60 as a model nanomaterial, the potential environmental impacts of a C60 water suspension, termed nC60, are here assessed with bacteria as ...
Informed Planning and Safe Distributed Replanning under Physical Constraints
Motion planning is a fundamental algorithmic problem that attracts attention because of its importance in many exciting applications, such as controlling robots or virtual agents in simulations and computer games. While there has been great progress over the last decades in solving high-dimensional geometric problems there are still many challenges ...
Magnetite nanoparticles for removal of arsenic from drinking water
Arsenic has become a major contaminant of concern due to the increased knowledge of its toxicological and carcinogenic effects on human health, causing the maximum contaminant level (MCL) to be lowered from 50mug/L to 10mug/L in the United States. Lowering the MCL requires improving current methods or developing new ones to remove arsenic from the ...
Nanoshell-assisted cancer therapy: Targeted photothermal tumor ablation
This thesis details the development of a targeted nanoshell therapy for cancer specific photothermal ablation. By attaching targeting antibodies or ligands to the nanoshell surface, these targeted nanoshells preferentially bind to tumor sites. When NIR light is applied over the tumor region containing nanoshells, the nanoshells heat, thus destroying ...
