| As fossil fuel resources become more difficult to find, the cost of extraction becomes inherently more expensive. Thus, alternative energy solutions must be explored to meet exponentially increasing energy demand due to population growth and industrial development. Solutions that derive energy from alternative resources, including sunlight, wind, tides, and biomass, are in various stages of maturity, ranging from theoretical concepts to commercially available commodities. Power derived from biomass, for example, ... |

| Several prototype, fast-pyrolysis reactors were built and tested to explore various reactor configurations. A high-pressure, fast-hydropyrolysis reactor system was designed based on the prototype, cyclone-type, fast-pyrolysis reactor. In addition, experiments were completed using a micro-scale reactor to better understand the fundamentals of char formation during fast-pyrolysis and fast-hydropyrolysis. To study coal gasification in the presence of excess hydrogen, an optically accessible, high-pressure and high-temperature entrained flow gasifier was constructed. This ... |

 | Projected growth of aviation depends on fueling where specific needs must be met. Safety is paramount, and along with political, social, environmental, and legacy transport systems requirements, alternate aviation fueling becomes an opportunity of enormous proportions. Biofuels sourced from halophytes, algae, cyanobacteria, and weeds using wastelands, waste water, and seawater have the capacity to be drop-in fuel replacements for petroleum fuels. Biojet fuels from such sources solve the aviation CO2 ... |

| Marine ecosystems reflect the physical structure of their environment and of the biological processes they carry out. This leads to spatial heterogeneity and temporal variability, some of which is imposed externally, and some of which emerges from the biological processes themselves. The main focus of this thesis is on the formation of spatial patterns in the distribution of zooplankton arising from social interactions between individuals. In the Southern Ocean, krill ... |

| Subsurface microbial activity is critical in many bioengineering processes such as enhanced oil recovery, in-situ or enhanced bioremediation, and biomass plugging operations. To investigate biofilm formation, strain PHOO2 of the Azoarcus genus, which produces flocs in stationary growth phase was studied. Flocculation occurs as this gram-negative, denitrifying strain is grown anaerobically on a phenol carbon source. As stationary phase is approached, the phenol concentration diminishes and the hydrophilic cells become ... |

| One challenge in phytoplankton ecology is to measure species-specific physiological responses to changes in environmental conditions. Of importance are species such as the toxic dinoflagellate Alexandrium fundyense which inhabit coastal regions and are not usually dominant. The aim of this thesis was to identify physiological and behavioral diagnostics of A. fundyense from the Gulf of Maine, and use these indicators to evaluate field populations. Using a surface-specific monoclonal-antibody two methods, ... |

Nematoscelis difficilis (Crustacea, Euphausiacea) were collected in a persistent, eutrophic coastal eddy and in oligotrophic offshore waters of the California Current. The euphausiids were ... |

| Soils and vegetation are subjected to stress and disturbance under human foot traffic. This study was conducted to determine whether training at the U.S. Air Force Academy adversely impacted soils and vegetation. In the summer of 1998, the effects of training on bulk density, infiltration, soil water holding capacity, soil total C and N concentrations, soil C:N ratio, total above ground biomass, and litter layer were ... |

| The goal of this research program is to contribute to a fundamental understanding of the sources of optical variability in coastal ocean systems. This is being achieved through a field effort to make measurements of time series and spatial distributions of both apparent and inherent optical properties in the waters of Georges Bank and the Gulf of Maine. Optical properties are strongly affected by phytoplankton, ... |
