Analysis Of Expedient Field Decontamination Methods For The Xmx/2l-Mil High-Volume Aerosol Sampler, Brandon C. Laroche
Theses and Dissertations
The XMX/2L-MIL is a high volume air sampler used by the Air Force Bioenvironmental Engineering community to collect biological aerosols. Without a verified decontamination technique, however, the XMX cannot be used effectively. The objective of this study was to evaluate several proposed methods for expedient field decontamination of the XMX. This study centered on the inactivation of Bacillus atrophaeus spores and vegetative Erwinia herbicola organisms from the XMX inner canister. The goals in this investigation were twofold: 1) to verify the antimicrobial efficacy of a 10% bleach solution and 2) to determine if wiping the components with a bleach-soaked paper …

Development Of The Mask Scentometer, A Comparison Of Ambient Odor Assessment Methods, And Their Application In Ground Truthing Atmospheric Dispersion Models, Christopher G. Henry
Department of Biological Systems Engineering: Dissertations and Theses
This dissertation is organized as four stand-alone papers. Paper No. 1 describes the development of the Mask Scentometer and reports dilution ratios measured during use by twelve different people. Dilution ratios at the Mask Scentometer’s five dilution-to-threshold (D/T) settings were found to be 0.35, 1, 2, 4.5 and 18. In Paper No.’s 2 and 4, ambient odor assessment methods were compared in both controlled laboratory conditions and in the field. Laboratory analysis of ambient air samples using dynamic triangular forced-choice olfactometry (DTFCO) did not correlate well with any of the ambient odor assessment methods. Average intensity-predicted D/T was roughly five …
Social Behaviors Of Modern And Indigenous Peoples Impacting The Ecology Of The Amazon Rain Forest In Brazil, Josef W. Schaffer
Social Behaviors Of Modern And Indigenous Peoples Impacting The Ecology Of The Amazon Rain Forest In Brazil, Josef W. Schaffer
Earth and Soil Sciences
Human induced disruption of the environment is prevalent in every culture. In Brazil, the effects of massive deforestation have become apparent since the nineteen eighties. However, along with deforestation, and a coinciding loss in an economic resource for the country, is a significant loss of natural habitat and species extinction. The Amazon in Brazil contains a large proportion of the world’s species diversity that is threatened by the socio-economic activities of modern Brazilian culture. Historically and presently, indigenous groups have contributed to insignificant levels of ecological disruption and are themselves threatened by the activities of modern Brazilians. The effects of …

Palaeoecology: A Tool To Improve The Management Of Australian Estuaries, Krystyna M. Saunders, Kathryn H. Taffs
Palaeoecology: A Tool To Improve The Management Of Australian Estuaries, Krystyna M. Saunders, Kathryn H. Taffs
Dr Kathryn H Taffs
Addressing environmental problems in estuaries is a worldwide problem. Establishing benchmarks and targets for management is critical, whether the aim is conservation, restoration or ‘sustainable wise use’. Palaeoecological techniques have rapidly improved during the past decade, particularly with advances in methods that allow high resolution quantitative assessments of environmental change, allowing pre-impact conditions, the rate, extent and direction of change, and range of natural variability to be determined. Australian estuarine ecosystems are qualitatively different to the often more well-studied estuaries in North America and Europe, which means site-specific studies of Australian estuaries are needed to inform management. While a potentially …

The deployment of thousands of wind energy facilities required to meet various renewable energy targets will bring changes to the nation’s landscapes, communities, and economies. Identifying and reconciling the trade-offs that inevitably arise from projects such as locating wind energy facilities is a major challenge to successfully meeting renewable energy targets. These complex challenges span scientific disciplines, involve multiple scales, lack well-defined solutions, and involve public values. Integrated assessment has been used effectively to address a number of complex challenges, ranging from climate change to “dead zones” in the Gulf of Mexico. The intent of this integrated assessment project, and …

Provenance Signatures Of The Antarctic Ice Sheets In The Ross Embayment During The Late Miocene To Early Pliocene: The Andrill And-1b Core Record, Franco M. Talarico, Sonia Sandroni
ANDRILL Research and Publications
Significant down-core modal and compositional variations are described for granule- to cobble-sized clasts in the Early Pliocene to Middle/Late Miocene sedimentary cycles of the AND-1B drill core at the NW edge of the Ross Ice Shelf (McMurdo Sound).
Long-term shifts in compositional patterns outline an evolving provenance which is interpreted as reflecting the combined effects and complex interactions among variations in ice volume, ice flow patterns and paleogeographic changes linked to the local tectonic and volcanic activity. High-frequency variations and the petrological features of the basement clast fraction provide direct information about the potential source regions during both glacial maxima …
Acid Rain: The Effects, Torrey Mortimer
Acid Rain: The Effects, Torrey Mortimer
Social Sciences
In a world experiencing increasing population, urbanization, and developing nations looking to compete on a global market with post-industrial nations, the effects of acid precipitation require greater consideration. As the world’s energy demand rises, and with the cheapest and most abundant source of energy being coal, the occurrence of acid precipitation is on the rise.
The goal of my project is to research and report on the effects of acid deposition on humans, animals and the environment that surrounds them. When I have completed my project, I hope to be able to explain the impacts that acid deposition has on …
Strategies For The Fusion Of Satellite Fire Radiative Power With Burned Area Data For Fire Radiative Energy Derivation, Luigi Boschetti, David P. Roy
Strategies For The Fusion Of Satellite Fire Radiative Power With Burned Area Data For Fire Radiative Energy Derivation, Luigi Boschetti, David P. Roy
GSCE Faculty Publications
Instantaneous estimates of the power released by a fire (Fire Radiative Power, FRP) are available with satellite active fire detection products. Integrating FRP in time provides an estimate of the total energy released (Fire Radiative Energy, FRE), which can be converted into burned biomass estimates needed by the atmospheric emissions modeling community. While straightforward in theory, the integration of FRP in time and space is affected by temporal and spatial undersampling imposed by the satellite sensing and orbit geometry, clouds, and active fire product omission errors. Combination of active fire FRP estimates with independently derived burned area maps provides the …

Effects Of Re-Grown Forest Habitat On Lemur Catta Behavior, Sophie Ackoff
Effects Of Re-Grown Forest Habitat On Lemur Catta Behavior, Sophie Ackoff
Independent Study Project (ISP) Collection
This study examines the effects of re-grown forest habitat on L. catta behavior at Berenty Private Reserve in Southern Madagascar during the early wet season. Evaluation of the reforested area versus natural forest revealed significant differences in species composition and food availability. Though the re-grown forest showed signs of forest regeneration and total greater food availability, the natural forest of Malaza proved to contain more preferred food sources for L. catta. Behavioral observations were collected over eight full-day troop follows and showed significant differences in feeding behavior, activity budget, and intra-troop and inter-troop aggressions. The WELL troop in Ankoba, the …
Effects Of Tide Gate Replacement On Water Temperature In A Freshwater Slough In The Columbia River Estuary, Sara Ennis
Effects Of Tide Gate Replacement On Water Temperature In A Freshwater Slough In The Columbia River Estuary, Sara Ennis
Environmental Science and Management Professional Master's Project Reports
Dramatic declines in salmon populations in the Pacific Northwest have brought new attention to the importance of estuarine rearing habitats. Levees and tide gates used to convert estuarine wetlands into farmland have reduced available habitat by more than half of historical levels. Recent efforts to restore estuarine habitats include tide gate replacement, though this method has been poorly studied. As a key indicator of salmon habitat suitability, temperature was used to evaluate the effects of tide gate replacement in a tidally influenced freshwater slough in the Lower Columbia River estuary. Three tide gates in the largest slough on Tenasillahe Island …

A Survey Of Drought Impacts And Mitigation Planning In Kentucky, Crystal Jane Bergman
Masters Theses & Specialist Projects
Drought is a well-known and costly climate-related natural hazard. Unlike other climate-related natural hazards, droughts are usually long in duration and may cover a large region, the physical boundaries of areas affected by drought are sometimes arbitrary, and the impacts are sometimes difficult to identify. Climate records since 1895 show that drought has occurred periodically in Kentucky. The drought of 2007 was the most recent drought to affect Kentucky and is the primary focus of this research. The purpose of this research is to identify impacts of drought and potential vulnerabilities to various drought impact sectors in Kentucky so that …

Wind Power West Michigan - Project Overview, Erik Edward Nordman
Technical Reports
Wind energy has the potential to be an environmentally sensitive alternative to fossil fuels because wind is renewable and can be used to generate electricity without emitting greenhouse gases and other pollutants. Michigan’s coastal zones possess abundant wind resources. However, wind energy development might present challenges for tourism-dependent lakeshore communities. Poorly sited wind farms may interfere with other uses of the coast, such as recreation, commercial fishing, and nature preservation, and not all communities are prepared to manage these conflicts.

Lead Detection In Water: Using Hydroxyapatite And Atomic Absorption, Nicolas Cantarero
Department of Environmental Studies: Undergraduate Student Theses
Hydroxyapatite is a mineral that is very inexpensive, easily made, and binds well to lead. In this procedure its application will be paired with Flame Atomic Absorption Spectroscopy (Flame AA) to detect lead concentrations in water to ppb levels. While ppb concentrations of lead are too dilute to produce a response from the Flame AA by using Hydroxyapatite to concentrate lead molecules from a larger volume and dissolving the Hydroxyapatite into a smaller volume it may be able to produce a response. The method could provide an inexpensive, efficient, and accurate way to detect lead concentrations to the ppb level …
