Ultimate Detectability Of Volatile Organic Compounds: How Much Further Can We Reduce Their Ambient Air Sample Volumes For Analysis?, Ki-Hyun Kim
Ki-Hyun Kim
To understand the ultimately lowest detection range of volatile organic compounds (VOCs) in air, application of a high sensitivity analytical system was investigated by coupling thermal desorption (TD) technique with gas chromatography (GC) and time of flight (TOF) mass spectrometry (MS). The performance of the TD-GC-TOF MS system was evaluated using liquid standards of 19 target VOCs prepared in the range of 35 pg to 2.79 ng per μL. Studies were carried out using both total ion chromatograms (TIC) and extracted ion chromatograms (EIC) mode. EIC mode was used for calibration to reduce background and to improve signal to noise. …
Economics Of Nuclear Power And Climate Change Mitigation Policies, Nico Bauer, Robert J. Brecha, Gunnar Luderer
Economics Of Nuclear Power And Climate Change Mitigation Policies, Nico Bauer, Robert J. Brecha, Gunnar Luderer
Physics Faculty Publications
The events of March 2011 at the nuclear power complex in Fukushima, Japan, raised questions about the safe operation of nuclear power plants, with early retirement of existing nuclear power plants being debated in the policy arena and considered by regulators. Also, the future of building new nuclear power plants is highly uncertain. Should nuclear power policies become more restrictive, one potential option for climate change mitigation will be less available. However, a systematic analysis of nuclear power policies, including early retirement, has been missing in the climate change mitigation literature. We apply an energy economy model framework to derive …

Planning For Sea Level Rise In Portland, Maine Using Robust Decision Making As A Guide, Sadie Lloyd
Muskie School Capstones and Dissertations
This paper evaluates the potential for Robust Decision Making (RDM) to guide communities preparing for the impacts of climate change, using sea level rise planning in Portland, Maine as a case study. RDM is a problem solving process that considers multiple outcomes and an uncertain future, and focuses on decisions that provide benefits regardless of which future scenarios develop, allowing for the adjustment of decisions over time to accommodate changes in the future. The flexibility of RDM makes it an appropriate model for decision makers and stakeholders unsure how to address impacts of climate change, an issue complicated by numerous …
A Comparison Of Qualitative And Quantitative Ecological Assessment Methods Of Mangroves In Southwestern Madagascar, Sondra Winders
A Comparison Of Qualitative And Quantitative Ecological Assessment Methods Of Mangroves In Southwestern Madagascar, Sondra Winders
Independent Study Project (ISP) Collection
Mangroves are unique, tropical, intertidal forests that, among many other important functions, serve as large carbon sinks for the sequestration of atmospheric CO2. This project qualitatively assessed the mangrove forest of Honko Mangrove Conservation and Education (Tulear, Madagascar) in conjunction with Blue Ventures for a proposed Plan Vivo carbon stock project. The qualitative results were then compared with quantitative measurements in order to determine the most effective method of ecological assessment. Sixty-three stands of mangrove forest covering 9.72km2 were identified and mapped. Level of harvest, species composition, density, canopy cover, dominant height, dominant DBH, forest condition and composition were compared …
Connecting Habitat Across Roads: Field Testing Mitigation Strategies For Reducing Road Mortality Of An Imperiled Butterfly, Rebecca Jalene Littlejohn
Connecting Habitat Across Roads: Field Testing Mitigation Strategies For Reducing Road Mortality Of An Imperiled Butterfly, Rebecca Jalene Littlejohn
Environmental Science and Management Professional Master's Project Reports
Roads impact wildlife in a variety of ways including fragmentation of populations, reduced access to habitat, and direct mortality from vehicle strikes. Such road effects likely impact the Oregon silverspot butterfly (Speyeria zerene hippolyta) at one of its few remaining sites. The Rock Creek-Big Creek population of this threatened fritillary butterfly species is bisected by highway 101 on the central Oregon coast. Habitat resources for S. z. hippolyta are found on both the east and west sides of the highway at this site, and vehicle-strikes have been found to cause mortality of some individuals crossing the highway. The …

City Of Virginia Beach, Virginia Shoreline Inventory Report Methods And Guidelines, Marcia Berman, Harry Berquist, Sharon Killeen, Carl Hershner, Karinna Nunez, Karen Reay, Tamia Rudnicky, Daniel E. Schatt
Reports
The data inventory developed for the Shoreline Inventory is based on a three tiered shoreline assessment approach. In most cases this assessment characterizes conditions that can be observed from a small boat navigating along the shoreline. The three tiered shoreline assessment approach divides the shorezone into three regions:
1 ) the immediate riparian zone, evaluated for land use; 2 ) the bank, evaluated for height, stability, cover and natural protection; and 3 ) the shoreline, describing the presence of shoreline structures for shore protection and recreational purposes. A combination of handheld GPS units and GPS registered videography were used to …
Thresholds Of Change In Decomposition Rate Along A Dune/Swale Transect On A Virginia Barrier Island, Dominic J. Graziani
Thresholds Of Change In Decomposition Rate Along A Dune/Swale Transect On A Virginia Barrier Island, Dominic J. Graziani
Biological Sciences Theses & Dissertations
Aboveground and belowground decomposition rates were determined along a barrier island dune/swale transect located on the Virginia Coast Reserve-Long Term Ecological Research Site using litterbags and wooden dowels. The objective was to determine the influence of fine scale changes in the environment on decomposition to identify any potential thresholds affecting decomposition rate. Wax myrtle (Morella cerifera L. Small) leaves and dowels of southern yellow pine wood were used as standard substrates to evaluate environmental influences on decay. Aboveground (F=6.494, p < 0.0001) and belowground (F=5.705, p < 0.0001) decay rates (yr-1) showed significant variation among litterbag/dowel locations. Aboveground decay rates (yr-1) ranged from 0.339 (Upper Dune station) …

Fecal Indicator Bacteria In Knitting Mill Creek With A Comparison Of Methods Used To Enumerate E. Coli, Manju Nagarajan
OES Theses and Dissertations
This research seeks to evaluate the impact of an urban, multi-use neighborhood on the bacteriological quality of water in Knitting Mill Creek, a blind arm of the Lafayette River, a sub-estuary of the lower Chesapeake Bay. A principal objective was to determine the effects of rainfall, a surrogate for run-off, on water-column concentrations of fecal-indicator bacteria (FIB). I collected water samples weekly (September 2009-December 2010) and biweekly (January 2010-December 2011) at a storm-sewer outfall and a nearby marina and quantified their E. coli and enterococci concentrations using Colilert-18 and Enterolert, most-probable-number assays. In addition, I took monthly samples for these …

A Comparison Study Of A Bird Population In Lake Alaotra: The Effects Of A Protected Area, Sonya R. Kaufman
Independent Study Project (ISP) Collection
Lake Alaotra, the largest lake in Madagascar, is well known for its diverse plant and animal communities. It is home to three critically endangered endemic species, the Alaotran gentle lemur (Hapelemur griseus alaotrensis), Alaotra Little Grebe (Tachybaptus rufolavatus), and Madagascar pochard (Aythya innotata). Widespread habitat destruction by fire and clear-cutting is destroying the marshland vegetation of the lake, and siltation from erosion runoff and rice field creation is resulting in the ever-decreasing size of the lake. This study looked at the effectiveness of the protected area, Park Bandro, in preserving species diversity, relative abundances, …

Shoreline Evolution: Westmoreland County, Virginia Potomac River And Rappahannock River Shorelines, Donna A. Milligan, Christine Wilcox, C. Scott Hardaway Jr., Mary C. Cox
Reports
Westmoreland County is situated along the Potomac River and Rappahannock River. Through time, the County’s shoreline has evolved, and determining the rates and patterns of shore change provides the basis to know how a particular coast has changed through time and how it might proceed in the future. Along Chesapeake Bay’s estuarine shores, winds, waves, tides and currents shape and modify coastlines by eroding, transporting and depositing sediments. The purpose of this report is to document how the shore zone of Westmoreland County has evolved since 1937. Aerial imagery was taken for most of the Bay region beginning that year …
