  • Public Opinion of Baltimore’s Floating Wetlands – 2013 and 2019

    Creator:
    Eddy, Laura
    Abstract:
    To help beautify the open water space in front of the National Aquarium, in 2010 the very first floating wetland islands in Baltimore’s Inner Harbor were deployed. Since then, floating wetlands have sprouted up in other parts of Baltimore’s Inner Harbor, including the Bond Street Wharf. The National Aquarium’s floating...

  • Evidence for Cross-Seasonal Effects: Insights from Long-term Data on Northern Pintail

    Creator:
    Zarzycki, Megan C.
    Abstract:
    Cross-seasonal effects, where conditions in one season can have consequences in a following season, can have population-level implications for migratory species. To assess the presence of cross-seasonal effects on a migratory dabbling duck population, we examined the relative importance of habitat conditions in multiple seasons on the subsequent productivity of...

  • Essays on environmental productivity

    Creator:
    Bellenger, Moriah J., 1980-
    Abstract:
    The following three essays explore the use of the directional output distance function (Chambers et al., 1996), an economic model originally developed to measure efficiency and productivity for multi-input and multi-output production processes, to assess performance for multi-attributed environmental processes. The first essay illustrates the use of the directional output...

  • An Ecoregion-Based Reference Condition and Classification Scheme for Determining Nutrient Criteria in Oregon Lakes

    Creator:
    Brenner, Jacqueline M.
    Abstract:
    The anthropogenic introduction of nutrients to water bodies has been shown to alter the structure and function of natural aquatic ecosystems, yet national EPA lake and reservoir nutrient criteria remain too broad for effective regional water quality management. This study uses a reference site approach to propose numeric nutrient criteria...

  • Modeling and analyzing processes with infrequent failures : implications for process monitoring policies

    Creator:
    Darabi, Shooka
    Abstract:
    Continues improvement of industrial systems require constant measuring process variation and eliminating extraneous variation whenever possible to push the target measures as close to the ideal value as possible. Statistical Processes Control (SPC) technique is a very efficient statistical technique for monitoring and controlling processes variation. In recent years an...

  • Improvements in the dosimetric models of selected benthic organisms

    Creator:
    Caffrey, Emily Amanda
    Abstract:
    The International Commission on Radiological Protection (ICRP) has modeled twelve reference animal and plant (RAP) species using simple geometric shapes in Monte–Carlo (MCNP) based simulations. The focus has now shifted to creating voxel phantoms of each RAP to advance the understanding of radiation interactions in nonhuman biota. The work contained...

  • Hydrologic and vegetation responses associated with restoration of wetlands in the Willamette Valley, Oregon

    Creator:
    Coleman, Gregory A.
    Abstract:
    I examined hydrological and plant community changes associated with the implementation of a restoration management plan in two riparian meadows located within an agricultural landscape of the central Willamette Valley, Oregon. I established exclosure fencing (a form of passive restoration) in one agricultural field and established fencing and plugged a...

  • Impact of lees content, nitrogen, and elemental sulfur on volatile sulfur compound formation in Vitis vinifera L. cv. 'Pinot noir' wine

    Creator:
    Kraft, Daniel N.
    Abstract:
    One of the most common problems in wine production is the formation of hydrogen sulfide (H₂S) and other volatile sulfur compounds (VSCs), which can mask positive aromas at low concentrations and result in unpleasant aromas such as rotten egg, cabbage, garlic, and rubber at higher concentrations. Despite the large body...

  • Light soaking in metal-halide perovskites

    Creator:
    Watts, C. Lowell
    Abstract:
    Despite climate change requiring the cutback of fossil fuel consumption, the world continues to increase its energy demands each year. To meet the ambitious goals outlined during the Paris Agreement in 2015, which set a goal to limit global warming to 1.5°C [1], changes in energy production methods are necessary....

  • Gadusol Production in Saccharomyces cerevisiae

    Creator:
    Holzwarth, Garrett
    Abstract:
    Gadusol is a UV-B-absorbent compound found in fish and other marine organisms where it is presumed to play a role as a sunscreen and antioxidant. In light of commercial potential as a replacement for problematic synthetic sunscreens, a process to produce recombinant gadusol in the yeast Saccharomcyces cerevisiae was investigated....
