  • Effects of aerosols on the properties of deep convective clouds

    Creator:
    Brown, Daniel A.
    Abstract:
    Aerosols are tiny particles that serve as nuclei for cloud droplet and ice crystal formation. Increases in aerosol concentration lead to clouds with smaller but more numerous droplets. Some recent studies have found evidence that ice crystal size in deep convective clouds is also reduced by elevated aerosol concentrations. In...

  • Response of marine stratus to successive polluting events by ships

    Creator:
    Sechrist, B.
    Abstract:
    Ship tracks have proven to be an ideal laboratory for studying the response of marine stratocumulus to an increase in aerosol pollution. Here the response of already polluted marine stratocumulus to further pollution was examined by studying the clouds where two ship tracks cross. 78 crossings of ship tracks were...

  • Ecological Consequences of Marine Debris: Understanding Large-Scale Species Transport on Tsunami Debris and Research Priorities in Oregon

    Creator:
    Gillman, Reva A.
    Abstract:
    The release of marine debris into the oceans and seas is a global issue of growing concern. These materials are harmful to marine environments and can also transport non-native species to novel habitats. Non-native species floating on marine litter is one of the lesser known impacts associated with marine debris....

  • Use of Targeted and Non-Targeted Analysis to Study Complex PAH Environmental Mixtures

    Creator:
    Chibwe, Leah
    Abstract:
    Polycyclic aromatic hydrocarbons (PAHs) are ubiquitous contaminants formed from the incomplete combustion of organic material. These contaminants are of concern because of their widespread presence in the environment and toxic properties. In addition, PAHs encompass a class of diverse compounds with varying physicochemical properties and exist in the environment as...

  • Poly- and perfluorinated alkyl substance release from landfills and landfill model reactors

    Creator:
    Allred, Brent McKay
    Abstract:
    Research and public concern of poly and perfluoroalkyl substances (PFASs) as environmental contaminants has increased significantly due to the increasing number of reports of their detection in humans and wildlife. PFASs have a number of commercial applications including surfactants, coatings, polymers, and levelers, which are used on consumer products like...

  • Hydraulic experiments on impact forces from tsunami-driven debris

    Creator:
    Ko, Harrison T.
    Abstract:
    Impact by an idealized shipping container on a column were observed for tsunami flow in a large-scale wave flume modeled at the O.H. Hinsdale Wave Research Laboratory at Oregon State University. Two specimen types, aluminum and acrylic, were tested; and each specimen was tested in two orientations, longitudinal and transverse....

  • Assessing steel bevel gear design alternatives for sustainability performance through unit manufacturing process modeling

    Creator:
    Eastwood, Michael D.
    Abstract:
    As the growth in demand for sustainable manufacturing continues, companies must begin to make conscious design decisions with regard to the sustainability of their products. This means balancing economics of production with environmental and social performance. Thus, design and manufacturing engineers must consider economic, environmental, and social aspects simultaneously when...

  • Assessment of Environmental Impacts of Wood Substitution in Commercial Construction

    Creator:
    Milaj, Kristina
    Abstract:
    In the residential sector, wood is the predominant construction material. In the commercial sector and in mid‐rise construction, the use of wood is limited because of a multitude of reasons, including building code restrictions, the perception of wood as a structural material, fire code requirements, and lack of knowledge and...

    Abstract:
    In this thesis, in order to understand why Buddhists in Southeast Asia protect rainforests and to establish a solid foundation for Buddhist environmental ethic, my first two tasks are to draw a clear picture regarding two major environmental concepts--nature and anthropocentrism--in Buddhism and to defend the claims that the Buddhist...

  • Sustainable apparel consumption : scale development and validation

    Creator:
    Zhang, Ruirui
    Abstract:
    he purpose of this project was to develop a scale to measure sustainable apparel consumption. This study used concept analysis to identify attributes of sustainable apparel consumption. Within an academic online database, a search for articles containing "sustainable consumption" in their titles was performed. Within each article, the attributes associated...
