  • Aboveground biomass and ecosystem carbon pools in tropical secondary forests growing in six life zones of Costa Rica

    Creator:
    Cifuentes Jara, Miguel
    Abstract:
    Carbon sequestration in tropical secondary forests growing in all climates must be quantified to understand their potential role in adaptation and mitigation strategies of global climate change. Total aboveground biomass (TAGB), soil carbon, and total ecosystem carbon (TEC) were measured in 54 secondary forests growing along a broad bioclimatic gradient...

  • Vertical structure and aboveground biomass of tropical forests from lidar remote sensing

    Creator:
    Gonçalves, Fabio Guimarães
    Abstract:
    Methods for obtaining accurate, spatially explicit estimates of biomass density in tropical forests are required to reduce uncertainties in the global carbon cycle, and to support international climate agreements and emerging carbon markets. Three-dimensional (3-D) remote sensing techniques sensitive to the vertical structure of vegetation provide a unique opportunity for...

  • Integrating indigenous knowledge into the community development process : the Zimbabwean experience

    Creator:
    Munyaka, Golden
    Abstract:
    This study is a critical ethnography of my professional career as an educator born and raised in the Shona culture in Zimbabwe. In this metaphysical study I reconstruct a worldview that I consider to be representative of Shona customs and beliefs. Doing this project has challenged my own ethnic identity...

  • Marketing sophistication in the forest products industry

    Creator:
    Han, Xiaoou
    Abstract:
    In the forest products business and management literature, one common categorization of different types of innovation is product innovation, process innovation and business systems innovation. Forest products companies have long placed high emphasis on process innovations, which are related to yield maximization, manufacturing efficiency and operating costs reduction. This is...

  • Multiscale modeling of two-phase flows in microarchitectures with microfeatures

    Creator:
    Truszkowska, Agnieszka
    Abstract:
    Two-phase flows in microtechnology based devices are purposefully present in multiphase reactors, phase separators, analytical devices and others. Two-phase flows can also be an undesirable side effect occurring during operation due to phase transitions or, more commonly, introduction of surrounding air through equipment gaps and with process feed. In both...

  • What Lies Below: Options to Improve Sustainable Management of U.S./Mexico Transboundary Aquifers

    Creator:
    Welch, Christina, N.
    Abstract:
    Globally, as surface water quality and quantity diminishes there is increasing reliance on groundwater to buffer water demands of growing populations. Today in many arid regions around the world aquifer pumping rates far exceed recharge rates. Often the groundwater is nonrenewable, or thousands of years old. Despite the known hydrologic...

  • Deep desulfurization of diesel fuel using a single phase photochemical microreactor

    Creator:
    Jones, Jacob Aaron
    Abstract:
    There is an urgent need to lower the concentration of sulfur in diesel fuels. Growing concern over environmental effects caused by burning sulfur-containing diesel has led the world to higher standards in fuel refinement. Because of these lower standards, many techniques have been researched to remove sulfur containing compounds or...

  • Ecological thresholds, climate extremes, and tree species' distributions across the Pacific coastal United States

    Creator:
    Lintz, Heather E.
    Abstract:
    Species' distributions across the landscape are perhaps the least understood yet most conspicuous features of life on earth. Ecologists have long studied species' distributions; yet, many questions remain about why species occur where they do. Such questions persist largely because species' distributions are complex systems with challenging properties like non-linearity,...

  • The effects of enhanced expression of the GluN2B (NR2B) subunit of the N-methyl-D-aspartate (NMDA) receptor on memory in aged animals

    Creator:
    Brim, Brenna L.
    Abstract:
    As the aging population continues to grow worldwide, age-related complications are becoming more apparent within the aging population. One of the first age-related complications to become apparent is age-associated memory impairment and it can make the elderly more dependent on caregivers early on. The N-methyl-D-aspartate (NMDA) receptor is important to...

  • Fruit quality evaluation of strawberries (Fragaria ananassa) grown in California and Oregon

    Creator:
    Jetti, Rajesh R.
    Abstract:
    Five genotypes from California (Ventana, Caniarosa, San Miguel, 13G97, and Venice) and Oregon (Totem, Puget Reliance, Puget Summer, Hood and Independence) were evaluated for quality. The volatile compounds were analyzed using head space solid phase micro extraction-gas chromatography-flame ionization detection (GGFID) and gas chromatography-mass spectrometry (GC-MS). Odor activity values of...
