  • Chemistry of phenolic stains in Douglas-fir sapwood

    Creator:
    Song, Hong-keun
    Abstract:
    Dihydroquercetin [(2,3-trans)-3,3',4',5,7-pentahydroxyflavanonol] was shown to be the precursor to the phenolic stains that often develop in Douglas-fir [Pseudotsuga menziesii (Mirb.) Franco] sapwood. Douglas-fir sapwood was extracted with methanol and the methanol solubles were fractionated by solvent partition, thin-layer chromatography, silica-gel column chromatography, and Sephadex gelpermeation chromatography. Tyrosinase, a commercially available...

  • Building brand equity for unfamiliar Asian brands' entry into global markets

    Creator:
    Song, Sarah Sungsook
    Abstract:
    The purpose of this study is to fill a critical gap in brand equity literature by proposing and empirically testing a brand equity process model for unfamiliar Asian brands. Cue utilization theory (Easterbrook, 1959) and impression formation theory (Asch, 1946) were integrated to explain how extrinsic and intrinsic cues shown...

  • The genetic dissection of the fruitless gene's functions during embryogenesis in Drosophila melanogaster

    Creator:
    Song, Ho-Juhn
    Abstract:
    The fruitless (fru) gene in Drosophila melanogaster is a multifunctional gene having sex-specific functions in the regulation of male sexual behavior and sex-nonspecific functions affecting adult viability and external morphology. While much attention has focused on fru's sex-specific roles, little is known about its sex-nonspecific functions. The embryonic central nervous...

  • Advanced Mass Spectrometry Techniques for Characterizations of Proteome and Lipidome Profiles of Osteosarcoma Cells

    Creator:
    Song, Zifeng
    Abstract:
    Mass Spectrometry has emerged as an analytical core technique in omics sciences, in particularly mass spectrometry has advanced the fields of proteomics, metabolomics and lipidomics in recent years. Mass spectrometric techniques have enabled the characterization and determination of abundance levels of a wide range of biomolecules at molecular and system-wide...

  • Emergent Properties of Animal Social Networks: Five Stories in Five Systems

    Creator:
    Devan-Song, E. Anne
    Abstract:
    Animals aggregate and interact in nonuniform and nonrandom patterns, which lead to group level characteristics that have important evolutionary and ecological consequences. Network analysis provides a useful conceptual framework for linking animal interactions at all scales from dyads to communities, to populations and ecosystems. Despite exciting theoretical and applied advances...

  • Pushing the limits of graphite : the potential beyond conventional applications in aqueous dual-ion batteries

    Creator:
    Kim, Keun-il
    Abstract:
    The increase in the demand for energy is estimated to be 28 TW by a year of 2050, which is twice of the energy produced in 2010, in response to the unprecedented growth of the global population. Current energy market is heavily relying on the fossil fuel, which brings the...

  • Consider the community : developing predictive linkages between community structure and performance in microbial fuel cells

    Creator:
    Lesnik, Keaton Larson
    Abstract:
    The complex, dynamic nature of microbial communities in both natural and engineered environments complicates the work of scientists and engineers who wish to channel microbial interactions for societal good. The successful management of these communities towards engineering goals is dependent on developing predictive linkages between community structure and functional outputs....

  • Electrical Conductivity in Mixed-Species Biofilms for Enhancing Energy Generation in Anaerobic Microbial Systems

    Creator:
    Li, Cheng
    Abstract:
    Further enhancement of energy generation is desired for practical application of anaerobic microbial systems such as microbial fuel cells (MFC) and anaerobic digesters (AD). A possible approach is to enhance the ability of microbial communities to transfer electron extracellularly in the form of electrical current. Critical to perform direct extracellular...

  • Enhancing Hydrogen Production using Single Chamber Microbial Electrolysis Cells by Tackling Hydrogen Scavengers

    Creator:
    Wang, Luguang
    Abstract:
    Biological hydrogen production from renewable feedstocks was reckoned as a promising method for sustainable energy production. Bioelectrochemical hydrogen production using microbial electrolysis cells (MECs) demonstrated superiorities over the conventional methods for hydrogen production. The introduction of the membrane-less single chamber design further improved the feasibility of MECs for practical application,...

  • Cathode development and reactor design for scaling-up microbial fuel cells

    Creator:
    Janicek, Anthony M.
    Abstract:
    Developing new wastewater treatment technologies which will off-set the high-energy cost associated with treatment is necessary to maintain both water and energy security. Microbial fuel cell technology represents one such option. However, there are still many obstacles to overcome before practical application of this technology can be realized. Improving cathode...
