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...
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 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...
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...
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...
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...
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....
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...
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,...
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...
