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 purpose of this study was to determine differences in the way a designer designs because of his or her cultural background. For example, would a designer from the US design with the same components of design in mind as someone from another country? The objective was not to explore...
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...
The researcher investigated Chinese older adults’ (defined here as 50 and over) housing needs and evaluated their perceptions on senior cohousing. The main purposes of the project were to understand the basic and long term housing and elderly care demands of older adults; to identify desirable amenities and services in...
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...
Deep learning is now being utilized widely in applications where sensitive data is being used for model training, for example, in health care. In this scenario, any data leakage will cause privacy concerns to whose data records are used to train the model. An attacker can actively cause privacy leakage...
