Chloroplast DNA (cpDNA) variability and phylogeny were
studied via analysis of restriction site mutations and DNA
sequencing in a complex of three closely related species of
pines: Pinus radiata D. Don, P. attenuata Lemm., and
muricata D. Don. Genomic DNA from 384 trees representing
20 populations in the complex were...
This study uses an anthropological perspective
to discuss the cultural differences between Chinese
and Americans in business contexts. Through an
analysis of case studies related by businesspersons
involved in Sino-US trade, and by an analysis of
literature on the subject, it describes how cultural
differences contribute to the problems and...
A method for separation and characterization of individual anthocyanins was
developed. High Performance Liquid Chromatography (HPLC) with a polymer based
reversed-phase column was used to separate the pigments while on-line Photodiode
Array Detection (PDA) was employed to record the UV and Visible spectrum of the
individual peaks. Spectral information obtained...
The demand for the development of sustainable energy is an all time high as we burn through limited fossil fuel reserves and as environmental concerns rise every year. Renewable energy sources such as wind and solar power have limitations due to inconsistent power supply that cannot meet the regular needs...
In spite of the lack of accurate information about the
treatability of western wood species with waterborne wood
preservatives, consumption of these products continues to
increase. Western wood species, notably Douglas-fir, are
notoriously difficult to treat with waterborne systems, yet
there is relatively little data on the effects of wood...
The reactions of cyclodeca-1, 2, 5, 8-tetraene with mercuric salts
in solvents of varying nucleophilicity are described. Instead of forming
the usual oxymercuration products reported for reactions of olefins
and allenes with mercuric salts, the major products obtained in the
present cases result from the initial electrophilic addition of the...
Piezoelectric materials have been widely used in electromechanical actuators, sensors, and ultrasonic transducers. Among these materials, lead zirconate titanate Pb(Zr[subscript 1‐x]Ti[subscript x])O₃ (PZT) has been primarily investigated due to its excellent piezoelectric properties. However, environmental concerns due to the toxicity of PbO have led to investigations into alternative materials systems....
This algorithm presents the first steps towards a solution for novice database administrators that helps them transform a non-normalized relational database into a database in the third normal form. The algorithm uses relational algebra operations that apply principles from the third normal form. This provides the database administrator with an...
Four bovine adenovirus type 3 isolates, recovered from different areas in Oregon and Washington, were compared antigenically with the original prototype strain which was isolated in England. The fluorescent foci assay method was used to quantitatively establish viral titers. A serum-viral neutralization test was performed with a standard dose of...
