Bigleaf maple chips were pulped by the kraft, Magnetite, neutral sulfite semichemical, and refiner groundwood processes. Pulp from each process was refined in a Valley Beater and the handsheet properties of the refined pulp were compared to similar pulps made from other wood species. For the kraft process a different...
Large amounts of plant tissue are used in the production of many
canned, frozen and dried foods. Some of this material is unsatisfactory
in appearance and texture, despite careful processing from high quality
raw materials.
In the present study, the changes induced in soft fruits by controlled
heating and freezing...
The concentrations of iodophor necessary to reduce the activity
of several metabolic enzyme systems 50 percent was used as the
basic approach in attempts to elucidate the mechanism of germicidal
action of iodine. For comparisons, a chlorine-releasing germicide
(Trichlorocide) and a quaternary ammonium compound were also
tested. It was found...
An on-line trace enrichment (TE) system, based on high pressure
liquid chromatogroaphy (HPLC) and flame atomic absorption (AA), has
been developed for trace metal analysis. The sample is pumped through
a column filled with a cation exchange resin which traps metal ions.
The ions are subsequently stripped from the column...
The Purpose of the Study:
The central purpose of this study was to compare the role perceptions
of (A) non-degree vocational teachers recruited from business
and industry, (B) experienced vocationally certified teachers who had
been teaching more than five years, and (C) new-degree vocational
education graduates from Oregon State University....
Prior to November 2010, when The Intertwine Alliance launched the Regional Conservation Strategy (RCS) and Biodiversity Guide (RBG) efforts for the Portland-Vancouver metropolitan region, conservation priorities in the metropolitan region were identified at a broad regional scale that generally excluded urban areas (e.g., state conservation strategies and Willamette Synthesis); were...
