Extractable forms of Al and Fe were studied in five soils from
the Coast Range, and in two soils from the Willamette Valley in
Oregon.
Exchangeable Al was determined in a way which permitted a
comparison of three different methods for its determination. Values
for exchangeable Al obtained by the...
The rapid accumulation of plastic waste in landfill, waterways and oceans is becoming a critical problem, one that current recycling technologies are not capable of solving. Recent proposed approaches in the depolymerization of waste plastics employ an Olefin-Intermediate Process (OIP), where feedstocks like polyolefin plastics are ‘activated,’ producing an olefin...
The influence of pH (titration method) and of salt concentration
and drying (drying method) upon the formation of synthetic AI, Fe,
and Mg interlayers in montmorillonite and vermiculite was investigated.
Interlayer formation was evaluated by X-ray diffraction
measurements of basal spacings using a natural chlorite for comparison.
The titration method...
Mineralogical analysis of 3 upland soil profiles over Tyee parent
rock from the Alsea Basin Area, Oregon showed clear differences
among the 4 soil series represented. Soils from the area of higher
precipitation (over 80 inches, approximately) had no montmorillonite,
lower base saturation and cation exchange capacity, but no lower...
The purpose of this descriptive research was twofold: 1) to
determine the expressed concerns, feelings, and needs of a selected
group of expectant fathers; and 2) to categorize those expressed
concerns, feelings, and needs into broad areas and to develop a
priority listing of those items as a basis for...
Purpose: The major purpose of this study was to determine the readability of selected patient education materials for older adults using the cloze procedure as a criterion. Actual cloze test scores from three selected passages on hypertension were compared with the Coleman readability scores on those same passages. Age and...
This study, conducted with the cooperation of the Oregon Comprehensive
Health Planning Agency, Salem, had a threefold purpose:
(1) to identify the role of the physician's assistant (PA) in Oregon,
(2) to provide substantive data for recommendations regarding changes
in PA licensure, and (3) to provide information which may be...
Purpose
The primary purpose of this study was the development of an
instrument for identifying competencies required by nurse-supervisors
in small general hospitals. Secondary objectives of this study were:
(1) to demonstrate the applicability of the instrument, and (2) to
determine similarities and differences in the perceptions of hospital
administrators,...
