An investigation was conducted to ascertain if certain concepts
of microbial metabolism, derived from studies using simple
soluble substrates, are applicable to the biological assimilation of
complex, partially colloidal suspensions. A mixture containing one
gram of Carnation dry-skim milk is considered to be a complex,
partially colloidal substrate and was...
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...
The energy budget of a pumice desert surface was analyzed under clear skies during early, mid-and late summer periods. The pumice site is in the semi-arid plateau region of Central Oregon at an elevation of about 1500 meters. The flat pumice surface is approximately 250 hectares in extent, and is...

Plants can be identified by means of keys based on plant characteristics, frequently the flower. Keys enable the user to distinguish one species of plant from another. However, a single key to all flowering plants would be so cumbersome it would be impractical to use. Thus plant manuals ordinarily contain...
Pressed and dried plant specimens are useful as teaching aids and reference sources for plant identification, or as decorative material. Select plants to be mounted with care, prepare properly, and accompany by adequate, clearly expressed, written identification data. This publication suggests materials and methods for selecting and preparing plants for...
