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...

A multipoint environmental temperature recorder is described. Some of the many features that recommend the application of this recorder to field studies are multiple input capability, efficient use of chart
paper, reliability, and low power consumption from batteries. Design considerations and electrical details are provided.
In the Coniferous Forest Biome, many of the understory as well as
dominant plants are evergreen and thus water uptake is a year around
process. The flow of water from the soil through plants to the atmosphere
affects the entire forest ecosystem. As water is evaporated, it absorbs
heat and...
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...
