In an attempt to satisfy an existing need for a small gas
sample pump, a proposed design was analyzed and determined to be
feasible and a design for a prototype model was produced. The
design is of a chemically inert, leak-proof, unlubricated, sliding-vane-
type pump. It is designed to pump...
A program of research has been established at Oregon State
University to study wood residue combustion using an experimental
spreader-stoker combustor. This research was conducted to increase
the understanding of combustion occurring in wood fired boilers.
Using Douglas Fir screened to 3/8-3/4 inches, two 4x4 factorial
experiments were conducted varying...
In response to the growing preference for the small family, this study was carried cut to acquire information about women who expect zero, one, or two children. The purposes of the study were: to identify the cultural and socioeconomic characteristics of these women; and to determine which of these characteristics...
During a 13-month period starting in October of 1976, adult
male rough-skinned newts (Taricha granulosa) were collected periodically
to study seasonal changes in reproductive status. Plasma
androgen concentration, measured by radioimmunoassay, is elevated
during autumn and spring (about 50 ng/ml). Winter and summer levels
are considerably lower (less than 10...

Sulfur-coated urea (SCU) is a slow release nitrogen fertilizer
manufactured by the Tennessee Valley Authority. Urea granules are
sprayed with molten sulfur, then holes in the sulfur coating are sealed
with a layer of wax sealant. The sulfur coatings are mixtures of
amorphous and crystalline allotropes of sulfur. Coating thickness...
