Sampling studies were conducted to compare the efficiency of the four officially recommended methods of sampling small seeds: automatic sampling--at two sampling speeds, hand sampling, Nobbe tier sampling, and stick trier sampling. Synthetic lots of orchard-grass, ryegrass, Kentucky bluegrass, and alfalfa seed were prepared containing known numbers of the common...
Acetylbenzoyl reacted with dimethylamine hydrochloride
and benzaldehyde in primary isoamyl alcohol under
reflux conditions to form 1,4-diphenvl-3-butene-1,2-dione,
compound I, which melted at 56-57°C.
Compound I formed a quinoxaline derivative, compound
II, which melted at 152.5-153°C.
Compound I was cleaved by hydrogen peroxide to form
cinnamic acid, compound III, which melted...
Consider a transformation group G operating on a space X
and a G- invariant function f defined on a G- invariant subset of
X. By imposing suitable conditions on X, G, f and A, the
author derives sufficient conditions for extending f invariantly to
the whole space, and thus generalizing...
This study explored the management problems and practices
of 41 Asian graduate students at Oregon State University. The students
were asked to indicate their management problems and
practices of food, clothing, and money, their housing conditions,
their problems in finding recreation and transportation, and their
problems in their academic work...
This study was designed to reveal the outcomes of participation
in science project activities such as Science Fair projects among
ninth grade science students in Multnomah County, Oregon, during
the second half of the 1963-1964 school year.
A stratified sample of five public schools was selected to participate in this...
The purposes of this investigation were: (l) To attempt to
determine how well programs of guidance services were felt to be
functioning in meeting the needs of pupils through an analysis of
guidance services in selected high schools in Oregon, and (2) To
develop recommendations for improving programs of guidance...
The primary objective of this study is to explore the possibilities of two methods to reduce the weight of small commercial timber prior to logging. The two methods studied are injection of cacodylic acid and sour-felling. Treatments were applied in November, 1965 and May, 1966, with final harvest of the...
