In these tests, phenolic constituents from bark of Shasta red fir were found ineffective as stiffening agents for corrugating medium. Other means of application, however, may be effective.
Gum from inner bark of Shasta red fir was not so effective as a beater additive as was locust bean gum, but...
A microscopic study was conducted on specific gravity wafers taken from standard tensile strength specimens of young growth Douglas-fir. Samples were studied to determine the effect of variables such as percent summerwood, fiber length and fibril angle on tensile strength of Douglas-fir. The sample specimens were picked so effects of...
Six, recent clear cut areas were selected in the Douglas-fir
zone of the Western Cascade Range of Oregon to determine the
environmental and nutritional effects that snowbrush has on the establishment
and growth of Douglas-fir seedlings.
One thousand eighty milacre sample plots on the six clear cuts
were used to...
One of the most important challenges facing foresters is the
development of a raw material measurement system designed to give
a complete inventory of log volume and to assist in planning the complete
management of log production. This paper introduces a concept
of production analysis in terms of solid fiber...
The foraminiferal population of Yaquina Bay was investigated
to attempt a correlation of seasonal changes in the hydrography with
observed changes in the faunal distribution patterns. The results
are based on data from two spatial surveys conducted in July 1966,
and late February and March, 1967.
The hydrography of Yaquina...
Periodic signals hidden in noise may be detected by using
correlation techniques This thesis presents a study of how
correlation is approximated statistically, and carried out electronically.
The ability to detect periodic signals in noise, using correlation,
is justified mathematically in the first portion of the thesis.
The discussion is...
