Nearly 9,000 feet of Cretaceous mudstones, shales, sandstone,
and conglomerates are exposed along the northeast-trending Mitchell
anticline of central Oregon, These rocks are divided into two formations
on the basis of criteria developed in this investigation. The
lower formation, hereby designated the Meyers Formation, is 4,716
feet thick at its...
The thesis area covers 165 square miles including the greater
part of the northeastern quarter of the Mitchell quadrangle in north-central Oregon. The three stratigraphic units exposed in the area
consist of a variety of Tertiary volcanic rocks including the Clarno
Formation, the John Day Formation, and the Columbia River...
In the area surrounding Clarno, Oregon, pre-Cretaceous metamorphics, Cretaceous marine sediments, and a varied assemblage of Tertiary volcanic rocks are known. The oldest exposures are of an homogeneously fine-grained, mildly metamorphosed, limy shale to which the term "Muddy Ranch phyllite" is applied. Non-metamorphosed, Cretaceous marine shales and graywackes, approximately 1500...
The mechanical properties of materials at cryogenic temperatures
have been the subject of increasing interest during the past few
years, although very little actual materials testing has been done at
extremely low temperatures because of the high cost and low heat of
vaporaization of liquid helium. Recently, the Department of...
Quercetin (3, 3', 4', 5, 7-pentahydroxyflavone) reacts with hexavalent
molybdenum, tungsten and chromium to form chelates soluble
in an ethanol-water medium. This color reaction has been investigated
with a view to its possible application in the spectrophotometric
determination of trace amounts of these metals.
In the development of the method,...
This investigation has as its purpose: (1) to identify present
student personnel practices in evening community college programs,
(2) to identify student personnel practices considered "desirable" or
"undesirable" in evening community college programs, and (3) to
develop student personnel service guidelines for an evening community
college program.
