This history concerns the scientific contributions of Charles
Babbage (1791-1871) to mathematics, to the invention of calculating
machines, and machine tools, to the development of scientific ideas
through a wide variety of scientific investigations and his involvement
in several different scientific reforms. Babbage considered himself
a philosopher in the broadest...
This bibliography focuses on works that will provide the reader with supplemental resources on the history of ethnic minorities in Oregon. An effort has been made to highlight materials that are particularly appropriate for use in teaching students of various ages. The featured resources address all historical time periods, but...
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...
This research effort examined Traditional Ecological Knowledge (TEK) of Siletz tribal members of the environment they live and/or lived in, and how both Western societal beliefs and land reduction to the initially established reservation location affected and altered how the area TEK has been maintained and passed down. The theory...
Radioactive chromium-51, a waste byproduct from operation
of nuclear reactors at Hanford, Washington, has been followed down
the Columbia River and into the Pacific Ocean. Chemical factors
influencing the partitioning of ⁵¹Cr between solution and sediment
have been considered.
Chromium-5l, in a hexavalent oxyanion when introduced into the
Columbia River,...
Persistence has been identified as an issue at all levels of higher education,
and numerous strategies have been attempted to stem the flow of students who leave
an institution before completing their programs of study. Persistence research
abounds at the community college, four-year college and university levels, but little
research...
E+A galaxies represent an important niche in galaxy evolution as a subset of post-starburst galaxies. Set apart from other post-starburst galaxies by their rapid quenching of star formation, E+As are thought to have started their formation outside a galaxy cluster's center and have fallen inward due to gravity; the star...
Research on the application of soluble, metal chelates for
water tracing using thermal neutron activation analysis for tracer
determination has led to the development of several tracers with
promising solution stabilities (conservative behavior) and determination sensitivities. The solution stabilities of the ethylenediamine
tetraacetic acid (EDTA) and the diethylenetriamine pentaacetic acid...
