Heats of immersion were obtained for four different organophilic
clay complexes in a series of normal alcohol-heptane mixtures
with alcohols of increasing chain length. The immersion calorimeter
employed was the Dewar type with a sensitivity of approximately
5 x 10⁻⁵°C.
Gel volumes were determined for two of the clay complexes...
This dissertation consists of a set of three manuscripts exploring features of effective professional development (PD) for science teacher educators. Literature about context-specific PD for science teacher educators is sparse. The first manuscript, a literature review, outlines theoretical lenses through which PD can be understood, the features of effective PD,...
Prior research has noted the changing demographics of higher education since the Civil Rights Movement and the expanded need for multicultural education. Armando Hernandez Morales (2003) wrote that, “A multiculturally competent person is aware of and knowledgeable about cultural differences, their own cultural identity, and the history and contemporary struggles...
Douglas-fir (Pseudotsuga menziesii) is a widely distributed, ecologically important, and commercially valuable tree species in North America. However, climate change is expected to adversely impact Douglas-fir trees, and assisted migration may become necessary to lessen the effects of climate change. Because drought stress is one of the projected effects of...
As reverse transfer students become a larger part of community college enrollments, it is important to better understand the underlying causes of this nontraditional population’s emergence in the traditional community college system. This quantitative descriptive study found that approximately nine percent of the student body enrolled at Rogue Community College...
During the early fall of 1998, I made contact with Therese Graf Tanalski
when I was searching for family members of deceased Hall of Fame
members. Therese grew up in Corvallis, attended OSU, and married a 1944
CE graduate, Theodore T. Tanalski.
During my conversations and correspondence with Mrs. Tanalski...
Electron microscopic, histochemical and thin-layer chromatographic
techniques have been used to study some cytological changes
associated with seasonal lipid deposition in the liver of Ascaphus.
Histochemical and chromatographic information has shown that unsaturated triglycerides occur in great quantities in the liver of pre-ovulatory females and may serve as a solvent...
