Dwell time low cycle fatigue (DLCF), low cycle fatigue (LCF), and creep tests were performed at ambient temperature on Ti-6Al-2Sn-4Zr-2Mo-0.1Si (Ti-6242Si). Test specimens were solution annealed at various temperatures below the beta transus to control the volume fraction of primary alpha. The influence of the changes in primary alpha phase...
Greenhouse and field grown coffee plants were used to
study the synchronization of flowering and fruiting. The
purpose of these studies was to develop methods of
improving the selective harvesting of mature coffee fruits
by machine. The studies were divided into 4 parts: 1)
Synchronization of flowering, 2) Synchronization of...
The influence of overstory openness on the reproductive
ecology of Pacific yew (Taxus brevifolia Nutt.) was
investigated on 4 sites in western Oregon over 2 years. The
breeding system of T. brevifolia was found to deviate from
pure dioecy under a broad range of canopy and site
conditions. Production of...
The purpose of this investigation was to examine the
literature in education and library science to determine
why standards for education libraries have not been
realized, in the light of the specific criteria for other
areas of teacher education accreditation. Educators and
librarians in favor of strict standards for education...
Two studies on Catherine Creek and Meadow Creek of the Upper Grande Ronde
River basin, quantified several physical and biotic influences on woody riparian community
composition and structure. The Catherine Creek study examined the association of woody
riparian species with elevational and geomorphic gradients. The Meadow Creek study
examined the...
Statistically, travel by air is one of the safest forms of transportation. Yet we
continue to experience aviation tragedies. Do we fully understand flight safety or is
there another way of looking at the problem? In this work a new way of approaching
the question of flight safety is developed,...
Although endothermy is one of the most significant evolutionary developments in the vertebrates, its origins among extinct taxa have traditionally been difficult to determine. Endothermy is primarily an attribute of the "soft anatomy," and its key features, such as complex lungs, elevated blood oxygen carrying capacity and mitochondrial density, do...
