The free convective heat transfer phenomena in air between two
vertical plates 24 by 38 inches spaced 15.895 mm apart, was investigated in this experimental study. One plate was isothermal and, the
other adiabatic.
A quartz fiber anomometer was used for measuring local
velocities in the air between the vertical...
This report presents tables of suspended-sediment data collected from 1956 to 1967 at 10 sites in the Umpqua River basin. Computations based on these data indicate that average annual suspended-sediment yields at these sites range from 137 to 822 tons per square mile.
Because available data for the Umpqua River...
Physical activity recognition using accelerometer data is a rapidly emerging field with many real-world applications. Much of the previous work in this area has assumed that the accelerometer data has already been segmented into pure activities, and the activity recognition task has been to classify these segments. In reality, activity...
Since its discovery in Oregon in 1946, the pear psylla, Psylla pyricola Forster, has become the most serious insect pest of pear. Damage to pear trees include the transmission of pear decline disease which has caused losses of trees, injection of a phytotoxic toxin resulting in tree shock and injury,...
While the need to solve problems of overcapitalization and excess investment in fisheries is now broadly
admitted, very little information exists on the level of capitalization and the structure of capital invested in
the fishing sector. This paper presents the first results of a research program aiming at assessing the...

Premise of research: A distinctive new species of osmundaceous fern, based on a permineralized trunk from
Lower Cretaceous deposits of Haida Gwaii (formerly the Queen Charlotte Islands) off the west coast of mainland
Canada, provides additional data for addressing the Mesozoic diversity and the overall pattern of phylogeny
for osmundaceous...
To best manage Eagle Creek National Fish Hatchery and minimize any negative impacts that the current hatchery program may be having on Endangered Species Act-listed salmonids in the Eagle Creek Basin, I determined if wild fish are being displaced from preferred habitats by hatchery salmonids Oncorhynchus spp. This thesis had...
