Time is the educational resource educators most desire, but which is
in shortest supply. Educators cannot add more days to the 12-month
calendar year, or minutes to the day. Whatever control is to be had over the
calendar and clock rests in the way time is managed by those in...
A population of Nuttall's cottontails (Sylvilagus nuttallii) in Deschutes County, Oregon, decreased fromm 166 individuals in August 1978 to 76 individuals in August 1979. Survival rates of four annual litter groups in 1978 were 0.74, 0.35, 0.72, and 0.93; survival rates for the same litter groups, respectively, in 1979 were...
Three-dimensional laser scanning has revolutionized spatial data acquisition and can be completed from a variety of platforms including airborne (ALS), mobile (MLS), and static terrestrial (TLS) laser scanning. MLS is a rapidly evolving technology that provides increases in efficiency and safety over static TLS, while still providing similar levels of...
This thesis describes a project to produce controlled release ketoprofen beads for capsules, both at Oregon State University and in an industrial scale-up operation, that are bioequivalent to the commercial product Oruvail. A bead formulation was produced by layering drug and binders in water onto nonpareil sugar seeds in a...
The development of a geographic information system
(GIS) requires the development of large databases of
spatially related information. Scale, resolution and the
classification of thematic data can vary considerably in
terms of the level of detail at which the data are compiled
and converted to machine readable form. The level...
The principles of mobility are applied to the forest setting to
simulate the movement of logs with a rubber tired-skidder. A computer
program was written to perform the analysis . Vehicle-terrain and logterrain
interactions are the resistances which must be overcome by
the available vehicle power. The rate at which...
Strategic planning for forests subjected to multiple uses is important for management that sustains and balances these many uses. In the wildland urban interface where forests are in the backyards of members of the public who avidly recreate in them, it is also important to include the community in the...
Landslides are an insidious natural hazard, which can result in significant damage to public infrastructure. Limited monitoring tools are available, particularly tools suitable for use in forested environments. These tools often only allow a few locations across the slide to be monitored. Terrestrial Laser Scanning (TLS) shows promise as a...
The focus of this research is to develop a personal computer based simulation model of the mechanized logging process, from felling until the log arrives at the sawmill. The SLAM II simulation language is used for modeling, and the main emphasis is on the overall performance of this system, and...
Straw wattles are common erosion control devices used to trap sediment. This
thesis studies the relationship of straw wattles on slope stability through a case study
demonstrating their use on steep slopes (1.5H:1V) for the US20 highway realignment
project. Several surficial slope failures have occurred on these fill slopes, often...
