The reactions between sodium nitrite and the polyamines
spermidine and spermine were investigated. When reacted at 80°C
for 1 hr at pH 3.5 with a 1:3 molar ratio of amine groups to sodium
nitrite, five volatile nitrosamines were identified as products in the
nitrosation of spermidine. 3HC1, and two volatile...
This thesis describes the results of a linear stability analysis conducted on a simulated wind-forced ocean front. The ocean surface boundary layer regulates exchanges between the ocean and atmosphere, and the presence of turbulence in the surface layer can greatly impact climate and ocean life. Past research has shown that...

ABSTRACT
This thesis describes the results
The Jetson Artificial Intelligence Tool chain (JAI-TC) is a set of packages, APIs and libraries for Artificial Intelligence applications to be deployed on the NVidia SOC, Jetson TX2. JAI-TC automates the installation of these items allowing for a wider set of users to leverage these technologies. Prior to this, the...
The concept of marketing, with its primary focus on
meeting customer needs, is being adopted by federal agencies
such as the U.S. Forest Service who are in the business of
providing, among other things, recreation opportunities for
their visiting public. Although not a new concept, the
notion of applying marketing...
The sinuous flight behavior of male Douglas-fir tussock
moths, Orgyia pseudotsugata, (McD.), is characterized by
positive anemotaxis and positive chemoklinotaxis and varies
depending on distance from the pheromone source, population
density, and time of day. Visual cues play a minor role
in close-range orientation to a pheromone source, but
males...
Equipment for strip-till planting is under development in wheat-fallow
rotations in the Columbia Basin of Oregon. This involves the
absence of tillage during the fallow season. At planting time, the
strip-till planter creates a narrow band into which the wheat seed is
placed. The area between the rows is undisturbed...
The National Agricultural Statistical Service (NASS) conducts quarterly surveys for estimation of some primary commodities produced on farms and ranches. The commodities often have highly skewed distributions with a few farms producing very large amounts. NASS uses dual sampling frames comprised of the list frame for efficient stratification and the...
A personal computer with a Data Acquisition and
Control Adapter interface has been used to monitor the
power of the Oregon State University TRIGA Reactor, and
from the time behavior of the reactor power the reactivity
has been computed using the point kinetics equations and
displayed on a digital read-out...
The composite FRP rebars research at Oregon State University was initiated in
1993 principally to develop a non-metallic hollow reinforcement. It was recognized that
the tensile properties of such reinforcement are unquestionably superior to steel, but its
performance in concrete could be problematic. The bond between FRP rebars and
concrete...
New technology allows the production of thinner kiln sticks
manufactured of phenolic resin impregnated paper which are both
structurally and economically realistic. This project tested the effects
of kiln stick thicknesses on dry kiln air circulation and on
lumber drying degrade.
Three variables, stick thickness (3/4, 9/16, 7/16 and 1/4...
