Bidirectional reflectance is a fundamental property
used for the analysis of radiative heat transfer. It is a
form of reflectivity in which the spectral and directional
dependencies of both the beam incident on a surface and the
beam reflected from the surface are specified.
A new system has been designed...
Monoclonal antibodies were developed against USDA
challenge strain of infectious laryngotracheitis virus (ILTV).
Indirect immunofluorescence test was used to detect antibodies
in supernatants of hybridomas. Hybridoma cells were developed
by fusing Sp 2/0 myeloma cells with spleen cells obtained from
mice immunized four times with partially purified USDA
challenge strain...
Staphylococcal tenosynovitis and osteomyelitis are world-wide problems of
broilers and broiler breeders caused by staphylococci. Pathogenesis of the disease is
ill defined. Avian heterophils are analogous to mammalian neutrophils but the
granules appear to be different.
The first chemotactic study was done on heterophils from chickens having
natural staphylococcal infection...
During the operation of phase-change ink-jet printers a bubble formation
phenomenon often occurs. These bubbles are detrimental to the operation of
the printer and substantial efforts are made to remove them. The objective of
this research was 1: to develop a fundamental understanding of how bubble or
void formation occurs...
A two-dimensional model for predicting the rate of radiation
heat transfer for the interior of an industrial furnace is described.
The model is two-dimensional due to the assumptions of the heat
source as an infinite radiating plane and the heat sink as rows of
parallel tubes that are both infinite...
This study investigated the laboratory performance of crumb rubber modified
mixtures compared to a standard bituminous mixture using performance based test
procedures. This study was part of an asphalt resurfacing program for the Seattle
Washington area. Laboratory analyses were used to estimate the long term pavement
performance of these mixtures...
Monoclonal antibodies (MCA) produced against infectious
laryngotracheitis virus (ILTV) of chickens reacted in
western blotting experiments with several different ILTV
protein bands in the absence of tunicamycin which inhibits
carbohydrate synthesis. Most of the MCA lost their
reactivity in western blotting experiments when extracts of
tunicamycin-treated ILTV CELC were used,...
Large quantities of unused heavy oil and residual waste products from the petroleum refining industry were deposited in on-site landfills, pits, and lagoons, prior to the promulgation of regulations governing their disposal and technology development that would further utilize and/or recycle these materials.
Contacting petroleum products with sulfuric acid for...
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...
Environmental factors and physical properties of latex modified concrete (LMC)
are hypothesized to contribute to early age cracking in bridge deck overlays. Cracking
permits the ingress of moisture and aggressive solutions into the substrate and may
contribute to other subsequent distresses. Understanding the material properties and
mechanisms involved is necessary...
Heat transfer and fluid mechanical behavior of water
flowing horizontally in vertically-narrow rectangular
channels was studied in this work. Friction factor and
Nusselt number variations were determined experimentally
for four different wall heating conditions, and for aspect
ratios(height to width) of 5, 4, 3, 2, and 1. Wall
heating conditions...
Riparian areas contribute to numerous ecological-maintenance functions and so are
often the focus of protection efforts by land and resource management agencies. The riparian
land-use regulations of one jurisdiction, Lane County, Oregon, are assessed for effectiveness in
protecting ecological functions. Evaluation of the current condition of five elements of riparian...
Since 1983, the Oregon legislature and the Land Conservation
and Development Commission have been attempting to develop a
process whereby secondary resource lands can be identified and
designated. The most recent attempt at developing a secondary
lands model was completed in 1990 and was tested in six Oregon
Counties. Planners...
Increasing wilderness use, and the uneven distribution
of use within wilderness areas, have contributed to management
problems. Problems associated with some heavily visited areas are
in conflict with the intent of the Wilderness Act of 1964. One of
the constraints hindering optimal management has been the decentralized
nature of the...
A Delphi Expert Opinion procedure was used for evaluating Land Evaluation
and Site Assessment (LESA) ratings in Linn County, Oregon. The Delphi procedure uses
an expert panel to answer a set of questions by anonymous responses, controlled
feedback in two or three iterations, and a statistical summary of group responses....
