Stagnation point heat transfer in a gas undergoing relaxation of its
internal energy is examined by solution of the equations of motion
using the two temperature approach of Wang Chang and Uhlenbeck.
The results are presented in parametric form and show that relaxation effects produce an adiabatic wall temperature above...
Heat transfer measurements have been made from a long (L/D = 15)
horizontal cylinder in water parallel to a heated vertical wall. The
cylinder and wall boundary conditions were isothermal, and they were
maintained at equal temperatures. The investigation covered Rayleigh
numbers based on cylinder diameter from 400,000 to 10,000,000....
Investment casting has been an important form of metal casting
for many years, but little is understood about the fluid flows that
occur during mold filling. A key to quality castings is the
understanding and control of the fluid flows that are present when the
mold is filled with molten...
Centrifugal casting has been a successful
technique for quickly filling molds, but little is
understood about the fluid flow characteristics that occur
during filling. The understanding of these flow
characteristics and the application of this knowledge
should improve the quality of metal parts cast by this
process. The subject of...
An experimental investigation has been performed to determine the
forced convection heat transfer due to three-dimensional air flow over
a flat plate as a function of angle of attack and free stream velocity.
The experimental method employed a transient thermal technique and
placed the convecting surface next to the exhaust...
An experimental study has been made of the local natural convective
heat transfer coefficient around the circumference of a heated
horizontal cylinder oscillating vertically in water. The heat transfer
surface consisted of a 1 3/8-inch diameter cylinder with a small test
section imbedded in its surface. This enabled data to...
Liquid cooled, laminar microchannel heat sinks were
earlier proposed by Tuckerman for cooling high heat
generating integrated circuits and high power microwave
generation systems using photoconductive switches. A
method of computationally analyzing the heat sinks is
presented which produces the desired temperature and
velocity distributions within the heat sinks. The...
The Boleyn home located in Portland Oregon (latitude 45°) is evaluated based on monitoring data taken from 1977 to 1982. The Boleyn home is a two-story (plus basement) frame home. It takes benefit of passive solar gains and is equipped with an active solar system. The active solar system consists...
The purpose of this study was to evaluate the impact sediment has on the survival of
bacteria in a typical rangeland stream. This information is an important component in
determining a time integrated prediction of bacterial numbers in the stream sediment and
overlying water. Bacterial survival in stream is a...
A PC based on-line advanced plant simulator (OLAPS)
for high quality simulations of Portland General
Electric's Trojan Nuclear Facility is presented. OLAPS
is designed to simulate the thermal-hydraulics of the
primary system including core, steam generators, pumps,
piping and pressurizer. The simulations are based on a
five equation model that...
Convection heat transfer was experimentally investigated
for two different geometries. One case had three horizontal
cylinders in a vertical plane placed between two vertical walls.
The second case had three horizontal cylinders in a vertical plane
with only one vertical wall. Several different cylinder center-tocenter
spacings were investigated. The wall...
A biosystematic investigation was undertaken in 15
species and three subspecies of the genus Aster, in western
North America. Previous studies had been based entirely on
external morphological features, and it was believed that
much could be learned about the natural affinities of the
taxa by exploring their cytological and...
Research Objective: Nearly 60 million people in the United States reside in a rural area. Residents in rural areas have higher rates of chronic disease, risky health behaviors, disability, infant mortality, and age-adjusted mortality than their urban counterparts. Health insurance and access to care mitigate those risks, in part because...
The echinoderm axial organ is located centrally, at the meeting point of the
animals' "circulatory" systems. This, and its unusual histology, have prompted
the implication of a number of different functions for the organ, including
circulation, excretion and host defense. None of these have been definitively
proven. Claims that starfish...
Rats were given single i.p. injections of BCNU to
investigate changes in hepatic cytochrome P-450 content and
specific activity in male rats. Microsomal P-450 levels
were unchanged from 6 hours to 7 days after BCNU treatment
but by day 21 they had decreased 45%. Ethylmorphine N-demethylase
activity (nm product x...
Previous investigation showed that 20 mg/kg BCNU
caused inhibition of sulfobromophthalein (BSP) excretion
and inhibited bile salt independent bile flow (BSIF) in
rats by 48 h after treatment (Hoyt, 1984).
The present investigation demonstrated that BCNU
inhibited the canalicular step in the excretion of BSP.
This was indicated by the...
Male Sprague Dawley rats received a single intraperitoneal dose
of BCNU in experiments designed to measure biochemical changes associated with the pulmonary toxicity described for this agent. Changes in
serum and lung lavage angiotensin converting enzyme (ACE) activity
were measured to detect changes in pulmonary endothelial cell integrity. Alpha-1-proteinase inhibitor...
The entire human population is chronically exposed to various
contaminants, including lead and chlorinated hydrocarbon pesticides.
Studies were undertaken to assess the effects of chronic exposure to
lead on the toxicities of two such pesticides, lindane and dieldrin.
Mice were given lead as the acetate in drinking water, at levels...
The purpose of this study was to give a fifty-nine year historical overview of the development of the state female juvenile institution, Hillcrest School of Oregon. The material covered in the study included state laws which had direct effect upon the programs at the school; the philosophies and goals of...

The purpose of this study was twofold; first, to identify the
values held by Oregon State University students, and second, to
determine if the values of OSU students are different from samples
previously surveyed. A further purpose of the study was to
develop baseline data on a cross-section of the...
Invasive plant species are expanding and transforming vegetative communities across Oregon and throughout the United States. Over the past three decades remote sensing, geographic information system (GIS), and Global Positioning System (GPS) technologies have been integrated to detect and map the distribution of noxious rangeland plants. This study developed low-cost...

The Walla Walla Subbasin (WWSB) in Oregon is underlain by formations of the extensive Columbia River Basalt Group (CRBG) which have been deformed by post-Miocene folding and faulting. Extensive irrigation with groundwater from these basalt groups, as well as sedimentary aquifers and surface water diversions from the Walla Walla River,...

Oregon Biography Index is intended to serve primarily as a starting point in locating biographies of Oregonians. We have indexed 47 historical volumes which are either entirely devoted to biographies or have large self-contained biographical sections. The profiles in the books vary widely in accuracy and detail. Birth dates of...

Mycobacterium abscessus (MAB) is an opportunistic pathogen responsible for infections in immunocompromised or immunosuppressed patients. Even with long-term treatment with multiple antibiotics, MAB pulmonary infections have high rates of treatment failure. Within the host, MAB is phagocytosed by key innate immune cells macrophages. The TLR2 and TLR4 are two critical...
The education (particularly graduate education) of Americans
who were active in astronomical research between 1876 and 1941
is assessed for its effectiveness in preparing the astronomers for
careers in research. This period contains three dynamic changes:
the growth of American astronomy in becoming the world's leading
community of astronomers, the...
