This paper describes an inverter design which provides voltage
regulation against variations in both the input voltage and load impedance.
This design modifies the so-called parallel inverter, which
consists of two silicon controlled rectifiers...

This thesis presents and discusses a method for comparing
the neutron flux of some calculational model with the actual
flux of a critical system. Both the theoretical and experimental
aspects of this method are investigated in this report....

Rapamycin was found to increase (11% to 16%) the lifespan of male and female C57BL/6J mice most likely by reducing the
increase in the hazard for mortality (i.e., the rate of aging) term in the Gompertz mortality analysis. To identify the...

Studies were conducted to establish some characters which
could be used, either in the field or in the laboratory, to differentiate
between annual ryegrass (Oregon), Lolium multiflorum Lam. , and
Linn perennial ryegrass, Lolium perenne L....

A method by which barrier heights in potential functions
hindering internal rotation in organic molecules can be obtained solely
from thermal data for the solid phase is studied. The observed
heat capacities are analyzed in terms of contributions...

This study was conducted to investigate the differences of the
profile distribution of free iron and free manganese and the reduction-oxidation changes in soils of the Willamette drainage sequence.
Based on the results of the chemical analyses,...

The possibility of synthesizing 1, 8-naphthyridines by the
Doebner reaction has appeared in many reports. The method involves
the introduction of electron releasing groups in the 6-position of
2-amino pyridine to activate the C-3 position....

The emergence of the three-input majority gate as a practical
element for logical design has demanded a useful method of design
using these elements. In order to facilitate the use of this gate, a
digital computer program is presented to implement...

Gamma irradiation inactivation kinetics were studied using
fifteen organisms naturally contaminating seafoods. Survival curves
for seven Salmonella, three Shigella, two Streptococcus species and
a Staphylococcus, Escherichia and Proteus species...

The Pacific Coast variety of Douglas-fir was investigated.
The samples were tested using both forced and free vibrations. Transverse
vibrations were introduced by excitations on the side of the
samples. Forced vibrations were applied from 5000 to...

Statistical data from breeding experiments suggested that a
reciprocal chromosomal translocation had spontaneously occurred in
a line of S. C. White Leghorn fowl. Approximately 50% of the
embryos from matings between suspected translocation...

This study explored the management problems and practices
of 41 Asian graduate students at Oregon State University. The students
were asked to indicate their management problems and
practices of food, clothing, and money, their housing...

This thesis discusses a method of fast multiplication by parallel
addition of summands. A logical element that performs this parallel
addition is defined, and examples of the element realized with threshold
logic are shown. Relations between the...

Ectomycorrhizal fungi (EmF) form symbioses with trees. These symbioses profoundly influence forest ecology. Certain EmF form specialized profusions of hyphae, known as ectomycorrhizal fungal mats (mats) which are visible to the naked eye, alter...

Nitrogen is one of the major nutrients limiting microbial productivity in the ocean, and as a result, most marine microorganisms
have evolved systems for responding to nitrogen stress. The highly abundant alphaproteobacterium “Candidatus...

BACKGROUND: Basic leucine zipper (bZIP) transcription factors are present exclusively in eukaryotes and constitute
one of the largest and most diverse transcription factor families. The proteins are responsible for central
developmental and...

The computation of symmetric functions can be tedious.
For this reason, the object of this paper is to devise a computer
program so that these symmetric functions can be handled automatically.
The contribution of this investigation is a heuristic...

The purpose of this study was to compare and test the efficiency of the leading kinds of media being used for the isolation and identification
of Clostridium botulinum type E strains, and to develop a
more reliable method and media for the...

A technique is presented for obtaining high resolution root locus plots and
Bode diagrams. This is done by translating the origin of coordinates to the area
of interest by an appropriate change of variable. The method is applicable to
hand...

Forests are major components of the global carbon cycle, providing
substantial feedback to atmospheric greenhouse gas concentrations¹.
Our ability to understand and predict changes in the forest carbon
cycle—particularly net primary productivity...

A programmed unit on diabetes mellitus was written
and tested on three groups of students. These included a
class of licensed practical nurses taking a refresher
course in pharmacology, a class of third year pharmacy
students, and a class of first...

The maximum principle developed by the Russian mathematician,
L.S. Pontryagin is considered to be one of the most significant
contributions to the recent advances in mathematical optimization
techniques.
Unfortunately, most of the published...

A mathematical model of a differential thermal analysis (DTA)
system was formulated so that influence of the various physical parameters
on the DTA peak could be determined. The specific DTA apparatus
simulated had cylindrical sample holes drilled...
