The purpose of this paper is to discuss some of the theory of Boolean matrices and apply this theory to construct contact networks by using algebraic methods.
The first section of this paper (Chapter I to III) describes Boolean algebra and its properties, the theory of Boolean matrices, and the...
Stem form development of trees in response to wind has been established in the literature to be a response to stem sway induced by the wind. The response is manifested in modifications to height and diameter growth which strengthen the stem against wind stresses. Experiments in the literature show that...
Surface and subsurface data are combined to determine the structure of the western half of the Simi fault system in the Las Posas and Camarillo Hills area. Cretaceous to Eocene sedimentary rocks, present only in the subsurface, are overlain by late Eocene to early Miocene nonmarine stata (Sespe Formation) and...
The Pennsylvanian rocks in south-central Idaho and adjacent areas consist of three main facies: a platform facies, a shelf facies, and a marginal basin facies. The platform facies is represented by the Amsden, Quadrant, and Tensleep Formations, in southwestern Montana and western Wyoming, and contain Middle and probably Lower Pennsylvanian...
The purpose of this study was to determine the nature and amountof genetic variation and possible associations between winterhardinessand earliness in winter x spring wheat crosses.Four winter wheat cultivars selected for differences in earlinessand winterhardiness were crossed with a nonhardy, day length insensitivespring wheat cultivar. The following year, experiments containing...
Copper deficiency and Mo-induced Cu deficiency are nutrition
problems of ruminant livestock in the Burns and Klamath Falls area
of Oregon. Chemical analysis of plant and soil samples was used to
survey Cu and Mo levels in forage in these areas. The objectives
were to assess the possibility of animal...
Field studies designed to study residual effects from fertilizer
molybdenum were initiated in September 1971 on established grass-clover
pastures at ten sites in Western Oregon. Treatments were 0.0
and 1.12 kg molybdenum /ha on plots receiving 0-35-0-20S fertilizer (elemental sulfur-S) and 0.0, 0.56, 1.12 and 2.24 kg molybdenum /ha on...
During the Spring of 1969, 47 surface soil samples (0 to 15 cm)
as well as foliage samples of subterranean clover were collected from
32 selected western Oregon pastures, in an effort to determine their
molybdenum status and to evaluate the use of anion exchange resin
method as a means...
This thesis presents an economic analysis for a proposed toll
road which is to separate different types of traffic such as pedestrians,
slow speed vehicles and high speed motor vehicles, and to
divert through traffic from the local roads. The use of a toll road
usually provides significant savings in...
The genus Coenonycha contains 30 described species of small to
medium sized scarabs. They are found in the arid and semi-arid
regions of western United States and northern Baja California. The
adults feed at night on several genera of xerophylous plants.
An examination of the male genitalia of the 19...
The purpose of this thesis was (1) to determine a dietary regimen which would produce the greatest incidence of cardiac calcification in the cotton rat and (2) to determine the fatty acid composition of heart tissue.
Maximum incidence of cardiac calcification occurred from feeding torula yeast ration supplemented with 0.5%...
The reproductive characteristics of the mountain cottontail
rabbit, Sylvilagus nuttalli (Bachman), were investigated from 269
specimens collected in central Oregon between 28 May 1968 and
28 August 1969.
Male rabbits were in breeding condition between mid-February
and 3 July 1969. Nearly 77% of the females bore four litters between
7...
A constant temperature anemometer, utilizing quartz coated hot
film probes, was used to measure velocities from .1 to 5 cm/sec.
The effects on anemometer performance due to time, reimmersion,
and metallic sensor coatings were examinated by repeated calibrations
of the probes. Contrary to previous published results, calibration
change due to...
The thesis area includes 54 square miles of the southeastern
Cuddy Mountains in west-central Idaho. The oldest rocks within the
area are plutonic phases of the Jurassic Cuddy Mountain complex.
These and Cretaceous (?) intrusive and associated (?) extrusive rocks
and nearby Triassic to Early Jurassic metasedimentary and metavolcanic
rocks...
There are six types of Cl. botulinum (Types A, B, C, D, E,
and F). The differentiation between these types is based upon the
antigenic structure of the toxin. Many strains of these various types
have been isolated. In addition, a number of nontoxigenic "type Elike"
strains have come to...
The thesis area includes 44 square miles of the Centennial
Range in Beaverhead County, Montana, and Clark County, Idaho.
The rocks exposed in the area range in age from Precambrian
to Recent and have been divided into 23 mapped units. Pre-Belt
metamorphic basement rocks are overlain unconformably by 3,433
feet...
This programmed text covers the basic elements of the theory
of modulation. It is by no means a comprehensive reference to
modulation topics. The text is designed to introduce the student to
modulation in general terms. After successful completion of this
text, the student should be able to advance to...
A study was conducted to determine the quantity and character
of substances leached from logs floating in water, and the rate of
leaching of these substances. The species of wood studied were Douglas
fir and ponderosa pine. The research was carried out in a controlled
laboratory environment with log sections...
A prototype deep ocean nuclear moisture meter was developed
based on the detection of epithermal neutrons backscattered from
marine sediment molecules. Development consisted of choosing a
source, a detector, containment materials, and associated counting
equipment, followed by the construction and calibration of the probe.
Thermal neutron response of the probe...
