A light and electron microscope study of Corylus avellana L.
vegetative buds infested with the eriophyoid mites, Cecidiophyopsis
vermiformis Nal. and Phycoptella avellanae Nal., is reported. Descriptions
are given of changes in infested stipule tissue. The
nipple-like proliferations (enations) which arise on the infested
stipule surface are covered by a...
Corn oil (CO) and Sterculic foetida oil (SFO) fed rats were
injected with [9, 10-methylene-¹⁴C]sterculic acid. Less than 1%
of the label was expired as carbon dioxide. The majority of the
label was excreted in the urine as short-chain dicarboxylic acids with
an intact cyclopropane ring. The major metabolites for...
There are a nearly unlimited number of situations in which the
status of time-varying processes must be updated. The monitoring of
these processes usually occurs at periodic intervals. Whether the
monitoring is performed by man or machine, a decision must be made
regarding the frequency of these activities, that is,...
This paper continues exploration in the area of
programming for parallel computers. The appendix to the
paper contains an extensive survey of the literature related
to parallel computers and parallel programming techniques.
The paper itself presents a new approach to solving
the Laplace equation on a. parallel computer. A new...
This thesis develops a model for locating field offices for the
Motor Vehicles Division of Oregon. The locations are determined by
minimizing the total cost to the Public. This is reasonable because
the Public finances the operation and the opening of the offices
through tax dollars, and it bears the...
Tuberous sclerosis is a serious heritable human disorder
that involves many organ systems. It was first recognized as a
disease entity over a century ago. Its mode of transmission in
familial cases has been fairly well established to be that of a single
gene locus autosomal dominant trait. However, the...
Many centers of population in the Pacific Northwest are dependent
upon employment in the forest based industries. Mary of these
timber dependent communities look to the public forests for their raw
wood requirements. In some localities the installed capacity has outstripped
the local wood supply. This necessitates reaching into other...
The purpose of this study was to compare military
dependent and civilian students with respect to academic
aptitude and the number of problems they perceive in several
areas of their personal lives. It also included a
survey of participation in extracurricular activities in
school and in activity participation in their...
The response of three hardwoods from Ghana and a hardwood and
three softwoods from the United States to liquid and gas-phase impregnation
was investigated. Impregnation with liquids included a sink-float
test in a water-glycerine solution and pressure treatment with a copper
sulphate solution and creosote under identical treating conditions.
Flow...
A study was conducted to determine the heat transfer characteristics
of pin finned heat sinks in natural convection. Three pin
diameters were studied: 0.238 cm, 0.318 cm and 0.396 cm. The pins
were attached to the base in two arrangements, triangular and
rectangular, forming a horizontal array. Pin spacing was...
Two standardized land classification systems designed for use
with remote sensor data were studied comparatively. One of tile
classification systems is proposed for review and testing in U. S. 0.S.
Circular 671 (Legend I) (Anderson et al., 1972); the other is a hierarchial
legend system in use since 1968 (Legend...
Forced vital capacity lung expiration examinations of nonsmoking
and cigarette-smoking male sample populations were compared to
determine if the 75 to 85 percent segment was a more sensitive test
of early lung dysfunction. The nonsmoking population was composed
of 240 men who were tested for values of forced vital capacity...
When selecting an approximate integration technique for use in
a digital differential analyzer, such factors as cost, parts count,
power dissipation and solution accuracy must be considered. This
paper considers the application of the classical rectangular and
trapezoidal integration techniques and a new two cycle method of
integration, all implemented...
This study seeks to estimate and compare tax burdens for hypothetical
families assumed to reside in each of the eleven contiguous
Western states--Arizona, California, Colorado, Idaho, Montana,
Nevada, New Mexico, Oregon, Utah, Washington, and Wyoming. The
estimates are made for a wide range of incomes--from $3,500 to
$50,000--in each state....
Esophageal fistulation, stomach content analysis, fecal analysis,
and ocular-estimate-by-plot are four of the most publicized methods
of determining the diets of large herbivores. The principal objective
of this study was to compare the relative values of each of these
methods based upon information collected from bi-fistulated (esophageal
and rumen) sheep...
This paper compares three classes of algorithms for finding
Hamiltonian circuits in graphs. Two of the classes are exhaustive
search procedures and this study finds them to have an exponential
dependence on the size of the graph. The third class of algorithms,
based on Warnsdorff's rule, is found to be...
