Modern science was produced by a Christian society,
and although science has had an effect on Christianity, it
could not itself remain unaffected. In the second half of
the nineteenth century, the subject of evolution was as
much a religious as a scientific issue. The battle line
was drawn and...
There were two viable theories of generation, preformation
and epigenesis, existing in the Seventeenth and
Eighteenth Centuries. Due to their irreconcilable nature,
they were often at loggerheads during this time interval.
The status of these generation theories can be effectively
understood in terms of Thomas Kuhn's conception of preparadigm
science....
The Carnegie Ridge is a linear, aseismic, submarine ridge
lying between the Galapagos Islands and the coast of South America.
A 2300 meter deep saddle near 86°W. longitude divides the ridge into
western and eastern segments. Surface ship, near bottom, and grain
size studies from the saddle have been used...
The topic of summability methods has been studied by many
although the name of G. H. Hardy and his classical work "Divergent
Series" is best known. Almost all of the early work was done using
single sequences or series. In the past 30 years research has been
done extending some...
The existence of eigenvalues is shown for certain types of
integral equations with continuous kernels, the proofs utilizing some
basic results of collectively compact operator approximation theory.
The development of the energy crisis has caused the
use of depletable energy resources to be monitored quite
closely in the United States. Within the agricultural
sector, irrigation is a large user of energy, with the
potential of using many times more energy than all other
agricultural field operations. A...
Purpose of the Study
The purpose of the study was to determine whether
there were significant differences in students' achievement
and attitudes as a result of two different instructional
strategies utilized in a vocational graphic arts
program. In order to accomplish this, the following
procedures were considered.
Procedures
This comparative...
The objectives of this investigation were to examine the changes in vegetation resulting from application of herbicides, and to study the effects of these vegetative changes on the abundance and composition of small-mammal populations, and on deer usage of treated and untreated plots. Three areas in western Oregon were selected...
This study was conducted by the School of Forestry at Oregon State University to provide some of the information needed by the Oregon Board of Forestry to develop a forestry program for Oregon. The study makes three contributions: One, a data base that provides an up-to-date timber inventory and information...
The objective of this study was to determine whether wild populations of trout in the North Fork of the Middle Fork of the Willamette River can support a catch rate of 0.3-0.5 trout per hour at current levels of effort and to predict how different size and bag limits would...
Expansive soils in Eugene, Oregon present a problem to
residents, consultants, contractors, and the city government. During
the years 1977 to 1979, the nature and extent of the problem was
identified, including an outline of the local occurrence of expansive
soils and possible engineering solutions to the most often encountered...
Twelve differential agars have been studied in the development
of media to presumptively identify the Salmonella Subgenera
I-IV. Medium No. 7B/A (or Medium No. 7-H₂S Strip) combined
the malonate, dulcitol, lysine decarboxylase and hydrogen sulfide
reactions in one tube. It was designed to be used at the TSI stage
of...
Observed intensity fluctuations in the emission of Starkperturbed
Ly-α and Ly-β radiation from beam-foil formed atomic
hydrogen are compared with theoretical calculations to yield information
on the relative cross sections for creation of a hydrogen atom into
the various l -levels for n = 2 and n = 3. It...
Saccharomyces cerevisiae strain XS-380, a. heteroallelic
diploid strain, carries six genetically analyzed loci on the left arm of
chromosome VII. Nitrosoguanidine (NMG) at low concentrations was
observed to cause allelic recombination (either mitotic recombination
or gene conversion) of the heteroallelic loci with low lethality.
The NMG-inducible heteroallelic system was used...
