exhibited in varying degrees a...
Grass seed production in Oregon's Willamette Valley traditionally relied on open field burning for straw residue disposal and nutrient recycling. Changes in residue management from open field burning to methods that remove straw coincided with rapidly declining K soil test values. A survey of grass seed fields showed that many...
Gradeability of log trucks is limited by either
vehicle rimpull or ground-tire adhesion. The analysis presented shows that log trucks in current use in the Pacific Northwest are limited by tire-slip gradeability rather than by rimpull. Analytic techniques were used to determine that gradeability is greatest for piggyback and least...
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...

We examine the 0–100 Ma paleoceanographic record retained in pelagic clay from the South Pacific Gyre (SPG) by analyzing 47 major, trace, and rare earth elements in bulk sediment in 206 samples from seven sites drilled during Integrated Ocean Drilling Program Expedition 329. We use multivariate statistical analyses (Q-mode factor analysis...
Dating pelagic clay can be a challenge due to its slow sedimentation rate, post-depositional alteration, and lack of biogenic deposition. Co-based dating techniques have the potential to create age models in pelagic clay under the assumption that the flux of non-detrital Co to the seafloor is spatially and temporally constant,...
Anthocyanin degradation in freeze-dried strawberry puree was studied under various relative humidity conditions at 37°C. Moisture was found to be the determining factor in the rate of pigment degradation. Storage at relative humidities below 11% provided good pigment retention in this low-moisture product. Enzymatic degradation of the anthocyanin pigment did...
This thesis has four main results. First we find a reduction form
for symmetric matrices over fields of characteristic two. This result
parallels the diagonalization theorem for symmetric matrices over
fields of characteristic not two.
Secondly we reduce our reduction form to a canonical form in

large enough for a good separation. This fact was applied...
Methane is the most abundant organic chemical in the
earth's atmosphere. Its abundance in the atmosphere is
increasing with time and has reached levels not seen in recent
geological history. The methane is produced both naturally, and
anthropogenically. One of the sources of anthropogenic methane
is manure from domesticated animals....
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....
