Timber engineering is currently in the midst of a significant evolution due to the rise of mass timber products, like cross-laminated timber (CLT). Increasing numbers of structural engineers are facing the challenge of designing lateral-force-resisting systems (LFRS) for multistory CLT structures. LFRS solutions such as steel frames, concrete cores, or...
This is a bibliography of the work of T. L. Jackson, who conducted research at the North Willamette Research and Experiment Center. It is limited to those Extension publications and research reports that addressed the nutrient needs of fresh market and processed vegetables.
The Coordinated Eastern Arctic Experiment (CEAREX) was a multi-platform geophysical study covering the period from winter 1988 to spring 1989 in the vicinity of the Yermak Plateau and Fram Strait. The Oceanography ("0") Camp component of CEAREX was designed to study the physical oceanographic conditions from the deep Nansen Basin...
This thesis traces the relationship between the First World War, constructions of masculinity, and the life and poetry of T.S. Eliot. Central to this relationship is a study of homoeroticism, which the author characterizes as different from homosexuality but not exclusive of it, in late 19th and early 20th century...
Establishing true depths of recovered sediments is critical to determining sedimentation rates for high-resolution paleoclimatic
studies. We have corrected the composite depth scale, which accounts for the entire continuous sedimentary sequence, so that sediment
depths are consistent with logging depths, or "true" depths. We accomplished this by taking advantage of...
A combination of theoretical perspectives is used to create a rich description of student reasoning when facing a highly-geometric electricity and magnetism problem in an upper-division active-engagement physics classroom at Oregon State University. Geometric reasoning as students encounter problem situations ranging from familiar to novel is described using van Zee...
It is possible to purchase, for as little as $10,000, a cluster of computers with the capability to rival the supercomputers of only a few years ago. Now, users that have little to no experience developing distributed applications or managing a cluster are in a position to do so. To...
Preliminary temperature microstructure profiles resulting from the FRONTS experiment in January 1980 are presented. Also included are selected profiles of the kinetic energy dissipation rate estimated by the Batchelor scale technique.
This report is a preliminary presentation of temperature microstructure
data resulting from the Mixed Layer Experiment (MILE) at Ocean
Station P (55°N, 145°W) during August-September 1977. During the MILE
experiment, the Caldwell research group conducted 381 casts over a period
of 21 days from the R/V OCEANOGRAPHER, using a Microstructure...
Observations of vertical temperature microstructure at ocean station P during the mixed layer experiment (Mile) indicate that the shape of the high-frequency temperature gradient spectrum depends on the relative strengths of turbulence and stratification. For low Cox number ((dT/dz)²)/ (dT/dz)²• the linear range of the Batchelor spectrum is not well...
The Arctic Internal Wave Experiment (AIWEX) was designed to study the internal wave and microstructure fields in the Beaufort Sea in the early spring. A major goal of the experiment was to verify the hypothesis that the internal wave and microstructure fields beneath the ice are far less energetic than...
Our primary purpose in developing this instrument is to measure
vertical temperature fluctuations in the ocean to the smallest scales at
which they exist. This goal dictates the basic concept of the instrument,
as C. S. Cox saw in the 1960's. Vertical temperature changes are seen
as changes with time...
This paper presents a seismic sequence and structural analysis of a high-resolution three-dimensional seismic reflection survey that was acquired in June 2000 in preparation for Ocean Drilling Program (ODP) Leg 204. The seismic data were correlated with coring and logging results from nine sites drilled in 2002 during Leg 204....
Coring at ODP Sites 859, 860, and 861 near the Chile Triple Junction failed to recover anticipated gas hydrate that was inferred
to be present from two lines of geophysical evidence: pre-cruise observation of a weak to strong bottom simulating reflector (BSR)
marking the predicted base of the gas-hydrate stability...
To facilitate the selection of drill sites for Leg 138, a site survey
program was conducted on board the Scripps Institution of
Oceanography's research vessel Thomas Washington (Cruise Venture
1). During this cruise, which departed San Diego on 30 August 1989
and arrived in Manzanillo, Mexico, on 4 October 1989,...
The immune system has been identified as a very sensitive target for the toxic effects of 2,3,7,S-tetrachlorodibenzo-p-dioxin (TCDD). Exposure to TCDD has been shown to disrupt the generation of both cell-mediated and humoral T cell-dependent immunity in laboratory animals; however, the mechanism remains unknown. In this dissertation, the hypothesis is...
Ocean Drilling Program (ODP) Leg 138 was designed to study the late Neogene paleoceanography of the equatorial Pacific Ocean at time scales of thousands to millions of years. Crucial to this objective was the acquisition of continuous, high-resolution sedimentary records. It is well known that between successive advanced piston corer...
In vitro growth of twelve isolates of Tither spp., the true truffles, was quantified by an agar-melt procedure. All isolates grew
poorly on media commonly used for the culture of mycorrhizal fungi, but responded markedly to the addition of nitrate, as well as other
inorganic ions, to malt and potato-dextrose...
Full-depth velocity and density profiles taken along the 3000-m isobath characterize the semidiurnal
internal tide and bottom-intensified turbulence along the Hawaiian Ridge. Observations reveal baroclinic
energy fluxes of 21 ± 5 kW m⁻¹ radiating from French Frigate Shoals, 17 ± 2.5 kW m⁻¹ from Kauai
Channel west of Oahu, and...
The primary objective of Leg 138 was to provide detailed information about the ocean's response to global climate change
during the Neogene. Two north south transects were drilled (95° and 110°W) within the region of equatorial divergence driven
upwelling (and thus high accumulation rates and resolution) and spanning the major...
We carried out a detailed rock magnetic and paleomagnetic study of deep-sea sediments from selected intervals of Site 1233 in order to assess whether they contain reproducible evidence for submillennial-scale environmental, climatic, and geomagnetic field variability. Three 1.5-m sediment intervals from oxygen isotope Stages 1, 2, and 3 were sampled...
Ocean Drilling Program (ODP) Leg 202 has opened a new window
into understanding late Paleogene and Neogene global environmental
change by providing high-quality sediment sequences from a previously
unsampled region, the eastern South Pacific. Eleven sites (1232–
1242) that record variations on timescales ranging from decades to tens
of millions...
We present benthic isotope stratigraphies for Sites 1236, 1237, 1239, and 1241 that span the late Miocene–Pliocene time interval from 6 to 2.4 Ma. Orbitally tuned timescales were generated for Sites 1237 and 1241 by correlating the high-frequency variations in gamma ray attenuation density, percent sand of the carbonate fraction,...
Longitudinal patterns of fish and benthic invertebrate distribution and
habitat use were similar in Thomas Creek, Oregon but clarity of these patterns
differed. I studied fish and aquatic invertebrates simultaneously, at multiple
scales, and used multivariate statistical techniques to compare responses to the
same environmental conditions. Both types of organisms...
Hydrographic and velocity profiles were made through a small baroclinic cyclonic eddy during the Arctic Internal Wave Experiment in the Canada Basin in April 1985. The maximum measured azimuthal velocity was 0.38 m s⁻¹ at a depth of 115 m, with velocities decaying to near zero at 30 and 270...
Post World War II victory culture and its fallout-the consensus ideology-led to the creation of a middle class willing to conform to a prescribed set of ideals, safely removed from all danger, and enjoying the material benefits of a growing middle-class income bracket. Walt Disney and Hugh Hefner, two seemingly...
The Thomas Kay Woolen Mill operated between 1890 and 1962. The mill produced predominately woolen blankets and woolen fabrics for outerwear garments.

Given the growing human security implications resulting from the high rates of change in social-ecological systems, the general question motivating this research is: how can the traditional security establishment respond to rising non-traditional threats? This question comes from the ongoing debate of whether military resources should be used in some...
The photoelectron spectra of a series of ketone
compounds have been investigated in the gas phase. Core
ionization energies were measured to probe the effects of
molecular size and connectivity number on core ionization
energies.
It was found that core ionization energies roughly
decrease with increasing connectivity number as expected....
A high-resolution primitive equation model simulation is used to form an energy budget for the principal semidiurnal tide (M₂) over a region of the Hawaiian Ridge from Niihau to Maui. This region includes the Kaena Ridge, one of the three main internal tide generation sites along the Hawaiian Ridge and...
Although IL-4 is a well-characterized multi-functional cytokine, its role as a survival factor in T cells is not completely understood. In an attempt to uncover IL-4-mediated survival, we studied caspase activation in primary mouse T lymphocytes undergoing death by neglect, activation-induced or steroid-induced cell death. Here, we identify the executioner...
