The words we use to define our lives are often determined by the way we render any given moment. Every instance of writing is a moment of remembering, and a non-fiction essay gives the author free rein to unravel an instance, paint a portrait of what time has already come...
T cells are one of the key cells in the immune system. Although they are not the first line of defense against a pathogen, their functions can greatly enhance the phagocytosis and destruction of pathogens as well as the development of antibody responses. Furthermore, even when responding T cells have...
Maps from the report "Modeling sea level rise impacts to Oregon’s tidal wetlands : Maps and prioritization tools to help plan for habitat conservation into the future.”
Historical forest harvesting practices were reviewed in the original Alsea Watershed Study where they found increased energy
loading to the stream and produced higher stream temperatures. This was an important early research site that led to the
development of contemporary forest management practices to protect water quality and fish habitat...
Aerodynamic roughness heights of 1–3 cm were obtained from measured wind profiles collected among
fields of gravel-mantled megaripples in the high desert of the Puna region of northwestern Argentina.
Roughness height appears to be relatively insensitive to the angle at which the wind was incident upon
the bedforms throughout the...
Worldwide production of natural gas has surged in the last few decades leading to an economic windfall for many communities, but sometimes these new sources of natural gas are located in geographically isolated locations. These areas are so remote that it isn’t economically feasible to transport this stranded gas to...

Microtechnology was used to study the chemical reduction of dissolved carbon dioxide into useful products. A novel TiO₂ photocatalyst was used to activate the reaction under ultraviolet irradiation. CO₂ was dissolved in aqueous and 50% BMIM-BF₄ (ionic liquid) solutions. The introduction of an ionic liquid increased the solubility of CO₂...
It has long been recognized by the legal community that when an immigrant seeks relief from deportation proceedings through the United States’ immigration courts, the proceedings they undertake are best seen as a game of chance depending on the Immigration Judge who is randomly assigned to their case.

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...

Over the course of the last century, a successful history of fire suppression has contributed to unsuccessful present day control over wildfire. In the absence of fire and the janitorial and ecological services it provides, drier inland forests are shifting in species composition and exceeding densities that cannot survive and...
The study of the diversity of multivariate objects shares common characteristics across disciplines, including ecology and organizational management. Nevertheless, experts in these two disciplines have adopted somewhat separate diversity concepts and analysis techniques, limiting the ability of potentially sharing and cross comparing these concerns. Moreover, while complex diversity data may...
2,3,7,8-Tetrachlorodibenzo-p-dioxin (TCDD) and related compounds are well-recognized for their immunosuppressive activity, which is mediated through an intracellular receptor and transcription factor, aryl hydrocarbon receptor (AhR). Laboratory animals exposed to TCDD are less resistant to infection and have severely impaired humoral and cell-mediated immune responses. This dissertation addressed the hypothesis that...

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...

The inner bark of Douglas-fir was successively extracted with ethanol-water (4:1 v/v), benzene-ethanol (2:1, v./iv), water, and 0.5% aqueous ammonium oxalate solution. The residue was reacted with acidified sodium chlorite, a commonly used reagent to separate lignin from carbohydrates. In general the reaction dissolves the lignin and leaves the carbohydrates...
Submerged aquatic vegetation (SAV) species, such as seagrasses, are highly valued in estuaries because of the many economic, ecological, and cultural services that they provide, including shelter for fisheries, minimizing water turbidity, and improving am-bient water quality. SAV can also alter its physical environment by attenuating wave and current velocities,...
The spectrophotometric titration of the tyrosine residues,

The conventional view of equatorial dynamics requires that the zonal equatorial wind stress be balanced, in the mean, by the vertical integral of “large-scale” terms, such as the zonal pressure gradient, mesoscale eddy flux, and mean advection, over the upper few hundred meters.

Proper immune function is indispensable, as failure to mount an immune response against a pathogen can lead to serious complications or even death. T cells act by enhancing the activation of phagocytic cells as well as the activation of B cells. Their widespread influence on an immune response makes optimal...
The immune toxicity of 2,3,7,8-Tetrachlorodibenzo-p-dioxin (TCDD) has been studied for over 35 years, but only recently has the profound immune suppression associated with TCDD exposure been linked to induction of regulatory T cells (Tregs). The effects of TCDD are mediated through binding the aryl hydrocarbon receptor (AhR), a ligand-activated transcription...
This thesis traces the relationship between the First World War, constructions of masculinity, and the life and poetry of T.S. Eliot.
