The ethyl acetate extract of the culture filtrate of the marine Ascomycete,
Leptosphaeria oraemaris (Linder) yielded a novel metabolite
designated by the common name leptosphaerin. An x-ray crystallographic
structure analysis was disproved by the synthesis of 3-acetoxy-S-(1,2-dihydroxyethyl)-
3-pyrrolin-2-one 1, starting with N,N-dibenzylhydroxylamine
47 and D-mannitol 44. Oxidation of 47 followed...
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. This thesis...
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...
In the problem of testing the median using a random sample from a
certain distribution, and if no other parametric family is suggested,
the t-test is known to be the optimal procedure when this distribution
is normal. If the sample appears to be non-normal, one has the choice
either to...
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...
The purpose of this work is to develop a new model for LDD
n-MOSFET degradation in drain current under long-term AC use
conditions for lifetime projection which includes a self-limiting
effect in the hot-electron induced device degradation.
Experimental results on LDD n-channel MOSFETs shows that the
maximum drain current degradation...
The effects of manganese nutrition on growth, mineral composition,
carbohydrate and nitrogen metabolism, IAA oxidase and phenols
of 'Northwest' strawberry plants are reported. Growth and mineral
composition response were investigated in sand culture and Hoagland's
solution 2 modified to contain 0.0, 0.5, 2.5, 12.5, 25.0, 62.5 and
125.0 ppm substrate...
The Transboundary Freshwater Dispute Database (TFDD) is a multifaceted global database that began in 1996 and includes a collection of international freshwater treaties, a database of water conflict-cooperation events, and a spatial database. Delineations of transboundary international river basin boundaries are the focus of the spatial database of which population,...
This paper focuses on Satan as a sympathetic figure in Paradise Lost, and it argues that readers' sympathy for Satan drives them to pursue God's grace in order to avoid falling into the same fate as Satan. It uses Reader Response theory to show how readers connect with Satan, and...
The electric motor has for an number of
years occupied an important position in the operation
of wood-working machinery, of moderate capacity, for
example the planing mills, sash and door factories
and many of the other similar wood working shops.

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...
