The Mount St. Helens eruption of May 18, 1980, offered an
excellent setting for evaluating early response of ecosystems to
disturbance. Prior to the eruption, the area was densely forested
with fir, hemlock, and Douglas-fir, and various understory species.
During the course of the eruption, hillslopes within a 180 degree...
The purpose of this phenomenological study was to discover the experiences nurse educators (NEs) have had with oppression and to uncover how their experiences may have impacted their teaching. This study was significant as nurse retention is negatively affected by oppressed group behaviors (Duchscher & Myrick, 2008; Tinsley & France,...
Mixtures of 1,4-dioxane (1,4-D) and chlorinated aliphatic hydrocarbons (CAHs) are common and hazardous groundwater contaminants that can be challenging to address with traditional remediation strategies. Bioremediation through aerobic cometabolism has the potential to be an effective in-situ treatment strategy for these contaminants. Rhodococcus rhodochrous strain ATCC 21198 is capable of...
The global mid-ocean ridge system is the largest magmatic system encompassing over 75% of the Earth’s total volcanism. As magmas ascend through the vertically variable oceanic crust, melts begin to crystallize and diversify and subsequently erupt at the surface. The interpretation of these erupted products observed on the seafloor requires...
Butane-grown Pseudomonas butanovora oxidized butane by a soluble butane monooxygenase through the terminal pathway yielding 1 -butanol as the predominant product. Alcohol dehydrogenases (ADHs) involved in butane oxidation in P. butanovora were purified and characterized at the biochemical, genetic and physiological levels. Butane-grown P. butanovora expressed a type I soluble...
The Mw7.5 Palu-Donggala earthquake occurred on 28 September 2018 at 6:02 PM local time, and was caused by strike-slip faulting along the north-south trending Palu-Koro fault that extends through Palu City and the Central Sulawesi region of Indonesia. The United States Geological Survey (USGS) reports the epicenter was approximately 72...
Auxin and ethylene regulate many important aspects of plant growth and development and are
essential to the plants survival. They help regulate such diverse processes as cell elongation,
growth of adventitious roots, fruit growth, germination, and a variety of other processes. Few
studies have examined how the hormones auxin and...
This project explored one set of tools and procedures that
appeared to have the potential to make the handling of the spatial
data necessary for resource management more efficient and
effective. This project used data from the Nature Conservancy's
Lawrence Memorial Grassland Preserve and was designed to explore
a low...
The West Eugene Wetlands, Eugene, Oregon, which provide habitat for number of endemic and endangered plant species, are currently threatened by a Reed canarygrass (Phalaris arundinacea L.) invasion. This study addresses the hypothesis that Phalaris spread can be explained in part by using watershed-scale landuse patterns as surrogates of the...
Proteinase P-II purified from parasitized Pacific whiting muscle was previously
identified to be one form of cathepsin L. It appeared to be present in three isozymatic
forms on non-denaturing PAGE gel stained for activity. Its autolytic degradation was
observed on SDS-PAGE gel under its optimum condition, 55°C and pH 5.5,...
