Long term albacore (Thunnus alalunga) spatio-temporal association with environmental variability in the Northeastern Pacific

Creator:: Phillips, A. Jason
Abstract:: This study investigated long-term (1961-2008) changes in albacore (Thunnus alalunga) abundance and distribution in relation to local environmental and large-scale climate indices in the Northeastern Pacific using time series and spatial analyses. Prior to the time series analysis, a wavelet analysis was conducted to examine nonrandom patterns of cyclical variability...

New insights on an old topic : understanding the effects of forest harvest on trout in the context of climate

Creator:: Penaluna, Brooke E.
Abstract:: Studies of the effects of forest harvest on streams and fish have a long history in the Pacific Northwest. Results of this work have prompted development of new forest harvest practices that are more protective of these resources, but the effectiveness of these new practices has not been fully evaluated....

Evaluating the Ecological Trade-Offs of Riparian Thinning for Stream Ecosystems in Second-Growth Redwood Forests of Northern California

Creator:: Roon, David A.
Abstract:: Riparian forests provide a myriad of ecosystem functions for adjacent streams and rivers, and due to these linkages, changes in riparian forest conditions can have direct implications for stream ecosystems. Resource managers in the coast redwood forests (Sequoia sempervirens) of northern California (USA) are actively thinning second-growth stands to accelerate...

Headwater Dynamics: Quantifying Spatial Differences in Flow Permanence and Network Connectivity across Diverse Landscapes

Creator:: Pate, Adam A.
Abstract:: Forested headwater streams are critical for the supply of water, sediment, nutrients, and organic matter to downstream water bodies. Nearly half of all headwater streams display temporary flow regimes (i.e., non-perennial), but with climate change they may become more common. Thus, it will be increasingly imperative to adequately represent non-perennial...

Chromium Phillips Catalyst on Tin Oxide Substrate: Deposition and Characterization

Creator:: Chen, Di
Abstract:: In order to synthesize polyethylene by the microreactor with a catalyst, this thesis prepares the chemical coating layers for the reactor channel. There are two layers in the channel: the Phillips catalysts and an antimony-doped tin oxide layer on glass substrate. The Phillips catalyst help to synthesize polyethylene in the...

Internal curing of high-performance concrete for bridge decks

Creator:: Deboodt, Tyler
Abstract:: High performance concrete (HPC) provides a long lasting, durable concrete that is typically used in bridge decks due to its low permeability, high abrasion resistance, freeze-thaw resistance and strength. However, this type of concrete is highly susceptible to the deleterious effects of both autogenous and drying shrinkage. Both types of...

Vegetation and Small Mammal Responses to Western Juniper (Juniperus occidentalis) Control in Eastern Oregon

Creator:: Morozumi, Corinne N.
Abstract:: Shrub-steppe ecosystems of western North America provide habitat for many wildlife species, are important components of public and private rangelands, and offer recreational opportunities for millions of people. They are some of the most vulnerable ecosystems in the United States and have been altered by human activities such as livestock...

Improving the Performance of High Early Strength Concrete by Controlling Self-Desiccation and Mitigating Shrinkage

Creator:: Wilson, Cameron A.
Abstract:: High early strength (HES) concrete is becoming increasingly used to repair damaged concrete pavement sections. The use of HES concrete enables the repaired pavement to be opened to traffic within hours of placing the concrete. A common approach used for the rapid repair of concrete pavement consists of closing a...

Tracking Competitive Season Training Load via TRIMP in a Collegiate Distance Runner : A Case Study

Creator:: Anderson, Morgan Jane
Abstract:: Objectively quantifying workload is challenging due to a variety of factors. One way to measure workload is by training impulse (TRIMP). TRIMP uses time in physiologically significant heart rate zones to quantify a workload for a given bout of physical activity. Tracking average workload over time can then be used...

A Comprehensive Mechanistic Study on Using Fine Lightweight Aggregate to Mitigate Alkali-silica Reaction

Creator:: Li, Chang
Abstract:: Previous research has shown that using fine lightweight aggregate (FLWA) can be a promising strategy to mitigate alkali-silica reaction (ASR) in mortar and concrete. While several possible theories were proposed by researchers, discrepancies in testing methods, materials, and supporting evidence still exist. Therefore, this study was initiated. There are two...
