Escape in Time: Phenology Mitigates Impacts of the Introduced Cinnabar Moth, Tyria jacobaeae, on Native Herb Senecio triangularis in Western Oregon

Creator:: Lunde, A. Katarina
Abstract:: Classic biological control can be a powerful option for those tasked with managing biological invasions; however, some biocontrol releases lead to non-target attack – feeding, damage or development on species other than the target species. The cinnabar moth, Tyria jacobaeae L. (Lepidoptera: Erebidae) was introduced to Western Oregon as a...

Experimental Investigation of the Effects of Embedded Rebar, Cracks, Chloride Ingress and Corrosion on Electrical Resistivity Measurements of Reinforced Concrete

Creator:: Morales, Monica
Abstract:: The effects of steel reinforcement, chloride-induced corrosion initiation, cracking and delamination on the electrical resistivity measurements using the Wenner probe technique were studied experimentally on custom-designed reinforced concrete slabs. Investigation parameters included (1) probe configurations with respect to rebar mesh, (2) rebar density, (3) epoxy coating on the rebar, (4)...

Treatment options for controlling Brachypodium sylvaticum and impacts on native vegetation

Creator:: Fjeran, Taylor K.
Abstract:: Invasive vegetation control studies traditionally aim to control existing populations as well as limit future spread of the species. However, little additional attention has been dedicated to aiding native communities to recover and reestablish. One prominent example of a studied invasive is Brachypodium sylvaticum (Huds.) P. Beauv. (false brome), a...

Engineering Services of Submerged Aquatic Vegetation (SAV): Investigation of the Land-Building and Energy-Attenuating Properties of SAV Habitats Across Spatial Scales

Creator:: Holzenthal, Elizabeth R.
Abstract:: 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,...

Assimilation of Multi-Sensor Data into Numerical Hydrodynamic Models of Inland Water Bodies

Creator:: Javaheri, Amir
Abstract:: Numerical models are effective tools for simulating complex physical processes such as hydrodynamic and water quality processes in aquatic systems. The accuracy of the model is dependent on multiple model parameters and variables that need to be calibrated and regularly updated to reproduce changing aquatic conditions accurately. Multi-sensor water temperature...

Active Learning and the ALEKS Placement Test in College Algebra : An Observational Study

Creator:: Dean, Raven
Abstract:: In 2012, a university in the north western United States began offering a redesigned college algebra class that had a greater emphasis on active learning. Specifically, two out of four class periods were completely devoted to students working together in small groups on carefully designed worksheets. Two years later, the...

Technology to promote concept-based, active learning and enable education research

Creator:: Brooks, Bill J.
Abstract:: This dissertation centers on development of two web-based, in class learning tools, the AIChE Concept Warehouse (CW) and the Web-based Interactive Science and Engineering Learning Tool (WISE), and describes the investigation of student learning through their use. The intent of these tools is to promote deeper conceptual understanding in students...

An experimental study of laminarization induced by acceleration and curvature

Creator:: Jackson, R. Brian
Abstract:: The Generation IV Very High Temperature Reactor (VHTR) design is being actively studied in various countries for application due to its inherent passive safe design, higher thermal efficiencies, and proposed capability of providing high temperature process heat. The pebble bed core is one of two core designs used in gas...

Cherry phytochemicals

Creator:: Chaovanalikit, Arusa, 1974-
Abstract:: The distribution of anthocyanin pigments and polyphenolics of sweet (Prunus avium) and sour cherries (Prunus cerasus) were determined by Ultraviolet- Visible (UV-Visible) spectrophotometry and High Performance Liquid Chromatography with photodiode array detector (HPLC-DAD). Their antioxidant properties were determined by Oxygen Radical Absorbance Capacity (ORAC) and Ferric Reducing Antioxidant Power (FRAP)....

Assessing the sustainability of management practices for planted forests across an environmental gradient in New Zealand

Creator:: Kiyvyra, Alicia L.
Abstract:: Sustainable management of planted forests requires maintenance of soil function to promote 1) root growth; 2) storage and cycling of water and nutrients; 3) optimal gas exchange; and 4) biological activity. Soil quality measurements can be used to monitor short- and long-term changes in these soil functions, allowing managers to...
