Model development via delay extraction for the time-domain simulation of lossy transmission lines.

Creator:: Blevins, Chris
Abstract:: This thesis presents two new approaches for the broadband, time-domain modeling of lossy transmission lines. Each approach is based on an alternative derivation of delay extraction in order to separate the line's linear phase from its attenuation and dispersion. Augmentation networks represent the derived attenuation networks as rational function approximations....

Use of Landscape Characteristics to Quantify Hybridization Risk Between Native and Introduced Salmonids

Creator:: Manning, Michael A.
Abstract:: The introduction of non-native species can negatively impact native species through reduced genetic fitness resulting from hybridization. The lack of spatiotemporal data of hybrids occurrences makes assessing hybridization risk difficult. Here, I developed a spatially-explicit GIS Hybridization Risk Model (HRM) between native ESA-listed Bull Trout and introduced Brook Trout by...

Long-term Impacts of Nitrogen Fertilizer, Tillage and Crop Residue on Soil and Plant Nutrients in Winter Wheat Cropping Systems Under Dryland Conditions

Creator:: Shiwakoti, Santosh
Abstract:: Agricultural practices influence the nutrient dynamics of soil and plants, which may take more than a decade to be expressed in the drylands. The nutrient supplying capacity of soil is a crucial component of sustainable agriculture, and hence, this study can play an important role in policy making for the...

Confessing Our Sims: The construction of gender and sexuality among women ages 18-22 on MySpace

Creator:: Papaleo, November R.
Abstract:: MySpace is a social network phenomenon with over 100 million profiles and a strong presence in over 24 countries. As digital media become more commonplace, social networks are becoming sites where women create and manage relationships and identities. This thesis is a study of how women ages 18-22 are constructing...

Deposition and characterization of transition metal oxides from aqueous solution

Creator:: Betterton, Sharon A.
Abstract:: The aqueous chemistries of two transition metal cations, Zr⁴⁺ and Nb⁵⁺, are examined and then used to develop inorganic precursor solutions. The oxides of these cations (ZrO₂ and Nb₂O₅) are deposited and characterized, and their morphological and optical properties discussed. Due to the obstacles created by niobium's aqueous chemistry, an...

Nitrogen dynamics across silvicultural canopy gaps in young forests of western Oregon

Creator:: Thiel, Aaron L.
Abstract:: Silvicultural canopy gaps are emerging as an alternative management tool to accelerate development of complex forest structure in young, even-aged forests of the Pacific Northwest. I investigated patterns of nitrogen (N) availability along transects through 0.1 and 0.4 ha silvicultural gaps in three 50-70 year old Douglas-fir forests of western...

Processing and functional diversity of plant microRNA

Creator:: Cuperus, Josh
Abstract:: RNA interference pathways can involve amplification of secondary siRNAs by RNA-dependent RNA polymerases. In plants, RDR6-dependent secondary siRNAs, including transacting siRNAs (tasiRNAs), arise from transcripts targeted by some microRNAs (miRNAs). In the case of TAS3 tasiRNA formation, ARGONAUTE7 (AGO7)-miR390 complexes interact with primary transcripts at two sites, resulting in recruitment...

Decomposition and nitrogen dynamics of red alder and Douglas-fir leaf litter in Oregon Coast Range riparian forests

Creator:: Matkins, Joselin
Abstract:: I examined factors regulating decomposition rates of red alder (Alnus rubra)) and Douglas-fir (Pseudotsuga menziesii) leaf litter in Coast Range riparian areas in western Oregon. Overall, this study was designed to examine the influence that leaf litter quality characteristics and decomposition site treatment have on decomposition rates, to provide a...

Temperature stress, gene expression, and innate immunity at the onset of cnidarian-dinoflagellate symbiosis

Creator:: Schnitzler, Christine E.
Abstract:: The intracellular mutualism between cnidarians and photosynthetic dinoflagellates (genus Symbiodinium) is responsible for the physical and trophic structure of diverse coral reef ecosystems. This relationship, based on nutrient exchange, allows for high productivity in tropical waters, which are generally nutrient-poor environments. Numerous environmental stressors currently threaten the health of corals,...

Role of IL-8 and TIMP-2 on term canine trophoblast migration, invasion, and proliferation

Creator:: Gullaba, Justine Marie
Abstract:: Placental pathologies are not uncommon in dogs. For example, in primiparous bitches, the reported incidence of subinvolution of placental sites is 21% - 100%. Despite years of research in multiple species, the mechanisms regulating late gestation trophoblast behavior in the dog remain unexamined. Therefore, the objective of this study was...
