An investigation was conducted in 1980 and 1981 on the larval
parasitoid complex of the orange tortrix, Argyrotaenia citrana
(Fern.), a major contaminant in cane fruits (Rubus spp.) in the
Pacific Northwest. A total of 13 parasitoid species were reared from
1,350 larvae predominantly collected from red raspberries in western...
Laser Scanning represents a new opportunity in forestry to effect meaningful change in the methods used for collection and analysis of inventory data. With the ability to collect spatial information in 360 degrees, while fluidly tracking the sensor and building the final point cloud, large tracks of terrestrial LiDAR based...
In this paper I discuss an ethnographic research project on identity embodiment among transgender and gender nonconforming punks in the Pacific Northwest region of the U.S., with focus on the relationship between transgender/gender nonconforming identity and affiliation to DIY punk communities. Trans punks create a unique, hybridized subculture-based identity embodiment...
Coreplication experiments have revealed that replication of
turnip yellow mosaic virus (TYMV) RNA in turnip protoplasts is cis-preferential.
Genomes encoding mutant p141 or p66, proteins
essential for virus replication, were inefficiently rescued by a
helper genome. One model for the cis-preferential replication of
TYMV is that p66 and p141 form...
The history of a software project plays a vital role in the software development process. Version control systems enable users of a software repository to look at the evolution of the source code, and see the changes that led to newer versions. Currently, version control systems provide commands that can...
Modern engineered systems are increasingly integrated into society, decentralized, and interconnected. However, scale and complexity create unique challenges in system design, such as emergent behavior and unintended consequences. This work investigates the structural characteristics of robustness in complex engineered systems by identifying patterns of under-recognized vulnerabilities at various levels of...
CIGS and CdTe based commercial thin-film solar cells (TFSCs) require an absorber thickness greater than 2 µm and 4 µm, respectively, to adequately absorb the solar spectrum. To efficiently extract photoexcited electrons, these TFSCs require relatively defect-free absorbers with high-minority carrier mobility (> 100 cm2V−1s−1) and long lifetime (> 10...
This prioritization is designed to provide strategic focus for tidal wetland conservation and a restoration actions undertaken in partnership with willing landowners. The study highlights locations in the Siuslaw River estuary where tidal wetland restoration or conservation action may offer the biggest ecological "bang for the buck" - this is,...
Time-dependent electronic transport is increasingly important to the state-of-the-art device design and fabrication. The development of nanoscale sensing, the harnessing and control of structural fluctuations, and the advancement of next-generation materials all require a treatment of quantum dynamics beyond the level of traditional methods and a more nuanced approach to...
Deforestation and loss of soil fertility are two forms of environmental degradation with global importance. Theories of environmental degradation commonly cited in public and academic discourse have historically emphasized the role of human populations and national economic development as being the primary drivers of environmental damage. This thesis utilizes quantitative...
