The isolation, comparison, and attenuation of several viruses infecting Oregon salmonids

Creator:: McMichael, John Seiple
Abstract:: The Oregon strain of the agent of infectious hematopoietic necrosis (IHN) was isolated from fingerling sockeye salmon (Oncorhynchus nerka) by J. L. Fryer in 1958. Before the study reported herein no other virus had been recovered from any fish population in Oregon. Therefore, in July, 1971 a survey was initiated...

Long-term Fire Effects on Plant Succession and Exotic Weeds in Protected Area Sagebrush Steppe, John Day Fossil Beds National Monument, Oregon

Creator:: Reed-Dustin, Claire Marie
Abstract:: The historical function of fire in sagebrush steppe has been altered by 19th century overgrazing, active fire suppression, annual grass invasion and encroachment of woody species. The significance of fire to these systems is known, but research on long-term fire effects are limited. The Sheep Rock management unit of the...

Geographic variation in distribution and cover of principle native and non-native plant species along gradients of topography, climate, and disturbance in protected-area sagebrush steppe communities of the Columbia Plateau

Creator:: Esposito, Daniel M.
Abstract:: The sagebrush steppe ecosystem of the Columbia Plateau has become degraded by a long history of alternative land use and associated perturbations. Protection of remnant stands of intact sagebrush steppe currently relies upon their preservation within the nation's network of parks and protected-areas. The John Day Fossil Beds National Monument,...

Adaptation of molecular filtration for recovery of fish viruses from water

Creator:: Watanabe, Robin Aiko
Abstract:: The effectiveness of tangential flow filtration (TFF) for recovery of infectious hematopoietic necrosis virus (IHNV) and infectious pancreatic necrosis virus (IPNV) from large volumes of water was evaluated. In laboratory studies, virus recovery from IHNV-seeded water following concentration by TFF was approximately 13%. However, addition of 0.1 and 1% FBS...

Development of novel oral enteric-coated aquaculture vibrio vaccines

Creator:: Wong, George Kaon
Abstract:: An oral Vibrio vaccine for salmonids was developed. The vaccine was produced by spray coating lyophilized formalin-killed whole cells of Vibrio anguillarum (VA LS 1- 74) onto non-pareil sugar beads. Then methacrylic acrylic acid copolymer (Eudragit L-30D) was applied as an enteric protective coating. Using x-ray radiographic techniques, it was...

Introducing the Concept of Foundational Attributes and Project Metabolism to Assess Construction Project Similarity

Creator:: Zhang, Fan
Abstract:: A construction project is considered to be unique due to the process of delivering a customer-designed product, diverse stakeholders involved, the unique location and timeframe of construction, and specific social, economic, and environmental constraints attached to it. The uniqueness of construction projects brought great challenges to the construction industry professionals...

Strain differentiation and detection of infectious hematopoietic necrosis virus

Creator:: LaPatra, Scott Edward
Abstract:: The virulence of selected isolants of infectious hematopoietic necrosis virus (IHNV) were differentiated and correlated with electrophoretic mobilities of virion structural proteins by sodium dodecylsulfate polyacrylamide gel electrophoresis. A type 1 electropherotype of IHNV was more virulent for kokanee salmon (Oncorhynchus nerka) and a type 2 strain more virulent for...

Risk and Reward Perception and Risk-Taking: Applicability, Relationship, and Implication in Construction Safety

Creator:: Azeez, Mohammed N.
Abstract:: While safety improvements have been made in the construction industry, construction still experiences one of the highest numbers of fatalities annually compared to other industries in the United States with over 970 fatalities in 2016 alone. This number of fatalities drives researchers and safety managers to improve safety measures and...

Restructuring of land and community in the remote rural west : the case of Wallowa County, Oregon

Creator:: Abrams, Jesse
Abstract:: Since at least the 1970s, rural areas in the western United States, as elsewhere across the country and world, have been subject to social, economic, and political forces that have resulted in novel demographic and land tenure trends when compared to previous decades. Collectively, these processes of restructuring have created...

An examination of strategic challenges and opportunities in the wood-based building product industry

Creator:: Tokarczyk, John A.
Abstract:: The wood-based building products industry has experienced significant turbulence over the past several decades as a function of multiple forces including among others globalization, product and process innovation, and shifting customer and consumer interest and demands. Collectively, these changes have challenged the historical tenets which have defined industry strategy and...
