This report describes the isolation of a new virus from adult
chum salmon (Oncorhynchus keta) returning to the Tokushibetsu Hatchery,
Hokkaido, Japan. The agent was isolated in the CHSE-214 cell line
derived from chinook salmon (Oncorhynchus tshawytscha). The virus
replicated in selected fish cell lines incubated between 10 and 20°C...
Chum salmon (Oncorhynchus keta) were artificially
infected with erythrocytic necrosis virus (ENV) to study
the physiological and hematolgical consequences of ENV-infection.
Infected and control fish were held in
pathogen-free seawater and sampled weekly for five weeks.
Physiological tests included plasma cortisol, glucose,
protein, and osmolality, blood lactic acid, and liver...
Nine isolates of bacteria recovered from fish dying at
marine facilities were collected from different geographic areas.
The strains included: an isolate from chinook salmon (Oncorhynchus
tshawytscha) reared in net pens in New Zealand, an isolate
from chum salmon (Oncorhynchus keta) held at a laboratory in
Oregon, USA., and seven...
A hierarchical series of studies, based mainly on molecular data, was conducted to elucidate the life history of the Douglas-fir Swiss needle cast pathogen Phaeocryptopus gaeumannii at macro- and micro-evolutionary scales. This information was then utilized to design and evaluate molecular diagnostic tools for use in studies on the epidemiology...
Juvenile English sole (Parophrys vetulus) were
collected in Yaquina Bay, Oregon from January, 1986 to
March, 1987. Recruitment of young-of-the-year sole
occurred from January to June, 1986 and again from
December, 1986 to February, 1987. Emigration from Yaquina
Bay started in September, 1986, but a small portion of the
English...
The hypotheses to be tested in this investigation are: 1) there is a threshold level of liver lipid and glycogen content above which the health condition of hatchery-reared fish is impaired, 2) fatty and high glycogen livers impair liver function and structure, and 3) fatty and high glycogen livers increase...
Traditional interpretations of James Joyce's Dubliners have often focused on the pervasive "paralysis" of the city, covered in the stories' range of "childhood, adolescence, maturity, and public life." However, these approaches have limited their focus on the women in the stories, often spotlighting the male characters--and the author--through a Freudian...
In his works, A Portrait of the Artist as a Young Man (1916) and Ulysses
(1922), James Joyce demonstrates what he perceives to be the paralyzing effects of
those institutionalized religions that sit at the center of cultures. Drawing on Michel
Foucault's analysis of institutional dressage as well as his...
Neutralizing monoclonal antibodies were developed against strains of infectious hematopoietic necrosis virus (IHNV) from steelhead trout Salmo gairdneri in the Deschutes River of Oregon, chinook salmon Oncorhynchus tshawytscha in the Sacramento River of California, and rainbow trout Salmo gairdneri reared in the Hagerman Valley of Idaho, USA. These antibodies were...
William James came of age at a time of great social and intellectual change in the United States. During this period, new professional identities proliferated, and a new culture of professionalization developed with important ramifications for conceptions of individual and social identity. Professionalization was also closely related to key intellectual...
The data is a JSON format file containing the position, velocity, and fish identifier data for 300 golden shiners in a shallow (depth of 4.5 to 5 cm) rectangular water tank (2.1 by 1.2 meters). There are 5000 individual frames (samples of position and velocity) corresponding to video taken at...
Basidiospores of Rhizopogon viriicolor Smith and R. colossus
Smith were inoculated onto container-grown Douglas-fir (Pseudotsuga
menziesii (Mirb.) Franco) seedlings and grown under two levels of
soluble fertilizer and one level of slow-release fertilizer. Both
fungi formed abundant (54%) ectomycorrhizae under the soluble
fertilizer regimes. Slow-release fertilizer greatly reduced percent
ectomycorrhizae...
This thesis discusses the African American authors Richard Wright and James Baldwin, and their views regarding how literature should be written. These views are examined as laid out in a selection of each author‟s essays, as well as through an analysis of the characters Bigger Thomas and Rufus Scott in...
The defining feature of our planet are the oceans, which make up 70% of the Earth’s surface. The importance of the ocean cannot be understated: 50% of oxygen originates from phytoplankton; heat is absorbed and redistributed by ocean currents; and hundreds of millions of people rely on the ocean for...
Senecio jacobaea (tansy ragwort) is a poisonous plant responsible
for livestock deaths in the Pacific Northwest. Horses and cattle are
susceptible, while sheep are resistant to the toxic action of the
pyrrolizidine alkaloids which the plant contains. Hepatic enzymes
are responsible for the biotransformation of pyrrolizidine alkaloids
into tissue damaging...
This is a set of documents and letters compromising a proposal by James McCauley to bring lobsters to the West Coast. The proposal involved the University of Rhode Island, the OSU Sea Grant Marine Advisory Program, Oregon State University, and the Oregon Fish Commission. The letters are to several people,...
The purpose of this thesis is to argue that LeBron James’ expressions of activism are, in many ways, perceived as insincere, hypocritical or disingenuous to his followers on the social media platform Twitter. Using the theoretical framework of Affect Theory and Plutchik’s wheel of emotions, a close reading was conducted...
This thesis examines depictions of medievalism in three central texts: Sir Walter Scott's Ivanhoe, Mark Twain's A Connecticut Yankee in King Arthur's Court, and George R.R. Martin's A Game of Thrones. Each of these texts provides an entry point for exploring the ways in which English and American writers have...
I experimentally test the hypothesis that the potential for selfing
increases with plant size in Mertensia ciliata (Boraginaceae), a self-compatible,
profusely-flowering perennial. This follows from the
premises that 1) pollen dispersal by pollinators between flowers is
limited, and 2) individual pollinators, in this study bumblebees, will
visit more flowers per...
Research on the population genetics of microbial organisms requires the use of specialized analyses designed for clonal organisms to avoid violating the assumptions of traditional population genetic models. The tools necessary for performing these analyses existed as a set of unrelated software with non-overlapping capabilities and did not cover all...
