Microwave methods of measuring resistivity of gallium arsenide

Creator:: Quinn, Alexander C.
Abstract:: This paper is concerned with the determination of gallium arsenide resistivity by measurement of attenuation of microwave energy at 7500 megacycles transmitted through a slice. The first section of this paper describes gallium arsenide properties as compared to silicon, germanium, silicon carbide, and diamond. A description is then given of...

Gamma irradiation inactivation kinetics of medically important bacteria contaminating seafoods

Creator:: Quinn, Dorothy Jean
Abstract:: Gamma irradiation inactivation kinetics were studied using fifteen organisms naturally contaminating seafoods. Survival curves for seven Salmonella, three Shigella, two Streptococcus species and a Staphylococcus, Escherichia and Proteus species were determined using Hartsell's broth and fresh oysters. Also, the Shigella species and one species of Streptococcus, Escherichia and Proteus were...

Otolith Morphometrics as a Tool for Conservation and Management of Chinook Salmon (Oncorhynchus tshawytscha)

Creator:: Koeberle, Alexander L.
Abstract:: Chinook salmon are widely distributed across the globe with native stocks in the North Pacific Ocean and self-sustained populations introduced to regions in the Northern and Southern Hemispheres. Pacific salmon are economically and ecologically important to the Pacific Northwest, USA, yet several wild populations are federally listed as endangered or...

Intestinal Lesions and Parasites Associated with Senescence and Prespawn Mortality in Chinook Salmon (Oncorhynchus tshawytscha)

Creator:: Nervino, Stephanie A.
Abstract:: Pre-spawning mortality (PSM) presents a major problem for population recovery of spring Chinook salmon (Oncorhynchus tshawytscha) in the Willamette River basin. In certain reaches and years, PSM has exceeded 90%. Histology has been used as the primary diagnostic method to investigate PSM in the Chinook Salmon, and a collection of...

Assessing disease impacts of hatcheries on downstream salmonids in the Willamette River Basin, Oregon

Creator:: Jakaitis, Michelle
Abstract:: Hatcheries are often perceived as a source of pathogen amplification, potentially increasing disease risk to free-ranging populations; at the same time, free-ranging fishes may introduce pathogens into hatcheries through untreated water sources. Many pathogens exist naturally within the environment (with the exception of introduced pathogens) and the presence of a...

Reconnecting aquatic habitats : validating historical habitat use by anadromous fishes using telemetry and stable isotope analysis above barriers

Creator:: Lewis, Sierra Koch
Abstract:: I conducted a study to identify potential spawning habitat for anadromous salmonids above a 60-year-old hydropower dam in the headwaters of the North Umpqua River in Oregon. Like many other historical salmonid-bearing rivers, little documentation exists for anadromous fish presence above potential natural obstacles upstream of Soda Springs Dam. My...

Survival curves of bacteria with public health significance irradiated in crabmeat and in Hartsell's broth

Creator:: Nazeeri, Patsy Lundsteen
Abstract:: Gamma irradiation survival curves of Salmonella enteriditis, Salmonella paratyphi A, Salmonella cholerasuis, Salmonella pullorum and Streptococcus pyogenes were determined in crabmeat and in Hartsell's broth. The survival pattern of Staphylococcus aureus in crabmeat was also determined. A "tailing off" was found in the survival patterns of Salmonella paratyphi A, Salmonella...

Soil Development and Organic Carbon Stocks Across a Lithosequence in the Perhumid Coastal Temperate Rainforests of Southeast Alaska

Creator:: Fedenko, Jennifer M.
Abstract:: The perhumid coastal temperate rainforests of southeast Alaska contain an abundance of soil organic carbon (SOC) that has accumulated in a wet, cool climate where forest fire disturbance is minimal and organic matter decomposition rates are low. Coastal temperate rainforests are supported by carbon-rich soils that provide ecosystem services including...

Temporal Variation in the Prey Resource Portfolio of Juvenile Salmonids During Freshwater Rearing

Creator:: Brady, Megan E.
Abstract:: Freshwater rearing is a critical period in the life cycle of anadromous salmonids, known to produce carry-over effects mediating long-term growth and survival. Freshwater growth is primarily determined by food availability and temperature. While many species of salmon rear in freshwater for a full year or longer, most trophic ecology...
