The Federal Water Pollution Control Act Amendments of 1972
prohibits the discharge of seafood processing solid wastes into
navigable waters after July 1, 1977. Oregon shrimp and crab processors
must use other methods of disposal for the 15 to 30 million
pounds of solid waste generated annually. The application of...

A THESIS

A survey of the methods of purification of KC1, for use in
preparing single crystals by growth from the melt, was made. Two
methods, fractional recrystallization and ion exchange, were used.
The purity of the salt and crystals grown from the same salt were
compared with the findings of other...
This report presents a characterization of the quantum mechanical
analog of the Gibbs canonical density. The approach is
based on a method developed by D.S. Carter for the case of classical
statistical mechanics, which considers composite mechanical systems
composed of mechanically and statistically independent components.
After a brief introductory chapter,...
The present study is an attempt to investigate some of the relationships
between certain personality characteristics and expressed
preferences for various communication structures; it is also an
examination of the relative efficiency of the networks used.
Subjects drawn from the university population participated in
experimentally formed five-person groups. These groups...
The three-phase squirrel-cage induction motor is rugged, compact,
inexpensive, can be totally enclosed and requires little maintenance.
Its use as a variable speed drive has been limited, however, by the
state-of-the art of control components.
The advent and continuing development of the silicon controlled
rectifier and associated solid-state components has...
When the dc conductivities of various pure KC1 crystals were
compared it was found that crystals grown under an HC1 atmosphere,
from salt purified by ion exchange, exhibited lower knee temperatures
than any of the crystals studied. These knee temperatures
were found to be approximately 350°C. From this the total...
Purebred Yorkshire gilts from a confinement managed herd were reared to test weights away from the sow and boar herd. Thirty-eight gilts weighing between 73 and 80 kilograms constituted group A gilts; 38 gilts weighing between 91 and 100 kilograms constituted group B gilts; and 47 gilts weighing 114 kilograms...
The Hemigrapsus oregonensis population at Coquille Point in
the Yaquina Bay Estuary on the Central Oregon Coast was studied
from April, 1972 through May, 1973. The population was found to be
vertically stratified from the 1 ft level to the 5 ft level. Population
densities were found to be most...
L1R, a myristylated late gene product of vaccinia virus, is essential for formation of infectious intracellular mature virions (IMV). In its absence, only viral particles arrested at an immature stage are detected and no infectious progeny virus are produced. Previous studies have shown that the L1R protein is exclusively associated...
Recreational angling pressure has recently increased in the neritic
reef areas off the central Oregon coast. This study describes
weight-length and age-length relationships as well as ages at sexual
maturity of the black, blue, canary, yelloweye, and yellowtail rockfish
(Sebastes melanops, S. mystinus, S. pinniger, S. ruberrimus, and
S. flavidus,...
Agriculture is now facing the ‘perfect storm’ of climate change, increasing costs of fertilizer and rising food demands from a larger and wealthier human population. These factors point to a global food deficit unless the efficiency and resilience of crop production is increased. The intensification of agriculture has focused on...
Pacific Northwest trawl fishermen spend an estimated $625,000 every year to replace corroded trawl cable. If the Pacific Northwest shrimp fleet is included, the yearly cost greatly exceeds one million dollars. Fishermen could save hundreds of thousands of dollars and increase the net return to the individual fisherman if they...
Practical hydrostatic ocean models are often restricted to statically stable configurations by the use of a convective adjustment. A common way to do this is to assign an infinite boat conductivity to the water at a given level if the water column should become statically unstable. This is implemented in...
The relationship between nitrogen (N) availability and the growth of macroalgae in a seasonal upwelling region (Yaquina Head, Oregon, USA) was investigated. Water column nutrient concentrations were relatively high and stable during the winter, decreased in early spring, and were highly variable in the summer and early fall. Periods of...
Nitric oxide (NO) is an essential agent of the innate immune system which exhibits multi-mechanistic antimicrobial activity. Previously, increased antimicrobial activity against E. coli with nitric oxide releasing nanoparticles (NO-np) was demonstrated when combined with glutathione, versus NO-np alone, due to formation of S-nitrosoglutathione (GSNO), a potent transnitrosylating agent. To...

The Global Earthquake Model (GEM) aims to develop uniform, openly available, standards, datasets and tools for worldwide seismic risk assessment through global collaboration, transparent communication and adapting state-of-the-art science. GEM Faulted Earth (GFE) is one of GEM’s global hazard module projects. This paper describes GFE’s development of a modern neotectonic...
The Northwest forest products industry has been under severe economic pressure for the past several years. Many Northwest forest products companies have gone out of business entirely and others have closed portions of their operations. This monograph describes how one company has instituted a productivity improvement program to reduce its...
Surface heat flux components are estimated at a midshelf site over the northern California shelf using moored measurements from the 1981-1982 Coastal Ocean Dynamics Experiment (CODE) and the 1988-1989 Shelf Mixed Layer Experiment (SMILE). Time series of estimated fluxes extend from early winter through summer upwelling conditions, allowing examination of...

Stressors associated with human activities interact in complex ways to affect marine ecosystems,
yet we lack spatially explicit assessments of cumulative impacts on ecologically and
economically key components such as marine predators. Here we develop a metric of
