In 1968 the Oregon Fish Commission (now Oregon Department of Fish and Wildlife) initiated P.L. 88-309 funded studies to develop techniques to spawn and rear several species of bay clams. After our successful spawning and rearing studies, we planted the laboratory-produced juvenile clams on various tideflats of several estuaries to...
The ability of Streptococcus diacetilactis to inhibit a variety of
food-borne pathogens and spoilage organisms in milk and broth cultures
was demonstrated. Test organisms inhibited included Pseudomonas
and Alcaligenes species, Eschericia coli, Salmonella, Staphylococcus
aureus, Clostridium perfringens and Vibrio parahaemolyticus.
In general, approximately 99.0% and 99.9% inhibition was
observed in...
A Bayesian approach to the analysis of a two-phase linear
regression model is given. It is assumed that the regression model is
continuous at the change point. The likelihood function is expressed
in a form which explicitly contains the continuity restriction. The
natural conjugate prior distribution for the likelihood function...
The major thrust of this research was to design, test, and
perfect an accurate and effective assessment technique, which would
result in becoming an assessment model. For the purpose of developing
this assessment model, the employment need for full-time
instructors of occupational subjects in the community colleges within
the state...
Major and minor minerals have been separated from
three L-6 chondritic meteorites (Alfianello, Colby (Wisconsin),
and Leedey). Olivine, hypersthene, diopside, feldspar,
troilite, chromite, phosphate minerals, and metallic
minerals were analyzed for major, minor and trace elements
using instrumental neutron activation analysis and radiochemical
neutron activation analysis techniques. Concentrations
df the...
Bush snap beans (Phaseolus vulgaris L.) cvs 'G5O' (Gallatin
50) and 'OSU58' (Oregon 58) were used for anatomical and morphological
studies of their responses to three levels of temperature.
The plants were grown in a controlled chamber under a 16-hour
photoperiod at 60°/50°, 70°/60° and 80°/70°F (day/night temperature),
respectively.
The...
In 1967, Doi et al. proposed the hypothesis that 'yellows type
diseases' are caused by mycoplasma. Since then more than 60
yellows diseases have been associated with mycoplasma-like bodies
(MLB) (Maramorosch, 1973). The majority of these associations are
based upon electron microscopic observations of mycoplasma-like
bodies in situ. However, little...
