Eight foodborne pathogenic and spoilage Gram-positive bacteria were
evaluated for their spontaneous resistance frequencies to the peptide
antimicrobial nisin. In brain heart infusion (BHI) medium, nisin resistance
frequencies were in the range of l06 to l08 when exposed to nisin at
concentrations 2 to 4 times the minimal inhibitory concentrations....
Calanoid copepod diet was investigated in Oregon coastal waters to determine
the trophic significance of phagotrophic protists as copepod prey within an ecosystem
where the microplankton biomass is typically dominated by large diatoms. Prior to and
during the 1991 upwelling season, clearance rates on phytoplankton and phagotrophic
ciliates were measured...
In 1982 a protohistoric archaeological site along the Applegate River in southwest Oregon was excavated by Oregon State University Department of Anthropology. Three housepits and a possible menstrual but were uncovered with lithic, faunal, and archaeobotanical elements recovered from house floors and hearths. Seven botanical taxa were represented by carbonized...
This thesis examines how two grass seed industries
respond to changes in the production environment. Two sets
of factors are necessary to understand what adjustments
would be made. First, it is necessary to know the nature of
the markets and whether market power is being exerted.
Second we need to...
