The purpose of this study was to identify learning activities that
were both Future Homemakers of America/Home Economics Related
Occupations goal-related and realistic for use in the home economics
classroom. The hypothesis tested was: there is no significant difference
between mean scores of individual learning activities related
to FHA/HERO goals...
Growth and enterotoxin production of Staphylococcus aureus in papain-treated beef and ham were studied. In addition to an untreated control, four treatments were used in the beef experiment including two levels of papain, a commercial tenderizer preparation, and commercially tenderized beef. Two levels of papain treatment and an untreated control...
Symbiotic associations are established between non-leguminous
(actinorrhizal) nitrogen-fixing flowering plants and two categories
of microorganisms: mycorrhizal fungi and a filamentous actinomycete.
The actinomydete induces nodule formation and produces nitrogenase,
the enzyme responsible for the reduction of atmospheric nitrogen to
a form available to higher plants. The mycorrhizal fungus is found...
A major problem of this study was to assess a model for predicting attitudes and behavior of vocational teacher trainees toward handicapped learners. A second problem was to determine whether or not both attitudes and behavior of vocational teacher trainees toward handicapped learners could be changed. The sample for this...
The arthropod community in a Douglas-fir forest near Blue River, Lane County, Oregon was investigated from March through August 1973. Five stands of Douglas-fir were sampled: two clearcuttings, a young-growth
(20 years old), a midgrowth (125 years old), and an old-growth (450 years old) plot. A pole pruner was used...
In 1960 a program of monitoring the zooplankton populations of Yaquina Bay, Oregon, was begun. The frequency of sampling was maintained at close to weekly intervals after 1 January 1963, usually at five stations. Abundances of all the species found in the bay of both meroplankton and holoplankton have been...
Insects represent the most diverse and abundant group of consumers
know. The overall objective of this study was to obtain relative density
estimates of the dominant taxa and identify their primary functions in
order to assist consumer modelling efforts.
