An emmission sampling system was developed to measure pollutants
emitted from a mobile agricultural incinerator developed at
Oregon State University. The system was designed to collect a particulate
sample on an 8" x 10" fiber glass filter and collect a gaseous
sample in a plastic bag. Pollutants measured were particulates...
Pediococcus cerevisiae, Lactobacillus casei, Lactobacillus plantarum,
Leuconostoc mesenteroides, Lactococcus diacetylactis Bifidobacterium
bifidum, Leuconostoc oenos, and mixed cultures of Propionibacterium
shermanii and P. cerevisiae were used to ferment cucumber juice brine
(CJB) at 22-26°C for 1.5 months. Sugar utilization ranged from 14.6 to 86.1%.
pH of the fermented CJB ranged from...
Pectinmethylesterase (PME) activity in fresh cucumber
fruit was determined. The effects of several cationic
species, temperature, pH, and acetic acid on the activity
of cucumber PME was investigated. The efficacy of
blanching, infiltration with CaCl₂ or acetic acid, and
fermentation with 0 and 40 mM CaCl₂ on inhibition of
cucumber...
In January-February 1971 five replicate 0.07 m² Van Veen grabs
were obtained from each of 12 stations in Arthur Harbor and nine Van
Veen grabs were obtained from two stations in nearby Bismark Strait.
The 69 grab samples yielded 78,395 individuals which were separated
into 282 taxa, including 108 species...
Beginning with the inception of American art history as a formal discipline in the 1940s, the dominant mode of interpreting nineteenth-century American landscape painting has been to view aspects of the landscape as symbols for grand cultural, religious, national, and moral narratives. While this method of interpretation highlights some key...
Pectic substances in the cell wall have long thought to
be responsible for the textural changes in fruit during
ripening and senescence. Compositional variation within
the pectic macromolecules could affect the external
characteristics of the fruit. Strawberries undergo adverse
quality changes such as softening and juice loss after
freezing and...
Dietary cyclopropenoid fatty acids (CPFA) have long
been known to cause pronounced physiological disorders in
both farm and laboratory animals. Past work has shown
CPFA to be a powerful promoter of carcinogenesis in trout,
rats and mice. Sterculic and malvalic acids (CPFA's) are
found in seed lipids of plants from...
