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...
The influence of irregular terrain on the evolution of the daytime
planetary boundary layer (PBL) and meso-β scale dry circulations is
studied using two three-dimensional hydrostatic σ-coordinate models
with different approaches for the PBL parameterizations; the 4-layer
model uses the mixed-layer (bulk-layer) approach, while the 7-layer
model adopts the eddy-diffusivity...
A pest management program for Tetranychus urticae Koch in Oregon
peppermint was developed based on studies of sampling, plant phenology,
population dynamics and damage thresholds.
A sample size of 45 leaves provided a confidence level of 90%
and a confidence interval of 50%. Estimation of the sample mean was
based...
Chalkbrood is a mycosis of larvae of the alfalfa leafcutting bee,
Megachile rotundata (Fabricius). It is a serious threat to alfalfa seed
growers in western North America who use populations of this bee for
pollination. Basic studies were conducted to determine the etiology of
this disease and the course of...
Three commercial sausage starter cultures were grown in
an internal-pH-controlled medium (PHASE 4) and in a soluble
phosphate-buffered medium. The cultures were tested by
comparing viable counts before and after freezing at -40 C
or freeze-drying and subsequent storage for 3 months in the
frozen or dried state. Strains varied...
