Spectral analysis was used to investigate semidaily mean sea
levels and atmospheric pressures at San Francisco, California,
Coos Bay, Oregon, and Tofino, British Columbia, in the frequency
band 0 to 0.5 cpd. Cross spectral analysis of semidaily mean sea
levels and atmospheric pressures at the three stations show that the...
The texture of processed berry fruits changes both during processing
and subsequent storage. A study was made of these changes
in processed strawberries, raspberries, blackberries, and blue-
berries, spin-cooked and stored at 100°F. for 28 days in tin and
glass containers. Four samples, from each of the two replications of...
The purpose of the present study was to investigate the effect
of a number of physical and chemical attributes upon muskmelon
texture as described by sensory evaluation. Measurements of turgor
pressure, percent moisture, total sugars, alcohol-insoluble-solids,
three pectic fractions, total pectic materials, starch and cellulose
were performed on 50 melons....
An improved procedure for the preparation of β-(3-cyclohexenyl) propionic acid from 4-vinylcyclohexene was developed. The
Friedel-Crafts cyclization of β-(3-(3-cyclohexenyl) propionyl chloride
with aluminum chloride was shown to give one bicyclic chlorine
containing ketone in 41% yield. This ketone was identified by a combination of spectral and chemical methods as a...
It is generally recognized that biochemical information is of
great importance to microbial taxonomy. This is particularly true
in the case of catabolic behavior of microorganisms in utilizing
glucose and allied compounds. Once the pathways operating in a
species are identified, and the relative participation of these pathways
is determined,...
Examination of a proposed reaction scheme to prepare bicyclo-(2.2.0)hexan-1-ol produced the first known condensation of an
enamine with its carbonyl precursor. Hydrolysis of the resulting
dienamine gave an unusual conjugated cyclobutenone in which the
double bond is exocyclic. Characterization and reactions of the
cyclobutenone were successfully carried out.
