In recent years the types of engineering data accumulated by many telemetry systems have become so diversified and complex, and
the environment in which these systems operate has become so restricting
that telemetry systems with increased capabilities and decreased
size are becoming a necessity. Advances in integrated circuitry
techniques satisfy...
During a study of the abnormal dienone-phenol rearrangement
discovered by Marvell and Geiszler, Imel (1960) found that 4-oxo-3,3-dimethyl-3,4-dihydrophenanthrene rearranged slowly to a phenol
which was tentatively identified as 3,4-dimethyl-l-phenanthrol;
further evidence to support this assignment was deemed essential.
The recent work by Mallory on the photochemical conversion of
stilbenes to...
This report measures the effects of logging on the production and yield of Coho salmon, coastal cutthroat, and steelhead trout in small coastal streams. It contains descriptions of the physical and biological environment before logging, and describes some immediate effects of logging, such as such as a decrease in dissolved...
Milk, preheated at 82°C for 30 minutes, was heated to 146°C
for four seconds (UHT-treated) and cooled to 5°C in a tubular heat
exchanger. Immediately after heat treatment, 20 gallons of heated
milk were vacuum distilled at 30°C in a semi-continuous, reduced
pressure glass apparatus. Twenty gallons of non-heated milk...
A study was conducted on German velvetgrass (Holcus mollis L.), a weedy, rhizomateous perennial grass introduced in the
United States in relatively recent years, The purpose of this study
was to learn more about its distribution, growth habits, and control
under conditions found in Western Oregon. German velvetgrass infestations of...
Iodoacetic acid and diphenylamine were used in this study to
elucidate the mechanisms of resistance of Micrococcus radiodurans
to radiation. This organism, a gram positive, non-spore forming,
salmon-pink, tetracoccus has a LD₅₀ of 213,000 R when grown in
the absence of radio-modifying agents.
M. radiodurans, when grown in media containing...
