Synthesis of total RNA, DNA, and protein was followed in a
haploid yeast auxotroph during starvation for required amino acids
and uracil, and during shift-up and shift-down conditions.
During amino acid starvation, synthesis of macromolecular
constituents was not immediately affected, reflecting the presence
of large intracellular amino acid pools. Under...
An experimental study has been made of the local natural convective
heat transfer coefficient around the circumference of a heated
horizontal cylinder oscillating vertically in water. The heat transfer
surface consisted of a 1 3/8-inch diameter cylinder with a small test
section imbedded in its surface. This enabled data to...
Assay conditions and analytical methods established for the
study of epoxidation of the insecticides aldrin and heptachlor, by
rat liver microsomes have been employed to study the same reaction
catalyzed by trout liver microsomes. At 37° C and pH 8.0, rainbow
trout liver microsomes, incubated with 54.8 millimicromoles of
either...
The character of the primary seismic wave in the
range of distances between 100 and 600 km is affected by
such factors as the nature of the source, exponential
attenuation, crustal structure, type of wave propagation,
recording site geology and instrument response. The
first arrivals from the GNOME and SHOAL...
Opossum shrimp Mysis relicta were collected in Upper Waterton Lake, Alberta, Canada, in the summer of 1966 for the second successive year. Approximately 650,000 were collected and introduced into Waldo, Wallowa, Big Cultus, Crescent, and Timothy Lakes in Oregon.
The Opossum shrimp Mysis relicta were collected in Upper Waterton Lake, Alberta, Canada in late August and early September 1965. Approximately 320,000 shrimp were introduced into Waldo, Wallowa, Big Cultus and Timothy Lakes in Oregon.
Opossum shrimp, Mysis relicta Loven, were collected at Upper Waterton Lake, Alberta, Canada in the summer of 1967, terminating a three-year project. Approximately 1,090,000 Mysis were transplanted into Big Cultus, Crescent, Detroit, Fourmile, Ice, Miller, Odell, Olive, Timothy, Waldo, and Wallowa Lakes in an attempt to enhance the quantity of...
This report is a description of the first extended oceanographic
cruise made by staff of the Department of Oceanography, Oregon State
University, aboard the Research Vessel YAQUINA. The purpose is to
describe the track made good and the observational programs undertaken
for the information of those who may wish to...
