A simultaneous direct spectrophotometric method for the determination
of barium and strontium using Sulfonazo III has been developed
making use of the chelons EGTA and CDTA at controlled pH
values.
An absorbance study of the barium and strontium complexes of
Sulfonazo III revealed that there is no pH sensitivity of...
The infrared spectra of liquid and solid films of
formaldehyde were taken over the range of 35 to 4,000 cm⁻¹
using Beckman IR 7 and IR 11 spectrometers. A new overtone
band and a new combination band were found as well as three
fundamental peaks due to lattice vibrations and...

A study was undertaken in Yaquina Bay, Oregon during the
summer of 1964 to determine the distribution and the factors affecting
the distribution of the polychaete worm, Nephtys caecoides,
Hartman, 1938, in the estuary.
This organism has a continuous distribution from offshore to
a point approximately eight kilometers into the...
Samples of benthic organisms off the coast of Oregon, taken
from depths varying from 50 to 2900 meters, have been analyzed in
terms of diversity at a given station, and similarity and ecological
distance to other stations. Estimates of epifauna abundance were
also made. In the analysis an important distinction...
Polychaete annelids from 48 benthic samples containing over
2000 specimens were identified. Samples were taken with either an
anchor dredge or an anchor-box dredge from a 15 station transect
(44° 39. 1'N) that ranges from 800 to 2900 meters in depth. Sediment
subsamples were collected and analyzed for organic carbon...
The object of this study was to investigate the possibilities
of inducing superovulation in the chinchilla (Chinchilla lanigera)
by establishing the optimum dosage of pregnant mares' serum (PMS)
to produce a maximum ovulatory response, and to compare chinchilla
with other animals in this respect. Non-pregnant female chinchillas
were given a...
