TL;DR: In the 15-day-old chick embryo, the antimitotic effect was tissue specific in that only hepatocytes and not control tissues had depressed mitotic indices, consistent with the presence of a G2—M blocking factor.

TL;DR: A deep sea recording capsule carrying two quartzcrystal pressure sensors and two quartz-crystal temperature sensors was operated in 2.2 km depth off Brest during November-December 1973 as part of an inter national deep sea tide gauge intercalibration experiment as discussed by the authors.
Abstract: A deep sea recording capsule carrying two quartz-crystal pressure sensors and two quartz-crystal temperature sensors was operated in 2.2 km depth off Brest during November-December 1973 as part of an inter national deep sea tide gauge intercalibration experiment. The dual instrumentation provides information for in situ evaluation of instrument calibrations. Differences in the recordings give estimates of the instrumental noise spectra. Instrumental noise of the temperature-corrected pressure sensor was found to be 10-20 db below the sea level continuum spectrum at frequencies below 0.2 cph. At higher frequencies the pressure signal-to-noise ratio decreased to 0-6 db at 3 cph (the Nyquist). The temperature sensor noise spectrum was everywhere 20-40 db below the signal spectrum. Problems associated with using dual instrumentation to evaluate sensor performance are discussed.
