    Description / Table of Contents: Zusammenfassung Ein elektronischer Schallspektrograph wurde benutzt, um die nichtstationären Vorgänge in komplizierten Erdbeben- und Explosionswellen zu analysieren. Die Analyse von nichtstationären Vorgängen mittels dieses Schallspektrographen ergibt unmittelbar die Gruppengeschwindigkeit jeder einzelnen Spektralfrequenz für die verschiedenen seismischen Wellenphasen, die ja solche nichtstationären Vorgänge darstellen. Verglichen mit einer gewöhnlichen Frequenzanalyse liefert diese Art von Analyse die Spektralfeinstruktur des zeitlich sich ändernden Signals und nicht ein Mittel über ein Zeitintervall, das einen grösseren Teil des seismischen Schwingungsablaufs umfasst. Sowohl Dispersionserscheinungen in derP-Welle als auch deren diskretes Amplitudenspektrum wurden mit Hilfe dieser Analyse seismischer Signale festgestellt. Dispersion wurde mit ziemlicher Wahrscheinlichkeit auch bei derS-Welle beobachtet, und in den verschiedenen mehrfachreflektiertenS-Wellen zeigt sich in aufeinanderfolgenden Reflexionen eine Periodenzunahme. Das disperse Erscheinungsbild der Oberflächenwellen in ihrer Grundschwingungstype und den zugehörigen Schwingungstypen höherer Ordnung wurde für ozeanischen, kontinentalen und gemischten Weg aufgenommen. Unter diesen Wellentypen findet sich eine klare Andeutung der kontinentalen Scherschwingungsform zweiter Ordnung vom Rayleigh-Typus (Second Shear Mode). Die Aufspaltung von Oberflächenwellen für direkten und antipodalen Weg wurde ebenfalls erreicht. Unsere Ergebnisse zeigen eine gute Übereinstimmung mit den von herkömmlichen Methoden stammenden Resultaten. Die Dispersion von Wellentypen erster und höherer Ordnung, die durch Explosionen im Seichtwasser angeregt werden, kann leicht an Hand der Schallspektrogramme und momentanen Amplitudenspektren ihrer seismischen Signale untersucht werden. Solche Seichtwasserdetonationen zeigen Pulsationen und Airy-Phasen, die sich eindeutig auf den Spektrogrammen und Amplitudenbildern abzeichnen.
    Notes: Summary An electronic sound spectrograph has been used to analyze the transients in complicated earthquake and explosion signals. Transient analysis with a sound spectrograph gives a means for directly obtaining group velocity at each of the spectral frequencies for each of the separate arrival branches, for any type of transient signal. Compared to frequency analysis, it presents the fine spectral structure of the signal as it changes with time, not an average over a time that includes many parts of the seismic signal. Dispersion as well as the body wave spectrum of theP wave has been observed by transient analysis of seismic signals. Dispersion has also possibly been observed in theS wave, and in the various multiply reflectedS waves, which have been found to increase in period from one arrival to the next. The dispersed pattern of arrival of fundamental and higher mode surface waves has been observed for oceanic, continental, and mixed paths. Among these signals is a clear indication of the continental second shear mode. The separation of surface waves for the direct and complementary paths has also been accomplished. Our results compare well with those obtained by standard techniques. The dispersion of the fundamental and higher mode signals from explosive sources in shallow water may be easily studied by making sound spectrograms and amplitude sections of these seismic signals. These shallow water shots show bubble pulses and Airy phases, which are clearly defined on the spectrograms and sections.

    Description / Table of Contents: Zusammenfassung Magnetbandaufzeichnungen von Erdbebensignalen können, mit vervielfachter Geschwindigkeit wiedergegeben, mittels eines elektronischen Schallspektrographen analysiert werden. Das zeitabhängige Raumwellenspektrum, das man aus einer solchen Analyse nichtstationärer Vorgänge erhält, gibt einen gewissen Einblick in die physikalischen Eigenschaften des Erdinnern. So wurde im kurzperiodischen Anteil der Raumwellen, die durch den äusseren und inneren Erdkern gelaufen sind, Dispersion beobachtet. BeiP′ wurde im Periodenbereich zwischen 1 und 2 Sekunden ein Gruppengeschwindigkeitsmaximum gefunden. Der direkte StrahlP′ und die einmal an der Erdoberfläche reflektiertePP-Welle transportieren mehr Energie als die WellenphasenP′ 2 undPcPP′, die erstens in den äusseren Erdkern unter einem sehr grossen Inzidenzwinkel eindringen und zweitens eine längere Zeit benötigen, um den äusseren Teil des flüssigkeitsähnlichen Kerns zu durchlaufen.
    Notes: Summary Speeded-up magnetic tape recordings of earthquake signals can be analyzed by means of an electronic sound spectrograph. The time-dependent spectrum of body waves obtained through transient analysis provides some insight into the physical properties of the earth's interior. In the short-period arrivals traveling through the outer core and inner core dispersion has been observed. A group velocity maximum has been found forP′ at periods between 1 and 2 seconds. The direct rayP′and the surface reflected phasePP convey more energy than the arrivalsP′ 2 andPcPP′ which, firstly, enter the outer core at incidence far from vertical, and secondly spend more time in the outer part of the fluid core.

    Notes: An apparatus is described that exploits the high precision of a spherical resonator in the temperature range 80 to 350 K at pressures up to 1.3 MPa. We have used the radial modes of the spherical resonator to measure the speed and absorption of sound in CF4 in the temperature range 175 to 300 K and the pressure range 0.08 to 1.0 MPa. The speeds of sound, which have a precision better than 0.001% have been used to obtain perfect-gas heat capacities and second and third acoustic virial coefficients of CF4. (p,V,T) virial coefficients calculated from the results are in good agreement with those in the literature. We also report vibrational relaxation times for CF4 determined from the linewidths of the radial modes.

    Notes: All core evidence supports the conclusion that abyssal plains are sites of graded-bed sequences deposited from turbidity flows. The deposits appear to be present-day equivalents of thin- to medium-bedded, graded, flysch-type sands and silts of many ancient geosynclines and sedimentary basins.

    Notes: The northeast corner of the Pacific Ocean is a region of turbidity-current activity. Cores from this area are dominated by very fine-grained sand and medium-grained silt that grade upward to clay. The results presented in this article are based on 217 textural analyses of turbidite layers comprising 30 piston cores.It is possible to distinguish proximal and distal facies of turbidites using characteristics of layering, grading and texture. Features of the proximal facies include wide range of layer thickness, maximum layer thickness, non-grading, truncation of grading, textural reversals, and sand at the base of graded layers. Areas beyond main routes of submarine flows are sites of episodic addition of silt-through clay-sized sediment. The proportion, thickness, and mean grain size of the silt decreases with increasing distance from the main avenues of flow.

    Identification and characterization of mitochondrial translation products in various yeasts and inPrototheca zopfii (1985)

    Notes: Summary Mitochondrial genomes of different eucaryotes are not all alike. We have examined mitochondrial translation products in a number of yeasts (Candida krusei, Hansenula saturnus, Rhodotorula glutinis, Rhodotorula rubra, Torulopsis glabrata andSaccharomyces cerevisiae) and in Prototheca zopfii, a colorless alga, in order to determine whether certain proteins are invariably synthesized within mitochondria, how different these proteins are, and what additional proteins, if any, might be synthesized by diverse mitochondria. Using a variety of techniques and criteria, including immunological analysis and peptide mapping, we show that all the yeasts studied, and probablyP. zopfii as well, make versions of the 3 large subunits of cytochrome c oxidase. Not all of these oxidase subunits are equally closely related to their counterparts inS. cerevisiae, however. Mitochondria of some of the yeasts studied do not make, or make only small amounts of, a counterpart to Varl, a major mitochondrially made protein inS. cerevisiae. Mitochondria ofP. zopfii possibly do not make an apocytochrome b.T. glabrata, H. saturnus and the two Rhodotorula species each make one or more proteins whose relationship, if any, to mitochondrial translation products ofS. cerevisiae is not apparent. These results provide new information about mitochondrial diversity. Whereas mitochondria of all the organisms that we have studied devote the major part of their synthetic effort to making the three large subunits of cytochrome c oxidase, and probably make certain other proteins in common, they do not all synthesize a completely identical set of proteins.
