    Ein frühpleistozänes Kalkartefakt von Würzburg-Schalksberg (2011)
    Geozon Science Media
    Details
    Publication Date: 2021-03-29
    Description: In den Jahren 1966 und 1976 wurden bei Ausschachtungsarbeiten in Würzburg-Schalksberg zahlreiche mauerzeitliche Faunenreste aus alten Ablagerungen des Mains geborgen. Zusammen mit den nichtumgelagerten, z.T. bearbeiteten Knochen wurden Werkzeuge aus Kalk entdeckt, die in altpleistozäner Technik hergestellt wurden.

    Über neue Artefaktfunde aus der Heidelberger Stufe (2011)
    Geozon Science Media
    Details
    Publication Date: 2021-03-29
    Description: Nach der Entdeckung altpleistozäner Artefakte der Heidelberger Stufe in Norddeutschland und bei Mauer ließ sich der erkennbare Lebensraum des Homo heidelbergensis jetzt wesentlich ausweiten. Neue Funde aus den präglazialen Terrassen von Süssenborn bei Weimar erwiesen eine Besiedlung auch Mitteldeutschlands, und gleichartige Funde aus den ältesten Donauterrassen bei Wien werden als Hinweis auf eine weitgehend nach Osten in den Kontinent hineinreichende Besiedlung durch den Heidelberger Menschen aufgefaßt. Artefaktfunde aus den Rheinschottern bei Brüggen führen an die plio-pleistozäne Grenze. Im Nachtrag werden Heidelberger Artefakte aus den oberpliozänen Schottern von Sülzfeld in Thüringen angeführt, die den Artefakten von Mauer typologisch sehr nahestehen.

    Zur relativen und absoluten Geochronologie der Reliefentwicklung an der Küste des mittleren Südwestafrika (2011)
    Geozon Science Media
    Details
    Publication Date: 2021-03-29
    Description: Ergebnisse quartärgeomorphologischer Arbeiten an der Namibküste werden präsentiert. Dort lassen sich zwei Meereshochstände, ein Meerestiefstand nachweisen. Der jüngere Meereshochstand ist nach l4C-Datierungen ins Innerwürm zu stellen (ca. 26 000 B.P.). Er ist eindeutig eustatisch. Jungquartäre Vertikaltektonik im Küstenbereich ist nicht auszuschließen. Die zeitlichen Änderungen des Meeresspiegels werden mit Phasen der terrestrischen Morphogenese verknüpft. Meereshochstände korrelieren mit „trockenen", Meerestiefstände mit „feuchten" „Klima"-Bedingungen.

    The Stable Solar Analyzer (1988)
    In:  CASI
    Details
    Publication Date: 2019-06-28
    Description: Progress in the development of an instrument with very high (1:10 billion) wavelength stability designed to measure solar surface velocities and magnetic fields is reported. The instrument determines Doppler and Zeeman shifts in solar spectral lines by a 6-point weighted average. It is built around an electrically tunable solid lithium-niobate Fabry-Perot etalon that is stabilized against a diode laser which itself is locked to a resonance line of cesium 133. Key features are the etalon, which acts as a wide-angle 0.017-nm solar filter, the camera with a specially stabilized shutter, and the instrument control and data collection system. Use of the instrument in helioseismological research is emphasized.

    Some design considerations for a satellite-borne magnetograph (1985)
    In:  CASI
    Details
    Publication Date: 2019-06-28
    Description: The design criteria for a compact magnetograph that can monitor solar magnetic fields from a free-flying satellite for 5 to 10 years are reviewed. The signal-to-noise ratio that can be obtained with a 10-cm f/10 refractor operated with a Fabry-Perot filter and a solid-state detector array is derived. The telescope measures the longitudinal component of the magnetic field for the entire solar disk in a few minutes at a 20-G threshold and at 3-arcsec resolution. The Fabry-Perot filter has a lithium niobate etalon, which can be tuned electrically and operated at a fixed tilt angle in such a manner that it cancels the solar rotational Doppler shifts in the transmitted spectrum. Principles of operation of various types of polarization modulators are presented, and it is concluded that photoelastic modulators and liquid-crystal devices hold the most promise for use in a satellite-borne magnetograph,

    A tunable, solid, Fabry-Perot etalon for solar seismology (1986)
    In:  Other Sources
    Details
    Publication Date: 2019-06-28
    Description: A solid etalon has been designed and fabricated from a 50-mm diameter wafer of optical-quality lithium niobate. The finished etalon has a free spectral range of 0.325 nm at 588 nm. The parallel faces are coated with silver, and the central 15-mm aperture of the etalon has a finesse of 18.6. The reflective faces double as electrodes, and application of voltage will shift the passband. This feature was used in a servo circuit to stabilize the passband against temperature and tilt-induced drifts to better than three parts in one billion. Operated in the stabilized mode for day-long sessions, this filter alternately samples the wings of a narrow atomic absorption line in the solar spectrum and produces a signal proportional to velocity on the solar disk. The Fourier transform of this signal yields information on acoustic waves in the solar interior.

    A photoelectric technique for measuring lightning-channel propagation velocities from a mobile laboratory (1989)
    In:  Other Sources
    Details
    Publication Date: 2019-07-12
    Description: The present device for lightning channel propagation-velocity determination employs eight photodetectors mounted behind precision horizontal slits in the focal plane of a photographic camera lens. The eight photodetector pulses, IRIG-B time, and slow and fast electric field-change waveforms are recorded on a 14-track analog tape recorder. A comparison of the present results with those obtained by a streaking camera shows no significant differences between the velocities obtained from the same strokes with the two systems; neither is there any difference in pulse characteristics or in the velocities calculated from them.
