Superconducting hot electron bolometers on silicon nitride membranes for terahertz waveguide mixers
(Univ. Köln, 2004)The topic of this work is the development of Hot Electron Bolometer (HEB) mixers on freestanding membrane substrates for terahertz high resolution heterodyne receiver systems. The radio astronomy in the THz frequency ... -
Supernova remnants in nearby galaxies
(Astronomische Nachrichten, 2020)Supernova remnants (SNRs) are the aftermath of stellar explosions, which inject large amounts of energy into the interstellar medium (ISM), carving out new structures and transferring kinetic energy to the ISM. They also ... -
Supernova-driven turbulence and magnetic field amplification in disk galaxies
(Univ. Potsdam, 2009)Supernovae are known to be the dominant energy source for driving turbulence in the interstellar medium. Yet, their effect on magnetic field amplification in spiral galaxies is still poorly understood. Analytical models ... -
Suprathermal Fe in the Earth's Plasma Environment: Cluster RAPID Observations
(Journal of Geophysical Research: Space Physics, 2020)Baryonic matter in geospace is almost exclusively in a plasma state, with protons (H +) and to some extent ionized helium (He) and oxygen (O) being the dominant ion species. But also other heavier ion species and even ... -
Surface exposure dating with cosmogenic nuclides
(E&G – Quaternary Science Journal; Vol.57, No. 1-2)Im letzten Jahrzehnt hat sich die Methode der Oberflächendatierung mittels kosmogener Nuklide zu einer leistungsfähigen Methode in der Quartärchronologie und quantitativen Landschaftsanalyse entwickelt. Kosmogene Nuklide ... -
Surface geometry of the Last Glacial Maximum (LGM) in the southeastern Swiss Alps (Graubünden) and its paleoclimatological significance
(E&G – Quaternary Science Journal; Vol.48, No. 1)Anhand detaillierter Feldbefunde, wie z.B. Schliffgrenzen an ehemaligen Nunatakern, der Verteilung erratischer Blöcke und der Orientierung von Gletscherschrammen, wurde die Oberflächengeometrie des Akkumulationsgebietes ... -
Surface properties of asteroids from mid-infrared observations and thermophysical modeling
(Univ. Berlin, 2007)The subject of this work is the physical characterization of asteroids, with an emphasis on the thermal inertia of near-Earth asteroids (NEAs). Thermal inertia governs the Yarkovsky effect, a non-gravitational force which ... -
Surface spots on cool giant stars probed by spectro-astrometry
(Univ. Hamburg, 2009)Spectro-astrometry is a technique to obtain information about the structure of an astronomical source on sub-diffraction limited spatial scales down to milli- or micro-arcseconds. The method exploits the shift of the ... -
Surface velocity fields of active rock glaciers and ice‐debris complexes in the Central Andes of Argentina
(Earth Surface Processes and Landforms, 2020-12-30)Rock glaciers and transitional ice‐debris complexes predominate the Central Andean landform assemblage, yet regional studies on their state of activity and their kinematics remain sparse. Here we utilize the national glacier ... -
Surface Wave and Roller Dissipation Observed With Shore‐Based Doppler Marine Radar
(Journal of Geophysical Research: Oceans, 2022-08-24)Surface wave energy and dissipation are observed across the surf zone. Utilizing the concept of surface rollers, a new scaling is introduced to obtain the energy flux and dissipation related to rollers from Doppler velocities ... -
“Surface,” “satellite” or “simulation”: Mapping intra-urban microclimate variability in a desert city
(International Journal of Climatology, 2019)Mapping spatial and temporal variability of urban microclimate is pivotal for an accurate estimation of the ever-increasing exposure of urbanized humanity to global warming. This particularly concerns cities in arid/semi-arid ... -
Surwold und Freising: - Erste sektorübergreifende Ansätze zur Definition einer nachhaltigen Moornutzung
(TELMA - Berichte der Deutschen Gesellschaft für Moor- und Torfkunde; Beiheft 6; 2020) -
Sustainability impact assessment of peatland-use scenarios: Confronting land use supply with demand
(Ecosystem Services, 2017)Sustainable development of land use is determined by changes of the regional supply of Land Use Functions (LUFs) and the demand of future societal land use claims. LUFs are based on the ecosystem services concept, but ... -
Sustainable Cathodes for Lithium‐Ion Energy Storage Devices Based on Tannic Acid—Toward Ecofriendly Energy Storage
(Advanced Sustainable Systems, 2020-11-18)The use of organic materials with reversible redox activity holds enormous potential for next‐generation Li‐ion energy storage devices. Yet, most candidates are not truly sustainable, i.e., not derived from renewable ... -
Sustainable research software for high-quality computational research in the Earth System Sciences: Recommendations for universities, funders and the scientific community in Germany
(2023)Similar to other research fields, new knowledge in the Earth System Sciences is increasingly produced by computational research. However, the reproducibility of this type of research has been shown to be very limited, and ... -
Sustaining Saturn's Electron Radiation Belts Through Episodic, Global-Scale Relativistic Electron Flux Enhancements
(Journal of Geophysical Research: Space Physics, 2020)The L shell distributions of MeV electrons in Saturn's radiation belt are investigated orbit by orbit for the 13-year exploration of Cassini. It is found that in addition to the monotonic decrease profiles, there are orbits ... -
Südwest-Afrika - Böden und Bodenkultur ; Versuch einer Klimapedologie warmer Trockengebiete
