Nachweis des Europäischen Waldelefanten Elephas antiquus (Falconer & Cautley, 1847) bei Neubrandenburg in Mecklenburg-Vorpommern (NE-Deutschland) - Fundbericht
(Neubrandenburger Geologische Beiträge, 2012-04-17)Funde von pleistozänen Großsäugern sind in Mecklenburg-Vorpommern (NE-Deutschland) wegen der starken Dominanz glazigener Sedimente mit ungünstigem Erhaltungspotential vergleichsweise selten (Benecke 2002, Meng et al. 2010). ... -
Nanoscale Metallic Iron for Environmental Remediation: Prospects and Limitations

NanoSIMS analysis and high resolution electron microscopy of silicate stardust grains from red giant stars and supernova explosions
(Univ. Frankfurt (Main), 2009)This thesis deals with the analysis of presolar silicates and oxides by high resolution mass spectrometry and electron microscopy techniques. This stardust was identified by its extreme oxygen isotopic anomalies, which ... -
The narrow line region of active galaxies
(Univ. Bochum, 2005)This thesis presents an imaging and spectroscopic study of the narrow-line region (NLR) in active galactic nuclei (AGNs). We find a correlation between size and luminosity of the NLR with different slopes for type-1 and ... -

(Berliner Geographische Blätter; 9) -
Natur erleben und Raum inszenieren
(Universtätsverlag Göttingen, 2008)Sowohl private als auch öffentliche Akteure widmen sich der Inszenierung von Naturerlebnisangeboten. Die Vielfalt an thematischen Inhalten, didaktischen Konzepten und Zielgruppen sorgt dafür, dass der Begriff Naturerleben’ ... -
Natural building stones of Mexico–Tenochtitlán: their use, weathering and rock properties at the Templo Mayor, Palace Heras Soto and the Metropolitan Cathedral
(Environmental Earth Sciences, 2011)In the Aztec period and in colonial times different natural stones originating in the Valley of Mexico were used for building construction. Stone weathering was investigated onsite at various historical buildings within ... -
Natural resource degradation and famine in Ethiopia - assessment of students' awareness and views

Natural variability or anthropogenically-induced variation? Insights from 15 years of multidisciplinary observations at the arctic marine LTER site HAUSGARTEN
(Ecological Indicators, 2016)Time-series studies of arctic marine ecosystems are rare. This is not surprising since polar regions arelargely only accessible by means of expensive modern infrastructure and instrumentation. In 1999, theAlfred Wegener ... -

Naturschutzorientierte Flachabtorfungen in Kalkflachmooren – ein Erfahrungsbericht aus Nord-Brandenburg
(TELMA - Berichte der Deutschen Gesellschaft für Moor- und Torfkunde, 2009)Abstract: The natural park „Uckermärkische Seen“ is outstanding due to precious brownmoss dominated calcareous fens. None of them are undisturbed or virgin. Even in the remote areas of northern Brandenburg peatlands ... -
Nd–Sr–Hf–O isotope provinciality in the northernmost Arabian–Nubian Shield: implications for crustal evolution
(Contributions to Mineralogy and Petrology, 2009)Multi-isotope study including whole-rock Nd–Sr, single zircon Hf, and SIMS δ18O analyses of zircons sheds light on magma sources in the northernmost Arabian–Nubian Shield (ANS) during ~820–570 Ma. Reconnaissance initial ... -
The near infrared activity of Sagittarius A*
(Univ. Köln, 2008)The meaning of my thesis was to obtain new insights about the supermassive Black Hole in the center of our Milky Way and its accretion flow. The non-thermal radio, X-ray, and near-infrared source Sagittarius A* (Sgr A*) ... -
Near- and mid-infrared studies of the galactic center and Sagittarius A*
(Univ. Köln, 2007)The focus of this thesis lies on the analysis and interpretation of near- and mid-infrared images of the Galactic center, with a view to improving the understanding of this region, especially at longer wavelengths. Multi-band ... -
Near-surface sediment structures at cold seeps and their physical control on seepage - a geophysical and geological study in the southern Gulf of Mexico and at the frontal Makran Accretionary prism, Pakistan
(Univ. Bremen, 2009)The major objective of the study is to investigate how near-surface sediment structures and other geological aspects control the nature and occurrence of cold fluid seepage. Mainly high resolution multichannel seismic data ... -
Neogene seismotectonics of the south-central Chile margin - subduction-related processes over various temporal and spatial scales
(Univ. Potsdam, 2007)The Andean orogen is the most outstanding example of mountain building caused by the subduction of oceanic below continental lithosphere. The Andes formed by the subduction of the Nazca and Antarctic oceanic plates under ... -
