Palaeoenvironmental evolution of the Tunisian carbonate platform margin
(Univ. Bremen, 2008)
The Late BarremianLate Aptian interval was characterised by several major changes in the ocean/climate system related to the onset of the Mid-Cretaceous greenhouse world. North Africansedimentary deposits offer excellent ...
Antarctic ice sheet expansions in the Middle Miocene and Pliocene
(Univ. Bremen, 2008)
This study focuses on the interactions between climate and ice sheets in order to obtain a better understanding of the processes involved. Two periods in the geological past are explored; the Middle Miocene and the ...
The fate of singularities in quantum cosmology and the application of generalized effective equations to constrained quantum systems
(Univ. Köln, 2009)
The first part of the thesis is concerned with the fate of singularities in quantum cosmology. The second part addresses the derivation of predictions from quantum cosmology. In the first part, two classes of cosmological ...
Methods for the reconstruction of large scale anisotropies of the cosmic ray flux
(Univ. Siegen, 2010)
In cosmic ray experiments the arrival directions, among other properties, of cosmic ray particles from detected air shower events are reconstructed. The question of uniformity in the distribution of arrival directions is ...
Properties of quasistellar objects and their progenitors in the radio and mm wavelength regimes in the context of ULIRG-to-QSO evolution
(Univ. Köln, 2010)
The thesis at hand presents the results of a study of galaxies with active galactic nuclei (AGN) carried out in the radio and mm wavelength regimes at low and high angular resolutions. The studied objects cover a broad ...
Modeling light curves of type Ia supernovae
(Univ. Hamburg, 2009)
The main topic of this work is the introduction of time dependence into PHOENIX. This has been achieved for both the radiation field and the matter in the SN Ia model atmosphere. First, time dependence in the radiative ...
Tectonique et géodynamique actuelle de l'arc alpin
(Univ. Neuchâtel, 2004)
Le régime tectonique actuel de la chaîne des Alpes centrales/occidentales est analysé grâce à une compilation de 389 mécanismes au foyer couvrant l'ensemble de l'arc alpin, ainsi que par l'étude détaillée du séisme de ...
Verbreitung und Eigenschaften von Massenverlagerungsgebieten an der Wellenkalk-Schichtstufe im Thüringer Becken unter besonderer Berücksichtigung geomorphologischer und klimatologischer Steuerungsfaktoren
(Univ. Halle, 2002)
Die Wellenkalk-Schichtstufe im Thüringer ist allgemein als sehr massenverlagerungsanfällig bekannt. Über das großräumige Ausmaß der Massenbewegungen wußte man bislang jedoch nur sehr wenig. Es fehlten Informationen zu ...
Channelised and open-slope processes of mass sediment transport
(Univ. Bremen, 2005)
Sediment transport, high productivity, submarine canyon, submarine slide, excess pore-pressure, weak layers, slope failure. - The study investigates processes of mass sediment transport in two geologically unique Atlantic ...
Macroporosity and Grain Density of Rubble Pile Asteroid (162173) Ryugu
(
- Journal of Geophysical Research: Planets
, 2020-12-04)
Rubble pile asteroids such as (162173) Ryugu have large bulk porosities, which are believed to result from void spaces in between the constituent boulders (macroporosity) as well as void spaces within the boulders themselves ...
