Seemayer, Andreas (2009-09-03)Oberflächencharakterisierung von III-V MOCVD-Filmen aus heterozyklischen Single Source Precursoren In vielen mikro- und optoelektronischen Bauteilen finden Antimon-haltige Verbindungshalbleiter Verwendung. Insbesondere ist ... -
Oberflächenmodifizierung von Lactose mit überkritischem CO2
Gericke, Sabrina (2003)In der pharmazeutischen Industrie gewinnen die Mikronisierung und die Oberflächenbehandlung mit überkritischen Fluiden immer mehr an Bedeutung. <br /> Ein Stoff wird zum überkritischen Fluid, wenn Druck und Temperatur über ... -
Objective and quantitative methods in the study of dinosaur tracks
Lallensack, Jens Nikolaus (2019-02-05)This dissertation develops and employs objective and quantitative methods for the analysis of dinosaur tracks. Tracks are—besides the familiar bones and teeth—a crucial data source for inferences on dinosaur biology and ... -
Observation of top quark pair production and estimation of W+jets background with ATLAS at the LHC
Radics, Bálint (2010-12-22)An analysis has been presented based on an integrated luminosity of 2.9 pb<sup>-1</sup> of 7 TeV center-of-mass energy proton-proton collision data in ATLAS at the Large Hadron Collider. The data have been collected since ... -
Observation of W → τντ Decays with the ATLAS Experiment
Nunes Hanninger, Guilherme (2011-05-04)Physics studies of processes with t leptons in the final state, while challenging at hadron colliders, are of great importance at the LHC. The τ leptons provide important signatures in searches for the Higgs boson as well ... -
Observations of the Sunyaev-Zel'dovich Effect towards Clusters of Galaxies with the APEX Telescope
Nord, Martin (2009-09-14)Results of 150 GHz continuum observations of several X-ray bright clusters of galaxies in the Sunyaev-Zel'dovich (SZ) effect, carried out using the APEX-SZ bolometer array on the APEX telescope, are presented. Follow-up ... -
Obstruction theory for operadic algebras
Dimitrova, Boryana (2012-05-21)We study obstruction theory for formality of chain operadic algebras. We construct a canonical class γ<sub>A</sub> for an algebra A over a cofibrant chain operad P<sub>∞</sub>. This class takes values in the Gamma cohomology ... -
Occlusion and Function of Triconodont Dentitions
Jäger, Kai Richard Kurt (2020-12-18)Over the last decades, many studies have focused on the tribosphenic molar and its functional aspects because it is considered to be a key innovation in mammalian evolution. Early triconodont dentitions have been examined ... -
Ocular Onchocerciasis: The Role of Toll-Like Receptor-2 and Interferon-γ
Gentil, Katrin (2010-03-17)River Blindness is still highly prevalent in subsaharan Africa with millions of people suffering from the infection with <i>Onchocerca volvulus</i>. This filarial worm harbors the endosymbiont <i>Wolbachia</i> which was ... -
Odor-evoked modulation of the olfactory bulb by projections from the horizontal limb of the diagonal band of Broca
Müller, Monika (2021-07-09)Olfactory input encodes essential information about the environment and shapes adapted behavioral reactions. Hence, the olfactory system is complex with diverse brain areas processing the sensory input on different levels. ... -
Off-Label-Use von Arzneimitteln in der Palliativmedizin
Hafner, Katrin (2013-05-07)Es steht außer Frage, dass die gesundheitliche Versorgung unserer Gesellschaft durch den medizinischen Fortschritt in den letzten Jahrzehnten enorm gesteigert wurde. Dabei ist der Schwerpunkt dieser Entwicklung auf Heilung ... -
Old Globular Clusters in Dwarf Irregular Galaxies
Georgiev, Iskren Y. (2008)<p>One of the most pressing questions in astrophysics to date is resolving the history of galaxy assembly and their subsequent evolution. In the currently popular hierarchical merging” scenario, massive galaxies are believed ... -
Oligozäne Beckendynamik und Sequenzstratigraphie am Südrand des Nordwesteuropäischen Tertiärbeckens
