Jets from Spinning Black Holes in Active Galactic Nuclei
(2011-02-08)
Relativistic jets are highly collimated plasma outflows that can be present in extragalactic radio sources, which are associated with active galactic nuclei (AGN). Observations give strong support for the idea that a ...
Schwingungsdynamik von intra- und intermolekularen Wasserstoffbrückenbindungen
(2011-02-10)
Die Dynamik intramolekularer Wasserstoffbrückenbindungen (H-Brückenbindungen) wird in dieser Arbeit anhand stereoselektiv synthetisierter Polyole in unpolaren Lösungsmitteln mit zwei, vier und sechs Hydroxylgruppen untersucht. ...
Synthese von π-konjugierten Oligomeren und deren Selbstorganisation zu Nanoaggregaten
(2011-01-28)
Oligo-p-phenylene sind organische Bausteine, die durch Aufdampfen auf feste Substrate in der Lage sind, Nanoaggregate zu bilden. Diese Strukturen können Längen von bis zu einem Millimeter erreichen und zeigen außerdem eine ...
Analysis of pixel systematics and space point reconstruction with DEPFET PXD5 matrices using high energy beam test data
(2011-03-04)
To answer the current questions in particle physics vertex-detectors, the innermost sub-detector system of a multipurpose particle detector, with brilliant spatial resolution and at the same time with as little sensor ...
Biogeographical Analyses and Applications: The Study of Plant Distribution Patterns in West Africa
(2011-03-10)
Studies and applications in biogeography aim at understanding the causes and determinants of past, current, and future diversity distribution patterns. In this context, niche models are currently important tools. They make ...
Towards single atom aided probing of an ultracold quantum gas
(2011-03-01)
In this thesis, the interactions in an unbalanced Rubidium (Rb)-Caesium (Cs) mixture are studied, where the Cs atoms have been used as probes to study the interspecies interactions. The Rb atoms are trapped and stored in ...
Wechselwirkung zwischen Ultraschall & Proton-Spin in wässriger Lösung
(2011-03-16)
Die Suche nach einem Einfluss von Ultraschall auf das Kernspinsystem in weicher Materie ist eine spannende Aufgabe. Nachdem in den 50er Jahren gezeigt werden konnte, dass in homogenen Flüssigkeiten die hohe Moleküldynamik ...
Real-Time Markerless Tracking the Human Hands for 3D Interaction
(2011-02-18)
This thesis presents methods for enabling suitable human computer interaction using only movements of the bare human hands in free space. This kind of interaction is natural and intuitive, particularly because actions ...
Novel Secondary Metabolites from Endophytic Marine-derived Fungi
(2011-02-22)
The marine environment is distinguished by unique groups of organisms being the source of a wide array of fascinating structures. Marine microorganisms, such as fungi often occur associated with macroorganisms like algae, ...
The Human Adenosine A2B Receptor: Homology Modeling, Virtual Screening, and Computer-aided Drug Design
(2011-02-10)
The adenosine A2B receptor belongs to the class A of G protein-coupled receptors. It is playing a crucial role in cell signalling and various physiological responses. The adenosine A2B receptor, a ...
