Investigating Natural Product Biosynthesis in Uncultivated Symbiotic Bacteria of the Marine Sponge Theonella swinhoei
(2013-01-04)
Marine sponges are a rich source of bioactive natural products with potent anticancer activities. Currently, the limited availability of most of these substances prohibits further drug development (Proksch et al., 2002). ...
Spectral Evolution in Blazars: The Case of CTA 102
(2013-02-05)
Active Galactic Nuclei (AGN) are among the most powerful objects in the universe. In their centre they host a supermassive black hole (BH) with up to 1010 solar masses and an accretion disk is formed around them ...
Analysis of lipid uptake and processing in cultured cells = Lipid-Aufnahme und Stoffwechsel in kultivierten Zellen
(2013-01-28)
To characterize lipid uptake pathways in cultured cells, uptake and metabolism of different isotope-labeled lipid probes were investigated in human skin fibroblasts, a mouse macrophage-like cell line (RAW264.7), human ...
D-Brane Physics: From Weak to Strong Coupling
(2013-03-04)
In this thesis we discuss two aspects of branes relevant to high-energy phenomenology. First, we consider a single D6-brane wrapping a special Lagrangian cycle and the background space compactified in a Calabi-Yau orientifold ......
Management von Arzneimittelinteraktionen in der öffentlichen Apotheke
(2013-02-12)
Ziel: In der vorliegenden Arbeit wurde die Qualität des Interaktionsmanagements in öffentlichen Apotheken bewertet und der Effekt einer Standardarbeitsanweisung (SOP) zum Umgang mit potentiellen Arzneimittelinteraktionen ...
Numerische Simulation von Knochenumbauvorgängen um zahnärztliche Implantate mit der Finite-Elemente-Methode
(2013-01-23)
Zur Untersuchung der Knochenumbauvorgänge sind neben klinischen auch biomechanische Methoden, die den Hauptgegenstand der vorliegenden Arbeit bilden, von besonderer Bedeutung. Insbesondere numerische Simulationen der ...
Electrocatalysis and Kinetics of the Direct Alcohol Fuel Cells: DEMS and ac Voltammetry Studies
(2013-01-23)
The main challenge in the area of fuel cell research is to find a good catalyst that helps in complete oxidation of the fuel at the anode and reduction of the oxygen at the cathode at a low overpotential which consequently ...
Experimentelle Untersuchung molekularer Signalkaskaden in der zellulären Mechanosensorik
(2013-02-19)
Physikalische Signale stellen für Zellen wichtige Informationen dar, die über eine Reihe von Signalkaskaden auf verschiedenste Zellfunktionen wie Zellzyklus, Differenzierung oder Migrationsverhalten wirken. Die von Zellen ...
Factorability, Discrete Morse Theory and a Reformulation of K(π, 1)-conjecture
(2013-02-20)
The first aim of this thesis is to study factorable groups and monoids. We give a new family of examples for factorability structures, provided by Garside theory, in particular, we provide a factorability structure on braid ...
Bottom-up Object Segmentation for Visual Recognition
(2013-03-20)
Automatic recognition and segmentation of objects in images is a central open problem in computer vision. Most previous approaches have pursued either sliding-window object detection or dense classification of overlapping ...
