Subcellular localization and characterisation of MAPKs, and cytoskeleton adaptation to stress in Arabidopsis roots
(2009-12-15)
In plants, development and morphogenesis but also adaptation to dynamic environmental changes strongly depend on regulated perception and transmission of stimuli causing a highly specific cellular response. Amongst others, ...
Computational Methods for the Integration of Biological Activity and Chemical Space
(2009-12-14)
One general aim of medicinal chemistry is the understanding of structure-activity relationships of ligands that bind to biological targets. Advances in combinatorial chemistry and biological screening technologies allow ...
Development of high speed integrated circuit for very high resolution timing measurements
(2009-12-07)
A multi-channel high-precision low-power time-to-digital converter application specific integrated circuit for high energy physics applications has been designed and implemented in a 130 nm CMOS process. To reach a target ...
Efficient light transmission through single sub-wavelength holes
(2009-12-09)
The scope of this thesis is to explore two approaches to efficiently address and enhance the transmission of light through sub-wavelength holes in a metal film. In contrast to the often-studied transmission enhancement ...
Niederschlagsbestimmung aus METEOSAT-Second Generation-Zeitreihendaten mit dem Methodenverbund ORFEUSS: Fallbeispiel Namibia
(2009-10-28)
Der Niederschlag ist eines der wichtigsten Parameter im Klimasystem der Erde und bestimmt auf vielfältige Weise unser Leben. Das Wissen über die raumzeitliche Verteilung von Niederschlagsmengen spielt deshalb eine bedeutende ...
Prozessentwicklung zur enzymatischen Synthese chiraler Alkohole unter elektrochemischer Cofaktorregenerierung
(2009-10-22)
Elektroenzymatische Synthesen verbinden die Vorteile zweier nachhaltiger Reaktionskonzepte. Auf der einen Seite wird die Elektrochemie genutzt, um Elektronen als reagenzfreie Reduktionsäquivalente bereitzustellen. Auf der ...
Untersuchungen zur Adhäsionsdynamik migrierender Keratinozyten
(2009-10-19)
Einzelzellen innerhalb eines Gewebes sind über vielfältige Verbindungsstrukturen miteinander verknüpft. Die mechanische Verbindung des Aktin-Zytoskeletts an die extrazelluläre Matrix wird über Proteinkomplexe ermöglicht, ...
High-Quality Simplification and Repair of Polygonal Models
(2009-11-05)
Because of the rapid evolution of 3D acquisition and modelling methods, highly complex and detailed polygonal models with constantly increasing polygon count are used as three-dimensional geometric representations of objects ...
HPLC-IMER as a Fast and Sensitive Method for the Determination of Sulfur Dioxide in Foodstuffs
(2009-10-19)
HPLC-IMER (HPLC with an immobilized enzyme reactor) is a combination of an isocratic HPLC system with an integrated immobilized enzyme reactor and electrochemical detection for the analysis of sulfites. The aim of this ...
Cavitands, Helicates and Macrocycles: Unleashing the Power of Weak Non-Covalent Interactions
(2009-11-12)
In the course of the development of supramolecular chemistry, weak non-covalent interactions have gained tremendous importance. In this work, comprehensive massspectrometric investigations combined with theoretical ...
