Untersuchungen zur Funktion der alpha-hydroxylierten Sphingolipide im Nervensystem und in der Haut
(2009-08-26)
Das Myelin von Säugetieren enthält große Mengen α-hydroxylierter Glykosphingolipide, deren Funktion unklar ist. Bislang konnte nur ein murines Enzym identifiziert werden, das vermutlich für die α-Hydroxylierung der ...
Variability studies of a sample of IntraDay Variable sources
(2009-07-07)
The discovery of IntraDay Variability (IDV) in the radio flux from Active Galactic Nuclei gave rise to a series of fundamental issues concerning the origin of the variability. The observation of large flux-density variations ...
Three-Body Halo Nuclei in an Effective Theory Framework
(2009-07-02)
The universal properties and structure of halo nuclei composed of two neutrons (2n) and a core are investigated within an effective quantum mechanics framework. We construct an effective interaction potential that ...
Enantiomerentrennung von Polyphenolen mittels Kapillarelektrophorese
(2009-06-29)
In der vorliegenden Arbeit werden Ergebnisse zur Untersuchung von phenolischen Pflanzeninhaltsstoffen (enantiomere Polyphenole) mittels enantioselektiver Kapillarelektrophorese vorgestellt. Die untersuchten Analyten stammen ...
Methods for Computer-Aided Chemical Biology: Exploration of Compound Selectivity
(2009-07-03)
Computational drug design and discovery methods have traditionally put much emphasis on the identification of novel active compounds and the optimization of their potency. For chemical genetics and genomics applications, ...
Hodge classes on self-products of K3 surfaces
(2009-07-03)
This thesis consists of four parts which investigate different aspects of Hodge classes on self-products of K3 surfaces.
In the first three parts we present three different strategies to tackle the Hodge conjecture ...

Can resilience be built through micro-finance tools?: A case study of coping and adaptation strategies to climate-related shocks in Piura, Peru
(2009-07-07)
This study focuses on the livelihoods of rural households in the region of Piura in northern Peru, who are either farmers or livestock holders. The livelihood systems of these farmers are exposed to and vulnerable to ...
The role of guanine nucleotide exchange factors in the regulation of immune cell signaling
(2009-07-08)
The ARF GEF cytohesin-1 was originally identified as β2-integrin binding protein, and was shown to play an important role in the control of integrin-dependent immune cell migration and adhesion via activating the small ...
A Multigrid Method for the Efficient Numerical Solution of Optimization Problems Constrained by Partial Differential Equations
(2009-05-25)
We study the minimization of a quadratic functional subject to constraints given by a linear or semilinear elliptic partial differential equation with distributed control. Further, pointwise inequality constraints on the ...
Der Einfluss des Geschlechtshormons Östrogen auf die elektromechanische Kopplung des Herzens
(2009-07-21)
Im Rahmen dieser Arbeit wurde der Einfluss des Geschlechtshormons Östrogen auf die elektromechanische Kopplung von Herzmuskelzellen bestimmt. Ziel dieser Studie war es, Kenntnisse über die genauen physiologischen Abläufe ...
