Untersuchungen zur Rolle der ZIPK und der Bedeutung der Histon H3-Thr11-Phosphorylierung in der Mitose
(2009-01-29)
Die ZIPK ist eine Serin/Threonin-Kinase die in verschiedene zelluläre Prozesse, wie die Regulation der Transkription, Zellmotilität, Apoptose und Mitose involviert ist. Die vorliegende Arbeit befasste sich mit zwei Aspekten. ...
Regulation und funktionelle Bedeutung der Arginase und Arginase-abhängiger Stoffwechselwege in Atemwegszellen der Ratte
(2009-01-20)
Das Enzym Arginase, besonders die Isoform Arginase I, ist klassischerweise ein Enzym des Harnstoffzyklus, der seine Bedeutung in der Entgiftung von Ammoniak in der Leber findet. In zahlreichen extrahepatischen Zellen und ...
On Dynamic Coherent and Convex Risk Measures: Risk Optimal Behavior and Information Gains
(2009-08-27)
We consider tangible economic problems for agents assessing risk by virtue of dynamic coherent and convex risk measures or, equivalently, utility in terms of dynamic multiple priors and dynamic variational preferences in ...
Growing lake with growing problems: integrated hydrogeological investigation on Lake Beseka, Ethiopia
(2009-02-03)
The complex tectonic and volcanic processes in the Ethiopian rift valley have resulted in the formation of volcano-tectonic structural depressions that became sites for many rift valley lakes. Lake Beseka is one of the ...
Cold atom physics using ultra-thin optical fibres
(2009-01-28)
In this thesis I present experiments concerning the investigation and manipulation of cold neutral atoms using ultra-thin optical fibres with a diameter smaller than the wavelength of the guided light. In such a fibre-field ...
Inverse spectral theory and relative determinants of elliptic operators on surfaces with cusps
(2009-01-29)
This thesis concerns relative determinants for Laplacians on surfaces with asymptotically cusps ends and the inverse spectral problem on surfaces with cusps. We consider $(M,g)$, a surface with cusps, and a metric on the ...
A Study of Low-Dimensional Inhomogeneous Systems
(2009-01-23)
In the last decades there has been enormous progress in the fabrication of nanoscopic quasi-one-dimensional systems, e.g., carbon nanotubes, semiconducting quantum wires, and conducting organic molecules. These materials ...
Higher Green’s functions for modular forms
(2009-03-12)
Higher Green functions are real-valued functions of two variables on the upper half plane which are bi-invariant under the action of a congruence subgroup, have logarithmic singularity along the diagonal, but instead of ...
Hydrophilic Ionic Liquid Mixtures of Weakly and Strongly Coordinating Anions with and without Water
(2018-08)
With the aid of ab initio molecular dynamics simulations, we investigate an ionic liquid (IL) mixture composed of three components 1-butyl-3-methylimidazolium [C4C1Im]+, ...
On the Implications of Unobserved Technology and Preference Shifts for Aggregate Labor Demand and Supply
(2009-08-14)
The macroeconomic approach to the labor market aims at explaining aggregate labor market phenomena that have been present in many industrialized countries such as the United States or the western European countries in the ...
