O-GlcNAc – a posttranslational modification implicated in Alzheimer disease?
(2015-04-22)O-linked N-acetylglucosamine (O-GlcNAc) is a highly dynamic posttranslational modification which has been found on a myriad of nucleocytoplasmic proteins. O-GlcNAc addition and removal are catalyzed by two conserved enzymes, ... -
Oberflächencharakterisierung von III-V MOCVD-Filmen aus heterozyklischen Single Source Precursoren
(2009-09-03)Oberflächencharakterisierung von III-V MOCVD-Filmen aus heterozyklischen Single Source Precursoren In vielen mikro- und optoelektronischen Bauteilen finden Antimon-haltige Verbindungshalbleiter Verwendung. Insbesondere ist ... -
Oberflächenmodifizierung von Lactose mit überkritischem CO2
(2003)In der pharmazeutischen Industrie gewinnen die Mikronisierung und die Oberflächenbehandlung mit überkritischen Fluiden immer mehr an Bedeutung.
Ein Stoff wird zum überkritischen Fluid, wenn Druck und Temperatur über ... -
Objective and quantitative methods in the study of dinosaur tracks
(2019-02-05)This dissertation develops and employs objective and quantitative methods for the analysis of dinosaur tracks. Tracks are—besides the familiar bones and teeth—a crucial data source for inferences on dinosaur biology and ... -
Observation of top quark pair production and estimation of W+jets background with ATLAS at the LHC
(2010-12-22)An analysis has been presented based on an integrated luminosity of 2.9 pb-1 of 7 TeV center-of-mass energy proton-proton collision data in ATLAS at the Large Hadron Collider. The data have been collected since ... -
Observation of W → τντ Decays with the ATLAS Experiment
(2011-05-04)Physics studies of processes with t leptons in the final state, while challenging at hadron colliders, are of great importance at the LHC. The τ leptons provide important signatures in searches for the Higgs boson as well ... -
Observations of the Sunyaev-Zel'dovich Effect towards Clusters of Galaxies with the APEX Telescope
(2009-09-14)Results of 150 GHz continuum observations of several X-ray bright clusters of galaxies in the Sunyaev-Zel'dovich (SZ) effect, carried out using the APEX-SZ bolometer array on the APEX telescope, are presented. Follow-up ... -
Obstruction theory for operadic algebras
(2012-05-21)We study obstruction theory for formality of chain operadic algebras. We construct a canonical class γA for an algebra A over a cofibrant chain operad P∞. This class takes values in the Gamma cohomology ... -

Ocular Onchocerciasis: The Role of Toll-Like Receptor-2 and Interferon-γ
(2010-03-17)River Blindness is still highly prevalent in subsaharan Africa with millions of people suffering from the infection with Onchocerca volvulus. This filarial worm harbors the endosymbiont Wolbachia which was ... -
Off-Label-Use von Arzneimitteln in der Palliativmedizin
(2013-05-07)Es steht außer Frage, dass die gesundheitliche Versorgung unserer Gesellschaft durch den medizinischen Fortschritt in den letzten Jahrzehnten enorm gesteigert wurde. Dabei ist der Schwerpunkt dieser Entwicklung auf Heilung ... -
Old Globular Clusters in Dwarf Irregular Galaxies
(2008)One of the most pressing questions in astrophysics to date is resolving the history of galaxy assembly and their subsequent evolution. In the currently popular hierarchical merging” scenario, massive galaxies are believed ...

Oligozäne Beckendynamik und Sequenzstratigraphie am Südrand des Nordwesteuropäischen Tertiärbeckens
(2004)Durch die Analyse von Bohrdaten aus 230 Explorations- und Forschungsbohrungen wird für die oligozäne Sedimentfüllung am Südrand des Nordwesteuropäischen Tertiärbeckens zwischen Belgien im Westen und Sachsen-Anhalt im Osten ... -
On a kinetic equation arising in weak turbulence theory for the nonlinear Schrödinger equation
(2016-12-22)We present a study of weak solutions to a kinetic equation of coagulation-fragmentation type. This quadratic equation (QWTE) is the leading order approximation for long times to the isotropic space-homogeneous weak turbulence ... -
On affine Deligne-Lusztig varieties for GLn
(2005)In the first part of this thesis we study the global structure of moduli spaces of quasi-isogenies of p-divisible groups introduced by Rapoport and Zink. We determine their dimensions and their sets of connected components ... -
On Analysis of some Nonlinear Systems of Partial Differential Equations of Continuum Mechanics
(2003)In this thesis we consider systems of partial differential equations of continuum mechanics and analyze regularity properties of their weak solutions.
The first chapter contains a detailed introduction and reviews ... -
On Approximability of Bounded Degree Instances of Selected Optimization Problems
(2013-08-07)In order to cope with the approximation hardness of an underlying optimization problem, it is advantageous to consider specific families of instances with properties that can be exploited to obtain efficient approximation ... -
On Approximability, Convergence, and Limits of CSP Problems
(2016-09-16)This thesis studies dense constraint satisfaction problems (CSPs), and other related optimization and decision problems that can be phrased as questions regarding parameters or properties of combinatorial objects such as ... -
On arithmetic families of filtered φ-modules and crystalline representations
(2011-05-10)We consider stacks of filtered phi-modules over rigid analytic and adic spaces. We show that these modules parametrize p-adic Galois representations of the absolute Galois group of a p-adic field with varying coefficients ... -
On arithmetic properties of Fuchsian groups and Riemann surfaces
(2015-02-11)In this thesis, Riemann surfaces and their fundamental groups are studied from an arithmetic point of view. First the image of the absolute Galois group of a number field under Grothendieck's representation with values in ...
