Investigating astrophysical plasmas with pulsars using LOFAR and other telescopes
(2015-02-19)
Pulsars are rapidly-rotating, highly-magnetised neutron stars that produce radio emission in their magnetospheres, which is detected as pulses on Earth. The focus of this thesis is observing pulsars as the means to study ...
Learning with Graphs using Kernels from Propagated Information
(2015-03-03)
Traditional machine learning approaches are designed to learn from independent vector-valued data points. The assumption that instances are independent, however, is not always true. On the contrary, there are numerous ...
Rolle des Signalgebers MyD88 bei der UV-induzierten Aktivierung des Immunsystems
(2015-03-02)
UVB-Strahlung führt neben der Induktion von DNS- und Zellschäden zu akuten Entzündungsreaktionen. Ferner ist UV-Strahlung in der Lage bei chronischer Exposition immunsuppressive Wirkung auszulösen. Dennoch ist bis heute ...
Virus diversity and cross-species transmission of viruses from the strawcoloured fruit bat Eidolon helvum
(2015-01-06)
Bats are increasingly recognized as hosts of viruses which are significant for human and domestic health. However, the dynamics of these viruses in their natural hosts remain poorly elucidated. In this study, virus diversity ......
Massenspektrometrische Analyse von enzymatisch-chemischen Verdaus zur Detektion vonPhotoaffinitätsmarkierungen des ABC-Transporters P-Glykoprotein
(2015-08-19)
Der ATP-binding cassette (ABC) Transporter P-Glykoprotein (P-gp) stellt den aus medizinischer Sicht wichtigsten humanen ABC-Transporter dar. Aufgrund seiner ubiquitären Expression in Geweben mit Barrierefunktion und ...
The Tagging System of the BGO-OD experiment
(2015-06-17)
In the course of my PhD work, I have been involved in the development and the construction of the Tagging System for the BGO-OD experiment at the ELSA accelerators of the University of Bonn.

Synthesis and structure-activity relationships of α,β-methylene-ADP derivatives: potent and selective ecto-5-nucleotidase inhibitors
(2015-08-19)
Ecto-5'-nucleotidase (ecto-5'-NT, eN, CD73, EC 3.1.3.5) is a member of the group of ecto-nucleotidases which dephosphorylate extracellular nucleotides. eN catalyzes the dephosphorylation of nucleoside monophosphates and ......
A study of the state-nature relations in a developmental state: The case of South Korea’s water resource policy, 1961-2015
(2015-08-19)
The East Asian ‘developmental state thesis’ (hereafter, DST) was suggested to explain the East Asian development states (i.e. Japan, South Korea, Taiwan and Singapore), where the role of the state has been very significant ...
Energy conservation in aceticlastic methanogenic archaea and the human gut archaeon Methanomassiliicoccus luminyensis
(2015-07-29)
Methanogenic Archaea produce methane from products of anaerobic bacterial metabolism. Therefore, they play a central role in global carbon cycling. The fact that methane is a potent green house gas further stresses the ......
Selenium modification of Rh(111) surfaces: Structure and electroactivity for oxygen reduction
(2015-07-29)
Apart from expensive metals, metal chalcogenides are considered as catalyst because they facilitate the ORR and tolerate organics. Existing studies in this area concentrate on nanoparticles, consequently offering little ...
