Studien zur Biosynthese des Hormaomycins
(2012-08-29)
In der vorliegenden Arbeit werden Experimente zur Aufklärung der Biosynthese, Untersuchungen zum evolutionären Ursprung der Adenylierungsdomänen und Studien zur Flexibilität der Biosyntheseenzyme des bakteriellen Peptids ...
Optische Spektroskopie von PTCDA auf Alkalihalogenidoberflächen: vereinzelte Moleküle und Monolagen
(2012-08-03)
In dieser Dissertation wurden die strukturellen und optischen Eigenschaften organischer p-konjugierter Moleküle, die auf einer einkristallinen Oberfläche adsorbiert waren, untersucht. Die Untersuchungen sind damit relevant ...
Modeling Gas-Grain Chemistry in Dark Cloud Conditions
(2012-08-23)
I first wrote a gas phase chemical code, which solves for the gas phase composition of an interstellar cloud as a function of time. We used this code to study the abundance ratios between the H3+ ...
Trapping fermionic potassium atoms in a quasi-electrostatic optical dipole potential
(2012-08-03)
Ultracold quantum gases have become a frequently used tool for the investigation of a variety of physical issues within the last decade, ranging from general questions in quantum physics up to special topics, e.g. quantum ...
Testing X-Ray Scaling Relations with a Sample of Chandra Galaxy Groups and Detailed Analysis of A2244 with Chandra and Suzaku
(2012-08-12)
Groups and clusters of galaxies are valuable tools for cosmology, especially with respect to their mass and other global properties. Individual clusters are also useful to study the complex gravitational and non-gravitational ...
Charakterisierung der Veto-Funktion von hepatischen Sternzellen
(2012-08-01)
Die Leber spielt eine entscheidende Rolle bei der Induktion der T-Zell-Toleranz. Diese wird insbesondere durch die Funktionen von tolerogenen hepatischen Antigen-präsentierenden Zellen und regulatorischen T-Zellen erzielt. ...
Reconstruction of Human Motions Based on Low-Dimensional Control Signals
(2012-08-09)
This thesis addresses the question to what extent it is possible to reconstruct human full-body motions from very sparse control signals.
To this end, we first investigate the use of multi-linear representations of ...

Measurement of polarization observables in the reaction γp →pπ0π0 using linearly polarized photons with the CBELSA/TAPS experiment
(2012-08-10)
The spectrum and the properties of baryon resonances can be studied using photons with energies appropriate to excite baryonic states. Double meson photoproduction allows access to cascading resonance decays via other ......
Development of Selective Nitrile Inhibitors and ‘Activity-Based’ Probes For Human Cathepsins K and S
(2012-06-20)
Cysteine cathepsins show a high degree of similarity and play a significant role in many (patho)physiological processes such as bone remodeling, antigen presentation, osteoporosis, autoimmune disorders, and cancer. Therefore, ...
Bestimmung der Doppelpolarisationsobservablen G in π0-Photoproduktion
(2012-07-18)
Die Hadronenspektroskopie stellt zur Untersuchung des inneren Aufbaus der Nukleonen und damit der Wechselwirkung zwischen den Konstituenten, den Quarks, ein geeignetes Mittel dar. Die bereits gemessenen Anregungszustände ...
