Mechanismen der hepatischen Immunregulation
(2011-10-21)
Die Leber vermittelt als immunmodulatorisches Organ einerseits eine periphere Immun-Toleranz, muss aber andererseits bei einer Infektion gleichzeitig die Induktion einer Immunantwort zulassen, die in der Lage ist, infizierte ......
The Zinger deformation of differential equations with maximal unipotent monodromy
(2011-10-28)
In this thesis, in the first part we study the Zinger deformation for the holomorphic solution of a differential equation with maximal unipotent monodromy. It is basically a generalization of the example made by Zinger, ...
The “Atelocerata” – A vanishing hypothesis?: Molecular phylogeny of arthropods with focus on primary wingless hexapods
(2012-09-05)
Arthropods encompass more than three quarters of all described living species. Among arthropods, hexapods are the most abundant group and show an enormous diversity. To understand evolutionary processes of and within ...
Modeling Visit Potential of Geographic Locations Based on Mobility Data
(2012-05-07)
Every day people interact with the environment by passing or visiting geographic locations. Information about such entity-location interactions can be used in a number of applications and its value has been recognized by ...
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. ...
