Precision calculations for the low-energy dynamics of pions and nucleons
(2012-07-18)
QCD is strongly coupled at long distances and therefore non-perturbative methods are required to understand its low-energy properties, e.g. to answer such basic questions as of the origin of the nucleon mass. In this thesis ...
A Statically Typed Logic Context Query Language With Parametric Polymorphism and Subtyping
(2012-07-18)
The objective of this thesis is programming language support for context-sensitive program adaptations. Driven by the requirements for context-aware adaptation languages, a statically typed Object-oriented logic Context ...
Untersuchungen zur Funktion der Fettsäure-2-Hydroxylase (FA2H) in der Haut- und Haarfollikel-Homöostase der Maus
(2012-07-18)
Die Fettsäure-2-Hydroxylase (FA2H) ist das einzige bisher bekannte Enzym, das die α-Hydroxylierung von unverzweigten Fettsäuren katalysiert. Letztere sind Bestandteile von α-hydroxylierten Sphingolipiden, die in der Haut ......
A Detailed Study of Galaxy Clusters with Weak Gravitational Lensing and X-rays
(2012-07-17)
Galaxy clusters represent the top of hierarchical structure formation with the largest dark matter halos. Their abundance with respect to mass and redshift can be used to constrain cosmological parameters. The most extensive ...
Pastoralism under Pressure: Vulnerability of Pastoral Nomads to Multiple Socio-political and Climate Stresses – The Shahsevan of Northwest Iran
(2012-07-18)
Pastoral nomadism is a livelihood source for over 200,000 families in Iran. They rear over 24 million head of animals such as sheep and goats throughout cycles of seasonal migration and thereby utilize over 40% of the ...
Semantics-aware planning methodology for automatic web service composition
(2012-07-23)
Service-Oriented Computing (SOC) has been a major research topic in the past years. It is based on the idea of composing distributed applications even in heterogeneous environments by discovering and invoking network-available ......
Materialwissenschaftliche und strukturelle Untersuchungen an photomechanischen Infrarotrezeptoren bei Insekten zur Optimierung neuartiger technischer Infrarotsensoren
(2012-07-18)
In dieser Arbeit wurden hauptsächlich die mechanischen Eigenschaften hoch spezialisierter Insektenkutikula in photomechanischen Infrarotrezeptoren (IR-Rezeptoren) pyrophiler Insekten bei nahezu natürlichem Wassergehalt ...
Analysis of Trajectories by Preserving Structural Information
(2012-07-18)
The analysis of trajectories from traffic data is an established and yet fast growing area of research in the related fields of Geo-analytics and Geographic Information Systems (GIS). It has a broad range of applications ...
Cichlids of the lower Congo River - a new model system in speciation research?
(2012-05-07)
Fishes account for the highest diversity of all vertebrate groups on our planet. Among them one group clearly outnumbers all the others - cichlids (Perciformes, Cichlidae). The present study focuses on cichlids of the lower ...
Beteiligung ATP-abhängiger Transportprozesse an der Resistenz gegenüber Platinkomplexen
(2012-08-10)
Eine reduzierte zelluläre Kumulation von Cisplatin ist ein häufig beobachteter Mechanismus der Platinresistenz. Es wird vermutet, dass neben der passiven Diffusion auch verschiedene energieabhängige Proteine, welche die ...
