Zur trägerarmen (n.c.a.) 18F-Fluoralkylierung mit Trifluormethansulfonsäure aktivierten Fluoralkoholen
(2012-05-18)
Ergebnisse: Es konnten zwei prosthetische Gruppen für die n.c.a. N/O/S -[18F]-Fluoralkylierung von möglichen Radiotracern etabliert werden. Die eine etwas weniger reaktive Verbindung 1-Brom-2-[18 ......
Ultrastrukturelle Analyse sowie Steuerung der Substratadhäsion kardialer Zellen
(2012-06-04)
Fokaladhäsionen symbolisieren nicht nur einfache starre Verankerungspunkte der Zelle an das extrazelluläre Substrat, sondern sie stellen hochdynamische Multiproteinaggregate innerhalb der Zelle dar, die je nach Anforderung ...
Dual weights in the theory of harmonic Siegel modular forms
(2012-07-13)
We define harmonic Siegel modular forms based on a completely new approach using vector-valued covariant operators. The Fourier expansions of such forms are investigated for two distinct slash actions. Two very different ...
Single impurity atoms immersed in an ultracold gas
(2012-06-20)
In this thesis, experiments with an ultracold gas doped with few and single atoms of another species are presented.
The techniques to adequately prepare and manipulate an ultracold Rb gas and to dope it with a precisely ...

Weak and Measure-Valued Solutions of the Incompressible Euler Equations
(2012-06-21)
This thesis is concerned with the existence problem for weak solutions of the incompressible Euler equations in arbitrary dimension, and with the relationship between weak solutions and other "very weak'' concepts of ...
Analyses of Adhesion Topography and Fluctuations in Bio-Membranes by Advanced Optical Microscopy
(2012-05-21)
The cell membrane not only mechanically separates the interior of the cell from the exterior environment but is also an active organelle involved in a host of functions like maintaining osmotic balance, aiding in ...
DNA barcoding & multi-isotopic fingerprinting: a novel forensic toolbox for the rapid identification of illegal trade in endangered wildlife species
(2012-05-08)
Over-exploitation through illegal wildlife trade is a major threat to a wide range of endangered mammal species around the world, particularly to the Felidae. Illegal trade in wild cats is often in the form of bones, meat, ...
Kontrolle der lateralen Organisation von Membranproteinen
(2012-06-12)
In den letzten Jahrzehnten wurde bei Untersuchungen an Zellmembranen deutlich, dass viele Membranproteine nicht, wie ursprünglich angenommen, homogen verteilt sind, sondern in Mikrodomänen organisiert vorkommen. Die ...
Distributed Management of Grid-based Scientific Workflows
(2012-05-14)
Grids and service-oriented technologies are emerging as dominant approaches for distributed systems. With the evolution of these technologies, scientific workflows have been introduced as a tool for scientists to assemble ...
Measurement of the top quark pair production cross section with the ATLAS detector at LHC in pp collisions at √s =7 TeV in dilepton final states
(2012-06-04)
The production cross section of top quark pairs in proton-proton collisions at center-of-mass energy of 7 TeV recorded with the ATLAS detector at the CERN Large Hadron Collider is measured. The goal of the analysis is to ...
