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 ...
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 ...

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 ...
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 ...
Lichtinduzierter Ladungstransport in undotierten Lithiumniobat-Kristallen
(2012-06-14)
Die Kombination von optischer Nichtlinearität und der Möglichkeit zur ferroelektrischen Domänenstrukturierung machen Lithiumniobat-Kristalle zu einem der wichtigsten Materialien im Bereich optischer Technologien. Unerwünschte ...
Differential Cross Section Distributions and Polarization Observables in the Reaction p⃗p →pK0Σ+ at p⃗p = 2.95 GeV/c
(2012-12-05)
The reaction p⃗p → pK0S+ was studied with the upgraded COSY-TOF detector. A polarized proton beam with momentum 2.95 CeV/c of the Cooler Synchrotron at Forschungzentrum Jülich was focused on a liquid ...
Bestimmung von Polarisationsobservablen in der π0 und ω Photoproduktion am Proton mit dem CBELSA/TAPS-Experiment
(2012-11-23)
Ziel des Crystal-Barrel/TAPS-Experimentes am Elektronenbeschleuniger ELSA in Bonn ist die Untersuchung der Nukleon-Resonanzstruktur durch Photoproduktion von Mesonen. Zu diesem Zweck ist die Messung von Polarisationsobservablen ...
Single optical microfibre-based modal interferometer
(2012-11-23)
In this thesis, I report on the experimental investigation and the computer simulation of optical microfibre-based modal interferometers. An optical microfibre (OMF) can be produced from a commercial single-mode optical ...
Diamond and Silicon Pixel Detectors in High Radiation Environments
(2012-10-24)
Diamond pixel detector is a promising candidate for tracking of collider experiments because of the good radiation tolerance of diamond. The diamond pixel detector must withstand the radiation damage from 10^{16} particles ...
Probing quark mass effects in low-energy hadron physics
(2012-12-21)
Since quarks are confined inside hadrons, their properties as well as their contributions to hadronic observables can be assessed by indirect methods only. As the strength of the strong interaction increases with the spatial ...
