Definition, Teilimplementation und Verifikation eines vollautomatischen Vermittlungssystems für den Personentransport
Author(s) :
Zegartowski, Lutz
Description :
The PeopleLogistic CORONA, developed in the Institute of Transport and Computer Science, is a complex simulation system for traffic, an analysing tool and also a real-time mediation system for a large population. CORONA mediates routes local, regional and countrywide finding the minimum of vehicle m...

Ionentransporte in C6-Glioma-Zellen bei oxidativem Streß
Author(s) :
Düßmann, Heiko
Description :
In this work the dose dependent disorders of ion transport processes and mitochondrial membrane potential caused by hydrogen peroxide were investigated with fluorescencespectroscopic methods in C6-Glioma-Cells. These cells served as a model system for one glial subtype, the astrocytes. The transitio...

Untersuchung der elektrischen Eigenschaften breitlueckiger Halbleiterschichtstrukturen für optoelektronische Anwendungen
Author(s) :
Fehrer, Michael
Description :
For electrical characterization, experimental setups for current-voltage-, capacitance-voltage- and theHall-effect-technique were installed and used to get an insight into the electrical behaviourand degradation of the grown devices. Parallel to the optimization of the growth of deviceswithin other ...

Anwendung der Roentgenbeugung zur Analyse der strukturellen Eigenschaften von homo- und heteroepitaktischen Halbleiterschichten auf ZnSe-Basis
Author(s) :
Grossmann, Volker
Description :
An asymmetric relaxation was observed for the azimuth directions [110] and [1-10]. The dislocation density before and after heating was estimated from the diffuse scattering. Values of 3.3 *10^3 /cm and 13 *10^3 /cm were derived for the [110]-azimuth direction. The residual strain of single ZnSe lay...

Quantifizierung von Strukturen, Kinetik und Dynamik nekrobiologischer Prozesse mit Hilfe bildverarbeitender konfokaler Fluoreszenzmikroskopie
Author(s) :
Härtel, Steffen
Description :
Translocation of phosphatidylserine (PS) from the inner to the outer plasma membrane leaflet is presently discussed as a hallmark of apoptosis. The signalling which initialises the process and the translocation mechanism itself are still under investigation. Diffusion or enzymatic transport is suspe...

Inversion globaler Ozonvertikalverteilungen aus Messungen des Satelliteninstruments GOME
Author(s) :
Hoogen, Ricarda
Description :
Die stratosphaerische Ozonschicht schuetzt die Biosphaere vor der schaedlichen kurzwelligen UV-Strahlung. Spaetestens seit der Entdeckung des antarktischen Ozonlochs gilt es als erwiesen, dass diese wichtige Schutzschicht durch den Menschen akut gefaehrdet ist. UmVeraenderungen der Ozonverteilung re...

Strukturelle Charakterisierung von Gruppe-III-Nitriden mit Hilfe der hochaufloesenden Roentgenbeugung
Author(s) :
Kirchner, Verena
Description :
The investigation of typical defects in GaN layers is based on both X-ray results and transmission electron microscopy investigations from H. Selke. The defect structure in GaN layers grown on GaN nucleation layers is dominated by edge type threading dislocations and inversion domains. Furthermore, ...

Analyse hydrographischer Schnitte mit Satellitenaltimetrie
Author(s) :
Losch, Martin
Description :
Dedicated satellite missions that will lead to high precision, high resolution geoid models are planned and/or in preparation. In this study, a particular method is presented that allows the use of sea surface height data, that is consistent with its error covariance. A first test of the model in a ...

Langfristige Variabilität der thermohalinen Zirkulation in einem gekoppelten Ozean-, Meereis-, Atmosphaerenmodell
Author(s) :
Meissner, Katrin Juliane
Description :
The heat and moisture transports by transient eddies in the EMBM are parameterized by diffusion. The coupled model reproduces many aspects of today´s oceanic circulation. The most interesting features of the coupled model are the sensitivity of the thermohaline circulation to changes in the configur...

Untersuchung von Ceramid- und Adenosinanalogen bei der Apoptose von EL4-Zellen
Author(s) :
Popp, Katja
Description :
The lipids and the fatty acid composition are important regulators of cellular function and the membrane fluidity. The fluorescence dye laurdan was chosen to determine membrane fluidity in terms of generalised polarisation (GP) values in isolated membranes and whole cells. At the early apoptotic sta...
