Validation of the COSMO: Land-Surface Parameterization TERRA-ML with discharge measurements
(2010-02-12)
The objective of this study is to eliminate known deficits in the operational land-surface parameterization (LSP) TERRA-ML of the numerical weather prediction (NWP) model COSMO (Consortium for Small-Scale Modeling). A large ...
Optical cleaning of lithium niobate crystals
(2010-03-04)
An all-optical method for the removal of photoexcitable electrons from photorefractive centers to get rid of optical damage in lithium niobate crystals is presented, the so-called "optical cleaning". The method combines ...
Homotopy theory of s-bimodules, naive ring spectra and stable model categories
(2010-02-01)
We study the homotopy theory of S-bimodules which essentially sequential spectra which admit a left and right action of the sphere specturm in a compatible way. The resulting category has non-symmetric monoidal product. ...
Plasmon-Fano Resonance in Electron Conduction Band Coupled to Single Laser Mode
(2010-01-21)
Plasom related physics has been the subject of extensive reserach interests. In this thesis, electron conduction band coupled to single laser mode is studied. The system is nonequilibrium. Keldysh Green's function formalism ...
Charakterisierung und katalytische Eigenschaften cerhaltiger Oxid- und Legierungsoberflächen
(2010-04-07)
Ceroxide werden in der Katalyse häufig als reaktive Komponenten in Edelmetall-Oxid Katalysatoren eingesetzt. Die katalytische Aktivität ist im leichten Wechsel der Oxidationsstufe des Cers sowie des leichten Sauerstoffaustausches ...
A multi-agent system for simulating land-use and land-cover change in the Atankwidi catchment of Upper East Ghana
(2010-01-27)
Land-use and land-cover change (LUCC), which is a general term for the human modification of the Earth’s terrestrial surface, increasingly gains attention in the scientific community, due to its vast global extent and the ...
Das endotheliale Targeting von E-Selektin-gerichteten Immunoliposomen als Ansatzpunkt für neuartige antiinflammatorische Therapieprinzipien
(2010-01-06)
Der chronische Verlauf der Entzündungserkrankungen erfordert einen langfristigen Einsatz, wodurch die Wahrscheinlichkeit des Auftretens schwerwiegender, systemischer Nebenwirkungen bei der Anwendung der meisten Pharmaka ...
Sugars in early and late polyketide biosynthesis: Functional studies of rifL, rifK and rifM in rifamycin biosynthesis
(2010-01-04)
The first section of this work comprises investigations concerning the initial steps in rifamycin biosynthesis. The amino sugar kanosamine was described to represent the most likely source of the nitrogen atom in the ......
Mechanisms of T cell mediated kidney disease
(2010-01-06)
Immune mediated glomerulonephritis (GN) is a major cause renal inflammation leading to terminal kidney failure. B cells and autoantibodies are well known to contribute to the progression of glomerular disease. The role of ...
Lysine-specific histone demethylase 1 (LSD1): A novel molecular target for tumor therapy
(2010-01-27)
Aberrant epigenetic changes in DNA methylation and histone acetylation are hallmarks of most cancers, while histone methylation had been considered to be irreversible and less versatile. Recently, several histone demethylases ...
