Characterisation of Brainstem Lateral Line Neurons in Goldfish, Carassius auratus: Frequency Selectivity, Spatial Excitation Patterns and Flow Sensitivity
(2010-02-02)
In the present study lateral line units in the medial octavolateral nucleus (MON) in the brainstem in goldfish, Carassius auratus, were extracellulary recorded. The aim of the work was to investigate and characterize the ...
Granulares Modell zur Simulation der Ermüdung von Metallen
(2010-01-27)
Materialermüdung ist im Alltag der Menschen und durch die entstehenden Kosten für die Wirtschaft ein Problem. Als Alternative zum bisher zur Abschätzung der Lebensdauer verwendeten material- und zeitintensiven Wöhler-Verfahren ...
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 ...
How to predict the future? On niches and potential distributions of amphibians and reptiles in a changing climate
(2009-11-11)
The present Ph.D. thesis investigates relationships between variations in large scale climate, niches of amphibians and reptiles and their corresponding geographic distribution patterns. As suggested by several authors, ...
Soil characteristics and soil erosion by water in a semi-arid catchment (Wadi Drâa, South Morocco) under the pressure of global change
(2009-11-24)
Soil resources are crucial for the well-being of man and the environment. The results of the first Global Assessment of Human-induced Soil Degradation (GLASOD) indicate that 13% of the world’s soils are degraded; thereof ...
Die deutschen Weinbaugebiete: ihre historisch-geographische Entwicklung und wirtschafts- und sozialgeographische Struktur
(1956)
Der Weinbau als Intensivkultur hat seit Jahrzehnten das Interesse der verschiedensten Wissenschaften wachgerufen. Es gibt daher bereits zahlreiche Untersuchungen über den Weinbau in Deutschland und in den einzelnen ...
