Structure and stability of biological materials – characterisation at the nanoscale

Mummies are witnesses of the past harbouring information about the lives and fates of our ancestors. By examining them, the conditions of living, dietary, lifestyle and cultural habits as well as maladies in ancient times can be revealed. Knowledge of these maladies can be used to ascertain the evolution of diseases and may be helpful in characterising and treating them today. Uncovering information from mummies, however, depends on the preservation of the mummy tissue. Once degradation sets in,...

Varieties of Entrepreneurship

Mit dem ab Mitte der 1980er Jahre diagnostizierten Übergang in eine globale Wissensökonomie wird Unternehmensgründungen v. a. in den westlichen Industrienationen eine große Relevanz für die Durchsetzung von Innovationen und die Aufrechterhaltung der wirtschaftlichen Wettbewerbsfähigkeit zugesprochen. Dieser Befund hat speziell in den "gründungsschwachen" Marktwirtschaften des kontinentaleuropäischen Raums Debatten über die Notwendigkeit einer Steigerung der Gründungsproduktivität hervorgerufen. ...

Operational Retrieval of Surface Soil Moisture using Synthetic Aperture Radar Imagery in a Semi-arid Environment

Mikrorelief Raummuster von Böden, äolischen Substraten und Flugstäuben im Hochgebirgskarst der Nördlichen Kalkalpen (Reiteralpe, Berchtesgadener Alpen)

Summary The current study presents a unique and intensified interdisciplinary geo-ecological study in the Karst of the Northern Calcareous Alps. This is a study focussing on fundamental research. The investigation area in question focusses on the Reiteralpe in the Berchtesgadener Alps, in which a range of research methods, which in their choice and range have not been used to this extent before, are optimal for further adaptation in silmiliar ecological systems and environments. The results of t...

Using in-field and remote sensing data to monitor permafrost dynamics in Northern Quebec

Using Spatial Data for Geo-Environmental Studies

The physically-based spatially-distributed model PROMET (Processes of Radiation, Mass and Energy Transfer) is applied to the Greater Damascus Basin, which is considered as one of the most important basins in Syria, to serve as a case study of using spatial data for Geo-environmental studies. Like most areas of the Middle East, the study area is characterized by large temporal and spatial variations in precipitation and by limited water resources. Due to the increasing water demand caused by the ...

On the Characteristics and Growth of Biominerals

Die unter dem Einfluss von Organismen entstehenden Minerale können entweder lediglich ein Nebenprodukt des Metabolismus sein oder aber eine Funktion aufweisen, wofür ihre Eigenschaften und Morphologie gezielt vom Organismus gesteuert werden. Der erstere Fall der bioinduzierten Mineralisation wurde in dieser Arbeit bei der Fällung des Minerals Schwertmannit (Fe8O8(OH)6SO4) durch den Bakterienstamm Leptospirillum ferrooxidans angetroffen. Die ursprünglich als bio-spezifisch eingeschätzte Morpholog...

Thermische Entwicklung des Ammersees als regionale Auswirkung des Globalen Wandels

Development and Extrapolation of a General Light Use Efficiency Model for the Gross Primary Production

The global carbon cycle is one of the large biogeochemical cycles spanning all living and non-living compartments of the Earth system. Against the background of accelerating global change, the scientific community is highly interested in analyzing and understanding the dynamics of the global carbon cycle and its complex feedback mechanism with the terrestrial biosphere. The international network FLUXNET was established to serve this aim with measurement towers around the globe. The overarching o...

Soil moisture retrieval using high spatial resolution Polarimetric L-Band Multi-beam Radiometer (PLMR) data at the field scale

A model of volcanic explosions at Popocatépetl volcano (Mexico): Integrating fragmentation experiments and ballistic analysis

Summary The dynamics of magma fragmentation is a controlling factor in the behavior of explosive volcanic eruptions. Fragmentation changes the eruption dynamics from a system of bubbly flow to one of gas-particle flow. To date, the influence of the fragmentation process itself on the eruption dynamics has been largely neglected in eruption models. This is understandable, as the explosive expansion of mixtures of pressurized gases and pyroclasts in volcanic eruptions is a complex process that can...

Molecular Networks Through Surface-Mediated Reactions - From Hydrogen Bonds to Covalent Links

This thesis deals with adsorption, self-assembly, and surface reactions of organic molecules on solid substrates, with the aim to fabricate higher hierarchical twodimensional (2D) structures. It is of genuine interest in materials science to develop strategies and methods for reproducible growth of extended molecular assemblies with specific and desired chemical, physical and functional properties. The experimental technique used was Scanning Tunneling Microscopy (STM) - an outstanding method to...

ADER-DG - Analysis, further Development and Applications

After introducing the Discontinuous Galerkin (DG) method a detailed misfit analysis on its numerical approximation is performed. We investigate the accuracy of the scheme, the element type (tetrahedrons and hexahedrons), the spatial sampling of the computational domain and the number of propagated wavelengths. As the error norm we chose a time-frequency representation, which illustrates the time evolution of the spectral content. The results of this analysis are confirmed by a multi-institutiona...

Assessing Building Vulnerability to Tsunami Hazard Using Integrative Remote Sensing and GIS Approaches

Risk and vulnerability assessment for natural hazards is of high interest. Various methods focusing on building vulnerability assessment have been developed ranging from simple approaches to sophisticated ones depending on the objectives of the study, the availability of data and technology. In-situ assessment methods have been widely used to measure building vulnerability to various types of hazards while remote sensing methods, specifically developed for assessing building vulnerability to tsu...

Tsunami Risk and Vulnerability

The research focuses on providing reliable spatial information in support of tsunami risk and vulnerability assessment within the framework of the German-Indonesian Tsunami Early Warning System (GITEWS) project. It contributes to three major components of the project: (1) the provision of spatial information on surface roughness as an important parameter for tsunami inundation modeling and hazard assessment; (2) the modeling of population distribution, which is an essential factor in tsunami vul...

Textural and Rule-based Lithological Classification of Remote Sensing Data, and Geological Mapping in Southwestern Prieska Sub-basin, Transvaal Supergroup, South Africa

Although remote sensing has been widely used in geological investigations, the lithological classification of the area interested, based on medium-spatial and spectral resolution satellite data, is often not successful because of the complicated geological situation and other factors like inadequate methodology applied and wrong geological models. The study area of the present thesis is located in southwest of the Prieska sub-basin, Transvaal Supergroup, South Africa. This area includes mainly N...
