Urbanisation, Land Use and Soil Resource: Spatio-Temporal Analyses of Trends and Environmental Effects in Two Metropolitan Regions of Ghana (West Africa)
(2020-12-23)With more than half of the world’s population already urbanised, global sustainability is partly hinged on how the urbanisation process is impacting the natural environment. Therefore, it is important to characterise, ... -
Space-time modelling of seasonal soil moisture for improved crop production – the case of the Guinea savannah region, Ghana
(2020-12-17)The upsurge in advocacy for food security in SSA implies the urgent need for improved sustainable adaptation measures that can boost food-crop production. This is of utmost concern, because, over the past decades, food ... -
Paläoökologische Interaktionen von Organismen aus Baltischem und Bitterfelder Bernstein
(2020-11-06)Because of the quick fixation and detailed conservation of millions-of-years-old arthropods, other small animals and plant parts, amber is very suitable for the conservation of ancient behaviours and interactions. In this ... -
Th-U series radionuclides in the characterization of geothermal reservoirs (Bruchsal, SW Germany)
(2020-10-08)A sophisticated analysis of naturally occurring nuclides has the potential to support geothermal energ\ e[ploitation during various stages of a project·s life c\cle. One possible methodological approach is based on the ... -
Charakterisierung minimaler und maximaler Hemmkonzentrationen verschiedener Spurenelemente in Biogasprozessen und Entwicklung eines vereinfachten Bestimmungsverfahrens
(2020-08-24)For optimal biogas formation processes in biogas plants numerous operating parameters must be within certain limits. A sufficient supply of essential macro- and micronutrients must be guaranteed for the conversion and ... -
Automated data processing and numerical methods for travel-time based hydraulic tomography
(2020-08-13)Travel time based hydraulic tomography is a useful and promising technique for reconstructing the spatial distribution of aquifer hydraulic properties (e.g., hydraulic diffusivity). Simultaneous Iterative Reconstruction ... -
Composition and compositional zoning of olivine as a tracer for pre-eruptive magmatic processes: Application to Piton de la Fournaise, Laacher See, and Shiveluch volcano
(2020-08-12)This dissertation deals with the reconstruction of pre-eruptive magmatic processes with respect to their timescales. Deep recharges of mafic magma into shallower reservoirs and subsequent magma mixing are assumed to play ... -
Generating early continental crust
(2020-07-09)Archean cratons are the products of geodynamic processes governing the evolution of the early Earth. They comprise felsic granitoids enclosed by folded volcano-sedimentary successions. However, these rocks may not be ... -
Marine and terrestrial influence on submarine groundwater discharge in coastal waters connected to a peatland
(2020-06-03)In low-lying coastal fens, groundwater flow direction, water level and input of salts with seawater determine vegetation communities and greenhouse gas emissions, while the export of nutrients and carbon with submarine ... -
Numerical modelling of single- and multi-phase flow and transport processes in porous media for assessing hydraulic fracturing impacts on groundwater resources
(2020-05-28)The environmental footprint of hydraulic fracturing has gained substantial attention in the water – energy nexus as the technology is relatively new and its long-term impacts are not thoroughly understood. Of primary ... -
Constraints on pre-eruptive magmatic history using multi-faceted diffusion modeling: an analytical, experimental and numerical study
(2020-05-28)Time-scales extracted from chemically zoned minerals provide insights into crystal residence time, magma storage and compositional evolution of magmas and allow better constraints on pre-eruptive history of large and ... -
Food and the middle class
(2020-05-25)The global food consumption today is environmentally and socially not sustainable. While greenhousegas emissions increase due to changing diets, the dubble burden of malnutrition persists especially in emerging economies ... -
Kritische Analyse der Rekonstruktionen der letztglazialen Vergletscherung im Nepal-Himalaja (Himalaja Südabdachung)
(2020-05-20)Until today there are significant differences in the views on the course and extent of the glacial glaciation in High Asia. The reasons for this are the different methods respectively working techniques used, the location ... -
Preferential flow dynamics in the vadose zone of fractured and fractured-porous media: Development of a parallelized multi-scale Smoothed Particle Hydrodynamics model
(2020-03-23)The main objective of this thesis is the development of a smoothed particle hydrodynamics (SPH) model to study preferential flow dynamics in partially saturated porous-fractured media at core- and micro scale. The research ... -
Pigments, Colours and Patterns - The contribution of eumelanin and pheomelanin to molluscan shell ornamentation with a special focus on the terrestrial snail Cepaea nemoralis
(2020-02-25)In recent years interest into molluscan pigments increased. But a lot of techniques have to be adapted to be usable with often difficult molluscan tissues and shell material. A comprehensive approach needs to encompass ... -
Produktion öffentlicher Räume in indischen Megastädten
(2019-12-06)Since India’s economic liberalization in the 1990s the cities have undergone tremendous change. It goes along with conflicts about public spaces. This dissertation describes and analyzes the dynamics of mega-urban public ... -
Layerings in the nucleus of comet 67P/Churyumov-Gerasimenko
(2019-11-19)The Rosetta mission to delivered images of comet 67P’s nucleus at unprecedented resolution which indicate the presence of a global layering system. By merging techniques of structural geology, statistical image processing, ... -
Advanced synchrotron texture analysis of phyllosilicate-rich rocks from different tectonic settings – Understanding texture-forming processes and anisotropic physical properties
(2019-11-18)Texture analysis, i.e. the analysis of the crystallographic preferred orientations of minerals in rocks, contributes to the understanding of the deformation history and physical properties of rocks. Methods generally applied ... -
