Loess-palaeosol sections along the Rhône Rift Valley (SE France) as Late Quaternary palaeoenvironmental archives
(2024-03-05)Loess-palaeosol sections (LPSs) represent ideal archives for gaining knowledge of past climatic conditions and changes, as their intermediate loess deposits and buried palaeosols reflect climate conditions of their ... -
Effects of solid additives and inorganic ligands on the efficiency of metallic iron- based water treatment system
(2024-02-23)Metallic iron (Fe0) or zero-valent iron (ZVI) has been extensively used for water remediation during the past three decades. It has been proven to be effective in treating waters polluted with chlorinated aliphatics, dyes, ... -
Classification of main irrigated crop types towards sustainable development using Landsat and Sentinel data by GIS and remote sensing techniques in a semi-arid area in Tashkent Province, Uzbekistan
(2024-02-02)As the world population increases and cropland expansion occurs, there will be a high need in the food supply soon which will require higher agricultural yields. Crop yield estimation, management, and production assessments ... -
Understanding heat transport processes in shallow subground resulting from external and internal impacts
(2024-01-18)Heat conduction in the subsurface environment is the result of internal and external impacts and is governed by different forces in the short and long term. Externally, this phenomenon is related to daily temperature ... -
Lower Cretaceous Geothermal Reservoirs in the North German Basin
(2023-10-02)This thesis contributes to the strategic effort to make Germany’s energy supply more sustainable. The primary focus of this study was to enhance and update the geological knowledge of the Mesozoic deep geothermal sandstone ... -
Sustainability Transitions in German Livestock Farming: The Role of Innovations, Incumbents, and Imagined Futures
(2023-08-10)Environmental degradation, climate change, and issues of social justice highlight the need to develop and transition to more sustainable modes of production, consumption, and living. Livestock farming in Germany is a sector ... -
Carbonate factories in the early Archean and their geobiological impacts
(2023-08-08)Paleoarchean carbonates in the Pilbara Craton (Western Australia) are important archives for early life and environment on early Earth. Amongst others, carbonates occur in interstitial spaces of ca. 3.5–3.4 Ga pillow basalts ... -
The Distribution of Water in the Lunar Magmatic Ocean
(2023-07-17)Water plays an important role for many geological and organic processes. Nevertheless, it is still unclear why our Earth has such large quantities of it. Either it has been part of the building blocks of our planet or was ... -
Diagenetic controls on sandstones of the Stuttgart Formation – consequences for the porosity evolution of hydrothermal reservoirs in the North German Basin
(2023-07-05)The present dissertation is part of the R&D project GeoPoNDD, which deals with the potential use of the six main Mesozoic geothermal reservoir complexes in Northern Germany. The hydrothermal reservoirs of the Stuttgart ... -
Early Earth mantle heterogeneities
(2023-07-04)Determining isotopic signatures established in the Hadean mantle offers far-reaching insights into the origin of Earth’s accreted building blocks, core formation, mantle differentiation as well as the formation of Earth’s ... -
Optimierung der Eigenschaften von neuartigem Elektrobandstahl
(2023-05-23)In the present work, the influence of silicon (Si) and particularly aluminium (Al) on the properties of electrical steel is studied. The aim is to decrease magnetization losses and therefore increase the efficiency of ... -
Impact of climate change on recharge and vadose-phreatic storage dynamics of a Mediterranean karst aquifer: Quantitative approach for the management of a complex groundwater resource
(2023-04-11)The Mediterranean basin will be severely affected by global warming and decreased average rainfall and is often portrayed as the most prominent climate change hotspot. At the same time, the Mediterranean basin is endowed ... -
Impacts of rainforest transformation into oil-palm plantations on silicon pools in soils
(2023-03-30)Silicon (Si) is the second most abundant element in the Earth’s crust. In rocks, Si primarily occurs as primary silicates. In soils, Si is present mostly as secondary silicates or amorphous silica of biogenic or pedogenic ... -
Kommunalismus und Raumproduktion am Beispiel der indischen Metropole Hyderabad
(2023-01-11)Hyderabad is a fast growing emerging Indian Megacity. Along with globalisation rapid and drastic changes have taken place resulting in spatial fragmentations and new conflicts. The Muslim-dominated old city of Hyderabad ... -
Political Change and Urban Growth in a Medium-sized Outer Island Capital in Indonesia: The Case of Palu, Central Sulawesi
