Pore-Scale Modelling of Induced-Polarization Mechanisms in Geologic Materials
(2019-03-20)
This thesis is concerned with mechanistic pore-scale models, which relate the induced-polarization (IP) response of geologic materials to the underlying physical and chemical processes. Although a sound understanding of ...
Untersuchungen zur Bodenerosion auf der Kanarischen Insel Hierro: Ursachen, Entwicklung und Auswirkungen auf Vegetation und Landnutzung
(1987)
Die Untersuchungen der vorliegenden Arbeit führen von einer Bodenklassifikation über die genaue Erfassung und den statistischen Vergleich repräsentativer Standorte schließlich zu der Herausarbeitung von vier unterschiedlichen ...
In situ observations of reaction and transport phenomena during silicate glass corrosion by fluid-cell Raman spectroscopy: Method development and applications
(2020-07-06)
Borosilicate glass is the preferred material for the immobilization of high-level nuclear waste and an important material for various industries. Silicate glasses, however, are prone to corrosion by aqueous solutions, which ......
Numerical investigations of heat and mass transport in fractured porous rock masses
(2019-01-08)
Fluid flow processes in the subsurface are accompanied by heat and mass transport with several important feedbacks including reactive flow, and precipitation/dissolution processes. Heat and mass transport through fractured ...
Molar dentition of the docodontan Haldanodon (Mammaliaformes) as functional analog to tribosphenic teeth
(2019-06-18)
All extant mammals save the monotremes descend from an ancestor with tribosphenic tooth morphology, characterized by a distally situated crushing basin (talonid basin) on the lower and an interlocking cusp (protocone) on ......
Molarenbezahnung des Docodonten Haldanodon (Mammaliaformes) als funktionelles Analogon zu tribosphenischen Zähnen
Alle heutigen Säugetiere mit Ausnahme der Monotremen stammen von einem Vorfahren mit ......

A Dispositional Perspective of Resilience and Power: An Application of Power Asymmetries in Farming Communities in Caroni, Trinidad and Tobago
(2019-06-04)
Global change processes such as climate change and its impact on food systems, coastal communities and small island states requires us to rethink how sustainable development can be achieved in these coupled environments. ...
Model-based Source Partitioning of Eddy Covariance Flux Measurements
(2019-05-03)
Terrestrial ecosystems constantly exchange momentum, energy, and mass (e.g., water vapor, CO2) with the atmosphere above. This exchange is commonly measured with a micrometeorological technique, the eddy covariance ...
Holocene environmental and climate change in the southern Levant: diatom-based palaeolimnology of Lake Kinneret (Israel)
(2019-05-07)
The Eastern Mediterranean and especially the southern Levant are key regions for palaeoclimatological and palaeoenvironmental research due to their highly complex topography and climatic variabilty. Nevertheless, our ...
Evaluating the Contribution of Remote Sensing Data Products for Regional Simulations of Hydrological Processes in West Africa using a Multi-Model Ensemble
(2019-05-02)
Water is a crucial resource for human health, agricultural production and economic development. This holds especially true in West Africa, where large parts of the population work as self-sustaining farmers. Accurate ......
Hydrogeology and water quality of wetlands in East Africa: case studies of a floodplain and a valley bottom wetland
(2017-10-10)
This thesis is embedded in the interdisciplinary BMBF-funded project “GlobE – Wetlands in East Africa”, which focuses on reconciling future food production in East African wetlands with the concurrent environmental protection ...
