Use of selected anthropogenic pesticides, nutrients, and biomarkers to spatially and temporally characterize eutrophication dynamics at a shallow lake (Lake Seeburg)
(2022-11-09)Eutrophication of water bodies caused by high nutrient inputs, especially of phosphorus, is a global concern for a wide variety of ecosystems. To assess this problem, different monitoring approaches have been applied to a ... -
Pore- and core-scale studies for development of the Kinetic Interface Sensitive tracer – A novel reactive tracer technique to measure the fluid-fluid interfacial area for dynamic two-phase flow in porous media
(2022-11-04)Fluid-Fluid Interfacial Area (FIFA) is an important parameter relevant in numerous geological applications where two phases of fluids exist and interphase reactive mass transfer can happen. For example, in geological storage ... -
Characterization of Hydraulic Properties in Fractured Aquifers Using Slug Test-based Hydraulic Tomography and Thermal Tracer Tomography
(2022-10-25)Fractured aquifers are widely distributed on the earth’s surface and are frequently encountered in many underground projects, such as groundwater resource evaluation, contaminants remediation, and geothermal energy ... -
Towards a high-quality interannual to millennial ice-core based temperature reconstruction for East-Antarctica
(2022-09-16)Instrumental observations of climate cover only the past ~200 years. Our knowledge about historical natural climate variability beyond this time is exclusively based on climate proxies, stored within natural archives. ... -
Biotechnology and the socio-biological production of vulnerability. Genetically engineered cotton in Telangana, India
(2022-08-12)The use of genetically engineered (GE) crops in agriculture has been the subject of fierce controversy worldwide for decades and remains so until today. The potentials and risks of the technology are still contested and ... -
Ejecta erosion, hydrological, and chemical lake evolution in the Ries impact basin (Miocene, Germany)
(2022-04-08)To inspect past environmental changes and potential habitability, the growing interests for the ancient Martian crater lakes call for better understandings of palaeolimnological evolution of impact crater lakes. Particularly, ... -
Triple oxygen isotope ratios of bioapatite
(2022-04-07)Bioapatite is the major crystalline component of bone and tooth materials. Recent studies demonstrated that bioapatite carries information of animals’ physiology and living environmental conditions and retains its original ... -
Violence and volume: an experimental study of CO2 driven eruptions of Colli Albani
(2022-04-07)This thesis presents the first rheological investigations of melts from the Colli Albani Volcanic District (CAVD) near Rome (Italy). Despite their silica-poor (< 45 wt%) and ultrapotassic composition – indicating a low ... -
A geobiological approach to carbonate factories and ecosystem changes across the Permian–Triassic boundary
(2022-04-05)Contemporary climate change is accelerating. Meanwhile, “Has the Earth’s sixth mass extinction already arrived?” is inquired. The Permian–Triassic crisis, as a possible analog in the Earth history, has aroused great ... -
Above- and belowground biomass and nutrient stocks in monoculture and agroforestry cacao production systems in the Alto Beni, Bolivia
(2022-03-08)There is hardly any place left on earth that can be considered untouched nature. Humans penetrate into all areas of this earth, and may it be through greenhouse gas emissions or other types of air and environmental pollution. ... -
Deep Subduction in Earth history: Seeking for traces in the sedimentary record
(2022-02-24)The global-scale horizontal movement of tectonic plates driven by the sinking of cold and dense lithosphere, known as plate tectonics, is a major process linking the Earth’s surface with mantle. Thus, plate tectonics ... -
Impacts of agricultural land acquisition for urbanization on smallholder agriculture and gender issues in affected communes: A case study in Huong Thuy town, Thua Thien Hue province, Vietnam
(2022-01-04)Abstract Agricultural Land Acquisition for Urbanization (ALAFU) is an inevitable process that has been happening around the world, especially in developing countries. It is the process by which the government acquires ... -
Triple oxygen isotope study on the Earth-Moon system
(2021-12-23)Triple oxygen isotope systematics (Δ'17O) are an established tool to trace and classify extraterrestrial material. This tool is used in the field of cosmochemistry to study the genetic link between different Solar System ... -
Volcanic tuffs as natural building stones
(2021-11-19)The present thesis deals with the deterioration and durability of volcanic tuff rocks used as building stones in historical architecture and presents a combined approach on identifying the main parameters responsible for ... -
Designing and Piloting a household filter for the peri-urban population of Douala (Cameroon)
(2021-11-18)In rural and peri-urban regions of the developing world, many tube wells used as drinking water sources are microbially and chemically polluted. Consequently, hundreds of millions of people lack access to “safe” drinking ... -
Experimentelle Untersuchungen zu Mechanismen von druck- und temperaturinduzierten Phasenübergängen
(2021-10-18)Under the influence of pressure and/or temperature changes, crystalline materials undergo a phase transition. The directions of the crystalline unit cell before and after the phase transition can show orientation relations. ... -
Carbon Dioxide un ultrapotassic silicate melts: Experimental insights on solubility and decompression induced vesicle nucleation
(2021-10-01)Until today, the explosivity of volcanic eruptions cannot be forecasted by even the most modern monitoring techniques. The processes causing these events, endangering the lives of millions of people, happen deep inside the ... -
