Ultrasonic tomography for the characterization of the weathering state of marble
(2021-05-25)The present thesis investigated the application of ultrasonic tomography to evaluate the weathering condition of different marble varieties. Ultrasound analysis is a non-destructive examination method which is often used ... -
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 ... -
Unmixing of Phosphorus-bearing Melts on Earth and Mars
(2019-04-17)The aim of this study lies in the investigation on unmixing in aluminosilicate melts. Therefore, six glasses of peralkaline and peraluminous compositions were synthesized in the system CaO-Al2O3-SiO2, Na2O-Al2O3-SiO2 and ... -
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, ... -
USE OF GIS MODELLING IN ASSESSMENT OF FORESTRY LAND'S POTENTIAL IN THUA THIEN HUE PROVINCE OF CENTRAL VIETNAM
(2008-07-22)Land suitability assessment is a prerequisite for sustainable forestry production. It involves simultaneous consideration of geo-morphological and ecological factors and environmental and socio-economic aspect ... -
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 ... -
Variations in magma composition in time and space along the Central Andes (13°S-28°S)
(2006-11-01)Meso-Cenozoic magmatic arc systems of the Central Andes (CA) result from the subduction of the Nazca Plate beneath the South America plate since Jurassic time, the arc progressively shifted ... -
Verbundene Mikroporosität in Kristallingesteinen
(2001-06-13)The necessity of depositing radioactive wastes and other toxic substances sealed off from the biosphere, led to the idea of the creation of underground disposal sites in suitable geological ... -
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 ... -
Volatilitätskontrollierte Fraktionierung refraktär-lithophiler Elemente in Meteoriten und der Erde
(2014-08-14)During the condensation of the elements in the early solar system, volatility-controlled fractionations occurred. Such fractionations of refractory lithophile elements in individual chondrite components and between bulk ... -
Volcanic Rocks from Central Italy: An Oxygen Isotopic Microanalytical and Geochemical Study
(2001-02-22)The aim of this work is an investigation on the origin of the Tertiary and Quarternary volcanic rocks in central Italy. The volcanism in this region is characterised by potassic to ultrapotassic ... -
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 ... -
Volcanotectonic Evolution and Characteristic Volcanism of the Neovolcanic Zone of Iceland
(2008-07-10)The thesis focuses on three aspects of the volcanotectonic activity in the Neovolcanic Zone of Iceland: (1) effects of deglaciation, (2) mechanical interaction between central volcanoes, ... -
Waldkonversion und Bodendegradation im tropischen Tiefland von Ostbolivien
(2006-04-21)The objective of the present study was to assess the main types of soil degradation such as nutrient decline (e.g. soil organic matter) and soil compaction caused by different land use ... -
Waldkonversion und Bodendegradation in Bergnebelwaldgebieten Guatemalas (Alta Verapaz)
(2003-11-28)Due to their number of ecological functions and endemic flora and fauna, the tropical montane cloud forests of Guatemala need to be protected. They were classified by the World Bank as ... -
Water level response to harmonic disturbances in confined aquifers: modeling, global sensitivity, and applications
(2024-06-13)In well-aquifer system, oscillatory water levels are often observed in monitoring wells when the aquifer is perturbed by harmonic disturbances, such as oscillatory pumping, ocean tide and seismic waves. In general, the ... -
Water management strategies towards sustainable agricultural development, taking Managed Aquifer Recharge (MAR) and brackish water utilization into Account: Case Study: Auja, LJV, Palestine.
(2019-06-07)Increasing water irrigation demand combined with water scarcity and deterioration of the water quality in the Lower Jordan Valley (hereafter referred to as LJV) - Palestine, has led to a serious challenge in managing ... -
