Modelling and validation of agricultural and forest biomass potentials for Germany and Austria
(2012-07-04)The Biosphere Energy Transfer Hydrology Model (BETHY/DLR), a process model that estimates the net primary productivity of agricultural and forested areas was used to assess biomass potentials for Germany and Austria. ... -
Modelling Soil Erosion, Flash Flood Prediction and Evapotranspiration in Northern Vietnam
(2016-03-08)Water-induced soil erosion (WSE) is a main factor of land degradation in many parts of the world and reported as a main threat to agriculture compared to the second largest risk by wind. Some parts of Vietnam have been ... -
Modelling the porosity loss in granular iron based permeable reactive barriers
(2022-11-24)The quality of groundwater resources globally has been under serious threat due to their exposure to a broad spectrum of anthropogenic pollutants. Permeable reactive barriers (PRBs) are an innovative technology being used ... -
Molecular and cellular differentiation during the early shell field development in Lymnaea stagnalis
(2014-02-13)Since the evolutionary emergence of the molluscan shell in the Pre-Cambrian, diverse shell forms have evolved, which are adapted to various ecological environ-ments. The innovation of the shell facilitated the vast ... -
Molecular characterisation of biomineralising genes in the freshwater pond snail Lymnaea stagnalis
(2018-06-22)Much of the evolutionary success of conchiferan molluscs can be traced back to the ability to construct a biocalcified shell that supports the soft molluscan body and offers protection from predation and desiccation. Only ... -
Monitoring forest fragmentation and carbon storage in the Cerrado Biome of Mato Grosso using optical and SAR satellite images
(2021-01-15)Several studies suggested that forest fragmentation, which is an effect of deforestation, and edge effect have an impact on the biomas and carbon stock in tropical forest. For Amazon and Atlantic Forest biomes, most studies ... -
Multi-Method Chronometric Constraints on the Thermal, Structural and Morphotectonic Evolution of the Eastern and Western Sierras Pampeanas with Special Emphasis on K-Ar Dating of Fault Gouges
(2013-08-20)The thesis presented here is focused on the in investigation of the thermochronological, structural and morphological evolution of the Eastern and Western Sierras Pampeanas in Argentina between 26°S and 34°S latitude. ... -
Natural Resource Use Conflicts in Indonesia: A Challenge for Sustainable Development and Education for Sustainable Development
(2012-06-05)Many of Indonesia's natural resources are degraded due to over-utilization. Examples are over-exploitation of fish stocks or non-timber forest resources. In many cases commons dilemmas' regularly occurring in open access ... -
Naturraum und Wirtschaftspotenzial in Westchina − Chancen für ausländische Unternehmen?
(2007-06-13)The Chinese economy is nowadays one of the fastest growing in the world, with an average increase of more than 8 % per year. Therefore China is worldwide one of the most attractive location ... -
Naturwerksteine Thailands: Lagerstättenerkundung und Bewertung
(2007-05-02)The last three decades were characterised by a continuous growth with respect to the demand of dimension stones. At the present time it is already obvious that the large quantities that are ... -
Neoproterozoische bis paläozoische Krustendynamik am Westrand des Río de la Plata Kratons
(2010-03-16)Whole rock geochemical analyses using major and trace elements in combination with the Sm-Nd and Pb-Pb isotope systems together with SHRIMP age dating on metasedimentary rocks from the ... -
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 ... -
Numerical simulation of permeability heterogeneity in single- and two-phase flow systems to assess the performance of enhanced geothermal system
(2022-11-09)The development of Enhanced Geothermal System (EGS) technology leads to the possibility of an extensive application of geothermal energy, which is attractive because of its ability to reduce CO2 emissions and dependence ... -
Numerische Untersuchungen zur Wechselwirkung von Mantelplumes mit Mittelozeanischen Rücken
(2000-08-21)The interaction of mantle plumes with mid-ocean ridges is investigated in 3-D numerical convection models. A new numerical method for solving convection problems with variable viscosity in ... -
Observations, analysis and interpretation with non-LTE of chromospheric structures on the Sun
(2008-05-27)The Sun possesses a complex layer called chromosphere, which extends above the overwhelmingly bright photosphere. With decreasing density, the solar magnetic fields start here to dominate the dynamics, giving rise to new ... -
On the possibility of using organic molecules in the characterization of subsurface processes
(2013-05-15)Nowadays, tracer tests represent an important part in the repertoire of hydro(geo)logical characterization techniques. For determining hydromechanical parameters of and flow properties within a reservoir or an aquifer, ... -
On the significance and predictability of geological parameters in the exploration for geothermal energy
(2018-05-02)Sufficient reservoir permeability is essential to exploit heat resources for geothermal energy. Reliable prediction of permeability and in consequence flow rate in a deep geothermal reservoir is difficult to predict because ... -
