Management Options for Optimizing Nutrient Cycling and Reducing Greenhouse Gas Emissions from Smallholder Rice Farms in Vietnam
(2019-11-15)Summary Rice is the most important food crop in Asia. However, rice production in Asia is facing tremendous challenges in the 21st century. Fast-growing populations are demanding larger rice supplies under the increasingly ... -
Marble decay caused by thermal expansion: microstructure-based mathematical and physical modeling
(2014-01-09)Marbles have been considered to be among the most important building materials since ancient times. Regarded as special stones, they are captivating because of their pureness, formability, and translucence. However, ... -
Marine and terrestrial influence on submarine groundwater discharge in coastal waters connected to a peatland
(2020-06-03)In low-lying coastal fens, groundwater flow direction, water level and input of salts with seawater determine vegetation communities and greenhouse gas emissions, while the export of nutrients and carbon with submarine ... -
Measurement of Absolute Poverty and Indicators of Poverty among Rural Households in Central Sulawesi, Indonesia
(2006-03-13)Poverty is a widespread and pervasive problem in many parts of the world. Many development programs and projects focus on poverty reduction. A precise targeting of the poor is decisive for their success. Therefore, it ... -
Measuring and tracking suspended sediment on tidal flats and inundated marshland: Relevance for vertical accretion rates and coastal protection measures on the North Frisian Halligen
(2021-04-13)Inhabited coastal areas around the world have to deal with sea level rise (SLR) and its likely consequences such as increasing natural hazards like heavy storms, flooding events and coastal lowland loss by drowning over ... -
Mechanisms of magma emplacement in the upper crust
(2009-05-15)The mechanisms that control magma emplacement in the upper crust are characterised by brittle failure of the host rock and subject to the influence of magma. This thesis is a compilation ... -
Metamorphic fluids at extreme pressure conditions and their significance for element transfer in subduction zones
(2017-05-15)The present study provides a comprehensive geochemical dataset on ultra-/high pressure (UHP/HP) eclogites and enclosed, fluid-deposited metamorphic veins. It targets to broaden our understanding of the nature and extent ... -
Microbial alteration of geochemical proxies in finegrained carbonate sediments during early diagenesis
(2021-07-27)Fine-grained carbonate sediments play a crucial role in the global carbon cycle and are an exceptional record of past environmental conditions. Major paleoenvironmental constraints, derived from stable isotope and trace ... -
Microbial metabolisms and calcification in freshwater biofilms
(2008-04-18)In this study, biofilms of two CO2-degassing karst-water creeks in Germany, which attain high calcite supersaturation during their course downstream, were investigated with regard to the effects of microbial activity ... -
Microbial sulfate reduction in the tissue of the cold-water sponge Geodia barretti (Tetractinellida, Demospongiea)
(2003-06-12)Metabolic rates, community structure and the chemical micro-environment of sulfate-reducing bacteria (SRB) within the tissue of the boreal demosponge Geodia barretti were examined, and ... -
Microstructure of Gas Hydrates in Sedimentary Matrices
(2016-06-22)Gas hydrates (GH) are found worldwide in marine sediments and permafrost regions. The detection and quantification of gas hydrates present in marine sediments is crucial for safe oil and gas extraction, seafloor stability ... -
Mikrobielle Diversität an diffusen Quellen des Mittel-Atlantischen Rückens
(2010-11-30)The deep sea floor forms largest associated ecosystem on earth. With it´s numerous ecological niches such as mud-volcanoes, cold seeps and hot and low-temperature influenced vents it could ... -
Mineralogical, Petrophysical and Economical Characterization of the Dimensional Stones of Uruguay; Implications for Deposit Exploration
(2012-06-05)Dimensional stones are known since the ancient world as noble mineral resources and have been used for the construction of magnificent pieces of art and architecture that were built to endure. Some examples are the Pyramids ... -
Modellierung der vegetativen Produktivität zur Bewertung der Landdegradation im ariden und semi-ariden südlichen Afrika
(2014-01-23)Dry regions as the arid southern Africa are, on the one hand, strained by unfavourable climatic conditions. On the other hand, intensive land use as rangeland and for livestock farming leads to additional encroachment of ... -
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
