Testing Metallic Iron Filtration Systems for Decentralized Water Treatment at Pilot Scale
(Water, 2015)There are many factors to consider for the design of appropriate water treatment systems including: cost, the concentration and type of biological and/or chemical contamination, concentration limits at which contaminant(s) ... -
Testing the suitability of metallic iron for environmental remediation: Discoloration of methylene blue in column studies
(Chemical Engineering Journal, 2013)A new method to correlate intrinsic reactivity and treatability efficiency of metallic iron (Fe0) was evaluated. A 2.0 mg L-1 methylene blue (MB) solution was used in gravity fed column experiments. The intrinsic reactivity ... -
Testing the Suitability of Zerovalent Iron Materials for Reactive Walls
(Environmental Chemistry, 2005)Zerovalent iron (ZVI) has been proposed as reactive material in permeable in-situ walls for contaminated groundwater. An economically feasible ZVI reactive wall requires cheap but efficient iron materials. From an uranium ... -
Texture asymmetries as shear sense indicators in naturally deformed mono- and polyphase carbonate rocks
(Textures and microstructures, 1999)The microstructural and quantitative texture analyses of a naturally deformed calcite mylonite, a dolomite mylonite and a dolomitic calcite mylonite reveal different texture asymmetries for comparable deformation conditions. ... -
Textures in pure shear deformed rock salt
(Textures and microstructures, 1995)Texture formation in pure shear deformed rock salt has been studied by neutron diffraction. The textures developed are comparable to those of rolled face-centered cubic metals with high stacking fault energy. At room ... -
Textures of paragneisses from the KTB drilling site, Ne Bavaria (FRG)

The @hydrogeology of the Barossa Basin, South Australia
(Department of Water, Land and Biodiversity Conservation, Adelaide, SA2002)The Barossa Basin is a complex hydrogeological environment containing a sedimentary aquifer system surrounded and underlain by a dual porosity fractured rock aquifer. The hydraulic relationship between the fractured rock ... -
The Alichur Dome, South Pamir, Western India–Asia Collisional Zone: Detailing the Neogene Shakhdara–Alichur Syn-collisional Gneiss-Dome Complex and Connection to Lithospheric Processes
(Tectonics, 2020)Neogene, syn-collisional extensional exhumation of Asian lower–middle crust produced the Shakhdara–Alichur gneiss-dome complex in the South Pamir. The <1 km-thick, mylonitic–brittle, top-NNE, normal-sense Alichur shear ... -
The Aral Sea - a palaeoclimate archive
(Univ. Potsdam, 2006)Der Aralsee ist ein intrakontinental gelegenes endorheisches Gewässer fernab von ozeanischen Einflüssen, welches ein exzellentes sedimentäres Archiv für hochauflösende Paläoklimastudien in Zentralasien darstellt. In der ... -
The behaviour of consolidated volcanic tuffs: weathering mechanisms under simulated laboratory conditions
(Environmental geologyEnvironmental geology, 2008)Five volcanic tuffs ranging from dacitic tuffs of Hungary to rhyolite, phonolite and basaltic tuffs of Germany were consolidated under laboratory conditions. Prior to consolidation an anti-hygro, a hydrous consolidant, ... -
The birth of the Alps: Ediacaran to Paleozoic accretionary processes and crustal growth along the northern Gondwana margin
(International Journal of Earth Sciences, 2021-05-10)New whole-rock geochemical and coupled U–Pb and Lu–Hf LA-ICP-MS zircon data of metasedimentary rocks of the Austroalpine, South Alpine and Penninic basement domains are presented, to disentangle the pre-Variscan tectonic ... -
The bowing potential of granitic rocks: rock fabrics, thermal properties and residual strain
(Environmental Geology, 2007)The bowing of natural stone panels is especially known for marble slabs. The bowing of granite is mainly known from tombstones in subtropical humid climate. Field inspections in combination with laboratory investigations ... -
The Di models method: geological 3-D modeling of detrital systems consisting of varying grain fractions to predict the relative lithological variability for a multipurpose usability
(Bulletin of Engineering Geology and the Environment, 2021-12-21)The coexistence of a wide variety of subsurface uses in urban areas requires increasingly demanding geological prediction capacities for characterizing the geological heterogeneities at a small-scale. In particular, detrital ... -
The effect of air pollution on stone decay: the decay of the Drachenfels trachyte in industrial, urban, and rural environments—a case study of the Cologne, Altenberg and Xanten cathedrals
(Environmental Earth Sciences, 2013)Severe stone deterioration is evident at the Cologne cathedral. In particular, the “Drachenfels” trachyte, which was the building material of the medieval construction period, shows significant structural deterioration as ... -
The effect of asymmetric dune roughness on tidal asymmetry in the Weser estuary
(Earth Surface Processes and Landforms, 2021-06-10)The bed of estuaries is often characterized by ripples and dunes of varying size. Whereas smaller bedforms adapt their morphological shape to the oscillating tidal currents, large compound dunes (here: asymmetric tidal ... -
The effect of formation processes on the frequency of palaeolithic cave sites in semiarid zones: Insights from Kazakhstan
(Geoarchaeology, 2022-04-05)Central Asian caves with Palaeolithic deposits are few, but they provide a rich record of human fossils and cultural assemblages that has been used to model Late Pleistocene hominin dispersals. However, previous research ... -
