Effect of pumice and sand on the sustainability of granular iron beds for the aqueous removal of CuII, NiII, and ZnII
(CLEAN - Soil, Air, Water, 2013)Current knowledge of the basic principles underlying the design of Fe0 beds is weak. The volumetric expansive nature of iron corrosion was identified as the major factor determining the sustainability of Fe0 beds. This ... -

Optimising the Design of Fe0-Based Filtration Systems for Water Treatment: The Suitability of Porous Iron Composites
(Journal of Applied Solution Chemistry and Modeling, 2013-08-31)This study assessed the functionality of metallic iron (Fe0) filtration systems using porous iron composite (PIC) as an alternative to granular Fe0/aggregate mixtures. The usage of PIC for water treatment has many challenges ... -
Satellite-based monitoring system for assessment of vegetation vulnerability to locust hazard in the River Ili delta (Lake Balkhash, Kazakhstan)
(Journal of Applied Remote Sensing, 2013)The study investigates the overall vulnerability of vegetation in the River Ili delta (Lake Balkhash, Southern Kazakhstan) to locust hazards using correlation between the normalized difference vegetation index data from ... -
Mechanism of uranium fixation by zero valent iron: the importance of co-precipitation
(Uranium in the aquatic environment, 2002)The coprecipitation of U (VI) with iron corrosion products from aqueous solutions by zero valent iron was investigated. The evidence of coprecipitation was demonstrated by conducting experiments with well characterized ... -
Local stresses, dyke arrest and surface deformation in volcanic edifices and rift zones
(ANNALS OF GEOPHYSICS, 2004)Field studies indicate that nearly all eruptions in volcanic edifices and rift zones are supplied with magma through fractures (dykes) that are opened by magmatic overpressure. While (inferred) dyke injections are frequent ... -
Multi-Source Remotely Sensed Data Combination: Projection Transformation Gap-Fill Procedure
(Sensors, 2008)In this work a new gap-fill technique entitled projection transformation has been developed and used for filling missing parts of remotely sensed imagery. In general techniques for filling missing areas of an image break ... -
Modeling the Permeability Loss of Metallic Iron Water Filtration Systems

Lebend- und Totengemeinschaften von Süßwassermollusken des Tegeler Sees - ein Beitrag zur Beurteilung seines ökologischen Zustandes
(25 Jahre Paläontologie FU Berlin, 1989) -
Review of Available Products of Leaf Area Index and Their Suitability over the Formerly Soviet Central Asia

Quantitative Analysis of the Misorientation Distribution After the Recrystallisation of Tensile Deformed Copper Single Crystals
(Textures and microstructures, 1991)Recrystallisation experiments in tensile deformed <100>- and <111>-oriented single crystals of high purity copper yielded very accurate information about the orientations of recrystallised grains and deformation microstructure. ... -
Lattice preferred orientation as an indicator of a complex deformation history of rocks
(Textures and microstructures, 1999)The deconvolution of the deformation history of rocks is one of the main goals of texture analysis in geology. The frequent observation that the macroscopic structures are obliquely oriented with respect to the margins of ... -
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 ... -
Neutron texture analysis of melt-textured YBCO bulk samples
(Textures and microstructures, 1999)Neutron texture measurements on YBCO bulk samples show a very sharp texture of the superconducting phase YBa2Cu3O7-x with half-widths of less than 5°. Even with a rather coarse measurement grid of only 722 points per ... -
Processes of Contaminant Removal in Fe0-H2O Systems Revisited: The Importance of Co-Precipitation
(The @open environmental journal, 2007)The mechanism of aqueous contaminant removal by elemental iron (Fe0) materials (e.g., in Fe0-H2O systems) has been largely discussed in the iron technology literature. Two major removal mechanisms are usually discussed: ... -
Comments on "Mechanism study of nitrate reduction by nano zero valent iron" by Hwang et al. [J. Hazard. Mater. (2010), doi:10.1016/j.jhazmat.2010.10.078].

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. ... -
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, ... -
Marble bowing: comparative studies of three different public building facades
(Environmental geologyEnvironmental geology, 2008)The veneer cladding of the Oeconomicum (OEC, Göttingen), the State Theatre of Darmstadt (STD, Darmstadt) and of the State and University Library (SUB, Göttingen) is characterised by pronounced bowing after a short time of ... -
Hydrogen incorporation in enstatite in the system MgO-SiO2-H2O-NaCl
(Contributions to mineralogy and petrologyContributions to mineralogy and petrology, 2008)The incorporation of hydrogen in enstatite in a hydrous system containing various amounts of NaCl was investigated at 25 kbar. The hydrogen content in enstatite shows a clear negative correlation to the NaCl-concentration ... -
