Mantle Convection Patterns Reveal the Mechanism of the Red Sea Rifting
(Tectonics, 2020)We present a new model of the stress state and present-day tectonics of the Red Sea Rift (RSR) based on an instantaneous geodynamic mantle flow model. The initial density and viscosity variations in the mantle are derived ... -
Mapping leaf area index over semi-desert and steppe biomes in kazakhstan using satellite imagery and ground measurements
(EARSeL eProceedings, 2009)Maps of peak seasonal leaf area index (LAI) were produced using the Normalised Difference Vegetation Index (NDVI) from SPOT VEGETATION (VEG) satellite at 1 km resolution over a large region in the semi-arid zone of Kazakhstan. ... -
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 ... -
Mass-transport deposits and reservoir quality of Upper Cretaceous Chalk within the German Central Graben, North Sea
(International Journal of Earth Sciences, 2015)The architecture of intra-chalk deposits in the ‘Entenschnabel’ area of the German North Sea is studied based on 3D seismic data. Adapted from seismic reflection characteristics, four types of mass-transport deposits (MTDs) ... -
Mathematische Grundlagen in Biologie und Geowissenschaften - Kurs 2004/2005
(Universtätsverlag Göttingen, 2010)Der Band führt den Grund- und Aufbaukurs der Mathematischen Grundlagen für Biologie und Geowissenschaft zusammen und stellt zahlreiche neue Übungsaufgaben vor. Die vorliegende TEX-Bearbeitung der Vorlesung und der ... -
Mechanical Modeling of Pre‐Eruptive Magma Propagation Scenarios at Calderas
(Journal of Geophysical Research: Solid Earth, 2023-02-24)Simulating magma propagation pathways requires both a well‐calibrated model for the stress state of the volcano and models for dike advance within such a stress field. Here, we establish a framework for calculating ... -
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 ... -
Mechanism of Uranium Removal from the Aqueous Solution by Elemental Iron
(Journal of Hazardous Materials, 2006)The effectiveness of elemental iron (Fe0) to remove uranium (U) from the aqueous phase has been demonstrated. While the mitigation effect is sure, discrepancies in the removal mechanism have been reported. The objective ... -
Mega-monsoon variability during the late Triassic: Re-assessing the role of orbital forcing in the deposition of playa sediments in the Germanic Basin
(Sedimentology, 2019)The formation of the supercontinent Pangaea during the Permo–Triassic gave rise to an extreme monsoonal climate (often termed ‘mega-monsoon’) that has been documented by numerous palaeo-records. However, considerable debate ... -
Mega‐scale glacial lineations formed by ice shelf grounding in the Canadian Beaufort Sea during multiple glaciations
(Earth Surface Processes and Landforms, 2021-05-05)Mega‐scale glacial lineations formed by the raking of ice shelves across the seafloor have been reported from multiple polar regions. Here, we present the first evidence of continental slope situated buried lineations in ... -
Metallic Iron Filters for Universal Access to Safe Drinking Water
(CLEAN - Soil, Air, Water, 2009) -
Metallic iron for environmental remediation: Back to textbooks
(Fresenius Environmental Bulletin, 2012) -
Metallic iron for environmental remediation: learning from electrocoagulation.
(Journal of hazardous materials, 2010-03-15)The interpretation of processes yielding aqueous contaminant removal in the presence of elemental iron (e.g. in Fe(0)/H(2)O systems) is subject to numerous complications. Reductive transformations by Fe(0) and its primary ... -
Metallic iron for environmental remediation: learning from the Becher process.
(Journal of hazardous materials, 2009-09-15)Metallic iron (Fe(0)) is a moderately reducing agent that has been reported to be capable of reducing many environmental contaminants. Reduction by Fe(0) used for environmental remediation is a well-known process to organic ... -
Metallic iron for environmental remediation: the long walk to evidence
(2013-06-25)The science of metallic iron for environmental remediation is yet to be established. The prevailing theory of the Fe 0 /H 2 O system is characterized by its inability to fully rationalize the concept that holds up the ... -
Metallic iron for safe drinking water worldwide
(Chemical Engineering Journal, 2010)A new concept for household and large-scale safe drinking water production is presented. Raw water is successively filtered through a series of sand and iron filters. Sand filters mostly remove suspended particles (media ... -
Metallic iron for water treatment and environmental remediation: A handout to young researchers
(Fresenius Environmental Bulletin, 2015)The premise of this research note is that current research on metallic iron (Fe0) for environmental remediation and water treatment has started on a biased basis. Before expecting experienced researchers to correct flawed ... -
Metallic Iron for Water Treatment: A Critical Review
(CLEAN - Soil, Air, Water, 2013)Water treatment with metallic iron (Fe0) is still based on the premise that Fe0 is a reducing agent. An alternative concept stipulates that contaminants are removed by adsorption, co-precipitation and size-exclusion in a ... -
Metallic iron for water treatment: A knowledge system challenges mainstream science
(Fresenius Environmental Bulletin, 2011)A knowledge system (KS) is a knowledge that is unique to a given group of persons. This form of knowledge may have a local or natural origin and is linked to the community that has produced it. On the contrary, the core ... -
Metallic iron for water treatment: Healing a research community
(Journal of New Developments in Chemistry, 2014)Despite two decades of intensive research on using metallic iron (Fe0) for environmental remediation and water treatment, basic concerns about their efficiency still prevail. This communication presents the basic idea of ...
