Elemental metals for environmental remediation: lessons from hydrometallurgy
Crane, R. A.;
(Fresenius Environmental Bulletin, 2012)
In the mining industry, the separation of economically valuable metals from gangue materials is a well established process. As part of this field, hydrometallurgy uses chemical fluids (leachates) of acidic or basic pH ... -

(E&G – Quaternary Science Journal; Vol.39, No. 1)Arbeiten für die Geologische Landesaufnahme und ergänzende Untersuchungen ermöglichten es, die Reste der pleistozänen Sand-Kies-Terrassen der Weser im Abschnitt Gieselwerder-Hehlen zu gliedern. Aufgrund der Höhenlage ihrer ... -
Elster-Löß und Holstein-Ton von Northeim (Hann.)
(E&G – Quaternary Science Journal; Vol.11, No. 1)Unter dem Holstein-Interglazialton der Ziegelei Kerrl in Northeim, das zur Zeit relativ gut aufgeschlossen ist, wurde elstereiszeitlicher Löß aufgefunden. Da ein sicherer Nachweis eines Lösses solch hohen Alters noch nicht ... -
Elsterzeitliche (Anglian) Eisdynamik in East Anglia
(E&G – Quaternary Science Journal; Vol.42, No. 1)Gefügeuntersuchungen in Aufschlüssen in East Anglia haben gezeigt, daß während der Elster-Vereisung (Anglian) ein Eisvorstoß aus dem Nordseebecken von einem Vorstoß britischen Eises erst aus westlicher, später aus nördlicher ... -
Emil Johannes Wiechert (1861-1928) – Initiator der DGG-Gründung und Erster Vorsitzender 1922 sowie Ehrenvorsitzender 1925
(Mitteilungen der Deutschen Geophysikalischen Gesellschaft; Band 2; 2022)Aus Anlass des 100. Jahrestages der Gründung der Deutschen Geophysikalischen Gesellschaft im Jahre 1922 in Leipzig erschien im Verlag Edition am Gutenbergplatz Leipzig das Buch „Wiechert, Mintrop & Co. – Die 24 Gründungsväter ... -
Empirical assessment of rockfall and debris flow risk along the Karakoram Highway, Pakistan
; ; ; ; (Natural Hazards, 2021-02-15)
The Karakoram Highway links north Pakistan with southwest China. It passes through unique geomorphological, geological and tectonic setting. This study focused 200-km-long section of the highway starting from Besham until ... -
Empirical relations of rock properties of outcrop and core samples from the Northwest German Basin for geothermal drilling
(Geothermal Energy Science, 2014)Information about geomechanical and physical rock properties, particularly uniaxial compressive strength (UCS), are needed for geomechanical model development and updating with logging-while-drilling methods to minimise ... -
Empirische Feldstudien über elektromagnetische Emissionen in Gesteinen unter aktiven Krustenspannungen
(11. Symposium "Tektonik, Struktur- und Kristallingeologie", 2006-03)In den vergangenen Jahren wurden von den Mitgliedern unseres Departments mehrere Feldstudien über elektromagnetische Emissionen in tektonisch aktiven Regionen durchgeführt. Die Untersuchungsgebiete lagen in Südspanien, ... -
Emulator-based global sensitivity analysis for flow-like landslide run-out models
; ; (Landslides, 2021-08-13)
Landslide run-out modeling involves various uncertainties originating from model input data. It is therefore desirable to assess the model’s sensitivity to these uncertain inputs. A global sensitivity analysis that is ... -
Enabling Climate Change Adaptation in Coastal Systems: A Systematic Literature Review
; ; ; (Earth's Future, 2023-08-16)
Abstract Climate change poses increasingly severe risks for coastal ecosystems and coastal ...

Energetic ion composition and acceleration mechanisms in the magnetosphere of Jupiter
(Univ. Zugl.: Braunschweig, 2006)Based on the first 15 orbits of the Galileo spacecraft the composition of the energetic ion population of the Jovian magnetosphere has been studied for the first time on a global scale. More specific, three different types ... -
Energetic particles in the Jovian magnetosphere and their relation to auroral emissions
(Univ. Zugl.: Braunschweig, 2005)This thesis discusses the relation between the energetic particle characteristics measured by Galileo in the inner to middle Jovian magnetosphere, and the auroral emissions observed by the Hubble Space Telescope. The thesis ... -
Energetically consistent scale-adaptive stochastic and deterministic energy backscatter schemes for an atmospheric model
; ; (Quarterly Journal of the Royal Meteorological Society, 2019)
Current climate models still suffer from many biases which are partly due to excessive subgrid-scale dissipation. Here we systematically develop energetically consistent stochastic energy backscatter (SEB) and deterministic ... -
Energy Conversion by Magnetic Reconnection in Multiple Ion Temperature Plasmas
; ; ; (Geophysical Research Letters, 2023-06-26)
Abstract Magnetic reconnection is a process that converts magnetic energy into kinetic energy, ...

Energy Flux Observations in an Internal Tide Beam in the Eastern North Atlantic
; ; ; ; ; ; ; (Journal of Geophysical Research: Oceans, 2019)
Low-mode internal waves propagate over large distances and provide energy for turbulent mixing when they break far from their generation sites. A realistic representation of the oceanic energy cycle in ocean and climate ... -
Energy‐dispersive X‐ray stress analysis under geometric constraints: exploiting the material's inherent anisotropy
(Journal of Applied Crystallography, 2023-04-01)Two data evaluation concepts for X‐ray stress analysis based on energy‐dispersive diffraction on polycrystalline materials with cubic crystal structure, almost random crystallographic texture and strong single‐crystal ... -
Engineering geological rock mass characterisation of granitic gneisses based on seismic in-situ measurements
(GFZ, Helmholtz-Zentrum, 2004)For deep underground excavations, the prediction of locations of small-scale geotechnical hazardous structures such as faults is nearly impossible when exploration is restricted to surface based methods. Therefore, for ... -
