Modeling Net Ecosystem Exchange for Grassland in Central Kazakhstan by Combining Remote Sensing and Field Data
(
- Remote Sensing
, 2009)
Carbon sequestration was estimated in a semi-arid grassland region in Central
Kazakhstan using an approach that integrates remote sensing, field measurements and
meteorological data. Carbon fluxes for each pixel of 1 × ...
Simulation of saturated and unsaturated flow in karst systems at catchment scale using a double continuum approach
(
- Hydrology and Earth System Sciences
, 2012-10-30)
The objective of this work is the simulation of
saturated and unsaturated flow in a karstified aquifer using
a double continuum approach. The HydroGeoSphere code
(
Therrien et al.

) is employed to simulate spring ...
Elemental metals for environmental remediation: lessons from hydrometallurgy
(
- 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 ...
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 ...
Nanoscale Metallic Iron for Environmental Remediation: Prospects and Limitations

Microbial fabric formation in spring mounds ("microbialites") of alkaline salt lakes in the Badain Jaran Sand Sea, PR China
(
- Palaios
, 1998)
The large sandy desert of Badnin Jaran Shamo, Inner
Mongolia, has several salt lakes located among megadunes
with crests as high as 400 m. Most of the lakes are hypo- to
hypersaline and alkaline, with pH values between ...
Die geowissenschaftliche Datenbank GeoRef und die Virtuelle Fachbibliothek Geowissenschaften im Vergleich
(2008-04-30)
Die Bibliografische Datenbank GeoRef und die Virtuelle Fachbibliothek GEO-LEO eignen sich bei paralleler Nutzung für eine weitgehend erschöpfende Informationsrecherche im Bereich Geowissenschaften. Während GeoRef im ...
Influence of shape fabric and crystal texture on marble degradation phenomena: simulations
(
- Environmental Earth Sciences
, 2010)
Microstructure-based finite element simulations were used to study the influence of grain shape fabric and crystal texture on thermoelastic responses related to marble degradation phenomena. Calcite was used as an illustrative ...
Porosity and distribution of water in perlite from the island of Milos, Greece.
(
- SpringerPlus
, 2014)
A perlite sample representative of an operating mine in Milos was investigated with respect to the type and spatial distribution of water. A set of different methods was used which finally provided a consistent view on the ...
Schichtenfolge und Oberflächenformen im Winterberggebiete des Elbsandsteingebirges
(TH Dresden, 1928)
Der Kampf der Meinungen um Erosion, Denudation oder Gesteinswechsel ist also noch nicht entschieden und mit den angewandten Methoden nicht zu entscheiden. So mehren sich die Stimmen, die eine Lösung der Fragen, soweit sie ...
