-
(2001)Groundwater mounds and hinge lines are important features related to the interaction of groundwater and lakes. In contrast to the transient formation of groundwater mounds, numerical simulations indicate that permanent ...
-
(2001)Accurate prediction of water flow and chemical transport in agricultural soil profiles requires the use of a simulation model that considers the most important physical, hydrological and chemical processes. Two important ...
-
(2001)Bore hole breakout is an important method to measure the orientation of earth stress. For inhomogeneous rocks, actual orientation of break out usually deviates from the minimum compressional stress predicted by idealistic ...
-
(2001)Experiments in area of liquid chemically active jets on destroyed material have shown high efficiency of this process. In order to provide material saving, opportunity for the liquid jets replacement with gas jets has been ...
-
(2001)Oceanic bottom pressure is affected by mass redistribution in the ocean and atmosphere, and it influences gravity field determinations by the new satellite missions CHAMP, GRACE and GOCE from seasonal up to short-period ...
-
(2001)Water-bearing fluids are suggested to result from thermodynamically equilibrium interaction andesite - water in the zone of accumulation of hydrothermal solutions from peripheral magma chambers. Thus, intermediate magma ...
-
(2003)The time domain random walk (TDRW) method has been developed for simulating solute transport in discrete fracture networks. The following transport processes have been considered: advective transport in fractures, hydrodynamic ...
-
(2001)The order-disorder phase transitions in NaNO3 and CaCO3e simulated by molecular dynamics. The simulations are based on the potentials calculated from the Gordon-Kim modified electron gas formalism extended to molecular ...
-
(1999)The evolution of a karst aquifer is modelled taking into account the karst groundwater flow as well as the dissolution kinetics of calcite. In particular, infiltration of water from the epikarst is simulated which controls ...
-
(2002)A new method is proposed for modelling complex X-ray diffraction patterns effectively. The method is based on the calculation of the interference function of the onedimensional disordered crystals with finite thickness. ...
-
SIMULATIONS OF MINERALS USING DENSITY-FUNCTIONAL THEORY BASED ON ATOMIC ORBITALS FOR LINEAR SCALING (2004)The use of quantum mechanics methods within the formalism of density functional theory requires a method to represent the electron wave functions. We compare the use of strictly localized basis functions based on atomic ...
-
(1998)Results of in situ atomic force microscopy (AFM), ex situ AFM, optical microscopy, scanning electron microscopy, energy dispersive spectroscopy, and x-ray diffraction were combined with previous macroscopic investigations ...

SIMULTANEOUS INVERSION FOR MANTLE SHEAR VELOCITY AND TOPOGRAPHY OF TRANSITION ZONE DISCONTINUITIES (2003)Until now, modelling of three-dimensional (3-D) velocity variations in the mantle and topography of the transition zone discontinuities have been considered separately. Velocity models were obtained assuming that the radii ...
-
(1993)Precipitation rates of kaolinite and gibbsite were measured in stirred-flow reactors with a mixed seed substrate of kaolinite plus gibbsite at 80°C and pH 3. Input solutions were supersaturated simultaneously to different ...
-
(2000)Experimental clinopyroxenes synthesized at 850-1500 degrees C and 0-60 kbar in the CMS and CMAS-Cr systems and in more complex lherzolitic systems have been used to calibrate a Cr-in-Cpx barometer and an enstatite-in-Cpx ...
-
(1993)Single crystals of paragenetic garnet (gt), omphacite (cpx) and kyanite (ky) were isolated from an eclogite xenolith from the Zagadochnaya kimberlite, Yakutia (grospydite Z13) and studied by polarized FTIR-microspectrometry ...
-
(2003)We applied laser-ablation inductively coupled plasma-mass spectrometry (LA-ICP-MS) as a new and precise technique for measuring trace elements in benthic foraminifera (Hoeglundina elegans). With this technique, trace element ...
-
(2003)The cooling history of the Acapulco meteorite for >400°C is well established using various chronometers suggesting extremely fast cooling (>1000°C/Ma). In contrast, the thermal history for low temperatures (<400°C) is ...
-
(1997)Stepwise Pb-Pb leaching (PbSL) has been successfully used to date rock-forming silicates directly linked to metamorphic reactions defining a PT path. The two features of PbSL are an increase of precision and a control on ...
