(2001)We recently published the results of a study of volatiles evolved during coalification (Kopp et al.,.2000) based on the loss of CH4, H2O, and CO. At that time, the loss of CO2 was not modelled because low-rank lignites and ...
-
(1998)The cell walls of bacteria are known to adsorb a variety of metals, and thus they may control metal mobilities in many low-temperature aqueous systems. In order to quantify metal adsorption onto bacterial surfaces, recent ...
-
(2001)A comparison has been made between the visual observations of surface oil and four satellite-borne Synthetic Aperture Radar (SAR) images taken during the Sea Empress oil spill in February 1996. Whilst the basic oil slick ...
-
(1991)We present a simple virial-type extension to the modified Redlich-Kwong (MRK) equation for calculation of the volumes and fugacities of H2O and CO2 over the pressure range 0.001–50 kbar and 100 to 1400°C (H2O) and 100 to ...
-
(2001)The model developed in this study simulates the contamination of overland flow by soil chemicals that reside near its surface during a surface runoff event. The model includes mass-balance equations for both water flow and ...
-
(2002)The near-Earth magnetic field is due to sources in Earth's core, ionosphere, magnetosphere, lithosphere, and from coupling currents between ionosphere and magnetosphere and between hemispheres. Traditionally, the main field ...
-
(2001)The Tunka basin was initiated during Oligocene, under transtensional regime (normal-sinistral) as shown by large-scale structures and geomorphology. Nevertheless, a preliminary analysis of the most recent deformations ...
-
(2004)In previous papers, we investigated via Monte Carlo simulation the order-disorder behavior of an individual octahedral phyllosilicate sheet, with respect to two-species systems Al/Fe, Al/Mg, and Fe/Mg, and some three-species ...
-
(2003)Atomistic modelling techniques are used to study the rate-determining steps that limit diffusion of oxygen in forsterite. The activation energies for diffusion parallel to all three crystallographic axes by the vacancy and ...
-
(2000)A freeze-drying technique for cutting thin-sections of soft sediments without disturbance is used to study several Lake Baikal sedimentary microstructures. Image analysis methodology is applied to selected thin-sections. ...
-
(2004)The surface of a crystal in equilibrium with solute-bearing fluid generally has a composition that differs from that of the bulk crystal. If the crystal is growing, the surface composition may be “captured” by the newly ...
-
(2002)Hydraulic data defining the dune:antidune transition in fine gravel are compared with potential flow theory, and information is drawn from published experiments and field-based studies. Attention is given to both transitional ...
-
(1999)Available surface complexation models for birnessite required the inclusion of bidentate bonds or the adsorption of cation-hydroxy complexes to account for experimentally observed H+/Mm+ exchange. These models contain ...
-
(2004)Forty-six miniature plate tectonic reconstructions are presented that can be assembled into a "flipbook" that illustrates the movement of the continents since the Late Precambrian, 750 m.yr. ago. Six principal lines of ...
-
(1998)The paper considers the first results of investigation of the cores obtained by drilling in Lake Baikal on the top of the underwater Akademichesky Ridge in 1996. Two boreholes, one to a depth of 300 m, and the other to a ...
-
(2002)We use a strain-rate-dependent visco-plastic rheology in a finite element model to investigate the effects of crustal rheology and thermal structure on the development of normal faults in 2-D extending lithosphere. Strain-rate ...
-
(2001)A method to represent fracture networks in a continuum model is evaluated by an application to the Aspo Hard Rock Laboratory (HRL). The basic approach of the method is to first generate a fracture network, based on data ...
-
(2002)The spaceborne gravity field missions CHAMP, GRACE and GOCE, to be realized in the coming years, will improve our knowledge of the Earth's gravity field in the short, medium and long wavelength parts. Nevertheless, it is ...
-
(2004)Simulation of subsurface heterogeneity is important for modeling subsurface flow and transport processes. Previous studies have indicated that subsurface property variations can often be characterized by fractional Brownian ...
-
(2001)A counterpropagation fuzzy-neural network (CFNN) is the fusion of a neural network and fuzzy arithmetic. It can automatically generate the rules used for clustering the input data. No parameter input is needed, because the ...
