-
(1988)The large-scale thermal convection that causes lithospheric plates to move generates in the upper part of each mantle cell a thermal boundary layer that travels at a constant speed without distortion. There is a strong ...
-
(2004)The method of generation of self-oscillations in rocks is developed here. Self-oscillations arise as a result of direct and inverse mechanoelectric transformations without an external generator. Laboratory experiments were ...
-
(2004)The flow of groundwater during a pumping test experiment is responsible for a measurable electrical field at the ground surface owing to the electrokinetic coupling between the Darcy velocity and the electrical current ...
-
(1990)We know that self-similarity and a hierarchical organization are typical of the structure of complex natural dynamic systems. In the course of an empirical analysis of dynamic processes in liquid, solid and gaseous natural ...
-
(1987)The present paper discusses the vertical structure of the principal thermocline in another important dynamic zone, a zonally-oriented large-scale jet stream. The zone of the Trade Wind Drift is a typical example of such a ...
-
(1987)In the time domain, a deviation of the emission of seismic energy from that predicted by the independent trial process has been proved on various scales; this deviation is the result of interaction between earthquakes. On ...
-
(2004)The P–T partition function in statistical thermodynamics can be used to derive semi-empirical formulations of the Gibbs free energy G for minerals and fluids. Parameterization of these equations includes simultaneous ...
-
(1998)Significant differences in fission-track annealing kinetics indicate that chlorapatites may give older fission-track ages and record different thermal histories to those derived from co-existing fluorapatites which have ...
-
(1998)Interstratified illite-smectites (I/S) and illite-smectite-vermiculites (ISV) representing both hydrothermal and diagenetic transformations and having different degrees of structural order were investigated for cis-trans ...
-
(2003)This work studies a methodology starting from georadar data that allows a semiquantitative evaluation of massive rock quality. The method is based on the concept that in good quality rock, most of the energy is transmitted, ...
-
(2002)This report extends previous work (. Chlorophyll degradation during senescence and death. Organic Geochemistry 29, 1233-1251.) in which we detailed type-I (alteration) and -II (destruction) degradation of chlorophyll with ...
-
(2003)The deformation of marker horizons across slip surfaces can lead to the development of several types of flanking structures. The development of such structures was investigated using a numerical model to simulate the flow ...
-
(2003)A nonlinear regression method is used to calculate the hydraulic parameters of a stream-aquifer system using pumping test data. Five parameters, including the horizontal hydraulic conductivity (Kx), aquifer anisotropy (Ka), ...
-
(2001)This paper reviews the basic concepts of sensitivity analysis and points out their limitations. A case is then made for logarithmic sensitivity. The magnitude of logarithmic sensitivity alone does not determine the accuracy ...
-
(2002)Field-scale transport of reactive solutes depends on spatially variable physical and chemical soil properties. The quantitative importance of physical and chemical parameters required for the prediction of the field-scale ...
-
(2002)The sensitivity distributions of different electrode configurations are computed for both a homogeneous resistivity distribution and a model consisting of two vertical zones of homogeneous resistivity. The inner zone around ...
-
(2002)Variability with respect to model input data is recognised as a potential source of uncertainty in model predictions. The aim of this study is to estimate the sensitivity of computed values of water balance terms, in ...
-
(2004)A global carbon-cycle box model forced by an ocean-general circulation model (OGCM) is used to investigate how different sea-surface reconstructions for the northern North Atlantic Ocean (Nordic Seas) for the Last Glacial ...
-
(2002)Long-term carbon cycle models and independent proxies indicate that the atmospheric CO2 concentration was substantially higher in the Mesozoic and early Tertiary than now. The responses of tree growth to a high CO2 environment ...
