A two-dimensional inversion method was applied to the COPROD-2S2 dataset, which consists of apparent resistivity, phase, and magnetic transfer functions at 33 sites over 3.5 decade period band. The modeling pr...
In the last two Magnetotelluric Data Interpretation Workshops (MT-DIW) the participants were asked to model the Kayabe magnetotelluric dataset, a dense (100 m) grid of thirteen lines, with thirteen stations in...
Extensive EM studies have been made in the Ukraine during the last 40 years and a set of reliable results have been received. Data from 3000 Magnetotelluric soundings are presented as maps of effective apparen...
It is well known that equatorial electrojet (EEJ) currents can significantly affect the geomagnetic variations. However, in a recent study (Padilha et al., 1997) it was observed that magnetotelluric (MT) sound...
Diagrams from electromagnetic data that were recorded at Muntele Roşu Observatory during the periods from December 1996 to January 1997, and December 1997 to September 1998 were plotted. The times when Vrancea...
The interpretation of actual geophysical field data still has a problem for obtaining a unique solution. In order to investigate the groundwater potentials in Saqqara archaeological area, vertical electrical s...
There exists a number of models that account for the deep structure of the Sayan-Baikal province on the basis of different geophysical data. The models based on magnetotelluric soundings differ from those obta...
Initially, two 2D models are presented in order to emphasize the possible placement of the Trans-European Suture in the rooted zone of the Eastern Carpathians’ Flysch Nappes System. Then, a conclusive review o...
The method proposed is based on the Arrenius’ equation, that links electrical conductivity of solids with an enthalpy of activation, is studied and well-known distributions of temperature, pressure and electri...
The use of Mohr circles into magnetotelluric (MT) intepretation was introduced by Lilley (Lilley, 1976). By plotting Zxx-rotated versus Zxy-rotated (real and imaginary parts) important information on the conducti...
A reconnaissance MT survey was conducted in the southern portion of the Sao Francisco Sedimentary Basin, Brazil, for mapping the subsurface structure. The objective was to provide a regional model and in helpi...
We carried out sixty-four MT and GDS soundings in the eastern Swiss Alps to obtain information on the electrical conductivity distribution. One of the main findings is an anomalous directional behaviour of the...
For models having moderate departures from the basic distortion model (from the so called “principal superim-position” model, that is where local three-dimensional and regional two-dimensional structures are s...
Using the staggered grid full domain 3D modeling schemes of various accuracies have been developed. This study focuses on the second order finite difference method with the 13-point rule for meshes extending i...
A computational method for automatic 3D MT modelling is described. Making use of a recent publicly available forward algorithm, our method allows unattended search for a 3D conductivity model. The geometry of ...
A modified synthetic method for phenolicβ-O-4 lignin substructure model dimers was developed involving protection of the phenolic hydroxyl group of acetophenons with benzoyl chloride, bromination with 4-dimethyla...
To investigate the bleaching mechanism, a lignincarbohydrate complex (LCC) model compound, a vinyl ether-type lignin model dimer, and a hexeneuronic acid model compound were treated with dilute sulfuric acid o...
The purpose of this study was to reveal the effects of various levels of mat-moisture content (m.m.c.) and the closed-press system for making single- or three-layer particleboard on the density profile, thickn...
The storage modulus and the mechanical loss tangent of untreated, extracted, and sugar- impregnated canes (Arundo donax L.) were measured over a temperature range of −150° to 0°C at low frequencies. Two relaxatio...
