-
(2004)Partial ring currents during the main phase of a geomagnetic storm cause a longitudinal asymmetry in the magnetic field at the earth’s surface at low and mid latitudes. The horizontal component of the magnetic field obtained ...

RIPHEAN SEDIMENTARY SEQUENCES OF THE EASTERN AND NORTHEASTERN MARGINS OF THE EASTERN EUROPEAN CRATON (2002)The Riphean history of depositional basins in the study region can be divided into Early-Middle Riphean and Late Riphean phases. Throughout the Riphean, clastic material was supplied chiefly from eastern regions of the ...
-
(2004)Extensive methane hydrate layers are formed in the near-surface sediments of the Cascadia margin. An undissociated section of such a layer was recovered at the base of a gravity core (i.e. at a sediment depth of 120 cm) ...

RIVER FLOW FORECASTING: USE OF PHASE-SPACE RECONSTRUCTION AND ARTIFICIAL NEURAL NETWORKS APPROACHES (2002)The use of two non-linear black-box approaches, phase-space reconstruction (PSR) and artificial neural networks (ANN), for forecasting river flow dynamics is studied and a comparison of their performances is made. This is ...
-
(2001)An important problem in hydrologic science is understanding how river flow is influenced by rainfall properties and drainage basin characteristics. In this paper we consider one approach, the use of mass exponents, in ...
-
(2004)Rivers are largely responsible for shaping the Earth's continental landscapes. River patterns, the spatial arrangements of channels in the landscape, are determined by slope and structure. At site and sector scale, channel ...
-
(2004)Several satellite techniques have been proposed to monitor events related to seismic and volcanic activity. A selfadaptive approach (RAT, Robust AVHRR Techniques) has recently been proposed which seems able to recognise ...
-
(2001)The instrumental measurement results of the residual shifts and deformations of rocks massif under the action of underground nuclear explosions are presented. The main attention is paid to the problems of deformations ...
-
(2005)The dilation of rock under shear gives rise to detectable effects both in laboratory experiments and in field observations. Such effects include hardening due to reduction in pore pressure and asymmetrical distribution of ...
-
(2003)An idea to consider rock textures from a geostatistical viewpoint is suggested. Mineral grains are coded by indicator functions. Four metrics are shown of interest for petrographic applications. The simplest one is used ...
-
(2003)Detailed rock magnetic investigations, grain size determination and X-ray diffraction were carried out on loess and buried soils of the last glacial-interglacial cycle from Kurtak, southern Siberia. The susceptibility and ...
-
(1988)Tectonic faults consist of water-saturated rocks crushed and crumbled into gravel and sand fractions, thus facilitating a hydraulic connection between the water-bearing zone and all other rocks till the ground surface. ...
-
(2006)Rock avalanches are known to behave in extraordinary ways unlike other landslides, and their deposits in part reflect their unusual physical behavior. Recent experiments in granular physics suggest that many phenomena and ...
-
(1992)A detailed investigation was made of the typomorphic and chemical characteristics of the rock-forming minerals in norite-diorite intrusions in the Voronezh crystalline massif. The rocks of the intrusions are characterised ...
-
(2003)The computer-assisted physicochemical modeling of hydrogeochemical processes that occur in systems of sedimentary and crystalline rocks with water has been done for the following variables: the weight ratio of the reacted ...
-
(2005)Based on the high correlation between species richness in sigmodontine rodents and temperatures, we propose a new model in order to quantify past climates. Because of the close phylogenetic relationship and the tooth ...
-
(2001)Two isolated molars, the holotypes of Asiaparamys shevyrevae NESSOV, 1987b and Kazygurtia clivosa NESSOV, 1987b from the latest Paleocene Dzhylga 1 a locality are restudied, and an additional molar of A. shevyrevae from ...
-
(1999)New data are reported on the geologic setting, structural relations, and composition of calcsilicate metasomatites (rodingites) found, in association with alkali-ultramafic volcanics, in the northern Valaginsky Range, ...
-
(2001)Preface Rodinia and the Mesoproterozoic earth–ocean system www.elsevier.com/locate/precamres We could hardly introduce this volume without mentioning the now infamous words of our respected colleague, Roger Buick, who, in ...
-
(1989)We have shown that the conditions of extrusion of deep-sea lavas on the sea floor are such that the makeup of their quenched flows preserves some structural characteristics of their endogene state and of the processes ...
