-
(2003)The transport of particle-associated bacteria during rain events in karst waters has been investigated. In this aim, we studied the correlations between water turbidity and enumerations of sessile (attached) and planktonic ...
-
(2001)A new model is proposed to numerically simulate transfer of melt between microscopic pores and macroscopic veins in a deforming porous matrix. Matrix rheology is assumed to be visco-elastic. Darcy flow of porous melt through ...
-
(2001)Interambularcral plates of echinoid Heterocentrotus trigonarius, composed of Mg calcite 1 (~14 mol% MgCO3), were heated in three timed series of experiments at 300°C. Dried plate fragments and fragments with added water ...
-
(2004)Samples of Recent–Miocene fish and marine mammal bones from the bottom of the Atlantic and Pacific oceans and Miocene Maikop deposits (Transcaspian region) are studied by the X-ray diffraction (XRD) technique combined with ...
-
(2004)Trend modelling is an important part of natural resource characterization. A common approach to account for a variable with a trend is to decompose it into a relatively smoothly varying trend and a more variable residual ...
-
(2003)We investigate a transformation of magnetic trans- fer functions into the tangential-electric mode part of the impedance tensor in the scope of the plane-wave electromagnetic tensor-VLF method. The transforma- tion, which ...
-
(2001)Based on the seismostratigraphic analysis and geological interpretation of seismic profiling data, three marker surfaces corresponding to structural unconformities and erosion events are defined in the area of the Danube ...
-
(1998)Three main stages related to major transgressive-regressive cycles of the development are recognized in the Late Cenozoic history of the Arctic Ocean: the Miocene-early Pliocene (regressive), late Pliocene-Eopleistocene ...
-
(2004)We present an experimental investigation on the dissolution of uniaxially stressed crystals of NaClO3 in contact with brine. The crystals are immersed in a saturated fluid, stressed vertically by a piston and monitored ...
-
(2003)A closed-form asymptotic solution is derived for the magnetic field of the currents induced by a transient airborne magnetic source in a conductive layer of finite thickness. The conductive layer rests on top of a resistive ...
-
(1998)Flash heating simulation experiments have been performed to determine the effects of heating time, cooling rate, ambient gas fO2, and the sample bulk composition on the extent of Na loss of silicate melts and the implications ...
-
TRANSIENT PHENOMENA IN VESICULAR LAVA FLOWS BASED ON LABORATORY EXPERIMENTS WITH ANALOGUE MATERIALS (2004)Realistic lava flow models require a comprehensive understanding of the rheological properties of lava under a range of stress conditions. Previous measurements have shown that at typical eruption temperatures lavas are ...
-
(2003)The ultrafast transient photoluminescence of impact silica-rich glasses and nanostructured opals is investigated at the (sub)nanosecond time scale. Spectral and temporal data were acquired with a high-resolution streak ...
-
(1997)We demonstrate qualitatively that frictional instability theory provides a context for understanding how earthquakes may be triggered by transient loads associated with seismic waves from near and distance earthquakes. We ...
-
(2001)The local structural environment around Ni(II) in a series of crystalline model compounds and K-Ni-, Na-Ni-, and Ca-Ni-silicate glasses and melts has been evaluated by using high-resolution Ni K-edge XANES spectroscopy and ...
-
(2001)The local coordination environment around Ni(II) in a series of sodium trisilicate (NS3) and albitic (ALB) glasses has been evaluated by using high-resolution XANES and anharmonic EXAFS spectroscopies. The glasses contain ...
-
(2001)We present quantitative modeling results of the dynamic interplay of passive extension and active convective thinning of the mantle lithosphere beneath intracontinental rift zones investigating the relative importance of ...
-
(1989)One promising area of theoretical research on metasomatism is the development of a macrokinetic model based on reversible reactions. The present paper describes a numerical investigation of a model of bimetasomatism in ...
-
(1998)The pattern and style of mantle convection govern the thermal evolution, internal dynamics, and large-scale surface deformation of the terrestrial planets. In order to characterize the nature of heat transport and convective ...
