Assessing accuracy of gas-driven permeability measurements: a comparative study of diverse Hassler-cell and probe permeameter devices
gas-driven permeability measurements diverse Hassler-cell probe permeameter devices
2015/1/6
Permeability is one of the most important petrophysical parameters to describe the reservoir properties of sedimentary rocks, pertaining to problems in hydrology, geothermics, and hydrocarbon reservoi...
First observational evidence for the CO2-driven origin of Stromboli's major explosions
CO2-driven origin Stromboli's major explosions
2014/12/31
We report on the first detection of CO2 flux precursors of the till now unforecastable "major" explosions that intermittently occur at Stromboli volcano (Italy). An automated survey of the crater plum...
Decoupling of ground level pressures observed in Italian volcanoes: are they driven by space weather geo-effectiveness?
Atmospheric pressure Space weather Sun storm Volcanoes
2015/8/17
Investigations on correlation drops between near-ground atmospheric pressures measured at sea level and at higher altitudes on Italian volcanoes have been carried out. We looked for perturbations of t...
Wind driven capillary-gravity waves on Titan’s lakes: Hard to detect or non-existent?
Titan Saturn Satellites Radar observations Infrared observations
2014/4/8
Saturn’s moon Titan has lakes and seas of liquid hydrocarbon and a dense atmosphere, an environment conducive to generating wind waves. Cassini observations thus far, however, show no indication of wa...
Bistable attractors in a model of convection-driven spherical dynamos
self-consistent MHD dynamos thermal convection oscillatory dynamos Fluid Dynamics
2012/4/20
The range of existence and the properties of two essentially different chaotic attractors found in a model of nonlinear convection-driven dynamos in rotating spherical shells are investigated. A hyste...
A dynamo driven by zonal jets at the upper surface: applications to giant planets
giant planets upper surface
2011/9/1
We present a dynamo mechanism arising from the presence of barotropically unstable zonal jet currents in a spherical shell. The shear instability of the zonal flow develops in the form of a global Ros...
Intergyre transport in a wind-driven,quasigeostrophic double gyre:An application of lobe dynamics
Intergyre transport wind-driven,quasigeostrophic double gyre lobe dynamics
2009/11/12
We study the flow obtained from a three-layer, eddy-resolving quasigeostrophic ocean circulation model subject to an applied wind stress curl. For this model we will consider transport between the nor...

Centrifugally driven convection in the rotating cylindrical annulus with modulated boundaries
Centrifugally driven convection cylindrical annulus modulated boundaries
2009/11/12
The effect of sinusoidally modulated conical end boundaries on convection in a rotating cylindrical annulus is investigated theoretically and experimentally. A quasiperiodic time dependence of convect...
Geometric aspects of HF driven Langmuir turbulence in the ionosphere
Geometric aspects HF Langmuir turbulence ionosphere
2009/11/11
The geometric aspects of HF-generated Langmuir turbulence in the ionosphere and its detection by radars are theoretically discussed in a broad approach, including local modelling (damped and driven Za...
Phase-space holes due to electron and ion beams accelerated by a current-driven potential ramp
Phase-space holes electron and ion beams current-driven potential ramp
2009/11/11
One-dimensional open-boundary simulations have been carried out in a current-carrying plasma seeded with a neutral density depression and with no initial electric field. These simulations show the dev...
Intermittent chaos driven by nonlinear Alfvén waves
Intermittent chaos nonlinear Alfvén waves
2009/11/11
We investigate the relevance of chaotic saddles and unstable periodic orbits at the onset of intermittent chaos in the phase dynamics of nonlinear Alfvén waves by using the Kuramoto-Sivashinsky (KS) e...
