Monitoring the optical turbulence in the surface layer at Dome C, Antarctica, with sonic anemometers
Eric Aristidi, Jean Vernin, Eric Fossat +11
The optical turbulence above Dome C in winter is mainly concentrated in the first tens of meters above the ground. Properties of this so-called surface layer (SL) were investigated…
Crossover from quasi-static to dense flow regime in compressed frictional granular media
Florent Gimbert, David Amitrano, Jérôme Weiss
We investigate the evolution of multi-scale mechanical properties towards the macroscopic mechanical instability in frictional granular media under multiaxial compressive loading.…
Damage-cluster distributions and size effect on strength in compressive failure
Lucas Girard, Jerome Weiss, David Amitrano
We investigate compressive failure of heterogeneous materials on the basis of a continuous progressive damage model. The model explicitely accounts for tensile and shear local dama…
A Comparison Of New Calculations Of The Yearly 10Be Production In The Earths Polar Atmosphere By Cosmic Rays With Yearly 10Be Measurements In Multiple Greenland Ice Cores Between 1939 And 1994 - A Troubling Lack Of Concordance Paper #2
W. R. Webber, P. R. Higbie, C. W. Webber
We have compared the yearly production rates of 10Be by cosmic rays in the Earths polar atmosphere over the last 50-70 years with 10Be measurements from two separate ice cores in G…
Modeling of the formation of short-chain acids in propane flames
Frédérique Battin-Leclerc, A. A. Konnov, J. L. Jaffrezo +1
In order to better understand their potential formation in combustion systems, a detailed kinetic mechanism for the formation of short-chain monocarboxylic acids, formic (HCOOH), a…
Submm/FIR astronomy in Antarctica: Potential for a large telescope facility
Vincent Minier, V. Minier, L. Olmi +14
Preliminary site testing datasets suggest that Dome C in Antarctica is one of the best sites on Earth for astronomical observations in the 200 to 500 micron regime, i.e. for far-in…
To better understand the formation of short-chain acids in combustion systems
Frédérique Battin-Leclerc, A. A. Konnov, J. L. Jaffrezo +1
Our study aims at a better control and understanding of the transfer of a complex [DNA supercoiled plasmid - dodecyltrimethylammonium surfactant] layer from a liquid-vapour water i…
A2163: Merger events in the hottest Abell galaxy cluster I. Dynamical analysis from optical data
S. Maurogordato, A. Cappi, C. Ferrari +7
We present a detailed optical analysis of the galaxy cluster A2163 based on new multicolor wide field imaging and medium-to-high resolution (R~2000) spectroscopy. While X-ray obser…
On the critical character of plasticity in metallic single crystals
Thiebaud Richeton, Patrik Dobron, Frantisek Chmelik +2
Previous acoustic emission (AE) experiments on ice single crystals, as well as numerical simulations, called for the possible occurrence of self-organized criticality (SOC) in coll…
Dislocation avalanche correlations
Jerome Weiss, M. -Carmen Miguel
Recently, mechanical tests on ice as well as dislocation dynamics simulations have revealed that plastic flow displays a scale-free intermittent dynamics characterized by dislocati…
Deformation of grain boundaries in polar ice
Gael Durand, Francois Graner, Jerome Weiss
The ice microstructure (grain boundaries) is a key feature used to study ice evolution and to investigate past climatic changes. We studied a deep ice core, in Dome Concordia, Anta…
Intermittent dislocation flow in viscoplastic deformation
M. -Carmen Miguel, Alessandro Vespignani, Stefano Zapperi +2
The viscoplastic deformation (creep) of crystalline materials under constant stress involves the motion of a large number of interacting dislocations. Analytical methods and sophis…
Complexity in dislocation dynamics: model
M. -Carmen Miguel, Alessandro Vespignani, Stefano Zapperi +2
We propose a numerical model to study the viscoplastic deformation of ice single crystals. We consider long-range elastic interactions among dislocations, the possibility of mutual…
Water Ice, Silicate and PAH Emission Features in the ISO Spectrum of the Carbon-rich Planetary Nebula CPD-56 8032
Martin Cohen, M. J. Barlow, R. J. Sylvester +5
Combined ISO SWS and LWS spectroscopy is presented of the late WC-type planetary nebula nucleus CPD-56 8032 and its carbon-rich nebula. The extremely broad coverage (2.4-197 micron…
