Le corps au carrefour de l’intertextualité et de la rhétorique [PDF]

open access: yes, 2005
Ce texte examine l’isotopie du corps en relation avec l’écriture, en mettant au jour les instances à l’oeuvre dans le roman africain contemporain derrière le double mouvement de fragmentation et de rassemblement.

Localization and Delocalization During Seismic Slip

open access: yesGeophysical Research Letters, Volume 51, Issue 22, 28 November 2024.
Abstract The thickness of a seismic slip layer controls style and rate of rupture propagation, frictional heating, weakening, and energy budget of earthquakes. Slip layer thickness changes dynamically with feedbacks between temperature rise, roughness, damage, and fluid pressurization. Natural faults have complex slip histories, ambiguating which layer

Périglaciaire du Canada : idées nouvelles et perspectives globales [PDF]

open access: yes, 1961
Periglacial conditions which occur in Canada have been studied recently. Most of the research has been so jar limited in scope (mostly patterned ground and permafrost), undertaken for practical purposes (v.g.

Seismic Response of Hectometer‐Scale Fracture Systems to Hydraulic Stimulation in the Bedretto Underground Laboratory, Switzerland

open access: yesJournal of Geophysical Research: Solid Earth, Volume 129, Issue 11, November 2024.
Abstract We performed a series of hydraulic stimulations at 1.1 km depth in the Bedretto underground laboratory, Switzerland, as part of an overall research strategy attempting to understand induced seismicity on different scales. Using an ultra‐high frequency seismic network we detect seismic events as small as Mw < −4, revealing intricate details of ...

Experimental Investigations of Air Entrainment in Transition and Skimming Flows down a Stepped Chute: Application to Embankment Overflow Stepped Spillways [PDF]

open access: yes, 2001
Stepped spillways have been used for about 3,500 years. The last few decades have seen the development of new construction materials, design techniques and applications : e.g., embankment overtopping protection systems.

Late Cenozoic metamorphic evolution and exhumation of Taiwan [PDF]

open access: yes, 2007
The Taiwan mountain belt is composed of a Cenozoic slate belt (Hsuehshan Range units, HR, and Backbone Slates, BS) and of accreted polymetamorphic basement rocks (Tananao Complex, TC).

Standardisation, calibration and correlation of the Kübler-index and the vitrinite/bituminite reflectance: an inter-laboratory and field related study [PDF]

open access: yes, 2018
A multiple inter-laboratory calibration with illite Kübler-Frey-Kisch "crystallinity” index and related standards is presented and compared with CIS standards used in the last two decades in very low-grade metamorphic studies.

2-D non-periodic homogenization of the elastic wave equation: SH case [PDF]

open access: yes, 2010
International audienceIn the Earth, seismic waves propagate through 3-D heterogeneities characterized by a large variety of scales, some of them much smaller than their minimum wavelength.

Instrumental evidence of normal mode rock slope vibration [PDF]

open access: yes, 2017
A unique field experiment was performed to constrain the seismic response of a large, potentially unstable rock slope in the southern Swiss Alps. Small-aperture seismic arrays were deployed to record ambient vibrations both inside and outside of the ...

Overflow Characteristics of Circular Weirs : Effect of Inflow Conditions [PDF]

open access: yes, 1998
The most common types of weirs are the broad-crested weir, the sharp-crested weir, the circular-crested weir and nowadays the ogee crest weir. Advantages of the cylindrical weir shape include the stable overflow pattern, the ease to pass floating debris,
