Role of peat organic matter on isotopic composition of most abundant benthic organisms in intertidal habitats of SW Iceland
2008
The transfer of peat organic matter (OM) from tidal pools of upper littoral to downstream rocky shores and its potential incorporation into marine biota were investigated using the stable isotope approach. Samplings were carried out in September 2004 in two SW Icelandic sites (Osar and Hvassahraun), where we selected (1) areas with shores where grass gently declined towards rocks and, on reaching the sea line, formed small tidal peat pools and (2) areas where grass and rocky shores were not contiguous, rather the grass lower limits were several hundreds of meters back from the shore. In both grass and no grass areas, in the intertidal zone, all benthic organisms and all potential OM sources…
Sources of organic matter for inter-tidal consumers in Ascophyllum-shores (Sw Iceland): a multi stable isotope approach.
2007
Stable isotopes were used to examine the origin of organic matter in Icelandic Ascophyllum-based habitats, the role of different organic matters in filling intertidal food webs and the food preferences of the most abundant suspension feeders, grazers and predators. We selected three intertidal sites on the SW coast of Iceland where we sampled in early September 2004, organic matter sources (POM, SOM and most abundant primary producers, A. nodosum and F. vesciculosus) and the most abundant macrofauna species (barnacles, mussels, gastropods, sponge and crabs). Even though the primary production (Ascophyllum-based) was the same at the three study sites, the isotopic composition of common-among…
Análisis del comportamiento de las restauraciones de circona monolítica en comparación con las de metal-cerámica y las de circona-porcelana
2015
1. INTRODUCCIÓN La elección del material a emplear en Prótesis Fija debe hacerse, principalmente, en función de dos propiedades: resistencia y estética. Refiriéndonos al primero de ellos, las coronas ceramometálicas han constituido el patrón de oro. Sin embargo, su defecto es no conseguir el segundo requisito principal que le pedimos a una restauración: estética. En la continua búsqueda del material ideal, irrumpen con fuerza las circonas. 2. MATERIAL Y MÉTODO Para la realización del presente trabajo, fueron preparados 80 discos, todos ellos de 10 mm de diámetro, los cuales se dividieron en cuatro grupos, con 20 especímenes cada uno. En los dos primeros, las muestras constaban de dos capas,…
La influencia de la porcelana china en los estilos artísticos de la cerámica española hasta el siglo XVIII
2023
La porcelana china de exportación ha influido en la manufactura y el desarrollo de la cerámica a nivel mundial, convirtiéndose en una portadora física del intercambio cultural con el resto del mundo, que ha sido emulada y estudiada al mismo tiempo que ha absorbido elementos culturales ajenos, de modo que ha permitido incorporar distintas artes al desarrollo global de la cultura cerámica. Por otra parte, la península Ibérica cuenta con una larga historia en el desarrollo de la cerámica, especialmente desde que la conquista árabe acaecida durante la Alta Edad Media trajo consigo las más avanzadas técnicas de fabricación cerámica y la estética decorativa del mundo islámico, hasta el punto que …
Hacer películas chilenas desde Francia: Marcela Said y Jairo Boisier
2019
Submitting projects to international funds and the subsequent festival tour are obligatory steps for most films that, outside purely commercial circuits, seek distribution and cultural legitimacy beyond their national borders. In this globalized context, European support funds are particularly important. Following the path opened by pioneering scholars (De Valck, Elsaesser, Falicov, Shaw), this article aims to study the transnational networks in which Latin American cinema is currently involved. We address this issue by focussing on the specific case of two Chilean directors based in France: Marcela Said and Jairo Boisier. By doing so, we intend to show how European and particularly French …

Porites corals from Crete (Greece) open a window into Late Miocene (10Ma) seasonal and interannual climate variability
2006
Variations in the biotic composition of marine shallow water carbonates document global climatic changes. However, a discontinuous stratigraphic record and uncertainties regarding the ages limit the significance of shallow water carbonates as palaeoclimatic archives on geological time-scales. Notwithstanding these deficits, the environmental information stored in the skeleton of reef biota is a unique source of information that resolves seasonal to interannual climate variability in geological time. Application of the method to corals from carbonate rocks is usually restricted to the past 130,000yr, because the aragonite skeleton undergoes rapid diagenetic alteration. Consequently, reconstr…
Clastic injection dynamics during ice front oscillations: A case example from Sólheimajökull (Iceland).
2015
18 pages; International audience; Soft-sediment deformation structures are being increasingly used as a tool for reconstructing palaeoenvironments and porewater pressure conditions in glacial settings. However, the potential of hydrofractures and clastic injections in the reconstruction of ice dynamics remains poorly constrained. This paper presents the results of a detailed study of a clastic injection network outcropping in the Sólheimajökull forefield (South Iceland). Sedimentological descriptions are combined with microscopic to macroscopic analyses of clastic injection geometries, sediment-fills, and cross-cutting relationships. The 250 m long and 20 m high exposure observed along the …
Fluid-pressure controlled soft-bed deformation sequence beneath the surging Breiðamerkurjökull (Iceland, Little Ice Age).
2009
16 pages; International audience; The general subject of this paper is subglacial deformation beneath Breiðamerkurjökull, a surging Icelandic glacier. More specifically it discusses the evolution and the role of fluid pressure on the behaviour of subglacial sediments during deformation. During Little Ice Age maximum, the two outcrops studied, North Jökulsarlon (N-Jk) and Brennhola-Alda (BA), were located at 2550 m and 550 m respectively from the front of the Breiðamerkurjökull. Sedimentological analysis at the forefield of the glacier shows thick, coarse glaciofluvial deposits interbedded with thin, fine-grained shallow lacustrine/swamp deposits, overlain by a deformed till unit at N-Jk. BA…
Rewriting Romance in the Second Half of 20th Century in Italy
2013
Many authors in the last century offer us the possibility to look at romance through their rewriting of Italian tradition, but they also offer the possibility to look at rewriting through romance. A systematic examination of every single work would need an article itself. Here the focus is rather on the phenomenon and its implications with tradition and its transformations; and on the intellectual context where they take place. Despite the very core of the poetics of rewriting can be located between the Sixties and the Eighties, these palimpsests go further, into the Nineties. From Calvino, Manganelli and Sanguineti, to Celati, Bufalino and Santagata, we are able to look at different declen…
