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 …
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…

A common biological basis of obesity and nicotine addiction
2013
Contains fulltext : 128630.pdf (Publisher’s version ) (Open Access) Smoking influences body weight such that smokers weigh less than non-smokers and smoking cessation often leads to weight increase. The relationship between body weight and smoking is partly explained by the effect of nicotine on appetite and metabolism. However, the brain reward system is involved in the control of the intake of both food and tobacco. We evaluated the effect of single-nucleotide polymorphisms (SNPs) affecting body mass index (BMI) on smoking behavior, and tested the 32 SNPs identified in a meta-analysis for association with two smoking phenotypes, smoking initiation (SI) and the number of cigarettes smoked …
Foucault: il potere oltre le regole. Repliche a Celano, Moreso, Segatti e Spena
2020
In questo articolo rispondo alle critiche e ai commenti alla mia ricostruzione della concezione del potere di Michel Foucault proposti da Bruno Celano, José Juan Moreso, Marco Segatti, Alessandro Spena. Mi concentro in particolare sui seguenti aspetti: la connessione fra la nozione foucaultiana di potere e il conflitto; la distinzione fra potere disciplinare, potere governamentale, e potere normativo; la concezione foucaultiana della libertà come autorialità; ciò che Foucault può suggerire riguardo ad alcune “macchie cieche” della teoria del diritto contemporanea.
