Ternary transition metals sulfides in hydrotreating catalysis.

2007

International audience; Pure microcrystalline barium molybdate BaMoO4 and barium tungstate BaWO4 materials were prepared by molten flux reaction using alkali metal nitrates as reaction media. The obtained crystals have rhombic shape and expose mostly (111) crystallographic planes. Their mean size depends on the flux temperature and the nature of the alkali metal cation. Monomeric molybdate and tungstate used as precursors yield target products already at 673 K whereas if polymerized ammonium oxosalts were used, then higher temperatures were necessary to obtain barium salts. The optimal temperature for the preparation of pure crystals with well defined shape was found to be near 773 K. UV–vi…

Los marcos de interpretación de la violencia de género en las televisiones del Estado español. Modelos y tendencias

2012

<p>En los últimos años la violencia de género se ha convertido en un problema social de primera magnitud, cobrando especial atención los medios de comunicación por su responsabilidad en la construcción de realidades sociales. El objetivo de este artículo es analizar el tratamiento informativo de la violencia de género y su papel en la construcción de marcos de interpretación que dotan de significado el concepto de violencia de género. Para ello, se ha aplicado el análisis crítico del discurso a las noticias de cuatro televisiones del Estado español en la semana alrededor del Día Internacional contra la Violencia de Género de 2010.</p>

Integrative analysis of the mineralogical and chemical composition of modern microbialites from ten Mexican lakes: What do we learn about their forma…

2021

International audience; Interpreting the environmental conditions under which ancient microbialites formed relies upon comparisons with modern analogues. This is why we need a detailed reference framework relating the chemical and mineralogical compositions of modern microbialites to the physical and chemical parameters prevailing in the environments where they form. Here, we measured the chemical, including major and trace elements, and mineralogical composition of microbialites from ten Mexican lakes as well as the chemical composition of the surrounding waters. Saturation states of lakes with different mineral phases were systematically determined and correlations between solution and so…

Hacia una propuesta metodológica para el estudio de la atenuación fónica en Es.Var.Atenuación

2017

espanolEl proyecto Es.Var.Atenuacion se interesa por el estudio de la atenuacion pragmatica a nivel linguistico, estructural, enunciativo y situacional, en corpus discursivos del espanol, a fin de reconocer las posibles estrategias atenuantes de un acto comunicativo. Para llevar a cabo el analisis se parte de una ficha de trabajo (Briz y Albelda, 2013. Una propuesta teorica y metodologica para el analisis de la atenuacion linguistica en espanol y portugues.

Dual attachment pairs in categorically-algebraic topology

2011

[EN] The paper is a continuation of our study on developing a new approach to (lattice-valued) topological structures, which relies on category theory and universal algebra, and which is called categorically-algebraic (catalg) topology. The new framework is used to build a topological setting, based in a catalg extension of the set-theoretic membership relation "e" called dual attachment, thereby dualizing the notion of attachment introduced by the authors earlier. Following the recent interest of the fuzzy community in topological systems of S. Vickers, we clarify completely relationships between these structures and (dual) attachment, showing that unlike the former, the latter have no inh…
