La Riforma in Inghilterra: Elisabetta e i 39 Articoli di religione della Chiesa Anglicana
2019
The aim of this article is to underline the doctrinal peculiarities of Anglicanism through examination of the 39 Articles of religion. Unlike other coeval protestant confessions of faith, the genesis of the 39 Articles was eminently dictated by political reasons, that is to say the reinforcement of the English monarchy through the pursuit of religious unity in the Country
Le genre des bris de machines : violence et mécanisation à l’aube de l’ère industrielle (Angleterre-France, 1750-1850)
2013
Les bris de machines constituent un type de violence recurrent en Angleterre et en France au debut de l’ere industrielle. Ce type de violence contestataire a ete peint essentiellement sous les traits d’une pratique masculine, impliquant le triomphe d’une conception virile des rapports sociaux et des conflits du travail. Loin d’etre marginales ou invisibles, les femmes sont pourtant bien presentes dans ces conflits, a la fois comme auxiliaires des hommes mais aussi comme actrices de plein droit insurgees contre les machines qui portent atteinte a la production domestique et a leur mode de vie. En examinant le genre des bris de machines, il s’agit a la fois de suivre comment les machines requ…
Democracia, república y federación en época isabelina. Una aproximación al proyecto federal de Roque Barcia Martí
2016
Este artículo propone una aproximación al proyecto federal defendido por Roque Barcia Martí a mediados del siglo XIX, prestando especial atención a los principios teóricos y los argumentos -inspirados por una fuerte religiosidad- que sustentan su propuesta. Más allá de la estricta cuestión territorial o de las plasmaciones jurídico-políticas concretas, la federación aparece como una solución global a las tensiones de la modernidad que el Estado liberal no sabía solucionar. En este planteamiento, el campo político se configura como un espacio de humanización que reclama, como punto de partida, la necesaria reformulación política del Estado para transformar la sociedad y, potencialmente, la h…
Study of the hydrolysis of lithium hydride
2015
The hydrolysis of LiH at room temperature and under low water vapor pressure (PH2O < 10 hPa) is investigated by thermogravimetry and FTIR spectroscopy with low sample mass. Then, to be closer to industrial conditions, hydrolysis of LiH is studied by manometry either in closed (adjustable PH2O) or open (constant PH2O) system using larger amounts of sample and heavy water. Products of the reaction are characterized by X-ray diffraction and FTIR spectroscopy. The first set of experiments show that the mechanism of hydrolysis starts with the formation of lithium oxide Li2O. Then, when the oxide layer is sufficiently thick, the hydrolysis reaction is followed by the formation of lithium hydroxid…
L’ibridazione interspecifica: evidenze e limiti di un fenomeno ancora da comprendere
2013
L’interesse per l’aspetto evoluzionistico dell’ibridazione interspecifica è cresciuto negli ultimi anni, a giudicare dalla mole di articoli e review pubblicati sull’argomento. Fili conduttori di questi lavori sono la considerazione dell’ibridazione avvenuta e la conseguente ricerca delle evidenze che la dimostrano, siano esse morfologiche o genetiche: quasi mai l’evento di ibridazione viene messo in discussione, neppure quando le specie coinvolte sono caratterizzate da sbilanciamenti aneuploidi molto forti. Generalmente, l’ibridazione tra specie riconosciute come distinte è impedita dall’innescarsi di meccanismi d’isolamento pre e postzigotici. Questa incompatibilità ci porta a mettere in d…
Conduit dynamics and post explosion degassing on Stromboli: A combined UV camera and numerical modeling treatment.
2016
Abstract Recent gas flux measurements have shown that Strombolian explosions are often followed by periods of elevated flux, or “gas codas,” with durations of order a minute. Here we present UV camera data from 200 events recorded at Stromboli volcano to constrain the nature of these codas for the first time, providing estimates for combined explosion plus coda SO2 masses of ≈18–225 kg. Numerical simulations of gas slug ascent show that substantial proportions of the initial gas mass can be distributed into a train of “daughter bubbles” released from the base of the slug, which we suggest, generate the codas, on bursting at the surface. This process could also cause transitioning of slugs i…
Study of a chromia-forming alloy behavior as interconnect material for High Temperature Vapor Electrolysis
2011
In High Temperature Vapor Electrolysis (HTVE) system, the materials chosen for the interconnectors should have a good corrosion behaviour in air and in H2-H2O mixtures at 800°C, and keep a high electronic conductivity over long durations as well. In this context, the first goal of this study was to evaluate a commercial ferritic alloy (the K41X alloy) as interconnect for HTVE application. Oxidation tests in furnace and in microbalance have therefore been carried out in order to determine oxidation kinetics. Meanwhile, the Area Specific Resistance (ASR) was evaluated by Contact Resistance measurements performed at 800°C. The second objective was to improve our comprehension of chromia-formin…
Reply to the “Comment by Delmelle et al. (2013) on ‘Scavenging of sulfur, halogens and trace metals by volcanic ash: The 2010 Eyjafjallajökull erupti…
2014
Abstract With this short communication we address the principal issues raised by Delmelle et al. (2014) in relation to the work of Bagnato et al. (2013) concerning the 2010 eruption of Eyjafjallajokull, Iceland. The principal conclusions of the work of Bagnato et al. (2013) include the observation that protracted gas-aerosol interaction in the plume promotes selective leaching of cation species from ash, with alkalis and Ca (and, among trace elements, Zn and Cu) being more rapidly re-mobilized (and transferred to soluble surface salts) relative to more inert elements (Mg, Ti). They also observed that adsorption onto ash surfaces is a major atmospheric sink of volcanic acidic gases, with 282…
Volatiles in pantellerite magmas: A case study of the Green Tuff Plinian eruption (Island of Pantelleria, Italy)
2013
Abstract The Green Tuff (GT) Plinian eruption, the largest in magnitude at Pantelleria, erupted 3 to 7 km3 DRE of pantellerite magma and a small volume of trachyte. Fifty-nine anorthoclase-hosted melt inclusions from the two basal pumice members were analyzed by FT-IR spectroscopy in order to assess the pre-eruptive H2O content in the pantellerite melt. Microanalytical methods were used to determine major element, Cl, F and S contents. Melt inclusions and glassy groundmasses have a nearly homogeneous pantelleritic composition (peralkaline index = 1.9-2.2) and variable water contents ranging from 1.4 to as high as 4.2 wt %, i.e. much higher than the 1.4 wt % of earlier published studies. The…
LA NORMA LINGÜÍSTICA DEL ESPAÑOL DESDE UNA PERSPECTIVA LEXICOGRÁFICA: NORMA NACIONAL VERSUS NORMA PANHISPÁNICA
2015
La definición de la norma lingüística del español desde una perspectiva lexicográfica plantea dificultades y ha provocado debates intensos. Normalmente se otorga al Diccionario académico un valor normativo en el mundo de habla española, sin embargo no está concebido como estrictamente normativo, ya que da entrada a elementos diversos de carácter vulgar, jergal, etc. Por otra parte, ha sido rechazado como referencia normativa por quienes critican su centralismo o su falta de correspondencia con la situación real del español. Estas actitudes críticas se han expresado con frecuencia en la lexicografía hispanoamericana. Las Academias de la lengua española han dado pasos en los últimos años para…
