A Room of One’s Own : Weiblichkeit, Schreiben und kollektive Erfahrung in Elena Ferrantes Tetralogie L’amica geniale (2011-2014) und Annie Ernaux’ Le…
2021
With her famous suggestion to «give her [the woman] a room of her own and five hundred a year, let her speak her mind» from 1929, Virginia Woolf verbalized a core issue of female writing by hinting at the socioeconomic circumstances and domestic obligations of most women – valid at her times, but still today. Both Elena Ferrante and Annie Ernaux discuss, in their respective novels, the topics of being women in the particular sociocultural land-scape (in Italy and, respectively, in France) after World War II and up to these days, the themes of marriage and motherhood, employment and especially (female) authorship. This article aims to show in a close reading of both Ferrante and Ernaux that …
Contre l'autonomie et la clôture du texte : formes et ambiguïtés de la fiction moderniste européenne : (1910-1939)
2014
Although it has been a key concept of literary criticism in the English-speaking world for more than a half-century, modernism remains a relatively misunderstood notion in France, owing to its proximity to somewhat close concepts such as modernity and avant-garde, which it only partially overlaps. The concept is relevant to experimentation in all literary genres, but this study focuses on the novel, with texts by James Joyce, André Gide, Ramón Gómez de la Serna and Virginia Woolf. Those have often been mischaracterized by literary critics as either mimetic novels — though more realistic than realist novels — or more frequently as emblematic of the self-referential text, as defined by the do…
Photodegradation of Toluene, m-Xylene, and n-Butyl Acetate and Their Mixtures over TiO2 Catalyst on Glass Fibers
2012
The abatement of typical paint solvent compounds as individuals and in mixtures was carried out in an annular TiO2 supported reactor, for concentrations up to 900 mg C m–3. Two different fiberglass supports were compared, and the catalyst supported over a fiber mat showed better performance, with a lower pressure drop (>35% of reduction) and a slightly higher removal efficiency (about 2%) than that supported over glass wool. For every target compound in the whole range of relative humidity studied (4–75%), the photocatalytic activity increased with the air water content. The removal of the compounds in the binary and ternary mixtures was depressed, even >90% for toluene, compared with indiv…
Artesanos emprendedores en la industria textil. Del taller al mercado. El caso del pelaire contestano Bernat Martí (1469-1482)
2014
El presente trabajo analiza la función de un sector del artesanado en el desarrollo y la consolidación de las comunidades pañeras del interior valenciano durante la segunda mitad del siglo XV. Tomando como referencia las comarcas del interior-sur del País Valenciano (la Vall d’Albaida, l’Alcoià y el Comtat, con pequeñas ciudades pañeras como Ontinyent, Alcoi y, especialmente, Cocentaina, donde centraremos nuestro estudio), se analiza cómo un pequeño grupo de artesanos tendía a centralizar y gestionar la actividad textil local mediante su participación directa en el mercado de la lana, tintes y aceite, también mediante el control de las fases de acabado del paño (tundido, abatanado, tintado)…

A Form for Writing 20th Century Loss: Aesthetics of Absence in Virginia Woolf’s Jacob’s Room
2021
Considerada la seva primera novel·la modernista, Jacob’s Room (1922) de Virginia Woolf seria recordada per les seves tecniques experimentals per a contar la historia de Jacob, qui va morir a la Primera Guerra Mundial. La construccio del que es en el fons del seu personatge mes misterios ofereix una resposta diferent a les realitats canviants de la guerra i serveix com manera literaria de dol que busca no tant consolar com preservar i transmetre l’absencia provocada per les perdues de la Gran Guerra. Aqui es presenta una analisis de l’estetica de l’absencia a l’obra de Woolf, i s’afirma que anticipa preocupacions posteriors al tractar experiencies de violencia de masses en la literatura. De …
Characterization of Pigments from <i>Malus domestica</i> Leaves for Wool Dyeing
2021
The study will present results of chemical analysis of mass spectrometry, evaluating the content of pigments in M. domestica leaves dyeing solution and in dyed woollen yarn nowadays. Yarn was dyed with fresh leaves of M. domestica tree. Before dyeing the yarn was treated with potassium aluminium sulphate mordant. Dyestuffs from the yarn were extracted in compliance with modified hydrochloric method of hydrolysis. Extracts were analysed by ultra high-performance liquid chromatography coupled with a diode array detector and mass spectrometry (UHPLC-DAD-MS) for identification of the pigments. Phytochemical screening of dyeing solution of the M. domestica leaves showed presence of dihydrochalco…
Influence of cerium content and heat treatment on Ce:YAG@glass wool nanostructures
2019
The paper reports the influence of cerium content and heat treatment on composition, structural features and optical properties of nanostructures constituted by a layer of Ce:YAG nanoparticles on glass wool (Ce:YAG@GW). The Ce:YAG@GW nanostructures were obtained embedding the glass wool (GW) in a gel-like precursor and calcining at 800 and 900 °C. Gel-like precursor of urea glass route (UGR) method has been used to prepare both nanostructures and Ce:YAG nanoparticles prepared as references. Structural properties were investigated by using X-ray diffraction (XRD) and infrared spectroscopy (IR). Results showed that the composition of the final products strongly depends both on the cerium cont…
Layered dry envelope insulated with sheep wool-lime mix
2014
This poster describes the results of a research aimed to design and assess a new layered envelope component that might be implemented on buildings of the Mediterranean area, in order to improve the energy efficiency and the environmental sustainability. These goals have been achieved by means of the use of local and natural building materials or arising from renewable resources. In particular, thermal insulating has been realize utilizing a mix of natural and mineral materials, obtaining a biocomposite with comparable building physics and mechanical properties to commonly used building materials. Among natural materials, the sheep wool was chosen since it is, on the hand, a waste to exploit…
MODELING OF A TiO2-COATED QUARTZ -WOOL PACKED-BED PHOTOCATALYTIC REACTOR
2010
A fixed-bed, photocatalytic laboratory reactor aimed to degrade pollutants from water streams was designed and built. Quartz wool coated with a thin film of TiO2 was employed as the reactor filling. The photocatalyst was placed in the reactor forming a loose packing to guarantee the intimate contact among reactants, photons, and the photocatalytic surface. This reactor was employed to study the photocatalytic decomposition of a model pollutant (formic acid). A reactor–radiation–reaction model was developed, which was comprised of the reactor mass balance, radiation model, and kinetic model for the degradation of formic acid. The local superficial rate of photon absorption, which was necessa…
