Entre arcadia y barbarie. Figuras del campo en el cine de los años 30
2010
Los años veinte fueron, en Europa en general y en América, y a su modo en España, momentos de explosión de las urbes. La arquitectura, las artes, el diseño, la fotografía y, por supuesto, el cine participaron de la celebración extática. De Paul Strand y Charles Sheeler a Dziga Vertov, de Walter Ruttmann a Alberto Cavalcanti, de Roben Flaherty a Herman Weinberg, no hubo capital que no tuviera su elogio. En consecuencia, el campo no representó la cresta de ese movimiento por la modernidad: anclado en tipología y mitos arcaicos, encarnación inmóvil de la autenticidad, heroico apenas en algunas manifestaciones, como el esfuerzo que sugerían los llamados Bergfilme alemanes (filmes de montaña), e…
Fabrication and electro-optical characterization of Ruthenium-based Dye-Sensitized Solar Cells
2015
In this paper, we measure the main photoelectrical parameters of Dye Sensitized Solar Cells (DSSCs) based on ruthenium complexes at different irradiance levels, incident wavelengths, temperatures and hours of light soaking
Experimental characterization of Ruthenium-based Dye Sensitized Solar Cells and study of light-soaking effect impact on performance
2016
In this paper, we present an experimental investigation on the performance of Ruthenium-based Dye Sensitized Solar Cells (DSSCs) at different irradiance levels, incident wavelengths and hours of illumination. In particular, the measurements have been aimed at studying the performance variation due to light soaking effect since this phenomenon has noteworthy practical implications, such as stability tests of DSSCs. Our results show that the short circuit current density, the open circuit voltage and the conversion efficiency η increase with the hours of light soaking. Finally, the observed phenomenon is reversible, and thus the performance decreases again when the cell is kept in the dark.
Characterization of thin film CIG(S,SE)2 submodules using solar simulator and laser beam induced current techniques (Versione estesa)
2015
In this work, the electrical and optical characterization of CIG(S, Se)2 sub-modules using both a solar simulator equipment and the Laser Beam Induced Current (LBIC) technique is presented. By using the solar simulator and a proper set-up, the electrical parameters of the modules at varying irradiance and temperatures are determined. In addition, the LBIC measurements are carried out to analyze the 2D photocurrent uniformity of the modules at two different wavelengths. Dispersion values of extracted parameters can be very useful for practically tuning the modelling stage at device/module level.
Characterization of Thin Film CIG(S,Se)2 submodules using Laser Beam Induced Current Technique
2015
Nowadays, an important class of thin film solar cells consists of CuInGa(S,Se)2 (CIGSSe) solar cells, i.e., composed of Copper, Indium, Gallium, Sulfur and Selenide. Thanks to their electrical and optical properties and to the technological development, thin film integrated photovoltaic modules have nowadays obtained relatively good values of efficiency. In this work, we have performed the electrical and optical characterization of a CIGSSe sub-module by using both a solar simulator equipment and the Laser Beam Induced Current (LBIC) technique.

Corporate tax cuts and business-friendly policies in the UK - A review of electoral arguments during the 2015 legislative campaign
2016
The stance toward big business was a heated topic during Britain’s 2015 legislative campaign that led to the triumphal, albeit slightly unexpected, reelection of David Cameron, as Prime Minister. More profoundly, it raises the issue of the economic impact of corporate tax cuts and the nature of business-friendly policies in the UK. Firstly, we investigate the electoral arguments on both sides of the political spectrum. These discussions are framed within the overarching approach known as supply-side economics, which has been prevalent in English-speaking countries since the neoliberal revolution in the late 1970s. Secondly, we put forward the idea that widening inequalities, as suggested re…
Expresión proteica de p53 y proliferación celular en leucoplasias orales
2005
Objetivos: Conocer la expresión proteica de las alteraciones genéticas que se producen en las etapas precoces de la cancerización del campo de cavidad oral en nuestro medio. Estudiar la proliferación celular mediante Ki-67 y la expresión de la proteína p53 para valorar si las alteraciones en la expresión proteica de estos marcadores suceden de forma secuencial a través de las distintas etapas en la cancerización del campo de la cavidad oral. Material y métodos: Se realizó un estudio mediante técnicas de inmunohistoquímica sobre 53 pacientes que presentaron lesiones de leucoplasia oral, atendidos por el Servicio de O.R.L del Hospital Universitario de Salamanca, desde 1.990 hasta 2000. Se inc…
The British Press Responds to the Liberation of the Concentration Camps
2011
Following the liberation of Western concentration camps, especially Buchenwald (11 April) and Bergen-Belsen (15 April), newspapers in Europe reported a story of cruelty that seemed to surpass every other atrocity story they had told before. This chapter will examine how the liberation news was published in the mainstream British papers. It is now well known that the liberation of the camps hardly helped the British public to comprehend the true nature of the Nazi genocide.1 However, what concerns us here is to go beyond the argument according to which the dominant liberal discourse in Britain was principally responsible for influencing British understanding of the Holocaust. Instead, this c…
Porta orientale, Parma. Limen urbano e sguardo infinito
2011
Il contributo fa riferimento alla presentazione del progetto di Andrea Sciascia, "Porta orientale, Parma", nell'ambito del 9° Convegno nazionale ad inviti "Identità dell’Architettura Italiana", svoltosi presso l'Università degli Studi di Firenze, Dipartimento di Architettura. Il progetto propone una grande piastra solcata trasversalmente da un’area verde, che costituisce l’elemento ordinatore del disegno generale nella rilettura delle tracce del paesaggio rurale governato dalla memoria delle tracce della centuriazione. La piastra ritrova la sua unità solo lungo il fronte della via Emilia, dove una torre sottolinea l’angolo sul bordo sud-est del recinto dell’area ex Salamini. È questo un pun…
