Alla ricerca dell’autonomia politica: lingua e letteratura come strumenti per l’affermazione di una minoranza
Sciascia e Camilleritra Racconto e Cronaca Sociale
In “a very strange guide” of Bahia, Jorge Amado proposes a self-definition that can also be used to explain an aspect, not secondary, of the narrative work by Leonardo Sciascia and Andrea Camilleri: “They tell what they lived, the hero of their books is the people, their goal is to achieve the future”. Sciascia, to talk about his first work (which will be entitled Le parrocchie di Regalpetra), uses the term “cronaca” (that appears in the title of the chapter “Cronache scolastiche”): chronicles of a village – Regalpetra – a place the writer knows very well, in its social and historical physiognomy, which he can write about, because he lived it. Camilleri, in the same way, not only in historical, civil, and crime novels, but also in writings of minor narrative structure, when not occasional, as may be the pages that describe some aspects of Porto Empedocle, in which the author explicitly qualifies herself as a witness (“I saw from my terrace”). Both Italian writers tell what they know – each with their own narrative strategy and with their own world view – and constitute the people as the hero of their books. More complex is to say if they consider (as the Brazilian writer) that the goal to be achieved is the future, and what it would mean, for one and the other, the idea of future: which its political and social tone is, which (and several) moods compose the concept, destined to innervate vivid narrative pages.Nella “guida ben strana” di Bahia, Jorge Amado propone un’autodefinizione che può essere impiegata anche per spiegare un aspetto, non secondario, dell’opera narrativa di Leonardo Sciascia e Andrea Camilleri: “Racconta quel che sa per averlo vissuto, eroe dei suoi libri è il popolo, la sua meta da raggiungere è l’avvenire”. Per dire del suo primo scritto (che prenderĂ il titolo Le parrocchie di Regalpetra), Sciascia impiega il termine “cronaca” (che compare nel titolo del capitolo “Cronache scolastiche”): cronache di un paese – Regalpetra – che lo scrittore conosce a fondo, nella fisionomia storica e sociale, e in relazione al quale può scrivere in quanto sa per averlo vissuto. Allo stesso modo Camilleri, nei romanzi storici e civili come in quelli polizieschi, ma anche in scritti di minore strutturazione narrativa, se non addirittura occasionali, come possono essere le pagine che descrivono alcuni aspetti di Porto Empedocle, implicitamente o esplicitamente si qualifica come testimone (“vidi dal mio balcone”). Anche i due scrittori italiani raccontano quello che sanno, dunque, e – ciascuno con la propria strategia narrativa e con la visione del mondo che gli appartiene – costituiscono il popolo quale eroe dei loro libri. PiĂą complesso dire se (come lo scrittore brasiliano) ritengano che la meta da raggiungere sia l’avvenire e che cosa poi significhi, per l’uno e per l’altro, l’idea di avvenire: di quali tonalitĂ politiche e sociali si colori, da quali (e diversissimi) umori sia composto quel concetto, destinato a innervare vivide pagine narrative.No “bem um estranho guia” da Bahia, Jorge Amado propõe uma autodefinição que tambĂ©m pode ser utilizada para explicar um aspecto nada secundário da obra narrativa de Leonardo Sciascia e Andrea Camilleri: “Narra o que sabe por tĂŞ-lo vivido, herĂłi de seus livros Ă© o povo, sua meta a alcançar Ă© o porvir”. Para falar de seu primeiro escrito (que se intitulará Le parrocchie di Regalpetra), Sciascia utiliza o termo “cronaca” (que aparece no tĂtulo do capĂtulo “Cronache scolastiche”): crĂ´nicas de um lugarejo – Regalpetra – que o escritor conhece a fundo, em sua fisionomia histĂłrica e social, e com relação ao qual pode escrever, pois sabe por tĂŞ-lo vivido. Da mesma maneira, Camilleri – nos romances histĂłricos e civis, assim como nos policiais, mas tambĂ©m em escritos de menor estruturação narrativa, se nĂŁo mesmo ocasionais, como podem ser as páginas que descrevem alguns aspectos de Porto Empedocle – implĂcita ou explicitamente se qualifica como testemunha (“vi de meu terraço”). TambĂ©m os dois escritores italianos contam o que sabem, portanto, e – cada qual com a prĂłpria estratĂ©gia narrativa e com a visĂŁo do mundo que lhes pertence – constituem o povo como herĂłi de seus livros. Mais complexo Ă© dizer se (como o escritor brasileiro) consideram que a meta a ser alcançada seria o porvir, e o que afinal significaria, para um e para outro, a ideia do porvir: de que tonalidades polĂticas e sociais se colore, de quais (e diversĂssimos) humores Ă© composto o conceito, destinado a estimular vĂvidas páginas narrativas
Isole e continenti, letterature e identitĂ : attraversando le frontiere del Sud
The Mediterranean Sea is the liquida frontiera which has become an archetype reproduced in literature and in films. It is a border in the sense of a transit place, a meeting place that fosters dialogues between peoples coming from different realities, each of them speaking their own language, and pursuing economical and political interests that are often in contrast.
Such variety has not always been considered an enrichment; on the contrary, it has undergone a process of schematization, resulting in a repertoire of stereotypes and images produced by an external and judging perspective.
We are indebted to literature – to Giovanni Verga, Federico De Roberto, Luigi Capuana, Luigi Pirandello, Giuseppe Tomasi di Lampedusa, Leonardo Sciascia, Gesualdo Bufalino, Andrea Camilleri – for providing us with a more truthful narration which reproduces the phenomenon in all its complexity, including the description of the present process of reciprocal adjustment.Il Mediterraneo è la liquida frontiera in cui si è creato un archetipo riprodotto nei racconti letterari e nei film.
Frontiera intesa come luogo del transito, dell’incontro e del colloquio fra popoli che provengono da realtà diverse, parlano ciascuno la propria lingua, hanno interessi economici e politici non di rado in contrasto. Tale ricchezza è stata spesso schematizzata in un repertorio di stereotipi e di immagini prodotte da uno sguardo esterno e giudicante.
Dobbiamo invece alla letteratura – a Giovanni Verga, Federico De Roberto, Luigi Capuana, Luigi Pirandello, Giuseppe Tomasi di Lampedusa, Leonardo Sciascia, Gesualdo Bufalino, Andrea Camilleri – una più veridica narrazione che restituisce il fenomeno in tutta la sua problematicità , fino ad arrivare a descrivere l’attuale processo di omologazione reciproca
Photocatalytic CO2 reduction in gas-solid regime in the presence of H2O by using GaP/TiO2 composite as photocatalyst under simulated solar light
GaP/TiO2 composites exhibited a remarkable photocatalytic activity for CO2 reduction in the presence of water vapor producing methane. By decreasing the GaP:TiO2 mass ratio an increase in the photocatalytic activity of the composite was observed for up to a 1:10 mass ratio. The photocatalytic activity of the composite can be attributed to the band structures of the solids as well as to the efficient charge transfer between GaP and TiO2 heterojunction
Genotoxicity of citrus wastewater in prokaryotic and eukaryotic cells and efficiency of heterogeneous photocatalysis by TiO2
The presence of (±)a-pinene, (+)b-pinene, (+)3-carene, and R-(+)limonene terpenes in wastewater of a citrus transformation factory was detected and analyzed, in a previous study, by using Solid Phase Microextraction (SPME) followed by GC analyses. Purpose of that research was to compare the genotoxic responses of mixtures of terpenes with the genotoxicity of the individual compounds, and the biological effects of actual wastewater. Genotoxicity was evaluated in the Salmonella reversion assay (Ames test) and in V79 cells by Comet assay. Ames tests indicated that the four single terpenes did not induce an increase of revertants frequency. On the contrary, the mixtures of terpenes caused, in the presence of metabolic activation, a highly significant increase of the revertants in TA100 strain in comparison to the control. The Comet assay showed a significant increase in DNA damage in V79 cells treated for 1 h with single or mixed terpenes. Moreover, the actual wastewater was found highly genotoxic in bacterial and mammalian cells. Photocatalytic tests completely photodegraded the pollutants present in aqueous wastewater and the initial high genotoxicity of samples of wastewater collected during the photocatalytic run, was completely lose in 3 h of irradiation
Strontium and iron-doped barium cobaltite prepared by solution combustion synthesis: exploring a mixed-fuel approach for tailored intermediate temperature solid oxide fuel cell cathode materials
Ba0.5Sr0.5Co0.8Fe0.2O3–δ (BSCF) powders were prepared by solution combustion synthesis using single and double fuels. The effect of the fuel mixture on the main properties of this well-known solid oxide fuel cell cathode material with high oxygen ion and electronic conduction was investigated in detail. Results showed that the fuel mixture significantly affected the area-specific resistance of the BSCF cathode materials, by controlling the oxygen deficiency and stabilizing the Co2+ oxidation state. It was demonstrated that high fuel-to-metal cations molar ratios and high reducing power of the combustion fuel mixture are mainly responsible for the decreasing of the area-specific resistance of BSCF cathode materials. Moreover, a new metastable monoclinic phase with Ba0.5Sr0.5CO3 composition was discovered in the as-burned BSCF powders, enlarging the existing information on the BSCF phase formation mechanis
Extruded Expanded Polystyrene Sheets Coated by TiO2 as New Photocatalitic Materials for Foodstuffs Packaging
Nanostructured, photoactive anatase TiO2 sol prepared under very mild conditions using titanium tetraisopropoxide as the precursor is used to functionalise extruded expanded polystyrene (XPS) sheets by spray-coating resulting in stable and active materials functionalised by TiO2 nanoparticles. Photocatalytic tests of these sheets performed in a batch reactor in gas–solid system under UV irradiation show their successful activity in degrading probe molecules (2-propanol, trimethylamine and ethene). Raman spectra ensure the deposition of TiO2 as crystalline anatase phase on the polymer surface. The presence of TiO2 with respect to polymer surface can be observed in SEM images coupled to EDAX mapping allowing to monitor the surface morphology and the distribution of TiO2 particles. Finally thermoforming of these sheets in industrial standard equipment leads to useful containers for foodstuffs
Au/CeO2 Photocatalyst for the Selective Oxidation of Aromatic Alcohols in Water under UV, Visible and Solar Irradiation
Au nanoparticles supported on CeO2 have been prepared and investigated as photocatalysts for the photocatalytic selective oxidation of benzyl alcohol and 4-methoxybenzyl alcohol to the correspondent benzaldehydes, in aqueous suspensions and room conditions under UV, visible and
natural solar light irradiation. Au nanoparticles have been supported by impregnation (1 and 3 wt.%) on two types of CeO2 (i.e., a commercial one and a home prepared oxide obtained in the presence of NaOH as precipitation agent). The Au impregnated samples showed strong visible radiation
absorption at 565–570 nm associated to localized surface plasmon resonance (LSPR). The bare CeO2 samples are activated by UV light and resulted virtually inactive under visible irradiation, whereas the presence of Au improved both the conversion of the alcohols and the selectivity of the reaction
towards the aldehyde, giving rise to good results, particularly under visible and natural solar light irradiation. The activity of the materials increased by increasing the Au content
