Lo Schopenhauer di Giorgio De Chirico
No full textENG The essay provides an in-depth analysis of the intricate relationship between Giorgio De Chirico's artistic oeuvre and the philosophical thought of Schopenhauer and Nietzsche, emphasising the influence of Schopenhauer's philosophy, often overlooked by critics. The author investigates how De Chirico absorbed Schopenhauer's philosophy through Nietzsche, thus formulating a peculiar synthesis of the perspectives of the two German philosophers, which emerges distinctly in his metaphysical art. Furthermore, the essay examines the concept of ‘metaphysics’ as interpreted by De Chirico, understood as a dimension beyond human logic, attainable through an artistic act of ‘clairvoyance’ based on Schopenhauer's doctrine of ideas (Ideenlehre). The analysis also reflects on the artist's extraordinary ability to grasp metaphysical elements within everyday reality, highlighting the link between genius and madness theorised by Schopenhauer. This interconnection between philosophy, metaphysics and art demonstrates how De Chirico found in painting an expressive medium for his original, innovative and profoundly philosophical vision.
ITA Il saggio analizza approfonditamente la complessa relazione tra l'opera di Giorgio De Chirico e il pensiero filosofico di Schopenhauer e Nietzsche, focalizzandosi sull'influenza della filosofia schopenhaueriana, spesso trascurata dalla critica. L'autore esplora come De Chirico recepisca Schopenhauer attraverso Nietzsche, proponendo una sintesi unica tra le visioni dei due filosofi tedeschi, che emergono chiaramente nella sua arte metafisica. Viene approfondito il concetto di "metafisica" intesa da De Chirico come una dimensione oltre la logica umana, accessibile attraverso un atto di "chiaroveggenza" artistica, che si fonda sulla dottrina delle idee di Schopenhauer. L'analisi include una riflessione sulla geniale capacità dell'artista di cogliere gli aspetti metafisici del mondo quotidiano, mettendo in luce il legame tra genio e follia teorizzato da Schopenhauer. Questo rapporto tra filosofia, metafisica e arte rivela come De Chirico abbia trovato nella pittura un mezzo espressivo per la sua visione originale, innovativa e profondamente filosofica
The metaphysical art of Giorgio de Chirico. Migraine or epilepsy?
No full textIt has been suggested that the great Italian painter Giorgio de Chirico (1888-1978), who developed the unique style of 'metaphysical art', suffered from migraine and used some of his morbid manifestations as a source of inspiration for his paintings. Yet, whereas many of the symptoms that de Chirico described are rare in migraine, they are frequently encountered in patients with temporal lobe epilepsy. Here we rediscuss de Chirico's symptoms critically and suggest that, if his symptoms were of neurological origin, they rather relate to temporal lobe epilepsy than migraine.LNCOComment in: Eur Neurol. 2004;51(3):186; author reply 186-7 and Eur Neurol. 2003;50(4):189-9
Primary and secondary organic aerosol origin by combined gas-particle phase source apportionment
No full textSecondary organic aerosol (SOA), a prominent fraction of particulate organic mass (OA), remains poorly constrained. Its formation involves several unknown precursors, formation and evolution pathways and multiple natural and anthropogenic sources. Here a combined gas-particle phase source apportionment is applied to wintertime and summertime data collected in the megacity of Paris in order to investigate SOA origin during both seasons. This was possible by combining the information provided by an aerosol mass spectrometer (AMS) and a proton transfer reaction mass spectrometer (PTR-MS). A better constrained apportionment of primary OA (POA) sources is also achieved using this methodology, making use of gas-phase tracers. These tracers made possible the discrimination between biogenic and continental/anthropogenic sources of SOA. We found that continental SOA was dominant during both seasons (24-50% of total OA), while contributions from photochemistrydriven SOA (9% of total OA) and marine emissions (13% of total OA) were also observed during summertime. A semivolatile nighttime component was also identified (up to 18% of total OA during wintertime). This approach was successfully applied here and implemented in a new source apportionment toolkit. © 2008 Author (s)
Un frammento di Timocle comico
No full textThe author inquires the question about the dramatic nature of Timocle’s Ikarioi Saturoi, a question much discussed by the classical scholarship of the nineteenth
and twentieth century. The new reading of fr. 18 K.-A., handed down from Athenaeus, discloses exact correspondences, concerning language and performance,
with Eupoli’s Demoi and, above all, with Aristofane’s Ploutos, so that it’s possible to lean to the opinion that the work has comic, and not satyrical, nature
Wintertime aerosol chemical composition and source apportionment of the organic fraction in the metropolitan area of Paris
No full textThe effect of a post-industrial megacity on local and regional air quality was assessed via a month-long field measurement campaign in the Paris metropolitan area during winter 2010. Here we present source apportionment results from three aerosol mass spectrometers and two aethalometers deployed at three measurement stations within the Paris region. Submicron aerosol composition is dominated by the organic fraction (30-36%) and nitrate (28-29%), with lower contributions from sulfate (14-16%), ammonium (12-14%) and black carbon (7-13%). Organic source apportionment was performed using positive matrix factorization, resulting in a set of organic factors corresponding both to primary emission sources and secondary production. The dominant primary sources are traffic (11-15% of organic mass), biomass burning (13-15%) and cooking (up to 35% during meal hours). Secondary organic aerosol contributes more than 50% to the total organic mass and includes a highly oxidized factor from indeterminate and/or diverse sources and a less oxidized factor related to wood burning emissions. Black carbon was apportioned to traffic and wood burning sources using a model based on wavelength-dependent light absorption of these two combustion sources. The time series of organic and black carbon factors from related sources were strongly correlated. The similarities in aerosol composition, total mass and temporal variation between the three sites suggest that particulate pollution in Paris is dominated by regional factors, and that the emissions from Paris itself have a relatively low impact on its surroundings. © 2013 Author(s)
Effect of photochemical ageing on the ice nucleation properties of diesel and wood burning particles
No full textA measurement campaign (IMBALANCE) conducted in 2009 was aimed at characterizing the physical and chemical properties of freshly emitted and photochemically aged combustion particles emitted from a log wood burner and diesel vehicles: a EURO3 Opel Astra with a diesel oxidation catalyst (DOC) but no particle filter and a EURO2 Volkswagen Transporter TDI Syncro without emission aftertreatment. Ice nucleation experiments in the deposition and condensation freezing modes were conducted with the Portable Ice Nucleation Chamber (PINC) at three nominal temperatures,-30°C,-35°C and-40°C. Freshly emitted diesel particles showed ice formation only at-40°C in the deposition mode at 137% relative humidity with respect to ice (RHi) and 92% relative humidity with respect to water (RHw), and photochemical ageing did not play a role in modifying their ice nucleation behaviour. Only one diesel experiment where α-pinene was added for the ageing process, showed an ice nucleation enhancement at-35°C. Wood burning particles also act as ice nuclei (IN) at-40°C in the deposition mode at the same conditions as for diesel particles and photochemical ageing also did not alter the ice formation properties of the wood burning particles. Unlike diesel particles, wood burning particles form ice via condensation freezing at-35°C whereas no ice nucleation was observed at-30°C. Photochemical ageing did not affect the ice nucleation ability of the diesel and wood burning particles at the three different temperatures investigated but a broader range of temperatures below-40°C need to be investigated in order to draw an overall conclusion on the effect of photochemical ageing on deposition/condensation ice nucleation across the entire temperature range relevant to cold clouds. © 2013 Author(s)

No full textHydros Phobia è il risultato delle ricerche condotte dall'autore come relatore della tesi di laurea di Michele De Chirico.La tattilità riveste un ruolo fondamentale nella percezione del colore. Nell’ambito della ricerca sulle qualità cromatiche dei prodotti, condotta negli ultimi dieci anni da Vitra in collaborazione con la designer Hella Jongerius, la Tesi riflette sull’aspetto materico del colore, quindi su come il pigmento reagente con il materiale generi un colore-sostanza. Viene così definito un “colore strutturale”, mai indipendente dal materiale con cui reagisce e dal contesto in cui avviene l’osservazione: in ragione di ciò le palette cromatiche diventano nella realtà palette cromatico-materiche. Le riflessioni sull’aspetto strutturale del colore che agisce su una superficie e reagisce a essa hanno condotto al concept di un materiale potenziato sensorialmente attraverso la definizione di un rapporto sinestetico fra l’aspetto tattile e l’aspetto visivo.Hydros Philia is the result of research conducted by the author as a rapporteur for Michele De Chirico's degree thesis. Tactility plays a fundamental role in color perception. As part of research into product colour quality conducted over the last ten years by Vitra in collaboration with designer Hella Joungerius, this thesis reflects on the material aspect of colour and on how the reagent pigment generates a color-substance together with the material. This is thus defined as a "structural colour" that is constantly part of the material with which it reacts and the context in which observation takes place - as a result the range of colors become effectively a range of colour-materials. These considerations on the structural aspect of colour acting on a surfaces and reacting to it led to the concept of sensory-enfaced material through the definition of a synaesthetic relationship between the tactile and the visual aspect
