La stupidità dei sensi. Sulla filosofia dell’arte di Arthur C. Danto
2008
Il presente saggio è dedicato all''analisi della teoria essenzialista dell''arte di A. Danto, sia relativamente alla ricostruzione storica su cui è fondata, sia soprattutto alle assunzioni sui processi cognitivi della produzione e della fruizione. Facendo ricorso a evidenze psicologiche e neuroscientifiche, si dimostra che la teoria della percezione utilizzata (derivata da J. Fodor e dai neohelmoltziani) non è adeguata a spiegare le capacità di produzione e comprensione del significato visivo, e entra in conflitto persino con le caratteristiche attribuite all''arte dallo stesso Danto. Si evidenziano inoltre alcune conseguenze controintuitive della teoria, quale, ad esempio, “l’invisibilità …
Detection potential of the KM3NeT detector for high-energy neutrinos from the Fermi bubbles
2013
A recent analysis of the Fermi Large Area Telescope data provided evidence for a high-intensity emission of high-energy gamma rays with a E-2 spectrum from two large areas, spanning 50 above and below the Galactic centre (the "Fermi bubbles"). A hadronic mechanism was proposed for this gamma-ray emission making the Fermi bubbles promising source candidates of high-energy neutrino emission. In this work Monte Carlo simulations regarding the detectability of high-energy neutrinos from the Fermi bubbles with the future multi-km(3) neutrino telescope KM3NeT in the Mediterranean Sea are presented. Under the hypothesis that the gamma-ray emission is completely due to hadronic processes, the resul…
Expansion cone for the 3-inch PMTs of the KM3NeT optical modules
2013
[EN] Detection of high-energy neutrinos from distant astrophysical sources will open a new window on the Universe. The detection principle exploits the measurement of Cherenkov light emitted by charged particles resulting from neutrino interactions in the matter containing the telescope. A novel multi-PMT digital optical module (DOM) was developed to contain 31 3-inch photomultiplier tubes (PMTs). In order to maximize the detector sensitivity, each PMT will be surrounded by an expansion cone which collects photons that would otherwise miss the photocathode. Results for various angles of incidence with respect to the PMT surface indicate an increase in collection efficiency by 30% on average…
Effects of muscular exercise on erythrocyte adenosine triphosphate concentration in patients with insulin-dependent diabetes mellitus.
1987
Type I diabetes mellitus represents a metabolic disorder in which intracellular glycolytic pathway is inhibited by insulin deficiency, with the subsequent decreased availability of energetic substrates such as ATP. Some aspects of the energetic metabolism in response to an intensive demand (muscular exercise) were investigated, in a group of 10 ketotic diabetic patients, by measuring erythrocyte adenosine triphosphate (ATP) and blood glucose, free fatty acids (FFA) and lactate levels. In the diabetic subjects, in comparison with normal subjects, the decreased levels of erythrocyte ATP at rest did not increase after exercise, while the increased levels of FFA at rest did not diminish after e…
