The power of the gift: a perspective of political aesthetics
2019
According to Aristotle (Polit. 1253a) man is a “political animal” and his aim is to live in the community. Guided by this Aristotelian premise, I would like to dwell on the relevance of a relationship among individuals as the foundation of a civil society and the building of a political space. Following the Aristotelian perspective, the relationship among people acquires a political value in reference to the Greek word polis (city). Consequently, the adjective “political” indicates an idea wider than usually acknowledged and may refer to space, objects, and overall relationships among people. According to the natural model originally advocated by Aristotle, the urban space acquires a politi…
Aesthetic Perspectives on Culture, Politics, and Landscape. Appearances of the “Political”
2022
This book investigates how we are involved in politically informed structures and how they appear to us. Following different approaches in contemporary aesthetics and cultural philosophy, such as everyday aesthetics, atmosphere and aestheticization, the authors explore how embedded powers in politics, education, democracy, and landscape are analyzed through aesthetics.
Artificare lo spazio urbano. Lo sguardo “altro” di Danisinni
2019
Se nella città di Palermo, come in altre città italiane e del mondo, l’incompiuto è segno di un percorso trasformativo che ha subito un arresto, nel rione palermitano di Danisinni l’incompiuto è simbolo di una dimensione esistenziale. Infatti, non solo dal punto di vista topografico, ma anche da quello economico e sociale Danisinni costituisce un mondo chiuso in sé stesso: è un villaggio dentro la città, ma al contempo è un luogo periferico e marginale, tagliato anche dai collegamenti pubblici. Tuttavia negli ultimi anni in questo quartiere sono stati avviati dei processi di riqualificazione urbana che hanno fatto ricorso alle arti da strada (murales, spettacoli teatrali e circensi). Il sag…
Evaluation of quality parameters of strawberry fruits in modified atmosphere packaging during storage
2010
The objective of the present study is to evaluate the effect of modified atmosphere packaging (MAP) during storage on some quality parameters of strawberries. Strawberries (cv. Camarosa) were harvested when mature, forced air cooled and divided into two groups as fruits in MAP and control. After packaging, fruits were stored at 0°C, 90 - 95% RH for 10 days plus 1 day at 20°C and 50 - 55% RH for the evaluation of shelf life. Changes in fruit quality, mass loss, decay, color, firmness, total soluble solids (TSS), acidity, glucose, fructose, saccharose and color were investigated. The mass loss and decay were lower in MAP than observed in the control whereas firmness, TSS, acidity and color di…
A fluorescence retrieval method for the flex sentinel-3 tandem mission
2014
A new fluorescence retrieval method is proposed to support ESA's 8th Earth Explorer Fluorescence EXplorer (FLEX) candidate mission. Most hyperspectral fluorescence retrieval algorithms available in the literature are very sensitive to true reflectance modelization and/or they assume the atmospheric status as known. The proposed algorithm delivers the retrieval of full fluorescence spectrum at canopy level by using only Top Of Atmosphere (TOA) radiances as input. The proposed method starts with (1) the atmospheric correction of TOA radiances, characterizing the state of the atmosphere without assuming any a-priori classification on aerosols models, (2) performing a first estimation of fluore…
Tiempo para hablar y tiempo para callar: uso y función del silencio en un auto religioso de fines del XVI
2013
En este artículo nos proponemos una primera aproximación a un auto religioso inédito de fines del siglo XVI titulado "Auto de la cena a lo divino", tomando como eje articulatorio del mismo la estrategia comunicativa que el anónimo dramaturgo lleva a cabo con la noción de silencio. En la primera parte analizaremos ampliamente el modo en que el autor se sirve de la ausencia de palabras para crear una atmósfera ritual y celebrativa que vincula esta pieza dramática con la liturgia. A continuación subrayaremos algunas fórmulas teatrales inherentes al lenguaje teatral relacionadas con el silencio que se descubren ineficaces en cuanto a su función primordial de generar tensión dramática, pero sí c…
Defect-related visible luminescence of silica nanoparticles
2013
The high photon emissivity in the visible spectral range is one of the most relevant phenomena emerging from the reduction of silica down to nanoscale; hence it is promising for the development of optical nanotechnologies (down converter, probes, display). It is well accepted that the origin of this luminescence is related to the high specific surface (~100 m2/g) that favors the formation of optically active defects at the nanosilica surface. With the aim to clarify the role of specific luminescent defects, here we report a detailed study of spectral and decay features by time-resolved photoluminescence spectra under a visible-UV tunable laser excitation. Our study is carried out on differe…
Search for Gamma-Ray Emission from the Sun during Solar Minimum with the ARGO-YBJ Experiment
2019
The hadronic interaction of cosmic rays with solar atmosphere can produce high energy gamma-rays. The gamma-ray luminosity is correlated both with the flux of primary cosmic rays and the intensity of the solar magnetic field. The gamma-rays below 200 GeV have been observed by Fermi without any evident energy cutoff. The bright gamma-ray flux above 100 GeV has been detected only during solar minimum. The only available data in the TeV range come from the HAWC observations, however, outside the solar minimum. The ARGO-YBJ data set has been used to search for sub-TeV/TeV gamma-rays from the Sun during the solar minimum from 2008 to 2010, the same time period covered by the Fermi data. A suitab…
Continental degassing of helium in an active tectonic setting (northern Italy): the role of seismicity
2020
AbstractIn order to investigate the variability of helium degassing in continental regions, its release from rocks and emission into the atmosphere, here we studied the degassing of volatiles in a seismically active region of northern Italy (MwMAX = 6) at the Nirano-Regnano mud volcanic system. The emitted gases in the study area are CH4–dominated and it is the carrier for helium (He) transfer through the crust. Carbon and He isotopes unequivocally indicate that crustal-derived fluids dominate these systems. An high-resolution 3-dimensional reconstruction of the gas reservoirs feeding the observed gas emissions at the surface permits to estimate the amount of He stored in the natural reserv…
ChemInform Abstract: Synthesis of 4(5)-Phenacyl-imidazoles from Isoxazole Side-Chain Rearrangements.
