The language of Poesie a Casarsa. The "invented" friulian of Pier Paolo Pasolini
No full textopenIl presente elaborato analizza il “timp furlan” di Pier Paolo Pasolini, con particolare attenzione rivolta alla pubblicazione di Poesie a Casarsa (1942) e alla lingua utilizzata dall’autore per comporre le poesie della raccolta. La ricerca prende avvio con un rapido excursus sugli sviluppi della poesia dialettale tra XIX e XX secolo, approfondendo l’influenza esercitata da Pascoli sui poeti dialettali di primo Novecento e il tentativo di conferire dignità linguistica e letteraria ai dialetti. Il cuore della trattazione concentra l’interesse sull’esperienza trascorsa in Friuli di Pasolini e sulla lingua friulana intesa dal poeta come lingua per la poesia, l’unica capace di toccare le corde più profonde dell’animo del poeta e di portare alla memoria la purezza degli anni trascorsi in Friuli. Lo studio prosegue approfondendo lo sviluppo sia strutturale che linguistico di Poesie a Casarsa, dal progetto de I confini in italiano, alla dialetizzazione dei componimenti, sino alla pubblicazione della raccolta in dialetto casarsese. La veste linguistica della prima raccolta friulana non dimostra una totale fedeltà al dialetto casarsese poiché accoglie elementi derivanti da friulani differenti. Viene proposta quindi una analisi linguistica del dialetto utilizzato da Pasolini, mostrando le variazioni che allontanano la lingua della raccolta dal reale casarsese e proponendo successivamente la corretta terminologia.This paper analyses Pier Paolo Pasolini's "timp furlan", with particular attention paid to the pubblication of Poesie a Casarsa (1942) and the language used by the author to compose the poems in the collection. This research begins with a quick excursus on the development of dialect poetry between the 19th and 20th centuries, examining in depth the influence exercised by Pascoli on early 20th century dialect poets and the attempt to confer linguitic and literary dignity on dialects. The heart of the treatment focuses on Pasolini's experience in Friuli and on the Friulian language, understood by the poet as a language of poetry, the only one capable of touching che deepest chords of the poet's soul and bringing to memory the purity of years spent in Friuli. The study continues by delving into both the structural and linguistic development of Poesie a Casarsa, from the project of I confini in italian, to the dialetisation of the poems, up to the collection in Casarsa dialect. The linguistic guise of the first friulian collection does not demostrare total fidelity to the dialect of Casarsa, as it incorporates elements derivig from different friulian dialects. Therefore, a linguistic analysis of the dialect used by Pasolini in proposed, showing the variations that distance the language of the collection from the real Casarsese and then proposing the correct terminology
Monochromatic single photon events at the muon collider
No full textThe cross section for lepton pair annihilation into a photon and a dark photon or an axionlike particle is constant for large center-of-mass energies because some of the portal operators coupling the Standard Model and dark sector are proportional to the energy. Feebly coupled though they are, these portal operators will be enhanced by the large center-of-mass energy made available by a muon collider and thus provide the ideal example of possible physics beyond the Standard Model to be studied with such a machine. We discuss the characteristic signature of the presence of these operators: monochromatic single photon events for the two benchmarks of having center-of-mass energies of 3 and 10 TeV and integrated luminosity of, respectively, 1 and 10 ab-1. We find that an effective scale of the portal operator as large as Λ=112 TeV for an axionlike particle and Λ=141 TeV for a dark photon can be separated from the background with a confidence level of 95% in the first benchmark; these interaction scales can be raised to Λ=375 and 459 TeV in the case of the second benchmark. The signal for the pseudoscalar particle can be distinguished from that of the spin-1 with about 500 events. The response of the detector to high-energy photons is examined.The cross section for lepton pair annihilation into a photon and a dark photon or an axion-like particle is constant for large center-of-mass energies because some of the portal operators coupling Standard Model and dark sector are proportional to the energy.

Characterization of the velocity and heat transfer fields in an internal cooling channel with high blockage ratio
No full textThe present experimental study is dealing with a detailed aero/thermal investigation of the turbulent flow inside a rib-roughened turbine blade cooling channel by means of Particle Image Velocimetry (PIV) and Liquid Crystal Thermometry (LCT). The main objectives of the paper are to provide detailed information about the behaviour of such a complicated flow, useful for its understanding, and to create a wide and reliable data base for numerical code validation. The measurements are carried out at engine representative Reynolds number within a scaled up model of a stationary straight cooling channel, with turbulent promoters (or ribs) installed on one wall. The ribs have an angle of attack of 90 deg with respect to the “mean” flow direction; their blockage ratio is equal to 30%. Detailed wall heat transfer distributions are presented. The main time-averaged flow features are identified and quantified; a number of rms characteristics are put in evidence and compared to the heat transfer distributions
Aero-acoustic in a tangential blower: validation of the CFD flow distribution using advanced PIV techniques
No full textNoise reduction is of increasing importance in the community.
Consequently, the development of aero-acoustics is gaining special focus
within industry. Computational Aero-Acoustics (CAA), the coupling of
Computational Fluid Dynamics (CFD) and Computational Acoustics (CA), is
being used in the design and assessment of a range of products from
HVAC ducts to domestic appliances.
The process for carrying out an Aero-Acoustic simulation begins with
the solution of the transient flow dynamics in order to compute accurately
the pressure fluctuations at a number of points in the computational
domain. These fluctuations are passed to the acoustic code to propagate
the acoustic waves through the system and determine its acoustic
signature. To minimize errors in the acoustic propagation analysis it is thus
essential that accurate predictions of the noise sources be obtained.
This paper concentrates on the CFD part of the aero-acoustic
simulation. The case considered has been taken from the European
project DESTINY:3 and comprises a tangential blower located inside a
complex duct system. Air is drawn into the fan through two inlets and exits
through a single duct. The computational methodology and flow field
predictions are presented and compared to experimental PIV data. The
numerical predictions were found to be in good agreement with the
experimental data, reproducing the asymmetries in the flow field
