Cambiamento e continuità: i manoscritti del fondo musicale del duomo di Enna
2018
Dal Cinquecento fino agli inizi del Novecento la vita musicale a Enna – cittadina al centro della Sicilia – fu caratterizzata da particolare vivacità. Ciò si dovette soprattutto all'attività della sua più importante istituzione religiosa, la cappella musicale del Duomo, che impiegava un numero stabile di musicisti, per la maggior parte siciliani, ma anche stranieri. Fu soprattutto nel Settecento che molti di loro giunsero a Enna da Napoli, il più prestigioso centro musicale dell'epoca. Vi troviamo virtuosi cantori e strumentisti, ma anche compositori come Luigi Platone o Giuseppe Coppola, entrambi giunti in Sicilia alla fine del secolo e divenuti maestri dell'istituzione. La prolifica attiv…
Graduate of Riga Polytechnic Institute, Engineer and Athlete Mārtiņš Stabiņš
2020
The aim of the article is to reveal the performance of Mārtiņš Stabiņš, a graduate of the Faculty of Automation and Computer Technology (1972; FACT) of Riga Polytechnic Institute (RPI), in the profession of engineer and high achievements in sports, becoming a Latvian champion in athletics several times, to reveal his daily life during his study years in the 1960s–1970s. Despite the fact that M. Stabiņš’ sports achievements have already described, this article summarizes his successes as well as reveals hitherto little-known and unpublished documents about his family, daily life, developments and interests. This is the first major research on the life of an engineer and athlete during seven …
Typical Aspects of the Microwave Noise Performance of HEMTs at Decreasing Temperatures
1996
In analog signal processing at microwave frequencies the noise performance of active devices is of fundamental importance for the accurate design of low-noise amplifiers. To this aim, the determination of the four noise parameters F O , Γ O (complex variable) and Rn has to be accomplished together with the usual scattering parameter measurements vs. frequency. In addition, the dependence of the device performance vs. temperature is of interest for circuit applications characterized by harsh environmental conditions. In this work the noise behavior of high electron mobility transistors has been investigated by means of measurements and modeling in the 2-18 GHz frequency range and as a functi…
Fermi-Dirac correlations in Lambda pairs in hadronic Z decays
2000
Two-particle correlations of Lambda Lambda and pairs have been studied in multihadronic Z decays recorded with the ALEPH detector at LEP in the years from 1992 to 1995. The correlations were measured as a function of the four-momentum difference Q of the pair. A depletion of events is observed in the region Q 2 GeV the fraction of pairs with spin one is consistent with the value of 0.75 expected for a statistical spin mixture, whilst for Q pairs, where no Fermi-Dirac correlations are expected, the spin one fraction is measured to be consistent with 0.75 over the entire analysed Q range.

The taint of torture and the brazilian legal system
2019
In Brazil, the practice of torture intertwines deeply with its own history. The literature on the subject has had a greater intensification on its registers during the Dictatorial Regime (1964 to 1985). In spite of the Brazilian Constitution of 1988, Brazil only makes efforts to investigate the crimes of torture of this period to comply with the provisions of the United Nations in 2011. Within this scenario, the NationalTruth Commission (Law 12.528, of November 2011) was created with the purpose of clarifying the facts and circumstances of cases concerning human rights violations, as well as the Law on Access to Information (Law 12.527 of November 2011), which have regulated the constitutio…
Un'identità femminile
2018
Il testo illustra la figura di Anna Maria Fundarò, architetto e docente universitaria, fondatrice negli anni '70 della scuola di design dell'Università di Palermo; è strutturato con una breve profilo di A.M. Fundarò e una successiva conversazione a tre voci tra Mario Damiani Almeyda, custode dell' archivio Damiani Almeyda Fundarò, Paola Barbera, storica dell'architettura, Viviana Trapani che oggi insegna Design all'Università di Palermo, diretta dallo studio OMA, curatore della Biennale Nomade d'Arte Contemporanea Manifesta, svoltasi a Palermo nel 2018. Il contributo di V.M. Trapani è centrale nel delineare la rilevanza e l'originalità scientifica e didattica della figura di Anna Maria Fund…
L'archivio del cantiere navale di Palermo
2015
Il cantiere navale di Palermo nasce all’interno di un disegno organico che ha come protagonista l’impero industria- le della più importante famiglia imprenditoriale del XIX secolo in Sicilia, i Florio. L’impresa nasce con lo scopo di garantire alla produzione isolana un ruolo nel disegno politico e nei piani economici del nuovo Regno d’Italia. In questa prima fase, il cantiere navale è caratterizzato da valenze fortemente identitarie legate al territorio urbano e alle espressioni culturali della borghesia di ne ‘800 a Palermo. Il passaggio dello stabilimento navale ad uno dei più potenti gruppi industriali italiani, facente capo ad una dinastia familiare del settentrione d’Italia, determina…
Type II narrow double barrier quantum well structures : Γ-X coupling and interface effects
1993
Photoluminescence (PL), PL excitation and time resolved PL experiments have been performed on Al0.42Ga0.58As/AlAs/GaAs symmetric double barrier quantum wells (DBQW) with only one or two AlAs monolayers constituting the intermediate barriers. In agreement with the envelope function predictions we show that such DBQW's undergo a type I - type II transition when the GaAs thickness is reduced below 7 and 5 monolayers for 2 and 1 AlAs molecular planes respectively. In type II configuration the PL decay time is found to be strongly dependent on the energy difference between AlAs Xz - and GaAs Γ - electron confined states and the coupling parameter of the Γ and Xz valleys can be deduced (4.2 meV o…
Electrooptic beam deflection with latex
1988
The use of latex in electrooptic devices is proposed. The static non linearity coefficient is shown to be approximatively 200 times the optical one. The theory of a beam deflector is developed and an explicit expression is given for the deflection angle versus the physical parameters of the sample Utilisation de suspensions aqueuses de latex dans un dispositif electro-optique. On montre que le coefficient statique de non-linearite devrait etre 200 fois plus eleve que le coefficient optique. Application a un deflecteur optique
