OPERA resistive plate chambers underground test results
No full textThe OPERA experiment [1] will study nu(mu)->nu(tau) oscillations through tau appearance on the 732 Km long CERN to Gran Sasso baseline. The magnet yokes of the two muon spectrometers are instrumented with 44 layers of high resistivity bakelite Resistive Plate Chambers (RPCs) operated in streamer mode. Each layer covers about 70 m(2). Four RPC planes were instrumented and the first tests were performed confirming a good behaviour of the installed RPCs in terms of intrinsic noise and operating currents. The measured noise maps agree with those obtained in the extensive quality tests performed at surface. Counting rates are below 20 Hz/m(2). Single and multiple cosmic muon tracks were also reconstructed. The estimated efficiency is close to the geometrical limit and the very first measurements of the absolute and differential muon flux are in agreement with expectations
La mauresque sur scène et les contacts musico-teatraux entre l'Italie et la ville de Dubrovnik au XVIe siècle
No full textThe moresca, and the related forms of weapon dance, either spread in the Mediterranean basin or in several countries of Central and Southern Europe, was a kind of 16-century choreography. Born as a battle between Saracens and Christian knights, this dance inspired different kinds of mimic spectacle that served as a part of comedies and pastoral plays.
The article analyses the relationship between the moresca intermingled in the pastorals of Dubrovnik and Siena, both marked by a strong presence of dances, songs and choruses to increase the fantastic and sentimental emphasis of the performances.
Both Dubrovnik’s and Italian’s plays were characterized by shepherds, nymphs, and rustic men (the Croatian vlasi, i.e., Walachians or Morlacks), as well as fantastic and comic elements. Like in Sienese dramaturgy, the music in Croatian pastorals supports a narrative function. It serves as a guide through the development of the plot, namely in some pieces by Nikola Naljeskovic and Marin Drzic. At salient points, they insert choruses or mimic scenes in the vein of Sienese moresca. In what is concerned the instruments played to accompany pantomimes or songs, only rarely there are quotations in courtly form. Actually, the terms taken from Slavic folklore prevail, even though the music on stage was played by the consort
The OPERA cosmic ray test facility at the Gran Sasso
No full textThe OPERA experiment foresees the use of about 3000m(2) of RPCs, that will be tested before the installation in a dedicated cosmic ray test facility. The test facility is composed of 2 triggering walls selecting horizontal cosmic rays muons. Each wall houses 64 glass RPCs equipped with 128 horizontal Flat Cable Strips. The z-coordinate is measured with a standard digital chain, while the x-coordinate is obtained by measuring the propagation time of the signals along the strips. In this paper the performance of the trigger walls and the first results of the RPC debug are presented
Socratenon and its application to the learning of Italian language
No full textSocratenon is a Web engine tuned to advanced Web education using the state-of-the-art Internet development technologies and tools. It enables interactive and creative learning/teaching management in four different domains (provider, administrator, teacher, and student). It also includes an interface to an artificial intelligence based tool for off-line improvement or learning curricula (ABITS or Aristotelon). One of the first applications of Socratenon was to help the learning of Italian language for Serbian students (the product was developed through a cooperation between universities in Salerno and Belgrade). This paper presents the basic elements of the Socratenon application and implementation philosophy, and discusses its possibilities in the general language- learning environment. It describes three different experiments and explains the lessons learned. The stress is on the statistical analysis of success of those who used our Web-based product and those who relied on the classical approaches
