The history of the Romano famili and "Angelo, tyran de Padoue" by Victor Hugo.
No full textreservedVictor Hugo, nel dramma Angelo, tyran de Padue, ricama tre diverse epoche storiche: i primi decenni dell’Ottocento, a lui contemporanei; la metà del Cinquecento, prescelta per lo svolgimento dell’azione drammatica; il tardo Medioevo evinto dai personaggi principali che compongono il racconto. Tuttavia, l’interesse storico e prettamente romantico verso il periodo medievale assume in quest’opera una rilevanza primaria. Tra le tante casate del nord Italia nominate dall’autore nell’opera, una su tutte sembra essere davvero simbolica. Particolarmente interessante è stato comprendere come la storia della famiglia da Romano costituisca il fulcro della costruzione drammaturgica. Ezzelino III e Cunizza da Romano sono elevati a emblema della poetica romantica e divengono funzionali al messaggio politico e sociale dell’autore.Victor Hugo, in his play Angelo, tyran de Padue, embroiders three different historical epochs: the first decades of the 19th century, contemporary with him; the middle of the 16th century, chosen for the unfolding of the dramatic action; and the late Middle Ages evoked by the main characters in the story. However, the historical and purely romantic interest in the medieval period takes on primary importance in this work. Of the many northern Italian lineages named by the author in the work, one in particular seems to be truly symbolic. It was particularly interesting to understand how the history of the da Romano family forms the core of the dramaturgical construction. Ezzelino III and Cunizza da Romano are elevated to emblems of romantic poetics and become functional to the author's political and social message
Phantom scalar-tensor models and cosmological tensions
Get PDFWe study three different extended scalar-tensor theories of gravity by also
allowing a negative sign for the kinetic term for the scalar field in the
Jordan frame. Our scope is to understand how the observational constraints for
these models cope with the volume of the parameter space in which the theory is
healthy. Models with a negative kinetic term lead to decreasing effective
gravitational constant with redshift and behave as an effective relativistic
component with a negative energy density as opposite to their corresponding
version with a standard kinetic term. As a consequence, we find that the
extended branch with a negative sign for the kinetic term correspond in general
to lower and compared to CDM. We find that in all the
cases with a negative sign for the kinetic term studied here, cosmological
observations constrain these models around GR and prefer a volume of the
parameter space in which the theory is not healthy since the scalar field
behave as a ghost also in the related Einstein frame. We show that also in the
phantom branch early modify gravity with a quartic coupling can substantially
reduce the tension fitting the combination of cosmic microwave background
data from Planck, baryon acoustic oscillations from BOSS and eBOSS, and
Supernovae from the Pantheon sample with calibration information by SH0ES.Comment: 33 pages, 11 figures, 6 table

Oltre i confini della razionalità
No full text- Il contributo di Angelo Volpe prende in esame fondamentalmen-te due oggetti: primo, la potenzialità indiscussa nella sociologia contemporanea degli approcci individualistici e razionali e, secondo, la necessità di trascendere la gabbia stessa della razionalità e di andare oltre. Ciò che l’autore auspica è la realizzazione di un “modello a spettro intero” per l’analisi dei fatti sociali, un modello che possa espandere il raggio d’azione della comprensione sociologica al di là di ciò che possiamo vedere e misurare razionalmente.
- The contribution of Angelo Volpe essentially examines two objects: first, the unquestioned potentiality in contemporary sociology of individualistic and rational approaches, and, second, the need to transcend the very cage of rationality and go further. What the author hopes is the realization of a "full-spectrum model" for the analysis of social events, a model that can expand the scope of sociological understanding beyond what we can see and measure rationally

La fabbrica illuminata
No full textLa fabbrica illuminata, for voice and four-track magnetic tape, was composed by Luigi Nono in 1964. The music on tape, recorded at the Studio di Fonologia Musicale of the RAI in Milan, was the result of the complex elaboration of audio materials from different sources: parts performed by the RAI choir of Milan, “thematic” improvisations sung by the mezzo-soprano Carla Henius, voices and noises from the Italsider plant in Genoa-Cornigliano, and synthesized sounds.
Original audio sources
Three versions by the author were identified in the RAI archives in Milan:
Milan RAI Q6, 1964, analogue magnetic tape, 1 inch, 38 cm/s, quadraphonic, created by the author for performance with live voice;
Milan RAI Q7, 1965, analogue magnetic tape, 1 inch, 38 cm/s, quadraphonic. With the soloist voice recorded3 ;
Milan RAI E28, 196[5], analogue magnetic tape, 1⁄4 inch, 38 cm/s, monophonic. With the soloist voice recorded;
The copy deposited for copyright is conserved in the Ricordi Archive, Milan:
Milan Ricordi E214, 196[7], analogue magnetic tape, 1 inch, 38 cm/s, quadraphonic.
The tapes are still in good condition and include a set of metadata pertinent to the content of the recordings. The preservative re-recording of the analogue document in digital format was carried out in the Audio laboratory of the RAI in Milan, together with the MIRAGE Laboratory.
This restoration is tied to the basic document CLN 0002 in the Archive of Casa Ricordi in Milan, a digital conservative copy of the magnetic tape Q6 of the Archive of the Studio di Fonologia at the RAI in Milan.
The restoration of the sound tracks of the work has been completed at the Audio Laboratories of the University of Udine (Gorizia campus)under the expert supervision of Angelo Orcalli and edited by Angelo Orcalli. This restored version was based on the original documents and is accompanied with a technical report
Cosmological effects of the Galileon term in Scalar-Tensor Theories
Get PDFWe study the cosmological effects of a Galileon term in scalar-tensor
theories of gravity. The subset of scalar-tensor theories considered are
characterized by a non-minimal coupling , a kinetic term with
arbitrary sign with , a potential
, and a Galileon term . In addition to the modified dynamics, the Galileon term provides a
screening mechanism to potentially reconcile the models with General Relativity
predictions inside a Vainshtein radius. Thanks to the Galileon term, the
stability conditions, namely ghost and Laplacian instabilities, in the branch
with a negative kinetic term () are fulfilled for a large volume of the
parameter space. Solving numerically the background evolution and linear
perturbations, we derive the constraints on the cosmological parameters in
presence of a Galileon term for different combination of the cosmic microwave
background (CMB) data from Planck, baryon acoustic oscillations (BAO)
measurements from BOSS, and supernovae from the Pantheon compilation. We find
that the Galileon term alters the dynamics of all the studied cases. For a
standard kinetic term (), we find that Planck data and a compilation of
BAO data constrain the Galileon term to small values that allow screening very
inefficiently. For a negative kinetic term (), a Galileon term and a
non-zero potential lead to an efficient screening in a physically viable regime
of the theory, with a value for the Hubble constant today which alleviates the
tension between its CMB and local determinations. For a vanishing potential,
the case with and the Galileon term driving the late acceleration of the
Universe is ruled out by Planck data.Comment: 23 pages, 15 figures, 4 table

Role of blue dye for sentinel lymph node detection in early endometrial cancer
No full textBackground: Sentinel Lymphonode analysis has become a barely new and innovative way to treat early stages of endometrial cancer (Ballester et al., Lancet Oncol 469â476, 2011; Buda et al., Ann Surg Oncol 2975-81, 2016). Indocyanine green cervical injection is considered gold standard for mapping nodesâ drainage. Blue dye is used as a valid alternative in many centers, due to the lower cost of execution. The objective of this video is to prove that methylene blue dyeâs cervical injection is a valid and âlow-costâ method to obtain mapping of lymphatic drainage in patient with early endometrial cancer. Methods: Fifty-four-year old women, with a recent diagnosis of endometrial cancer IA G2, we performed a radical Hysterectomy type A. We diluted in equal proportions the blue dye and saline and injected 1Â cl in depth and 1Â cl on the surface of the cervix, at 3 oâclock and 9 oâclock. After 20Â min, it was shown with precision the lymphatic drainage until the first lymph node station from both sides. Results: One external iliac lymph node and one obturator were resected on the left side and one external iliac on the right side. On histological analysis, none of the lymph nodes had any location of metastasis, neither micro-metastasis. Myometrial infiltration was 8/19Â mm. Conclusions: Blue dye cervical injection is a âlow-costâ, safe, and satisfactory procedure to point out Sentinel Lymph Node of uterus drainage. Other tracers, such as indocyanine green, are widely used in gynecological oncology, but with a higher cost of the product and the needing of a dedicated optical filter to be shown on human view
