Clara Maffei al cospetto di Verdi. Tra storia e finzione
No full textIl saggio ricostruisce la vita e la figura di Clara Maffei attraverso le pagine dei suoi contemporanei e le rielaborazioni letterarie di Otto e Novecento. Le lacune documentarie e la loro frammentarietà suggeriscono di prendere in considerazione un corpus eterogeneo di testi, che comprende epistolari, biografie, ma anche narrazioni letterarie, cinematografiche e televisive. In queste opere Clara Maffei è presentata come un personaggio secondario che, nondimeno, è essenziale per delineare gli ambienti intellettuali e la società del suo tempo. Il ritratti della celebre salonnière intervengono spesso in biografie di importanti esponenti della cultura ottocentesca, quali Alessandro Manzoni, Carlo Tenca e Giuseppe Verdi. E' in particolare la sua lunga amicizia col grande compositore italiano a costituire l'ambito di maggior interesse, grazie al cospicuo numero di lettere intercorse tra la contessa e Verdi dal 1845 al 1886. Nella seconda parte del saggio l'autore ricostruisce le tappe della loro profonda e duratura amicizia.The essay aims at drawing a portrait of Countess Clara Maffei through the pages of her contemporaries and the fictional reconstructions of her life and personality. The lack of documents at our disposal and their fragmentary nature suggest taking into account a diverse corpus of texts, including novels, movies and teleplays dating from mid-Nineteenth century to present time. In these works Clara Maffei is mainly seen as a minor character who is nevertheless essential for the delineation of the intellectual society of her time. Maffei’s portraits are often to be found in biographies of important personalities such as Alessandro Manzoni, Carlo Tenca and Giuseppe Verdi. Her lifelong friendship with Verdi is of high relevance, thanks to the large number of letters written by and to the Italian composer from 1845 to 1886. Thus, in the second part of this essay the author reconstructs the main events regarding the profound and enduring relationship between Verdi and the famous salonnière

Carlo Tenca, la contessa Maffei, il rinnovamento della letteratura
No full textThe essay follows Carlo Tenca’s intellectual and artistic journey in the light of his relationship with the Countess Maffei and the cultural direction of his important literary salon. Based on his conspicuous epistolary, on the theoretical writings and on various narrative works of the Milanese author, the essay shows how the bond with Clarina, from the second half of the Forties to the unification of Italy, favored his departure from Mazzinian radicalism and the adhesion to the Cavourian and Liberal moderate program expressed by the magazine "Il Crepuscolo"; this political evolution coincided with an artistic turning point for Tenca, who, while not denying Manzoni's authority, sought a more popular literature and, above all, the overcoming of the "historical" tale in a "civil" and "social" direction, tied to contemporary reality
The extinction and distance of Maffei 1
No full textWe have obtained low- and high-resolution
spectra of the core of the highly reddened
elliptical galaxy Maffei 1. From these data, we
have obtained the first measurement of the
Mg2 index and have measured the
velocity dispersion and radial velocity with
improved accuracy. To evaluate the extinction, a
correlation between the Mg2 index and
effective V-I color has been established for
elliptical galaxies. Using a new method for
correcting for effective wavelength shifts, the
V-I color excess reveals that the optical depth
of Galactic dust at 1 mu;m is 1.69+/-0.07.
Thus, AV=4.67+/-0.19 mag, which is
lower by 0.4 mag than previously thought. To
establish the distance, the fundamental plane for
elliptical galaxies has been constructed in I.
The velocity dispersion of Maffei 1, measured to
be 186.8+/-7.4 km s-1, in combination
with modern wide-field photometry in I, leads to
a distance of 2.92+/-0.37 Mpc. The
Dn- sigma; relation, which is
independently calibrated, gives 3.08+/-0.85 and
3.23+/-0.67 Mpc from photometry in B and K',
respectively. The weighted mean of the three
estimates is 3.01+/-0.30 Mpc, which is lower
than distances judged with reference to M32 and
the bulge of M31 from the brightest stars seen
at K'. Since the luminosity of asymptotic giant
branch stars at K' is strongly dependent on age,
the lower distance suggests that the last epoch
of star formation in Maffei 1 occurred farther
in the past than in these other systems. The
distance and luminosity make Maffei 1 the
nearest giant elliptical galaxy. In the absence
of extinction, the galaxy would be among the
brightest in the sky and would have an apparent
size 2/3 that of the full Moon. The radial
velocity of Maffei 1 is +66.4+/-5.0 km
s-1, significantly higher than the
accepted value of -10 km s-1. The
Hubble distance corresponding to the mean
velocity of Maffei 1, Maffei 2, and IC 342 is
3.5 Mpc. Thus, it is unlikely that Maffei 1 has
had any influence on Local Group dynamics

Dual-phase steel rebars for high-ductile r.c. structures, Part 1: Microstructural and mechanical characterization of steel rebars
No full textThe considerable influence of steel's mechanical behaviour on the dissipative capacity of r.c. structures has led to increasing interest in optimizing the mechanical properties of the reinforcing bars used for seismic applications.
The work presented herein is part of a broad-ranging study on the potential utilization of highly innovative types of steel for reinforced concrete earthquake-resistant structures. In particular, we present the main results obtained in experimental trials on a low-C, Mn-Si steel in the form of concrete reinforcing bars subjected to intercritical tempering treatment in a temperature range between 740 and 820 degrees C to obtain various dual-phase ferrite-martensite structures. The samples were characterized via mechanical tests and metallographic analyses in order to correlate the bars' characteristics with the microstructure of the steel itself.
Experimental characterization of this steel has allowed for the development of a mathematical model to enable the evaluation of the ductility performance of concrete structural elements reinforced with dual-phase steel bars
