L’altro sapere. Bello, Arte, Immagine in Leon Battista Alberti
2000
The great attention that, during the past few years, has been paid to Leon Battista Alberti has led to the creation of research centers and to the organization of exhibitions and conferences dedicated to him, but it has yet to result, especially in Italy, in a new approach to his aesthetic theories. This represents a serious scholarly gap, because Alberti was an important figure in the history of aesthetics, both for the role he played in the aesthetic and literary debates of the 15th century, as well as for the impact that his thought had on theory and art in subsequent centuries. The present volume constitutes an important tool to fill such gap. The volume centers on three key concepts: b…

2020
Luce da Luce φῶς ἐκ φωτός – Luce su Luce (Nūr ‘alà Nūr) è un progetto che mira a individuare elementi che possano permettere la comparazione tra cultura, tradizione, ritualità ed aspetti religiosi della Cristianità ortodossa e bizantina e la dimensione più mistica e interiore dell’Islam. Durante le giornate studiosi, artisti e teologi si sono confrontati sul tema i cui contributi sono raccolti nel volume di atti. Luce da Luce φῶς ἐκ φωτός - Light on Light (Nūr 'alà Nūr) is a project that aims to identify elements that can allow the comparison between culture, tradition, rituality and religious aspects of Orthodox and Byzantine Christianity and the more mystical and interior dimension of Isl…
Precision Measurement of the Mass and Lifetime of the Ξ[0 over b] Baryon
2014
Using a proton-proton collision data sample corresponding to an integrated luminosity of 3 fb$^{-1}$ collected by LHCb at center-of-mass energies of 7 and 8 TeV, about 3800 $\Xi_b^0\to\Xi_c^+\pi^-$, $\Xi_c^+\to pK^-\pi^+$ signal decays are reconstructed. From this sample, the first measurement of the $\Xi_b^0$ baryon lifetime is made, relative to that of the $\Lambda_b^0$ baryon. The mass differences $M(\Xi_b^0)-M(\Lambda_b^0)$ and $M(\Xi_c^+)-M(\Lambda_c^+)$ are also measured with precision more than four times better than the current world averages. The resulting values are $\frac{\tau_{\Xi_b^0}}{\tau_{\Lambda_b^0}} = 1.006\pm0.018\pm0.010$, $M(\Xi_b^0) - M(\Lambda_b^0) = 172.44\pm0.39\pm…
Search for exclusive decays of the Lambda_b baryon and measurement of its mass
1996
A search for fully reconstructed \lb beauty baryons is performed using about 3 million Z decays collected with the DELPHI detector at LEP. The analysis relies on the combined use of the accurate tracking and of the hadron identification capabilities of DELPHI. A total of four events has been found, three in the \lc\ppm channel and one in the \lc\a1m channel over a small background. The \lb beauty baryon mass is measured to be (~ 5668 \pm 16~ ({\rm stat.}) \pm 8~({\rm syst.})~)~ \mv.
Search for exclusive charmless b meson decays with the Delphi detector at Lep
1995
Charmless hadronic decays of beauty mesons have been searched for using the data collected with the DELPHI detector at the LEP collider. Several two, three and four-body decay modes have been investigated. Particle identification was used to distinguish the final states with protons, kaons and pions. Three candidate events selected in two-body decay modes are interpreted as evidence for charmless B decays. No excess has been found in higher multiplicity modes and improved upper limits for some of the branching ratios are given. © 1995.
Agritourism, between legislation and marketing: A leading sector for local development the case of the province of Palermo
2018
This work stems from a desire to understand the dynamics of a sector that is of particular interest for the economy and regional development of Sicily. Due to its geographical position, rich history, and natural beauty, Sicily is a year-round attraction for large numbers of tourists from all over the world. In this respect, it is vital to invest in the local area, to try to maintain and increase the potential that the territory itself can offer. With this work, we consider the agritourism sector to specifically assess its potential interest for business people and consumers, both actual and potential. Indeed, if on one side modern tourism was born from a desire to visit faraway places, it i…
Measurement of the mass and lifetime of the Ω(−)(b) baryon
2016
A proton-proton collision data sample, corresponding to an integrated luminosity of 3 fb$^{-1}$ collected by LHCb at $\sqrt{s}=7$ and 8 TeV, is used to reconstruct $63\pm9$ $\Omega_b^-\to\Omega_c^0\pi^-$, $\Omega_c^0\to pK^-K^-\pi^+$ decays. Using the $\Xi_b^-\to\Xi_c^0\pi^-$, $\Xi_c^0\to pK^-K^-\pi^+$ decay mode for calibration, the lifetime ratio and absolute lifetime of the $\Omega_b^-$ baryon are measured to be \begin{align*} \frac{\tau_{\Omega_b^-}}{\tau_{\Xi_b^-}} &= 1.11\pm0.16\pm0.03, \\ \tau_{\Omega_b^-} &= 1.78\pm0.26\pm0.05\pm0.06~{\rm ps}, \end{align*} where the uncertainties are statistical, systematic and from the calibration mode (for $\tau_{\Omega_b^-}$ only). A measurement …
Design and interpret the place of present
2018
The contemporary landscape expresses in itself all the contradictions of present time, marked by the lack of a coherent thought about the transformation of places and of a clear aesthetic elaboration. So, the project must reflect not only on the relationship between man and landscape but above on the need to return to a way of dwelling that respects the places. Architecture plays a fundamental role in the reconstruction of coherence of places and reveals their beauty: through its forms, it can set up unprecedented stories of space in places in constant evolution. The thought from which the design process originates must involve the reading and interpretation of the existing places, and proc…
Pictures of Nature. Mineral Imagery in Modern French Aesthetics
2016
Thus, from antiquity to the twentieth century, figured stones have changed so many times their ontological status. They were considered collectibles, emblems of prodigiousness or of curiosity; they have been interpreted as works of art attributed to nature or to a supreme creator, in competition with the works of the artists; they were finally gazed at as case or guardians of a secret revealed in the underground and overt (at the meantime) „stone writing”. This study is devoted to the forms of mineral imagery. It is interested in enlightening the contacts between visual arts and arts of speech, between sensitive image and immaterial images, and the difficult journeys, and the indispensable …
Development of an Efficient In Vivo System (P-junc-TpaseIS(1223)) for Random Transposon Mutagenesis of Lactobacillus casei
2012
ABSTRACT The random transposon mutagenesis system P junc -TpaseIS 1223 is composed of plasmids pVI129, expressing IS 1223 transposase, and pVI110, a suicide transposon plasmid carrying the P junc sequence, the substrate of the IS 1223 transposase. This system is particularly efficient in Lactobacillus casei , as more than 10,000 stable, random mutants were routinely obtained via electroporation.
