The Renewed City. New Settlement Principles for the "Re-Construction" of the Urban Form in the Disused Areas

The paper will deal with the theme of "re-construction" of the urban form in the areas made available by the industrial, military or infrastructural dismantling processes. Assumed as a "resource" for the contemporary city (often for their "strategic" position), these areas offer the opportunity to focus and experiment new settlement principles capable not only to resolve (on the morphological, spatial and functional level) the relation between the parts of city that were previously divided but, above all, to combine the compact and continuous condition of the city with the presence of wide empty spaces of "nature", intentionally re-introduced into the new urban context. Accepting the challenge of re-building our cities in order to make them corresponding to the aspirations of our time (sustainability, livability, well-being), our research proposes an alternative response to the current settlement "practices". Against the principles of "dispersion", that means the "pervasive" occupation of the urban and suburban soil and the indifference to the peculiarities of the places, it proposes the principle of "densification" and "compaction" of the built volumes in morphologic units that, besides being evocative of the urban condition, are capable to confer to the empty spaces, inside or between them, the value of public places defined by their reciprocal relation. The purpose of this approach is to subtract the empty space (natural or artificial) to its destiny of residual undefined space between "solitary" buildings, in order to give it a higher value: to contribute to the definition of form of the city of our time

Search for Higgs boson pair production in events with two bottom quarks and two tau leptons in proton-proton collisions at √s=13 TeV

A search for the production of Higgs boson pairs in proton-proton collisions at a centre-of-mass energy of 13TeVis presented, using a data sample corresponding to an integrated luminosity of 35.9fb(-1) collected with the CMS detector at the LHC. Events with one Higgs boson decaying into two bottom quarks and the other decaying into two tau leptons are explored to investigate both resonant and nonresonant production mechanisms. The data are found to be consistent, within uncertainties, with the standard model background predictions. For resonant production, upper limits at the 95% confidence level are set on the production cross section for Higgs boson pairs as a function of the hypothesized resonance mass and are interpreted in the context of the minimal supersymmetric standard model. For nonresonant production, upper limits on the production cross section constrain the parameter space for anomalous Higgs boson couplings. The observed (expected) upper limit at 95% confidence level corresponds to about 30(25) times the prediction of the standard model. (C) 2018 The Author. Published by Elsevier B.V

Are there any subgenomic forms of hepatitis C virus RNA in the liver?

Hepatitis C virus has a single stranded positive RNA genoma. Although believed to replicate via semi-conservative transcription of a negative-stranded, genomic-length RNA intermediate, detailed steps of its replicative cycle are unknown

Sicurezza e Identità. La ricerca di modelli insediativi per la ricostruzione post-sisma / Safety and Identity. The search for settlement models for post-earthquake reconstruction

Safety and Identity appear as the opposite ends of a problem of our time that imposes a challenge to the researchers of disciplines that deal with territories, urban settlements and architectural heritage. A challenge that should be faced through integrated approaches capable of overcoming “specialisations” and experiment interdisciplinary research and projects. The DICAR Department of Politecnico di Bari is conducting theoretical and applied research on the issues of seismic disaster prevention and post-earthquake reconstruction. The methodological goal of this research is to the strategic choices for restoration, reconstruction and new construction not by rules developed on a “sectoral” basis but by principles that should be the result of an integrated approach able to combine the most strictly “technical” reasons with the reasons of built forms and their meanings, regarding architectural, urban, and landscape characteristics. With the awareness that, when appropriately considered, the latter can direct the choices relative to the first and lead to recognizable and shared formal solutions, able to achieve security and identity at the same time
