Foreigners in San Siro: living between marginality and regaining. Stranieri a San Siro: abitare tra marginalità e riscossa.
No full textLa ricerca affronta il tema della povertà abitativa per la popolazione straniera nel quartiere ERP di San Siro, a Milano, presente in percentuali estremamente elevate rispetto alla popolazione totale. La dimensione socioeconomica che caratterizza il quartiere milanese nella sua attuale conformazione è il frutto di progressive trasformazioni urbane, avvenute sul lungo periodo attraverso una continua interazione tra evoluzioni storiche e politiche, che hanno contribuito a definire i dirompenti stravolgimenti degli ultimi decenni. L’indagine dimostra come, tra le principali cause
dell’aumento di disuguaglianza, esclusione e conflitto a San Siro, abbia svolto un ruolo determinante la totale assenza di adeguate politiche sociali di sensibilizzazione e integrazione che, negli anni, avrebbero potuto accompagnare le rapide trasformazioni nella composizione sociale del quartiere.The research deals with the issue of housing poverty for the foreign population in the public housing district of San Siro, in Milan, that makes the dominant part of the total population. The current social and economic structure of the place has been built, over time, on the basis of an inseparable link with the main historical and political events, leading to the disruptive and profound transformations of recent decades. The survey shows how, among the main causes of the increase in inequality, exclusion and conflict at San Siro, the total absence of adequate social policies of raising awareness and integration that, over the years, could have accompanied the rapid transformations of the neighborhood, played a decisive role
Metal complexes of oxadiazole ligands: An overview
Full text linkOxadizoles are heterocyclic ring systems that find application in different scientific disciplines, from medicinal chemistry to optoelectronics. Coordination with metals (especially the transition ones) proved to enhance the intrinsic characteristics of these organic ligands and many metal complexes of oxadiazoles showed attractive characteristics for different research fields. In this review, we provide a general overview on different metal complexes and polymers containing oxadiazole moieties, reporting the principal synthetic approaches adopted for their preparation and showing the variety of applications they found in last 40 years
Urban spaces as mirrors of multiple social identities: The palestinian people of Israel
No full textThis study focuses on different groups of Palestinian citizens of Israel, representing more than 20% of the total Israeli population. Working on the link between urban space and social diversity, the authors will capture complex dynamics of segregation and social inequalities existing among different Arab communities. This research aims to promote a new approach that, overcoming the stereotyped vision of two social monolithic blocks at war with each other - Jews and Arabs- shows a complex social mosaic of multiple cultural identities, characterizing the contemporary Israeli society
La corsa alla casa nella città attrattiva: l’inserimento abitativo dei giovani a Milano.
No full textImprovement of a multiphase flow model for wellhead chokes under critical and subcritical conditions using field data
No full textThe characterization of the multiphase flow through valves and orifices is a problem yet to be solved in engineering design, and there is a need for a prediction model able to simulate the complexity of this kind of flow in relation to fluid thermodynamic behaviour, and applicable to different incoming stream conditions and compositions. The present paper describes the development of a global model for the calculation of the discharge coefficient of orifices and choke valves operating under two- and three-phase flow as well as critical and subcritical conditions. The model generalizes the hydrovalve model developed by Selmer-Olsen et al. (in: Wilson (ed) Proceedings of 7th international conference on Multiphase Production, BHR Group, pp 441–446, 1995) and the Henry–Fauske (J Heat Transfer 93: 179–187, 1971. https://doi.org/10.1115/1.3449782) non-equilibrium model on the basis of an updated definition of the discharge coefficient. The model has been adapted to real choke valve geometries, by fitting the discharge coefficient and model parameters using field data from three production wells. The model developed is a global quartic function with different constants for the different valve geometries. The new discharge coefficient allows to simulate field data with high accuracy

Review on electric vehicles exterior noise generation and evaluation
No full textThe increasing worldwide adoption of Electric Vehicles promises to deliver a number of positive impacts, not only on the environment, but also on the quality of life of citizens in urban scenarios. However, the absence of exterior sound in Hybrid and Electrical Vehicles, especially at low speeds, may negatively affect pedestrian safety. While regulations mandate the adoption of Acoustic Vehicle Alert Systems, they also leave freedom to manufacturers and sound designers to find proper warning sounds, able not only to fulfill safety requirements but also to preserve the brand identity. This paper presents the most relevant initiatives around warning sound design, from the scientific state-of-art to the industrial implementations and R&D projects, taking into account the warning sound assessment methodologies imposed by regulations
Operationalizing urban resilience: insights from the science-policy interface in the European Union
No full textBy examining three policy-oriented research projects funded by the European Union (RAMSES, RESIN, SMR) the paper critically discusses operationalization efforts of urban resilience as they are designed and produced at the interface between science and policy. By analysing the documents and conducting interviews with the projects’ coordinators and participants, three main research questions were addressed concerning how urban resilience is defined across the projects and the actors involved, the role of the tools produced by them in their difficult task to reconcile wider applicability and local specificity and finally how stakeholder engagement and co-creation were framed and implemented. Based on the evidence collected, the authors argue that conceptualizations of urban resilience within operationalization efforts being produced at the science policy-interface are still quite plural and open, that such openness is largely confirmed by the flexibility of the tools produced by the projects and that while becoming increasingly relevant stakeholder engagement and co-creation strategy are yet to be fully framed and theorized. Finally, they present further research pathways aimed at strengthening our knowledge of operationalization efforts, the role of practitioners and of urban resilience implementation in discrete scientific and political environments
