Ancora una possibilità, tra natura e rovina: Territori post-minerari in Sardegna
No full textDalla seconda metà del Novecento la storia mineraria della Sardegna subisce un drastico processo di declino, il cui portato è oggi un vasto patrimonio abbandonato di edifici, infrastrutture, discariche. Parte di questo patrimonio – questa è la tesi che si sostiene - non potrà probabilmente entrare in un processo di riuso, ma potrà viceversa assumere un senso come rovina della contemporaneità.
La riflessione prende le mosse studiando il territorio dell’Iglesiente, nella Sardegna sud-occidentale, dove la sproporzione tra la quantità di luoghi abbandonati, spesso di notevole valore architettonico e memoriale, e le risorse economiche e in termini di attività che ragionevolmente potrebbero rifunzionalizzarli è enorme. In questo quadro il progetto e le politiche territoriali dovranno assumere un approccio selettivo: non tutto potrà essere oggetto di riuso e/o di patrimonializzazione, e andranno esplorati altri modi per tenerne in vita la memoria o eventualmente accompagnarne il declino. In particolare, ci si soffermerà sulle diverse intensità dell’azione progettuale di volta in volta praticabili: riuso dove le condizioni dei manufatti e delle risorse attivabili lo consentiranno; messa in sicurezza dove nuove funzioni non si potranno installare; rovina nei casi di maggiore
criticità. Tre possibili gradi di trasformazione che agiscono su singoli luoghi ma che per essere efficaci devono essere sostenuti da opportune visioni territoriali che riattivino una percorribilità diffusa delle reti esistenti, senza la quale è difficile che il processo di declino possa essere invertito
CERN, HL-LHC Project: numerical modelling and design challenges for the new underground facilities at Point 5
No full textThe most powerful underground particle accelerator, known as Large Hadron Collider (LHC), is located at CERN on the border between Switzerland and France. The High-Luminosity (HL-LHC) Project will increase existing facilities with new underground and shallow structures at Point 1 (ATLAS, Switzerland) and Point 5 (CMS, France). The new underground structures include a shaft, a wide cavern, 500 meters of galleries and some vertical linkage cores. This paper presents the main challenges of the Project at Point 5 describing the design and construction issues encountered for the underground structures, together with the key role of the numerical modelling in the design. The main challenges of the construction were related to the following: i) meeting the tight schedule of design and construction ii) defining design criteria i.e. calculating expected excavation-induced vibrations and minimizing the disturbance effects on the LHC where experiments were in progress; iii) excavating within a complex rock mass with several known challenging characteristics; iv) assessing the potential impact of the excavation works on the nearby existing underground structures. The excavation of the main underground works was successfully completed without any critical impact on the nearby existing underground structures. The construction phase is on track for completion within the stipulated contractual Construction Programme. The completion of the entire works is scheduled for September 2022

High-pressure behavior of intermediate scapolite : compressibility, structure deformation and phase transition
No full textScapolites are common volatile-bearing minerals in metamorphic rocks. In this study, the high-pressure behavior of an intermediate member of the scapolite solid solution series (Me47), chemical formula (Na1.86Ca1.86K0.23Fe0.01)(Al4.36Si7.64)O24[Cl0.48(CO3)0.48(SO4)0.01], has been investigated up to 17.79 GPa, by means of in situ single-crystal synchrotron X-ray diffraction. The isothermal elastic behavior of the studied scapolite has been described by a III-order Birch–Murnaghan equation of state, which provided the following refined parameters: V0 = 1110.6(7) Å3, KV0 = 70(2) GPa (βV0 = 0.0143(4) GPa−1) and KV′ = 4.8(7). The refined bulk modulus is intermediate between those previously reported for Me17 and Me68 scapolite samples, confirming that the bulk compressibility among the solid solution increases with the Na content. A discussion on the P-induced structure deformation mechanisms of tetragonal scapolite at the atomic scale is provided, along with the implications of the reported results for the modeling of scapolite stability. In addition, a single-crystal to single-crystal phase transition, which is displacive in character, has been observed toward a triclinic polymorph at 9.87 GPa. The high-pressure triclinic polymorph was found to be stable up to the highest pressure investigated

Starchitecture: Scenes, Actors and Spectacles in Contemporary Cities
No full textHow and why do spectacular buildings get commissioned and procured? What are their visible urban effects? What can urban planners, architects, and policymakers learn in order to engage in more successful citymaking?
In recent years, media and critical attention has been lavished on famous architects, and the contributions of their designs to the branding of cities. The post-“Bilbao effect” global landscape is one where cities compete for the highest-profile skyscrapers, cultural projects, and high-profile developments designed by star architects whom even casual readers know by first name: Frank Gehry, Bjarke Ingels, Jean Nouvel, Zaha Hadid, Norman Foster, Rem Koolhaas. Far less is known about the decision-making processes behind these projects and their subsequent urban effects.
A unique combination of urban studies and photography, Starchitecture investigates projects designed by star architects in cities including Paris, New York, Abu Dhabi, Bilbao, and the architectural microcosm of the Vitra campus in Weil am Rhein, Germany. Author Davide Ponzini and photographer Michele Nastasi seek to explain and critique a growing global condition by revealing how starchitecture has been and continues to be deployed in cities around the world. The arguments they raise are vital to understanding the urban landscapes of today, and tomorrow
