Masonry wall panels retrofitted with thermal-insulating GFRP-reinforced jacketing
Today there is a need to provide thermally efficient walls, while at the same time to increase the mechanical properties of old unreinforced masonry walls that will not require large amounts of energy in the retrofitting or deconstruction processes. To address this problem, this paper gives the results of shear tests carried out on masonry panels made of solid bricks retrofitted with a new technique based on the use of glass fiber-reinforced polymers (GFRP) grids inserted into a thermal insulating jacketing. This was made of different low-strength lime-based mortars. Tests were carried out in laboratory and results were used for the determination of the shear modulus and strength of the wall panels before and after the application of the GFRP reinforcement. Retrofitted panels exhibited a significant enhancement in the lateral capacity when compared to the control panels. The thermal performance of the proposed mortars was also investigated both with and without GFRP. Low values of thermal conductivity were found, especially for the samples with GFRP; a reduction of the thermal transmittance value in the 34–45 % range was also obtained by applying 45 mm layer of coating in conventional masonry walls

Shear strengthening of wall panels through jacketing with cement mortar reinforced by GFRP grids
This paper gives the results of a series of shear tests carried out on historic wall panels reinforced with an innovative technique by means of jacketing with GFRP (Glass Fiber Reinforced Plastics) mesh inserted into an inorganic matrix. Tests were carried out in situ on panels cut from three different historic buildings in Italy: two in double-leaf rough hewn rubble stone masonry in Umbria and L'Aquila and another with solid brick masonry in Emilia. Two widely-known test methods: the diagonal compression test and the shear-compression test with existing confinement stress. The test results enabled the determination of the shear strength of the masonry before and after the application of the reinforcement. The panels strengthened with the GFRP exhibited a significant improvement in lateral load-carrying capacity of up to 1060% when compared to the control panels. A numerical study assessed the global behavior and the stress evolution in the unreinforced and strengthened panels using a finite element code
«Quante cose avrei da dirti. Ma ora non si può». La censura postale a Siena durante la Seconda guerra mondiale
Risultato di una ricerca condotta negli archivi locali e nazionali, il volume di Michelangelo Borri ricostruisce l’organizzazione e l’attività della censura postale nella provincia di Siena negli anni della Seconda guerra mondiale.
Una prima parte è dedicata alle vicende della locale commissione di censura provinciale, alla sua composizione, al funzionamento e alle trasformazioni conosciute negli anni del conflitto, dal giugno 1940 fino ai mesi successivi alla liberazione del territorio senese nel luglio 1944. A questa segue una breve raccolta di lettere e stralci di lettere ritrovati negli archivi e ordinati cronologicamente, a formare una narrazione “dal basso” degli eventi, espressione del comune sentire dei senesi in guerra, delle loro speranze, paure, emozioni
Il divenire della disciplina urbanistica: il contributo di Dino Borri
With this volume - Conversations with TeMA - the Journal opens a new editorial line specifically dedicated to promoting and disseminating the discussion between worldwide researchers on specific issues concerning the contents, methods and timing of our work.
This first experience is dedicated to a deepening, in an interview formula, on the future of spatial planning in Italy both from a regulatory and technical-disciplinary perspective, also concerning what is happening in other countries. In line with the aims we had set, we decided to involve, in this first phase, both colleagues working in Italian universities and those working in foreign universities and research centres.

Borri, Girolamo
Professor of Philosophy at the University of Pisa when Galileo was a student there, Borri was a fierce advocate of Aristotelianism. He considered Aristotle as “the true guide for philosophers” and maintained that “the whole posterity learnt more, and in a easier, better and sooner way, from him alone than from all antecedents” (Borri G. De motu gravium et levium. Marescotti, Florence, 1575, Preface)
Traditionskern’, ‘Gefolgschaft’: More Questions Than Answers
The Roman army represented an important social and organizational reference model for the Romano-Barbarian societies, which progressively replaced the Western Empire in the transition from Late Antiquity to Early Middle Ages. The great flexibility of the decision-making and organizational solutions used by the Roman army allowed the ‘new lords’ to readapt them and thus maintain power in early medieval Europe for a long time.
From a perspective ranging from political, social and economic history to law, anthropology, and linguistic, this book demonstrates how interesting and fruitful the investigation of this specific cultural imprint can be in order to gain a better understanding of the origins of the civilization that arouse after the fall of the Roman world.
