Social Housing in Tuscany between Urban Integration and Segregation
No full textIl contributo illustra i risultati dell'analisi configurazionale degli insediamenti edilizia sociale in alcune città toscane, così da illustrare le caratteristiche configurazioni che accomunano gli interventi più rappresentativi e le capacità di tale tecnica di analisi spaziale di portarli alla luce. Ciò attesta che gli aspetti patologici che caratterizzano tali porzioni di aggregato urbano non sono (o quanto meno non sono solamente) l'effetto di fattori di natura sociale, né il risultato di soluzioni morfologiche e compositive, quanto l'esito di specifiche scelte localizzati e della conseguente realizzazione della particolare griglia dei percorsi che sostanziano l'urbanizzazione. Le medesime risultanze appaiono anche utili a suggerire le più opportune linee di intervento per gli interventi di riqualificazione
Social Housing Neighborhoods in Tuscany: Analysis, Issues and Guidelines for Integration and Urban Redevelopment
No full textThis research is a part of the project called “Territorial emergency: implementation of social housing heritage with LC/HP strategies”, especially referring to the urban aspects of social housing neighborhoods. As our disciplinary field is represented by urban and territorial planning, we will focus on the social dimension and historical evolution of settlement processes within the sector of social housing. The research applies to the existent heritage, with the purpose of concurring in defining new conceptual and operational tools for its management and recovery

No full textModelling and Design of an Articulated Device for Pouring Concrete
No full textThe aim of the work is the implementation of a sound virtual model to predict the on-field behaviour of an articulated 58-meter device for pouring concrete in building constructions. The objective is an accurate study of the structure to optimize its performance in operative conditions. An already existing prototype of the rig can be carried by a tractor unit (on which it is located and to which it is joined), it is composed of five arms and it can be used to pour concrete at different heights, by assuming different configurations (deriving by all the allowable relative positions of the five arms). This prototype has been instrumented with rectangular rosettes to verify its behaviour experimentally. At the same time, a CAD 3D model has been implemented by a modeller and used to perform a finite element analysis of the structure. Numerical predictions and experimental data have been compared: a very good correlation results. Experimental validation confirms the soundness of the virtual model. Numerical simulations performed on the model lead to interesting suggestions for the optimization of the geometry and to the set-up of an out-of-service experimental testing apparatus for the device itself or for its future upgrades
Gracilis muscle transposition for the treatment of recurrent rectovaginal and pouch-vaginal fistula: is Crohn's disease a risk factor for failure? A prospective cohort study
No full textBACKGROUND:
The surgical management of rectovaginal fistulae associated with Crohn's disease is often frustrated by poor results regardless of the different techniques. The outcomes of the gracilis muscle transposition (GMT) for the treatment of recurrent Crohn's-associated fistulae are still debated. The aim of the study is to determine whether the success rate of GMT is similar in Crohn's disease patients and in a control group.
MATERIALS AND METHODS:
All patients undergoing GMT for rectovaginal or pouch-vaginal fistula were collected from a prospectively maintained database (2005-2016). The primary study outcome was the comparison of the success rate of GMT in Crohn's disease and control group patients.
RESULTS:
Twenty-one patients with a rectovaginal fistula due to Crohn's disease (8, 38.1%) or other etiologies (13, 61.9%) were included. The groups had similar characteristics and postoperative outcomes. After a median follow-up time of 81 and 57 months (p 0.34), the success rate of GMT was 75% in patients with Crohn's disease and 68.4% in control group (p 0.6). The median time to recurrence was 3.5 months (1-12). The success rate in patients who had more than two previous attempts of repair was lower regardless of the etiology (50 vs 79.4%, p 0.1).
CONCLUSION:
GMT is associated with a high success rate, especially in Crohn's disease-related rectovaginal fistula. In consideration of the low morbidity rate and the fact that an increasing number of previous local operations might be associated with failure, the procedure should be considered as a first line of treatment for recurrent rectovaginal fistulae

High Performance Strategies for House Design: a Mine in the Atacama Desert
No full textOut of the architectural typologies that emerged in countries with a rough, arid and hot climate we synthesized the principles that laid the foundations of applied theories in bioclimatic and sustainable architecture. The accumulated experience is visible in their vernacular architecture, clearly showing the layers of attempts, adaptation and knowledge merging towards the best adaptive model of architecture to the harsh context. Some of the more prominent features of this type of architecture is constant search of cooling techniques, such as shading, designed to be protected by direct sunlight. There has been little to none improvement to this type of architecture for a long period as no real value could have been added to this already functional ancient systems. But today, with the help of modern technology, one can use parametric design in order to further optimize this architecture and push it to an even more effective response to context
