Nursing home vouchers in Spain: the Valencian experience
2002
The main purpose of this paper is to evaluate the innovative nursing home voucher scheme that was introduced by the Valencia Autonomous Region of Spain in the early 1990s to implement targets laid down by the national plan for the development of older people's services. The article begins with a review of the evolution of Spanish social services, and especially the nursing home sector, and then summarises the genesis, objectives and characteristics of the voucher scheme. The main part of the paper reports a performance analysis and economic evaluation of the programme. On the basis of detailed information over four years, it is concluded that nursing home vouchers have contributed to the in…
Rubber Forming Processes of Thin Sheets
1999
In the last decade flexible media have been increasingly utilized in sheet metal drawing processes in order to reduce the tooling cost and to improve the product quality. In the present paper an axisymmetric deep drawing process of thin steel sheets is taken into account: in particular a flexible pad is utilized in order to simplify the tooling set. The process mechanics is investigated through numerical simulations and experimental tests with the aim to find out a proper set of operative parameters allowing the stamping of sound components and to highlight the particular deformation path of the drawing cup. The comparison between the numerical predictions and the experimental verification …
Springback Evaluation In Basic Sheet Metal Stamping Processes
2000
In the present paper a measurement technique based on the shadow moire method has been set up in order to evaluate the springback phenomenon in deep drawing operations. Two proper coefficients are introduced to quantitatively describe the effect considered. In particular the proposed technique is able to acquire the final profile of the drawn parts along one or more generatrices, once extracted out from the dies and to compare such profile with the ideal one derived from the dies CAD geometry. The proposed technique has been applied to an axysimmetrical deep drawing operation and moreover the influence of the blankholder force level and of the lubricating conditions have been taken into acc…
An Optical Technique for Springback Measurement in Axisymmetrical Deep Drawing Operations
2001
Abstract In this paper, a measurement technique based on the shadow moire method has been set up to evaluate the springback phenomenon in deep drawing operations. Two proper coefficients are introduced to quantitatively describe the investigated effect. In particular, the proposed technique is able to acquire the final profile of the drawn parts along one or more lateral contour, once extracted out from the dies, and compare such profile with the ideal one derived from the dies CAD geometry. The proposed technique has been applied to an axisymmetrical deep drawing operation, and, moreover, the influence of the blankholder force level and lubricating conditions has been taken into account. T…
Environmental and Forest Planning in Italy: Conflicts and Opportunities
2016
Abstract The necessity of a more sustainable use of lands and environmental resources in general, throughout specific programming and management tools at different scale levels is nowadays widely shared. Forests and woodlands are a key asset of the environment and the traditional and current landscapes. With regards to the state of art of forest planning and management tools in Italy, in this short paper, after a synthetic analysis of the tools currently adopted at different levels, some critical aspects of the relationships of forest planning instruments with other planning tools involved in environmental management (landscape plan, energy plans, basin plans) are investigated, enlightening…
Il laboratorio di A.
2021
E allora c’è l’uso della tipografia per la composizione del testo, in forma concisa di pensieri sparsi o più strutturata di riflessioni ampie, necessarie per tenere insieme la mente e la mano, per verificare la direzione presa e correggere la rotta se necessario. C’è l’uso del progetto grafico, che di strumenti ne richiede diversi, la tipografia in primis, ma anche le forme, i colori, e poi le gerarchie, le relazioni, e su tutti la traduzione dei contenuti, un continuo processo di mediazione. C’è infine l’uso del disegno, che ha bisogno davvero di pochi strumenti per esistere, un foglio e un pennino, ovvero un piano su cui depositare una bava di inchiostro e uno in grado di spargerlo sulla …
Lo strumento della linea e il progetto di Ernesto Basile per Montecitorio
2018
Il saggio intende avviare un ragionamento sul controverso progetto di Ernesto Basile per Montecitorio, come occasione per ricondurre quest’opera nel corretto alveo di appartenenza culturale rispetto al percorso di ricerca basiliano, richiamando alcune questioni di metodo e obiettivi del lavoro progettuale dell’architetto siciliano, che ne definiscono il campo di azione teorico e operativo. Riferendosi ad uno dei temi che caratterizza maggiormente il costrutto metodologico basiliano (il tema della linea e della sua “curvatura”) si dimostra come questo coinvolga direttamente l’attuazione pratica, legando indissolubilmente il pensare al fare architettura con modalità ben rilevabili anche nel p…
House Without Rooms
2019
Una riflessione letteraria e architettonica sul progetto House Whitout Rooms di Raimund Abraham, elaborata nell’ambito del Laboratorio Aperto - Omaggio a Dedalo svoltasi al Palazzo Belmonte-Riso durante la Via dei Librai 2018. La Casa senza stanze come interno inospitale, nel quale trovare il disagio necessario per desiderare la fuga.
University Commitment and Professional Experience: Ten Questions to Marcella Aprile
2018
In this interview, which took place in Palermo, 30 January 2018, Professor Marcella Aprile (b. 1947) talks about the changes of the Italian university system after 1968 and about her commitment as a teacher. An important part of the interview is dedicated to the story of her professional experience in the reconstruction of small town Gibellina after the earthquake of 1968. The conversation also investigates the role of drawing in the design process.
Lapis Resiliency, through Analogic and Digital Drawing
2022
In recent years, life drawings as a tool for site survey had slip into the oblivion of time. Its use is considered anachronistic and superfluous in what is defined as the 'digital age'. Nevertheless, thanks to architecture students, who measure themselves with this type of competence, freehand drawing survives revealing its role in understanding the existing reality. Furthermore, the pandemic emergency has provided the opportunity to reflect on the subject, highlighting the importance of urban sketching as a tool to understand and comprehend the building environment. However, the need to adapt to remote activities has inevitably led to the development of new and interesting methodologies by…
