The heteronomy of building technologies in the construction industry in Italy. Notes for a to-do list
Full text linkA pervasive self-referential technique has characterized architecture for some decades, affecting a minor part of architectural production. Celebrated by specialist publications, it has marginally impacted current and ordinary constructions that actually transform the landscape. Addressing the latter production, the essay attempts to define and argue the heteronomous nature of technological change in the national context as a prerequisite for orienting research and design towards the pursuit of a social role of technology, considered a response to the broadest and most widespread demand. This thesis is also underpinned by the discussion of emblematic cases in the history of the Italian construction sector during the post-war period. Finally, starting from a brief outline of the structural factors of change, we intend to provide some operational reflections to rethink the relationship between design and construction
La dimensione sperimentale dell’edilizia residenziale pubblica. Alcune storie dimenticate
No full textIn the attempt to respond as widely as possible to the housing demand through high-quality low-cost solutions and in a short timeframe, social housing has been characterized, since its beginnings in Italy, by an experimental approach quite different from the more conventional of private housing. It is a story that can be told through famous examples in the history of architecture, but also by isolated or forgotten cases, proving that a very wide and articulated baggage of experimentation, research and studies did not result into a critical evaluation and in the consequent development of intervention models and approaches. This contribution aims at investigating these lesser known ‘stories’ with particular interest in the hard and soft components of the technological dimension, in its integration with the typological concept, framing them in the respective socio-economic and cultural context, highlighting the missed opportunities and, where present, the endogenous and self-referential aspects of the applied innovation, which led to its failure. In particular, with the purpose of determining a geographical limit to the research, the exploration will refer to the Lombardy area, with a preference in the choice of case studies to include different methods of innovation and interrelation with the characteristics of the context. Examples of intervention costs reduction through the rationalization of project and construction production processes, of economies of scale, as well as of prefabrication, of dry assembly systems with high durability and maintainability and of energy saving through the surface to volume ratio control will be portrayed. In conclusion, the essay intends to highlight the recurring structural, regulatory, procedural obstacles to change, and outline possible contemporary research perspectives to respond to low-cost housing demand in terms of innovation of approaches and models rather than of techniques, in light of the current condition and its evolutionary framework
Repeated nucleotide sequences in human main band DNA.
No full textMale and female human placenta DNA was fractionated in an Ag+-Cs2SO4 density gradient. The different fractions along the gradient were analyzed by Hae III endonuclease digestion. Within the main band DNA on the light side a component having a Hae III digestion pattern similar to that of human satellite III DNA has been identified. This component which might be defined as a cryptic satellite accounts for at least 3% of the total human DNA and has a different position than human satellite III in Ag+-Cs2SO4

Lotto 'O' in Ponticelli: intenti, esiti e prospettive future.
Full text linkNell’ampio panorama dell’edilizia residenziale pubblica del contesto napoletano – interessato da molteplici strategie di intervento sui quartieri periferici in condizioni più critiche – il contributo intende inquadrare il caso studio del quartiere di Ponticelli, con particolare riferimento alle aree di attuazione del Programma Straordinario per l’Edilizia Residenziale (PSER), attualmente oggetto di una proposta di recupero da parte del Comune di Napoli. Tra le aree oggetto del Programma di Recupero Urbano (PRU), il Lotto ‘O’ è un caso studio di particolare interesse, a partire dalla sua realizzazione – a metà tra l’edilizia residenziale pubblica e la costruzione post-emergenza – e dalle sue caratteristiche fisiche, che lo rendono un luogo introverso e poco integrato con il tessuto urbano circostante. Tale lotto è oggetto di studio presso il DiARC della Federico II nell’ambito del progetto europeo PUSHousing, che promuove un’indagine critica sullo spazio pubblico per la sua capacità di costruire publicness, quale occasione per l’integrazione sociale e culturale nei quartieri di Social Housing. Il contributo intende presentare l’avvio della ricerca relativa alle condizioni attuali del lotto, allo scopo di evidenziarne criticità e opportunità in relazione alle modalità e alle condizioni di utilizzo dello spazio pubblico. Tali considerazioni sono avanzate sulla base di osservazioni indirette, attuate per mezzo di analisi fisico-spaziali tese a raccogliere dati quantitativi e qualitativi sulla fisicità del quartiere, associate a indagini sperimentali che muovono dall’esperienza diretta dei luoghi studiati, finalizzate a conoscere le modalità di interazione tra le persone e lo spazio fisico. Lo studio presentato costituisce il pròdromo di un metodo di analisi esportabile, utile alla futura definizione di interventi bottom-up per declinare lo spazio pubblico come luogo dell’informalità
