The user’s perspective in architectural heritage
No full textCurrently, the awareness has been widely acquired that appropriate use is an important condition for saving architectural heritage: as well as many others requisites (manageability, maintainability, and security) similarly accessibility has become common to any settlement, including the built heritage.
Keeping in mind this general framework, the paper will outline the link between architec- tural heritage and the user’s perspective, intended as the paramount basis both of technological design and health science.
The intertwined relationships between socio-cultural and economical aspects clarify the features of the use of this specific form of built environment, proposed as a thought provoking application field to be focused on within the Environmental Design
La passeggiata di quartiere: un progetto di partecipazione per la valorizzazione di un paesaggio condiviso
No full textNell’odierna società la riscoperta del paesaggio testimonia il bisogno della collettività di riallacciare il proprio legame con i luoghi che gli eccessi della modernità hanno spezzato. In questa direzione, un elemento mediatore materiale e culturale della dialettica uomo-paesaggio è la passeggiata di quartiere intesa come racconto identitario dei luoghi ma anche come narrazione di un legame che l’individuo instaura con essi, esclusivo e, al tempo stesso, condiviso in quanto esito di dinamiche sociali e relazionali.
Su tali premesse, si fonda il presente lavoro che intende illustrare come questa particolare esperienza sia in grado di concorrere alla conoscenza delle specificità paesaggistiche ed al processo di percezione collettiva delle stesse

Microspore embryogenesis in Citrus and in other fruit crops
No full textConventional methods, involving several generations of selfing, are not applicable to produce homozygous lines in Citrus as well as in the other fruit crops, due to the high heterozygosity of the genomes, the long duration of the generation cycle, the large size, and, often, the self-incompatibility. For this reason, there is no different way to obtain homozygosity in this kind of plants than â gametic embryogenesisâ that allows the development of haploids (Hs, plants with gametophytic chromosome number) and doubled haploids (DHs, haploids that have undergone chromosome duplication) from heterozygous parents in a single step. Therefore, gametic embryogenesis is increasingly object of research for fruit breeders. There are several available methods to obtain Hs and DHs, and among them, microspore embryogenesis through in vitro anther or isolated microspore culture is the most effective and widely used. The aim of this report is to provide some background, recent advances and future prospective of the application of microspore embryogenesis to some fruit crops and particularly to Citrus
