To Feel, to Understand, to Act. Sustainability on Display
No full textThis essay describes the exhibition project Sostenibilart promoted by CYLAND MediaArtLab and the Centre for Studies in Russian Art (CSAR). Starting from an analysis of what is normally described with the term ‘sustainability’, we will examine how this concept is developed by the artists identified as ambassadors of sustainability. Their reflection on the theme is also expressed through the answers to three questions posed by the Author that allow a transversal reading of the project. The text will therefore consider the ideas that emerged in this interrelated exchange. Finally, we will consider participation in contemporary art to verify the significance of the contribution of the artists-ambassadors of sustainability to stimulate in the public a reflection – and eventually action – on the issues
Technical Note: Year, season, and parity effect on weaning performance of the Carmagnola Grey Rabbit breed
No full textTo evaluate the main environmental factors in the productivity of Carmagnola Grey rabbits, an endangered breed indigenous to northern Italy, data collected over 8 years were analysed. Production data on the pure closed nucleus herd of the University of Turin were used. Effects of parity, season and age of weaning on the number of rabbits born alive and weaned, litter weight and individual average weight at weaning were studied. The following average performance rates over the 8 years period were determined: 8.1 live born and 7.2 weaned kits per litter and a litter weight at weaning of 7287 g or 1024 g individual weaning weight. Year and season both had a significant effect (P < 0.001) on all the traits studied as well as weaning age (P < 0.001).Lazzaroni, C.; Biagini, D.; Redaelli, V.; Luzi, F. (2012).

Quod raro alias, praetorianus urbanusque miles in aciem deducti. Some considerations on the participation of the praetorian and urban cohorts in the civil wars of 69 A.D.: critical evaluation of the literary sources and the expedition against Narbonne Gaul (Part I)
No full textDuring the year of the four emperors the Praetorian Guard and the Urban cohorts played an important role in the military events of the civil wars. the paper examines some problems related to the involvement of these military corps in the military campaigns of AD 69. the literary sources often describe the Praetorians and the Urbaniniciani as passionate and violent, like the other milites of the Roman army, and moreover as second-rate and undisciplined soldiers; a careful analysis assesses if these descriptions are truthful or depend on the use of literary topoi and if the soldiers of urban troops were really inferior warriors to the legionaries serving on the frontier. Secondly, the paper examines accurately one of the conflicts in which the urban troops took part: the maritime expedition that Otho launched to attack Narbonense Gaul. the analysis of the literary and epigraphic documentation, thanks to new updated interpretations of the sources, fosters the acquisition of new and more precise historical information in order to reconstruct this military campaign
My Boyfriend Came Back From The War: una narrazione visiva di Olia Lialina
No full textThe contribution proposes the analysis of Net Art’s world-famous masterpiece
of one of its founders: My Boyfriend Came Back from the War (1996) by Olia Lialina.
Combining black and white images and words, it evokes the encounter of two lovers who
have been separated so long by the war. With her work, Lialina shows us the potential for
interaction of the new screen – that of the computer. She experiments with a non-linear
narration, where users edit the story frames thanks to hypermedia platform, resulting in
a new relationship between author and public. Considering such operations, the paper
aims to highlight the work’s ludic connotation beside the impact of filmic narrative on
the web
Quod raro alias, praetorianus urbanusque miles in aciem deducti. Unsolved problems and new interpretations on the movements and the composition of the urban troops during the civil wars of AD 69 (Part II)
No full textDuring the Year of the four emperors the Praetorian Guard and the Urban cohorts played an important role in the military events of the civil wars. The paper examines some problems related to the involvement of these military corps in the military campaigns of AD 69: the number of soldiers and cohorts participating in the different war scenarios, the movements and the fate of Otho’s Praetorians compared with Vitellius’ newly formed Praetorian cohorts. Moreover, in light to new interpretations of the sources, it analyzes the history and the composition of the four Urban cohorts created by Vitellius: in particular, I discuss the thesis according to which Vitellius mixed in legionaries formerly serving on the Rhine frontier and the old Otho’s urbaniciani within these new Urban cohorts
Caratterizzazione di due calcestruzzi UHPFRC commerciali: valutazione di proprietà meccaniche e di durabilità
No full textThis note presents the results of a research aimed at assessing and comparing the properties of two commercial Ultra-High-Performance Fiber Reinforced Concretes (UHPRFC) made with the same amount of steel fibers (2.5% vol.). Besides the basic properties at hardened state, such as compressive strength and elastic modulus, durability-related parameters are measured, such as electrical resistivity, resistance to carbonation and chloride penetration, water absorption rate and water absorption. Microstructure is also studied by means of optical and electron microscopy. The results show that, although fibers may locally increase the presence of interfacial voids in the cement paste and decrease the electrical resistivity of UHPFRC, both products exhibited an overall excellent behavior if compared to ordinary concrete
Carbonation-Induced Corrosion of Reinforced Concrete: Preliminary Results on the Collegi Universitari in Urbino
No full textInfluence of steel fibers on durability properties of UHPFRC
No full textUltra-high-performance fiber-reinforced concrete (UHPFRC) is a high-strength cementitious material whose composition can be designed to achieve given properties in the fresh and hardened state. Thanks to the low water/binder ratio (around 0.2) and to the presence of mineral additions, it is characterized by a low porosity which is often taken as a guarantee of intrinsic - almost unlimited - durability. However, the number of researches on the long-term behavior of this type of material is relatively limited, in particular with respect to the corrosion behavior of steel and to the role of steel fibers on concrete durability. This note presents the results of a research aimed at studying the influence of fibers on durability properties. Besides tests for the characterization at fresh and hardened state, durability-related parameters such as electrical resistivity, resistance to chloride penetration, absorption rate and water absorption are investigated. The results show that higher amount of fibers increased the porosity of fibers-concrete interfacial zone and therefore large fibers content negatively influences the parameters related to durability. However, the investigated parameters indicate higher performances with respect to ordinary concretes even in UHPFRC with large fiber content, except for electrical resistivity
