From Paper Manual to AR Manual: Do We Still Need Text?

Abstract In this work, we proposed a method to reduce text in technical documentation, aiming at Augmented Reality manuals, where text must be reduced as much as possible. In fact, most of technical information is conveyed through other means such as CAD models, graphic signs, images, etc.. The method classifies technical instructions into two categories: instructions that can be presented with graphic symbols and instructions that should be presented with text. It is based on the analysis of the action verbs used in the instruction, and makes use of ASD Simplified Technical English (STE) for remaining text instructions and let them easier to translate into other languages

Effects of municipal solid waste- and sewage sludge-compost-based growing media on the yield and heavy metal content of four lettuce cultivars

Compost has been recently suggested as an alternative to peat for the preparation of growing substrates in soilless cultivation systems. However, some physico-chemical properties of compost may reduce plant performance and endanger the quality of productions, in particular for possible heavy metal accumulation in edible parts. This study aims at evaluating the suitability of a municipal solid waste compost (MSWC) and a sewage sludge compost (SSC) as components of growing media for the soilless cultivation of lettuce (Lactuca sativa L.). Heavy metal content of SSC complied with legislation limits but, in MSWC, it exceeded (Cu, Pb) or was very close (Cd, Zn) to safe limits. A greenhouse experiment was carried out by cultivating four lettuce cultivars (“Maximus,” “Murai,” “Patagonia,” and “Aleppo”) in pots containing a mixture of MSWC and perlite (MSWC + P), SSC and perlite (SSC + P), or peat and perlite (peat + P), the latter used as control. Plant biometric parameters measured after 72 days of growth revealed that the yield of plants cultivated on SSC + P was similar to control plants, independently of the cultivar. Conversely, MSWC + P suppressed in general the biomass production, especially for Murai and Patagonia cultivars. Compared to peat + P, both compost-based substrates reduced the leaf accumulation of heavy metals, with a major effect in Maximus plants. The levels of Cd and Pb in the edible part were always below the safe limits imposed by European regulation. Therefore, risks of heavy metal intake in food chain associated with the replacement of peat with compost in the growing media are negligible, even when a compost with a significant amount of heavy metals is used. Besides compost quality monitoring, also an appropriate varietal choice is crucial to obtain good yields and safe products

Identità, cultura teatrale, tempo libero e territorio. Il ruolo della Fondazione Lirico Sinfonica Petruzzelli e Teatri di Bari

Identity, culture theatre, leisure time and territory. The role of the Foundation of theaters and opera symphony Petruzzelli in Bari What is the cultural heritage of a place? What are the signs that impress on space? How these signs are preserved and passed down over time? The attempt to answer these questions gave rise to this contribution which focuses on the use and organization of leisure time, man's basic spiritual need that can cause forms of territorial organization that leave indelible anthropogenic marks, expression of human 'identity’. These signs are translated into a set of status symbols especially in the urban milieu: this is the case of the Petruzzelli Theater in Bari, where it fully expresses the culture of Apulia and its capital, reborn after the fire of 1991, thanks to the wise protection and conservation carried out by local actors and, in particular, the Foundation of theaters and opera symphony Petruzzelli in Bari
