Estensive Restoration of the Colombo Bridge (Sardinia)
No full textThe Colombo bridge was built across the Mannu river in Sardinia, (Italy) between 1966-68. This bridge consists of 15 spans, each 15 m in length, 12 of these span the Mannu river and 3 span a railway.
The bridge deck is constructed out of precast pretensioned concrete I-beams, 0.80 m spacing with overlaid precast parts. It is based on a continuous pier cap, which is supported by 4 piers, each made of 2 circular columns. Continuous foundation beams distribute loads down to 0.60 m reinforced concrete piles.
In 1992 serious static damage was identified and the 2 circular columns were connected together, thus becoming a unique structure.
In 2002 due to increased heavy traffic, serious static risk and serious deterioration of the building materials, a total renovation of the structure including all structural aspects, from bridge deck to foundation piles was undertaken.
Core samples of the concrete from the piers and foundation were examined and reinforcing rebars mapped, direct load testing on the foundation piles were also carried out.
The renovation project, the extensive non destructive experimental tests and the testing of the load carrying capacity of the piles are disclosed in the following report

Orbit design for future SpaceChip swarm missions in a planetary atmosphere
No full textThe effect of solar radiation pressure and atmospheric drag on the orbital dynamics of satellites-on-a-chip (SpaceChips) is exploited to design equatorial long-lived orbits about the oblate Earth. The orbit energy gain due to asymmetric solar radiation pressure, considering the Earth's shadow, is used to balance the energy loss due to atmospheric drag. Future missions for a swarm of SpaceChips are proposed, where a number of small devices are released from a conventional spacecraft to perform spatially distributed measurements of the conditions in the ionosphere and exosphere. It is shown that the orbit lifetime can be extended and indeed selected through solar radiation pressure and the end-of-life re-entry of the swarm can be ensured, by exploiting atmospheric drag
Guillaume de Palerne en prose : quelques notes de lecture
No full textComposed by Pierre Durand shortly before 1530, the prose version of Guillaume de Palerne presents many features worth of interest; this article analyses in particular the terms in which the author intervenes in the text, to refer to his verse model and to comment on the new romance he is in the process of constructing. As a result of these interventions, the prosateur is very much a presence in his text, and one ready to share with his readers his own moral interpretation of the story.Rédigée peu avant 1530 par Pierre Durand, la version en prose de Guillaume de Palerne présente plusieurs caractéristiques dignes d’intérêt ; cet article analyse en particulier les prises de parole de l’auteur pour désigner la source en vers et pour commenter le nouveau récit qu’il est en train de construire. Il en ressort l’image d’un prosateur bien présent dans son texte et prêt à en offrir une interprétation morale à partager avec ses lecteurs
