During restoration works carried out under the direction of the Archaeological Superintendence of Salerno, Avellino and Benevento, a three-dimensional survey was carried out aimed at the documentation of performed restoration works, setting-up for museum exhibitions and the monitoring of the Arco di Traiano in Benevento. The potentialities of 3D documentation are wide-ranging and not only limited to the cataloguing, but aimed at different kind of development: analysis of details, planning and structuring of restoration and conservation works, 3D printing to realize scaled copies without plaster cast operations, mapping of the state of conservation. The 3D model becomes a tool of knowledge and analysis, the use of which is expected to grow exponentially in the coming years, also in relation to the increase in computing power and graphical display of devices such as notebooks, tablets, smartphones and dissemination of "broadband" for the interconnection of data transmission.

Polymer electrolyte and solid oxide are the two fuel cell types (PEFC, SOFC) under development in Switzerland. The very distinct operating temperatures of 80°C (PEFC) and 800–950°C (SOFC) impose fundamentally different requirements upon the nature of the fuel; normally purified H2 for the former (CO trace) and usually synthesis gas for the latter (H2, CO as main constituents). Apart from stored hydrogen, the most relevant fuels are primary hydrocarbons (natural gas, biogas, liquids,...), that then need processing (chemical conversion, cleaning) up to a level compatible with the fuel cell catalysts. These processes are briefly reviewed. Fuel compositions with an emphasis on impurities are given. Two application examples from Swiss R&D are presented: gasoline conversion to high purity H2 for PEFC and contaminated biogas processing for SOFC.
