The crystal structure of jervisite, ideally NaScSi2O6, was refined using single-crystal X-ray data collected using a crystal from the Seula quarry (Baveno, Verbano-Cusio-Ossola province, Italy). The refinement was carried out in the C2/c space group giving the following unit-cell dimensions: a 1⁄4 9.8478(2) Å, b 1⁄4 9.0575(1) Å, c 1⁄4 5.3409(3) Å, b 1⁄4 106.87(2)8, and V 1⁄4 455.89(2) Å3for Z 1⁄4 4. The previous crystal structure, refined using data from a synthetic analogue and a natural sample, was confirmed and conforms with that of aegirine. The bond-valence calculation and the refined occupancy of the M1 and M2 sites confirm the cation distribution adopted in the empirical formula. Raman spectroscopy and refractive index measurements were also performed, and the morphology was studied in order to provide a complete description of this Sc-bearing Na pyroxene.

The interview treats Claes-Göran Borg’s experiences fromworking with the Swedish Space Corporation (SSC), primarily inhis capacity of developing various aspects of remote sensing andeventually his role in the management of its operations, and laterthat of the entire corporation. Claes-Göran Borg describe variouscollaborations that he and SSC contributed to that led to newforms of processing satellite remote sensing data, expanding theinfrastructure of receiving and processing such data bothnationally and internationally, and the commercialization of datathrough projects in developing countries. Claes-Göran Borg sharehis experiences of working with different people in leadershippositions and also his efforts to expand the expertise of SSC., Denna intervju har genomförts inom ramen för projektet ”50 år i rymden” som bedrivs vidAvdelningen för historiska studier av teknik, vetenskap och miljö vid KTH, finansierat avRymdstyrelsen och Vinnova.

Nella chiesa di San Gervasio e Protasio a Baveno (VB), all'interno della quali sono reimpiegati elementi di architettura funeraria noti da tempo, è stata recentemente riscoperta una lastra di notevoli dimensioni, purtroppo molto rovinata a causa del reimpiego forse come mensa di altare. Il manufatto, che doveva far parte di un recinto funerario, è decorato nella porzione inferiore da una scena inferiore, mentre nella parte superiore si notano ancora i fori per l'inserimento di elementi ornamentali in metallo.
