The latest issue of IIC's journal Studies in Conservation has just
been published.  The articles in Volume 54 number 1 cover a range of
conservation topics as these abbreviated abstracts of the papers

    Digital Three-Dimensional Modelling of Donatello's David by
    Frequency-Modulated Laser Radar

        By Gabriele Guidi, Alessandro Spinetti, Luca Carosso and
        Carlo Atzeni

        In this paper a laser scanner based on the operation
        principle of continuous-wave frequency modulated (CWFM)
        radar is applied to the acquisition of a digital
        three-dimensional model of the well-known David by
        Donatello. Detailed results are presented, demonstrating how
        the use of this type of sensor allows digitization of works
        of art made of materials that cannot be sampled, and
        improvement in the overall level of modelling accuracy.

    Investigation of the Brass Monument to Minin and Pozharsky, Red
    Square, Moscow

        By Anna Bogolitsyna, Bernhard Pichler, Alfred Vendl,
        Alexander Mikhailov and Boris Sizov

        Powder patina and metal bulk samples, were taken from the
        brass monument to Minin and Pozharsky in Red Square, Moscow.
        These samples were used to study the composition of the
        patina. The analyses included X-ray diffractometry, scanning
        electron microscopy and light microscopy. This investigation
        was carried out to provide experimental results for a
        comprehensive approach to restoration measures in the
        future.

    A Scientific and Historical Investigation of Italian Scagliola

        By Pietro Baraldi, Laura Cannalire and Maria Perla Colombini

        Fragments from works of art made of scagliola were
        investigated. Vibrational spectroscopic techniques were
        applied in order to identify the pigments used to tint the
        gypsum paste; in particular, Raman microscopy; pyrolysis gas
        chromatography combined with mass spectroscopy was used to
        identify binding media.

    The Effect of Ventilation, Filtration and Passive Sorption on
    Indoor Air Quality in Museum Storage Rooms

        By Morten Ryhl-Svendsen and Geo Clausen

        A study was conducted in five storage rooms at the National
        Museum of Denmark, in which the effect on indoor air quality
        of mechanical ventilation, filtration and passive sorption
        was investigated. A cautious conclusion is that a
        combination of a low air exchange rate and internal
        recirculation with filtration will be most beneficial to the
        indoor air quality for such low-activity storage buildings.

    The Impact of Air Pollution on the Paintings in Storage at the
    Museum of Modern and Contemporary Art, Rijeka, Croatia

        By Ana Alebic-Juretic and Duska Sekulic-Cikovic

        This paper aims to assess the possible impact of air
        pollution on works of art kept in storage at the Museum of
        Modern and Contemporary Art. Soiling removed during the
        process of conservation-restoration was analysed for its
        ionic content, lead, soot and polynuclear aromatic
        hydrocarbons.

Book reviews are also carried on a number of recent conservation
publications.
