Department of Chemistry "Ugo Schiff" & CSGI Consortium, University of Florence, via della Lastruccia, 3, 50019 Sesto Fiorentino, Florence, Italy. Electronic address:

A dynamic, rheological, and structural characterization of aqueous gel-like systems containing hydroxypropyl guar gum (HPG), borax and glycerol is presented in this paper. The role of glycerol, which is introduced as a plasticizer in the formulation, is investigated by means of B NMR and H NMR PGSTE measurements in order to clarify its contribution to the gel network formation and its interaction with borax, with whom it forms a complex. The effect of gels components on the rheological behaviour and on the activation energy related to the relaxation process of the system was assessed by means of rheology. Read More

Micro-attenuated total reflection spectral imaging in archaeology: application to Maya paint and plaster wall decorations.

Appl Spectrosc 2008 Jan;62(1):10-6

School of Physical and Chemical Sciences, Queensland University of Technology, GPO Box 2434, Brisbane, Qld 4001, Australia.

Fourier transform infrared (FT-IR) attenuated total reflection (ATR) imaging has been successfully used to identify individual mineral components of ancient Maya paint. The high spatial resolution of a micro FT-IR-ATR system in combination with a focal plane array detector has allowed individual particles in the paint to be resolved and identified from their spectra. This system has been used in combination with micro-Raman spectroscopy to characterize the paint, which was found to be a mixture of hematite and silicate particles with minor amounts of calcite, carbon, and magnetite particles in a sub-micrometer hematite and calcite matrix.

Environ Sci Pollut Res Int 2005 Sep;12(5):285-9

Laboratory of Environment Assessment, ETSIIAA, Avenida de Madrid, 57, Palencia-34004, Spain.

Goal, Scope And Background: In this paper, we attempt to elucidate the composition and origin of the orange patina on the surfaces of the West-Porch of Salisbury Cathedral by comparison to other known patinas: (i) the orange-brown patina on the marble surfaces of the Acropolis in Athens and the Arch of Titus in Rome whose analyses have shown very high amounts of phosphates, and generally amino acids from animal-skin glue or other protein binders; (ii) the phosphated patinas which also contain oxalates, found in 1996 on Catalonian calcareous sandstones and in the calcareous dolomites of the Monastery of Silos, Spain, whose origin is either the application of calcium caseinate, or egg yolk and animal glue; and (iii) the patinas with only oxalates found in some of Verona's monuments (St. Zeno) and Spanish sites as in the Monastery of Guadalupe and Cuenca cathedral, formed either by the mineralization of algal filaments or by biological reactions yielding oxalate from yolk egg (added to stone as part of preservative empirical treatments).

Methods: In the winter of 2003, the West-Porch of Salisbury Cathedral received conservation works, but the old patina was not entirely removed. Read More

Cult Med Psychiatry 2004 Sep;28(3):315-39

Department of Psychiatry and Behavioral Sciences, Duke University Medical Center, Durham, NC 27704, USA.

This paper discusses the different explanatory models and the contested perceptions of cancer etiology among residents of two Anatolian villages and migrants from these villages in Turkey, Sweden, and Germany. These communities suffer from an endemic, deadly cancer called mesothelioma, the cause of which is associated with exposure to an environmental carcinogenic substance, erionite, which is present in large deposits in the ground, in the stones, and white stucco that the villagers used to build their homes, and in the air in the form of dust. However, an examination of patients' disease trends, experiences, and local explanations has led to new investigations of possible familial risk cofactors. Read More

IARC Sci Publ 1989 (90):411-9

However, further studies have shown that tremolite occurs as a contaminant within the chrysotile ore body. Read More
