Purple Biodeterioration in Parchment: a Case in the Alcobacense Collection
Pinheiro, C; Miller, A; Bhattacharya, S; Vaz, P; Caldeira, A Teresa; Casanova, CThe understanding of purple biodeterioration, or the appearance of purple tinged stains in parchment, has seen a sharp evolution in the last few years. Modern molecular analysis of the DNA, using Next-Generation Sequencing, have made it possible to hypothesize a chain of events triggered by the presence of Archaeobacteria in the parchment, a succession theory that builds on the presence of complex biological co...
Underneath the Purple Stain
Pinheiro, C; Miller, A; Vaz, P; Caldeira, A T; Casanova, CThe Alcobacenses are one of the most important Portuguese collections of Monastic codices. During a campaign study to further advance our knowledge on this important legacy and its state of conservation, a heavily deteriorated codex (ALC.338) stood out due to the presence of purple stains on the lower margins on virtually all folios. In some of them, the purple stains are accompanied by yellow and brown patches...

Assessment of Patient Dose Reduction by Bismuth Shielding in CT Using Measureme...
Mendes, M; Costa, F; Figueira, C; Madeira, P; Teles, P; Vaz, PThis work reports on the use of two different Monte Carlo codes (GEANT4 and MCNPX) for assessing the dose reduction using bismuth shields in computer tomography (CT) procedures in order to protect radiosensitive organs such as eye lens, thyroid and breast. Measurements were performed using head and body PMMA phantoms and an ionisation chamber placed in five different positions of the phantom. Simulations were p...

Costa, F; Teles, P; Nogueira, A; Barreto, A; Santos, A I; Carvalho, A; Martins, B; Oliveira, C; Gaspar, C; Barros, C; Neves, D; Costa, D; Rodrigues, EIn 2009-2010 a Portuguese consortium was created to implement the methodologies proposed by the Dose Datamed II (DDM2) project, aiming to collect data from diagnostic X-ray and nuclear medicine (NM) procedures, in order to determine the most frequently prescribed exams and the associated ionizing radiation doses for the Portuguese population. The current study is the continuation of this work, although it focus...
