Este projecto identifica os impressores portugueses do século XVII representados no fundo de livro antigo presente no acervo geral da Biblioteca da Faculdade de Letras da Universidade de Lisboa, incluindo aqueles cujas oficinas de impressão não granjearam a glória da dinastia Craesbeeck, mas que, de igual modo, têm lugar cativo na história da tipografia portuguesa. Identificando-os, quantificando-os e enquadrando-os historicamente esperamos conseguir mostrar que não é apenas nas Bibliotecas Públicas com carácter patrimonial como a Biblioteca Nacional e a Biblioteca Municipal de Évora, que se encontram depositados testemunhos importantes para o estudo da tipografia portuguesa. Pretende-se mapear o fundo do século XVII, tentando, na medida do possível, reconstituir a sua história através das pistas deixadas nos exemplares que denotam a proveniência de colecções integradas e, através da análise dos dados disponíveis, contribuir para um melhor conhecimento da tipografia portuguesa do século XVII.

In 1543 Nicolas Copernicus published his Revolutionibus Orbium's Coelelestium. This is the scientific work that gave birth to modern science, something thoroughly European, since scientists of different countries contributed to it: Poland, Italy, Germany, Spain, France, Holland, etc. A work that appeared in a crucial moment obviously represented the need of that time to correct the Julian calendar. A new procedure to calculate the positions of the stars was necessary for astrology and for the making of predictions that were important at that time. Our intention is to outline the history of how it was introduced in Spain at the beginning of the scientific revolution. We will not conceal that Spain has been a country that has only contributed to scientific literature in a deficient way, maybe we can offer some arguments that help to understand why this has happened.

The case study of Lusoponte illustrates the concession awarded by the Portuguese Government to finance, design, build and operate two bridges over the Tagus in Lisbon, Portugal. It includes an overview of the project's background and an analysis of the main risk categories stating both the actual risks encountered and the mitigation measures adopted. Throughout the project a great attention was given to whole life cycle costs, and gains in efficiency and cost control. Among the lessons that can be learned from both the public and private sector is that a complete risk management analysis must include not only the technical factors but also a realistic assessment of environmental and social risks. These were the risks that were somewhat overseen and that caused the main problems to the project's development.

The availability of population-specific normative data regarding disease severity measures is essential for patient assessment. The goals of the current study were to characterize the pattern of ankylosing spondylitis (AS) in Portuguese patients and to develop reference centile charts for BASDAI, BASFI, BASMI and mSASSS, the most widely used assessment tools in AS. AS cases were recruited from hospital outpatient clinics, with AS defined according to the modified New York criteria. Demographic and clinical data were recorded. All radiographs were evaluated by two independent experienced readers. Centile charts for BASDAI, BASFI, BASMI and mSASSS were constructed for both genders, using generalized linear models and regression models with duration of disease as independent variable. A total of 369 patients (62.3% male, mean ± (SD) age 45.4 ± 13.2 years, mean ± (SD) disease duration 11.4 ± 10.5 years, 70.7% B27-positive) were included. Family history of AS in a first-degree relative was reported in 17.6% of the cases. Regarding clinical disease pattern, at the time of assessment 42.3% had axial disease, 2.4% peripheral disease, 40.9% mixed disease and 7.1% isolated enthesopatic disease. Anterior uveitis (33.6%) was the most common extra-articular manifestation. The centile charts suggest that females reported greater disease activity and more functional impairment than males but had lower BASMI and mSASSS scores. Data collected through this study provided a demographic and clinical profile of patients with AS in Portugal. The development of centile charts constitutes a useful tool to assess the change of disease pattern over time and in response to therapeutic interventions.
