O controlo do circuito, da tramitação, da recuperação dos documentos e a legislação nos arquivos municipais de Moçambique

Este estudo tem como objectivo conciliar aspectos da Arquivística à Boa Administração através da gestão dos documentos com efoque no controlo do circuito, da tramitação, da recuperação dos documentos e a legislação nos arquivos municipais em Moçambique no período 1933-2007. O estudo realizado em três universos: municípios de Maputo, da Beira e de Quelimane, em que se confirma que os instrumentos de controlo utilizados na circulação e recuperação dos documentos contribuem para uma boa governação, garantindo a transparência dos actos administrativos e a salvaguarda dos direitos dos cidadãos. Mostra-se que nunca se deve prescindir quer das actividades que delineiam os macro e micro processos nas instituições quer da definição prévia dos percursos documentais, da regulamentação dos procedimentos, da utilização de técnicas que permitam a recuperação dos documentos e da informação: Mostra-se a importância da formação e do conhecimento dos procedimentos pelos funcionários dos escalões autorizados a realizar, pareceres e despachos, da determinação das formas do controlo documental e da garantia no cumprimento dos prazos estabelecidos para cada percurso e, finalmente, a necessária observância prática da legislação criada para esse efeito. ABSTRACT; This case study has as a main objective the reconciliation of the filing aspects with a good Administration though the management of documents and its network, specially in the restoring of files and its legislation into the Municipal Archives of Mozambique during the period of 1933-2007. The study was based on three cities where municipal councils were created, namely: Maputo, Beira and Quelimane. Record's contrail tools used either for registering record transactions or for the access of information contained in them, ensure good governance, transparency and protection of citizen rights. We show the necessity of the activities which lead to macro and micro processes within the organization. This requires that records procedures on transactions must be established and so the guidelines for records' contrail, registration and tools for the information retrieval. We indicate procedures to be followed by authorized civil servants, the importance of their practical training and we define types of records' contrail to ensure their preservation and use in order to accomplish the national legislation.

José de Escovar at the Chapel of the Souls: Technical and Material Study of a 1603 Panel Painting

This article reports the preliminary results of a technical and material study carried out on a 17th century panel painting located at the Chapel of the Souls in the main church of Vila Nova da Baronia (30 km away from Evora city, in southern Portugal). This painting is attributed to Jose the Escovar, a painter that worked for Evora Archiepiscopate between 1583 and 1622. Jose the Escovar is known by his mural paintings all across the Alentejo region. This is the first time that a panel painting made by this artist was studied. Analytical methods used included in situ technical photography (visible (Vis), raking light (RAK), infrared (IR), and ultraviolet (UV)), optical microscopy of cross sections, scanning electron microscopy with energy dispersive X-ray spectrometry (SEM-EDS), micro Raman spectroscopy, and micro Fourier transform infrared spectroscopy (m-FT-IR). The goal was to ascertain the techniques and colored materials used by Escovar on this painting so that the data can be used in future comparisons with others works attributed to this painter based on stylistic aspects.

New insight on the underdrawing of 16th Flemish-Portuguese easel paintings by combined surface analysis and microanalytical techniques

This paper focusses on the study of the underdrawings of 16th century easel paintings attributed to the workshop of the Portuguese-Flemish Master Frei Carlos. This investigation encompasses multidisciplinary research that relates the results of surface exams (infrared reflectography, standard light photography and infrared photography) with analytical investigations. The surface analysis of Frei Carlos’ underdrawings by infrared reflectography has shown heterogeneous work, revealing two different situations: (1) an abundant and expressive underdrawing, revealing a Flemish influence and (2) a simple and outlined underdrawing. This preliminary research raised an important question related to this Portuguese-Flemish workshop and to the analytical approach: Is the underdrawing's heterogeneity, as observed in the reflectograms, related to different artists or is this rather an effect that is produced due to the use of different materials in the underdrawing's execution? Consequently, if different materials were used, how can we have access to the hidden underdrawings? In order to understand the reasons for this dissemblance, chemical analysis of micro-samples collected in underdrawing areas and representing both situations were carried out by optical microscopy, micro Fourier transform infrared spectroscopy (μ-FTIR), scanning electron microscopy coupled with energy dispersive X-ray spectrometry (SEM-EDX) and micro-Raman spectroscopy (μ-Raman). Taking into account the different possibilities and practical and theoretical limitations of surface and punctual examinations in the study of easel painting underdrawings, the methodology of research was adjusted, sometimes resulting in a re-analysis of experimental results. This research shows the importance of combining multispectral surface exams and chemical analysis in the understanding of the artistic creative processes of 16th century easel paintings.

Rock paintings and microorganisms: a new insight on Escoural cave

European cave art is of tremendous importance to understand the cultural traditions of the Upper Palaeolithic (35 000 – 10 000 BP) populations. Indeed, Prehistoric communities performed numerous cave paintings all over Western Europe. Understanding these artworks should provide a better knowledge of these early cultural aspects. Although numerous studies have been carried out to analyse the materials used by those communities, nothing has been done on the techniques’ palette of Escoural Cave’s representations. The present work aims at providing the very first data about the techniques and materials used by the Prehistoric to perform the cave paintings of Escoural (Alentejo, Portugal), and the microorganisms possibly endangering this unique parietal art. In situ observations coupled with an extensive micro-sampling and micro-destructive analyses allowed to characterize the coloured material and the way they were applied on the walls of the cave. Both red and black pigments present major composition’s disparities among the different paintings and drawings, supporting a more complex occupations’ chronology than what was earlier thought. The Palaeolithic paintings have suffered deterioration from environmental conditions and include chemical, mechanical and aesthetic alterations, possibly as a result of fungal activity. The standard techniques for biological assessments used in these contexts provided important insights on the diversity of the microbial population, though they have accuracy limitations. To understand the extent and viability of the existing microbiota, DNA quantification and biomarkers analyses, such as desidrogenase activity were performed and correlated with ergosterol amounts; RESUMO: A Arte Rupestre Europeia é de grande importância para compreender as tradições culturais da população do Paleolítico Superior (35 000 - 10 000 BP). De fato, as comunidades Pré-históricas realizaram inúmeras pinturas rupestres em toda a Europa Ocidental, sendo crucial compreender estas obras de forma a proporcionar um melhor conhecimento destes ancestrais aspectos culturais. Embora vários estudos tenham sido realizados para analisar os materiais utilizados por estas comunidades, nada foi efetuado sobre a técnica de execução das representações presentes na Gruta do Escoural. O presente trabalho visa fornecer os primeiros dados sobre as técnicas e materiais utilizados na Pré-História para executar as pinturas rupestres de Escoural (Alentejo, Portugal) bem como caracterização dos microorganismos possivelmente associados aos danos deste bem único. Observações in situ, juntamente com uma extensa micro-amostragem e análises micro-destrutivas permitiu caracterizar os pigmentos utilizados e a forma como eles foram aplicados nas paredes da caverna. Tanto os pigmentos vermelhos como os pretos apresentam composição distinta nas diversas pinturas e desenhos aí representados, apoiando a presença de diferentes ocupações contrariamente ao que se pensava até então. As pinturas Paleolíticas têm sofrido deterioração, devido às condições ambientais, nomeadamente alterações químicas, mecânicas e, possivelmente como resultado da atividade fúngica. As técnicas usualmente utilizadas para a avaliação de contaminação biológica fornecem informação importante sobre a diversidade da população microbiana, embora apresentem algumas limitações. Para entender a extensão e a viabilidade da microbiota existente, a quantificação de DNA e análise de biomarcadores como actividade de desidrogenases foram realizadas e correlacionadas com o conteúdo em ergosterol.
