O mundo rural e o território de Évora durante a Antiguidade Tardia

Neste estudo pretende-se realizar uma análise da cidade de Évora e do seu mundo rural durante a Antiguidade Tardia. Através de estruturas funerárias e religiosas, e de alguns elementos arquitectónicos, pretendemos contribuir para o aumento de conhecimento da cidade de Évora e do seu território. Ao longo deste estudo irá realizar-se uma análise do cristianismo, dos mártires, dos concílios peninsulares, da cidade durante a época em estudo, da ascensão da Igreja e das aristocracias locais, do mundo rural e das estruturas funerárias e religiosas; Abstract: The Rural World and the Territory of Évora during Late Antiquity In this study it is pretended an analysis of the city of Évora and its rural world during Late Antiquity. Through funerary and religious structures, and some architectonic elements, we pretend to contribute for the augmentation of knowledge of the city of Évora and its territory. Thought this study it’s going to be done an analysis of Christianity, martyrs, the peninsular councils, the city during the studied epoch, the ascension of the Church and the local aristocracies, the rural world and the funerary and religious structures.

A new look into the archaeological materials from the Museum of Évora, Portugal – the case study of the Zambujeiro Dolmen

This paper presents the results of a multidisciplinary and multi-analytical study of the amber beads, red pigments, lithic arrowheads and selected ceramics from the Museum of Évora’s collection of the Zambujeiro Dolmen. Amber beads were studied by Attenuated Total Reflectance Fourier Transformed Infrared Spectroscopy (ATR-FTIR) and Pyrolysis coupled to Gas Chromatography and Mass Spectrometry (Py-GC/MS) to confirm their chemical nature and provenance. The red pigments, frequently found in funerary Neolithic context of the Iberian Peninsula, were studied with micro-Raman, and Scanning Electron Microscopy coupled to Energy Dispersive X-Ray Spectroscopy (SEM-EDS) to identify their chemical nature and provenance. The lithic arrowheads were analysed by portable X-Ray Fluorescence (p-XRF), micro X-Ray Diffraction (XRD), SEM-EDS, and Laser Ablation Inductively Coupled Plasma Mass Spectrometry (LA-ICP-MS). The ceramic materials were studied to infer provenance and production technology by p-XRF, XRD and SEM-EDS; ceramic contents were evaluated by GC/MS. The studies have shown that while some materials travel hundreds or thousands of kilometres to arrive to the Zambujeiro Dolmen, local materials were also used in the items selected by the communities to honour their deceased.

Toxicological assessment of novel green biocides for cultural heritage.

The damaging of buildings and monuments by biological contamination is a cause of serious concern. Biocides based on chemical toxic compounds have been used to mitigate this problem. However, in the past decade many of the most effective biocides have been banned due to their environmental and health hazards. Therefore, proper remediation actions for microbiologically contaminated historic materials based on environmentally safe solution is of vital importance. Bacillus species are emerging as a promising alternative for built heritage treatment. They produce a great diversity of secondary metabolites with biological activity, well known to possess antagonistic activities against many fungal pathogens. In order to evaluate the antifungal activity of the novel biocides produced in our laboratory by cultures of selected bacterial strains, liquid interaction assays using four biodeteriogenic fungi were achieved, revealing a nearly 100% of inhibitory capacity to fungal proliferation. To confirm their effective safe toxicological properties, in vivo tests using two different biological models were performed. The lyophilized supernatant of the Bacillus culture broth showed no lethality against brine shrimp and also no toxicological effects in Swiss mice through administration of acute dose of 5000 mg/kg by oral gavage. In fact, the bioactive compounds were no lethal at the tested dose unlike Preventol® (commercial biocide) that induced acute toxicity with 10 times minor concentration dose administrated in the same conditions. Therefore, the new bioactive compounds that suppress growth of biodeteriogenic fungi on historical artworks, presenting at the same time no toxicity against other living organisms, constituting an efficient and green safe solution for biodegradation/biodeterioration treatment of Cultural Heritage.

Yunus: ricerche e scavi nella necropoli dell'età del Ferro di Karkemish

La comprensione del contesto funerario rappresenta per l’archeologo uno degli aspetti più complessi da interpretare della società antica a causa dell’interazione tra numerosi, diversi fattori culturali. È quindi fondamentale condurre un’attenta e accurata analisi che tenga conto di tutti gli aspetti inerenti la sepoltura e il corredo. La riapertura nel 2011 degli scavi sul sito di Karkemish da parte della missione turco-italiana del Dipartimento di Storia Culture Civiltà dell’Alma Mater Studiorum - Università di Bologna, in collaborazione con le Università di Istanbul e Gaziantep, ha reso necessaria una rilettura dei dati di scavo emersi durante le precedenti missioni organizzate dal British Museum, condotte tra il 1913 e il 1914 nella necropoli di Yunus, per metterli in correlazione anche con i dati inediti ottenuti nelle nuove campagne di scavo all’interno del sito di Karkemish e Yunus. Lo scopo finale di questo progetto consiste in una nuova analisi dei contesti funerari databili all’Età del Ferro volta a definire, ove possibile, lo sviluppo sia della necropoli, sia della cultura materiale con l'intenzione di apportare un significativo contributo alla ricostruzione e alla comprensione di una delle più importanti necropoli dell’Età del Ferro
