Mineralogical Phase

ABSTRACTThe monastery of St. John in Müstair, a UNESCO world heritage site, preserves archaeological remains and stone structures dated from the 8th century to the present. It has been extensively studied archaeologically so that numerous samples of historical materials, including mortar, are available for study. In addition to that, some of the structures have been precisely dated with dendrochronology. The monastery is located in a region characterized by dolomite rocks and the mortars are therefore of dolomitic nature, being perfectly suited to test the possibility of being dated with 14C. Furthermore, the presence of embedded carbon fragments has provided additional independent data to support or deny the results of mortar dating. A comparison of the results obtained from radiocarbon (14C) dating of bulk mortars, sieved fractions enriched in binder, lime lumps and carbon fragments, for two samples is presented, in relation to the petrographic characterization and the mineralogical phase content. This preliminary study shows that the dating of 14C can potentially be applied to the mortar of Müstair, as results in accordance with the established chronologies have been obtained for one sample. However, if the dolomitic sand contamination is very high, further studies are needed to develop a specific sample preparation technique.

First Results

The Roman and Byzantine port of Butrint, situated on the SW coast of Albania directly opposite the island of Corfu, has been the focus of a major research project since 1994. The investigation of the site and its hinterland commenced with excavations within the walled town and a survey of sites and monuments in the region (Hodges et al 1997). Despite a brief hiatus caused by civil unrest in Albania in 1997, work continued with excavation and study seasons in 1998 and 1999. The results of the first five years of the project are due to be published shortly (Hodges, Bowden and Lako, forthcoming).The second phase of the Butrint project, starting in 2000, has encompassed a wide variety of research aims. They have included extensive research on the archives of the Italian mission that conducted large-scale excavations between 1928 and 1942. Among other finds, this resulted in the discovery of the manuscript of L. Ugolini's Albania antica vol. 4, the hitherto unpublished results of the Italian excavation of the Hellenistic and Roman theatre (Gilkes, forthcoming). Other archival research has focussed on the records of the communist-period archaeological investigations, and has resulted in a much better understanding of the aims and results of these projects, which in some cases are almost wholly unpublished. Our project is also concerned with the controlled development of the site for tourism. This has resulted in the expansion of the UNESCO World Heritage site to 2900 ha and the creation of a National Park with the intent of protecting the archaeological and natural landscape around Butrint (Hodges and Martin 2000; Martin 2001). The present report is a synthesis of the first results of the major excavations of 2000 and 2001. While it is possible (and indeed likely) that interpretations may change as excavations continue, it was felt that the material was of sufficient interest to justify an interim statement.

This research presents the value of historic urban landscape (HUL) elements in influencing the character of George Town UNESCO World Heritage Site (WHS), Penang, Malaysia. The values were perceived by the local community of different social-cultural groups that occupied the study area. The historic urban landscape elements constitute towards the protection of its townscape. The identification of the heritage elements influenced by the community interaction with their environment. This study also helps to define the character of a place, as well as reflecting its historical significance. The study adopted four techniques to gather both qualitative and quantitative data, including questionnaire survey, in-depth interview, visual survey and content analysis. In general, the local community has the capability in valuing the historic urban landscape values. The outcomes of their perceptions became the statement of the historic urban landscape values, which are expected to lead to the development of the areas. The community evaluation and perception can be expanded in implementing any development of the historic urban area by the authority.

Significant Difference

The Wadden Sea ecosystem is unique in many respects from a biological perspective. This is one reason why it is protected by national parks in Germany and by its designation as a UNESCO World Heritage Site. In biology didactics, there are only a few studies that focus on the Wadden Sea. This work investigates students’ word associations with the two stimulus words “national park” and “UNESCO World Heritage Site”. The survey was conducted among students living directly at the Wadden Sea and among students from the inland. The analysis of the identified associations (n = 8345) was carried out within the framework of a quantitative content analysis to be able to present and discuss the results on a group level. A statistically significant difference was found between the two groups. Overall, results showed that the students made subject-related associations as well as a large number of associations to both stimulus words that could be judged as non-subject-related. In some cases, a connection with the region of residence could be found, but this was not generally the case. Even students’ immediate residential proximity to the Wadden Sea is no guarantee that they have knowledge of the two considered protection terms.

Explicit Dynamic

Historic monuments and construction capture the knowledge of civilizations of the past and are a source of pride for people of the present. Over the centuries, these buildings have been at risk from natural and man-made causes. The Alhambra, a UNESCO World Heritage Site in Granada, Spain, is one of such places. This paper aims to evaluate the structural performance of the Torre de la Vela, a tower in the Alhambra, under blast loads. The loads were based on historical records of barrels of gunpowder and were modeled as simplified pressure profiles using existing empirical equations. The effect of impulsive loading on the material properties was accounted for using dynamic increase factors, determined experimentally by previous authors. The model was created using finite element methods (FEM) and the problem was solved using explicit dynamic analysis available in Abaqus/Explicit. Using the failure volume damage index, a blast load applied outside and inside of the building would create a low damage level, which should be treated with caution given the occurrence of localized damage. The removal of elements exceeding a given damage threshold led to more visible damage patterns than the Concrete Tension Damage option in Abaqus.
