ABSTRACTHistorical centers are always composed of masonry building aggregates often designed without respecting seismic design criteria. The current seismic Italian code does not foresee a clear calculation method to predict their static nonlinear behavior. For this reason, in this article the seismic response of structural units into masonry aggregates has been predicted through a simplified modeling approach. The implemented procedure has been calibrated on the results of a numerical model performed by using the Equivalent Frame Method (EFM), implemented within a Finite Element Method (FEM) calculation program, used to investigate a basic building compound representative of the constructive techniques developed in the past decades in the Southern Italy.First, the whole aggregate has been modeled and analyzed in the nonlinear static field in order to evaluate the seismic behavior of both intermediate and head structural units.Later on, the seismic response of these structural units, considered as isolated structures, has been assessed by considering in simplified way their position in the aggregate, as well as the influence of other constructions.Finally, the achieved results on the above single analysis cases have been compared with those deriving from the investigation of the whole building compound, allowing to confirm the effectiveness of the proposed novel analysis procedure. 相似文献

This paper proposes an empirical climate classification method based on the application of multivariate statistics. In this method, the technique of supervised and unsupervised image classification is used to classify the data and define climatic units. envi software is used to perform the image classification, specifically, the Iterative Self‐Organizing Data Analysis Technique algorithm. Supervised classification is also applied based on reference variables, fundamental parameters and a classifier. The obtained results display greater objectivity, reliability, operability, accessibility and reproducibility than previous climate classifications devised for the region of Andalusia (Spain), taking into account that these previous classifications were not based on quantitative criteria. 相似文献

This study presents the isotopic ratios, radiocarbon datings, and anthropological analyses of five (N = 5) Early Copper Age individuals from two archaeological sites (Arruzafa and Iglesia Antigua de Alcolea) of the Middle Guadalquivir Valley near the city of Córdoba (Spain). Four had been buried in the same grave, possibly in a single event or in a very short time lapse. The collagen residue analyses of the individuals offer δ13C values ranging between −20.08 and −18.4 and δ15N values between 8.57 and 11.15. The findings indicate that the infant and the elderly had, respectively, the richest and poorest animal protein diets, the first likely as a result of nursing. The combined study of these five individuals offers an interesting approach to a small segment of population of the farming communities occupying this territory at the beginning of the Copper Age (3200–3000 cal BC). 相似文献

This paper discusses the relationship between early anarchism and republican/nationalist ideas. We will focus on the case of British‐based activists grouped around the journal Freedom and their engagement with Irish nationalism during the Age of the Empire. Freedom, founded in 1886, was the most important anarchist journal of the English‐speaking anarchist–communist networks at the time and was the main editorial reference for the worldwide community of anarchist activists, mostly exiled, who resided in London at that time. Extending current interdisciplinary literature on transnational anarchism, we argue that anarchist views of nations, while rejecting the novel notion of the nation‐state, were associated with anti‐colonial struggles and with republican anti‐monarchical and egalitarian notions. Based on primary sources, we discuss the intersections between these Britain‐based anarchists and anti‐colonial Irish radicals, by engaging both with their writings and their international networks of solidarity, thus exploring the complex intermingling of anarchism, anti‐colonialism, and republicanism. 相似文献

This paper puts forward the new analytical framework of ‘Digitally Mediated Iconoclasm’ (DMI) to analyse and interpret iconoclastic acts that are experienced through the propaganda (videos, social media, photographs, and other media) that the actor perpetrating the destruction makes available in global information networks for its consumption, duplication, and distribution. DMI captures three stages of the destruction (before, during and after the event) as both evidence of that destruction and as a perdurable digital archive. To demonstrate the relevance of DMI, we focus on an analysis of the videos and photographs depicting heritage destruction at pre-monotheistic sites targeted by the Islamic State (IS), such as Palmyra in Syria, the Mosul Cultural Museum, Nineveh and Nimrud in Iraq. The analysis focuses on the three stages that DMI comprises, showing the different photographic and audio-visual production techniques that the IS uses to enhance the tension that is built up leading to the destruction of cultural heritage while allocating material and human resources to produce digital propaganda. This analysis demonstrates how the analytical framework of DMI can be used to advance important work in heritage and media studies. 相似文献

The lack of written sources for many of the medieval castles in the northern Apennines (Italy) makes it difficult to completely establish the most ancient historical phases of these settlements. The church of San Michele belongs to an abandoned fortified settlement of the Castle of Benabbio, in the mountains surrounding Lucca. Thanks to an epigraph still visible on the façade, the church foundation is dated back to AD 1218. However, several archaeological findings at the settlement seem to suggest stages of encastlement that are older than the church foundation. 相似文献

The value of strontium isotope analysis in identifying immigrants at numerous archaeological sites and regional areas has been demonstrated by several researchers, usually by comparing 87Sr/86Sr values of human tooth enamel and/or bone with the local strontium isotope signature determined by faunal and environmental samples. This paper examines the feasibility of using 87Sr/86Sr ratios to investigate residential mobility in the Nile Valley region, specifically at the New Kingdom period (∼1050–1400 BC) archaeological site of Tombos (ancient Nubia). Archaeological and textual information regarding this period indicates that immigrant Egyptians and local native Nubians were likely interacting at this site during a period of Egyptian colonial occupation. The results of this study suggest that non-local individuals may be distinguished from locals using 87Sr/86Sr values and that colonial agents in the Tombos population were probably both local native Nubians and immigrants. 相似文献
