The Royal Artillery Factory of Seville in Spain originated from pre‐existing private bronze foundries dating from the 16th century. The paper analyses the stratigraphy of wall cladding in the areas traditionally known as the ‘Old Foundry’ and the ‘New Foundry’, through its characterization by optical microscopy, scanning electron microscopy with energy‐dispersive X‐ray spectrometry (SEM‐EDX), micro‐X‐ray fluorescence (μ‐XRF) and micro‐X‐ray diffraction (μ‐XRD), in order to analyse the metal deposits that have accumulated since the 17th century. The data obtained allowed the verification of the available historiographical information and the location of the original bronze smelting furnaces. The analysis of patinas deposited on the overlapping layers of lime also confirmed that neither the raw materials nor the composition of the alloys used presented any substantial changes.  相似文献

Relying on stochastic frontier analysis we propose a methodology to study the technological characteristics and cost efficiency levels related to the provision of public infrastructure for basic utilities. The methodology assumes a cost minimizing behaviour on the part of public officials when planning the construction of local infrastructure, which is represented by way of a flexible translog cost function. Introducing relevant definitions of scale economies, associated with larger numbers of inhabitants and dwellings, as well as economies of density, brought about by reductions in urban dispersion, we analytically determine the optimal population densities for which average cost is minimized. We illustrate our model with the water cycle sector, including water distribution, sewage collection and cleansing of wastewater, and considering data at the municipality level for the Spanish region of Castilla y León. The obtained results indicate potential cost savings in the form of decreasing average costs, as relevant scale and density economies are present, along with large inefficiency levels. Relevant policy guidelines favouring larger and denser urban sizes are drawn, as the observed cost excess is the result of a general suboptimal urban size in terms of population density, and the negative effects of dispersed settlement patterns.  相似文献

Bones treated at low temperature do not present major modifications although, macroscopically, boiled bones may be distinguished from unboiled ones as they are smoother, lighter and more transparent. Such observations should correspond to textural modifications at a nanometric level and should depend on boiling time. In this study, contemporary human bones, boiled during various time intervals, were characterized using scanning electron microscopy (SEM), energy dispersive X-ray spectroscopy (EDS), X-ray diffraction (XRD) and nitrogen adsorption (BET). The results were used to estimate the boiling time in four archaeological samples (Neolithic bones from Malalmuerzo cave, Spain). It is concluded, comparing Neolithic bones to contemporary ones and from the textural characterization at a nanometrical level, that two of the archaeological bones were boiled and that they were boiled for less than 6 hours.  相似文献

The presence of processed birds in the archeological faunal record is considered key to assessing human dietary evolution. Taphonomic studies on birds from sites older than Marine Isotope Stage (MIS) 2 have become relevant in the last few years, leading to the proposal of more complex scenarios of human subsistence. Several works have demonstrated direct evidence of bird consumption by Homo prior to anatomically modern humans in Europe; however, others support the hypothesis of non-anthropogenic bird accumulations. This has led to the necessity of determining what elements or factors cause the human exploitation of birds in some archeological sites before the end of the Pleistocene. The Grotte des Barasses II site is located within this framework. Short-term human occupations have been attested by the presence of lithic tools and processed macrofaunal remains. Additionally, a small assemblage of bird bones has also been recovered. Here, we present a detailed taphonomic study with the aim of exploring possible relationships between these avian taxa and human occupations. Despite the fact that Neanderthals inhabited the cave, avian specimens show damage pointing to different causative agents. Direct evidence (digestion, gnawing) indicates that mammalian carnivores and nocturnal raptors were mainly involved in the accumulation of bird bones. We propose some factors that might determine whether or not small game was exploited in this specific locality and emphasize the importance of such analytical approaches in the general interpretations of the Pleistocene sites.  相似文献

The aim of this article is to offer a new interpretation of the role of women in the Catholic movement in 1920s Spain. It responds to historical analyses that view this mobilisation as the product of clerical manipulation and that consider its feminist aspects to be flawed. The new interpretation presented here is based on a notion of citizenship understood as both a process and as a form of identity construction, and which was configured historically as a result of the incorporation of modern ideas of women, the nation and religion. As a result, this analysis examines the relationship between Catholicism and modernity in greater complexity than the dichotomous views frequently encountered in Spanish historiography.  相似文献

The differences between boiled or unboiled bones are not often studied. However, they are crucial to understand postmortem rituals and to establish defleshing procedures and mortuary practices. In this work, human bones boiled in sea or fresh water are characterized. The bone composition, as well as the compounds present in the resulting materials, shows that salt alters the boiling process mechanism. Hence, from structural and morphological criteria, it is possible to distinguish if a bone has been boiled in salt or fresh water. In both sets of samples, the smoothness of the bone surface depends on boiling time, but only in bones boiled in seawater, filaments are observed apparently pouring out of the pores.Those differences which are mainly morphological (smoothness of the surface) are explained in terms of a collagen diffusional mechanism favored by sodium and chloride ions. For a boiling time of 6 h, the surface is covered by a thick layer or crusts of degraded collagen. Experiments with seawater may be used as model experiments to simulate taphonomical alterations in bones exposed to salt water.  相似文献

Many Pleistocene caves and rock shelters contain evidence of carnivore and human activities. For this reason, it is common to recover at these sites faunal remains left by both biological agents. In order to explain the role that carnivores play at the archaeological sites it is necessary to analyse several elements, such as the taxonomical and skeletal representation, the age profiles, the ratio of NISP to MNI, the anthropogenic processing marks on the carcasses (location and purpose of cutmarks and burning and bone breakage patterns), carnivore damage (digested bones, location and frequencies of toothmarks and bone breakage), length of the long bones, frequencies of coprolites and vertical distribution of the faunal remains, inter alia. From this, the documentation of carnivores in a faunal assemblage with a clear anthropogenic component can be understood from three main phenomena: (1) the carnivores as accumulators and the use of the site as a den; (2) carnivores as scavengers of hominid refuse and; (3) carnivores as hominids’ prey. Of these three phenomena, the last one is the least documented at the Middle Pleistocene sites. From this perspective, here we present the case of the anthropogenic use of a lion (Panthera leo fossilis) from level TD10-1 of Gran Dolina (MIS 9, Sierra de Atapuerca, Burgos, Spain). The lion bone remains show signs of direct interaction between this big cat and human groups that occupied Gran Dolina in these chronologies. From this perspective, the aim of this paper is to contribute to the knowledge of the role developed by large carnivores in the anthropogenic contexts and to provide data on human use of these predators at the European Middle Pleistocene sites.  相似文献

This paper puts into question the conventional way of delineating tourism destination borders in terms of taken-for-granted administrative boundaries. Despite the fact that the literature on destination boundaries advocates for conceptual frameworks where customers’ consumption patterns play a more fundamental role, instances of actual attempts of structuring tourism geographies into ‘new tourism areas’ are scant, and instances of zoning on the basis of visitors’ consumption patterns are absent. A method for identifying alternative and more effective consumption-based tourism zones that combines geographical information system and hierarchical cluster analysis techniques, and that relies on time distances between attractions, is thus proposed, and implemented in the case of the Pyrenees mountain region. As a result the region is restructured into nine new tourism zones, which, compared to the original destinations, are more uniform in size and have a higher correlation index between attractiveness and accommodation intensity; they also have different levels of cross-border intensity and are very similar to historical regions; and the more they differ from the original destinations the higher their attractiveness, which supports the effectiveness of the new zoning technique. Four types of tourism zones ranging from higher to lower tourism intensity are also identified.  相似文献

The fat‐ and nutrient‐rich marrow of animal bones can be extracted using different techniques. Passive hammerstone percussion has been the primary focus of experimental bone breaking and the main analogy to understand archaeological bone breakage. Here, the term ‘passive’ is applied because the bone to be broken passively receives the impact from a hammerstone. In addition to this technique, there is another bone‐breaking method that also requires direct percussion, but in an active way. This method is percussion by ‘batting’, in which the bone is actively hit against an anvil until the bone breaks. This technique has rarely been considered at an experimental level and, therefore, has been omitted in the majority of the archaeological interpretations of faunal assemblages with pre‐use of fire technologies. In this study, we attempt to analytically characterize this type of bone‐breaking technique through a systematic comparison with hammerstone percussion. The applied statistical tests will allow us to distinguish some diagnostic modifications, such as the outlines of the fracture planes and the type of notches or their location with respect to the longitudinal axis of the bone. These features and their proportions allow the consideration of the use of this technique in Pleistocene anthropogenic faunal assemblages.  相似文献
