Ancient mortars played a crucial role in the construction of historical architectures due to their physical and chemical compatibility with traditional building materials such as stones and bricks. Therefore, the analysis and optimization of the ancient mortar formula are significant in the restoration and preservation of historical sites. In this work, 20 mortar samples selected from five ancient stone pagodas in Zhejiang Province, China, were analyzed. The results showed that mud, lime-soil mortar, lime-sand mortar, and lime-gypsum mortar were used as binders in these pagodas. The Ca(OH)2/aggregate ratio ranging from 0.3 to 2.7 was usually used to prepare lime mortar. Protein and polysaccharide were also found in some samples. 相似文献

The reemergence of cognitive studies in comparative psychology and ethology, coupled with ongoing archaeological discoveries and recent advances in genomics, have contributed to the current explosion of scientific interest in dogs (Canis lupus familiaris). The long and complex evolution of a human-dog relationship is explored from the differing perspectives of ethology, cognitive sciences, evolutionary anthropology, archaeology, and paleoanthropology. Our understanding of dogs is again shedding light on human cognitive evolution and the complex, and at times controversial, process of domestication. 相似文献

Seal on Land, Elk at Sea: Notes on and Applications of the Ritual Landscape at the Seaboard 总被引:1,自引:1,他引:0
Ritual landscapes at sea are marked in the cognitive world of coastal people by a primary antagonism between sea and land. This contrast is negotiated by liminal 'foreign' agents, selected for their symbolic adherence to either part. The primary source of maritime culture is fishing as a survival of past hunter-gatherer societies. Forms of religious or magical management of this contrast are manifold, from recent superstitious magic to powerful symbols in ancient worship, objects, art, architecture and cult. Also described are ways of using the sea on land as a magic metaphor and a fundamental point of reference. Related dichotomies and ways of negotiating them, such as the liminal agent, exist elsewhere in the cognitive world of pre-industrial societies, so these ideas could have applications in archaeology.

Archaeobotanical and GIS-based approaches to prehistoric agriculture in the upper Ying valley,Henan, China 总被引:3,自引:0,他引:3
Archaeobotanical survey has sampled a series of late Neolithic to early Bronze Age settlements in the upper Ying valley (part of the central plain of China) and provided useful data for understanding prehistoric arable ecology and farming during a period of increasing local social complexity. A combination of the modelling functions offered by Geographic Information Systems (GIS) and the data reduction possibilities offered by Principal Component Analysis (PCA) allow us to explore possible relationships between local arable ecology, crop-processing strategies and the natural environment. The results should be treated cautiously given the size of the analytical sample but suggest that differences in the natural environment around each site may explain varying patterns of wild food collection, while social and cultural factors may better explain variation in farming practice and crop-processing at different sites. 相似文献

Abstract In view of the compendium of field evidence and supporting analysis work indicating the possible damaging effects of vertical earthquake ground motion, this paper addresses the problem of code-type vertical force calculation. In light of recent engineering seismology studies of the relationship between vertical and horizontal peak ground acceleration, the inadequacy of the 2/3-rule depicted by codes is highlighted. A simple piece-wise linear relationship is proposed and shown to represent existing strong-motion measurements adequately. Bilinear and inelastic spectra are derived and studied. It is demonstrated that net tensile forces and displacements may ensue, thus eroding the shear resistance of RC columns. A simple procedure is outlined whereby modal analysis may be employed to estimate conservatively vertical earthquake forces on buildings. Finally, areas of further exploration and refinement are identified. 相似文献

This review describes four disparate books that relate to the anthropology of religion. Each has a distinctive approach, ranges over a wide subject matter, and makes provocative claims. In summarizing and critiquing them most attention is paid to their perspectives on the natural and the supernatural. This leads to consideration of related work in the anthropology of extraordinary experience. It is argued that while our different approaches to the supernatural may reflect deep epistemological divisions within anthropology and, more broadly, in society, a form of semiotics that takes emergent complexity into consideration does provide opportunities for consensus. 相似文献
