Kuwait–Georgian archaeological work at Failaka Island showed the need for geological study. Analysis of sediments related to drinking water-collecting cisterns was performed on a Late Islamic settlement (NE part of the island) in 2018. Field sedimentological, grain size and XRD analysis of the sediment profiles showed that the shallow (about 1 m deep) cone-shaped wells are dug in the loose, porous, cross-stratified calcareous coarse-grained quartz sandstones. Three upper layers of quartz sandstones in the profile have high infiltration rate and provide a rare yet ideal material for water retention. The fourth dense layer below, composed of very fine sand and silt fraction, tends to hinder water movement and forms a relatively impermeable water-resistant surface. Thus, the distribution patterns of clay content, grain sizes and porosity of the well-hosting sediments are favourable for freshwater infiltration and harvesting. An additional petrographic analysis was conducted on different types of rocks discovered on the archaeological site, used as building material and fragments of stone artifacts to identify their origin. It was established that archaeological building material is of local origin, whereas the source rocks for stone artifacts were imported.  相似文献

Cultural resource management (CRM) work accounts for most of the archaeology conducted in the United States. A diverse and somewhat fragmented field, CRM has nonetheless achieved a degree of institutional and organizational maturity. CRM archaeology has produced important contributions to archaeological methodology and has established and refined knowledge of regional cultural-historical sequences and settlement and subsistence patterns. The current florescence of historical archaeology is attributable to CRM. Yet the maintenance of high quality in CRM is a pervasive and enduring problem. Academic institutions need to reestablish alliances with the CRM community. The future viability of CRM archaeology depends on factors both internal and external to the discipline: regulatory and statutory “reform,” agency funding levels, looting and other destructive forces, and Native American and other public involvement.  相似文献

In Latin America, ethnicity is equated with indigenity. It is an objective of this article to review the legacy of Anthony Smith regarding the vitality of the ethnic past and the myth of origin, as the core of his theory of nationalism based on the weight of ethnocentrism. To this end, we address two routes, the use of the ethnic past and ethnicity by nationalists and founders of the state and, how indigenous intellectuals, on the other, have found a reinvention of their identities through various myths of Amerindian origin. Ethnic myths and the use of the ethnic past have been accepted, denied or rejected by nationalists, while indigenous peoples adhere to their own myths or seek to reinvent them. Mythical information is a component of identity but also requires institutions to disseminate such information among the group.  相似文献

In Chinese traditional timber buildings, stitching is very common. When the bearing capacity or the rigidity is inadequate, a timber beam is often strengthened with another beam using the stitching method. The timber stitching beams are mainly of two types—the small-top/big-bottom type and the big-top/small-bottom type. To study the bending behavior of these two types of timber stitching beams, including the failure mode, the flexural capacity, the strain distribution at mid-span section, and the maximum deflection, bending tests are carried out on 14 timber stitching beams with Chinese traditional conformation for seven pine beams and seven fir beams. The results show that the failure modes of the small-top/big-bottom type of stitching beams all show brittle fractures at the bottoms of the bottom beams. The failure modes of the big-top/small-bottom type of stitching beams all show brittle fractures at the bottoms of the top beams. The distribution of section strain along the height of each part of the beam basically obeys plane hypothesis. Based on the theoretical and experimental analysis, the calculation formulas of flexural capacity and maximum deflection of these two types of timber stitching beams made of pine and fir are presented.  相似文献

Architecture in early modern Sardinia is characterized by a strong continuity with previous practices. In the second half of the 16th century, new models join the Gothic building tradition, linked in particular to trends in military engineering and Classicism of the Catholic Counter-Reformation. The Jesuit church in Sassari offers an interesting example of the intertwining of these architectural modes, which originated with a sudden change of leadership at the site. Giovan Maria Bernardoni, an Italian Jesuit architect, initially modeled the church after the Gesù in Rome, and it was partially built under his direction. After his departure from Sardinia, local master builders finished the construction, following the Gothic tradition and possibly some external influences. This article analyzes the church, particularly focusing on the challenges presented by its articulated vaulting system completed between 1587 and 1609.  相似文献

Excavations in the arid regions of Egypt provide insight into the many types and uses of mudbrick architecture. Upon exposure the inherently unstable building material decays rapidly, resulting in severe loss or complete destruction of once well-preserved buildings. The preservation of mudbrick structures is relatively complicated and expensive. Research has focused on the circumstances that enable preservation and the influence of climate and weather over time. Conservation treatments should address these two processes as soon as possible after exposure of the structures. Our assessment of a range of conservation methods leads to the conclusion that reburial is among the least objectionable method of preservation, despite its drawback of returning the excavated buildings to a situation where they are invisible to both researchers and the public.  相似文献

Are post‐Ottoman nation‐building policies in the Balkans a legacy of the millet system? Some contend that the discriminatory nation‐building policies along religious lines employed by Balkan nations ruling elites are a legacy of the Ottoman era millet system (administration by religious affiliation); others argue that the Ottoman legacy is palpable in the millet‐like features preserved in the minority rights protection system resulting from World War I, and yet other scholars see the millet system as a critical antecedent. Studying closely the policies towards non‐core groups in the post‐Ottoman Balkans, one finds that the ‘Ottoman legacy’ is much more differentiated than is commonly assumed and that effects vary widely from place to place. Moreover, I argue that the persistence of certain features from one period to another may be an actual legacy in some cases, but there is also a possibility that we are dealing with a manufactured legacy, where elites choose to intervene and perpetuate an institution or a particular feature of it. I empirically demonstrate this distinction in a crucial case using archival sources.  相似文献

Recent research has studied the effects of seasonal variability on waterlogged burial environments. In a new approach to the study of archaeological contexts, the use of controlled laboratory conditions via lysimeters has enabled new insights into the nature of short term fluctuations in saturation, and the impact that these can have on burial contexts. In addition, the protocols used have facilitated interesting insights into burial environments and the way in which fluctuations in saturation and seasonality can impact on the contained organic components within them.  相似文献

新时期我国法制建设的历史进程与基本经验   总被引:1,自引:0,他引:1  
以1982年宪法的公布实施和1997年依法治国基本方略的确立为标志,新时期我国法制建设的历史进程可分为三个阶段:从1978年到1982年为恢复阶段;从1982年到1997年为全面发展阶段;1997年以来为全新发展阶段。新时期我国法制建设的基本经验主要有:必须正确处理党的领导与法制建设的关系;必须正确处理法制建设与经济建设的关系;必须把民主建设与法制建设结合起来;必须把立足中国国情与借鉴外国经验结合起来;必须不断完善法律监督体系。  相似文献
