Palace lanterns were important and highly visible decorations in the imperial palace in Beijing, China, during the Qing dynasty (1636–1912). Most lanterns had colourful tassels made of fibres. The study performed a comprehensive investigation of the materials and dyes used for palace lantern tassels preserved in The Palace Museum, Beijing. Eight samples with different colours, including yellow, green and red, from five palace lanterns were analysed. By using ultra-performance liquid chromatography combined with time-of-flight mass spectrometry, the compositions of the dyes were identified quickly, and thus the dyes' origins were explored. A X-ray fluorescence spectrometer assisted in the detection of whether a mordant was used during the dyeing process. As a result, the tassels were all made of silk, discovered through the use of microscopic observation and micro-Fourier transform infrared spectrometry analysis. Different dyeing techniques were found in these tassels: yellow tassels were dyed by cork tree or turmeric by a direct dyeing method; greens were dyed by pagoda bud with an iron mordant, or by the combination of cork tree and indigo using multi-dyeing method; and red tassels were coloured with different acid red industrial dyes. These results provide valuable data for the conservation of ancient textile tassels and contribute to the investigation of other hanging tags. 相似文献
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
Lei, Q.P., September .2015. New ontogenetic information on Duyunaspis duyunensis Zhang & Qian in Zhou et al., 1977 (Trilobita, Corynexochida) from the Cambrian and its possible sexual dimorphism. Alcheringa 40, XXX–XXX. ISSN 0311-5518.
The hypostomal condition and the complete ontogenetic development of Duyunaspis duyunensis Zhang & Qian in Zhou et al., 1977 are restudied on the basis of abundant specimens from the Balang Formation (Cambrian, Qiandongian) in Zila Village, Paiwu Township, Huayuan County, Hunan Province. The relatively complete ontogenetic series (degree 0 to 9) provides new evidence that the holaspis of this species has nine rather than seven thoracic segments as proposed by McNamara et al. (2006). Comparisons between Duyunaspis duyunensis and two associated species, Arthricocephalus chauveaui and Changaspis elongata, support its placement in the Subfamily Oryctocarinae. Moreover, based on observations of a large number of specimens, the presence of an anterior indentation on the pygidial end is possibly representative of sexual dimorphism.

This paper rethinks the relationships between capitalist development in indigenous places and the fabric of local differences and specificities. It first develops a critical appraisal of the celebration of ethnic identities, local agency and indigenous knowledge in existing literatures. It suggests that, based on such insights, we can further envision the possibility of questioning and problematising the ontology and concept of the capitalist economy. Above all, this paper is interested in non-capitalist factors percolating into capitalist economies and creating fissures in their logical and ontological coherence. It examines how capitalist economies depend on local specificities to achieve particular configurations. We elucidate this argument with a case study of indigenous development in Lugu Lake, Southwest China, which is inhabited by the ethnic Mosuo people. Through the dual lenses of land and labour, we pay special attention to the transition from grassroots development initiatives to heavy dependence on exogenous capital and entrepreneurs. 相似文献
Cultural resources are today the object of considerable attention in regional economics. Ground for new forms of innovation these resources have given rise to numerous works aiming at understanding the emergence and organisation of culture based economic activities and at identifying the role of these activities in regional development and urban planning. The objective of this article is to explore the way in which resources, and in particular cultural resources, are incorporated into production processes on the one hand, and the consequences on the resources of doing so on the other hand. Becoming an economic resource, a cultural “object” (symbol, image, cultural heritage, traditional know-how, etc.) becomes embedded within commercial relationships. The question we address here is what are the causes and consequences of this commodification of culture for the production systems, the customers and for the local communities which put a certain number of their constitutive elements into play. 相似文献
