Letters exchanged between immigrants and their relatives who remained ‘at home’ are recognised as a valuable resource for exploring identities and emotions in the formation of settler societies. This article departs from this cultural approach to focus instead on the materiality and mobility of the letters as ‘analogue’ sources of knowledge suitable for digitisation, and what this means for histories of place. Our case study traces the movement of an emigrant’s correspondence from Newcastle, Australia to Duffus, Scotland between 1914 and 1924, the subsequent return of these letters and their enclosures to Newcastle and our decision to request digitisation of the items. We show that while traditional archival practice necessarily alienated collections of letters from either their point of origin or their destination, digitisation has the potential to reconnect geographically distant but entangled worlds. 相似文献

ABSTRACTThe protection of cultural heritage against earthquake induced actions is one of the main challenges the earthquake engineering science and practice are facing. This article presents a seismic assessment study on one of the most ancient colonial buildings present in Peru, the Cathedral of Lima, focusing on its towers. A historical review highlighted how these structures, together with the whole Cathedral, suffered intense damage and partial collapse during previous earthquakes. In order to identify the structure main deficiencies, both linear kinematic analyses and nonlinear static analyses have been performed. Different nonlinear finite element models have been created to evaluate the influence of the adjacent walls. Different load distributions have been compared to evaluate how simplified patterns could provide results close to load distributions taken from a modal analysis of the complex. A simple retrofit strategy, consisting on the introduction of steel ties, has also been studied as a reference. Results show good correlation between kinematic and pushover analyses. The construction, when compared to the requirements of the national code for new buildings, results significantly vulnerable, pointing out the need to accept some structural damage even after seismic retrofit. 相似文献

We report on energy-dispersive X-ray fluorescence (EDXRF) sourcing of 807 basalt artifacts and 34 basalt ecofacts recovered from stratified midden at Nu‘alolo Kai, Kaua‘i. These data are compared with EDXRF analyses of 473 alluvial pebbles from Waimea Canyon, 34 adzes from the Kaua‘i Museum, and published geochemical data for Kaua‘i basalts. Formal tools, such as adzes, chisels, and mirrors were predominantly manufactured from sources not available at Nu‘alolo Kai. Most adzes and chisels are consistent with sources available elsewhere on Kaua‘i, but two basalt mirrors are outside the expected geochemical range of Kaua‘i basalts. In contrast, almost all expedient tools were manufactured from basalts available at Nu‘alolo Kai. These findings support the existence of an island-wide distribution system for adze material on Kaua‘i, and challenges extant models of pre-contact Hawaiian economics to consider the mechanisms through which specialized commodities were produced and distributed. 相似文献

ABSTRACTThe design of metallic structures in the 19th century is a subject topic of much admiration, as many emblematic structures that are currently withstanding the test of time have become part of our built cultural heritage. Knowledge on the assumptions and design procedures available at that time is of importance to structural engineering nowadays. It allows for the understanding, maintaining and safe extending of the service life of historical metallic structures. The goal of this article is to describe the evolution in the design and calculation of metallic structures during the second half of the 19th century, with focus on Western and Central Europe. Special attention is paid to the similarities and differences between the 19th century design rules and the current structural design standards. Based on a literature survey, the evolution in terms of load definition, calculation methods, material properties, and verifications are described. Different design aspects are illustrated through a case study: The Garabit viaduct in France. 相似文献

This experiment assessed whether consolidation of cremated remains facilitated cross‐sectioning and grinding, which often are required for microstructural analyses such as the histomorphometric estimation of age and the examination of pathological lesions. Green, bovine femoral diaphyses were cremated at three temperature ranges (346–357°C; 610–755°C; 684–838°C) in an electric furnace and then consolidated with Acryloid B‐72 or Butvar B‐98 using simple brushing and immersion techniques. After consolidation was complete, bone pieces were cross‐sectioned and ground to a thickness of 100–120 μm. Results indicate that specimens treated with Acryloid B‐72 are harder and stronger than Butvar treated and untreated control specimens. Acryloid B‐72 is, therefore, recommended for the consolidation of cremated remains in preparation for microstructural analysis. Copyright © 2004 John Wiley & Sons, Ltd. 相似文献

Ion beam induced luminescence (IBIL) was applied, along with cathodoluminescence (CL), on seven samples of marbles of historic and architectural interest. The CL colours, observed in a cold cathode device, have been related to the IBIL spectra. Moreover, a detailed analysis of the IBIL spectral features has made it possible to disclose the influence of the chemical composition and to emphasize the crystal‐chemical role of the Mn2+. Beyond the chemical information and the crystal‐chemical interpretation, the spectra are recognized as being valuable in the field of archaeological studies for their significance as fingerprints of marbles, giving information on their nature and origin. 相似文献
