This article studies the performance of economic base isolators using tyres filled with elastomeric recycled materials. The research was conducted to analyze base isolators to be used in developing nations, where the application of conventional elastomeric rubber bearings due to economic reasons is limited.The tested isolators are made of kart tyres filled with different recycled elastomeric materials and aggregates. Dynamic and static tests proved acceptable vertical to horizontal stiffness ratio of the bearings and shake table tests showed an excellent enhancement of the base isolated structural response compared to the corresponding fixed base structure. 相似文献

The Cambodian conflict and the increase of the Cold War tension following the Soviet invasion of Afghanistan posed major challenges to Japan’s Southeast Asia policy but, contrary to what is claimed in the existing research, did not halt Tokyo’s efforts to promote peaceful coexistence between the countries of ASEAN and Indochina. Declassified documents and other primary sources show that through the adoption of a twin-track diplomatic line, Japan acted as an “Asian member of the West”, committing to the anti-Soviet alignment but at the same time continuing to pursue its regional objectives. By engaging Vietnam and striving for a “regional” solution to the Cambodian conflict, Japan followed an independent diplomatic line, eventually expanding its role in Southeast Asia beyond the economic dimension to security issues. In the end, Japan’s bridging efforts in Southeast Asia, envisioned by Prime Minister Fukuda in 1977, helped Tokyo to lay the foundation for its involvement in the mature stage of the Cambodian peace process after the late 1980s. 相似文献

A comparative examination of food practices is useful for assessing the nature of diverse forms of social inequality. This article examines three key contexts in which to evaluate the relationship between social differentiation and food practices in the Andes: early complex societies, pre-Columbian states and nonstate complex societies, and colonial societies. A review of these distinct contexts suggests that social and subsistence change may follow different rhythms and that food-related differentiation, just like other forms of social differentiation, is neither consistently augmented in a scalar fashion in relation to “degrees” of social complexity, nor is it in all cases a direct indicator of economic inequality. 相似文献

As the number of conservation areas within England continues to rise, it is increasingly important that adequate care and attention be given to their management. If not, the concept will be devalued and initiatives to protect and enhance such areas will not receive sufficient consideration. Conservation Area character appraisals have recently been suggested as a basis for the management of activities within Conservation Areas. This article considers the nature of advice on appraisals, and then the progress of English authorities in undertaking them. It will conclude with a number of issues and concerns which must be tackled if the potential of theses management instruments is to be fully realised. 相似文献

This paper focuses on the long-debated topic of the so-called calcium oxalate films: their origin and meaning but also their
age and original appearance. The restoration of the main facade of the Siena Cathedral provided a unique opportunity to this
end, thanks to the possibility of an extensive and detailed sampling and (as rarely happens) a sufficiently accurate historical
knowledge of the construction vicissitudes. This work, mainly based on a polarising microscopy study (coupled with X-ray diffraction
and SEM-EDS analyses) of over a thousand thin and ultra-thin sections of 400 microsamples, demonstrates that the current relicts
of films are the result of alteration and decay of ancient treatments. In most cases, these were linseed oil-based glazings
(the use of this substance is confirmed by historical documents) and pigments. Their role was essentially aesthetic; their
use dates the beginning of the fourteenth century and continued at least until the eighteenth century.

This article examines the rationale behind the Heath government's1970 decision to negotiate a Five Power Defence agreement withAustralia, New Zealand, Singapore and Malaysia and to maintaina small British military contingent in Southeast Asia as a partof this new politico-military framework. It argues that whileits overriding foreign policy concern was to end Britain's problematicrelationship with the European Economic Community and to makemembership of this grouping the cornerstone of its foreign policy,the Heath government was careful not to cast Britain's post-imperialfuture in purely European terms. The successful negotiationof the Five Power Defence Arrangements in 1970–71 wasinstrumental in achieving this by ensuring that London wouldmaintain close links with key Commonwealth partners in the Asianregion. In what was not only an attempt to neutralize potentialdomestic opposition to Britain's entry into the EEC, but alsoa lingering reluctance to do away with the rhetoric of Britainas a leading power with extra-European interests, Heath waseager to show that by making a contribution to the stabilityof Southeast Asia, Britain still had a role to play outsideEurope. 相似文献
