Greater economic cooperation between the two socioeconomic systems in Europe is held to be mutually beneficial and to be favored by some of the continent's physical-geographical aspects (deeply indented coastline, easy overland transportation, resource complementarity). An area deserving priority in all-European projects is the interconnection of power systems to make possible the transmission of electricity covering peak load needs and other requirements. Such interconnections may save significant capital investment that would otherwise be required for additional generating capacity within each system. Other potential areas for all-European cooperation include the provision of east-west inland waterways, motor roads and improved rail lines. One aspect of the possible integration of transport systems would be the organization of overland container traffic between Europe and Japan (as well as Iran and Afghanistan) through the territory of the USSR.  相似文献

This paper responds to that aspect of Andrew Sherratt??s writings that argued for building specifically archaeological theory. In describing a theory of entanglement, I have focused on the archaeological sensitivity to the complexities and practical interlacings of material things. The theory argues that human?Cthing entanglement comes about as a result of the dialectic between dependence (the reliance of humans and things on each other) and dependency (a constraining and limiting need of humans for things). Andrew??s discussion of the role of the wheel in his Secondary Products Revolution is a good example of how humans and things have become entangled so that, over the long term, we have been channeled down particular evolutionary pathways.  相似文献

Abstract

Within the framework of the project Restoring Underwater started in 2001, the ISCR Marine Biology sector with the ISCR Underwater Archaeology Operation Unit has begun a study of the deterioration of stone artefacts exposed to marine environments (Torre Astura – Nettuno; Baiae – Naples). These studies have allowed to better understanding the factor of degradation by biological, mineralogical, and petrographic analyses and to develop measures for the protection in situ of cultural heritage. Based on what was recorded, usually the bioerosion presents various degrees of gravity: limited and sporadic damage or very serious alterations. Depending on their chemical composition, the artefacts proved to be particularly susceptible to the action of corrosion exercised by perforating animal and plant organisms.

This phenomenon becomes more significant in the case in which the artefacts remain exposed and in the same position for a long period of time. It is possible to confirm that the combined action of attack from clionides (sponges) and bivalves can lead, over time, to the total destruction of portions of the artefact (macroboring). As well as these more macroscopic types of damage, there was evidence of the widespread presence of microscopic bioerosion (microboring), caused by autotrophic and heterotrophic microorganisms, visible only through SEM observations, which, despite not creating large chambers, progressively undermine the resistance of the stone and facilitate the development of other biodeteriogens. This paper will be focused on the characterization of the bioerosion observed on different artefacts: the roman statues discovered underwater in the Grotta Azzurra, Capri and in the Campi Flegrei area (Naples –Italy), and the marble sarcophagi that are still on the seabed of San Pietro in Bevagna (Taranto – Italy).  相似文献

Coastal shorelines worldwide are generally unstable and changing. The study of the precise relation between any archaeological site and the shoreline at the time when the site was used is therefore complicated, but still often not met with appropriate methodological approaches. In this article, we test models based on phosphate analysis and discuss how they can be used to detect ancient shorelines. We propose that a model of increased and oscillating phosphate values at the former water level is considered reliable and useful in areas with advancing shoreline.  相似文献

The concentration of research and development in the San Francisco Bay area is found to have attracted related aerospace and electronics industries, thus giving rise to a new type of economic region focused on research activities. The atomic and aerospace industry of New Mexico arose because of the need of having manufacturing facilities near testing grounds and missile ranges in desert areas, but is virtually unrelated to the rest of the New Mexico economy. Industries not dominated by any particular locational factor are being attracted to the dry subtropics of the United States, where the provision of water supplies and refrigeration and air-conditioning produces attractive living conditions for a skilled labor force. Advances in computer technology and electrical communications facilitate centralized industrial management and thus affect plant location.  相似文献

… with a rule and a pair of scales, and the multiplication table always in his pocket, Sir, ready to weigh and measure any parcel of human nature, and tell you exactly what it comes to. It is a mere question of figures, a case of simple arithmetic. Mr Gradgrind in Dickens's Hard Times. Research has indicated that in rural areas, the income of the poor has increased faster than that of the rich … in 1967, 9 out of 10 Indonesians lived below the poverty line; in 1970, 8 out of 10, and in 1976 only 3 out of 10. This means the benefits of development are being distributed … How do we react to these figures? One may still suggest various reservations concerning the indicators of increasing equality. For example, it should be made clear to the layman to what extent the poverty line standard based on the World Bank research is sufficiently valid and objective to be used as a measure and a guide for Indonesian society. We also need further clarification of the more rapid income increases among the poor compared to the rich in rural society. For according to other research, they say that the gap between land-owners and labourers is also increasing. Kompas editorial, 18 August, 1977, Jakarta (translated).  相似文献
