The author develops a system of indices to measure the level and economic effectiveness of regional specialization of major economic regions of the USSR. These indices express the degree of intensity of the specialization of a given region in a certain type of product and the relative cost advantage of such a region over other regions or the country as a whole. 相似文献

Cost minimization criteria are applied to a study of the optimal location of plants for the manufacture of service-industry machines, including street-cleaning equipment, laundry, and dry-cleaning machines. Future national and regional demand for such machines is estimated. The matrix technique is used to identify the economic region for which the aggregate cost of production and transportation of service-industry machines would be minimized. That region is found to be the Volga-Vyatka region, where the estimated cost of producing 315 million rubles worth of service-industry machines is put at 19.5 million rubles. The author does not necessarily exclude the location of manufacturing plants in other regions, if the purpose is to provide employment, as in areas of depleted mineral deposits of the Urals and the Donets Basin or in the agricultural districts of the Southwest and Central Asia. 相似文献

al-Tikha is a mid to large Umm an-Nar (c. 2700–2000 BC) settlement situated near Rustaq at the back of the Southern Batinah coastal plain in the Sultanate of Oman that was discovered (or rediscovered) in 2014. The site is unique because its layout and spatial organisation are very largely (possibly completely) visible on the surface. This includes two separate areas of stone-built housing, a large pottery scatter of varying density, three or four typical Umm an-Nar round towers and a small cemetery consisting of at least four tombs, along with a few other features. The layout of the site is described and discussed in detail, in particular, in relation to what it might tell us about the nature of Umm an-Nar settlement and social organisation more generally. The location of the site within a pattern of repeating Umm an-Nar settlement along Wadi Far (Wādī al-Farʿī) is also described and discussed. 相似文献

Landscape archaeology, as a type of research based on a systemic surface survey and that results in quantifiable datasets of high quality, has started to be practiced in southeastern Arabia only in recent years. In this paper, I will briefly review the short history of landscape archaeology in the area and its relevance. I will then present the approach and methods used in the Wadi al Jizzi Archaeological Project and discuss some of the results obtained to discuss both the potential and problems of the data that the project generated. In particular, I will focus on ephemeral sites and assemblages, data quality and data representativity. 相似文献

Pre‐Romanesque murals at Kosto?any pod Tríbe?om, Slovakia, have been investigated by portable X‐ray fluorescence and by microanalytical methods to identify painting materials (pigments and binders), and to explain the degradation of colours. Today, missing green and blue shades have been reconstructed according to residual concentrations of Cu, which correspond to copper chlorides—products of salt corrosion of the copper carbonates azurite and/or malachite, accelerated by micro‐organisms. As confirmed by powder X‐ray microdiffraction, original minium (Pb3O4) has been transformed to brown–black plattnerite (PbO2). In increased humidity, even insoluble pigments are washing down from the walls and the intensity of colours further diminishes. 相似文献
