Medical-Geographic Forecasting in New Development Areas

The author outlines a methodology for drawing up medical-geographic forecasts of the possible effect on public health of environmental changes produced by new area development. Special attention is devoted to the problem of tick-borne encephalitis. From a theoretical point of view, medical geography is regarded as a bridge between nature and man, tending to promote an integrated geography concerned with the system: nature—man—population—production.     

The Significance and Role of Sectoral-Production Complexes in the Formation and Evolution of Economic Regions

Soviet economic regionalization has traditionally focused on the concept of the areal-production complex (or territorial-production complex), representing the aggregate of economic activities within a particular area. These complexes may range in scale from a local group of interrelated activities all the way to the national economic complex of the USSR. A Soviet economic geographer specializing in the Northern Caucasus now introduces the concept of the “sectoral-production complex” as a subdivision of the areal complex. The sectoral complex contains one or more sectors of production that are linked by a common resource base and common economic relations; for example, the agricultural complex, comprising farming and agricultural processing, rests on agricultural resources; the metallurgy and machine-building complex, combining metallurgy and metal fabrication, rests on a common ore-resource base. According to the author, the concept of a sectoral-production complex must be differentiated from N. N. Kolosovskiy's concept of “energy-and-production cycles” [see Journal of Regional Science, 3 (1961), pp. 1–25] on the ground that Kolosovskiy's cycles are based on a common basic technology, while the sectoral complex involves common resources and economic relations.     

Placers of the Urals,Their Formation,Distribution and Elements of Geomorphic Prediction

The gold, platinum and titanium placers are analyzed from the geomorphic point of view to establish future prospects as the Quaternary placers now being worked become depleted. The key to placer prospecting is seen in the historical sequence of deposition and redeposition in which older placers in turn became source areas for younger placers. The main metallogenetic epoch is associated with the Middle and Late Jurassic as well as a substantial part of the Cretaceous when intensive weathering of the regolith yielded rich placer accumulations in Mesozoic erosional-structural depressions that represent segments of the drainage net of the period. These depressions subsequently were the source areas for new placers as the drainage pattern was reoriented. In some areas crustal movements played a role as renewed erosion induced by uplifting resulted in the redeposition of metal in new placers. As the Quaternary placers become depleted, an effort is therefore recommended to focus prospecting and exploration in the source areas associated with the Mesozoic depressions.     

晚明陈和之款紫砂壶

宜兴紫砂壶是有着深厚的传统文化精神的民间工艺品,早在晚明时期就为人喜爱。其重要原因是因为紫砂壶由＂文人参与＂而制成。它讲究胎土的选料、泥料的淘炼都要精细醇厚;捏塑工艺要精巧雅致;同时与诗、书、画、刻作为器表的装饰,充分表现出紫砂壶是中国特有的一种蕴合传统文化和人文精神的艺术品,所以至令紫砂的魅力仍不减。

The long-ranging macroalga Grypania spiralis from the Ediacaran Doushantuo Formation,Guizhou, South China

Wang, Y., Wang, Y. & Du, W., February 2016. The long-ranging macroalga Grypania spiralis from the Ediacaran Doushantuo Formation, Guizhou, South China. Alcheringa 40, xxx–xxx. ISSN 0311-5518

Grypania spiralis (Walcott) Walter et al., a macroalga previously reported in pre-Ediacaran successions, has been collected, together with abundant macrofossils (i.e., the Wenghui biota), from black shales of the upper Doushantuo Formation (ca 593 to 551 Ma) in northeastern Guizhou, South China. Morphologically, G. spiralis represents a carbonaceous ribbon with a continuum of forms from coiled to nearly straight. Its helicoid main body might have been suspended in the water column for photosynthesis with one end anchored or nestled into soft sediments. Grypania possessed morphological stability, and its habit endowed great competitiveness for sunlight. Remarkably, it did not change significantly in size or morphology over more than 1200 Myrs.

法老时代埃及王权的演进

法老王权在整个古代世界文明中是极具特色的,它几乎成为古埃及文明的象征;同时,它也与埃及国家的兴起、强大、顶峰、分裂和埃及文明的形成、发展、昌盛、衰落息息相关。从法老王权的演进可以看到整个古埃及文明的行进脉络。
