This paper develops the notion of “event seizure” to better understand how mega-events, and the elites associated with them, take possession of host cities and societies—of development plans, funds and legislation—and impose their priorities on cities and citizens. It illustrates how event seizure plays out in the preparations for the Football World Cup 2018 in Russia, which is on course to become the most expensive World Cup ever with a total cost of about USD 20 billion. Drawing on government and FIFA documents, public statements from authorities and officials, and media coverage, the paper examines three different dimensions of event seizure. First, infrastructural seizure, where event-related infrastructure, particularly sports venues, crowd out infrastructure that serves wider urban needs. Second, financial seizure, where a close circle of political and business elites benefits from state funding, while the public underwrites cost overruns. Third and last, legal seizure, where the event introduces exceptional legislation, infringing citizen rights and compromising due oversight of event preparations.  相似文献

Roderick Impey Murchison named the Permian Period in 1841 based on his work on Lower Permian marine sediments around the city of Perm’, on the west flank of the Ural Mountains. However, he had observed post-Carboniferous red beds earlier, around the town of Vyazniki, west of Moscow, lying above the classic Carboniferous limestones of the Moscow Basin. Murchison's notebooks and papers show that he and colleagues equivocated about the exact age of these red beds, whether latest Permian or early Triassic, but he always favoured the former view. So, his initial observation of the Vyazniki redbeds provided a marker for the top of the Permian and base of the Triassic in the European Russian platform.  相似文献

Artesian basins contain the largest mineral water resources of the world. There are several types of mineral therapeutic water: sulfate, chloride, radon-rich, iron-rich waters, etc. Artesian basins occupy very large areas in Russia. However, genesis of water and brines is still not very clear. This is one of the most important hydrogeological problems that is being attempted to solve for many years. Most of the Russian hydrogeologists traditionally consider that these waters are of sedimentary origin. However, higher concentrations of bromine, iodine, iron, radon and other balneologically active components can be of different origin, for example, of infiltration or juvenile water. As an example, two areas will be considered – West-Siberian basin and East-European artesian area.West-Siberian artesian basin has very distinct latitudinal and vertical zonation. Latitudinal zonation is caused by climate changes from north to south. As for the vertical zonation, mineralization and chemical composition change in the vertical cross-section and from the periphery to the center within the same aquifer. The main mineral water resources of West-Siberian artesian basin are concentrated in Mesozoic rocks. Brackish waters and low-saturated brines without specific components are used for medical purposes. The most well-known spa is Karachi, which exploits chloride-hydrocarbonate brackish water. Sodium chloride bromine and iodine-bromine waters are used at other health resorts. It is possible to organize extraction of iodine from brines of Tcherkashinsko-Tobolskoe occurrence in Tumen region.East-European artesian area occupies most of the Russian Platform. The most widespread types of mineral water within the Russian Platform are sodium-chloride and magnesium-sulfate waters and brines. Such well-known spas, like Moscow mineral waters, Krainka, Staraya Russa and many others, belong to this type. Resources of these waters are definitely connected with sedimentogenic processes. The upper hydrodynamic zone contains iron-rich, hydrogen sulfide, and sometimes radon-rich water. Their formation is caused by the interaction between waters of infiltration and sedimentary genesis, or between infiltration waters and host rocks. One of the examples is Polustrovo iron-rich water. There are industrially valuable waters containing bromine and iodine.The resources of therapeutic water of sedimentary basins allow to increase balneological potential of spas in Russia.  相似文献

Data of 34 elements, including heavy metals, halogens, rare earth elements, U, and Th in 139 moss samples, collected in Central Russia in 2000–2002 in the Tver and Yaroslavl regions and in the northern part of the Moscow region, are presented. Factor analysis with VARIMAX rotation was applied to identify possible sources of the elements determined in the mosses. The seven resulting factors represent crust, vegetation and anthropogenic components. Some of the factors were interpreted as being associated with ferrous smelters (Fe, Zn, Sb, Ta); combination of non-ferrous smelters and other industries (Mn, Co, Mo, Cr, Ni, W); an oil-refining plant, and oil combustion at the thermal power plant (V, Ni). The geographical distribution patterns of the factor scores are also presented. Dependency equations of elemental content in mosses versus distance from the source were derived.  相似文献

We conducted moment tensor inversion and studied source rupture process for M S=7.9 earthquake occurred in the border area of China, Russia and Mongolia on September 27 2003, by using digital teleseismic P-wave seismograms recorded by long-period seismograph stations of the global seismic network. Considering the aftershock distribution and the tectonic settings around the epicentral area, we propose that the M S=7.9 earthquake occurred on a fault plane with the strike of 127°, the dip of 79° and the rake of 171°. The rupture process inversion result of M S=7.9 earthquake shows that the total rupture duration is about 37 s, the scalar moment tensor is M 0=0.97×1020 N·m. Rupture mainly occurred on the shallow area with 110 km long and 30 km wide, the location in which the rupture initiated is not where the main rupture took place, and the area with slip greater than 0.5 m basically lies within 35 km deep middle-crust under the earth surface. The maximum static slip is 3.6 m. There are two distinct areas with slip larger than 2.0 m. We noticed that when the rupture propagated towards northwest and closed to the area around the M S=7.3 hypocenter, the slip decreased rapidly, which may indicate that the rupture process was stopped by barriers. The consistence of spatial distribution of slip on the fault plane with the distribution of aftershocks also supports that the rupture is a heterogeneous process owing to the presence of barriers.  相似文献

俄罗斯和中亚五国地域辽阔,土地、森林、水、能源等自然资源丰富,尤其是有色金属矿藏,种类配套齐全,在世界都占有重要地位。俄罗斯和中亚五国与中国在地缘、历史和文化等多方面有着悠久的历史,具有资源开发、经贸合作和科技交流的国际背景和有利条件。俄罗斯和中亚五国十分重视资源开发和原料出口,向主要经济合作伙伴推销资源产品,并很快引起许多国家,尤其是经济发展较快国家的重视。在未来的几年中,中国与俄罗斯和中亚五国在土地、电力、建材、机械、畜牧业、信息、交通等领域都有着广阔的合作空间。可以说,中国与俄罗斯和中亚五国及其辐射地区市场潜力巨大,待开发的领域空白点较多,特别是里海、西伯利亚的石油和天然气,是21世纪全球最具能源开发前景的地区,而能源勘探与开采领域则是我们未来需要重点发展合作的领域。但是,中亚国家的原料型经济倾向,参与世界经济一体化程度不足,生产和社会基础薄弱,这些问题都阻碍着中亚国家的可持续发展。特别是中亚国家的加工工业和轻工业相对落后,大部分日用消费品依靠进口。这是我国在中亚区域经济合作中充分发挥市场优势、加工业优势的有利条件。所以,资源和经济技术的互补性,对发展中国与中亚五国和俄罗斯双边的区域经济合作都将起到积极作用。展望21世纪的俄罗斯、中亚五国与中国的经贸合作关系,根据俄罗斯和中亚各国资源状况实地调查和统计资料等,对区域资源开发现状与潜力进行了分析,对共同面对的问题,合作的基础和条件及合作前景,都进行了探讨。  相似文献

Three lake sediment sequences (lakes Nero, Chashnitsy, Zaozer’e) from the Rostov-Jaroslavl’ region north of Moscow were studied to provide information on palaeoclimatic and palaeoenvironmental changes during the past 15,000 cal yr. The multi-proxy study (i.e., pollen, macrofossils, mineral magnetic measurements, total carbon, nitrogen and sulphur) is chronologically constrained by AMS 14C measurements. Lake Nero provided the longest sedimentary record back to ca. 15,000 cal yr BP, while sediment accumulation began around ca. 11,000 cal yr BP in the two other lakes, possibly due to melting of permafrost. Limnic plant macrofossil remains suggest increased lake productivity and higher mean summer temperatures after 14,500 cal yr BP. While the late glacial vegetation was dominated by Betula and Salix shrubs and various herbs, it appears that Betula sect. Albae became established as early as 14,000 cal yr BP. Major hydrological changes in the region led to distinctly lower lake levels, starting 13,000 cal yr BP in Lake Nero and ca. 9000 cal yr BP in lakes Chashnitsy and Zaozer’e, which are situated at higher elevations. These changes resulted in sedimentary hiatuses in all three lakes that lasted 3500–4500 cal yr. Mixed broad-leaved – coniferous forests were widespread in the area between 8200 and 6100 cal yr BP and developed into dense, species-rich forests between 6100 and 2500 cal yr BP, during what was likely the warmest interval of the studied sequences. Agricultural activity is documented since 500 cal yr BP, but probably began earlier, since Rostov was a major capital by 862 A.D. This apparent gap may be caused by additional sedimentary hiatuses around 2500 and 500 cal yr BP.  相似文献

A moderate pressure / high temperature zonal metamorphic complex in the Tongulack Mountain Ridge, Altai, Russia, is described, and the applicability of the models of magmatic intrusion and fluid flow to explanation of its origin discussed. The Precambrian complex was formed at 500-700℃ and 3.0-5.5 kbars; it is a linear, 25-30 km wide, thermal anticline with a curved axis showing symmetric metamorphic zoning. The metamorphism was isochemical by its nature, as is corroborated by the chemical compositions of the rocks. Four zones can be recognized within the metamorphic complex: chloritic (on the peripheries), cordieritic, sillimanitic and staurolite-out (in the centre). The zones are separated by successive isograds: cordierite, staurolite-in or sillimanite and staurolite-out. It is argued that the origin of the metamorphic zoning can be explained best by a combined fluid-magmatic model; conductive heat flow from the intrusion predominated considerably over the fluid flux in heat transfer: the fluid flow  相似文献
