[en] Uraineftegas, a subsidiary of Russian oil giant Lukoil, has started up Siberia's first modular crude distillation unit. The 2,000 b/d refinery was designed and manufactured by Ventech Engineers Inc., Pasadena, Tex. Uraineftegas is based in Urai, Siberia. Located in the Tyumen region on the Konda river, the remote town is accessible only by air and water. Most of Urai's crude production--about 50,000 b/d, according to Ventech president Bill Stanley--is shipped by pipeline to the refining centers at Ufa and Omsk. Because there are no products pipelines in which to ship fuels back to Urai, the town needed a small refinery in order to produce its own fuels. This report briefly describes the design ad operation of these modular units. It describes construction techniques and temperature control equipment used to maintain an operational environment under severe winter weather
[en] A survey of the latest results from experiments devoted to studying the structure of nuclei and nuclear-reaction mechanisms by means of accelerated radioactive beams is given. Results obtained in Dubna with the aid of the DRIBs accelerator complex and at other radioactive-beam factories are presented.
[en] For the purpose of investigation and control of the changes in the natural environment of the northern regions of Western Siberia, a special service of engineering-geological monitoring (IGM) was created within the system of the USSR State Gas Concern. The engineering-geological monitoring of geotechnical systems involves tracking, evaluation, analysis and prediction of ongoing changes in their geologic environment and their negative after-effects for interacting technosphere objects. Also, scientific and engineering substantiation of preventive and restorative measures and other management decisions as well as technological provisions for their realization are included. In addition to observing the state of the geologic environment (settling and displacement of buildings, structures and communications, causes of deformation and forecasting their further development) the main tasks of this service are the elaboration of scientifically grounded recommendations and design concepts for prevention and elimination, recultivation of damaged landscapes, development of repair and restoration work technology and participation in performing responsible operations. Most important of the latter are stabilization of damaged soil bases, consolidation of deformed foundations, curing and recultivation of damaged and polluted areas of the geologic environment, recovery of water-intake wells and industrial effluent-disposal wells. The leading establishment of this service is the Trust of Engineering-Geological Monitoring and Research (TIGMI) in Novy Urengoy. TIGMI maintains close contacts with the USSR National Global Change Committee through the Geophysical Committee of the USSR Academy of Sciences. The Trust activities are presented in the first part of the Global Change Data Bank Catalogue
[en] Problems created by oil and gas field development in Arctic regions attract much attention in the discussion of the interaction of civil and industrial buildings and structures with permafrost. The investigations carried out must permit the evaluation of changes in the natural environment and single out the anthropogenic component of these changes, must ensure accident-free operation of oil and gas transport units, safety of people and environmental control in the mineral resource production regions of the Arctic. Taking the pipeline-environment system example, this report characterizes the spatial-temporal structure of the gas transport geotechnical system as a natural-anthropogenic, physico-geographical object. The natural subsystem of this object consists of several structures (referred to as areas and zones). These structures are characterized by different dynamics of regeneration processes of anthropogenic disturbances. It is found that the most negative ecological consequences during the development of the regions at the boundary of tundra and forest-tundra are associated with the disturbances of pre-tundra forests. The least perceptible ecological changes are typical for anthropogenic transformation of bog geo-systems. The anthropogenic structures, which are formed here, are characterized by a state most similar to the initial conditions and, often, by an increase of biomass in the landscapes. All these data are presented according to the author's investigations in the permafrost zone of Western Siberia
[en] Humans have traditionally cultivated steppe and forest-steppe on fertile soils for agriculture. Forests are predicted to shift northwards in a warmer climate and are likely to be replaced by forest-steppe and steppe ecosystems. We analyzed potential climate change impacts on agriculture in south-central Siberia believing that agriculture in traditionally cold Siberia may benefit from warming. Simple models determining crop range and regression models determining crop yields were constructed and applied to climate change scenarios for various time frames: pre-1960, 1960–90 and 1990–2010 using historic data and data taken from 2020 and 2080 HadCM3 B1 and A2 scenarios. From 50 to 85% of central Siberia is predicted to be climatically suitable for agriculture by the end of the century, and only soil potential would limit crop advance and expansion to the north. Crop production could increase twofold. Future Siberian climatic resources could provide the potential for a great variety of crops to grow that previously did not exist on these lands. Traditional Siberian crops could gradually shift as far as 500 km northwards (about 50–70 km/decade) within suitable soil conditions, and new crops nonexistent today may be introduced in the dry south that would necessitate irrigation. Agriculture in central Siberia would likely benefit from climate warming. Adaptation measures would sustain and promote food security in a warmer Siberia.
[en] Cloudina-morph fossils in Siberia have been traditionally regarded as a taphonomic mode of Anabarites tests inserted one into another under specific hydrodynamic conditions. Clusters of telescoped conical tests are ubiquitous in the Kessyusa Group and coeval strata across Siberia and not all of them can be easily interpreted as a result of simple mechanical stacking. It remains to be confirmed whether any of these clusters actually represents a life association of a Cloudina-morph structure.
[es]En Siberia los morfotipos de Cloudina han sido tradicionalmente considerados como una variedad tafonómica de conchas de Anabarites, insertadas una dentro de otra, bajo condiciones hidrodinámicas específicas. Las asociaciones de conchas cónicas telescópicas son omnipresentes en el Grupode Kessyusa y en estratos contemporáneos a lo largo de Siberia, y no todos ellos pueden ser fácilmente interpretados como resultado de un simple apilamiento mecánico. Queda por ver si alguna de estas bioacumulaciones representa una asociación de vida de una estructura morfotípica de tipo Cloudina.
[en] At the Joint Institute for Nuclear Research, Dubna, work is proceeding successfully on the application of particle physics techniques to medico-biological research. One of the topics of interest is the use of wire chambers in molecular biology. These detectors considerably shorten the processing of lamellar radiochromatograms
[en] In April a 64 kbit/s computer communication link was set up between the Joint Institute for Nuclear Research (JINR), Dubna (Russia) and Gran Sasso (Italy) Laboratories via nearby ground satellite stations using the INTELSAT V satellite. Previously the international community of Dubna's experimentalists and theorists (high energy physics, condensed matter physics, low energy nuclear and neutron physics, accelerator and applied nuclear physics) had no effective computer links with scientific centres worldwide
[en] This year, as CERN celebrates its 40th anniversary (November, page 26), not far behind in the celebration stakes is the Joint Institute for Nuclear Research, Dubna, near Moscow, established in 1956. While CERN's goal was to provide a physics platform on which to rebuild Western European science after World War II, JINR had a similar mission for the USSR and the socialist countries, including Eastern Europe
