    In July 2008, the Global Threat Reduction Initiative and the IRT 2000 research reactor in Sofia, Bulgaria, operated by the Institute for Nuclear Research and Nuclear Energy (INRNE), safely shipped 6.4 kilograms of Russian origin highly enriched uranium (HEU) spent nuclear fuel (SNF) to the Russian Federation. The shipment, which resulted in the removal of all HEU from Bulgaria, was conducted by truck, barge, and rail modes of transport across two transit countries before reaching the final destination at the Production Association Mayak facility in Chelyabinsk, Russia. This paper describes the work, equipment, organizations, and approvals that were required to complete the spent fuel shipment and provides lessons learned that might assist other research reactor operators with their own spent nuclear fuel shipments.

    The National Nuclear Security Administration's (NNSA) Highly Enriched Uranium (HEU) Transparency Implementation Program (TIP) monitors and provides assurance that Russian weapons-grade HEU is processed into low enriched uranium (LEU) under the transparency provisions of the 1993 United States (U.S.)-Russian HEU Purchase Agreement. Meeting the Agreement's transparency provisions is not just a program requirement; it is a legal requirement. The HEU Purchase Agreement requires transparency measures to be established to provide assurance that the nonproliferation objectives of the Agreement are met. The Transparency concept has evolved into a viable program that consists of complimentary elements that provide necessary assurances. The key elements include: (1) monitoring by technical experts; (2) independent measurements of enrichment and flow; (3) nuclear material accountability documents from Russian plants; and (4) comparison of transparency data with declared processing data. In the interest of protecting sensitive information, the monitoring is neither full time nor invasive. Thus, an element of trust is required regarding declared operations that are not observed. U.S. transparency monitoring data and independent instrument measurements are compared with plant accountability records and other declared processing data to provide assurance that the nonproliferation objectives of the 1993 Agreement are being met. Similarly, Russian monitoring of U. S. storage and fuel fabrication operations provides assurance to the Russians that the derived LEU is being used in accordance with the Agreement. The successful implementation of the Transparency program enables the receipt of Russian origin LEU into the United States. Implementation of the 1993 Agreement is proceeding on schedule, with the permanent elimination of over 8,700 warhead equivalents of HEU. The successful implementation of the Transparency program has taken place over the last 10 years and has provided the

    The primary goal of the Russian Research Reactor Fuel Return (RRRFR) programme is to advance nuclear non-proliferation objectives by eliminating stockpiles of Russian-origin highly enriched uranium (HEU). The RRRFR programme was first conceived during trilateral discussions among the USA, the Russian Federation and the IAEA, initiated in 1999, when participants identified more than 20 research reactors in 17 countries having Russian/Soviet supplied fuel. In 2000, the Director General of the IAEA sent a letter to 15 countries asking for their willingness to return HEU spent fuel to the Russian Federation. Fourteen countries responded positively to the Director General's letter. In 2004, the Russian Federation and the USA signed a Government-to-Government Agreement concerning cooperation to return the Russian produced research reactor nuclear fuel to the Russian Federation. This agreement established the legal framework necessary for the cooperation between the Russian Federation and the USA for the return of Russian supplied research reactor fuel from eligible countries. Under the Bratislava agreements concluded by Presidents George W. Bush and Vladimir Putin in February 2005, both countries committed to completing all shipments of Russian-origin HEU spent fuel currently stored outside research reactors by the end of 2010. Up to the time of writing (May 2009) the programme has completed 19 shipments totalling over 838 kg of Russian-origin HEU spent and fresh fuel which has been returned from Bulgaria, the Czech Republic, Germany, Kazakhstan, Latvia, the Libyan Arab Jamahiriya, Poland, Romania, Serbia, Uzbekistan and Vietnam. During this time, the programme successfully removed all HEU from two countries, Latvia and Bulgaria. HEU spent fuel shipments have been the most complex shipments under the RRRFR programme, which will be the focus of this publication. The first shipment of HEU spent fuel from Uzbekistan was completed in January 2006, followed by HEU spent fuel

    Romania safely air shipped 23.7 kilograms of Russian origin highly enriched uranium (HEU) spent nuclear fuel from the VVR S research reactor at Magurele, Romania, to the Russian Federation in June 2009. This was the world’s first air shipment of spent nuclear fuel transported in a Type B(U) cask under existing international laws without special exceptions for the air transport licenses. This shipment was coordinated by the Russian Research Reactor Fuel Return Program (RRRFR), part of the U.S. Department of Energy Global Threat Reduction Initiative (GTRI), in cooperation with the Romania National Commission for Nuclear Activities Control (CNCAN), the Horia Hulubei National Institute of Physics and Nuclear Engineering (IFIN-HH), and the Russian Federation State Corporation Rosatom. The shipment was transported by truck to and from the respective commercial airports in Romania and the Russian Federation and stored at a secure nuclear facility in Russia where it will be converted into low enriched uranium. With this shipment, Romania became the 3rd country under the RRRFR program and the 14th country under the GTRI program to remove all HEU. This paper describes the work, equipment, and approvals that were required to complete this spent fuel air shipment.

    In June 2009 two air shipments transported both unirradiated (fresh) and irradiated (spent) Russian-origin highly enriched uranium (HEU) nuclear fuel from two research reactors in Romania to the Russian Federation (RF) for conversion to low enriched uranium (LEU). The Institute for Nuclear Research at Pitesti (SCN Pitesti) shipped 30.1 kg of HEU fresh fuel pellets to Dimitrovgrad, Russia and the Horia Hulubei National Institute of Physics and Nuclear Engineering (IFIN-HH) shipped 23.7 kilograms of HEU spent fuel assemblies from the VVR-S research reactor at Magurele, Romania, to Ozersk, Russia. Both HEU shipments were coordinated by the Russian Research Reactor Fuel Return Program (RRRFR) as part of the U.S. Department of Energy Global Threat Reduction Initiative (GTRI), were managed in Romania by the National Commission for Nuclear Activities Control (CNCAN), and were conducted in cooperation with the Russian Federation State Corporation for Atomic Energy Rosatom and the International Atomic Energy Agency (IAEA). Both shipments were transported by truck to and from respective commercial airports in Romania and the Russian Federation and stored at secure nuclear facilities in Russia until the material is converted into low enriched uranium. These shipments resulted in Romania becoming the 3rd country under the RRRFR program and the 14th country under the GTRI program to remove all HEU. This paper describes the research reactor preparations and license approvals that were necessary to safely and securely complete these air shipments of nuclear fuel. (author)

    1993-01-01

    The U.S. has signed an agreement with the Russian Federation for the purchase of 500 metric tons of highly-enriched uranium (HEU) taken from dismantled nuclear weapons. The HEU will be blended down to low-enriched uranium and will be transported to the U.S. to be used by fuel fabricators to make fuel for commercial nuclear power plants. Both the U.S. and Russia have been preparing to institute transparency measures to provide assurance that nonproliferation and arms control objectives specified in the agreement are met. This paper provides background information on the original agreement and on subsequent negotiations with the Russians, as well as discussion of technical aspects of developing transparency measures suited to the facilities and processes which are expected to be involved. Transparency has been defined as those agreed-upon measures which build confidence that arms control and non-proliferation objectives shared by the parties are met. Transparency is a departure from exhaustive, detailed arms control verification regimes of past agreements, which were based on a presumption of detecting transgressions as opposed to confirming compliance

    In May 2004, the Global Threat Reduction Initiative agreement was signed by the governments of the United States and the Russian Federation. The goal of this initiative is to minimize, in cooperation with the International Atomic Energy Agency (IAEA) in Vienna, the existing threat of misuse of nuclear and radioactive materials for terrorist purposes, particularly highly enriched uranium (HEU), fresh and spent nuclear fuel (SNF), and plutonium, which have been stored in a number of countries. Within the framework of the initiative, HEU materials and SNF from research reactors of Russian origin will be transported back to the Russian Federation for reprocessing/liquidation. The program is designated as the Russian Research Reactor Fuel Return (RRRFR) Program and is similar to the U.S. Foreign Research Reactor Spent Nuclear Fuel Acceptance Program, which is underway for nuclear materials of United States origin. These RRRFR activities are carried out under the responsibilities of the respective ministries (i.e., U.S. Department of Energy (DOE) and Russian Federation Rosatom). The Czech Republic and the Nuclear Research Institute Rez, plc (NRI) joined Global Threat Reduction Initiative in 2004. During NRI's more than 50 years of existence, radioactive and nuclear materials had accumulated and had been safely stored on its grounds. In 1995, the Czech regulatory body , State Office for Nuclear Safety (SONS), instructed NRI that all ecological burdens from its past activities must be addressed and that the SNF from the research reactor LVR -15 had to be transported for reprocessing. At the end of November 2007, all these activities culminated with the unique shipment to the Russian Federation of 527 fuel assemblies of SNF type EK-10 (enrichment 10% U-235) and IRT-M (enrichment 36% and 80% U-235) and 657 irradiated fuel rods of EK-10 fuel, which were used in LVR-15 reactor.

    During the last year after the 16-th International Conference on Reducing Fuel Enrichment in Research Reactors held in October, 1993 in Oarai, Japan, the conclusive stage of the Program on reducing fuel enrichment (to 20% in U-235) in research reactors was finally made up in Russia. The Program was started late in 70th and the first stage of the Program was completed by 1986 which allowed to reduce fuel enrichment from 80-90% to 36%. The completion of the Program current stage, which is counted for 5-6 years, will exclude the use of the fuel enriched by more than 20% from RF to other countries such as: Poland, Czeck Republick, Hungary, Roumania, Bulgaria, Libya, Viet-Nam, North Korea, Egypt, Latvia, Ukraine, Uzbekistan and Kazakhstan. In 1994 the Program, approved by RF Minatom authorities, has received the status of an inter-branch program since it was admitted by the RF Ministry for Science and Technical Policy. The Head of RF Minatom central administrative division N.I.Ermakov was nominated as the Head of the Russian Program, V.G.Aden, RDIPE Deputy Director, was nominated as the scientific leader. The Program was submitted to the Commission for Scientific, Technical and Economical Cooperation between USA and Russia headed by Vice-President A. Gore and Prime Minister V. Chemomyrdin and was given support also.

    Conceptual design of an accelerator driven sub-critical experimental research reactor (ADSRR) was initiated in 1999 at the Vinca Institute of Nuclear Sciences, Serbia and Montenegro. Initial results of neutronic analyses of the proposed ADSRR-H were carried out by Monte Carlo based codes and available high-enriched uranium dioxide (HEU) dispersed Russian type TVR-S fuel elements (FE) placed in a lead matrix. Beam of charged particles (proton or deuteron) would be extracted from the high-energy channel H5B of the VINCY cyclotron of the TESLA Accelerator Installation. In 2002, the Vinca Institute has, in compliance with the Reduced Enrichment for Research and Test Reactors (RERTR) Program, returned fresh HEU TVR-S type FEs back to the Russian Federation. Since usage of HEU FEs in research reactors is not further recommended, a new study of an ADSRR-L conceptual design has initiated in Vinca Institute in last two years, based on assumed availability of low-enriched uranium (LEU) dispersed type TVR-S FEs. Initial results of numerical simulations of this new ADSRR-L, published for the first time in this paper, shows that such a small low neutron flux system can be used as an experimental - 'demonstration' - ADS with neutron characteristics similar to proposed well-known lead moderated and cooled power sub-critical ADS with intermediate neutron spectrum. Neutron spectrum characteristics of the ADSRR-L are compared to ones of the ADSRR-H with the same mass (7.7 g) of 235 U nuclide per TVR-S FE. (author)

    Agreements between the United States (U.S.) and the Russian Federation (R.F.) require the down-blending of highly enriched uranium (HEU) from dismantled Russian Federation nuclear weapons. The Blend Down Monitoring System (BDMS) was jointly developed by the Los Alamos National Laboratory (LANL) and the Oak Ridge National Laboratory (ORNL) to continuously monitor the enrichments and flow rates in the HEU blending operations at the R.F. facilities. A significant requirement of the implementation of the BDMS equipment in R.F. facilities concerned the certification of the BDMS equipment for use in a Russian nuclear facility. This paper discusses the certification of the BDMS for installation in R.F. facilities, and summarizes the lessons learned from the process that can be applied to the installation of other U.S. equipment in Russian nuclear facilities

  19. How is uranium supply affecting enrichment?

    As a result of the enlivened uranium market, momentum has in turn picked up in the enrichment sector. What are the consequences of higher uranium prices? There is, of course, a link between uranium and enrichment supply to the extent that they are at least partial substitutes. On the enrichment supply side, the most obvious feature is the gradual replacement of the old gas diffusion facilities of Usec in the USA and EURODIF in France with more modern and economical centrifuge plants. Assuming Usec can overcome the financing and technical issues surrounding its plans, the last gas diffusion capacity should disappear around 2015 and the entire enrichment market should then be using centrifuges. On the commercial side, the key anticipated developments are mostly in Russia. Although there should still continue to be substantial quantities of surplus Russian HEU available for down blending in the period beyond 2013, it is now reasonable to expect that it will be mostly consumed by internal needs, to fuel Russian-origin reactors both at home and in export markets such as China and India. Finally, as a key sensitive area for the non-proliferation of nuclear weapons, the enrichment sector is likely to be a central point of the new international arrangements which must be developed to support a buoyant nuclear sector throughout this century.

    Full Text Available Our team has been a pioneer in harvesting extracellular vesicles (EVs enriched for neuronal origin from peripheral blood and using them as a biomarker discovery platform for neurological disorders. This methodology has demonstrated excellent diagnostic and predictive performance for Alzheimer's and other neurodegenerative diseases in multiple studies, providing a strong proof of concept for this approach. Here, we describe our methodology in detail and offer further evidence that isolated EVs are enriched for neuronal origin. In addition, we present evidence that EVs enriched for neuronal origin represent a more sensitive and accurate base for biomarkers than plasma, serum, or non-enriched total plasma EVs. Finally, we proceed to investigate the protein content of EVs enriched for neuronal origin and compare it with other relevant enriched and non-enriched populations of plasma EVs. Neuronal-origin enriched plasma EVs contain higher levels of signaling molecules of great interest for cellular metabolism, survival, and repair, which may be useful as biomarkers and to follow response to therapeutic interventions in a mechanism-specific manner.

  1. Environmental assessment for the purchase of Russian low enriched uranium derived from the dismantlement of nuclear weapons in the countries of the former Soviet Union

    1994-01-01

    The United States is proposing to purchase from the Russian Federation low enriched uranium (LEU) derived from highly enriched uranium (HEU) resulting from the dismantlement of nuclear weapons in the countries of the former Soviet Union. The purchase would be accomplished through a proposed contract requiring the United States to purchase 15,250 metric tons (tonnes) of LEU (or 22,550 tonnes of UF 6 ) derived from blending 500 metric tones uranium (MTU) of HEU from nuclear warheads. The LEU would be in the form of uranium hexafluoride (UF 6 ) and would be converted from HEU in Russia. The United States Enrichment Corporation (USEC) is the entity proposing to undertake the contract for purchase, sale, and delivery of the LEU from the Russian Federation. The US Department of Energy (DOE) is negotiating the procedure for gaining confidence that the LEU is derived from HEU that is derived from dismantled nuclear weapons (referred to as ''transparency),'' and would administer the transparency measures for the contract. There are six environments that could potentially be affected by the proposed action; marine (ocean); US ports of entry; truck or rail transportation corridors; the Portsmouth GDP; the electric power industry; and the nuclear fuel cycle industry. These environmental impacts are discussed

    In 1993 the US and the Russian Federation signed an agreement allowing the US to purchase highly enriched uranium (HEU) from Russia over a 20-year period. This Highly Enriched Uranium Purchase Agreement permits the purchase of 500 metric tons of HEU from dismantled Russian nuclear weapons in the form of low-enriched uranium (LEU) for use as power reactor fuel in the US. Under the HEU Agreement, the US and Russia are cooperating in a ''Transparency Program'' to ensure that arms control and nonproliferation objectives are being met. The Transparency Program measures, which are a departure from traditional, intrusive measures of verification, include sending individuals from the US to Russia to monitor the processing of the HEU

    2001-01-01

    The Secretary of Energy of the United States, Spencer Abraham, Minister of the Russian Federation on Atomic Energy, Alexander Rumyantsev, and Director General of the International Atomic Energy Agency (IAEA), Mohamed ElBaradei, met in Vienna on 18 September 2001 to review progress on the Trilateral Initiative. The Initiative was launched in 1996 to develop a new IAEA verification system for weapon-origin material designated by the United States and the Russian Federation as released from their defence programmes. The removal of weapon-origin fissile material from the defence programmes of the Russian Federation and the United States is in furtherance of the commitment to disarmament undertaken by the two States pursuant to Article VI of the Treaty on the Non-Proliferation of Nuclear Weapons (NPT). IAEA verification under this Initiative is intended to promote international confidence that fissile material made subject by either of the two States to Agency verification remains irreversibly removed from nuclear weapon programmes

    The Siberian Chemical Combine (SKhK) is the largest multifunction nuclear production facility in the Russian nuclear complex. Until recently, it produced and processed special nuclear material for the Russian Defense Ministry. SKhK and its US partners in the Department of Energy (DOE) US/Russian Materials Protection, Control, and Accountability (MPC and A) Program are nearing completion of the initial MPC and A upgrades at the six SKhK plant sites that were begun three years ago. Comprehensive enhancements to the physical protection and access control systems are progressing on a site-wide basis while a comprehensive MC and A system is being implemented at the Radiochemical Plant site. SKhK now produces thermal and electrical power, enriches uranium for commercial reactor fuel, reprocesses irradiated fuel, converts high-enriched uranium metal into high-enriched oxide for blending into reactor-grade, low-enriched uranium, and manufactures civilian products. The authors review the progress to date and outline plans for continuing the work in 1999

    The IAEA has been involved for more than thirty years in supporting international nuclear non-proliferation efforts associated with reducing the amount of Highly Enriched Uranium (HEU), whose enrichment is ≥ 20% in 235U, in international commerce. In particular, IAEA projects and activities have directly supported the two main international efforts to return fresh and spent HEU research reactor fuel to the country where it was originally enriched: the United States Foreign Research Reactor Spent Nuclear Fuel (FRRSNF) Acceptance Programme and the United States-IAEA-Russian Federation tripartite initiative known as the Russian Research Reactor Fuel Return (RRRFR) Programme. This report gives an account of IAEA efforts in support of both programmes including a historical overview of fuel return shipments and a brief description of associated cooperation activities carried out by the IAEA.

    2001-01-01

    Russian marine fuel is a trans-national security concern. This paper focuses on specific technical properties of Russian marine nuclear fuel especially relevant for evaluating different aspects on nuclear proliferation, in addition to risks associated with regional environmental degradation and illegal diversion of radiological substances. Russian fresh fuel for marine reactors has been involved in several significant cases of illicit trafficking of special nuclear materials. The amount and quality of nuclear materials in Russian spent marine fuel give also reason for concern. Not less than 200 marine reactor cores are ready for having their spent fuel unloaded and preliminary stored on shore in the Far East and North West of Russia, and large amounts of spent naval fuel have been stored at Russian military bases for decades. In order to assess the security risks associated with Russian spent marine fuel, this paper discusses the material attractiveness of spent fuel from all types of Russian marine reactors. The calculations are based on a model of a light water moderated Russian icebreaker reactor. The computer tool HELIOS, used for modelling the reactor and the reactor operations, has been extensively qualified by comparisons with experimental data and international benchmark problems for reactor physics codes as well as through feedback from applications. Some of these benchmarks and studies include fuel enrichments up to 90% in Russian marine reactors. Several fuel data cases are discussed in the paper, focusing especially on: 1) early fuel designs with low initial enrichment; 2) more modern fuel designs used in third and fourth generation of Russian submarines probably with intermediate enriched fuel; and 3) marine fuel with initial enrichment levels close to weapons-grade material. In each case the fuel has been burned until k eff has reached below 1. Case 1) has been evaluated, the calculations made as basis for this paper have concentrated on fuel with

    The aim of the report is to find some principal decisions to implement an Agreement between the Governments of the Russian Federation and the USA on repatriation of the research reactor spent nuclear fuel (RR SNF) to the Russian Federation. The report presents some ideas and approaches to the transportation of the Russian-origin RR SNF from the technical, economical and legal viewpoints. The report summarizes the Russian experience and possibilities to fulfill the program under the Agreement. Some decisions are proposed related to application of the international transportation experience and the most advanced technologies for the RR SNF handling. At present, there is no any unified SNF transportation technology that is capable to implement the transportation program schedule set by the Agreement. The decision is in the comprehensive approach as well as in the development of mobile and flexible schemes and in implementation of parallel and combined shipments. (author)

    According to the Concept of Russian Minatom on military plutonium excess utilization, the State Scientific Center of Russian Federation ''Research Institute of Atomic Reactors'' (Dimitrovgrad) has begun study on possibility of technological processing of the metal military plutonium into MOX fuel. The Program and the stages of its realization are submitted in the paper. During 1998-2000 the first stage of the Program was fulfilled and 50 kg of military origin metallic plutonium was converted to MOX fuel for the BOR-60 and BN-600 reactor. The plutonium conversion into MOX fuel is carried out under the original technology developed by SSC RIAR. It includes pyro-electrochemical process for production of fuel on the domestic equipment with the subsequent fuel pins manufacturing for the fast reactors by the vibro-packing method. The produced MOX fuel is purified from alloy additives (Ga) and corresponds to the vibro-packed fuel standard for fast reactors. The fuel pins manufacturing for BOR-60 and BN-600 reactors are carried out by the vibro-packing method on a standard procedure, which is used in SSC RIAR more than 20 years. (author)

  14. People of clergy origin among the elite of Russian Empire (XVIII - first quarter of XIX century

    Full Text Available In the present article mechanisms of penetration of persons of clergy origin into the elite of Russian Empire in XVIII - fi rst quarter of XIX century is to be analysed. The term «elite» means the military and state «generals», which achieved 1-5 ranks under the Table of Ranks. We found an extremely small number of people of clergy origin among the elite of Russian Empire. What hindered the advancement of clergy? The author proposes that the significance of the Table of Ranks and of the system of promotion in rank as a social elevator for persons of not-noble origin was overpriced, and also highlights the inertia of pre-Petrine localism. The system of matrimonial ties and of patronage to relatives backed by the economic power based on large land ownership allowed boyar aristocracy get a strong position and high ranks among the new elite during the reforms of Peter the Great. Therefore it was quite difficult for people of clergy and else not-noble origin to achieve high ranks. In addition the Church administration cared about its own personnel and resisted moving of talented seminarists to the civil service. The analysis of the data shows that patronage was one of the decisive factors of vertical social mobility for persons of clergy origin. Many former seminarists entered the civil service, but three cases of seven mentioned in the article are connected with military service. Everyone was under patronage of a powerful authority, often serving as an aide-decamp or a secretary. There were two barriers: the rejection of aristocracy to the priests’ sons and the corporatism of Church administration and education and in general the closedness of clergy of the Synodal period

    2005-01-01

    By the end of August, 2005, the Russia Federation delivered to the United States (U.S.) more than 7,000 metric tons (MT) of low enriched uranium (LEU) containing approximately 46 million SWU and 75,000 MT of natural uranium. This uranium was blended down from weapons-grade (nominally enriched to 90% 235 U) highly enriched uranium (HEU) under the 1993 HEU Purchase Agreement that provides for the blend down of 500 MT HEU into LEU for use as fuel in commercial nuclear reactors. The HEU Transparency Program, under the National Nuclear Security Administration (NNSA), monitored the conversion and blending of the more than 250 MT HEU used to produce this LEU. The HEU represents more than half of the 500 MT HEU scheduled to be blended down through the year 2013 and is equivalent to the elimination of more than 10,000 nuclear devices. The HEU Transparency Program has made considerable progress in its mission to develop and implement transparency measures necessary to assure that Russian HEU extracted from dismantled Russian nuclear weapons is blended down into LEU for delivery to the United States. U.S. monitor observations include the inventory of inprocess containers, observation of plant operations, nondestructive assay measurements to determine 235 U enrichment, as well as the examination of Material Control and Accountability (MC and A) documents. During 2005, HEU Transparency Program personnel will conduct 24 Special Monitoring Visits (SMVs) to four Russian uranium processing plants, in addition to staffing a Transparency Monitoring Office (TMO) at one Russian site

  17. Management of high enriched uranium for peaceful purposes: Status and trends

    International Nuclear Information System (INIS)

    2005-06-01

    Arms control agreements between some Nuclear Weapon States have led to the dismantling of many of the nuclear weapons in their military stockpiles, which in turn have produced stockpiles of excess weapons-grade high enriched uranium (HEU) from the dismantled weapons. Considering the proliferation potential of HEU, the management, control and disposition of this fissile material has become a primary focus of nuclear non-proliferation efforts worldwide. To lessen the proliferation threat of excess HEU stockpiles, the USA agreed to purchase several tonnes of excess Russian HEU down-blended to low enriched uranium (LEU). Proliferation concerns about HEU have also resulted in a global effort to convert research reactors from HEU to LEU fuel and to minimize civilian use of HEU. This publication addresses HEU management declared excesses, non-proliferation programmes and options for the use of HEU stockpiles, including disposition programmes. Also addressed are the influence of LEU derived from surplus HEU on the global market for uranium, technical issues associated with utilization and the disposition of HEU

    In August 2002, the inventory of high-enriched uranium (HEU) fresh fuel at the Vinca Institute in Belgrade, Yugoslavia, was repackaged and shipped to the Russian Federation (R.F.), its country of origin under the former Soviet Union. Several thousand small fuel elements were repackaged by the Vinca Institute into approved shipping containers provided by the RF and loaded onto the approved ground transportation vehicle. The transportation from the Vinca Institute to the Belgrade Airport was done under the planning and protection of Yugoslavian and Serbian military and police organizations, with technical oversight being provided by the Vinca staff that escorted the convoy. Under constant security protection, the Russian crew loaded the fuel containers onto the cargo plane, and later it departed for an airport near Dimitrovgrad, Russia. In addition to the domestic control and accounting provided during this operation, this inventory was under International Atomic Energy Agency (IAEA) safeguards, and its inspectors appropriately confirmed, sealed and documented the inventory. The United States (U.S.) observers were also present, and appropriate data were collected because of nonproliferation interests and contractual support for all phases of the operation. Since this event, the Vinca staff has generated several papers describing the technical background and detailed activities of this operation. This paper describes the removal from the U.S. observers perspectives and recognizes the significant cooperation among the supporting countries and the achievements of the organizations directly involved.

    Full Text Available Fashion exists in all aspects of human life, including language. In this context, we refer to the phenomenon of language fashion, which became an object of linguistic study in Russia at the turn of the 20th/21st centuries. This article is concerned with the phenomenon of buzzwords in modern Russian and Chinese newspaper texts, from the perspective of comparative analysis. In the article, we clarify the meanings of language fashion and buzzwords, discuss the essential features of this linguistic phenomenon, present a classification of buzzwords, characterise the main ways of enlarging this group of lexical units, and analyse the semantic and functional features of these units. The material for analysis is drawn from newspaper texts in online versions of Russian and Chinese mass media resources, for the period 2016-2017. The results of the research show that there are common features between the buzzwords of the two languages. Firstly, from the point of view of origin, the form or meaning of the buzzwords is associated with novelty and a break with tradition. Secondly, in a semantic sense, there are lexical coincidences in the buzzwords of the two languages. Thirdly, in a functional sense, a buzzword in one or another language can act as a pro-ductive model for creating new words, and a stimulus for the realization of new ideas. The conclusion dis-cusses the prospects of studying buzzwords and language fashion in general.

    Since the 1970's, global efforts have been going on to replace the high-enriched (>90% {sup 235}U), low-density UAlx research reactor fuel with high-density, low enriched (<20% {sup 235}U) replacements. This search is driven by the attempt to reduce the civil use of high-enriched material because of proliferation risks and terrorist threats. American initiatives, such as the Global Threat Reduction Initiative (GTRI) and the Reduced Enrichment for Research and Test Reactors (RERTR) program have triggered the development of reliable low-enriched fuel types for these reactors, which can replace the high enriched ones without loss of performance. Most success has presently been obtained with U{sub 3}Si{sub 2} dispersion fuel, which is currently used in many research reactors in the world. However, efforts to search for a replacement with even higher density, which will also allow the conversion of some high flux research reactors that currently cannot change to U{sub 3}Si{sub 2} (eg. BR2 in Belgium), have continued and are for the moment mainly directed towards the U(Mo) alloy fuel (7-10 w% Mo). This paper provides an overview of the past efforts and presents the current status of the U(Mo) development. (authors)

    A genetic stock certification assay was developed to distinguish Russian honey bees from other European (Apis mellifera L.) stocks that are commercially produced in the United States. In total, 11 microsatellite and five single-nucleotide polymorphism loci were used. Loci were selected for relatively high levels of homogeneity within each group and for differences in allele frequencies between groups. A baseline sample consisted of the 18 lines of Russian honey bees released to the Russian Bee Breeders Association and bees from 34 queen breeders representing commercially produced European honey bee stocks. Suitability tests of the baseline sample pool showed high levels of accuracy. The probability of correct assignment was 94.2% for non-Russian bees and 93.3% for Russian bees. A neighbor-joining phenogram representing genetic distance data showed clear distinction of Russian and non-Russian honey bee stocks. Furthermore, a test of appropriate sample size showed a sample of eight bees per colony maximizes accuracy and consistency of the results. An additional 34 samples were tested as blind samples (origin unknown to those collecting data) to determine accuracy of individual assignment tests. Only one of these samples was incorrectly assigned. The 18 current breeding lines were represented among the 2009 blind sampling, demonstrating temporal stability of the genetic stock identification assay. The certification assay will be used through services provided by a service laboratory, by the Russian Bee Breeders Association to genetically certify their stock. The genetic certification will be used in conjunction with continued selection for favorable traits, such as honey production and varroa and tracheal mite resistance.

  9. A confirmatory measurement technique for highly enriched uranium

    International Nuclear Information System (INIS)

    Sprinkle, J.K. Jr.

    1987-07-01

    This report describes a confirmatory measurement technique for measuring uranium items in their shipping containers. The measurement consists of a weight verification and the detection of three gamma rays. The weight can be determined very precisely, thus it severely constrains the options of the diverter who might want to imitate the gamma signal with a bogus item. The 185.7-keV gamma ray originates from 235 U, the 1001 keV originates from a daughter of 238 U, and the 2614 keV originates from a daughter of 232 U. These three gamma rays exhibit widely different attenuation properties, they correlate with enrichment and total uranium mass, and they rigorously discriminate against a likely diversion scenario (low-enriched uranium substitution). These four measured quantities, when combined, provide a signature that is very difficult to counterfeit

    Russian ElectroKhimPribor Integrated Plant, as well as ORNL, is a leading production which manufactures and supplied to the world market such specific products as stable isotopes. More than 200 isotopes of 44 elements can be obtained at its electromagnetic separator. Changes being underway for a few last years in Russia affected production and distribution of stable isotopes. There arose a necessity in a new approach to handling work in this field so as to create favourable conditions for both producers and customers. As a result, positive changes in calutron operation at ElectroKhimPribor has been reached; quality management system covering all stages of production has been set up; large and attractive stock of isotopes has been created; prospective scientific isotope-based developments are taken into account when planning separation F campaigns; executing the contracts is guaranteed; business philosophy has been changed to meet maximum of customer needs. For more than forty years ElectroKhimPribor have had no claim from customers as to quality of products or implementing contracts. Supplying enriched stable isotopes virtually to all the world's leading customers, ElectroKhimPribor cooperates successfully with Canadian company Trace Science since 1996

    The enriched uranium workshops in Cadarache have a double purpose on the one hand to convert uranium hexafluoride into metal or oxide, and on the other hand to recover the uranium contained in scrap materials produced in the different metallurgical transformations. The principles that have been adopted for the design and safety of these workshops are reported. The nuclear safety is based on the geometrical limitations of the processing vessels. To establish the processes and the technology of these workshops, many studies have been made since 1960, some of which have led to original achievements. The uranium hexafluoride of high isotopic enrichment is converted either by injection of the gas into ammonia or by an original process of direct hydrogen reduction to uranium tetrafluoride. The uranium contained m uranium-zirconium metal scrap can be recovered by combustion with hydrogen chloride followed treatment of the uranium chloride by fluorine in order to obtain the uranium in the hexafluoride state. Recovery of the uranium contained m various scrap materials is obtained by a conventional refining process combustion of metallic scrap, nitric acid dissolution of the oxide, solvent purification by tributyl phosphate, ammonium diuranate precipitation, calcining, reduction and hydro fluorination into uranium tetrafluoride, bomb reduction by calcium and slag treatment. Two separate workshops operate along these lines one takes care of the uranium with an isotopic enrichment of up to 3 p. 100, the other handles the high enrichments. The handling of each step of this process, bearing in mind the necessity for nuclear safety, has raised some special technological problems and has led to the conception of new apparatus, in particular the roasting furnace for metal turnings, the nitric acid dissolution unit, the continuous precipitator and ever safe filter and dryer for ammonium diuranate, the reduction and hydro fluorination furnace and the slag recovery apparatus These are

    The Russian RERTR Program started at the end of 70's, the final goal of the program is to eliminate supplies of HEU in fuel elements and assemblies for foreign research reactors that were designed according to Russian projects. Basic directions of the work include: completion of the development of the fuel elements and assemblies on a basis of uranium dioxide; development of the fuel on a basis of U-Mo alloy; and development of pin type fuel elements. Fuel assemblies of WWR-M2 type with LEU were developed and qualified for using in foreign research reactors that use such type of fuel assemblies. These assemblies are ready for the supplying several operating foreign research reactors. There are more than 20 sites in Eastern European countries, former Soviet republics and another countries that have big amount of Russian origin HEU in fresh and spent fuel. The problem of the shipment of SNF from sites of research reactors is also very important for domestic Russian research reactors. More than ten years from its beginning the Russian RERTR program developed practically independently from the international RERTR program and only at the begin of 90's the Russian specialists started to contact with foreign scientists and the exchange of the scientific information has become more intensive. In September 1994, representatives of Minatom and DOE signed a protocol of intent to reduce an enrichment of uranium in research reactors. The main aspects of collaboration involve: Several domestic Russian research reactors such as WWR-M, IR-8 and others were investigated from the point of view of possibility of reducing of enrichment; financial support of the program from US DOE which is insufficient. The important part of international collaboration is the import of Russian origin spent and fresh fuel of research reactors to Russia. In August 2002 an impressive result of the Russian-American collaboration with support of IAEA and with the help and assistance of Yugoslavian side was

    In the future, commercial laser isotope enrichment technologies, currently under development, could make it easier for national to produce highly enriched uranium secretly. The head of a US firm that is developing a laser enrichment process predicts that in twenty years, major utilities and small countries will have relatively small, on-site, laser-based uranium enrichment facilities. Although these plants will be designed for the production of low enriched uranium, they could be modified to produce highly enriched uranium, an option that raises the possibility of countries producing highly enriched uranium in small, easily hidden facilities. Against this background, most of this report describes the current and future quantities of plutonium and highly enriched uranium in the world, their forms, the facilities in which they are produced, stored, and used, and the extent to which they are transported. 5 figures, 10 tables

In the meantime the outlood remains unclear, with the market dominated by a number of developments -privatisation of the United States Enrichment Corp (USEC), increasing availability of Russian and US military inventories, the deployment of advanced technology and the closure of nuclear power plants due to deregulation.

    Full Text Available Abstract Background Many ethnic minority populations have poorer health than the general population. However, there is limited knowledge on the possible ethnic gap in physical mobility. We aim to examine the prevalence of mobility limitations in working-age Russian, Somali and Kurdish origin migrants in comparison to the general population in Finland. We also determine whether the association between ethnic group and mobility limitation remains after taking into account socio-economic and health-related factors. Methods We used data from the Finnish Migrant Health and Wellbeing Study (Maamu and the Finnish Health 2011 Survey. The participants comprised 1880 persons aged 29–64 years. The age-adjusted prevalence of difficulties in various mobility tasks was calculated using predictive margins. Logistic regression analysis was used to examine the association between socio-economic, health- and migration-related factors and mobility limitation (self-reported difficulty in walking 500 m or stair climbing. The association between ethnic group and mobility limitation was calculated using logistic regression analysis. Results Mobility limitations were much more prevalent among Somali origin women (46 % and Kurdish origin men (32 % and women (57 % compared to men and women in the general Finnish population (5–12 %. In Russian origin men and women, the prevalence of mobility limitation (7–17 % was similar to the general Finnish population. Socio-economic and health-related factors, but not migration-related factors (time lived in Finland and language proficiency in Finnish or Swedish, were found to be associated with mobility limitation in the studied populations. Somali and Kurdish origin migrants were found to have increased odds for mobility limitation compared to the general Finnish population, even after adjusting for socio-economic and health-related factors (Somalis odds ratio [OR] 3.61; 95 % confidence interval [CI] 2.07–6.29, Kurds

    Today standard PWR fuel is licensed for operation up to 65-70 MWd/kgU, which in most cases corresponds to an enrichment of more than 5 w/o "2"3"5U. Due to criticality safety reason of storage and transportation, only fuel up to 5 w/o "2"3"5U enrichment is so far used. New fuel storage installations and transportation casks are necessary investments before the reactivity level of the fresh fuel can be significantly increased. These investments and corresponding licensing work takes time, and in the meantime a solution that requires burnable poisons in all pellets of the fresh high-enriched fuel might be used. By using very small amounts of burnable absorber in every pellet the initial reactivity can be reduced to today's levels. This study presents core calculations with fuel assemblies enriched to almost 6 w/o "2"3"5U mixed with a small amount of erbia. Some of the assemblies also contain gadolinia. The results are compared to a reference case containing assemblies with 4.95 w/o "2"3"5U without erbia, utilizing only gadolinia as burnable poison. The comparison shows that the number of fresh fuel assemblies can be reduced by 21% (which increases the batch burnup by 24%) by utilizing the erbia fuel concept. However, increased cost of uranium due to higher enrichment is not fully compensated for by the cost gain due to the reduction of the number assemblies. Hence, the fuel cycle cost becomes slightly higher for the high enrichment erbia case than for the reference case. (author)

    Full Text Available Our paper provides an insight into the universe of Russian multinationals and their influence upon the Romanian economy. Even if statistical data on foreign direct investment stock by country of origin do not prove the existence of Russian capital in Romania, it is a fact that the high values of foreign direct investment stock from the Netherlands, Austria, Germany or Switzerland are largely due to the investment projects undertaken in Romania by Russian multinationals. Despite the lack of relevant statistical data, we can say that the impact of Russian MNC’s on the Romanian economy is huge. Among positive influences we can mention: global employment opportunities for highly qualified workforce in the region; the transfer of advanced technologies to Romanian enterprises and the local markets; the awareness of business partners and public opinion on social responsibility; the insert of higher performance standards, competitiveness and managerial ethics.

  3. Implementation of the United States/Russian HEU Agreement: Current Status and Prospects

    2003-01-01

    During Calendar Year (CY) 2002, the Russian Federation (R.F.) delivered low enriched uranium (LEU) from the conversion and processing of 30 metric tons (MT) of weapons-grade (90% 235 U assay) uranium. Through July 2003, the Highly Enriched Uranium (HEU) Transparency Implementation Program (TIP) will have monitored the conversion of over 190 MT HEU into LEU. This total represents about 38 percent of the projected 500 MT HEU scheduled to be blended down through the year 2013 and is equivalent to the destruction of 7,600 nuclear devices. The National Nuclear Security Administration's (NNSA) HEU-TIP monitors the processing of this HEU at four Russian uranium-processing plants. During CY 2002, United States (U.S.) personnel monitored this process for a total of 194 monitor-weeks by staffing a Transparency Monitoring Office (TMO) located in Novouralsk, and through a series of five-day Special Monitoring Visits (SMV) to the four plants. U.S. monitor observations include the inventory of in-process containers, the observation of operations and non-destructive assay measurements (NDA) to determine 235 U enrichment, as well as the examination and validation of Russian Material Control and Accountability (MC and A) documents. In addition, the U.S. designed Blend Down Monitoring System (BDMS) installed at the Ural Electrochemical Integrated Plant (UEIP) in January 1999 monitored all HEU blended at that facility, which is about 50 percent of the HEU blended into LEU during CY 2002. Recently we installed a BDMS at the Electrochemical Plant (ECP) in Zelenogorsk and plans are underway to install a BDMS at the Siberian Chemical Enterprise (SChE) in Seversk in late 2004. On a very positive note, interpersonal interactions between U.S. and Russian technical experts continues to expand and have proven to be an important element of the transparency regime. On the tenth anniversary of the HEU Purchase Agreement, the Ministry of the R.F. for Atomic Energy (Minatom) also saluted the

    Just over five years ago, the Trilateral Initiative was launched to investigate the technical, legal and financial issues associated with IAEA verification of weapon-origin fissile material in the Russian Federation and the United States. Since then, the Joint Working Group has developed concepts and equipment suitable for such a verification mission, anticipating that the States would submit classified forms of fissile material to IAEA verification under new agreements developed for this purpose. This article summarizes the accomplishments to date and identifies the future steps foreseen under the Trilateral Initiative. As there is no legal commitment on the Parties to this Initiative as yet, the issues considered are still changing. Since it was launched, the Initiative has been given a sense of importance and weight, raising the expectations of the international community. The Final Document of the 2000 Conference on the Treaty on the Non-Proliferation of Nuclear Weapons (NPT), for example, under the review of Article VI of the Treaty, includes the statement to 'complete and implement the Trilateral Initiative'. It was launched following independent statements by the President of the United States beginning in 1993, and by the President of the Russian Federation in 1996. It is an Initiative between the IAEA, the Russian Federation and the United States that is in the context of Article VI of the NPT. The intention is to examine the technical, legal and financial issues associated with IAEA verification of weapon origin and other fissile material released from defense programmes in those two countries

    The metal-rich carbonaceous chondrites (CB and CH) have the highest whole-rock {sup 15}N enrichment ({delta}{sup 15}N up to +1500{per_thousand}), similar to {delta}{sup 15}N values reported in micron-sized regions (hotspots) of Interplanetary Dust Particles (IDPs) of possibly cometary origin and fine-grained matrices of unmetamorphosed chondrites. These {sup 15}N-rich hotspots are commonly attributed to low-temperature ion-molecule reactions in the protosolar molecular cloud or in the outer part of the protoplanetary disk. The nature of the whole-rock {sup 15}N enrichment of the metal-rich chondrites is not understood. We report a discovery of a unique type of primitive chondritic clasts in the CH/CB-like meteorite Isheyevo, which provides important constraints on the origin of {sup 15}N anomaly in metal-rich chondrites and nitrogen-isotope fractionation in the Solar System. These clasts contain tiny chondrules and refractory inclusions (5-15 {micro}m in size), and abundant ferromagnesian chondrule fragments (1-50 {micro}m in size) embedded in the partly hydrated, fine-grained matrix material composed of olivines, pyroxenes, poorly-organized aromatic organics, phyllosilicates and other hydrous phases. The mineralogy and oxygen isotope compositions of chondrules and refractory inclusions in the clasts are similar to those in the Isheyevo host, suggesting formation at similar heliocentric distances. In contrast to the previously known extraterrestrial samples, the fine-grained material in the clasts is highly and rather uniformly enriched in {sup 15}N, with bulk {delta}{sup 15}N values ranging between +1000 and +1300{per_thousand}; the {delta}{sup 15}N values in rare hotspots range from +1400 to +4000{per_thousand}. Since fine-grained matrices in the lithic clasts are the only component containing thermally unprocessed (during CAI and chondrule formation or during impact melting) materials that accreted into the metal rich chondrite parent body(ies), the {sup 15}N-enriched

The Russian texts of translations of Cochrane summaries and their main message were completely understandable or mostly clear to the vast majority of respondents (92%; n = 104). Respondents, proficient in English (n = 61), answered that the Russian-language translations fully complied (43%; n = 26) or in general corresponded to (57%; n = 35) the original English text. The majority of respondents (85%, n = 96) rated the quality of the translated texts as excellent and good. "More than half of respondents (61%; n = 69) would prefer the translations to be adapted to the usual style of presentation in Russian. The respondents agreed that mistakes, or typos or both very few. Our respondents provided valuable suggestions for further improvement of the Russian translations project. We would like to present here some of these: "More translations needed", "The ultimate goal... is to try to adapt the summaries to Russian language style as much as possible. This is a very challenging task, however and at present format the summaries are already great", "Go great as you do!" "Move forward and be efficient!" "Distribute information about the project through social networks and different means of social media", "Studying Cochrane Database should be included in the Russian medical school's curriculum at a much larger extent than it is included (if at all) now. It would be beneficial for high school students as well." The survey provided positive feedback on the Russian translations project concerning the clarity and quality of Russian texts and overall satisfaction of the readers. It confirmed the importance and relevance of the Russian translations project for Russian speaking audience, representing various professions and age groups. The survey results with detailed feedback contribute to further improvement of the Russian

    The US partners in the Laboratory-to-Laboratory Program in Nuclear Materials Protection, Control, and Accountability (MPC and A) have reached signed agreements with the Siberian Chemical Combine (SKhK) to rapidly enhance the protection, control, and accountability of nuclear material at all of its facilities. SKhK is the largest multi-function production center of the Russian nuclear complex and, until recently, its facilities produced and processed special nuclear materials for the Russian Defense Ministry. SKhK produces heat and electricity, enriches uranium for commercial reactor fuel, reprocesses irradiated fuel, and converts highly enriched uranium metal into oxide for blending into low-enriched reactor-grade uranium, and manufactures civilian products. SKhK is aggressively pursuing a program to enhance MPC and A which includes the installation of pedestrian and vehicle radiation monitors, rapid inventory methods, tamper-indicating devices, computerized accounting systems, and physical protection measures. This work is a collaboration between technical experts from Brookhaven, Lawrence Livermore, Los Alamos, Oak Ridge, pacific Northwest, and Sandia National Laboratories and their Russian counterparts at SKhK. This paper reviews the status of this initial effort and outlines plans for continuing the work in 1996

    For almost four years the United States (U.S), the Russian Federation (R.F.), and the International Atomic Energy Agency (IAEA) have been discussing an initiative to return Soviet/Russian-origin research reactor fuel to the Russian Federation. In a series of bilateral and trilateral meetings in Vienna and Moscow, considerable progress has been made toward defining the Russian Research Reactor Fuel Return Program as well as obtaining the necessary technical data to facilitate the return. More than 20 research reactors in 17 countries that have Soviet- or Russian-supplied fuel have identified. Most of these reactors have stocks of both fresh and irradiated HEU fuel that must be carefully stored and managed for many years to come. On September 21, 2003 the Russian Research Reactor Fuel Return program shipped 14 kg of fresh Russian-origin HEU fuel from Romania to the nuclear fuel fabrication facility in Russia, which represented the beginning of the practical implementation of the program.

    The objectives of this project were to convert the UMR Reactor fuel from high-enriched uranium (HEU) to low-enriched uranium (LEU) fuel and to ship the HEU fuel back to the Department of Energy Savannah River Site. The actual core conversion was completed in the summer of 1992. The HEU fuel was offloaded to an onsite storage pit where it remained until July, 1996. In July, 1996, the HEU fuel was shipped to the DOE Savannah River Site. The objectives of the project have been achieved. DOE provided the following funding for the project. Several papers were published regarding the conversion project and are listed in the Attachment. In retrospect, the conversion project required much more time and effort than originally thought. Several difficulties were encountered including the unavailability of a shipping cask for several years. The authors are grateful for the generous funding provided by DOE for this project but wish to point out that much of their efforts on the conversion project went unfunded

    Full Text Available The article analyzes the biography of Russian full general A.A. Brusilov − the hero of World War I, whose name is associated with the term “Brusilov Offensive”. The author exa-mines his views on the new situation which developed in Russia during the two revolutions of 1917, and then in the Soviet period. The author highly appreciates the theoretical preparation level of A.A. Brusilov, who got full military education in tsarist Russia; reveals the pre-sence of numerous analogous episodes in the biographies of A.A. Brusilov and A.V. Suvorov. He focuses on the similar origin of two Russian heroes, whose families belonged to the military dynasties of imperial Russia. The author concludes that the continuity of generations is very important in the issue of effective army’s functioning. This tradition was preserved in the new Soviet state.

  15. The origin of ICM enrichment in the outskirts of present-day galaxy clusters from cosmological hydrodynamical simulations

    The uniformity of the intracluster medium (ICM) enrichment level in the outskirts of nearby galaxy clusters suggests that chemical elements were deposited and widely spread into the intergalactic medium before the cluster formation. This observational evidence is supported by numerical findings from cosmological hydrodynamical simulations, as presented in Biffi et al., including the effect of thermal feedback from active galactic nuclei. Here, we further investigate this picture, by tracing back in time the spatial origin and metallicity evolution of the gas residing at z = 0 in the outskirts of simulated galaxy clusters. In these regions, we find a large distribution of iron abundances, including a component of highly enriched gas, already present at z = 2. At z > 1, the gas in the present-day outskirts was distributed over tens of virial radii from the main cluster and had been already enriched within high-redshift haloes. At z = 2, about 40 {per cent} of the most Fe-rich gas at z = 0 was not residing in any halo more massive than 10^{11} h^{-1} M_{⊙} in the region and yet its average iron abundance was already 0.4, w.r.t. the solar value by Anders & Grevesse. This confirms that the in situ enrichment of the ICM in the outskirts of present-day clusters does not play a significant role, and its uniform metal abundance is rather the consequence of the accretion of both low-metallicity and pre-enriched (at z > 2) gas, from the diffuse component and through merging substructures. These findings do not depend on the mass of the cluster nor on its core properties.

    During the January 1994 Summit Presidents Clinton and Yeltsin agreed on the goal of ensuring the ''transparency and irreversibility'' of the nuclear arms reduction process. As a result, negotiations are presently underway between the United States Government and the Russian Federation to confirm the stockpiles of plutonium and highly enriched uranium removed from nuclear weapons. In December 1994 the United States presented a paper to the Russian Federation proposing additional measures to provide broader transparency of nuclear arms reduction. The US Department of Energy is studying the implementation of these broader transparency measures at appropriate DOE facilities. The results of the studies include draft protocols for implementation, assessments of the implementation procedures and the impacts on the facilities and estimates of the cost to implement these measures at various facilities

    Deuterium-to-hydrogen (D/H) enrichments in molecular species provide clues about their original formation environment. The organic materials in primitive solar system bodies generally have higher D/H ratios and show greater D/H variation when compared to D/H in solar system water. We propose this difference arises at least in part due to (1) the availability of additional chemical fractionation pathways for organics beyond that for water, and (2) the higher volatility of key carbon reservoirs compared to oxygen. We test this hypothesis using detailed disk models, including a sophisticated, new disk ionization treatment with a low cosmic-ray ionization rate, and find that disk chemistry leads to higher deuterium enrichment in organics compared to water, helped especially by fractionation via the precursors CH2D+/CH3+. We also find that the D/H ratio in individual species varies significantly depending on their particular formation pathways. For example, from ˜20-40 au, CH4 can reach {{D}}/{{H}}˜ 2× {10}-3, while D/H in CH3OH remains locally unaltered. Finally, while the global organic D/H in our models can reproduce intermediately elevated D/H in the bulk hydrocarbon reservoir, our models are unable to reproduce the most deuterium-enriched organic materials in the solar system, and thus our model requires some inheritance from the cold interstellar medium from which the Sun formed.

    Full text: Russian Federation Minister of Atomic Energy Alexander Rumyantsev, United States Secretary of Energy Spencer Abraham and Director General of the International Atomic Energy Agency (IAEA) Mohamed ElBaradei met in Vienna on 16 September 2002 to review the status of the Trilateral Initiative and agree on its future direction. The parties concluded that the task entrusted to the Trilateral Initiative Working Group in 1996 has been fulfilled. The work completed has demonstrated practical approaches for IAEA verification of weapon-origin fissile material designated as released from defence programmes in classified forms or at certain sensitive facilities. The work included the examination of technical, legal and financial issues associated with such verification. The removal of weapon-origin fissile material from defence programmes of the Russian Federation and the United States is in furtherance of the commitment to disarmament steps undertaken by the two States pursuant to Article VI of the Treaty on the Non-Proliferation of Nuclear Weapons (NPT). IAEA verification of the materials declared excess to nuclear weapons programmes and made subject to this Initiative would build international confidence that this material will never again be used in nuclear weapons. Minister Rumyantsev, Secretary Abraham and Director General ElBaradei recognized the value of the groundbreaking work completed over the last six years. Building on the work completed, they directed the technical experts to begin without delay discussions on future possible cooperation within the trilateral format. Minister Rumyantsev, Secretary Abraham and Director General ElBaradei agreed that the Principals would meet again in September 2003 to review progress within the trilateral format. (IAEA)

  19. Considering the post-1995 enrichment market

    1994-01-01

    World demand for uranium enrichment services is likely to grow only a little over the next decade, from the current 28 million separative work units (SWU) per year to 33 MSWU per year. Much of the growth will come from Asia where nuclear generating capacity is still increasing. The current situation of the primary enrichment companies is summarized. The primary Western suppliers, Cogema, United States Enrichment Corporation and Urenco, are competing for increased market share in the USA, Europe and Asia as utilities purchase their post-1995 requirements. Entry of the Russian enrichment company, Tenex, into Western markets has been limited by trade restrictions. As a consequence of disarmament, blended weapons material has resulted in a surplus of low-enriched uranium. Together with over-capacity amongst the primary enrichers this has led to an expectation that reduced prices will be negotiable in the medium term. (3 figures). (UK)

    The Russian program started at the end of 70's. The final goal of the program was to minimize and in perspective to eliminate using of HEU in fuel elements and assemblies supplied to foreign research reactors with the minimum of penalties for the experimenters. Later officials, scientists and engineers began political and scientific discussion about reducing enrichment domestic reactors as well as return of fresh and spent HEU fuel. Important issues of the Russian program is concerned with cooperation with USA, especially related to new types of LEU fuel elements development and fabrication to be used in Russian designed foreign research reactors. According to present results this goal will be achieved by 2006

    Full Text Available The aim of this paper is to investigate the attractiveness of Bucharest and its perception by Russian tourists as well as to examine the strengths and weaknesses of the city and define the idea for positioning statement for this place. Bucharest has a deep history and cultural heritage that are highly appreciated by tourists seeking cultural tourism. Moreover, Bucharest had the nickname of "Little Paris" which implied the beauty of the city. Our study focuses mainly on the target audience of Russian people who appreciate cultural heritage. According to the Russian Federal State Statistics Service (Rosstat, the number of Russians who visited Romania as tourists increased by 73% in the first quarter of 2015 (http://russtd.com/destinations/eastern-europe-loses-almost-half-russian-tourists-year. This increase is a positive sign as it means that Romania and Bucharest are becoming more and more attractive for Russian tourists. Tourists can bring many benefits to the place, both economic and social. In turn, new places with heritage can enrich tourists with new knowledge and broaden their erudition. The study allows us to understand the perception of Bucharest by Russian tourists and single out the key elements of the city of Bucharest. The key elements of the city of Bucharest are rooted in cultural heritage and authenticity, including different styles of architecture, Orthodox churches, classical and folk music, outstanding musicians and food. Bucharest might thus be offered the positioning as a mysterious authentic city revealing the coexistence of different times.To some extent this paper contributes to the understanding of the image of Bucharest in Russian tourists’ eyes, their associations and fears. It gives some insights into factors that make Russians choose touristic destinations. In addition, some ideas for the city positioning, logos and slogans can derive from this paper. The study can be useful for touristic agencies or for the Ministry

  2. Supply of low enriched (LEU) and highly enriched uranium (HEU) for research reactors

    Enriched uranium for research reactors in the form of LEU /= low enriched uranium at 19.75% U-235) and HEU (= highly enriched uranium at 90 to 93% U-235) was and is - due to its high U-235 enrichment - a political fuel other than enriched uranium for power reactors. The sufficient availability of LEU and HEU is a vital question for research reactors, especially in Europe, in order to perform their peaceful research reactor programs. In the past the USA were in the Western hemisphere sole supplier of LEU and HEU. Today the USA have de facto stopped the supply of LEU and HEU, for HEU mainly due to political reasons. This paper deals, among others, with the present availability of LEU and HEU for European research reactors and touches the following topics: - historical US supplies, - influence of the RERTR-program, - characteristics of LEU and HEU, - military HEU enters the civil market, -what is the supply situation for LEU and HEU today? - outlook for safe supplies of LEU and HEU.

    2002-01-01

    The Australian Nuclear Science and Technology Organisation (ANSTO) operates the High Flux Australian Reactor (HIFAR). HIFAR commenced operation in the late 1950's with fuel elements containing uranium enriched to 93%. From that time the level of enrichment has gradually decreased to the current level of 60%. It is now proposed to further reduce the enrichment of HIFAR fuel to <20% by utilising LEU fuel assemblies manufactured by RISO National Laboratory, that were originally intended for use in the DR-3 reactor. Minor modifications have been made to the assemblies to adapt them for use in HIFAR. A detailed design review has been performed and initial safety analysis and reactor physics calculations are to be submitted to ARPANSA as part of a four-stage approval process. (author)

    Travelli, A.

    1994-01-01

    The goal of the RERTR program is to minimize and eventually eliminate use of highway enriched uranium (HEU) in research and test reactors. The program has been very successful, and has developed low-enriched uranium (LEU) fuel materials and designs which can be used effectively in approximately 90 percent of the research and test reactors which used HEU when the program began. This progress would not have been possible without active international cooperation among fuel developers, commercial vendors, and reactor operators. The new tasks which the RERTR program is undertaking at this time include development of new and better fuels that will allow use of LEU fuels in all research and test reactors; cooperation with Russian laboratories, which will make it possible to minimize and eventually eliminate use of HEU in research reactors throughout the world, irrespective of its origin; and development of an LEU-based process for the production of 99 Mo. Continuation and intensification of international cooperation are essential to the achievement of the ultimate goals of the RERTR program

    We studied the differences in the mean pre-pregnancy body mass index (BMI) and mean inter-pregnancy weight change in women of Russian, Somali and Kurdish origin and women in the general Finnish population. The population-based samples were from the Migrant Health and Wellbeing Study and the Health 2011 Survey conducted in six cities in Finland in 2010-2012. This study included women with at least one birth in Finland. Data on their previous pregnancies in Finland were obtained from the National Medical Birth Register for 318 Russian, 584 Somali and 373 Kurdish origin women and for 243 women in the general Finnish population (reference group). Data on pre-pregnancy weight and height were self-reported in early pregnancy. Linear logistic regression was the main method of analysis. The unadjusted mean pre-pregnancy BMI was higher in Somali (27.0 kg/m 2 , p<0.001) and Kurdish (25.8 kg/m 2 , p<0.001) women, but lower in Russian (22.2 kg/m 2 , p<0.001) women than in the reference group (24.1 kg/m 2 ). The adjusted coefficients for the difference in the mean pre-pregnancy BMI were -1.93 (95% CI -2.77 to -1.09) for Russian, 1.82 (95% CI 0.89-2.75) for Somali and 1.30 (95% CI 0.43-2.17) for Kurdish women compared with the reference group. Among women with at least two births, no statistically significant difference was observed in the mean inter-pregnancy weight change between the migrant groups and the reference group. Somali and Kurdish women had higher mean pre-pregnancy BMIs than women in the general Finnish population and may need special support and health promotion strategies for weight management.

    In the process of spent nuclear fuel (SNF) returning from Armenia, Bulgaria, Hungary, Slovakia, Ukraine, Finland and the Czech Republic to the Russian Federation the following issues have to be considered: 1) Does the legal opportunity of SNF import to the RF exist? 2) Does the technical opportunity for SNF acceptance at reprocessing or disposal facility exist? 3) What are the basic conditions for SNF import? 4) What are the basic conditions for return or retaining of reprocessing products including RAW? The first issue is a legal one and has to be resolved within the framework of federal laws, RF government regulations and international agreements. The second issue is normative-technical. It is regulated by documents of Rostechnadzor (Federal agency on ecological, technological and nuclear supervision), federal norms and regulations in the field of atomic energy usage, industry standards, and in case they are absent, by technical specifications for SNF supply. The last two issues are resolved in the process of drafting foreign trade contracts on SNF import. Generally, Russian regulatory framework is developed enough to regulate SNF import and handling, even in most complicated cases. Nevertheless, when foreign trade contracts on SNF import being drafted there may be disputed regarding both SNF import and RAW return. This report concerns the RF legal and regulatory basis on terms and conditions of SNF import, interim storage, reprocessing and reprocessing products handling in the RF. (authors)

  10. Overview of the Russian nuclear industry

    International Nuclear Information System (INIS)

    2008-02-01

    In 2004, President Poutine decided to replace the atomic energy ministry (Minatom) by the federal atomic energy agency (Rosatom). Several projects were launched during the next two years which aimed at bringing back Russia to the fore front of the world leaders of nuclear energy use and nuclear technology export. In 2007, Rosatom agency was changed to a public holding company and a new company, named Atomenergoprom, was created which gathers all civil nuclear companies (AtomEnergoMash for the exploitation of power plants, Technabsexport (Tenex) specialized in enrichment or Atomstryexport in charge of export activities). Thus, Rosatom is at the head of all civilian and military nuclear companies, of all research centers, and of all nuclear and radiological safety facilities. In 2006, Russian nuclear power plants supplied 15.8% of the whole power consumption. Russia wishes to develop its nuclear program with the construction of new reactors in order to reach a nuclear electricity share of 25% from now to 2020. This paper presents first the 2007 institutional reform of the Russian atomic sector, and the three sectorial federal programmes: 1 - development of the nuclear energy industrial complex for the 2007-2010 era and up to 2015 (future power plants, nuclear fuel centers and reactor prototypes), 2 - nuclear safety and radioprotection for the 2008-2015 era (waste management, remedial actions, radiation protection), 3 - military program (confidential). Then, the paper presents: the international actions (export of Russian technology, cooperation agreements, non-proliferation), the situation of the existing nuclear park (reactors in operation, stopped, under construction and in project), the fuel cycle activities (production of natural uranium, enrichment, fuel fabrication, spent fuel storage, reprocessing, waste management), the nuclear R and D in Russia, and the nuclear safety authority.

  12. Disposition of surplus highly enriched uranium: Draft environmental impact statement

    International Nuclear Information System (INIS)

    1995-10-01

    This document assesses the environmental impacts at four potential sites that may result from alternatives for the disposition of United States-origin weapons-usable highly enriched uranium (HEU) that has been or may be declared surplus to national defense or defense-related program needs. In addition to the no action alternative, it assesses four alternatives that would eliminate the weapons-usability of HEU by blending it with depleted uranium, natural uranium, or low-enriched uranium (LEU) to create low-enriched uranium, either as commercial reactor fuel feedstock or as low-level radioactive waste. The potential blending sites are DOE's Y-12 Plant at Oak Ridge Reservation in Oak Ridge, Tennessee; DOE's Savannah River Site in Aiken, South Carolina; the Babcock ampersand Wilcox Naval Nuclear Fuel Division Facility in Lynchburg, Virginia; and the Nuclear Fuel Services Fuel Fabrication Plant in Erwin, Tennessee. Evaluations of impacts on site infrastructure, water resources, air quality and noise, socioeconomic resources, waste management, public and occupational health, and environmental justice for the potential blending sites are included in the assessment. The intersite transportation of nuclear and hazardous materials is also assessed. The preferred alternative is to blend down surplus HEU to LEU for maximum commercial use as reactor fuel feed which would likely be done at a combination of DOE and commercial sites

    To elucidate the possible interaction mechanisms between DAG-enriched oils, this study investigated how mixtures of DAG-enriched palm-based oils influenced the phase behavior, thermal properties, crystallization behaviors and the microstructure in binary fat blends. DAG-enriched palm oil (PO-DAGE) was blended with DAG-enriched palm olein (POL-DAGE) in various percentages (0%, 10%, 30%, 50%, 70%, 90%, 100%). Based on the observation of iso-solid diagram and phase diagram, the binary mixture of PO-DAGE/POL-DAGE showed a better compatibility in comparison with their corresponding original blends. DSC thermal profiles exhibited that the melting and crystallization properties of PO-DAGE/POL-DAGE were distinctively different from corresponding original blends. Crystallization kinetics revealed that PO-DAGE/POL-DAGE blends displayed a rather high crystallization rate and exhibited no spherulitic crystal growth. From the results of polarized light micrographs, PO-DAGE/POL-DAGE blends showed more dense structure with very small needle-like crystals than PO/POL. X-ray diffraction evaluation revealed when POL-DAGE was added in high contents to PO-DAGE, above 30%, β-polymorph dominated, and the mount of β' forms crystals was decreasing.

  14. Conversion of research and test reactors to low enriched uranium fuel: technical overview and program status

    International Nuclear Information System (INIS)

    Roglans-Ribas, J.

    2008-01-01

    Many of the nuclear research and test reactors worldwide operate with high enriched uranium fuel. In response to worries over the potential use of HEU from research reactors in nuclear weapons, the U.S Department of Energy (DOE) initiated a program - the Reduced Enrichment for Research and Test Reactors (RERTR) - in 1978 to develop the technology necessary to reduce the use of HEU fuel by converting research reactors to low enriched uranium (LEU) fuel. The Reactor Conversion program is currently under the DOE's National Nuclear Security Administration's Global Threat Reduction Initiative (GTRI). 55 of the 129 reactors included in the scope have been already converted to LEU fuel or have shutdown prior to conversion. The major technical activities of the Conversion Program include: (1) the development of advanced LEU fuels; (2) conversion analysis and conversion support; and (3) technology development for the production of Molybdenum-99 (Mo 99 ) with LEU targets. The paper provides an overview of the status of the program, the technical challenges and accomplishments, and the role of international collaborations in the accomplishment of the Conversion Program objectives. Nuclear research and test reactors worldwide have been in operation for over 60 years. Many of these facilities operate with high enriched uranium fuel. In response to increased worries over the potential use of HEU from research reactors in the manufacturing of nuclear weapons, the U.S Department of Energy (DOE) initiated a program - the Reduced Enrichment for Research and Test Reactors (RERTR) - in 1978 to develop the technology necessary to reduce the use of HEU fuel in research reactors by converting them to low enriched uranium (LEU) fuel. The reactor conversion program was initially focused on U.S.-supplied reactors, but in the early 1990s it expanded and began to collaborate with Russian institutes with the objective of converting Russian supplied reactors to the use of LEU fuel.

    In January 1998 the United States Enrichment Corporation (USEC) and Techsnabexport Co., Ltd (TENEX) of Russia celebrated the fourth anniversary of the signing of the 20-year contract between these two executive agents. USEC and TENEX are responsible for implementing the Government to-Government agreement between the United States and the Russian Federation for the purchase of uranium derived from dismantled nuclear weapons from the former Soviet Union. This program, entitled 'Megatons to Megawatts', is the first time nuclear warheads have been turned into fuel as well as the first time a commercial contract has been used to implement such a program. As of the fourth anniversary, the equivalent of almost 1,200 nuclear warheads had been converted to fuel. USEC is responsible for making all of the arrangements to transport the Russian LEU derived from HEU--hence the term, derived enriched uranium (DEU)--from St Petersburg. Russia to the USEC plant near portsmouth, Ohio. Edlow International Company is working with USEC to implement the shipping campaign and is responsible for coordination of the port delivery within Russia, as well. The organization responsible for these shipments within Russia is IZOTOP. While the program has been a major new responsibility for USEC, the early years of the program prepared all parties for the future challenges such as increased numbers of shipments, additional originating sites in Russia and witnessing requirements in Russia.

  16. Origin of middle rare earth element enrichments in acid waters of a Canadian high Arctic lake.

    1999-01-01

    -Middle rare earth element (MREE) enriched rock-normalized rare earth element (REE) patterns of a dilute acidic lake (Colour Lake) in the Canadian High Arctic, were investigated by quantifying whole-rock REE concentrations of rock samples collected from the catchment basin, as well as determining the acid leachable REE fraction of these rocks. An aliquot of each rock sample was leached with 1 N HNO 3 to examine the readily leachable REE fraction of each rock, and an additional aliquot was leached with a 0.04 M NH 2OH · HCl in 25% (v/v) CH 3COOH solution, designed specifically to reduce Fe-Mn oxides/oxyhydroxides. Rare earth elements associated with the leachates that reacted with clastic sedimentary rock samples containing petrographically identifiable Fe-Mn oxide/oxyhydroxide cements and/or minerals/amorphous phases, exhibited whole-rock-normalized REE patterns similar to the lake waters, whereas whole-rock-normalized leachates from mafic igneous rocks and other clastic sedimentary rocks from the catchment basin differed substantially from the lake waters. The whole-rock, leachates, and lake water REE data support acid leaching or dissolution of MREE enriched Fe-Mn oxides/oxyhydroxides contained and identified within some of the catchment basin sedimentary rocks as the likely source of the unique lake water REE patterns. Solution complexation modelling of the REEs in the inflow streams and lake waters indicate that free metal ions (e.g., Ln 3+, where Ln = any REE) and sulfate complexes (LnSO 4+) are the dominant forms of dissolved REEs. Consequently, solution complexation reactions involving the REEs during weathering, transport to the lake, or within the lake, cannot be invoked to explain the MREE enrichments observed in the lake waters.

  17. The Wassenaar Arrangement and Russian High-Tech Export

    Directory of Open Access Journals (Sweden)

    Lilia S. Revenko

    2016-01-01

    Full Text Available The current military and political situation in the world raises the necessity of use by Russia of all existing tools to counter actions targeted against it. Participation of the country in international export control regimes, including the Wassenaar Arrangement (the WA, is one of these tools. Membership in the WA allows to Russia to maintain its international status, to contribute to strengthening of international stability, to ensure the non-targeting of this forum against the country, to participate in the development of decisions affecting its interests. Participation in the WA is also important from the view of modernizations of Russian economy towards transition to a new technological mode accompanied by emergence of new groups of innovative products and modification of existing ones. Control of crossing the country's borders by dual-use goods and services is one of conditions for carrying out their export. The Wassenaar Arrangement was established in 1995 to replace COCOM in order to contribute to regional and international security and stability. A huge work is carried out within the forum aimed at enhancing control over transfers of conventional weapons and high-tech dual-use goods. Russian export control system fully meets requirements of international export control regime, including the WA, and effectively functions. Export of the controlled goods from Russia or their transfer to foreign individuals and legal entities are possible only on the basis of decisions of the Export control Commission of the Russian Federation. The dilemma between the need to support exporters by reducing administrative barriers and the ensuring security interests of the country gain momentum in current stage of scientific-and-technological advance development.

    We evaluated the consumption of healthy foods among Russian, Somali and Kurdish immigrants in Finland, and examined the relationship between socio-demographic factors and food consumption. We used data from the Migrant Health and Wellbeing Study (Maamu), a population-based health interview and examination survey in six different municipalities in Finland between 2010 and 2012. Altogether, 635 men and 737 women, aged 18-64 years, of Russian ( n = 527), Somali ( n = 337) and Kurdish ( n = 508) origin were included. The important socio-demographic determinants of healthy food consumption - sex, age, education, place of residence and household size - were assessed by logistic regression. Based on the consumption frequencies of recommended healthy foods - fruits, berries, vegetables, fish and rye bread - immigrants of Russian origin had higher consumption of healthy foods than their peers of Kurdish and Somali origin. Low consumption of fresh vegetables, fruits and berries was found among Somali immigrants. Sex and age were the most important determinants of healthy food consumption, as women and older age groups had diets closer to the national nutrition recommendations. High educational level was also positively associated with healthy food consumption. We found ethnic differences in the consumption of healthy foods among the immigrant groups of Russian, Somali and Kurdish origin in Finland. Socio-demographic factors, especially age, sex and education, seem to also play an important role in immigrants' food consumption. Further studies examining the consumption of fruits, berries and fresh vegetables among Somali immigrants in Finland are needed.

    2010-12-01

    The unique nature of Israeli society as an immigrant society has also affected the prison population in Israel. This article focuses on a social and cultural phenomenon that particularly characterizes the prisoners of Russian origin, the phenomenon of tattoos. Using postmodernist theories, the article examines the function of the tattoo among Russian prisoners and the role it plays in constructing the criminal self-identity of these inmates in Israeli prisons. The tattoos observed during 2005-2006 among the Russian prisoners in four major Israeli prisons reflect the values of the Russian criminal subculture from which they evolved and were imported. This subculture is characterized by a hierarchical class structure and manifestations of machismo, domination, defiance, rebellion, and open antagonism against the Establishment and its representatives.

    1987-01-01

    Twelve clones of origin-enriched sequences (ORS) isolated from early replicating monkey (CV-1) DNA were examined for transient episomal replication in transfected CV-1, COS-7, and HeLa cells. Plasmid DNA was isolated at time intervals after transfection and screened by the Dpn I resistance assay or by the bromodeoxyuridine substitution assay to differentiate between input and replicated DNA. The authors have identified four monkey ORS (ORS3, -8, -9, and -12) that can support plasmid replication in mammalian cells. This replication is carried out in a controlled and semiconservative manner characteristic of mammalian replicons. ORS replication was most efficient in HeLa cells. Electron microscopy showed ORS8 and ORS12 plasmids of the correct size with replication bubbles. Using a unique restriction site in ORS12, we have mapped the replication bubble within the monkey DNA sequence

  5. Active interrogation of highly enriched uranium

    Science.gov (United States)

    Fairrow, Nannette Lea

    Safeguarding special nuclear material (SNM) in the Department of Energy Complex is vital to the national security of the United States. Active and passive nondestructive assays are used to confirm the presence of SNM in various configurations ranging from waste to nuclear weapons. Confirmation measurements for nuclear weapons are more challenging because the design complicates the detection of a distinct signal for highly enriched uranium. The emphasis of this dissertation was to investigate a new nondestructive assay technique that provides an independent and distinct signal to confirm the presence of highly enriched uranium (HEU). Once completed and tested this assay method could be applied to confirmation measurements of nuclear weapons. The new system uses a 14-MeV neutron source for interrogation and records the arrival time of neutrons between the pulses with a high efficiency detection system. The data is then analyzed by the Feynman reduced variance method. The analysis determined the amount of correlation in the data and provided a unique signature of correlated fission neutrons. Measurements of HEU spheres were conducted at Los Alamos with the new system. Then, Monte Carlo calculations were performed to verify hypothesis made about the behavior of the neutrons in the experiment. Comparisons of calculated counting rates by the Monte Carlo N-Particle Transport Code (MCNP) were made with the experimental data to confirm that the measured response reflected the desired behavior of neutron interactions in the highly enriched uranium. In addition, MCNP calculations of the delayed neutron build-up were compared with the measured data. Based on the results obtained from this dissertation, this measurement method has the potential to be expanded to include mass determinations of highly enriched uranium. Although many safeguards techniques exist for measuring special nuclear material, the number of assays that can be used to confirm HEU in shielded systems is

    Since 1992, the All-Russian Scientific Research Institute of Experimental Physics and the Los Alamos National Laboratory, the institutes that designed the first nuclear weapons of the Soviet Union and the US, respectively, have been working together in fundamental research related to pulsed power and high energy density science. This collaboration has enabled scientists formerly engaged in weapons activities to redirect their attention to peaceful pursuits of wide benefit to the technical community. More than thirty joint experiments have been performed at Sarov and Los Alamos in areas as diverse as solid state physics in high magnetic fields, fusion plasma formation, isentropic compression of noble gases, and explosively driven-high current generation technology. Expanding on the introductory comments of the conference plenary presentation, this paper traces the origins of this collaboration and briefly reviews the scientific accomplishments. Detailed reports of the scientific accomplishments can be found in other papers in these proceedings and in other publications

  7. Richard III in Russian Theatre at the Twilight of the "Thaw"

    OpenAIRE

    Sokolyansky, Mark

    2007-01-01

    Richard III was very rarely staged in Russian theatre in tsarist and Stalin’s times, because the story of inhuman tyranny provoked associations with Russian political reality. In the period of the so-called “Thaw” (1954ß1964) the play became very popular in the USSR and several scenic productions of it were real events in Russian (and Soviet) theatrical life. In the essay three most original and successful performances (in Kujbyshev, Gorkij and Erevan) are discussed and compare...

    2017-03-01

    Full Text Available In his essay “The Russians on Capri” (1924, a Russian journalist Mikhail Pervukhin describes the discovery of Capri by Russian artists and writers before the events of 1905 and the development of the Russian colony on the island afterwards. Pervukhin relates the origin and the history of the Russian colony on Capri to the period from 1906 through 1913, when the island became a residence of Russian political immigrants. He sees Gorky’s arrival on Capri as a major catalyzer in the development of the colony due to the defining and formative nature of the political and literary activity of the latter. The Russian revolution of 1905 had radically changed the structure of the Russian population on Capri: since that time it mostly consisted of political refugees. Pervukhin’s evidence is one of the most important documents on Gorky’s reception in Italy. Pervukhin left documentary and artistic evidence of Gorky’s residence on the island written with a special focus on Gorky’s role in the Russian Revolution of 1917 and its critical reconsideration. The author emphasized the political component in the life of the colony. He criticized activities of the Capri school for workers founded by Gorky and Lunacharsky. According to Pervukhin, Russian revolutionaries were indifferent to the beauty of the island and to the “eternal” values swept away by the storm of the October Revolution.

    The United States of America is the world's largest market for uranium enrichment services. After the disintegration of the Soviet Union, Russian uranium is entering the world market on an increasing scale. The U.S. tries to protect its market and, in this connection, also the European market from excessive price drops by taking anti-dumping measures. In order to become more competitive, American companies have adapted modern enrichment techniques from Europe. European - U.S. joint ventures are to help, also technically and economically, to integrate military uranium, accumulating as a consequence of worldwide disarmament, into the commercial fuel cycle for the peaceful use of nuclear power.

    This study is of an exploratory nature. It provides preliminary assessments of issues of relevance for HEU elimination in Russia including: (a) technical issues concerning the HEU down-blending; uranium transparency and verification requirements; description of current Russian HEU locations; the HEU down-blending capacities, and the HEU logistics, and (b) various political and financial requirements and considerations. For future, practical project measures to be put in place, further investigations that deal with HEU logistics and handling are needed. Such studies - that obviously should include and engage key Russian actors - are possible, if they take legitimate Russian security and sensitivity concerns into consideration. Interestingly, there is a growing perception in Russia that large stocks of HEU are not required and that they could, in fact, constitute a source of danger

    Ewing's sarcoma is a highly malignant bone tumor found in children and adolescents, and the origin of this malignancy is not well understood. Here, we introduced a Ewing's sarcoma-associated genetic fusion of the genes encoding the RNA-binding protein EWS and the transcription factor ETS (EWS-ETS) into a fraction of cells enriched for osteochondrogenic progenitors derived from the embryonic superficial zone (eSZ) of long bones collected from late gestational murine embryos. EWS-ETS fusions efficiently induced Ewing's sarcoma-like small round cell sarcoma formation by these cells. Analysis of the eSZ revealed a fraction of a precursor cells that express growth/differentiation factor 5 (Gdf5), the transcription factor Erg, and parathyroid hormone-like hormone (Pthlh), and selection of the Pthlh-positive fraction alone further enhanced EWS-ETS-dependent tumor induction. Genes downstream of the EWS-ETS fusion protein were quite transcriptionally active in eSZ cells, especially in regions in which the chromatin structure of the ETS-responsive locus was open. Inhibition of β-catenin, poly (ADP-ribose) polymerase 1 (PARP1), or enhancer of zeste homolog 2 (EZH2) suppressed cell growth in a murine model of Ewing's sarcoma, suggesting the utility of the current system as a preclinical model. These results indicate that eSZ cells are highly enriched in precursors to Ewing's sarcoma and provide clues to the histogenesis of Ewing's sarcoma in bone.

    Efficient glycopeptides enrichment prior to mass spectrometry analysis is essential for glycoproteome study. ZIC-HILIC (zwitterionic hydrophilic interaction liquid chromatography) based glycopeptides enrichment approaches have been attracting more attention for several benefits like easy operating, high enrichment specificity and intact glycopeptide retained. In this study, Poly (amidoamine) dendrimer (PAMAM) was adopted for the synthesis of zwitterionically functionalized (ZICF) materials for glycopeptide enrichment. The multiple branched structure and good solubility of ZICF-PAMAM enables a sufficient interaction with glycopeptides. The ZICF-PAMAM combined with the FASP-mode enrichment strategy exhibits more superior performance compared with the existing methods. It has the minimum detectable concentration of femtomolar level and high recovery rate of over 90.01%, and can efficiently enrich glycopeptides from complex biological samples even for merely 0.1 μL human serum. The remarkable glycopeptides enrichment capacity of ZICF-PAMAM highlights the potential application in in-depth glycoproteome research, which may open up new opportunities for the development of glycoproteomics.

    The research reactors, of which the fuel elements are of MTR type, functions presently, almost in their majority with high U-235 enrichment. The fear that those fuel elements might generate a considerabLe proliferation of nuclear weapons rendered almost mandatory the conversion of highly enriched fuel elements to a low U-235 enrichment. As the IEA-R1 reactor of IPEN is operating with highly enriched fuel elements a study aiming at this conversion was done. The problems related to the conversion and the results obtained, demonstrated the technical viabilty for its realization. (E.G.) [pt

    Development and attestation of gamma-ray non-destructive assay measurement methodologies for use by inspectors of the Russian Federal Service for Environmental, Technological, and Nuclear Oversight (Rostekhnadzor, formerly Gosatomnadzor or GAN), as well as for use by Russian nuclear facilities, has been completed. Specifically, a methodology utilizing the gamma-ray multi group analysis (MGA) method for determining plutonium isotopic composition has been developed, while existing methodologies to determining uranium enrichment and isotopic composition have been revised to make them more appropriate to the material types and conditions present in nuclear facilities in the Russian Federation. This paper will discuss the development and revision of these methodologies, the metrological characteristics of the final methodologies, as well as the limitations and concerns specific to the utilization of these analysis methods in the Russian Federation

    2010-01-01

    Under the auspices of the Global Threat Reduction Initiative Reduced Enrichment for Research and Test Reactors Program, the National Nuclear Security Administration/Department of Energy (NNSA/DOE) has, as a goal, to convert research reactors worldwide from weapons grade to non-weapons grade uranium. The High Flux Isotope Reactor (HFIR) at Oak Ridge National Lab (ORNL) is one of the candidates for conversion of fuel from high enriched uranium (HEU) to low enriched uranium (LEU). A well documented business model, including tasks, costs, and schedules was developed to plan the conversion of HFIR. Using Microsoft Project, a detailed outline of the conversion program was established and consists of LEU fuel design activities, a fresh fuel shipping cask, improvements to the HFIR reactor building, and spent fuel operations. Current-value costs total $76 million dollars, include over 100 subtasks, and will take over 10 years to complete. The model and schedule follows the path of the fuel from receipt from fuel fabricator to delivery to spent fuel storage and illustrates the duration, start, and completion dates of each subtask to be completed. Assumptions that form the basis of the cost estimate have significant impact on cost and schedule.

    2011-01-01

    Full Text Available In the second part of the text about the Filofei’s doctrine of “Moscow, Third Rome,” the author deals with its reception in later periods of Russian intellectual and political history. Although this doctrine in its original form had no explicit imperial or foreign-political connotation, this paper analyzes the interpretations of the “Third Rome idea” that had significant political consequences. Internally, this idea was used by Prince Kurbskii for the criticism of Ivan the Terrible’s politics (XVI Century, as well as the rejection of the church reforms of Patriarch Nikon in the Old Believers’ literature (XVII Century. However, the revival of interest in the idea of the “Third Rome” characterized the Russian nineteenth century when the discussions on the relationship between Russia and the West emerged. Criticizing the reforms by Peter the Great, the classical Slavophiles found confirmation of the Russian cultural originality and superiority in the past of traditional Muscovy. The author highlights the differences between religious-philosophical and geopolitical interpretations of Russian messianism in the works of Russian Slavophiles and Panslavs. In the final section of this article, Russian messianic ideas are put in a relation with the birth of nationalism in the context of the Russian Empire. In this way, the author’s findings call into question the widespread interpretation of the “Third Rome messianism” as a distinctive and exceptional Russian characteristic.

    MNEs actively promote a mix of global best practices and local HRM practices. We do not find any instances of the reverse transfer of management practices from subsidiaries in developed countries to the MNEs' headquarters or any examples of cross-pollination among subsidiaries.......This article analyzes variations in the international human resource management ( IHRM) approaches of Russian multinational enterprises ( MNEs) in the contexts of developed and developing countries. The data were gathered through interviews conducted at the headquarters of Russian MNEs...... and at their subsidiaries in developed and developing countries. The results indicate that Russian MNEs adopt HRM practices of Western origin. However, these MNEs differ radically in their choices of IHRM approaches. Many of these differences depend on the countries these MNEs target in their international expansion...

    The article considers the economic aspects of constructing high-rise buildings in the world and in Russia. Data on the number of high-rise buildings in Russian cities with a million population are presented. It is proved that interest in high-rise construction in Russia has been formed only in Moscow and partly in St. Petersburg and Yekaterinburg. The analysis showed that the reason for this is the expensiveness of high-rise construction. According to the enlarged macro-calculation, the cost of building 1 m2 of the area of the Federation Towers complex (Moscow City) is about 2710 /m2. Practically a possibility of return on investments in the foreseeable time interval exists only in Moscow. For the regions of Russia this task is rather complicated. Population density in regional Russian cities is quite low, business entities do not have the necessary financial resources for investing in high-rise construction, and investments from abroad absent.

    2014-01-01

    Full Text Available The article analyses the image of a scientist represented in recent Russian movies. The article discusses two groups of questions: (1 nature and role of popular science in the life of society; (2 national features of scientific cultures. The article agues that popular science should not be conceived as a week copy of the real science. On the contrary, modern models of science communication assume that popular science have its own value and is able to influence scientific practices. Simultaneously we assume, that since popular science is less integrated with international scientific norms, it can easer reveal national traditions of scientific life. As a result, the analyze of recent Russian movies shows that the tradition established in Peter I times for Russian scientists to work out their self-identity in concern with Russian state still exists (scientist- state supporter/scientist- oppositionist. Actually the modern interpretation of dilemma between state patriotism and liberalism given by modern movies shows that Russian scientist don't have real choice, because they loose anyway whereas the state always wins. So owing to recent movies this representation of hopeless destiny of a scientist is becoming widespread in Russian public culture.

    2003-01-01

    This paper presents a criticality evaluation of moderated homogeneous plutonium-uranium mixtures. The fissile media studied are homogeneous mixtures of plutonium and high enriched uranium in two chemical forms: aqueous mixtures of metal and mixtures of nitrate solutions. The enrichment of uranium considered are 93.2wt.% 235 U and 100wt.% 235 U. The 240 Pu content in plutonium varies from 0wt.% 240 Pu to 12wt.% 240 Pu. The critical parameters (radii and masses of a 20 cm water reflected sphere) are calculated with the French criticality safety package CRISTAL V0. The comparison of the calculated critical parameters as a function of the moderator-to-fuel atomic ratio shows significant ranges in which high enriched uranium systems, as well as plutonium-uranium mixtures, are more reactive than plutonium systems.

    1993-01-01

    After almost 40 years of operation, the federal government is withdrawing from the uranium enrichment business. On July 1, the Department of Energy turned over to a new government-owned entity--the US Enrichment Corp. (USEC)--both the DOE enrichment plants at Paducah, Ky., and Portsmouth, Ohio, and domestic and international marketing of enriched uranium from them. Pushed by the inability of DOE's enrichment operations to meet foreign competition, Congress established USEC under the National Energy Policy Act of 1992, envisioning the new corporation as the first step to full privatization. With gross revenues of $1.5 billion in fiscal 1992, USEC would rank 275th on the Fortune 500 list of top US companies. USEC will lease from DOE the Paducah and Portsmouth facilities, built in the early 1950s, which use the gaseous diffusion process for uranium enrichment. USEC's stock is held by the US Treasury, to which it will pay annual dividends. Martin Marietta Energy Systems, which has operated Paducah since 1984 and Portsmouth since 1986 for DOE, will continue to operate both plants for USEC. Closing one of the two facilities will be studied, especially in light of a 40% world surplus of capacity over demand. USEC also will consider other nuclear-fuel-related ventures. USEC will produce only low-enriched uranium, not weapons-grade material. Indeed, USEC will implement a contract now being completed under which the US will purchase weapons-grade uranium from dismantled Russian nuclear weapons and convert it into low-enriched uranium for power reactor fuel

  5. Mobile Melt-Dilute Treatment for Russian Spent Nuclear Fuel

    2002-01-01

    Treatment of spent Russian fuel using a Melt-Dilute (MD) process is proposed to consolidate fuel assemblies into a form that is proliferation resistant and provides critically safety under storage and disposal configurations. Russian fuel elements contain a variety of fuel meat and cladding materials. The Melt-Dilute treatment process was initially developed for aluminum-based fuels so additional development is needed for several cladding and fuel meat combinations in the Russian fuel inventory (e.g. zirconium-clad, uranium-zirconium alloy fuel). A Mobile Melt-Dilute facility (MMD) is being proposed for treatment of spent fuels at reactor site storage locations in Russia; thereby, avoiding the costs of building separate treatment facilities at each site and avoiding shipment of enriched fuel assemblies over the road. The MMD facility concept is based on laboratory tests conducted at the Savannah River Technology Center (SRTC), and modular pilot-scale facilities constructed at the Savannah River Site for treatment of US spent fuel. SRTC laboratory tests have shown the feasibility of operating a Melt-Dilute treatment process with either a closed system or a filtered off-gas system. The proposed Mobile Melt-Dilute process is presented in this paper

    Full Text Available This paper presents a dynamic model that can predict the dynamics of migration flows between source countries and host regions, as well as the dynamics of wage levels there. The model is constructed within the framework of neoclassical economics and human capital theory in continuous time. Thanks to liberalization of migration policy in Russia in 2007, the model could be successfully employed to Russian regions and the Commonwealth of Independent States (CIS, which have visa-free entry regulations with the Russian Federation. Employing the model on statistical data, we forecast the number and origin composition of foreign labor force from the CIS into Russian regions for 2010-2016. The purpose of our further research is to classify migrants by skills

    Without fanfare, 600 Russian scientists here at CERN, the European particle physics laboratory, are playing key roles in building the Large Hadron Collider (LHC), a machine that will explore fundamental questions such as why particles have mass, as well as search for exotic new particles whose existence would confirm supersymmetry, a popular theory that aims to unify the four forces of nature. In fact, even though Russia is not one of CERN's 20 member states, most top high-energy physicists in Russia are working on the LHC. Some say their work could prove the salvation of high-energy physics back home.

    1998-01-01

    In the US, impure Pu-containing materials such as residues and scrapes are in storage, in known quantities, and in materials of various compositions with known Pu contents. However, in Russia, there are no substantial quantities of accumulated impure Pu-containing materials awaiting processing either for disposition or for transuranic (TRU) geologic disposal as there are in the Us. during the Cold War, the Russian approach to Pu processing for weapons production was different from that of the US. All impure Pu- containing materials were routinely reprocessed, and the residual Pu was recovered and purified for reuse until residual Pu levels of less than 200 mg/kg (less than 200 ppm) in any discharged solid process waste streams were reached. Wastes containing less than 200 ppm Pu were routinely discharged for burial in cement waste forms. Russia is studying changing from this practice of recovery of impure Pu for reuse to immobilizing future impure Pu-containing materials into solids at higher concentrations of Pu than 200 ppm for eventual geologic disposal

    2016-12-01

    Full Text Available This article deals with the process of establishment and development the Russian revival style in Russian Empire’s architecture of the 19th - early 20th centuries. During this period Russian society experienced intense changes that included innovations in technology, engineering and the art of building. Taking its origin from “Russian-byzantine” style in orthodox church building, the Russian revival style developed as a mixture of tradition and innovation. This eclectic style was inspired by the romantic revival movement of Western Europe and based on the interest in the historic monuments of the nation, especially in examples of pre-Peterine Russian architecture of the 17th century. The historicism of Russian Revival style resonated with the popular nationalism and pan-Slavism of the period. New style became a manifestation of the Russian national idea depicting in stone the specialty and uniqueness of our history and culture. Today the increasing interest to national cultural heritage actualizes the investigations of this extraordinary period of creativity represented by works of such famous architects as V. Stasov, K. Thon, V. Sherwood, I. Ropet and others. The appealing to “Russian-byzantine” style in modern church construction shows the power and vitality of its creative impulse.

  10. Transition Metal Systematics of Opx-Enriched Harzburgites From the Cascades Arc With Implications for the Origin of Cratonic Peridotites

    Turner, S. J.

    2007-12-01

    A number of peridotite xenoliths collected from the Simcoe volcanic field region of the Cascades arc exhibit notable enrichment of modal orthopyroxene. The process driving this enrichment is most likely metasomatism of the mantle wedge by Si-rich fluids derived ultimately from the underlying slab. By investigating the resultant elemental systematics associated with subduction zone metasomatism of this type, we hope to shed light on the origin of other opx-rich peridotites, such as those seen in many cratonic xenolith suites. The xenoliths found in the Simcoe volcanic field provide a rare opportunity to examine the composition of sub arc mantle, as it is unusual to find mantle xenoliths in volcanic arc lavas. The samples were analyzed using laser ablation ICPMS and their bulk compositions were reconstructed from point-counted mineral modes. Two-pyroxene mineral thermometry of the samples yield temperatures of approximately 1000 degrees C, corresponding to a depth of origin at uppermost mantle pressures if typical arc geotherms are assumed. Most of the peridotites are harzburgites or olivine-orthopyroxenites (Mg#s 0.88-0.9; opx mode 0.15-0.9), with small amounts of clinopyroxene (rare earths, consistent with a metasomatic origin for these opx-rich harzburgites. Of note is the counterintuitive systematics of Zn. Whole-rock Zn decreases with opx, but Zn in olivine also decreases with opx mode while Zn in opx increases with opx mode, hence the decrease in whole- rock Zn is not simply due to mechanical segregation of harzburgite into opx- and ol-rich zones. In summary, the REE signatures suggest the subducting slab as the most likely candidate for the source of the fluids that caused the opx enrichment. The opx-enrichment itself and the unusual trends in Zn suggest a reaction between a silicic fluid and normal harzburgite. Moreover, the concomitant decrease in olivine and whole-rock Zn with opx mode suggests significant leaching of Zn from the peridotite during this

  13. Rhetoric versus reality: Russian threats to European energy supply

    International Nuclear Information System (INIS)

    Goldthau, Andreas

    2008-01-01

    European gas demand will rise from presently 540 billion cubic meters (bcm) to around 800 bcm in 2030. As more than 50 percent of overall European imports originate from Russia, fears have been expressed that the Kremlin could use energy resources as a foreign policy tool. A thorough assessment of domestic consumption, production and investment volumes however reveals that Russian supply will have difficulties in matching growing domestic and European demand. Hence, as the author argues, the threat to European gas supply does not lie in geopolitics, but rather in a lack of investment in the Russian upstream sector. Higher domestic Russian gas prices, enhanced energy efficiency and increases in non-Gazprom production would however make it possible for Russia to meet domestic demand and its export commitments for natural gas

  14. Adaptation of Russian Christian Names into the Mari Language

    2017-11-01

    Full Text Available This article analyses the phonetic and morphological adaptation of Christian personal names in the Mari language. The work examines personal names recorded in different regions among the Mari. The composition of the presented data is not exhaustive; it does, however, allow one to observe some general patterns of the adaptation process. The main part of the article is preceded by a brief overview of the Christianization of the Mari region and the contacts between the Mari and the Russian-speaking population; the features of the local dialects of the Russian language are briefly stated. The Mari language incorporated a significant number of Russian names. The source of loans included, besides the standard church name forms, also the numerous varieties found in the Russian dialects. As part of the study, phonetic, structural changes of Christian names in the Mari language are revealed and the reasons for the majority of these transformations are identified. The author also pays attention to the intermediary role of the neighbouring Turkic languages in the penetration of Russian names into the Mari language. Changes in borrowed names were induced by internal Mari linguistic rules, as well as dialectal features of the local Russian dialects. The identification of systematic phonetic and structural transformations helps to determine the origin of obscure anthroponyms.

    It could be fairly said that while the Cold War arose in an atmosphere of mutual mistrust and hostility, it is ending with an equal amount of confusion and uncertainty. More than a year has passed since the US and Russia signed a tentative HEU agreement in August 1992. Many of the details have been worked out, but major questions remain. And they're not just on the Russian side. The fine points of President Clinton's overall nuclear policy are only now beginning to emerge. In his first major foreign policy address, before the United Nations in late September, Clinton called for a worldwide ban on the production of plutonium and HEU for nuclear weapons. open-quotes Growing global stockpiles of plutonium and highly enriched uranium are raising the danger of nuclear terrorism for all nations,close quotes said Clinton before the UN. open-quotes We will press for an international agreement that would ban production of these materials for weapons forever.close quotes As the veil lifts from Clinton's nuclear policy, it appears the Administration realizes that Russia may have more HEU than originally thought. That possibility has been confirmed by Minatom Minister Mikhailov's disclosures to the NUKEM Market Report, which brought a greater degree of certainty to estimates that had been floating around for some time. When the Bush Administration signed the HEU pact, it apparently thought the 500 metric tons comprised most of the former Soviet Union's nuclear arsenal. Now that the number appears higher, Clinton may propose to accelerate and enlarge the HEU deal. He is due to summit with Yeltsin, if Yeltsin survives, next spring. The 500-metric-ton deal may only be the first step

    The Russian Research Reactor Fuel Return (RRRFR) Program, under the U.S. Department of Energy's Global Threat Reduction Initiative, began returning Russian-supplied high-enriched uranium (HEU) spent nuclear fuel (SNF), stored at Russian-designed research reactors throughout the world, to Russia in January 2006. During the first years of making HEU SNF shipments, it became clear that the modes of transportation needed to be expanded from highway and railroad to include sea and air to meet the extremely aggressive commitment of completing the first series of shipments by the end of 2010. The first shipment using sea transport was made in October 2008 and used a non-Russian flagged vessel. The Russian government reluctantly allowed a one-time use of the foreign-owned vessel into their highly secured seaport, with the understanding that any future shipments would be made using a vessel owned and operated by a Russian company. ASPOL-Baltic of St. Petersburg, Russia, owns and operates a small fleet of vessels and has a history of shipping nuclear materials. ASPOL-Baltic's vessels were licensed for shipping nuclear materials; however, they were not licensed to transport SNF materials. After a thorough review of ASPOL Baltic's capabilities and detailed negotiations, it was agreed that a contract would be let with ASPOL-Baltic to license and refit their MCL Trader vessel for hauling SNF in support of the RRRFR Program. This effort was funded through a contract between the RRRFR Program, Idaho National Laboratory, and Radioactive Waste Management Plant of Swierk, Poland. This paper discusses planning, Russian and international maritime regulations and requirements, Russian authorities reviews and approvals, licensing, design, and modifications made to the vessel in preparation for SNF shipments. A brief summary of actual shipments using this vessel, experiences, and lessons learned also are described.

    Full Text Available Fermented dairy products have a high nutritional and biological value and functional properties beneficial to human health; they are very diverse and have a long history. Fermentation of milk is a complex technological, physical and biochemical process that occurs under the influence of two enzymes of lactic acid bacteria — -galactosidase and lactate dehydrogenase. Requirements for biological properties of starter microorganisms and fermentation technology are strictly regulated. Based on the starter cultures used, we can single out fermented dairy products of lactic acid and mixed (lactic acid and alcohol fermentation. There are adapted, partially adapted and non-adapted cultured milk products for children, some of which are enriched with pro- and prebiotics to enhance functional properties. The article provides information about one of the first Russian non-adapted fermented milk products for infants enriched with inulin, fruit and cereals.

    In this paper, we apply the multifractal detrended fluctuation analysis (MFDFA) to the Russian stock price returns. To the best of our knowledge, this paper is the first to reveal the multifractal structures for the Russian stock market by financial crises. The contributions of the paper are twofold. (i) Finding the multifractal structures for the Russian stock market. The generalized Hurst exponents estimated become highly-nonlinear to the order of the fluctuation functions. (ii) Computing the multifractality degree according to Zunino et al. (2008). We find that the multifractality degree of the Russian stock market can be categorized within emerging markets, however, the Russian 1998 crisis and the global financial crisis dampen the degree when we consider the order of the polynomial trends in the MFDFA.

  20. Use of highly enriched uranium at the FRM-II

    The new FRM-II research reactor in Munich, Germany, provides a high flux of thermal neutrons outside of the core at only 20 MW power. This is achieved by using a single compact, cylindrical fuel element with highly enriched uranium (HEU) which is cooled by light water and placed in the center of a large heavy water tank. The paper outlines the arguments which have led to this core concept and summarizes its performance. It also reports on alternative studies which have been performed for the case of low enriched uranium (LEU) and compares the data of the two concepts, with the conclusion that the FRM-II cannot be converted to LEU. A concept using medium enriched uranium (MEU) is described as well as plans to develop such a fuel element in the future. Finally, it is argued that the use of HEU fuel elements at the FRM-II does not - realistically -involve any risk of proliferation. (author)

    2008-02-15

    In 2004, President Poutine decided to replace the atomic energy ministry (Minatom) by the federal atomic energy agency (Rosatom). Several projects were launched during the next two years which aimed at bringing back Russia to the fore front of the world leaders of nuclear energy use and nuclear technology export. In 2007, Rosatom agency was changed to a public holding company and a new company, named Atomenergoprom, was created which gathers all civil nuclear companies (AtomEnergoMash for the exploitation of power plants, Technabsexport (Tenex) specialized in enrichment or Atomstryexport in charge of export activities). Thus, Rosatom is at the head of all civilian and military nuclear companies, of all research centers, and of all nuclear and radiological safety facilities. In 2006, Russian nuclear power plants supplied 15.8% of the whole power consumption. Russia wishes to develop its nuclear program with the construction of new reactors in order to reach a nuclear electricity share of 25% from now to 2020. This paper presents first the 2007 institutional reform of the Russian atomic sector, and the three sectorial federal programmes: 1 - development of the nuclear energy industrial complex for the 2007-2010 era and up to 2015 (future power plants, nuclear fuel centers and reactor prototypes), 2 - nuclear safety and radioprotection for the 2008-2015 era (waste management, remedial actions, radiation protection), 3 - military program (confidential). Then, the paper presents: the international actions (export of Russian technology, cooperation agreements, non-proliferation), the situation of the existing nuclear park (reactors in operation, stopped, under construction and in project), the fuel cycle activities (production of natural uranium, enrichment, fuel fabrication, spent fuel storage, reprocessing, waste management), the nuclear R and D in Russia, and the nuclear safety authority.

    Thermophilic microbial communities that are active in a high-solids environment offer great potential for the discovery of industrially relevant enzymes that efficiently deconstruct bioenergy feedstocks. In this study, finished green waste compost was used as an inoculum source to enrich microbial communities and associated enzymes that hydrolyze cellulose and hemicellulose during thermophilic high-solids fermentation of the bioenergy feedstocks switchgrass and corn stover. Methods involving the disruption of enzyme and plant cell wall polysaccharide interactions were developed to recover xylanase and endoglucanase activity from deconstructed solids. Xylanase and endoglucanase activity increased by more than a factor of 5, upon four successive enrichments on switchgrass. Overall, the changes for switchgrass were more pronounced than for corn stover; solids reduction between the first and second enrichments increased by a factor of four for switchgrass while solids reduction remained relatively constant for corn stover. Amplicon pyrosequencing analysis of small-subunit ribosomal RNA genes recovered from enriched samples indicated rapid changes in the microbial communities between the first and second enrichment with the simplified communities achieved by the third enrichment. The results demonstrate a successful approach for enrichment of unique microbial communities and enzymes active in a thermophilic high-solids environment.

Both Russia and the Baltic states are the states that make up the Baltic region. The role of this region in the European integration is the key. The border between Russia and the European Union, Russia and the EU are in direct contact, there is a direct interaction between the peoples of Europe, divided by confrontations of the twentieth century. In this border area sociocultural diffusion occurs between the two parts of the European continent. Factor of cooperation of neighbors is an essential guarantee of stability of the world system. For this cooperation to be productive, you must have an adequate view of the neighbors, about the processes that take place there. Knowing immediate environment in a globalized world is a prerequisite for good neighborly relations. The condition of willingness to help, if needed. In the current civilization elevated risk mutual definitely be in demand. Historical experience shows that the lack of objective knowledge is the cause of misunderstanding, and often the source of origin of enmity. This is not only of interest to neighboring nations, but the need to have certain knowledge about them, are closely linked to historical responsibility. Feature stories is that it is inextricably linked with modernity. For public decision-making needs of reliable knowledge about the processes that led to the present, the historical conditions of social psychology folding neighboring nations, forms of expression of their national characteristics.

    A discussion is presented of the present stage of development of large-scale enrichment of 15 N. The most important processes utilized to separate nitrogen isotopes, namely chemical exchange in the NO/NO 2 /HNO 3 system and low-temperature distillation of NO at -151 0 C, are compared, especially with respect to their economics and use of energy. As examples, chemical exchange plants in the GDR are discussed, and the research activities necessary to optimize the process, especially to solve aerodynamic, hydrodynamic, interface and processing problems, are reviewed. Good results were obtained by the choice of an optimum location and the design of a plant for pre-enrichment to 10 at.% 15 N and an automatically operating two-section cascade for the high enrichment of 15 N to more than 99 at.%. The chemical industry has taken over operation of the plant with the consequence that the raw materials are all available without additional transport. All by-products (nitrous gases and sulphuric acid) are returned for use elsewhere within the industry. The technology of the plant has been chosen so that the quantity of highly enriched product can be varied within a wide range. The final product is used to synthesize more than 250 different 15 N-labelled compounds which are also produced on an industrial scale. (author)

    2011-07-01

    The allelic diversity of high-moleculat-weght glutenin subunits (H WIGS) in Russian and Ukrainian bread wheat cultivars was analyzed. The diversity of spring wheat cultivars for alleles of the Glu-1 loci is characterized by medium values of the polymorphism index (polymorphism information content, PlC), and in winter wheats it varies from high at the Glu-A1 locus to low at the Glu-D1 locus. The spring and winter cultivars differ significantly in the frequencies of alleles of the glutenin loci. The combination of the Glu-A1b, Glu-B1c, and Glu-D1a alleles prevails among the spring cultivars, and the combination of the Glu-A1a, Glu-B1c, and Glu-D1d alleles prevails among the winter cultivars. The distribution of the Glu-1 alleles significantly depends on the moisture and heat supply in the region of origin of the cultivars. Drought resistance is associated with the Glu-D1a allele in the spring wheat and with the Glu-B1b allele in the winter wheat. The sources of the Glu-1 alleles were identified in the spring and wheat cultivars. The analysis of independence of the distribution of the spring and winter cultivars by the market classes and by the alleles of the HMWGS loci showed a highly significant association of the alleles of three Glu-1 loci with the market classes in foreign cultivars and independence or a weak association in the Russian and Ukrainian cultivars. This seems to be due to the absence of a statistically substantiated system of classification of the domestic cultivars on the basis of their quality.

    Microbial communities enriched from diverse environments have shown considerable promise for the targeted discovery of microorganisms and enzymes for bioconversion of lignocellulose to liquid fuels. While preservation of microbial communities is important for commercialization and research, few studies have examined storage conditions ideal for preservation. The goal of this study was to evaluate the impact of preservation method on composition of microbial communities enriched on switchgrass before and after storage. The enrichments were completed in a high-solid and aerobic environment at 55 °C. Community composition was examined for each enrichment to determine when a stable community was achieved. Preservation methods included cryopreservation with the cryoprotective agents DMSO and glycerol, and cryopreservation without cryoprotective agents. Revived communities were examined for their ability to decompose switchgrass under high-solid and thermophilic conditions. High-throughput 16S rRNA gene sequencing of DNA extracted from enrichment samples showed that the majority of the shift in composition of the switchgrass-degrading community occurred during the initial three 2-week enrichments. Shifts in community structure upon storage occurred in all cryopreserved samples. Storage in liquid nitrogen in the absence of cryoprotectant resulted in variable preservation of dominant microorganisms in enriched samples. Cryopreservation with either DMSO or glycerol provided consistent and equivalent preservation of dominant organisms. A stable switchgrass-degrading microbial community was achieved after three 2-week enrichments. Dominant microorganisms were preserved equally well with DMSO and glycerol. DMSO-preserved communities required more incubation time upon revival to achieve pre-storage activity levels during high-solid thermophilic cultivation on switchgrass. Despite shifts in the community with storage, the samples were active upon revival under thermophilic and

    Full Text Available These three separate notes are united by the fact that the words considered originated from Russian seminarian slang and borrowed from Greek, with the first two words illustrating unobvious, punning Graecism. The rare verb vz"efantúlit' ‘to subject smb. to cruel punishment’ (and its derivatives vz"efantúlka, vz"efantúlivan'e is related to the Biblical Semitism ἐφφαθά (Mark 7.34, which was read “by Erasmus spelling” (cf. Latin eppheta and passed through a series of word-building transformations. The verb smorozit' ‘to say smth. stupid or inappropriate’ has additional arguments in favor of its origin from contamination of Greek μωρός and Russian морóз in a Russian seminarian or gymnasial environment. The author has also extensively traced the way this verb is defined in dictionaries and researched by other scholars. Finally, an essay on the word áksiós ‘church acclamation «He is worthy!»’ (from Greek ἄξιος and its comic figurative pl. aksiósy ‘hair’ considers the whole history of the usage of these lexical units in all registers of the Russian language, including dialects.

  18. Origin of enormous trace metal enrichments in weathering mantles of Jurassic carbonates: evidence from Sr, Nd and Pb isotopes

    Weathering mantels are widespread worldwide and include lateritic, sandy and kaolinite-rich saprolites and residuals of partially dissolved carbonate rocks. These old regolith systems have a complex history of formation and may present a polycyclic evolution due to successive geological and pedogenetic processes that affected the profile. Until now, only few studies highlighted the unusual content of associated trace elements in this type of weathering mantle. For instance, these enrichments can represent about five times the content of the underlying Bajocian to Oxfordian limestone/marl complexes, which have been relatively poorly studied compared to weathering mantle developed on magmatic bedrocks. Up to now, neither soil, nor saprolite formation has to our knowledge been geochemically elucidated. Therefore, the aim of this study was to examine more closely the soil forming dynamics and the relationship of the chemical soil composition to potential sources (saprolite, Bajocian silty marls and limestones, atmospheric particles deposition...). Of special interest has also been the origin of trace metals and the processes causing their enrichments. Especially Rare Earth Element (REE) distribution patterns and Sr, Nd and Pb isotope ratios are particularly well suited to identify trace element migration, to recognize origin and mixing processes and, in addition, to decipher possible anthropogenic and/or "natural" atmosphere-derived contributions to the soil. Moreover, leaching experiments shall help to identify mobile phases in the soil system. This may inform on the stability of trace elements and especially on their behaviour in these Fe-enriched carbonate systems. Trace metal migration and enrichments were studied on a cambisol developing on an underlying Jurassic limestone. The base is strongly enriched among others in rare earth elements (ΣREE: 2640ppm) or redox-sensitive elements such as Fe (44 wt.%), V (920ppm), Cr (700ppm), Zn (550ppm), As (260ppm), Co (45ppm

    In order to enhance the sensitivity of nuclear material identification system (NMIS) against the change of nuclear material enrichment, the principle of high order statistic feature is introduced and applied to traditional NMIS. We present a new enrichment identification method based on cross-correlation and high order spectrum algorithm. By applying the identification method to NMIS, the 3D graphs with nuclear material character are presented and can be used as new signatures to identify the enrichment of nuclear materials. The simulation result shows that the identification method could suppress the background noises, electronic system noises, and improve the sensitivity against enrichment change to exponential order with no system structure modification.

    While the IAEA has been a vigorous supporter of the RERTR programme since its inception. RERTR and the related fresh and spent fuel return efforts have gained new momentum with the launching of the Global Threat Reduction Initiative (GTRI) by U.S. Energy Secretary Abraham here in Vienna on May 25, 2004. All of the activities to be be discussed are included within the framework of the GTRI. The international programmes to qualify high density, LEU, dispersion fuels based on U-Mo alloys have run into unexpected technical difficulties that will delay qualification. A number of the presentations address the problems that have been encountered. At the same time, it is encouraging that the international resolve to reduce and eventually eliminate HEU in international commerce appears to have strengthened. In the past year, fresh HEU at research reactors in different countries have been returned to the country of origin. In all these examples, the return of the fresh fuel was accompanied by plans for conversion of existing reactors or design of new reactors to use LEU, as well as for the repatriation of spent research reactor fuel. The IAEA, particularly the Department of Technical Cooperation and my Department of Nuclear Energy has played an important role in implementing these fresh fuel return activities. In addition, several of the reactor conversion projects will be carried out under the auspices of IAEA technical cooperation projects and with important involvement of the Department of Nuclear Energy. The IAEA has also supported the repatriation of spent fuel to the country of original enrichment. The U.S. spent fuel acceptance programme has been operating for more than eight years, and was originally scheduled to terminate in 2006. Important announcements concerning the extension of the U.S. programme are expected. At the same time, the IAEA has been working hard with the U.S. and Russia to initiate the Russian research reactor spent fuel return programme. We are

    Full Text Available The aim of the present study was to operationalize a Russian version of the Highly Sensitive Person Scale (HSPS. The empirical data were collected in two ways: active, through oral advertising and inviting those who wish to take part in the study (snowball technique and passive (placement of ads about taking part in a research in social networks VKontakte and Facebook. As a result, 350 university students (117 men, 233 women, an average age of 18,2 (± 1,7 applied to a research laboratory and filled out the HSPS questionnaire, and another 510 respondents (380 women, 130 men, average age 22,6 ( ± 7,9 filled the HSPS online. The results of the study did not confirm the one-dimensional model of the construct, proposed by Aron & Aron (1997, as well as the most commonly used in the English-language studies three-factor solution. The hierarchical claster and confirmatory analyses used in the operationalization procedure allowed us to conclude that the variance of the Russian version of HSPS is best described in the framework of a two-factor model including the two separate subscales: Ease of Excitation (EOE, Low threshold of sensitivity (LTS. Sensory Processing Sensitivity may be defined as an increased susceptibility to external and internal stimuli, realized through negative emotional responses and deep susceptibility (distress to excessive stimulation.

  4. Comments on applications of reduced enrichment fuels

    International Nuclear Information System (INIS)

    Winkler, M.H.

    1983-01-01

    Full text: I will briefly describe the experience gained using different fuels in the SAPHIR reactor in Switzerland. The SAPHIR has been operating since 1957 and was the first swimming pool reactor built outside of the United States, which was originally known as the Geneva Conference Reactor. The first core was loaded with 20 percent enriched high density UO 2 fuel with a density of about 2.5 grams per cc, fabricated in 1955 by Oak Ridge National Laboratory. After a few years of operation at a power level of one MW, more than one batch of the elements released small amounts of fission products mainly Xe and Kr. When these releases were discovered, high enriched fuel was becoming available so that the fuel fabricators began to produce the lower density high enriched fuels. During this transition from fabrication of low to high enriched fuels no one could foresee that the stone age of nuclear fuel fabrication would come back again. Therefore, we did not investigate the reasons for the fission product release from the high density low enriched UO 2 fuel. The second fuel type used in the SAPHIR was the 90 percent enriched low density U 3 O 8 fuel fabricated by NUKEM. This high enriched fuel has performed satisfactorily over the years. Since 1968, the core has been using improved 23 plate fuel elements with a loading of 280 grams of uranium. The reactor power has been recently increased to five MW. An additional increase in the power level to 10 MW is planned at the end of next year so that heavier loaded elements will be needed. In order to follow the recommendations of the INFCE working group 8C and in cooperation with the reduced enrichment program, we intend to initially reduce the fuel enrichment to 45 percent. Last year we ordered five fuel elements with a loading of 320 grams 235 U/element and 45 percent enrichment for full power tests. Unfortunately, the delivery of the necessary enriched fuel uranium has been delayed and it is not available at this time. If

    The Russian River carves a 110 mile path through Mendocino and Sonoma counties in western California, providing water for thousands of residents and acres of agriculture as well as a home for several species of endangered fish. The Russian River basin receives almost all of its precipitation during the October through March wet season, and the systems bringing this precipitation are often impacted by atmospheric river events as well as the complex topography of the region. This study will examine the performance of several high resolution (hourly, products and forecasts over the 2015-2016 and 2016-2017 wet seasons. Comparisons of event total rainfall as well as hourly rainfall will be performed using 1) rain gauges operated by the National Oceanic and Atmospheric Administration (NOAA) Physical Sciences Division (PSD), 2) products from the Multi-Radar/Multi-Sensor (MRMS) QPE dataset, and 3) quantitative precipitation forecasts from the High Resolution Rapid Refresh (HRRR) model at 1, 3, 6, and 12 hour lead times. Further attention will be given to cases or locations representing large disparities between the estimates.

    The Enrichment Meter Principle (EMP) is the basis for a commonly used standard test method for the non-destructive assay of 235U enrichment in bulk compounds [1]. The technique involves determining the net count rate in the direct 186 keV peak using medium or high energy gamma-ray spectrometry in a fixed geometry. With suitable correction for wall attenuation, compound type, rate loss (live time), and peaked background (if significant), the atom fraction of 235U may be obtained from the counting rate from a linear relationship through the origin. The widespread use of this method for field verification of enrichment [2,3] together with the fact that the response function rests on fundamental physics considerations (i.e., is not represented by a convenient but arbitrary form) makes it an interesting example of uncertainty quantification, one in which one can expect a valid measurement model can be applied. When applied using NaI(Tl) and region of interest analysis, the technique is susceptible to both interference error and bias [2-4]. When implemented using high-resolution gamma-ray spectroscopy, the spectrum interpretation is considerable simplified and more robust [5]. However, a practical challenge to studying the uncertainty budget of the EMP method (for example, to test linearity, extract wall corrections and so forth using modern methods) is the availability of quality experimental data that can be referenced and shared. To fill this gap, the research team undertook an experimental campaign [6]. A measurement campaign was conducted to produce high-resolution gamma spectroscopy enrichment meter data comparable to UF6 cylinder measurements. The purpose of this report is to provide both an introduction to and quality assurance (QA) of the raw data produced. This report is intended for the analyst or researcher who uses the raw data. Unfortunately, the raw data (i.e., the spectra files) are too voluminous to include in this report

    This report contains the results of reactor accident analyses for the University of Missouri Research Reactor (MURR). The calculations were performed as part of the conversion from the use of highly-enriched uranium (HEU) fuel to the use of low-enriched uranium (LEU) fuel. The analyses were performed by staff members in the Research and Test Reactor Department at the Argonne National Laboratory (ANL) and the MURR Facility. MURR LEU conversion is part of an overall effort to develop and qualify high-density fuel within the U.S. High Performance Research Reactor Conversion (USHPRR) program conducted by the U.S. Department of Energy National Nuclear Security Administration’s Office of Material Management and Minimization (M3).

    1997-01-01

    The Russian Federation holds the world's largest proven natural gas reserves, and produces more natural gas than any other nation. Russian exports of gas to Europe and the other nations of the Commonwealth of Independent States (CIS) have a significant impact on natural gas markets throughout Europe and Asia. The aim of this three part study is to inform the international energy and investment community about the current status of the Russian gas industry and the prospects for its future development through 2010. It is also intended to provide an opportunity for the appropriate authorities in the Russian Federation to assess the needs of the industry and to consider areas for possible collaboration with the international investment community and international organizations in a rapidly changing economic and business environment. The study was prepared by the Energy Branch of the United Nations Department for Development Support and Management Services (UN/DDSMS). It was financed by the United Nations Development Programme (UNDP). Part I describes Russian gas reserves and potential resources, and overviews the country's gas producing, pipeline and distribution industries. Additionally, it summarizes the markets for Russian natural gas including domestic and external markets. It discusses the primary economics and potential factors that currently impact the Russian gas industry during the Federation's transition toward a market economy. Part II highlights possible directions for the development of the Russian gas resource base, including upstream gas production and downstream marketing in five-, ten- and fifteen-year time frames. It projects export opportunities for Russian Federation gas and evaluates the options for shaping regional and international markets. Part III addresses the legal and regulatory framework and fiscal regime of the Russian gas industry. It also reviews the major investment requirements and the equipment and training needs of the Russian gas

  9. Anthroponyms of Non-Biblical Origin in Stefan Yavorsky’s Sermons

    2014-06-01

    Full Text Available The article focuses on archbishop Stefan Yavorsky’s works which reflect the transitional character of late 17th — early 18th centuries Russian sermons. Before that time the genre had been loyal to the canonical principles of scholasticism, and beginning with Stefan Yavorsky the sermon was enriched with new ways of material presentation and new content. The use of numerous biblical personal names, names of saints, Fathers of the Church and theologians represents a trait inherent in the sermon as a genre, a wide use of non-biblical names being chiefly a distinctive feature of scholastic works. Among those names the author points out: 1 names of saints, Fathers of the Church, church hierarchs; 2 names of gods and heroes of Antiquity; 3 names of ancient philosophers, historians and rulers; 4 names of foreign rulers, historians and public figures of the modern period; 5 names of Russian rulers. Thereby, the anthroponyms of non-biblical origin could be attributes of both “informational” (names of ancient gods and historical figures and “spiritual” (names of saints, Fathers of the Church, church hierarchs parts of a sermon. The author distinguishes the following functions of the analyzed names: 1 indication of sources of information (most frequent; 2 naming of the characters of a story or parable cited for illustrative purposes; 3 naming of a described person.

    Full Text Available This article aims to give an overview of literary instruction in schools of the russification era at the beginning of the 20th century in Estonia; this was likewise the curriculum of literary study offered to the generation of educated youth which included the Young Estonians. Based on official documents, archival materials, and memoirs, and through analyses of anthologies, literary histories, and teaching methods in use at the time, we attempt to reconstruct the outlines of literary reading and requirements for students in various types of schools. When, as a result of school reform, Russian became the language of instruction; lessons in Russian became central in the curriculum, alongside the word of God; selections from Russian literature were read in the original language. In the lower grades, teaching was by the so-called ”natural method”, intended to guarantee swift achievement of fluency in ”living Russian language”; this was later replaced by systematic textual analysis, which distinguished between belles lettres and other types of texts. However, the study of literature was always subordinated to the goals of language instruction. In institutions of secondary education, study of Russian literature was separate from language instruction. Indeed, Russian literature was the only literature systematically studied in high schools (though one must keep in mind that not all schools completely followed the official program. Private schools were especially noticeable for their greater freedom, though all of them had to take general curriculum directives into account. Reading of literary texts connected with other languages thus had to remain almost purely illustrative. In view of the above, in the upper grades of elementary school and high school, students obtained a thorough introduction to the Russian classics. According to the official school curriculum, Russian literary history ended with Nikolai Gogol. Attempts were made to ignore

    2003-01-01

    This article proposes a brief discussion of various assessments of Russian oil reserves, of the evolutions of Russian oil production (Russia is the second world producer after Saudi Arabia), of the distribution of Russian oil exports among various regions, and of the decrease of Russian oil consumption between 1992 and 2002. It describes the evolution of the actor system as the oil sector has been largely privatised since 1992, and indicates the main companies which should control the Russia market on a medium term. It also discusses the obstacles for the development of Production Sharing Agreements (PSA) between these companies. It addresses the issue of modernisation of the oil transport system as its status and its condition are often an obstacle to oil export for Russian companies. The article finally discusses the price issue, the relationship between Russia and other OPEC countries, and the need for huge investments

    High-mineralised waters are showing frequently high concentrations of 226 Ra and 228 Ra, which are positively correlated with salinity. The investigated pit water is a high mineralised, reducing NaCl-brine (up to 230 g/l), which contains in coexcidence with Ba (up to 2500 ppm) and Sr, high 226 Ra concentrations (up to 63 Bq/l) and 228 Ra concentrations (up to 28 Bq/l). Feeding river systems with this water, the contact of the pit water with sulphate bearing surface water results in a precipitation of Ba and Ra as radiobaryte, with 226 Ra concentrations up to several tens of kBq/kg. The pit waters originate from a mixture of formation and meteoric waters, older than 20 Ma. High concentrations of mainly Na + and C1 - , but K + , Ca 2+ and HCO 3 - as well, are explained by dissolution of Permian salt deposits. Ba 2+ is enriched by sulphate-reducing bacteria, which destroy detrital baryte. Radium enters the water by leaching and alpha-recoil effect, but a large fraction of it is adsorbed at the surfaces of mineral grains. Mainly Ba 2+ and Sr 2+ , but univalent ions like Na + and K + as well, are desorbing Ra 2+ from the surface of minerals and take their place. Elution experiments show that beside the ion exchange of the cations, the type and amount of anions control the radium mobilisation. It seems that large anions like NO 3 - are disturbing the hydrate coat around minerals and therefore, enhance the ion exchange process. (author)

    Boris A. Natal’in

    2011-01-01

    Full Text Available The publication is devoted to the history of one of the greatest concepts of tectonics of Asia, that has been widely accepted and yet obliterated with time, while the splendors of this concept are doubtful. Numerous citations in the Russian papers to «The Face of the Earth» by Edward Suess and the fact that he was elected a Corresponding Member of the Imperial Saint Petersburg Academy of Sciences clearly demonstrate how highly Suess’s contribution to studies of the structure and geological evolution of Asia was valued by the Russian geological community. Suess’s letters to Vladimir A. Obruchev give evidence how close and productive the relationship between Edward Suess and the Russian researchers was in the late 19th and the early 20th centuries and also illustrate how the great tectonic concept of Asia [Suess, 1908] was born and developed. The idea of centrifugal propagation of tectonic waves of the Altaids from a continental node located somewhere in Siberia was mainly inspired by Suess’s profound scientific intuition. The idea matured after Edward Suess got acquainted with Ivan D. Chersky’s paper [Черский, 1886] that greatly facilitated in shaping and improving this idea. It was mailed to Suess by Vladimir A. Obruchev who translated the paper, attached his own map and provided explanations to Chersky’s ideas. The available historical documents suggest that Vladimir A. Obruchev facilitated communication between the Russian geologists, on the one side, and Edward Suess and other Austrian geologists who conducted geological studies in Asia, on the other side. Being actively involved in exchange of publications and cooperation in field data processing, Edward Suess was aware of all the details of the Russian geological studies.In addition to the concept of tectonic arcs of the Altaids and descriptions of main geological structures located in Northern Asia and China, Edward Suess adopted a concept of disjunctive dislocations

These structural features are characterized by originality and unconventional use. Language material is the result of authors` direct observation of spontaneous verbal communication between people of different social and age groups. The words and remarks were analyzed in compliance with the communication system of national Russian language and cultural background of popular speech. Studies have discovered that in spoken discourse there are some other ways to increase the expression statement. It is important to note that spontaneous speech identifies lacunae in the nominative language and its vocabulary system. It is proved, prefixation is also effective and regular way of the same action presenting. The most typical forms, ways and means to update language resources as a result of the linguistic creativity of native speakers were identified.

    Full Text Available The article enriches the discussion on the legal reasons and conditions fostering the viability of democratic constitutions by analyzing the rich experience of the Russian Constitution of 1993. Particular attention is paid to the concept of countermajoritarian institutions. The authors elaborate the idea that countermajoritarian institutions can play an important role in ensuring the viability (put in other terms, the proper balance between stability, adaptability, and dynamic development of modern democratic constitutions as well as political regimes.The article presents evidence-based data showing that the President and the Constitutional Court of the Russian Federation systematically acted as countermajoritarian institutions at the initial stage of the implementation of the “blueprint for the future” set down in the 1993 Russian Constitution. As a result of the activities of these institutions, strong legal frameworks were created that are necessary for the establishment of anew constitutional system of the Russian state and law.Today, the Russian Constitution of 1993 is one of the longest lasting democratic constitutions in the world (the average “life expectancy” of democratic constitutions adopted over the past 250 years is about seventeen years. The study of the countermajoritarian provisions in the 1993 Russian Constitution is of both theoretical and practical importance. In particular, the results of the study can be useful in creating efficient legal instruments for the maintenance of political stability and social development management both within sovereign states and within interstate communities.

    Full Text Available The paper reviews previous and recently obtained geological, stratigraphic and geochronological data on the Russian-Kazakh Altai orogen, which is located in the western Central Asian Orogenic Belt (CAOB, between the Kazakhstan and Siberian continental blocks. The Russian-Kazakh Altai is a typical Pacific-type orogen, which represents a collage of oceanic, accretionary, fore-arc, island-arc and continental margin terranes of different ages separated by strike-slip faults and thrusts. Evidence for this comes from key indicative rock associations, such as boninite- and turbidite (graywacke-bearing volcanogenic-sedimentary units, accreted pelagic chert, oceanic islands and plateaus, MORB-OIB-protolith blueschists. The three major tectonic domains of the Russian-Kazakh Altai are: (1 Altai-Mongolian terrane (AMT; (2 subduction-accretionary (Rudny Altai, Gorny Altai and collisional (Kalba-Narym terranes; (3 Kurai, Charysh-Terekta, North-East, Irtysh and Char suture-shear zones (SSZ. The evolution of this orogen proceeded in five major stages: (i late Neoproterozoic–early Paleozoic subduction-accretion in the Paleo-Asian Ocean; (ii Ordovician–Silurian passive margin; (iii Devonian–Carboniferous active margin and collision of AMT with the Siberian continent; (iv late Paleozoic closure of the PAO and coeval collisional magmatism; (v Mesozoic post-collisional deformation and anarogenic magmatism, which created the modern structural collage of the Russian-Kazakh Altai orogen. The major still unsolved problem of Altai geology is origin of the Altai-Mongolian terrane (continental versus active margin, age of Altai basement, proportion of juvenile and recycled crust and origin of the middle Paleozoic units of the Gorny Altai and Rudny Altai terranes.

    2016-06-01

    The cultural human heritage is important for the identity of following generations and has to be preserved in a suitable manner. In the course of time a lot of information about former cultural constructions has been lost because some objects were strongly damaged by natural erosion or on account of human work or were even destroyed. It is important to capture still available building parts of former buildings, mostly ruins. This data could be the basis for a virtual reconstruction. Laserscanning offers in principle the possibility to take up extensively surfaces of buildings in its actual status. In this paper we assume a priori given 3d-laserscanner data, 3d point cloud for the partly destroyed church. There are many well known algorithms, that describe different methods of extraction and detection of geometric primitives, which are recognized separately in 3d points clouds. In our work we put them in a common probabilistic framework, which guides the complete reconstruction process of complex buildings, in our case russian-orthodox churches. Churches are modeled with their functional volumetric components, enriched with a priori known probabilities, which are deduced from a database of russian-orthodox churches. Each set of components represents a complete church. The power of the new method is shown for a simulated dataset of 100 russian-orthodox churches.

    2011-05-01

    Full Text Available Since the end of the Cold War, the EU and Russia have managed to create an original framework for institutionalised cooperation despite asymmetric characteristics. Yet, the way these two main security actors interact has an impact on the (non-resolution of security issues in Europe, ranging from ‘‘frozen conflicts’’ to the discussion of the security architecture. Since the second mandate of President Putin, the relation has been characterised by two paradoxical features. On the one hand, the methodology and the domains of cooperation have reached a high degree of achievement. On the other hand, the political quality of the relationship has deteriorated and it is not able to achieve the desired ‘‘strategic partnership’’ that should be based on a common set of values and principles. This article aims to define multilateralism as a paradigm applicable to EU-Russian relations. It examines their relationship in the security and defence realm and the Union’s reactions to a new security approach by Russia since the 2008 Medvedev proposal. The article questions how the EU-Russian political dialogue impacts on multilateralism in the security field. The conclusion considers EU-Russian relations as a peculiar multilateral playground addressing common security challenges, which still needs to be developed further in order to be instrumental in the search for collective and legitimate solutions.

    1992-01-01

    Last year, as the Soviet Union began to crumble and the Bush-Gorbachev talks had advanced to consider the dismantling of actual warheads instead of mere delivery systems, Dr. Thomas L. Neff, a senior member of MIT's Center for International Studies, tinkered with the notion that one day soon the US could be buying Russian uranium from scrapped nuclear arms. He also considered the costly business of dismantlement and set to work on an ingenious proposal. The basic idea was simply to purchase the HEU from Russia using funds derived from savings in the US Department of Energy's enrichment enterprise. The proposal, now part of an umbrella agreement between the US and Russia announced in early September, promises large strategic benefits for the US in terms of both financing dismantlement (to the tune of $100 million annually), as well as political oversight for the operation itself. In the words of Dr. Neff, who made briefings to both governments on the proposal, open-quotes It's a budget-neutral, win-win solution.close quotes What follows is an illustrated, step-by-step analysis of the proposal, as well as a reprint of Dr. Neff's paper, Disposition of HEU and Pu from Nuclear Weapons, as presented to the Uranium Institute's annual symposium last month

    Full Text Available The article analyses practices of “Traditions and values of Russian business culture” course teaching at Lomonosov Moscow State University’s Faculty of Sociology. The experience allows drawing methodological and theoretical conclusions on the values of business culture which underlie models of the modern business behavior. The first part of the publication concerns analysis of tradition of studying Russian culture values, in the paradigm of which the Russian business culture exists. According to the findings, traditions are enrooted in the Orthodoxy and are determined by patrimonial memories and contradictions of the Russian people’s character, ideals and spiritual framework. A system of Russian business values is developed based on the traditions as well as literary heritage, biographies of famous Russian and Soviet economists and set of rules of ethics code of the pre-revolutionary Russian business class. The main elements of the system include the following values: faith, family, commitment to business, patriotism, natural ingenuity, ability to set and solve atask of extra complexity, original forms of labor organization, and prevalence of moral motivation forms over material ones. The second part of the article deals with succession of the above-mentioned values in the modern Russian business environment. The content analysis is applied to examine the continuity.

    At present, most 99Mo is produced in research, test, or isotope production reactors by irradiation of highly enriched uranium targets. To achieve the denser form of uranium needed for switching from high to low enriched uranium (LEU), targets in the form of a metal foil (~125-150 µm thick) are being developed. The LEU High Density Target Project successfully demonstrated several iterations of an LEU-fission-based Mo-99 technology that has the potential to provide the world’s supply of Mo-99, should major producers choose to utilize the technology. Over 50 annular high density targets have been successfully tested, and the assembly and disassembly of targets have been improved and optimized. Two target front-end processes (acidic and electrochemical) have been scaled up and demonstrated to allow for the high-density target technology to mate up to the existing producer technology for target processing. In the event that a new target processing line is started, the chemical processing of the targets is greatly simplified. Extensive modeling and safety analysis has been conducted, and the target has been qualified to be inserted into the High Flux Isotope Reactor, which is considered above and beyond the requirements for the typical use of this target due to high fluence and irradiation duration.

    Since its establishment in 2001, NTI (Nuclear Threat Initiative) has made important contributions towards securing weapon-usable nuclear material and reducing the threat of nuclear terrorism. Shortly after the terrorist attacks of September 2001, NTI pledged $1.15 million to the Agency?s Nuclear Security Fund, which has been used to achieve tangible nuclear security improvements: upgrades to physical protection of nuclear facilities and nuclear and radioactive material; urgently needed training in nuclear security for national officials; enhanced detection capabilities at border crossings; and improved national and international readiness for responding to terrorist acts. NTI has consistently sought to target its contributions to address areas of high priority. A primary point of focus has been to secure (and, where possible, eliminate) material that could be diverted for weapons purposes. In P roject Vinca , NTI committed $5 million in 2002 to help remove high enriched uranium fuel from a research reactor near Belgrade, for return to Russia. With support from Russia, the United States and NTI, seven transfers of fresh fuel back to Russia have been made since 2002 - a total of 112 kilograms of HEU. Current plans foresee further shipments of fresh HEU from another three countries in the next 15 months. The IAEA is also continuing to work on arrangements for the repatriation of spent research reactor fuel of Russian origin. In 2001, Sam Nunn and NTI president Charles Curtis approached the Kazakh Government to offer support for the safe transportation of the unused nuclear fuel from the shutdown BN-350 reactor - nearly 3000 kilograms - to the Ulba Metallurgical Plant JSC (UMP), where it could be dismantled and down-blended into LEU (NTI-Kazakhstan project). By the end of this year, 2897 kilograms of HEU - enough to produce dozens of nuclear bombs - will have been down-blended to LEU and placed in safe storage. Throughout the project, the IAEA has been implementing

    A small contract signed in FY92 with the Khlopin Radium Institute marked the beginning of the Russian Separations program. Under this contract the Khlopin Radium Institute performed laboratory and dynamic hot-cell testing using cobalt dicarbollide technology on simulated radioactive wastes similar to those found at DOE sites in the United States. The current scope of investigation has been extended to identify prospective technologies for application to other United States needs. The Khlopin Radium Institute project served as a model for three other pilot scale technology development projects. The premise of the pilot scale projects is to enable Russian scientists to demonstrate their technology in the context of DOE needs, using Russian technical expertise has proven to be a cost-effective means of screening Russian technologies

    Synthetic gases are usually generated from either cellulosic agricultural waste combustion or industrial release and could be subsequently transformed into acetate, ethanol, and/or butyrate by homoacetogenic bacteria, which commonly possess reductive acetyl-CoA synthesis pathway. Homoacetogen-based syngas fermentation technology provides an alternative solution to link greenhouse gas emission control and cellulosic solid waste treatment with biofuels production. The objective of our current project is to hunt for homoacetogens with capabilities of highly efficiently converting syngases to chemical solvents. In this study, we evaluated homoacetogens population dynamics during enrichments and pinpointed dominant homoacetogens representing diverse ecosystems enriched by different substrates. We enriched homoacetogens from four different samples including waste activate sludge, freshwater sediment, anaerobic methanogenic sludge, and cow manure using H2/CO2 (4:1) or formate as substrate for homoacetogen enrichment. Along with the formyltetrahydrofolate synthetase (FTHFS) gene (fhs gene)-specific real time qPCR assay and Terminal Restriction Fragment Length Polymorphism (T-RFLP) analysis, 16S rRNA based 454 high-throughput pyrosequencing was applied to reveal the population dynamic and community structure during enrichment from different origins. Enrichment of homoacetogenic populations coincided with accumulations of short chain fatty acids such as acetate and butyrate. 454 high-throughput pyrosequencing revealed Firmicutes and Spirochaetes populations became dominant while the overall microbial diversity decreased after enrichment. The most abundant sequences among the four origins belonged to the following phyla: Firmicutes, Spirochaetes, Proteobacteria, and Bacteroidetes, accounting for 62.1%-99.1% of the total reads. The major putative homoacetogenic species enriched on H2/CO2 or formate belonged to Clostridium spp., Acetobacterium spp., Acetoanaerobium spp

    1995-01-01

    An atom probe field ion microscopy characterization of three Russian pressure vessel steels has been performed. Field ion micrographs of several lath boundaries have indicated that they are decorated with a semicontinuous film of discrete brightly-imaging precipitates that were identified as molybdenum carbonitrides. In addition, extremely high phosphorus levels were measured at the lath boundaries. The phosphorus was found to be confined to an extremely narrow region indicative of monolayer type segregation. The phosphorus coverage determined from the atom probe results of the unirradiated materials agree with predictions based on McLean's equilibrium model of grain boundary segregation. The boundary phosphorus coverage of a neutron-irradiated weld material was significantly higher than in the unirradiated material. Ultrafine darkly-imaging copper- and phosphorus-enriched precipitates were also observed in the matrix of the neutron-irradiated material. (orig.)

    2010-05-01

    The historic database of tsunamis in the Black Sea contains 20 - 30 events with different level of validity, and at least six events occurred in 20th century. Numerical modeling of the last historic events is performed in the framework of shallow-water theory with use of code NAMI-DANCE. The computed tide-gauge records in Russian coastal locations are in good agreement with instrumental data for the 1939 and 1966 tsunamis. The tsunami of the landslide origin occurred in Sochi in 1970 is modeled in the framework of the two-layer model realized in TUNAMI. Also, some hypothetic tsunamis generated in the open part of the Black Sea are computed and the distribution of the tsunami height along the Russian and Turkish coast ais found. In particular, the tsunami amplification near Sochi is highest to compare with other coastal locations on the Russian coast of Black Sea.

    Full Text Available Using original documents from the Russian State Military Historical Archive, many of which are introduced for the first time, the author reveals details of creation and activities of the Serbian Volunteer Corps formed from captured soldiers and officers of the Austro-Hungarian army inOdessain the Summer 1916. The same autumn it received a baptism of fire in Dobruja fighting in the separate corps of the Russian army under the command of General Zayonchkovsky. The research interest in studying the activities of “national” and "international" military units within the Russian army is connected with the question of expediency and effectiveness of using such forces against those for whom they have not so long ago shed blood. The author, contrary to the popular opinion of Serbian historians, shows that the call to join the First Serbian division did not arouse mass enthusiasm among the prisoners of war both Serbs and representatives of other Yugoslav nations because of well-founded fears for their close relatives living in the Dual Monarchy and a fairly comfortable stay in the Russian captivity. At the same time, the author emphasizes that this military unit, commanded by officers of the Serbian regular army, was considered by the political leadership ofSerbiaas the basis of the future armed forces of the new state ofYugoslavia. The article shows that the events of the Russian Revolution of 1917 influenced the future fate of this military formation. Many of its soldiers later found themselves on different sides of the front in the Russian civil war. A special attention is payed to the interethnic conflict erupted in the corps between the Serbs on the one side and the Croats and Slovenes on the other. The author introduces a significant body of primary documents showing the nuances of relations in the corps between representatives of various Yugoslav nations. The article emphasizes that the relationship of the Serbs, Croats and Slovenes within the

    2009-01-01

    Full Text Available This study explored why and how Russian speaking parents in an Irish context maintained the Russian language in their school-age children. Using a self-administered unstandardised questionnaire, the opinions of 16 Russian-speaking parents, reporting on 24 children, were surveyed. Of this sample, five parents were then interviewed using focus group methodology. The main findings revealed that Russian-speaking parents living in Ireland strongly supported Russian language maintenance in their families and wanted their children to be as fluent as possible in the Russian language. The reasons for the support of Russian language were: cultural preservation, general knowledge of languages in addition to English, and communication with the homeland. Methods employed to maintain the Russian language included conversing with children through Russian, reading and watching Russian TV/DVD. Although most parents spoke only Russian to their children, just three children were considered by their parents to have sufficient language skills to interact through Russian in Russian speaking countries. Interestingly, 15 children were thought to have adequate skills in Russian to speak with those outside their immediate family when in Ireland. Congruent with other studies of bilingualism, development of English, or the secondary, majority language, was also important to parents, as they lived in a dominant English-speaking society.

    In the material testing reactor BR2, the use of highly enriched uranium is determined by the consideration of the fast, epithermal and thermal neutron flux effectively available for the experimental devices. The choice of the core configuration is defined by combining the localisation of the experimental devices and of fuel elements of various burnup, such as to satisfy the irradiation conditions of the experimental load, compatible with an economic use of the fuel elements and safe operation of the reactor. Taking into account the present manufacturing technology for MTR fuels (37 Wt % uranium density in the fuel meat) the highly enriched uranium cannot be avoided; if higher concentration of uranium could be realised by some new manufacturing technology, the 235 U density of fuel elements at elimination should be kept at the required level and the enrichment could be reduced accordingly

    1984-01-01

    The Pajarito Monitor for Special Nuclear Material is a high-sensitivity gamma-ray monitoring system for detecting small quantities of highly enriched uranium transported by pedestrians or motor vehicles. The monitor consists of two components: a walk-through personnel monitor and a vehicle monitor. The personnel monitor has a plastic-scintillator detector portal, a microwave occupancy monitor, and a microprocessor control unit that measures the radiation intensity during background and monitoring periods to detect transient diversion signals. The vehicle monitor examines stationary motor vehicles while the vehicle's occupants pass through the personnel portal to exchange their badges. The vehicle monitor has four groups of large plastic scintillators that scan the vehicle from above and below. Its microprocessor control unit measures separate radiation intensities in each detector group. Vehicle occupancy is sensed by a highway traffic detection system. Each monitor's controller is responsible for detecting diversion as well as serving as a calibration and trouble-shooting aid. Diversion signals are detected by a sequential probability ratio hypothesis test that minimizes the monitoring time in the vehicle monitor and adapts itself well to variations in individual passage speed in the personnel monitor. Designed to be highly sensitive to diverted enriched uranium, the monitoring system also exhibits exceptional sensitivity for plutonium

    This report discusses each of the components that affect the unit cost for enriched uranium; that is, ore costs, U 3 O 8 to UF 6 conversion cost, costs for enriching services, and changes in transaction tails assay. Historical trends and announced changes are included. Unit costs for highly enriched uranium (93.15 percent 235 U) and for low-enrichment uranium (3.0, 3.2, and 3.5 percent 235 U) are displayed as a function of changes in the above components and compared. It is demonstrated that the trends in these cost components will probably result in significantly less cost increase for highly enriched uranium than for low-enrichment uranium--hence favoring the High-Temperature Gas-Cooled Reactor

    The concentration, occurrence, and geological origin of lead and selenium in the main minable coal seam from the Junger coalfield were studied using inductively coupled plasma mass spectrometry (CICP-MS), instrumental neutron activation analysis (CINAA), scanning electron microscope equipped with an energy-dispersive X-ray spectrometer (SEM-EDX), and optical microscope. The results show that the average concentrations of Pb and Se are as high as 35.7 {mu}g/g and 8.2 {mu}g/g, respectively, which are much higher than those of coals from North China, Guizhou, China, and USA. In addition, their enrichment factors are up to 2.4 and 68.1, respectively. Lead and selenium are significantly enriched in the seam. Lead and selenium mainly exist in galena, clausthalite, and selenio-galena which occur as cell-filling of coal-forming plants and are of chemical-sedimentary origin. 22 refs., 3 figs., 1 tab.

    Full Text Available The article analyzes the development of Russian-Saudi political interaction after the restoration (at that time of Soviet-Saudi relations of bilateral relations in September 1990. The article focuses on the role of the Russian Muslim community in shaping the Russian politics towards Riyadh in the 1990-2000s. The authors state there are both periods of “crises” and detente in the development of Russian-Saudi political interaction that were marked by events in Chechnya and former Yugoslavia in 1994-2000, “Arab Spring” 2011, the post-September 2015 era, the Russian anti-terrorist campaign in Syria. The alternation of these periods is the constant of Russian-Saudi political contacts, despite the similarity in the approaches of both sides to the ways and methods of solving crisis situations in the Middle East region, as well as the Saudi’s pro-Russian position regarding the change in the status of the Crimea and the situation in the east of Ukraine. The general attitude of both sides towards ISIS and Jabha al-Nusra as a source of terrorism, regional instability and the challenge of international security does not remove the two main contradictions that divide Moscow and Riyadh – attitude toward the official Syrian regime and the Iran’s regional policy. The study comes to the conclusion that Russia and Saudi Arabia are interested (albeit for various reasons in diversifying their foreign policy and foreign economic relations.

    Full Text Available The essay is focused on the spiritual crisis of Russian culture at the beginning of the 20th Century and on the search of philosophical alternatives to overcome the crisis within the framework of Russian philosophical thought. In particular, it highlights the work of Boris P. Vysheslavtzev, a major thinker among Russian immigrants and his studies in Russian folklore seen as reflection of Russian national character. The essay for the first time introduces new data concerning the specificity of the choice that was highly important for Russian literature and culture as it was for Russian folklore studies.

    Full Text Available On December 25, 2014 it would be twenty-one year since the Constitution of the Russian Federation was adopted on the national referendum on December 12, 1993. During this time, almost all constitutional provisions are implemented. The key point of course was the judicial reform in Russia, launched simultaneously with the adoption of Constitution of the Russian Federation. Adopted the new Civil Procedural Code, Criminal Procedural Code, Arbitration Procedural Code of the Russian Federation, Federal Constitutional Law "On the Constitutional Court of the Russian Federation", Federal Constitutional Law "On the courts of general jurisdiction in Russia", Federal Constitutional Law "On the Supreme Court of the Russian Federation". However, during twenty-one year of Russian Constitution work, the question on establishment of administrative courts in our country has not been resolved. Merger of the Supreme Court and the Supreme Arbitration Court of the Russian Federation, which happened in the year 2014, also shown the need to resolve the status of administrative courts in Russia. Previously submitted to the State Duma of the Federal Assembly of the Russian Federation the draft of the Federal Constitutional Law "On the Federal Administrative Courts in the Russian Federation" and is on the revision, which does not correspond to changes in the judicial system of the Russian Federation. Despite the failure of the Federal Constitutional Law "On the Federal Administrative Courts in the Russian Federation", in the opinion of the author, and it should be called that way, it Russia has already developed an own model of the Russian administrative justice, which is very specific.

    2016-12-01

    Full Text Available The article examines the position of Russians in Estonia and their relation with ethnic Estonians. The author analyzes models of the society integration introduced by Tallinn after 1991. The results raise questions regarding language education in Estonia, the proficiency level of Estonian is getting widely known by Russians, but on the other hand, there is still a significant part of the population that cannot communicate in Estonian. Those who have a good command of Estonian tend to be better integrated and to coexist with both Estonians and Russians. Russians living in Estonia are supposed to be equally involved in social and political life of the state. The potential of all residents has to be effectively and considerably used, especially when the number of population is decreasing. The position of Russians in Estonia is a major domestic and bilateral issue in the relations with the Russian Federation.

    Highlights: {yields} Enriched consortia were able to couple the anaerobic degradation of benzene to the reduction of humic acids. {yields} Electron-equivalents derived from anaerobic benzene oxidation were highly recovered as reduced humic acids. {yields} Several species from classes {beta}-, {delta}- and {gamma}-Proteobacteria were enriched during the anaerobic degradation of benzene. - Abstract: The anaerobic degradation of benzene coupled to the reduction of humic acids (HA) was demonstrated in two enriched consortia. Both inocula were able to oxidize benzene under strict anaerobic conditions when the humic model compound, anthraquinone-2,6-disulfonate (AQDS), was supplied as terminal electron acceptor. An enrichment culture originated from a contaminated soil was also able to oxidize benzene linked to the reduction of highly purified soil humic acids (HPSHA). In HPSHA-amended cultures, 9.3 {mu}M of benzene were degraded, which corresponds to 279 {+-} 27 micro-electron equivalents ({mu}Eq) L{sup -1}, linked to the reduction of 619 {+-} 81 {mu}Eq L{sup -1} of HPSHA. Neither anaerobic benzene oxidation nor reduction of HPSHA occurred in sterilized controls. Anaerobic benzene oxidation did not occur in soil incubations lacking HPSHA. Furthermore, negligible reduction of HPSHA occurred in the absence of benzene. The enrichment culture derived from this soil was dominated by two {gamma}-Proteobacteria phylotypes. A benzene-degrading AQDS-reducing enrichment originated from a sediment sample showed the prevalence of different species from classes {beta}-, {delta}- and {gamma}-Proteobacteria. The present study provides clear quantitative demonstration of anaerobic degradation of benzene coupled to the reduction of HA.

    Full Text Available Contribution of outstanding Russian surgeons (Pirogov N.I., Inozemcev F.I., Bobrov A.A., Lezhnev N.F., Fyodorov S.P. and their pupils to thyroid surgery is not fully appreciated yet. Dr. N.I. Pirogov (1831 described the major principles of thyroid anatomy, topography, syntopy and surgery. In 1847, he performed the first strumectomy in Russia with a detailed description of the technique and the outcome. It was also the first surgery on the thyroid in the world performed under general anesthesia. In 1904, Russian surgeon N.F. Lezhnev (Moscow reported on 106 thyroid surgeries using visual control of recurrent laryngeal nerves in A.A. Bobrov’s clinic since 1893. V.I. Razumovsky was the first to describe medullary and anaplastic carcinoma of the thyroid in 1904. He also recommended laryngoscopy in all patients prior to the surgery. S.P. Fyodorov - Professor of Imperial Military Medical Academy in Saint-Petersburg, was extremely reputable in Europe, he was also interested in ectopic goiter, and lingual goiter. When W. Mayo saw Dr. Fyodorov’s surgical skills he called him “Master of Surgery” and invited Fyodorov to become Surgeon-in-Chief at the Mayo Clinic. Recent political changes opened new opportunities for a more effective cooperation between surgeons throughout the world.

    2008-07-01

    Full Text Available One of peculiar features of the military criminal justice system in Russia is that in some cases military defendants may apply for trial by jury. Unlike the existing U.S. court-martial jury and the Russian military jury of the early 1900s (World War I period which were comprised of the members of the armed forces, in modern Russia jurors trying military defendants are civilians. This article aims to provide a brief history of military jury in Russia and identify issues of independence and impartiality in Russian military courts with participation of lay decision-makers. In particular, the article will analyze two high-profile cases which resulted in acquittals of Russian officers accused of killing several Chechen civilians during counter-terrorist operations in Chechnya.

    2000-04-01

    Highly enriched nitrogen-15 gas is favorable to reduce radioactive carbon-14 production in reactor. The cost of highly enriched nitrogen-15 gas in mass production is one of the most important subject in nitride fuel option in 'Feasibility Study for FBR and Related Fuel Cycle'. In this work gas phase adsorption technology was verified to be applicable for nitrogen isotope separation and feasible to produce highly enriched nitrogen-15 gas in commercial. Nitrogen isotopes were separated while ammonia gas flows through sodium-A type zeolite column using pressure swing adsorption process. The isotopic ratio of eight samples were measured by high resolution mass spectrometry and Fourier transform microwave spectroscopy. Gas phase adsorption technology was verified to be applicable for nitrogen isotope separation, since the isotopic ratio of nitrogen-15 and nitrogen-14 in samples were more than six times as high as in natural. The cost of highly enriched nitrogen-15 gas in mass production were estimated by the factor method. It revealed that highly enriched nitrogen-15 gas could be supplied in a few hundred yen per gram in mass production. (author)

  10. Russian nuclear industry exports

    International Nuclear Information System (INIS)

    Gorbatchev, A.

    2016-01-01

    Rosatom is the world leader for the export of nuclear technologies. 34 reactors of Russian technology are being built or planned worldwide. Most reactors proposed by Rosatom are third generation VVER-1200 units with an electric power output of 1200 MWe. Although the nuclear island is always built by Rosatom, the remain of the plant can be subcontracted to other enterprises and European companies are sought because they would bring a european quality touch to Russian works. One of the main assets of Rosatom is to propose an integrated offer from supplying nuclear fuel to managing nuclear waste via the turnkey building of nuclear power plants. Another important asset is the financial assistance of the Russian state through state credit or the support from Russian national banks that appears to be a decisive advantage in the international competition to win markets. We have to temper the Russian export perspectives by noting that most projects are set in countries that are prone to instabilities and that the economic crisis affecting Russia has a negative impact on its financial means.

    Information on e-cigarettes among youth in the Russian Federation is lacking. We examined prevalence of and factors associated with youth e-cigarette use in the Russian Federation. A cross-sectional, anonymous survey, conducted among 716 (females 51.5%) high school students in three cities (i.e., Ufa, Sterlitamak, Karagaevo) within the Republic of Bashkortostan, Russian Federation in 2015, assessed e-cigarette use and its correlates (i.e., sex, age, ethnicity, family structure, parents' highest degrees, antisocial behaviors, stress coping strategies, lifetime cigarette, hookah, alcohol, and marijuana use). Lifetime use of e-cigarettes was 28.6% and past-30-day use was 2.2%. Multilevel modeling showed that belonging to Tatar/Bashkir ethnicity relative to Russian ethnicity (OR = 1.60) and lifetime use of cigarettes (OR = 21.64), hookah (OR = 4.21), and alcohol (OR = 1.90) was associated with greater odds of lifetime use of e-cigarettes. Furthermore, use of social support coping strategies (i.e., utilizing parents for support) were associated with lower odds of lifetime use of e-cigarettes (OR = 0.94). Despite high lifetime e-cigarette use, past-30-day use was low. Greater knowledge of the reasons for e-cigarette discontinuation through continued surveillance is needed in the Russian Federation. Social coping strategies involving parents may inform e-cigarette use prevention.

  13. Target-dependent enrichment of virions determines the reduction of high-throughput sequencing in virus discovery.

    Directory of Open Access Journals (Sweden)

    Randi Holm Jensen

    Full Text Available Viral infections cause many different diseases stemming both from well-characterized viral pathogens but also from emerging viruses, and the search for novel viruses continues to be of great importance. High-throughput sequencing is an important technology for this purpose. However, viral nucleic acids often constitute a minute proportion of the total genetic material in a sample from infected tissue. Techniques to enrich viral targets in high-throughput sequencing have been reported, but the sensitivity of such methods is not well established. This study compares different library preparation techniques targeting both DNA and RNA with and without virion enrichment. By optimizing the selection of intact virus particles, both by physical and enzymatic approaches, we assessed the effectiveness of the specific enrichment of viral sequences as compared to non-enriched sample preparations by selectively looking for and counting read sequences obtained from shotgun sequencing. Using shotgun sequencing of total DNA or RNA, viral targets were detected at concentrations corresponding to the predicted level, providing a foundation for estimating the effectiveness of virion enrichment. Virion enrichment typically produced a 1000-fold increase in the proportion of DNA virus sequences. For RNA virions the gain was less pronounced with a maximum 13-fold increase. This enrichment varied between the different sample concentrations, with no clear trend. Despite that less sequencing was required to identify target sequences, it was not evident from our data that a lower detection level was achieved by virion enrichment compared to shotgun sequencing.

    A method and apparatus for improving the performance of a thermal breeder reactor having regions of higher than average moderator concentration are disclosed. The fuel modules of the reactor core contain at least two different types of fuel elements, a high enrichment fuel element and a low enrichment fuel element. The two types of fuel elements are arranged in the fuel module with the low enrichment fuel elements located between the high moderator regions and the high enrichment fuel elements. Preferably, shim rods made of a fertile material are provided in selective regions for controlling the reactivity of the reactor by movement of the shim rods into and out of the reactor core. The moderation of neutrons adjacent the high enrichment fuel elements is preferably minimized as by reducing the spacing of the high enrichment fuel elements and/or using a moderator having a reduced moderating effect. 1 figure

    The continuous enrichment monitor, developed and fielded in the 1990s by the International Atomic Energy Agency, provided a go-no-go capability to distinguish between UF 6 containing low enriched (approximately 4% 235 U) and highly enriched (above 20% 235 U) uranium. This instrument used the 22-keV line from a 109 Cd source as a transmission source to achieve a high sensitivity to the UF 6 gas absorption. The 1.27-yr half-life required that the source be periodically replaced and the instrument recalibrated. The instrument's functionality and accuracy were limited by the fact that measured gas density and gas pressure were treated as confidential facility information. The modern safeguarding of a gas centrifuge enrichment plant producing low-enriched UF 6 product aims toward a more quantitative flow and enrichment monitoring concept that sets new standards for accuracy stability, and confidence. An instrument must be accurate enough to detect the diversion of a significant quantity of material, have virtually zero false alarms, and protect the operator's proprietary process information. We discuss a new concept for advanced gas enrichment assay measurement technology. This design concept eliminates the need for the periodic replacement of a radioactive source as well as the need for maintenance by experts. Some initial experimental results will be presented.

The core conversion to LEU is being performed with financial support from the U. S. government. In the framework of non-proliferation policies, the international community presently aims to minimize the amount of nuclear material available that could be used for nuclear weapons. In this geopolitical context most research and test reactors, both domestic and international, have started a program of conversion to the use of LEU fuel. A new type of LEU fuel based on an alloy of uranium and molybdenum (U-Mo) is expected to allow the conversion of U.S. domestic high performance reactors like MURR. This report presents the results of a study of core behavior under a set of accident conditions for MURR cores fueled with HEU U-Alx dispersion fuel or LEU monolithic U-Mo alloy fuel with 10 wt% Mo

    The Foton-M3 spacecraft launched from Baikonur Cosmodrome (Kazakhstan) on 14 September 2007 and landed 12 days later approximately 130 km south of Kustanay, Northern Kazakhstan. Following the successful National Aeronautics and Space Administration (NASA) and Institute for Biomedical Problems (IMBP) collaboration on the Russian Foton-M2 spaceflight (June 2005), IMBP invited NASA to continue and broaden its participation in four Russian biomedical studies on the Foton-M3 spaceflight. Where the Foton-M2 collaboration had been accomplished without an exchange of funds, the basis for the ongoing bilateral interaction on Foton-M3 was both a cooperative Space Act Agreement and a NASA contract with IMBP. As in Foton-M2, NASA scientists agreed to focus their efforts on research that would be complementary and would facilitate the accomplishment of the original Russian science goals. Foton-M3 hardware enhancements included NASA inserts installed in the IMBP flight hardware to provide programmable in-flight video recording for newts and geckos, drinking water for the geckos, and a preflight "shower" of Bromodeoxyuridine (BrdU) for the newts.

    International Journals have built-in tools for saving citations to reference manager software. The majority of articles in Russian journals cannot be captured by citation management systems: they do not have special coding of articles descriptors.c. Some journals still have PDF files of the whole journal issue without dividing it into articles and do not provide any descriptors, making manual time-consuming input of information the only possibility. Moreover the context search of the article content is unavailable for search engines.2) The quality of research. This problem has been discussed for more than twenty years already. Still we have too many publications of poor quality of study design and statistical analysis. With the exception of pharmacological clinical tails, designed and supervised by international Pharma industry, many interventional studies, conducted in Russia, have methodological flaws inferring a high risk of bias:a. Absence of adequate control,b. No standard endpoints, duration of therapy and follow up,c. Absence of randomization and blinding,d. Low power of studies: sample sizes are calculated (if calculated at all) in such a way, that the main goal is to have as small sample size as possible.

    During the mid-1970s, there was increasing concern with the possibility that highly enriched uranium (HEU), widely used in non-power reactors around the world, might be diverted from its intended peaceful uses. In 1982 the U.S. Nuclear Regulatory Commission (NRC) issued a policy statement that was intended to conform with the perceived international thinking, and that addressed the two relevant areas in which NRC has statutory responsibility, namely, export of special nuclear materials for non-USA non-power reactors, and the licensing of USA-based non-power reactors not owned by the Federal government. To further address the second area, NRC issued a proposed rule for public comment that would require all NRC-licensed non-power reactors using HEU to convert to low enriched uranium (LEU) fuel, unless they could demonstrate a unique purpose. Currently the NRC staff is revising the proposed rule. An underlying principle guiding the staff is that as long as a change in enrichment does not lead to safety-related reactor modifications, and does not involve an unreviewed safety question, the licensee could convert the core without prior NRC approval. At the time of writing this paper, a regulatory method of achieving this principle has not been finalized. (author)

    Full Text Available The effective collaboration between the Russian Federation and Germany at the beginning of the 21st century would be impossible without mutually beneficial economic cooperation of the two countries. The analysis of basic stages in the economic relations, achievements and problems are considered by the author to be important for lining-up an all-round picture of the Russian-German relations in the period under review. The main purpose of this article is the consideration and analysis of the economic aspects in the Russian foreign policy towards Germany. The problem considered in the article is of current importance, because in 2000-2013 the economic collaboration of Russia and the German Federal Republic was brought to a high level, but at the same time some considerable potential of cooperation was not fulfilled. With regard to complementarity of the Russian and German economies and their centuries-old experience of collaboration and mutual financial interest, it is possible to suppose that the economic sphere in particular would be a basis of optimization of the Russian-German relations in the long term. In such a way, this article deals with the basic directions of the Russian-German economic cooperation in 2000-2013.The contractual legal base of financial relations is examined with the purpose to reveal strengths and weaknesses as well as perspective possibilities of the optimization in the Russian-German relations in the future.

    An NEA study on safety research needs of Russian-designed reactors, carried out in 1996, strongly recommended that a strategic plan for safety research be developed with respect to Russian nuclear power plants. Such a plan was developed at the Russian International Nuclear Safety Centre (RINSC) of the Russian Ministry of Atomic Energy (Minatom). The Strategic Plan is designed to address high-priority safety-research needs, through a combination of domestic research, the application of appropriate foreign knowledge, and collaboration. It represents major progress toward developing a comprehensive and coherent safety-research programme for Russian nuclear power plants (NPPs). The NEA undertook its review of the Strategic Plan with the objective of providing independent verification on the scope, priority, and content of the research described in the Plan based upon the experience of the international group of experts. The principal conclusions of the review and the general comments of the NEA group are presented. (K.A.)

    A brief overview of the radioactive waste inventory of the 'Mayak' PA reprocessing plant, Chelyabinsk Region, Russia is given together with a description of the environmental contamination caused by its activities and the origins of contamination. The joint Russian-Norwegian field work in 1994 is described, together with the major analytical results. The field work was of a limited extent, and was not designed to include a complete mapping of the environmental contamination around the plant. The results are, however, in good agreement with the very extensive previous Russian investigations. The highest concentrations of radioactivity were found in Reservoirs 10 and 11 and at the floodplain of the upper Techa River (Asanov Swamp). Also high concentrations are found in biota, especially fish from Reservoir 10.

    Language and culture relate in complex ways. Addressing this complexity in the context of language translation is a challenge when caring for patients with limited English proficiency (LEP). To examine processes of care related to language, culture and translation in an LEP population is the objective of this study. We used community based participatory research to examine the experiences of Russian-speaking cancer patients in San Francisco, California. A Russian Cancer Information Taskforce (RCIT), including community-based organizations, local government, and clinics, participated in all phases of the study. A purposeful sample of 74 individuals were the participants of the study. The RCIT shaped research themes and facilitated access to participants. Methods were focus groups, individual interviews, and participant observation. RCIT reviewed data and provided guidance in interpreting results. Four themes emerged. (1) Local Russian-language resources were seen as inadequate and relatively unavailable compared to other non-English languages; (2) a taboo about the word "cancer" led to language "games" surrounding disclosure; (3) this taboo, and other dynamics of care, reflected expectations that Russian speakers derived from experiences in their countries of origin; (4) using interpreters as cultural brokers or establishing support groups for Russian speakers could help address barriers. The language barriers experienced by this LEP population reflect cultural and linguistic issues. Providers should consider partnering with trained interpreters to address the intertwining of language and culture.

    Full Text Available The value of multinational enterprises (MNEs as the main players in the global economy is constantly increasing. More and more companies from developing and transition economies are starting to do business beyond their national borders. Not all of them strictly belong to the category of MNEs, as is the case for Russia’s largest companies. This article analyzes the international activities of Russian MNEs. The authors study the place of MNEs in the modern world and examine the transformation of the concept of an MNE in the international practice. They identify the internationally accepted criteria that classify a company as an MNE. They analyze the international activities of the largest Russian companies in the oil and gas sector (Gazprom, Rosneft, Lukoil, Surgutneftegas, Novatek and their possible classification as MNEs. The article also assesses the influence of the economic and political sanctions on the international activities of Russian MNEs in the oil and gas sector. The methodological basis for the study is the dialectical method of investigating phenomena and processes in the modern world as the most effective way to achieve goals. The authors pay particular attention to the practical application of comparative economic analysis, classification and empirical generalization of original data. The authors came to seven conclusions. First, there is no single approach to defining the essence of MNEs. Second, the indicators that classify a company as an MNE can be divided into qualitative and quantitative criteria. Third, not all the large companies in Russia engaged in expanding into foreign markets can be classified as MNEs by the formal criteria. Fourth, most Russian MNEs have an unstable position in international ratings of MNEs, with the exception of Lukoil. Fifth, the main problems of Russian MNEs include the inefficiency of foreign assets, the lack of experience in managing international holdings and the longstanding crisis of the

    The Institute of Physics and Power Engineering (IPPE) is a leading research center under the Ministry of Atomic Energy of the Russian Federation. IPPE encompasses many installations and many specialists who perform fundamental and applied investigations in nuclear power and technology for the national nuclear program. IPPE has a key role in the national nuclear material protection, control, and accounting (MPC ampersand A) system both as a nuclear facility and also as a training center for MPC ampersand A. As a participant in the US-Russian Laboratory-to-Laboratory Cooperative Program in MPC ampersand A, IPPE is conducting several tasks in collaboration with US Department of Energy national laboratories. The main goal of these tasks is the rapid improvement of MPC ampersand A at one of the most sensitive operating IPPE installations, the BFS critical facility, which has large numbers of fuel items containing highly enriched uranium and weapons-grade plutonium. After the completion of several test, evaluation, and demonstration tasks, it is hoped that the tested and adopted methods and procedures can be applied not only to the entire population of BFS fuel items, but also to other facilities at IPPE and other Russian nuclear institutes and operating facilities. The collaborative tasks cover seven areas: computerized nuclear material accounting, entry control and portals, item control and inventory, design evaluation and analysis, gamma and neutron assay, an integrated demonstration, and physical protection elements and test bed

    2011-02-01

    Screening large numbers of target regions in multiple DNA samples for sequence variation is an important application of next-generation sequencing but an efficient method to enrich the samples in parallel has yet to be reported. We describe an advanced method that combines DNA samples using indexes or barcodes prior to target enrichment to facilitate this type of experiment. Sequencing libraries for multiple individual DNA samples, each incorporating a unique 6-bp index, are combined in equal quantities, enriched using a single in-solution target enrichment assay and sequenced in a single reaction. Sequence reads are parsed based on the index, allowing sequence analysis of individual samples. We show that the use of indexed samples does not impact on the efficiency of the enrichment reaction. For three- and nine-indexed HapMap DNA samples, the method was found to be highly accurate for SNP identification. Even with sequence coverage as low as 8x, 99% of sequence SNP calls were concordant with known genotypes. Within a single experiment, this method can sequence the exonic regions of hundreds of genes in tens of samples for sequence and structural variation using as little as 1 μg of input DNA per sample.

    After five years experience in bringing American students to meet and learn with Russian students in Kamchatka and bringing Russian students to meet and learn with American students in Alaska, it is possible to make some generalizations about the problems and benefits this growing program. Some 200 students, including many from other countries besides the United States and Russian Federation, have now had this experience. The context of their collaboration is the International Volcanological Field School, sponsored by the University of Alaska Fairbanks, Kamchatka State University, and the Institute of Volcanology and Seismology, and also a comparison of Mount St Helens, Bezymianny, and Shiveluch volcanoes under the National Science Foundation's Partnerships in International Research in Education, with important support from the Russian Academy of Sciences, Far East Division. Elements of these two projects are adaptation to unfamiliar, harsh, and remote environments; intensive courses in Russian language, history, geography, and culture; and sharing of research and education experiences among students. The challenges faced by the program are: · Slow and complex visa processes. · Demise of a direct airline connection, necessitating round-the-world travel to go 3000 km. · Adequately communicating to students beforehand the need for physical fitness, mental fortitude in uncomfortable conditions, and patience when bad weather limits mobility. Benefits of the projects have been: · Experiences that students report to be career- and life-changing. · Much more positive perceptions of Russia and Russian people by American students and of America and Americans by Russian students. · Introduction to the "expedition style" volcanology necessary in challenging environments. · Development of long-lasting collaborations and friendships in the context of international science. Students often comment that hearing about what their peers have done or are doing in research at

    Breeding for resistance against Russian wheat aphid in Kenya is reported. Results of six of the lines were found to have high to moderate resistance to Russian wheat aphid. Popular lines were susceptible in the greenhouse when subjected to aphid pressure but showed moderate susceptibility when screened under field conditions, indicating that in years or location with low aphid pressure farmers may still get a crop. However in areas of high aphid pressure or bad years they may lose their crop. Consequently, developing resistant/torerant varieties is urgent

The paper aims to estimate the volume and dynamics of Russian capital inflows into Latvia in compliance with Russian economic interests; to identify key sectors of Latvian economy that Russian capital is interested to invest in; to systemize information concerning Russian firms investing in Latvia; to assess the role of Russian capital in Latvian economy in comparison with other foreign investors; to propose author’s view on challenges and perspectives of Latvian-Russian investment cooperation in the situation of economic sanctions and geo-political conflict in east Ukraine. The author underlines that at the end of 2013, investments of Russian business to Latvia constituted about 5.0% of the total FDI stock and by that time Russia was the 7th largest investor with 0.5 bln euro of capital invested. The main sectors of Russian interests in Latvia are - gas supply, transport communications (transit corridors, banking and real estate. The article concludes that though the future of Russian-Latvian economic relations in the short-run is on a substantial pressure of geopolitical factors, the economic interests in mutual investment relations will prevail in the long-run perspectives.

    Full Text Available In this paper, actual problems of innovative-technological image as a key element of the mechanism of the healing sources of socioeconomic development of the Russian regionsare considered. The author gives an assessment of the level of differentiation of subjects of the Russian Federation on the potential for innovative development. Trends in spatial transformations of thescientific and technical and innovation capacities of the country are analyzedand reasons of low innovational activity of Russian enterprises are disclosed. Basic conditions for the success of actions to create an attractive image of innovative-technological territory are formulated. Special attention is paid to the position of regions as participants in the innovational processes, creating preconditions for creativity, harmonization of spatial priorities of innovation, technological and socio-economic development, support for the development of new high-tech industries, improvement of inter-budgetary relations. There are proved priority areas of state policy to reduce barriers to the realization of an innovative paradigm for development of Russian society and effective inclusion of local communities in the implementation of innovative changes.

    Full Text Available This article examines the commodification of Russian in Finland, where recent decades have seen a sharp rise in the size of the Russian-speaking population and the number of tourists from Russia. We particularly consider the use of Russian in the fields of traditional and medical tourism, education, and culture - all of them areas where Russian tourists show a strong preference for services in their native language. The need to provide a variety of services in Russian means that proficiency in Russian is a sig-nificant asset on the job market, both for immigrants and for the relatively small number of Finns who can speak the language. We also note that there is considerable demand among Russian-speaking parents in Fin-land for educational services to supplement their children’s school education.

    The GT-MHR reactor (Gas Turbine Modular Helium Reactor) aims the double objective to eliminate the Russian plutonium coming from weapons, ( until 3 tons by year) and to produce a competitive energy from a small-scale power reactor with a nuclear fuel that can be of different type (plutonium or uranium). This reactor has several advantages: a high yield (47%) as every high temperature reactor and to be used in combined cycle, a high level of safety because of its ability to evacuate the residual power in a totally passive way and because of the nature of its fuel that is made of ceramics with a very high melting point that is to say no possibility of core melt. The fission products are contained in the ceramics so that reactor cannot disseminate radioactivity in its structure and consequently does not induce irradiation for the personnel. (N.C.)

    2007-10-01

    Full Text Available In a region that is traditionally considered to be transnational, Nordic cinema has often posed as the prime case for a transnational cinema. The paper contests this notion of Nordic transnationality by analysing two films that depict two Russian women travelling to Sweden. Interdevochka/Intergirl (Todorovski, 1989, USSR and Lilya-4-ever (Moodysson, 2004, Sweden challenge the inclusiveness of the region and make explicit the fact that Russian identities are not part of the homogenous mixture of the region. Instead, Russian identities of cross-border prostitution are cinematically subjected to rejection and victimisation. This paper examines how Lilya-4-ever adheres to a European anxiety narrative by performing a Russian return narrative and how Interdevochka/Intergirl portrays ‘the fallen soviet woman’ by travelling to Sweden. These cinematic representations of the female Russian identity travelling to Sweden differ from each national context, but by probing into a comparative analysis the paper will reveal that both films need the Other to narrate these stories of transnational labour migration.

  3. On Russian concepts of Soil Memory - expansion of Dokuchaev's pedological paradigm

    Tsatskin, A.

    2012-04-01

    Having developed from Dokuchaev's research on chernosem soils on loess, the Russian school of pedology traditionally focused on soils as essential component of landscape. Dokuchaev's soil-landscape paradigm (SLP) was later considerably advanced and expanded to include surface soils on other continents by Hans Jenny. In the 1970s Sokolov and Targulian in Russia introduced the new term of soil memory as an inherent ability of soils to memorize in its morphology and properties the processes of earlier stages of development. This understanding was built upon ideas of soil organizational hierarchy and different rates of specific soil processes as proposed by Yaalon. Soil memory terminology became particularly popular in Russia which is expressed in the 2008 multi-author monograph on soil memory. The Soil Memory book edited by Targulian and Goryachkin and written by 34 authors touches upon the following themes: General approaches (Section 1), Mineral carriers of soil memory (Section 2), Biological carriers of soil memory (section 3) and Anthropogenic soil memory (section 4). The book presents an original account on different new interdisciplinary projects on Russian soils and represents an important contribution into the classical Dokuchaev-Jenny SL paradigm. There is still a controversy as to in what way the Russian term soil memory is related to western terms of soil as a record or archive of earlier events and processes during the time of soil formation. Targulian and Goryachkin agree that all of the terms are close, albeit not entirely interchangeable. They insist that soil memory may have a more comprehensive meaning, e.g. applicable to such complex cases when certain soil properties whose origin is currently ambiguous cannot provide valid environmental reconstructions or dated by available dating techniques. Anyway, not terminology is the main issue. The Russian soil memory concept advances the frontiers of pedology by deepening the time-related soil functions and

    Launch into education about pharmacology (LEAP) is an inquiry-based science enrichment program designed to enhance competence in biology and chemistry and foster interest in science careers especially among under-represented minorities. The study of how drugs work, how they enter cells, alter body chemistry, and exit the body engages students to conceptualize fundamental precepts in biology, chemistry, and math. Students complete an intensive three-week course in the fundamentals of pharmacology during the summer followed by a mentored research component during the school year. Following a 5E learning paradigm, the summer course captures student interest by introducing controversial topics in pharmacology and provides a framework that guides them to explore topics in greater detail. The 5E learning cycle is recapitulated as students extend their knowledge to design and to test an original research question in pharmacology. LEAP students demonstrated significant gains in biology and chemistry knowledge and interests in pursuing science. Several students earned honors for the presentation of their research in regional and state science fairs. Success of the LEAP model in its initial 2 years argues that coupling college-level coursework of interest to teens with an authentic research experience enhances high school student success in and enthusiasm for science.

Institute Works in two main directions: 1) development of new high-density fuels (HDF) and 2) development of new design of fuel elements with LEU. The development of the new type fuel element is carried out both for existing reactors, and for developing new advanced reactors. The 'TVEL' concern is coordinator of works of this program. The majority enterprises of branch (NIIAR, PIYaF, RRC KI, NZChK) take part in this work. Since 2000 these works are being conducted in cooperation with Argonne National Laboratory (USA) within the RERTR program under VNIINM with ANL contract. At the present, a large set of pre-pile investigations has been completed. All necessary fabrication procedures have been developed for utilization of U-Mo dispersion fuel in Russian-designed research reactors. For irradiation tests the pin-type mini-fuel elements with HDF dispersion fuel with LEU and the uranium density equaled to 4,0 and 6,0 g/cm 3 (up to 40 vol.%) have been manufactured. Their irradiation began in August 2003 in the MIR reactor (NIIAR, Dimitrovgrad). A large set of works for preparation of lifetime tests (WWR-M reactor in Gatchina) of two full-scale fuel assemblies with new pin-type fuel elements on basis LEU UO 2 -Al and UMo-Al fuels has been completed. The in-pile tests of fuel assemblies began in September 2003. The summary of important results of performed works and their near-term future are presented in paper. (author)

    Full Text Available The structure of their future presidents’ images among Russian and American students was studied. The general tendencies and specific features of the perception of a future president among Russian and American students were revealed. For respondents of both groups, the significant factors influencing their choice of whom to vote for were the program of the candidate, his strategic thinking, the reliability of his team, a high degree of professionalism and competence, leadership skills, the ability to speak and convince, and personal qualities. In regard to specific features, Russian students paid more attention to the business qualities of a future president than did American students; Russian students were optimistic and considered elections capable of effecting changes in the country. American students showed less interest in political events, along with the professional qualities of the leader; they paid attention to his appearance and believed that elections can affect the private life of people.

    1999-01-01

    The objective of this work was to analyze instrumentation and methodologies used at Russian nuclear facilities for measurement of item nuclear materials, materials in bulk form, and waste streams; specify possibilities for the application of accounting measurements; and develop recommendations for improvement. The major steps and results: Representative conversion, enrichment (gas centrifuge), fuel fabrication, spent fuel reprocessing, and chemical-metallurgical production facilities in Russia were selected; Full lists of nuclear materials were prepared; Information about measurement methods and instrumentation for each type of nuclear material were gathered; and Recommendations on methodological and instrumentation support of accounting measurements for all types of materials were formulated. The analysis showed that the existing measurement methods and instrumentation serve mostly to support the technological process control and nuclear and radiation safety control. Requirements for these applications are lower than requirements for MC and A applications. To improve the state of MC and A at Russian nuclear facilities, significant changes in instrumentation support will be required, specifically in weighing equipment, volume measurements, and destructive and non-destructive analysis equipment, along with certified reference materials

  10. Soviet/Russian-American space cooperation

    Karash, Yuri Y.

    This dissertation seeks to answer two questions: (1) what are the necessary conditions for the emergence of meaningful space cooperation between Russia and the United States, and (2) might this cooperation continue developing on its own merit, contributing to the further rapprochement between the two countries, even if the conditions that originated the cooperation were to change? The study examines the entire space era up to this point, 1957 to 1997, from the first satellite launch through the joint U.S.-Russian work on the ISS project. It focuses on the analysis of three distinct periods of possible and real cooperation between the United States and the Soviet Union/Russia. The first possibility for a limited Soviet-American cooperation in space emerged in the late 1950s, together with the space age, and continued until the mid-1960s. The major potential joint project of this period was a human expedition to the Moon. The global competition/confrontation between the two countries prevented actual cooperation. The second period was from the late 1960s until 1985 with consideration of experimental docking missions, including the docking of a reusable U.S. shuttle to a Soviet Salyut-type station. The global U.S.-Soviet competition still continued, but the confrontation was replaced by detente for a brief period of time lasting from the end of 1960s until mid-1970s. Detente gave the first example of U.S.-Soviet cooperation in space---the Apollo-Soyuz joint space flight (ASTP) which took place in 1975. However, the lack of interest of political leaderships in continuation of broad-scale cooperation between the two countries, and the end of detente, removed ASTP-like projects out of question at least until 1985. The third period started together with Mikhail Gorbachev's Perestroika in 1985 and continues until now. It involves almost a hundred of joint space projects both at the governmental and at the private sectors levels. The mainstream of the joint activities

    Large-scale enrichment of uranium has now been carried out for 40 years. While the gaseous diffusion process was the original choice of several countries and continues today to provide the major component of the world production of separative work, the last two decades have witnessed the development of a number of alternative processes for enrichment. These processes, which are being studied and deployed around the world, offer a wide range of technical and economic characteristics which will be useful in assuring adequate capacity to meet projected reactor fuel market needs through the rest of this century at competitive prices. With present uncertainties in future enriched uranium needs, it is apparent that flexibility in the deployment and operation of any enrichment process will be one of the prime considerations for the future. More economical production of separative work not only can have a beneficial impact on reactor fuel costs, but also tends to conserve natural uranium resources. This paper reviews the world scene in the enrichment component of the fuel cycle, including existing or planned commercial-scale facilities and announced R+D efforts on various processes. (author)

  14. Ukrainian-Russian Mixed Speech “Suržyk” within the System of Ukrainian and Russian Interaction

    Full Text Available The question of different forms of real and/or presumed mixed speech, a consequence of the interaction between Ukrainian and Russian and widely known as “Suržyk,” remains central in much of contemporary Ukrainian and, more widely, East Slavic sociolinguistic and language contact research. This article pursues a twofold aim: first, I intend to reaffirm my personal hypothesis on the formation process of this mixed speech, which has at times been cited without attribution in the scholarly literature. Second, the paper aims to examine the functioning of Ukrainian-Russian Suržyk within a broader sociolinguistic framework that takes into account other forms of language interaction. Ukrainian-Russian mixed speech in fact has to be assessed and separated from other factors, such as the Ukrainian variety of Russian, dialects, etc. This approach has rarely been applied in previous studies on the topic. The role played by current language ideology is a further essential aspect in establishing which language elements should be attributed to Ukrainian-Russian Suržik. This undoubtedly affects the average speaker’s judgment about the degree of authenticity of Ukrainian forms. One can note a tendency to restrict the synonymic potential of Ukrainian in favor of lexemes and constructions that are dissimilar to Russian. This situation tends to alter the language consciousness of younger generations of Ukrainian speakers, who are likely to perceive as Russian (and therefore part of the Ukrainian-Russian mix elements that are in fact authentic Ukrainian speech elements. These and other related aspects will be the object of my discussion.

    Methanotrophic-heterotrophic communities were selectively enriched from sewage sludge to obtain a mixed culture with high levels of poly-β-hydroxybutyrate (PHB) accumulation capacity from methane. Methane was used as the carbon source, N 2 as sole nitrogen source, and oxygen and Cu content were varied. Copper proved essential for PHB synthesis. All cultures enriched with Cu could accumulate high content of PHB (43.2%-45.9%), while only small amounts of PHB were accumulated by cultures enriched without Cu (11.9%-17.5%). Batch assays revealed that communities grown with Cu and a higher O 2 content synthesized more PHB, which had a wider optimal CH 4 :O 2 range and produced a high PHB content (48.7%) even though in the presence of N 2 . In all methanotrophic-heterotrophic communities, both methanotrophic and heterotrophic populations showed the ability to accumulate PHB. Although methane was added as the sole carbon source, heterotrophs dominated with abundances between 77.2% and 85.6%. All methanotrophs detected belonged to type II genera, which formed stable communities with heterotrophs of different PHB production capacities. Copyright © 2017. Published by Elsevier B.V.

  16. Western values and the Russian energy weapon

    Science.gov (United States)

    Domingues, Bennett K.

    This thesis explores the competition between Russia and the West for the oil and gas resources of the Caspian Sea region, an area where far more is at stake than simply acquisition of new energy supplies. Ultimately, the "winner" of the competition for Caspian Sea energy resources will determine whether Russia will become the primary energy supplier for Europe in the future, or whether there will be alternative, non-Russian energy routes from East to West. The thesis uses a qualitative approach, drawing on scholarly books and articles, current affairs publications, energy firm websites, and other sources to compare the ethical aspects of the strategies used by Russia and the West, to determine whose strategy has been more successful, and to analyze what this means for the political, economic, and security future of Europe. As this thesis demonstrates, Russia recognizes the importance of energy as both an economic and foreign policy tool. To secure access to the resources of the Caspian Sea region, Russia has used bribery and strongman tactics to secure arrangements and contracts favorable to Russian interests. When a country does not capitulate to these tactics, Russia applies other measures to influence these countries' policies. This thesis draws on two recent examples, Ukraine and Georgia, to demonstrate how Russia has used its position as a supplier of energy resources to influence countries to adopt policies complementary to Russian interests, or to punish them for failing to do so. The effectiveness of these Russian tactics is an important precedent for the countries of the Caspian Sea region to keep in mind as they make decisions that will determine their economic and political future for decades to come. In contrast, the western strategy of promoting quality products and services, while ensuring safety and conducting business according to western ethical norms, has been less successful than western firms originally envisioned. Undoubtedly western firms have

    This the petrogenesis of the Romeu leucogranites can be satisfactorily explained by a fractionation model in which an original granite magma produced a leucogranites rest melt. The S-type characteristics of the leucogranites (high paraluminicity, high initial Sr isotope ratio and the pattern of trace element enrichment and depletion) follow from this model. Research within the Ibergranite Project show that the granite magmas derive from earlier mets, wich descendent from gabbro melts, ultimately originating in the matle. It is possible that the original magma was contaminated with crustal rocks during its residence in the lower crust, but these leucogranites are uncontaminated high level fractionates. (C.D.G.) [pt

  5. The low-enrichment fuel development program

    In the 1950s and 1960s, low-power research reactors were built around the world utilized MTR-type fuel elements containing 20% enriched uranium. However, the demand for higher specific power created a need for greater uranium-235 concentrations. Early difficulties in increasing uranium content led to the substitution of highly enriched uranium in place of the 20% enriched fuel previously utilized. The highly enriched material also yielded other benefits including longer core residence time, higher specific reactivity, and somewhat lower cost. Highly enriched material then became readily available and was used for high-power reactors as well as in low-power reactors where 20% enriched material would have sufficed. The trend toward higher and higher specific power also led to the development of the dispersion-type fuels which utilized highly enriched uranium at a concentration of about 40 wt%. In the 1970's, however, concerns were raised about the proliferation resistance of fuels and fuel cycles. As a consequence, the U.S. Department of State has recently prohibited the foreign shipment of highly enriched material, except where prior contractual obligation or special merit exists. This will impact on the availability and utilization of highly enriched uranium for research and test reactor fuel. It has also stimulated development programs on fuels with higher uranium content which would allow the use of uranium of lower enrichment. The purpose of this report is to briefly describe the overall fuel-development program which is coordinated by Argonne National Laboratory for the Department of Energy, and to indicate the current and potential uranium loadings. Other reports will address the individual fuel-development activities in greater detail

    Among all of the high-throughput detection methods, PCR-based methodologies are regarded as the most cost-efficient and feasible methodologies compared with the next-generation sequencing or ChIP-based methods. However, the PCR-based methods can only achieve multiplex detection up to 15-plex due to limitations imposed by the multiplex primer interactions. The detection throughput cannot meet the demands of high-throughput detection, such as SNP or gene expression analysis. Therefore, in our study, we have developed a new high-throughput PCR-based detection method, multiplex enrichment quantitative PCR (ME-qPCR), which is a combination of qPCR and nested PCR. The GMO content detection results in our study showed that ME-qPCR could achieve high-throughput detection up to 26-plex. Compared to the original qPCR, the Ct values of ME-qPCR were lower for the same group, which showed that ME-qPCR sensitivity is higher than the original qPCR. The absolute limit of detection for ME-qPCR could achieve levels as low as a single copy of the plant genome. Moreover, the specificity results showed that no cross-amplification occurred for irrelevant GMO events. After evaluation of all of the parameters, a practical evaluation was performed with different foods. The more stable amplification results, compared to qPCR, showed that ME-qPCR was suitable for GMO detection in foods. In conclusion, ME-qPCR achieved sensitive, high-throughput GMO detection in complex substrates, such as crops or food samples. In the future, ME-qPCR-based GMO content identification may positively impact SNP analysis or multiplex gene expression of food or agricultural samples. Graphical abstract For the first-step amplification, four primers (A, B, C, and D) have been added into the reaction volume. In this manner, four kinds of amplicons have been generated. All of these four amplicons could be regarded as the target of second-step PCR. For the second-step amplification, three parallels have been taken for

  7. POCHVENNICHESTVO IN RUSSIAN LITERATURE: THE METAPHOR AS IDEOLOGEME

    2012-11-01

    Full Text Available Original as it was, the phenomenon of pochvennichestvo (roughly translated as «native soil» in Russian thought and literature is often accompanied by a number of myths, misperceptions and erroneous commonplaces. It is not infrequent that those who never shared the ideas of pochvennichestvo are described as its adepts, and those who did, are often misquoted, with some notions, ideas and phrases misattributed to them. The ideological and literary agenda of pochvennichestvo was formed by the Vremya (1861-1863 and Epokha (1864-1865 magazines published by the brothers Dostoevsky — Fedor and Mikhail. Their outlook and vigorous action, discussions of submitted articles at board meetings, polemics with other periodicals — all of these factors contributed to the general trend of pochvennichestvo with its typical mutual influence of all its members. Fedor Dostoevsky's role on its development was decisive, as he kept consistently substantiating ideas which were new for Russian literature. Our article analyses the pochva (soil metaphor in the ideology of new school of literature and political movements which Dostoevsky helped set up in 1860s-1870s. According to him, pochva includes everything that gives birth and unites: people, homeland, native language and mother earth. They are all linked together by the mystery of Russia as the keeper of Orthodox faith and Christ as the «ideal of the people». One has to reunite with the pochva by becoming one with the people and strive to see all estates united. To be a pochvennik meant to love Russia and its people, to be a Russian and identify as one, to follow the faith of the fathers and honour the native land. In the 20th century, pochvennichestvo resolved the old argument between the Westernizers and Slavophiles. The word pochvennik was applied to the authors who stayed loyal to Russian traditional values, rural communities and traditions of Russian literature. Various authors and critics have been

    In March 2010, the U.S. National Nuclear Security Administration's Office of Global Threat Reduction (GTRI), in collaboration with the Chilean Nuclear Energy Commission (CCHEN), completed a shipment of 18.2 kilograms of non-U.S.-origin highly enriched uranium (HEU) to the United States. The HEU was in the form of 71 aluminium-clad material test reactor (MTR) fuel elements and was the first GTRI Gap Program shipment that included non-U.S. origin irradiated nuclear fuel. Although shipments of research reactor fuels are not unique, this shipment served as a cornerstone to the first Presidential Nuclear Security Summit held in Washington, D.C., in April 2010. Carrying out the shipment became critical when a severe earthquake struck Chile just one day before the shipment was to occur. As the fuel had already been packaged in casks and the ocean vessels were nearing the port, U.S. and Chilean officials decided that it was most imperative that the shipment continue as planned. After careful analysis of the situation, inspection of the transportation packages, roadways, and port services, the shipment team was able to make the shipment occur in a safe and secure manner. This paper describes the loading activities at both the RECH-1 and RECH-2 reactors as well as the transportation of the loaded casks to the port of departure. (author)

    International Nuclear Information System (INIS)

    Sagen, Eirik Lund; Tsygankova, Marina

    2008-01-01

    In this paper we use both theoretical and numerical tools to study potential effects on Russian gas exports from different Russian domestic gas prices and production capacities in 2015. We also investigate whether a fully competitive European gas market may provide incentives for Gazprom, the dominant Russian gas company, to change its export behaviour. Our main findings suggest that both increased domestic gas prices and sufficient production capacities are vital to maintain Gazprom's market share in Europe over the next decade. In fact, Russia may struggle to carry out its current long-term export commitments if domestic prices are sufficiently low. At the same time, if Russian prices approach European net-back levels, Gazprom may reduce exports in favour of a relatively more profitable domestic market

    Chaussy, L.; Boyer, R.

    1968-01-01

    Isotopic analysis of uranium in the form of the hexafluoride by mass-spectrometry gives gross results which are not very accurate. Using a linear interpolation method applied to two standards it is possible to correct for this inaccuracy as long as the isotopic concentrations are less than about 10 per cent in U-235. Above this level, the interpolations formula overestimates the results, especially if the enrichment of the analyzed samples is higher than 1.3 with respect to the standards. A formula is proposed for correcting the interpolation equation and for the extending its field of application to high values of the enrichment (≅2) and of the concentration. It is shown that by using this correction the results obtained have an accuracy which depends practically only on that of the standards, taking into account the dispersion in the measurements.

  14. Candidate processes for diluting the 235U isotope in weapons-capable highly enriched uranium

    International Nuclear Information System (INIS)

    Snider, J.D.

    1996-02-01

    The United States Department of Energy (DOE) is evaluating options for rendering its surplus inventories of highly enriched uranium (HEU) incapable of being used to produce nuclear weapons. Weapons-capable HEU was earlier produced by enriching uranium in the fissile 235 U isotope from its natural occurring 0.71 percent isotopic concentration to at least 20 percent isotopic concentration. Now, by diluting its concentration of the fissile 235 U isotope in a uranium blending process, the weapons capability of HEU can be eliminated in a manner that is reversible only through isotope enrichment, and therefore, highly resistant to proliferation. To the extent that can be economically and technically justified, the down-blended uranium product will be made suitable for use as commercial reactor fuel. Such down-blended uranium product can also be disposed of as waste if chemical or isotopic impurities preclude its use as reactor fuel

    2016-07-01

    As one of the most potential electrode materials for supercapacitors, nitrogen-enriched nanocarbons are still facing challenge of constructing developed mesoporosity for rapid mass transportation and tailoring their pore size for performance optimization and expanding their application scopes. Herein we develop a series of nitrogen-enriched mesoporous carbon (NMC) with extremely high mesoporosity and tunable mesopore size by a two-step method using silica gel as template. In our approach, mesopore size can be easily tailored from 4.7 to 35 nm by increasing the HF/TEOS volume ratio from 1/100 to 1/4. The NMC with mesopores of 6.2 nm presents the largest mesopore volume, surface area and mesopore ratio of 2.56 cm3 g-1, 1003 m2 g-1 and 97.7%, respectively. As a result, the highest specific capacitance of 325 F g-1 can be obtained at the current density of 0.1 A g-1, which can stay over 88% (286 F g-1) as the current density increases by 100 times (10 A g-1).

    Full Text Available The article is devoted to the theme of forming the war image, in particular, considering the influence of Russian social stereotypes in the second half of 19th — early 20th century. The main sources of this work were the articles and notes that were creating by the famous journalist and writer Vas. I. Nemirovich-Danchenko. As a war correspondent he participated in almost all major conflicts of the second half of 19th — early 20th century and left a significant mark in j ournalism and literature. All ofthis works were written during Russian-Turkish (1877—1878 and Russian-Japanese (1904—1905 wars. These were not only main social fears and stereotypes of Russian society about coming war and enemy, but also the stories and collective images brought in the articles to make the stereotypes stronger or to deny it. Nemirovich-Danchenko developed his own personal collection of images and techniques, which he managed to convey the most delicate nuances necessary to achieve its objectives. Formed during the Russian-Turkish war this collection of images has undergone only minor changes. It enriched the author’s reflections on the theme of evolution wars that he had seen. Analysis of materials of this article was produced in accordance with modern views of the scientific community on the problems of formation of the images of war. The aim was to show the real influence of public attitudes and views on the development of stereotypes and their expression in the press. First of all it concerns the period immediately before the war and the development of pre-existing views. The author investigated the prognostic and simultaneous steps of forming the images of war, but left beyond reasoning retrospective (final view.

    Full Text Available The goals set forth in regulatory documents for the development of Russian education presuppose quantitative evaluation of factors and conditions that ensure students’ achievement of high competence, personality development, and self-realization. Evaluation of intellectual and personality characteristics of first-year university students and study of the relationship among these characteristics thus become important tasks. The research objective was to evaluate relationships among social and abstractlogical types of intelligence, personality characteristics, and exam effectiveness (performance. The study sample was made up of 900 first-year university students (55.2% female and 44.8% male from Tomsk State University who filled in paper-and-pencil forms in Russian: The Evaluation of Choice in Conflict Situations Questionnaire, Raven’s Progressive Matrices, the Self-Organization of Activity, the Reflexivity Type Assessment Test, the Self-Determination Scale, the Satisfaction with Life Scale, and the World Assumptions Scale. Scores on the Unified National Examination in Mathematics (UNE in Mathematics and the first exam results at the university were used to measure academic performance. The data were statistically processed using descriptive analysis, correlation analysis, and factor analysis. The preference for compromising and collaborating strategies indicates a high level of social intelligence and contributes to socio-psychological adaptation of young people to conditions of university education that are new to them, which require greater independence and activity. Social intelligence and abstract-logical intelligence are relatively independent intelligence types. Social intelligence and personality characteristics are not determinants of scores on the UNE in Mathematics. Probably the process of educating students in mathematics in the graduating classes of Russian secondary schools is replaced by training to solve problems on the UNE, so

    2016-07-01

    The need to use highly enriched uranium (HEU) in civil nuclear applications is shrinking due to international efforts worldwide in the last three decades. Today low enriched uranium (LEU) that is not suitable for nuclear weapon purposes can be used instead in almost all civil applications. An overview of the current HEU use worldwide will be presented before focusing more on the use of HEU in research reactors and the conversion of existing reactors to LEU. Specifically interesting is the case of the German research reactor in Munich, the FRM-II. The reactor operates since ten years after intense national and international discussions over the use of weapon usable HEU to fuel the reactor. Since its construction the reactor is therefore obliged to convert to lower enrichment levels as soon as a suitable fuel becomes available. Despite huge international efforts to develop new fuels it is still not clear if and when the reactor can be converted.

    Full Text Available The article deals with the history and the problems of the Russian Orthodox Church in Denmark – and here seen in a Danish-Russian historical perspective, especially, in the last 300 years. The relations between the Danes and the Orthodox Church began, however, around 900 years before, in the Eastern European state of Kievan Rus. The article shows that the history of the church is closely linked to the political development in Russia. In this article, the history of the church and the changing Russian congregations will be illuminated in a historical perspective so that both the church and church buildings will throw a new light on the role of the Russian Church in both Danish and Russian history. In addition, it will be analysed to what extent trade policy, strategy and power policy and family relations have influenced the role and position of the Russian Church in Danish history.

    To examine if, and to what extent, disparities in health status exist between ethnic Russians and the native majority populations of four former Soviet Republics; and to determine to what extent indicators of socio-economic status and lifestyle behaviours explain variations in health status. Data from the World Health Organization's World Health Surveys of former Soviet Republics that include information on ethnicity (i.e. Estonia, Latvia, Ukraine, Kazakhstan and Russia) were used. Russia was included as the benchmark population as it is the country of origin of ethnic Russians. Data were collected from respondents aged ≥25 years in 2001-2003. Principal component analysis was used to derive the Health Status Index and Household Wealth Index. Multiple classification analysis was applied to examine the effects of the determinants on health status, including ethnic group membership. In Estonia and Kazakhstan, ethnic Russians have, on average, a lower health status than members of the majority population, while their health status is higher in Ukraine. Higher levels of material wealth, educational attainment and physical activity were associated with a higher health status. The association of these variables with health status was often stronger than the association between ethnic group membership and health status. Differences in health status between Russian ethnic minorities and the majority populations were found in Estonia and Kazakhstan, but were non-existent in Latvia and were the opposite of what was expected in Ukraine. Use of the Health Status Index in combination with multiple classification analysis proved to be a useful approach to examine health status differentials, and to identify and profile vulnerable groups in a society.

    Full Text Available The article discusses Power Distance as one of the cultural dimensions of Russian education based on the perceptions and views of Russian pre-service and young in-service teachers. These views were elicited in the context of a 2 ECTS master’s degree course, “Cultural Dimensions of Education,” offered at Herzen State Pedagogical University of Russia. The course includes Hofstede’s framework of cultural dimensions and the manifestation of these dimensions in educational settings, Hall’s cultural-factors theory (particularly high- and low- context cultures and monochronic versus polychronic cultures, but the research focuses on only one of the cultural dimensions, Hofstede’s Power Distance. The students’ reflections on their own experiences presented in writing as case studies and discussed with their peer students have been analyzed. Evidence has been gained that large Power Distance is a typical feature of Russian educational settings’ attitudes and relationships among all the actors—school administration, teachers, pupils, and their parents. The article discusses some of the cases presented and analyzed by the students and their arguments supporting their points of view.

    Full Text Available Historical demographic research plays an important role in multi-disciplinary projects in historical, social and political sciences at the moment. It is of great importance for migration and social policy studies and also concerns economics, material and intellectual culture and inter-ethnic and inter-faith relations. The border regions with high population mobility are of particular interest. The search in the Russian State Historical Archive uncovered a complex of primary census material concerning the Russian population in the Grand Duchy of Finland. Thus it became possible to introduce previously unstudied documents, containing data on the Russian subjects, mainly military men, stationed at Helsinki, Sveaborg, Tavastgus, Torneo and a number of other garrisons into scientific use. Russian military men in those towns comprised quite a noticeable element in the composition of the population. It is no doubt that Russian officers and their family members were part of the town elite according to their social status, life experience, and level of education. Consequently the primary documents of the 1897 census give us a unique opportunity to see the demographic situation of the Russian garrisons accommodated in the Vyborg Governorate in the end of the 19th century from the inside, and add living colors related to biographies of certain people to the dry statistical picture which describes the population of the town.

  9. Study on the meat isotopic composition for origin identification

    Full Text Available Russian consumer and governmental authorities are equally concerned to know where food products come from. This requires more accurate and specialized methods for the evaluation of geographical location. The following methods are used: chemometrics, histological and histochemical, genomic and proteomic, microbiological, immunochemical and mass spectrometric. Method of stable isotope analysis is becoming increasingly promising nowadays for the identification of meat and meat products' place of origin. The isotope ratios of the four elements - carbon, nitrogen, oxygen and hydrogen, are mainly determined. The method is successfully used to identify a country of origin of wines, juices and water. The aim of the research was to study the stable isotope ratios for pork and beef samples purchased in Moscow supermarkets (Russian Federation. The country of production of meat samples was determined according to specifications and/or labels. The geography of countries of meat samples origin includes Europe, both America continents and Australia. Databases collected by the All-Russian Scientific Research Institute of the Brewing, Non-Alcoholic and Wine Industrywere used for the analysis and interpretation of the results. Values of 13С/12С, δ13С, 18О/16О, δ18О, 2Н/1Н, δ2Н for 30 pork and beef samples from 13 countries were obtained. Differences in stable isotope ratios were found depending on place of origin. The data correlated with the oxygen isotope characteristics for wine, which were in the range from 2.5 to 4.5 ppm. According to the 13С/12С, δ13С results, the assumption was made about a false indication of the region for the beef sample. Despite the fact that beef was labeled as a product of Lithuania, the region of origin was most probably defined as Germany. The studies carried out showed the possibility to identify the region of raw meat origin by the stable isotope ratio.

    The issues of constructing high-rise, primarily residential, buildings have a great social significance. Not every plot of land, acquired in the Russian Federation is suitable for high-rise construction. Therefore, every construction company that plans to erect a multi-apartment building, a high-rise office building, or a skyscraper must take into account not only technical norms but as well sanitary legislation regulations that set obligatory requirements about insolation of apartments. The article includes a short study of several norms in the Russian legislation regarding insolation of dwellings; analises the problems of judicial interpretation of the statutory limitations. In this aspect it researches the debatable questions arising in practice of state arbitration courts dealing with the lawsuits on allocation of land-plots by the local administration. The analysis of the judicial practice is followed by description of the difficulties facing the developers of land-plots, concerning the project and territorial planning documentation.

    Recent studies indicate that eutectic high-entropy alloys can simultaneously possess high strength and high ductility, which have potential applications in industrial fields. Nevertheless, microstructural origins of the excellent strength–ductility combination remain unclear. In this study, an AlCoCrFeNi 2.1 eutectic high-entropy alloy was prepared with face-centered cubic (FCC)(L1 2 )/body-centered-cubic (BCC)(B2) modulated lamellar structures and a remarkable combination of ultimate tensile strength (1351 MPa) and ductility (15.4%) using the classical casting technique. Post-deformation transmission electron microscopy revealed that the FCC(L1 2 ) phase was deformed in a matter of planar dislocation slip, with a slip system of {111} <110>, and stacking faults due to low stacking fault energy. Due to extreme solute drag, high densities of dislocations are distributed homogeneously at {111} slip plane. In the BCC(B2) phase, some dislocations exist on two {110} slip bands. The atom probe tomography analysis revealed a high density of Cr-enriched nano-precipitates, which strengthened the BCC(B2) phase by Orowan mechanisms. Fracture surface observation revealed a ductile fracture in the FCC(L1 2 ) phase and a brittle-like fracture in the BCC(B2) lamella. The underlying mechanism for the high strength and high ductility of AlCoCrFeNi 2.1 eutectic high-entropy alloy was finally analyzed based on the coupling between the ductile FCC(L1 2 ) and brittle BCC(B2) phases.

    The departure of Mikhail Khodorkovsky has brought an end to the idyllic times of supplies of Russian oil to the MOL-Slovnaft group. The group used to purchase oil directly from Yukos. But now brokers have again entered the Central European oil business. And their aim is to take control over all of the oil business. The Russians demonstrated the changed situation to Slovakia last autumn: you will either accept the new model, or there will be problems with oil deliveries. Consumers got the message. The main brokers of Russian oil in Central Europe are the Swiss companies Glencore and Fisotra. Little information is available regarding these commodity brokers. But the information available is sufficient to indicate that these are not small companies. Glencore undertakes 3% of all international oil trades. With an annual turnover of 72 billions USD, it was the biggest Swiss company by turnover in 2004. Fisotra also has an extensive product portfolio. It offers financial and commercial services and does not hide its good relations with Russian oil companies. Between 1994 and 1998, it managed their financial operations with major western companies such as BP, Cargill, Elf, Exxon, Shell, Total, and Mutsubishi and also with Glencore. Fisotra states that some of its clients achieved an annual turnover of 1.5 billions USD. At present, the Swiss brokers receive a fee of 1 to 1.5 USD per barrel. The Russian political elite must be aware of these brokerage services as the oil transport through the transit system is closely monitored by the state owned company Transneft. (authors)

    The collected water chemistry and radiochemistry data during the operation of the Kozloduy NPP Unit 5 for the period 2006-2009 (12-th, 13-th 14-th and 15-th fuel cycles) undoubtedly indicate for WWER-1000 Units (whose specific features are: Steam generators with austenitic stainless steel 08Cr18N10T tubing; Steam generators are with horizontal straight tubing and Fuel elements cladding material is Zr-1%Nb (Zr1Nb) alloy), that one realistic way for problemless implementation of 235 U high enriched fuel have been found. The main feature characteristics of this way are: Implementation of solid neutron burnable absorbers together with the dissolved in coolant neutron absorber - natural boric acid; Application of fuel cladding materials with enough corrosion resistance by the specific fuel cladding environment created by presence of SNB; Keeping of suitable coolant water chemistry which ensures low corrosion rates of core- and out-of-core- materials and limits in core (cladding) depositions and restricts out-of-core radioactivity buildup. The realization of this way in WWER-1000 Units in Kozloduy NPP was practically carried out through: 1) Implementation of Russian fuel assemblies TVSA which have as fuel cladding material E-110 alloy (Zr1Nb) with enough high corrosion resistance by presence of sub-cooled nucleate boiling (SNB) and use burnable absorber (Gd) integrated in the uranium-gadolinium (U-Gd 2 O 3 ) fuel (fuel rod with 5.0% Gd 2 O 3 ); 2) Development and implementation of water chemistry primary circuit guidelines, which require the relation between boric acid concentration and total alkalising agent concentrations to ensure coolant pH 300 = 7.0 - 7.2 values during the whole operation period. The above mentioned conditions by the passing of WWER-1000 Units in NPP Kozloduy to uranium fuel with 4.4% 235 U (TVSA fuel assemblies) practically ensured avoidance of the creation of the necessary conditions for AOA onset.

This covers a broad range of problems of country, regional and global scale, put forward and voiced conflicting estimates and judgments. Abroad, actively promoted the interpretation of the “return” of Russia to the continent as a new direction of neo-imperial ambitions of the new Russia and its aspirations to weaken the position of the West, “golden” its image in the developing countries, in the eyes of Africans. Author analyzes the impact of the emerging political, economic and social realities of the XXI century on the development prospects of the African continent in general, and on the Russian-African relations in particular. The author concludes that the increase in the weight and role of the continent in world politics and economy today requires a rethinking of the Russian approaches to the problems of scale Russian-African partnership and the formation of its long-term vision, building on the existing political, diplomatic and investment and the country's financial resources. The new dynamics of Russian-African relations is connected, first of all, with the development of partnerships in those areas where Russia has competitive potential, production capacities, high competence and experience. Including the development of natural resources, nuclear power and hydropower, military-technical cooperation, the establishment of satellite information and communication systems, cooperation in the sphere of education, health, the fight against epidemics, natural catastrophes. Russia is confident enough to overcome the deep recession of relations with Africa, recorded in the late 80's and 90-ies of XX century. However, it would be premature to claim that full-blooded “return” of Russia to the continent has already taken place. Scaling up comprehensive cooperation will depend, first, on the

  3. Combining target enrichment with barcode multiplexing for high throughput SNP discovery

    Directory of Open Access Journals (Sweden)

    Lunke Sebastian

    2010-11-01

    Full Text Available Abstract Background The primary goal of genetic linkage analysis is to identify genes affecting a phenotypic trait. After localisation of the linkage region, efficient genetic dissection of the disease linked loci requires that functional variants are identified across the loci. These functional variations are difficult to detect due to extent of genetic diversity and, to date, incomplete cataloguing of the large number of variants present both within and between populations. Massively parallel sequencing platforms offer unprecedented capacity for variant discovery, however the number of samples analysed are still limited by cost per sample. Some progress has been made in reducing the cost of resequencing using either multiplexing methodologies or through the utilisation of targeted enrichment technologies which provide the ability to resequence genomic areas of interest rather that full genome sequencing. Results We developed a method that combines current multiplexing methodologies with a solution-based target enrichment method to further reduce the cost of resequencing where region-specific sequencing is required. Our multiplex/enrichment strategy produced high quality data with nominal reduction of sequencing depth. We undertook a genotyping study and were successful in the discovery of novel SNP alleles in all samples at uniplex, duplex and pentaplex levels. Conclusion Our work describes the successful combination of a targeted enrichment method and index barcode multiplexing to reduce costs, time and labour associated with processing large sample sets. Furthermore, we have shown that the sequencing depth obtained is adequate for credible SNP genotyping analysis at uniplex, duplex and pentaplex levels.

I shall therefore avoid as much as possible duplications with these other lectures, and rather dwell on: some theoretical aspects of enrichment in general, underlying the differences between statistical and selective processes, a review and comparison between enrichment processes, remarks of general order regarding applications, the proliferation potential of enrichment. It is noteworthy that enrichment: may occur twice in the LWR fuel cycle: first by enriching natural uranium, second by reenriching uranium recovered from reprocessing, must meet LWR requirements, and in particular higher assays required by high burn up fuel elements, bears on the structure of the entire front part of the fuel cycle, namely in the conversion/reconversion steps only involving UF 6 for the moment.

    Full Text Available The article analyzes the anti-Russian historical narrative focused on the 1917 events. The relevance of the theme is determined bythe wide-ranging discussion on the Russian revolution due toits anniversary. The authors solve the problem of the scientific criticism of the anti-Russian myths, focused on the assessments and interpretations of the two Russian revolutions of 1917. In the article there are shown the ideological basis and political context of the coverage of the events of 1917. The authors analyze 5 historical ideologemes, which are disseminated in the public consciousness. They also show the cognitive and political implications of adopting the respective ideology. As a typical liberal myth, the authors regard the interpretation of the October Revolution as “stolen freedom” provided by the February revolution. In the article there is shown that through the myth of “stolen freedom” the whole history of Russia is presented as a reproduction of the “totalitarian regime”. The authors prove the incorrectness of showing Bolsheviks as the initiators of the use of mass terror tactics, to which all major opposing forces resorted. There is considered the connection of the interpretation of the Revolution as the manifestation of the “Russian rebellion” with the Russophobic myth of the Russian barbarism. The authors criticize the idea of the Bolshevik imperialism, which is allegedly based on the ideology of world revolution. The article gives the deconstruction of the myth of the Bolshevik regime illegitimacy and shows the cognitive contradictions of the attempts to counter the concepts of “October Revolution” and “October Coup”. The authors reveal that the thesis of the Constituent Assembly, as an illustration of the Bolshevik illegitimacy, doesn’t correspondent to the historical facts. The authors conclude that the issues of covering the events of both the Revolutionand the Great Patriotic War are linked to the national

    The basic RNA secondary structure prediction problem or single sequence folding problem (SSF) was solved 35 years ago by a now well-known [Formula: see text]-time dynamic programming method. Recently three methodologies-Valiant, Four-Russians, and Sparsification-have been applied to speedup RNA secondary structure prediction. The sparsification method exploits two properties of the input: the number of subsequence Z with the endpoints belonging to the optimal folding set and the maximum number base-pairs L. These sparsity properties satisfy [Formula: see text] and [Formula: see text], and the method reduces the algorithmic running time to O(LZ). While the Four-Russians method utilizes tabling partial results. In this paper, we explore three different algorithmic speedups. We first expand the reformulate the single sequence folding Four-Russians [Formula: see text]-time algorithm, to utilize an on-demand lookup table. Second, we create a framework that combines the fastest Sparsification and new fastest on-demand Four-Russians methods. This combined method has worst-case running time of [Formula: see text], where [Formula: see text] and [Formula: see text]. Third we update the Four-Russians formulation to achieve an on-demand [Formula: see text]-time parallel algorithm. This then leads to an asymptotic speedup of [Formula: see text] where [Formula: see text] and [Formula: see text] the number of subsequence with the endpoint j belonging to the optimal folding set. The on-demand formulation not only removes all extraneous computation and allows us to incorporate more realistic scoring schemes, but leads us to take advantage of the sparsity properties. Through asymptotic analysis and empirical testing on the base-pair maximization variant and a more biologically informative scoring scheme, we show that this Sparse Four-Russians framework is able to achieve a speedup on every problem instance, that is asymptotically never worse, and empirically better than achieved by

    2016-01-01

    Full Text Available This article is about establishing a common transition altitude over all territory of Russian Federation. The main objective is to prove the necessity of a common transition altitude in Russian airspace and to define, which variant of tran- sition altitude (low, medium, high is the most suitable to be implemented in Russia. ICAO and IFALPA points of view, data and experience from different states and regions all over the world were examined in order to show all the advantages and disadvantages of different approaches towards common transition altitude. The research showed that the most appro- priate common transition altitude in Russia will be 10000 feet (3050 meters, it will cover almost all the international aero- dromes and regions in the country. Only several exceptions are needed in mountainous areas. This article can be used to further study of the possibility of implementation of common transition altitude, because it can’t take into consideration all the local features of all the FIRs (Flight Information Regions in Russia. The conclusion is establishing a common transi- tion altitude over such a big part of the world as Russian Federation will lead to improvement of the flight safety, harmoni- zation with ICAO and IFALPA policies and flexibility in airspace design.

    Recent social changes in Russia have opened up many opportunities for business collaboration. To build on this, in 1992 British Nuclear Fuels Limited (BNFL) concluded and signed an agreement with the Russian ministry MINATOM to collaborate on a wide range of topics relevant to the international nuclear industry. These covered the such subjects as developing national regulatory frameworks, sharing operational experiences and practices, and establishing collaborative R and D programmes. One outcome of the agreement with MINATOM has been the setting up of a number of collaborative R and D projects with the V.G. Kholpin Radium Institute in St. Petersburg. This paper presents the results from one of these joint programmes, and describes the mutual benefits that can be obtained from such collaborative work. (authors)

    Three toluene-degrading microbial consortia were enriched under sulphate-reducing conditions from different zones of a benzene, toluene, ethylbenzene and xylenes (BTEX) plume of two connected contaminated aquifers. Two cultures were obtained from a weakly contaminated zone of the lower aquifer, while one culture originated from the highly contaminated upper aquifer. We hypothesised that the different habitat characteristics are reflected by distinct degrader populations. Degradation of toluene with concomitant production of sulphide was demonstrated in laboratory microcosms and the enrichment cultures were phylogenetically characterised. The benzylsuccinate synthase alpha-subunit (bssA) marker gene, encoding the enzyme initiating anaerobic toluene degradation, was targeted to characterise the catabolic diversity within the enrichment cultures. It was shown that the hydrogeochemical parameters in the different zones of the plume determined the microbial composition of the enrichment cultures. Both enrichment cultures from the weakly contaminated zone were of a very similar composition, dominated by Deltaproteobacteria with the Desulfobulbaceae (a Desulfopila-related phylotype) as key players. Two different bssA sequence types were found, which were both affiliated to genes from sulphate-reducing Deltaproteobacteria. In contrast, the enrichment culture from the highly contaminated zone was dominated by Clostridia with a Desulfosporosinus-related phylotype as presumed key player. A distinct bssA sequence type with high similarity to other recently detected sequences from clostridial toluene degraders was dominant in this culture. This work contributes to our understanding of the niche partitioning between degrader populations in distinct compartments of BTEX-contaminated aquifers.

    Oral health literacy has become a popular research area in the last decade; however, to date no health literacy instruments in the Russian language exist. The objectives of this study were to develop a Russian version of the Oral Health Literacy Instrument (OHLI) and to examine its reliability and validity. A convenience sample of patients who visited the dental division of the district hospital in Belarus was used in the study. The OHLI, created originally in English, was modified to adapt it to characteristics of routine dental services in Belarus and then translated into Russian, followed by back-translation. Participants completed a self-administered socio-demographic questionnaire, an oral health knowledge test and the Russian version of the OHLI (R-OHLI). Bivariate and multivariate statistical analyses, including multiple regression modeling, were performed to examine reliability and validity of the R-OHLI. Participants were 281 adult patients aged from 18 to 60 years, with a mean age of 33.1 ± 12.2; 64.1% of them were women. Cronbach's alpha values for the two sections (reading comprehension and numeracy) and the total R-OHLI were 0.853, 0.815 and 0.895, respectively. The mean total R-OHLI score was 77.2 ± 14.5; the mean reading comprehension and numeracy scores were 39.5 ± 7.5 and 37.8 ± 8.8, respectively. The R-OHLI was significantly correlated to the oral health knowledge test. Pearson's correlation coefficients between the oral health knowledge test and the reading comprehension, numeracy and total R-OHLI were 0.401, 0.258, and 0.363, respectively (p literacy instrument for Russian-speaking people.

    Full Text Available The article considers the main principles of Russian philosophy of history. The most discussed historiosophical idea, going through a variety of transformations, remains Slavyanofil doctrine of special destiny of Russia, its spiritual integrity. The author focuses on the fact that preserving «national archetype» as a key issue, Russian historiosophy offered various options related to the West as a symbol of a different worldview. Mindful of the global fascination with Buddhist understanding of human destiny and history of the world, it must be said that the Russian historiosophy presumed itself in opposition to the Buddhist concept of the historiosophical. Briefly it is explained the reasons for the occurrence of classical Russian literature historiosophical space. 1. The national literature was perceived by Russian thinkers as the «second history». 2. Figures of historical discourse were five Russian classics: Pushkin, Lermontov, Gogol, Dostoevsky, Tolstoy. 3. The fate and the works of Russian writers of the inherent rationale of national historical path in its different variants. 4. The Russian philosophy of history, to show interest in religious issues, examines the life and work of every writer as a definite spiritual model of public importance and is being implemented in the historical world. It is commented on historico-philosophical concept of Leontiev and Fedorov, Rozanov and Solovyov who emphasize that eschatology is the semantic core of Russian philosophy of history.

    2017-03-01

    Full Text Available This article aims to analyze the psychometric properties of the Russian version of the Utrecht Work Engagement Scale (UWES-9 by using a sample of 1783 employees of a large Russian organization. We conducted a series of Confirmatory Factor Analysis (CFA tests of the factorial structure and the configural, metric, scalar, factor variance, factor covariance, and factor means invariances of the model across gender and age groups. The validity of the Russian version of the UWES-9 was investigated by study- ing its relationship with burnout, job satisfaction, life satisfaction, and turnover inten- tion. The CFA showed that both the 1-factor and the 3-factor models of the UWES-9 fit well with the data, but the 3-factor model demonstrates a significantly better fit. however, the differences are minor; therefore, in practical terms, the models are iden- tical. Thus the Russian version of the UWES-9 can be used both as a three-scale mea- surement and as a single scale of work engagement. Results from the multi-group CFA provided evidence of factorial invariance of the 3-factor model across gender and age groups. Internal consistencies of the vigor, dedication, and absorption subscales are acceptable. The results also suggested the convergent, discriminant, and incremental validity of the UWES-9, as shown by its relationship with burnout, job satisfaction, life satisfaction, and turnover intention. The article also discusses the differences in levels of work engagement within different gender and age groups. Overall, the results show that the Russian version of the UWES-9 demonstrates acceptable psychometric properties comparable with the original version and those in other languages. The Russian version of the UWES-9 can therefore be recommended for use in research and practice.

  1. Genuine federalism in the Russian health care system: changing roles of government.

    Science.gov (United States)

    Chernichovsky, D; Potapchik, E

    1999-02-01

    The reforms that have affected the Russian health care system since the breakup of the Soviet Union, principally those in the general administration of the Russian Federation, have suffered from inconsistency and the absence of a strategy. The various reforms have caused a shift from a national health system characterized by highly centralized management and control, typical of the totalitarian uniform state, to a highly decentralized but fragmented multitude of state systems. Each of these systems is relatively centralized at the local level and run by local administrations with limited government infrastructure and experience. The role of government in the emerging system, and in particular the role of the federal government, remains ill defined. As a result, there is a grave risk that the Russian health care system may disintegrate as a national system. This undermines (a) the prevailing universal and fairly equitable access to care, (b) stabilization of the system following a long period of transition, and (c) the long-term reform that is required to bring the Russian health care system up to par with the health care systems in other developed countries. A rapid transition to a genuine federal health system with well-articulated roles for different levels of government, in tandem with implementation of the 1993 Compulsory Health Insurance System, is essential for the stabilization and reform of the Russian health care system.

    2004-01-01

    This paper presents a high-throughput method for the simultaneous determination of deuterium and oxygen-18 (18O) enrichment of water samples isolated from blood. This analytical method enables rapid and simple determination of these enrichments of microgram quantities of water. Water is converted into hydrogen and carbon monoxide gases by the use of a high-temperature conversion elemental analyzer (TC-EA), that are then transferred on-line into the isotope ratio mass spectrometer. Accuracy determined with the standard light Antartic precipitation (SLAP) and Greenland ice sheet precipitation (GISP) is reliable for deuterium and 18O enrichments. The range of linearity is from 0 up to 0.09 atom percent excess (APE, i.e. -78 up to 5725 delta per mil (dpm)) for deuterium enrichment and from 0 up to 0.17 APE (-11 up to 890 dpm) for 18O enrichment. Memory effects do exist but can be avoided by analyzing the biological samples in quintuplet. This method allows the determination of 1440 samples per week, i.e. 288 biological samples per week.

    Full Text Available The features and current trends in the development of the banking system of the Russian Federation are highlighted in the article. The authors propose an original method of evaluation of activities of credit organizations with the use of statistical data and rating agencies. The concept of the banking system is summarized in this article. Also its structure is analyzed by the number of credit institutions and the quality of their operations. The authors identifie differences between the concepts of banking service, banking operation and banking product and propose classification according to different characteristics of banking institutions and operations that they carry out. Then the authors go to estimating the volume of banking services in Russia and their patterns in total. Separately the main passive (deposits and loans and active operations (lending to legal entities and individuals are characterized. The authors identifie the major developments in the banking system of the Russian Federation in 2014 due to political and economic sanctions by the U.S. and Eurozone countries. The article provides a vision of the authors on the further development of the banking activity in Russia and proposes specific measures to adapt the banking system of the Russian Federation in a constantly changing political and economic conditions (financial sanctions, a change of key Central Bank rates, devaluation, etc.. According to the authors' opinion the expected prospects of development of the banking system of the Russian Federation to 2015 are: the growth in savings accounts in banks; sanctions will be of a personal nature and will not affect the largest credit institutions; the active growth of the corporate loan portfolio will continue; the growth of retail lending portfolio will continue to slow; mortgage lending will increase in the total loan portfolio of the banking sector of Russia.

  6. Cultural Identity in Everyday Interactions at Work: Highly Skilled Female Russian Professionals in Finland

    Directory of Open Access Journals (Sweden)

    Malgorzata Lahti

    2013-12-01

    Full Text Available The dominant research strands into social interaction in culturally diverse workplaces have focused on issues of organizational efficiency and discrimination, and they have treated cultural identity as static, monolithic, and universally shared. This study aims to problematize this view. It is argued that our understanding of cultural workplace diversity could be extended through the integration of interpretive and critical interpersonal communication theorizing on cultural identity as dynamic and processual, constructed between and among people in everyday workplace interactions and in relation to larger social, political, and historical forces. This argument is illustrated by an analysis of in-depth interviews with 10 female Russian immigrants in Finland who performed interactionintense knowledge work. The women talked about their everyday workplace interactions and how they thought Russian identity mattered in them. These data were analyzed with the inductive method of interpretive description designed to provide a systematic description of the phenomenon delineating its characteristic themes and accounting for individual variations within it. The analysis led to the identification of four communication sites for distinct formations of Russian identity: expressing professionalism, managing initial encounters, facing stigma, and facilitating intercultural learning. The findings offer novel insights into social interaction in culturally diverse workplaces with implications for both employee well-being and organizational processes.

  7. Gazprom vs. other Russian gas producers: The evolution of the Russian gas sector

    Lunden, Lars Petter; Fjaertoft, Daniel; Overland, Indra; Prachakova, Alesia

    2013-01-01

    The non-Gazprom gas producers (NGPs) doubled their share of the Russian domestic gas market between 2000 and 2010 and have continued growing since then. For several years especially Novatek expanded. More recently, Rosneft has emerged as a key player, not least through its purchase of TNK-BP. This article begins with an overview of the companies in the Russian gas sector, their resource bases and capacities, and subsequently examines whether differences in field development costs and export market access may make it rational for Gazprom to continue ceding market share to the NGPs. With rising costs of Gazprom's queue of greenfield developments, any delays in Gazprom's investment program may be compensated through increased NGP production. The article argues that the NGPs are ready to fill the gap, may be allowed to do so and are already increasing their market share in an increasingly competitive market. The stage may now be set for a continued gradual transformation of the Russian gas market, in which the interests of Gazprom and the NGPs may be complementary or may be pitted against each other, but those of the Russian Federation are in any case likely to be better fulfilled than in the past. - Highlights: • Other Russian gas producers, especially Novatek and Rosneft, are taking market shares from Gazprom. • Gazprom has a monopoly on exports and has had a de facto monopoly on the domestic pipeline grid through its control over trunk pipelines. • Gazprom's greenfield projects are more expensive than those of other producers. • Gazprom's loss of market shares to other producers in the domestic market may actually be in Gazprom's interest

  8. Metal enrichment in the Fermi bubbles as a probe of their origin

    The Fermi bubbles are gigantic gamma-ray structures in our Galaxy. The physical origin of the bubbles is still under debate. The leading scenarios can be divided into two categories. One is nuclear star-forming activity similar to extragalactic starburst galaxies and the other is past active galactic nucleus (AGN)-like activity of the Galactic center supermassive black hole. In this letter, we propose that metal abundance measurements will provide an important clue to probe their origin. Based on a simple spherically symmetric bubble model, we find that the generated metallicity and abundance patterns of the bubbles' gas strongly depend on assumed star formation or AGN activities. Star formation scenarios predict higher metallicities and abundance ratios of [O/Fe] and [Ne/Fe] than AGN scenarios do because of supernovae ejecta. Furthermore, the resultant abundance depends on the gamma-ray emission process because different mass injection histories are required for the different gamma-ray emission processes due to the acceleration and cooling time scales of non-thermal particles. Future X-ray missions such as ASTRO-H and Athena will give a clue to probe the origin of the bubbles through abundance measurements with their high energy resolution instruments.

    Historical roots and further development of bioethics in domestic neurology and epileptology are considered. The main bioethical principles were established during the formation of the Russian clinical school and neurosciences. It is most distinctly seen in the development of bioethics in neurology and epileptology. In the author's opinion, the Russian scientist V.M. Bekhterev had played a prominent role in the field. In the time when the term "bioethics" was not coined and its principles were not formulated, V.M. Bekhterev had created the Russian league against epilepsy and established the foundations of the International League Against Epilepsy (ILAE) as the organizations working on the problems of medical and social care to patients with epilepsy. In Russia, the Russian society of neurologists has been doing a great work in the field.

    Full Text Available Circulating tumor cells (CTCs are cancer cells that can be isolated via liquid biopsy from blood and can be phenotypically and genetically characterized to provide critical information for guiding cancer treatment. Current analysis of CTCs is hindered by the throughput, selectivity and specificity of devices or assays used in CTC detection and isolation.Here, we enriched and characterized putative CTCs from blood samples of patients with both advanced stage metastatic breast and lung cancers using a novel multiplexed spiral microfluidic chip. This system detected putative CTCs under high sensitivity (100%, n = 56 (Breast cancer samples: 12-1275 CTCs/ml; Lung cancer samples: 10-1535 CTCs/ml rapidly from clinically relevant blood volumes (7.5 ml under 5 min. Blood samples were completely separated into plasma, CTCs and PBMCs components and each fraction were characterized with immunophenotyping (Pan-cytokeratin/CD45, CD44/CD24, EpCAM, fluorescence in-situ hybridization (FISH (EML4-ALK or targeted somatic mutation analysis. We used an ultra-sensitive mass spectrometry based system to highlight the presence of an EGFR-activating mutation in both isolated CTCs and plasma cell-free DNA (cf-DNA, and demonstrate concordance with the original tumor-biopsy samples.We have clinically validated our multiplexed microfluidic chip for the ultra high-throughput, low-cost and label-free enrichment of CTCs.

  18. TRIGA low enrichment fuel

    International Nuclear Information System (INIS)

    Gietzen, A.

    1993-01-01

    Sixty TRIGA reactors have been sold and the earliest of these are now passing twenty years of operation. All of these reactors use the uranium zirconium hydride fuel (UZrH) which provides certain unique advantages arising out of its large prompt negative temperature coefficient, very low fission product release, and high temperature capability. Eleven of these Sixty reactors are conversions from plate fuel to TRIGA fuel which were made as a result of these advantages. With only a few exceptions, TRIGA reactors have always used low-enriched uranium (LEU) fuel with an enrichment of 19.9%. The exceptions have either been converted from the standard low-enriched fuel to the 70% enriched FLIP fuel in order to achieve extended lifetime, or are higher powered reactors which were designed for long life using 93%-enriched uranium during the time when the use and export of highly enriched uranium (HEU) was not restricted. The advent of international policies focusing attention on nonproliferation and safeguards made the HEU fuels obsolete. General Atomic immediately undertook a development effort (nearly two years ago) in order to be in a position to comply with these policies for all future export sales and also to provide a low-enriched alternative to fully enriched plate-type fuels. This important work was subsequently partially supported by the U.S. Department of Energy. The laboratory and production tests have shown that higher uranium densities can be achieved to compensate for reducing the enrichment to 20%, and that the fuels maintain the characteristics of the very thoroughly proven standard TRIGA fuels. In May of 1978, General Atomic announced that these fuels were available for TRIGA reactors and for plate-type reactors with power levels up to 15 MW with General Atomic's standard commercial warranty

  1. Russian electricity reform. Emerging challenges and opportunities

    Energy Technology Data Exchange (ETDEWEB)

    NONE

    2005-07-01

    The Russian Government is pursuing a strategy of very high economic growth, with the objective of doubling gross domestic product in ten years. It recognises the central role the electricity sector has to play to achieve this target and has embarked on a highly ambitious program of electricity reform. If it is to succeed, the reform program will have to create market structures, market rules and a regulatory framework that will foster competitive wholesale and retail electricity markets. At the same time, it will have to deal with sensitive social issues related to tariff rebalancing and the removal of cross subsidies. Only competitive markets based on transparent prices that reflect costs can deliver the efficient, reliable and internationally competitive performance needed to meet the government's economic targets. Such markets are essential to attract new investment that will be required to ensure security of electricity supply after 2010. This book focuses on key aspects of the proposed reform that could have an important bearing on its success. It also raises concerns as to the pace of reform in related areas, such as the need for complementary reforms in the Russian natural gas sector. The IEA commends the Russian Government on its efforts to embrace this electricity reform - a key element critical to meeting the challenges ahead in terms of its economic growth and energy security. 17 figs., 10 tabs., 3 maps.

  2. Winnowing DNA for rare sequences: highly specific sequence and methylation based enrichment.

    Full Text Available Rare mutations in cell populations are known to be hallmarks of many diseases and cancers. Similarly, differential DNA methylation patterns arise in rare cell populations with diagnostic potential such as fetal cells circulating in maternal blood. Unfortunately, the frequency of alleles with diagnostic potential, relative to wild-type background sequence, is often well below the frequency of errors in currently available methods for sequence analysis, including very high throughput DNA sequencing. We demonstrate a DNA preparation and purification method that through non-linear electrophoretic separation in media containing oligonucleotide probes, achieves 10,000 fold enrichment of target DNA with single nucleotide specificity, and 100 fold enrichment of unmodified methylated DNA differing from the background by the methylation of a single cytosine residue.

    Agreements between the governments of the US and the Russian Federation for the US purchase of low enriched uranium (LEU) derived from highly enriched uranium (HEU) from dismantled Russian nuclear weapons calls for the establishment of transparency measures to provide confidence that nuclear nonproliferation goals are being met. To meet these transparency goals, the agreements call for the installation of nonintrusive US instruments to monitor the down blending of HEU to LEU. The Blend Down Monitoring System (BDMS) has been jointly developed by the Los Alamos National Laboratory (LANL) and the Oak Ridge National Laboratory (ORNL) to continuously monitor 235 U enrichments and mass flow rates at Russian blending facilities. Prior to its installation in Russian facilities, the BDMS was installed and operated in a UF 6 flow loop in the Paducah Gaseous Diffusion Plant simulating flow and enrichment conditions expected in a typical down-blending facility. A Russian delegation to the US witnessed the equipment demonstration in June, 1998. To conduct the demonstration in the Paducah Gaseous Diffusion Plant (PGDP), the BDMS was required to meet stringent Nuclear Regulatory Commission licensing, safety and operational requirements. The Paducah demonstration was an important milestone in achieving the operational certification for the BDMS use in Russian facilities

  6. Term Croatian considered in russian context

    Full Text Available Term Croatian is considered in Russian context, i. e. context of Russian scientific material (which is comparable to the unwritten situation in universities. Russian scientific texts connect term Croatian, almost without an exception, with the term Serbian in words such as Serbo-Croatian. This point of view is politically approved in the period untill 1990’s, but it exists in the 21st century’s scientific material. The nature of the problem lays, at the same time, in politics, language and society; thus, the question is: what is the reason of such a context in which Croatian language is placed now? There are no arguments for it, especially if it is for Slovak language politically based and language approved to be an entity – in comparison to the Czech language; for Ukrainian (once Littlerussian – at least in principle, in comparison to the Russian, or, more convincable, Belorussian to Russian (the standard Belorussian language exists from 1905. The term Croatian is independently, even in new books, connected with terms of soil, state, nation, but not language. And though today, because of political reasons, exists an awareness of Croatian language without its Serbian mirror reflexion, the term Serbo-Croatian stays. Thus, this paper looks through the history concerning Croatian language in 19, 20 and 21st century’s Russian philology, including Juraj Križanić and Vatroslav Jagić – innovators of the Croatian word in Russia.

    Full Text Available The aim of our research is to study the endemics of the xerophilous flora of the Russian Caucasus in connection with the matter of knowing the genesis.Methods. The study is based on the field research expeditions.Findings. The presence of endemic species in flora is an indicator of its originality, and the degree of originality is determined by the extent of the endemic species. In general, according to our geographic analysis, the number of endemic species in xerophilous flora of the Russian Caucasus accounts for 32% (326 species, of which 25% of all endemic species have natural habitats within entire Caucasus, 66% are widespread in the Greater Caucasus, and 9% in the Pre-Caucasian region.Conclusion. Endemic species of xerophytes of the flora, in their overwhelming majority, are euxerophytes, and most steno-endemics also belong to this group of xerophytes. In a systematic aspect, the leading family, containing the largest number of endemic species, is Asteraceae (in percentage terms - Lamiaceae and Jurinea is a leading genus (in percentage terms - Psephellus. In relation to the substrate, calcixerophytes are the dominants and most saturated endemics in quantitative terms are the belt of mountain xerophytes. The predominant biomes are hemicryptophytes; as compared with the number of biomorphes, among chamaephytes there is the biggest quantity of endemics. 

  8. Russian oil workers seek employment abroad

    1992-01-01

    This paper reports that American oil workers discouraged by bleak employment opportunities in the U.S. petroleum industry face increasing competition abroad from Russians seeking a living wage. Moscow's Zagrantrud (Foreign Labor) firm believes millions of Russian skilled and unskilled workers in many occupations will try to find jobs in other countries. The Russian enterprise says it is selecting a group of construction workers to build a refinery in Columbia. Kuwait also wants Russian construction personnel. Russia is especially eager to find overseas work for petroleum industry workers who have lost their jobs in Viet Nam and Cuba. The number of specialists from the former U.S.S.R. in Cuba, many of them engaged in oil exploration and production or pipeline and refinery construction, has fallen from several thousand 2 years ago to 250 at present as Moscow's relations with Havana cooled

  9. The philosophical implications of Russian conceptualism

    Directory of Open Access Journals (Sweden)

    Mikhail Epstein

    2010-01-01

    Conceptualism identifies itself as a predominantly Russian-Soviet mode of thinking. In the West, the correlation between ideological signs and observable reality has been persistently validated through scientific and economic practice; while in Russia, traditionally, reality itself has been constructed from ideological signs generated by its ruling minds as a kind of hyper-reality. Thus, Russian Conceptualism sees itself not as a mere replica of Western postmodernism, but as a reflection of the underlying structures of Russian history, where the signs of reality have always been subject to ideological manipulation.

    2012-01-01

    Internationalizing psychology is an important component of current globalization trends. American textbooks on the history of psychology and introductory psychology were surveyed for the presence of historical and contemporary important Russian psychologists to assess the current status of Russian-American crossfertilization. Of a list of 97 important Russian psychologists, as determined by the editors of the Russian journal Methodology and History in Psychology, less than 22% are mentioned in the reviewed texts. The most common names were Pavlov, Luria, and Vygotsky. As the internet is arguably the single most important factor affecting the increase of international communication and dissemination of knowledge, we also searched for these 97 names on various websites, most notably Wikipedia and Google. Forty-one internet sites contained some amount of biographical information about Russian psychologists. On Wikipedia, 14 Russian psychologists had articles documenting biographical information. We also developed a rubric to determine the amount of information available on the internet for these psychologists and compared Wikipedia's mean score with various other websites. Wikipedia pages on average had a significantly higher score than the rest of the internet. Recommendations to improve Russian coverage in America are provided and include: (1) developing pages on Wikipedia and other virtual venues highlighting Russian contributions, (2) soliciting articles for US journals from Russian psychologists, and (3) incorporating Russian contributions in introductory and historical textbooks. We provide a partial bibliography of Russian contributions that can be used by authors of such textbooks. We would like to thank Dr Viktor Fedorovich Petrenko and Dr Igor Nikolaevich Karitsky from the journal Methodology and History of Psychology for supplying the names of the Russian psychologists. We would also like to express our appreciation to Robert García for reviewing and

  12. Low enrichment fuel conversion for Iowa State University. Final report

    Bullen, D.B.; Wendt, S.E.

    1996-01-01

    The UTR-10 research and teaching reactor at Iowa State University (ISU) has been converted from high-enriched fuel (HEU) to low- enriched fuel (LEU) under Grant No. DE-FG702-87ER75360 from the Department of Energy (DOE). The original contract period was August 1, 1987 to July 31, 1989. The contract was extended to February 28, 1991 without additional funding. Because of delays in receiving the LEU fuel and the requirement for disassembly of the HEU assemblies, the contract was renewed first through May 31, 1992, then through May 31, 1993 with additional funding, and then again through July 31, 1994 with no additional funding. In mid-August the BMI cask was delivered to Iowa State. Preparations are underway to ship the HEU fuel when NRC license amendments for the cask are approved

    Full Text Available Italian and Russian Verse: Two Cultures and Two Mentalities The present text was given as a talk at Stanford University in 2003. Here the author presents a comparative analysis of Russian and Italian versification and pays attention to the cultural contacts between these two poetical traditions in an effort to define the role played by Italian patterns in Russian verse. In this perspective the author offers a history of Russian poetical translation of Italian texts pointing out the different opinions of Russian poets about the “musicality” of Italian verse. The combined influence of language and culture in modelling different Russian poetical forms in a chronological perspective is underlined.

  14. Pyrosequencing reveals high-temperature cellulolytic microbial consortia in Great Boiling Spring after in situ lignocellulose enrichment.

    Directory of Open Access Journals (Sweden)

    Joseph P Peacock

    Full Text Available To characterize high-temperature cellulolytic microbial communities, two lignocellulosic substrates, ammonia fiber-explosion-treated corn stover and aspen shavings, were incubated at average temperatures of 77 and 85°C in the sediment and water column of Great Boiling Spring, Nevada. Comparison of 109,941 quality-filtered 16S rRNA gene pyrosequences (pyrotags from eight enrichments to 37,057 quality-filtered pyrotags from corresponding natural samples revealed distinct enriched communities dominated by phylotypes related to cellulolytic and hemicellulolytic Thermotoga and Dictyoglomus, cellulolytic and sugar-fermenting Desulfurococcales, and sugar-fermenting and hydrogenotrophic Archaeoglobales. Minor enriched populations included close relatives of hydrogenotrophic Thermodesulfobacteria, the candidate bacterial phylum OP9, and candidate archaeal groups C2 and DHVE3. Enrichment temperature was the major factor influencing community composition, with a negative correlation between temperature and richness, followed by lignocellulosic substrate composition. This study establishes the importance of these groups in the natural degradation of lignocellulose at high temperatures and suggests that a substantial portion of the diversity of thermophiles contributing to consortial cellulolysis may be contained within lineages that have representatives in pure culture.

    Following a hiatus of several years and following its successful development and qualification of 4.8 g U cm -3 U 3 Si 2 -Al dispersion fuel for application with low-enriched uranium in research and test reactors, the US Reduced Enrichment for Research and Test Reactors program has embarked on the development of even-higher-density fuels. Our goal is to achieve uranium densities of 8-9 g cm -3 in aluminum-based dispersion fuels. Achieving this goal will require the use of high-density, γ-stabilized uranium alloy powders in conjunction with the most-advanced fuel fabrication techniques. Key issues being addressed are the reaction of the fuel alloys with aluminum and the irradiation behavior of the fuel alloys and any reaction products. Test irradiations of candidate fuels in very-small (micro) plates are scheduled to begin in the Advanced Test Reactor during June, 1997. Initial results are expected to be available in early 1998. We are performing out-of-reactor studies on the phase structure of the candidate alloys on diffusion of the matrix material into the aluminum. In addition, we are modifying our current dispersion fuel irradiation behavior model to accommodate the new fuels. Several international partners are participating in various phases of this work.

    1997-01-01

    Past practices associated with the civilian and military use of nuclear power in NW Russia present large environmental security risks of international concern. These risks arise from a variety of practices associated with weapons production, testing, power production and waste management. The threats presented by these activities are multimedia in nature, span political boundaries and cannot be simply or inexpensively remediated. Today, cooperative efforts are being undertaken to improve environmental security by remediating existing and potential emission sources. Initial efforts focused on the upgrade and expansion of the Murmansk Low-level Liquid Waste Treatment Facility, Murmansk, Russia. This facility handles wastes generated during the decommissioning of Russian Nuclear Navy submarines and from the operation of the Russian commercial nuclear-powered icebreaker fleet. This upgraded facility is now being constructed and is expected to be completed by March 1998. Completion of this facility will result in the cessation of any future dumping of liquid radioactive wastes into the Barents and Kara Seas. Another large environmental security risk is the LEPSE. The LEPSE is a ship docked in Murmansk, Russia, that contains ∼650 spent fuel elements as well as other solid and liquid wastes from Russian nuclear vessels. International efforts are now being mounted to remove the spent and damaged fuel from this ship, including the safe removal and storage/disposal of the fuel elements. This paper will summarize the environmental security problems presented by these different sources and the likely environmental security benefits associated with their remediation. 5 refs., 1 fig., 1 tab

    The Central Asian Orogenic Belt is a gigantic tectonic collage of numerous accreted terranes. However, its geodynamic evolution has been hotly debated primarily due to incomplete knowledge on the nature of these enigmatic terranes. This work presents new detrital zircon U-Pb and Hf isotopic data to constrain the crustal nature and origin of the Russian Altai, a critical segment of Altai-Mongolian terrane. The youngest zircon 206Pb/238U ages of 470 Ma constrain that the Terekta Formation, previously envisaged as Precambrian basement, was actually deposited after the Middle Ordovician. As for the three more sedimentary sequences above the Terekta Formation, they have youngest zircon 206Pb/238U ages of 425 Ma, 440 Ma and 380 Ma, respectively, indicating their depositions likely in the Late Silurian to Devonian. From all analyses, it is noted that many zircon U-Pb ages cluster at ca. 520 Ma and ca. 800 Ma, and these zircons display oscillatory zoning and have subhedral to euhedral morphology, which, collectively, suggests that adjacent Neoproterozoic to Paleozoic igneous rocks were possibly dominant in the sedimentary provenance. Additionally, a few rounded Archean to Mesoproterozoic zircon grains are characterized by complex texture, which are interpreted as recycling materials probably derived from the Tuva-Mongolian microcontinent. Precambrian rocks have not been identified in the Russian Altai, Chinese Altai and Mongolian Altai so far, therefore, Precambrian basement may not exist in the Altai-Mongolian terrane, but this terrane probably represents a large subduction-accretion complex built on the margin of the Tuva-Mongolian microcontinent in the Early Paleozoic.

During accretionary orogenesis of the CAOB, formation of such subduction-accretion complex is

    2015-12-01

    Biomedical knowledge resources (KRs) are mainly expressed in English, and many applications using them suffer from the scarcity of knowledge in non-English languages. The goal of the present work is to take maximum profit from existing multilingual biomedical KRs lexicons to enrich their non-English counterparts. We propose to combine different automatic methods to generate pair-wise language alignments. More specifically, we use two well-known translation methods (GIZA++ and Moses), and we propose a new ad hoc method specially devised for multilingual KRs. Then, resulting alignments are used to transfer semantics between KRs across their languages. Transference quality is ensured by checking the semantic coherence of the generated alignments. Experiments have been carried out over the Spanish, French and German UMLS Metathesaurus counterparts. As a result, the enriched Spanish KR can grow up to 1,514,217 concepts (originally 286,659), the French KR up to 1,104,968 concepts (originally 83,119), and the German KR up to 1,136,020 concepts (originally 86,842).

  4. Institutions and organisations in Russian higher education: the example of Rostov region education services market

    Directory of Open Access Journals (Sweden)

    Volchik Vyacheslav, V.

    2015-12-01

    Full Text Available The paper examines the process of transformation in institutional and organizational structures of Russian Higher Education (Rostov Region is taken as an example. Adaptive economic behavior of key actors on the Russian education services market has been studied in the context of constantly changing institutional and organizational environments. Original institutional approach in the tradition of J. Commons and J. Hodgson has been applied to analyze interconnections between institutions and organizations. The evolution of institutional and organizational structures in Russian Higher education has been divided into three stages. We distinguish between those stages taking into account the dynamics of quantitative indicators and the change in norms and standards that regulate actors’ behavior in the field. The period of 1990-2002 can be characterized by weakening of government regulation and, simultaneously, lack of financial support of Higher Education. Meanwhile, private Higher Education and paid university programmes developed rapidly during that period. These changes resulted in quantitative growth in the field on the one hand, and devaluation of Higher Education, on the other hand. It is assumed that the “bubble” in Russian Higher Education, which arose in 2002-2008, occurred to a great extent because of the expansion in extramural and lowquality full-time education aimed only at getting graduate diplomas. During the period of bubble formation and latter decline in demand on the Russian education services market, the Government strengthened norms and standards referring to regulation of Higher Education. Recent “optimization processes” of 2009-2015 resulted in reducing the number of students and lecturers, universities and their branches.

  5. HIGHLY ENRICHED URANIUM BLEND DOWN PROGRAM AT THE SAVANNAH RIVER SITE PRESENT AND FUTURE

    2008-01-01

    The Department of Energy (DOE) and Tennessee Valley Authority (TVA) entered into an Interagency Agreement to transfer approximately 40 metric tons of highly enriched uranium (HEU) to TVA for conversion to fuel for the Browns Ferry Nuclear Power Plant. Savannah River Site (SRS) inventories included a significant amount of this material, which resulted from processing spent fuel and surplus materials. The HEU is blended with natural uranium (NU) to low enriched uranium (LEU) with a 4.95% 235U isotopic content and shipped as solution to the TVA vendor. The HEU Blend Down Project provided the upgrades needed to achieve the product throughput and purity required and provided loading facilities. The first blending to low enriched uranium (LEU) took place in March 2003 with the initial shipment to the TVA vendor in July 2003. The SRS Shipments have continued on a regular schedule without any major issues for the past 5 years and are due to complete in September 2008. The HEU Blend program is now looking to continue its success by dispositioning an additional approximately 21 MTU of HEU material as part of the SRS Enriched Uranium Disposition Project

    2017-12-01

    Full Text Available In the Russian historiography, the views of the publicists of the early 20th century of the Russian colonists’ life in Central Asia aren’t duly highlighted. The novelty and aim of the research consist in revealing the general and particular in the Russian periodicals’ percep-tion of the colonization of Turkestan, in determining their ideological bent. The authors have discovered that all the reviewed periodicals were adherents of Central Asia colonization. They supported the imperial policy of the government with minor reserva-tions. Most publicists noted that the settling of colonists depended on the actions of the central government, which insuffi ciently took into account the local conditions. However, publicists differed in the choice of the main direction and in the assessments of the value of colonists’ adaptation activity; they proposed various ways of developing the intercultural dialogue.The authors come to the conclusions that liberal periodicals paid special attention to the economic activities of Russian immigrants, assessing the degree of their adaptation by the level of well-being achieved. The Narodnik periodicals considered migrants as a part of the peasant world of Russia. They were concerned, above all, about the colonists’ commu-nity, which they considered an effective means of adaptation, preserving the culture and moral qualities of the Russians. Probably, they considered it a pledge of building fair relations with the local population. Conservative and offi cial publicists viewed Russian immigrants primarily as support of the Russian government in Central Asia. That is why they paid special attention to the preservation of assimilation qualities of the Russians, the loss of which could become, in their view, an obstacle to the strengthening of the empire positions in the region.

  8. Management of Russian military plutonium

    1996-01-01

    The objective of this paper is to propose and discuss a solution which enables storing as quickly as possible all weapons-grade plutonium from Russian military program in a way which would prevent diversion. Two main conditions apply to this solution. First, it should be achieved in a manner acceptable to Russian government, notably by preserving plutonium for possible future energy production, and second, the economics of the total system should be good enough to ensure no charge or limited charge for the storage of plutonium. A proposal is made to store plutonium in a specially designed fast reactor or specially designed reactor core. This solution could be favorable in comparison to other solutions applying the above mentioned goal and conditions. Additionally the proposed solution would have the following side advantages: utilizing available personnel and installations of the Russian nuclear complex; providing possible basis for decommissioning of older and less safe Russian reactors; giving experience of construction and operation of a series of sodium-cooled fast reactors. The major problem however is the need for large capital investment with the risk of getting no adequate return on investment due to difficult political and economic situation in Russia

    The Russian Federation health system has its roots in the country's complex political history. The Ministry of Health and Social Development and its associated federal services are the principal Russian institutions subserving the Russian Federation. Funding for the health system goes through 2 channels: the general revenue budget managed by federal, regional, and local health authorities, and the Mandatory Health Insurance Fund. Although the Soviet Union was the first country in the world to guarantee free medical care as a constitutional right to all its citizens, quality and accessibility are in question.

    Full Text Available This study aims to point out the unexploited export potential of CEFTA economies to the Russian market, using both quantitative and qualitative methods. More precisely, the Russian food market is examined, because of its size, the lack of domestic supply and actual changes of trading partners due to political and security antagonisms. The competitiveness of CEFTA food production on the Russian food market was analyzed by using two classical instruments of competitiveness - coefficient of conformity (CC and real effective exchange rate (RER.CC is applied first to the CEFTA export and Russian import of food in total, and then to the six main Russian import food products. The results indicate the highest degree of matching between Russian import and all CEFTA country export of fruits, vegetable and its processed commodities. RER is calculated to show competitiveness in terms of prices in bilateral trade, and result shows a very favorable ratio of currency, except in the case of Montenegro and Bosnia because their fixation to euro. Due to the small size of CEFTA production and non-proportional large Russian market, the interconnection, e.g. forming the value chain made of CEFTAs agriculture and food industry companies is suggested as the basis of new CEFTA export strategy.

    2017-12-01

    Automated and semiautomated Twitter accounts, bots, have recently gained significant public attention due to their potential interference in the political realm. In this study, we develop a methodology for detecting bots on Twitter using an ensemble of classifiers and apply it to study bot activity within political discussions in the Russian Twittersphere. We focus on the interval from February 2014 to December 2015, an especially consequential period in Russian politics. Among accounts actively Tweeting about Russian politics, we find that on the majority of days, the proportion of Tweets produced by bots exceeds 50%. We reveal bot characteristics that distinguish them from humans in this corpus, and find that the software platform used for Tweeting is among the best predictors of bots. Finally, we find suggestive evidence that one prominent activity that bots were involved in on Russian political Twitter is the spread of news stories and promotion of media who produce them.

    The concentration of heavy metals and soil properties in fifty urban garden soils of Szeged (SE Hungary) were determined to evaluate the cumulative impacts of urbanization and cultivation on these soils. Using two enrichment factors (EFs) (based on reference horizon; Ti as reference element) and multivariate statistical analysis (PCA), the origin of the studied elements was defined. According to statistical coincidence of EFs confirmed by t-test, anthropogenic enrichment of Cu (EF = 4), Zn (EF = 2.7) and Pb (EF = 2.5) was significant in topsoils. Moreover, PCA also revealed the geogenic origin of Ni, Co, Cr and As and differentiated two groups of the anthropogenic metals [Pb, Zn] [Cu]. Spatial distribution of the metals visualized by GIS reflected the traffic origin of Pb; while based on ANOVA, the anthropogenic source of Cu is relevant (mainly pesticides) and there is a statistically significant difference in its concentration depending on land use. -- Highlights: ► We determined heavy metal concentrations in urban garden soils of Szeged, Hungary. ► We used different statistical methods, enrichment factors to identify metal origin. ► Enrichment degree and sources of anthropogenic metals were successfully evaluated. ► Anthropogenic enrichment of Cu, Pb and Zn was significant in urban garden topsoils. ► Traffic emission and soil cultivation together are responsible for metal enrichment. -- Metal enrichment and sources in urban garden soils due to urban activities and cultivation were successfully identified by combining more methods (enrichment factors, statistical analysis, spatial distribution)

    Rusnáková Soňa

    2017-10-01

    Full Text Available The main aim of this paper is to analyse the annexation of Crimea by the Russian Federation. For the purposes of the paper, the theory of hybrid warfare was chosen as an analytical category. Throughout the paper, the concept of hybrid warfare is examined and applied on case study of Crimean annexation. Hybrid warfare, especially in connection with Russian actions in Crimea has been an intensely debated concept. There is an ongoing debate among scholars concerning the meaning of the concept, its existence and employment by the Russian Federation. This paper showed that the article of Valeriy Gerasimov – the incumbent Chief of the General Staff of the Russian Federation-invoked a new warfare strategy for the Russian Federation which was consequently for the very first time in its full spectre and effectivity employed on case of Crimean annexation in March 2014. Observing the application of the hybrid warfare in practice serves the purposes of countering its further potential application in post-Soviet space and Russian ‘near abroad’.

    export margin. For Rosneft, the Sakhalin-1 project is an opportunity to gain a competitive edge on Gazprom and develop export capacity for future gas projects. In fact, the fierce competition developing between projects is a struggle to obtain the status of the 'most efficient and high-tech player' in the Russian gas market. Winning is evidently highly dependent on a number of key decisions by the country's leadership-who serve as a sort of ultimate arbitrator in this battle. Russian leadership is actively campaigning for the launch of LNG projects, and, despite all the obstacles and high costs, some will be completed by the end of this decade. Delivery times and costs, though significant, are not critical. While the return-on-investment for these projects, worth tens of billions of dollars, may be delayed, there is no doubt that sooner or later-in 15 to 20 years-they will pay off. Moreover, their strategic value in the eyes of the government is immense. Given the typical completion times for such projects globally, one can say with high certainty that full capacity utilization by these projects should not be expected before 2020. Until then, therefore, any attempts to diversify exports with LNG will be unsuccessful. In the longer term, between 2020 and 2030, Russia has considerable potential to strengthen its influence on the LNG market. However, despite future possibilities, the government's current intention to achieve 10% of the global LNG market by 2020 and 20% by 2030 is unrealistic. There is a long and winding road ahead. Russian LNG success will strongly depend on the ability of Russian market players to build up relations with the different groups of foreign partners. In seeking to gain a strong position in the global LNG market, Russia will have to change more and more its gas industry regulatory framework, opening it up for competition and international cooperation

Today V. Kitaev is a recognized expert on the history of Russian public thought and Professor of the Nizhny Novgorod State University. The article focuses on one of the most important, in the author’s opinion, outcome of long-term V. Kitaev’s studies of the history of Russian public thought of the 19th century – identifying the attempts of synthesis of its main directions: liberal, socialist, conservative. The desire for this synthesis was expressed by representatives of various trends of public thought, who wanted to avoid the revolutionary upheavals. V. Kitaev notes intertwining of both elements of liberalism and conservatism from M. Shcherbatov, who stood at the origins of Russian conservatism. In the pursuit of one of the ideologues of Russian liberalism, K. Kavelin reconciled the assumptions of Slavophilism and Westernism. V. Kitaev rightly saw a reflection of the heterogeneity of its ideological positions, representing a complex set of liberal and conservative elements. Taking into account the political and ideological self-evaluations of B. Chicherin (“guarding” liberalism, V. Kitaev proposed to consider him as a thinker and publicist, liberal-conservative centre left free to drift in the coordinate system. As shown by a scholar, a strong influence of socialist ideas was determined by the position of the liberal Vestnik Evropy (‘Herald of Europe’, the historical justice of which demands to put the formation of social liberalism in Russia in the beginning. The share of Russia is already fallen revolutions “from below” and revolutions “from above”. The Ways of Russian thought by V. Kitaev leads to a synthesis of the best intellectual legacy that we inherited from the nineteenth century. Maybe this is the way to our national reconciliation and unity.

    English and Russian are two different orthographies, the former being an opaque orthography, the latter being considered a direct letter-sound language. This study investigated the relationship between reading, syntactic, orthographic, and working memory skills in the two orthographies. Participants were first-year BA students of English (age range 25-30) at the University of Haifa who had completed high school in Russia. They were tested individually, in Russian and English, on working memory, spelling, oral cloze, visual condition, phonological condition, orthographic skills, word attack, and word identification. The results indicated positive significant correlations within and across languages, except for the orthographic skills and some of the correlations of the visual skills. The orthographic skills correlated highly significantly within each language but not across languages. Almost all the other linguistic skills correlated significantly within and across languages. Multiple regression procedures revealed that phonological and spelling skills in Russian, the first language, were strong predictors of word identification in English, the second language. These results are discussed in light of the interdependence and the script-dependent hypotheses.

    The feasibility of using a standard AWCC at the Obninsk IPPE has been demonstrated through active measurements of single UO 2 (36% enriched) disks and through passive measurements of plutonium metal disks used for simulating reactor cores. The role of the measurements is to verify passport values assigned to the disks by the facility, and thereby facilitate the mass accountability procedures developed for the very large inventory of fuel disks at the facility. The AWCC is a very flexible instrument for verification measurements of the large variety of nuclear material items at the Obninsk IPPE and other Russian facilities. Future work at the IPPE will include calibration and verification measurements for other materials, both in individual disks and in multi-disk storage tubes; it will also include training in the use of the AWCC

    Full text of publication follows: For some applications in fusion devices austenitic stainless steels are still considered to be candidates for use as structural components, but high neutron exposures must be endured by the steels. Operational experience of fast reactors in Western Europe, USA and Japan provides evidence of the possible use of austenitic steels up to ∼ 150 dpa. Studies aimed at improvement of existing Russian austenitic steels are being carried out in Russia. For improvement of irradiation resistance of Russian steels it is necessary to understand the basic mechanisms responsible for deterioration of steel properties. This understanding can be achieved by continuing detailed investigations of the microstructure of cladding steels after irradiation to high doses. By investigating the evolution of radiation-induced microstructure in neutron irradiated steels of different chemical composition one can study the effect of chemical variations on steel properties. Silicon is one of the most important chemical elements that strongly influence the behavior of austenitic steel properties under irradiation. In this paper results are presented of investigations of the effect of silicon additions on void swelling and microstructure of base austenitic stainless steel EI-847 (0.06C-16Cr-15Ni- 3Mo-Nb) irradiated as fuel pin cladding of both regular and experimental assemblies in the BOR-60, BN-350 and BN-600 fast reactors to neutron doses up to 49 dpa. The possible mechanisms of silicon's effect on void swelling in austenitic stainless steels are presented and analyzed. (authors)

    Full Text Available The paper presents the materials of the Russian Arthritis Registry (OREL that includes 3276 patients from 11 Russian Federation's largest research-and-practical centers situated in Moscow, Saint Petersburg, Novosibirsk, Kazan, Tula, Yaroslavl, Tyumen. It discusses the main goals of setting up registries, compares the results of an analysis of the data available in the Russian Registry OREL and registries of European countries and the USA. The findings suggest that there is non-uniform information on clinical, laboratory, and instrumental parameters in the national registers of a number of European countries and the USA. According to its basic characteristics, the Russian Registry OREL compares favorably with a number of other registries in the completeness of data collection, which allows a general idea of rheumatoidarthritis (RA patients in Russia. For further development of the OREL Registry, it is necessary to concentrate our attention on the following main areas: to improve the quality of filling out documents; to follow-up patients receiving different RA therapy regimens according to the guidelines of the Association of Rheumatologists of Russia for the treatment of RA; to conduct in-depth studies of comorbidity, primarily depressive disorders; to analyze adverse reactions that make RA therapy difficult; to actively use modules for patients' self-rating of their condition; to develop nursing care, etc.

    The buyer's market of today will continue, and buyer confidence and independence will probably grow. The emergence of indigenous suppliers and the expiration of long-term contracts could result in primary suppliers offering more and more of their excess capacity on the secondary market. But US legal and legislative complications could introduce a number of important caveats about what form or origin or quantity of material can be enriched by the largest enrichment supplier and for the largest single market.

    Full Text Available The article analyses the reasons that prevent a competitive export-oriented Russian domestic development of the robot surgical complex from being industrially prototyped and serially released for the domestic and global market. The development is completed within the framework of a «priority project» which was also highlighted as of significant importance in the Forecast analysis of the scientific-technological development of Russia for the period of up until 2030 and in the road maps of the National technological initiative and other strategic documents. The project was financed by nearly all development funds and institutes in Russia. A conclusion is drawn that the key reason behind the significant increase in a life span of a high-tech market product is the absence of a target setting and a programme of coordinated actions from committed ministries and governmental agencies, as well as the lack of a large high tech company in Russia, capable of producing in industrial volumes the export-oriented products and ensure their global sales.

  17. Supply of enriched uranium for research reactors

    International Nuclear Information System (INIS)

    Mueller, Hans; Laucht, Juergen

    1996-01-01

    Since the RERTR meeting in 1990 at Newport/USA, NUKEM recommended that the research reactor community agree upon a worldwide unified technical specification for low enriched uranium (LEU) and high enriched uranium (HEU) since there existed numerous specifications both from suppliers/fabricators and research reactors. The target recommended by NUKEM is to arrive at a worldwide unified standard specification in order to facilitate supplies of LEU and HEU to fabricators for fabrication of research reactor fuel elements. In our paper presented at the RERTR meeting at Paris in September 1995, we pointed out that LEU and HEU supplied by the U.S. Department of Energy (DOE) in the past was never 'virgin' material, i.e., it was mixed with reprocessed uranium. Our recommendation was to include this fact in the proposed unified specification. Since the RERTR meeting in 1995 progress on a unified standard specification has been made and we would like to provide more specific information about that in this paper. Furthermore, we will deal with the question whether there is a secure supply of LEU for converted research reactors. We list current and potential suppliers of LEU, noting however, that the DOE has for a number of years been unable to supply any LEU due to production problems. The future availability of LEU of U.S. origin is, of course, essential for those research reactor operators which have converted their reactors from HEU to LEU and which are intending to return spent fuel of U.S. origin to the U.S.A.

    Full Text Available It has been three years since the impose of anti-Russian sanctions and claimed turn to the East. It is possible to sum up some results of this politics already. Top-priority in such circumstances is China, world’s second large economy; Russian-Chinese relations “are now the best ever”. Leaders of both countries have focused on the importance of maintaining strategic partnership multiple times. While Russia turned to The East, China also chose turn to the West by declaring global “One belt — One road” initiative for development of worldwide transport and investment infrastructure in Eurasia. Moscow is the partnership of the Initiative. It was decided to cooperate in frames of Eurasian Economic Union (EAEU and Silk Road Economic Belt. However, such a high level of political communication cannot guarantee the same results in bilateral trade and economic relations. Main projects, which were agreed with the involvement of the top-officials, are in progress. Businessmen mostly have to handle with all the problems to enter new Chinese market by themselves. In addition, despite all the efforts Russia is still not developing the same good connection with other Asian countries, except Japan, South Korea and Vietnam.

    The article covers the issue of high-rise buildings (skyscrapers) construction in Russia as the dialogue of artistic image and intellectual idea. The study shows that the professional commitment to skyscrapers erection brings to the foreground the comprehension of magnitude of the notion of "contemporary" in terms of time. It is important from methodical point of view to return to the initial meaning of the notions that provide for adding authentic meaning to the words "suprematism", "commitment", "excellence", "new", "high", and other determinants of creativity capable of going beyond "flying geese" development pattern in architectural shaping. It is well known that V.G. Shukhov's patents of 1896 were widely used in contemporary morphology of shaping. The heritage of Russian Avant Garde of 1910-20ies serves as an inspiration from methodological point of view (it is more and more evident from foreign master's creative experience). This is why it is important to return, first of all, to comprehension of the author's version of the notion "suprematism" ascending to Malevich - meaning commitment to excellence and not the "emblem" of preferences in style. The article includes the arguments providing for the capture of the 2010ies and, especially, 2015-17ies as the years of critical changes in history. Russian masters of architecture started as equals the stage of cooperative creative work with foreign architects erecting skyscrapers.

    Uranium enriched to 90-93%, supplied by the U.S., is now used in 141 research and test reactors in 35 countries around the world with a cumulative power of 1714 mw. Since of the order of 3 kg of 235 U is involved annually in fuel fabrication, fresh fuel transport and storage, reactor operation, and spent fuel cooling and return per megawatt of research reactor power, it is estimated that more than 5000 kg of very high-enriched uranium is handled each year to operate these reactors. Recent U.S. assessments have led to the tentative conclusion that in only approximately 11 of these reactors, generally those of highest power or power density, is the use of 90-93% enriched uranium currently a technical necessity. Universal use of the best state-of-the-art fuel technology would permit an estimated 90 of these reactors to use 20% enriched fuel, and estimated 40 others to use 45% enriched fuel, without significant performance degradation. If advanced research reactor fuel development programs currently under way in the U.S. and elsewhere are successful, it may, in fact, be possible to operate virtually all of these reactors on less than 20% enriched uranium in the longer term. The physical and economic practicality of these developmental fuels must, of course, await future assessments

    Full Text Available Publication practices in Russian psychology have changed a lot since the break-up of the Soviet Union, but still differ substantially from those in the Western countries. In the last decade, an exponen-tial growth of the number of scientific psychological journals was observed, but in general, scientific publishing is not a profitable business in Russia. There is a lot of variability in the accessibility and quality of the journals. In sum, psychological publishing in today’s Russia is not well developed. Open access (OA publishing technologies seem to bring clear benefits to Russian psychology, but there are some problems that prevent their ready acceptance. First, there is a linguistic problem – Russian read-ers and writers have bad command of foreign languages. Second, there is a problem of background – Russian readers and writers are not used to Western-style research papers. Third, there is an economic problem – it is unclear, whether Russian universities and funding agencies will ever be ready to support publications in OA-journals. Thus, self-archiving and no-fee OA seem to be the most obvious ways to introduce OA to Russian psychologists.

  5. Enrichment of deuterium in insoluble organic matter from primitive meteorites: A solar system origin?

    Because of a systematic enrichment in deuterium, the insoluble organic matter (IOM) of the carbonaceous chondrites is considered to have formed in the interstellar medium. However, the D / H ratios in IOM remain much lower than those measured in the organic molecules commonly observed in the dense interstellar medium. In this study, the D / H ratio of different aromatic and aliphatic molecular fragments of IOM from the Orgueil meteorite was measured by GC-irMS (gas chromatography-isotopic ratio mass spectrometry). No correlation was observed between the D / H ratios and structural parameters characterizing the IOM, such as the H / C ratio. However, the δD of the benzylic, aliphatic and aromatic hydrogen into the IOM can be determined to be 1250‰, + 550‰ and + 150‰, respectively, relative to SMOW. This indicates that D-enrichment in IOM is correlated with the C-H bond dissociation energy. Such a correlation rules out IOM formation from observed interstellar molecules and suggests instead that the different components of IOM have acquired their D / H ratios by an exchange with a deuterium-rich reservoir after its synthesis. The same process can be invoked to account for the D / H composition of meteoritic water. Findings point to a common process for deuterium enrichment in the solar system.

    Laser Isotope Enrichment for Medical and Industrial Applications by Jeff Eerkens (University of Missouri), Jay Kunze (Idaho State University), and Leonard Bond (Idaho National Laboratory) The principal isotope enrichment business in the world is the enrichment of uranium for commercial power reactor fuels. However, there are a number of other needs for separated isotopes. Some examples are: 1) Pure isotopic targets for irradiation to produce medical radioisotopes. 2) Pure isotopes for semiconductors. 3) Low neutron capture isotopes for various uses in nuclear reactors. 4) Isotopes for industrial tracer/identification applications. Examples of interest to medicine are targets to produce radio-isotopes such as S-33, Mo-98, Mo-100, W-186, Sn-112; while for MRI diagnostics, the non-radioactive Xe-129 isotope is wanted. For super-semiconductor applications some desired industrial isotopes are Si-28, Ga-69, Ge-74, Se-80, Te-128, etc. An example of a low cross section isotope for use in reactors is Zn-68 as a corrosion inhibitor material in nuclear reactor primary systems. Neutron activation of Ar isotopes is of interest in industrial tracer and diagnostic applications (e.g. oil-logging). . In the past few years there has been a sufficient supply of isotopes in common demand, because of huge Russian stockpiles produced with old electromagnetic and centrifuge separators previously used for uranium enrichment. Production of specialized isotopes in the USA has been largely accomplished using old ”calutrons” (electromagnetic separators) at Oak Ridge National Laboratory. These methods of separating isotopes are rather energy inefficient. Use of lasers for isotope separation has been considered for many decades. None of the proposed methods have attained sufficient proof of principal status to be economically attractive to pursue commercially. Some of the authors have succeeded in separating sulfur isotopes using a rather new and different method, known as condensation

    Full Text Available He article is devoted to the role of the Russian language in Central Asia and its development perspectives in the context of the Eurasian integration processes. Russian language has a long historical tradition in Central Asia and hasn't lost its importance even at the background of two waves of "derussification" that took place after 1991. Notwithstanding the decrease of the status, it keeps substantial public significance. During last two decades only in Turkmenistan we are witnessing the decrease in spreading of the Russian language among title population of the Central Asia region. Its positions as an active communication channel is secured not only by the social tradition, but also by the competitiveness of the Russian language education, advantages of the bilingual business, requirements of the labor migrants, HR interests and by some other pragmatic thoughts, which role within the context of Eurasian economic integration will increase. Despite the difficulties, it is too early to speak about the decrease of the Russian language in the Central Asia region. It is more likely that the institutes itself that maintain it and promoting it are at the low ebb. New scales and forms of practical work that is interested not only for Russia, but also Central Asia countries are required. Pressure on the resources of the Russian language increases the possibility of ethnic conflicts and strengthens the positions of political radicalism in Central Asia region.

    Full Text Available The author assesses the impact of the Yuan exchange rate volatility on the indicators of the Russian-Chinese trade (the analysis is made on the ground of the statistical database CEIC. Quantitative estimates of changes in Russian-Chinese merchandise trade by commodity groups (in the HS classification due to the revaluation of the CNY against the USD were obtained via the regression analysis. In the case of the revaluation of the Yuan to the US dollar the value of Russian exports may increase for such commodity groups as mineral products, chemical industry products, base metals, precious stones and metals, and vehicles. This article shows that the value of Chinese imports will decrease for such merchandise groups as transport vehicles, machinery and equipment, leather industry products, non-precious metals and products from them; in this case, the import of the food industry products, mineral products and optical instruments will decrease insignificantly. The author concludes that the revaluation of the Yuan, contributing to the growth of Russian exports and the reduction in Chinese imports, will not cause a radical change in structure of the Russian-Chinese trade

    The Diagnostic Interview for Psychoses (DIP) was developed to enhance the quality of diagnostic assessment of psychotic disorders. The aim of the study was the adaptation of the Russian language version and evaluation of its validity and reliability. Ninety-eight patients with psychotic disorders (89 video recordings) were assessed by 12 interviewers using the Russian version of DIP at 7 clinical sites (in 6 cities of the Russian Federation). DIP ratings on 32 cases of a randomized case sample were made by 9 interviewers and the inter-rater reliability was compared with the researchers' DIP ratings. Overall pairwise agreement and Cohen's kappa were calculated. Diagnostic validity was evaluated on the basis of comparing the researchers' ratings using the Russian version of DIP with the 'gold standard' ratings of the same 62 clinical cases from the Western Australia Family Study Schizophrenia (WAFSS). The mean duration of the interview was 47±21 minutes. The Kappa statistic demonstrated a significant or almost perfect level of agreement on the majority of DIP items (84.54%) and a significant agreement for the ICD-10 diagnoses generated by the DIP computer diagnostic algorithm (κ=0.68; 95% CI 0.53,0.93). The level of agreement on the researchers' diagnoses was considerably lower (κ=0.31; 95% CI 0.06,0.56). The agreement on affective and positive psychotic symptoms was significantly higher than agreement on negative symptoms (F(2,44)=20.72, pRussian language version of DIP was confirmed by 73% (45/62) of the Russian DIP diagnoses matching the original WAFSS diagnoses. Among the mismatched diagnoses were 80 cases with a diagnosis of F20 Schizophrenia in the medical documentation compared to the researchers' F20 diagnoses in only 68 patients and in 62 of the DIP computerized diagnostic outputs. The reported level of subjective difficulties experienced when using the DIP was low to moderate. The results of the study confirm the validity and reliability of the Russian

    Full Text Available The work over the system of documents, relating to the “spatial slice” of the strategic planning, has greatly enriched the ideas, concerning the instruments of spatial regulation of the economy, made it possible to carry out their classification and to specify the target function of each of these tools according to the concrete circumstances of different types of Russian regions. In this connection, it is extremely important to ensure flexible utilization of such an instrument of this policy as “growth points”. However, the task of improving branch and spatial structure of the Russian economy cannot be solved only via the growing number and variety of “growth points”, which at present chiefly act in the status of the various territorial “development institutions”. The accumulated positive and negative experience indicates the need of flexible implementation of these “points of growth”, objective function and mechanisms of which should be correlated with the development priorities for economically different types of regions. The main approaches to this task should be proposed in the Strategy of spatial development of the Russian economy, which is designed to provide the classification of “points of growth”, principles of their localization, consistent with the specifics and strategic priorities of economic and social development of individual regions and macro-regions of Russia.

    Field trials have demonstrated that the analysis of particles upon swipes obtained from inside nuclear installations provides clear signatures of past operations in that installation. This can offer a valuable tool for gaining assurance regarding the compliance with declared activities and the absence of undeclared activities (e.g. enrichment, reprocessing, and reactor operation) at such sites. This method, known as 'Environmental Sampling' (ES) or 'High Performance Trace Analysis' (HPTA) in EURATOM terminology, is at present being evaluated by the EURATOM Safeguards Directorate (ESD) in order to assess its possible use in nuclear installations within the European Union. It is expected that incorporation of HPTA/ES of sample collection and analysis into routine inspection activities will allow EURATOM to improve the effectiveness of safeguards in these installations and hopefully save inspection resources as well. The EURATOM Safeguards Directorate has therefore performed implementation trials involving the collection of particles by the so-called swipe sampling method in uranium centrifuge enrichment plants and hot cells in the European Union. These samples were subsequently analysed by the Joint Research Centre, Institute for Transuranium Elements (ITU) in Karlsruhe. Sampling points were chosen on the basis of the activities performed in the vicinity and by considering the possible ways through which particles are released, diffused and transported. The aim was to test the efficiency of the method as regards: the collection of enough representative material; the identification of a large enough number of uranium particles; the accurate measurement of the enrichment of the uranium particles found on the swipe; the representativity of the results in respect of past activities in the plant; the capability of detecting whether highly enriched uranium has been produced, used or occasionally transported in a location where low enriched uranium is routinely produced in

    Full Text Available Both Russian and non-Russian composers and music critics willingly used the notion of Russian exoticism to differentiate the Russian musical legacy from the (western European tradition, especially in the 19th century. At the same time, various Russian musical practices were considered to be exotic in Russia itself. In this article it is suggested that these two perceptions of Russian music influenced each other, having an impact on the formation of Russian national music. It is further claimed that Russian music served both as an internal and external tool for defining the country’s musical culture on the multicultural map of Europe.

    An ''Assessment of the Impact of Russian Nuclear Fleet Operations on Far Eastern Coastal Regions'' is being performed as part of the Radiation Safety of the Biosphere Project (RAD) of the International Institute for Applied Systems Analysis (IIASA) of Laxenburg, Austria. To the best of our knowledge, this is the first comprehensive unclassified analysis of the potential impact of accidents at the Russian Far East nuclear submarine sites near Vladivostok and Petropavlovsk. We have defined the situation there based upon available information and studies commissioned by RAD in collaboration with Russian research institutes including Russian Research Center-''Kurchatov Institute'', Institute of Northern Environmental Problems and Lazurit Central Design Bureau. Further, in our original work, some in collaboration with the staff of the Danish Meteorological Institute (DMI) and members of the Japan Atomic Energy Research Institute, we have calculated the nuclide trajectories from these sites in the atmospheric boundary layer, less than 1.5 kilometers high, and determined their probability of crossing any of the nearby countries as well as Asiatic Russia. We have further determined the concentrations in each of these crossings as well as the total, dry and wet depositions of nuclides on these areas. Finally, we have calculated the doses to the Japanese Island population from typical winter airflow patterns (those most likely to cross the Islands in the minimum times), strong north winds, weak north winds and cyclonic winds for conditions similar to the Chazhma Bay criticality accident (fresh fuel) and for a criticality accident for the same type of reactor with fuel being withdrawn (spent fuel). The maximum individual committed dosages were less than 2 x 10-7 and 2 x 10-3 mSv, respectively. The long-term external doses by radionuclides deposited on the ground and the internal doses by consumption of foods were not evaluated as it is

    Third party and environment of civil liability damage caused by incidents at military nuclear installations, for instance at decommissioned NPS (nuclear powered submarines), may be divided into three main trends: -) Liability of NPS without high-enriched irradiated nuclear fuel (SNF) for its self-submersion (radiation incident); -) Liability of NPS with SNF aboard for its self-submersion (radiation incident); and -) Liability of floating NPS for its SNF discharge (nuclear accident). Without step-by-step transition from the Russian Federation guaranties to insurance and making allowance for liability limits according to the Vienna Convention approach, the sizes of the financial guarantee for the civil liability of the NPS owner (Russian state), in US dollars of 2000, are approximately assessed as the following: -) storing decommissioned NPS or a floating module without SNF - from 12 to 25 thousand dollars per year (per one submarine or module); -) storing decommissioned NPS with SNF inside reactors cores - from 25 to 40 thousand dollars per year; -) assembly-by-assembly removing SNF from reactors' core of decommissioned NPS - up to 1.5 million dollars for undamaged reactor per the discharging period; -) SNF removing within reactor using the filled in-space reactor's core by liquid-phased hardened or dispersed solid-phase materials from decommissioned NPS - from 30 to 50 thousand dollars for undamaged reactor per the discharging period. Both rates and sums for NPS with damaged reactors are to be estimated for the each damaged reactor and NPS at all. It is necessary to perform the measures reducing the risk of nuclear accidents of NPS with undamaged SNF and NPS with damaged reactors in possibly short time.

    Either highly enriched uranium (HEU) or plutonium is needed to construct a nuclear weapon. While plutonium is radioactive and hazardous in handling, HEU is far less dangerous. Furthermore, it is more difficult to detect by technical means. Therefore, in comparison to plutonium, HEU is much easier to divert, smuggle and hide. Moreover, a crude nuclear explosive made of HEU can be constructed in a much simpler way than one made using plutonium. For these reasons, HEU is the material most wanted by terrorists. A few tens of kilograms are sufficient for one explosive, but the quantities existing in the world add up to hundreds of tons. Due to the disarmament at the end of the Cold War, the NPT nuclear weapon states possess large quantities of HEU in excess of their needs for nuclear weapons. Therefore, these countries have not produced HEU for many years. Several international projects are working towards reducing the proliferation risks posed by HEU. The projects include the reduction of existing HEU by converting it to civilian reactor fuel that cannot be easily used for nuclear weapons. Other projects work towards reducing the number of countries and sites where HEU is stored by transferring it back to the countries of origin. And there are yet other projects which seek to minimize uses which would require new production of HEU. An international non-proliferation goal should be to eliminate all uses of HEU and thus to eliminate the need for any future production. Uses of HEU other than for nuclear weapons are as fuel in civilian research reactors, as base material for the production of special isotopes used in medical diagnostics, so-called medical targets and as fuel in military naval reactors. It is desirable to replace the HEU in all these applications with other materials and thus cease all HEU production forever. Use as fuel in civilian reactors has been greatly reduced during the last few decades. Within an international campaign, the Reduced Enrichment for

    Benchmark criticality experiments of fast heterogeneous configuration with high enriched uranium (HEU) nuclear fuel were performed using the 'Giacint' critical assembly of the Joint Institute for Power and Nuclear Research - Sosny (JIPNR-Sosny) of the National Academy of Sciences of Belarus. The critical assembly core comprised fuel assemblies without a casing for the 34.8 mm wrench. Fuel assemblies contain 19 fuel rods of two types. The first type is metal uranium fuel rods with 90% enrichment by U-235; the second one is dioxide uranium fuel rods with 36% enrichment by U-235. The total fuel rods length is 620 mm, and the active fuel length is 500 mm. The outer fuel rods diameter is 7 mm, the wall is 0.2 mm thick, and the fuel material diameter is 6.4 mm. The clad material is stainless steel. The side radial reflector: the inner layer of beryllium, and the outer layer of stainless steel. The top and bottom axial reflectors are of stainless steel. The analysis of the experimental results obtained from these benchmark experiments by developing detailed calculation models and performing simulations for the different experiments is presented. The sensitivity of the obtained results for the material specifications and the modeling details were examined. The analyses used the MCNP and MCU computer programs. This paper presents the experimental and analytical results. (authors)

    Isotopic and trace element geochemical studies of ocean island basalts (OIBs) have for many years been used to infer the presence of long-lived ({approx} 1-2 Ga old) compositional heterogeneities in the deep mantle related to recycling of crustal lithologies and marine and terrigenous sediments via subduction [e.g., Zindler, A., Hart, S.R., 1986.

    Full Text Available This paper empirically analyses the determinants of foreign direct investment inflows into the Russian regions. This problem has become highly relevant for the necessary modernization of the Russian economy after the recent economic slowdown and sharp decrease in budget revenues. The authors model foreign direct investment flows with the use of the gravity approach according to which investment flows are positively correlated with the size of the investor’s country as well as the size of the recipient region and are negatively correlated with the distance between investor and recipient. The empirical analysis is based on a constructed database consisting of the foreign direct investment flows from 179 investor countries into 78 Russian regions for the period 2006–2013. The authors apply the Poisson Pseudo Maximum Likelihood method and identify the following factors determining foreign direct investment inflows into the Russian economy: the gross domestic product of the investor’s country, the gross domestic product per capita in the recipient region, the distance from the investor to Moscow, the openness of the region, the economic situation in the region, the innovative capacity of the region and the foreign direct investment of the previous period. Interestingly, the distance from the recipient region to Moscow matters for the regions in the western part of Russia (relatively close to Moscow but is not significant for the regions in the eastern part (remote regions.

    Full Text Available In Russia defensive works were not less important than in Western Europe. Russian chronicles are full of reports of the building of towns, of their siege and defence. In Ancient Russian the word town meant not a town in the modern sense, but only a fortified settlement as distinct from an unfortified one. Thus the concept town applied to medieval towns proper and to citadels, feudal castles and even fortified villages. Every population centre with a wall round it was called a town. Moreover, until the 17th century this word was frequently applied to mean the fortifications themselves.

    The Soviet communist regime had devastating consequences on the state of Russian twentieth century science. Country Communist leaders promoted Trofim Lysenko--an agronomist and keen supporter of the inheritance of acquired characters--and the Soviet government imposed a complete ban on the practice and teaching of genetics, which it condemned as a "bourgeois perversion". Russian science, which had previously flourished, rapidly declined, and many valuable scientific discoveries made by leading Russian geneticists were forgotten.

    Full Text Available The purpose of the study is to evaluate the strength and direction of the distribution of the foreign direct investments (FDI in regional economy. The subject matter of the research is FDI to the regions of Russia. The subject of the study is relevant as it makes possible to estimate the long-term consequences from the restrictions of the West countries (in connection with sanctions against the inflow of the foreign capital to the regions of the Russian Federation. The study is based on the following hypotheses: 1. Russian regional economy has horizontal (distribution of effects from FDI within an industry and vertical spillover effects (distribution according to a technological chain, from product suppliers to product consumers. Vertical effects are more important and have greater amplitude than horizontal effects. An industry competition is one of the causes of negative horizontal spillover effect, and the scale of the company is the reason of positive horizontal spillover effect. 2. FDI generates the positive regional spillover effects on the productivity of domestic firms in the Russian economy. 3. Regional industry specificity influences the sign and magnitude of spillovers from FDI. 4. Time sensitivity is revealed for horizontal spillovers, so the regional effects may change the direction. As an empirical basis of the study, the statements of 23567 Russian companies with FDI and 25354 Russian enterprises without FDI for the 5 years were used. The methodology of the research is the calculation of spillover effects, Cobb-Douglas production function and panel data regression. The study has found, that the direct vertical spillover effects are almost absent. That means that industrial consumers do not notice the effect of inward FDI. At the same time, the converse effect related to the product suppliers is positive, but as the direct effect, it is not more important in any group of regions then the horizontal effect.

    In this study, N-enriched multilayered porous activated carbon (LPAC), using natural casings as precursor, was fabricated by a facile carbonization and subsequent KOH activation procedure. The influence of the mass ratio of KOH to carbonized material on pore-structure and surface element composition of LPACs was investigated by a variety of means, such as SEM, HRTEM, BET, Raman, XRD, XPS and XAS. Owing to the unique multilayered texture and nitrogen (N) and oxygen (O) rich feature of natural casings, the resulting LPACs possess interconnected and developed porous structure with N- and O-enriched functional groups, contributing to larger pseudocapacitance. With the rise of mass ratio, the specific surface area (SSA) and average pore size of LPACs increased. The final materials were endowed with a desirable SSA (3100 m2 g-1) and high N content (6.34 at.%). Meanwhile, N- and O-enriched LPAC-4 exhibited a high specific capacitance (307.5 F g-1 at a current density of 0.5 A g-1 in 6 M KOH aqueous solution), excellent rate performance (63.4% capacitance retention at 20 A g-1) and good cycling stability (7.1% capacitance loss after 5000 cycles). Furthermore, the assembled symmetrical supercapacitor (LPAC-4//LPAC-4) with a wide voltage window of 1.4 V delivered a remarkable energy density of 11.6 Wh kg-1 at a power density of 297 W kg-1. These results suggested that unique LPACs derived from natural casings are a promising material for supercapacitors.

Now, in a F.S.V. geometry, a comparison is made between Thorium cycle and Uranium cycle. This comparison will be concerned with the physical properties of the materials, the needs of natural Uranium, the fissile material inventory and, at last, an attempt of economical considerations. In this report the cycle will be characterizd by the fertile material. So, we write ''Thorium cycle'' for Highly Enriched Uranium - Thorium cycle and ''Uranium cycle'' for low Enrichment Uranium cycle.

    Oxygen enriched combustion technology has recently been used in waste incineration. To apply the oxygen enrichment on alpha-bearing waste incineration, which is being developed, a state-of-an-art review has been performed. The use of oxygen or oxygen-enriched air instead of air in incineration would result in increase of combustion efficiency and capacity, and reduction of off-gas product. Especially, the off-gas could be reduced below a quarter, which might reduce off-gas treatment facilities, and also increase an efficiency of off-gas treatment. However, the use of oxygen might also lead to local overheating and high nitrogen oxides (NOx) formation. To overcome these problems, an application of low NOx oxy-fuel burner and recycling of a part of off-gas to combustion chamber have been suggested

    Full Text Available The article focuses on the symbolic meaning of Russian ringing of bell in the Russian discourse. According to Lotman’s definition of symbol, it has dual nature: an invariant essence and its modification in relation to the cultural context. The article introduces informative and linguistic modifications of the bell topic in the Russian poetic discourse of the 19th, the 20th and the beginning of the 21st century. The author of the article provides the detailed analysis of such discursive descriptions of bell ringing as the ringing of church bells and alarm . The author arrives at the conlusion that the alarm topic prevails in contemporary poetry and this indicates the state of public dissatisfaction. In the 19th and the 20th centuries lexemes the ringing of church bells and alarm were used literally, but in the 21st century lexeme alarm acquires metaphorical meaning of call for blood.

  4. Russian oil prices: courting the world market

    Khartukov, E.M.

    1995-01-01

    The export and oil pricing of Russian crude was discussed. Russian crude and oil product exports are not yet wholly competitive with world oil markets. It was suggested that to do so, would be neither desirable nor actually possible at present. The reason for this is related to Russia's export duties regime and Russia's trade with its neighbouring countries which include the former Soviet republics. In the first half of 1995, the average border price of crude destined for those countries was US$75.04/tonne as opposed to US$114.77/tonne for crude exported to 'far-abroad', hard-currency markets. A breakdown of Russia's export duties for liquid fuels and a typical breakdown of export and domestic prices for Russian oil was provided. Russian crude is considerably under-priced mainly because of the poor state of the national refining industry which is in need of radical modernization. It was suggested that instead of globalization, it would be more appropriate to redirect the priorities of Russian energy policy towards defining optimal use of Russia's available energy potential, and rationalizing its domestic price structure first, which is the root cause of the national price problem. 5 refs., 5 tabs., 2 figs

    This Conversion and Blending Facility (CBF) will have two missions: (1) convert HEU materials into pure HEU oxide and (2) blend the pure HEU oxide with depleted and natural uranium oxide to produce an LWR grade LEU product. The primary emphasis of this blending operation will be to destroy the weapons capability of large, surplus stockpiles of HEU. The blended LEU product can only be made weapons capable again by the uranium enrichment process. To the extent practical, the chemical and isotopic concentrations of blended LEU product will be held within the specifications required for LWR fuel. Such blended LEU product will be offered to the United States Enrichment Corporation (USEC) to be sold as feed material to the commercial nuclear industry. Otherwise, blended LEU will be produced as a waste suitable for storage or disposal.

Examples of modern Russian and foreign high-rise construction are considered in the work. The most important problems and their solutions for Russia are identified on their basis. The everyone area of concern is considered separately. Ecology problems and influence of high-rise construction for the healthy and psychological effect of people are considered special. High-rise constructions influence negative and positive for urban environment in Moscow and Samara cities. The experience lack, defects in requirements document, which don't include all high-rise constructions specific, system problem of construction and often non-availability of proper control at the existing requirements document result for complexity of designing, construction and operation. At this moment, high-rise constructions temp is increasing in Moscow. Feasibility of high-rise buildings come up in regions of Russia. The reasons include high material inputs, irregularities of requirements network and utility lines and maintenance problems. The researching follow up of conclusions and recommendations for high-rise constructions development in Russia. The reasons of high-rise buildings are urbanization of people and necessary of concentration labor supply. The important tasks for organization are creating compact urban environment, decrease urban area for development, using an innovative technology for construction and properly maintenance. The balance between the preference of high-rise construction, inputs for construction and influence for ecology are resolve for this task.

    Several Cord Blood (CB) Bank studies suggested that ethnicity impaired CB unit (CBU) qualification. The Bone Marrow Donors Worldwide registries present an over-representation of unrelated donors (UD) from Northwestern European descent. This raises the question of equality of access to hematopoietic stem cells transplant, especially in the Mediterranean zone, which has taken in many waves of immigration. The aim of our study is to address whether, in the Marseille CB Bank, CBU qualification rate is impaired by geographic origin. The study compared biological characteristics of 106 CBU disqualified for total nucleated cell (TNC) count (dCBU) and 136 qualified CBU in relation to registry enrichment and haplotype origin. A high proportion (>80%) of both dCBU and CBU had at least one non-European haplotype and enrich CB and UD registries to a higher extent than those with two European haplotypes (Pdiverse Mediterranean origins do not have an impact on the CBU qualification rate. Partnership with Mediterranean birth clinics with highly trained staff is a reasonable option to increase the HLA diversity of CB Bank inventories and to improve the representation of minorities.

Methods the research is based on the general dialectic method of cognition comparative historical formaljuridical methods as well as special and privatelegal methods of research. Results analysis of the main problems and collisions of administrative prejudgment in the Russian criminal law the doctrine and the practice of implementation of this institution can become the basis for legalization of the administrative prejudgment in the Russian criminal law and implementing it for the crimes stipulated in the Special part of the Russian Criminal Code if they are of low or middle gravity and committed intentionally those most often occurred. The article studies the institution of the administrative prejudgment in the Russian criminal law since 1922 until present. Various researchersrsquo opinions are given for and against returning of this institution. Taking into account the criminological indicators the authors express their own opinion on legalization of the administrative prejudgment. Scientific novelty having abandoned the formal approach to the institution of the administrative prejudgment both in the Russian criminal law and in the foreign laws the authors believe that the criminal personality should be the central factor of the administrative prejudgment legalization.

    TRIGA-LEU fuel is currently undergoing high power tests in the 30 MW Oak Ridge Reactor. These tests are being funded by the Department of Energy through the RERTR program [Reduced Enrichment Research and Test Reactor program administered by Argonne National Laboratory] and began in mid-December, 1979 on a 16-rod shrouded cluster. The fuel rods are 0.51 in. 0D, clad with 0.16 in. Incoloy and the fuel length is 22 in. It is planned to test the UZrH fuel with 45, 30 and 20 wt-% U (nominal 20% enriched), to burnup values of about 50% of the contained U-235 in the 45 wt-% rods and about 40% and 35% burnup in the 30 wt-%, and 20 wt-% U fuel. It will take about 2 years of irradiation to produce the desired burnup in the 45 wt-% U fuel. Currently being tested are six 45 wt-% U and five 30 wt-% U rods. The remaining 5 rods are stainless steel dummies which were necessary to meet an operational requirement of the ORR which limits the power generation in a fuel rod to a value which would not raise the coolant temperature above the saturation level. Maximum calculated fuel rod powers were 40 kW, which would produce a fuel temperature of about 650 deg. C. The measured temperatures are about 400 deg. C and 350 deg. C for the 45 and 30 wt-% U fuel, respectively. Flow and {delta}T measurements show the cluster power generation to be about 250 kW, or about 65% of the design value. Reasons for the lower than expected power are still being evaluated and a proposal has been submitted for rearrangement of the fuel rods within the cluster to raise the powers and temperatures in the TRIGA-LEU fuel rods.

  19. All quiet on the eastern front? Disruption scenarios of Russian natural gas supply to Europe

    International Nuclear Information System (INIS)

    Richter, Philipp M.; Holz, Franziska

    2015-01-01

    The 2014 Russian–Ukrainian crisis reignited European concerns about natural gas supply security recalling the experiences of 2006 and 2009. However, the European supply situation, regulation and infrastructure have changed, with better diversified import sources, EU member states being better connected and a common regulation on the security of supply has been introduced. Nevertheless, European dependency on natural gas remained high. This paper investigates different Russian natural gas export disruptions scenarios and analyses short- and long-term reactions in Europe. We use the Global Gas Model (GGM), a large-scale mixed complementarity representation of the natural gas sector with a high level of technical granularity with respect to storage and transportation infrastructure. While we find that most of the EU member states are not severely affected by Russian disruptions, some East European countries are very vulnerable. Prioritizing the removal of infrastructure bottlenecks is critical for securing a sufficient natural gas supply to all EU member states. - Highlights: • We analyze disruption scenarios of Russian natural gas exports to Europe. • Most EU countries are only weakly affected by a complete Russian supply disruption. • We find that Eastern Europe is vulnerable to Russian supply disruptions. • We identify infrastructure bottlenecks in the European natural gas network. • We find that the large EU LNG import capacity is not sufficiently connected

    The immaturity of strategic and conceptual documents in the sphere of sustainable development of the Russian economy had a negative impact on long-term strategic forecasting of its neo-industrialization. At the present stage, the problems of overcoming the mineral and raw material dependence, the negative structural shift of the Russian economy, the acceleration of the rates of economic growth, the reduction of technological gap from the developed countries become strategically in demand. The modern structure of the Russian economy, developed within the framework of the proposed market model, does not generate a sustainable type of development. It became obvious that in conditions of the market processes' entropy, without neo-industrial changes, the reconstruction of industry on a new convergence-technological basis and without increasing the share of high technology production the instability of macroeconomic system, the risks of environmental and economic security of Russia are growing. Therefore, today we need a transition from forming one industry development strategy to the national one that will take into account both the social and economic and environmental challenges facing Russia as a mineral resources extracting country.

    2017-01-01

    Full Text Available Russian gas export liberalization has been discussed throughout the post-Soviet period. Recently, the number of Gazprom’s export monopoly advocates has been diminishing as a result of dramatic changes in both European and Russian gas markets, which are: increasing international trade in liquefied natural gas; the EU movement from long-term contracts to the commodity markets and hub pricing; substantially increased share of the non-Gazprom gas suppliers at the Russian domestic market. Although there is a potential risk of price decrease in the EU gas market in the case of the Gazprom export monopoly abolition, the benefits of the Russian gas export liberalization would be greater than losses. The gas resource base and the cost of pipeline gas production would allow Russia to improve its positions in the world market.

    Full Text Available Author of the article gives an explanation of Russian economy slowing down from 4 quarter 2011 till 3 quarter 2013. According to author reasoning the main problem of Russian economy throughout this period of time was growth of real interest rates. The growth of real interest rate is determined by monetary policy, conducted by Central Bank. The main priority of CB is fight against inflation, which is waged by liquidity shrinkage. The bottom-line is fall of inflation and interest rates growth (including lending rate. Real interest rates are growing drastically. In certain branches of economy (for instance manufacturing real interest rates growth amounted to 10 and more percentage points.CB calls this policy inflation targeting. Besides fight against inflation floating ruble is important feature of this policy. The author made a conclusion that floating ruble when hydrocarbons prices are at historical maximum level is the worst recipe for Russian economy which is strongly dependent from hydrocarbons export revenue. The author compares Russian monetary and budget policy with monetary and budget policy of other countries with distorted export structure, for example Saudi Arabia and Norway. The author came to conclusion that Russian monetary and budget policy combination is unique among countries dependent from hydrocarbons export revenues. Result of this monetary and budget policy is vulnerability toward external shocks, tradable sectors noncompetitiveness, close to zero growth rate of economy and deterioration all branches of Russian economy. Zero net of payment balance while high oil price is economic nonsense. DOI: http://dx.doi.org/10.12731/2218-7405-2014-2-7

    2015-06-01

    Full Text Available The researchers often overlook the relationships between Russian and Nordic investment capital; and even less attention is paid to studying the competition between the two. Yet this subject can be of particular relevance to the areas that are geographically, historically and culturally close to both Russia and the Nordic countries. Thus, the aim of this article is to understand how the competition between Russian and Nordic capital investment is played out in the Baltic States. The study discusses the principles of Russian and Nordic investment in the Baltic, and suggests ways to regulate these relations. To this end, we compare the investment conditions created in the Baltic States for both Russian and Nordic investors. The analysis shows that most of the Baltic market is controlled by the Nordic capital, which blocks the arrival of Russian investment to the Baltic States. With a nod to a number of previous studies, the authors of this article suggest some adjustments to the theory of foreign direct investment. The study will be also of practical interest to those Russian investors who are seeking entry points to the Baltic markets.

    In 1992, in an effort to curtail use of Highly Enriched Uranium (HEU), hoping to alleviate nuclear security concerns, United States passed the Schumer amendment to the Energy Policy Act. This legislation conditioned U.S. export of HEU to foreign companies, understanding that these companies would switch as soon as possible to Lowly Enriched Uranium (LEU). This paper describes 99 Mo production flow chart, characteristics of process cells, shielding, systems of manipulation at distance, cell ventilation system and the method for personal dose monitoring. Production evolution for the span of years 1998 to 2007 is given by indicators, keeping in mind enrichment proportion change. Evolution shown on the indicators is directly related to the application of Safety Culture concepts adopted by personnel. (author)

    The CNEA (Comision Nacional de Energia Atomica - Argentina) operated two facilities at the Ezeiza Atomic Center which supply purified enriched uranium employed in the production of nuclear fuels. At one of those facilities, the Triple Height Laboratory scraps from the production of MTR type fuel elements (mainly out of specification U 3 O 8 plates or powder) are purified to nuclear grade. The purification is accomplished by a solvent extraction process. The other facility, the Enriched Uranium Laboratory produces 90% enriched uranium metal to be used in Mo 99 production (originally the uranium was used for the manufacture of MTR fuel elements made of aluminium-uranium alloy). This laboratory also provided metallic uranium with a lower enrichment (20%) for a first uranium-silicon testing fuel element, and in the near future it is going to recommence 20% enriched uranium related activities in order to provide the metal for the silicon-based fuel elements production (according to the policy of enrichment reduction for MTR reactors).

    Full Text Available Climate change in the Russian Arctic is more pronounced than in any other part of the country. Between 1955 and 2000, the annual average air temperature in the Russian North increased by 1.2°C. During the same period, the mean temperature of upper layer of permafrost increased by 3°C. Climate change in Russian Arctic increases the risks of the emergence of zoonotic infectious diseases. This review presents data on morbidity rates among people, domestic animals and wildlife in the Russian Arctic, focusing on the potential climate related emergence of such diseases as tick-borne encephalitis, tularemia, brucellosis, leptospirosis, rabies, and anthrax.

  20. Nuclear energy and society: Russian dimension

    Nuclear weapons and crisis of confidence resulting from severe accidents have both formed the attitude towards nuclear issues in the Russian minds. The current status of relations between nuclear energy and the public is still close to this politicization of nuclear energy and to the constant irrational fear of radiations. The 3 basic antinuclear arguments usually mentioned are proliferation risk, wastes and accidents. For proliferation risk it is easy to understand that a complete nuclear power phase-out would not prevent the spreading of nuclear weapons because uranium and centrifuges would still exist. For the Russian society, the issue of radioactive wastes is popular these days because the Russian parliament is considering a bill about it. The issue of radioactive wastes seems to be economically and technically solvable. The main problem is nuclear accidents. In Russia this issue is very touchy: we still remember zero-radiation events, which, when happened not very long ago, have aroused panics in whole regions. It is hard to change the idea, well spread in Russian minds that the authorities are always trying to understate the scale of negative events. Nevertheless, some recent polls show that the positive trend in the attitude towards nuclear energy is obvious as it is in most part of the world. (A.C.)
