    The results of CMP seismic data acquisition along regional deep profiles that cross large tectonic elements in the east of the East European Platform are considered. It has been established that the Zhiguli-Pugachev Arch and the Stavropol Depression (southern part of the Melekess Basin), as well as the Volga-Kama Anteclise and Pericaspian Syneclise, conjugate along reverse-thrust faults extending to the lower crust and Moho discontinuity. The position of the southeastern reverse-thrust boundary of the South Tatar Arch has been substantially specified in plan view and illustrated by seismic sections. Based on the results obtained, it is suggested that reverse-thrust faults of different orders are widespread in petroleum provinces in the east of the East European Platform, and this suggestion should be used in geological exploration. The CMP seismic data acquisition is efficient in studying the junction zones of large tectonic elements. It also provides insights into the deep structure of the Earth's crust and its relationship to the structure and petroleum potential of the sedimentary cover and localization of oilfields. It is expedient to reprocess and integrate earlier seismic data in order to compile tectonic (tectonodynamic) regional maps on a new methodical basis.

    This study presents new data on the manifestations of pre-Mesozoic intraplate mafic magmatism beneath the Vendian-Paleozoic and Mesozoic-Cenozoic sedimentary cover of the Russian Plate. The data were obtained from interpretation of high-resolution aeromagnetic and gravity surveys performed over the past two decades. Buried volcanic structures, dike belts, trap fields, and thick mafic intrusions are described. The four phases of magmatism distinguished in this study (Riphean, Vendian, Devonian, and Late Paleozoic) are temporally correlated with the main rifting stages that took place in the East European Platform.

    The group of quakes, which are caused by fast freezing of water-saturated soils or rocks at abrupt drop of winter temperatures often occurring in the middle and high latitudes of Eurasia, is considered. The review of little-known literature is given; the statistical data on the distribution of earthquakes in seasons and the time of day in various regions of Eurasia are presented. Special attention is paid to the East European Platform; using the data for this platform, with thorough consideration of reference quakes along with the weather conditions, the signs of a specific class of nontectonic seismic events are determined. The question concerning the necessity of the frost quakes’ discrimination in compilation of tectonic earthquake catalogues in certain regions is stated.

    A measurement system for location seismic events in the Central Part of East European Platform is situated within the Mikhnevo Geophysical Observatory of the RAS Institute of Geospheres Dynamics and consists of 12 seismic stations. One vertical station is located in the center of the group in a shaft tunnel. The other stations are located on the periphery in three concentric circles and are almost equally spaced with regard to the terrain to ensure full azimuth coverage to the maximum extent possible. The unique array identifies events with a magnitude up to 3 at the distances until 1000 km within the Central Part of East European platform. Most of the events recorded by the Mikhnevo array at a distance of 60-500 km are man-made events represented by explosions in quarries during the development of mineral deposits. Long-term seismic records of explosions in quarries have been processed for the period from 2004 to 2014 to generate a database containing standard waveforms for each quarry. Some events of unknown origin appear in the records for this period; these do not correspond to the identified seismic forms for explosions in known quarries. Epicenter coordinates for these events do not match the coordinates of the known quarries. A cosmotectonic map of the Central Part of East European Platform was compiled during the studies using the LESSA software package (Lineament Extraction and Stripe Statistical Analysis) and data on the deep crustal structure, which made it possible to define the morphostructural plan and evaluate the geodynamic conditions in the area. The deep basement structure through the sedimentary cover is expressed in the surface texture of the area under study. The region's neotectonics is closely related to the history of deep structures, in particular, aulacogens extending in different directions, which may show in the contemporary morphostructural plan, mainly as inversion and partially inherited forms.

  5. Geochemistry of mantle metasomatism related to formation of kimberlites in the northern East European Platform

    The geochemistry of mantle metasomatism related to the formation of kimberlites and allied rocks in the northern East European Platform (EEP) is considered with allowance for chemical systematics and geodynamic position. The Paleoproterozoic kimberlites of Kimozero, Mesoproterozoic orangeites of Karelia, Neoproterozoic kimberlites of Finland, and Devonian kimberlites of the Arkhangel'sk diamond province (ADP) are the objects of this research. Kimberlites from the EEP are characterized by wide variations in contents of rock-forming oxides and trace elements caused by secondary alteration, belonging to different lithofacies and specific sources. The diversity of kimberlites from the EEP is explained by the interaction of asthenospheric protokimberlitic melt with depleted or metasomatically enriched lithospheric mantle. A (Zr/Sm) n -Cr/Ni diagram has been proposed to identify specific attributes of mantle metasomatism. Comparison of the geodynamic setting of kimberlite formation in the EEP with the revealed geochemical features of mantle metasomatism shows that kimberlites having sources with the participation of MARID-type meta-somatic assemblages were formed under conditions of changing supercontinental cycles, when the breakdown of large supercontinent coincided in time with the initial stage of assembly of a new supercontinent. This is characteristic of the Kimozero kimberlites, orangeites of Karelia, and kimberlites from the ADP. Kimberlites of Finland were formed under geodynamic conditions characterized by supercontinent breakdown coeval with abundant within-plate mafic magmatism. These kimberlites bear geochemical features inherent to an asthenospheric source. The economic Devonian diamond-bearing kimberlites from the ADP display a subordinate role of the metasomatic lithospheric as a component of their source against the background of a significant interaction of melted asthenospheric material with the depleted lithospheric mantle.

  6. Lithospheric structure, composition, and thermal regime of the East European Craton: Implications for the subsidence of the Russian platform

    A new mechanism for Paleozoic subsidence of the Russian, or East European, platform is suggested, since a model of lithosphere tilting during the Uralian subduction does not explain the post-Uralian sedimentation record. Alternatively, I propose that the Proterozoic and Paleozoic rifting (when a platform-scale Central Russia rift system and a set of Paleozoic rifts were formed) modified the structure and composition of cratonic lithosphere, and these tectono-magmatic events are responsible for the post-Uralian subsidence of the Russian platform. To support this hypothesis, (a) the thermal regime and the thickness of the lithosphere are analyzed, and (b) lithospheric density variations of non-thermal origin are calculated from free-board constraints. The results indicate that Proterozoic and Paleozoic rifting had different effects on the lithospheric structure and composition. (1) Proterozoic rifting is not reflected in the present thermal regime and did not cause significant lithosphere thinning (most of the Russian platform has lithospheric thickness of 150-180 km and the lithosphere of the NE Baltic Shield is 250-300 km thick). Paleozoic rifting resulted in pronounced lithospheric thinning (to 120-140 km) in the southern parts of the Russian platform. (2) Lithospheric density anomalies suggest that Proterozoic-Paleozoic rifting played an important role in the platform subsidence. The lithospheric mantle of the Archean-early Proterozoic part of the Baltic Shield is ??? 1.4 ?? 0.2% less dense than the typical Phanerozoic upper mantle. However, the density deficit in the subcrustal lithosphere of most of the Russian platform is only about (0.4-0.8) ?? 0.2% and decreases southwards to ???0%. Increased densities (likely associated with low depletion values) in the Russian platform suggest strong metasomatism of the cratonic lithosphere during rifting events, which led to its subsidence. It is proposed that only the lower part of the cratonic lithosphere was

    Velocity model of mantle beneath the south-western margin of the East-European platform demonstrates its heterogeneous structure. Accordingly to the crustal structures above mantle heterogeneities were defined as: Volyno-Podolian, Ros-Bug, Ingulo-Middlednieper, Periasov, Volyno-Podolian plate, Peridnister, Peri-Blacksea, Chernigov, Dnieper, Donetsk, Eastern-Blacksea, Crimea, Western-Blacksea. These blocks are defined as regions differing in the depth of the bottom of the velocity layers that characterize velocity structure of the mantle and in the velocity characteristics of these layers. Layer boundaries are defined as intersection with 1-d reference model. Areas with residuals >0.0 km/s are considered as high-velocity while areas with residuals <0.0 km/s are defined as low-velocity. There is a spatial correlation between boundaries of mantle blocks and location of oil-gas deposits and basic-ultrabasic magmatism. Some of the mantle blocks (Peri-Blacksea, Eastern-Blacksea, Crimea, Western-Blacksea, Periasov, Volyno-Podolian plate, Peridnister) that situated beneath margin of the platform and others (Chernigov, Dnieper, Donetsk) that situated beneath the Dnieper-Donetsk depression display spatial correlation with crust-seated oil-gas provinces - Crimean, Volyno-Podolian, Pericarpathian, and Dnieper-Donetsk, correspondingly. Oil-gas field have a propensity for boundaries of mentioned above mantle blocks. Those mantle blocks (Volyno-Podolian, Ros-Bug, Ingulo-Middlednieper, Periasov) that located under the Ukrainian shield display spatial correlation with basic-ultrabasic magmatism that confined to the blocks boundaries. Age of this magmatism varies from Paleoproterozoic to Neoproterozoic.

    The complex zone between the Moesian and East European platforms to the south and east and the Southern Europe continental units were amalgamated in the last 20 million years in an intricate dynamics of what was thought to be the eastern component of the Alpine Tethys. By seismic tomography and attenuation studies, a high velocity body extended from the near surface to deeper levels than 300 km was pointed out as having a very complex geometry which suggests a very active three dimensional evolution. Most of the frequent, persistent and clustered seismic events from this contact area known as Vrancea Seismogenic Zone are located into this high velocity body. The origin of this seismicity is highly controversial. Among most of the accepted assumptions on its origins, two look like most robust: (a) the recent studies consider the subduction of the Tehys oceanic lithosphere, and (b) delamination of a portion of the East European / Moesian continental mantle after the oceanic lithosphere subduction ended sometimes in the mid-Miocene. The delamination zone was probably a near-horizontal mid-lithospheric interface dripping down into the mantle. Towards the internal part of the Bend Zone, the volcanic activity, dominant in the Neogene time, ceased some 400,000 years ago but there are evidences that the last stages of the alkali-basaltic volcanic activity has post-volcanic effects even at present. We integrate satellite geodesy results with various seismological studies in order to explain the very small values of the present-day horizontal component of the velocity field, almost at the edge of technological detectability. The vectors have a very peculiar distribution which we interpret as supporting the idea of the mantle flow around the high seismic velocity body detected via seismological investigations. We estimate an anti-clockwise deep rotation flow around the lithospheric "slab" which is seated adjacent to the astensosphere advancing towards the surface, having

    A new 240-km long, deep seismic reflection profile (POLCRUST-01) was recently acquired in SE Poland crossing the East European Platform (EEP) margin south-east of the North-German-Polish Caledonides (NGPC). Here we document geophysical field work and subsequent data processing and modeling. Results obtained from reflection seismic data are augmented by results of the first-arrival tomography applied to co-located extended-offset refraction data, as well as potential field modeling and comparison with the available wide-angle reflection/refraction data. Our preferred model of the crustal structure, derived by integrating seismic, potential field and geological data, is composed of crustal blocks (terranes) separated by nearly-vertical faults. These are: (I) intact part of the EEP; (II) Łysogóry Terrane; (III) Małopolska Terrane; and (IV) Carpathian Mts. with their basement. Reflective lower crust of the EEP can be an inherited feature of crustal extension (rifting) or compressional tectonics acting at the cratonic margin. The Teisseyre-Tornquist Zone (TTZ) is depicted as a Caledonian transcurrent accretion zone corresponding with the near-vertical Tomaszów Fault, bounding the Łysogóry Terrane to the east. The crust of the Łysogóry Terrane suggests EEP affinity, although its middle/lower crust thickness is highly reduced. The Małopolska Terrane seems to be internally subdivided into blocks of different magnetic properties of the lower crust. The Carpathian frontal thrust is associated with a change in the rock properties in the deep basement (an unknown crustal block?) which is not visible in seismic data alone. The interpreted structure of the Caledonian terranes and their tectonic boundaries favors a transcurrent style of a crustal accretion along the central and SE Polish segments of the TTZ, implying a very complex nature of the Caledonian accretionary belt of Central Europe: from an array of terranes displaced along the TTZ to an accretionary wedge of

    2009-05-01

    We present analysis of lateral variations of density in the upper mantle in the area of contact of the precambrian East European Craton (EEC) and the Palaeozoic Platform (PP) in Poland, obtained by analysis of the gravimetric geoid undulations. A precise 3-D density model of the crust in the study area down to a depth of 50 km, discussed in the first part of this paper (Majdański et al., in press) did not explain all features of the observed geoid. This suggests that these features can be due to density inhomogeneities in the upper mantle. To estimate them, we performed inversion of a residual between the observed geoid and undulations caused by the 3-D density distribution in the crust. Basing on the assumption of local isostatic compensation and Pratt-Hayford isostasy model, the density distribution in the upper mantle was parametrized as a 40-km-thick layer located above the assumed compensation depth of 140 km and subdivided into irregular blocks. The boundaries of the blocks were defined according to boundaries of major tectonic units in the study area and position and shape of the most pronounced anomalies in the residual geoid. A series of sensitivity tests calculated for such density heterogeneities in the upper mantle showed that they can produce geoid undulations of the order of several metres. The density values in each unit were taken as model parameters for the inversion procedure, and inverse problem was solved using global optimization with constraints. The density variations in the upper mantle in the final model correlate well with the surface heat flow. This suggests that these variations can be due to diversity in mantle temperature. The Trans-European Suture Zone (TESZ), which is a major suture separating the EEC from the PP, is not observed as a distinct unit in the mantle. Instead, our study suggests continuation of the lithosphere of the EEC beneath the PP and confirms subdivision of the TESZ into terranes with distinctly different evolution

    In the south-eastern East European platform and Urals, as well as the young Scythyan platform, the Late Alpine collision deformations are widely spread. First of all, these are crumbled aulacogen covers (the Azov Sea, Dnieper-Donets, and Pachelma aulacogens). In some places the covers were dislocated conformably with platform basements but commonly they were partly detached from it with formation of inversion foldbelts (such as the Donets coal basin in the Alpine stage, Saratov and Kerensk-Chembar dislocations). Basements of some anteclises (the Voronezh, Tokmovo, and Volga-Urals ones) dividing the aulacogens were also involved into deformations. There the greatest upthrusting of basement onto cover can be observed (e.g., the Zhigouli upthrust). In general the thrusting and folding occurred during the Early Miocene-Quaternary, with its periodicity strictly corresponding to that of the Late Alpine tectonic phases in the Greater Caucasus: Early Miocene (the H. Stille,s Styrian phase), terminal Miocene-initial Pliocene (the Attic and Rhodanian phases), Eo-Pleistocene (the Valachian phase). Beside the synchronous occurrences, there are some other evidences of relation of intraplate deformations to the Arabia-Eurasa collision in its Caucasian region: (i) sublatitudinal (up to WNW-ESE strike) orientation of the intraplate upthrusts and folds, (ii) wide distribution of structurally manifested strike-slip zones as well as similarity in orientation and location between the right and left strike-slips considered with those of the Greater Caucasus: domains of the formers are built up to the north the domains of the latters, (iii) directed southward increasing basement involvement into the neotectonic deformations. For example, in the Donets-Azov region a basement neotectonic megafold was imposed not only onto Donets Herzinian foldbelt but also on the Precambrian basement of the Rostov high of the Ukrainian shield. To some extent, this megafold resembles a northern wing of the

    Although first paleomagnetic investigations of the Ordovician rocks at the Leningrad area were begun more than 40 years ago (A.N. Khramov, 1958), number of palepmagnetic data for the Ordovician pole of the East-European platform (EEP)is limited enough till now. Exept paleomagnetic poles obtained by Smethurst et al. (1998), all others paleomagnetic results based on ivestigations of Swedish Ordovician limestones (Torsvik and Trench, 1991; Trench and Torsvik, 1991; Claesson, 1998; Torsvik et al., 2000; Perroud et al., 1992). These data suggest that northwest margin of East-European platform located at 40S at Llanvirn time. However paleomagnetic data for Lower Ordovician red-colored sandstones and aleurolites (Didenko, Lubnina, 1998) testify for more low-latitude location of the EEP at that time. For solution of this difficulty and also for increasing of paleomagnetic database we sampled carbonaceous sections of Volkhov and Kunda stages (Llanvirn) not far from village Shirokovo and in Lomashka river valley. The other important task of our researches was receive new magnitostratigraphy information about polarity of Llanvirn geomagnetic field. Thermal demagnetization of these rocks yield two monopolar components.The first one component A is allocated as characteristic, has unblocking temperatures about 400-450° and is typical for low-magnetic samples (magnetization less than 1-2.10-4 ). Another - component B removed maximum at 500-560C and is typical for high-magnetic samples (magnetization more than 2-3.10-4). Mean direction of component B (D= 36.8; I = 58.3; N = 33; K = 31.8; alfa95 = 4.5) is close to the direction of Mezozic magnetization reversal (Smethurst et al., 1998). Sometimes components A and B occur together and component B is less stability. However there are also took place return cases. Mean direction of components A (D = 156.4; I = 38.8; N = 29; K = 31.8; alfa95 = 11.3) is close to Ordovician direction (Torsvik and Trench, 1991; Trench and Torsvik, 1991

    As the largest scientific organisation world-wide exclusively dedicated to general thoracic surgery (GTS), the European Society of Thoracic Surgeons (ESTS) recognized that one of its priorities is education. The educational platform designed ESTS addresses not only trainees, but also confirmed thoracic surgeons. The two main aims are (I) to prepare trainees to graduation and to the certification by the European Board of Thoracic Surgery and (II) to offer opportunities for continuous medical education in the perspective of life-long learning and continuous professional development to certified thoracic surgeons. It is likely that recertification will become an obligation during the coming decade. At its inception, the platform differentiated two different events. A 6-day course emphasizing on theoretic knowledge was created in Antalya in 2007. The same year, a 2-day school oriented to practical issues with hands-on in the animal lab was launched in Antalya. These two teaching tracks need further development. In the knowledge track, we intend to organize highly specialized 2-day courses to deepen insight into theoretical questions. The skill track will be implemented by specialized courses for high technology such as tracheal surgery, ECMO, robotics or chest wall reconstruction. In order to promote tomorrows' leadership, we created an academic competence track giving an insight into medical communication, methodology and management. We also had to respond to an increasing demand from the Russian speaking countries, where colleagues may face problems to attend western meetings, and where the language bareer may be a major impediment. We initiated a Russian school with three events yearly in 2012. Contemporary teaching must be completed with an e-learning platform, which is currently under development.

    On the occasion of the 50th anniversary of the foundation of the "German Society of Anaesthesiology" (DGA)--later called "German Society of Anaesthesiology and Intensive Care Medicine" (DGAI)--which was founded on 10 April 1953, and in memory of the foundation of the "Section of Anaesthesiology", which was founded in East-Berlin ten years later on 25 October 1963 and later called "Society of Anaesthesiology and Intensive Therapy of the GDR" (GAIT), the development of relations between German anaesthetists and anaesthesiological societies in East Europe are described. The limited economic base of the medical-technical and pharmaceutical industries, a chronic lack of hard currencies and economic and political restrictions on travel activities by East German and East European anaesthetists to West European countries resulted in improved contacts between East German and East European anaesthesiological societies. This, in turn, led to the holding of "International Anaesthesiological Congresses" of the so-called socialist countries and "Bilateral Symposia of the Anaesthesiological Societies of Czechoslovakia and the GDR" and also bilateral meetings of nurses of anaesthesiology and intensive therapy from both countries. These congresses and in particular the "3rd European Congress of Anaesthesiology", which was hosted by the "Czechoslovak Society of Anaesthesiology and Resuscitation" in Prague in 1970, were of high value for the further development of anaesthesiology in these countries. Furthermore, congresses held in East Europe but outside the GDR, were especially important for meetings between East German anaesthetists and their West German colleagues, who regularly took part in these congresses as invited speakers, because West German anaesthetists were not allowed to participate in East German anaesthesia congresses, on the one hand, and East Germans were not allowed to attend West German anaesthesia congresses, on the other.

    To study the male and female lineages of East Asian and European humans, we have sequenced 25 short tandem repeat markers on 453 Y-chromosomes and collected sequences of 72 complete mitochondrial genomes to construct independent phylogenetic trees for male and female lineages. The results indicate that East Asian individuals fall into two clades, one that includes East Asian individuals only and a second that contains East Asian and European individuals. Surprisingly, the European individuals did not form an independent clade, but branched within in the East Asians. We then estimated the divergence time of the root of the European clade as ∼41,000 years ago. These data indicate that, contrary to traditional views, Europeans diverged from East Asians around that time. We also address the origin of the Ainu lineage in northern Japan. PMID:24589501

    New finds and revision of available collections of nonmarine bivalves provided grounds for development of a zonal scale for terrestrial sequences of the Permian System based on species belonging to the genus Palaeomutela Amalitzky, 1891, which are characterized by regular changes in the structure of the shell hinge. The scale includes two parallel zonal successions that are based on the stratigraphic distribution and evolutionary trends of two morphological lineages of the genus. The zonal succession based on development of the P. umbonata group (dwellers of mobile waters and silty-psammitic substrates) includes 11 range zones: stegocephalum, ovatiformis, umbonata, quadriangularis, krotowi, wohrmani, numerosa, ulemensis, keyserlingi, curiosa, golubevi. The zonal succession based on development of the P. castor group (dwellers of calm waters and silty-pelitic substrates) includes eight range zones: larae, castor, olgae, doratioformis, marposadica, fischeri, obunca, amalitzkyi. The proposed zonal units are correlated with scales based on ostracod, fish, and tetrapod fossils. New species Palaeomutela golubevi sp. nov. and P. amalitzkyi sp. nov. are described with the extended diagnosis of the genus Palaeomutela.

    Eymar, P.; Peyrin, Y.; Cougnet, C.; Brudieu, P.; Dutto, P.

    In order to get a better knowledge of servicing problems and scenarii of the future European In Orbit Infrastructure, CNES (French Space Agency) decided to fund two separate servicing analysis, respectively conducted by Aérospatiale and MATRA. Aérospatiale work deals with several possible manned stations, taking into account a previous study, while MATRA work deals with polar platform aspects. The first part (Servicing of manned Space Stations) deals with a possible optimization of the roles to be played both by the future Ariane 5 launcher in automatic mode and by the Hermes Spaceplane for the servicing of some future manned space stations: the Columbus pressurized module on the U.S. Space Station, a non-evolutive one-module autonomous station and a multi-module one with a growth capability. After having identified the potential cargoes required for the maintenance and servicing of these stations (analysis of payloads, maintenance ORUs, consumales, crew exchange) and the possible frequencies of such a servicing, it is intended to show how it can be achieved through European means. Established scenarii make use of the Ariane 5 launcher combined either with the Hermes vehicle or with an automated payload. Solutions using payload carriers and/or logistic modules are examined, and possible impacts on stations and/or vehicles are identified further, following investigations on orbital transfer operations. The second part (Servicing of polar platforms) describes the possible scenarii of in-orbit implementation and servicing of a polar platform (number of Ariane 5 launches, modes of transfer, type of service vehicles, servicing orbit, …). This part is focused on the in-orbit operation to exchange on ORU (Orbital Replaceable Unit), once both platform and Hermes (or other servicing vehicle) are attached. After a review of the main tasks to be performed and the possible means to be used as manipulator or EVA, the paper describes the scenario (extraction of an ORU

    Polar research and in particular the properties of northern and southern high latitude oceans are currently a subject of intense scientific debate and investigations, because they are subject to rapid and dramatic climatic variations. Polar regions react more rapidly and intensively to global change than other regions of the earth. A shrinking of the Arctic sea-ice cover, potentially leading to an opening of sea passages to the north of North America and Eurasia, on the long to a "blue" Arctic Ocean would additionally have a strong impact on transport, commerce and tourism bearing potential risk for humans and complex ecosystems in the future. In spite of their critical role processes and feedbacks, especially in winter but not exclusively, are virtually unknown: The Arctic Ocean for example, it is the only basin of the world's oceans that has essentially not been sampled by the drill ships of the Deep-Sea Drilling Project (DSDP) or the Ocean Drilling Program (ODP) and its long-term environmental history and tectonic structure is therefore poorly known. Exceptions are the ODP Leg 151 and the more recent very successful ACEX-expedition of the Integrated Ocean Drilling Program (IODP) in 2004. To help to address the most pressing questions regarding climate change and related processes, a Pan-European initiative in the field of Earth system science has been put in place: AURORA BOREALIS is the largest environmental research infrastructure on the ESFRI roadmap of the European Community. AURORA BOREALIS is a very powerful research icebreaker, which will enable year-round operations in the Arctic and the Antarctic as well as in the adjacent ocean basins. Equipped with its drilling rig, the vessel is also capable to explore the presently completely unknown Arctic deep-sea floor. Last but not least, the ship is a floating observatory and mobile monitoring platform that permits to measure on a long-term basis comprehensive time series in all research fields relevant to

    We present a modeling study of the long-range transport of pollution from Europe, showing that European emissions regularly elevate surface ozone by as much as 20 ppbv in summer in northern Africa and the Near East. European emissions cause 50-150 additional violations per year (i.e. above those that would occur without European pollution) of the European health standard for ozone (8-h average greater than 120 micrograms per cubic meters or approximately 60 ppbv) in northern Africa and the Near East. We estimate that European ozone pollution is responsible for 50 000 premature mortalities globally each year, of which the majority occurs outside of Europe itself, including 37% (19 000) in northern Africa and the Near East. Much of the pollution from Europe is exported southward at low altitudes in summer to the Mediterranean Sea, northern Africa and the Near East, regions with favorable photochemical environments for ozone production. Our results suggest that assessments of the human health benefits of reducing ozone precursor emissions in Europe should include effects outside of Europe, and that comprehensive planning to improve air quality in northern Africa and the Near East likely needs to address European emissions.

    Historical records indicate that extensive cultural, commercial and technological interaction occurred between European and Asian populations. What have been the biological consequences of these contacts in terms of gene flow? We systematically estimated gene flow between Eurasian groups using genome-wide polymorphisms from 34 populations representing Europeans, East Asians, and Central/South Asians. We identified recent gene flow between Europeans and Asians in most populations we studied, including East Asians and Northwestern Europeans, which are normally considered to be non-admixed populations. In addition we quantitatively estimated the extent of this gene flow using two statistical approaches, and dated admixture events based on admixture linkage disequilibrium. Our results indicate that most genetic admixtures occurred between 2,400 and 310 years ago and show the admixture proportions to be highly correlated with geographic locations, with the highest admixture proportions observed in Central Asia and the lowest in East Asia and Northwestern Europe. Interestingly, we observed a North-to-South decline of European gene flow in East Asians, suggesting a northern path of European gene flow diffusing into East Asian populations. Our findings contribute to an improved understanding of the history of human migration and the evolutionary mechanisms that have shaped the genetic structure of populations in Eurasia. PMID:25833680

    The Trans-European Suture Zone (TESZ) manifests a broad transition between the Precambrian and Phanerozoic Europe. To contribute to better understanding the upper mantle structure, we analyse isotropic velocity variations by means of standard teleseismic tomography as well as we analyse anisotropic parameters of teleseismic body waves. The velocity perturbations in the tomographic model down to 600 km indicate the Phanerozoic part of Europe thrust over the Precambrian East European Craton (EEC). Depth of the lithosphere-asthenosphere boundary (LAB) - modelled as a transition between fossil anisotropy in the mantle lithosphere and anisotropy due to present-day flow in the underlying asthenosphere - increases to ~250 km toward the EEC. For anisotropy study, we examine lateral variations of directional terms of relative P-wave travel-time deviations from about 100 teleseismic events, selected to provide good azimuthal coverage, and evaluate shear-wave splitting parameters from about 20 events recorded during passive seismic experiment PASSEQ (2006-2008). We model in 3D large-scale olivine fabrics of mantle lithosphere domains on a transect from the eastern limit of the Bohemian Massif (BM) through the Polish Paleozoic Platform towards the Teisseyre-Tornquist Zone (TTZ) - the NE limit of the TESZ - to the East European Craton (EEC). Variations of anisotropic signal around the central part of the TESZ are surprisingly moderate. There is no distinct change of the P-residual pattern and shear-wave splitting parameters across the surface trace of the TTZ. The most distinct change of the anisotropic signal occurs at the northern boundary of the BM. Week changes of the mantle lithosphere structure across the TESZ suggest, in accord with results from P-wave tomography, a south-westward continuation of the EEC beneath this broad and diffuse paleoplate boundary. Inferences from seismic tomography as well as seismic anisotropy indicate that this laterally heterogeneous pervasive

    Passive experiment "13 BB star" is dedicated to study deep structure of the Earth's interior in the marginal zone of the East European Craton in northern Poland. The seismic network consists of 13 broadband stations on the area of c. 120 km in diameter. The network is located in the area well recognized from the point of view velocities of sedimentary cover and crustal structure. Good records obtained since summer 2013, and expected during next 1.5 years long recording campaign, should yield images of detailed structure of the lithosphere-asthenosphere boundary (LAB), „410", "?520", and „660" km discontinuities, as well as mantle-core boundary and inner core. The LAB is investigated recently very effectively, mostly using seismic methods because their deep penetration and relatively good resolution. The nature of LAB is still debated, particularly under "cold" Precambrian shields and platforms. We show examples of local and teleseismic records, array transfer function of "13 BB star" network and preliminary noise analysis.

  13. Window into the Caledonian orogen: Structure of the crust beneath the East Shetland platform, United Kingdom

    Reprocessing and interpretation of commercial and deep seismic reflection data across the East Shetland platform and its North Sea margin provide a new view of crustal subbasement structure beneath a poorly known region of the British Caledonian orogen. The East Shetland platform, east of the Great Glen strike-slip fault system, is one of the few areas of the offshore British Caledonides that remained relatively insulated from the Mesozoic and later rifting that involved much of the area around the British Isles, thus providing an "acoustic window" into the deep structure of the orogen. Interpretation of the reflection data suggests that the crust beneath the platform retains a significant amount of its original Caledonian and older architecture. The upper to middle crust is typically poorly reflective except for individual prominent dipping reflectors with complex orientations that decrease in dip with depth and merge with a lower crustal layer of high reflectivity. The three-dimensional structural orientation of the reflectors beneath the East Shetland platform is at variance with Caledonian reflector trends observed elsewhere in the Caledonian orogen (e.g., north of the Scottish mainland), emphasizing the unique tectonic character of this part of the orogen. Upper to middle crustal reflectors are interpreted as Caledonian or older thrust surfaces that were possibly reactivated by Devonian extension associated with post-Caledonian orogenic collapse. The appearance of two levels of uneven and diffractive (i.e., corrugated) reflectivity in the lower crust, best developed on east-west-oriented profiles, is characteristic of the East Shetland platform. However, a north-south-oriented profile reveals an interpreted south-vergent folded and imbricated thrust structure in the lower crust that appears to be tied to the two levels of corrugated reflectivity on the east-west profiles. A thrust-belt origin for lower crustal reflectivity would explain its corrugated

    The Health-e-Child (HeC) project [1], [2] is an EC Framework Programme 6 Integrated Project that aims to develop a grid-based integrated healthcare platform for paediatrics. Using this platform biomedical informaticians will integrate heterogeneous data and perform epidemiological studies across Europe. The resulting Grid enabled biomedical information platform will be supported by robust search, optimization and matching techniques for information collected in hospitals across Europe. In particular, paediatricians will be provided with decision support, knowledge discovery and disease modelling applications that will access data in hospitals in the UK, Italy and France, integrated via the Grid. For economy of scale, reusability, extensibility, and maintainability, HeC is being developed on top of an EGEE/gLite [3] based infrastructure that provides all the common data and computation management services required by the applications. This paper discusses some of the major challenges in bio-medical data integration and indicates how these will be resolved in the HeC system. HeC is presented as an example of how computer science (and, in particular Grid infrastructures) originating from high energy physics can be adapted for use by biomedical informaticians to deliver tangible real-world benefits.

    The Mesozoïc Egyptian margin is the south margin of a remnant of the Neo-Tethys Ocean, at the African northern plate boundary. East Mediterranean basin developed during the late Triassic-Early Jurassic rifting with a NW-SE opening direction (Frizon de Lamotte et al., 2011). During Mesozoïc, Egypt margin was a transform margin with a NW-SE orientation of transform faults. In the Eastern Mediterranean basin, Mesozoïc margins are characterized by mixed carbonate-siliciclastics platforms where subsidence and eustacy are the main parameters controlling the facies distribution and geometries of the platform-to-basin transition. Geometries and facies on the platform-slope-basin system, today well constrained on the Levant area, where still poorly known on the Egyptian margin. Geometries and stratigraphic architecture of the Egyptian margin are revealed, thanks to a regional seismic and well data-base provided by an industrial-academic group (GRI, Total). The objective is to understand the sismostratigraphic architecture of the platform-slope-basin system in a key area from Western Desert to Nile delta and Levant margin. Mapping of the top Jurassic and top Cretaceous show seismic geomorphology of the margin, with the cartography of the hinge line from Western Desert to Sinaï. During the Jurassic, carbonate platform show a prograding profile and a distally thickening of the external platform, non-abrupt slope profiles, and palaeovalleys incisions. Since the Cretaceous, the aggrading and retrograding mixed carbonate-siliciclastic platform show an alternation of steep NW-SE oblique segments and distally steepened segments. These structures of the platform edge are strongly controlled by the inherited tethyan transform directions. Along the hinge line, embayments are interpreted as megaslides. The basin infilling is characterised by an alternation of chaotic seismic facies and high amplitude reflectors onlaping the paleoslopes. MTC deposits can mobilize thick sedimentary

  18. The biology and fisheries of European hake, Merluccius merluccius, in the north-east Atlantic.

    Murua, Hilario

    2010-01-01

    The aim of this chapter is to review the biology and fishery, including the management, of European hake in the north-east Atlantic. The European hake is widely distributed throughout the north-east Atlantic, from Norway in the north to the Guinea Gulf in the south, and throughout the Mediterranean and Black Sea, being more abundant from the British Isles to the south of Spain. In this area, ICES (International Council for the Exploration of the Sea) recognises the existence of two stocks: the northern stock and the southern stock. Both stocks have been extensively and intensively harvested and since the beginning of the 90s have been considered to be outside safe biological limits. The northern stock, however, is currently considered to lie within safe biological limits. In any case, recovery plans were implemented for the northern stock in 2004 and for the southern stock in 2006. Despite its commercial importance, knowledge of the biology and ecology of the European hake in the North Atlantic is still quite scarce. For example, recent investigations suggest that European hake grows much faster, by a factor of two, than was considered previously. This faster growth also affects the maturity-at-age pattern of hake and the agreed maturity-at-age ogive used in the assessments. European hake is a top predator in the demersal community in the north-east Atlantic area; mainly preying on blue whiting, horse mackerel and other cupleids. In relation to the reproductive biology, European hake is considered to be a batch spawner species with indeterminate fecundity and spawning activity all year round. All these characteristics could, in turn, be interpreted as European hake adopting a more opportunistic life strategy, which is unusual for a gadoid and demersal species, and raises several questions about hake biology and ecology that require further investigation.

    The energy crisis occurring in Eastern Europe owes much to the Stalinist model of energy-intensive industrialization applied to a basically energy short region still partially isolated from the world energy market. Systemic factors are thus much more important than in the West. Due to this, solutions to the energy crisis in the East of Europe, be it through supply augmentation or conservation, belong as much in the sphere of politics and ideology as they do in the sphere of economics. The dissertation examines in a systematic manner the evolution and prospects of the energy economy in the region (Chapter 1), the present sectoral pattern of energy consumption (Chapter 2), and conversion (thermo-electric conversion in Chapter 3 and oil refining in Chapter 4). Four subsequent chapters are devoted to individual energy-consuming sectors such as industry, transportation, agriculture, and households. Finally, the potential and problems of energy conservation in Eastern Europe are analyzed in the context of broader economic policies and concerns of the states of the region. In the conclusion, topics in the energy economy of Eastern Europe requiring further study are outlined.

    Mercator-Ocean has developed a regional forecasting system at 1/12° resolution over the North East Atlantic (IBI: Iberia, Biscay and Irish), taking advantage of the recent developments in NEMO. This regional forecasting system uses boundary conditions from the Mercator-Ocean global reanalysis (GLORYS: Global Ocean ReanalYses and Simulations). The assimilation component of the Mercator Ocean system, is based on a reduced-order Kalman filter (the SEEK or Singular Extended Evolutive Kalman filter). An IAU method (Incremental Analysis Updates) is used to apply the increments in the system. The error statistics are represented in a sub-space spanned by a small number of dominant 3D error directions. The data assimilation system allows to constrain the model in a multivariate way with Sea Surface Temperature (AVHRR + Multi-satellite High resolution), together with all available satellite Sea Level Anomalies, and with in situ observations from the CORA-03 data base, including ARGO floats temperature and salinity measurements. This reanalysis covers the period from January 2002 to December 2009. In this presentation, the results obtained with this reanalysis system (1/12°) are compared to the GLORYS ones. A special focus will be made on the gain thanks to the higher resolution of the model and higher resolution of the SST assimilated in this reanalysis.

    IPANEMA, a research platform devoted to ancient and historical materials (archaeology, cultural heritage, palaeontology and past environments), is currently being set up at the synchrotron facility SOLEIL (Saint-Aubin, France; SOLEIL opened to users in January 2008). The new platform is open to French, European and international users. The activities of the platform are centred on two main fields: increased support to synchrotron projects on ancient materials and methodological research. The IPANEMA team currently occupies temporary premises at SOLEIL, but the platform comprises construction of a new building that will comply with conservation and environmental standards and of a hard X-ray imaging beamline today in its conceptual design phase, named PUMA. Since 2008, the team has supported synchrotron works at SOLEIL and at European synchrotron facilities on a range of topics including pigment degradation in paintings, composition of musical instrument varnishes, and provenancing of medieval archaeological ferrous artefacts. Once the platform is fully operational, user support will primarily take place within medium-term research projects for `hosted' scientists, PhDs and post-docs. IPANEMA methodological research is focused on advanced two-dimensional/three-dimensional imaging and spectroscopy and statistical image analysis, both optimized for ancient materials. PMID:21862858

    The main trends in the territorial changes in winter bird communities and the environmental factors determining them were analyzed based on long-term counts in the East European and West Siberian plains. These trends are reduced to a decline in the winter avian complexes (in the number of species and individuals) in the north- and eastward directions and with a decrease in the degree of sheltering and feed reserves in the habitats associated with reduction in afforestation. The specific regional features of winter East European avian complexes are the larger number of species and individuals in the nemoral forest, forest-steppe, and steppe landscapes, and inland water bodies as compared with the West Siberian avian complexes, as well as an increased influence of the degree of development and agricultural transformation of landscapes.

  3. Crustal and Lithospheric Structure across the Boundary of the East European Craton from Receiver Functions

    The Trans-European Suture Zone (TESZ), which extends from the North Sea to the Black Sea, marks a fundamental lithospheric boundary in Europe. It separates the East European Craton to the north-east, which has been stable for at least 1.45 Ga, from the younger lithosphere of Phanerozoic Europe to the south-west. In this study we use a large dataset of more than 40,000 teleseismic P- and S-receiver functions from almost 500 seismological stations to image crustal and lithospheric structure across central and eastern Europe between the Benelux and the Baltic countries. An important data source is the PASSEQ project, which deployed close to 200 temporary stations between Germany and Lithuania for two years with the aim to obtain detailed, 3D information on the upper mantle structure across the TESZ. Combining P and S observations, we find a stepwise transition in crustal thickness, spread over 200 km laterally, from on average of 30 km in Phanerozoic Europe to more than 45 km beneath the East European Craton. Individual Paleoproterozoic terranes in Lithuania can also be distinguished based on crustal thickness. Crustal layering is not resolved with the receiver functions, but a high Poisson's ratio of 0.27 is obtained for the craton, compared to 0.25 for Phanerozoic Europe, which is consistent with a thick mafic lower crust. Moho depth results show an excellent correlation with the interpretation of a seismic line in the area, lending confidence to the interpretation of deeper structures. The lithosphere-asthenosphere boundary (LAB), as mapped by S-receiver functions, is located at an average depth of 90 km beneath Phanerozoic Europe. Towards the east, the LAB is dipping to about 125 km depth beneath the Elbe Line. Below the craton, a mid-lithospheric discontinuity is found at about 80 km depth, whereas weak indications of the LAB are found at an average depth of 260 km.

    The European power systems are in the process of a new orientation. The aim of interconnecting the grids to large power systems is to facilitate and promote the exchange of electric power. The progressive extension of the synchronous parallel operation of UCPTE (Union for the Coordination of Production and Transmission of Electricity) with Eastern countries has been discussed extensively between the concerned utilities. A lot of studies have been accomplished to investigate practical and theoretical questions of the intended interconnections. In late summer 1995 the East and West German Power Systems have been interconnected; followed by the interconnection of Centrel to UCPTE. In a later stage the networks of Bulgaria and Romania shall also be connected to the UCPTE system. In order to investigate the future power exchange between the East and West European countries a feasibility study on an East-West High Power Transmission System being able to transport 4 GW between Russia, Belarus, Poland and Germany has been performed. This High Power link is to become an integral part of the Baltic Ring, which resumes the idea of creating an electrical interconnection around the Baltic Sea.

  5. Selection and Reduced Population Size Cannot Explain Higher Amounts of Neandertal Ancestry in East Asian than in European Human Populations

    Kim, Bernard Y.; Lohmueller, Kirk E.

    2015-01-01

    It has been hypothesized that the greater proportion of Neandertal ancestry in East Asians than in Europeans is due to the fact that purifying selection is less effective at removing weakly deleterious Neandertal alleles from East Asian populations. Using simulations of a broad range of models of selection and demography, we have shown that this hypothesis cannot account for the higher proportion of Neandertal ancestry in East Asians than in Europeans. Instead, more complex demographic scenarios, most likely involving multiple pulses of Neandertal admixture, are required to explain the data. PMID:25683122

    Background It was demonstrated previously that the three-locus RFLP haplotype, TaqI B-TaqI D-TaqI A (B-D-A), at the DRD2 locus constitutes a powerful genetic marker and probably reflects the most ancient dispersal of anatomically modern humans. Results We investigated TaqI B, BclI, MboI, TaqI D, and TaqI A RFLPs in 17 contemporary populations of the East European Plain and Siberia. Most of these populations belong to the Indo-European or Uralic language families. We identified three common haplotypes, which occurred in more than 90% of chromosomes investigated. The frequencies of the haplotypes differed according to linguistic and geographical affiliation. Conclusion Populations in the northwestern (Byelorussians from Mjadel'), northern (Russians from Mezen' and Oshevensk), and eastern (Russians from Puchezh) parts of the East European Plain had relatively high frequencies of haplotype B2-D2-A2, which may reflect admixture with Uralic-speaking populations that inhabited all of these regions in the Early Middle Ages.

    The tidal flats of the Wadden Sea connect the coasts of northern Germany with the North Sea. The tides shape a highly dynamic and diverse ecosystem, which has been a UNESCO natural heritage site since summer 2009. In order to gain a deeper understanding of this system, the Institute for Chemistry and Biology of the Marine Environment at the University of Oldenburg has been running a research platform at a tidal inlet between the East Frisian Islands Spiekeroog and Langeoog for almost eight years. Here, time series measurements of various hydrographical, meteorological and biogeochemical parameters are conducted. We are presenting the technical design of the platform and certain sensors as well as long-term data sets of the main hydrographical and meteorological measurements. The presentation highlights the impact of extreme events such as storm surges on suspended matter dynamics. In addition, data of periods with exceptional hydrographical conditions are shown. The results clearly demonstrate the necessity of long-term measurements in dynamic ecosystems such as the Wadden Sea in order to monitor and analyse environmental changes.

    The upper mantle structure is a subject of many seismological analysis but existent global models are often too general to depict regional variations. Our seismic model is a trial to construct a new reference model for the regional upper mantle structure in the western rim of the East European Craton. It is based on the P-wave traveltime analysis from seismograms recorded on Suwalki (SUW) seismic station belonging to the Polish Seismological Network. SUW station is situated in NE part of Poland on the East European Craton. The data from 249 natural seismic events were divided into four groups referring to the epicenters in the Western Mediterranean Sea region, Greece and Turkey region, Caucasus region and Mid-Atlantic Ridge region. Our analysis is based on the P-wave traveltimes observed up to 3000 km distance, which is sufficient to investigate upper mantle structure down to about 500 km. For each region, we established a single model which was fitted to all sections. 1D model was calculated for all regions except Jan Mayen region, for which we had to estimate 2D model because waves propagate through both oceanic and continental structure. However, the continental part of the Jan Mayen region model is similar to 1D model established for other regions. We also include data from TOR and SVEKALAPKO experiments to check the presence of the 300-km discontinuity. Our model of the upper mantle in the western rim of the East European Craton documents low velocity zone (LVZ), 300-km discontinuity and zone with the reduction of P-wave velocity above 410-km discontinuity. We attribute the existence of the 300-km discontinuity to the paleotectonic interaction between Laurentia, Baltica and Avalonia during the closure of the Tornquist Sea.

    Neanderthals were a group of archaic hominins that occupied most of Europe and parts of Western Asia from ∼30,000 to 300,000 years ago (KYA). They coexisted with modern humans during part of this time. Previous genetic analyses that compared a draft sequence of the Neanderthal genome with genomes of several modern humans concluded that Neanderthals made a small (1-4%) contribution to the gene pools of all non-African populations. This observation was consistent with a single episode of admixture from Neanderthals into the ancestors of all non-Africans when the two groups coexisted in the Middle East 50-80 KYA. We examined the relationship between Neanderthals and modern humans in greater detail by applying two complementary methods to the published draft Neanderthal genome and an expanded set of high-coverage modern human genome sequences. We find that, consistent with the recent finding of Meyer et al. (2012), Neanderthals contributed more DNA to modern East Asians than to modern Europeans. Furthermore we find that the Maasai of East Africa have a small but significant fraction of Neanderthal DNA. Because our analysis is of several genomic samples from each modern human population considered, we are able to document the extent of variation in Neanderthal ancestry within and among populations. Our results combined with those previously published show that a more complex model of admixture between Neanderthals and modern humans is necessary to account for the different levels of Neanderthal ancestry among human populations. In particular, at least some Neanderthal-modern human admixture must postdate the separation of the ancestors of modern European and modern East Asian populations. PMID:23410836

    The role of the gravitation factor in the formation of the hydrostratisphere in the East European evaporate basin is considered. The features of Paleozoic sedimentation are characterized, as are the mechanism and litho-hydrogeochemical effects of the density concentration convection of mother brines of the Low-Permian salt-bearing basin to the underlying terrigenous-carbonate Paleozoic and Proterozoic layers. It is shown that the convection processes resulted in the formation of multicomponent calcium chloride brines prevailing in the sedimentary layer of the basis; they also caused the metasomatic dolomitization of limestones with growth of their filtration capacity.

    Human skin pigmentation shows a strong positive correlation with ultraviolet radiation intensity, suggesting that variation in skin color is, at least partially, due to adaptation via natural selection. We investigated the evolution of pigmentation variation by testing for the presence of positive directional selection in 6 pigmentation genes using an empirical F(ST) approach, through an examination of global diversity patterns of these genes in the Centre d'Etude du Polymorphisme Humain (CEPH)-Diversity Panel, and by exploring signatures of selection in data from the International HapMap project. Additionally, we demonstrated a role for MATP in determining normal skin pigmentation variation using admixture mapping methods. Taken together (with the results of previous admixture mapping studies), these results point to the importance of several genes in shaping the pigmentation phenotype and a complex evolutionary history involving strong selection. Polymorphisms in 2 genes, ASIP and OCA2, may play a shared role in shaping light and dark pigmentation across the globe, whereas SLC24A5, MATP, and TYR have a predominant role in the evolution of light skin in Europeans but not in East Asians. These findings support a case for the recent convergent evolution of a lighter pigmentation phenotype in Europeans and East Asians. PMID:17182896

  12. A Semantic Cooperation and Interoperability Platform for the European Chambers of Commerce

    The LD-CAST project aims at developing a semantic cooperation and interoperability platform for the European Chambers of Commerce. Some of the key issues that this platform addresses are: The variety and number of different kinds of resources (i.e., business processes, concrete services) that concur to achieve a business service The diversity of cultural and procedural models emerging when composing articulated cross-country services The limited possibility of reusing similar services in different contexts (for instance, supporting the same service between different countries: an Italian-Romanian cooperation is different from an Italian-Polish one) The objective of the LD-CAST platform, and in particular of the semantic services provided therein, is to address the above problems with flexible solutions. We aim at introducing high levels of flexibility, both at the time of development of business processes and concrete services (i.e., operational services offered by service providers), with the possibility of dynamically binding c-services to the selected BP, according to user needs. To this end, an approach based on semantic services and a reference ontology has been proposed.

    The Trans-European Suture Zone (TESZ) represents a distinct ~3500 km long tectonic feature, which can be traced through north-western to south-eastern Europe in various models of seismic velocities (e.g., Bijwaard et al., JGR 1998, Goes et al., JGR 2000) as well as in seismic anisotropy (e.g., Babuska et al., PAGEOPH 1998). The zone manifests the significant contact zone between the Precambrian and Phanerozoic Europe. To contribute to better understanding of the structure of the upper mantle and a depth of the lithosphere-asthenosphere boundary (LAB), we analyse anisotropic parameters of body waves and suggest 3D anisotropic models of individual domains of continental mantle lithosphere. Specifically, we examine lateral variations of teleseismic P-wave travel-time deviations from about 100 teleseismic events, selected to provide a good azimuth coverage, and evaluate shear-wave splitting parameters from about 20 events recorded during passive seismic experiment PASSEQ (2006-2008), whose stations spanned across the central part of the TESZ. We derive large-scale fabrics of mantle lithosphere domains in a vicinity of the Teisseyre-Tornquist Zone (TTZ) - the NE limit of the TESZ - and the Polish Paleozoic Platform, but also further to the SW of the suture (to the southern Saxothuringian - Moldanubian Units) and to the NE (East European Craton). Variations of anisotropic signal around the central part of TESZ are surprisingly moderate, in comparison with the western part of the TESZ, and exhibit different characteristics, which we summarize as follows: (1) There is no distinct change of anisotropic signal derived either from the P-residual pattern or shear-wave splitting parameters (the fast shear-wave polarization and slow shear-wave split delay time) across the surface trace of the Teisseyre-Tornquist Zone (TTZ). (2) The most distinct change of the anisotropic signal occurs at the northern boundary of the Bohemian Massif (BM), whose mantle lithosphere consists of

    Together with the Main Tethyan Suture Zone (disrupted fragments of the Tethyan oceanic domain ), built up of ophiolitic complexes and their overlying sedimentary sequences, three deformed continental margins (continental crust overlaped by tethyan sedimentary formations) may be recognized within the Central and South-East European area, i.g. the European, the Fore-Apulian and the Apulian margins. The Main Tethyan Suture Zone groups together the : Vardar Zone, South Pannonian-Insubric Suture, Transylvaniadian and Pienidian units. The European Margin cover the Northern and Eastern Carpathains, the South Carpathians,the Balkan, Rhodope and Serebo-Maceonein Massiv. To the Fore-Apulian microcontinent belogs the North Apuseni, Central West Carpathians and Austrialpine units, as well as the most important basement of the Pannonian Depression. Apulia covers the most important part of the Dinarides and Hellenides. The Tethyan Ocean opened, in the central and southern part of the area, during the Late Anisian or Early Ladinian and spread, with different rates since the early Upper Jurassic. The rifting which precede the opening may be Late Permian (?) and Lower Triassic. In the same time within the European Plate the intracontinental aulacogene north Dobrogea-South Crimea start to develop as a pull-apart basin connected with the southeasternmost segment of the Tornquist-Teisseyre Zone. In the northern part (West Carpathains and Alps) the Tethyan Ocean opened in the Middle Jurassic being a prolongation (?) of the Central Atlantic opening. The Bukk Terrane drifted since the end of the Lower Triasic from the Apulian Margin and collided the Fore-Apulian microcontinent until the earlly Jurassic. The first compressive events occur at the Jurassic/Cretaceous boundary stressed out by kalk-alkaline volcanics developed upon oceanic crust (Mariane-type subduction) and the “closing” of the North Dobrogea-South Crimea Aulacogene.

    "13 BB star" is a dense array of 13 Reftek 151-120 broadband seismometers located in unpopulated forests in northern Poland - just on the edge of East European Craton. The shape of array was designed as a "star" with one central station and 12 station located on two circles (radius of about 30 and 60 km) around it. This geometry allows us to study seismic waves (in particular surface waves) incoming from all azimuths. Our "13 BB star" array stations are self powered (solar panels and batteries), equipped with local storage system and on-line transmission of seismic and auxiliary data using 2G and 3G cellular network. We also developed on-line application for monitoring array status (transmission, connections, power, temperature, etc.) and on-line data visualization. Main advantages of our array are: 1) 120s broadband seismometers recording with 100Hz sampling, 2) density of array - distances between neighboring stations does not exceed 30 km, 3) station placement in underground wells, 4) stations located in forests far (usually 2-3 km) from industries, roads, villages and other human activity. "13 BB star" started operating in July 2013 and since that time recorded several local, regional, and teleseismic events proving good array functionality. The scientific aim of the "13 BB star" project is development of a quantitative model of the lithosphere-asthenosphere-structure in the marginal zone of the East European Craton in northern Poland. New acquired data will be analyzed using integrated seismic methods, which will yield images of lithosphere-asthenosphere system hitherto unknown for this area. The knowledge of detailed structure of the cratonic lithosphere-asthenosphere system is crucial for the better understanding of the regional, as well as global mantle dynamics and evolution of the Earth's interior.

    The impact of European teleconnections including the East AtlanticWest Russia (EA-WR), the Scandinavia (SCA), and the East Atlantic (EA) on East Asian winter temperature variability was quantified and compared with the combined effect of the Arctic Oscillation (AO), the Western Pacific (WP), and the El-Nino Southern Oscillation (ENSO), which are originated in the Northern Hemispheric high-latitudes or the Pacific. Three European teleconnections explained 22-25 percent of the total monthly upper-tropospheric height variance over Eurasia. Regression analysis revealed warming by EA-WR and EA and cooling by SCA over mid-latitude East Asia during their positive phase and vice versa. Temperature anomalies were largely explained by the advective temperature change process at the lower troposphere. The average spatial correlation over East Asia (90-180E, 10-80N) for the last 34 winters between observed and reconstructed temperature comprised of AO, WP and ENSO effect (AWE) was approximately 0.55, and adding the European teleconnection components (ESE) to the reconstructed temperature improved the correlation up to approximately 0.64. Lower level atmospheric structure demonstrated that approximately five of the last 34 winters were significantly better explained by ESE than AWE to determine East Asian seasonal winter temperatures. We also compared the impact between EA-WR and AO on the 1) East Asian winter monsoon, 2) cold surge, and 3) the Siberian high. These three were strongly coupled, and their spatial features and interannual variation were somewhat better explained by EA-WR than AO. Results suggest that the EA-WR impact must be treated more importantly than previously thought for a better understanding of East Asian winter temperature and monsoon variability.

    Large-scale climate patterns control variability in the global carbon sink. In Europe, the North-Atlantic Oscillation (NAO) influences vegetation activity, however the East-Atlantic (EA) pattern is known to modulate NAO strength and location. Using observation-driven and modelled data sets, we show that multi-annual variability patterns of European Net Biome Productivity (NBP) are linked to anomalies in heat and water transport controlled by the NAO-EA interplay. Enhanced NBP occurs when NAO and EA are both in negative phase, associated with cool summers with wet soils which enhance photosynthesis. During anti-phase periods, NBP is reduced through distinct impacts of climate anomalies in photosynthesis and respiration. The predominance of anti-phase years in the early 2000s may explain the European-wide reduction of carbon uptake during this period, reported in previous studies. Results show that improving the capability of simulating atmospheric circulation patterns may better constrain regional carbon sink variability in coupled carbon-climate models. PMID:26777730

    PubMed

    2012-01-01

    Since the advent of European colonial expansion, medical theories of acclimatization have been inextricably related to convictions about the possibility and desirability of white settlement in the colonies, and political ideas of colonial governance. Before 1800, acclimatization theories emphasized the inherent flexibility of the human constitution and its ability to adapt to new environments. During the first half of the nineteenth century, European theorists came to highlight the vulnerability of white Europeans in the tropics to disease, degeneration, and death instead. They consequently argued that white settlement in the tropics was impossible and inadvisable. European physicians in the British and French colonies presented similar views. By contrast, their colleagues in the Dutch East Indies remained optimistic. They associated themselves with the colonial European settler community and shared their grievances against autocratic colonial rule. They presented medical theories which related acclimatization to prudent behavior, morality, and proper management of the environment, thereby downplaying the significance of climate and high temperatures. During the following decades, their views on acclimatization were transferred to the Netherlands, where they were deployed as an argument against the cultivation system, the then-current approach of colonial governance, which emphasized the trade of cash crops grown by the indigenous population, severely limited European settlement, and curtailed the rights of Europeans living in the Indies. Throughout the nineteenth century, the influence of climate and the possibility of acclimatization became recurring themes in debates about colonial governance in both the Dutch East Indies and the Netherlands.

    The chemical composition of East European (Republic of Moldova, Ukraine, and Romania) oaks was investigated profoundly for the first time in the present study and compared with American and French counterparts. Taking into account the high natural variability of oak extractives contents, the wide-ranging sampling was performed for all oak origins: 276 French oaks, 102 East European oaks of both species (Quercus robur L. and Quercus petraea Liebl.), and 56 American oaks (Quercus alba). These oaks were compared with great attention paid to the extractives, which are most important for sensorial impact in wine or spirit maturation, such as ellagitannins and principal odorant substances (aromatic aldehydes, lactones and phenols). The substances in question were studied by application of HPLC and GC-MS techniques. The pattern of all studied extractive contents allowed adequate separation of oak samples according to their geographical origin or botanical species. The highest separation rate was for American and French oaks, whereas East European samples could be partially misclassified in two sets mentioned above. The most important variables for species discrimination were whiskey lactone related variables and ellagitannins, whereas the most important features for distinguishing the origin were eugenol, 2-phenylethanol, vanillin, and syringaldehyde. These substances allowed the distinction of French and East European woods of the same species. With regard to chemical composition, East European wood held the intermediary place between American and French oaks according to their ellagitannin and whiskey lactone levels; nevertheless, it was characterized by specific high values of eugenol, aromatic aldehydes, and 2-phenylethanol.

    Mission Specific Platform (MSP) expeditions are operated by the European Consortium for Ocean Research Drilling (ECORD). Each MSP expedition is unique within the Integrated Ocean Drilling Program (IODP). In order to complement the abilities of the JOIDES Resolution and the Chikyu, the ECORD Science Operator (ESO) must source vessels and technology suitable for each MSP proposal on a case-by-case basis. The result is that ESO can meet scientific requirements in a flexible manner, whilst maintaining the measurements required for the IODP legacy programme. The process of tendering within EU journals for vessels and technology means that the planning process for each MSP Expedition starts many years in advance of the operational phase. Involvement of proposal proponents from this early stage often leads to the recognition for technological research and development to best meet the scientific aims and objectives. One example of this is the planning for the Atlantis Massif proposal, with collaborative development between the British Geological Survey (BGS) and MARUM, University of Bremen, on suitable instruments for seabed drills, with the European Petrophysics Consortium (EPC) driving the development of suitable wireline logging tools that can be used in association with such seabed systems. Other technological developments being undertaken within the European IODP community include in-situ pressure sampling for gas hydrate expeditions, deep biosphere and fluid sampling equipment and CORK technology. This multi-national collaborative approach is also employed by ESO in the operational phase. IODP Expedition 302 ACEX saw vessel and ice management support from Russia and Sweden to facilitate the first drilling undertaken in Arctic sea ice. A review of MSP expeditions past, present and future reveal the significant impact of European led operations and scientific research within the current IODP programme, and also looking forward to the start of the new International

    Using principal component (PC) analysis, we studied the genetic constitution of 3,112 individuals from Europe as portrayed by more than 270,000 single nucleotide polymorphisms (SNPs) genotyped with the Illumina Infinium platform. In cohorts where the sample size was >100, one hundred randomly chosen samples were used for analysis to minimize the sample size effect, resulting in a total of 1,564 samples. This analysis revealed that the genetic structure of the European population correlates closely with geography. The first two PCs highlight the genetic diversity corresponding to the northwest to southeast gradient and position the populations according to their approximate geographic origin. The resulting genetic map forms a triangular structure with a) Finland, b) the Baltic region, Poland and Western Russia, and c) Italy as its vertexes, and with d) Central- and Western Europe in its centre. Inter- and intra- population genetic differences were quantified by the inflation factor lambda (lambda) (ranging from 1.00 to 4.21), fixation index (F(st)) (ranging from 0.000 to 0.023), and by the number of markers exhibiting significant allele frequency differences in pair-wise population comparisons. The estimated lambda was used to assess the real diminishing impact to association statistics when two distinct populations are merged directly in an analysis. When the PC analysis was confined to the 1,019 Estonian individuals (0.1% of the Estonian population), a fine structure emerged that correlated with the geography of individual counties. With at least two cohorts available from several countries, genetic substructures were investigated in Czech, Finnish, German, Estonian and Italian populations. Together with previously published data, our results allow the creation of a comprehensive European genetic map that will greatly facilitate inter-population genetic studies including genome wide association studies (GWAS).

When the PC analysis was confined to the 1,019 Estonian individuals (0.1% of the Estonian population), a fine structure emerged that correlated with the geography of individual counties. With at least two cohorts available from several countries, genetic substructures were investigated in Czech, Finnish, German, Estonian and Italian populations. Together with previously published data, our results allow the creation of a comprehensive European genetic map that will greatly facilitate inter-population genetic studies including genome wide association studies (GWAS).

    Bats are known to host viruses closely related to important human coronaviruses (HCoVs), such as HCoV-229E, severe-acute respiratory syndrome coronavirus (SARS-CoV), and Middle East respiratory syndrome CoV (MERS-CoV). As RNA viruses may coevolve with their hosts, we sought to investigate the closest sister taxon to bats, the Eulipotyphla, and screened European hedgehogs (Erinaceus europaeus) from Germany for CoV by nested reverse transcriptase PCR. A novel betacoronavirus species in a phylogenetic sister relationship to MERS-CoV and clade c bat CoVs was detected and characterized on the whole-genome level. A total of 58.9% of hedgehog fecal specimens were positive for the novel CoV (EriCoV) at 7.9 log10 mean RNA copies per ml. EriCoV RNA concentrations were higher in the intestine than in other solid organs, blood, or urine. Detailed analyses of the full hedgehog intestine showed the highest EriCoV concentrations in lower gastrointestinal tract specimens, compatible with viral replication in the lower intestine and fecal-oral transmission. Thirteen of 27 (48.2%) hedgehog sera contained non-neutralizing antibodies against MERS-CoV. The animal origins of this betacoronavirus clade that includes MERS-CoV may thus include both bat and nonbat hosts. PMID:24131722

    18 chronic diseases were investigated in a population of 13,115 women living in six settings of West- (Avon UK, the Isle of Man), Central- (the Czech Republic and the Slovak Republic) and East-Europe (the Ukraine and Russia), that collaborate in the European Longitudinal Study of Pregnancy and Childhood (ELSPAC project). In prenatal questionnaires filled in after the first half of pregnancy, women reported 25,795 chronic diseases they ever suffered, out of them 11,188 having in present pregnancies. In the whole sample, lifelong prevalence was 11,2%, and prevalence in pregnancy 4,8% which means that 43,4% of all chronic diseases recurred in pregnancy. Up to mean age of 255 years in the whole sample, 39,6% women reported ever having indigestion, 29% back pains, 22,6% migraine, about 16% haemorrhoids, hay fever and eczema, about 10% varicose veins, anorexia nervosa, heavy depression and kidney diseases, over 5% rheumatism and 4% asthma. Less prevalent were infections of pelvic organs, febrile convulsions, joint inflammations, stomach ulcers, psoriasis and epilepsy. Lifetime prevalence of chronic diseases and their prevalence in pregnancy were the highest in the western zone and decreased eastwards, but recurrence grew in the opposite direction, being the highest in the eastern zone. The variation of each morbidity indicator is followed in all diseases between geographical zones as well as between individual study centres. PMID:18822844

    The spinal perineurial cyst (Tarlov) is a dilatation between the perineurium and endoneurium of spinal nerve roots, located at level of the spinal ganglion and filled with cerebrospinal fluid but without communication with the perineurial subarachnoid space. The aim of the study was to evaluate it incidence among East-European patients. The retrospective data collected during various magnetic resonance spinal examinations and stored on the picture archiving and communication system was analyzed for an incidence of perineurial cysts. From among 842 patients that underwent examination, 75 cases perineurial cysts were revealed. In 22 cases single anomalies were found. In remaining 53 cases, multiple uni- or less frequently bilateral changes were noted. The most common position was the sacral canal, particularly the level of S2 and S3. Occasionally, cysts were also visible on the cervical, thoracic and lumbar level. Incidence of sacral perineurial cysts was significantly higher in females than in males. Similar data was found for single and multiple changes despite of their localization. Insignificant changes were seen for patient age and cyst size. Perineurial spinal cysts were the most frequently observed on the sacral level and such changes were more common in females. PMID:23936511

    The Holocene climate and vegetation dynamics in the broad-leaved forest zone of the central part of the East European plain have been reconstructed on the base of pollen, plant macrofossil, testate amoebae and radiocarbon data from the mire Klukva (N 53.834812, E 36.252488), located in the kast depression in the Upper Oka River basin (Tula region, European Russia). The reconstruction of main parameters of past climate (the mean annual temperature precipitation) was carried out by the "Best Modern Analog" approach. Reconstructions of vegetation show that in the early Holocene the territory was occupied mainly by birch and pine-birch forests. Significant changes in the plant cover of the Upper Oka River basin are attributed to the 7.5 cal kyr BP). The climatic conditions were favorable for development of the broad-leaved forests those persisted in this area up to industrial period. In the 17th century, when the population density greatly increased and watersheds were ploughed, natural vegetation communities were gradually destroyed and transformed into agricultural landscapes. According to obtained climatic reconstructions the period 10-8.5 cal kyr BP was relatively cold and wet, when the mean annual temperature was in 3°C lower and precipitation was in 50-100 mm higher then nowadays. The significant climate warming occurred in about 7.0-5.0 cal kyr BP (The Holocene thermal maximum): the mean annual temperature in 2°C exceeded the modern value and precipitation was close to that. The environment conditions were drier due to decrease of effective moisture. In the second part of the Holocene the sequence of second-, and even third-order climatic oscillations expressed against the background of the overall slight trend towards cooling have been determined. The most pronounced cool and wet intervals were reconstructed in 2.5-2.0 cal kyr BP and 1.5-1.3 cal kyr BP. The mean annual temperature decreased in 1.5-2 °C and precipitation rose in 200 mm in compare to modern

    The advent of DNA sequencing technologies and the various applications that can be performed will have a dramatic effect on medicine and healthcare in the near future. There are several DNA sequencing platforms available on the market for research and clinical use. Based on the medical laboratory scientist or researcher's needs and taking into consideration laboratory space and budget, one can chose which platform will be beneficial to their institution and their patient population. Although some of the instrument costs seem high, diagnosing a patient quickly and accurately will save hospitals money with fewer hospital stays and targeted treatment based on an individual's genetic make-up. By determining the type of disease an individual has, based on the mutations present or having the ability to prescribe the appropriate antimicrobials based on the knowledge of the organism's resistance patterns, the clinician will be better able to treat and diagnose a patient which ultimately will improve patient outcomes and prognosis.

    In order to study the lithospheric structure in southern Ukraine, a seismic wide-angle reflection/refraction project DOBRE-4 was conducted. The 500 km-long profile starts in the SW from the Alpine/Variscan North Dobrudja fold-thrust belt, being part of the Trans-European Suture Zone. It runs to the NE, mostly along the NW Black Sea coastal plain, towards the center of the Precambrian Ukrainian Shield. The field acquisition in October 2009 included 13 chemical shot points with charge sizes 600-1000 kg every 35-50 km and 230 recording stations, every ~2.5 km. The high data quality allows modelling of the P- and S-wave velocity structure along the profile. Two methods were used for the modelling of the seismic data. At first, ray-tracing trial-and-error modelling was developed using arrivals of major refracted and reflected P- and S-wave phases. Next, the amplitudes of the recorded phases were analysed using finite-difference full waveform method. The resulting velocity model shows fairly homogeneous structure of the middle to lower crust both vertically and laterally. The situation is different in the upper crust, with Vp velocities decreasing upwards from c. 6.35 at 15-20 km to 5.9-5.8 km/s at the top of the crystalline basement and to c. 5.15 to 3.80 km/s in Neoproterozoic and Palaeozoic and to 2.70 to 2.30 km/s in Mesozoic strata. Below the upper crust the Vp smoothly increases downward, from c. 6.5 to 6.7-6.8 km/s near the crustal base, making it difficult to differentiate between the middle and lower crust. No Vp velocities exceeding 6.80 km/s have been recorded even in the lowermost part of the crust, unlike in similar profiles on the East European Craton. There is no clear change in the velocity field when moving laterally from the Precambrian platform into the younger tectonic units to the SW.

    This monograph examines the employment of a European based U.S. heavy division in a contingency in the Middle East. Applicable theory is described and developed against the historical lens of armored campaigns in desert regions and then is used to develop the research paper's product: employment considerations. The strategic setting of the Middle East demands sustained attention from the United States. We can expect continued trouble and violence resulting from the diverse religious, cultural, economic, and military pressures within the area. We will most likely see United States interests in protecting sovereign nations and encouraging peace in the region. Since the diminished Soviet threat in Europe no longer fixes divisions in position, a heavy division could be available for employment in the adjacent theater, the Middle East. The criteria introduced to develop the analysis are the dynamics of combat power: maneuver, firepower, protection and leadership. These are examined from theoretical and historical frames of reference that include the German World War II North African campaign, Arab-Israeli wars, and the recent Iran-Iraq War.

  17. Cratonic platform and foredeep response to plate margin convergence: Devonian through Mississippian subsidence history in western Montana and east-central Idaho

    Devonian and Mississippian sedimentary rocks of western Montana and east-central Idaho were deposited on a cratonic platform that faced a northern extension of the Antler foredeep. Subsidence analyses of this sequence and isopach maps illustrate regional patterns of subsidence related to convergence along the western North American plate margin. Tectonic stresses affected deposition on platform areas which were hundreds of kilometers inboard from the ancient continental margin. Wavelengths of paleostructural elements, tectonic inversion of these structures (i.e., transition of a paleohigh into a depocenter), and time scales involved in the inversion process cannot be attributed solely to flexure or to vertical displacements by in-plane stresses but suggest reactivation of Precambrian structural trends. Late Devonian (Frasnian) platform sedimentation began during a brief interval of increased subsidence across western Montana. This interval of increased platform subsidence is greater than a Late Devonian eustatic sea level rise (determined from subsidence analyses of Devonian strata from stable cratonic areas) and suggests some tectonic event must have influenced subsidence in Montana. Thin uppermost Devonian Strata contain numerous unconformities that may be related to flexure of the platform plus eustatic sea level fluctuations. Rapid subsidence across Montana during the Early Mississippian (Kinderhookian) resulted in a condensed platform sequence, which is overlain by deep water shaly carbonates. Rapid subsidence continued into the Osagean then slowed, allowing progradation of carbonate platform facies across Montana. A regional karst surface on top of the Meramecian platform coincides with conglomerate deposition and increased subsidence rates in the foredeep; unconformity durations on the platform also increase to the east.

    The importance of the process of Neolithization for the genetic make-up of European populations has been hotly debated, with shifting hypotheses from a demic diffusion (DD) to a cultural diffusion (CD) model. In this regard, ancient DNA data from the Balkan Peninsula, which is an important source of information to assess the process of Neolithization in Europe, is however missing. In the present study we show genetic information on ancient populations of the South-East of Europe. We assessed mtDNA from ten sites from the current territory of Romania, spanning a time-period from the Early Neolithic to the Late Bronze Age. mtDNA data from Early Neolithic farmers of the Starčevo Criş culture in Romania (Cârcea, Gura Baciului and Negrileşti sites), confirm their genetic relationship with those of the LBK culture (Linienbandkeramik Kultur) in Central Europe, and they show little genetic continuity with modern European populations. On the other hand, populations of the Middle-Late Neolithic (Boian, Zau and Gumelniţa cultures), supposedly a second wave of Neolithic migration from Anatolia, had a much stronger effect on the genetic heritage of the European populations. In contrast, we find a smaller contribution of Late Bronze Age migrations to the genetic composition of Europeans. Based on these findings, we propose that permeation of mtDNA lineages from a second wave of Middle-Late Neolithic migration from North-West Anatolia into the Balkan Peninsula and Central Europe represent an important contribution to the genetic shift between Early and Late Neolithic populations in Europe, and consequently to the genetic make-up of modern European populations.

    European long-term environmental research infrastructures (often referred as ESFRI RIs) are the core facilities for providing services for scientists in their quest for understanding and predicting the complex Earth system and its functioning that requires long-term efforts to identify environmental changes (trends, thresholds and resilience, interactions and feedbacks). Many of the research infrastructures originally have been developed to respond to the needs of their specific research communities, however, it is clear that strong collaboration among research infrastructures is needed to serve the trans-boundary research requires exploring scientific questions at the intersection of different scientific fields, conducting joint research projects and developing concepts, devices, and methods that can be used to integrate knowledge. European Environmental research infrastructures have already been successfully worked together for many years and have established a cluster - ENVRI cluster - for their collaborative work. ENVRI cluster act as a collaborative platform where the RIs can jointly agree on the common solutions for their operations, draft strategies and policies and share best practices and knowledge. Supporting project for the ENVRI cluster, ENVRIplus project, brings together 21 European research infrastructures and infrastructure networks to work on joint technical solutions, data interoperability, access management, training, strategies and dissemination efforts. ENVRI cluster act as one stop shop for multidisciplinary RI users, other collaborative initiatives, projects and programmes and coordinates and implement jointly agreed RI strategies.

    The design and manufacture of components and systems underpin the European and indeed worldwide photonics industry. Optical materials and photonic components serve as the basis for systems building at different levels of complexity. In most cases, they perform a key function and dictate the performance of these systems. New products and processes will generate economic activity for the European photonics industry into the 21 st century. However, progress will rely on Europe's ability to develop new and better materials, components and systems. To achieve success, photonic components and systems must: •be reliable and inexpensive •be generic and adaptable •offer superior functionality •be innovative and protected by Intellectual Property •be aligned to market opportunities The challenge in the short-, medium-, and long-term is to put a coordinating framework in place which will make the European activity in this technology area competitive as compared to those in the US and Asia. In the short term the aim should be to facilitate the vibrant and profitable European photonics industry to further develop its ability to commercialize advances in photonic related technologies. In the medium and longer terms the objective must be to place renewed emphasis on materials research and the design and manufacturing of key components and systems to form the critical link between science endeavour and commercial success. All these general issues are highly relevant for the component intensive broadband communications industry. Also relevant for this development is the convergence of data and telecom, where the low cost of data com meets with the high reliability requirements of telecom. The text below is to a degree taken form the Strategic Research Agenda of the Technology Platform Photonics 21 [1], as this contains a concerted effort to iron out a strategy for EU in the area of photonics components and systems.

    In this study, we present a new quantitative method to measure iris colour based on high-resolution photographs. We applied this method to analyse iris colour variation in a sample of individuals of East Asian, European and South Asian ancestry. We show that measuring iris colour using the coordinates of the CIELAB colour space uncovers a significant amount of variation that is not captured using conventional categorical classifications, such as 'brown', 'blue' or 'green'. We tested the association of a selected panel of polymorphisms with iris colour in each population group. Six markers showed significant associations with iris colour in the European sample, three in the South Asian sample and two in the East Asian sample. We also observed that the marker HERC2 rs12913832, which is the main determinant of 'blue' versus 'brown' iris colour in European populations, is also significantly associated with central heterochromia in the European sample.

    The aim of ESPAS platform is to integrate heterogeneous data from the earth's thermosphere, ionosphere, plasmasphere and magnetosphere. ESPAS supports the systematic exploration of multipoint measurements from the near-Earth space through homogenised access to multi-instrument data. It provides access to more than 40 datasets: Cluster, EISCAT, GIRO, DIAS, SWACI, CHAMP, SuperDARN, FPI, magnetometers INGV, SGO, DTU, IMAGE, TGO, IMAGE/RPI, ACE, SOHO, PROBA2, NOAA/POES, etc. The concept of extensibility to new data sets is an important element in the ESPAS architecture. Within the first year of the project, the main components of the system have been developed, namely, the data model, the XML schemas for metadata exchange format, the ontology, the wrapper installed at the data nodes so that the main platform harvest the metadata, the main platform built on the D-NET framework and the GUI with its designed workflows. The first working prototype supports the search for datasets among a selected number of databases (i.e., EDAM, DIAS, Cluster, SWACI data). The next immediate step would be the implementation of search for characteristics within the datasets. For the second release we are planning to deploy tools for conjunctions between ground-space and space-space and for coincidences. For the final phase of the project the ESPAS infrastructure will be extensively tested through the application of several use cases, designed to serve the needs of the wide interdisciplinary users and producers communities, such as the ionospheric, thermospheric, magnetospheric, space weather and space climate communities, the geophysics community, the space communications engineering, HF users, satellite operators, navigation and surveillance systems, and space agencies. The final ESPAS platform is expected to be delivered in 2015.

  7. Crustal high-velocity anomaly at the East European Craton margin in SE Poland (TESZ) modelled by 3-D seismic tomography of refracted and reflected arrivals

    Środa, Piotr; Dec, Monika

    2016-04-01

    The area of Trans-European Suture Zone in SE Poland represents a contact of major tectonic units of different consolidation age - from the Precambrian East European Craton, through Palaeozoic West European Platform to Cenozoic Carpathian orogen. The region was built by several phases of crustal accretion, which resulted in a complex collage of tectonic blocks. In 2000, this region was studied by several seismic wide-angle profiles of CELEBRATION 2000 experiment, providing a dense coverage of seismic data in SE Poland and allowing for detailed investigations of the crustal structure and properties in this area. Beneath the marginal part of the EEC, the 2-D modelling of in-line data form several CELEBRATION profiles revealed a prominent high P-wave velocity anomaly in the upper crust, with Vp of 6.7-7.1 km/s, starting at 10-16 km depth (e.g., Środa et al., 2006). Anomalously high velocities are observed in the area located approximately beneath Lublin trough, to the NE of Teisseyre-Tornquist Zone. Based on 3-D tomography of first arrivals of in- and off-line CELEBRATION 2000 recordings (Malinowski et al., 2008), elevated velocities are also reported in the same area and seem to continue to the SW, off the craton margin. Gravimetric modelling also revealed anomalously high density in the same region at similar depths. High seismic velocities and densities are interpreted as indicative for a pronounced mafic intrusion, possibly related to extensional processes at the EEC margin. Previous 3-D models of the high-velocity intrusion were based on first arrivals (crustal refractions) only. In this study, also off-line reflections (not modelled up to now) are used, in order to enlarge the data set and to better constrain the geometry and properties of the velocity anomaly. A code for 3-D joint tomographic inversion of refracted and reflected arrivals, with model parametrization allowing for velocity discontinuities was used (Rawlinson, 2007). With this approach, besides the

    The paper presents the background, the main elements and the contradictions of the reform of educational administration in Hungary in the late '80s in a Central and East European perspective. It also tries to provide an analysis of the challenges that have emerged with the political changes of the '90s. The introductory part of the paper analyses the differences between policies of decentralization in Eastern and Western Europe. In the second part, the most important changes introduced by the 1985 Hungarian Education Act are summarized, and the policy background of these changes is presented. It is assumed that the policy behind the decentralization measures had a negative character: it intended more to abolish the existing structures of control than to establish new ones. In the final part of the paper those factors are presented which may play a role in the future for or against the policy of decentralization.

    Mercator-Ocean has developed a regional forecasting system at 1/12° resolution over the North East Atlantic (IBI: Iberia, Biscay and Irish), taking advantage of the recent developments in NEMO. A reanalysis, called IBIRYS, was performed with the IBI system on the 2002-2012 period. The physical model was coupled on-line with the biogeochemical component of NEMO based on the PISCES model. The model was forced by ERA-interim products (every 3 hours) including the atmospheric pressure. In addition to atmospheric forcing, the model included astronomical tidal forcing. This regional forecasting system used boundary conditions from the Mercator-Ocean global reanalysis (GLORYS: GLobal Ocean ReanalYses and Simulations).The assimilation component SAM2 (Mercator Ocean assimilation system), was based on a reduced-order Kalman filter (the SEEK or Singular Extended Evolutive Kalman filter). An IAU method (Incremental Analysis Updates) was used to apply the increments in the system. The error statistics were represented in a sub-space spanned by a small number of dominant 3D error directions. A 3D-Var scheme corrected for the slowly evolving large-scale biases in temperature and salinity. The data assimilation system allowed to constrain the model in a multivariate way with Sea Surface Temperature (AVHRR + Multi-satellite High resolution), together with all available satellite Sea Level Anomalies, and with in situ observations from the CORA-03 data base, including ARGO floats temperature and salinity measurements. In this presentation, the results obtained with IBIRYS are compared to GLORYS results. The consistency of the IBIRYS and GLORYS results at large scales is demonstrated. The capacity of IBIRYS to provide useful information at high frequencies in the North East Atlantic is shown. The biogeochemical results of IBIRYS are evaluated.

  10. Organizational choices for international cooperation: East-West European cooperation on regional environmental problems

    NASA Astrophysics Data System (ADS)

    Connolly, Barbara Mary

    This dissertation applies theoretical insights from transaction cost economics to explain and predict the organizational form of cooperative agreements between Eastern and Western Europe in areas of regional environmental and political concern. It examines five contracting problems related to nuclear power safety and acid rain, and describes the history of international negotiations to manage these problems. It argues that the level of interdependence in a given issue area, or costly effects experienced in one state due to activities and decisions of other states, along with the level of transactional vulnerability, or sunk costs invested in support of a particular contractual relationship among these states, are key determinants of the governance structures states choose to facilitate cooperation in that issue area. Empirically, the dissertation traces the evolution of three sets of institutional arrangements related to nuclear safety: governance for western nuclear safety assistance to Eastern Europe, negotiations of a global convention on safety standards for nuclear power plants, and contracts among utilities and multilateral banks to build new nuclear power plants in Eastern Europe. Next it studies European acid rain, chronicling the history of international acid rain controls within the UNECE Convention on Long-Range Transboundary Air Pollution (LRTAP) and the European Union, and finally examining institutional arrangements for burden-sharing to promote European bargains on emissions reduction, including bilateral aid transfers and proposals for multilateral burden sharing. Political actors have a wide range of choice among institutional arrangements to facilitate international cooperation, from simple market-type exchanges, to arbitration-type regimes that provide information and enhance reputation effects, to self-enforcing agreements such as issue-linkage, to supranational governance. The governance structures states devise to manage their cooperative

    ABSTRACT In 2012, the first cases of infection with the Middle East respiratory syndrome coronavirus (MERS-CoV) were identified. Since then, more than 1,000 cases of MERS-CoV infection have been confirmed; infection is typically associated with considerable morbidity and, in approximately 30% of cases, mortality. Currently, there is no protective vaccine available. Replication-competent recombinant measles virus (MV) expressing foreign antigens constitutes a promising tool to induce protective immunity against corresponding pathogens. Therefore, we generated MVs expressing the spike glycoprotein of MERS-CoV in its full-length (MERS-S) or a truncated, soluble variant of MERS-S (MERS-solS). The genes encoding MERS-S and MERS-solS were cloned into the vaccine strain MVvac2 genome, and the respective viruses were rescued (MVvac2-CoV-S and MVvac2-CoV-solS). These recombinant MVs were amplified and characterized at passages 3 and 10. The replication of MVvac2-CoV-S in Vero cells turned out to be comparable to that of the control virus MVvac2-GFP (encoding green fluorescent protein), while titers of MVvac2-CoV-solS were impaired approximately 3-fold. The genomic stability and expression of the inserted antigens were confirmed via sequencing of viral cDNA and immunoblot analysis. In vivo, immunization of type I interferon receptor-deficient (IFNAR−/−)-CD46Ge mice with 2 × 105 50% tissue culture infective doses of MVvac2-CoV-S(H) or MVvac2-CoV-solS(H) in a prime-boost regimen induced robust levels of both MV- and MERS-CoV-neutralizing antibodies. Additionally, induction of specific T cells was demonstrated by T cell proliferation, antigen-specific T cell cytotoxicity, and gamma interferon secretion after stimulation of splenocytes with MERS-CoV-S presented by murine dendritic cells. MERS-CoV challenge experiments indicated the protective capacity of these immune responses in vaccinated mice. IMPORTANCE Although MERS-CoV has not yet acquired extensive distribution

    The honeybee waggle dance, through which foragers advertise the existence and location of a food source to their hive mates, is acknowledged as the only known form of symbolic communication in an invertebrate. However, the suggestion, that different species of honeybee might possess distinct ‘dialects’ of the waggle dance, remains controversial. Furthermore, it remains unclear whether different species of honeybee can learn from and communicate with each other. This study reports experiments using a mixed-species colony that is composed of the Asiatic bee Apis cerana cerana (Acc), and the European bee Apis mellifera ligustica (Aml). Using video recordings made at an observation hive, we first confirm that Acc and Aml have significantly different dance dialects, even when made to forage in identical environments. When reared in the same colony, these two species are able to communicate with each other: Acc foragers could decode the dances of Aml to successfully locate an indicated food source. We believe that this is the first report of successful symbolic communication between two honeybee species; our study hints at the possibility of social learning between the two honeybee species, and at the existence of a learning component in the honeybee dance language.

  13. New SHRIMP zircon age constraints on the evolution of crystalline basement in Eastern Lithuania (East European Craton)

    The crystalline crust in Lithuania was formed between ca. 1.9 and 1.8 Ga during the Svecofennian orogeny. Major tectonic domains include the West Lithuanian Granulite Domain and the East Lithuanian Domain occupying either side of the Mid-Lithuanian Suture Zone, and in the southeast the Belarus-Podlasie-Granulite Belt. The study area is situated within the Drūkšiai-Polotsk Deformation Zone (DPDZ) in the East Lithuanian Domain, which is well defined by gravity and magnetic linear anomalies. In this study, zircons separated from two deformed granitoids of the DPDZ were dated using the Sensitive High-Resolution Ion Microprobe (SHRIMP IIe) at the Korea Basic Science Institute (KBSI). The Novikai-1 granite defines two age groups of zircon. One group represents the inherited zircon cores dated at 1907, 1900, and 1887 Ma, respectively. The other comprises the magmatic age of metamictized cores and overgrowth rims that yielded a mean 207Pb/206Pb age of 1793.2±6.5 Ma (n=19, MSWD=2.4). The latter is broadly similar to the zircon 207Pb /206Pb age (1830±20 Ma) of charnockitic rocks in the West Lithuanian Granulite Domain (Claesson et al., 2001) and to 1.81-1.77 Ga of TIB-1 type granitoids in Sweden (Åhäll & Larson 2000; Andersson et al., 2004). This felsic magmatism suggests the development of an active continental margin of the East European Craton in the late Palaeoproterozoic. The Tverečius deformed grandiorite contains well-preserved and oscillatory-zoned zircon grains, which yielded a mean 207Pb/206Pb age of 1542±17 (n=20, MSWD=1.8). This age is consistent with that of the rapakivi granitoids in the Svecofennian domain and of the Mesoproterozoic AMCG granitoids in the Mazury complex, NE Poland (Wiszniewska et al., 2007). Taken together, magmatic activities in the crystalline basement of eastern Lithuania thus correlate well with those in the Baltic Shield, defined by both the Paleoproterozoic orogenic event and the Mesoproterozoic intracratonic extension. This is a

    The 'Standard European Vector Architecture' database (SEVA-DB, http://seva.cnb.csic.es) was conceived as a user-friendly, web-based resource and a material clone repository to assist in the choice of optimal plasmid vectors for de-constructing and re-constructing complex prokaryotic phenotypes. The SEVA-DB adopts simple design concepts that facilitate the swapping of functional modules and the extension of genome engineering options to microorganisms beyond typical laboratory strains. Under the SEVA standard, every DNA portion of the plasmid vectors is minimized, edited for flaws in their sequence and/or functionality, and endowed with physical connectivity through three inter-segment insulators that are flanked by fixed, rare restriction sites. Such a scaffold enables the exchangeability of multiple origins of replication and diverse antibiotic selection markers to shape a frame for their further combination with a large variety of cargo modules that can be used for varied end-applications. The core collection of constructs that are available at the SEVA-DB has been produced as a starting point for the further expansion of the formatted vector platform. We argue that adoption of the SEVA format can become a shortcut to fill the phenomenal gap between the existing power of DNA synthesis and the actual engineering of predictable and efficacious bacteria.

The structures are adjacent to a zone along which crust was reworked and/or accreted to the EEC during Late Palaeozoic-Triassic times. The objective of the present study is deriving constraints from available geological and geophysical data for understanding the tectonic setting and processes controlling the evolution of the southern margin of the EEC. The study area includes the inverted southernmost part of the intracratonic DDB Donbas Foldbelt (DF), its south-eastern prolongation along the margin of the EEC the sedimentary succession of the Karpinsky Swell (KS), the south-western part of the Peri-Caspian Basin (PCB) and the Scythian Plate. According to the structure of the sedimentary basin, the DF and the KS form a single linear structure, represented by the uplift of Palaeozoic rocks, with the exposure of Carboniferous coal-bearing rocks in the DF, and by deep trough (down to the depth of 20 km and more) on the top of the crystalline Precambrian basement. The 3D gravity back-stripping analysis, implemented to test the sediment structure, reveals a distinct elongate zone of positive sediment corrected anomalies along the axis of the DF-KS and strong positive anomaly in the PCB. This is caused by heterogeneous lithosphere structure below the basin: Moho topography and/or the existence of a high density material in the crystalline crust and uppermost mantle. Our previous investigations have supported the existence of high-density body in the crystalline crust along the DDB axis. The

    The High Energy Density science instrument (HED) at the European XFEL, Hamburg, Germany will provide unique experimental possibilities for the investigation of near solid material driven to extreme states and will also establish a new platform to study materials response to shock compression. HED is located at the SASE2 undulator, which provides up to 27000 pulses per second with about 1012 photons per pulse, photon energies between 3 and 24 keV and pulse lengths of 2 - 100 fs. Self-seeding is foreseen, as well as natural bandwidth (BW) SASE radiation. In addition, energy BW of 10-4 and 10-6 will be available through monochromators. Focussing is based on CRL optics, which will allow to provide beam sizes of 2 μm, 10-20 μm and 150 - 260 μm at the sample position. Samples will be driven to extreme states by different types of optical lasers (either 200 kHz/3 mJ/15 fs, 10 Hz/100 TW/30 fs or 10 Hz/100J/ns), the pump-probe FEL beam (delays of up to 2 -23 ps for 5 -20 keV using a split-and-delay unit) and pulsed magnetic fields (up to 50 T). Pump probe experiments can be performed at adapted repetition rates (4.5 MHz, 1 - 10 Hz, single shot). X-ray techniques comprise diffraction, imaging and spectroscopic methods. User operation is planned for fall 2017. We will present the science case of HED, the current layout and present ideas on first shock compression experiments.

  20. A new model of the upper mantle structure beneath the western rim of the East European Craton

    Dec, M.; Malinowski, M.; Perchuc, E.

    2014-02-01

    In this article we present a new 1-D P wave seismic velocity model (called MP1-SUW) of the upper mantle structure beneath the western rim of the East European Craton (EEC) based on the analysis of the earthquakes recorded at the Suwałki (SUW) seismic station located in NE Poland which belongs to the Polish Seismological Network (PLSN). This analysis was carried out due to the fact that in the wavefield recorded at this station we observed a group of reflected waves after expected P410P at epicentral distances 2300-2800 km from SUW station. Although the existing global models represent the first arrivals, they do not represent the full wavefield with all reflected waves because they do not take into account the structural features occurring regionally such as 300 km discontinuity. We perform P wave traveltime analysis using 1-D forward ray-tracing modelling for the distances up to 3000 km. We analysed 249 natural seismic events that were divided into four azimuthal spans with epicentres in the western Mediterranean Sea region (WMSR), the Greece and Turkey region (GTR), the Caucasus region (CR) and the part of the North Atlantic Ridge near the January Mayen Island (JMR). Events from each group were sorted into four seismic sections respectively. The MP1-SUW model documents bottom of the asthenospheric low velocity zone (LVZ) at the depth of 220 km, 335 km discontinuity and the zone with the reduction of P wave velocity atop 410 km discontinuity which is depressed to 440 km depth. The nature of a regionally occurring 300 km boundary here we explained by tracing the ancient subduction regime related to the closure of the Iapetus Ocean, the Rheic Ocean and the Tornquist Sea.

  1. Unlocking the potential of tropical root crop biotechnology in east Africa by establishing a genetic transformation platform for local farmer-preferred cassava cultivars

    Cassava genetic transformation capacity is still mostly restricted to advanced laboratories in the USA, Europe and China; and its implementation and maintenance in African laboratories has remained scarce. The impact of transgenic technologies for genetic improvement of cassava will depend largely on the transfer of such capabilities to researchers in Africa, where cassava has an important socioeconomic niche. A major constraint to the development of genetic transformation technologies for cassava improvement has been the lack of an efficient and robust transformation and regeneration system. Despite the success achieved in genetic modification of few cassava cultivars, including the model cultivar 60444, transgenic cassava production remains difficult for farmer-preferred cultivars. In this study, a protocol for cultivar 60444 developed at ETH Zurich was successfully implemented and optimized to establish transformation of farmer-preferred cassava cultivars popular in east Africa. The conditions for production and proliferation of friable embryogenic calli (FEC) and Agrobacterium-mediated transformation were optimized for three east African farmer-preferred cultivars (Ebwanatereka, Kibandameno and Serere). Our results demonstrated transformation efficiencies of about 14–22 independent transgenic lines per 100 mg of FEC for farmer-preferred cultivars in comparison to 28 lines per 100 mg of the model cultivar 60444. The presence, integration and expression of the transgenes were confirmed by PCR, Southern blot analysis and histochemical GUS assay. This study reports the establishment of a cassava transformation platform at International Institute of Tropical Agriculture (IITA) hosted by Biosciences eastern and central Africa (BecA) hub in Kenya and provides the basis for transferring important traits such as virus resistance and prolonged shelf-life to farmer-preferred cultivars in east Africa. We anticipate that such platform will also be instrumental to transfer

    Studies of vitamin D-related genetic variants and breast cancer have been inconsistent. This study aimed to investigate associations of vitamin D-related polymorphisms and breast cancer risk among European and East Asian women and potential interactions with menopausal status and breast tumour subtypes. Data from a case-control study of breast cancer (1037 cases and 1050 controls) were used to assess relationships between 21 polymorphisms in two vitamin D-related genes (GC and VDR) and breast cancer risk. Odds ratios were calculated in stratified analyses of European and East Asian women, using logistic regression in an additive genetic model. An interaction term was used to explore modification by menopausal status. Polytomous regression was used to assess heterogeneity by breast tumour subtype. False discovery rate adjustments were conducted to account for multiple testing. No association was observed between GC or VDR polymorphisms and breast cancer risk. Modification of these relationships by menopausal status was observed for select polymorphisms in both Europeans (VDR rs4328262 and rs11168292) and East Asians (GC rs7041 and VDR rs11168287). Heterogeneity by tumour subtype was seen for three VDR polymorphisms (rs1544410, rs7967152 and rs2239186) among Europeans, in which associations with ER-/PR-/HER2+ tumours, but not with other subtypes, were observed. In conclusion, associations between vitamin D-related genetic variants and breast cancer were not observed overall, although the relationships between vitamin D pathway polymorphisms and breast cancer may be modified by menopausal status and breast tumour subtype.

  4. EB'95-97: Deep Lithospheric Structure of the East European Craton Beneath the EUROBRIDGE Seismic Transect

    Janik, T.

    2002-12-01

    During 1994-1997, a deep seismic sounding (DSS) experiment was conducted along a profile extending from the Baltic Sea to the Dniepr basin area . This cooperative effort is called EUROBRIDGE, and its purpose is to study the lithospheric structure of the East European Craton (EEC) between the Baltic and Ukrainian shields. Seismic data for this 1200 km long profile were acquired during two campaigns (EB'95&'96 and EB'97) in which about 120, 3-component seismographs were deployed at a station spacing of 3-4 km. The EB'95&'96 effort involved recording along a 700 km long NW-SE trending transect that crossed the EEC from the West Lithuanian Granulite belt to the Ukrainian shield. Sources were 24 explosive shots of up to 1000 kg in size and were detonated at intervals of about 30 km. In addition, a large shot was fired in the Baltic Sea close to Gotland Island. Tomographic inversion and ray trace modelling established a 2-D P-wave velocity model and spatial variations in Vp/Vs. The upper, middle and lower crystalline crust exhibit velocities of 6.1-6.3, 6.4-6.8 and 6.9-7.2 km/s. P-wave velocities immediately beneath Moho are 8.2-8.35 km/s. The crust below Lithuania is about 44 km thick, and below Belarus it is about 50 km thick. A lower lithosphere reflector occurs at 65-70 km depth. S-wave velocities are relatively high in the upper crust and low in the lower crust. Correlation of our seismic structure with near surface geology tentatively suggests that the contact zones between the East Lithuanian Belt, Belarus-Baltic Granulite Domain, Central Belarussian Belt, and the Osnitsk-Mikashevichi Igneous Belt all dip slightly to the southeast, consistent with the hypothesis of successive docking of these terranes during craton growth. The effort in 1997 (EB'97) involved recording along a 530 km long north-trending profile. This profile traverses the northwestern part of the Ukrainian shield within the Sarmatian province of the East European craton. Chemical explosions at 18

    The Palaeoproterozoic Ingul block occupies the central part of the Ukrainian Shield in the Sarmatian crustal segment of the East European Craton. It is situated between two groups of Archaean blocks, the Middle Dniepr and Azov blocks in the east, and the Podolian and Bug blocks, in the southwest. In the Archaean and the earliest Palaeoproterozoic these western and eastern Archaean blocks had different structural evolutions and thus most probably were separated by an ocean. The Ingul block appears to have been formed during the closure of that ocean. Structurally, the Ingul block is a part of an up to 200 km wide zone of NS-trending dextral strike-slip faults. It extends far to the south and to the north and is also marked by the Kherson-Smolensk transregional fault zone. Archaean and Palaeoproterozoic rock complexes occur at the margins of the Ingul block whereas its middle part is completely Palaeoproterozoic. Its formation began during the 2.1-2.05 Ga collisional closing of the assumed ocean and the docking of the Archaean eastern and western continental blocks with each other. It was accompanied by dextral strike-slip faulting and strong compression. As a result, the Golovanevsk and Ingulets-Krivoi Rog suture zones were formed along the edges of the Eastern and Western Sarmatian microplates. Between 2.05 and 1.75 Ga, intense tectonothermal reworking and strike-slip faulting took place in the Ingul block. Several phases of deformation have been recognized. These are: • At 2.05-2.0 Ga - the Kherson phase of extension (azimuth/dip angle of the tension axis σ3 278/10, the compression axis σ1 8/00, dextral strike-slip faulting) accompanied by the intrusion of the Novo-Ukrainka monzogranitoids and some anatectic granitoids, and the formation of the Kherson-Smolensk fault zone, • At 2.0-1.8 Ga - two subsequent phases of compression: (1) the Kirovograd phase (σ1 49/00, σ3 319/00) and the development of a system of dextral strike-slip faults in the central part

    This paper presents an integrated geophysical study of the southern margin of the East European Craton (EEC) in the Karpinksy Swell-North Caucasus area. It presents new interpretations of deep refraction and wide-angle reflection "deep seismic sounding" (DSS) data as well as conventional seismic and CDP profiling and new analyses of potential field data, including three-dimensional gravity and magnetic modelling. An integrated model of the physical properties and structure of the Earth's crust and, partially, upper mantle displays distinct features that are related to tectonic history of the study area. The Voronezh Massif (VM), the Ukrainian Shield and Rostov Dome (RD) of the EEC as well as the Donbas Foldbelt (DF), Karpinsky Swell (KS), Scythian Plate (SP) and Precaspian Basin (PCB) constitute the geodynamic ensemble that developed on the southern margin of the continent Baltica. There proposed evolutionary model comprises a stage of rifting during the middle to late Devonian, post-rift extension and subsidence during Carboniferous-early Permian times (synchronous with and related to the southward displacement of the Rostov Dome and extension in a palaeo-Scythian back-arc basin), and subsequent Mesozoic and younger evolution. A pre-Ordovician, possibly Riphean (?), mafic magmatic complex is inferred on a near vertical reflection seismic cross-section through the western portion of the Astrakhan Dome in the southwest part of the Precaspian Basin. This complex combined with evidence of a subducting slab in the upper mantle imply the presence of pre-Ordovician (Riphean?) island arc, with synchronous extension in a Precaspian back-arc basin is suggested. A middle Palaeozoic back-arc basin ensemble in what is now the western Karpinsky Swell was more than 100 km to the south from its present location. The Stavropol High migrated northwards, dislocating and moving fragments of this back-arc basin sometime thereafter. Linear positive magnetic anomalies reflect the

    We present a new 1-D P wave seismic velocity model (called MP1-SUW) of the upper mantle structure beneath the western rim of the East European Craton (EEC) based on the analysis of the earthquakes recorded at the Suwałki (SUW) seismic station located in NE Poland which belongs to the Polish Seismological Network (PLSN). Motivation for this study arises from the observation of a group of reflected waves after expected P410P at epicentral distances 2300-2800 km from the SUW station. Although the existing global models represent the first-arrival traveltimes, they do not represent the full wavefield with all reflected waves because they do not take into account the structural features occurring regionally such as 300 km discontinuity. We perform P wave traveltime analysis using 1-D and 2-D forward ray-tracing modelling for the distances of up to 3000 km. We analysed 249 natural seismic events from four azimuthal spans with epicentres in the western Mediterranean Sea region (WMSR), the Greece and Turkey region (GTR), the Caucasus region (CR) and the part of the northern Mid-Atlantic Ridge near the Jan Mayen Island (JMR). For all chosen regions, except the JMR group for which 2-D modelling was performed, we estimate a 1-D average velocity model which will characterize the main seismic discontinuities. It appears that a single 1-D model (MP1-SUW model) explains well the observed traveltimes for the analysed groups of events. Differences resulting from the different azimuth range of earthquakes are close to the assumed picking uncertainty. The MP1-SUW model documents the bottom of the asthenospheric low-velocity zone (LVZ) at the depth of 220 km, 335 km discontinuity and the zone with the reduction of P wave velocity atop 410 km discontinuity which is depressed to 440 km depth. The nature of the regionally occurring 300 km boundary is explained here by tracing the ancient subduction regime related to the closure of the Iapetus Ocean, the Rheic Ocean and the Tornquist Sea.

    The existing European Lysimeter Platform (www.lysimeter.at/HP_EuLP) provides an overview of lysimeter types used in Europe and show details on equipment, research results and future perspectives of lysimeter facilities. However, this platform is not user-editable and has not been updated since 2008. Thus, the Lysimeter Research Group (www.lysimeter.at) intends to serve a new database based website called Lysimeter Platform, where existing information of the former European Lysimeter Platform will be transferred to the new Lysimeter Platform and, furthermore, registered users are able to create and edit sites where lysimeters, soil water samplers and soil hydrologic measuring profiles are operated. The Lysimeter Research Group is a scientific association and, therefore, the membership is free of charge. The new Lysimeter Platform contains general information of lysimeter sites worldwide (e.g., what is measured at which site) in a standardized form to get a quick but informative overview of the sites and can be linked to more detailed, already existing information provided by the site operators. Due to the standardized information in the database the Lysimeter Platform serves also as search-engine for soil water measurements and helps to find sites of interest and corresponding contact information worldwide. The Session "Estimation of soil-atmosphere and vadose zone water fluxes by use of precision lysimeter measurements" at the EGU General Assembly 2014 would be an excellent chance to present the idea and the concept of this new Lysimeter Platform to international site operators and scientists.

    In water balance estimations within palaeoenvironmental studies river runoff is estimated as the difference between precipitation and evapotranspiration. The other technique is numerical modeling using general circulation models. Both approaches fail to recognize epochs of extremely high surface runoff characteristic for the Pleistocene cold epochs and recorded in geomorphic outcomes of this runoff. We have studied two kinds of such archives that have wide spatial coverage over the East European Plain (EEP). 1. Post-LGM large palaeochannels (macromeanders) in river valleys with channel width and meander wavelength 5-15 times as great as that of modern rivers. Massive measurements of their parameters and application of specially constructed transfer function provided estimations of palaeo-runoff from large river basins: in the Black Sea and Caspian Sea catchments it carried from 2.2 (Kama River) to 3.1 (Don, Dnieper Rivers) times as great as modern runoff. High runoff lasted long enough to provide formation of 2-3 generations of macromeanders characteristic for many valleys. Macromeanders were radiocarbon dated at 6 sites over EEP in the range 13-19 cal ka BP, but it is not clear whether high runoff was characteristic for the entire period or it performed during short isolated epochs within this interval. Therefore, it is not clear to what exact time palaeohydrological estimations should be attributed. 2. Dendritic and parallel systems of gentle hollows clearly designated in vegetation-free areas south from 55-57ºN. Distinctive spatial patterns and full integration into water transportation through modern fluvial landscapes provides interpretation of these hollow systems as partially or totally buried networks of small dry valleys (balkas). It is supported by revelation of buried incisions up to 10 m deep by coring and trenching across hollows. Ancient erosion network demonstrates erosion density much higher and Horton's "belt of no erosion" much narrower and

    The southern part of the eastern European continental landmass consists mainly of a thick platform of Vendian and younger sediments overlying Precambrian basement, part of the East European Craton (EEC). The Scythian Platform (SP) lies between the EEC and the (mainly Alpine) deformed belt running from Dobrudja (Romania) to Crimea (Ukraine) and the Greater Caucasus (Russia), along the northern margin of the Black Sea. Hard constraints on the Palaeozoic history on the SP are very sparse and little is known of its crustal structure in this area. The poster presents the seismic results of a multidisciplinary project that fills some of this gap. The project is called DOBRE-2 (as it forms a prolongation of the successful DOBRE project executed in 1999-2001). The main objectives of DOBRE-2 were to elucidate the deep-seated structure of the lithosphere and geodynamic setting of the shelf zones of the Azov and Black seas and the Crimean peninsula and to study the deep controls on the structure of basement and sedimentary cover. DOBRE-2 traverses a number of major faults and suture zones separating the EEC from the SP, the Crimean Mountains, and the Black Sea depression. Significant hydrocarbon reserves occur in the basins traversed by DOBRE-2. Deep seismic reflection profiling (30 second, Vibroseis) has been completed on a 100-km segment of the profile on the Azov massif (part of the Ukrainian Shield) as well as a 47-km segment in Crimea. These are complemented by refraction profiling on the shelf zones of the Azov (~53 km) and Black (~160 km) seas and coincident near-vertical (CDP) in the Black Sea, using a combination of onshore seismograph stations, ocean-bottom seismometers, onshore explosive energy sources (6 shot points), as well as ship-borne seismic acquisition. We present a 2-D seismic velocity model (Vp in the crust, depth to the Moho and depth to the intracrustal reflectors) along (~780 km) the DOBRE-2 & DOBRE'99 transect. Our model extends the model published

    Water-soluble organic compounds (WOCs) and their single components, i.e. low-molecular organic acids, alcohols, and carbohydrates, attain a great deal of attention among soil scientists. WOCs are an important component of soil organic matter (SOM) and form as a results of different biological and chemical processes in soils. These processes are mainly responsible for formation and development of soils in aboveground ecosystems. The purpose of the work was identifying qualitative and quantitative composition of low-molecular organic substances which form in podzolic loamy soils against natural reforestation after spruce forest cutting. The studies were conducted on the territory of the European North-East of Russia, in the middle taiga subzone (Komi Republic, Ust-Kulom region). The study materials were soil of undisturbed bilberry spruce forest (Sample Plot 1 (SP1)) and soils of different-aged tree stands where cutting activities took place in winter 2001/2002 (SP2) and 1969/1970 (SP3). Description of soils and vegetation cover on the plots is given in [1]. Low-molecular organic compounds in soil water extracts were identified by the method of gas chromatography mass-spectrometry [2, 3]. Finally, reforestationafterspruceforestcutting was found to be accompanied by different changes in soil chemical composition. In contrast with soils under undisturbed spruce forest, organic soil horizons under different-aged cuts decreased in organic carbon reserves and production of low-molecular organic compounds, changed in soil acidity. Within the soil series of SP1→SP2→SP3, the highest content of WOCs was identified for undisturbed spruce forest (738 mg kg-1 soil). In soils of coniferous-deciduous forests on SP1 and SP3, WOC content was 294 and 441 mg kg-1 soil, correspondingly. Soils at cuts decreased in concentration of any water-soluble low-molecular SOM components as low-molecular acids, alcohols, and carbohydrates. Structure of low-molecular WOCs in the study podzolic

    The Cook Islands are considered the "gateway" for human colonization of East Polynesia, the final chapter of Oceanic settlement and the last major region occupied on Earth. Indeed, East Polynesia witnessed the culmination of the greatest maritime migration in human history. Perennial debates have critiqued whether Oceanic settlement was purposeful or accidental, the timing and pathways of colonization, and the nature and extent of postcolonization voyaging-essential for small founding groups securing a lifeline between parent and daughter communities. Centering on the well-dated Tangatatau rockshelter, Mangaia, Southern Cook Islands, we charted the temporal duration and geographic spread of exotic stone adze materials-essential woodworking tools found throughout Polynesia- imported for more than 300 y beginning in the early AD 1300s. Using a technique requiring only 200 mg of sample for the geochemical analysis of trace elements and isotopes of fine-grained basalt adzes, we assigned all artifacts to an island or archipelago of origin. Adze material was identified from the chiefly complex on the Austral Islands, from the major adze quarry complex on Tutuila (Samoa), and from the Marquesas Islands more than 2,400 km distant. This interaction is the only dated example of down-the-line exchange in central East Polynesia where intermediate groups transferred commodities attesting to the interconnectedness and complexity of social relations fostered during postsettlement voyaging. For the Cook Islands, this exchange may have lasted into the 1600s, at least a century later than other East Polynesian archipelagos, suggesting that interarchipelago interaction contributed to the later development of social hierarchies.

    We report on the development, testing and deployment of the next generation of autonomous adaptive low-power instrument platforms (AAL-PIP) for use in remote Antarctic locations. Specifically, we are in the process of deploying a dense chain on the east Antarctic plateau along the 40 degree magnetic meridian. These stations are magnetically conjugate to the west coast of Greenland and enable us to investigate solar wind - magnetosphere - ionosphere coupling simultaneously in both polar regions. The Antarctic stations on this chain provide data from fluxgate and induction magnetometers, dual-frequency GPS receivers as well as a variety of engineering and environmental parameters. Two-way communication with the stations is achieved using the Iridium satellite system. This enables acquisition of the data and the ability to change the operational parameters of the data collection programs. The stations are solar powered with battery storage for winter operation. We will discuss the design, technical characteristics, and operation results. This research is supported by the National Science Foundation through a Major Research Infrastructure (MRI) grant ATM-922979 and a research grant ANT0839858.

    Jan de Vries engages with Osamu Saito's discussion of Tokugawa Japan, in particular, his exploration of de Vries's concept of an industrious revolution for East Asia, which was published in this journal in 2010. The discussion bears on the ongoing debate over the timing and character of the Great Divergence, when advanced parts of Europe pulled ahead of Asia. de Vries argues that the constraint on the Japanese rural household to acquire and shed labour delayed the shift from supply-side industriousness to demand-motivated industriousness, which in turn meant that the Great Divergence was already in place before 1800.

  18. Phylogeography of amphi-boreal fish: tracing the history of the Pacific herring Clupea pallasii in North-East European seas

    2013-01-01

    Background The relationships between North Atlantic and North Pacific faunas through times have been controlled by the variation of hydrographic circumstances in the intervening Arctic Ocean and Bering Strait. We address the history of trans-Arctic connections in a clade of amphi-boreal pelagic fishes using genealogical information from mitochondrial DNA sequence data. The Pacific and Atlantic herrings (Clupea pallasii and C. harengus) have basically vicarious distributions in the two oceans since pre-Pleistocene times. However, remote populations of C. pallasii are also present in the border waters of the North-East Atlantic in Europe. These populations show considerable regional and life history differentiation and have been recognized in subspecies classification. The chronology of the inter-oceanic invasions and genetic basis of the phenotypic structuring however remain unclear. Results The Atlantic and Pacific herrings both feature high mtDNA diversities (large long-term population sizes) in their native basins, but an ocean-wide homogeneity of C. harengus is contrasted by deep east-west Pacific subdivision within Pacific C. pallasii. The outpost populations of C. pallasii in NE Europe are identified as members of the western Pacific C. pallasii clade, with some retained inter-oceanic haplotype sharing. They have lost diversity in colonization bottlenecks, but have also thereafter accumulated abundant new variation. The data delineate three phylogeographic groups within the European C. pallasii: herring from the inner White Sea; herring from the Mezen and Chesha Bays; and a strongly bottlenecked peripheral population in Balsfjord of the Norwegian Sea. Conclusions The NE European outposts of C. pallasii are judged to be early post-glacial colonists from the NW Pacific. A strong regional substructure has evolved since that time, in contrast to the apparent broad-scale uniformity maintained by herrings in their native basins. The structure only partly matches the

    Introduction Comparing results of representative surveys conducted in different East-European countries could contribute to a better understanding and management of cardiovascular risk factors, offering grounds for the development of health policies addressing the special needs of this high cardiovascular risk region of Europe. The aim of this paper was to describe the methodology on which the comparison between the Romanian survey SEPHAR II and the Polish survey NATPOL 2011 results is based. Material and methods SEPHAR II, like NATPOL 2011, is a cross-sectional survey conducted on a representative sample of the adult Romanian population (18 to 80 years) and encompasses two visits with the following components: completing the study questionnaire, blood pressure and anthropometric measurements, and collection of blood and urine samples. Results From a total of 2223 subjects found at 2860 visited addresses, 2044 subjects gave written consent but only 1975 subjects had eligible data for the analysis, accounting for a response rate of 69.06%. Additionally we excluded 11 subjects who were 80 years of age (NATPOL 2011 included adult subjects up to 79 years). Therefore, the sample size included in the statistical analysis is 1964. It has similar age groups and gender structure as the Romanian population aged 18–79 years from the last census available at the moment of conducting the survey (weight adjustments for epidemiological analyses range from 0.48 to 8.7). Conclusions Sharing many similarities, the results of SEPHAR II and NATPOL 2011 surveys can be compared by a proper statistical method offering crucial information regarding cardiovascular risk factors in a high-cardiovascular risk European region.

    European sardine (Sardina pilchardus) and European anchovy (Engraulis encrasicolus) are two species of economical and ecological significance in the Bay of Biscay (north-east Atlantic). However, the trophic ecology of both species is still poorly known in the area, and more generally, few studies have considered the potential trophic overlap between sardines and anchovies worldwide. This study aims to highlight the trophic links between the mesozooplankton and adults of these two pelagic fish in the Bay of Biscay, through carbon and nitrogen stable isotope analysis (SIA). Mesozooplankton and individuals of sardines and anchovies were collected during one season (spring 2010), over spatially contrasted stations within the study area. First, the potential effect of preservation (ethanol vs. freezing) and of delipidation (by cyclohexane) on mesozooplankton δ13C and δ15N values was assessed. Results demonstrated the necessity to correct for the preservation effect and for lipid contents in mesozooplankton for further analyses of sardines' and anchovies' diet through SIA. Next, this study highlighted the interest of working on identified mesozooplanktonic organisms instead of undetermined assemblages when unravelling food sources of planktivorous fish using stable isotopes. The inter-specific variability of isotope values within a planktonic assemblage was effectively high, probably depending on the various feeding behaviours that can occur among mesozooplankton species. Intra-specific variability was also significant and related to the spatial variations of baseline signatures in the area. To investigate the foraging areas and potential diet overlap of S. pilchardus and E. encrasicolus, mixing models (SIAR) were applied. Both fish species appeared to feed mainly in the neritic waters of the Bay of Biscay in spring and to select mainly small- to medium-sized copepods (e.g. Acartia sp., Temora sp.). However, E. encrasicolus showed a greater trophic plasticity by

    The Divnogorie Nature Park is in the basin of the middle Don River. Tectonically, it sits on the Ostrogozhskoye Neotectonic Uplift, a recent extension of the northern wing of the Voronezh Anteclise of the Russian Platform. The neotectonic uplift amplitude of this structure is estimated at more than 200 m. A structural geomorphological study of the area has shown that the Ostrogozhskoye Uplift is an actively growing structure. This is clearly demonstrated by the following: dramatic changes in the flow direction of the rivers Don and Tikhaya Sosna, forced to bypass the growing upland; instances of damming up, which created numerous oxbow lakes and led to waterlogging in floodplains; increase in the density of the erosion grid on the upland; fall of the groundwater table (Romanovskaya, 2015). Uplifting has intensified erosion and slope wash processes, forming numerous canyon-shaped ravines, very steep slopes (>60º) and interconnected bastion-like relief forms. Superimposed on the geology of the area, neotectonic movements and erosion have led to the formation of a peculiar relief (chalk outliers), microclimate and ecosystem (petrophytic steppe). Surrounded by protections in the form of steep slopes and water courses, this area is a natural fortress which has favored human habitation since the Late Paleolithic Age. In a location in the Tikhaya Sosna river basin, gully erosion has exposed a large accumulation of ancient horse (Equus caballus) bones. Now this location (50.9649ºN, 39.3031ºE) is known as the Upper Paleolithic (13.5-14 kaBP) multi-level archaeological site Divnogorie-9. About 8,000 horse bones and 65 human-made stone artifacts have been discovered here in Late Pleistocene diluvial-alluvial-colluvial deposits (Kuznetsova, 2014). The mass die-off of wild horses and their reburial at the site are most probably the result of landscape and geological impact of massive temporary water flows that will be addressed in some detail in the actual presentation of

    Results are presented of a seismic wide-angle reflection/refraction survey along a profile between the Pannonian Basin (PB) and the East European Craton (EEC) called PANCAKE. The P- and S-wave velocity model derived can be divided into three sectors: the PB; the Carpathians, including the Transcarpathian Depression and the Carpathian Foredeep; and the south-western part of the EEC, including the Trans European Suture Zone (TESZ). Seismic data support a robust model of the Vp velocity structure of the crust. In the PB, the 22-23 km thick crust consists of a 2-5 km thick sedimentary layer (Vp = 2.4-3.7 km/s), 17-20 km thick upper crystalline crust (5.9-6.3 km/s) and an up to 3 km thick lower crustal layer (Vp = 6.4 km/s). In the central part of the Carpathians, a 10-24 km thick uppermost part of the crust with Vp ≤ 6.0 km/s may correspond to sedimentary rocks of different ages; several high velocity bodies (Vp = 5.35, 5.95 and 6.05 km/s) within the sedimentary flysch sequences may represent volcanic sequences. The Moho depth changes from 25 km to 45 km over ca. 100 km distance beneath the Carpathians, west of TESZ. The cratonic crust has a typical three layer structure with a pronounced thickening of the lower crust towards the Ukrainian Shield, where a high velocity lower crust (Vp > 7.2 km/s) is observed. Two low-velocity lenses in the upper crust of the EEC are interpreted beneath major sedimentary troughs (Lviv and Volyn-Podolsk). Mantle reflectors are observed at depths of ~ 45 km and ~ 75 km below the PB and 10-20 km below the Moho in the EEC. Sub-Moho (Pn) velocities increase from 8.0 km/s beneath the PB to 8.1 km/s beneath the Carpathians and to ~ 8.3 km/s beneath the EEC. S-waves of acceptable quality are recorded in the EEC; their signal-to-noise ratios increase towards the Ukrainian Shield.

    A southwestward younging of Palaeoproterozoic terranes in the crystalline basement in the western part of the East European Craton has been recently suggested by numerous isotopic datings (TIMS, SIMS zircon, EPMA monazite and 40Ar/39Ar). Along with geochemical and geophysical data this allows to decipher a multistage accretionary history. In the east, the Belarus-Podlasie Granulite belt (BPG) is dominated by 1.88 Ga dioritic-granodioritic (calc-alkaline) magmatism in Belarus (Claesson et al., 2001). Remnants of c. 1.89 Ga metadiorites, c. 1.90 Ga magmatic zircon cores in c. 1.80 Ga granites (Vejelyte, 2011) in S and E Lithuania and 1.88 Ga metagranodiorites in E Poland (Radzyn area) confirm the c. 1.90 Ga accretion-related magmatism in the BPG and the East Lithuanian domain. Together with the coeval juvenile granitoids in the adjacent Okolovo terrane this indicates the formation of the Lithuanian-Belarus composite terrane at 1.90-1.88 Ga. At c. 1.86-1.84 Ga, abundant gabbro-diorite-granodiorite-granite intrusions were emplaced further southwest in Lithuania, NW Belarus and N Poland. In Lithuana, within the Polish-Lithuanian terrane the TTG suite of deformed and metamorphosed in amphibolite facies calc-alkaline tonalitic, quartz dioritic and dioritic rocks is characteristic for the Randamonys massif. The strongly deformed granitoids in the adjacent NW Belarus, mafic granulites and gneissic granites of igneous origin in central Lithuania, garnet-cordierite bearing granites further north display similar c. 1.84 Ga magmatic age (Motuza et al., 2008). This shows that various tectonic settings including island and continental magmatic arcs were possible. They were accreted to the Lithuanian-Belarus terrane sometime at 1.84-1.81 Ga while voluminous charnockitic magmatism took place in W Lithuania (e.g. Claesson et al., 2001; Vejelyte, 2011). A chain of younger c. 1.83 Ga volcanic arcs was developed in W and S Lithuania and N Poland (Wiszniewska et al., 2005). The

    The present study was undertaken with the objective of deriving constraints from available geological and geophysical data for understanding the tectonic setting and processes controlling the evolution of the southern margin of the East European Craton (EEC). The study area includes the inverted southernmost part of the intracratonic Dnieper-Donets Basin (DDB)-Donbas Foldbelt (DF), its southeastern prolongation along the margin of the EEC-the sedimentary succession of the Karpinsky Swell (KS), the southwestern part of the Peri-Caspian Basin (PCB), and the Scythian Plate (SP). These structures are adjacent to a zone, along which the crust was reworked and/or accreted to the EEC since the late Palaeozoic. In the Bouguer gravity field, the southern margin of the EEC is marked by an arc of gravity highs, correlating with uplifted Palaeozoic rocks covered by thin Mesozoic and younger sediments. A three-dimensional (3D) gravity analysis has been carried out to investigate further the crustal structure of this area. The sedimentary succession has been modelled as two heterogeneous layers—Mesozoic-Cenozoic and Palaeozoic—in the analysis. The base of the sedimentary succession (top of the crystalline Precambrian basement) lies at a depth up to 22 km in the PCB and DF-KS areas. The residual gravity field, obtained by subtracting the gravitational effect of the sedimentary succession from the observed gravity field, reveals a distinct elongate zone of positive anomalies along the axis of the DF-KS with amplitudes of 100-140 mGal and an anomaly of 180 mGal in the PCB. These anomalies are interpreted to reflect a heterogeneous lithosphere structure below the supracrustal, sedimentary layers: i.e., Moho topography and/or the existence of high-density material in the crystalline crust and uppermost mantle. Previously published data support the existence of a high-density body in the crystalline crust along the DDB axis, including the DF, caused by an intrusion of mafic and

    The Sura-Kama zone (SKZ) complicates the central area of the Volga-Ural anteclise and extends sublaterally from the Sura River basin towards the Kama River at a distance of 700-750 km. Based on the analysis of geological-geophysical data and structural studies, a model for the tectonic structure and the evolution of the SKZ is developed. This is a deep tectonic fault that shows the features of long-term polystage development. During the latest Cimmerian-Alpine period of tectonic reactivation, the SKZ represented a zone of strike-slip and consecutive manifestation of early transpressional right-lateral strike-slip dislocations that changed to left-lateral strike-slip displacements under transtension settings as a result of kinematic inversion. Features of the heterogeneous structure of the SKZ are revealed. The segments formed by the system of strike-slip duplexes are alternated along the strike by the principle of rotation-fold and "domino" structures. The particular models of evolution of these segments are proposed by the examples of the widely known Karlin, Tetyushin, and Lower Kama dislocations. It is assumed that kinematic inversion and compression-decompression phenomena on the flanks of the SKZ, as well as the tectonic environments in the area of its dynamic influence were highly important for the development of the processes of migration and redistribution of hydrocarbon components.

  7. Within-plate magmatism under condition of abnormally thick sialic crust: Evidence for Proterozoic anorthosite-rapakivi granite complexes of the East-European Craton

    2010-05-01

    Mid-Proterozoic (1.8-1.5 Ga) large bimodal multistage anorthosite-rapakivi granite complexes (ARGCs) are distinct magmatic assemblages in central part of the East European Craton. ARGCs formation commenced after stabilization of the Svecofennian orogen and relics of its abnormally thick (up to 50-60 km now) crust survived here in many places. Such massifs are practically absent at the eastern part of the craton (Kola-Karelian, Volga-Urals, etc. domains) with normal thickness (~40 km) of the crust. The ARGCs formation was accompanied by emplacement of diabase, quartz porphyry and complex dike swarms. Intra-plutonic diabase dikes (Fe-Ti basalts plume-related type), intruding the rapakivi granites, are often crossed in turn by later portions of granites; injections of basaltic melt into granitic magma chambers resulted in magma mingling. It indicates that melted out occurred simultaneously in mantle and crust during ARGC formation. Geochemical peculiarities of the ARGC rocks are enrichment in alkali (especially in K), Ti, Zn, Pb, and Zr, relatively high concentrations of Be, Sn, In, Y, Nb, Rb, F, Cu, W and Mo, and sometimes - Li and U. ɛNd value, ranges from -1.2 to +1.6, and relative high Th and Zn contents, most frequently observable in anorthosites, imply that the mafic magmas were considerably contaminated by crustal components. According to geophysical data, ARGCs represent upper parts of large transcrustal systems, composed by alternation of basic and silicic rocks, which located above rises of the mantle up to 10-20 km high. Such localization of ARGCs, probably evidence that such protuberances were mantle plume heads in time, where melting of their material occurred due to adiabatic decompression. Newly-formed basaltic melts (apparently Fe-Ti basalts, similar in composition to intra-plutonic dike rocks) intruded at different depths into abnormally thick sialic crust of stabilized by then Svecofennian orogen in form of large sills and caused melting of crustal

    The comprehensive analysis of the data obtained on terrestrial vertebrata, ostracods, entomologic fauna, megaflora, and microflora in deposits of the Vyaznikovian Horizon and Nedubrovo Member, as well as the paleomagnetic data measured in enclosing rocks, confirms heterogeneity of these deposits. Accordingly, it is necessary to distinguish these two stratons in the terminal Permian of the East European Platform. The combined sequence of Triassic-Permian boundary deposits in the Moscow Syneclise, which is considered to be the most complete sequence in the East European Platform, is as follows (from bottom upward): Vyatkian deposits; Vyaznikovian Horizon, including Sokovka and Zhukovo members; Nedubrovo Member (Upper Permian); Astashikha and Ryabi members of the Vokhmian Horizon (Lower Triassic). None of the sequences of Permian-Triassic boundary deposits known in the area of study characterizes this sequence in full volume. In the north, the Triassic deposits are underlain by the Nedubrovo Member; in the south (the Klyazma River basin), the sections are underlain by the Vyaznikovian Horizon. The Permian-Triassic boundary adopted in the General Stratigraphic Scale of Russia for continental deposits of the East European platform (the lower boundary of the Astashikha Member) is more ancient than the one adopted in the International Stratigraphic Chart. The same geological situation is observed in the German Basin and other localities where Triassic continental deposits are developed. The ways of solving this problem are discussed in this article.

    The western East European Craton (EEC) was formed by the accretion of distinct terrains at c. 1.8 Ga. Some boundaries between particular terrains and their continuation across the Baltic Sea from Lithuania to Sweden have to be justified. Recently obtained numerous U-Pb zircon ages from the Siupariai 3 (Sp3), Palukne 1 (Pl1) charnockites, Rukai 1 (Rk1), Geluva 99 (Gl99) granitoids, Bliudziai 150 (Bl150), Lauksargiai (Lk2, 5) and Pociai 3(Pc3) granulites determined using a Cameca ims1270 instrument of the Nordic high-resolution ion-microprobe facility (NORDSIM), as well as monazites of the Sp3, Pl1, Vydmantai 1 (Vd1) charnockites, Lk2, 5, Bl150 granulites dated by Cameca SX-100 electron microprobe (EPMA dating) at University of Warsaw allowed to reconstruct terrain boundaries from north to south in western Lithuania and a sequence of crust-forming events. In the north, the slightly deformed, coarse-grained Sp3, Pl1 and Vd1 (Claesson et al., 2001) charnockitoids crystallized in the time span of c. 1.84-1.81 Ga. The magmatic zircons contain a few c. 2.4-2.0 Ga inherited cores. The rocks were deformed and thermally reworked immediately after their crystallization as indicated by c. 1.79-1.74 Ga zircons and c. 1.85-1.76 Ga high-Y monazites, but the major metamorphism they underwent not earlier than c. 1.70 Ga. Thick zircon rims and rounded sector-zoned metamorphic zircons of c. 1.70 Ga likely grew together with peak garnet at 800o C, 7 kbar (Sp3) or 760o C and 6.5 kbar (Pl1). Numerous 1.62-1.56 Ga monazites recorded decompression to 2 kbar and cooling to 500o C in Sp3, mostly cooling to 450o C (at 4 kbar) in Pl1, and isothermal decompression from 650o C at 7 kbar to 500o C at 3 kbar in Vd1. In the south, the Bl150, Lk2, 5 and Pc 3 metasedimentary granulites containing a wide age range (3.0 to 1.85 Ga) of detrital zircons were deposited not earlier than 1.89 Ga. An incipient metamorphism started with the growth of relatively high-Y monazite (Y>3%) at 1.84-1.83 Ga, however

  14. European and Middle-East ferroan hydrothermal dolomites: lessons learnt with respect to crustal dynamics, fluid circulations and rock-fluid interactions

    NASA Astrophysics Data System (ADS)

    2016-04-01

    Classical case studies of hydrothermal dolostones, which are known worldwide to provide excellent reservoirs for ores and hydrocarbons, often illustrate the presence of iron-rich dolomite phases. The world-class hydrothermal dolostones from the Basque-Cantabrian Basin (Northern Spain) exemplify the initiation of high temperature dolomitization (at about 200°C), with significant amount of ferroan dolomite phases (including up to 2% FeO). These dolomites are believed to be responsible for the pervasive replacement of the original limestone rocks - they are followed by non-ferroan dolomite phases. The associated fluids are supposed to have interacted with basement rocks, and travelled from deep-seated sources along major fault pathways. The geochemical traits of such fluids are also typically similar to, and probably associated with, mineralization fluids (e.g. Pb-Zn, MVT). In the Middle East, several observed dolostones show, on the contrary, a later phase of ferroan dolomite cements which occlude the inter-crystalline porosity of earlier non-ferroan matrix dolomites. Dolomitization occurred under increasingly higher temperatures (from 50 to 100°C) during burial. Here, the origin of iron-rich fluids and conditions of precipitation of associated dolomites do not necessarily involve interactions with basement rocks, but rather a relative Fe-enrichment with further reducing settings. Based on previous research projects concerning a variety of dolostones from Europe and the Middle-East, this contribution presents observational, analytical and computational results focused on ferroan dolomites. Recent numerical geochemical modelling emphasized the physico-chemical pre-requisites for crystallizing ferroan rather than non-ferroan dolomites (and vice-versa), allowing better understanding of related diagenetic processes. Besides, important larger-scale information on the crustal fluid circulations are demonstrated to be intimately associated to the parent-fluids sources and

  17. The added value of dynamical downscaling in a climate change scenario simulation:A case study for European Alps and East Asia

    Since anthropogenic climate change is a rather important factor for the future human life all over the planet and its effects are not globally uniform, climate information at regional or local scales become more and more important for an accurate assessment of the potential impact of climate change on societies and ecosystems. High resolution information with suitably fine-scale for resolving complex geographical features could be a critical factor for successful linkage between climate models and impact assessment studies. However, scale mismatch between them still remains major problem. One method for overcoming the resolution limitations of global climate models and for adding regional details to coarse-grid global projections is to use dynamical downscaling by means of a regional climate model. In this study, the ECHAM5/MPI-OM (1.875 degree) A1B scenario simulation has been dynamically downscaled by using two different approaches within the framework of RegCM3 modeling system. First, a mosaic-type parameterization of subgrid-scale topography and land use (Sub-BATS) is applied over the European Alpine region. The Sub-BATS system is composed of 15 km coarse-grid cell and 3 km sub-grid cell. Second, we developed the RegCM3 one-way double-nested system, with the mother domain encompassing the eastern regions of Asia at 60 km grid spacing and the nested domain covering the Korean Peninsula at 20 km grid spacing. By comparing the regional climate model output and the driving global model ECHAM5/MPI-OM output, it is possible to estimate the added value of physically-based dynamical downscaling when for example impact studies at hydrological scale are performed.

    We present the results of isotope-geochronological study of metasedimentary rocks of the Bolshecheremshanskaya Formation of the Volgo-Uralian segment of the East European Craton carried out to identify their protoliths. 16 samples of high-alumina gneisses from well cores were studied using the Sm-Nd isotope method and TNd(DM) model ages. Accessory zircons were selected from rocks with the most ancient model ages (more 3.2 Ga) in three wells: Minnibaevskaya 20000, Novo-Elkhovskaya 20009, and Zai-Karatayskaya 12930 in South Tatarstan. The isotope U-Pb dating of 200 zircon grains was performed on a Cameca 1280 NORDSIM secondary ion mass spectrometer at the Natural History Museum (Stockholm, Sweden). The most applicable sites for analysis of zircon crystals were pre-selected based on cathodoluminescence images. The analytical results demonstrate the diversity of zircon groups in age from 3.8 to 2.6 Ga and together with geochemical features of metasedimentary rocks of the Bolshecheremshanskaya Formation suggest the heterogeneous composition and age of provenance areas under denudation. Occurrence of Eoarchean and Paleoarchean zircons in the clastic material of the protolith of the Bolshecheremshanskaya gneisses indicates the existence of Early Archean crustal terrains in Volgo-Uralia.

Petroleum has been generated and has accumulated in Precambrian rifts beneath the sedimentary basins and, more importantly, within the section of the basin itself. The platformal deposits of the basins extend beneath overthrusts on the east and south and are covered by sedimentary rocks of the West Siberian province on the west. Permafrost and gas hydrate deposits are present throughout most of East Siberia. The hydrocarbon habitat of the three provinces is described. -from Author

    The Geohazards Exploitation Platform, or Geohazards TEP (GEP), is an ESA originated R&D activity of the EO ground segment to demonstrate the benefit of new technologies for large scale processing of EO data. This encompasses on-demand processing for specific user needs, systematic processing to address common information needs of the geohazards community, and integration of newly developed processors for scientists and other expert users. The platform supports the geohazards community's objectives as defined in the context of the International Forum on Satellite EO and Geohazards organised by ESA and GEO in Santorini in 2012. The GEP is a follow on to the Supersites Exploitation Platform (SSEP) an ESA initiative to support the Geohazards Supersites & Natural Laboratories initiative (GSNL). Today the GEP allows to exploit 70+ Terabyte of ERS and ENVISAT archive and the Copernicus Sentinel-1 data available on line. The platform has already engaged 22 European early adopters in a validation activity initiated in March 2015. Since September, this validation has reached 29 single user projects. Each project is concerned with either integrating an application, running on demand processing or systematically generating a product collection using an application available in the platform. The users primarily include 15 geoscience centres and universities based in Europe: British Geological Survey (UK), University of Leeds (UK), University College London (UK), ETH University of Zurich (CH), INGV (IT), CNR-IREA and CNR-IRPI (IT), University of L'Aquila (IT), NOA (GR), Univ. Blaise Pascal & CNRS (FR), Ecole Normale Supérieure (FR), ISTERRE / University of Grenoble-Alpes (FR). In addition, there are users from Africa and North America with the University of Rabat (MA) and the University of Miami (US). Furthermore two space agencies and four private companies are involved: the German Space Research Centre DLR (DE), the European Space Agency (ESA), Altamira Information (ES

  18. Microgravity Platforms

    NASA Technical Reports Server (NTRS)

    2000-01-01

    The world's space agencies have been conducting microgravity research since the beginning of space flight. Initially driven by the need to understand the impact of less than- earth gravity physics on manned space flight, microgravity research has evolved into a broad class of scientific experimentation that utilizes extreme low acceleration environments. The U.S. NASA microgravity research program supports both basic and applied research in five key areas: biotechnology - focusing on macro-molecular crystal growth as well as the use of the unique space environment to assemble and grow mammalian tissue; combustion science - focusing on the process of ignition, flame propagation, and extinction of gaseous, liquid, and solid fuels; fluid physics - including aspects of fluid dynamics and transport phenomena; fundamental physics - including the study of critical phenomena, low-temperature, atomic, and gravitational physics; and materials science - including electronic and photonic materials, glasses and ceramics, polymers, and metals and alloys. Similar activities prevail within the Chinese, European, Japanese, and Russian agencies with participation from additional international organizations as well. While scientific research remains the principal objective behind these program, all hope to drive toward commercialization to sustain a long range infrastructure which .benefits the national technology and economy. In the 1997 International Space Station Commercialization Study, conducted by the Potomac Institute for Policy Studies, some viable microgravity commercial ventures were identified, however, none appeared sufficiently robust to privately fund space access at that time. Thus, government funded micro gravity research continues on an evolutionary path with revolutionary potential.

    This paper is the review of the Consensus Document on Intermittent Claudication of the Central European Vascular Forum (CEVF), published in 2008, and and shared with the North Africa and Middle East Chapter of International Union of Angiology and the Mediterranean League of Angiology and Vascular Surgery. The Document presents suggestions for general practitioners and vascular specialists for more precise and appropriate management of PAD, particularly of intermittent claudication, and underlines the investigations that should be required by GPs and what the GP should expect from the vascular specialist (angiologist, vascular surgeon). The idea of the Faculty is to produce a short document, which is an easy reference in daily clinical practice, both for the GPs and vascular specialists. PMID:25056165

  2. Tectonic structure of East Antarctica

    2013-04-01

    First overviews of tectonic structure of the Southern Continent were made by the pioneers of Antarctic earth science investigations almost 100 years ago. Despite rapidly advancing international geological studies under the Antarctic Treaty, the presentations of Antarctic tectonic structure remained largely speculative until the end of the past century when implementation of modern analytical and remote-sensing research technologies enabled compilation of more credible tectonic models of Antarctica. The East Antarctic bedrock consists mainly of the Precambrian crystalline complexes and the Paleozoic-Early Mesozoic platform units. Crystalline Shield is locally complicated by Neoproterozoic aulacogenes and Late Paleozoic to Mesozoic rifts. Shield assemblages reliably recognized in coastal outcrops indicate the predominant occurrence of Archean cratonic nuclei and Mesoproterozoic mobile belts. The undisturbed platform cover strata are exposed in East Antarctica mainly along its boundary with West Antarctica. Tectonic structure of ice-covered regions (more that 99% of the East Antarctic territory) is interpreted using mostly magnetic and bedrock topography data, but other geophysical and geological information (satellite, airborne and over-ice gravity; seismology; active seismics; erratics; detrital zircons dates; etc.) is also important. Archean cratons are geologically documented in western Dronning Maud Land, Enderby Land, Princess Elizabeth Land and in the southern Prince Charles Mts. Their distribution under the ice is marked by a specific magnetic pattern including low-amplitude mosaic and/or high-amplitude long-wavelength anomalies. The most extensive ancient craton being 1000 km across is believed to extend from the southern Prince Charles Mts. to the Gamburtsev Mts. Mesoproterozoic mobile belts are distinguished by elongated high-amplitude magnetic anomalies and are mapped along the costal area as the zone of 250-600 km wide. The Gamburtsev Mts. area is also

    The European Community was established in 1951 to reconcile France and Germany after World War II and to make possible the eventual federation of Europe. By 1986, there were 12 member countries: France, Italy, Belgium, the Federal Republic of Germany, Luxembourg, the Netherlands, Denmark, Ireland, the United Kingdom, Greece, Spain, and Portugal. Principal areas of concern are internal and external trade, agriculture, monetary coordination, fisheries, common industrial and commercial policies, assistance, science and research, and common social and regional policies. The European Community has a budget of US$34.035 billion/year, funded by customs duties and 1.4% of each member's value-added tax. The treaties establishing the European Community call for members to form a common market, a common customs tariff, and common agricultural, transport, economic, and nuclear policies. Major European Community institutions include the Commission, Council of Ministers, European Parliament, Court of Justice, and Economic and Social Committee. The Community is the world's largest trading unit, accounting for 15% of world trade. The 2 main goals of the Community's industrial policy are to create an open internal market and to promote technological innovation in order to improve international competitiveness. The European Community aims to contribute to the economic and social development of Third World countries as well. PMID:12177941

  5. Why Does Mantle Downwelling Occur Beneath the South-east Carpathians?

    NASA Astrophysics Data System (ADS)

    Houseman, G. A.; Lorinczi, P.

    2011-12-01

    The Southeast Carpathian region of Romania provides one of the clearest examples of active mantle downwelling occurring beneath the continental lithosphere. Analysis of historical seismicity shows that seismically fast material in the upper 200 km beneath the Vrancea region of Romania is being stretched vertically; strains of order 100% requiring only a few million years. This deformation field is clearly not driven by surface convergence, because subduction ceased before 10 Ma and surface convergence since then has been minor under the persisting influence of the continuing collision between Adria and Europe. The depth distribution of deformation rate is explained, however, by a rapidly developing drip-like gravitational instability. Why has downwelling occurred in this location? We argue that deformation is localized here because the south-east corner of the Carpathians is caught in a pincer movement by convergence of the Moesian Platform and the East-European platform, that convergence being driven by the indentation of the Adriatic block into the European foreland. Because this type of gravitational instability is inferred to develop quickly relative to the characteristic time scale of thermal diffusion it can be represented as a type of Rayleigh-Taylor instability. We have carried out numerical experiments which simulate the development of Rayleigh-Taylor instability under this type of loading using Lagrangian-frame finite deformation calculations in 3D. Our experiments show that pre-existing structure in the form of lithospheric strength variations strongly determines how and where lithospheric downwelling develops. Variations in the effective viscosity of continental lithosphere due to temperature or composition may therefore be essential in explaining the exceptional development of this important tectonic process. While the tectonic forcing in conjunction with the pre-existing structure appear to be essential in determining the location and geometry (axial

    Recycling in the European Union (EU) has benefited from R&D efforts and strict environmental regulations of the EU’s members. Thanks to the adoption of sustainable development policies by the EU’s European Institutions, economic incentives are expected to further strengthen the recycling industry. Moreover, the historical accumulation of non-ferrous metals in Europe will likely enhance secondary metal production. Also contributing to EU recycling is mining in East European countries and the resulting industrial waste. The rate of growth of the recycling industry is expected to approach double digits for at least this decade.

    1994-03-01

    East Siberia comprises three petroleum provinces - Lena-Tunguska, Lena-Vilyuy, and Yenisey-Anabar - that occupy the area of the Siberian craton. Petroleum has been generated and has accumulated in Precambrian rifts beneath the sedimentary basins and, more importantly, within the section of the basin itself. The platformal deposits of the basins extend beneath overthrusts on the east and south and are covered by sedimentary rocks of the West Siberian province on the west. Permafrost and gas hydrate deposits are present throughout most of East Siberia. In the Lena-Tunguska province, rifts that developed during Riphean time are filled by thick sedimentary rocks, in which petroleum deposits have formed. In Early Cambrian time a barrier reef extended across the East Siberian craton from southeast to northwest. A lagoon to the west of this reef was the site of thick rhythmic salt deposits, which are the main seals for petroleum in the province. The sedimentary sections of the platform cover ranges in age from Late Proterozoic to Permian. More than 25 oil and gas fields have been discovered in the province, all in Riphean through Lower Cambrian rocks. 17 refs., 7 figs.

    The relative contributions to modern European populations of Paleolithic hunter-gatherers and Neolithic farmers from the Near East have been intensely debated. Haplogroup R1b1b2 (R-M269) is the commonest European Y-chromosomal lineage, increasing in frequency from east to west, and carried by 110 million European men. Previous studies suggested a Paleolithic origin, but here we show that the geographical distribution of its microsatellite diversity is best explained by spread from a single source in the Near East via Anatolia during the Neolithic. Taken with evidence on the origins of other haplogroups, this indicates that most European Y chromosomes originate in the Neolithic expansion. This reinterpretation makes Europe a prime example of how technological and cultural change is linked with the expansion of a Y-chromosomal lineage, and the contrast of this pattern with that shown by maternally inherited mitochondrial DNA suggests a unique role for males in the transition.

    Hispasat Advanced Generation 1 (HAG1) is the first satellite using the SGEO platform, which is under the development in the ESA Artes-11 program. Since the last presentation in the IAC 2007, a European industrial consortium led by OHB has completed the mission and spacecraft design. The platform Preliminary Design Review has been carried out in May 2008. The customer for the first mission is a commercial operator—Hispasat. The contract was signed in December 2008 and the satellite will be launched in 2012. To give confidence to the customer, SGEO platform will use up to date flight proven technologies. HAG1 carries 20/24 Ku-band and 3/5 Ka-band transponders to provide commercial services. Some innovative payload technologies will also be flown on board of HAG1 to gain in-orbit heritage. SGEO has also been selected as the baseline platform for the ESA Data Relay Satellite (EDRS). Phase-A study has just kicked off in January 2009. The targeted launch date is 2013. Heinrich Hertz will also use the SGEO platform. Heinrich Hertz is funded by the German Space Agency (DLR) and provides flight opportunities for technologies and components developed by the German Space Industry. With the HAG1 contract in hand, and EDRS and Heinrich Hertz in the line, OHB with its partners has the confidence that it will be able to speed up the product development of the SGEO platform for potential customers in the commercial market. This paper will first present the updated platform design and the status of the product development will be followed with the introduction of innovative payload technologies on board the first mission—HAG1 and ended with the mission concepts of EDRS and Heinrich Hertz missions.

During the Cambrian, a barrier reef extended across the region. Salt and anhydrite were deposited in the vast lagoon to the southwest behind this reef. The structure is typical of platforms; broad, gentle warps are complicated by smaller highs. The total area of East Siberia that is potentially favorable for oil and gas is 3.23 million km/sup 2/ (1.24 million mi/sup 2/). Deposits in the Lena-Tunguska province are in stratigraphic traps in Proterozoic to Cambrian clastic and carbonate sediments sealed by Cambrian salt and in anticlinal structures in areas of salt tectonics. Source beds seem to be Proterozoic. Pools in the Khatanga-Vilyuy province are in anticlines in Triassic, Jurassic, and Cretaceous clastic sedimentary rocks. Source beds are Permian carbonaceous shale. Most discoveries have been of gas; however, several fields have oil rings. The traps appear to have been filled by oil at one time. Undiscovered recoverable petroleum resources of East Siberia are assessed, at 90% probability, within the range of 2.2-14.6 billion bbl of oil and 72-278 tcf of gas. Mean estimates are 7.3 billion bbl of oil and 158 tcf of gas, respectively. Gas-hydrate deposits in the Lena-Vilyuy province, where permafrost is more than 400 m thick, are estimated to contain 27 tcf of possibly recoverable gas.

    1994-06-01

    This paper presents the concepts for a new family of wheeled platforms which feature full omnidirectionality with simultaneous and independently controlled rotational and translational motion capabilities. The authors first present the orthogonal-wheels concept and the two major wheel assemblies on which these platforms are based. They then describe how a combination of these assemblies with appropriate control can be used to generate an omnidirectional capability for mobile robot platforms. The design and control of two prototype platforms are then presented and their respective characteristics with respect to rotational and translational motion control are discussed.

    Earthquakes represent one of the world's most significant hazards in terms both of loss of life and damages. In the first decade of the 21st century, earthquakes accounted for 60 percent of fatalities from natural disasters, according to the United Nations International Strategy for Disaster Reduction (UNISDR). To support mitigation activities designed to assess and reduce risks and improve response in emergency situations, satellite EO can be used to provide a broad range of geo-information services. This includes for instance crustal block boundary mapping to better characterize active faults, strain rate mapping to assess how rapidly faults are deforming, soil vulnerability mapping to help estimate how the soil is behaving in reaction to seismic phenomena, geo-information to assess the extent and intensity of the earthquake impact on man-made structures and formulate assumptions on the evolution of the seismic sequence, i.e. where local aftershocks or future main shocks (on nearby faults) are most likely to occur. In May 2012, the European Space Agency and the GEO Secretariat convened the International Forum on Satellite EO for Geohazards now known as the Santorini Conference. The event was the continuation of a series of international workshops such as those organized by the Geohazards Theme of the Integrated Global Observing Strategy Partnership. In Santorini the seismic community has set out a vision of the EO contribution to an operational global seismic risk program, which lead to the Geohazard Supersites and Natural Laboratories (GSNL) initiative. The initial contribution of ESA to suuport the GSNL was the first Supersites Exploitation Platform (SSEP) system in the framework of Grid Processing On Demand (GPOD), now followed by the Geohazard Exploitation Platform (GEP). In this presentation, we will describe the contribution of the GEP for exploiting satellite EO for geohazard risk assessment. It is supporting the GEO Supersites and has been further

    The floating production platforms operating in the North Sea are adapted from drilling semisubmersibles which allow only a limited payload capacity. Experience of concrete production platforms constructed for the North Sea has led Sea Tank Co. to propose a floating platform which offers large payload and oil storage capacities similar to those of existing fixed platforms. Sea Tank Co. and Institut Francais du Petrole joined forces in early 1976 to study the feasibility of a concrete floating production platform incorporating the structure and the production riser together. The results of this 3-yr program show that the concrete floating structure is economically attractive for permanent utilization on a production site. Furthermore, concrete has definite advantages over other materials, in its long term behavior.

    In an earlier paper we proposed, on the basis of mitochondrial control region variation, that the bulk of modern European mitochondrial DNA(mtDNA) diversity had its roots in the European Upper Palaeolithic. Refining the mtDNA phylogeny and enlarging the sample size both within Europe and the Middle East still support this interpretation and indicate three separate phases of colonization: (i) the Early Upper Palaeolithic about 50,000 BP; (ii) the Late Upper Palaeolithic 11,000-14,000 BP; and (iii) the Neolithic from 8500 BP.

  14. New prospects in Cambrian platform orthoquartzites in Poland

    Middle Cambrian orthoquartzites produce oil in two small fields northwest of Gdansk, Poland; few developed offshore discoveries exist in the southeastern Baltic Sea. This joint Polish-German study on these poorly porous sandstones is aimed at delineating areas of better reservoir quality development and thus of future prospects. In the Polish part of the East European platform, Cambrian deposits exist in four geologic provinces (Lublin slope, Podiassle depression, Warsaw synclinorium, Baltic syneclise). In these areas, the Cambrian, which in part is more than 500 m thick, has been buried to depths between 300 and approximately 6000 m. The Middle Cambrian orthoquartzitic sandstones represent a shallow-marine sequences with interbedded claystones. Their porosities range form 2 to 8%, and oil production is improved by natural fractures. A major source rock for the oil accumulations is represented by Upper Cambrian black shales (TOC values, 3-13%; thickness approximately 1-10 m in northern onshore Baltic syneclise, up to 50 m in southern Scania, Sweden). The Middle Cambrian shales show low TOC contents (average, 0.3-0.6%) and a thickness of approximately 200 m. Despite their low organic content, they also could have been contributed to the reservoired oil because both black shales show maturities within the oil window and both contain an oil-prone algal kerogen. Therefore, in the northeast Polish oil province the restricted pore volume of the orthoquartzites and not the source rock parameters represents the major limiting factor for larger oil accumulations. Future prospects will be difficult to predict because the occurrence of traps might be much more controlled by diagenesis than by (tectonic) structures.

    1993-05-01

    Data from Hurricane Andrew demonstrated that the systems and procedures in place for evacuating offshore workers and minimizing oil spills and environmental damage functioned as planned. While the vast majority of the platforms survived the storm with no damage, a few of the older platforms (installed prior to 1972) either collapsed or suffered severe damage. The collapsed platforms were designed with insufficient deck height to clear the storm waves. In recent years, the API RP 2A has introduced guidance for minimum air gap, minimum structures, platform inspection and platform reuse. These provisions, coupled with natural attribution of the older platforms, will significantly improve the performance of platforms in the future. The reliability of NDT techniques to detect major structural defects should be improved through continued research. While flooded member detection is used by several operators as a screening tool to detect major defects underwater, its reliability is not always good and further research is needed in this area. Another area of high priority research is related to the use of Remotely Operated Vehicles (ROV) to perform underwater inspection of structures. 51 refs., 7 figs.

    There are over 4,500 petroleum platforms in the north-central Gulf of Mexico. Explosives are commonly used to remove platforms and have the potential to kill nearby sea turtles. From June 1988-June 1990, the authors used aerial surveys to study turtle density and the spatial relationship between turtles and platforms offshore of Louisiana. They sighted 316 turtles most of which (92%) were loggerheads. Seventy-eight percent were sighted just east of the Mississippi River offshore of the Chandeleur Islands. East of the river, turtle densities ranged from 0.92 (winter) to 4.83 turtles/100 sq km (spring). West of the river, annual densities ranged from 0.11-0.50 turtles/100 sq km. East of the river, three statistical tests indicated that turtles were generally closer to platforms than expected by chance alone. West of the river, turtles were randomly located with respect to platform locations. Before explosives are used, current mitigation measures require that no turtle can be sighted within 1,000 m of the platform. East of the river, the probability of a turtle being within 1,000 m of any platform selected at random was about 60%; west of the river, 2-7%. West of the river to about 92 W, the mitigation measures should protect turtles but offshore of the Chandeleur Islands, special precautions should be taken.

    The European Location Framework (ELF) means a technical infrastructure which will deliver authoritative, interoperable geospatial reference data from all over Europe for analysing and understanding information connected to places and features. The ELF has been developed and set up through the ELF Project, which has been realized by a consortium of partners (public, private and academic organisations) since March 2013. Their number increased from thirty to forty in the year 2016, together with a project extension from 36 to 44 months. The project is co-funded by the European Commission's Competitiveness and Innovation Framework Programme (CIP) and will end in October 2016. In broad terms, the ELF Project will deliver a unique gateway to the authoritative reference geospatial information for Europe (harmonised pan-European maps, geographic and land information) sourced from the National Mapping and Cadastral Authorities (NMCAs) around Europe and including transparent licensing. This will be provided as an online ELF web service that will deliver an up-to-date topographic base map and also as view & download services for access to the ELF datasets. To develop and build up the ELF, NMCAs are accompanied and collaborate with several research & academia institutes, a standardisation body, system integrators, software developers and application providers. The harmonisation is in progress developing and triggering a number of geo-tools like edge-matching, generalisation, transformation and others. ELF will provide also some centralised tools like Geo Locator for searching location based on geographical names, addresses and administrative units, and GeoProduct Finder for discovering the available web-services and licensing them. ELF combines national reference geo-information through the ELF platform. ELF web services will be offered to users and application developers through open source (OSKARI) and proprietary (ArcGIS Online) cloud platforms. Recently, 29 NMCAs plus the

    Forensic science is a fundamental transitional justice issue as it is imperative for providing physical evidence of crimes committed and a framework for interpreting evidence and prosecuting violations to International Humanitarian Law (IHL). The evaluation of evidence presented in IHL trials and the outcomes various rulings by such courts have in regard to the accuracy or validity of methods applied in future investigations is necessary to ensure scientific quality. Accounting for biological and statistical variation in the methods applied across populations and the ways in which such evidence is used in varying judicial systems is important because of the increasing amount of international forensic casework being done globally. Population variation or the perceived effect of such variation on the accuracy and reliability of methods is important as it may alter trial outcomes, and debates about the scientific basis for human variation are now making their way into international courtrooms. Anthropological data on population size (i.e., the minimum number of individuals in a grave), demographic structure (i.e., the age and sex distribution of victims), individual methods applied for identification, and general methods of excavation and trauma analysis have provided key evidence in cases of IHL. More generally, the question of population variation and the applicability of demographic methods for estimating individual and population variables is important for American and International casework in the face of regional population variation, immigrant populations, ethnic diversity, and secular changes. The reliability of various skeletal aging methods has been questioned in trials prosecuted by the International Criminal Tribunal for the Former Yugoslavia (ICTY) in The Prosecutor of the Tribunal against Radislav Krstic (Case No. IT-98-33, Trial Judgment) and again in the currently ongoing trial of The Prosecutor of the Tribunal against Zdravko Tolimir, Radivolje Miletic, Milan Gvero, Vinko Pandurevic, Ljubisa Beara, Vujadin Popovic, Drago Nikolic, Milorad Trbic, Ljubomir Borovcanin (IT-05-88-PT, Second Amended Indictment). Following the trial of General Krstic, a collaborative research project was developed between the Forensic Anthropology Center at The University of Tennessee (UT) and the United Nations, International Criminal Tribunal for the Former Yugoslavia, Office of the Prosecutor (ICTY). The purpose of that collaboration was to investigate methods used for the demographic analysis of forensic evidence and where appropriate to recalibrate methods for individual estimation of age, sex, and stature for specific use in the regions of the former Yugoslavia. The question of "local standards" and challenges to the reliability of current anthropological methods for biological profiling in international trials of IHL, as well as the performance of such methods to meet the evidentiary standards used by international tribunals is investigated. Anthropological methods for estimating demographic parameters are reviewed. An overview of the ICTY-UT collaboration for research aimed at addressing specific legal issues is discussed and sample reliability for Balkan aging research is tested. The methods currently used throughout the Balkans are discussed and estimated demographic parameters obtained through medico-legal death investigations are compared with identified cases. Based on this investigation, recommendations for improving international protocols for evidence collection, presentation, and research are outlined. PMID:18471195

    This paper introduces a unique method for strengthening of platforms and replacing damaged members. Extending the life of existing infrastructure is approved means of decreasing cash expenditures for new platforms and facilities. Platforms can be affected by corrosion, overloading and fatigue. The renovation and repair of existing offshore installations is an important part of offshore engineering. The basis behind this paper is an April, 1993 incident in the Arabian Gulf. A vessel broke loose from its moorings in a severe storm and collided with a wellhead platform. The collision severely damaged the platform buckling seven major support members and cracking joints throughout the structure. In view of the significant damage, there was an urgent need to repair the structure to avoid any further damage from potentially sever winter storm conditions. Various means of repair and their associated costs were evaluated: traditional dry hyperbaric welding, adjacent platforms, grouted clamped connections, and mechanical pipe connectors. The repair was completed using an innovative combination of clamps and wet welding to attach external braces to the structure.

    The bright supernova of AD 1054, which produced the Crab Nebula, was extensively reported in East Asia and there is also a brief Arabic reference. Whether the star was recorded in European history has long been a matter of debate. In this paper we investigate in some detail purported European accounts of the supernova. We conclude that none of these are viable. The new star probably escaped notice in Europe because at the time astronomical knowledge was generally very limited.

    According to history, the population of the British Isles derives its genepool from a succession of invaders and immigrants. The settlement pattern of these invaders gave rise to a patchwork of genepools, shown in previous genetic surveys. Specimens from 1117 blood donors of regionally subdivided East Midlands (Derbyshire, Nottinghamshire and Leicestershire) were analysed for 18 conventional genetic systems (blood groups, serum proteins and red cell enzymes), according to place of residence. Significant differences exist among the five geographically defined sub-populations, and it is argued that these are derived from the historical settlement of continental European populations in the region, especially the Danes and the Vikings.

    This is a systematic review of existing data on dietary selenium (Se) intake and status for various population groups in Europe (including the United Kingdom (UK)) and the Middle East. It includes English language systematic reviews, meta-analyses, randomised controlled trials, cohort studies, cross-sectional and case-control studies obtained through PUBMED searches from January, 2002, to November, 2014, for European data and from 1990 to November 2014, for Middle Eastern data. Reports were selected if they included data on Se intake and status. The search identified 19 European/UK studies and 15 investigations in the Middle East that reported Se intake and Se concentration in water and/or food and 48 European/UK studies and 44 investigations in the Middle East reporting Se status. Suboptimal Se status was reported to be widespread throughout Europe, the UK and the Middle East, and these results agreed with previous reports highlighting the problem. Eastern European countries had lower Se intake than Western European countries. Middle Eastern studies provided varying results, possibly due to varying food habits and imports in different regions and within differing socioeconomic groups. In conclusion, Se intake and status is suboptimal in European and Middle Eastern countries, with less consistency in the Middle East. PMID:25734564

    A new set of European genetic data has been analyzed to dissect independent patterns of geographic variation. The most important cause of European genetic variation has been confirmed to correspond to the migration of Neolithic farmers from the area of origin of agriculture in the Middle East. The next most important component of genetic variation is apparently associated with a north-south gradient possibly due to adaptation to cold climates but also to the differentiation of the Uralic and the Indo-European language-speaking people; however, the relevant correlations are not significantly different from zero after elimination of the spatial autocorrelation. The third component is highly correlated with the infiltration of the Yamna ("Kurgan") people, nomadic pastoralists who domesticated the horse and who have been claimed to have spread Indo-European languages to Europe; this association, which is statistically significant even when taking spatial autocorrelations into account, does not completely exclude the hypothesis of Indo-European as the language of Neolithic farmers. It is possible that both expansions were responsible for the spread of different subfamilies of Indo-European languages, but our genetic data cannot resolve their relative importance.

    In FY13, Pacific Northwest National Laboratory (PNNL) with funding from the Department of Energy’s (DOE’s) Building Technologies Office (BTO) designed, prototyped and tested a transactional network platform to support energy, operational and financial transactions between any networked entities (equipment, organizations, buildings, grid, etc.). Initially, in FY13, the concept demonstrated transactions between packaged rooftop air conditioners and heat pump units (RTUs) and the electric grid using applications or "agents" that reside on the platform, on the equipment, on a local building controller or in the Cloud. The transactional network project is a multi-lab effort with Oakridge National Laboratory (ORNL) and Lawrence Berkeley National Laboratory (LBNL) also contributing to the effort. PNNL coordinated the project and also was responsible for the development of the transactional network (TN) platform and three different applications associated with RTUs. This document describes two applications or "agents" in details, and also summarizes the platform. The TN platform details are described in another companion document.

  9. A new baseline of organic carbon stock in European agricultural soils using a modelling approach.

    Proposed European policy in the agricultural sector will place higher emphasis on soil organic carbon (SOC), both as an indicator of soil quality and as a means to offset CO2 emissions through soil carbon (C) sequestration. Despite detailed national SOC data sets in several European Union (EU) Member States, a consistent C stock estimation at EU scale remains problematic. Data are often not directly comparable, different methods have been used to obtain values (e.g. sampling, laboratory analysis) and access may be restricted. Therefore, any evolution of EU policies on C accounting and sequestration may be constrained by a lack of an accurate SOC estimation and the availability of tools to carry out scenario analysis, especially for agricultural soils. In this context, a comprehensive model platform was established at a pan-European scale (EU + Serbia, Bosnia and Herzegovina, Croatia, Montenegro, Albania, Former Yugoslav Republic of Macedonia and Norway) using the agro-ecosystem SOC model CENTURY. Almost 164 000 combinations of soil-climate-land use were computed, including the main arable crops, orchards and pasture. The model was implemented with the main management practices (e.g. irrigation, mineral and organic fertilization, tillage) derived from official statistics. The model results were tested against inventories from the European Environment and Observation Network (EIONET) and approximately 20 000 soil samples from the 2009 LUCAS survey, a monitoring project aiming at producing the first coherent, comprehensive and harmonized top-soil data set of the EU based on harmonized sampling and analytical methods. The CENTURY model estimation of the current 0-30 cm SOC stock of agricultural soils was 17.63 Gt; the model uncertainty estimation was below 36% in half of the NUTS2 regions considered. The model predicted an overall increase of this pool according to different climate-emission scenarios up to 2100, with C loss in the south and east of the area

    Although there are a number of visualization systems to choose from when analyzing data, only a few of these allow for the integration of other visualization and analysis techniques. There are even fewer visualization toolkits and frameworks from which one can develop ones own visualization applications. Even within the research community, scientists either use what they can from the available tools or start from scratch to define a program in which they are able to develop new or modified visualization techniques and analysis algorithms. Presented here is a new general-purpose platform for constructing numerous visualization and analysis applications. The focus of this system is the design and experimentation of new techniques, and where the sharing of and integration with other tools becomes second nature. Moreover, this platform supports multiple large data sets, and the recording and visualizing of user sessions. Here we introduce the Universal Visualization Platform (UVP) as a modern data visualization and analysis system.

    In addition to the advantages generally associated with orbital platforms, such as improved reliability, economies of scale, simple connectivity of elements, reduced tracking demands and the restraint of orbital object population growth, geostationary platforms yield: (1) continuous access by fixed ground antennas for communications services; (2) continuous monitoring of phenomena over chosen regions of the earth's surface; (3) a preferred location for many solar-terrestrial physics experiments. The geostationary platform also offers a low-risk and economical solution to the impending saturation of the orbital arc/frequency spectrum, maximizing the capacity of individual slots and increasing the utility of the entire arc. It also allows the use of many small, simple and inexpensive earth stations through complexity inversion and high power per beam. Block diagram and operational flowcharts are provided.

  12. The Personal Motion Platform

    The Neutral Body Posture experienced in microgravity creates a biomechanical equilibrium by enabling the internal forces within the body to find their own balance. A patented reclining chair based on this posture provides a minimal stress environment for interfacing with computer systems for extended periods. When the chair is mounted on a 3 or 6 axis motion platform, a generic motion simulator for simulated digital environments is created. The Personal Motion Platform provides motional feedback to the occupant in synchronization with their movements inside the digital world which enhances the simulation experience. Existing HMD based simulation systems can be integrated to the turnkey system. Future developments are discussed.

    This paper describes the Electric Propulsion Orbital Platform (EPOP), of which the primary objective is to provide an instrumented platform for testing electric propulsion devices in space. It is anticipated that the first flight, EPOP-1, will take place on the Shuttle-deployed Wake Shield Facility in 1996, and will be designed around a commercial 1.8 kW arcjet system which will be operated on gaseous hydrogen propellant. Specific subsystems are described, including the arcjet system, the propellant and power systems, and the diagnostics systems.

  14. Siberian Platform: Geology and Natural Bitumen Resources

    Meyer, Richard F.; Freeman, P.A.

    2006-01-01

    Summary: The Siberian platform is located between the Yenisey River on the west and the Lena River on the south and east. The Siberian platform is vast in size and inhospitable in its climate. This report is concerned principally with the setting, formation, and potential volumes of natural bitumen. In this report the volumes of maltha and asphalt referred to in the Russian literature are combined to represent natural bitumen. The generation of hydrocarbons and formation of hydrocarbon accumulations are discussed. The sedimentary basins of the Platform are described in terms of the Klemme basin classification system and the conditions controlling formation of natural bitumen. Estimates of in-place bitumen resources are reviewed and evaluated. If the bitumen volume estimate is confined to parts of identified deposits where field observations have verified rock and bitumen grades values, the bitumen resource amounts to about 62 billion barrels of oil in-place. However, estimates of an order of magnitude larger can be obtained if additional speculative and unverified rock volumes and grade measures are included.

  15. MAPES Plans at EAST

    The Material and Plasma Evaluation System (MAPES) has been successfully built up at the H section of EAST tokamak, consisting of a mid-plane material probe with both active cooling and heating, and multiple diagnostics of sample and boundary plasma. Samples or PFC mock-ups with a weight less than 20 kg and a diameter less than 500 mm can be inserted into the main scrape-off layer plasma from the low field side of EAST. Local background plasma could be characterized by Langmuir probes and thermocouples embedded in the samples, visible and infrared cameras are set at M and D sections. During the 2012 EAST campaign, MAPES has been used to address a variety of PMI issues relevant to ITER. In 2014, several new optical systems will be constructed. A WI emission spectroscopy system and an IR imaging system are being developed and dedicated to the monitoring of the W influx profile and temperature distribution. A set of lens will also be set at H upper port to collect the visible emission light from the lower divertor. The laser induced breakdown spectroscopy (LIBS) is planned to be installed to detect the first wall surface composition at the high field side. In the next EAST campaign, more experiment proposals have been accepted and are being prepared. EAST-MAPES is oriented towards a bridge for international collaborations and is playing an active role in supporting PWI-related researches under tokamak plasma environment.

  16. Experienced discrimination amongst European old citizens.

    This study analyses the experienced age discrimination of old European citizens and the factors related to this discrimination. Differences in experienced discrimination between old citizens of different European countries are explored. Data from the 2008 ESS survey are used. Old age is defined as being 62 years or older. The survey data come from 28 European countries and 14,364 old-age citizens. Their average age is 72 years. Factor analysis is used to construct the core variable 'experienced discrimination'. The influence of the independent variables on experienced discrimination is analysed using linear regression analysis. About one-quarter of old European citizens sometimes or frequently experience discrimination because of their age. Gender, education, income and belonging to a minority are related to experienced age discrimination. Satisfaction with life and subjective health are strongly associated with experienced age discrimination, as is trust in other people and the seriousness of age discrimination in the country. Large, significant differences in experienced discrimination due to old age exist between European countries. A north-west versus south-east European gradient is found in experienced discrimination due to old age. The socio-cultural context is important in explaining experienced age discrimination in old European citizens. Old-age discrimination is experienced less frequently in countries with social security arrangements. Further research is needed to understand the variation in (old) age discrimination between European countries. Measures recommended include increasing public awareness about the value of ageing for communities and changing public attitudes towards the old in a positive way. PMID:22207825

    Snowy to the north and west and cloudy to the east, this MODIS image from February 28, 2002, shows the eastern U.S. Piedmont, a region of relatively low-lying, rolling plateau that runs between New Jersey to the north and Alabama to the south. Bounded on the west by the Appalachians and on the east by the Atlantic Coastal Plain, the Piedmont is fertile agricultural land, and appears to be greening up in (from bottom left) Georgia, South Carolina, and parts of North Carolina, while winter has left its snowy mark on West Virginia (left of center), and to the northeast in Pennsylvania, New York, and New England.

  2. Eclipse Parallel Tools Platform

    Designing and developing parallel programs is an inherently complex task. Developers must choose from the many parallel architectures and programming paradigms that are available, and face a plethora of tools that are required to execute, debug, and analyze parallel programs i these environments. Few, if any, of these tools provide any degree of integration, or indeed any commonality in their user interfaces at all. This further complicates the parallel developer's task, hampering software engineering practices, and ultimately reducing productivity. One consequence of this complexity is that best practice in parallel application development has not advanced to the same degree as more traditional programming methodologies. The result is that there is currently no open-source, industry-strength platform that provides a highly integrated environment specifically designed for parallel application development. Eclipse is a universal tool-hosting platform that is designed to providing a robust, full-featured, commercial-quality, industry platform for the development of highly integrated tools. It provides a wide range of core services for tool integration that allow tool producers to concentrate on their tool technology rather than on platform specific issues. The Eclipse Integrated Development Environment is an open-source project that is supported by over 70 organizations, including IBM, Intel and HP. The Eclipse Parallel Tools Platform (PTP) plug-in extends the Eclipse framwork by providing support for a rich set of parallel programming languages and paradigms, and a core infrastructure for the integration of a wide variety of parallel tools. The first version of the PTP is a prototype that only provides minimal functionality for parallel tool integration of a wide variety of parallel tools. The first version of the PTP is a prototype that only provides minimal functionality for parallel tool integration, support for a small number of parallel architectures, and basis
