The age of zircons from metamorphic rocks of the Taratashsky complex located on the Western slope of the South Urals was determined by the methods of U-Pb isotope dating. The age values obtained suggest a two-stage model of the complex evolution at early stages of its existence. The age of 2913±133 mln. years identifies the age of granulite metamorphism, while the age 2127±65 mln. years indicates the period of the most intensive transformations of the rocks within the complex, which were accompanied by occurrence of high-temperature diaphthorites [ru

Full Text Available Purpose. The purpose of this paper is to study infant mortality in the southern Urals in the 1930 years and the establishment of its causes. The relevance of the researched problem is connected with difficulties of solving demographic problems in the country and the policy of the state to protect motherhood and childhood. Methodology. Basis of research is historical and comparative and historical and systematic methods and critical analysis. Results. Infant mortality is the most significant symptom of demographic decline among the population. This period has been one of the most difficult in the history of our nation, as it was accompanied by major economic, social and political processes that influenced the decline of natural increase among the population. Based on the analysis of Central and local archives, statistical information of mortality of the 1930 years in the region, the authors made the weather dynamics of the number of deaths among children under 1 year and came to the conclusion that the causes of high mortality in the early 1930 years were not only the political processes in society, and especially the famine of 1932–1933 years. The authors have proved that the population of the southern Urals in the 1930 years the mortality rate of children under 1 year was high, not only in relation to the population of the region but for the country as a whole. The number of child deaths in the region was the leader Chelyabinsk region, especially among the urban population. This was due to the high level of population, the predominance of urban population over the rural, the needs of industrialization, that is heavy physical labour of women, weak health care system. By the middle of the period under review, despite the measures taken by the state for the support of motherhood and childhood, the infant mortality rate in the southern Urals remains at a high level, increasing the number of illegal abortions, infectious diseases in the summer

Full Text Available Research objectives: The article reads on the settlement on and the economic use of the south Trans-Urals territories by Turkic communities. Research materials: Published and unpublished sources: books of official orders in the Russian state, chronicles, acts, diplomatic documents, archaeological data, etc. Results and novelty of the research: Traditionally, administrative divisions of Ural and Trans-Urals are considered to be a sort of a naturally emerged structure. Having analyzed the sources, we may conclude: the system of counties’ (uyezd division, as introduced by the Russian state, did not consider the allocation of the communities and their economic management mode. Cattle breeding practices of the local Turks determined the specifity of their economic activities. Many Turks’ volosts (ancestral territories were compound and consisted of two parts: the winter part and the summer one. These two parts could be quite long-distance, divided by the Urals and upon being included into the Russian state they were designated to different uyezds. For instance, one part of Tersyak volost was assigned to Verkhoturskiy uyezd and the second – to Tyumensky uyezd; the western part of the Myakotinskaya (Bakatin volost was located in Ufimsky uyezd and the eastern – in Tyumensky uyezd, which was in the lower reach of the Iset and Pyshma rivers. Consequently, by the moment of being merged into the Russian state, the territories indicated below were economically managed by the local Turks: South Trans-Urals and a part of Cis-Urals, including the territories in the upperstreams of the Ufa and Chusovaya rivers, along the Pyshma and Iset rivers, partially the Tura river, and Tobol between the outflows of the Miass and Tura. The given practice arose in the late Middle Ages and was intimately connected with Shibanids’ claims who ruled in Tyumen and Siberian Khanates. They claimed not only to the territories in the south of West Siberia, Aral Sea region

This work describes the geological position, mineral and chemical composition of high-Mg effusive ankaramites occurring as dykes and lava flows. They were found in the mélange zone of the western margin of the Magnitogorsk island arc zone in the Southern Urals. Data on the liquidus association of phenocrysts and on the composition of the matrix of effusives are given. According to the data obtained, the conclusion was drawn that the ankaramites studied can be attributed to the primary island arc melts, which were not subject to essential differentiation. This type of effusives has not been distinguished previously among island arc volcanogenic formations of the Urals. It is shown that ankaramites can be considered to be primary melts parental for dunite-clinopyroxenites-gabbro complexes of Ural-Alaskan type. The occurrence of ankaramites in the Paleozoic island arc formations of the Urals indicates the wehrlite composition of the mantle as the reason for the extremely wide development of wehrlites and clinopyroxenites in different mafic-ultramafic complexes of the Urals.

2017-05-01

This paper focuses on the Ural Delta in the northern zone of the Caspian Sea, an area with particular characteristics, where intense influence from anthropogenic and natural factors exists, which acts on the fragile delta system. We built a database to integrate the data from the published sources, bathymetric survey, and recent images in the geographical information system (GIS) environment. The results were linked to the Caspian Sea level (CSL) curve, which had many variations, changing the Ural Delta system's dynamics and in its architecture. In addition, the anthropogenic changes contribute to shaping the actual Ural Delta architecture. Through the link between the results and CSL, we reconstructed an evolution model for the Ural Delta system for the last century and identified three different architectures for the Ural Delta, determined by the energy that acted on the system in the last century and by the anthropogenic changes. This work identifies six different delta phases, which are shaped by CSL changes during the last 70 years and by anthropogenic changes. The delta phases recognized are: i) a Lobate Delta phase, shaped during high CSL before 1935; ii) Natural Elongate Delta 1935-1950 formed during rapid CSL fall; iii) Anthropogenic Elongate Delta 1950-1966, formed during rapid CSL fall and after the Ural-Caspian Sea canal construction, which modified the sedimentary deposition on the delta; iv) Anthropogenic Elongate Delta 1966-1982 shaped during low CSL phase; v) Anthropogenic Elongate Delta 1982-1996 formed during a rapid CSL rise phase; and vi) Anthropogenic Elongate Delta 1996-2009 shaped during high CSL that represent the last phase and actual Ural Delta architecture.

A large number of iron and steel companies in the Southern Ural cause severe air pollution in the towns of Karabash (Chelyabinsk region), Sibay (Republic of Bashkortostan), Gai (Orenburg region). The article aims to assess the inhalation effects of hazardous substances on the Southern Ural population. The analysis focused on cancer and non-cancer risks to public health that arise from the surface air pollution caused by the metallurgical industry emissions. The assessment was carried out on the basis of methodological guidelines R 2.1.10.1920-04 using modern sanitary and hygienic standards. We analysed the level of ambient air pollution in the impact area of the metallurgical industry of Karabash, Sibay and Gai over the past eleven years. We established that the ambient air of all the studied towns contain carcinogenic substances that cause unacceptable cancer risks. Formaldehyde has the main share in this risk. We calculated the hazard quotients HQ for the identified priority pollutants and the total hazard indices HI. It is shown that the non-cancer inhalation risk to the Southern Ural population exceeds the safe level manyfold. Sulfur dioxide has the main share in this risk. The conducted assessment showed that in 2006-2016, there was a continuous inhalation exposure of the population to hazardous substances. Sanitary and technological solutions that will allow a reduction of risk to acceptable values are required.

The deformation history of the Late Palaeozoic Ural-Tian Shan junction is discussed for the example of the Karatau ridge in southern Kazakhstan. Three deformation events are recognized. The Late Carboniferous D1 event is characterized by Laramide-style thrust-and-fold structures on the southern margin of Kazakhstan with shortening in a NE-SW direction. The Latest Permian and Triassic D2 event is controlled by compression in an east-west direction, which reflects collisional deformation in the Urals. The main structures are submeridional folds and north-west-striking sinistral strike-slip faults. The Triassic D3 event with shortening in a north-south direction reflects collision of the Turan microcontinent against the southern margin of Kazakhstan. The main structures are north-west-striking dextral strike-slip faults. Our new data provides important clues for the reconstruction of pre-Cretaceous structures between the Urals and the Tian Shan. ?? 2008 Acad??mie des sciences.

Based on items of personal knowledge and on a critical examination of the open report literature, the author establishes the probable occurrence of a major radiation accident in late 1957 or early 1958 in the Chelyabinsk region of the Urals. The reports published deal with contamination of lakes, fish, soil, mammals, birds, insects and trees by cesium 137 and strontium 90. The levels of contamination and the numbers of animals sampled lead him to assume that the source of the accident was radioactive wastes from plutonium producing reactors which had been inadequately disposed of, and that the contaminated area was of the order of 100 sq.km. Relevant CIA documents released are reproduced. (JIW)

Full Text Available Distribution of the rodent communities in the Sub-polar Urals is analysed. This part of the range, between 64° and 66°N, includes the highest peaks, is very scarcely settled and has been rarely studied. However, the area is interesting for biogeography, being a border zone separating European and Siberian lowland faunas. Comparison of results with those from expeditions undertaken in 1927 and in 1972, allows to evaluate changing trends in the local rodent communities, and to relate these trends to changes in the environmental conditions. The results help to emphasize the barrier role played by Sub-polar Urals for the species of rodents inhabiting both sides of the range, and also show the shifting of southern rodent forms northwards, or the moving upwards of other lowland species. This could be seen as an additional evidence of current climate warming trends.

On analyse la répartition des communautés de rongeurs dans les Durais Subpolaires, une section de la chaîne comprise entre les 64° et les 66° de latitude N. Cette partie est très peu peuplée, elle possède les pics les plus hauts de la chaîne et a été rarement étudiée. Il s'agit d'une région intéressante, car c'est la frontière entre les plaines européennes et les plaines orientales de la Sibérie. En comparant les observations effectuées en 1927 et en 1972 avec celles des dernières années, on peut voir les tendances de changement des groupements de rongeurs de la région, et les interpréter en fonction des changements dans l'environnement. Les résultats permettent de mieux comprendre le rôle de barrière qui jouent les Durais Subpolaires pour les espèces de rongeurs situées d'un coté et d'autre de la chaîne. Aussi, ils permettent de verifier le déplacement vers le nord deformes méridionales et l'élévation en altitude d'autres, ce qui pourrait être vu comme une preuve additionnelle de la tendance au réchauffement global.

Main consistent patterns of Stromatoporoid Development in the Late Ordovician and Silurian in the North Urals Palaeobasin

Science.gov (United States)

Antropova, E.

2009-04-01

In the history of the Earth there have been no basins with similar characteristics. The North Urals palaeobasin had its own unique features. The dominant benthic organisms of basin ecosystem during the Ordovician and Silurian were stromatoporoids, corals, and brachiopods. This fauna is vitally important for the aims of stratigraphy so long as conodonts are extremely rare in sections of the Northern Urals area. The most complete ordering of stromatoporoid complexes has been established and made it possible to estimate rates and measures of extinction at a level of the province. It was also found out that stromatoporoids were organisms responsive to subtle changes of environment and that they accommodated differently to those changing conditions. The evolution of stromatoporoids was accompanied by phylogenetic reorganization and formation of endemic communities in the Late Ordovician and Early Silurian. In the Late Silurian taxonomical diversity of stromatoporoids was mainly controlled by migration processes and cosmopolites with wide palaeogeographic links prevailed in the palaeobasin. Therefore palaeobasin at that time was open to stromatoporoid fauna migration which is confirmed by the occurrence of genera and species that disperse in coeval deposits of many areas, for example, Baltic States, Sweden, Ukraine (Podolia), Western Siberia, Arctic islands of Russia, Mongolia, Canada (islands). The evolution of stromatoporoid communities in the Ordovician-Silurian was intermitted by biotic crises. The analysis of stromatoporoid development helps to define crucial points of ecosystem's reorganizations coinciding with critical geological and biotic events in the history of the North Urals palaeobasin existence, as well as global events during the Ordovician and Silurian (Hirnantian Event, Ireviken Event, Lau Event). The analysis of crises indicates local dependence of stromatoporoid biodiversity on depositional environments. Large local biocenos reorganizations and biotic

The paper describes the first finding of quintinite [Mg4Al2(OH)12][(CO3)(H2O)3] at the Mariinsky deposit in the Central Urals, Russia. The mineral occurs as white tabular crystals in cavities within altered gabbro in association with prehnite, calcite, and a chlorite-group mineral. Quintinite is the probable result of late hydrothermal alteration of primary mafic and ultramafic rocks hosting emerald-bearing glimmerite. According to electron microprobe data, the Mg: Al ratio is 2: 1. IR spectroscopy has revealed hydroxyl and carbonate groups and H2O molecules in the mineral. According to single crystal XRD data, quintinite is monoclinic, space group C2/ m, a =5.233(1), b = 9.051(2), c = 7.711(2) Å, β = 103.09(3)°, V = 355.7(2) Å3. Based on structure refinement, the polytype of quintinite should be denoted as 1M. This is the third approved occurrence of quintinite-1M in the world after the Kovdor complex and Bazhenovsky chrysotile-asbestos deposit.

Full Text Available The paper deals with one of the most urgent problems of language teaching in Russia – the need for raising the quality of foreign language and culture teaching in compulsory secondary school. By analyzing the current normative documents and perspectives of further development, the basic values of language teaching were highlighted, correlated with the teaching experience and achievements of the pre- revolutionary era. For the first time, the issue was discussed at the regional level of one of the remote Russian territories–to the south of the Urals. The basic research methods include the historical, logical and comparative analysis of language teaching in the pre-revolutionary era reflected in some previously unknown archives documents. The updating of the historic pedagogical experience emphasized in the paper could, on the one hand, preserve the national language teaching traditions, and on the other hand, give way to innovative regional projects facilitating the language teaching, multilingualism and multicultural trends in society.

Full Text Available In the article, relevant problems of social and professional health of teachers of the Ural higher education institutions are analyzed. The author recognizes that the higher education is created as an interaction between participants of educational process, each of which at the same time acts both as the subject pursuing the valid aims, and as object of orientation for other individuals of the environment of the immediate environment. On the basis of statistical data, the author shows that in socio-economic behavior of the vast majority of students of the Ural higher education institutions are inherent as common features of deviant subculture of youth (addiction to alcohol and drugs, violence manifestations, prostitution etc., and special, connected with educational process (admissions of occupations, use of cribs, plagiarism when performing term papers, diplomas, roughness and tactlessness in relation to teachers, etc.. According to the author, the dominating deviant feautre of modern students — insufficiently developed diligence and unavailability to overcoming difficulties. Development of professional and personal qualities and competences of the expert assumes updating of motivation of students, their active adaptation to educational process, increase of their responsibility for assimilation of the training program and the social behavior accompanying it. The author assume that developen negative social well-being of professional group of teachers of the higher school is determined by low prestige of this profession in society, sharp differentiation of compensation on regions, an ambiguity of the purposes of reforming of the higher school, complication and ambiguity of their professional roles. Conclusions and offers of the article are based on results of a number of the complex sociological researche, which have been carried out in 2010-2013 in higher education institutions and comprehensive schools of Ural under the scientific management

Full Text Available In Slovenia the Ural Owl (Strix uralensis is on its south-western limit of distribution and belongs to the southern subspecies Strix uralensis macroura. Dark coloured owls are characteristic for this subspecies and represent between 5 to 15% of the population. Slovenian breeding population size is estimated at 400 to 700 pairs. The densities of territories ranges between 0.9 to 13.4 territories per 10 km2, and the highest are reached in mountain forests of southern Dinaric region. In the forests with dominant deciduous trees, e.g. Beech (Fagus sylvatica and Pedinculate Oak (Quercus robur, the breeding densities are significantly higher than in the forests with higher proportion of coniferous trees, e.g. Norway Spruce (Picea abies. The species does not select specific altitude and throughout Slovenia it occurs between 150 and 1600 m a.s.l.  The most of the nest found at natural nest-sites were in tree holes or semi-holes (56% and at the tree stumps (20%. Nest boxes were occupied less frequently in Slovenia with occupancy rate of 29%. At least in mountain regions breeding begins quite late, between 15 March to 21 June. Average clutch size is 3.3 ± 1.0 eggs per nest. About 80% of all nests are successful raising at least one young. The diet shifts significantly between breeding and non-breeding period due to the seasonality in prey availability. According to the biomass the most important prey in breeding period are mice (Muridae, voles (Arvicollidae and mole (Talpa europaea, but in the non-breeding period voles and dormice (Gliridae predominate. Large Fat Dormouse (Glis glis seems to have very important role in the post-breeding period, but not in the breeding period due to its dormancy. As a large forest-dwelling predator the Ural Owl shapes the raptor community in the forest by excluding mezopredator species, as Tawny Owl (Strix aluco, what allows smaller raptors, e.g. Boreal Owl (Aegolius funereus to expend their ranges to lower elevations

The age and emplacement of obducted oceanic crust in the Urals from Sm-Nd and Rb-Sr systematics

International Nuclear Information System (INIS)

Edwards, R.L.; Wasserburg, G.J.

1985-01-01

The Urals contain a 2000 km belt of mafic-ultramafic bodies. The Sm-Nd and Rb-Sr systematics of two of these bodies, the Kempersai Massif in the South Ural Mountains and the Voykar-Syninsky Ophiolite Complex in the Polar Ural Mountains have been examined. These data confirm the hypothesis that these bodies represent fragments of pre-collision oceanic crust and establish constraints on the nature and timing of events in the Uralian Orogeny. Two Kempersai gabbros define Sm-Nd internal isochrons of 397 +- 20 My and 396 +- 33 My with epsilonsub(Nd)(T) = +8.7 -+ 0.6 and +8.4 -+ 1.3, respectively. Whole rock samples of pillow basalt, diabase, gabbros, troctolite, and a metasediment give Sm-Nd values which lie on this isochron indicating that these rocks are genetically related and have an igneous crystallization age of 397 My. Whole rock samples of Voykar-Syninsky diabase, gabbros, and clinopyroxenite give Sm-Nd values which lie on or within proportional 1 epsilon-unit of this isochron indicating an age and epsilonsub(Nd)(T) virtually identical to those of Kempersai. epsilonsub(Nd)(T) for the Kempersai and Voykar-Syninsky mafic samples range from +7.3 to +9.0 with an average value of +8.4. This indicates that the Urals ophiolites are derived from an ancient depleted mantle source and are most plausibly pieces of the oceanic crust and lithosphere. The fact that a metasediment has the same epsilonsub(Nd)(397 My) as the other samples indicates derivation from an oceanic source with negligible continental input. epsilonsub(Nd)(T) for the massifs is proportional 1.5 epsilon-units lower than the average for modern MORBs.

Gonzalez, M.A.; Ott, R.L.

1993-01-01

The serious environmental problems of the South Urals Region of Russia have been broadly described in a report coauthored by Russian weapons scientists. The importance of taking the first steps to prevent further environmental damage and adverse public health effects has been recognized by the international scientific community. Scientists at the Lawrence Livermore National Laboratory have initiated a project to assist the Russians in their pollution prevention efforts. The specific objectives of this project are to: (1) conduct a pragmatic survey of the industrial and governmental pollution sources in a limited geographic region of the South Urals and (2) identify the priorities for pollution prevention and for food and water supply improvements at distribution points. The emphasis is on preventing adverse impacts to human health and improving industrial productivity. This project focuses on immediate pollution problems resulting from current operations and their solutions, not on long-term research related to the large-scale cleanup of legacy wastes. The project emphasizes near-term cost effective solutions to prevent pollution while longer term research aimed at contamination from past practices is pursued by other scientists. The project is being conducted in collaboration with environmental and physical scientists from institutes associated with the Ural Branch of the Russian Academy of Sciences; government officials at the national, regional, and local levels; and non-governmental Russian environmental groups. A broad cross section of Russian technical, political, and environmental abilities and interests is mandatory. This cross section will ensure the technical quality, the political acceptability, and the popular credibility of the project results to the affected Russians in the South Urals. Progress on this project is presented in this paper

The European Union's SOLO (Epidemiological Studies of Exposed Southern Urals Populations) project aims to improve understanding of cancer risks associated with chronic in utero radiation exposure. A comprehensive series of hybrid computational fetal phantoms was previously developed at the University of Florida in order to provide the SOLO project with the capability of computationally simulating and quantifying radiation exposures to individual fetal bones and soft tissue organs. To improve harmonization between the SOLO fetal biokinetic models and the computational phantoms, a subset of those phantoms was systematically modified to create a novel series of phantoms matching anatomical data representing Russian fetal biometry in the Southern Urals. Using previously established modeling techniques, eight computational Urals-based phantoms aged 8, 12, 18, 22, 26, 30, 34, and 38 weeks post-conception were constructed to match appropriate age-dependent femur lengths, biparietal diameters, individual bone masses and whole-body masses. Bone and soft tissue organ mass differences between the common ages of the subset of UF phantom series and the Urals-based phantom series illustrated the need for improved understanding of fetal bone densities as a critical parameter of computational phantom development. In anticipation for SOLO radiation dosimetry studies involving the developing fetus and pregnant female, the completed phantom series was successfully converted to a cuboidal voxel format easily interpreted by radiation transport software.

Agricultural aspects of the radiation situation in the areas contaminated by the southern Urals and Chernobyl accidents

International Nuclear Information System (INIS)

Prister, B.S.

1991-01-01

Being different in nature, the accidents in the Southern Urals and at Chernobyl gave rise to radiation situations with own specific features, affecting, in particular, agricultural activities in the contaminated area. The main specific features of the Chernobyl accident were the vast scale of contamination, the large contamination gradients even at considerable distances from the accident site, the heterogeneity of radioactive fallout distribution at micro-level, the inconsistent nature of changes in soil contamination levels, and separation of the radionuclides from the fallout. In spite of the fundamental differences in the chemical character of the types of radioactive fallout, the radionuclides of 90 Sr and 137 Cs were in both cases readily available for assimilation by plant root systems. In both the Southern Urals and the Ukraine the coefficients of radionuclide build-up in soils with identical agrochemical properties fall within the observation accuracy limits. As a result of the Chernobyl accident, light soils of soddy-podzolic composition were subjected to the greatest contamination, their radionuclide build-up coefficients being 8-15 times higher than those of the chernozem soils in the Southern Urals. An abnormally high level of radiocaesium accumulation was observed in meadow grasses, which explains the leading role of milk contamination in the radiation situation on private holdings. (author)

2018-02-01

Full Text Available Purpose. The purpose of this article is to study the impact of the famine of 1932–1933 years in the population change of the Southern Urals. Methodology. Basis of research is historical and comparative, historical and systematic, methods of critical analysis, which examined a number of historical sources, statistical reports, memoranda, special certificates, which contain information about the events. Results. The famine of 1932–1933 years caused the mark on several generations of people, causing increased mortality among the population of the Southern Urals. The author has proved that the quality of records of births and deaths of that time contained a number of errors. This was due to the availability of land where there was no registrar, and the population is not accustomed to registering births, deaths or marriages in the new soviet form. Therefore, using turnover data on natural and mechanical growth during the 1930 years, it is important to take into account all the shortcomings. The author comes to the conclusion that the highest mortality is observed among children up to one year, then the more the age, the lower the risk of death. Dynamics of mortality by regions of the southern Urals are presented in detail in numerical and percentage terms. Among the population of the southern Urals in the 1930 years, the highest percentage of mortality observed among the villagers, due to the difficulties of rural lifestyle, dominated in this period, the agricultural sector over the industrial one. The study established the specificity of hunger in different areas. In some areas of the southern Urals time frame hunger went beyond generally accepted locally or episodically. The importance of studying the famine of 1932–1933 years caused by a attempt of modern Ukraine to present this tragedy as genocide. The author takes the point of view of a number of local historians about the universality of the tragedy of the famine of 1932–1933 years

Specific features of the horizontal and vertical distribution of uranium and thorium in soils and parent materials of the Southern Urals within the Bashkortostan Republic have been studied with the use of mass spectrometry with inductively coupled plasma. The dependence of distribution patterns of these elements on the local environmental conditions is shown. A scale for soil evaluation according to the concentrations of uranium and thorium (mg/kg) is suggested: the low level, up to 3; medium, up to 9; high, up to 15; and very high, above 15 mg/kg. On the basis of to this scale, the ecological state of the soils is evaluated, and the schematic geochemical map of the region is compiled. The territory of Bashkortostan is subdivided into two parts according to the contents of radioactive elements in soils: the western part with distinct accumulation of uranium and the eastern part with predominant thorium accumulation. This finding supports the charriage (thrust fault) nature of the fault zone of the Southern Urals. The vertical distribution patterns of uranium and thorium in soils of the region are of the same character. The dependence between the contents of these two elements and rare-earth elements has been established. The results of this study are applied for assessing the ecological state of soils in the region.

The East Urals Radioactive Trace (EURT) was formed after a chemical explosion in the radioactive waste-storage facility of the Mayak Production Association in 1957 (Southern Urals, Russia) and resulted in an activity dispersion of 7.4 x 10{sup 16} Bq into the atmosphere. Internal exposure due to ingestion of radionuclides with local foodstuffs was the main factor of public exposure at the EURT. The EURT cohort, combining residents of most contaminated settlements, was formed for epidemiological study at the Urals Research Center for Radiation Medicine, Russia (URCRM). For the purpose of improvement of radionuclide intake estimates for cohort members, the following data sets collected in URCRM were used: (1) Total β-activity and radiochemical measurements of {sup 90}Sr in local foodstuffs over all of the period of interest (1958-2011; n = 2200), which were used for relative {sup 90}Sr intake estimations. (2) {sup 90}Sr measurements in human bones and whole body (n = 338); these data were used for average {sup 90}Sr intake derivations using an age- and gender-dependent Sr-biokinetic model. Non-strontium radionuclide intakes were evaluated on the basis of {sup 90}Sr intake data and the radionuclide composition of contaminated foodstuffs. Validation of radionuclide intakes during the first years after the accident was first carried out using measurements of the feces β-activity of EURT residents (n = 148). The comparison of experimental and reconstructed values of feces β-activity shows good agreement. {sup 90}Sr intakes for residents of settlements evacuated 7-14 days after the accident were also obtained from {sup 90}Sr measurements in human bone and whole body. The results of radionuclide intake reconstruction will be used to estimate the internal doses for the members of the EURT cohort. (orig.)

Full Text Available Welfare is one of the indicators that characterizes the functioning of socio-economic system at any level, which is influenced by many factors. It increases the importance of necessity of choice, estimating risks that affect welfare, and managing their influence. The authors view welfare in the region from two viewpoints: an individual and a territory, which implies definition and estimation of risks for each of them. The goal of the study is to estimate the risks to welfare of an individual and a territory, which means solving the following tasks: 1 defining the category ‘risk to welfare of an individual and a territory’; 2 estimating integral risks for the Ural Federal District’s territories; 3 estimating the probability of integral risk reaching critical zone. The methods of study used by the authors: indicative analysis, integration of objective function through Monte Carlo statistical trials method. The object of the study is the regions of the Ural Federal District (subjects of the Russian Federation, timeframe – 2001–2016, information mass – official data of Russian Federal State Statistics Service. Based on the calculations, the authors conclude the following: all regions of the Ural Federal District are in the high-risk zone and have low probability of reaching critical risk zone. The results can be used in managing the risks through development of roadmaps on minimization of risk and probability of aggravation. The proposed measures allow decreasing the integral risk and increasing welfare level of an individual and a territory

Based on the results of data interpretation and analysis of lithological features, it was assumed that carbonate deposits formed in shallow oxygen-rich environment with high bioproductivity warm water ecosystem, and within the isolated carbonate platform with a steady sinking territory. Some signs indicate that sedimentation during the Kizelovian time occurred in the inner lagoon of a large atoll. The Maldivian archipelago could be a contemporary analogue of the Rezhevskaya carbonate platform.

Cowling, O.; Thomas, E.; Svendsen, J. I.; Haflidason, H.

Paleohydrologic records provide important information concerning the past response of local hydrology to abrupt temperature changes. Arctic hydrology is particularly sensitive to temperature due to feedbacks involving sea ice and ice sheets. The most recent deglacial interval contains multiple abrupt temperature changes, which provide opportunities to study the relationship between temperature, ice sheets, and hydrology. We present a lacustrine δ2Hwax record from Bolshoye Schuchye, in the Polar Ural Mountains, spanning 24.5- 1.3 ka, and interpret hydroclimate conditions at a multi-centennial scale from the Last Glacial Maximum (LGM) through the Holocene. Bolshoye Schuchye's position beyond the reach of local glaciers during the LGM makes it a unique site, since lacustrine paleoclimate records from the Arctic rarely span this entire interval, so Bolshoye Schuchye helps to cover a gap in understanding of paleoclimate. Compound specific analysis of leaf wax hydrogen isotopes (δ2Hwax) is a hydroclimate proxy that can be used to infer moisture source area, transport history, and local aridity. Inferences based on δ2Hwax rely on mechanistic understanding of the process by which hydrogen from meteoric water is incorporated into waxes, and subsequently deposited in lake sediments. The δ2Hwax value of a sample reflects the isotopic composition of precipitation, while also incorporating fractionation that occurs between precipitation and uptake by plants, and biosynthetic fractionation during wax synthesis. Comparisons between different chain length waxes can be used to infer the isotopic composition of terrestrial and aquatic waxes, as terrestrial plants tend to produce longer chain lengths than aquatic macrophytes. The offset between terrestrial and aquatic δ2Hwax, expressed as ɛt-a, indicates differences between the precipitation used by terrestrial plants, and the lake water used by aquatic plants. Significant changes in ɛt-a can represent shifts in local aridity

The implementation of the nuclear programme in the Cheliabinsk region in the Ural, where plutonium for the first Soviet nuclear weapons was produced, involved radioactive contamination of the environment. The end of the cold war in the late 1980s initiated a fruitful co-operation between Russian...... and Western radioecologists. The present study is a joint Russian-Ukrainian-Danish effort to make an independent estimate of the inventories of Sr-90, Cs-137 and Pu-239,Pu-240 from two major contamination events in the South Urals, namely, the Kyshtym accident in 1957 and the Karachay wind dispersion in 1967....... The calculations are based upon deposition measurements of the radionuclides carried out on soil samples assuming that the depositions decreased exponentially with distance from the two sources. The inventory estimates are compared with the available Russian information on the two accidents. (C) 1997 Elsevier...

Features of phenacite mineralization from the Ural emerald mines

Directory of Open Access Journals (Sweden)

M. P. Popov

2017-09-01

Full Text Available The authors consider the problems of development of phenacite mineralization at the Ural Emerald Mines, which is rather well developed and described in the Mariinsky (Malyshevsky and Sretensky (Sverdlovsk emerald-beryllium deposits. Phenacite is widespread in many beryllium deposits, but crystals of jewelry quality, with such large sizes as at the Emerald Mines, form rarely. Despite the prescription of the discovery (1833, and because of the rare occurrence of jewelry quality of crystals, and the presence of more expensive and valuable stones – emeralds and alexandrites – in deposits of the Emerald mines, phenacite remains almost unknown in the precious stones market, and especially abroad. Phenacite mineralization mostly occurs in the micaceous veins represented by gray and greenish-gray phlogopite. Distribution of phenacite in the micaceous veins is extremely uneven. Mineralization is typically nesting. High content of phenacite appears in the micaceous veins, mineral composition of which is mostly phlogopite, veins and concretions of beryllium-containing margarite (B-margarite and chlorite. Content of phenacite is low in the micaceous veins that include phlogopite, plagioclase, beryl, fluorite, smoky quartz. At the Sretensky deposit is located a vein that refers to a new type of ore bodies of the chrysoberyl-phenacite composition lying in ultrabasic rocks. Unlike emerald-bearing micaceous veins that have a northwestern spread, the chrysoberyl-phenacite ore bodies are oriented in the near-latitudinal direction and have a northern incidence at an angle of 75°–80°. The most common form of phenacite crystals on the Emerald Mines is rhombohedral and short columned. Crystals have a large number of faces. The usual shapes are a hexagonal prism and rhombohedrons. Twin crystals are common, druses, columnar aggregates, and spherulites are characteristic. Phenacite can be colorless or slightly colored in wine yellow, sometimes pinkish, light

Late Sarmatian Elite Military Burial From the Southern Urals

2015-12-01

Full Text Available The article is devoted to the burial of a warrior of Late Sarmatian time from the Southern Urals. The complex from mound no. 4 of the burial mound Taksai I is distinguished by large size of barrow and grave. The reconstructed height of the mound was less than 2 meters. The depth of the burial pit was more than 3 meters. For Late Sarmatian culture such dimensions of sepulchral structures are unique. Under the mound the ritual platform from mainland soil was discovered. The found inventory of a warrior-rider included: horse bridle, a set of bladed weapons consisting of a long sword, dagger and knife, as well as a small bronze cauldron. Analysis of inventory allows us to date this burial to the second half of the 3rd century A.D. This burial belongs to an elite funerary complexes of Late Sarmatian culture and is a burial of professional warriors. This social stratum was formed in Late Sarmatian society at the end of the 2nd - first half of the 3rd century A.D. Most of these graves are dating back to the first half of the 3rd century A.D and were found in the Low Don and in the Volga region. The situation in these regions changed in that period due to the invasion of the tribes of the North-Caucasian origin. Their occurrence is associated with the destruction of the Tanais in the Lower Don region and the spread of graves in the T-shaped catacombs in the steppe monuments. The tradition of burying warriors-horsemen of high social status almost disappears in the Volga-Don steppes after the middle of 3rd century A.D. In the Southern Urals where these processes had an indirect influence, the existence of traditional hierarchies of Late Sarmatian society could continue until the end of the 3rd century A.D. Among the parts of a horse bridle the researchers discovered bronze B-shape buckle. These buckles are widely distributed in the 4th-5th centuries A.D. in the basin of the Kama river and the Danube river. The found buckle is the earliest currently known

Full Text Available The mercury content in bottom sediments of Kalkan Lake, of the Uchala district, the Southern Ural. It was assumed that high concentrations of mercury in fish due to pollution of bottom sediments as a result of amalgamation at developing of gold placers. Detailed study of distribution of different elements in sediments show close association Hg with the chalcophylic elements, whose anomalies do not have technogenic nature. Association of mercury with the elements-companions of gold placers is evidence of basic contribution of natural mercury to its anomalous accumulation in sediments and fish. This is result of steady long-term natural mercury pollution.

The Ural owl (Strix uralensis) is the biggest forest-living owl in Austria; however, it became extinct in Austria through poaching and habitat loss more than half a century ago. The birds examined in the present study were breeding pairs from the reintroduction project with the aim of determining exploratory plasma biochemistry reference intervals in Ural owls and evaluating the amount of biological variation between seasons, sexes, and ages. A total of 45 birds were sampled, including 13 adult males, 14 adult females, and 18 juvenile birds. Remarkably, almost all of the analytes showed significant differences between the subgroups, primarily between seasons, followed by age and sex. Only creatinkinase, glucose, lactatdehydrogenase, and triglycerides did not show any significant variations. Despite partitioning of reference values into subgroups according to biological variation diminishing the number of reference individuals in the respective groups, the resulting smaller reference intervals will improve medical assessment. The results of the present study once again demonstrate that significant seasonal fluctuations must be expected and considered in the interpretation. It can be assumed that these differences are probably even greater in free-range birds with considerable changes in food quantity and quality during and between years.

Samples of the mosses Hylocomium splendens, Pleurozium schreberi and surface soil, collected in 1997-2001, were used to study the atmospheric deposition of heavy metals and radionuclides in the South Ural Mountains characterized by intense anthropogenic impact from various industries. A total of 38 elements in soil and 33 elements in moss were determined by epithermal neutron activation analysis. The elements Cu, Cd and Pb were determined in moss samples only by atomic absorption spectrometry. ^{90}Sr and ^{137}Cs activity was measured in surface soil samples also. VARIMAX rotated principal component analysis and GIS maps of factor scores were used to identify and characterise different pollution sources and to point out the most polluted areas.

Transitivizing-detransitivizing typology and language family history

Directory of Open Access Journals (Sweden)

Grünthal Riho

2016-12-01

Full Text Available The transitivizing/detransitivizing typology of Nichols et al. 2004 also proves useful to historical linguistics. We focus on language families of northern Eurasia, chiefly the three oldest families (Indo-European, Uralic, Nakh-Daghestanian, some of their daughter branches aged about 2000-3000 years, and one younger family for which we have data on enough daughters to support a family phylogeny (Tungusic. We use the 18-pair wordlist of Nichols et al. 2004, which typologizes each pair of verbs depending on which of the two is derived. We make some improvements in the coding of grammatical properties and the typologization of pairs. NeighborNet trees based on this information reveal family-wide linguistic geography and areal trends. Adding minimal information about the cognacy or non-cognacy of the roots of the wordlist items produces Neighbor- Net trees which approximate well the known phylogeny of the family. Thus very small closed data sets, collected originally for typology, yield rich information about language family history - strikingly, a mere 18 verbs (9 pairs, coded for morphological type and cognacy, yield a very good genealogical tree - while historical methods have also improved the typology.

Uranium-Bearing Srilankite from High-Pressure Garnetites of the Southern Urals: First Data

Science.gov (United States)

Gottman, I. A.; Pushkarev, E. V.; Khiller, V. V.

2018-04-01

This work presents the results of studying srilankite, a rare zirconium titanate (ZrTi2O6), associated with ilmenite, rutile, zircon, uraninite, and other minerals discovered in high-pressure garnetites of the lherzolite Mindyak massif (Southern Urals). Srilankite occurs as inclusions in ilmenite and rutile of up to several tens of microns in size. It was established for the first time that srilankite contains a significant UO2 admixture (up to 20%). The negative correlation between Zr and U is evidence of isomorphism in the srilankite-brannerite system. The association of srilankite with high-Zr rutile indicates that formation of these minerals occurred at T > 850°C.

Transformation of institute of a family in Ural in the conditions of socio-economic destructions

Full Text Available The article is devoted to the analysis of social risks and deviations related to family group in Ural, manifestations of these risks for a family way of life, socio-economic development of the region. The author emphasizes that today the dialectics of creation and destructions, risks and reliability, optimism and pessimism is illustrated in the various parts of the institute of family in Russia as a whole and, in particular, in the Ural region. In our modern age, there is no risk-free behavior. «Risk — safety» dichotomy means that there is no absolute reliability or safety. Whereas «risk — danger» dichotomy means that it is impossible to avoid risk, making any decisions. The author shows the identity of socio-economic health of the adult population of various regions of the Russian Federation throughout almost the whole quarter of a century on the basis of a number of research assignments conducted by sociologists of Institute of Economics of the UB RAS, in a monitoring mode. Division of the population on rather identical (on particular weight in the total number of the population groups of the Russian society referred to the category of «rich», «medium people» and «poor people» is observed. At the same time, according to the author, the social inequality in principle has both positive, and negative consequences for functioning and society development. The author made an attempt of the problem analysis of «family — children», «fathers — children» from a perspective social risks. The special relevance of these processes in relation to family policy in Russia seeking to pass from depopulation tendencies to a favorable treatment of nation-expanded reproduction is emphasized. Altogether, the level of family wellbeing, first of all, is defined by the quality of the relations in the system of «parents — children». The intra-familial conflicts conduct to family trouble and so for children. In article, the author’s position

Cryogenic Minerals in Caves of the Vizhay River (Northern Urals

2018-03-01

Full Text Available New information on the cryogenic mineral formations at the two Vizhay River caves (Northern Urals is given.   Calcite with the insignificant gypsum admixture predominates in the cryogenic material composition from both caves. In addition, the metastable phases of calcite, such as monohydrocalcite and ikaite were found. In the Saksofon Cave, calcite forms both spherulites and complanate grains. In Lednikovaya Cave, the major part of cryomaterial is presented by spherulites, which may suggests the significant supersaturation of solution. In Lednikovaya Сave, the distinct concentric structure with the growth zones denotes the cryogenic material formation in a thin water film under the partial thawing of upper part of long-term ice mound in summer. In Saksofon Cave the growth zones in crystals are poorly developed that probably caused by the seasonal glaciation in the cave and cryogenic minerals are younger than those in the Lednikovaya Cave.

Assessing radiation exposure of herbaceous plant species at the East-Ural Radioactive Trace

International Nuclear Information System (INIS)

Karimullina, Elina; Antonova, Elena; Pozolotina, Vera

2013-01-01

The East-Ural Radioactive Trace (EURT) is a result of the Mayak Production Association accident that occurred in 1957 in Russia. Radiological assessment improves the interpretation of biological effects of exposure to ionizing radiation. Therefore a modeling approach was used to estimate dose rates on Leonurus quinquelobatus, Silene latifolia, Stellaria graminea and Bromus inermis. Soil-to-organism transfer parameter values are delivered from empirical data of 90 Sr and 137 Cs soil and vegetative plant mass activity concentrations. External and internal whole-body dose rates were calculated using deterministic (The ERICA Tool-Tier 2 and R and D 128/SP1a) and probabilistic (The ERICA Tool-Tier 3) methods. The total dose rate for herbs was under 100 μGy h −1 at the most polluted site. The total absorbed dose rates increased 43–110 times (Tier 3) for different herbaceous plant species along the pollution gradient. Based on these data, it can be concluded that herbaceous plant populations currently exist under low-level chronic exposure at the EURT area. -- Highlights: • A modeling approach (The ERICA Tool-Tier 2, Tier 3 and R and D 128/SP1a) was used to estimate dose rates for herbs growing in the wild at the East-Ural Radioactive Trace. • The highest levels of anthropogenic radiation exposure were determined for herbs at Impact EURT sites. • Total absorbed dose rates increased 43–110 times (Tier 3) for different herbaceous plant species along the pollution gradient. • Total dose rate per plant organism for herbs is under 100 μGy h −1 at the most polluted site. Currently herbaceous plant populations exist under low-level chronic exposure at the EURT area

The crystals of zircon due to their resistance to external impact of various processes can reveal information about the environment of their formation and the inclusions observed of them. Zircon contains different mineral inclusions: biotite, plagioclase, quartz, apatite, etc. However, there is no information about gold inclusions in the zircons from granites of the Sudpolar Urals. The study results of the inclusions of gold in accessory zircon of the Kozhim granitic massif are presented in this paper. The studied mineral is a dark-brown translucent short-prismatic crystal containing the inclusion of gold and the allocations of quartz. According to studies, the inclusion of gold formed during the growth of zircon and it is the gold covered with a thin film of oxide gold. It was confirmed that the crystallization of the studied zircon occurred at a temperature of 800°C and above on the stage of formation of granites of Kozhim massif. The assumption is made about the additional temperature in the course of which was caused by decreasing of temperature up to 700° C and below during postmagmatic stage.

Complex modern micro- and spectroscopic methods for study of siderite concretions in the Lower Carboniferous terrigenous strata on the Kozhym River (Subpolar Urals) have shown that its formation was caused by destruction of clay minerals due to the activity of bacterial communities. The abundance of these bacteria was caused by gas-fluid seeps and bacterial methanogenesis processes in bottom deposits. In basins with normal marine fauna, this led to local desalination, hydrogen sulfide contamination, mass collapse of primary organisms, and the development of element-specific bacteria. The occurrence of these bacteria caused the formation of specific authigenic mineralization in the concretion of sideritic bacteriolites: the framboidal pyrite, sphalerite, galenite, barite, sulfoselenides, and tellurides.

The state of public opinion at the East Urals territory of radioactive contamination of the moment of the adoption of a number of govement acts on rehabilitation may be considered as transitory from the state of actually complete neglect of the problem on the part of the government (1950-70) to that of publicity and taking first practical steps towards development and implementation of rehabilitation policies (1990 s). A primary goal for a program for such territories should be achieving their overall revival on the basis of modern requirements of the population

Boris Sergeevich Pavlov

2012-03-01

Full Text Available In terms of crisis economic development, one of priority goals for the technical institutes of higher education is to train engineers who are competitive on the regional labour markets. The main root of the problem of low prestige of the engineering profession in Russia, the slippage in the personnel training in technical universities lies in the depreciation of engineering work, and reduction of its social and economic attractiveness. The gap between science, education and industry leads to aging of engineering staff at the manufactures and to migration of the most talented engineers into other fields of activity. This paper analyzes current problems of engineers training organization in the Urals. The causes of sharp decline of the engineering profession social status in Russia, the fall of interest of secondary school graduates to continuation of their studies in technical institutes of higher education are reviewed. The authors show that the formation of engineering competence as a defining personal and vocational quality of a specialist involves actualization of the student's motivation, one's active and purposeful adaptation to the educational process, increasing one's responsibility for mastering the curriculum. Conclusions and suggestions of the authors are based on the results of a comprehensive sociological research conducted by them in 2011 in five high schools of the Urals (Yekaterinburg, Nizhnevartovsk and Chelyabinsk. The survey showed that during the stage of young specialists' preparation, cooperation in the «university - enterprise» system is actually shifted to the interaction, in fact, between institute of higher education and young professionals who act as the sellers of their labour. The authors believe that it makes sense to roll over (or rather - to stimulate the active engineering work of the most productive engineering professionals who have reached retirement age. Equally sharp and critical are the issues of

Full Text Available It this paper, the author tries to show that the export orientation of the Ural metallurgy, perceived until recently as its dignity and therefore encouraged by the authorities, actually poses a threat to economic security of the region. Being the basis of the regional economy and of Sverdlovsk region in particular, metallurgical industry has suffered serious loss during the global crisis of 2008-2009, thereby causing considerable damage to the socio-economic development of the region. It is generally accepted, but considered as a temporary loss, which was compensated at the end of the crisis. The author puts some suggestions forward on reduction of the global demand for metals in the coming decade. The author tries to prove that without reorientation of the Ural metallurgy onto the domestic market, such losses are very likely also in the future after the crisis overcoming.

The work of the Soviet ecologists, led by A.I. Il'enko, on birds in the southern Urals area, site of the nuclear disaster in 1958, is discussed. The distribution of 90 Sr and 137 Cs in birds, food chains in a large running-water lake, bird migration patterns, and nest conservatism of ducks have been studied. It is pointed out that the existence of migratory species among contaminated species of the southern Urals provides an opportunity for observers in the West to test the truth about the 1958 nuclear disaster in the southern Urals. It is felt that the reports discussed here corroborate the author's original statement that the Urals nuclear disaster involved nuclear waste rather than a major reactor accident. (U.K.)

To follow up populations exposed to several radiation accidents in the Southern Urals, a cause-of-death registry was established at the Urals Center capturing deaths in the Chelyabinsk, Kurgan and Sverdlovsk region since 1950. When registering deaths over such a long time period, quality measures need to be in place to maintain quality and reduce the impact of individual coders as well as quality changes in death certificates. To ensure the uniformity of coding, a method for semi-automatic coding was developed, which is described here. Briefly, the method is based on a dynamic thesaurus, database-supported coding and parallel coding by two different individuals. A comparison of the proposed method for organizing the coding process with the common procedure of coding showed good agreement, with, at the end of the coding process, 70  - 90% agreement for the three-digit ICD -9 rubrics. The semi-automatic method ensures a sufficiently high quality of coding by at the same time providing an opportunity to reduce the labor intensity inherent in the creation of large-volume cause-of-death registries.

Full Text Available Russian copper company was the first in Russia to start developing porphyry copper deposits. In 2013 the Mikheevsky mining and processing plant with the annual production capacity of 18 mln t of ore was put into exploitation. The use of innovative approaches regarding choice of the technology, high-performance equipment and organization of construction allowed to bring the enterprise to a full capacity and to achieve expected results within three years. On the basis of the experience obtained during design, construction and exploitation of the Mikheevsky mining and processing plant in 2017 the company has started the construction of a new mining and processing plant in the Tominskoye deposit. The first stage anticipates the enterprise production capacity to be equal to 28 mln t with the possibility of its increase up to 56 mln t. The development of porphyry copper deposits in the Urals will allow to provide copper plants with the raw materials over the next 80-100 years.

Sentence processing: linking language to motor chains

Directory of Open Access Journals (Sweden)

Fabian Chersi

2010-05-01

Full Text Available A growing body of evidence in cognitive science and neuroscience is pointing towards the existence of a deep interconnection between cognition, perception and action. According to this embodied perspective language understanding is based on a mental simulation process involving a sensory-motor matching system known as the mirror neuron system. However, the precise dynamics underling the relation between language and action are not yet well understood. In fact, experimental studies are not always coherent as some report that language processing interferes with action execution while others find facilitation. In this work we present a detailed neural network model capable of reproducing experimentally observed influences of the processing of action-related sentences on the execution of motor sequences. The proposed model is based on three main points. The first is that the processing of action-related sentences causes the resonance of motor and mirror neurons encoding the corresponding actions. The second is that there exists a varying degree of crosstalk between neuronal populations depending on whether they encode the same motor act, the same effector or the same action-goal. The third is the fact that neuronal populations’ internal dynamics, which results from the combination of multiple processes taking place at different time scales, can facilitate or interfere with successive activations of the same or of partially overlapping pools.

Animal evolution and atmospheric pO2: is there a link between gradual animal adaptation to terrain elevation due to Ural orogeny and survival of subsequent hypoxic periods?

Science.gov (United States)

Kurbel, Sven

2014-10-22

Considering evolution of terrestrial animals as something happening only on flat continental plains seems wrong. Many mountains have arisen and disappeared over the geologic time scale, so in all periods some areas of high altitude existed, with reduced oxygen pressure (pO2) and increased aridity. During orogeny, animal species of the raising terrain can slowly adapt to reduced oxygen levels.This review proposes that animal evolution was often driven by atmospheric oxygen availability. Transitions of insect ancestors and amphibians out of water are here interpreted as events forced by the lack of oxygen in shallow and warm water during Devonian. Hyperoxia during early Carboniferous allowed giant insects to be predators of lowlands, forcing small amphibians to move to higher terrains, unsuitable to large insects due to reduced pO2. In arid mountainous habitats, ascended animals evolved in early reptiles with more efficient lungs and improved circulation. Animals with alveolar lungs became the mammalian ancestors, while those with respiratory duct lungs developed in archosaurs. In this interpretation, limb precursors of wings and pneumatised bones might have been adaptations for moving on steep slopes.Ural mountains have risen to an estimated height of 3000 m between 318 and 251 Mya. The earliest archosaurs have been found on the European Ural side, estimated 275 Myr old. It is proposed that Ural orogeny slowly elevated several highland habitats within the modern Ural region to heights above 2500 m. Since this process took near 60 Myr, animals in these habitats fully to adapted to hypoxia.The protracted P-Tr hypoxic extinction event killed many aquatic and terrestrial animals. Devastated lowland areas were repopulated by mammaliaformes that came down from mountainous areas. Archosaurs were better adapted to very low pO2, so they were forced to descend to the sea level later when the lack of oxygen became severe. During the Triassic period, when the relative content

Full Text Available The epidemiological characteristics of osteoporotic fractures in Russia have been inadequately studied.Objective: to estimate the incidence rate of osteoporotic fractures in the old age groups of an urban population in the Middle Urals.Subjects and methods. The survey was performed in Pervouralsk, a typical industrial town in the Middle Urals, with a total of 160,860 people, including 54,189 dwellers over 50 years of age (20,746 men and 33,443 women, which amounted to 33.7% of the general population of the town. The survey covered its residents aged 50 years and over who had fractures of the proximal hip (FPH, distal forearm (FDF, distal shin, ribs, or surgical neck of the humerusbetween 1 January 2008 and 31 December 2009. Statistical analysis was made applying the programs Biostatistics, Microsoft Excell 2007, and MedCalc (demo-version. The findings were processed using parametric and nonparametric statistical methods.Results. During two years, 1371 fractures, including FPH, FDF, fractures of the humerus, distal shin, and ribs, were registered in the examined sample of persons aged 50 years and over from Pervouralsk. 383 (27.9% of these fractures occurred in men and 988 (72.1% in women. The incidence rate of all fractures was 1265.0 per 100,000 inhabitants aged 50 years and over (1,477.1 for women and 923.1 for men. FDF were more common in women, the incidence was 787.9 cases per 100,000 population; costal fractures – in men (386.7 per 100,000. The investigation has shown that certain types of fractures are predominant in the oldest age groups. Thus, the incidence rate of FDF and fractures of the distal shin decreases while that of FPH and fractures of the humerus increaseswith age, which is likely to be due to several causes: an age-related decline in bone mass; an increase in the frequency of falls with age; muscle weakness and movement discoordination, which alter the mechanism of fall and increase the risk of femoral and

Estimating Forest Carbon Stock in Alpine and Arctic Ecotones of the Urals

Full Text Available This paper reports on measured carbon stocks in the forests of two tree line ecotones of the Ural region where climate change might improve growing conditions. The first is an alpine ecotone that is represented by an altitudinal gradient of the spruce-dominated forests on the Western slope of the Tylaiskii Kamen Mountain (Western part of the Konzhakovskii-Tylaiskii-Serebryanskii Mountain system, 59°30′N, 59°00′E, at the alpine timber line that has risen from 864 to 960 m above sea level in the course of the last 100 years. The second is an arctic ecotone in larch-dominated forests at the lower course of the Pur river (67°N, 78°E, at the transition zone between closed floodplain forests and open or island-like communities of upland forests on tundra permafrost. According to our results, there are large differences in the carbon of the aboveground biomass of both ecotones across environmental gradients. In the alpine tree line ecotone, a 19-fold drop of the carbon stocks was detected between the lower and higher altitudinal levels. In the arctic ecotone the aboveground biomass carbon stock of forests of similar densities (1300 to 1700 trees per ha was 7 times as much in the river flood bed, and 5 times as much in mature, dense forests as the low density forests at higher elevations. Twelve regression equations describing dependencies of the aboveground tree biomass (stems, branches, foliage, total aboveground part upon stem diameter of the tree are proposed, which can be used to estimating the biological productivity (carbon of spruce and larch forests on Tylaiskii Kamen Mountain and the lower Pur river and on surrounding areas on the base of traditional forest mensuration have been proposed. In order to reduce the labor intensity of a coming determination of forest biomass the average values of density and dry matter content in the biomass fractions are given that were obtained by taking our sample trees.The results can be useful in

Full Text Available Since primitive times, the need to communicate with each other has paved the way for the use different types of languages; and the question of language has become an unsolvable, complex issue. It is not possible to limit language with definitions. Language, as a social institution, differs from other languages with the cultural and social structure it has been shaped through; and forms its own lexicon. Aksan (1996:9 ; considers the lexicon of a language as “a whole made up of not only the words, but also the idioms, communicative expressions, formulaic expressions, proverbs, terms and various sets of expressions of that language.” As there are numerous lexical items in a language, there are numerous cult ural elements as well. Each unit among the lexicon provides an important communication between the speaker of that language and the cultural values to which that language belongs; and strengthens the relationship between them. Formulaic expressions, or in other words, communicative expressions are the most significant ones among these units that constitute the lexicon. Cultural transfer has an important role especially in teaching Turkish to foreigners. The functionality of these units is noteworthy in the transfer and the deliberate use of the cultural elements of that language. The aim of this study is to evaluate the texts in beginner level (A1 Turkish as a foreign language course books in terms of formulaic expressions (communicative expressions. The d ata sources for the study are the A1 level books of Lale and İstanbul series. Transferring the culture is quite important in teaching a language. In order to present the language along with the culture, formulaic expressions (communicative expressions sho uld be included frequently, particularly in the beginner level course books.

Full Text Available This investigation is based on a study of two paleoclimatic curves obtained in the Urals (51–59° N, 58–61° E: i a ground surface temperature history (GSTH reconstruction since 800 A.D. and ii meteorological data for the last 170 years. Temperature anomalies measured in 49 boreholes were used for the GSTH reconstruction. It is shown that a traditional averaging of the histories leads to the lowest estimates of amplitude of past temperature fluctuations. The interval estimates method, accounting separately for the rock's thermal diffusivity variations and the influence of a number of non-climatic causes, was used to obtain the average GSTH. Joint analysis of GSTH and meteorological data bring us to the following conclusions. First, ground surface temperatures in the Medieval maximum during 1100–1200 were 0.4 K higher than the 20th century mean temperature (1900–1960. The Little Ice Age cooling was culminated in 1720 when surface mean temperature was 1.6 K below the 20th century mean temperature. Secondly, contemporary warming began approximately one century prior to the first instrumental measurements in the Urals. The rate of warming was +0.25 K/100 years in the 18th century, +1.15 K/100 years in the 19th and +0.75 K/100 years in the first 80 years of the 20th century. Finally, the mean rate of warming increased in the final decades of 20th century. An analysis of linear regression coefficients in running intervals of 21 and 31 years, shows that there were periods of warming with almost the same rates in the past, including the 19th century.

Regional Resilience of the Ural Federal District in Economic Shocks and Crises: Medico-Demographic and Environmental Aspects

Boris Alengordovich Korobitsyn

2016-09-01

Full Text Available Health, demographic and environmental consequences of 1998 and 2008 economic crises for the Ural Federal District are considered in the paper. Regional resilience is defined as the ability of a regional socio-economic system to withstand, absorb or overcome an internal or external economic shock. The quantitative analysis of regional resilience of the subject entities of the Ural Federal District is based on two interrelated dimensions: resistance, those are the vulnerability or sensitivity of a regional socio-economic system to disturbances and disruptions; and the speed and extend of recovery from such a disruption. Because resilience as a concept captures resistance to the shock and recovery from it, resistance indexes and recovery indexes are used for assessing the impact of regions to recessionary shocks. Three sets of resilience indicators were used: economic, environmental and medico-demographic ones. The main criteria for selecting resilience indicators were their robustness as a measure of the territorial impact of the economic crisis and availability of long time series. Special attention is paid to the question identification of the qualitative and quantitative factors, which form the territorial characteristics enabling some regions to resist, or move out of, economic downturn more effectively than others. Unfortunately, a valid answer to the question why some regions are more able to withstand an economic downturn than others, or are able to recover faster, cannot be given at present. Resilience to an economic shock does not necessarily imply that the economy is otherwise strong and performing well over the longer-term. Regions that experience strong economic growth prior to a shock may appear to be less resilient. Such components of the regional socio-economic system as reserves of natural resources, sectoral structure of regional economy, skills of population, diversified economy and quality of governance do not define uniquely

Full Text Available The main features of the Upper Devonian sediments on the right side of the Ostantsovy Creek (the left tributary of the Malaya Usa River in the eastern part of the Bielsko-Eletskaya structural formational belt on the western slope of the Polar Urals have been considered. The late Frasnian age of these sediments has been determined on the basis of conodonts (the linguiformis zone of the standard conodont scale. The transition from clastic and organic limestones with massive stromatoporoid forms to limestones with fused (reservoir stromatoporoid forms and Palmatolepis biofacies is indicative of the transgressive shift of the linguiformis phase. This transgressive level is an indirect expression of the Upper Kellwasser global event.

Dissociated language functions: a matter of atypical language lateralization or cerebral plasticity?

The left hemisphere is generally considered to harbor language functions. Atypical cortical language lateralization is mainly demonstrated in left-handed and ambidextrous individuals, whereas dissociated language functions have been reported in association with brain injuries as a part of the reorganization process. We present a thoughtful discussion on the underlying mechanisms of dissociated language functions through an illustrative case of dissociated expressive language. A 31-year-old left-handed woman presented with a recurrent left frontal glioma. Preoperative language functional magnetic resonance imaging (fMRI) panel revealed right-sided dominance for two different language tasks (verbal fluency and visual naming), and the word chain task demonstrated maximal activation in the left hemisphere at the posterior margin of the tumor. The patient was operated on awake to assess language functions intraoperatively. Preoperative fMRI findings were confirmed revealing a task-specific dissociation of expressive language functions. Surgical resection was taken to the functional boundaries. Postoperatively, no language dysfunction occurred. Dissociated language functions are prone to occur in long-standing lesions. Different patterns of dissociation may be encountered due to interindividual particularities and cerebral plasticity. The presented patient is unique by demonstrating new insight into expressive language dissociation, emphasizing the role of a preoperative language fMRI panel and the capability of intraoperative language mapping for identifying special language networks.

Pedagogical experiment of the first rector of the Ural state mining institute P.P. Von Weymarn as an effort to reform the higher education institution in 1917-1920

Full Text Available Based on sources recently discovered and included in the database of scientific publications, the article analyzes the pedagogical activity of the scientist-chemist, the first rector and founder of the Ural Mining Institute in Ekaterinburg Petr Petrovich von Weymarn, whose name is now almost forgotten. The article shows that this activity can be evaluated as a pedagogical experiment on reformation of the higher education institution system, which could have been adopted in Russia if Bolsheviks lost the Civil War. Pedagogical activity of von Weymarn has a theoretical basis that he developed under the influence of Wilhelm Ostwald, the Nobel Prize winner in chemistry and the idealist philosopher, as well as the example of the Petrograd (Petersburg Mining Institute, which for von Weymarn was not only an alma mater but an example of a reformist attitudes toward the scientific and pedagogical process in higher education.The article gives a detailed analysis of the currently available philosophical and pedagogical essays of P.P. von Weymarn, known as «Essays on the Energy of Culture», as well as the practical application of these theoretical works on the basis of the Ural Mining Institute in Ekaterinburg and in Vladivostok.With the advent of Soviet power, von Weymarn's pedagogical experiment was forcibly interrupted, and he became «persona non-grata» in the Soviet Union, but now his name is being restored. Unfortunately, he is known either as a chemist or as the founder and first rector of the current Ural State Mining University, but not as a teacher who offered his view of reforming the higher school system. This article fills this gap, revealing not only the work of von Weymarn, but also describing the difficult period of changing the old scientific school system, which could have taken a completely different development path.

Samples of the mosses Hylocomium splendens and Pleurozium schreberi, collected in the summer of 1998, were used to study the atmospheric deposition of heavy metals and other toxic elements in the Chelyabinsk Region situated in the South Urals, one of the most heavily polluted industrial areas of the Russian Federation. Samples of natural soils were collected simultaneously with moss at the same 30 sites in order to investigate surface accumulation of heavy metals and to examine the correlation of elements in moss and soil samples in order to separate contributions from atmospheric deposition and from soil minerals. A total of 38 elements (Na, Mg, Al, K, Ca, Sc, Ti, V, Cr, Mn, Fe, Co, Ni, Zn, As, Se, Rb, Sr, Zr, Mo, Sb, Cs, Ba, La, Ce, Nd, Sm, Eu, Gd, Tb, Dy, Yb, Hf, Ta, W, Au, Th, U) in soil and 33 elements Na, Mg, Al, Cl, K, Ca, Sc, V, Cr, Mn, Fe, Co, Ni, Zn, As, Se, Br, Rb, Ag, Sb, Cs, Ba, La, Ce, Sm, Tb, Yb, Hf, Ta, W, Au, Th, U) were determined by epithermal neutron activation analysis. The elements Cu, Cd and Pb (in moss samples only) were obtained by atomic absorption spectrometry. VARIMAX rotated principal component analysis was used to identify and characterize different pollution sources and to point out the most polluted areas. (author)

Full text: The pilot phase of radon and lung cancer case-control study has been performed in Karpinsk and Pervouralsk towns of Middle Ural region of Russia. The case group consists of 341 persons with lung cancer and living in that towns at least five previous years. The lung cancer diagnoses were carefully verified by instrumental techniques and 70% of its were morphologically validated. The persons for the control group (448) were chosen from the population living in that towns at least five years taking into account the age and sex. The special epidemiological questionnaire was developed which includes the items by the groups of factors as follow: clinical data, social factors, chronic lung diseases, life habit, tobacco smoking, alcohol drinking, diet preference etc. The epidemiological questionnaires were fulfilled for each member of case and control groups. Radon gas concentration and thoron equilibrium equivalent concentration measurements had been performed using nuclear track detectors and grab sampling accordingly in the dwellings of case and control groups members. By preliminary estimation the odds ratios are 1, 0.91, 1.2, 1.1 in the ranges of radon and thoron equilibrium equivalent concentration 0-6, 3-13, 13-36 and 36-370 Bq/m 3 respectively. The deeper and more rigorous analysis as well as different independent approaches will be discussed in the paper.(author)

Moving conceptualizations of language and literacy in SLA

DEFF Research Database (Denmark)

Laursen, Helle Pia

in various technological environments, we see an increase in scholarship that highlights the mixing and chaining of spoken, written and visual modalities and how written and visual often precede or overrule spoken language. There seems to be a mismatch between current day language practices......, in language education and in language practices. As a consequence of this and in the light of the increasing mobility and linguistic diversity in Europe, in this colloquium, we address the need for a (re)conceptualization of the relation between language and literacy.

Gluon chains and multiquark hadrons

International Nuclear Information System (INIS)

Jadach, S.; Jezabek, M.

1979-01-01

A monopole approximation to the confining potential is proposed. In this approximation spatially separated groups of quarks carry a definite total colour charge. The potentials which lead to the formation of gluon chains are discussed. The generalization of a (3,3bar) chain notion, studied by Tiktopoulos, to the case of arbitrary colour charges is given. It is argued that these generalized chains may be unstable with respect to splitting into a system of weakly interacting chains of the (3,3bar) type. A unified picture of the high energy hadronic collisions, based on the gluon chain notion and the monopole approximation is proposed. In the meson-meson sector this picture is equivalent to the topological approach. For the other processes it is similar to the approach of Rossi and Veneziano. However, it is argued that the introduction of the junction line into the quark frame is superfluous. The results are expressed in the language of the coloured dual diagrams which provide a generalization of those of Harari and Rosner. (author)

Sentence‐Chain Based Seq2seq Model for Corpus Expansion

2017-08-01

Full Text Available This study focuses on a method for sequential data augmentation in order to alleviate data sparseness problems. Specifically, we present corpus expansion techniques for enhancing the coverage of a language model. Recent recurrent neural network studies show that a seq2seq model can be applied for addressing language generation issues; it has the ability to generate new sentences from given input sentences. We present a method of corpus expansion using a sentence‐chain based seq2seq model. For training the seq2seq model, sentence chains are used as triples. The first two sentences in a triple are used for the encoder of the seq2seq model, while the last sentence becomes a target sequence for the decoder. Using only internal resources, evaluation results show an improvement of approximately 7.6% relative perplexity over a baseline language model of Korean text. Additionally, from a comparison with a previous study, the sentence chain approach reduces the size of the training data by 38.4% while generating 1.4‐times the number of n‐grams with superior performance for English text.

We present a coordination language for the modeling of distributed database applications. The language, baptized Klaim-DB, borrows the concepts of localities and nets of the coordination language Klaim but re-incarnates the tuple spaces of Klaim as databases. It provides high-level abstractions...... and primitives for the access and manipulation of structured data, with integrity and atomicity considerations. We present the formal semantics of Klaim-DB and develop a type system that avoids potential runtime errors such as certain evaluation errors and mismatches of data format in tables, which are monitored...... in the semantics. The use of the language is illustrated in a scenario where the sales from different branches of a chain of department stores are aggregated from their local databases. Raising the abstraction level and encapsulating integrity checks in the language primitives have benefited the modeling task...

Efficiency of natural self-purification of ecosystems vs. countermeasures applied at the East-Ural Radioactive Trace (EURT)

2012-04-01

As a result of the radiation accident in 1957 at the Production Association "Mayak" (Russia, the Urals) a fast area (23000 km^2), later named the East-Ural radioactive trace, was contaminated. Accidental emission presented by the long-living radionuclides was found to be dominated by Sr-90. In 1967 the EURT area was subjected to a secondary contamination resulting from radioactive sediments transport by wind from "Mayak" technological reservoir, Karachay Lake. Currently, the stock of Sr-90, Cs-137 and Pu-239,240 in the EURT's soil cover consist of 640•10^12 Bq. This study is aimed to compare an efficiency of the countermeasures adopted at the EURT and natural processes responsible for self-purification of contaminated ecosystems. With concern to the principle of ranging the contaminated areas two zones were established: impact and buffer ones. The impact zone is situated near the accident epicenter, i.e. within 2-30 km from of the Trace central axis. After accident this zone was removed from agricultural utilization. The buffer zone has permanent anthropogenic pressure. The native, undisturbed during the reclamation operations, flow adjacent of landscape sites were chosen within the impact and buffer zones. They included of a watershed area and bank area of the lakes. The impact zone demonstrated the lowest concentration of the radionuclides around the frequently flooded lake shore. Absence of anthropogenic pressure, the high density of the plant cover and deficit of the soil moisture in summer time are the main reasons for decreasing the intensity of the water runoff from watershed. As a result the self-purification processes are dominated around the shoreline soils. The buffer zone is characterized by an opposite regularity appeared in increasing of the Sr-90 content in the soils of the lake shore. In this case, the intensive agricultural utilization of the flat watersheds leads to increase of erosion and degradation processes and, as consequently, to the

PALEOMAGNETISM OF SILURIAN AND DEVONIAN VOLCANICS FROM THE CHINGIZ ISLAND ARC, KAZAKHSTAN, AND ITS BEARING ON TECTONIC EVOLUTION OF THE URAL-MONGOL BELT

Full Text Available The tectonic and paleogeographic evolution of the Ural-Mongol belt between the cratons of Baltica, Siberia, and Tarim is the key to the formation of the Eurasian supercontinent during Paleozoic time, but the views on this complicated process remain very disparate and sometimes controversial. Three volcanic formations of the Middle Silurian, LowertoMiddle Devonian and Middle Devonian age from the southwestern boundary of the Chingiz Range (NE Kazakhstan yields what are interpreted as primary paleomagnetic directions that help clarify the evolution of the belt. A singlepolarity characteristic component in midSilurian andesites yields a positive intraformational conglomerate test, whereas dualpolarity prefolding components are isolated from the two Devonian collections. These new data were evaluated together with previously published paleomagnetic results from Paleozoic rocks in the Chingiz Range, and allow us to establish with confidence the hemisphere in which the area was located at a given time. We conclude that NE Kazakhstan was steadily moving northward crossing the equator in Silurian time. These new paleomagnetic data from the Chingiz range also agree with and reinforce the hypothesis that the strongly curved volcanic belts of Kazakhstan underwent oroclinal bending between Middle Devonian and Late Carboniferous time. A comparison of the Chingiz paleolatitudes with those of Siberia shows similarities between the northward motion and rotational history of the Chingiz unit and those of Siberia, which imposes important constraints on the evolving paleogeography of the Ural-Mongol belt.

Climate warming is shifting the elevational boundary between forests and tundra upwards, but the related belowground responses are poorly understood. In the pristine South and Polar Urals with shifts of the treeline ecotone documented by historical photographs, we investigated fine root dynamics and production of extramatrical mycorrhizal mycelia (EMM) along four elevational transects reaching from the closed forest to the treeless tundra. In addition, we analysed elevational differences in climate and vegetation structure, and excavated trees to estimate related changes in the partitioning between below- and aboveground biomass. Fine root biomass of trees (<2 mm) increased by 13-79% with elevation, paralleled by a 35-72% increase in ground vegetation fine roots from the closed forest to the tundra. During the first year of decomposition, mass loss of fine root litter from different vegetation types was greater at lower elevations in the forest-tundra ecotone. The ratio between fine roots of trees and stem biomass largely increased with elevation in both regions, but these increases were not accompanied by a distinct production of EMM. Production of EMM, however, increased with the presence of ectomycorrhizal trees at the transition from the tundra to the forest. Our results imply that the recorded upward expansion of forest into former tundra in the Ural Mountains by 4-8 m per decade is decreasing the partitioning of plant biomass to fine roots. They further suggest that climate-driven forest advances will alter EMM production rates with potential feedbacks on soil carbon and nutrient cycling in these ecosystems.

Full Text Available Libraries and librarians play a central role in organising and communicating knowledge. They are an important part of theknowledge production and use chain. The development and sustenance of a knowledge-based economy hinges on theirability to facilitate the accessibility, retrievability and usability of the knowledge and information that permeates theinformation society. Writers and publishers as part and parcel of the knowledge chain are central to the production anddistribution of ideas. Language is fundamental to their ability to communicate and get their literal messages, expressionsand ideas through. Their preferred language of writing and publishing may mean a difference between the growth anddemise of a language of a society and its culture and civilisation. Many indigenous languages around the globe arestruggling to survive because of various reasons including neglect by writers and publishers. Publishers and writers as majorrole players in the knowledge production and reproduction chain may assist in promoting and preserving indigenouslanguages in general and in South Africa in particular. This may ensure that South Africa’s knowledge economy developswithout sidelining or discriminating against any culture or language. There are challenges and opportunities that writersand publishers are likely to face in attempting to revitalise and empower indigenous languages in South Africa, but theyare not insurmountable. Using a theoretical approach, the purpose of this article is to highlight the role that writers andpublishers may play in revitalising and preserving endangered indigenous languages in South Africa. Recommendations aremade on how the role players may deal with the challenges that have culminated in the neglect of the endangeredindigenous languages.

Sub-fossil beetle assemblages associated with the "mammoth fauna" in the Late Pleistocene localities of the Ural Mountains and West Siberia.

The distribution of beetles at the end of the Middle Pleninglacial (=terminal Quaternary) was examined based on sub-fossil material from the Ural Mountains and Western Siberia, Russia. All relevant localities of fossil insects have similar radiocarbon dates, ranging between 33,000 and 22,000 C14 years ago. Being situated across the vast territory from the southern Ural Mountains in the South to the middle Yamal Peninsula in the North, they allow latitudinal changes in beetle assemblages of that time to be traced. These beetles lived simultaneously with mammals of the so-called "mammoth fauna" with mammoth, bison, and wooly rhinoceros, the often co-occurring mega-mammalian bones at some of the sites being evidence of this. The beetle assemblages found between 59° and 57°N appear to be the most interesting. Their bulk is referred to as a "mixed" type, one which includes a characteristic combination of arcto-boreal, boreal, steppe and polyzonal species showing no analogues among recent insect complexes. These peculiar faunas seem to have represented a particular zonal type, which disappeared since the end of the Last Glaciation to arrive here with the extinction of the mammoth biota. In contrast, on the sites lying north of 60°N, the beetle communities were similar to modern sub-arctic and arctic faunas, yet with the participation of some sub-boreal steppe components, such as Poecilus ravus Lutshnik and Carabus sibiricus Fischer-Waldheim. This information, when compared with our knowledge of synchronous insect faunas from other regions of northern Eurasia, suggests that the former distribution of beetles in this region could be accounted for both by palaeo-environmental conditions and the impact of grazing by large ruminant mammals across the so-called "mammoth savannas".

Discussed are the possibilities of using syntaxa from floristic classification for the analysis of secondary restorative successions after forest cutting in South Ural Region. Peculiarities of secondary forest communities classification that may be viewed as subjects of indigenous vegetation syntaxa forming, sub-associations or could be systematized according to 'deductive' classification introduced by K. Kopecky and S. Heiny are considered. An example is presented of an analysis of communities succession system formed after cutting down hemiboreal pine and birch-pine herbaceous forests of Bupleuro-Pinetum association. Within this system the processes of divergence and convergence of succession series take place. Divergence occur as a result of lifting of the influence caused by dominants edificating role and manifestation of differences in soil humidification, also as a consequence of soil enrichment by mineral elements after burning down the felling debris. The reason behind convergence is grading influence of renewed forest stand. Trends in species richness changes during restorative successions may differ depending on ecotope features. In course of a succession, models of tolerance and inhibition become apparent.

Volchenkov, Dima; Dawin, Jean René

A system for using dice to compose music randomly is known as the musical dice game. The discrete time MIDI models of 804 pieces of classical music written by 29 composers have been encoded into the transition matrices and studied by Markov chains. Contrary to human languages, entropy dominates over redundancy, in the musical dice games based on the compositions of classical music. The maximum complexity is achieved on the blocks consisting of just a few notes (8 notes, for the musical dice games generated over Bach's compositions). First passage times to notes can be used to resolve tonality and feature a composer.

Analysis of internal doses to Mole voles inhabiting the East-Ural radioactive trace

Substantial task of development of approaches to radiation protection of non-human biota is investigation of relationships of exposure to dose, and dose to effects. Small mammals inhabiting territory of the East-Ural Radioactive Trace (EURT) are affected to ionizing radiation for many generations after accident at Mayak plutonium production in 1957. According to results of numerous studies a number of effects of exposure are observed. It is remarkable that the revealed effects are both negative and adaptive. In particular, the analysis of the variability of morphological structures of the axial skull and lower jaw in the population of northern mole vole (Ellobius talpinus Pall.), the burrowing rodent inhabiting the EURT, is of great interest. At the same time there is no reliable assessment of the radiation doses to these animals. Earlier we developed the approach to assess internal doses to mouse-like rodents (mice and voles) caused by incorporated {sup 90}Sr, which is the main dose contributing radionuclide at the EURT. Dose assessments are based on the results of beta-radiometry of intact bone. Routine methods for measuring the activity concentration of {sup 90}Sr in skeleton require ashing of samples, however in morphometric studies the destruction of material should be avoided: the skulls of mole voles are stored in the environmental samples depository of IPAE. Coefficients linking results of beta-radiometry of intact bone and activity concentration of {sup 90}Sr in skull of mouse was obtained basing on comparison of results of beta-radiometry of intact bone and bone ash. Obtained coefficients cannot be directly applied for calculating activity concentration of {sup 90}Sr in mole vole skulls because they are significantly larger. Therefore the additional study is required to assess proper coefficient of conversion from beta-radiometry to activity concentration of {sup 90}Sr. Developed dose assessment procedure includes application of the published values of

The results show that the roles of subdistrict middlemen are extremely crucial in moving up the slabs from the village level to urban areas, where trader-brokers are expecting the slabs to be forwarded directly to crumb-rubber factories.  Changes in world price, hence the profits being accumulated by traders and rubber factories, are not transmitted properly to rubber farmers and/or sharetappers. Information asymmetry, the access over price information, and immediate response of rubber growers to the change in world price could explain this non-cointegration in price data between growers and exporters.  In the near future, the policy reforms in supply chain of natural rubber marketing in Indonesia should carefully address these issues in a more comprehensive manner.  Finally, in order to contribute to the positive environmental and social benefits, the major challenge for natural rubber

Pope, interrupted. A qualitative study on memes, hashtags, and speech chains

Full Text Available This article investigates the reaction, on Twitter, to Pope Benedict XVI’s resignation announcement. Specifically, this is a qualitative study in linguistic anthropology of how memes and hashtags circulated on Twitter between the day of the announcement of said resignation and the Pope’s last day in office, and identifies the speech chains created by them. The analysis of the corpus showed that Twitter users' deployment of hashtags serves two purposes: on the one hand, it creates a topic/comment structure that is later reproduced, modified or abandoned by other users. On the other hand, hashtags function as performative acts that create online ad hoc communities. In addition, this article also claims that English and Romance-language users created and circulated image and text-based memes differently, thus establishing two language-based speech chains. In sum, this article contributes to discussions on informational flux on online platforms by demonstrating that said flux does have constraints, and that those constraints are related to language-based communities of practice.

Full Text Available There are several terms used in Romanian for the English term supply chain. We have counted eleven. It has been adopted in several ways and it is perceived (adapted in several ways in Romania. There are several causes which have determined this fact: the English terminology inconsistence regarding supply chain has been translated into other languages, professionals roots determine the usage (logistics professionals use it for logistics, strategic logistics use it in general etc., the lack of Romanian discussions regarding the new professional terminology at general level and supply chain and logistics in particular. We expose the different ways by which supply chain is reflected in Romanian, we discuss the causes which have generated this total confusion and then we suggest a proper term for supply chain in Romanian, considering the real meaning of the term and the strategies adopted by other countries regarding supply chain adoption. In conclusion, we propose a general adoption and adaptation for the term in Romanian.

Innovative Approaches to the Solution of Searching Hydrocarbons in Deep Horizons of the Volga-Ural Oil and Gas Province

Full Text Available The article draws attention to the problem of hydrocarbon exploration in deep horizons, which is especially important for the old oil and gas bearing provinces, in particular, for the Volga-Ural province. The example of Riphean-Vendian deposits shows that the solution of this problem is possible if we use not only data of the structural plans of the studied horizons, but also the presence in the immediate vicinity of the identified structures of the oil feeding channels (faults allocated by the high-depth CDP seismic survey. Based on a comparative analysis of the structure of the White Tiger field (Vietnam and Zhigulev arch, it was concluded that they are very similar and that it is expedient to set up, within the last tectonic element, purposeful studies to explore the prospects of oil and gas potential of the Precambrian basement.

Effects of air and soil pollution by industrial waste on the fructification of Scotch pine in the Urals

The pollution of aerial environment with smoke gases gives rise to heavy weakening of the forest stands and to reduction of their increment. This was demonstrated convincingly enough, especially in the works of numerous German, Czech, Polish, and Soviet foresters and physiologists. There is far less information on the change of the forest species reproductive capacity in the conditions of heavy pollution. The authors do not have enough observations, showing the effects of smoke gases on characteristics of the forest tree fructification. Therefore, in essence, it is not known until now, how great is the degree of these effects. It is obscure, too, what are the characteristics of quality changes of the seeds of trees suffering from smoke gases. In the present paper are given the results of the investigations carried out in the pine forests growing near industrial centers in the Urals. The main task of the investigations was the establishing of smoke gas effects on the seeding intensity and quality.

Demand chain management - The evolution

Directory of Open Access Journals (Sweden)

D Ericsson

2011-06-01

Full Text Available The concepts of Supply Chain Management (SCM and Demand Chain Management (DCM are among the new and debated topics concerning logistics in the literature. The question considered in this paper is: “Are these concepts needed or will they just add to the confusion?” Lasting business concepts have always evolved in close interaction between business and academia. Different approaches start out in business and they are then, more or less si- multaneously, aligned, integrated, systemised and structured in academia. In this way a terminology (or language is provided that helps in further diffusion of the concepts. There is a lack of consensus on the definition of the concept of SCM. This may be one of the major reasons for the difficulty in advancing the science and measuring the results of implementation in business. Relationships in SCM span from rather loose coalitions to highly structured virtual network integrations. DCM is a highly organised chain in which the key is mutual interdependence and partnership. The purpose is to create a distinctive competence for the chain as a whole that helps to identify and satisfy customer needs and wishes. The classical research concerning vertical marketing systems is very helpful in systemising the rather unstructured discussions in current SCM research. The trend lies in increasing competition between channels rather than between companies, which in turn leads to the creation of channels with a high degree of partnership and mutual interdependence between members. These types of channels are known as organised vertical marketing systems in the classic marketing channel research. The behaviour in these types of channels, as well as the formal and informal structures, roles in the network, power and dependence relations, etc. are well covered topics in the literature. The concept of vertical marketing systems lies behind the definition of demand chains and demand chain management proposed in this paper. A

Ising model on tangled chain - 2: Magnetization and susceptibility

International Nuclear Information System (INIS)

Mejdani, R.

1993-05-01

In the preceding paper we have considered an Ising model defined on tangled chain to study the behaviour of the free energy and entropy, particularly in the zero-field and zero-temperature limit. In this paper, following the main line and basing on some results of the previous work, we shall study in the ''language'' of state configurations the behaviour of the magnetization and the susceptibility for different conditions of the model, to understand better the competition between the ferromagnetic bonds along the chain and the antiferromagnetic additional bonds across the chain. Particularly interesting is the behaviour of the susceptibility in the zero-field and zero-temperature limit. Exact solutions for the magnetization and susceptibility, generated by analytical calculations and iterative algorithms, are described. The additional bonds, introduced as a form of perfectly disorder, indicate a particular effect on the spin correlation. We found that the condition J=-J' between the ferromagnetic interaction J along the chain and the antiferromagnetic interaction J' across the chain is somewhat as a ''transition-region'' condition for this behaviour.

Automated generation of partial Markov chain from high level descriptions

Brameret, P.-A.; Rauzy, A.; Roussel, J.-M.

2015-01-01

We propose an algorithm to generate partial Markov chains from high level implicit descriptions, namely AltaRica models. This algorithm relies on two components. First, a variation on Dijkstra's algorithm to compute shortest paths in a graph. Second, the definition of a notion of distance to select which states must be kept and which can be safely discarded. The proposed method solves two problems at once. First, it avoids a manual construction of Markov chains, which is both tedious and error prone. Second, up the price of acceptable approximations, it makes it possible to push back dramatically the exponential blow-up of the size of the resulting chains. We report experimental results that show the efficiency of the proposed approach. - Highlights: • We generate Markov chains from a higher level safety modeling language (AltaRica). • We use a variation on Dijkstra's algorithm to generate partial Markov chains. • Hence we solve two problems: the first problem is the tedious manual construction of Markov chains. • The second problem is the blow-up of the size of the chains, at the cost of decent approximations. • The experimental results highlight the efficiency of the method

Reference models play an important role in the knowledge management of the various complex collaboration domains (such as supply chain networks). However, they often show a lack of semantic precision and, they are sometimes incomplete. In this article, we present an approach to overcome semantic inconsistencies and incompleteness of the Supply Chain Operations Reference (SCOR) model and hence improve its usefulness and expand the application domain. First, we describe a literal web ontology language (OWL) specification of SCOR concepts (and related tools) built with the intention to preserve the original approach in the classification of process reference model entities, and hence enable the effectiveness of usage in original contexts. Next, we demonstrate the system for its exploitation, in specific - tools for SCOR framework browsing and rapid supply chain process configuration. Then, we describe the SCOR-Full ontology, its relations with relevant domain ontology and show how it can be exploited for improvement of SCOR ontological framework competence. Finally, we elaborate the potential impact of the presented approach, to interoperability of systems in supply chain networks.

The mutations in theGJB2(Сх26) gene make the biggest contribution to hereditary hearing loss. The spectrum and prevalence of theGJB2gene mutations are specific to populations of different ethnic origins. For severalGJB2 mutations, their origin from appropriate ancestral founder chromosome was shown, approximate estimations of "age" obtained, and presumable regions of their origin outlined. This work presents the results of the carrier frequencies' analysis of the major (for European countries) mutation c.35delG (GJB2gene) among 2,308 healthy individuals from 18 Eurasian populations of different ethnic origins: Bashkirs, Tatars, Chuvashs, Udmurts, Komi-Permyaks, Mordvins, and Russians (the Volga-Ural region of Russia); Byelorussians, Ukrainians (Eastern Europe); Abkhazians, Avars, Cherkessians, and Ingushes (Caucasus); Kazakhs, Uzbeks, Uighurs (Central Asia); and Yakuts, and Altaians (Siberia). The prevalence of the c.35delG mutation in the studied ethnic groups may act as additional evidence for a prospective role of the founder effect in the origin and distribution of this mutation in various populations worldwide. The haplotype analysis of chromosomes with the c.35delG mutation in patients with nonsyndromic sensorineural hearing loss (N=112) and in population samples (N =358) permitted the reconstruction of an ancestral haplotype with this mutation, established the common origin of the majority of the studied mutant chromosomes, and provided the estimated time of the c.35delG mutation carriers expansion (11,800 years) on the territory of the Volga-Ural region.

PALEOTECTONIC AND PALEOGEOGRAPHIC CONDITIONS FOR THE ACCUMULATION OF THE LOWER RIPHEAN AI FORMATION IN THE BASHKIR UPLIFT (SOUTHERN URALS: THE TERRANECHRONE® DETRITAL ZIRCON STUDY

Directory of Open Access Journals (Sweden)

T. V. Romanyuk

2018-01-01

Full Text Available The TerraneChrone® (LA-ICP-MS technique has been applied to carry out an integrated study of detrital zircons in sandstones sampled from the basal horizons of the stratotypical Riphean sequence in the Southern Urals, specifically the Navysh and Chudin suites of the Ai Formation of the Burzyan Group in the Bashkir Uplift. The concentrations of trace elements in the detrital zircons suggest that the role of oceanic or marginal-marine complexes among the primary sources of zircons was insignificant, and show a better agreement with the intra-continental rather than passive-margin origin of the Riphean basin, whose basal levels are composed by the Ai Formation. The U/Pb ages of zircons from samples K13-206 and M08-16-1 are generally similar: the Paleoproterozoic zircons predominate (the dominant peaks are actually coincident, 2063 and 2055 Ma, and only a few grains of the Archean age are present. Despite the similar U/Pb ages of the detrital zircons, these two samples considerably differ in their Hf isotopic features and the concentrations of trace elements, which means that the zircons in the studied sandstones are of different geodynamic origin. The characteristics of these zircons can be explained by a model showing the Ai Formation in the Navysh graben that is a rift structure and a predecessor of the Kama-Belaya aulacogene in the inner Volga-Ural region of the Paleoproterozoic supercontinent Columbia. At the initial stage of rifting, the granitoid complexes with a lower total silicic acidity, which composed the graben walls, had been eroded; as a result of erosion, coarse clastic rocks accumulated within the Navysh graben and formed the Navysh suite. A specific “carbonatitic” complex containing zircons (about 2.0, 2.5, 2.85 and 3.6 Ga and the Palaeoarchean crustal material in the substrate of their parent rocks was also eroded. In the final stage of rifting, already at the initial stages of the development of the Kama-Belaya aulacogen

THE STRATEGY FOR CREATION OF THE MODERN CONCEPT OF INTEGRATIVE-HOLISTIC EDUCATION (A CASE STUDY OF MINING SCHOOLS OF THE URALS

Full Text Available Introduction. The relevance of the problem under study is caused by the contradiction between the necessity of fundamentalization of education, raising it to the level of the requirements of integral human development and the deepening disintegration of all sides of his life, including vocational education.The aim of the present publication is philosophical and pedagogical reflection and development of mechanisms for mainstreaming integrative-holistic approach when building a hypothetical model of professional education, aimed at provision of strategic turn towards more balanced (dialectical approach to the traditional values of education. In particular, it concerns the experience of mining schools of the Urals.Methodology and research methods. A leading approach to the study of this problem is an integrative-holistic approach (PPI that can identify the holistic nature of the pedagogical system in which: a inter-transformation of cooperated parts occurs not at the expense of each other, but on behalf of each other part; b the existence of common points of contact between the cooperated components is complemented by the coexistence of the opposite, sometimes mutually exclusive sides of life; c the idea of the priority of the whole is in harmony with the idea of polycentrism.Results and scientific novelty. The study shows the failure of the monopoly of the prevailing doctrine of competence-based education as a means for the successful resolution of global problems of reintegration of human existence and therefore postulated the necessity of antinomization (diversification of education. The authors make the original hypothesis of the construction of the concept of vocational education on the basis of the reconstruction of experience of the mining schools of the Urals and prove the prospectivity of integrative-holistic strategy of reconstruction of educational experience in modern conditions.

Full Text Available Purpose. The purpose of this article is to show the complexity and ambiguity of relations between Kazakhs and Russian military (primarily Cossacks during the advance of Russia in the Kazakh steppe and Central Asia, as well as a reflection of this problem in different sources. Methodology. In the course of the work, we have used diverse sources that shed light on this issue. Among them, documents of XVIII–XIX centuries, mainly from the State archive of Orenburg region (GAOO, as well as from the military historical archive (RGVIA. Used the documents collected by the Lieutenant of the General staff, A.D. Ryabinin, the importance of which is associated with the fact that the archive of the Ural Cossack troops lost during the civil war. Not less important are two major works of officers, military historians and theorists M.I. Iva­nin and M.A. Terentyev directly involved in the campaigns through the Kazakh steppe and the annexation of Central Asia. To a lesser extent the materials used other “sources” of the XIX century the Ural Cossack officers I.I. Zheleznov, N.G. Makushin, and also serving at the Orenburg military Governor V. I. Dahl. An important source is and “Uralskiye voiskoviye vedomostie” – the only newspaper published in the Ural Cossack army in the last third of the XIX century. Results. All these sources allow us to draw some important conclusions. They clearly indicate that the South-Eastern outskirts of Russia was long subjected to raids “nomads”, and it has developed most of the border of the Cossack population sustained hostility to the nomadic neighbors. The hostility persisted for a long time, but during the nineteenth century it was gradually decreasing due to the socio-political and economic changes in parallel decreased and the number of conflicts. The Russian military sometimes showed excessive cruelty, and their commanders, carrying out orders from above, was not always true in the Kazakh population. But it was

Trace Element Compositions and Defect Structures of High-Purity Quartz from the Southern Ural Region, Russia

2017-10-01

Full Text Available Quartz samples of different origin from 10 localities in the Southern Ural region, Russia have been investigated to characterize their trace element compositions and defect structures. The analytical combination of cathodoluminescence (CL microscopy and spectroscopy, electron paramagnetic resonance (EPR spectroscopy, and trace-element analysis by inductively coupled plasma mass spectrometry (ICP-MS revealed that almost all investigated quartz samples showed very low concentrations of trace elements (cumulative concentrations of <50 ppm with <30 ppm Al and <10 ppm Ti and low abundances of paramagnetic defects, defining them economically as “high-purity” quartz (HPQ suitable for high-tech applications. EPR and CL data confirmed the low abundances of substitutional Ti and Fe, and showed Al to be the only significant trace element structurally bound in the investigated quartz samples. CL microscopy revealed a heterogeneous distribution of luminescence centres (i.e., luminescence active trace elements such as Al as well as features of deformation and recrystallization. It is suggested that healing of defects due to deformation-related recrystallization and reorganization processes of the quartz lattice during retrograde metamorphism resulted in low concentrations of CL activator and other trace elements or vacancies, and thus are the main driving processes for the formation of HPQ deposits in the investigated area.

Great tit and pied flycatcher populations on the territory of radioactive trail in the eastern Urals

The purpose of this preliminary study was to evaluate the prospects for using populations of the great tit (Parus major) and the pied flycatcher (Ficedula hypoleuca) in ecological monitoring of territories contaminated with radionuclides. Studies were performed in the summer of 1992 in birch forests of the Southern Urals. Artificial nesting sites (log houses) located 1.5 m above the ground were distributed over territories of two test plots: 30 log houses on the contaminated plot and 60 on the control plot (contamination with Sr-90 1.5 and 2 · 10 -3 mCi/m 2 , respectively). The nesting success in the great tit was similar on both plots, whereas that in the pied flycatcher was significantly greater on the control plot (in a open-quotes cleanclose quotes forest). Pied flycatchers build their nests out of highly radioactive materials, whereas great tits use nonradioactive or weakly emitting materials. Hence, pied flycatcher's nestlings receive a significant radiation dose from components of the nest: From the moment of egg laying, this dose amounts to 0.5 rem. The pied flycatcher can be used as an indicator of radioactive contamination. This species is more sensitive than the great tit, which has been successfully used as an indicator for monitoring the industrial air pollution

Many animals produce vocal sequences that appear complex. Most researchers assume that these sequences are well characterized as Markov chains (i.e. that the probability of a particular vocal element can be calculated from the history of only a finite number of preceding elements). However, this assumption has never been explicitly tested. Furthermore, it is unclear how language could evolve in a single step from a Markovian origin, as is frequently assumed, as no intermediate forms have been found between animal communication and human language. Here, we assess whether animal taxa produce vocal sequences that are better described by Markov chains, or by non-Markovian dynamics such as the 'renewal process' (RP), characterized by a strong tendency to repeat elements. We examined vocal sequences of seven taxa: Bengalese finches Lonchura striata domestica, Carolina chickadees Poecile carolinensis, free-tailed bats Tadarida brasiliensis, rock hyraxes Procavia capensis, pilot whales Globicephala macrorhynchus, killer whales Orcinus orca and orangutans Pongo spp. The vocal systems of most of these species are more consistent with a non-Markovian RP than with the Markovian models traditionally assumed. Our data suggest that non-Markovian vocal sequences may be more common than Markov sequences, which must be taken into account when evaluating alternative hypotheses for the evolution of signalling complexity, and perhaps human language origins. © 2014 The Author(s) Published by the Royal Society.

Population residing in the northern part of the Chelyabinsk oblast and the south eastern part of the Sverdlovsk oblast of Russia affected to accidental exposure since 1957. The territory (East Ural Radioactive Trace - EURT) was contaminated after explosion of container with highly radioactive wastes at the Mayak Production Association. Studies of health effects of exposure in the southern, head part of EURT are conducted in the Ural Research and Practical Center of Radiation Medicine (U.R.P.R.M.). In the 1990's U.R.P.C.R.M. formed a cohort of EURT within Chelyabinsk oblast (14,500 cases and 19,400 external controls). The cohort was followed in 1957-1987 and the results of the study are discussed by Crestinina et al. First results of study on exposure late health effects among rural population in the northern part of the EURT are presented in this paper. Firstly, or the period 1958-2000 a statistically significant increase in cancer mortality associated with accidental exposure at EURT area was observed in the critical group of population of the Kamensky district, Sverdlovsk Region (65 cancer deaths among 691 cases, 90% CI 18-144). The finding is in agreement with the results of a radiation epidemiological study in the southern head part of EURT and model radiation risk assessments. E.R.R. normalized to colon dose is 1.3 Gy-1 (90 % CI 0.36-2.9 Gy-1). Secondly, analysis of the age and temporal factors influence on solid cancers radiation risk allows conclusion on decline of radiation risk in time. At present considerable number of additional radiation-induced cancer deaths are unlikely to appear. Radiation risk of solid cancers realizes at most during 30 post-accident years. Radiation risk declines with age at first exposure and not appeared in the age group >60. Derived age and time dependencies generally agree with results of other radiation epidemiological studies. Thirdly, continuation and development of radiation epidemiological study of the population residing

Workflow control model and SQL Server based register center are used in a prototype system for chaining geoprocessing web services which have been performed functionality decomposition and packed by using extended WPS.

Joint US/Russian Studies of Population Exposures Resulting from Nuclear Production Activities in the Southern Urals

International Nuclear Information System (INIS)

Napier, Bruce A.

2014-01-01

Beginning in 1948, the Soviet Union initiated a program for production of nuclear materials for a weapons program. The first facility for production of plutonium was constructed in the central portion of the country east of the southern Ural Mountains, about halfway between the major industrial cities of Ekaterinburg and Chelyabinsk. The facility now known as the Mayak Production Association and its associated town, now known as Ozersk, were built to irradiate uranium in reactors, separate the resulting plutonium in reprocessing plants, and prepare plutonium metal. The rush to production, coupled with inexperience in handling radioactive materials, lead to large radiation exposures, not only to the workers in the facilities, but also to the surrounding public. Fuel processing started with no controls on releases, and fuel dissolution and accidents in reactors resulted in release of about 37 PBq (1015 Bq) of 131I between 1948 and 1967. Designed disposals of low- and intermediate-level liquid radioactive wastes, and accidental releases via cooling water from tank farms of high-level liquid radioactive wastes, into the small Techa River caused significant contamination and exposures to residents of numerous small riverside villages downstream of the site. Discovery of the magnitude of the aquatic contamination in late 1951 caused revisions to the waste handling regimes, but not before over 200 PBq of radionuclides (with large contributions of 90Sr and 137Cs) were released. Liquid wastes were diverted to tiny Lake Karachay (which today holds over 4 EBq); cooling water was stopped in the tank farms. In 1957, one of the tanks in the tank farm overheated and exploded; over 70 PBq, disproportionately 90Sr, was blown over a large area to the northeast of the site; a large area was contaminated and many villages evacuated. This area today is known as the East Urals Radioactive Trace (EURT). Each of these releases was significant; together they have created a group of cohorts

This work is being carried out as a feasibility study to determine if a long-term course of work can be implemented to assess the long-term risks of radiation exposure delivered at low to moderate dose rates to the populations living in the vicinity of the Mayak Industrial Association (MIA). This work was authorized and conducted under the auspices of the US-Russian Joint Coordinating Committee on Radiation Effects Research (JCCRER) and its Executive Committee (EC). The MIA was the first Russian site for the production and separation of plutonium. This plant began operation in 1948, and during its early days there were technological failures that resulted in the release of large amounts of waste into the rather small Techa River. There were also gaseous releases of radioiodines and other radionuclides during the early days of operation. In addition, there was an accidental explosion in a waste storage tank in 1957 that resulted in a significant release. The Techa River Cohort has been studied for several years by scientists from the Urals Research Centre for Radiation Medicine and an increase in both leukemia and solid tumors has been noted

Invisible and microscopic gold in pyrite: Methods and new data for massive sulfide ores of the Urals

2015-07-01

Au speciation in sulfides (including "invisible" Au), which mostly controls the loss of Au during ore dressing, is discussed. Modern methods of analysis of Au speciation, with discussion of limitations by locality and sensitivity, are reviewed. The results of sulfide investigation by the methods of scanning and transmission electron microscopy, mass spectrometric analysis with laser ablation (LA-ICP-MS), the thermochemical method (study of ionic Au speciation), and automated "quantitative mineralogy," are demonstrated for weakly metamorphosed VHMS deposits of the Urals (Galkinsk and Uchaly). Significant content of Au is scattered in sulfides, such as pyrite, chalcopyrite, and sphalerite, with quantitative predomination of pyrite. The portion of such "invisible" gold ranges from flakes) with a monocrystal diffraction pattern of some particles and a ring diffraction pattern of other particles was registered in the ores of these deposits by the methods of transmission electron microscopy. The low degree (or absence) of metamorphic recrystallization results in (1) predomination of thin intergrowths of sulfides, which is the main reason for the bad concentration of ores (especially for the Galkinsk deposit) and (2) the high portion of "invisible" gold in the massive sulfide ores, which explains the low yield of Au in copper and zinc concentrates, since it is lost in tailings with predominating pyrite.

Tourmaline is abundant at the Mariinsky schist-hosted emerald deposit in the Central Urals, Russia, both in emerald-bearing phlogopite veins (type 1) and later, emerald-free pockets, lenses, and veinlets cutting the phlogopite veins (type 2). The Ca content in tourmaline is influenced by the host rocks (ultramafic and mafic rocks), associated minerals, and minerals crystallized before tourmaline (amphibole, fluorite, margarite). The Na concentration in tourmaline depends on the presence or absence of paragonite, and the association with micas also strongly influences the contents of Li, Zn, Ni, and Co in tourmaline. Type 1 tourmalines associated with phlogopite are relatively depleted in these elements, whereas type 2 tourmalines associated with margarite or paragonite are enriched. Some differences in isomorphic substitutions along with the trace element composition (Zn, V, Sr, Co, REE) may have value in exploration of emerald-bearing and emerald-free veins in schist-hosted emerald deposits. The δ11B values in tourmaline of all types fall in a narrow total range from -11.3 to -8.4‰. These values, combined with a mineralization temperature of 420-360 °C, yield an estimated δ11B fluid composition of -7.4 to -6.8‰ suggesting a mixed source of boron, likely dominated from the granitic rocks surrounding the emerald belt. The narrow range of B-isotope compositions in tourmaline from throughout the Mariinsky deposit suggests a well-mixed hydrothermal system.

Full Text Available Introduction. The relevance of the problem under study is caused by the contradiction between the necessity of fundamentalization of education, raising it to the level of the requirements of integral human development and the deepening disintegration of all sides of his life, including vocational education.The aim of the present publication is philosophical and pedagogical reflection and development of mechanisms for mainstreaming integrative-holistic approach when building a hypothetical model of professional education, aimed at provision of strategic turn towards more balanced (dialectical approach to the traditional values of education. In particular, it concerns the experience of mining schools of the Urals.Methods. A leading approach to the study of this problem is an integrativeholistic approach (PPI that can identify the holistic nature of the pedagogical system in which: a inter-transformation of cooperated parts occurs not at the expense of each other, but on behalf of each other part; b the existence of common points of contact between the cooperated components is complemented by the coexistence of the opposite, sometimes mutually exclusive sides of life; c the idea of the priority of the whole is in harmony with the idea of polycentrism.Results and scientific novelty. The study shows the failure of the monopoly of the prevailing doctrine of competence-based education as a means for the successful resolution of global problems of reintegration of human existence and therefore postulated the necessity of antinomization (diversification of education. The authors make the original hypothesis of the construction of the concept of vocational education on the basis of the reconstruction of experience of the mining schools of the Urals and prove the prospectivity of integrative-holistic strategy of reconstruction of educational experience in modern conditions. The system of technological and methodological support of the

DCHAIN: A user-friendly computer program for radioactive decay and reaction chain calculations

International Nuclear Information System (INIS)

East, L.V.

1994-05-01

A computer program for calculating the time-dependent daughter populations in radioactive decay and nuclear reaction chains is described. Chain members can have non-zero initial populations and be produced from the preceding chain member as the result of radioactive decay, a nuclear reaction, or both. As presently implemented, chains can contain up to 15 members. Program input can be supplied interactively or read from ASCII data files. Time units for half-lives, etc. can be specified during data entry. Input values are verified and can be modified if necessary, before used in calculations. Output results can be saved in ASCII files in a format suitable for including in reports or other documents. The calculational method, described in some detail, utilizes a generalized form of the Bateman equations. The program is written in the C language in conformance with current ANSI standards and can be used on multiple hardware platforms

2008-01-01

In this paper we present a verification of the module of the lattice code DRAGON 3.06 used for processing microscopic cross-section libraries, including their associated depletion chain. This verification is performed by reprogramming the capabilities of DRAGON in another language (MATLAB) and testing them on different problems typical of the CANDU reactor. The verification procedure consists in first programming MATLAB m-files to read the different cross section libraries in ASCII format and to compute the reference cross-sections and depletion chains. The same information is also recovered from the output files of DRAGON (using different m-files) and the resulting cross sections and depletion chain are compared with the reference library, the differences being evaluated and tabulated. The results show that the cross-section calculations and the depletion chains are correctly processed in version 3.06 of DRAGON. (author)

The Wada test has been the gold standard for determining hemispheric language dominance (HLD) in the presurgical evaluation of patients scheduled for neurosurgical procedures. As it poses inherent risks associated with intra-arterial catheter techniques and as it occasionally fails to indicate language dominance, an alternative reliable test is needed. We quantitatively assessed the results of functional magnetic resonance imaging (fMRI) using the Shiritori task, a Japanese word chain, to identify the threshold for correctly predicting HLD. The subjects were 28 patients with intractable epilepsy scheduled to undergo the Wada test and focus resection. We set the region of interest (ROI) on the bilateral Brodmann areas 44 and 45 (BA 44 and 45). To compare the functional activity at both ROIs we calculated the language laterality index (LI) using the formula: [VL-VR]/[VL+VR]×100, where VL and VR indicated the number of activated voxels in the left and right ROIs, respectively. As 2 patients were excluded due to the lack of activation in either ROI, the final study population consisted of 26 patients. By the Wada test, HLD was left in 20, right in 3, and equivocal in 3. At a cut-off of LI+50, the predictive sensitivity and specificity for left HLD were 85% (17/20) and 100%; right HLD was predicted in a single patient (sensitivity 33.3%, specificity 100%). The fMRI using the Shiritori task showed good activation in ROI of BA 44 and 45. At a cut-off of LI+50, LI of BA 44 and 45 predicted HLD identified by the Wada test with high specificity.

Tilapia has been named as the 'food fish of the 21st century' and has become the most important farmed fish. China is the world leader in tilapia production and export. Identifying information and functional requirements is critical in developing an efficient traceability system because traceability has become a fundamental prerequisite for exporting aquaculture products. This paper examines the export-oriented tilapia chains and information flow in the chains, and identifies the key actors, information requirements and information-capturing points. Unified Modeling Language (UML) technology is adopted to describe the information and functionality requirement for chain traceability. The barriers of traceability system adoption are also identified. The results show that the traceability data consist of four categories that must be recorded by each link in the chain. The functionality requirement is classified into four categories from the fundamental information record to decisive quality control; the top three barriers to the traceability system adoption are: high costs of implementing the system, lack of experienced and professional staff; and low level of government involvement and support.

The article deals with the vital problem of the implementation of the Program to enhance the competitiveness of the South Ural State University (SUSU) among other scientific and educational centers, which defines the main objective - to form a world-class university. According to the set objective, the most important task is to build a landscaped campus, which can be efficiently solved by the architectural means. The solution of this task is based on the scientific methods of the territorial and architectural improvement of the main university building complex development in the northern academic area and the architectural and aesthetic improvement of the space structural arrangement of the buildings. The author analyzes the global practice of modern campuses in Russia and abroad based on the Internet resources. The author carried out some additional on-site surveys of foreign campuses in Australia, Canada and China. The essence of the architectural concept of the first university campus development stage lies in the science-based achievement of a harmonious architectural and space unity of solid and plane elements of the site development, landscape arrangement of the main building’s courtyard and the adjacent territories with an efficient use of the relief, water areas and planting, allotment of additional spaces for landscaped areas due to a split-level arrangement, including a landscaped platform, increase of the underground space utilization share with the arrangement of an underground car parking and an underground walkway considering the environmental requirements. Further, it is planned to use the author’s methodological approach for the southern academic and the northern residential university areas, which will allow to create a duly completed landscaped SUSU campus with a developed infrastructure according to the international standards.

The East Ural Radioactive Trace is a result of the accident at the Production Association Mayak in 1957(the Kyshtym accident). The {sup 90}Sr was the main contaminant among long-lived radionuclides. Most of it was concentrated in the zone closest to the accident epicentre to the north-west (a narrow sector of about 15 deg., 35 km long). Later, in 1967, the EURT area was contaminated again with air-borne radioactive sediments from Lake Karachay, which had been used by the PA Mayak for storage of liquid radioactive waste. At this case the primary contaminant was {sup 137}Cs most of which was spread within 60 deg. sector oriented in the same direction (Aarkrog et al., 1997; Romanov et al., 1990). Our earlier radioecological studies included the assessment of integrated quantities of {sup 90}Sr, {sup 137}Cs, and {sup 239,240}Pu within the central axis of the trace (Pozolotina et al., 2008; Molchanova et al., 2009). The aim of this investigation was the current assessment of integrated stocks of {sup 90}Sr, {sup 137}Cs, and {sup 239,240}Pu in soils of the head part of the EURT along the central axis and the adjacent areas, to map the contamination data of the studied area using established geostatistical models by ArcGIS 9.3 (ESRI, USA). An inventory of the existing data (38 sampling locations) was performed earlier (Molchanova et al., 2009). Currently the database has information on 102 soil profile cuts. Taking into account the presence of global trends and anisotropy in the source data, ordinary kriging interpolation method was used. Geostatistical data analysis was performed for the determination of the basic parameters of spatial dependencies and the integral assessment of long-lived radionuclides in soils of the central, east peripheral, and west one parts of the trace. This analysis employed simplified geometric models (sector- and rectangle-shaped areas). The Monte Carlo technique was used for quantitatively assesses the uncertainty of the integrated stocks to

CHAINS-PC, Decay Chain Atomic Densities

International Nuclear Information System (INIS)

1994-01-01

1 - Description of program or function: CHAINS computes the atom density of members of a single radioactive decay chain. The linearity of the Bateman equations allows tracing of interconnecting chains by manually accumulating results from separate calculations of single chains. Re-entrant loops can be treated as extensions of a single chain. Losses from the chain are also tallied. 2 - Method of solution: The Bateman equations are solved analytically using double-precision arithmetic. Poles are avoided by small alterations of the loss terms. Multigroup fluxes, cross sections, and self-shielding factors entered as input are used to compute the effective specific reaction rates. The atom densities are computed at any specified times. 3 - Restrictions on the complexity of the problem: Maxima of 100 energy groups, 100 time values, 50 members in a chain

Assessment of communication abilities in multilingual children: Language rights or human rights?

Science.gov (United States)

Cruz-Ferreira, Madalena

2018-02-01

Communication involves a sender, a receiver and a shared code operating through shared rules. Breach of communication results from disruption to any of these basic components of a communicative chain, although assessment of communication abilities typically focuses on senders/receivers, on two assumptions: first, that their command of features and rules of the language in question (the code), such as sounds, words or word order, as described in linguists' theorisations, represents the full scope of linguistic competence; and second, that languages are stable, homogeneous entities, unaffected by their users' communicative needs. Bypassing the role of the code in successful communication assigns decisive rights to abstract languages rather than to real-life language users, routinely leading to suspected or diagnosed speech-language disorder in academic and clinical assessment of multilingual children's communicative skills. This commentary reflects on whether code-driven assessment practices comply with the spirit of Article 19 of the Universal Declaration of Human Rights.

Markov Chain Analysis of Musical Dice Games

Volchenkov, D.; Dawin, J. R.

2012-07-01

A system for using dice to compose music randomly is known as the musical dice game. The discrete time MIDI models of 804 pieces of classical music written by 29 composers have been encoded into the transition matrices and studied by Markov chains. Contrary to human languages, entropy dominates over redundancy, in the musical dice games based on the compositions of classical music. The maximum complexity is achieved on the blocks consisting of just a few notes (8 notes, for the musical dice games generated over Bach's compositions). First passage times to notes can be used to resolve tonality and feature a composer.

Genetic biasing through cultural transmission: do simple Bayesian models of language evolution generalize?

Science.gov (United States)

Dediu, Dan

2009-08-07

The recent Bayesian approaches to language evolution and change seem to suggest that genetic biases can impact on the characteristics of language, but, at the same time, that its cultural transmission can partially free it from these same genetic constraints. One of the current debates centres on the striking differences between sampling and a posteriori maximising Bayesian learners, with the first converging on the prior bias while the latter allows a certain freedom to language evolution. The present paper shows that this difference disappears if populations more complex than a single teacher and a single learner are considered, with the resulting behaviours more similar to the sampler. This suggests that generalisations based on the language produced by Bayesian agents in such homogeneous single agent chains are not warranted. It is not clear which of the assumptions in such models are responsible, but these findings seem to support the rising concerns on the validity of the "acquisitionist" assumption, whereby the locus of language change and evolution is taken to be the first language acquirers (children) as opposed to the competent language users (the adults).

Full Text Available Objective: The aim of this comparative study was to evaluate the effects of radioactive pollution in river water and confounding risk factors on the prevalence of cardiovascular symptoms in people living in the Ural region. Methods: We selected this region as a case territory for study because it is exposed to chronic ionizing radiation. The area is composed of coastal localities situated along the Techa River, into which liquid radioactive waste materials have been released. As a control, we selected settlements that were not subjected to ionizing radiation. Results: We found a statistically significant relationship between radioactive contamination of a territory and the prevalence of pathologies of the cardiovascular systems of people living in the Techa riverside villages (OR=2.31, p<0.001. The influence of covariates (gender, age, overweight status, and others on the development of cardiovascular pathologies was analyzed. Some of these factors have been recognized as confounding factors. After accounting for confounding factors, the odds ratio for the impact of radiation on the prevalence of pathologies of the cardiovascular system decreased to (OR=1.58, p=0.02. Conclusions: Statistically significant gender and age differences were observed in the prevalence of pathologies of the cardiovascular system in residents of radioactively contaminated areas compared to residents of control areas. These differences show a more pronounced reaction to contamination in older residents, residents with an overweight status and residents with meteotropic reactions.

2018-03-02

Based on grey language multi-attribute group decision making, a kernel and grey scale scoring function is put forward according to the definition of grey language and the meaning of the kernel and grey scale. The function introduces grey scale into the decision-making method to avoid information distortion. This method is applied to the grey language hesitant fuzzy group decision making, and the grey correlation degree is used to sort the schemes. The effectiveness and practicability of the decision-making method are further verified by the industry chain sustainable development ability evaluation example of a circular economy. Moreover, its simplicity and feasibility are verified by comparing it with the traditional grey language decision-making method and the grey language hesitant fuzzy weighted arithmetic averaging (GLHWAA) operator integration method after determining the index weight based on the grey correlation.

Mapping of the vegetation (1:25000) of the Pre-Urals Steppe area at the Orenburg State Nature Reserve was completed in 2016. A map created with the geoinformation system contains 1931 simple and complex polygons for 25 types of vegetation. In a drought year, the average stock of palatable vegetation of the whole area is estimated at 8380 tons dry weight. The estimation is based on the size of areas covered by different types of vegetation, their grass production, the correction coefficients for decreasing of pasture forage stocks in winter and decreasing of production of grass communities in dry years. Based on pasture forage stocks the area could tolerate the maximum population size of 1769 individuals of the Przewalski horse, their average density could be 0.11 horse per ha. Yet, as watering places for animals are limited in Pre-Urals Steppe, grazing pressures on the vegetation next to the water sources may increase in dry years. That is why the above-mentioned calculated maximum population size and density must be reduced at least by half until some additional watering places are established and monitoring of the grazing effect on the vegetation next to the places is carried out regularly. Thus, the maximum size of the population is estimated at 800 to 900 individuals, which is almost 1.5 times more than necessary to establish a self-sustained population of the Przewalski horse.

Joint U.S./Russian studies of population exposures resulting from nuclear production activities in the southern Urals.

Beginning in 1948, the Soviet Union initiated a program for production of nuclear materials for a weapons program. The first facility for production of plutonium was constructed in the central portion of the country east of the southern Ural Mountains, about halfway between the major industrial cities of Ekaterinburg and Chelyabinsk. The facility, now known as the Mayak Production Association, and its associated town, now known as Ozersk, were built to irradiate uranium in reactors, separate the resulting plutonium in reprocessing plants, and prepare plutonium metal in the metallurgical plant. The rush to production, coupled with inexperience in handling radioactive materials, led to large radiation exposures, not only to the workers in the facilities, but also to the surrounding public. Fuel processing started with no controls on releases, and fuel dissolution and accidents in reactors resulted in release of ~37 PBq of I between 1948 and 1967. Designed disposals of low- and intermediate-level liquid radioactive wastes, and accidental releases via cooling water from tank farms of high-level liquid radioactive wastes into the small Techa River, caused significant contamination and exposures to residents of numerous small riverside villages downstream of the site. Discovery of the magnitude of the aquatic contamination in late 1951 caused revisions to the waste handling regimes, but not before over 200 PBq of radionuclides (with large contributions of Sr and Cs) were released. Liquid wastes were diverted to tiny Lake Karachay (which today holds over 4 EBq); cooling water was stopped in the tank farms. In 1957, one of the tanks in the tank farm overheated and exploded; over 70 PBq, disproportionately Sr, was blown over a large area to the northeast of the site. A large area was contaminated and many villages evacuated. This area today is known as the East Urals Radioactive Trace (EURT). Each of these releases was significant; together they have created a unique group

Hominin reliance on Oldowan stone tools-which appear from 2.5 mya and are believed to have been socially transmitted-has been hypothesized to have led to the evolution of teaching and language. Here we present an experiment investigating the efficacy of transmission of Oldowan tool-making skills along chains of adult human participants (N=184) using five different transmission mechanisms. Across six measures, transmission improves with teaching, and particularly with language, but not with imitation or emulation. Our results support the hypothesis that hominin reliance on stone tool-making generated selection for teaching and language, and imply that (i) low-fidelity social transmission, such as imitation/emulation, may have contributed to the ~700,000 year stasis of the Oldowan technocomplex, and (ii) teaching or proto-language may have been pre-requisites for the appearance of Acheulean technology. This work supports a gradual evolution of language, with simple symbolic communication preceding behavioural modernity by hundreds of thousands of years.

in a larger symbolic computational chain controlled by regions in the frontal parts of the brain. To Deacon, a symbolic learning algorithm drives language acquisition. The increase in size of the human brain in relation to the body may be due to a “cognitive arms race”. Both Pinker and Deacon agree......This article is a review of two contrastive views on the co-evolution of language and the brain – The Language Instinct by Steven Pinker (1994) and The Symbolic Species by Terrence Deacon (1997). As language is a trait unique to mankind it can not be equated with nonlinguistic communication – human...... or nonhuman. This points to a special human brain architecture. Pinker’s claim is that certain areas on the left side of the brain constitute a language organ and that language acquisition is instinctual. To Deacon, however, those areas are non-language-specific computational centers. Moreover, they are parts...

Methodology of reducing rock bump hazard during room and rillar mining of North Ural deep bauxite deposits

Directory of Open Access Journals (Sweden)

Д. В. Сидоров

2017-03-01

Full Text Available The article describes practical experience of using room and pillar mining (RAPM under conditions of deep horizons and dynamic overburden pressure. It was identified that methods of rock pressure control efficient at high horizons do not meet safety requirements when working at existing depths, that is explained by changes in geodynamic processes during mining. With deeper depth, the geodynamic processes become more intensive and number of pillar and roof failures increase. When working at 800 m the breakage of mine structures became massive and unpredictable, which paused a question of development and implementation of tools for compliance assessment of used elements of RAPM and mining, geological, technical and geodynamic conditions of North Ural bauxite deposits and further development of guidelines for safe mining under conditions of deep horizons and dynamic rock pressure.It describes reasons of mine structure failures in workings depending on natural and man-caused factors, determines possible hazards and objects of geomechanic support. It also includes compliance assessment of tools used for calculations of RAPM structures, forecast and measures for rock tectonic bursts at mines of OAO “Sevuralboksitruda” (SUBR. It describes modernization and development of new geomechanic support of RAPM considering natural and technogenic hazards. The article presents results of experimental testing of new parameters of RAPM construction elements of SUBR mines. It has data on industrial implementation of developed regulatory and guideline documents at these mines for identification of valid parameters of RAPM elements at deep depths.

Language Planning and Planned Languages: How Can Planned Languages Inform Language Planning?

Directory of Open Access Journals (Sweden)

Humphrey Tonkin

2015-04-01

Full Text Available The field of language planning (LP has largely ignored planned languages. Of classic descriptions of LP processes, only Tauli (preceded by Wüster suggests that planned languages (what Wüster calls Plansprache might bear on LP theory and practice. If LP aims "to modify the linguistic behaviour of some community for some reason," as Kaplan and Baldauf put it, creating a language de novo is little different. Language policy and planning are increasingly seen as more local and less official, and occasionally more international and cosmopolitan. Zamenhof's work on Esperanto provides extensive material, little studied, documenting the formation of the language and linking it particularly to issues of supranational LP. Defining LP decision-making, Kaplan & Baldauf begin with context and target population. Zamenhof's Esperanto came shortly before Ben-Yehuda's revived Hebrew. His target community was (mostly the world's educated elite; Ben-Yehuda's was worldwide Jewry. Both planners were driven not by linguistic interest but by sociopolitical ideology rooted in reaction to anti-Semitism and imbued with the idea of progress. Their territories had no boundaries, but were not imaginary. Function mattered as much as form (Haugen's terms, status as much as corpus. For Zamenhof, status planning involved emphasis on Esperanto's ownership by its community - a collective planning process embracing all speakers (cf. Hebrew. Corpus planning included a standardized European semantics, lexical selectivity based not simply on standardization but on representation, and the development of written, and literary, style. Esperanto was successful as linguistic system and community language, less as generally accepted lingua franca. Its terminology development and language cultivation offers a model for language revival, but Zamenhof's somewhat limited analysis of language economy left him unprepared to deal with language as power.

Full Text Available This paper purpose to explore the relationships between supply chain strategies and product performance in retail e-commerce. In this case, we concern that in current, in order to bear up under competition, organizations have to manage their supply chains so that they meet the needs of their final customers. With this concept in mind, the research presented in this study focuses on establishing the right strategy for supply chains according to their product segment. Thus, after a Literature Review, the paper explain a methodology based in different authors studies. Finally the article focuses on a pratical case in e-commerce retail that describes its application in this field. The research shows that it is possible to use a methodology for classifying supply chains using chain strategies and product features. The use of the right strategy for supply chains will improve the competitive advantage of businesses. One limitation is that the methodology study focuses on only two e-commerce segment; future studies may go further in refining the proposed framework for other segments. The aim of this research is to offer businesses a model for evaluating supply chains, allowing them to improve the performance of their products and services by using the right strategy for supply chains. The classification proposal of this paper presents an original model for classification of supply chains based on different studies on the theme.

The influence of edaphic and orographic factors on the formation of algal diversity in biological soil crusts was studied in mountain tundras of the Polar and Subpolar Urals. Bare spots developed in the soils on different parent materials and overgrown to different extents were investigated. Overall, 221 algal species from six divisions were identified. Among them, eighty-eight taxa were new for the region studied. The Stigonema minutum, S. ocellatum, Nostoc commune, Gloeocapsopsis magma, Scytonema hofmannii, Leptolyngbya foveolarum, Pseudococcomyxa simplex, Sporotetras polydermatica species and species of the Cylindrocystis, Elliptochloris, Fischerella, Leptosira, Leptolyngbya, Myrmecia, Mesotaenium, Phormidium, Schizothrix genera were permanent components of biological soil crusts. The basis of the algal cenoses in soil crusts was composed of cosmopolitan cyanoprokaryotes, multicellular green algae with thickened covers and abundant mucus. The share of nitrogen fixers was high. The physicochemical properties of primary soils forming under the crusts of spots are described. The more important factors affecting the species composition of algae in the crusts are the elevation gradient, temperature, soil moisture, and the contents of Ca, Mg, mobile phosphorus, and total nitrogen.

Entanglement in the harmonic chain and quantum fields

Full text: Relativistic field theory is a natural basis for the theoretical investigation of quantum entanglement, since the concept of locality and causality is inherently included. Vacuum entanglement of relativistic fields manifests itself in Hawking radiation and the Unruh effect. But it also is encountered in the linear harmonic chain, which - in the continuum limit and if generalized to three spatial dimensions - becomes the real scalar Klein-Gordon field. One can define average position and momentum operators for two separated blocks of oscillators in the harmonic chain and investigate the entanglement - by means of a separability criterion - between these blocks as a function of their distance and the coupling between the oscillators. This motivated us to rewrite the general separability conditions for continuous variables into the language of quantum field theory, where the position and momentum operator become integrals of the Klein-Gordon field and the conjugate momentum field, respectively. The role of the modes (or particles) is then merely played by the space(-time) regions over which the integration takes (author)

Programmability and verifiability lie at the heart of the software-defined networking paradigm. While OpenFlow and its match-action concept provide primitive operations to manipulate hardware configurations, over the last years, several more expressive network programming languages have been...... developed. This paper presents WNetKAT, the first network programming language accounting for the fact that networks are inherently weighted, and communications subject to capacity constraints (e.g., in terms of bandwidth) and costs (e.g., latency or monetary costs). WNetKAT is based on a syntactic...... generalize to more complex (and stateful) network functions and service chains. For example, WNetKAT allows to model flows which need to traverse certain waypoint functions, which can change the traffic rate.

The study of the rocks domanikoid type in the territory of the Ural-Volga region has an almost century-long history, beginning with the first studies of A.D. Archangelsky in the late 20's of last century. But nevertheless the question of the source of oil that formed the industrial deposits of Volga-Ural oil and gas province (OGP), where Romashkinskoye oil field occupies a special place, remains unresolved and topical. According to the sedimentary-migration theory of origin of oil and gas, it is supposed that the primary source of hydrocarbons in this area are the deposits of domanikoid type that contain a large ammount of sapropel organic matter (OM). Semiluki (domanik) horizon of srednefranski substage of the Upper Devonian is considered to be a typical domanikoid stratum. Investigation of the OM of the rocks and oils of the sedimentary cover on the basis of chromato-mass spectrometry method allows us to study the correlations between rock and oil and to assess the location (or absence) of the sources of hydrocarbons in the Paleozoic sedimentary cover. The results of geochemical study of dispersed organic matter (DOM) of rocks from Semiluksky horizon of the Upper Devonian and of the oil from Pashiysky horizon of the Middle Devonian form the basis of this paper. The objectives of this study were the following: to determine the original organic matter of the rocks, which would indicate the conditions of sedimentation of the supposed rock-oil sources; the study of chemofossils (biomarkers) in oil from Pashiyskiy horizon; and the identification of genetic association of DOM rocks from Semiluksky horizon with this oil on the basis of the oil-DOM correlation. The study of biomarkers was carried out with the help of chromato-mass spectrometry in the Laboratory of Geochemistry of Fossil Fuels (Kazan Federal University). In this study we used several informative parameters characterizing the depositional environment, the type of source OM and its maturity: STER / PENT, h

Enlarged symmetry algebras of spin chains, loop models, and S-matrices

International Nuclear Information System (INIS)

Read, N.; Saleur, H.

2007-01-01

The symmetry algebras of certain families of quantum spin chains are considered in detail. The simplest examples possess m states per site (m>=2), with nearest-neighbor interactions with U(m) symmetry, under which the sites transform alternately along the chain in the fundamental m and its conjugate representation m-bar. We find that these spin chains, even with arbitrary coefficients of these interactions, have a symmetry algebra A m much larger than U(m), which implies that the energy eigenstates fall into sectors that for open chains (i.e., free boundary conditions) can be labeled by j=0,1,...,L, for the 2L-site chain such that the degeneracies of all eigenvalues in the jth sector are generically the same and increase rapidly with j. For large j, these degeneracies are much larger than those that would be expected from the U(m) symmetry alone. The enlarged symmetry algebra A m (2L) consists of operators that commute in this space of states with the Temperley-Lieb algebra that is generated by the set of nearest-neighbor interaction terms; A m (2L) is not a Yangian. There are similar results for supersymmetric chains with gl(m+n|n) symmetry of nearest-neighbor interactions, and a richer representation structure for closed chains (i.e., periodic boundary conditions). The symmetries also apply to the loop models that can be obtained from the spin chains in a spacetime or transfer matrix picture. In the loop language, the symmetries arise because the loops cannot cross. We further define tensor products of representations (for the open chains) by joining chains end to end. The fusion rules for decomposing the tensor product of representations labeled j 1 and j 2 take the same form as the Clebsch-Gordan series for SU(2). This and other structures turn the symmetry algebra A m into a ribbon Hopf algebra, and we show that this is 'Morita equivalent' to the quantum group U q (sl 2 ) for m=q+q -1 . The open-chain results are extended to the cases vertical bar m vertical

This paper proposes a general method for incorporating rule-based constraints corresponding to regular languages into stochastic inference problems, thereby allowing for a unified representation of stochastic and syntactic pattern constraints. The authors' approach first established the formal connection of rules to Chomsky grammars, and generalizes the original work of Shannon on the encoding of rule-based channel sequences to Markov chains of maximum entropy. This maximum entropy probabilistic view leads to Gibb's representations with potentials which have their number of minima growing at precisely the exponential rate that the language of deterministically constrained sequences grow. These representations are coupled to stochastic diffusion algorithms, which sample the language-constrained sequences by visiting the energy minima according to the underlying Gibbs' probability law. The coupling to stochastic search methods yields the all-important practical result that fully parallel stochastic cellular automata may be derived to generate samples from the rule-based constraint sets. The production rules and neighborhood state structure of the language of sequences directly determines the necessary connection structures of the required parallel computing surface. Representations of this type have been mapped to the DAP-510 massively-parallel processor consisting of 1024 mesh-connected bit-serial processing elements for performing automated segmentation of electron-micrograph images.

Hierarchical processing in music, language, and action: Lashley revisited.

Science.gov (United States)

Fitch, W Tecumseh; Martins, Mauricio D

2014-05-01

Sixty years ago, Karl Lashley suggested that complex action sequences, from simple motor acts to language and music, are a fundamental but neglected aspect of neural function. Lashley demonstrated the inadequacy of then-standard models of associative chaining, positing a more flexible and generalized "syntax of action" necessary to encompass key aspects of language and music. He suggested that hierarchy in language and music builds upon a more basic sequential action system, and provided several concrete hypotheses about the nature of this system. Here, we review a diverse set of modern data concerning musical, linguistic, and other action processing, finding them largely consistent with an updated neuroanatomical version of Lashley's hypotheses. In particular, the lateral premotor cortex, including Broca's area, plays important roles in hierarchical processing in language, music, and at least some action sequences. Although the precise computational function of the lateral prefrontal regions in action syntax remains debated, Lashley's notion-that this cortical region implements a working-memory buffer or stack scannable by posterior and subcortical brain regions-is consistent with considerable experimental data. © 2014 The Authors.

2017-01-01

The aim of this paper is to examine the state of knowledge management research in supply chain management from three standpoints, methodological approach, supply chain management area, and knowledge management processes. Design/methodology/approach: To achieve this, a systematic review is conducted over the period 2000-2014 on the basis of a qualitative content analysis. Findings: Major results showed that knowledge management can be viewed as a leverage mechanism for: (i) supply chain integration; (ii) the enhancement of intra and inter-relations across the supply chain; (iii) supply chain strategy alignment; and (iv) the reinforcement of knowledge transfer in product development. Some supply chain management areas such as reverse logistics, inventory management, forecasting/demand planning, outsourcing, and risk management have been explored only to some extent. Furthermore, knowledge transfer is being studied in the majority of the articles, mainly by both case study and survey approach; mathematical models and simulation techniques are used in very limited articles. Findings concerning theoretical perspectives and managerial issues are also described. Research limitations/implications: The limitation of our study encompasses the aspects of search period (2000-2014), selection of search databases (Web of Science and SCOPUS and language selection (English). Practical implications: The exhibition of the KM processes within the SC context may help practitioners and managers interested in implementing KM initiatives to replicate the methodologies in order to increase the possibilities of a successful KM adoption. Originality/value: The systematic review will contribute to the understanding of the present state of research in the knowledge management theory, with focus on the supply chain, as there are no state-of-knowledge studies that report a systematic literature review approach.

About a quarter of young children in the United States are dual language learners. The large majority are Latino children who are exposed to Spanish in their homes. The language needs of Latino dual language preschoolers are different from the needs of monolingual English-speaking children. As a group, they are likely to live in environments that put them at risk of delays in language development. This situation is direr for dual language preschoolers with language impairment. Recent findings from studies on interventions for Spanish-English preschoolers with language impairment suggest that a bilingual approach does not delay English vocabulary and oral language learning and promotes Spanish maintenance. Targets and strategies for different language domains are described. The effects of pullout versus push-in interventions for this population are preliminarily explored.

Prerequisites and opportunities for repositioning of the Urals metallurgy within the Industry 4.0

Directory of Open Access Journals (Sweden)

O. A. Romanova

2017-12-01

Full Text Available The authors present the modern trends in the development of metallurgy, and classify the technological structure of metallurgical industry. The article contains specific features of the development of metallurgy in the conditions of industry formation. A special role in this process plays the pace of digitalization and robotization of the industry, the development of additive technologies, Internet of things. The authors substantiate the possibility of developing the metallurgy of the Middle Urals as a science-intensive, high-tech complex that meets the requirements of Industry 4.0. This possibility interrelates with its repositioning, one of the main tasks of which is the formation of new sales markets focused on high-tech consumer industries, as well as the preservation of traditional consumption sectors under conditions of increasing competition in the construction materials market. The authors underline the importance of international cooperation in the field of environmentally safe industrial development, with applying the best available technologies and innovative development in general. The authors propose a methodological approach for assessing the repositioning of the regional metallurgical complex. This approach is the consecutive implementation of the following stages: assessment of dynamics and the forecast of development of consumer steel products sector and its structure based on identified priority areas of technological development of metallurgy in the region; construction of a factor model describing the changes in parameters of the RMC repositioning process, and approximation of the characteristics of their nonlinear elements; building a mathematical model on the basis of neural network algorithms for assessing the process of repositioning the RMC, taking into account projected values of the RMK parameters in the process of repositioning and changing the structure of consumer markets for metal products; formation of a variable

Iron marketing and modernisation in the Urals in XIX century: evident and implicit links

2011-06-01

Full Text Available Modernization theory, interpreted as a civilizational shift from traditional agrarian to a modern industrial society, allows considering innovations as the conditions necessary and sufficient for this transformation. Russia of the XIX century was characterized by similar processes. The transition to the new industrial technology foundation began decades before the abolition of serfdom. This paper tells about the experience of modernization of metallurgical production at Nizhny Tagil plants of Demidovs in 1840-1850. It is noted that export orientation of iron and steel in Western Europe played a powerful incentive to improve the technical and technological base of the mountain plants of the Middle Urals. Also important is the fact that the Demidovs administration has sought means to minimize the number of intermediaries in the sale of their products. The administration has sought ways to help commissioners get responses back from direct consumers of iron produced in Nizhny Tagil plants. Demidovs were interested, as they assessed the quality of the metal, which "internal properties" they would like to see in their iron in order to successfully use it in the production process. In turn, the domestic market was practicing somewhat different approach to trading metals - a network of regional sales offices in most major economic centers was functioning to better know the requirements for the quality of the metal and the volume of its production plan in line with the real needs of specific types of iron and copper. At the same time, the contradictory nature of the modernization process itself, in particular, the reluctance of the management of enterprises pass on the use of coal as a primary fuel source is highlighted. In fact, the use of coal Nizhny Tagil plants began to implement only in 1880, which did not stop Demidovs during the post-reform period to increase volumes of metal smelting on the old industrial-energy base.

Trans-cult-ural fandom: Desire, technology and the transformation of fan subjectivities in the Japanese female fandom of Hong Kong stars

Directory of Open Access Journals (Sweden)

Lori Hitchcock Morimoto

2013-09-01

Full Text Available This essay examines the ways in which affective desire and new media technologies were mobilized by Japanese female fans of Hong Kong films and stars to produce a fan subjectivity that was at once cult and transcultural. The origins of this fandom, which flourished from around 1985 through the 1990s, lay in structural affinities of the Japanese and Hong Kong entertainment industries of the 1980s, as well as the ways in which popular stars of both places were expected to perform their stardom. In particular, a shared valuing of stars' relatability and approachability translated, for Japanese fans, into a seemingly paradoxical sense of intimacy with the stars of another culture, an intimacy that was fostered and heightened by women's pursuit of Hong Kong media outside the official distribution channels of the Japanese media industry. I examine the knowledges required by women to seek out favorite stars' films on VHS and VCD, as well as the sites of such consumption, which combined in the production of what I tentatively term a trans-cult-ural fan subjectivity that was at once cultish in its intensity and desire for ownership, as well as transcultural in its performance by fans.

Structural Change of Gross Regional Product in the Subjects of Ural Federal District

Valeriy Vladimirovich Gamukin

2017-06-01

Full Text Available The important factor of the stability of the national economy is the adaptive capability of regional economies to damping of external and internal factors of risk. It occurs thanks to the variety of the developed industry structures of the economy in regions as well as to the constant process of their transformation that finds reflection in the structure of the gross regional product (GRP. It is possible to consider three main strategies of the development of the structure of regional economy: 1 the reduction of the economies of regions to the balanced condition; 2 the emphasis on the individualization of the structure of regional economy; 3 the combined strategy, when regions with various structure of economy are integrated into macro-regions in which there is a compilation of structure. In the latter case, this can result in both the leveling of the GRP structure of the territorial subjects of the Russian Federation included in the region and its convergence to macro-region indicators, in general (for example, to the federal district’s indicators. For the confirmation of this hypothesis, the analysis of GRP of the subjects included in the Ural Federal District for the period of 2005–2014 is carried out. As a result, a number of conclusions are formulated. Thus, the measurements with the use of the Ryabtsev Index and Szalai Index have shown that the GRP structure of autonomous areas is most close to the GRP structure of the federal district. At the same time, during the analyzed period, there was a reducing in a share of mining operations along with the increase in a share of GRP types referred to the auxiliary and social component of economic activity. In the federal district, there is a slow movement to a more balanced participation of regions of the district in the generation of GRP total amount. When using the author’s index of the structure determined by the double calculation of the sum of squared deviations, the tendency towards

Recently, an Irradiator BATAN 2X250 k Curie for agricultural product is under design. The installation is provided by the gamma source about 2x250 k Curie. Agricultural products are carried into carriers and these carriers are hanged on the conveyor chain. The chain moves into a radiation chamber following the trajectoire. The chain is drived by motor. For this reason, the calculation is performed to determine the motor power. After resolving the force equilibrium equation, the force and power of the motor needed to drive the chain are obtained. Numerical method by using V Basic language is used to resolve the equation. The calculation result shows the correlation between friction coefficient and motor power. From the evaluation, it is decided that the friction coefficient should be less than 0,015. By this friction, the motor power is about 3. 13 k Watt. From the evaluation, it is also obtained that the radius of the curve trajectory shall not be too small. Combination between high friction and small curve radius could lead to the locked condition in which high power motor are not be able to move the conveyor chain). (author)

The Paleolithic Continuity Paradigm for the origins of Indo-European languages dated back to 1990s, but it has not been widely accepted by the international academic community for different reasons. And the Chinese academic community is also unfamiliar with its progress, hypotheses, historical reconstruction and objectives. It overthrew the Catastrophism, Eurocentrism, and Racism in the previous IE theories, removed misinterpretations of Darwinism in the linguistic circle, inherited and developed the Uralic Continuity Theory, and presented seminal viewpoints on the nature of changes in language, ways of lexical periodicalization and the relationship between linguistic frontiers and archaeological frontiers. Therefore, it deserves to be popularized as a new paradigm for origins of Indo-European languages and a prospective general framework applicable to all domains that find a direct or indirect expression in language.%　　印欧语言起源研究的旧石器连续范式发端于20世纪90年代，但尚未被国际主流学术界广泛接纳，其发展历程、理论假设、历史重构及理论目标尚不为国内学界了解。它摒弃了传统理论中的“突变论”“欧洲中心主义”和“种族主义”，修正了传统理论对达尔文进化论的误解，继承并发展了“乌拉尔连续理论”，提出了关于语言变化、词汇历史分期方法、语言边界与考古边界的关系等方面的新观点，值得借鉴和推广。

The Linguistic Interpretation for Language Union – Language Family

Directory of Open Access Journals (Sweden)

E.A. Balalykina

2016-10-01

Full Text Available The paper is dedicated to the problem of determination of the essence of language union and language family in modern linguistics, which is considered important, because these terms are often used as absolute synonyms. The research is relevant due to the need to distinguish the features of languages that are inherited during their functioning within either language union or language family when these languages are compared. The research has been carried out in order to present the historical background of the problem and to justify the need for differentiation of language facts that allow relating languages to particular language union or language family. In order to fulfill the goal of this work, descriptive, comparative, and historical methods have been used. A range of examples has been provided to prove that some languages, mainly Slavonic and Baltic languages, form a language family rather than a language union, because a whole number of features in their systems are the heritage of their common Indo-European past. Firstly, it is necessary to take into account changes having either common or different nature in the system of particular languages; secondly, one must have a precise idea of what features in the phonetic and morphological systems of compared languages allow to relate them to language union or language family; thirdly, it must be determined whether the changes in compared languages are regular or of any other type. On the basis of the obtained results, the following conclusions have been drawn: language union and language family are two different types of relations between modern languages; they allow identifying both degree of similarity of these languages and causes of differences between them. It is most important that one should distinguish and describe the specific features of two basic groups of languages forming language family or language union. The results obtained during the analysis are very important for linguistics

Falling chains

OpenAIRE

Wong, Chun Wa; Yasui, Kosuke

2005-01-01

The one-dimensional fall of a folded chain with one end suspended from a rigid support and a chain falling from a resting heap on a table is studied. Because their Lagrangians contain no explicit time dependence, the falling chains are conservative systems. Their equations of motion are shown to contain a term that enforces energy conservation when masses are transferred between subchains. We show that Cayley's 1857 energy nonconserving solution for a chain falling from a resting heap is inco...

2014-01-01

Full Text Available We reviewed 153 peer-reviewed sources to provide identification of modern supply chain management techniques and exploration of supply chain modeling, to offer decision support to managers. Ultimately, the review is intended to assist member-companies of supply chains, mainly producers, improve their current management approaches, by directing them to studies that may be suitable for direct application to their supply chains and value chains for improved efficiency and profitability. We found that information on supply chain management and modeling techniques in general is available. However, few Canadian-based published studies exist regarding a demand-driven modeling approach to value/supply chain management for wood pellet production. Only three papers were found specifically on wood pellet value chain analysis. We propose that more studies should be carried out on the value chain of wood pellet manufacturing, as well as demand-driven management and modeling approaches with improved demand forecasting methods.

How language production shapes language form and comprehension

Directory of Open Access Journals (Sweden)

Maryellen C MacDonald

2013-04-01

Full Text Available Language production processes can provide insight into how language comprehension works and language typology—why languages tend to have certain characteristics more often than others. Drawing on work in memory retrieval, motor planning, and serial order in action planning, the Production-Distribution-Comprehension (PDC account links work in the fields of language production, typology, and comprehension: 1 faced with substantial computational burdens of planning and producing utterances, language producers implicitly follow three biases in utterance planning that promote word order choices that reduce these burdens, thereby improving production fluency. 2 These choices, repeated over many utterances and individuals, shape the distributions of utterance forms in language. The claim that language form stems in large degree from producers’ attempts to mitigate utterance planning difficulty is contrasted with alternative accounts in which form is driven by language use more broadly, language acquisition processes, or producers’ attempts to create language forms that are easily understood by comprehenders. 3 Language perceivers implicitly learn the statistical regularities in their linguistic input, and they use this prior experience to guide comprehension of subsequent language. In particular, they learn to predict the sequential structure of linguistic signals, based on the statistics of previously-encountered input. Thus key aspects of comprehension behavior are tied to lexico-syntactic statistics in the language, which in turn derive from utterance planning biases promoting production of comparatively easy utterance forms over more difficult ones. This approach contrasts with classic theories in which comprehension behaviors are attributed to innate design features of the language comprehension system and associated working memory. The PDC instead links basic features of comprehension to a different source: production processes that shape

This article addresses the problem in which a chain falls from a glass from some height. This phenomenon demonstrates a paradoxical rise of the chain over the glass. To explain this effect, an initial hypothesis and an appropriate theory are proposed for calculating the steady fall parameters of the chain. For this purpose, the modified Cayley's problem of falling chain given its rise due to the centrifugal force of upward inertia is solved. Results show that the lift caused by an increase in linear density at the part of chain where it is being bent (the upper part) is due to the convergence of the chain balls to one another. The experiments confirm the obtained estimates of the lifting chain.

Haplotype frequencies at the DRD2 locus in populations of the East European Plain

2009-09-01

Full Text Available Abstract 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.

Eco-logo-genetical characteristic of seed progeny of the Taraxacum officinale S.L. from the zone of east-ural radioactive trace

2004-01-01

Levels of soil contamination with 90 Sr and 137 Cs radionuclides within the zone of Eastern-Ural radioactive trace, at the plots differently distant from the place of Kyshtym accident of 1957, exceed values of the global level 4-40 times. It was shown that the same coeno-population from EURT in the different years revealed the whole variety of previously described low-level irradiation effects. They are: stimulating one (vitality indexes in seed progeny exceed significantly those registered in the background samples); the depressing one, marked for high mortality level; and an indifferent effect showing neither significant differences from the background plants. Variation scope exceeding the normal one in regard to plants growth and development rates, as well as high frequencies of chromosome and morphological aberrations indicate to the plant genome non-stability caused by chronic low-level irradiation loads. Seed progeny also demonstrated the similar ambiguous response to additional irradiation, which is confirmed by allozyme analysis results. Standard electrophoretic methods are applicable to the dandelion studies. Some enzyme systems (Got, Dia) seem to be more suitable for seedlings, whereas the others provided satisfactory results being used for the seed material. In plant coeno-populations situated in radionuclides-polluted zone, genomic recombination processes show higher intensity. High enzymatic variability provides the material for natural selection and increase the adaptive potential of coeno-populations. (author)

Kathryn M. Howard

2009-08-01

Full Text Available This article focuses on surveys of first-year language learners studying 19 different languages at two large East Coast Universities. The survey included questions about why students decided to study these languages, including career plans, study abroad, interest in liter-ature and culture, desire to communicate with speakers of the lan-guage, desire to speak with family members, building on previous language skills, and love of languages in general. Results were broken down by language and by language types, such as whether the lan-guages were commonly taught in the United States, how the lan-guages are politicized in the current historical context, and how the languages intersect with historical and geographic trends in immigra-tion and immigration policy. This article examines in particular the presence of heritage language learners in these language classrooms, the varying reasons that students choose to study these languages, and students’ prior attainment and exposure to the language. The pa-per discusses the political, historical, and social contexts of language study in the United States and the associated implications for effec-tive language recruitment and effective language program design.

Multi-chain Markov chain Monte Carlo methods for computationally expensive models

Science.gov (United States)

Huang, M.; Ray, J.; Ren, H.; Hou, Z.; Bao, J.

2017-12-01

Markov chain Monte Carlo (MCMC) methods are used to infer model parameters from observational data. The parameters are inferred as probability densities, thus capturing estimation error due to sparsity of the data, and the shortcomings of the model. Multiple communicating chains executing the MCMC method have the potential to explore the parameter space better, and conceivably accelerate the convergence to the final distribution. We present results from tests conducted with the multi-chain method to show how the acceleration occurs i.e., for loose convergence tolerances, the multiple chains do not make much of a difference. The ensemble of chains also seems to have the ability to accelerate the convergence of a few chains that might start from suboptimal starting points. Finally, we show the performance of the chains in the estimation of O(10) parameters using computationally expensive forward models such as the Community Land Model, where the sampling burden is distributed over multiple chains.

Through the integration of theoretical perspectives, the authors highlight both the economic and socio-cultural elements that impinge on the performance of these networks. This enables them to consider the tensions, synergies and contradictions between market logics and local socio-cultural practices, meanings and values. Drawing lessons from the cases, the authors aim to contribute to the theoretical discussion on how (inclusive value chains are socially and economically constructed, and how their performance is related to innovation networks. /* Style Definitions */ table.MsoNormalTable {mso-style-name:"Tabla normal"; mso-tstyle-rowband-size:0; mso-tstyle-colband-size:0; mso-style-noshow:yes; mso-style-priority:99; mso-style-parent:""; mso-padding-alt:0cm 5.4pt 0cm 5.4pt; mso-para-margin:0cm; mso-para-margin-bottom:.0001pt; mso-pagination:widow-orphan; font-size:10.0pt; font-family:"Times New Roman","serif"; mso-ansi-language:ES-CO; mso-fareast-language:ES-CO;}

Brentari, Diane; Coppola, Marie

2013-03-01

How do languages emerge? What are the necessary ingredients and circumstances that permit new languages to form? Various researchers within the disciplines of primatology, anthropology, psychology, and linguistics have offered different answers to this question depending on their perspective. Language acquisition, language evolution, primate communication, and the study of spoken varieties of pidgin and creoles address these issues, but in this article we describe a relatively new and important area that contributes to our understanding of language creation and emergence. Three types of communication systems that use the hands and body to communicate will be the focus of this article: gesture, homesign systems, and sign languages. The focus of this article is to explain why mapping the path from gesture to homesign to sign language has become an important research topic for understanding language emergence, not only for the field of sign languages, but also for language in general.

Patients must be able to feel as much trust for caregivers and the healthcare system at the healthcare centre as at the emergency department. The aim of this study is to explain and understand the phenomenon of trust in the early chain of healthcare, when a patient has called an ambulance for a non-urgent condition and been referred to the healthcare centre. A lifeworld hermeneutic approach from the perspective of caring science was used. Ten patients participated: seven female and three male. The setting is the early chain of healthcare in south-western Sweden. The findings show that the phenomenon of trust does not automatically involve medical care. However, attention to the patient's lifeworld in a professional caring relationship enables the patient to trust the caregiver and the healthcare environment. It is clear that the "voice of the lifeworld" enables the patient to feel trust. Trust in the early chain of healthcare entails caregivers' ability to pay attention to both medical and existential issues in compliance with the patient's information and questions. Thus, the patient must be invited to participate in assessments and decisions concerning his or her own healthcare, in a credible manner and using everyday language.

THE INFLUENCE OF LANGUAGE USE AND LANGUAGE ATTITUDE ON THE MAINTENANCE OF COMMUNITY LANGUAGES SPOKEN BY MIGRANT STUDENTS

Directory of Open Access Journals (Sweden)

Leni Amalia Suek

2014-05-01

Full Text Available The maintenance of community languages of migrant students is heavily determined by language use and language attitudes. The superiority of a dominant language over a community language contributes to attitudes of migrant students toward their native languages. When they perceive their native languages as unimportant language, they will reduce the frequency of using that language even though at home domain. Solutions provided for a problem of maintaining community languages should be related to language use and attitudes of community languages, which are developed mostly in two important domains, school and family. Hence, the valorization of community language should be promoted not only in family but also school domains. Several programs such as community language school and community language program can be used for migrant students to practice and use their native languages. Since educational resources such as class session, teachers and government support are limited; family plays significant roles to stimulate positive attitudes toward community language and also to develop the use of native languages.

Sparks, R; Ganschow, L; Pohlman, J; Skinner, S; Artzer, M

1992-12-01

Research findings suggest that most students who have foreign language learning problems have language-based difficulties and, in particular, phonological processing problems. Authors of the present study examined pre- and posttest scores on native language and foreign language aptitude tests of three groups of at-risk high school students enrolled in special, self-contained sections of first-year Spanish. Two groups were instructed using a multisensory structured language (MSL) approach. One of the groups was taught in both English and Spanish (MSL/ES), the other only in Spanish (MSL/S). The third group (NO-MSL) was instructed using more traditional second language teaching methodologies. Significant gains were made by the MSL-ES group on measures of native language phonology, vocabulary, and verbal memory and on a test of foreign language aptitude; the MSL/S group made significant gains on the test of foreign language aptitude. No significant gains on the native language or foreign language aptitude measures were made by the NO-MSL group. Implications for foreign language classroom instruction of at-risk students are discussed.

Bilinguals' Existing Languages Benefit Vocabulary Learning in a Third Language.

Science.gov (United States)

Bartolotti, James; Marian, Viorica

2017-03-01

Learning a new language involves substantial vocabulary acquisition. Learners can accelerate this process by relying on words with native-language overlap, such as cognates. For bilingual third language learners, it is necessary to determine how their two existing languages interact during novel language learning. A scaffolding account predicts transfer from either language for individual words, whereas an accumulation account predicts cumulative transfer from both languages. To compare these accounts, twenty English-German bilingual adults were taught an artificial language containing 48 novel written words that varied orthogonally in English and German wordlikeness (neighborhood size and orthotactic probability). Wordlikeness in each language improved word production accuracy, and similarity to one language provided the same benefit as dual-language overlap. In addition, participants' memory for novel words was affected by the statistical distributions of letters in the novel language. Results indicate that bilinguals utilize both languages during third language acquisition, supporting a scaffolding learning model.

In contrast with the earlier work of Flory, no simplifying assumption on the wave vector dependence of the effective potential between segments is made. In order to obtain a closed form expression for the dimension of the long chain, we first derive a general expression for the mean square end-to-end distance of a flexible chain with arbitr...

Pozolotina, Vera N; Antonova, Elena V

2017-03-01

The multiple stressors, in different combinations, may impact differently upon seed quality, and low-level doses of radiation may enhance synergistic or antagonistic effects. During 1991-2014 we investigated the quality of the dandelion (Taraxacum officinale s.l.) seed progeny growing under low-level radiation exposure at the East-Ural Radioactive Trace (EURT) area (result of the Kyshtym accident, Russia), and in plants from areas exposed to background radiation. The viability of the dandelion seed progeny was assessed according to chronic radiation exposure, accounting for the variability of weather conditions among years. Environmental factors (temperature, precipitation, and their ratio in different months) can modify the radiobiological effects. We found a wide range of possible responses to multiple stressors: inhibition, stimulation, and indifferent effects in different seasons. The intraspecific variability of the quality of dandelion seed progeny was greatly increased under conditions of low doses of chronic irradiation. Temperature was the most significant factor for seed progeny formation in the EURT zone, whereas the sums of precipitation and ratios of precipitation to temperature dominantly affected organisms from the background population.

Ferjan Ramirez, Naja; Leonard, Matthew K; Davenport, Tristan S; Torres, Christina; Halgren, Eric; Mayberry, Rachel I

2016-03-01

One key question in neurolinguistics is the extent to which the neural processing system for language requires linguistic experience during early life to develop fully. We conducted a longitudinal anatomically constrained magnetoencephalography (aMEG) analysis of lexico-semantic processing in 2 deaf adolescents who had no sustained language input until 14 years of age, when they became fully immersed in American Sign Language. After 2 to 3 years of language, the adolescents' neural responses to signed words were highly atypical, localizing mainly to right dorsal frontoparietal regions and often responding more strongly to semantically primed words (Ferjan Ramirez N, Leonard MK, Torres C, Hatrak M, Halgren E, Mayberry RI. 2014. Neural language processing in adolescent first-language learners. Cereb Cortex. 24 (10): 2772-2783). Here, we show that after an additional 15 months of language experience, the adolescents' neural responses remained atypical in terms of polarity. While their responses to less familiar signed words still showed atypical localization patterns, the localization of responses to highly familiar signed words became more concentrated in the left perisylvian language network. Our findings suggest that the timing of language experience affects the organization of neural language processing; however, even in adolescence, language representation in the human brain continues to evolve with experience. © The Author 2014.

Ubiquitination is the most versatile posttranslational modification. The information is encoded by linkage type as well as chain length, which are translated by ubiquitin binding domains into specific signaling events. Chain topology determines the conformational space of a ubiquitin chain and adds an additional regulatory layer to this ubiquitin code. In particular, processes that modify chain length will be affected by chain conformations as they require access to the elongation or cleavage sites. We investigated conformational distributions in the context of chain elongation and disassembly using pulsed electron-electron double resonance spectroscopy in combination with molecular modeling. Analysis of the conformational space of diubiquitin revealed conformational selection or remodeling as mechanisms for chain recognition during elongation or hydrolysis, respectively. Chain elongation to tetraubiquitin increases the sampled conformational space, suggesting that a high intrinsic flexibility of K48-linked chains may contribute to efficient proteasomal degradation.

CHAIN 2

International Nuclear Information System (INIS)

Bailey, D.

1998-04-01

The Second Processing Chain (CHAIN2) consists of a suite of ten programs which together provide a full local analysis of the bulk plasma physics within the JET Tokamak. In discussing these ten computational models this report is intended to fulfil two broad purposes. Firstly it is meant to be used as a reference source for any user of CHAIN2 data, and secondly it provides a basic User Manual sufficient to instruct anyone in running the CHAIN2 suite of codes. In the main report text each module is described in terms of its underlying physics and any associated assumptions or limitations, whilst deliberate emphasis is put on highlighting the physics and mathematics of the calculations required in deriving each individual datatype in the standard module PPF output. In fact each datatype of the CHAIN2 PPF output listed in Appendix D is cross referenced to the point in the main text where its evaluation is discussed. An effort is made not only to give the equation used to derive a particular data profile but also to explicitly define which external data sources are involved in the computational calculation

Particular attention is paid to the role of the organizational and managerial component affecting usage performance of infrastructure objects and including regulation of the institutions of social infrastructure, planning and software. The purpose of the study is to evaluate the effectiveness of management of social infrastructure through the conjugation of immediate results (the dynamics of indicators of social services and outcomes (parameters of the quality of life of the population. The hypothesis of the study was the violation of the principle of infra-systematicity in the infrastructural support of the improvement of the quality of life in the Russian regions, due to the lack of effectiveness of public administration. In the study, the following methodological approaches are used: structural, factoral, systematic and evolutionary approaches to justify the conception, develop methodology and determine the impact of changes in the parameters of social infrastructure availability for the provided services, shifts in indexes of quality of life. The paper proposes the quantitative evaluation of the effectiveness of organizational management based on the diagnosis of the adequacy of the implementation of the principle of infra-systematicity in the functioning of social infrastructure on the basis of the elasticity coefficient. The proposed approach and the received analytical data on health, education, commerce, housing, culture and sport fields have allowed to range the regions of the Ural Federal District and highlight the areas of insufficient effectiveness of the organizational and management tool for improvement of life quality. The findings of the research may serve as a core for practical recommendations for executive bodies of administrative units of

Since 1996, the Ural Electrochemical Integrated Plant (UEIP) located in the town of Novouralsk, Russia, (previously known as Sverdlovsk-44) and the United States Department of Energy (U.S. DOE) have been cooperating under the Nuclear Material Protection, Control and Accounting (MPC and A) Program. Because UEIP is involved in the processing of highly enriched uranium (HEU) into low enriched uranium (LEU), and there are highly enriched nuclear materials on its territory, the main goal of the MPC and A cooperation is to upgrade those systems that ensure secure storage, processing and transportation of nuclear materials at the plant. UEIP has completed key upgrades (equipment procurement and installation) aimed at improving MPC and A systems through significant investments made by both the U.S. DOE and UEIP. These joint cooperative efforts resulted in bringing MPC and A systems into compliance with current regulations, which led to nuclear material (NM) theft risk reduction and prevention from other unlawful actions with respect to them. Upon the U.S. MPC and A project team's suggestion, UEIP has developed an equipment inventory control process to track all the property provided through the MPC and A Program. The UEIP process and system for managing equipment provides many benefits including: greater ease and efficiency in determining the quantities, location, maintenance and repair schedule for equipment; greater assurance that MPC and A equipment is in continued satisfactory operation; and improved control in the development of a site sustainability program. While emphasizing UEIP's equipment inventory control processes, this paper will present process requirements and a methodology that may have practical and helpful applications at other sites.

Competing Desires and Realities: Language Policies in the French-Language Classroom

Directory of Open Access Journals (Sweden)

Angela Giovanangeli

2009-03-01

Full Text Available French language policy has historically centred on ways French can be considered a dominant and influential language. It has done this since the Middle Ages, by allowing the French language to serve as a political tool. On an international level, language was a way of subjugating conquered peoples (former colonies. It promoted France’s international status (by the 18th century French was the diplomatic language of Europe. On a national level, the French language was one of the ways governments were able to centralise political power (suppression of regional languages. One of the ways French language authorities have promoted the use of language has been through education policies and the way language is taught in schools. For example, the French language was imposed on the colonised territories of France through teaching in missionary schools. Within France, stringent laws were adopted, in particular during the nineteenth century, allowing the French language to replace local languages in schools. In France today, language policies continue to exist and to have an influence on the way we view language and society. One of the main priorities of French language policy is to protect the status of the national language in particular with respect to the increasing use of English as a global dominant language in areas such as science, technology, tourism, entertainment and the media (Nunan: 2007, 178. Consequently, France has adopted policies to respond to this linguistic climate. This has implications on the way the French language is taught both within France as well as outside of France. This paper will examine some of the policies and agencies created over recent years that affect the French language. It will also identify some of the consequences these policies have on the teaching of language. Finally it will argue that a space has been created within the language classroom that attempts to find a compromise between the language policies of

"Real Language": Combining Intermediate Spanish Language Learners and ESOL/Native Speakers for Vernacular Language Acquisition

Directory of Open Access Journals (Sweden)

Joe LaValle

2017-06-01

Full Text Available This paper addresses the possibilities of combining Spanish language learners and English language learners in high school and post-secondary institutions for mutual benefit to learn authentic language. Academic or "classroom" Spanish is insufficient to empower students for today's workplace. The concept behind "Real Language" is illustrated by an example of an interdisciplinary activity to facilitate communicative interaction in genuine language and promote cultural understanding between intermediate Spanish students and ESOL/native speakers at the high school and post-secondary level. Students are asked to utilize their life skills in interactive, freestyle conversation without the intervention of an instructor. The learning space for language exchange is an out-of-class venue for a non-intimidating, more authentic setting. This simple qualitative study investigates the potential value of this sort of interdisciplinary activity. The intent is to evaluate attitudes of the participants in relation to confidence in their ability to use the target language, and their willingness to use it in social and professional environments and, in addition, to facilitate cultural understanding. The positive result of the project is validated by the voice of the student participants as they reflect on their experience in "Real Language". Could this concept facilitate evolving strategies for interdisciplinary contemporary foreign language learning?

2017-01-01

Full Text Available A systematic review of literature up to date reflects great scholarly interest in the impacts of study abroad (SA sojourns on foreign language learners’ communicative competence. This paper provides an overview on gains in sociolinguistic and pragmatic competences drawing upon research carried out in this field, which in broad terms supports the belief that both types of competences are effectively developed in SA stays. This article also offers a detailed account of the main constituents of the language tourism product -the travel component and the language learning component- with a special focus on the educational input and the language learning complements included in the latter. Thus, a fundamental part of the language tourism market system will be depicted from a supply perspective. Following an exploratory approach, a literature review was conducted in order to identify existing and missing knowledge in the field of language travel supply, and key aspects were pinpointed and classified. The taxonomy and underpinning concepts resulting from the categorisation of those key features may be considered the starting point for future investigations on SA programmes. The model offered in this exploratory study aims at constituting the underlying conceptual framework for subsequent research on the role of different SA programme design characteristics within the language tourism experience.

Language Networks as Models of Cognition: Understanding Cognition through Language

Science.gov (United States)

Beckage, Nicole M.; Colunga, Eliana

Language is inherently cognitive and distinctly human. Separating the object of language from the human mind that processes and creates language fails to capture the full language system. Linguistics traditionally has focused on the study of language as a static representation, removed from the human mind. Network analysis has traditionally been focused on the properties and structure that emerge from network representations. Both disciplines could gain from looking at language as a cognitive process. In contrast, psycholinguistic research has focused on the process of language without committing to a representation. However, by considering language networks as approximations of the cognitive system we can take the strength of each of these approaches to study human performance and cognition as related to language. This paper reviews research showcasing the contributions of network science to the study of language. Specifically, we focus on the interplay of cognition and language as captured by a network representation. To this end, we review different types of language network representations before considering the influence of global level network features. We continue by considering human performance in relation to network structure and conclude with theoretical network models that offer potential and testable explanations of cognitive and linguistic phenomena.

The atomic chains are composed of dimers that have their bonds aligned in a direction parallel to the chain direction. At low temperatures the atomic chains undergo a Peierls transition: the periodicity of the chains doubles from a 2 x to a 4 x periodicity and an energy gap opens up. Furthermore, at low temperatures (T<80 K) novel quasi-one-dimensional electronic states are found. These quasi-one-dimensional electronic states originate from an electronic state of the underlying terrace that is confined between the atomic chains.

Evolution: Language Use and the Evolution of Languages

Science.gov (United States)

Croft, William

Language change can be understood as an evolutionary process. Language change occurs at two different timescales, corresponding to the two steps of the evolutionary process. The first timescale is very short, namely, the production of an utterance: this is where linguistic structures are replicated and language variation is generated. The second timescale is (or can be) very long, namely, the propagation of linguistic variants in the speech community: this is where certain variants are selected over others. At both timescales, the evolutionary process is driven by social interaction and the role language plays in it. An understanding of social interaction at the micro-level—face-to-face interactions—and at the macro-level—the structure of speech communities—gives us the basis for understanding the generation and propagation of language structures, and understanding the nature of language itself.

Modeling Coevolution between Language and Memory Capacity during Language Origin

Science.gov (United States)

Gong, Tao; Shuai, Lan

2015-01-01

Memory is essential to many cognitive tasks including language. Apart from empirical studies of memory effects on language acquisition and use, there lack sufficient evolutionary explorations on whether a high level of memory capacity is prerequisite for language and whether language origin could influence memory capacity. In line with evolutionary theories that natural selection refined language-related cognitive abilities, we advocated a coevolution scenario between language and memory capacity, which incorporated the genetic transmission of individual memory capacity, cultural transmission of idiolects, and natural and cultural selections on individual reproduction and language teaching. To illustrate the coevolution dynamics, we adopted a multi-agent computational model simulating the emergence of lexical items and simple syntax through iterated communications. Simulations showed that: along with the origin of a communal language, an initially-low memory capacity for acquired linguistic knowledge was boosted; and such coherent increase in linguistic understandability and memory capacities reflected a language-memory coevolution; and such coevolution stopped till memory capacities became sufficient for language communications. Statistical analyses revealed that the coevolution was realized mainly by natural selection based on individual communicative success in cultural transmissions. This work elaborated the biology-culture parallelism of language evolution, demonstrated the driving force of culturally-constituted factors for natural selection of individual cognitive abilities, and suggested that the degree difference in language-related cognitive abilities between humans and nonhuman animals could result from a coevolution with language.

Document Categorization with Modified Statistical Language Models for Agglutinative Languages

Directory of Open Access Journals (Sweden)

Tantug

2010-11-01

Full Text Available In this paper, we investigate the document categorization task with statistical language models. Our study mainly focuses on categorization of documents in agglutinative languages. Due to the productive morphology of agglutinative languages, the number of word forms encountered in naturally occurring text is very large. From the language modeling perspective, a large vocabulary results in serious data sparseness problems. In order to cope with this drawback, previous studies in various application areas suggest modified language models based on different morphological units. It is reported that performance improvements can be achieved with these modified language models. In our document categorization experiments, we use standard word form based language models as well as other modified language models based on root words, root words and part-of-speech information, truncated word forms and character sequences. Additionally, to find an optimum parameter set, multiple tests are carried out with different language model orders and smoothing methods. Similar to previous studies on other tasks, our experimental results on categorization of Turkish documents reveal that applying linguistic preprocessing steps for language modeling provides improvements over standard language models to some extent. However, it is also observed that similar level of performance improvements can also be acquired by simpler character level or truncated word form models which are language independent.

This study aims to answer the question, how much of Spanish Sign Language interpreting deaf individuals really understand. Study sampling included 36 deaf people (deafness ranging from severe to profound; variety depending on the age at which they learned sign language) and 36 hearing people who had good knowledge of sign language (most were interpreters). Sign language comprehension was assessed using passages of secondary level. After being exposed to the passages, the participants had to tell what they had understood about them, answer a set of related questions, and offer a title for the passage. Sign language comprehension by deaf participants was quite acceptable but not as good as that by hearing signers who, unlike deaf participants, were not only late learners of sign language as a second language but had also learned it through formal training.

Supply chain planning classification

Hvolby, Hans-Henrik; Trienekens, Jacques; Bonde, Hans

2001-10-01

Industry experience a need to shift in focus from internal production planning towards planning in the supply network. In this respect customer oriented thinking becomes almost a common good amongst companies in the supply network. An increase in the use of information technology is needed to enable companies to better tune their production planning with customers and suppliers. Information technology opportunities and supply chain planning systems facilitate companies to monitor and control their supplier network. In spite if these developments, most links in today's supply chains make individual plans, because the real demand information is not available throughout the chain. The current systems and processes of the supply chains are not designed to meet the requirements now placed upon them. For long term relationships with suppliers and customers, an integrated decision-making process is needed in order to obtain a satisfactory result for all parties. Especially when customized production and short lead-time is in focus. An effective value chain makes inventory available and visible among the value chain members, minimizes response time and optimizes total inventory value held throughout the chain. In this paper a supply chain planning classification grid is presented based current manufacturing classifications and supply chain planning initiatives.

2014-09-01

Full Text Available Second language acquisition cannot take place without having exposure to language input. With regard to this, the present research aimed at providing empirical evidence about the low and the upper-intermediate language learners’ preferred type of audiovisual programs and language proficiency development outside the classroom. To this end, 60 language learners (30 low level and 30 upper-intermediate level were asked to have exposure to their preferred types of audiovisual program(s outside the classroom and keep a diary of the amount and the type of exposure. The obtained data indicated that the low-level participants preferred cartoons and the upper-intermediate participants preferred news more. To find out which language proficiency level could improve its language proficiency significantly, a post-test was administered. The results indicated that only the upper-intermediate language learners gained significant improvement. Based on the findings, the quality of the language input should be given priority over the amount of exposure.

Word-length algorithm for language identification of under-resourced languages

Directory of Open Access Journals (Sweden)

Ali Selamat

2016-10-01

Full Text Available Language identification is widely used in machine learning, text mining, information retrieval, and speech processing. Available techniques for solving the problem of language identification do require large amount of training text that are not available for under-resourced languages which form the bulk of the World’s languages. The primary objective of this study is to propose a lexicon based algorithm which is able to perform language identification using minimal training data. Because language identification is often the first step in many natural language processing tasks, it is necessary to explore techniques that will perform language identification in the shortest possible time. Hence, the second objective of this research is to study the effect of the proposed algorithm on the run-time performance of language identification. Precision, recall, and F1 measures were used to determine the effectiveness of the proposed word length algorithm using datasets drawn from the Universal Declaration of Human Rights Act in 15 languages. The experimental results show good accuracy on language identification at the document level and at the sentence level based on the available dataset. The improved algorithm also showed significant improvement in run time performance compared with the spelling checker approach.

Language learning, language use and the evolution of linguistic variation

2017-01-01

Linguistic universals arise from the interaction between the processes of language learning and language use. A test case for the relationship between these factors is linguistic variation, which tends to be conditioned on linguistic or sociolinguistic criteria. How can we explain the scarcity of unpredictable variation in natural language, and to what extent is this property of language a straightforward reflection of biases in statistical learning? We review three strands of experimental work exploring these questions, and introduce a Bayesian model of the learning and transmission of linguistic variation along with a closely matched artificial language learning experiment with adult participants. Our results show that while the biases of language learners can potentially play a role in shaping linguistic systems, the relationship between biases of learners and the structure of languages is not straightforward. Weak biases can have strong effects on language structure as they accumulate over repeated transmission. But the opposite can also be true: strong biases can have weak or no effects. Furthermore, the use of language during interaction can reshape linguistic systems. Combining data and insights from studies of learning, transmission and use is therefore essential if we are to understand how biases in statistical learning interact with language transmission and language use to shape the structural properties of language. This article is part of the themed issue ‘New frontiers for statistical learning in the cognitive sciences’. PMID:27872370

Multilingualism can bring about various positive outcomes to typically developing children. Its effect on children with language difficulties is not yet clear. The aim of this study was to examine the effects of multilingual learning as a medium of instruction (MOI) on first language (L1) acquisition of children with language disorders (LD). Nineteen Cantonese-speaking students aged 5;8-6;8 who were diagnosed with LD were recruited from a school that used Putonghua (an alternative Chinese dialect) as the MOI when learning Chinese language and were compared with 18 age-and-gender-matched Cantonese-speaking students with LD from a school that used Cantonese as the MOI when learning Chinese language. All the students also learned English (L2) as a subject at school. Proficiency in Cantonese was tested at the beginning and the end of the semester in Grade One in terms of: (1) grammar, (2) expressive vocabulary, (3) auditory textual comprehension, (4) word definition and (5) narration. Mixed-model ANOVAs revealed an effect of time on language proficiency indicating positive gains in both groups. Interaction effects between time and group were not significant. There was a trend that children learning Putonghua showed slightly more improvement in auditory textual comprehension. Proficiency gains were similar across groups. The study found no evidence that a multilingual learning environment hinders the language proficiency in L1 in students who have LD. © 2011 Royal College of Speech and Language Therapists.

The objective of this paper is to conduct a preliminary assessment of the current radioactive contamination of soil, vegetation and foodstuffs in the two remaining villages closest to the Mayak site, Muslyumovo and Brodokalmak. Previous release of radioactivity from the Mayak Production Association plant in the South Urals have resulted in considerable radionuclide contamination of the Techa River, and consequent high radiation doses during the late 1940s and 1950s to residents of villages along the Techa river. The most contaminated villages close to the site were evacuated in the period 1954-1962. Nowadays the highest contamination levels in soil were found in the flood plain at 5.5 MBq m -2 for 1 37C s and 1.0 MBq m -2 for 9 0S r. The radionuclide contamination in soil of the two mentioned above villages was much lower, but exceeded that expected from global fallout. Data from 1207 measurements of 1 37C s in milk and 1180 for 9 0S r in milk for the period 1992-1999 were collated. There was no change with time in the 9 0S r or 1 37C s activity concentration in milk over the measured period. There were significantly higher 1 37C s activity concentrations in milk sampled during the stalled period in Muslyumovo compared with the grazing summer period, but no difference between that for Brodokalmak or for either settlement for 9 0S r. The highest measured activity concentrations in food products of 1 37C s and 9 0S r were found in river fish, waterfowl, poultry and milk. The measured activity concentration of 1 37C s and 9 0S r of some animal products were higher than that expected from that of soil and vegetation from fields and pasture in the villages (not including the flood plain) confirming that the highly contaminated flood plains are contributing to contamination of some animal products

Full Text Available The influence of industrial pollution on mortality values (dead fallen wood and dead standing trees and its distribution by degrees of decomposition were investigated in spruce-fir forest stands in the vicinity of the Middle Ural copper smelter (the city of Revda, Sverdlovsk region. The total mortality and mortality in each size category did not depend on the distance to the source of pollution. At the same time, the amount of dead fallen wood was significantly greater (1.9 times in the polluted area (2 and 4 km from the smelter as compared with the background territory (30 km from the smelter. Mortality proportion out of the total number of the trees (both live and dead did not differ significantly between the sites, although this parameter tended to increase nearer the smelter. The distribution of mortality by size categories revealed significant differences between background territory and site with average level of contamination, as well as background territory and highly contaminated site. Observed differences are associated with an increased proportion of lesser mortality near the smelter (by 15 % and 12 % as compared with areas of background and middle levels of contamination, respectively, as well as because of double-declining of medium- and large-sized mortality near the smelter. The distribution of the living tree stands by size categories also has a connection with level of contamination. The average diameters of the living tree stand and the elements of coarse woody debris (dead fallen wood and dead standing trees do not differ significantly between sites with different levels of contamination. For the small-sized dead fallen wood, the proportion of weakly decomposed stems increased with the level of pollution, while proportion of strongly decomposed stems decreased. The distribution of medium- and large-sized dead fallen wood on the stages of decomposition does not vary between sites with different levels of pollution.

Given a non-empty compact metric space X and a continuous function f: X → X, we study the dynamics of the induced maps on the hyperspace of non-empty compact subsets of X and on various other invariant subspaces thereof, in particular symmetric products. We show how some important dynamical properties transfer across induced systems. These amongst others include, chain transitivity, chain (weakly) mixing, chain recurrence, exactness by chains. From our main theorem we derive an ε-chain version of Furstenberg’s celebrated 2 implies n Theorem. We also show the implications our results have for dynamics on continua.

This hospital has performed fMRI of language-competent areas of the brain to identify the language-dominant hemisphere and obtain the configuration of the focus in the language-dominant side of the brain. Until now, signals have been detected in only two of fifteen patients who were diagnosed by language tests of a last-syllable word chain. In the present experiment, we tried to have subjects select the type of test. The result was that changes in signals were detected in eight of ten patients. Although the set-up of tests for fMRI is said to hold significant value, clear-cut studies to back this up have rarely been seen. Because clinical medicine treats patients who have difficulty in communication or suffer from aphasia, it is important to take into consideration individual variations and to set up a test suitable for, or achievable by, these individuals. The present method enabled us to avoid failure in examination caused by unsuccessful tests. (author)

ABSTRACT Purpose: Patients must be able to feel as much trust for caregivers and the healthcare system at the healthcare centre as at the emergency department. The aim of this study is to explain and understand the phenomenon of trust in the early chain of healthcare, when a patient has called an ambulance for a non-urgent condition and been referred to the healthcare centre. Method: A lifeworld hermeneutic approach from the perspective of caring science was used. Ten patients participated: seven female and three male. The setting is the early chain of healthcare in south-western Sweden. Results: The findings show that the phenomenon of trust does not automatically involve medical care. However, attention to the patient’s lifeworld in a professional caring relationship enables the patient to trust the caregiver and the healthcare environment. It is clear that the “voice of the lifeworld” enables the patient to feel trust. Conclusion: Trust in the early chain of healthcare entails caregivers’ ability to pay attention to both medical and existential issues in compliance with the patient’s information and questions. Thus, the patient must be invited to participate in assessments and decisions concerning his or her own healthcare, in a credible manner and using everyday language. PMID:28793852

Supply chains are at the heart of the way in which organisations operate and compete today; they also play a critical role in overall organisation performance. In the context of increasingly complex and global supply chains, the actions taken to drive down costs are likely to drive risk into the supply chain. The frequency of supply chain disruptions is high and this paper offers practical advice to help reduce the frequency and cost associated with these. There is advice to help with the understanding of how to identify critical suppliers. The reader is guided through comprehensive risk assessment and mitigation approaches and a selection of practical risk solutions and tools that you can use is described. There is a section on the 'dos and don'ts' relating to supplier due diligence. For those organisations facing the challenge of drawing up a business case relating to investment in improving supply chain resiliency, there is also a section outlining some of the business benefits of improving supply chain resiliency.

Based on the datasets obtained during investigations from 2003 to 2012, the spatial distributions of 90 Sr, 137 Cs, and 239,240 Pu content in the soils of the head part of the East Ural Radioactive Trace (EURT) were mapped using the geographic information system ArcGIS. Taking into account the presence of spatial autocorrelation and anisotropy in the source data, an ordinary kriging method was applied to interpolate values of radionuclide contamination density at unsampled places. Further geostatistical data analysis was performed to determine the basic parameters of spatial dependencies and to integrally assess the contamination by long-lived radionuclides in soils of the central, east peripheral, and west peripheral parts of the trace. This analysis was based on simplified geometric models (sector- and rectangle-shaped areas). The Monte Carlo method was used to quantitatively assess the uncertainty of the values for the integrated quantities resulting from the statistical errors of the source data approximation. - Highlights: • We investigated 102 soil samples in 2003–2012 at different distances from PA Mayak. • We mapped spatial distribution of 90 Sr, 137 Cs, and 239,240 Pu at this area by ArcGIS. • Integrated content based on sector- and rectangle-shaped models are similar. • The studied area clearly split into central, west, and east parts. • Radionuclide content of the central part is higher two orders than of west and east. - Capsule abstract: The spatial distribution of 90 Sr, 137 Cs, and 239,240 Pu at the EURT area by ArcGIS

IntroductionReturn the class to the students and let the students be the masters of the class.This is what I have changed during the last three years in my class.I have been using Communicative Language Teaching method instead of Grammar Translation method.In the Grammar Translation method, students only study grammar and learn lists of words and then translate what they have learned into Chinese.In the classroom,the teacher uses the students' first language to explain the grammar and vocabulary in the text and then helps the students to translate it.This method is based on the idea that language is made up of words and that language changes according to the grammar rules.

Simplexity, languages and human languaging

Cowley, Stephen; Gahrn-Andersen, Rasmus

2018-01-01

Building on a distributed perspective, the Special Issue develops Alain Berthoz's concept of simplexity. By so doing, neurophysiology is used to reach beyond observable and, specifically, 1st-order languaging. While simplexity clarifies how language uses perception/action, a community's ‘lexicon......’ (a linguistic 2nd order) also shapes human powers. People use global constraints to make and construe wordings and bring a social/individual duality to human living. Within a field of perception-action-language, the phenomenology of ‘words’ and ‘things’ drives people to sustain their own experience....... Simplex tricks used in building bodies co-function with action that grants humans access to en-natured culture where, together, they build human knowing....

The paper highlights the benefits obtained by the other partners if they comply with the best informed supply chain member in the development of the chain’s PMS, as well as how a PMS cannot be developed when none of the partners can be labelled as chain director.

Experience of Assessment of Current Radiation Doses to the Population from the Contamination of the Techa River (The Urals, Russia)

International Nuclear Information System (INIS)

2001-01-01

Full text: Significant quantities (about 108 PBq) of liquid radioactive waste were discharged to the Techa River in the Urals region of Russia in the early years of operation of the MAYK Production Association (1948-1951). The compositions of the releases consisted mainly of medium and long-lived beta emitting radionuclides: 103,106 Ru (28 PBq), 95 Zr/Nb (14 PBq), 137 Cs (13 PBq), 90 Sr (12 PBq). More than 120,000 people received high levels of radiation as a result of this contamination of the Techa River. The objective of this study is preliminary assessment of current and future radiation doses received by the population living in the affected area (Brodokalmak village). The assessment made use of local habit data and measurements of radionuclides concentrations in food and water, supplemented by model predictions whenever measurements in environmental materials were not available. Exposure pathways included in the calculations were ingestion of foods and external exposure to gamma radiation from radionuclides deposited on the banks of the river. Doses were calculated for three age groups (adults, children, infants) and two types of individuals: average consumers and users of the river banks, and individuals most likely to receive the highest dose. Two scenarios were considered in the calculations. In the first scenario is was assumed that access to the river banks, for both people and cattle, was restricted. For the second scenario, doses were calculated assuming that restrictions were lifted and people had free access to all areas in the village. With restrictions the highest dose estimated was 0.56 mSv/y for the most exposed adults and without restrictions this increased to 3.4 mSv/y. (author)

The extremes of a univariate Markov chain with regularly varying stationary marginal distribution and asymptotically linear behavior are known to exhibit a multiplicative random walk structure called the tail chain. In this paper we extend this fact to Markov chains with multivariate regularly varying marginal distributions in Rd. We analyze both the forward and the backward tail process and show that they mutually determine each other through a kind of adjoint relation. In ...

Event-Driven Process Chains (EPC)

Science.gov (United States)

Mendling, Jan

This chapter provides a comprehensive overview of Event-driven Process Chains (EPCs) and introduces a novel definition of EPC semantics. EPCs became popular in the 1990s as a conceptual business process modeling language in the context of reference modeling. Reference modeling refers to the documentation of generic business operations in a model such as service processes in the telecommunications sector, for example. It is claimed that reference models can be reused and adapted as best-practice recommendations in individual companies (see [230, 168, 229, 131, 400, 401, 446, 127, 362, 126]). The roots of reference modeling can be traced back to the Kölner Integrationsmodell (KIM) [146, 147] that was developed in the 1960s and 1970s. In the 1990s, the Institute of Information Systems (IWi) in Saarbrücken worked on a project with SAP to define a suitable business process modeling language to document the processes of the SAP R/3 enterprise resource planning system. There were two results from this joint effort: the definition of EPCs [210] and the documentation of the SAP system in the SAP Reference Model (see [92, 211]). The extensive database of this reference model contains almost 10,000 sub-models: 604 of them non-trivial EPC business process models. The SAP Reference model had a huge impact with several researchers referring to it in their publications (see [473, 235, 127, 362, 281, 427, 415]) as well as motivating the creation of EPC reference models in further domains including computer integrated manufacturing [377, 379], logistics [229] or retail [52]. The wide-spread application of EPCs in business process modeling theory and practice is supported by their coverage in seminal text books for business process management and information systems in general (see [378, 380, 49, 384, 167, 240]). EPCs are frequently used in practice due to a high user acceptance [376] and extensive tool support. Some examples of tools that support EPCs are ARIS Toolset by IDS

Language Management Tools

DEFF Research Database (Denmark)

Sanden, Guro Refsum

This paper offers a review of existing literature on the topic of language management tools – the means by which language is managed – in multilingual organisations. By drawing on a combination of sociolinguistics and international business and management studies, a new taxonomy of language...... management tools is proposed, differentiating between three categories of tools. Firstly, corporate policies are the deliberate control of issues pertaining to language and communication developed at the managerial level of a firm. Secondly, corporate measures are the planned activities the firm’s leadership...... may deploy in order to address the language needs of the organisation. Finally, front-line practices refer to the use of informal, emergent language management tools available to staff members. The language management tools taxonomy provides a framework for operationalising the management of language...

LANGUAGE, CULTURE AND IDENTITY: THE PORTUGUESE LANGUAGE AS A SYMBOLIC IDENTIFICATION SPACE ON DOCUMENTARY: LANGUAGE – LIVES IN PORTUGUESE

Directory of Open Access Journals (Sweden)

Joelton Duarte de Santana

2012-06-01

Full Text Available Language as a social element is constitutive to every human being. Language gives each person, as well as to his or her own linguistic community, an individual and peculiar way to figure out the world and its surroundings. Language is influenced by several processes, including sociocultural and historical ones. If we say that each language may allow its speaker to do a very own world reading, a question about its language behavior in other continents arises. This way we were able to understand how sociocultural influences could improve the whole cultural identity construction process. Both defining linguistic communities and specifying social groups, language becomes a symbolic space of identification. The movie – Language- lives In Portuguese reunites Portuguese speakers reports around the world aiming to illustrate Portuguese language as a nations identity construction, autoafirmation and legitimation factor through social, cultural and historic processes. This study is based on the belief in such a kind of dialogism between Language and Culture. The sociolinguistic studies nowadays do not intend, as they used to, understanding or describing structural language aspects and very individuals ones, but especially to reflect upon relations among subject, language, identity, culture and history.

Native language predictors of foreign language proficiency and foreign language aptitude.

Science.gov (United States)

Sparks, Richard L; Patton, Jon; Ganschow, Leonore; Humbach, Nancy; Javorsky, James

2006-06-01

Fifty-four students were tested at specific time intervals over 10 years to determine best native language (NL) predictors of oral and written foreign language (FL) proficiency and FL aptitude. All participants completed two years of Spanish, French, or German. Each was administered measures of NL literacy, oral language, and cognitive ability in elementary school. A measure of FL aptitude was administered at the beginning of ninth grade and FL proficiency was evaluated at the end of the 10th grade. Among the variables, NL literacy measures were the best predictors of FL proficiency, and NL achievement and general (verbal) intelligence were strong predictors of FL aptitude. Results suggest that indices of NL literacy as early as first grade are related to FL proficiency and FL aptitude nine and 10 years later. Findings provide strong support for connections between L1 and L2 skills, and for speculation that "lower level" skills in phonological processing are important for written language development and oral proficiency in a FL.

The benefits of sign language for deaf learners with language challenges

Directory of Open Access Journals (Sweden)

Van Staden, Annalene

2009-12-01

Full Text Available This article argues the importance of allowing deaf children to acquire sign language from an early age. It demonstrates firstly that the critical/sensitive period hypothesis for language acquisition can be applied to specific language aspects of spoken language as well as sign languages (i.e. phonology, grammatical processing and syntax. This makes early diagnosis and early intervention of crucial importance. Moreover, research findings presented in this article demonstrate the advantage that sign language offers in the early years of a deaf child’s life by comparing the language development milestones of deaf learners exposed to sign language from birth to those of late-signers, orally trained deaf learners and hearing learners exposed to spoken language. The controversy over the best medium of instruction for deaf learners is briefly discussed, with emphasis placed on the possible value of bilingual-bicultural programmes to facilitate the development of deaf learners’ literacy skills. Finally, this paper concludes with a discussion of the implications/recommendations of sign language teaching and Deaf education in South Africa.

Mesoscale simulation of semiflexible chains. I. Endpoint distribution and chain dynamics

Science.gov (United States)

Groot, Robert D.

2013-06-01

The endpoint distribution and dynamics of semiflexible fibers are studied by numerical simulation. A brief overview is given over the analytical theory of flexible and semiflexible polymers. In particular, a closed expression is given for the relaxation spectrum of wormlike chains, which determines polymer diffusion and rheology. Next a simulation model for wormlike chains with full hydrodynamic interaction is described, and relations for the bending and torsion modulus are given. Two methods are introduced to include torsion stiffness into the model. The model is validated by simulating single chains in a heat bath, and comparing the endpoint distribution of the chains with established Monte Carlo results. It is concluded that torsion stiffness leads to a slightly shorter effective persistence length for a given bending stiffness. To further validate the simulation model, polymer diffusion is studied for fixed persistence length and varying polymer length N. The diffusion constant shows crossover from Rouse (D ∝ N-1) to reptation behaviour (D ∝ N-2). The terminal relaxation time obtained from the monomer displacement is consistent with the theory of wormlike chains. The probability for chain crossing has also been studied. This probability is so low that it does not influence the present results.

Immigration, language proficiency, and autobiographical memories: Lifespan distribution and second-language access.

Science.gov (United States)

Esposito, Alena G; Baker-Ward, Lynne

2016-08-01

This investigation examined two controversies in the autobiographical literature: how cross-language immigration affects the distribution of autobiographical memories across the lifespan and under what circumstances language-dependent recall is observed. Both Spanish/English bilingual immigrants and English monolingual non-immigrants participated in a cue word study, with the bilingual sample taking part in a within-subject language manipulation. The expected bump in the number of memories from early life was observed for non-immigrants but not immigrants, who reported more memories for events surrounding immigration. Aspects of the methodology addressed possible reasons for past discrepant findings. Language-dependent recall was influenced by second-language proficiency. Results were interpreted as evidence that bilinguals with high second-language proficiency, in contrast to those with lower second-language proficiency, access a single conceptual store through either language. The final multi-level model predicting language-dependent recall, including second-language proficiency, age of immigration, internal language, and cue word language, explained ¾ of the between-person variance and (1)/5 of the within-person variance. We arrive at two conclusions. First, major life transitions influence the distribution of memories. Second, concept representation across multiple languages follows a developmental model. In addition, the results underscore the importance of considering language experience in research involving memory reports.

Topological self-organization and prediction learning support both action and lexical chains in the brain.

Science.gov (United States)

Chersi, Fabian; Ferro, Marcello; Pezzulo, Giovanni; Pirrelli, Vito

2014-07-01

A growing body of evidence in cognitive psychology and neuroscience suggests a deep interconnection between sensory-motor and language systems in the brain. Based on recent neurophysiological findings on the anatomo-functional organization of the fronto-parietal network, we present a computational model showing that language processing may have reused or co-developed organizing principles, functionality, and learning mechanisms typical of premotor circuit. The proposed model combines principles of Hebbian topological self-organization and prediction learning. Trained on sequences of either motor or linguistic units, the network develops independent neuronal chains, formed by dedicated nodes encoding only context-specific stimuli. Moreover, neurons responding to the same stimulus or class of stimuli tend to cluster together to form topologically connected areas similar to those observed in the brain cortex. Simulations support a unitary explanatory framework reconciling neurophysiological motor data with established behavioral evidence on lexical acquisition, access, and recall.

Language shift, bilingualism and the future of Britain's Celtic languages.

Science.gov (United States)

Kandler, Anne; Unger, Roman; Steele, James

2010-12-12

'Language shift' is the process whereby members of a community in which more than one language is spoken abandon their original vernacular language in favour of another. The historical shifts to English by Celtic language speakers of Britain and Ireland are particularly well-studied examples for which good census data exist for the most recent 100-120 years in many areas where Celtic languages were once the prevailing vernaculars. We model the dynamics of language shift as a competition process in which the numbers of speakers of each language (both monolingual and bilingual) vary as a function both of internal recruitment (as the net outcome of birth, death, immigration and emigration rates of native speakers), and of gains and losses owing to language shift. We examine two models: a basic model in which bilingualism is simply the transitional state for households moving between alternative monolingual states, and a diglossia model in which there is an additional demand for the endangered language as the preferred medium of communication in some restricted sociolinguistic domain, superimposed on the basic shift dynamics. Fitting our models to census data, we successfully reproduce the demographic trajectories of both languages over the past century. We estimate the rates of recruitment of new Scottish Gaelic speakers that would be required each year (for instance, through school education) to counteract the 'natural wastage' as households with one or more Gaelic speakers fail to transmit the language to the next generation informally, for different rates of loss during informal intergenerational transmission.

Full Text Available The paper focuses on Slovene - English language contact and the potential language change resulting from it. Both the immigrant context (the U.S. and Canada and Slovenia, where direct and indirect language contact can be observed respectively, are examined from two perspectives: social on the one hand and linguistic on the other. In the case of Slovene Americans and Canadians the emphasis is on language maintenance and shift, and on the relationship between mother tongue preservation and ethnic awareness. The linguistic section examines different types of bilingual discourse (borrowing, code switching, showing how the Slovene inflectional system in particular is being increasingly generalized, simplified and reduced, and how Slovene word order is gradually beginning to resemble that of English. In the case of Slovenia we are witnessing an unprecedented surge in the influence of English on Slovene, especially in the media (both classic and electronic, advertising, science, and the language of the young. This influence will be discussed on a number of levels, such as lexical, syntactic and intercultural, and illustrated by relevant examples.

Language development has been characterised by significant individual stability from school entry. However, the extent to which trajectories of language growth vary in children with language disorder as a function of co-occurring developmental challenges is a question of theoretical import, with implications for service provision. SCALES employed a population-based survey design with sample weighting procedures to estimate growth in core language skills over the first three years of school. A stratified sample (n = 529) received comprehensive assessment of language, nonverbal IQ, and social, emotional and behavioural difficulties at 5-6 years of age and 95% of the sample (n = 499) were assessed again at ages 7-8. Language growth was measured using both raw and standard scores in children with typical development, children with language disorder of unknown origin, and children with language disorders associated with a known clinical condition and/or intellectual disability. Overall, language was stable at the individual level (estimated ICC = 0.95) over the first three years of school. Linear mixed effects models highlighted steady growth in language raw scores across all three groups, including those with multiple developmental challenges. There was little evidence, however, that children with language disorders were narrowing the gap with peers (z-scores). Adjusted models indicated that while nonverbal ability, socioeconomic status and social, emotional and behavioural deficits predicted initial language score (intercept), none predicted language growth (slope). These findings corroborate previous studies suggesting stable language trajectories after ages 5-6 years, but add considerably to previous work by demonstrating similar developmental patterns in children with additional nonverbal cognitive deficits, social, emotional, and behavioural challenges, social disadvantage or clinical diagnoses. © 2017 The Authors.

Alignment between chain quality management and chain governance in EU pork supply chains: a Transaction-Cost-Economics perspective.

Science.gov (United States)

Wever, Mark; Wognum, Nel; Trienekens, Jacques; Omta, Onno

2010-02-01

Although inter-firm coordination of quality management is increasingly important for meeting end-customer demand in agri-food chains, few researchers focus on the relation between inter-firm quality management systems (QMS) and inter-firm governance structures (GS). However, failure to align QMSs and GSs may lead to inefficiencies in quality management because of high transaction-costs. In addition, misalignment is likely to reduce the quality of end-customer products. This paper addresses this gap in research by empirically examining the relation between QMSs and GSs in pork meat supply chains. Transaction-Cost-Economic theory is used to develop propositions about the relation between three aspects of QMSs--ownership, vertical scope and scale of adoption--and the use of different types of GSs in pork meat supply chains. To validate the propositions, seven cases are examined from four different countries. The results show that the different aspects of QMSs largely relate to specific GSs used in chains in the manner predicted by the propositions. This supports the view that alignment between QMSs and GSs is important for the efficient coordination of quality management in (pork meat) supply chains.

Measuring language lateralisation with different language tasks: a systematic review

2017-10-01

Full Text Available Language lateralisation refers to the phenomenon in which one hemisphere (typically the left shows greater involvement in language functions than the other. Measurement of laterality is of interest both to researchers investigating the neural organisation of the language system and to clinicians needing to establish an individual’s hemispheric dominance for language prior to surgery, as in patients with intractable epilepsy. Recently, there has been increasing awareness of the possibility that different language processes may develop hemispheric lateralisation independently, and to varying degrees. However, it is not always clear whether differences in laterality across language tasks with fMRI are reflective of meaningful variation in hemispheric lateralisation, or simply of trivial methodological differences between paradigms. This systematic review aims to assess different language tasks in terms of the strength, reliability and robustness of the laterality measurements they yield with fMRI, to look at variability that is both dependent and independent of aspects of study design, such as the baseline task, region of interest, and modality of the stimuli. Recommendations are made that can be used to guide task design; however, this review predominantly highlights that the current high level of methodological variability in language paradigms prevents conclusions as to how different language functions may lateralise independently. We conclude with suggestions for future research using tasks that engage distinct aspects of language functioning, whilst being closely matched on non-linguistic aspects of task design (e.g., stimuli, task timings etc; such research could produce more reliable and conclusive insights into language lateralisation.

The triple-A supply chain.

Science.gov (United States)

Lee, Hau L

2004-10-01

Building a strong supply chain is essential for business success. But when it comes to improving their supply chains, few companies take the right approach. Many businesses work to make their chains faster or more cost-effective, assuming that those steps are the keys to competitive advantage. To the contrary: Supply chains that focus on speed and costs tend to deteriorate over time. The author has spent 15 years studying more than 60 companies to gain insight into this and other supply chain dilemmas. His conclusion: Only companies that build supply chains that are agile, adaptable, and aligned get ahead of their rivals. All three components are essential; without any one of them, supply chains break down. Great companies create supply chains that respond to abrupt changes in markets. Agility is critical because in most industries, both demand and supply fluctuate rapidly and widely. Supply chains typically cope by playing speed against costs, but agile ones respond both quickly and cost-efficiently. Great companies also adapt their supply networks when markets or strategies change. The best supply chains allow managers to identify structural shifts early by recording the latest data, filtering out noise, and tracking key patterns. Finally, great companies align the interests of the partners in their supply chains with their own. That's important because every firm is concerned solely with its own interests. If its goals are out of alignment with those of other partners in the supply chain, performance will suffer. When companies hear about the triple-A supply chain, they assume that building one will require increased technology and investment. But most firms already have the infrastructure in place to create one. A fresh attitude alone can go a long way toward making it happen.

Iconicity as a general property of language: evidence from spoken and signed languages

Directory of Open Access Journals (Sweden)

Pamela Perniss

2010-12-01

Full Text Available Current views about language are dominated by the idea of arbitrary connections between linguistic form and meaning. However, if we look beyond the more familiar Indo-European languages and also include both spoken and signed language modalities, we find that motivated, iconic form-meaning mappings are, in fact, pervasive in language. In this paper, we review the different types of iconic mappings that characterize languages in both modalities, including the predominantly visually iconic mappings in signed languages. Having shown that iconic mapping are present across languages, we then proceed to review evidence showing that language users (signers and speakers exploit iconicity in language processing and language acquisition. While not discounting the presence and importance of arbitrariness in language, we put forward the idea that iconicity need also be recognized as a general property of language, which may serve the function of reducing the gap between linguistic form and conceptual representation to allow the language system to hook up to motor and perceptual experience.

Full Text Available As South Africa strives to be a major force in global markets, it is essential that South African supply chains achieve and maintain a competitive advantage. One approach to achieving this is to ensure that South African supply chains maximise their levels of efficiency. Consequently, the efficiency levels of South Africa’s supply chains must be evaluated. The objective of this article is to propose a model that can assist South African industries in becoming internationally competitive by providing them with a tool for evaluating their levels of efficiency both as individual firms and as a component in an overall supply chain. The Composite Supply Chain Efficiency Model (CSCEM was developed to measure supply chain efficiency across supply chains using variables identified as problem areas experienced by South African supply chains. The CSCEM is tested in this article using the Sishen-Saldanda iron ore supply chain as a case study. The results indicate that all three links or nodes along the Sishen-Saldanha iron ore supply chain performed well. The average efficiency of the rail leg was 97.34%, while the average efficiency of the mine and the port were 97% and 95.44%, respectively. The results also show that the CSCEM can be used by South African firms to measure their levels of supply chain efficiency. This article concludes with the benefits of the CSCEM.

2017-11-01

Full Text Available Language learning belief and language learning strategies are two essential predictors that have significant effect toward students’ language proficiency. Learners’ belief is dealing with what comes from inside the learners in learning the language, such as foreign language aptitude; difficulty of language learning; nature of language learning; learning and communication strategies; and motivation. Meanwhile, language learning strategies are learners’ plan in achieving certain goals or mastering the target language. A preliminary research was conducted in order to find what strategy mostly used by the learners. It turned out that the strategy mostly used by them was metacognitive strategies. Thus, this study aims to investigate about the correlation between metacognitive strategies and certain belief’ variables in students’ language learning which are foreign language aptitude and motivation. Moreover, twenty postgraduate students of English education department participated in this study. This study used correlational research, in which the BALLI (Beliefs about Language Learning Inventory and SILL (Strategies Inventory for Language Learners questionnaires were adopted as the instruments in collecting the data. The findings of this study indicated that there is negative linear correlation between metacognitive strategy and foreign language aptitude (rXY = -0,049 while there is significant positive linear correlation between metacognitive and motivation (rXY =+0,79 in students’ language learning. Furthermore, this study also provide some recommendations, which is it is expected that there will be more researches use studies using different respondents with various contexts. Secondly, the further research will use both of quantitative and qualitative data relating to this issue in order to make a more accurate data.

Full Text Available SMS language is English language slang, used as a means of mobile phone text messaging. This practice may impact on the written language skills of learners at school. The main aim of this study was to determine the perspectives of Grade 8 and 9 English (as Home Language educators in Gauteng regarding the possible influence of SMS language on certain aspects of learners' written language skills. If an influence was perceived by the educators, their perceptions regarding the degree and nature of the influence were also explored. A quantitative research design, utilising a questionnaire, was employed. The sample of participants comprised 22 educators employed at independent secondaryschools within Gauteng, South Africa. The results indicated that the majority of educators viewed SMS language as having a negative influence on the written language skills of Grade 8 and 9 learners. The influence was perceived as occurring in the learners' spelling, punctuation, and sentence length. A further finding was that the majority of educators address the negative influences of SMS language when encountered in written tasks.

Radiation induced solid-state polymerization of long-chain acrylates containing fluorocarbon chain

1995-01-01

γ-Ray irradiation post-polymerizations of long-chain acrylates containing fluorocarbon chain, H(CF 2 ) 10 CH 2 OCOCH=CH 2 and H(CF 2 ) 8 CH 2 OCOCH=CH 2 , were investigated and also the structures and thermal properties of comb-like polymers obtained were studied. It was found that these monomers exhibited very high polymerizability at wide temperature ranges around the melting points. Because the fluorocarbon chains are less flexible and thicker than the hydrocarbon chains, it can be expected that the aggregation force among the monomer molecules is strong and the conformational freedom of functional group for polymerization is large. According to the DSC and the X-ray diffraction measurements of the comb-like polymers obtained, the fluorocarbon chains are aggregated in a mode of hexagonal packing in the lamellar crystals. This situation can be considered as an optimum condition for the γ-ray irradiation post-polymerization. (author)

DOS cones along atomic chains

International Nuclear Information System (INIS)

Kwapiński, Tomasz

2017-01-01

The electron transport properties of a linear atomic chain are studied theoretically within the tight-binding Hamiltonian and the Green’s function method. Variations of the local density of states (DOS) along the chain are investigated. They are crucial in scanning tunnelling experiments and give important insight into the electron transport mechanism and charge distribution inside chains. It is found that depending on the chain parity the local DOS at the Fermi level can form cone-like structures (DOS cones) along the chain. The general condition for the local DOS oscillations is obtained and the linear behaviour of the local density function is confirmed analytically. DOS cones are characterized by a linear decay towards the chain which is in contrast to the propagation properties of charge density waves, end states and Friedel oscillations in one-dimensional systems. We find that DOS cones can appear due to non-resonant electron transport, the spin–orbit scattering or for chains fabricated on a substrate with localized electrons. It is also shown that for imperfect chains (e.g. with a reduced coupling strength between two neighboring sites) a diamond-like structure of the local DOS along the chain appears. (paper)

Full Text Available Problem Statement: EFL learners are rarely given opportunities to interact with native speakers and “…to do something with a language”. In Turkish settings, language learners mostly complain that they do not have enough opportunities to interact with native speakers, and class hours are too limited to acquire a language and more importantly they are not taught expressions that help them express themselves in daily contexts.Purpose of Study: This study aimed at investigating EFL (English as a Foreign Language learners’ experiences in a Language Exchange Community, namely xLingo.Method: 16 students from a state university spent time on language exchange communities. The researcher met these students once a week to make sure that everything was going fine. The students used xLingo for almost six months. The researcher interviewed them through the five questions that were earlier developed and piloted by the researcher himself.Findings and Results: The findings mostly focused on four aspects namely language development, autonomy, culture and self-confidence. Conclusions and Recommendations: Given the challenges Turkish EFL learners have to face in the process of language learning, language exchange communities are believed to open up more possibilities for language learners to get more comprehensible input and to interact with more native speakers and more importantly to do something with a language. In order to make best use of these communities, it is a mandatory step that language teachers be introduced to the concept along with practical applications and that these communities should be integrated into language testing system.

Chain Dynamics in Magnetorheological Suspensions

Science.gov (United States)

Gast, A. P.; Furst, E. M.

1999-01-01

Magnetorheological (MR) suspensions are composed of colloidal particles which acquire dipole moments when subjected to an external magnetic field. At sufficient field strengths and concentrations, the dipolar particles rapidly aggregate to form long chains. Subsequent lateral cross-linking of the dipolar chains is responsible for a rapid liquid-to-solid-like rheological transition. The unique, magnetically-activated rheological properties of MR suspensions make them ideal for interfacing mechanical systems to electronic controls. Additionally, the ability to experimentally probe colloidal suspensions interacting through tunable anisotropic potentials is of fundamental interest. Our current experimental work has focused on understanding the fluctuations of dipolar chains. It has been proposed by Halsey and Toor (HT) that the strong Landau-Peierls thermal fluctuations of dipolar chains could be responsible for long-range attractions between chains. Such interactions will govern the long-time relaxation of MR suspensions. We have synthesized monodisperse neutrally buoyant MR suspensions by density matching stabilized ferrofluid emulsion droplets with D2O. This allows us to probe the dynamics of the dipolar chains using light scattering without gravitational, interfacial, and polydispersity effects to resolve the short-wavelength dynamics of the dipolar chains. We used diffusing wave spectroscopy to measure these dynamics. The particle displacements at short times that show an independence to the field strength, but at long times exhibit a constrained, sub-diffusive motion that slows as the dipole strength is increased. The experiments are in good qualitative agreement with Brownian dynamics simulations of dipolar chains. Although there have been several important and detailed studies of the structure and interactions in MR suspensions, there has not been conclusive evidence that supports or contradicts the HT model prediction that long-range interactions exist between

In principle, a child can seemingly easily acquire any given language. First language acquisition follows a certain pattern which to some extent is found to be language independent. Since time immemorial, it has been of interest why children are able to acquire language so easily. Different disciplinary and methodological orientations addressing this question can be identified. A selective literature search in PubMed and Scopus was carried out and relevant monographies were considered. Different, partially overlapping phases can be distinguished in language acquisition research: whereas in ancient times, deprivation experiments were carried out to discover the "original human language", the era of diary studies began in the mid-19th century. From the mid-1920s onwards, behaviouristic paradigms dominated this field of research; interests were focussed on the determination of normal, average language acquisition. The subsequent linguistic period was strongly influenced by the nativist view of Chomsky and the constructivist concepts of Piaget. Speech comprehension, the role of speech input and the relevance of genetic disposition became the centre of attention. The interactionist concept led to a revival of the convergence theory according to Stern. Each of these four major theories--behaviourism, cognitivism, interactionism and nativism--have given valuable and unique impulses, but no single theory is universally accepted to provide an explanation of all aspects of language acquisition. Moreover, it can be critically questioned whether clinicians consciously refer to one of these theories in daily routine work and whether therapies are then based on this concept. It remains to be seen whether or not new theories of grammar, such as the so-called construction grammar (CxG), will eventually change the general concept of language acquisition.

The present study examined the relationship between mathematics and language to better understand the nature of the deficit and the academic implications associated with specific language impairment (SLI) and academic implications for English language learners (ELLs). School-age children (N = 61; 20 SLI, 20 ELL, 21 native monolingual English [NE]) were assessed using a norm-referenced mathematics instrument and 3 experimental computer-based mathematics games that varied in language demands. Group means were compared with analyses of variance. The ELL group was less accurate than the NE group only when tasks were language heavy. In contrast, the group with SLI was less accurate than the groups with NE and ELLs on language-heavy tasks and some language-light tasks. Specifically, the group with SLI was less accurate on tasks that involved comparing numerical symbols and using visual working memory for patterns. However, there were no group differences between children with SLI and peers without SLI on language-light mathematics tasks that involved visual working memory for numerical symbols. Mathematical difficulties of children who are ELLs appear to be related to the language demands of mathematics tasks. In contrast, children with SLI appear to have difficulty with mathematics tasks because of linguistic as well as nonlinguistic processing constraints.

Chain-modified radioiodinated fatty acids

Otto, C.A.

1987-01-01

Several carbon chain manipulations have been studied in terms of their effects on myocardial activity levels and residence time. The manipulations examined included: chain length, chain branching, chain unsaturation, and carbon-iodine bond stabilization. It was found that chain length affects myocardial activity levels for both straight-chain alkyl acids and branched chain alkyl and aryl acids. Similar results have been reported for the straight-chain aryl acids. Generally, the longer chain lengths correlated with higher myocardial activity levels and longer residence times. This behavior is attributed to storage as triglycerides. Branched chain acids are designed to be anti-metabolites but only the aryl β-methyl acids possessed the expected time course of constant or very slowly decreasing activity levels. The alkyl β-methyl acids underwent rapid deiodination - a process apparently independent of β-oxidation. Inhibition of β-oxidation by incorporation of carbon-carbon double and triple bonds was studied. Deiodination of ω-iodo alkyl fatty acids prevented an assessment of suicide inhibition using an unsaturated alkynoic acid. Stabilization of the carbon-iodine bond by attachment of iodine to a vinylic or aryl carbon was studied. The low myocardial values and high blood values observed for an eleven carbon ω-iodo vinylic fatty acid were not encouraging but ω-iodo aryl fatty acids appear to avoid the problems of rapid deiodination.

The emergence of temporal language in Nicaraguan Sign Language.

Kocab, Annemarie; Senghas, Ann; Snedeker, Jesse

2016-11-01

Understanding what uniquely human properties account for the creation and transmission of language has been a central goal of cognitive science. Recently, the study of emerging sign languages, such as Nicaraguan Sign Language (NSL), has offered the opportunity to better understand how languages are created and the roles of the individual learner and the community of users. Here, we examined the emergence of two types of temporal language in NSL, comparing the linguistic devices for conveying temporal information among three sequential age cohorts of signers. Experiment 1 showed that while all three cohorts of signers could communicate about linearly ordered discrete events, only the second and third generations of signers successfully communicated information about events with more complex temporal structure. Experiment 2 showed that signers could discriminate between the types of temporal events in a nonverbal task. Finally, Experiment 3 investigated the ordinal use of numbers (e.g., first, second) in NSL signers, indicating that one strategy younger signers might have for accurately describing events in time might be to use ordinal numbers to mark each event. While the capacity for representing temporal concepts appears to be present in the human mind from the onset of language creation, the linguistic devices to convey temporality do not appear immediately. Evidently, temporal language emerges over generations of language transmission, as a product of individual minds interacting within a community of users. Copyright © 2016 Elsevier B.V.

Language is generally considered a defining feature of human beings, a key medium for interpersonal communication, a fundamental tool for human thinking and an important vehicle for culture transmission. For the anthropoids to evolve into human being, the emergence of linguistic system is a vital step. Then, how can language serve functions so complicated and so important? To answer this question, it is necessary to probe into a central topic in linguistics: the structure of language, which has been inevitably involved in various fields of linguistic research-the functions of languages, the evolution of languages, the typology of languages, etc.

This report contains the first results on the analysis of the moss species Hylocomium splendens and Pleurozium schreberi which were used to study heavy metal atmospheric deposition in the vicinity of Magnitogorsk, the center of the iron steel industry of Russia. Moss samples were collected along Bannoe Lake, located 30 km north-west of Magnitogorsk, and were analyzed by instrumental neutron activation analysis using epithernal neutrons (ENAA) at the IBR-2 pulsed fast reactor in Dubna, and by atomic absorption spectroscopy (AAS) at the Geological Institute of RAS, Moscow. Results for a total of 38 elements were obtained, including Pb, Cd, and Cu determined by AAS. The element concentrations in moss samples from this area were compared with those available for the so-called 'Black Triangle' (the territory bordering Poland, Czechia and Slovakia), obtained by the same moss biomonitoring technique. The level of the concentrations of Fe, Cr, and V in the vicinity of Magnitogorsk was found to be 2-2.5 times higher than that of the mean values determined for the 'Black Triangle'; the level of Ni and Cd is of the same order as in the most polluted area of Europe. The concentrations of Zn and Cu tend to be higher in the 'Black Triangle'. The level of As is about 3 times higher in the Urals, whereas concentration of Pb is higher in Europe by a factor of 5. It appeared that concentration of Sb in the examined area has the highest ever published for levels in mosses from atmospheric deposition. The scanning electron microscope adjacent to the XRF analyzer (SEM-XRF) was used to examine the surface of the moss samples. Photographs of identified iron spherulas along with other aerosol particles were made at magnification of 3,500 to 5,000 times. Information on fieldwork in the northern part of the Chelyabinsk region in July, 1998 is reported. (author)

The effects of multisensory structured language instruction on native language and foreign language aptitude skills of at-risk high school foreign language learners: A replication and follow-up study.

Science.gov (United States)

Sparks, R L; Ganschow, L

1993-12-01

According to research findings, most students who experience foreign language learning problems are thought to have overt or subtle native language learning difficulties, primarily with phonological processing. A recent study by the authors showed that when a multisensory structured language approach to teaching Spanish was used with a group of at-risk high school students, the group's pre- and posttest scores on native language phonological processing, verbal memory and vocabulary, and foreign language aptitude measures significantly improved. In this replication and follow-up study, the authors compared pre- and posttest scores of a second group of students (Cohort 2) who received MSL instruction in Spanish on native language and foreign language aptitude measures. They also followed students from the first study (Cohort 1) over a second year of foreign language instruction. Findings showed that the second cohort made significant gains on three native language phonological measures and a test of foreign language aptitude. Follow-up testing on the first cohort showed that the group maintained its initial gains on all native language and foreign language aptitude measures. Implications for the authors' Linguistic Coding Deficit Hypothesis are discussed and linked with current reading research, in particular the concepts of the assumption of specificity and modularity.

Parental and speech and language therapist (SLT) explanatory models may affect engagement with speech and language therapy, but there has been dearth of research in this area. This study investigated parents' and SLTs' views about language development, delay and intervention in pre-school children with language delay. The aims were to describe, explore and explain the thoughts, understandings, perceptions, beliefs, knowledge and feelings held by: a group of parents from East Manchester, UK, whose pre-school children had been referred with suspected language delay; and SLTs working in the same area, in relation to language development, language delay and language intervention. A total of 24 unstructured interviews were carried out: 15 with parents whose children had been referred for speech and language therapy and nine with SLTs who worked with pre-school children. The interviews were transcribed verbatim and coded using Atlas/ti. The data were analysed, subjected to respondent validation, and grounded theories and principled descriptions developed to explain and describe parents' and SLTs' beliefs and views. Parent and SLT data are presented separately. There are commonalities and differences between the parents and the SLTs. Both groups believe that language development and delay are influenced by both external and internal factors. Parents give more weight to the role of gender, imitation and personality and value television and videos, whereas the SLTs value the 'right environment' and listening skills and consider that health/disability and socio-economic factors are important. Parents see themselves as experts on their child and have varied ideas about the role of SLTs, which do not always accord with SLTs' views. The parents and SLTs differ in their views of the roles of imitation and play in intervention. Parents typically try strategies before seeing an SLT. These data suggest that parents' ideas vary and that, although parents and SLTs may share some

Language and Recursion

Science.gov (United States)

Lowenthal, Francis

2010-11-01

This paper examines whether the recursive structure imbedded in some exercises used in the Non Verbal Communication Device (NVCD) approach is actually the factor that enables this approach to favor language acquisition and reacquisition in the case of children with cerebral lesions. For that a definition of the principle of recursion as it is used by logicians is presented. The two opposing approaches to the problem of language development are explained. For many authors such as Chomsky [1] the faculty of language is innate. This is known as the Standard Theory; the other researchers in this field, e.g. Bates and Elman [2], claim that language is entirely constructed by the young child: they thus speak of Language Acquisition. It is also shown that in both cases, a version of the principle of recursion is relevant for human language. The NVCD approach is defined and the results obtained in the domain of language while using this approach are presented: young subjects using this approach acquire a richer language structure or re-acquire such a structure in the case of cerebral lesions. Finally it is shown that exercises used in this framework imply the manipulation of recursive structures leading to regular grammars. It is thus hypothesized that language development could be favored using recursive structures with the young child. It could also be the case that the NVCD like exercises used with children lead to the elaboration of a regular language, as defined by Chomsky [3], which could be sufficient for language development but would not require full recursion. This double claim could reconcile Chomsky's approach with psychological observations made by adherents of the Language Acquisition approach, if it is confirmed by researches combining the use of NVCDs, psychometric methods and the use of Neural Networks. This paper thus suggests that a research group oriented towards this problematic should be organized.

Fuzzy Languages

Science.gov (United States)

Rahonis, George

The theory of fuzzy recognizable languages over bounded distributive lattices is presented as a paradigm of recognizable formal power series. Due to the idempotency properties of bounded distributive lattices, the equality of fuzzy recognizable languages is decidable, the determinization of multi-valued automata is effective, and a pumping lemma exists. Fuzzy recognizable languages over finite and infinite words are expressively equivalent to sentences of the multi-valued monadic second-order logic. Fuzzy recognizability over bounded ℓ-monoids and residuated lattices is briefly reported. The chapter concludes with two applications of fuzzy recognizable languages to real world problems in medicine.

The importance of efficiency in the supply chain of perishable products, such as the blood products used in transfusion services, cannot be overstated. Many problems can occur, such as the outdating of products, inventory management issues, patient misidentification, and mistransfusion. The purpose of this article was to identify the benefits and barriers associated with radiofrequency identification (RFID) usage in improving the blood bank supply chain. The methodology for this study was a qualitative literature review following a systematic approach. The review was limited to sources published from 2000 to 2014 in the English language. Sixty-five sources were found, and 56 were used in this research study. According to the finding of the present study, there are numerous benefits and barriers to RFID utilization in blood bank supply chains. RFID technology offers several benefits with regard to blood bank product management, including decreased transfusion errors, reduction of product loss, and more efficient inventory management. Barriers to RFID implementation include the cost associated with system implementation and patient privacy issues. Implementation of an RFID system can be a significant investment. However, when observing the positive impact that such systems may have on transfusion safety and inventory management, the cost associated with RFID systems can easily be justified. RFID in blood bank inventory management is vital to ensuring efficient product inventory management and positive patient outcomes.

A BPMN solution for chaining OGC services to quality assure location-based crowdsourced data

Science.gov (United States)

Meek, Sam; Jackson, Mike; Leibovici, Didier G.

2016-02-01

The Open Geospatial Consortium (OGC) Web Processing Service (WPS) standard enables access to a centralized repository of processes and services from compliant clients. A crucial part of the standard includes the provision to chain disparate processes and services to form a reusable workflow. To date this has been realized by methods such as embedding XML requests, using Business Process Execution Language (BPEL) engines and other external orchestration engines. Although these allow the user to define tasks and data artifacts as web services, they are often considered inflexible and complicated, often due to vendor specific solutions and inaccessible documentation. This paper introduces a new method of flexible service chaining using the standard Business Process Markup Notation (BPMN). A prototype system has been developed upon an existing open source BPMN suite to illustrate the advantages of the approach. The motivation for the software design is qualification of crowdsourced data for use in policy-making. The software is tested as part of a project that seeks to qualify, assure, and add value to crowdsourced data in a biological monitoring use case.

The road to language learning is iconic: evidence from British Sign Language.

Science.gov (United States)

Thompson, Robin L; Vinson, David P; Woll, Bencie; Vigliocco, Gabriella

2012-12-01

An arbitrary link between linguistic form and meaning is generally considered a universal feature of language. However, iconic (i.e., nonarbitrary) mappings between properties of meaning and features of linguistic form are also widely present across languages, especially signed languages. Although recent research has shown a role for sign iconicity in language processing, research on the role of iconicity in sign-language development has been mixed. In this article, we present clear evidence that iconicity plays a role in sign-language acquisition for both the comprehension and production of signs. Signed languages were taken as a starting point because they tend to encode a higher degree of iconic form-meaning mappings in their lexicons than spoken languages do, but our findings are more broadly applicable: Specifically, we hypothesize that iconicity is fundamental to all languages (signed and spoken) and that it serves to bridge the gap between linguistic form and human experience.

This review discusses the principles of polymerase chain reaction (PCR) and its application as a diagnostic tool in periodontology. The relevant MEDLINE and PubMed indexed journals were searched manually and electronically by typing PCR, applications of PCR, PCR in periodontics, polymorphism studies in periodontitis, and molecular techniques in periodontology. The searches were limited to articles in English language and the articles describing PCR process and its relation to periodontology were collected and used to prepare a concise review. PCR has now become a standard diagnostic and research tool in periodontology. Various studies reveal that its sensitivity and specificity allow it as a rapid, efficient method of detecting, identifying, and quantifying organism. Different immune and inflammatory markers can be identified at the mRNA expression level, and also the determination of genetic polymorphisms, thus providing the deeper insight into the mechanisms underlying the periodontal disease.

On the other hand, their speakers risk to miss the EU CEAS protection and to become victims of traffickers and exploiters of the Human Being. The present paper aims to draw the attention to the impact of the new languages received in Europe and to indicate European resources already able to work with some of them. It is trying to list the new added languages within the EU languages coming via Balkan route 2015, in the Q 3, looking to the first 10 “providers states” of the new languages. It limits the research on the languages coming from Asia. The analysis compares them, in terms of the number, of languages’ family; of the previous speakers’ communities’ presence within the EU. It will draw the attention to the Rare Added Languages in Europe (RALE, and especially, to some languages (and dialect belong to the family ROM and DOM. The rarity of some of the new added languages represents real issues for the immigration officers.

Full Text Available Within the scope of my investigation on language use and language attitudes of People of German Descent from the USSR, I find almost regular different language contact phenomena, such as viel bliny habn=wir gbackt (engl.: 'we cooked lots of pancakes' (cf. Ries 2011. The aim of analysis is to examine both language use with regard to different forms of language contact and the language attitudes of the observed speakers. To be able to analyse both of these aspects and synthesize them, different types of data are required. The research is based on the following two data types: everyday conversations and interviews. In addition, the individual speakers' biography is a key part of the analysis, because it allows one to draw conclusions about language attitudes and use. This qualitative research is based on morpho-syntactic and interactional linguistic analysis of authentic spoken data. The data arise from a corpus compiled and edited by myself. My being a member of the examined group allowed me to build up an authentic corpus. The natural language use is analysed from the perspective of different language contact phenomena and potential functions of language alternations. One central issue is: How do speakers use the languages available to them, German and Russian? Structural characteristics such as code switching and discursive motives for these phenomena are discussed as results, together with the socio-cultural background of the individual speaker. Within the scope of this article I present exemplarily the data and results of one speaker.
