Distribution coefficients have been determined for 137 Cs, 85 Sr, 144 Ce, 99 Tc, 152 Eu, 238 Pu, 244 Cm, and 243 Am between argillite from the Eleana Formation on the Nevada Test Site (NTS) and several aqueous phases. Radionuclide concentrations in the range of 1 to 0.001 μCi/ml were used with contact times of 14, 28, and 56 days. Reaction mechanism, concentration effects, exchange capacity, equilibration times, and particle size effects were addressed in a more comprehensive study of the interaction of argillite with Cs in deionized water. The experimental parameters used in the distribution coefficient measurements were based in part on this work. The aqueous phases included a simulated groundwater with composition based on the analysis of a NTS groundwater, the same simulant and deionized water which were pre-equilibrated with powdered argillite, and a groundwater simulant with approximately the same qualitative composition of the NTS simulant, but with a higher ionic strength. A system to provide continuous pH control by CO 2 addition during equilibration of the argillite-solution mixtures was designed and assembled. Initial experiments were done with Cs and Eu and the effects of pH on their distribution coefficients are discussed

It was defined that with temperature increasing the extraction rate of Al_2O_3 and Fe_2O_3 increases. The dependence of extraction rate of Al_2O_3 and Fe_2O_3 on process duration at hydrochloric acid decomposition of argillite was studied. The activation energy of the process was defined.

Hydro-mechanical coupling and transport in Meuse/Haute-Marne argillite: experimental and multi-scale approaches

International Nuclear Information System (INIS)

Cariou, S.

2010-07-01

This thesis deals with the hydro-mechanical behaviour of argillite. Classical Biot theory is shown to be badly adapted to the case of argillite. An original state equation is then built by use of homogenization tools, and takes into account the microstructure of argillite as well as physical phenomena happening inside the material, like the swelling overpressure inside the clay particles or the capillary effects in the porous network. This state equation explains some experiments which were not by the classical Biot theory. It is then improved by integrating the experimental data that are the dependency of the elasticity tensor with the saturation degree and the existence of a porosity surrounding the inclusions. Combined with the monitoring of length variation under hydric loading, this relevant state equation permits one to determine the Biot tensor of argillite. Since this state equation is coupled with the hydric state of the material, one is interested in modelling the variation of the saturation degree during a drying process. Two transport models are studied and compared, then a model for the porous network is proposed in order to explain the unusual permeability measurements. (author)

Iodine transfer in the Tournemire argillite

2009-01-01

In the framework of an underground radioactive waste disposal, 129 I constitutes for the argillaceous media one of the most penalizing elements owing to its very long life and its very low affinity. The objective of this work is to characterize the iodide transfer through the Tournemire argillite (Aveyron, France), in order to study thoroughly the iodide diffusive behaviour through an argillaceous matrix. An experimental methodology, which was based on a multi experimental method approach (batch, radial diffusion and through diffusion experiments), was applied for three different tracers: iodide, bromide, HTO. In the first part of this work, we show that the comparison between the HTO diffusion parameters and the anionic species highlights the existence of an anionic exclusion phenomenon which restricts the access of the anionic species to an accessible porosity inferior to the total rock porosity. In the second part of this work, we demonstrate that our retention and diffusion experiments indicate the existence of a significant affinity between 125 I and the Tournemire argillite. The 125 I retention appears to be irreversible, or with a kinetically very slow desorption within the duration of our experiments. Moreover, this retention intensity seems to be dependent on different experimental parameters such as the initial concentration of iodide or the ionic strength of the synthetic pore-water solution.

Energy policy, environmental protection and economy form a triangle of tightly linked sectors, and any solution of some energy problem can be solved only in the light of all the above mentioned factors. There are several energy master plans for Estonia, the first of them dating back to the years of the Soviet Union and ending the list with the plan to cover the years up to 2000. By now the basic principles of the Estonian energy policy have been prepared and Estonian Energy Concept is being worked out. The main goal of Estonian energy policy is ensure an effective and environmentally benign energy supply for the country. It means safety in energy supply, effective production and supply together with sufficient environmental protection. Energy Council in the role of an advisory voluntary organization for inspection of the energy system and finding measures to improve its efficiency is established with parliament members included. The Estonian Energy Research Institute and the Oil--Shale Research Institute serve as a scientific advisory board for the government in energy policy. It's important to emphasise that privatisation is no panacea, solving all the problems, and therefore we are facing hard to move in the right direction, satisfying all the consumers of energy

Full Text Available The article describes logistics survey in Estonia carried out in 2007 as a part of the LogOnBaltic project. The level of logistics in Estonian manufacturing, trading and logistics companies is explored through logistics costs, performance indicators, outsourcing, ICT use and logistics self-estimation of the companies responded. Responses from 186 Estonian companies were gathered through a web-based survey (38% of manufacturing, 38% of trading and 24% of logistics sector. Logistics costs as the percentage of turnover make in average 13.8% in manufacturing and 13.3% in trading. Transportation and inventory carrying cost form around 70% of overall logistics costs. Considering the logistics indicators surveyed, Estonian companies show up with relatively low perfect order fulfillment rates, short customer order fulfillment cycles and effective management of cash flows. The most widely outsourced logistics function is international transportation followed by domestic transportation, freight forwarding and reverse logistics. By 2010, the outsourcing of IT systems in logistics followed by inventory management, warehousing and product customization is expected to increase more substantially. The awareness of logistics importance is still low among Estonian companies. Only 27–44% of those agree that logistics has a considerable impact on profitability, competitive advantage, top management or customer service level.

Document available in extended abstract form only. A specific experimental device has been designed to produce hydrogen at the metal-argillite interface by electrochemistry. The target is for one hand to reproduce the production of hydrogen occurring when a metal is corroded by the water contained in the porosity of the mud-stone. On the other hand, the transfer of the hydrogen through the mud-stone can be studied. The specific features of the experiment are the following: - Hydrogen is generated inside a cell by electrochemistry, at the interface between the argillite and a metallic surface; no gas injection is required; - Electrochemistry gives the possibility to control the hydrogen production rate; - Hydrogen generation implies water consumption: the water comes from the porosity of the bulk argillite, near the interface; - That one-dimensional experiment has been built around a cylindrical sample of bulk and undamaged argillite coming from the Callovian-Oxfordian formation. Inside the device a cylindrical sample of argillite is placed above a nickel plate. Around the argillite, a ring of compacted bentonite ensures a mechanical confinement. When saturated, the bentonite will apply a swelling pressure close to the total pressure encountered by the sample in the geological formation. The hydrogen is generated at the interface nickel-argillite. The nickel plate is one of the two electrodes required for electrochemistry. At the top face of bentonite, iron electrode is used to close the electrical circuit. The hydrogen produced at the bottom face of the mud-stone is expected to go across the argillite towards the top face. A porous plate connected with a sampling bottle allows the capture of hydrogen. The argillite sample has a diameter of 50 mm, and a height of 50 mm. It is obtained by over-coring a core sample, and by a careful machining leading to a perfect geometry and surface quality. The production rate of hydrogen can be calculated from the current intensity

Full Text Available The article examines the cultural situation following postmodernism in the first decade of the 21st century. To characterise this situation, the umbrella term “post-postmodernism” is used, as well as “neomodernism”, “altermodern”, “metamodernism”, “hypermodernity”, “performatism”, “critical realism” etc. All these approaches are, in a wider sense, united by their aim of opposing postmodernist cynicism and irony, and bringing back truth, simplicity and clarity. It has also been found that literature has returned or is returning to realism, and various cultural phenomena are emerging, which have been designated by the concept “new sincerity”.In descriptions of the current cultural situation, this trend seeking truth and simplicity is supported by approaches which emphasise the significance of technological developments during the last decade. A prominent figure here is Alan Kirby, who launched the term “digimodernism”, mainly linked with the adaptation and spread of Web 2.0 at the beginning of the 21st century: the blogosphere, Wikipedia, Twitter and Facebook.The article seeks answers to the question of whether we can talk about digimodernism in Estonian literature in the 2000s. In the 1990s Estonian writers were quite reluctant to undertake computer-technological experiments, and there are only a few examples of Estonian digital literature, whereas a change occurred in the 2000s. Many Estonian writers have had and still have their own blogs and surprisingly many have joined Facebook. The term “twitterature” is also familiar to Estonian writers. The article tackles the dominant topics in the blogs of Estonian writers and analyses their possible collective creative work on Facebook. A question is raised as to whether it is possible that the fragmentary narrative structure of blogs and Facebook has influenced mainstream literature.The article concludes that one essential change in Estonian literature in the

Modelling the influence of water content on the mechanical behaviour of Callovo-Oxfordian argillite

Document available in extended abstract form only. The clay formation provides the geological background to many industrial and engineering applications. Especially in recent years, these types of material have been largely studied because they can be considered as potential host geological barrier for the underground storage of high level radioactive wastes. In view of this, several underground laboratories have been constructed in different countries. For instance: the Meuse/Haute Marne underground research laboratory (France), excavated in Callovo-Oxfordian argillite; the Mont Terri underground rock laboratory (Switzerland), constructed in Opalinus clay; the HADES Underground Research Laboratory (Belgium), located in Boom clay; the AECL underground research laboratory (Canada), achieved in the Lac du Bonnet granite batholith. The research realised in the underground laboratories allows us to obtain extensive experimental measurements and helps us to get a good understanding of the generalised behaviour of theses clays when subjected to complex solicitations (thermal, hydraulic, mechanical and chemical). In the underground storage, the experimental investigation and numerical prediction show that coupled hydro-mechanical processes will occur in the geological barrier for a very long time due to excavation/ ventilation and subsequence backfilling/sealing. In the excavation and exploitation stage, the unloading of host rock creates an EDZ zone and induces an increase local of permeability by several orders of magnitude around the galleries. Moreover, additional damage may be induced by the desaturation/re-saturation processes during ventilation/backfilling phase. On the other hand, the behaviour of clay formation is affected also by the presence of water and the pore pressure evolution. It is necessary to achieve a good understanding of the coupled hydro-mechanical behaviour to of clay formation for the designer of an underground storage. This paper focus on the

2009-11-01

Full Text Available The study was focussed on the relationships between ethnic self-esteem and various indicators of intergroup attitudes in a representative sample of adult population of Estonia (N=1142. Attitudinal variables that discriminated most between persons with high and low ethnic self-esteem were identified. Among Estonians ethnic self-esteem was related to positive ingroup bias, readiness for outgroup contact, perceived threat from the outgroup, attitudes to non-Estonian minority, and attitudes toward minority integration. Among non-Estonians ethnic self-esteem was related to readiness for outgroup contact, ethnic sterotypes, and various attitudes towards minority integration. An attempt was made to reconstruct the system of intergroup attidues of prototypical persons with high and low ethnic selfesteem and to describe psychological implications of high and low ethnic self-esteem for members of majority and minority groups. Various theoretical models (social identity theory, integrated threat theory, social dominane theory were used for interpretation of the results.

This work has for objective to evaluate the influence argillite and grog addition, obtained from defective bricks fired al low temperatures, into a clayey body for production of ceramic paver. Cylindrical specimens were uniaxial mold-press and then fired at 850 deg C in a laboratory furnace. The evaluated properties were: water absorption, diametral shrinkage and uniaxial compressive strength. The microstructure of the fired ceramics was evaluated electron scanning microscopy. The results showed that the argillite significantly decreased the water absorption and the shrinkage of the clayey body. The grog also decreased the shrinkage, but also decreased the mechanical strength. With respect to the water absorption, the grog not change this property of the composition elaborated with clays and argillite. (author)

The Tournemire experimental platform of IRSN in Aveyron is based on a tunnel and several galleries. The tunnel was excavated between 1882 and 1886 through Domerian marls and Toarcian argillites. Its walls were recovered by lime that is yet in contact with the argillites. The program associated to the study of the engineered analogues provided by the Tournemire experimental platform is presented in another paper. In parallel, lab experiments (diffusion and advection) are performed in smaller time (1 year) and space scale to control some parameters and complete engineered analogues results. This paper details the scientific program developed on these diffusion and advection lab samples. The diffusion study was designed to provide better understanding of the phenomena that govern diffusion processes during the transient phase between site and alkaline conditions. The advection study was designed to evaluate the influence of an advective hydraulic regime on the interaction argillite/alkaline fluid in comparison with the diffusive one. In all experiments, pH and concentrations (cations, anions) were monitored in time. Mineralogical and petrographic analyses (XRD, SEM, TEM) of the argillite cores were performed before and after the experiments for characterizing the mineral alterations and their potential role on the alkaline plume migration

2010-01-01

Document available in extended abstract form only. In the French concept of deep nuclear wastes repository, the galleries should be backfilled with excavated argillite after the site exploitation period. After several thousands of years, the degradation of the concrete lining of the galleries will generate alkaline fluid (pH > 12) that will diffuse through the backfill. The object of the study is to describe the influence of such solute diffusion on the microstructure of compacted argillite. Saturated-portlandite water was circulated through compacted samples for 3, 6 and 12 months at 20 or 60 deg. C. First, the mechanical behaviour of the samples was determined after the fluid circulation period. The microstructure of the samples was also analysed via mercury intrusion porosimetry tests, scanning electron microscopy and optical microscopy. Since it is planned to introduce additives (bentonite, calcareous sand or lime) in the remoulded argillite to backfill the deep galleries, such mixtures were also studied. The results showed that MA particles are sensitive to the alkaline fluid circulation at the microstructural level. In the case of the calcareous sand, no major changes of the microstructure nor the mechanical behaviour were observed. The pure argillite underwent slight modifications that can be related to a limited dissolution of its clayey particles. Conversely, intense alteration of the MX-80 particles was evidenced with a strong increase of the macro-pore void ration while the mechanical behaviour was slightly altered by the fluid circulation. Lime addition improved the mechanical characteristics of the argillite through the precipitation of cementitious compounds. The microstructure of the lime-treated argillite was also altered by the fluid circulation. That study evidenced that alkaline fluid circulation led to the dissolution clayey particles, leading to the increase of the macro-pore void ratio. Some of the dissolved compounds allowed the formation of

The Organization of Estonian energetic economy is aimed at cutting the usage of oil, gas and coal and increasing the local resources firewood, oil-shale and peat for fuel. The resources of low-valued firewood-brushwood, fallen deadwood etc. are available during the following 10-15 years, but in the future the cultivation of energy forest (willow) plantations will be actual. During the last 20 years the Swedish scientists have been extensively studying the willow forest selection, cultivation and use in energetics and waste water purification systems. A Swedish-Estonian energy forest research project was started in 1993 between the Swedish Agricultural University on one hand and Toravere Observatory, Institute of Zoology and Botany, Estonian Academy of Sciences and Estonian Potato Processing Association on the other hand. In spring 5 willow plantations were established with the help of Swedish colleagues and obtained from Sweden 36000 willow cuttings. The aim of the project: a) To study experimentally and by means of mathematical modelling the biogeophysical aspects of growth and productivity of willow plantations in Sweden and Estonian climatological conditions. b) To study the possibility of using the willow plantations in waste waters purification. c) To study the economical efficiency of energy forest as an energy resource under the economic and environmental conditions of Estonia. d) To study the economic efficiency of willow plantations as a raw material for the basket industry in Estonia. e) To select the most productive and least vulnerable willow clones for practical application in energy plantations. During 1993 in all five plantations detailed analysis of soil properties has been carried out. In the plantation at Toravere Observatory phytometrical measurements were carried out - the growth of plant biomass leaf and stem area, vertical distribution of dry matter content, biomass and phyto area separately for leaves and stems has been performed.

Contributions to micromechanical model of the non linear behavior of the Callovo-Oxfordian argillite

International Nuclear Information System (INIS)

Abou-Chakra Guery, A.

2007-12-01

This work is performed in the general context of the project of underground disposal of radioactive waste, undertaken by the French National Radioactive Waste Management Agency (ANDRA). Due to its strong density and weak permeability, the formation of Callovo-Oxfordian argillite is chosen as one of possible geological barriers to radionuclides. The objective of the study to develop and validate a non linear homogenization approach of the mechanical behavior of Callovo-Oxfordian argillites. The material is modelled as a composite constituted of an elasto(visco)plastic clay matrix and of linear elastic or elastic damage inclusions. The macroscopic constitutive law is obtained by adapting the incremental method proposed by Hill. The derived model is first compared to Finite Element calculations on unit cell. It is then validated and applied for the prediction of the macroscopic stress-strain responses of the argillite at different geological depths. Finally, the micromechanical model is implemented in a commercial finite element code (Abaqus) for the simulation of a vertical shaft of the underground laboratory. This allows predicting the distribution of damage state and plastic strains and characterizing the excavation damage zone (EDZ). (author)

A study on the dynamic behavior of the Meuse/Haute-Marne argillite

Science.gov (United States)

Cai, M.; Kaiser, P. K.; Suorineni, F.; Su, K.

Excavation of underground tunnels can be conducted by tunnel boring machines (TBM) or drill-and-blast. TBMs cause minimum damage to excavation walls. Blasting effects on excavation walls depend on the care with which the blasting is executed. For blast-induced damage in excavation walls, two issues have to be addressed: rate of loss of confinement (rate of excavation) and dynamic loading from wave propagation that causes both intended and unintended damage. To address these two aspects, laboratory dynamic tests were conducted for the determination of the dynamic properties of the Meuse/Haute-Marne argillite. In the present study, 17 tensile (Brazilian) and 15 compression split Hopkinson pressure bar (SHPB) tests were conducted. The test revealed that the dynamic strengths of the argillite are strain rate dependent. The average dynamic increase factors (ratio of dynamic strength to static strength) for tensile and compressive strength are about 3.3 and 2.4, respectively. A high-speed video camera was used to visualize the initiation of failure and subsequent deformation of the specimens. The direct compression specimens were found to deform and fail uniformly around the circumference of the specimen, by a spalling process. The SHPB Brazilian tests indicated that failure occurred in tension along the line of load application. Radial fractures were also observed. The test results can be used for the development of a dynamic constitutive model for the argillite for the prediction of damage in underground excavation utilizing the drill-and blast method.

Microbial corrosion of steel in Toarcian argillite: potential influence of bio-films

Document available in extended abstract form only. In the context of a geological disposal of radioactive waste in clayey formations, the consequences of microbial activity are of concern regarding the corrosion of metallic components, such as the overpack surrounding vitrified waste. Generalized corrosion is one of the main processes taken into account in the dimensioning of these overpacks. However, the presence of microorganisms such as sulfate- or thiosulfate-reducing bacteria in the host rock in contact with these non-alloy materials may enhance localized corrosion processes, leading to a premature and undesirable loss of watertightness. Moreover, the passive corrosion layer, which is formed progressively during the generalized corrosion process and induces a decrease of corrosion rates, may react with iron-reducing bacteria and thus reactivate corrosion. The formation of bio-films may also lead to significant modifications of environment at the biofilm/metal interface in terms of pH, dissolved oxygen, organic and inorganic species, that may lead to electrochemical reactions that could potentially increase corrosion rates. There is thus a need for further investigations of the potential consequences on the physico-chemical conditions within geological disposal facilities. The French Institute for Radiological Protection and Nuclear Safety (IRSN) has been conducting research programs since 1991 in the Tournemire Underground Research Laboratory (URL), a railway tunnel which crosses a Toarcian argillaceous formation. This geological layer is particularly interesting for its physical and chemical properties close to those of Callovo-Oxfordian argillite. The importance of microbial processes in this formation was first shown by the study of time evolution of the chemical and isotopic compositions of fracture groundwaters collected in several boreholes. These investigations suggested that aqueous sulphates and their isotopic composition were controlled by bacterial

Using the transient method, we determine the permeability of high-quartz Eleana argillite from the Nevada Test Site as a function of effective pressure. By comparing calculated and observed pressure decay in the upstream reservoir, we have determined the permeability of intact and fractured specimens at effective pressures ranging from 1.0 to 24.0 MPa. Over this pressure range, Eleana argillite has a low permeability (10 -16 to 10 -19 cm 2 ) when intact and a higher permeability (10 -12 to 10 -17 cm 2 ) with one induced through-going fracture

A middle Jurassic shale, the Callovo-Oxfordian argillite (420-560 m b.g.), is currently being intensively investigated at the ANDRA site, about 300 km eastern from Paris, and particularly with respect to its hydrogeological and hydrochemical properties. The argillite rests between the Oxfordian Limestone above and the Dogger Limestone below. Observations from the different deep boreholes located at the site can be summarized as follows: the measured apparent hydraulic head across the Callovo-Oxfordian argillite show excess values of several tens of meters in comparison to the upper and lower aquifers, a fact which is referred to as anomalous overpressure in the shale literature; the salinity of the pore water in the Callovo-Oxfordian argillite and the Dogger is much larger than that of the Oxfordian. The salinity levels in the Callovo-Oxfordian and the Dogger are similar. Among all physical processes which can be proposed as explanation for the formation of overpressure in shales, osmosis driven by a chemical potential (total dissolved solids) gradient is a possible candidate. As a matter of fact, the presence of contrasts in water composition and clay minerals content, as observed here, lead to osmotic effects. This paper presents the results of simulations using steady-state approximations and transient simulations (software OSMO, a numerical simulator developed by the British Geological Survey). It is shown that based on the extensive database of argillite measurements applicable to the study (including porosity values, specific surface determinations, pore water compositions, and effective diffusion coefficients), the chemo-osmosis is a process which can at least explain partly the anomalous overpressures observed.

Estonian horticultural peat marketing: sales promotion and price formation. 2. part

International Nuclear Information System (INIS)

Hammer, Hele

1999-01-01

When forming prices, Estonian peat companies' decisions should be based on marginal cost analysis. Unfortunately most Estonian companies sell peat to intermediaries and cannot influence its price. Estonian peat producers have to choose between either selling peat directly or selling through a central marketing organization. Both systems have their pros and cons. Direct selling gives more freedom to individual producers but is more risky. Central marketing makes cost saving possible and is more effective and stable, but may alienate producers from clients and markets. Whichever marketing system Estonian peat companies choose, the most important elements in their marketing strategy should be: careful market analysis, personal sales, attending trade shows, catalogues, quality service and offering transportation services.

Sealing efficiency of an argillite-bentonite plug subjected to gas pressure, in the context of deep underground nuclear waste storage

International Nuclear Information System (INIS)

Liu, Jiang-Feng

2013-01-01

In France, the deep underground nuclear waste repository consists of a natural barrier (in an argillaceous rock named argillite), associated to artificial barriers, including plugs of swelling clay (bentonite)-sand for tunnel sealing purposes. The main objective of this thesis is to assess the sealing efficiency of the bentonite-sand plug in contact with argillite, in presence of both water and gas pressures. To assess the sealing ability of partially water-saturated bentonite/sand plugs, their gas permeability is measured under varying confining pressure (up to 12 MPa). It is observed that tightness to gas is achieved under confinement greater than 9 MPa for saturation levels of at least 86-91%. We than assess the sealing efficiency of the bentonite-sand plug placed in a tube of argillite or of Plexiglas-aluminium (with a smooth or a rough interface). The presence of pressurized gas affects the effective swelling pressure at values P gas from 4 MPa. Continuous gas breakthrough of fully water-saturated bentonite-sand plugs is obtained for gas pressures on the order of full swelling pressure (7-8 MPa), whenever the plug is applied along a smooth interface. Whenever a rough interface is used in contact with the bentonite-sand plug, a gas pressure significantly greater than its swelling pressure is needed for gas to pass continuously. Gas breakthrough tests show that the interface between plug/argillite or the argillite itself are two preferential pathways for gas migration, when the assembly is fully saturated. (author)

Full Text Available Purpose – The study is a contribution to the validation of the 15 items and 5 subscales Transformational Leadership Scale (TLS proposed by Rafferty and Griffin (2004. Design/methodology/approach – The sample includes participants from different levels of the Estonian Defence Forces (EDF military hierarchy (N=2570. The structure of the TLS was examined by using exploratory and confirmatory factor analyses. Additionally ANOVA was used to compare the results between different subsamples. Findings – TLS showed satisfactory reliability. Confirmatory factor analyses found TLS as valid five dimensions instrument to measure transformational leadership in the Estonian military context. Different management levels showed different emphases among the dimensions of transformational leadership. Research and practical limitations/implications – TLS will be an important tool to use in transformational leadership research in the Estonian military context and beyond. Additionally, the current research contributes to the development of alternative measurement tools besides the most commonly used MLQ. The limitation of the work will be the rather homogenous sample from the Estonian military, however it will open the door for the subsequent research using different samplings. Originality/value – The current research found TLS to be a reliable and valid instrument, very short and therefore easy to administrate, having the possibility to use it with five dimensional and as one general transformational instrument as well.

Uniting the Divided Continent. The Estonian National Committee of the European Movement

Pauli Heikkilä

2010-12-01

Full Text Available The article examines the exiled Estonian politicians in the European Movement in the early Cold War period. The ultimate goal of exiled Estonians was to restore their state’s independence. In order to promote this, Estonian leaders sought connections with Western leaders. The European Movement was the only organisation involving actors from both the East and the West, and this corresponded to the Estonian discourse on Europe as a whole. Therefore, the European Movement was appreciated, although its limited opportunities for decisive actions were also recognised. East and West European interest in the European Movement declined as West European integration rapidly intensified through the European Coal and Steel Community (ECSC and particularly after the January 1952 Eastern European Conference in London. By 1957, disappointment in the inability of European unification to help regain Estonian independence became evident.

On the System of Place Name Signs in Estonian Sign Language

Directory of Open Access Journals (Sweden)

Liina Paales

2011-05-01

Full Text Available A place name sign is a linguistic-cultural marker that includes both memory and landscape. The author regards toponymic signs in Estonian Sign Language as representations of images held by the Estonian Deaf community: they reflect the geographical place, the period, the relationships of the Deaf community with hearing community, and the common and distinguishing features of the two cultures perceived by community's members. Name signs represent an element of signlore, which includes various types of creative linguistic play. There are stories hidden behind the place name signs that reveal the etymological origin of place name signs and reflect the community's memory. The purpose of this article is twofold. Firstly, it aims to introduce Estonian place name signs as Deaf signlore forms, analyse their structure and specify the main formation methods. Secondly, it interprets place-denoting signs in the light of understanding the foundations of Estonian Sign Language, Estonian Deaf education and education history, the traditions of local Deaf communities, and also of the cultural and local traditions of the dominant hearing communities. Both perspectives - linguistic and folkloristic - are represented in the current article.

Flue gas emissions from pulverized oil shale fired boilers of Estonian and Baltic power plants have been studied. The concentrations of NO x , CO, C x H y , HCI, Hf and polycyclic aromatic hydrocarbons in flue gases have been found to be relatively low and acceptable according to German emission limits, for instance. Desulphurization degree of flue gases by SO 2 absorption with ash has been found to vary defending on boiler type and operation conditions. In spite of significant sulphur capture (average values for different boilers in the range between 68 and 77 % of the initial sulphur content of the fuel), SO 2 concentrations in flue gases remain still very high (up to 2600 mg/m 3 , 10% O 2 ). Very high concentrations of particles, especially at Estonian Power Plant (up o 6250 mg/m 3 , 10 % 0 2 ) have been detected. Heavy metal emissions were too high by the reason of particle control insufficiency as well. Yearly emission estimates of this study support the former Estonian ones within the range of 10-15 %.

Modelling of the mechanical behaviour and damage of clay-stones: application to the East argillite

International Nuclear Information System (INIS)

Aublive-Conil, N.

2003-03-01

The storage in deep geological formation is one of the solutions retained by France for the management of highly long life radioactive waste. The retained host rock is a clay-stone named East argillite located in the departments of Meuse and Haute-Marne. A thermodynamic formulation is used to propose a rheological model, which reproduces the mechanical behavior of clay-stones. Initially, an anisotropic damage plastic model was formulated in order to describe material degradations. Then, the damage plastic model is reformulated in order to taken into account the damage influence on the hydraulic behavior of porous material. The numerical simulations correctly reproduce the mechanical behavior of East Argillites but also the anisotropy of the hydraulic behavior introduced by the damage effect. (author)

Document available in extended abstract form only. The fundamental features of the Callovo Oxfordian argillite, namely the structure and the pore size distribution are considered to propose a model consistent with its mechanical behavior. The model deals with the main mechanisms selected: damage, plasticity and swelling. Structure of Argillites as fundamental base of mechanical behavior Callovian-Oxfordian argillites present specific characteristics: - a strong mineralogical heterogeneity made up from 23% to 25% of quartz, 20% to 27% of carbonate, 40% to 50% of argillaceous minerals and 5% to 10% various mineral; - a low porosity comprised between 12 to 15%, associated with the following pore size distribution: 14% of nano-pores, majority 81% of meso-pores and 5% of macro-pores; - a low Biot coefficient, around 0.6; - no cementing (within the meaning of a concrete). Four basic mechanisms are considered likely to explain the structure of argillite in place: - mechanical consolidation obtained by increasing external stress, - chemical consolidation by reduction in dielectric constant (leaching of chlorides), - thermal consolidation, - filling of the macro-porosity by precipitation of a carbonated phase (calcite). Experimental tests were performed to evaluate the weight of these mechanisms. Results show that mechanic and thermal consolidations, in the fields of stress and temperature encountered in situ by argillite during geological history, and chemical consolidation could not alone explain the state the high density without macro porosity. An assumption advanced to explain is the filling of macro porosity by non argillaceous mineral precipitation, in particular calcite that would confer to in situ argillite an apparent over-consolidation from a mechanical point of view. This assumption is partially validated by some experiments: - Percolation tests were made with hydrochloric acid on bulky and sound argillite to remove the carbonates in the macro-porosity; they

Dissolved chloride in argillite pore water has been studied as a natural analogue for radionuclides potentially released from radioactive waste disposal. The Tournemire URL intersects impervious and compacted argillite. A previously obtained chloride concentration profile of intact rock is symmetric with a maximum concentration of 0.6±0.1 g/L, compared to 19 g/L for the original connate seawater. Dissolved chloride shows high δ 37 Cl values, ranging between +6 and +80/00 vs. SMOC. The modeled profile considers diffusive exchange between connate seawater and meteoric freshwater. Transport parameters were obtained by radial diffusion experiments. Numerical modeling was performed with the coupled reactive-transport code Hytec. Simulations suggest a diffusive-exchange time of 85±10 Ma for Cl, which correlates with a major erosional period. Simulated δ 37 Cl values between 1.002 and 1.003 agree with observed pore water δ 37 Cl. This study strongly suggests that the dissolved chloride profile in the argillites results from diffusive exchange and indicates that unfractured argillites can provide good confinement. (authors)

Estonian Language of Technology as a Factor Supporting the Evolution of Engineering Thinking

Directory of Open Access Journals (Sweden)

Mägi, Vahur

2013-03-01

Full Text Available Casual mention of teaching technology subjects in Estonian schools dates back several centuries. Navigation and construction were amongthe earliest professional skills that were taught. As both of them required mathematical thinking skills, teaching the subjects was usually accompanied by explaining the principles of mathematics. The first technology book in Estonian was published about two centuries ago and it dealed with geodesy. The earliest Estonian glossaries of technological terminology were published in the fields of physics and chemistry. The rise of Estonian as a language of higher education and science in the country came about in the 1920s and 1930s. Faculty members of the Tallinn School of Technology then published the first textbooks composed in the Estonian language for students of technology. The Estonian Society for Technology and the Estonian Association of Engineers became seriously involved in linguistic activities. Together with the Vocational Teachers’ Assembly of Tartu they published an illustrated technology glossary for machinery and tools terms. It was followed by a glossary of construction and building terms, compiled under the lead of the University of Technology. In addition, journals of technology introducedinnovations in the lexicon of technology to the general public. The postwar period in the development of the lexicon of technical terms was of little significance at first. A surge in language creativity could be detected in the 1960s, when terminology became a target of constantly growing attention to the development of technology lexicon. Series of technology glossaries were published. This tendency has continued to this day.

Argillite / cementitious materials interaction: in-situ investigations and modeling of engineered analogues from the Tournemire experimental station

International Nuclear Information System (INIS)

Techer, I.; Bartier, D.; Dauzeres, A.; Boulvais, P.

2012-01-01

Document available in extended abstract form only. Deep geological disposal of high-activity and long-period radioactive wastes is designed by the French National Agency for Radioactive Waste Management (Andra) with a confinement system based on the multiplication of argillaceous and cement-bearing barriers called 'engineered barriers'. The role of these barriers is to avoid the release of radioelements into the biosphere, as well as to prevent the potential addition of external fluids to the waste materials. In a deep clay-rich medium, cementitious materials will compose most of the building structures and will be emplaced at the immediate contact with the natural argillaceous formation. Cementitious materials are known to produce hyper-alkaline pore fluids (with pHs ranging between 10 and 13.5) during their aging. Their introduction in a deep clayey disposal is thus expected to induce a chemical disequilibrium which imprint on the safety assessment of the storage must be characterized. One way to evaluate the potential disturbing of a clayey formation at the contact to a cementitious material and thus towards the percolation of hyper-alkaline fluids consists with the investigation of natural analogues or engineered analogues. These systems deals with clayey formations that have been maintained over several years to hundred of years at the contact with a natural or engineered cementitious material. The Tournemire Experimental Platform of the French Institute for Radioprotection and Nuclear Safety (IRSN) (Aveyron, SE France) presents many contexts of so-defined engineered analogues. For instance, exploration boreholes that were drilled vertically from the tunnel basement into the Toarcian argillite in 1990/1991 were filled soon after their drilling with CEM II cement paste and concrete. Today, the over coring of such concreted boreholes gives opportunities to examine the cementitious and the clayey materials and to discuss potential changes of their intrinsic

Noor eesti teater ja Noor-Eesti. Young Estonian Theatre and Young Estonia

2012-04-01

Full Text Available This article begins by examining points of intersection between two professional theatres, ”Estonia” and ”Vanemuine” (both established in 1906, their young directors – Karl Menning, Paul Pinna, Theodor Altermann, and Karl Jungholz, and the literary movement Young Estonia. Subsequently, we will consider Young Estonia’s theatrical ideals and the influence of these ideas on later Estonian theatrical life. Since not much information has survived regarding direct personal contacts between ”movers and shakers” in the theatre world and Young Estonians, the main focus here shall be on indirect creative connections and influences. One such context is education: like the Young Estonians, theatre activists of the younger generation aspired to place themselves on the larger map of European culture. Thus, their artistic beliefs and goals shall be examined in relation to those of Young Estonians’ quest for modern culture. Pinna, Altermann, Menning, Jungholz, and others went on study tours to Germany and France, where they were energized and inspired by innovative German and Russian theatres, by naturalistic staging, and by psychological realism, both in acting and in performance style. Among their models were A. Antoine’s Théâtre- Libre in Paris, K. Stanislavski’s Art Theatre in Moscow, O. Brahm’s Lessing-Theater, and M. Reinhardt’s Deutsches Theater in Berlin. These models were likewise known to the Young Estonians, but if theatre activists oriented themselves more fundamentally to German naturalist and realist dramatic art, Young Estonians were more taken with ”theatrical theatre” with its symbolist and impressionist influences. The Young Estonians attended performances at both theatres, ”Vanemuine” and ”Estonia”, and wrote numerous theatre reviews. Yet in the Young Estonia albums (yearbooks and in the magazine Young Estonia, theatre topics have a relatively modest representation. Young Estonians did not have direct

The intention of this document is to provide a path-forward for research and development (R&D) for two host rock media-specific (argillite and crystalline) disposal research work packages within the Used Fuel Disposition Campaign (UFDC). The two work packages, Argillite Disposal R&D and Crystalline Disposal R&D, support the achievement of the overarching mission and objectives of the Department of Energy Office of Nuclear Energy Fuel Cycle Technologies Program. These two work packages cover many of the fundamental technical issues that will have multiple implications to other disposal research work packages by bridging knowledge gaps to support the development of the safety case. The path-forward begins with the assumption of target dates that are set out in the January 2013 DOE Strategy for the Management and Disposal of Used Nuclear Fuel and High-Level Radioactive Waste (http://energy.gov/downloads/strategy-management-and-disposal-used-nuclear-fuel-and-high-levelradioactive- waste). The path-forward will be maintained as a living document and will be updated as needed in response to available funding and the progress of multiple R&D tasks in the Used Fuel Disposition Campaign and the Fuel Cycle Technologies Program. This path forward is developed based on the report of “Used Fuel Disposition Campaign Disposal Research and Development Roadmap (FCR&D-USED- 2011-000065 REV0)” (DOE, 2011). This document delineates the goals and objectives of the UFDC R&D program, needs for generic disposal concept design, and summarizes the prioritization of R&D issues.

Evidence and identification of microorganisms in argillite from Tournemire (France)

2010-01-01

Document available in extended abstract form only. Generalised corrosion is one of the main processes taken into account in the dimensioning of non-alloy steel overpacks for high level nuclear waste packages. However, the presence of microorganisms such as sulfate-reducing bacteria in the host rock in contact with these non-alloy materials may also influence localised corrosion processes, leading to a premature loss of the overpack watertightness. Available void and presence of free water are key conditions for bacterial development, which are not often met in an argillaceous environment. Nevertheless, microbial activity has been proven to occur in argillaceous formations such as the Opalinus Clay in the Mont Terri Underground Research Laboratory. Indigenous sulfate-reducing bacteria have also been put into evidence in MX-80 bentonite, a clayey material likely to be used as engineered barrier in many countries for nuclear waste repositories. The French Institute of Radioprotection and Nuclear Safety (IRSN) has been conducting a research program at the Tournemire experimental platform on the biodiversity of Toarcian argillite, aiming at assessing the potential development of a microbial activity in deep clayey environments, disturbed or not by an excavation. The occurrence of microbial processes in this formation was first shown by the study of time evolution of the chemical and isotopic composition of fracture groundwaters collected in several boreholes. These investigations suggested that aqueous sulfates and their isotopic composition were controlled by bacterial sulfate reduction. The presence of living sulfate-reducing bacteria in water samples from an air-drilled borehole crossing a tectonic fracture (MB1) was later shown. Thus, a characterisation of the microbial biodiversity of the Toarcian argillite was launched.

Dissolved chloride shows high δ{sup 37}Cl values, ranging between +6 and +80/00 vs. SMOC. The modeled profile considers diffusive exchange between connate seawater and meteoric freshwater. Transport parameters were obtained by radial diffusion experiments. Numerical modeling was performed with the coupled reactive-transport code Hytec. Simulations suggest a diffusive-exchange time of 85±10 Ma for Cl, which correlates with a major erosional period. Simulated δ{sup 37}Cl values between 1.002 and 1.003 agree with observed pore water δ{sup 37}Cl. This study strongly suggests that the dissolved chloride profile in the argillites results from diffusive exchange and indicates that unfractured argillites can provide good confinement. (authors)

Full Text Available Since its independence in 1991 Estonia has successfully overpassed the challenges of the transition period being in the present of one the most technologically developed nations of Europe. The present research is intended to evaluate the relationship between Estonian pro-market regulation, entrepreneurship and innovation. In order to reach relevant conclusions in this regard there have been used both qualitative and quantitative methods of analysis. In such a way, it could be comprehensively reviewed the process of Estonian economic development from a relatively underdeveloped USSR republic to an advanced innovation driven economy. The results show that pro-market governmental regulation has favourably influenced Estonian entrepreneurship, while it fostered country’s innovation capacities. It has been concluded that the economic “miracle” of Estonia has been at a great extent determined by proper government regulation oriented towards economic liberalisation.

Confinement properties evolution of the cap-rocks argillite-type under CO2 enriched-fluids: impact of the natural and artificial discontinuities

Berthe, G.

2012-01-01

This research is part of the studies of feasibility of CO 2 storage in deep geological strata, focusing more particularly on the evolution of the confinement properties of cap-rocks type argillite subjected to CO 2 enriched fluids. The argillite of Tournemire (Aveyron, France) were used as analog rocks, having identified what their weak points could be face to storage, namely their mineralogy, natural fractures filled with calcite and the presence of interfaces cement/argillite expected in filled injection wells. The 'through diffusion' experimental setup has been adapted to estimate (i) the possible modification of diffusive transport parameters recorded before and after acid attack for different radioactive tracers (tritium and chlorine-36) and non-radioactive tracers (deuterium and bromide) used to characterize samples of argillite of Tournemire and cement paste and (ii) the evolution of the chemical compositions of the solutions in the upstream and downstream reservoirs of diffusion cells during acid attacks. Finally, the analysis of solids was carried out in part by SEM-EDS, XRD and X-μTomography. Firstly, for all the samples studied, the values of the transport parameters determined before acid attack (effective diffusion coefficient and porosity) are consistent with those of the literature. In addition, it appears that all materials have reacted strongly to acid attacks. Thus, argillites saw their diffusion parameters increase up to a factor of two, especially for anionic tracers, and, whatever the proportion of carbonate minerals initially present in samples of argillite. The post-mortem observations have led to the identification of a zone of dissolution of carbonate minerals in them, but whose extension (400 microns or less) can not alone explain the significant degradation of the containment properties. Only unobservable phenomena during investigation scale, such as wormhole effects in porous network could be the cause. In addition, the samples of

Efficiency of Estonian grain farms in 2000 2004

Full Text Available The aim of this study is to analyse the efficiency of Estonian grain farms after Estonia’s transition to a market economy and during the accession period to the European Union (EU. The non-parametric method Data Envelopment Analysis (DEA was used to estimate the total technical, pure technical and scale efficiency of Estonian grain farms in 2000–2004. Mean total technical efficiency varied from 0.70 to 0.78. Of the grain farms 62% are operating under increasing returns to scale. Solely based on the DEA model it is not possible to determine optimum farm scale and the range of Estonian farm sizes operating efficiently is extensive. The most pure technically efficient farms were the smallest and the largest but the productivity of small farms is low compared to larger farms because of their small scale. Therefore, they are the least competitive. Since pre-accession period to the EU, large input slacks of capital have replaced the former excessive use of labour and land. This raises the question about the effects on efficiency of the EU’s investment support schemes in new member states.;

2011-03-01

Full Text Available The article examines how folk calendar holidays are represented in Estonian fairy tales. It introduces some views presented in folklore studies about the concept of time in fairy tales and finds parallels with them in the Estonian context. The analysis relies on the digital corpus of Estonian fairy tales (5400 variants, created from the texts found in the Estonian Folklore Archives by the Fairy Tale Project of the Department of Estonian and Comparative Folklore, University of Tartu. Folk calendar holidays occur in Estonian fairy tales relatively seldom; most often these are holidays that occupy a significant place in the Estonian folk calendar (Christmas, St. John’s Day, Easter, St. George’s Day. Calendar holidays are notably mentioned more often in tale types which remain on the borderline between the fairy tale and the legend or the fairy tale and the religious tale. In Estonian fairy tales, calendar holidays are used on three levels of meaning: (1 the holiday is organically associated with the tale type; it has an essential role in the plot of the tale; (2 to a certain extent, the holiday could be replaced by another holiday having an analogous meaning; (3 the holiday forms an unimportant or occasional addition to the tale.

Modelling the effective diffusion coefficient of anions in Callovo-Oxfordian argillite knowing the microstructure of the rock

International Nuclear Information System (INIS)

Diaz, N.

2009-01-01

After having presented the issue of radioactive waste storage, the concept of geological storage and its application in the Meuse/Haute-Marne underground laboratory, and described the Callovo-Oxfordian geological formation and the argillite transport properties, this research thesis aims at developing a prediction of these properties at a macroscopic scale for water and anions. A first part presents the different experimental means implemented to acquire the diffusion coefficients for the studied materials (Callovo-Oxfordian argillite and purified Puy illite), and the spatial organisation of minerals by LIBS probe-based mapping to highlight a relationship between rock microstructure and its transport macroscopic properties. The next part presents the models which have been developed at the nanometer and micrometre scale to predict the diffusion coefficients. Experimental results are then compared with computed values

Revisiting the Estonian Cyber Attacks: Digital Threats and Multinational Responses

Directory of Open Access Journals (Sweden)

Stephen Herzog

2011-01-01

Full Text Available In April 2007, the Estonian Government moved a memorial commemorating the Soviet liberation of the country from the Nazis to a less prominent and visible location in Tallinn. This decision triggered rioting among Russian-speaking minorities and cyber terrorism targeting Estonia's critical economic and political infrastructure. Drawing upon the Estonian cyber attacks, this article argues that globalization and the Internet have enabled transnational groups—such as the Russian diaspora—to avenge their grievances by threatening the sovereignty of nation-states in cyberspace. Sophisticated and virtually untraceable political "hacktivists" may now possess the ability to disrupt or destroy government operations, banking transactions, city power grids, and even military weapon systems. Fortunately, western countries banded together to effectively combat the Estonian cyber attacks and minimize their effects. However, this article concludes that in the age of globalization, interdependence, and digital interconnectedness, nation-states must engage in increased cooperative cyber-defense activities to counter and prevent devastating Internet attacks and their implications.

Mechanical modeling of nuclear waste disposal in argillite at the Nevada Test Site

International Nuclear Information System (INIS)

Thomas, R.K.; Lappin, A.R.

1979-01-01

Numerical calculations for a near surface heater experiment in argillite conducted at the Nevada Test Site were performed using the finite element code ADINA assuming a two-dimensional axisymmetric geometry. The existence and extent of the region of tensional opening of joints surrounding the heater, predicted by the mechanical model, were confirmed by posttest borehole inspection, permeability measurements, and drillback. Exrapolation of near surface heater model to repository depths reveals the necessity for prior knowledge of the mechanical properties and state of stress in-situ. The extent of the joint opening zone, for example, is not altered by changes in the elastic modulus at the near surface, but is significantly decreased beyond certain depths depending upon the in-situ elastic modulus. Results of these calculations are presented. To further define the behavior at depth, and place bounds on the joint opening zone, far-field calculations were performed for a generic repository in argillite. Both spent fuel and high level waste heat sources were considered at different burial densities and depths. Results of a parametric study are presented in which the mechanical properties, in-situ stresses, and waste heat sources were varied

Experimental evidence for self-sealing of fractures in argillites

International Nuclear Information System (INIS)

Zhang, Chun-Liang

2010-01-01

Document available in extended abstract form only. In argillaceous rocks, self-sealing of fractures generated by the excavation of underground repositories can be expected due to combined impact of rock compression, backfill resistance, and clay swelling during the post-closure phase. The sealing process is determined by the deformability and swelling capacity of the host rock and the backfill as well as by the boundary conditions. As a crucial factor for the long-term safety of repositories, the sealing behaviour of fractures in argillites has been experimentally investigated by GRS on the Callovo-Oxfordian argillite (COX) and the Opalinus clay (OPA) under relevant repository conditions. Comprehensive laboratory tests were carried out on artificially-fractured samples of different sizes (diameter/length = 50/50 - 280/600 mm) and shapes (cylinder and hollow cylinder) under various confining stresses, fluid pressures, and temperatures. The sealing of fractures was detected by measurement of deformation, permeability and wave velocity variations. Following previous studies in which the sealing of fractured samples was determined by gas flow at ambient temperature, additional tests were performed by flowing synthetic pore water through fractures under different confining stresses and at elevated temperatures. Typical results of the tests are presented in this paper. Current results of the ongoing long-term permeability measurements on fractured COX and OPA samples (D/L = 50/50 mm) are summarized, some of which were pre-heated up to high temperatures of 50, 100 and 150 deg. C. In those tests, synthetic pore water was flowed through at injection pressure of 1 MPa, confining stresses of 2 to 3 MPa, and elevated temperatures from 20 to 90 deg. C. All fractured samples showed the same high initial gas permeability of 3.10 -12 m 2 . As the water was injected, the permeability dropped down by three to five orders of magnitude to 10 -15 to 10 -18 m 2 , depending on the

Understanding the behavior of a clay mineral-rich rock submitted to different physical-chemical perturbations is important for assessing the safety of nuclear waste disposal facilities in the corresponding geological formations. In this work we studied the effect of rock desaturation on the CO{sub 2} partial pressure signature of the Callovo-Oxfordian argillite. This integrated study, which combines experiments and geochemical modeling, points out the primary role of capillary forces on the chemical equilibria. In particular, it was possible to model, without any fitting parameters, the experimental decrease of pCO{sub 2} as a function of decreasing water content in the argillite. Moreover, this application to a complex natural system is an example of confirmation of the theoretical concepts of geochemistry in capillary contexts and is promising for dealing with other natural and industrial systems.

2013-12-01

Full Text Available The article analyses tale type The Woman as Wolf, which is one of the most popular folk tales in the Estonian Folklore Archives and is represented there both in the form of a fairy tale and in the form of a legend. The vast majority of the versions of The Woman as Wolf were written down in the first part of the 20th century within Estonia and where recorded from Estonians. The article introduces the content of the tale, the origin of the first records from the early 19th century, and the dissemination area of the tale, which remains outside Western Europe: apart from the Estonian versions there are Sami, Karelian, Vepsian, Livonian, Latvian, Lithuanian, Russian, Ukrainian and Belarusian versions. While in almost all the Estonian versions the main protagonist is transformed into a wolf, in most of the versions written down in other areas and ethnic groups, another animal or bird replaces the wolf. The author is of the opinion that the Finnic area is central to the distribution of the folk tale The Woman as Wolf. The animal the woman is transformed into in the plot would not have been a wolf in earlier times. The article provides an explanation why the wolf is predominant in Estonian written sources. For that purpose the ways in which the wolf and werewolf were perceived in earlier Estonian folk belief are introduced. At the end of the article interpretation of the folk tale is provided. The author states that the plot and some of the motifs found in this folk tale reflect the difficulties women had in submitting to the norms and values of patriarchal order within their society.

Full Text Available The article reports the results of the study on the critical success factors and related information needs in Estonian industry conducted in 1999. Data were collected by interviews with 27 managers and engineers from 16 manufacturing companies in various industries. Most of the critical success factors taken up were related to marketing, information management, quality management, product development and technological innovations. The information needs of managers and engineers were related to competitors, customers, markets, technology, regulations, etc. Some identified CSFs expressed also priorities for development by Estonian economic authorities: to support the implementation of new technologies and introduction of quality management methods. The finding that information management was perceived as a very critical area supports the result of the recent Finnish study on CSFs.

Rb-Sr geochronology of coarse-grained greywackes and argillites from the Coffs Harbour Block, eastern Australia

International Nuclear Information System (INIS)

Graham, I.J.; Korsch, R.J.

1985-01-01

The Coffs Harbour Block, eastern Australia, includes a sequence of turbidity-current-deposited greywackes and argillites dominated by quartz-poor to quartz-intermediate, volcanic-lithic and feldspathic types. The rocks have a common provenance consisting of dacite with minor andesite and rhyolite, derived from a continental margin volcanic arc. Rb-Sr whole-rock dating of coarse-grained greywackes and argillites suggests that low-grade regional metamorphism (prehnite-pumpellyite to lowest greenschist facies) has completely equilibrated sediments of all grain sizes, giving an age of 318 +- 8 Ma. A subsequent metamorphism which produced thermal biotite on a regional scale over the southern part of the area, re-equilibrated only the fine-grained sediments 238 +- 5 Ma ago; the coarse-grained sediments were unaffected isotopically and still lie on the older isochron. The wide variations in sandstone petrographic modes imply that the older isochron represents neither the age of volcanism in the magmatic arc nor the age of sedimentation at the deposition site, but rather dates the time of earlier metamorphism.

McVey, D.F.; Lappin, A.R.; Thomas, R.K.

1979-01-01

A preliminary evaluation of the in-situ thermomechanical response of argillite to heating was obtained from a near-surface heater test in the Eleana Formation, at the United States Department of Energy, Nevada Test Site. The experiment consisted of a 3.8 kW, 3-m long x 0.3-m diameter electrical heater in a central hole surrounded by peripheral holes containing instrumentation to measure temperature, gas pressures, and vertical displacement. A thermal model of the experiment agreed well with experimental results; a comparison of measured and predicted temperatures indicates that some nonmodeled vertical transport of water and water vapor occurred near the heater, especially at early times. A mechanical model indicated that contraction of expandable clays in the argillite produced a region 1.5 - 2.0 m in radius, in which opening of preexisting joints occurred as a result of volumetric contraction. Results of thermal and mechanical modeling, laboratory property measurements, experimental temperature measurements, and post-test observations are all self-consistent and provide preliminary information on the in-situ response of argillaceous rocks to the emplacement of heat-producing nuclear waste

Full Text Available The article deals with the development in Russian-Estonian relations during the crises of 2007 and 2014, taking into consideration the balance between political and economic factors in the decision-making by Estonian government. A number of special aspects, trends and problems in trade and investment ties are detected. The aim of the study is to uncover key motivation behind the actions of both Russia and Estonia, to identify the drivers for economic and political development in the region, and to work out recommendations to adjust them. The questions put forward by the authors of this article could not be more topical at the time, when Russian economic situation is obviously getting worse and capital flight (to the neighboring EU Member States is likely to increase. The method of the study is comparative analysis of the impact on economic ties made by Russian-Estonian crisis of 2007 and the current international tension around Ukraine. The regional fossil fuel market and the possibilities of Gazprom involvement in its development are also analyzed. It is concluded that political motives are still important for Estonian decisionmaking, though they are balanced out by measures of business support (despite some of these measures being taken by the EU bodies. The role of political factor for the Russian side is increasing. It is acknowledged that there is a growing number of missed economic opportunities in the Russian Northwest.

Overview of the Estonian Biofuels Association activities

Due to global warming and environment pollution because of widespread use of fossil fuels there are already tendencies to stabilize and decrease the consumption of these energy resources and take into use more renewable energy resources. Estonian Biofuels Association (EBA) is a non-profit association, which was founded on 8. of May 1998 in Tallinn. The EBA is an independent and voluntary alliance of its members. Fields of activity of the EBA are by biofuels research, developing and evaluation to engage environmental, biofuels and energy saving. EBA members are: energy consultants, scientists, as well as fuel suppliers, DH-companies, technology suppliers, energy service companies etc. The members of EBA are involved in different projects in Estonia, where biomass are produced and used for heating, where wood, waste, peat, rape oil and biogas resources are examined and put into use, and also projects which deal with energy saving and environment friendly equipment production for using biofuels. During our short experience we have noticed that people in Estonia have become more aware of biomass and their use, so the development of environment friendly and sustainable energetics will continue in Estonia. Available biofuels in Estonia could compete with fossil fuels if burnt rationally with high technology equipment. EBA members are convinced that biomass have perspective and that they could play an important role in improving Estonian economic and environmental situation. Modem biomass combustion devices are taken into use more the faster general wealth increases and EBA can raise people's awareness of bio fuel subject through special, courses and media. We want Estonian energy policy to develop towards widespread use of renewable energy resources, which would save energy and environment improve nation's foreign trade balance and create jobs mainly in rural areas

2017-09-01

Full Text Available This article attempts to explain the relationships between journalists, politics and the state from the perspective of collective autonomy, that of the professional organization of journalists. The case of Estonian Journalists’ Union demonstrates the complexity and historical contingency of professional autonomy of journalism. The development of the Estonian journalists’ organization occurred as a sequence of transformations from the Estonian Journalists’ Association to the Estonian Journalists’ Union to the Soviet type journalists’ union, and lastly to an independent trade union. This sequence was disrupted by several fatal breakdowns that changed not only the character of the association, but also professional values, the whole occupational ideology and the conditions of the existence of journalism as a profession in Estonia.

The most comprehensive epidemiological project ever performed in Estonia - The Estonian Study of Chernobyl Cleanup Workers - was the joint effort of researchers from Estonia, Finland and USA. Until September 1999, the results of this study were published in English only. To familiarize the readership of 'Eesti Arst' with the major study findings, the abridged versions of four original papers from 'Radiation Research' are presented in the current issue of the journal. For the Estonian epidemiologists, the work under this project that consists of eight sub projects was a real challenge. In the course of the study, skills were developed in writing a study protocol, preparing a questionnaire, progress reporting, documenting the structure of databases, record linkage, and problem solving. It was an exciting experience to work with top scientists like William Bigbee, John Boice, Timo Hakulinen, Ronald Jensen and Gayle Littlefield. (author)

Microbial diversity of the 180 million-year-old Toarcian argillite from Tournemire, France

Urios, Laurent; Marsal, François; Pellegrini, Delphine; Magot, Michel

2012-01-01

Even though the microbiology of various subsurface environments has been investigated for more than 30 a, the microbial diversity of deep argillaceous media is still poorly known. In the context of radioactive waste disposal in clayey formations, the consequence of microbial activity is of concern regarding e.g. the corrosion of metallic components. The purpose of the present work was to characterise the cultivable microbial diversity of different zones of the Toarcian argillite of Tournemire (France) as a preliminary indication regarding the potential of development of microbes in such subterrestrial environments. Cores were drilled in the Excavation Damaged Zone (EDZ) and in the deeper undisturbed zone of the argillite layer, as well as in a zone intersected by a geological fault. Samples from the wall of the drift were also collected. Microorganisms were cultivated from all samples, but the biodiversity differed depending mainly on the O 2 and moisture content. Aerobic bacteria were identified on the wall, in the EDZ and in the wet faulted area, whereas SO 4 -reducing bacteria were isolated from the wet faulted area only. Anaerobic heterotrophs were cultivated from all zones. One hundred and twelve isolates were identified. Small ribosomal subunit gene sequences showed that bacteria of the undisturbed zone were affiliated to three genera only, whereas the three other sampled zones harbour more diverse microflora, including isolates closely related to taxons characterized from subsurface, deep marine and polar environments.

Sustainable development outlooks of the Estonian energy sector for convergence with the European Union countries

The article presents an overview of a research conducted in the Estonian Inst. of Economics and the Estonian Energy Research Inst. with the objectives to: analyse the dynamics of the main Estonian energy use indicators over the last 8-10 years with the background of general macroeconomics developments; compare these indicators with the respective energy indicators in the European Union Member States and Candidate Countries; evaluate Estonia's potential to catch up by the energy use efficiency (GDP energy intensity) of the average level of EU countries, modelling our possible development scenarios of GDP and TPES. The research results indicates several positive development tendencies (e.g. reduction of TPES and CO 2 emissions with the background of economic growth) in the Estonian energy sector, as well as convergence with the EU countries in terms of GDP energy intensity. Unfortunately, the model analysis results demonstrate that it takes a lot of time for Estonia to reach the current EU level - even under the most favourable GDP and TPES development conditions, 25-30 years. The primary reason is the very low level of our GDP per capita compared to the EU countries. (author)

On the compression behaviour of the Callovo-Oxfordian argillite

2010-01-01

Document available in extended abstract form only. In the framework of research into radioactive waste disposal, it was decided to investigate some aspects of the volume change behaviour of the Callovo-Oxfordian argillite, a possible host rock in which the ANDRA underground laboratory of Bure (East of France) has been excavated. To do so, high pressure oedometers able to apply a maximum load of 113 MPa were used. Oedometers are widely used in Soil mechanics but not so much in Rock mechanics. In spite of applying combined stress/strain conditions (controlled vertical stress with no radial strain allowed) in which the radial stress is not controlled, their advantage is to be simple and robust to use (easy long term stress control and strain measurements). They provide a simple way to investigate the elastoplastic behaviour of soils, particularly regarding the elastic modulus, yield point and plastic compressibility. A high pressure oedometer developed at UR Navier/CERMES was used. The apparatus is a double lever arm device able to apply a maximum axial stress of 113 MPa on a specimen contained in a rigid ring of diameter 38 mm. The sample is 10 mm high. Vertical strains are monitored by using an electronic strain transducer connected to a data acquisition system. Previous calibration of the system was carried out by running a test with no sample in the ring so as to account for the effects of the compression of the top and bottom porous disks, of cell and of the piston. A reversible response of the system was observed after applying various loading cycles between 0 and 113 MPa. The specimen was trimmed by using a diamond corer of corresponding diameter and placed inside the oedometer ring. The top and bottom faces of the sample were polished by using sand paper so as to get two flat, regular and parallel faces. The ring was placed into the oedometer cell with dry porous stones and specimen was loaded under 1 MPa to ensure good contact with the porous stones and the

Full Text Available The article concentrates on Estonian novels depicting Soviet prison camps in the 1940s and 1950s. The goal is to map themes, motifs and characteristics in such novels, concentrating on various taboos and rules in the prison camp environment. For a long time the Soviet prison camp theme was not publicly discussed in Estonia due to political reasons. Texts dealing with prison camps could appear in print only outside the Soviet Union; the way Estonians saw these historical events and hellish experiences were depicted mostly in exile novels. Most notable are the novels by Arved Viirlaid (b. 1922, e.g., Kes tappis Eerik Hormi? (Who Killed Eerik Horm? (1974, Surnud ei loe (The Dead do not Read (1975, Vaim ja ahelad (Mind and Chains (1961. Estonian prison camp novels can be seen as “the literature of testimony”, to use the term by Leona Toker. Dramatic historical events are written down to record the events and to show the inhumane nature of Soviet society. These records of the dramatic past follow certain patterns and create certain self- and hetero-images. A prison camp is a closed territory within a closed territory; prison camps can be seen as small models of Soviet society. Prison camp novels give a detailed view of the environment of the prison camp, its inhabitants and activities. Two central aspects are labour and food; the life of the prisoner whirls around these. The most important thing is to survive, which often leads to moral decline, e.g., stealing, cheating. However, there are lines Estonians do not cross, e.g., cannibalism or homosexual relationships with superiors. Estonians are always depicted as political prisoners (not common criminals and heterosexuals, while Russians are portrayed mainly as criminals and often also as homosexuals. Another important component of the image of the Estonians is their enterprising spirit and ability to manage even under very difficult conditions. Therefore, several oppositions can be identified, e

Estonian wind climate

Kull, Ain

1999-01-01

Estonia is situated on the eastern coast of the Baltic Sea. This is a region with intensive cyclonic activity and therefore with a relatively high mean wind speed. Atmospheric circulation and its seasonal variation determine the general character of the Estonian wind regime over the Atlantic Ocean and Eurasia. However, the Baltic sea itself is a very important factor affecting wind climate, it has an especially strong influence on the wind regime in costal areas. The mean energy density (W/m 2 ) is a wind energy characteristic that is proportional to the third power of wind speed and describes energy available in a flow of air through a unit area. The mean energy density is a characteristic which has practical importance in regional assessment of snowdrift, storm damage and wind energy

This thesis deals with the hydro-mechanical behaviour of argillite. Classical Biot theory is shown to be badly adapted to the case of argillite. An original state equation is then built by use of homogenization tools, and takes into account the microstructure of argillite as well as physical phenomena happening inside the material, like the swelling overpressure inside the clay particles or the capillary effects in the porous network. This state equation explains some experiments which were not by the classical Biot theory. It is then improved by integrating the experimental data that are the dependency of the elasticity tensor with the saturation degree and the existence of a porosity surrounding the inclusions. Combined with the monitoring of length variation under hydric loading, this relevant state equation permits one to determine the Biot tensor of argillite. Since this state equation is coupled with the hydric state of the material, one is interested in modelling the variation of the saturation degree during a drying process. Two transport models are studied and compared, then a model for the porous network is proposed in order to explain the unusual permeability measurements. (author)

The report describes the development and summarizes the results of the project Cancer incidence and thyroid disease among Estonian Chernobyl clean-up workers. One of the goals of the report is to give research protocols and questionnaires for researchers involved in other studies. Eight previously published articles are also included summarizing the results. The development of the collaboration work of the project is described in the introduction of the report. Epidemiological methods are described in an article complemented by the protocol and English version of the questionnaire administered to all cleanup workers, as well as the data collection form of the thyroid study. The results from biological biodosimetry using both glycophorin A and FISH methods have shown that the radiation doses received by the Chernobyl cleanup workers were relatively low. Thyroid nodularity was not associated with any radiation exposure characteristic in the thyroid screening study. Estonian Chernobyl cleanup workers were followed up for cancer incidence through the Estonian Cancer Registry. No cases of leukemia or thyroid cancer were observed by the end of 1993. It is too early to observe possible effect on other types of cancer. However, mortality from suicides was increased compared with general population. Further follow-up and the extension to other Baltic countries in the future will undoubtedly strengthen the study. There are also plans for future projects covering areas from psychosocial factors to radiation biology

Layoffs have increased the number of unemployed; some of those who have lost employment opt for social assistance benefits, but some others decide to become entrepreneurs. Many enterprising people in Estonia have set up a family enterprise, mainly in the sphere of services, agriculture and tourism. The Estonian entrepreneurship policy supports enterprising people and approves of entrepreneurship as a promoter of national economic development. One of the most positive qualities of family enterprises is their short decision-making chain, which ensures rapid implementation of the strategy.

Utilisation of Estonian energy wood resources

1996-12-31

In the end of the Soviet period in the 1980s, a long-term energy programme for Estonia was worked out. The energy system was planned to be based on nuclear power and the share of domestic alternative sources of energy was low. The situation has greatly changed after the re-establishment of the Estonian independence, and now wood and peat fuels play an important role in the energy system. Energy consumption in Estonia decreased during the period 1970-1993, but this process has less influenced the consumption of domestic renewable fuels - peat and wood. It means that the share of these fuels has grown. The investment on substitution of imported fossil fuels and on conversion of boiler plants from fossil fuels to domestic fuels has reached the level of USD 100 million. The perspectives of the wood energy depend mainly on two factors; the resources and the price of wood energy compared with other fuels. The situation in wood market influences both the possible quantities and the price. It is typical that the quickly growing cost of labour power in Estonia is greatly affecting the price of energy wood. Though the price level of fuel peat and wood chips is lower than the world market price today, the conditions for using biofuels could be more favourable, if higher environmental fees were introduced. In conjunction with increasing utilisation of biofuels it is important to evaluate possible emissions or removal of greenhouse gases from Estonian forests 3 refs.

Document available in extended abstract form only. During long-term repository of high and intermediate level nuclear waste in deep argillaceous geological formation, steel containers will corroded and organic material will be irradiated. The two processes lead mostly to hydrogen production. This study deals with the numerical modelling of the gas migration in both the host formation and a bentonite plug, with an emphasis on coupling between the gas transfer and the mechanical strains and stresses. More particularly the study aims to support the design of the PGZ in situ experiment that will be performed by Andra in its underground laboratory at Bure. The objective of the experiment is the analysis of the dynamics of the bentonite plug re-saturation, studying the competition between the liquid water coming from the argillite and a gas injection. The modelled experiment consists of a borehole drilled in rock clay, inside which a plug of MX-80 bentonite is set. The bentonite is naturally re-saturated by water coming from the host formation. At the same time a gas pressure, higher than the initial water pressure in the host rock, is imposed at both ends of the plug. The developed model takes into account the coupling between the mechanical behaviour and the water and gas transfers in undisturbed geo-materials. It manages explicitly liquid and vapour water, gaseous and dissolved hydrogen. Elastoplastic and non-linear elastic model are used to model the behaviour of, respectively, the argillaceous rock and the bentonite. The numerical results show the small desaturation obtained in bentonite and argillite. The influence of the coupling of the mechanic on the water and gas transfers is thus limited (due to the Bishop's effective stress). The swelling of the bentonite plug is not hindered by the gas migration and the confining effect of the engineered barrier is maintained. An analysis is made of the influence of the main transfer rock properties on the gas pressure

This study examined the smoking habits and attitudes towards smoking among Estonian physicians. Cross-sectional data for 2668 physicians were gathered by a self-administered postal survey. The current smoking prevalence was 24.9% for male physicians and 10.8% for female physicians. The percentages of ex-smokers were 32.9 and 16.8%, respectively. Smoking prevalence among physicians was below the levels reported for the highest educational bracket of the total population in Estonia. Non-smoking physicians had more unfavourable views towards smoking than those who smoked. The majority of physicians were aware of the association between smoking and various diseases, with significant differences between smokers and non-smokers. Non-smoking physicians were more active in asking patients about smoking habits than those who smoked. Most Estonian physicians, especially those who smoked, failed to perceive themselves as positive role models. This study found a lower prevalence of smoking among physicians compared with the general population, and demonstrated the impact of personal smoking on physicians' attitudes towards smoking. The results provide an important challenge to medical education in Estonia.

Soil organic carbon (SOC) determines ecosystem functions, influencing soil fertility, soil physical, chemical and biological properties and crop productivity. Therefore the spatial pattern of SOC stocks and its appropriate management is important at various scales. Due to climate change and the contribution of carbon store in the soils, the national estimates of soil carbon stocks should be determined. Estonian soils have been well studied and mapped at a scale 1:10,000. Previous studies have estimated SOC stocks based on combinations of large groups of Estonian soils and the mean values of the soil profile database, but were not embedded into the geo-referenced databases. These studies have estimated SOC stocks of Estonian arable soils 122.3 Tg. Despite of available soil maps and databases, this information is still very poorly used for spatial soil modelling. The aim of current study is to assess and model spatial pattern of SOC stocks of arable soils on a pilot area Tartu County (area 3089 sq km). Estonian digital soil map and soil monitoring databases are providing a good opportunity to assess SOC stocks at various scales. The qualitative nature of the initial data from a soil map prohibits any straightforward use in modelling. Thus we have used several databases to construct models and linkages between soil properties that can be integrated into soil map. First step was to reorganize the soil map database (44,046 mapping units) so it can be used as an input to modelling. Arable areas were distinguished by a field layer of Agricultural Registers and Information Board, which provides precise information of current land use as it is the basis of paying CAP subsidies. The estimates of SOC content were found by using the arable land evaluation database of Tartu from the Estonian Land Board (comprising 950 sq km and 31,226 fields), where each soil type was assessed separately and average SOC content grouped by texture was derived. SOC content of epipedon varies in

To compare smoking behaviour, attitudes and opinions towards smoking and smoking cessation among Estonian and Finnish physicians. A cross-sectional postal survey using a self-administered questionnaire was carried out among 2,480 Estonian and 2,075 Finnish physicians. Daily smoking prevalence was higher among Estonian physicians than among their Finnish counterparts in both male (18.6% and 6.7%) and female (6.6% and 3.6%). Compared to Estonia, physicians in Finland more often agreed that smoking is very harmful to their health, that trying to convince people to stop smoking is their responsibility and that smoking prevention should be part of the normal and special training of health professionals. In both countries, non-smoking physicians held more unfavourable attitudes towards smoking than those who were smoking. Physicians' own smoking patterns and quitting behaviour are important because physicians serve as models for their patients and play a key role in the reinforcement of smoke-free health facilities. These results remain a challenge to medical educators, especially in Estonia. Estonia needs to improve medical education in terms of motivating physicians to ask about the smoking patterns of their patients and of training medical students and resident physicians to counsel their patients to stop smoking.

Predicting the diagenetic evolution of argillite repositories: application of flow-through reaction cells

International Nuclear Information System (INIS)

Warr, L.; Clatter, N.; Liewig, N.

2005-01-01

In order to successfully predict the diagenetic evolution of argillite repositories we need to know i) which reactions occur under a defined set of conditions, ii) how these reactions modify the material properties of the argillite seal, and iii) how fast these chemical reactions take place. Based on the application of thermodynamics, and the construction of activity diagrams for low temperature mineral phases (e.g. Velde 1992), fair predictions of mineral stability can be made under a given set of physical and chemical conditions. Such predictions are strengthened by examining natural mineral reactions preserved in the geological record, in combination with results obtained from controlled laboratory experiments. Changes in the material behavior can also be reasonably assessed, as the basic physical and chemical properties of argillaceous rocks of varying mineralogy are well documented in the petrophysical and engineering literature (e.g. Bell, 1999). Probably the most difficult task, however, is to assess the rates of the chemical reactions involved. This difficulty reflects our poor knowledge of the reaction kinetics for these low-temperature, fine-grained mineral materials, and apparent differences between rates estimated from natural and experimental systems. A new approach to monitoring the reaction kinetics of fine-grained minerals in percolating solution has been developed using flow-through reaction (wet-cell) chambers. These devices can be routinely mounted onto the X-ray diffractometer for in-situ measurements of the sample. With the aid of a cap to maintain constant volume, the device can be subjected to diagenetic or hydrothermal conditions (<150 C). First results are here presented for the alteration of Callovo-Oxfordian shales in a reactive simple young fluid (strongly alkaline, pH ca. 13) at 90 C, designed to simulate the alteration of concrete at the repository site.

At present, the crushed Callovo-Oxfordian (COx) argillite powder is proposed as an alternative backfilling material in France, which will be constructed in the engineering barrier of high-level radioactive waste (HLW) repository. In this investigation, the compression behavior of two crushed COx argillite powders (coarser one and finer one) was studied by running l-D compression tests with several loading-unloading cycles. After the final dry density 2.0 g/cm 3 was reached, the specimen was flooding with distilled water and the evolution of axial stress was studied during saturation process. The effects of initial axial stress level and grain size distribution (GSD) on hydro-mechanical behaviour of compacted specimen were analyzed. The results show that the compression curves are significantly influenced by the GSD of the soils. To obtain the same degree of compaction, the axial stress applied to finer soil is much higher than that of coarser soil. In addition, the compression index of the finer soil is bigger than that of coarser soil. The swelling index at initial water content increases with the dry density and seems to be independent of the GSD. During saturation, the initial lower axial stress causes obvious swelling behavior for both the coarser and finer powder samples and the corresponding axial stress increase gradually. At initial higher axial stress condition, monotone collapse behavior is observed for the coarser powder samples. Whereas the axial stress decrease firstly, then increase and finally decrease again for the finer powder samples. After saturation, the equilibrium axial stresses of finer powder samples are higher than that of coarser powder samples. (authors)

This work is performed in the general context of the project of underground disposal of radioactive waste, undertaken by the French National Radioactive Waste Management Agency (ANDRA). Due to its strong density and weak permeability, the formation of Callovo-Oxfordian argillite is chosen as one of possible geological barriers to radionuclides. The objective of the study to develop and validate a non linear homogenization approach of the mechanical behavior of Callovo-Oxfordian argillites. The material is modelled as a composite constituted of an elasto(visco)plastic clay matrix and of linear elastic or elastic damage inclusions. The macroscopic constitutive law is obtained by adapting the incremental method proposed by Hill. The derived model is first compared to Finite Element calculations on unit cell. It is then validated and applied for the prediction of the macroscopic stress-strain responses of the argillite at different geological depths. Finally, the micromechanical model is implemented in a commercial finite element code (Abaqus) for the simulation of a vertical shaft of the underground laboratory. This allows predicting the distribution of damage state and plastic strains and characterizing the excavation damage zone (EDZ). (author)

Identity and Othering in Past and Present: Representations of the Soviet Era in Estonian Post-Soviet Textbooks

Katrin Kello

2018-02-01

Full Text Available This paper analyses representations of the ‘core Soviet era’ (1945-1985 in Estonian post-Soviet history textbooks (1989-2016. Attitudes towards the Soviet system have been a rich resource for identity building, and hence a powerful political tool across the whole of the post-Soviet block. Based on an analysis of sections about the Soviet era in Estonia in 21 textbooks, the paper takes a look at how textbooks reflect broader processes of social meaning making, identity building and othering after a profound social and political turn. In 1989 and during the early 1990s, perspectives and narratives in Estonian history textbooks were closely related to social memory and national politics, enacting a specific social representation of the Soviet era that dominated the Estonian-speaking public space during the 1990s. The Soviet era, Russia and local Russians became the main Others for Estonia and Estonians. Over time, public discourse has diversified. The national curriculum and textbooks, however, still maintain the canon that formed in 1990s and thus reflect earlier sentiments. Apart from the increasing salience of Soviet-era daily life in more recent textbooks, the thematic choices and emphases have changed little since the 1990s. Therefore, even if the style of writing has ‘cooled down’, issues of identity preservation, resistance and accommodation, together with a saliently negative representation of wrongdoings by the Soviet system, still prevail. On the one hand, this testifies to the resilience of an established tradition in the textbook genre in general. On the other hand, it reflects the dominance of an ethnocentric tradition in Estonian history textbook writing. The paper discusses the implications of these findings for interethnic relations in Estonia.

Full Text Available Economic weights for milk carrier (water plus lactose, fat and protein yields, calving interval, age at first service, interval between the first service and conception of heifers and length of productive life of Estonian Holsteins were estimated under assumed milk production quota and for non-quota conditions. A bio-economic model of an integrated production system of a closed herd was used. Economic values of milk carrier yield and length of productive life differed between quota and non-quota conditions, but there were only minor differences between those marketing systems in economic values for functional traits. The standardised economic values of the most important traits varied in magnitude between18 to 81% of the economic value for milk yield. Discounting had a substantial impact on the economic value of length of productive life. When defining the breeding objective for Estonian Holstein, the interval between the first service and conception of heifers, and the length of productive life should be included in the breeding goal along with the traits with the highest economic value, milk, fat and protein yield. In the optimum breeding objective, relative weights of production vs. functional traits were 79 and 21%, respectively.;

Iron/argillite interactions in radioactive waste disposal context: Oxidising transient and bacterial activities influence

The design of a high-level radioactive waste (HLW) disposal facility developed by Andra (2005) in France involves emplacing metallic materials (containers, overpacks, liner) into a geological argillaceous formation. During the operational phase, ventilation of handling drifts will keep oxidising conditions at the front of disposal tunnels. Therefore, an oxidising transient may take place in parts of these tunnels in the post-closure phase possibly over several years. During this transient period, the environment of the disposal cell will evolve towards reducing and saturated conditions close to the equilibrium state of the original underground argillaceous formation. Moreover, high temperature conditions above 50 deg. C may be encountered in this environment over a few hundred years. Uniform corrosion represents the main type of degradation of metallic materials for the long term. The oxidising transient will be characterised by high corrosion rates (e.g. localised corrosion) due to the presence of oxygen whereas during the following anoxic stage, the main alteration factor will originate from the pore water associated with lower corrosion rates. In any case, metallic materials corrosion will lead to the release of aqueous iron, which may induce alteration of the favourable confining properties of the clayey materials. In this context, reactive pathways related to the metal corrosion under oxidising conditions and then followed by reducing conditions remain to be further understood (evolution of pH, redox and influence of temperature). Furthermore, some other significant issues remain open, in particular the dissolution/precipitation processes, the argillite perturbation extent and the effects of these transformations on the confining properties of materials. The presence of micro-organisms in deep argillaceous environment and the introduction of new bacterial species in the repository during the operational phase raise the question of their survival under real

Smoking surveys among physicians have proved useful in highlighting the importance of physicians as healthy life style exemplars and role models in tobacco control and smoking cessation. The aim of this study was to give an overview of smoking behaviour among Estonian physicians from 1982 to 2014. Three cross-sectional postal surveys using a self-administered questionnaire were carried out among all practising physicians in Estonia. The number of physicians participating in this study was 3786 in 1982, 2735 in 2002, and 2902 in 2014. Data analysis involved calculating the age-standardized prevalences of smoking, prevalences of smoking by age group and mean age of smoking initiation. A non-parametric test for trend was used to assess significant changes in smoking over time. Age-standardized prevalence of current smoking among men was 39.7% in 1982, 20.9% in 2002, and 14.3% in 2014 and among women 12.2%, 8.0%, and 5.2%, respectively (p smoking among men and women was in age groups under 35 (from 55.2% to 16.7% and from 16.7% to 2.8%, respectively) and 35-44 (from 47.1% to 8.3% and from 19.5% to 5.1%, respectively) (p smoking initiation decreased from 20.4 to 19.3 among men and from 24.5 to 20.4 among women over the study period. In 1982-2014, smoking prevalence among Estonian physicians declined substantially. This may influence the willingness of society to recognize the health consequences of smoking which could give a support to the decline of the smoking epidemic in the country. Differences between smoking among male and female physicians persisted over the study period, but mean age of smoking initiation decreased. A further decline in smoking among Estonian physicians should be encouraged by special efforts targeted at physicians.

Despite diagnostic and therapeutic advancements, the burden of cancer is still increasing worldwide. Toxicity of current chemotherapeutics to normal cells and their resistance to tumor cells highlights the urgent need for new drugs with minimal adverse side effects. The use of natural anticancer agents has entered into the area of cancer research and increased efforts are being made to isolate bioactive products from medicinal plants. To lead the search for plants with potential cytotoxic activity, ethnopharmacological knowledge can give a great contribution. Therefore, the attention of this review is devoted to the natural remedies traditionally used for the cancer treatment by Estonian people over a period of almost 150 years. Two massive databases, the first one stored in the Estonian Folklore Archives and the second one in the electronic database HERBA ( http://herba.folklore.ee/ ), containing altogether more than 30 000 ethnomedicinal texts were systematically reviewed to compile data about the Estonian folk traditional experiences on natural anticancer remedies. As a result, 44 different plants with potential anticancer properties were elicited, 5 of which [Angelica sylvestris L. (Apiaceae), Anthemis tinctoria L. (Asteraceae), Pinus sylvestris L. (Pinaceae), Sorbus aucuparia L. (Rosaceae), and Prunus padus L. (Rosaceae)] have not been previously described with respect to their tumoricidal activities in the scientific literature, suggesting thus the potential herbal materials for further investigations of natural anticancer compounds.

This work is performed in the general context of the project of underground disposal of radioactive waste, undertaken by the French National Radioactive Waste Management Agency (ANDRA). Due to its strong density and weak permeability, the formation of Callovo-Oxfordian argillite is chosen as one of possible geological barriers to radionuclides. The objective of the study to develop and validate a non linear homogenization approach of the mechanical behavior of Callovo-Oxfordian argillites. The material is modelled as a composite constituted of an elasto(visco)plastic clay matrix and of linear elastic or elastic damage inclusions. The macroscopic constitutive law is obtained by adapting the incremental method proposed by Hill. The derived model is first compared to Finite Element calculations on unit cell. It is then validated and applied for the prediction of the macroscopic stress-strain responses of the argillite at different geological depths. Finally, the micromechanical model is implemented in a commercial finite element code (Abaqus) for the simulation of a vertical shaft of the underground laboratory. This allows predicting the distribution of damage state and plastic strains and characterizing the excavation damage zone (EDZ). (author)

We present data from an observational cohort study on human immunodeficiency virus (HIV) prevention and control measures in prisons in Estonia to assess the potential for HIV transmission in this setting. HIV testing and retesting data from the Estonian prison health department were used to estimate HIV prevalence and incidence in prison. Since 2002, voluntary HIV counselling and testing has routinely been offered to all prisoners and has been part of the new prisoners health check. At the end of 2012, there were 3,289 prisoners in Estonia, including 170 women: 28.5% were drug users and 15.6% were infected with HIV. Of the HIV-positive inmates, 8.3% were newly diagnosed on prison entry. In 2012, 4,387 HIV tests (including retests) were performed in Estonian prisons. Among 1,756 initially HIV-negative prisoners who were in prison for more than one year and therefore tested for HIV twice within 12 months (at entry and annual testing), one new HIV infection was detected, an incidence of 0.067 per 100 person-years (95% confidence interval (CI): 0.025–5.572). This analysis indicates low risk of HIV transmission in Estonian prisons. Implementation of HIV management interventions could impact positively on the health of prisoners and the communities to which they return.

French radioactive waste disposal concept involves cementitious materials in a clayey host-rock. The presence of exothermic wastes in the storage cells may induce a temperature of about 70 Celsius degrees at the material interfaces. At present, experiment thermal conditions have been undertaken at about 20 C. degrees and studies at higher temperature are really scarce, especially experiments considering diffusion through the cement / clay interface. The still on-going study presented here is focusing on argillite / CEM-I interface. A one-year experiment under in situ conditions at the Tournemire experimental station (IRSN) was carried out and meanwhile, preliminary reactive transport modelling with HYTEC helped to understand the impact of a high temperature on the physico-chemical behaviour of cement / clay interface. The first results showed decalcification of cement and diffuse carbonation as well as a possible illite precipitation of clay-type phases. A C-S-H ribbon appeared at the interface between the two materials and a layer grew between the C-S-H ribbon and the cementitious material. This layer contained zeolites and behaved as a diffusive barrier. After one year of in situ interactions, the disturbance thickness was about 350 microns in CEM-I cement paste and about 100 microns in argillite. The modelling reproduced relatively well the experimentally observed processes but the extension of the disturbance is too wide and the zeolite layer is misplaced according to the experimental observations. This study highlights the lack of data at highest temperature on the reaction kinetics, diffusion coefficients but also on porosity variations. (authors)

Eesti autobiograafilise kirjutuse kujunemisest 18. sajandist Teise maailmasõjani. The Development of Estonian Autobiographical Writing from the 18th Century to the Second World War

Directory of Open Access Journals (Sweden)

Rutt Hinrikus

2012-04-01

Full Text Available In this article I examine the development of Estonian autobiographical writing from its first manifestations to published memoirs, and the development of life writing and its diversification. The beginnings of life writing can be traced back to Estonian folk song and Estonian incidental poetry. The Moravian Brethren movement in Estonia in the 18th century promoted the spread of canonical autobiography. The Moravian Brethren offered alternative opportunities for self-realisation for Estonians who were serfs, and were therefore popular with the people. The practice of the Moravian Brethren made use of retelling and writing about the life of the congregation members, which sometimes became suitable biographies in print, especially stories of awakening. Several manuscript biographies have survived from the Brethren times, such as the biographies of Mäletu Jaan and Mihkel Sarapuu. In addition to the history of the Moravian Brethren movement, these biographies give information about the educational situation and living conditions of the people of the time. The Estonian life writing tradition emerged within the reigning Baltic German cultural space thanks to the Estophiles among the Baltic Germans (J. H. Rosenplänter and the first Estonian men of letters; from the early 19th century we have the diary by Rosenplänter, an estophile pastor from Pärnu, and the diary by the Estonian poet, the then-student Kristjan Jaak Peterson, both in the Estonian language. Johann Voldemar Jannsen, the founder of Estonian-language journalism, kept a diary in the German language for a longer period of time; it was usual that the first Estonian intellectuals (Lilli Suburg, and others in the late 19th century wrote in German. Admittedly, the first Estonian-language life history was written by a forward-looking 19th century peasant named Märt Mitt (1833-1912, who was conscious of himself as a historical subject and gave his memoirs, begun in the 1880s, a memorable title

Acquisition of noun derivation in Estonian and Russian L1

Directory of Open Access Journals (Sweden)

Reili Argus

2018-04-01

Full Text Available Acquisition of derivation is not a well-studied area in first language research and a comparative approach to the acquisition of derivation in different languages doesn’t exist. There is no information on how a child acquires derivation in a language with a rich and regular system of derivational patterns, or in a language where derivation is productive, but the system of derivational patterns is opaque. According to general ideas of complexity in a language, the child should start to use simplex stems first and, only after that, complex ones, that is, complexity should increase in the course of acquisition. Our paper is intended to address these issues, based on longitudinal child data from typologically different languages, Estonian and Russian. The results revealed significant differences in the acquisition of noun derivation in the two languages under observation. The system of noun derivation is acquired at a faster pace in Russian, while Estonian children have far fewer noun derivatives in their speech and they use different derivation suffixes with less regularity. Even so, the so-called building block model may be applied for both languages only partially.

Az észt névtervezés az észt nyelvpolitikai modell tükrében [The name management in the mirror of the Estonian LPP-model

Directory of Open Access Journals (Sweden)

Pomozi, Péter

2016-12-01

Full Text Available The Estonian model of language planning and policy, which has been serving the development and protection of the Estonian language in its current form since 2004, is one of the most successful of such strategies in Europe. It owes it success to the broad social and scientific consensus reached in questions of language policy, regardless of changes in government. The Development Plan of the Estonian Language divides Estonian language planning and policy into three parts: status planning, corpus planning and prestige planning. Name management is a part of corpus planning, although certain aspects are also connected to legal and prestige planning. Name management strategies are present in all components of the Estonian model of language planning and policy, as linguistically appropriate name use is not only a socio-cultural, but economic question, as informative and easy to understand names contribute to measurable economic advantages. The paper mainly demonstrates the dilemmas and answers of Estonian name management through examples from personal name giving practices, but questions concerning the problems of name use in a multicultural environment and the difficulties of place name and firm name management are also discussed.

Fletcher, Amy L

2004-04-01

This case study of the Estonian Genome Project (EGP) analyses the Estonian policy decision to construct a national human gene bank. Drawing upon qualitative data from newspaper articles and public policy documents, it focuses on how proponents use discourse to link the EGP to the broader political goal of securing Estonia's position within the Western/European scientific and cultural space. This dominant narrative is then situated within the analytical notion of the "brand state", which raises potentially negative political consequences for this type of market-driven genomic research. Considered against the increasing number of countries engaging in gene bank and/or gene database projects, this analysis of Estonia elucidates issues that cross national boundaries, while also illuminating factors specific to this small, post-Soviet state as it enters the global biocybernetic economy.

Maarja Klaas

2015-06-01

Full Text Available This paper focuses on the meanings assigned to Tatar language among the Tatar diaspora in Estonia. According to interviews with Estonian Tatars as well as descriptions of field material from Tatarstan, language is an important aspect of Tatar ethnic identity. This paper will track common discourses about the Tatar language and the way it is connected to Tatar ethnic identity. Issues concerning Tatar language are used to demonstrate various ways of enacting Tatarness in Estonia. It is shown that Estonian Tatars worry about the vitality and purity of Tatar language, but for some, marginalization of dialects is also an issue. People categorized with the same identity labels by self and others can experience and enact their Tatarness in a variety of different ways.

Experimental study on poro-mechanical behavior of saturated Meuse-Haute/Marne argillite subjected to triaxial compression

International Nuclear Information System (INIS)

Hu, Dawei; Zhang, Fan; Xie, Shouyi; Shao, Jianfu

2012-01-01

Document available in extended abstract form only. Due to its low permeability (10 -18 to 10 -20 m 2 ), the Meuse-Haute/Marne argillite is chosen as the candidate host rock for the geological disposal of high-level radioactive waste by 'Agence Nationale de gestion des Dechets Radioactifs' (ANDRA). During the excavation of the underground tunnel in argillite formation, the Excavation Damaged Zone (EDZ) is expected to develop due to the stress redistribution during excavation and subsequent rock convergence. The nucleation and propagation of microcracks in EDZ can consequently affect the poro-mechanical behavior of the host rock. Therefore, it is of crucial importance to study the poro-mechanical behavior of Meuse-Haute/Marne argillite under the influence of stress induced microcracks. For this purpose, this paper presents the original experimental results of drained and undrained triaxial compression tests as well as evolution of Biot's coefficient during hydrostatic and deviatoric loading of saturated Meuse-Haute/Marne argillite. The size of samples used in the present work is 20x20 mm in order to reduce the saturating time. The axis of the cylindrical sample is perpendicular to the bedding planes. The test system is placed in an insulated room and a temperature control system is used to maintain a constant temperature of 20 ±0.2 C. The saturation condition is an important factor for the determination of the mechanical and poro-elastic properties of saturated argillite. Thus, for each sample, after putting into the triaxial cell, the confining pressure is loaded to 2 MPa and we inject distilled water both at the injection and outlet faces in order to insure the pore pressure at the two faces hold at 1 MPa. This procedure will be keep to 72 hours. Then, the pore pressure at the injection face is increased to 1.5 MPa, and we record the pore pressure at the outlet face. Once the pore pressure at the outlet face reaches the same value at injection face, the sample is

Experimental study of the anisotropic properties of argillite under moisture and mechanical loads

International Nuclear Information System (INIS)

Yang, D.S.; Chanchole, S.; Wang, L.L.; Bornert, M.; Gatmiri, B.

2012-01-01

Document available in extended abstract form only. Due to various factors, such as sedimentation, layered morphology of clay mineral, in-situ stress, etc., the behavior of argillite rocks is often anisotropic. In order to study the anisotropy of the Callovo-Oxfordian (COx) argillite considered as a possible host rock for high-level radioactive nuclear waste repository in France, a series of tests including uniaxial compression and dehydration and hydration at different constant applied stress levels, are carried out using a specific setup combining mechanical and moisture loading devices. During these hydro-mechanical tests, this specific setup can also continuously capture images of the sample surfaces to be subsequently analyzed using Digital Image Correlation techniques (DIC) in order to determine full-field strains. In this study, three sampling directions are used with the angle θ between the bedding plane and the cylindrical sample axis equal to 45 deg., 60 deg. and 90 deg.. To investigate the mechanical anisotropy, uniaxial compressive tests with mechanical loading and unloading cycles are performed on several different samples at the same moisture level. The results show that the mechanical parameters (apparent modulus, failure stress) depend on loading orientation relative to the stratification plane. For a given water content, the failure stress reaches maximum values for θ =90 deg. and minimum values for θ =45 deg.. To study the hydric anisotropy, dehydration and hydration tests under stress-free conditions are performed on two cylindrical samples (θ=90 deg. and θ=60 deg.). Three cycles of hydration and dehydration are carried out by varying the relative humidity between 40% and 95%. The sample weight, the deformation measured by strain gages and the relative humidity are continuously recorded during the test by means of another specific setup described in [Pham et al., 2007]. Fig.1a illustrates the evolution of the strains of the sample EST28030-No

Isamaalaulud ja okupatsioonirežiim – nostalgia, utoopia ja reaalsus. Estonian Patriotic Songs and the Occupational Regime – Nostalgia, Utopia and Reality

Directory of Open Access Journals (Sweden)

Kanni Labi

2012-04-01

Full Text Available Estonian knowledge of history emanates from the fact that constituting an independent nation has for the most part been nothing but a utopia, and was a reality for a relatively short time. When it comes to selfidentification though, the expression ’a singing people’ is often used by the Estonians to describe themselves. Nostalgia for freedom is reflected in the Estonian culture of almost all periods and is carried on by the singing tradition, where patriotic songs emerge independent of different musical tastes within a particular generation and form an important part of a common Estonian repertoire. Patriotic songs occupy a central place in several fields of Estonian culture: besides music culture also in popular culture,and literary history – the works of poetry which have gained the most popularity are those which when put to music have been the most widely spread among the people. The main part of the most popular Estonian patriotic songs are choral songs from the national awakening at the end of the 19th century. Despite the national programmes aiming to wipe out ‘bourgeois nationalism’, they were sung at the song festivals in the Soviet era and were published in song books, expressing the people’s nostalgia for freedom lost. After the end of the Second World War, there was an attempt at launching a kind of patriotic new creation, where patriotism was merged with Soviet pathos; the aim was to show that the people’s utopia was in fact communism, but not a single one of those songs made it into the people’s common repertoire. Only the patriotic songs composed in the 1980s during the so-called new national awakening reached a popularity comparable to that of the old songs. The discourse on ’Estonianness’ and the shaping of a matching repertoire under imperial Russian rule took place under very different circumstances than its preservation and development in the second half of the 20th century under Soviet occupation, but

Osteogenesis imperfecta (OI) is a rare bone disorder. In 90% of cases, OI is caused by mutations in the COL1A1/2 genes, which code procollagen α1 and α2 chains. The main aim of the current research was to identify the mutational spectrum of COL1A1/2 genes in Estonian patients. The small population size of Estonia provides a unique chance to explore the collagen I mutational profile of 100% of OI families in the country. We performed mutational analysis of peripheral blood gDNA of 30 unrelated Estonian OI patients using Sanger sequencing of COL1A1 and COL1A2 genes, including all intron-exon junctions and 5'UTR and 3'UTR regions, to identify causative OI mutations. We identified COL1A1/2 mutations in 86.67% of patients (26/30). 76.92% of discovered mutations were located in the COL1A1 (n = 20) and 23.08% in the COL1A2 (n = 6) gene. Half of the COL1A1/2 mutations appeared to be novel. The percentage of quantitative COL1A1/2 mutations was 69.23%. Glycine substitution with serine was the most prevalent among missense mutations. All qualitative mutations were situated in the chain domain of pro-α1/2 chains. Our study shows that among the Estonian OI population, the range of collagen I mutations is quite high, which agrees with other described OI cohorts of Northern Europe. The Estonian OI cohort differs due to the high number of quantitative variants and simple missense variants, which are mostly Gly to Ser substitutions and do not extend the chain domain of COL1A1/2 products.

One purpose of this project was the establishment of a radon monitoring programme inside the state environmental monitoring programme. Another purpose was to investigate regions, expected to have high radon levels indoors. A new method for the long-term measurement of indoor radon was established and the staff for these measurements was trained. The results of the measurement can be used by Estonian decision-makers to work out rules and standards. There is no legislative act in the field of radiation in Estonian at this time. To summarize the results of the measurements we can say that indoor radon concentrations vary by region. The radon investigations must be continued to identify the risk areas and types of housing construction. The results of the state radon monitoring are provided to the municipalities, who advice the owners of planned new houses to select the right construction for the house. A new project will follow with an investigation of radon in randomly selected dwellings, training and equipment for radon measurement in soil, and general advice with regard to radon, as well as assistance in preparing information about radon. 7 refs, 5 figs

by scanning electron microscope observations to identify the related mineral alterations. Significant changes were observed in the mineral compositions of the whole rocks and in the chemical and Sr-isotopic composition of the leachates when the storage duration in ambient temperature or during heating increased. The main variations were: (1) a significant decrease of the element contents in the leachates, meaning in turn the decrease of the released elements from minerals constitutive of the rocks when duration increased. This decrease was rapid in the COX argillite, after storage at ambient temperature and exposition at 95 deg. C, and was followed by a progressive trend to a new stable state. In the Opalinus Clays, the decrease was progressive and accompanied by a decrease of the 87 Sr/ 86 Sr ratio of the leachates, but no trend towards a new stable state could be observed; (2) an alteration of pyrite followed by a precipitation of Ca-sulfate, which appeared to start in the core of the crystals towards the rims; it also lead to the replacement of Fe-sulfides by Fe-oxides; (3) a probable precipitation of new mineral phases in the rocks, such as Fe-oxy-hydroxides and/or jarosite that could not be visualized by electron microscopic observation because of their very limited amount and very small grain size. All the modifications call for an oxidation of pyrite probably combined with dehydration of the rock, inducing changes in the pH conditions of interstitial fluids. They probably also induced an oxidation of the organic matter, which was enhanced by temperature increase. The study allowed identification of the changes occurring in the rocks exposed to atmosphere that are recorded in the mineralogical feature and in the chemical and Sr isotopic composition of their soluble mineral phases. Leaching appears to be an appropriate procedure for identifying and quantifying such reactions that are explained by oxidation and dehydration processes of the mineral and organic

Re-conceptualizing mother tongue tuition of Estonian abroad as a transnational phenomenon

Full Text Available The governmental initiative called the Compatriots Programme, which supports language tuition in Estonian schools and societies abroad, reveals an increased interest in developing intergenerational language transmission in the growing Estonian diaspora. This transnational language political activity signals a new era in language policy, where nation states are increasingly decentralized by migration. The evaluation of the program furthermore reveals that organizing such schools requires a willingness to take language political agency, typically conducted by well-educated and well-integrated resourceful transnational multilingual parents. The present article outlines the results of an ethnographic study of the process of establishing the Estonian School in Copenhagen. This step has demanded a change in the mindset still prevailing in Estonia that language political activities, such as planning language acquisition, are solely the responsibility of the state. Since the prevailing language ideology in Denmark is not favorable towards multilingualism in migrant languages, intergenerational language transmission furthermore presupposes a feeling of ownership of the language and high language self-esteem.

Full Text Available Changes in the Estonian National Museum from 1909 to the presentThe Estonian National Museum was founded in Tartu in 1909 as part of the national movement. With its activities and connections in society, the ENM helped create Estonian society, the nation’s collective memory and identity.The ENM has always been – despite the changing locations, names, and content – one of the symbols of national identity. But at the same time, ENM has never had its own building designed specially for the museum’s purposes.Since 1909 there have been several attempts to establish a home for the ENM. At first (1909–1923, Estonian society wanted to establish the museum in the center of Tartu. The museum was intended to become a key institution of the growing nation and establishing the nation’s identity.At last in 1923 the ENM secured the Raadi manor, outside the center of the city, in a beautiful park, near the lake with its boats and water attractions. In this manor the first permanent exhibition of mainly 19th century Estonian peasant life was compiled, and the ENM operated in the Raadi manor from 1923–1940 as the “Estonian’s own museum” The years of alternating occupations, World War II, and political terror damaged and destroyed the whole society. The Raadi manor was destroyed in the war too, and the ENM itself was divided into two parts – the State Ethnographic Museum and the State Literary Museum. The collections of the ENM were given to Tallinn and to many different places inside and outside Tartu. Then began “the period of temporary location” that continues today. The museum is located in several places in the city of Tartu.In 1988, the prior name of the State Ethnographic Museum – the Estonian National Museum – was reinstated. Since the 1990s there have been many attempts to secure a special building for the ENM. Now, at last, as a result of serious economic pressure, we are closer to this goal than ever.

The storage in deep geological formation is one of the solutions retained by France for the management of highly long life radioactive waste. The retained host rock is a clay-stone named East argillite located in the departments of Meuse and Haute-Marne. A thermodynamic formulation is used to propose a rheological model, which reproduces the mechanical behavior of clay-stones. Initially, an anisotropic damage plastic model was formulated in order to describe material degradations. Then, the damage plastic model is reformulated in order to taken into account the damage influence on the hydraulic behavior of porous material. The numerical simulations correctly reproduce the mechanical behavior of East Argillites but also the anisotropy of the hydraulic behavior introduced by the damage effect. (author)

Vene kirjandus venestusaja eesti koolides. Russian Literature in the Estonian Schools of the Russification Era

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

How to Improve the Supportive Role of Estonian Innovation System toward Launching New Products by High Technology Companies?

Directory of Open Access Journals (Sweden)

Liisi Sepp

2013-01-01

Full Text Available The purpose of the study is to evaluate how supportive is Estonian national innovation system toward the launching of new innovative products by high technology firms. The article intends to combine two broad areas of research – national innovation system approach and the different models of the new product launching. Based on the literature review and in-depth analysis of three case studies of Estonian high-tech company’s major barriers as well success factors of highly innovative product launches were identified. The barriers of the new product launching were linked with the systemic failures of the national innovation system. The most relevant failures of Estonian national innovation system inhibiting the new product development are capability and networking failures. The sources of innovation of high-technology firms are too narrow, linkages with domestic firms and higher education institutions as well with foreign firms are poorly developed. High-tech firms have also serious capacity problems due to the extremely weak support mechanism by national innovation system on the seed funding stage of product development and prototype building stage as well. Paper argues that resources needed for the innovation should not be looked too narrowly following linear innovation model approach. Instead interactive approach is needed, which combines capability building, network development, interactive learning with direct investments into fundamental research.

Full Text Available Recession has sharply erected the question of tax burden and the optimal proportion of different kinds of taxes among the incomes of the budget. Indirect taxes and consumption taxes, which proportion is different according to different methodologies, dominate in Estonian state budget. The buoyancy of a tax system based on taxes of that kind is especially weak during the recession. The purpose of Estonian government’s economic policy during the highest peak of crisis was to keep the budget in balance. Instead of recovering economy the taxes were arisen and costs were reduced. The results of such a policy aren’t still clear. Difficulties concerning the incomes of budget have arisen the necessity for lifting taxes, which is possible as the tax burden is low now. But a sharp question of the optimal level of taxes is going to be raised. A formula for indirect tax optimum according to Ramsey taxes and Slutski decomposition has been proposed in the article

Geological repository layout for radioactive high level long lived waste in argillite

International Nuclear Information System (INIS)

Gaussen, JL

2006-01-01

In the framework of the 1991 French radioactive waste act, ANDRA has studied the feasibility of a geological repository in the argillite layer of the Bure site for high level long lived waste. This presentation is focussed on the underground facilities which constitute the specific component of this project. The preliminary underground layout which has been elaborated is based on four categories of data: - the waste characteristics and inventory; - the geological properties of the host argillite; - the long term performance objectives of the repository; - the specifications in terms of operation and reversibility. The underground facilities consist of two types of works: the access works (shafts and drifts) and the disposal cells. The function of the access works is to permit the implementation of two concurrent activities: the nuclear operations (transfer and emplacement of the disposal packages into the disposal cells) and the construction of the next disposal cells. The design of the drifts network which matches up to this function is also influenced by two other specifications: the minimization of the drift dimensions in order to limit their influence on the integrity of the geological formation and the necessity of a safe ventilation in case of fire. The resulting layout is a network of 4 parallel drifts (2 of them being dedicated to the operation, the other two being dedicated to the construction activities). The average diameter of these access drifts is 7 meters. The link between the surface and the underground is ensured by 4 shafts. The most important function of the disposal cells is to contribute to the long term performance of the repository. In this regard, the thermal and geotechnical considerations play an important role. The B wastes (intermediate level wastes) are not (or not very) exothermic. Consequently, the design of their disposal cells result mainly from geotechnical considerations. The disposal packages (made of concrete) are piled up in

Interpreting strain measurements when drilling anisotropic rocks: return of experience from using CSIRO cells in Tournemire argillite

International Nuclear Information System (INIS)

Ben Ouanas, Abdelmonem

2010-01-01

In Geomechanics, determining the state of stress and the rheology of rock massif can be obtained by measuring the strain response of the ground under the effect of a known stress. A method among others is to use a cell integrated (with strain gauges oriented in different directions) installed in a borehole and secured to the mass through an epoxy glue. This measurement is used, notably, to determine the stress state in situ by the 'overcoring' method and the elastic parameters of the rock from the 'biaxial' test. Between November 2005 and January 2006, a geomechanical testing campaign was conducted in the argillaceous formation of the Tournemire experimental site (Aveyron, France) using CSIRO Hi cells. The strain measurements obtained during overcoring and biaxial tests have shown unusual phenomena, which have made difficult the determination of anisotropic elastic parameters of the rock and the access to the site stress. Therefore, through researches for explanations of the origin of these phenomena, this thesis aimed to improve and contribute to the understanding of the Tournemire argillite behaviour and to upgrade the measurement protocol as well as the interpretation of cells CSIRO's strain. The approach was, firstly, to issue a number of hypotheses to explain certain phenomena observed in literature. In a second step, these hypotheses were tested through analytical and numerical modelling of the biaxial and overcoring tests then through the realization of new experiments in situ within laboratory on argillite, and also on materials tests (cement, sample of glue). It is concluded that the unusual phenomena observed are essentially the result of the conditions for implementing in situ CSIRO's cell. The study particularly focused on the artefacts induced by the visco-plastic behaviour of the epoxy glue when it is incompletely polymerised. The role of damage on the rock generated by drilling operations is also discussed. Some practical recommendations for

Full Text Available Seminatural grasslands i.e. the floodplain meadows, seashore meadows, wooded meadows, dry meadows, wooded pastures are the very traditional part of Estonian landscapes, which play an important role in the appearance of the landscape in general and also serve as an important habitat for many plant and animal species. In order to preserve the seminatural grasslands continuous annual mowing and/or pasturing is needed. This activity is not economically profitable and needs subsidizing. The authors of the work raise a hypothesis that the Estonian seminatural grasslands could be viewed as a valuable non-market environmental good for which a significant public demand exists. In order to find out the non-market value of the seminatural grasslands a contingent valuation study was carried out among the Estonian working-age population (size of the sample 1061 individuals. The average individual willingness to pay was 11.3 euros. During the study, the authors constructed the total demand function and discovered that the total annual demand for seminatural grasslands was 17.9 million euros.

To study the long-term mental health consequences of the 1986 Chernobyl nuclear accident among cleanup workers from Estonia. In 2010, 614 Estonian Chernobyl cleanup workers and 706 geographically and age-matched population-based controls completed a mail survey that included self-rated health, the Posttraumatic Stress Disorder Checklist (PCL), alcohol symptoms (AUDIT), and scales measuring depressive, anxiety, agoraphobia, fatigue, insomnia, and somatization symptoms. Respondents were dichotomized into high (top quartile) and low symptom groups on each measure. Logistic regression analysis detected significant differences between cleanup workers and controls on all measures even after adjustment for ethnicity, education, marital status, and employment status. The strongest difference was found for somatization, with cleanup workers being three times more likely than controls to score in the top quartile (OR = 3.28, 95% CI 2.39-4.52), whereas for alcohol problems the difference was half as large (OR = 1.52, 95% CI 1.16-1.99). Among cleanup workers, arrival at Chernobyl in 1986 (vs. later) was associated with sleep problems, somatization, and symptoms of agoraphobia. The toll of cleanup work was evident 24 years after the Chernobyl accident among Estonian cleanup workers indicating the need for focused mental health interventions.

2013-06-01

Full Text Available The article describes the conception and editing process of an anthology of Johannes Becher’s poems (Unistades täiusest, 1962 in Estonian, and discusses its status in the Soviet and contemporary literary canon. The work on the Becher anthology was led by an already outstanding literary scholar Nigol Andresen and a young poet and translator Ain Kaalep, who later became one of the most prolific and wellknown poetry translators in Estonia. An important part was also played by another poet-translator, August Sang, who already had achieved such a standing in the Estonian literary field. Several other translators contributed to the anthology, making it a common project for intellectuals otherwise very differently positioned vis-à-vis the Soviet political authorities and cultural agendas. Becher’s work was strongly promoted by these instances, but his poetry was also read with genuine enthusiasm by the main contributors to the anthology (whose own poetry has certain parallels to some aspects of Becher’s, as well as the general public, at that time. After the fall of the Soviet regime it has been forgotten, mostly for the same contextual reasons that once granted its success. The case of his poetry in Estonian explores the question of this new invisibility of now politically irrelevant, but still voluminous and aesthetically intriguing literary works in the post-Soviet canon.

Full Text Available In this paper, we compare the use and functions of definite and indefinite article-like determiners in Estonian and Finnish. Our main aim is to explore whether the factors that explain the choice of particular determiner forms are similar in Estonian and Finnish. We use a picture-sequence based elicitation experiment to collect spoken narratives from adult native speakers of Estonian and Finnish, and apply non-parametric tree and forest models to analyze the data. Our findings indicate that number of mention and animacy are important predictor variables in both languages, but their exact effect is divergent. We also find that in Finnish, case of the determiner NP proves to be an important factor, while in Estonian, syntactic role of the NP explains some aspects of determiner form choice. Nevertheless, the overall usage frequency of determiners is modest in the Estonian and Finnish data, and the process of grammaticalizing articles is only in initial stages in both languages. *** Artikliga, artiklita?

Nearby such a site, some microorganisms may influence the mobility of radionuclides coming from the waste canisters. This work consisted in looking for autochthonous microorganisms in the Opalinus clay formation from Mont Terri (Switzerland) and in the Callovo-Oxfordian argillite from Meuse/Haute-Marne (France). Microbial Investigations in these unknown unperturbed environments suggested very low microbial densities in the clayey sediments. However, new bacterial species could be isolated from those samples. In addition, a part of the allochthonous population, which has been introduced by air and human activity, could be identified in the Meuse/Haute-Marne underground research laboratory. (author)

First, I give an overview of the basic positions of the Young Estonians’ literary discourse, the main shapers of which were Friedebert Tuglas, Gustav Suits, later on Johannes Semper as well. Next, I present the basic principles of three Estonian literary discourses from the beginning of the 20th century, which were also important to the Young Estonians: nationalist-naturalistic (close-to-life; socialist/ class-based, and 20th century modernist. The Young Estonians began as nationalists and/or socialists. During the formation of Young Estonia’s discourse at the end of the first and beginning of the second decade of the 20th century, 20th century modernism began, which the Young Estonians regarded first and foremost with irony. The Young Estonians’ literary discourse is a mixture of aestheticism, decadence, symbolism, romanticism, and classicism. The point of departure for the Young Estonian approach to literature was eurocentrism. They took a superior and negative view of existing Estonian literature, which they regarded as having fallen drastically behind Europe. Since it was unable to build on its own foundation, it had to borrow from Europe. The discourse’s understandings of cultural values – theory, reading, knowledge, ready-made culture, derive from the centrality of the dynamic of borrowing. New culture could be created freely, without the support of previous local tradition; it was to be an elite culture, while the writer remained an individualist. Literature was to follow the principle of art for art’s sake; aesthetics and the form of the work of art were basic criteria. The formal ideals of the work of art were classicist: unity, integrity (wholeness, harmony, order, logic, etc. Thirdly, I outline the

A countrywide survey of radon concentrations in Estonian dwellings was carried out during the period 1998-2001. The survey formed a part of the cooperation program on radiation protection between the Estonian Radiation Protection (Kiirguskeskus) Centre and the Swedish Radiation Protection Authority (SSI). The survey included measurements in a number of dwellings representative for Estonia in detached houses and multifamily buildings (only dwellings on the bottom floor were included in the survey). Altogether, radon concentrations were measured in 515 dwellings, a number large enough to be statistically significant. All measurements were made with alphatrack film detectors of the same type that SSI uses in Sweden. The measurements were made during a 2-3 month period during the winter half-year. Two detectors were used in each dwelling. In Estonia there are 0.17 million dwellings in detached houses and 0.45 million in multi apartment buildings. Of the 1.26 million inhabitants in Estonia. 0.36 million live in detached houses and 0.90 million in multi apartment buildings. Most of the latter were built during the Soviet occupation. Of the dwellings in multifamily buildings 30 % are assumed to be situated on the first floor. The mean radon concentration in dwellings in detached hoses, according to the survey results, is 103 Bq/m{sup 3}, in dwellings on the bottom floor in multi apartment buildings it is 78 Bq/m{sup 3}. In 1% of the dwellings the radon concentration exceeded 400 Bq/m{sup 3}. The highest radon concentration found in the study was 1040 Bq/m{sup 3}. Based on the assumption that the average radon concentration in the dwellings in multi-apartment buildings that are not situated on the bottom floor is 30 Bq/m{sup 3}, and that these dwellings constitute 70% of all dwellings in multi apartment buildings, the mean radon concentration in dwellings in multi apartment buildings is calculated to be 44 Bq/m{sup 3}. The mean value for all Estonia dwellings is calculated

Full Text Available According to the long-standing periodisation of Estonian literary history, the Estonian National Awakening that started in the mid-19th century was followed by a period of lesser creativity and originality, which ended only with the breakthrough of the modernist Young Estonia group in 1905. In the canon of Estonian literature, Juhan Kunder (1852–1888, today known primarily for his fairy tales, one play and lyrics of one song, is placed in this intermediate period. This article first introduces the significance of Kunder in his time. He was a popular writer and a wellknown pedagogue, and a younger contemporary of the great figures of the National Awakening. As a critic, magazine editor and literary historian, his most important contribution to literary history was in the development of literary thought. It seems that several precedents that have been attributed to the Young Estonia group, e.g., valuing originality, writing well-argued criticism, etc., actually originated from an earlier period. Based on these observations, the author of this article believes that the current structure of Estonian literary history is not adequately justified, and she points out a semantic shift in the terms in use. It is true that Kunder was largely an epigone of his predecessors, but in the positive sense of the term, meaning that he continued their mission. Similarly, Kunder’s predecessor, the ‘first Young Estonian’ Kreutzwald, and a representative of his 20th-century successors, Friedebert Tuglas, were also epigones. During the period of Russification that started during his era, Kunder’s attitudes could be considered progressive. Kunder was also a 19th-century contemporary of the Young Estonia group and a true Young Estonian in the original sense of the term which emerged in this period: a Young Estonian introduced new initiatives and was a leader of the national movement. Epigonism and membership in Young Estonia can be seen as the keys to cultural

Rahvusliku ajaloo tõlgendusi eesti draamas ja teatris 1970.–1980. aastatel. Interpretations of National History in Estonian Drama and Theatre in the 1970s–1980s

Full Text Available According to theatre scholar Freddie Rokem, theatre portraying or performing historical events is seeking to overcome both the separation and the exclusion from the past, as well as ’striving to create a community where the events from this past will matter again’. This article covers the topic of interpretations of national history in Estonian theatre and in original dramaturgy during the Soviet era, with the focus on aspects like national self-reflection and the relationship to the common past. The main focus is on the 1970s, with examples from Rein Saluri’s, Mati Unt’s and Jaan Kaplinski’s drama productions. During the period in question, re-tellings of national history on Estonian theatre stages were clothed in metaphors, allusions and secret codes – Aesopian language. Within the Soviet cultural context, I analyse if and to what extent theatre of the time displayed resistance, political theatre or social allegory. Theatre was also connected with the principle of playing or playfulness, which on one hand indicates national resistance, national endurance, and a certain survival strategy, but on the other hand indicates the Estonian as being an involuntary homo ludens – the Playing Man, who through various enforced roles is trying to adjust to the whirlwinds of history. Saluri’s first play, the intellectual drama Külalised (The Guests, opens with an allusion to a drama classic the world over, William Shakespeare’s Hamlet, adding a powerful national-symbolic background to the play. The role-play which permeates and structures the play (The Host–The Guest however, displays allegorical references to changes in the status and self-image of Estonians. In Unt’s play Peaproov (Dress Rehearsal, the principle of playing/acting sheds ironic light on the makers of an historical film and their readiness to create superficially flashy interpretations at any cost: this take acts as an estranging and generalising reflection in a context

The Dialogue with Hamlet: Paul-Eerik Rummo’s “Hamlet’s Songs” as an Example of the Existential Paradigm in Estonian Culture

Directory of Open Access Journals (Sweden)

Anneli Mihkelev

2013-06-01

Full Text Available The article demonstrates different meanings of the motif of Hamlet in the Estonian culture. Hamlet as a literary figure has been very important and influential, a symbol of will and a fighter in a hopeless situation. Paul-Eerik Rummo’s poem “Hamlet’s Songs” (1964 forms the centre around which revolve not only written texts but also many such cultural texts as theatre performances and music, all connected by allusions to Hamlet. Rummo’s poem is one of the most innovative poems from the 1960s in Estonian literature. The generation of the 1960s was influenced by several important contemporary theories, including existentialism. Many young writers systematically undermined the Soviet regime in their works. The use of the motif of Hamlet reveals a similarity between the existential and romantic rebellions. Rummo’s dialogue with Hamlet in his poem expresses optimism in a hopeless situation in a way different from Shakespeare’s.

Full Text Available Recession has sharply erected the question of tax burden and the optimal proportion of different kinds of taxes among the incomes of the budget. Indirect taxes and consumption taxes, which proportion is different according to different methodologies, dominate in Estonian state budget. The buoyancy of a tax system based on taxes of that kind is especially weak during the recession. Difficulties concerning the incomes of budget have arisen the necessity for lifting taxes, which is possible as the tax burden is low now. But a sharp question of the optimal level of taxes is going to be raised. A formula for indirect tax optimum according to Ramsey taxes and Slutski decomposition has been proposed in the article.

2014-10-01

Full Text Available The article concerns itself with the figure of the teacher in Estonian society. We do not concentrate on the educational system as a whole, but on one specific and crucial element in this apparatus - the teacher. We begin by offering a brief historical overview of the conditions of pedagogues in the 20th century before moving on to describe the adoption of neo-liberal free market policies since the 1990s and the effects these policies had and still have on education. Our main concern is to understand the teacher as an actor in power relations; to achieve this understanding we have selected as our examples 1 surveillance techniques in school environment that have direct relations to the state and the market; and 2 the 2012 educational workers' strike that made it quite clear that the teachers have been fixed to a position of wage workers. The overall and more abstract aim of the paper is to think about the social role of the teacher in Estonia.

Disposal of high-level nuclear waste in a geological repository requires analysis of heat distribution as a result of decay heat. Such an analysis supports design of repository layout to define repository footprint as well as provide information of importance to overall design. The analysis is also used in the study of potential migration of radionuclides to the accessible environment. In this study, thermal analysis for high-level waste and spent nuclear fuel in a generic repository in argillite host rock is presented. The thermal analysis utilized both semi-analytical and numerical modeling in the near field of a repository. The semi-analytical method looks at heat transport by conduction in the repository and surroundings. The results of the simulation method are temperature histories at selected radial distances from the waste package. A 3-D thermal-hydrologic numerical model was also conducted to study fluid and heat distribution in the near field. The thermal analysis assumed a generic geological repository at 500 m depth. For the semi-analytical method, a backfilled closed repository was assumed with basic design and material properties. For the thermal-hydrologic numerical method, a repository layout with disposal in horizontal boreholes was assumed. The 3-D modeling domain covers a limited portion of the repository footprint to enable a detailed thermal analysis. A highly refined unstructured mesh was used with increased discretization near heat sources and at intersections of different materials. All simulations considered different parameter values for properties of components of the engineered barrier system (i.e. buffer, disturbed rock zone and the host rock), and different surface storage times. Results of the different modeling cases are presented and include temperature and fluid flow profiles in the near field at different simulation times.

Full Text Available The article investigates lexical collocations encountered in English as a Foreign Language (EFL instruction in Estonian upper secondary schools. This is achieved through a statistical analysis of collocations featuring in three coursebooks where the collocations found are analysed in terms of their type, frequency and usefulness index by studying them through an online language corpus (Collins Wordbanks Online. The coursebooks are systematically compared and contrasted relying upon the data gathered. The results of the study reveal that the frequency and range of lexical collocations in a language corpus have not been regarded as an essential criterion for their selection and practice by any of the coursebook authors under discussion.

Vitality of the Estonian forests (results of the inventory and research)

Factors affecting Estonian forests are: The environmental, specially atmospheric pollution, - the foundation of new forests as monoculture on unsuitable locations, - mechanical damages by unsuitable forest machinery, - unfavourable water conditions, - Heterobasidion or Armillaria rot roots. Local damages in consequence of air pollutants are distributed in environments of Tallinn, Kivioli, Kohtla-Jaerve and the thermal power stations (Narva), where the SO 2 -content in the air is on the average higher than 50 (80) μg/m 3 . Pine forests on dry sand soils (600 ha damaged in 1989) and the older spruce forests show the new type of forest decline. High Al-ion concentration, disturbances of the Ca-Mg-metabolism, an extreme nutrient deficit, (specially N-deficit) and periodical water deficit as well as pathogenic fungi are damaging the trees. Spruces show nonspecific defoliation, needle necrosis, needlefall, occurence of fungal diseases. More damaged are the spruce forests in regions with basic precipitations and high sulphur-deposition.

To examine factors associated with early sexual intercourse among 15 to 16-year-old adolescents by gender. The data were collected from a random sample of Estonian basic schools' ninth grade pupils in 1999 using self-completed questionnaires. A multivariate logistic regression analysis for boys and girls was used to test for associations between sexual intercourse, and personal gender role-related attitudes, attitudes towards sexual intercourse, pubertal timing, smoking status and experience of drunkenness. Of the respondents, 14.6% of boys and 13.1% of girls had experienced sexual intercourse. Traditional gender role-related attitudes were associated with sexual intercourse among girls, but not among boys. Smoking and experience of drunkenness was strongly associated with sexual intercourse for both genders. Gender differences in the association between gender role-related attitudes and early sexual intercourse were observed among 15 to 16-year-olds in Estonia. Smoking and experience of drunkenness were strongly related to sexual intercourse for both genders.

MODELLING DICLOFENAC AND IBUPROFEN RESIDUES IN MAJOR ESTONIAN SEASIDE CITIES

Full Text Available A theoretical model was developed to model the fate of two common pharmaceutical residues: diclofenac and ibuprofen in eight Estonian seaside cities that discharge their wastewaters directly into the Baltic Sea. The consumption rates of the active ingredients of diclofenac and ibuprofen from 2006-2014 were analysed. A decrease of 19.9% for diclofenac consumption and an increase of 14.1% for ibuprofen were found. The fate of diclofenac and ibuprofen were modelled by considering the human metabolism removal rate for pharmaceuticals, the removal rate of diclofenac and ibuprofen in activated sludge wastewater treatment plants (WWTP and annual flow rates. An average decrease from 1 to 0.8 µg/l (decrease of 20% for diclofenac and an increase from 11.4 to 13.4 µg/l (increase of 14.9% for ibuprofen for the concentration in the effluents of the WWTP were modelled. The model gives us a good overview about the theoretical concentrations of pharmaceutical residues in the environment and is helpful for evaluating environmental impacts.

Full Text Available The laser-induced breakdown spectroscopy (LIBS combined with multivariate regression analysis of measured data were utilised for determination of the heating value and the chemical composition of pellets made from Estonian oil shale samples with different heating values. The study is the first where the oil shale heating value is determined on the basis of LIBS spectra. The method for selecting the optimal number of spectral lines for ordinary multivariate least squares regression model is presented. The correlation coefficient between the heating value predicted by the regression model, and that measured by calorimetric bomb, was R2=0.98. The standard deviation of prediction was 0.24 MJ/kg. Concentrations of oil shale components predicted by the regression model were compared with those measured by ordinary methods.

Small scale heater tests in argillite of the Eleana Formation at the Nevada Test Site

Near-surface heater tests were run in the Eleana Formation at the Nevada Test Site, in an effort to evaluate argillaceous rock for nuclear waste storage. The main test, which employed a full-scale heater with a thermal output approximating commercial borosilicate waste, was designed to operate for several months. Two smaller, scaled tests were run prior to the full-scale test. This report develops the thermal scaling laws, describes the pretest thermal and thermomechanical analysis conducted for these two tests, and discusses the material properties data used in the analyses. In the first test, scaled to a large heater of 3.5 kW power, computed heater temperatures were within 7% of measured values for the entire 96-hour test run. The second test, scaled to a large heater having 5.0 kW power, experienced periodic water in-flow onto the heater, which tended to damp the temperature. For the second test, the computed temperatures were within 7% of measured for the first 20 hours. After this time, the water effect became significant and the measured temperatures were 15 to 20% below those predicted. On the second test, rock surface spallation was noted in the bore hole above the heater, as predicted. The scaled tests indicated that in-situ argillite would not undergo major thermostructural failure during the follow-on, 3.5 kW, full-scale test. 24 figures, 6 tables

Change in medical plant use in Estonian ethnomedicine: a historical comparison between 1888 and 1994.

Science.gov (United States)

Sõukand, Renata; Kalle, Raivo

2011-05-17

The aim of this paper is to compare the changes in the utilization of species from various hemeroby categories (indicating the degree of sensitivity of the plant to human impact) using historical data concerning the years 1888-1994. The authors digitised 8808 handwritten reports, reflecting local ethnopharmacological knowledge from 8 selected collections from the Estonian Folklore Archives of the Estonian Literary Museum. They were semi-quantitatively analyzed according to the sensitivity to human impact of 540 taxa that could possibly be related to the plant vernacular names given in the reports. Although in different periods of time the number of ethnopharmacologically used plants has changed, the proportion of plants utilized from each group has remained relatively same, consisting on average of: 23% anthropophytes, 42% apophytes, 32% hemeradiaphores and 3% hemerophobes. Comparison of the application of the most used plants revealed considerable changes of plant utilization, in which the varied use of the most popular anthropophytes increased and the applied scope of the most popular hemeradiaphores and hemerophobes decreased almost by twofold in one century. Case studies on seven taxa are presented, of them, use of Allium sativum L., Aesculus hippocastanum L. and Mentha xpiperita L. increased, whereas the use of Hordeum L., Orchidaceae, Paris quadrifolia L. and Briza media L. decreased greatly. This research contributes to the better understanding of the cognitive and human ecological concepts underlying the use of medicinal plants in Estonia. Strong increase in the ethnomedical utilization of plants depending on human influence, and a decrease in the use of taxa that do not prefer human activities indicates that, despite some of the population still have access to natural resources and diverse knowledge of the medical use of plants, the majority relies on a very narrow selection and a rather restricted herbal landscape.

Chernobyl is still haunting us. Radionuclides in Estonian mushrooms

International Nuclear Information System (INIS)

Martin, J.; Vilde, R.; Martin, L.; Aaspollu, J.; Tekko, S.

1993-01-01

The disaster that happened at the Chernobyl nuclear power station in 1986 caused a sharp rise in radioactive pollution over an extensive area in the region of the Baltic Sea. To estimate the distribution and the concentration of Cs-137 and Sr-90 in Estonian ecosystems, samples of mushrooms, mosses, lichens and the upper horizons of soil were gathered from 63 test sites during 1991. We were particularly interested in the amounts of radionuclides in mushrooms because these are used as food by people. Dangerously high radionuclide concentrations were found in mushrooms gathered in North-East Estonia. Heightened concentrations were registered here and there all over the territory of Estonia, especially in mushrooms gathered in Central and South-Western Estonia. The Cs-137 content in mushrooms depends on its content in other components of the ecosystems, first and foremost on the concentrations of radiocaesium in mosses and litter, which, therefore, can be used as indicators in prognostication the radioactive pollution of mushrooms in a certain region. As Cs-137 migrates between various ecosystem components, it is necessary to check the radioactivity of the forest products used for food for still a number of years to come. The Sr-90 level was low in all the ecosystem components examined. (author). 3 figs., 10 refs

Kolm Eesti Robinsoni: Daniel Defoe romaan eesti tõlkes / Three Estonian Robinsons: Daniel Defoe’s Novel in Estonian Translation

Directory of Open Access Journals (Sweden)

Ene-Reet Soovik

2012-06-01

Full Text Available The article discusses three Estonian translations of Daniel Defoe’s Robinson Crusoe into Estonian with the focus on the completeness of the translated texts and the characterisation given to these in paratextual information. While there are several translations and versions of the tex t available in E stonian that have either used a mediating language or do not proceed directly from Defoe’s novel, three editions explicitly list Defoe’s English-language Robinson Crusoe as their source text. These are Rudolf Sirge’s translation from 1950 and two editions translated by Valter Rummel that appeared in 1984 (reprinted in 2001 and 2007, respectively. The article sets out to discover the main differences between the three editions and the possible reasons that may have triggered their publication in Estonia at those particular times. In order to approach the issues, a general framework derived from descriptive translation studies is employed with an emphasis on Gideon Toury’s chrestomatic treatment of translation norms. Thus an attempt is made to detect the preliminary translational norms regarding translation policy, particularly the choice of texts to be translated, as well as the matricial norms that concern the fullness of the translated text and are part of operational norms manifested in the translator’s decisions which, in two of the cases at hand, may also have been decisions made by the editor or the censor. Rudolf Sirge’s translation appeared at a time when Estonia had fairly recently been incorporated into the Soviet Union and there was a lack of children’s literature ideologically appreciated by the regime. This may account for the packaging of the book as a work with a strong didactic bent, while its primary audience was taken to be children and young adults for whom the protagonist served as an example of a hard-working and tenacious hero to be emulated by young Soviets. The target text has been considerably shortened as

Document available in extended abstract form only. Understanding the impact and fate of this gas phase is of significant importance within performance assessment and for the accurate long-term prediction of repository evolution. This paper describes the initial results from an ongoing experimental study to measure the two-phase flow behaviour of the Callovo-Oxfordian argillite from the Bure underground research laboratory (URL) in France, using the custom-designed BGS permeameter. The primary objectives of the study are to measure: (i) the hydraulic conductivity and intrinsic permeability; (ii) the capillary displacement pressure; (iii) the effective gas permeability and relative permeability to gas for a range of conditions; and (iv) the post-test gas saturation. During testing, the specimen, a cylinder of 54 mm thickness, cut perpendicular to bedding, is subject to an isotropic confining stress, with fluids injected through the base of the specimen. A novel feature of the apparatus is the use of porous annular guard-ring filters around the inflow and outflow filters. The pressures in these two 'guard-rings' can be independently monitored to provide data on the distribution of pressure and anisotropy of the sample. Initial measurements, performed on a specimen orientation perpendicular to the bedding plane, have been divided into three components: re-saturation and consolidation; hydraulic properties; gas behaviour. During the initial period of equilibration, re-saturation of the sample were noted. Net volume change due to re-saturation closely agreed with pre-test geotechnical measurements of water saturation, suggesting the bulk of the gas phase was resident in non-dilatant pores and that the specimen was fully saturated at the onset of testing. A two step consolidation test was then performed with confining pressure raised to 11 MPa for 5 days and then to 12.5 MPa for a further 8 days. Values for drained bulk modulus based on the total volume of fluid

Occupational use of computers has increased rapidly over recent decades, and has been linked with various musculoskeletal disorders, which are now the most commonly diagnosed occupational diseases in Estonia. The aim of this study was to assess the prevalence of musculoskeletal pain (MSP) by anatomical region during the past 12 months and to investigate its association with personal characteristics and work-related risk factors among Estonian office workers using computers. In a cross-sectional survey, the questionnaires were sent to the 415 computer users. Data were collected by self-administered questionnaire from 202 computer users at two universities in Estonia. The questionnaire asked about MSP at different anatomical sites, and potential individual and work related risk factors. Associations with risk factors were assessed by logistic regression. Most respondents (77%) reported MSP in at least one anatomical region during the past 12 months. Most prevalent was pain in the neck (51%), followed by low back pain (42%), wrist/hand pain (35%) and shoulder pain (30%). Older age, right-handedness, not currently smoking, emotional exhaustion, belief that musculoskeletal problems are commonly caused by work, and low job security were the statistically significant risk factors for MSP in different anatomical sites. A high prevalence of MSP in the neck, low back, wrist/arm and shoulder was observed among Estonian computer users. Psychosocial risk factors were broadly consistent with those reported from elsewhere. While computer users should be aware of ergonomic techniques that can make their work easier and more comfortable, presenting computer use as a serious health hazard may modify health beliefs in a way that is unhelpful.

Whole-word frequency and inflectional paradigm size facilitate Estonian case-inflected noun processing.

Estonian is a morphologically rich Finno-Ugric language with nominal paradigms that have at least 28 different inflected forms but sometimes more than 40. For languages with rich inflection, it has been argued that whole-word frequency, as a diagnostic of whole-word representations, should not be predictive for lexical processing. We report a lexical decision experiment, showing that response latencies decrease both with frequency of the inflected form and its inflectional paradigm size. Inflectional paradigm size was also predictive of semantic categorization, indicating it is a semantic effect, similar to the morphological family size effect. These findings fit well with the evidence for frequency effects of word n-grams in languages with little inflectional morphology, such as English. Apparently, the amount of information on word use in the mental lexicon is substantially larger than was previously thought. Copyright © 2018 Elsevier B.V. All rights reserved.

Full Text Available The purpose of the study was to find out whether the conceptual connection of emotion and motion is holding in the domain of personality traits. In a quantitative study 40 Estonian terms of personality traits were investigated and a conclusion was driven that, indeed, the qualities of emotionality and motion are perceived as co-present characteristics. In further data analysis some visualized measures were applied in order to get further insights into the hidden structure of the data. The self-organizing map (SOM analysis revealed an additional dimension of axiological evaluations present in the semantics and the SOM meta-analysis technique revealed groups of near synonymous words as well as gave overview of the more general structure common in the two data sets. The latter was tentatively explained by the person’s habitual level of activation.DOI: http://dx.doi.org/10.5128/ERYa6.21

History of experimental psychology from an Estonian perspective.

2007-11-01

A short review of the development of experimental psychology from an Estonian perspective is presented. The first rector after the reopening of the University of Dorpat (Tartu) in 1802, Georg Friedrich Parrot (1767-1852) was interested in optical phenomena which he attempted to explain by introducing the concept of unconscious inferences, anticipating a similar theory proposed by Herman von Helmholtz 20 years later. One of the next rectors, Alfred Wilhelm Volkmann (1800-1878) was regarded by Edwin Boring as one of the founding fathers of the experimental psychology. Georg Wilhelm Struve (1793-1864) played an essential part in solving the problem of personal equations. Arthur Joachim von Oettingen (1836-1920) developed a theory of music harmony, which stimulated his student Wilhelm Friedrich Ostwald (1853-1932) to study colour harmony. Emil Kraepelin (1856-1926), the founder of modern psychiatry, is by far the most important experimental psychologist who has worked in Estonia. His successor Wladimir von Tchisch (1855-1922), another student of Wilhelm Wundt, continued Kraepelin's work in experimental psychology. The lives of Wolfgang Köhler (1887-1967), who was born in Reval (Tallinn), and Oswald Külpe (1862-1915), who graduated from the University of Dorpat, extended the link between the history of experimental psychology and Estonia. Karl Gustav Girgensohn (1875-1925), the founder of the Dorpat School of the psychology of religion, stretched the use of experimental methods to the study of religious experience.

orthogonal to the plane strain direction, is in contact with a hard transparent window. The deformation of this surface is representative of the deformation in the whole specimen, up to and beyond strain localization. Therefore the evolution of the strain field in the sample can be measured by digital image correlation (DIC) of photographs taken of this surface. It is noted that the cell can sustain a confining pressure up to 100 MPa and so the regime of deformation in soft rocks from brittle through to ductile can be studied. Moreover, the stress path that is imposed to the specimen is not an axisymmetric state and is more realistic with respect to the paths followed in the field. In the selected results, we analysed the process of failure in the Callovo-Oxfordian argillite. First, strain localization under the form of shear bands propagate through the specimen, and then cracks born and propagate in the middle of the band. Complex patterns of cracks, with sets of conjugated cracks are observed in some case. The effect of the mean stress applied during tests on the failure is also observed. The kinetic of crack propagation is studied quantitatively, using the displacement field measured by DIC. The displacement gap on cracks is decomposed in a sliding component and a opening. The mechanical response of argillite specimens is also presented, with the link between post peak response (stress softening) and localization. (authors)

Iseseisvusdeklaratsioonid 1776–1918. The Estonian Declaration of Sovereignty: An Example of the Civilizing Force of Hypocrisy

Full Text Available Sovereignty has been characterised as a form of “organized hypocrisy”, a system governed by a set of rules that are generally recognised as binding and yet are continually infringed upon by the most powerful actors. This idea can be extended to analyse the role of sovereignty within the Soviet Union. The Soviet Union was nominally governed by a Constitution which endowed the Union Republics with the right of secession, but there was no realistic possibility of exercising this right. One should not rush to conclude, however, that the actual wording of the Soviet Constitution of 1977 was entirely without relevance. As Jon Elster has argued, hypocrisy can have a “civilizing force” when the need to appear impartial and to retain public credibility forces actors to choose a strategy they would not choose otherwise. A good example of this kind of argumentative constraint is offered by the dilemma faced by the Soviet leadership after the mid-1980s, as it became reluctant to use military force to suppress independence movements within the Baltic States while, at the same time, promising to give more weight to the Soviet Constitution and respect the “sovereignty” of the Union Republics. In this setting, the ambiguity of the word “sovereignty” could be played upon by a whole gamut of political movements in order to further their agenda, from local communists eager to expand their autonomy within the Soviet system to those making an explicit bid for the restoration of independence. Significant legal and political changes could be justified as mere conclusions from the constitutionally recognised status of the Union Republics – a strategy which was all the more effective as Moscow struggled to formulate an alternative line of constitutional interpretation that could be used to counter the Baltic claims. This exchange of opinions escalated into a constitutional conflict in November 1988, when the Estonian Supreme Soviet responded to

Comparative analysis of idiom selection and sequencing 5 in Estonian basic school EFL coursebooks

Full Text Available The article investigates the selection and sequencing of the idioms encountered in two locally-produced and international coursebook series currently employed in Estonian basic schools. It is hypothesized that there exists a positive correlation between idioms’ difficulty and coursebooks’ language proficiency level. The hypothesis is tested through a statistical analysis of the idioms found which are categorized in terms of their analysability into three categories where category 1 includes analysable semi-literal idioms, category 2 comprises analysable semi-transparent idioms, and category 3 encompasses non-analysable opaque idioms, and then analysed through an online language corpus (British National Corpus. The results of the study reveal that the coursebook authors under discussion have disregarded idioms’ frequency as a criterion for selection or sequencing, whereas the factor utilized to some extent is the degree of analysability.

Eesti patsient. Haiguse ja haige inimese kujutamise mudel 19. sajandi eesti kultuuris ja kirjasõnas. The Estonian Patient: A Model for the Representation of Illness and the Ill in 19th Century Estonian Culture and Letters

Directory of Open Access Journals (Sweden)

Janek Kraavi

2012-04-01

Full Text Available The portrait of the 18th and 19th century „Estonian patient” sketched in this article is a theoretical model of the ill person, based mainly on literary texts, but with reference to a variety of scientific and popular-scientific material. The point of departure is the classic postcolonial theorist, Frantz Fanon, in whose writings medicine, healing, and discourse on such topics are seen as the functioning of a specific colonial practice. The most notable characteristic of the figure of the Estonian patient is non-communicativeness. Communication is avoided and feared primarily because it has to be directed toward those in higher positions of power, or to institutions that embody power (the apothecary, the hospital. While these traits also characterize the separation between peasants and their rulers more generally, in a situation of illness the exclusion is felt with a double intensity. Sickness casts the peasant in a double bind: when in need of help or healing, contact across the divide between social rank, and – more broadly, between two cultures and ways of understanding the world, becomes unavoidable. In such situations, illness signifies an intensification of the gap in social standing. The ill person, who already stands on a lower rung of the social hierarchy, becomes all the more marginalized. In keeping with these observations, the real reason behind indecisiveness and refusal of medical treatment may well be an effort to avoid or postpone humiliation on the basis of lower social standing. Other contributing factors might include unconscious resistance – or even a conscious model of resistance – in the psyche, which manifests as an avoidance of communication. The content and motivating force for the model is not heroism, but rather a sense of shame. Indeed, behind the context of medical culture lurks ethnic and material isolation. The individual’s economic situation, living conditions, education and – most important – his

Full Text Available The aim of this article is to provide an overview of translations of English literature into Estonian between 1779 and 1917. There is an attempt to analyse the texts by describing them on the basis of, or in their departure from, a text or texts that chronologically and logically precede them. The discussion includes the nature of the transfer and the changes that have been made to the text, either because they existed in the source or mediating text or because of the expectations or requirements in the receptor, i.e. Estonian culture. The translated texts are seen in their historical-cultural context. For the analysis, a corpus of translated texts – religious, fiction, drama and non-fiction (published in a book form was compiled. The general orientation of Estonia until the 1880s was to the German cultural sphere. So the first translations of English literature were made via a mediating language, which was German. English Puritan writers were introduced by the Pietist missionaries with the aim of spreading their teachings in the second half of the 18th century. At about the same time the narrative element was introduced into stories with religious content.

. C) was conducted in order to identify the parameters controlling the overall reactivity of the system. This sensitivity analysis included kinetic parameters for selected minerals, diffusion coefficient, corrosion rate, and gas partial pressure. Another set of calculations was also performed in non-isothermal conditions using the variable temperature field resulting from the heat produced by the waste packages. Modeling results in the reference case show that the glass alteration products mainly consist of zeolites (gyrolite, natrolite) and pure silica minerals (chalcedony). Steel corrosion products are distributed as follows: iron oxides (magnetite or goethite) at the core of the canister; iron silicates (cronstedtite), aluminosilicates (chamosite, Fe-saponite), and sulphide (pyrrhotite) precipitate at the interface between glass and argillites. In the argillites, primary minerals such as dolomite, smectites and calcite are destabilized close to the canister surface. These minerals disappear in favour of gyrolite, natrolite, chalcedony and philippsite-K. The sensitivity analysis shows that the relative amount and evolution in space and time of these secondary minerals strongly depend on the corrosion rate and the release of gas (H 2 and possibly CH 4 ) in the system. The relative intensity of the transport process (diffusion coefficient) and mineral reaction rates (kinetic rate and reactive surface area) also strongly influence the evolution of the system (nature of secondary phases, porosity, gas pressure...). These reaction pathways and para-genesis predicted by the calculations are qualitatively supported by 'short-term' (∼1 year) experiments. A significant reduction of porosity is systematically predicted at the interface between the different materials and is also locally observed in the different materials depending on the simulation conditions, e.g. depending on the corrosion rate. An overall decrease of the reactivity of the system is also

In order to perform retrospective estimations of radiation doses seven years after the nuclear accident in Chernobyl, the frequencies of chromosomal aberrations in the peripheral blood lymphocytes of individuals living in contaminated areas around Chernobyl and the Estonian clean-up workers were determined. The first study group composed of 45 individuals living in four areas (i.e. Rechitsa, Komsomolski, Choiniki and Zaspa) in the vicinity (80-125 km) of Chernobyl and 20 individuals living in Minsk (control group - 340 km from Chernobyl). The second study group (Estonian clean-up workers) composed of 26 individuals involved in cleaning up the Chernobyl for a different period of time (up to 7 months) and a matched control group consisting of 9 probands. Unstable aberrations (dicentrics and rings) were scored in Giemsa stained preparations and stable aberrations (translocations) were analyzed using chromosome specific DNA libraries and fluorescence in situ hybridization (FISH) technique. For both study groups the estimated average dose is between 0,1-0,4 Gy. Among the people living in the contaminated areas in the vicinity of Chernobyl, a higher frequency of numerical aberrations (i.e. trisomy, hyper diploidy) was evident

The focus of research within the Spent Fuel and Waste Science and Technology (SFWST) (formerly called Used Fuel Disposal) Campaign is on repository-induced interactions that may affect the key safety characteristics of EBS bentonite and an argillaceous rock. These include thermal-hydrologicalmechanical- chemical (THMC) process interactions that occur as a result of repository construction and waste emplacement. Some of the key questions addressed in this report include the development of fracturing in the excavation damaged zone (EDZ) and THMC effects on the near-field argillaceous rock and buffer materials and petrophysical characteristics, particularly the impacts of temperature rise caused by waste heat. This report documents the following research activities. Section 2 presents THM model developments and validation, including modeling of underground heater experiments at Mont Terri and Bure underground research laboratories (URLs). The heater experiments modeled are the Mont Terri FE (Full-scale Emplacement) Experiment, conducted as part of the Mont Terri Project, and the TED in heater test conducted in Callovo-Oxfordian claystone (COx) at the Meuse/Haute-Marne (MHM) underground research laboratory in France. The modeling of the TED heater test is one of the Tasks of the DEvelopment of COupled Models and their VAlidation against EXperiments (DECOVALEX)-2019 project. Section 3 presents the development and application of thermal-hydrological-mechanical-chemical (THMC) modeling to evaluate EBS bentonite and argillite rock responses under different temperatures (100 °C and 200 °C). Model results are presented to help to understand the impact of high temperatures on the properties and behavior of bentonite and argillite rock. Eventually the process model will support a robust GDSA model for repository performance assessments.

Full Text Available Until recently, the treatment of Estonian literature from the beginning of the 20th century has been influenced by the literary and cultural activities and programmatic articles of the Young Estonia movement. Current research on Young Estonia has addressed their more everyday realm of activity, which has heretofore received less attention: the Young Estonians as readers of the new works of their literary contemporaries and their practical criticism in reviews, particularly in daily newspapers. This article uses a receptionhistorical approach to analyze a large body of source material: the Young Estonians voluminous critical oeuvre in the period 1905–1915. The Young Estonians to be examined are all members of the core group of the movement: Gustav Suits, Bernhard Linde, Aino Kallas, Johannes Aavik, Villem Grünthal-Ridala, Jaan Oks, August Alle, and Johannes Semper. Within the larger framework of collective horizons of expectation, the focus of the study is the critics` concept of the reader. In addition, I will briefly discuss the dynamics of how such conceptions change. Research results indicate that in critical reviews from the time of Young Estonia, the topic of the reader was addressed from different standpoints depending on the addressee. Texts directed rhetorically toward a broad readership are characterized by the pursuit of objectivity and generalizations. When the concept of the reader is critic-centered, the text emphasizes subjective judgments, experience, and emotion. When focusing on the author and the text, the reviewer describes the influence on the reader, the cause of which is either the literary work directly or the author’s genius. In the case of polemic on the subject of reading, found mainly in responses written to reviews, the writer interprets another reader (or other readers` reading, opposing it to his or her own. When we follow the way the readers of Young Estonia and the Young Estonians themselves handle the

Chemical composition of anthropogenic particles on needles collected close to the Estonian oil-shale power plants

1995-01-01

Within the countries surrounding the Baltic Sea, north-eastern Estonia is among the most polluted areas. Emissions from the oil-shale power plants produce air pollution problems both locally and on a larger scale. In the atmosphere, pollutants mix and convert. Consequently, the particles deposited due to the use of oil-shale can have various chemical compositions. From the point of view of air chemistry, ecological effects and air pollution modelling, knowledge of the chemical composition of the deposited particles can be of great value. The aim of this work was to study the chemical composition of single anthropogenic particles occurring on needle surfaces in north-eastern Estonia and Southern Finland close to the Estonian oil-shale power plants. For the purpose, scanning electron microscopical microanalysis was used

Full Text Available Bernhard Linde (1886–1954 was a recognized and prolific Estonian theatre critic of the first quarter of the 20th century, who mediated and propagated western as well as eastern European theatrical innovations. In addition, he was active as a literary and art critic, publisher, and proponent of libraries, to a modest extent he was a prose writer and poet. Unquestionably, however, Bernhard Linde’s most prominent role was as one of the founding members of the literary movement Young Estonia. He was the group’s first general manager; later on, he was the secretary of the Estonian Writers’ Association Young Estonia, and the chairman of the board of the Young Estonia Publishing House. Linde’s formal education culminated in graduation from Tartu University as a Slavic philologist; he was the only member of the Young Estonia group to demonstrate serious and sustained interest toward Slavic cultures and peoples. Linde was a contradictory figure, evoking a range of responses from his contemporaries: on the one hand, there was the unbelievably broad range of his participation in cultural life, his organizing skills and business instincts in directing publishing houses; on the other hand, a superficiality in his writings, his often rash and subjective style as a critic, and his financial intrigues. If one adds in Linde’s stubbornness, egocentrism, and intense spirit of protest, which often led to lawsuits, the outcome is the portrait of an extremely complicated, fascinating, and passionate man—both in his creative work and his personal life Linde guaranteed a place for himself in literary history through a small catch of texts: a few foundational essays (for example, on August Kitzberg, a translation of Balzac’s Le père Goriot, the essay collection Omad ja võõrad (Own and Foreign and a travel book focusing on the literature and theatre of eastern Europe (Loova Kesk-Euroopa Poole (Toward A Creative Central Europe.

Full Text Available The second larger Estonian R&D and Innovation Strategy ‘Knowledge-based Estonia 2007-2013’ is aimed at continuing the advancement of research and development efforts towards an innovative knowledge-based society and economic system in Estonia. Fostering of knowledge-based high-tech industries is seen as paramount for retaining country’s competitive advantage. However, the mid-term evaluations indicate that several goals of the strategy might not be achievable by 2013. In fact, the policy measures have been much more successful in developing scientific research, as indicated by increased international publication, number of patents, and number of researchers and engineers. The advances in development of high-tech products and services through innovations are noticeable but less prominent. The purpose of this study is to suggest the role for demand-side innovation policies in helping to advance commercial development and innovation

Geology of the Syncline Ridge area related to nuclear waste disposal, Nevada Test Site, Nye County, Nevada

1980-01-01

The Syncline Ridge area is in the western part of Yucca Flat, Nye Co., Nev. Drill holes, geophysical surveys, mapping, and laboratory studies during 1976 through 1978 were used to investigate argillite in unit J (Mississippian) of the Eleana Formation (Devonian and Mississippian) as a possible nuclear waste repository site. Argillite in unit J has a minimum stratigraphic thickness of at least 700 m. The argillite underlies most of the Syncline Ridge area east of the Eleana Range, and is overlain by Quaternary alluvium and the Tippipah Limestone of Syncline Ridge. At the edges of the Syncline Ridge area, alluvium and volcanic rocks overlie the argillite. The argillite is underlain by more than 1000 m of quartzite, siliceous argillite, and minor limestone in older units of the Eleana Formation. These older units crop out in the Eleana Range. The area is divided into southern, central, and northern structural blocks by two lateral faults. The southern and central blocks either have volumes of argillite too small for a repository site, or have irregular-shaped volumes caused by Mesozoic high-angle faults that make the structure too complex for a repository site. The northern block appears to contain thick argillite within an area of 6 to 8 km 2 . The postvolcanic history of the Syncline Ridge area indicates that the area has undergone less deformation than other areas in Yucca Flat. Most of the late Tertiary and Quaternary deformation consisted of uplift and eastward tilting in the Syncline Ridge area. Preliminary engineering geology investigations indicate that although the competency of the argillite is low, the argillite may be feasible for construction of a nuclear waste disposal facility. Physical, thermal, chemical, and mineralogical properties of the argillite appear to be within acceptable limits for a nuclear waste repository

Chemistry of the Estonian oil-shale kukersite

Kogerman, P N

1931-01-01

Estonian oil shale is one of the oldest and richest oil shales in the world. The deposits occur in the Middle-Ordovician strata having a total thickness of 2.2 meters. The ultimate composition of the kerogen varied within the following limits: carbon 76.5 to 76.7 percent, hydrogen 9.1 to 9.2 percent, nitrogen 0.2 to 0.4 percent, sulfur 1.6 to 2.2 percent, chlorine 0.5 to 0.7 percent, and oxygen (by difference) 11.2 to 12.2 percent. The composition of kukersite kerogen corresponds nearly to the empirical formula (C/sub 8/H/sub 11/O)n. One of the most significant differences between kukersite, coal, and lignite is the amount of alkali-soluble substances present. Kukersite has almost no humic acids. Samples of kukersite were brominated and chlorinated. The halogenated shales showed a solubility in absolute alcohol of 26 percent compared to only 0.31 percent for untreated shale. Enriched shale (4.5 percent ash) did not react with chlorine as much as did raw shale. Apparently the mineral matter acted catalytically during chlorination. The amount of soluble extract obtained by solvent treatment of kukersite ranged from 0.22 percent with chloroform to 2.20 percent with tetrachloroethane. Heat was the most effective agent for the depolymerization of kukersite kerogen. The percentage loss of weight due to drying in air was much less than in the presence of carbon dioxide. The results indicated that on drying in air, the powdered shale loses water and a volatile substance, probably the oxides of carbon, up to 80/sup 0/C. Carbon dioxide was also found to be present in the gases eliminated at the temperature of initial decomposition. Pulverized shale, heated for 6 hours at 220/sup 0/C, lost 2.6 percent of its weight; its solubility in carbon disulfide was 2.11 percent. Kukersite kerogen was formed from compounds that were resistent to bacteriological decomposition, such as waxes and resins, plus decomposition products of proteins, cellulose, and putrefaction products of

Eesti Rahva Muuseumi strateegiad ja praktikad rahvaga suhtlemisel muuseumi algusaastatel / Estonian National Museum: Public communication strategies and practices in the initial years

Full Text Available Until recently the museum phenomenon as the valuator of the indigenous culture in the context of the awakening national consciousness has received little attention. The evolution of the idea of the Estonian National Museum (ENM and its realization reflects the story of the Estonian people maturing into a nation. The museum was founded by a few dedicated persons and it took a long time before the general public recognised it as the museum for the Estonian people. The main purpose of this research is to ascertain how relations developed between the public and the museum in its initial years and what were the museum strategies in declaring its objectives. After the official foundation of the ENM in 1909 the museum narrative can be divided into two main parts. First, work inside the museum, the compilation and arrangement of collections. This was, above all, the work of the collection committee and organizing heritage collection trips. Collections constitute the basis of a museum – therefore the primary and most important task of the established museum was the collection of heritage items. The collections were started immediately after the foundation of the museum; within the first ten years approximately 20,000 items were collected, approximately two thirds of the items in the years 1911–1913. The phenomenon that a museum where people worked mainly without a salary for the benefit of their homeland, with the set aim to empty the whole of Estonia of heritage items parish by parish and succeeded in engaging dozens and dozens of people for this work, is probably exceptional in world history. As a result, the museum acquired not only voluminous but also valuable item collections, which reached the museum before the devastating First World War. The timing was favourable. There were enough old artefacts left, although most collectors complained in their diaries that there was nothing interesting to be found any more. However, the majority of the

The purpose of this comparative study is to describe the differences between Finnish and Estonian students evaluations about their client-centeredness and educational support they received to develop it. Client-centeredness has many positive effects on the quality and effectiveness of care. However, some deficiencies have been identified in the client-centeredness of nursing staff. Research on the subject has been limited, and we lack knowledge of graduating students' competence in client-centeredness and the support of their education to develop it. The sample consisted of 390 undergraduate nursing students, 195 from Finland and 195 from Estonia. The data were collected in 2009 using the structured five-point scale questionnaire. The questionnaire was designed to measure students' client-centeredness and the educational support they received from nursing education. The data were analyzed by the PASW Statistics 18-programme using descriptive statistics, Kolmogorov-Smirnov test and Mann-Whitney U-test. Predominantly, students in both countries evaluated their level of client-centeredness high. The Estonian students generally evaluated their client-centeredness higher compared to the Finnish students. The same applied to support provided by nursing education. The greatest differences were related to education and particularly theoretical teaching. In Estonia, students' client-centeredness manifested itself more in politeness and willingness to serve clients, whereas respecting the clients' values was emphasized in Finland. Students' requisites, referred here as knowledge, skills and abilities to implement client-centered nursing, for client-centeredness had deficiencies, and the support from education was also the weakest regarding these aspects. In future, education on development of nursing activities, acquisition of knowledge and services provided by health care as well as legislation should be enhanced, since these areas proved the most difficult for the students

Estonian energy system: Proposals for the implementation of a cogeneration strategy

Since the Soviet era Estonia inherited oil-shale-based electricity plants, with a capacity of 3000 MW. Oil shale now provides Estonia with very low electricity prices. However, most of the stations are very old. Half of them were built before 1965, and sooner or later the old oil shale production units will have to be replaced. Estonia will then have to face serious increases in electricity production prices. At the same time Estonia has problems in restoring its district heating systems. The prices are rising and may consumers have converted to other heating sources such as electric heating. The major long-term strategic policy choices to make in Estonia are to decide (1) whether the oil shale power stations should be replaced by new centralized production units such as new oil shale stations or nuclear power, or (2) whether the electricity production should be decentralized. In the centralized solution (oil shale or nuclear power), the domestic heating will be left to boilers or electric heating leading to a very high primary energy supply. In the decentralized solution, Estonia could benefit from the advantage of cogeneration leading to very low fuel consumption. But this latter strategy depends on the restoration of the district heating systems. This article seeks to form a strategy to improve the efficiency of the Estonian energy system by increasing the use of cogeneration. (author)

A study of 739 conscripts aged 17 years from the town of Tartu and from the Tartu county was performed. Height, weight, 33 anthropometric measurements and 12 skinfolds were measured. The data were classified into five height-weight mean and SD-classes applying the Estonian reference values for this age and sex (Grünberg et al. 1998). There were 3 classes with conformity between height and weight class: 1--small (small height and small weight), 2--medium (medium height and medium weight), 3--large (large height and large weight), 4--weight class dominating (pyknomorphic) and 5--height class dominating (leptomorphic). It was found, that in classes 1, 2 and 3 the height and weight increase was in accordance with the increase in all heights, breadths and depths, circumferences, skinfolds, body fat, muscle and bone mass. In class 4 circumferences, skinfolds, body fat and muscle mass were bigger. In class 5 all heights and the relative bone mass were bigger. The present investigation confirms the assumption that the five height-weight mean and SD five-class system applying the Estonian reference values for classifying the anthropometric variables is suitable for seventeen-year-old conscripts. As well the border values of 5%, 50% and 95% for every anthropometrical variable in the five-classes were calculated, which may be helpful for practical classifying.

Argillite is a carbonaceous industrial by-product that is a potential source in environmentally friendly and source-saving construction industry. In this research, chemical and mineral composition as well as particle size distribution of argillite were studied and used to develop autoclave aerated concrete as partial substitute of quartz sand. Effect of the argillite as a mineral admixture in autoclave aerated concrete was investigated in terms of compressive and tensile strength, density, heat conductivity etc. The obtained results demonstrated an efficiency of argillite as an energy-saving material in autoclave construction composites.

1988. aasta suveräänsusdeklaratsioon: silmakirjalikkuse tsiviliseeriv mõju / The Estonian Declaration of Sovereignty: An example of the civilising force of hypocrisy

Full Text Available Sovereignty has been characterised as a form of “organised hypocrisy”, a system governed by a set of rules that are generally recognised as binding and yet continually infringed by the most powerful actors. This idea can be extended to analyse the role of sovereignty within the Soviet Union. The latter was also nominally governed by a constitution which endowed the Union Republics with the right of secession, but there was no realistic possibility of exercising this right. One should not rush to conclude, however, that the letter of the Soviet Constitution of 1977 was entirely without relevance. As Jon Elster has argued, hypocrisy can be a “civilising force” when the need to appear impartial and retain public credibility forces actors to choose a strategy they would not have chosen otherwise. A good example of this kind of argumentative constraint is offered by the dilemma faced by the Soviet leadership after the mid-1980s, as it became reluctant to use military force to suppress independence movements within the Baltic States while, at the same time, promising to give more weight to the Soviet Constitution and respect the “sovereignty” of the Union Republics. In this setting, the ambiguity of the word “sovereignty” could be used by a whole gamut of political movements in order to further their agenda, from local communists eager to expand their autonomy within the Soviet system to those making an explicit bid for the restoration of independence. Significant legal and political changes could be justified as mere conclusions from the constitutionally recognised status of the Union Republics — a strategy which was all the more effective as Moscow struggled to formulate an alternative line of constitutional interpretation that could be used to counter the Baltic claims. This exchange of opinions escalated into a constitutional conflict in November 1988 when the Estonian Supreme Soviet responded to proposed amendments to the Soviet

Full Text Available This paper aims to describe the writing process of native Russian‑speaking students in Estonian as a second language. 34 participants were given the assignment of writing a text in the L2. The written texts were then rated as being at levels from A2 to C1 according to the Common European Framework of Reference for Languages (CEFR. The data were collected by computer keystroke logging and analysed based on the concept of a ‘micro-context’. Micro-contexts were analysed according to their frequency and duration and were compared across proficiency levels. The results show that writing in the L2 is not a smooth process. The longest transitions in micro-contexts reveal that the most cognitive effort is made between paragraphs and sentences and when deletions are involved. The growing number of consecutive deletions demonstrates that even with developing proficiency, the linear production text is subject to constant revision, correction and modification.

Experiences of a long-term randomized controlled prevention trial in a maiden environment: Estonian Postmenopausal Hormone Therapy trial

Full Text Available Abstract Background Preventive drugs require long-term trials to show their effectiveness or harms and often a lot of changes occur during post-marketing studies. The purpose of this article is to describe the research process in a long-term randomized controlled trial and discuss the impact and consequences of changes in the research environment. Methods The Estonian Postmenopausal Hormone Therapy trial (EPHT, originally planned to continue for five years, was planned in co-operation with the Women's International Study of Long-Duration Oestrogen after Menopause (WISDOM in the UK. In addition to health outcomes, EPHT was specifically designed to study the impact of postmenopausal hormone therapy (HT on health services utilization. Results After EPHT recruited in 1999–2001 the Women's Health Initiative (WHI in the USA decided to stop the estrogen-progestin trial after a mean of 5.2 years in July 2002 because of increased risk of breast cancer and later in 2004 the estrogen-only trial because HT increased the risk of stroke, decreased the risk of hip fracture, and did not affect coronary heart disease incidence. WISDOM was halted in autumn 2002. These decisions had a major influence on EPHT. Conclusion Changes in Estonian society challenged EPHT to find a balance between the needs of achieving responses to the trial aims with a limited budget and simultaneously maintaining the safety of trial participants. Flexibility was the main key for success. Rapid changes are not limited only to transiting societies but are true also in developed countries and the risk must be included in planning all long-term trials. The role of ethical and data monitoring committees in situations with emerging new data from other studies needs specification. Longer funding for preventive trials and more flexibility in budgeting are mandatory. Who should prove the effectiveness of an (old drug for a new preventive indication? In preventive drug trials companies may

Document available in extended abstract form only. Cronstedtite crystals experimentally formed during a cooling experiment (90 deg.C-40 deg. C) simulating the time-temperature evolution of the iron-clay system around the steel overpacks in nuclear waste disposal, were characterized by XRD, SEM and TEM study. Cronstedtite is a T-O phyllosilicate with general formula (Fe 2+ 3-x Fe 3+ x )(Si 2-x Fe 3+ x )O 5 (OH) 4 , with 0 2 ), Callovo-Oxfordian argillite (COx) of the Paris Basin (with a solution/COx mass ratio of 10) and metal iron (powder and plates, with an iron powder/COx mass ratio of 0.5). This system was put in Teflon-line autoclaves heated at (90±2) deg. C for 6 months; then the temperature was decreased every month by step of 10 deg. C until 40 deg. C. The XRD results on run products clearly show that the T-O phyllosilicates crystallize and replace the predominant clay in the starting argillite, e.g. illite-smectite mixed-layer clays when the experimental temperature decreases. The reflections at 7.1 Angstrom, 4.76 Angstrom, 3.55 Angstrom and 2.73 Angstrom indicate that the T-O phyllosilicate formed is cronstedtite, but this technique is not efficient to determine its polytype. The SEM analyses confirm the presence of cronstedtite and show the morphological evolution of crystals with the temperature. At 90 deg. C three morphologies are recognized: trigonal pyramids and cones with hexagonal or rounded cross-section (Fig. 1), these crystals coexist with hairy berthierine-like minerals, as described by [10] and [12] The three cronstedtite shapes are observed until 70 deg. C and at lower temperatures the pyramidal morphology is dominant. From the energy dispersive X-ray analyses, structural formula of cronstedtite were calculated. The Fe II / Fe III ratio was adjusted to fix the octahedron to 3 in the calculation of the structural formula. Slight differences in the chemical compositions of cronstedtites are noticed: the pyramidal crystals have more Fe 2+ in the

Supervision, mentorship and peer networks: how Estonian early career researchers get (or fail to get support

Jaana Eigi

2018-03-01

Full Text Available The paper analyses issues related to supervision and support of early career researchers in Estonian academia. We use nine focus groups interviews conducted in 2015 with representatives of social sciences in order to identify early career researchers’ needs with respect to support, frustrations they may experience, and resources they may have for addressing them. Our crucial contribution is the identification of wider support networks of peers and colleagues that may compensate, partially or even fully, for failures of official supervision. On the basis of our analysis we argue that support for early career researchers should take into account the resources they already possess but also recognise the importance of wider academic culture, including funding and employment patterns, and the roles of supervisors and senior researchers in ensuring successful functioning of support networks. Through analysing the conditions for the development of early career researchers – producers of knowledge – our paper contributes to social epistemology understood as analysis of specific forms of social organisation of knowledge production.

Diet has health consequences, which makes knowing the psychological correlates of dietary habits important. Associations between dietary habits and personality traits were examined in a large sample of Estonians (N = 1,691) aged between 18 and 89 years. Dietary habits were measured using 11 items, which grouped into two factors reflecting (a) health aware and (b) traditional dietary patterns. The health aware diet factor was defined by eating more cereal and dairy products, fish, vegetables and fruits. The traditional diet factor was defined by eating more potatoes, meat and meat products, and bread. Personality was assessed by participants themselves and by people who knew them well. The questionnaire used was the NEO Personality Inventory-3, which measures the Five-Factor Model personality broad traits of Neuroticism, Extraversion, Openness, Agreeableness, and Conscientiousness, along with six facets for each trait. Gender, age and educational level were controlled for. Higher scores on the health aware diet factor were associated with lower Neuroticism, and higher Extraversion, Openness and Conscientiousness (effect sizes were modest: r = .11 to 0.17 in self-ratings, and r = .08 to 0.11 in informant-ratings, ps < 0.01 or lower). Higher scores on the traditional diet factor were related to lower levels of Openness (r = -0.14 and -0.13, p < .001, self- and informant-ratings, respectively). Endorsement of healthy and avoidance of traditional dietary items are associated with people's personality trait levels, especially higher Openness. The results may inform dietary interventions with respect to possible barriers to diet change.

Organizational culture based on the example of an Estonian hospital.

The concept of organisational culture (also referred to later as OC) is one of the approaches in modern organisational analysis exploring the values, attitudes and beliefs behind human behaviour in the workplace. OC as a social phenomenon is considered to be important for the sustainability of every organisation. In the service sector, OC may affect the nature and quality of the services provided. The aim of this paper is twofold: on the one hand, to highlight the patterns of OC in a hospital; and, on the other hand, to outline relationships between OC and patient satisfaction. The study was conducted in Tartu University Hospital, one of the most influential health care organisations in Estonia. This paper has original value by presenting an insight into organisational culture in the Estonian health care sector, and the findings of the study will expand knowledge of OC in the health care sector in general. The OC instrument applied in a quantitative cross-sectional study was earlier developed according to the Competing Values Framework (CVF). Data from 456 medical and non-medical professionals were analysed using non-parametric tests of descriptive statistics. A factor analysis was performed to assess the instrument's compatibility for analysing the OC pattern in the health care sector. The dominant culture type in all the groups investigated was the Internal Processes type, mainly followed by the Rational Goal type, while different cultural patterns were observed in professional groups. The factor analysis yielded a three-subscale solution. Clinics with high patient satisfaction did not score more than clinics with low patient satisfaction in terms of the Human Relations type. In future studies a random sample design and a multidisciplinary approach to OC research should be followed in order to further explore OC patterns in hospitals and their consequences for different aspects of hospital performance.

As energy demand and prices continue to grow, oil shale might help mitigate the energy crisis—it can widely be found all over the world but so far has not been widely used. Estonia is unique in the world for producing a large majority of energy out of oil shale and has been set as an example in numerous papers covering oil shale deposits, technology etc. This paper is the first to analyse oil shale energy related workforce and provides scenario forecasts of the labour demand for the Estonian energy sector in 2010–2020. The contribution of the paper is twofold. First, the paper provides a valuable insight into oil shale energy related workforce, enabling to take into consideration the educational needs in countries where oil shale industry might be set up. Second, methodology-wise, the paper relates labour demand and supply to different scenarios of energy production capacities. The results illustrate problems related to aging of the workforce in energy production. If the existing trends continue in educational attainment in Estonia, there will be a serious shortage of high-skilled engineering and manufacturing specialists. Our method provides a simple yet reliable enough way to check for such problems early enough. - Highlights: ► This paper analyses oil shale energy related workforce and provides scenario forecasts. ► This is the first study to investigate the workforce related to oil shale energy production. ► The main workforce-related problem in the sector is ageing of the workforce. ► Workers immigrating to the sector during the Soviet times are at the retirement age. ► There will be a serious shortage of engineers for energy sector in the near future.

Full Text Available Any consideration of Estonian theatre from the point of view of biographical theatre needs to include the work of playwright and director Merle Karusoo. Productions based on various life narratives (diaries, letters, biographical interviews form the core of her work that can be defined as biographical or memory theatre. Her work has also been viewed within the context of community theatre or political theatre; Karusoo has herself referred to her work as sociological theatre. Life narratives have functioned in Karusoo’s productions as the basis for restoring oppressed or denied collective discourses of memory. Her productions emerged within the framework of the more general process of restoration of historical heritage and the rehabilitation of collective memory at the end of the 1980s and the beginning of the 1990s. Life story can be viewed as the essence of Merle Karusoo’s theatre. The personal in the life story in the production activates the emotional memory of the audience; for older generations such theatre facilitates a legitimisation of remembering one’s life story in entirety, and for younger generations it functions as a vehicle of collective, historical and national memory. The current article outlines the main stages of Karusoo’s biographical theatre, highlights major productions of each stage and provides an overview of their reception. Karusoo’s theatre dates back to 1980s. Productions based on life stories of the generations born in 1950s and 1960s, Meie elulood (Our Biographies and Kui ruumid on täis ...

The Baltic Klint beneath the central Baltic Sea and its comparison with the North Estonian Klint

Along its contact with the Baltic Shield, the margin of the East European Platform reveals a well-developed, flooded terraced relief. The most striking and consistent set of escarpments at the contact of the Lower Palaeozoic calcareous and terrigenous rocks, known as the Baltic Klint (BK), extends from northwest of Russia to the Swedish island of Öland. Marine seismic reflection profiling in 1990-2004 revealed the central Baltic Sea Klint (BSK) section in detail and enabled comparison of its geology/geomorphology with a classical klint-section onshore, namely the North Estonian Klint (NEK). The conception of the BK onshore, which is based on the land-sea separating terraced relief in northern Estonia, is not fully applicable beneath the sea. Therefore, we consider that the BSK includes the entire terraced Cambrian outcrop. We suggest the term "Baltic Klint Complex" to include the well-terraced margin of the Ordovician limestone outcrop, which is weakly developed in Estonia. Because of a steady lithological framework of the bedrock layers across the southern slope of the Fennoscandian Shield, the central BSK in the western and the NEK in the eastern part of the Baltic Homocline have largely identical morphologies. The North Estonian Ordovician limestone plateau with the calcareous crest of the BK extends across the central Baltic Sea, whereas morphological changes/variations along the Klint base occur due to the east-westerly lithostratigraphic/thickness changes in the siliciclastic Cambrian sequence. The verge of the NEK, located some 30-50 m above sea level, starts to drop in altitude as its east-westerly course turns to northeast-southwest in western Estonia. Further westwards, the BK shifts gradually into southerly deepening (0.1-0.2°) layers as its crest drops to c. 150 m below sea level (b.s.l.) near Gotska Sandön. This course change is accompanied by a considerable decrease in thickness of the platform sedimentary cover, as below the central Baltic Sea the

Document available in extended abstract form only. Petro-fabric and physico-chemical properties of Meuse/Haute-Marne Callovo-Oxfordian argillite have been extensively studied (e.g. Trouiller, 2006). This research project is aiming at establishing micro-macro models to link microstructural patterns and macroscopic measurements. In this context, data are acquired on the same samples at different scales: (a) microscopic scale (identification of mineralogical phases, mineral mapping, surface area, pore size distribution) and (b) macroscopic scale (hydraulic conductivity, elastic wave velocities, resistivity, thermal conductivity). Ultimately the resulting micro-macro models would be used by Andra to construct 3D representation of the petrophysical properties within the Callovo-Oxfordian formation by the mean of logging data. This project is part of the research programme TAPSS2000 (Present and past transfers in a sedimentary aquifer - aquitard system: a 2000 meter deep drill-hole in the Mesozoic of the Paris Basin). Data acquisition is performed on 9 cores (taken from 558.5 m to 619.5 m deep) of the deep borehole ANDRA EST433 located at Moultiers-sur-Saulx (Meuse, France). These data on the microstructure and the macroscopic physical behaviour of Callovo-Oxfordian show the following features: - The higher the P-and S- wave velocities, the higher the radiologic density measured by X-Ray tomography. These high values of velocities and density are associated with carbonates, the most rigid phase among the rock-bearing minerals. P-wave velocity measurements do not exhibit significant scale effect (i.e., logging vs laboratory). - The most heterogeneous samples (with regard to their values of elastic wave velocities and radiologic density) are located in the upper part of the Callovo-Oxfordian formation, where argillite is more carbonated. On the contrary, the most homogeneous cores that exhibit lower values of elastic wave velocities are located at deeper depths: they are

This paper presents the results of the distribution of trace elements in Estonian mires. Sixty four mires, representative of the different landscape units, were analyzed for the content of 16 trace elements (Cr, Mn, Ni, Cu, Zn, and Pb using AAS; Cd by GF-AAS; Hg by the cold vapour method; and V, Co, As, Sr, Mo, Th, and U by XRF) as well as other peat characteristics (peat type, degree of humification, pH and ash content). The results of the research show that concentrations of trace elements in peat are generally low: V 3.8 ± 0.6, Cr 3.1 ± 0.2, Mn 35.1 ± 2.7, Co 0.50 ± 0.05, Ni 3.7 ± 0.2, Cu 4.4 ± 0.3, Zn 10.0 ± 0.7, As 2.4 ± 0.3, Sr 21.9 ± 0.9, Mo 1.2 ± 0.2, Cd 0.12 ± 0.01, Hg 0.05 ± 0.01, Pb 3.3 ± 0.2, Th 0.47 ± 0.05, U 1.3 ± 0.2 μg g - 1 and S 0.25 ± 0.02%. Statistical analyses on these large database showed that Co has the highest positive correlations with many elements and ash content. As, Ni, Mo, ash content and pH are also significantly correlated. The lowest abundance of most trace elements was recorded in mires fed only by precipitation (ombrotrophic), and the highest in mires fed by groundwater and springs (minerotrophic), which are situated in the flood plains of river valleys. Concentrations usually differ between the superficial, middle and bottom peat layers, but the significance decreases depending on the type of mire in the following order: transitional mires - raised bogs - fens. Differences among mire types are highest for the superficial but not significant for the basal peat layers. The use of peat with high concentrations of trace elements in agriculture, horticulture, as fuel, for water purification etc., may pose a risk for humans: via the food chain, through inhalation, drinking water etc.

Full Text Available The article examines the prototypicality phenomena in the Estonian language’s lexical-semantic domain of “musical instruments”. There are two groups of people under examination: (i those who consider themselves actively involved in music (practitioners, and (iithose who don’t (listeners. To elicit basic terms, a cognitive salience index is used. The results show that the main common feature between the groups is that the basic level consists of the same members: klaver ‘piano’, kitarr ‘guitar’ and viiul ‘violin’. While klaver and viiul are stable in their nature, the salience of kitarr varies greatly, as listeners put it in the leading position and practitioners nearly leave it out of the basic level. Generally, the two groups share the same category structure,as based on cognitive salience index values both have: (i three basic terms, (ii a connecting group, and (iii the rest of the category members with their index values decreasing toward zero.

Resumption of luteal activity postpartum and fertility were investigated in an Estonian Holstein high milk production and good fertility dairy herd. Body condition was scored after every 10 days in 54 multiparous dairy cows (71 lactations) calving inside from December to March during 4-year period. Blood samples were taken 1-14 days before calving and 1-14, 28-42 and 63-77 days after calving: analytes estimated were serum aspartate aminotransferase (AST), glucose, ketone bodies, total cholesterol, non-esterified fatty acids and triglycerides. The general linear mixed model was used to compare the data for cows with different characteristics in luteal activity postpartum based on their milk progesterone profiles. Forty-five per cent of cases had abnormal profiles; delayed resumption of ovarian cyclicity postpartum (DC) was the most prevalent abnormality. There was no difference in body condition scores between the groups. The DC and prolonged luteal phase groups had higher serum AST activity (p fertility.

The present paper is based on a WHO Collaborative Cross-National Study "Health Behavior in School-Aged Children (HBSC)." It aimed at describing and analyzing how the sexual behaviors of 13- to 15-year-old Estonian school children were associated with self-reported depressive feelings and suicidality. Distinctive behavioral traits in relation to age of first sexual intercourse were also investigated. Self-reported questionnaires from school children (n = 3,055) were analyzed. In total, 15.2% of school children reported being nonvirgin. Among 13-year-olds, 2.9% of girls and 6.8% of boys were nonvirgins. Approximately 25% of the 15-year-old girls and boys were nonvirgins. The likelihood of depressive feelings and suicidal ideation increased significantly in both genders with loss of virginity. Boys who had lost their virginity at 13 years or younger were 4.2 times more likely to have suicidal thoughts; comparable girls were 7.8 times more likely to have suicidal thoughts. Compared to virgins, youths who had lost their virginity reported poor self-assessed health and more risk behaviors in themselves and their peers. Experiences of sexual intercourse increased the odds ratios for depressive feelings and suicidality. The earlier sexual intercourse was initiated, the greater were the odds of lower mental well-being. Risk behaviors emerged as a complex phenomenon requiring complex prevention.

To examine non-cancer morbidity in the Estonian Chernobyl cleanup workers cohort compared with the population sample with special attention to radiation-related diseases and mental health disorders. Register-based cohort study. Estonia. An exposed cohort of 3680 men (cleanup workers) and an unexposed cohort of 7631 men (population sample) were followed from 2004 to 2012 through the Population Registry and Health Insurance Fund database. Morbidity in the exposed cohort compared with the unexposed controls was estimated in terms of rate ratio (RR) with 95% CIs using Poisson regression models. Elevated morbidity in the exposed cohort was found for diseases of the nervous system, digestive system, musculoskeletal system, ischaemic heart disease and for external causes. The most salient excess risk was observed for thyroid diseases (RR=1.69; 95% CI 1.38 to 2.07), intentional self-harm (RR=1.47; 95% CI 1.04 to 2.09) and selected alcohol-related diagnoses (RR=1.25; 95% CI 1.12 to 1.39). No increase in morbidity for stress reactions, depression, headaches or sleep disorders was detected. No obvious excess morbidity consistent with biological effects of radiation was seen in the exposed cohort, with the possible exception of benign thyroid diseases. Increased alcohol-induced morbidity may reflect alcohol abuse, and could underlie some of the higher morbidity rates. Mental disorders in the exposed cohort were probably under-reported. The future challenge will be to study mental and physical comorbidities in the Chernobyl cleanup workers cohort. Published by the BMJ Publishing Group Limited.

cancellation of volumetric strains rate, in particular of dilation for high shear strains, - An ultimate friction angle related to the critical state angle, - Volumetric strains contractant or dilatant, depending on the state of stress. The delayed behaviour is implemented by the definition of a long term strength threshold, and allows taking into account: - The effect of the excavation average rate, - The effect of a stopping in excavation works, - The long-term behavior of an unsupported face heading. This advanced constitutive model is described in the paper from a conceptual point of view. The aim is not to define theoretical equations but only to expose the main physical concepts implemented. To illustrate the relevance of the model, an application to the Meuse/Haute-Marne Argillite is given from a simple example. (authors)

Full Text Available Abstract Background Objectives of the study were to document the impact of some management factors on the occurrence of clinical mastitis in primiparous dairy cows and to identify common udder pathogens of clinical mastitis in freshly calved heifers and multiparous cows on the day of calving. Methods A one-year study was conducted during 2004 and 2005 in 11 selected Estonian dairy herds. Data consisted of 68 heifers with clinical mastitis and 995 heifers without clinical mastitis on the day of calving. Multivariable logistic regression with a random herd effect was used to investigate any association between housing system or the time interval from movement of heifers to the calving facility and day of calving on occurrence of clinical mastitis. Milk samples for bacteriological analysis were collected from affected heifers and multiparous cows on the day of calving Results Clinical mastitis occurrence in the study population of freshly calved heifers equalled 6.1 %. Housing system was not a significant risk factor for clinical mastitis of freshly calved heifers. Moving heifers to the cowbarn less than two weeks before calving in tiestall farms increased risk (OR = 5.9 p = 0.001 for clinical mastitis at parturition. The most frequently isolated udder pathogens among heifers were Escherichia coli (22.1%, Streptococcus uberis (19.1% and coagulase-negative staphylococci (8.8%. In comparison, the main pathogen in multiparous cows with clinical mastitis at parturition was Staphylococcus aureus (11.2%. Conclusion Moving heifers to the calving facilities too late in tiestall farms increased risk for clinical mastitis at parturition. The isolated udder pathogens did not differ significantly in tiestall farms compared to freestall farms in heifers, but differences were found between heifers and multiparous cows at parturition.

Full Text Available The article researches the development of Russian-language literature in Estonia through the lens of Estonian literature. The article focuses on what is conditionally referred to as “authors of the younger generation” (born in 1970 and later since the creative works of representatives of this generation have attracted a lot of attention. That is the “naughts-generation”, as the authors of this generation made their debuts in literature in the 2000s.The article views the Estonian reaction to the books of Igor Kotjuh, P. I. Filimonov and Andrei Ivanov translated into Estonian. The analysis makes use of the reception theory of Hans Robert Jauss and Wolfgang Iser, scholars from Konstanz University, which makes it possible to propose two operational hypotheses: (1 numerous reviews hint at the fact that Estonian literary journals and critics do not consider works of Estonian Russian-speaking authors to be foreign literature; (2 as works of the Russian-speaking authors of Estonia have not been represented in a single literary anthology which has appeared in the 2000s, it can be concluded that there are certain obstacles regarding the works of Russian-speaking authors in Estonia.The Russian-speaking writers of Estonia have had good co-operation with Estonian colleagues and media, since they speak Estonian and their works have continuously appeared in Estonian translations. At the same time, the Russian-speaking literature of Estonia has not become a fully valued part of Estonian literature. Three major controversies can be found in the reception, where the horizons of Estonian readers and Russian-speaking Estonian authors do not coincide:(1 Literary-theoretical controversy. Estonian literary science has always identified Estonian literature via the Estonian language, yet the Russian-speaking authors who made their debuts in the 2000s are convinced that their works are, among other things, part of Estonian literature.(2 Political.

Effect of damage on water retention and gas transport properties geo-materials: Application to geological storage of radioactive waste

International Nuclear Information System (INIS)

M'Jahad, S.

2012-01-01

In the context of geological disposal of radioactive waste, this work contributes to the characterization of the effect of diffuse damage on the water retention and gas transfer properties of concrete (CEM I and CEM V) selected by Andra, Callovo-Oxfordian argillite (host rock) and argillite / concrete interfaces. This study provides information on the concrete microstructure from Mercury porosimetry intrusion and water retention curves: each concrete has a distinct microstructure, CEM I concrete is characterized by a significant proportion of capillary pores while CEM V concrete has a large proportion of C-S-H pores. Several protocols have been developed in order to damage concrete. The damage reduces water retention capacity of CEM I concrete and increases its gas permeability. Indeed, gas breakthrough pressure decreases significantly for damaged concrete, and this regardless of the type of concrete. For argillite, the sample mass increases gradually at RH = 100%, which creates and increases damage in the material. This reduces its ability to retain water. Otherwise, water retention and gas transport properties of argillite are highly dependent of its initial water saturation, which is linked to its damage. Finally, we observed a clogging phenomenon at the argillite/concrete interfaces, which is first mechanical and then hydraulic (and probably chemical) after water injection. This reduces the gas breakthrough pressure interfaces. (author)

Two 9-year old Estonian Salix plantations suffering from dieback were studied: one situated on poor mineral soil and divided into fertilised and unfertilised plots (Saare plantation) and another growing on a well-decomposed and nitrogen-rich organic soil, without fertiliser application (Kambja plantation). Bacteria from internal tissues of visually damaged shoots from seven clones were isolated in spring and autumn. The strains were subsequently biochemically characterised and tested for ice nucleation activity and pathogenicity on Salix. Some strains were also analysed with 16S rRNA. High numbers of culturable bacteria were found, belonging mainly to Erwinia, Sphingomonas, Pseudomonas and Xanthomonas spp. Fertilised plots were significantly more colonised by bacteria than unfertilised plots and also more extensively damaged, showing a lower density of living plants after 7 years of culture. More ice nucleation active (INA) strains were found in Saare fertilised plots and at Kambja than in Saare unfertilised plots. Likewise, most pathogenic strains were isolated from Saare fertilised plots and from Kambja. For some of the willow clones studied, dieback appeared to be related to both clonal frost sensitivity and abundance of INA and pathogenic bacteria. The plantations probably suffered from the presence of high amounts of pathogens and from frost related injuries aggravated by INA bacteria. Most probably the fertilisation at Saare and the nitrogen-rich soil at Kambja created a favourable environment for bacterial development and led to high dieback levels after the first harvest.

1997-01-01

Nearly 2% of the male population of Estonia aged 20-39 years were sent to Chernobyl to assist in the cleanup activities after the reactor accident. A cohort of 4,833 cleanup workers was assembled based on multiple and independent sources of information. Information obtained from 3,704 responses to a detailed questionnaire indicated that 63% of the workers were sent to Chernobyl in 1986; 54% were of Estonian and 35% of Russian ethnicity; 72% were married, and 1,164 of their 5,392 children were conceived after the Chernobyl disaster. The workers were less educated than their counterparts than their counterparts in the general population of Estonia, and only 8.5% had attended university. Based on doses entered in workers records, the mean dose was 11 cGy, with only 1.4% over 25 cGy. Nearly 85% of the workers were sent as part of military training activities, and more than half spent in excess of 3 months in the Chernobyl area. Thirty-six percent of the workers reported having worked within the immediate vicinity of the accident site; 11.5% worked on the roofs near the damaged reactor, clearing the highly radioactive debris. The most commonly performed task was the removal and burial of topsoil (55% of the workers). Potassium iodide was given to over 18% of the men. The study design also incorporates biological indicators of exposure based on the glycophorin A mutational assay of red blood cells and chromosome translocation analyses of lymphocytes; record linkage with national cancer registry and mortality registry files to determine cancer incidence and cause-specific mortality; thyroid screening examinations with ultrasound and fine-needle biopsy; and cryopreserved white blood cells and plasma for future molecular studies. Comprehensive studies of Chernobyl cleanup workers have potential to provide a new information about cancer risks due to protracted exposures to ionizing radiation. 21 refs., 1 fig., 11 tabs

Full Text Available Service companies earn their profit mainly due to their employees’ intellectual skills, therefore, increasing profit per employee is one opportunity to increase profit and thereby also the company’s market value. In this article the number of employees, the value of owners’ equity and loan capital, operating expenses, net sales and profit before income tax have been used to analyse the change in profit per employee of the Estonian software small and medium-sized enterprise (SME sector in total, and for small and medium-sized companies separately in the years 2009–2013. Furthermore, this article demonstrates that the efficiency matrix methodology and its developments that were refined in Estonia and Russia from the 1960s to the 1990s can be deployed nowadays as well. Of all the components, profit margin and owners’ equity per employee showed the most rapid growth during the analysed period. Profit per employee was higher in the small enterprises segment and lowest among medium-sized enterprises, where owners’ equity per employee, net sales to operating expenses, and profit margin were lower than in small enterprises over the whole period analysed.

In a first part, the author recalls briefly the properties of the two argillaceous formations studied in this HDR report: the Toarcian/Domerian argillite and the Opalinus clay of Mont Terri. At first, have been described the two undamaged argillite materials and then the damaged Tournemire argillite. The second part gives the results obtained from the researches on the undamaged rock with natural tracers and with approaches using artificial tracers. The third part deals with the study of the damaged rock in separating natural perturbations of those of anthropogenic origin. At last, the conclusion gives the guiding thema of this research work and the main long-term future prospects that may result. (O.M.)

Microbial activity in argillite waste storage cells for the deep geological disposal of French bituminous medium activity long lived nuclear waste: Impact on redox reaction kinetics and potential

Micro-organisms are ubiquitous and display remarkable capabilities to adapt and survive in the most extreme environmental conditions. It has been recognized that microorganisms can survive in nuclear waste disposal facilities if the required major (P, N, K) and trace elements, a carbon and energy source as well as water are present. The space constraint is of particular interest as it has been shown that bacteria do not prosper in compacted clay. An evaluation of the different types of French medium and high level waste, in a clay-rich host rock storage environment at a depth between 500 and 600 m, has shown that the bituminous waste is the most likely candidate to accommodate significant microbial activity. The waste consists of a mixture of bitumen (source of bio-available organic matter and H2 as a consequence of its degradation and radiolysis) and nitrates and sulphates kept in a stainless steel container. The assumption, that microbes only have an impact on reaction kinetics needs to be reassessed in the case where nitrates and sulphates are present since both are known not to react at low temperatures without bacterial catalysis. The additional impact of both oxy-anions and their reduced species on redox conditions, radionuclide speciation and mobility gives this evaluation their particular relevance. Storage architecture proposes four primary waste containers positioned into armoured cement over packs and placed with others into the waste storage cell itself composed of a cement mantle enforcing the argillite host rock, the latter being characterized by an excavation damaged zone constricted both in space and in time and a pristine part of 60 m thickness. Bacterial activity within the waste and within the pristine argillite is disregarded because of the low water activity (biofilms are within the interface zones. A major restriction for the initial development of microbial colonies is the high pH controlled by the cement solution. Archea are able to survive

Iron-clay reactivity in radioactive waste disposal - Impacts of bacterial activities and heterogeneities

International Nuclear Information System (INIS)

Chautard, C.

2013-01-01

This study focuses on the interactions between two materials that may be introduced in a geological disposal of radioactive waste: metallic materials such as the high-level waste overpack, and clay materials such as the clay host rock. Indeed, the interactions between these two materials in such conditions could induce a change of their initial confinement properties. This work aimed at determining the influence of heterogeneities (technological gaps and fractures) and bacterial activities on these interactions, in terms of evolution of chemical and hydraulic properties of clayey materials. To this end, two percolation cells have been conducted during 13 months: the first one with two bacteria (SRB, IRB), the second one without bacteria. These experiments, carried out at 60 C, involved circulating synthetic water representative of the Tournemire pore water through iron powder and through Toarcian artificially cracked argillite from Tournemire. An iron rod was also placed into the argillite. Thus, solid characterizations (SEM, SEM/EDS, Raman, XRD, X-ray tomography) allowed the study of both interfaces: the iron powder/argillite interface and the iron rod/argillite interface. The water probably circulated into the crack during the entire test, which was confirmed by reactive transport modeling with the HYTEC reactive transport code. However, no secondary phase was identified in the crack. In addition, bacteria survival in the biotic cell was confirmed during the experiment by monitoring their population and by analyzing their genetic diversity at the end of the experiment. A strong decrease in sulfate concentration was measured in the output, which confirms the SRB activity. Solid characterization conducted at the end of the experiments have highlighted, with and without bacteria, the occurrence of magnetite and chukanovite in the iron powder, the latter being mainly located close to the argillite interface. In the argillite, a Fe-enriched zone (10 μm) was

The effects of political and economic transitions on health and safety in Estonia: an Estonian-Swedish comparative study.

Kaasik, T; Andersson, R; Hörte, L G

1998-11-01

A general and dramatic deterioration of health in Estonia during the transition period 1990-1994 was analysed using Sweden as a comparative example. Though there were diverging trends between Estonia and Sweden in the leading cause of death, cardiovascular diseases, the gap in mortality from injury had increased most rapidly. While the injury mortality rate slightly decreased in Sweden from 1990 to 1994, it almost doubled in Estonia. In 1994, the total injury death rate for men was about 6 times higher in Estonia than in Sweden. The death rates for some types of injuries, such as alcohol intoxication and homicide, were many tenfolds higher in Estonia than in Sweden. Injury contributed the most to the widening health gap between the countries, especially in males. The mechanisms of this sudden health deterioration remain to be fully explained. It could be hypothesised that behind the traditional behavioural risk factors, the influence of socio-political factors related to economic and political reconstruction is present. A widespread risk-taking and unhealthy behaviour among Estonians can likely be partly explained as a way of coping with the distress created by the new demands of transition society. An important challenge on the way to improvement is creating the political will among policy-makers to confront the tremendous problems of controlling the factors in society that affect the population's health in Estonia.

Full Text Available The article deals with the relationship between the literature of the Estonian diaspora in the West and Soviet Estonia during the 1960s, and explores the possibility, from the literary historiographical perspective, of integrating the two bodies of Estonian literature. Near the end of The Second World War close to 70,000 Estonians fled their homeland, fearing Soviet repression; among them were numerous members of the academic and artistic intelligentsia as well as eminent poets and writers. By the late 1940s national organizations, publications and other activities were already well underway in the displaced persons camps. During the 1950s, Estonian exiles who settled in Sweden, Canada, United States, and elsewhere in the West quickly formed national cultural centres, publishing houses and numerous organizations that helped maintain their national and cultural identity. The centre of literary activity in the West was Sweden, which most Estonian writers had chosen as their new home. The Estonian Writers’s Co-operative publishing house, established in Lund in 1950, started the mail-order distribution of Estonian literature throughout the world; elsewhere, the publisher Orto operated in Toronto. While no propaganda-free literature or literature of any artistic merit was published in the 1940s and 1950s in Estonia during the Soviet occupation, exile literature flourished. Then, the Khrushchev Thaw brought about changes to Soviet society in the late 1950s. As their world became more free, a new generation of talented young poets emerged who generated innovations in poetry and modernized literature. This article maps literary contacts between the Estonian homeland and her exiles, and, using archival material, focuses on personal contacts among the literati during the 1960s. Literary historiography began investigating the possibility of treating Estonian literature in the homeland and in the West as one body of literature, when, after a 45-year

Full Text Available The bullying at work has not so far analyzed in Estonia – its dispersal, causes and impact have not studied, while in the countries with long democratic traditions it has been the actual problem of work context for two decades. The current study examines the prevalence of workplace bullying in Estonian organizations and the extent of the problem by industries because bullying may put impact on the employees´ efficiency. The sample consists of 1941 respondents which covers 59 organizations across Estonia and represents in all over 30 000 employee and the unemployed. The results reveal that bullying poses a serious problem in Estonia. According to Leymann´s criteria (1996 at least one negative act per week with a duration of at least 6 months, has been reported by 23,44% of respondents. Although, it came out that bullying is not sector-specific problem in Estonia, several and different industries are vulnerable from bullying.

Vitamin D insufficiency and deficiency are prevalent worldwide, with the highest prevalence in the northern countries due to the lack of ultraviolet exposure. The individual effect of vitamin D on bone mineral density (BMD) has been studied but the results are inconclusive. The aim of our study was to investigate the effect of vitamin D on BMD in a random population-based cohort of Estonian adults. A cross-sectional population-based study. A total of 273 individuals free of diseases or states known to affect bone or vitamin D metabolism participated in the study. We measured BMD, vitamin D and parathyroid hormone concentrations (in winter and in summer). Several co-variables were included in the regression analysis, including age, smoking, alcohol consumption, body mass index, physical activity, fresh milk consumption, caffeinated beverage consumption, lean tissue mass and total body fat percentage, and in women the number of children and breastfeeding history. We show that summer vitamin D independently correlates with BMD in lumbar spine, trochanter and total body regions (P vitamin D predicts independently lumbar spine (P body BMD (P mass and fat mass were additional contributors of the BMD (P body composition indices, vitamin D could be an independent contributor of BMD in several skeletal regions in men and women. © 2010 The Authors.

Document available in extended abstract form only. Because of their favourable transport and retention properties, argillaceous rocks are considered as potential host rocks for radioactive waste repositories. At the request of the French Authority of Nuclear Safety (ASN), the French Institute for Radioprotection and Nuclear Safety (IRSN) is in charge of an independent expertise of the French industrial (Andra's) project. Therefore, IRSN develops experimental research programs in such geological formations at the Tournemire Underground Research Laboratory (URL, Aveyron, France). One of the objectives of this project is to evaluate the occurrence and the driving processes controlling the radionuclide migration through an argillaceous formation similar to those studied elsewhere for nuclear waste disposal. Since undisturbed argillaceous rocks display very low values for both hydraulic conductivity (K h ) and water content (θ e ), diffusion is considered to be the main transport mechanism governing radionuclide migration through the argillite. On the other hand, in the presence of fracture in the argillaceous formation, the flux of water through this preferential pathway could dramatically accelerate the migration of the radionuclide it contains. Thus, the implementation of a radwaste disposal facility requires a precise sedimentary and structural characterization of the preselected site to guarantee the presence of a regular, homogenous and fault-free clay layer over a large area and so to determine its ability to ensure an effective radionuclide confinement. The site characterization and fracture detection can be performed using complementary approaches such as geological studies, in situ measurements and non-destructive geophysical methods. In order to evaluate both the capacity and the limit of these seismic methods to detect a secondary fault in an argillaceous media, IRSN performed a 3D HR seismic survey from the surface of its Tournemire URL. Due to the weak

Kõuts, T.; Elken, J.; Raudsepp, U.

An integrated system of nested 2D and 3D hydrodynamic models together with real time forcing data asquisition is designed and set up in pre-operational mode in the Gulf of Finland and Gulf of Riga, the Baltic Sea. Along the Estonian coast, implicit time-stepping 3D models are used in the deep bays and 2D models in the shallow bays with ca 200 m horizontal grid step. Specific model setups have been verified by in situ current measurements. Optimum configuration of initial parameters has been found for certain critical locations, usually ports, oil terminals, etc. Operational system in- tegrates also section of historical database of most important hydrologic parameters in the region, allowing use of certain statistical analysis and proper setup of initial conditions for oceanographic models. There is large variety of applications for such model system, ranging from environmental impact assessment at local coastal sea pol- lution problems to forecast of offshore blue algal blooms. Most probable risk factor in the coastal sea engineering is oil pollution, therefore current operational model sys- tem has direct custom oriented output the oil spill forecast for critical locations. Oil spill module of the operational system consist the automatic weather and hydromet- ric station (distributed in real time to internet) and prognostic model of sea surface currents. System is run using last 48 hour wind data and wind forecast and estimates probable oil deposition areas on the shoreline under certain weather conditions. Cal- culated evolution of oil pollution has been compared with some real accidents in the past and there was found good agreement between model and measurements. Graphi- cal user interface of oil spill model is currently installed at location of port authorities (eg. Muuga port), so in case of accidents it could be used in real time supporting the rescue operations. In 2000 current pre-operational oceanographic model system has been sucessfully used to

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

Influence of antioxidants synthesized by plants on physico-chemical and microbiological evolution of Callovo-Oxfordian clay material

2016-01-01

This study is a part of the deep disposal site development for radioactive waste in Meuse-Haute Marne (France), most specifically on the bio-physico-chemical conversion of sedimentary clay rocks (Callovo- Oxfordian, COx), excavated and stored on surface in the form of heap. During the experimental and operational phases, several million cubic meters of argillite will be excavated. Argillite stored in the open air will be exposed to meteoritic alterations, oxidizing conditions of surface and colonized biologically (plants, bacteria, fungi). The aim of the thesis is to study the impact of naturally derived antioxidants from revegetation of heap with antioxidant-producing plants on the physical, chemical or microbial weathering processes of argillite. This work was designed to (i) identify suitable naturally derived antioxidants and the plants to produce them (ii) assess the antioxidant inhibitory effects on weathering and leaching COx metals in the laboratory, (iv) field test selected plants on the heap, (iii) follow in situ physicochemical and microbiological evolution of the argillite heap planted with antioxidant producing plants. In the laboratory, percolating model antioxidants of Lamiaceae (linalool, thymol, carvacrol) through a packed column of argillite showed variable water weathering/leaching rate depending on the metal elements present; very low for aluminum (<1 o/oo), between 1-3% for other metals (Ca, Mg, Fe...) and reach more than 60% for sodium. With thymol at 20 mg/l for 3 months, it was found that there are a decrease in sulfur leached amount and the metal elements from the sulfides (Fe, As) and carbonates (Ca, Sr) and inhibition of bacterial and fungal microflora growths. However, intake of artificial root exudates in columns stimulates microbial growth, improves the availability of aluminum, iron and provides sequestration of calcium. Among the tested plants, lavender and lavandin were selected. Two successive plantation tests were carried out in

Geochemical and palaeontological evidence for the definition of the Silurian/Devonian boundary in the Changwantang Section, Guangxi Province, China

Full Text Available Southern Guangxi Province is one of the important areas for the study of the Silurian/Devonian boundary (SDB in South China. Despite attempts to define the exact level of the SDB in the Yulin (Guangxi Province area using biostratigraphy, no consensus has been reached as the indicator fossils (e.g. graptolite Monograptus uniformis uniformis, conodont Icriodus woschmidti woschmidti and trilobite Warburgella rugulosa rugosa are not coexistent in South China. Since Mann et al. (2001: Dynamics of the Silurian/Devonian boundary sequence: sedimentary cycles vs. organic matter variation. Terra Nostra, 2001, 44–48 reported the first isotope curve based on organic carbon for the SDB at Klonk in the Czech Republic (GSSP, some comparable variation curves of δ13Corg across the SDB have been obtained at several locations including sections in Turkey and China. This distinct variation curve of the isotopic composition of organic carbon across the SDB provides a chemostratigraphic reference for a worldwide correlation of the SDB. In this study, organic geochemistry together with graptolite biostratigraphy is applied as a tool for identifying the SDB at the Changwantang Section in Yulin (Guangxi Province. The results suggest that the variations in some indexes of organic geochemistry can be correlated to the representative curve of the SDB in the Klonk and Esenyali sections. The exact level of the SDB in the Changwantang Section is positioned within the upper part of the Fangcheng Formation, which is consistent with the available palaeontological data from graptolites (e.g. Colonograptus colonus, Plectograptus sp., Monograptus uniformis, M. cf. M. praehercynicus and M. aequabilis.

Full Text Available Impelled by a desire to free themselves from the German influence that had dominated the development of Estonian literature, and from the one-sided relation of cultural dependence that had lasted several hundred years, the Young Estonia movement sought to modernize Estonian literature through borrowing from other European literatures, in particular from French, Scandinavian, and Finnish. This article seeks to clarify the relative importance and selection criteria of translations from German literature for the literary field of the Young Estonia era. Further, I seek to elucidate Young Estonia’s contribution to the renewal of these selection criteria in the first, but more importantly the second decade of the 20th century. The long list of translations from German to Estonian at the beginning of the century speaks of the ”light Muse” of German family newspapers, with an admixture of the following: naturalist light fiction with a social theme and social drama; the historical novel (great favourite of the era of historicism, trendy fiction for both feminine and masculine audiences, and an overwhelming proportion of ”Heimatskunst” (literature of local colour. In the first and second decade of the new century, new names appear on the Estonian literary scene that signal a change in taste. For example, naturalist authors (Kretzer, Hauptmann, Halbe, Dehmel crop up sporadically amidst texts meant for leisure reading. Although the first translations of Nietzsche only appeared in 1901, already in 1902 critics had reason to speak of ”Nietzsche in Estonian literature”. 1910 marked the breakthrough of Viennese modernism in the Estonian literary field (Schnitzler, Altenberg, Bahr. Under the influential protection of the Young Estonians (Suits, Kallas, and published by the Young Estonia Publishing House, Baltic German novellawriter Eduard Keyserling enters the Estonian literary scene.

Is Estonian oil shale beneficial in the future?

International Nuclear Information System (INIS)

Reinsalu, Enno

1998-01-01

Oil shale mining production reached its maximum level of 31.35·10 6 tonnes per year in 1980. After the eighties there was a steady decline in mining. The first scientific prognoses of the inescapable decrease in oil shale mining were published in 1988. According to this, the Estonian oil shale industry would vanish in the third decade of the next century. From the beginning of the nineties, the consumption and export of electricity have dropped in Estonia. The minimum level of oil shale mining was 13.5·10 6 tonnes per year. This occurred in 1994/1995. Some increase in consumption of electric power and oil shale began at the end of 1995. Oil shale processing began to increase gradually in 1993. Oil shale is the most important fuel in Estonia today. In 1997, oil shale provided 76% of Estonia's primary energy supply and accounted for 57% of its economic value. Oil shale is the cheapest fuel in Estonia. Nowadays, oil shale provides an essential part of the fuel supply in Estonia because it is considerably cheaper than other fuels. Oil shale costs EEK 12.16 per G J. At the same time, coal costs EEK 23.41 per G J and peat costs EEK 14.80 per G J (year 1997). There are three important customers of oil shale: the electric power company Eesti Energia, the oil processing company Kiviter and the factory Kunda Nordic Cement. In 1995, the power company utilised 81% of the oil shale mass and 77% of its heating value. The state energy policy inhibits increases in the oil shale price even though the mining infrastructure is decaying. Government price policies subside oil shale processing. The energy of oil shale processing is 1.9 times cheaper than the heating value of raw oil shale for power stations. It could be considered as a state subsidisation of oil and cement export at the expense of electricity. The subsidy assigned to oil processing was of EEK 124·10 6 and to the cement industry of EEK 8.4·10 6 in year 1997 (based on heating value). State regulation of prices and

The rKOA features were evaluated in the tibiofemoral joint (TFJ and patellofemoral joint. Results. The early rKOA was found in 51.4% of investigated subjects (72% women and 12.3% of participants (63% women had advanced stage of diseases. The A allele of synonymous SNP rs1044122 was associated with early rKOA in TFJ, predominantly with the presence of osteophytes in females (OR 1.57; 95% CI 1.08–2.29, . The C allele of intron polymorphism rs1871054 carried risk for advanced rKOA, mostly to osteophyte formation in TFJ in males (OR 3.03; 95% CI 1.11–7.53, . Also the CCAA haplotype of ADAM12 was associated with osteophytosis, again mostly in TFJ in males (. For rs3740199 and rs1278279, no statistically significant associations were observed. Conclusion.  ADAM12 gene variants are related to rKOA risk during the early and late stages of diseases. The genetic risk seems to be predominantly associated with the appearance of osteophytes—a marker of bone remodelling and neochondrogenesis.

The Estonian national program for sustainable resource development and its connection with teaching about fossil fuels in chemistry courses

Karik, H.

1996-01-01

The conception of sustainable resource development worked out under the initiative of the United Nations (UN) actualizes ideas for improving the health of people and the environment. The needs of people are to he addressed and, simultaneously, natural resources preserved. That is ,why ecological and economic expenses are to he integrated and flow sheets of industrial plants are to be reorganized in order to utilize natural resources in a rational way. The association of Estonia with the resolution of the UN Conference on Environmental Development held in Rio de Janeiro and the resolution of the Estonian Parliament concerning The National Program of Sustainable Development require changes in our lifestyle. Chemical education in schools has to support a change in the way of thinking and many concrete subjects can be connected with the problems of sustainable development. Metallic elements get into the environment mostly with fuel combustion ashes. According to various prognoses, fossil fuel resources will last for a thousand years. This means that more and more metallic compounds are thrown into the environment. Dispersion of metals in the air, water bodies and soil is continuously increasing. Finally, they reach the food chain and to the human body. As a result, toxicosis, illnesses, and inadvisable dislocations in organic life may occur. The trend to use ash as a raw material for metal production is considered to have some prospective economically attractive application. This would be one possible way of sustainable resource development to avoid the increase of environmental pollution and increase production of the corresponding metals

To explore smoking prevalence and attitudes towards smoking among Estonian physicians in 2002 and 2014. Two self-administered cross-sectional postal surveys were conducted among practising physicians in Estonia. Initial sample consisted of all practising physicians in Estonia. The corrected response rate was 67.8% in 2002 and 53.1% in 2014. Present study sample was restricted to physicians younger than 65 years (n=2549 in 2002, n=2339 in 2014). Age-standardised prevalence of smoking and prevalence of agreement with seven statements concerning attitudes towards smoking was determined. To analyse association of physicians' attitudes towards smoking with study year and smoking status, logistic regression analysis was used. Adjusted ORs of agreement with the seven statements were determined. Corresponding 95% CIs were calculated. The age-standardised prevalence of current smoking among men was 26.8% in 2002 and 15.3% in 2014, among women 10.4% and 5.8%, respectively. Compared with the year 2002, in 2014, prevalence of agreement with statements declaring harmfulness of smoking was higher and prevalence of agreement with statements approving smoking was lower. Adjusted ORs showed that compared with 2002, physicians' attitudes towards smoking were less favourable in 2014, and physicians' attitudes towards smoking were associated with their smoking status. Compared with 2002, the age-standardised smoking prevalence among male and female physicians was lower, and attitudes towards smoking were less approving in 2014. The smoking physicians had more approving attitudes towards smoking than their non-smoking colleagues. © Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2017.

Eeskätt on see seotud Evald Hermaküla, Jaan Toominga, Kalju Komissarovi, Kaarin Raidi jt nimedega. Noor režissuur tõstis mässu ahtaks muutunud realismi raamide vastu, mis ei vastanud noore põlvkonna teatriootustele. Olles mõjutatud ideeliselt radikaalsest eksperimentaalteatrist USAs, aga ka Jerzy Grotowski katsetustest ning teistest avangardsetest liikumistest, muutis see füüsilist teatrikeelt. Tõusis improvisatsiooni osakaal. Teater lakkas olemast dramaturgiliste tekstide esituskoht, vaid hakkas otsima etendustes vahetut kohalolu. Tajuprotsessi hakkas juhtima mängu põhimõte. Suured müüdid dekonstrueeriti, autoritaarsusele vastanduti. Seksuaalsus ilmutas end uuel jõul, toetatud alateadvuse impulssidest. Uue laine radikaalsus kestis 1970. aastate lõpuni, mil see sulandus peavoolu. Murrang teatriesteetikas mõjutas kogu järgnenud teatriperioodi, seda on kutsutud ka eesti teatri kuldajaks. SU M M A R Y Young directors emerged in Estonian theatre at the end of the 1960s. More specifically, during the years 1969–1974 many new directors’ names appeared on theatre posters, and the fundamental changes in the language and content of the theatre at the end of the 1960s and the 1970s began to be associated with these names. Most important among these are Evald Hermaküla, Jaan Tooming, Kalju Komissarov, and Karin Raid. Within a short time these young directors changed prevailing assumptions about the purpose, means, and content of the theatre in Estonia. This phenomenon came to be referred to as the breakthrough, or the new wave; later on, in sum, as the renewal of theatre. A generational change was taking place in the theatre, and in this framework a different language of theatre emerged, which began carrying innovative emotional and aesthetic paradigms.

Full Text Available As an important chapter of Estonian literary history, Young Estonia has been relatively well researched and interpreted. However, its influence as a cultural and intellectual movement in Estonian society in the opening decades of the last century requires further study and verification. What stands reflected in Young Estonia is actually a larger groundswell of history, along with a rupture that took place throughout Estonian society in the course of its modernization. Discussions of the meaning of Young Estonia must therefore concern themselves with literary discourse, but much more so with what transpired outside the boundaries of literary pursuits, in the contexts of social and political history and the history of ideas. In view of historiography, there is no consensus on the definition of Young Estonia: it has been referred to as a movement, a group, or a cluster of seminal ideas. The founding of the group is generally located at the publication of the first Young Estonia album near the high tide of the Russian Revolution of 1905. Young Estonia disintegrated during the First World War, with its ending marked both by the publication of the fifth and final album in 1915 and by the journal Vaba Sõna (Free Word, which carried on the ideology of Young Estonia in the years 1914–1916. Although there are strong parallels between Young Estonia and similar movements and associations in Western and Central Europe in the nineteenth century, the greatest influence being exerted by the politicalliterary movement Nuori-Suomi (Young Finland, the respective group in Estonia was largely autochthonic in its time and milieu. In the rhetoric of the era of national awakening, Baltic Germans referred to Estonian national activists as ”Young Estonians”; the term was also under discussion in the Estonian press, yet there is no direct conceptual connection between this polemic and Young Estonia as a group. The Young Estonia group was mostly composed of young

Experimental study and modelling of physico-chemical mechanisms of clay-concrete interactions in the radioactive waste geological disposal context

International Nuclear Information System (INIS)

Dauzeres, A.

2010-09-01

These research works are carried out as part of the radioactive wastes geological disposal feasibility study. The current option developed by Andra, includes several cementitious materials in contact with the surrounding Callovo-Oxfordian (COX) (an argillite). Concretes and argillite present very different pore solutions (ionic concentrations and pH). Controlled by the concentrations differences, the aqueous species diffusion in the solids generates chemical and physical disturbances. This study is based on experimental, analytical and numerical works, in order to identify the mechanisms controlling the clayey environment influence on cementitious materials. (author)

Mineralogical evolution of argilites in dehydrated-oxidised zones: the example of the argilitic walls from Tournemire tunnel

International Nuclear Information System (INIS)

Charpentier, D.; Cathelineau, M.; Mosser-Ruck, R.; Bruno, G.

2001-01-01

Digging of underground work such as that of the Tournemire tunnel in a Toarcian argillite formation, has an impact on the surface mineralogy of the rock blocks. In spite of its very low water content, the argillite is reactive as a consequence of the modification of the redox conditions. Thus, atmospheric oxygen in presence of adsorbed water induces pyrite corrosion and formation of secondary mineral phases such as gypsum, celestite, jarosite and Fe-hydroxides, which play a significant role on the water-rock equilibria of the mechanically disturbed zone.

PHREEQC integrated modelling of plutonium migration from alpha ILL radwaste: organic complexes, concrete degradation and alkaline plume

International Nuclear Information System (INIS)

Cochepin, B.; Munier, I.; Giffaut, E.; Grive, M.

2010-01-01

Document available in extended abstract form only. The effects of organic compounds derived from Long-Lived Intermediate-Level waste (LLILW) degradation need to be precisely described regarding the radionuclide migration in storage cells and argillites. These evaluations play a major role in the final decision for accepting these waste products in the future storage facility. The evaluation process engaged by Andra implies the use of coupled chemical transport tools able to take into account the linking of processes occurring in storage conditions as well as the different cell components (containers, packages, lining...). The relevance of this approach must fundamentally be based on a consistent characterization concerning (i) the waste packages, (ii) their degradation products (nature and kinetics), (iii) the chemical evolution of these products in the storage disposal (for cement material particularly) and in the argillites, and (iv) the correlation with the radionuclide behavior regarding to these sequestering agents (chemistry and transport). Andra is now involved in an internal evaluation of technological organic waste packages contaminated by plutonium coming from the MOX fuel plant called MELOX located at Marcoule (France), considering the consistent work undertaken to characterize these organic agents. This evaluation is based on an integrated representation in terms of chemical processes and transport of the concrete chemical degradation (e.g. waste packages, backfill and lining), the alkaline plume in the near field of argillites and the plutonium-organic complexes. The conceptual model is based on the following assessments: On the chemical aspect: (i) Both concrete and argillites undertake chemical perturbations with dissolution/precipitation, ion exchanges, surface and aqueous complexation. (ii) The degradation products of the MELOX waste organic compounds are limited to five major organic acids: iso-saccharinic (ISA), acetic, phtalic, adipic and

This report describes the final results of Task C of the international DECOVALEX-THMC project devoted to Excavation Damaged Zone (EDZ) in argillaceous rock at the Tounemire site in France. Task C is aimed to develop adequate numerical models for interpretation of observed damaged zones around three openings excavated at different times. The research teams are asked to model the evolution of the EDZ with time and to compare their results with measurements that were performed at the site. The main objective is to investigate the hydro-mechanical behavior of Tounemire argillite around the three openings (1881 tunnel, 1996 gallery, 2003 gallery) of Tournemire site. The work was divided into 3 parts: 1. Modelling of the unsaturated zones around the three openings; 2. Modelling of the mine-by-test experiment around the 2003 gallery; 3. EDZ modeling around the 3 openings. Each research team has performed its own HM numerical calculations based on the principal following considerations: The hydraulic time dependent boundary condition at each opening wall was calculated by the Kelvin equation using the provided humidities and temperatures; The effective stress approach of partially saturated medium was used; The swelling-shrinkage of Tournemire argillite was taken into account; The capillary pressure curve was assumed to be given by the Van Genuchten relation and calibrated from the provided data of the two successful laboratory tests; The influence of the degree of saturation on liquid water permeability was modelled using a relative permeability function which is based also on the Van Genuchten model; The intrinsic permeability was calibrated in order to get a better fit with experimental data. To achieve the first objective, the three research teams act as follows: 2D HM coupled simulations have been undertaken by ISEB-BGR team. Hydraulic and mechanical anisotropies were considered; 2D HM coupled simulations have been also undertaken by CEA-IRSN team. Only mechanical

Recent prospective studies of male reproductive health have shown differences between several European countries. Our objective was to evaluate the current situation in the two Baltic States Estonia and Lithuania. In 1997-99 we investigated semen parameters, levels of reproductive hormones and general health factors of 196 men from the general population in Lithuania; from Estonia, 79 men from the general population and 118 soldiers were investigated. Adjusted for interlaboratory differences and abstinence period, sperm concentration of Lithuanian and Estonian men from the general populations were shown to be 55 and 67 million/mL, respectively. The Estonian soldiers had the highest sperm concentration, 82 million/mL. The frequencies of morphologically normal spermatozoa were 6.2, 7.7 and 9.6%, respectively. In contrast to the semen qualities, highest Inhibin B levels were detected in the Lithuanians (233 pg/mL) followed by Estonian men from the general population (220 pg/mL) and Estonian soldiers (185 pg/mL). The soldiers had also the lowest level of testosterone and oestradiol. The sperm counts of the Estonian and Lithuanian men investigated here are higher than recently shown for Norwegian, Danish, Estonian and Finnish men. Comparisons should be cautiously drawn as the groups are not completely comparable. Still, even within the Baltic region, geographically close and sharing common recent social history, differences in semen quality and levels of reproductive hormones are apparent.

A gravity and magnetic study of the Syncline Ridge area was conducted as part of an investigation of argillite rocks of the Eleana Formation under consideration as a medium for the possible storage of high-level radioactive waste. Bouguer gravity anomaly, low-level aeromagnetic anomaly, density, and magnetization data collectively indicate the following, relative to the Eleana Formation, the principal target of the investigation: (1) in an area extending northwestward from Mine Mountain, through Syncline Ridge, to the Eleana Range, the Eleana Formation, where not exposed, occurs at depths of less than approx. 200 m, except for a small region of exposed older Paleozoic rocks; (2) in the region of shallowly buried Eleana Formation, occurrences of volcanic rock cover are delineated by low-level aeromagnetic anomaly data, which also discriminate normally polarized from reversely polarized tuff units; and (3) selective detection of high-quartz argillite relative to low-quartz argillite using surface gravity data is not feasible if the high-quartz and low-quartz varieties are intimately interbedded, as observed in boreholes. 4 figures, 2 tables

Kollo, Karin; Kall, Tarmo; Liibusk, Aive

GNSS permanent station network in Estonia (ESTREF) was established already in 2007. In 2014-15 extensive reconstruction of ESTREF was carried out, including the establishment of 18 new stations, change of the hardware in CORS stations as well as establishing GNSS-RTK service for the whole Estonia. For GNSS-RTK service one needs precise coordinates in well-defined reference frame, i.e., ETRS89. For long time stability of stations and time-series analysis the re-processing of Estonian CORS data is ongoing. We re-process data from 2007 until 2015 with program Bernese GNSS 5.2 (Dach, 2015). For the set of ESTREF stations established in 2007, we perform as well computations with GIPSY 6.4 software (Ries et al., 2015). In the computations daily GPS-only solution was used. For precise orbits, final products from CODE (CODE analysis centre at the Astronomical Institute of the University of Bern) and JPL (Jet Propulsion Laboratory) for Bernese and GIPSY solutions were used, respectively. The cut-off angle was set to 10 degrees in order to avoid near-field multipath influence. In GIPSY, precise point positioning method with fixing ambiguities was used. Bernese calculations were performed based on double difference processing. Antenna phase centers were modelled based on igs08.atx and epnc_08.atx files. Vienna mapping function was used for mapping tropospheric delays. For the GIPSY solution, the higher order ionospheric term was modelled based on IRI-2012b model. For the Bernese solution higher order ionospheric term was neglected. FES2004 ocean tide loading model was used for the both computation strategies. As a result, two solutions using different scientific GNSS computation programs were obtained. The results from Bernese and GIPSY solutions were compared, using station repeatability values, RMS and coordinate differences.

Temporal and spatial variability of Fe and Mn in perched groundwater flowing through weathered argillite underlying a steep forested hillslope

Science.gov (United States)

Kim, H.; Bishop, J. K.

2013-12-01

Groundwater flowing through weathered bedrock dictates the runoff chemistry to streams in many catchments yet; its chemical evolution has been rarely documented. In particular, observations of Fe and Mn dynamics in groundwater are extremely challenging due to their high reactivity. To preserve the sample integrity for these elements we have developed a new sampling scheme that is applicable to autosamplers; a gravitational filtration system (GFS). GFS is capable of filtering samples by gravity within 30 minutes after the sampling. The GFS samples showed a good agreement with reference samples, which were collected following the standard sampling method for trace metals (i.e. immediate filtration and acidification). Since October 2011, GFS has been employed to monitor Fe and Mn in perched groundwater that moves through weathered argillite in an intensively instrumented hillslope (Rivendell), in the Angelo Coast Range Reserve. The study site is located at the headwaters of the Eel River, northern California, characterized by a typical coastal Californian Mediterranean climate. We collected groundwater samples at 3 wells along the hillslope (upslope (W10), mid-slope (W3) and near the creek (W1)) with 1-3 day intervals. Additionally, rainwater and throughfall samples were collected at a meadow near the hillslope and at the middle of the hillslope, respectively. The results from our observations indicate that Fe and Mn exhibit distinct spatial and temporal behavior under variable hydrologic conditions. The concentrations of Fe in throughfall vs. rainwater were similar (0.45μM vs. 0.49μM), but Mn in throughfall was 10-fold higher than that in rainwater (1.2 μM vs. 0.1 μM). In the early rainy season, W10's water table was deep (-18m) and Fe and Mn in W10 were 30-150 nM and 1-2 μM, respectively. As the rainy season proceeds, W10's water table rose by 4-6m, indicating the arrival of new water. At this time, Mn in W10 decreased to ~0.1 μM, synchronizing with the water

Full Text Available Abstract Background Hereditary spastic paraplegia (HSP is a clinically and genetically heterogeneous disorder that can be an autosomal-dominant, autosomal-recessive, or X-linked disease. The most common autosomal-dominant form of the disease derives from mutations in the SPAST gene. Methods The aim of this study was to analyze 49 patients diagnosed with HSP from the Estonian population for sequence variants of the SPAST gene and to describe the associated phenotypes. Healthy control individuals (n = 100 with no family history of HSP were also analyzed. All patient samples were screened using denaturing high performance liquid chromatography (DHPLC and multiplex ligation-dependent probe amplification (MLPA assay. Samples with abnormal DHPLC and MLPA profiles were sequenced, with the same regions sequenced in control samples. Results Sequence variants of SPAST were identified in 19/49 HSP patients (38.8%, twelve among them had pathogenic mutations. Within the latter group there was one sporadic case. Eight patients had pure, and four - complex HSP. The twelve variants were identified: seven pathogenic (c.1174-1G>C, c.1185delA, c.1276C>T, c.1352_1356delGAGAA, c.1378C>A, c.1518_1519insTC, c.1841_1842insA and five non-pathogenic (c.131C>T, c.484G>A, c.685A>G, c.1245+202delG, c.1245+215G>C. Only 2 of these mutations had previously been described (c.131C>T, c.1245+202delG. Three mutations, c.1174-1G>C, c.1276 C>T, c.1378C>A, showed intrafamilial segregation. Conclusion This study identified new variants of the SPAST gene which included benign missense variants and short insertions/deletions. No large rearrangements were found. Based on these data, 7 new pathogenic variants of HSP are associated with clinical phenotypes.

On the lower boundary of the Floian Stage in Estonia

Directory of Open Access Journals (Sweden)

Helje Pärnaste

2012-11-01

Full Text Available The lower boundary of the Second Stage of the Lower Ordovician Series, the Floian Stage, is defined by the first appearance of the graptolite Tetragraptus approximatus. In the stratotype section of Diabasbrottet at Hunneberg, southern Sweden, the boundary falls within the Megistaspis planilimbata trilobite Zone and within the Oelandodus elongatus–Acodus deltatus deltatus conodont Subzone of the Paroistodus proteus Zone, and within the Hunneberg Regional Stage. Graptolites, including the index species T. approximatus, are missing in the terrigenous sediment of Estonia. The earliest trilobites are poorly preserved in this terrigenous succession. They represent an interval older than the Megalaspides dalecarlicus Zone but probably younger than the M. planilimbata Zone, and are correlative to the Prioniodus elegans conodont Zone. Thus the lower boundary of the Second Stage can be detected using mainly conodonts. In accordance with conodont occurrence, the base of the Floian (i.e. somewhat higher than the base of the O. elongatus–A. d. deltatus Subzone falls within the Joa Member of the Leetse Formation. Probable levels have been suggested in some localities. Thus the lower part of the Leetse Formation belongs to the Tremadoc Stage, and to the Hunneberg Regional Stage.

One Country, Two Polarised Audiences: Estonia and the Deficiency of the Audiovisual Media Services Directive

Directory of Open Access Journals (Sweden)

Andres Jõesaar

2015-12-01

Full Text Available This article argues that until recent times, the Estonian media policy has mainly been interpreted as an economic issue and it did not account for the strategic need to build a comprehensive media field to serve all groups in society. This has happened despite the fact the Estonian media policy is in line with the European Union (EU media policy, which should ensure freedom of information, diversity of opinion and media pluralism. Findings of the Estonian case study show that despite these noble aims, Estonia has two radically different information fields: one for Estonian speaking audiences and one for Russian speakers. Events in Ukraine have added to the democratic media policy paradigm a question of national security. Now it is a challenge for the policy makers to unite polarised media fields and how to minimise the impact of Russian propaganda. On the EU level, one supportive measure could be a revision of the Audiovisual Media Service Directive.

Exports of company: SWOT-analysis, product strategy and sales targets

International Nuclear Information System (INIS)

1998-01-01

Despite its smallness Estonia has a good chance to enjoy a success in the international peat market, due to the favourable geographical location and well developed peat industry. There are numerous harbours, low wages and salaries, and a good educational background in Estonia. Moreover, Estonian economy is aiming at a competitive market economy. Peat exports represent a great opportunity to improve the balance of payments, create jobs, support the State through the taxes paid, meet the needs of foreign customers, earn a profit for Estonian peat companies and better Estonian standard of living. When preparing this paper, marketing textbooks and professional articles of interest were used. The working experience of one of Estonian peat companies and acquired practical knowledge have also been of help throughout the thesis. In general, it may be expected that Estonian peat exports will increase in the next few years. The Netherlands and Germany will remain the main target countries, also France, Belgium and the United Kingdom are important. The exports to Italy will, for sure, increase, to the Middle-East these will be quite likely. The Far East is also a potential market, especially Korea and Japan. Peat marketing is based on the following premises: the demand for peat is a derived demand, being dependent on that for the end-products. The number of customers is small and their decisions are rational. Estonian peat producers also have to face the fact that the production needs to be marketed mostly abroad. While considering the product strategy, the conclusion was that with peat the least cost strategy is easily applicable. Possibilities for differentiation are almost next to nothing (except in case of packaging or transportation services). Possibilities will widen when the production of potting soils is launched. Most Estonian peat firms sell peat and products thereof through foreign wholesalers, some of them render also transportation services and this is well

Full Text Available Preservation of national cultural heritage has been during the last years actively discussed both on institutional and state levels. In October 2003 the working group on digital preservation by theMinistry of Culture elaborated preservation guidelines Strategy of digital preservation of Estonian cultural heritage for years 2004–2007. The strategy is based on the principles of eEurope 2002Action Plan (2000 and Lund Principles (2001.The state strategy is aimed to achieve collaboration of different memory institutions in order to elaborate an unified view on cultural heritage and its digitisation as well as to preservation of digitally created cultural heritage. It is also important to guarantee preservation of cultural heritage and to make it accessible to the public use through the contemporary possibilities of informationand communication technologies. Digitisation and preservation of digitized heritage will be coordinated by the state. The main coordinators are the Ministry of Culture, The Ministry of Educationand Science, the State Chancellery and the National Archive.The methodology of decision making for digital preservation is based on the principles of the UNESCO programme Memory of the World. The choice of objects for digitisation is based on need and expediency that can be evaluated on the ground of acultural value of an object, conservation risks, physical condition of an object and necessity of use.In 2004–2005 metadata requirements for digital preservation were elaborated. The guidelines foresee that digitized objects will be described by four categories of metadata: administrative andtechnical metadata, metadata on access inhibitors and restrictions of use and descriptive metadata. Estonian documentary heritage is located today in different memory institutions: in state or public institutions like archives, libraries and museums, in private possession, in religious and scientific institutions and in possession of the third sector

associated calcareous metaturbidites of Ordovician age as well as shallow-water Silurian dolostones. Scattered metacarbonate rocks are chiefly Cambrian, Ordovician, Silurian, and Devonian dolostones that formed in shallow, warm-water settings with locally restricted circulation and marbles of less constrained Paleozoic age. Carbonate metaturbidites occur on the northeast and southeast coasts and yield mainly Silurian and lesser Ordovician and Devonian conodonts; the northern succession also includes debris flows with meter-scale clasts and an argillite interval with Late Ordovician graptolites and lenses of radiolarian chert. Mafic igneous rocks at least partly of Early Devonian age are common in the southern succession. Carbonate rocks on Seward Peninsula experienced a range of deformational and thermal histories equivalent to those documented in the Brooks Range. Conodont color alteration indices (CAIs) from Seward Peninsula, like those from the Brooks Range, define distinct thermal provinces that likely reflect structural burial. Penetratively deformed high-pressure metamorphic rocks of the Nome Complex (CAIs ≥5) correspond to rocks of the Schist belt in the southern Brooks Range; both record subduction during early stages of the Jurassic–Cretaceous Brooks Range orogeny. Weakly metamorphosed to unmetamorphosed strata of the York terrane (CAIs mainly 2–5), like Brooks Range rocks in the Central belt and structural allochthons to the north, experienced moderate to shallow burial during the main phase of the Brooks Range orogeny. The nature of the contact between the York terrane and the Nome Complex is uncertain; it may be a thrust fault, an extensional surface, or a thrust fault later reactivated as an extensional fault. Lithofacies and biofacies data indicate that, in spite of their divergent Mesozoic histories, rocks of the York terrane and protoliths of the Nome Complex formed as part of the same lower Paleozoic carbonate platform.

Estonia is among the countries who signed the Framework Convention on Climate Change (FCCC) at the UN Conference in Rio de Janeiro in June 1992. The FCCC calls on its parties to inventory national sources, to reduction in greenhouse gases and to development of projects responding to climate change. In 1994, an Estonian Country Study Project was initiated within the U.S. Country Studies Program. The Estonian Country Study Project is comprehensive, covering all sectors and directions of activity in Estonia that might impact climate change or be influenced by Global Climate Change. This book contains a collection of papers, covering the aims of the Estonian Country Study Project

The objective was to compare the relationships between luteal activity and fertility, and relate these parameters to metabolic indices and body condition changes in multiparous Estonian Holstein cows on two commercial dairy farms under different management and levels of production and nutrition (higher, H, n=54 (71 lactations) and lower, L, n=39 (39 lactations)). For statistical analysis cows were categorized according to their milk progesterone (P4) profiles as follows: normal ovarian function; delayed start of cyclicity (DC) (interval from calving to first luteal response (P45 ng/ml up to and more than 50 d respectively, followed by regular cyclicity); cessation of luteal activity (prolonged interluteal interval, P4bodies, non-esterified fatty acids, total cholesterol) and aspartate aminotransferase, body condition scores (BCS) and fertility parameters between the two farms, and also fertility parameters between the farms within P4 categories. Differences in milk fat/protein ratio, ketone body levels and BCS indicated a deeper negative energy balance (NEB) during the first month after calving on farm L. On both farms nearly 50% of the recently calved dairy cows suffered from ovarian dysfunction during the post-partum period. Delayed start of cyclicity was the most prevalent abnormal P4 profile, 25% and 28% on farms H and L, respectively. Prolonged luteal activity accounted for one-third of atypical ovarian patterns on farm H, and cessation of luteal activity on farm L. On farm L, DC cows had lower BCS values from day 10 to day 90 after calving compared with normal cows (Pcows lost more BCS (1.2 units) during the 40 d after calving than normal resumption cows (0.75 units; P<0.05). On farm H with moderate NEB the delayed start of ovulation post partum did not impair subsequent reproductive performance.

Full Text Available The basic parameters of extra-tropical cyclones in the northern Baltic are examined in relation to extreme sea level events at Estonian coastal stations between 1948 and 2010. The hypothesis that extreme sea level events might be caused not by one intense extra-tropical cyclone, as suggested by earlier researchers, but by the temporal clustering of cyclones in a certain trajectory corridor, is tested. More detailed analysis of atmospheric conditions at the time of the two most extreme cases support this concept: the sequence of 5 cyclones building up the extreme sea level within about 10 days was very similar in structure and periodicity.

Abortion trends from 1996 to 2011 in Estonia: special emphasis on repeat abortion

Science.gov (United States)

2014-01-01

Background The study aimed to describe the overall and age-specific trends of induced abortions from 1996 to 2011 with an emphasis on socio-demographic characteristics and contraceptive use of women having had repeat abortions in Estonia. Methods Data were retrieved from the Estonian Medical Birth and Abortion Registry and Statistics Estonia. Total induced abortion numbers, rates, ratios and age-specific rates are presented for 1996–2011. The percentage change in the number of repeat abortions within selected socio-demographic subgroups, contraception use and distribution of induced abortions among Estonians and non-Estonians for the first, second, third, fourth and subsequent abortions were calculated for the periods 1996–2003 and 2004–2011. Results Observed trends over the 16-year study period indicated a considerable decline in induced abortions with a reduction in abortion rate of 57.1%, which was mainly attributed to younger cohorts. The percentage of women undergoing repeat abortions fell steadily from 63.8% during 1996–2003 to 58.0% during 2004–2011. The percentage of women undergoing repeat abortions significantly decreased over the 16 years within all selected socio-demographic subgroups except among women with low educational attainment and students. Within each time period, a greater percentage of non-Estonians than Estonians underwent repeat abortions and obtained third and subsequent abortions. Most women did not use any contraceptive method prior to their first or subsequent abortion. Conclusion A high percentage of women obtaining repeat abortions reflects a high historical abortion rate. If current trends continue, a rapid decline in repeat abortions may be predicted. To decrease the burden of sexual ill health, routine contraceptive counselling, as standard care in the abortion process, should be seriously addressed with an emphasis on those groups - non-Estonians, women with lower educational attainment, students and women with children

The role of gender, values, and culture in adolescent bystanders' strategies.

We examined the relationship between adolescent bystanders' strategies for intervening in the bullying-like situation and their gender, values, and cultural origin. The sample consisted of 682 Estonian and Russian-Estonian adolescents (M age = 13.02 years). They were shown a video of a bullying-like situation with a non-intervening adult bystander and asked to describe what they would do if they, instead of the adult, witnessed that situation. Only 10% said that they would not intervene. Girls were more likely than boys to suggest multiple actions. Adolescents who valued conformity were less likely to propose using physical aggression. Doing nothing was less likely suggested by those who placed more importance on conformity and less on power. Estonian adolescents were more likely than their Russian-Estonian peers to suggest finding out what is going on, and less likely to say that they would do nothing. The findings suggest that although most adolescents express willingness to help the victim, they might not actually know how to intervene. © The Author(s) 2014.

Selection of areas for testing in the Eleana formation: Paleozoic geology of western Yucca Flat

Energy Technology Data Exchange (ETDEWEB)

Sweeney, J J

1984-07-01

The Paleozoic geology of NTS is reviewed to select an area for underground nuclear testing in shale. Constraints on possible areas, dictated by test program requirements and economics, are areas with topographic slope less than 5/sup 0/, depths to working point less than 3000 ft., and working points above the water table. The rock formation selected is Unit J (argillite) of the Mississippian age Eleana Formation. Within NTS, Western Yucca Flat is selected as the best area to meet the requirements. Details of the Paleozoic structure of western Yucca Flat are presented. The interpretation is based on published maps, cross-sections, and reports as well as borehole, refraction seismic, and gravity data. In terms of subsurface structure and areas where Eleana Formation Unit J occurs at depths between 500 ft to 3000 ft, four possible testing areas are identified. The areas are designated here as A, B, C and the Gravity High. Available data on the water table (static water level) is reviewed for western Yucca Flat area. Depth to the water table increases from 500 to 600 ft in Area A to 1500 ft or more in the Gravity High area. Review of the water table data rules out area A and B for testing in argillite above the water table. Area C is relatively unexplored and water conditions are unknown there. Thus, the Gravity High is selected as the most promising area for selecting testing sites. There is a dolomite thrust sheet of unknown thickness overlying the argillite in the Gravity High area. An exploration program is proposed to better characterize this structure. Finally, recommendations are made for procedures to follow for eventual site characterization of a testing site in argillite. 22 references, 12 figures, 1 table.

Impact of chemical oxidation and water acidification on the mineralogical and physico-chemical properties of the Tournemire argillaceous formation

Charpentier, D.

2001-11-01

The French Institute for Protection and Nuclear Safety (IPSN) has selected a site near Tournemire (France) for research programmes on deep geological waste disposal in clay-rich rock formation. A railway tunnel was built about 100 years ago through the thick indurated Toarcian argillite of the Tournemire Massif and two galleries were constructed five years ago. They are used to study the evolution of rock mineralogical composition, texture, water content and water-rock interactions in the excavated disturbed zone. Multi-scale and multi-technique investigations were carried out on the evolution of physical and mineralogical rock properties. Experiments and numerical modelling were used to predict changes due to water-rock interactions and subsequent rock mineralogy and water chemistry modifications. The argillite consists of detrital clay-rich layers and carbonate layers. Pyrites are always present in significant amounts (2 to 2.5 %). The rock presents very low porosity and very low water content (around 3 %). Leaching experiments show that the interstitial water is Na and SO 4 -rich and Cl-poor. The tunnel and galleries digging induces fracture formation. In the altered samples, the clay particles show a better orientation in the stratification plan, which increases the porosity. The oxidation effect yields to mineralogical transformation on the surfaces of the argillite: oxidation of pyrite, dissolution of calcite, dissolution of illite layers in interstratified I/S and formation of gypsum, Fe-oxi/hydroxides, celestite and jarosite. During cycles of hydration/dehydration, condensation water interacts with the argillite and quickly becomes Ca and SO 4 -rich. The local dissolution of clay particles leads to an increase of the chloride and potassium water content. These phenomena are important for the consideration of the underground work stability, especially the evolution of the water-rock equilibria during the re-hydration of the excavated disturbed zones.

Radioactive waste disposal in shale/argillite rock formations has been widely considered given its desirable isolation properties (low permeability), geochemically reduced conditions, anomalous groundwater pressures, and widespread geologic occurrence. Clay/shale rock formations are characterized by their high content of clay minerals such as smectites and illites where diffusive transport and chemisorption phenomena predominate. These, in addition to low permeability, are key attributes of shale to impede radionuclide mobility. Shale host-media has been comprehensively studied in international nuclear waste repository programs as part of underground research laboratories (URLs) programs in Switzerland, France, Belgium, and Japan. These investigations, in some cases a decade or more long, have produced a large but fundamental body of information spanning from site characterization data (geological, hydrogeological, geochemical, geomechanical) to controlled experiments on the engineered barrier system (EBS) (barrier clay and seals materials). Evaluation of nuclear waste disposal in shale formations in the USA was conducted in the late 70’s and mid 80’s. Most of these studies evaluated the potential for shale to host a nuclear waste repository but not at the programmatic level of URLs in international repository programs. This report covers various R&D work and capabilities relevant to disposal of heat-generating nuclear waste in shale/argillite media. Integration and cross-fertilization of these capabilities will be utilized in the development and implementation of the shale/argillite reference case planned for FY15. Disposal R&D activities under the UFDC in the past few years have produced state-of-the-art modeling capabilities for coupled Thermal-Hydrological-Mechanical-Chemical (THMC), used fuel degradation (source term), and thermodynamic modeling and database development to evaluate generic disposal concepts. The THMC models have been developed for shale

Full Text Available Abstract Background For postmenopausal women, the main reason to start hormone therapy (HT is to reduce menopausal symptoms and to improve quality of life (QOL. The aim of this study was to analyse the impact of HT on different aspects of symptom experience and QOL during a randomised trial. A total of 1823 postmenopausal women were recruited into the Estonian Postmenopausal Hormone Therapy (EPHT trial in 1999–2001. Women were randomised to blind HT, open-label HT, placebo or non-treatment arm. After one year in the trial, a questionnaire was mailed and 1359 women (75% responded, 686 in the HT arms and 673 in the non-HT arms. Mean age at filling in the questionnaire was 59.8 years. The questionnaire included Women's Health Questionnaire (WHQ to assess menopause specific QOL of middle-aged women together with a 17-item questionnaire on symptoms related to menopause, a question about painful intercourse, and a question about women's self-rated health. Results After one year in the trial, fewer women in the HT arms reported hot flashes, trouble sleeping, and sweating on the symptom questionnaire. According to WHQ, women in the HT arms had fewer vasomotor symptoms, sleep problems, and problems with sexual behaviour, but more menstrual symptoms; HT had no effect on depression, somatic symptoms, memory, attractiveness, or anxiety. A smaller proportion of women reported painful intercourse in the HT arms. There were no significant differences between the trial arms in women’s self-rated subjective health. Conclusions The results from the EPHT trial confirm that HT is not justified for treating symptoms, other than vasomotor symptoms, among postmenopausal women. WHQ proved to be a useful and sensitive tool to assess QOL in this age group of women.

Estonian soil classification (ESC) has been used successfully during more than half of century in soil survey, teaching of soil science, generalization of soil databases, arrangement of soils sustainable management and others. The Estonian normally developed (postlithogenic) mineral soils (form 72.4% from total area) are characterized by mean of genetic-functional schema, where the pedo-ecological position of soils (ie. location among other soils) is given by means of three scalars: (i) 8 stage lithic-genetic scalar (from rendzina to podzols) separates soils each from other by parent material, lithic properties, calcareousness, character of soil processes and others, (ii) 6 stage moisture and aeration conditions scalar (from aridic or well aerated to permanently wet or reductic conditions), and (iii) 2-3 stage soil development scalar, which characterizes the intensity of soil forming processes (accumulation of humus, podzolization). The organic soils pedo-ecological schema, which links with histic postlithogenic soils, is elaborated for characterizing of peatlands superficial mantle (form 23.7% from whole soil cover). The position each peat soil species among others on this organic (peat) soil matrix schema is determined by mean of 3 scalars: (i) peat thickness, (ii) type of paludification or peat forming peculiarities, and (iii) stage of peat decomposition or peat type. On the matrix of abnormally developed (synlithogenic) soils (all together 3.9%) the soil species are positioned (i) by proceeding in actual time geological processes as erosion, fluvial processes (at vicinity of rivers, lakes or sea) or transforming by anthropogenic and technological processes, and (ii) by 7 stage moisture conditions (from aridic to subaqual) of soils. The most important functions of soil cover are: (i) being a suitable environment for plant productivity; (ii) forming adequate conditions for decomposition, transformation and conversion of falling litter (characterized by humus

Full Text Available Methis is a new quarterly journal of literary and cultural studies in Estonia, a collaborative publication of the Department of Literature and Theatre Research of the University of Tartu and the Estonian Literary Museum. Its predecessors were series of collections of articles “Studia litteraria estonica“ of the Chair of Estonian Literature of the University of Tartu, and series such as “Tradition and pluralism”, and “Accommodating Texts” of the Estonian Literary Museum. With due respect to its genealogy, the purpose of Methis is to provide a new forum for publication by young and established scholars, balancing between international and Estonian-language readerships. Since any new periodical is fraught with risk, especially in a country where the scholarly base is small, it is crucial to take the measure of the landscape, both in the homeland and in Europe. The pressures of publishing must take into account perils and perishing, both on the level of individual scholars and their institutions. Methis is primarily and philosophically committed to peer-reviewed publishing in the Estonian language. The editorial board sees this not as a symptom of insularity, but rather as a deep, intentional investment in the cultivation of scholarly Estonian as a flexible, rich medium for scientific expression and communication at a level in keeping with the highest international standards. The first double issue of Methis, published in December 2008 under the editorship of Dr. Marin Laak and Dr. Sirje Olesk, was devoted to the Young Estonia movement of the last decades of the 19th century and the opening decade of the 20th – a time of crucial self-positioning of Estonian scholars, thinkers and activists with respect to the Europe they both imagined and encountered in their peregrinations and political exile. It is, however highly and fortunately symbolic of Methis’ position in Estonian letters that this issue is published in English, and that it

2006-12-01

Full Text Available The article handles general developments and changes in book trade which took place in Estonia during the second half of the 19th century. The aim is to show the formation of bookshops trading with Estonian books and to analyse the activities of Estonian booksellers.The survey is based on the research literature and on the master thesis by Signe Jantson “Raamatukaubandus Eestis aastatel 1850–1917: raamatukauplused ja nende omanikud” (Book trade in Estonia 1850–1917: bookshops and their owners [9]. In this study great importance wasattached to the national and social origin of bookshop owners and their activities. Up to the middle of the 19th century the book production and dissemination in Estonia was in the hands of Baltic German entrepreneurs and depended on the political and economic developments not only in Russia but also in Germany. In the middle of the 19th century there were only 5 bookshops in Estonia located in bigger towns – Tallinn and Tartu. In 1870 the number of bookshops reached 13. The greater ascent can be noticed in the last decade of the period – 1870–1880 when 20 new bookshops were opened. In 1867 Heinrich Laakmann, a German origin publisher and the printing shop owner opened the first bookshop in Tartu to sell Estonian language books. The economic and political reforms as well as the national awakening movement favoured the engagement of Estonians in the sphere of book production and dissemination. Increasing publishing of Estonian language books enabled the development of trade. At the end of the national awakening period most of the bookshop owners were already of Estonian origin. Since 1870ies the number of Estonian bookshops started to grow and at the end of the 19th century they outnumbered German and Russian shops. In all over Europe book trade concentrated into the big cities (in the case of Estonia in Tallinn and Tartu, but bookshops were opened also in the rural area (small towns and villages

2012-05-01

Full Text Available The brachiopod Hirnantia sagittifera (M’Coy and trilobite morphs of the genus Mucronaspis from the topmost Ordovician Porkuni Stage of the central East Baltic are described and compared with those from the Hirnantian Stage of other regions. These important Hirnantian taxa occur in the Livonian Tongue of the Central Baltoscandian Facies Belt of the Baltic Basin, where the Porkuni Stage is represented by the non-graptolitic Kuldiga and Saldus formations. Hirnantia sagittifera appears in the lowermost part of the Porkuni Stage and is rather widely distributed in the basin in spite of its rare finds in each locality. Our study of trilobites of the genus Mucronaspis has enabled us to observe morphological changes in its exoskeleton in time and to identify a succession of five morphotypes (morphs. In some characteristics these morphs are similar to those of different alleged species of the genus Mucronaspis (M. olini, M. danai, M. ganabina, M. mucronata but they cannot be definitely assigned to any of these species due to some variances. However, here for the first time a stratigraphically ordered collection is presented, which deserves attention in revising the taxonomy of highly variable Mucronaspis. The described brachiopods and trilobites occur mainly in the strata correlated with the Normalograptus extraordinarius graptolite Biozone. However, the uppermost finds of both taxa come from strata correlated with the N. persculptus Biozone.

Estland im Sog der Russischen Volkswirtschaft? Estonia Being Caught Up in Russian Turmoil?

Full Text Available Against the backdrop of the Ukraine crisis and Russia’s economic problems, the authors pose the question to what extent the Estonian economy still relies on foreign trade with Russia and which costs Estonia might bear in the course of an aggravation of the lingering East-West conflict. Estonian trade relations with Russia as well as Estonia’s integration in the European and global division of labor are analyzed by a gravity model which also incorporates the trade foreign trade of the Baltic neighbors Latvia and Lithuania as benchmark countries. The authors find that even before the crisis Estonia’s trade with Russia lost weight and the dependency on Russian export and import markets diminished. By an in-depth analysis of Estonia’ sectoral trade patterns these findings were confirmed for the majority of industries. Only in the case of the Estonian milk industry the authors observe significant effects of Russian sanctions. In contrast to this particular case, Estonia becomes increasingly independent from imports of Russian natural gas which in the past made the country vulnerable to political blackmail. The authors conclude that regional and sectoral diversification of Estonian trade patterns induced by the current crisis will help the country to improve its international competitiveness and its economic integration into world markets.

Improved imputation accuracy of rare and low-frequency variants using population-specific high-coverage WGS-based imputation reference panel.

Genetic imputation is a cost-efficient way to improve the power and resolution of genome-wide association (GWA) studies. Current publicly accessible imputation reference panels accurately predict genotypes for common variants with minor allele frequency (MAF)≥5% and low-frequency variants (0.5≤MAF<5%) across diverse populations, but the imputation of rare variation (MAF<0.5%) is still rather limited. In the current study, we evaluate imputation accuracy achieved with reference panels from diverse populations with a population-specific high-coverage (30 ×) whole-genome sequencing (WGS) based reference panel, comprising of 2244 Estonian individuals (0.25% of adult Estonians). Although the Estonian-specific panel contains fewer haplotypes and variants, the imputation confidence and accuracy of imputed low-frequency and rare variants was significantly higher. The results indicate the utility of population-specific reference panels for human genetic studies.

Describing temporal variability of the mean Estonian precipitation series in climate time scale

Science.gov (United States)

Post, P.; Kärner, O.

2009-04-01

Applicability of the random walk type models to represent the temporal variability of various atmospheric temperature series has been successfully demonstrated recently (e.g. Kärner, 2002). Main problem in the temperature modeling is connected to the scale break in the generally self similar air temperature anomaly series (Kärner, 2005). The break separates short-range strong non-stationarity from nearly stationary longer range variability region. This is an indication of the fact that several geophysical time series show a short-range non-stationary behaviour and a stationary behaviour in longer range (Davis et al., 1996). In order to model series like that the choice of time step appears to be crucial. To characterize the long-range variability we can neglect the short-range non-stationary fluctuations, provided that we are able to model properly the long-range tendencies. The structure function (Monin and Yaglom, 1975) was used to determine an approximate segregation line between the short and the long scale in terms of modeling. The longer scale can be called climate one, because such models are applicable in scales over some decades. In order to get rid of the short-range fluctuations in daily series the variability can be examined using sufficiently long time step. In the present paper, we show that the same philosophy is useful to find a model to represent a climate-scale temporal variability of the Estonian daily mean precipitation amount series over 45 years (1961-2005). Temporal variability of the obtained daily time series is examined by means of an autoregressive and integrated moving average (ARIMA) family model of the type (0,1,1). This model is applicable for daily precipitation simulating if to select an appropriate time step that enables us to neglet the short-range non-stationary fluctuations. A considerably longer time step than one day (30 days) is used in the current paper to model the precipitation time series variability. Each ARIMA (0

The Estonian delegation had been invited by Helsinki Energy to participate in the Nordic-Baltic District Heating Symposium. Distance heating enjoys a wide popularity in the Nordic countries. For heating purposes the use of biofuels, incl. peat, is highly recommended. Biofuels have found wide use in the Nordic countries, the share of peat being more considerable in Finland. The Estonians attended also the MODIS Workshop and made a visit to heat enterprises. (author)

Full Text Available In Estonian art history, the beginning of the 20th century is the era of the birth of nationalist art. This is the time when the first artists to study abroad, the brothers Paul and Kristjan Raud, and Ants Laikmaa return home from their studies in Düsseldorf and Munich. In the homeland, these artists’ cultural and political spirit brought them into contact with the Young Estonians, one generation younger than they were, whose overall world-view and artistic views they came to shape. The program of the Young Estonians included the furthering of cultural life as a whole; therefore they participated enthusiastically in discussions about the visual arts, and ways in which to advance art in the homeland. Through the mediation of Ants Laikmaa, they made contact with Nikolai Triik, an artist of their own generation, who in turn engaged his former fellow students from the Stieglitz School of Applied Arts in St. Petersburg – Aleksander Tassa, Jaan Koort, and Konrad Mägi. The interests and travel destinations of writers and artists were similar: they found themselves drawn primarily to Scandinavia, then Paris. Young Estonia’s almanacs and magazines were illustrated and adorned by reproductions of these same artists’ works, and artists contributed their writings on art to the publication. Nikolai Triik was artistic editor for the Young Estonia magazine, thanks to his stronger ties with the homeland and his greater authority. In the years 1909 and 1914 Young Estonia organized art exhibits, in which several artists studying abroad found their first reception among a homeland public. Young Estonia created a new standard in Estonian book design. Discussions began around the question of ”nationalism” in art. The Young Estonia period 1905–1915 was an era of great change in Estonian art, and the artists connected with the movement played a major role in subsequent developments. Together they established the art association ”Pallas” in 1918

Artistic Alliances and Revolutionary Rivalries in the Baltic Art World, 1890-1914

Full Text Available In the areas now known as Estonia and Latvia, art remained a matter for the Baltic German minority throughout the nineteenth century. When ethnic Estonian and Latvian artists gained prominence in the late 1890s, their presence threatened Baltic German hegemony over the region’s culture. In 1905, revolution in the Russian Empire spilled into the Baltic Provinces, sparking widespread anti-German violence. The revolution also galvanized Latvian and Estonian artists towards greater cultural autonomy and independence from Baltic German artistic institutions. This paper argues that the situation for artists before and after the 1905 revolution was not simply divisive along ethnic lines, as some nationalist historians have suggested. Instead, this paper examines how Baltic German, Estonian and Latvian artists oscillated between common interests, inspiring rivalries, and politicized conflicts, questioning the legitimacy of art as a universalizing language in multicultural societies.

Should Estonia have a nuclear power station?(Part 1)

Frey, T.

1992-01-01

In developing countries the problem of energy supply can be of paramount importance. Estonia, however, being the small country of a small nation, has to take into account special considerations before deciding on the possible introduction of nuclear electricity. Should another disaster like that of Chernobyl take place on Estonian territory, the whole nation might perish. Therefore, those scientists who place national interests above all have been active looking for alternative sources of energy. The present paper discusses the situation in Northern Europe and draws the readers' attention to the still unsolved problem of nuclear waste disposal. The paper emphasises the fact that the Fifth Estonian Conference on Ecology regarded nuclear energy as entirely unacceptable for Estonia and declared its full support for the decision taken by the Estonian Government not to consider the application of nuclear power in Estonia before the year 2000.

Far-field thermomechanical response of argillaceous rock to emplacement of a nuclear-waste repository

Before heat-producing wastes can be emplaced safely in any argillaceous rock, it will be necessary to understand the far-field thermal and thermomechanical response of this rock to waste emplacement. This report presents the results of a first series of calculations aimed at estimating the far-field response of argillite to waste emplacement. Because the thermal and mechanical properties of argillite are affected by its content of expandable clay, its behavior is briefly compared and contrasted with that of a shale having the same matrix thermal properties, but containing no expandable clay. Under this assumption, modeled temperatures are the same for the two rock types at equivalent power densities and reflect the large dependence of in-situ temperatures on both initial power density and waste type. Thermomechanical calculations indicate that inclusion of contraction behavior of expandable clays in the assumed argillite thermal expansion behavior results, in some cases, in generation of a large zone in and near the repository that has undergone volumetric contraction but is surrounded by uniformly compressive stresses. Information available to date indicates that this contraction would likely result in locally increased fluid permeability and decreased in-situ thermal conductivity, but might well be advantageous as regards radionuclide retention, because of the increased surface area within the contracted zone. Assumption of continuous and positive expansion behavior for the shale eliminates the near-repository contraction and tensional zones, but results in near-surface tensional zones directly above the repository

Clay/shale has been considered as potential host rock for geological disposal of high-level radioactive waste throughout the world, because of its low permeability, low diffusion coefficient, high retention capacity for radionuclides, and capability to self-seal fractures. For example, Callovo-Oxfordian argillites at the Bure site, France (Fouche et al., 2004), Toarcian argillites at the Tournemire site, France (Patriarche et al., 2004), Opalinus Clay at the Mont Terri site, Switzerland (Meier et al., 2000), and Boom clay at the Mol site, Belgium (Barnichon and Volckaert, 2003) have all been under intensive scientific investigation (at both field and laboratory scales) for understanding a variety of rock properties and their relationships to flow and transport processes associated with geological disposal of radioactive waste.

From 1994 to 1996, the preliminary investigation carried out by Andra, identified a sector favourable for hosting a laboratory in argillaceous Callovo-Oxfordian formation which has a thickness of 130 m and lies more than 400 m below ground level. In November 1999 Andra began building an Underground Research Laboratory (URL) with a 3D seismic survey over 4 km 2 . From 2000 to 2004, large programs of boreholes were carried out on site and on the sector in order to define the characteristics of formations, to improve the regional geological and hydrogeological knowledge and to provide an accurate definition of structural features in Callovo-Oxfordian argillites and Dogger limestones. These drilling programs have provided a fine characterization of the argillites on the laboratory area and a good correlation of geological properties at a sector scale. (author)

Estonian mineral resources are deposited in low depth and mining fields are large, therefore vast areas are affected by mining. There are at least 800 deposits with total area of 6,000 km 2 and about the same number of underground mines, surface mines, peat fields, quarries, and sand and gravel pits. The deposits cover more than 10% of Estonian mainland. The total area of operating mine claims exceeds 150 km 2 that makes 0.3 % of Estonian area. The book is written mainly for the people who are living or acting in the area influenced by mining. The observations and research could benefit those who are interested in geography and environment, who follow formation and look of mined-out landscapes. The book contains also warnings for careless people on and under the surface of the mined-out land. Part of the book contains results of the research made in 1968-1993 by the first two authors working at the Estonian branch of A.Skochinsky Institute of Mining. Since 1990, Arvi Toomik continued this study at the Northeastern section of the Institute of Ecology of Tallinn Pedagogical University. Enno Reinsalu studied aftereffects of mining at the Mining Department of Tallinn Technical University from 1998 to 2000. Geographical Information System for Mining was studied by Ingo Valgma within his doctoral dissertation, and this book is one of the applications of his study

Full Text Available Abstract Background The Eosinophil Cationic Protein (ECP is a potent multifunctional protein. Three common polymorphisms are present in the ECP gene, which determine the function and production of the protein. The aim was to study the relationship of these ECP gene polymorphisms to signs and symptoms of allergy and asthma in a community based cohort (The European Community Respiratory Health Survey (ECRHS. Methods Swedish and Estonian subjects (n = 757 were selected from the larger cohort of the ECRHS II study cohort. The prevalence of the gene polymorphisms ECP434(G>C (rs2073342, ECP562(G>C (rs2233860 and ECP c.-38(A>C (rs2233859 were analysed by DNA sequencing and/or real-time PCR and related to questionnaire-based information of allergy, asthma, smoking habits and to lung functions. Results Genotype prevalence showed both ethnic and gender differences. Close associations were found between the ECP434(G>C and ECP562(G>C genotypes and smoking habits, lung function and expression of allergic symptoms. Non-allergic asthma was associated with an increased prevalence of the ECP434GG genotype. The ECP c.-38(A>C genotypes were independently associated to the subject being atopic. Conclusion Our results show associations of symptoms of allergy and asthma to ECP-genotypes, but also to smoking habits. ECP may be involved in impairment of lung functions in disease. Gender, ethnicity and smoking habits are major confounders in the evaluations of genetic associations to allergy and asthma.

In the introductory part of her paper, under the subtitles Shortly about the condition of peatlands in Europe of today and The future of Estonian peatlands, Elvi Lode, a wetland hydrologist of the Institute of Ecology at Tallinn University of Educational Sciences, considers the condition of peatlands in Europe and the future of Estonian peatlands. The annual peat production quota established by the Government of Estonia (2.78 million t) is compared with reserves established in the course of the latest inventory of Estonian peat cuttings and the existing natural and managed peatlands. In view of the allowed usable peat reserves in Estonia the area for peat cuttings in the future may be about 20 % larger than the present area under natural bog centre sites. Based on world experience and knowledge in the parts subtitled Restoration - a question of ethics and Restoration of mires a question of aesthetics the tasks related to the restoration of peatlands have been stated and institutions in charge have been determined.

Full Text Available The article expounds on some trends witnessed in the use of object cases in Estonian. It is a synchronous research basing on Estonian learner language and standard language corpus-driven and corpus-based comparative language usage analysis. The corpus-driven analysis provides evidence to phenomena, endemic to a given language usage variant, followed up by corpus-based analysis. The point of reference is the concept, according to which the learner language use reflects the processes inherent to development of the standard language, manifested among others also by changes of object cases and alternating grammatical cases. Those processes would not reveal themselves, if the language system should lack the respective readiness. The comparative corpus-driven analysis of different language usage variants highlights the phenomena deriving from language transfer on the one hand, and from the Finno-Ugric substance of Estonian on the other hand, which the contrastive and error analysis incidental to word or category fails to bring to the fore.

The Huanghuachang section near Yichang, southern China meets the requirements of Global Stratotype Section and Point (GSSP) for the base of the Middle Ordovician Series and the yet-to-be-named third stage of the Ordovician System (or lower stage of Middle Ordovician Series). The conodont succession at the section is complete across the Lower to Middle Ordovician series boundary and several excellent phylogenetic lineages of Baltoniodus, Trapezognathus, Periodon, and Microzarkodina are represented. The definition of the base of the Middle Ordovician is proposed to be the first appearance datum (FAD) of Baltoniodus? triangularis in the section. It is followed closely by the FAD of Microzarkodina flabellum, which is taken as a reasonable proxy for the boundary. This level approximates the boundary between the lower and upper intervals of the Azygograptus suecicus graptolite Biozone, and nearly coincides with the base of the Belonechitina henryi chitinozoan Biozone.The proposed GSSP for the base of the international Middle Ordovician Series is located in a roadside exposure at the base of Bed (SHod) 16, 10.57 m above the base of the Dawan Formation in the measured Huanghuachang section near Yichang City, southern China. The same faunal succession is also recorded from the Chenjiahe (formerly Daping) section, 5 km to the north of the Huanghuachang section. The proposed boundary horizon can be recognized and correlated globally with high precision in both relatively shallow-water carbonate facies as well as in deep-water graptolite facies.

A total of 18 children (9 boys and 9 girls between the ages of 4 and 8 took part in trial tests: 15 Estonian mother-tongue and 3 Estonian-Russian bilingual mother-tongue children. The article was an analysis of the suitability of the test and an analysis of the test’s preliminary results in assessing Estonian children’s narrative skills. The preliminary test showed that storytelling is difficult for children. It emerged that when producing a narrative, it was not natural for children to indicate a starting point (giving time or place, but rather storytelling began immediately with a conflict and goal as internal components. Challenges and goals also turned out to be the most common and therefore the simplest content in the children’s narratives. There was little complexity in the children’s narratives, and most presented individual goals without conflicts or outcomes. Least common was all three macrostructural components (goal-conflict-outcome in succession in the children’s stories. Stories that achieved higher scores in production were also more complex and these displayed components and sequencing of components that show the cohesion and completeness of the work. Stories that achieved lower scores rather contain individual goals of narrative production, but with conflicts and outcomes to a lesser extent. In the Estonian children’s narratives, there were few words referring to a person’s inner feelings or reactions. The results showed that Estonian children find it difficult to use emotion words, which is evidenced by their limited use of IST words (including emotion words as well as their null-rated understanding of the internal reactions and states of individuals.

A number of special aspects, trends and problems in trade and investment ties are detected. The aim of the study is to uncover key motivation behind the actions of both Russia and Estonia, to identify the drivers for economic and political development in the region, and to work out recommendations to adjust them. The questions put forward by the authors of this article could not be more topical at the time, when Russian economic situation is obviously getting worse and capital flight (to the neighboring EU Member States is likely to increase. The method of the study is comparative analysis of the impact on economic ties made by Russian-Estonian crisis of 2007 and the current international tension around Ukraine. The regional fossil fuel market and the possibilities of Gazprom involvement in its development are also analyzed. It is concluded that political motives are still important for Estonian decisionmaking, though they are balanced out by measures of business support (despite some of these measures being taken by the EU bodies. The role of political factor for the Russian side is increasing. It is acknowledged that there is a growing number of missed economic opportunities in the Russian Northwest.

The determination of the thermal properties of clayey rocks is fundamental for predicting the behaviour a radioactive waste geological repository, and geothermal and oil reservoirs. The main objectives of this thesis work were to 1) better understand the effects of the parameters controlling the thermal conductivity, 2) study to which extent the laboratory measurements can be extrapolated to the field, and 3) find relationships between the thermal conductivity and other quantities easier to measure on the field, e.g. the P- and S- wave velocities. The study was conducted on 24 cores of marls carbonates and argillites coming from the EST205 borehole of the M/HM site (ANDRA). After a complete characterisation of the samples, their thermal conductivities were measured using a stationary method. The borehole was drilled with a special oil-based mud to avoid damaging the argillites, and many logs were available. Hence, it is ideal to study the properties of clayey rocks and compare them with field data. The results show the major effect of the microstructure (mainly the particles orientation), which causes the important anisotropy of the thermal conductivity in the marls and argillites. For all lithologies, linear relationships between the conductivity and the P- and S- wave velocities were obtained. The application of this experimental law to the sonic log helped building a synthetic log of thermal conductivity. Finally, we developed a heat probe, which allows measurements in function of temperature and saturation. We showed with this method that the thermal conductivity increases quasi-linearly with the saturation in a sandstone and a carbonate samples. (author)

From 1982 to 2014, physicians’ attitudes towards the health risks of smoking improved in Estonia. However, their assessment of a causal role of smoking in smoking-related diseases was related to their own smoking habits and ethnicity. A further decline in smoking among Estonian physicians would require special efforts targeted at physicians. Societal pressure from a national policy could support a further decline in the social acceptability of smoking in Estonia and developments in medical education could provide continuing evidence-based information about the health effects of smoking to Estonian physicians.

Full Text Available Performance evaluation is not a new concept in private sector, while in public sector organisations it has been taken into use since the implementation of performance management. Evaluation is necessary to make the future-oriented management decisions based on the information available today, in order to achieve desired performance. The authors analysed self-evaluation reports prepared in Estonian general schools in 2008. Self-evaluation reports were analysed to see, if the relationships and roles, patterns of governance and accountability, flow of resources, the headmaster’s role, educational and other values in Estonian schools have hanged enough, to provide education service, which responds to the high expectations of contemporary society. Although the analyses of OECD surveys’ results show that the organising of the Estonian educational sector is a good example for many other countries, the actual situation in the schools is not as positive. There are high expectations put on schools by the policymakers’ level, but schools do not have enough ability to reach them. There is a lack of financial resources, knowledge and organisational willingness

Hazardous substances in the aquatic environment of Estonia.

The Water Framework Directive (WFD) aims to regulate the management of European surface water bodies. Directive 2008/105/EC, which establishes the environmental quality standards of priority substances and certain other pollutants, the content of which in the surface water should be monitored, has been transposed by the Estonian Ministry of Environment 9 September 2010 Regulation No. 49. Sampled hazardous substances were selected primarily based on their toxicity, as well as their lifetime in environment and ability to accumulate in living organisms (bioaccumulation). The contents of hazardous substances and their groups determined from Estonian surface waters remained below the limits of quantifications of used analysis methods in most cases. However, the content of some heavy metals, mono- and dibasic phenols in the surface water/waste water and sewage sludge/bottom sediments can still reach the delicate levels in the Estonian oil shale region in particular. Among new substances analysed in Estonia historically first time in 2010, amounts of organotin compounds in sediments and some alkylphenols, their ethoxylates and phthalates were found in various sample matrices.

Full Text Available The aim of the article is to analyze the attitudes of 9th grade students at Russian- medium general education schools in Estonia toward the importance of competence in the official language. Semi-structured group interviews allow the voice of the language learner – in this case 15–16-year-old Russian school students – to be heard in the discussion of official language instruction. The analysis of these interviews reveals that Russian students’ attitudes toward the official language are shaped by their perception of Estonian as a small language, limited opportunities to use the language in their immediate environment, and the role of different languages on the job market, but also by the students’ national and linguistic identity. One primary conclusion is that in these students’ eyes, the Estonian language has only instrumental value, that is, it is seen merely as a tool needed for self-actualization. Russian youths do not see the Estonian language as part of their identity, and question its sustainability (and therefore the benefit of studying it in comparison to larger world languages.

Hydrogen transfer experiments and modelization in clay rocks for radioactive waste deep geological repository

International Nuclear Information System (INIS)

Boulin, P.

2008-10-01

Gases will be generated by corrosion of high radioactive waste containers in deep geological repositories. A gas phase will be generated. Gas pressure will build up and penetrated the geological formation. If gases do not penetrate the geological barrier efficiently, the pressure build up may create a risk of fracturing and of creation of preferential pathways for radionuclide migration. The present work focuses on Callovo-Oxfordian argillites characterisation. An experiment, designed to measure very low permeabilities, was used with hydrogen/helium and analysed using the Dusty Gas Model. Argillites close to saturation have an accessible porosity to gas transfer that is lower than 0,1% to 1% of the porosity. Analysis of the Knudsen effect suggests that this accessible network should be made of 50 nm to 200 nm diameter pores. The permeabilities values were integrated to an ANDRA operating model. The model showed that the maximum pressure expected near the repository would be 83 bar. (author)

Document available in extended abstract form only. Long term deep underground storage of radioactive nuclear waste is planned in the East of France within an argillaceous rock layer (the host rock), also called argillite, situated at ca. 450-500 m depth. Andra, the French national agency for nuclear waste management, is in charge of assessing the feasibility, the safety and the performance of this underground disposal. The drilling of storage tunnels generates an Excavated Damaged Zone (EDZ), where argillite is macro-cracked in various locations. This requires strengthening by different means, e.g. shotcrete or pre-fabricated concrete arches. It is also expected that underground water seepage will contribute to argillite sealing: mainly self-sealing, and sealing at the interface with concrete. Sealing phenomena include crystalline swelling of smectitic clay components of argillite and inter-particle swelling of clay minerals due to osmosis mechanisms. Small scale pores and mineral organisation of the COx clay-stone are widely acknowledged to control transfer properties of water, gas and varied solutes. In order to assess these properties, the COx small-scale structure has been imaged down to micrometric resolution by various means, including classical Scanning Electron Microscopy (SEM), X-ray computed microtomography and autoradiography. To go further into pore and mineral characterisation of COx clay-stone, the following investigations are currently under way: (i) acquiring/quantifying the 3D geometry of the pore network of undisturbed COx with a nano-metric resolution and (ii) imaging/quantifying the small-scale (mm-nm) structure of self-sealed volumes. The FIB (Focused Ion Beam) /SEM technique allows performing 3D observations of solid volumes of ca. a few microns, with a resolution of about ten nanometers, by acquiring and computing regularly spaced 2D SEM images. This technique provides quantification of the 3D spatial distribution mainly of macro- and meso

The EBRD Energy Sector Emergency Loan to Estonia has resulted in numerous benefits for the Estonian Energy Sector and the Estonian Society and the locals as well as the end users have developed themselves tremendously during the project. The substantial economic, environmental and energy saving effects of the loan project have been: Energy savings and improved energy efficiency in the electricity grid, the district heating networks, the district heating consumer installations, the energy production plants in terms of rehabilitated or converted boilers and burners, industrial consumer installations. The energy efficiency improvements have resulted in energy savings between 5% and 30%; Conversion of boilers from expensive imported heavy fuel oil to indigenous fuels such as peat and wood. The results are higher supply security, improved boiler efficiency, reduced emissions and reduced operation and maintenance costs; Rehabilitated district heating networks resulted in reduced heat and water losses, improved operation of installations and reduced maintenance costs; Rehabilitated electricity grids with fewer break-downs, reduced maintenance costs and improved energy efficiency as results; Improved operation of the larger energy utilities resulting in lower operational costs, improved dispatch of the energy systems and speedier actions in case of break-downs. The economic indicators, pay-back time and Internal Rate of Return show that a large number of the projects have had a substantial impact on the Estonian economy and that the projects have been sound investments. The recommendations for the local completion of the work in Estonia are: The Juri boiler plant should be carefully attended to by the PMU and the Estonian authorities. (Abstract Truncated)

Sedimentology of middle ordovician carbonates in the Argentine precordillera: evidence of regional relative sea-level changes

Science.gov (United States)

Keller, M.; Eberlein, S.; Lehnert, O.

1993-07-01

The Las Aguaditas Formation in the Argentine Precordillera of San Juan is the only Ordovician carbonate sequence deposited on a slope. Spiculites, mudstones and calcisiltites represent the autochthonous sediments, characterized by a fine lamination, rare fossils and their dark colour. The pelagic fauna consists of rare radiolarians/calcispheres, trinucleid trilobites, graptolites and conodonts. The latter are typical of an open marine environment and proved a Llanvirn—Llandeilo age for the Las Aguaditas Formation. In the upper part of the succession there are several intercalations of megabreccias. Their thickness decreases from about 20 to 4 m towards the top of the formation, accompanied by an increasing amount of carbonate turbidites. The clasts of the breccias are derived from the slope as well as the platform. Each of the megabreccia horizons represents a system of channels, lobes and interchannel deposits, which together form a slope apron. On top of the lower breccia a small biostrome developed, where bryozoans and crinoids are preserved in an autochthonous position. Sedimentation of the Las Aguaditas Formation started with the drowning of the underlying carbonate platform (San Juan limestones). Near the Arenig-Llanvirn boundary, a rapid ecstatic sea-level rise led to the deposition of graptolitic black shales and mudstones. Upwards, allochthonous carbonates become increasingly abundant. The onset of megabreccia deposition coincides with a major relative sea-level fall, caused by block movements in connection with rifting. The subsequent transition from breccia formation towards turbiditic sedimentation corresponds to an environmental shift from the slope towards the toe of slope and basin and marks a renewed moderate sea-level rise.

Kinetics and reversibility of radionuclide sorption reactions with rocks. Progress report for fiscal year 1979

Sorption-desorption reactions of cesium, strontium, neptunium, americium, and plutonium on basalt, granite, and argillite were observed for 218 days. Equilibrium in batch experiments was not reached for most radionuclides even after this long time. Reactions of the crushed rock with ground waters (dissolution, hydrolysis, precipitation, etc.) also did not reach equilibrium after 150 days. The dissolution of basalt is accompanied by the formation of colloidal particles which contain Si, Fe, Ca, and Al. These colloids sorb Cs, Sr, Am, and Pu during equilibration. Some of the colloids pass through 0.3-μm flters, are not retained even on 0.01-μm filters and, therefore, cause calculated K/sub d/ values to be too low. Samples of crushed basalt, granite, and argillite were artificially weathered by continuous leaching with distilled water for 6 months both in air and in an oxygen-free stream of nitrogen gas. The weathered rock was then characterized for surface area, surface structure, cation exchange capacity, and composition of weathered surface on the rock. Comparisons were made of radionuclide sorption (after 14 days) on fresh rock, rock weathered in air, and rock weathered in N 2 . Sorption on rocks weathered in N 2 generally is less than on rock weathered in air. This is possibly due to the lack of an Fe(OH) 3 coating on the rock weathered in N 2 . The Fe(OH) 3 is known to scavenge cations and silica from solution. Sorption of Cs, Si, Am, and Pu is strongly affected by weathering basalt and argillite. However, the cation exchange capacity is changed very little, suggesting that ion exchange plays a minor role in sorption of these radionuclides

Foreland basin receives large amounts of synorogenic infill that is eroded from the adjacent exhumed mountain belt, and therefore provides the important information on exhumation evolution. Furthermore, a complete stratigraphic sequence of Taiwan mountain belt consists of five units of Miocene sedimentary rocks (the Western Foothills and the uppermost sequence on the proto-Taiwan mountain belt), Oligocene argillite (the Hsuehshan Range), Eocene quartzite (the Hsuehshan Range), Eocene-Miocene slate and schist (Backbone Range), and Cretaceous schist (Backbone Range) from top to bottom. Based on the progressive unroofing history, the initiation of foreland basin received sedimentary lithic sediments from the uppermost sequence of proto-Taiwan mountain belt, afterwards, and receiving low- to medium-grade metamorphic lithic sediments in ascending order of argillite, quartzite, slate, and schist clasts. Therefore, the sedimentary lithics from mountain belt were deposited which represents the onset of the mountain uplift. In this study, the first appearance of sedimentary lithic sediments occurs in the Hengchun Peninsula at the middle Miocene (ca. 12-10 Ma). Thus, sandstone petrography of the late Miocene formation (10-5.3 Ma) shows a predominantly recycled sedimentary and low-grade metamorphic sources, including sandstone, argillite and quartzite lithic sediments of 10-25% which records erosion to slightly deeper metamorphic terrane on the mountain belt. Based on the results of previous thermogeochronological studies of the Yuli belt, it suggests that the middle Miocene occurred mountain uplift. The occurrence of low-grade metamorphic lithic sediments in the Hengchun Peninsula during late Miocene is coincident with the cooling ages of uplift and denuded Yuli schist belt at the eastern limb of Backbone Range.

The propagation of an alkaline wave through a clay rock has been investigated- The wave is generated by a cementitious matrix through the Callovo-Oxfordian argillite of the Meuse Haute-Marne Laboratory (-480 m depth). The argillite itself is composed of quartz, micas, calcite and an interstratified l/S. In order to characterise the interactions between the alkaline fluid and the argillaceous medium, dynamic column experiments have been carried out. The originality of the investigation methodology consists in exploiting the data generated from the breakthrough curves as well as from the characterisation of the solids extracted from the columns. Two types of processes having totally different reaction times have hence been thoroughly studied: - Fast surface adsorption and condensation reactions: On the one hand cation adsorption reactions by site ionisation have been characterised. They are responsible of the buffering effect of the clays. On the other hand an original reaction of calcium compound condensation in the interlayer space of the swelling clays has been revealed. These processes have been modelled and their simulations with the IMPACT calculation code showed that the models elaborated were very satisfying. - Strongly kinetically limited dissolution/precipitation reactions: The main primary phases dissolved are quartz and interstratified l/S. The precipitation of secondary phases are mainly C(A)SH and zeolites. After the injection of an alkaline fluid for 6 months at 60 deg C, the argillite is strongly amorphized but only 20 to 30% of the quartz and the interstratified I/S are dissolved. Therefore, dissolution kinetics of the primary phases and the solubility products of the main secondary phases have been determined. (author)

The underground radioactive waste disposal far exceeds the period of exploitation of common civil engineering works. These specific projects require to predict the irreversible deformations over a large time scale (several centuries) in order to assess the extension and to forecast the evolution of the EDZ (Excavation Damage Zone) around the cavity. In this study, the viscosity of three sedimentary argillaceous rocks has been studied under different conditions of uniaxial compression: static or cyclic creep tests, monotonic and quasistatic tests, performed across various strata orientations. Argillaceous rocks are studied as a possible host layer for radioactive waste disposals. Indeed, they present some of the physical characteristics and mechanical properties, which are essential for being a natural barrier: low permeability, high creep potential and important holding capacity of radioactive elements. The purpose of the experimental study was to shed some light over the mechanisms governing the development of delayed deformations and damage of argillaceous rocks. It relates three rocks: an argillite from East of France, a Tournemire argillite and a marl from Jurassic Mountains. On atomic scale, viscoplastic deformations are due to irreversible displacements of crystalline defects, called dislocations. The experimental study was also supplemented with observations on thin sections extracted from the argillite and marl samples using a SEM. The aim was to identify the mechanisms responsible for the time-dependent behaviour on a microstructural scale. Analytical simulations of the mechanical behaviour of the three rocks gave parameters used in different viscoplastic models. The best modeling was obtained with the viscoplastic model which takes account of the development of volumetric strains and of the damage anisotropy. (author)

Full Text Available After the restoration of independence in 1991, Estonia continued with a parallel school system with separate public schools operating for Russian- and Estonian-speaking children. Seen as a developmental ‘growing pains’ of a transitional state, during the last 27 years the separate school system has contributed to infrastructural difficulties, educational injustice, and societal segregation. This article investigates the role of private schools in addressing this injustice from the analytical angle of new institutionalism, structuration and intergroup contact theories. How do these institutions challenge and aim at changing the state language regime or path dependency in the language of education? Two case studies are presented in this article: The Open School, established in 2017 for children with different home language backgrounds and targeting trilingual competences; The Sakala Private School, established in 2009, offering trilingual education with Russian as a medium of instruction. During this period of nation-state rebuilding and globalization, we investigate whether developing a multilingual habitus is a way to address the issue of social cohesion in the Estonian society in. So far, no other studies of private initiatives in Estonian language acquisition planning have been done.

The use of teetaimed in Estonia, 1880s-1990s.

This research contributes to a better understanding of the criteria used for the selection of plants for making beverages. Worldwide, not only the leaves of Camellia sinensis, but also various other plants are used for making tea. We argue that the selection of plants for making tea (in Estonian teetaimed) depends on specific features possessed by or attributed to the plants. 54 plant taxa and one lichen were identified as being used for making tea, based on the analysis of Estonian historical handwritten archival records on plant use for the period from 1887 to 1994. The influence of popular literature on the use of plants for making tea was also assessed. The suitability of a plant for making tea depends on a combination of factors like multifunctional use, mild taste and attributed medicinal properties. The variety of medicinal properties attributed to teetaimed in folk medicine allowed herbal tea drinking to be considered as mild disease prevention. Hence, the roots of the Estonian tea tradition lie in the medicinal use of the plants, not oriental ceremonial tea drinking. Copyright © 2012 Elsevier Ltd. All rights reserved.

Oil shale mines and their realizable production

Habicht, K.

1994-01-01

The production of Estonian oil shale depends on its marketing opportunities. The realizable production is a function of the oil shale price, which in turn depends on production costs. The latter are dependent on which mines are producing oil shale and on the volume of production. The purpose of the present article is to analyze which mines should operate under various realizable production scenarios and what should be their annual output so that the total cost of oil shale production (including maintenance at idle mines) is minimized. This paper is also targeted at observing the change in the average production cost per ton of oil shale depending on the realizable output. The calculations are based on data for the first four months of 1993, as collected by N. Barabaner (Estonian Academy of Sciences, Institute of Economy). The data include the total production volume and production cost from the mines of RE 'Eesti Polevkivi' (State Enterprise 'Estonian Oil Shale'). They also project expenses from mine closings in case of conservation. The latter costs were allocated among mines in direct proportion to their respective number of employees. (author)

Full Text Available The problems related to industry are topical because there is no real industrial policy in Estonia today. The aim of this article is to provide an overview of the stages of development of Estonian industry in different periods (…–1858, ……, 2010–…. Estonian industry has been predominantly concentrated to Tallinn and its immediate vicinity and to other cities and towns of North Estonia, to a lesser extent also to other larger Estonian cities and county centres and their immediate vicinity. Disposition of industry in Estonia has been predominantly related to appropriate geographical conditions and existence of local natural resources and raw materials, traditions and experience but has also depended on decisions on economic policy in different periods, both on the national and local government levels. After regaining of independence there have been no particular fundamental positive changes in regional industrial development in Estonia, we can rather even talk about regression instead for some places. These are, however, necessary in order to ensure jobs to people in all inhabited regions, above all in rural areas. It would also contribute to a balanced regional development in Estonia.

There was a meeting of the Estonian Power and Heat Association in Paernu summarizing the Association's activities in 1998. Only local fuels such as peat and wood chips (70 %) and oil shale (30 %) are used for district heating in Paernu. There is an interest in the combined production of heat and power. The Association plans to set up the respective committee on engineering. The Energy Market Inspectorate was formed in Estonia on January 22, 1998. On April 1, 1999, the Estonian Center for Engineering Inspectorate was opened. The newly formed body will be dealing with accidents likely to happen. The banks are interested in financing Estonian energy projects as power engineering is a field of vital importance with stable money flows and low risk. One can get capital from Estonia more easily and quickly, so far to a limited amount and at a higher interest (small projects at 15 to 20 per cent) than from outside (in case of 2 thousand million EEK at 5 %). The weighted average of heat sold in Estonia, without turnover tax, was 302 EEK/MWh), variance 150 to 490 EEK/MWh. (author)

A growing number of middle-income countries are scaling up youth-friendly sexual and reproductive health pilot projects to national level programmes. Yet, there are few case studies on successful national level scale-up of such programmes. Estonia is an excellent example of scale-up of a small grassroots adolescent sexual and reproductive health initiative to a national programme, which most likely contributed to improved adolescent sexual and reproductive health outcomes. This study; (1) documents the scale-up process of the Estonian youth clinic network 1991-2013, and (2) analyses factors that contributed to the successful scale-up. This research provides policy makers and programme managers with new insights to success factors of the scale-up, that can be used to support planning, implementation and scale-up of adolescent sexual and reproductive health programmes in other countries. Information on the scale-up process and success factors were collected by conducting a literature review and interviewing key stakeholders. The findings were analysed using the WHO-ExpandNet framework, which provides a step-by-step process approach for design, implementation and assessment of the results of scaling-up health innovations. The scale-up was divided into two main phases: (1) planning the scale-up strategy 1991-1995 and (2) managing the scaling-up 1996-2013. The planning phase analysed innovation, user organizations (youth clinics), environment and resource team (a national NGO and international assistance). The managing phase examines strategic choices, advocacy, organization, resource mobilization, monitoring and evaluation, strategic planning and management of the scale-up. The main factors that contributed to the successful scale-up in Estonia were: (1) favourable social and political climate, (2) clear demonstrated need for the adolescent services, (3) a national professional organization that advocated, coordinated and represented the youth clinics, (4) enthusiasm

Thermo-hydro mechanical modeling in unsaturated hard clay: application to nuclear waste storage

International Nuclear Information System (INIS)

Jia, Y.

2006-07-01

This work presents an elastoplastic damage model for argillite in unsaturated conditions. A short resume of experimental investigations is presented in the first part. The results obtained show an important plastic deformation coupled with damage induced by initiation and growth of microcracks. Influences of water content on the mechanical behaviour are also investigated. Based on experimental data and micro-mechanical considerations, a general constitutive model is proposed for the poro-mechanical behavior of argillite in unsaturated conditions. The time dependent creep has also been incorporated in they model. The performance of the model is examined by comparing numerical simulation with experimental data in various load paths under saturated and unsaturated conditions. Finally, the model is applied to hydro-mechanical coupling study of the REP experiment and thermo-hydro-mechanical coupling study of the HE-D experiment. A good agreement is obtained between experimental data and numerical predictions. It has been shown that the proposed model describe correctly the main features of the mechanical behaviour of unsaturated rocks. (author)

Strategic purchasing reform in Estonia: Reducing inequalities in access while improving care concentration and quality.

Science.gov (United States)

Habicht, Triin; Habicht, Jarno; van Ginneken, Ewout

2015-08-01

As of 2014, the Estonian Health Insurance Fund has adopted new purchasing procedures and criteria, which it now has started to implement in specialist care. Main changes include (1) redefined access criteria based on population need rather than historical supply, which aim to achieve more equal access of providers and specialties; (2) stricter definition and use of optimal workload criteria to increase the concentration of specialist care (3) better consideration of patient movement; and (4) an increased emphasis on quality to foster quality improvement. The new criteria were first used in the contract cycle that started in 2014 and resulted in fewer contracted providers for a similar volume of care compared to the previous contract cycle. This implies that provision of specialized care has become concentrated at fewer providers. It is too early to draw firm conclusions on the impact on care quality or on actors, but the process has sparked debate on the role of selective contracting and the role of public and private providers in Estonian health care. Lastly, the Estonian experience may hold important lessons for other countries looking to overcome inequalities in access while concentrating care and improving care quality.

The necessity of an administrative-territorial reform in a country: the case of Estonia. Administratiiv-territoriaalse reformi vajadus riigis: Eesti juhtum

Janno Reiljan

2012-01-01

Full Text Available The goal of this paper is to analyze the theoretical, political and organizational bases of the territorial division of the country into municipalities as well as empirical data of Estonian municipalities and offer a research direction for identifying conceptual solutions to the development problems in Estonian municipalities. The analysis of the theoretical approaches to municipal size pointed out that they are fragmented and incompatible. Some authors support small municipalities, and others large. The theoretical reasoning of both those directions is often strongly simplified and biased and a unified metatheoretical approach has not been established. The empirical analysis revealed that there is no empirical evidence to confirm either the presence of significant size related advantages among municipalities or the existence of an optimal municipal size considering current municipal functions and financing. The lack of theoretical and empirical evidence on the necessity for administrativeterritorial reform means that merging municipalities alone cannot significantly improve the public service delivery capacities and economic and democratic development of Estonian municipalities and that future studies should focus on analyzing public services from the perspective of their economic efficiency, quality and accessibility, and in doing so, determine the optimal size of regions for providing the various public services.

25 Years of Change in Management Control Systems and Business Education in Estonia

Directory of Open Access Journals (Sweden)

Ülle Pärl

2017-06-01

Full Text Available During the last 25 years, the Estonian economy has transitioned from a centrally planned economy to a market-oriented, globally open, highly competitive economy. Although during these years there has been fast growth and Estonians could tell a lot of success stories, research shows that management practices are still less advanced compared to those in enterprises from developed countries. Increased competition, openness and innovation increased the significance of more sophisticated management control systems (MCS. Researchers accentuate the role of managers and their education and training in using and developing more sophisticated MCS in companies. The objective of the current paper is to better understand how changes in the business environment, managerial training and education are connected to developments in MCS in Estonia. This article provides an overview of the statistics and studies completed in Estonia over the last 25 years. As this study shows, the last decade has brought a different level of internationalization and development in the business environment and business education. The problems associated with developments in MCS , using cloud technology, business education and managerial training are the same in Estonia as in developed countries. To develop the business and economic environment in the country, Estonian entrepreneurs need high-level data processing, analytical and financial education, and practical training courses.

Public Enterprises in Estonia as Instruments of Foreign Trade. Estnische öffentliche Unternehmen als Instrumente der Außenwirtschaftspolitik

Directory of Open Access Journals (Sweden)

Peter Friedrich

2016-10-01

Full Text Available The authors discuss whether a small country with shrinking population should apply public enterprises to improve its economic situation for purposes of external economic relations policy. The study refers to Estonia as an example. Estonia has developed public enterprises of the central state and of the municipalities since the reestablishment of the Estonian Republic. As public enterprise use private forms of law, some management problems occur because public firms are legally obliged to practice the management by objectives. The operationalization of welfare maximisation or achievement of sustainability of society to formulate goals for public enterprises was yet not successful. However, public firms should increase income, avoid monopoly positions of private firms, provide special public services, and should realize public goals. The activities of Estonian public enterprises and their goals show that Estonian enterprises can be used as instruments for foreign trade. The authors formulate a simple two-country model comprising a small and a big country. They introduce a public interest function referring to production, demand and employment, which allows the authors to argue that under conditions of shrinking population, the small country’s public interests, becomes reduced. They show that employing public enterprises diminishes negative effects on public interests. Even some types of inefficient public firms may lead to improvements.

Full Text Available Finnish raters’ beliefs about assessing Estonian speakers in a Finnish language test: easy or difficult? This paper aims to contribute to our understanding on rater beliefs and views and to promote transparency in rater’s work in the form of reflection. The paper focuses on professional Finnish raters’ beliefs and views of assessing L1 Estonian speakers in the criteria-referenced Finnish language test of the National Certifi- cates of Language Proficiency test system. Finnish raters (N = 27 were asked via email to shortly reflect on what they find easy and what difficult in rating Estonian speakers’ writing and speaking skills in the Finnish language test. The raters reflected on many issues which may or may not have direct influence in their rating thus bringing about assessment issues relating to reliability and validity: rating influenced by views and beliefs outside the established CEFR-based criteria. Content analysis was used to classify and organize the answers. Rater views highlighted the closeness of Estonian and Finnish cultures and language relations, which had both positive and negative impact on their attitudes. The raters regarded this closeness as a merit in that the test tasks and instructions were often easily understandable by the candidates and that the candidates appeared to be trained to taking tests, i.e. had considerable test-taking skills compared to candidates from more distant cultures. As the two languages are closely related, there is also considerable overlap between them, hence the raters pointed out that it was at times difficult to identify whether the candidates were speaking or writing Finnish or Estonian and more importantly whether this influences and should influence their assessment or not. There was negative interference in particular in words, idioms and grammar but in general mistakes made by these candidates were often minor and did not impede understanding.

Full Text Available Estonian dance history and traditions can in some respects be viewed as colonised culture. Folk dance research can help clarify which period or periods in our history could be discussed within the framework of colonialism. In this article, I analyse a style of staged folk dance, posing the question if a colonial situation came into being in Soviet-occupied Estonia in 1940 – 1991, and whether or not any colonial traits can be observed in Soviet Estonian cultural life and arts. The limits for what constitutes folk dance became extremely wide during the course of the 20th century, and came to encompass traditional as well as staged folk dances. The creation and performance of the latter became particularly popular in the days of the Estonian SSR. Looking at stylised dances performed at dance festivals or amateur concerts through the prism of post-colonialism could help find markers pointing to the colonial situation within the Soviet-era compositions. Stage and stadium performances at times share more similarities with classical ballet and character dance than with traditional dance – a situation which inspires to interpretations through Homi Bhabha’s notion of mimicry (Estonian: jäliendus; Annus 2003: 138–139. The style based on homogenization and other canons of classical dance has even after the re-independence of Estonia preserved the characteristics which came into being during the colonial period; out of the colonial interference, a new tradition has been born (for comparison, see Bhabha’s ’English book’. In post-colonial Estonia, the tradition of staged folk dances has little in common with folklore and a lot in common with performance arts. The hybrid art form which came into being mimicring a colonialising culture has its own – and if dance festivals are also taken into account – rather broad following of amateurs and spectators, in certain respects representing or wishing to represent the entire nation.

Context-Related Melodies in Oral Culture: An Attempt to Describe Words-and-Music Relationships in Local Singing Tradition

Directory of Open Access Journals (Sweden)

Taive Särg

2009-08-01

Full Text Available In oral folk song traditions we often find many lyrics, but not nearly as many melodies. The terms “polyfunctionalism”, “group melodies” or “general melodies” have been used by Estonian researches to indicate the phenomenon that many lyrics were sung to only one, or a small handful, of tunes. The scarcity of melodies is supposed to be one of several related phenomena characteristic to an oral, text-centred singing culture.In this article the Estonian folk song tradition will be analysed against a quantity of melodies and their usage in the following aspects: word-and-melody relationships and context-and-melody relationships in Karksi parish (south Estonia; a singer; and native musical terms and the process of singing and (recreation.

The determinants of employee participation in occupational health and safety management.

Science.gov (United States)

Masso, Märt

2015-01-01

This article focuses on employee direct participation in occupational health and safety (OHS) management. The article explains what determines employee opportunities to participate in OHS management. The explanatory framework focuses on safety culture and safety management at workplaces. The framework is empirically tested using Estonian cross-sectional, multilevel data of organizations and their employees. The analysis indicates that differences in employee participation in OHS management in the Estonian case could be explained by differences in OHS management practices rather than differences in safety culture. This indicates that throughout the institutional change and shift to the European model of employment relations system, change in management practices has preceded changes in safety culture which according to theoretical argument is supposed to follow culture change.

Benchmarking of Governmental Support Measures for University-Industry Cooperation

Directory of Open Access Journals (Sweden)

Kärt Rõigas

2013-01-01

Full Text Available This paper aims to benchmark Estonian governmental support measures targeted toward enhancing university-industry collaboration to European best practice and make suggestions for the development of these measures. The intensity and scope of university-industry cooperation support measures varies heavily in Europe. The survey of European University-Business Cooperation, Pro Inno Europe and Erawatch database of policy measures, and Community Innovation Survey reveal that Finnish, German and Austrian support systems are best balanced and provide good university-industry cooperation intensity. The cooperation measures in Estonia are weak and improvement should be made by increasing the Estonian governmental funding, mandatory cooperation in support measures, networking and applied research in universities, on-going application possibilities, reducing the bureaucracy, and improving the timing of measures.

Composition of Estonian atmosphere

International Nuclear Information System (INIS)

Punning, J. M.; Karindi, A.

1996-01-01

Atmospheric study, particularly that of its chemical composition, has a long tradition in Estonia. Since middle of this century, in addition to meteorological observations, some chemical compounds in precipitations have been regularly measured in many meteorological stations. The main aim was to acquire information about the state and dynamics of the atmosphere. Therefore, main attention was paid to monitoring chemical compounds which have a direct impact on the human environment. As energy production developed intensively and SO 2 and NO x increased drastically in the atmosphere in acidic rock areas, like Scandinavia, the problem of acid rain became the most important environmental problem in Europe and North-America. As a consequence, monitoring the compounds of sulphur in precipitation was organized in Estonia. In the 1970 s, as related to large operating oil shale-based power plants, Estonia became a country , where emissions of sulphur compounds per capita were extremely high. In 1979, Estonia became a participant in the European Monitoring and Evaluation Programme - the network created to study transboundary air pollution. The aims of the precipitation chemistry study and the related problems of the formation and transformation of the atmospheric composition have varied over the years. But monitoring of pollutant (in particular, sulphur compound) loads has been a central issue. Over recent years, an attempt was made to estimate the spatial regularities of atmospheric impurities and their impact on the pH of mean monthly precipitations. Furthermore, calculations were provided to find out the origin of atmospheric impurities washed out in Estonia. Until the 1990 s, CO 2 , and some other greenhouse gas (GHG) emissions were not studied in Estonia. The first inventory of GHG for Estonia was provided in 1995 using the Intergovernmental Panel on Climate Change (IPCC) methodology

The mean annual cycle during 1979–2000 for the site at 58.3° N and 26.5° E is compiled. The available ground-level data interpolated before TOMS, have been used for trend detection. During the last two decades, the quasi-biennial oscillation (QBO corrected systematic decrease of total ozone from February–April was 3 ± 2.6% per decade. Before 1980, a spring decrease was not detectable. No decreasing trend was found in either the late autumn ozone minimum or in the summer total ozone. The QBO related signal in the spring total ozone has an amplitude of ± 20 DU and phase lag of 20 months. Between 1987–1992, the lagged covariance between the Singapore wind and the studied total ozone was weak. The spring (April–May and summer (June–August total ozone have the best correlation (coefficient 0.7 in the yearly cycle. The correlation between the May and August total ozone is higher than the one between the other summer months. Seasonal power spectra of the total ozone variance show preferred periods with an over 95% significance level. Since 1986, during the winter/spring, the contribution period of 32 days prevails instead of the earlier dominating 26 days. The spectral densities of the periods from 4 days to 2 weeks exhibit high interannual variability.

Impact of porosity variation on diffusive transport: experimentation vs simulation

International Nuclear Information System (INIS)

Fatnassi, Ikram

2015-01-01

Reactions induced by the diffusion of reactants from different sources may alter rock confinement properties, and are therefore critical processes to assess short-term and long-term behaviour of rocks displaying a low permeability, such as argillites which are used as barriers in underground storage installation. In order to test transport-chemistry codes based on a continuous approach, the author of this research thesis reports the development and performance of simplest as possible experiments of sealing/dissolution diffusion, by using porous media of increasing complexity: compact sand, sintered glass, stoneware, chalk, until a material close to that envisaged within the frame of a storage like a Tournemire argillite. The principle of these experiments relies on the characterisation of the diffusive behaviour of an inert tracer within a porous medium submitted to dissolution reactions (attack of a carbonate matrix by an acid solution) and/or precipitation of mineral compounds (calcium oxalate, gypsum or barite) which results in an evolution of porosity and a modification of the diffusive transport of the studied tracer. At the end of the experiment, porous media and precipitates are characterised by SEM-EDS [fr

In this paper, the regression equations method for design of construction material was studied. Regression and polynomial equations representing the correlation between the studied parameters were proposed. The logic design and software interface of the regression equations method focused on parameter optimization to provide the energy saving effect at the stage of autoclave aerated concrete design considering the replacement of traditionally used quartz sand by coal mining by-product such as argillite. The mathematical model represented by a quadric polynomial for the design of experiment was obtained using calculated and experimental data. This allowed the estimation of relationship between the composition and final properties of the aerated concrete. The surface response graphically presented in a nomogram allowed the estimation of concrete properties in response to variation of composition within the x-space. The optimal range of argillite content was obtained leading to a reduction of raw materials demand, development of target plastic strength of aerated concrete as well as a reduction of curing time before autoclave treatment. Generally, this method allows the design of autoclave aerated concrete with required performance without additional resource and time costs.

Natural isotope tracing of hydric transfers in a very low porosity clay stone formation: the argilites of Tournemire (France)

International Nuclear Information System (INIS)

Moreau-Le Golvan, Y.

1997-01-01

Since 1988, the experimental site of the French Institute for Protection and Nuclear Safety Safety (IPSN) situated in a tunnel near Tournemire (Aveyron, France), is studied in order to develop techniques and methods for the characterization of water behaviour in a clay-stone formation with very low water content and very low permeability. Isotope geochemistry was used to define the fluid transfer modalities. After the development development of the improvement of sampling techniques, the measurement of the stable isotope contents (oxygen - 18, deuterium, carbon-13) and radioactive isotope contents (tritium, carbon-14, chlorine-36) of fluids (pore water, fracture water) and solids (calcite fracture fillings) allowed to distinguish several origins and behaviours of water in the massif. The stable isotope distribution of pore water could be due to a diffusion driven mixing between argillite formation water and water from karsts, over and underlying the argillite formation. In this hypothesis, the time needed to establish the distribution profile should be longer than 5 million years. The role of the fractures seems complex, with indications of local paleo-transfers from the matrix to the fracture, and indications of transfers from the karstic aquifer. (author)

ANALYSIS OF DEFORMABILITY OF ANISOTROPIC AGRILLITE CLAYSTONES

2017-08-01

Full Text Available In the paper, the results of deformability study of agrillite claystones are used for determination of the Jointed rock model parameters. The number of stamp, pressuremeter and compressive tests allowed to research anisotropic deformability of argillite claystone in vertical and horizontal direction. The following problems were solved during the study: 1 the in-place and laboratory experiments to calculate the anisotropy coefficient were done for anisotropic agrillite claystones with both natural moisture and total water saturation; 2 the deformation parameters were determined and the numerical simulation of the stress-strain state of claystone in field tests was carried out with the use of Plaxis 2D software application; 3 the comparative analysis was done for calculated claystone deformation and the values obtained during the in-place tests. The authors proved that agrillite claystones shows two times less deformation under loading in the horizontal direction than vertically. The ratio is obtained to determine the parameters for numerical simulation of the Jointed Rock model used as a practical tool for analysis of stress-strain behavior of anisotropic soils. The authors provided a recommended practice for consideration of specific properties of argillite claystones when carrying out foundation works.

An experimental study of electrical and dielectric properties of consolidated clayey materials

Comparon, L.

2005-06-01

This study is devoted to the electrical and dielectric properties of consolidated clays. A better understanding of the conduction and polarization phenomena in clays is necessary to better interpret in situ measurements in terms of water saturation and texture. An experimental study was carried out on synthetic clay samples (kaolinite and smectite) compacted with various water contents, porosities and mineralogical compositions, on a large frequency range, using three laboratory setups. The electrical properties of natural argillites (from ANDRA) were then investigated. We found that the response of the synthetic samples is mainly controlled by water content on the whole frequency range; two polarization phenomena were observed, which were related to the Maxwell-Wagner polarization and the electrical double layer polarization around the clay particles. The electrical response of argillites is more complex; it is controlled by water content but also by the microstructure of the rock. In these rocks, the electrical and dielectric anisotropies are high; anisotropy was also measured for the synthetic clays. The existing models explain the high frequency limit of the dielectric permittivity of the clayey materials, but the low frequency part of the spectra (≤1 MHz) needs theoretical developments.

2012-01-01

A scientific program has been especially established to better understand the high-pH fluids / clay interactions through a mineralogical and geochemical study of three engineered analogues available by means of the IRSN Tournemire experimental platform. This platform, located in Aveyron (France), is based on a tunnel, excavated between 1882 and 1886 through Domerian marls and Toarcian argillites, and is dedicated since 1990 to multidisciplinary research programs. Different contexts presenting the argillite formation in contact with a cementitious material are encountered and are linked to its historical construction and scientific evolution. These rare examples of cement / clay contacts maintained over time scales ranging from a few years to a hundred of years are studied as engineered analogues of a deep geological storage. This approach is moreover completed by experiments (diffusion and advection) performed in laboratory over shorter time and smaller space scales in order to discriminate and control the major parameters involved in such interactions (details are given in another paper). This paper presents the scientific program developed on the three engineered analogues: tunnel walls recovered by lime after excavation; four concreted exploration boreholes; two experimental research galleries excavated in 2003

Would it be possible that as Bach does not need to be interpreted within the context of German music or Pärt within the context of Estonian music, works of literature relate to each other within the global field of literature and are no longer related to their linguistic and cultural contexts? In order to come to a „bigger picture“, to achieve a more extensive level of generalization, might it be possible to give up the linguistic, historical and cultural contextualization of works of literature? What would a small literature win or lose in such situation? In the present article the concept of world literature and its’ historical conditions – as an object of comparative literary studies – will be explained using the example of Estonian literature. In order to do so, an overview of the history of comparative literary studies at the University of Tartu will be provided. At the University of Tartu, the study of comparative literature was initiated much earlier than systematic study of Estonian literature or its�

model also examines the reaction of nitrate with Fe(II) minerals present in the COx, which have the potential to reduce nitrate. This results in the oxidation of Fe(II) and the intermediate formation of Fe(III) minerals, which provide electron acceptors which are subsequently reduced by organics. The model has examined the case where the nitrate affected system returns to a reduced state resulting from continued input of acetate. In this scenario sulphate reduction develops in the COx, By considering the concentration of electron donors and acceptors for the major redox couples the GRM calculates a redox potential. Further results will be presented, of the spatial and temporal distributions in reactive species, minerals and microbial biomass related to the coupling of microbial kinetics, under the influence of advective and diffusive transport. The results will be discussed and interpreted to assess the potential significance of environmental factors that may control microbial growth and the mediation of redox conditions in argillite host rocks.

phenomenon.” The notion of “regional phenomenon” is problematic here because the definition of a region is arbitrary and several definitions of the region in question are possible. That is why the following question arise: 1. Is the concept of the “Baltic States” (in the meaning of Estonia + Latvia + Lithuania as it is presented here the only possibility or are other regional divisions thinkable? 2. If there really is one Baltic regional identity or unity, can this also be seen in the interaction between these countries and cultures, e.g. in the number of mutual translations? Is the interaction among the three larger than with others? In dealing with the first question it is stressed that the concept of a “Baltic area” is less stable than assumed, and in previous centuries other regions than only Estonia, Latvia and Lithuania were regarded as “Baltic”. In the Middle Ages, when the concept “Baltic” first emerged in the writings of Adam of Bremen (11th century, even Denmark could be part of the “Baltic area”. Later, one can still find concepts where Finland and Poland are part of the “Baltic area” (cf. Kaslas 1976. And indeed, a closer look on the Finnish-Estonian relations on the one hand and the Polish-Lithuanian relations on the other hand reveals that these relationsships are certainly at least as strong as those between the so called Baltic states. As research on this topic has been carried out earlier (e.g. Kurman 1972, this question is, however, not investigated here in any great detail. The second question is divided into two subquestions: How many writers have been translated into the two other languages, and how many have been translated into the languages of the other neighbours? In order to find answers to these questions, all 300 writers have been examined from the viewpoint of translations into other languages. First of all, how are they translated into the two other “Baltic” languages, i.e.: How many Estonian writers are

Full Text Available "User-friendly corpus sentence: Parameters for automatic selection" he paper presents how corpus sentences can be used in learners’ lexicography and in data-driven language learning. There are two methods for the automatic selection of corpus sentences suitable for language learners: machine learning methods and rule-based methods. The paper focuses on the rule-based methods and describes them through the example of a tool called GDEX (Good Dictionary Example (Kilgarriff et al. 2008. GDEX helps automatically select sentences suitable for language learners. It takes into account certain parameters: sentence and word length, threshold of low frequency words, keyword position, the absence and presence of certain words etc. The paper introduces the parameters of Estonian GDEX configuration and discusses which parameters need to be studied further. The paper also introduces the new corpus EstonianNC GDEX, aimed at language learners. The corpus contains only sentences that meet the requirements for Estonian GDEX configuration. In the sentences there are no low frequency words, vocabulary is controlled (no slang, vulgarisms or profanities occur, and all sentences are full sentences and contain verbs. At the moment, the new corpora is accessible only in the corpus query system Sketch Engine (Kilgarriff et al. 2004. In future, it will be possible to integrate it into dictionary portals aimed at language learners.

Post-Socialist Fathers ‘At Home’ and ‘Away from Home’ in ‘Old Europe’: Facing the Challenge through Masculine Identity Talk

Directory of Open Access Journals (Sweden)

Marion Pajumets

2012-06-01

Full Text Available This article focuses on those Estonian male migrants to ‘Old Europe’ who spend most of their time in the domestic realm as caring fathers and supportive spouses to their wives, who are meanwhile advancing their transnational careers. In this context, masculine identity talk can be understood in terms of strategies employed in response to the challenge to the men’s masculinity that this atypical life choice is likely to entail. Identity is viewed in this article as a processual phenomenon that is relentlessly, although not always deliberately, (reformulated in discourse, rather than determined by the assigned social roles. Analysis of in-depth interviews reveals that there are varied discourses in use that efficiently reconstruct the interviewees’ sense of personal significance. Interestingly, men predominantly combine ‘alternative’ discourses (‘caring father’, ‘supportive spouse’, ‘civilised adult’, which potentially undermine Estonian idealised masculinity, with the ‘conservative’ discourses (‘professional man’, the ‘well-off’, that reinforce the Estonian male norm. Men draw on a range of potentially oppositional and conflicting resources for constructing masculinity, without much reflexive selection from their part. Hence, the discourses men engage in position the men as much as the men appear to consciously position themselves in the discourses. This poststructuralist account of identity is located within a more structural historical context of transition and change in contemporary Europe.

Individualisation of Migration from the East? Comparison of Different Socio-Demographic Groups and their Migration Intentions

Directory of Open Access Journals (Sweden)

Maarja Saar

2016-12-01

Full Text Available Recent studies on Eastern European migration argue that moving for self-development reasons is becoming increasingly common among this group. Furthermore, it is suggested that migration from the East is becoming individualised and less dependent on social surroundings. Nevertheless, most such results rely on interviews conducted among certain social groups, such as the young and highly skilled. Hence, the comparison between different social groups and their motivations is rarely provided and, therefore, the claims about increased individualisation might be premature. This article uses the Estonian Household Module Survey, including responses from 620 Estonians intending to migrate, to evaluate if migration flows are indeed becoming more individualised and less dependent on social surroundings. Using cluster analysis, three different groups — self-development, economic and life quality migrants — are formed, which are then tested using regression analysis to check for the influence of socio-demographic variables. The article concludes that socio-demographic variables such as gender, age, ethnicity, family status and socio-economic status are still relevant for migration intentions. Indeed, a new group of Eastern European migrants, mainly oriented towards self-development, is emerging; however, it is small and consists mostly of young, Estonian-speaking females. The results complicate the notions of free mobility and liquid migration from Eastern Europe and illustrate that there is a need to pay attention to the increasing group differences in these societies

Geostatistical characterization of the Callovo-Oxfordian clay variability: from conventional and high resolution log data

International Nuclear Information System (INIS)

Lefranc, Marie

2007-01-01

Andra (National Radioactive Waste Management Agency) has conducted studies in its Meuse/Haute-Marne Underground Research Laboratory located at a depth of about 490 m in a 155-million-year-old argillaceous rock: the Callovo-Oxfordian argillite. The purpose of the present work is to obtain as much information as possible from high-resolution log data and to optimize their analysis to specify and characterize space-time variations of the argillites from the Meuse/Haute-Marne site and subsequently predict the evolution of argillite properties on a 250 km 2 zone around the underground laboratory (transposition zone). The aim is to outline a methodology to transform depth intervals into geological time intervals and thus to quantify precisely the sedimentation rate variation, estimate duration; for example the duration of bio-stratigraphical units or of hiatuses. The latter point is particularly important because a continuous time recording is often assumed in geological modelling. The spatial variations can be studied on various scales. First, well-to-well correlations are established between seven wells at different scales. Relative variations of the thickness are observed locally. Second, FMI (Full-bore Formation Micro-Imager, Schlumberger) data are studied in detail to extract as much information as possible. For example, the analysis of FMI images reveals a clear carbonate - clay inter-bedding which displays cycles. Third, geostatistical tools are used to study these cycles. The vario-graphic analysis of conventional log data shows one metre cycles. With FMI data, smaller periods can be detected. Variogram modelling and factorial kriging analysis suggest that three spatial periods exist. They vary vertically and laterally in the boreholes but cycle ratios are stable and similar to orbital-cycle ratios (Milankovitch cycles). The three periods correspond to eccentricity, obliquity and precession. Since the duration of these orbital cycles is known, depth intervals can
