    To understand the phenomenon of consumption of surrogate and illegal alcohols in Tallinn, capital of Estonia. This study, conducted in Tallinn in May 2006, used rapid situation assessment. Interviews with key informants in relevant settings such as emergency departments of hospitals, accommodation for the homeless, police etc. (n = 22), with alcohol abusers (n = 33), natural observations of surrogate sale and consumption venues (n = 46), and tracking of trade data were carried out. Key informants confirmed that consumption of illegal and surrogate alcohols are widely used by alcohol abusers, a finding confirmed by the alcohol abusers. Availability of surrogates varied by area of the city, mainly sold from street kiosks. Illegally produced spirits were also easily available. Sales of surrogates appear to have increased in recent years. A range of alcohol-containing substances that appear to be easily available at low cost, and that have high concentration of ethanol or contaminants known to be toxic, were identified in Tallinn. Alcohol policies in Estonia should address the consumption and availability of these substances.

  3. Environmental innovation through transport policy. The implementation of the free fare policy on public transport in Tallinn, Estonia

    Urban areas are of increasing relevance when it comes to sustainability: First, about half of the world’s population now lives in cities (increasing to 60% by 2030). Second, cities are nowadays responsible for levels of resource consumption and waste generation that are higher beyond their share on world population. Third, cities are more vulnerable to disruptive events that can lead to restrictions on the provision of resources and to changes on the environment caused by climate change. And fourth, because they concentrate key resources (political, social, cultural…), cities are seen as strategic scenarios where to experiment and develop solutions to cope with the prevailing sustainability challenges driven by the major social and environmental transformations. Urban agglomerations can be seen as complex innovation systems where human activities are shaped in order to transform societies towards sustainable development. For this paper, we focus on the case of an environmental innovation regarding transport policy, the implementation of the fare-free policy on public transport for all inhabitants of Tallinn, Estonia. Tallinn, with 414,000 inhabitants in 2015, is the capital of Estonia and the largest city in the country. Over the last two decades the share of public transport trips decreased dramatically. After a public opinion poll in 2012, in which over 75% of the participants voted for a fare-free public transportation system (FFPTS) in Tallinn, the new policy was implemented on 1st January 2013. From that date on inhabitants of Tallinn could use all public transport services (busses, trams, trolly-busses) operated by city-run operators for free. Later the fare-free system was implemented also on trains within Tallinn. In this paper we analyze the context, in which this policy was implemented, the main characteristics of its implementation and its actual situation. (Author)

    1999-09-01

    The Estonian Country Case Study concentrated on the energy sector. Estonia is in the process of intensive transition from a centrally planned to a market economy. The reforming of the whole economy, included the energy sector, is underway at present in Estonia, therefore the current situation is permanently changing. This in its turn complicates the overall characterisation of the situation and makes it difficult to have well founded basis for furhter forecasts and projections. However, the main lines of further development have been worked out in the governmental document `Long Term Development Plan for the Estonian Fuel and Energy Sector`, which was adopted by the Parliament (Riigikogu) in February 1998. The Estonian Country Case Study team has managed with the complicated task to analyse the most probable GHG mitigation options to be used for the period up till 2035. MARKAL and MARKAL-MACRO models were used to build up the energy system development scenarios and to analyse various GHG mitigation options. Two main scenarios, respectively with low and high GDP growth rates, were assumed for the present analysis. Also the impact of carbon tax on the choice of possible energy generation scenarios was studied with the help of the model. The results have been discussed in the context of future socio-economic and political restrictions. Special attention was paid to the problems and prospects of using Estonian main energy resource - oil shale - for the production of electricity. New combustion technologies developed in Estonia allow reducing CO{sub 2}, SO{sub 2} and NO{sub x} emissions, which makes them highly important in the process of following the binding agreements of international treaties on pollution abatement. The technological mitigation options of GHG emissions have been handled thoroughly, as they are of great interest for Estonia following the requirements of the Kyoto conference. Additionally, renewable energy sources were discussed more thoroughly

    This paper examines challenges obtaining representative samples of males who have sex with males (MSM) in Estonia and provides descriptive HIV behavioral data gathered from four cross-sectional surveys; three using the internet, and one using respondent driven sampling (RDS) to recruit MSM in Tallinn and Harju County. Estonian MSM were sampled between March and May in 2004 (n=193), August and November in 2005 (n=146) and September and December in 2007 (n=238) using internet websites. MSM in Tallinn and Harju County were sampled between April and June in 2007 (n=59) using RDS. Recruitment of MSM using RDS did not acquire the calculated sample size. The RDS study reached a less diverse group of MSM than did the internet studies which recruited a larger proportion of MSM who were older, bisexual, having female sexual partners during the last six months, and unlikely to have been tested for HIV. The findings and observations presented in this paper could inform researchers in Estonia, and the region, about the efficacy of and socio-cultural challenges to sampling MSM to collect HIV biological and/or behavioral data.

    Full Text Available Abstract Recent data suggest that globally, between 5% and 10% of all new HIV cases are the result of unsafe injecting practices, and experts agree that reducing these practices is key to tackling the spread of HIV. And yet, despite the overwhelming evidence that providing sterile syringes to injection drug users (IDU through syringe exchange programs (SEPs or other means is an effective way of reducing HIV transmission among high-risk subpopulations, IDU in most settings still do not have access to sterile injecting equipment or if they do, access remains too restricted to effectively reduce the risk of HIV transmission. Vorobjov and colleagues have presented in this journal an interesting and timely study from Estonia comparing individuals who obtain syringes from SEPs and those who obtain syringes from pharmacies. As the authors point out, Estonia faces an unacceptably high HIV incidence rate of 50 new HIV cases per 100,000, this rate driven primarily by injection drug use. As such, the authors argue that Estonia's SEP network does not have the capacity to serve a growing IDU population at risk of transmitting HIV and pharmacy dispensation of clean syringes may be one potential approach to decreasing syringe sharing among high-risk injectors. It may be overly optimistic to consider the impact of higher threshold interventions such as pharmacy-based SEPs, given that IDU populations that engage in HIV risk behaviours such as syringe sharing are often hidden or hard to reach. Despite the need for a cautious approach, however, the findings presented by Vorobjov et al. may chart one potential course towards a more comprehensive societal response to reducing the health harms associated with injection drug use.

    On November 9-10, 1998 ALTENER Conference Energy from Waste and Biomass took place in the hotel Pirita, Tallinn, Estonia. The Conference was organized by the Swedish National Energy Administration in co-operation with the FEMOPET Estonia and the South Jutland University Centre, Biomass Institute (Denmark). The main topics of the Conference were: collecting biogas from landfall, biogas from municipal sewage treatment, biogas from animal manure, waste heat, biomass from the pulp industry and the sawmill, biomass from forestry, biomass for local and district heating. More than 200 delegates from 14 countries participated in this event. A poster exhibition and two study tours to Paeaeskuela Landfill Plant and Jueri Boiler House were organised too. (author)

  9. Ethnic Russian Minority in Estonia

    2016-12-01

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

    2003-01-01

    First PET scans in Estonia were performed on 25th November 2002 in North Estonia Regional Hospital, Tallinn. Six patients with melanoma underwent scanning with FDG. This event was a result of thorough extensive preparations first started in 2000 during the European Association of Nuclear Medicine congress in Paris. During the congress first contacts were made with providers of mobile PET units. At the same time negotiations were begun with potential FDG suppliers. For the introduction of PET in Estonia mobile truckmounted scanning technology was chosen due to low level of initial investments. Of particular importance was also availability of maintenance personnel from the device providers. A significant prerequisite was potential availability of FDG from the neighbourhood - Finland and Sweden. The latter avoided the necessity for investments into local cyclotrons and local FDG production. For the first scanning experience the dedicated truckmounted PET-camera Accel, Siemens was brought by the International Hospital Group (IHG, Amersfoort, Netherlands). The device arrived by ferry from Stockholm to Tallinn harbour at 10 o'clock in the morning and left by ferry for Helsinki at 23 o'clock. The team-on-truck consisted of one technician for device operation, two drivers and two company representatives. North Estonia Regional Hospital provided three additional technicians for patient preparation and FDG injection, one nuclear medicine doctor and one specialist of biomedical engineering and medical physics. The FDG was provided by MAP Medical Technologies, Schering, Helsinki, Finland. The shipments were made by air. This was possible due to small distance between Tallinn and Helsinki of approximately 80 km due to the regular flight connections between the two cities. The FDG was shipped in two lots with a time interval of 4 hours. The patient selection was based on clinical and histopathology data. In all six patients the exam was justified for detailied staging and

    2010-05-01

    Full Text Available In the article home languages, their qualities and use by pupils in grades 2 to 5 in Tallinn are analyzed. Two larger and more characteristic groups (Ukrainians and Belarusians and two groups with Islamic backgrounds (Azerbaijanis and Tatars were compared with the aim of analysing different language loss and preservation factors. Although Ukrainians and Belarusians form much larger ethnic groups within Estonia, they have not managed to preserve their language anywhere near as successfully as the Azerbaijanis and Tatars. Comparison of the data suggests that language preservation in Estonia and the ability to withstand Russification are most influenced by the degree of difference of the language from Russian and the religious difference from the Russian Orthodox faith (and Soviet era atheism. Home languages are characterised by their use mainly in the verbal form, with skills in the literary language generally low or even non-existent. Languages are for the most part learned informally, primarily through communication with parents and/or grandparents. The result is a supersaturated vernacular with a large degree of variation and loans from superstratum languages which falls far from the standard of the language in question.DOI: http://dx.doi.org/10.5128/ERYa6.15

  4. Towards sustainable Estonia

    1997-01-01

    Since 1989 the Estonian Green Movement has had a working group on energy issues. This group has tried to influence the energy policy in Estonia towards sustainable development. But the process has been hard. Five years have passed since Estonia has started with taking on its shoulders international environmental obligations. Unfortunately, Estonia is one of the last countries in Europe still to join the obligation on transboundary pollution. A master plan on energy is now prepared in Estonia within the framework of PHARE programme, involving quite a few high level specialists from various institutions in Estonia and assisted by foreign specialists. But the energy sector has not been open to public discussion in Estonia up to now. It's very important not to lose from sight the environmental problems in connection with energy sector development plans. The Estonian Green Movement together with its umbrella organization, the Friends of the Earth Europe, have worked out a new energy strategy for Estonia, based on the concept of environmental space. This concept has been used by some countries already on working out the strategy for their economic progress. The limit values for a set of basic mineral resources and local fuels of Estonia have been calculated on the basis of environmental space and economic targets set for the year 2010

  5. Design of accounting curriculum: The case of Estonia

    Directory of Open Access Journals (Sweden)

    Alver Lehte

    2014-01-01

    Full Text Available The process of globalization sets new requirements for the professional qualification of accountants and auditors. In the business world globalized investment market demands consistent high quality financial information across borders; investors are looking for a global accounting profession to provide it. There is more pressure on accounting professionals to expand and enhance their knowledge, skills, and abilities beyond what they are currently likely to possess. Providers of accounting education must take into account the changed world and create contemporary curricula. In Estonia the change from a command to a market economy has inevitably influenced not only the accounting framework but also the entire system of accounting education. It is clear that without a design of accounting curricula it is practically impossible to fulfill requirements of nowadays high quality financial information. Tallinn University of Technology (TUT holds on the advanced level of accounting education the leading position in Estonia. The accounting curriculum (on the graduate level as well as undergraduate level is the most popular among all curricula at the Tallinn School of Economics and Business Administration of TUT. It is a joint system, which consists of undergraduate and graduate degree programs. Small sub specializations: for example in financial accounting, managerial cost accounting, taxation and auditing become evident while interpreting the graduate and undergraduate programs as one united system. The paper explains a new model of accounting curriculum developed at TUT as well as its educational philosophy and principles of designing. It also describes conditions required for development and continuous improvement of competitive curriculum.

  6. Data Envelopment Analysis of Helsinki-Tallinn Transportation Chains

    Olli-Pekka Hilmola

    2013-12-01

    Full Text Available The Baltic Sea shipping is at a crossroads as sulphur regulation will lead to excessive cost increases from the year 2015 onwards and CO2 emission trading is planned to be implemented for the entire shipping sector within the EU area. Therefore, shipping is going to be minimized and hinterland transportation (road and rail will act as substitute. This research analyzes the situation on one of the highest volume general cargo transportation routes of Finland (operating between Helsinki, Finland and Tallinn, Estonia, including loading and unloading at seaports and short sea shipping activity in between. Based on the efficiency evaluation results, it seems that containers should be favoured over semi-trailers – containers could be carried efficiently either in container ships or even at currently favoured RoRo or RoPax ships. Our research illustrates that pure container shipping with larger container ships within the analyzed route is not entirely out of question, but lead time and hinterland operations should receive more attention. Alternatively, RoRo and RoPax ships can also do something to increase their competitiveness in environmental harm caused and diesel consumption – higher cargo loads and utilization levels are short-term key for continued dominance.

  7. How important is business ethics: evidence from Estonia

    Full Text Available How important is business ethics: evidence from Estonia During recent decades, more and more attention has been paid to business ethics. There seems to be an increasing interest in the non-financial aspects of business. Stakeholders all over the world express their concern about embedding the principles of professional and business ethics into companies’ everyday activities. The main subject of this research is business ethics and the purpose is to find out the im-portance of professional and business ethics and determine its place in the modern business world as seen by Estonian business students and practitioners. To achieve the goals, the authors conducted a survey among Estonian graduate and undergraduate accounting and business students at Tallinn University of Technology and Estonian business practitioners. 587 responses were collected in the process. This infor-mation was compiled and analyzed based on status, gender, age, and specialization. The survey revealed that in Estonia people are familiar with business ethics; however, it is not of great interest to them. The results also indicate that professional and business ethics merit more attention and should be included as a required course in the curriculum of Higher Education Institutions (HEIs. In general, business ethics in Estonia was not ranked as “high”, which was also the case for both professional ethics at the work-place/university and also the importance and necessity of ethics in the modern business world.

    This review of Estonia is the first environmental performance review (EPR) carried out under the auspices of the ECE Committee on Environmental Policy. This pilot ECE study builds, inter alia, on the experience gained in the preparation of pilot environmental performance reviews of Poland and Bulgaria, which were carried out in 1994-1995 by OECD in cooperation with ECE. The report focuses on capacity building; air, water, waste, and nature management; the integration of environmental and economic policies both generally and more specifically within the energy sector; and cooperation of Estonia with the international community. The review examines the current situation, recent and likely future trends, pressures, policy responses and their effectiveness. The principal conclusions and recommendations for improving Estonia's environmental performance are brought together in the concluding chapter.

  9. Container transport direct call – logistic solution to container transport via Estonia

    Directory of Open Access Journals (Sweden)

    A. Tolli

    2007-12-01

    Full Text Available Container transport in the world grows up to 12 % every year. Chinese container transport contributes majority of container flows in international container transport. Many world seaports compete for Chinese container flows and make eff orts to get investments and direct calls from China to their ports. Estonia has a possibility to decrease its large dependence and risks due to the transit of oil and oil products and coal with the help of container flows from China. In addition to a favorable geographical location Estonia has several other important arguments, like suffi cient land in the harbours for developing a container terminal to launch extensive container transport transit from China. Port of St. Petersburg, container transport port closest to Estonia by the Baltic Sea, is overloaded. Estonia can compete for container flows directed to Moscow, Nizhniy Novgorod, Kazan and Kaluga. Construction of an international high-tech container terminal in Port of Tallinn serves as one important precondition for directing Russian transit container flows through Estonia. Such a container terminal could service also larger vessels and container flows from China. Container lines and container terminals operating as alliances are jointly able to substantially increase container flows through countries.

  10. Gas development plan - Estonia

    International Nuclear Information System (INIS)

    1994-06-01

    The total supply of natural gas to Estonia is provided by the Russian company ''Lentransgas'', a 10 year contract is under negotiation. The gas transmission system is physically a part of the transmission network in the Baltic region which previously operated as an integral part of the USSR gas transmission system. The potential market is too small to justify investment in an alternative pipeline from the North Sea. The general reduction in purchasing power in the former COMECON countries has resulted in a decreased industrial production in Estonia and lead to a steep decline in natural gas consumption in all sectors except households. The Danish firm ''Dansk Olie og Naturgas A/S'' has been requested to assist the Estonian company ''AS Eesti Gaas J.S.C.'' in preparing a gas development plan for Estonia. Phase 1 of this plan aims to provide a detailed description of the status of the existing situation under the headings of gas supply and demand, transmission and distribution, economy and organization. The most important problems related to the current transition of the Estonian gas sector towards operation under market conditions are addressed, focussing on gas supply and market conditions, flow control and metering. The general organization of the gas sector in Estonia is described and possible models for future organization are discussed. Some recommendations are given and areas in need of further investigation are identified. (AB)

  12. University courses on radiation protection in Estonia

    International Nuclear Information System (INIS)

    Realo, Enn

    1999-01-01

    A brief overview is given on the educational courses containing topics in the field of radiation protection in the Tallinn Technical University and in the University of Tartu, Estonia. It follows from the analysis that at present there is no complete system for education or training of experts in the field. At the same time a significant deficit in specialists and experts is one of the major barriers in the development of an efficient radiation protection infrastructure in this country. A comparison of the course topics to the syllabus for the training of qualified experts recommended by EC and by IAEA demonstrates the items, which need a further development and an expanded coverage in the existing or in future courses. These items involve, e.g., operational radiation protection and its organisation, waste management, transport, quality assurance, etc. Upgrading of courses for the missing theoretical items is not difficult, but it is not sufficient. The largest void lies in the weakness / absence of an adequate basis for practical work or exercises for students. The examples of co-operation and help provided for the existing courses, especially by the Nordic countries, are encouraging. (au)

    The compulsory vaccination of pets, the recommended vaccination of farm animals in grazing areas and the extermination of stray animals did not succeed in eliminating rabies in Estonia because the virus was maintained in two main wildlife reservoirs, foxes and raccoon dogs. These two species became a priority target therefore in order to control rabies. Supported by the European Community, successive oral vaccination (OV) campaigns were conducted twice a year using Rabigen® SAG2 baits, beginning in autumn 2005 in North Estonia. They were then extended to the whole territory from spring 2006. Following the vaccination campaigns, the incidence of rabies cases dramatically decreased, with 266 cases in 2005, 114 in 2006, four in 2007 and three in 2008. Since March 2008, no rabies cases have been detected in Estonia other than three cases reported in summer 2009 and one case in January 2011, all in areas close to the South-Eastern border with Russia. The bait uptake was satisfactory, with tetracycline positivity rates ranging from 85% to 93% in foxes and from 82% to 88% in raccoon dogs. Immunisation rates evaluated by ELISA ranged from 34% to 55% in foxes and from 38% to 55% in raccoon dogs. The rabies situation in Estonia was compared to that of the other two Baltic States, Latvia and Lithuania. Despite regular OV campaigns conducted throughout their territory since 2006, and an improvement in the epidemiological situation, rabies has still not been eradicated in these countries. An analysis of the number of baits distributed and the funding allocated by the European Commission showed that the strategy for rabies control is more cost-effective in Estonia than in Latvia and Lithuania.

    A report is provided of an accident and an incident involving radioactive sources in Estonia. In the 1994 occurrence, looters of a depository of radioactive waste manipulated a source containing 137 Cs and received dangerous doses of radiation. One of the persons involved died, others suffered minor burns. Another event, which occurred in early 1995, did not have a tragic outcome: an abandoned 137 Cs source was found in the vicinity of the highway linking Tallinn and Narva and was disposed of safely. Both these accidents draw attention to the potential dangers caused by the insufficient survey of the territory, radiation protection structures not yet fully operable, and the lack of equipment and know-how. The lessons to be drawn from these events are considered on the basis of the chronologies and factual data. The report contains concise descriptions of the accidents, a medical overview of the fate of the injured persons and the lessons learned from these accidents. (author)

    The situation of women in education, work, and research in Estonia is relatively good. Nevertheless, science (especially engineering) remains a male-dominated field. The total number of female scientists and engineers in the workforce is about two-thirds that of males. Moreover, the gender imbalance in the researcher population increases with age. Significant pay-gap and power imbalances between the genders remain both in Estonian society in general and in the fields of science and technology. In many practical situations, behavior of both men and women is still guided by gender stereotypes.

    Long life practice has proved that small hydropower is not a beaten track in the global energy field. Before the Second World War small hydropower was rather well developed in Estonia as well. Being neglected during the years of Soviet occupation, it is rather important to help it to regain its position in the Estonian energy system once again. Our hydropower potential is not big, but it has got a good established position as an energy saving measure. By now we have some good examples of restored hydropower stations on commercial basis to be optimistic about the future

    The purpose of this paper is to discuss the alternative environmental management options for the utilisation of municipal solid waste (MSW) incineration fly ash (FA), which is generated at Iru Power Plant where MSW is incinerated in Estonia. To determine sustainable and economically feasible environmental management options for MSW incineration FA in Estonia, CO 2 sequestration with a further carbonation process was examined. A partial Cost & Benefit Analysis has been conducted to compare the carbonation process to the current situation. Two carbonation options were developed. Option 1 is to use carbonated FA in any other processes based on the waste-to-product principle. Option 2 is to send carbonated FA to the non-hazardous landfill in Tallinn, Estonia. Important parameters, such as Net Present Value (NPV), Internal Rate of Return (IRR), Benefit-Cost Ratio (BCR) and Break Even Point (BEP), have been calculated for carbonation options and the current case. In addition, a sensitivity analysis has been conducted to examine its robustness. The results showed that the best option is carbonation Option 1 with NPV of 9,209,662 EUR, IRR of 43%, BCR of 2.63 and BEP between 2018 and 2019. Both Options 1 and 2 constitute more sustainable and environmentally friendly management options compared to the current situation. It can be concluded that this preliminary feasibility study showed that running a carbonation plant may be profitable and sustainable for Estonia. Currently, there is no treatment technology for MSW incineration FA in Estonia and FA is sent to a neighbouring country for further utilisation. This is the first study to demonstrate FA management options with economic and environmental benefits.

    1996-11-01

    The project `Inspection of Pipelines in Estonia` was funded by Danish government and was carried out in collaboration between DONG, Balslev and FORCE. By agreement between Eesti Gaas and DONG, the pipeline system between Kohtla-Jaerve and Tallinn was selected for inspection. This pipeline system has a total length of 176.9 km. The objective of the project has been, based on detailed inspection of relative short lengths of pipe, to determine the integrity of the pipeline and to give advice concerning the continued use as a high pressure transmission pipeline. The objectives have been met as set out by the project Proposal with the investigation and this report as follows: Based on a document review together with the measurements and observations in the field and in the laboratory, the condition of approximately 5 km of the pipeline has been evaluated; Recommendations are given in this report with the aim of extending the life of the pipeline. A further objective has been to provide know-how transfer in order to permit Eesti Gaas to run similar inspections on other parts of their transmission system. (EG)

  6. Method for Pedestrian Crossing Risk Assessment and Safety Level Determination: the Case Study of Tallinn

    2016-07-01

    Pedestrians are a part of vulnerable road users which safety requires a special attention. Official statistics in Estonia from the last decade returns the following numbers: around 30 % of all road traffic accidents in the country were accidents with pedestrians, 32 % of all traffic fatalities were finished with pedestrian death. Pedestrian crossing has the biggest risk level between all kinds of pedestrian facilities, because it includes a direct conflict point between vehicle and pedestrian traffics. The article presents a method to assess risk of pedestrian crossing users and to determine safety level of this road infrastructure element. This approach is based on observation and collection of infrastructural as well as traffic data, which includes: (1) information about each pedestrian crossing facility, its location and state, (2) data about accidents with pedestrians and their features, (3) data from road traffic measurements. The main advantages of the described method are universality and comprehensiveness. The case study was done in Kristiine district of the city Tallinn, which was chosen as the most typical average district of Estonian capital. Results of this study are also presented in the article.

    This analysis of the Estonian health system reviews recent developments in organization and governance, health financing, health-care provision, health reforms and health system performance. Without doubt, the main issue has been the 2008 financial crisis. Although Estonia has managed the downturn quite successfully and overall satisfaction with the system remains high, it is hard to predict the longer-term effects of the austerity package. The latter included some cuts in benefits and prices, increased cost sharing for certain services, extended waiting times, and a reduction in specialized care. In terms of health outcomes, important progress was made in life expectancy, which is nearing the European Union (EU) average, and infant mortality. Improvements are necessary in smoking and alcohol consumption, which are linked to the majority of avoidable diseases. Although the health behaviour of the population is improving, large disparities between groups exist and obesity rates, particularly among young people, are increasing. In health care, the burden of out-of-pocket payments is still distributed towards vulnerable groups. Furthermore, the number of hospitals, hospital beds and average length of stay has decreased to the EU average level, yet bed occupancy rates are still below EU averages and efficiency advances could be made. Going forwards, a number of pre-crisis challenges remain. These include ensuring sustainability of health care financing, guaranteeing a sufficient level of human resources, prioritizing patient-centred health care, integrating health and social care services, implementing intersectoral action to promote healthy behaviour, safeguarding access to health care for lower socioeconomic groups, and, lastly, improving evaluation and monitoring tools across the health system.

    Full text: In Estonia first radiosynovectomy (RSE) was carried out in 2001 at Tallinn Central Hospital, which has remained the only institution in North Estonia performing these procedures. Purpose of this study was to analyze the results and the clinical experience gained during the period of September 2001 January 2005. We performed RSE in 10 knee joints of 7 patients. Our patient population consisted of 3 males and 4 females (mean age 34, range 16-48). There were 6 patients with rheumatoid arthritis (RA) and chronic synovitis and 1 patient with haemophilia (HE) who had one episode of haemarthrosis eight month prior to RSE. In RA the duration of the disease was ranging from 2 month to 20 years. All RA patients were resistant to anti-inflammatory drugs, immunosuppressants and intraarticular steroid therapy. Prior to RSE, conventional rheumatologic evaluation and MRI scan were carried out, revealing the thickness of synovia of 2-5 mm, and minimal or no cartilage damage. In our HE patient chronic hypertrophic synovitis associated with haemarthrosis did not respond to haematological treatment: replacement of the missing clotting factor, intermittent steroids, immobilization, physical therapy. According to MRI, the thickness of synovia was patchy, 5-26 mm, the cartilage damage was absent. For RSE, intraarticular injection of radiocolloid was carried out in aseptic conditions and under local anesthesia. Treated joints were immobilized for 2 days. In 5 out of 6 RA patients the injection was performed once, in one RA patient four times. In order to minimize local inflammation and lymphatic clearance glucocorticoids were administered together with radioisotope agents. In three patients (2 with RA and 1 with HE) 27 mCi of 166-Ho-FHMA was injected, and in remaining four patients with RA - 4-6 mCi of 90-Y radiocolloid was used. All joints with Ho-FHMA were checked for radiocolloid leakage by subsequent gamma camera imaging. Treatment response was evaluated from 2 to 6 month

  17. Efficiency Assessment of Support Mechanisms for Wood-Fired Cogeneration Development in Estonia

    Science.gov (United States)

    Volkova, Anna; Siirde, Andres

    2010-01-01

    There are various support mechanisms for wood-fired cogeneration plants, which include both support for cogeneration development and stimulation for increasing consumption of renewable energy sources. The efficiency of these mechanisms is analysed in the paper. Overview of cogeneration development in Estonia is given with the focus on wood-fired cogeneration. Legislation acts and amendments, related to cogeneration support schemes, were described. For evaluating the efficiency of support mechanisms an indicator - fuel cost factor was defined. This indicator includes the costs related to the chosen fuel influence on the final electricity generation costs without any support mechanisms. The wood fuel cost factors were compared with the fuel cost factors for peat and oil shale. For calculating the fuel cost factors, various data sources were used. The fuel prices data were based on the average cost of fuels in Estonia for the period from 2000 till 2008. The data about operating and maintenance costs, related to the fuel type in the case of comparing wood fuel and oil shale fuel were taken from the CHP Balti and Eesti reports. The data about operating and maintenance costs used for peat and wood fuel comparison were taken from the Tallinn Elektrijaam reports. As a result, the diagrams were built for comparing wood and its competitive fuels. The decision boundary lines were constructed on the diagram for the situation, when no support was provided for wood fuels and for the situations, when various support mechanisms were provided during the last 12 years.

  18. Role of environment in strengthening competitiveness of cities by example of European Green Capitals and Tallinn

    2014-01-01

    Full Text Available Guaranteeing a high-level living environment is one of the most important preconditions to the balanced and sustainable economic and social development of the European Union. Serious environmental problems can be seen in European cities, which are the places where most of the population live and which create the highest number of jobs, economic growth and added value. The level of urbanisation in Europe was 72.7% in 2010 and the UN forecast that it will increase to 82.2% by 2050. The European Green Capital Award was created in 2006 in order to recognise cities that have contributed to the improvement of their quality of life. The cities that have won the award have started using the most innovative and efficient measures for increasing the city’s competitiveness, and are an example of how to achieve sustainable development for all cities, not just capitals. The environmental indicators of cities that have won the European Green Capital Award are high. In this article the problem is analysed using the example of Tallinn, the capital of Estonia, which strives for a place among cities with the highest quality of life in Europe. The objective of this article is to analyse the areas of the city’s environmental activities and environmental organisation in the context of increasing competitiveness. The original database used by the author in this article consists of the responses given by the governments of the cities who have already been awarded the title of European Green Capital when asked to describe the impact that applying for and achieving the title had on their cities

    Full Text Available New data on the Fennoscandian Shield and the Baltic area suggest a need for reinterpretation of the stratigraphy of Estonian Precambrian rock complexes. The rocks of the Tallinn Zone formed in the framework of the Fennian orogeny at the margin of the Bergslagen microcontinent 1.90–1.88 Ga ago. The precise age of the Alutaguse Zone is not known. It may have formed either during the 1.93–1.91 Ga Lapland–Savo orogeny or as a rifted eastern part of the Tallinn Zone in the Fennian orogeny. The granulites of western and southern Estonia belong to the volcanic arcs inside the 1.84–1.80 Ga Svecobaltic orogenic belt and show peak metamorphic conditions of 1.78 Ga. Small shoshonitic plutons formed 1.83–1.63 Ga, the small granitic plutons of the Wiborg Rapakivi Subprovince 1.67–1.62 Ga, and the Riga pluton 1.59–1.54 Ga ago.

    All post-Soviet countries are trying to reform their primary health care (PHC) systems. The success to date has been uneven. We evaluated PHC reforms in Estonia, using multimethods evaluation: comprising retrospective analysis of routine health service data from Estonian Health Insurance Fund and health-related surveys; documentary analysis of policy reports, laws and regulations; key informant interviews. We analysed changes in organisational structure, regulations, financing and service provision in Estonian PHC system as well as key informant perceptions on factors influencing introduction of reforms. Estonia has successfully implemented and scaled-up multifaceted PHC reforms, including new organisational structures, user choice of family physicians (FPs), new payment methods, specialist training for family medicine, service contracts for FPs, broadened scope of services and evidence-based guidelines. These changes have been institutionalised. PHC effectiveness has been enhanced, as evidenced by improved management of key chronic conditions by FPs in PHC setting and reduced hospital admissions for these conditions. Introduction of PHC reforms - a complex innovation - was enhanced by strong leadership, good co-ordination between policy and operational level, practical approach to implementation emphasizing simplicity of interventions to be easily understood by potential adopters, an encircling strategy to roll-out which avoided direct confrontations with narrow specialists and opposing stakeholders in capital Tallinn, careful change-management strategy to avoid health reforms being politicized too early in the process, and early investment in training to establish a critical mass of health professionals to enable rapid operationalisation of policies. Most importantly, a multifaceted and coordinated approach to reform - with changes in laws; organisational restructuring; modifications to financing and provider payment systems; creation of incentives to enhance

  12. Estonia 2013: Energy Policies Beyond IEA Countries

    Energy Technology Data Exchange (ETDEWEB)

    NONE

    2013-08-01

    One of the fastest-growing economies in the OECD, Estonia is actively seeking to reduce the intensity of its energy system. Many of these efforts are focused on oil shale, which the country has been using for almost a century and which meets 70% of its energy demand. While it provides a large degree of energy security, oil shale is highly carbon-intensive. The government is seeking to lessen the negative environmental impact by phasing out old power plants and developing new technologies to reduce significantly CO2 emissions. The efforts on oil shale complement Estonia’s solid track record of modernising its overall energy system. Since restoring its independence in 1991, Estonia has fully liberalised its electricity and gas markets and attained most national energy policy targets and commitments for 2020. It has also started preparing its energy strategy to 2030, with an outlook to 2050. Estonia is also promoting energy market integration with neighbouring EU member states. The strengthening of the Baltic electricity market and its timely integration with the Nordic market, as well as the establishment of a regional gas market, are therefore key priorities for Estonia. Following its accession to the Organisation for Economic Co-operation and Development (OECD) in 2010, Estonia applied for International Energy Agency (IEA) membership in 2011. This review of Estonia’s energy policies is part of the IEA accession process. It analyses the energy policy challenges and opportunities facing Estonia, and provides critiques and recommendations for future policy improvements. It is intended to guide the country towards a more secure and sustainable energy future.

The author analyses the reasons on such a volatile economic growth pattern and explains economic cycle management particularities in Estonia. In the frames of macroeconomic developments will be analyzed monetary and fiscal policies. The author argues, that Estonia’s fiscal policy has been always pro-cyclical, what has deepened country’s macroeconomic volatility.

  9. Childhood deaths from external causes in Estonia, 2001–2005

    Directory of Open Access Journals (Sweden)

    2007-07-01

    Full Text Available Abstract Background In 2000, the overall rate of injury deaths in children aged 0–14 was 28.7 per 100000 in Estonia, which is more than 5 times higher than the corresponding rate in neighbouring Finland. This paper describes childhood injury mortality in Estonia by cause and age groups, and validates registration of these deaths in the Statistical Office of Estonia against the autopsy data. Methods The data on causes of all child deaths in Estonia in 2001–2005 were abstracted from the autopsy protocols at the Estonian Bureau of Forensic Medicine. Average annual mortality rates per 100,000 were calculated. Coverage (proportion of the reported injury deaths from the total number of injury deaths and accuracy (proportion of correctly classified injury deaths of the registration of causes of death in Statistical Office of Estonia were assessed by comparing the Statistical Office of Estonia data with the data from Estonian Bureau of Forensic Medicine. Results Average annual mortality from external causes in 0–14 years-old children in Estonia was 19.1 per 100,000. Asphyxia and transport accidents were the major killers followed by poisoning and suicides. Relative contribution of these causes varied greatly between age groups. Intent of death was unknown for more than 10% of injury deaths. Coverage and accuracy of registration of injury deaths by Statistical Office of Estonia were 91.5% and 95.3%, respectively. Conclusion Childhood mortality from injuries in Estonia is among the highest in the EU. The number of injury deaths in Statistical Office of Estonia is slightly underestimated mostly due to misclassification for deaths from diseases. Accuracy of the Statistical Office of Estonia data was high with some underestimation of intentional deaths. Moreover, high proportion of death with unknown intent suggests underestimation of intentional deaths. Reduction of injury deaths should be given a high priority in Estonia. More information on

    During last 100-150 years global climate has changed significantly. Climate warming has also observed in Estonia. The aim of this paper is to analyse how different are old climate normals calculated for 1881-1880 from present-day normals (1966-1998). The new normals are calculated for monthly and annual mean air temperature at 22 stations in Estonia. Mean monthly and annual precipitation totals and snow cover duration are found at 69 stations and observation sites. Significant differences were determined between the old and new averages. As a rule, air temperature has increased while 0.4 deg C in case of annual values. Snow cover duration has decreased during this century. Its new normals are lower by 5-10 days, what is a direct consequence of climate warming

    The aim of the current survey was to investigate the complementary self-treatment of the common cold and flu with medicinal plants among pharmacy customers in Estonia. A multiple-choice questionnaire listing 10 plants and posing questions on the perceived characteristics of cold and flu, the effectiveness of plants, help-seeking behaviour, self-treatment and sources of information, was distributed to a sample of participants in two medium size pharmacies. The participants were pharmacy customers: 150 in Tallinn (mostly Russian speaking) and 150 in Kuressaare (mostly Estonian speaking). The mean number of plants used by participants was 4.1. Of the respondents, 69% self-treated the common cold and flu and 28% consulted with a general practitioner. In general, medicinal plants were considered effective in the treatment of the above-mentioned illnesses and 56% of the respondents had used exclusively medicinal plants or their combination with OTC medicines and other means of folk medicine for treatment. The use of medicinal plants increased with age and was more frequent among female than male respondents. Among Estonian-speaking customers lime flowers, blackcurrant and camomile were more frequently used, and among Russian speaking customers raspberry and lemon fruits. Regardless of some statistically significant differences in preferred species among different age, education, sex and nationality groups, the general attitude towards medicinal plants for self-treatment of the common cold and flu in Estonia was very favourable.

  20. BOOKSELLER AS A CULTURAL AGENT: BOOK TRADE IN ESTONIA IN THE SECOND HALF OF THE 19TH AND AT THE BEGINNING OF THE 20TH CENTURY

    Directory of Open Access Journals (Sweden)

    Jantson, Signe

    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

    Full text: In the recently published 'Europe's Environment' (1995) one can find the map on 1 37C s cumulative deposition in Europe after the Chernobyl accident (source: De Corte et al., 1990). On this map most of the Eastern Europe including Baltic Sea region is practically uncovered. In this reason we decided to present data on accumulation of 1 37C s in the forest ecosystems in Estonia. Field sampling for current study has been conducted in 1986 - 1994. 1 37C s concentrations were measured in different compartments of model trees, ground vegetation layers, debris and topsoil. The amount of 1 37C s varied from 1.9 kBq/m 2 in continental Estonia to 28.8 kBq/m 2 in north-eastern Ne part of Estonia. The results obtained correspond to data presented in Wahlstroem et al., (1992) for Finland. According to the 'Europe's Environment' criteria northeastern Estonia belongs to the third cumulative deposition zone (10 to 32 kBq/m 2 ). In Estonia the total deposition of 1 37C s varies in the range from practically zero to 3.9 kBq/m 2 . The calculations of Realo et al. (1994) back to May 1, 1986 gave figures from 0 to 21 kBq/m 2 . In macro lichens Cetraria, Cladina, Cladonia the rapid changes in 1 37C s concentrations were observed: 0.06 - 0.18 kBq/kg in 1982-85, 0.93 - 6.23 kBq/kg in 1986-87, 0.27 -4.26 kBq/kg in 1988-89, 0.05 - 1.46 kBq/kg in 1990-91 and, finally, 0.03 - 0.46 kBq/kg in 1993-94. At the end of the observation period average value of the 1 37C s concentrations was the same as maximum before the CRA and decline of the concentrations was 4 times during six years. Average concentrations of 1 3 7 C s in two common forest mosses Pleurozium shreberi and Hylocomium splendens was 0.43 kBq/kg of dry matter and in forest debris 0.38 kBq/kg. In 1986 the highest concentration in mushrooms - 16.6 kBq/kg was found in Lactarius sp. (Martin, L., et al., 1991). In 1991 samples of 41 different mushroom species from 63 sample sites mostly in Scots pine stands were analyzed. The

    In Estonia, electricity from renewable sources is mainly promoted through a feed-in premium tariff. In addition, investment supports are available for specific types of renewable energy production technologies. To encourage the use of renewable energy sources for heating, investment supports are made available for the construction of CHP plants, as well as for private consumers. In transport, the use of renewable energies is currently mainly encouraged through a support scheme to promote the purchasing of electric cars that use power produced from renewable energy sources (RES Legal Europe, 2014)

    2012-11-01

    Full Text Available This article examines trends in the labour market position, defined in terms of three dimensions – earnings, perceived job security and overall job satisfaction – among four population groups in Estonia – Estonian men and women and Russian-speaking men and women. We explore how the labour market position these groups changed between 1993 and 2008. We used data from 1993 and 2008, collected in the population survey Work, Family and Leisure, designed by the Institute of International and Social Studies at Tallinn University. We carried out a two-step analysis: first, we conducted descriptive analysis to explore changes in the labour market situation of men and women of two ethnic groups in the period of 1993-2008; and second, we used models of multivariate analysis of variances to examine how gender, ethnicity and occupational status as well as the intersection of these variables are related to earnings, job security and job satisfaction.We found that Estonian men have emerged as the most successful group in the labour market, while the labour market position of Russian-speaking women is the most disadvantaged compared to other groups in terms of earnings, job security and job satisfaction. We suggest that these labour market inequalities could be increasing, and that the interaction of gender and ethnicity might become increasingly important in shaping labour market outcomes.

    The Raman spectra of 9,10-anthraquinone (AQ) and 9,10-anthraquinone-d/sub 8/ are examined. Raman band assignments are made from this data and from a published normal coordinate analysis. The Raman spectra of AQ at 5K is reported and vibrational assignments for the phosphorescence spectra of AQ in n-hexane at 4.2 K are reexamined in light of new 3 B 1 /sub g/ → 1 A/sub g/ phosphorescence data. Contrary to previous work from this laboratory, it is concluded that although higher order vibronic interactions may be operative between the two closely spaced 3 A/sub u/- 3 B 1 /sub g/ electronic states, these interactions are not manifested in the phosphorescence spectra of AQ in n-hexane at 4.2 K

    The largest commercially exploited oil shale deposit in the world is in northeast Estonia. The accumulation of solid residues by oil shale mines and processing plants has resulted in numerous dumps and ash hills, which are polluting the environment. The groundwater and streams are highly polluted by sulphates, phenols and oil products. A dump hill of radioactive wastes poses a serious threat to the Baltic Sea. Local people suffer from diseases more often than in other regions of Estonia. (author)

    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)

The anthraquinone unit is located about a crystallographic center of inversion. Each asymmetric unit therefore contains one MnII atom, two water ligands and one half AQTC4− anion. The MnII atom is coordinated in a distorted octahedral geometry by four O atoms from three AQTC4− ligands and two water O atoms. Two of the carboxylate groups coordinate one MnII atom in a chelating mode, whereas the others each coordinate two MnII atoms. Each AQTC4− tetra-anion therefore coordinates six different MnII ions and, as a result, a three-dimensional coordination polymer is formed. O—H...O hydrogen bonds, some of them bifurcated, between water ligands and neighboring water or anthraquinone ligands are observed in the crystal structure.

    2014-05-01

    Full Text Available The relationships between the frequency and duration of thunderstorms, lightning and southern cyclones over Estonia are presented for the period 1950–2010. A total of 545 southern cyclones and 2106 thunderstorm days were detected, whereas 11.3% of the observed thunder days were associated with southern cyclones. At the same time, 29.2% of all southern cyclones were accompanied by thunderstorms. In the thunder season, however, this percentage was much higher, reaching up to 80% in summer months. The number of thunder days was largest when the centres of southern cyclones passed a measuring station at a distance less than 500 km. The number of cloud-to-ground lightning strikes related to southern cyclones was larger than that of any other thunder events. The results of our study demonstrate that the intensity of thunderstorms related to southern cyclones is higher than that of other thunderstorms. Correlation analysis revealed statistically significant relationships between the frequency of thunder days related to southern cyclones and the frequency of southern cyclones, also between the frequency of thunder days related to southern cyclones and days of other thunder events.

  11. Tax wedge in Croatia, Belgium, Estonia, Germany and Slovakia

    Full Text Available The aim of this paper is to analyse the taxation of labour income in Croatia, Belgium,Estonia, Germany and Slovakia. Having presented an outline of tax system rules, the paper shows the decomposition of the net average tax wedge for different family types and different income levels based on the OECD methodology. The results show that all observed countries apply a progressive tax schedule, apart from Germany where taxation for higher gross wages is not progressive due to a  cap on the SIC base. When it comes to a taxpayer earning an average gross wage, a Croatian single worker without children has the lowest tax burden, followed by Estonia, Slovakia, Germany and Belgium. However, as regards taxpayers earning 400% of AGW, Estonia has the smallest tax wedge, followed by Slovakia, Germany, Croatia and Belgium. Similar results are obtained by analyzing the tax wedge for couples with two children where one spouse is out of work.

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

    International Nuclear Information System (INIS)

    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.

    2009-12-01

    Full Text Available Gravity data in Estonia have been collected by different institutions over many decades. This study assesses the suitability of available gravity data for ensuring a 1 cm geoid modelling accuracy over Estonia and in the Baltic Sea region in general. The main focus of this study is on the determination and elimination of discrepancies between three nationwide datasets. It was detected that one tested historic gravity dataset contained inadmissible systematic biases with respect to other tested datasets. Possible ways of gravity data improvement are discussed. More specifically, new field observation campaigns and aspects of using their outcomes in subsequent regional geoid modelling are suggested.

    According to the data of the Estonian Statistics Department the consumption of fuels in Estonia over the period of January-June 1993 was a follows: coal 77,053 t, oil shale 7,981,840 t, fuel peat 127,376 t, peat briquette 42,041 t, firewood 154,511 solid metres, wood chip 55,648 solid metres. The consumption of fuel peat (chiefly for producing briquette) was more considerable in the town of Kohtla-Jaerve and in the districts of Paernu and Tartu where Estonia's major peat-briquette plants are located. The share of peat in the other industries has been less significant. (author)

    2010-01-01

    The full photoreduction of 1-nitro-2-R-9,10-anthraquinone (R = H: N1, methyl: N2) was studied in benzene, acetonitrile and acetonitrile-water mixtures in the presence of 2-propanol and triethylamine (TEA). The major photoproduct is the fluorescing 1-amino-2-R-AQ (A1, A2). The quantum yield of full reduction increases with the donor concentration, approaching Φ NH 2 =0.1. The intermediates involved are assigned on the basis of spectral and kinetic characteristics. The short-lived triplet state (≤20 ns) of N2 can be intercepted by 2-propanol or TEA, thereby forming the spectroscopically hidden donor radicals and the nitroAQ radicals which absorb at 400 and 540 nm; the latter band is due to the radical anion. The triplet state of N1 was not observed at room temperature, but the radical properties and decay in the nitrosoAQ are similar for N1 and N2. For donors in lower concentrations Φ NH 2 is strongly increased in the presence of benzophenone, acetophenone or acetone, approaching 0.22. The results under direct and sensitized conditions are compared and major dependences and the effects of mixtures of acetonitrile with water are outlined.

For donors in lower concentrations {Phi}{sub NH{sub 2}} is strongly increased in the presence of benzophenone, acetophenone or acetone, approaching 0.22. The results under direct and sensitized conditions are compared and major dependences and the effects of mixtures of acetonitrile with water are outlined.

    A new 8-ionized hydroxylated 9,10-anthraquinone namely, 1-hydroxy-3-methyl-9,10-anthraquinone-6-O-β-D-glucopyranoside-8-olate (Rumpictuside A, 1) along with five known flavonoids, apigenin 7-O-β-D-glucoside (2), vitexin (3), quercetin 3-O-β-D-glucouronide (4), orientin (5), and isorientin (6) were isolated from Rumex pictus. The structures of isolated compounds were identified by the extensive spectroscopic techniques such as, UV, FT-IR, 1D, 2D NMR and HR-FAB-ESI-MS. The ionized hydroxyl group in the new anthraquinone (1) was rarely found for anthraquinone glycosides isolated from natural sources. All the isolated compounds were found inactive against influenza A virus infection. Compounds 2-6 exhibited significant antioxidant activity against DPPH and ABTS + . The alcoholic extract exhibited moderate activity while the new anthraquinone 1 showed the lowest activity against both assays. Copyright © 2017 Elsevier Ltd. All rights reserved.

    Full Text Available Abstract Background Family doctors should care for individuals in the context of their family. Family has a powerful influence on health and illness and family interventions have been shown to improve health outcomes for a variety of health problems. The aim of the study was to investigate the Estonian family doctors' (FD attitudes to the patients' family-related issues in their work: to explore the degree of FDs involvement in family matters, their preparedness for management of family-related issues and their self-assessment of the ability to manage different family-related problems. Methods A random sample (n = 236 of all FDs in Estonia was investigated using a postal questionnaire. Altogether 151 FDs responded to the questionnaire (response rate 64%, while five of them were excluded as they did not actually work as FDs. Results Of the respondents, 90% thought that in managing the health problems of patients FDs should communicate and cooperate with family members. Although most of the family doctors agreed that modifying of the health damaging risk factors (smoking, alcohol and drug abuse of their patients and families is their task, one third of them felt that dealing with these problems is ineffective, or perceived themselves as poorly prepared or having too little time for such activities. Of the respondents, 58% (n = 83 were of the opinion that they could modify also relationship problems. Conclusions Estonian family doctors are favourably disposed to involvement in family-related problems, however, they need some additional training, especially in the field of relationship management.

    Full Text Available Background . Home care (HC is placed between the health and social welfare systems, and the clients of HC mostly need health services. Along with other providers, family doctors (FDs are usually involved in the provision of care. Objectives. This paper aims to describe and compare the involvement of HC providers to elderly and disabled persons in Poland and Estonia. Material and methods . This study is part of the international project EURHOMA P (Mapping Professional Home Care in Europe. Data was collected in 2008–2010. Experts from different areas of health and social care were queried by using a questionnaire containing structured case narratives, which were hypothetical descriptions of the situations of elderly or disabled persons living at home and in need of care. Results. There are a number of HC services, e.g. nursing, medical and social, available in both countries. The application for HC is mostly made by the patient or a close family member; the point of entry to HC can differ and depends on the client’s primary problem. FDs, together with social workers, play an important role in the provision of HC services in both countries. However, due to a shortage of round-the-clock professional services at a client’s home, families are also expected to play a large role in providing HC . Conclusions . Health care professionals, mainly those working in primary health care, play a remarkable role in access to and provision of HC services. Nevertheless, responsibility for 24-hour care lies, to a large extent, with the client’s immediate family. This situation seems to be typical in Eastern European countries.

    Mosses Pleurozium schreberi and Hylocomium splendens have been proposed as biomonitors of atmospheric heavy metals. These mosses are wide-used in biomonitoring studies in Scandinavia as well as in other Nordic countries. Some methodical problems of bryoindication, e.g. other factors than the adsorption of precipitation which influence element concentrations in mosses have been studied in Scandinavia as well. Methodical study for determining the intrasite, local variability in Estonia was started in 1991. Despite of the used uniform methodics in sampling, cleaning, digesting and chemical analysing of moss samples in the same laboratory there is high variability of the content of elements at the reference area. There are many reasons for this variability - errors from instrumental procedures (analytical steps in chemical analysing), biological deviation, etc. In this article the results of the methodical study of intrasite variability of As, Cd, Cr, Cu, Fe, Ni, Pb, Zn and V in mosses at reference areas of different deposition level in Estonia are presented. The intrasite variability of elemental content in mosses at the reference areas is taken into account in mapping the territorial distribution of the content of elements in mosses, samples of which were collected during the joint Finnish-Estonian-Russian biomonitoring project in 1992 in a more dense network compared with the 1989 and 1990 national moss surveys in Estonia in order to describe more accurately the pollution situation in highly polluted north-eastern Estonia

    Full Text Available The oldest surviving helmet from Estonia is a 13th-century kettlehat found near village of Kodasoo in northern Estonia. Three samples from different parts of the kettlehat were investigated in a metallographic study. The raw material of the Kodasoo kettlehat was a slag-rich iron of heterogeneous carbon content. It was improved by folding and forge-welding it at least three times, resulting in layered structure with more uniformly distributed carbon content.

    El casco más antiguo encontrado en Estonia es un «chapel de fer» del siglo XIII que proviene de cerca de la aldea de Kodasoo, en el Norte de Estonia. Tres muestras de diversas partes del casco fueron investigadas mediante un estudio metalográfico. El material original del casco de Kodasoo era un hierro de contenido de carbono heterogéneo y con abundantes inclusiones de escoria. Se intentó mejorar su calidad mediante forja, doblándolo y soldándolo a la calda por lo menos tres veces, dando como resultado una estructura estratificada, con el contenido de carbono distribuido más uniformemente.

    To identify the composition of illegal and surrogate alcohol products consumed in Estonia. The initial source of information was a series of visits made in August 2005 to a soup kitchen in central Tartu, Estonia. Individuals were asked for brief details of their personal circumstances, what they normally drank, and in addition they were asked to bring samples of the substances they usually consumed. In other cases, the substances identified were purchased by the investigators or from informal contacts in north-eastern part of Estonia, an area that is well known for illegal alcohol consumption. Samples were tested for chemical contents. We identified a range of alcohol-containing substances that are consumed, although, not intended for consumption. These comprised medicinal products, aftershaves, illegally produced spirits, and fire-lighting fuel. The medicinal compounds contained, on average, 67% ethanol by volume; the aftershaves contained slightly less. Both were typically pure, with a few containing detectable quantities of isoamyl alcohol. The illegally produced alcohol contained, on average, 43% ethanol by volume, ranging from 32 to 53%. However, many also contained detectable quantities of long chain alcohols. These substances are half the price or less of commercial vodka, with fire lighting fuels especially inexpensive. There is in Estonia a range of alcohol-containing substances easily available at low cost. Some contain substantially higher concentrations of ethanol than commercial spirits and others also contain toxic long chain alcohols.

  14. Economically viable and environment-friendly hydro energy in Estonia

    International Nuclear Information System (INIS)

    Saks, Ants; Velner, Harald

    2001-01-01

    Hydro energy has been in oblivion in Estonia for about 30 years now. During the 1960s, most of Estonia's small hydropower plants were closed down, just as it was done in the whole Soviet Union. As the only larger hydro plant, the 125 MW plant in Narva, was situated on the Russian side of the Narva River, there were only two or three small hydro plants left. Even those were exploited at low capacity and mainly for heating the buildings. It was not until the 1990s that a number of enthusiasts started to re-establish the hydro plants by reconstructing old installations. The pre-feasibility study 'Hydropower in Estonia' proposed by Estonian and Swedish experts, showed that the restoration of the hydropower plants and watermills is economically feasible and technically possible if advanced technology is used. Hydropower as an alternative ('green') energy source should be used in the best technical-economical way. The first pilot plant in Estonia, the 200 kW Kamari plant was constructed in 1998 with compact-propeller units, in co-operation with Waterpumps WP Oy and ABB. Today, ten new plants have been constructed or are under construction. Hydropower plants/watermills should be reconstructed in accordance with the legislative acts on environment protection

    expulsion of over 200 scholars from Soviet Russia in the year 1921. A special place is accorded in this article to the role of Russian emigrants in Estonian culture, including the role played by Russian cultural figures (scholars, military personnel, artists, etc. in building up the young Estonian Republic. The most active participation of Russians was occasioned by the creation of Estonia’s own legal system. In addition, Russians participated in organizing the Estonian postal system and local transportation. The role of Russian emigrants in the development of the educational system of the Estonian Republic is also significant. The article describes the leadership provided by the local Russian community, particularly in the establishment in 1924 of the tradition of Russian cultural festivals, which was then disseminated globally in Russian exile culture. Brief consideration is given to local Russian culture and its importance in the development of Estonian culture. The most important facet of this was the Estonian ballet, born of Russian traditions and experience. Reportedly the first professional ballet troupe was assembled in Tallinn in 1918 by Sessy Smironina-Sevun, but the first actual ballet was performed in 1922, premiering with Coppelia, choreographed by the Moscow Bolshoi Ballet prima ballerina Viktorina Krieger, who played the lead role, and was later to be the artistic director of the Estonia ballet. In 1919, Jevgenia Litvinova, a former ballerina from the Maria Theatre, founded the first ballet studio in Tallinn. Another topic addressed in the article is local publishing and literary activity in the Russian language. Besides Russian publishing houses (Bibliofiil, Koltso, Alfa, Russkaja Kniga, Estonian-language publishing houses printed Russian-language books, textbooks, magazines and newspapers. Up to the year 1940, 91 publishing houses in Estonia printed Russian-language material, many of them only a few Russian books. In addition to publication activities

    The conformational analyses of 9, 10-dihydroanthracene and several of its methylated and ethylated derivatives are studied by empirical force field calculations (MM2 and MMPI). The computational results are considered in light of previous and current carbon NMR data. Model compounds are examined which involve fixed, planar, and boat-shaped conformations about the central ring, and these /sup 13/C NMR data are then compared with flexible systems. It is concluded that carbon chemical shifts and carbon-hydrogen coupling constants are consistent with the results of molecular mechanics calculations which indicate a greater tendency for planarity around the central ring than previously considered.

    The influences on the mixing properties of GaAs Schottky diodes containing an organic 3,4,9,10-perylenetetracarboxylic dianhydride layer were investigated. The frequency conversion ability of the devices was determined by considering the I-V characteristics and high frequency reflection parameters by using a mixing technique operated in the microwave range. The results show that an organic layer with 20 nm thickness enhances the diode conversion gain for mixing applications by 3 dB and lowers the device operating bias voltage by 0.1 V. This process is related to the specific properties of the organic semiconductor and resulting organic-inorganic interface

    The energetic effects caused by replacing one of the methylene groups in the 9,10-dihydroanthracene by ether or ketone functional groups yielding xanthene and anthrone species, respectively, were determined from direct comparison of the standard (p o = 0.1 MPa) molar enthalpies of formation in the gaseous phase, at T = 298.15 K, of these compounds. The experimental static-bomb combustion calorimetry and Calvet microcalorimetry and the computational G3(MP2)//B3LYP method were used to get the standard molar gas-phase enthalpies of formation of xanthene, (41.8 ± 3.5) kJ . mol -1 , and anthrone, (31.4 ± 3.2) kJ . mol -1 . The enthalpic increments for the substitution of methylene by ether and ketone in the parent polycyclic compound (9,10-dihydroanthracene) are -(117.9 ± 5.5) kJ . mol -1 and -(128.3 ± 5.4) kJ . mol -1 , respectively.

    Measurements of fusion for 9,10,11 Be allow testing of the relative importance to fusion and breakup of the α-cluster structure found in all these Be isotopes, compared with the neutron-halo structure only present for 11 Be. However, disagreements exist among different published experimental data sets for the reactions of 9,10,11 Be with 209 Bi. Accurate measurements of above-barrier cross sections for the products of complete fusion (fission and evaporation residues) in the reaction of 9 Be with 209 Bi and 208 Pb provide the basis for a reanalysis of above-barrier fusion for 10,11 Be+ 209 Bi. This includes procedures making full use of the higher precision stable beam data and resolves many of the disagreements. The improved self-consistency of the analysis allows investigation of the experimental average fusion barriers. Although showing some scatter, these suggest a higher barrier for the neutron halo nucleus 11 Be. Comparison of published cross sections for fusion associated with capture of all the charge of the projectile suggest that all these Be isotopes show significant suppression of complete fusion, a surprising result given that the α-breakup threshold energies are 1.57 MeV for 9 Be but over 7 MeV for 10,11 Be. Further experimental studies to investigate in more detail the division between complete and incomplete fusion for reactions of 10,11 Be are needed.

    Four novel conjugated polymers (P1-4) with 9,10-disubstituted phenanthrene (PhA) as the donor unit and 5,6-bis(octyloxy)benzothiadiazole as the acceptor unit are synthesized and characterized. These polymers are of medium bandgaps (2.0 eV), low-lying HOMO energy levels (below -5.3 eV), and high hole mobilities (in the range of 3.6 × 10(-3) to 0.02 cm(2) V(-1) s(-1) ). Bulk heterojunction (BHJ) polymer solar cells (PSCs) with P1-4:PC71 BM blends as the active layer and an alcohol-soluble fullerene derivative (FN-C60) as the interfacial layer between the active layer and cathode give the best power conversion efficiency (PCE) of 4.24%, indicating that 9,10-disubstituted PhA are potential donor materials for high-efficiency BHJ PSCs. © 2014 WILEY-VCH Verlag GmbH & Co.

    To document the prevalence of overweight, obesity and thinness in 9-10 year old children in Mauritius. 412 boys and 429 girls aged 9-10 years from 23 primary schools were selected using stratified cluster random sampling. All data was cross-sectional and collected via anthropometry and self-administered questionnaire. Outcome measures were BMI (kg/m2), prevalence of overweight, obesity (International Obesity Task Force definitions) and thinness (low BMI for age). Linear and logistic regression analyses, accounting for clustering at the school level, were used to assess associations between gender, ethnicity, school location, and school's academic performance (average) to each outcome measure. The distribution of BMI was marginally skewed with a more pronounced positive tail in the girls. Median BMI was 15.6 kg/m2 in boys and 15.4 kg/m2 in girls, respectively. In boys, prevalence of overweight was 15.8% (95% CI: 12.6, 19.6), prevalence of obesity 4.9% (95% CI: 3.2, 7.4) and prevalence of thinness 12.4% (95% CI: 9.5, 15.9). Among girls, 18.9% (95% CI: 15.5, 22.9) were overweight, 5.1% (95% CI: 3.4, 7.7) were obese and 13.1% (95% CI: 10.2, 16.6) were thin. Urban children had a slightly higher mean BMI than rural children (0.5 kg/m2, 95% CI: 0.01, 1.00) and were nearly twice as likely to be obese (6.7% vs. 4.0%; adjusted odds ratio 1.6; 95% CI: 0.9, 3.5). Creole children were less likely to be classified as thin compared to Indian children (adjusted odds ratio 0.3, 95% CI: 0.2, 0.6). Mauritius is currently in the midst of nutritional transition with both a high prevalence of overweight and thinness in children aged 9-10 years. The coexistence of children representing opposite sides of the energy balance equation presents a unique challenge for policy and interventions. Further exploration is needed to understand the specific causes of the double burden of malnutrition and to make appropriate policy recommendations.

    Evaluation of the pathomorphological characteristics of cases involving natural and sudden cardiovascular death is essential for the determination of the cause of death. The main purpose of this study is to investigate sudden unexpected cardiovascular death and to study how different geographical climatic influences may affect cardiac mortality in three capitals: Budapest, Vilnius and Tallinn. There were 8482 (5753 male, 2729 female) cardiovascular deaths between 2005 and 2009. The highest rate was observed in the age group between 71 and 80 years (35.17%) and 51-60 years (24.45%). The highest number of cardiovascular deaths occur in January (805/9.49%) and December (770/9.07%). Seasonal distribution was observed, with winter prevalence in Tallinn (279/3.20%) and spring prevalence in Vilnius (760/8.90%). Though in Vilnius and Budapest a great number of deaths occurred in winter and spring, any correlation with other factors (e.g. age, gender, BAC) was not statistically significant. Based on our results we can conclude that environmental-geographical parameters may affect natural cardiovascular death. Examination of pathological patterns and predisposing environmental parameters may help to improve prevention strategies. Copyright © 2013. Published by Elsevier Ltd.

    Full Text Available A series of cationic dyes, methylene blue (MB, safranin O (SF, toluidine blue (TB, and neutral red (NR, were successfully incorporated into a silica matrix by using ultrasound irradiation during the Stöber process. Several analyses were performed, including scanning dynamic light scattering (DLS, electron microscopy (SEM, nitrogen physisorption, FTIR spectroscopy, UV-vis, and diffuse reflectance spectroscopy. The entrapped dyes on silica were evaluated in singlet oxygen (1O2 generation under visible light irradiation, by means of the photosensitized oxidation of 9,10-dimethylanthracene (DMA. According to the results, the photocatalytic performance of the silica composites was improved, and the leakage of the dye from the particles was suppressed. Among these four different types of dye-doped silica composites, the SiO2-SF composite showed the most efficient delivery of 1O2.

    Lust, Merle; Muru, Karin

    2008-01-01

    This paper will provide a timeline overview of the of radiation protection infrastructure following the 1999 declaration of independence. In Estonia, an independent competent authority was inaugurated in 1996 and the first Radiation Act was approved by Parliament the following year, in 1997. This paper will address several important factors and the means which promoted development. International cooperation was and remains an essential factor worthy of discussion. For example participation in International Atomic Energy Agency technical co-operation programme and co-operation with neighbouring countries greatly facilitated greatly the development. Political choices and the long term goal of accession to the European Union had great importance to the process also. Today, the Republic of Estonia is member of European Union and has built up a well functioning radiation protection system according the international standards and requirements. This paper is intended to share the experience and to facilitate the learning process. (author)

  16. The tourism image of Estonia in Spain: a formulative approach

    2015-01-01

    Full Text Available We are living in an environment, where information flow is freer than ever. Nowadays everyone has access to global news and can make their own conclu-sions based on the perceived image. Therefore, the role of perception and image is becoming more important for different countries to attract visitors and in-vestors. Tourism is a way of selling the image of a country and the reputation and word of mouth generated from tourism activities are priceless to the image of a destination. This paper analyzes the case of Estonia, which is an emerging tourism market and quite new and unknown for Spain. The authors try to accent the importance of direct promotion, through a survey carried out to 341 Spanish people in Madrid. The result from this quantitative and formulative research method is that Estonia has to promote its tourism image better if the country wants to attract the Spanish tourist.

    2016-12-01

    Full Text Available This paper aims to contribute to a better understanding of the economic growth tendencies in Estonia and other formal post-socialist countries and the interaction between productivity growth and their determinants after the transition decades. So this paper is structured as follows. Firstly we will introduce an alternative growth accounting method to determine the components of productivity growth based on this concept. In Section we will also provide our empirical results in Estonia, Latvia, Lithuania and Hungary compared to the EU-15 countries between 1990 and 2011 how TFP (Total Factor Productivity, Physical and Labour Capital Accumulation can contribute to (increase or decrease economic performance of each country. Finally, we can conclude that the relationship between labour and output growth per capita has obviously and temporarily changed after the mid-1990s, which could be determined by the increasing role of such socio-economic factors as technological changes, capital accumulation and demographical fluctuations etc.

    1994-01-01

    Oil shale in Estonia will be competitive in the long term as a primary resource for power generating. The price of energy of Estonian oil shale is at present approximately 4 times lower than of coal. The price of electricity is anticipated to grow up to EEK 1.0/kWh in year 2020. The electricity price EEK 0.2/kWh at present in Estonia does not include capital costs needed for refurbishing of Estonian oil-shale-consuming power stations between the years 2000-2010. While all the prices and calculations of the enterprise are presented with no inflation adjustment, the other operation costs of oil shale retorting are anticipated for the prognosed period to remain at the present level: power consumption kWh 280/t crude oils and other operation costs (excluding labour, raw material and power consumption) EEK 100/t of oil

    2015-02-01

    A series of novel polyether derivatives of 9,10-anthraquinone (AQ) was synthesized and characterized by means of UV-Vis spectroscopy, acid-base titration and complexometric titration. The results were compared with 1-NEt2AQ and 1-NHEtAQ - model compounds of alkylaminoanthraquinones. Acetonitrile and methanol were used as solvents for determination of spectroscopic and acid-base properties. Complexometric titrations were carried out exclusively in acetonitrile. Spectral characteristic of these compounds strongly depends on pH. Addition of acid causes the decrease of absorption intensity and in some cases also a shift of the visible range band. The weakest base is the compound (2), and the strongest - compound (1), both in methanol and acetonitrile solution. The introduction of an additional substituent in the position 8 of the anthraquinone compound increases its basicity. The presence of metal ions causes changes in intensity of absorption (decrease for compounds (2) and (3) and increase with bathochromic shift for (1) and (4)). For the determination of the coordination properties aluminum (III) ions were chosen. The highest complex stability constant with Al (III) ions is observed for compound (1), and the weakest for compound (3). The elongation of the polyether chain decreases the stability of the complex formed.

  6. Strength behaviour of 10CrMo9.10 steel in nonsteady-state applications

    Seidel, C.

    2 testing runs with cyclic temperature increase were conducted on steel 10CrMo9.10 samples, i.e., at 500 degC and cyclic increase by 10, 25 and 50 degC, and at 550 degC and cyclic increase by 50 degC. Long-term strength was studied under a strain of 6.1 to 25.6 kp/mm 2 for 22,000 hours and the effect of periodical unloading was investigated on long-term strength at 550 degC. Sample loading and unloading proceeded within the range of 8.8 to 24.7 kp/mm 2 at an unloading rate of 8 to 100 %/min. Steel lifetime was not affected by the number of cycles. The effect of the changing load and of constant temperature without load on the long-term strength of the steel at 550 degC is shown graphically. The results showed a clear dependence of steel life on dwell time at the given temperature without load. (J.P.)

    Chlorinated polycyclic aromatic hydrocarbons (ClPAHs) have become a serious environmental concern due to their widespread occurrence and dioxin-like toxicities. In this work, the mechanism of the OH-initiated atmospheric oxidation degradation of 9,10-dichlorophenanthrene (9,10-Cl{sub 2}Phe) was investigated by using high-accuracy quantum chemistry calculations. The rate constants of the crucial elementary reactions were determined by the Rice–Ramsperger–Kassel–Marcus (RRKM) theory. The theoretical results were compared with the available experimental data. The main oxidation products are a group of ring-retaining and ring-opening compounds including chlorophenanthrols, 9,10-dichlorophenanthrene-3,4-dione, dialdehydes, chlorophenanthrenequinones, nitro-9,10-Cl{sub 2}Phe and epoxides et al. The overall rate constant of the OH addition reaction is 2.35 × 10{sup −12} cm{sup 3} molecule{sup −1} s{sup −1} at 298 K and 1 atm. The atmospheric lifetime of 9,10-Cl{sub 2}Phe determined by OH radicals is about 5.05 days. This study provides a comprehensive investigation of the OH-initiated oxidation degradation of 9,10-Cl{sub 2}Phe and should contribute to clarifying its atmospheric fate. - Highlights: • We studied a comprehensive mechanism of OH-initiated degradation of 9,10-Cl{sub 2}Phe. • The atmospheric lifetime of 9,10-Cl{sub 2}Phe determined by OH radical is about 5.05 d. • The rate constants of the crucial elementary steps were evaluated. • Water plays an important role in the formation of nitro-9,10-Cl{sub 2}Phe.

    Full Text Available Even Job's wife (Job 2:9-10, like the minor characters of the Hebrew Bible stories, does not play at all an insignificant role in the story of her husband, but she is however functional to better understand the author's design. In the traditional interpretation, based mostly on the Masoretic Text (MT, she was caught in a pattern that drew the negative opinion of the critics, perhaps the result of a misogynistic view, of Judeo-Hellenistic matrix, and then she appeared as hostile to Job, the righteous sufferer, for the aversion to the unconditional faithfulness of this man. Now, here we wanted to re-read this controversial figure, first of all starting from the received witnesses by both streams of the textual tradition, Jewish (MT and Greek (Old Greek = OG. In the first case, the words of his wife sound like an invitation to Job to curse Yahweh, responsible for his unjust suffering; in the second, however, they urge him to cry out to God his innocent suffering, even if he should be at the cost of being punished by death. So, two different portraits of woman - if not opposites - are derived from that, and her role in Job's story is defined negatively or positively, according to the archetype that is supposed.Tampoco la mujer de Job (Job 2,9-10, como sucede con otros personajes menores de las historias de la Biblia hebrea, juega un papel insignificante en la historia de su marido, sino que es relevante para entender mejor la intención del autor. En la interpretación tradicional, principalmente basada en el Texto Masorético (TM, ella estaba encuadrada dentro de un esquema que le atraía el juicio negativo de la crítica, fruto tal vez de una visión misógina de matriz judeo-helenística, y aparecía como hostil a Job, el justo sufridor, por la aversión a la fe incondicional de este. Ahora queremos revisar aquí esta controvertida figura, primero de todo a la luz de los testimonios de las dos ramas de la tradición textual hebrea (TM y griega

    The production and use of biogas, along with corresponding sector-specific activities and technologies, is a relatively new subject in Estonia. This paper gives an instructive overview of main barriers behind the development incentives, policy support and technological innovation in terms of emerging market for biogas. The article examines the complexity of market-related, political, technological and social obstacles for introduction biogas technologies. There is a major gap between resource potential, technological capacity and practice in Estonia. About 2 % of the theoretical potential of biogas is being used, totalling around 11 million Nm{sup 3}, based primarily on landfill biogas. First, political setting for biogas innovation is still vague, however, consolidated and enhanced since 2010 to compete with other renewables and mainstream energy technologies. The article underlines the statement that the reason why Estonian biogas production has not followed the path of growth and technology transfer is the low renewable electricity feed-in tariff. However, there are many other legal and engineering factors that have held back biogas applications and sector development in general. Stakeholders have established the Estonian Biogas Association, increasing sector's visibility, targeted lobby to support policy-making, technological and social innovation and professional networking. Though getting the biogas sector to succeed demands a comprehensive approach and involvement of more actors in demand side including local leaders and consumers, both enthusiasm and scepticism should be informed by a sound understanding of framework conditions and complexities for path-breaking transformations in energy systems. To promote biogas production, profitable and technologically feasible showcases should demonstrate benefits and issues to the target group and stakeholders. Instead agricultural and CHP development mode, the priority of using biogas in Estonia could be seen as

    We studied alcohol consumption and its consequences as a seasonal phenomenon in Estonia and analysed the social and environmental factors that may cause its seasonal rhythm. There are two important questions when researching the seasonality of human activities: (1) whether it is caused by natural or social factors, and (2) whether the impact of the factors is direct or indirect. Often the seasonality of social phenomena is caused by social factors, but the triggering mechanisms are related to environmental factors like temperature, precipitation, and radiation via the circannual calendar. The indicators of alcohol consumption in the current paper are grouped as: (1) pre-consumption phenomena, i.e. production, tax and excise, sales (beer, wine and vodka are analysed separately), and (2) post-consumption phenomena, i.e. alcohol-related crime and traffic accidents and the number of people detained in lockups and admitted to alcohol treatment clinics. In addition, seasonal variability in the amount of alcohol advertising has been studied, and a survey has been carried out among 87 students of Tartu University. The analysis shows that different phenomena related to alcohol have a clear seasonal rhythm in Estonia. The peak period of phenomena related to beer is in the summer, from June to August and the low point is during the first months of the year. Beer consumption correlates well with air temperature. The consumption of vodka increases sharply at the end of the year and in June; the production of vodka does not have a significant correlation with negative temperatures. The consumption of wine increases during summer and in December. The consequences of alcohol consumption, expressed as the rate of traffic accidents or the frequency of medical treatment, also show seasonal variability. Seasonal variability of alcohol consumption in Estonia is influenced by natural factors (temperature, humidity, etc.) and by social factors (celebrations, vacations, etc.). However

    Estonia is one of a few countries where the establishment of radiation protection and radioactive waste management infrastructure started only recently, soon after regaining independence in the beginning of 1990's. Both legislative and regulatory infrastructure had to be built from scratch, in parallel with the beginning of urgent activities and practices to manage waste streams inherited from the past. Despite significant deficiency of local expertise and specialists in the field, the main objectives of the establishment were set up: to enforce national legislation basing on contemporary international principles, criteria, requirements and to implement structures and procedures for an efficient regulation of radiation safety issues, including practices involving radioactive waste management and decommissioning

    At present Estonia has no operating nuclear or a radioactive material production facility. As a legacy of the past the country has become responsible for the decommissioning of two large nuclear cycle facilities of the former USSR. Besides limited funding, major problems arise from deficiencies in legislation, expertise, training and research. International co-operation has been of immense importance to overcome the problems, to establish the national radiation protection and radioactive waste management infrastructure and to launch decommissioning and remediation activities. An overview is given on the status and problems. Copyright (2000) Australasian Radiation Protection Society Inc

    Full Text Available Abstract Background Health impact assessments (HIA use information on exposure, baseline mortality/morbidity and exposure-response functions from epidemiological studies in order to quantify the health impacts of existing situations and/or alternative scenarios. The aim of this study was to improve HIA methods for air pollution studies in situations where exposures can be estimated using GIS with high spatial resolution and dispersion modeling approaches. Methods Tallinn was divided into 84 sections according to neighborhoods, with a total population of approx. 390 000 persons. Actual baseline rates for total mortality and hospitalization with cardiovascular and respiratory diagnosis were identified. The exposure to fine particles (PM2.5 from local emissions was defined as the modeled annual levels. The model validation and morbidity assessment were based on 2006 PM10 or PM2.5 levels at 3 monitoring stations. The exposure-response coefficients used were for total mortality 6.2% (95% CI 1.6–11% per 10 μg/m3 increase of annual mean PM2.5 concentration and for the assessment of respiratory and cardiovascular hospitalizations 1.14% (95% CI 0.62–1.67% and 0.73% (95% CI 0.47–0.93% per 10 μg/m3 increase of PM10. The direct costs related to morbidity were calculated according to hospital treatment expenses in 2005 and the cost of premature deaths using the concept of Value of Life Year (VOLY. Results The annual population-weighted-modeled exposure to locally emitted PM2.5 in Tallinn was 11.6 μg/m3. Our analysis showed that it corresponds to 296 (95% CI 76528 premature deaths resulting in 3859 (95% CI 10236636 Years of Life Lost (YLL per year. The average decrease in life-expectancy at birth per resident of Tallinn was estimated to be 0.64 (95% CI 0.17–1.10 years. While in the polluted city centre this may reach 1.17 years, in the least polluted neighborhoods it remains between 0.1 and 0.3 years. When dividing the YLL by the number of

    This article examines the association between alcohol excise tax rates and alcohol-related traffic accidents in Estonia. Monthly time series of traffic accidents involving drunken motor vehicle drivers from 1998 through 2013 were regressed on real average alcohol excise tax rates while controlling for changes in economic conditions and the traffic environment. Specifically, regression models with autoregressive integrated moving average (ARIMA) errors were estimated in order to deal with serial correlation in residuals. Counterfactual models were also estimated in order to check the robustness of the results, using the level of non-alcohol-related traffic accidents as a dependent variable. A statistically significant (P traffic accidents was disclosed under alternative model specifications. For instance, the regression model with ARIMA (0, 1, 1)(0, 1, 1) errors revealed that a 1-unit increase in the tax rate is associated with a 1.6% decrease in the level of accidents per 100,000 population involving drunk motor vehicle drivers. No similar association was found in the cases of counterfactual models for non-alcohol-related traffic accidents. This article indicates that the level of alcohol-related traffic accidents in Estonia has been affected by changes in real average alcohol excise taxes during the period 1998-2013. Therefore, in addition to other measures, the use of alcohol taxation is warranted as a policy instrument in tackling alcohol-related traffic accidents.

  6. The social costs of alcohol misuse in Estonia.

    2009-01-01

    The aim of this study was to estimate the social costs of alcohol misuse in Estonia in 2006. Using a prevalence-based cost-of-illness approach, both direct and indirect costs were considered, including tangible costs associated with health care, criminal justice, rescue services, damage to property, premature mortality, incarceration, incapability of working due to illnesses, and lower labor productivity. The results show that alcohol misuse cost Estonia more than EUR 200 million in 2006. The costs involved are estimated to represent 1.6% of the gross domestic product (GDP), which is relatively high in comparison with many other countries. In addition, the state receives less receipts from the alcohol excise tax than the costs that it incurs as a consequence of alcohol misuse, which points to the existence of economic inefficiency with respect to the alcohol market. The results of this study suggest that there is definitely a need for further cost-benefit analysis to reach a conclusion regarding the possible utility of government intervention. Copyright 2008 S.

    2002-01-01

    Radiocaesium contamination in soil was produced by two fallout's: a global fallout caused by nuclear weapons testing in the atmosphere (1950s to 1970s) and a regional one - during/after the Chernobyl accident (1986). The area] distribution of the 137 CS fallout after the 1986 accident was extremely uneven in Estonia. Our previous studies showed that about 60% of its total deposition with the countrywide mean of 2 kBq m -2 occurred predominantly in the north-eastern part of Estonia. In this region the maximum deposition approached the values of 40 kBq m -2 . This is the reason why soil profiles in this region have been of interest. We have also determined the 137 Cs activity concentrations as a function of soil depth during 1991-2000. Attempts have been made to model the found depth-distributions of radiocaesium concentration and to find the possible time-dependent behaviour of these distributions in soil. The migration of radiocaesium into soil is dependent on several factors: soil properties, vegetation, mode of deposition, etc. For this reason, averaged distribution parameters for both total and Chernobyl 137 Cs have been used for deriving general trends of the migration processes.

    Motor vehicle accidental injuries are a frequent cause of death among young children and adolescents. The goal of this study was to compare patterns of injury between three capitals (Budapest, Vilnius, and Tallinn). Information on 190 fatal traffic accidents (69 pedestrians, 14 bicyclists, and 107 motor vehicle occupants) between 2002 and 2006 was collected from databases of medico-legal autopsies. The role of victims in accidents, the location of injuries, cause of death, survival period, and blood alcohol levels were evaluated. One-hundred and forty-one (74%) victims had a passive role in traffic as pedestrians, passengers in cars, or public transport. In victims who died at the scene, the rate of head injury was higher than in cases who received medical treatment (odds ratio = 2.58, CI = 1.2-5.55, p = 0.0127). These results underline the importance of postmortem studies to examine the pathomechanism of fatal traffic accidental injuries and to provide information for the prevention of road traffic accidents against children and adolescents. © 2011 American Academy of Forensic Sciences.

    Full Text Available Temporal trends provide a good interpretation of change in stormwater quality over time. This study aimed to analyse trends and influences due to stormflow and baseflow. Grab samples of 18-19 years from 1995 to 2014 recorded at outlets of 7 Tallinn watersheds were analysed for monotonic trend through seasonal Mann Kendall test for long-term, short-term, baseflow and stormflow. Statistically significant downward trends (P-value (p 0.05 and < 0.2 for 3 – SS, 1 – BOD, 1 – TN and 1 – TP were identified. Statistically significant long-term upward trends of pH were revealed in 5 basins, which reduced to 2 with 5 less significant upward trends over the 10 year period, indicating improvements in pH reduction. Härjapea has the highest pH without trend but it includes an upward trend of TN at p = 0.051. The highly possible causes for downward trends are street sweeping, sewer network improvement, decline in sub-urban agricultural areas, etc. The upward trend results of pH are related to increased alkalinisation due to acidic rain, weathering of carbonate rocks, sewage discharge and alkaline road dust. In most of the basins, stormflow has more influence on trends than baseflow.

    Short chain chlorinated paraffins (SCCPs) are ubiquitously present as persistent organic pollutants in the environment. However, little information on the interaction of SCCPs with plants is currently available. In this work, young pumpkin plants (Cucurbita maxima × C. Moschata) were hydroponically exposed to the congener of chlorinated decane, 1,2,5,5,6,9,10-heptachlorodecane (1,2,5,5,6,9,10-HepCD), to investigate the uptake, translocation and transformation of chlorinated decanes in the intact plants. It was found that parent HepCD was taken up by the pumpkin roots, translocated from root to shoots, and phytovolatilized from pumpkin plants to air via the plant transpiration flux. Our data suggested that dechlorination of 1,2,5,5,6,9,10-HepCD to lower chlorinated decanes and rearrangement of chlorine atoms in the molecule were all mediated by the whole pumpkin seedlings. Chlorinated decanes were found in the shoots and roots of blank controls, indicating that chlorinated decanes in the air could be absorbed by leaves and translocated from shoots to roots. Lower chlorinated congeners (C 10 H 17 Cl 5 ) tended to detain in air compared to higher chlorinated congeners (C 10 H 16 Cl 6 and other C 10 H 15 Cl 7 ). Potential transformation pathway and behavior of 1,2,5,5,6,9,10-HepCD in pumpkin were proposed based on these experiments. Copyright © 2017 Elsevier Ltd. All rights reserved.

    Alison Marshall

    Full Text Available The IFN-γ-inducible chemokines CXCL9, CXCL10, and CXCL11 play a key role in many inflammatory conditions, particularly those mediated by T cells. Therefore, the production of these chemokines in peripheral tissues could be instrumental in the pathophysiology of tissue-specific immunological diseases such as oral lichen planus (OLP. In the present study, we assessed the production of keratinocyte-derived CXCL9/10/11 under basal and inflammatory conditions and investigated whether these chemokines were involved in the pathogenesis of OLP. We used semi-quantitative PCR, ELISA, chemotaxis assays, and fluorescence-activated cell sorting (FACS to assess the expression and functional role of CXCL9/10/11 in oral keratinocytes (three strains of normal human oral keratinocytes (NHOK, and the H357 oral cancer cell line in the presence or absence of IFN-γ. CXCL9/10/11 were also assessed in tissues from normal patients and those with oral lichen planus (OLP. The time course study in oral keratinocytes treated with IFN-γ showed that expression of CXCL9/10/11 chemokines was significantly enhanced by IFN-γ in a time-dependent manner. In particular, CXCL10, a prominent chemokine that was overexpressed by IFN-γ-stimulated NHOK, was able to effectively recruit CD4 lymphocytes, mainly CD4+CD45RA- cells. Significantly higher levels of CXCL9/10/11 were found in tissues from patients with OLP compared to normal oral mucosa. Taken together, the results demonstrate that normal oral keratinocytes produce chemotactic molecules that mediate T cell recruitment. This study furthers understanding of chemokine production in oral keratinocytes and their role in the pathophysiology of oral mucosa, with particular relevance to OLP.

    The basic idea of sustainable development is a firm understanding that all resources, renewable as well as non-renewable, are limited. Human activities should not exceed the buffering capacity of the earth's ecosystems and the replenishment potential of material cycles. Use of non-renewable, mainly mineral, resources should be kept at the minimum possible level, postponing the depletion of resources as far as possible. Concepts of environmental space and dematerialisation lie at the foundation of the practical launching of sustainable development. Analysis of regional sustainability and ecological efficiency of energy production, the balance of CO 2 , water, etc. were analysed for Estonia and Ida-Virumaa, north-eastern region of the country. The analysis carried out should be considered as a first step in the development and implementation of a national 'green' accounting system and environmental tax system based on the concept of environmental space.

Current environmental regulations exclude from the regulatory (control measures all the others except of well-argued prophylactic systems, built up on reliable prognoses. The last is inconceivable without the availability of a reliable, as well, and long-lasting retrospective time-series of L. seditiosum epidemics, which, as it is known from the last half of the XX century, are occupying large forest areas, usually not least than a half of (the small Estonia. An appropriate time-series would be useful, as well, for the more basic understanding of the accelerated mortality processes during the stand formation in early pole-age Scots pine plantations. Methodological principles of the use of NTM in an appropriate investigation together with the preliminary results of our research work, looking back for more than a century, are introduced and discussed in this investigation.

    The semiquinone radicals produced by one-electron reduction of 1-amino-4-hydroxy-9,10-anthraquinone and 1,4-diamino-9,10-anthraquinone have been studied in aqueous-organic mixed solvent using pulse radiolysis technique. Spectroscopic characteristics, kinetic characteristics of formation and decay, acid/base behaviour and redox characteristics of the semiquinones have been investigated and compared with those of some similar systems studied earlier. It has been shown that the variation of the disproportionation equilibria involving the reduced semiquinone radicals, the parent quinone and the fully reduced hydroquinone with pH of the solutions follow a similar trend as observed in the case of other dihydroxy quinones. Stability of the semiquinones over a broad pH range and their thermodynamic properties have been correlated. (Author)

    Two new phenanthrene and 9, 10-dihydrophenanthrene derivatives (1-2) with six known congeners (3-8) were isolated from the extraction of stems of Dendrobium officinale. Compounds 1 and 2 were based on carbon skeleton in which phenanthrene and 9, 10-dihydrophenanthrene moiety were linked with a phenylpropane unit through a dioxane bridge, respectively. Their structures were determined by comprehensive NMR spectroscopic data, the absolute configuration of new compounds were determined by comparing their experimental and calculated ECD for the first time. All the compounds were investigated contains two cancer cell lines (HI-60, THP-1). All the isolates showed cytotoxicity, especially compound 4 showed markedly cytotoxic activities against HI-60 and THP-1 cell lines with IC 50 values of 11.96 and 8.92 μM.

    Full Text Available During the years of imposed Soviet rule in Estonia from 1940 to its collapse in 1991, Estonian culture and the written word were subject to Soviet censorship which due to its perseverance, extent and rigidity constrained creativity and self-expression. At the same time, archival documents and memories testify that considerable shifting could take place within this censorship which on the surface appeared strict and regulated, depending on the general ideological stance and the officials and party functionaries in place at the time. Soviet censorship is usually studied and described with the activities of the censorship office Glavlit as the focal point. However, for a more complete overview, it would be wise to keep in mind that a whole row of other institutions and authorities with the Communist Party in front also were involved in censorship matters. When it came to censorship, it was the party that had the final word – as it did with everything else – and if needed, it also acted as punisher. Apart from the role of censor, the Communist Party, its departments (with the Department for Propaganda and Agitation or Ideology in front and its officials also took part in hands-on censorship work, both in terms of decision-making and in dealing with concrete incidents (breach of censorship rules and censor mistakes but also in the search for and pointing out of ideological flaws. One area in which the party’s censorship activities manifested itself in a rather vivid manner was the leadership and control of the Soviet press. When analysing materials from the bureau of the Communist Party of Estonia’s Central Committee, it becomes clear that the party’s governing organs were constantly active in this area. The manifestation of problems and discussion of flaws here point to the circumstance that journalists and editors did not accept the censorship rules, but rather tried to find possibilities and means through which to modify or ignore them

    research is more rooted in social, cultural and historical context than the American tradition. The former views linguistic biographies not as isolated narratives but as narratives situated in certain sociolinguistic and cultural situations. Thus, a linguistic biography can be a source for historical sociolinguistics when a researcher cannot obtain naturalistic spoken data any longer, and all evidence is therefore indirect. One can ask, to what extent are linguistic biographies unique? It is clear that a certain socio-cultural context produces certain (linguistic biographical templates, for instance, immigration and learning a new language or a possible feeling of dislocation and language learning anxiety. Thus, a comparison of linguistic biographies would be necessary in a longer perspective. Linguistic biographies research is a new field in Estonia. So far historians and scholars in literary history/theory have studied autobiographies. Dagmar Normet’s (1921-2008 memoirs, although not language learning memoirs per se, provide an intriguing view into a multilingual childhood of the 1920s-1930s. The narrator starts from the first childhood memories of studying German in addition to Estonian and Russian that she already knows, proceeds through the school years with occasional leaps into the future, the Soviet occupation, and ends at the moment of escape from Estonia in 1941 before the Nazi occupation. This memoir is unique because the author is probably the only Estonian writer of Jewish decent. Life in and with several languages in Tallinn appears to be something extremely natural and it seems there is no anxiety attached to this. Learning a new language or transfer to a school with a different language of instruction is described in detail, but without a feeling of detachment or dislocation. This presents extremely valuable information concerning the “linguistic climate” of the time, multilingualism in Tallinn, the dynamics of former Baltic German elite and the

    The structure and absolute stereoconfigurations of four adenosine adducts with (+/-)-7 alpha,8 beta-dihydroxy-9 beta, 10 beta-epoxy-7,8,9,10-tetrahydrobenzo(a)pyrene (BPDE) and their deoxyadenosine analogs have been determined. They result from both cis and trans addition of the N6 amino group of ademine to the 10 position of both enantiomers of BDPE. This was determined from studies of the nuclear magnetic resonance spectra, mass spectra, and circular dichroism spectra, as well as from their pKa values and chemical reactivities.

    In 9,10-anthraquinones the chemical shift of a peri-hydroxyl proton is affected by the substituents in the other benzenoid ring. These effects are additive. They are useful for the determination of substitution patterns and have been used to revise the structures of six previously reported...... anthraquinones containing methoxyl, hydroxyl, methylenedioxy and beta-methyl substituents. Because the chemical shifts of the other protons are hardly affected by substitutions in the other ring, the characteristic chemical shifts for a wide variety of substitution patterns could be derived....

    The aim of this study was to assess the reproducibility and validity of a non-quantitative 28-item food frequency questionnaire (FFQ). Children aged 9-10 years (n = 50) from three schools in Dunedin, New Zealand, completed the FFQ twice and a four-day estimated food diary (4DEFD) over a two-week period. Intraclass correlation coefficients (ICC) and Spearman's correlation coefficients (SCC) were used to determine reproducibility and validity of the FFQ, respectively. Weekly intakes were estimated for each food item and aggregated into 23 food items/groups. More than half of the food items/groups (52.2%) had an ICC ≥0.5. The median SCC between FFQ administrations was 0.66 (ranging from 0.40 for processed meat to 0.82 for sweets and non-dairy drinks). Cross-classification analysis between the first FFQ and 4DEFD for ranking participants into thirds showed that breakfast cereals had the highest agreement (54.0%) and pasta the lowest (34.0%). In validity analyses, 70% of food items/groups had a SCC ≥0.3. Results indicate that the FFQ is a useful tool for ranking children according to food items/groups intake. The low respondent burden and relative simplicity of the FFQ makes it suitable for use in large cohort studies of 9-10 year-old children in New Zealand.

    The semiquinone free radicals produced by one-electron reduction of 2-hydroxy-9-10-anthraquinone (2HAQ) and 2,6-dihydroxy-9,10-anthraquinone (26DHAQ) in aqueous formate solution, water-isopropyl alcohol-acetone mixed solvent and isopropyl alcohol have been studied using the pulse radiolysis technique. The absorption characteristics, kinetic parameters of formation and decay, acid-base behaviour and redox characteristics of the semiquinones have been investigated and compared with the corresponding characteristics of a few intramolecularly hydro-bonded anthrasemiquinone derivatives. The non-hydrogen-bonded semiquinones show two pKsub(a) values (4.7 and 10.7 for 2HAQ and 5.4 and 8.7 for 26DHAQ, respectively) within the pH range 1-14, whereas other intramolecularly hydrogen-bonded semiquinones show only one pKsub(a). The one-electron reduction potential (E' 7 ) values for 2HAQ (-440 mV) and 26DHAQ (- 400 mV) are more negative than those of the intramolecularly hydrogen-bonded systems. (Author)

    1974-01-01

    Work of the Tartusk radiocarbon laboratory for the last 15 years is presented. Methodological problems of the radiocarbon method are discussed. The geochemistry of carbon isotopes, principles of radiocarbon dating, and areas of its application are considered. Methods of recording natural radiocarbon and materials used for radiocarbon dating are discussed. Preliminary treatment of the samples and synthesis of the radioactive carbon carrier are presented. The preparation of the counter compound in the form of a liquid scintillator from the synthesized natural radiocarbon carrier is described. The scintillator efficiencies of different scintillators are compared. Data are given on the development of criteria for selecting the photoelectron multiplier. Construction of alumina cuvettes used for scintillation counting is described. It is noted that, in the counter apparatus system, amplitude analyzers with two differential discriminators are used, which allows directing the recording of activity to two 14 C regions. The results of using the radiocarbon method for different aspects of natural science and archeology are considered. Problems of geology of the late Pleistocene and the Pre-Baltic Holocene are considered: base of the mid-Valdaisk Karukyulask interglacier, history of deterioration of the final glacial mantle, development of a drainage system and late glacier, development and paleography of the Holocene, and others. New material on the chronology of primeval cultures in the Estonia region and on growth of meteoric craters are presented

  1. District heating rehabilitation project. Viljandi - Estonia. Final report

    1998-04-01

    The main objective of the project has been to assist Viljandi Municipality with the rehabilitation of their district heating system, and thereby to support the positive development of the district heating system in Viljandi to a more energy efficient and rational system and to achieve a significantly decrease in the pollution from the production of heat energy in Viljandi. The project has also included technical assistance to Viljandi DH company, in order to make them capable of operation and maintaining of the new substations, and also training of the local operational staff for operation of the complete district heating system. Viljandi is a county and is centrally located in Estonia, which makes Viljandi very suitable as recipient for a demonstration project. One important objective was the projects significantly positive environmental impact in reduction of the generated emissions of CO 2 , NO x and SO 2 , as the project includes installation of more efficient energy systems and supply of heat from the 2 existing district heating plants (both are partly fired with wood chips) instead of heating by very old and worn-out coal fired boilers and inexpedient designed substations with the present operational conditions.

  2. Women in Physics in Estonia: Many Duties, One Life

    2009-04-01

    In Estonia, women and men have equal legal rights. Women are expected to earn their living like men—and unlike men, to be the main (often the only) caregiver for the children. In the family women do most of the unpaid work, spending twice the amount of time on household duties as men. Laws about public preschool child care and child support obligations for noncustodial parents exist, but these laws are not always realized in practice. A generous policy of benefits for children under 1.5 years provides some relief for mothers. It is a challenge to balance a woman's traditional load of unpaid duties with the high demands of a science career. As in many other countries, with every step up the academic ladder the underrepresentation of women in science becomes more evident. Physics and engineering are perceived as male areas and women active in these areas are often treated as exceptions. Most obstacles met by women in science are difficult to recognize and neutralize because they are deeply informal. Activities for "gender and science" that exceed the limits of sociological study have no long tradition here and are yet finding their place in Estonian society.

  3. Partnership dynamics among migrants and their descendants in Estonia

    Full Text Available Background: Extensive scholarly literature documents the decline in marriage and increase in non-marital cohabitation and divorce across regions and countries of Europe, but we know less about the extent to which these new family behaviours that have emerged in host societies are adopted by migrants. Objective: The aim of this study is to examine partnership transitions among the migrants and their descendants in Estonia, who mainly originate from the European part of Russia. By investigating an East European context, the study contributes to a more comprehensive account of migrant populations in different socio-economic and cultural settings. Methods: The study is based on the Estonian Generations and Gender Survey (2004/2005 and the Estonian Family and Fertility Survey (1994/1997, and employs proportional hazards models. Results: The results show that new family formation patterns, associated with the Second Demographic Transition, are less prevalent among migrants. The difference between migrants and native Estonians is most pronounced in the mode of partnership formation and outcomes of cohabiting unions, whereas the results pertaining to union dissolution reveal a less systematic difference between population groups. Reflecting the relatively slow integration, the second-generation migrants exhibit partnership behaviour that differs from that of the native population. The observed differences between migrants and the native population appear largely similar for both men and women. Conclusions: The results lend support to socialisation, cultural maintenance, and adaptation hypotheses, and underscore the importance of contextual factors. The analysis reveals disruption effects of migration on partnership processes.

    2005-12-01

    Until recent years, waste oil and oil-contaminated waters commonly ended up in landfills. At some dump sites, ponds of oily liquids and leachate were formed. To remediate such ponds, an interdisciplinary approach is now required, keeping costs at an affordable level, particularly in countries with changing economies. From 1974 to 1993, liquid oily wastes taken to the Laguja landfill, in Estonia, were disposed of in a pond with a surface area of 9800 m2. It was estimated that the pond contained 4500-6000 m3 of oily water and 3500 m3 of oil-containing bottom sediments. This study aimed at developing an environmentally sound and cost-effective method for remediation of the oily liquids, leachate and contaminated underlying sediment material, to meet the existing legal demands. It was concluded that treatment of contaminated water is well established and the procedures carried out to meet the regulatory demands achieved satisfactory results. However, regarding treatment of sediments it was concluded that legal and technological aspects, as well as monitoring procedures are not fully established and are usually underestimated. Laboratory investigations can provide valuable information in decision-making, and contribute to effective full-scale remediation planning.

    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.

    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.

  8. Effectiveness of Environmental Impact Assessment system in Estonia

    International Nuclear Information System (INIS)

    Heinma, Kaupo; Poder, Tonis

    2010-01-01

    To be effective, an Environmental Impact Assessment (EIA) system, first, has to minimize the probability that projects with significant environmental effects are implemented without EIA, and second, minimize the number of EIAs, which do not provide decision makers with essential information, so that the decision is improved as a result of EIA. The objective of this study was to find out how frequently in Estonia the projects implemented without EIA have caused significant environmental effects, and to measure the relative frequency of EIAs that have no influence on decision. An extensive survey with e-mail distributed questionnaires was carried out to reveal information from governmental agencies, local self-governments, and developers. There was no evidence that projects authorized without EIA have had environmental impacts, which could have been mitigated as a result of EIA. In contrast, about half of EIAs did not alter the decision of relevant authorities. This proportion was valid to both mandatory EIAs and those initiated on judgement basis. In our view, the proportion of no-influence EIAs was excessive and indicated the need to reconsider the provisions applying to the projects with a mandatory EIA requirement as well as judgements practice.

    Full Text Available Several Telychian–Sheinwoodian strata exposed in Estonia are precisely dated using conodont biostratigraphy. The beds in the Valgu-1 section correspond to the uppermost Distomodus staurognathoides and Pterospathodus eopennatus ssp. n. 1 zones. In the Valgu-2 and Valgu-3 sections only the P. eopennatus ssp. n. 1 Zone is exposed. The strata in the Velise-Kõrgekalda section correspond to the Lower subzone of the P. amorphognathoides angulatus Zone. Marlstones in the Jädivere section are assigned to the P. a. lennarti Zone. In the Avaste section part of the P. a. lithuanicus Zone is exposed. On the Saastna Peninsula two stratigraphical intervals, the lower corresponding to the Upper subzone of the P. a. amorphognathoides Zone and the upper to the Upper Kockelella ranuliformis Zone, crop out along the shoreline. In Saastna the exposed strata are separated by a covered interval corresponding to five conodont zones, from the Lower Pseudooneotodus bicornis Zone to the Lower K. ranuliformis Zone.

    Full Text Available Job insecurity is a significant current social issue in many European countries. Slovakia and Estonia significantly differ in the prevalence of job insecurity. The main aim of the present study was to compare Slovakia and Estonia in regard to job insecurity by looking at socio-demographic, job and organisational predictors and individual and social consequences based on ESS round five data. The secondary aim was to examine relationships between job insecurity and its predictors as well as job insecurity and its consequences. The analysis covered employed people with unlimited or limited contracts, working 40-50 hours per week, within the age range of 20-60. The results suggested significant differences in the predictors of job insecurity for Slovakia and Estonia. However, the individual, social and economic consequences of job insecurity were similar for both countries. This study contributes to an enhanced understanding of job insecurity predictors and consequences in the European region.

    Large differences in prevalence of asthma have been reported between westernised countries and the former Eastern European countries, and still no consensus about the reasons for the differences exists. The aim of this study was to assess diagnostic labelling of obstructive airway diseases, comparing subjects with respiratory symptoms and the diagnoses obtained in Estonia, Finland, and Sweden. A postal questionnaire was sent to population-based random samples, and 44,483 (76%) answers were obtained from the 58,661 invited in 1996. Among men, current smoking was most common in Estonia, 60%, followed by Finland, 39%, and Sweden, 28%. In all three countries, 30% of women were current smokers. Most respiratory symptoms including wheezing were most common in Estonia, also among non-smokers. The prevalence of asthma was 2.0% and chronic bronchitis 10.7% in Estonia, while the opposite was found in Sweden with an asthma prevalence of 7.8% and a chronic bronchitis prevalence of 3.1%. The pattern in Finland was similar to that of Sweden. The same differences between the three countries were found also among young subjects. The total proportion of diagnosed obstructive lung diseases in subjects with respiratory symptoms was similar, but the diagnosis of asthma was considerably more common in Finland and Sweden. Chronic bronchitis was favoured in Estonia, also among young adults irrespectively of what symptoms were present. In a multivariate model with correction for confounders, the risk (OR) for having a diagnosis of asthma was 5.65 (95% CI: 4.86-6.56) when living in Sweden, and 3.51 (95% CI: 3.00-4.12) in Finland, whereas risk for chronic bronchitis was 0.28 (0.25-0.31) and 0.22 (0.19-0.25), respectively, compared to Estonia. The study indicates differences in diagnostic practices of obstructive lung diseases between the three countries

    A new derivative of hexaaza[1 6 ]paracyclophane in which p-phenylenes are alternately replaced by 9,10-anthrylenes was prepared to investigate the impact on overall π-conjugation as well as conformational change of the macrocycle. The charge and spin distribution for one-electron and three-electron oxidation of the macrocycle was elucidated by means of electrochemical, spectroelectrochemical, EPR spectroscopic, and SQUID magnetometric methods. In particular, the triradical trication was successfully isolated as an air-stable salt, and moreover, its structure was disclosed by X-ray analysis. The triradical trication was characterized as a spin-frustrated three-spin system with the antiferromagnetic exchange interaction (J/k B ≃ - 74 K).

    2010-01-01

    The Republic of Estonia is a small country in Northern Europe, with electrical energy production dependent mostly on oil shale. The local supply of oil shale has given Estonia its energetic independence but it also presents great challenges: it is waste-intensive and causes massive emission of greenhouse gases into the atmosphere. It also causes damage to the landscape and to the health of the population living near the mining and energy producing area. Due to the above mentioned problems the use of nuclear power has been taken into consideration, but the debate is at its beginning and the need for further analyses is great

    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

  1. Novel derivatives of 9,10-anthraquinone are selective algicides against the musty-odor cyanobacterium Oscillatoria perornata.

    Musty "off-flavor" in pond-cultured channel catfish (Ictalurus punctatus) costs the catfish production industry in the United States at least 30 million US dollars annually. The cyanobacterium Oscillatoria perornata (Skuja) is credited with being the major cause of musty off-flavor in farm-raised catfish in Mississippi. The herbicides diuron and copper sulfate, currently used by catfish producers as algicides to help mitigate musty off-flavor problems, have several drawbacks, including broad-spectrum toxicity towards the entire phytoplankton community that can lead to water quality deterioration and subsequent fish death. By use of microtiter plate bioassays, a novel group of compounds derived from the natural compound 9,10-anthraquinone have been found to be much more selectively toxic towards O. perornata than diuron and copper sulfate. In efficacy studies using limnocorrals placed in catfish production ponds, application rates of 0.3 micro M (125 micro g/liter) of the most promising anthraquinone derivative, 2-[methylamino-N-(1'-methylethyl)]-9,10-anthraquinone monophosphate (anthraquinone-59), dramatically reduced the abundance of O. perornata and levels of 2-methylisoborneol, the musty compound produced by O. perornata. The abundance of green algae and diatoms increased dramatically 2 days after application of a 0.3 micro M concentration of anthraquinone-59 to pond water within the limnocorrals. The half-life of anthraquinone-59 in pond water was determined to be 19 h, making it much less persistent than diuron. Anthraquinone-59 appears to be promising for use as a selective algicide in catfish aquaculture.

    The main deficiencies of the district heating system in Sillamae (Estonia) were identified as being inefficiency of the heat and power production plant, which has a very low capacity, lack of means for consumers to control their energy consumption due to the existing constant flow system, pollution from heat and power production based on oil shale, water and heat losses from the network and unclear agreements between the Silmet factory and Sillamae municipality. The available capital for funding is limited. It was investigated where in the system investments would have the greatest effect. A scenario where heat is supplied from individual gas-fired boilers was calculated. A financially viable scenario would be to change from cogeneration of heat and power (CHP) based on oil shale to either individual natural gas supply or peat-fueled heat production. The Sillamae municipality and the Estonian government should agree on a solution for Sillamae. There will be a cash flow problem if the project is implemented. This can be partly solved by introducing a longer loan period. it is expected that there will be no substantial changes in the consumers` heat demand in the `do nothing`scenario, and in other scenarios ca. 520 Tj/p.a. from the Solmet factory, 530 Tj/p.a. from the town and 260 Tj/p.a. as heat losses, totaling 1310 Tj/p.a..

    Full Text Available Noble crayfish Astacus astacus (L. is an indigenous and the only crayfish species in Estonia. It is potentially endangered by invasion of alien species, diseases and habitat deterioration but does not have legal protected status and is fished only for recreational purpose. Crayfish Working Group of Ministry of Environment and Department of Aquaculture of the Estonian University of Life Sciences have developed crayfish conservation and management plan. Since 1994 standardized test fishing with traps (which catch only crayfish over 7 cm TL has been carried out and database of these fishings shows, that crayfish is dwelling in more than 255 sites in the lakes, rivers, streams, artificial reservoirs. In 52% of monitored sites populations are weak, catch per trap night is below 1 specimen. Exceptionally rich is the stock on the island Saaremaa, where in 59% of populations catch per trap night is over 4 and can reach 50. Licensed recreational catch is allowed in regions, where monitoring data show good status of crayfish stock. It is not allowed to sell the crayfish caught on recreational license. Crayfishing season is limited with August, size limit in recreational fishery is 11 cm TL. There are 10 operating crayfish farms and 15 are under construction. The farms produce yearly around 1000 kg of commercial size crayfish for export to Finland. Over 200000 juveniles are produced for restocking yearly. Restocking projects e.g. restoration of populations, which have been lost because of plague have been successful. The main threat factor is crayfish plague. In 2006–2007 it destroyed the stock of crayfish farms of companies Veteko, Pähkla, Astacus and wild population of Põduste river on the island Saaremaa.

    Full text: The nuclear training facility at Paldiski was constructed in the early 1960's by the former USSR Navy. The hull sections of Delta and Echo class submarines each housing a full-sized ship reactor were installed in the main building of the site for training of navy personnel in safe operation of the submarine nuclear reactor systems. The first reactor was commissioned in 1968 and the second in 1982, while both was shut down in 1989. After Estonia's reproclamation of independence in 1991 the responsibility for the clean up and decommissioning of the Paldiski site became a subject of negotiations between Russia and Estonia. As the result Estonia took the ownership and control of the site in September 1995. Before the take over the Russian authorities defuelled the reactors and transported the spent fuel to Russia, dismantled the hull sections not related with reactor systems, seal-welded the hull sections housing the reactor vessels with their primary circuitry and enclosed those in reinforced concrete sarcophagi. The auxiliary facilities and radioactive waste were left intact. Main goals of the Conceptual Decommissioning Plan for the Paldiski facilities, developed under the auspices of the Paldiski International Expert Reference Group (Pier, a group established at the request of the Estonian government to advise local authorities to maintain the decommissioning and waste management at Paldiski) were defined as following: Establishing the waste management system and a long term monitored interim storage, corresponding to internationally accepted safety standards and capable to condition, receive and store all the waste generated during decommissioning of the facility; Reductions of the extent of radiologically controlled areas as much as possible, in order to minimise maintenance requirements. To achieve these goals the following main tasks were addressed in the short and medium term site management action plans: Rearrangement of site for the needs of

  19. Climatic trends in Estonia during the period of instrumental observations and climate scenarios

    International Nuclear Information System (INIS)

    Jaagus, J.

    1996-01-01

    Weather conditions in Estonia are quite variable. Long-term periodical fluctuations have been observed in meteorological values. At the same time, the climate change during the last 100-150 years is marked. As a general tendency, the climate has become more maritime. Air pressure is characterized by an increasing trend in spring and summer, and by a decreasing trend in autumn and winter. Mean air temperature has increased, particularly over the colder half of the year. Precipitation area totals have risen, most of all in autumn and winter. Snow cover duration has decreased significantly. General circulation model-based climate change scenarios expect a general increase in air temperature in Estonia with warming in winter more significant than that in summer. Moreover, they indicate an increase in precipitation, but the results of the individual models are quite variable. The transient scenario shows that the main increase in precipitation will not occur during next decades, but only at the end of the transient period, around 2070. It can be stated that observed tendencies of climate change in Estonia concur with expected changes caused by global warming. According to the long-term fluctuations of meteorological values in Estonia, changes different from general trends can take place during the next decade. An increase in mean air pressure, sunshine duration and snow cover duration, as well as a decrease in mean air temperature and precipitation is expected in the following years

    2016-04-19

    From 2020, the ownership of community pharmacies in Estonia will be limited to the pharmacy profession, and the vertical integration of wholesale companies and community pharmacies will not be allowed. The aim of this study was to evaluate the perception of different stakeholders in primary healthcare toward the new regulations of the community pharmacy sector in Estonia. A qualitative electronic survey was distributed to the main stakeholders in primary healthcare and higher education institutions providing pharmacy education ( n = 40) in May 2015. For data analysis, the systematic text condensation method was used. The study participants described two opposing positions regarding the development of community pharmacies in the future. Reform supporters emphasized increased professional independence and more healthcare-oriented operation of community pharmacies. Reform opponents argued against these ideas as community pharmacists do not have sufficient practical experience and finances to ensure sustainable development of the community pharmacy sector in Estonia. Based on the current perception of all respondents, the future operation of the community pharmacy sector in Estonia is unclear and there is urgent need for implementation criteria for the new regulations.

  2. The recertification of the professional accounting qualification in Estonia: the requirements and quality of CPD

    Full Text Available The recertification of the professional accounting qualification in Estonia: the requirements and quality of CPD As the purpose of a professional qualification should be to ensure quality to employers/customers, appro-priate requirements for professional training should not be too low. On the other hand, too high require-ments for the amount of training would lead to the situation where maintaining the level is expensive and if the labour market does not consider having a professional certificate necessary, recertification will be discarded. The purpose of the research was to identify the factors that influence an accountant’s decision whether to recertify his/her professional qualification or not. The conditions of recertification were ana-lysed and compared to other countries as were the requirements set up for auditors. The results of the survey revealed that in Estonia the decision not to recertify one’s professional qualification was mainly due to not having fulfilled the required number of qualification hours or not having certificates proving one’s participation in qualification training sessions. At the same time, compared to other countries, the requirements in Estonia are very low. So that the increase in the amount of training would not hinder recertification, alternative solutions for Estonia are proposed in the article.

    In comparison with neighbouring Scandinavian countries, the use of digoxin in Estonia is high. The present study was carried out to determine the use pattern of digoxin in Estonia and bioavailability of the local market leader preparation in comparison with Lanoxin. Drug use data were evaluated from the annual reports of wholesale companies. For the bioequivalence study, a single-blind cross-over randomised two-way single-dose comparative bioavailability study was performed using 14 healthy volunteers. Digoxin concentrations in serum samples and urine were measured by chemiluminescent competitive immunoassay. The use of digoxin in Estonia has increased by 35% during the period 1994-97. The steady market leader was the local generic drug. No statistically significant differences were found in any pharmacokinetic parameter between the generic preparation and Lanoxin. All parameters showed considerable variability. The total amount of drug excreted was the parameter with lowest inter- individual variation. The present study indicates that the generic digoxin preparation studied is bioequivalent to Lanoxin. The increasing use of digoxin in Estonia is not caused by low bioavailability of the local market leader but by therapeutic traditions.

    The infrared multiple-photon dissociation (IRMPD) spectra of protonated acenaphthene ([ACN+H] + ) and 9,10-dihydrophenanthrene ([DHP+H] + ) have been recorded using an infrared free electron laser after the compounds were protonated by electrospray ionization and trapped in a Fourier transform ion cyclotron mass spectrometer. In both compounds, the loss of two mass units is predominant. Density functional calculations (B3LYP/6-311++G(d,p)) of the infrared spectra of all possible protonated isomers of each species showed that the observed IRMPD spectra are best fit to the isomer with the largest proton affinity and lowest relative electronic energy. Potential energy surfaces of the most stable isomers of [ACN+H] + and [DHP+H] + have been calculated for H and H 2 loss. The lowest energy barriers are for loss of H 2 , with predicted energies 4.28 and 4.15 eV, respectively. After H 2 ejection, the adjacent aliphatic hydrogens migrate to the bare ejection site and stabilize the remaining fragment. Single H loss may occur from [ACN+H] + but the energy required is higher. No single H loss is predicted from [DHP+H] + , only H migration around the carbon skeleton. The vibrational bands in the parent closed-shell protonated polycyclic aromatic hydrocarbons are compared to bands observed from the interstellar medium.

    The 3, 4, 9, 10-perylenetetracarboxylic dianhydride (PTCDA) doped polymer films were prepared with Polypyrrole (PPy) and Polyvinyl alcohol (PVA) polymers by solution-casting. The change in structure and chemical composition of samples was identified by XRD and FTIR respectively. The UV-visible spectroscopy demonstrates the optical characteristics and band gap properties of sample. The homogeneous morphology of sample for higher wt% of PTCDA was examined by atomic force microscopy (AFM). The differential scanning calorimetry (DSC) results demonstrate the decrease in melting temperature (Tm) and degree of crystallinity (χc%) of polymeric organic semiconductor. The mechanical property demonstrates the high tensile strength and improved plasticity nature. Impedance spectroscopy was evaluated to determine the conductivity response of polymeric organic semiconductor. The highest DC conductivity (2.08×10-3 S/m) was obtained for 10 wt% of PTCDA at 140 °C. The decrease in activation energy (Ea) represents the non-Debye process and was evaluated from the slope of ln σdc vs. 103/T plot.

    Molecular solar thermal storage (MOST) systems have been largely limited to three classes of molecular motifs: azo-benzene, norbornadiene, and transition metal based fulvalene-tetracarbonyl systems. Photodimerization of anthracene has been known for a century; however, this photoprocess has not been successfully exploited for MOST purposes due to its poor energy storage. Using well-calibrated theoretical methods on a series of [n.n](9,10)bis-anthracene cyclophanes, we have exposed that they can store solar energy into chemical bonds and can release in the form of heat energy on demand under mild conditions. The storage is mainly attributed to the strain in the rings formed by the alkyl linkers upon photoexcitation. Our results demonstrate that the gravimetric energy storage density for longer alkyl-chain linkers (n > 3) are comparable to those for the best-known candidates; however, it lacks some of the deleterious attributes of known systems, thus making the proposed molecules desirable targets for MOST applications.

    9,10-Phenanthrenequinone monoxime has been used as a reagent for the spectrophotometric determination of ruthenium(III) and rhodium(III) after extraction into molten naphthalene. The extracted mixture of the metal complex and naphthalene was dissolved in chloroform and ruthenium and rhodium were determined spectrophotometrically. Beer's law holds in the concentration range of 0.2-4.1 μg/cm 3 for ruthenium and 0.3-5.3 μg/cm 3 for rhodium in 10 cm 3 of the final solution. The molar absorptivities and Sandell sensitivities are calculated to be 9.70 x 10 3 l mol -1 cm -1 and 0.01 μg/cmsup(2 ) (660 nm) for ruthenium and 1.13 x 10 4 l mol -1 cm -1 and 0.009 μg/cm 2 (410 nm) for rhodium respectively. Aliquots containing 2.0 μg of ruthenium and 4.1 μg of rhodium give mean absorbances of 0.192 and 0.451 with standard deviations of 0.0017 and 0.0039, respectively. Interference of various ions has been studied and the method has been applied to the determination of ruthenium and rhodium in various synthetic mixtures. This procedure is also applied to the simultaneous determination of ruthenium and rhodium present together in a solution. (author)

    Silver nanoparticles (Ag NPs) were prepared by solution combustion method with urea as fuel. Silver nanoparticles were characterized by UV-visible spectroscopy, X-ray diffraction (XRD) and scanning electron microscopy (SEM) techniques. Surface-enhanced Raman scattering (SERS) of 2-bromo-3-methyl-1,4-dimethoxy-9,10-anthraquinone (BMDMAQ) adsorbed on silver nanoparticles was investigated. The orientation of BMDMAQ on silver nanoparticles was inferred from nRs and SERS spectral features. Density functional theory (DFT) calculation was also performed to study the theoretical performance. The observed spectral features such as the high intensity of C-H out-of-plane bending mode and ring C-C stretching mode revealed that BMDMAQ adsorbed on silver surface through 'stand-on' orientation. Anthraquinone (AQ) derivatives have wide biomedical application which includes laxatives, antimalarials and antineoplastics used in the treatment of cancer. This present study would help to identify the interaction of drug molecules with DNA. Copyright © 2015 Elsevier B.V. All rights reserved.

  18. 9,10-Anthraquinone hinders β-aggregation: How does a small molecule interfere with Aβ-peptide amyloid fibrillation?

    Amyloid aggregation is linked to a number of neurodegenerative syndromes, the most prevalent one being Alzheimer's disease. In this pathology, the β-amyloid peptides (Aβ) aggregate into oligomers, protofibrils, and fibrils and eventually into plaques, which constitute the characteristic hallmark of Alzheimer's disease. Several low-molecular-weight compounds able to impair the Aβ aggregation process have been recently discovered; yet, a detailed description of their interactions with oligomers and fibrils is hitherto missing. Here, molecular dynamics simulations are used to investigate the influence of two relatively similar tricyclic, planar compounds, that is, 9, 10-anthraquinone (AQ) and anthracene (AC), on the early phase of the aggregation of the Aβ heptapeptide segment H14QKLVFF20, the hydrophobic stretch that promotes the Aβ self-assembly. The simulations show that AQ interferes with β-sheet formation more than AC. In particular, AQ intercalates into the β-sheet because polar interactions between the compound and the peptide backbone destabilize the interstrand hydrogen bonds, thereby favoring disorder. The thioflavin T-binding assay indicates that AQ, but not AC, sensibly reduces the amount of aggregated Aβ1–40 peptide. Taken together, the in silico and in vitro results provide evidence that structural perturbations by AQ can remarkably affect ordered oligomerization. Moreover, the simulations shed light at the atomic level on the interactions between AQ and Aβ oligomers, providing useful insights for the design of small-molecule inhibitors of aggregation with therapeutic potential in Alzheimer's disease.

    Full Text Available Thin films of nanocrystalline 3,4,9,10-perylene-tetracarboxylic-diimide (PTCDI were prepared on quartz substrates by thermal evaporation technique. The structural properties were identified by transmission electron microscopy (TEM and the X-ray diffraction (XRD. The optical properties for the films were investigated using spectrophotometric measurements of the transmittance and reflectance at normal incidence of light in the wavelength range from 200 to 2500 nm. The optical constants (refractive index n and absorption index k were calculated and found to be independent on the film thickness in the measured film thickness range 117–163 nm. The dispersion energy (Ed, the oscillator energy (Eo, and the high-frequency dielectric constant ε∞ were obtained. The energy band model was applied, and the types of the optical transitions responsible for optical absorption were found to be indirect allowed transition. The onset and optical energy gaps were calculated, and the obtained results were also discussed.

    9,10-Anthraquinone (AQ) was a new contaminant, with unknown sources, occurred globally in tea. European Union (EU) fixed the maximum residue limit (MRL) of 0.02mg/kg. The pollution source of AQ in tea was traced from the view of AQ deposit on tea crop by simulation. The possible contamination pathway and main factors to decrease AQ were explored in tea cultivation- tea manufacture- tea infusion, on the basis of AQ analytical methods by using solvent extraction and gas chromatography-tandem mass spectrometry (GC-MS/MS) quantification. 58.8-84.6% of AQ degraded in tea processing, and drying played a key role to reduce the AQ contamination. Certain concentration of AQ deposited on tea shoots could resulted in AQ beyond the MRL of 0.02mg/kg in tea. AQ leaching into tea brew (about 10%) could lead to the possible health risk. AQ deposit on tea crop during the tea cultivation might cause the AQ contamination in tea. Copyright © 2017. Published by Elsevier Ltd.

    Inhalation of 9,10-phenanthrenequinone (9,10-PQ), a major quinone in diesel exhaust, exerts fatal damage against a variety of cells involved in respiratory function. Here, we show that treatment with high concentrations of 9,10-PQ evokes apoptosis of lung cancer A549 cells through production of reactive oxygen species (ROS). In contrast, 9,10-PQ at its concentrations of 2 and 5 μM elevated the potentials for proliferation, invasion, metastasis and tumorigenesis, all of which were almost completely inhibited by addition of an antioxidant N-acetyl-L-cysteine, inferring a crucial role of ROS in the overgrowth and malignant progression of lung cancer cells. Comparison of mRNA expression levels of six aldo-keto reductases (AKRs) in the 9,10-PQ-treated cells advocated up-regulation of AKR1B10 as a major cause contributing to the lung cancer malignancy. In support of this, the elevation of invasive, metastatic and tumorigenic activities in the 9,10-PQ-treated cells was significantly abolished by the addition of a selective AKR1B10 inhibitor oleanolic acid. Intriguingly, zymographic and real-time PCR analyses revealed remarkable increases in secretion and expression, respectively, of matrix metalloproteinase 2 during the 9,10-PQ treatment, and suggested that the AKR1B10 up-regulation and resultant activation of mitogen-activated protein kinase cascade are predominant mechanisms underlying the metalloproteinase induction. In addition, HPLC analysis and cytochrome c reduction assay in in vitro 9,10-PQ reduction by AKR1B10 demonstrated that the enzyme catalyzes redox-cycling of this quinone, by which ROS are produced. Collectively, these results suggest that AKR1B10 is a key regulator involved in overgrowth and malignant progression of the lung cancer cells through ROS production due to 9,10-PQ redox-cycling. - Highlights: • 9,10-PQ promotes invasion, metastasis and tumorigenicity in lung cancer cells. • The 9,10-PQ-elicited promotion is possibly due to AKR1B10 up

    2006-01-01

    The history of oil shale mining in Estonia has reached its century mark. Three oil shale branches have been formed and have been working on the basis of Estonian oil shale deposits: the mining industry (underground and surface extraction), the power industry (heat and electric energy generation), and the chemical industry (gas and synthetic oils). The authors attempted to summarize the experience of the activities of these branches and to make into a whole the results of their research developments in the past years, as well as to form a notion about perspectives of oil shale in Estonia. Variants of the mining-chemical oil shale complex production and trade patterns differed from used ones. Mining methods, thermal processing of oil shale, and solid, liquid, and gas waste recovery have been studied, analyzed, and worked out up to the present. Setting up a flexible trade structure within the framework of that complex is considered the main economic mechanism capable of balancing production costs of such a complex with its earnings, which could respond properly to any, even peak, fluctuations of the market for final products processed from oil shale. Data of the working 'Estonia' oil shale mine were used as the basis of the analysis and practical conclusions. Information on the mine being projected in the region of Ojamaa in the northeast of Estonia was taken as the data of the worthwhile supplier. Oil shale processing chemical complex is considered in two structural alternatives: in technological chain with the 'Estonia' mine (the first variant), and the projected mine of a new technical level (the second variant).

    Full Text Available Pharmacists have an important role in detecting, preventing, and solving prescription problems, which if left unresolved, may pose a risk of harming the patient.Objective: The objectives of this study were to evaluate the feasibility of a generic study instrument for documentation of prescription problems requiring contact with prescriber before dispensing. The study was organized: 1 by countries: Estonia, Norway and Sweden; 2 by type of prescriptions: handwritten prescriptions, printouts of prescriptions in the electronic medical record and electronically transmitted prescriptions to pharmacies; and 3 by recording method - self-completion by pharmacists and independent observers.Methods: Observational study with independent observers at community pharmacies in Estonia (n=4 and Sweden (n=7 and self-completed protocols in Norway (n=9.Results: Pharmacists’ in Estonia contacted the prescriber for 1.47% of the prescriptions, about 3 times as often as in Norway (0.45% and Sweden (0.38%. Handwritten prescriptions dominated among the problem prescriptions in Estonia (73.2%, printouts of prescriptions in the electronic medical record (89.1% in Norway and electronically transmitted prescriptions to pharmacies (55.9% in Sweden.More administrative errors were identified on handwritten prescriptions and printouts of prescriptions in the electronic medical record in Estonia and in Norway compared with electronically transmitted prescriptions to pharmacies in Sweden (p<0.05 for prescription types and p<0.01 for countries. However, clinically important errors and delivery problems appeared equally often on the different types of prescriptions. In all three countries, only few cases of drug interactions and adverse drug reactions were identified.Conclusion: Despite the different patterns of prescription problems in three countries, the instrument was feasible and can be regarded appropriate to document and classify prescription problems necessitating contact

  5. Chameleonic reactivity of vicinal diazonium salt of acetylenyl-9,10-anthraquinones: synthetic application toward two heterocyclic targets.

    The nature of products in the diazotization of 1-amino-2-acetylenyl-9,10-anthraquinones strongly depends on the nature of substituents at both the alkyne and at the anthraquinone core. Donor substitution (NHAr, OH) at the fourth position stabilizes the diazonium salt at C1, decelerating electrophilic cyclization at the arylethynyl substituent at C2. This effect allows the replacement of the diazonium with azide group and subsequent closure into isoxazole ring with preservation of the alkyne. In contrast, electrophilic 5-exo-dig cyclizations to condensed pyrazoles is observed for the combination of donor substituents at the aryl alkyne moiety and an OAc substituent at C4. The latter process provides a new synthetic route to 3-ethynyl-[1,9-cd]isoxazol-6-ones that are difficult to access otherwise. DFT calculations suggest that donor substituents have only a minor effect on alkyne and diazonium polarization in the reactant but provide specific transition state stabilization by stabilizing the incipient vinyl cation. This analysis provides the first computational data on electrophilic 5-exo-dig cyclization in its parent form and the nucleophile-promoted version. This cyclization is a relatively fast but endothermic process that is rendered thermodynamically feasible by the enol-keto tautomerization with concomitant aromatization in the five-membered heteroaromatic ring. Computations suggest that the importance of nucleophilic assistance in the transition state for a relatively weak nucleophile such as water is minor because the energy gain due to the Lewis base coordination to the carbocationic center is more than compensated for by the unfavorable entropic term for the bimolecular proces.

Previous studies have stated that the hydrophobic effect controls PAH sorption, but no study has been conducted to quantify the exact contribution of the hydrophobic effect. Considering the well-defined structure of carbon nanotubes and their stable chemical composition in organic solvents, three multi-walled carbon nanotubes (MWCNTs) were selected as a model adsorbent. Phenanthrene (PHE) and its degradation intermediates 9-phenanthrol (PTR) and 9, 10-phenanthrenequinone (PQN) were used as model adsorbates. To quantify the contribution of the hydrophobic effect for these three chemicals, the effect of organic solvent (methanol and hexadecane) was investigated. Adsorption isotherms for PHE, PTR and PQN were well fitted by the Freundlich isotherm model. A positive relationship between adsorption affinities of these three chemicals and specific surface area (SSA) was observed in hexadecane but not in water or methanol. Other factors should be included other than SSA. Adsorption of PQN on MWCNTs with oxygen functional groups was higher than that on pristine MWCNTs due to π-π EDA interactions. The contribution of hydrophobic effect was 50%-85% for PHE, suggesting that hydrophobic effect was the predominant mechanism. This contribution was lower than 30% for PTR/PQN on functionalized MWCNTs. Hydrogen bonds control the adsorption of PTR, and π-π bonding interactions control PQN sorption after screening out the hydrophobic effect in hexadecane. Hydrophobic effect is the control mechanism for nonpolar chemicals, while functional groups of CNTs and solvent types control the adsorption of polar compounds. Extended work on quantifying the relationship between chemical structure and the contribution of the hydrophobic effect will provide a useful technique for PAH fate modeling.

    The U.S. Geological Survey (USGS), as part of the National Assessment of Coastal Change Hazards project, conducts baseline and storm-response photography missions to document and understand the changes in vulnerability of the Nation's coasts to extreme storms (Morgan, 2009). On September 9-10, 2008, the USGS conducted an oblique aerial photographic survey from Calcasieu Lake, Louisiana, to Brownsville, Texas, aboard a Cessna C-210 (aircraft) at an altitude of 500 feet (ft) and approximately 1,000 ft offshore. This mission was flown to collect baseline data for assessing incremental changes of the beach and nearshore area, and the data can be used in the assessment of future coastal change.The photographs provided in this report are Joint Photographic Experts Group (JPEG) images. ExifTool was used to add the following to the header of each photo: time of collection, Global Positioning System (GPS) latitude, GPS longitude, keywords, credit, artist (photographer), caption, copyright, and contact information. The photograph locations are an estimate of the position of the aircraft at the time the photograph was taken and do not indicate the location of any feature in the images (see the Navigation Data page). These photographs document the state of the barrier islands and other coastal features at the time of the survey. Pages containing thumbnail images of the photographs, referred to as contact sheets, were created in 5-minute segments of flight time. These segments can be found on the Photos and Maps page. Photographs can be opened directly with any JPEG-compatible image viewer by clicking on a thumbnail on the contact sheet.In addition to the photographs, a Google Earth Keyhole Markup Language (KML) file is provided and can be used to view the images by clicking on the marker and then clicking on either the thumbnail or the link above the thumbnail. The KML file was created using the photographic navigation files. The KML file can be found in the kml folder.

    On four casts of steel 8 CrMoNiNb 9 10 with about 0.06% C, 0.25; Si, 0.7% Mn, 0.012% N, 0.002 to 0.020% Al, 2.25% Cr, 0.94% Mo, 0.63 to 0.91% Nb and 0.67% Ni, transformation behaviour and structural changes during long-time annealing at 500 to 750 degC lasting up to 30,000 h were studied in unformed condition and after previous cold forming. The carbon content was largely bound in form of primary niobium carbonitrides so that during quenching and tempering low-carbon bainite was formed, or at very slow cooling a ferritic structure without pearlite. Martensite occurred only after fast cooling from temperatures above 1200 degC. Bainite exhibited a very high dislocation density and a large number of coherent niobium carbonitrides. During tempering, the precipitates overaged, and the dislocations started to arrange themselves to subgrain boundaries. Hardness and strength in quenched and tempered condition were essentially governed by dislocation density and size of subgrains. In the whole range of bainite transformation, they are only slightly dependent upon the cooling rate and hence upon the dimensions of the products. The structural changes which occurred in bainitic material during long-time aging and led to a ferritic structure in the final state were interpreted as recovery and recrystallization. In unformed and slightly formed material recrystallization led to a very coarse-grained structure. In highly formed material a very fine-grained structure was achieved by recrystallization. By a high degree of cold forming the recrystallization process was considerably promoted. With an annealing time of 10 5 h, no recrystallization is to be expected for unformed specimens of the studied cast up to 580 degC, but above 650 degC complete recrystallization. (author)

    Directory of Open Access Journals (Sweden)

    Rein Veidemann

    2012-04-01

    Full Text Available This focus of this article is the fate of the cultural narrative that has most influenced Estonian culture of the 20th century – Young Estonia. The point of departure for the analysis is Tiit Hennoste’s 2005 essay ”Young Estonia – An Unfinished Project for Self-Colonization”, which I interpret as the interruption of Young Estonia’s ”great narrative”. Hennoste’s demythologizing approach should be regarded in the context of postmodernism (or of postcolonial treatments of literature and art. I argue that the fact that Young Estonia’s models for cultural movements were located in Europe did not automatically lead to the assimilation of 20th century Estonia (literary culture. Neither did they engage in an automatic copying of European culture; their activities might better be regarded as a process of intertexual enrichment. In what follows, the fate of the narrative of Young Estonia will be traced both in terms of the literary field of Soviet Estonia in the 1950s and 1960s, and in exile. I claim that renewed awareness of the narrative of Young Estonia can be traced to the publication of a collection of Gustav Suits’ Poems in 1959, edited and with an afterword by Endel Sõgel. If one lowers the volume on the vulgar Soviet ideologization in Sõgel’s text, key words that characterize the Young Estonia canon remain in place undisturbed: innovativeness, intellectual greatness, turning point, the social nature of art and literature, consonance of the aesthetic and the ethical. Sõgel’s framing of Young Estonia stands in contrast to its apologetic treatment in the postwar Estonian diaspora. On the one hand, this line of interpretation follows the basic outlines of a critical narrative that developed in the 1920s; on the other, since most of Young Estonia’s authors and followers among the Estonian literary elite had gone into exile in 1944, diaspora interpretations represent a definite literary-political position. In the 1960s a

    To examine the association between diet and physical activity and sedentary behaviours in 9-10-year-old children. A cross-sectional study using data from the SPEEDY (Sport, Physical activity and Eating behaviour: Environmental Determinants in Young People) study undertaken in Norfolk, UK. Data from 4-day food diaries and 7 days of accelerometery were matched on concurrent days. Time spent in moderate-to-vigorous physical activity (MVPA), time spent in sedentary behaviour and various measures of dietary intake were collected. Covariates included age, sex, weight status, family socio-economic status, and energy intake reporting quality. Multivariable regression models, adjusted for clustering of children by school and stratified by sex, were fitted to examine the associations between dietary measures and physical activity and sedentary outcomes. In total, 1317 children (584 boys and 733 girls) provided concurrent data. Boys in the highest quartile of energy percentage from protein spent approximately 6 min [95% confidence interval (CI) 0-12] less in MVPA compared with boys in the lowest quartile. Those in the highest quartiles of fruit and vegetable intake and fruit juice intake had respective average activity counts per minute that were 56 above (95% CI 8-105) and 48 below (95% CI 2-95) those in the lowest quartiles, whilst those in the highest quartile of fizzy drink consumption spent approximately 7 min (95% CI 2-13) more in MVPA and approximately 14 min (95% CI 5-24 min) less in sedentary behaviour. Boys in the highest quartile of savoury snack consumption spent approximately 8 min (95% CI 2-13 min) more in MVPA per day, and approximately 12 min (95% CI 2-23) less in sedentary behaviour. No significant associations were apparent among girls. Few associations were detected, and the directions of those that were apparent were mainly counterintuitive. The extent to which this reflects a true lack of association or is associated with the measurement methods used for

    Little is known about ethnic, cultural and socioeconomic differences in childhood ownership and attitudes to pets. The objective of this study was to describe the factors associated with living with different pet types, as well as factors that may influence the intensity of relationship or 'attachment' that children have to their pet. Data were collected using a survey of 1021 9-10 year old primary school children in a deprived area of the city of Liverpool, UK. Dogs were the most common pet owned, most common 'favourite' pet, and species most attached to. Twenty-seven percent of dog-owning children (10% of all children surveyed) reported living with a 'Bull Breed' dog (which includes Pit Bulls and Staffordshire Bull Terriers), and the most popular dog breed owned was the Staffordshire Bull Terrier. Multivariable regression modelling identified a number of variables associated with ownership of different pets and the strength of attachment to the child's favourite pet. Girls were more likely to own most pet types, but were no more or less attached to their favourite pet than boys. Children of white ethnicity were more likely to own dogs, rodents and 'other' pets but were no more or less attached to their pets than children of non-white ethnicity. Single and youngest children were no more or less likely to own pets than those with younger brothers and sisters, but they showed greater attachment to their pets. Children that owned dogs lived in more deprived areas than those without dogs, and deprivation increased with number of dogs owned. 'Pit Bull or cross' and 'Bull Breed' dogs were more likely to be found in more deprived areas than other dog types. Non-whites were also more likely to report owning a 'Pit Bull or cross' than Whites. Gender, ethnicity and socioeconomic status were associated with pet ownership, and sibling status with level of attachment to the pet. These are important to consider when conducting research into the health benefits and risks of the

    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.

  2. Dual effects of N-acetyl-L-cysteine dependent on NQO1 activity: Suppressive or promotive of 9,10-phenanthrenequinone-induced toxicity

    A typical antioxidant, N-acetyl-L-cysteine (NAC) generally protects cells from oxidative damage induced by reactive oxygen species (ROS). 9,10-Phenanthrenequinone (9,10-PQ), a major quinone in diesel exhaust particles, produces ROS in redox cycling following two-electron reduction by NAD(P)H:quinone oxidoreductase 1 (NQO1), which has been considered as a cause of its cyto- and genotoxicity. In this study, we show that NAC unexpectedly augments the toxicity of 9,10-PQ in cells with low NQO1 activity. In four human skin cell lines, the expression and the activity of NQO1 were lower than in human adenocarcinoma cell lines, A549 and MCF7. In the skin cells, the cytotoxicity of 9,10-PQ was significantly enhanced by addition of NAC. The formation of DNA double strand breaks accompanying phosphorylation of histone H2AX, was also remarkably augmented. On the other hand, the cyto- and genotoxicity were suppressed by addition of NAC in the adenocarcinoma cells. Two contrasting experiments: overexpression of NQO1 in CHO-K1 cells which originally expressed low NQO1 levels, and knock‐down of NQO1 in the adenocarcinoma cell line A549 by transfection of RNAi, also showed that NAC suppressed 9,10-PQ-induced toxicity in cell lines expressing high NQO1 activity and enhanced it in cell lines with low NQO1 activity. The results suggested that dual effects of NAC on the cyto- and genotoxicity of 9,10-PQ were dependent on tissue-specific NQO1 activity. -- Highlights: ► NAC augmented the cytotoxicity of 9,10-PQ in skin cell lines. ► 9,10-PQ-induced DSBs accompanying γ-H2AX were also augmented by NAC. ► NAC suppressed the cyto- and genotoxicity of 9,10-PQ in adenocarcinoma cell lines. ► The dual effects of NAC on toxicity of 9,10-PQ were dependent on NQO1 activity.

Reaction of anhydrous RhCl3 with PQ and PPh3 in boiling ethanol affords the dark brown paramagnetic complex, cis-[Rh(PQ)(PPh3)2Cl2] (3) in good yields. Diffusion of iodine solution in n-hexane to the trans-[Os(PQ) (PPh3)2(CO)(Br)] solution in CH2Cl2 generates the crystals of trans-[Os(PQ)(PPh3)2(CO)(Br)](+)I3(-), (4(+))I3(-)), in lower yields.

Two comparatively longer C-O (1.286(4) Å) and the shorter C-C lengths (1.415(7) Å) of the OO-chelate of 1·2toluene and 2·CH2Cl2 and the isotropic fluid solution EPR signal at g = 1.999 of 3 are consistent with the existence of the reduced PQ(˙-) ligand in 1-3 complexes. Anisotropic EPR spectra of the frozen glasses (g11 = g22 = 2.0046 and g33 = 1.9874) and solids (g11 = g22 = 2.005 and g33 = 1.987) instigate the contribution of the resonance form, cis-[Rh(II)(PQ)(PPh3)2Cl2] in 3. DFT calculations established that the closed shell singlet (CSS) solutions of 1Me and 2Me are unstable due to open shell singlet (OSS) perturbation. However, the broken symmetry (BS) (1,1) Ms = 0 solutions of 1Me and 2Me are respectively 22.6 and 24.2 kJ mole(-1) lower in energy and reproduced the experimental bond

    Full Text Available In case of price-regulated companies it is the role of appropriate government agencies to introduce clear, internally consistent, theoretically sound, and unambiguous methodology for finding the regulative cost of capital. The aim of the paper is to describe and analyze the cost of capital estimation methodology for regulated companies in Estonia and discuss some issues arising in applying this methodology. The current paper focuses on two topical issues associated with the estimation of regulative cost of capital in Estonia: estimation of market risk premium and inclusion of currency risk premium into the cost of capital. Current turmoil in financial markets has increased investors’ risk aversion as well as level of risks.

    Full Text Available his article provides an assessment of labour market adjustments occurring in Estonia during the 2008/2011 crisis. The strategy of internal devaluation succeeded in shrinking the real (hourly unit labour costs by 25 % per year in 2010 and 2011, thus helping Estonian enterprises gain international competitiveness. The whole gamut of tools available in terms of flexibility was used, at least in the worst time of the financial crisis: massive lay-offs, reduced working time and wage cuts. In 2011, Estonia stood as one of the most dynamic EU countries to recover with exports growth. On the social side, however, the track record is not positive: the purchasing power of workers has been reduced and unemployment still remains strong and persistent despite economic recovery.

    Mokrik, Robert

    2009-09-01

    Full Text Available Identification of the barium occurrence and its origin is made on the basis of the groundwater chemistry study. High Ba content has been detected in the Cambrian–Vendian aquifer system in the coastal vicinity of the Gulf of Finland in Estonia and St Petersburg. The dissolution of Ba from witherite as the primary source was derived from the analysis of the aqueous solution equilibrium with Ba-related minerals. It is reflected in the chemical composition of groundwater and influenced by the galenite–calcite–fluorite polymetallic mineralization in Vendian sandstones. The dissolution and re-deposition of carbonates and baryte are confirmed by mineral saturation states for an aqueous solution and distribution of other species in the groundwater of the Cambrian–Vendian aquifer system in North Estonia.

The analysis is conducted with two principal research objectives in mind. Firstly, to explain how e-participation has fared in Estonia, both in terms of citizen mobilization and government responses. The second goal is to evaluate a series of procedural and technological changes for enhancing e-participation. The Estonian case provides ample lessons for ensuring that e-participation in practice can better meet the expectations of users and government officials alike.

    The report presents a historical survey on two of the nuclear facilities under the IAEA safeguards in Estonia - Sillamaee Uranium Extraction Factory and the Paldiski Submarine Training Centre. These facilities were a Soviet legacy and shall be decommissioned and it is only through a close international co-operation and technical assistance that it would be possible to solve all the problems arising at these facilities. The historical survey represents the best available information the authors were able to give on the nuclear facilities, which have functioned on the territory of Estonia. The historical survey was a joint co-operation initiative by the Estonian Radiation Protection Centre and the Swedish Nuclear Power Inspectorate. The historical survey will be presented to the IAEA as a volunteer supplement to the State Declaration according to the Additional Protocol (author)

  13. Spatial Planning in Estonia – From A Socialist to Inclusive Perspective

    2016-02-01

    Full Text Available Spatial planning in Eastern Europe has gone through major changes during the years after the Soviet occupation ended around 1990. New planning standards were eagerly accepted but the practice was often carried out in a socialist manner. This article gives an overview of planning law and practice in Estonia during the transition period. The example presented is a district in Tartu, the second largest city of 100,000 inhabitants. The article analyses different master planning documents covering the whole district and compares both their process of compilation and their content to former Soviet era plans. The conclusion is that the transition from socialist to inclusive planning in Estonia has taken at least two decades, and the process is still not fi nished. This shows that the legal framework alone is not suffi cient to transform planning practice – a new ideology has to be accepted by the specialist as well as the politicians and the general public.

    Carcasses of 26 wolves were collected during the 2000/2001 and 2003/2004 hunting seasons and examined for helminths. Thirteen helminth species were recorded: one trematode (Alaria alata), seven cestodes (Diphyllobothrium latum, Mesocestoides lineatus, Taenia hydatigena, Taenia multiceps, Taenia ovis, Taenia pisiformis, and Echinococcus granulosus), and five nematode species (Uncinaria stenocephala, Toxascaris leonina, Toxocara canis, Trichinella nativa, and Trichinella britovi). The most common species were A. alata and U. stenocephala. Mature Echinococcus granulosus was found and described for the first time in Estonia, and its identity verified using PCR-RFLP analysis. Sequencing a fragment of the mitochondrial DNA NADH dehydrogenase 1 (mtND1) gene showed that the E. granulosus strain from Estonia was identical to strain G10, recently characterized in reindeer and moose in Finland.

    Full Text Available Corporate longevity is - in essence - determined by a company's intrinsic competitive advantage (sometimes dubbed a "moat" as well as exogenous factors: from business doing ease - to broader, macroeconomic and strategic factors. In this study, we have endeavoured to compare the business environments and corporate sectors of two recent entrants into the European Union: Estonia and Poland. Overall, Estonia, thanks to greater resolve in post-communist liberal transition, has consistently ensured a superior corporate governance framework. Surprisingly, it is the macroeconomic and strategic steadiness that led to higher corporate survival in Poland. The global economic crisis of 2007-2009 is expected to further back this claim, as the patterns of macroeconomic growth for both countries are set to widen.

    To describe alcohol policy changes in parallel to consumption changes in 2005-2010 in Estonia, where alcohol consumption is among the highest in Europe. Review of pertinent legislation and literature. Alcohol consumption decreased since 2008, while alcohol excise tax, sales time restrictions and ad bans have increased since 2005. An economic downturn started in 2008. The precise roles of policy changes and the economic downturn in the decline of alcohol consumption, and whether the decrease will be sustained, are still unclear.

    Although sheep (Ovis aries) have been one of the most exploited domestic animals in Estonia since the Late Bronze Age, relatively little is known about their genetic history. Here, we explore temporal changes in Estonian sheep populations and their mitochondrial genetic diversity over the last 3000 years. We target a 558 base pair fragment of the mitochondrial hypervariable region in 115 ancient sheep from 71 sites in Estonia (c. 1200 BC–AD 1900s), 19 ancient samples from Latvia, Russia, Poland and Greece (6800 BC–AD 1700), as well as 44 samples of modern Kihnu native sheep breed. Our analyses revealed: (1) 49 mitochondrial haplotypes, associated with sheep haplogroups A and B; (2) high haplotype diversity in Estonian ancient sheep; (3) continuity in mtDNA haplotypes through time; (4) possible population expansion during the first centuries of the Middle Ages (associated with the establishment of the new power regime related to 13th century crusades); (5) significant difference in genetic diversity between ancient populations and modern native sheep, in agreement with the beginning of large-scale breeding in the 19th century and population decline in local sheep. Overall, our results suggest that in spite of the observed fluctuations in ancient sheep populations, and changes in the natural and historical conditions, the utilisation of local sheep has been constant in the territory of Estonia, displaying matrilineal continuity from the Middle Bronze Age through the Modern Period, and into modern native sheep.

    Full Text Available The purpose of this study was to assess exposure to drinking water fluoride and evaluate the risk of dental fluorosis among the Estonian population. The study covered all 15 counties in Estonia and 93.7% of population that has access to public water supplies. In Estonia groundwater is the main source for public water supply systems in most towns and rural settlements. The content of natural fluoride in water ranges from 0.01 to 7.20 mg/L. The exposure to different fluoride levels was assessed by linking data from previous studies on drinking water quality with databases of the Health Protection Inspectorate on water suppliers and the number of water consumers in water supply systems. Exposure assessment showed that 4% of the study population had excessive exposure to fluoride, mainly in small public water supplies in western and central Estonia, where the Silurian-Ordovician aquifer system is the only source of drinking water. There is a strong correlation between natural fluoride levels and the prevalence of dental fluorosis. Risk of dental fluorosis was calculated to different fluoride exposure levels over 1.5 mg/L.

  4. The Phenomenon of Trust in Flat Owners’ Collective Renovation Strategies in Estonia

    Directory of Open Access Journals (Sweden)

    Liis Ojamäe

    2015-12-01

    Full Text Available Mobilising fl at owners into renovating residential blocks in post-socialist countries has been a complicated process. Evidence from Estonia shows that the success of collective renewal strategies depends not only on economic issues but also on ways investments are organised and, signifi cantly, the relationship of trust between diff erent actors. The paper aims at conceptualising the issue of institutional trust upon the experience of urban housing renewal in Estonia. It is contended that trust is crucial for the joint decision-making in a block as well as for facilitating negotiations between fl at owners’ associations, local municipalities and market actors. The paper draws on three qualitative studies conducted in Estonia during the 2000s, which allow asserting that trust towards new strategies of housing renewal can be achieved and maintained by ‘best practices’, which by concentrating expert knowledge also denote direct communication between experts and fl at owners. While it is important to raise the residents’ technical knowledgeability, it is indispensable to develop abilities to manage and communicate the renovation process between diff erent parties. The public sector is conceived to be a central actor in sustaining trust between actors who have no previous positive experience from collective residential strategies

    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.

    2012-04-01

    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.

  8. The state-church relations in Estonia during the years 1944 - 1953

    Full Text Available The article features an analysis of the nature and dynamic of church-state relations in Estonia during the first years following its integration into the USSR. In 1944 the religious situation in the republic was characterized by a number of distinctive attributes. The local population, which had lived prior to the accession of the Baltics to the USSR in 1944 in an atmosphere of relative religious freedom, presented the Soviet authorities with a new phenomenon that would have to be reckoned with. The Plenipotentiaries for Estonia appointed by the Council on ROC Affairs at the USSR Council of Ministers were able to convince their superiors of the need to tread carefully in light of the local specifics. The article deals with an analysis of the distinctive features of the Estonian Orthodox Church. As a secondary denomination in the region, it felt the powerful influence of Lutheran customs and rites. The ethnic heterogeneity of the fold and pronounced language barrier determined the choice of candidacy for the ruling eparchy. The Estonian diocese was rather well endowed with cathedrals, meaning that the main problem of church life in the USSR since the easing of persecution in 1944-1947 - the opening of new parishes - was not an issue in Estonia. On the whole, the church-state relations that dominated the republic in 1944-1947 were quite stable, just as they were around the country; moreover, they were typified by a cautious policy on the part of the Soviet authorities. In 1948-1949 the situation began to deteriorate across the country and Estonia was no exception. The difference was in the methods used: in Estonia, the decision was made to fight the Church and its clergy primarily through collectivization, which was actively pursued in the Baltics beginning in the early 1950s. Collectivization left rural parishes and their clergy in dire straits, and religious life in the countryside began to wane. Yet, the arrival from the central regions

    Maret Güldenkoh

    2014-12-01

    Full Text Available Family enterprise is a business entity that belongs to the family. In Estonia the concept of family business, family entrepreneur, or family enterprise has not been defined in legislation. The concepts of business and enterprise have been defined in several pieces of law with some dissensions in their interpretations, however. Differences in legal definitions become obvious when transferring a business. The aim of the article is to assess the legislative conditions of family enterprises in Estonia. Family enterprises can be transferred either by way of transferring the holding status or by transferring the enterprise. Holding can be transferred in companies; a sole proprietor should transfer the business entity either as a whole or transfer the business entity into a company to have a holding there. Family businesses operating as sole proprietors may incur tax liability by transferring the family enterprise. The paper outlines special features of transferring enterprises, including family enterprises in Estonia. Business transfers have been few and there is no unambiguous practice in this sphere. Transfer of family enterprises is identified with transfer of enterprises; differences arise when family business has been registered as a sole proprietor. The paper provides a brief description of the differences in transferring enterprises, including family enterprises in Estonia. A purpose was to evaluate the legal environment of transferring family enterprises. In Estonia guidelines should be formulated for transferring the business of a self-employed family member and legal regulations should be introduced to avoid ill-intentioned transfer of enterprises.

    2012-04-01

    Full Text Available This article discusses the position of Young Estonia (Noor-Eesti in four different fields of influence: 1. What is the position of the Young Estonia movement in literary history, i.e. in the different monographs and articles on Estonian literature? What position is given to the movement by the writer(s of the various sketches on Estonian literature between 1908 and 2007, and how important are the writers of the group in the eyes of literary historians? 2. How is the movement represented in the collective (public memory of Estonia, e.g. do we find members of the movement on stamps or banknotes or in street names? 3. How do people in Estonia remember the literary production of the members of the group: what are the most important texts people read today, and how are these texts linked to the Young Estonia movement? 4. Finally, how is the movement represented outside Estonia, i.e. in the reception of Estonian literature abroad? Which texts have been translated, which authors are well-known abroad? In answering these questions the author concludes that the Young Estonia movement was much less important than has been assumed with respect to the production of literature, i.e. yielding literary texts that have been recognized and read up till the present. Rather, the lasting importance of Young Estonia has been in the organization of literary life.

    Full Text Available According to the Eurobarometer (European Commission, 2010, 39% of the Estonian adult population is not physically active at all. This percentage is relatively high compared to other countries that are culturally close to Estonia; the corresponding figure of close neighbors Finland and Sweden is below 10%. The article aims to present the results of a survey of physical activity (n=1,009 conducted in Estonia in 2013 and analyzes physical activity levels across various social groups. The results of the article show that employment, age, education, and ethnicity are important factors for engaging in leisure-time physical activity in Estonia. Non-ethnic Estonians, the less educated, the elderly, the unemployed, and those on maternity leave are less engaged in regular leisure exercise than people in other social groups. The results of the article were used to develop Estonia’s Sports 2030 strategy.

    Full text: The Sillamaee Metallurgical Plant was built in 1946-1948 at Sillamaee, in North-East Estonia, ca 190 km from Tallinn. Target product was uranium, mostly in form of yellow cake (U 3 O 8 ) for Soviet nuclear program. Uranium ore processing continued from 1948 to 1977, totally 4,013,000 tons of uranium ore were processed at Sillamaee plant. In early 1970s the plant introduced a new production line - rare earth elements. Rare earths were until 1991 produced from loparite (later from semi-processed loparite) - rare earths, niobium, tantalum and NORM-containing ore for Kola peninsula, Russia; later. All wastes were, as typical to hydrometallurgical processing all over the world, discharged to a large, 40 ha liquid waste depository - tailings pond, what in Sillamaee case was designed to discharge all liquid constituents slowly to the Baltic Sea. All uranium related activities were stopped in 1990, when only rare earth and rare metal production lines remained operational. The plant was 100 % privatized in 1997 and is today operated by Silmet Ltd., processing annually up to 8 000 tons of rare earth and 2000 tons of niobium and tantalum ores. Like all industries, inherited from Soviet times, Silmet plant is today facing a serious challenge to upgrading technologies towards waste minimizations process efficiency. The historical tailings pond, containing ca 1800 tons of natural uranium and ca 800 tons of thorium, was found geotechnically unstable and leaking to the Baltic Sea, in mid 90s. Being a problem of common Baltic concern, an international remediation project was initiated by Estonian Government and plant operator in 1998. In cooperation with Estonian, Finnish, Swedish, Danish and Norwegian Governments and with assistance by the European Union, the tailings pond will be environmentally remediated - dams stabilized and surface covered, by end of 2006. Close-down and environmental remediation of the tailings pond provides plant an ultimate challenge of

This article undertakes to juxtapose Young Estonia’s efforts at cultural renewal, its rhetoric of the future, and futurism as a cultural phenomenon. (As such, futurism was vitally engaged with contemporary urban culture, industry, and technology. Four parameters serve as points of departure: (1 Young Estonia’s rhetoric of the new and the future. Though specific about what they rejected, Young Estonia’s texts do not outline a clear vision of the future. Frequently used key words for what they opposed included German- or Russian-mindedness, a people in servitude, the old, flat land, the lack of a unified whole, lack of style. (2 The place of the city in Young Estonia’s texts. Though in earlier publications there were only a few passing references to urban culture, the problems of the city come to the fore in several programmatic texts and in the visual design of the fourth Young Estonia album in 1912. By then the core members of Young Estonia also had had real experience of a large metropolis. If their earlier attitude toward the city had been critical, then in these Young Estonian texts the city finds its positive face. (3 Industry and the proletariat. The Young Estonia movement received stimulus from such general phenomena as factories, technology, and industry. In their imagination working people and educated people seem to live in separate worlds, with different wishes and needs. However, the freedom of the educated would be impossible without political freedom. Although they believed that technological development was a precondition for the creation of urban culture, neither their own literary works nor their other aspirations bore this out.

    First Estonian uranium, produced in a pilot plant at Narva, was presented to Soviet military administration in 1945 and just a year later - 1946 - installation of an uranium production plant was started at Sillamaee, Estonia. Estonian local ore - alum shale - containing only 0,026% of uranium was used for uranium production for nearly five years, after the plant was launched in 1948. The uranium mine, having been activated from 1947 to 1952, was left in status of 'active conservation' for 17 years, until finally closed in 1969. Potential threats of this hidden legacy have never been revealed. After close-down of local uranium mine, more than 4 million tons of ore, imported mostly from Central and East European countries: Czechoslovakia, Hungary and Eastern Germany were processed at Sillamaee. These activities have left a large tailings impoundment with the total volume of ca. 8 million cubic meters in the immediate vicinity of the Baltic Sea. Today the plant is privatized, converted to civil purposes and provides together its power generating facilities ca. 1200 jobs in the socially sensitive area of North-East Estonia, while environmental hazards of the history, however, remain: - Continuous seepage of tailing waters into the sea contributes and would contribute over long term to the pollution of the Baltic Sea; - stability of the tailings dam seaside under present conditions can not be guaranteed thus risking a sudden release of partly liquid tailings due to potential dam failure; - uncovered surface of the tailings presents a health hazard due to dusting and radon release and hinders the revitalization of the area. The conceptual design of the Estonia's largest environmental remediation project, done by Wismut, is now complete and first implementation steps are underway. The project for mine area restoration is in initiation phase; it shall reveal the current and potential environmental hazards of the facility and create the concept for necessary rehabilitation

    1999-01-01

    Quick launch of the nuclear program was a high priority for the Soviet military, as a uranium production plant installation was started at Sillamae, Estonia, in 1946. Estonian local ore - alum shale - containing only 0.03% of uranium was used for uranium production for nearly five years, after the plant was launched in 1948. Altogether more than 4 million tons of ore, imported mostly from Central and East European countries (Czechoslovakia, Hungary and Eastern Germany) were processed at Sillamae. These activities have left a large tailings impoundment with the total volume of ca 8 million cubic meters in the immediate vicinity of the Baltic Sea. Today the plant is privatized, converted to civil purposes and provides ca. 1200 jobs in the socially sensitive area of North-East Estonia, while environmental hazards from the past; however, remain: Continuous seepage of tailing waters into the sea contributes and would contribute over long term to the pollution of the Baltic Sea; stability of the tailings dam seaside under present conditions can not be guaranteed thus risking a sudden release of partly liquid tailings due to potential dam failure; and uncovered surface of the tailings presents a health hazard due to dusting and radon release and hinders the revitalization of the area. The conceptual design of the Estonia's largest environmental project is now complete, the completion of practical remedial works by the end of 2005 will render Sillamae project a pioneer among Central and East European restoration projects of this character. This paper presents characteristic features of Sillamae remediation project, planning the use of best technical solutions, especially considering the vulnerability of geotechnical stability.

    Full Text Available The earliest cornulitid Cornulites sp. appears in the Darriwilian (Lasnamägi Regional Stage of Estonia. Internal annulation is present in all Middle Ordovician cornulitids and could be a plesiomorphic character for the group. The encrusted trilobites are rare in the Ordovician of Estonia. Illaenid pygidia and cranidia were encrusted by cornulitids and trepostome bryozoans. The encrustation of both Middle Ordovician and Late Ordovician trilobites took place post mortem. The studied hard substrate communities of Middle Ordovician and Late Ordovician trilobite pygidia and cranidia are typical of the Ordovician.

  4. Application of spherical fly-ash particles to study spatial deposition of atmospheric pollutants in northen-eastern Estonia

    2000-01-01

    Spherical fly-ash particles, emitted to the atmosphere in the high-temperature combustion process of fossil fuels, were found in considerable amounts in analysed snow samples of north-eastern Estonia. Spatial deposition of particles in snow cover is compared with the results of surface sediment samples of lakes. The results from snow characterise well the distribution of pollution sources and the distance from the main power plants in north eastern Estonia. Variations in particle deposition of closely situated snow samples were found to be negligible. Fly-ash particle influxes in snow samples correlate well with modelled maximum concentration fields of flyash in the near-surface air layer. (author)

    2001-01-01

    In Estonia oil shale is produced by underground and surface mining. The excavation methods used cause serious damage to the environment, especially to the topography, which hampers the further use of the mined-out areas. The oil shale mining has a serious impact on the environment also due to the pollution of surface and groundwater by polluted mine drainage waters, lowering of groundwater level, changing of soil properties and high air pollution rate. Decline in mining activities and the introduction of new technologies together with economic measures has improved the situation but much should be done during coming years. (author)

    Quality control measurements of X ray diagnostic units were carried out in four hospitals in Estonia. Measurements were focused on the unit's technical performance, on image quality and on patient dose and film processing. The main problems are in the areas of image receptors and film processing: image receptors are of low speed type causing high patient doses and manual film processing results in low contrast and high base plus fog. Spatial resolution, both in film imaging and in image intensifiers, is reasonably good. It is recommended that quality assurance programmes be established, that basic measuring equipment be acquired and personnel assigned to perform such measurements be trained. (Author)

    Estonia ranks consistently on top of the list of countries with the largest gender pay gap. However, irrespective of abundant aggregate level evidence, little is known what motivates the gap at the individual level. In this paper we precisely address the issue of gender pay gap at the individual level. We examine how large is the gender pay gap in actual and expected wages and how it can be explained. We use a rich dataset from Estonian Labour Force Survey on actual wages, and the data from C...

  11. First union formation in Estonia, Latvia and Lithuania: patterns across countries and gender

    2007-11-01

    Full Text Available This article examines the transformation of first union formation in the Baltic countries between the late 1960s and early 1990s, in the context of societal and family-level gender relations. The analyses employ microdata from the European Family and Fertility Surveys program. Our results on the trends indicate that in Estonia and Latvia the shift from direct marriage to cohabitation started well before the fall of socialist regime. Event-history models provide support for a hypothesised association between union formation and gender system, with Lithuania showing more traditional features in both respect, plausibly embedded in long-standing cultural differences between the countries.

    The chemotherapeutic agent 6-mercaptopurine (6-MP) has been shown to react covalently with the ultimate carcinogenic metabolite of benzo[a]pyrene, 7-r,8-t-dihydroxy-9-t,10-t-oxy-7,8,9,10-tetrahydrobenzo[a]pyrene (BPDE), in aqueous solution, forming a single adduct. NMR studies of the HPLC-purified product were consistent with its identification as 10(S)-(6'-mercaptopurinyl)-7,8,9-trihydroxy-7,8,9,10- tetrahydrobenzo[a]pyrene. Reaction kinetics were analyzed by using both HPLC separation of the products formed and a spectrophotometric assay for adduct formation. A simple model in which direct reaction between 6-MP and BPDE takes place without formation of a physical complex was found to adequately predict the dependence of product ratios on 6-MP concentration. Variations in the observed rate constant for this reaction with changes in temperature, pH, and buffer concentration were determined and compared to the effects of these variables on the observed rate constant for BPDE hydrolysis. In each case, the processes were affected quite differently, suggesting that different rate-determining steps are involved. The data suggest that the reaction mechanism involves SN2 attack of the anion of 6-MP, formed by ionization of the sulfhydryl group, on carbon 10 of BPDE, resulting in a trans-9,10 reaction product.

    The long natural history of prostate cancer (CaP) limits comparisons of efficacy between radical prostatectomy (RP) and external beam radiotherapy (EBRT), since patients treated years ago received treatments considered suboptimal by modern standards (particularly with regards to androgen deprivation therapy [ADT] and radiotherapy dose-escalation]. Gleason score (GS) 9-10 CaP is particularly aggressive, and clinically-relevant endpoints occur early, facilitating meaningful comparisons. To compare outcomes of patients with GS 9-10 CaP following EBRT, extremely-dose escalated radiotherapy (as exemplified by EBRT+brachytherapy [EBRT+BT]), and RP. Retrospective analysis of 487 patients with biopsy GS 9-10 CaP treated between 2000 and 2013 (230 with EBRT, 87 with EBRT+BT, and 170 with RP). Most radiotherapy patients received ADT and dose-escalated radiotherapy. Kaplan-Meier analysis and multivariate Cox regression estimated and compared 5-yr and 10-yr rates of distant metastasis-free survival, cancer-specific survival (CSS), and overall survival (OS). The median follow-up was 4.6 yr. Local salvage and systemic salvage were performed more frequently in RP patients (49.0% and 30.1%) when compared with either EBRT patients (0.9% and 19.7%) or EBRT+BT patients (1.2% and 16.1%, pRadiotherapy and RP provide equivalent CSS and OS. Extremely dose-escalated radiotherapy with ADT in particular offers improved systemic control when compared with either EBRT or RP. These data suggest that extremely dose-escalated radiotherapy with ADT might be the optimal upfront treatment for patients with biopsy GS 9-10 CaP. While some prostate cancers are slow-growing requiring many years, sometimes decades, of follow-up in order to compare between radiation and surgery, high-risk and very aggressive cancers follow a much shorter time course allowing such comparisons to be made and updated as treatments, especially radiation, rapidly evolve. We showed that radiation-based treatments and surgery

    2014-03-01

    Full Text Available The aim of this paper is to analyze several aspects of digital publishing markets in Baltic countries. Estonia, Latvia and Lithuania have their own languages, so there are three different publishing markets. Results show that there are significant differences in the number of available titles, despite the fact that the Baltic e-book market is relatively new. The research on e-book sales identified the main e-book retailers and publishers in Baltic countries. E-books in Lithuanian, Latvian and Estonian available on sale were counted and the differences between e-book formats and the pricing in each country were established. The results showed that the smallest Baltic country, Estonia, has more e-books on sale than both Latvia and Lithuania. It is difficult to say if Latvia even has an e-book market at all. Lithuania is somewhere in the middle. Finally, an overview of the largest retailers and publishers is provided and overall publishing dynamics within the past 20 years is described.

    2010-05-01

    Full Text Available The 20th century saw the Soviet and Francoist regimes enforce their respective ideologies in Estonia and the Catalan-speaking territories in Spain. In both cases, the autochthonous language suffered under the stringent control of the mechanisms of censorship and repression. In fact, Soviet and Spanish leaders—representing both extremes of the political spectrum—tried to replace the use of the autochthonous language in many sociolinguistic domains with their own—Russian and (Castilian Spanish—as these languages embodied the ideologies and the new orders that they wished to establish. This paper compares and contrasts the diverse methods of control over language carried out in Estonia and the Catalan-speaking areas of Spain in order to demonstrate that highly centralised multilingual states—whatever their political ideology—can make use of surprisingly similar means of control, ultimately depriving local linguistic communities of the ability to use and develop their own language.DOI: http://dx.doi.org/10.5128/ERYa6.16

    2018-03-01

    Full Text Available Despite the abundance of research on disadvantaged minority group members, the research field on the ramifications of low group status is largely split between more material and psychological lines of explanation. There is also a lack of research on how subjectively perceived socio-economic status and discrimination cumulatively affect the sense of national belonging of ethnic minority group members. This survey study was conducted among Russian-speaking immigrants in Finland ('N' = 316 and Estonia ('N' = 501. The results in Estonia showed that for national identification to be high, both indicators of subjective group status had to be perceived as relatively high. In Finland, there was no interaction between the two indicators of subjectively perceived low group status. The study shows how perceptions of cumulative disadvantage may provoke a backlash in the form of immigrants’ psychological distancing from the national ingroup. The findings are discussed in relation to the pervasiveness of low status in different intergroup contexts and minority group members’ perceived investments to society.

    Proliferative kidney disease (PKD) caused by the myxozoan parasite Tetracapsuloides bryosalmonae is a serious parasitic disease threatening both farmed and wild salmonid populations, but very little is currently known about the distribution of the parasite in the Baltic Sea region. In this study we (1) report the development of a novel multiplex PCR method for fast and reliable screening of T. bryosalmonae; (2) use this multiplex PCR method to show that the PKD agent T. bryosalmonae is widespread in natural brown trout Salmo trutta L. populations in Estonia; (3) evaluate monthly and yearly variation of T. bryosalmonae prevalence in juvenile trout; (4) assess T. bryosalmonae prevalence in different age-classes of fish (0+ vs. 1+ and older) and report the presence of the PKD agent in the kidneys of returning sea trout spawners; and (5) suggest the freshwater bryozoan Plumatella fungosa as a putative invertebrate host of T. bryosalmonae in Estonia. Our results demonstrate a highly heterogeneous distribution of T. bryosalmonae at the micro-geographic scale, indicating that PKD could have an important negative effect on recruitment in Estonian brown trout populations.

    Full Text Available This article deals with the changes that have taken place in the Supilinn district in Tartu, Estonia due to the gentrification process. The gentrification process affects the cultural, social, economic, and physical environment of the area. People have been interested in this topic since the 1960s. Nowadays, there is also reason to discuss this issue in the context of Estonia and of the Supilinn district. Studying and understanding the processes that take place in the living environment, provides an opportunity to be more aware about them and to influence the development of these processes. This article provides an analysis of the conditions necessary for gentrification in the Supilinn district, describes the process of gentrification, and tries to assess the current developmental stage of the gentrification process. Cities are shaped by their people. Every area has a unique look that is shaped not only by the physical environment, but also by the principles, values, and wishes of its residents. Local residents influence the image of the mental and the physical space of the area. What changes has the development of the Supilinn district caused in the population of the area, and how have the residents, in turn, changed the district?

    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.

    Full Text Available To investigate the impact of different cropping systems, the pests, their hymenopteran parasitoids and predatory ground beetles present in two spring rape crops in Estonia, in 2003, were compared. One crop was grown under a standard (STN cropping system and the other under a minimised (MIN system. The STN system plants had more flowers than those in the MIN system, and these attracted significantly more Meligethes aeneus, the only abundant and real pest in Estonia. Meligethes aeneus had two population peaks: the first during opening of the first flowers and the second, the new generation, during ripening of the pods. The number of new generation M. aeneus was almost four times greater in the STN than in the MIN crop. More carabids were caught in the MIN than in STN crop. The maximum abundance of carabids occurred two weeks before that of the new generation of M. aeneus, at the time when M. aeneus larvae were dropping to the soil for pupation and hence were vulnerable to predation by carabids.

    2015-06-01

    The importance of tightness-looseness as a dimension that explains a considerable amount of variance between cultures was demonstrated by Gelfand et al. (2011). Tight nations have many strong norms and a low tolerance of deviant behaviour, whereas loose nations have weak social norms and a high tolerance of deviant behaviour. The main aim of the current studies was to examine situational constraint in Estonia and Greece: that is, how the cultural dimension of tightness-looseness is manifested in everyday situations in those two countries. The findings of a questionnaire study (Study 1) suggested that, in general, there is higher constraint across everyday situations in Greece than in Estonia, but situational constraint in Greece is especially strong in school and organisational settings where people have hierarchically structured roles. The results of an observational study (Study 2) revealed a relatively high agreement between appropriateness of certain behaviours as judged by the respondents in Study 1 and the frequencies of observed behaviours in the two countries. Our findings suggest that the strength of situations may substantially vary both within and across cultures, and that the attitudes of the members about situational strength in their respective cultures are in concordance with observations of situations by neutral observers in how people in general behave in their culture. © 2014 International Union of Psychological Science.

    Full Text Available Gaining understanding about customers ’mindset and information on their experiences is a precondition for the formulation of an effective country branding strategy. What potential tourists might learn and how they can be made to feel about a place can help small and not very well-known countries compete with bigger and more popular tourist destinations. The article focuses on the effectiveness of Brand Estonia and claims that it is still a challenge, despite the existence of an ongoing strategy. It also favors the revision of the brand identity selection and the promotion of Estonian brand, and supports a customer-based approach for their assessment. Documentary and empirical evidence show that the image of Estonia among its most important target audiences in the field of tourism does not match the Estonian brand identity. The gap in-between was evidenced by the results and content analysis of 24 in-depth interviews made with a selected group of people well acquainted with the country as well as some branding experts. This article contributes to the existing case study literature with findings that also manifest opportunities to strengthen the country brand, if its formulation develops a realistic brand identity and its promotion is based on accurate, unique and appealing ideas. It proposes academic support to innovative or alternative concepts for the country branding, and comments on applications of this study to more specific fields and further research.

    The presence of Babesia spp. was studied in 2603 Ixodes ricinus and Ixodes persulcatus ticks collected at seven sites in Estonia. By reverse line blot screening, Babesia spp. was detected in 36 (1.4%) ticks, among them 18 (0.7%) were further recognized by a Babesia microti probe, 3 (0.1%) by a Babesia divergens probe, and the other 15 (0.6%) were recognized only by the universal Babesia spp. "catch all" probe. Sequence analyses of 6 of these 15 samples revealed that all of them belonged to Babesia sp. EU1. B. microti was detected in both tick species I. ricinus and I. persulcatus at the seven sites, whereas B. divergens-like and Babesia sp. EU1 were found only in I. persulcatus and I. ricinus, respectively. Genetic characterization based on partial 18S rRNA showed that the Estonian sequences of B. microti, B. divergens-like, and Babesia sp. EU1 share a high rate of similarity and are closely related to sequences from other European countries, Siberia, and United States. The present study demonstrated for the first time the existence and distribution of Babesia spp. in I. persulcatus and I. ricinus ticks in Estonia.

    This article is part of a long term project "Promoting the Occupational Well-Being of School Staff-Action Research Project in Finland and Estonia, 2009-2014." The purpose of this article is to describe the significance of action plans in the promotion of the occupational well-being of primary and upper secondary school staff in Finland and Estonia from 2010 to the turn of the year 2011-2012. An electronic open questionnaire was sent to occupational well-being groups in Finland (N=18) and in Estonia (N=39). In Finland, the questionnaire was responded to by 16 (n=16) occupational well-being groups, and in Estonia, by 38 (n=38) groups. The qualitative data were analyzed using the inductive-deductive method and content analysis. The obtained results indicate that the schools had named goals for action plans in all aspects of the promotion of occupational well-being in schools (worker and work, working conditions, professional competence, working community) and that these goals were mainly realized in the schools in a systematic way. Schools felt that the action plan for occupational well-being helped them to set goals for occupational well-being and that the planned actions were realized in a more systematic way than before.

    The Diels-Alder reaction between substituted anthracenes 1a-1j and 4-phenyl-1,2,4-triazoline-3,5 ( 2) is studied. In all cases except one, the reaction proceeds on the most active 9,10-atoms of substituted anthracenes. The orthogonality of the two phenyl groups at the 9,10-position of diene 1a is found to shield 9,10-reactive centers. No dienophiles with C=C bonds are shown to participate in the Diels-Alder reaction with 1a; however, the reaction 1a + 2 proceeds with the very active dienophile 2,4-phenyl-1,2,4-triazoline-3,5-dione. It is shown that attachment occurs on the less active but sterically accessible 1,4-reactive center of diene 1a. The structure of adduct 3a is proved by 1H and 13C NMR spectroscopy and X-ray diffraction analysis. The following parameters are obtained for reaction 1a + 2 ⇆ 3a in toluene at 25°C: K eq = 2120 M-1, Δ Hf ≠ = 58.6 kJ/mol, Δ Sf ≠ = -97 J/(mol K), Δ Vf ≠ = -17.2 cm3/mol, Δ Hb ≠ = 108.8 kJ/mol, Δ Sb ≠ = 7.3 J/(mol K), Δ Vb ≠ = -0.8 cm3/mol, Δ H r-n = -50.2 kJ/mol, Δ S r-n = -104.3 J/(mol K), Δ V r-n = -15.6 cm3/mol. It is concluded that the values of equilibrium constants of the reactions 1a-1j + 2 ⇆ 3a-3j vary within 4 × 101-1011 M-1.

    World Health Organization recommends exclusive breastfeeding for infants for the first 6 months of life, followed by introduction of nutritious complementary foods alongside breastfeeding. Breast milk remains a significant source of nourishment in the second half of infancy and beyond; however, it is not clear whether more breast milk is always better. The present study was designed to determine the association between amount of breast milk intake at 9-10 months of age and infant growth and development by 12-18 months of age. The study was nested in a randomized controlled trial conducted in Malawi. Regression analysis was used to determine associations between breast milk intake and growth and development. Mean (SD) breast milk intake at 9-10 months of age was 752 (244) g/day. Mean (SD) length-for-age z-score at 12 months and change in length-for-age z-score between 12 and 18 months were -1.69 (1.0) and -0.17 (0.6), respectively. At 18 months, mean (SD) expressive vocabulary score was 32 (24) words and median (interquartile range) skills successfully performed for fine, gross, and overall motor skills were 21 (19-22), 18 (16-19), and 38 (26-40), respectively. Breast milk intake (g/day) was not associated with either growth or development. Proportion of total energy intake from breast milk was negatively associated with fine motor (β = -0.18, p = .015) but not other developmental scores in models adjusted for potential confounders. Among Malawian infants, neither breast milk intake nor percent of total energy intake from breast milk at 9-10 months was positively associated with subsequent growth between 12 and 18 months, or development at 18 months. © 2018 John Wiley & Sons Ltd.

    Three new isomerically pure 1,7-disubstituted perylene-3,4,9,10-tetracarboxylic monoimide dibutylester derivatives namely; N-[2-(diethylamino)ethyl]-1,7-dibromoperylene-3,4,9,10-tetracarboxy monoimide dibutylester (PMD-1), N-[2-(diethylamino)ethyl]-1,7-di(4-tert-butylphenoxy)perylene-3,4,9,10-tetracarboxy monoimide dibutylester (PMD-2) and N-[2-(diethylamino)ethyl]-1,7-di(pyrrolidinyl)perylene-3,4,9,10-tetracarboxy monoimide dibutylester (PMD-3), have been synthesized and their electronic absorption spectra, and steady-state fluorescence were investigated experimentally as well as by using density functional theory (DFT) calculations. All three compounds show good solubility in toluene and chloroform. Attachment of two tert-butylphenoxy groups at the 1,7-positions in PMD-2 resulted in a red shifted absorption band with an absorption maximum at 518 nm. UV/Vis absorption spectrum of PMD-3 bearing electron donating pyrrolidinyl groups at the 1,7-positions shows a broad absorption band within the visible region, extending to red region. Absorption maximum of lowest energy transition now shifts to 653 nm. In addition to the S0 → S1 absorption bands, bands belonging to S0 → S2 electronic transitions were observed at 378, 386, and 411 nm for PMD-1, PMD-2, and PMD-3 respectively. Compounds PMD-1, PMD-2 and PMD-3 display low fluorescence quantum yields of 0.027, 0.040 and 0.001, respectively in chloroform. DFT calculations revealed that the attachment of electron donating groups at 1,7-positions of perylene core, results in an increase in frontier orbitals energy levels. Observed energy increase in HOMO level is larger in each case, compared to the energy increase in LUMO levels, due to the higher contribution of side groups to HOMO. DFT calculated band gaps for PMD-1, PMD-2 and PMD-3 are 2.68, 2.63 and 2.29 eV respectively.

    We report interfacial characterization of 3,4,9,10-perylene-teracarboxylic dianhydride (PTCDA)-based organic spin valves (OSV) dusted with a thin layer of partially oxidized alumina at the organic semiconductor (OSC)/ferromagnet (FM) interfaces. Up to 13.5% magnetoresistance is achieved at room temperature. X-ray photoelectron spectroscopy measurements reveal interfacial electronic interaction between PTCDA and FM while the application of a thin alumina layer at the PTCDA/FM interfaces prevents the electronic hybridization and effectively preserves the spin injection into the OSC spacer. This finding demonstrates the critical effect of interfacial structure on magnetotransport behavior in OSV.

    Transient absorption spectrum of triplet state of 9,10-anthraquinone-2-sulfonate (AQS) in aqueous solution has been investigated using 248 nm (KrF) laser photolysis. A whole transient absorption spectrum with absorption maxim at 380 nm and 580 nm has been assigned to triple AQS from detailed kinetic analysis of decay of 380 nm and 580 nm signals, which is the neat characteristic absorption of triplet AQS reported for the first time. In addition, the difference in feature of the spectrum of triplet AQS in H 2 O and that in CH 3 CN was eliminated by further study using 248 nm laser pulses

    In this paper, we have synthesized our simple twisting arylvinyl anthracene derivatives, 9-styrylanthracene (ASB), 9,10-bis(styryl)anthracene (SB), 9-(2-(naph- thalen-1-yl)vinyl)anthracene (ASN) and 9,10-bis((naphthalen-1-yl)vinyl)anthracene (SN), to demonstrate the effect of skeleton symmetry on optical and optoelectronic properties. The results showed that SB and SN are weak emission with the fluorescence quantum yields (Φ) of ca. 7% but ASB and ASN are highly fluorescent (Φ≈50%) in THF solution, although they all exhibit high solid-state fluorescence efficiencies (22~50%). Grinding could induce about 20 nm of spectral shift of ASB and ASN crystalline fluorescence, but SB and SN crystals hardly exhibit mechano- fluorochromic behavior. Furthermore, the evaporated films of SB and SN are fragile due to re-crystallization soon, but those of ASB and ASN are stable and could be used as the bulk emissive layer exhibiting commendable electroluminescent performances. This finding indicates that the geometric structures of conjugated skeletons could influence the electronic and aggregate structure of organic luminogens, and then alter their optical and optoelectronic properties.

    The interaction between 1,4-dihydroxy 2,3-dimethyl 9,10-anthraquinone (DHDMAQ) and tin dioxide nanoparticle (SnO 2 NPs) has been investigated using optical absorption and emission techniques. Tin dioxide nanoparticles have been synthesized by chemical precipitation method. The experimental results reveal that the fluorescence intensity of 1,4-dihydroxy 2,3-dimethyl 9,10-anthraquinone has been quenched as the concentration of the SnO 2 NPs increased. The Stern–Volmer plot indicates that SnO 2 NPs have dynamic quenching efficiency on the fluorescence nature of DHDMAQ. The obtained value of the association constant infers that there is an association between DHDMAQ and the SnO 2 nanoparticles. -- Highlights: • The interaction between DHDMAQ and SnO 2 NPs has been investigated using optical absorption and emission techniques. • The fluorescence intensity of the fluorophore has been quenched as the concentration of the SnO 2 NPs increased. • The Stern–Volmer plot indicates that SnO 2 NPs have dynamic quenching efficiency on the fluorescence nature of DHDMAQ

  11. Quinoidal Oligo(9,10-anthryl)s with Chain-Length-Dependent Ground States: A Balance between Aromatic Stabilization and Steric Strain Release

    KAUST Repository

    Lim, Zhenglong

    2015-11-12

    Quinoidal π-conjugated polycyclic hydrocarbons have attracted intensive research interest due to their unique optical/electronic properties and possible magnetic activity, which arises from a thermally excited triplet state. However, there is still lack of fundamental understanding on the factors that determine the electronic ground states. Herein, by using quinoidal oligo(9,10-anthryl)s, it is demonstrated that both aromatic stabilisation and steric strain release play balanced roles in determining the ground states. Oligomers with up to four anthryl units were synthesised and their ground states were investigated by electronic absorption and electron spin resonance (ESR) spectroscopy, assisted by density functional theory (DFT) calculations. The quinoidal 9,10-anthryl dimer 1 has a closed-shell ground state, whereas the tri- (2) and tetramers (3) both have an open-shell diradical ground state with a small singlet-triplet gap. Such a difference results from competition between two driving forces: the large steric repulsion between the anthryl/phenyl units in the closed-shell quinoidal form that drives the molecule to a flexible open-shell diradical structure, and aromatic stabilisation due to the gain of more aromatic sextet rings in the closed-shell form, which drives the molecule towards a contorted quinoidal structure. The ground states of these oligomers thus depend on the overall balance between these two driving forces and show chain-length dependence. © 2015 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim.

  12. Aggregation-enhanced emission and piezochromic luminescence of 9,10-bis(p-dibutylaminostyryl)-2,6-bis(p-t-butylstyryl)anthracene

    A cruciform 9,10-distyrylanthracene-containing luminogen, 9,10-bis(p-dibutylaminostyryl)-2,6-bis(p-t-butylstyryl)anthracene (DDC), has been synthesized and the optical properties investigated. The results show that DDC is an aggregation-induced enhanced emission (AIEE) and piezofluorochromic (PFC) dye. The fluorescence quantum yield in THF/water=1/9 (18.1%) is about 12-fold over that in THF (1.53%). PFC experiment shows that the fluorescence colors (emission spectra) of DDC solid change reversibly between orange-red (602 nm) and red (632 nm) emissions upon pressing and annealing. Wide-angle X-ray diffraction and differential scanning calorimetric analyses reveal that the grinding has induced the phase transition of DDC solid from pristine crystalline to ground amorphous states, and annealing could cause the re-crystallization of amorphized DDC solid. This transformation between crystalline and amorphous states is responsible for the reversible PFC behavior upon external stimuli. Highlights: • A two-dimensional cross-conjugated luminogen (DDC) was synthesized. • DDC exhibits aggregation-enhanced emission and piezofluorochromic behaviors. • DDC emits bluer light in the crystalline phase than in the amorphous phase. • The PFC mechanism is ascribed to grinding-induced amorphization.

  13. Provenance of zircon of the lowermost sedimentary cover, Estonia, East-European Craton

    1999-12-01

    Full Text Available Bulk and accessory mineral composition of fresh and weathered crystalline rocks, and sedimentary deposits overlying the crystalline-sedimentary unconformity have been examined in core samples from 28 drill holes in Estonia. Before the Late Vendian to Early Cambrian regional subsidence and sedimentation, the region represented a flat plateau within the Svecofennian Domain. Palaeo-and Mesoproterozoic crystalline rocks, regardless their different initial mineral composition, subcrop under the Upper Vendian/Lower Cambrian sedimentary cover as usually intensely weathered rocks (saprolites composed of residual quartz, altered micas and prevailing clay minerals mainly of the kaolinite group. Thus, the bulk mineral composition of any basement crystalline rocks imparts no specific inherited rock-forming minerals into the covering sedimentary rocks. From the variety of accessory and opaque minerals of crystalline rocks, only zircon populations survived in saprolites. Crystalline rocks of different origin yield different zircons. Relationships between the zircon typology of the basement rocks having specific areas of distribution and the sedimentary rocks immediately overlying those crystalline rocks were the main subject of this study. The result is that siliciclastic sedimentary rocks covering weathered crystalline rocks only in places inherited zircons with typological features characteristic of specific basement areas. In northeastern Estonia, local lenses of the Oru Member (the earliest Upper Vendian sedimentary rocks in Estonia resembling the debris of weathered crystalline rocks yield accessory zircon which in a 1-2 m thick layer above the basement surface is similar to the zircons of the underlying weathering mantle of certain crystalline rocks. In the next unit, the Moldova Member, up to 43 m above the basement surface, a mixture of zircons resembling those of various local basement rocks has been found. Further upwards, in the Vendian and Lower

  15. A mouse model of familial ALS has increased CNS levels of endogenous ubiquinol9/10 and does not benefit from exogenous administration of ubiquinol10.

    Directory of Open Access Journals (Sweden)

    Full Text Available Oxidative stress and mitochondrial impairment are the main pathogenic mechanisms of Amyotrophic Lateral Sclerosis (ALS, a severe neurodegenerative disease still lacking of effective therapy. Recently, the coenzyme-Q (CoQ complex, a key component of mitochondrial function and redox-state modulator, has raised interest for ALS treatment. However, while the oxidized form ubiquinone10 was ineffective in ALS patients and modestly effective in mouse models of ALS, no evidence was reported on the effect of the reduced form ubiquinol10, which has better bioavailability and antioxidant properties. In this study we compared the effects of ubiquinone10 and a new stabilized formulation of ubiquinol10 on the disease course of SOD1(G93A transgenic mice, an experimental model of fALS. Chronic treatments (800 mg/kg/day orally started from the onset of disease until death, to mimic the clinical trials that only include patients with definite ALS symptoms. Although the plasma levels of CoQ10 were significantly increased by both treatments (from <0.20 to 3.0-3.4 µg/mL, no effect was found on the disease progression and survival of SOD1(G93A mice. The levels of CoQ10 in the brain and spinal cord of ubiquinone10- or ubiquinol10-treated mice were only slightly higher (≤10% than the endogenous levels in vehicle-treated mice, indicating poor CNS availability after oral dosing and possibly explaining the lack of pharmacological effects. To further examine this issue, we measured the oxidized and reduced forms of CoQ9/10 in the plasma, brain and spinal cord of symptomatic SOD1(G93A mice, in comparison with age-matched SOD1(WT. Levels of ubiquinol9/10, but not ubiquinone9/10, were significantly higher in the CNS, but not in plasma, of SOD1(G93A mice, suggesting that CoQ redox system might participate in the mechanisms trying to counteract the pathology progression. Therefore, the very low increases of CoQ10 induced by oral treatments in CNS might be not sufficient to

    All four isomers of (Z)-3-cis-6,7-cis-9,10-diepoxyhenicosenes, 1-4, have been synthesized using D-xylose as the chirally pure starting material. D-Xylose was first converted to 2-deoxy-4,5-O-isopropylidene-3-t-butyldimethylsilyl-D-threopentose 11, via several steps of selective protection, dehydroxylation, and deprotection. Wittig coupling of 11 with nonyltriphenylphosphonium bromide followed by hydrogenation and acid catalyzed deprotection of hydroxyl groups yielded the chiral (2R,3R)-1,2,3-triol, 14, which was used as the precursor for the C-8 to C-21 unit of the (Z)-3-cis-6,7-cis-9,10-diepoxyhenicosenes. Selective tosylation of 14 followed by stereospecific cyclization yielded (2R,3R)-1,2-epoxytetradecan-3-ol, 16, which was then divergently converted to the t-butyldimethylsilyl ether 17 and tosylate 22, respectively. Establishment of the C-5 through C-7 unit of the target molecules was accomplished via regiospecific coupling of 17 with 1-t-butyldimethylsiloxy-2-propyne to form 18. Stepwise transformation of 18 via the formation of tosylate 19, desilylation, and stereospecific cyclization to form epoxy alcohol 20, followed by P2-Ni reduction yielded a key intermediate, allylic epoxy alcohol (Z)-2-(5S,6R)-cis-5,6-epoxyheptadecen-1-ol, 21. Similarly, the coupling of 22 with 1-t-butyldimethylsiloxy-2-propyne yielded 23, which was stereospecifically cyclized to form 24. Desilylation and P2-Ni reduction of 24 gave the antipodal intermediate, (Z)-2-(5R,6S)-cis-5,6-epoxyheptadecen-1-ol, 26. Asymmetric epoxidation of antipodes 21 and 26 with (L)- or (D)-diethyl tartrates resulted in the formation of diepoxy alcohols 27 and 29 from 21, and 33 and 31 from 26, respectively. Tosylation of these diepoxy alcohols followed by coupling with lithium dibutenyl cuprate yielded the four stereoisomers of (Z)-3-cis-6,7-cis-9,10-diepoxyhenicosenes, 1-4. Analysis of the retention characteristics of these materials revealed that one or both of the S*,R*,S*,R* stereoisomers comprise the

    Most biggest polluters of atmospheric air among Estonian enterprises are located in the north-eastern part of republic. Volatile gases, vapours and fly ash from thermal power plants, chemical and other industries form a considerable aerotechnogenic load upon landscapes and dwelling regions, reaching also the areas of Gulf of Finland, and even the neighbouring states. Complicated pollution situation needs serious attention and systematic air quality control, assessing, forecasting and management, which is now organized on local, regional and state levels. It is well-known that for studies of various pollution situations the atmospheric dispersion models will be used. This present article deals with the special imitation system for maintenance of information about polluters and air contamination state in North-East (NE) Estonia, also for estimation of pollutants spreading and overground concentration fields by computer-based modelling.

    were obtained by sending a 32-question questionnaire, based on an agenda developed through semistructured interviews, to all midwives in Estonia. A nominal group technique was employed with key stakeholders to determine the extent of their agreement with the questionnaire's major findings. RESULTS......: The response rate to the questionnaire was 75%. There was no significant association between work satisfaction and independent variables of age, ethnicity, work abroad, increased responsibility, and involvement in postpartum care and counseling. There was, however, a significant association between work...... satisfaction and salary. The group process revealed that although there is no agreement on the role of family doctors and midwives in antenatal care, there is a general agreement that midwives should be more involved in postpartum care and that their tasks need to be better defined. CONCLUSIONS: Almost half...

    BACKGROUND: Levels of overweight have increased and fitness has decreased in children. Potentially, these changes may be a threat to future health. Numerous studies have measured changes in body mass index (BMI), but few have assessed the independent effects of low fitness, overweight and physical...... inactivity on cardiovascular (CVD) risk factors. METHODS: A cross-sectional multi-center study including 1 769 children from Denmark, Estonia and Portugal. The main outcome was clustering of CVD risk factors. Independent variables were waist circumference, skinfolds, physical activity and cardio......-respiratory fitness. RESULTS: Both waist circumference and skinfolds were associated with clustered CVD risk. Odds ratios for clustered CVD risk for the upper quartiles compared with the lowest quartile were 9.13 (95% CI: 5.78-14.43) and 11.62 (95% CI: 7.11-18.99) when systolic blood pressure, triglyceride, insulin...

    Three structures (Neugrund, Kärdla, and Kaali) of proven impact origin make Estonia the most cratered country in the world by area. In addition, several candidate impact structures exist, waiting for future studies to determine their origin. This article is an overview of these proven and possible impact structures, including some breccia layers. It summarizes the information and descriptions of the morphology; geological characteristics; and mineralogical, chemical, and geophysical data available in the literature. The overview was prepared to make information in many earlier publications in local journals (many of which had been published in Estonian or Russian) accessible to the international community. This review summarizes the facts and observations in a historical fashion, summarizing the current state of knowledge with some additional comments, and providing the references.

    The present study focused on the identification of emotions in cross-cultural conditions on different continents and among subjects with divergent language backgrounds. The aim was to investigate whether the perception of the basic emotions from nonsense vocal samples was universal, dependent on voice quality, musicality, and/or gender. Listening tests for 350 participants were conducted on location in a variety of cultures: China, Egypt, Estonia, Finland, Russia, Sweden, and the USA. The results suggested that the voice quality parameters played a role in the identification of emotions without the linguistic content. Cultural background may affect the interpretation of the emotions more than the presumed universality. Musical interest tended to facilitate emotion identification. No gender differences were found.

    As the world's largest commercial oil shale reserve, the Estonian Oil Shale Deposit has been exploited since 1916. As a result of mining, storing of solid wastes from the oil shale separation, combustion in the power plants and its thermal processing, the landscape in northeastern Estonia has been essentially changed and the man-made landforms have developed: the new microreliefs of natural and artificial structure are formed, as well as 'mountainous' and hilly reliefs in the form of waste heaps, ash plateaus, coke-ash dumps etc. Deformed (stable) and undeformed (unstable) areas from underground mining currently cover about 220km 2 . About 90km 2 (80%) of the area damaged by open pits are recultivated and reformed as forested and agricultural (grassland) areas. The total area occupied by solid waste has reached up to 26km 2 . New technogenic landscape units, i.e. made by technical means, will essentially influence the environment

    The deposition loads of fly ash and sulfur have been high in the North-East Estonia since the late fifties, when the oil shale energetics, chemical and cement industry achieved the remarkable extent. The combined effects of both pollutants have seriously damaged sensitive ecosystems (forest on podsolic soils and bog). Most of sulphur deposition is closely related to the oil shale fly ash deposition. The main effects are related with alkalisation due to accumulation of fly ash components and the Sphagnum growth inhibition due to sulfur load. These effects have the time scale of several years or even more. The pollution loads have been changed during recent 40 years due to launching and reconstruction of enterprises (incl. purification systems) and variations of production capacity. First representative data on air pollution deposition originate from the middle of eighties. Only model estimations could be used to quantify the deposition fluxes before that time, as well as for assessing the future scenarios

    1999-01-01

    Systematic changes in some climate elements have become evident in Estonia during the latest decades; the greatest changes have been observed in March. Two possible causes may have led to the observed warming: changes in general atmospheric circulation and in radiation budget. Due to small solar evaluation and shortness of day the role of solar radiation in air temperature formation is not considerable in March. The absence of any significant trend in the time series of net long wave radiation in March seems to be caused by simultaneous and opposite influence of changes in downward and upward infrared radiation fluxes on temperature conditions near ground. In other seasons a significant increase in greenhouse effect has been established. Therefore, the changes in general atmospheric circulation should be considered the main reason of warming, while the role of solar radiation and greenhouse effect is not considerable in March

  6. Deterrence Dilemma in Latvia and Estonia: Finding the Balance between External Military Solidarity and Territorial Defence

    Full Text Available While potential threats from Russia and NATO collective defence commitments are similar for Latvia and Estonia, both countries have adopted different approaches in the balancing exercise between territorial defence and military solidarity. Notwithstanding their differences, both are by their nature fully non-aggressive – without room for pre-emptive initiatives, extra territoriality or asymmetrical tools. Given that in a case of a hypothetical large-scale conventional attack both countries would almost entirely have to rest on the allies, external military solidarity is essential. Until the Ukraine crisis, both offered more military solidarity towards their NATO allies than the latter offered to them. As the result of the Ukrainian crisis, allies became more military-solidary with the Baltic nations, especially having established the Enhanced Forward Presence, while Estonian and especially Latvian contributions to international missions and operations dropped. Therefore, it is suggested that both countries increase their efforts to the allied international endeavours.

    The decrease in fossil fuel and the environmental problems arising from their burning force the mankind to change the structure of energy production. In the Estonian primary energy balance of renewable natural resources wood and peat are on the first place with the percentage of ca 11%. Wind, water and solar energy have not up till now been widely used in Estonia. The foundation of a wind plant and the construction of bioenergy boiler plants are promising from the financial point of view. For the feedstock of bioenergy production, waste from logging and timber industry, energy fast-growing trees and grasses, bulrush and biogas produced by fermentation of organic matter, could be used. One of the options is to produce energy field crops - rape and turnip rape. The authors hope that this paper will emphasise the importance of conducting more extensive research of renewable energy resources and the introduction of such projects. (author)

    The application of ionizing radiation and radioactive material in fields such as medicine, industry, teaching and research is constantly increasing. Consequently, any country using ionizing radiation and radioactive material in these applications must ensure that they are used safely. In order to achieve this goal a country must establish appropriate national infrastructure related to radiation protection and safety. This requires appropriate regulatory mechanism together with an enforcement ability. The national infrastructure adopted in a country will depend on the actual needs of the country, the size and the complexity of the regulated practices and sources, as well as on the regulatory tradition in the country. The national infrastructure in Estonia comprises of three main components: legislation, regulatory authority, resources. (author)

  10. 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.

    Full Text Available The aim of this research was to ascertain the importance of intergenerational solidarity in communication within the family and childrearing among the Russians living in Estonia. Generations see the world differently enough. One of the reasons for that is individualistic worldview which characterizes not only the younger generation, but individualistic tendencies have percolated into other generationsas well. All generations admit the presence of a generation gap, but they disclaim presence of intergenerational conflict. At the same time respondents affirm that there is solidarity between generations in their families and it is based on love and respect. Solidarity between generations in families is revealed both on spiritual level (communicating, love, trust, mutual understanding, common interests as well as in real help given by generations to each other as far as homework, children's upbringing, and economical aid are concerned.

    Full Text Available In 2013 and 2015, the ECtHR in the famous case of Delfi AS v. Estonia recognised the possibility for a website operator to be liable for the delayed removal of illegal comments of internet users. In this case the ECtHR formulated criteria for a website operator’s liability for damage caused to a third party by its visitor comments. The judgment of 2016 in the case of MTE & Index v. Hungary the ECtHR modified the criteria for a website operator’s liability, interpreting it to the benefit of web managers. This article seeks to reveal the criteria for the liability of a website operator and to draw some general guidance that can be applied in similar cases.

  13. Dolomitization and sedimentary cyclicity of the Ordovician, Silurian, and Devonian rocks in South Estonia

    Kallaste, Toivo

    2006-03-01

    Full Text Available The distribution and composition of dolomitized rocks and stoichiometry of dolomite in southern Estonia in the Ordovician, Silurian, and Devonian were studied on the background of the facies, sedimentary cyclicity (nine shallowing-up cycles, and evolution of the palaeobasins. The composition of rocks and lattice parameters of dolomite were investigated using the X-ray diffraction, X-ray fluorescence, titration and gravimetric analyses, and porosity measurements. The formation of dolostones is directly determined by the cyclic evolution of palaeobasins. Dolomitized rocks belong to the shallow-water inner shelf or tidal/lagoonal facies belt of regressive phases of sedimentary cycles. Sediments of the deep shelf/transitional environment and transgressive phases are not dolomitized. The most stoichiometric is secondary replacive dolomite of Silurian and upper Ordovician dolostones, formed during the early diagenesis of normal-marine (saline shallow-shelf calcitic sediments. The content of insoluble residue does not affect the stoichiometry. The changes in lattice parameters are induced by the Ca/Mg ratio in the dolomite lattice. The dolomite of the dolostones contacting limestone or containing calcite has an expanded lattice. The primary (syngenetic dolostone of the lagoonal or tidal flat belt has also an expanded lattice. No dolomitizing effect of the waters of the Devonian palaeobasin on the underlying rocks was revealed. The whole data set of the studied dolostones is consistent with the marine water environment in the palaeobasin at the corresponding time and shows no sign of the inflow of external fluids. It suggests that the microbial model of dolomite formation may characterize the Ordovician, Silurian, and Devonian in southern Estonia. The occurrence of dolostones between undolomitized rocks limits the time of dolomitization to the early diagenetic stage.

  14. 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

    2010-06-01

    Full Text Available Reinvestigation of the late glacial Solova (Remmeski basin, based on plant macro­fossil and diatom record, AMS 14C chronology and sediment composition (loss-on-ignition and magnetic susceptibility data, provided information on vegetation history and palaeoenvironmental and palaeoclimatic changes since the time of the deglaciation of the area around 14 000 cal yr BP. The chronology of the sequence is based on seven AMS dates on terrestrial macrofossils, providing evidence of rapid sedimentation in between 14 000 and 13 500 cal yr BP. Loss-on-ignition data show a clear short-lived warming episode centred to 13 800 cal yr BP, tentatively correlated with the GI-1c warming of the event stratigraphy of the Last Termination in the North Atlantic region, which suggests that at least parts of the Haanja Heights were ice-free by 14 000 cal yr BP. Macrofossil evidence indicates Betula nana–Dryas octopetala-dominated open tundra communities with Saxifraga on dry ground, and Carex sp. and Juncus on wet ground at that time. The first evidence of the postglacial presence of tree birch (Betula pendula in Estonia is dated back to 13 500 cal yr BP. However, conifer remains were not found in the late glacial sediment sequence of Solova Bog. The late-Allerød (GI-1a organic deposits, which are quite typical of other parts of Estonia and indicate general warming, are missing at Solova, most probably due to a hiatus in sedimentation in this very small and shallow upland basin.

    The supported catalysts have received great attentions due to their high catalytic activity, low cost and good stability. Here we report the stability, wetting ability, corrosion resistance and catalytic activity of the supported catalysts with group 9, 10 and 11 metals (M = Co, Rh, Ir, Ni, Pd, Pt, Cu, Ag, Au) monolayers (ML) deposited on NbC(001), denoted as MML/NbC(001). The PdML/NbC(001) and PtML/NbC(001) are testified as the most stable and active ones with the former even better on the whole. The catalytic activities toward oxygen reduction reactions (ORR) are clarified by the dissociation and the change in Gibbs free energies for the elementary reaction steps of O2 on PdML/NbC(001).

    Both Alternating current (AC) conductivity and dielectric behavior of n-type organic thin films of N, N‧-Dimethyl-3,4,9,10-perylenedicarboximide (DMPDC) have been investigated. Fourier transformation infrared (FTIR) spectroscopy is used for identifying both powder and film bonds which confirm that there are no observed changes in the bonds between the DMPDC powder and evaporated films. The dependence of AC conductivity on the temperature for DMPDC evaporated films was explained by the correlated barrier hopping (CBH) model. The calculated barrier height using CBH model shows a decreasing behavior with increasing temperature. The mechanism of dielectric relaxation was interpreted on the basis of the modulus of the complex dielectric. The calculated activation energy of the relaxation process was found to be 0.055 eV.

    The formation of PTCDA (3,4,9,10-perylene-tetracarboxylic-dianhydride) nanostrutures on Au(1 1 1)-(22x√(3)) covered with NaCl islands has been studied using scanning tunneling microscopy (STM). Atomically resolved STM images show that NaCl grows as (1 0 0)-terminated layers on Au(1 1 1)-(22x√(3)). Local atomic hexagonal packing has also been observed in the NaCl(1 0 0) layer. At submonolayer NaCl coverage, PTCDA forms two-dimensional islands on the Au(1 1 1) surface and nucleate preferentially at the NaCl island step edges.

    The formation of PTCDA (3,4,9,10-perylene-tetracarboxylic-dianhydride) nanostrutures on Au(1 1 1)-(22x{radical}(3)) covered with NaCl islands has been studied using scanning tunneling microscopy (STM). Atomically resolved STM images show that NaCl grows as (1 0 0)-terminated layers on Au(1 1 1)-(22x{radical}(3)). Local atomic hexagonal packing has also been observed in the NaCl(1 0 0) layer. At submonolayer NaCl coverage, PTCDA forms two-dimensional islands on the Au(1 1 1) surface and nucleate preferentially at the NaCl island step edges. When the Au surface is fully covered with NaCl layers, PTCDA molecules form three-dimensional molecular clusters decorating the step edges of NaCl layers.

  2. Interactions between 9,10-anthraquinone and aromatic amines in homogeneous and micellar media: A laser flash photolysis and magnetic field effect study

    The interactions between 9,10-anthraquinone (AQ) and different aromatic amines, N,N-dimethylaniline and 4,4'-bis (dimethylamino) diphenylmethane (DMDPM), have been studied using absorption, steady-state fluorescence, and laser flash photolysis techniques in organic homogeneous and heterogeneous micellar media. In polar organic homogeneous medium, electron transfer (ET) occurs from amines to excited AQ. In micellar medium, similar intermolecular ET is observed. However, in latter medium, ET predominates over hydrogen abstraction from micelles by excited AQ itself. The occurrence of ET has been further supported by the application of an external magnetic field during laser flash photolysis experiments, which modulates the yield of radical ion pairs formed through ET. Another novel feature, which has also been discussed here, is the abnormal behavior of DMDPM in micellar medium pertaining to energy transfer

    The photophysical properties of 1,4-dihydroxy-2,3-dimethyl-9,10-anthroquinone (DHDMAQ) in the absence and presence of titanium dioxide (TiO2) nanoparticles have been studied using UV-visible absorption spectroscopy and steady-state fluorescence spectroscopy. The fluorescence intensity of the DHDMAQ decreases as the concentration of TiO2 nanoparticles increases. The quenching is characterized by a Stern-Volmer plot, which displays a positive deviation from linearity. This could be explained by static quenching models. The Stern-Volmer quenching constant, association constant, and binding constant have been calculated. The distance between DHDMAQ and TiO2 nanoparticles has also been evaluated using Forster's theory of non-radiative energy transfer.

    Tandem organic light emitting diodes (OLEDs) are ideal for lighting applications due to their low working current density at high brightness. In this work, we have studied an efficient electron transporting layer of KBH(4) doped 9,10-bis(3-(pyridin-3-yl)phenyl)anthracene (DPyPA) which is located adjacent to charge generation layer of MoO(3)/NPB. The excellent transporting property of the DPyPA:KBH(4) layer helps the tandem OLED to achieve a lower voltage than the tandem device with the widely used tris-(8-hydroxyquinoline)aluminum:Li. For the tandem white OLED with a fluorescent blue unit and a phosphorescent yellow unit, we've achieved a high current efficiency of 75 cd/A, which can be further improved to 120 cd/A by attaching a diffuser layer.

    Owning a pet dog could potentially improve child health through encouraging participation in physical activity, through dog walking. However, evidence to support this is limited and conflicting. In particular, little is known about children's participation in dog walking and factors that may be associated with this. The objective of this study was to describe the participation of children in dog walking, including their own and those belonging to somebody else, and investigate factors associated with regular walking with their own pet dog. Primary school children (n=1021, 9-10 years) from a deprived area of Liverpool were surveyed during a 'fitness fun day' as part of the SportsLinx project. The 'Child Lifestyle and Pets' survey included questions about pet ownership, pet attachment, and dog walking. Multivariable logistic regression models were used to investigate factors associated with walking any dog, or their own dog, several times a day or more, including level of attachment to the dog, dog type, and sociodemographic factors. Overall, 15.4% of children reported walking with any dog (their own or belonging to a friend or family member) ≥ once daily, 14.1% several times a week, 27.6% ≤ once a week, and 42.8% never. Dog owning children (37.1% of the population) more often reported dog walking 'several times a week or more' (OR=12.30, 95% CI=8.10-18.69, Ppet dogs may be an opportunity for increasing physical activity in 9-10 year old children. The identification of stronger attachment to dogs regularly walked is similar to findings in adult studies.

    Lipid-based ready-to-use foods are currently used for infant feeding, but their potential effect on breast-milk intake is not well documented. The objective was to assess the breast-milk intake of 9-10-mo-old infants given either a ready-to-use complementary food (RUCF) paste or a standard corn-soy blend (UNIMIX) porridge in South Kivu, Democratic Republic of Congo. Infants were randomly assigned at 6 mo of age to receive either RUCF (n = 700) or UNIMIX (n = 700) for 6 mo. Breast-milk intake was measured at 9-10 mo in a subsample of 58 infants (29 from each group). Mothers received a dose of ≈30 g deuterium oxide. Predose and postdose saliva samples were collected from both mothers and infants over 2 wk. Breast-milk intake (g/d) was measured from saliva samples by using infrared spectroscopy. Mean (±SD) breast-milk intake was not significantly (P = 0.69) different between the 2 groups: RUCF (705 ± 236 g/d) and UNIMIX (678 ± 285 g/d). Mean (±SD) nonmilk oral water intakes were 338.3 ± 251.1 and 336.4 ± 227.2 g/d for RUCF and UNIMIX, respectively (P = 0.98). No differences in breast-milk intake were observed between infants consuming either RUCF or UNIMIX. The deuterium-dose-to-the-mother dilution technique is an affordable technique that we recommend for periodic evaluation of breast-milk intake in resource-poor settings. This trial is registered at controlled-trials.com as ISRCTN20267635.

  7. Excited-state intramolecular hydrogen transfer (ESIHT) of 1,8-Dihydroxy-9,10-anthraquinone (DHAQ) characterized by ultrafast electronic and vibrational spectroscopy and computational modeling

    We combine ultrafast electronic and vibrational spectroscopy and computational modeling to investigate the photoinduced excited-state intramolecular hydrogen-transfer dynamics in 1,8-dihydroxy-9,10-anthraquinone (DHAQ) in tetrachloroethene, acetonitrile, dimethyl sulfoxide, and methanol. We analyze the electronic excited states of DHAQ with various possible hydrogen-bonding schemes and provide a general description of the electronic excited-state dynamics based on a systematic analysis of femtosecond UV/vis and UV/IR pump-probe spectroscopic data. Upon photoabsorption at 400 nm, the S 2 electronic excited state is initially populated, followed by a rapid equilibration within 150 fs through population transfer to the S 1 state where DHAQ exhibits ESIHT dynamics. In this equilibration process, the excited-state population is distributed between the 9,10-quinone (S2) and 1,10-quinone (S1) states while undergoing vibrational energy redistribution, vibrational cooling, and solvation dynamics on the 0.1-50 ps time scale. Transient UV/vis pump-probe data in methanol also suggest additional relaxation dynamics on the subnanosecond time scale, which we tentatively ascribe to hydrogen bond dynamics of DHAQ with the protic solvent, affecting the equilibrium population dynamics within the S2 and S1 electronic excited states. Ultimately, the two excited singlet states decay with a solvent-dependent time constant ranging from 139 to 210 ps. The concomitant electronic ground-state recovery is, however, only partial because a large fraction of the population relaxes to the first triplet state. From the similarity of the time scales involved, we conjecture that the solvent plays a crucial role in breaking the intramolecular hydrogen bond of DHAQ during the S2/S1 relaxation to either the ground or triplet state. © 2014 American Chemical Society.

    Full Text Available The aim of this article is to analyse how tween girls in Estonia and in Sweden describe and discover their gender identities when selecting profile images for social networking sites (SNSs. To this end, interviews with tweens in Estonia (N=21 and in Sweden (N=31 were carried out. As SNSs largely exist without the recognisable surveillance of adults, children can explore the social matrix of relating to others, and they also feel safe to try out and display different constructions and reconstructions of their identity. At the same time, in communicating online, impression management is formulated with constant worry about how to construct one’s virtual identity so that it will be appreciated and accepted by one’s peer group. In this article, our analysis focuses on the most popular posing strategies used by tween girls, which, it turns out, are often marked by reproduction of the dominant heterosexual cultural norms and values.

    To find out how experienced primary care physicians working in different societies see themselves as doctors. A cross-sectional study. Primary health care in Estonia and Finland. Estonian district doctors (n = 110) and Finnish specialists of general practice (n = 211). In a postal questionnaire the respondents were asked to evaluate how well 18 different expressions described them as doctors on a 5-step scale from "1 = very poorly" to "5 = very well". Four of the five expressions that were thought most accurate and telling--"Listener", "Vocational doctor", "Helper", and "Family physician"--were the same in Estonia and Finland. Even though there are differences in health care systems, the self-images of primary care doctors in both countries were more or less consistent with the international definitions of the general practitioner's job and role.

    Full Text Available Independent and interdependent self-construal values of three generations and the intergenerational similarity of self-construal was compared in three countries. The participants were 837 adolescents, their mothers (227 from Russia, 311 from Germany, and 299 from Estonia and 293 maternal grandmothers. In Germany, all three generations displayed higher scores on independence than participants from other countries. Russian participants had higher scores on interdependence compared to participants from other countries. Adolescents scored significantly higher on the interdependent self-construal than the two older generations, and higher than the mothers’ generation on the independent self-construal. Grandmothers’ self-construal was related to mothers’ in all three countries. In Germany and Estonia, mothers’ interdependent self-construal was related to adolescents’ interdependent self-construal. Grandmothers’ (but not mothers’ independent self-construal predicted adolescents’ independent self-construal. The results are discussed in light of the Family Change Theory and the different roles the participants have.

    Full Text Available The early Palaeozoic order Ascocerida is a group of morphologically unique and rare cephalopods known from the Ordovician and Silurian rocks of Avalonia, Baltica, Laurentia and Perunica. The limited Estonian record of Silurian ascocerids is complemented with a specimen from the Pähkla locality (Island of Saaremaa; Paadla Regional Stage, Ludlow Series representing the stratigraphically oldest known occurrence of ascocerids in the Silurian of Estonia. The strata that were formerly exposed in Pähkla are likely correlated to the Hemse Group of the Island of Gotland (Sweden having a remarkable record of ascocerids. The appearance of Silurian ascocerids in Estonia is confined to a time interval when the group had the highest species diversity and the widest geographic dispersion, reaching also outside Baltica for the first time.

    Full Text Available After joining the European Union in 2004, the post-communist countries have dramatically changed their structure of expenditure for medical services. The cause of this is legislative and ownership changes in the new economy. The study analyzed the expenditure on medical services in the European Union with a special focus on Poland, Latvia, Lithuania and Estonia. The European Union countries were divided into clusters using different methods, that is, Ward’s, Two Step and Centroid Clustering. In the paper, the structure and changes in health expenses were presented according to the types of expenditures over the years 2004-2015. Countries were assigned to clusters based on three variables: medical products, appliances and equipment, outpatient services and hospital services. Variables were considered as a percentage of household budget. In Lithuania, Latvia and Estonia, there is a clear increase in the outpatient services spending compared to the hospital services expenditure.

    BACKGROUND AND OBJECTIVE. A constant gap has appeared in infant mortality among the 3 Baltic States - Latvia, Estonia, and Lithuania - since the restoration of independence in 1991. The aim of the study was to compare infant mortality rates in all the 3 Baltic countries and examine some of the macro- and socioeconomic factors associated with infant mortality. MATERIAL AND METHODS. The data were obtained from international databases, such as World Health Organization and EUROSTAT, and the national statistical databases of the Baltic States. The time series data sets (1996-2010) were used in the regression and correlation analysis. RESULTS. In all the 3 Baltic States, a strong and significant correlation was found: Latvia (r=-0.81, P<0.01), Lithuania (r=-0.93, P<0.01), and Estonia (r=-0.91, P<0.01). There was also a correlation between infant mortality and healthcare expenditure in local currency per capita: Latvia (r=-0.81, P<0.01); Lithuania (r=-0.90, P<0.01) and Estonia (r=-0.88, P<0.01). In Latvia (r=0.87, P<0.01) and Estonia (r=0.70; P<0.01), a significant correlation between infant mortality and unemployment levels was observed from 1996 to 2008, whereas the statistical significance disappeared in the period from 1996 to 2010. In Lithuania, the relationship was not significant. CONCLUSIONS. Higher infant mortality rates and a less stable decreasing tendency in Latvia are apparently explained by less successful adaptation to a new political and economic situation and limited skills in adjusting the healthcare system to the reality of life.

    Groundwater abstracted from the Middle Devonian aquifer system is the main source of drinking water in South Estonia. High iron and manganese concentrations in groundwater are the greatest problems in this region. The total iron concentrations up to 16 mg L–1 are mainly caused by a high Fe2+ content in water, pointing to the dominance of reducing conditions in the aquifer system.

    2014-12-01

    Full Text Available The paper focuses on a comparative analysis of people’s attitudes towards immigrants’ role in several aspects of countries’ life depending on the individual’s socio-demographic and economic characteristics in Estonia and Russia. The empirical part of the paper relies on the European Social Survey (ESS fifth round database. The results of the study show that the Estonian people’s attitudes towards immigrants are, on the average, better in all aspects of the country’s life – economy, culture and the country as a living place, compared to the Russian one. Both economic and non-economic factors explain the observed variation of individuals’ opinions regarding the role of immigrants in a country’s life. Ethnic minorities, religious people and people with higher income are more tolerant to immigrants in both countries. Socio-demographic characteristics such as age, gender and education are valid determinants of people’s attitudes towards immigrants only in Estonia. Highly educated people have more positive attitudes towards immigrants compared to less educated people in Estonia but not in Russia. The results of the analysis therefore highlight the necessity to take different factors into account for the design of the migration and integration policies in the countries with ethnically diverse population.

    2016-12-01

    Full Text Available In this study, the deglaciation chronology of the Pandivere Upland is defined, and the late-glacial vegetation trends of north-eastern Estonia are summarised. The multi-proxy study includes accelerated mass spectrometry 14 C dating, plant macrofossil, magnetic susceptibility, loss-on-ignition and grain-size distribution data of the lacustrine sediment record from one previously unpublished study site (Kursi, and the study discusses the results in combination with five previously published study locations from the area. The results indicate that the deglaciation of the Pandivere Upland started at approximately 14 200 cal. yr BP and was completed by 13 800 cal. yr BP. The ice recession rate was approximately 180 m yr -1 . Based on these new radiocarbon dates, the Baltic Ice Lake stage A 1 submerged the northern and western ice-free areas of Estonia by ca. 13 800 cal. yr BP. The prevalent vegetation type in north-eastern Estonia during the late-glacial period was tundra with local variations in the dominant shrub species. The region remained treeless until the Holocene.

    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

    A series of novel 1-amino and 1,4-diamino-9,10-anthraquinones, substituted with different alkyl groups, were synthesized as the result of alkylation with amino substituents. All the obtained aminoanthraquinone derivatives were characterized by NMR, IR spectroscopy and mass spectrometry. The spectroscopic properties of these compounds were determined by using UV-Vis spectroscopy in acetonitrile, and in the mixture of acetonitrile and methanol at different pH ranges. The effects of various substituents present in the newly developed anthraquinone derivatives and their ability to form hydrogen bonds between the carbonyl oxygen atom of anthraquinone moiety and nitrogen atom of N-H group in 1-aminoanthraquinone (1-AAQ) and 1,4-diaminoanthraquinone (1,4-DAAQ) were studied. Additionally, the effects of hydrogen bond formation between O-H group in hydroxyethylamino substituent and the carbonyl oxygen atom of anthraquinone were investigated. The spectroscopic behavior of the studied derivatives strongly depended on the solvent-solute interactions and the nature of solvent. The values of pKa for the new anthraquinones were determined by the combined potentiometric and spectrophotometric titration methods. Copyright © 2013 Elsevier B.V. All rights reserved.

    The 1-[1-oxo-3-phenyl-(2-benzosulfonamide)-propyl amido] - anthracene-9,10-dione (BPAQ) an analogue of anthracenedione class of antibiotic has been synthesized. To characterize molecular functional groups FT-IR and FT-Raman spectrum were recorded and vibrational frequencies were assigned accordingly. The optimized geometrical parameters, vibrational assignments, chemical shifts and thermodynamic properties of title compound were computed by ab initio calculations at Density Functional Theory (DFT) method with 6-31G(d,p) as basis set. The calculated harmonic vibrational frequencies of molecule were then analysed in comparison to experimental FT-IR and Raman spectrum. Gauge independent atomic orbital (GIAO) method was used for determining, (1H) and carbon (13C) nuclear magnetic resonance (NMR) spectra of the molecule. Molecular parameters were calculated along with its periodic boundary conditions calculation (PBC) analysis supported by X-ray diffraction studies. The frontier molecular orbital (HOMO, LUMO) analysis describes charge distribution and stability of the molecule which concluded that nucleophilic substitution is more preferred and the mullikan charge analysis also confirmed the same. Further the title compound showed an inhibitory action at d(TCCCCC), an intermolecular i-motif sequence, hence molecular docking study suggested the inhibitory activity of the compound at these junction.

    Solvation characteristics of 1,4-dihydroxy-2,3-dimethyl-9,10-anthraquinone ( 1) in pure and binary solvent mixtures have been studied by UV-vis absorption spectroscopy and laser-induced fluorescence techniques. The binary solvent mixtures used as CCl 4 (tetrachloromethane)-DMF ( N, N-dimethylformamide), AN (acetonitrile)-DMSO (dimethylsulfoxide), CHCl 3 (chloroform)-DMSO, CHCl 3-MeOH (methanol), and MeOH-DMSO. The longest wavelength band of 1 has been studied in pure solvents as well as in binary solvent mixtures as a function of the bulk mole fraction. The Vis absorption band maxima show an unusual blue shift with increasing solvent polarity. The emission maxima of 1 show changes with varying the pure solvents and the composition in the case of binary solvent mixtures. Non-ideal solvation characteristics are observed in all binary solvent mixtures. It has been observed that the quantity [ ν-(Xν+Xν)] serves as a measure of the extent of preferential solvation, where ν˜ and X are the position of band maximum in wavenumbers (cm -1) and the bulk mole fraction values, respectively. The preferential solvation parameters local mole fraction ( X2L), solvation index ( δs2), and exchange constant ( k12) are evaluated.

    2013-12-01

    Full Text Available The Aussie Optimism: Positive Thinking Skills Program (AOPTP is a school-based prevention program aimed at addressing anxious and depressive symptoms in children aged 9-10 years. Nine-hundred and ten students from 22 Australian primary schools situated in low socio-economic areas were randomly assigned to either an intervention or control group, and assessed at a 30-month follow up. Those in the intervention group received the AOPTP program, where the control group continued to receive the regular health education course. Students completed self-report measures regarding their levels of depression, anxiety, and attribution style. Parents also reported on their children’s externalising and internalising problems outside of school. There were no significant differences between groups in regard to anxiety or depression, as well as no significant differences in attributional styles. Parents reported significantly less hyperactive behaviours from children in the intervention group. This finding suggests that AOP-PTS has the capacity to treat externalising problems at a medium term effect. The decrease in the externalising problems provides evidence of a partial medium term intervention effect. Future studies should continue to evaluate the program at a long term follow up.

The aim of the workshop was to develop an international network of investigators engaged in HPV modeling and to facilitate open discussion about the structure and parameterization of models, as well as other methodologic concerns. Thirty-four participants from more than a dozen countries and a variety of settings, representing the authors or coauthors of 82% of the HPV modeling literature, exchanged ideas on fundamental questions in the field. These proceedings, based on the 217-page transcript, were assembled by the Scientific Committee to summarize the ideas of workshop participants in a deidentified, readable fashion. They represent the work and recorded opinions of session participants and do not constitute the official positions of participants as a whole or individually, the Scientific Committee, or any sponsoring organization or entity. In charting a path forward, 3 topics emerged as most pressing: best practices for HPV modeling, comparative modeling, and modeling in developing countries. This summary of the proceedings of the preconference workshop on HPV modeling characterizes many of the prominent contemporary issues in the field. 2010 Excerpta Medica Inc. All rights reserved.

    The electrochemiluminescence (ECL) properties of polycyclic aromatic hydrocarbons (PAHs) are excellent on account of the high photoluminescence quantum yield. However, the poor solubility and radical instability of PAHs in the aqueous solution severely restricted further biological application. Here 9,10-diphenylanthracene (DPA) nanoblocks (NBs) with good dispersibility and stability in aqueous solution were prepared according to morphology-controlled technology employing water-soluble polymers as a protectant. Furthermore, an ECL "off-on" switch biosensor was developed based on a novel ECL ternary system with DPA NBs as luminophore, dissolved O 2 as coreactant, and Pt-Ag alloy nanoflowers as the coreaction accelerator, which achieved a high-intense initial ECL signal. Subsequently, the Fc-DNA as ECL signal quencher was assembled on the electrode surface to quench the initial ECL signal for a "signal-off" state. Meanwhile, DNA swing arm was modified on the electrode surface for one-step DNA walker amplification. Interestingly, in the presence of miRNA-141 and T7 Exo, the one-step DNA walker amplification was executed to recover a strong ECL signal as a "signal-on" state by the digestion of Fc-DNA. Thus the developed ECL "off-on" switch biosensor possesses a detection limit down to 29.5 aM for ultrasensitive detection of miRNA-141, which is expected to be applicable to the detection of miRNA in clinic tumor cells.

    Full Text Available Some specific antibodies indicate the presence of antigenic structures on DNA (DNA adducts that can play an important role in the process of mutagenesis and/or carcinogenesis. They indicate the presence of increased genotoxic potential (hazard prior to the formation of disease (primary prevention. The present study was focused on the serum level of benzo[a]pyrene 7,8-diol-9,10-epoxide-DNA adducts antibodies (anti-BPDE-DNA in psoriatic patients (n=55 dermally exposed to different levels of polycyclic aromatic hydrocarbons (PAHs. The general goal of the study was to contribute to better understanding of the value of the assumed biomarker (anti-BPDE-DNA for evaluation of the organism's answer to genotoxic exposure to PAHs. Elevated level of exposure to PAHs resulted in the increased level of anti-BPDE-DNA. However, almost all levels of anti-BPDE-DNA ranged within the field of low values. Both variants of GT (CCT-3% and CCT-5% induced higher expression of anti-BPDE-DNA in the group of nonsmokers. Significant relations between the level of anti-BPDE-DNA and PASI score, total duration of the therapy, or time of UVR exposure were not found. Further studies are needed to reduce interpretation uncertainty of this promising bioindicator.

    In this study, a solution-processed n-type photo-sensing organic thin film transistor was investigated using polymeric dielectric under different white light illuminations. N, N′-di (2-ethylhexyl)-3,4,9,10-perylene diimide and divinyl tetramethyl disiloxane-bis (benzo-cyclobutene) were used as a soluble active organic semiconductor and as a dielectric material, respectively. Stable amplification was observed in the visible region without gate bias by the device. The electrical characterization results showed that an n-type phototransistor with a saturated electron mobility of 0.6 × 10{sup −3} cm{sup 2}/V·s and a threshold voltage of 1.8 V was obtained. The charge carrier density of the channel of the device exhibited photo-induced behaviors that strongly affected the electrical properties of the transistor. The photosensitivity and photoresponsivity values of the device were 63.82 and 24 mA/W, respectively. These findings indicate that perylene diimide is a promising material for use on organic based phototransistors. - Highlights: • A solution processed n-type organic phototransistor was fabricated. • The geometry of device allows to be used double sided photo-sensor to detect light. • The accumulation of charge carrier is effected strongly by illumination intensity. • The current amplification was observed clearly under illumination without gate bias.

  9. Inhibition of HIV-1 reverse transcriptase-catalyzed synthesis by intercalated DNA Benzo[a]Pyrene 7,8-Dihydrodiol-9,10-Epoxide adducts.

    Full Text Available To aid in the characterization of the relationship of structure and function for human immunodeficiency virus type-1 reverse transcriptase (HIV-1 RT, this investigation utilized DNAs containing benzo[a]pyrene-7,8-dihydrodiol-9,10-epoxide (BPDE-modified primers and templates as a probe of the architecture of this complex. BPDE lesions that differed in their stereochemistry around the C10 position were covalently linked to N (6-adenine and positioned in either the primer or template strand of a duplex template-primer. HIV-1 RT exhibited a stereoisomer-specific and strand-specific difference in replication when the BPDE-lesion was placed in the template versus the primer strand. When the C10 R-BPDE adduct was positioned in the primer strand in duplex DNA, 5 nucleotides from the 3΄ end of the primer terminus, HIV-1 RT could not fully replicate the template, producing truncated products; this block to further synthesis did not affect rates of dissociation or DNA binding affinity. Additionally, when the adducts were in the same relative position, but located in the template strand, similar truncated products were observed with both the C10 R and C10 S BPDE adducts. These data suggest that the presence of covalently-linked intercalative DNA adducts distant from the active site can lead to termination of DNA synthesis catalyzed by HIV-1 RT.

    We have studied the element and orbital-specific electronic structure of thin films of 3,4,9,10-perylene-tetracarboxylic-dianhydride (PTCDA) using a combination of synchrotron radiation-exited resonant x-ray emission spectroscopy, x-ray absorption spectroscopy, x-ray photoelectron spectroscopy, as well as density functional theory calculations. Resonant and non-resonant x-ray emission spectroscopies were used to measure the C and O 2p partial densities of state in PTCDA. Furthermore, resonant x-ray emission at the C and O K-edges is shown to be able to measure the partial densities of states associated with individual atomic sites. The flat molecular orientation of PTCDA on various substrates is explained in terms of the carbonyl O atom acting as a hydrogen-bond acceptor leading to multiple in-plane intermolecular C=O···H−C hydrogen bonding between carbonyl groups and the perylene core of the neighboring PTCDA molecules. We support this conclusion by comparison of our calculations to measurements of the electronic structure using element-, site-, and orbital-selective C and O K-edge resonant x-ray emission spectroscopy, and photoemission spectroscopy.

    The creep behaviour of NiCr20Co12Mo is investigated under static strain and at 800deg C, with stresses applied ranging from 105 MPa to 370 MPa. The ferritic steel 10CrMo 9 10 is tested for its creep behaviour under static strain and at the temperatures of 600deg C and 550deg C, with stresses applied between 154 MPa and 326 MPa (at 600deg C), or between 250 MPa and 458 MPa (at 550deg C). The experiments are made to determine the effects of changes in strain on the materials' deformation behaviour, placing emphasis on transient creep and elastic or anelastic response. The mean internal stress is determined from changes in strain. Cyclic creep is analysed as a behaviour directly responding to the pattern of change in strain. Effects of certain strain changes not clarified so far are analysed. The cyclic strain experiments are analysed according to the velocity factor concept. The usual models of creep deformation (theta projection concept) are compared with the model of effective strain, which is based on the fundamental equation of plastic deformation by dislocation motion (Orowan equation).

    The autophagy of human prostate cancer cells (PC3 cells) induced by a new anthraquinone derivative, 1-Hydroxy-3-[(E)-4-(piperazine-diium)but-2-enyloxy]-9,10-anthraquinone ditrifluoroactate (PA) was investigated, and the relationship between autophagy and reactive oxygen species (ROS) generation was studied. The results indicated that PA induced PC3 cell death in a time- and dose-dependent manner, could inhibit PC3 cell growth by G1 phase cell cycle arrest and corresponding decrease in the G2/M cell population and induced S-phase arrest accompanied by a significant decrease G2/M and G1 phase numbers after PC3 cells treated with PA for 48 h, and increased the accumulation of autophagolysosomes and microtubule-associated protein LC3-ll, a marker of autophagy. However, these phenomenon were not observed in the group pretreated with the autophagy inhibitor 3-MA or Bafilomycin A1 (BAF), suggesting that PA induced PC3 cell autophagy. In addition, we found that PA triggered ROS generation in cells, while the levels of ROS decreased in the N-acetylcysteine (NAC) co-treatment, indicating that PA-mediated autophagy was partly blocked by NAC. In summary, the autophagic cell death of human PC3 cells mediated by PA-triggered ROS generation. Copyright © 2017 Elsevier B.V. All rights reserved.

    The interaction of a perylene derivative namely N,N-bis(2,5-di-tert-butylphenyl)-3,4:9,10-perylenebis(dicarboximide) (DBPI) with colloidal silver nanoparticles (AgNPs) was studied in ethanol and ethylene glycol using steady state fluorescence quenching measurements. The Stern–Volmer quenching rate constant (K{sub sv}) was calculated as 4.03×10{sup 9} and 29.14×10{sup 9} M{sup −1} in ethanol and ethylene glycol, respectively. From fluorescence quenching data, static quenching and energy transfer play a major role in the fluorescence quenching of DBPI by AgNPs. The apparent association constant (k{sub app}) was calculated as 1.26×10{sup 8} M{sup −1} in EtOH and 1.83×10{sup 9} M{sup −1} in ethylene glycol. Due to potential AgNPs interaction with DBPI, the average AgNPs size is increased slightly from ∼37.1 nm (As-prepared) to 48.9 nm. -- Highlights: • Fluorescence quenching of photostable DBPI by AgNPs. • Static quenching mechanism of interaction between DBPI and AgNPs. • Enhancement of fluorescence quenching of DBPI in ethylene glycol.

    Silver nanoparticles (Ag NPs) of various sizes have been successfully synthesized by the simple and convenient Creighton method using sodium borohydride as the reducing agent under microwave irradiation. Optical absorption and fluorescence emission spectroscopic techniques were employed to investigate the effect of silver nanoparticles on the ground and excited state of 1,4-dimethoxy-3-methylanthracene-9,10-dione (DMMAD). The surface plasmon resonance (SPR) peak of the prepared silver colloidal solution was observed at 400 nm. Fluorescence quenching of DMMAD by silver nanoparticles has been found to increase with increase in the size of Ag. The fluorescence quenching has been explained by Forster Resonance Energy Transfer (FRET) theory between DMMAD and silver nanoparticles. The Stern–Volmer quenching constant and Benesi–Hildebrand association constant for the above system were calculated. DFT calculations were also performed to study the charge distribution of DMMAD in Ag both in ground and excited states. -- Highlights: • Silver nanoparticles (Ag NPs) have been synthesized using the Creighton method. • Effect of Ag NPs on the ground state of DMMAD was studied. • Influence of Ag NPs on the excited state of DMMAD was investigated. • Fluorescence quenching has been explained by Forster Resonance Energy Transfer. • Quenching and binding constants were also calculated.

    In order to elucidate the function of the targeting protein for Xenopus kinesin-like protein 2 (Xklp2) (TPX2) in the malignant transformation of human bronchial epithelial cells induced by anti-benzo[a]pyrene-trans-7, 8-dihydrodiol-9, 10-epoxide (anti-BPDE), TPX2 was characterized in cells at both the gene and the protein levels. TPX2 was present at higher levels in 16HBE-C cells than in 16HBE cells as demonstrated by two-dimensional gel electrophoresis, immunocytochemistry, Western blot analysis and RT-PCR. TPX2 was also detected in lung squamous-cell carcinoma tissues by immunohistochemistry, but not in normal lung tissues. Depression of TPX2 by RNA interference in 16HBE-C cells led to a decrease in cell proliferation, S-phase cell cycle arrest and cell apoptosis. Abnormal TPX2 tyrosine phosphorylation was detected in 16HBE-C cells, and this could be inhibited, to different degrees, by tyrosine kinase inhibitors. Inhibiting tyrosine phosphorylation in 16HBE-C cells by three selected tyrosine protein kinase inhibitors, tyrphostin 47, AG112 and AG555, caused G 0 /G 1 -phase cell cycle arrest. Our results suggest that anti-BPDE can cause the over-expression of TPX2 and its aberrant tyrosine phosphorylation. Misregulation of TPX2 affects the cell cycle state, proliferation rates and apoptosis

    To examine the differences in dietary intakes of children consuming school meals and packed lunches, the contribution of lunchtime intake to overall dietary intake, and how lunchtime intake relates to current food-based recommendations for school meals. Cross-sectional analysis of overall intake of macronutrients and food choice from 4 d food diaries and school lunchtime intake from the two diary days completed while at school. Norfolk, UK. One thousand six hundred and twenty-six children (aged 9-10 years) attending ninety Norfolk primary schools. At school, lunchtime school meal eaters consumed more vegetables, sweet snacks, chips, starchy foods and milk, and less squash/cordial, fruit, bread, confectionery and savoury snacks than packed lunch eaters. These differences were also reflected in the overall diet. On average school meal eaters met the School Food Trust (SFT) food-based standards, while food choices among packed lunch eaters were less healthy. The contribution of food consumed at school lunchtime to overall diet varied by food and lunch type, ranging from 0.8 % (milk intake in packed lunches) to 74.4 % (savoury snack intake in packed lunches). There were significant differences in the foods consumed by school meal and packed lunch eaters, with food choices among school meal eaters generally in line with SFT standards. The food choices made at school lunchtime make a significant contribution to overall diet.

  17. THE BOOK PUBLISHING SYSTEM IN ESTONIA DURING THE SOVIET RULE IN 1944–1991

    Full Text Available The article treats the changes in the direction of the publishing activities, the formation of the network of the state book publishing houses as well as the political and economic conditions of their activities in Estonia during the second Soviet occupation in 1944–1991. These years have been divided in three periods according to political history: the Stalinist era in 1944–1956; the thawand stagnation in 1956–1986 and the political break-through leading to the restoration of independence in 1987–1991.Special attention is paid to the leading role of the Communist Party of the USSR and the Communist Party of the ESSR in publishing activities. For example, only the all-union communist party had a right to decide over the establishment of new publishing houses, the leading officials of the local and all-union communist party studied and confirmed the reports and plans of the publishers etc. For the implementation of the regulations of the communist party a specialadministrative body was established, operating under different names in different years. For example, during the all-union reform of 1949 it was called the Central Board of Printing Industry, Publishing and Book Trade by the Council of Ministers, after the reform of 1963 – the State Publishing Committee. The latter had especially wide authority and gave detailed instructions on organising the work in the publishing houses. The directions included rigid requirements about the planning process and co-ordination of the plans on local and all-union level. The co-ordination of plans became especially complex since 1975 when the publishing houses had to get consent fromthe Head Office of Thematic Planning and Co-ordination of the all-union State Publishing Committee for every manuscript they wished to include in their plans. Although this system was unable to function, it was not revoked. All this demonstrates the dependence of the Estonian publishing from the all-union directions and

    Full text: In November 2002 first 18F-FDG-PET was performed in Estonia using a mobile truck-mounted scanning technology (Accel, Siemens) provided by the International Healthcare Group (IHG, Amersfoort, Netherlands). The FDG was provided by MAP Medical Technologies, Schering, (Helsinki, Finland). In 2003 this scheme was repeated for further scanning sessions. Evaluation of cutaneous malignant melanoma (CMM) using nuclear technique is of particular interest in Estonia as its incidence is on the rise. F-18 fluorodeoxyglucose positron emission tomography (FDG-PET) in CMM has a well-documented high diagnostic accuracy, especially in staging of the disease. The aim of the current study was to assess the impact of 18F-FDG-PET on detailed staging and clinical management in CMM. 30 patients of CMM, 16 males and 14 females, all non-diabetic, in the age range of 26 to 69 years were studied. Of these 30 patients, 12 were of high risk primary CMM, 7 had regional lymph node metastases and 11 had distant metastases. Patients were asked to consume a low-carbohydrate diet 3 days prior to the FDG-PET scan. 194 to 410 MBq (average 335 MBq) 18F-FDG was administered to the patients who were asked to come fasting for a minimum of 6 hours. Whole body scan was performed 40 to 65 minutes after the administration of FDG on the mobile PET. In 13 of the 30 patients (43%) 18F-FDG-PET changed the staging. In remaining 17 patients (57%) 18F-FDG-PET increased confidence level for the chosen treatment. Lymphadenectomy was planned in 2 patients showing lymph node involvement on FDG-PET. In other 2 patients, one with small pulmonary and other with a liver lesions found on PET but negative on radiological examination 'wait-and-watch' strategy was chosen. An unexpected hypermetabolic lesion seen in 1 case turned out to be a benign focus of connective tissue. One patient shown to have multiple distant metastases was started on chemotherapy. Finally in 8 of the 30 (27%) patients an immediate positive

    The environmental impacts of strawberries have been assessed in several studies. However, these studies either present dissimilar results or only focus on single impact categories without offering a comprehensive overview of environmental impacts. We applied the product environmental footprint (PEF) methodology to broadly indicate the environmental impacts of various strawberry production systems in Germany and Estonia by 15 impact categories. Data for the 7 case studies were gathered from two farms with organic and two farms with conventional open field production systems in Estonia and from one farm with conventional open field and one farm with a polytunnel and greenhouse production system in Germany. The greenhouse production system had the highest environmental impact with a PEF of 0.0040. In the field organic production systems, the PEF was 0.0029 and 0.0028. The field conventional production systems resulted in a PEF of 0.0008, 0.0009 and 0.0002. Polytunnel PEF was 0.0006. Human toxicity cancer effects, particulate matter and human toxicity non-cancer effects resulted in the highest impact across all analysed production systems. The main contributors were electricity for cooling, heating the greenhouse and the use of agricultural machinery including fuel burning. While production stage contributed 85% of the total impact in the greenhouse, also other life cycle stages were important contributors: pre-chain resulted in 71% and 90% of impact in conventional and polytunnels, respectively, and cooling was 47% in one organic system. Environmental impact from strawberry cooling can be reduced by more efficient use of the cooling room, increasing the strawberry yield or switching from oil shale electricity to other energy sources. Greenhouse heating is the overall impact hotspot even if it based on renewable resources. A ranking of production systems based on the environmental impact is possible only if all relevant impacts are included. Future studies should aim

    The main deficiencies of the district heating system in Kohtla-Jaerve, Ahtme and Johvi (Estonia) were identified as being: Inefficiency of the heat and power production plants; Lack of means for the consumers to control their consumption of energy due to the existing constant flow system; The environmental impact from heat and power production based on oil shale; Water and heat losses from the network; Low heat intensity in the Johvi area. Investigations indicate that improvement should have first priority at the Kohtla-Jaerve power plant, total investment is estimated at US D 60,3 million, of which US D 48 million are foreign costs. The cash flow will be negative in the first half of the projects lifetime. Estii Energia should be involved in the financing of the project. At the present price level, introduction of variable flow does not significantly improve the financial viability of the project, and the improvement of the district heating system might be carried out at a later stage, when the tariff has found a more stable level and the financial viability will be more significant. Implementation of new boilers in the Kohtla-Jaerve power plant. Circulating Fluidized Bed boilers, as well as electrostatic filters and estimated to reduce the environmental impact considerably. A more in depth study of the environmental impact from utilisation of oil shale should be carried out, also in order to inform possible investors of risk of investing in the oil shale industry. It will be more expensive to supply Johvi as an independent district heating system than if Johvi is supplied from Ahtme. The results arrived at are based on a range of the crucial assumptions that: the price of oil shale is expected to reach 75% of the price of coal, the sales price of electricity from plants is 62% of the consumer price, the exchange rate of the Estonian currency is kept constant to the DEM and that the inflation is Estonia will decline from 21% to 2,3% in 2005.

    Full Text Available To elucidate the exciton dynamics at the heteromolecular interface, the temperature dependence of time-resolved photoluminescence (TRPL spectra of neat-N,N′-dioctyl-3,4,9,10-perylenedicarboximide (PTCDI-C8 and PTCDI-C8/Quaterrylene (QT heteromolecular thin films was investigated. The lifetimes of excitons were evaluated to identify the Frenkel (FE, high energy charge-transfer (CTEhigh, low energy charge-transfer (CTElow, and excimer exciton states. The thermal activation energy (Δact of CTElow in PTCDI-C8 thin film was evaluated as 25 meV, which is 1/5 of that of FE, indicating that CTElow is more thermally sensitive than FE in PTCDI-C8 thin film. We investigated the exciton transport length (l along the vertical direction against the substrate surface in PTCDI-C8/QT thin film at 30 K, and demonstrated that lFE = 9.9 nm, lCTElow = 4.2 nm, lCTEhigh = 4.3 nm, and lexcimer = 11.9 nm. To elucidate the difference in l among these excitons, the activation energies (Ea for quenching at the heteromolecular interface were investigated. Ea values were estimated to be 13.1 meV for CTElow and 18.6 meV for CTEhigh. These values agree with the thermal sensitivity of CTEs as reported in a previous static PL study. This latter situation is different from the case of FE and excimer excitons, which are transported via a resonant process and have no temperature dependence. The small Ea values of CTEs suggest that exciton transport takes place via a thermal hopping process in CTEs. The present experimental study provides information on nano-scaled exciton dynamics in a well-defined PTCDI-C8 (2 ML/QT (2 ML system.

    The present study aimed to evaluate the efficacy of krypton laser photodynamic therapy (PDT) with PsD-007 for the treatment of oral mucosa dysplasia in 9,10-dimethyl-1,2-benzanthracene (DMBA)-treated hamsters. A DMBA-induced hamster cheek pouch model of precancerous lesions was created and the resultant 25 hamsters were divided into five groups. The right side was treated with PDT and the left side was used as the positive control. Following systemic anesthesia, an incision was made in the groin area to expose the femoral vein. PsD-007 was administered intravenously through the femoral vein. Various doses of photosensitizer were used to treat groups A-E. Subsequent to closing the incision, the right side of the buccal mucosa was irradiated with light using the krypton laser at a wavelength of 413 nm, a power density of 150 mW/cm 2 and an irradiation time of 20 min. At six weeks post-surgery, the response was analyzed using histological examinations of the buccal pouch mucosa. A total of 24 hamsters completed the six-week observation period, as one hamster from group C died in the second week following the PDT. Of all 24 irradiated sides, 15 formed normal mucosal tissues and nine demonstrated mild dysplasia. Of the total control sides, six developed moderate dysplasia, five developed severe dysplasia and 13 progressed to carcinoma in situ or squamous cell carcinoma (SCC). The results revealed a significant difference between the two sides (P10 mg/kg, there was no statistical difference (P>0.05). PsD-007-mediated krypton laser PDT is effective for the treatment of oral mucosa dysplasia in hamsters.

    Time-resolved electron spin resonance has been used to study quenching reactions between the antioxidant Vitamin C (VC) and the triplet excited states of 9,10-phenanthrenequinone (PAQ) in ethylene glycol-water (EG-H2O) homogeneous and inhomogeneous reversed micelle solutions. Reversed micelle solutions were used to be the models of physiological environment of biological cell and tissue. In PAQ/EG-H2O homogeneous solution, the excited triplet of PAQ (3PAQ*) abstracts hydrogen atom from solvent EG. In PAQ/VC/EG-H2O solution, 3PAQ* abstracts hydrogen atom not only from solvent EG but also from VC. The quenching rate constant of 3PAQ* by VC is close to the diffusion-controlled value of 1.41 × 108 L/(mol ·s). In hexadecyltrimethylammonium bromide (CTAB)/EG-H2O and aerosol OT (AOT)/EG-H2O reversed micelle solutions, 3PAQ* and VC react around the water-oil interface of the reversed micelle. Exit of 3PAQ* from the lipid phase slows down the quenching reaction. For Triton X-100 (TX-100)/EG-H2O reversed micelle solution, PAQ and VC coexist inside the hydrophilic polyethylene glycol core, and the quenching rate constant of 3PAQ* by VC is larger than those in AOT/EG-H2O and CTAB/EG-H2O reversed micelle solutions, even a little larger than that in EG-H2O homogeneous solution. The strong emissive chemically induced dynamic electron polarization of As.- resulted from the effective TM spin polarization transfer in hydrogen abstraction of 3PAQ* from VC.

    Full Text Available Community empowerment approaches have been proven to be powerful tools for solving local health problems. However, the methods for measuring empowerment in the community remain unclear and open to dispute. This study aims to describe how a context-specific community empowerment measurement tool was developed and changes made to three health promotion programs in Rapla, Estonia. An empowerment expansion model was compiled and applied to three existing programs: Safe Community, Drug/HIV Prevention and Elderly Quality of Life. The consensus workshop method was used to create the measurement tool and collect data on the Organizational Domains of Community Empowerment (ODCE. The study demonstrated considerable increases in the ODCE among the community workgroup, which was initiated by community members and the municipality’s decision-makers. The increase was within the workgroup, which had strong political and financial support on a national level but was not the community’s priority. The program was initiated and implemented by the local community members, and continuous development still occurred, though at a reduced pace. The use of the empowerment expansion model has proven to be an applicable, relevant, simple and inexpensive tool for the evaluation of community empowerment.

    The most common ventilation system in residential buildings in Ukraine is natural ventilation. In recent years, due to increased tightness of structures, an increase in the content of synthetic finishing materials in them, the quality of microclimate parameters deteriorated. One of the measures to improve the parameters of indoor air in residential buildings is the use of mechanical inflow and exhaust ventilation system. In this article the regulatory documents concerning the design of ventilation systems in Ukraine and Estonia and the requirements for air exchange in residential buildings are considered. It is established that the existing normative documents in Ukraine are analogous to European norms, which allow design the system of ventilation of residential buildings according to European standards. However, the basis for the design of ventilation systems in Ukraine is the national standards, in which mechanical ventilation, unfortunately, is provided only for the design of high-rise buildings. To maintain acceptable microclimate parameters in residential buildings, it is advisable for designers to apply the requirements for designing ventilation systems in accordance with European standards.

    This paper attempts to explore the migration patterns during the transition period in Estonia. A structuration approach was used to analyze data from the Estonian Statistical Office collected in 1997. Findings show that for migration between urban and rural areas, work-related reasons have been the most important motivating factor in urban growth during the transition period. Also considered are the family and education. In relation to sociodemographic structure of the population, men cite work, while women count family-related reasons, as the main motive for migrating. As to nonregistration, the most significant reason relates to issues of ownership. Because migrants are living in rented housing, it is not possible for them to register even if they desire to do so. Other reasons include "temporary", associated with study and work; "juridical", bureaucratic matters; and "multiple places of residence". This analysis, however, is incomplete because the attitudes and patterns of behavior have only partially or perfunctorily been related to the dramatic changes that have occurred in Estonian society. Proper statistical data are needed to help examine trends at a more disaggregated spatial level.

    Increasing human activity continues to threaten peatlands, and as the area of natural mires declines, our obligation is to restore their ecosystem functions. Several restoration strategies have been developed for restoration of extracted peatlands, including "The moss layer transfer method", which was initiated on the Tässi extracted peatland in central Estonia in May 2012. Three-year study shows that despite the fluctuating water table, rainfall events can compensate for the insufficient moisture for mosses. Total plant cover on the restoration area attained 70 %, of which ~60 % is comprised of target species-Sphagnum mosses. From restoration treatments, spreading of plant fragments had a significant positive effect on the cover of bryophyte and vascular plants. Higher water table combined with higher plant fragments spreading density and stripping of oxidised peat layer affected positively the cover of targeted Sphagnum species. The species composition in the restoration area became similar to that in the donor site in a natural bog. Based on results, it was concluded that the method approved for restoration in North America gives good results also in the restoration of extracted peatland towards re-establishment of bog vegetation under northern European conditions.

    To assess, at a clinical level, the mental health of former Chernobyl cleanup workers from Estonia by comparing them with same-age controls. The Mini International Neuropsychiatric Interview (MINI) was administered during 2011-2012 to 99 cleanup workers and 100 population-based controls previously screened for mental health symptoms. Logistic regression analysis showed that cleanup workers had higher odds of current depressive disorder (odds ratio [OR] = 3.07, 95% confidence interval [CI: 1.34, 7.01]), alcohol dependence (OR = 3.47, 95% CI [1.29, 9.34]), and suicide ideation (OR = 3.44, 95% CI [1.28, 9.21]) than did controls. Except for suicide ideation, associations with Chernobyl exposure became statistically nonsignificant when adjusted for education and ethnicity. A quarter of a century after the Chernobyl accident, Estonian cleanup workers were still at increased risk of mental disorders, which was partly attributable to sociodemographic factors.

    Wood-pastures are associated with high cultural and biodiversity values in Europe. However, due to their relatively low productivity, large areas of wood-pastures have been lost over the last century. In some areas, incentive schemes have been developed to revive wood-pastures. We investigated the effects of one such scheme in western Estonia. We compared the structure of grazed wood-pastures (old and restored) to those of abandoned wood-pastures and ungrazed forest stands to explore the effects of management, and conducted interviews with 24 farmers to investigate their motivations to carry out the management. We found a positive influence of active management on the semi-open structure of wood-pastures. Financial support was vital for management, but personal values related to tradition also played an important role. The interviewees differed widely in their range of motivations, suggesting that other strategies in addition to financial incentives would further improve the management of wood-pastures in the region.

  11. Geological settings of the protected Selisoo mire (northeastern Estonia threatened by oil shale mining

    Full Text Available The protected Selisoo mire in northeastern Estonia is located above valuable oil shale resources, partly in the permitted mining area. We describe in detail the geomorphology and geological setting of the mire to understand the natural preconditions for its formation, development and preservation. We used the LiDAR-based digital elevation model for relief analysis, mapped the peat thickness with ground-penetrating radar and described the Quaternary cover through corings. Ridges, oriented perpendicular to the generally southward-sloping terrain, and shallow depressions at the surface of mineral soil have influenced mire formation and its spatio-temporal dynamics. The Quaternary cover under the mire is thin and highly variable. Therefore the mire is hydro­geologically insufficiently isolated from the limestone bedrock that is drained by the nearby oil shale mine and consequently the mining activities approaching the mire may have a negative influence on the wetland and proposed Natura 2000 site. Natura 2000 type wetlands, both protected or currently outside the nature reserves, cover a significant portion of the prospective oil shale mining areas. The distribution and resilience of those sites may significantly influence further utilization of oil shale resources.

    Full Text Available For the first time a telephinid trilobite was recorded from the shallow-water rocks of the North Estonian Confacies Belt in the oil-shale mining area of northeast Estonia. A cranidium of Telephina (Telephops biseriata (Asklund was collected from a loose boulder of the kerogenous limestone of the Viivikonna Formation, Kukruse Stage, together with a rich assemblage of other trilobites, bryozoans, ostracods and rare graptolites. In its type area Jämtland, Sweden, T. biseriata occurs together with Pygodus anserinus and Hustedograptus teretiusculus in the Ståltorp Limestone Member of the Andersö Shale Formation, marking the latest Darriwilian. The occurrence in the North Estonian Confacies Belt of Telephina, known as a pelagic trilobite inhabiting deeper-water areas, probably reflects a transgression event at this time. Together with T. biseriata, other trilobite taxa such as Remopleurides and Lonchodomas, common in the Hustedograptus teretiusculus Biozone in deeper-water areas, arrive in the North Estonian Confacies Belt. Graptolites from the other loose boulders at the same locality have been identified as Hustedograptus cf. uplandicus, which occur together with a few dendroids.

    The main objective of the project has been to assist Kaerdla Municipality with the rehabilitation of their district heating system with Danish technology, and thereby support and make it possible for the Municipality of Kaerdla to develop the district heating sector in Kaerdla and thereby also to reduce emissions of harmful gases to the environment, as well as making a much more rational and energy efficient system. The project would further on demonstrate the use of pre-insulated pipes, which are fully sealed against penetration of water as well as demonstrate the use of compact units as substations including weather compensation control systems for regulation of heat and hot tap water supply for the district heating consumers. Besides the project gives significantly decreases in energy consumption`s and in the pollution from the production of energy, the objective of the project was also to put great stress on providing technical assistance to Kaerdla DH company, in order to make them capable in operation and maintenance of the new district heating system, and also to train the local operational staff in operation of the complete district heating system. The project will have a high demonstration value towards other towns in Estonia with similar problems and configurations of their heating systems. (EG)

    Arbuscular mycorrhizal (AM) fungal communities vary across habitat types, as well as across different land use types. Most relevant research, however, has focused on agricultural or other severely human-impacted ecosystems. Here, we compared AM fungal communities across six habitat types: calcareous grassland, overgrown ungrazed calcareous grassland, wooded meadow, farmyard lawn, boreonemoral forest, and boreonemoral forest clear-cut, exhibiting contrasting modes of land use. AM fungi in the roots of a single host plant species, Prunella vulgaris, and in its rhizosphere soil were identified using 454-sequencing from a total of 103 samples from 12 sites in Estonia. Mean AM fungal taxon richness per sample did not differ among habitats. AM fungal community composition, however, was significantly different among habitat types. Both abandonment and land use intensification (clearcutting; trampling combined with frequent mowing) changed AM fungal community composition. The AM fungal communities in different habitat types were most similar in the roots of the single host plant species and most distinct in soil samples, suggesting a non-random pattern in host-fungal taxon interactions. The results show that AM fungal taxon composition is driven by habitat type and land use intensity, while the plant host may act as an additional filter between the available and realized AM fungal species pool.

    The aim of the study was to explore the role of managerial style, work environment factors and burnout in determining job satisfaction during the implementation of quality improvement activities in a dental clinic. Quantitative research was carried out using a prestructured anonymous questionnaire to survey 302 respondents in Kaarli Dental Clinic, Estonia. Dental clinic staff assessed job satisfaction, managerial style, work stress and burnout levels through the implementation period of ISO 9000 quality management system in 2003 and annually during 2006-2009. Binary logistic regression was used to explain the impact of satisfaction with management and work organisation, knowledge about managerial activities, work environment and psychosocial stress and burnout on job satisfaction. The response rate limits were between 60% and 89.6%. Job satisfaction increased significantly from 2003 to 2006 and the percentage of very satisfied staff increased from 17 to 38 (pwork organisation and working environment, as well as factors related to career, security and planning. The average scores of emotional exhaustion showed significant decrease, correlating negatively with job satisfaction (pwork environment by decreasing burnout symptoms and increased job satisfaction in staff.

    A total of 1640 ticks collected in different geographical parts of Estonia were screened for the presence of Rickettsia species DNA by real-time PCR. DNA of Rickettsia was detected in 83 out of 1640 questing ticks with an overall prevalence of 5.1%. The majority of the ticks infected by rickettsiae were Ixodes ricinus (74 of 83), while 9 of the 83 positive ticks were Ixodes persulcatus. For rickettsial species identification, a part of the citrate synthase gltA gene was sequenced. The majority of the positive samples were identified as Rickettsia helvetica (81 out of 83) and two of the samples were identified as Rickettsia monacensis and Candidatus R. tarasevichiae, respectively. Genetic characterization based on the partial gltA gene showed that the Estonian sequences within the R. helvetica, R. monacensis and Candidatus R. tarasevichiae species demonstrated 100% similarity with sequences deposited in GenBank, originating from Rickettsia species distributed over large territories from Europe to Asia.

    To provide information on smoking differences between university faculties. Data from smoking surveys performed on 1,441 staff members and 2,308 students at the University of Tartu, Estonia, soon after the fall of communism, were analysed by faculties, using similar data from the University of Oulu, Finland (1,830 staff members, 5,947 students) for reference. Wide variations in smoking were found between faculties in Tartu, the prevalence being high among male students of theology (54%) and low among staff and students in the faculties of exercise & sports sciences (< 5%) and mathematics (< 15%). Less variation was seen in Oulu. The medical faculty showed low smoking rates in Oulu but not in Tartu. High percentages of smokers were typical of Tartu faculties representing disciplines closely connected with the country's transition (e.g. theology), and low percentages in faculties emphasising physical and mental performance (e.g. sports). The relatively high percentage of smokers in the Tartu medical faculty compared with that in Oulu can be interpreted as delayed diffusion of medical information beyond the former Iron Curtain.

    The current study locates and quantifies abandoned agricultural areas using the Geographic Information System (GIS) and evaluates the suitability of abandoned fields for bio-energy production in Tartumaa (Tartu County) in Estonia. Soils of abandoned areas are generally of low quality and thereby limited suitability for crop production; as a result soil-crop suitability analyses could form the basis of knowledge-based bio-energy planning. The study estimated suitable areas for bio-energy production using willow (Salix sp), grey alder [Alnus incana (L.) Moench], hybrid aspen (Populus tremuloides Michx.Populus tremula L.), reed canary grass (Phalaris arundinacea L.), and Caucasian goat's rue (Galega orientalis Lam.) in separate plantations. A combined land-use strategy is also presented as these crops are partially suitable to the same areas. Reed canary grass and grey alder have the highest energy potentials and each would re-use more than 80% of the available abandoned agricultural land. Energy grasses and short-rotation forestry in combined land-use strategy represents the opportunity of covering approximately a quarter of county's annual energy demand. The study estimates only agronomic potential, so further bio-energy analysis should take into account technical and economic limitations. Developed framework supports knowledge-based decision-making processes from field to regional scale to achieve sustainable bio-energy production

  20. Sedimentary record of heavy metals in Lake Rõuge Liinjärv, southern Estonia

    2007-12-01

    Full Text Available Anthropogenic impact on Lake Liinjärv (Rõuge, southern Estonia was studied back to the mid-19th century on the basis of heavy metals (Pb, Cu, Zn, Mn, and Hg and geochemical parameters of a short sediment core dated by 210Pb isotopes. The development of the lake and its sediment composition are heavily influenced by the inflow of saturated calcareous waters that cause precipitation of calcium carbonates. The concentrations of most of the metals started to increase at the end of the 1970s. This is most clearly observable for Zn, Cu, and Pb. At the same time the distribution pattern of Mn seems to be controlled mainly by the redox conditions in the hypolimneon. The main sources of pollutants in Lake Liinjärv, due to its large catchment area, are the influence of agricultural activity and atmospheric input. Organic matter is the main factor affecting heavy metal (Pb, Hg, Cu, and Zn distribution in lake sediments.
