    Cities worldwide are looking for new policies to attract travelers to shift from cars to public transport. Policies focused on reducing public transport fares are aimed at improving social inclusion and leading to a modal shift. The City of Tallinn, the capital of Estonia, has recently introduced a

    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.

    It is important to describe and understand the underlying patterns and dynamics that govern sex work in societies undergoing rapid political and social changes, its heterogeneity across populations, and its evolution through time in order to inform future research, sound policy formation, and programme delivery. To describe the socioeconomic and cultural determinants, organisational structure, distinct categories, and spatial patterning of sex work in Tallinn, Estonia, and identify recent temporal changes in sex work patterns. In-depth interviews with key informants; naturalistic observations of sex work and drug use venues, geo-mapping of sex work sites, review of media, public policy, and commissioned reports, and analyses of existing data. Sex work takes place in a hierarchy of locations in Tallinn ranging from elite brothels and "love flats" to truck stops. These sites vary in terms of their public health importance and social organisation. There are full time, part time, and intermittent male and female sex workers. Among others, the taxi driver, madam and the bartender are central roles in the organisation of sex work in Tallinn. Cell phone and internet technology enable sex work to be highly dispersed and spatially mobile. Future research and programmatic service delivery or outreach efforts should respond to the changing profile of sex work in Tallinn and its implications for STD/HIV epidemiology.

  4. 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)

    Energy Technology Data Exchange (ETDEWEB)

    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

    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.

    Full text: In Estonia, the use of radioisotopes for treatment dates back to the early 30's of the past century, when the first treatment with 232Radium was done. The Nuclear medicine units were established at Tartu University Hospital (1957) and Tallinn Central Hospital (1960). The first treatment procedures in these units were done to polycythaemia vera patients with 32P and thyrotoxicosis patients with 131iodine. The treatment of those two patient groups has continued up to the present, regardless of several drawbacks during the past 50 years. The position of nuclear medicine in Estonia strongly weakened (up to near extinction) in the beginning of 90's due to the absence of modern equipment and the cutting off of former supply channels of radiopharmaceuticals. In this tense situation, immense help was offered by IAEA to train Estonian nuclear medicine specialists. In Tallinn, IAEA organised 3 regional training courses to promote and encourage nuclear medicine and radiation protection. Good cooperation with IAEA has continued up today regarding Regional Technical Co-operation Project. In 1995 at Tallinn Central Hospital the department of nuclear medicine was modernised and 3 wards for radionuclide treatment were opened, which fully met the criteria of radiation protection. These rearrangements started the new era of radionuclide treatment in Estonia. It was possible to start treatment of thyroid cancer patients with radioiodine. In the year 2000, similar premises were arranged at Tartu University Hospital for patients from Southern Estonia. Both centres were equipped with 2-headed gamma-cameras. The number of therapy procedures has been gradually increased year by year. The first radiosynovectomy with 166Ho was performed in 2001. The first therapies with I-131MIBG of neuroblastoma were carried out in 2004. In 2006, two nuclear medicine centres of Estonia performed altogether 556 radionuclide treatment procedures.

    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

    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

    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.

  10. Data Envelopment Analysis of Helsinki-Tallinn Transportation Chains

    Directory of Open Access Journals (Sweden)

    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.

    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.

    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 paleoenvironment of the Yoldia Sea is reconstructed on the basis of 20 diatom stratigraphic records from northern Estonia. The development of the Yoldia Sea is divided into three phases. The initial Yoldia Sea phase (c. 10 300-9900 14 C years BP) is characterized by a freshwater environment. Brackish-water conditions prevailed during a short period (c. 9900-9750 14 C years BP) along the north coast of Estonia in the middle phase of the Yoldia Sea stage. During the final phase of the Yoldia Sea (c. 9750-9500 14 C years BP) a freshwater environment is registered by diatom assemblages. Regression of the shoreline, for at least 25 m, occurred around Tallinn during the Yoldia Sea stage. Postisolation coastal lakes are characterized by a shallow eutrophic hard-water environment.

    The characterization of the excited states of 9,10-phenanthrenequinone (PQ) and its derivatives substituted in the 3 and 6 positions with methoxy (PQ1), chloro (PQ2), methyl (PQ3) and fluoro (PQ3) was carried out using steady-state UV-Visible absorption spectroscopy and phosphorescence emission spectroscopy at room temperature and at 77 K. Nanosecond laser flash photolysis was used to obtain the time resolved spectra from the triplet emission decays. The compounds presented phosphorescence in benzene, chlorobenzene and acetonitrile solutions at room temperature and at 77 K. The phosphorescence of the methoxy derivative, however, was observed only at low temperature. The derivatives showed a slightly higher triplet energy than PQ. The Hammett plots were applied to correlate singlet and triplet energies with σ values that account for resonance and the radical character. It is observed that singlet and triplet energies increase with electron donating groups.

    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.

    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.

  11. Climate change scenarios and the effect of sea-level rise for Estonia

    Science.gov (United States)

    Kont, Are; Jaagus, Jaak; Aunap, Raivo

    2003-03-01

    Climate warming due to the enhanced greenhouse effect is expected to have a significant impact on natural environment and human activity in high latitudes. Mostly, it should have a positive effect on human activity. The main threats in Estonia that could be connected with sea-level rise are the flooding of coastal areas, erosion of sandy beaches and the destruction of harbour constructions. Possible climate change and its negative impacts in the coastal regions of Estonia are estimated in this paper. Climate change scenarios for Estonia were generated using a Model for the Assessment of Greenhouse-gas Induced Climate Change (MAGICC) and a regional climate change database—SCENanario GENerator (SCENGEN). Three alternative emission scenarios were combined with data from 14 general circulation model experiments. Climate change scenarios for the year 2100 indicate a significant increase in air temperature (by 2.3-4.5 °C) and precipitation (by 5-30%) in Estonia. The highest increase is expected to take place during winter and the lowest increase in summer. Due to a long coastline (3794 km) and extensive low-lying coastal areas, global climate change through sea-level rise will strongly affect the territory of Estonia. A number of valuable natural ecosystems will be in danger. These include both marine and terrestrial systems containing rare plant communities and suitable breeding places for birds. Most sandy beaches high in recreational value will disappear. However, isostatic land uplift and the location of coastal settlements at a distance from the present coastline reduce the rate of risk. Seven case study areas characterising all the shore types of Estonia have been selected for sea-level rise vulnerability and adaptation assessment. Results and estimates of vulnerability to 1.0-m sea-level rise by 2100 are presented in this paper. This is the maximum scenario according to which the actually estimated relative sea-level rise would vary from 0.9 m (SW Estonia) to 0

    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

    Two types of vaccine-derived polioviruses have been recently designated to emphasize the different origins of the evolved viruses: circulating vaccine-derived polioviruses (cVDPV) associated with outbreaks of paralytic disease and strains isolated from chronically infected immunodeficient individuals (iVDPV). We describe here a type 3 VDPV (PV3/EST/02/E252; later E252) isolated from sewage collected in Tallinn, Estonia, in October 2002. Due to aberrant properties in subtyping, the virus was subjected to detailed characterization. Partial genomic sequencing suggested that the closest relative was the oral vaccine strain PV3/Sabin, but the two virus strains shared only 86.7% of the 900 nucleotides (nt) coding for the capsid protein VP1. Phylogenetic analysis of the nearly complete genome [nt 19 to poly(A)] revealed multiple nucleotide substitutions throughout the genome and a possible Sabin 3/Sabin 1-recombination junction site in the 2C coding region. A calculation based on the estimated mutation frequency of the P1 region of polioviruses suggested that the E252 virus might have replicated in one or more individuals for approximately 10 years. No persons chronically excreting poliovirus are known in Estonia. Amino acid substitutions were seen in all known antigenic sites, which was consistent with the observed aberrant antigenic properties of the virus demonstrated by both monoclonal antibodies and human sera from vaccinated children. In spite of the apparent transmission potential, no evidence was obtained for circulation of the virus in the Estonian population.

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

    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 Abstract Background Information on the neonatal exposure to excipients is limited. Our aim was to describe the extent of excipient intake by Estonian neonates; to classify the excipients according to potential neonatal toxicity and thereby to measure the extent of exposure of neonates to potentially harmful excipients. Methods A prospective cohort study that recorded all medicines prescribed to patients aged below 28 days admitted to Tartu University Hospital from 01.02-01.08 2008 and to Tallinn Children’s Hospital from 01.02- 01.08 2009 was conducted. Excipients were identified from Summaries of Product Characteristics and classified according to toxicity following a literature review. Results 1961 prescriptions comprising 107 medicines were written for 348/490 neonates admitted. A total of 123 excipients were found in 1620 (83% prescriptions and 93 (87% medicines. 47 (38% of these excipients were classified as potentially or known to be harmful to neonates. Most neonates (97% received at least one medicine (median number 2 with potentially or known to be harmful excipient. Parabens were the most commonly used known to be harmful excipients and sodium metabisulphite the most commonly used potentially harmful excipient, received by 343 (99% and 297 (85% of treated neonates, respectively. Conclusions Hospitalised neonates in Estonia are commonly receiving a wide range of excipients with their medication. Quantitative information about excipients should be made available to pharmacists and neonatologists helping them to take into account excipient issues when selecting medicines and to monitor for adverse effects if administration of medicines containing excipients is unavoidable.

    2009-12-01

    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.

    Presently, legal regulation of participation of employees - financial participation as well as participation in decision-making - is not well developed in Estonia. On the one hand, it is due to the fact that no tradition of employee participation could have been formed after Estonia became...... in decision-making was considered to be a relict from the time under Soviet rule and, therefore, to be discredited and not worth following. On the other hand, the solution of current employment and social problems is not associated with a higher level of participation of employees....

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.

    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

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.

  3. 9,10-Phenanthrenequinone promotes secretion of pulmonary aldo-keto reductases with surfactant.

    Matsunaga, Toshiyuki; Haga, Mariko; Watanabe, Gou; Shinoda, Yuhki; Endo, Satoshi; Kajiwara, Yu; Tanaka, Hiroyuki; Inagaki, Naoki; El-Kabbani, Ossama; Hara, Akira

    2012-02-01

    9,10-Phenanthrenequinone (9,10-PQ), a major quinone in diesel exhaust particles, induces apoptosis via the generation of reactive oxygen species (ROS) because of 9,10-PQ redox cycling. We have found that intratracheal infusion of 9,10-PQ facilitates the secretion of surfactant into rat alveolus. In the cultured rat lung, treatment with 9,10-PQ results in an increase in a lower-density surfactant by ROS generation through redox cycling of the quinone. The surfactant contains aldo-keto reductase (AKR) 1C15, which reduces 9,10-PQ and the enzyme level in the surfactant increases on treatment with 9,10-PQ suggesting an involvement of AKR1C15 in the redox cycling of the quinone. In six human cell types (A549, MKN45, Caco2, Hela, Molt4 and U937) only type II epithelial A549 cells secrete three human AKR1C subfamily members (AKR1C1, AKR1C2 and AKR1C3) with the surfactant into the medium; this secretion is highly increased by 9,10-PQ treatment. Using in vitro enzyme inhibition analysis, we have identified AKR1C3 as the most abundantly secreted AKR1C member. The AKR1C enzymes in the medium efficiently reduce 9,10-PQ and initiate its redox cycling accompanied by ROS production. The exposure of A549 cells to 9,10-PQ provokes viability loss, which is significantly protected by the addition of the AKR1C3 inhibitor and antioxidant enzyme and by the removal of the surfactants from the culture medium. Thus, the AKR1C enzymes secreted in pulmonary surfactants probably participate in the toxic mechanism triggered by 9,10-PQ.

    A catalytic photometric method with a flow-injection system is described for the determination of 9,10-phenanthrenequinone. It is based on the catalytic effect of 9,10-phenanthrenequinone on the redox reaction of 1,2-dinitrobenzene with formaldehyde under alkaline conditions. 9,10-Phenanthrenequinone at the 5.0 x 10(-8)-5.0 x 10(-6)M level can be determined at a rate of 20 samples/hr. The detection limit is 1.0 x 10(-8)M (40 pg in a 10-microl injection).

    The document contains two parts. Part I stipulates the agreement of the Government of Republic of Estonia to accept safeguards on all source or special fissionable material in all peaceful nuclear activities within its territory, under its jurisdiction or carried out under its control anywhere, for the exclusive purpose of verifying that such material is not diverted to nuclear weapons or other nuclear explosive devices. Part II specifies the procedures to be applied in the implementation of the safeguards provisions of Part I. The Agreement was approved by the Agency's Board of Governors on 24 February 1992, signed in Vienna on 18 November 1997 and in Tallinn on 24 November 1997, and entered into force on 24 November 1997

    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

  1. Formation of 9,10-phenanthrenequinone by atmospheric gas-phase reactions of phenanthrene

    Science.gov (United States)

    Wang, Lin; Atkinson, Roger; Arey, Janet

    Phenanthrene is a 3-ring polycyclic aromatic hydrocarbon which exists mainly in the gas-phase in the atmosphere. Recent concern over the presence of 9,10-phenanthrenequinone in ambient particles led us to study the products of the gas-phase reactions of phenanthrene with hydroxyl radicals, nitrate radicals and ozone. The formation yields of 9,10-phenanthrenequinone were measured to be ˜3%, 33±9%, and ˜2% from the OH radical, NO 3 radical and O 3 reactions, respectively. Calculations suggest that daytime OH radical-initiated and nighttime NO 3 radical-initiated reactions of gas-phase phenanthrene may be significant sources of 9,10-phenanthrenequinone in ambient atmospheres. In contrast, the ozone reaction with phenanthrene is unlikely to contribute significantly to ambient 9,10-phenanthrenequinone.

    Full Text Available The title complex, [Mn2(C18H4O10(H2O4]n, was synthesized from manganese(II chloride tetrahydrate and 9,10-dioxo-9,10-dihydroanthracene-1,4,5,8-tetracarboxylic acid (H4AQTC in water. 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.

  6. Ethnic Minority-Majority Unions in Estonia.

    2011-08-01

    Ethnic minority-majority unions-also referred to as mixed ethnic unions-are often seen as the ultimate evidence of the integration of ethnic minorities into their host societies. We investigated minority-majority unions in Estonia, where ethnic minorities account for one-third of the total population (Russians 26%, followed by Ukrainians, Byelorussians, Finns and other smaller groups). Using data from the 2000 Estonian census and regression models, we found that Slavic women are less likely to be in minority-majority unions than are members of other minority groups, with Russians being the least likely. Finns, who are culturally most similar to the Estonian majority population, are the most likely to form a union with an Estonian. For ethnic minority women, the likelihood of being in minority-majority unions is highest in rural areas and increases over generations, with third-generation immigrants being the most likely. Estonian women are most likely to have a minority partner when they or their parents were born abroad and when they live in urban areas. Our findings suggest that both the opportunity to meet potential partners and openness to other ethnic groups are important factors for understanding the dynamics of minority-majority unions.

  7. Thunderstorms caused by southern cyclones in Estonia

    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.

The propagandistic nature of the original narrative as a legitimizing legend for the Jehu dynasty puts it out of contention as a reliable source of history.

    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)

    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.

    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.

    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 {Phi}{sub NH{sub 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 {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.

    2017-06-01

    Full Text Available Previous late Precambrian and Cambrian correlation charts of Estonia, summarizing the regional stratigraphic nomenclature of the 20th century, date back to 1997. The main aim of this review is updating these charts based on recent advances in the global Precambrian and Cambrian stratigraphy and new data from regions adjacent to Estonia. The term ‘Ediacaran’ is introduced for the latest Precambrian succession in Estonia to replace the formerly used ‘Vendian’. Correlation with the dated sections in adjacent areas suggests that only the latest 7–10 Ma of the Ediacaran is represented in the Estonian succession. The gap between the Ediacaran and Cambrian may be rather substantial. The global fourfold subdivision of the Cambrian System is introduced for Estonia. The lower boundary of Series 2 is drawn at the base of the Sõru Formation and the base of Series 3 slightly above the former lower boundary of the ‘Middle Cambrian’ in the Baltic region, marked by a gap in the Estonian succession. The base of the Furongian is located near the base of the Petseri Formation.

    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

    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.

    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.

    Bis(acetylacetonato)ruthenium complexes [Ru(acac)2(Q1-3)], 1-3, incorporating redox non-innocent 9,10-phenanthrenequinonoid ligands (Q1 = 9,10-phenanthrenequinone, 1; Q2 = 9,10-phenanthrenequinonediimine, 2; Q3 = 9,10-phenanthrenequinonemonoimine, 3) have been characterised electrochemically, spectroscopically and structurally. The four independent molecules in the unit cell of 2 are involved in intermolecular hydrogen bonding and π-π interactions, leading to a 2D network. The oxidation state-sensitive bond distances of the coordinated ligands Q(n) at 1.296(5)/1.289(5) Å (C-O), 1.315(3)/1.322(4) Å (C-N), and 1.285(3)/1.328(3) Å (C-O/C-N) in 1, 2 and 3, respectively, and the well resolved (1)H NMR resonances within the standard chemical shift range suggest DFT supported variable contributions from valence formulations [Ru(III)(acac)2(Q˙(-))] (spin-coupled) and [Ru(II)(acac)2(Q(0))], respectively. Complexes 1-3 exhibit one oxidation and two reduction steps with comproportionation constants Kc∼ 10(7)-10(22) for the intermediates. The electrochemically generated persistent redox states 1(n) (n = 0, 1-, 2-) and 2(n)/3(n) (n = 1+, 0, 1-, 2-) have been analysed by UV-vis-NIR spectroelectrochemistry and by EPR for the paramagnetic intermediates in combination with DFT and TD-DFT calculations, revealing significant differences in the oxidation state distribution at the {Ru-Q} interface for 1(n)-3(n). In particular, the diminished propensity of the NH-containing systems for reduction results in the preference for Ru(II)(Q(0)) relative to Ru(III)(Q˙(-)) (neutral compounds) and for Ru(II)(Q˙(-)) over the Ru(III)(Q(2-)) alternative in the case of the monoanionic complexes.

    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

    It has been widely recognized that nitric oxide (NO) suppresses oxidative damage of endothelial cell, but little is known about its pathophysiological role in apoptotic induction by 9,10-phenanthrenequinone (9,10-PQ), a major quinone component in diesel exhaust particles. Here, we have investigated the change in NO level in human aortic endothelial cells and the effect of NO in each step of apoptotic signaling initiated by 9,10-PQ. Treatment with 9,10-PQ evoked a bell-shaped production of NO, which was presumably due to increase in an active form of endothelial NO synthase. Pretreatment with exogenous NO decreased the susceptibility of the cells to 9,10-PQ, and retrieved from apoptotic signaling (reactive oxygen species generation, glutathione depletion and caspase activation) induced during exposure to high concentrations of 9,10-PQ. In addition, inhibition of endogenous NO production augmented the toxicity of 9,10-PQ. Interestingly, the 9,10-PQ treatment resulted in marked decreases in the proteasomal activities, which were partially abrogated by NO and a cell-permeable cGMP analog. These results indicate that proteasomal dysfunction by oxidative stress participates in the 9,10-PQ-induced apoptotic signaling and is ameliorated by NO via a cGMP-dependent pathway, thereby suggesting the protective role of NO in vascular damage caused by 9,10-PQ.

Metastable, rectangular tetramers of this molecule form in which the net molecular dipoles all orient toward the center of the cluster. This structure does not allow for additional hydrogen bonding and thus the origin of its metastability is not clear. We compare this feature to other structures observed on this surface, as well as those formed during the deposition of 9-fluorenone, which does not exhibit this anomalous clustering behavior.

    In this work we demonstrate that the room-temperature deposition of the organic molecule 9,10-phenanthrenequinone (PQ) reduces the surface defect density of the silicon (100) surface by chemically bonding to the surface dangling bonds. Using various spectroscopic measurements we have investigated the electronic structure and band alignment properties of the PQ/Si interface. The band-bending at the PQ-passivated silicon surface is negligible for both n- and p-type substrates, demonstrating a low density of surface defects. Finally we show that PQ forms a semiconducting wide-bandgap type-I heterojunction with silicon.

    The 60 Co γ-radiolysis of aqueous solutions of sodium 9,10-anthraquinone-2-sulfonate has been studied in acidic, unbuffered, and alkaline conditions and with addition of N 2 O and 2-propanol. Mechanisms are proposed to account for the yields of H 2 O 2 and hydroxylated anthraquinone sulfonates. In neutral solution, in the absence of O 2 , the OH and e - adducts undergo preferential cross termination. Reduction of the OH adduct leads to dehydration and regeneration of the quinone. (author)

    1999-01-01

    The present monograph tries to give a comprehensive overview of the present situation of the Estonian energy sector and treats its possible future development in the context of global climate change. An important part of the book is devoted to one of the most topical issues in global climate change studies: economic analysis of the options of reducing emissions of greenhouse gases in a small country in transition to a market economy full of various untraditional restrictions and policy options. The solutions proposed in the work will serve as basis in the decision-making process to design the policy options in the next century. The present analysis of greenhouse gases mitigation options is concentrated on the energy sector. Estonia is currently in the process of intensive transition from a centrally planned to a market economy. Reforming of the whole economy, including the energy sector, is underway 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 further forecasts and projections. Estonian research team has managed with the complicated task of analysing the most probable greenhouse gases mitigation options to be used in the period up till 2035. The thorough analysis of the whole energy sector includes also the present and future use of the highly prioritised renewable energy sources. Biomass (mainly wood), wind energy and hydro energy were analysed bearing in mind the possible future development paths of Estonia. 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 to reduce CO 2 , SO 2 and NO x emissions, which makes them highly important in the process of following the binding agreements of international treaties on pollution abatement.

    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{sup 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{sup -1}, and anthrone, (31.4 {+-} 3.2) kJ . mol{sup -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{sup -1} and -(128.3 {+-} 5.4) kJ . mol{sup -1}, respectively.

    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)

    Full Text Available The presentation aims to bring some clarification about the relationship in Estonian old-new architecture. Estonia has a very valuable historical and architectural heritage, bringing together works and urban ensembles from different eras and styles. The medieval period is represented by monuments dating back from more than 800 years, with Germanic and Norse influences. From Tsarist rule (1721-1920 has left important neoclassical buildings. Estonia's independence period between the two world wars (1920-1940 was particularly prolific in modern architecture, from Art Nouveau to International Style. Soviet occupation period (1944-1991, has left, outside of the dwelling houses some reference works. After regaining its independence, Estonian architecture oriented towards Scandinavian and Western models, while keeping in it the local spirit, which has led to some remarkable achievements.

    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.

    Electronic properties, optical absorption and chemical reactivity of organic ketones and quinone molecules have been widely studied because of their ability to abstract hydrogen atoms from other organic molecules once excited to the highly reactive 3(n, π*) state. Most of these studies were done for liquid solutions. In this joint theoretical and experimental study, we focused on excited states of pentaerythritol tetranitrate (PETN) crystals doped with 9,10-phenanthrenequinone (PQ) molecules. We explored electronic properties of the system and estimated energies of the electronic excitations. It was found that PQ molecule in its excited triplet state can catalyze unusual decomposition pathways of PETN, which are not attainable through the potential surface of the ground state. We discuss mechanisms of such autocatalytic reactions in PETN-PQ complexes. Research is supported by the US ONR (Grants N00014-16-1-2069 and N00014-16-1-2346) and NSF. We used NERSC, XSEDE and MARCC computational resources.

    Merged organic-silicon heterojunction devices require the passivation of dangling bonds at the silicon surface, preferably with a low-temperature process. In this paper, we demonstrate the high-quality passivation of the silicon (100) surface using an organic molecule (9,10-phenanthrenequinone, PQ). PQ reacts with the dangling bonds, thus providing a bridge between organic semiconductors and silicon. We measure low recombination velocities (˜150 cm/s) at the PQ-silicon interface. Metal/organic-insulator/silicon capacitors and transistors prove that at PQ-silicon interface, the Fermi level can be modulated. The formation of an inversion layer with electron mobility of 600 cm2/V•s further demonstrates the passivation quality of PQ.

    9,10-Phenanthrenequinone (PQ), one of the components of atmospheric pollutants, has potent harmful effects on human health. PQ in airborne particulates collected in Nagasaki city was determined by HPLC with fluorescence derivatization. PQ extracted from airborne particulates using methanol was derivatized with benzaldehyde in the presence of ammonium acetate to give a fluorescent compound. The average concentration (mean+/-SD, n=52) of PQ found in airborne particulates collected from July 1997 to June 1998 was 0.287+/-0.128 ng m-3. Concentrations of PQ in winter were higher than those in summer. In a weekly variation study, PQ concentrations were higher during weekdays and lower at weekend. The levels of PQ were obviously correlated with those of phenanthrene (PH) that is considered as a parent compound of PQ. This observation suggested that PQ was emitted into the atmosphere from the same source as PH, or PQ was converted from PH in the atmosphere.

    Full Text Available The problems of diagnosis of psycho-physiological status of boys in the prepubertal stage of their biological development is considered. The study involved 94 boys aged 9-10 years. They were assessed by parameters of physical development, the functional state of the nervous, cardio-respiratory, muscular and sensory systems and motor fitness, energy and properties of psychodynamics. It is shown that the failure of the approach to assess children's physical health on the grounds of their physical development. Children of this age are characterized by a lag in terms of static lung volume, and vice versa - ahead of age norms in the development of pulmonary ventilation function and resistance to hypoxia. Central hemodynamic parameters vary within age norms. From the observed dominance of neurodynamic mechanisms of excitation and response of advanced type. The established features of the psycho-physiological status, can be used as prognostic indicators in guiding children to sports activities.

    The estimated cancer risk from diesel exhaust particles (DEP) in the air is approximately 70% of the cancer risk from all air pollutants. DEP is comprised of a complex mixture of chemicals whose carcinogenic potential has not been adequately assessed. The polycyclic aromatic hydrocarbon quinone 9,10-phenanthrenequinone (9,10 PQ) is a major component of DEP and a suspect genotoxic agent for DEP induced DNA damage. 9,10 PQ undergoes redox cycling to produce reactive oxygen species that can lead to oxidative DNA damage. We used two systems in the yeast Saccharomyces cerevisiae to examine possible differential genotoxicity of 9,10 PQ. The DEL assay measures intra-chromosomal homologous recombination leading to DNA deletions and the CAN assay measures forward mutations leading to canavanine resistance. Cells were exposed to 9,10 PQ aerobically and anaerobically followed by DNA damage assessment. The results indicate that 9,10 PQ induces DNA deletions and point mutations in the presence of oxygen while exhibiting negligible effects anaerobically. In contrast to the cytotoxicity observed aerobically, the anaerobic effects of 9,10 PQ seem to be cytostatic in nature, reducing growth without affecting cell viability. Thus, 9,10 PQ requires oxygen for genotoxicity while different toxicities exhibited aerobically and anaerobically suggest multiple mechanisms of action.

    9,10-Phenanthrenequinone (9,10-PQ), a major component in diesel exhaust particles, is suggested to generate reactive oxygen species (ROS) through its redox cycling, leading to cell toxicity. l-Xylulose reductase (XR), a NADPH-dependent enzyme in the uronate pathway, strongly reduces alpha-dicarbonyl compounds and was thought to act as a detoxification enzyme against reactive carbonyl compounds. Here, we have investigated the role of intracellular ROS generation in apoptotic signaling in human acute T-lymphoblastic leukemia MOLT-4 cells treated with 9,10-PQ and the role of XR in the generation of ROS. Treatment with 9,10-PQ elicited not only apoptotic signaling, including mitochondrial membrane dysfunction and activation of caspases and poly(ADP-ribose) polymerase, but also intracellular ROS generation and consequent glutathione depletion. The apoptotic effects of 9,10-PQ were drastically mitigated by pretreatment with intracellular ROS scavengers, such as N-acetyl-l-cysteine, glutathione monoethyl ester, and polyethylene glycol-conjugated catalase, indicating that intracellular ROS generation is responsible for the 9,10-PQ-evoked apoptosis. Surprisingly, the ROS generation and cytotoxicity by 9,10-PQ were augmented in an XR-transformed cell line. XR indeed reduced 9,10-PQ and produced superoxide anion through redox cycling. In addition, the expression levels of XR and its mRNA in the T lymphoma cells were markedly enhanced after the exposure to 9,10-PQ, and the induction was completely abolished by the ROS scavengers. Moreover, the 9,10-PQ-induced apoptosis was partially inhibited by the pretreatment with XR-specific inhibitors. These results suggest that initially produced ROS induce XR, which accelerates the generation of ROS.

    Full Text Available The distribution, morphology, fillings, and origin of buried valleys are discussed. The direction of the valleys varies from NW to NE. Within the Viru-Harju Plateau the valleys have a more or less symmetric profile, but asymmetric profiles are dominating in the pre-klint area. They are mainly filled with glacial (till, glaciofluvial (sand, gravel, and pebbles, glacio­lacustrine (varved clay, and marine (fine-grained sand deposits. The Tallinn valley with its tributary valleys (Saku and Sausti and fore-klint branches (Harku, Lilleküla, and Kadriorg looks like a river system. The fore-klint branches extend over 20 km in the Gulf of Finland. They are probably tributaries of the ancient river Pra-Neva. Most likely, the formation of valleys was continuous, starting from pre-Quaternary river erosion, and was sculptured by variable processes during the ice ages and influenced by flowing water during the interglacial periods.

    Solvent effects play a vital role in various chemical, physical, and biological processes. To gain a fundamental understanding of the solute-solvent interactions and their implications on the energy level re-ordering and structure, UV-VIS absorption, resonance Raman spectroscopic, and density functional theory calculation studies on 9,10-phenanthrenequinone (PQ) in different solvents of diverse solvent polarity has been carried out. The solvatochromic analysis of the absorption spectra of PQ in protic dipolar solvents suggests that the longest (1n-π1*; S1 state) and the shorter (1π-π1*; S2 state) wavelength band undergoes a hypsochromic and bathochromic shift due to intermolecular hydrogen bond weakening and strengthening, respectively. It also indicates that hydrogen bonding plays a major role in the differential solvation of the S2 state relative to the ground state. Raman excitation profiles of PQ (400-1800 cm-1) in various solvents followed their corresponding absorption spectra therefore the enhancements on resonant excitation are from single-state rather than mixed states. The hyperchromism of the longer wavelength band is attributed to intensity borrowing from the nearby allowed electronic transition through vibronic coupling. Computational calculation with C2ν symmetry constraint on the S2 state resulted in an imaginary frequency along the low-frequency out-of-plane torsional modes involving the C=O site and therefore, we hypothesize that this mode could be involved in the vibronic coupling.

    Polycyclic aromatic hydrocarbons (PAHs) have earned considerable attention due to their widespread environmental distribution and toxicity. In the environment, PAHs decompose by a variety of biotic and abiotic pathways. In both polar and nonpolar environments, phenanthrene (Phe, a common, three-ring PAH) is converted by sunlight to more polar products such as 9,10-phenanthrenequinone (PheQ) and subsequent oxidation products such as the corresponding open-ring dicarboxylic acid product. Biodegradation of phenanthrene also usually leads to oxidative metabolites, and eventually ends in mineralization. Our experimental objective was to investigate the photodegradation of phenanthrene and determine the effect of reaction products such as PheQ on microbial biodegradation of two- and three-ring PAHs. Abiotic experiments were performed to examine the photolytic breakdown of Phe; Phe was converted to PheQ, which catalyzed its own formation. In biodegradation experiments PheQ (0.04-4 mg/L) caused marked inhibition of naphthalene (Nap) biodegradation by a Burkholderia species; Phe did not. Only 20% of the naphthalene was degraded in the presence of PheQ compared with 75% in the control culture with no PheQ added. No PAH-degrading cultures were able to use PheQ as sole carbon source; however, the Phe-degrading enrichment culture dominated by a Sphingomonas species was able to degrade PheQ cometabolically in the presence of Phe. These results may explain why photooxidized phenanthrene-containing mixtures can resist biodegradation.

    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.

Semple (Lancaster University, UK) The effects of many environmental exposures to either single contaminants or to mixtures still remain to be properly assessed in ecotoxicological and human toxicological settings. Such assessments need to be carried out using relevant biological assays. On a mechanistic basis, future studies need to be able to extrapolate exposure to disease risk. It is envisaged that such an approach would lead to the development of appropriate strategies to either reduce exposures or to initiate preventative measures in susceptible individuals or populations. To mark the opening of a new Institute, the Lancaster Environmental Centre, an environmental health workshop was held over 2 days (9-10 September 2003) at Lancaster University, UK. The fate, behaviour and movement of chemicals in the environment, together with environmental exposures and human health, biomarkers of such exposures, hormone-like compounds and appropriate genetic toxicology methodologies, were discussed.

    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.

Libraries are pioneers in initiating collaborationprojects in digitisation. Due to the joint efforts of the National Library, the Archive Library of the Estonian Literature Museum and the Tallinn University Academic Library a big collection of old Estonian newspapers is available by internet. The project is titled DEA (Digitized Estonian Newspapers. The aim of the project Red Book of Estonian publications, 1535–1850 was to create a theoretical basis for elaborating criteria that would enable decision making and determination preservation priorities of the Estonian book heritage. At the moment there is not much collaboration between different types of memory institutions. The joint projects like DEA and Red Bookof Estonian Publications give hope that together difficult problems of preservation can be better solved and users will get better access to Estonian cultural heritage.

    The reaction of 9,10-phenanthrenequinone (PQ) with [M(II)(H)(CO)(X)(PPh(3))(3)] in boiling toluene leads to the homolytic cleavage of the M(II)-H bond, affording the paramagnetic trans-[M(PQ)(PPh(3))(2)(CO)X] (M = Ru, X = Cl, 1; M = Os, X = Br, 3) and cis-[M(PQ)(PPh(3))(2)(CO)X] (M = Ru, X = Cl, 2; M = Os, X = Br, 4) complexes. Single-crystal X-ray structure determinations of 1, 2·toluene, and 4·CH(2)Cl(2), EPR spectra, and density functional theory (DFT) calculations have substantiated that 1-4 are 9,10-phenanthrenesemiquinone radical (PQ(•-)) complexes of ruthenium(II) and osmium(II) and are defined as trans-[Ru(II)(PQ(•-))(PPh(3))(2)(CO)Cl] (1), cis-[Ru(II)(PQ(•-))(PPh(3))(2)(CO)Cl] (2), trans-[Os(II)(PQ(•-))(PPh(3))(2)(CO) Br] (3), and cis-[Os(II)(PQ(•-))(PPh(3))(2)(CO)Br] (4). Two comparatively longer C-O [average lengths: 1, 1.291(3) Å; 2·toluene, 1.281(5) Å; 4·CH(2)Cl(2), 1.300(8) Å] and shorter C-C lengths [1, 1.418(5) Å; 2·toluene, 1.439(6) Å; 4·CH(2)Cl(2), 1.434(9) Å] of the OO chelates are consistent with the presence of a reduced PQ(•-) ligand in 1-4. A minor contribution of the alternate resonance form, trans- or cis-[M(I)(PQ)(PPh(3))(2)(CO)X], of 1-4 has been predicted by the anisotropic X- and Q-band electron paramagnetic resonance spectra of the frozen glasses of the complexes at 25 K and unrestricted DFT calculations on 1, trans-[Ru(PQ)(PMe(3))(2)(CO)Cl] (5), cis-[Ru(PQ)(PMe(3))(2)(CO)Cl] (6), and cis-[Os(PQ)(PMe(3))(2)(CO)Br] (7). However, no thermodynamic equilibria between [M(II)(PQ(•-))(PPh(3))(2)(CO)X] and [M(I)(PQ)(PPh(3))(2)(CO)X] tautomers have been detected. 1-4 undergo one-electron oxidation at -0.06, -0.05, 0.03, and -0.03 V versus a ferrocenium/ferrocene, Fc(+)/Fc, couple because of the formation of PQ complexes as trans-[Ru(II)(PQ)(PPh(3))(2)(CO)Cl](+) (1(+)), cis-[Ru(II)(PQ)(PPh(3))(2)(CO)Cl](+) (2(+)), trans-[Os(II)(PQ)(PPh(3))(2)(CO)Br](+) (3(+)), and cis-[Os(II)(PQ)(PPh(3))(2)(CO)Br](+) (4(+)).

    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

    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

    Transient receptor potential ankyrin 1 (TRPA1) is activated by noxious cold, mechanical stimulation, and irritant chemicals. In our recent study, 9, 10-phenanthrenequinone (9,10-PQ) is the most potent irritant for activation of NRF2 among 1395 cigarette smoke components and it may be, therefore, important to find its additional targets. Here, we show that 9,10-PQ functions as an activator of TRPA1 in human embryonic kidney (HEK) cells expressing human wild-type TRPA1 (HEK-wTRPA1) and human alveolar A549 (A549) cells. Application of 9,10-PQ at 0.1-10 μmol/L induced a concentration-dependent Ca 2+ response as well as inward currents at -50 mV in HEK-wTRPA1 cells. The current response was blocked by TRPA1 antagonists, HC-030031 (HC) and A-967079. To test whether 9,10-PQ affects the cysteine residues of TRPA1, we expressed mutant TRPA1 channels in HEK cells (HEK-muTRPA1) in which six different cysteine residues were replaced with serine. Among them, a mutation of cysteine 621 (C621S) abolished the 9,10-PQ-induced Ca 2+ and current responses. The channel activity induced by 9,10-PQ was also abolished in excised inside-out patches isolated from HEK-muTRPA1 cells with the C621S substitution. Although a mutation of cysteine 665 (C665S) reduced the 9,10-PQ-induced response, channel sensitization by pretreatment with Cu 2+ plus 1,10-phenanthroline and by internal dialysis of 3 μmol/L Ca 2+ restored the response. However, a double mutant with C621S and C665S substitutions had little response to 9,10-PQ, even when sensitized by Ca 2+ dialysis. In A549 cells, 9,10-PQ induced an HC-sensitive Ca 2+ response. Our findings demonstrate that 9,10-PQ activation of human TRA1 is dependent on cysteine residues 621 and 665. © 2017 The Authors.

    Polycyclic aromatic hydrocarbon quinones (PAHQs) are components in airborne particulate matter (PM) and generate reactive oxygen species (ROS) in a redox cycling process. 9,10-Phenanthrenequinone (9,10-PQ) is a PAHQ found in diesel exhaust particulates and PM. When inhaled, it produces much more ROS than other PAHQs. We hypothesized that urinary metabolites of 9,10-PQ could serve as biomarkers of PAHQ exposure. Here, we describe methods for pretreating urine samples and analyzing 9,10-PQ metabolites by liquid chromatography with tandem mass spectrometry (LC-MS/MS). In urine from rats intraperitoneally injected with 9,10-PQ, the monoglucuronide of 9,10-dihydroxyphenanthrene (9,10-PQHG) was found to be a major metabolite of 9,10-PQ. 9,10-PQHG was also identified in the urine of a nonoccupationally exposed human by its retention time and MS/MS spectra. Furthermore, the urine contained hardly any free (unmetabolized) 9,10-PQ, but treating it with hydrolytic enzymes released 9,10-PQ from conjugated metabolites such as 9,10-PQHG. The concentrations of 9,10-PQHG in urine samples from nonoccupationally exposed subjects who lived in a suburban area were 2.04-19.08 nmol/mol creatinine. This study is the first to demonstrate the presence of 9,10-PQHG in human urine. Determination of urinary 9,10-PQHG should be useful for determining 9,10-PQ exposure.

    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

    We investigated the synergic effects of components of particulate matter with aerodynamic diameters ≤2.5μm (PM2.5) on airway inflammation. Co-exposure to cadmium (Cd) and 9,10-phenanthrenequinone (9,10-PQ) additively/synergistically increased pro-inflammatory responses in airway epithelial cells, whereas co-exposure to Cd and phenanthrene resulted in no acceleration. These results suggest that the combination of metal and a quinone derivative can contribute to the exacerbation of respiratory diseases by PM2.5. Copyright © 2017 Elsevier B.V. All rights reserved.

    (Z/E)-3-(1,8-Dichloro-9,10-dihydro-9,10-ethanoanthracen-11-yl)acrylaldehyde 2 has been investigated experimentally and theoretically. The Wittig reaction of 1,8-dichloro-9,10-dihydro-9,10-ethanoanthracene-11-carbaldehyde 1 and (triphenylphosphoranylidene) acetaldehyde in toluene under reflux conditions resulted in compound 2. Spectroscopic characterization of compound 2 was performed by the Fourier-transform infrared spectroscopy, nuclear magnetic resonance, and high-resolution mass spectroscopy techniques. Density functional theory (DFT) calculations were conducted to study various global and local reactive properties. The spectra were also obtained by DFT calculations and corresponding comparisons were performed to validate the level of theory. Using DFT calculations, reactivity has been studied based on frontier molecular orbitals, charge distribution, average local ionization energies, Fukui functions, and bond dissociation energies for hydrogen abstraction. Molecular dynamics simulations have been used to investigate the influence of water as a solvent for compound 2. Finally, compound 2 was docked into the central and allosteric binding sites of the serotonin transporter enzyme and was found to be a good candidate as an antidepressant-like compound.

Graphical correlation of the Viirelaid and Paatsalu sections shows a stronger linear correlation for zonal conodonts than for chitinozoans and scolecodonts. In the given case, this is caused by different nature of zones: chitinozoan zones are based on appearances and/or disappearances of ordinal taxa whereas conodont zonation corresponds, as a rule, to evolutionary succeeding species in the Pterospathodus lineage. At the same time, the positions of chitinozoan zones in the Viirelaid, Ruhnu, Aizpute, and Paatsalu cores are oscillating with respect to conodont zones.

    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.

    According to the Medical Exposure Directive (97/43/Euratom) the radiation doses to patients should be measured in every hospital and doses should be compared to the reference doses established by the competent authorities. Special attention should be paid to the paediatric x-ray examinations, because the paediatric patients are more radiosensitive than adult patients. The requirement of measurements of radiation dose to patients is not yet included in the Estonian radiation act, but the purpose to join the European Communities makes the quality control in radiology very actual in Estonia. The necessity exists to introduce suitable measurement methods in the Xray departments of Estonian hospitals for establishing feedback system for radiologists, radiographers and medical physicists in optimising the radiation burden of patients and image quality.

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.

    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.

  9. Tissue-specific regulation of CXCL9/10/11 chemokines in keratinocytes: Implications for oral inflammatory disease.

    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.

  10. The interactions of 9,10-phenanthrenequinone with glyceraldehyde-3-phosphate dehydrogenase (GAPDH), a potential site for toxic actions.

    Glyceraldehyde-3-phosphate dehydrogenase (GAPDH) catalyzes the oxidative phosphorylation of glyceraldehyde 3-phosphate to 1,3-diphosphoglycerate, one of the precursors for glycolytic ATP biosynthesis. The enzyme contains an active site cysteine thiolate, which is critical for its catalytic function. As part of a continuing study of the interactions of quinones with biological systems, we have examined the susceptibility of GAPDH to inactivation by 9,10-phenanthrenequinone (9,10-PQ). In a previous study of quinone toxicity, this quinone, whose actions have been exclusively attributed to reactive oxygen species (ROS) generation, caused a reduction in the glycolytic activity of GAPDH under aerobic and anaerobic conditions, indicating indirect and possible direct actions on this enzyme. In this study, the effects of 9,10-PQ on GAPDH were examined in detail under aerobic and anaerobic conditions so that the role of oxygen could be distinguished from the direct effects of the quinone. The results indicate that, in the presence of the reducing agent DTT, GAPDH inhibition by 9,10-PQ under aerobic conditions was mostly indirect and comparable to the direct actions of exogenously-added H2O2 on this enzyme. GAPDH was also inhibited by 9,10-PQ anaerobically, but in a somewhat more complex manner. This quinone, which is not considered an electrophile, inhibited GAPDH in a time-dependent manner, consistent with irreversible modification and comparable to the electrophilic actions of 1,4-benzoquinone (1,4-BQ). Analysis of the anaerobic inactivation kinetics for the two quinones revealed comparable inactivation rate constants (k(inac)), but a much lower inhibitor binding constant (K(i)) for 1,4-BQ. Protection and thiol titration studies suggest that these quinones bind to the NAD+ binding site and modify the catalytic thiol from this site. Thus, 9,10-PQ inhibits GAPDH by two distinct mechanisms: through ROS generation that results in the oxidization of GAPDH thiols, and by an

    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)

    9,10-Phenanthrenequinone (PQ) is harmful environmental pollutant that is detected in airborne particulates. The measurement of PQ in the air should be necessary to evaluate the potential adverse effects of PQ on human health. We have recently developed a determination method for PQ based on the fluorescence derivatization of PQ using benzaldehyde and ammonium acetate as a reagent. In this study, in order to obtain more sensitive and selective fluorescence derivatization reaction, we measured ...

    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

    Bis(pyridine)(9,10-phenanthrenequinone)(9,10-phenanthrenediolato)copper(II), Cu(py)(2)(PhenCat)(PhenBQ), has been prepared by treating copper metal with 9,10-phenanthrenequinone in pyridine solution. In dilute solution, both Cu(py)(2)(PhenCat)(PhenBQ) and the related complex Cu(tmeda)(PhenCat)(PhenBQ) lose PhenBQ to form Cu(II)L(2)(PhenCat), where L(2)= tmeda, 2 py. EPR spectra recorded at temperatures between 300 and 77 K reveal the presence of species with radical and metal localized spins together at equilibrium. Equilibria between Cu(II)L(2)(PhenCat) and Cu(I)L(2)(PhenSQ) redox isomers are solvent dependent, with a shift to higher temperature for polar solvents. Both complexes are oxygen sensitive, reacting with dioxygen to give complexes of diphenic acid. Structural characterization on products obtained with tmeda show that dioxygen insertion across the C-C bond within the chelate ring leads to dimeric products with adjacent Cu(II) ions bridged by diphenate ligands. The addition of O(2) to Cu(tmeda)(PhenCat) in acetonitrile solution at 0 degrees C appears to form a peroxo complex, tentatively identified as Cu(tmeda)(O(2))(PhenQ) on the basis of iodometric titration, as the precursor to the diphenate complex.

    2011-01-01

    The paper presents experiences gained and progress achieved during the ongoing Sillamaee Radioactive Tailings Pond Remediation Project. The Sillamaee tailings pond covering ca. 50 ha is located next to the shoreline of the Baltic Sea near Sillamaee town in Estonia. Tailings disposal included mill tailings from uranium ore processing (1953-1977), enriched uranium refining (1977- 1990), from rare earth elements processing (since 1970; tailings disposal ended 2003), black shale processing (1948-1953) and liquid oil-shale ashes from the local power plant. Initial environmental and geotechnical investigations identified insufficient safety of the tailings pond for radiological, environmental and geotechnical reasons. Contaminated seepage was entering the Baltic Sea. The 25 m high northern tailings dam was affected by marine erosion and the stability of the dam was found to be insufficient. Therefore the multi-national Sillamaee Radioactive Tailings Pond Remediation Programme was launched in 1998 jointly financed by North European Countries (NEFCO), EU and Estonia. The remediation project included the following crucial remediation steps: Drillings and samplings including geotechnical, (hydro-)geological and environmental investigations (2000-2001); relocation of mine wastes and contaminated soils from the surrounding area onto the tailings pond for interim covering (2000-2003); initial stabilization measures (2001-2003) including a 1080 m long shore protection embankment along the shoreline of the Baltic Sea, a 720 m long pile grillage for stabilizing the northern dam including two rows of 15 m or 18 m deep continuous flight auger piles, a 580 m long and 12-18 m deep cut-off wall, a deep gravel-filled drainage ditch (520 m, up to 12 m deep) and a deep drainage trench. Reshaping of the dams with respect to long term dam stability and contouring of the pond area with respect to long term settlement portions lasted from 2003 till 2004 building up a ridge-type surface

    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

    9,10-Phenanthrenequinone (9,10-PQ), a major quinone found in diesel exhaust particles, is considered to generate reactive oxygen species (ROS) through its redox cycling. Here, we show that 9,10-PQ evokes apoptosis in human aortic endothelial cells (HAECs) and its apoptotic signaling includes ROS generation and caspase activation. The 9,10-PQ-induced cytotoxicity was inhibited by ROS scavengers, indicating that intracellular ROS generation is responsible for the 9,10-PQ-induced apoptosis. Comparison of mRNA expression levels and kinetic constants in the 9,10-PQ reduction among 10 human reductases suggests that aldo-keto reductase 1C3 (AKR1C3) is a 9,10-PQ reductase in HAECs. In in vitro 9,10-PQ reduction by AKR1C3, the reduced product 9,10-dihydroxyphenanthrene and superoxide anions were formed, suggesting the enzymatic two-electron reduction of 9,10-PQ that thereby causes oxidative stress through its redox cycling. In addition, the participation of AKR1C3 in 9,10-PQ-redox cycling was confirmed by the data that AKR1C3 overexpression in endothelial cells augmented the ROS generation and cytotoxicity by 9,10-PQ, and the ROS scavengers inhibited the toxic effects. Pretreatment of the overexpressing cells with AKR1C3 inhibitors, flufenamic acid and indomethacin, suppressed the 9,10-PQ-induced GSH depletion. These results suggest that AKR1C3 is a key enzyme in the initial step of 9,10-PQ-induced cytotoxicity in HAECs.

  1. The regional approach in the policy of the Russian Federation towards the Republic of Estonia

    2013-09-01

    Full Text Available This author uses regionalism as a theoretical framework for analyzing the foreign policy of the Russian Federation towards the Republic of Estonia. Regionalism is interpreted as a situation, when a political leader’s beliefs change depending on what region of the world is considered. Leaders of great powers often assume that, for example, small European countries are subject to a treatment different from that of small Middle Eastern countries. The method of operational coding is employed to identify the impact of the regional approach on the beliefs of political leaders. The author comes to the conclusion that Russia’s policy towards Estonia largely depends on Russia’s policy towards the regions which the Russian elite relate Estonia to — the Baltic States, Northern Europe, and Europe as a whole. The results of the study can further the understanding of Russia’s policy towards Estonia both in Russia and abroad. Lack of understanding sometimes results in sharing the views of radical Estonian politicians who claim that Russia’s policy towards Estonia is unpredictable and thus poses a threat to security and stability in Europe.

    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.

    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.

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.

    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

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

    Science.gov (United States)

    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.

    9,10-Phenanthrenequinone (9,10-PQ), a redox-active quinone in diesel exhausts, triggers cellular apoptosis via reactive oxygen species (ROS) generation in its redox cycling. This study found that induction of CCAAT/enhancer-binding protein-homologous protein (CHOP), a pro-apoptotic factor derived from endoplasmic reticulum stress, participates in the mechanism of rat endothelial cell damage. The 9,10-PQ-mediated CHOP induction was strengthened by a proteasome inhibitor (MG132) and the MG132-induced cell sensitization to the 9,10-PQ toxicity was abolished by a ROS inhibitor, suggesting that ROS generation and consequent proteasomal dysfunction are responsible for the CHOP up-regulation caused by 9,10-PQ. Aldo-keto reductase (AKR) 1C15 expressed in rat endothelial cells reduced 9,10-PQ into 9,10-dihydroxyphenanthrene concomitantly with superoxide anion formation, implying its participation in evoking the 9,10-PQ-redox cycling. The 9,10-PQ-induced damage was augmented by AKR1C15 over-expression. 9,10-PQ also provoked the AKR1C15 up-regulation, which sensitized against the quinone toxicity. These results suggest the presence of a negative feedback loop exacerbating the quinone toxicity in rat endothelial cells. © 2011 Informa UK, Ltd.

    Novel N3-substituted 9,10-Phenanthrenequinone thiosemicarbazones and their copper, nickel and palladium complexes are structurally characterized and reported along with the single crystal X-ray structures of three ligands and one nickel complex. All compounds were evaluated for their antiproliferative potential against Triple Negative Breast Cancer (TNBC) cells which have poor prognosis and no effective drugs to treat with. All compounds exhibited antiproliferative activity against these cells. Among the metal complexes evaluated, redox active copper complexes were found to be more potent. The possible mechanism for such enhanced activity can be attributed to the generation of oxidative stress, which was amenable for targeting through metal complexation.

    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.

  18. Isolation and characterization of 2-hydroxy-9,10-anthraquinone from Streptomyces olivochromogenes (ERINLG-261 with antimicrobial and antiproliferative properties

    Full Text Available Abstract Currently Streptomyces is one of the most important antibiotic producing microorganisms against several diseases. In the present study Streptomyces olivochromogenes ERINLG-261 was isolated from the soil samples of the Mudumalai hills, Western Ghats, India. Morphological, physiological, biochemical and 16S rRNA studies strongly suggested that this isolate belonged to the genus Streptomyces. ERINLG-261 showed good antimicrobial activity against different bacteria and fungi in Micromonospora fermentation medium. The active ethyl acetate extract was packed in column chromatography over silica gel which led to the isolation of 2-hydroxy-9,10-anthraquinone as the active principle. The isolated compound showed good antimicrobial activity against tested bacteria and fungi in minimum inhibitory concentration (MIC and minimum bactericidal concentration (MBC studies. The compound showed moderate in vitro antiproliferative activity against A549 and COLO320 cells. The compound was subjected to molecular docking studies for the inhibition of Topoisomerase, TtgR and Beta-lactamase enzymes which are targets for antimicrobials. Docking results of the compound showed low docking energy with these enzymes indicating its usefulness as antimicrobial agent. This is the first report of antimicrobial and antiproliferative activity of 2-hydroxy-9,10-anthraquinone isolated from Streptomyces olivochromogenes along with molecular docking studies.

    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)

    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

  5. Master plan study - District heating Sillamaee municipality. Estonia. Final report

    International Nuclear Information System (INIS)

    1997-03-01

    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.. In another scenario - the introduction of natural gas - the town's heat demand will be 530 Tj/p.a. and there will be no heat losses. More detailed studies of environmental impacts should be undertaken

    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.

    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).

    Musty “off-flavor” in pond-cultured channel catfish (Ictalurus punctatus) costs the catfish production industry in the United States at least $30 million 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 μM (125 μg/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 μM 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. PMID:12957919

  14. Expression of conventional and novel glucose transporters, GLUT1, -9, -10, and -12, in vascular smooth muscle cells

    Intimal hyperplasia is characterized by exaggerated proliferation of vascular smooth muscle cells (VSMCs). Enhanced VSMC growth is dependent on increased glucose uptake and metabolism. Facilitative glucose transporters (GLUTs) are comprised of conventional GLUT isoforms (GLUT1–5) and novel GLUT isoforms (GLUT6–14). Previous studies demonstrate that GLUT1 overexpression or GLUT10 downregulation contribute to phenotypic changes in VSMCs. To date, the expression profile of all 14 GLUT isoforms has not been fully examined in VSMCs. Using the proliferative and differentiated phenotypes of human aortic VSMCs, the present study has determined the relative abundance of GLUT1–14 mRNAs by quantitative real-time PCR analysis. Twelve GLUT mRNAs excluding GLUT7 and GLUT14 were detectable in VSMCs. In the proliferative phenotype, the relative abundance of key GLUT mRNAs was GLUT1 (∼43%) > GLUT10 (∼26%) > GLUT9 (∼13%) > GLUT12 (∼4%), whereas in the differentiated phenotype the relative abundance was GLUT10 (∼28%) > GLUT1 (∼25%) > GLUT12 (∼20%) > GLUT9 (∼14%), together constituting 86–87% of total GLUT transcripts. To confirm the expression of key GLUT proteins, immunoblot and immunocytochemical analyses were performed using GLUT isoform-specific primary antibodies. The protein bands characteristic of GLUT1, -9, -10, and -12 were detected in VSMCs in parallel with respective positive controls. In particular, GLUT1 protein expression showed different molecular forms representative of altered glycosylation. While GLUT1 protein displayed a predominant distribution in the plasma membrane, GLUT9, -10, and -12 proteins were mostly distributed in the intracellular compartments. The present study provides the first direct evidence for GLUT9 and GLUT12 expression in VSMCs in conjunction with the previously identified GLUT1 and GLUT10. PMID:23302780

    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.

Considering the X-ray bond parameters, EPR spectra and the atomic spin densities obtained from the density functional theory (DFT) calculations, is defined as a PIQ˙(-) (average C-O/N and C-C lengths, 1.280(2) and 1.453(3) Å) complex of ruthenium(ii) while is a neutral PIQ (average C-O, C-N, C-C and C-O/N lengths, 1.248(7), 1.284(7), 1.485(8) and 1.266(7) Å) complex of the ruthenium(iii) ion. The single crystal X-ray bond parameters proposed that (+)I3(-) (average C-O/N and C-C lengths, 1.294(8) and 1.449(9) Å) and (average C-O/N and C-C lengths, 1.289(2) and 1.447(4) Å) are PIQ˙(-) complexes of ruthenium(iii), while the (+) ion (average C-O/N and C-C lengths, 1.288 ± 0.004 and 1.450 ± 0.017 Å) is a co-facial bi-octahedral complex of ruthenium(iii). In contrast, the (+) ion is a PQ complex of the ruthenium(iii) ion. EPR spectra and the calculated atomic spin densities authenticated that the (+) ion obtained after constant potential coulometric oxidation of is a PIQ complex of ruthenium(iii), while the (-) ion is a hybrid state of [Ru(II)(PIQ˙(-))] and [Ru(III)(PIQ(2-))] states. It is observed that the PIQ˙(-) state in which spin is more localized on the nitrogen (∼38% in and ∼35% in (-) ion) is stable and the coordination of the PIQ(2

    9,10-Phenanthrenequinone (PQ) supported on graphite powder by adsorption was dispersed in propyltrimethoxysilane-derived gels to yield a conductive composite which was used as electrode material to fabricate a PQ-modified carbon ceramic electrode. In this configuration, PQ acts as a catalyst, graphite powder guarantees conductivity by percolation, the silicate provides a rigid porous backbone, and the propyl groups endow hydrophobicity and thus limit the wetting region of the modified electrode. Square-wave voltammetry was exploited to investigate the pH-dependent electrochemical behavior of the composite electrode and an almost Nernstian response was obtained from pH 0.42 to 6.84. Because the chemically modified electrode can electrocatalyze the reduction of iodate in acidic aqueous solution (pH 2.45), it was used as an amperometric sensor for the determination of iodate in table salt. The advantages of the electrode are that it can be polished in the event of surface fouling, it is simple to prepare, has excellent chemical and mechanical stability, and the reproducibility of surface-renewal is good.

    The effects of adrenochrome, a metabolite of epinephrine (adrenaline), and 9,10-phenanthrenequinone (PQ), a component of diesel exhaust particles, on the stereoselective reduction of 4-benzoylpyridine (4-BP) were examined in pig heart cytosol. PQ was a potent inhibitor for the 4-BP reduction, while adrenochrome was a poor inhibitor. A similar result was observed in the effects of adrenochrome and PQ on the reduction of all-trans retinal. Furthermore, although PQ mediated efficiently the formation of superoxide anion radical through its redox cycling in pig heart cytosol, adrenochrome had no ability to mediate the superoxide formation. These may be because the reactivity for adrenochrome, catalyzed by pig heart carbonyl reductase (PHCR), is much lower than that for PQ. The optimal pH for the reduction of PQ in pig heart cytosol was around 5.5. Dicumarol, a potent inhibitor of DT-diaphorase, had little effect on the time course of NADPH oxidation during the reduction of PQ. Therefore, it is concluded that PHCR plays a critical role in superoxide formation through redox cycling of PQ.

    9,10-Phenanthrenequinone (PQ) is harmful environmental pollutant that is detected in airborne particulates. The measurement of PQ in the air should be necessary to evaluate the potential adverse effects of PQ on human health. We have recently developed a determination method for PQ based on the fluorescence derivatization of PQ using benzaldehyde and ammonium acetate as a reagent. In this study, in order to obtain more sensitive and selective fluorescence derivatization reaction, we measured the fluorescence of the reaction mixture of PQ with 21 kinds of aromatic aldehydes in the presence of ammonium acetate. Among the tested aldehydes, 4-carbomethoxybenzaldehyde was found to be the best reagent in regard to fluorescence intensity and emission wavelength maximum. Based on the fluorescence derivatization with 4-carbomethoxybenzaldehyde, a highly sensitive chromatographic method was developed for the determination of PQ with the detection limit (S/N=3) of 1.2 fmol/injection.

    The degradation intermediates of phenanthrene (PHE) may have increased health risks to organisms than PHE. Therefore, environmental fate and risk assessment studies should take into considerations of PHE degradation products. This study compared the sorption properties of PHE and its degradation intermediates, 9,10-phenanthrenequinone (PQN) and 9-phenanthrol (PTR) in soils, sediments and soil components. A relationship between organic carbon content (f(OC)) and single-point sorption coefficient (logK(d)) was observed for all three chemicals in 10 soils/sediments. The large intercept in the logf(OC)-logK(d) regression for PTR indicated that inorganic fractions control PTR sorption in soils/sediments. No relationship between specific surface area and K(d) was observed. This result indicated that determination of surface area based on gas sorption could not identify surface properties for PHE, PQN, and PTR sorption and thus provide limit information on sorption mechanisms. The high sorption and strong nonlinearity (low n values) of PTR in comparison to PHE suggested that the mobility of PTR could be lower than PHE. Increased mobility of PQN compared with PHE may be expected in soils/sediments because of PQN lower sorption. The varied sorption properties of the three chemicals suggested that their environmental risks should be assessed differently. Copyright © 2011 Elsevier Ltd. All rights reserved.

    The nuclear charge radii of $^{7,9,10,11}$Be have been determined by high-precision laser spectroscopy. On-line measurements were performed at ISOLDE with collinear laser spectroscopy in the $2s_{1/2} \\to 2p_{1/2}$ transition of Be$^{+}$. Simultaneous measurements in collinear and anti-collinear direction combined with absolute frequency determination using a frequency comb yielded accuracy in the isotope shift measurements of better than 1 MHz. Combined with accurate calculations of the mass-dependent isotope shifts the nuclear charge radii along the isotopic chain were extracted. The charge radius decreases from $^7$Be to $^{10}$Be and then increases for the halo nucleus $^{11}$Be. When comparing our results with predictions of {\\it ab-initio} nuclear structure calculations we find good agreement. Additionally, the nuclear magnetic moment of $^7$Be was determined to be 1.3998(15) $\\mu_{\\rm N}$ and that of $^{11}$Be was confirmed with an accuracy similar to previous $\\beta$-NMR measurements.

    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.

    A simple and sensitive spectrofluorometric method was developed for the quantitative determination of some beta-blockers, namely arotinolol, atenolol and labetalol as hydrochloride salts. The method is based on the reaction of these drugs as n-electron donors with the fluorogenic reagent 9,10-dimethoxy-2-anthracene sulfonate (DMAS) as pi-acceptor in acidic medium. The obtained ion-pairs were extracted into chloroform and measured spectrofluorometrically at 452 nm after excitation at 385 nm. The fluorescence intensity-concentration plots are rectilinear over the ranges of 0.5-5 microg x ml(1), 1.0-11.0 microg x ml(1) and 0.6-6.4 microg x ml(1) for labetalol, atenolol and arotinolol, respectively. The different parameters affecting the reaction pathway were thoroughly studied and optimized. No interference was observed from the common pharmaceutical excipients. The proposed method was successfully applied to the analysis of tablets and the results were statistically compared with those obtained by reference methods. The method was further extended to the in vitro determination of the drugs in spiked human plasma, the % recoveries (n = 3) ranged from 96.98 +/- 1.55 to 98.28 +/- 2.19. A proposal of the reaction pathway was postulated.

    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.

  1. 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.

    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.

    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.

    Persistent inhalation of diesel exhaust particles results in damaged lung cells through formation of reactive oxygen species (ROS), but the details of the toxicity mechanism against monocytes are poorly understood. In this study, we used human promyelomonocytic U937 cells as surrogates of monocytes and investigated the toxicity mechanism initiated by exposure to 9,10-phenanthrenequinone (9,10-PQ), a major quinone component in diesel exhaust particles. A 24-h incubation with 9,10-PQ provoked apoptotic cell death, which was due to signaling through the enhanced ROS generation and concomitant caspase activation. Flow cytometric analyses of U937 cells after long-term exposure to 9,10-PQ revealed induction of differentiation that was evidenced by increasing expression of CD11b/CD18, a cell-surface marker for monocytic differentiation into macrophages. The 9,10-PQ-induced differentiation was significantly abolished by ROS inhibitors, suggesting that ROS generation contributes to cell differentiation. The 9,10-PQ treatment increased the expression of aldo-keto reductase (AKR) 1C3, which reached a peak at 1 to 2 d post-treatment and then declined. The bell-shaped curve of the AKR1C3 expression by 9,10-PQ resembled that caused by phorbol 12-myristate 13-acetate, a differentiation inducer. Additionally, the concomitant treatment with tolfenamic acid, a selective AKR1C3 inhibitor, sensitized the differentiation induced by 9,10-PQ. These results suggest that ROS formation during 9,10-PQ treatment acutely leads to apoptosis of U937 cells and the initiation of monocytic differentiation, which proceeds after the provisional overexpression of AKR1C3.

    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.

    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

    Illegal drug use and HIV are independent risk factors for tuberculosis (TB) among injecting drug users (IDU). Estonia and Latvia have experienced high rates of TB as well as IDU and HIV outbreaks. There is a lack of knowledge about TB among IDUs in these countries. The purpose of the current study was to estimate the prevalence and risk factors of Mycobacterium tuberculosis (MTB) infection among IDUs in Estonia and Latvia. Participants for this cross-sectional study were recruited from syringe exchange programmes using respondent-driven sampling. For assessing infection with MTB interferon-gamma release assay (IGRA) was used. The study included 375 participants from Estonia and 313 from Latvia. The prevalence of IGRA-positivity among IDUs was 7.7% in Estonia and 25.6% in Latvia. HIV-prevalence was 62% in Estonia and 23% in Latvia. In both countries, IGRA-positivity rates did not differ between HIV-positive and HIV-negative participants. IGRA-positivity was independently associated with a prior diagnosis of TB in Estonia and with imprisonment (ever within a lifetime) and preceding contact with a TB patient in Latvia. Our findings indicate there is an urgent need for a more vigorous approach in providing IDUs with TB screening services. Copyright © 2013 Elsevier B.V. All rights reserved.

    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.

    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.

    9,10-Phenanthrenequinone (9,10-PQ) is one of the most abundant quinones among diesel exhaust particulates. Recent data have suggested that quinones induce apoptosis in immune, epithelial and tumor cells, leading to respirator illness; however, the mechanisms by which quinones induce apoptosis and the structure required for this remain unknown. We studied the antitumor activity of 9,10-PQ analogs against two human tumor cell lines, HCT-116 colon tumor cells and HL-60 promyelocytic leukemia cells. The loss of the cis-orthoquinone unit in 9,10-PQ abrogated its ability to induce apoptosis in the two tumor cell lines, and the LC50 values of these analogs were indicated over 10 μM. An analog of 9,10-PQ in which the biaryl unit had been deleted displayed a reduced ability to induce tumor cell apoptosis, while the analogs 1,10-phenanthroline-5,6-dione (9) and pyrene-4,5-dione (10), which also had modified biaryl units, exhibited increased tumor cell apoptotic activity. The cis-orthoquinone unit in 9,10-PQ was identified as essential for its ability to induce apoptosis in tumor cells, and its biaryl unit is also considered to influence orthoquinone-mediated apoptotic activity.

    9,10-Phenanthrenequinone (PQ), a major quinone component in diesel exhaust particles, is considered to provoke damage of respiratory and vascular cells through highly producing reactive oxygen species (ROS), but little is known about its pathophysiological role in neuronal cell damage. In this study, we found that incubation with 1,2-naphthoquinone, 1,4-naphthoquinone and PQ, major quinone components in diesel exhausts, provokes apoptosis of human neuroblastoma cell lines. SK-N-SH cell treatment with a lethal concentration of PQ facilitated ROS production within 6 h. The treatment also promoted formation of 8-hydroxy-deoxyguanosine, p53 activation, elevation of Bax/Bcl-2 ratio, lowering of mitochondrial membrane potential, and resultant activation of caspase-9 and caspase-3, inferring that ROS production, DNA damage and mitochondrial dysfunction are crucial processes of the PQ-triggered SK-N-SH cell apoptosis. The PQ treatment of SK-N-SH cells elevated the level of 4-hydroxynonenal (HNE), a cytotoxic reactive aldehyde generated from lipid peroxidation. The treatment with PQ and HNE also decreased cellular levels of total and reduced glutathiones, and the damage elicited by HNE was ameliorated and deteriorated by pretreating with cell-permeable glutathione analog and the depletor, respectively. Moreover, the treatment with PQ and HNE decreased the proteasomal proteolytic activities, suggesting a contribution of decrease in the antioxidant abilities to the ROS-mediated neuroblastoma cell apoptosis. Our comparative analyses of 17 cells showed a positive correlation between the PQ reductase and NAD(P)H:quinone oxidoreductase 1 (NQO1) activities. In addition, overexpression and knockdown of NQO1 augmented and lowered, respectively, the ROS production through PQ redox-cycling and the quinone toxicity. Furthermore, the treatment with PQ and HNE up-regulated the NQO1 expression. Taken together, PQ exposure produces large amounts of ROS in neuroblastoma cells via NQO1 up

    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

    Full Text Available The Natura 2000 network contains many different habitats in Estonia, including old-growth forests and semi-natural woodlands. Ten years after the establishment of the Natura 2000 network in Estonia, changes have occurred in habitat type and habitat quality. Vegetation composition as well as the structural and functional qualities of a forest habitat type – Fennoscandian herbrich forests with Picea abies (EU Habitats Directive habitat type 9050 – are analysed in this study. The study is based on sample plots measured in 2014 and are located in protected and non-protected areas. Aegopodium, Filipendula and Oxalis vegetation types are included for assessment of vegetation, tree structure and deadwood composition. Habitat composition and dynamics on conservation sites are compared with commercial forests and possible ecosystem restoration measures are discussed in the study. The 46% of the studied habitats had considerably lowered their initial conservation value and 49% were developed towards habitat type 9010 during 2004–2014.

    The sexual revolution and fight for gender equality began in the West during the 1960s but did not reach the Soviet Union until the late 1980s. Using survey data from nationally representative samples from Finland in 1971, 1992, and 1999 and from two former Soviet areas, Estonia in 2000 and St. Petersburg in 1996, we investigated the following: (a) differences across decades and countries in acceptance of the sexual double standard (SDS) in attitudes toward marital infidelity and women's initiating sex; and (b) the relationship between the SDS and sexual satisfaction. Results show that Finland in the 1990s was more egalitarian than Finland in 1971, St. Petersburg in 1996, or Estonia in 2000. Egalitarian sexual attitudes were positively related to sexual satisfaction.

    2013-01-01

    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 This paper assesses the success of an innovative national e-participation project in Estonia. To carry out this task, the paper combines quantitative (aggregate user data, content analysis via tagging and qualitative (individual user survey and interviews with public officials data analysis. 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.

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

    Directory of Open Access Journals (Sweden)

    Mart HIOB

    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.

    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)

    Laine, M; Niin, E; Pärtel, A

    2008-01-01

    The first case of sylvatic rabies in Estonia was recorded in 1968. Rabies is maintained in raccoon dogs and red foxes. The main prophylactic means used in animals up to 2005 consisted of compulsory vaccination of dogs and cats. In October 2005, the first large scale wildlife oral vaccination campaign was carried out in the northern part of the country (25,800 km2) from the western to the eastern border, including islands. In 2006, two campaigns were conducted across the country. Rabies surveillance and the efficacy of oral vaccination were assessed by a follow-up of rabies incidence and bait consumption (tetracycline examination). As a result, the number of rabies cases decreased drastically in 2005 and 2006 with a total of 266 and 114 animal cases, respectively. These results will be discussed in the context of rabies epidemiological surveillance in Estonia and in Europe.

  15. 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.

    Full Text Available Late Pridoli Cruziana traces have recently been found in carbonate shelf sediments of the Ohesaare Formation on Saaremaa Island, Estonia. Cruziana isp. is interpreted here as a locomotory trace (repichnia of an arthropod, possibly a trilobite. Cruziana traces previously known from the Silurian of Baltica differ from Cruziana isp., indicating that the diversity of Cruziana traces in the late Silurian of Baltica was higher than previously thought.

    Reactions of 9,10-phenanthrenequinone (PQ) in toluene with [M(II)(PPh3)3X2] at 298 K afford green complexes, trans-[M(PQ)(PPh3)2X2] (M = Ru, X = Cl, 1; M = Os, X = Br, 2) in moderate yields. 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. Single crystal X-ray structure determinations of 1·2toluene, 2·CH2Cl2 and 4(+)I3(-), UV-vis/NIR absorption spectra, EPR spectra of 3, electrochemical activities and DFT calculations on 1, 2, trans-[Ru(PQ)(PMe3)2Cl2] (1Me), trans-[Os(PQ)(PMe3)2Br2] (2Me), cis-[Rh(PQ)(PMe3)2Cl2] (3Me) and their oxidized and reduced analogues including trans-[Os(PQ)(PMe3)2(CO)(Br)](+) (4Me(+)) substantiated that 1-3 are the 9,10-phenanthrenesemiquinone radical (PQ(˙-)) complexes of ruthenium(III), osmium(III) and rhodium(III) and are defined as trans/cis-[M(III)(PQ(˙-))(PPh3)2X2] with a minor contribution of the resonance form trans/cis-[M(II)(PQ)(PPh3)2X2]. 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

    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 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.

    The aim of this study was to examine past mammography use and mode of detection among breast cancer (BC) patients in Estonia, a country that has low screening coverage and high BC mortality. Women newly diagnosed with primary BC in Estonia in 2008-2010 were interviewed. Determinants of past mammography use and the detection of BC by mammography were studied using multivariate logistic regression. Among 977 participants, almost half reported no mammograms prior to the detection of BC. Overall, 22% of the cases were detected by mammography (16% by screening mammography). Detection by mammography was strongly related to age, past mammography use, and obesity. Among cases detected by mammography, 10% were stage III/IV at diagnosis (32% among cases detected by other modes). This study showed low mammography utilization and high rate of self-detection of BC in Estonia. Increased detection by mammography would help diagnose the disease at an earlier stage and consequently avoid premature BC deaths. Efforts should be undertaken to increase participation in screening and improve the availability of mammography among older and high-risk women. The results are likely to be relevant for other countries and population groups with low screening coverage.

    Time series of monthly, seasonal and annual mean air temperature, precipitation, snow cover duration and specific runoff of rivers in Estonia are analysed for detecting of trends and regime shifts during 1951-2015. Trend analysis is realised using the Mann-Kendall test and regime shifts are detected with the Rodionov test (sequential t-test analysis of regime shifts). The results from Estonia are related to trends and regime shifts in time series of indices of large-scale atmospheric circulation. Annual mean air temperature has significantly increased at all 12 stations by 0.3-0.4 K decade-1. The warming trend was detected in all seasons but with the higher magnitude in spring and winter. Snow cover duration has decreased in Estonia by 3-4 days decade-1. Changes in precipitation are not clear and uniform due to their very high spatial and temporal variability. The most significant increase in precipitation was observed during the cold half-year, from November to March and also in June. A time series of specific runoff measured at 21 stations had significant seasonal changes during the study period. Winter values have increased by 0.4-0.9 L s-1 km-2 decade-1, while stronger changes are typical for western Estonia and weaker changes for eastern Estonia. At the same time, specific runoff in April and May have notably decreased indicating the shift of the runoff maximum to the earlier time, i.e. from April to March. Air temperature, precipitation, snow cover duration and specific runoff of rivers are highly correlated in winter determined by the large-scale atmospheric circulation. Correlation coefficients between the Arctic Oscillation (AO) and North Atlantic Oscillation (NAO) indices reflecting the intensity of westerlies, and the studied variables were 0.5-0.8. The main result of the analysis of regime shifts was the detection of coherent shifts for air temperature, snow cover duration and specific runoff in the late 1980s, mostly since the winter of 1988

    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.

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

  16. 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. Copyright © 2012 Elsevier Inc. All rights reserved.

    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.

    2012-04-01

    Full Text Available From the beginning of the 20th century on, the activities of the Young Estonia literary movement have had a significant influence on the development of Estonian culture. The group published five Young Estonia albums (1905–1915, the magazine Young Estonia, devoted to science, literature, and the arts (1910– 1911, and the newspaper Vaba Sõna (1914–1916, Free Word. The core of the group was composed of five or six active writers who maintained lively interactions with art and theatre circles. The publications of the Young Estonia Press brought about a revolutionary turn in the design and printing styles of the Estonian-language book. The questions of Young Estonia’s role and meaning have intrigued the Estonian cultural public at different times and in different ways. Young Estonia brought to cultural consciousness liberal views on the interpretation of art as well as an elitist aesthetics. At different times their openness to Europe irritated both the nationalist-minded and internationalists; thus the reception of the Young Estonia movement has been polemical throughout Estonian cultural history. Elapsed time has both opened the way for broader generalizations and, conversely, created a need to reconstruct the cultural context of the beginning of the 20th century. Polemic around Young Estonia was certainly caused by the group as a whole; however, in this article the role of individual members is also highlighted. It is emphasized that the political and aesthetic ideas of the Young Estonians changed synchronously with social conditions, from the 1905 Russian revolution to the world war that ravaged Europe. If the early part of this period saw a more social and nationalist bent to their thinking, then in the years of reaction, positions were taken that were more in keeping with l’art pour l’art. Young Estonia was not a hierarchical organization; rather, its small core group was composed of a narrow circle of friends with various

    Full Text Available Young Estonia persists in Estonian cultural memory as a movement of renewal, among other factors through its impetus to the development of urban culture. 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. (4 Futurism and film. Young Estonia’s later period coincided with the intensive use of term ”futurism” in Estonian journalism. Young

  5. Impact of rapid socio-economic changes on teenage pregnancies in Estonia during 1992-2001.

    Major socio-economic changes, including health care reforms and changes in the school curriculum, took place in Estonia after the country regained its independence in 1991. These changes affected people's reproductive behavior in many ways. In this article, the impact of the changes on the reproductive behavior of teenage girls, measured by adolescent fertility and abortion rates between 1992 and 2001, is analyzed. National data on abortions and births were obtained from official medical statistics, particularly from the Estonian Abortion Registry and the Estonian Medical Birth Registry. Female population denominators for the age group 15-19 were obtained from the Statistical Office of Estonia. In teenagers, the birth rate decreased more than two times, from 49.7 per 1000 in 1992 to 23.8 per 1000 in 2001. The abortion rate per 1000 decreased from 55.5 in 1992 to 30.4 in 2001. Compared with all women of fertile age (15-49 years), at the beginning of the decade, teenagers decided more often to have a baby, and, at the end of the decade, they decided more often to terminate the pregnancy. Two-thirds of all pregnancies in teenagers end in abortion--either legally induced abortion (legal abortion and therapeutic abortion) or spontaneous abortion. In 2001, the abortion ratio was 116.4 among ethnic Estonians and 147.9 among non-Estonians. The case in Estonia again proves that the availability of information, contraceptives, services and education, and the existence of other goals in life besides childbearing, have an impact on teenage birth and abortion rates. Successful health promotion activities should take into consideration the differences in the reproductive behavior of different ethnic groups.

  6. Age-specific cancer survival in Estonia: recent trends and data quality.

    A number of population-based studies have demonstrated lower cancer survival in elderly patients than among middle-aged or younger patients. Also, data quality in cancer registries has been shown to be associated with age. The objective of this study was to examine the recent age-specific cancer survival trends and age-specific quality of cancer data in Estonia. Using Estonian Cancer Registry data, we calculated relative survival ratios (RSRs) for eight common cancers in Estonia in 1995-1999 (cohort method) and 2005-2009 (period method) for four major age groups (15-54, 55-64, 65-74, and 75-84 years at diagnosis). The main data quality indicators were calculated, and the age-specific effect of missing death certificate initiated (DCI) cases on survival was estimated comparing 5-year RSRs computed from the complete data set with those from data set without DCI cases. We observed overall rise in 5-year RSR for all eight cancers over the study period, with a considerable variation by age, with the lowest survival among the oldest patients. The widest age gradient in 5-year RSR was seen for bladder cancer (20% units in 2005-2009), followed by cancers of lung (16% units), kidney (15% units), breast and prostate (13% units), stomach and rectum (11% units), and colon (5% units). All data quality indicators, including proportion of cases with unknown stage showed a similar age-related pattern with the lowest quality in the oldest age group. The effect of missing DCI cases on survival estimates increased by age and was around 3% units for prostate and kidney cancers among the oldest patients. Young or middle-aged patients in Estonia experienced larger survival gain since the late 1990s than elderly patients. Decreasing quality of cancer registry data along with increasing patient age suggests less thorough clinical investigations in older age groups.

    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

    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.

    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)

    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)

    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.

    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)

    We present our studies on the photopolymer of poly(methyl methacrylate) (PMMA) doped with 9,10-phenanthrenequinone based derivatives for volume holographic storage. By introducing different functional groups on the side-chain of 9,10-phenanthrenequinone molecule, the holographic characteristics of the material can be modified. The photoreaction involved with the holographic recording in the samples was investigated by measuring UV-Vis absorption spectrum and mass spectrum. The experimental results show that the similar behaviors were exhibited in these photopolymers. It is found that phase hologram recording in our PQ derivatives doped PMMA photopolymer involves a structure change of the quinone based molecule, which induces a strong change of the refractive index. Experimental characterizations on holographic data storage, including material sensitivity, dynamic range ( M#) and bit-error-rate have been performed. We found that, by selecting appropriate functional groups, an improvement in sensitivity and M# for holographic data storage can be achieved.

Students of either sex, aged between 16 and 19 years and entering grade 10, 11 or 12 during the 2005-2006 school year participated in a cross sectional survey. A structured questionnaire was administered to a convenience sample of students from selected schools in Belgium, the Czech Republic, Estonia and Portugal. In each country, more than three quarters of respondents had previously had a boyfriend or girlfriend and almost half had heterosexual intercourse. More than 85% of sexually experienced youths in each country had used contraception at coital debut. Mean age at coital debut varied between 15.2 (Belgium) and 16.4 years (Czech Republic). While 51% of respondents in Estonia knew of Chlamydia trachomatis infection, the corresponding figure in Portugal was only 12%. Sexual activity is common among school-going youths in all four countries. This highlights the need for Member States to systematically collect indicators of SRH in this population. Use of a common measurement framework can inform the establishment of common targets for joint initiatives such as reducing teenage pregnancy and STIs in adolescents.

    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.

  3. Application of OSL and 10Be techniques to the establishment of deglaciation chronology in Estonia

    The deglaciation history of Estonia has been under research for about a century. Despite the great number of publications devoted to this subject and marked improvements in study methods, many problems of topical interest have not been solved yet, especially due to the lack of good direct dating methods. In this paper the suitability of OSL and 10 Be dating techniques for establishing accurate deglaciation chronology for Estonia is assessed. Turbidity and water depth, velocity of outwash streams and transport length, possible fast sedimentation at night hours or below the ice, incorporation of older, unbleached particles, and other factors affected the extent of the bleaching of the TL signal in different ways, causing great variability of dates. Surface inclination, height of the surface over ground, snow and vegetation cover, and evolution of water bodies influenced the calculation of reliable exposure ages of objects dated using the 10 Be method. It means that age determinations of both glaciofluvial deposits with the OSL method and erratic boulders with the 1B e method are highly problematic, especially for glaciofluvial intertill sediments where the exact genesis of deposits is unknown and for boulders, which have been in the forest, under the waters of proglacial lakes and/or the Baltic Sea, or under snow cover for a long time.

    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 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.

    Full Text Available The aim of the present article is to outline some of the basic characteristics of the post-Soviet ‘renaissance’ of the Estonian Apostolic Orthodox Church (under jurisdiction of the Ecumenical Patriarchate of Constantinople, for example the conversion from Lutheranism to Orthodox Christianity and the processes of rediscovery, reinvention and ‘Estonianisation’ of Orthodox Christianity. The restoration of the autonomous Estonian Apostolic Orthodox Church, beginning in the 1990s, is due to the historic presence of Orthodoxy in Estonia, but also has the particularities of a new project that seeks contemporary horizons and copes with specific postsocialist problems. The paper takes a closer look at the specific dimensions of these processes through a study of a small Orthodox community: the parish of St. Alexander Nevsky church in Tartu. The author strives to demonstrate the living process of reinvention of Orthodox Christianity in Estonia and more generally the ‘making’, creation, of religion. The small religious community in Tartu dealt with in the paper, shares a number of features of the transforming religiosity of Europe: emphasis on spirituality, openness to the impacts of globalisation, the hybrid character of certain religious practices. It is likewise an example of the fact that Orthodox Christianity may also be the free choice of people looking for moral perfection. This is one of the answers to the main research question about the reasons and character of a contemporary conversion to Orthodox Christianity.

    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.

    In this cross-sectional study, we investigated veterinarians in Estonia for evidence of exposure to hepatitis E virus (HEV). In 2012, we collected sera from 158 persons attending a veterinary conference, of whom 156 completed a questionnaire covering their background information. Altogether 115 persons reported they had obtained a veterinary degree and were included in this study. The sera were tested for presence of antibodies against HEV using a commercial enzyme linked immunosorbent assay and a commercial immunoblot assay in series. A sample was considered antibody-positive if it tested positive with both tests. Antibody-positive samples were further examined for the presence of HEV RNA. Three (2.6%) of the 115 veterinarians tested positive for immunoglobulin G antibodies against HEV, whereas no immunoglobulin M antibodies against the virus were detected. The antibody-positive veterinarians were small animal practitioners. Pigs comprised no or small part of their working time or patients. No HEV RNA was detected in the antibody-positive samples. The prevalence of antibodies against HEV in veterinarians in Estonia was lower than what has been observed in veterinarians in other countries.

  11. Post-Comunist Development of Administrative Structure in Estonia: From Fragmentation to Segmentation

    2011-12-01

    Full Text Available The article focuses on the issue of administrative structure and its development in a postcommunist context. The case of the Estonian administrative system is analyzed. The article aims to find out how and why a decentralized administrative structure has formed in Estonia. To fulfill this aim, the current organizational landscape of the Estonian public administration is described and its trajectories of development over the 20-year period are discussed. The analytical framework of the article draws on organization theory and literature on post-communist transition. It is found that during the 20 years of regained independence, factors have combined in favor of specialization over coordination in Estonia. First, the aim of overthrowing the legacy of centralized soviet public administration in combination with pressures of transition and the sectoral character of the EU accession process have contributed to the development of a public administration with strong ministries having a considerable leverage over the issues falling to their areas of governance. Second, the neo-liberal worldview of Estonia’s politico-administrative elite and its inclination towards a lean state and down-sizing have led to reluctance towards investing into coordinating functions and administrative development more generally.

    The aim of the study was to describe trends in alcoholic liver cirrhosis mortality rates in 1992-2008 and to examine socio-demographic differences in alcoholic liver cirrhosis mortality. Individual records of deaths from alcoholic liver cirrhosis among 25-64-year olds in 1992-2008 in Estonia were analysed. Age-standardized mortality rates for men and women aged 25-44 and 45-64 were calculated. Association between alcoholic liver cirrhosis mortality and socio-demographic variables (age, education and ethnicity) for the data of the years around the census in 2000 was measured by mortality rate ratios using Poisson regression models. In 1992-2008, alcoholic liver cirrhosis mortality rates were higher among men than that in women and that in the older than in the younger age group. Over the whole study period, mortality from alcoholic liver cirrhosis increased steeply. The increase was sharper among men and women in the older age group. In 1998-2001, higher alcoholic liver cirrhosis mortality rates occurred in non-Estonians and those with lower levels of education. Alcoholic liver cirrhosis mortality has increased steadily in Estonia, and is reflected in an increase in heavy drinking. National alcohol policies should address all strata of society. However, in order to reduce alcohol-related damage in the population most effectively, special attention should be paid to non-Estonians and people with low levels of education.

The aim of the present study was to examine the course of PTS up to three years after losing relatives in the MS Estonia ferry disaster, one of the worst maritime disasters in modern times.Seven postal surveys were sent out over three years post-disaster. The respondents were invited and added consecutively during the three years and 938 relatives participated in one or more of the surveys, representing 89% of the MS Estonia's Swedish victims. The survey included the Impact of Event Scale (IES to measure PTS. Latent growth curve modeling was used to analyze PTS over time.The majority of bereaved individuals had high levels of PTS. At three years post-loss, 62% of the respondents scored above the recommended cut-off value on the IES. Over time, PTS symptoms declined, but initially high symptoms of PTS were associated with a slower recovery rate.The present finding suggests that being an indirectly-exposed disaster-bereaved close-relative can lead to very high levels of PTS which are sustained for several years.

    Full Text Available Education is one of the most important determinants of socio-economic success in modern societies, but educational inequality remains an important societal problem. The aim of this study was to look at public attitudes towards the value of education and views on the opportunities to access education in Estonia. Using data from the Estonian Social Equality and Inequality Study (2010, the findings of the current study suggested that education is highly valued in Estonia, but the public also tends to think that access to education is not equally available to everybody. Furthermore, we found that there is a social-status-based structure in the views of the value of education and access to education. Lower social status groups tend to value education as less important for success in life, and these lower social status groups are also more likely to think that chances to access higher education are not equal for everybody, but that wealth, gender, ethnicity and social status matter. Similarly, inequality of opportunity is also felt more strongly within the ethnic minority group, the non-Estonians, than it is amongst Estonians.

    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?

    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.

The first acid dissociation constants for the reduced semiquinones were measured as pK{sub a} = 3.65 and 3.95 for 1,5-DHAQ and 1,8-DHAQ, respectively. Second-order rate constants for various formation and decay reactions have been determined. The one-electron reduction potentials (vs. NHE) were determined at pH 11, as E{sub 11}{sup 1} = -350 mV (for 1,5-DHAQ) and E{sub 11}{sup 1} = -377 mV (for 1,8-DHAQ), respectively. Differences with 1,4-dihydroxy-9,10-anthraquinone (quinizarin) are discussed. (author).

The experiment involved a total of 325 Akhal-Teke horses; 121 horses came from the Czech Republic, 152 were from Russia, 28 were from Estonia and 24 horses came from Switzerland. For the divided database of micro satellites we evaluated the following parameters: effective number of alleles, frequency of alleles for the groups of horses; the observed heterozygosity (HO; the expected heterozygosity (HE; the inbreeding coefficient (Fis; and the genetic distance. The researched population is polymorphous. The population in the Czech Republic differs from the other three countries in the numbers of alleles per locus. The Czech population also includes Akhal-Teke horses which are not purebred Akhal-Teke horses. A confirmation of this fact is the effective number of alleles. The population in the Czech Republic exhibits the highest mean number of effective alleles. The Akhal-Teke population in Estonia exhibits the highest mean observed heterozygosity. By contrast, the population in the Czech Republic exhibits the lowest mean observed heterozygosity. In the Czech Republic the mean Fis value is a positive number indicating a reduced number of heterozygotes in the Czech Akhal-Teke population. The genetic distance is the highest between populations of horses bred in Russia and Estonia. The genetic distance is the lowest between populations of Akhal-Teke horses bred in Russia and in the Czech Republic.

    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

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

    Directory of Open Access Journals (Sweden)

    Konsa, M.

    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

    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.

    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

    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.

  4. Age of the Kalana Lagerstätte, early Silurian, Estonia

    Full Text Available The Kalana quarry in central Estonia is known for its exceptionally well-preserved non-calcified algal and other fossils. The interval with the fossil Konservat Lagerstätte in the Kalana section has previously been tentatively dated as early Aeronian. Recent findings of graptolites now enable more precise dating of these beds. The strata yielding the Lagerstätte are not older than the mid-Aeronian and correspond to the Pribylograptus leptotheca graptolite Biozone. In terms of conodont biostratigraphy they correlate with the middle of the Pranognathus tenuis conodont Biozone. It has also become evident that the uppermost Jõgeva Beds of the Nurmekund Formation, and probably also the uppermost Ikla Member of the Saarde Formation, are younger than previously thought and correlate with the Pribylograptus leptotheca graptolite Biozone. Our data additionally indicate that the conodont genus Aulacognathus had appeared by the mid-Aeronian.

    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

    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)

    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.

    HIV and sexually transmitted infections (STI) testing rates among men who have sex with men (MSM) in Estonia are low. We collected data from 265 MSM in a national, online survey. Lifetime HIV testing was related to risky sexual behaviors and contacts with health care services, while lifetime STI testing was related only to contacts with health care services. In addition, some personal values were significant predictors of testing. For example, high achievement (personal success through demonstrating competence according to social standards) had a negative impact on lifetime HIV testing, and high interpersonal conformity (avoiding upsetting others) had a negative impact on lifetime STI testing. The results demonstrate the need to develop gay-friendly health services and to recognize the role of personal values and individual differences in values when designing attractive interventions to increase HIV/STI testing rates among MSM.

    Full Text Available This article reviews the New Public Man-agement (NPM literature in Central and Eastern Europe, looking particularly at reforms in Estonia, Hungary and Romania. It fnds that research that assessed changes in internal processes and ac-tivities within the public sector by far outnumber research that assessed changes in outputs and outcomes. Signifcant challenges in assessing impacts make sweeping claims about whether NPM ‘works’ diffcult to support with solid evi-dence. The paper shows that NPM policy is still considered as an option for public sector mod-ernization in Central and Eastern Europe, and suggests that a number of components of NPM, if not the model as a whole, are likely to contin-ue to exert infuence on the public sector in the future.

    The aim of the present study was to investigate the content of total carotenoids in different collections of pot marigold (Calendula officinalis L.) inflorescences. Commercial seeds (42 samples) of C. officinalis were obtained from nine countries and cultivated in private gardens in three different counties of Estonia. The content of total carotenoids, determined spectrophotometrically (lambda=455 nm) varied in the investigated collections from 0.20 to 3.51%. The amount of pigments may depend on the type of plants, the importing company, the color of the ligulate and tubular florets, and the place and time of cultivation. For medicinal purposes, C. officinalis with brownish-yellow ligulate and tubular florets should be preferred. The best was found to be 'Golden Emperor' from Finland.

    Full Text Available Timothy (Phleum pratense L. is an important agricultural grass in Europe and North America, but there is little research into the occurrence and abundance of fungal endophyte species associated with this grass. The aim of this study was to identify fungal endophytes living within P. pratense and to determine if additional moisture applied during the growing season increases the diversity of endophytic fungi. We studied 58 isolates obtained from surface-sterilised blades of 60 P. pratense plants collected from Rõka Free Air Humidity Manipulation experimental plots (FAHM, Estonia. Morphological and molecular methods were used for isolate identification. As a result, 45 strains from 10 different taxa were identified, all belonging to Ascomycota. Five species were found to be new to P. pratense.

    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.

    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. The system consists of regional Data Banks, imitation model for calculation of pollutants dispersion, common and application programs. (author)

  15. 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.

    2013-06-01

    Full Text Available The history of folkloristics contains many cases of obscene materials that were excluded from field notes, books and archives. The Estonian Folklore Archives (founded in 1927 did incorporate dirty jokes, riddles and songs in its collection. Soviet occupation changed the topics of folklore scholarship and archival practices. Between the years 1945 and 1952, the Folklore Archives’ manuscript collections, catalogues and photographs were censored. Anti-Soviet texts were cut out or made unreadable. In the first years after the incorporation of the Republic of Estonia into the Soviet Union, anti-Soviet mainly meant politically sensitive materials such as jokes about Stalin, very patriotic texts or the names of some people. During the beginning of the 1950s, stricter rules were applied and obscene texts were also censored. In this article, I will focus on the censorship of obscene words and motifs and the political dimension of moralistic censorship in a totalitarian state.

    During southward migration in the years 2006-2009, 178 migratory passerines of 24 bird species infested with ticks were captured at bird stations in Western Estonia. In total, 249 nymphal ticks were removed and analyzed individually for the presence of Borrelia burgdorferi sensu lato (s.l.), tick-borne encephalitis virus (TBEV), and Anaplasma phagocytophilum. The majority of ticks were collected from Acrocephalus (58%), Turdus (13%), Sylvia (8%), and Parus (6%) bird species. Tick-borne pathogens were detected in nymphs removed from Acrocephalus, Turdus, and Parus bird species. TBEV of the European subtype was detected in 1 I. ricinus nymph removed from A. palustris. B. burgdorferi s.l. DNA was found in 11 ticks (4.4%) collected from Turdus and Parus species. Bird-associated B. garinii and B. valaisiana were detected in I. ricinus nymphs removed from T. merula. Rodent-associated B. afzelii was detected in 3 I. ricinus nymphs from 2 P. major birds. One of the B. afzelii-positive nymphs was infected with a mix of 2 B. afzelii strains, whereas 1 of these strains was also detected in another nymph feeding on the same great tit. The sharing of the same B. afzelii strain by 2 nymphs indicates a possible transmission of B. afzelii by co-feeding on a bird. A. phagocytophilum DNA was detected in 1 I. ricinus nymph feeding on a T. iliacus. The results of the study confirm the possible role of migratory birds in the dispersal of ticks infected with tick-borne pathogens along the southward migration route via Estonia.

    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

    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.

    The aim of this study was to evaluate new working conditions in the construction industry in Estonia. Three construction sites were investigated: a dwelling house at the stage of renovation, a warehouse at the stage of excavation and preparation work, and a hotel, where we examined the working conditions of the finishers. Microclimate: air temperature, relative humidity and air velocity were determined at every workplace. Full-shift personal exposure measurements of dust and gas exposure were performed among 97 construction workers in breathing zone air. The concentration of lead in the air was analysed by AAS. Vapours of benzene, styrene and toluene concentrations were determined by gas chromatography. The noise level was measured with the help of the sound-level meter at every workplace. All microclimatic indices were sometimes below or above exposure standards for indoor work. High levels of airborne dust and increased concentrations of lead were observed during repair work. Low concentrations of organic solvents in the air were determined when using paints and some synthetic substances. The noise level exceeded the permitted limit when an excavator and powerful electric appliances were used. A questionnaire determined the prevalence of subjectively experienced musculoskeletal strain in 30% of workers. The working conditions in the construction industry in Estonia are approaching European level. However, it is necessary to improve working conditions permanently by the use of new harmless materials, personal protective equipment, and through influencing worker health by permanent education and medical watch. We consider that questionnaires are very important in the control of the work environment, in subjective health assessments, and as a source of useful proposals to improve working conditions.

  2. Late glacial multiproxy evidence of vegetation development and environmental change at Solova, southeastern Estonia

    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 trophoblast cell line, JEG-3, was used to study the cytotoxicity of phenanthrene, 9,10-phenanthrenequinone (PHEQ), anthracene, and 9,10-anthracenedione alone and with copper. The endpoints were the capacity of cultures to reduce alamar Blue (AB), a measure of energy metabolism, and to convert carboxyfluorescein diacetate acetoxymethyl ester (CFDA AM) to carboxyfluorescein, an indication of membrane integrity. Only PHEQ elicited a cytotoxic response. PHEQ caused a concentration-dependent decline in AB but not in CFDA AM readings, suggesting an impairment to energy metabolism. In the presence of copper, PHEQ concentration-response curves were shifted to the left for AB and were obtained with CFDA AM. The Cu/PHEQ synergy is attributed to an increase in redox cycling and production of reactive oxygen species (ROS), which overwhelm antioxidant defenses, damaging energy metabolism first and then membrane integrity. The impermeable copper chelator, bathocuproine, reduced the PHEQ/copper interaction, but the permeable chelator, neocuproine, and copper together were cytotoxic.

    9,10-Phenanthrenequinone (PQ), is one of the components of diesel exhaust particulates, has potent harmful effects on human health. For the determination of PQ in airborne particulates, a highly sensitive and selective high-performance liquid chromatography (HPLC) method was developed with fluorescence detection following the pre-column fluorescent derivatization. PQ was derivatized with benzaldehyde as a derivatizing reagent in the presence of ammonium acetate to give fluorescent 2-phenyl-1H-phenanthro [9,10-d] imidazole. The maximum fluorescence intensity of the derivative was observed by the reaction with 0.2M benzaldehyde and 0.5 M ammonium acetate at 100 degrees C for 30 min. The HPLC separation of fluorescent derivative of PQ was performed within 20 min on an ODS column with a mixture of acetonitrile-water (55:45, v/v) as a mobile phase. Highly sensitive and selective determination of PQ was attained with the detection limit of 5 fmol (S/N = 3). By the proposed method, PQ in airborne particulates was successfully determined in the range 0.26-0.30 ng/m3 (n = 3).

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

    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.

    The mechanism of action of the diterpenoid 3β-hydroxykaurenoic acid and the anthraquinone 4,4-dimethylanthracene-1,9,10(4H)-trione on the phytopathogenic fungus Botrytis cinerea was studied. The effect of both compounds on the respiratory process and on the membrane integrity of B. cinerea was evaluated. The results showed that 3β-hydroxykaurenoic acid inhibited the growth of this fungus by disrupting the plasmatic membrane. This compound also partially affected oxygen consumption of B. cinerea germinating conidia. Conversely, 4,4-dimethylanthracene-1,9,10(4H)-trione did not produce membrane disruption of B. cinerea. The effect of this compound on mycelial growth was notably increased by the presence of an inhibitor of the cyanide-resistant respiration pathway. It also was shown that the anthraquinone inhibited oxygen consumption by about 80%; therefore this compound would act as a potent inhibitor of the cytochrome pathway of the respiratory chain to exert its antifungal effect. © 2015 by The Mycological Society of America.

    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

    A new series of 9(10H)-acridinone-1,2,3-triazole derivatives were designed, synthesized and evaluated for their cytotoxic activity against human breast cancer cell lines. The acridone skeleton was prepared through the Ullman condensation of 2-bromobenzoic acid and anilines. Subsequently, it was functionalized with propargyl bromide. Then, a click reaction of the latter compound and in situ prepared 1-(azidomethyl)-4-methoxybenzene derivatives led to the formation of the desired triazole products. Finally, all products were investigated for their capability to cause cytotoxicity against MCF-7, T-47D, and MDA-MB-231 cell lines. Among them, 2-methoxy-10-((1-(4-methoxybenzyl)-1H-1,2,3-triazol-4-yl)methyl)acridin-9(10H)-one 8c exhibited the most potency [Formula: see text] against MCF-7 cells, being more potent than etoposide [Formula: see text]. Also, apoptosis induced by compound 8c was confirmed via acridine orange/ethidium bromide and Annexin V-FITC/propidium iodide (PI) double staining.

    Resistance in the sexually transmitted bacterium Mycoplasma genitalium to all recommended therapeutic antimicrobials have rapidly emerged. However, to date, internationally reported resistance surveillance data for M. genitalium strains circulating in Eastern Europe are entirely lacking. The aim of this study was to estimate the prevalence of macrolide and fluoroquinolone resistance-associated mutations in M. genitalium in four cities in Russia and one in Estonia, 2013-2016. Consecutive urogenital samples found positive for M. genitalium during diagnostic testing were retrospectively analyzed for resistance-associated mutations in the 23S rRNA and parC genes using pyrosequencing and conventional Sanger sequencing, respectively. In total, 867 M. genitalium positive samples from 2013-2016 were analyzed. Macrolide resistance-associated mutations were detected in 4.6% of the samples from Russia (0.7-6.8% in different cities) and in 10% of the samples from Estonia. The mutations A2059G and A2058G were highly predominating in both Russia and Estonia, accounting together for 90.9% of the cases positive for nucleotide substitutions in the 23S rRNA gene. The rates of possible fluoroquinolone resistance-associated mutations were 6.2% in Russia (2.5-7.6% in different cities) and 5% in Estonia. The mutations S83I and S83N were the most frequent ones in Russia (24.4% each), whereas D87N highly predominated in Estonia (83.3% of all fluoroquinolone resistance-associated mutations). Approximately 1% of the samples in both countries harbored both macrolide and possible fluoroquinolone resistance-associated mutations, with A2058G and S83I being the most frequent combination (37.5%). The prevalence of macrolide and fluoroquinolone resistance-associated mutations in M. genitalium was 4.6% and 6.2%, respectively, in Russia, and 10% and 5%, respectively, in Estonia. Despite the relatively low rates of macrolide and fluoroquinolone resistance in these countries, antimicrobial resistance

  11. 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)

    Jacopo Lucchetti

    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

    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 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.

    The photo-induced effects in 9,10-phenanthrenequinone-doped (PQ-doped) poly(methyl methacrylate) (PMMA) photopolymer were studied by phase-modulated ellipsometry and polarimetry in real time. The PQ-doped PMMA was exposed to an Ar/Kr tunable laser at the wavelength of 488 nm and measured by a HeNe laser (632.8 nm). We measured the induced birefringence and the variation of the refractive index separately during exposure; there was a difference of three orders of magnitude between these two effects. This suggested that the physical mechanism of holographic recording in PQ-doped PMMA is mainly due to the photo-induced variation in the refractive index.

    9, 10-Phenanthrenequinone (PQ) is regarded as a harmful environmental pollutant and its presence has been reported in atmospheric environment. The measurement of PQ in environment should be necessary to evaluate the influence of PQ on human health. We found that PQ reacted with 2-aminothiophenol under acidic condition to form fluorescent derivative which emits green fluorescence at 510nm. Based on this reaction, a simple and rapid determination method for PQ was developed by HPLC with post-column derivatization and fluorescence detection. By the proposed HPLC system, PQ was detected at 24min and the detection limit was 67fmol/injection (S/N=3). The proposed method was able to determine the atmospheric PQ concentrations by the direct injection of extract from airborne particulates.

    A fairly selective and sensitive spectrophotometric method has been developed for determination of copper after extraction of its 9, 10-phenanthrenequinone monoximate complex into molten naphthalene in the pH range of 6.1-8.4. At room temperature, the solid naphthalene containing the metal complex is separated by filtration, dissolved in dimethylformamide (DMF) and the absorbance measured at 470 nm against the reagent blank. Beer's law is obeyed in the concentration range, 0.0-9.6 micrograms of copper in 10ml of DMF.

    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 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).

    Organic light-emitting devices with tris-(8-hydroxyquinoline) aluminium (Alq 3 ) doped 9,10-di(2-naphthyl) anthracene (ADN) as the emission layer (EML) have been fabricated. These devices exhibit efficient electroluminescence (EL) originated from the Alq 3 as the mass ratio of Alq 3 to ADN was varied from 1 to 50%. The devices with an optimal Alq 3 mass ratio of 10 wt% showed a peak EL efficiency and an external quantum efficiency of 9.1 cd A -1 and 2.7% at a luminance of 1371 cd m -2 , which is improved by a factor of 2.2 compared with 4.1 cd A -1 and 1.2% at a luminance of 3267 cd m -2 for conventional devices with the neat Alq 3 as the EML.

    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.

  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

    2014-05-01

    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.

    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. A pilot study was carried out to estimate the effectiveness of 20 groundwater purification plants with eight diffe...

    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.

    2016-02-01

    Full Text Available Estonia is famous among politicians for its e-Governance policies. One core ingredient for this progress is the abolishment of outdated technologies and standards as this kind of legacy policy slows down the innovation process. This short paper adapts the Estonian approach towards legacy policy and proposes a political symbol initiated by the EU Presidency Trio of the United Kingdom, Bulgaria and Estonia. The entire topic was inspired by the motivation of the Estonian government to use the presidency to make a mark for Estonia. The twice-yearly occurring process of introducing and disabling the summertime, is not only annoying but has also almost exclusively negative impacts. Meanwhile, the summertime itself comes with many aspects of questionable impact and even opposing empirical results, but it also has some generally agreed upon positive influences. This paper takes side against the process of changing times, but does not take position for one of the possible solutions. This short article shall only inform and show the possibilities in regard to the summer time, the EU presidency and the political symbolism of celebrating the centenary of the First World War.

    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.

    Despite the extermination of stray animals and the compulsory vaccination of companion animals, rabies has been widely distributed over Estonia for more than 30 years. The red fox and the raccoon dog are the rabies virus reservoirs. Through a PHARE project, successive oral vaccination campaigns, using Rabidog SAG2 baits, were implemented in the autumn of 2005 in North Estonia, and in the spring and autumn 2006 throughout the whole territory. After the autumn 2005 campaign, 73.5% of the raccoon dogs and foxes were positive for the tetracycline biomarker. After the campaigns of 2006, the seroconversion rate for rabies virus was 64% in both species. After the vaccination campaigns of 2005 and 2006, the incidence of rabies cases dramatically decreased. Of the 97 cases diagnosed in the whole of Estonia until the end of May 2006, 16 cases (16.5%) occurred within the vaccinated area. Only 17 cases were diagnosed between 1 June and 31 December 2006. In 2007, by the end of May, only two rabies cases have been registered.

    2012-04-01

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

    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

    New fluorophore lanthanide complexes-Cloisite (LCs-C) nanohybrids have been prepared by the intercalation reaction of Cloisite Na+ with the tricationic lanthanide complexes (1-3), [M(PQ)3(DMF)2(H2O)2]3+ (M = Pr(III) (1), Gd(III) (2), and Dy(III) (3); PQ = 9,10-phenanthrenequinone), in aqueous solutions. The X-ray diffraction analysis of the modified clays (LCs-C) showed an increase in the interlayer distance (d) as compared to the pure Cloisite Na+. Field-emission scanning electron microscopy (FE-SEM) was used to study the morphology of the modified clays and the results were demonstrated a homogeneous morphology for the nanohybrids. The thermal behavior of the LCs-C nanohybrids was investigated using thermogravimetric analysis. Solid-state fluorescence properties of the LCs-C nanohybrids were also investigated. The results show that all tricationic complexes have a significant fluorescence at room temperature when the complexes are adsorbed onto Cloisite.

    2016-09-02

    9,10-Phenanthrenequinone (PQ) was successfully used as a new mass-tagging reagent for sensitive labeling of aliphatic aldehydes (C3-C10) prior liquid chromatography-electrospray ionization-tandem mass spectrometry (LC/ESI-MS/MS). This reagent could overcome the drawbacks of previous amine or hydrazine-based reagents, such as lower sensitivity, formation of two stereoisomeric reaction products for each single analyte, need for longer derivatization time, and poor reactivity with aliphatic aldehydes. The PQ-aldehyde derivatives exhibited intense [M+H](+) and a common product ion with ESI in the positive-ion mode. The derivatives were monitored at the transition of [M+H](+)→m/z 231.9 with detection limits from 4.0 to 100 pM (signal to noise ratio=3). 3-Phenylpropanal was used as an internal standard (IS) and the separation of the eight aldehydes and IS was achieved in less than 10min employing gradient elution with methanol and ammonium formate buffer (20mM, pH 4.0). The method employed salting out liquid-liquid extraction for aliphatic aldehydes form serum for the first time with excellent recoveries (92.6-110.8%). The developed method was validated and applied for quantification of the target aldehydes in serum of healthy volunteers (n=14). Copyright © 2016 Elsevier B.V. All rights reserved.

    New fluorophore lanthanide complexes-Cloisite (LCs-C) nanohybrids have been prepared by the intercalation reaction of Cloisite Na(+) with the tricationic lanthanide complexes (1-3), [M(PQ)3(DMF)2(H2O)2](3+) (M=Pr(III) (1), Gd(III) (2), and Dy(III) (3); PQ=9,10-phenanthrenequinone), in aqueous solutions. The X-ray diffraction analysis of the modified clays (LCs-C) showed an increase in the interlayer distance (d) as compared to the pure Cloisite Na(+). Field-emission scanning electron microscopy (FE-SEM) was used to study the morphology of the modified clays and the results were demonstrated a homogeneous morphology for the nanohybrids. The thermal behavior of the LCs-C nanohybrids was investigated using thermogravimetric analysis. Solid-state fluorescence properties of the LCs-C nanohybrids were also investigated. The results show that all tricationic complexes have a significant fluorescence at room temperature when the complexes are adsorbed onto Cloisite. Copyright © 2014 Elsevier B.V. All rights reserved.

    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.

    Penning trap mass measurements of 9 Be, 10 Be (t 1/2 =1.51 My), and the one-neutron halo nuclide 11 Be (t 1/2 =13.8 s) have been performed using TITAN at TRIUMF. The resulting 11 Be mass excess (ME=20177.60(58) keV) is in agreement with the current Atomic Mass Evaluation (AME03) [G. Audi, et al., Nucl. Phys. A 729 (2003) 337] value, but is over an order of magnitude more precise. The precision of the mass values of 9,10 Be have been improved by about a factor of four and reveal a ∼2σ deviation from the AME mass values. Results of new atomic physics calculations are presented for the isotope shift of 11 Be relative to 9 Be, and it is shown that the new mass values essentially remove atomic mass uncertainties as a contributing factor in determining the relative nuclear charge radius from the isotope shift. The new mass values of 10,11 Be also allow for a more precise determination of the single-neutron binding energy of the halo neutron in 11 Be.

    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 monolayer behavior of bis[2,3,9,10,16,17,24,25-octakis(octyloxy)phthalocyaninato] rare earth complexes M[Pc(OC 8 H 17 ) 8 ] 2 (M = Eu, Dy, Er) at the air-water interface and their ordered molecular assemblies fabricated by Langmuir-Blodgett technique have been investigated by a series of techniques including surface pressure-area isotherms, electronic absorption spectra, polarized absorption spectra, low-angle X-ray diffraction patterns, and transmission electron microscope (TEM). The results indicated that bis(phthalocyaninato) rare earth molecules form well-ordered stable monolayers with a face-to-face configuration and edge-on arrangement to the water surface at the air-water interface and lamellar multilayers on solid substrates. The orientation angle of phthalocyanine rings with respect to the quartz plate surface in the Langmuir-Blodgett films has been determined to be 64.6 o , 63.5 o , and 63.3 o for the Eu, Dy, and Er double-decker complexes, respectively, by the polarized absorption spectroscopy. High-resolution TEM reveals that a series of well-ordered rodlike aggregates of bis(phthalocyaninato) rare earth complexes, which can be considered as molecular cable arrays, were formed by self-organization in the monolayers

    Prominent published and active human papillomavirus (HPV) modelers from around the world were invited to participate in the inaugural Modeling Evidence in HPV (MEHPV) Pre-Conference Workshop on May 9-10, 2009, in Malmö, Sweden. The workshop took place directly before the 25th International Papillomavirus Conference. 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.

  7. First steps in photophysics. I. Fluorescence yield and radiative rate coefficient of 9,10-bis(phenylethynyl)anthracene in paraffins.

    The fluorescence quantum yield of 9,10-bis(phenylethynyl)anthracene (BPEA) is almost unity in every examined solvent. Using different hydrocarbons, one can make a convenient and sufficiently accurate experimental test for determination of the extent of the refractive index correction needed in fluorescence quantum yield determination on a given fluorometer. By comparison of the measurements in n-pentane-cis-decaline or n-hexane-toluene solvent pairs, the requirement of the n(2) correction is confirmed for most of the fluorometers; however, for one of the examined pieces of equipment the necessary correction proved to be slightly lower. By excited state's lifetime measurements, the refractive index dependence of the fluorescence rate coefficient was reexamined. At 25 °C for BPEA the relationship is in agreement with Bakhshiev's prediction: the experimentally determined exponent of n in the rate coefficient deriving equation is around 1.32 using different paraffins as solvents. The negative temperature coefficient of the radiative rate in part originates from the temperature dependence of the refractive index, while also a small intrinsic contribution has been found.

  8. Determination of the individual atomic site contribution to the electronic structure of 3,4,9,10-perylene-tetracarboxylic-dianhydride (PTCDA)

    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

    Five 9,10-bis((4-N,N-dialkylamino)styryl) anthracene derivatives (DSA-C1-DSA-C7) with different length alkyl chains were synthesized. They showed the same color in dilute solutions but different colors in crystals. The absorption, photoluminescence, and fluorescence decay indicate that there exist both excitonic and dipolar coupling in crystals of DSA-C1-DSA-C7. X-ray crystallographic analysis revealed that all the crystals belong to the triclinic space group P1 with one molecule per unit cell and that the molecules in every crystal have the identical orientation. This offers ideal samples to investigate the impact of the molecular stacking on the optical properties of the crystals. For the first time, the cooperation of excitonic and dipolar coupling has been comprehensively studied, and the contribution to the spectral shift from the excitonic and dipolar couplings quantitatively obtained. The experiments of amplified spontaneous emission (ASE) together with measurements of the quantum efficiency further confirmed this interpretation. The results suggest that the excitonic and dipolar couplings between the adjacent molecules are both important and jointly induce the spectral shifts of the crystals. © 2014 WILEY-VCH Verlag GmbH & Co.

    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.

    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.

    This study examined the relationship between multiple dimensions of religious involvement and transitions of tobacco smoking abstinence, persistence, cessation and relapse over 9-10 years of follow-up in a national sample of adults in the United States. Using data provided at baseline and follow-up, participants were categorized as non-smokers, persistent smokers, ex-smokers, and relapsed smokers. Religious involvement over the two time points were categorized into combinations of "high" and "low" involvement within the domains of (a) religious attendance, (b) religious importance, (c) spiritual importance, (d) religious/spiritual comfort seeking, and (e) religious/spiritual decision-making. High levels of religious involvement across five dimensions (religious attendance, religious importance, spiritual importance, religious/spiritual comfort-seeking, and religious/spiritual decision-making) were associated with lower odds of being a persistent smoker or ex-smoker. Religious involvement was not associated with smoking cessation among smokers at baseline. Interventions to increase smoking abstinence may be more effective if they draw on ties to religious and spiritual organizations and beliefs. Meanwhile, religious involvement is unlikely to affect smoking cessation effectiveness. Copyright © 2015 Elsevier Ltd. All rights reserved.

    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 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.

    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 overall purpose of this report on energy-saving measures is to provide the Estonian Ministry of Economics and Communication with an overview of the energy consumption on poultry farms at a national level. This report compromises detailed information on energy consumption per ton of broiler meat, egg and young laying hen produced in Estonia and Denmark, respectively, based on field investigations and Danish statistics. To collect information on electricity consumption within Estonian poultry farming on a national level, three pilot farms were analysed with regard to the use of energy consumption on each farm. Results from the three farms are presented in Appendix 1. In addition, a calculation of national energy consumption within chicken meet production, egg production and breeding of young laying hens is presented in this report. The calculation shows the difference between the Danish and Estonian energy consumption on poultry farms. This report presents a proposal for a ten-year development plan for the reduction of the energy consumption on Estonian poultry farms. (au)

    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.

    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.

  20. Quaternary deposits and weathered bedrock material as a source of dangerous radon emissions in Estonia

    2015-06-01

    Full Text Available The risk of dangerous radon emissions in Estonia is high, being among the highest in Europe. In almost 33 per cent of Estonian land area, the content of radon in soil-contained air exceeds the safe limit for unrestricted construction (50 kBq/m3. In such high radon-risk areas the concentration of radon in soil-contained air ranges from 50 to 400 kBq/m3, in a few cases reaching up to 2,100 kBq/m3 exceeding the permitted level for residential areas. The situation is particularly serious in the northernmost part of the country, where uranium-rich graptolite argillite (Dictyonema shale and the Obolus phosphorite are close to ground surface and their particles are constituent parts of Quaternary deposits. Radon emissions from bedrock have been investigated in detail, but to date Quaternary strata as a source of radon emissions are poorly studied. According to our measurements the highest concentrations of radon are related to tills containing clasts and fines of graptolite argillite and phosphorite. Glacial deposits include also granitoidal material, containing U, Th and K, which have been transported by glaciers from the outcrop areas of crystalline basement rocks in Finland and the Gulf of Finland. Due to weathering, outwash and repeated redeposition other genetic types are poorer in radioactive elements and they are weaker sources of radon.
