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

Directory of Open Access Journals (Sweden)

Hent-Raul Kalmo

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

On the System of Place Name Signs in Estonian Sign Language

Directory of Open Access Journals (Sweden)

Liina Paales

2011-05-01

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

Emission from Estonian oil shale power plants

1995-01-01

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

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

Directory of Open Access Journals (Sweden)

Mägi, Vahur

2013-03-01

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

Full Text Available The paper analyses Estonian tax structure changes during the last decade and critically assesses the current situation. The country’s tax mix is rather unique among EU countries – it has one of the highest proportions of consumption taxes in total taxes and the lowest level of capital and profit taxes. Such an unbalanced tax structure creates risks for public finances, limits revenue collection and distorts the business environment.

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

Directory of Open Access Journals (Sweden)

Katri Aaslav-Tepandi

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

Liberalism - Key to Entrepreneurial and Innovation Success: Estonian Case Study

Augustin Ignatov

2017-12-01

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

Efficiency of Estonian grain farms in 2000 2004

2008-12-01

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

The Category of Time in Fairy Tales: Searching for Folk Calendar Time in the Estonian Fairy Tale Corpus

Directory of Open Access Journals (Sweden)

Mairi Kaasik

2011-03-01

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

Revisiting the Estonian Cyber Attacks: Digital Threats and Multinational Responses

Directory of Open Access Journals (Sweden)

Stephen Herzog

2011-01-01

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

The Woman as Wolf (AT 409: Some Interpretations of a Very Estonian Folk Tale

Directory of Open Access Journals (Sweden)

Merili Metsvahi

2013-12-01

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

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

Russian-Estonian Economic and Investment Cooperation During the Crisis: Dynamics and Possibilities

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

Overview of the Estonian Biofuels Association activities

Hueues, Meelis

2000-01-01

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

2017-09-01

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

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

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

2002-01-01

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

Tabud ja reeglid. Sissevaateid eesti laagriromaani / Taboos and Rules. Insights into Prison Camp Novels by Estonian Writers

Directory of Open Access Journals (Sweden)

Anneli Kõvamees

2013-12-01

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

In may five energy forest plantations (altogether 2 ha) were established in Estonia with Swedish selected clones of Salix viminalis and Salix dasyclados. The research within this project is carried out within three main directions. The studies of basic ecophysiological processes and radiation regime of willow canopy will be carried out in Toravere. The production ecology studies, comparison of the productivity of multiple clones on different soil types is based on the plantations as vegetation filter for wastewater purification is studied on the basis of plantations in Vaeike-Maarja and Valga (author)

Estonian wind climate

International Nuclear Information System (INIS)

Kull, Ain

1999-01-01

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

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

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

Utilisation of Estonian energy wood resources

1996-12-31

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

Pärna, K; Rahu, K; Rahu, M

2005-05-01

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

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

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

Chemistry of the Estonian oil-shale kukersite

Energy Technology Data Exchange (ETDEWEB)

Kogerman, P N

1931-01-01

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

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

Directory of Open Access Journals (Sweden)

Katrin Kello

2018-02-01

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

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

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

Sak, Katrin; Jürisoo, Kadi; Raal, Ain

2014-07-01

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

HIV testing and counselling in Estonian prisons, 2012 to 2013: aims, processes and impacts.

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

In this model, A- and B-species aggregates perform self-exchange-driven growths with the exchange rate kernels K (k,l) = Kkl and L(k,l) = Lkl, respectively, and the two species aggregates perform self-birth processes with the rate kernels J 1 (k) = J 1 k and J 2 (k) = J 2 k, and meanwhile the interaction between the aggregates of different species A and B causes a lose-lose scheme with the rate kernel H(k,l) = Hkl. Based on the mean-field theory, we investigated the evolution behaviors of the two species aggregates to study the competitions among above three aggregate evolution schemes on the distinct initial monomer concentrations A 0 and B 0 of the two species. The results show that the evolution behaviors of A- and B-species are crucially dominated by the competition between the two self-birth processes, and the initial monomer concentrations A 0 and B 0 play important roles, while the lose-lose scheme play important roles in some special cases.

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

2012-04-01

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

Acquisition of noun derivation in Estonian and Russian L1

Directory of Open Access Journals (Sweden)

Reili Argus

2018-04-01

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

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

Directory of Open Access Journals (Sweden)

Pomozi, Péter

2016-12-01

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

Field of genes: the politics of science and identity in the Estonian Genome Project.

Science.gov (United States)

Fletcher, Amy L

2004-04-01

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

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

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

Directory of Open Access Journals (Sweden)

Kanni Labi

2012-04-01

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

Mutational analysis of COL1A1 and COL1A2 genes among Estonian osteogenesis imperfecta patients.

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

Radon in Estonian buildings. Establishment of a measurement system and obtained results

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

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

Directory of Open Access Journals (Sweden)

Maarja Siiner

2017-05-01

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

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

Directory of Open Access Journals (Sweden)

Janek Kraavi

2012-04-01

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

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

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

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

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

Directory of Open Access Journals (Sweden)

Liisi Sepp

2013-01-01

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

The dominance of indirect taxes in Estonian state budget. Summary:Kaudsete maksude dominant Eesti riigieelarve tuludes

2013-09-01

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

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

Organic farming and demand for organic products is continually a growing trend all over the world (Willer et al., 2013). In Estonia the share of organic land is 15% of all agricultural land and the number of organic farmers is also growing (Vetemaa, Mikk 2013). Estonian organic food market is still in forming stage being affected by local organic farming development, marketing situation, economic situation and consumer attitudes.

The Dominance of Indirect Taxes in Estonian State Budget

Directory of Open Access Journals (Sweden)

Olev Raju

2013-01-01

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

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

Where Do Dead Books Go? The Problem of the Soviet Canon Today, on the Example of Johannes Becher's Work in Estonian

2013-06-01

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

With or without articles? A comparison of article-like determiners in Estonian and Finnish

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

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

INTERDISCIPLINARY PHYSICS AND RELATED AREAS OF SCIENCE AND TECHNOLOGY: Aggregation Behaviors of a Two-Species System with Lose-Lose Interactions

Song, Mei-Xia; Lin, Zhen-Quan; Li, Xiao-Dong; Ke, Jian-Hong

2010-06-01

We propose an aggregation evolution model of two-species (A- and B-species) aggregates to study the prevalent aggregation phenomena in social and economic systems. In this model, A- and B-species aggregates perform self-exchange-driven growths with the exchange rate kernels K (k,l) = Kkl and L(k,l) = Lkl, respectively, and the two species aggregates perform self-birth processes with the rate kernels J1(k) = J1k and J2(k) = J2k, and meanwhile the interaction between the aggregates of different species A and B causes a lose-lose scheme with the rate kernel H(k,l) = Hkl. Based on the mean-field theory, we investigated the evolution behaviors of the two species aggregates to study the competitions among above three aggregate evolution schemes on the distinct initial monomer concentrations A0 and B0 of the two species. The results show that the evolution behaviors of A- and B-species are crucially dominated by the competition between the two self-birth processes, and the initial monomer concentrations A0 and B0 play important roles, while the lose-lose scheme play important roles in some special cases.

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

Ärkamisaeg, Noor-Eesti ja miski nende vahel. Eesti kirjandusloo küsimusi Juhan Kunderi näitel / National Awakening , Young Estonia and Something In Between. Problems of Estonian Literary History in the Example of Juhan Kunder

2013-12-01

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

Fighting for and losing or gaining control in life.

Science.gov (United States)

Theorell, T

1997-01-01

In JP Henry's work, fighting for and losing control were important concepts in the interpretation of energy mobilization in psychosocial conditions. Attachment and support were important protective and salutogenic factors. These concepts have been applied in a series of epidemiological and psychophysiological real life studies. Job conditions which force the worker to mobilize energy and concomitantly inhibit anabolism could be identified at least partly by means of the demand-control-support model originally proposed by Karasek. The most adverse conditions at work arise when psychological demands are high and at the same time the decision latitude is low. This combination is associated with changes in the regulation of endocrine parameters as well as with increased morbidity--heart disease, functional gastrointestinal symptoms and musculoskeletal disorders. Examples of studies of physiological correlates of psychosocial processes leading to fight for control are also described from outside work activities.

2017-07-01

The ketogenic diet is an effective treatment for the patients with intractable epilepsy, however, the diet therapy can sometimes be discontinued by complications. Protein-losing enteropathy is a rarely reported serious complication of the ketogenic diet. We present a 16-month-old Down syndrome baby with protein-losing enteropathy during the ketogenic diet as a treatment for West syndrome. He suffered from diarrhea, general edema and hypoalbuminemia which were not controlled by conservative care for over 1 month. Esophagogastroduodenoscopy and stool alpha-1 antitrypsin indicated protein-losing enteropathy. Related symptoms were relieved after cessation of the ketogenic diet. Unexplained hypoalbuminemia combined with edema and diarrhea during ketogenic suggests the possibility of protein-losing enteropathy, and proper evaluation is recommended in order to expeditiously detect it and to act accordingly. © Copyright: Yonsei University College of Medicine 2017.

2012-04-01

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

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

Directory of Open Access Journals (Sweden)

Anneli Mihkelev

2013-06-01

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

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

2015-04-01

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

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

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

MODELLING DICLOFENAC AND IBUPROFEN RESIDUES IN MAJOR ESTONIAN SEASIDE CITIES

2016-06-01

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

Thermoregulatory model of sleep control: losing the heat memory.

Science.gov (United States)

Nakao, M; McGinty, D; Szymusiak, R; Yamamoto, M

1999-12-01

Thermoregulatory mechanisms were hypothesized to provide primary control of non-rapid-eye-movement sleep (NREM). On the basis of this hypothesis, we incorporated the thermoregulatory feedback loops mediated by the "heat memory," heat load, and loss processes associated with sleep-wake cycles, which were modulated by two circadian oscillators. In addition, hypnogenic warm-sensitive neurons (HWSNs) were assumed to integrate thermoregulation and NREM control. The heat memory described above could be mediated by some sleep-promoting substances. In this paper, considering the possible carrier of the heat memory, its losing process is newly included in the model. The newly developed model can generate the appropriate features of human sleep-wake patterns. One of the special features of the model is to generate the bimodal distribution of the sleepiness. This bimodality becomes distinct, as the losing rate of the heat memory decreases or the amplitude of the Y oscillator increases. The theoretical analysis shows the losing rate of the heat memory control's rapidity of model response to a thermal perturbation, which is confirmed by simulating the responses with various losing rates to transient heat loads ("heat load pulse"). The sleepiness exhibits large responses to the heat load pulses applied in the early and late phases of wake period, while the response is significantly reduced to the pulse applied in the supposed wake-maintenance zone. This bimodality of the response appears to reflect the sensitivity of the HWSNs. In addition, the early pulse raises the immediate sleepiness rather than the nocturnal sleepiness, while the heat load pulse applied in the later phase of waking period significantly raises the sleepiness during a nocturnal sleep. In simulations of sleep deprivation, the discontinuous relationship between recovery sleep length and deprivation time is reproduced, where the critical sleep deprivation time at which the recovery sleep length jumps is extended

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

Losing Items in the Psychogeriatric Nursing Home

J. van Hoof PhD

2016-09-01

Full Text Available Introduction: Losing items is a time-consuming occurrence in nursing homes that is ill described. An explorative study was conducted to investigate which items got lost by nursing home residents, and how this affects the residents and family caregivers. Method: Semi-structured interviews and card sorting tasks were conducted with 12 residents with early-stage dementia and 12 family caregivers. Thematic analysis was applied to the outcomes of the sessions. Results: The participants stated that numerous personal items and assistive devices get lost in the nursing home environment, which had various emotional, practical, and financial implications. Significant amounts of time are spent on trying to find items, varying from 1 hr up to a couple of weeks. Numerous potential solutions were identified by the interviewees. Discussion: Losing items often goes together with limitations to the participation of residents. Many family caregivers are reluctant to replace lost items, as these items may get lost again.

Living with clipped wings—Patients’ experience of losing a leg

Directory of Open Access Journals (Sweden)

Annelise Norlyk

2013-10-01

Full Text Available This study explores the lived experience of losing a leg as described by the patients themselves post-discharge. Studies have documented that regardless of aetiology patients are faced with severe physical as well as psychosocial challenges post-amputation. However, only few studies explore in-depth the patients’ perspective on the various challenges following the loss of a leg. The study uses the phenomenological approach of Reflective Lifeworld Research (RLR. Data were collected from 24 in-depth interviews with 12 Danish patients. Data analysis was performed according to the guidelines given in RLR. The essential meaning of losing a leg is a radical and existential upheaval, which restricts patients’ lifestyle and irretrievably alters their lifeworld. Life after the operation is associated with despair, and a painful sense of loss, but also with the hope of regaining personal independence. The consequences of losing a leg gradually materialize as the patients realize how the loss of mobility limits their freedom. Patients experience the professional help as primarily directed towards physical care and rehabilitation. The findings show that the loss of a leg and, subsequently, the restricted mobility carry with them an existential dimension which refers to limitation of action space and loss of freedom experienced as an exclusion from life. Our findings demonstrate a need for complementary care and stress the importance of an increased awareness of the psychosocial and existential consequences of losing a limb.

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

Science.gov (United States)

Sõukand, Renata; Kalle, Raivo

2011-05-17

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

2012-01-01

Full Text Available Abstract Introduction Systemic lupus erythematosus is a disease which may initially present with varying symptoms, most commonly a photosensitive rash and arthritis. Protein losing enteropathy is a recognized but rare presenting manifestation. Diagnosing protein losing enteropathy in resource limited centres is challenging but possible through the exclusion of other possible causes of hypoalbunaemia. Case Presentation We report a case of protein losing gastroenteropathy secondary to intestinal lymphangiectasia as the initial manifestation of systemic lupus erythematosus in a 57 year old Sri Lankan (South Asian male patient. The diagnosis was made by the exclusion of other causes of hypoalbuminaemia as the gold standard investigations for protein losing enteropathy were not available at this centre. Conclusions Protein losing enteropathy is a diagnosis of exclusion in resource limited centres in the world. Systemic lupus erythematosus should be considered in the differential diagnosis of protein losing enteropathy. Intestinal lymphangiectasia should also be recognized as a possible pathophysiological mechanism.

The ambivalence of losing weight after bariatric surgery

Directory of Open Access Journals (Sweden)

Christine Warholm

2014-01-01

Full Text Available This study is grounded in a phenomenological lifeworld perspective. It aims at providing rich descriptions of lived experience of the process of losing weight after obesity surgery. Two women participated in in-depth interviews four times each during the first postoperative year. Based on the women's experiences, a meaning structure—the ambivalence of losing weight after obesity surgery—was identified across the women's processes of change. This consisted of five core themes: movement and activity—freedom but new demands and old restraints; eating habits and digestion—the complexity of change; appearance—smaller, but looser; social relations—stability and change; and being oneself—vulnerability and self-assurance. These core themes changed over time in terms of dominance. The experience of ambivalence is discussed according to a phenomenological perspective of the body as lived experience.

Why radiologists lose their hospital contracts: is your contract secure?

Science.gov (United States)

Muroff, Lawrence R

2010-03-01

Previously, a hospital contract meant tenure for the incumbent group of radiologists; however, those days are long gone. Exclusive contracts have morphed into exclusive contracts with carve-outs. Turf erosion has become a fact of life for radiology practices. Now radiologists are losing their hospital contracts in record numbers. Group size, though helpful for a variety of reasons, does not ensure that a practice will be secure in its hospital setting. The reasons that groups lose their hospital contracts are varied, and in this paper, the author discusses the most common ones. Suggestions to help practices avoid this unfortunate fate are presented.

Chernobyl is still haunting us. Radionuclides in Estonian mushrooms

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

1993-01-01

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

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

Directory of Open Access Journals (Sweden)

Ene-Reet Soovik

2012-06-01

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

Protein-losing enteropathy is a primary or secondary manifestation of a group of conditions, and etiologies which are broadly divisible into those with mucosal injury on the basis of inflammatory and ulcerative conditions, mucosal injury without erosions or ulcerations, and lymphatic abnormalities. We describe the first case of protein-losing enteropathy in a pediatric patient, with severe skeletal dysplasia consistent with thanatophoric dysplasia type I and DNA analysis that revealed a c.1949A>T (p.Lys650Met) in exon 15 of the FGFR3 gene. She presented with protein-losing enteropathy in her 6th month. Post-mortem examination revealed lymphangiectasia in the small intestine. To our knowledge, this is the first report of intestinal lymphangiectasia as a complication of skeletal dysplasia resulting in severe protein-losing enteropathy. © 2016 Wiley Periodicals, Inc. © 2016 Wiley Periodicals, Inc.

2014-05-28

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

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

Science.gov (United States)

Lõo, Kaidi; Järvikivi, Juhani; Baayen, R Harald

2018-06-01

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

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

History of experimental psychology from an Estonian perspective.

Science.gov (United States)

Allik, Jüri

2007-11-01

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

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

Rita Anita Forssten

2017-05-01

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

Attempts to lose weight among overweight and non-overweight adolescents: a cross-national survey

2007-10-01

Full Text Available Abstract Background Despite the global obesity epidemic, few studies have performed cross-national comparisons of adolescents' attempts to lose weight and weight control practices. This study aims to investigate matters mentioned above by weight status in Europe, Israel, and North America. Methods Nationally representative samples of adolescents from over 30 countries completed an anonymous, standardized questionnaire as part of the Health Behaviour in School-aged Children 2001/2002 survey. The prevalence and likelihood of attempts to lose weight were determined. The effect of weight status, self-perception of overweight, age and country of residence upon the likelihood of current attempts to lose weight were evaluated using multilevel multivariate logistic regression in separate analyses for boys and girls. The study also presented the prevalence of weight control practices of overweight and non-overweight adolescents who had controlled their weight in seven countries. Results In general, overweight and obese adolescents were more likely to be engaged in current attempts to lose weight and had tried to control their weight during the past 12 months more often than non-overweight adolescents. Besides weight status, self-perception of overweight and age were significant individual-level factors determining current attempts to lose weight. Country of residence was a significant second-level factor but no clear geographical pattern was found. Several gender-related differences existed. Conclusion The findings indicated that most overweight adolescents were motivated to reduce their weight. The importance of promoting a healthy body image for all adolescents was highlighted by the fact that self-perception of overweight was found to be the most important factor leading to attempts to lose weight.

Predictors of trying to lose weight among overweight and obese Mexican-Americans: a signal detection analysis.

Bersamin, Andrea; Hanni, Krista D; Winkleby, Marilyn A

2009-01-01

Signal detection analysis, a form of recursive partitioning, was used to identify combinations of sociodemographic and acculturation factors that predict trying to lose weight in a community-based sample of 957 overweight and obese Mexican-American adults (ages 18-69 years). Data were pooled from the 2004 and 2006 Behavioral Risk Factor Surveillance System conducted in a low-income, semi-rural community in California. Overall, 59 % of the population reported trying to lose weight. The proportion of adults who were trying to lose weight was highly variable across the seven mutually exclusive groups identified by signal detection (range 30-79 %). Significant predictors of trying to lose weight included BMI, gender, age and income. Women who were very overweight (BMI > 28.5 kg/m2) were most likely to be trying to lose weight (79 %), followed by very overweight higher-income men and moderately overweight (BMI = 25.0-28.5 kg/m2) higher-income women (72 % and 70 %, respectively). Moderately overweight men, aged 28-69 years, were the least likely to be trying to lose weight (30 %), followed by moderately overweight lower-income women (47 %) and very overweight lower-income men (49 %). The latter group is of particular concern since they have characteristics associated with medical complications of obesity (low education and poor access to medical care). Our findings highlight opportunities and challenges for public health professionals working with overweight Mexican-American adults - particularly lower-income adults who were born in Mexico - who are not trying to lose weight and are therefore at high risk for obesity-related co-morbidities.

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

Full Text Available The objective of the present study was to analyze the differences in rugby game statistics between winning and losing teams. The data from 58 games of round robin play from the Six Nations tournament from the 2003-2006 seasons were analyzed. The groups of variables studied were: number of points scored, way in which the points were scored; way teams obtained the ball and how the team used it; and technical and tactical aspects of the game. A univariate (t-test and multivariate (discriminant analysis of data was done. Winning teams had average values that were significantly higher in points scored, conversions, successful drops, mauls won, line breaks, possessions kicked, tackles completed, and turnovers won. Losing teams had significantly higher averages for the variables scrums lost and line-outs lost. The results showed that: a in the phases of obtaining the ball and more specifically in scrummage and line-out, winning teams lose fewer balls than losing teams (winning teams have an efficacy of 90% in both actions; b the winning team tends to play more with their feet when they obtain the ball, to utilize the maul as a way of attacking, and to break the defensive line more often than the losing team does; and c On defence, winning teams recovered more balls and completed more tackles than losing teams, and the percentage of tackles completed by winning teams was 94%. The value presented could be used as a reference for practice and competition in peak performance teams

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

2012-04-01

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

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

International Nuclear Information System (INIS)

Meinander, O.

1995-01-01

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

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

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

Losing ground--Swedish life expectancy in a comparative perspective.

Directory of Open Access Journals (Sweden)

Sven Drefahl

Full Text Available BACKGROUND: In the beginning of the 1970s, Sweden was the country where both women and men enjoyed the world's longest life expectancy. While life expectancy continues to be high and increasing, Sweden has been losing ground in relation to other leading countries. METHODS: We look at life expectancy over the years 1970-2008 for men and women. To assess the relative contributions of age, causes of death, and smoking we decompose differences in life expectancy between Sweden and two leading countries, Japan and France. This study is the first to use this decomposition method to observe how smoking related deaths contribute to life expectancy differences between countries. RESULTS: Sweden has maintained very low mortality at young and working ages for both men and women compared to France and Japan. However, mortality at ages above 65 has become considerably higher in Sweden than in the other leading countries because the decrease has been faster in those countries. Different trends for circulatory diseases were the largest contributor to this development in both sexes but for women also cancer played a role. Mortality from neoplasms has been considerably low for Swedish men. Smoking attributable mortality plays a modest role for women, whereas it is substantially lower in Swedish men than in French and Japanese men. CONCLUSIONS: Sweden is losing ground in relation to other leading countries with respect to life expectancy because mortality at high ages improves more slowly than in the leading countries, especially due to trends in cardiovascular disease mortality. Trends in smoking rates may provide a partial explanation for the trends in women; however, it is not possible to isolate one single explanatory factor for why Sweden is losing ground.

Living, loving and losing: implications for health and well-being.

Downey, A M

1983-01-01

Living, loving and losing - we live, we love and we lose - this is an integral part of life's unending circle. Throughout the lifecycle, we are confronted continually with experiences of loss and separation. The loss of a loved one through separation, divorce, or death is one of the most difficult experiences to be dealt with in a lifetime. How do we cope with the "crisis of loss" in our lives? If education is supposed to prepare one for life, then Death Education is crucial in assisting individuals to cope with "myriad loss issues." This paper will explore the implications of loss for health and well-being, and briefly review some of the research findings regarding the negative impact of grief and bereavement upon health. The stages of the grief process will be cited, mentioning some of the barriers to grief resolution. Most importantly, the positive aspects of loss upon life and health will be elaborated.

Anorexia: A "losing" strategy?

Science.gov (United States)

Mealey, L

2000-03-01

Several theorists have tried to model anorexia on Wasser and Barash's (1983) "reproductive suppression model" (RSM). According to the RSM, individual females adaptively suppress their reproductive functioning under conditions of social or physiological stress. From this perspective, mild anorexia is viewed as an adaptive response to modern conditions; more severe anorexia is viewed as an adaptation gone awry. Previous models have not, however, examined the full richness of the RSM. Specifically, Wasser and Barash documented not only self-imposed reproductive suppression, but also manipulative reproductive suppression of subordinate females by dominants. I propose that the modern "epidemic" of anorexia is explained neither by adaptive self-suppression nor by environmental mismatch (an adaptation gone awry); I propose that the "epidemic" levels of anorexia seen in modern western society are a direct consequence of intrasexual competition, the scope of which has been enhanced by the power and reach of modern communications media. According to this perspective, anorexia, even in its mild forms, is a manipulative strategy imposed on subordinates by dominants. Anorexia is, in both senses, a "losing" strategy.

Towards The Operational Oceanographic Model System In Estonian Coastal Sea, Baltic Sea

Kõuts, T.; Elken, J.; Raudsepp, U.

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

Predicting losing and gaining river reaches in lowland New Zealand based on a statistical methodology

The phenomenon of losing and gaining in rivers normally takes place in lowland where often there are various, sometimes conflicting uses for water resources, e.g., agriculture, industry, recreation, and maintenance of ecosystem function. To better support water allocation decisions, it is crucial to understand the location and seasonal dynamics of these losses and gains. We present a statistical methodology to predict losing and gaining river reaches in New Zealand based on 1) information surveys with surface water and groundwater experts from regional government, 2) A collection of river/watershed characteristics, including climate, soil and hydrogeologic information, and 3) the random forests technique. The surveys on losing and gaining reaches were conducted face-to-face at 16 New Zealand regional government authorities, and climate, soil, river geometry, and hydrogeologic data from various sources were collected and compiled to represent river/watershed characteristics. The random forests technique was used to build up the statistical relationship between river reach status (gain and loss) and river/watershed characteristics, and then to predict for river reaches at Strahler order one without prior losing and gaining information. Results show that the model has a classification error of around 10% for "gain" and "loss". The results will assist further research, and water allocation decisions in lowland New Zealand.

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

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

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

Loss aversion is one of the most robust findings to have emerged from behavioral economics. Surprisingly little attention, however, has been devoted to nominal loss aversion, the interaction of loss aversion and money illusion. People tend to think of transactions in terms of their nominal...... (monetary) values. Real losses may therefore loom larger in people’s minds when they lose money than when real losses are hidden by purely nominal gains. Using a survey experiment with a large and heterogeneous sample, we show that evaluations of housing transactions are systematically biased by purely...... nominal gains versus losses....

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

International Nuclear Information System (INIS)

Lund, H.; Hvelplund, F.; Ingermann, K.; Kask, U.

2000-01-01

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

It has also been verified that the aspiration-based win-stay-lose-learn strategy updating rule promotes the evolution of cooperation. Inspired by this well-known fact, we combine the Win-Stay-Lose-Learn updating rule with voluntary participation: Players maintain their strategies when they are satisfied, or players attempt to imitate the strategy of one randomly chosen neighbor. We find that this mechanism maintains persistent cooperative behavior, even further promotes the evolution of cooperation under certain conditions.

Research on the Obstacle Negotiation Strategy for the Heavy-duty Six-legged Robot based on Force Control

Full Text Available To make heavy-duty six-legged robots without environment reconstruction system negotiate obstacles after the earthquake successfully, an obstacle negotiation strategy is described in this paper. The reflection strategy is generated by the information of plantar force sensors and Bezier Curve is used to plan trajectory. As the heavy-duty six-legged robot has a large inertia, force controller is necessary to ensure the robot not to lose stability while negotiating obstacles. Impedance control is applied to reduce the impact of collision and active force control is applied to adjust the pose of the robot. The robot can walk through zones that are filled with obstacles automatically because of force control. Finally, the algorithm is verified in a simulation environment.

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

BFPTool: a software tool for analysis of Biomembrane Force Probe experiments.

The Biomembrane Force Probe is an approachable experimental technique commonly used for single-molecule force spectroscopy and experiments on biological interfaces. The technique operates in the range of forces from 0.1 pN to 1000 pN. Experiments are typically repeated many times, conditions are often not optimal, the captured video can be unstable and lose focus; this makes efficient analysis challenging, while out-of-the-box non-proprietary solutions are not freely available. This dedicated tool was developed to integrate and simplify the image processing and analysis of videomicroscopy recordings from BFP experiments. A novel processing feature, allowing the tracking of the pipette, was incorporated to address a limitation of preceding methods. Emphasis was placed on versatility and comprehensible user interface implemented in a graphical form. An integrated analytical tool was implemented to provide a faster, simpler and more convenient way to process and analyse BFP experiments.

Losing the Dark is a PSA video available for public outreach through fulldome theaters as well as conventional venues (classroom, lecture hall, YouTube, Vimeo). It was created by Loch Ness Productions for the International Dark Sky Association. It explains problems caused by light pollution, which targets astronomy, health, and the environment. Losing the Dark also suggests ways people can implement "wise lighting" practices to help mitigate light pollution. The video is available free of charge for outreach professionals in planetarium facilities (both fulldome and classical), science centers, classroom, and other outreach venues, and has been translated into 13 languages. It is available via download, USB key (at cost), and through online venues. This paper summarizes the program's outreach to more than a thousand fulldome theaters, nearly 100,000 views via four sites on Youtube and Vimeo,a number of presentations at other museum and classroom facilities, and shares some preliminary metrics and commentary from users.

The aim of the present study was to identify game-related statistics that differentiate winning and losing teams according to game location. The sample included 306 games of the 2004-2005 regular season of the Spanish professional men's league (ACB League). The independent variables were game location (home or away) and game result (win or loss). The game-related statistics registered were free throws (successful and unsuccessful), 2- and 3-point field goals (successful and unsuccessful), offensive and defensive rebounds, blocks, assists, fouls, steals, and turnovers. Descriptive and inferential analyses were done (one-way analysis of variance and discriminate analysis). The multivariate analysis showed that winning teams differ from losing teams in defensive rebounds (SC = .42) and in assists (SC = .38). Similarly, winning teams differ from losing teams when they play at home in defensive rebounds (SC = .40) and in assists (SC = .41). On the other hand, winning teams differ from losing teams when they play away in defensive rebounds (SC = .44), assists (SC = .30), successful 2-point field goals (SC = .31), and unsuccessful 3-point field goals (SC = -.35). Defensive rebounds and assists were the only game-related statistics common to all three analyses.

The Memory Trace Supporting Lose-Shift Responding Decays Rapidly after Reward Omission and Is Distinct from Other Learning Mechanisms in Rats.

Science.gov (United States)

Gruber, Aaron J; Thapa, Rajat

2016-01-01

The propensity of animals to shift choices immediately after unexpectedly poor reinforcement outcomes is a pervasive strategy across species and tasks. We report here that the memory supporting such lose-shift responding in rats rapidly decays during the intertrial interval and persists throughout training and testing on a binary choice task, despite being a suboptimal strategy. Lose-shift responding is not positively correlated with the prevalence and temporal dependence of win-stay responding, and it is inconsistent with predictions of reinforcement learning on the task. These data provide further evidence that win-stay and lose-shift are mediated by dissociated neural mechanisms and indicate that lose-shift responding presents a potential confound for the study of choice in the many operant choice tasks with short intertrial intervals. We propose that this immediate lose-shift responding is an intrinsic feature of the brain's choice mechanisms that is engaged as a choice reflex and works in parallel with reinforcement learning and other control mechanisms to guide action selection.

Living Joyfully after Losing Social Hope: Kierkegaard and Chrétien on Selfhood and Eschatological Expectation

Directory of Open Access Journals (Sweden)

J. Aaron Simmons

2017-02-01

Full Text Available In this essay, I offer an existential-phenomenological consideration of what it might look like to live joyfully after losing social hope. Using the example of the widespread hopelessness that many are feeling in light of the election of Donald Trump, I suggest that the danger of losing hope is that we can also lose our selfhood in the process. In order to develop a conception of “eschatological hope” that would be resistant to the loss of such social and political expectations, I draw specifically on Søren Kierkegaard’s notion that “the expectancy of faith is victory,” and Jean-Louis Chrétien’s idea of “the unhoped for,” in order to develop a model of hope that remains when it seems like all other hope has been lost. Rather than being overcome by anxiety about the future, eschatological hope fosters joy in the present.

Using micro-contexts to describe a writing process in Estonian as a second language across proficiency levels

Olga Pastuhhova

2015-04-01

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

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

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

It is a common belief that the shift to digital imaging some 20 years ago helped medical image exchange and got rid of any potential image loss that was happening with printed image films. Unfortunately, this is not the case: despite the most recent advances in digital imaging, most hospitals still keep losing their imaging data, with these losses going completely unnoticed. As a result, not only does image loss affect the faith in digital imaging but it also affects patient diagnosis and dai...

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

Directory of Open Access Journals (Sweden)

Jaana Eigi

2018-03-01

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

Winning and losing tree species of reassembly in Minnesota's mixed and broadleaf forests.

Directory of Open Access Journals (Sweden)

Brice B Hanberry

Full Text Available We examined reassembly of winning and losing tree species, species traits including shade and fire tolerance, and associated disturbance filters and forest ecosystem types due to rapid forest change in the Great Lakes region since 1850. We identified winning and losing species by changes in composition, distribution, and site factors between historical and current surveys in Minnesota's mixed and broadleaf forests. In the Laurentian Mixed Forest, shade-intolerant aspen replaced shade-intolerant tamarack as the most dominant tree species. Fire-tolerant white pine and jack pine decreased, whereas shade-tolerant ashes, maples, and white cedar increased. In the Eastern Broadleaf Forest, fire-tolerant white oaks and red oaks decreased, while shade-tolerant ashes, American basswood, and maples increased. Tamarack, pines, and oaks have become restricted to sites with either wetter or sandier and drier soils due to increases in aspen and shade-tolerant, fire-sensitive species on mesic sites. The proportion of shade-tolerant species increased in both regions, but selective harvest reduced the applicability of functional groups alone to specify winners and losers. Harvest and existing forestry practices supported aspen dominance in mixed forests, although without aspen forestry and with fire suppression, mixed forests will transition to a greater composition of shade-tolerant species, converging to forests similar to broadleaf forests. A functional group framework provided a perspective of winning and losing species and traits, selective filters, and forest ecosystems that can be generalized to other regions, regardless of species identity.

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

To examine the health care-related experiences of individuals who have lost their FPs. A qualitative design using phenomenology. Southwestern Ontario. Eighteen participants (9 women and 9 men, with a mean age of 48.9 years) from urban or rural areas who had lost their FPs. Semistructured interviews were conducted, which were audiotaped and transcribed verbatim. An iterative approach using immersion and crystallization was employed for analysis. Participants reported having lost their FPs because of reasons specific to their physicians (eg, illness, retirement, career change) or system issues (eg, poor remuneration for FPs, cutbacks in health care leading to physician emigration). Participants described feelings of loss, abandonment, frustration, and anger related to losing their physicians. They expressed concerns about the difficulty of getting prescription medications, lack of continuity of care related to medical records, and preventive care. They faced considerable hurdles in accessing primary health care, turning to walk-in clinics and emergency departments despite concerns about quality and fragmentation of care. Some of those with chronic medical conditions prevailed upon specialists to help meet primary health care needs. Losing access to FPs evoked a variety of strong feelings among these participants. They engaged in a number of strategies to meet their primary care needs but not without reservations. In a health care system appropriately built on primary health care, the lack of access to FPs is regarded as the loss of a basic right to care.

To characterize a rare inherited hypokalemic salt-losing tubulopathy with linkage to chromosome 1p31. We conducted a retrospective analysis of the clinical data for 7 patients in whom cosegregation of the disease with chromosome 1p31 had been demonstrated. In addition, in 1 kindred, prenatal diagnosis in the second child was established, allowing a prospective clinical evaluation. Clinical presentation of the patients was homogeneous and included premature birth attributable to polyhydramnios, severe renal salt loss, normotensive hyperreninemia, hypokalemic alkalosis, and excessive hyperprostaglandin E-uria, which suggested the diagnosis of hyperprostaglandin E syndrome/antenatal Bartter syndrome. However, the response to indomethacin was only poor, accounting for a more severe variant of the disease. The patients invariably developed chronic renal failure. The majority had extreme growth retardation, and motor development was markedly delayed. In addition, all patients turned out to be deaf. The hypokalemic salt-losing tubulopathy with chronic renal failure and sensorineural deafness represents not only genetically but also clinically a disease entity distinct from hyperprostaglandin E syndrome/antenatal Bartter syndrome. A pleiotropic effect of a single gene defect is most likely causative for syndromic hearing loss.

The ketogenic diet is a valuable therapy for patients with intractable epilepsy, but it can result in a variety of complications that sometimes limits its usefulness. Hypoproteinemia is one of the common adverse effects of this diet, although the underling mechanism is largely unknown except for the diet's reduced protein intake. Only one case of protein-losing enteropathy during the ketogenic diet has been reported. A previously healthy 9-year-old girl experienced fever for 5 days then suddenly developed convulsive seizures that subsequently evolved to severe refractory status epilepticus. After multiple antiepileptic drugs failed to improve the patient's condition, we introduced the ketogenic diet. Although her seizures diminished, her course was complicated by hypoproteinemia. An abdominal dynamic scintigraphy and colonoscopy findings indicated protein-losing enteropathy with nonspecific mucosal inflammation. Her nutritional status deteriorated; thus, we discontinued the ketogenic diet. Her nutritional status gradually improved, whereas her seizures increased. Hypoproteinemia during the ketogenic diet is common, but the underlying etiologies are not well understood. Abdominal dynamic scintigraphy could be valuable for clarifying the etiology of hypoproteinemia during the ketogenic diet. Copyright © 2015 Elsevier Inc. All rights reserved.

Organizational culture based on the example of an Estonian hospital.

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

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

Hypnotic induction in dentistry--coping with the fear of losing control (autonomy): a brief communication.

Science.gov (United States)

Kleinhauz, M; Eli, I

1991-07-01

A common cause of stress among dental patients is the patient's fear of losing control in face of the "helplessness provoking" dental situation. Although hypno-relaxation and hypnosis serve as efficient tools to aid in the administration of dental treatment to such patients, some of them may view hypnosis as a further relinquishing of control to the hypnotist and thus resist hypnotic induction, despite their willingness to try to use hypnosis for therapeutic reasons. To avoid this resistance, a "self-control" induction method is suggested that enables the patient to remain in control throughout the process. This technique minimizes the threat of losing one's autonomy and thus enables treatment of these patients.

2013-01-01

We examined reassembly of winning and losing tree species, species traits including shade and fire tolerance, and associated disturbance filters and forest ecosystem types due to rapid forest change in the Great Lakes region since 1850. We identified winning and losing species by changes in composition, distribution, and site factors between historical and current surveys in Minnesota’s mixed and broadleaf forests. In the Laurentian Mixed Forest, shade-intolerant aspen replaced shade-intolerant tamarack as the most dominant tree species. Fire-tolerant white pine and jack pine decreased, whereas shade-tolerant ashes, maples, and white cedar increased. In the Eastern Broadleaf Forest, fire-tolerant white oaks and red oaks decreased, while shade-tolerant ashes, American basswood, and maples increased. Tamarack, pines, and oaks have become restricted to sites with either wetter or sandier and drier soils due to increases in aspen and shade-tolerant, fire-sensitive species on mesic sites. The proportion of shade-tolerant species increased in both regions, but selective harvest reduced the applicability of functional groups alone to specify winners and losers. Harvest and existing forestry practices supported aspen dominance in mixed forests, although without aspen forestry and with fire suppression, mixed forests will transition to a greater composition of shade-tolerant species, converging to forests similar to broadleaf forests. A functional group framework provided a perspective of winning and losing species and traits, selective filters, and forest ecosystems that can be generalized to other regions, regardless of species identity.

The Eastern Tropical Pacific (ETP) hosts two of the world's three Oxygen Deficient Zones (ODZs), large bodies of suboxic water that are subject to high rates of water column denitrification. In the mean, these two ODZs are responsible for about 15 to 40% of all fixed N loss in the ocean, but little is known about how this loss varies in time. Here, we use a hindcast simulation with the ocean component of the NCAR Community Earth System Model over the period 1960 to 2009 to show that Pacific ODZ structures and their associated rates of N-loss are subject to strong climate forced variability and change. In particular, El Niño-Southern Oscillation (ENSO) drives large interannual variations in the rate of water column denitrification such that mature La Niña conditions exhibit peak denitrification rates that are up to 70% higher than the mean rates, and vice versa during El Niños. At the same time, we simulate large decadal trends in the rate of Pacific N-loss, which decreases by 10 Tg y-1 from the 1960s to the 1980s and subsequently increases by 30 Tg y-1 towards 2009. We demonstrate that this large variability is the result of wind-driven changes in circulation and isopycnal structure concurrently modifying the thermocline distribution of O2 and organic matter export. Finally, we show that the decadal trends in denitrification are recorded by the isotopic signature of particulate organic nitrogen in the ETP but that the interpretation of the signals is non trivial, reflecting both physical and biogeochemical changes as well as contamination by atmospheric pollutants.

Nanoporous Structure of Bone Matrix at Osteoporosis from Data of Atomic Force Microscopy and IR Spectroscopy

Full Text Available It was found that in an osteoporotic bone the fraction of nanosized pores decreases, the mineral phase amorphizes, hydrated shells around mineralized particles of the bone matrix thicken, and adhesion forces increase. This contributes to the formation of water clusters similar to bulk water clusters compared to the healthy bone tissue and leads to the accumulation of more viscous liquid with increased intermolecular interaction forces in the pores of the bone matrix. Given this, the rates of chemical reactions proceeding in the water phase of ultrathin channels of general parts of collagen fibrils decrease. Ultimately, nanopores of collagen-apatite interfaces lose, to a certain extent, the capability of catalyzing the hydroxyapatite crystallization.

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

Karusoo’s biographical theatre has gathered momentum and assumed a more

Physical activity is an integral part of weight control programs, but recommended amounts vary. The objectives of this study were to describe the prevalence and characteristics of those who reported using exercise as a weight loss strategy (N=14,716), and to determine the prevalence of meeting various institutionally recommended levels of physical activity (N=8538) among that population. Data were obtained from the 1998 National Health Interview Survey, a face-to-face nationally representative household interview. Questions on leisure-time physical activity were analyzed using SUDAAN. Among those who reported trying to lose weight, 55% reported using exercise as a weight loss strategy alone, and of those, 58% reported eating fewer calories. The prevalence of using exercise as a weight loss strategy was directly associated with education and inversely associated with age and body mass index. Among those who reported using exercise as a weight loss strategy, 57% met the minimal 1998 National Institutes of Health recommendation of >or=150 min.wk; 46% met the lower end of the 2001 American College of Sports Medicine recommendation of 200 min.wk; and 30% met the upper end for 300 min.wk. Only 19% met the 2002 Institute of Medicine recommendation of 420 min.wk. Despite the importance of physical activity in a weight loss program, only about half of the persons trying to lose weight reported using exercise. Even among those, only slightly more than half met the minimal recommendations for physical activity. Efforts are needed to aid those trying to lose weight to incorporate appropriate levels of physical activity into their weight loss strategy.

Full Text Available The aim of the present study was to analyze men's football competitions, trying to identify which game-related statistics allow to discriminate winning, drawing and losing teams. The sample used corresponded to 380 games from the 2008-2009 season of the Spanish Men's Professional League. The game-related statistics gathered were: total shots, shots on goal, effectiveness, assists, crosses, offsides commited and received, corners, ball possession, crosses against, fouls committed and received, corners against, yellow and red cards, and venue. An univariate (t-test and multivariate (discriminant analysis of data was done. The results showed that winning teams had averages that were significantly higher for the following game statistics: total shots (p < 0.001, shots on goal (p < 0.01, effectiveness (p < 0.01, assists (p < 0.01, offsides committed (p < 0.01 and crosses against (p < 0.01. Losing teams had significantly higher averages in the variable crosses (p < 0.01, offsides received (p < 0. 01 and red cards (p < 0.01. Discriminant analysis allowed to conclude the following: the variables that discriminate between winning, drawing and losing teams were the total shots, shots on goal, crosses, crosses against, ball possession and venue. Coaches and players should be aware for these different profiles in order to increase knowledge about game cognitive and motor solicitation and, therefore, to evaluate specificity at the time of practice and game planning

Fine particle deposition and streambed clogging affect many ecological and biogeochemical processes, but little is known about the effects of groundwater flow into and out of rivers on clogging. We evaluated the effects of losing and gaining flow on the deposition of suspended kaolinite clay particles in a sand streambed and the resulting changes in rates and patterns of hyporheic exchange flux (HEF). Observations of clay deposition from the water column, clay accumulation in the streambed sediments, and water exchange with the bed demonstrated that clay deposition in the bed substantially reduced both HEF and the size of the hyporheic zone. Clay deposition and HEF were strongly coupled, leading to rapid clogging in areas of water and clay influx into the bed. Local clogging diverted exchanged water laterally, producing clay deposit layers that reduced vertical hyporheic flow and favored horizontal flow. Under gaining conditions, HEF was spatially constrained by upwelling water, which focused clay deposition in a small region on the upstream side of each bed form. Because the area of inflow into the bed was smallest under gaining conditions, local clogging required less clay mass under gaining conditions than neutral or losing conditions. These results indicate that losing and gaining flow conditions need to be considered in assessments of hyporheic exchange, fine particle dynamics in streams, and streambed clogging and restoration.

Full Text Available Gastric cancer with protein-losing gastroenteropathy is relatively rare worldwide. The most important problem for the treatment of these patients is their low nutritional status and protein level, which can cause severe postoperative complications. We report a 49-year-old Japanese female with a large gastric tumor and protein-losing gastroenteropathy successfully treated with neoadjuvant TS-1 combined with CDDP therapy. She had a type 5 tumor with partially cauliflower-like appearance. Her blood chemistry revealed low serum total protein (3.3 g/dl and low albumin (1.7 g/dl. She was additionally diagnosed with protein-losing gastroenteropathy based on 99mTc-human serum albumin scintigraphy. Initial neoadjuvant chemotherapy decreased the size of the tumor and led to a marked improvement in her serum protein levels. She then underwent a total gastrectomy and lymph node dissection (D2 with a combined resection of the spleen and gallbladder. Therefore, neoadjuvant chemotherapy may provide a safe treatment before definitive surgery for gastric cancer with protein-losing gastroenteropathy.

The majority of parenteral drug products are manufactured in glass vials with an elastomeric rubber stopper and a crimp cap. The vial sealing process is a critical process step during fill-and-finish operations, as it defines the seal quality of the final product. Different critical capping process parameters can affect rubber stopper defects, rubber stopper compression, container closure integrity, and also crimp cap quality. A sufficiently high force to remove the flip-off button prior to usage is required to ensure quality of the drug product unit by the flip-off button during storage, transportation, and until opening and use. Therefore, the final product is 100% visually inspected for lose or defective crimp caps, which is subjective as well as time- and labor-intensive. In this study, we sealed several container closure system configurations with different capping equipment settings (with corresponding residual seal force values) to investigate the torque moment required to turn the crimp cap. A correlation between torque moment and residual seal force has been established. The torque moment was found to be influenced by several parameters, including diameter of the vial head, type of rubber stopper (serum or lyophilized) and type of crimp cap (West(®) or Datwyler(®)). In addition, we measured the force required to remove the flip-off button of a sealed container closure system. The capping process had no influence on measured forces; however, it was possible to detect partially crimped vials. In conclusion, a controlled capping process with a defined target residual seal force range leads to a tight crimp cap on a sealed container closure system and can ensure product quality. The majority of parenteral drug products are manufactured in a glass vials with an elastomeric rubber stopper and a crimp cap. The vial sealing process is a critical process step during fill-and-finish operations, as it defines the seal quality of the final product. An adequate force

No-lose targets as an option to integrate non-Annex I countries in global emission reduction efforts. A game-theoretical analysis

Substantial greenhouse gas emission reductions of 50% and more below 1990 levels by 2050 are necessary, to limit mean temperature increase below 2 C above pre-industrial levels. While the Kyoto Protocol foresees emission reduction targets for Annex I countries only, current and projected greenhouse gas emissions, as well as the growing economic importance of emerging economies call for an integration of non-Annex I countries in global reduction efforts. No-lose targets set emission reduction targets and define incentives for meeting the target, in contrast to binding reduction targets that use penalties to ensure compliance. One form of incentive is the participation in an international emissions trading market. While a few conceptual and quantitative analyses of no-lose targets can be found in the literature, economic analyses have not been carried out so far. In this thesis, two theoretical frameworks are introduced to analyze the potential of no-lose targets to contribute to global emission reduction efforts. First, a two-player, two-stage model is developed to model a non-Annex I country's participation decision and derive the contribution to global emission reductions. Then a two-player participation game is introduced to analyze the effects that the participation decision of one non-Annex I country has on another non-Annex I country also facing a no-lose target. Two market forms, a perfectly competitive market, and a market with market power on the side of the non-Annex I country are analyzed. In order to complement the highly stylized theoretical frameworks, a quantitative analysis applying marginal abatement cost curves is conducted to estimate the contribution of no-lose targets to reaching the 2 C target. The analyses show that no-lose targets can result in substantial contributions from non-Annex I countries to global emission reductions, in particular if the reduction potential in the non-Annex I countries is large, compared to that of the Annex I

Protein losing enteropathy secondary to a pulmonary artery stent

Full Text Available A 2-year-old patient with hypoplastic left heart syndrome presented 6 months following Fontan completion with protein-losing enteropathy (PLE. He had undergone stent implantation in the left pulmonary artery after the Norwood procedure, followed by redilation of the stent prior to Fontan completion. Combined bronchoscopic and catheterization studies during spontaneous breathing confirmed left bronchial stenosis behind the stent, and diastolic systemic ventricular pressure during expiration of 25 mm Hg. We postulate that the stent acts as a valve, against which the patient generates high expiratory pressures, which are reflected in the ventricular diastolic pressure. This may be the cause of PLE.

Fuel Cooling in Absence of Forced Flow at Shutdown Condition with PHTS Partially Drained

During the plant outage for maintenance on primary side (e.g. for the main Heat Transport System pumps maintenance, the Steam Generators inspection), there are situations which require the primary heat transport system (HTS) drainage to a certain level for opening the circuit. The primary fuel heat sink for this configuration is provided by the shutdown cooling system (SDCS). In case of losing the forced cooling (e.g. due to the loss of SDCS, design basis earthquake-DBE), flow conditions in the reactor core may become stagnant. Inside the fuel channels, natural circulation phenomena known as Intermittent Buoyancy Induced Flow (IBIF) will initiate, providing an alternate heat sink mechanism for the fuel. However, this heat sink is effective only for a limited period of time (recall time). The recall time is defined as the elapsed time until the water temperature in the HTS headers exceeds a certain limit. Until then, compensatory measures need to be taken (e.g. by re-establishing the forced flow or initiate Emergency Core Cooling system injection) to preclude fuel failures. The present paper briefly presents the results of an analysis performed to demonstrate that fuel temperature remains within acceptable limits during IBIF transient. One of the objectives of this analysis was to determine the earliest moment since the reactor shut down when maintenance activities on the HTS can be started such that IBIF is effective in case of losing the forced circulation. The resulting peak fuel sheath and pressure tube temperatures due to fuel heat up shall be within the acceptable limits to preclude fuel defect or fuel channel defects.Thermalhydraulic circuit conditions were obtained using a CATHENA model for the primary side of HTS (drained to a certain level), an ECC system model and a system model for SDCS. A single channel model was developed in GOTHIC code for the fuel assessment analysis. (author)

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

Science.gov (United States)

Tuuling, Igor; Flodén, Tom

2016-06-01

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

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

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

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

Using social network analysis method,this paper made an empirical study on growth of evil forces in land requisition and relocation in City G of Hubei Province. It obtained following results:(i) lawless developers and inefficient public security organs form interested parties of evil forces. Besides,the inward closeness centrality of evil forces is high,manifesting that evil forces independently possess decentralized power of network and have unscrupulous behavior in land requisition and relocation to a certain extent.(ii) Activities of evil forces have complicated spatial correlation and their geographical distribution is uneven,taking on irregular characteristics. In the field of land requisition and relocation,some evil forces are expandi Xng and spreading,while other forces are relatively weak. In conclusion,growth of evil forces comes from premeditation and collaboration of lawless developers,lack of functions and weak attack of public security organs; growth of evil forces has periodic changes,when in power,they will take opportunity to expand,while losing power,they will hide or even disappear.

There are few reports on successful high-dose spironolactone treatment of refractory protein-losing enteropathy (PLE) caused by Fontan procedure. We report successful diuretics treatment with spironolactone and furosemide at standard dose, of refractory PLE in a patient with Noonan syndrome and repaired congenital heart disease. This is the first successful application of diuretics treatment in a patient with refractory PLE without Fontan procedure. This case illustrates that diuretics treatment can be the first-line treatment of PLE regardless of the causative physiology, and can be effective in refractory PLE with Noonan syndrome. © 2015 Japan Pediatric Society.

From Losing to Loss: Exploring the Expressive Capacities of Videogames Beyond Death as Failure

Directory of Open Access Journals (Sweden)

Sabine Harrer

2013-12-01

Full Text Available In games, loss is as ubiquitous as it is trivial. One reason for this has been found in the established convention of on-screen character death as a signifier for failure (Klastrup 2006; Grant 2011; Johnson 2011. If that’s all that games have to offer in terms of addressing an existential trope of human experience, the worried protectionist concludes, shouldn’t we dismiss this intrinsically flat medium as inferior to more established media forms such as film or literature? (Ebert 2010. Contrary to this view, this paper discusses gameplay examples that shed light on how this medium might leverage its expressive resources to arrive at rich representations of loss. First, the notion of loss implied in Sigmund Freud’s work “Mourning and Melancholia” (1917 will be discussed in relation to losing in games. Looking at procedurality, fictional alignment and experiential metaphor as three expressive gameplay devices identified by Doris Rusch (2009 will help explain the expressive shortcoming of losing and lay out what is at stake with profound gameplay expression. Moreover, it will serve as the keywords structuring the following analysis of three videogames, Final Fantasy VII (1997, Ico (2001 and Passage (2007, and their design decisions fostering deep representations of loss. Keeping the Freudian notion of loss in mind, we can trace its repercussions on the three expressive dimensions respectively. Following a separate analysis of each gameplay example, the last section will discuss some commonalities and differences and arrive at the identification of desired object, permanent disruption and linearity as design aspects modeling loss in more compelling ways than losing.

Win-stay-lose-learn promotes cooperation in the spatial prisoner's dilemma game.

Directory of Open Access Journals (Sweden)

Yongkui Liu

Full Text Available Holding on to one's strategy is natural and common if the later warrants success and satisfaction. This goes against widespread simulation practices of evolutionary games, where players frequently consider changing their strategy even though their payoffs may be marginally different than those of the other players. Inspired by this observation, we introduce an aspiration-based win-stay-lose-learn strategy updating rule into the spatial prisoner's dilemma game. The rule is simple and intuitive, foreseeing strategy changes only by dissatisfied players, who then attempt to adopt the strategy of one of their nearest neighbors, while the strategies of satisfied players are not subject to change. We find that the proposed win-stay-lose-learn rule promotes the evolution of cooperation, and it does so very robustly and independently of the initial conditions. In fact, we show that even a minute initial fraction of cooperators may be sufficient to eventually secure a highly cooperative final state. In addition to extensive simulation results that support our conclusions, we also present results obtained by means of the pair approximation of the studied game. Our findings continue the success story of related win-stay strategy updating rules, and by doing so reveal new ways of resolving the prisoner's dilemma.

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

Waldmann's disease: a rare cause of protein losing enteropathy in an adult patient

Directory of Open Access Journals (Sweden)

Cláudio Martins

Full Text Available Primary intestinal lymphangiectasia or Waldmann's disease is an uncommon cause of protein losing enteropathy with an unknown etiology and is usually diagnosed during childhood. It is characterized by dilation and leakage of intestinal lymph vessels leading to hypoalbuminemia, hypogammaglobulinemia and lymphopenia. Differential diagnosis should include erosive and non-erosive gastrointestinal disorders, conditions involving mesenteric lymphatic obstruction and cardiovascular disorders that increase central venous pressure. Since there are no accurate serological or radiological available tests, enteroscopy with histopathological examination based on intestinal biopsy specimens is currently the gold standard diagnostic modality of intestinal lymphangiectasia. We report a rare case of a primary intestinal lymphangiectasia in a 60-year-old Caucasian female who presented with asymptomatic hypoalbuminemia and hypogammaglobulinemia. After the diagnosis of a protein losing enteropathy, the patient underwent an enteroscopy and biopsies were taken, whose histological examination confirmed dilated intestinal lymphatics with broadened villi of the small bowel. Secondary causes of intestinal lymphangiectasia were excluded and the diagnosis of Waldmann's disease was recorded. The patient was put on a high-protein and low-fat diet with medium-chain triglyceride supplementation with improvement.

Losing images in digital radiology: more than you think.

Oglevee, Catherine; Pianykh, Oleg

It is a common belief that the shift to digital imaging some 20 years ago helped medical image exchange and got rid of any potential image loss that was happening with printed image films. Unfortunately, this is not the case: despite the most recent advances in digital imaging, most hospitals still keep losing their imaging data, with these losses going completely unnoticed. As a result, not only does image loss affect the faith in digital imaging but it also affects patient diagnosis and daily quality of clinical work. This paper identifies the origins of invisible image losses, provides methods and procedures to detect image loss, and demonstrates modes of action that can be taken to stop the problem from happening.

As exemplified by the situation in Cambodia, disease specific (vertical) health programmes are often favoured when the health system is fragile. The potential of such an approach to impede strengthening of primary healthcare services has been studied from a health systems perspective in terms of access and quality of care. In this bottom-up, qualitative study we investigate patient and community member experiences of health services when a strong tuberculosis (TB) programme is embedded into a relatively underutilized primary healthcare system. We conducted six gender-stratified community focus group discussions (n = 49) and seven mixed-gender focus group discussions with TB patients (n = 45) in three provinces located in urban, peri-urban and rural areas of Cambodia. Our analysis of health-seeking behaviour and experiences for TB and TB-like illness indicates that building a strong vertical TB control programme has had numerous benefits, including awareness of typical symptoms and need to seek care early; confidence in free TB services at public facilities; and willingness to complete treatment. However, there was a clear dichotomy in experiences and behaviour with respect to care-seeking for less severe illness at primary health services, which were generally avoided owing to access barriers and perceived poor quality. The tendency to delay seeking health care until the development of severe symptoms clearly indicative of TB is a major barrier to early diagnosis and treatment of TB. Our study indicates that an imbalance in the strength of vertical and primary health services could be a lose-lose situation as this impedes improvements in health system functioning and constrains progress of vertical disease control programmes. © The Author 2017.

Winning and losing: an evolutionary approach to mood disorders and their therapy.

Science.gov (United States)

Sloman, Leon; Sturman, Edward D; Price, John S

2011-06-01

To advance a new evolutionary model that examines the effects of winning and losing on mood and physiological variables. Previous studies have focused on the involuntary defeat strategy in de-escalating conflict. Here, we propose that there also exists an involuntary winning strategy (IWS) that is triggered by success and characterized by euphoria and increased self-confidence. It motivates efforts to challenge, and promotes reconciliation. Previous studies are presented, including data on student athletes, demonstrating the impact of winning and losing on mood. Winning is consistently shown to be related to physiological changes such as increased testosterone and serotonin levels in primates. It reliably leads to mood changes that serve to motivate winners to continue their competitive efforts. When the IWS functions optimally, success leads to success in an adaptive cycle. Over time, the initial differences between the winners and losers of agonistic encounters become magnified in a process known as difference amplification. As a result of assortative mating, the children of people who have entered into an adaptive cycle will inherit traits from both parents that will, in turn, give them an increased competitive advantage. In this manner, difference amplification could have accelerated human evolution by natural selection. Vignettes of clinical interventions are also used to illustrate therapeutic strategies designed to disrupt maladaptive cycles and promote adaptive behaviour.

Behavioural and neural modulation of win-stay but not lose-shift strategies as a function of outcome value in Rock, Paper, Scissors.

Science.gov (United States)

Forder, Lewis; Dyson, Benjamin James

2016-09-23

Competitive environments in which individuals compete for mutually-exclusive outcomes require rational decision making in order to maximize gains but often result in poor quality heuristics. Reasons for the greater reliance on lose-shift relative to win-stay behaviour shown in previous studies were explored using the game of Rock, Paper, Scissors and by manipulating the value of winning and losing. Decision-making following a loss was characterized as relatively fast and relatively inflexible both in terms of the failure to modulate the magnitude of lose-shift strategy and the lack of significant neural modulation. In contrast, decision-making following a win was characterized as relatively slow and relatively flexible both in terms of a behavioural increase in the magnitude of win-stay strategy and a neural modulation of feedback-related negativity (FRN) and stimulus-preceding negativity (SPN) following outcome value modulation. The win-stay/lose-shift heuristic appears not to be a unified mechanism, with the former relying on System 2 processes and the latter relying on System 1 processes. Our ability to play rationally appears more likely when the outcome is positive and when the value of wins are low, highlighting how vulnerable we can be when trying to succeed during competition.

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

The purpose of this study was to evaluate Soft Coated Wheaten Terriers (SCWTs) affected with protein-losing enteropathy (PLE) or protein-losing nephropathy (PLN) or both for allergy to food. We performed gastroscopic food-sensitivity testing, a provocative dietary trial, and measurement of fecal immunoglobulin E (IgE) in 6 SCWTs affected with PLE or PLN or both. Positive gastroscopic food-sensitivity test reactions were noted in 5 of 6 dogs. Positive reactions were found to milk in 4 dogs, to lamb in 2 dogs, and to wheat and chicken each in 1 dog. Adverse reactions to food (diarrhea, vomiting, or pruritus) were detected in all 6 dogs during the provocative dietary trial. Adverse reactions were found to corn in 5 dogs, to tofu in 3 dogs, to cottage cheese in 2 dogs, to milk in 2 dogs, to farina cream of wheat in 2 dogs, and to lamb in 2 dogs. Serum albumin concentrations significantly decreased and fecal alpha1-protease inhibitor concentration significantly increased 4 days after the provocative trial when compared with baseline values. Antigen-specific fecal IgE varied throughout the provocative trial, with peak levels following ingestion of test meals. We conclude that food hypersensitivities are present in SCWTs affected with the syndrome of PLE/PLN. Mild inflammatory bowel disease was already established in the 6 SCWTs of this report at the time of study, making it impossible to determine if food allergies were the cause or result of the enteric disease.

Vaping to lose weight: Predictors of adult e-cigarette use for weight loss or control.

Some traditional cigarette smokers are motivated to smoke to lose weight or control their weight. The current study evaluated whether a subset of adult e-cigarette users reported vaping to lose or control their weight and examined potential predictors of vaping for weight management. Adult e-cigarette users (n=459) who reported wanting to lose weight or maintain their weight completed an anonymous online survey. Participants reported on demographics, vaping frequency, e-cigarette nicotine content, cigarette smoking status, preferred e-cigarette/e-liquid flavors, current weight status (i.e., overweight, underweight), use of dieting strategies associated with anorexia and bulimia, lifetime history of binge eating, self-discipline, and impulse control. Binary logistic regression was used to examine whether vaping for weight loss/control was associated with the aforementioned variables. Participants who reported vaping for weight loss/control (13.5%) were more likely to vape frequently (adjOR=1.15; 95% CI [1.00, 1.31]); be overweight (adjOR=2.80; [1.33, 5.90]); restrict calories (adjOR=2.23; [1.13, 4.42]); have poor impulse control (adjOR=0.59; [0.41, 0.86]); and prefer coffee- (adjOR=2.92; [1.47, 5.80]) or vanilla-flavored e-liquid (adjOR=7.44; [1.56, 36.08]). A subset of adult e-cigarette users reported vaping for weight loss/control, raising concerns about expanded, scientifically unsubstantiated uses of e-cigarettes. Identifying where individuals obtain information about vaping for weight loss (e.g., e-cigarette ads, Internet) and whether weight-related motives promote e-cigarette initiation among e-cigarette naïve individuals is important to informing regulatory efforts. Further research also is needed to better understand the link between e-liquid flavors and weight loss motivations. Copyright © 2016 Elsevier Ltd. All rights reserved.

Particle Tracking Model for Suspended Sediment Transport and Streambed Clogging Under Losing and Gaining Conditions

Exchange of mass, momentum and energy between surface water and groundwater is a driving factor for the biology, ecology and chemistry of rivers and water bodies in general. Nonetheless, this exchange is dominated by different factors like topography, bed morphology, and large-scale hydraulic gradient. In the particular case of fine sediments like clay, conservative tracer modeling is impossible because they are trapped in river beds for long periods, thus the normal advection dispersion approach leads to errors and results do not agree with reality. This study proposes a numerical particle tracking model that represents the behavior of kaolinite in a sand flume, and how its deposition varies according to different flow conditions, namely losing and gaining flow. Since fine particles do not behave like solutes, kaolinite dynamics are represented using settling velocity and a filtration coefficient allowing the particles to be trapped in the bed. This approach allows us to use measurable parameters directly related with the fine particle features as size and shape, and hydraulic parameters. Results are then compared with experimental results from lab experiments obtained in a recirculating flume, in order to assess the impact of losing and gaining conditions on sediment transport and deposition. Furthermore, our model is able to identify the zones where kaolinite deposition concentrates over the flume due to the bed geometry, and later relate these results with clogging of the bed and hence changes in the bed's hydraulic conductivity. Our results suggest that kaolinite deposition is higher under losing conditions since the vertical velocity of the flow is added to the deposition velocity of the particles modeled. Moreover, the zones where kaolinite concentrates varies under different flow conditions due to the difference in pressure and velocity in the river bed.

Reaction pathways of producing and losing particles in atmospheric pressure methane nanosecond pulsed needle-plane discharge plasma

In this work, a two-dimensional fluid model is built up to numerically investigate the reaction pathways of producing and losing particles in atmospheric pressure methane nanosecond pulsed needle-plane discharge plasma. The calculation results indicate that the electron collisions with CH4 are the key pathways to produce the neutral particles CH2 and CH as well as the charged particles e and CH3+. CH3, H2, H, C2H2, and C2H4 primarily result from the reactions between the neutral particles and CH4. The charge transfer reactions are the significant pathways to produce CH4+, C2H2+, and C2H4+. As to the neutral species CH and H and the charged species CH3+, the reactions between themselves and CH4 contribute to substantial losses of these particles. The ways responsible for losing CH3, H2, C2H2, and C2H4 are CH3 + H → CH4, H2 + CH → CH2 + H, CH4+ + C2H2 → C2H2+ + CH4, and CH4+ + C2H4 → C2H4+ + CH4, respectively. Both electrons and C2H4+ are consumed by the dissociative electron-ion recombination reactions. The essential reaction pathways of losing CH4+ and C2H2+ are the charge transfer reactions.

People say they enjoy both seeing a preferred social group succeed and seeing an adversary social group fail. At the same time, they state they dislike seeing a preferred social group fail and seeing an adversary social group succeed. The current magnetic resonance imaging study investigated whether-and if so, how-such similarities in reported feeling states are reflected in neural activities. American football fans anticipated success and failure situations for their favorite or their adversary teams. The data support the idea that feeling similarities and divergences expressed in verbal reports carry with them significant neural similarities and differences, respectively. Desired (favorite team likely to win and adversary team likely to lose) rather than undesired (favorite team likely to lose and adversary team likely to win) outcomes were associated with heightened activity in the supramarginal gyrus, posterior cingulate cortex, insula, and cerebellum. Precuneus activity additionally distinguished anticipated desirable outcomes for favorite versus adversary teams. Copyright © 2014 Elsevier Ltd. All rights reserved.

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

Full Text Available Abstract Introduction Burkitt lymphoma and B cell lymphomas in childhood may arise in many atypical locations, which on rare occasions can include gastric mucosa. A case of primary gastric Burkitt lymphoma is described in a child presenting as a protein-losing enteropathy, including the direct monitoring of the disease response by sequential endoscopic biopsy and molecular analysis. Case presentation We report a 9-year-old boy who presented with gross oedema, ascites and respiratory distress caused by a protein-losing enteropathy. Initial imaging investigations were non-diagnostic but gastroduodenal endoscopy revealed massive involvement of the gastric mucosa with a primary Burkitt lymphoma. His subsequent clinical progress and disease response were monitored directly by endoscopy and he remains in clinical remission 4 years after initial diagnosis. Conclusions This is the first case report of primary Burkitt lymphoma presenting as a protein-losing enteropathy. The clinical course and progress of the patient were monitored by sequential endoscopic biopsy, histology and molecular analysis by fluorescence in situ hybridisation.

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

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

Background Protein-losing enteropathy (PLE) is a disorder characterized by abnormal and often profound enteric protein loss. It’s relatively uncommon complication of Fontan and other complex congenital heart disease (CCHD) procedures. Because of the complexity and rarity of this disease process, the pathogenesis and pathophysiology of protein-losing enteropathy remain poorly understood, and attempts at treatment seldom yield long-term success. Aim of presentation is to describe single centre experience in diagnosis, evaluation, management and treatment of children with protein-losing enteropathy after Fontan and other CCHD procedures in the current era and in centre with limited human and technical resources, follows with a comprehensive review of protein-losing enteropathy publications, and concludes with suggestions for prevention and treatment. Material and methodology Retrospectively we analyzed patients with CCHD and protein-losing enteropathy in our institution, starting from January 2000 to December 2012. The including criteria were age between two and 17 years, to have a complex congenital heart disease and available complete documentation of cardiac surgery under cardiopulmonary bypass. Results Of all patients we evaluated 18 cases with protein-losing enteropathy, aged 6 to 19 years (mean 14±9); there were three children who had undergone screening procedure for D-transposition, one Tetralogy of Fallot, and remaining 14 patients had undergone Fontan procedures; (anatomic diagnosis are: six with tricuspid atresia, seven with d-transposition, double outlet right ventricle and pulmonary atresia and two with hypoplastic left heart syndrome). The diagnosis of protein-losing enteropathy was made at median age of 5.6 years, ranging from 13 months to 15 years. Diagnosis was made using alpha 1-antitrypsin as a gold marker in stool. By physical examination in 14 patients edema was found, in three ascites, and six patients had pleural effusion. Laboratory findings

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

Tekkel, M.; Rahu, M.; Veidebaum, T.

1997-01-01

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

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

Frequency-locked detector (FLD) has been widely utilized in tracking loops of Global Positioning System (GPS) receivers to indicate their locking status. The relation between FLD and lock status has been seldom discussed. The traditional PLL experience is not suitable for FLL. In this paper, the threshold setting criteria for frequency-locked detector in the GPS receiver has been proposed by analyzing statistical characteristic of FLD output. The approximate probability distribution of frequency-locked detector is theoretically derived by using a statistical approach, which reveals the relationship between probabilities of frequency-locked detector and the carrier-to-noise ratio ( C / N ₀) of the received GPS signal. The relationship among mean-time-to-lose-lock (MTLL), detection threshold and lock probability related to C / N ₀ can be further discovered by utilizing this probability. Therefore, a theoretical basis for threshold setting criteria in frequency locked loops for GPS receivers is provided based on mean-time-to-lose-lock analysis.

Primary intestinal lymphangiectasia (PIL), also known as Waldmann's disease, is an exudative enteropathy resulting from morphologic abnormalities in the intestinal lymphatics. In this article, we describe a 12-year-old boy with PIL that led to protein-losing enteropathy characterized by diarrhea, hypoalbuminemia associated with edema (serum albumin level: 1.0 g/dL), and hypogammaglobulinemia (serum IgG level: 144 mg/dL). Severe hypoalbuminemia, electrolyte abnormalities, and tetany persisted despite a low-fat diet and propranolol. Everolimus (1.6 mg/m(2)/day) was added to his treatment as an antiangiogenic agent. With everolimus treatment, the patient's diarrhea resolved and replacement therapy for hypoproteinemia was less frequent. Hematologic and scintigraphy findings also improved (serum albumin level: 2.5 g/dL). There were no adverse reactions during the 12-month follow-up. To the best of our knowledge, this is the first report of everolimus use in a patient with PIL. Copyright © 2016 by the American Academy of Pediatrics.

Background Protein-losing enteropathy (PLE) is a disorder characterized by abnormal and often profound enteric protein loss. It’s relatively uncommon complication of Fontan and other complex congenital heart disease (CCHD) procedures. Because of the complexity and rarity of this disease process, the pathogenesis and pathophysiology of protein-losing enteropathy remain poorly understood, and attempts at treatment seldom yield long-term success. Aim of presentation is to describe single centre ...

Workshop on establishing institutional credibility for SEAB Task Force on Radioactive Waste Management

International Nuclear Information System (INIS)

1994-01-01

At the request of the Secretary of Energy Advisory Board's Task Force on Civilian Radioactive Waste Management, the National Research Council sponsored a workshop on Establishing Institutional Credibility. The purpose of the workshop was to (1) identify the range of available knowledge regarding the theoretical and conceptual issues of how institutions establish their credibility and legitimacy with key constituents, and (2) to help explore and clarify fundamental concepts in management theory related to these issues. The examination was to include what is known about how organizations establish, maintain, lose, and regain public trust and confidence. There was to be no attempt to develop consensus on these issues or to suggest particular courses of action. The workshop was held on October 24-25, 1991, in Denver, Colorado

Noonan syndrome, which is a multiple congenital disorder, may be associated with lymphatic abnormalities. Protein-losing enteropathy (PLE) developing in Noonan syndrome is rare. We performed transnodal lymphangiography by directly accessing bilateral inguinal nodes under ultrasound guidance in a 17-year-old female with PLE developing in Noonan syndrome to assess detailed anatomical findings regarding lymphatic vessels. There have been no reports on transnodal lymphangiography for Noonan syndrome. Post-lymphangiographic CT images revealed multiple lymphatic abnormalities and lipiodol extravasation into the duodenum and the proximal jejunum. Transnodal lymphangiography was easy and safe for PLE developing in Noonan syndrome, and post-lymphangiographic CT provided invaluable information.

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 short-term provision of ghrelin to patients with cancer indicates that there may be benefits from long-term provision of ghrelin for the palliative treatment of weight-losing cancer patients. This hypothesis was evaluated in a randomized, double-blind, phase 2 study. Weight-losing cancer patients with solid gastrointestinal tumors were randomized to receive either high-dose ghrelin treatment (13 microg/kg daily; n = 17 patients) or low-dose ghrelin treatment (0.7 microg/kg daily; n = 14 patients) for 8 weeks as a once-daily, subcutaneous injections. Appetite was scored on a visual analog scale; and food intake, resting energy expenditure, and body composition (dual x-ray absorpitometry) were measured before the start of treatment and during follow-up. Serum levels of ghrelin, insulin, insulin-like growth factor 1, growth hormone (GH), triglycerides, free fatty acids, and glucose were measured. Health-related quality of life, anxiety, and depression were assessed by using standardized methods (the 36-item Short Form Health Survey and the Hospital Anxiety and Depression Scale). Physical activity, rest, and sleep were measured by using a multisensor body monitor. Treatment groups were comparable at inclusion. Appetite scores were increased significantly by high-dose ghrelin analyzed both on an intent-to-treat basis and according to the protocol. High-dose ghrelin reduced the loss of whole body fat (P losing cancer patients with solid tumors supports host metabolism, improves appetite, and attenuates catabolism.

Heavy inertial particles in turbulent flows gain energy slowly but lose it rapidly

We present an extensive numerical study of the time irreversibility of the dynamics of heavy inertial particles in three-dimensional, statistically homogeneous, and isotropic turbulent flows. We show that the probability density function (PDF) of the increment, W (τ ) , of a particle's energy over a time scale τ is non-Gaussian, and skewed toward negative values. This implies that, on average, particles gain energy over a period of time that is longer than the duration over which they lose energy. We call this slow gain and fast loss. We find that the third moment of W (τ ) scales as τ3 for small values of τ . We show that the PDF of power-input p is negatively skewed too; we use this skewness Ir as a measure of the time irreversibility and we demonstrate that it increases sharply with the Stokes number St for small St; this increase slows down at St≃1 . Furthermore, we obtain the PDFs of t+ and t-, the times over which p has, respectively, positive or negative signs, i.e., the particle gains or loses energy. We obtain from these PDFs a direct and natural quantification of the slow gain and fast loss of the energy of the particles, because these PDFs possess exponential tails from which we infer the characteristic loss and gain times tloss and tgain, respectively, and we obtain tlossprobability in the strain-dominated region than in the vortical one; in contrast, the slow gain in the energy of the particles is equally likely in vortical or strain-dominated regions of the flow.

To explore and describe spouses' experiences of losing couplehood with their dementia-afflicted partner living in institutional care. Despite the losses and experiences of discontinuity due to the cognitive decline caused by dementia, the feelings of belonging and reciprocity in close relationships are still crucial to many couples. However, these experiences of spouses with partners living in institutional care are not well documented and are thus the focus of this study. A constructivist grounded theory approach was used to capture the relational processes described by the spouses. Conversational interviews were conducted with n = 10 spouses of dementia-afflicted persons living in institutional care. Data were analysed using the constant comparative method. The spouses' experiences of losing couplehood were primarily connected to separation from the partner and the sense of being alone. They were also related to the loss of the shared past and future. However, these experiences did not seem to be constant; short glimpses of connectedness, reciprocity and interdependence contributed to a feeling of couplehood, although these were only momentary. The spouses' experiences of losing couplehood were dynamic and were related to the couple's entire life. The spouses wavered between senses of loss and belonging to couplehood, depending on the conditions characterising the moment. Healthcare personnel must recognise the severity of some spouses' experiences of losing couplehood and be aware of how these experiences can fluctuate and be situation dependent. © 2014 John Wiley & Sons Ltd.

2018-05-01

Neuroblastoma and protein losing enteropathy (PLE) are diagnoses commonly seen by oncologists and gastroenterologists, respectively. The concurrence of these 2 entities is rare, and not well explained. We describe the sixth case of PLE in a child with neuroblastoma, and the first for which genetic information is available. Tumor DNA had a mutation in the PTPN11 gene, which has been described in neuroblastoma, and in Noonan syndrome-a diagnosis in which neuroblastoma and PLE independently have been reported. Constitutional DNA was normal. Genetic studies in future patients will be needed to support the link between neuroblastoma and PLE.

2009-01-01

The aim of the present study was to identify the game-related statistics that discriminated basketball winning and losing teams in each of the three consecutive games played in a condensed tournament format. The data were obtained from the Spanish Basketball Federation and included game-related statistics from the Under-20 league (2005-2006 and 2006-2007 seasons). A total of 223 games were analyzed with the following game-related statistics: two and three-point field goal (made and missed), free-throws (made and missed), offensive and defensive rebounds, assists, steals, turnovers, blocks (made and received), fouls committed, ball possessions and offensive rating. Results showed that winning teams in this competition had better values in all game-related statistics, with the exception of three point field goals made, free-throws missed and turnovers (p ≥ 0.05). The main effect of game number was only identified in turnovers, with a statistical significant decrease between the second and third game. No interaction was found in the analysed variables. A discriminant analysis allowed identifying the two-point field goals made, the defensive rebounds and the assists as discriminators between winning and losing teams in all three games. Additionally to these, only the three-point field goals made contributed to discriminate teams in game three, suggesting a moderate effect of fatigue. Coaches may benefit from being aware of this variation in game determinant related statistics and, also, from using offensive and defensive strategies in the third game, allowing to explore or hide the three point field-goals performance. Key points Overall team performances along the three consecutive games were very similar, not confirming an accumulated fatigue effect. The results from the three-point field goals in the third game suggested that winning teams were able to shoot better from longer distances and this could be the result of exhibiting higher conditioning status and

Full Text Available Abstract Background Physicians are encouraged to counsel obese patients to lose weight, but studies measuring the quality of physicians' counseling are rare. We sought to describe the quality of physicians' obesity counseling and to determine associations between the quality of counseling and obese patients' motivation and intentions to lose weight, key predictors of behavior change. Methods We conducted post-visit surveys with obese patients to assess physician's use of 5As counseling techniques and the overall patient-centeredness of the physician.. Patients also reported on their motivation to lose weight and their intentions to eat healthier and exercise. One-way ANOVAs were used to describe mean differences in number of counseling practices across levels of self-rated intention and motivation. Logistic regression analyses were conducted to assess associations between number of 5As counseling practices used and patient intention and motivation. Results 137 patients of 23 physicians were included in the analysis. While 85% of the patients were counseled about obesity, physicians used only a mean of 5.3 (SD = 4.6 of 18 possible 5As counseling practices. Patients with higher levels of motivation and intentions reported receiving more 5As counseling techniques than those with lower levels. Each additional counseling practice was associated with higher odds of being motivated to lose weight (OR 1.31, CI 1.11-1.55, intending to eat better (OR 1.23, CI 1.06-1.44, and intending to exercise regularly (OR 1.14, CI 1.00-1.31. Patient centeredness of the physician was also positively associated with intentions to eat better (OR 2.96, CI 1.03-8.47 and exercise (OR 26.07, CI 3.70-83.93. Conclusions Quality of physician counseling (as measured using the 5As counseling framework and patient-centeredness scales was associated with motivation to lose weight and intentions to change behavior. Future studies should determine whether higher quality obesity

2015-04-01

Full Text Available Since Aikhenvald 2004, evidentiality has been severed from epistemic modality. We studied the evidential and epistemic modal aspects of the Estonian evidential -vat experimentally and on the basis of a corpus study. We designed two experiments to separate the two categories. Four-, six-, and nine-year-old children were first asked to identify the source of the information provided with the morpheme. Then they performed a forced choice task guided by grammar: affirmative indicative, negative, and evidential sentences. Four-year-olds did not understand the evidential and modal -vat. Six year-olds showed an increased understanding of the evidential meaning but not the modal meaning or use. Nine-year-olds demonstrated full understanding of the evidential and an increased understanding of the epistemic modal aspect of the evidential. Estonian children thus develop the correct understanding of the morpheme -vat as an epistemic modal only after learning its evidential meaning.

Marginal Zone Lymphoma Complicated by Protein Losing Enteropathy

Directory of Open Access Journals (Sweden)

Nadine Stanek

2016-01-01

Full Text Available Protein losing enteropathy (PLE refers to excessive intestinal protein loss, resulting in hypoalbuminemia. Underlying pathologies include conditions leading to either reduced intestinal barrier or lymphatic congestion. We describe the case of a patient with long-lasting diffuse abdominal problems and PLE. Repetitive endoscopies were normal with only minimal lymphangiectasia in biopsies. Further evaluations revealed an indolent marginal zone lymphoma with minor bone marrow infiltration. Monotherapy with rituximab decreased bone marrow infiltration of the lymphoma but did not relieve PLE. Additional treatments with steroids, octreotide, a diet devoid of long-chain fatty-acids, and parenteral nutrition did not prevent further clinical deterioration with marked weight loss (23 kg, further reduction in albumin concentrations (nadir 8 g/L, and a pronounced drop in performance status. Finally, immunochemotherapy with rituximab and bendamustine resulted in hematological remission and remarkable clinical improvement. 18 months after therapy the patient remains free of gastrointestinal complaints and has regained his body weight with normal albumin levels. We demonstrate a case of PLE secondary to indolent marginal zone lymphoma. No intestinal pathologies were detected, contrasting a severe and almost lethal clinical course. Immunochemotherapy relieved lymphoma and PLE, suggesting that a high suspicion of lymphoma is warranted in otherwise unexplained cases of PLE.

To assess the risk of losing remission, low disease activity (LDA) or radiographic progression in the case of (1) discontinuing or (2) tapering doses of biological disease-modifying antirheumatic drugs (bDMARDs) compared with continuation of the initial treatment regimen in rheumatoid arthritis (RA) patients with remission or LDA. A systematic literature analysis was carried out through May 2017 on the PubMed, Embase, Cochrane and international congress databases, selecting controlled trials comparing bDMARDs discontinuation/tapering versus continuation in RA patients with remission or LDA. The meta-analysis assessed the risk ratio (RR) and 95% CI of losing remission or LDA and the risk of radiographic progression after (1) discontinuing and (2) tapering doses of bDMARDs versus continuing the initial treatment. The meta-analysis comparing bDMARDs discontinuation versus continuation performed on nine trials showed an increased risk of losing remission (RR (95% CI)=1.97(1.43 to 2.73), P<0.0001) or LDA (RR (95% CI)=2.24(1.52 to 3.30), P<0.0001) and an increased risk of radiographic progression (RR (95% CI)=1.09(1.02 to 1.17), P=0.01) in case of bDMARD discontinuation. The meta-analysis comparing bDMARDs tapering versus continuation performed on 11 trials showed an increased risk of losing remission (RR (95% CI)=1.23(1.06 to 1.42), P=0.006) but no increased risk of losing LDA (RR (95% CI)=1.02 (0.85 to 1.23), P=0.81) nor any increased risk of radiographic progression (RR (95% CI)=1.09(0.94 to 1.26), P=0.26) in case of bDMARD tapering. Discontinuation of bDMARDs leads to an increased risk of losing remission or LDA and radiographic progression, while tapering doses of bDMARDs does not increase the risk of relapse (LDA) or radiographic progression, even though there is an increased risk of losing remission. © Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2018.

Urosepsis in infants with vesicoureteral reflux masquerading as the salt-losing type of congenital adrenal hyperplasia

International Nuclear Information System (INIS)

Vaid, Y.N.; Lebowitz, R.L.

1989-01-01

Three male infants with vomiting, dehydration, hyponatremia, hyperkalemia and metabolic acidosis were found to have vesicoureteral reflux (VUR) and urinary tract infection. Two were initially thought to have the salt-losing form of congenital adrenal hyperplasia. Although prompt diagnosis of this potentially fatal condition is critical, its mimicry by urosepsis in infants with VUR is actually more common. Infection probably causes unresponsiveness of the distal renal tubules to aldoterone. (orig.)

Kirjanduslikest kontaktidest läbi raudse eesriide / Literary contacts through the iron curtain

Marin Laak

2016-09-01

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

The Effect of Suspended Sediment Transport and Deposition on Streambed Clogging Under Losing and Gaining Flow Conditions

Sediment transport and deposition in streams can affect streambed hydraulic characteristics due to clogging, reduce water fluxes through the hyporheic zone, and thus expected to affect biogeochemical processes. Processes affecting deposition of suspended particles were systematically studied under various overlying velocities but without taking into account the interactions with groundwater. This is despite the fact that the interaction with groundwater were shown to play an important role in deposition patterns of fine sediments in field studies. The objective of this study was to evaluate the effect of losing and gaining fluxes on suspended sediment depositional patterns and on hyporheic exchange fluxes. Experiments were conducted in a laboratory flume system (640 cm long and 30 cm wide) that has a capacity to enforce losing or gaining flow conditions. The flume was packed with homogenous sand, while suspended sediment deposition was evaluated by adding kaolinite particles to the water and following the deposition rate by particle disappearance from the bulk water. Consecutive additions of kaolinite were done, while hyporheic exchange fluxes were evaluated by conducting NaCl tracer experiments between each kaolinite additions. Furthermore, dye injections were used to visualize the flow patterns in the streambed using time-lapse photography through the transparent sidewalls of the flume. Hyporheic exchange and particle tracking simulations were done to assess the results of particle deposition and feedbacks between hyporheic flow, particle transport, and streambed clogging. Experimental results showed that the deposition of clay decreases with increasing amount of clay concentration in the sediment. Hyporheic exchange flux decreases linearly with increasing amount of clay added to the system and the region of active hyporheic exchange was confined to the upper part of the sediment.

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

The ability to keep track of time is perceived as crucial in most human societies. However, to lose track of time may also serve an important social role, associated with recreational purpose. To this end a number of social technologies are employed, some of which may relate to a manipulation of time perception through a modulation of body representation. Here, we investigated an influence of real-time or delayed videos of own-body representations on time perception in an experimental setup with virtual mirrors. Seventy participants were asked to either stay in the installation until they thought that a defined time (90 s) had passed, or they were encouraged to stay in the installation as long as they wanted and after exiting were asked to estimate the duration of their stay. Results show that a modulation of body representation by time-delayed representations of the mirror-video displays influenced time perception. Furthermore, these time-delayed conditions were associated with a greater sense of arousal and intoxication. We suggest that feeding in references to the immediate past into working memory could be the underlying mental mechanism mediating the observed modulation of time perception. We argue that such an influence on time perception would probably not only be achieved visually, but might also work with acoustic references to the immediate past (e.g., with music).

We present an extensive numerical study of the time irreversibility of the dynamics of heavy inertial particles in three-dimensional, statistically homogeneous, and isotropic turbulent flows. We show that the probability density function (PDF) of the increment, W(τ), of a particle's energy over a time scale τ is non-Gaussian, and skewed toward negative values. This implies that, on average, particles gain energy over a period of time that is longer than the duration over which they lose energy. We call this slow gain and fast loss. We find that the third moment of W(τ) scales as τ^{3} for small values of τ. We show that the PDF of power-input p is negatively skewed too; we use this skewness Ir as a measure of the time irreversibility and we demonstrate that it increases sharply with the Stokes number St for small St; this increase slows down at St≃1. Furthermore, we obtain the PDFs of t^{+} and t^{-}, the times over which p has, respectively, positive or negative signs, i.e., the particle gains or loses energy. We obtain from these PDFs a direct and natural quantification of the slow gain and fast loss of the energy of the particles, because these PDFs possess exponential tails from which we infer the characteristic loss and gain times t_{loss} and t_{gain}, respectively, and we obtain t_{loss}

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

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

Transplanted boys' love conventions and anti-shota polemics in a German manga: Fahr Sindram's Losing Neverland

Directory of Open Access Journals (Sweden)

Paul M. Malone

2013-03-01

Full Text Available Although manga arrived somewhat later in Germany than elsewhere in the West, the local publishers rapidly capitalized on its appeal to female readers and began fostering local manga artists in Germany. These are mainly young women producing shōjo manga, and increasingly integrating popular boys' love elements into their work. An unusual example of such work is Fahr Sindram's Losing Neverland, the story of an adolescent in Victorian London whose widowed father prostitutes him to middle-class men. Suggestive, though not visually explicit, such a story would likely run afoul of German and European Union laws against child pornography, were it not for the fact that Sindram continually reminds the reader that Neverland is in fact intended to raise awareness of child abuse and protest the dissemination of Japanese child pornography in Germany. Sindram thus openly advertises her work as a polemic, intended to mobilize the censorship of works seemingly much like her own; as a result, Losing Neverland has not only been socially accepted but even praised, earning an honorable citation from Germany's federal Council for Sustainable Development. Sindram's work thus accepts and capitalizes upon the globalizing aesthetic influence of manga, while at the same time adopting a defensive, quasi-protectionist stance against the spread of certain overtly foreign sexual attitudes associated with manga—and is visibly rewarded for doing so.

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

Understanding ionizing fluxes of stellar populations is crucial for various astrophysical problems including the epoch of reionization. Massive short-lived Wolf-Rayet stars are generally considered as the main ionizing sources. We examine the role of less massive stars that lose their envelope through interaction with a companion. We use the evolutionary code MESA and the radiative transfer code CMFGEN to investigate stripped stars as a function of metallicity (Z). We show that typical progen...

The use of low-calorie sweeteners is associated with self-reported prior intent to lose weight in a representative sample of US adults.

Drewnowski, A; Rehm, C D

2016-03-07

Low-calorie sweeteners (LCSs) are said to be a risk factor for obesity and diabetes. Reverse causality may be an alternative explanation. Data on LCS use, from a single 24-h dietary recall, for a representative sample of 22 231 adults were obtained from 5 cycles of the National Health and Nutrition Examination Survey (1999-2008 NHANES). Retrospective data on intent to lose or maintain weight during the prior 12-months and 10-year weight history were obtained from the weight history questionnaire. Objectively measured heights and weights were obtained from the examination. Primary analyses evaluated the association between intent to lose/maintain weight and use of LCSs and specific LCS product types using survey-weighted generalized linear models. We further evaluated whether body mass index (BMI) may mediate the association between weight loss intent and use of LCSs. The association between 10-year weight history and current LCS use was evaluated using restricted cubic splines. In cross-sectional analyses, LCS use was associated with a higher prevalence of obesity and diabetes. Adults who tried to lose weight during the previous 12 months were more likely to consume LCS beverages (prevalence ratio=1.64, 95% confidence interval (CI) 1.54-1.75), tabletop LCS (prevalence ratio=1.68, 95% CI 1.47-1.91) and LCS foods (prevalence ratio=1.93, 95% CI 1.60-2.33) as compared with those who did not. In mediation analyses, BMI only partially mediated the association between weight control history and the use of LCS beverages, tabletop LCS, but not LCS foods. Current LCS use was further associated with a history of prior weight change (for example, weight loss and gain). LCS use was associated with self-reported intent to lose weight during the previous 12 months. This association was only partially mediated by differences in BMI. Any inference of causality between attempts at weight control and LCS use is tempered by the cross-sectional nature of these data and retrospective

Application of Integral Pumping Tests to estimate the influence of losing streams on groundwater quality

Urban streams receive effluents of wastewater treatment plants and untreated wastewater during combined sewer overflow events. In the case of losing streams substances, which originate from wastewater, can reach the groundwater and deteriorate its quality. The estimation of mass flow rates Mex from losing streams to the groundwater is important to support groundwater management strategies, but is a challenging task. Variable inflow of wastewater with time-dependent concentrations of wastewater constituents causes a variable water composition in urban streams. Heterogeneities in the structure of the streambed and the connected aquifer lead, in combination with this variable water composition, to heterogeneous concentration patterns of wastewater constituents in the vicinity of urban streams. Groundwater investigation methods based on conventional point sampling may yield unreliable results under these conditions. Integral Pumping Tests (IPT) can overcome the problem of heterogeneous concentrations in an aquifer by increasing the sampled volume. Long-time pumping (several days) and simultaneous sampling yields reliable average concentrations Cav and mass flow rates Mcp for virtual control planes perpendicular to the natural flow direction. We applied the IPT method in order to estimate Mex of a stream section in Leipzig (Germany). The investigated stream is strongly influenced by combined sewer overflow events. Four pumping wells were installed up- and downstream of the stream section and operated for a period of five days. The study was focused on four inorganic (potassium, chloride, nitrate and sulfate) and two organic (caffeine and technical-nonylphenol) wastewater constituents with different transport properties. The obtained concentration-time series were used in combination with a numerical flow model to estimate Mcp of the respective wells. The difference of the Mcp's between up- and downstream wells yields Mex of wastewater constituents that increase

Saksa kirjandus Noor-Eesti ajal. Young Estonia and German Literature

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.

The aim of the present study was to identify the game-related statistics which discriminate between winning and losing teams in under-16 years old male basketball games. The sample gathered all 122 games in the 2004 and 2005 Under-16 European Championships. The game-related statistics analysed were the free-throws (both successful and unsuccessful), 2- and 3-points field-goals (both successful and unsuccessful) offensive and defensive rebounds, blocks, assists, fouls, turnovers and steals. The winning teams exhibited lower ball possessions per game and better offensive and defensive efficacy coefficients than the losing teams. Results from discriminant analysis were statistically significant and allowed to emphasize several structure coefficients (SC). In close games (final score differences below 9 points), the discriminant variables were the turnovers (SC = -0.47) and the assists (SC = 0.33). In balanced games (final score differences between 10 and 29 points), the variables that discriminated between the groups were the successful 2-point field-goals (SC = -0.34) and defensive rebounds (SC = -0. 36); and in unbalanced games (final score differences above 30 points) the variables that best discriminated both groups were the successful 2-point field-goals (SC = 0.37). These results allowed understanding that these players' specific characteristics result in a different game-related statistical profile and helped to point out the importance of the perceptive and decision making process in practice and in competition. Key points The players' game-related statistical profile varied according to game type, game outcome and in formative categories in basketball. The results of this work help to point out the different player's performance described in U-16 men's basketball teams compared with senior and professional men's basketball teams. The results obtained enhance the importance of the perceptive and decision making process in practice and in competition. PMID

Is Estonian oil shale beneficial in the future?

International Nuclear Information System (INIS)

Reinsalu, Enno

1998-01-01

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

Background Creatine supplementation can improve performance during high intensity exercise in humans and improve muscle strength in certain myopathies. In this present study, we investigated the direct effects of acute creatine incubation on isolated mouse fast-twitch EDL muscles, and examined how these effects change with fatigue. Methods and Results The extensor digitorum longus muscle from mice aged 12–14 weeks was isolated and stimulated with field electrodes to measure force characteristics in 3 different states: (i) before fatigue; (ii) immediately after a fatigue protocol; and (iii) after recovery. These served as the control measurements for the muscle. The muscle was then incubated in a creatine solution and washed. The measurement of force characteristics in the 3 different states was then repeated. In un-fatigued muscle, creatine incubation increased the maximal tetanic force. In fatigued muscle, creatine treatment increased the force produced at all frequencies of stimulation. Incubation also increased the rate of twitch relaxation and twitch contraction in fatigued muscle. During repetitive fatiguing stimulation, creatine-treated muscles took 55.1±9.5% longer than control muscles to lose half of their original force. Measurement of weight changes showed that creatine incubation increased EDL muscle mass by 7%. Conclusion Acute creatine application improves force production in isolated fast-twitch EDL muscle, and these improvements are particularly apparent when the muscle is fatigued. One likely mechanism for this improvement is an increase in Ca2+ sensitivity of contractile proteins as a result of ionic strength decreases following creatine incubation. PMID:21850234

Methods. The rs3740199, rs1871054, rs1278279, and rs1044122 SNPs in ADAM12 gene were genotyped in 438 subjects (303 women from population-based cohort, aged 32 to 57 (mean 45.4. The rKOA features were evaluated in the tibiofemoral joint (TFJ and patellofemoral joint. Results. The early rKOA was found in 51.4% of investigated subjects (72% women and 12.3% of participants (63% women had advanced stage of diseases. The A allele of synonymous SNP rs1044122 was associated with early rKOA in TFJ, predominantly with the presence of osteophytes in females (OR 1.57; 95% CI 1.08–2.29, . The C allele of intron polymorphism rs1871054 carried risk for advanced rKOA, mostly to osteophyte formation in TFJ in males (OR 3.03; 95% CI 1.11–7.53, . Also the CCAA haplotype of ADAM12 was associated with osteophytosis, again mostly in TFJ in males (. For rs3740199 and rs1278279, no statistically significant associations were observed. Conclusion.  ADAM12 gene variants are related to rKOA risk during the early and late stages of diseases. The genetic risk seems to be predominantly associated with the appearance of osteophytes—a marker of bone remodelling and neochondrogenesis.

Functional limitations are associated with decreased physical activity and increased body mass index. The purpose of this study was to assess the prevalence of functional limitations among adults who reported receiving health professional advice to exercise more or lose weight, and to assess involvement of health professionals, including physical therapists, in weight loss efforts with these individuals. A cross-sectional analysis of U.S. adults from the 2011 to 2014 National Health and Nutrition Examination Survey (n = 5,480). Participant demographics, health history, and functional limitations were assessed via self-report and examination. Frequency distributions were calculated using SAS® analytical software, accounting for the complex survey design. Population estimates were calculated using the American Community Survey. 31.0% of individuals (n = 1,696), representing a population estimate of 35 million adults, advised to exercise more or lose weight by a health professional reported one or more functional limitation. Of the 31%, 57.6% attempted weight loss, and 40.1% used exercise for weight loss. Few sought health professional assistance. Physical therapists were not mentioned. Few individuals with functional limitations advised to lose weight or increase exercise seek health professional assistance for weight loss. Physical therapists have an opportunity to assist those with functional limitations with exercise prescription.

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

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

Full Text Available In response to increasing concerns with the legitimacy and efficiency of public spending, performance management as a part of world-wide public sector reform, called New Public Management (NPM has taken place. This is also the case of educational sector. In Estonian education system, legislation formally enables to design an integrated performance management system. But there is few research done to investigate how these policies and regulations ought to be put into force in order to gain the benefits considering the schools' and pupils' better performance. This study investigates how different stakeholders are involved into the performance management in Estonian general schools. The study is based on empirical survey data gathered from 303 schools providing secondary education in Estonia. The research findings have three main implications. Firstly, the paper contributes to the scarce knowledge about implementation of performance management issues in public schools. Our analysis revealed that compilation of school development plans in Estonian schools is rather a formal obligation. Therefore we propose that the analysis and discussion of the school development plans is needed to organize on regional level, involving all main stakeholders of a school. Secondly, we suggest that in the circumstances of a decentralised education system, like in Estonia, it is needed to implement, central practical performance assessment principles and guidance for the schools. Thirdly, it is highly necessary to improve schools’ cooperation with different stakeholder groups. Also the framework involving different stakeholder groups in the decentralized schools management system should be built up.

Technetium-99m dextran: a promising new protein-losing enteropathy imaging agent

International Nuclear Information System (INIS)

Bhatnagar, A.; Singh, A.K.; Lahoti, D.; Singh, T.; Khanna, C.M.

1996-01-01

The purpose of this study was to evaluate technetium-99m dextran ( 99m Tc-Dx; molecular weight 81000) as a prospective protein-losing enteropathy (PLE) imaging agent. Twenty-two patients iwth diseases commonly associated with PLE and 12 healthy control subjects underwent intravenous 99m Tc-Dx scintigraphy. All of the 22 test patients showed significant radiotracer accumulation in the intestines within 3-4 h post injection. The focal, regional or generalised nature of the enteropathy and involvement of the large or small intestine could be identified in most cases. Four of the 12 apparently healthy subjects also showed minimal accumulation in the abdominal area occurring late in the study period. This could have been physiological, related to food habits or due to unsuspected intestinal worms. We attribute the high sensitivity of 99m Tc-Dx to its relatively fast blood (background) clearance. The radiotracer may have several other advantages over 99m Tc-labelled human serum albumin in imaging PLE. (orig.)

Winning the Battle but Losing the War? Narrative and Counter-Narratives Strategy

Christian Leuprecht

2010-11-01

Full Text Available Since 9/11, intelligence and security services have become particularly concerned about radical ideologies and have looked for ways on how to counter them. One of the strategies has been to develop a counter-narrative. Some authors, including those of this article, are concerned that, in the marketplace of ideas, the West is losing market-share.[1] Communication failures with the Muslim world were cited in a report by a U.S. Department of Defence Advisory Committee as early as 2004.[2] The puzzle this article explores is why, having recognized the problem early on, the data suggest that further ground has since been lost. We posit the problem as having to shift the discourse from one focusing on a single counter-narrative to one of tailoring communications to target specific audiences. The article traces methodological and empirical shortcomings that are at the root of the problem and builds on these findings to develop a model to strategize about counter-narratives.

Protein losing enteropathy (PLE) is a gastrointestinal disorder that is associated with excessive loss of plasma protein into the gut resulting from abnormal mucosal permeability. The disease is usually caused by inflammation. The loss of protein in PLE is a nonselective process affecting albumin, globulin and transferrin. Abdominal scintigraphy with human serum albumin marked by Tc99m seems to be an easy and sensitive method for diagnosing PLE. An 4-year-old girl was presented to an outside Pediatric Department due to hypoproteinemia and recurrent pneumonia which had caused several prior hospitalizations. The laboratory tests revealed hypoproteinemia, hypoalbuminemia, low level of IgG, sideropenia, and a decreased level of T lymphocytes. The loss of protein into the gut was confirmed by fecal clearance of alfa-1 antitrypsin. Only nonspecific inflammation was detected by biopsy of the small intestine. These clinical and laboratory findings, quickly decreasing IgG and albumin levels in spite of i.v. supplementation and the lack of proteinuria permitted PLE diagnosis. The abdominal scintigraphy was planned to assess and localise protein losing through GIT and for strategy of possible surgical treatment. Abdominal dynamic scintigraphy was performed immediately after the injection of 300 MBq Tc99m human albumin. 90 images were taken within 180 minutes. Delayed abdominal images were obtained 6 and 24 hours after the tracer injection. Anterior abdominal scintigraphy showed pathological activity of Tc99m-albumin in small bowel in the upper left segment of the abdomen in the 40th minute after injection. Extensive accumulation of albumin was seen in the 160th minute. Delayed images, after 3 and 6 hours, revealed translocation of the tracer into the lower right abdominal segment. The further passage and tracer concentration was detected in ascendant and transverse colon. Based on the laboratory tests and scintigraphic images the girl was suspected to have segmental

Corrected direct force balance method for atomic force microscopy lateral force calibration

Asay, David B.; Hsiao, Erik; Kim, Seong H.

2009-01-01

This paper reports corrections and improvements of the previously reported direct force balance method (DFBM) developed for lateral calibration of atomic force microscopy. The DFBM method employs the lateral force signal obtained during a force-distance measurement on a sloped surface and relates this signal to the applied load and the slope of the surface to determine the lateral calibration factor. In the original publication [Rev. Sci. Instrum. 77, 043903 (2006)], the tip-substrate contact was assumed to be pinned at the point of contact, i.e., no slip along the slope. In control experiments, the tip was found to slide along the slope during force-distance curve measurement. This paper presents the correct force balance for lateral force calibration.

Noor-Eesti tähendust otsides: vanu ja uusi mõtteid. In Quest of the Meaning of Young Estonia: Old and New Reflections

Directory of Open Access Journals (Sweden)

Jüri Kivimäe

2012-04-01

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

Investigation of Calibrating Force Transducer Using Sinusoidal Force

International Nuclear Information System (INIS)

Zhang Li; Wang Yu; Zhang Lizhe

2010-01-01

Sinusoidal force calibration method was studied several years before at Physikalisch-Technische Bundesanstalt (PTB). A similar dynamic force calibration system is developed at Changcheng Institute of Metrology and Measurement (CIMM). It uses electro-dynamic shakers to generate dynamic force in the range from 1 N to 20 kN, and heterodyne laser interferometers are used for acceleration measurement. The force transducer to be calibrated is mounted on the shaker, and a mass block is screwed on the top of force transducer, the sinusoidal forces realized by accelerated load masses are traceable to acceleration and mass according to the force definition. The methods of determining Spatial-dependent acceleration on mass block and measuring the end mass of force transducer in dynamic force calibration are discussed in this paper.

Greenhouse gases and their impact on the radiation balance

In Estonian conditions, winter is believed to be the most sensitive season to climate change. The generation and movement of the determining climate air masses depend on the location of the polar front and on cyclo genetic activity over the Northen Atlantic. Specific effects include regional forcing by the water vapor, clouds and aerosols. In summer and fall, the climate forming air can have a different origin and can be more stable. Still, it is poorly understood how the local effects of atmospheric circulation depend on the global energy distribution pattern and its changes

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

Disentangling the Roles of Atmospheric and Oceanic Forcing on the Last Deglaciation of the Greenland Ice Sheet

Science.gov (United States)

Keisling, B. A.; Deconto, R. M.

2017-12-01

Today the Greenland Ice Sheet loses mass via both oceanic and atmospheric processes. However, the relative importance of these mass balance components is debated, especially their potential impact on ongoing and future mass imbalance. Discerning the impact of oceanic versus atmospheric forcing during past periods of mass loss provides potential insight into the future behavior of the ice sheet. Here we present an ensemble of Greenland Ice Sheet simulations of the last deglaciation, designed to assess separately the roles of the ocean and the atmosphere in driving mass loss over the last twenty thousand years. We use twenty-eight different ocean forcing scenarios along with a cutting-edge reconstruction of time-evolving atmospheric conditions based on climate model output and δ15N-based temperature reconstructions to generate a range of ice-sheet responses during the deglaciation. We then compare the simulated timing of ice-retreat in individual catchments with estimates based on both 10Be (exposure) and 14C (minimum-limiting) dates. These experiments allow us to identify the ocean forcing scenario that best match the data on a local-to-regional (i.e., 100-1000 km) scales, providing an assessment of the relative importance of ocean and atmospheric forcing components around the periphery of Greenland. We use these simulations to quantify the importance of the three major mass balance terms (calving, oceanic melting, and surface melting) and assess the uncertainty of the relative influence of these factors during the most recent periods of major ice loss. Our results show that mass balance components around different sectors of the ice sheet respond differently to forcing, with oceanic components driving the majority of retreat in south and east Greenland and atmospheric forcing dominating in west and north Greenland In addition, we target three areas at high spatial resolution ( 1 km) around Greenland currently undergoing substantial change (Jakobshavn, Petermann

To characterize the medical history, disease progression, and treatment of current-era patients with the rare diseases Fontan-associated protein-losing enteropathy (PLE) and plastic bronchitis. A novel survey that queried demographics, medical details, and treatment information was piloted and placed online via a Facebook portal, allowing social media to power the study. Participation regardless of PLE or plastic bronchitis diagnosis was allowed. Case control analyses compared patients with PLE and plastic bronchitis with uncomplicated control patients receiving the Fontan procedure. The survey was completed by 671 subjects, including 76 with PLE, 46 with plastic bronchitis, and 7 with both. Median PLE diagnosis was 2.5 years post-Fontan. Hospitalization for PLE occurred in 71% with 41% hospitalized ≥ 3 times. Therapy varied significantly. Patients with PLE more commonly had hypoplastic left ventricle (62% vs 44% control; OR 2.81, 95% CI 1.43-5.53), chylothorax (66% vs 41%; OR 2.96, CI 1.65-5.31), and cardiothoracic surgery in addition to staged palliation (17% vs 5%; OR 4.27, CI 1.63-11.20). Median plastic bronchitis diagnosis was 2 years post-Fontan. Hospitalization for plastic bronchitis occurred in 91% with 61% hospitalized ≥ 3 times. Therapy was very diverse. Patients with plastic bronchitis more commonly had chylothorax at any surgery (72% vs 51%; OR 2.47, CI 1.20-5.08) and seasonal allergies (52% vs 36%; OR 1.98, CI 1.01-3.89). Patient-specific factors are associated with diagnoses of PLE or plastic bronchitis. Treatment strategies are diverse without clear patterns. These results provide a foundation upon which to design future therapeutic studies and identify a clear need for forming consensus approaches to treatment. Copyright © 2015 Elsevier Inc.

Noonan's syndrome is a rare congenital disorder that may be associated with abnormalities in the lymphatic drainage. In this case of a 21-year-old man CT after bipedal lymphangiography confirmed the diagnosis of intestinal lymphangiectasy causing protein-losing enteropathy in Noonan's syndrome by showing contrast-enhanced abnormal lymphatic vessels in the mesentery and the intestinal wall. Because of the benefit of diet in case of intestinal involvement, we recommend a thorough documentation of the lymphatic drainage with lymphangiography followed by CT, if clinical signs of lymphatic dysplasia, such as pleural effusions, lymphedema, or hypoproteinemia are present.

Osterstock, Jason B; Mansell, Joanne L; Roussel, Allen J

2005-11-01

Prototheca spp are achlorophyllic saprophytic algae found in wastewater, sewage, agricultural waste, and possibly elsewhere in the environment. Infections with these organisms have been reported in cattle, humans, and dogs; affected cattle commonly develop mastitis. A 5-year-old Brahman-cross bull was evaluated because of a history of diarrhea and weight loss. The history and physical examination and clinicopathologic findings were similar to those associated with granulomatous enteritis caused by Mycobacterium avium subsp paratuberculosis (Johne's disease), which is the most common protein-losing enteropathy of cattle. However, diagnostic tests for paratuberculosis yielded negative results. Biopsy specimens from the ileum, jejunum, and ileocecal lymph node were collected for histologic examination and preparation of tissue impression smears; Prototheca-like organisms were identified. Because of the poor prognosis associated with this infection and the lack of safe and economical therapeutic agents for cattle, the owner decided to euthanatize the bull. Infection with Prototheca organisms was confirmed postmortem. As this case illustrates, protothecosis may be a cause of granulomatous enteritis in cattle.

Computation of Estonian CORS data using Bernese 5.2 and Gipsy 6.4 softwares

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

This case report describes a toddler who developed a protein-losing enteropathy (PLE) 4 years after orthotopic heart transplantation (OHT). He was born with a hypoplastic left heart syndrome for which he underwent a successful Norwood procedure, a Hemi-Fontan palliation, and a Fontan palliation at 18 months of age. Fifteen months following the Fontan operation, he developed a PLE and Fontan failure requiring OHT. Four years after OHT, he developed a severe tricuspid regurgitation and a PLE. His PLE improved after tricuspid valve replacement. It is now 2 years since his tricuspid valve replacement and he remains clinically free of ascites and peripheral edema with a normal serum albumin level. His prosthetic tricuspid valve is functioning normally. © 2011 Wiley Periodicals, Inc.

Mutations in Plasmalemma Vesicle Associated Protein Result in Sieving Protein-Losing Enteropathy Characterized by Hypoproteinemia, Hypoalbuminemia, and HypertriglyceridemiaSummary

Full Text Available Background & Aims: Severe intestinal diseases observed in very young children are often the result of monogenic defects. We used whole-exome sequencing (WES to examine genetics in a patient with a distinct severe form of protein-losing enteropathy (PLE characterized by hypoproteinemia, hypoalbuminemia, and hypertriglyceridemia. Methods: WES was performed at the Centre for Applied Genomics, Hospital for Sick Children, Toronto, Canada, and exome library preparation was performed with the Ion Torrent AmpliSeq RDY Exome Kit. Functional studies were based on the identified mutation. Results: Using WES we identified a homozygous nonsense mutation (1072C>T; p.Arg358* in the PLVAP (plasmalemma vesicle-associated protein gene in an infant from consanguineous parents who died at 5 months of age of severe PLE. Functional studies determined that the mutated PLVAP mRNA and protein were not expressed in the patient biopsy tissues, presumably secondary to nonsense-mediated mRNA decay. Pathological analysis showed that the loss of PLVAP resulted in disruption of endothelial fenestrated diaphragms. Conclusions: The PLVAP p.Arg358* mutation resulted in the loss of PLVAP expression with subsequent deletion of the diaphragms of endothelial fenestrae, which led to plasma protein extravasation, PLE, and ultimately death.

Gibson, M.; Larden, D.W.; Angelides, S.; Roman, M.R.

2003-01-01

Full text: Protein losing enteropathy (PLE) is an uncommon complication following right heart bypass operations (Fontan procedure-FP) caused by chronically raised systemic venous pressure with perhaps concomitant immunological or inflammatory factors. Medical, transcatheter, and surgical therapies aimed at reducing systemic venous pressure are often unsuccessful. Conversely, where intestinal protein loss is circumscribed to a relatively small region, surgical resection has been reported as beneficial. However, confirmation of localised disease is difficult. Nuclear scintigraphy can potentially determine extent of disease. A 14-year-old girl with a background history of tricuspid atresia, right ventricular hypoplasia and ventricular- and atrial-septal defects developed PLE post-FP, resulting in cardiac failure, chronic pleural effusions and worsening ascites. Her condition gradually deteriorated and became refractory to therapy. A 99Tcm-Dextran study was performed for further evaluation. 99Tcm-Dextran 77 000 (260 MBq) was produced aseptically from a previously prepared sterile 'cold kit'. Radiochemical purity was found to be > 95%. Anterior and posterior planar scans of the lower chest, abdomen and pelvis were acquired continuously over the initial 2 h post-intravenous injection of radiotracer using a dual-head gamma-camera. There was focal abnormal accumulation of tracer in the left flank demonstrated, consistent with localised disease, which was confirmed on subsequent small bowel biopsies. The patient is awaiting a limited small bowel resection. Thus, 99Tcm-Dextran scintigraphy was useful in determining extent of disease and further management.

Full Text Available Abstract Background Little research has given consideration to how people's weight control behaviors may moderate the relationships between nutrition and body mass index (BMI in large cross-sectional studies. The objective of the current study is to determine how attempts to lose weight confound the relationships between nutrition behaviors and BMI among a population of predominately overweight adolescents. Methods Data were drawn from the baseline measurements of the Pacific OPIC (Obesity Prevention In Communities. Participants included approximately 3500 high school students in New Zealand. Students in the sample primarily identified as a Pacific Island ethnicity (57% and the mean age for participants was 14.8 years. Participants completed a questionnaire about nutrition and physical activity patterns and were weighed and measured for height. Results In our sample, 57% of students were overweight/obese, with the highest prevalence among Pacific Island students (71%. Approximately 50% of students were currently trying to lose weight, and this was more common among females, Pacific Island students and overweight/obese students. Examination of the nutritional correlates of BMI in the total population found inverse relationships between BMI and consumption of high-fat/high-sugar foods and positive relationships between BMI and eating 5 or more fruits and vegetables a day (all significant after controlling for age, sex, and ethnicity. For example, students who drank the most soft drinks or ate fruit and vegetables infrequently had the lowest mean BMI. Students' attempts to change their weight significantly moderated the relationships between most nutritional behaviors and BMI. In most cases, among students not trying to change their weight, expected relationships were observed; among students trying to lose weight, unexpected or no relationships were observed.

Child-raising, Childbirth and Abortion In Extremis: Women’s Stories of Caring for and Losing Children during the Violence of 1965–1966 in Indonesia

Annie Pohlman

2013-01-01

Full Text Available In this paper I examine women survivors’ stories about childbirth and child-raising during the period of mass violence following Indonesia’s 1965 coup, as well as some accounts of abortion during detention. The focus of my research is not on children’s experiences per se but rather on women survivors’ accounts about what happened to their children. I discuss various aspects of these experiences, including: being pregnant and giving birth; caring for children in and outside detention; the harm and abuse of children; losing children; and forced abortions. These stories reveal much about how women cared for and lost children as well as about what happened to children during the violence of 1965. I argue that examining these experiences must therefore also be central to understanding how women and their children survived and coped with the mass violence of 1965–1966. I also argue that these stories of caring for children, as well as of how children were harmed or lost, were fundamental parts of many women’s testimonies.

2010-03-01

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

Protein-losing enteropathy (PLE) is a rare complication of Fontan palliation associated with significant morbidity and mortality. It is characterized by the loss of serum proteins into the intestinal lumen, and its pathophysiology likely involves enteral inflammation. Budesonide, an oral steroid, is an attractive treatment option because of its potent enteral activity and minimal systemic side effects. A single-center, retrospective review of Fontan-palliated PLE patients treated with oral budesonide for 6 months or longer was performed. The patient characteristics reviewed were demographics, anatomic diagnosis, budesonide treatment (dose and duration), other medications and therapeutic interventions, hospitalizations, serum albumin levels, medical complications, and patient status at the time of follow-up assessment. The study enrolled 10 patients representing 228 patient-months of on-therapy follow-up evaluation. Serum albumin levels increased after initiation of budesonide for 90% of the patients, and clinical evidence of fluid overload improved for 60% of them. Symptomatic improvement was reported in 80% of the cases. During the treatment period, 50% of the patients met the primary end point of death or cardiac transplantation. In this series of PLE patients, oral budesonide therapy was associated with significant symptomatic improvement and sustained increases in serum albumin. However, budesonide therapy may not alter the long-term outcome for patients with advanced PLE.

2011-05-01

Nearly all physics instructors recognize the instructional value of force diagrams, and this journal has published several collections of exercises to improve student skill in this area.1-4 Yet some instructors worry that too few students perceive the conceptual and problem-solving utility of force diagrams,4-6 and over recent years a rich variety of approaches has been proposed to add value to force diagrams. Suggestions include strategies for identifying candidate forces,6,7 emphasizing the distinction between "contact" and "noncontact" forces,5,8 and the use of computer-based tutorials.9,10 Instructors have suggested a variety of conventions for constructing force diagrams, including approaches to arrow placement and orientation2,11-13 and proposed notations for locating forces or marking action-reaction force pairs.8,11,14,15

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.

[Genome loses all 5-methylcytosine a life span. How is this connected with accumulation of mutations during aging?].

Science.gov (United States)

Mazin, A L

1993-01-01

The 5-methylcytosine (5mC) content in liver DNA has been determined for rats of different age. The rate of the 5mC loss from DNA is maximal in pre- and neonatal rats, 1.28% of reduction of the 5mC content per day, then it decreases to 0.33% and becomes minimal and constant in adult rats, 0.028% per day. During pregnancy and the first 15 days of postnatal development rat genome loses 49% of all 5mC. Within the next 45 days 15% of 5mC disappears, and during maximal rat life span, about four years, 39% of the genomic 5mC may be lost. Thus, it has been found for the first time that the animal genome loses practically all 5mC residues during the life span. Analysis of the literature data shows that for embryos the rate of the 5mC loss from DNA proves to be higher than that for adult animals by 96 times for mice, 69-for rats and 28-for cows. The rate of embryonal DNA hypomethylation may be inversely proportional to the pregnancy duration of species. In adult animals the rate inversely correlates with their maximal life span and accounts for the 5mC loss from DNA of a mouse by 0.028%, of a rat by 0.024%, of a hamster by 0.007%, of a cow by 0.004% and of a human being by 0.0005% per day. During the entire ontogenesis, the genome of a mouse loses 93% of all 5mC residues, that of a rat-101% and of a cow-88%. The age-dependent loss of 5mC from DNA is also typical for cell lines aging in vitro. It is constant, as a rule, and correlates with the number of cell population doublings (PD). The removal of all 5mC from DNA corresponds to 70-130 PD for human, 40-60 PD-for hamster and 6 PD- for mouse cells. In immortal lines the level of DNA methylation is stable or grows with age. A possible mechanism of an age-related 5mC loss from DNA is discussed. DNA hypomethylation may result from 5mC deamination directly at the moment of replicative DNA methylation and subsequent reparation of the G.T mispairs which leads to accumulation of the 5mC-->T+C substitutions in the genome with each

Forced phase-locked response of a nonlinear system with time delay after Hopf bifurcation

International Nuclear Information System (INIS)

Ji, J.C.; Hansen, Colin H.

2005-01-01

The trivial equilibrium of a nonlinear autonomous system with time delay may become unstable via a Hopf bifurcation of multiplicity two, as the time delay reaches a critical value. This loss of stability of the equilibrium is associated with two coincident pairs of complex conjugate eigenvalues crossing the imaginary axis. The resultant dynamic behaviour of the corresponding nonlinear non-autonomous system in the neighbourhood of the Hopf bifurcation is investigated based on the reduction of the infinite-dimensional problem to a four-dimensional centre manifold. As a result of the interaction between the Hopf bifurcating periodic solutions and the external periodic excitation, a primary resonance can occur in the forced response of the system when the forcing frequency is close to the Hopf bifurcating periodic frequency. The method of multiple scales is used to obtain four first-order ordinary differential equations that determine the amplitudes and phases of the phase-locked periodic solutions. The first-order approximations of the periodic solutions are found to be in excellent agreement with those obtained by direct numerical integration of the delay-differential equation. It is also found that the steady state solutions of the nonlinear non-autonomous system may lose their stability via either a pitchfork or Hopf bifurcation. It is shown that the primary resonance response may exhibit symmetric and asymmetric phase-locked periodic motions, quasi-periodic motions, chaotic motions, and coexistence of two stable motions

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

International Nuclear Information System (INIS)

Hammer, Hele

1998-01-01

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

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

Force and Directional Force Modulation Effects on Accuracy and Variability in Low-Level Pinch Force Tracking.

Science.gov (United States)

Park, Sangsoo; Spirduso, Waneen; Eakin, Tim; Abraham, Lawrence

2018-01-01

The authors investigated how varying the required low-level forces and the direction of force change affect accuracy and variability of force production in a cyclic isometric pinch force tracking task. Eighteen healthy right-handed adult volunteers performed the tracking task over 3 different force ranges. Root mean square error and coefficient of variation were higher at lower force levels and during minimum reversals compared with maximum reversals. Overall, the thumb showed greater root mean square error and coefficient of variation scores than did the index finger during maximum reversals, but not during minimum reversals. The observed impaired performance during minimum reversals might originate from history-dependent mechanisms of force production and highly coupled 2-digit performance.

Unrealistic weight loss expectations (WLEs) and greater body dissatisfaction may be associated with the poor long-term outcomes of dietary and lifestyle weight loss treatments. We evaluated the association between body size, WLEs and body dissatisfaction in young women attempting to lose weight. Forty-four young healthy women [age range 18-35 years, body mass index (BMI) range 23-40 kg/m2] were recruited. Women were classified as obese (BMI ≥ 30.0 kg/m2) and non-obese (BMI social (career, family acceptance, peer acceptance, mass media, social pressure) factors. Individual WLEs were compared with recommended clinical targets (5%, 10% and 20%) for weight loss. Body dissatisfaction was lower in non-obese subjects and was directly associated with BMI (P media, whereas they perceived that family and friends were supportive of a lesser degree of weight loss. We observed a mismatch between clinical and personal expectations, and social pressure and interpersonal relationships appear to have a prominent role with respect to influencing the association. © 2013 The Authors Journal of Human Nutrition and Dietetics © 2013 The British Dietetic Association Ltd.

Direct measurements of intermolecular forces by chemical force microscopy

Science.gov (United States)

Vezenov, Dmitri Vitalievich

1999-12-01

Detailed description of intermolecular forces is key to understanding a wide range of phenomena from molecular recognition to materials failure. The unique features of atomic force microscopy (AFM) to make point contact force measurements with ultra high sensitivity and to generate spatial maps of surface topography and forces have been extended to include measurements between well-defined organic molecular groups. Chemical modification of AFM probes with self-assembled monolayers (SAMs) was used to make them sensitive to specific molecular interactions. This novel chemical force microscopy (CFM) technique was used to probe forces between different molecular groups in a range of environments (vacuum, organic liquids and aqueous solutions); measure surface energetics on a nanometer scale; determine pK values of the surface acid and base groups; measure forces to stretch and unbind a short synthetic DNA duplex and map the spatial distribution of specific functional groups and their ionization state. Studies of adhesion forces demonstrated the important contribution of hydrogen bonding to interactions between simple organic functionalities. The chemical identity of the tip and substrate surfaces as well as the medium had a dramatic effect on adhesion between model monolayers. A direct correlation between surface free energy and adhesion forces was established. The adhesion between epoxy polymer and model mixed SAMs varied with the amount of hydrogen bonding component in the monolayers. A consistent interpretation of CFM measurements in polar solvents was provided by contact mechanics models and intermolecular force components theory. Forces between tips and surfaces functionalized with SAMs terminating in acid or base groups depended on their ionization state. A novel method of force titration was introduced for highly local characterization of the pK's of surface functional groups. The pH-dependent changes in friction forces were exploited to map spatially the

Integrated Hydrogeological Investigation on the Vulnerability of a Pumping Station at a Losing Stream

River restoration usually includes alteration of the river channel morphology. Thereby the interaction between river and groundwater can be modified. For the design of a river restoration project - especially in the vicinity of a groundwater pumping well for drinking water production - this impact must be predicted. But a good prediction requires a proper understanding of the existing situation. Numerical models help to improve the strategy of a successful river restoration project. The main objective of this study was to investigate the vulnerability of a pumping station located at losing river in northeast Switzerland. Besides the effect that river restoration could create, a particular attention was placed on the effect of a beaver dam in a side channel close to the pumping station. Analysis of field measurements coupled with numerical modeling of the pumping station area improved the understanding of the interactions in the river corridor between the river, side channels and the alluvial aquifer.

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

Triathletes, who constantly engage in intensely stressful sport, were recently found to exhibit greater pain tolerance and more efficient pain inhibition capabilities than nonathletes. However, pain inhibition correlated negatively with retrospective reports of mental stress during training and competition. The aim of the current study was to test pain inhibition capabilities of triathletes under acute, controlled psychological stress manipulation. Participants were 25 triathletes and ironman triathletes who underwent the measurement of pain threshold, pain intolerance, tonic suprathreshold pain, and conditioned pain modulation before and during exposure to the Montreal Imaging Stress Task (MIST). Perceived ratings of stress and anxiety, autonomic variables, and salivary cortisol levels were obtained as indices of stress. The MIST induced a significant stress reaction manifested in the subjective and objective indices. Overall, a significant reduction in pain threshold and in conditioned pain modulation efficacy was observed after the MIST, which reached the baseline levels observed previously in nonathletes. Paradoxically, the magnitude of this stress-induced hyperalgesia (SIH) correlated negatively with the magnitude of the stress response; low-stress responders exhibited greater SIH than high-stress responders. The results suggest that under acute psychological stress, triathletes not only react with SIH and a reduction in pain modulation but also lose their advantageous pain modulation over nonathletes. The stronger the stress response recorded, the weaker the SIH. It appears that triathletes are not resilient to stress, responding with an increase in the sensitivity to pain as well as a decrease in pain inhibition. The possible effects of athletes' baseline pain profile and stress reactivity on SIH are discussed.

This report describes two patients with sporadic lymphangioleiomyomatosis complicated by protein-losing enteropathy (PLE). Imaging studies indicated retroperitoneal lymphangioleiomyomas and abnormalities of the adjacent digestive tract. Endoscopic mucosal biopsy revealed colonic lymphangiectasia in one patient; whereas the site in the other patient was intestinal. Treatment with sirolimus led to the complete resolution of PLE within several months; additionally, marked shrinkage was observed in the lymphangioleiomyomas of both cases. These findings suggest that colonic or intestinal lymphatic congestion due to neighboring lymphangioleiomyomas was the mechanism for the development of PLE. At the time of writing this report, the beneficial effect of sirolimus has lasted for more than 3 years.

Dispersion Forces

Buhmann, Stefan Yoshi

2012-01-01

In this book, a modern unified theory of dispersion forces on atoms and bodies is presented which covers a broad range of advanced aspects and scenarios. Macroscopic quantum electrodynamics is shown to provide a powerful framework for dispersion forces which allows for discussing general properties like their non-additivity and the relation between microscopic and macroscopic interactions. It is demonstrated how the general results can be used to obtain dispersion forces on atoms in the presence of bodies of various shapes and materials. Starting with a brief recapitulation of volume I, this volume II deals especially with bodies of irregular shapes, universal scaling laws, dynamical forces on excited atoms, enhanced forces in cavity quantum electrodynamics, non-equilibrium forces in thermal environments and quantum friction. The book gives both the specialist and those new to the field a thorough overview over recent results in the field. It provides a toolbox for studying dispersion forces in various contex...

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

Noonan's syndrome is a rare congenital disorder that may be associated with abnormalities in the lymphatic drainage. In this case of a 21-year-old man CT after bipedal lymphangiography confirmed the diagnosis of intestinal lymphangiectasy causing protein-losing enteropathy in Noonan's syndrome by showing contrast-enhanced abnormal lymphatic vessels in the mesentery and the intestinal wall. Because of the benefit of diet in case of intestinal involvement, we recommend a thorough documentation of the lymphatic drainage with lymphangiography followed by CT, if clinical signs of lymphatic dysplasia, such as pleural effusions, lymphedema, or hypoproteinemia are present.

Hubble Space Telescope Imaging of the Mass-losing Supergiant VY Canis Majoris

1998-04-01

The highly luminous M supergiant VY CMa is a massive star that appears to be in its final death throes, losing mass at high rate en route to exploding as a supernova. Subarcsecond-resolution optical images of VY CMa, obtained with the Faint Object Camera (FOC) aboard the Hubble Space Telescope, vividly demonstrate that mass loss from VY CMa is highly anisotropic. In the FOC images, the optical ``star'' VY CMa constitutes the bright, well-resolved core of an elongated reflection nebula. The imaged nebula is ~3" (~4500 AU) in extent and is clumpy and highly asymmetric. The images indicate that the bright core, which lies near one edge of the nebula, is pure scattered starlight. We conclude that at optical wavelengths VY CMa is obscured from view along our line of sight by its own dusty envelope. The presence of the extended reflection nebula then suggests that this envelope is highly flattened and/or that the star is surrounded by a massive circumstellar disk. Such axisymmetric circumstellar density structure should have profound effects on post-red supergiant mass loss from VY CMa and, ultimately, on the shaping of the remnant of the supernova that will terminate its post-main-sequence evolution.

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

Science.gov (United States)

2014-01-01

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

Cellular traction force is one of the important factors for understanding cell behaviors, such as spreading, migration and differentiation. Cells are known to change their behavior according to the mechanical stiffness of the environment. However, the measurement of cell traction forces on a rigid environment has remained difficult. This paper reports a micro-electromechanical systems (MEMS) force plate that provides a cellular traction force measurement on a rigid substrate. Both the high force sensitivity and high stiffness of the substrate were obtained using piezoresistive sensing elements. The proposed force plate consists of a 70 µ m  ×  15 µ m  ×  5 µ m base as the substrate for cultivating a bovine aortic smooth muscle cell, and the supporting beams with piezoresistors on the sidewall and the surface were used to measure the forces in both the horizontal and vertical directions. The spring constant and force resolution of the fabricated force plate in the horizontal direction were 0.2 N m −1 and less than 0.05 µ N, respectively. The cell traction force was measured, and the traction force increased by approximately 1 µ N over 30 min. These results demonstrate that the proposed force plate is applicable as an effective traction force measurement. (paper)

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

Automated force controller for amplitude modulation atomic force microscopy

Atomic Force Microscopy (AFM) is widely used in physics, chemistry, and biology to analyze the topography of a sample at nanometer resolution. Controlling precisely the force applied by the AFM tip to the sample is a prerequisite for faithful and reproducible imaging. In amplitude modulation (oscillating) mode AFM, the applied force depends on the free and the setpoint amplitudes of the cantilever oscillation. Therefore, for keeping the applied force constant, not only the setpoint amplitude but also the free amplitude must be kept constant. While the AFM user defines the setpoint amplitude, the free amplitude is typically subject to uncontrollable drift, and hence, unfortunately, the real applied force is permanently drifting during an experiment. This is particularly harmful in biological sciences where increased force destroys the soft biological matter. Here, we have developed a strategy and an electronic circuit that analyzes permanently the free amplitude of oscillation and readjusts the excitation to maintain the free amplitude constant. As a consequence, the real applied force is permanently and automatically controlled with picoNewton precision. With this circuit associated to a high-speed AFM, we illustrate the power of the development through imaging over long-duration and at various forces. The development is applicable for all AFMs and will widen the applicability of AFM to a larger range of samples and to a larger range of (non-specialist) users. Furthermore, from controlled force imaging experiments, the interaction strength between biomolecules can be analyzed.

Imaging stability in force-feedback high-speed atomic force microscopy

International Nuclear Information System (INIS)

Kim, Byung I.; Boehm, Ryan D.

2013-01-01

We studied the stability of force-feedback high-speed atomic force microscopy (HSAFM) by imaging soft, hard, and biological sample surfaces at various applied forces. The HSAFM images showed sudden topographic variations of streaky fringes with a negative applied force when collected on a soft hydrocarbon film grown on a grating sample, whereas they showed stable topographic features with positive applied forces. The instability of HSAFM images with the negative applied force was explained by the transition between contact and noncontact regimes in the force–distance curve. When the grating surface was cleaned, and thus hydrophilic by removing the hydrocarbon film, enhanced imaging stability was observed at both positive and negative applied forces. The higher adhesive interaction between the tip and the surface explains the improved imaging stability. The effects of imaging rate on the imaging stability were tested on an even softer adhesive Escherichia coli biofilm deposited onto the grating structure. The biofilm and planktonic cell structures in HSAFM images were reproducible within the force deviation less than ∼0.5 nN at the imaging rate up to 0.2 s per frame, suggesting that the force-feedback HSAFM was stable for various imaging speeds in imaging softer adhesive biological samples. - Highlights: ► We investigated the imaging stability of force-feedback HSAFM. ► Stable–unstable imaging transitions rely on applied force and sample hydrophilicity. ► The stable–unstable transitions are found to be independent of imaging rate

Losing jobs and lighting up: Employment experiences and smoking in the Great Recession.

Science.gov (United States)

Golden, Shelley D; Perreira, Krista M

2015-08-01

The Great Recession produced the highest rates of unemployment observed in decades, in part due to particularly high rates of people losing work involuntarily. The impact of these job losses on health is unknown, due to the length of time required for most disease development, concerns about reverse causation, and limited data that covers this time period. We examine associations between job loss, employment status and smoking, the leading preventable cause of death, among 13,571 individuals participating in the 2001-2011 waves of the U.S.-based Panel Study of Income Dynamics. Results indicate that recent involuntary job loss is associated with an average 1.1 percentage point increase in smoking probability. This risk is strongest when people have returned to work, and appears reversed when they leave the labor market altogether. Although some job loss is associated with changes in household income and psychological distress levels, we find no evidence that these changes explain smoking behavior modifications. Smoking prevention programs and policies targeted at displaced workers or the newly employed may alleviate some negative health effects produced by joblessness during the Great Recession.

Abdominal scintigraphy with intravenous injection of 99m Tc-labeled serum albumin was performed in 6 patients with protein-losing enteropathy (PLE) and 3 patients with nongastrointestinal tract disorders. In 3 out of 6 patients with PLE, abnormal radioactivity was observed in the ileum region 3 hours after injection, and thereafter clear colon image was obtained. In the remaining 3 patients, the colon was visualized 24 hours after injection. On the other hand, in all patients with nongastrointestinal tract disorders, no abnormal radioactivity was observed in the abdomen until 24 hours after injection. These results indicate that gastrointestinal protein loss could be demonstrated by scintigraphy with intravenously administered 99m Tc-labeled serum albumin. In one healthy subject, 99m Tc-labeled serum albumin was administered orally and abdominal scintigraphy was performed. Gastrointestinal tract image was only observed and no other image was demonstrated until 24 hours after oral administration. This result suggests that 99m Tc excreted into the gastrointestinal tract is not reabsorbed. Therefore, abdominal scintigraphy with 99m Tc-labeled serum albumin appears to be a simple and useful method for diagnosis of PLE. (author)

Single-molecule force spectroscopy is a powerful technique for addressing single molecules. Unseen structures and dynamics of molecules have been elucidated using force spectroscopy. Atomic force microscope (AFM)-based force spectroscopy studies have provided picoNewton force resolution, subnanometer spatial resolution, stiffness of substrates, elasticity of polymers, and thermodynamics and kinetics of single-molecular interactions. In addition, AFM has enabled mapping the distribution of individual molecules in situ, and the quantification of single molecules has been made possible without modification or labeling. In this review, we describe the basic principles, sample preparation, data analysis, and applications of AFM-based force spectroscopy and its future.

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

Protein-losing enteropathy (PLE), characterized by severe hypoalbuminemia and peripheral edema, is a rare manifestation of systemic lupus erythematosus. This present study aimed to identify the distinctive features of lupus-related PLE and evaluate the factors related to the treatment response. From March 1998 to March 2014, the clinical data of 14 patients with lupus PLE and seven patients with idiopathic PLE from a tertiary center were reviewed. PLE was defined as a demonstration of protein leakage from the gastrointestinal tract by either technetium 99m-labelled human albumin scanning or fecal α1-antitrypsin clearance. A positive steroid response was defined as a return of serum albumin to ≥ 3.0 g/dL within 4 weeks after initial steroid monotherapy, and remission as maintenance of serum albumin ≥ 3.0 g/dL for at least 3 months. A high serum total cholesterol level was defined as a level of ≥ 240 mg/dL. The mean age of the lupus-related PLE patients was 37.0 years, and the mean follow-up duration was 55.8 months. Significantly higher erythrocyte sedimentation rate and serum total cholesterol levels were found for lupus PLE than for idiopathic PLE. Among the 14 patients with lupus PLE, eight experienced a positive steroid response, and the serum total cholesterol level was significantly higher in the positive steroid response group. A positive steroid response was associated with an initial high serum total cholesterol level and achievement of remission within 6 months. In lupus-related PLE, a high serum total cholesterol level could be a predictive factor for the initial steroid response, indicating a good response to steroid therapy alone.

Three-nucleon forces

International Nuclear Information System (INIS)

Sauer, P.U.

2014-01-01

In this paper, the role of three-nucleon forces in ab initio calculations of nuclear systems is investigated. The difference between genuine and induced many-nucleon forces is emphasized. Induced forces arise in the process of solving the nuclear many-body problem as technical intermediaries toward calculationally converged results. Genuine forces make up the Hamiltonian. They represent the chosen underlying dynamics. The hierarchy of contributions arising from genuine two-, three- and many-nucleon forces is discussed. Signals for the need of the inclusion of genuine three-nucleon forces are studied in nuclear systems, technically best under control, especially in three-nucleon and four-nucleon systems. Genuine three-nucleon forces are important for details in the description of some observables. Their contributions to observables are small on the scale set by two-nucleon forces. (author)

2015 Tax-Competitiveness Report: Canada is Losing its Attractiveness

Directory of Open Access Journals (Sweden)

Philip Bazel

2016-11-01

Full Text Available It can be easy for Canadians who appreciate the qualities of their country to overestimate the power that it also has to lure investment in a world where so many other destinations are competing for capital. Canadians can take pride in our political stability and our highly educated workforce, and we do have good communication and transportation infrastructure, but a great number of other countries offer those things, too, at roughly the same level. Meanwhile, Canada suffers in the eyes of investors for being a relatively small market, distant from large export destinations, with a cold climate and geographic vastness that only raise the cost of doing business here. Canada has been able to overcome its disadvantages in recent years largely by being highly competitive on business taxes. Unfortunately, the tendency of Canadian provincial and federal governments lately to raise taxes on business has been rapidly erasing that slight advantage. Dangerously, Canada is beginning to lose its competitive edge. It is difficult enough in a world of slower global growth to attract investment, but some major economies with whom Canada directly competes for investment have recognized the need in this challenging environment to make themselves even more attractive to investors. It is true that some countries, such as Belgium, Chile, Brazil, Greece and India have, like Canada, enacted certain policies — primarily higher business taxes — that have increased their marginal effective tax rate (METR. Still, other important peer countries have been working to lower theirs; notably Denmark, Japan, France, Portugal, Switzerland and the U.K. As a result of their cuts, and because of changes to policies in Canada that have increased METRs here, Canada has sunk from having the 16th-highest burden on capital in the OECD (which was at least in the middle of the pack to having the 13th highest. We now have the sixth-highest rather than lowest METR in the G7. In a

Uncertainties in forces extracted from non-contact atomic force microscopy measurements by fitting of long-range background forces

Directory of Open Access Journals (Sweden)

Adam Sweetman

2014-04-01

Full Text Available In principle, non-contact atomic force microscopy (NC-AFM now readily allows for the measurement of forces with sub-nanonewton precision on the atomic scale. In practice, however, the extraction of the often desired ‘short-range’ force from the experimental observable (frequency shift is often far from trivial. In most cases there is a significant contribution to the total tip–sample force due to non-site-specific van der Waals and electrostatic forces. Typically, the contribution from these forces must be removed before the results of the experiment can be successfully interpreted, often by comparison to density functional theory calculations. In this paper we compare the ‘on-minus-off’ method for extracting site-specific forces to a commonly used extrapolation method modelling the long-range forces using a simple power law. By examining the behaviour of the fitting method in the case of two radically different interaction potentials we show that significant uncertainties in the final extracted forces may result from use of the extrapolation method.

People trying to lose weight dislike calorie counting apps and want motivational support to help them achieve their goals.

Two thirds of UK adults are overweight or obese and at increased risk of chronic conditions such as heart disease, diabetes and certain cancers. Basic public health support for weight loss comprises information about healthy eating and lifestyle, but internet and mobile applications (apps) create possibilities for providing long-term motivational support. To explore among people currently trying to lose weight, or maintaining weight loss, (i) problems, experiences and wishes in regards to weight management and weight loss support including e-health support; (ii) reactions to Functional Imagery Training (FIT) as a possible intervention. Six focus groups ( N  = 24 in total) were recruited from a public pool of people who had expressed an interest in helping with research. The topics considered were barriers to weight loss, desired support for weight loss and acceptability of FIT including the FIT app. The focus group discussions were transcribed and thematically analysed. All groups spontaneously raised the issue of waning motivation and expressed the desire for motivational app support for losing weight and increasing physical activity. They disliked calorie counting apps and those that required lots of user input. All groups wanted behavioural elements such as setting and reviewing goals to be included, with the ability to personalise the app by adding picture reminders and choosing times for goal reminders. Participants were positive about FIT and FIT support materials. There is a mismatch between the help provided via public health information campaigns and commercially available weight-loss self-help (lifestyle information, self-monitoring), and the help that individuals actually desire (motivational and autonomous e-support), posing an opportunity to develop more effective electronic, theory-driven, motivational, self-help interventions.

Hepatic dysfunctions are not infrequent in patients with hyperthyroidism. These disorders may be related to the effects of the excess thyroid hormone secretion, to the uses of antithyroid drugs, or to the presence of concomitant hepatic diseases. Our aim is to describe the clinical and biochemical features of liver dysfunction related to thyrotoxicosis. We report here a case of a 6-year-old girl who was admitted for jaundice and pruritus as a result of the development of hyperthyroidism due to Graves' disease. On physical examination at admission, she was found to have jaundice and hepatomegaly. Laboratory data show cholestasis and protein-losing enteropathy. Investigations exclude other causes of hepatic disorder. One month after the initiation of antithyroid drug, the patient became euthyroid with improvement in jaundice and pruritus and normalization of hepatic tests and alpha antitrypsine clearance. In conclusion, the diagnosis of hyperthyroidism may be delayed in patients in whom the primary manifestations were pruritus and jaundice. The physician should suspect thyrotoxicosis prior to hepatitis or skin manifestations.

We present Heisenberg's equation of motion for the radial variable of a free non-relativistic particle in D dimensions. The resulting radial force consists of three contributions: (i) the quantum fictitious force which is either attractive or repulsive depending on the number of dimensions, (ii......) a singular quantum force located at the origin, and (iii) the centrifugal force associated with non-vanishing angular momentum. Moreover, we use Heisenberg's uncertainty relation to introduce a lower bound for the kinetic energy of an ensemble of neutral particles. This bound is quadratic in the number...... of atoms and can be traced back to the repulsive quantum fictitious potential. All three forces arise for a free particle: "Force without force"....

Taste blindness to 6-n-propylthiouracil (PROP) associates with increased fat preference and intake. No studies have matched a diet to a woman's PROP phenotype to improve weight loss. This study investigated (1) whether PROP nontaster (NT) women would lose more weight following a low-carbohydrate (LC) diet than a low-fat (LF) diet, and (2) whether PROP supertaster (ST) women would lose more weight following a LF diet than a LC diet. One hundred seven women (BMI = 34.8 ± 0.5 kg/m 2 ), classified as PROP NTs (n = 47) and STs (n = 60), were randomized to a LC or LF diet within a 6-month lifestyle intervention. Assessments included 4-day dietary recalls and biobehavioral and psychosocial questionnaires. At 6 months, NTs lost more weight following the LC than the LF diet (-8.5 ± 0.5 kg vs. -6.6 ± 0.5 kg, P = 0.008); there was no difference between STs following either diet (-8.8 ± 0.4 vs. -8.9 ± 0.5, P = 0.35). Dietary self-reports were unrelated to weight loss, and prescription of a LC diet associated with greater self-efficacy. NT women lost more weight following the LC diet compared to the LF diet. Screening for PROP phenotype may help personalize diet therapy for NT women to optimize their short-term weight loss. © 2017 The Authors.

Investigating riparian groundwater flow close to a losing river using diurnal temperature oscillations at high vertical resolution

Directory of Open Access Journals (Sweden)

T. Vogt

2012-02-01

Full Text Available River-water infiltration is of high relevance for hyporheic and riparian groundwater ecology as well as for drinking water supply by river-bank filtration. Heat has become a popular natural tracer to estimate exchange rates between rivers and groundwater. However, quantifying flow patterns and velocities is impeded by spatial and temporal variations of exchange fluxes, insufficient sensors spacing during field investigations, or simplifying assumptions for analysis or modeling such as uniform flow. The objective of this study is to investigate lateral shallow groundwater flow upon river-water infiltration at the shoreline of the riverbed and in the adjacent riparian zone of the River Thur in northeast Switzerland. Here we have applied distributed temperature sensing (DTS along optical fibers wrapped around tubes to measure high-resolution vertical temperature profiles of the unsaturated zone and shallow riparian groundwater. Diurnal temperature oscillations were tracked in the subsurface and analyzed by means of dynamic harmonic regression to extract amplitudes and phase angles. Subsequent calculations of amplitude attenuation and time shift relative to the river signal show in detail vertical and temporal variations of heat transport in shallow riparian groundwater. In addition, we apply a numerical two-dimensional heat transport model for the unsaturated zone and shallow groundwater to obtain a better understanding of the observed heat transport processes in shallow riparian groundwater and to estimate the groundwater flow velocity. Our results show that the observed riparian groundwater temperature distribution cannot be described by uniform flow, but rather by horizontal groundwater flow velocities varying over depth. In addition, heat transfer of diurnal temperature oscillations from the losing river through shallow groundwater is influenced by thermal exchange with the unsaturated zone. Neglecting the influence of the unsaturated zone

Will OPEC lose from the Kyoto Protocol?

International Nuclear Information System (INIS)

Barnett, Jon; Dessai, Suraje; Webber, Michael

2004-01-01

A range of energy-economy models forecast losses to members of the Organisation of Petroleum Exporting Countries (OPEC) should the Kyoto Protocol come into force. These forecasts are a powerful influence in the United Nations Framework Convention on Climate Change negotiations. They are used by OPEC to advance the agenda on the impacts of response measures, covertly arguing for compensation for lost oil revenues arising from implementation of the Protocol. This paper discusses this issue, and explores the key assumptions of these models and their uncertainties. Assumptions about carbon leakage, future availability of oil reserves, substitution, innovation, and capital turnover are considered. The paper suggests that losses will not affect OPEC countries equally, and that these losses are not likely to be as substantial as the models forecast. A range of policy measures are proposed to lessen any impact the Protocol may have on OPEC

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

Recent research has shown that of the 72% of American Internet users who have looked for health information online, 22% have searched for help to lose or control weight. This demand for information has given rise to many online weight management communities, where users support one another throughout their weight loss process. Whether and how user engagement in online communities relates to weight change is not totally understood. We investigated the activity behavior and analyze the semantic content of the messages of active users in LoseIt (r/loseit), a weight management community of the online social network Reddit. We then explored whether these features are associated with weight loss in this online social network. A data collection tool was used to collect English posts, comments, and other public metadata of active users (ie, users with at least one post or comment) on LoseIt from August 2010 to November 2014. Analyses of frequency and intensity of user interaction in the community were performed together with a semantic analysis of the messages, done by a latent Dirichlet allocation method. The association between weight loss and online user activity patterns, the semantics of the messages, and real-world variables was found by a linear regression model using 30-day weight change as the dependent variable. We collected posts and comments of 107,886 unique users. Among these, 101,003 (93.62%) wrote at least one comment and 38,981 (36.13%) wrote at least one post. Median percentage of days online was 3.81 (IQR 9.51). The 10 most-discussed semantic topics on posts were related to healthy food, clothing, calorie counting, workouts, looks, habits, support, and unhealthy food. In the subset of 754 users who had gender, age, and 30-day weight change data available, women were predominant and 92.9% (701/754) lost weight.

Force reconstruction from tapping mode force microscopy experiments

Payam, Amir F; Martin-Jimenez, Daniel; Garcia, Ricardo

2015-01-01

Fast, accurate, and robust nanomechanical measurements are intensely studied in materials science, applied physics, and molecular biology. Amplitude modulation force microscopy (tapping mode) is the most established nanoscale characterization technique of surfaces for air and liquid environments. However, its quantitative capabilities lag behind its high spatial resolution and robustness. We develop a general method to transform the observables into quantitative force measurements. The force reconstruction algorithm has been deduced on the assumption that the observables (amplitude and phase shift) are slowly varying functions of the tip–surface separation. The accuracy and applicability of the method is validated by numerical simulations and experiments. The method is valid for liquid and air environments, small and large free amplitudes, compliant and rigid materials, and conservative and non-conservative forces. (paper)

Inferring Interaction Force from Visual Information without Using Physical Force Sensors.

Science.gov (United States)

Hwang, Wonjun; Lim, Soo-Chul

2017-10-26

In this paper, we present an interaction force estimation method that uses visual information rather than that of a force sensor. Specifically, we propose a novel deep learning-based method utilizing only sequential images for estimating the interaction force against a target object, where the shape of the object is changed by an external force. The force applied to the target can be estimated by means of the visual shape changes. However, the shape differences in the images are not very clear. To address this problem, we formulate a recurrent neural network-based deep model with fully-connected layers, which models complex temporal dynamics from the visual representations. Extensive evaluations show that the proposed learning models successfully estimate the interaction forces using only the corresponding sequential images, in particular in the case of three objects made of different materials, a sponge, a PET bottle, a human arm, and a tube. The forces predicted by the proposed method are very similar to those measured by force sensors.

RISKS OF LOSING CONTROLLABILITY WHILE LIBERALIZING THE ELECTRIC POWER INDUSTRY

Full Text Available The paper analyses controllability qua a reliability characteristic of the electric-power grid controlling system. The following notions are used: the object (environment susceptibility towards the control stimuli, the controlling system adequacy, environment of the secure functioning. The author points to the necessity of accounting for the limitations of technological and organizational character. While liberalizing the electric-power industry, the backbone control-principle “the industry functioning reliability” is being replaced with the principle of “profit-making” that requires complete restatement of the control philosophy.The conflict between commercial benefit gaining and the reliability assurance expenses leads to losing controllability in all the managerial links and to probable catastrophic consequences. The recapitulation of the Russian Federation power industry privatization substantiates concerns of the liberal ideas poor survivability in the ex-Soviet territories. The results of degradation of the secure-functioning environment demonstrate affinity of the mechanisms that triggered the Chernobyl NPP, Fukusima NPP, and Sayan-Shushenskya HPP disasters. Securing reliability of the strategic objects leaves the competence boundaries of the electricpower industry.The topical issue of Belorussian electric-power industry functioning and developing is the combination of technical re-equipment (developing the operational dispatch management and the control-system organizational modernizing in general with gradual and controllable transition to the market mechanisms of functioning. Herewith, preserving the state monopoly on regime provision for the operation of the electric-power system should not leave out the industry appeal for outside investment and is regulated by the optimal degree and intensity of the state participation in governing the electric-power supply industry.

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

To comprehensively characterize the immunologic characteristics of patients with protein-losing enteropathy (PLE) post-Fontan and compare them with patients without PLE post-Fontan. Patients with PLE post-Fontan and age-matched controls post-Fontan were prospectively studied with laboratory markers of immune function. Infectious history was obtained by interview and chart review. The groups' demographics, cardiac history, immune characteristics, and infection history were compared using appropriate 2-group statistics. A total of 16 patients enrolled (8 patients with PLE and 8 controls). All patients with PLE had lymphopenia compared with 25% of controls (P = .01). All patients with PLE had markedly depressed CD4 T cell counts (median 58 cells/μL) compared with controls (median 450 cells/μL, P = .0002); CD4% was also low in the PLE group (12.3%) and normal in control (36.9%, P = .004). Both groups had mildly depressed CD8 T cells and normal to slightly elevated natural killer and B-cell subsets. A majority of patients with PLE (62.5%) had negative titers to measles, mumps, and rubella vaccination, compared with no control Fontan with a negative titer (P = .03). Despite profoundly low CD4 counts, the frequency of infection was not different between groups with no reported opportunistic infections. Patients with Fontan-associated PLE have extensive quantitative immune abnormalities, particularly CD4 deficiency. These immune abnormalities are similar to those found in non-Fontan patients with PLE caused by intestinal lymphangiectasia. Copyright © 2015 Elsevier Inc. All rights reserved.

Digital force-feedback for protein unfolding experiments using atomic force microscopy

Since its invention in the 1990s single-molecule force spectroscopy has been increasingly applied to study protein (un-)folding, cell adhesion, and ligand-receptor interactions. In most force spectroscopy studies, the cantilever of an atomic force microscope (AFM) is separated from a surface at a constant velocity, thus applying an increasing force to folded bio-molecules or bio-molecular bonds. Recently, Fernandez and co-workers introduced the so-called force-clamp technique. Single proteins were subjected to a defined constant force allowing their life times and life time distributions to be directly measured. Up to now, the force-clamping was performed by analogue PID controllers, which require complex additional hardware and might make it difficult to combine the force-feedback with other modes such as constant velocity. These points may be limiting the applicability and versatility of this technique. Here we present a simple, fast, and all-digital (software-based) PID controller that yields response times of a few milliseconds in combination with a commercial AFM. We demonstrate the performance of our feedback loop by force-clamp unfolding of single Ig27 domains of titin and the membrane proteins bacteriorhodopsin (BR) and the sodium/proton antiporter NhaA.

Quantum anticentrifugal force

In a two-dimensional world, a free quantum particle of vanishing angular momentum experiences an attractive force. This force originates from a modification of the classical centrifugal force due to the wave nature of the particle. For positive energies the quantum anticentrifugal force manifests itself in a bunching of the nodes of the energy wave functions towards the origin. For negative energies this force is sufficient to create a bound state in a two-dimensional δ-function potential. In a counterintuitive way, the attractive force pushes the particle away from the location of the δ-function potential. As a consequence, the particle is localized in a band-shaped domain around the origin

Effects of Low-Permeability Layers in the Hyporheic Zone on Oxygen Consumption Under Losing and Gaining Groundwater Flow Conditions

Recent studies at the watershed scale have demonstrated the dominant role that river bedforms play in driving hyporheic exchange and constraining biogeochemical processes along river corridors. At the reach and bedform scales, modeling studies have shown that sediment heterogeneity significantly modifies hyporheic flow patterns within bedforms, resulting in spatially heterogeneous biogeochemical processes. In this work, we summarize a series of flume experiments to evaluate the effect that low-permeability layers, representative of structural heterogeneity, have on hyporheic exchange and oxygen consumption in sandy streambeds. In this case, we systematically changed the geometry of the heterogeneities, the surface channel flow driving the exchange, and groundwater fluxes (gaining/losing) modulating the exchange. The flume was packed with natural sediments, which were amended with compost to minimize carbon limitations. Structural heterogeneities were represented by continuous and discontinuous layers of clay material. Flow patterns were studied using dye imaging through the side walls. Oxygen distribution in the streambed was measured using planar optodes. The experimental observations revealed that the clay layer had a significant effect on flow patterns and oxygen distribution in the streambed under neutral and losing conditions. Under gaining conditions, the aerobic zone was limited to the upper sections of the bedform and thus was less influenced by the clay layers that were located at a depth of 1-3 cm below the water-sediment interface. We are currently analyzing the results with a numerical flow and transport model to quantify the reactions rates under the different flow conditions and spatial sediment structures. Our preliminary results enable us to show the importance of the coupling between flow conditions, local heterogeneity within the streambed and oxygen consumption along bed forms and are expected to improve our ability to model the effect of stream

The effect of force feedback delay on stiffness perception and grip force modulation during tool-mediated interaction with elastic force fields.

Leib, Raz; Karniel, Amir; Nisky, Ilana

2015-05-01

During interaction with objects, we form an internal representation of their mechanical properties. This representation is used for perception and for guiding actions, such as in precision grip, where grip force is modulated with the predicted load forces. In this study, we explored the relationship between grip force adjustment and perception of stiffness during interaction with linear elastic force fields. In a forced-choice paradigm, participants probed pairs of virtual force fields while grasping a force sensor that was attached to a haptic device. For each pair, they were asked which field had higher level of stiffness. In half of the pairs, the force feedback of one of the fields was delayed. Participants underestimated the stiffness of the delayed field relatively to the nondelayed, but their grip force characteristics were similar in both conditions. We analyzed the magnitude of the grip force and the lag between the grip force and the load force in the exploratory probing movements within each trial. Right before answering which force field had higher level of stiffness, both magnitude and lag were similar between delayed and nondelayed force fields. These results suggest that an accurate internal representation of environment stiffness and time delay was used for adjusting the grip force. However, this representation did not help in eliminating the bias in stiffness perception. We argue that during performance of a perceptual task that is based on proprioceptive feedback, separate neural mechanisms are responsible for perception and action-related computations in the brain.

Electrostatic force is an essential component of the total force acting between atoms and macromolecules. Therefore, accurate calculations of electrostatic forces are crucial for revealing the mechanisms of many biological processes. We developed a DelPhiForce web server to calculate and visualize the electrostatic forces at molecular level. DelPhiForce web server enables modeling of electrostatic forces on individual atoms, residues, domains and molecules, and generates an output that can be visualized by VMD software. Here we demonstrate the usage of the server for various biological problems including protein-cofactor, domain-domain, protein-protein, protein-DNA and protein-RNA interactions.

2005-01-01

Measurements, using atomic force microscopy, of the force and force derivative on a charged insulating micron sized sphere as a function of gap between the sphere and a conductive plane have revealed attractive forces at finite gaps that are larger than predicted by either van der Waals or conventional electrostatic forces. We suggest that these observations may be due to an electrostatic force that we have identified theoretically and call the proximity force. This proximity force is due to the discrete charges on the surface of the sphere in close proximity to the plane

Control and minimization of tip-sample interaction forces are imperative tasks to maximize the performance of atomic force microscopy. In particular, when imaging soft biological matter in liquids, the cantilever dragging force prevents identification of the tip-sample mechanical contact, resulting in deleterious interaction with the specimen. In this work we present an improved jumping mode procedure that allows detecting the tip-sample contact with high accuracy, thus minimizing the scanning forces ({approx}100 pN) during the approach cycles. To illustrate this method we report images of human adenovirus and T7 bacteriophage particles which are prone to uncontrolled modifications when using conventional jumping mode. -- Highlights: Black-Right-Pointing-Pointer Improvement in atomic force microscopy in buffer solution. Black-Right-Pointing-Pointer Peak force detection. Black-Right-Pointing-Pointer Subtracting the cantilever dragging force. Black-Right-Pointing-Pointer Forces in the 100 pN range.

Integrin-transmitted cellular forces are critical for platelet adhesion, activation, aggregation and contraction during hemostasis and thrombosis. Measuring and mapping single platelet forces are desired in both research and clinical applications. Conventional force-to-strain based cell traction force microscopies have low resolution which is not ideal for cellular force mapping in small platelets. To enable platelet force mapping with submicron resolution, we developed a force-activatable biosensor named integrative tension sensor (ITS) which directly converts molecular tensions to fluorescent signals, therefore enabling cellular force mapping directly by fluorescence imaging. With ITS, we mapped cellular forces in single platelets at 0.4µm resolution. We found that platelet force distribution has strong polarization which is sensitive to treatment with the anti-platelet drug tirofiban, suggesting that the ITS force map can report anti-platelet drug efficacy. The ITS also calibrated integrin molecular tensions in platelets and revealed two distinct tension levels: 12-54 piconewton (nominal values) tensions generated during platelet adhesion and tensions above 54 piconewton generated during platelet contraction. Overall, the ITS is a powerful biosensor for the study of platelet mechanobiology, and holds great potential in antithrombotic drug development and assessing platelet activity in health and disease.

This study examined concurrent validity of countermovement vertical jump (CMJ) reactive strength index modified and force-time characteristics recorded using a one dimensional portable and laboratory force plate system. Twenty-eight men performed bilateral CMJs on two portable force plates placed on top of two in-ground force plates, both recording vertical ground reaction force at 1000 Hz. Time to take-off, jump height, reactive strength index modified, braking and propulsion impulse, mean net force, and duration were calculated from the vertical force from both force plate systems. Results from both systems were highly correlated (r≥.99). There were small (dbraking impulse, braking mean net force, propulsion impulse, and propulsion mean net force (psystem (95% CL: .9% to 2.5%), indicating very good agreement across all of the dependent variables. The largest limits of agreement belonged to jump height (2.1%), time to take-off (3.4%), and reactive strength index modified (3.8%). The portable force plate system provides a valid method of obtaining reactive strength measures, and several underpinning force-time variables, from unloaded CMJ and practitioners can use both force plates interchangeably.

Fowles (1983), citing evidence from separate studies, suggests that both incentive and response cost paradigms increase heart rate and should be subsumed under Gray's (1975) 'appetitive motivational system'. Shock avoidance and loss of reward (response cost) contingencies, while aversive, appear to evoke this motivational system; consequently both should elicit heart rate increases independent of anxiety. The present investigation compared magnitude of heart rate changes observed under conditions of winning and losing money. Results showed: no differences between incentive and response cost conditions; no effect of state anxiety on heart rate in these conditions, despite an elevation of state anxiety on the task day relative to a subsequent relaxation day assessment; and some evidence for the presence under both such appetitive conditions of cardiovascular hyperresponsivity among offspring of hypertensive parents. The results suggest a need for systematic parametric studies of experimental conditions.

A 47-yr-old man with hepatitis B virus associated liver cirrhosis was admitted to our hospital with diarrhea and generalized edema and diagnosed as protein-losing enteropathy due to intestinal lymphangiectasia by intestinal biopsy and 99mTc albumin scan. During hospitalization, he received subcutaneous octreotide therapy. After 2 weeks of octreotide therapy, follow-up albumin scan showed no albumin leakage, and the serum albumin level was sustained. We speculate that liver cirrhosis can be a cause of intestinal lymphangiectasia and administration of octreotide should be considered for patients with intestinal lymphangiectasia whose clinical and biochemical abnormalities do not respond to a low-fat diet.

Forces in general relativity

International Nuclear Information System (INIS)

Ridgely, Charles T

2010-01-01

Many textbooks dealing with general relativity do not demonstrate the derivation of forces in enough detail. The analyses presented herein demonstrate straightforward methods for computing forces by way of general relativity. Covariant divergence of the stress-energy-momentum tensor is used to derive a general expression of the force experienced by an observer in general coordinates. The general force is then applied to the local co-moving coordinate system of a uniformly accelerating observer, leading to an expression of the inertial force experienced by the observer. Next, applying the general force in Schwarzschild coordinates is shown to lead to familiar expressions of the gravitational force. As a more complex demonstration, the general force is applied to an observer in Boyer-Lindquist coordinates near a rotating, Kerr black hole. It is then shown that when the angular momentum of the black hole goes to zero, the force on the observer reduces to the force on an observer held stationary in Schwarzschild coordinates. As a final consideration, the force on an observer moving in rotating coordinates is derived. Expressing the force in terms of Christoffel symbols in rotating coordinates leads to familiar expressions of the centrifugal and Coriolis forces on the observer. It is envisioned that the techniques presented herein will be most useful to graduate level students, as well as those undergraduate students having experience with general relativity and tensor analysis.

This study determined how sociocultural messages to change one's body are perceived by adolescents from different cultural groups. In total, 4904 adolescents, including Australian, Chilean, Chinese, Indo-Fijian, Indigenous Fijian, Greek, Malaysian, Chinese Malaysian, Tongans in New Zealand, and Tongans in Tonga, were surveyed about messages from family, peers, and the media to lose weight, gain weight, and increase muscles. Groups were best differentiated by family pressure to gain weight. Girls were more likely to receive the messages from multiple sociocultural sources whereas boys were more likely to receive the messages from the family. Some participants in a cultural group indicated higher, and others lower, levels of these sociocultural messages. These findings highlight the differences in sociocultural messages across cultural groups, but also that adolescents receive contrasting messages within a cultural group. These results demonstrate the difficulty in representing a particular message as being characteristic of each cultural group. Copyright © 2014 Elsevier Ltd. All rights reserved.

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

Jantson, Signe

2006-12-01

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

Full Text Available Gaucher disease (OMIM #230800 is caused by β-glucosidase deficiency and primarily involves the mononuclear phagocyte system (also called Reticuloendothelial System or Macrophage System. The disease is classified into three main phenotypes based on the presence or absence of neurological manifestations: non-neuronopathic (type 1, acute neuronopathic (type 2 and chronic neuronopathic (type 3. Typical manifestations include hepatosplenomegaly, skeletal deformities, hematological abnormalities, interstitial lung fibrosis and neurodegeneration in neuronopathic cases. Mesenteric lymphadenopathy with resultant protein losing enteropathy (PLE has only been rarely described. Mesenteric lymphadenopathy may lead to intestinal lymphatic obstruction and secondary lymphangiectasia resulting in chronic diarrhea, abdominal pain and weight loss. Fecal protein loss with secondary hypoalbuminemia can be significant. We report a male with Chronic Neuronopathic Gaucher disease (GD (homozygous for c.1448T>C (NM_000157.3 GBA mutation who at 16 years of age developed intractable abdominal pain, diarrhea and weight loss. This was caused by PLE secondary to intestinal lymphangiectasia caused by calcified mesenteric lymphadenopathy despite prior long term enzyme replacement therapy (ERT and/or substrate reduction therapy (SRT. His older similarly affected sister who had been receiving treatment with ERT and/or SRT remains stable on these treatments with no evidence of mesenteric lymphadenopathy. Medical management with total parenteral nutrition, daily medium chain triglyceride-oil (MCT supplementation, low dose oral budesonide, continued oral SRT and an increased dose of parenteral ERT has stabilized his condition with resolution of the gastrointestinal symptoms and appropriate weight gain.

Protein-losing enteropathy (PLE) is characterised by gastrointestinal protein leakage due to loss of mucosal integrity or lymphatic abnormalities. PLE can manifest as congenital diarrhoea and should be differentiated from other congenital diarrhoeal disorders. Primary PLEs are genetically heterogeneous and the underlying genetic defects are currently emerging. We report an infant with fatal PLE for whom we aimed to uncover the underlying pathogenic mutation. We performed whole exome sequencing (WES) for the index patient. Variants were classified based on the American College of Medical Genetics and Genomics guidelines. WES results and our detailed clinical description of the patient were compared with the literature. We discovered a novel homozygous stop mutation (c.988C>T, p.Q330*) in the Plasmalemma Vesicle-Associated Protein ( PLVAP ) gene in a newborn with fatal PLE, facial dysmorphism, and renal, ocular and cardiac anomalies. The Q330* mutation is predicted to result in complete loss of PLVAP protein expression leading to deletion of the diaphragms of endothelial fenestrae, resulting in plasma protein extravasation and PLE. Recently, another single homozygous stop mutation in PLVAP causing lethal PLE in an infant was reported. Our findings validate PLVAP mutations as a cause of syndromic PLE. Prenatal anomalies, severe PLE and syndromic features may guide the diagnosis of this rare disease. © Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2018.

Certain amino acids are decreased in humans with inflammatory bowel disease (IBD) and supplementation with the same amino acids has shown beneficial effects in animal models of IBD. Currently, the amino acid status of dogs with protein-losing enteropathy (PLE) is unknown. To determine if serum amino acid concentrations are abnormal in dogs with PLE and correlated with clinical and laboratory variables and outcome. Thirty client-owned dogs diagnosed with PLE and 12 apparently healthy dogs seen at Bristol Veterinary School. Retrospective study using stored residual serum from fasted dogs with PLE, collected at the time of diagnostic investigation and from apparently healthy dogs. Serum was analyzed for 30 amino acids using an automated high-performance liquid chromatography amino acid analyzer. Serum tryptophan concentrations were significantly decreased in dogs with PLE (median, 22 nmol/mL; range, 1-80 nmol/mL) compared with apparently healthy control dogs (median, 77.5 nmol/mL; range, 42-135 nmol/mL, P PLE and apparently healthy. Serum tryptophan concentrations were also significantly correlated with serum albumin concentrations in dogs with PLE (P = .001, R 2 = 0.506). Decreased serum tryptophan concentration might play a role in the pathogenesis of canine PLE or be a consequence of the disease. © 2018 The Authors.

Perez Diaz, M

2008-01-01

Full text: A key to store and/or transmit digital medical images obtained from modern technologies is the size in bytes they occupy difficulty. One way to solve the above is the implementation of compression algorithms (codecs) with or without losses. Particularly the latter do allow significant reductions in the size of the images, but if not applied on solid scientific criteria can lead to useful diagnostic information is lost. This talk takes a description and assessment of the quality of image obtained after the application of current compression codecs from analysis of physical parameters such as: Spatial resolution, random noise , contrast and image generation devices. Open for Medical Physics and Image Processing, directed toward establishing objective criteria to stop losing compression, based on the implementation of Univariate and bivariate traditional metrics such as mean square error introduced by each issue focuses rate compression, Signal to Noise peak to peak noise and contrast ratio , and other metrics, more modern, such as Structural Similarity Index and, Measures Distance , singular value decomposition of the image matrix and Correlation and Spectral Measurements. It also makes a review of physical approaches for predicting image quality from use mathematical observers as the Hotelling and Hotelling Pipeline with Gabor functions or Laguerre - Gauss polynomials . Finally the correlation of these objective methods with subjective assessment of image quality made ​​from ROC analysis based on Diagnostic Performance Curves is analyzed. (author)

Moving from job-shop to production cells without losing flexibility: a case study from the wooden frames industry

Directory of Open Access Journals (Sweden)

Dinis-Carvalho, J.

2014-11-01

Full Text Available Cellular production is usually seen as a hybrid approach between job-shop and flow-line paradigms, reducing the major disadvantages of these two paradigms: the low productivity of job-shops and the low flexibility (in terms of products’ variety of the flow-lines. This paper describes the implementation of a production cell in a production unit of wood- framed pictures and mirrors, which was originally configured as a traditional job-shop, without losing the necessary flexibility to face market demand and simultaneously increasing the production unit’s performance. By implementing a highly flexible cell, very significant improvements were expected for the system’s overall performance and the quality of the products. These expectations were met, and the implementation was successful, as demonstrated by the results presented.

Development of a commercially viable piezoelectric force sensor system for static force measurement

Liu, Jun; Luo, Xinwei; Liu, Jingcheng; Li, Min; Qin, Lan

2017-09-01

A compensation method for measuring static force with a commercial piezoelectric force sensor is proposed to disprove the theory that piezoelectric sensors and generators can only operate under dynamic force. After studying the model of the piezoelectric force sensor measurement system, the principle of static force measurement using a piezoelectric material or piezoelectric force sensor is analyzed. Then, the distribution law of the decay time constant of the measurement system and the variation law of the measurement system’s output are studied, and a compensation method based on the time interval threshold Δ t and attenuation threshold Δ {{u}th} is proposed. By calibrating the system and considering the influences of the environment and the hardware, a suitable Δ {{u}th} value is determined, and the system’s output attenuation is compensated based on the Δ {{u}th} value to realize the measurement. Finally, a static force measurement system with a piezoelectric force sensor is developed based on the compensation method. The experimental results confirm the successful development of a simple compensation method for static force measurement with a commercial piezoelectric force sensor. In addition, it is established that, contrary to the current perception, a piezoelectric force sensor system can be used to measure static force through further calibration.

Minimizing pulling geometry errors in atomic force microscope single molecule force spectroscopy.

Rivera, Monica; Lee, Whasil; Ke, Changhong; Marszalek, Piotr E; Cole, Daniel G; Clark, Robert L

2008-10-01

In atomic force microscopy-based single molecule force spectroscopy (AFM-SMFS), it is assumed that the pulling angle is negligible and that the force applied to the molecule is equivalent to the force measured by the instrument. Recent studies, however, have indicated that the pulling geometry errors can drastically alter the measured force-extension relationship of molecules. Here we describe a software-based alignment method that repositions the cantilever such that it is located directly above the molecule's substrate attachment site. By aligning the applied force with the measurement axis, the molecule is no longer undergoing combined loading, and the full force can be measured by the cantilever. Simulations and experimental results verify the ability of the alignment program to minimize pulling geometry errors in AFM-SMFS studies.

Force sharing and other collaborative strategies in a dyadic force perception task.

2018-01-01

When several persons perform a physical task jointly, such as transporting an object together, the interaction force that each person experiences is the sum of the forces applied by all other persons on the same object. Therefore, there is a fundamental ambiguity about the origin of the force that each person experiences. This study investigated the ability of a dyad (two persons) to identify the direction of a small force produced by a haptic device and applied to a jointly held object. In this particular task, the dyad might split the force produced by the haptic device (the external force) in an infinite number of ways, depending on how the two partners interacted physically. A major objective of this study was to understand how the two partners coordinated their action to perceive the direction of the third force that was applied to the jointly held object. This study included a condition where each participant responded independently and another one where the two participants had to agree upon a single negotiated response. The results showed a broad range of behaviors. In general, the external force was not split in a way that would maximize the joint performance. In fact, the external force was often split very unequally, leaving one person without information about the external force. However, the performance was better than expected in this case, which led to the discovery of an unanticipated strategy whereby the person who took all the force transmitted this information to the partner by moving the jointly held object. When the dyad could negotiate the response, we found that the participant with less force information tended to switch his or her response more often.

Stable dynamics in forced systems with sufficiently high/low forcing frequency.

Bartuccelli, M; Gentile, G; Wright, J A

2016-08-01

We consider parametrically forced Hamiltonian systems with one-and-a-half degrees of freedom and study the stability of the dynamics when the frequency of the forcing is relatively high or low. We show that, provided the frequency is sufficiently high, Kolmogorov-Arnold-Moser (KAM) theorem may be applied even when the forcing amplitude is far away from the perturbation regime. A similar result is obtained for sufficiently low frequency, but in that case we need the amplitude of the forcing to be not too large; however, we are still able to consider amplitudes which are outside of the perturbation regime. In addition, we find numerically that the dynamics may be stable even when the forcing amplitude is very large, well beyond the range of validity of the analytical results, provided the frequency of the forcing is taken correspondingly low.

High Cable Forces Deteriorate Pinch Force Control in Voluntary-Closing Body-Powered Prostheses.

Directory of Open Access Journals (Sweden)

Mona Hichert

Full Text Available It is generally asserted that reliable and intuitive control of upper-limb prostheses requires adequate feedback of prosthetic finger positions and pinch forces applied to objects. Body-powered prostheses (BPPs provide the user with direct proprioceptive feedback. Currently available BPPs often require high cable operation forces, which complicates control of the forces at the terminal device. The aim of this study is to quantify the influence of high cable forces on object manipulation with voluntary-closing prostheses.Able-bodied male subjects were fitted with a bypass-prosthesis with low and high cable force settings for the prehensor. Subjects were requested to grasp and transfer a collapsible object as fast as they could without dropping or breaking it. The object had a low and a high breaking force setting.Subjects conducted significantly more successful manipulations with the low cable force setting, both for the low (33% more and high (50% object's breaking force. The time to complete the task was not different between settings during successful manipulation trials.High cable forces lead to reduced pinch force control during object manipulation. This implies that low cable operation forces should be a key design requirement for voluntary-closing BPPs.

Malaysia and forced migration

Directory of Open Access Journals (Sweden)

Arzura Idris

2012-06-01

Full Text Available This paper analyzes the phenomenon of “forced migration” in Malaysia. It examines the nature of forced migration, the challenges faced by Malaysia, the policy responses and their impact on the country and upon the forced migrants. It considers forced migration as an event hosting multifaceted issues related and relevant to forced migrants and suggests that Malaysia has been preoccupied with the issue of forced migration movements. This is largely seen in various responses invoked from Malaysia due to “south-south forced migration movements.” These responses are, however, inadequate in terms of commitment to the international refugee regime. While Malaysia did respond to economic and migration challenges, the paper asserts that such efforts are futile if she ignores issues critical to forced migrants.

The objective of this study was to evaluate whether care provided in the care programmes matched the needs of older people. Care programmes were implemented in primary-care settings in the Netherlands to identify frail older people and to prevent further deterioration of health. In total, 23 older people participated in in-depth interviews. Within this study, three older people participated as co-researchers; they gathered and analysed the data together with the academic researchers. Content analysis was used to analyse the data. Two categories emerged from the data: 'Losing connections' and 'Receiving support to reconnect.' 'Losing connections' reflects the needs of older people and 'Receiving support to reconnect' reflects their experience and the appreciated aspects of the provided care. A relationship of trust with the practice nurse (PN) appeared to be an important aspect of care, as it fostered the sharing of feelings and issues other than physical or medical problems that could not be shared with the general practitioner. The PNs are experienced as connectors, who help to restore feelings of connectedness and older peoples' access to resources in the community. The relationship with the PN was experienced as valuable because of the feelings of 'connectedness' it created. Through this connectedness, older people could discuss feelings of loneliness, depression and frustration in receiving and acquiring the appropriate resources and services with the PNs. Furthermore, the relationship with the PN helped the older people to gain access to other health professionals and services. The results imply that care for frail older people should include an awareness of the importance of the trusting relationship. Nurses can play a vital role in creating a trusting relationship and are able to bridge the gap between older people and other professionals and services. © 2014 John Wiley & Sons Ltd.

Losing an only child: the one-child policy and elderly care in China.

Science.gov (United States)

Song, Yu

2014-05-01

China has had the one-child policy for more than 30 years. It reduced China's population growth within a short period of time and promoted economic development. However, it has also led to difficulties, and this paper focuses on those which pertain to ageing and losing one's only child. Approximately one million families have lost their only child in China. They suffer mentally and physically, and sometimes face social stigma and economic loss. What worries them most, however, is elderly care, which has become a severe crisis for the families who have lost their only children. This article draws upon several qualitative studies and 12 cases reported by the Chinese media in 2012 and 2013, and existing laws and policies for supporting those who have lost only children. It also analyses the current elderly care situation facing these families. The Chinese government has recognized the predicament and provides some help, which is increasing but is still not always adequate. To both sustain China's economic development and limit population growth, it is essential for the government to reform the one-child policy and provide a comprehensive support system for the families who have lost their only children, including financial relief and elderly care, and work to reduce stigma against these families.

A total of 51 of 89 wrestlers competing in the Estonian Championship in 2009 donated a urine sample. Questionnaire responses revealed that 27 wrestlers (body mass losers (BMLs)) reduced body mass before the competition, whereas 24 wrestlers (those who do not lose body mass (n-BMLs)) did not. In 42 wrestlers, values of urine specific gravity ≥1.020 and urine osmolality ≥700 mOsmol·kg(-1) revealed a hypohydrated status. The prevalence of hypohydration in the BMLs (96%) was higher than in the n-BMLs (67%) (χ(2) = 7.68; p 1.030) was 5.3 times greater (χ(2) = 8.32; p OWI. The prevalence of hypohydration and serious hypohydration is especially high among wrestlers who are accustomed to reducing body mass before competition. These results suggest that an effective rehydration strategy is needed for Olympic-style wrestlers, and that changes in wrestling rules should be considered to reduce the prevalence of harmful body mass management behaviours.

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

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

Hydrostatic force sensor

This paper presents a theoretical and experimental investigation of a new kind of force sensor which detects forces by measuring an induced pressure change in a material of large Poisson's ratio. In this investigation we develop mathematical expressions for the sensor's sensitivity and bandwidth, and show that its sensitivity can be much larger and its bandwidth is usually smaller than those of existing strain-gage-type sensors. This force sensor is well-suited for measuring large but slowly varying forces. It can be installed in a space smaller than that required by existing sensors

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

The Security Exercise Evaluation System (SEES) is under development for use in planning Force on Force exercises and as an aid in post-exercise evaluation. This study is part of the development cycle where the simulation results are compared to field data to provide guidance for further development of the model. SEES is an event-driven stochastic computer program simulating individual movement and combat within an urban terrain environment. The simulator models the physics of movement, line of sight, and weapon effects. It relies on the controllers to provide all knowledge of security tactics, which are entered by the controllers during the simulation using interactive color graphic workstations. They are able to develop, modify and implement plans promptly as the simulator maintains real time. This paper reports on how SEES will be used to develop an intrusion plan, test the security response tactics and develop observer logistics. A Force on Force field exercise will then be executed to follow the plan with observations recorded. An analysis is made by first comparing the plan and events of the simulation with the field exercise, modifying the simulation plan to match the actual field exercise, and then running the simulation to develop a distribution of possible outcomes

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

Science.gov (United States)

Post, P.; Kärner, O.

2009-04-01

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

Individuals with spasticity after stroke experience a decrease in force steadiness which can impact function. Alterations in the strength of EMG-force coupling may contribute to the reduction in force steadiness observed in spasticity. The aim was to determine the extent to which force steadiness and EMG-force coupling is affected by post-stroke spasticity. This cross-sectional study involved individuals with upper limb spasticity after stroke. Participants were required to generate and maintain isometric contractions of the elbow flexors at varying force levels. Coefficient of variation of force, absolute force, EMG-force cross-correlation function peak and peak latency was measured from both limbs with surface electromyography and isometric dynamometry. Statistically significant differences were observed between the affected and less affected limbs for all outcome measures. Significant main effects of force level were also observed. Force steadiness was not statistically significantly correlated with EMG-force coupling; however, both force steadiness and absolute force were associated with the level of impairment as measured by the Chedoke McMaster Stroke Assessment Scale. Spasticity after stroke uncouples the relationship between EMG and force and is associated with reduced force steadiness during isometric contractions; however, these features of control are not associated in individuals with spasticity.

The original Ampere force and Biot-Savart and Lorentz forces

International Nuclear Information System (INIS)

Pappas, P.T.

1983-01-01

The purpose of this paper is to present the results of a very simple experiment, which favours the original Ampere force and unambiguously disproves the Biot-Savart force of relativity, or its approximation in a covariant relativistic form, namely the Lorentz force. This experiment with its extra degree of freedom has the advantage over the many other similar ones, including Ampere's original experiment, which have been performed in the past and recently by Graneau, of giving results which are both qualitative and quantitative, as well as unambiguous. Due to the strong association of the Biot-Savart and Lorentz force to relativistic theories, the experiment can be also considered as limiting the generality of these theories

Interrelation between striction forces in dielectrics and optically induced forces in transparent media

International Nuclear Information System (INIS)

Torchigin, V P; Torchigin, A V

2012-01-01

Optically induced forces applied to a transparent optical medium, which is inserted in a closed plane optical resonator, are calculated by means of an analysis of the changes in the eigenfrequency and energy stored in the resonator at various positions of the medium. These forces are compared with striction forces applied to the medium considered as a dielectric placed in an alternate electrical field within the resonator. It is shown that the optically induced forces are equal to the striction forces. The results of using the classical formula for striction forces in electrostatics are considered. (paper)

Modeling chemical gradients in sediments under losing and gaining flow conditions: The GRADIENT code

Science.gov (United States)

Boano, Fulvio; De Falco, Natalie; Arnon, Shai

2018-02-01

Interfaces between sediments and water bodies often represent biochemical hotspots for nutrient reactions and are characterized by steep concentration gradients of different reactive solutes. Vertical profiles of these concentrations are routinely collected to obtain information on nutrient dynamics, and simple codes have been developed to analyze these profiles and determine the magnitude and distribution of reaction rates within sediments. However, existing publicly available codes do not consider the potential contribution of water flow in the sediments to nutrient transport, and their applications to field sites with significant water-borne nutrient fluxes may lead to large errors in the estimated reaction rates. To fill this gap, the present work presents GRADIENT, a novel algorithm to evaluate distributions of reaction rates from observed concentration profiles. GRADIENT is a Matlab code that extends a previously published framework to include the role of nutrient advection, and provides robust estimates of reaction rates in sediments with significant water flow. This work discusses the theoretical basis of the method and shows its performance by comparing the results to a series of synthetic data and to laboratory experiments. The results clearly show that in systems with losing or gaining fluxes, the inclusion of such fluxes is critical for estimating local and overall reaction rates in sediments.

Crowding in the city: losing and winning competitors of an invasive bird.

Full Text Available Invasive species can take advantage of resources unexploited by natives (opportunism hypothesis or they can exploit the same resources but more aggressively or efficiently (competition hypothesis, thus impacting native species. However, invasive species tend to exploit anthropogenic habitats that are inefficiently used by natives such as urban environments. Focusing on the ring-necked parakeet (Psittacula krameri, one of the most invasive birds worldwide, we combined observations of interspecific aggressions, species-specific cavity-nest preferences and the spatial distribution of the native cavity-nesting vertebrate community to determine the invasion process as well as its potential impacts on native species in a Mediterranean city. Our results support the competition hypothesis, suggesting that ring-necked parakeets are outcompeting native species sharing nest-site preferences. Parakeets initiated and won most interspecific aggressions, which were directed towards competitors but also towards predators. This behaviour could explain the spatial arrangement of natives, with most bird species breeding close to parakeets possibly to take advantage of their effective antipredatory behaviour. However, temporal and spatial patterns of segregation suggest that a threatened bat species is negatively affected by parakeets. This demonstrates that common species gain benefits and threatened ones (in this study, a bat and possibly a falcon lose nest sites due to invaders. Therefore, the conservation status of the native species that pay the costs of competition with invaders should be considered. This scenario of winners and losers may, however, shift towards more losers if the ring-necked parakeet population continues to grow, thus requiring close monitoring and control/eradication programs to avoid further impacts.
