    International Nuclear Information System (INIS)

    According to the Convention on Nuclear Safety, Bulgaria should ensure that sufficient numbers of qualified staff with appropriate education, training and retraining are available for all safety related activities in or for each nuclear installation, throughout its lifetime. The development of the nuclear sector is closely related to the education and training of a sufficient number of skilled and qualified specialists in the following directions: - Fundamental and application nuclear science; - Nuclear energetic; - Nuclear I and C industry and microelectronics; - Civil engineering; - Nuclear safety and emergency planning; - Ecology and radioactive waste management; - Economical aspects of nuclear technology; - Security of nuclear installations and non-proliferation. The development and maintenance of a state of the art system for education and training of nuclear installations personnel is crucial for the safety and the reliable and efficient operation of nuclear power plants. The major task of the government, academic community and nuclear industry sector is to preserve existing nuclear expertise and to implement a successive approach to set up a three level qualified personnel - undergraduate education, graduate and post-graduate education and specialized training. Education in Nuclear Science at university level in Bulgaria exists since 1939, when E. Karamihailova began to teach a course on Experimental Atomic Physics and Radioactivity at the University of Sofia. A few years later (1945) she founded the Department of Atomic Physics. Later, in 1962 K. Kostadinov gave the first lectures in radiochemistry as an optional course at the Faculty of Chemistry. Specialized education at the MSc level started in 1972: in nuclear engineering at the Faculty of Physics and in radiochemistry at the Faculty of Chemistry, both at the University of Sofia. Nowadays, there are three departments at the University of Sofia, which, along with the Technical University of Sofia, form

    Antonova, J

    2007-06-01

    A survey of the state of pharmacy in medieval Bulgaria is done, analyzing written records of various origin and content. Written documents are reviewed separately in chronological order. They all seem to lend support to the conclusion that realism is a characteristic feature of pharmacy in medieval Bulgaria. Mysticism and superstition are relatively rarely resorted to, precedence is given to real treatment with suitable and not so suitable medical plants, minerals and animal products. Relatively weak is the impact of West-European medicine and pharmacy because of the different influence of the Eastern and the Western Orthodox religion, and partly because of the territorial remoteness. During the High Middle Ages Bulgarian pharmacy developed under the influence of Hellenic ancient culture. Later, after the 15 century, the influence of the Arabian culture and medicine is also felt as a result of the complex compilation between the Bulgarian and Ottoman culture during the 500-year Turkish yoke.

  8. Public Information in Bulgaria

    International Nuclear Information System (INIS)

    The nuclear power program started in Bulgaria by the construction of Kozloduy NPP where the units 1 to 4 (WWER 440/B-230 reactors) were commissioned in 1974, 1975, 1980 and 1982. Units 5 and 6 (WWER 1000/B-320) were put in operation in 1988 and 1993, respectively. Kozloduy NPP share in the total electricity generation in Bulgaria is ∼ 45%. The following main principles of the information policy are discussed: - The public should be openly, clearly and consistently informed about all issues impacting its safety and prosperity; - The nuclear program is one of the basic elements supporting the country economics and the necessary component of the solid energy industry. As objectives, this activity has the goals to accumulate the capital of public trust towards Kozloduy NPP as a safe, reliable and environment friendly source of energy and to gain public support to further development of the nuclear power industry in Bulgaria. As strategies and tactics one acts towards: creation of transparent information medium of the plant work; creation of a favourable public image of the plant; proactive approach to key opinion makers; enhancement of the public nuclear culture; provision of constant flow of reliable information on the status of the plant, safety and environment; systematic approach to the public relation (PR) programs; implementation of good practices and cooperation with PR services. The Kozloduy NPP Information Center and PR activities are then presented. The talk ends with a review of the media image of nuclear industry in Bulgaria. It results that the Nuclear Energy is attacked rather by the politicians than by the experts (35% vs 26%) and is defended rather by the experts than by politicians (48% vs 25%). Also, one finds that 54% of the publications are neutral, 30% are optimistic while 16% are catastrophic

  13. Chemical Education in Bulgaria

    Garkov, Vladimir N.

    1999-08-01

    The sociopolitical changes in Eastern Europe of the 1990s and the ongoing globalization of the chemical industry and chemical education prompted this analysis of the current status of chemical education in Bulgaria, which is not very different from the educational practices in the rest of Europe. The level of chemistry knowledge expected from all high-school graduates in Bulgaria is roughly equivalent to the general and organic chemistry courses for science majors at U.S. universities. The newly introduced four-year bachelor's degree curriculum (based on 15-week semesters) at the University of Sofia includes a core of 106 semester hours (labs counted as 1 hour each), 41 semester hours of electives, and 445 contact hours (11 weeks) of research, which ends with a thesis defense. The instructional techniques in Bulgaria are subject-centered and follow the hierarchical structure of knowledge in an integrated and unitary manner. In conclusion, the Bulgarian system of education in chemistry aims at preparing a scientifically literate citizenry and broadly trained chemists by imposing a very challenging and rigid curriculum with very few choices. It is speculated that the laissez-faire climate of free intellectual initiative seen only at American universities provides a more appropriate environment for talent encouragement and scientific innovation for overseas-educated undergraduate and graduate students than their home institutions.

The creation of a National Register for Individual Doses is a major task still awaiting solution

  16. Uranium geology of Bulgaria

    International Nuclear Information System (INIS)

    Three major uranium districts containing several deposits, plus 32 additional deposits, have been identified in Bulgaria, all of which are detailed geologically in this article. Most of the deposits are located in the West Balkan mountains, the western Rhodope mountains, and the Thracian Basin. A few deposits occur in the East Balkan, eastern Rhodope and Sredna Gora mountains. The types of deposits are sandstone, vein, volcanic, and surficial. Sandstone deposits are hosted in Permian and Tertiary sediments. In early 1992, fifteen deposits were being exploited, of which roughly 70 percent of the uranium produced was being recovered using in-situ leaching (ISL) methods. The remainder was being recovered by conventional underground mining, except for one small deposit that utilized open-pit methods. Fifteen other Bulgarian deposits had been exhausted, while five deposits were still in the exploration stage. Uranium production began in Bulgaria in 1946, and cumulative production through 1991 exceeded 100 million pounds equivalent U3O8. Current annual production is on the order of one million pounds equivalent U3O8, about 750 thousand pounds of which are recovered by ISL operations

    In the last 20 years, demographic development in Bulgaria has been characterized by population decline, a low crude birth rate, a low fertility rate, a high mortality rate and an ageing population. A stabilizing political situation since the early 2000s and an economic upsurge since the mid-2000s were important factors in the slight increase of the birth and fertility rates and the slight decrease in standardized death rates. In general, Bulgaria lags behind European Union (EU) averages in most mortality and morbidity indicators. Life expectancy at birth reached 73.3 years in 2008 with the main three causes of death being diseases of the circulatory system, malignant neoplasms and diseases of the respiratory system. One of the most important risk factors overall is smoking, and the average standardized death rate for smoking-related causes in 2008 was twice as high as the EU15 average. The Bulgarian health system is characterized by limited statism. The Ministry of Health is responsible for national health policy and the overall organization and functioning of the health system and coordinates with all ministries with relevance to public health. The key players in the insurance system are the insured individuals, the health care providers and the third party payers, comprising the National Health Insurance Fund, the single payer in the social health insurance (SHI) system, and voluntary health insurance companies (VHICs). Health financing consists of a publicprivate mix. Health care is financed from compulsory health insurance contributions, taxes, outofpocket (OOP) payments, voluntary health insurance (VHI) premiums, corporate payments, donations, and external funding. Total health expenditure (THE) as a share of gross domestic product (GDP) increased from 5.3% in 1995 to 7.3% in 2008. At the latter date it consisted of 36.5% OOP payments, 34.8% SHI, 13.6% Ministry of Health expenditure, 9.4% municipality expenditure and 0.3% VHI. Informal payments in the health

    Eros and Psyche is a club for adolescents based in a youth center in Sofia, Bulgaria. Eros, the ancient Greek god of love, and Psyche, representing the human soul, symbolize the club's activities relating to the psychological and aesthetic aspects of sexuality. The club was started in December 1988 to provide sex education to out-of-school youth, the first attempt to move away from restrictive, medical approaches. Members include pupils, students, workers and even parents. The club meets twice a week for two hours, with specialists from different fields addressing the group, videos, readings and other activities that stimulate discussion. Anyone is free to come and go. Twice a year the club holds training sessions in psychosocial skills that aim to promote self-reflection and help people interact more openly with one another. Each individual is helped to find a personal route to understanding his or her own sexuality. Other clubs have been formed on the Sofia model. To help them organize, the Sofia club has prepared a leaders' manual and is developing a one-week course for club leaders. PMID:12346874

    International Nuclear Information System (INIS)

    After the construction of NPP Belene has been stopped in 1990, 4 attempts are made for the development of a new nuclear power unit in Bulgaria. In accordance with the regulations the following principles and criteria are considered - the probabilistic assessment should ensure frequency for the core integrity damage -5 1/reactor years; frequency of the radioactive release in case of beyond design basis accident -6 1/reactor. Comparison of different projects and perspective for NNPs in various countries is made. Analysis of technical solutions for safety and reliability is made, considering the modernization programme for the Kozloduy NPP units 5 and 6 and the experience of other power plants. In connection with the planning of a new nuclear power unit the following items are discussed: characteristics of the Kozloduy site and Belene site (variants of general plans are studied); finance analyses; technical analyses; legislation. The main conclusions about the new power unit construction is that the Belene NPP is the project which would be the most competitive on the energy market and it is expected to bring the most investment returns. It is stated that the completion of the Belene NPP unit 1 using the Improved Project B-320M is technically and financially substantiated, profitable and without alternative

Stakeholders and their interests and preferences in coppice forests are explored and assessed. Forests restitution process in Bulgaria started in 1997 and has not been finished yet. Nevertheless, significant further changes of the current ownership distribution are not expected. By the end of 2007, the state was the biggest coppice forest owner/stakeholder in Bulgaria with 71.3% of all coppice forests being state property. The other two important stakeholders are the municipalities (14.0% and private owners (12.0%. Currently, forest owners' number in Bulgaria exceeds 1 million, the average holding area being smaller than 1 ha. Only 150 individual plots are larger than 50 ha. The majority of private owners aim at taking maximum and immediate profit from their recently restituted forest properties. In most cases that reflects in clearcuts. Coppice forests management has been one of the problematic issues of Bulgarian forestry for decades. Despite of forest authorities significant efforts, the area of coppice forests in Bulgaria (1.78 million ha in 2007 remained unchanged for a period of 50 years. The official forest policy is still aimed at conversion of coppice forests into seed ones through different silvicultural methods. That policy is applied to almost all coppice forests regardless of their ownership.

  14. Circulation factors affecting precipitation over Bulgaria

    Science.gov (United States)

    Nojarov, Peter

    2015-09-01

    The objective of this paper is to determine the influence of circulation factors on precipitation in Bulgaria. The study succeeds investigation on the influence of circulation factors on air temperatures in Bulgaria, as the focus here is directed toward precipitation amounts. Circulation factors are represented through two circulation indices, showing west-east or south-north transport of air masses over Bulgaria and four teleconnection indices (patterns)—North Atlantic Oscillation, East Atlantic, East Atlantic/Western Russia, and Scandinavian. Omega values at 700-hPa level show vertical motions in the atmosphere. Annual precipitation trends are mixed and not statistically significant. A significant decrease of precipitation in Bulgaria is observed in November due to the strengthening of the eastward transport of air masses (strengthening of EA teleconnection pattern) and anticyclonal weather (increase of descending motions in the atmosphere). There is also a precipitation decrease in May and June due to the growing influence of the Azores High. An increase of precipitation happens in September. All this leads to a redistribution of annual precipitation course, but annual precipitation amounts remain the same. However, this redistribution has a negative impact on agriculture and winter ski tourism. Zonal circulation has a larger influence on precipitation in Bulgaria compared to meridional. Eastward transport throughout the year leads to lower than the normal precipitation, and vice versa. With regard to the four teleconnection patterns, winter precipitation in Bulgaria is determined mainly by EA/WR teleconnection pattern, spring and autumn by EA teleconnection pattern, and summer by SCAND teleconnection pattern.

  1. Bulgaria: INIS Center - 45 years experience

    International Nuclear Information System (INIS)

    Bulgaria is one of 35 countries in the world operating nuclear power plants. Bulgaria's nuclear program was launched in 1956 with the construction of an IRT-2000 research reactor at the Institute for Nuclear Research and Nuclear Energy (INRNE), which was commissioned in 1961. The reactor is now under reconstruction. In 1960, construction of the first Bulgarian nuclear power plant started. At the moment, there are 6 power units at the Kozloduy NPP site; 4 of them (VVER-440/B-230) under decommissioning and 2 (VVER-1000/B-320) in operation. Several storage facilities for radioactive waste, mainly from the Kozloduy NPP and from various sources of ionizing radiation in medicine and industry are also in operation. The Kozloduy NPP, INRNE, Sofia University, the Technical University, and the State Enterprise Radioactive Waste are the main generators of nuclear information in Bulgaria and the main consumers of INIS products. The Bulgarian INIS Center, therefore, maintains continuous and effective cooperation with these Institutions

  2. Bulgaria: Ethnic differentials in rapidly declining fertility

    2008-07-01

    Full Text Available This chapter provides a detailed description of the fertility changes in Bulgaria during recent decades and discusses possible reasons and consequences. It also gives an overview of the steps that the government has undertaken to offset the considerable decline in fertility. Before the fall of communism, fertility trends in Bulgaria were stable and characterized by a nearly universal entry into parenthood, dominance of a two-child family model, an early start and early end of childbearing, stable mean ages at entry into childbearing and marriage, and low percentages of non-marital births. During the 1990s and in the first years of the new century, we observe a marked, rapid change in fertility behaviour. Together with the severe decline in overall fertility rates, demographic data reveal a significant postponement of entry into motherhood and marriage, a decline of the two-child family model, and an emergence of new family forms. Most research attributes these changes to the particular political and social situation in Bulgaria since 1989.

  6. Induced Mutagenesis for Crop Improvement in Bulgaria

    International Nuclear Information System (INIS)

    Experimental mutagenesis has been investigated and applied in crop breeding in various Bulgarian agricultural research institutes during the last half century. In this paper some major accomplishments achieved in Bulgaria are highlighted. Both, physical mutagens (mainly gamma rays) and chemical mutagens (mainly EMS, NMU, NEU), have been used and their proper doses have been established. According to the information available to the author, there are more than 76 new cultivars developed using induced mutants in Bulgaria, namely: barley (5), wheat (5), durum wheat (9), maize (26), sunflower (3), lentil (4), bean (2), pea (1), chickpea and vetch (2), soybean (5), tomato (6), pepper (4), cotton (2), tobacco (2). Some of the mutant cultivars such as maize hybrid Kneja 509 and durum wheat cultivar Gergana have become leading cultivars occupying up to 50% of the growing area of the crop concerned. In durum wheat, mutant cultivars have not only covered almost all the growing areas but also doubled the yield in the past 30 years. The achievements in mutation breeding programmes have also had a significant impact on the progress of genetic research by elucidating the underlying mechanisms of induced mutations and the training of many young researchers and university students through their involvement in various research projects. A number of mutant lines with novel characteristics and mutant cultivars of economical importance together with relevant techniques used in the development and characterization of those mutant lines/cultivars are described in this paper.

  10. Options for Bulgaria power system extension planning

    International Nuclear Information System (INIS)

    Under the existing transition to market economy in Bulgaria, the planning of development of electricity generation is among the priorities of the national policy of restructuring and renovation of electricity system in the country. Optimal plans for development of the generation capacity are worked out by means of optimization procedure part of ENPEP package (ELECTRIC module) based on the dynamic programming technique. The optimal plans study three main strategies for development of energy capacities, which have to do with the priority of some type of natural resources--Coal, Natural Gas and Nuclear Energy. The Hydro Power Plant construction and loading schedule for each scenario is different and it harmonized with the maneuverability of other capacities. Coal scenario emphasizes the opportunities for the maximizing of local coal mining, substitution of black coal (energy and coke) import by mining of local coal fields and implementation of efficient and environmentally sound technologies when constructing new thermal power plants. Gas scenario envisages natural gas consumption within the limit of existing capacities of the national and transit pipelines. In this connection, the share of the new generating capacities using combined cycle increases their share. Nuclear scenario assumes increased share of the nuclear units at the expense of local coal mining and natural gas. This is due to the rehabilitation of 1,000 MW units in NPP Kozloduy, completion of a 1,000 MW unit in new NPP and construction of 1--2 new units 600 MW after 2010. The data obtained outlines the perspectives for development of energy generation capacities in Bulgaria for the period 2000--2020, tendencies in the generation structure and the share of each different type of generation units in the structure of electricity generation system. Output information serves as a sound base for conclusions on the advantages and disadvantages of the three strategies

    2001-06-01

    Full Text Available The Kresna earthquake in 1904 in Bulgaria is one of the largest shallow 20th century events on land in the Balkans. This event, which was preceded by a large foreshock, has hitherto been assigned a range of magnitudes up to M S = 7.8 but the reappraisal of instrumental data yields a much smaller value of M S = 7.2 and a re-assement of the intensity distribution suggests 7.1. Thus both instrumental and macroseismic data appear consistent with a magnitude which is also compatible with the fault segmentation and local morphology of the region which cannot accommodate shallow events much larger than about 7.0. The relatively large size of the main shock suggests surface faulting but the available field evidence is insufficient to establish the dimensions, attitude andamount of dislocation, except perhaps in the vicinity of Krupnik. This downsizing of the Kresna earthquake has important consequences for tectonics and earthquake hazard estimates in the Balkans.

    Full Text Available Abstract Background Haemophilias are the most common hereditary severe disorders of blood clotting. In families afflicted with heamophilia, genetic analysis provides opportunities to prevent recurrence of the disease. This study establishes a diagnostical strategy for carriership determination and prenatal diagnostics of haemophilia A in Bulgarian haemophilic population. Methods A diagnostical strategy consisting of screening for most common mutations in the factor VIII gene and analysis of a panel of eight linked to the factor VIII gene locus polymorphisms was established. Results Polymorphic analysis for carrier status determination of haemophilia A was successful in 30 families out of 32 (94%. Carrier status was determined in 25 of a total of 28 women at risk (89%. Fourteen prenatal diagnoses in women at high risk of having a haemophilia A – affected child were performed, resulting in 6 healthy boys and 5 girls. Conclusion The compound approach proves to be a highly informative and cost-effective strategy for prevention of recurrence of haemophilia A in Bulgaria. DNA analysis facilitates carriership determination and subsequent prenatal diagnosis in the majority of Bulgarian families affected by haemophilia A.

    Full Text Available IT outsourcing is among the prevalent practices in the global business today. It is found that business organizations decide to transfer such kind of services to other firms (identified as “vendors” mainly because of cost-related advantages. It is still not clear whether the vendors are able to provide comparative advantages from the point of view of economizing costs of the production of these services. The objective of this paper is to identify the main determinants affecting the success of IT outsourcing partnership in Bulgaria on the basis of empirical study. The paper presents selected results from a survey of the outsourcing relations between Bulgarian vendor organizations and their clients (outsourcers considering the issues of the development of successful strategic partnerships in outsourcing practices. In 2008 an empirical survey of outsourcing partnerships in 28 organizations providing high technology services has been conducted based on cases of Bulgarian vendor organizations. The subject of the study was the analysis of the key determinants influencing the formation and development of strategic outsourcing partnerships between Bulgarian vendor organizations and their clients (foreign companies.

  19. Economical issues on radiotherapy establishment in Bulgaria

    International Nuclear Information System (INIS)

    On the ground of accurate cost analysis for construction and operation of a new radiotherapy center an average cost of radiotherapy (RT) per patient in Bulgaria has been estimated. There is a lack of Bulgarian economical standard for RT center. As a country of comparable population and cancer incidence rate Belgian economical approach was implemented. A base for standard cost for RT are investment costs for buildings, installations, salaries and supply in ratio of 5 : 72 : 7 : 12 : 4. A minimal cost per patient was worked out for a big center if 1500 - 2000 cases are treated per year. It is calculated to be 750 - 800 Euro for regular treatment and up to 900 Euro, if high technology is applied. Comparison to standard cost per patient in USA and European Community countries reveals 3.5 - 5 fold lower figures. The reason is a different cost structure: mainly very low expenses foe salaries, lower prices for buildings and other hospital expenditure. High technology appliance is not cost effective for the small RT centers. The initial investment of 20 - 25 mill Euro are urgently needed to decrease partly the gap between European and Bulgarian RT. Providing such funds is of fundamental importance for Bulgarian RT. (authors)

  2. Analysis of Climate Change in Southeastern Bulgaria and Northwestern Turkey

    International Nuclear Information System (INIS)

    An analysis of climate change in two neighbor regions in Bulgaria and Turkey was done. Annual and seasonal variability of air temperature and precipitation in Southeastern Bulgaria and Northwestern Turkey during the period 1961-2000 was studied. Different sources were used to complete the required input weather data. For assessing climate trends some techniques such as anomalies, polynomial, linear fit, moving average as well as the Mann-Kendall test were applied. Drought episodes during the late 20th century in the selected regions were defined and discussed. Climate change scenarios for the 21st century (e.g. 2020, 2050, 2080) were also created for Southeastern Bulgaria and Northwestern Turkey. HadCM3 scenarios (including A2 and B2 IPCC SRES emission scenarios) with high resolution (10'x 10') were applied for this purpose. A special attention was paid on the projected precipitation.

  3. Bulgaria: Novi Han radioactive waste repository

    International Nuclear Information System (INIS)

    The Novi Han radioactive waste repository is the only national radioactive waste disposal site in Bulgaria. It is located in Losen mountain, 6.5 km from the small village of Novi Han and 35 km from the capital, Sofia. The repository accepts radioactive waste generated from nuclear applications in industry, medicine, research and education. The facility was constructed according to a modified Soviet design (type TP-4891). Its construction licence was issued in 1959 and that for commissioning in 1964. The repository was specially built for the needs of the IRT-2000 research reactor operated by the Institute of Physics and other academic and medical facilities. In 1959, the Government appointed the Physical Institute of the Bulgarian Academy of Sciences, whose successor is now the Institute for Nuclear Research and Nuclear Energy (INRNE), as the central authority for the collection and disposal of radioactive waste from nuclear applications. The Novi Han repository site covers an area of 4.25 ha.1 The site is divided into two areas separated by a fence. One area contains the administrative buildings, garage and maintenance shops. The other contains the disposal facilities, radiochemical laboratory and decontamination station. The repository consists of (1) a concrete vault for low and intermediate level solid wastes, which consists of 3 separate cells with a total volume of 237 m3, (2) a concrete vault for biological wastes with a volume of 80 m3, (3) four steel tanks for storage of low level liquid wastes with a total volume of 48 m3, (4) a special 1 m3 concrete vault for spent sealed sources and (5) a concrete trench for solid waste, which consists of 7 separate units with a total volume of 200 m3.

    Full Text Available There is much evidence that ankylosing spondylitis (AS is a disease that is also much older than early human civilizations and man as a whole. Until now, the Russia's earliest (14th c ntury archaeological finding of such a patient remains a Volga Bulgaria inhabitant suffering with AS during his life. In the Republic of Tatarstan, at the site of an ancient Bulgar settlement appearing in the early ninth century, archaeologists have discovered an unusual grave: the deceased sitting with his back against the western wall of a tomb pitand having a bronze crosslet under his fingers. According to a historical source, it was the way of burying Christian hierarchs as pastors sitting on the altar and anticipating the great assize during which the destinies of human souls should be ruled. Anthropological analysis showed that the bones belonged to a 35–45-year-old man who was 158–163 cm tall. During the examination of the remains,attention was called to the following features of the spinal structure: ankylosis of the inferior cervical and superior thoracic vertebrae (СV–ThI and inferior thoracic and lumbar spine (ThIV–LII predominantly due to ossification of the anterior longitudinal ligament. Facet vertebral joints and costotransverse joints were also ankylosed at the same levels. The man's neck was fixed in a bent-over position with the head down, the chin touching the breast bone – the socalled soliciting posture. By and large, the vertebral changes are characteristic of late (X-ray stage III spondylitis. Spinal and pelvic photos and X-films are given for demonstration. The studies conducted by historical scientists and forensic medical experts suggest that the found remains are most likely to belong to Christian Theodore nicknamed Jerusaleman, also further known as Holy Theodore philosopher Kamsky (Bulgarian, who was mentioned in the Nikon chronicle in 1323.

  6. Market Report : The electrical power markets in Romania and Bulgaria

    International Nuclear Information System (INIS)

    Romania and Bulgaria want to attract foreign investment for the rehabilitation of their electric power sectors to meet the requirements for membership to the European Union. In 2000, world exports of power equipment to both countries reached $857 million, an increase of 23 per cent from 1999. This report describes the potential for Canadian exports of electric power equipment and services to work in Romania and Bulgaria. In Romania, the electric power market is expected to growth by almost 20 per cent to $550 million by the end of 2001. The major current investment is in the completion of the second unit of the Cernavoda nuclear power plant, the completion of unfinished hydroelectric power plants, and the rehabilitation of the country's power transmission and distribution system. In Bulgaria, the market is also expected to grow as the infrastructure for the thermal and hydroelectric power plant is upgraded. Bulgaria is also launching a nuclear energy program which includes modernizing older units and the construction of one new plant to increase generation capacity. Opportunities for Canadian companies will lie in the areas of cogeneration equipment, modernizing coal-fired power plants, boilers and turbines. Other opportunities lie in the areas of hydroelectric and nuclear power plants, including their control devices, voltage breakers, and equipment related to power distribution and transmission. It is recommended that Canadian companies work in cooperation with the Canadian Embassy in Bucharest and the Canadian Consulate General in Sofia. refs., tabs

    2014-01-01

    Crimean-Congo hemorrhagic fever (CCHF), which is endemic in Bulgaria, is caused by the Crimean-Congo hemorrhagic fever virus (CCHFV). The seroprevalence of CCHFV in southeastern Bulgaria was examined in this study. For this purpose, a total of 751 human blood samples were collected and examined by indirect immunofluorescence assay. In addition, a questionnaire was completed for every participant. Anti-CCHFV antibodies were detected in 3.20% (24/751) of the tested sera. None of the seropositive individuals had a history of CCHF. The results indicate that the proportion of positive findings increase with age. The significant risk factors for CCHFV infection are tick bites (18.85%, 23/122), livestock breeding (6.15%, 16/260), and residing in rural areas (6.20%, 21/339). PMID:25241694

    National Health Insurance Fund in Bulgaria on the stability of the healthcare insurance model and the implementation of the budget for 2014. Results: The results from the current analysis indicate that the growth of public expenditure is directly proportional to the number of reimbursed medical products and that the pattern of prescriptions including the innovative medical products mainly for the treatment of oncological and rare diseases has a significant impact on it. Conclusion: The reasons for the increase of public expenditure in Bulgaria include the non-transparent decisions in pricing and reimbursement of the products, the lack of guidelines for presenting pharmacological evidence and the lack of legislatively-defined drug policies for the management and control of the patterns of medical prescriptions.

    Full Text Available The information presented in this paper is based on repeated ethnographic fieldwork carried out in Bulgaria between 2008 and 2011. The aim of this study is to highlight the conceptual field of the ‘minority’ category and, in particular, of the construction of a ‘problematic minority’ in Bulgarian public discourse. First, the article focuses on the broad context of the concept of minority in Bulgaria illustrated by stereotypical statements of the Prime Minister Boyko Borissov. Next, the construction of a ‘problematic minorities’ category will be examined. We closely observe the stereotypes linked to the image of ‘Turks’, with particular attention to their presence in everyday speech.

This paper documents that the strength of this association has doubled in Bulgaria since the end of ...

  10. Computer simulations of the atmospheric composition climate of Bulgaria

    International Nuclear Information System (INIS)

    Some extensive numerical simulations of the atmospheric composition fields in Bulgaria have been recently performed. The US EPA Model-3 system was chosen as a modelling tool. As the NCEP Global Analysis Data with 1 degree resolution was used as meteorological background, the MM5 and CMAQ nesting capabilities were applied for downscaling the simulations to a 3 km resolution over Bulgaria. The TNO emission inventory was used as emission input. Special pre-processing procedures are created for introducing temporal profiles and speciation of the emissions. The biogenic emissions of VOC are estimated by the model SMOKE. The simulations were carried out for years 2000-2007. The numerical experiments have been carried out for different emission scenarios, which makes it possible the contribution of emissions from different source categories to be evaluated. The Models-3 Integrated Process Rate Analysis option is applied to discriminate the role of different dynamic and chemical processes for the air pollution formation. The obtained ensemble of numerical simulation results is extensive enough to allow statistical treatment calculating not only the mean concentrations and different source categories contribution mean fields, but also standard deviations, skewness, etc. with their dominant temporal modes (seasonal and/or diurnal variations). Thus some basic facts about the atmospheric composition climate of Bulgaria can be retrieved from the simulation ensemble. (Author)

    2016-01-01

    Full Text Available This study aimed to analyse the prevalence of American foulbrood and Paenibacillus larvae genotypes in Bulgaria. For this purpose, data concerning American foulbrood outbreaks were used. Also, available data on the number of destroyed bee families covering a twenty-five-year period (1989 - 2013 was collected from the register of Bulgarian Food Safety Agency. In addition, Paenibacillus larvae genotypes in 15 apiaries were established by rep - PCR with BOXA1R and MBOREP1 primers. Results showed broad incidence of the disease, particularly at the beginning of the analysed period, with a tendency to reduction of affected apiaries and bee families at the end of the period. A statistically significant prevalence of American foulbrood in South Bulgaria compared to the northern regions was observed. Genotyping of Paenibacillus larvae revealed two genotypes: ab and AB, with the preponderance of the more virulent AB in South Bulgaria. The obtained results showed the need for conducting regular mandatory screening of bee colonies for early diagnostics of the disease and the implementation of relevant measures for American foulbrood prevention and control.

  14. Rainfall variability in Bulgaria and its relation with NAO

    International Nuclear Information System (INIS)

    The variation of climate exerts strong influence on the productivity of agriculture and on the various aspects of human activity. Many research programs at local, regional and global levels show as a main task the action to reduce, avoid, and better understand the risk associated with the climate change. The precipitation determines the availability of drinking water and the level of the soil moisture. The paper is intended to provide information about seasonal and geographical variation of precipitation in Bulgaria and its relation with North Atlantic Oscillation (NAO). A Statistical test is applied to test the homogeneity and distribution of the initial data. In order to characterize the long-term and more recent trends linear regression equations are calculated. Correlation analysis is used to define the relationship between precipitation and global circulation mechanisms. The main question of the research is: whether the observed trend in Bulgaria corresponds to the global climate change? The tasks are: - Investigation of short-term and long-term rainfall variability - Assessment of statistical significance of the linear trend - Establishing the relationship between rainfall variability and NAO - what is the influence of the NAO on rainfall variability in Bulgaria In order to characterize the long-term and more recent trends linear regression equations were calculated individually for each station for two periods 1931-2000 and 1961-2000. The trend is negative or close to 0 for the first period. For the second period it is a negative with the values for January to April between -0.2 and -0.7. Correlation analysis is applied to define the relationship between rainfall variability in Bulgaria and NAO. The relationship is stronger for more recent period 1960-2000. The correlation coefficients are negative. Statistical significant coefficients are found for January, February and March. The paper gives information about climate change in regional scale.

  18. Reforming health care financing in Bulgaria: the population perspective.

    Science.gov (United States)

    Balabanova, Dina; McKee, Martin

    2004-02-01

    Health financing reform in Bulgaria has been characterised by lack of political consensus on reform direction, economic shocks, and, since 1998, steps towards social insurance. As in other eastern European countries, the reform has been driven by an imperative to embrace new ideas modelled on systems elsewhere, but with little attention to whether these reflect popular values. This study explores underlying values, such as views on the role of the state and solidarity, attitudes to, and understanding of compulsory and voluntary insurance, and co-payments. The study identifies general principles (equity, transparency) considered important by the population and practical aspects of implementation of reform. Data were obtained from a representative survey (n=1547) and from 58 in-depth interviews and 6 focus groups with users and health professionals, conducted in 1997 before the actual reform of the health financing system in Bulgaria. A majority supports significant state involvement in health care financing, ranging from providing safety net for the poor, through co-subsidising or regulating the social insurance system, to providing state-financed universal free care (half of all respondents). Collectivist values in Bulgaria remain strong, with support for free access to services regardless of income, age, or health status and progressive funding. There is strong support (especially among the well off) for a social insurance system based on the principle of solidarity and accountability rather than the former tax-based model. The preferred health insurance fund was autonomous, state regulated, financing only health care, and offering optional membership. Voluntary insurance and, less so, co-payments were acceptable if limited to selected services and better off groups. In conclusion, a health financing system under public control that fits well with values and population preferences is likely to improve compliance and be more sustainable.

    2014-11-01

    Full Text Available Dieser Beitrag liegt nur in englischer Sprache vor.This paper aims to illuminate and provide a critical assessment of the nationalist discourse on declining population in Bulgaria. Nationalist discourse is one of the mainstream approaches in Bulgaria and is widely spread through mass media having been voiced by renowned intellectuals, policy experts, scholars and media celebrities. It can be recognised in the political programmes of left-wing and nationalist parties, but also in governmental documents at both national as well as regional levels. The nationalistically oriented advocates articulate current concerns regarding the declining birth rates and declining population in the country labelling the demographic situation as “Bulgarian national catastrophe” and “Bulgaria’s collapse”. They place an emphasis on the decreasing proportion of ethnic Bulgarians and the growth of the ethnic minorities, especially Roma. The latter trend was labelled by the derogatory term “gypsyisation”, i.e. a distortion of the Bulgarian nation and shrinkage of its core ethnicity – ethnic Bulgarians. The threat of the “gypsyisation” of the Bulgarian nation has not only been viewed in quantitative terms, but also through the lens of an alleged worsening of the national human capital (e.g. level of education, professional skills and civic culture of the population. Another set of arguments exploited in the nationalist discourse is the diminishing size of the Bulgarian nation as a threat to national sovereignty, territorial unity and economic stability. We use a qualitative content analysis and thematic analysis of media textual materials in order to reconstruct the main ideas, arguments and strategies of the proponents of the nationalist discourse regarding the consequences of the declining population in Bulgaria, its social policy implications and future demographic prospects.

  20. Hazard assessment for Romania–Bulgaria crossborder region

    International Nuclear Information System (INIS)

    Among the many kinds of natural and man-made disasters, earthquakes dominate with regard to their social and economical impact on the urban environment. Global seismic hazard and vulnerability to earthquakes are steadily increasing as urbanisation and development occupy more areas that are prone to effects of strong earthquakes. The assessment of the seismic hazard is particularly important, because it provides valuable information for seismic safety and disaster mitigation, and it supports decision making for the benefit of society. The main objective of this study is to assess the seismic hazard for Romania-Bulgaria cross-border region on the basis of integrated basic geo-datasets

The main topics covered are: estimated energy reserve; energy balance, new capacities, installed in 2002; information about the WWER-230 reactors operation; environmental impact and global warming; Bulgarian export and regional electricity demand; public opinion etc. The problem 'Long term safe operation vs forced early closure' is discussed. It is concluded that the decision on early closure of any unit should be made on economic grounds or failure to meet regulatory safety standards and must not be politically motivated

  2. Prerequisites to promote energy efficiency investments in Bulgaria

    International Nuclear Information System (INIS)

    The PHARE Energy Programme's team observation and advice to the Committee of Energy in Bulgaria are outlined. In comparison to the Western European countries energy intensity in Bulgaria is 2-3 times higher. It is explained by the energy intensive industrial structure and the old and depreciated capital equipment. Cost-covering energy prices would make energy efficiency investment financially feasible and would attract financiers. But the lesson from Western European experience is that availability of finance capital and cost reflecting energy prices is not at all a necessary prerequisite for energy efficiency improvement. This improvement can be achieved with no cost or low cost measures. The potential for energy efficiency in industry (consuming more than 50% of the energy) is 11%-20%; in buildings - 6%; in transport - 4%. There are other obstacles, as lack of information, other business interests and no internal expertise, especially for small and medium size industries. The basic prerequisite to improve energy efficiency is raising of awareness and change of management culture, as well as radical change in organisational and management structures. (orig.)

  3. Geological formations in Bulgaria suitable for a deep HWL repository

    International Nuclear Information System (INIS)

    The total volume of vitrified high-level waste (HLW) and of intermediate-level wastes containing significant amounts of long-lived alpha emitters, generated over the lifetime of Kozloduy Nuclear Power Plant (NPP), is estimated to be about 2,100 m3. Selection of a suitable formation to host a deep HLW repository in Bulgaria presents serious difficulties owing to the small area of the country, its complex geology, and the expected negative reaction of the local population. After a preliminary categorization of the Bulgarian territory, more than 40 areas were identified initially as potential disposal sites. This number was reduced to 20 using a screening method. A large portion of the selected regions comprises thick (up to 1,000 m) Lower Cretaceous marls, some at a distance of 60-80 km to the south of Kozloduy NPP. There are no active faults in the vicinity of the chosen areas and the seismicity is of degree VII on the MSK scale. Several regions in south-east Bulgaria containing magmatic and metamorphic rocks, have been suggested as prospective sites for deep HLW disposal: the Byala Reka structure of Precambrian highly metamorphic gneisses, the Avren and Zalti Chal areas in meta-ultrabasites, the Sakar Palaeozoic granite pluton, and two areas in volcanogenic-sedimentary rocks. The possibility of subsea geological disposal has also been discussed. At present, a programme is being developed for more detailed investigations of the suitable geological formations. 20 refs

    Bulgaria totally banned the import, production and use of asbestos in 2005, but produced and used asbestos products during the last 3-4 decades of the 20th century. The aim of this study was to follow the incidence and mortality of mesothelioma in Bulgaria in relation to past occupational exposures. A literature search between 1960 and 2014 was conducted to obtain information on asbestos consumption, occupational exposure and asbestos-related diseases (ARDs). Data on registered mesotheliomas were provided by the National Cancer Register and data for recognized occupational ARDs were provided by the National Social Security Institute. An increase in the incidence of mesothelioma from 5 to 58 from 1993 to 2013, with 666 cases in the 21-year period, was registered. Incidence, mortality rates, deaths and male-to-female ratios and were lower in comparison to industrialized countries. The increase in mesothelioma incidence is considered as a consequence of more recent production and use of asbestos and asbestos products and the high occupational exposure between 1977 and 1989, while the lower rate of mesothelioma deaths and male-to-female ratio need to be investigated further.

    Investigations on the species composition and host range of aphids on ornamental greenhouse plants in Bulgaria was conducted over a period of five years, from 2008 to 2012. Twenty greenhouses, growing ornamentals for landscaping, plant collections and other purposes were observed. They were located in the regions of Sofia, Plovdiv, Smolyan, Pavlikeni, Varna and Burgas. The total number of collected aphid samples was 279. Their composition included 33 aphid species and one subspecies from 13 genera and 5 subfamilies. Twenty-eight species were found to belong to subfamily Aphidinae. Almost 70 % of all recorded species were polyphagous. The most widespread aphid species was Myzus persicae, detected in 13 greenhouses all year round, followed by Aulacorthum solani (10 greenhouses) and Aphis gossypii (9 greenhouses). The widest host range was shown by Myzus persicae (43 hosts), Aulacorthum solani (32 hosts) and Aulacorthum circumflexum (23 hosts). The list of host plants includes 114 species from 95 genera and 58 families. The greatest variety of aphid species was detected on Hibiscus (9 species). Out of all aphid samples 12.9 % were collected on Hibiscus and 6.8 %, on Dendranthema. The greatest variety of aphid species was detected on Hibiscus (9 species). Periphyllus californiensis and Aphis (Aphis) fabae mordvilkoi are reported for the first time for Bulgaria. Furthermore, Aphis spiraecola has been found in new localities and has widened its host range in this country. PMID:24039530

    In this work we analyze the development of a severe-convective-storm system in northwestern Bulgaria on 20 July 2011 which exhibited derecho-like characteristics. Prior to this event, a derecho had never been documented in Bulgaria. The convective system was associated with a cold front. We present a synoptic-scale analysis of the evolution of the cold front and an overview of the wind and the damage that has occurred in the region with the strongest impact. The convective system consisted of two multi-cell thunderstorms that are analyzed in some detail, based on radar data. The two storms merged and the convective system evolved into a bow-shape reflectivity structure with two rear inflow notches. The analysis of the radar data revealed cloud top heights of 17 km, with the formation of а bounded weak echo region, a maximum radar reflectivity factor of 63 dBZ, and wind speeds above 30 m/s. The field investigation revealed patterns in the damaged crops typical of strong wind gusts.

In the nuclear reactor operation the generation of radioactive waste (RAW) is an inevitable process. The waste must be conditioned, stored and disposed of in a safe manner. There are no national radioactive waste disposal facilities, for waste generated by an NPP, in Bulgaria to the moment. This situation necessitates the storage of operational RAW to be carried out on site for a long period of time (30 to 50 years). Following the principle for protection of human health and environment now and in the future, Kozloduy NPP adopted the concept for conditioning the RAW to a stable solid form and placing the waste in a package which should keep its features for a sufficiently long term so that the package can be safely transported to the disposal site.

  8. Total, accessible and reserve wind energy resources in Bulgaria

    International Nuclear Information System (INIS)

    The article is a part of the international project 'Bulgaria Country Study to Address Climate Change Inventory of the Greenhouse Gases Emission and Sinks Alternative Energy Balance and Technology Programs' sponsored by the Department of Energy, US. The 'total' average annual wind resources in Bulgaria determined on the basis wind velocity density for more than 100 meteorological stations are estimated on 125 000 TWh. For the whole territory the theoretical wind power potential is about 14200 GW. The 'accessible' wind resources are estimated on about 62000 TWh. The 'reserve' (or usable) wind resources are determined using 8 velocity intervals for WECS (Wind Energy Conversion Systems) operation, number and disposition of turbines, and the usable (3%) part of the territory. The annual reserve resources are estimated at about 21 - 33 TWh. The 'economically beneficial' wind resources (EBWR) are those part of the reserve resources which could be included in the country energy balance using specific technologies in specific time period. It is foreseen that at year 2010 the EBWR could reach 0.028 TWh. 7 refs., 2 tabs., 1 fig

    2012-06-01

    Full Text Available The pollen of the wild species from the genus Crocus L., spread in Bulgaria has been analyzed. The investigations, made by light microscope show that the pollen of these species is spherical in shape and round in outlines, comparatively big. These morphological characteristics of the pollen of the wild Bulgarian Crocuses define it as a primitive one [6]. The Scanning Electron Microscope investigations, made by Beug [1], established two types of pollen morphology. The results of our investigation led to the conclusion that the same types are also presented in Bulgarian species: – C.biflorus –type, or syncolpate and C.vernus – type, or inaperturate. Eight of the species belong to the first type and only C. pallasii belongs to the second. The pollen of C. reticulatus is with quite unclear aperture – maybe transition to the inaperturate type.

    The success of water management policies in our country is linked to the accuracy with which variations (temporal and special) in available water resources. Evapotranspiration is one of the most important processes in the land phase of the hydrological cycle. The aim of the presented paper is to estimate and describe the regime of the two river basins. Osam river base is representative for central part of Danube hilly plane and Struma river is the biggest river in south-western part of Bulgaria. The mean monthly potential evapotranspiration is calculated according Thornthwaite and Turc's empirical equations for mean monthly value actual evapotranspiration is applied. The long-term variability of evapotranspiration is analyzed.(Author)

  19. Contamination of soils in Bulgaria with Cs-137

    International Nuclear Information System (INIS)

    Cesium - 137 from the Latin word 'Caeius' - meaning sky blue or heavenly blue) is one of radioisotopes of cesium, which present in the biosphere in small amounts as a result of radiation leaks. It is an artificial radionuclide with a half-life of 30 years, and it was released into the nature by both stratospheric testing of above ground thermonuclear weapons and Chernobyl derived fallout. Cesium - 137 was deposited as fallout and in most environments was rapidly and strongly absorbed by soil particles at the ground surfaces. Its high affinity to fine soil particles, relatively long half-life, and world wide distribution have made it almost a universal environmental tracer. Definition of radiological state of soils in Bulgaria was done by using of nondestructive gamma-spectrometric analysis. Studying of concentration of cesium - 137 was made during the whole year at the specially marked stations at the territory of the country. Providing enough scientific data, scientists can define the real concentration of this radionuclide in soils. This is a very important process, because how we know soil is at the beginning of the food chain. So the good quality control here is very important. Cesium has no biological role. However it is capable of replacing potassium in the body to some extent because of its chemical similarity. Ingestion of any cesium compounds is therefore to be avoided. Because of its similarity the isotope 137CS is very toxic. In Bulgaria there were taken hundreds of samples per year, because of importance of this radioisotope and at the most cases the results are in normal borders. But the concentrations for the different parts of the country can vary from 0.2 Bq/kg to 540 Bq/kg. So it is necessary these parameters to be under control until its full stabilization and achievement of no biological and environmental risk.

  10. PROFILES AND PREFERENCES OF ON-LINE MILLENIAL SHOPPERS IN BULGARIA

    Directory of Open Access Journals (Sweden)

    Patricia R. Loubeau

    2014-05-01

    Full Text Available This research seeks to develop a better understanding of the factors affecting on-line purchasing behavior among Generation Y (Gen Y consumers in Bulgaria. Also called millenials and born between the mid-1970s and late 1990s, this generation is especially active on-line and will be a dominant influence shaping e-commerce. An empirical study was conducted based on a written survey of a sample consisting of 367 high school and university students in Bulgaria. The most important reason why Bulgarian young people shop on-line is the pursuit of unique products not locally available, followed by convenience and better pricing, and their favorite category of internet purchases is “Apparel and Accessories.” Bulgarian millennials are using the internet to shop for trendy fashion and to obtain a variety of brands that are unavailable locally. Like other regions of the world, concern about financial transactions security is a major barrier limiting the willingness to shop on-line in Bulgaria. Unlike other markets where on-line music purchases are growing, high levels of digital piracy in Bulgaria strongly discourage Bulgarian students from purchasing music on-line. One limitation of this study arises because of its reliance on a convenience sample of students from medium sized cities in Southern Bulgaria. Further research employing stratified random sampling across Bulgaria is needed to assess whether the findings are broadly generalizable for the Gen Y population.

    2014-01-01

    The aim of our study is to review the published literature on establishment and implementation of ISO 9001 QMS in European hospitals, to study the availability of International Organization for Standardization (ISO) quality management systems (QMS) in Bulgarian hospitals and to outline the main advantages of ISO implementation in the hospitals in Bulgaria. The information on availability of ISO QMS in the hospitals in Bulgaria was gathered via Bulgarian certification register, the registries of various quality associations, websites of hospitals and certification companies presented in Bulgaria. A total number of 312 hospitals in Bulgaria were screened for the availability of QMS certified against the ISO 9001 requirements. The experience of European hospitals that implemented QMS is positive and the used approaches to improve the processes and the demonstrated effects from ISO implementation are analysed by the researchers. Unlike other European Union member states, the establishment of quality management systems in Bulgaria is not compulsory. However, our study revealed that 14.42% of the hospitals in Bulgaria have implemented and have certified quality systems against the requirements of ISO 9001. Our study confirmed that a quality management system using the ISO 9001 standard is useful for the hospitals as it can help to increase the operational efficiencies, to reduce errors, improve patient safety and produce a more preventive approach instead of a reactive environment.

  12. Simulator training and human factor reliability in Kozloduy NPP, Bulgaria

    International Nuclear Information System (INIS)

    This is a PowerPoint presentation. Situated in North Bulgaria, in the vicinity of the town of Kozloduy, near the Danube River bank, there is the Bulgarian Kozloduy Nuclear Power plant operating four WWER-440 and two WWER-1000 units. Units 1 and 2 were commissioned in July, 1974 and November, 1975, respectively. These were shut down at the end of 2003. Units 3 and 4 were commissioned in December, 1980 and May, 1982. They were shut down at the end of 2006 as a precondition for Bulgaria's accession to the European Union. The 1000 MW units 5 and 6 of Kozloduy NPP were commissioned in September, 1988 and December, 1993, respectively. Large-scale modernization have been implemented and now the units meet all international safety standards. The paper describes the multifunctional simulator Kozloduy NPP for the operational staff training. The training stages are as follows: - Preparatory; -Theoretical studies; - Training at the Training Centre by means of technical devices; - Preparation and sitting for an exam before a Kozloduy NPP expert commission; - Simulator training ; - Preparation to obtain a permit for a license, corresponding to the position to begin work at the NPP; - Exams before the Nuclear Regulatory Agency (NRA) and licensing; - Shadow training at the working place; - Permission for unaided operation. The following positions are addressed by the simulator training: - Chief Plant Supervisor; - Shift Unit Supervisor; - Senior Reactor Operator; - Simulator Instructor; - Controller physicist; -Senior Turbine Operator; - Senior Operator of Turbine Feedwater Pumps of Kozloduy NPP. Improving of training method led to a reduction of number of significant events while worldwide practice proves that improvement of engineering resulted in an increase in the percentage of events, related to human factor. Analysis of human reliability in 2005 and 2006 in cooperation with representatives from Great Britain and the Technical University in Sofia were worked on the DTI NSP B

    The increasing incidence of Clostridium difficile infection (CDI) in Bulgaria has indicated the need to implement better surveillance approaches. The aim of the present work was to improve the current surveillance of CDI in Bulgaria by introducing innovative methods for identification and typing. One hundred and twenty stool samples obtained from 108 patients were studied over 4 years from which 32 C. difficile isolates were obtained. An innovative duplex EvaGreen real-time PCR assay based on simultaneous detection of the gluD and tcdB genes was developed for rapid C. difficile identification. Four toxigenic profiles were distinguished by PCR: A(+)B(+)CDT(-) (53.1 %, 17/32), A(-)B(+)CDT(-) (28.1 %, 9/32), A(+)B(+)CDT(+) (9.4 %, 3/32) and A(-)B(-)CDT(-) (9.4 %, 3/32). PCR ribotyping and multilocus variable number of tandem repeat analysis (MLVA7) were used for molecular characterization of the isolates. In total, nine distinct ribotypes were confirmed and the most prevalent for Bulgarian hospitals was 017 followed by 014/020, together accounting for 44 % of all isolates. Eighteen per cent of the isolates (6/32) did not match any of the 25 reference ribotypes available in this study. Twenty-four MLVA7 genotypes were detected among the clinical C. difficile isolates, distributed as follows: five for 017 ribotype, two for 014/020, 001, 002, 012 and 046 each, and one each for ribotypes 023, 070 and 078. The correlation between the typing methods was significant and allowed the identification of several clonal complexes. These results suggest that most C. difficile cases in the eight Bulgarian hospitals studied were associated with isolates belonging to the outbreak ribotypes 017 and 014/20, which are widely distributed in Europe. The real-time PCR protocol for simultaneous detection of gluD and tcdB proved to be very effective and improved C. difficile identification and confirmation of clinical C. difficile isolates.

    Full Text Available The present study aims to compare mineralogical composition of red soils, formed on marbles in South Bulgaria. We used mineralogical analysis of heavy and light mineral fraction in immersion under polarizing microscope and X-ray diffraction analysis of bulk sample and clay fraction. Three test polygons, located in South Bulgaria were examined: Petrovo, Nova Lovcha and Dobrostan, which are characterized with different latitude, altitude, and exposition. Three or more sites from each polygon were sampled and analyzed. The red soils are formed on white and gray calcite and calcite-dolomite marbles, impure silicate-rich marbles and only in one site – on marble breccias. We determined the following mineral phases in red soils: calcite, dolomite, quarts, and feldspars, mica, illite-type mica, illite, smectite, vermiculite-smectite, and kaolinite. Heavy minerals are represented by amphibole, titanite and epidote, and minor amounts of zircon, garnet, tourmaline, rutile, pyroxene, andalusite, kyanite, sillimanite and apatite. Opaque minerals are predominantly goethite and hematite. Plant tissue is abundant in light fraction from the uppermost soil horizons. Analyses of heavy mineral fraction show presence of metamorphic and igneous minerals which indicate participation of weathering products from other rock types in the nearby area. The types of heavy minerals in soils depend more on composition of parent rocks and geomorphic position than on climate type. Soils from Nova Lovcha show similar composition, but the quantity of goethite and hematite significantly increase in soil from plain. Typical high-metamorphic minerals as andalusite, kyanite and sillimanite present only in Nova Lovcha, while garnet dominates in Petrovo and opaque minerals - in Dobrostan. Red soils, formed on slopes, where erosion prevails over accumulation, contain more illite, smectite and vermiculite-smectite, and very few or no kaolinite, whereas the kaolinite is dominant in soils

    A study of the content of polonium-210 in a variety of foodstuffs produced in Bulgaria in 1970 revealed peak radionuclide concentration in wheat - 6.7 pCi/kg, followed by prunes - 2.2 pCi/kg, cabbage - 1.86 pCi/kg, peppers - 1.64 pCi/kg. The content of polonium-210 in onions, meat and potatoes was low (0.5, 0.8 and 0.9 pCi/kg accordingly). All other food products studied - milk, bread, beans, eggs, tomatoes, apples, pears, grapes and drinking water - appeared to have approximately equal polonium-210 concentration - from 1.21 to 1.35 pCi/kg. The daily intake of polonium-210 with food and water amounted accordingly to 1.61, 1.79 and 2.08 pCi/kg in preschool children, in school children and in senile individuals. The major part (68 - 82 per cent) of incorporated polonium-210 was eliminated with the stools. In all age groups the amount of polonium-210 removed daily from the body with the excreta corresponded to the intake, i.e. the balance of polonium-210 was in a state of equilibrium. The age factor in all three groups exerted no effect on the radionuclide intake and elimination from the body. (Ch.K.)

    Full Text Available In the conditions of the current economic downturn, many specialists consider tourism as one of the sectors with the greatest potential to provide worldwide economic growth and development. A growing tourism sector can contribute effectively to employment, increase national income, and can also make a decisive mark on the balance of payments. Thus, tourism can be an important driving force for growth and prosperity, especially in emerging economies, being a key element in reducing poverty and regional disparities. Despite its contribution to economic growth, tourism sector development can be undermined by a series of economic and legislative barriers that can affect the competitiveness of this sector. In this context, the World Economic Forum proposes, via the Tourism Competitiveness Index (TCI, in addition to a methodology to identify key factors that contribute to increasing tourism competitiveness, tools for analysis and evaluation of these factors. In this context, this paper aims to analyze the underlying determinants of TCI from the perspective of two directly competing states, Romania and Bulgaria in order to highlight the effects of communication on the competitiveness of the tourism sector. The purpose of this analysis is to provide some answers, especially in terms of communication strategies, which may explain the completely different performances of the two national economies in the tourism sector.

    Full Text Available Peanut is not listed as one of the major crops in the Bulgarian agricultural sector, but its economic and fi nancial viability is promising, but unknown. We use enterprise budgets, capital budgeting techniques, risk analysis and logistic regression models to examine the fi nancial and economic structure of peanut farms and to evaluate the factors infl uencing short and long-term profi tability. The results show that peanut production is a profi table venture for most peanut farmers in Bulgaria. Long-run analyses show that peanut production may be economically feasible and producers engaged in production for a period of seven years, and at a discount rate of 13%, may generate internal rates of return (IRR that vary from -20.57% to 67.39%. About 70% of the farms studied had IRRs greater than the discount rate. Sensitivity analyses show that profi tability of peanut production was infl uenced by yield and variable costs. There were risks at the village level associated with peanut production.

  19. FACTORS AFFECTING THE VEGETABLE FARMING EFFICIENCY IN BULGARIA

    Full Text Available The efficiency is the major economic category, which measures the final result and the expenses related to the production and provides value expression. The article aims to analyze the prospects and conditions for the development of field vegetable production in Bulgaria. Field vegetable farming is a traditional and fast developing sector of the Bulgarian agriculture. Its condition and development is determined by the various natural and geographic conditions in the country and the experience in cultivating and farming vegetable crops, which are traditional for the Bulgarian population. The vegetable farming is organized in individual private agricultural farms and agricultural farming cooperatives and is performed in small areas. The crisis in the vegetable farming raised a lot of questions that need to be answered. It is necessary to overcome the decrease in vegetable production. This can happen by establishing efficiently operating organizational companies. The most important reasons for the reported decrease are the result of the improperly conducted reforms in the agriculture industry as a result of which the economic condition of the sector is declining. A serious flaw is that the farmers are selecting certain crop production without conducting any preliminary marketing and without any signed contracts for produce realization.

  20. Pilot survey of patient dose from computed tomography in Bulgaria

    International Nuclear Information System (INIS)

    The number of computed tomography (CT) scanners in Bulgaria increased from 22 in 1996 to more than 160 in 2007. Big variety of scanners of different manufacturers and different generations exists in the country with predominant number of single-slice scanners. Significant part of the scanners is more than 10 years old. This work presents the pilot results from the measurements of CT dose quantities started in 2005 with the aim to spread them to a national survey of CT practice in the country. It was found that different clinical protocols are used for similar examination, resulting in large variations in dose quantities: CT air kerma index varied from 27.1 to 78.4 mGy for head examination, from 8.7 to 28.3 mGy for chest, 11.8 - 30.7 mGy for abdomen and 9.1 - 41.3 mGy for pelvis. The CT air kerma-length product for complete examination was found to vary from 310 to 1254 mGy.cm for head examination, from 215 to 893 mGy.cm for chest, from 265 to 615 mGy.cm for abdomen and from 220 to 761 mGy.cm for pelvis. The analysis demonstrated that the main reasons for found variations are differences in scanning geometry, beam quality, exposure parameters and scanning length. (author)

  1. Alternative energy balances for Bulgaria to mitigate climate change

    Christov, Christo

    1996-01-01

    Alternative energy balances aimed to mitigate greenhouse gas (GHG) emissions are developed as alternatives to the baseline energy balance. The section of mitigation options is based on the results of the GHG emission inventory for the 1987 1992 period. The energy sector is the main contributor to the total CO2 emissions of Bulgaria. Stationary combustion for heat and electricity production as well as direct end-use combustion amounts to 80% of the total emissions. The parts of the energy network that could have the biggest influence on GHG emission reduction are identified. The potential effects of the following mitigation measures are discussed: rehabilitation of the combustion facilities currently in operation; repowering to natural gas; reduction of losses in thermal and electrical transmission and distribution networks; penetration of new combustion technologies; tariff structure improvement; renewable sources for electricity and heat production; wasteheat utilization; and supply of households with natural gas to substitute for electricity in space heating and cooking. The total available and the achievable potentials are estimated and the implementation barriers are discussed.

    Crimean-Congo hemorrhagic fever (CCHF) is endemic in Bulgaria. During 2013-2014, 11 confirmed CCHF cases have been reported in the country (seven in 2013 and four in 2014). The present study provides the CCHF molecular epidemiology in Bulgaria based on all currently available S, M, and L RNA segment nucleotide sequences spanning the years 1978-2014. A relatively low genetic difference (0-6%, the maximum seen in the M RNA segment) was seen among the CCHFV sequences suggesting that a slow evolving CCHFV strain belonging to "Europe 1" clade is present in Bulgaria. Although the virus emerged in new foci during the recent years, it is more active in the established endemic foci which seem to offer the most suitable ecosystem and environment. Understanding the CCHF epidemiology and virus evolution is the basis for public health programs and vaccine design. J. Med. Virol. 88:769-773, 2016. © 2015 Wiley Periodicals, Inc. PMID:26455333

  3. Combating illicit trafficking of nuclear material and other radioactive sources in Republic of Bulgaria

    International Nuclear Information System (INIS)

    The turbulent history of the Republic of Bulgaria is proof of its importance for the commercial and military interests of the nations that have conquered and exploited the country through the ages. It is clear that it is the connecting node of two continents, Europe and Asia. It is a natural stop in the movement of goods for transcontinental commercial purposes as well as a natural resting place for the movement of armies during the ancient and medieval times. The geopolitical situation that currently exists in the Republic of Bulgaria may form conditions for illicit trafficking. This paper gives a short description of the efforts of the Government of Bulgaria to combat the illicit trafficking of nuclear material and other radioactive sources. (author)

    Bulgaria signed the Framework Convention on Climate Change at the UNCEP in Rio in June 1992. The parliament ratified the Convention in March 1995. In compliance with the commitments arising under the Convention, Bulgaria elaborates climate change polity. The underlying principles in this policy are Bulgaria to joint the international efforts towards solving climate change problems to the extent that is adequate to both the possibilities of national economy and the options to attract foreign investments. All policies and measures implemented should be as cost-effective as possible. The Bulgarian GHG emission profile reveals the energy sector as the most significant emission source and also as an area where the great potential for GHG emissions reduction exists. This potential could be achieved in many cases by relatively low cost or even no-cost options. Mitigation analysis incorporates options in energy demand and energy supply within the period 1992-2020.

    Establishment of topsoil magnetic database on a national scale provides important source of information, necessary for the purposes of soil classification; soil drainage; as an indirect estimate of the total soil carbon and initial planning in precision agriculture. Five hundred and ten topsoil samples from the upper 20cm of natural unpolluted soils from the territory of Bulgaria have been characterized by detailed magnetic measurements, including mass-specific magnetic susceptibility; frequency dependent magnetic susceptibility, Anhysteretic remanence, Isothermal remanence and their ratios; hysteresis parameters and ratios; as well as soil reaction (pH). Histograms of the measured parameters per soil type and for the whole database reveal specific peculiarities and dependence from different factors. According to the results from the factor analysis, 77% from the total variance can be explained by four factors. The main factor is dominated by the contribution from concentration-dependent magnetic parameters. The second factor reflects the role of fine-grained pedogenic magnetic fraction; while the third one is determined by the properties of the parent material. The fourth factor is governed by the effects from the internal structural peculiarities of the magnetic particles. The results from cluster analysis reveal the role of soil type and geology for the observed magnetic characteristics. The first two clusters separate soils, developed on volcanogenic/volcanic rocks and loess sediments. The third cluster is dominated by the soil type variable and includes mainly Cambisols, developed on different parent rocks. The fourth cluster separates soils developed on sedimentary rocks. The results emphasize the major role of geology (parent material) for the magnetic signature of topsoil samples on a national scale using sampling density of 1sample/200km2.

    Full Text Available We use a semantic differential based instrument to assess the main factors in demand attitudes of Bulgarian customers. We aim to find out whether specific marketing techniques could alter the demand for such a traditional product as the wine in Bulgaria. Given the fact that the Bulgarian customer only recently received the possibility to know them, we find that foreign wines are evaluated mainly with a prejudice of past knowledge, not linked to the actual product. We discover a rigidity in such prejudice and adhering to "standard" definitions of "prestige" and quality of wines. Most likely demanded in Bulgaria will continue to be mainly Bulgarian wines.

    Full Text Available Phytophthora is a genus of Oomycota responsible for some of the most serious diseases with great economic impact (Judelson and Blanco, 2005. While 54 species were found in the 20th century (Erwin and Ribeiro, 1996 another 51-54 new species have been identified(Brasier, 2008 since the year 2000. They are spread worldwide and have broad range of host plants – fruit trees, citrus, forest and park species. Phytophthora can cause serious damages in orchards and nurseries of apples, cherries, etc. In Bulgaria they have been found first on young apples and cherries (1998-1999 in Plovdiv region (Nakova, 2003. Surveys have been done for discovering disease symptoms in Plovdiv and Kjustendil regions. Isolates have been obtained from infected plant material (roots and stem bases applying baiting bioassay (green apples, variety Granny Smith and/or PARP 10 selective media. Phytophthora strains were identified based on standard morphology methods – types of colonies on PDA, CMA, V 8, type and size of sporangia, oogonia and antheridia, andoospores. Cardial temperatures for their growth were tested on CMA and PDA.For molecular studies, DNA was extracted from mycelium using the DNA extraction kit.DNA was amplified using universal primers ITS 6 and ITS 4. Amplification products concentrations were estimated by comparison with the standard DNA. Sequencing was done at the Scottish Crop Research Institute (SCRI, Dundee, Scotland. Phytophthora root and crown rot symptoms first appear in early spring. Infected trees show bud break delay, have small chlorotic leaves, and branches die all of a sudden. Later symptoms are found in August-September. Leaves of the infected trees show reddish discoloration and drop down. Both symptoms are connected with lesions (wet, necrotic in appearance at stem bases of the trees.Disease spread was 2-3% in most gardens, only in an apple orchard in Bjaga (Plovdiv region it was up to 8-10%.

  2. In search of a homogeneous nation: the assimilation of Bulgaria's Turkish minority, 1984-1985

    Directory of Open Access Journals (Sweden)

    Vesselin Dimitrov

    2000-01-01

    Full Text Available This article analyses the causes of the most extreme nationalist undertaking in Eastern Europe in the 1980s - the Bulgarian government's attempt to change the names of nearly one million Turks in the space of a few weeks in 1984-1985. The article argues that the assimilation campaign emerged as a result of a combination of threats and opportunities on a number of levels. Domestically, the failure of alternative strategies of dealing with the ethnic minorities created a temptation to resort to a radical solution, whilst the political and economic resources which the communist leadership commanded and which reached their high point in the mid-1980s gave it the means to undertake such a policy. Internationally, the Soviet Union, Bulgaria's main strategic ally, was powerful enough to protect it against possible Turkish and Western reprisals, but not strong enough to impose its own more tolerant nationalities policy on Bulgaria. Turkey, Bulgaria's historical enemy and the perceived patron of the Turkish minority, was seen as both posing a threat to Bulgaria after the invasion of Cyprus, and as suffering from weaknesses which would prevent it from undertaking serious counteractions. There thus existed in 1984-1985 a false 'window of opportunity' which encouraged the Bulgarian communist leadership to obliterate once and for all the problem of ethnic diversity with which they were increasingly unable to deal by other means.

  13. Forensic analysis of a smuggled HEU sample interdicted in Bulgaria

    International Nuclear Information System (INIS)

    Full text: A sample of HEU was seized in Rousse, Bulgaria on May 29, 1999, at a border crossing between Bulgaria and Romania. A search of the suspect's vehicle uncovered a lead canister hidden in the car trunk. The initial examination of the contents by Bulgarian scientists indicated that the sample was indeed HEU, and subsequently arrangements were made for a U.S. team of nuclear forensics scientists from several national laboratories to conduct a thorough examination. This report gives a summary of the results. The HEU sample was contained in a glass ampoule that was embedded in a yellow wax, and in turn the wax filled the inside of the cylindrical lead container. A broad set of techniques was used to examine both nuclear and non-nuclear materials. Our general experimental approach has been previously described at meetings of the Nuclear Smuggling International Technical Working Group (ITWG), but this case represents the application of the most diverse set of nuclear forensic measurements for an actual seized sample. Analysis of the HEU itself included particle characterization, stoichiometry, impurity elements, residual nuclides, age-dating, and U and Pu isotopics. Measurements by XRD, SEM, and TEM show that sample is mostly U3O8, with minor amounts of two other phases. The powder is extremely fine-grained (160 nm mean) and quite uniform in size. Most grains (95%) are equidimensional, with the remainder rod-or plate-shaped. The U is 72.7% U-235 with a high U-236 abundance of 12.1%. The sample is reprocessed, reactor-irradiated material. The original U enrichment was 90% and the irradiation burned up about 50% of the initial U-235. Pu is present at a very low-level (3 ppb); the Pu-239 abundance is 82% with 240/239=0.12. Three fission products were detected at low levels, giving unambiguous evidence of fuel recycling. The total impurity content is about 600 ppmw (mostly S, Cl, Fe, and Br), which we interpret as indicating a batch processing operation because the

    Full Text Available Purpose: This study analyzes the motivational factors for ISO 9001 certification in Bulgaria from the internal/external motivations perspective, or the so-called dual model.Design/methodology/approach: This study is based on a mixed method research approach, which employed two interviews with experts in the field of quality management at the exploratory stage, and a survey involving 127 companies at the descriptive stage.Findings: This study claims that enhanced company image and competitiveness – an external motivation - is the leading motivational factor for ISO 9001 certification in Bulgaria. At the same time, our primary investigation reveals that Bulgarian firms are not predominantly externally driven, for internal motivations including process improvement and product quality improvement seem to be an important driver for ISO 9001 certification. Last but not least, this research asserts that enhanced company image and competitiveness has a stronger impact on the motivations for ISO 9001 certification than customer and supplier pressure, which is in line with previous research works on developing economy economies such as Bulgaria. Finally, our study indicates a moderate, yet positive correlation between motivations for and benefits of ISO 9001 certification.Social implications: This research work casts some light on the evolution of quality management in Bulgaria since the end of communism, which can serve as an important foundation for the better understanding of quality management in former communist economies in general and Eastern European states in particular.Originality/value: Derived from the acute gap between ISO studies in Western and former communist economies, this research work presents one of the first official, international studies in the field of ISO certification in Bulgaria, and more precisely, a paper describing the motives for ISO 9001 certification among Bulgarian businesses.

  15. Does the genetic structure of spring snail Bythinella (Caenogastropoda, Truncatelloidea) in Bulgaria reflect geological history?

    Bythinella is a minute dioecious caenogastropod that inhabits springs in central and southern Europe. In the Balkans, previous studies have addressed its morphological and genetic differentiation within Greece and Romania while the Bulgarian species have remained poorly known. The aim of the present paper has been to expand the knowledge on the subject in Bulgaria. Shell morphology and anatomy of the reproductive organs were examined, and a fragment of the mitochondrial cytochrome oxidase subunit I (COI) gene and the nuclear ribosomal Internal Transcribed Spacer 1 (ITS-1) were sequenced from 15 populations. Additional sequences from eight previously studied populations were included in our analyses. Phylogenetic analyses revealed five main mitochondrial DNA clades, which were partly confirmed by analyses of the ITS-1 sequences. The genetic differentiation between the clades was found to be in the range p=2.4-11.8%. Most of the populations belonged to clade I, representing Bythinella hansboetersi, and were distributed in SW Bulgaria. Clades II and III inhabit areas adjacent to clade I and were most closely related with the latter clade. Much more distinct were clade V, found at one locality in NW Bulgaria, and clade IV, found at one locality in SE Bulgaria, close to the sea. Four populations were found in caves, but only one of these represented a distinct clade. Considering the observed pattern of interpopulation differentiation of Bythinella in Bulgaria, we can suppose that isolation between clades I, II and III may have been caused by glaciations during the Pleistocene. The time of isolation between the above three clades and clade IV coincides with the Messinian Salinity Crisis, and the time of isolation between the clade V and the other four most probably reflects the isolation of the Rhodopes from western Balkan Mts by the seawater of the Dacic Basin.

  16. Forensic analysis of smuggled high enriched uranium interdicted in Bulgaria

Measurements by XRD, SEM, and TEM show that sample is mostly U3O8, with minor amounts of two other phases. The U was 72.7% 235U with a high 236U abundance of 12.1%. The sample was reprocessed, reactor-irradiated material. The original U enrichment was 90% and the irradiation burned up about 50% of the initial 235U. Plutonium was present at a very low-level (3 ppb); the 239Pu abundance was 82% with 240/239=0.12. We determined the age of the chemical reprocessing by using seven nuclide systems. Using the multiple clocks enables us to evaluate the validity of the assumptions in the dating schemes. The slightly higher ages for Am and Ac chronometers are consistent with a Purex process. The mean age of the remaining clocks is October 30, 1993, with an uncertainty of only 25 days. The similar age for the Pu/Am clock suggests that the Pu is not from postprocessing contamination. The non-nuclear materials provide a number of forensic clues. Taken all together, the non-nuclear evidence is most consistent with assembly of the package in Eastern Europe from local sources. The nuclear isotopics can be used to constrain the type of reactor in which the HEU was irradiated. Detailed reactor calculations were performed using WIMS and GLASS codes for a pin fuel cell geometry. The results point to a light-water reactor with a very thermal spectrum. We calculate that a burn-up exposure of more than 300,000 MWD/MT are required

    Full Text Available Abstract Background Cardiovascular diseases are the major cause of death in Bulgaria. Because of notable differences in mortality rates between Bulgaria and other European countries, we presume a tangible difference in the management of acute myocardial infarction (AMI and an underutilization of evidence-based treatments. In order to determine the quality of care of patients with AMI in Bulgaria, we analyzed the appropriateness of current treatments and their relation to patient characteristics. Methods We performed a descriptive cross-sectional study, using retrospectively collected data from medical charts. We included all patients with AMI, residing and admitted to hospitals in the region of Stara Zagora, Bulgaria, between September 1st and December 31st, 2004. Socioeconomic status was surveyed within the framework of a structured patient interview. We used chi-square tests with Fisher's exact probabilities to analyze the relationship between prehospital time delay age, sex, and socio-economic status of the patients and Student's independent samples t-tests to check hypotheses about means. Results From 134 patients with AMI (mean age 64.6, SD 13.2, 66% male, 7% presented to a hospital within 59 minutes, and 44% within 4 hours of symptoms onset. The use of Heparin was 98%. In the first 24 hours, ASS was administrated in 82% and β-Blockers in 73% of the cases. At discharge Aspirin, β-Blockers, Angiotensin Converting Enzyme Inhibitors or AR-Blockers and Statins were used in 85%, 79%, 66%, and 43% of cases respectively. Intravenous fibrinolysis was applied in 32% of the eligible patients with ST-segment elevation. Percutaneous coronary interventions were applied in four patients within the first month after AMI. Hospital location in relation to a patient's place of residence and manner of transportation to hospital did not influence the time delay between the onset of symptoms to the start of hospital treatment.

    New results of moss survey 2000 of systematic study of air pollution with heavy metals and other toxic elements in Bulgaria are reported. The moss samples collected at 103 sites in Bulgaria, along the borders with Yugoslavia, Macedonia, Greece and Turkey were analyzed by instrumental activation analysis using epithermal neutrons (ENAA) at the IBR-2 pulsed fast reactor for a wide set of elements including heavy metals and rare earth elements (Na, Mg, Al, Cl, K, Ca, Sc, V, Cr, Mn, Fe, Co, Ni, Zn, As, Se, Br, Rb, Sr, Mo, Sb, I, Cs, Ba, La, Sm, Tb, Yb, Hf, Ta, W, Au, Th, and U). The results obtained are consistent with the mean European values for most of elements. The principle component analysis is applied to distinguish heavy and light crust elements and vegetation ones from those of anthropogenic origin.

  3. Probabilistic seismic hazard map for Bulgaria as a basis for a new building code

    Directory of Open Access Journals (Sweden)

    S. D. Simeonova

    2006-01-01

    Full Text Available A seismic hazard map proposed as part of a new building code for Bulgaria is presented here on basis of the recommendations in EUROCODE 8. Seismic source zones within an area of about 200 km around Bulgaria were constructed considering seismicity, neotectonic and geological development. The most time consuming work was to establish a homogeneous earthquake catalogue out of different catalogues. The probabilistic seismic hazard assessment in terms of intensities is performed following Cornell (1968 with the program EQRISK (see McGuire, 1976, modified by us for use of intensities. To cope with the irregular isoseismals of the Vrancea intermediate depth earthquakes a special attenuation factor is introduced (Ardeleanu et al., 2005, using detailed macroseismic maps of three major earthquakes. The final seismic hazard is the combination of both contributions, of zones with crustal earthquakes and of the Vrancea intermediate depth earthquakes zone. Calculations are done for recurrence periods of 95, 475 and 10 000 years.

  4. 'Mafia Baroque': post-socialist architecture and urban planning in Bulgaria.

    Holleran, Max

    2014-03-01

    This paper traces the reception of the architectural style known as 'Mafia Baroque' within the professions of architecture and urban planning in Bulgaria. The debate within these professions was strongly linked to the general decline of power among former intellectual elites and the specific decline of architects and planners, who were sidelined as arbiters of 'good taste' and disempowered as regulators of urban growth. The reaction to this style also highlights the rise in public concern over corruption and organized crime and dissatisfaction with post-socialist urbanization. This paper chronicles the extent of changes in construction and regulation in Bulgaria during the 1990s and argues that planners and architects were challenged not only by their professional marginalization but also by a deeper embarrassment over cultural change. It then relates this debate to broader post-socialist anxieties over insufficient regulation of urbanization and fear of failing to meet Western European goals for economic and political change.

    Among the many kinds of natural and man-made disasters, earthquakes dominate with regard to their social and economical impact on the urban environment. Global seismic hazard and vulnerability to earthquakes are steadily increasing as urbanization and development occupy more areas that are prone to effects of strong earthquakes. The assessment of the seismic hazard and risk is particularly important, because it provides valuable information for seismic safety and disaster mitigation, and it supports decision making for the benefit of society. Romania and Bulgaria, situated in the Balkan Region as a part of the Alpine-Himalayan seismic belt, are characterized by high seismicity, and are exposed to a high seismic risk. Over the centuries, both countries have experienced strong earthquakes. The cross-border region encompassing the northern Bulgaria and southern Romania is a territory prone to effects of strong earthquakes. The area is significantly affected by earthquakes occurred in both countries, on the one hand the events generated by the Vrancea intermediate-depth seismic source in Romania, and on the other hand by the crustal seismicity originated in the seismic sources: Shabla (SHB), Dulovo, Gorna Orjahovitza (GO) in Bulgaria. The Vrancea seismogenic zone of Romania is a very peculiar seismic source, often described as unique in the world, and it represents a major concern for most of the northern part of Bulgaria as well. In the present study the seismic hazard for Romania-Bulgaria cross-border region on the basis of integrated basic geo-datasets is assessed. The hazard results are obtained by applying two alternative approaches - probabilistic and deterministic. The MSK64 intensity (MSK64 scale is practically equal to the new EMS98) is used as output parameter for the hazard maps. We prefer to use here the macroseismic intensity instead of PGA, because it is directly related to the degree of damages and, moreover, the epicentral intensity is the original

    1994-06-01

    The restructuring of Bulgaria's social, economic and political system includes a change in the way it handles disaster preparation and response. During the Cold War, the entire country drilled regularly in civil defense, which was under the control of the army. A recent decree and pending legislation transfers civil defense from the military to the Council of Ministers, which has developed a national plan for defense against environmental hazards. This research shows that the transformation from command to market economy, plus the country's severe economic crisis, is degrading existing civil defense structures, preventing the implementation of the proposed new organization and increasing the population's vulnerability to hazards. Case studies of a small city, a petrochemical complex, coastal-zone hazards management, earthquake hazards regulation and the Kozloduy nuclear facility demonstrate Bulgaria's increasing vulnerability to environmental hazards.

    In July 2008, the Global Threat Reduction Initiative and the IRT 2000 research reactor in Sofia, Bulgaria, operated by the Institute for Nuclear Research and Nuclear Energy (INRNE), safely shipped 6.4 kilograms of Russian origin highly enriched uranium (HEU) spent nuclear fuel (SNF) to the Russian Federation. The shipment, which resulted in the removal of all HEU from Bulgaria, was conducted by truck, barge, and rail modes of transport across two transit countries before reaching the final destination at the Production Association Mayak facility in Chelyabinsk, Russia. This paper describes the work, equipment, organizations, and approvals that were required to complete the spent fuel shipment and provides lessons learned that might assist other research reactor operators with their own spent nuclear fuel shipments.

    Full Text Available The paper provides an extensive descriptive analysis and comparison of recent trends in union formation and fertility in Bulgaria and Russia. The analysis is based on data from the Generation and Gender Surveys (GGS carried out in 2004. We generate a large number of single- and multi-decrement life tables describing various life course events: leaving home and separation from the parental family, entry into union, first and second childbirth, divorce. Life tables are constructed for real cohorts as well as for synthetic cohorts. We study four real cohorts, born in 1940-44, 1950-54, 1960-64 and 1970-74. Synthetic-cohort life tables are constructed for three periods of time, referring to the pre-transitional demographic situation (1985-1989, the beginning of the transition (1990-1994 and recent demographic developments (1999-2003. We study also Roma and Turkish ethnic groups in Bulgaria. The life tables deliver detailed information that is otherwise unavailable. Our tentative findings indicate that societal transformation had a stronger impact on family-related behavior in the Bulgarian population than in the population of Russia. There is evidence that in some aspects Bulgaria is lagging behind other former socialist and Western European countries where the second demographic transition is more advanced. Evidence also suggests that Russia is lagging behind Bulgaria. However, certain specific features distinctive to Russia, such as the low level of childlessness, a drastic drop in second and subsequent births, and very high divorce rates even compared to Western European countries (it is a long-standing, not just recent trend, lead us to think that Russia may have a model of change particular to the country.

    Full Text Available The new EU member countries will participate actively in the growing freight development (Beckmann and Baum, 2002. The new EU member Bulgaria forms the ultimate frontier of the EU and because of its geographical location an important transit country for the transport between Europe and Asia. Because of numerous deficiencies in the Bulgarian transport infrastructure, the Bulgarian sections of the Trans-European road network cannot be used efficiently and thus Bulgaria loses large shares of the transit transport. To meet the challenges of the globalization and to benefit from the growing Euro-Asian logistics services in the future, the Bulgarian government has set the main objectives in the national transport policy in a master plan, which should be implemented by the year 2020. The aim of this study is to analyze the transport situation and the national strategic reference framework in the transport sector of the Eastern European EU member Bulgaria and based on the EU requirements for efficiency and sustainability of the European transport systems, to derive recommendations for the future development of the logistics systems in the accession country.

  19. Current status, surveillance and control of avian influenza in domestic and wild bird populations in Bulgaria

    International Nuclear Information System (INIS)

    This report describes the history and current status of avian influenza (AI) infection and control in Bulgaria. The country has a unique geographic position in Europe with regard to wild bird populations and their migration routes which pass through its territory. In recent years, Bulgaria did not remain free from AI. The region with the highest rate of isolation of H5N1 virus strains were the Black Sea coast and wet territories connected with the Via Pontica migration pathway in the administrative districts of Dobrich, Varna and Bourgas. Low pathogenic (LP) AI strains isolated from ducks were subtypes H3, H4 and H6 from the areas of Plovdiv, Pazardjik, St. Zagora, Yambol, Sliven and Haskovo. Raising ducks for liver production is a popular practice in south and southeast Bulgaria. From an epidemiological standpoint, controlling circulation of AI viruses among duck flocks, especially before their gathering in larger farms for fattening is a mandatory requirement of official authorities. To prevent the spread of highly pathogenic (HP) AI, surveillance of domestic poultry as well as wild birds should be strengthened in countries at risk, especially along bird migration routes. Monitoring, sampling and analysis of the viral subtypes of AI found in wild birds needs to be carried out to fully understand their role in the propagation and spread of HPAI viruses. (author)

    A detailed study of the Pernik (Bulgaria) seismic sequence of 2012 D.Solakov, S.Simeonova ,I. Georgiev, P.Raykova, L.Dimitrova and V.Protopopova National Institute of Geophysics, Geodesy and Geography-BAS, Sofia, Bulgaria The spatial and temporal clustering of aftershocks is the dominant non-random element of seismicity, so that when aftershocks are removed, the remaining activity can be modelled (as first approximation) as a Poisson process. The properties of aftershock sequences (distinct cluster, for example; even aftershocks can have aftershocks) allow time-dependent prediction of aftershock probabilities. Consideration of recent earthquake sequences suggests that aftershocks to large earthquakes although they are still, by definition, smaller events, can be very damaging and should be addressed in emergence planning scenarios. Because of the factors such as location and radiation pattern and the cumulative nature of building damage, aftershocks can cause more damage than the main shock. An earthquake of moment magnitude 5.6 hit Sofia seismic zone, on May 22nd, 2012. The earthquake occurred in the vicinity of Pernik city, at about 25 km south west of the city of Sofia (the capital of Bulgaria). The event was followed by intensive activity. The active area is situated in the central part of western Bulgaria. That is the most populated (more than 1.2 mil. inhabitants), industrial and cultural region of Bulgaria. Seismicity in the zone is related to the marginal neotectonic faults of Sofia graben. The boundaries of the graben are represented by SE-NW fault system with expressive neotectonic activity. This zone is characterized by shallow earthquakes. The strongest known event in the region is the 1858 quake with intensity I0=9-10 MSK. The 1858 earthquake caused heavy destruction in the city of Sofia and the appearance of thermal spring. It is worth mentioning that the seismic sequence of May 2912 occurred in an area characterized by a long quiescence (of 95 years

    2015-07-01

    Full Text Available Our study focuses on commercial banks which are operating in Bulgaria and Romania, two countries whose banking sectors have registered major structural changes in the transition to a market economy and which are showing some similarities. Similar to other EU countries, the financial system from Bulgaria and Romania is dominated by the banking sector, which holds the largest share of total assets. Thus, we can say that health, strength and performance of the banking sector are of major importance for the sustainable economic development of states, but also for efficient transmission of monetary policy decisions on the real economy. The paper aims to identify the key factors that affect bank profitability and to evaluate empirically their contribution to a sample of 29 commercial banks in Bulgaria and Romania, for the period 2003-2012. Our research is based on data from the Bureau Van Dijk database, the World Bank and the European Central Bank and uses panel data estimation techniques. The dependent variable used in our study is the bank profitability, which is measured by two representative indicators the Return on Average Assets (ROAA and Return on Average Equity (ROAE. Regarding the independent variables, our analysis includes capital adequacy, the loan loss reserve rate, cost to income ratio, the ratio of liquid assets to total assets, the interest expenses to deposits ratio, the non-interest income over total gross revenues, bank size, the GDP per capita growth, inflation rate, domestic bank credit to private sector and banking industry concentration. The results of our empirical study shows that among the variables considered, the loan loss reserve rate, the ratio of cost to income, GDP per capita growth and domestic bank credit to the private sector, have a significant impact on bank profitability, results in line with our expectations, but also with the results of other empirical studies.

  2. Advantages and Disadvantages of Fiscal Discipline in Bulgaria in Times of Crisis

    2014-03-01

    Full Text Available The global economic crisis of 2008 has posed serious challenges to the Bulgarian economy and was reflected in worsened macroeconomic indicators. The subsequent sovereign debt crisis in Europe further aggravated the situation and blocked its path to recovery. In line with the overall sentiment in the European Union (the EU, Bulgaria made maintaining fiscal stability a priority that it set out to accomplish by following a policy of austerity. The country managed to achieve the desired effect relatively quickly. It became one of the best performers in terms of budget deficit and government debt as a share of GDP (which are among the lowest in the EU. These accomplishments underlie international institutions’ greater confidence in Bulgaria, which has led to an increase in its credit rating. Nevertheless, the state has not managed to reap the maximum benefits that this type of policy offers. Fiscal sustainability was accomplished at the expense of economic growth, the slow pace of which was accompanied by impoverishment of the population, high unemployment, restricted consumption, and operational difficulties faced by real-sector companies. These problems fueled doubts about the adequacy of strict budget discipline, especially in times of crisis. They provoked the author to examine in greater depth the benefits and the drawbacks that such a policy ultimately offers to Bulgaria. The results show that the strict fiscal measures have put additional pressure on the already fragile economic growth and have a high social cost as well. All this justifies the need for the government to take on a new course to achieve economic recovery by means of more active state support that would stimulate a pickup in consumption and production activity.

    The soil radioecology is an important part of the environmental research in the country. Since the beginning of the 1970's regular monitoring of the content of different radionuclides in Bulgarian soils has been done. Objective of the studies were virgin soils from high mountain areas, hills and plains (the region of Kozloduy NPP and the Danube river valley). Natural and men-made radionuclides were observed. In the 25-year period after the the contamination with radionuclides due to the 1986 Chernobyl NPP accident a rich data base has been collected, recording the radiation status of the soils in Bulgaria. Special attention has been paid to the contamination with the long-lived technogenic radionuclides caesium-137 and strontium-90. This paper presents a summary of the obtained results. Caesium-137 and strontium-90 were the main men-made radionuclides detected in the examined Bulgarian soils few years after the Chernobyl NPP accident. Their content in the soils from high mountain areas (Rodopa and Rila mountains) is several times higher than that in the soils from North Bulgaria and Sofia fields. High non-homogenity in the pollution within small areas (even as small as several square meters) has been observed. Natural radioactivity was also studied. Averaged values for natural radionuclides like uranium-238, thorium-232, and radium-226 in virgin soils from different areas in the country are presented. A comparison of the dynamics of their behavior throughout the years is done. Bulgaria is a country with intensive uranium mining activities in the past years. That is why radiological monitoring of closed uranium mining facilities in different regions of the country are obligatory and of great interest. This work presents results from such investigations made in regions where remediation has been done. The results have been evaluated according to the Bulgarian radionuclide environment contamination legislation. The necessity of permanent environmental monitoring is

    Full Text Available Emerging Economies from Central and Eastern Europe take steps to ensure growth through tourism. Although they do not have the cultural, historical and artistic potential of the most famous tourist destinations, these economies promote forms of tourism for which they have suitable conditions. For example, Hungary is famous for health tourism, Bulgaria has made progress in terms of coastal tourism and Romania tries to make known the rural area although it has all conditions for practicing a wide diversified range of tourism forms. In this paper we present statistics showing how the tourism industry looks for three Central and Eastern European countries and we do a brief comparative analysis.

    Full Text Available This study presents the syntaxonomic diversity of the semi-natural grasslands in NorthEastern Bulgaria following the principles of the Ziirich-Montpellier School. A total number of 172 releves, collected during 2002-2004, is used. TWINSPAN clustering is applied for determination vegetation types. The diagnostic species groups for the associations and subassociations are created by Cocktail method using the phi-coefficient with values above 0.3 within the JUICE software. As a result class Fesluco-Brometea is established with the alliances Festucion valesiacae, Pimpinello-Thymion and Chrysopogoni-Danthonion. The originally described Botriochloetum ischaemi Pop 1977 association is considered as typical on the subassociation level and a part of our releves are referred to it. Following the nomenclature rules we determined the subassotiation typicum. One new subassociation named Thymefosum pannonici of more xerophytic character, as compared to typical one, and well represented by differential species is established. The geographical distribution of Agropyro-Thymetum zygoidi and Agrostideto-Chrysopogonetum grylli associations is extended to the territory of Bulgaria. Class Molinio-Arrhenalherefea is represented by Cynosurion alliance and Festuco-Agrostidetum association is established by its probably most eastern area of distribution.

  6. Regulatory aspects and activities in the field of radioactive waste management in Bulgaria

    International Nuclear Information System (INIS)

    Bulgaria uses nuclear power for electricity generation and for a variety of nuclear applications in industry, research and medicine. Six WWER type Nuclear Power Plants (NPPs) went into operation at Kozloduy between 1974 and 1991. Until 1988 spent fuel was transported back to the former Soviet Union, but since then has been stored on site. Operational low level waste is stored on site, but since 1993 a volume reduction strategy using supercompaction has been employed, which has reduced stored waste volumes by a factor of four. Institutional radioactive wastes are disposed at the Novi Han near surface repository, located 35 km from Sofia. It was commissioned in 1964 and is now about half full. Siting studies have begun for a new near surface repository that would accept both institutional and NPP waste. A legislative and regulatory framework, as well as organizational and institutional arrangements, are in place. A national strategy that includes provisions for compiling a national inventory of spent fuel and radioactive waste and provisions for funding spent fuel and radioactive waste management, has been developed. The paper elaborates on the current situation regarding radioactive waste management in Bulgaria. (author)

  7. FORECAST FOR THE DEVELOPMENT OF THE TOTAL ENERGY BALANCE IN BULGARIA TILL 2025

    Velkov, L.; Papazyan, M.; Kanchovsky, S.; Kanev, D.

    2007-07-01

    The paper comprises a long-term energy forecast for the Republic of Bulgaria in the prospective by the year 2025. This forecast aims to ensure a normal functioning of the national economy and meeting the energy demand in the households, while keeping in conformity with the environmental requirements. It evaluates the possibility and the necessity to decrease the energy dependency on foreign suppliers, without making any compromise concerning the security of supplies and the competitiveness of the national energy market. The forecast evaluates also which policy will permit for Bulgaria to fulfill the commitments undertaken as per the Kyoto Protocol and shows the role of the energy efficiency enhancement and the use of the RES potential, as well as the role of the development of a safe and reliable nuclear energy sector. The paper provides also a detailed analysis of the main trends in the development of the total energy balance of the country in the period 1997-2004, as it is considered that the trends, which appear in this period will have an important impact on the development of the energy sector in the next years.

  8. Forest-biological erosion control on coal-mine spoil banks in Bulgaria

    International Nuclear Information System (INIS)

    The forest fallowing of coal-mine spoils helps re-establish the processes of natural, self-sustaining, soil formation. Environmental monitoring in Bulgaria demonstrates that forestation can moderate soil pH (from ph> 3.0 to pH 1.3 g/cm3 in the 0-5 cm layer) in the case of coal briquette spoils at Pernik, near Sofia. Ground losses from forested, 16-17 degree slope, coal briquette-spoils at Pernik are a quarter of those from an entirely unvegetated section of the same embankment (48.5 vs 12. 1 mm in the period 1988-1994) despite the absence of ground cover beneath the trees. On lignite spoil banks, at Maritsa-Iztok, central Bulgaria, forestation increases the organic content of the soil to greater depths than revegetation with grass, and to a greater degree than conventional agricultural cultivation. On Pinus nigra forested crest sites at Pernik, and in Robinia pseudacacia forested groves on the lignite minespoil banks at Maritsa-Iztok, slopes showed ground advance rather than ground retreat. Slopes protected by mechanical means alone did not allow soil growth and, where the structure broke down, they suffered as much erosion as untreated sites. In sum, the forest fallowing of surface coal-mine disturbed land accelerates organic matter accumulation in the soil, helps improve soil structure, reduces erosion, and may transform soil loss into soil gain, even on steeply sloping sites. 17 refs., 3 figs., 1 tab

  9. Assessing the competitiveness of SMR with the INCAS model: the Bulgaria Case study

    International Nuclear Information System (INIS)

    An economic model (INCAS - Integrated model for the Competitiveness Assessment of SMRs) allows the comparison of the economic performance of SMRs (Small-to-Medium size modular Reactors) with that of Large Reactors (LRs). INCAS performs an investment project simulation and assessment of SMRs and LRs deployment scenarios. The paper aims at testing INCAS model evaluating the different scenarios of an undergoing project of next nuclear reactors in the Republic of Bulgaria. In Bulgaria the nuclear power is already present in the energy sector and the paper analyses the possible increase of energy production for 2,5 GWe of nuclear capacity. The country is represented through analysis of two main perspectives: characterization of Bulgarian energy sector with particular emphases on the nuclear power and analysis of the financial factors relevant to a new nuclear power plant construction. Comparative financial analysis are carried out for six alternative scenarios involving LR or SMR respectively. The results show that despite their small size, the SMRs succeed to overcome the disadvantages of the economies of scale they cannot profit from, and they demonstrate better performance in most of the quantitative indicators. A greater flexibility combined with auto-financing makes SMRs more able to offer better adjustment to the electricity demand growth at lower costs

  10. Plans for environmental restoration of uranium mining and milling sites in Bulgaria

    International Nuclear Information System (INIS)

    In 1992, uranium mining and milling industry in Bulgaria was closed down by Decree No. 163 of the Council of Ministers of the Republic of Bulgaria which defined the procedure for development of liquidation plans, their approval and the procedure for funding from the national budget. The 1994 Decree No. 56 of the Council of Ministers assigned the organization of the liquidation and rehabilitation activities to the Committee of Energy (later, in 1996, transformed to the Ministry of Energy and Energy Resources). An Interdepartmental Board of Experts including representatives of all concerned ministries and agencies was established to coordinate the above activities and to approve work plans. The main stages of liquidation of the uranium industry and its after-effects were defined as follows: (1) environmental status (maintenance of a minimized service mode in order to preserve the state of the site- environment system); (2) technical liquidation; (3) technical recultivation; (4) biological recultivation; (5) purification of contaminated waters; and (6) monitoring. In 1992 and 1993, preparation for the above activities was carried out by development of detailed preliminary studies and work plans for the first stage - the stage of technical liquidation. Their implementation was launched by evacuation of mining and drilling machinery, haulage and processing of finished products etc. (author)

    Full Text Available Botanical remains from sanctuaries and necropolises provide valuable information about ancient religious practices. The current paper discusses old and new archaeobotanical data from Bulgaria and the use of plants in ritual context from Antiquity. The time span of the 44 considered sites (sanctuaries and necropolises is between the 6th century BC and the 3rd century AD. Most of the sanctuaries in Bulgaria, where archaeobotanical remains have been studied, date to the Bronze and Iron Ages, and a large proportion represents the so called “pit fields”. Information concerning later periods is almost completely lacking. Some evidence on plant offerings is available from the necropolises of the Hellenistic and Roman periods. Although the archaeobotanical data from these sites are quite scarce, their increasing number allows the observation of some common tendencies. Cereals and pulses are most commonly identified at sanctuaries, while fruits are typical remains in the necropolises. Very often imported species (like stone pine, pistachio and olive are found which testifies to existing contacts with adjacent regions (mainly the Mediterranean area and North Africa.

    Full Text Available Introduction: In Bulgaria there are five medical universities: in the cities of Sofia, Plovdiv, Varna, Pleven and Stara Zagora. Their main mission is training specialists in the fields of medicine and health care, increasing their qualification by means of postgraduate education and performing research activities. One of medical universities’ top priorities is encouraging research activities mainly aimed at preparation and implementation of research projects. Aim: The purpose of our study is to examine the current status of research project activities in Bulgarian medical universities.Material and methods: In order to define the science competitions related to Bulgarian medical universities we have applied a documentary and sociological approach. Results: Research projects that Bulgarian medical universities can apply for are divided into two groups – national and international. The most significant international projects are European ones since Bulgaria is an EU member state and this allows us to participate in such projects. Conclusion: Universities should strive for establishing even better conditions for encouraging application for research projects aimed at developing competent and experienced staff, even though the majority of them may not obtain approval for financing.The changes in the situation regarding Bulgarian science require the implementation and development of more research staff motivated to improve their knowledge and skills in the relevant dynamically changing competition and project field.

  14. The abandoned undergound Cherno more coal mine (SE Bulgaria) - a source of low grade geothermal energy

    International Nuclear Information System (INIS)

    Flooded abandoned coal mines are a potential source of geothermal energy, which could be used for heating and cooling of energy efficient buildings. Cherno More Coal Mine is located in SE Bulgaria and has been closed for more than 20 years. It represents a large human-induced subsurface reservoir which consists of three interconnected coalfields (“Brigadir”, “9.IX.” and “Blagoev”). Their total volume of about 2.0x106 m3 has been calculated considering the size of the stone drifts. The mine water temperature is measured to be about 16°C in the only accessible vertical shaft (“9.IX.” coalfield). This is the first study of an abandoned coal mine in Bulgaria aiming at assessing its low-valued energy potential and evaluating the opportunity for heating and cooling buildings. The geological and hydrogeological characteristics of Cherno More Mine have been analyzed by using existing archive data and conducting additional chemical analysis of water samples and temperature measurements in the mine. The obtained data were used to develop a regional groundwater model of the area and a local hydrothermal model for a thermally-insulated furniture factory located in the vicinity of the vertical shaft. The simulated temperature distribution in the mine during exploitation showed no impact on the production temperature by reinjected water under defined steady state conditions, which created a reliable basis for mine water energy use

  15. Gas demand growth and trade in South-East Europe: What perspectives for Bulgaria?

    International Nuclear Information System (INIS)

    Gas demand and trade are said to grow in South-East Europe, and inter-regional gas transit is believed to gain importance. Despite a 5 to 10 year delay in economics and energy reforms compared to EU accession countries, prospects for economic recovery and a sustained growth of gas demand around 3.9%/year to 2020 in the region and 6.7% in Bulgaria appear real. Growth is contained by investment needs, vested interests in, and competition from, coal and nuclear as well as concerns about future gas prices, and import dependence. The densification of national and regional gas systems will proceed. Inter-regional (North-South and East-West) high-capacity gas pipeline will emerge as a tempting business perspective. While these perspectives are medium- and long-term, competition among pipeline projects is already waging at present. Bulgaria, Romania and Greece position themselves so as to safeguard future transit revenues, the latter country, in cooperation with Turkey, appearing to move fast with the support of the EU. A region wide optimisation of infrastructure projects appears desirable, however national strategic interests may conflict. (author)

    This paper presents some of the main technical features and insights of the Kozloduy nuclear power plant (NPP) units 5 and 6 probabilistic safety analysis (PSA) level 1. Probabilistic analyses and their applications in Bulgaria were given further impetus in recent years. More than 17 years after the first PSA study in Bulgaria in 1992 today probabilistic analyses receive increasing attention and application than ever before. The Bulgarian regulatory body (BNRA) is also interested in expanding their capability of reviewing and using PSA in plant safety assessments. In November 2008 within the framework of the program financed by European Union (PHARE), a project for assisting the BNRA in establishing the regulatory requirements on the base of PSA was completed. One of the objectives of this project was performance of the independent review of Kozloduy NPP units 5 and 6 PSA. This review was a new impulse for the authors to present in more details of Kozloduy NPP probabilistic assessment studies in the present paper.

    Due to the early decommissioning of four Water-Water Energy Reactors (WWER) 440-V230 reactors at the Nuclear Power Plant (NPP) near the city of Kozloduy in Bulgaria, large amounts of low and intermediate radioactive waste will arise much earlier than initially scheduled. In or-der to manage the radioactive waste from the early decommissioning, Bulgaria has intensified its efforts to provide a near surface disposal facility at Radiana with the required capacity. To this end, a project was launched and assigned in international competition to a German-Spanish consortium to provide the complete technical planning including the preparation of the Intermediate Safety Assessment Report. Preliminary results of operational and long-term safety show compliance with the Bulgarian regulatory requirements. The long-term calculations carried out for the Radiana site are also a good example of how analysis of safety assessment results can be used for iterative improvements of the assessment by pointing out uncertainties and areas of future investigations to reduce such uncertainties in regard to the potential radiological impact. The computer model used to estimate the long-term evolution of the future repository at Radiana predicted a maximum total annual dose for members of the critical group, which is carried to approximately 80 % by C-14 for a specific ingestion pathway. Based on this result and the outcome of the sensitivity analysis, existing uncertainties were evaluated and areas for reasonable future investigations to reduce these uncertainties were identified.

    Full text: Radiation-induced skin injury has been recognized for the past decade as a potential complication of fluoroscopically guided interventions (FGI). In our country the awareness of the possibility of appearance of skin injury as a consequence of FGIispoor. The number of interventional procedures is nearly 79 000 or 1.9% of all x-ray procedures performed in Bulgaria in 2013. There is a great probability patients to have radiation induced skin injuries but not to be diagnosed. This is the first report of two cases of radiation induced skin injuries in Bulgaria occurring in 2014. Case 1: 62-year-old man with chronic total occlusion (CTO), underwent two percutaneouscoronaryinterventions (PCIs) and one short coronary angiography (CA). The 2nd and the 3rd procedures were done the same day within one hour. Skin lesion of National Cancer Institute (NCI) toxicity grade of I was detected by the nurse 3 weeks after the last two procedures. The patient received total dose area product (DAP)> 56269 μGy.m2. Case 2: 76-year-old man, developed skin lesion of NCI skin toxicity grade IV about 11 months after a prolonged selective coronary arteriography by percutaneous right radial artery approach. It started with erythematous patch in the right side of the back 2 days after the procedure. The patient received DAP 86802 μGy.m2.

    Full Text Available Biocapacity of bacteria inhabiting karstic caves to produce valuable biologically active compounds is still slightly investigated. A total of 46 culturable heterotrophic bacteria were isolated under aerobic conditions from the Gallery with pre-historical drawings in Magura Cave, Bulgaria. Phylogenetic analysis revealed that most of bacterial isolates aff iliated with Proteobacteria (63%, followed by Actinobacteria (10.9%, Bacteroidetes (10.9%, and Firmicutes (6.5%. A strong domination of Gram-negative bacteria (total 81% belonging to nine genera: Serratia, Pseudomonas, Enterobacter, Sphingobacterium, Stenotrophomonas, Commamonas, Acinetobacter, Obesumbacterium, and Myroides, was observed. Gram-positive isolates were represented by the genera Bacillus, Arthrobacter, and Micrococcus. One isolate showed a signif icant phylogenetic distance to the closest neighbor and could represent а novel species. Heterotrophic bacterial isolates from Magura Cave were investigated for hydrolytic enzymes production, antimicrobial and hemolytic activity. Predominance of producers of protease (87%, followed by xanthan lyase (64%, lipase (40%, β-glycosidase (40%, and phytase (21% was observed. Over 75% of the isolates demonstrated antimicrobial and hemolytic activity. The results suggest that heterotrophic bacteria isolated from Magura Cave could be a valuable source of industrially relevant psychrotolerant enzymes and bioactive metabolites. This study is a f irst report on the taxonomic composition and biological activity of culturable bacteria inhabiting a cave in Bulgaria.

    International Nuclear Information System (INIS)

    Full text: An international team of senior nuclear safety and radiation protection experts today concluded a 12-day mission to review the regulatory framework for nuclear and radiation safety in Bulgaria. The Integrated Regulatory Review Service (IRRS) mission, conducted at the request of the Government of Bulgaria, identified a series of good practices and made recommendations to help enhance the overall performance of the regulatory system. IRRS missions, which were initiated in 2006, are peer reviews based on the IAEA Safety Standards; they are not inspections or audits. ''Bulgaria has a clear national policy and strategy for safety, which are well in line with international standards and practices and contribute to a high level of nuclear safety,'' said Mission Team Leader Marta Ziakova, Chairperson of the Nuclear Regulatory Authority of the Slovak Republic. The mission team, which conducted the review from 8 to 19 April, was made up of 16 senior regulatory experts from 16 nations, and six IAEA staff. ''The results of the IRRS mission will be valuable for the future development and reinforcement of the Bulgarian Nuclear Safety Agency (BNRA). The use of international standards and good practices helps to improve global harmonization in all areas of nuclear safety and radiation protection,'' said Sergey Tzotchev, Chairman of the BNRA. Among the main observations in its preliminary report, the IRRS mission team found that BNRA operates as an independent regulatory body and conducts its regulatory processes in an open and transparent manner. In line with the IAEA Action Plan on Nuclear Safety, the mission reviewed the regulatory implications for Bulgaria of the March 2011 accident at TEPCO's Fukushima Daiichi Nuclear Power Station in Japan. It found that the BNRA's response to the lessons learned from that accident was both prompt and effective. Strengths and good practices identified by the IRRS team include the following: A no-blame policy is enshrined in law for

  7. Exploring the effects of energy consumption on output per worker: A study of Albania, Bulgaria, Hungary and Romania

    International Nuclear Information System (INIS)

    In this article, we explore the long-run cointegration between output, capital and energy consumption, in per worker terms, for Albania, Bulgaria, Hungary and Romania. We use the augmented Solow (1956) model and the ARDL bounds procedure (Pesaran et al., 2001) to examine the short-run and long-run effects of energy and capital on output (in per worker terms). We also conduct causality test using the Toda and Yamamoto (1995) non-causality procedure. Our results show the existence of long-run cointegration between output per worker and energy per worker for all the four countries. We find that energy per worker have a dynamic short-run positive effect in Albania (0.37%), Bulgaria (0.25%), Hungary (0.36%) and Romania (0.68%), and a long-run positive effect in Bulgaria (0.32%) and Romania (0.63%) which duly indicate that energy consumption has a momentous long-run effect in these two countries. The causality results indicate a unidirectional causation from output per worker to energy per worker for all the four countries, and from capital per worker to energy per worker for Albania and Romania. Consequently, a balance between effective energy consumption and sound energy conservation policies are likely to support economic growth in the four countries. - Highlights: • Energy has a short-run positive effect in Albania, Bulgaria, Hungary and Romania. • A long-run positive elasticity is noted in Bulgaria and Romania. • Output per worker cause energy per worker in the four countries. • A unidirectional causality from capital to energy is noted for Albania and Romania

    Full Text Available A soil-vegetation-atmosphere transfer model coupled with a macroscale distributed hydrological model was used in order to simulate the water cycle for a large region in Bulgaria. To do so, an atmospheric forcing was built for two hydrological years (1 October 1995 to 30 September 1997, at an eight km resolution. It was based on the data available at the National Institute of Meteorology and Hydrology (NIMH of Bulgaria. Atmospheric parameters were carefully checked and interpolated with a high level of detail in space and time (3-h step. Comparing computed Penman evapotranspiration versus observed pan evaporation validated the quality of the implemented forcing. The impact of the human activities on the rivers (especially hydropower or irrigation was taken into account. Some improvements of the hydrometeorological model were made: for better simulation of summer riverflow, two additional reservoirs were added to simulate the slow component of the runoff. Those reservoirs were calibrated using the observed data of the 1st year, while the 2nd year was used for validation. 56 hydrologic stations and 12 dams were used for the model calibration while 41 rivergages were used for the validation of the model. The results compare well with the daily-observed discharges, with good results obtained over more than 25% of the rivergages. The simulated snow depth was compared to daily measurements at 174 stations and the evolution of the snow water equivalent was validated at 5 sites. The process of melting and refreezing of snow was found to be important on this region. The comparison of the normalized values of simulated versus measured soil moisture showed good correlation. The surface water budget shows large spatial variations due to the elevation influence on the precipitations, soil properties and vegetation variability. An inter annual difference was observed in the water cycle as the first year was more influenced by Mediterranean climate, while the

    The U.S. Geological Survey defined the Moesian Platform Composite Total Petroleum System and the Dysodile Schist-Tertiary Total Petroleum System, which contain three assessment units, in the Carpathian-Balkanian Basin Province of Romania and Bulgaria. The Moesian Platform Assessment Unit, contained within the Moesian Platform Composite Total Petroleum System, is composed of Mesozoic and Cenozoic rocks within the Moesian platform region of southern Romania and northern Bulgaria and also within the Birlad depression in the northeastern platform area. In Romania, hydrocarbon sources are identified as carbonate rocks and bituminous claystones within the Middle Devonian, Middle Jurassic, Lower Cretaceous, and Neogene stratigraphic sequences. In the Birlad depression, Neogene pelitic strata have the best potential for generating hydrocarbons. In Bulgaria, Middle and Upper Jurassic shales are the most probable hydrocarbon sources. The Romania Flysch Zone Assessment Unit in the Dysodile Schist-Tertiary Total Petroleum System encompasses three structural and paleogeographic subunits within the Pre-Carpathian Mountains region: (1) the Getic depression, a segment of the Carpathian foredeep; (2) the flysch zone of the eastern Carpathian Mountains (also called the Marginal Fold nappe); and (3) the Miocene zone (also called the Sub-Carpathian nappe). Source rocks are interpreted to be Oligocene dysodile schist and black claystone, along with Miocene black claystone and marls. Also part of the Dysodile Schist-Tertiary Total Petroleum System is the Romania Ploiesti Zone Assessment Unit, which includes a zone of diapir folds. This zone lies between the Rimnicu Sarat and Dinibovita valleys and between the folds of the inner Carpathian Mountains and the external flanks of the Carpathian foredeep. The Oligocene Dysodile Schist is considered the main hydrocarbon source rock and Neogene black marls and claystones are likely secondary sources; all are thought to be at their maximum

    In the case of accidental release of hazardous gases in the atmosphere, the emergency responders need a reliable and fast tool to assess the possible consequences and apply the optimal countermeasures. A number of models for the prediction and simulation of hazard areas affected by accidental releases of toxic gases are available worldwide. Modelling accidental releases may be required for a variety of reasons: for analyzing different accidental toxic release scenarios ("worst-case scenarios"), for preparing emergency response plans and optimal countermeasures as well as for real-time risk assessment and management (e.g. in the frame of the SEVESO directive). Depending on the demand and the particular purposes, the choice of the appropriate model is up to the authorities. The one year project was funded by the Austrian Science and research liaison Office (ASO, www.aso.zsi.at) as a part of the program: Research Cooperation and Networking between Austria, the public higher education institutions in Kosovo and South Eastern Europe. The project was conducted by the Central Institute for Meteorology and Geodynamics (ZAMG, http://www.zamg.ac.at) in cooperation with the University of Prishtina (Kosovo, www.uni-pr.edu and the National Institute of meteorology and Hydrology (NIHM Bulgaria, www.meteo.bg). One of the main purposes of the project was to provide the both partners with basic knowledge in modelling with accidental release of toxic gases, based on the practical experience of the meteorologists from the ZAMG in the area. This knowledge can be used as scientific response to society driven current or upcoming problems especially in Kosovo. The activities involved know-how transfer on European standards and practice among the project partners, as well as joint efforts to adapt and disseminate the scientific methods and results in Kosovo. Within the project, the partners from Kosovo and Bulgaria were introduced to the atmospheric dispersion model (ALOHA - Areal

    Full Text Available We examined peanut production systems and selected factors affecting the development of commercial peanut enterprises in Bulgaria. A survey of 220 individual farms and farm cooperatives engaged in the cultivation of peanuts was conducted during 2000 and 2002. Poor farm structure, low level of technology, and nonconformity to farm decision making impede the financial and economic development of Bulgarian peanut production and farm growth, thus limiting farm enterprises emergence into competitive economic units financially operative in a freemarket economy. The underlying cost structure, couple with small farms, averaging 0.8 ha in size, prevent farmers from capturing economies of scale, limit farm profitability and hence farm modernization. The lack of owned farm machinery, equipment and storage facilities renders the restructuring and specialization extremely difficult. However, peanut production is still a viable farm enterprise for Bulgarian farmers.

    The uranium deposits of Bulgaria related to the Late Alpine tectonomagmatic reactivation are subdivided into two groups: exogenic-epigenetic paleovalley deposits related to the basins filled with upper Eocene-lower Oligocene volcanic-sedimentary rocks and the hydrothermal deposits hosted in the coeval depressions. The geological and lithofacies conditions of their localization, the epigenetic alteration of rocks, mineralogy and geochemistry of uranium ore are exemplified in thoroughly studied paleovalley deposits of the Maritsa ore district. Argumentation of the genetic concepts providing insights into both sedimentation-diagenetic and exogenic-epigenetic mineralization with development of stratal oxidation zones is discussed. A new exfiltration model has been proposed to explain the origin of the aforementioned deposits on the basis of additional analysis with consideration of archival factual data and possible causes of specific ningyoite uranium ore composition.

Tomov’s research activity in that observatory is commented as well. The official opening of the observatory took place on July 21st, 1965. During the period 1966-1969 a monitoring program for determining the orbits of artificial satellites was successfully realized. Constructing a new building expanded later observatory. In mid-1969 the observatory was supplied by 60 cm reflector optical system ‘Cassegrain’, produced by Carl Zeiss in Germany; it was the biggest telescope in Bulgaria at that time. In the period 1970-1973 a modern single-channel photoelectric UBV photometer was constructed and put in operation. In 1976 the Belogradchik observatory joined with the Institute of Astronomy of the Bulgarian Academy of Sciences. In the second half of seventies and early eighties hundreds of galaxies were studied.

  18. Short-term forecasting of wind power installed in North-Eastern Bulgaria

    International Nuclear Information System (INIS)

    A large-scale introduction of wind power causes a number of challenges for electricity market and power system operators who will have to deal with the variability and uncertainty in wind power generation when making their scheduling and dispatch decisions. Wind power forecasting (WPF) is frequently identified as an important tool to address the variability and uncertainty in wind power and to more efficiently operate power systems with large wind power penetrations. Moreover, in a market environment, the wind power contribution to the generation portfolio becomes important in determining the daily and hourly prices, as variations in the estimated wind power will influence the clearing prices for both energy and operating reserves. In this report is presented the experience of national dispatching center of Bulgaria in short-term wind power forecasting. (author)

    International Nuclear Information System (INIS)

    SCORE stands for Supporting the Co-operative Organisation of Rational Energy Use. It aims at assisting the social transformation in the Central and Eastern European countries by creating self-supporting structures that are able to stimulate the efficient use of energy in end-user sectors. This document aims at presenting an in-depth institutional analysis of the energy efficiency situation in Bulgaria, including the current situation with regard to energy supply, consumption and environmental aspects, as well as an analysis of energy efficiency policies, instruments and organisations. Also, the document identifies problems related to energy efficiency in Bulgaria and indicates the areas of actions for an integrated SCORE programme in Bulgaria. The input for this process was provided by a survey among the main actors in the field, consisting of a questionnaire and interviews and a review of available information. The results were discussed in a workshop attended by the main stakeholders. The main characteristics of the Bulgarian energy sector are summarised in chapter 2. They indicate a high dependency on imported resources, a low quality of domestic fuels, a relatively high energy intensity of production and a low efficiency at supply and demand side with consider able potential for improvement. The restructuring of the sector has started but the process is far from completed. In the main towns heat is mainly supplied by district heating generated partly in co-generation plants. Gas distribution for public and residential buildings is quickly developing. In Chapter 3 the existing policies and actors are described and a 'roadmap' for energy efficiency actors is given. This provides the basis for defining the priorities for energy efficiency improvements presented in Chapter 4, by analysing the tools, policy instruments and organisations. Barriers and priority actions were defined in relation to the national policy level, the institutional structure, financial and

    International Nuclear Information System (INIS)

    The Coexistence Approach (CA) analysis was applied to plant macro- and microfossils from the Late Miocene to Early Pliocene sites in western Bulgaria to obtain quantitative climate data and reconstruct climate dynamics. Calculated new values for the Sofia macro flora confirmed a warm-temperate and humid climate with mean annual temperature (MAT) between 12–170C, mean temperature of the warmest month (WMT) 23.6–280C, mean temperature of the coldest month (CMT) 0–50C and mean annual precipitation (MAP) 843–1179 mm. This is consistent with the climatic parameters obtained from the microflora – MAT 13.6–16, WMT 23.6–27.9, CMT 3.7–6 and MAP 803–1308mm. All presented data are in good accordance with other regional palaeoclimate reconstructions from Bulgarian and Europaean floras. Key words: Late Miocene–Early Pliocene, palaeoclimate, Sofia Basin

    International Nuclear Information System (INIS)

    The final product of almost every usage of radioactive substances is a radioactive waste in some form: reprocessed nuclear fuel sources; radioactive solutions; materials which are contaminated by radioactive substances; by-products of biological tests and etc. All these substances are subject to temporary storage either till their radioactivity fully vanished and treated after that as a usual waste, or till their final collection for reprocessing and disposal in a final radioactive waste repository. The paper presented here deals with the Bulgarian organization for radioactive inspection of the registration and movement of the radioactive substances and their disposal as radioactive wastes in the country. It is important to note that the reprocessed nuclear fuel obtained from NPP ''Kozloduy'' is not kept on the territory of Republic of Bulgaria

  5. On the structural value of children and its implication on intended fertility in Bulgaria

    Directory of Open Access Journals (Sweden)

    Christoph Bühler

    2008-06-01

    Full Text Available Personal networks are receiving increasing recognition as structural determinants of fertility. However, the network perspective also helps to explain personal motivations for having children. Using theories of interpersonal exchange, social capital, and the value of children, it is argued in this article that children can substantively improve their parents' social networks. Individuals perceive this potential advantageous development as a structural benefit and consider this value in their reproductive decisions. This argument is empirically explored with data from Bulgaria, collected in 2002. The results document the presence of structural evaluations among subjectively perceived child-related benefits. Moreover, structural evaluations matter for the reproductive decision-making of Bulgarian citizens. Women's fertility intentions are supported by the prospect that a child will bring their parents and relatives closer or will improve their security at old age. Males' intentions are closely associated with the expectation that a child will provide support when they are old.

    International Nuclear Information System (INIS)

    Over a period of more than four decades, uranium deposits have been developed at many sites in Bulgaria and treated in two uranium ore plants in Bukhovo and Eleshnitsa. Quantitative determination of uranium, radium-226, thorium-232, polonium-210, lead-210, radon and radon daughters in samples of soil, water, vegetation, bottom sediments, fruits, vegetables and atmospheric air in the regions surrounding uranium mines and mills is performed by the National Centre of Radiobiology and Radiation Protection, Sofia (BG). Analyses of urinary and blood contents of natural radionuclides in the personnel and the population residing in these regions are performed. The number of radionuclides into the surrounding environment and their possible intake by man are analysed. The migration of some highly toxic long-lived radionuclides (mostly strontium-90 and cesium-137) generated from Kozloduy NPP is also studied. An assessment of their possible impacts on man is reported. (author)

  9. International perspectives on the importance of electric tariff transitioning to cost-based levels in Bulgaria

    International Nuclear Information System (INIS)

    The traditional cost-of-service approach to power pricing has been replaced in many countries by market pricing mechanisms that compensate power producers at the marginal cost of production established collectively in the marketplace. The paper stresses the importance of cost-based tariff setting pointing out two main pricing principles of utility services: 1) Revenues must meet or exceed the utility average cost of production; 2) Marginal cost pricing for incremental consumption must ensure efficient allocation of resources. Examples describing the factors encouraging transition to economically efficient tariffs at a small utility are given for: Northwest U.S., MINENERGO in Belarus, Pacific Gas and Electric Co in California and the National Electric Co (NEK) in Bulgaria.The analysis of the Bulgarian electric sector is based on ongoing work being funded by the U.S. Agency for International Development. Each of the four utilities described faces a different challenge for transitioning tariffs to cost- based levels. However, one and the same broad conclusion applies in all cases: utility pricing must take into account the underlying average and marginal cost structures of the regional power industry. Bulgaria needs transition to cost-based tariffs to recover the electricity cost-of-service and to ensure that the electric sector operates efficiently and consumers are treated fairly. Measures that facilitate the process of tariff transitioning include: 1) Developing a transparent process of tariff setting with clear objectives, a plan and timetable, and roles of organizations; 2) Establishing of independent regulation to ensure that tariff setting objectives are achieved; 3) Instituting mechanisms to reward organizations for performance that achieves electric sector objectives. 3 figs

  10. Study on variability of temperature and precipitation conditions in the South Eastern Bulgaria

    International Nuclear Information System (INIS)

    Freshwater resources are an essential component of the earth's hydrosphere and an indispensable part of all terrestrial ecosystems. The freshwater environment is characterized by the hydrological cycle. Global climate change and pollution could also have an impact on freshwater resources and their availability. There is now sufficient evidence, accepted by internationally respected scientists, that human activity is having an effect on the climate of the planet. The effects are mostly the result of greenhouse gas emissions, and are in addition to naturally occurring climate change. The impacts of climate change on water resources are displayed in every sector of water system. The temperature and precipitation are the most important factors, which affect on water resources. On the basis of meteorological data for more than 45 years from several gauging stations is made an analysis on the peculiarities of the climatic conditions in the southeastern Bulgaria. In order to trace the variability of historical precipitation and temperature series the analysis of trend and deviations from climate mean of recommended by WMO 'climate normal' period 1961-1990 was used. Precipitation over the southeastern Bulgaria has a significant variability over wide range of temporal and spatial scales. The annual precipitation data were examined for evidence of a secular trend by calculation of a linear best fit for the 1952 to 2000. The tendency of rainfall decrease was determined. The drought period in the studied region is noticeable during the summer. It should be concluded that temperature increase and precipitation decrease conduct to drought in the region and it may have more severe impacts on agriculture, water supply and society.(Author)

  11. New data on the paleocene section in Blateshnitsa Graben (Kraishte region, Western Bulgaria)

    International Nuclear Information System (INIS)

    Blateshnitsa Graben is superimposed upon a basement of allohtonous Palaeozoic anhimetamorphics and paraautohtonous Triassic and Jurassic sediments. According to the data from the Zemen borehole, the Graben is filled mainly by alluvial conglomerates and breccia conglomerates (in the lower part of the section) with rare interbeds, of sandstones, fine layered shales and three acid (to intermediate?) pyroclastic beds (in the upper part). K-Ar age of biotite crystalloclasts from the upper part (1.2 m) of the first pyroclastic bed was used to date the Blateshnitsa section. The data obtained (33.12 ± 1.50 Ma) indicate a Late Priabonian, Early Rupelian (or close to Priabonian - Rupelian boundary) age of the pyroclastic emission and accumulation. This first direct dating confirms the existing ideas on the age of Blateshnitsa Graben fill. The dated pyroclastics are transformed into zeolite rocks containing up to 35 % zeolite of heulandite type. They are formed at the expense of acid (to intermediate?) fine ash pumice fragments and glass shards, containing also a high amount (20-40 %) of crystalloclasts (mainly plagioclase and biotite, together with amphibole and quartz) and rare lithic fragments. The source of the pyroclastic component is under discussion. Redeposition of a loose fresh ash tephra by winds or current water is the most probable mechanism of its accumulation in fresh water Paleogene lake. It is supposed that the zeolitization took place in a hydrologically open system at shallow burial depths and in conditions, of humid and moderately warm climate. The Blateshnitsa zeolite rocks are a new find of such type of rocks for the territory of Bulgaria and the first Bulgarian occurrence formed in fresh water environment. Some problems on the Western Bulgaria Paleogene chrono- and lithostratigraphy are discussed. (Original)

The study was comprehensive for all premature children (N=58 and representative for full-term infants (N=192, or 10.4% of all of the 1827 full-term children born in 2007 at the University Hospital of Pleven and resident in the city of Pleven. Retrospective data on determinants under study were collected from all the mothers included in this study (N=250. Results: Mothers of premature children were more likely to be above 35 years old (27.6%, with a BMI ≥25 kg/m2 (23.1%, GWG below the recommended value (38.5% and to smoke during pregnancy (37.9%. The odds of being a smoker during pregnancy were five times higher among mothers with low birth weight (LBW newborns compared with their counterparts with normal birth weight newborns (OR=5.1, 95%CI=2.4-10.6. There was a positive association between BMI and LBW in infants whose mothers were overweight (OR=2.1, 95%CI=1.0-4.0. The risk of LBW increased when GWG was less than recommended (OR=1.8, 95%CI=1.0-3.1. Conclusion: Our results indicate that pre-pregnancy BMI ≥25 kg/m2, less than recommended GWG and smoking during pregnancy are risk factors for premature birth in Pleven region. Findings from this study suggest the need for active health and educational actions by health professionals in order to avoid premature births in Bulgaria.

    Full Text Available A soil-vegetation-atmosphere transfer model coupled with a macroscale distributed hydrological model was used to simulate the water cycle for a large region in Bulgaria. To do so, an atmospheric forcing was built for two hydrological years (1 October 1995 to 30 September 1997, at an eight km resolution. The impact of the human activities on the rivers (especially hydropower or irrigation was taken into account. An improvement of the hydrometeorological model was made: for better simulation of summer riverflow, two additional reservoirs were added to simulate the slow component of the runoff. Those reservoirs were calibrated using the observed data of the 1st year, while the 2nd year was used for validation. 56 hydrologic stations and 12 dams were used for the model calibration while 41 river gauges were used for the validation of the model. The results compare well with the daily-observed discharges, with good results obtained over more than 25% of the river gauges. The simulated snow depth was compared to daily measurements at 174 stations and the evolution of the snow water equivalent was validated at 5 sites. The process of melting and refreezing of snow was found to be important in this region. The comparison of the normalized values of simulated versus measured soil moisture showed good correlation. The surface water budget shows large spatial variations due to the elevation influence on the precipitation, soil properties and vegetation variability. An inter-annual difference was observed in the water cycle as the first year was more influenced by Mediterranean climate, while the second year was characterised by continental influence. The energy budget shows a dominating sensible heat component in summer, due to the fact that the water stress limits the evaporation. This study is a first step for the implementation of an operational hydrometeorological model that could be used for real time monitoring and forecasting of water budget

    Full Text Available We studied autumn-winter food (November-February, 1997-2003 of the Stone Marten in the Balkan Mountains, Central Bulgaria. A total of 26 stomachs (18 of males and eight of females were examined, of which contents was expressed as the number of occurrence and relative frequency of occurrence. The result clearly showed that rodents are primary prey for the Stone Marten. Birds and insects were the following categories consumed. The edible dormouse was detected as a prey for the first time in Bulgaria. Besides, wild ungulates and domestic animals were occasionally scavenged, while neither fruits nor artificial materials were detected in the marten stomachs. Thus, our study showed that the Stone Marten in the Balkan Mountains tended to be more carnivorous in winter.

    Full Text Available The topic of this volume is a result from The Contemporary City in Serbia and Bulgaria: Processes and Changes, a bilateral project of the Institute of Ethnography of the Serbian Academy of Sciences and Arts and the Institute of Ethnology and Folklore Studies with Ethnographic Museum of the Bulgarian Academy of Sciences (2014-2016. The six papers offer a comparative view of current social processes in two neighbouring Balkan countries, linked by numerous historical and political experiences. Comparative research into societal trends enables a more thorough understanding and monitoring of global processes. In today’s increasingly globalised and glocalised world, towns experience sudden changes and it is in the towns that these changes are most vividly to be seen. The focus of our research is on the dynamism of the contemporary town, on processuality and changes in societal practices. Ana Luleva examines life in the small town of Nessebar in southeast Bulgaria, which has been on the UNESCO World Heritage list since 1983. The protection, management and presentation of Nessebar’s cultural heritage are highly complex issues, further complicated by the problem of collision with the interests of the inhabitants. The author analyses the relations between the various factors - the state administration, municipal authorities and the local population. Here the tourist industry, investment interests, corrupt institutions and civil society all play their part. Ivanka Petrova chose to research Belogradchik, a small town in northwest Bulgaria. Petrova investigates how local social and cultural resources are used in the work of a family tourist enterprise. The author looks for answers to questions such as: how its members identify with the town and its culture and how the work of the enterprise fits into the Belogradchik local context. At the focus of her paper are current societal practices: the local urban economy and the production of images and symbols

  4. The importance for Bulgaria of multilateral approaches to the back-end of the nuclear fuel cycle

    International Nuclear Information System (INIS)

    Bulgaria has a comparatively small nuclear program, but this provides a significant contribution of about 45% to the total electricity production in the country. There are 4 WWER units in operation at Kozloduy NPP and the national energy policy foresees construction of a further plant, Belene NPP. Further development of the nuclear option is dependent on the assurance of both fresh nuclear fuel supply and long-term management of spent fuel and high level waste. Because of the technical and economic challenges involved, international co-operation (bilateral and multilateral) in the back-end of the nuclear fuel cycle is a strategic issue of prime importance. This approach is very politically and socially sensitive at home and abroad and requires international consensus on the legal framework. For Bulgaria, as a producer of nuclear energy which relies on imported fresh nuclear fuel, an option of major interest is to seek a final solution for dealing with spent fuel in co-operation with the supplier of fresh fuel, i.e. Russia at present. But Bulgaria does not address only this option. In parallel, Kozloduy NPP is an organizational member of the international association ARIUS, established in 2002 in Baden, Switzerland. Thus the country also directly supports the mission of Arius, namely the promotion of concepts for safe, secure, economic and politically and socially acceptable regional and international storage and disposal of spent fuel and HLW. Bulgaria also participates directly in the SAPIERR project that was initiated by Arius under the 6 Framework Programme of the European Commission in order to study the concept of regional repositories to be shared by European partners. The range of Bulgarian waste management activities - including practical issues at the power plants, national studies on waste treatment, and involvement in the bilateral and multinational approaches described above - ensures that the country continues to maintain the necessary technical

At the same time, the agriculture is the only branch, as in home, so in world scale in which the made as well direct production spending and investing regenerating (or not) only in the frameworks to one vegetative season. In addition on this, development of the intensive farming without using the most advanced technologies such as irrigation, automation, selection - for obtaining stable cultivars and hybrids, permanent weather monitoring and agroclimatic zoning and integrated and biochemical protection to the cultures and plantations had not possible. Analysis of long-term meteorological data from different regions shows clear tendencies to warming and drying for the period of contemporary climate (1971-2000) as well in Bulgaria. Hydro-meteorological conditions in the country are worsened. The most entire estimate is made from the Intergovernmental Panel for Climate Change (IPCC) 2007. Most of authors proven that the last decades are really warmest for last century, even for the entire period of the most instrumental observations. The causes for global warming was long time debatable, but the last investigations prove it anthropogenetic derive.

    Nowadays the effect on climate changes on the population and environment caused by air pollutants at local and regional scale by pollution concentrations higher than allowed is undisputable. Main sources of gas releases are due to anthropogenic emissions caused by the economic and domestic activities of the inhabitants, and to less extent having natural origin. Complementary to pollutants emissions the local weather parameters such as temperature, precipitation, wind speed, clouds, atmospheric water vapor, and wind direction control the chemical reactions in the atmosphere. It should be noted that intrinsic property of the air pollution is its "transboundary-ness" and this is why the air quality (AQ) is not affecting the population of one single country only. This why the exchange of information concerning AQ at EU level is subject to well established legislation and one of EU flagship initiatives for standardization in data exchange, namely INSPIRE, has to cope with. It should be noted that although good reporting mechanism with regard to AQ is already established between EU member states national networks suffer from a serious disadvantage - they don't form a regular grid which is a prerequisite for verification of pollutants transport modeling. Alternative sources of information for AQ are the satellite observations (i.e. OMI, TOMS instruments) providing daily data for ones of the major contributors to air pollution such as O3, NOX and SO2. Those data form regular grids and are processed the same day of the acquisition so they could be used in verification of the outputs generated by numerical modeling of the AQ and pollution transfer. In this research we present results on multitemporal monitoring of several regional "hot spots" responsible for greenhouse gases emissions in Bulgaria with emphasis on satellite-based instruments. Other output from this study is a method for validation of the AQ forecasts and also providing feedback to the service that prepares

    The objective of this study was to determine some features of cystic echinococcosis among children and adolescents, such as epidemiology, diagnosis, organ localization, treatment, and social and environmental factors favoring transmission of the disease. The 18-year study period (1996-2013) includes officially registered primary cases treated surgically, and/or with drug therapy, and/or with the puncture, aspiration, injection, reaspiration technique. Organ localization of the cysts and the most common diagnostic procedures were studied from the patients' medical records. Groups of diseased and healthy children were surveyed to outline some of the environmental and social factors influencing morbidity. From 1996 to 2013, the average annual incidence of cystic echinococcosis in the country was 6.7 per 100,000, but with significant variations in the incidence between different age groups. The hydatid cysts in children aged 0 to 9 years may most frequently be found in the lungs, in contrast to patients from other age groups. Almost 90% of the affected children had sustained contact with dogs. At present, among the countries of the European Union, Bulgaria holds the highest incidence and prevalence of cystic echinococcosis. Childhood echinococcosis remains a serious health problem for the country. Therefore, the study of cystic echinococcosis in children has important epidemiological significance concerning the intensity of transmission. PMID:25864190

    Full Text Available Persistent organochlorine pollutants (POPs like polychlorinated biphenyls (PCBs and DDT residues (DDTs can still be a problem for the aquatic environment and the human health. PCBs and DDTs were determined in three freshwater fish species: common carp (Cyprinus carpio, catfish (Silurus glanis, pike-perch (Sander lucioperca and two marine fish: shad (Alosa pontica pontica and grey mullet (Mugil cephalus. The freshwater fish samples were collected from the Danube River and from Black Sea, Bulgaria in 2010. The POPs were analyzed in order to investigate the presence of PCBs and DDTs in fish species from Danube River and compared the results to the levels in marine fish species from Black Sea. The fifteen congeners of PCBs, p,p’-DDT and its two main metabolites p,p’-DDE and p,p’-DDD were determined by capillary gas chromatography system with mass spectrometry detection. DDTs were the predominant contaminants in investigated species, with the p,p’- DDE contributing to more than 67% to the total DDTs. In freshwater fish concentrations of DDTs were found from 19.2 to 30.3 ng/g ww and PCBs concentrations - from 6.2 to 12.6 ng/g ww. The highest levels of PCBs and DDTs were determined in shad. The levels of DDTs and PCBs were determined lower than those found in similar fish species from other aquatic ecosystems.

    Full Text Available The following paper presents the results of an analysis of the intensity of competition in the milk and milk products sector in Bulgaria. The analysis is performed by adapting the Porter’s five forces model and based on the specific features of the sector concerned. For this purpose the author accepts the industrial concept of interpretation of competition: two levels of consideration of the competition intensity are differentiated - product class as a whole and separate product categories. Although not going into greater depth, the study reports the need of deepening the analysis by individual product groups, price levels and specific segments. The author proposes a methodological framework by which an analysis of the intensity of competition is conducted. Due to volume limitations of the publication, the emphasis of the paper is on the intensity of competition between existing companies; the barriers to enter and exit the sector are also presented; substitute products are marked briefly. The remaining forces from the five forces model are marked without going into details.

    Full Text Available From the beginning of the 1970s until the last global financial and economic crisis in 2008-2009, neo-liberal ideas guided economic policy development. It is worth noting that the Central and Eastern European countries transformed their economies from centrally planned to а market type at the peak of the liberal policies. Bulgaria offers a particularly interesting example because the country encountered a very difficult transition from one extreme of an economic system organization to another. The paper considers the reforms in the Bulgarian banking sector during the transition period from a centrally planned to a market type economy (from 1989 onward through the implementation of neo-liberal policies. The development of the banking sector and its transformation is analyzed throughout the two main periods: before and after the transition. The latter is divided into two sub-periods (phases beginning with the early 1990s, followed by the financial and bank crisis in the country, the introduction of a currency board regime in 1997, and stabilization, and ending with the global crisis in 2008-2009. This article summarizes that during the transition period, a modern banking system was established to accumulate profit rather than to promote economic growth. Following a chronological order, the negative effects of the liberalization of the Bulgarian banking sector are specified: the exportation of ownership (and control upon banking system assets, unfair asset redistribution, the emergence of the local oligarchy, the weak protection of the taxpayers and others.

In terms of my technical background and my working experience in the field of licensing and environmental impact assessment during the decommissioning of Units 1 to 4 at Kozloduy Nuclear Power Plant (KNPP) in Bulgaria, I decided to present the strategy for decommissioning of Units 1 to 4 at KNPP which was selected and followed to achieve safe and effective decommissioning process. The selected strategy in each case must meet the legislative framework, to ensure safe management of spent fuel and radioactive waste, to provide adequate funding and to lead to positive socio-economic impact. The activities during the decommissioning generate large volume of waste. In order to minimize their costs and environmental impact it should be given a serious consideration to the choice, the development and the implementation of the most adequate process for treatment and the most appropriate measurement techniques. The licensing process of the decommissioning activities is extremely important and need to cope with all safety concerns and ensure optimal waste management. (authors)

    Full Text Available Bark beetles (Coleoptera: Curculionidae: Scolytinae belong to one of the most damaging groups of forest insects and the activity of their natural enemies –pathogens, parasitoids,parasites or predators suppressing their population density,is of great importance. Biodiversity of entomopathogenic fungi on bark beetles in Bulgaria has been investigated sporadically. The aim of this preliminary study was to find, identify and study morphological characteristics of fungal entomopathogens naturally-occurring in populations of three curculionid species – Ips sexdentatus Boern, Ips typographus (L. and Dryocoetes autographus (Ratz.. Dead pest adults were found under the bark of Pinus sylvestris and Picea abies trees collectedfrom forests in the Maleshevska and Vitosha Mountains. Fungal pathogens were isolated into pure cultures on SDAY (Sabouraud dextrose agar with yeast extract and were identified based on morphological characteristics both on the host and in a culture.Morphological characteristics of the isolates were studied by phenotypic methods. The fungal isolates obtained from dead adults of Ips sexdentatus, Ips typographus and D. autographus were found to belong to the species Beauveria bassiana (Bals. – Criv. Vuillemin,Beauveria brongniartii (Saccardo Petch and Isaria farinosa (Holmsk. Fries (anamorph Ascomycota, Sordariomycetes: Hypocreales, Cordycipitaceae. Morphological traits of the isolates are described.

    Full Text Available The current publication presents the results of a research on the food spectrum of young Imperial eagles (juvennes, immaturus (Aquilaheliaca, SAVIGNY, 1809 in South Bulgaria. Dispersal sites and temporary settlement areas were identified tracking two young eagles marked with radio-transmitters. The birds were tagged in 2007 by the team of Green Balkans Federation. The feeding and behaviour of over 20 young Imperial eagles was observed in a total of 6 regions, including vulture feeding sites. A total of 32 pellets were collected from the trees used by those birds for roosting. Thus the feeding spectrum of young imperial eagles in their roaming period just after fledgling was identified. A total of 13 feeding components, comprising 101 specimens were identified. These were mainly small mammals, dominated by *- (Microtus arvalis, P. - complex (n= 56 specimens, 55,45% and significant presence of House mouse (Mus musculus, L. – 18 specimens or 17,82 %. The observations prove the presence of carcass among the food items taken by the wintering eagles and the particular use of the existing artificial feeding sites for vultures. The study proves the food opportunism of the species.

    Full Text Available Ten micro dam sites were studied in Southern Bulgaria between 2005 and 2007. They were situated below 700 metres above sea level in the Upper Thracian Valley and the Sredna Gora mountain. All the bank perimeters, totaling 24.72 kilometres, were walked searching for otter spraint sites. Most of them were found in the area around the river inflow (n=53, 40.5% followed by those near the wall of the dam (n=39, 29.8%. The other spraint sites were found in the two other zones of equal length in the middle part of the basins. The average levels of preference index showed the highest levels in the river inlet and dam wall zones. They were highest at the river inflow end, 1.6 (min-max=0.7–4.0 and a little lower near the wall, 1.2 (min-max=0.0–3.0. The middle zones of the basin were not so preferentially selected as spraint sites by otters, having index values about three times lower. We recommend otter monitoring at such basins to be focused on the areas close to the main river filling them.

    Full Text Available The Scotch thistle, Onopordum acanthium (Asteraceae has the Eurasian origin and represents an invasive weed in the USA and Australia. It is a serious problem in pastures,along roadsides, rangeland, etc. The weed is very common in Bulgaria and in 2009-2010several sites with large populations of O. acanthium have been located. The weekly surveys of some of the sites, mainly in the region of Plovdiv, revealed a significant diversity of phytophagous insect species, some of which had very high population density.More than 30 species have already been identified and observations on the phenology and biology of some of them have been conducted. For some of the species, such as endophagous Larinus latus, Lixus cardui, Eublemma amoena, Trichosirocalus briesei, or ectophagous Cassida rubiginosa etc. found during our surveys, there are reports in the literature describing them as having been already introduced as successful biocontrol agents in Australia. Endophagous species like lepidopteran Myelois circumvoluta and Pyroderces argyrogrammos which feed on the stems and the head, and the tephritid flies ephritis postica and Chaetostomella cylindrica which feed on the capitula, seem quite destructive for the weed, but need to be further studied regarding host specificity. Species like Vanessacardui and Brachycaudus cardui were found regularly, but in low population density, mainly due to the high rate of parasitism.

    Full Text Available From an agricultural point of view Bulgaria has insuffi cient and uncertain water resources. For the last decades, the potential vegetation period temperature sums submit to a positive tendency and the rainfall sums – to a negative one almost all over the country. This is evidence for the current drought processes determined by the global climate change. The increasing atmospheric drought impacts negatively water content in soil, especially that one available for plants. The paper deals with the impact of the contemporary climate changes upon the available soil water under winter wheat - one of the most important of our country crops for the food balance. The data processed have been gathered from 24 sites and refer to six soil types all over the agricultural territory. They cover the period of the “contemporary climate” (1961-2000. Actualized zoning of the soil water resources and maps of the changes in the availability of soil water have been elaborated. The results obtained allow development of adaptation farming strategies for management of the irrigation scheduling and maintaining of the other agricultural practices according to the climate changes. They will also be used for working out new standards for irrigation network design.

    International Nuclear Information System (INIS)

    Full text: The current analysis is designed to address concern about possible health effects in Bulgaria following the Chernobyl accident (CA). The results of descriptive studies are analyzed for the period 1981-1996 and 1981-2003 on malignant diseases of lymph and haemopoietic system and thyroid cancer (TC) respectively. Analyses of the risk of TC in consequence of CA for analytical studies are based on detailed thyroid gland's dose of exposure. Comparative investigations are based on number of patients with surgery operation. Discussed are the results of studies among children received prenatal radiation exposure at the time of the CA. Overall, in none of the studies doesn't prove a significant increase in the malignant diseases of the hemopoietic system incidence as well as in leukemia that could be attributed to the Chernobyl accident. No increase in the leukemia incidence among children was registered. The descriptive and analytical studies reviewed doesn't prove CA as a risk factor for TC incidence. The number of congenital anomalies did not show a statistically significant increase in relation to the nuclear accident. It doesn't prove any influence of CA upon development of the chosen children's groups learning abilities. Exposure of Bulgarian population after the Chernobyl accident is not a risk factor increased incidence rate in oncohematological diseases and TC in our country

    2011-12-01

    Full Text Available The aquatic macrophytes of lakes, situated in the whole territory of Bulgaria, were monitored during 2009. Six lake groups were established using differences in characteristics reflecting altitude, high calcium content and salinity, and altered hydromorphology and/or artificial origin. Abundance and species composition were assessed at each lake according to the requirements of the EU Water Framework Directive, using the assessment procedure of macrophyte-based assessment system, proposed by the Bavarian Environment Agency. The procedure included calculation of the ‘ecological quality ratio’ (EQR for each of 78 water bodies, based on transect monitoring data. For 31 of these lakes, a macrophyte assessment system was applied, for the remaining 47 lakes macrophyte quantity was insufficient or depopulation was assessed. Ecological status classification of lakes is based on the calculation of a Reference Index value. The Reference Index quantifies the deviation of species composition and abundance from reference conditions and classifies sites as one of the five possible ecological quality classes specified in the Directive. The EQR indicating Good and High (Maximum Ecological Status/Potential for macrophytes was achieved in 12 of the 31 lakes which fulfilled the criteria for assessment. The water quality parameters in lake types were discussed.

    Full Text Available Preliminary descriptions are given of selected specimens from an assemblage of >65 isolated vertebrate remains, collected in 1985 at the Labirinta cave situated between the villages of Drashan and Breste, east of Cherven Briag (Vratsa district, northwest Bulgaria, from strata of late Maastrichtian age (Kajlâka Formation. Recorded are a fragmentary lower jaw of a mosasaurine squamate, Mosasaurus cf. hoffmanni (MANTELL, 1829, with two teeth preserved in situ, as well as two isolated teeth of lamniform sharks, assigned to Squalicorax pristodontus (AGASSIZ, 1843 and Anomotodon sp. Other vertebrate remains in this assemblage include rather poorly preserved fragments of skull and appendicular skeleton of mosasaurs, but it cannot be ruled out that other vertebrate groups (elasmosaurid plesiosaurs are represented as well. To establish this, the additional material needs to be studied in detail and compared with existing collections; it will be described in full at a later date. A partial phragmocone of a scaphitid ammonite, found associated, is here assigned to Hoploscaphites constrictus (J. SOWERBY, 1817 and briefly described as well. This record dates the Labirinta cave sequence as Maastrichtian, as does the echinoid Hemipneustes striatoradiatus (LESKE 1778; tooth morphology of Squalicorax pristodontus and a find of the pachydiscid ammonite Anapachydiscus (Menuites cf. terminus WARD and KENNEDY 1993 from correlative strata nearby narrow this down to late, or even latest Maastrichtian. Finally, some remarks on mosasaur and plesiosaur distribution during the Campanian-Maastrichtian across Europe are added.

    Full Text Available This study is related to the investigation of the impact that vegetation caused on the avifauna of the parks “Lauta” and “Tsar Simeon Garden” located in the city of Plovdiv, Bulgaria. As a result of the study, we found that the biodiversity of the vegetation in park “Tsar Simeon Garden” is highly significant in comparison with the same in park “Lauta”. In the park “Tsar Simeon Garden” introduced plant species dominate over indigenous species, as compared with the park “Lauta”. The differences in the vegetation are caused by different management approaches carried out in the both parks. The degree of similarity between trees and bushes in both parks is low. The vegetation also had a significant influence on the avifauna living within the parks. The avian biodiversity in park “Lauta” is two times higher in comparison with the avian biodiversity in park “Tsar Simeon Garden”. The degree of similarity in the avifauna between both parks is significant, due the fact that all of the species, except one documented in “Tsar Simeon Garden” being documented in park “Lauta” as well. Eighteen new species of birds were recorded and described for the first time in the city of Plovdiv. The conservation status of the avifauna in park “Lauta” is quite significant in comparison with the same in park “Tsar Simeon Garden”.

    Full Text Available Fifteen years ago, Agenda 21, the United Nations' call to action for sustainable development, envisaged that the necessary harmonization and extension of existing policies and plans would occur through the adoption of an identifiable strategy for sustainable development. Since then, sustainable development is a widely used phrase and idea and it has many different meanings and therefore provokes many different responses. The aim of the article is to explore the role of the emerging South-Eastern administrations in the sustainable development under the changes and rules imposed by the European Union pressure. We will analyze both concepts, emerging administrations and sustainable development from the perspective of system theory and we will make the link with the concept of emergence, which is utilized to research and to analyze the nature of the changes in the public administration starting from the approach of the systemic theory. The research will be focused on the states form the south-eastern Europe, thus in the case study we will make a comparison between Romania and Bulgaria, as new member states of the European Union.

    Full Text Available Phytochemical screening of the content of total polyphenols, flavonoids, phenolic acids and anthocyanins in Bulgarian Carduus L. species was carried out. The plant materials (inflorescences from all of the 14 species found in Bulgaria has been collected from natural habitats from different floristic regions, during the period 2011-2013. Chemical analysis of the specimens was carried out in accordance with 11 Russian and 7 European Pharmacopoeia. For some of the plant species the obtained results are the first published data about content of phenolic compounds. The content of flavonoids (1,8-3,2% and total phenols(1,7-2,3% was higher in comparison with this of phenolic acids (0,6-2,4% and anthocyanins (0,5-1,5%. The highest content of total phenols and antocyanins was determined in the Carduus thracicus. The three species Carduus thoermeri, Carduus nutans and Carduus candicans ssp. globifer were characterized with the highest content of flavonoids. The highest content of phenolic acids was determined in the Carduus armatus.

    Two hundred Pseudomonas aeruginosa strains isolated in hospitals in Bulgaria were serotyped according to the combined scheme of Lányi and Bergan, supplemented by Akatova and Smirnova and Homma, using agglutinating O-antisera prepared in the National Institute of Hygiene, Budapest. The most frequently encountered serogroup is O2 (29%) followed by O11 (28.5%), O6, O3, O10 etc. The results were compared with those obtained by using Difco antisera prepared according to Liu et al., and showed 96.5% coincidence. The strains were phage typed according to the scheme of Meitert and tested for antibiotic resistance to aminoglycosides (gentamicin, carbenicillin, tobramycin and amikacin). Phage groups 3 (3a and 3(3)) and 1 (1a) predominated. The strains exhibited sensitivity to amikacin (99%) and frequent resistance to gentamicin (45.8%, carbenicillin (40%) and tobramycin (28%). Subdivision of the serogroups into phage and resisto-types contributes to analysis of nosocomial infections. PMID:3115050

    Full Text Available Aim: The purpose of this study was to reveal the seasonal distribution of emergency department visits of schizophrenic patients in Sofia, Bulgaria. Methods: We collected daily data for visits of patients with schizophrenia, schizotypal and delusional disorders in the emergency center of the regional dispenser for mental disorders in the city of Sofia for the period 1998-2003. The total number of emergency visits was 5723 (mean daily visits: 5.04±2.4. T-test was used to compare the monthly and seasonal distribution of visits. Results: The season with the highest levels of emergency visits was summer, and the lowest levels were observed in winter (P<0.0001. Spring and autumn had intermediate values close to the mean value, and significantly differentiated from winter values. The month with the highest admission rates was September, followed by May and the three summer’s months. The lowest levels were observed in December, October and January, with statistically significant differences observed between the values of all the three months. Differences between July values compared with December and October values were significant, but not with January values. Conclusion: The study showed significant seasonal and monthly differences in emergency schizophrenics’ visits. The data confirm the outcome of similar studies conducted in countries with temperate climate in the Northern Hemisphere. These results could prove useful for psychiatrists, public health specialists, and governmental authorities dealing with team planning and prevention programs in the field of psychiatry.

    Full Text Available The paper focuses on the current state of research and knowledge about ‘Balkan flint’ (hereinafter BF and trajectories flowing from the BF problem to the bigger and increasingly complex problem of the Neolithization of the eastern Balkans. The emergence and consolidation of the BF problem within the research agenda of specialists working on Balkan prehistory is briefly traced, as well as the confusing and inconsistently repetitive use of the term BF leading to some ‘mythologisation’ of the topic.A particular section of the paper represents the thoughts of the author on the conceptual meaning of BF in the context of the Balkan Neolithization debate, because until now its role has not been fully appreciated and recognized. Several theories and scenarios of the emergence and spread of the Neolithic in present-day Bulgaria are reviewed through the evidence of the particular Early Neolithic flint toolkits consisting in representative (retouched blades made from BF and attributed to the diagnostic features of the Early Neolithic package/culture.

  16. European Citizenship and Youth in Bulgaria: A Qualitative Comparative Analysis between Bulgarians and Bulgarian Turks

    Full Text Available European citizenship is a new concept, which has evolved with the process of European integration. Starting from the younger generations, the EU seeks to establish a modern and innovative view of citizenship through three fundamental elements - rights, identity and participation - that could lead to new ways of conceiving the relationship of institutions-citizens and citizenscitizens. The idea of European citizenship tends to overcome the historical idea of national states and national identity. It does this by reinforcing its supranational nature and developing an attitude of tolerance towards diversity and human/minority rights. Thus, to verify the impact European citizenship has on the younger generation in Bulgaria, this research is based on an inter-ethnic sample of 30 interviews (16 Bulgarians, 14 Bulgarian Turks and applies a qualitative comparative analysis method. This research seeks to answer these two main questions: 1 How do young Bulgarians perceive the concept of EU citizenship? 2 How do young Bulgarians perceive the new European citizenship in regard to the inter-ethnic relations in their own country? The study suggests that the EU’s attempt to promote European citizenship is underachieving. On the one hand, young Bulgarian people tend to be well exposed to European citizenship, irrespective of their ethnic belonging. On the other hand, the majority of them are sceptical of the tangible value of European citizenship for the reinforcement of a more encompassing and shared notion of diversity and minority rights.

  17. Quality control of nuclear medicine equipment in Bulgaria - present status and perspectives

    International Nuclear Information System (INIS)

    Full text: After long preparation period a regular quality control (QC) of nuclear medicine equipment is on the way to be implemented as a part of quality assurance in nuclear medicine. First steps in that direction were initiated by the Nuclear Regulatory Agency in 2003 with the requirement for mandatory acceptance testing after installation of gamma cameras - new and second hand. Later on the Ministry of health care (MH) approved medical standard 'Nuclear medicine', issued Ordinance No.30 for protection of individuals during irradiation for medical treatment and diagnostic. In January 2006 with written order of Ministry of health care a Commission for quality assurance in Nuclear medicine was appointed. All aforementioned documents explicitly regulate all aspects of QA in nuclear medicine. We present our experience in implementation of QC procedures for NMA, problems encountered, the apparent advantage of that activity, as well as the gaps, which has to be removed or corrected. A global view of current status of NMA in Bulgaria is presented and measures for improvement are suggested

    Full Text Available The aim of this study was to investigate the integral indicator for developmental stability, the fluctuating asymmetry (FA, in the marsh frog Pelophylax ridibundus populations that inhabit biotopes of different types (running rivers and still, dam lakes, when exposed to different types of anthropogenic pollution (domestic sewage pollution and heavy metal pollution in south Bulgaria. A total of 920 P. ridibundus individuals were used for FA analyses over three years (2009-2011. Fluctuating asymmetry was defined by 10 morphological traits, using the index frequency of asymmetric manifestation of an individual (FAMI. In closed water basins, regardless of the nature of toxicants, the FA values in P. ridibundus populations were statistically lower than those in river populations. The FA values were constantly the highest under conditions of sustained anthropogenic pollution, with high concentrations of toxicants in rivers with domestic sewage pollution and heavy-metal pollution. The results provide better opportunities to use FA in P. ridibundus populations for bioindication and biomonitoring, and for parallel and independent analyses of the physicochemical assessment of the environmental condition.

    Parvoviruses represent the most important infectious agents that are responsible for severe to fatal disease in carnivores. This study reports the results of a 10-year molecular survey conducted on carnivores in Bulgaria (n = 344), including 262 dogs and 19 cats with gastroenteritis, and 57 hunted wild carnivores. Real-time polymerase chain reaction (qPCR), followed by virus characterization by minor groove binder (MGB) probe assays, detected 216 parvovirus positive dogs with a predominance of canine parvovirus type 2a (CPV-2a, 79.17%) over CPV-2b (18.52%) and CPV-2c (2.31%). Rottweilers and German shepherds were the most frequent breeds among CPV-positive pedigree dogs (n = 96). Eighteen cats were found to shed parvoviruses in their faeces, with most strains being characterized as FPLV (n = 17), although a single specimen tested positive for CPV-2a. Only two wild carnivores were parvovirus positive, a wolf (Canis lupus) and a red fox (Vulpes vulpes), both being infected by CPV-2a strains. PMID:25382194

    Measles re-emerged in a nationwide outbreak in Bulgaria from 2009 to 2011 despite reported high vaccination coverage at national level. This followed an eight-year period since the last indigenous cases of measles were detected. The Bulgarian National Centre of Infectious and Parasitic Diseases collated measles surveillance data for 2009-2011. We analysed data for age group, sex, ethnicity, diagnosis confirmation, vaccination, hospitalisation, disease complications, and death and describe the outbreak control measures taken. The outbreak started in April 2009 following an importation of measles virus and affected 24,364 persons, predominantly Roma. Most cases (73%) were among children children 1-14 years old, 22% (n = 1,769) were unvaccinated and 70% (n = 5,518) had received one dose of a measles-containing vaccine. Twenty-four measles-related deaths were reported. The Roma ethnic group was particularly susceptible to measles. The magnitude of the outbreak resulted primarily from the accumulation of susceptible children over time. This outbreak serves as a reminder that both high vaccination coverage and closing of immunity gaps across all sections of the population are crucial to reach the goal of measles elimination.

  1. Impacts of climate variability on the runoff in the South Eastern part of Bulgaria

    International Nuclear Information System (INIS)

    The basic climatic factors, which affect the river runoff, are atmospheric precipitation and temperature. On the basis of the set of data from some hydro-meteorological gauging stations with more than 45 years observations have been studied the effect of meteorological conditions on runoff in the southeastern region of Bulgaria. The change of the temperature, precipitation and runoff over the southeastern Bulgarian catchments are investigated and analyzed. During the application of several statistical tests was found that there are changes in the runoff, which are not caused by the man's activity. The features in the variations of above mentioned hydro-meteorological elements and their inherent trends are determined. The results of this study show that the runoff decreases considerably all over the studied region in the last years. An attempt to find a cause of the changes was done. The significant tendency to gradual reduction of runoff in the region is due to considerably decrease of the precipitation all over the Balkans. The study shows that high temperatures and low precipitation conduct to drought in the region and appears unsuitable conditions for the river runoff feeding and development of plants. (Author)

  2. Soil degradation by sulfuric acid disposition on uranium producing sites in south Bulgaria

    International Nuclear Information System (INIS)

    This study assesses the damage of soils caused by spills of sulfuric acid solutions used for in situ leaching of uranium at eight uranium producing (by open-cast method) sites (total area of approximately 220 ha) in the region of Momino-Rakovski (South Bulgaria). The upper soil layer is cinnamonic pseudopodzolic ( or Eutric Planosols by FAO Legend, 1974). The results of the investigation show that the sulfuric acid spills caused strong acidification of upper (0-20 cm) and subsurface (20-60 cm) soil horizons which is expressed as decreasing of pH (H2O) to 2.9-3.5 and increasing of exchangeable H+ and Al3+ to 18 and 32% from CEC. Acid degradation of soils is combined with reducing of organic matter content. The average concentration of the total heavy metal content in the upper soil horizon (in ppm) is: Cd=1.5; Cu=30; Pb=25; Zn=40 and U=8. No significant differences were detected between the upper and subsurface soil layers . The heavy metal concentration did not exceed the Bulgarian standards for heavy metals and uranium content of soils. But the coarse texture of the top soil layers, the lack of carbonates, The low CEC and strong acidity determine a low buffering capacity of the investigated soils and this can be considered as hazardous for plants. This indicates that a future soil monitoring should be carried out in the region together with measures for neutralizing of soil acidity

    Full Text Available Beneficial use of leisure time is extremely important as it helps to expand the horizons for intellectual growth, emotional experiences, and personal enrichment. The aim of this study is to establish the interests and needs for music in children’s leisure time. Music is very close to the emotional nature of children and therefore could stimulate and develop their mental and physical abilities. This report focuses on the place of music and art in students’ life and discusses how much of their free time is taken up with these pursuits. It also analyses the needs of such activities. Here the results from a study in which children between 9 to 17 years of age from Bulgaria and Hungary took part are presented. The type of musical activities preferred by the children in their leisure time and the correlation between the activities of choice and cultural differences are also studied. Understanding what music activities children favour in their leisure time is important because learning combined with the arts builds long lasting social skills and educates on tolerance, creativity and discipline. This combination when used in work with children, helps children to develop ability for better self-expression, building up confidence, concentration, integration in the group, developing imagination, recognizing the good and beautiful, and increases their chances for success in life.

    Full Text Available The aim of our study was to investigate the otter habitats, their conditions in the Rhodopes Mountains (Bulgaria and the effect on the otter distribution and population density. The investigation was carried out during the period 2004-2006.The continually used (core habitats were: 1. large high mountain dams combined with headstreams. These were all at altitudes above 1000 meters. The effect of ecotone between the two habitats (dams and headstreams ensures food supply, shelter and space throughout the year. The otter was found in all such dams in the Western Rhodopes: Golyam Beglik, Shiroka Polyana and Batak. When all the bankside of Golyam Beglik Dam (21.8 km was searched, only one possible resident female was found. On Batak Dam (30.0 km, there were three possible resident females and one adult male; 2. Medium sized rivers. The otter was found in all such rivers in the Rhodopes. On a stretch of Chaya River between Jugovsko Hanche and Asenovgrad Town (14.5 km, two possible resident females, one adult and one sub-adult male, were recorded. On the Parvenetzka River, there were 2 possible resident female otters per 24 river kilometres; 3. Large Dams with steep banks in the lower parts of the mountain. The otter was found at Dospat Dam; no data for the population density was estimated.Temporarily used habitats and bank vegetation associations were also assessed according to their usage by the otters in the area and their conservation status.

  5. Public hearings for EIAs in post-communist Bulgaria: do they work?

    International Nuclear Information System (INIS)

    The participatory practices required as part of the established systems of Environmental Impact Assessment (EIA) practiced in the United States, Canada, Western Europe as well as several international agencies are more recent to the countries of Eastern Europe. The most common official forum for citizen participation in EIAs is the public hearing, which can provide important benefits. However, public hearings have been criticized as exhibiting several problems that preclude meaningful citizen input. This research explores three cases of public hearings held for EIA projects in Bulgaria. It argues that the public participation process and the public hearing in particular share the same problems that have been observed in other countries (including the United States and Canada). At the same time, however, Bulgarian public hearings do provide important indirect benefits that can contribute to the capacity for democratic governance and an active civil society. In the face of substantial economic obstacles and dramatic governmental reforms the country has endured since the end of communism, forums such as the public hearing are important means to foster institutional restructuring of a newly democratized country

  6. Large scale screening of spatial heavy metal distribution on territory of Bulgaria using Populus nigra as monitor. Final report for the period 15 December 1994 - 14 December 1996

    International Nuclear Information System (INIS)

    Large scale screening of heavy and toxic metals in Bulgaria using Populus nigra (poplar) leaves as biomonitor was done. Samples collected on more than 130 sites, were analyzed by neutron activation analysis and atomic absorption spectrometry. Elements As, Au, Ba, Br, Ca, Cd, Ce, Co, Cr, Cs, Cu, Eu, Fe, Hg, K, La, Mn, Na, Ni, Pb, Rb, Sb, Sc, Sm, Sr, Th, and Zn were determined. On average, mean values obtained for most of elements, were comparable to the literature ones for terrestrial plants and similar to comparable studies in Europe. Within the area investigated, the highest concentrations were found near metallurgical facilities around Sofia, and some ''hot spots'' which increased values for several elements at some other locations. Cluster analysis on limited number of elements yielded four regions with different levels of pollution: (1) Sofia and Plovdiv areas (the most polluted); (2) southwestern Bulgaria, middle-northern Bulgaria, Varna and Stara Zagora areas; (3) middle Bulgaria and the Bourgass region; and (4) northeastern Bulgaria (the least polluted). Study done on poplar leaves from unpolluted area during a course of 7 years showed fairly constant content of elements during this period thus providing appropriateness of poplar leaves as a biomonitor.

    Full Text Available A border and related concepts of “abroad” and “a foreigner” are analyzed from the linguistic, semiotic and socio-cultural points of view with regard to the USSR (Russia –Bulgaria relations. In spite of being very close to, even regarded as the 16th republic of the USSR and imitating many Soviet ideas, Bulgaria was a foreign country. The reasons for that on the lingua-cultural data partly of biographical character are discussed in the paper. The border can be a synonym to the language barrier, which exists or does not exist between native speakers of Bulgarian and Russian. The new developments of mutual Russian-Bulgarian language communication on the Bulgaria seashore provide us new data of the symbolism of temporal and spatial borders.

    the origin and transmission history of the FMD outbreaks which occurred during 2011 in Burgas Province, Bulgaria, a country that had been previously FMD-free-without-vaccination since 1996. Nineteen full genome sequences (FGS) of FMD virus (FMDV) were generated and analysed, including eight representative...... identified in wild boar. The closest relative from outside of Bulgaria was a FMDV collected during 2010 in Bursa (Anatolia, Turkey). Within Bulgaria, two discrete genetic clusters were detected that corresponded to two episodes of outbreaks that occurred during January and March-April 2011. The number...... of nucleotide substitutions that were present between, and within, these separate clusters provided evidence that undetected FMDV infection had occurred. These conclusions are supported by laboratory data that subsequently identified three additional FMDV-infected livestock premises by serosurveillance, as well...

  10. Approaches in setting up a system for certification of the Medical Physicists in some European Countries - possibilities for application in Bulgaria

    International Nuclear Information System (INIS)

    In Europe there are different approaches for harmonization with the Medical Exposure Directive (MED) and the EFOMP recommendations concerning the medical physicists' certification. The two most appropriate types are: 1) Based on folder with evidences and 2) Based on continuous professional development (CPD) evidences assessed by credit points system. An example for certification type 1 is the Radiation Protection Advisers (RPA) certification made by RPA2000 in the UK, which is described in the report. The experience of the Netherlands, Germany, Switzerland, Austria and Belgium are also presented. The situation in Bulgaria is analysed and proposal for further improvement and harmonization with the EC and EFOMP are given. A conclusion is made efforts should be done for establishing of modern accreditation and registration scheme of the MP and MPE in Bulgaria. In Bulgaria there is an urgent need for education, training and official certification of new specialists in this field

    Full Text Available Gardening the City: Neighbourliness and Appropriation of the Common Spaces in BulgariaThe paper discusses the forms of public-private space division in a postcosialist Bulgarian city as everyday practices of inhabiting and appropriation of the common spaces in one neighborhood of Plovdiv. The anthropological research of the urban spaces includes a long term observation of the everyday practices in the city of socialism, the city in transition and the changed cities nowadays, following the line of the changing boundaries, distinction and expression of the public and private, common and individual.The cases of particular interest in my research are the forms of transgression of the physical borders and social boundaries as well as establishing new ones, according to the changing identities, social hierarchies, power relations, forms of social solidarity and networking and investment in social capital. The paper presents cases of blurring borders and boundaries as urban discourses – of the socialist city, the city in transition and the other – the city after 2007 when Bulgaria joined the EU. These cases are studied on the base of the everyday practices of urban gardening in common spaces – around block of flats, on the windowed balconies and small gardens (vegetable plots in the town outskirts. Uprawianie miasta: sąsiedzkość i zawłaszczanie przestrzeni wspólnej w BułgariiArtykuł omawia formy publiczno-prywatnego podziału przestrzeni w postsocjalistycznym mieście bułgarskim jako codzienne praktyki zamieszkiwania i zawłaszczania przestrzeni wspólnej na jednym z osiedli w Płowdiw.

    The important factors for the agrarian output in Bulgaria are only thermal and water probability. From the two factors the component related to soil moisture is more limited. As well water and temperatures probabilities in the agrarian output are estimated trough sums of temperatures and rainfalls or by derivatives indicators (most frequently named as coefficients or indices). The heat conditions and the heat resources are specified by the continuousness of the vegetative period. Duration of vegetative season is limited for each type of plant, between the spring and autumn steady pass of air temperature across the biological minimum. For the agricultural crops in Bulgaria the three biological minimums: in 5°C are taken for wheat and barley, oat, pea, lentil and sunflower; 10°C for corn, haricot, and soybean and in 15°C for the cotton, vegetables and other spring cultures). The cold and warm period duration are mutually related characteristics. The first period define number of days with the snow fall and days with the snow cover, that are in the basis in the formation of soil moisture reserves after the spring snow melt. Definition of the regions with temperature stress conditions during vegetative season is one of the most important parameters of agroclimatic conditions. The values indicating for the limitations are one or more periods from at least 10 consecutive days with maximal air temperature over 35 °С. More from the agricultures, character for the moderate continental climatic zone are developed normally under temperatures 25-28°С. Temperatures over 28°C are ballast slowing the growth and destroying plants due to the heat tension. The component, limiting in greatest degree growth, development and formation of yields from the agricultural crops are the conditions of moisturizing, present trough atmospheric and soil moisture. The most apparent indicator is the year sum of the rains or their sum by the periods with the average daily temperatures of

    Type 2 diabetes mellitus (T2DM) is a growing public health problem in Bulgaria. While individual and lifestyle determinants have been researched; till date there has been no study on environmental risks such as road traffic, noise, and air pollution. As a first step toward designing a large-scale population-based survey, we aimed at exploring the overall associations of prevalent T2DM with exposures to road traffic, noise, and air pollution. A total of 513 residents of Plovdiv city, Bulgaria were recruited. Individual data on self-reported doctor-diagnosed T2DM and confounding factors were linked to objective and self-rated exposure indicators. Logistic and log-link Poisson regressions were conducted. In the fully adjusted logistic models, T2DM was positively associated with exposures to L(den) 71-80 dB (odds ratio (OR) = 4.49, 95% confidence interval (CI): 1.38, 14.68), fine particulate matter (PM) 2.5 25.0-66.8 μg/m 3 (OR = 1.32, 95% CI: 0.28, 6.24), benzo alpha pyrene 6.0-14.02 ng/m 3 (OR = 1.76, 95% CI: 0.52, 5.98) and high road traffic (OR = 1.40, 95% CI: 0.48, 4.07). L(den) remained a significant risk factor in the: Poisson regression model. Other covariates with consistently high multivariate effects were age, gender, body mass index, family history of T2DM, subjective sleep disturbance, and especially bedroom location. We concluded that residential noise exposure might be associated with elevated risk of prevalent T2DM. The inferences made by this research and the lessons learned from its limitations could guide the designing of a longitudinal epidemiological survey in Bulgaria. PMID:27157686

  14. Cultural cross-border co-operation among Balkan's countries with the case of Serbia and Bulgaria

    Full Text Available Cultural cross-border cooperation includes all fields of cross-border cooperation and gives base for main connections and interactions. Without strengthening cultural cross-border cooperation, it is impossible to build significant relations between neighbors. Culture, as a foundation, an activator and a purpose of development in cross-border regions, represents a cardinal and conditional factor of cross-border cooperation. Today's situation in the Balkans reveals ethnic diversity of this region and territorial dispersion of ethnic groups. This implies at the same time great cultural diversity as well as dispersal of various national cultures over the Balkan's states. During the 20th century Serbia and Bulgaria have very complex political and intrastate relations. But in the last 10 years there have been significant improvements in the cross-border cooperation between Serbia and Bulgaria. The results of these improvements are established Euro-regions and implemented cross-border projects between these two countries. Existing Euro-regions between Serbia and Bulgaria created links between various local authorities and made excellent basis for cross-border initiatives and joint projects to promote common interests across the border and cooperation for the common good of the border areas populations. The well managed cultural cross-border cooperation between these two countries will provide a clear view of common features and raise common identity for the region, contribute to tolerance and understanding between people in this area and enable them to overcome the peripheral status of the border region in their countries and improve the living conditions of the population.

    Full Text Available Herein, correlations of the Jurassic sediments from NE Serbia with those of NW Bulgaria are made. The following Jurassic palaeogeographic units: the Eastern Getic, the Infra-Getic and the Moesian Platform are included in the study. The East Getic was studied in the outcrops near Rgotina, where the sedimentation started in the Hettangian and continued during the Callovian-Late Jurassic and is represented by platform carbonates. The Infra-Getic is documented by the sections of Dobra (Pesača and the allochtonous sediments near the Štubik. Very important for the Infra-Getic are the Late Jurassic volcano-sedimentary deposits of the Vratarnica Series, which crop out near Vratarnica Village. The Jurassic Moesian platform was studied in the sections near D. Milanovac and Novo Korito (Serbia and in their prolongation in NW Bulgaria into the Gornobelotintsi palaeograben. Very important are the correlation in the region of Vrška Čuka (Serbia and Vrashka Chuka (Bulgaria - Rabisha Village (Magura Cave. A revision of the Jurassic sediments on the Vidin palaeohorst, which were studied in the Belogradchik palaeohorst, Gorno-Belotintsi palaeograben, Belimel palaeohorst and the Mihaylovgrad palaeograben, is made. The sedimentation on the Vidin palaeohorst started during different parts of the Middle Jurassic, and in the Mihaylovgrad palaeograben during the Hettangian (Lower Jurassic where the sediments were deposited in relatively deeper water conditions. To south, the relatively shallow water sediments deposited on the Jurassic Vratsa palaeohorst on the southern board of the Mihaylovgrad palaeograben are described.

    The Dobrudzha Coalfield in northeast Bulgaria has coal-bearing deposits ranging from latest Namurian to early Stephanian age (late Bashkirian to Moscovian age). Palynology of the coals in the upper Makedonka, Krupen and Gurkovo formations has been used to identify major changes in the vegetation during late Westphalian and early Stephanian times. The palynomorphs were grouped in two different ways (according to general morphotype and according to parent plant group) and stratigraphical trends in the two sets of groups used to identify vegetation change through the succession. Detrended Correspondence Analysis was also used to identify ecological relationships between the palynofloras. In the upper Makedonka and Krupen formations, lycophyte spores mostly comprise 15-25 % of the palynofloras in the thicker seams, but in the thinner coals they can represent up to 55 %. Of the other plant groups, ferns are the most abundant, representing 31-69 % in the thicker seams, 12-41 % in the thinner seams. In the Gurkovo Formation coals, lycophytes form an even smaller part of the palynological spectra, usually less than 10 % and in only one sample just over 25 %; fern spores make up 43-57 % of the palynofloras. This is in contrast to the palynofloras reported from contemporaneous elastic deposits in South Wales, most of which consist mostly of 34-60 % lycophyte spores and 14-34 % fern spores. Even more marked is the difference from the contemporancous coals formed in lowland settings in the USA, which have mostly {gt} 50 % lycophyte spores. This evidence suggests that the timing of the decline in abundance of arborescent lycophytes varied according to elevation above sea-level. In lowland coastal settings, the lycophytes remained dominant until middle-late Cantabrian times, but in more inland areas they were progressively replaced mainly by arborescent ferns during late Westphalian times.

    An experiment was made with the Rumen Simulation Technique (Rusitec) in which the fermentation of a mixed ration of hay (12.8 g/d) and bruised barley (3.2 g/d) was compared with the fermentation of the same diet in the presence of 5 mg monensin/d from the USA, CSFR and Bulgaria. The fermentation of the mixed ration was significantly affected by all three kinds of monensin. The digestibility of dry matter (DM) in the rations declined in the presence of monensin from 48% to 40% (tab. I). The digestibility of detergent fibre, cellulose and hemicellulose also declined in the presence of monensin (tab. I). The production of methane decreased (-70%) and CO2 production dropped too, but this decrease could be accounted for by the changes in the production of volatile fatty acids and redistribution of metabolic hydrogen (tab. I). Monensin decreased the production of total volatile fatty acids (-21%), the production of acetic (-35%), n-butyric, n-valeric and isovaleric acids (tab. II) and increased the production of propionic acid (+60%). The production, utilization and recovery of metabolic hydrogen were significantly increased in the presence of all three kinds of monensin (tab. IV). The end products of fermentation were affected by an addition of monensin to the mixed ration. All three kinds of monensin increased energic efficiency of volatile fatty acids, decreased adenosinetriphosphate (ATP) production, the amounts of fermented hexose, organic matter fermented and utilization of glucose (tab. III).(ABSTRACT TRUNCATED AT 250 WORDS) PMID:1641932

  19. Myths and errors in the x-ray practice in Bulgaria

    International Nuclear Information System (INIS)

    Full text: Insufficient awareness and knowledge on radiation risk and radiation protection of the medical specialists leads to serious errors. Some interesting facts, as well as widely spread myths and common mistakes in the radiology practice in Bulgaria shall be reviewed. Part of them is related to the insufficient knowledge of the characteristics and the resources of the X-ray equipment. Practice example is the usage of an improperly set automatic exposure control, without consideration of the exposure parameters it selected. The result is an exposure with too low tube current and long exposure time, which increases the dynamic unsharpness of the image. The lack of communication and feedback between the servicing companies and the medical staff after a technical support interacts with the diagnostic and the therapeutic processes. This could lead to poor image quality and wrong interpretation. A dangerous example is the statement from the service engineers that during emergency warm-up of the X-ray tube of a CT, the patient could be within the CT gantry. Their claim is that the warm-up is implemented with the collimator closed - a statement, rejected upon additional measurements and leading to unnecessary exposure of patient and/or the personnel, with a risk for appearance of a deterministic effect. It is important to have good communication and team work between each of the specialists, engaged into the application of the ionising radiation for diagnostic and therapeutic purposes - radiographers, technical support engineers, radiologists, interventional cardiologists, medical physicists etc. Insufficient awareness and knowledge of the used x-ray equipment and the principles of radiation protection, as well as the bad communication between the different specialists, could lead to serious incidents and accidents

  20. Closedown programme for the uranium ore and processing plant at Eleshnitsa, Bulgaria

    International Nuclear Information System (INIS)

    The tailings pond of the uranium ore and resin processing plant at Eleshnitsa, Bulgaria has been subject to a rehabilitation programme under a phare contract. The tailings cover 34 ha behind a 70 m high dam. The volume of waste is 12 million m3. Furhermore, there are considerable areas with contaminated soils within the industrial area. In order to be able to prepare detailed design and full tender documents for the actual contractual works a number of additional studies has been performed. The studies include geophysical, geodetical and geotechnical surveys, piezometer installations, a sub-regional sampling survey of surface and groundwater and a laboratory scale water treatment test. From these studies final design data and parameters have been obtained with respect to long term dam-stability, composition of cover and shape of contouring of the tailings pond area, structures for diversion of upstream surface waters and size and type of waste water treatment plant. Based on this information are contract Dossiers prepared The main part of this paper deals with the rehabilitation concept to be used for the contractual works. A description of present-day conditions, starting point for the rehabilitation concept, is also presented. Specific emphasis is put on the long-term stability of the dam and covering of the tailings by a soil membrane, on the design of the waste water treatment plant and on the monitoring programmes to be put into place. Besides above mentioned more technical and environmental aspects of the closedown programme a preliminary planning as well as cost-estimates for the different contractual works are presented.

    Full Text Available Land-use changes and afforestation activities are widely recognized as possible measures for mitigating climate change through carbon sequestration. The present study was conducted to evaluate the effect of afforestation on (i soil physical and chemical properties and soil carbon stocks in four mountain ecosystems and (ii whole ecosystem carbon storage. The four experimental sites, situated in the Western Rhodope Mountains (Bulgaria were characterized by typical forest-related land-use conversions. The four sites were a Douglas fir (Pseudotsuga menziesii [Mirb.] Franco plantation (Rd1 established on former cropland, a mixed black pine (Pinus nigra Arn. with Scots pine (Pinus sylvestris L. plantation (Rd2 established on former cropland, a cropland (RdA1 and an abandoned land with uncontrolled extensive grazing (RdA2 historically used as cropland. Soil parameters, i.e., sand content, pH, organic C and N contents, C/N ratio and soil organic carbon (SOC stocks, were significantly affected by land use and land-use history. Conversion from cropland into forestland significantly reduced soil bulk density and coarse fragments at 0-10 cm depth. Compared with adjacent cropland and abandoned land, soils in coniferous plantations were acidified in their upper layers. Sites Rd2 and RdA2 contained the least SOC owing to the previous long-term arable cultivation (>100 years. Analysis of the ecosystem C stock distribution revealed that most of C in forests was stored in the aboveground tree biomass. Our study confirmed that afforestation of cropland turned the soil into a C sink for the selected mountain region, but showed conflicting results when afforestation occurred on abandoned cropland.

    2007-01-01

    Full Text Available A new homogenous earthquake catalogue covering Bulgaria and the surrounding Balkan area has been created with intention of performing a consistent seismic hazard assessment across the region. In keeping with modern requirements of cataloguing seismicity, this catalogue has been made homogenous as far as possible with regards to magnitude, which has been provided on any of four different reported scales for each event; mb, Ms, Mw and ML. A key historical catalogue for the region has been used to represent the early instrumental period of earthquake recording (1900 to 1963, whilst data have been obtained from the International Seismological Centre (ISC, National Earthquake Information Center (NEIC and National Observatory of Athens (NOA to cover the instrumental period of earthquake recording (1964 to 2004. ISC data have also been used to develop a new mb→Ms magnitude conversion equation for the catalogued region. Application of this new magnitude conversion relation, in combination with other selected magnitude scale correlations, ensures reported magnitudes can be systematically rendered onto homogenized Ms and Mw scales for all earthquakes. This catalogue contains 3681 events with homogenized magnitudes ≥4.0 Mw, for the time interval 1900 to 2004 (inclusive, located in the region bounded by 39°–45° N, 19°–29° E, at focal depths of 0.0 km to 401.0 km and in a magnitude range 4.0≤Mw≤7.2. Selected large magnitude (M≥6.0 Ms earthquakes have had their reported magnitudes reassessed – and adjusted if necessary – in light of work by other authors. Applied statistical approaches aimed at determining the lower threshold to magnitude completeness suggest this catalogue is complete down to a homogenized surface-wave magnitude of 4.6 Ms.

    Full Text Available Introduction: There are five Bulgarian medical universities in the cities of Sofia, Plovdiv, Varna, Pleven and Stara Zagora. A major priority of medical universities is to encourage research activities mainly aimed at preparation and implementation of research projects. Projects are managed by the participating organizations called “beneficiaries”. Beneficiaries develop projects, apply for finances and if approved they implement those projects.Aim: The purpose of our study is to examine the organizational structure of research project activities on the macro level and on the micro level in Bulgarian medical universities.Material and methods: In order to define the separate elements of the organizational structure and to analyze the relations and interaction between them we have applied a documentary and sociological approach. Results: During the last six years there was a significant increase in the number and the overall annual financial value of the projects performed at medical universities in Bulgaria. The reasons for such increase are: managers realizing the advantages of and benefits from the implementation of research projects ensuring high quality modernization of research units’ equipment and facilities; access to innovative technologies; development of interdisciplinary relations, etc. Benefits arising from improved results motivate us to consider as appropriate some additional investments aimed at increasing the number of team members and further optimization of the currently existing structures (research centers in charge of research with the purpose of achieving even better results in this particular field. Conclusion: The role of research project activities in medical universities’ research field is of vital importance for the educational institutions’ success. Taking into consideration the changed conditions, European possibilities and the highly competitive environment, realizing this aspect will be essential for the

    Full Text Available The prevalence of craniomandibular disorders (CMD among the Bulgarian population as well as the risk factors for unlocking bruxism and bruxomania mechanisms pose a demand for education on these issues reflecting modern science. The authors' aim is to examine the subjective assessment of participants in “DAYS OF PROSTHETICS, Sofia, 15 -16 March 2014”, regarding: 1.Prevelance of CMD in the country; 2. Education and training of students and post-graduates in the issues related to diagnostics and treatment of craniomandibular disorders; 3. Theoretical background for successful treatment of patients with bruxism and bruxomania. Materials and methods: For the purpose of the present research 192 participants have been surveyed - among them 163 are dentists and 29 are students in the 4th and 5th year of study. The survey feedback has been obtained via an anonymous questionnaire consisting of 8 questions targeted at dentists' assessment of CMD prevalence and distribution, training in CMD issues in Bulgaria and the treatment of patients with bruxism and bruxomania. The results obtained indicate that 84.0% - 93.1% (95% CI of respondents, working as dentists in the country, expressed the view that students' curriculum lacks an overall concept for training them in the diagnostics and treatment of CMD. 79.6% - 90.2% (95% CI of participants, dentists in the country, define post-graduate training in CMD as insufficient or lacking. Conclusion: The development and promotion of a working platform for early screening, diagnostics and treatment of CMD for timely referral to a specialized treatment is necessary and expected by the professional community in our country.

    Full Text Available BACKGROUND The geographic proximity of parents and adult children is a key element of intergenerational solidarity. Many studies have identified geographical distance as an important determinant of intergenerational support: living nearby increases the amount of mutual support provided. It can, however, also be regarded as a dimension of intergenerational solidarity: the current degree of proximity is the result of past migration decisions made by both generations, in which present and future care demands potentially played a key role. OBJECTIVE We take this endogenous nature of geographical distance into account by examining theindirect effect of the determinants of the actual level of support through geographical distance. Both upward support (personal care provided to mother and downward support (help with childcare received from mother are considered. METHODS Path analyses are performed on data from the Generations and Gender Survey for France and Bulgaria using a general latent-variable modelling framework in multiple-group models. RESULTS In addition to strongly affecting the level of support provided and received, geographical distance itself is affected by several individual and family-related variables, which in turn have an indirect effect on the level of intergenerational support. The results suggest that proximity can be used as an adaptive strategy: e.g., working adult children in France receive more help with childcare because of their greater proximity to their mothers. Having a greater care need may have triggered this choice of residence. Similarly, single parents with no partner to rely on tend to live closer to their mothers, and therefore receive more help. CONCLUSIONS Geographic proximity can be considered a latent form of solidarity that functions as a mediator between background factors and manifest, functional solidarity.

    Full Text Available The paper analyzes the well-known historical works of George Akropolites and George Pachymeres from the viewpoint of their literary composition structure, lexica and narrative techniques used for describing events and personalities from Bulgaria and Serbia. An attempt is made to surpass the 'traditional' methodology and the usually applied standard approach that focuses almost exclusively to the search for the 'strong' historical facts in these literary works par excellence, in that way overlooking their strong literary character, careful expressions, sometimes evident and sometimes more subtle style differences whose purpose was to underline the focal points and the conclusions of the content of the stories - in short, the information and the stories about Bulgaria and Serbia by Akropolites and Pachymeres are analyzed in their entirety, viewed as the integral parts of the complex literary works, and not as isolated episodes, divided from the rest of the narrative. The ways in which George Akropolites depicted and described deaths of the Bulgarian rulers were studied as one of the best examples of his conscious endeavors to bring the literary style of his History in accord with his own judgments about the rulers of the neighboring country. Scenes of death, conspicuously frequent in Akropolites' relatively short historical work, play an important role in characterizing personalities, and the same principle which Akropolites uses for judging the Byzantines is applied to the Bulgarians as well: generally positive opinion about somebody's life and achievements is emphasized with a depiction of his death in a positive way (Ivan II Asen, and vice versa, Akropolites' 'villains' receive their horrible deaths as a deserved punishment for their bad deeds (Kalojan's death. On the other hand, Akropolites' scarce information about Serbs is supplemented with his depiction of the Serbian king Uroš (1243-1276, and his stance after the death of John Batatzes

    Full Text Available As a member of the European Union Bulgaria is subject to monitoring, including in the field of ecomomy. Our country complies with the rules and procedures imposed by the common European policy. Although recent analyses indicate a slight decline in corporate indebtedness, it also maintains the same high levels, thus it hides certain risks for businesses in all sectors of the economy. The delayed payment to a counterparty leads to an avalanche of delayed payments. The need for discipline, good faith and fair payments is tangible.

  15. A view to the intermediate-depth Vrancea earthquake of May 30, 1990: Case study in NE Bulgaria

    International Nuclear Information System (INIS)

    A deterministic analytical procedure for ground motion modelling, combining both modal summation and mode coupling techniques has been implemented to obtain synthetic seismic signals at Russe, NE Bulgaria, due to one of the strongest Vrancea intermediate-depth earthquakes, which occurred during the last century, May 30, 1990. The frequency content of the synthetic signals in different frequency ranges, up to 1 and 2Hz, has been studied separately. The results of this study, i.e. time histories and related ground motions parameters, can be used for different earthquake engineering analyses, e.g. structural performance assessments. (author)

    Full Text Available Abstract Background The Bulgarian and Greek Medical Care systems have been reformated the last fifteen years. The aim of this study was an examination and comparison of the Bulgarian and Greek Medical Care Systems. Methods This study was prepared by using all the published data related to both Bulgarian and Greek Medical Care systems. Besides, personal communications with related offices such as administration offices of hospitals and Ministries of Health were made. Results In both countries, besides the compulsory insurance there is also additional voluntary insurance which is provided by private companies. The most important difference is the family doctor (specialist in general medicine existing in Bulgaria. Every insured person needs a 'referral form' completed by the family doctor before visiting a hospital for medical attention (except emergencies. In contrast, in Greece an insured person can directly visit any hospital without needing any forms and independent of the severity of their health problem. An important disadvantage of the Greek health system is the low number of hospitals (139, in relation to population. In contrast, there are 211 hospitals in Bulgaria, although its population is lower than in Greece. Conclusion In both Greek and Bulgarian health systems changes must be done to solve the problems related to informal payments, limited financing, large debts, lack of appropriate investment policy, lack of an objective method for the costing of medical activities and inefficient management.

    Full Text Available The aim of this study was to validate Holland’s hexagonal and Tracey’s spherical model of vocational interests in young adults in Serbia and Bulgaria. To this end, 1250 participants, 560 from Serbia and 690 from Bulgaria, filled in Serbian and Bulgarian versions of the Personal Globe Inventory (PGI, Tracey, 2002. Hubert and Arabie’s randomization test of hypothetical orders, multidimensional scaling with fixed coordinates, Myors test and exploratory factor analysis were used. The results showed that the hexagonal and spherical models well explained the structure of vocational interests in both samples. The level of fit of the hexagonal model to the data obtained by using the PGI was generally higher than those established in the studies that used other Holland-based instruments. Furthermore, the levels of fit of both hexagonal and spherical model were in the same range like those obtained in previous studies in other countries. The results also pointed out a remarkable similarity in the structure of vocational interests in the Bulgarian and Serbian samples. [Projekat Ministarstva nauke Republike Srbije, br. 179002

    2005-03-01

    Soil samples from the vicinity of a non-ferrous metal smelter near Plovdiv, Bulgaria contained very high concentrations of cadmium, lead and zinc (up to 140, 4900 and 5900 mg kg{sup -1}, respectively). A roadside soil in a relatively uncontaminated area also contained high concentrations of the same metals (24, 1550 and 1870 mg kg{sup -1}, respectively) indicating that the transport of ores could be a source of contamination. Even though the lead isotope ratios in all the samples fell within a very narrow range (for example, 1.186-1.195 for {sup 206}Pb/{sup 207}Pb), the samples could be differentiated into three distinct groups: ores ({sup 206}Pb/{sup 207}Pb and {sup 208}Pb/{sup 207}Pb ratios of 1.1874-1.1884 and 2.4755-2.4807, respectively), current deposition (1.1864 and 2.4704-2.4711, respectively) and local background (1.1927-1.1951 and 2.4772-2.4809, respectively). Although most of the current deposition has its origin in the ores used at the smelter, up to 12% could be from other sources such as petrol lead. - Although soils in the vicinity of a non-ferrous metal smelter near Plovdiv, Bulgaria, have become highly contaminated with the ores used, lead isotope analysis has revealed that up to 12% of current deposition could be from other sources such as petrol lead.

  20. Application of the neo-deterministic seismic microzonation procedure in Bulgaria and validation of the seismic input against Eurocode 8

    International Nuclear Information System (INIS)

    The earthquake record and the Code for design and construction in seismic regions in Bulgaria have shown that the territory of the Republic of Bulgaria is exposed to a high seismic risk due to local shallow and regional strong intermediate-depth seismic sources. The available strong motion database is quite limited, and therefore not representative at all of the real hazard. The application of the neo-deterministic seismic hazard assessment procedure for two main Bulgarian cities has been capable to supply a significant database of synthetic strong motions for the target sites, applicable for earthquake engineering purposes. The main advantage of the applied deterministic procedure is the possibility to take simultaneously and correctly into consideration the contribution to the earthquake ground motion at the target sites of the seismic source and of the seismic wave propagation in the crossed media. We discuss in this study the result of some recent applications of the neo-deterministic seismic microzonation procedure to the cities of Sofia and Russe. The validation of the theoretically modeled seismic input against Eurocode 8 and the few available records at these sites is discussed. (author)

  1. The Byzantine Church of '40 Holy Martyrs' in Veliko Turnovo, Bulgaria: Pigments and Technique

    International Nuclear Information System (INIS)

    The 'St. 40 Martyrs' church is the most famous medieval building in Veliko Turnovo, Bulgaria. It is located in Assenova mahala, just next to Tsarevets. It was built and its walls were painted during the reign of Bulgarian king Ivan Assen II after the victory against Epyrus despot Theodoros Comninos (1230 AD). It consists of two buildings - a six-column basilica and another, smaller building on its western wall, which was built later. During the presence of the Ottoman Turks, maybe until the first half of the 18th century, the church remained christian. When it was converted to a mosque, all the christian symbols in it were destroyed. The archeological researches on site were initiated in 1969. As it is clear, the 40 Martyrs church is a historical monument of culture with great significance. The church had murals, from the earlier period, but in the following years and especially during the Ottoman period, the church has suffered many and different destructions. Nevertheless, the very few pieces of murals that are rescued till nowadays provide important information for the technique and the pigments that were used on its wall paintings. In the present work, twelve series of samples from the wall paintings were studied in order to characterize the materials and the technique used for church iconography. The study was based on the micro-analytical techniques of the Fourier Transform Infrared micro-spectroscopy (μs-FTIR), the Optical Microscopy and the Scanning Electron Microscopy (SEM) coupled to an Energy Dispersive X-ray Spectrometer (EDS). In the FTIR spectra of all pigments the characteristic peaks of calcite were detected, confirming the use of fresco technique for the creation of murals. The combination of FTIR spectroscopy and SEM-EDS analysis, reveal the existence of lapis-lazuli for the blue color, green earth for the green color, cinnabar for the red color, calcite for the white color and carbon black for the black color. Moreover, in other chromatic layers

  2. Development of the radioactive waste management infrastructure in Bulgaria - preconditions and challenges

    International Nuclear Information System (INIS)

    In Bulgaria there are preconditions for development of an effective system, considering the interdependence between all stages of radioactive waste /RAW/ generation and management. The national infrastructure of RAW management is built up in accordance of the classical triangle principle, i.e. the main responsibilities are of the Regulatory body, waste producers and newly created State Enterprise RAW. The organization of the infrastructure is legislatively established and aims at application of the basic internationally adopted principles of radioactive waste management. The national policy is directed towards spent fuel and radioactive waste management in a safe, economic, comprehensive and integrated approach, where the historical aspect and contemporary trends, the country's scientific, technical and financial resources are considered, and the responsibilities of the state and of the nuclear facilities operators are clearly defined. The strategic purposes of the policy and the measures for their achievement are formulated in the National Strategy on Safe Management of Spent Fuel and Radioactive Waste. The tendency is a joint national system for management of spent fuel and radioactive waste from nuclear power production and nuclear applications to be established. Decisions for storage of high level waste from spent fuel reprocessing, as well as of spent fuel, are considered in long-term perspective and possibilities at regional level are analyzed as well. The safe and effective RAW management is a precondition for the sustainable development of the Bulgarian nuclear program, including decommissioning of units 1 and 2 of Kozloduy NPP, completion of the Belene NPP construction, and use of the benefits offered by the radiation technologies. The main challenges are connected with: Establishment of a new RAW classification and of clearance levels; Encouraging the re-use and/or recycling of radioactive materials, equipment and buildings, within the framework of the

    This study examines neonatal group B streptococcal (GBS) colonization and its relation to early-onset GBS disease (EOGBSD), based upon the experience of leading obstetrics and gynecology centers in Bulgaria. The objectives of the study were to update neonatal colonization rates and to assess relationships between clinically differentiated cases (culture-proven GBS newborns) and risk factors inherent to the infant and mother, using a computerized file. The neonatal GBS colonization rate ranged from 5.48 to 12.19 per 1000 live births. Maternal-fetal infection (MFI, a provisional clinical diagnosis in culture-proven colonized infants with initial signs of infection that is usually overcome with antibiotic treatment) and/or intrapartum asphyxia (IA) have been demonstrated as the most frequent clinical manifestations, with significant correlations for the primary diagnosis, but not affirmative for the final diagnosis at discharge, resulting from adequate treatment of neonates. MFI and IA were significantly related to prematurity, and reciprocally, prematurity was associated with the risk of MFI, indirectly suggesting that preterm birth or PPROM (preterm premature rupture of membranes, an obstetric indication associated with early labor and delivery, one of the major causes of preterm birth) is a substantial risk factor for EOGBSD. The regression analysis indicated that in the case of a newborn with MFI, a birth weight 593.58 g lower than the birth weight of an infant without this diagnosis might be expected. Testing the inverse relationship, i.e., the way birth weight influences a certain diagnosis (logistic regression) established the presence of a relationship between birth weight categories (degree of prematurity) and the diagnosis of MFI. The proportions and odds ratios, converted into probabilities that a baby would develop MFI, indicate the particularly high risk for newborns with extremely low and very low birth weight: extremely low birth weight (≤1000 g), the

    International Nuclear Information System (INIS)

    The Belene site on the Danube River was approved by the Bulgarian Government in 1981 for the construction of a second nuclear power plant in Bulgaria. The same year, preparation of the site preparation commenced with: -Construction of anti-filtration walls; -Erection of external communications, civil and installation facilities. To avoid the risk of site flooding, the terrain was built up by eight meters and levelled at the same time. By 1989 the following erection works were completed: -Circulation pipelines; -Units 1 and 2 ballast mats; -Unit 1 reactor building up to elevation 13.20 m, and the foundation and support structure of the turbine hall; -Diesel generators cubicles. In 1990, the Bulgarian Government decided to suspend project execution due to financial difficulties. Since then, multiple measures have been undertaken to preserve the equipment supplied, the construction site itself and the buildings. Various investigations and assessments have been carried out with respect to the site suitability and the equipment status, all of which yielded positive conclusions. New investigations were conducted in relation to site safety and its compliance with international safety requirements. An extensive research on the seismic safety of the Belene site was carried out. A number of missions were dispatched by the IAEA and other authorities. All these came up with positive conclusions and confirmed that the Belene site was suitable for the construction of a new nuclear power plant. At the end of 2002, the Bulgarian Government took a decision in principle to re-start construction at the Belene site. An Environmental Impact Assessment was carried out in the period from October 2003 to November 2004, and the final report was submitted for public discussions in both Bulgaria and Romania. The procedure ended up successfully, resulting in Decision No.18-8 from the Ministry of Environment and Waters, dated November 22, 2004, to approve the investment proposal for the

    International Nuclear Information System (INIS)

    The Bulgarian Nuclear Society (BgNS) was founded in 1991. The priorities of the BgNS activities were clearly outlined during its more than ten years of experience. Organizing conferences, seminars, scientific sessions where discussions are freely deployed the BgNS assists the professionals and lays out its stand on particular matters, related to the nuclear energy development, radiobiology and radiation protection. The BgNS events are always open to the public. Journalists and representatives of governmental and non-governmental organizations are involved. The information policy of the society is focused on extending the knowledge and culture of the population about nuclear power and radiology issues. A wide range of communication approaches is used, such as publications, meetings, discussions, exhibitions, media events and Internet. The BgNS experts provide competent assistance to the state authorities and non-governmental organizations for finding optimal solutions in nuclear technologies and atomic energy. The 'BgNS Transactions' has an authority among the specialists connected with that sector of industry. The BgNS carries out constructive co-operation with national nuclear societies in Romania, Ukraine, the Czech Republic and Russia. Since its foundation the BgNS is a regular member to the European Nuclear Society. Contributing to the development of nuclear science and nuclear energy in Bulgaria, the BgNS keeps its priorities for extending the information exchange between professionals on national and international level and for providing the Bulgarian population with information about the up-to-date nuclear technologies in the variety of their aspects. The BgNS is a non-governmental organization aimed at multilateral development of science, technology and practice for safe use of atomic energy for peaceful purposes. It contributes for creating of attitudes and right climate of opinion about nuclear power matters. BgNS incorporates prominent scientists

  9. Quality control in diagnostic radiology in Bulgaria - Regulation, implementation, procedures, first results

    International Nuclear Information System (INIS)

    Full text: X ray equipment in Bulgaria comprises about 1200 conventional radiography units, 650 image intensifier based fluoroscopy systems, 15 modern angiography systems, 110 computed tomography (CT) scanners, 140 dedicated mammography units, 610 dental units and 9 DEXA systems. Quality assurance (QA), as a means for optimization of patient radiation protection was legally introduced in the country in October 2005 with a new Ordinance of the Ministry of Health for Protection of Individuals at Medical Exposure. It requires Quality control (QC) of imaging equipment and patient dose measurements to be implemented as an important physical and technical aspect of QA. QC programmes were elaborated and are presented here for each type of X ray diagnostic equipment - for conventional radiography, fluoroscopy, mammography, CT and dental radiology. They include a list of parameters to be tested, level of expertise needed, as well as two action levels: remedial and suspension. On the basis of the international experience, measurement protocols were developed for all parameters tested. This work presents the first results of implementation of the QC programme for a number of X ray units of different types. The local protocols of three groups working independently were collected and this database was used to analyse the results by specially designed software. The survey comprises commissioning tests of 40 conventional radiography, 15 fluoroscopy and 10 mammography units of different ages and gives fist overview on the status of the X ray equipment in the country. The important parameters having suspension levels were analysed - tube potential accuracy and reproducibility, half value layer and corresponding tube total filtration, timer accuracy, absolute value and reproducibility of the tube output. Additionally for radiography equipment were tested the light and X ray field alignment, film processor performance and dark room conditions. For fluoroscopy were included also tests

  10. Yield of PV-generated energy by small scale PV system at a site of Sofia, Bulgaria

    International Nuclear Information System (INIS)

    A 36W PV module has been installed on the building of Solar Energy Lab in Sofia. The purpose of this demonstration is to determine practically the amount of energy can be produced for a fixed period of time and to assess the opportunity for solar power application in small utility systems in Bulgaria. This paper reports the results of testing a module over spring and summer time when solar insolation reaches its maximum. The data measured include operation weather variables, DC and thermal performance of a module. These data were analyzed to calculate average PV-generated energy for a sunny day and for a whole month (April 1995). Empirical thermal dissipation coefficient for the developed module assembly is also extracted from the data. (author). 1 ref., 4 figs

    For the first time in Bulgaria, a deletion/duplication screening was performed on a group of 84 unrelated Duchenne/Becker muscular dystrophy patients, and the breakpoint distribution in the dystrophin gene was analyzed. Intragenic deletions were detected in 67.8% of patients, and intragenic duplications in 2.4%. A peculiar distribution of deletion breakpoints was found. Only 13.2% of the deletion breakpoints fell in the {open_quotes}classical{close_quotes} hot spot in intron 44, whereas the majority (> 54%) were located within the segment encompassing introns 45-51, which includes intron 50, the richest in breakpoints (16%) in the Bulgarian sample. Comparison with data from Greece and Turkey points at the probable existence of a deletion hot spot within intron 50, which might be a characteristic of populations of the Balkan region. 17 refs., 2 figs.

  13. Application of mineral fertilizers in Bulgaria and their efficiency on the slightly leached chernozems of the Dobroudja region

    International Nuclear Information System (INIS)

    Over the past years the agriculture in Bulgaria is undergoing a process of reconstruction and structural changes. The utilization of mineral fertilizers has gradually increased since 1948 and reached its summit in 1981 when about 227 kg/ha NPK have been used. Nowadays these norms have been were and in 1996 they were only 35 kg/ha at the expense of applying N-fertilizers mainly in wheat. The efficiency of the applied nutrients was estimated on slightly leached chernozem in the period 1967-1997. The regular long term fertilization of N120P60K0 had a favorable effect on grain yield in an agronomical and economic aspect (5070 kg/ha). The highest grain yield was received at fertilization with N120P120K120 (5230 kg/ha). Refs. 4 (author)

  15. The trends in the social opinion for the nuclear energy development in Bulgaria during the last five years

    International Nuclear Information System (INIS)

    The sociological investigations in Bulgaria about the development of nuclear energy show that generally most of the people understand the importance of the nuclear power production in the country and are inclined to support it if the necessary safety level is guaranteed. 53.2% are against the early shutdown of the Kozloduy NPP units 1-4. Only 9.6% think that the authorities give adequate information about the atomic energy production. 34.6% are of the opinion that the actions of the authorities are unclear and that the population is not informed enough about them. A common opinion is that the public relations should be extended and the people need more information in the field of nuclear energy

    A severe radiation accident occurred on 14 June 2011 in an industrial irradiation facility for medical equipment sterilization in Bulgaria. Five people were exposed for 5-10 min to a 60Co source containing 137 TBq. The Emergency Department of the National Centre of Radiobiology and Radiation Protection (NCRRP), Bulgaria, put into practice the plans for providing medical care in radiation accidents and the procedures developed for assessment of injury severity, the decision-making algorithm regarding subsequent treatment, and the therapy for persons affected. The activities performed for initial assessment of the severity of injury of irradiated patients were published in 2012. Based on predictive assessments of the severity of radiation damage, it was decided that the victims required hospitalization at a specialized hematology clinic. Percy Hospital in Paris was chosen for this purpose. The aim of this report is to present the results of 1-y follow-up for three of the victims. Sadly, 1 mo after the accident, Patient 4 died from a heart attack. The medical opinion was that this was not a direct outcome of the irradiation. Patient 5 was only followed up for 4 mo (118 d) because medical follow-up is voluntary, and despite repeated calls, the patient did not respond. Medical examinations by a physician as well as hematology and biochemical tests were performed using standard laboratory methods. The obtained results were compared to the victims' personal reference limits obtained from annual health monitoring. After the accident, the recovery to normal content of peripheral blood cells was observed in all victims. Nevertheless, there were observed cases of thrombocytopenia, granulocytopenia, and leucocytopenia at various times after exposure. During the period of observation, morphological changes in red blood cells such as anisomicrocitosis, macrocytes, megalocytes, and polychromatic erythrocytes were demonstrated. During the 1-y observation period, all victims showed

    Full Text Available The genetic polymorphism in selectively reared in Bulgaria, local honey bee populations of Apis mellifera macedonica subspecies (type rodopica, has been studied, using analysis of six enzyme systems (MDH-1, ME, EST-3, ALP, PGM and HK corresponding to 6 loci. Totally 458 worker bees from 12 bee breeding bases for artificially inseminated queens were used for this study. All these stations are part of the National Bee Breeding Association which officially implements a National Program for sustainable beekeeping in Bulgaria. All of the six loci were found to be polymorphic. Only EST-3 locus was established as fixed in one of the investigated populations. Polymorphism with three alleles was ascertained for MDH, ME, ALP, PGM and HK loci and with five alleles for EST-3 locus. The most common alleles in almost all of the populations were MDH-1 100, ME 100, EST-3 100, PGM 100 and HK 100. Two private alleles (frequency < 0.05 were found for two of the populations. The calculated level of polymorphism was 88.33% in only one of the populations and 100% - in all others. The observed and expected heterozygosities (Ho and He ranged from 0.157 to 0.250 and from 0.206 to 0.272, respectively. The estimated mean FST value from allozyme data was 0.035. On the bases of the allele frequencies of the studied allozyme loci the Nei's (1972 genetic distance was estimated. It ranged between 0.002 and 0.060 among the populations studied.

    2008-11-01

    We explore trends in first-union formation in Bulgaria from 1960, using data from the national Gender and Generations Survey of 2004. We analyse jointly the transition into cohabitation and directly into marriage. The standardized marriage rate falls dramatically from the early 1980s; the corresponding rate of entry into cohabitation has already increased from the early 1960s but (surprisingly) falls moderately toward the end of our period. Cohabitation also tends to last progressively longer in more recent periods. The analysis shows that a pregnancy leads to a dramatic increase in the rate of both kinds of union formation: the increase is by a factor of almost 20 for marriage formation and about 10 for entry into cohabitation, ceteris paribus. Our findings suggest that, in Bulgaria at least, some manifestations of the Second Demographic Transition can be detected as early as the 1980s. PMID:18937141

    Full Text Available The study presents archaeobotanical analyses of four Early Neolithic sites (Koprivets, Orlovets, Dzhulyunitsa, Samovodene from Northeast Bulgaria. Those archaeobotanical data are linked to comprehensive series of 14C dates for the early Neolithic in northeastern Bulgaria allowing their attribution to high resolution radiocarbon chronology. In the considered sites the dominating cereal crop during the Early Neolithic is hulled barley (Hordeum vulgare var. vulgare, followed by einkorn (Triticum monococcum and few emmer (Triticum dicoccum what is a clear difference from the southern parts of Bulgaria where during the early Neolithic the dominating cereal crops are einkorn and emmer. Further principal crops, present from the earliest phases of the Neolithic in the region are lentil - Lens culinaris, pea – Pisum sativum, grass pea – Lathyrus sativus/cicera and flax – Linum usitatissimum. Wide spectrum of finds of gathered plants (at least 11 taxa reflects the use of the natural vegetation resources. Useful for reconstructing the vegetation and land use in the Neolithic are also wood charcoal identifications, indicating apart of oak forests also presence of open vegetation, riparian forests and wetlands. The relatively open vegetation in the surrounding of the early Neolithic settlements could be one of the reasons why the corresponding locations were chosen by the Neolithic people to settle there. On the other hand this open vegetation could be caused by the Neolithic land use and animal husbandry, which have also led to certain reduction of the forests in the immediate surroundings of the settlements.

    Full Text Available Agriculture/horticulture has traditionally been an important sector in the economy of Bulgaria. The paper outlines the structural changes in Bulgarian agriculture since 1989 and discusses the product and market orientation of the horticultural farms in the Plovdiv region of Bulgaria. This paper analyses how farm owners / managers with different sized farms evaluated 5 product/market strategic options: ‘doing what you currently do but better’, ‘developing new horticultural products’, ‘developing new markets’, ‘developing new agricultural activities’ and ‘developing new nonagricultural activities’. The owners / managers identifi ed; whether they perceived these options as feasible for their future development, the encouraging/discouraging factors and the outcomes they expected from their implementation. The small-scale farms (less than 2 ha were mainly subsistence farms that were relying upon the farmer’s experience to survive during the transition period. The second type of farm (2-10 ha was ‘transitional’ farms and were working under pressure either for survival or expansion under the new EU related conditions. The third type of farm (over 10 ha was more business orientated, aiming at business viability and trying to respond to the rapidly changing business environment in Bulgaria as they recognised that the EU accession would present new challenges and opportunities for the successful future development of their farm businesses.

  10. Adapting to Sea Level Rise and Storms: Missed Opportunities and Continuing Development (case studies from USA and Bulgaria)

    Over the last several years, there have been significant discussions within the global scientific and coastal zone management communities about the need to adapt to the realities of long-term sea level rise and to make coastal development more "resilient" to hazards and climate change. With all of the talk, publications, and recognition of the problem, you would think that we had made significant progress, but this is not the case. Once again, the USA has experienced the impact of a significant coastal storm, Hurricane Sandy. There were initially some serious post-Sandy discussions regarding the need to ensure that we simply don't "just put everything back were it was." Almost a year later, there have been few substantive moves to relocate property away from coastal hazards or to change the footprint of vulnerable coastal communities. This is particularly true of coastal resort communities in New York and New Jersey. Some communities have initiated large-scale efforts to elevate (in situ) infrastructure and private property. Raising buildings is only a workable solution if you also commit to holding all the beaches in place . . . forever. This is what the federal government has done for New Jersey and New York. The U. S. Army Corps of Engineers will be spending upward of US5 billion on shore protection projects following Hurricane Sandy. The vast majority of these funds will be spent pumping sand onto beaches from Delaware to Connecticut. The amount of sand they will move is staggering, approaching 25 to 35 million cubic meters. This is an adaptation model that cannot be exported to the rest of the USA. Nor can it be maintained for an extended period of time. Along the Black Sea Coast of Bulgaria the risk of storms is not as great as that of the US East Coast, but long-term sea level rise is still a threat. In Bulgaria, most coastal development problems occur simply because people continue to build in areas that are too close to the coast or in very high hazard

    Full Text Available The process of recreating of the basic herds of the farm animals and the improvement of their breedconstitution, which has already begun in Bulgaria, is a prerequisite for the providing of more, and of betterquality, meat and milk for the needs of the domestic market, as well as for making the sector morecompetitive on the international markets. The purpose of the research concerned comparative analysis andtendencies in the development of the cattle market in the conditions of the quota system in the EU countriesand Bulgaria.One of the reasons for the decrease of the quantity of exported cattle and veal meat is that there isshortage of resources in the manufacturing industry, which to a great extent limits the export with thepurpose of satisfying the needs of the inner market.This quota will give Bulgaria the chance to export for the EU 2000 t. with zero customs tax.Although Bulgaria cannot make use of this opportunity for the moment, as there is not approved factory forproduction of meat to be exported to EU, we think that it as a good opportunity. It could be stimulating or thecompanies to take a step in this direction.The calculations show that after the countries of Central and Eastern Europe join the EU, theproduction of meat in the EU will increase by 20%. This however, will not lead to flooding of the marketbecause an increase of the income of the joining countries is expected, with a resulting increase ofconsumption. On the other hand, an increase of the export of meat and meat products is expected for thetraditional markets in Russia.The advantages of the quota system which is being introduced in Bulgaria, as part of the agrarianpolicy of the EU, directed at preventing of overproduction at the market, can be structured as follows:Providing guaranteed prices for the cattle products; Imposing financial sanctioned at exceeding theproduction quota; Opportunity for introducing two-stage quotas – a high price for the production for the

    Full Text Available Nowadays, public employment services face a number of urgent tasks as raising the employment rate and reducing the number of vacant jobs for which is difficult to find enough qualified workers. New realities on labour market and dynamic environment require adequate actions, rational and timely decision making and optimization of work. Dynamic changes in social environment impacting labour markets and activities of public employment services impose various tasks which implementation should be carefully planned, organized and controlled. To achieve that public employment services should take a more comprehensive look at the demand and supply of labour, considering the numerous transitions taking place constantly on the labour market and people's personal development. Improving processes and the quality of the administrative services in the Bulgarian employment agency is seen as a prerequisite for effective implementation of employment policies. The study presents opportunities for improving the quality of services offered in the Directorates "Labour Office" in the Republic of Bulgaria by introducing a process model and improvements in the capacity and efficiency of work in the field of labour mediation.

    The present study aimed to determine the role of human parvovirus В19 (B19V) as an aetiological agent in measles and rubella negative fever/rash patients from Bulgaria between 2004 and 2013. A total of 1,266 sera from all over the country were tested for B19V IgM antibodies and all positives were further investigated by polymerase chain reaction (PCR). Overall, 280 sera (22%) were B19V IgM positive and 227 of these (81%) were also PCR positive. The highest number of IgM positives was found among five to nine year-old children (27%). Eight infected women gave birth to healthy children; one fetus was aborted with hydrops fetalis. Of the 55 genetic sequences obtained, 54 belonged to genotype 1a and one grouped as a genotype 2 outlier. Phylogenetic analysis of all available genotype 2 sequences covering the 994 nucleotide non-structural protein 1(NS1)/capsid viral protein 1 (VP1) unique region junction, showed that only one other sequence grouped with the outlier strain, forming a clearly distinct and well-supported cluster of genotype 2 (between-group genetic distance: 3.32%). In accordance with B19V nomenclature, this cluster may represent a new subgenotype 2b. The study showed that B19V infections may be falsely identified as rubella or measles in ca 22% of cases, emphasising the need for laboratory confirmation. PMID:26847955

    Full Text Available The EU-TecNet monitoring network uses customized three-dimensional extensometers to record transient deformations across individual faults. This paper presents the first results from two newly established monitoring points in the Balkan Mountains in Bulgaria. The data from Saeva Dupka, recorded across an EEN-WWS striking fault, show sinistral strike-slip along the fault and subsidence of the southern block. Much of the subsidence occurred around the time of the distal MW = 5.6 Pernik Earthquake. An important transient deformation event, which began in autumn 2012, was reflected by significant compression and following extension, across the monitored fault. The data from Bacho Kiro, recorded across a NE–SW striking fault, show sinistral strike-slip along the fault and subsidence of the north-western block. The same important deformation event was reflected by changes in the strike-slip, dip-slip, and horizontal opening/closing trends. These results have been compared to data from other monitoring points in the Western Carpathians, External Dinarides, and Tian Shan. Many of the sites show evidence of simultaneous displacement anomalies and this observation is interpreted as a reflection of the plate-wide propagation of a tectonic pressure pulse towards the end of 2012.

    Full Text Available Abstract Background Despite the attention the situation of the Roma in Central and Eastern Europe has received in the context of European Union enlargement, research on their access to health services is very limited, in particular with regard to child health services. Methods 50 qualitative in-depth interviews with users, providers and policy-makers concerned with child health services in Bulgaria, conducted in two villages, one town of 70,000 inhabitants, and the capital Sofia. Results Our findings provide important empirical evidence on the range of barriers Roma children face when accessing health services. Among the most important barriers are poverty, administrative and geographical obstacles, low levels of parental education, and lack of ways to accommodate the cultural, linguistic and religious specifics of this population group. Conclusion Our research illustrates the complexity of the problems the Roma face. Access to health care cannot be discussed in isolation from other problems this population group experiences, such as poverty, restricted access to education, and social exclusion.

    Full Text Available The high mountain lakes in the Rila Mountains (Bulgaria were studied in the years 2000 and 2001 considering the following groups of variables: geography, geology, morphology, hydrology, water chemistry of the pelagial, biomass and size structure of bacterio- phyto- and zooplankton, and occurrence of three fish species. Multivariate analysis (RDA revealed that the nutrient concentrations in the lakes were significantly influenced by the soil percentage coverage of the catchment area. The explained variation in plankton components (bacterio-, phyto- and zooplankton and plankton size structure was determined by biological as well as morphometrical and geographical variables. Changes in the Mg2+ and NO3-N concentrations were traced over the period 1993- 2001; the Ca2+ concentration, pH, nutrients, bacterio-, phyto- and zooplankton were monitored in the period 1995-2001. A nutrient decrease accompanied by an increase in size of zooplankton organisms in the period 1995-2001 led to a considerable increase of water transparency in the lakes.

    Full Text Available Orobanche cumana is a holoparasitic plant naturally distributed from central Asia to south-eastern Europe, where it parasitizes wild Asteraceae species. It is also an important parasitic weed of sunflower crops. The objective of this research was to investigate genetic diversity, population structure, and virulence on sunflower of O. cumana populations parasitizing wild plants in eastern Bulgaria. Fresh tissue of eight O. cumana populations and mature seeds of four of them were collected in situ on wild hosts. Genetic diversity and population structure were studied with SSR markers and compared to weedy populations. Two main gene pools were identified in Bulgarian populations, with most of the populations having intermediate characteristics. Cross-inoculation experiments revealed that O. cumana populations collected on wild species possessed similar ability to parasitize sunflower to those collected on sunflower. The results were explained on the basis of an effective genetic exchange between populations parasitizing sunflower crops and those parasitizing wild species. The occurrence of bidirectional gene flow may have an impact on wild populations, as new physiological races continuously emerge in weedy populations. Also, genetic variability of wild populations may favour the ability of weedy populations to overcome sunflower resistance mechanisms.

  18. Rational control of technical and economic characteristics in TPP burning lignites ('Maritsa East 2' TPP's experience - Bulgaria)

    International Nuclear Information System (INIS)

    'Maritsa East 2' TPP is one of the three power plants, situated in the area of the biggest coal field in Bulgaria. In the beginning of 1996 the thermal power plant had installed capacity 1450 MW. The effective and rational control of the production process is predetermined to a considerable extent by the level of the introduced automation. That is why since the end of 1989 an information and control microprocessor system MIK-2000 has been developed and next MIK-4000. The installed microprocessor systems have functional structure comprising the technological processes of the units and the whole plant. They include the operation stations of the units and the working places of the plant management, the production and technology department, the dispatch information unit and the main departments. The information and control microprocessor system (ICMS) performs operating, information and computing purposes. Use of automated systems by the plant personnel for information and control of technological, technical and economic parameters helps better operation control and enables formation of proper corrections in equipment operation mode

  19. Implementation of the European protocol for quality control of the technical aspects of mammography screening in Bulgaria

    International Nuclear Information System (INIS)

    The results from the national pilot project on implementation of the European protocol for the quality control (QC) of the technical aspects of mammography screening as well as the European protocol for dosimetry in mammography in Bulgaria are presented. A QC programme for mammography equipment and a standardised measurement protocol were created. The full QC programme was tested on four mammography units of different types and ages. A national survey was performed for entrance surface air kerma (ESAK) on 20 units using a 45 mm PMMA standard phantom. Average glandular dose (AGD) was calculated using the conversion coefficients from the European dosimetry protocol. The survey demonstrated considerable differences in the technical condition of the mammography units that resulted in varying image quality. The measured values of ESAK showed significant variations. Doses for ∼45% of the units were found to be below the European reference level. The values for AGD ranged from 0.35 to 3.47 mGy. The main problems found were film processing, optical density (OD) control settings and AEC adjustment. The results showed the importance of film OD measurements parallel to dose measurements. The X-ray mammography in the country needs optimisation. Comprehensive quality assurance programme should be adopted in all departments covering permanent QC of the equipment, image quality and breast dose. (authors)

    Full Text Available Gneisses from the deep structural levels of the European Variscan Belt are well exposed in the Central Sredna Gora in Bulgaria. In general, migmatites predominate, but unmigmatized domains (or domains with incipient migmatization are also documented in this area. This paper presents new structural, petrographic and U-Pb isotope geochronological data from such an unmigmatized part of the Variscan high-grade metamorphic basement (the Koprivshtitsa Unit. A predominant part of this unit represents an alternation of metagranitoids and metabasites. The protolith crystallization age of the metagranitoids is constrained at 491.5 ± 7.6 Ma by U-Pb laser ablation method on zircons. This age coincides with the previously available Late Cambrian protolith ages of metabasic rocks that crop out within the adjacent migmatitic unit. The Korpivshtitsa Unit comprises also lesser orthogneisses with Late Neoproterozoic protoliths. Based on the available local and regional paleogeographic reconstruction schemes, we suggest that the Upper Cambrian magmatic rocks intruded Upper Neoproterozoic crust during the initial opening stages of the Rheic Ocean or a related basin. Subsequently, both were involved in the Variscan high-grade deformation. The contact of the Koprivshitsa Unit with the migmatitic part of the metamorphic complex coincides with a north-vergent greenschist facies thrust zone – the Chuminska Shear Zone. The exact time of the shearing is still not well constrained but it clearly postdates the Variscan high-temperature metamorphism of the gneisses.

    Full Text Available The paper approaches territorial cohesion in SEE from the perspective of social equity with regard to the opportunity to choose to live in one’s native place without compromising the quality of life. It is interested in border areas - both physical and virtual; in real life situations as meeting points of theories and policies influencing human lives; and in the emerging challenges there that often make us question once and again our concepts and actions as experts. Based on the Bulgarian case-study analysis, the authors discuss the effectiveness and current challenges of real-life implementation of EU and national policies aimed at sustainable development of peripheral regions. The rural peripheral municipality of Ivaylovgrad is an indicative case study for the ongoing processes in the peripheral regions of Bulgaria and the efforts to overcome a continuing loss of working places, services, markets and further isolation from the rest of the country since the early 1990s. The paper presents a critical view of initiatives and projects undertaken by interest and local groups in the period 2006-2010. Possible innovative approaches for regional revival are considered and conclusions are drawn about the importance of creating development strategies sensitive to the existing and emerging socio-cultural patterns.

    2007-01-01

    The Mesta-Nestos river basin in Bulgaria and Greece is a case study for transboundary decision-making support in south-eastern Europe and a show-case for the development of methodologies and information-gathering for the integrated regional planning of water resources. Land-use conflicts in this water-scarce region cover a wide spectrum of activities like agricultural irrigation, drinking water production, diversions for industrial water, and risk of pollution from mining, to name a few examples.Measurements of the water quality were carried out in the upper basin. Results will be illustrated by the example of the environmental situation in the alpine region of the Pirin National Park as well as in the Razlog Basin with a stronger anthropogenic impact and pollution around a former uranium mine near the village of Ele(s)nica. The social and economic development of this transboundary region is a recently established priority for the future. It will mean an increase in water usage and more stress for the water resources if regional impacts of global climate change are verified. Problem-focused management of the catchment area as a whole on the basis of proved geo-data sets is needed for the future.

  4. Dependence of biologically active UV radiation on the atmospheric ozone in 2000 - 2001 over Stara Zagora, Bulgaria

    International Nuclear Information System (INIS)

    This study investigates how the changes in simultaneously measured ozone columns influence the biologically active UV irradiance. Spectral ground-based measurements of direct solar ultraviolet radiation performed at Stara Zagora (42oN, 25oE), Bulgaria in 2000 - 2001 are used in conjunction with the total ozone content to investigate the relation to the biologically active UV radiation, depending on the solar zenith angle (SZA) and the ozone. The device measures the direct solar radiation in the range 290 - 360 nm at 1 nm resolution. The direct sun UV doses for some specific biological effects (erythema and eyes) are obtained as the integral in the wavelength interval between 290 and 330 nm of the UV solar spectrum weighted with an action spectrum, typical of each effect. For estimation of the sensitivity of biological doses to the atmospheric ozone we calculate the radiation amplification factor (RAF) defined as the percentage increase in the column amount of the atmospheric ozone. The biological doses increase significantly with the decrease of the SZA. The doses of SZA=20o are about three times larger than doses at SZA=50o. The RAF derived from our spectral measurements shows an increase of RAF along with the decreasing ozone. For example, the ozone reduction by 1% increases the erythemal dose by about 2%. (authors)

  5. An innovative assessment of the seismic hazard from Vrancea intermediate-depth earthquakes. Case studies in Romania and Bulgaria

    International Nuclear Information System (INIS)

    An advanced procedure for ground motion modelling, capable of synthesizing the seismic ground motion from basic understanding of fault mechanism and seismic wave propagation, is applied to the case studies of Bucharest (Romania) and Russe, NE Bulgaria, exposed to the seismic hazard from Vrancea events. Synthetic seismic signals along representative geological cross sections in Bucharest and Russe have been computed and the energetic input spectra have been derived both from the synthetic signals and the few existing records. The theoretical signals are successfully compared with the available observations. The site response has been calculated for three recent, strong and intermediate-depth, Vrancea earthquakes: August 30, 1986 and May 30 and 31, 1990. The used approach differs significantly from the today's engineering design practice that relays upon rock-site hazard maps and applies the site correction at a later stage. The obtained results show that it is very useful to estimate the site effect via waveform modelling, considering simultaneously the geotechnical properties of the site, the position and geometry of the seismic source and the mechanical properties of the propagation medium.

  6. Zeolite rocks from the paleogene lacustrine volcano-sedimentary deposits in Gorna Glogovitsa Graben (Kraishte region, Western Bulgaria)

    International Nuclear Information System (INIS)

    Analcime-clinoptilolite and clinoptilolite-analcime zeolite rocks established in the Paleogene deposits of Gorna Glogovitza Graben are the forth Tertiary zeolite rocks deposit in Western Bulgaria. Terrigenous and abiogenic (calcareous) lacustrine sedimentation in the Graben has been influenced of process(es) of acid ash pyroclastics deposition. Pyroclastic material constitutes of glass-shards, pumice fragments (with plagioclase, biotite, amphibole and scarce sanidine microphenocrysts), crystalloclasts and cognate phenorhyolitic-penorhyodacitic fragments. Glassy components have been completely transformed according to the following reactions' sequence: volcanic glass →clinoptilolite → analcime → K-feldspar. Such an authigenic silicate association formed in lacustrine environment is interpreted as characteristic of high salinity (about 50000 ppm) and high pH value (nearly 9.5) of the basin/pore wa-ter. The environments in which Gorna Glogovitza Graben and other Bulgarian and Serbian Tertiary analcime rocks were formed can be hardly compared. A suggestion about a similar environment of analcime formation in Gorna Glogovitza Graben and Slanci basin (near Belgrade, Serbia) can be made based on the very close cell parameters of the analcime (respectively a0 = 13.70980 A, cell volume = 2576.87 A3 and a0 13.699-13.707 A, cell volume - 2571-2575 A3)

    Reclaimed soils built in three main mining areas of Bulgaria - Maritsa East, Chukurovo and Asarel were studied. These soils are characterized by low total content of Pb and Zn and high total copper content in Asarel's soils. The copper content in these soils exceed more than three times the limit concentrations regulated by the Bulgarian legislation and significantly increased joint toxicity of studied metals (pollution index ranging from 1.3 to 1.9). The maximum content of exchangeable forms of lead determined in 1 M NH4NO3 and 1 M NH4Ac is 30.5 μg/g or 19% of the total lead content - 47.7 μg/g or 9.4% of the total copper content and zinc - 73.5 or 13.3%. Lead is nonspecifically adsorbed by soluble (extractable) fraction of organic matter (humic and fulvic acids, R2 = 0.995), silt fractions (particle size 0,01 - 0,005, R2 = 0.999 or 0.005 - 0.001 mm) and their complexes with organic matter - evidenced by the high correlations between the content of soluble (extractable) fraction of organic matter and content of silt fractions (R2 = 0.792). Copper in natural soils is dominantly nonspecifically adsorbed by organic matter and clay minerals, which is not typical for all studied reclaimed soils. The strong affinity of copper to the organic matter was observed only in cases when humic acids are highly condensed aromatic compounds, associated with calcium. Exchangeable zinc also shows a strong correlation with organic matter and a minor with different soil mechanical fractions.

  11. Wavelet analysis on transient behaviour of tidal amplitude fluctuations observed by meteor radar in the lower thermosphere above Bulgaria

    Directory of Open Access Journals (Sweden)

    D. Pancheva

    Full Text Available On the basis of bispectral analysis applied to the hourly data set of neutral wind measured by meteor radar in the MLT region above Bulgaria it was demonstrated that nonlinear processes are frequently and regularly acting in the mesopause region. They contribute significantly to the short-term tidal variability and are apparently responsible for the observed complicated behavior of the tidal characteristics. A Morlet wavelet transform is proposed as a technique for studying nonstationary signals. By simulated data it was revealed that the Morlet wavelet transform is especially convenient for analyzing signals with: (1 a wide range of dominant frequencies which are localized in different time intervals; (2 amplitude and frequency modulated spectral components, and (3 singular, wave-like events, observed in the neutral wind of the MLT region and connected mainly with large-scale disturbances propagated from below. By applying a Morlet wavelet transform to the hourly values of the amplitudes of diurnal and semidiurnal tides the basic oscillations with periods of planetary waves (1.5-20 days, as well as their development in time, are obtained. A cross-wavelet analysis is used to clarify the relation between the tidal and mean neutral wind variability. The results of bispectral analysis indicate which planetary waves participated in the nonlinear coupling with the atmospheric tides, while the results of cross-wavelet analysis outline their time intervals if these interactions are local.

    2014-05-01

    Full Text Available The spatial pattern and epidemiology of backyard pig farming and other low bio-security pig production systems and their role in the occurrence of classical swine fever (CSF is described and evaluated. A spatial Bayesian model was used to explore the risk factors, including human demographics, socioeconomic and environmental factors. The analyses were performed for Bulgaria, which has a large number of backyard farms (96% of all pig farms in the country are classified as backyard farms, and it is one of the countries for which both backyard pig and farm counts were available. Results reveal that the high-risk areas are typically concentrated in areas with small family farms, high numbers of outgoing pig shipments and low levels of personal consumption (i.e. economically deprived areas. Identification of risk factors and high-risk areas for CSF will allow to targeting risk-based surveillance strategies leading to prevention, control and, ultimately, elimination of the disease in Bulgaria and other countries with similar socio-epidemiological conditions.

    Leptospirosis, a zoonotic disease that is caused by many serovars which are more than 200 in the world, is an emerging worldwide disease. Accurate and rapid diagnostic tests for leptospirosis are a critical step to diagnose the disease. There are some commercial kits available for diagnosis of leptospirosis, but the obscurity of a species- or genus-specific antigen of pathogenic Leptospira interrogans causes the reduced sensitivity and specificity. In this study, the polysaccharide derived from lipopolysaccharide (LPS) of nonpathogenic Leptospira biflexa serovar patoc was prepared, and the antigenicity was confirmed by immunoblot and enzyme linked immunosorbent assay (ELISA). The performance of the rapid diagnostic test (RDT) kit using the polysaccharide as a diagnostic antigen was evaluated in Korea, Bulgaria and Argentina. The sensitivity was 93.9%, 100%, and 81.0% and the specificity was 97.9%, 100%, and 95.4% in Korea (which is a rare region occurring with 2 serovars mostly), Bulgaria (epidemic region with 3 serovars chiefly) and Argentina (endemic region with 19 serovars mainly) respectively. These results indicate that this RDT is applicable for global diagnosis of leptospirosis. This rapid and effective diagnosis will be helpful for diagnosis and manage of leptospirosis to use and the polysaccharide of Leptospira may be called as genus specific antigen for diagnosis.

  19. Contrasting response of accessory ilmenite and magnetite to magma mixing and postmagmatic alteration in Petrohan pluton, Western Balkan, Bulgaria

    International Nuclear Information System (INIS)

    Series of representative samples of granodiorite, diorite, hybrid diorite, hybrid gabbro and mafic magmatic enclaves (MME) from Petrohan pluton, Western Balkan, Bulgaria, were chosen to clarify the effects of magma mingling and mixing and postmagmatic alteration onto the chemical composition, microstructure and stability of accessory magnetite and ilmenite. Although the two oxide phases were found to crystallize simultaneously – after and, probably, during the mixing of magmas as late magmatic minerals, they demonstrated much contrasted behaviour during magmatic and postmagmatic processes. In all the studied rocks, magnetite occurs in the form of well-preserved homogeneous crystals with sporadic, very fine exsolutions of ulvöspinel and coarser oxy-exsolutions of ilmenite. The microstructure of accessory ilmenite in the rocks is more complicated, being a result of several post-magma-mixing processes: (i) prevailing part of the ilmenite grains has relic outlook due to intensive replacement by late-magmatic and postmagmatic titanite; (ii) each ilmenite grain contains numerous micro- and nanoscale hematite exsolutions distributed parallel to (0001) crystallographic plane of ilmenite; (iii) significant part of the ilmenite grains is locally decomposed into hematite and rutile as a result of postmagmatic oxidation alteration. Magnetite from different rocks does not show any essential differences in its chemical composition: the most important minor elements in the mineral as Al, Ti and V vary in similar ranges (Al2O3 -0.3–0.9 wt.%, TiO2 – 0.5–1.4 wt. %, V2O3 – 0.1–0.45 wt. %). The composition of ilmenite grains (point analyses of ilmenite and area analyses of ilmenite with hematite exsolutions) is more variable and reflects effects of magma mixing – similar range of Fe3+ content (5–18 mol.% of Fe2O3) and anomalously high content of Mn (∼40 mol.% of MnTiO3) in part of ilmenite grains of hybrid diorite as well as the specific influence of the chemical

  3. An innovative view to the seismic hazard from strong Vrancea intermediate-depth earthquakes: the case studies of Bucharest (Romania) and Russe (Bulgaria)

    International Nuclear Information System (INIS)

    An advanced procedure for ground motion modelling, capable of synthesizing the seismic ground motion from basic understanding of fault mechanism and seismic wave propagation, is applied to compute seismic signals at Bucharest (Romania) and Russe, NE Bulgaria, due to the seismic hazard from intermediate-depth Vrancea earthquakes. The theoretically obtained signals are successfully compared with the available observations. For both case studies site response estimates along selected geological cross sections are provided for three recent, strong and intermediate-depth, Vrancea earthquakes: August 30, 1986 and May 30 and 31, 1990. The applied ground motion modelling technique has proved that it is possible to investigate the local effects, taking into account both the seismic source and the propagation path effects. The computation of realistic seismic input, utilising the huge amount of geological, geophysical and geotechnical data, already available, goes well beyond the conventional deterministic approach and gives an economically valid scientific tool for seismic microzonation.

    In the forty years since the war, things have been going gradually but progressively better for Bulgaria. An industry has been built up. As a tourist country, Bulgaria attracts millions of visitors from abroad every year. The Bulgarian agriculture has managed to overcome its hereditary malaise, the fragmentation of the arable land into small and tiny holdings. Environment burdens, soil erosion, air and water pollution are consequences of industrialization and socialistic agriculture. It is faire to speak of a conscious environmental policy in the case of Bulgaria only since the later half of the 60s. It was at that time that scientists first documented the deleterious side effects of industralization, and the State passed the first laws aimed at protecting the environment. In the 70s, environmental conservation in Bulgaria was institutionalized in bewildering multiplicity: the Legislative (National Assembly), the Executive (Government), the ''State Council'' (as a hybrid form of Legislative and Executive combined), and the umbrella organization ''Patriotic Front'' each set up their own bodies and institutions to be responsible for environmental conservation. Since 1977, the ''Environmental Protection Committee'' in the Council of Ministers has been acting as the supreme organ of control in this field. In the present-day ecology discussion there are a number of new and quite promising approaches - for example the ''agroecological brigades'' in the agriculture, a kind of ecological ''task force'', by which the party leadership, in particular, places great hopes for the future.

    consideration in plans for succession to the throne. In the earlier period of Byzantine history, slightly different circumstances and views prevailed. That is why, owing to some specific circumstances, the emperor's daughters were sometimes depicted in the portraits of the imperial family. However, from the time of the Komnenoi when the medieval dynastic awareness finally asserted itself in Byzantium, the images of the emperor's female progeny practically vanished from the pictures of those who wielded supreme authority. The custom of omitting the figures of the emperors' daughters from the presentations of the ruling houses was also accepted and rather strictly obeyed for a long time in the portraiture of the neighbouring Orthodox Christian countries. In Serbia, this was disregarded only till just before the state collapsed, while in Bulgaria, exceptions to this rule were observed a little earlier. This was the result of accepting the ideological and iconographic models that were distinctive for the nobility, at the height of the feudal period. The images of daughters-in-law had always been omitted even more consistently than in the case of the figures of daughters in the monarchical presentations of the Byzantine and other Orthodox Christian rulers. As a rule, they were not depicted close to the image of the sovereign, even when they were the wives of the proclaimed and even crowned co-rulers, and successors to the throne. It is very probable that this custom survived into the Palaiologan era even though there are some signs that in Byzantium, this rule may have been disregarded in some cases. The figures of sovereigns' wives and sons had a significantly different status from the images of daughters and daughters-in-law. As a rule, they played an essential and customary role in the monarchical presentation because the rulers' wives and male successors had a stake in authority, in its transfer and succession. Still, it often happened that even wives and sons were omitted from

    The aim of this study was to evaluate the residues of heavy metals as an indicator of environmental pollution in internal organs of golden jackal (Canis aureus) from an agricultural region in Bulgaria. It was demonstrated that the golden jackal has high potential for specific accumulation of heavy metals, thus implying that this species may serve as a biological indicator of their presence in the agricultural regions, which it inhabits. The concentrations of the targeted elements (mean [mg/kg of dried tissue] ± SD) were respectively: Cu-57.62 ± 10.76; Zn-141.45 ± 11.33; Ni-0.28 ± 0.19; Co-0.46 ± 0.30; Pb-6.88 ± 1.67 and Cd-0.58 ± 0.16 in liver and Cu-17.67 ± 5.01; Zn-58.28 ± 10.81; Ni-0.51 ± 0.4; Co-0.52 ± 0.29; Pb-4.03 ± 1.32 and Cd-1.41 ± 0.22 in kidney samples. The concentrations we found revealed the specific accumulation of these metals in golden jackal and provide values, within which negative effects on the advancement of its populations should not be expected.

    The horse-chestnut leaf miner, Cameraria ohridella, is an invasive alien species defoliating horse-chestnut, a popular ornamental tree in Europe. This paper presents quantitative data on mortality factors affecting larvae and pupae of the leaf miner in Switzerland and Bulgaria, both in urban and forest environments. Two sampling methods were used and compared: a cohort method, consisting of the surveying of pre-selected mines throughout their development, and a grab sampling method, consisting of single sets of leaves collected and dissected at regular intervals. The total mortality per generation varied between 14 and 99%. Mortality was caused by a variety of factors, including parasitism, host feeding, predation by birds and arthropods, plant defence reaction, leaf senescence, intra-specific competition and inter-specific competition with a fungal disease. Significant interactions were found between mortality factors and sampling methods, countries, environments and generation. No mortality factor was dominant throughout the sites, generations and methods tested. Plant defence reactions constituted the main mortality factor for the first two larval stages, whereas predation by birds and arthropods and parasitism were more important in older larvae and pupae. Mortality caused by leaf senescence was often the dominant mortality factor in the last annual generation. The cohort method detected higher mortality rates than the grab sampling method. In particular, mortality by plant defence reaction and leaf senescence were better assessed using the cohort method, which is, therefore, recommended for life table studies on leaf miners.

  14. The World Bank mission in Bulgaria with the objective of estimating the possibility to increase the safety of the Kozloduy NPP

    International Nuclear Information System (INIS)

    This is a report of the World Bank mission in Bulgaria held from 22 March to 31 April 1992. The author considers the present state of the safety level of all Kozloduy NPP reactors with emphasis of the units 1-4 which are of the WWER-440/230 type. Three main factors are discussed in detail: 1) design inherent safety; 2) equipment protection from accidental events connected with the equipment quality; 3) quality and culture of operation and quantitative evaluation of the safety. The areas requiring special attention in view of the safety enhancing are: safety goal policy; creation of national safety culture; planning and implementation of the improvement programme; assuring the equipment reliability; updating and protection the existing systems; furnishing the plant with new systems. A review of all on-going and proposed projects of the national authorities, IAEA, EC, WANO and BEQE is made. Some remarks are given also about the WWER-1000 type units 5 and 6. The estimated cost of all necessary measures for equipment improvement is $100-200 million and of the annual investment after the main reconstruction and innovation of the reactors - about $10 million which should be included in the normal operational expenses of the plant. A new approach to the responsibility role of the Bulgarian specialists should be created. A new and well grounded proposal for modifications in the equipment should be made from the National Electrical Company including economical evaluations. Another expert assessment will be requested from the foreign banks before financing

    Full Text Available The assessment of the threats in the “Stara Reka” reserve and its adjacent subalpine and alpine areas is important since it makes it possible the appropriate conservation measures to be taken in order to prevent or reduce the negative effects on the biodiversity and habitats. The assessment was based on systematic studies and visits in the “Stara Reka” Reserve, located within National Park “Central Balkan” (Bulgaria, during spring, summer and autumn seasons of 2010-2011. A number of threats were recorded, where those by anthropogenic origin were predominating. Tourists have negatively influenced the wild plants such as Allium ursinum, Inula helenium and Primula frondosa by picking them up. Damages were registered on the information system and signs. Waste disposal, fires, poaching and illegal fishing were also some of the recorded threats. Many natural succession changes quite dynamically vary the habitats in the reserve, but the most dangerous for the biodiversity and degradation of habitats remain fires, erosion and introduction of alien species.

    Full Text Available This paper discusses the unjustified assignment (based on calcareous nannofossils of a large portion of the Maastrichtian strata in the Mezdra and Lyutidol synclines (West Fore Balkan, Bulgaria to the Paleogene. The co-occurrence of Paleocene nannofossils, reported by some authors, and Maastrichtian macrofossil taxa in these sections indicates diachronism in the appearance of macro- and nannofossils across the K/Pg boundary. Thus, this boundary cannot be precisely localized except if the Maastrichtian fossils are assumed to have been redeposited, but there is no evidence of resedimentation. Maastrichtian macrofossils are found not only within the range of the Paleogene nannofossil zones, but also in sections overlying them in the Kajlâka Formation where new Maastrichtian macrofossil taxa, such as the echinoid Hemipneustes striatoradiatus (LESKE, appear and some inoceramid and cephalopod taxa range into this unit. These facts shed doubt over the applicability of nannofossils in determining the K/Pg boundary where this has already been firmly documented by macrofauna.

  17. A parametric analysis of the seismic input at the NE Bulgaria (Russe site) due to recent Vrancea intermediate-depth earthquakes

    International Nuclear Information System (INIS)

    An analytical deterministic technique, based on the simultaneous account of the fault mechanism and seismic wave propagation, has been applied to generate synthetic seismic signals at Russe, NE Bulgaria due to the strongest intermediate-depth Vrancea earthquakes, which occurred during the last century (1940, 1977, 1986 and 1990). The computations have been validated by comparison with the available observations, i.e. accelerograms and macroseismic intensity data. The synthetic signals have been generated varying the seismic source moment tensor and the Vp/Vs ratio of the uppermost layers along the investigated profile. Response and energetic spectra are calculated for the whole synthetic signals set. The obtained results show that all ground motion components give a significant contribution to the seismic input and that they can be influenced in similar degree by the investigated parameters. Therefore the seismic input (also at remote distances), should consider enough earthquake scenarios, and can be constructed via waveform modelling, considering all possible factors influencing the ground motion

The study was carried out at three sites located along a pollution gradient. An unpolluted region, the Strandzha Natural Park was used as a background region. MANOVA analysis revealed significant differences by species (F=9.61, p=0.003, site (F=24.12, p=0.0001 and exposure (F=3.79, P=0.013 effects. Significant increase of Pb and Cd bioaccumulation was found along the pollution gradient. Cd and Pb mean concentrations were highest at the site closest to the smelter and decreased with increasing the distance from them. The bioaccumulation of Pb was significant highest in the individuals of the yellow-necked mouse, followed by Mediterranean mice and common voles, whereas the common voles accumulated more Cd in comparison with the yellow-necked-, and Mediterranean mice. However, there is little evidence of adverse cadmium-mediated effects in yellow-necked- and Mediterranean mice and this species may be tolerant to Cd exposure. High Cd concentrations in body organs may simply reflect an ability to store the metal in a nontoxic, metallothionein-bound state. Liver Pb and Cd concentration did not differ significantly among sexes.

    Full Text Available Life cycle of the orphnine scarab beetles genus Chaetonyx was recorded for the first time based on the multiyear observations on the populations of its type species, Ch. robustus Schaum, 1862, in riverside habitats at Zemen Gorge region, South-Western Bulgaria. Our observations showed that this geobiont species is common in alluvial soils near Struma River, where it forms large colonies. At the Zemen Gorge, its preferable habitats are sparse riverside forests of Alnus glutinosa L. and Populus nigra L. neighboring grass communities. Larvae, adults and pupae were found up to 50 cm deep with most specimens inhabiting the upper soil layer from 0 to 20 cm deep. The highest recorded density was 89 adults and 581 larvae per 0.25 m2. Oviposition, hatching of the eggs, pupation and emergence of the new adults occur during the summer. Eggs have been found in surface soil layer in July and August, the pupae – mainly in July and August. Larvae of different instars were found in soil during all months of the study period. Adults from the new generation first occur in the beginning of August. In August, September and October adults from different generations can be found together. The main part of the adults seems to die after the reproduction period, and the common lifespan of adults seems to be about a year only. The life cycle of Ch. robustus in investigated habitat seems to be perennial and includes two years as larval stage and one as adult. Tropical Orphninae occupy a number of ecological niches but lack colonial geobiont specialists similar to Chaetonyx.

  20. Formation of ferrian chromite in podiform chromitites from the Golyamo Kamenyane serpentinite, Eastern Rhodopes, SE Bulgaria: a two-stage process

    The Golyamo Kamenyane serpentinite is a portion of a metaophiolite, located in the Upper High-Grade Unit of the metamorphic basement of the Eastern Rhodope Metamorphic Complex, SE Bulgaria. It consists of metaharzburgite and metadunite hosting layers of metagabbro and some chromitite bodies. All these lithologies were affected by ultrahigh-pressure (UHP) metamorphism and subsequent retrograde evolution during exhumation. Chromite from chromitites can be classified into four textural groups: (1) partly altered chromite, (2) porous chromite, (3) homogeneous chromite and (4) zoned chromite. Partly altered chromite shows unaltered, Al-rich cores with unit cell size of 8.255 Å and Cr# [Cr/(Cr + Al) atomic ratio] = 0.52-0.60, Mg# [Mg/(Mg + Fe2+) atomic ratio] = 0.65-0.70 and Fe3+/(Fe3+ + Fe2+) = 0.20-0.30, surrounded by porous chromite, with a cell size of 8.325 Å, Fe3+/(Fe3+ + Fe2+) talc and magnesiohornblende. Mineral data and thermodynamic modeling allow interpretation of the alteration patterns of chromite as the consequence of a two-stage process developed during retrograde metamorphic evolution coeval with fluid infiltration. During the first stage, chromite reacts in the presence of fluid with olivine to produce chlorite and Cr- and Fe2+-rich residual chromite (ferrous chromite) at ~700 to ~450 °C. This dissolution-precipitation reaction involves continuous chromite mass loss resulting in the development of a porous texture. This stage takes place progressively on cooling under water-saturated and reducing conditions. The second stage mainly consists of the formation of homogeneous chromite with ferrian chromite composition by the addition of magnetite to the porous ferrous chromite during a late oxidizing hydrothermal event.

Rapid molecular methods for the analysis of highly pathogenic bacteria have been developed for monitoring quality. Mycobacterial species can be isolated from waste, surface, recreational, ground and tap waters and human pathogenicity of nontuberculose mycobacteria (NTM is well recognized. The objective of our study was to perform molecular analysis for key-pathogens, with a focus on mycobacteria, in water samples collected from the Black Sea and the Dam of Iskar. In a two year period, 38 water samples were collected—24 from the Dam of Iskar and 14 from the Black Sea coastal zone. Fifty liter water samples were concentrated by ultrafiltration. Molecular analysis for 15 pathogens, including all species of genus Mycobacterium was performed. Our results showed presence of Vibrio spp. in the Black Sea. Rotavirus A was also identified in four samples from the Dam of Iskar. Toxigenic Escherichia coli was present in both locations, based on markers for stx1 and stx2 genes. No detectable amounts of Cryptosporidium were detected in either location using immunomagnetic separation and fluorescence microscopy. Furthermore, mass spectrometry analyses did not detect key cyanobacterial toxins. On the basis of the results obtained we can conclude that for the period 2012–2014 no Mycobacterium species were present in the water samples. During the study period no cases of waterborne infections were reported.

  2. Uranium industry in Bulgaria and environment: Problems and specific features of the period of the technical close-out and remediation of the negative consequences

    International Nuclear Information System (INIS)

    The uranium industry in Bulgaria started immediately after the II World War with classical underground mining and hydrometalurgical processing of the ore to uranium concentrate. Up to 1958 no tailings pond existed at the Bukhovo plant and the result is 1.2 x 106 square meters contaminated with radium land along the rivers Yanishtitsa and Lesnovska. In the process of mining approximately 300 heaps of low grade ore and sterile rock and three tailing ponds were generated mainly in the southern part of the country. Along the valleys of the rivers Maritsa, Tundzha and Struma approximately 15 low grade ore deposits were processed by in-situ leaching with sulphuric acid. The surface communications (tubes) cover approximately 1.6x107m2 agricultural land and forests. Some of the heaps of the underground mines have been processed by combined in-situ leaching technologies. Almost no preventive or counter measures have been implemented during the whole period of operation for preservation of water, soil and air from mechanical, chemical and radioactive pollution. Therefore in the period of the close-out of the uranium industry a programme has been developed for remediation procedures which includes assessment of the status of the environment, prognoses for the influence of the uranium sites on the region, technical projects for cleaning facilities and remediation procedures. For each case, depending on the type and the level of contamination, the specific optimal ecological solutions have the purpose of reasonable minimization of the risk at minimum cost. In the present work estimations and predictions for the underground and surface waters and surface contamination for several typical uranium sites are discussed. (author). 8 refs, 4 tabs

    Full Text Available The rich orthophragminid assemblages from the upper Thanetian and lower Ypresian of Turkey are discussed together with the coeval faunas from Spilecco (N Italy and Beloslav (Bulgaria. Their taxonomy, evolution and biozonation in the Western Tethys are revised. Our biometric study is based mainly on a large number of equatorial sections of megalospheric individuals. We present the emended description of Discocyclina seunesi, D. tenuis, Orbitoclypeus multiplicatus, O. bayani and Asterocyclina taramellii. A new species, Nemkovella stockari is introduced. The evolutionary lineages of Discocyclina seunesi, Orbitoclypeus multiplicatus and O. bayani are restored for the first time by using the consistent size-increase of the megalospheric embryon that also allowed introducing some new subspecies (Discocyclina seunesi beloslavensis, D. s. karabuekensis, Orbitoclypeus multiplicatus kastamonuensis, O. bayani kurucasileensis and O. munieri ponticus. By owing the most complete record of Thanetian and early Ypresian orthophragmines from the Western Tethys (using also data from SW France and the Crimean Peninsula we could reconstruct their early evolution. The chronostratigraphical position of some localities was ascertained from planktic and larger benthic foraminifera, as well as calcareous nannoplankton. In the updated orthophragminid zonation (zones are marked by OZ, OZ 1a corresponds to the early Thanetian, OZ 1b to the middle Thanetian. They are distinguished on the base of the evolution of Discocyclina seunesi. In these zones, only two unribbed species of Discocyclina and Orbitoclypeus each are present. Ribbed Orbitoclypeus, genus Asterocyclina and Nemkovella appeared in the redefined OZ 2 zone belonging to the late Thanetian. Discocyclina archiaci and D. dispansa substituted D. seunesi at about the Paleocene/Eocene boundary. The early Ypresian can be subdivided into the OZ 3 and 4 zones that can be distinguished from each other by the different

    Full Text Available The author provides an overview of the main urban planning trends in the present-day Bulgaria. The author also demonstrates principal approaches to area planning and provides examples of master plans of major cities of the country. The author emphasizes the need to resolve the environmental problems of urban territories, to develop their public transportation networks, resorts, landscape gardening, and a special role of historic and archeological monuments in the present-day cities. Today, multiple hierarchically arranged plans of districts and towns are being developed in accordance with the Law on area arrangement of 2001. There are three levels of area planning in Bulgaria: strategic, tactical and operative/applied. The level of strategic planning covers the territory of the whole country (or its major parts, including regions and clusters of communities. The second level of area planning represents a tactical level. It is applied to smaller sections of the territory (communities, towns and it converts into more detailed planning of the territory if compared to the top level of area planning. The general structure of the territory is developed at this level of planning. This level includes master plans of cities and towns. The third level, the level of operative/ applied planning, is applied to separate parts of populated areas, even particular sites. This level is characterized by detailed elaboration and it serves as a link to architectural planning. This level incorporates detailed area plans.

    International Nuclear Information System (INIS)

    The Kozloduy NPP intranet portal was established in the late 1990s. The purpose of the portal was to provide access to general and frequently used information necessary for routine and daily work of the plant staff. Over the years the intranet site has been continuously improved and extended. The portal is now a standard tool for every member of plant personnel. The portal architecture has been designed on a modular basis and follows the general structure of the plant. The home page contains general, publicly accessible and frequently used information and corresponding links. Each major division maintains its own sub-portal, which services the specific needs of the division personnel. Hierarchical structure, pull down and shortcut menus facilitate navigation and provide a user friendly interface. The portal is based on FrameWork 1.1 and DotNetNuke and provides group and individual communications and data exchange. Most of the major plant databases related to documentation, plant operation, plant safety, plant systems data, training and human resources are accessible through the portal. Miscellaneous information and useful internal and external links also are available. Different types of communication services are organized through a separate server. Depending on their role and position, each staff member has been provided with an internal and/or external email address and an individually configured internet connection. For general purposes cable internet is accessible at several points, which are evenly located around the site, and there is also a secure wireless network connection. Search and retrieve functions are implemented through respective engines, which are incorporated into applications. The portal has a strongly defined access rights system. Anonymous access is prevented; page personalization is available only for limited specific cases. Figures show the home page and the path to Units 5 and 6 on-line technical parameters

  9. Neutron activation analysis in Bulgaria

    International Nuclear Information System (INIS)

    The development of instrumental neutron activation analysis (INAA) as a routine method started in 1960 with bringing into use of the experimental nuclear reactor 2 MW -IRT-2000. For the purposes of INAA the vertical channels were used. The neutron flux vary from 1 to 6x1012n/cm2s, with Cd ratio for gold of about 4,4. In one of the channels the neutron flux is additionally thermalised with grafite, in others - a pneumatic double-tube rabbit system is installed. One of the irradiation positions is equiped with 1 mm Cd shield constantly. With the pressure of the working gas (air) of 2 bar the transport time in one direction is 2,5 sec. Because of lack of special system for uniform irradiation an accuracy of 3% can be reached by use of iron monitors for long irradiations and copper monitors for use in the rabbit system. Two neutron generators are also working but the application of 14 MeV neutrons for INAA is still quite limited. The most developed are the applications of INAA in the fields of geology and paedology, medicine and biology, environment and pollution, archaeology, metallurgy, metrology and hydrology, criminology

  11. Natural gas industry in Bulgaria

    International Nuclear Information System (INIS)

    An overview of the Bulgarian natural gas industry is presented. The starting point was the discovery of the indigenous Chiren gas-field in 1967. The first agreement with the ex-USSR for supply of natural gas and construction of main pipelines was signed in 1968. The state gas company BULGARGAZ is responsible for transportation, storage, distribution, processing and marketing of the gas to over 150 industrial companies in the country, as well as for the transportation services to gas importers in neighboring Turkey. The GAZSTROJMONTAZH company accomplish the construction of the local and transit pipelines to Turkey and Greece, as well as of some objects in Iran, Syria, Ukraine and Germany. In the past 20 years, 87890 million m3 natural gas from Russia are supplied and 846 million m3 - from domestic sources. The share of natural gas in the overall energy balance is 13.6% for 1992. The restructuring and further development of gas industry require to take into account some factors as: security in supply; investments for technical assurance; pricing policy for natural gas; development of private business.

    Post-collisional (56.0-40.4 Ma) adakitic magmatism in the Rhodope Massif and the Kraishte region, including W. Srednogorie, in South Bulgaria followed the collision of the Rhodope and Pelagonian Massifs. It forms a 250 km NW trending belt which continues into the 1000 km long belt of Eocene magmatism in northern Turkey and Iran. The rocks are represented by felsic subvolcanic dykes and sills in the Kraishte and plutons in the Rhodopes. Here, we synthesize new chemical (whole-rock major and trace elements, and Sr and Nd isotopes) and LA-ICP/MS mineral and U-Pb zircon age data along with published similar data in order to constrain the genesis of this magmatism and the early Cenozoic geodynamic evolution of the central Balkan Peninsula. The rocks display typical subduction-related characteristics with enrichment in LILE and LREE and depletion in HFSE (Nb, Ta and Ti). In the Kraishte and western Srednogorie Zones these are calc-alkaline to high-K calc-alkaline rhyolites, displaying a typical adakitic signature, i.e. high La/Yb and Sr/Y ratios. The studied Rhodope Massif rocks are predominantly high-K calc-alkaline and subordinate calc-alkaline granites and granodiorites with a minor amount of tonalites. Petrographically, they are H2O- and accessory-rich (allanite, epidote, titanite, apatite) rocks, showing geochemical affinities from non-adakitic tonalites and mafic granodiorites to adakitic granodiorites and granites. Similarity of Sr and Nd isotopic compositions of the Kraishte subvolcanic and Rhodope intrusive adakitic rocks with the neighboring and coeval NW Anatolian basaltic to dacitic volcanics and plutons suggests that the most likely source for the South Bulgarian adakitic rocks is the subduction-enriched depleted lithospheric mantle. The nearby and contemporaneous East Serbian alkaline basalts are isotopically and compositionally different and, probably, originate from an OIB-like mantle source. Subsequent fractionation within an isotopically similar lower

    New low-temperature thermochronological data have been used to quantify the protracted, Eocene-Miocene cooling histories of upper and lower plate rocks of the Kesebir-Kardamos extensional dome, Eastern Rhodopes, Bulgaria. 40Ar/ 39Ar and apatite fission-track data reveal that the lower plate has experienced continuous cooling and exhumation, since the Late Eocene. Muscovite 40Ar/ 39Ar plateau ages of 36.90 ± 0.16 Ma and 37.28 ± 0.19 Ma (2 σ) from metamorphic rocks of the footwall reveal the approximate time span during which they cooled below ˜ 350 °C during exhumation caused by detachment faulting. The sedimentary rock-hosted gold mineralization, which represents a thermal event at ˜ 250-220 °C, developed during the early stage of basin formation between 34.71 ± 0.16 Ma and 35.36 ± 0.21 Ma (adularia 40Ar/ 39Ar plateau ages; 2 σ). The termination of hydrothermal mineral deposition at Ada Tepe occurred contemporaneously with the earliest phase of calc-alkaline type magmatism at Iran Tepe (33.97 ± 0.36 Ma to 34.62 ± 0.46 Ma, hornblende and biotite 40Ar/ 39Ar plateau ages, 2 σ). Thermal history modelling of apatite fission-track data shows that the lower plate rocks cooled through ˜ 120 °C at ˜ 18.3 ± 1.9 Ma (1 σ). A time-temperature model obtained from zircon and apatite fission-track data from the upper plate reveals that it was being buried during the late Eocene. At ˜ 33-30 Ma, a dramatic change of the time-temperature path was caused by the initiation of horst-graben structures, resulting in rapid exhumation of the upper plate. Our new thermochronological data reveal many aspects of the mechanisms of formation of sedimentary rock-hosted gold deposits. The heat accumulated during sedimentary burial of the upper plate is a plausible heat source to drive hydrothermal fluid circulation and ore formation. The development of large half-graben basins in the hanging walls of detachment faults, accompanied by a favourable climate, may have created a

Other factors are hereditary, gender, body weight, food, psychological status, family relationships. Natural waters derived from various Bulgarian water springs, as well as melt water and blood serum of cancer patients between 50 and 70 years old were investigated by IR, NES and DNES-methods. We applied the NES- and DNES-methods for calculation of the average energy of hydrogen bonds (∆EH...O among H2O molecules in the samples, as well as the percent distribution of H2O molecules according to energies of hydrogen bonds within intervals (from -0.08 to -0.1387 eV.

For a group of people in critical condition of life and patients with malignant tumors the greatest values of local extremums in DNES-spectra are shifted to lower energies relative to the control group. The IR-spectrum of mountain water is most similar to the IR-spectrum of blood serum of healthy group of people with a local maximum at  = 8.95 m. Natural mountain and melt water with unique chemical composition and less deuterium content seems to be one of the most important factors for longevity. In Bulgaria, most long lived people and centenarians live in the Rhodope Mountains, while in Russia – in Dagestan and Yakutia. The similar characteristics possess mountain water from Teteven and other Bulgarian sources. There are new proofs for biophysical and biochemical effects of Ca2+, Mg2+, Zn2+ and Mn2+ in water.

The major direct thermal water use nowadays covers: balneology, space heating and air-conditioning, domestic hot water supply, greenhouses, swimming pools, bottling of potable water and geothermal ground source heat pumps (GSHP). The total installed capacity amounts to about 77.67 MW (excl. GSHP) and the produced energy is 1083.89 TJ/year. Two applications - balneology and geothermal ground source heat pumps show more stable development during the period of 2005 - 2010. The update information on the state-owned hydrothermal fields is based on issued permits and concessions by the state.

    After the turn to market oriented economy a lot of drugs were authorized for sale in the East European countries. Because of the limited resources of these countries, mainly generic or brand generic products were licensed. The number of the patented drugs on the market could be used as measure of the market attractiveness to the R&D producers. The study shows the analysis of the innovativeness of the Bulgarian drug market comparing the registration and the patient activity of the producers. The number of the authorized products for five years period (1990-2000) and share of the patented products were investigated. During the observed period the number of newly authorized pharmaceuticals increased almost seven times from 800 (650 INN) to 6000 (2000 INN) dosage forms. The prevailing part of the newly registered drugs was found to be brand generics and possess only trade name protection. The share of drugs that are patented is less than five percent of all newly registered medicines, and among the fifty most commonly prescribed and sold medicines between 1996-2000, only 0.5 percent of drugs were patented. Obviously the Bulgarian pharmaceutical market is very competitive but not that attractive for most of the R&D producers. In general the registration of the patent protected products is increasing during the years and especially after harmonization of the related legislation with the EU requirements. The patent activity of the pharmaceutical companies regarding newly authorized drugs is influenced by the structure of morbidity and population. During the last two years the patent activity is increasing and is oriented mainly towards the protection of newly authorized drugs or pharmaceutical forms and obligatory registration of trademarks for the privatized Bulgarian pharmaceutical manufacturers.

  8. Building energy partnership between Bulgaria and Austria

    International Nuclear Information System (INIS)

    The project of Energie Verwertungsagentur (EVA) studies the possibilities for partnership between the two countries with respect of background conditions. Energy Efficiency Funds in some Central and East European countries (CEEC) in the framework of the PHARE programme and in co-operation with the EBDR aimed at increasing the market penetration of Combined District Heating and Power (CHP) technologies are being formed. The proposed project includes establishment of a Competence Centre for CHP technologies promotion. The Programme for the promotion of energy efficiency investments foresees co-financing the existing energy-efficiency funds and promotion and support of so called Energy Service Companies (ESCOs) which invest into energy efficiency measures on their own and get re-financing from the cuts in the energy bills. Several surveys show the considerable potential for the use of renewable energy sources (RES) in some CEEC. Proposed projects, as well as creation of Promotion Centres for RES and its future tasks are discussed

  9. Quaternary Tectonics of The Vitosha Mountain (bulgaria)

    Science.gov (United States)

    Angelova, Dora

    The Vitosha Mt. is a Cretaceous paleovolcano of the central type with complex ge- ological evolution. From a contemporary point of view it has a marked orographic homogeneity, which is connected with its specific evolution during the Neogene and the Quaternary. At the background of intensive vault formation, graben systems from the Maritsa and Strouma fault zones originated in a sharp discordance along its pe- riphery. The vault formation process caused the accumulation of tectonic stresses in different parts of the Vitosha Mt. in the course of time and space. The tectonic stresses provoked the formation of concentric normal faults. Their surface display predeter- mined not only the block disintegration of the structure but also its primary relief. The active mountain formation of Vitosha was controlled by the Pernik and Vladaya fault zones, and by the Vitosha, Zheleznitsa, Matnitsa and Chuipetlovo fault beams during the Quaternary. The Pliocene-Pleistocene boundary was accompanied by active ver- tical tectonic deformations. As a result of pulse tectonic movements and subsequent deformations along the above mentioned structures, a global re-arrangement of the Vladaiska and Strouma River basins took place in the region of the Vladaya village and to the south of the Chuipetlovo village. The age of these events is 0.73 Ma. The pa- leoseismic dislocation in the region of the Dragalevtsi quarter was probably formed at the same time. The paleoseismic deformations during the Middle Pleistocene were es- tablished along the radial faults. They had caused rock-falls in the Douhlata cave, pyra- teries and bifurcations of the underground aquatic system and of the Klisuritsa River. The Holocene stage was characterised by intensified vertical movements along all fault structures together with the climatic changes under post-glacial circumstances. The Vitosha paleovolcano was mightily raised due to the vertical compression and new river system originated while the old one was rotated in a counter-clockwise di- rection. The peat bogs were formed in the nodes between the concentric and radial fault structures and as a result of paleoearthquakes. The performed dating proves that the time of their manifestation was between 500±50 years, the beginning of this process being about 6000 B.P. The orographic ridge of the Vitosha pluton was disturbed due to a paleoearthquake in the Cherni Vruh region in 705+-65 B.P.

    Full Text Available The necessity of improving the forecasts accuracy grew in the context of actual economic crisis, but few researchers were interested till now in finding out some empirical strategies to improve their predictions. In this article, for the inflation rate forecasts on the horizon 2010-2012, we proved that the one-step-ahead forecasts based on updated AR(2 models for Romania and ARMA(1,1 models for Bulgaria could be substantially improved by generating new predictions using Monte Carlo method and bootstrap technique to simulate the models' coefficients. In this article we introduced a new methodology of constructing the forecasts, by using the limits of the bias-corrected-accelerated bootstrap intervals for the initial data series of the variable to predict. After evaluating the accuracy of the new forecasts, we found out that all the proposed strategies improved the initial AR(2 and ARMA(1,1 forecasts. These techniques also improved the predictions of experts in forecasting made for Romania and the forecasts of the European Commission made for Bulgaria. Our own method based on the lower limits of BCA intervals generated the best forecasts. In the forecasting process based on ARMA models the uncertainty analysis was introduced, by calculating, under the hypothesis of normal distribution, the probability that the predicted value exceeds a critical value. For 2013 in both countries we anticipate a decrease in the degree of uncertainty for annual inflation rate. || La necesidad de mejorar la precisión de las previsiones ha crecido en el contexto de crisis económica actual, pero son pocos los investigadores que se habían interesado hasta ahora por la búsqueda de estrategias empíricas para mejorar sus predicciones. En este artículo, a través de las previsiones de la tasa de inflación en el horizonte 2010-2012, hemos podido comprobar que las previsiones de un solo paso adelante sobre la base de modelos actualizados AR(2 para Rumanía y ARMA(1

    Prior to World War II, the majority of Bulgarian farms were very small, fragmented, and produced predominantly for their own consumption. By 1989, however, Bulgarian agriculture was organized in large-scale, mechanized farms, producing for national and international consumption. Many observers expected further radical changes after 1989, with wide-spread distribution of property rights in land, and market liberalization, leading to the emergence of western-style family farms.In this paper, we...

  13. Trends for the development of nuclear medicine in Bulgaria

    International Nuclear Information System (INIS)

    Full text: A great advantage of the NM methods is a possibility to visualize the early changes of the organ's function. Nowadays there is a global increase of the numbers of NM diagnostic and therapy procedures, predominantly for the sake of the quickly growing of the multimodality imaging method PET/CT for diagnosis, staging and therapy effect in oncological and benign diseases. In our country after a period of a decrease of the number and range of NM investigations, because of the competition with other imaging methods and financial reasons, a tendency of increase of clinical interest to these entirely functional methods is registered. A great contribution for this has an installation of 4-5 new gamma cameras recently with new diagnostic possibilities and winning recognition of radionuclide therapy. What have to be our activities in order NM in our country to take an appropriate place? The tendency for installation of new gamma cameras has to continue including PET/CT. Growing application of the NM therapy has to continue, especially in refractory to conventional therapy diseases. An increase specificity of NM diagnostic methods has to be followed, applying more specific radiopharmaceuticals, including those for receptor imaging. Young, educated, motivated professionals has to be created who will introduce and recognize new diagnostic and therapy NM methods

  17. Radio-sensitivity of spruce population progeny in Bulgaria

    International Nuclear Information System (INIS)

    The radio-sensitivity of Picea abies (L.) Karst populations was investigated by comparing the effect of acute irradiation with different Co-60 rates on seed germination and the survival of the seedlings obtained from them. Spruce stands in the Rila, Pirin and Rhodopes, the Balkan, Vitosha and Ossogovo mountains have been studied at 1000 to 2000 m alt. into 200-300 m intervals. The seed material collected from them by individual trees, altitude belts and mountains has been irradiated with 200 krad, 500 krad, 1000 krad, 1500 krad and 7500 krad. The germination capacity of the seeds was calculated in technical germination, absolute germination, germination energy and seed dormancy, while the post-irradiation effect was established in accordance with the survival rate of the seedlings for one- and two-year periods in greenhouses on a sand substrate. Radio-sensitivity of every spruce population depended on its vitality and Vigour. The spruce population in the Rhodope Mountains exhibits highest radio-hardiness, followed by those in the Rila, Central Balkan, Pirin, Vitosha and Ossogovo mountains. Irradiation with 200 krad, and in certain cases with 500 krad, showed a stimulation effect on germination of spruce seeds and the survival rate of the seedlings. LD-50 for spruce seeds, taking into account one- and two-year-old seedlings, was within the 500 to 1000 krad range. (author)

    Full Text Available Propolis shows biological properties such as antibacterial action. This bee product has a complex chemical composition, which depends on the local flora where it is produced. Salmonella serovars are responsible for human diseases that range from localized gastroenteritis to systemic infections. The aim of the present study was to investigate the susceptibility of Salmonella strains, isolated from food and infectious processes, to the antibacterial action of Brazilian and Bulgarian propolis, as well as to determine the behavior of these bacteria, according to the incubation period, in medium plus propolis. Dilution of ethanolic extract of propolis in agar was the used method. Brazilian and Bulgarian propolis showed an antibacterial action against all Salmonella serovars. The minimal inhibitory concentrations (MIC of propolis were similar, although they were collected in different geographic regions. Salmonella typhimurium, isolated from human infection, was more resistant to propolis than Salmonella enteritidis.
