    1983-04-01

    This discussion of Bulgaria focuses on the following: geography; the people; history; government; political conditions; the economy (economic reforms and plans, industry and agriculture, and trade); foreign relations; and relations between the US and Bulgaria. The population in December 1980 numbered 8,876,652; the annual growth rate was 3.6/1000. The infant mortality rate was 20.2/1000 with life expectancy 69 years for men and 74 years for women. Bulgaria, which is located on the Balkan Peninsula, extends from the western shore of the Black Sea to Yugoslavia in the west. In the north, the Danube River is a common boundary with Romania. Greece and European Turkey lie to the south and southeast. Population density is 1 of the lowest in Eastern Europe, about 80 persons per square kilometer. More than half of the population lives in urban areas, compared to 1/3 in 1956. Bulgarian is the primary language spoken. Religious activity is discouraged by the Bulgarian communists. Education is free and compulsory to age 15. A fully independent Bulgarian kingdom was proclaimed September 22, 1908. Communist rule began September 9, 1944, when a communist dominated coalition, called the Fatherland Front, seized power from a coalition government formed to arrange an armistice with the Allies. The constitution stipulates that the Communist Party is the leading force in society and in the state. It also provides for a unicameral 400 member National Assembly. The Bulgarian Communist Party (BCP) controls all phases of Bulgarian life. Party organization parallels the government structure with a central apparatus at Sofia and subordinate organizations in provinces and communes. At the end of World War 2, Bulgaria was among the least industrialized European countries. Bulgaria's national income grew rapidly in the 1960s and early 1970s, but increased by only 5.7% in 1980, down from 6.5% in 1979. A major factor in Bulgaria's growth rate has been Soviet assistance.

  3. Chemical Education in Bulgaria

    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.

    Abstract The present checklist includes data on the species composition, geographic distribution and feeding preferences of thrips species in Bulgaria. In total, 155 species in 48 genera are listed. Of these, 125 species belong to suborder Terebrantia and include 103 species of 33 genera in family Thripidae, 14 species of two genera in Aeolothripidae, seven species of two genera in Melanthripidae and one species in Fauriellidae. In suborder Tubulifera, 30 species of 10 genera in the single family Phlaeothripidae are listed. Of the 155 Bulgarian thrips species, 87.7% are phytophagous, 4.5% are obligate predators, 5.8% are mycophagous and 1.9% are with unknown feeding preferences. Fourteen pest species are listed for Bulgaria, of which Frankliniella occidentalis, Thrips tabaci and Haplothrips tritici are of economic importance. The list provides detailed information on the horizontal and vertical distribution of Thysanoptera in 5 regions and 45 subregions of Bulgaria. The present paper also includes an evaluation of the biodiversity of Thysanoptera and the extent to which each region of the country has been studied. PMID:26019678

    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

  9. Circulation factors affecting precipitation over Bulgaria

    NASA Astrophysics Data System (ADS)

    Nojarov, Peter

    2017-01-01

    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.

    Introduction Outbreaks of the zoonotic disease tularemia occurred in north-east Bulgaria in the 1960s. Then came 30 years of epidemiological silence until new outbreaks occurred in west Bulgaria in the 1990s. To investigate how bacterial strains of Francisella tularensis causing tularemia in wildlife and humans in the 1960s and the 1990s were related, we explored their genetic diversity. Material and methods Ten F. tularensis genomes from the 1960s (n=3) and the 1990s (n=7) were sequenced, assigned to canonical single-nucleotide polymorphism (canSNP) clades, and compared to reference genomes. We developed four new canSNP polymerase chain reaction (PCR) assays based on the genome sequence information. Results and discussion The genetic analysis showed that the outbreaks in the 1960s as well as in the 1990s involved multiple clones and new genetic diversity. The smallest genetic difference found between any of the Bulgarian strains was five SNPs between the strains L2 and 81 isolated 43 years apart, indicating that F. tularensis may persist locally over long time periods without causing outbreaks. The existence of genetically highly similar strain-pairs isolated the same year in the same area from different hosts supports a hypothesis of local expansion of clones during outbreaks. Close relationship (two SNPs) was found between one strain isolated 1961 in northeast Bulgaria and one strain isolated 5 years before in USSR. Historical data coinciding with the actual time point describe the introduction of water rats from USSR into the Bulgarian outbreak area, which may explain the close genetic relationship and the origin of the outbreak. Conclusion Genome analysis of strains from two outbreaks in the 1960s and the 1990s provided valuable information on the genetic diversity and persistence of F. tularensis in Bulgaria. PMID:27790972

    Koleva, Vesselina; Georgiev, Iliya

    Wooden calendars are a specific tool for preserving the church calendar in medieval Europe. The Christian symbols are skillfully interwoven with traditional signs, which mark the days of importance for the economic and ritual life in a year. The archaic method of time reckoning has turned into a tool for disseminating and establishing the Christian festival system, and is one of the proofs of the syncretism between the pagan tradition and the new religious ritualism. Bulgarian Christians used such objects until the beginning of the 20th century. The earliest date fixed on a wooden calendar is 1783. These calendars are also called rabosh in Bulgaria. The calendar presented here is based on the Julian (solar) calendar containing the major fixed feasts of the Orthodox Church. It has not been published so far and is kept in a private collection.

    Over the past decade new ecological indices based on phytoplankton and macrophytes were developed as part of the tools for assessment of the ecological status of water bodies. This study demonstrates the applicability of two of them (Assemblage index /Q/ and Algae Group Index /AGI/) for evaluation of water bodies from a lake type L4 as well as their comparability. Assessment of the ecological status of two lake ecosystems was performed in order to ensure successful protection, enhancement and management of lowland and semi-mountain lakes in Bulgaria. Data on the aquatic flora from Golyamo Skalensko Lake and Malko Skalensko Lake over a period of two years were used to assess their ecological status. In addition, the toxic potential of the established dominant cyanoprokaryotic species was also evaluated. Phytoplankton- and macrophyte-based metrics resulted in complementary evaluation of temporary and long-term environmental conditions. Despite the hydraulic connection and proximity between the two lakes, Golyamo Skalensko Lake and Malko Skalensko Lake appear as completely different ecosystems, according to the phytoplankton structure (species composition, number of species, abundance, seasonal succession), macrophytes and ecological status.

    The oil- and gas-prospective areas in northern and southeastern Bulgaria and the adjacent regions on the Black Sea shelf are accepted as a part of the Carpatho-Balkan oil- and gas-bearing province. The peculiarities of the tectonic structures are conditioned by some specific, mostly collision processes during the Paleozoic, Mesozoic, and Tertiary. They are deciphered now with the help of the depth seismic explorations, and magnetotelluric, thermal, gravimetric, and magnetic data, in combination with geological mapping of south Bulgaria. The usual type of seismic data and well control as well exist in north Bulgaria and the Black Sea shelf zone; parts of this information has been published. Now an attempt is made for general overview of the three regions built by some parts of the Moesian platform; ForeBalkan, Balkan, and Srednogorie region; and the western part of the Black Sea megadepression, as well. Prospects of the Mesozoic and Tertiary sediments in north Bulgaria have been comparatively well studied, but questions remain for southeastern Bulgaria and the Black Sea shelf zone, coming from unresolved problems concerning the geological structure. Future regional exploration is expected to discover new deposits in the reef trends of Paleozoic, Triassic, and Late Jurassic-Valanginian age, and connected with usual local Tertiary and Mesozoic structures and vast overthrust structures of the Balkan and southward, in both the offshore and onshore.

    During its transition to a market economy, Bulgaria benefited from foreign aid provided by Greece. One of the projects was the clinical and educational telemedicine link between the Medical University of Varna in Bulgaria and the Faculty of Medicine of Aristotle University of Thessaloniki in Greece. This began in 1997. In terms of the educational activities, the Bulgarian side of the network supports: an electronic classroom equipped with personal workstations, multimedia projectors and videoconference facilities; electronic design and publishing activities; Web hosting and mail server activities; and satellite communications. Communications are via ISDN. The main clinical experience has been remote consultations in immunology. This experience (admittedly limited) demonstrates that telemedicine can be used to provide assistance to remote colleagues. In addition, the use of telemedicine can greatly improve the quality of care available to travellers and migrant workers in cases where the patient cannot communicate with the attending physician because of a language barrier.

    1979-01-01

    Several tens of ritual plates are preserved in Bulgaria on which elements of glorification are found of god Mithras who gained popularity particularly in the 1st-IIIrd century in the regions of Thrace and today's North Bulgaria, then provinces of the Eastern Roman Empire. Mithras seemed to be respected by slaves, soldiers, and merchants alike, but was also an exemplar to the Roman emperors, being considered by them as Sol invictus or Deo invicto. The central scene in all plates is that of Mithras tauroctonus (Mithras, the killer of bulls). This scene is likewise of interest to veterinarians as it shows that in such early epoch the people that lived within the territory of Bulgaria of today used a method for the felling of large animals, the elements of which--fixing the head and bending it backwards, fastening the thorax with a belt or another loop, loading the animal's back--are still existing and are used in a number of modern methods of felling (that of Hess, the Caucasian way of felling, the Chinese one of Dou-Chan-Than, etc.) Besides, the people of ancient time knew that ruminants have an incomplete upper dentition. They skilfully employed this to bring animals that had to be felled into an unusual nonphysiologic posture. Not sooner than 16 centuries prior to the preformists (the spermists) they supported the concept that the testes were the source of life.

    Abstract The present catalogue of the ants (Hymenoptera, Formicidae) of Bulgaria is made on a base of critical reconsideration of literature (covering the period from 1892 till 2009 and part of 2010) as well as on examination of the authors‘ and several museum‘s collections. A lot of data were omitted in the previous Bulgarian monograph on ants, lots of new data were recently added and many important additions and alterations were made due to taxonomic revisions of Eurasian Formicidae during the last three decades. Two new species are reported for the country [Temnothorax graecus (Forel, 1911) and Temnothorax cf. korbi (Emery, 1924)]. This catalogue contains a list of 163 ant species belonging to 40 genera of 6 subfamilies now known from Bulgaria. Synonyms and information on the previously reported names in relevant publications are given. Known localities of the species are grouped by geographic regions. Maps with concrete localities or regions for each species were prepared. The conservation status of 13 ant species is given as they are included in IUCN Red List of Threatened Species and Bulgarian Biodiversity Act. In comparison with adjacent Balkan regions the ant fauna of Bulgaria is quite rich and its core is composed of South European elements. PMID:21594018

    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. The system consists of three components: MM5 - the 5th generation PSU/NCAR Meso-meteorological Model used as meteorological pre-processor; CMAQ - the Community Multiscale Air Quality System CMAQ; SMOKE - the Sparse Matrix Operator Kernel Emissions Modelling System - the emission model [4]. 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 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 air pollution pattern is formed as a result of interaction of different processes, so knowing the contribution of each for different meteorological conditions and given emission spatial configuration and temporal behaviour could be interesting. Therefore 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.

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

    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.

    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.

    OBJECTIVE: To characterize the circumstances in which poliomyelitis occurred among three children in Bulgaria during 2001 and to describe the public health response. METHODS: Bulgarian authorities investigated the three cases of polio and their contacts, conducted faecal and serological screening of children from high-risk groups, implemented enhanced surveillance for acute flaccid paralysis, and conducted supplemental immunization activities. FINDINGS: The three cases of polio studied had not been vaccinated and lived in socioeconomically deprived areas of two cities. Four Roma children from the Bourgas district had antibody titres to serotype 1 poliovirus only, and wild type 1 virus was isolated from the faeces of two asymptomatic Roma children in the Bourgas and Sofia districts. Poliovirus isolates were related genetically and represented a single evolutionary lineage; genomic sequences were less than 90% identical to poliovirus strains isolated previously in Europe, but 98.3% similar to a strain isolated in India in 2000. No cases or wild virus isolates were found after supplemental immunization activities were launched in May 2001. CONCLUSIONS: In Bulgaria, an imported poliovirus was able to circulate for two to five months among minority populations. Surveillance data strongly suggest that wild poliovirus circulation ceased shortly after supplemental immunization activities with oral poliovirus vaccine were conducted. PMID:12973639

    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.

    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.

    During its transition to a free economy, Bulgaria benefited from foreign aid provided by Greece. One of the projects was the clinical and educational telemedicine link between the Medical University of Varna in Bulgaria and the Faculty of Medicine of Aristotle University of Thessaloniki in Greece. This began in 1997. In terms of the educational activities, the Bulgarian side of the network supports (a) electronic design and publishing activities, (b) web hosting and mail server activities and (c) satellite communications. In addition it supports an electronic classroom equipped with personal workstations, multimedia projectors and videoconference facilities. Communications are via the ISDN network. In terms of its telemedicine activities, the network provides remote medical assistance to "language handicapped" travellers and to migrant workers in both countries. The main clinical experience is remote consultations in immunology. This admittedly limited experience demonstrates that telemedicine can be used to provide assistance to remote colleagues. In cases where the patient cannot communicate with the attending physician, the use of telemedicine can greatly improve the quality of care available to travellers and migrant workers.

    The present article describes the importance of human echinococcosis as a public health problem in Bulgaria, outlines the control measures carried out and evaluates comparatively the situation over three periods spanning 46 years (1950-1995). During the first period (1950-62), a total of 6469 new surgically confirmed cases of hydatid disease were recorded in Bulgaria, with an annual incidence of 6.5 per 100,000 population, and the infestation rate in domestic animals and dogs was high. Echinococcosis was endemic throughout the country. The organization of a control campaign, initiated in 1960, led to a considerable improvement in the situation during the second period (1971-82). Morbidity among humans gradually decreased, with an average incidence of 2.0 per 100,000, and the proportion of infected animals also fell. The distribution of echinococcosis was characterized as sporadic or of low endemicity. During the third period (1983-95), owing to administrative irregularities and economic changes, funds for supporting the campaign were reduced and control structures were dismantled. As a result, the incidence rose to 3.3 per 100,000. Echinococcosis again became endemic, in some regions hyperendemic. The findings provide convincing evidence that cessation of control measures or reduction of campaign activity can lead to intensification in the transmission of Echinococcus granulosus and to a resurgence in echinococcosis to previous levels.

    Temperature, air humidity and atmospheric pressure measurements in Ruse region for 40 years period are statistically studied in this paper. Descriptive statistics, Pearson correlation coefficients and linear regression models for these characteristics are presented and commented. The most variable atmospheric parameter is air humidity during the spring seasons. The hardest change of temperature and atmospheric pressure is during January. Temperature has biggest change in January and smallest - in July. Humidity has biggest change in April and smallest - in October. Atmospheric pressure has biggest change in January and smallest - in July. Characteristics temperature and atmospheric pressure of spring (April) and autumn (October) are very similar. Summer temperatures and atmospheric pressure (July) have smallest change. The atmospheric temperature data for Ruse region are also compared with the official basic data for Bulgaria. It is shown that mean values of the temperature in Ruse region are bigger than the mean temperature for Bulgaria. It is shown that the winter and spring temperatures for Ruse region are slightly going up lately which could be connected with the typical for Ruse region air pollution especially by particle matter.

    Several Hantaviruses cause hemorrhagic fever with renal syndrome (HFRS) in Europe: Dobrava-Belgrade virus (DOBV), Puumala, Saaremaa, Sochi, and Seoul virus. Although HFRS is endemic in Bulgaria, genome sequences of hantaviruses have never been detected in wild rodents. To identify rodent reservoirs, a total of 691 rodents from three endemic regions were trapped in 2011-2012 and screened by TaqMan RT-PCR for detection of hantaviral genomic RNA. Partial small (S) and/or large (L)-segment sequences were recovered from six Apodemus mice: five of the species A. flavicollis and one A. agrarius. Phylogenetic analysis revealed that all recovered sequences belonged to DOBV. On the phylogenetic trees, the novel Bulgarian hantavirus sequences clustered together with sequences of established previously DOBV variants recovered from Bulgarian HFRS patients and also with variants found in wild rodents trapped in Slovenia, Greece, and Slovakia. One of the novel Bulgarian DOBV S-sequences from A. agrarius was related closely to DOBV sequences recovered from A. flavicollis, suggesting a spillover of DOBV from its natural host to A. agrarius mice. The results of this study confirmed the circulation of DOBV in wild rodents in Bulgaria. The complexity of the epidemiological situation in the Balkans requires further studies of hantaviruses in rodent hosts and human HFRS cases.

    In Europe and particularly in Bulgaria, Roma represent the largest low-status minority group that is subjected to marked public intolerance and discrimination. This study examined links among Roma (N = 207) and Bulgarian (N = 399) adolescents' ethnic, familial, and religious identities as salient identity aspects for their psychological wellbeing. Results indicated that, as expected, Roma youth reported lower levels of wellbeing than Bulgarian youth. The latter revealed a weaker religious identity than Roma youth, whereas no ethnic group differences emerged regarding Bulgarian or familial identity. Furthermore, we observed that collective identity was higher in older participants of both groups. Finally, a multigroup analysis using structural equation modeling showed that collective identity was a positive predictor of wellbeing for both Roma and Bulgarian adolescents. Findings demonstrated differences in salience as well as structural communalities regarding ways in which collective identity affects wellbeing of youth from two ethnically diverse communities.

    An operational prototype of the Integrated Bulgarian Chemical Weather Forecasting and Information System is presented. This version of the system is limited to relatively low resolution (10 km) but covers all Bulgaria. It is based on the US EPA Models-3 System (MM5, SMOKE and CMAQ). The meteorological input to the system is the Bulgarian operational numerical weather forecast. The boundary conditions are taken from analogous Greek system (Aristotle University of Thessaloniki). Bulgarian system runs automatically twice a day (00 and 12 UTC) and produces 48-hour forecast. The part of the results of each System's run is post-processed in a way to be visualized and uploaded to a respective web site. In the paper, description of the System is given together with a demonstration of its products. In addition highlights of Systems upgrade will be given.

    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.

  1. Household energy management strategies in Bulgaria's transitioning energy sector

    Carper, Mark Daniel Lynn

    Recent transition literature of post-socialist states has addressed the shortcomings of a rapid blanket implementation of neo-liberal policies and practices placed upon a landscape barren of the needed institutions and experiences. Included in these observations are the policy-making oversight of spatial socioeconomic variations and their individual and diverse methods of coping with their individual challenges. Of such literature addressing the case of Bulgaria, a good portion deals with the spatial consequences of restructuring as well as with embedded disputes over access to and control of resources. With few exceptions, studies of Bulgaria's changing energy sector have largely been at the state level and have not been placed within the context of spatial disparities of socioeconomic response. By exploring the variations of household energy management strategies across space, my dissertation places this resource within such a theoretical context and offers analysis based on respective levels of economic and human development, inherited material infrastructures, the organization and activities of institutions, and fuel and technological availability. A closed survey was distributed to explore six investigational themes across four geographic realms. The investigational themes include materials of housing construction, methods of household heating, use of electrical appliances, energy conservation strategies, awareness and use of energy conservation technologies, and attitudes toward the transitioning energy sector. The geographic realms include countrywide results, the urban-rural divide, regional variations, and urban divisions of the capital city, Sofia. Results conclude that, indeed, energy management strategies at the household level have been shaped by multiple variables, many of which differ across space. These variables include price sensitivity, degree of dependence on remnant technologies, fuel and substitute availability, and level of human and

    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 CO{sub 2} 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; waste-heat 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. 3 refs.

    The IRT 2000 research reactor, operated by the Bulgarian Institute for Nuclear Research and Nuclear Energy (INRNE), safely shipped all of their Russian-origin nuclear fuel from the Republic of Bulgaria to the Russian Federation beginning in 2003 and completing in 2008. These fresh and spent fuel shipments removed all highly enriched uranium (HEU) from Bulgaria. The fresh fuel was shipped by air in December 2003 using trucks and a commercial cargo aircraft. One combined spent fuel shipment of HEU and low enriched uranium (LEU) was completed in July 2008 using high capacity VPVR/M casks transported by truck, barge, and rail. The HEU shipments were assisted by the Russian Research Reactor Fuel Return Program (RRRFR) and the LEU spent fuel shipment was funded by Bulgaria. This report describes the work, approvals, organizations, equipment, and agreements required to complete these shipments and concludes with several major lessons learned.

    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.

    Lungs of 52 ruminants from different regions of Bulgaria, 16 from goats (Capra aegagrus f. domestica L.), 15 from sheep (Ovis ammon f. domestica L.), 11 from mouflons (Ovis musimon L.), and 10 from chamois (Rupicapra rupicapra L.), were investigated. The aim of the study was to determine the species composition of small lungworms in these hosts. The obtained results are summarized with those of previous studies, and a picture of the present status of the species composition of protostrongylids in ruminants from Bulgaria is forwarded. Morphometric data about the species Muellerius capillaris, Cystocaulus ocreatus, Neostrongylus linearis, Protostrongylus brevispiculum, and Protostrongylus rufescens are presented. The data on the morphology of these five species are supplied for the first time both for Bulgaria and the south-east part of the European continent.

    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.

  10. SVAT modelling in support to flood risk assessment in Bulgaria

    2013-04-01

    This study explores the benefit that can be drawn from incorporating the diagnosis of initial soil moisture of the top vegetation/soil layer and its anomalies as parameters in support of operational weather forecasting. For that purpose, a 1D vertical numerical land surface scheme, referred to as Soil Vegetation Transfer Model (‘SVAT_bg’) has been developed to simulate the soil-vegetation-atmosphere mass and energy transfer, accounting for local soil/climate features. The model is run daily for estimating soil moisture content and on this basis, a biogeophysical index designating Soil Moisture Availability Index (SMAI) to vegetation land cover is derived. SMAI is introduced as a measure of the proportion between the energy and water balances and their anomalies at different weather/climate conditions through a 6-level threshold scheme of land surface moistening. To facilitate the use of SMAI as a diagnostic tool for operational forecasting purposes, it is generated on a daily basis and visualised by colour-coded maps, covering the main administrative regions of Bulgaria in combination with a numerical part, which indicates the required flood-producing rainfall quantities (specific for each region). In case of overmoistening conditions, the numerical part denotes the rainfall excess above the soil saturation moisture content. The utility of this approach is illustrated in two case studies of severe weather produced by deep convection and a rapid cyclogenesis developed at initial ‘dry’/‘wet’ soil moisture anomalies, respectively. The thermodynamic conditions and space-time structure of the rainfall are analysed by NWP output fields and satellite information. The study contributes to a better definition of the role of vegetation-soil moistening in flood risk forecasting within strong synoptic scale forcing regimes. The utility of the results comes also from the recognition of soil moisture as a meteorological forcing factor, which may affect both severity

    Abstract 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.

    There are still too many unsafe abortions performed worldwide. Together with the efforts to reduce the abortion by choice, we note a rise in the need for mid trimester pregnancy termination for medical reasons. The article looks at the past present and future perspective of the abortion as a procedure in Bulgaria. States the fact that medical abortion is officially not widely performed. We reckon that with the existing guidelines by WHO and with Mifepriston and Misoprostol recently registered in Bulgaria, it is time for the medical abortion to become part of the clinical practice in Bulgaria. We believe that early medical abortion as well as mid trimester induced abortion is and adequate if not better alternative to the existing in Bulgaria procedures.

  10. Probabilistic Seismic Hazard Assesment for Bulgaria as a Basis for a new National Building Code

    The territory of Bulgaria represents a typical example of high seismic risk area in the eastern part of the Balkan Peninsula. Bulgaria contains important industrial areas that face considerable earthquake risk. Moreover, the seismicity of the neighboring countries, like Greece, Turkey, former Yugoslavia and Romania (especially Vrancea-Romania intermediate earthquakes involving the non-crustal lithosphere), influences the seismic hazard in Bulgaria. Seismic hazard maps proposed as part of a new building code for Bulgaria based on the recommendations in EUROCODE 8 are presented in the study. The probabilistic seismic hazard analysis (PSHA) carries out integration over the total expected seismicity during a given exposure period to provide the estimate of a strong-motion parameter of interest with a specified confidence level. The basic approach used for the creation of ground motion maps combines via GIS, source-geometry, earthquake occurrence model, the strength of the earthquake sources, and the appropriate attenuation relations. In the study seismic hazard maps for Bulgaria are presented in terms of Peak Ground Acceleration (PGA) in agreement with EC8. As recommended in EC8, the maps are calculated for a 475 years return period (probability of exceedance of 10% in 50 years) for the design earthquake and for a 95 years return period (probability of exceedance of 10% in 10 years) for weaker earthquakes with higher frequency of occurrence. The PSHA was performed, using the Bulgarian version of computer code EQRISK. For the sensitivity analysis on the characterization of the seismicity in the seismic sources a PSHA for 500 randomly chosen models was run. The results suggested that uncertainties in seismic characteristics have relatively small effect on the final seismic hazard. A procedure called disaggregation has been applied to examine the spatial and magnitude dependence of PSHA results. The aim is to determine the magnitudes and distances that contribute to the

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

    PubMed

    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

    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.

    Increased interest in water quality in coastal and marine areas stemming from the Water Framework Directive and the Marine Strategy Framework Directive has led to important questions in relation to policies that address nutrient loadings. This paper presents the results from a choice experiment study to assess the recreational damage associated with algal blooms caused by nutrients flows into Varna Bay, Bulgaria. Varna Bay is an important beach destination on the Black Sea coast of Bulgaria. Algal bloom events have been experienced frequently in the area. A choice experiment questionnaire was developed and applied in the Varna Bay area to assess the extent to which the quantity of algal blooms and the duration of the bloom affect recreational activities. The amount of bloom was found to be important, as respondents were on average willing to pay a one off tax of 18.97 Leva (9.73 euro) for a program that provides beaches free from algal blooms.

    East Balkan Swine (EBS) Sus scrofa is the only aboriginal domesticated pig breed in Bulgaria and is distributed on the western coast of the Black Sea in Bulgaria. To reveal the breed's genetic characteristics, we analysed mitochondrial DNA (mtDNA) and Y chromosomal DNA sequences of EBS in Bulgaria. Nucleotide diversity (πn ) of the mtDNA control region, including two newly found haplotypes, in 54 EBS was higher (0.014 ± 0.007) compared with that of European (0.005 ± 0.003) and Asian (0.006 ± 0.003) domestic pigs and wild boar. The median-joining network based on the mtDNA control region showed that the EBS and wild boar in Bulgaria comprised mainly two major mtDNA clades, European clade E1 (61.3%) and Asian clade A (38.7%). The coexistence of two mtDNA clades in EBS in Bulgaria may be the relict of historical pig translocation. Among the Bulgarian EBS colonies, the geographical differences in distribution of two mtDNA clades (E1 and A) could be attributed to the source pig populations and/or historical crossbreeding with imported pigs. In addition, analysis of the Y chromosomal DNA sequences for the EBS revealed that all of the EBS had haplotype HY1, which is dominant in European domestic pigs.

Based on data from a household survey, this paper examines the importance that health care consumers attach to quality, access and price. The survey was conducted in 2000 among the population of the region of Varna (the third largest city in Bulgaria). The elicitation of attribute importance was based on a self-explicated method. To analyse the data, an ordered logit regression was performed. The analysis shows that clinical quality is the most valued characteristic by Bulgarian health care consumers compared with social quality, access and price. Given the poor quality of health care provision in Bulgaria, the allocation of revenues to its improvement appears to be essential in order to raise patient satisfaction and to enhance social efficiency.

    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

    We have used IR spectroscopy, 1H NMR spectroscopy, high-performance liquid chromatography and thin-layer chromatography to study the composition of resin residues found in 22 amphorae from Apollonia Pontika (SE Bulgaria). In particular this analysis of the resin residues was aimed at discovering the content of the amphorae and to verify the hypothesis on the transport of wine, named "Retsina". Additionally this hypothesis has been confirmed by a similar analysis of the modern resin sample from Aleppo pine (Pinus Halepensis) growing in the Attica region (Greece).

    In this paper we describe a rare but relatively well-preserved Sardinian type underground well temple located at the village of Garlo, in Bulgaria. This dates to the fourteenth or thirteenth century BCE, and contains some unique architectural features. We postulate that the Garlo temple was used during the winter solstice for rituals associated with the 'newly-born Sun', underground water and the start of the new annual cycle of life. Solar and water cults are known from ancient Thrace, but previously they have never been combined in this way.

    The study was aimed at investigating the conditions and circumstances for the recruitment of prostitutes, as well as their reproductive history, working conditions, knowledge of and attitudes to sexually transmitted diseases (STDs), and use of prophylactic antibiotic therapy of these diseases. Two hundred prostitutes were investigated by in-depth interviews at STD clinics, private practices and hotels. Of the 200 prostitutes, 8 (4%) were less than 15 years old and 32 (16%) more than 25 years old. Most of the women came from rural villages. Half of them were gypsies. Most had a boyfriend (often the pimp). One-quarter had been or were on their way abroad to prostitute. Half were migrating within Bulgaria to prostitute. They claimed a high rate of condom use with customers, but seldom with their pimps or boyfriends. About one-tenth used antibiotics prophylactically. They had knowledge of classical STDs and HIV/AIDS but only in exceptional cases had they heard about chlamydial and human papillomavirus infections. They often cohabited with a female friend also often practising prostitution. It was concluded that recruitment is often easy as the prostitute can earn more from only one contact with a customer than their parents earn from work in a month. Symptoms suggestive of STD were very common in the prostitutes, i.e. in 43%. Bulgaria is a recruitment area for international prostitutes.

    A total of 36 consecutive clinical and two fecal-screening carbapenem-resistant Klebsiella pneumoniae isolates from two Bulgarian university hospitals (Varna and Pleven) were investigated. Susceptibility testing, conjugation experiments, and plasmid replicon typing were carried out. Beta-lactamases were characterized by isoelectric focusing, PCR, and sequencing. Clonal relatedness was investigated by RAPD and multilocus sequence typing (MLST). Most of the isolates demonstrated multidrug resistance profile. Amikacin and tigecycline retained good activity with susceptibility rates of 95 and 87%, respectively. The resistance rate to colistin was 63%. Six RAPD- and MLST-types were identified: the dominating MLST-type was ST15 (27 isolates), followed by ST76 (six isolates), and ST1350 (two isolates). ST101, ST258, and ST151 were detected once. All except one of the K. pneumoniae produced KPC-2, mostly in combination with CTX-M-15, while for one isolate (ST101) the enzymes OXA-48 and CTX-M-14 were found. All KPC-2-producing transconjugants revealed the presence of IncFII plasmid. The OXA-48- and CTX-M-14-producing isolate showed the presence of L/M replicon type. The dissemination of KPC-2-producing K.pneumoniae in Bulgaria is mainly due to the sustained spread of successful ST15 clone and to a lesser extent of ST76 clone. This is the first report of OXA-48 producing ST101 K. pneumoniae in Bulgaria.

    Building a boron neutron capture therapy (BNCT) facility is foreseen within the reconstruction of the Research Reactor IRT (IRT) of the Institute for Nuclear Research and Nuclear Energy of the Bulgaria Academy of Sciences (INRNE). The development of BNCT at IRT plays a very significant role in the plan for sustainable application of the reactor. A centralized scientific information system on BNCT is being built at the INRNE with the purpose to collect and sort new information as knowledge accumulated during more than thirty years history of BNCT. This BNCT information system will help the creation and consolidation of a well informed and interconnected interdisciplinary team of physicists, chemists, biologists, and radio-oncologists for establishing BNCT cancer treatment in Bulgaria. It will strengthen more intensive development of the national network as well as its enlargement to the Balkan region countries. Furthermore, to acquaint the public at large with the opportunity for BNCT cancer treatment will be addressed. Human, social, and economics results due to BNCT for many patients from Balkan region are expected.

    The shift from social democratic to a neoliberal consensus in modern welfare capitalist states is characterised by an emphasis on individual responsibility, consumer choice, market rationality and growing social inequalities. There has been little exploration of how neoliberalism has shaped the environment within which chronic illness is experienced and managed. This article explores the different articulations of neoliberalism manifest in the arena of personal illness management in Bulgaria and the UK. People with type 2 diabetes discussed their experiences in terms of struggling with diet, diabetes as a personal failure, integrating illness management and valued activities, and the trustworthiness of the healthcare system. The UK narratives were framed within an individual responsibility discourse while in Bulgaria lack of resources dominated discussions, which were framed as structurally generated and unrelated to individual capabilities and choices. Respondents faced personal management challenges related to consumer and healthcare market failures in both countries. Differences in market regulation and emerging stakeholder and interest coalitions influenced users' expectations and their navigation and adaption to market failures in managing their everyday illnesses. The UK and Bulgarian articulations of neoliberalism can be described differently: the first as a logic of managed choice and the second as a logic of unmanaged consumerism.

    The results from the first survey on food safety knowledge, attitudes and hygiene practices (KAP) among veterinary medicine students in Bulgaria are reported in this study. It was designed and conducted from September to December 2015 using structured questionnaires on food safety knowledge, attitudes and practices. Data were collected from 100 undergraduate veterinary medicine students from the Trakia University, Bulgaria. It was observed that the age and the gender did not affect food safety knowledge, attitudes and practices. There was no significant difference (p>0.05) on food safety knowledge and practices among students based on the years of study. A high level of food safety knowledge was observed among the participants (85.06%), however, the practice of food safety was above average (65.28%) while attitude toward food safety was high (70%). Although there was a significant awareness of food safety knowledge among respondents, there is a need for improvement on food safety practices, interventions on food safety and foodborne diseases.

    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.

    Man's impact on the environment has become global and presents an international problem. The selective ionic absorption by hydrophytes in littoral ecosystems may be used for indicating the chemistry of water medium and submersed soils. The purpose of this investigation was to determine the concentrations of heavy metals in the main species of aquatic macrophytes distributed in the Aldomirovsko swamp in the Sofia District, Bulgaria. An evaluation of the anthropogenic contamination of this area will be made before the area is declared a protected locality. Aldomirovsko is one of the few inland swamps which is well preserved in Bulgaria. The swamp is situated to the northwest of Slivnica town, at the foot of the Tri Usi hills, around 650 m above sea level. It is of Karst origin. The area is about 2.5 km[sup 2]. The water capacity of the swamp varies throughout the year. Its depth decreases down to 1.10 m and is maintained by rainfall. The pH varies from 7.5 to 8.0. There is a considerable layer of silt at the bottom, with a pH of about 8.5. Thus far the swamp has been mainly a study area for floristic, faunistic, phytocoenological and ecological investigations. 17 refs., 1 fig., 3 tabs.

    In this study, we report the first discovery of microdiamond inclusions in kyanite-garnet schists from the Central Rhodope Mountains in Bulgaria. These inclusions occur in garnets from metapelites that are part of a meta-igneous and meta-sedimentary mélange hosted by Variscan (Hercynian) orthogneiss. Ultra-high-pressure (UHP) conditions are further supported by the presence of exsolved needles of quartz and rutile in the garnet and by geothermobarometry estimates that suggest peak metamorphic temperatures of 750-800 °C and pressures in excess of 4 GPa. The discovery of UHP conditions in the Central Rhodopes of Bulgaria compliments the well-documented evidence for such conditions in the southernmost (Greek) part of the Rhodope Massif. Dating of garnets from these UHP metapelites (Chepelare Shear Zone) using Sm-Nd geochronology indicates a Late Cretaceous age (70.5-92.7 Ma) for the UHP metamorphic event. This is significantly younger than previously reported ages and suggests that the UHP conditions are associated with the Late Mesozoic subduction of the Vardar Ocean northward beneath the Moesian platform (Europe). The present-day structure of the RM is the result of a series of subduction-exhumation events that span the Cenozoic, alongside subsequent post-orogenic extension and metamorphic core complex formation.

    We report the first confirmed cases of NDM-1-producing Klebsiella pneumoniae infections in two hospitals in Bulgaria. The isolates were diverse in terms of plasmid and co-resistance gene content. K. pneumoniae PR2682, causing sepsis in patient with polytrauma due to traffic accident, harbored blaNDM-1,blaCMY-4, blaCTX-M-15, blaSHV-1, blaTEM-1b, qnrB, and aac(6')-Ib. blaNDM-1 was transferable by conjugation and located on an IncA/C plasmid of 176-kb, which also carried blaCMY-4, blaCTX-M-15, blaTEM-1b, and qnrB. K. pneumoniae PR2830, causing urinary tract infection in prostate cancer patient, harbored blaNDM-1,blaSHV-1, blaTEM-1, and aac(6')-Ib. blaNDM-1 was carried on an 86-kb IncA/C plasmid transferable by conjugation together with blaTEM-1, and aac(6')-Ib. Multilocus sequence typing indicated that the two isolates belonged to sequence type ST11. The emergence of NDM-1-producing K. pneumoniae indicates that blaNDM-1-mediated resistance is already disseminated among Enterobacteriaceae in Bulgaria. Our results further confirm the role of the Balkans as a secondary reservoir where NDM-encoding genes originate.

    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.

    The purpose of this study was to explore access of Roma in South-Eastern Europe to sexual and reproductive health services. We conducted 7 focus group discussions with a total of 58 participants from Roma communities in Albania, Bulgaria and Macedonia. Our study revealed a number of barriers for Roma when accessing sexual and reproductive health services. Among the most important were the overall lack of financial resources, requests by health care providers for informal payments, lack of health insurance and geographical barriers. Health systems in the region seem to have failed to provide financial protection and equitable services to one of the most vulnerable groups of society. There is also a need for overcoming racial discrimination, improving awareness and information and addressing gender inequalities.

    GC-MS analysis of alkaloid profiles of five Fumaria species, naturally grown in Bulgaria (F. officinalis, F. thuretii, F. kralikii, F. rostellata and F. schrammii) and analysis of acetylcholinesterase inhibitory activity of alkaloid extracts were performed. Fourteen isoquinoline alkaloids were identified, with the principle ones being protopine, cryptopine, sinactine, parfumine, fumariline, fumarophycine, and fumaritine. Protopine contents, defined by HPLC analysis varied between 210.6 ± 8.8 μg/g DW (F. schrammii) and 334.5 ± 7.1 μg/g DW. (F. rostellata). While all of the investigated alkaloid extracts significantly inhibited acetylcholinesterase activity, the F. kralikii demonstrated the highest level of inhibition (IC(50) 0.13 ± 0.01 mg extract/mL).

    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.

    This report describes the first identification of OXA-24 carbapenemase-producing Acinetobacter baumannii isolates from Bulgaria. According to national surveillance data A. baumannii along with Pseudomonas aeruginosa are the most troublesome microorganisms in hospital environment with high rates of acquired carbapenem resistance. In the present study real-time multiplex PCR was performed to identify the most common carbapenemase genes in 15 non-duplicate carbapenem-resistant A. baumannii isolates collected in 2012. The results showed lack of KPC, GES, VIM, IMP-type enzymes. Four A. baumannii isolates tested positive by PCR for the acquired OXA-24 together with the intrinsic OXA-51 carbapenemase. OXA-24 and OXA-23 were determined as co-existent in one isolate. Two isolates were identified with OXA-23 in addition to the OXA-51 carbapenemase.

    A hominid upper premolar was discovered in the Azmaka quarry, near Chirpan (Bulgaria). The associated fauna, especially the co-occurrence of Choerolophodon and Anancus among the proboscideans, and Cremohipparion matthewi and Hippotherium brachypus among the hipparions, constrains the age of the locality to the second half of the middle Turolian (ca. 7 Ma), making it the latest pre-human hominid of continental Europe and Asia Minor. The available morphological and metric data are more similar to those of Ouranopithecus from the Vallesian of Greece than to those of the early to middle Turolian hominids of Turkey and Georgia, but the time gap speaks against a direct phyletic link, and Turolian migration from the east cannot be rejected.

    Vine is a traditional branch of plant growing in Bulgaria. The exact location of the vine culture is a specific complex of environmental factors influencing its development, such as climate, soil, landscape and traditions of the region. GIS is a platform to better manage, evaluate and present spatial data in a useful visual form. It's improves the decision-making by combining data with accurate location and management the vineyards. In the present survey were studied and analyzed the factors in choosing an appropriate location for the cultivation of vine varieties in selected regions of Plovdiv. Climatic and soil characteristics, topography and environmental factors as well as presence of virus vector nematodes from family Longidoridae in creating the vines through GIS spatial analysis are taken into account.

  1. Regulatory barriers to equity in a health system in transition: a qualitative study in Bulgaria

    PubMed Central

    2011-01-01

    Background Health reforms in Bulgaria have introduced major changes to the financing, delivery and regulation of health care. As in many other countries of Central and Eastern Europe, these included introducing general practice, establishing a health insurance system, reorganizing hospital services, and setting up new payment mechanisms for providers, including patient co-payments. Our study explored perceptions of regulatory barriers to equity in Bulgarian 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 The participants in our study reported a variety of regulatory barriers which undermined the principles of equity and, as far as the health insurance system is concerned, solidarity. These included non-participation in the compulsory health insurance system, informal payments, and charging user fees to exempted patients. The participants also reported seemingly unnecessary treatments in the growing private sector. These regulatory failures were associated with the fast pace of reforms, lack of consultation, inadequate public financing of the health system, a perceived "commercialization" of medicine, and weak enforcement of legislation. A recurrent theme from the interviews was the need for better information about patient rights and services covered by the health insurance system. Conclusions Regulatory barriers to equity and compliance in daily practice deserve more attention from policy-makers when embarking on health reforms. New financing sources and an increasing role of the private sector need to be accompanied by an appropriate and enforceable regulatory framework to control the behavior of health care providers and ensure equity in access to health services.

    Major economic transitions typically entail changes in the availability of and purchasing power for different types of foods leading to long-term changes in the composition of the diet. Bulgaria, a former Eastern Bloc country, underwent a difficult and protracted transition from a centralized to market economy with acute economic crises and a much slower recovery of income levels than in Poland, the Czech Republic, and Hungary. Using annual data from the Bulgarian National Household Survey, we study changes in the reported consumption of major foods (excluding alcoholic drinks) and their constituent macronutrients from 1985 to 2002, examining also the differences in dietary patterns between the period prior to and following the transition. The consumption of most major food items decreased, resulting in a fall in per capita energy consumption of 429 kcal/day (1.80 MJ/d), following the economic transition of 1991. As expected, the consumption of foods that were more expensive per unit of energy decreased greater than cheaper foods, -34% for animal products and -19% for visible fats, but only -10% for carbohydrates. These changes are related to the changes in income and market prices as well as the general negative trend in economic growth and hyperinflation in the mid-1990s. Thus, Bulgaria experienced a decrease in food consumption without significant changes in the dietary pattern following the economic transition of 1991. The fact that part of this decline may be attributed to continued economic challenges suggests that future transitions in the diet may be expected as economic development proceeds.

    Background: One of Europe’s most well-developed industrial regions is found in the Republic of Bulgaria. The industrialization of the region has a big impact on air pollution. Thermal power plant “Maritza East” (the largest of its kind in southeastern Europe), the army training range, machine manufacturers, household heating and high volume of automobile traffic are all major sources of pollution in the region. Methods: A five year study (2009–2013) followed yearly concentrations of principal atmospheric pollutants such as sulfur dioxide, dust, nitrogen dioxide, lead aerosols and hydrogen sulfide, and the way in which those levels had an effect on morbidity (outpatient and inpatient medical care) in the area. Statistical processing of data has been completed to represent and analyze the collected data in nonparametric and alternative format. Results: Atmospheric pollution affects human health directly through pathological changes in the human organism. The registered outpatient care provided for the period 2009–2013 is highest for diseases of the cardiovascular system (11.85%), the respiratory system (17.34%) and the genitourinary system (9.76%). The registered rate of hospitalization for the same period is for diseases of the digestive system (11.90%), the cardiovascular system (11.85%), respiratory system (10.86%) and the genitourinary system (8.88%). Conclusion: The observed period shows a decrease in average yearly concentrations of the principal atmospheric pollutants in the industrial region (Bulgaria) and reflects a decrease in morbidity based on outpatient care and an increase in morbidity by inpatient care (hospitalization). Our findings should be corroborated in future longitudinal studies. PMID:27252921

    Paediatric acute gastroenteritis is a global public health problem. Comprehensive laboratory investigation for viral, bacterial and parasitic agents is helpful for improving management of acute gastroenteritis in health care settings and for monitoring and controlling the spread of these infections. Our study aimed to investigate the role of various pathogens in infantile diarrhoea in Bulgaria outside the classical winter epidemics of rotavirus and norovirus. Stool samples from 115 hospitalized children aged 0-3 years collected during summer months were tested for presence of 14 infectious agents - group A rotavirus, astrovirus, Giardia, Cryptosporidium and Entamoeba using ELISAs; norovirus by real-time RT-PCR; picobirnavirus and sapovirus by RT-PCR; adenovirus using PCR, and Salmonella, Shigella, Escherichia coli, Yersinia and Campylobacter using standard bacterial cultures. Infectious origin was established in a total of 92 cases and 23 samples remained negative. A single pathogen was found in 67 stools, of which rotaviruses were the most prevalent (56.7 %), followed by noroviruses (19.4 %), enteric adenoviruses (7.5 %), astroviruses (6.0 %), bacteria and parasites (4.5 % each) and sapoviruses (1.4 %). Rotavirus predominant genotypes were G4P[8] (46.3 %) and G2P[4] (21.4 %); for astroviruses, type 1a was the most common, while the GII.4/2006b variant was the most prevalent among noroviruses. Bacteria were observed in five cases, with Salmonella sp. as the most prevalent, while parasites were found in ten stool samples, with Giardia intestinalis in five cases. The results demonstrated high morbidity associated with viral infections and that rotavirus and norovirus remain the most common pathogens associated with severe gastroenteritis during summer months in Bulgaria, a country with a temperate climate, and significant molecular diversity among circulating virus strains.

    We use survey data from Bulgaria and Hungary to investigate the determinants of whether women intend to have a first or a second child and, if so, whether they intend to have the child within the ensuing 2 years or later. These determinants differ significantly by the order and timing of the intended birth. The variables used include measures of anomie and social capital and these appear to be among the factors that determine both whether to have a child and when. There is some evidence that these measures and economic factors are relatively more important in Bulgaria than in Hungary, and that ideational factors are more important in Hungary, particularly in the case of voluntary childlessness.

    The objects of investigation are the major crops in Bulgaria (winter wheat, winter barley, sunflower and maize). The purpose of this paper is to 1) identify major crops using satellite data with low spatial resolution of 1000 m using agro-phenological information; 2) monitoring based on NDVI time-series values for the years 2007, 2008 and 2010, where anomaly events occur based on the information in the National Institute of Meteorology and Hydrology at the Bulgarian Academy of Sciences (NIMH-BAS) agrometeorological monthly bulletins. The current paper shows the massive potential of using low spatial resolution satellite data in identfying crops and monitoring the development anomalies on crops. This research will contribute in applying and elaborating JRC MARS methodology in Bulgaria by using low resolution SPOT-VGT NDVIs S10 satellite product.

    Hemorrhagic fever with renal syndrome (HFRS) and Crimean-Congo hemorrhagic fever (CCHF) are the 2 widespread viral hemorrhagic fevers occurring in Europe. HFRS is distributed throughout Europe, and CCHF has been reported mainly on the Balkan Peninsula and Russia. Both hemorrhagic fevers are endemic in Bulgaria. We investigated to what extent acute undifferentiated febrile illness in Bulgaria could be due to hantaviruses or to CCHF virus. Using enzyme-linked immunosorbent assays (ELISAs), we tested serum samples from 527 patients with acute febrile illness for antibodies against hantaviruses and CCHF virus. Immunoglobulin M (IgM) antibodies against hantaviruses were detected in 15 (2.8%) of the patients. Of the 15 hantavirus-positive patients, 8 (1.5%) were positive for Dobrava virus (DOBV), 5 (0.9%) were positive for Puumala virus (PUUV), and the remaining 2 were positive for both hantaviruses. A plaque reduction neutralization test (PRNT) confirmed 4 of the 10 DOBV-positive samples. PRNT was negative for all PUUV-positive samples. Serologic evidence of recent CCHF virus infection was found in 13 (2.5%) of the patients. Interestingly, HFRS and CCHF were not only detected in well-known endemic areas of Bulgaria but also in nonendemic regions. Our results suggested that in endemic countries, CCHF and/or HFRS might appear as a nonspecific febrile illness in a certain proportion of patients. Physicians must be aware of possible viral hemorrhagic fever cases, even if hemorrhages or renal impairment are not manifested.

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. The main goal of the paper is framing in conditions of the expected climate changes in our country for period 2020-2050-2070 and the most likely impacts on the agriculture with inspection padding to the consequences in them and making physical conditions for development of proof farming in production regions of the country.

    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 organized participation of the Bulgarian scientists in the space research started in 1969 when a Group of Space Physics at the Bulgarian Academy of Sciences (BAS) was established. The first Bulgarian space equipment for ionosphere parameters measurement was created and launched on board satellite Intercosmos - 8 on 1 December 1972. Bulgaria became the 18th space country. Later in 1975 the Central Laboratory for Space Research (CLSR) was founded and the Bulgarian researchers participated successfully in the East European Intercosmos Program, developing equipment and carrying out experiments on the satellites Intercosmos - 12, 14, 19 and the heavy geophysical rockets Vertical - 3, 4, 6, 7, 10. The first Bulgarian cosmonaut George Ivanov was launched in space on board Soyuz-33 in 1979. The scientific program and equipment for this flight were entirely designed by Bulgarian scientists. The two satellites Intercosmos-Bulgaria-1300-I and II were entirely (I) or partially (II) furnished with Bulgarian scientific equipment designed to study the ionosphere-magnetosphere interactions and for remote sensing of the Earth. In 1987 the CLRS became Space Research Institute (SRI). The accumulated experience and scientific knowledge helped the Bulgarian scientists to develop a new scientific program SHIPKA for the flight of the second Bulgarian cosmonaut Alexander Alexandrov in 1988. Fifteen research devices and complexes, that continued working onboard the MIR Orbital Station (OS) long after the Bulgarian flight, were developed and 49 scientific experiments in the field of the space physics, remote sensing, space biology and medicine and space materials were conducted. The Bulgarian scientists also participated successfully in international programs such as VENUS-HALLEY (1985), PHOBOS (1988), AKTIVEN (1989), APEX (1990) and INTERBOL (1995, 1996). The achievements of the Bulgarian scientists from SRI in the field of the Space Biology and Medicine during the last 15 years are

    The prevention of the natural disasters and the performing management of reactions to crisis are common problems for many countries. The Romania-Bulgaria border region is significantly affected by earthquakes occurred in both territories: on the one-hand, Vrancea seismic source, with intermediate-depth events and on the other hand, crustal seismicity recorded in the northern part of Bulgaria (Shabla, Dulovo, Gorna Orjahovitza). The general objective of DACEA (2010-2013) project is to develop an system of earthquake alert in order to prevent the natural disasters caused by earthquakes in the cross-border area, taking into account the nuclear power plants and other chemical plants located along the Danube on the territories of Romania and Bulgaria. An integrated warning system is designed and implemented in the cross-border area. A seismic detection network is put in operation in order to warn the bodies in charge with emergency situations management in case of seismic danger. The main purpose of this network is: • monitoring of the four seismogenic areas relevant for the cross-border area, in order to detect dangerous earthquakes • sending the seismic warning signals within several seconds to the local public authorities in the cross-border area On the territory of Bulgaria the seismic network belonging to SEA is consists of: • 8 seismic stations equipped with Basalt digitizer, accelerometer Epi-sensor and BB seismometer KS2000. • 8 seismic stations equipped with Basalt digitizer, accelerometer Epi-sensor, warning and visual monitoring equipment. The stations are spanned allover the North Bulgaria. The sites were thoroughly examined and the most important requirement was the low level of noise or vibrations. SEA centers were established both in Sofia (in National Institute of Geophysics, Geodesy and Geography - NIGGG) and Bucharest (in National Institute of Research and Development for Earth Physics). Both centers are equipped with servers for data analyses

    1998-09-01

    A data set comprising individual host/parasite lists from 100 Lacerta viridis (Reptilia: Lacertidae) belonging to four isolated populations in Bulgaria was studied. A total of seven helminth species was recovered (Leptophallus nigrovenosus, Plagiorchis molini, Oswaldocruzia filiformis, Spauligodon extenuatus, Skrjabinelazia hoffmanni, Physaloptera clausa and Mesocestoides sp.). Lacerta viridis is a new host record for the first five of these species. Communities of intestinal helminths of L. viridis consist of a few species which resulted in a low species richness, abundance and diversity of infracommunities, which exhibit substantial homogeneity among the four samples. A similar pattern of dominance of two nematode species leading to a relatively high community similarity at both infra- and component community levels was observed. While intestinal helminth communities in lizards from 'marginal' habitats were dominated by the host generalist, O. filiformis, those in hosts from 'typical' habitats were dominated by the lizard specialist S. extenuatus. The results indicate that the characteristics of the host's habitat are important in determining the composition rather than structure of intestinal helminth communities in L. viridis.

    This article presents a well preserved bone artifact found in a prehistoric settlement mound near Karnobat, Bulgaria, and dated to the end of the V millennium BC. It has the shape of a shovel or shallow spoon with a short handle decorated with holes and notches (Figs.3,4). The author assumes that this is not a utilitarian object but rather a cultic one. It can be interpreted as both phallic shaped and as a stylized female figure. The total number of the holes and the long notches (31) is close to the number of days in a synodical lunar month: the notches on the "handle" can be used to count down the days in the waning and waxing moon phases, while the holes and the pits on the oval part correspond to the days around the full moon phase. The author brings out parallels from the Palaeolithic period in Ukraine (Fig. 5) and Italy (Fig. 6) with lunar calendar symbology on stylized anthropomorphic figures.

    The aim of this study is to describe the environments where the cercopithecid Mesopithecus was found during latest Miocene in Europe. For this purpose, we investigate the paleoecology of the herbivorous ungulate mesofauna of three very rich late Miocene fossil localities from southwestern Bulgaria: Hadjidimovo, Kalimantsi and Strumyani. While Mesopithecus has been found in the two first localities, no primate remains have yet been identified in Strumyani. Comparison between localities with and without primates using the herbivore mesofauna allows the cross-corroboration of paleoenvironmental conditions where this primate did and did not live. A multi-parameter statistical approach involving 117 equid and 345 bovid fossil dental and postcranial (phalanges, metapodia, astragali) remains from these three localities provides species to generic-level diet and locomotor habit information in order to characterize the environment in which Mesopithecus evolved. The analysis of dental mesowear indicates that the bovids were mainly mixed feeders, while coeval equids were more engaged in grazing. Meanwhile, postcranial remains show that the ungulate species from Hadjidimovo and Kalimantsi evolved in dry environments with a continuum of habitats ranging from slightly wooded areas to relatively open landscapes, whereas the Mesopithecus-free Strumyani locality was in comparison reflecting a rather contrasted mosaic of environments with predominant open and some more closed and wet areas. Environments in which Mesopithecus is known during the late Miocene were not contrasted landscapes combining open grassy areas and dense forested patches, but instead rather restricted to slightly wooded and homogeneous landscapes including a developed grassy herbaceous layer.

    Landscape change assessment was conducted in selected areas of Slovakia and Bulgaria in 1990-2000 using CORINE land cover (CLC) data layer analysis. Assessment of causes that led to these changes was undertaken, with an emphasis on those that determined the extensification of agriculture. The LC data were obtained under the CLC90 and I&CLC2000 projects, jointly managed by the European Environment Agency in Copenhagen, Denmark and the Joint Research Centre of the European Commission in Ispra, Italy. The CLC1990-2000-changes data layer was generated by overlaying the CLC90 and CLC2000 data layers for change in areas of a minimum 5 ha. The analysed causes of changes (driving forces) were then classified. Land cover (LC) changes characterizing urbanization processes occurred only in the Trnava and Tatras areas. Intensification of agriculture was also higher in these two areas. LC changes characterizing the extensification of agriculture were dominant in Plovdiv and Trnava. Deforestation and forestation were identified in all areas (Trnava, Tatras, Plovdiv, and Burgas). The basic reasons of these changes were related to the transformation of national economies from being centrally planned to market controlled, following the fall of socialism and before the countries joined the European Union.

    Four aquatic ecosystems (two rivers and two dams) situated in the western part of Bulgaria were investigated over a three years' period. The River Egulya and Petrohan dam are situated in mountainous regions at about 1000 m altitude, and are not influenced by any anthropogenic sources. Petrohan dam is a site for long-term ecosystem research as a part of Bulgarian long-term ecological research network. The other two systems belong to populated industrial areas. The River Martinovska flows through a region with former long-term mining activity, while Ogosta dam is near a battery production factory. Both the geochemical and geographical ecosystems' conditions are different, and their social usage as well. Ogosta dam water is used for irrigation and Petrohan dam for electric supply. The ecosystem sensitivity to heavy metals was evaluated by a critical load approach. Two criteria were used for risk assessment: critical load exceedance and microbial toxicity test. All studied ecosystems were more sensitive to cadmium than to lead deposition. The potential risk of Cd damage is higher for Petrohan dam and the River Egulya, where critical load exceedance was calculated for two years. Pseudomonas putida growth inhibition test detected a lack of toxicity for all studied ecosystems at the time of investigation with the exception of the low water September sample of the River Martinovska. The fast bacterial test is very suitable for a regular measurement of water toxicity because of its simplicity, lack of sophisticated equipment and clear results.

    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.

    AIM The aim of this study was to compare two nationwide cross-sectional studies of diabetes prevalence in Bulgaria (2006 and 2012) and to assess its dynamics. MATERIAL AND METHODS The two studies included 2396 and 2033 subjects, respectively. The International Diabetes Federation (IDF) diagnostic criteria were applied, and the data were weighed for type of settlement and age. RESULTS Diabetes prevalence was found to be 7.9% in 2006 and 9.55% in 2012, P = 0.06, showing an increase of 20.9%. The absolute increase was 0.9% in the females and 2.3% in the males (P < 0.09). The increase was the largest in those aged 50–59: [9.4%, 2006 vs. 15.7%, 2012, P < 0.01]. Diabetes prevalence increased in the 20–60-year olds by 6.8% and decreased in the elderly by 6.1%. Obesity increased from 26.7 to 32.7%, P < 0.02. CONCLUSIONS A significant increase in diabetes prevalence was found that necessitates healthcare measures and resources for community-based awareness and prevention programs. PMID:26005363

    2004-07-01

    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.

    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 < 15 years old. Vaccination status was available for 52% (n = 12,630) of cases. Of 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.

    The aim of this study was to characterize genetically Bulgarian Erwinia amylovora strains using pulsed-field gel electrophoresis (PFGE) analysis. Fifty E. amylovora strains isolated from different hosts, locations, as well as in different years were analysed by PFGE after XbaI, SpeI, and XhoI digestion of the genomic DNA. The strains were distributed into four groups according to their XbaI-generated profile. About 82% of the strains displayed a PFGE profile identical to that of type Pt2. Three strains belonged to the Central Europe Pt1 type. Two new PFGE profiles, not reported so far, were established--one for a strain isolated from Malus domestica and another for all Fragaria spp. strains. The same grouping of the strains was obtained after analysis of the SpeI digestion patterns. On the basis of PFGE profiles, after XbaI and SpeI digestion, a genetic differentiation between the strains associated with subfamily Maloideae and subfamily Rosoideae was revealed. The presence of more than one PFGE profile in the population of E. amylovora in Bulgaria suggests a multiple source of inoculum.

    Presented are results of lidar measurements and characterization of wildfire caused smoke aerosols observed in the atmosphere above the city of Sofia, Bulgaria, related to two local wildfires raging in forest areas near the city. A lidar systems based on a frequency-doubled Nd:YAG laser operated at 532 nm and 1064 nm is used in the smoke aerosol observations. It belongs to the Sofia LIDAR Station (at Laser Radars Laboratory, Institute of Electronics, Bulgarian Academy of Sciences), being a part of the European Aerosol Lidar Network. Optical, dynamical, microphysical, and geometrical properties and parameters of the observed smoke aerosol particles and layers are displayed and analyzed, such as: range/height-resolved profiles of the aerosol backscatter coefficient; integral aerosol backscattering; sets of colormaps displaying time series of the height distribution of the aerosol density; topologic, geometric, and volumetric properties of the smoke aerosol layers; time-averaged height profiles of backscatter-related Ångström exponent (BAE). Obtained results of retrieving and profiling smoke aerosols are commented in their relations to available meteorological and air-mass-transport forecasting and modelling data.

    Honey samples collected during 2007-2010 from serpentine and non-serpentine localities in the Eastern Rhodopes Mt. (Bulgaria) were characterized on the basis of their pollen content by qualitative melissopalynological analysis and physicochemical composition. Water content, pH, electrical conductivity, macroelements-K, Ca, Mg, P, and microelements-As, Cd, Co, Cr, Cu, Fe, Mn, Na, Ni, Pb, and Zn were determined after the Harmonised Methods of the International Honey Commission and ICP-AES method. The results from serpentine honey samples were compared with data from bee pollen collected from the same serpentine area. Different elements have different concentrations in honey from the same botanical type even collected from the same geographical region, same locality, and same beehive but in different vegetation season. The elements Mg, Mn, Ni, and P contribute mostly for separation of the serpentine honey samples based on measured elemental concentrations and performed principal component analysis. The element concentrations were higher in bee pollen and above the permissible limits for the toxic metals Cd and Pb. No specific indicator plant species was found for identification of the geographical origin of serpentine honey in relation to the forage of bees.

    Oral poliovirus vaccine (OPV) can cause, in extremely rare cases vaccine-associated paralytic poliomyelitis in recipients, or contacts of vaccinees. Three cases of vaccine-associated paralytic poliomyelitis (two contacts and one recipient) occurred in the Bourgas region of Bulgaria in the spring of 2006. The first two cases, notified as acute flaccid paralysis, were 55 days old unvaccinated twin brothers, having been in contact with vaccinees. The third case concerned a 4-month-old infant who had received the first OPV dose 37 days prior to the onset of illness. Complete clinical, epidemiological, virological, serological and molecular investigations of the children with paralysis and their contacts were undertaken. In all the three cases type 3 polioviruses were isolated from fecal samples and characterized as Sabin-like poliovirus strains. Type 3 polioviruses isolated from the twin brothers demonstrated by sequence analysis U-to-C back mutation at nt 472 of the 5' UTR, known to correlate with neurovirulence, and mutation in the VP1 region. Type 3 poliovirus isolated from the third child demonstrated in the 3D sequenced region a recombination with Sabin type 1 poliovirus. In the latter region, three silent mutations and one, resulting in amino acid substitution, were also observed. The clinical, epidemiological and virological data and the neurological sequelae observed 60 days following the onset of paralysis, confirmed the diagnosis of vaccine-associated paralytic poliomyelitis in all the three patients.

    One of the applications of the Global Navigation Satellite Systems (GNSS) Meteorology is to study intense precipitation events. Development of these applications is one of the tasks of working group two of the COST Action ES1206 Advanced Global Navigation Satellite Systems tropospheric products for monitoring severe weather events and climate (GNSS4SWEC). This work is a contribution to the COST Action ES1206 and targets the use of Integrated Water Vapour (IWV), derived with the GNSS Meteorology method, during convective events with heavy precipitation in Bulgaria. Twenty-two case studies were selected for 2012. For the analysis two-dimensional maps of the IWV distribution from GNSS and Meteosat are used. A case study on the 27 June 2012 shows a strong south north gradient of the water vapour on the Balkan Peninsula before the intrusion of cold and dry air. By using these techniques the passage of a cold front is timed on the 25 May 2012. The IWV peak is between 06:00 UTC and 12:00 UTC before the passage of the cold front at 18:00 UTC. Future work will be the use of NWP model (WRF)simulations and evaluate the model performance for the selected case studies for 2012.

    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 Lden 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/m3 (OR = 1.32, 95% CI: 0.28, 6.24), benzo alpha pyrene 6.0-14.02 ng/m3 (OR = 1.76, 95% CI: 0.52, 5.98) and high road traffic (OR = 1.40, 95% CI: 0.48, 4.07). Lden 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

    The Bulgarian National Astronomical Observatory (NAO) located close to the Rozhen ridge in the Rhodope Mountains near Smolyan, is presented with its history, functional characteristics and capabilities. Its latitude of 41° 41.5'N gives opportunities to investigate over 80{%} of the celestial sphere. The altitude of 1750 m lies within the height level that is most populated by observatories (1500-2500m). However, the astroclimate (mean seeing ˜ 2" and 35-40% clear sky time) is worse than that of the best world sites and corresponds to the mean for the continental Southern Europe. The light pollution near NAO is still the lowest among the Balkan sites, but some problems arise because of the ever growing illumination from the Pamporovo resort and the nearby towns of Smolyan and Chepelare. Equipped with 2-m, 70- and 60-cm stellar and 15-cm solar coronograph telescopes, NAO allows observations to be made for a wide range of optical astrophysical investigations: from Solar System bodies to extragalactic sources. The productivity of the 2-m telescope is quite comparable with that of other telescopes of similar class. Important studies (photometric, spectral, morphologic) of stellar clusters, flare stars, variable stars, nearby and distant galaxies were performed with/at the NAO telescopes. The 2-m telescope is very suitable for spectroscopic investigation with moderate resolution and it can be a subject of its future specialization in the era of giant telescopes of decameter size. The future of NAO can be connected with educational and conference activities if Bulgaria joins ESO - the most desirable way to develop astronomy in our land/in our country.

    The results of a palaeomagnetic investigation of a 27 m thick loess/palaeosol sequence in Viatovo (NE Bulgaria) are presented in this paper. The sequence consists of topsoil S 0, seven loess horizons (L 1-L 7) and six interbedded palaeosols (S 1-S 6) overlying a red clay (terra rossa) complex. Magnetic viscosity experiments, IRM acquisition, AMS analysis and NRM stepwise alternating and thermal demagnetisation experiments of pilot samples were implemented for precise determination of the characteristic remanence and construction of a reliable magnetostratigraphical scheme. Analysis of IRM acquisition curves using the expectation - maximization algorithm of Heslop et al. [Heslop, D., Dekkers, M., Kruiver, P., van Oorschot, H., 2002. Analysis of isothermal remanent magnetization acquisition curves using the expectation - maximization algorithm. Geophys. J. Int., 148, 58-64] suggests that the best fitting is obtained by three coercivity components. Component 1 corresponds to SD maghemite/magnetite, while component 2 is probably related to the presence of oxidised detrital magnetites. The third component shows varying coercivities depending on the degree of pedogenic alteration of the samples and probably reflects the presence of detrital magnetite grains oxidised at different degree. The relevance of the Viatovo section as a key representative sequence for the loess cover in the Danube basin is confirmed by the presence of geomagnetic polarity changes in the lower part of the sequence. The youngest one recorded in the seventh loess unit L 7 can be identified as corresponding to the Matuyama/Brunhes palaeomagnetic polarity transition. Two normal magnetozones were found in the red clay complex, probably corresponding to the Jaramillo and Olduvai subchronozones of the Matuyama chron.

    The Normacog Brief Battery (NBB) provides a comprehensive overview of an individual’s cognitive functioning within a short amount of time. It was originally developed for the Spanish population in Spain. However, there is a considerable need for brief batteries in clinical neuropsychological assessment, especially in eastern European countries. Cultural background and other individual characteristics—such as age, level of education, and sex—are shown to influence both cognition and patients’ performance on neuropsychological tests. Therefore, it is important to develop understanding of how and why culture impacts on cognitive testing and determine which sociodemographic variables affect cognitive performance. The current study aims to translate, adapt, and standardize the NBB in Bulgaria, Croatia, and the Netherlands, and to analyze the effect of sex, age, and education level on cognitive performance between these three countries. This brief battery assesses eleven cognitive domains, including those most currently relevant in cognition such as premorbid intelligence, attention, executive function, processing speed, and memory. The translation and adaptation of the battery for different cultures will be done using the back-translation process. After exclusion criteria, the current study will include a total sample of 300 participants (≥18 years old). The samples of 100 participants per country will be balanced through the consideration of their age and level of education. Effects of the sociodemographic variables (age, level of education, and sex) on cognitive performance are expected. Furthermore, this relationship is expected to differ across countries. A multivariate hierarchical linear regression will be used and exploratory analysis will be carried out to investigate further effects. The results will be particularly valuable for future research and assessment in cognitive performance. The growing demand for accurate and fast neuropsychological

    The measurement of life expectancy in terms of either good or poor health is a novel approach to studying the health of the population in Bulgaria. The pilot study reported here-carried out among people aged > or = 60 years in a middle-sized Bulgarian town-was designed to obtain information on the years of functional restrictions expected among the elderly. In accordance with the answers to a series of questions (recommended by WHO), subjects were categorized as disabled, handicapped, or having different states of perceived health. The indicators "disability-free life expectancy", "handicap-free life expectancy" and "healthy life expectancy" (based on self-perceived health) were calculated according to Sullivan's method. The results show, for example, that 8.0 of the 16.0 years that men aged 60 years may expect to live, on average, will be free of disability. For men aged 80 years the figures are 1.3 of 5.5 years. For women at 60 years and 80 years the results are 7.3 and 0.5 disability-free years of 19.2 and 7.3 expected life years, respectively. Similar results were found for handicap-free life expectancies and healthy life expectancies. At all ages, the proportion of life in a condition free of disability, free of handicap, or in perceived good health is substantially lower for women than for men. Women may expect to live longer, but a greater proportion of their life will be spent in poor health. The approach presented here for measuring the health status of the elderly may be helpful as an aid to planning medical and social care and for the development of public health policies.

    Abstract Background The knowledge of the ground-beetle fauna of Strandzha is currently incomplete, and is largely based on data from the Bulgarian part of the region and on records resulting from casual collecting. This study represents a critical revision of the available literature, museum collections and a three years field study of the carabid beetles of the Bulgarian and Turkish parts of Strandzha Mountain and the adjacent Black Sea Coast territories. New information A total of 328 species and subspecies of Carabidae, belonging to 327 species from the region of Strandzha Mountain and adjacent seacoast area, have been listed. Of these, 77 taxa represent new records for the Bulgarian part of the region, and 110 taxa new records for Turkish part of the studied region. Two taxa, one subgenus (Haptotapinus Reitter, 1886) and one species (Pterostichus crassiusculus), are new to the fauna of Bulgaria. Based on a misidentification, the species Apotomus testaceus is excluded from the list of the Bulgarian fauna. Seven species (Carabus violaceus azurescens, Apotomus rufus, Platynus proximus, Molops alpestris kalofericus, M. dilatatus angulicollis, Pterostichus merklii, and Calathus metallicus) are treated as doubtful for the regional fauna, and one (Apotomus rufus) also for the Bulgarian fauna. Altogether, 43 taxa collected in the Turkish part of the region are new for European Turkey. New taxa for Turkey are the genera Myas and Oxypselaphus, the subgenus Feronidius, and nine species and subspecies (Carabus granulatus granulatus, Dyschirius tristis, Bembidion normannum apfelbecki, B. subcostatum vau, Acupalpus exiguus, Myas chalybaeus, Oxypselaphus obscurus, Pterostichus leonisi, Pt. melas). In addition, there are a further seven species that are here confirmed for Turkey. PMID:27099564

    SciTech Connect

    1998-11-01

    Interest in water resources and hydropower has been low in Bulgaria for over 20 years and only about 33% of the potential hydropower available to the Country are currently being utilized. This is due in part to past design practices that utilized large reservoirs to regulate runoff and create the necessary head. The Iskar River does not allow for the typical design. However, in recent years, technical advancement in machinery design and more efficient turbine-generators has led to the development of low-head hydro projects. Studies determined that the Iskar Cascade can support low-head hydro development and could provide as much as 93 MW of capacity. This project will initially consist of the construction of three hydroelectric facilities along a 120-km section of the Iskar river in western Bulgaria. Each facility will consist of a powerhouse (housing a turbine and generator), an embankment dam, a concrete spillway with regulating gates, a fish passage, and associated transformers and switchgear. This report gives a description of the project, its sources of funding for specific measures to reduce greenhouse gas emissions, forecasts of greenhouse gas emissions with and without these specific measures, and other environmental considerations.

    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.

    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 "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.

    2016-01-01

    Background: During times of fiscal austerity, means of reimbursement decision-making are of particular interest for public health theory and practice. Introduction of advanced health technologies, growing health expenditures and increased public scrutiny over drug reimbursement decisions have pushed governments to consider mechanisms that promote the use of effective health technologies, while constraining costs. Aims: The study’s aim was to explore the current rationale of the drug reimbursement decision-making framework in Bulgaria. Our pilot research focused on one particular component of this process – the criteria used – because of the critical role that criteria are known to have in setting budgets and priorities in the field of public health. The analysis pursued two objectives: to identify important criteria relevant to drug reimbursement decision-making and to unveil relationships between theory and practice. Study Design: Cross-sectional study. Methods: The study was realized through a closed-ended survey on reimbursement criteria among four major public health stakeholders – medical professionals, patients, health authorities, and industry. Empirical outcomes were then cross-compared with the theoretical framework, as defined by current Bulgarian public health legislation. Analysis outlined what is done and what needs to be done in the field of public health reimbursement decision-making. Results: Bulgarian public health stakeholders agreed on 15 criteria to form a tentative optimal framework for drug reimbursement decision-making. The most apparent gap between the empirically found preferences and the official legislation is the lack of consideration for the strength of evidence in reimbursement decisions. Conclusion: Bulgarian policy makers need to address specific gaps, such as formal consideration for strength of evidence, explicit role of efficiency criteria, and means to effectively empower patient and citizen involvement in public health

  4. Post-Cretaceous to recent stress fields in the SE Moesian Platform (Bulgaria)

    The reconstruction of the stress fields in the SE Moesian Platform in Bulgaria has been made by means of earthquake fault-plane solutions, tectonic fracture and fold patterns, and physical (electrical) anisotropy in rocks restricted stratigraphically from the Early Cretaceous up to the Late Pliocene. The philosophy of the study is that the recognition of the older stress fields for a given area can be successful if the characteristics of the youngest ones are known. The contemporary stress field is discussed using the fault plane solutions from earthquakes and the kinematics of the activated faults. The reconstruction of the Post-Pliocene paleo-stress field was made by studies of conjugate shear joints systems in Upper Pliocene limestones. Measurements of elements of tectonic fractures were also performed in situ on more than 60 outcrops of rocks aged from Aptian to Pliocene. A limited number of sites were studied for electrical anisotropy using the Azimuthal Vertical Electrical Sounding method. A more complete study of the tectonic meso- and micro-structures has been performed on the Sarmatian sediments in the SE Moesian Platform. This study includes a description of the discovered folds, brittle tectonic analysis and reconstruction of the Post-Sarmatian paleo-stress field. As a result, it was deduced that the compression after the Early Cretaceous period is NE-SW directed. The direction of compression since Sarmatian to Early Quaternary was NW-SE. A clockwise rotation of the main stress axes was established for a number of sites. The contemporary contraction is directed also NW-SE, according to the fault-plane solutions determined for crustal earthquakes in the region. This result is tested using the data from the GPS measurement recently performed in this part of the Balkan Peninsula. It could be suggested that there has been a clockwise rotation of the stress field due to the evolution of curved fold-thrust belt in the south-eastern Carpathians and the

    The purpose of this investigation was to review the clinical cases diagnosed as systemic or extraintestinal salmonellosis between 2005 and 2010 in Bulgaria, to determine the antimicrobial resistance of the causative salmonellae, and to analyze the pulsed field gel electrophoresis (PFGE) profiles of extraintestinal Salmonella Corvallis isolates. Culture, biochemical tests, and serotyping were performed. Resistance to 12 antimicrobial agents was studied with the Bauer-Kirby disk diffusion method. The double-disk synergy method was used for the screening of the presence of extended-spectrum beta-lactamases (ESBLs). PFGE typing and analysis of the dendrogram was performed for the comparative investigation of Salmonella Corvallis isolates. Between 2005 and 2010, 2,227 human non-typhoid Salmonella isolates were investigated at the National Reference Laboratory of Enteric Pathogens, Sofia, Bulgaria. Thirty-three strains (1.48 %) from nine national regions were isolated from patients with systemic and extraintestinal forms of salmonellosis. The serotype distribution was as follows: S. enteritidis (n = 21), S. choleraesuis (diphasic n = 3; monophasic n = 3), S. typhimurium (n = 2), Salmonella Corvallis (n = 2), Salmonella Montevideo (n = 1), and S. javiana (n = 1). Eight patients developed severe forms of infections: sepsis (n = 2), septic shock (n = 1 with fatal outcome), meningitis (n = 3), and acute renal failure (n = 2). Twenty-two percent of isolates were resistant to ampicillin and gentamicin, 17.64 % to tetracycline, 14.28 % to nalidixic acid, and 10 % to chloramphenicol. All isolates were susceptible to ciprofloxacin. One Salmonella Corvallis isolate recovered from a patient with chronic hemolytic anemia produced an ESBL and its PFGE profile demonstrated less than 96 % similarity to fecal and wound Salmonella Corvallis with susceptible phenotypes. S. enteritidis was the most common cause of systemic and

    Pyridoxine-dependent epilepsy (PDE) is a rare autosomal recessive disorder characterized by intractable seizures in neonates and infants. The seizures cannot be controlled with antiepileptic medications but respond both clinically and electrographically to large daily supplements of pyridoxine (vitamin B6). PDE is caused by mutations in the ALDH7A1 gene. Molecular genetic analysis of the ALDH7A1 gene was performed in seven patients, referred with clinical diagnosis of PDE. Mutations were detected in a dizygotic twin pair and a non-related boy with classical form of PDE. Direct sequencing of the ALDH7A1 gene revealed one novel (c.297delG, p.Trp99*) and two already reported (c.328C>T, p.Arg110*; c.584A>G, p.Asn195Ser) mutations. Here, we report the first genetically proven cases of PDE in Bulgaria.

    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.

    In the framework of selecting a suitable site for final disposal of low- and intermediate level short-lived radioactive waste (LILW-SL) in Bulgaria, site characterization is ongoing at the Marichin Valog site, North-West Bulgaria. The site is characterized by a complex sequence of loess, clayey gravel, and clay layers, of which the first 30-40 m are unsaturated. Proper knowledge about unsaturated water flow and concomitant radionuclide transport is key input to safety assessment calculations. Constant-head infiltrometer tests were carried out at several meters below ground surface to determine the unsaturated hydraulic properties of silty loess, clayey loess, and clayey gravel layers. Individual infiltrometers were equipped with 0.5-m-long filter sections; the shallowest filter was from 2 to 2.5 m depth, whereas the deepest was from 9.5 to 10 m depth. Infiltration tests provided data on cumulative infiltration and progression of the wetting front in the initially unsaturated sediments surrounding the infiltrometer. A cylindrical time-domain reflectometry TRIME probe was used to measure water content variations with time during progression of the wetting front. Access tubes for the TRIME probe were installed at 0.3 to 0.5 m from the infiltrometer tubes. By means of an inverse optimization routine implemented in the finite element code HYDRUS-2D, field-scale soil hydraulic parameters were derived for all layers. Results show a great consistency in the optimized parameter values, although the test sites were several meters apart. Apparently the size of the affected volume of soil was large enough to reduce the effect of spatial variability and to produce average field-scale hydraulic parameters that are relevant for large-scale predictions of flow patterns and radionuclide migration pathways.

    Background Rotavirus (RV) causes a high proportion of acute gastroenteritis (AGE) cases, especially among children under the age of five years old. This surveillance study was undertaken to study the incidence and severity of rotavirus gastroenteritis (RVGE) in primary care settings in Bulgaria over a one-year period. Methods In this prospective, observational study of AGE cases in children under five years of age presenting in the primary care setting over a one year period, stool samples were collected and tested for RV using a rapid visual immunochromatographic test kit. After the first visit, parents monitored their child for about two weeks and reported the symptoms experienced by the child during the follow-up period to the physician in a follow-up phone call. The percentage of RVGE cases among AGE was calculated and the severity of AGE (according to the 20-point Vesikari scale) was assessed by the physician based on the symptoms reported by the parents. The seasonality of RVGE was also studied. Results The proportion of RVGE among the 624 AGE cases examined was 25.5%. Severe AGE was experienced by 81.8% RV-positive and 54.6% RV-negative children (p-value <0.001) and a third of all severe AGE cases occurred in RV-positive patients. A multivariate logistic regression analysis of the determinants of hospitalization indicated that severity of disease and RV-positivity were the statistically significant variables explaining hospitalization of AGE cases; even controlling for severity, RV-positive patients were more often hospitalized than RV-negative ones. RVGE cases occurred throughout the year, with peaks during August and September. Conclusion Our study emphasizes that RV is an important cause of AGE in children under five presenting in primary care settings in Bulgaria and a disproportionately high proportion of severe AGE cases may be attributed to RV infections.

    OBJECTIVE: To assess the incidence of meningitis caused by Haemophilus influenzae type b (Hib) among children in Bulgaria and to provide evidence for an informed decision on the use of Hib vaccines in Bulgaria. METHODS: From 1 July 1997 to 31 December 1999, active surveillance for meningitis was conducted in six regions. For children with suspected meningitis, a cerebrospinal fluid (CSF) specimen was sent for cytology, chemistry, latex agglutination testing, culture and sensitivity. FINDINGS: During the 2.5-year study period, surveillance was conducted among 138 249 children aged <5 years - a sample representing 40% of all Bulgarian children in this age group. Overall, 285 children with suspected meningitis were identified. In eight children, clinical symptoms of meningitis resolved rapidly before a CSF specimen could be obtained. Of the remaining 277 children, 121 (44%) were classified as having probable bacterial meningitis on the basis of a CSF examination. An organism was identified for 88 (73%) of the 121 cases with probable bacterial meningitis. There were 21 cases of Hib, giving a mean annual incidence of 6.1 Hib meningitis cases per 100 000 children <5 years; the case-fatality rate was 10%. Nearly 60% of Hib isolates were resistant to one or more antibiotics, but they were not resistant to third-generation cephalosporins. CONCLUSION: On the basis of these findings, Hib conjugate vaccines have been included in the list of vaccines recommended for children by the Bulgarian Ministry of Health. The recommended initial treatment for paediatric bacterial meningitis has been changed to third-generation cephalosporins. PMID:12378285

    The first part of this study deals with the available information (date, time, location) of 57 thunderstorms with tornado or with waterspout (9 of which have evolved near the Black Sea coast and 4 are formed over dams). These are about all cases that have been reported in Bulgaria between 1956 and 2010. About half of all tornadoes (49%) that occurred in land are formed over mountainous or hilly terrain and usually move over the near river valleys. Almost all tornado events occur during the warm half of the year with maximum in June, when about 25% of all tornado storms take place. There are only 4 cases from the cold half of the year - 1 in December, 1 in February, and 2 in March. The second part of the paper gives some basic analysis of two severe thunderstorms, connected with the development of tornado events. The typical synoptic situation associated with the formation of a tornado is a slow-moving cold atmospheric front with meridional stretch. It should have bigger than usual temperature gradient between the cold and the warm air masses. A less common synoptic scale structure that leads to the formation of tornado is an upper-air summer low centred over the Black Sea. The first analysed storm is a “winter” case. The tornado occurred in South-central Bulgaria on 24 March 2004. The other one is a typical “summer” case. It occurred in the north-west of the country on 2 June 2009. The data and information that are used in these analyses come from classic meteorological observations, radar images, records from post-event in-situ field investigation as well as various media sources. The characteristics of these tornadoes give us reason to classify them as moderate (class F2 according to the Fujita scale).

    This study examines ethnic, national, familial, and religious identity and well-being of 632 Roma minority and 589 majority adolescents (age: M = 15.98 years, SD = 1.34) in Bulgaria, the Czech Republic, Kosovo, and Romania. Results indicated that Roma showed lower endorsement of national identity but stronger religious identity than their majority counterparts. Path models showed positive associations of familial and religious identities with well-being, whereas Roma identity was negatively associated with well-being, particularly for Roma in Bulgaria and Kosovo (countries with a less active policy toward improving conditions of Roma). In the latter countries, Roma ethnic identity is less relevant and weakly associated with psychological well-being of youth.

    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

    Species composition and prevalence of the blood parasites of three migratory Acrocephalus species of warblers (Acrocephalus arundinaceus, Acrocephalus scirpaceus and Acrocephalus schoenobaenus) were studied during spring period in Bulgaria. For each of the studied species, we compared the parasite fauna during their spring migration at three study sites in search of infection patterns in time and space. Spatial differences were registered in the blood parasites and their prevalence for two of the studied species-A. arundinaceus and A. scirpaceus, whereas for the third one-A. schoenobaenus, there were no significant differences. The parasite species Haemoproteus belopolskyi was present in migrating A. arundinaceus only at Kalimok station, but not at the other two sampling locations. Plasmodium prevalence in A. arundinaceus migrating through Kalimok was also different between years. A decrease of H. belopolskyi prevalence was detected for A. schoenobaenus at Petarch during the spring of 2006. On the contrary, Plasmodium (Haemamoeba) sp. infections of the same bird species increased during the spring period. The differences found between sites could be explained with the different origin of the migrants at different migration stopover points. Climatic conditions and vector abundance in the zones of origin are probable reasons for the observed differences between years.

    A water-soluble polysaccharide (BIWS-4b) was purified from the fruit bodies of Bulgaria inquinans (Fries). It is composed of mannose (27.2%), glucose (15.5%) and galactose (57.3%). Its molecular weight was estimated to be 7.4 kDa (polydispersity index, Mw/Mn: 1.35). Structural analyses indicated that BIWS-4b mainly contains (1 → 6)-linked, (1 → 5)-linked and (1 → 5,6)-linked β-Galf units; (1 → 4)-linked and non-reducing terminal β-Glcp units; and (1 → 2)-linked, (1 → 6)-linked, (1 → 2,6)-linked and non-reducing terminal α-Manp units. When examined by the 4-day method and in a prophylactic assay in mice, BIWS-4b exhibited markedly suppressive activity against malaria while enhancing the activity of artesunate. Immunological tests indicated that BIWS-4b significantly enhanced macrophage phagocytosis and splenic lymphocyte proliferation in malaria-bearing mice and normal mice. The anti-malarial activity of BIWS-4b might be intermediated by enhancing immune competence and restoring artesunate-suppressed immune function. Thus, BIWS-4b is a potential adjuvant of anti-malaria drugs. PMID:21785644

    Past emissions from a non-ferrous smelter at Kuklen, near Plovdiv, in Bulgaria have resulted in very high concentrations of heavy metals, in particular Cd and Pb, in agricultural soils close to the plant. An interdisciplinary research project, initiated under the auspices of the EU INCO-Copernius programme, has included investigation of the principal processes by which the heavy metals are being transferred from the contaminated soils to the children of the village who have abnormally high Cd and Pb blood concentrations. The primary source of Pb in blood is the land close to the smelter which bas elevated concentrations of Pb and which is used to grow food and fodder for livestock. Fodder with Pb concentrations as high as 48 mg/kg is consumed directly by the animals resulting in high Pb concentrations in livers and kidneys. These are then consumed by the human population. The evidence clearly indicates this to be one route of transfer through the food chain. Other, more direct, routes, e.g the use of flour prepared from locally produced grain or the direct ingestion of dust from school playgrounds, the street and homes, may also play an important role.

    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. PMID:25143963

    The synmetamorphic nappe system of the Rhodope Metamorphic Complex has been deformed into dome-and-basin structures attributed to syn- to post-convergent exhumation. We document the deformation style and present new thermobarometric and geochronological constraints for the Kesebir-Kardamos dome in southern Bulgaria and northern Greece. The dome consists of a migmatitic core overlain by high-grade thrust sheets. Kinematic indicators indicate a continuum from ductile to brittle conditions during exhumation. Thermodynamic modeling applied to the high-grade, intermediate thrust sheets yielded peak conditions of 1.2 GPa and ca 730 °C. New U-Pb SHRIMP-II dating of zircons from rocks of the same unit revealed Late Jurassic-Early Cretaceous (145 Ma) as the time of metamorphic crystallization; some zircon rims yielded Eocene ages (53 and 44 Ma) interpreted as having been thermally reset owing to coeval granitoid magmatism. The high-grade rocks were covered by Lutetian-Priabonian marine sediments after exhumation. Slumps suggest that sedimentation took place in a tectonically active environment. Our new structural, petrological and geochronological results suggest that the major shear zone in the core of the Kesebir-Kardamos dome is equivalent to the Late Jurassic-Early Cretaceous Nestos Shear Zone. Post-Jurassic metamorphic ages recorded in the Rhodope most likely represent crustal rather than deep subduction geodynamic processes.

    Between August and November 2009, eight cases of classical swine fever (CSF) occurred in young wild boar in a 25-km2 oak forest3 km south of the river Danube in the north-eastern part of Bulgaria. The wild boar population within the affected area was estimated to be 156 animals, or approximately six boar per km2. To control and eradicate the disease, and in addition to vaccination and hunting, trapping was used to reduce the boar population to below two animals per km2. In total, 124 wild boar were removed from the infected area within three months. Of these, 119 were trapped. In this paper, the authors present trapping as a successful tool to eradicate CSF from an area where hunting and vaccination alone might not be sufficient. Up to seven wild boar could be trapped in a single trap. Furthermore, the spread of CSF virus to the local domestic pig population and to wild boar in neighbouring areas was prevented. By decreasing the wild boar population to fewer than two animals per km2, it was assumed that the virus would no longer circulate and the disease would fade out. In fact, no further CSF cases were diagnosed afterwards. Under Bulgarian and similar conditions, trapping seems to be a more reliable method than hunting for reducing a wild boar population within a short period of time. Furthermore, trapping may be used alone or in combination with hunting, depending on the situation.

    Examination of specimens collected from water shrews Neomys fodiens in the Rhodope Mountains, Bulgaria, revealed a new species of Soricinia. Soricinia genovi n. sp., is described and the syntype of Soricinia globosa (the only other Soricinia species known from Neomys) is redescribed. The new species differs from S. globosa in the number of proglottids, relative length of the cirrus-sac, number of eggs in gravid proglottids, absence of vaginal sphincter and other characters. Among Soricinia, parasitic in shrews of the genus Sorex, the new species is most similar to Soricinia quarta. Soricinia genovi can be distinguished from S. quarta by the length of the cirrus-sac, larger testes and ovary, position of vitellarium and armament of cirrus. Comparison of nuclear ribosomal 28S DNA sequences and mitochondrial nad1 sequences clearly distinguishes S. genovi sp. n. from S. quarta, Soricinia bargusinica and Soricinia infirma. The levels of interspecific sequence divergence among Soricinia species exceed those reported for some other hymenolepidids of mammals. Phylogenetic analysis places S. quarta and S. genovi sp. n. as the closest taxa which is in agreement with morphological evidence. Our data suggest that the specimens of Soricinia from the Altai Mountains that were morphologically closest to S. infirma represent a new species. Pairwise sequence comparisons and phylogenetic analysis also indicate that "S. infirma" group may constitute a genus separate from the remaining Soricinia.

    The major tectonic elements of northern Bulgaria are the east-west-trending Balkan-Forebalkan fold belt and the Moesian platform. Moderate hydrocarbon exploration potential exists in trapping geometries generated during the tectonic evolution of the region coupled with reservoir/seal pairs and source rocks within Mesozoic strata. The tectonic evolution of the region includes Early Triassic to Early Jurassic intracratonic rifting followed by multiphase compression that contracted the rift basin and produced a north vergent fold and thrust belt along the southern margin of the stable Moesian platform. Compression began during the Early Cretaceous, continued during the Paleocene, and concluded during the middle Eocene. Trap types generated during the tectonic evolution include normal fault-bounded rotated blocks in the autochthonous section and elongate, asymmetric anticlines in the allochthonous section. Triassic to Upper Jurassic Marine facies were deposited in an east-west-trending rift. Sediments deposited in a shallow foredeep, which evolved during Lower cretaceous compression, overlay the rift sequence. The Early Mesozoic rift sequence provides the depositional settings for Middle Triassic and lower Middle Jurassic source rock shales and sandstone/carbonate reservoirs ranging from Middle Triassic to Lower Cretaceous. Carbonate reservoirs generally are porous dolomites with intercrystalline, moldic, and vugular pore types interbedded with nonporous limestones. Clastic reservoirs are quartz-rich sandstones with pore types that are reduced intergranular, dissolution, and microporosity. These heterogeneous reservoir targets exhibit poor to good reservoir characteristics and are overlain with sealing lithologies of variable thicknesses.

    The Hungarian geographer, archaeologist, and ethnographer Kánitz Félix, great friend and admirer of the Bulgarian people has left valuable and comprehensive information about North Bulgaria and the Balkan Mountain by the end of the Ottoman oppression in his work La Bulgarie Danubienne et le Balkan (1882). The book contains also valuable references concerning the animal breeding activities within the 1860-1880 period in this part of the world. In the mountainous region in Bulgaria sheep- and goat-breeding were well developed, and this accounted to a large extent for the destruction of forests. Numerous and large flocks of sheep were raised in Dobrouja, a portion of which belonged to the famous shepherds of the town of Kotel. During the winter season a great number of flocks from Transylvania were also kept in this region. The breeding of sheep was the main source of meat supply both for North Bulgaria and the Balkan Mount region and for the markets of the Ottoman Empire. It also yielded a total of 120,000 okas of wool (78 okas = 100 kg) annually to meet the needs of the Empire manufacture as centered at that time in the town of Sliven for the production of textiles for the army. The raising of cattle was also prosperous during the same time. On the other hand, stock breeding was unfavourably influenced by heavy taxing in the form of both cash payment and remuneration in kind, by requisitioning (especially in war time) and the endless thefts and robberies done by tatars and cherkesses that had moved to this country from Caucasus. This exploitation concerned equally Bulgarian and Turkish animal breeders.

    In this work, we present results of two-wavelength lidar observations on Saharan dust layers over Sofia, Bulgaria, in two days of strong dust intrusion events in the fall and winter of the year 2010. Measurements are carried out at two wavelengths (1064 nm and 532 nm) by using two channels of an aerosol lidar based on a frequency-doubled Nd:YAG laser. Optical, dynamical, and microphysical properties of the dust layers are studied and analyzed, distinguishing specifics of coarse and fine aerosol fractions. The spatial-temporal evolution of atmospheric aerosol/dust density fluctuations is shown on height-time coordinate color-map plots for each of the two wavelengths. Time-averaged height profiles of the atmospheric backscattering coefficient at 1064 nm and 532 nm are presented, showing the dust and aerosol density distribution up to about 10 km AGL, with a range/height resolution of 15/8 m. Microphysical properties of dust and aerosol particles are characterized qualitatively by using backscatter-related Ǻngström exponents (BAE). Range-resolved time-averaged height profiles of BAE are shown, particularly for the dust layers, indicating the dominating particle size-modes. Obtained BAE values in the range 0.2-0.5 are typical for desert mineral dust, suggesting coarse particles in the over-micron size range. Frequency-count analysis of the obtained BAE arrays is performed for typical separate dust-containing layers, revealing distributions and changes of particle size modes in terms of BAE, as well as effects of dust mixing with finer urban and industrial aerosols. Some efforts are devoted and focused on characterizing the temporal dynamics of the range distribution and density of dust and aerosols. Peculiarities of spatial distribution, size composition, and temporal evolution of Saharan dust aerosols are revealed, analyzed, and discussed.

    Abstract An unknown species belonging to the genusCalcaridorylaimus Andrássy, 1986 was collected from the litter of broadleaf forests dominated by Castanea sativa Mill. and mixed with Quercus daleshampii Ten. and Fagus sylvatica L. on Belasitsa Mountain, south-western Bulgaria. Calcaridorylaimus castaneae sp. n. is characterised by its long body (1.4–2.1 mm), lip region practically not offset, vulva transverse, short odontostyle (14.5–16 μm) and tail (75.5–110.5 μm, c=14.7–23.6; c’=2.9–4.4) in females and 38–46 μm long spicules with small spur before their distant end in males. It is most similar to C. andrassyi Ahmad & Shaheen, 2004, but differs in having transverse vs pore-like vulva and shorter spicules (38–46 μm vs 52–57 μm). An identification key to the species of the genus Calcaridorylaimus is proposed. Phylogenetic analyses were performed on 18S and D2-D3 expansion domains of 28S rRNA genes by Neighbor-Joining, Maximum Likelihood and Bayesian Inference methods. The phylograms inferred from 18S sequences showed closest relationships of the new species with some species belonging to the genus Mesodorylaimus. However, insufficient molecular data for members of both genera do not allow the phylogenetic relationships of Calcaridorylaimus and the new species described herein to be elucidated. PMID:24899849

    This study was carried out on 104 workers at three work operations and a control (nonproduction) area, within a methyl methacrylate (MMA)/polymethyl methacrylate (PMMA) production facility in Bulgaria. Airborne monitoring was conducted over a 10-year period for MMA and the reactant chemicals methanol and acetone cyanhydrine at the MMA operation, and MMA was monitored at the PMMA operation. Acid-base status of the workers was evaluated using traditional criteria (pH, pCO(2), pO(2), and HCO(3) in plasma). Data from retrospective monitoring of air levels of the chemicals were compared with the acid-base status of workers at the plant. In some cases air concentrations exceeded the threshold limit value, with the highest percentage of overexposure occurring with airborne MMA in the PMMA production operation. Acid-base disruption indicated by reductions in plasma pH and HCO(3) was found for all groups except the control population. The highest percentage reduction was associated with PMMA production workers. Additionally, respiratory acidosis, indicated by increased pCO(2), was noted in the MMA production and maintenance groups, implying that the response to MMA exposure may involve both the metabolic and respiratory acidosis component. This study was unique in that the combined exposure to MMA and the precursor chemical (methanol) were shown to produce the same effects in workers. It is suggested that when combined exposure occurs, disruption of acid-base status may occur. Enforcement of PPM requirements for coveralls and gloves should prevent skin contamination. Additionally, improvement of equipment in MMA and PMMA production areas is recommended: (1) automation of some manual operations; (2) use of respiratory protection during equipment cleaning; and (3) installation of local ventilation when applicable.

    Abstract A description is provided of Longidorus cholevae sp. n., a bisexual species associated with wild cherry (Prunus avium L.) from the Rila Mountains, Bulgaria. The position of L. cholevae sp. n. among other species of the genus was elucidated by using morphological and molecular data. Phylogenetic analyses were performed of D2-D3 expansion domains of the 28S rRNA and the partial ITS1 containing regions by Neighbor-Joining, Maximum Likelihood and Bayesian Inference methods. The species is characterised by a female body length of 6.1–8.1 mm; long odontostyle (106–129 μm); lip region wide (21.5–24 μm) rounded and continuous with the body profile; amphidial pouches short and wide, funnel-shaped; a posteriorly situated guide ring (30–37 μm); normal arrangement of pharyngeal glands, and short bluntly rounded to hemispherical tail. Four juvenile stages indentified, first stage with elongate conoid tail. Males with 2–4 adanal pairs and a row of 11–13 single ventromedian supplements, spicules 96–120 μm long. Based both on morphological and molecular data the new species appearred to be the most similar witha group of species distributed in Europe sharing common charcters such as amphidial fovea, lip region and tail shapes, and having similar odontostyle and body length: L. poessneckensis, L. caespiticola, L. macrososma, L. helveticus, L. carniolensis and L. pius. An updated list of Longidorus species and a partial polytomous keys to the Longidorus species with long odontostyle (code A45) and short tail (code H1) are provided. PMID:24146553

    Here, we report the circulation of highly related virulent Newcastle disease viruses (NDV) in Bulgaria and Ukraine from 2002 until 2013. All of these NDV isolates have the same virulence-associated cleavage site ("113RQKR↓F117"), and selected ones have intracerebral pathogenicity index values ranging from 1.61 to 1.96. These isolates are most closely related to viruses circulating in Eastern Europe, followed by viruses isolated in Asia during the same period of time. Interestingly, the majority of the viruses were isolated from backyard poultry, suggesting the possibility of a "domestic" or "urban" cycle of maintenance. The molecular characterization of the nucleotide sequence of the complete fusion protein gene of the studied viruses suggests continued circulation of virulent NDV of sub-genotype VIId in Eastern Europe, with occasional introductions from Asia. Furthermore, the high level of genetic similarity among those isolates suggests that the NDV isolates of sub-genotype VIId from Bulgaria and Ukraine may have been part of a broader epizootic process in Eastern Europe rather than separate introductions from Asia or Africa. The continuous monitoring of backyard poultry flocks for the presence of circulating virulent NDV strains will allow early identification of Newcastle disease outbreaks.

    Sentimentality and nostalgia are two similar psychological constructs, which play an important role in the emotional lives of elderly people who are usually focused on the past. There are two objectives of this study - making cross-cultural comparison of sentimentality and nostalgia among Bulgarian and Greek elderly people using a questionnaire, and establishing the psychometric properties of this questionnaire among Greek elderly people. Sentimentality and nostalgia in elderly people in Bulgaria and Greece were studied by means of Sentimentality and Nostalgia in Elderly People questionnaire (SNEP), created by Gergov and Stoyanova (2013). For the Greek version, one factor structure without sub-scales is proposed, while for the Bulgarian version of SNEP the factor structure had four sub-scales, besides the total score. Together with some similarities (medium level of nostalgia and sentimentality being widespread), the elderly people in Bulgaria and Greece differed cross-culturally in their sentimentality and nostalgia related to the past in direction of more increased sentimentality and nostalgia in the Bulgarian sample. Some gender and age differences revealed that the oldest male Bulgarians were the most sentimental. The psychometric properties of this questionnaire were examined for the first time in a Greek sample of elders and a trend was found for stability of sentimentality and nostalgia in elderly people that could be studied further in longitudinal studies.

    We describe here the results of respiratory syncytial virus (RSV) detection by reverse transcription polymerase chain reaction (RT-PCR) during two consecutive seasons, from December 2006 to February 2007 and from October 2007 to March 2008, performed in the National Laboratory of Influenza and Acute Respiratory Diseases, Bulgaria. A total number of 278 nasopharyngeal samples obtained from hospitalised children up to the age of five years were investigated for these two seasons. During the first season, the aetiological role of RSV was confirmed in 56 of 148 samples (37.8%) compared to 11 of 130 samples (8.5%) during the second season. Since the beginning of January 2008, RT-PCR for the detection of the recently identified human metapneumovirus (HMPV) has also been introduced in Bulgaria. This virus has been demonstrated as the aetiological agent in 13 out of 81 samples (16%) from children of the same age group. The use of RT-PCR allows the detection of a broader spectrum of viruses causing respiratory diseases, as well as better discrimination of the aetiological agents in clinically similar cases.

    The exposure and risk evaluation process in Bulgaria concerning non-ionizing radiation health and safety started in the early 1970s. Then, the first research laboratory "Electromagnetic fields in the working environment" was founded in the framework of the Centre of Hygiene, belonging to the Medical Academy, Sofia. The main activities were connected with developing legislation, new equipment for measurement of electromagnetic fields, new methods for measurement and exposure assessment, in vivo and human studies for developing methods, studying the effect of non-ionizing radiation on human body, developing exposure limits. Most of the occupations as metal industry, plastic welding, energetics, physiotherapy, broadcasting, telephone stations, computer industry, etc., have been covered by epidemiological investigations and risk evaluation. In 1986, the ANSI standard for safe use of lasers has been implemented as national legislation that gave the start for studies in the field of risk assessment concerning the use of lasers in industry and medicine. The environmental exposure studies started in 1991 following the very fast implementation of the telecommunication technologies. Now, funds for research are very insignificant, and studies in the field of risk assessment are very few. Nevertheless, Bulgaria has been an active member of the WHO International EMF Project, since 1997, and that gives good opportunity for collaboration with other Member states, and for implementation of new approach in the EMF policy for workers and people's protection against non-ionizing radiation exposure.

    The paper aims to investigate the capabilities of using high-resolution satellite images: panchromatic WorldView-1 satellite image acquired on 30/11/2011 and multispectral QuickBird-2 satellite image acquired on 31/05/2009 for crop analysis, which includes crop identification, crop condition assessment and crop area estimates applications in Bulgaria using the power and flexibility of ERDAS IMAGINE tools. The crop identification was accomplished using unsupervised and supervised classification processing techniques using as reference ground data. After the supervised classification, fuzzy convolution filter was applied to reduce the mixed pixels using ERDAS Imagine software. Accuracy totals, error matrix and kappa statistics were calculated using accuracy assessment tool in ERDAS Imagine to assess the quality of the classification process. Crop condition assessment was accomplished using the derived Normalized Difference Vegetation Index (NDVI) image from the QuickBird-2 image, which was reclassified and was given meaningful estimations on the crop condition. Crop area was estimated using pixel counting approach. Pixel counting methods are known for introducing bias to the crop area estimates but using the high Overall Accuracy of 90.86% and overall Kappa Statistics of 0.8538 for the classified QuickBird-2 image and Overall Accuracy of 86.71% and overall Kappa Statistics of 0.7721% for the classified WorldView-1 allows that option to be utilized according to (Gallego, 2004). As a conclusion it can be stated that using the benefits that high-resolution satellite images gives in combination with the power and flexibility of ERDAS Imagine tools, crop identification can be achieved more accurately by increasing the identification accuracy and also by having the necessary ground information for selecting appropriate training samples. Crop identification by applying an arable mask is better practice, because it is reducing the mixed pixels problem i.e. also known as

    The Cold War Era left the major participants, the United States and the former Soviet Union (FSU), with large environmental legacies in terms of facility contamination and environmental degradation. Although the countries face similar issues from similar activities, important differences in waste management practices make the potential environmental and health risks of more immediate concern in the FSU and Eastern Europe. In the West, most nuclear and chemical waste is stored in known contained locations, while in the East much of the equivalent material is unconfined, contaminating the environment. The knowledge and experiences of the U.S. in these initial cleanup efforts are seen as important information in many North Atlantic Treaty Organization (NATO) Partner countries, where the environmental problems are more severe and the cleanup budgets more limited. An Advanced Study Institute (ASI) on ''Risk Assessment Activities for the Cold War Facilities and Environmental Legacies'' was held in Bourgas, Bulgaria, May 2-11, 2000. The objective of the ASI was to provide information to facilitate and enable decision-making activities affecting the environment and human populations in the NATO and Partner countries. Specifically, the ASI provided a forum to communicate the current status of risk analysis and management methodologies and their appropriate application. It addressed scientific approaches and application experiences from the initial U.S. risk assessment activities. This book is the product of the ASI. The power of the text lies in linking information on legacies with an integrated view of controlling the risk of those legacies. Risk can only be effectively controlled by proper balance of three central concepts: risk analysis, risk perception, and risk management. The editors were drawn together by the joint recognition that risk analysis methods had matured over the past 30 years in several fields, relatively independent of each other. It was time to

    In the area of Pobiti Kamani (Varna, northeast Bulgaria), massive carbonate cemented columns ("chimneys", up to 1.5 m diameter and 8 m high) and horizontal interbeds (≤ 1.5 m thickness) occur in dispersed outcrops over an area of 70 km 2 within loose Lower Eocene sands. Field observations and petrographical and stable isotope geochemical characterisation of four studied locations reveal a relationship between these structures and processes of ancient hydrocarbon seepage. Column and interbed structures both consist of similar well-sorted silt- to sand-sized nummulitic host sediments, predominantly cemented by early diagenetic, low-magnesium calcite. Filamentous textures, about 10 μm in diameter and 80-650 μm long, are only locally detected within interparticle calcite cement of columns. Column samples from two sites reveal a similar, linear and inverse covariant trend of δ13C- δ18O values, which was interpreted as a mixing trend between two end member fluid/precipitation conditions, i.e. (1) a methane- and/or higher hydrocarbon-derived carbon member characterised by δ13C values as low as - 43‰ and marine controlled precipitation conditions with δ18O of - 1 ± 0.5‰ V-PDB and (2) a member with less contribution of methane which was mixed most likely with less depleted carbon sources explaining δ13C values ranging up to - 8‰ V-PDB. The corresponding, depleted δ18O values, with many samples clustering around - 8‰ V-PDB, are interpreted in terms of precipitation at elevated temperatures. This suggests the venting system was not a true "cold" seep, sensu stricto. Furthermore, column cross-transects often document an internal pattern consisting of (concentric) zones with distinct isotopic signatures, which vary between the two end members. The mixing and internal pattern of column isotopic data, together with petrographical observations, are qualitatively interpreted as evidence of alternating precipitation conditions, controlled by varying seepage rates

Two problems of special interest are explored: whether the leading principles of fundamental ethical codes are presented in CPEB and whether the code itself is relevant to the current medical professional and social situation in the country. The conclusion reached after a step-by-step analysis is that CPEB attempts to cover a wide range of principles and problems in medical practice and corresponds with the fundamental ethical codes. Although the code is criticized in some points, it could be very useful, provided that it is well publicized in the profession.

    The essential oil of long-time stored seeds of dill (Anethum graveolens L.) from Bulgaria was analyzed by physicochemical methods, gas chromatography (GC), GC-mass spectrometry (MS) (achiral and chiral phases), and olfactometry, and its antimicrobial activity was tested by using different strains of microorganisms. More than 40 constituents of the essential dill oil, obtained from seeds stored for more than 35 years, could be identified as essential volatiles, responsible for the pleasant fresh (D-limonene) and spicy (D-carvone) odor of a high quality. As aroma impact compounds, D-carvone (50.1%) and D-limonene (44.1%) were found. Antimicrobial testings showed high activity of the essential A. graveolens oil against the mold Aspergillus niger and the yeasts Saccharomyces cerevisiae and Candida albicans.

    Canine vector-borne diseases (CVBDs) have increasingly become a focus of interest in recent years. Some of the CVBDs are zoonotic and may therefore also represent a risk for the human population. Different factors are in discussion to explain the expansion of vectors and pathogens into formerly unaffected areas. Knowledge of the prevalence and distribution of CVBDs in Bulgaria is scant overall and most data rely on single case descriptions. The aim of the present study was to determine the seroprevalence of important CVBDs in 167 dogs from central-southern Bulgaria (Stara Zagora), with special emphasis on hitherto uninvestigated babesiosis and angiostrongylosis, on poorly investigated Lyme borreliosis and canine granulocytic anaplasmosis, and on the potentially zoonotic dirofilariosis and leishmaniosis. Relatively high prevalence rates were documented for anti-Babesia canis antibodies, Dirofilaria immitis antigen (16.2 %; 27/167 each), anti-Ehrlichia canis (21 %; 35/167) and anti-Anaplasma phagocytophilum antibodies (30.5 - 46.1 %; 51 - 77/167), while Borrelia burgdorferi seroprevalence was low (2.4 %; 4/167). All samples were negative for Leishmania infantum antibodies and Angiostrongylus vasorum antigen and antibodies. In total, 64.7 % (108/167) of the samples indicated infection or exposure to at least one agent and a high proportion of dual infections (39.8 %; 43/108) was demonstrated. Multiple infections with up to four different organisms were also detected. Our data underline the importance of CVBDs and especially of co-infections which could influence the clinical outcome in dogs.

    Roma (Gypsies), the largest and most disadvantaged ethnic minority group in Europe, are believed to be vulnerable to HIV/AIDS. This study's aim was to examine HIV risk in 6 Roma male sociocentric networks (n = 405 men) in Bulgaria. Participants were interviewed concerning their risk practices and tested for HIV/STDs. High-risk sexual behaviors were common. Over 57% of men had multiple sexual partners in the past 3 months. Over one-third of men reported both male and female partners in the past year. Condom use was low. Greater levels of sexual risk were associated with lower intentions and self-efficacy for using condoms, drug use, having male partners, knowing HIV-positive persons, and having higher AIDS knowledge but no prior HIV testing. Two men had HIV infection, 3.7% gonorrhea, and 5.2% chlamydia. HIV prevention interventions directed toward high-risk social networks of Roma are needed before HIV infection becomes more widely established.

    This study presents data from a molecular survey of the species of the genus Culicoides from the region of Kalimok Field Station (NE Bulgaria) and haemosporidian parasites occurring in them in order to investigate the host-parasite specificity of haemosporidians to their dipteran vectors. The identification of Culicoides spp. was carried out by morphological and molecular-genetic methods. We collected and analysed 230 individuals of the genus Culicoides. Nine species were found. Eight species were identified morphologically; Culicoides obsoletus, C. riethi, C. newsteadi, C. circumscriptus, C. festivipennis, C. punctatus, C. pictipennis and C. puncticollis. The ninth species might be classified as either of C. nubeculosus or C. riethi and its identification needs additional investigations. The total prevalence of Haemoproteus in the examined biting midges was 2.17%. Three individuals of C. pictipennis were infected with the Haemoproteus lineage TURDUS2 (prevalence 16.67%), a common parasite of thrushes (Turdidae). Two individuals of C. circumscriptus contained Haemoproteus lineages (prevalence 2.78%); these were the lineage HAWF2 (previously reported from Coccothraustes coccothraustes) and a new lineage CULCIR1 not previously reported in the literature.

    Following a foot-and-mouth disease (FMD) case of serotype O in wild boar in Southeast of Bulgaria, notified in January 2011 and eleven FMD outbreaks in livestock, a control and eradication plan according to the EU legislation was implemented. Based on the epidemiological considerations a "Cordon Sanitaire" along the border to Turkey, consisting of a defined infected area (1240 km(2)) and two areas of risk (2160 km(2)) was established. Within these areas a total of 812 wild boar, 68 roe deer, 7 red deer and 2 mouflons, hunted between February 2011 and January 2012, were tested for the presence of FMD. No FMD virus could be detected. Seropositive animals were found in wild boar (6.9%) and roe deer (4.4%), most of them spatially clustered around the FMD outbreaks in livestock, limited within a radius of 20 km. The outbreaks in domestic ungulates were controlled in the framework of EU legislation, including stamping out, standstill and no use of vaccination. All villages within the Cordon Sanitaire were examined for the presence of FMD according to the control and eradication plan. Neither clinical signs nor seroconversion was detected and the region could regain its status of FMD freedom without vaccination. The relatively low seroprevalence and clustered spatial distribution of seropositive wild boar and roe deer suggest that the FMD infection in wildlife was mainly a short living event, which failed to develop into a large scale epidemic.

    In this paper we consider the possibility of using remote sensing data for determining various negative factors affecting archaeological objects condition on the territory of the Republic of Tatarstan. Fortified settlements, with the system of defensive fortifications, were selected as the objects of study, as they are easily identified by remote sensing data. In our view, the analysis of medieval Volga Bulgars (X-XIII centuries A.D.), the most common in the territory of the Republic of Tatarstan, has the highest priority. The first task by using remote sensing was to obtain actual data on the current condition of archaeological monuments located on the Kuibyshev reservoir shore, where the threat of destruction is maximized. Due to the fact, that most of the Volga-Bulgaria settlements, is located on the small rivers banks, the second task was geomorphological description of monuments placement in order to assess the risk of their destruction by natural processes. Third objective was to evaluate the role of the human factor in archaeological sites destruction. Ancient settlements under different types of negative impact were selected for the study. Deciphering of multitemporal remote sensing data allowed to assess the objects condition and to predict the risk of further damage. Additionally, it made able to correct the form of the Bulgars hillforts in comparison with existing plans, as well their size and location in the landscape, to restore the original appearance of destroyed fortified settlements, to determine precise coordinates for the further use of these data in the archaeological geographic information systems.

    Two-wavelength (1064/532 nm) lidar observations of long-range transported Saharan dust present in the atmosphere over Sofia, Bulgaria, during a 4-day dust intrusion event in winter 2010, are reported. Aged desert aerosols are detected at altitudes up to 4 km above the sea level, within and above the boundary layer as mixed with other aerosols-representing the particular case under consideration. Optical, microphysical, and dynamical properties of dust aerosols are obtained and analyzed. Special attention is paid to retrieving and vertical profiling of dust backscatter-related Ångström exponents (BAEs), as well as to determining their frequency-count distributions. Obtained BAE values in the range 0.3 to 0.6 (±0.2) indicate domination of coarse particles in the near overmicron size range. Reasonability of coarse-mode-dominated dust size composition is substantiated, based on measurement and transportation-history analysis. The performed frequency-count statistics reveals dust BAE distributions asymmetrically extended to multimode distribution shapes, resulting from dust mixing with finer local aerosol fractions. Peculiarities and patterns of the aerosol dynamics at different stages of dust-loading event are revealed and discussed.

    This study investigated the attitudes and beliefs of pig farmers and hunters in Germany, Bulgaria and the western part of the Russian Federation towards reporting suspected cases of African swine fever (ASF). Data were collected using a web-based questionnaire survey targeting pig farmers and hunters in these three study areas. Separate multivariable logistic regression models identified key variables associated with each of the three binary outcome variables whether or not farmers would immediately report suspected cases of ASF, whether or not hunters would submit samples from hunted wild boar for diagnostic testing and whether or not hunters would report wild boar carcasses. The results showed that farmers who would not immediately report suspected cases of ASF are more likely to believe that their reputation in the local community would be adversely affected if they were to report it, that they can control the outbreak themselves without the involvement of veterinary services and that laboratory confirmation would take too long. The modelling also indicated that hunters who did not usually submit samples of their harvested wild boar for ASF diagnosis, and hunters who did not report wild boar carcasses are more likely to justify their behaviour through a lack of awareness of the possibility of reporting. These findings emphasize the need to develop more effective communication strategies targeted at pig farmers and hunters about the disease, its epidemiology, consequences and control methods, to increase the likelihood of early reporting, especially in the Russian Federation where the virus circulates.

    The purpose of this research work is to present data that show the seasonal changes (spring-summer-autumn) of basic erythrocyte-metric parameters (ЕL: Erythrocyte length, ЕW: Erythrocyte width, ЕL/ЕW, ES: Erythrocyte size; NL: Nucleus length, NW: Nucleus width, NL/NW; NS: Nucleus size, NS/ES: Nucleus-cytoplasmic ratio) in Pelophylax ridibundus populations from three biotopes located on two rivers in Southern Bulgaria (less disrupted biotope, with domestic sewage pollution and heavy metal pollution). Differences of high statistical significance were found among the different populations. Within the population living in conditions of domestic sewage pollution, for the entire period of the investigation the erythrocytes and their nuclei had an elliptical shape (a slight elongation of ellipses in autumn) and the biggest sizes (EL, EW, ES, NL and NS were constantly higher than the less disrupted biotope), NS/ES, became significantly smaller in autumn. Throughout the period of investigation, the values of all nine cellular and nuclear parameters were statistically-significantly the lowest in the population from the biotope with heavy metal pollution. The parameters: EL, ЕW, NL, NW and ES became significantly lower, progressively and statistically, during seasonal transitions. Cells and nuclei grew ovular in shape in comparison to the populations from the other two biotopes (this process was most pronounced in autumn) and NS/ES numbers were significantly decreased in summer and autumn.

    The coast of the Bulgarian Black Sea is a popular summer holiday destination. The Dam of Iskar is the largest artificial dam in Bulgaria, with a capacity of 675 million m3. It is the main source of tap water for the capital Sofia and for irrigating the surrounding valley. There is a close relationship between the quality of aquatic ecosystems and human health as many infections are waterborne. 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. PMID:26133133

    In 2009, INFREP, a network of VLF (20-60 kHz) and LF (150-300 kHz) radio receivers, was put into operation in Europe having as principal goal, the study of disturbances produced by the earthquakes on the propagation properties of these signals. On May 22nd, 2012 an earthquake with Mw=567 occurred in Bulgaria, near Sofia, inside the "sensitive" area of the INFREP VLF/LF electromagnetic network. The data collected on different frequencies, during April-May 2012 were studied using different methods of analysis: daily correlation methods, spectral approaches and terminator time techniques, in order to find out possible connections between the seismic activity and the subionospheric propagation properties of radio waves. The studies were performed with the help of a specially designed LabVIEW application, which accesses the VLF/LF receiver through internet. This program opens the receiver's web-page and automatically retrieves the list of data files to synchronize the user-side data with the receiver's data. Missing zipped files are also automatically downloaded. The application performs primary, statistical correlation and spectral analysis, appends daily files into monthly and annual files and performs 3D colour-coded maps with graphic representations of VLF and LF signals' intensities versus the minute-of-the-day and the day-of-the-month, facilitating a near real-time observation of VLF and LF electromagnetic waves' propagation. Another feature of the software is the correlation of the daily recorded files for the studied frequencies by overlaying the 24 hours radio activity and taking into account the sunrise and sunset. Data are individually processed (spectral power, correlations, differentiation, filtered using bandpass, lowpass, highpass). JTFA spectrograms (Cone-Shaped Distribution CSD, Gabor, Wavelet, short-time Fourier transform STFT, Wigner-Ville Distribution WVD, Choi-Williams Distribution CWD) are used, too.

    The relationship between intensity parameters, such as the corrected anisotropy degree P‧ and mean susceptibility Km for plutons with similar magnetic mineralogy, yields a criterion to determine the origin of their magnetic fabric: for a same mineralogy, the higher the P‧ values for the same mean susceptibility Km (irrespective of its absolute value) the higher tectonic effect was possible. Using this criterion, comparison of the magnetic fabric of the Upper Cretaceous mid- to shallow crustal level Plana pluton with that of other small Upper Cretaceous plutonic bodies in Sredna Gora Zone (Central and Southeast Bulgaria) highlights the structural evolution of the Plana pluton. The central part of Plana pluton and its southwest, west and east margins have preserved their emplacement fabric. Along its northern contact the pluton is affected by the last movements within the Okol Shear Zone where high-temperature S/L mylonites developed. The fabric of the pluton at its southeastern border was disturbed during the intrusion of the neighboring Gutsal pluton. The similarity in the orientation of magmatic and magnetic structures preserved in the central and southern parts of the Plana pluton and the transition from magmatic to high-temperature superimposed foliations and lineations at its north contact point to a composite superimposed shear-induced and emplacement-related magmatic magnetic fabric. Nearly vertical orientation of magnetic and magmatic foliations and lineations from the undeformed parts of the pluton shows a process of vertical magma rising and emplacement. The sub-vertical high-temperature solid-state mylonitic foliation and dip-parallel stretching lineation in the pluton along its northern contact reveals the transpression nature of the deformation in the vicinity of Okol Shear Zone with a strong pure shear component. The smooth transition between the deformed and undeformed parts of Plana pluton reveals the syn-kinematic character of the emplacement.

    The study presented here is one of the very first aimed at exploring the potential spread of classical swine fever (CSF) from backyard pigs to other domestic pigs. Specifically, we used a spatial stochastic spread model, called Be-FAST, to evaluate the potential spread of CSF virus (CSFV) in Bulgaria, which holds a large number of backyards (96% of the total number of pig farms) and is one of the very few countries for which backyard pigs and farm counts are available. The model revealed that, despite backyard pigs being very likely to become infected, infections from backyard pigs to other domestic pigs were rare. In general, the magnitude and duration of the CSF simulated epidemics were small, with a median [95% PI] number of infected farms per epidemic of 1 [1,4] and a median [95% PI] duration of the epidemic of 44 [17,101] days. CSFV transmission occurs primarily (81.16%) due to indirect contacts (i.e. vehicles, people and local spread) whereas detection of infected premises was mainly (69%) associated with the observation of clinical signs on farm rather than with implementation of tracing or zoning. Methods and results of this study may support the implementation of risk-based strategies more cost-effectively to prevent, control and, ultimately, eradicate CSF from Bulgaria. The model may also be easily adapted to other countries in which the backyard system is predominant. It can also be used to simulate other similar diseases such as African swine fever.

    Continental denudation is the mass transfer of rock from source areas to sedimentary depocentres, and is typically the result of Earth surface processes. However, a process known as tectonic denudation is also understood to expose deep-seated rocks in short periods of geological time by displacing large masses of continental crust along shallow-angle faults, and without requiring major contributions from surface erosion. Some parts of the world, such as the Basin and Range in the USA or the Aegean province in Europe, have been showcased for their Cenozoic tectonic denudation features, commonly described as metamorphic core-complexes or as supradetachment faults. Based on 22 new apatite fission-track (AFT) and 21 helium (AHe) cooling ages among rock samples collected widely from plateau summits and their adjacent valley floors, and elaborating on inconsistencies between the regional stratigraphic, topographic and denudational records, this study frames a revised perspective on the prevailing tectonic denudation narrative for southern Bulgaria. We conclude that conspicuous landforms in this region, such as erosion surfaces on basement-cored mountain ranges, are not primarily the result of Paleogene to Neogene core-complex formation. They result instead from "ordinary" erosion-driven, subaerial denudation. Rock cooling, each time suggesting at least 2 km of crustal denudation, has exposed shallow Paleogene granitic plutons and documents a 3-stage wave of erosional denudation which progressed from north to south during the Middle Eocene, Oligocene, Early to Middle Miocene, and Late Miocene. Denudation initially prevailed during the Paleogene under a syn-orogenic compressional regime involving piggyback extensional basins (Phase 1), but subsequently migrated southward in response to post-orogenic upper-plate extension driven by trench rollback of the Hellenic subduction slab (Phase 2). Rare insight given by the denudation pattern indicates that trench rollback

    The Chelopech deposit is one of the largest European gold deposits and is located 60 km east of Sofia, within the northern part of the Panagyurishte mineral district. It lies within the Banat-Srednegorie metallogenic belt, which extends from Romania through Serbia to Bulgaria. The magmatic rocks define a typical calc-alkaline suite. The magmatic rocks surrounding the Chelopech deposit have been affected by propylitic, quartz-sericite, and advanced argillic alteration, but the igneous textures have been preserved. Alteration processes have resulted in leaching of Na2O, CaO, P2O5, and Sr and enrichment in K2O and Rb. Trace element variation diagrams are typical of subduction-related volcanism, with negative anomalies in high field strength elements (HFSE) and light element, lithophile elements. HFSE and rare earth elements were relatively immobile during the hydrothermal alteration related to ore formation. Based on immobile element classification diagrams, the magmatic rocks are andesitic to dacitic in compositions. Single zircon grains, from three different magmatic rocks spanning the time of the Chelopech magmatism, were dated by high-precision U-Pb geochronology. Zircons of an altered andesitic body, which has been thrust over the deposit, yield a concordant 206Pb/238U age of 92.21 ± 0.21 Ma. This age is interpreted as the crystallization age and the maximum age for magmatism at Chelopech. Zircon analyses of a dacitic dome-like body, which crops out to the north of the Chelopech deposit, give a mean 206Pb/238U age of 91.95 ± 0.28 Ma. Zircons of the andesitic hypabyssal body hosting the high-sulfidation mineralization and overprinted by hydrothermal alteration give a concordant 206Pb/238U age of 91.45 ± 0.15 Ma. This age is interpreted as the intrusion age of the andesite and as the maximum age of the Chelopech epithermal high-sulfidation deposit. 176Hf/177Hf isotope ratios of zircons from the Chelopech magmatic rocks, together with published data on the

    In the southeastern Rhodope, both in southern Bulgaria and northern Greece, Mesozoic low-grade to non-metamorphic units, together with similar units in the eastern Vardar zone, were designated as the Circum-Rhodope Belt (CRB) that fringes the Rhodope high-grade metamorphic complex. In the Bulgarian southeastern Rhodope, Mesozoic units show a complicated tectono-stratigraphy underlaid by amphibolite-facies basement units. The basement sequence includes a lower orthogneiss unit with eclogite and meta-ophiolite lenses overlain by an upper marble-schist unit, presumably along a SSW-directed detachment fault as indicated by shear sense indicators. The Mesozoic sequence starts with greenschist units at the base, overlaying the basement along the tectonic contact. Mineral assemblages such as actinolite-chlorite-white mica ± garnet in schists and phyllites indicate medium greenschist facies metamorphism. Kinematic indicators in the same unit demonstrate a top-to-the NNW and NNE shear deformation coeval with metamorphism, subparallel to NW-SE to NE-SW trending mineral elongation lineation and axis of NW vergent small-scale folds. The greenschist unit is overlain by tectonic or depositional contact of melange-like unit that consists of diabases with Lower Jurassic radiolarian chert interlayers, Upper Permian siliciclastics and Middle-Upper Triassic limestones found as blocks in olistostromic member, embedded in Jurassic-Lower Cretaceous turbiditic matrix. The uppermost sedimentary-volcanogenic unit is represented by andesito-basalt lavas and gabbro-diorites, interbedded with terrigeneous-marl and tufaceous sediments that yield Upper Cretaceous (Campanian) fossils, related to the Late Cretaceous back-arc magmatic activity to the north in Sredna Gora zone. Petrologic and geochemical data indicates sub-alkaline and tholeiitic character of the greenschists and ophiolitic basaltic lavas, and the latter are classified as low-K and very low-Ti basalts with some boninitic affinity

    Eastern Srednogorie in Bulgaria is the widest segment of an extensive magmatic arc that formed by convergence of Africa and Europe during Mesozoic to Tertiary times. Northward subduction of the Tethys Ocean beneath Europe in the Late Cretaceous gave rise to a broad range of basaltic to more evolved magmas with locally associated Cu-Au mineralization along this arc. We used U-Pb geochronology of single zircons to constrain the temporal evolution of the Upper Cretaceous magmatism and the age of basement rocks through which the magmas were emplaced in this arc segment. High precision isotope dilution-thermal ionization mass spectrometry (ID-TIMS) was combined with laser ablation-inductively coupled plasma mass spectrometry (LA-ICPMS) for spatial resolution within single zircon grains. Three tectono-magmatic regions are distinguished from north to south within Eastern Srednogorie: East Balkan, Yambol-Burgas and Strandzha. Late Cretaceous magmatic activity started at ~ 92 Ma in the northernmost East Balkan region, based on stratigraphic evidence and limited geochronology, with the emplacement of minor shallow intrusions and volcanic rocks onto pre-Cretaceous basement. In the southernmost Strandzha region, magmatism was initiated at ~ 86 Ma with emplacement of gabbroic to dioritic intrusions and related dikes into metamorphic basement rocks that have previously been overprinted by Jurassic-Lower Cretaceous metamorphism. The Yambol-Burgas region is an extensional basin between the East Balkan and the Strandzha regions, which broadens and deepens toward the Black Sea further east and is filled with a thick pile of marine sediments and submarine extrusive volcanic rocks accompanied by coeval intrusions. This dominantly mafic magmatism in the intermediate Yambol-Burgas region commenced at ~ 81 Ma and produced large volumes of potassium-rich magma until ~ 78 Ma. These shoshonitic to ultrapotassic basaltic to intermediate magmas formed by differentiation of ankaramitic (high

  7. Late Precambrian Balkan-Carpathian ophiolite — a slice of the Pan-African ocean crust?: geochemical and tectonic insights from the Tcherni Vrah and Deli Jovan massifs, Bulgaria and Serbia

    The Balkan-Carpathian ophiolite (BCO), which outcrops in Bulgaria, Serbia and Romania, is a Late Precambrian (563 Ma) mafic/ultramafic complex unique in that it has not been strongly deformed or metamorphosed, as have most other basement sequences in Alpine Europe. Samples collected for study from the Tcherni Vrah and Deli Jovan segments of BCO include cumulate dunites, troctolites, wehrlites and plagioclase wehrlites; olivine and amphibole-bearing gabbros; anorthosites; diabases and microgabbros; and basalts representing massive flows, dikes, and pillow lavas, as well as hyaloclastites and umbers (preserved sedimentary cover). Relict Ol, Cpx and Hbl in cumulate peridotites indicate original orthocumulate textures. Plagioclase in troctolites and anorthosites range from An 60 to An 70. Cumulate gabbro textures range from ophitic to poikilitic, with an inferred crystallization order of Ol-(Plag+Cpx)-Hbl. The extrusive rocks exhibit poikilitic, ophitic and intersertal textures, with Cpx and/or Plag (Oligoclase-Andesine) phenocrysts. The major opaques are Ti-Magnetite and Ilmenite. The metamorphic paragenesis in the mafic samples is Chl-Trem-Ep, whereas the ultramafic rocks show variable degrees of serpentinization, with lizardite and antigorite as dominant phases. Our samples are compositionally and geochemically similar to modern oceanic crust. Major element, trace element and rare earth element (REE) signatures in BCO basalts are comparable to those of MORB. In terms of basalt and dike composition, the BCO is a 'high-Ti' or 'oceanic' ophiolite, based on the classification scheme of Serri [Earth Planet. Sci. Lett. 52 (1981) 203]. Our petrologic and geochemical results, combined with the tectonic position of the BCO massifs (overlain by and in contact with Late Cambrian island arc and back-arc sequences), suggest that the BCO may have formed in a mid-ocean ridge setting. If the BCO records the existence of a Precambrian ocean basin, then there may be a relationship

    2003-09-01

    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.

    2012-04-01

    The article discusses the periods of environmental education (EE) development in connection with internal social and global international influences, mainly the effect of the First United Nations Conference on Human environment in Stockholm 1972, the 1992 Earth Summit in Rio de Janeiro and the 2002 Earth Summit in Johannesburg. It pays attention to the impact of the social background and the role of science and pedalogical research on the different stages in the curricular and textbooks development. The school subjects' contents and educational technologies also evolved towards student-centered interactive education in school and out of school. A system of EE from nursery to postgraduate and lifelong education was developed in 1984 and a great part of it has been introduced in the different educational stages since then. After 1989 more than 132 NGOs and communities on ecology and environmental education were established and many others incorporated environmental education aspects in their activities. Still there are many unsolved problems in EE.

    The paper reveals the changing pattern of Bulgarian Radiotherapy (RT) care after the successful implementation of 15 projects for 100 million euro under the European Regional Development Fund in Operational Programme for Regional Development 2007-2013. The project enables a total one-step modernization of 14 Bulgarian RT Centres and creation of a new one. At the end of the Programme (mid 2015), 16 new Linacs and 2 modern cobalt machines will be available together with 11 virtual CT simulators, 5 CT simulators, 1 MRI and 1 PET CT for RT planning and all dosimetry facilities needed. Such a modernization has moved Bulgarian RT forward, with 2.7 MV units per one million of population (MV/mln.inh) in comparison with 0.9 MV/mln.inh in 2012. Guild of Bulgarian Radiotherapists includes 70 doctors, 46 physicists and 10 engineers, together with 118 RTTs and 114 nurses and they all have treated 16,447 patients in 2013. Major problems are inadequate reimbursement from the monopolistic Health Insurance Fund (900 euro for 3D conformal RT and 1500 euro for IMRT); fragmentation of RT care with 1-2 MV units per Centre; no payment for patient travel expenses; need for quick and profound education of 26% of doctors and 46% of physicists without RT license, along with continuous education for all others; and resource for 5000-9000 more patients to be treated yearly by RT in order to reach 45-50% from current service of 32%. After 15 years of struggle of RT experts, finally the pattern of Bulgarian RT care at 2014-2015 is approaching the level of modern European RT.

    Bryophyte species composition and 26 common physico-chemical and inorganic chemical parameters were assessed at 23 selected sites in the Maritsa River (BG) over a 4-year period. Principal components analyses (PCA) of both bryophytes and water variables distinguished different locations in the ecosystem. The data imply that the content of elements measured in bryophytes represents river contamination, while species compositional patterns reflect hydromorphology and general degradation. This study for the first time combined aquatic bryophyte occurrence, the bioaccumulation of 17 macro-and microelements in 17 species, and 26 water factors by principal components analysis (PCA) in an assessment of river pollution.

    Studies were carried out on the species composition of helminths as found in does in individual region of the Rhodope and Balkan Mountains and in the northeast part of this country. A total of 28 helminth species were found, belonging to 8 families as follows: class Trematoda--one family with one species; class Cestoda--one family with one species; and class Nematoda--6 families with 26 species. Most widespread were the species Chabertia ovina, with 82 per cent of infected animals; Spiculopteragia spiculoptera, with 74.1 per cent of infected animals; Ostertagia leptospicularis, with 66.6 per cent of infected animals; and Ostertagia asymetrica and Muflonagia podjapolskyi, with 33.3 per cent of infected animals. The necropsy of a doe, found in the region of the central Rhodope Mountains in a state of strongly manifested cachexia, revealed a massive Chabertia ovina infection. The severe traumatic and toxic inflammation of the intestines as caused by the parasite was characterized by oedema of the mucous membrane, with hyperaemia and pin-point hemorrhages. Similar Chabertia ovina infections were also found in does of other regions.

    Danube river which flows into the Black Sea is one of the world's biggest amount sediment transporter to the marine environment. Throughout long geological periods, Danube has formed many channel structures and the channel developments are still being continuened. Danube River has caused a lot of potential gas hydrate formations which spread over quite larger areas. Under the frame of SUGAR Project, high resolution multichannel seismic data were collected using the facilities of Seismic Laboratory (SeisLab) in the Institute of Marine Sciences and Technology of Dokuz Eylül University on board R/V Maria S. Merian in 2013. More then 2300 km Multichannel seismic reflection data acquired across the palaeo Danube delta to investigate BSR and potential gas hyrdate areas on the continental shelf where Danube river reaches to the Black Sea, BSR areas and potential gas hyrdates. Also, in relation with high sediment input, the effects of deltas on BSR's are aimed to research and several of inactive and partly buried channel systems could be mapped. There are large number of buried channel levee systems which seem to underlain by a continuous BSR indicating availability of free gas. There are also a significant reflector of inverted polarity was identified within a depth of about 100 m below seafloor. A very prominent BSR with reversed polarity is determined 200 ms TWT below seafloor on the eastern levee of the channel and simulate and crosscut the sediment layer. Three distinct BSRs as multiple BSR signature are observed on the high resolution multichannel seismic with a slightly varying dips. Multiple BSR's up to 5 BSRs are exist around river channels and paleochannels which have formed during different geological periods. In some paleochannel areas, high amount of sediment transportation causes dissolution of gashyrdate structures. At such areas seismic signals are being absorbed and structures which indicate dissolved gas are determined. In addition parasound data show dense amount of gas flares with acoustic blanking in about 30 m depth below seafloor at the BSR outcrop.

  3. Kinematics of Tertiary convergence and extension at the western margin of the Rhodopes (SW Bulgaria)

    Integrating the results of recent structural geological fieldwork with age constraints reported in the literature we propose a kinematic model for Eocene to Miocene tectonics in the western Rhodopes. In the past years, several authors have claimed that low-angle normal faults in the western Rhodopes and adjacent external Hellenides formed in the framework of beginning Aegean extension. The oldest low-angle normal faults identified so far were active since the Middle or Late Eocene, among them the Vertiskos-Kerdilion (Brun & Sokoutis 2007) and Ribnovo faults (Burchfiel et al. 2003) which separate "Rhodopean" rock units (Sidironero-Mesta and Asenica units) characterized by Jurassic protolith ages of orthogneiss in the footwall from "Serbomacedonian" units (Vertiskos-Ogražden unit) with significantly older orthogneiss protolith ages in the hanging wall. Activity of these extensional faults temporally overlaps with that of the Nestos shear zone. The Nestos shear zone was probably active during the entire Eocene (Jahn-Awe et al. in press) and accommodated thrusting of the Sidironero-Mesta unit onto the Pangaion-Pirin unit which we interpret to be derived from the Apulian plate (see also Dinter 1998). The fault geometries observed in the field suggest that the Ribnovo fault soles into the Nestos faults forming a large scale Late Eocene extensional fault system (Mesta-Kerdilion detachment system) with a consistent top-to-the-SW displacement sense. This implies that in the Middle or Late Eocene the Nestos shear zone changed its kinematics from reverse to normal faulting. After the first period of extensional faulting, the Mesta-Kerdilion detachment system was offset by a series of steeply NE-dipping normal faults in the NE slopes of the Pirin mountains. Following a tectonically quiet period in the Late Oligocene and Early Miocene, the Strimon valley detachment became active in the Middle Miocene. It obliquely cuts through the Mesta-Kerdilion detachment system resulting in the offset between the Vertiskos-Kerdilion and Ribnovo faults which probably originally were one coherent fault. Although the shear sense of the Strimon valley detachment is also top-to-the-SW, it was thus kinematically indepent of the Mesta-Kerdilion detachment system. Since the horizontal displacement amount of the Strimon valley detachment increases from N to S, we assume that the Strimon valley detachment accommodated relative rotation between the Rhodopes and Hellenides starting in the Middle Miocene (Kissel & Laj 1988) that resulted in particularly strong extension within the Aegean and corresponds to the the evolution of the curvature of the Aegean arc.

    Detrital heavy mineral and bulk rock geochemistry and a review of sandstone petrographic data have been used to investigate the post-collisional effusive magmatism that followed the closure of the Vardar Ocean and the generation of volcanic sediments in a complex and compositionally variable volcanic region. Available petrographic data gives evidence of contributions from three key source areas corresponding to the three main tectonic units: the structurally lower Gneiss-Migmatite Complex (Byala Reka-Kechros and Kesebir-Kardamos domes) and the upper Variegated (Kimi) Complex, both fringed by the low-to-medium-grade Mesozoic rocks of the Circum-Rhodope Belt. Besides the deposition of siliciclastic material, volcanic contributions from both, intermediate and acid products represent an important source of sediment in the area. Despite dominant intermediate to acid volcanic products, volcanic lithic fragments in sandstones (microlithic, lathwork and brown vitric textures) indicate main inputs from intermediate and basic-intermediate products generating questions on the interpretation of volcanic detritus in reconstruction of provenance. Detrital amphibole and pyroxene chemistry is used to characterise the supply of volcanic material as well as the dispersal mechanisms and understand the role played by each of the volcanic centers present in the area in the infill of the north-western Thrace basin. Amphibole chemistry reveals high compositional heterogeneity according to both compositional variability of the numerous volcanic centres active at the time of deposition and presence of metamorphic amphibole. 4Al and AlT apfu values indicate that most of the amphiboles from the NERZ are not of volcanic origin and their presence can only be attributed to the numerous amphibolite facies metamorphic rocks abundantly documented in the area. Detrital amphibole compositions from the ZKVS indicate major contributions from the Iran Tepe and Zvedzel volcanoes. Analysed detrital clinopyroxenes from the NERZ are mostly diopside-augite, with no hedenbergite or Fe-augite detected. The 4Al/6Al ratio is comparable with compositions of volcanic pyroxenes from the Momchilgrad-Arda (ZKVS) region and products from the pre-caldera phase of the Borovitza.

    Recent studies on archaeal diversity in few salterns have revealed heterogeneity between sites and unique structures of separate places that hinder drawing of generalized conclusions. Investigations on the archaeal community composition in P18, the biggest crystallizer pond in Pomorie salterns (PS) (34% salinity), demonstrated unusually high number of presented taxa in hypersaline environment. Archaeal clones were grouped in 26 different operational taxonomic units (OTUs) assigned to 15 different genera from two orders, Halobacteriales and Haloferacales. All retrieved sequences were related to culturable halophiles or unculturable clones from saline (mostly hypersaline) niches. New sequences represented 53.9% of archaeal OTUs. Some of them formed separate branches with 90% similarity to the closest neighbor. Present results significantly differed from the previous investigations in regard to the number of presented genera, the domination of some genera not reported before in such extreme niche, and the identification of previously undiscovered 16S rRNA sequences.

    Establishing topsoil magnetic database at a national scale provides important information for soil classification, evaluation of soil drainage, indirect estimation of the total soil carbon and initial planning in precision agriculture. The Bulgarian database consists of 511 topsoil samples from the upper 20 cm of natural unpolluted soils. Samples 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 show specific peculiarities and dependence from various parameters. Statistical factor analysis revealed that 87% from the total variance can be explained by four factors. The main factor is dominated by the contribution from concentration-dependent magnetic parameters, second one reflects the role of fine-grained pedogenic magnetic fraction, the third one is determined by the properties of the parent material, fourth one is governed by 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 results emphasize the major role of geology (parent material) for the magnetic signature of topsoil samples on a national scale using sampling density of 1 sample/200 km2. Spatial interpolation of different magnetic parameters using modelled experimental variograms and kriging algorithm highlight lateral peculiarities in the concentration and grain size of the strongly magnetic iron oxides in the topsoils. Additional geochemical data for selected set of samples and meteorological information reveal the role of climate characteristics (mean annual temperature and precipitation) on the formation and development of the strongly magnetic pedogenic fraction in soils developed on the same parent material.

    Gastric cancer is the fourth most common cancer worldwide with one million new casesyearly and the second most frequent cause of cancer death. Although surgery is the leading treatment modality of gastric cancer the survival remains low (5- year survival is reported to be 25% in Europe and 60% in the Eastern world). The risk of locoregional recurrence grows with the increase of the tumor stage. In order to improve locoregional control a number of clinical studies in the last four decades have examined different strategies of adjuvant therapy, including chemotherapy, radiotherapy, chemoradiation with ambiguous results. Various regimens of radiotherapy alone, applied preand postoperatively or in combination with chemotherapy in pre- and postoperative settings have been studied. With the present article, the authors present the world experience of radiotherapy application in gastric carcinoma, supporting its introduction in to Bulgarian clinical practice. The study results concerning this topic have been discussed. SWOG/Intergroup 0116 study showed that postoperative chemoradiation leads to increased 5-year overall survival compared with surgery alone. A recent metaanalysis on randomized trials in operable gastric cancer, found that adjuvant radiotherapy leads to 20 % improvement in disease free survival and overall survival and found no subgroup of patients who do not benefit from adjuvant radiotherapy. The available data from the published studies and metaanalysis completely supports the introduction of chemoradiation for gastric cancer and in Bulgarian radiotherapy practice with the opportunity of gaining own experience.

  19. Underground coal gasification with integrated carbon dioxide mitigation supports Bulgaria's low carbon energy supply

    2013-04-01

    Underground coal gasification allows for the utilisation of coal reserves that are economically not exploitable due to complex geological boundary conditions. The present study investigates underground coal gasification as a potential economic approach for conversion of deep-seated coals into a high-calorific synthesis gas to support the Bulgarian energy system. Coupling of underground coal gasification providing synthesis gas to fuel a combined cycle gas turbine with carbon capture and storage is considered to provide substantial benefits in supporting the Bulgarian energy system with a competitive source of energy. In addition, underground voids originating from coal consumption increase the potential for geological storage of carbon dioxide resulting from the coupled process of energy production. Cost-effectiveness, energy consumption and carbon dioxide emissions of this coupled process are investigated by application of a techno-economic model specifically developed for that purpose. Capital (CAPEX) and operational expenditure (OPEX) are derived from calculations using six dynamic sub-models describing the entire coupled process and aiming at determination of the levelised costs of electricity generation (COE). The techno-economic model is embedded into an energy system-modelling framework to determine the potential integration of the introduced low carbon energy production technology into the Bulgarian energy system and its competitiveness at the energy market. For that purpose, boundary conditions resulting from geological settings as well as those determined by the Bulgarian energy system and its foreseeable future development have to be considered in the energy system-modelling framework. These tasks comprise integration of the present infrastructure of the Bulgarian energy production and transport system. Hereby, the knowledge on the existing power plant stock and its scheduled future development are of uttermost importance, since only phasing-out power plants can be economically substituted by low carbon based technologies. Furthermore, the integrated annual load management notably contributes to innovative process integration becoming economic in an energy system affected by low efficiency and flexibility. Further limiting flexibility, the geographic location of this innovative low carbon energy production technology strictly depends on geological boundary conditions, namely the presence of exploitable coal resources, and availability of energy transport networks to supply potential end users with the product. Hereby, feeding upgraded synthesis gas directly into the Bulgarian gas pipeline network avoiding its conversion into electricity is an alternative approach with relevant economic potentials. For that purpose, the proximity and availability of these transport networks as well as the demand of end users are validated by the integrated energy system model. Coupling our techno-economic process model to an energy system-modelling framework allows the determination of the future economical potentials and the limitations for the implementation of a low carbon energy production technology into the Bulgarian energy system. The obtained results show that the Bulgarian energy system can significantly benefit from the integration of underground coal gasification considering carbon dioxide mitigation technologies potentially initiating a continuous substitution of imported fuels by domestic coal resources.

    A partir des données normalisées des assurances grêle, on mesure l'efficacité de la lutte contre la grêle de deux expériences différentes en employant un test bivariable habituellement utilisé pour détecter une dérive dans des séries chronologiques pluviométriques. La première expérience est le programme opérationnel bulgare qui met en oeuvre la méthode soviétique d'ensemencement par fusées dans huit régions, appelées polygones, du nord-ouest et du sud de la Bulgarie; l'autre expérience est le programme français développé par l'Association Nationale d'Etude et de Lutte contre les Fléaux Atmosphériques (ANELFA) qui utilise des générateurs au sol de noyaux d'iodure d'argent fonctionnant avant et pendant le développement des orages à grêle. Les données utilisées pour le test sont les pourcentages annuels de pertes aux récoltes dans les zones cibles et contrôles avant et pendant les années d'ensemencement. Lorsqu'un changement de tendance est décelé dans la cible en comparaison de la zone de contrôle, le test bivariable indique la date du changement, son niveau de signification statistique ainsi que son taux. Pour chacun des deux programmes, on trouve une diminution significative des dommages par la grêle dans les zone ensemencées, et la période de cette diminution correspond au développement des activités de suppression de la grêle dans les deux pays.

    Data in the literature addressing the ability of Toxocara infection in humans to induce development of atopic disease are controversial. Aim of our study was to determine the seroprevalence of anti-Toxocara antibodies in three groups of people: subjects with allergic symptoms and presence of allergen-specific IgE, subjects with allergic symptoms and absence of allergen-specific IgE, and clinically healthy blood donors. Serum samples from all subjects were tested by ELISA and Western blot for presence of specific antibodies against Toxocara canis. The results of our study did not support the link between toxocariasis and allergic manifestations in atopic patients. Among subjects with allergic symptoms and absence of atopy was found seroprevalence of 2.2% in Western blot. Same index in patients with atopy was 0.8%, and in clinically healthy blood donors 4.0%. Our study gives us grounds to consider that it is appropriate persons with allergic reactions, without evidence of atopy to be tested for presence of anti - Toxocara antibodies in the course of their diagnostic evaluation. Data from clinically healthy persons suggest that there is a "hidden" infection among the population, which is not clinically manifested. This article is protected by copyright. All rights reserved.

    A study of the natural growth rate of the population using female cohorts by birth year has been carried out for the first time in our country. The study comprises 14 cohorts. The following characteristics are recorded: birth year, social group, educational level, number of live births, age of marriage, infant mortality rate, proto- and intergenetic intervals. Our report presents the key indicators of natural growth of population in the studied cohorts. A consistent trend of decreasing the number of livebirths is established. In the first studied cohort (1895-1899) the average number of offspring per woman is 3.94, reaching a level of 1.77 in the 1960-1964 cohort. The indicators for natural growth of population exhibit a similar trend. The summary fertility rate in the reference period decreases with more than 2 points--from 4.47 in 1895-1899 to 1.73 in 1960-1964. Likewise, the total reproduction rate goes down from 2.54 to 0.78 for the same period. Considerable changes have occurred in the indicators total period fertility rate and marriage fertility rate of women. For a period of 110 years the former has decreased 3.5 times, the latter--8 times. The drastic drop of the indicators of natural growth of the population is accounted for by an intricate complex of social, economic, psychological and biological factors. The marked aging of the population and the decrease of the percentage of women in active fertility age play a certain role in this process. The ascertained changes in the reproductive behavior and age structure of the female population are factors intensifying the unfavorable trends in the natural growth rate of the population in our country.

    Sixteen sampling sites along the stream of Kamchia River were considered as environmental objects in the multivariate statistical study aimed to identify and apportion patterns of sampling sites, latent factors responsible for the data structure and their relation to the emitter industrial and anthropogenic sources in the vicinity of the sampling sites. As variables 11 surface water parameters monitored for a long time period (up to 11 years) were used. Four main site patterns were revealed by cluster analysis (urban, rural, near-to dam and estuary) and for each site latent factors were identified and apportioned (among them "metallurgical", "food production", "winery", domestic wastes", "natural"). The relative contribution of each identified pollution source to the formation of the total concentration of each chemical species or physicochemical parameter was determined and compared to the real emitters in the region of interest.

    The generalizability of the psychopathy construct to Eastern European cultures has not been well-studied, and no prior studies have evaluated psychopathy in non-offender samples from this population. The current validation study examines the factor structure, internal consistency, and external validity of the Bulgarian translation of the Hare Psychopathy Checklist: Screening Version. Two hundred sixty-two Bulgarian adults from the general community were assessed, of which 185 had a history of substance dependence. Confirmatory factor analysis indicated good fit for the two-, three-, and four-factor models of psychopathy. Zero-order and partial correlation analyses were conducted between the two factors of psychopathy and criterion measures of antisocial behavior, internalizing and externalizing psychopathology, personality traits, addictive disorders and demographic characteristics. Relationships to external variables provided evidence for the convergent and discriminant validity of the psychopathy construct in a Bulgarian community sample. PMID:25313268

    Copper ore mining and processing are among the most harmful anthropogenic influences for the environment and they are a subject of international and national law regulations. Recultivation of areas influenced by mining and processing industry is commonly applied and monitored in order to restore as much as possible the natural environment. In this study, environmental magnetic methods are applied in order to assess the degree of soil restoration in terms of soil development, after remediation of waste dump from Cu-processing plant. Soils developed under birch forest stands of different age (5, 15, and 25 years) as well as raw waste material were sampled along depth down to 20-30 cm. Variations in magnetic parameters and ratios obtained (magnetic susceptibility, frequency-dependent magnetic susceptibility, anhysteretic remanence (ARM), isothermal remanence (IRM), ARM/IRM100mT) suggest the presence of magnetic enhancement in the upper 0-15 cm, the thickness of this layer varying depending on the age of the forest stand. Magnetic mineral responsible for this enhancement is of magnetite type, while waste material contains a large amount of hematite, as evidenced by coercivity analysis of IRM acquisition curves and thermal demagnetization of composite IRM. Magnetic grain-sized proxy parameters suggest that magnetite particles are coarser, magnetically stable, while no or minor amount of superparamagnetic grains were detected at room temperature. A well-defined linear regression between the topsoil magnetic susceptibility and the approximate age of the forest stand provides an indication that the magnetic enhancement is of pedogenic origin. It is concluded that the observed magnetic enhancement of recultivated soils studied is linked to a combined effect of pedogenic contribution and possible additions of industrial ashes as a liming agent for soil restoration.

    Uranium mining and milling activities adversely affect the microbial populations of impacted sites. The negative effects of uranium on soil bacteria and fungi are well studied, but little is known about the effects of radionuclides and heavy metals on archaea. The composition and diversity of archaeal communities inhabiting the waste pile of the Sliven uranium mine and the soil of the Buhovo uranium mine were investigated using 16S rRNA gene retrieval. A total of 355 archaeal clones were selected, and their 16S rDNA inserts were analysed by restriction fragment length polymorphism (RFLP) discriminating 14 different RFLP types. All evaluated archaeal 16S rRNA gene sequences belong to the 1.1b/Nitrososphaera cluster of Crenarchaeota. The composition of the archaeal community is distinct for each site of interest and dependent on environmental characteristics, including pollution levels. Since the members of 1.1b/Nitrososphaera cluster have been implicated in the nitrogen cycle, the archaeal communities from these sites were probed for the presence of the ammonia monooxygenase gene (amoA). Our data indicate that amoA gene sequences are distributed in a similar manner as in Crenarchaeota, suggesting that archaeal nitrification processes in uranium mining-impacted locations are under the control of the same key factors controlling archaeal diversity.

    2015-10-01

    The depositional environments and hydrocarbon potential of the siliciclastic, clayey and carbonate sediments from the Middle Miocene succession in the Varna-Balchik Depression, located in the south-eastern parts of the Moesian Platform, were studied using core and outcrop samples. Based on the lithology and resistivity log the succession is subdivided from base to top into five units. Siliciclastic sedimentation prevailed in the lower parts of units I and II, whereas their upper parts are dominated by carbonate rocks. Unit III is represented by laminated clays and biodetritic limestone. Units IV and V are represented by aragonitic sediments and biomicritic limestones, correlated with the Upper Miocene Topola and Karvuna Formations, respectively. Biogenic silica in the form of diatom frustules and sponge spicules correlates subunit IIa and unit III to the lower and upper parts of the Middle Miocene Euxinograd Formation. Both (sub)units contain organic carbon contents in the order of 1 to 2 wt. % (median: 0.8 for subunit IIa; 1.3 for unit III), locally up to 4 wt. %. Based on Hydrogen Index values (HI) and alkane distribution pattern, the kerogen is mainly type II in subunit IIa (average HI= 324 mg HC/g TOC) and type III in unit III (average HI ~200 mg HC/g TOC). TOC and Rock Eval data show that subunit IIa holds a fair (to good) hydrocarbon generative potential for oil, whereas the upper 5 m of unit III holds a good (to fair) potential with the possibility to generate gas and minor oil. The rocks of both units are immature in the study area. Generally low sulphur contents are probably due to deposition in environments with reduced salinity. Normal marine conditions are suggested for unit III. Biomarker composition is typical for mixed marine and terrestrial organic matter and suggests deposition in dysoxic to anoxic environments.

    Chemical signatures of chromitites are commonly used to track the evolution of the Earth's mantle. However, chemical modification during deformation may have important implications for the interpretation of chromites' signatures. Here, we describe the details of how deformation promotes chemical modification in chromite. Physicochemical characteristics of the chromites were quantified by measuring crystallographic orientation relationships using Electron Back-Scattered Diffraction (EBSD) and electron microprobe analysis (EMP). Chromites show porphyroclastic textures with coarse-grained porphyroclasts (ca. 0.2-5 mm) and fine-grained neoblasts (< 200 μm). Coarse-grained chromites are chemically zoned in terms of major elements from core to rim, preserving this initial igneous feature in the cores, while the outer rims reveal a metamorphic signature. Large chromite grains are characterized by local crystal-plastic deformation, exhibiting distinct inter-crystalline deformation including continuous crystal bending and subgrain boundaries as well as chemical modification in their outer, deformed parts. Two types of fine-grained chromite, F1 and F2, are present. While F1 exhibits a well-developed polygonal texture, straight grain boundaries and low intercrystal misorientation (< 1°), F2 shows low-angle boundaries and significant intercrystalline misorientation (2-8°). Both F1 and F2 have higher Fe3 + and Cr and lower Mg# values than the cores of large grains. We interpret F1 and F2 to represent chromite recrystallized by heterogeneous nucleation and subgrain rotation recrystallization, respectively. Crystallographic preferred orientation (CPO) and misorientation data on the well-developed low-angle (subgrain) boundaries in coarse grains and F2 grains indicate that deformation in chromite was accommodated mainly by dislocation creep with the dominant activation of the {111}<100 > slip system. The retrograde P-T exhumation path predicted by thermodynamic and chemical modeling suggests that these fine-grained chromites were produced when the initial chromitites reacted with oxidizing fluids during retrograde metamorphism ( 1.0 GPa and 500-700 °C). Our results show that deformation in the dislocation-creep regime in a chemically open system has induced chemical modification and homogenization within chromite aggregates as well as strain localization. This close physicochemical link offers new avenues of interpreting the chemical signatures of chromites, utilizing their microstructurally controlled variation or lack thereof.

    Reclaimed soils built in the vicinity of Chukurovo mine are characterized by dynamically changing chemical environment due to the biochemical oxidation of pyrite. Its uneven distribution in soils is a prerequisite for the emergence of macroareas with contrasting biochemical properties and increases the genetic heterogeneity of the studied soils. In these conditions, the interaction between pools and flows of C, N and S in the reclaimed lands is of great interest. To study these processes, we determined the ratios C: N and C: S as indices of mineralization of organic, nitrogen and sulfur compounds in reclaimed soils, the content of phyto- and bioavailable forms of the elements and biomass carbon. The results show that the high content of sulphides delays the humification and mineralization of organic matter through its depressing effect on microbial and plant communities.

    Uranium mining and milling activities adversely affect the microbial populations of impacted sites. The negative effects of uranium on soil bacteria and fungi are well studied, but little is known about the effects of radionuclides and heavy metals on archaea. The composition and diversity of archaeal communities inhabiting the waste pile of the Sliven uranium mine and the soil of the Buhovo uranium mine were investigated using 16S rRNA gene retrieval. A total of 355 archaeal clones were selected, and their 16S rDNA inserts were analysed by restriction fragment length polymorphism (RFLP) discriminating 14 different RFLP types. All evaluated archaeal 16S rRNA gene sequences belong to the 1.1b/Nitrososphaera cluster of Crenarchaeota. The composition of the archaeal community is distinct for each site of interest and dependent on environmental characteristics, including pollution levels. Since the members of 1.1b/Nitrososphaera cluster have been implicated in the nitrogen cycle, the archaeal communities from these sites were probed for the presence of the ammonia monooxygenase gene (amoA). Our data indicate that amoA gene sequences are distributed in a similar manner as in Crenarchaeota, suggesting that archaeal nitrification processes in uranium mining-impacted locations are under the control of the same key factors controlling archaeal diversity.

    This study aimed to determine variations in the dental status of a dentate adult population in terms of “decayed,” “missing,” and “filled” teeth in relation to several sociodemographic and behavioral factors. Quota sampling was used to draw 2531 subjects aged 20 years and over. Data were collected by means of a questionnaire and an oral examination. Multiple logistic regression analyses were performed to observe associations between “decayed,” “missing,” and “filled” teeth and the factors of interest. The mean numbers of “decayed,” “missing,” and “filled” teeth were 2.2, 6.7, and 4.9, respectively. Molar teeth were significantly more often “missing” than premolar and anterior teeth. Age, gender, education, and tooth brushing revealed most noticeable associations. Increasing age was associated with a lower chance of having “decayed” and “filled” teeth, but with a higher chance of having “missing” teeth. Females were more likely to have “missing” and “filled” teeth. Higher education was associated with a lower chance of having “missing” teeth. More frequent tooth brushing was associated with a lower chance of having “decayed” and “missing” teeth, but with a higher chance of having “filled” teeth. These risk indicators should be considered in prevention program planning if reduction of tooth loss is to be achieved. PMID:22654908

    The aim of this work is to study the epidemiology and antimicrobial resistance to the most commonly used antibiotics for the treatment of acute gastroenteritis caused by Salmonella and Shigella at the largest Bulgarian hospital-University Hospital "St. George," Plovdiv-for the period 2009-2013. Two hundred ninety strains were in vitro tested for resistance to 15 antimicrobial agents. The presence of extended-spectrum beta-lactamases (ESBLs) was demonstrated by a variety of specialized tests. For comparison, a collection of 28 strains submitted by the National Reference Laboratory (NRL) "Enteric Infections" at the National Center of Infectious and Parasitic Diseases (NCIPD), Sofia, was also tested for the production of ESBLs. In isolates, phenotypically demonstrated as ESBL producers, polymerase chain reaction (PCR) detection of the genes bla-CTX-M, bla-SHV, and bla-TEM was performed. Among the 290 tested isolates, only two- Salmonella serotype Livingstone and Shigella flexneri-were phenotypically proven to be ESBL producers. Only 4 strains from the collection of 28, submitted from the NRL "Intestinal Infections" in NCIPD, Sofia, were phenotypically confirmed as ESBL producers. The presence of the bla-CTX-M gene was detected in all of the tested strains (4 from NRL, NCIPD, Sofia, and 2 from the University Hospital St. George, Plovdiv), the bla-SHV gene only in strain S. Livingstone from Plovdiv, and the bla-TEM gene in two from Sofia and one (again S. Livingstone) from Plovdiv. In conclusion, Salmonella and Shigella isolates from patients hospitalized at the University Hospital St. George, Plovdiv, with acute gastroenteritis demonstrate good susceptibility to the most commonly used antibiotic agents, including azithromycin.

    The Rhodope Metamorphic Complex is a stack of allochthons assembled during obduction, subduction, and collision processes from Jurassic to Paleogene and overprinted by extensional detachment faults since Middle Eocene. In the study area, the following nappes occur in superposition (from base to top): an orthogneiss-dominated unit (Unit I), garnet-bearing schist with amphibolite and serpentinite lenses (Unit II), greenschist, phyllite, and calcschist with reported Jurassic microfossils (Unit III), and muscovite-rich orthogneiss (Unit IV). U-Pb dating of zircons from a K-feldspar augengneiss (Unit I) yielded a protolith age of ca. 300 Ma. Garnet-bearing metasediment from Unit II yielded an age spectrum with distinct populations between 310 and 250 Ma (detrital), ca. 150 Ma, and ca. 69 Ma (the last two of high-grade metamorphic origin). An orthogneiss from Unit IV yielded a wide spectrum of ages. The youngest population gives a concordia age of 581 ± 5 Ma, interpreted as the age of the granitic protolith. Unit I represents the Lower Allochthon (Byala Reka-Kechros Dome), Unit II the Upper Allochthon (Krumovitsa-Kimi Unit), Unit III the Uppermost Allochthon (Circum-Rhodope Belt), and Unit IV a still higher, far-travelled unit of unknown provenance. Telescoping of the entire Rhodope nappe stack to a thickness of only a few 100 m is due to Late Eocene north directed extensional shearing along the newly defined Kulidzhik Detachment which is part of a major detachment system along the northern border of the Rhodopes. Older top-to-the south mylonites in Unit I indicate that Tertiary extension evolved from asymmetric (top-to-the-south) to symmetric (top-to-the-south and top-to-the-north), bivergent unroofing.

    Fine particulate matter PM2.5 and PM10 air pollutants are a serious problem in many urban areas affecting both the health of the population and the environment as a whole. The availability of large data arrays for the levels of these pollutants makes it possible to perform statistical analysis, to obtain relevant information, and to find patterns within the data. Research in this field is particularly topical for a number of Bulgarian cities, European country, where in recent years regulatory air pollution health limits are constantly being exceeded. This paper examines average daily data for air pollution with PM2.5 and PM10, collected by 3 monitoring stations in the cities of Plovdiv and Asenovgrad between 2011 and 2016. The goal is to find and analyze actual relationships in data time series, to build adequate mathematical models, and to develop short-term forecasts. Modeling is carried out by stochastic univariate and multivariate time series analysis, based on Box-Jenkins methodology. The best models are selected following initial transformation of the data and using a set of standard and robust statistical criteria. The Mathematica and SPSS software were used to perform calculations. This examination showed measured concentrations of PM2.5 and PM10 in the region of Plovdiv and Asenovgrad regularly exceed permissible European and national health and safety thresholds. We obtained adequate stochastic models with high statistical fit with the data and good quality forecasting when compared against actual measurements. The mathematical approach applied provides an independent alternative to standard official monitoring and control means for air pollution in urban areas.

  10. Sedimentology of Hirnantian glaciomarine deposits in the Balkan Terrane, western Bulgaria: Fixing a piece of the north peri-Gondwana jigsaw puzzle

    Chatalov, Athanas

    2017-04-01

    Glaciomarine deposits of late Hirnantian age in the western part of the Palaeozoic Balkan Terrane have persistent thickness ( 7 m) and lateral uniformity in rock colour, bedding pattern, lithology, and sedimentary structures. Four lithofacies are distinguished from base to top: lonestone-bearing diamictites, interbedded structureless mudstones, crudely laminated diamictites, and finely laminated mudstones. The diamictites are clast-poor to clast-rich comprising muddy to sandy varieties. Their compositional maturity is evidenced by the very high amount of detrital quartz compared to the paucity of feldspar and unstable lithic grains. Other textural components include extraclasts derived from the local Ordovician basement, mudstone intraclasts, and sediment aggregates. Turbate structures, grain lineations, and soft sediment deformation of the matrix below larger grains are locally observed. Sedimentological analysis reveals that deposition occurred in an ice-intermediate to ice-distal, poorly agitated shelf environment by material supplied from meltwater buoyant plumes and rain-out from ice-rafted debris. Remobilization by mass-flow processes (cohesive debris flows and slumps) was an important mechanism particularly for the formation of massive diamictites. The glaciomarine deposits represent a typical deglaciation sequence reflecting retreat of the ice front (grounded or floating ice sheet), relative sea-level rise and gradually reduced sedimentation rate with increasing contribution from suspension fallout. This sequence was deposited on the non-glaciated shelf of the intracratonic North Gondwana platform along the southern margin of the Rheic Ocean. The Hirnantian strata of the Balkan Terrane can be correlated with similar glaciomarine deposits known from peri-Gondwana terranes elsewhere in Europe showing clear 'Armorican affinity'. Several lines of evidence suggest that the provenance of siliciclastic material was associated mainly with sedimentary recycling of mature sands which had been deposited across North Gondwana in Cambrian and pre-glacial Ordovician times.

    Head-and-neck infections often involve anaerobes such as Prevotella species. Aim of the present study was to assess the evolution and the factors associated with resistance in Prevotella species to penicillin, clindamycin, metronidazole, tetracycline and β-lactams/β-lactamase inhibitors (BL/BLIs). In total, 192 Prevotella strains, isolated from patients with oral and head-and-neck infections, were evaluated. Common isolates were Prevotella intermedia and Prevotella melaninogenica within the pigmented species as well as Prevotella oris and Prevotella oralis group within the non-pigmented species. Overall resistance was 43.2% for penicillin, 10.9% for clindamycin, 0% for metronidazole. Nonsusceptibility to tetracycline was 29.1% without significant differences in resistance rates between pigmented and other species. Penicillin resistant strains were β-lactamase positive. From 2003-2004 to 2007-2009, penicillin resistance rates increased about four-fold (from 15.4% to 60.6%). Clindamycin resistance did not show evolution, whereas tetracycline nonsusceptibility decreased from 43.3% in 2003-2004 to 20.7% in 2007-2009. Except for one (0.5%) P. oralis strain with intermediate susceptibility to BL/BLIs, the other strains were susceptible to the agents. In conclusion, in Prevotella strains from patients with head-and-neck infections, the resistance rate to penicillin increased, that to clindamycin remained stable and the nonsusceptibility rate to tetracycline decreased during the period. Activity against >99% of Prevotella strains was observed with metronidazole and BL/BLIs. The penicillin resistance and tetracycline nonsusceptibility were associated with the year of study, national antibiotic consumption and possibly with previous treatment (for tetracycline). The evolution of penicillin resistance in Prevotella strains was highly dynamic.

    Three-axis stabilization of the satellite orientation ensured success for convenient measurements both of electric and magnetic field vectors. X axis was directed along the satellite orbital velocity vector. Z axis was directed upwards, perpendicular to the Earth's surface. Fast flows of electrons and ions were measured in the directions along both +z and -z axes and also perpendicular to z axis. Ionospheric ion concentration meters registered sharp changes of the plasma density. Taking into account the totality meter set data we can conclude that the physical phenomena observed in these measurements are caused by damping both of electrostatic oscillations and plasma vortices. Also it is shown that large-scale irregularity rise and disintegration into small-scale irregular structures can be connected with magnetospheric and ionospheric sources.

    Isotopic data obtained from human remains can provide information about an individual's origin, migration, and diet. We evaluate the usefulness of carbon, oxygen, strontium, and lead isotopes for forensic investigations by comparing data from Bulgarian teeth with data from other regions. Geo-referencing based on oxygen or strontium isotopes can be misleading due to overlap with other countries in Europe and other continents. Carbon and lead isotopes, in combination with oxygen and strontium isotopes, provide the most useful information for identification of local vs foreigner status. In particular, high-precision Pb isotopes show a distinct "Bulgarian" range; however, it is possible that individuals from other countries in Eastern Europe and/or central to western Asia could have overlapping isotopic values. Additional high-precision multi-isotope data from modern humans from different regions in the world are required to transition from speculative to more quantitative estimation of a geographical place of origin for unidentified human remains.

    A pneumococcal conjugate vaccine (PCV10) was introduced in Bulgarian national immunization program since April 2010. Clonal composition based on pulsed-field gel electrophoresis and multilocus sequence typing genotyping of 52 serotype 19A Streptococcus pneumoniae isolates was analyzed. These were invasive and respiratory isolates collected between 1992 and 2013 from both children (78.8% <5 years) and adults with pneumococcal infections. Multidrug resistance was found in 82.7% of all 19A isolates. The most prevalent genotype (63.5%) among serotype 19A pneumococcal strains was the multidrug-resistant clonal complex CC230, which is a capsular switched variant of the Denmark(14)-32 (ST230) global clone. The most frequent sequence type (ST) was ST230 (48.1%) and together with four other closely related STs (15.4%), belonging to ST1611, ST276, ST7466, and ST2013, which were single- and double-locus variants; they were included in the main CC230. The disappearance of highly drug-resistant ST663 clone and emergence of new clones as CC320 and CC199 was also observed among the rest 19A isolates. A comparison of clonal composition between invasive and noninvasive isolates did not show a great genetic diversity among both kinds of isolates. Continuous surveillance of serotype 19A population following the introduction of PCV10 is essential to evaluate the impact of the vaccine on the epidemiology of this serotype.

  3. Archaeo-directional and -intensity data from burnt structures at the Thracian site of Halka Bunar (Bulgaria): The effect of magnetic mineralogy, temperature and atmosphere of heating in antiquity

    Archaeomagnetic results are presented from a series of burnt structures at the Thracian site of Halka Bunar. Archaeointensity and archaeodirectional studies were undertaken on three kilns from a pottery production complex. This has been dated to the late 4th and early 3rd century B.C. (325-280 B.C.) based on coins found associated with the kilns [Tonkova, M., 2003. Newly discovered Thracian Centre of the Early Hellenistic Age at the Spring "Halka Bunar" in the Land of C. Gorno Belevo. Annuary of the Institute of Archaeology with Museum. Bulgarian Academy Sci. 2, 148-196 (in Bulgarian)]. This data provides a new point for the Bulgarian archaeomagnetic curve (Dec: 348.70 ± 5.79, Inc: 62.20 ± 2.70, and Fa: 77.23 ± 2.17 μT). The kilns are thought to have been used for producing different types of pottery in a range of heating atmospheres and at different temperatures. Therefore, special attention was paid to the magnetic mineralogy of the samples and its effect on the palaeodata. Kiln 3, orange clay samples were dominated by fine to ultra-fine grained single domain and superparamagnetic magnetite, with a small proportion of haematite. The samples were heated in a high temperature oxidising environment. Kiln 2 was probably used to make grey ware pottery. The samples are light grey and were dominated by stable single domain magnetite formed by high temperature heating in a more reducing environment. Kiln 4, mottled samples consisted of a variable mineralogy showing characteristics of both Kiln 2 and Kiln 3 samples. It was probably used to make traditional, mottled, Thracian ware pottery and was heated to lower temperatures in a mixed environment of heating. Samples heated in an oxidising environment gave more reliable Thellier results than samples heated in a reducing environment in antiquity, as the latter altered heavily on re-heating. A fourth kiln and a destruction feature from different trenches than the kiln complex were also investigated to establish their age. Archaeodirectional data was not recoverable from these two structures due to post-burning disturbance. The mean archaeointensity from Kiln 5 (mean 78.0 ± 1.7 μT) is consistent with that from the main kiln complex (mean 77.23 ± 2.17 μT) and is therefore considered to be contemporary. It was probably not used to make pottery. The destruction feature records much lower archaeointensity values (mean 65.1 ± 1.1 μT). When this value is compared to the existing reference points of the Bulgarian database it suggests this feature is younger than the kilns (250-140 B.C.). Multiple age use of the site is therefore confirmed with a main period of occupation in the late 4th and early 3rd century B.C. and another phase of occupation in the mid 3rd to mid 2nd century B.C.

  4. Petrology, geochemistry and Sm-Nd analyses on the Balkan-Carpathian Ophiolite (BCO - Romania, Serbia, Bulgaria): Remnants of a Devonian back-arc basin in the easternmost part of the Variscan domain

    The pre-Alpine basement of the Southern Carpathians/Western Balkans contains four ophiolitic massifs dismembered by Alpine tectonics, which define the ;Balkan-Carpathian Ophiolite; (BCO) for which the tectonic setting and age of formation are still debated (Precambrian or Early Devonian). In this contribution, we demonstrate that, in light of a Pre-Alpine restoration, the four massifs belonged to a unique slice of very complete, obducted oceanic lithosphere and we re-evaluate its tectonic setting. Large chromitite volumes with Al-rich spinel compositions (Cr# = 0.39-0.48), as well as major and trace geochemical results on basalts (slightly enriched N-MORBs with low negative Nb anomaly associated with calk-alkaline BABBs), point to a formation in a back-arc basin. Mantle spinel composition (Cr# = 0.49-0.51) and melting modeling indicate mean melting extents of 8.5-11% favouring intermediate spreading rate. New Sm-Nd dating on lower gabbroic rocks give a whole rock isochron, interpreted as the age of formation of the BCO crust at 409 ± 38 Ma, thus confirming an Early Devonian oceanic crust. The previous ∼563 Ma U-Pb zircon age can be interpreted as casual inheritance indicating the proximity of an old continental lithosphere. Taking into account the lithological evidences and paleocontinental affinities of the two recognized terranes separated by the BC oceanic basin (Balkans and Sredna Gora) and by analogy with other Variscan ophiolites in Western/Central Europe, we suggest that the BC ophiolite belong to the ∼400 Ma ophiolites group obducted between West and East Galatia and belonging to the southern Variscan suture. However, the BC ophiolite is the only one of this group obducted to the north and not involved in the Lower Allochthon/ophiolite/Upper Allochthon thrust pile, likely explaining its exceptional preservation. Finally, we tentatively propose a new unifying tectonic model where different terrane drift rates and highly oblique displacements create two Rheic branches, the ;Rheic; and the ;Galicia-Brittany-Massif Central;.

    We examine how ordinary citizens in Bulgaria view the developmental levels of European countries and certain states outside of Europe. Our research is motivated by the understanding that scholars and policy makers have for centuries used developmental hierarchies to characterize countries and that this perception of differential development has shaped interactions among different groups, countries and regions. We expect that views of such developmental hierarchies and models have great potential for influencing demographic and family behavior and political and cultural identities of ordinary people. Using data from a 2009 survey in Bulgaria we document that developmental hierarchies are widely perceived in Bulgaria, but are distributed differentially by age, education, and degree of urbanization. We also consider internal mechanisms underlying this hierarchical understanding of development and how hierarchical understandings may be related to national identities.

    Coastal protected areas and historical heritage sites in Bulgaria are established by national policy instruments/laws and EU Directives to protect a wide range of natural and cultural resources along the coast. Within the framework of HERAS Project (Submarine Archaeological Heritage of the Western Black Sea Shelf), financed by European Union under the CBC Program Romania-Bulgaria, we made an inventory and identification of protected areas, nature reserves, monuments, parks and onshore historical sites along the North Bulgarian coast (NUTS III level). The adjacent coastline is 96 km long between cape Sivriburun to the border of Romania on the north and cape Ekrene on the south. Coastal zone here is mostly undeveloped and low urbanized compared to other coastal regions in Bulgaria. It comprises of large sand beaches, vast sand dunes, up to 70 m spectacular high limestone cliffs, coastal fresh-water lakes, wetlands etc. This coastal section includes also one of the most important wetlands and it is migration corridor for many protected birds in Bulgaria, that host one of the rarest ecosystem types with national and international conservational value. Added to ecosystem values, the region is also an archeologically important area, where numerous underwater and coastal archaeological sites from different periods have been discovered - Prehistory, Antiquity (ancient Greek, Hellenistic, Roman), Mediaeval (Early Byzantium, Bulgarian). Research was made within 2100 m zone from the coastline (in accordance with zones defined by the Black Sea Coastal Development Act) for territories with protected status in the framework of many national laws and EU Directives. The total area of this strip zone is 182, 6 km2 and around 67% is under protection. There are 11 unique NATURA 2000 protected areas (6 Special Protection Areas (SPAs) and 5 Sites of Communities Importance (SCI), 2 nature reserves and 1 Nature Park. Some of them are also onshore historical sites. In Bulgaria such sites

  15. Bulgarian Turkish emigration and return.

    PubMed

    Vasileva, D

    1992-01-01

    The main factors which determined the 1989 migration of Turks in Bulgaria back to Turkey are discussed. Background history is provided. After World War I, Turks in bulgaria comprised 10% of the total population. Bulgarian policy had been, up to the 1980s to send Rumelian Turks back, but the policy after 1980 was one of a national revival process to integrate Turks into the developed socialist society. Muslim traditions, customs, and Turkish language were interfered with. International disfavor resulted. In May 1989, the Communist Party declared, in an effort to show democratic ideals, open borders. Thus began the new emigration wave. 369,839 people fled to the Turkish border. 43% of the 9.47 ethnic Turks in bulgaria went to Turkey within 4 months. The numbers decreased in November, and soon after the communist regime ended. New laws were adopted allowing Turks to assume their original Turkish names. The huge migration was clearly political, and as such, the emigrant Turks should be determined as refugees and asylum seekers. The provocation of ethnic Turks was used by the communist regime to solve potential social conflicts. Not only did Turks flee to escape from violence or for religious, cultural, and moral reasons but also due to free market initiatives begun in Turkey in the early 1980s which improved Turkish quality of life. Food and consumer goods were cheaper and economic advantages were perceived. Emigrants were primarily peasants with lower levels of education, professional qualifications, and labor skills. 154,937 (42%) returned to bulgaria and 58% stayed in Turkey to comprise 25% of the former Turkish population. During this period, tensions between countries was high.l Bulgarians actively encouraged emigration and Turkey welcomed it. The emigrants to Turkey were seen as foreigners (muhacir or gocmen) but were received with good will and were readily accepted into menial positions. Emigrants were confronted with political, linguistic, and cultural

  16. Using principal component analysis and general path seeker regression for investigation of air pollution and CO modeling

    2015-10-01

    The monitoring and control of air quality in urban areas is important problem in many European countries. The main air pollutants are observed and a huge amount of data is collected during the last years. In Bulgaria, the air quality is surveyed by the official environmental agency and in many towns exceedances of harmful pollutants are detected. The aim of this study is to investigate the pollution from 9 air pollutants in the town of Dimitrovgrad, Bulgaria in the period of 5 years based on hourly data. Principal Component Analysis (PCA) is used to discover the patterns in the overall pollution and the contribution of the 9 pollutants. In addition the Generalized Path Seeker (GPS) regularized regression method is applied to find dependence of CO (carbon monoxide) with respect to other pollutants and 8 meteorological parameters. It is reported that the CO concentrations are in continuously repeated low level quantities very harmful for human health.

    2013-01-01

    Abstract The karyotype and meiosis in males of giant water bug Lethocerus patruelis (Heteroptera: Belostomatidae: Lethocerinae) were studied using standard and fluorochrome (CMA3 and DAPI) staining of chromosomes. The species was shown to have 2n = 22A + 2m + XY where 2m are a pair of microchromosomes. NORs are located in X and Y chromosomes. Within Belostomatidae, Lethocerus patruelis is unique in showing sex chromosome pre-reduction in male meiosis, with the sex chromosomes undergoing reductional division at anaphase I and equational division at anaphase II. Cytogenetic data on the family Belostomatidae are summarized and compared. In addition, the structure of the male internal reproductive organs of Lethocerus patruelis is presented, the contemporary distribution of Lethocerus patruelis in Bulgaria and in the northern Aegean Islands is discussed, and the first information about the breeding and nymphal development of this species in Bulgaria is provided.

    The subject concerns the unrecognised European Bulgaria whose the alone museum of History of Medicine is worth of seeing. The 1869 building is of an ancient hospital which reminds of the hundred-year-old history of the modern Bulgaria. The miscellance of the objects, the strictness and the clearness of the show afford to follow through five rooms the development of Medicine as practice, art and science from Antiquity till the Second World War. The interest stemming from the general character of the museum is underlined by the constant references to the evolution of the Bulgarian Medicine. Then the local specific characteristics could totally integrate into the evolution of European Medicine. The role of France in the education of the first Bulgarian practitioners is worth reminding. The visitors get out of the museum through a delightful garden rich in Medicinal plants.

  20. Ethnic and religious differentials in Bulgarian mortality, 1993–98

    PubMed Central

    Kohler, Iliana V.; Preston, Samuel H.

    2011-01-01

    We investigated ethnic/religious mortality differentials in Bulgaria during the 1990s. The analyses employed a unique longitudinal data set covering the entire population of Bulgaria from the census of 1992 until 1998. The mortality of Roma is very high compared to all other ethnic/religious groups. The excess applies to nearly every cause of death examined and is not entirely explained by the adverse location of Roma on social and economic variables. For young men, Muslim mortality is substantially lower than that of non-Muslims when socioeconomic differences are controlled. An analysis of causes of death suggests that lower consumption of alcohol may contribute to this ‘Muslim paradox’. For older Muslim women, a significant mortality disadvantage remains after controls are imposed. Suicide mortality is lower for Muslims than for Christian groups of the same ethnicity. Consistent with deteriorating economic conditions over the study period, mortality was rising, particularly for women. PMID:21294054

    Fillers for lip augmentation have become more and more popular in recent years and seem to be indispensable in the cosmetic market nowadays. A series of six young females is presented who developed massive swellings and pain after vitamins A and/or E lip augmentation. The vitamins were extracted from gelatinous capsules (Gericaps [Adipharm EAD, Sofia, Bulgaria], Geritamins [Actavis EAD, Balkanpharma-Dubnitsa AD, Bulgaria], or vitamin E yellow gel capsules) and injected by unprofessional physicians and beauticians in different cosmetic centers. Physical examination revealed firm indurations of the lips and perioral skin, tenderness, erythema, and hard dermal nodules. Histological analysis revealed numerous round-to-ovoid cavities of varying sizes, resulting in a Swiss cheese-like appearance, consistent with lipogranulomas. The patients were treated with systemic and intralesional triamcinolone injections and broad-spectrum antibiotics with good clinical response. In conclusion, these cases demonstrate the danger of the use of unregistered products as fillers injected by unprofessional physicians and beauticians.

  10. Onychomycosis in patients with psoriasis--a multicentre study.

    PubMed

    Zisova, L; Valtchev, V; Sotiriou, E; Gospodinov, D; Mateev, G

    2012-03-01

    1-3% of human population is affected by psoriasis. Nail disorders are reported in 10-80% of patients with psoriasis. Nail deformations vary according to their degree of severity but are mainly represented by pitting, Beau's lines, hyperkeratosis, onycholysis, leuconychia or oil drops. Onychomycosis is a fungal infection of the nails, caused by dermatophytes, yeast and moulds. In this study, 228 patients with psoriasis aged between 18 and 72 were examined (48 - from Plovdiv, Bulgaria; 145 - from Pleven, Bulgaria and 35 - from Thessaloniki, Greece); 145 of them were male and 83 of them were female. The examination of the nail material was performed via direct microscopy with 20% KOH and nail samples plated out on Sabouraud agar methodology. The severity of the nail disorders was determined according to the Nail Psoriasis Severity Index (NAPSI). Positive mycological cultures were obtained from 62% of the patients with psoriasis (52%- Plovdiv, Bulgaria; 70%- Pleven, Bulgaria and 43%- Thessaloniki, Greece). In 67% of the cases, the infection was caused by dermatophytes, in 24% by yeast, in 6% by moulds and in 3% by a combination of causes. All patients with psoriasis were identified with high levels of NAPSI, whereas the ones with isolated Candida had even higher levels. Seventeen percentage of the patients have been treated with methotrexate, 6% have been diagnosed with diabetes and 22% have been reported with onychomycosis and tinea pedis within the family. An increased prevalence of onychomycosis among the patients with psoriasis was found. Dystrophic nails in psoriasis patients are more predisposed to fungal infections. The mycological examination of all psoriasis patients with nail deformations is considered obligatory because of the great number of psoriasis patients diagnosed with onychomycosis.

  19. Astronomy in the Bulgarian Neolithic

    NASA Astrophysics Data System (ADS)

    Stoev, Alexey; Maglova, Penka

    Bulgaria is famous for the richness of its Neolithic culture, with its large variety of artistic representations having deep semantic meaning. Here, we consider several types of monument which yield evidence for the astronomical practices and beliefs of Neolithic and Eneolithic (Chalcolithic) peoples. We begin by considering the emergence and development of Neolithic and Eneolithic societies in Bulgaria and the chronological development of material and spiritual culture. By discussing specific monuments it is shown how astronomy was woven into everyday and spiritual life, revealing insights into people's concepts of space and time. The monuments concerned are Karanovo, the largest and one of the oldest tells in Europe; Topchika cave, with the earliest rock pictures; Magura cave, one of the largest and most beautiful caves in Bulgaria, famous for its unique paintings; Bailovo cave complex, with its lunar images and calendar frieze composed of monochrome paintings; and the Tangarduk Kaya cave sanctuary, from which observations could have been made of the culmination of the sun on the meridian at the solstices.

  20. Acculturation orientations mediate the link between religious identity and adjustment of Turkish-Bulgarian and Turkish-German adolescents.

    2016-01-01

    There is a growing recognition of the need to examine religiousness and conduct research on its influence on acculturation and adjustment among ethnic minorities (Güngör et al. in Int J Behav Dev 36:367-373, 2012. doi:10.1177/0165025412448357). The present study compares Turkish minority youth in Bulgaria and Germany by examining relationships among religious identity, acculturation orientations (i.e., cultural maintenance and adoption) and acculturation outcomes (i.e., life satisfaction and socio-cultural adjustment to the Turkish and mainstream cultures). Participants were 161 youth in Bulgaria and 155 in Germany who completed measures on religious identity, acculturation orientations and adjustment. Results revealed that religious identity and Turkish culture maintenance are more important for Turkish-German, than for Turkish-Bulgarian youth. A multigroup path model showed that for both samples acculturation orientations partially mediated the link between religious identity and adjustment to the Turkish culture, whereas religious identity was directly related both to adjustment to the mainstream culture and to life satisfaction. Findings highlight the centrality of religious identity and Turkish domains of acculturation for positive adjustment outcomes for Turkish youth in Bulgaria and Germany.
