to provide a methodologically robust and in-depth exploration of maternal expectations and beliefs in a non-clinical sample of Bulgarian mothers who described their ideas about motherhood postnatally. qualitative study using face to face interviews for data collection. the cities of Sofia and Varna, Bulgaria. 10 women, 7 primiparae and 3 multipara, aged 28-32 years, who gave birth within the last 18 months. interviews were carried out using a semi-structured schedule. Discussions were audio-recorded with participants' consent, translated and transcribed. Thematic analysis was used under the contextualist theoretical framework. four general themes of women's expectations about motherhood were identified, concerning expectations of motherhood, parenting self-confidence, beliefs about the mother-infant dyad and anticipated social support. Findings suggest that there was a substantial discrepancy between expectations and the reality of motherhood, for primiparae and multipara mothers. Unrealistic expectations about motherhood were related to a more difficult postnatal adjustment, lowered self-esteem and feelings of inadequacy. the way in which women view themselves as mothers during pregnancy can have a significant impact on their emotional well-being following birth. The implications of these findings are discussed with particular reference to promoting a successful adjustment to motherhood through appropriate antenatal care, focussing on maternal expectations about their new role.

The aim of this study was to analyze the beta-lactamases and the molecular epidemiology of 19 clinically significant isolates of Proteus mirabilis with decreased susceptibility to imipenem, which have been collected from seven hospitals, located in different Bulgarian towns (Sofia, Varna, and Pleven). The isolates were obtained from blood, urine, tracheal and wound specimens. One additional isolate from hospital environment was included. 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 PFGE. Integron mapping was performed by PCR and sequencing. All isolates showed a multidrug-resistance profile, but remained susceptible to piperacillin/tazobactam, cefepime, meropenem, and fosfomycin. They produced identical beta-lactamases, namely: TEM-1, VIM-1, and CMY-99. PCR mapping revealed that the bla VIM-1 gene was part of a class 1 integron that additionally included the aac(6')-I, dhfrA1, and ant(3″)-Ia genes. In addition, 17 of the isolates carried the armA gene. Conjugation experiments and plasmid replicon typing were unsuccessful. The isolates were clonally related according to RAPD and PFGE typing. This study reveals the nationwide distribution of a multidrug-resistant P. mirabilis clone producing VIM-1 and CMY-99 along with the presence of different aminoglycoside resistance mechanisms.

Forty-two extended-spectrum beta-lactamase (ESBL)-producing isolates of Enterobacter aerogenes, Enterobacter cloacae, Pantoea agglomerans, and Serratia marcescens, collected consecutively during the period January-November 2011 from the University Hospital in Varna, Bulgaria, were studied to characterize their ESBLs by isoelectric focusing, group-specific PCR, and sequencing. The epidemiological relationship was evaluated by random amplified polymorphic DNA analysis (RAPD). Transferability of ESBL genes was determined by conjugation experiments. Plasmid analysis was done by replicon typing and PstI fingerprinting. The overall rate of ESBL production was 20%. The most widespread enzyme was CTX-M-3, found in 64%. It was dominant in E. aerogenes (100%) and S. marcescens (83%). SHV-12, CTX-M-3, and CTX-M-15 were found among E. cloacae isolates in 50%, 35%, and 45%, respectively. Three main CTX-M-3-producing epidemic clones of E. aerogenes and S. marcescens have been detected. Among E. cloacae isolates, six different RAPD profiles were discerned. The plasmids harboring blaCTX-M-3 belonged to IncL/M type and demonstrated similar PstI fingerprinting profiles. IncFII plasmids were detected in two CTX-M-15-producing E. cloacae isolates. Our results demonstrate wide intrahospital dissemination of clonal E. aerogenes and S. marcescens isolates, carrying IncL/M conjugative plasmids.

In the last 40 years, physical and rehabilitation medicine (PRM) has made significant steps forward in Europe with the foundation of the European Federation of Physical Medicine and Rehabilitation (EFPMR) (1963) which gave rise to the European Society of Physical and Rehabilitation Medicine (ESPRM) (2004) the European Academy of Rehabilitation Medicine (1970), the PRM Section of the European Union of Medical Specialists (1974), and the European Board of PRM (1991). Our journal, formerly Europa Medico-physica (1964), the official journal of the EFPMR, now European Journal of Physical and Rehabilitation Medicine (EJPRM) and official journal of the ESPRM since 2008, is distinct for its steadfast European vocation, long-standing Mediter-ranean interests and connections with various national scientific societies. Jointly with the ESPRM, efforts are under way to set up the European Physical and Rehabilitation Medicine Journal Network (EPRMJN). The aim of this article is to present a profile of the national journals in the EPRMJN so as to give a better overview of how the scientific part of PRM in Europe has developed within a national perspective. A profile of the following national journals is presented: Annals of Physical and Rehabilitation Medicine (France), Fizikalna i rehabilitacijska medicina (Physical and Rehabilitation Medicine) (Croatia), Neurorehabilitation (Bulgaria), Physical and Rehabilitation Medicine Portuguese Society Journal (Portugal), Physical Medicine, Rehabilitaton, Health (Bulgaria), Physikalische Medizin - Rehabilitationsmedizin - Kurort-medizin/Journal of Physical and Rehabilitation Medicine (Germany and Austria) Prevention and Rehabilitation (Bulgaria), Rehabilitacija (Rehabilitation) (Slovenia), Rehabilitación (Madr) (Spain), Turkish Journal of Physical Medicine and Rehabilitation (Turkey). Some national journals in Europe have a very long history and tradition of research and education. Having a better knowledge of these realities, usually hidden to the international readership owing to the English language barrier, could promote science in our specialty.

Ancient Indian mental concepts of children and adolescents are very similar to the contemporary modern concepts. The ancient concepts were based on a very positive regard for the children's development, education and future independence, adult role and contribution to society. Children were wanted and considered precious. The children were categorized in to 4 different varnas based on their intelligence, abilities, merit and aptitude and educated accordingly, away from their home, at Gurukuls. They had universal right to education. Girls received attention equal to boys. The boys were expected to earn their livelihood, while the girls were expected to be homemakers. Graduation of the young person at the end of education and return to home marked the emancipation from adolescence. Children's physical and mental health and its disorders were given due attention. Aetiology and treatment of physical and mental disorders was in accordance with the overall scientific development of those times.

Changes of Bulgarian Coastal Dune Landscape under Anthropogenic Impact

At one time large sand dune formations were widely distributed along the Bulgarian coast. However, due to increased urbanization in the coastal zone, the areas of total dune landscape has been constantly reduced. Dunes presently comprise only 10% of the entire 412 km long coastline of Bulgaria: they embrace a total length of 38.57 km and a total area of 8.78 km2 Important tasks in dune protection are identification of landscape changes for a certain period of time and accurate delineation of sand dune areas. The present research traces sand dune changes along the Bulgarian Black Sea coast over a 27 year period (1983-2010). This period includes also the time of expanded tourist boom and overbuilding of the coastal zone, and respectively presents the largest dune changes and reductions. Based on the landscape change analyst in GIS environment the study also aims to explore the importance of different natural and human factors in driving the observed dune alterations and destruction. To detect and assess dune changes during the last 3 decades, we used data for sand dunes derived from several sources at different time periods in order to compare changes in shoreline positions, dune contours and areas: i) Topographic maps in 1:5,000 scale from 1983; ii) Modern Very High Resolution orthophotographs from 2006 and 2010; iii) QuickBird Very High Resolution satellite images from 2009; iv) Statistical information for population and tourist infrastructure is also used to consider the influence of human pressure and hotel developments on the dune dynamics. In addition, for more detailed description and visualization of main dune types, digital photos have been taken at many parts of the Bulgarian coast. The study was performed in GIS environment. Based on the results obtained the dunes along the Bulgarian coast were divided into three main groups with relation to the general factors responsible for their alterations: i) Dunes that have decreased in result of shoreline retreat and erosion of the beach itself. Typically dunes are located behind sand beaches and they are part of the beach-dune systems. Such type of dune reduction could be driven by combination of many factors, both natural ones (such as severe storms, erosion, heavy rains or flooding) and human impacts (large number of installed coast-protection structures along the coast, which interrupt the sediment transport, create new sedimentary deficit and generate erosion). During the recent years most of the Bulgarian beaches have progressively eroded and their areas have significantly been decreased. ii) Dunes that have been reduced/damaged and lost due to expanded tourist and housing infrastructures/developments and due to afforestaion activities. The principal sources of human impacts on sand dunes in Bulgaria are rapid coastal urbanization over the recent years (i.e., hotel and residential constructions, roads, parking structures, and other related infrastructure), unregulated camping and "temporary" constructions on the dunes, a lax regulatory environment that tolerates the re-zoning of protected sand dunes to "agricultural" areas. At most recreational sites there were wide coastal dunes, which however have been destroyed during tourist constructions. Such are dunes at the most famous Bulgarian sea resorts of Golden Sands and Sunny Beach in the areas of Varna and Nessebar. As a consequence, major areas along the Bulgarian coast were completely urbanized by hotels and other infrastructures and large sand dune systems were damaged. iii) Dunes located at still undeveloped coastal sections: yet they are naturally preserved and unthreatened by human pressure boom. These are just a few dune sites: at the northernmost portion of the Bulgarian coast (in the area of Durankulak), at the central part in the region of the largest Bulgarian river, Kamchia River, and along the southernmost coastline (in the area of Veleka River). Although sand dunes in Bulgaria are protected areas and national reserves they have been exposed to large anthropogenic pressure in particular over the last decade. There is an increased demand now of proper management and urgent conservation activities. Such measures first require an accurate understanding of dune properties/behaviour, assessment of anthropogenic factors affecting dune persistence and identification of coastal areas most sensitive to risk of destruction. This research has been undertaken with the support of National Science Fund - Ministry of Education, Youth and Science, (Republic of Bulgaria); Contract No: DNTS 02/11 from 29.09.2010 in the frame of a Joint Research Project between Bulgaria and Romania (2010-2012). The Ministry of Agriculture and Food (Republic of Bulgaria) is deeply acknowledged for providing the modern orthophoto and satellite image data needed and useful also for implementation of the project activities.

Previous studies that pooled Indian populations from a wide variety of geographical locations, have obtained contradictory conclusions about the processes of the establishment of the Varna caste system and its genetic impact on the origins and demographic histories of Indian populations. To further investigate these questions we took advantage that both Y chromosome and caste designation are paternally inherited, and genotyped 1,680 Y chromosomes representing 12 tribal and 19 non-tribal (caste) endogamous populations from the predominantly Dravidian-speaking Tamil Nadu state in the southernmost part of India. Tribes and castes were both characterized by an overwhelming proportion of putatively Indian autochthonous Y-chromosomal haplogroups (H-M69, F-M89, R1a1-M17, L1-M27, R2-M124, and C5-M356; 81% combined) with a shared genetic heritage dating back to the late Pleistocene (10-30 Kya), suggesting that more recent Holocene migrations from western Eurasia contributed <20% of the male lineages. We found strong evidence for genetic structure, associated primarily with the current mode of subsistence. Coalescence analysis suggested that the social stratification was established 4-6 Kya and there was little admixture during the last 3 Kya, implying a minimal genetic impact of the Varna (caste) system from the historically-documented Brahmin migrations into the area. In contrast, the overall Y-chromosomal patterns, the time depth of population diversifications and the period of differentiation were best explained by the emergence of agricultural technology in South Asia. These results highlight the utility of detailed local genetic studies within India, without prior assumptions about the importance of Varna rank status for population grouping, to obtain new insights into the relative influences of past demographic events for the population structure of the whole of modern India.

The International Summer School on Vacuum, Electron and Ion Technologies (VEIT) has been organized biannually since 1977. It is a forum for the interchange and dissemination of knowledge and ideas on the latest developments in electron-, ion-, and plasma-assisted technologies. The organizers of the event (since 2001) have been the Institute of Electronics, Bulgarian Academy of Sciences, Sofia, Bulgaria, the Institute of Ion Beam Physics and Materials Research, Forschungszentrum Dresden-Rossendorf, Dresden, Germany, and the Evrika Foundation, Sofia, Bulgaria. The fifteenth meeting of VEIT was held in the Black Sea resort of Sozopol, Bulgaria from 17-21 September 2007 and was attended by around 120 participants from 17 countries: Australia, Belgium, Bulgaria, Canada, Czech Republic, Germany, Hungary, Italy, The Netherlands, Poland, Pakistan, Romania, Sweden, Switzerland, Ukraine, UK and USA. Following the tradition of publishing the VEIT Proceedings, a selection of papers presented at the event is published in this volume of Journal of Physics: Conference Series, all peer reviewed to meet the originality and quality criteria of the journal. The school consisted of 11 oral and 3 poster sessions. There were 17 invited talks of general interest and 12 progress reports were presented orally. In total 86 contributed papers were presented during the three poster sessions. There were several scientific highlights covering the fundamentals of gas discharges and interaction of fast particles with solids, a wide range of conventional and novel applications such as for hard coatings and optical/protective layers, nanosized structures produced by evaporation, sputtering or external irradiation. Recent achievements in the modification of materials using charged particles or laser beams, thin layers deposition, properties, and characterization and novel materials, techniques, devices were highlighted. Despite the busy scientific program, the atmosphere was relaxed and informal. The early afternoons of most conference days were free to stimulate both scientific and social interaction between participants, which often took place on the beach. The social program included a welcome reception, a conference banquet, and an outing to historical landmarks in the vicinity of Sozopol. VEIT 2007 owes its success to many people. The International Advisory Committee shaped the scientific program and ensured high-quality plenary presentations by careful selection of invited speakers. The Local Committee bore the brunt of the organization both at the conference site and in dealing with correspondence, abstracts, and manuscripts for these proceedings. We are grateful to our sponsors Forschungszentrum Dresden-Rossendorf, Dresden, Germany, Bulgarian Academy of Sciences, Sofia, Bulgaria, Hauser Techno Coating Ltd, Venlo, The Netherlands, and Evrika Foundation, Sofia, Bulgaria for their generosity that enabled us to support the attendance of students and provided support to deal with mailing, printing, renting the conference site, etc. We would like to also thank all authors for their valuable contributions to this proceeding and to the school, as well as all reviewers for their important work. The next conference in the series will be held in September 2009. Nikolay Guerassimov, Wolfhard Möller, Chavdar Ghelev Guest Editors

Set-up and validation of a Delft-FEWS based coastal hazard forecasting system

Valchev, Nikolay; Eftimova, Petya; Andreeva, Nataliya

2017-04-01

European coasts are increasingly threatened by hazards related to low-probability and high-impact hydro-meteorological events. Uncertainties in hazard prediction and capabilities to cope with their impact lie in both future storm pattern and increasing coastal development. Therefore, adaptation to future conditions requires a re-evaluation of coastal disaster risk reduction (DRR) strategies and introduction of a more efficient mix of prevention, mitigation and preparedness measures. The latter presumes that development of tools, which can manage the complex process of merging data and models and generate products on the current and expected hydro-and morpho-dynamic states of the coasts, such as forecasting system of flooding and erosion hazards at vulnerable coastal locations (hotspots), is of vital importance. Output of such system can be of an utmost value for coastal stakeholders and the entire coastal community. In response to these challenges, Delft-FEWS provides a state-of-the-art framework for implementation of such system with vast capabilities to trigger the early warning process. In addition, this framework is highly customizable to the specific requirements of any individual coastal hotspot. Since its release many Delft-FEWS based forecasting system related to inland flooding have been developed. However, limited number of coastal applications was implemented. In this paper, a set-up of Delft-FEWS based forecasting system for Varna Bay (Bulgaria) and a coastal hotspot, which includes a sandy beach and port infrastructure, is presented. It is implemented in the frame of RISC-KIT project (Resilience-Increasing Strategies for Coasts - toolKIT). The system output generated in hindcast mode is validated with available observations of surge levels, wave and morphodynamic parameters for a sequence of three short-duration and relatively weak storm events occurred during February 4-12, 2015. Generally, the models' performance is considered as very good and results obtained - quite promising for reliable prediction of both boundary conditions and coastal hazard and gives a good basis for estimation of onshore impact.

An exploratory investigation is reported into the role of spirituality and religious practice in protecting against depression among older people living in rural villages in Bulgaria and Romania, two neighbouring countries with similar cultural, political and religious histories, but with differing levels of current religiosity. In both countries, interviews were conducted with samples of 160 persons of 60 years and over in villages of similar socio-economic status. The Hospital Anxiety and Depression-D scale and the Royal Free Interview for Religious and Spiritual Beliefs were used to assess depression and spiritual belief and practice respectively. In addition social support, physical functioning and the presence of chronic diseases were assessed. One year later, follow-up interviews were conducted with 58 of the original sample in Bulgaria, in which additional measures of depression and of spiritual belief and practice were also included. The study demonstrates, as expected, significantly lower levels of spiritual belief in the Bulgarian sample (Bulgarian mean 29.7 (SD = 19.1), Romanian mean 47.6 (SD = 11.2), t = 10.2, p < 0.001), as well as significantly higher levels of depression (Bulgarian mean 12.0 (SD = 4.9), Romanian mean 7.3 (SD = 4.1), t = 9.3, p < 0.001), the latter attributable in large part to higher morbidity and disability rates, but less evidently to differences in strength of belief. However, analyses from both the cross-sectional study and the one-year follow-up of the Bulgarian sample do suggest that spiritual belief and practice may both influence and reflect physical and mental illness. Much of Eastern Europe displays high rates of depression among its older population and provides opportunities for investigation of the role of religious belief and practice in preventing and coping with depression. Further research is encouraged in populations of diverse religiosity.

The paper deals with application of different statistical methods like cluster and principal components analysis (PCA), partial least squares (PLSs) modeling. These approaches are an efficient tool in achieving better understanding about the contamination of two gulf regions in Black Sea. As objects of the study, a collection of marine sediment samples from Varna and Bourgas "hot spots" gulf areas are used. In the present case the use of cluster and PCA make it possible to separate three zones of the marine environment with different levels of pollution by interpretation of the sediment analysis (Bourgas gulf, Varna gulf and lake buffer zone). Further, the extraction of four latent factors offers a specific interpretation of the possible pollution sources and separates natural from anthropogenic factors, the latter originating from contamination by chemical, oil refinery and steel-work enterprises. Finally, the PLSs modeling gives a better opportunity in predicting contaminant concentration on tracer (or tracers) element as compared to the one-dimensional approach of the baseline models. The results of the study are important not only in local aspect as they allow quick response in finding solutions and decision making but also in broader sense as a useful environmetrical methodology.

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 and storage. Specialized software for elaboration of scenarios of seismic hazard is designed and implemented. The reaction of buildings, roads, bridges, land etc. to earthquakes is graphically shown on the monitor. The high risk areas are highlighted in order for the emergency units to be prepared for intervention. This software is designed on the base of a comprehensive relational data base of historical and contemporary seismicity in the cross-border region. The output shake maps and scenarios are to be used by the emergency intervention units, local public authorities and for general public awareness.

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.

Ladies and Gentlemen Dear Friends and Colleagues I welcome you at the 5th International Symposium `Quantum Theory and Symmetries, QTS5' in Valladolid as Chairman of the Conference Board of this biannual series. The aim of the series is to arrange an international meeting place for scientists working in theoretical and mathematical physics, in mathematics, in mathematical biology and chemistry and in other sciences for the presentation and discussion of recent developments in connection with quantum physics and chemistry, material science and related further fields, like life sciences and engineering, which are based on mathematical methods which can be applied to model and to understand microphysical and other systems through inherent symmetries in their widest sense. These systems include, e.g., foundations and extensions of quantum theory; quantum probability; quantum optics and quantum information; the description of nonrelativistic, finite dimensional and chaotic systems; quantum field theory, particle physics, string theory and quantum gravity. Symmetries in their widest sense describe properties of a system which could be modelled, e.g., through geometry, group theory, topology, algebras, differential geometry, noncommutative geometry, functional analysis and approximation methods; numerical evaluation techniques are necessary to connect such symmetries with experimental results. If you ask for a more detailed characterisation of this notion a hand waving indirect answer is: Collect titles and contents of the contributions of the proceedings of QTS4 and get a characterisation through semantic closure. Quantum theory and its Symmetries was and is a diversified and rapidly growing field. The number of and the types of systems with an internal symmetry and the corresponding mathematical models develop fast. This is reflected in the content of the five former international symposia of this series: The first symposium, QTS1-1999, was organized in Goslar (Germany) with 170 participants and 89 contributions in the proceedings; it was centred on the foundations and extensions of quantum theory, on quantisation methods and on q-algebras. In QTS2-2001 in Cracow (Poland) with 175 participants and 81 contributions; the main topics were applications of quantum mechanics, representations of algebras and group theoretical techniques in physics. In the symposium QTS3-2003 in Cincinnati (USA) with 145 participants and 92 contributions, quantum field theory, loop quantum gravity, string and brane theory was discussed. The focus in QTS4-2005 in Varna (Bulgaria) with 228 participant and 105 contributions, was on conformal field theory, quantum gravity, noncommutative geometry and quantum groups. Three proceedings volumes were published with World Scientific and one volume with Heron Press. The promising and interesting programme for QTS5-2007 in Valladolid (Spain) attracted more than 200 participants; the contributions will be published in a special issue of Journal of Physics A: Mathematical and Theoretical and a volume of Journal of Physics: Conference Series. This shows the wide scope of symmetry in connection with quantum physics and related sciences. In the background of the symposia series is the Conference Board with presently 13 members. The Board encourages scientists and Institutions to present detailed proposals for a QTS symposium; it agrees to one proposal and is prepared to assist in matters of organisation; the local organisers are responsible for the scientific programme and for the organisation, including the budget. The Board decided that the next symposium QTS6 will be held 2009 at the University of Kentucky in Lexington (USA); Alan Shapere is the chairman of the Local Organizing committee. In the name of all of you I express my appreciation and my thanks to the members of the Local Organizing Committee of QTS5, especially to Mariano del Olmo. The programme is outstanding; it covers recent and new developments in our field. The organization is very effective and complete. We have all the necessary condition for a successful and smooth meeting. Thank you again Mariano. H-D Doebner Chairman of the Conference Board of QTS5

To assess to what extent eight behavioural health risks related to breakfast and food consumption and five behavioural health risks related to physical activity, screen time and sleep duration are present among schoolchildren, and to examine whether health-risk behaviours are associated with obesity. Cross-sectional design as part of the WHO European Childhood Obesity Surveillance Initiative (school year 2007/2008). Children's behavioural data were reported by their parents and children's weight and height measured by trained fieldworkers. Descriptive statistics and logistic regression analyses were performed. Primary schools in Bulgaria, Lithuania, Portugal and Sweden; paediatric clinics in the Czech Republic. Nationally representative samples of 6-9-year-olds (n 15 643). All thirteen risk behaviours differed statistically significantly across countries. Highest prevalence estimates of risk behaviours were observed in Bulgaria and lowest in Sweden. Not having breakfast daily and spending screen time ≥2 h/d were clearly positively associated with obesity. The same was true for eating 'foods like pizza, French fries, hamburgers, sausages or meat pies' >3 d/week and playing outside <1 h/d. Surprisingly, other individual unhealthy eating or less favourable physical activity behaviours showed either no or significant negative associations with obesity. A combination of multiple less favourable physical activity behaviours showed positive associations with obesity, whereas multiple unhealthy eating behaviours combined did not lead to higher odds of obesity. Despite a categorization based on international health recommendations, individual associations of the thirteen health-risk behaviours with obesity were not consistent, whereas presence of multiple physical activity-related risk behaviours was clearly associated with higher odds of obesity.

Terrorism in Bulgaria.

PubMed

Shanduorkov, George

2003-01-01

The Republic of Bulgaria is one of the smallest countries in southeastern Europe and has little experience with terrorist acts. During the past 20 years, only nine terrorism-related events have been recorded in Bulgaria, and no unconventional weapons have been used. Factors contributing to terrorism in Bulgaria have been: (1) Communist Party domination of the government and political process from 1944 to 1989; (2) ethnic and religious conflicts between the Bulgarian Orthodox Christian majority and the Turkish Muslim minority from 1983 to 1987; and (3) the relatively high level of organized crime after the Communist regime ended in 1990. The structure and function of the Disaster Relief System in Bulgaria not only are focused on the prevention of terrorism, but also on preparedness for the emergency response to terrorism-related events. Institutional components of the Disaster Relief System structure responsible for the emergency response to terrorism-related events include: (1) the Government of Bulgaria; (2) the State Agency for Civil Protection with 28 regional directorates; (3) the Ministry of Health with five national hospitals, 28 regional hospitals, and 28 EMS systems; (4) the Ministry of Defense with special military units for response to unconventional terrorist events, including nuclear, biological, and chemical weapons; (5) the Ministry of Internal Affairs with 28 police departments, 28 fire departments, and specialized anti-terrorist units; and (6) the Bulgarian Red Cross. A major future challenge in Bulgaria is the prevention of terrorism through political stability, economic prosperity, ethnic and religious tolerance, and more effective measures against organized criminal activities. A related challenge will be to improve the level of preparedness of all components of Disaster Relief.

Coastal flooding hazard assessment on potentially vulnerable coastal sectors at Varna regional coast

Storm induced flooding is one of the most significant threats that the coastal communities face. In the light of the climate change it is expected to gain even more importance. Therefore, the adequate assessment of this hazard could increase the capability of mitigation of environmental, social, and economic impacts. The study was accomplished in the frames of the Coastal Risk Assessment Framework (CRAF) developed within the FP7 RISC-KIT Project (Resilience-Increasing Strategies for Coasts - toolkit). The hazard assessment was applied on three potentially vulnerable coastal sectors located at the regional coast of Varna, Bulgarian Black Sea coast. The potential "hotspot" candidates were selected during the initial phase of CRAF which evaluated the coastal risks at regional level. The area of interest comprises different coastal types - from natural beaches and rocky cliffs to man modified environments presented by coastal and port defense structures such as the Varna Port breakwater, groynes, jetties and beaches formed by the presence of coastal structures. The assessment of coastal flooding was done using combination of models -XBeach model and LISFLOOD inundation model applied consecutively. The XBeach model was employed to calculate the hazard intensities at the coast up to the berm crest, while LISFLOOD model was used to calculate the intensity and extent of flooding in the hinterland. At the first stage, 75 extreme storm events were simulated using XBeach model run in "non-hydrostatic" mode to obtain series of flood depth, depth-velocity and overtopping discharges at the predefined coastal cross-shore transects. Extreme value analysis was applied to the calculated hazard parameters series in order to determine their probability distribution functions. This is so called response approach, which is focused on the onshore impact rather than on the deep water boundary conditions. It allows calculation of the hazard extremes probability distribution induced by a variety of combinations of waves and surges. The considered return periods were 20, 50 and 100 years. Subsequently, the overtopping volumes corresponding to preferred return periods were fed into LISFLOOD model to calculate the intensity and extent of the hinterland flooding. For the beaches with fast-rising slopes backed by cliffs a combination of XBeach and LISFLOOD output was applied in order to properly map the flood depth and depth-velocity spatial distribution.

There is a lot of research proving the positive influence of humic substances on the development of plants in combination with soil isolates such as Pseudomonas and Bacillus. Humic substances obtained by chemical extraction and biosolubilization of various sources of organic materials were tested for their effect on the growth of Poinsettia (Euphorbia pulcherrima) cultivar „Mirat red". The test included the following variants: 1. Humic substances chemically extracted from "Humintech" leonardite (Ht); 2. Humic substances obtained from "Humintech" leonardite by biosolubilization with Pseudomonas putida (Pp) and Bacillus pasteurii (Bp) (Ht Bp Pp); 3. Humic substances chemically extracted from "Sachalin" leonardite; 4. Humic substances obtained from "Sachalin" leonardite by biosolubilization with Pseudomonas putida (Pp) and Bacillus pasteurii (Bp) (Sachalin Bp Pp); 5. Fulvic substances exracted after biosolubilization of "Staniantsy" lignite with Pseudomonas putida (Pp) and Bacillus pasteurii (Bp) (FB Plantagra); 6. Humic substances exracted after biosolubilization of "Staniantsy" lignite with Pseudomonas putida (Pp) and Bacillus pasteurii (Bp) (Lignohumate); 7. Biohumax - commercial product of "Project Studio" EOOD, Varna Bulgaria; 8.Vermicompost inoculated with Pseudomonas putida and Bacillus pasteurii (Strong BG); 9. Control - Nutrient solution (background of nutrition). The test results indicate that as a result of microbial activity active bacterial compounds are probably present in the composition of the extracted humates, thus affecting the formation of red leaves.The application of all tested substances results in red leaves area increase of treated plants compared to the control plants, except the humates chemically extracted from Humintech leonardite. The ration between humic and fulvic acids determines the effect on the treated plants. The biosolubilized preparations contain more fulvic acids. Plants treated with them form up to three times more anthocyanins compared to the control plants. The results from the experiment show that humic substances, being biologically active, are capable of regulating the growth of microorganisms. A combination of bacterial and humic compositions applied to poinsettia plants has a positive effect on their development. Obviously the biosolubilization of leonardite and other organic materials to humic substances is more promising than the chemical one

The Second International Workshop & Summer School on Plasma Physics (IWSSPP'06) organized by St. Kliment Ohridsky University of Sofia, The Union of the Physicists in Bulgaria, the Bulgarian Academy of Sciences and the Bulgarian Nuclear Society, was held in Kiten, Bulgaria, on the Black Sea Coast, from 3-9 July 2006. As with the first of these scientific meetings (IWSSPP'05 Journal of Physics: Conference Series 44 (2006)), its aim was to stimulate the creation and support of a new generation of young scientists for further development of plasma physics fundamentals and applications, as well as to ensure an interdisciplinary exchange of views and initiate possible collaborations by bringing together scientists from various branches of plasma physics. This volume of Journal of Physics: Conference Series includes 33 papers (invited lectures, contributed talks and posters) devoted to various branches of plasma physics, among them fusion plasma research, dc and microwave discharge modelling, transport phenomena in gas discharge plasmas, plasma diagnostics, cross sections and rate constants of elementary processes, material processing, plasma-chemistry and technology. Some of these papers were presented by internationally known and recognized specialists in their fields; others are MSc or PhD students' first steps in science. In both cases, we believe they will raise readers' interest. We would like to thank the members of both the International Advisory Committee and the Local Organizing Committee, the participants who sent their manuscripts and passed through the (sometimes heavy and troublesome) refereeing and editing procedure and our referees for their patience and considerable effort to improve the manuscripts. We greatly appreciate the financial support from the sponsors: the Department for Language Teaching and International Students at the University of Sofia and Natsionalna Elektricheska Kompania EAD. We would like to express our gratitude to the invited lecturers who were willing to pay the participation fee. In this way, in addition to the intellectual support they provided by means of their excellent lectures, they also supported the school financially.

Change in tobacco excise policy in Bulgaria: the role of tobacco industry lobbying and smuggling.

To examine how transnational tobacco companies (TTCs) tried to penetrate the Bulgarian cigarette market and influence tobacco excise tax policy after the fall of communism and during Bulgaria's accession to the European Union (EU). Analysis of internal tobacco industry documents supplemented by analysis of press coverage, tobacco industry journals, market reports and key informant interviews. TTCs have been involved in cigarette smuggling to and through Bulgaria since at least 1975 and used smuggling as a market-entry strategy. National tobacco company Bulgartabac appears to have been involved in smuggling its own cigarettes from and reimporting them to Bulgaria. Since Bulgaria's accession to the EU opened the market to the TTCs, TTCs have exaggerated the scale of the illicit trade to successfully convince politicians and public health experts that tax increases lead to cigarette smuggling. Yet, sources point to TTCs' continued complicity in cigarette smuggling to and through Bulgaria between 2000 and 2010. TTCs aimed to influence the Bulgarian tobacco excise tax regime, import duties and pricing mechanism, but appear to have been less successful than in other former communist countries in part due to the co-existence of a state-owned tobacco company. Undisclosed meetings between the tobacco industry and government ministers and officials are ongoing despite Bulgaria being a party to the Framework Convention on Tobacco Control (FCTC). The TTCs continued involvement in smuggling suggests that deals in 2004, 2007 and 2010 which the European Commission has reached with TTCs to address cigarette smuggling are inadequate. The TTCs' continued access to policymakers suggests that the FCTC is not being properly implemented. Published by the BMJ Publishing Group Limited.

Crimean-Congo hemorrhagic fever (CCHF) and hantavirus infections are the two viral hemorrhagic fevers spread in Europe. To test actual circulation of CCHF virus (CCHFV) and hantaviruses in Bulgaria, we conducted country-wide seroepidemiological studies. Serum samples were collected prospectively from 1500 residents of all 28 districts in Bulgaria. CCHFV seroprevalence of 3.7% was revealed. Anamnesis for tick bites, contact with livestock, age over 40 years and residency in Haskovo district were found as risk factors. The highest CCHFV seroprevalence was observed in the known endemic districts in southeastern Bulgaria: Haskovo (28%) and Yambol (12%). Reactive samples were found in residents of 20 of the 28 districts in Bulgaria. In comparison with the previous studies, the data presented indicate that CCHFV increased substantially its circulation in the endemic regions and was introduced in many new areas. Hantavirus seroprevalence was based on results of the immunoblot and estimated as 3.1%. Surprisingly, contrary to all available data, Puumala virus seroprevalence rate was 2.3% versus 0.8% of Dobrava-Belgrade virus. Evidence for hantavirus IgG seropositivity was found in residents of 23 of the 28 districts in the country. The first hantavirus seroprevalence study in Bulgaria showed that Puumala virus is probably more wide-spread in the country than Dobrava-Belgrade virus. © 2017 Wiley Periodicals, Inc.

This special issue of Journal of Physics A: Mathematical and Theoretical appears on the occasion of the 5th International Symposium on Quantum Theory and Symmetries (QTS5), held in Valladolid, Spain, from 22-28 July 2007. This is the fith in a series of conferences previously held in Goslar (Germany) 1999, QTS1; Cracow (Poland) 2001, QTS2; Cincinnati (USA) 2003, QTS3; and Varna (Bulgaria) 2005, QTS4. The QTS5 symposium gathered 181 participants from 39 countries working in different fields of theoretical physics. The spirit of the QTS conference series is to join researchers in a wide variety of topics in theoretical physics, as a way of making accessible recent results and the new lines of different fields. This is based on the feeling that it is good for a physicist to have a general overview as well as expertise in his/her own field. There are many other conferences devoted to specific topics, which are of interest to gain deeper insight in many technical aspects and that are quite suitable for discussions due to their small size. However, we believe that general conferences like this are interesting and worth keeping. We like the talks, in both plenary and parallel sessions, which are devoted to specific topics, to be prepared so as to be accessible to any researcher in any branch of theoretical physics. We think that this objective is compatible with rigour and high standards. As is well known, similar methods and techniques can be useful for many problems in different fields. We hope that this has been appreciated during the sessions of the QTS5 conference. The QTS5 conference offered the following list of topics: 1. Symmetries in string theory, quantum gravity and related topics 2. Symmetries in quantum field theories, conformal and related field theories, lattice and noncommutative theories, gauge theories 3.Quantum computing, information and control 4. Foundations of quantum theory 5. Quantum optics, coherent states, Wigner functions 6. Dynamical and integrable systems 7. Symmetries in condensed matter and statistical physics 8. Symmetries in particle physics, nuclear, atomic and molecular physics 9. Nonlinear quantum mechanics 10. Time asymmetric quantum mechanics 11. SUSY quantum mechanics, PT symmetries and pseudo-Hamiltonians 12. Mathematical methods for symmetries and quantum theories 13. Symmetries in chemistry, biology and other sciences Papers accepted for publication in this issue aim to provide a survey of the state of the art in different fields and contain contributions from plenary speakers. In addition, the issue contains contributions from other participants and it has also been open to other authors whose work fits into the topics of the conference. In any case, all the contributions have been refereed according to the high standards of Journal of Physics A: Mathematical and Theoretical. We are much indebted to several institutions; without their support the organization of the QTS5 symposium would not have been possible. In this respect we acknowledge the Ministerio de Educación of Spain and Junta de Castilla y León for general financial support; to Fundación Universidades de Castilla y León for a number of grants to young researchers who otherwise would not have attended the conference; also to the European Physical Society that provided a number of grants for eastern countries, and to the University of Valladolid where the event took place. We thank IOP Publishing and the staff of Journal of Physics A: Mathematical and Theoretical for the publication of this special issue. In addition, we want to express our gratitude to other members of the Local Organizing Committe of QTS5, who are not Editors of this special issue: Oscar Arratia, Juan A Calzada and Fernando Gómez. Finally, we would like to thank all the participants in the QTS5 conference for their presence, contributions, and for the good atmosphere achieved during their stay. We hope that the experience of spending these days in Valladolid has been most fruitful for all of them.

We are pleased to introduce the Proceedings of the 16 ISCMP, organized by the Institute of Solid State Physics of the Bulgarian Academy of Sciences. The Chairman of the School was Professor Alexander G Petrov. The School was dedicated to the late Professor Joe Marshall, who served for a long time as Chairman and Honorary Chairman and left us just after having completed the proceedings of the previous School. Like previous events, the School took place in the beautiful Black Sea resort of Saint Constantine and Elena near Varna, going back to the renewed facilities of the Panorama hotel. Participants from 19 different countries delivered 34 invited lecturers and 75 posters, contributing to three sessions of poster presentations. Papers submitted to the Proceedings were refereed according to the high standards of the Journal of Physics: Conference Series and the articles published in this volume illustrate the diversity and the high level of the contributions. Not the least significant factor in the success of the 16 ISCMP was the social program, both the organized events (Welcome and Farewell Parties) and the variety of pleasant local restaurants and beaches. These Proceedings are published for the first time in Journal of Physics: Conference Series. We are grateful to the Journal's staff for encouraging this idea. The Scientific Committee of the ISCMP dedicates this volume of the Proceedings to the living memory of Professor Joe Marshall, Honorary Chairman of the ISCMP. The Committee decided that the next event will take place again in Saint Constantine and Elena, in September 2012. It will be entitled: Open Problems in Condensed Matter Physics, Biomedical Physics and their Applications. Doriana Dimova-Malinovska, Diana Nesheva, Alexander G Petrov and Marina T Primatarowa

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. © 2015 Wiley Periodicals, Inc.

Anomalies of hydrological cycle components during the 2007 heat wave in Bulgaria

Heat waves have large adverse social, economic and environmental effects which include increased mortality, transport restrictions and a decreased agricultural production. The estimated economic losses of the 2007 heat wave in South-east Europe exceed 2 billion EUR with 19 000 hospitalisation in Romania only. Understanding the changes of the hydrological cycle components is essential for early forecasting of heat wave occurrence. Valuable insight of two components of the hydrological cycle, namely Integrated Water Vapour (IWV) and Terrestrial Water Storage Anomaly (TWSA), is now possible using observations from Global Navigation Satellite System (GNSS) and Gravity Recovery And Climate Experiment (GRACE) mission. In this study anomalies of temperature, precipitation, IWV and TWS in 2007 are compared to 2003-2013 period for Sofia, Bulgaria. In 2007, positive temperature anomalies are observed in January, February and July. There are negative IWV and precipitation anomalies in July 2007 that coincides with the heat wave in Bulgaria. TWSA in 2007 are negative in January, May and from July to October being largest in August. Long-term trends of: 1) temperatures have a local maximum in March 2007, 2) TWSA has a local minimum in May 2007, 3) IWV has a local minimum in September 2007, and 4) precipitation has a local maximum in July 2007. The TWSA interannual trends in Bulgaria, Hungary and Poland show similar behaviour as indicated by cross correlation coefficients of 0.9 and 0.7 between Bulgaria and Hungary and Bulgaria and Poland respectively. ALADIN-Climate describes the anomalies of temperature and IWV more successfully than those of precipitation and TWS.

Politics and abortion in Bulgaria.

PubMed

Sirakova, K

1992-01-01

Political change in Bulgaria has meant the beginning of the recognition of the reproduction rights of women. Abortion, for example, was legalized in 1990. Women in Bulgaria, however, still lack the information they need on basic hygiene and sex. It is impossible to promulgate a progressive strategy in Bulgaria if one ignores the isolation of the Turkish and Gypsy ethnic communities. In addition, an economic crisis exists, and no real measures have been undertaken to mitigate the situation. The new democratic institutions have settled comfortably into the structures of the former communist rule, even to the point of adopting the same extensive demagogic terminology which perpetrates the old gap between words and deeds. For example, although a new birth control strategy and plan for sex education was announced 2 years ago, nothing definite has been done. One development, however, has been the legalization of abortion, which was accompanied by an immediate drop in the abortion rate (still 1.5 abortions/birth). Because of a lack of sex education, 900 children are born to girls under age 15 each year. Bulgaria is just starting to embrace modern values and must update its attitudes towards women. Bulgaria's formal institutions seem to be unable to face this issue, and many societies and foundations have emerged to work for women's rights, to protect out-of-wedlock children, and to fight disease (including AIDS) and drug addiction. However, these organizations are not producing real results and are simply providing shelter to representatives of the old nomenclature. Real efforts to overcome these problems will continue despite the current discouraging state of affairs.

Development of Bioethics and Clinical Ethics in Bulgaria.

Aleksandrova-Yankulovska, Silviya S

2017-03-01

Bioethics and clinical ethics emerged from the classical medical ethics in the 1970s of the 20th century. Both fields are new for the Bulgarian academic tradition. The aims of this paper were to demarcate the subject fields of medical ethics, bioethics, and clinical ethics, to present the developments in the field of medical ethics in Bulgaria, to delineate the obstacles to effective ethics education of medical professionals, and to present the results of the application of an adapted bottom-up methodology for clinical ethics consultation in several clinical units in Bulgaria. Extended literature review and application of an adapted METAP methodology for clinical ethics consultation in six clinical units in the Northern Bulgaria between May 2013 and December 2014. Teaching of medical ethics in Bulgaria was introduced in the 1990s and still stands mainly as theoretical expertise without sufficient dilemma training in clinical settings. Earlier studies revealed need of clinical ethics consultation services in our country. METAP methodology was applied in 69 ethics meetings. In 31.9% of them non-medical considerations affected the choice of treatment and 34.8% resulted in reaching consensus between the team and the patient. Participants' opinion about the meetings was highly positive with 87.7% overall satisfaction. Development of bioethics in Bulgaria follows recent worldwide trends. Several ideas could be applied towards increasing the effectiveness of ethics education. Results of the ethics meetings lead to the conclusion that it is a successful and well accepted approach for clinical ethics consultation with a potential for wider introduction in our medical practice.

Gender impact on the socioprofessional identification of women dentists in Bulgaria.

PubMed

Katrova, Lydia G

2004-07-01

Women comprise 73 percent of all dentists in Bulgaria. Almost all of them started their careers as salaried, and now they are self-employed. The purpose of this study was to show how female dentists in Bulgaria met the challenges of the social and health reforms during the period of transition from totalitarian to democratic rule. A field sociological survey was carried out between October 1996 and June 1997, involving a sample of 842 dentists. The questionnaire was designed to give information on dental demography trends, pattern of participation and practice of female dentists, and their career development. The data were treated statistically using an SPSS package. Results show that for the period 1991-96 women dentists owned more than 50 percent of the newly opened private practices in Bulgaria. They were more interested in improving their qualifications and more successful in obtaining specialty status than male dentists. Dentists in Bulgaria by the late 1990 s, with no gender difference, tend to identify themselves as liberal practitioners within the pluralistic model of dental services delivery. The volume of services delivered and profile of women in professional practice and their social and professional mobility are highly competitive, despite the growing problems of maternity leave coverage and funding to re-enter the profession.

Seismic Hazard and risk assessment for Romania -Bulgaria cross-border region

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 parameter in the historical earthquake catalogues. A particular advantage of using intensities is that the very irregular pattern of the attenuation field of the Vrancea intermediate depth earthquakes can be estimated from detailed macroseismic observations that are available (in both countries) for the study region. Additionally, de-aggregation of the seismic hazard for a recurrence period of 475 years (probability of exceedance of 10% in 50 years) for intensity was performed for 9 cities (administrative centers) situated in northern Bulgaria. Finally, applying SELENA software earthquake risk for Bulgarian part of the cross-boarder region is analyzed. The results presented for the Romania-Bulgaria cross border region are part of the work carried out in the DACEA Project (2010-2013) that was implemented in the framework of the Romania - Bulgaria Cross Border Cooperation Programme (2007-2013).

Fourth International Workshop & Summer School on Plasma Physics 2010 The Fourth International Workshop & Summer School on Plasma Physics (IWSSPP'10) is organized by St. Kliment Ohridsky University of Sofia, with co-organizers TCPA Foundation, Association EURATOM/IRNRE, The Union of the Physicists in Bulgaria, and the Bulgarian Academy of Sciences. It was held in Kiten, Bulgaria, at the Black Sea Coast, from July 5 to July 10, 2010. The scientific programme covers the topics Fusion Plasma and Materials; Plasma Modeling and Fundamentals; Plasma Sources, Diagnostics and Technology. As the previous issues of this scientific meeting (IWSSPP'05, J. Phys.: Conf. Series 44 (2006) and IWSSPP'06, J. Phys.: Conf. Series 63 (2007), IWSSPP'08, J. Phys.: Conf. Series 207 (2010), its aim was to stimulate the creation and support of a new generation of young scientists for further development of plasma physics fundamentals and applications, as well as to ensure an interdisciplinary exchange of views and initiate possible collaborations by bringing together scientists from various branches of plasma physics. This volume of Journal of Physics: Conference Series includes 34 papers (invited lectures, contributed talks and posters) devoted to various branches of plasma physics, among them fusion plasma and materials, dc and microwave discharge modelling, transport phenomena in gas discharge plasmas, plasma diagnostics, cross sections and rate constants of elementary processes, material processing, plasma-chemistry and technology. Some of them have been presented by internationally known and recognized specialists in their fields; others are MSc or PhD students' first steps in science. In both cases, we believe they will raise readers' interest. We would like to thank the members of both the International Advisory Committee and the Local Organizing Committee, the participants who sent their manuscripts and passed through the (sometimes heavy and troublesome) refereeing and editing procedure and our referees for their patience and considerable effort to improve the manuscripts. We would like to express our gratitude to the invited lecturers who were willing to pay the participation fee. In this way, in addition to the intellectual support they provided by means of their excellent lectures, they also supported the school financially. E. Benova

Increased HIV transmission in persons who inject drugs (PWIDs) has led to subepidemics and outbreaks in several countries in Europe, including Bulgaria. In this study in Bulgaria, we investigate the origin and spatiotemporal evolutionary history of HIV-1 infections in PWIDs and the distribution of antiretroviral resistance mutations and hepatitis co-infections in these populations. We analyzed HIV-1 polymerase sequences available from 117 of 359 PWIDs diagnosed with HIV/AIDS from 1999 to 2011. Of these, 50 (42.7%) were classified as CRF02_AG, 41 (35.0%) CRF01_AE, 12 (10.3%) URFs, ten (8.5%) subtype B, two (1.7%) subtype F1 and two (1.7%) CRF14_BG. Most recent common ancestor dating suggests that CRF01_AE was likely first introduced from Southeast Asia into persons reporting heterosexual infection in Bulgaria in 1992 and spread subsequently to PWIDs in the capital city of Sofia around 2003. Conversely, CRF02_AG in Bulgaria was likely first introduced into PWID from Germany in 2000 and later entered heterosexual populations around 2009. The overall prevalence of resistance mutations was 6.8% (8/117), of which 5.1% (5/117) was observed in patients on antiretroviral therapy and 1.7% (2/117) was from transmitted drug resistance mutations in drug-naïve individuals. 189/204 (92.6%) PWIDs were also co-infected with hepatitis C (HCV) and 31/183 (16.9%) were co-infected with hepatitis B (HBV). Our study provides valuable molecular epidemiological information on the introduction and distribution of the main HIV-1 subtypes, resistance mutations and hepatitis co-infections among PWIDs with HIV-1 in Bulgaria which can be used to target prevention efforts.

2017-10-01

The city of Ruse is situated in the north-eastern part of Bulgaria. The northern boundary of Ruse region goes along the Danube river valley and coincides with the state boundary of the Republic of Bulgaria and the Republic of Romania. The climate of the region of Ruse is temperate continental, characterized by cold winters and dry, warm summers. Spring and autumn are short. In our previous work we studied information from 40 years period measurements [6] of temperature, air humidity and atmospheric pressure in Ruse region, Bulgaria. It was shown that mean values of the temperature in Ruse region are slightly goes up for the last 10 years and they are bigger than the mean temperature for Bulgaria. This could be a proof for climate change in Ruse region of Bulgaria. 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 [5]. Air pollution maybe affects temperature, atmospheric pressure and humidity. All this in our opinion may be a reason for the increase in average temperatures for the period examined. This paper is devoted to examine air pollution in the Ruse region. It presents a statistical analysis of the level of air pollution in Ruse on data from the monitoring stations in the city. The measurements cover the period from 2015 including up to now. For the most dangerous pollutant PM10 we create an ARIMA model which is in a good agreement with the PM10 measurements.

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

PRICING, REIMBURSEMENT, AND HEALTH TECHNOLOGY ASSESSMENT OF MEDICINAL PRODUCTS IN BULGARIA.

PubMed

2017-01-01

The aim of this study was to investigate the analysis, discussion, and challenges of the price and reimbursement process of medicinal products in Bulgaria in the period 2000-15 and health technology assessment (HTA) role in these processes. The dynamics of the reform, with respect to the healthcare and pharmaceutical sectors, are tracked by documentary review of regulations, articles, and reports in the European Union (EU), as well as analytical and historical analysis. Pricing and reimbursement processes have passed through a variety of committees between 2003 and 2012. Separate units for pricing and reimbursement of medicinal products were established in Bulgaria for the first time, in 2013, when an independent body, the National Council at Prices and Reimbursement of Medicinal Products, was set up to approve medicinal products with new international nonproprietary names (INN) for reimbursement in Bulgaria. Over the course of 2 years (2013-14), thirty-three new INNs were approved for reimbursement. In December 2015, a new HTA body was introduced, and assigned to the National Centre for Public Health and Analyses. Although Bulgaria has current legislation on pricing and reimbursement which is in accordance with the EU rules, there is no mechanism for reporting and monitoring these processes or the financial resources annually, so as to provide an overall objective assessment and analysis by year. Therefore, this financial assessment should become a national policy objective for the future.

Is anybody doing it? An experimental study of the effect of normative messages on intention to do physical activity.

van Bavel, René; Esposito, Gabriele; Baranowski, Tom

2014-07-31

The study explores whether messages about the physical activity levels of the majority (i.e. normative messages) affect young adults' intention to engage in regular physical activity. An experimental survey among 16 to 24 year-olds in Bulgaria, Croatia and Romania (n = 1200) was conducted in March 2013. A control group received no message; one treatment group was told that the majority was physically active (positive message); and another treatment group was told that the majority was not physically active (negative message). Both the positive and (unexpectedly) the negative normative messages showed a significant and positive effect on intention to be physically active. There was no difference between the effects of the messages. Normative messages affect intention, which is encouraging for public health campaigns. The effect of the positive message confirms previous findings on conformity to the norm; the effect of the negative message is unexpected and requires further research to be understood.

The Balkan Cities Association of Nephrology, Dialysis, Transplantation and Artificial Organs (BANTAO) was born in Ohrid on October 9, 1993. The war in former Yugoslavia negatively affected the development of nephrology and also the connections among the nephrologists from the Balkans. However, there was willingness for further mutual collaboration between the nephrologists from the Balkans. The war in Yugoslavia created hate among people, between the newly established countries, and there were problems with the recognition of the names of the new countries, and so, the nephrologists decided to apply the ancient principle of using the names of the cities, instead of the countries, as the founders of the Association. The main goal of BANTAO is to promote scientific and technical cooperation in the fields of renal disease and artificial organs between the regions on the Balkan Peninsula and the world, to give an opportunity for exchange of experience and knowledge among the experts in the area and to engage in collaborative projects in order to demonstrate that cooperation is possible even on the turbulent Balkan Peninsula. The I BANTAO congress was held in Varna from September 22 to 24th, 1995 (President--D. Nenov, Varna). The II congress of BANTAO was held from September 6th to 10th, 1997 in Struga, (President--M. Polenakovic, Skopje). The III BANTAO congress was held in Belgrade from September 18th to 20th, 1998 (President--Lj. Djukanović, Belgrade). The IV congress of BANTAO was held in Izmir from 14th to 16th November 1999 (President--A. Akcicek, Izmir). The V Congress of BANTAO was held in Thessaloniki from September 30th to October 3rd, 2001 (President--P. Stathakis, Athens). The VI Congress of BANTAO was held for the second time in Varna from 6th to 9th October 2003 (President--D. Nenov, Varna). The VII congress of BANTAO was held from September 8th to 11th, 2005 in Ohrid, (President--M. Polenakovic, Skopje). The VIII BANTAO congress was held in Belgrade, 16-19 September 2007 (President--V. Nesic, Belgrade). The IX BANTAO congress was held in Antalya, 18-22 November 2009 (President--A. Basci, Izmir). The X BANTAO congress was held from 13 to 15 October 2011 in Chalkidiki (President--D. Tsakiris, Thessaloniki). The XI BANTAO congress is being held on 26-29 September 2013 in Timisoara (President--A. Schiller, Timisoara). At the VII BANTAO Congress for the first time a CME Course was organized by ERA/EDTA and ISN/COMGAN entitled "Frontiers in Nephrology" with seven distinguished speakers. Very important event in the existence of BANTAO is the appearance of the BANTAO journal in 2003. The BANTAO journal has been published biannually since 2003. In the past 10 years, 20 regular issues; 2 supplements (Antalia and Chalkidiki congresses) have been published. Editors of the journal were as follows: 2003-2005--D. Nenov, Editor; 2005-2009--A. Basci, Editor; 2009--Goce Spasovski, Editor. Until now 332 papers have been published. The BANTAO journal is on EBSCO, DOAJ, SCOPUS. After the First Congress of BANTAO, F. Valderrábano, chairman of the EDTA--ERA Registry, at that time, wrote in Nephrology Dialysis Transplantation (1996) 11:740: "Nephrologists of the Balkan countries meet across political frontiers and war fronts--an example to politicians! a new European Medical Association overcomes Political obstacles." Despite the difficulties imposed by major events, such as devastating wars and catastrophic earthquakes in many countries of the Balkan Peninsula BANTAO has made considerable progress. The BANTAO Congress was established as the major scientific and institutional forum for Balkan nephrologists, with its own journal, indicating our will to communicate, to collaborate, to get to know each other and to share our difficulties. Now, we expect further successful work of BANTAO.

To analyse the incidence and mortality of some malignant diseases among the population living in regions of past uranium extraction in Bulgaria. A retrospective study on cancer incidence and mortality in the population living around two regions with radioecological problems was conducted. According to the expected individual annual effective doses for the population, regions with expected highest radiation risk (average effective dose > 10 mSv per year) were the villages Yana, Eleshnitza and Seslavtzi (group A), and with expected relatively high radiation risk (average effective dose > 5 mSv per year) were the town of Buhovo, and the villages Dolni Bogrov and Gorni Bogrov (group B). The ecologically clean village German was chosen as a control settlement. The incidence and mortality of gastrointestinal tract cancers, bronchus and lung cancer, breast cancer, thyroid cancer, and myeloid leukaemia for the period 1995- 2001 were studied. The incidence of the gastrointestinal tract cancers in the population of German was significantly lower than those for Bulgaria and for group B. The mortality from this disease of groups A, B and Bulgaria were significantly higher than in the control settlement. Standardized mortality of lung cancer in the population of the villages with highest and relatively high radiation risk was significantly higher than in German and Bulgaria. The incidence and mortality changes of diseases studied are a consequence of the impact of many factors. Moreover, they do not characterize the impact of the radiation factor.

An Overview of the Reimbursement Decision-Making Processes in Bulgaria As a Reference Country for the Middle-Income European Countries.

Policy makers face a lot of challenges in the process of drug reimbursement decision-making, especially in the context of entering the market of more and more innovative medicinal products (MPs). The aim of the current study is to make an overview of the reimbursement system development and to evaluate the access of innovative medicines, which have entered the EU-market in the period 2015-2017, in Bulgaria as reference example for middle-income European country. A literature and a legislative systematic review regarding the Bulgarian reimbursement system as well as a defining the number of available innovative reimbursed MPs in 2017 in Bulgaria was made. The reimbursement legislation in Bulgaria is quite unstable due to constant changes, which have been made, especially in the recent years. Despite this fact, the reimbursement process in Bulgaria is in accordance with the Transparency Directive. Bulgarian patients have a relatively delayed access to innovative medicines as only 5% of centrally authorized MPs in 2017 are available in the positive drug list (PDL), 16% of all in 2016 and 18%-in 2015. This could be explained by the long procedure for their appraisal in Bulgaria: the first step is issuing an opinion by the HTA Committee, followed by negotiation of discounts between the marketing authorization holder and the National Health Insurance Fund and making a final decision by the National Council on Prices and Reimbursement (NCPR) for the inclusion into the PDL. Optimization of the procedure for issuing reimbursement status for innovative MPs is needed, such as improvements in the process of conducting HTA reports and their appraisal, incorporation of adequate systems for following the effectiveness and safety of MPs in the real-world conditions, value-based pricing implementation, and increasing the financial control over the health insurance system.

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

2015-01-01

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.

We are delighted to present the Proceedings of the 18th International School on Condensed Matter Physics: Challenges of Nanoscale Science: Theory, Materials, Applications, organized by the Institute of Solid State Physics of the Bulgarian Academy of Sciences and chaired by Professor Alexander G Petrov. On this occasion the School was held in memory of Professor Nikolay Kirov (1943-2013), former Director of the Institute and Chairman between 1991 and 1998. The 18ISCMP was one of several events dedicated to the 145th anniversary of the Bulgarian Academy of Sciences in 2014, and was held in the welcoming Black Sea resort of St. Constantine and Helena near Varna, at the Hotel and Congress Centre Frederic Joliot-Curie. Participants from 16 countries delivered 32 invited lectures, and 71 contributed posters were presented over three lively and well-attended evening sessions. Manuscripts submitted to the Proceedings were refereed in accordance with the guidelines of the Journal of Physics: Conference Series, and we believe the papers published herein testify to the high technical quality and diversity of contributions. A satellite meeting, Transition Metal Oxide Thin Films - Functional Layers in Smart Windows and Water Splitting Devices: Technology and Optoelectronic Properties was held in parallel with the School (http://www.inera.org, 3-6 Sept 2014). This activity, which took place under the FP7-funded project INERA, offered opportunities for crossdisciplinary discussions and exchange of ideas between both sets of participants. As always, a major factor in the success of the 18ISCMP was the social programme, headed by the organized events (Welcome and Farewell Parties) and enhanced in no small measure by a variety of pleasant local restaurants, bars and beaches. We are most grateful to staff of the Journal of Physics: Conference Series for their continued support for the School, this being the third occasion on which the Proceedings have been published under its auspices.

Aging in the Republic of Bulgaria.

PubMed

Pitheckoff, Natalie

2017-10-01

Bulgaria, a southeastern European nation with 7.1 million inhabitants, is ranked 4th in the world for its rate of population aging. Bulgaria has one of the highest proportions of older adults in the world with approximately 20% aged 65 and older. Three main demographic factors have led to rapid population aging. These include emigration, high death rates, and low birth rates. This "perfect storm" of demographic factors has created numerous political, social, and economic challenges for Bulgaria. For example, informal support of older adults is declining as younger generations move abroad or to urban areas for greater employment opportunities. This has increased the need for formal long-term services and supports, which can be at odds with traditional values. Additionally, economic sustainability is a major concern for the nation as population aging and de-population continues. Few gerontological organizations, scholars, or secondary datasets exist in the country. To address these challenges, more research on aging is needed to encourage economic renewal, healthy aging policies, and long-term services and supports. © The Author 2017.

1H NMR spectroscopy of urine has been applied to exploring metabolomic differences between people diagnosed with Balkan endemic nephropathy (BEN), and treated by haemodialysis, and those without overt renal disease in Romania and Bulgaria. Convenience sampling was made from patients receiving haemodialysis in hospital and healthy controls in their village. Principal component analysis clustered healthy controls from both countries together. Bulgarian BEN patients clustered separately from controls, though in the same space. However, Romanian BEN patients not only also clustered away from controls but also clustered separately from the BEN patients in Bulgaria. Notably, the urinary metabolomic data of two people sampled as Romanian controls clustered within the Romanian BEN group. One of these had been suspected of incipient symptoms of BEN at the time of selection as a ‘healthy’ control. This implies, at first sight, that metabolomic analysis can be predictive of impending morbidity before conventional criteria can diagnose BEN. Separate clustering of BEN patients from Romania and Bulgaria could indicate difference in aetiology of this particular silent renal atrophy in different geographic foci across the Balkans.

Tracing How Normative Messages May Influence Physical Activity Intention.

PubMed

van Bavel, René; Esposito, Gabriele; Baranowski, Tom; Duch-Brown, Néstor

2017-04-01

Normative messages have been shown to increase intention to do physical activity. We traced how "positive" and "negative" normative messages influenced physical activity intention by comparing constructs of the model of goal-directed behavior with descriptive norms (MGDB + DNs) across control and treatment groups in an experiment. For this purpose, 16-24-year-old respondents (n = 1,200) in Bulgaria, Croatia, and Romania were asked about their age, sex, and levels of physical activity before being exposed to positive and negative normative messages and completing a questionnaire with MGDB + DNs scales. Different MGDB + DNs constructs were influenced by the normative messages: compared with the control, the negative message group showed stronger attitudes (p = .003) and the positive message group showed higher positive anticipated emotions (p = .005). The positive message's effect is consistent with the literature on conformity to social norms. The negative message's effect lends itself to interpretations based on social identity and deviance regulation theories.

Understanding informal payments for health care: the example of Bulgaria.

PubMed

Balabanova, Dina; McKee, Martin

2002-12-01

Throughout the 1990s, in response to funding deficits, out-of-pocket payment has grown as a share of total expenditure in countries in transition. A clear policy response to informal payments is, however, lacking. The current study explores informal payments in Bulgaria within a conceptual framework developed by triangulating information using a variety of methodologies. To estimate the scale and determinants of informal payments in the health sector of Bulgaria and to identify who benefits, the characteristics and timing of payments, and the reasons for paying. Data were derived from a national representative survey of 1547 individuals complemented by in-depth interviews and focus groups with over 100 respondents, conducted in Bulgaria in 1997. Informal payments are defined as a monetary or in-kind transaction between a patient and a staff member for services that are officially free of charge in the state sector. Informal payments are relatively common in Bulgaria, especially if in the form of gifts. Informal cash payments are universal for operations and childbirth, clear-cut and life-threatening procedures, in hospitals or elite urban facilities or well-known physicians. Most gifts were given at the end of treatment and most cash payments-before or during treatment. Wealthier, better educated, younger respondents tend to pay more often, as a means of obtaining better-quality treatment in a de facto two-tier system. Since the transition, informal payments had become frequent, explicit, solicited by staff, increasingly in cash, and less affordable. Informal payments stem from the low income of staff, patients seeking better treatment; acute funding shortages; and from tradition. Attitudes to informal payments range from strongly negative (if solicited) to tolerant (if patient-initiated), depending on the circumstances. The study provides important new insights into the incidence and nature of informal payments in the health sector in Bulgaria. Payments were less than expected, very complex, organised in a chaotic, although adaptive, system, and relatively equitable. The timing of payment and the presence of compulsion is a key factor in distinguishing between informal payments given in gratitude or as a bribe, and the latter are seen as problematic, needing to be addressed. Paying informally appeared to be a product of socio-economic reality rather than culture and tradition. The study showed that the principle of comprehensive free coverage existing in Bulgaria until 1989 has been significantly eroded. Initiating a public debate on informal payments is important in a health care reform process that purports to increase accountability.

The present study gives an account of the genetic structure in terms of distribution of a few genetic markers, viz., A1A2B0, Rh(D), G6PD deficiency and haemoglobin among the Rajaka caste population of Andhra Pradesh, India. The genetic relationships of the Rajaka caste with other Andhra caste populations were investigated in terms of genetic distance, i.e., Sq B (mn) of Balakrishnan and Sanghvi. Relatively lesser distance was established between the Rajaka and two Panchama castes. Also, the pattern of genetic distance corroborates the hierarchical order of the Hindu varna system.

Background The aim of the current study was to compare levels of energy balance-related behaviours (physical activity, sedentary behaviour, and dietary behaviours (more specifically water consumption, sugar-sweetened beverage consumption and unhealthy snacking)) in four- to six-year-old preschoolers from six European countries (Belgium, Bulgaria, Germany, Greece, Poland, and Spain) within the ToyBox cross-sectional study. Methods A sample of 4,045 preschoolers (4.77 ± 0.43 years; 52.2% boys) had valid physical activity data (steps per day), parents of 8,117 preschoolers (4.78 ± 0.46 years; 53.0% boys) completed a parental questionnaire with questions on sedentary behaviours (television viewing, computer use, and quiet play), and parents of 7,244 preschoolers (4.77 ± 0.44 years; 52.0% boys) completed a food frequency questionnaire with questions on water consumption, sugar-sweetened beverage consumption and unhealthy snacking. Results The highest levels of physical activity were found in Spain (12,669 steps/day on weekdays), while the lowest levels were found in Bulgaria and Greece (9,777 and 9,656 steps/day on weekdays, respectively). German preschoolers spent the least amount of time in television viewing (43.3 min/day on weekdays), while Greek preschoolers spent the most time in television viewing (88.5 min/day on weekdays). A considerable amount of time was spent in quiet play in all countries, with the highest levels in Poland (104.9 min/day on weekdays), and the lowest levels in Spain (60.4 min/day on weekdays). Belgian, German, and Polish preschoolers had the lowest intakes of water and the highest intakes of sugar-sweetened beverages. The intake of snacks was the highest in Belgian preschoolers (73.1 g/day) and the lowest in Greek preschoolers (53.3 g/day). Conclusions Across six European countries, differences in preschoolers’ energy balance-related behaviours were found. Future interventions should target European preschoolers’ energy balance-related behaviours simultaneously, but should apply country-specific adaptations. PMID:25785738

Perceptions of societal developmental hierarchies in Europe and beyond: A Bulgarian Perspective

2012-01-01

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. PMID:23807821

The Third International Workshop & Summer School on Plasma Physics (IWSSPP'08) organized by St Kliment Ohridsky University of Sofia, with co-organizers TCPA Foundation, Association EURATOM/IRNRE, The Union of the Physicists in Bulgaria, and the Bulgarian Academy of Sciences was held in Kiten, Bulgaria, at the Black Sea Coast, from 30 June to 5 July 2008. A Special Session on Plasmas for Environmental Issues was co-organised by the Institute of Plasmas and Nuclear Fusion, Lisbon, Portugal and the Laboratory of Plasmas and Energy Conversion, University of Toulouse, France. That puts the beginning of a series in Workshops on Plasmas for Environmental Issues, now as a satellite meeting of the European Physical Society Conference on Plasma Physics. As the previous issues of this scientific meeting (IWSSPP'05, J. Phys.: Conf. Series 44 (2006) and IWSSPP'06, J. Phys.: Conf. Series 63 (2007)), its aim was to stimulate the creation and support of a new generation of young scientists for further development of plasma physics fundamentals and applications, as well as to ensure an interdisciplinary exchange of views and initiate possible collaborations by bringing together scientists from various branches of plasma physics. This volume of Journal of Physics: Conference Series includes 38 papers (invited lectures, contributed talks and posters) devoted to various branches of plasma physics, among them fusion plasma and materials, dc and microwave discharge modelling, transport phenomena in gas discharge plasmas, plasma diagnostics, cross sections and rate constants of elementary processes, material processing, plasma-chemistry and technology. Some of them have been presented by internationally known and recognized specialists in their fields; others are MSc or PhD students' first steps in science. In both cases, we believe they will raise readers' interest. We would like to thank the members of both the International Advisory Committee and the Local Organizing Committee, the participants who sent their manuscripts and passed through the (sometimes heavy and troublesome) refereeing and editing procedure and our referees for their patience and considerable effort to improve the manuscripts. We greatly appreciate the financial support from the sponsors: the Department for Language Teaching and International Students at the University of Sofia, the Austrian Science and Research Liason Offices and the Bulgarian Nuclear Society. We would like to express our gratitude to the invited lecturers who were willing to pay the participation fee. In this way, in addition to the intellectual support they provided by means of their excellent lectures, they also supported the school financially. E Benova, F M Dias and Yu Lebedev

Intracranial tumors (ICTs) attract numerous scientific teams and tremendous financial resources worldwide. These lesions of the central nervous system (CNS) can be both benign and malignant in biological behavior as well as local or metastatic in origin. We compared data from two studies on primary and metastatic ICTs from Brazil and Bulgaria, based on histopathologically confirmed ICTs from tertiary health centers. Primary ICTs significantly outweigh the frequency of metastatic ICTs. Primary ICTs represent 86.45% in Brazil and 69.17% in Bulgaria, with around 60% of their totals being malignant. There is a statistical dominance of tumors from the neuroepithelial origin, with the most common entry being glioblastoma multiforme. The second-most common primary ICT group comprises tumors of meningeal origin. Metastatic ICTs show great variance; 13.55% in Brazil and 31.38% in Bulgaria of all ICT cases being attributed to them. However, metastatic ICTs are even a more diverse group than neuroepithelial tumors, with the majority of this group comprising metastatic colorectal adenocarcinoma (almost exclusively in males), metastatic breast adenocarcinoma in females, metastatic pulmonary carcinomas (primarily from the non-small cell group with a male predominance), and metastatic melanoma with an even gender ratio.

Pharmacies in Bulgaria have a monopoly on the dispensing of medicinal products that are authorized in the Republic of Bulgaria, as well as medical devices, food additives, cosmetics, and sanitary/hygienic articles. Aptekari (pharmacists) act as responsible pharmacists, pharmacy owners, and managers. They follow a five year Masters of Science in Pharmacy (M.Sc. Pharm.) degree course with a six month traineeship. Pomoshnik-farmacevti (assistant pharmacists) follow a three year degree with a six month traineeship. They can prepare medicines and dispense OTC medicines under the supervision of a pharmacist. The first and second year of the M.Sc. Pharm. degree are devoted to chemical sciences, mathematics, botany and medical sciences. Years three and four center on pharmaceutical technology, pharmacology, pharmacognosy, pharmaco-economics, and social pharmacy, while year five focuses on pharmaceutical care, patient counselling, pharmacotherapy, and medical sciences. A six month traineeship finishes the fifth year together with redaction of a master thesis, and the four state examinations with which university studies end. Industrial pharmacy and clinical (hospital) pharmacy practice are integrated disciplines in some Bulgarian higher education institutions such as the Faculty of Pharmacy of the Medical University of Sofia. Pharmacy practice and education in Bulgaria are organized in a fashion very similar to that in most member states of the European Union. PMID:28970446

Chemical Education in Bulgaria

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.

A detailed analysis of the variations of the stratospheric and mesospheric ozone over Bulgaria, in the period 1996-2012, is presented in the article on the basis of ground and satellite measurements of the Total Ozone Content (TOC). The move of the most important components: yearly running mean values, amplitudes and phases of the first four harmonics of the seasonal cycle. Their mean values for the period and the existing long term trends have been found. An evaluation of the general characteristics of the short term variability of the Total Ozone Content (TOC) over Bulgaria also has been made in the article. The impact of the planetary wave activity of the stratosphere on the total ozone has been studied and the climatology of the oscillation amplitudes with periods of 4, 7, 11 and 25 days has been defined.

Renewable energy sources in Bulgaria: Current state and trends

NASA Astrophysics Data System (ADS)

Kolev, K.

The over-dependency of Bulgaria on imported fuel stressed the importance of developing a new energy strategy based on energy saving which includes also using renewable energy sources (RES). The target is the substitution of at least 2 percent of the real primary energy consumption with RES by 2010. The author gives a generalized analysis of the available RES in Bulgaria -solar, wind, geothermal, biomass and mini-hydraulic. The potentialities of each source for its usage as a suitable energy supply are pointed out, as well as the current status of research and implementation work, problems connected with legislation, financing and production of particular facilities. The governmental policy concerning RES is considered briefly. A description is given to the project 'Technical and Economical Assessment of Possibilities for Expansion of the RES-part in the Energy Balance of the Country' developed and started in 1994 in the framework of the PHARE program.

Nursing ethics: what lies ahead? The case of Bulgaria.

Popova, S

1996-03-01

In Bulgaria, we are sharing a transition to a civic society and a market economy, which means transferring to new parameters of our culture. Many old customs based on coercion, obedience and unacceptable interference are gradually dying out, and new principles tend to shape the way we live our collective lives. These include the ethics of partnership, which tend to create an assertion of individual rights and an affirmation of free will and autonomy, and within which the individual is protected in the pursuit of personal judgements. It is remarkable, however, that we have so much difficulty in talking about and identifying the most beneficial approaches for the achievement of the new design of our society. In this paper, I propose to illustrate the current crisis in nursing ethics with information mainly from Bulgaria. However, I think that the problems and trends in the other Eastern European countries are similar.

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 and monuments are legally protected under the Law of cultural heritage and managed by the Ministry of culture and local authorities. This work is part of HERAS Project (2 (4i)-3.1-26 MIS ETC Code: 578 "Submarine Archaeological Heritage on the Western Black Sea Shelf - HERAS, Contract № 64727/09.08.2013), financed by European Union under the CBC Program Romania-Bulgaria.

Bulgarian Turkish emigration and return.

Vasileva, D

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 differences. The unifying factor was the Islamic religion. For those returning to Bulgaria, the change in regime meant the government worked to solve the emigrants' housing problems and teaching Turkish in primary and secondary schools. The result of this massive migration has been a change in the demographics and social structure of Bulgaria, and the realization that forceful migration is inefficient in solving problems.

Hepatitis a virus genotypes and strains from an endemic area of Europe, Bulgaria 2012-2014.

Hepatitis A virus (HAV) infection is endemic in Eastern European and Balkan region countries. In 2012, Bulgaria showed the highest rate (67.13 cases per 100,000) in Europe. Nevertheless, HAV genotypes and strains circulating in this country have never been described. The present study reports the molecular characterization of HAV from 105 patients from Bulgaria. Anti-HAV IgM positive serum samples collected in 2012-2014 from different towns and villages in Bulgaria were analysed by nested RT-PCR, sequencing of the VP1/2A region and phylogenetic analysis; the results were analysed together with patient and geographical data. Phylogenetic analysis revealed two main sequence groups corresponding to the IA (78/105, 74%) and IB (27/105, 26%) sub-genotypes. In the IA group, a major and a minor cluster were observed (62 and 16 sequences, respectively). Most sequences from the major cluster (44/62, 71%) belonged to either of two strains, termed "strain 1" and "strain 2", differing only for a single specific nucleotide; the remaining sequences (18/62, 29%) showed few (1 to 4) nucleotide variations respect to strain 1 and 2. Strain 2 is identical to the strain previously responsible for an outbreak in the Czech Republic in 2008 and a large multi-country European outbreak caused by contaminated mixed frozen berries in 2013. Most sequences of the IA minor cluster and the IB group were detected in large/medium centers (LMCs). Overall, sequences from the IA major cluster were more frequent in small centers (SCs), but strain 1 and strain 2 showed an opposite relative frequency in SCs and LMCs (strain 1 more frequent in SCs, strain 2 in LMCs). Genotype IA predominated in Bulgaria in 2012-2014 and phylogenetic analysis identified a major cluster of highly related or identical IA sequences, representing 59% of the analysed cases; these isolates were mostly detected in SCs, in which HAV shows higher endemicity than in LMCs. The distribution of viral sequences suggests the existence of some differences between the transmission routes in SCs and LMCs. Molecular characterization of an increased number of isolates from Bulgaria, regularly collected over time, will be useful to explore specific transmission routes and plan appropriate preventing measures.

Exploring seismicity using geomagnetic and gravity data - a case study for Bulgaria

NASA Astrophysics Data System (ADS)

Trifonova, P.; Simeonova, S.; Solakov, D.; Metodiev, M.

2012-04-01

Seismicity exploration certainly requires comprehensive analysis of location, orientation and length distribution of fault and block systems with a variety of geophysical methods. In the present research capability of geomagnetic and gravity anomalous field data are used for revealing of buried structures inside the earth's upper layers. Interpretation of gravity and magnetic data is well known and often applied to delineate various geological structures such as faults, flexures, thrusts, borders of dislocated blocks etc. which create significant rock density contrast in horizontal planes. Study area of the present research covers the territory of Bulgaria which is part of the active continental margin of the Eurasian plate. This region is a typical example of high seismic risk area. The epicentral map shows that seismicity in the region is not uniformly distributed in space. Therefore the seismicity is described in distributed geographical zones (seismic source zones). Each source zone is characterized by its specific tectonic, seismic, and geological particulars. From the analysis of the depth distribution it was recognized that the earthquakes in the region occurred in the Earth's crust. Hypocenters are mainly located in the upper crust, and only a few events are related to the lower crust. The maximum depth reached is about 50 km in southwestern Bulgaria; outside, the foci affect only the surficial 30-35 km. Maximum density of seismicity involves the layer between 5 and 25 km. This fact determines the capability of potential fields data to reveal crustal structures and to examine their parameters as possible seismic sources. Results showed that a number of geophysically interpreted structures coincide with observed on the surface dislocations and epicenter clusters (well illustrated in northern Bulgaria) which confirms the reliability of the applied methodology. The complicated situation in southern Bulgaria is demonstrated by mosaics structure of geomagnetic field, complex configuration of gravity anomalies and spatial seismicity distribution. Well defined (confirmed by geophysical, geological and seismological data) are the known earthquake source zones (such as Sofia, Kresna, Maritsa, Yambol ) in this part of the territory of Bulgaria. Worth while are the results where no surface structures are present (e.g. Central Rhodope zone and East Rhodope zone, where the 2006 Kurdzhali earthquake sequence is realized). In those cases, gravity and magnetic interpretations proved to be a suitable enough technique which allows determining of position and parameters of the geological structures in depth.

The authors describe a case of a congenital Mullerian anomaly, uterus unicornis with missing right fallopian tube. An in Vitro Fertilization Pre-Embryo Transfer (IVF-ET) procedure was done and presently is known that the patient has left fallopian tube and left ovary, two kidneys, and right ovary is missing. No diagnostic laparoscopy and hysteroscopy were done, only hysterosalpingography (HSG) before the IVF procedure. Several days after the follicular puncture of the left ovary the patient was urgently admitted to the hospital for specialized gynaecology in Varna. Transabdominal ultrasonography showed right ovary atypically located immediately next to the liver and with emerging theca-lutein cysts. PMID:27275261

Infections of humans with the tick-borne Crimean-Congo hemorrhagic fever virus (CCHFV) can cause a severe hemorrhagic fever with case fatality rates of up to 80%. Most humans are infected by tick bite, crushing infected ticks by hand or by unprotected contact with blood of viremic mammals. Next to the notified human CCHF cases, the real distribution and the situation in animals in Southeastern Europe are nearly unknown. Since domestic ruminants play a crucial role in the life cycle of the vector ticks and the transmission and amplification of the virus, the antibody prevalence in those animals is a good indicator for the presence of CCHFV in a region. Therefore, the prevalence of CCHFV-specific antibodies was investigated in domestic ruminants of different regions of Bulgaria and Turkey. Sera of 1165 ruminants were tested and a prevalence of up to 90% was identified. The overall prevalence for Bulgaria was 26% and for Turkey 57%. The results highlight the risk of human infections in those regions and the importance of the investigation of the prevalence in animals for identification of risk areas. This article provides a unique overview about published CCHFV antibody prevalence in animals in comparison to human incidences in different areas of Bulgaria and Turkey. Although it will help to complete the understanding of the CCHFV situation in these countries, it also demonstrates the lack of unpublished and published data even in these highly endemic areas.

Varicella infection in a non-universally vaccinated population: Actual epidemiology in Bulgaria (2013-2015).

PubMed

Todorova, Tatina T

Varicella is a common and usually mild disease but it has great importance in regard to general infectious morbidity. The current study aimed to characterize possible risk factors of varicella epidemiology in Bulgaria, a country where infection follows its natural epidemiological pattern as no mandatory or recommended vaccine is currently applied. Administrative regions of Bulgaria were used as units of observation and a set of sociodemographic and economic determinants, as well as geographic location (south or north) were tested for associations with the mean 3-year varicella incidence rates (2013-2015). The proportion of urban population, proportion of females, number of health care units and proportion of urban population aged <10 years were the four sociodemographic variables most strongly and significantly correlated (p<0.05) with varicella frequency (Spearman's rank correlation coefficients of 0.62, 0.47, 0.43, and 0.38, respectively). After reducing the number of intercorrelated factors to a few principal components and accounting for confounders, the demographic component and geographic location remained most robustly associated with varicella incidence in Bulgaria (adjusted R 2 of 0.51, p<0.001). The results obtained identify important determinants in the local epidemiology of varicella and show that community characteristics should be considered, to improve our understanding of varicella distribution.

The International Summer School on Vacuum, Electron and Ion Technologies (VEIT) has been organized biennially since 1977 when the series of VEIT Schools was launched by the Institute of Electronics, Bulgarian Academy of Sciences with the aim to act as a forum for interchange and dissemination of knowledge and ideas on the latest developments in electron-, ion-, and plasma-assisted technologies. Beginning from 2001, the school has been jointly organized with the Institute of Ion Beam Physics and Materials Research, Forschungszentrum Dresden-Rossendorf, Germany. Whereas, the school initially provided a meeting place for researchers mainly from Eastern and Central European countries, its importance grew issue by issue. The school is now a major scientific event and a meeting place for young scientists from Eastern and Western Europe involved in research and development associated with high-tech industries. Many former school participants have gone on to become leading scientists in research establishments and companies throughout the world. Leading international companies, such as High Voltage Engineering, Balzers, Varian, and Hauzer have used the VEIT forum to present their products through oral presentations, poster contributions or exhibits. The School Proceedings have been published in special issues of the international journals Vacuum, Plasma Processes and Polymers, Journal of Physics: Conference Series. The Sixteenth VEIT school was held in the Black Sea resort Sunny Beach, Bulgaria on 28 September to 2 October 2009. It was attended by close to 110 participants from 13 countries: Belgium, Bulgaria, Czech Republic, France, Germany, The Netherlands, Romania, Slovak Republic, Spain, Sweden, Ukraine, UK and USA. Following the tradition of publishing the VEIT Proceedings, a selection of papers presented at the event is published in this volume of Journal of Physics: Conference Series, under the originality and quality criteria of acceptance by the journal, including peer reviewing. The school comprised nine oral and three poster sessions. Seventeen invited talks of general interest and six progress reports were presented orally. In total 63 contributed papers were presented during the poster sessions. There were several scientific highlights covering fundamentals of interaction of fast particles with solids and challenging practical applications ranging from novel techniques for creating hard coatings, optical/protective layers, biocompatible materials to nanosized structures produced by evaporation, sputtering or external irradiation. Latest results were presented on ion-beam synthesis and modification in both low-energy (deposition and film growth) and high-energy (sputtering, implantation) regimes, and processing of solid materials aiming at patterning the surface or to create nanophase systems towards for electronic or tribological/wear resistant applications. Despite the busy scientific program, the atmosphere was relaxed and informal. The early afternoons of most conference days were free to stimulate both scientific and social interaction between participants, which often took place on the beach. The social program included a welcome reception, a conference banquet, and an outing to historical landmarks in Bulgaria. VEIT 2009 owes its success to many people. The International Advisory Committee shaped the scientific program and ensured high-quality plenary presentations by careful selection of invited speakers. The Local Committee bore the brunt of the organization both at the conference site and in dealing with correspondence, abstracts, and manuscripts for these proceedings. We are grateful to our sponsors Forschungszentrum Dresden-Rossendorf, Dresden, Germany and Bulgarian Academy of Sciences, Sofia, Bulgaria for their generosity that enabled us to support the attendance of students and provided support to deal with mailing, printing, renting the conference site, etc. We would like to thank also all authors for their valuable contributions to these proceedings and to the school, as well as all reviewers for their important work. The next conference in the series will be held in September 2011. Wolfhard Möller, Nikolay Guerassimov, Chavdar Ghelev Guest Editors

Crimean-Congo haemorrhagic fever (CCHF) was diagnosed in a United Kingdom traveller who returned from Bulgaria in June 2014. The patient developed a moderately severe disease including fever, headaches and petechial rash. CCHF was diagnosed following identification of CCHF virus (CCHFV) RNA in a serum sample taken five days after symptom onset. Sequence analysis of the CCHFV genome showed that the virus clusters within the Europe 1 clade, which includes viruses from eastern Europe.

Currently, a wide spectrum of retrospective studies regarding the incidence of TC among children and adults are available in the world literature, but none of them are comparative, aiming to distinguish etiological diversity depending on the different geographic areas. This study aimed to investigate the epidemiology of TC in Plovdiv, Bulgaria and Thessaloniki, and Greece, and to compare the results and predominant etiological agents using retrospective comparative analysis for an 11-year time period. The subjects included were selected from archives of the Mycological Laboratory of the University Dermatologic Clinic, University Hospital "St. George" Plovdiv, Bulgaria, and the Mycological Laboratory of the First Dermatology Department of Aristotle University Thessaloniki, Greece, by retrospective analysis of data from an 11-year time period (2004-2014). A total count of 374 children aged 0-18, with confirmed diagnosis of TC via direct mycological examination and culture were included (128 children from Plovdiv, Bulgaria, and 246 children from Thessaloniki, Greece). Samples were plated on Sabouraud agar, followed by species identification of the isolated colonies. Our results demonstrate that the incidence of TC in the region of Bulgaria and Thessaloniki for the investigated period was lower than for the previously reported period. In Plovdiv, Bulgaria, it was 1.20 ± 0.09 % (n = 172 from a total count of 14,278 cases of mycoses), as the disease accounts for 23.10 ± 1.79 % of all mycological infections among the pediatric population and 0.36 ± 0.05 % (n = 49 from a total count of 13,724) among the adults patients in Plovdiv, Bulgaria. The incidence of the disease during the period 2004-2014 in Thessaloniki was 2.49 ± 0.15 % (n = 253 cases of TC from a total count of 10,168 mycoses), as it accounts for approximately 27.06 ± 1.47 % of mycological infections among the pediatric population in Thessaloniki, Greece, and 0.08 ± 0.03 % (n = 7 from a total count of 9259) of the population of adult patients with mycoses. Our study confirmed the presumption that M. canis is the leader among the causative agents in TC in children in both of the included countries, but its presence in the etiology of disease in adult patients was very low and nonsignificant. We categorically identified dominance of the female gender among the children with TC in Plovdiv, Bulgaria; while in Thessaloniki, Greece, the gender distribution had an almost equal ratio of males to females. Our results suggest that the gender predisposition depends also on the investigated geographic region and the time of the study, rather than only on the causative pathogen and age.

Earthquake scenarios based on lessons from the past

Earthquakes are the most deadly of the natural disasters affecting the human environment; indeed catastrophic earthquakes have marked the whole human history. Global seismic hazard and vulnerability to earthquakes are increasing steadily as urbanization and development occupy more areas that are prone to effects of strong earthquakes. Additionally, the uncontrolled growth of mega cities in highly seismic areas around the world is often associated with the construction of seismically unsafe buildings and infrastructures, and undertaken with an insufficient knowledge of the regional seismicity peculiarities and seismic hazard. The assessment of seismic hazard and generation of earthquake scenarios is the first link in the prevention chain and the first step in the evaluation of the seismic risk. The implementation of the earthquake scenarios into the policies for seismic risk reduction will allow focusing on the prevention of earthquake effects rather than on intervention following the disasters. The territory of Bulgaria (situated in the eastern part of the Balkan Peninsula) represents a typical example of high seismic risk area. Over the centuries, Bulgaria has experienced strong earthquakes. At the beginning of the 20-the century (from 1901 to 1928) five earthquakes with magnitude larger than or equal to MS=7.0 occurred in Bulgaria. However, no such large earthquakes occurred in Bulgaria since 1928, which may induce non-professionals to underestimate the earthquake risk. The 1986 earthquake of magnitude MS=5.7 occurred in the central northern Bulgaria (near the town of Strazhitsa) is the strongest quake after 1928. Moreover, the seismicity of the neighboring countries, like Greece, Turkey, former Yugoslavia and Romania (especially Vrancea-Romania intermediate earthquakes), influences the seismic hazard in Bulgaria. In the present study deterministic scenarios (expressed in seismic intensity) for two Bulgarian cities (Rouse and Plovdiv) are presented. The work on scenarios was guided by the perception that usable and realistic (also in the sense of being compatible with seismic histories of cities that are several centuries long) ground motion maps had to be produced for urban areas. By deterministic scenario it is mean a representation of the severity of ground shaking over an urban area, using one or more hazard descriptors. Such representation can be obtained: - either from the assumption of a "reference earthquake" specified by a magnitude or an epicentral intensity, associated to a particular earthquake source - or, directly, showing values of local macroseimic intensity generated by a damaging, real earthquakes of the past. In the study we chose for the second method using the values of macroseimic intensity caused by damaging historical earthquakes (the 1928 quakes in southern Bulgaria; the 1940 and the 1977 Vrancea intermediate earthquakes) - lessons from the past. Such scenarios are intended as a basic input for developing detailed earthquake damage scenarios for the cities and can be used in earthquake-safe town and infrastructure planning.

Bulgaria is rich in the remains of past human settlements and activity. For example, along northern part of the Bulgarian coast, numerous underwater and coastal archaeological sites from different periods have been discovered - Prehistory, Antiquity (ancient Greek, Hellenistic, Roman), Mediaeval (Early Byzantium, Bulgarian). The most significant of them are: Durankulak archaeological complex with the largest Prehistoric necropolis in the world, Prehistoric necropolis at the area of Lake Shablenska Tuzla, Antique settlements Caron Limen and Bizone, archeological reserve Yalata, Antique and Medieval castle at Cape Kaliakra etc. As, this north part of Bulgarian coast has a huge archaeological potential there is a ground for thinking that the remains of other periods as well as a brand new, previously unknown sites can be discovered in the near future. This does not exclude the probability of being randomly found individual objects that largely can be prevented from archaeological contexts. Therefore it is important that these archeological sites are protected properly and preserved for future generations. In Bulgaria such sites and monuments are legally protected under the Law of cultural heritage and managed by the Ministry of culture and local authorities. However, today most objects and sites, as part of common European historical and cultural heritage are posed to a variety of potential impacts and treats, both natural and human-induced. This study discusses the implications of natural factors, (such as climate change, extreme waves, erosion and shoreline changes) and human contributions (coastal infrastructures, tourism and insufficient management by decision-makers) to coastal and underwater cultural heritage along the north portion of Bulgarian coast. Major natural processes that seriously affect on coastal and maritime heritage environment are direct physical impact by global climate changes, sea level rise and caused increase of waves and storms, acceleration of erosion and coastal landslides. Among human activities that might have direct or indirect adverse impact on cultural heritage the main are coastal and underwater developments and infrastructures. These are building of coast- and shore-protection structures, roads, placing different types of pipeline (a recent case from Bulgaria is envisaged construction of gas pipeline "South Stream"). Other categories of anthropogenic impacts, such as coastal tourism and expansion of settlements, etc. are less negative factors, but locals and visitors can accidentally damage monuments, or in most of the cases by not being aware of the presence and importance of a archeological site. Finally, insufficient decision-making and management of coastal and underwater cultural heritage can also have potential adverse impact. Recommendations for mitigation and protection measures are also outlined in the end. This work is a part of the Project "Submarine Archaeological Heritage on the Western Black Sea Shelf - HERAS", financed by European Union under the CBC Program Romania-Bulgaria.

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.

Ancient (proto-) Bulgarians have long been thought of as a Turkic population. However, evidence found in the past three decades shows that this is not the case. Until now, this evidence has not included ancient mitochondrial DNA (mtDNA) analysis. To fill this void, we collected human remains from the 8th to the 10th century AD located in three necropolises in Bulgaria: Nojarevo (Silistra region) and Monastery of Mostich (Shumen region), both in northeastern Bulgaria, and Tuhovishte (Satovcha region) in southwestern Bulgaria. The phylogenetic analysis of 13 ancient DNA samples (extracted from teeth) identified 12 independent haplotypes, which we further classified into mtDNA haplogroups found in present-day European and western Eurasian populations. Our results suggest a western Eurasian matrilineal origin for proto-Bulgarians, as well as a genetic similarity between proto- and modern Bulgarians. Our future work will provide additional data that will further clarify proto-Bulgarian origins, thereby adding new clues to the current understanding of European genetic evolution.

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.

An aseptic meningitis outbreak emerged in two regions in Bulgaria in 2012 and echovirus 30 (E30) was established as the aetiological agent by cell culture isolation, serological test, and molecular-based techniques. A total of 157 patients with aseptic meningitis were investigated, of which 117 were confirmed as having E30-associated disease. Molecular analysis of 12 E30 isolates revealed 99-100% nucleotide and amino-acid identity between them and a close correlation with a Greek strain involved in an E30 outbreak in 2012. Children aged 5-14 years were mainly affected, which could reflect the absence of E30 epidemics in Bulgaria for a period of 11 years. The first case with E30 isolation (a 2-year-old patient from Plovdiv) was notified at the end of April 2012. This was most likely the index case, from which the spread of the virus started, causing sporadic cases first, which later led to an aseptic meningitis outbreak facilitated by person-to-person viral transmission.

'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. © London School of Economics and Political Science 2014.

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.

In Bulgaria the previously (1970-1985) existing population based cervical cancer screening was replaced in the early 1990s with an opportunistic model due to political and socioeconomic reasons. As a result, in the last 20 years, cervical cancer incidence and mortality rates steady increased. The objective of the EUROCHIP project in Bulgaria was to evaluate the readiness of the health system as well as health providers' attitudes to implementation in the country of a population based screening program for cervical cancer. Using a structured questionnaire, a convenience sample of medical specialists representing different actors involved in cervical cancer prevention, treatment, financing and policy were interviewed. The majority of interviewed practitioners worried that organization and implementation of an effective population-based cervical cancer screening program is not possible in the current unstable health system. A nostalgic attitude to the cervical cancer screening, performed in the past and pessimistic view on the capability of the current health system to cope are strong. As main barriers to implementation of an effective program were pointed financial and organizational ones. Motivation for gynecologists to perform smear test should include better information, organization and payment. Medical specialists in Bulgaria are aware of the alarming rates of cervical cancer incidence and mortality in the country. However, due to the insufficient communication and interaction between policy makers and front-line health care staff, they do not have enough information on the ongoing programs. Absence of health policy regarding screening is considered as main barrier for implementation of an effective screening program.

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

The BS-MFC entered the Copernicus Marine Environment Monitoring Service (CMEMS, http://marine.copernicus.eu/) in October 2016, providing regular and systematic information about the ocean state in the Black Sea in operational mode. An expert team constitutes the BS-MFC Consortium: the Institute of Oceanology, Bulgarian Academy of Sciences (IO-BAS, Bulgaria) coordinates the service and the management in collaboration with Fondazione Centro Euro-Mediterraneo sui Cambiamenti Climatici (CMCC, Italy), Helmholtz-Zentrum Geesthacht - Institute of Coastal Research (HZG, Germany), the University of Liege (ULG, Belgium), the Sofia University "St. Kliment Ohridski (USOF, Bulgaria) and the Eurasia Earth Sciences Institute - Istanbul Technical University (ITU, Turkey). The system provides a complete data catalogue for the Black Sea ocean variables such as temperature, salinity, sea level, currents, biogeochemistry and waves through a technologically advanced and resilient service, which is fully interconnected with the other Centers in the Copernicus network. The high level BS-MFC architecture is based on 3 Production Units, for Physics, Biogeochemistry and Waves products respectively, a Dissemination/Archiving Unit for the delivery of the products and their archiving/accessibility, a Local Service Desk connected to the CMEMS Service Desk devoted to support all the operational activities, and backup units for all the main service components. Products consist of analysis/hindcast, 10-days forecast and reanalysis, describing the physical (currents, temperature, salinity, sea level, mixed layer depth and bottom temperature), the biogeochemical state and waves. To implement and improve the service, the BS-MFC has detailed an evolution plan, actually under implementation, devoted to establish, assess and improve the systems and their operational functionalities, providing some improvements from the scientific point of view concerning the modeling components (e.g., the fully aligned Physics, Biogeochemistry and Waves systems, the open boundary conditions at the Bosporus, the state-of-the-art core models and increased spatial resolution among the major actions) and high quality products, towards an optimal interface between the Mediterranean and the Black Seas.

The Bulgarian Black Sea coast is about 412 km long, stretching between cape Sivriburun on the North and Rezovska River mouth on the South. At present, coastal erosion is a common process affecting 61% of the Bulgarian coast, while the sandy beaches comprise at least 30 %. Large number of coast-protection measures has been used to solve and manage the erosion/landslide problems, as most of these methods have involved "hard" stabilisation options such as: solid groins, dikes and seawalls. Design and construction of such protection structures has been increased in particular over the last few decades. About 217 technogenous objects have been indicated as port and coastal defence structures that currently constitute 17 % of the whole Bulgarian coastline. As a result, for a 50-year period (1960-2008) the amount of sediment material, incoming from cliff erosion, river solid discharge and wind-blown material has decreased from 4 979 700 Mg/y to 1 221 300 Mg/y. This in turn has provoked a reduction of sediment supply, sandy beach degradation and even occurrence of new erosion spots. Therefore, the major causes for progressive erosion along the Bulgarian coast could be mostly related to expanding human influence in terms of maritime constructions, dredging works and river corrections. The study is designed to trace the important issues of finding the extent of technogenous impact on the coastal zone of Bulgaria in order to delimitate the areas most influenced by coastline armouring. Topographic maps and GPS field survey data were used for identifying various types of port and coast-protection structures along the coastline. Data processing, mapping and analysis, as well as assessment of technogenous impact on the coastline were methodologically performed with tools of GIS ArcInfo 9.2. To evaluate the extent of anthropogenic influence on the Bulgarian Black Sea coast the coefficient of technogenous impact K was used, which serves for quantitative assessment of the impact of maritime hydraulic structures on the coast. This coefficient represents the ratio between total length of protection structures/objects (groins, moles, seawalls, dikes, navigational channels and permeable bridges) and total length of the coastline. According to this methodology the extent of technogenous impact is considered as minimal at K = 0.0001-0.1; average when K = 0.11-0.5; maximal at K = 0.51-1.0 and extreme if K > 1.0. The coefficient of technogenous impact on the whole Bulgarian coastline was estimated to be K = 0.17, which determines the extent of coastline armouring with port/coast-protection structures as average. Although this value for K of the entire coast could be acceptable, there are large coastal units, distinguished with significant concentration of maritime structures, and these are the largest bays along the Bulgarian shore: Varna Bay, where K reaches to 0.88 and Bourgas Bay with K = 0.26. The main findings from the study reveal an increasing human influence due to coastal defence activities at the Bulgarian Black Sea coast particularly expanded over the last few decades. Instead of soft protection alternatives, the construction of hard stabilisation structures, such as groins, dikes and seawalls, have been assumed as a common solution to prevent the coastline. As a result, the sporadic natural erosion in the near past has turned into human-caused and has become critical at many coastal units. The coefficient K could be used as an indicator for the extent of technogenous impact and would allow quantifying coastline modifications related to maritime structures (port and coast-protection).

The assessment of waste management systems for electrical and electronic equipment (WEEE) from developed economies (Germany, Sweden and Italy) and developing countries (Romania and Bulgaria), is discussed covering the period 2007-2014. The WEEE management systems profiles are depicted by indicators correlated to WEEE life cycle stages: collection, transportation and treatment. The sustainability of national WEEE management systems in terms of greenhouse gas emissions is presented, together with the greenhouse gas efficiency indicator that underlines the efficiency of WEEE treatment options. In the countries comparisons, the key elements are: robust versus fragile economies, the overall waste management performance and the existence/development of suitable management practices on WEEE. Over the life cycle perspective, developed economies (Germany, Sweden and Italy) manage one order of magnitude higher quantities of WEEE compared to developing countries (Romania and Bulgaria). Although prevention and reduction measures are encouraged, all WEEE quantities were larger in 2013, than in 2007. In 2007-2014, developed economies exceed the annual European collection target of 4 kg WEEE/capita, while collection is still difficult in developing countries. If collection rates are estimated in relationship with products placed on market, than similar values are registered in Sweden and Bulgaria, followed by Germany and Italy and lastly Romania. WEEE transportation shows different patterns among countries, with Italy as the greatest exporter (in 2014), while Sweden treats the WEEE nationally. WEEE reuse is a common practice in Germany, Sweden (from 2009) and Bulgaria (from 2011). By 2014, recycling was the most preferred WEEE treatment option, with the same kind of rates performance, over 80%, irrespective of the country, with efforts in each of the countries in developing special collection points, recycling facilities and support instruments. The national total and the recycling carbon footprints of WEEE are lower in 2013 than in 2007 for each country, the order in reducing the environmental impacts being: Germany, Italy, Sweden, Bulgaria and Romania. The negative values indicate savings in greenhouse gas emissions. In 2013, the GHG efficiency shows no differences of the WEEE management in the developed and developing countries.

Within an underlying health-impairing process, work stressors exhaust employees' mental and physical resources and lead to exhaustion/burnout and to health problems, with health-impairing behaviors being one of the potential mechanisms, linking burnout to ill health. The study aims to explore the associations between burnout and fast food consumption, exercise, alcohol consumption and painkiller use in a multinational sample of 2623 doctors, nurses and residents from Greece, Portugal, Bulgaria, Romania, Turkey, Croatia and Macedonia, adopting a cross-national approach. Data are part of the international cross-sectional quantitative ORCAB survey. The measures included the Maslach Burnout Inventory and the Health Behaviors Questionnaire. Burnout was significantly positively associated with higher fast food consumption, infrequent exercise, higher alcohol consumption and more frequent painkiller use in the full sample, and these associations remained significant after the inclusion of individual differences factors and country of residence. Cross-national comparisons showed significant differences in burnout and health behaviors, and some differences in the statistical significance and magnitude (but not the direction) of the associations between them. Health professionals from Turkey, Greece and Bulgaria reported the most unfavorable experiences. Burnout and risk health behaviors among health professionals are important both in the context of health professionals' health and well-being and as factors contributing to medical errors and inadequate patient safety. Organizational interventions should incorporate early identification of such behaviors together with programs promoting health and aimed at the reduction of burnout and work-related stress.

Informal payments for health care are a well-known phenomenon in many health care systems around the world. While informal payments could be an important source of health care financing, they have an adverse impact on efficiency and access to care, and are a major impediment to ongoing health care reforms. This paper aims to study the scale and patterns of informal patient payments for out-patient and in-patient services in three former-socialist countries: Bulgaria, Hungary and Ukraine. The data are collected in 2010 and 2011 based on national representative samples and are analysed in pooled models to explain variations in payments. The results of the cross-country comparison suggest a relatively higher prevalence of informal patient payments in Ukraine and Hungary than in Bulgaria, where patients also have to pay formal user charges in the public sector. Nevertheless, informal payments for hospitalization in Bulgaria are quite extensive. We observe some differences in informal payments across the years. Variations in payment size are mainly explained by the nature, type and need for services, fee awareness and, on some occasions, by household income. Interpreted within the context of structural differences (e.g. reform paths, regulations, funding, user fees, anti-corruption policies), the findings of our study have implications on how to address informal payments for health care. © The Author 2016.

Crimean-Congo hemorrhagic fever (CCHF) is a tick-borne human viral disease with fatality rate up to 30%. Two genetic lineages of CCHF virus (CCHFV) are present in Europe - lineage Europe 1 which contains pathogenic CCHFV strains, and lineage Europe 2 consisting of AP92 and AP92-like strains. In order to investigate CCHFV distribution and potential risk for humans, ticks were collected from livestock in the five districts where CCHF cases have been reported in the last five years in Bulgaria. CCHFV lineage Europe 1 was detected in 39 of 623 Hyalomma marginatum ticks (6.3%; range per village 2.7-15.2%), while CCHFV lineage Europe 2 was detected for the first time in Bulgaria in 49 of 415 Rhipicephalus sanguineus sensu lato ticks (11.8%; range 0-58.3%). The present study shows that both Europe 1 and Europe 2 CCHFV lineages are present in Bulgaria. The pathogenic role of the AP92-like strains remains to be elucidated. Copyright © 2016 Elsevier GmbH.

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.

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.

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.

The Early to Middle Triassic continental-marine transition of NW Bulgaria: sedimentology, palynology and sequence stratigraphy

2018-04-01

Sedimentary facies and cycles of the Triassic continental-marine transition of NW Bulgaria are documented in detail from reference sections along the Iskar river gorge between the villages of Tserovo and Opletnya. The depositional environments evolved from anastomosing and meandering river systems in the Petrohan Terrigenous Group to mixed fluvial and tidal settings in the Svidol Formation, and to peritidal and shallow-marine conditions in the Opletnya Member of the Mogila Formation. For the first time, the palynostratigraphic data presented here allow for dating the transitional interval and for the precise identification of a major sequence boundary between the Petrohan Terrigenous Group and the Svidol Formation (Iskar Carbonate Group). This boundary most probably corresponds to the major sequence boundary Ol4 occurring in the upper Olenekian of the Tethyan realm and thus enables interregional correlation. The identification of regionally traceable sequence boundaries based on biostratigraphic age control is a first step towards a more accurate stratigraphic correlation and palaeogeographic interpretation of the Early to early Middle Triassic in NW Bulgaria.

To search for optical variability on a wide range of timescales, we have carried out photometric monitoring of a dozen blazars. CCD magnitudes in B, V, R and I pass-bands were determined for > 10,000f new optical observations from 300 nights made during 2011 – 2016, with an average length of 4 h each, using seven optical telescopes: four in Bulgaria, one in Greece, and two in India. We measured multiband optical flux and colour variations on diverse timescales. Blazar variability studies helped us in understanding their nature and extreme conditions within the emission region. To explain possible physical causes of the observed spectral variability, we also investigated spectral energy distributions using B, V, R, I, J and K pass-band data.

The 12th International Symposium on Continuum Models and Discrete Systems (CMDS-12) (http://www.saha.ac.in/cmp/cmds.12/) took place at the Saha Institute of Nuclear Physics in Kolkata from 21-25 February 2011. Previous CMDS symposia were held in Kielce (Poland, 1975), Mont Gabriel (Canada, 1977), Freudenstadt (Federal Republic of Germany, 1979), Stockholm (Sweden, 1981), Nottingham (United Kingdom, 1985), Dijon (France, 1989), Paderborn (Germany, 1992), Varna (Bulgaria, 1995), Istanbul (Turkey, 1998), Shoresh (Israel, 2003) and Paris (France, 2007). The broad interdisciplinary character, limited number of participants (not exceeding 100) and informal and friendly atmosphere of these meetings has made them a well-acknowledged place to make highly fruitful contacts and exchange ideas, methods and results. The purpose of CMDS is to bring together scientists with different backgrounds who work on continuum theories of discrete mechanical and thermodynamical systems in the fields of mathematics, theoretical and applied mechanics, physics, material science, and engineering. The spirit of the CMDS meetings is to stimulate extensive and active interdisciplinary research. The International Scientific Committee members of this conference were: David J Bergman (Chairman CMDS 10), Tel Aviv University, Israel; Bikas K Chakrabarti (Chairman CMDS 12), Saha Institute of Nuclear Physics, India; Alex Hansen, Norwegian University of Science and Technology, Norway; Hans Jürgen Herrmann, Institute for Building Materials, ETH, Switzerland; Esin Inan (Chairman CMDS 9), Istanbul Technical University, Turkey; Dominique Jeulin (Chairman CMDS 11), Ecole des Mines de Paris, France; Frank Juelicher, Max-Planck-Institute for the Physics of Complex Systems, Germany; Hikaru Kawamura, University of Osaka, Japan; Graeme Milton, University of Utah, USA; Natalia Movchan, University of Liverpool, UK; and Ping Sheng, The Hong Kong University of Science and Technology, Hong Kong. At CMDS-12 the topics of interest were: Thermodynamics, transport theory and statistical mechanics in the context of continuum modeling discrete systems; Statistical mechanics and dynamics of fluid flows; Continuum mechanics of complex fluids and deformable solids with microstructure; Fundamentals of fracture, defect dynamics, fatigue, and fracture dynamics; Statics and dynamics of dislocations, dislocation mediated phase transitions and plasticity; Granular materials: statics and dynamics; Physics and mechanics of earthquakes; Transport in composite materials; and Continuum theory of soft matter systems of biological motivation and living structures. The scientific program consisted of General Lectures and Research Communications. The four General Lectures (40 min + 5 min) introduced the most recent ideas and advances in the fields covered. The 25 Research Communications reported new results and methods in these fields and were presented orally (30 min + 5 min). In addition there were 15 posters which also presented interesting results and five of these posters were selected by a special committee chaired by David J Bergman to contribute to this proceedings. The selected five posters were presented by Moutushi D Choudhury, Morten Grova, Arya Paul, Arnab Saha and Amartya Sarkar. We were happy to note that 32 scientists from ten countries and a large number of students (both from India and other countries) participated in this symposium.

Limited information is available to describe the molecular epidemiology of HIV-1 in Bulgaria. To better understand the genetic diversity and the epidemiologic dynamics of HIV-1 we analyzed 125 new polymerase (pol) sequences from Bulgarians diagnosed through 2009 and 77 pol sequences available from our previous study from persons infected prior to 2007. Epidemiologic and demographic information was obtained from each participant and phylogenetic analysis was used to infer HIV-1 evolutionary histories. 120 (59.5%) persons were infected with one of five different HIV-1 subtypes (A1, B, C, F1 and H) and 63 (31.2%) persons were infected with one of six different circulating recombinant forms (CRFs; 01_AE, 02_AG, 04_cpx, 05_DF, 14_BG, and 36_cpx). We also for the first time identified infection with two different clusters of unique A-like and F-like sub-subtype variants in 12 persons (5.9%) and seven unique recombinant forms (3.5%), including a novel J/C recombinant. While subtype B was the major genotype identified and was more prevalent in MSM and increased between 2000–2005, most non-B subtypes were present in persons ≥45 years old. CRF01_AE was the most common non-B subtype and was higher in women and IDUs relative to other risk groups combined. Our results show that HIV-1 infection in Bulgaria reflects the shifting distribution of genotypes coincident with the changing epidemiology of the HIV-1 epidemic among different risk groups. Our data support increased public health interventions targeting IDUs and MSM. Furthermore, the substantial and increasing HIV-1 genetic heterogeneity, combined with fluctuating infection dynamics, highlights the importance of sustained and expanded surveillance to prevent and control HIV-1 infection in Bulgaria.

In recent years, Bulgaria has increasingly relied on out-of-pocket payments as one of the main sources of health care financing. However, it is largely unknown whether the official patient charges, combined with informal payments, are affordable for the population. Our study aimed to explore the scale of out-of-pocket payments for health care services and their affordability. Data were collected in two nationally representative surveys, conducted in Bulgaria in 2010 and 2011, using face-to-face interviews based on a standardized questionnaire. To select respondents, a multi-stage random probability method was used. The questionnaire included questions on the out-of-pocket payments for health care services used by the respondent during the preceding 12 months. In total, 75.7% (2010) and 84.0% (2011) of outpatient service users reported to have paid out-of-pocket, with 12.6% (2010) and 9.7% (2011) of users reporting informal payments. Of those who had used inpatient services, 66.5% (2010) and 63.1% (2011) reported to have made out-of-pocket payments, with 31.8% (2010) and 18.3% (2011) reporting to have paid informally. We found large inability to pay indicated by the need to borrow money and/or forego services. Regression analysis showed that the inability to pay is especially pronounced among those with poor health status and chronic diseases and those on low household incomes. The high level of both formal and informal out-of-pocket payments for health care services in Bulgaria poses a considerable burden for households and undermines access to health services for poorer parts of the population.

The compensatory mechanisms of social security include expenses for sick leave. The aim of the study is to determine the economic cost due to sick leave among workers in wastewater treatment plants (WWTPs), comparing with the same economic indicators of the National Social Security Institute (NSSI) in Bulgaria. The sick leave of 111 workers at 3 WWTPs was studied in the period 2012-2014 on the grounds of registered absences from work due to temporary incapacity for work. The economic indicators of the NSSI, the gross salary at WWTPs, payable social security contributions and compensatory payments for sick leave have been used for economic cost calculation for temporary incapacity of the workers. The frequency of cases and the frequency of lost days due to temporary incapacity were increased in the observed period at WWTPs and in Bulgaria, and it is significantly higher for the employed at WWTPs. The percentage share of workers equivalent to 1.66% at WWTPs have not worked for an entire year as a result of temporary incapacity in 2012, 2.76% - in 2013, and 4.61% - in 2014. The economic burden due to sick leave at WWTPs was raised from EUR 4913.02 in 2012 to EUR 16 895.80 for 2014 for employers and the NSSI. The frequency of cases and the frequency of lost days due to temporary incapacity were increased in the observed period at WWTPs and in Bulgaria, and it is significantly higher for the employed at WWTPs. The economic burden was equally distributed between employers and the NSSI. Med Pr 2018;69(2):129-141. This work is available in Open Access model and licensed under a CC BY-NC 3.0 PL license.

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 purpose of this study was to present the impact of demography and market dynamics on the organizational and technological development of dental practices in Bulgaria during the period of socio-economic transition from 1990 to 2010. Relevant data were gathered from the official registers of the Bulgarian Dental Association, National Health Insurance Fund, National Health Information Institute and research studies, published during the period 1990-2010. They were analysed and are discussed in this paper. During the period there was a decrease in population of Bulgaria, from 8,149,468 in 2000 to 7,563,000 in 2010 and a movement from rural areas to cities. There was an aging population with an increase in oral health care needs at a time of decrease in the size of the national labour force and economic growth. Paradoxically, over the last 20 years, the number of dentists in Bulgaria increased by more than 50% from 1997 to 2008. The average age of dentists changed from 39.7 years in 1997 to 41.7 years in 2008. The number of group dental practices increased and the number of individual practices and group practices for specialized dental care and dental centres decreased. The utilization of dental services is currently "about half" that of the mean for all European Union Member States, which is over 80% per year. The growing number of elderly people who have retained their teeth suggests an increase in treatment needs. However, the decline in their purchasing power limits the demand for oral health care services. In order to meet this and other challenges Bulgarian dentists have started changing their traditional solo-practice to group-practice.

Background Glioblastoma multiforme (GBM) is a class IV astrocytic tumor, the most malignant of the four groups of World Health Organization (WHO) tumors with astrocytic differentiation. Aim The aim of this study was to estab­lish whether a correlation exists between the Ki-67 index of tumors with astrocytic differentiation, WHO grade, and patient survival. Materials and methods A retrospective non-clinical approach to patient selection was chosen for the aim of the study. A total of 47 patients diagnosed and treated for CNS tumors with astrocytic differentiation in the St. Marina University Hospital, Varna, Bulgaria, from September 2012 to July 2016 were retrospectively included into the study cohort. The cases were tested for their immunohistochemistry (IHC) reaction with Ki-67 after their original Hematoxylin and Eosin and IHC slides were reviewed by a single author and blind coded. The Ki-67 positivity index of the nuclei was estimated after digitalization of the slides and calculated by the ImmunoRatio automated count­ing tool. The individual Ki-67 index and patient survival of each case were statistically compared. Results The histopathological groups, after the blind Ki-67 index automated calculation was carried out, revealed no WHO grade I, two WHO grade II samples, four WHO grade III samples and 41 WHO grade IV cases, and these were included in the analysis. The two samples of WHO grade II astrocytic tumors had a mean Ki-67 index of 25%; however, they comprised tumors with an individual index of 43% and 7%, both individual values with a highly unlikely index for this group. The four samples of WHO grade III had a mean Ki-67 index of 4%, standard deviation ±2.16 (p>0.05), with the lowest index being 1% and the highest one being 6%. Both WHO grade II and III did not include enough samples to allow for a proper statistical analysis of patient survival. The 41 GBM cases had a mean Ki-67 index of 17.34%, standard deviation ±10.79 (p>0.05). Statistical analysis of the Ki-67 index divid­ed dichotomously into two groups and patient survival revealed that cases with a high Ki-67 index had no significant difference in survival when compared to those with low expression. Conclusions Based on the reported results, the mean Ki-67 percentage of positive nuclei in GBM tumor sam­ples cannot be used to estimate the survival of patients. However, Ki-67 remains a valuable IHC pathological tool. PMID:28845375

Excavating the Psyche: A Social History of Soviet Psychiatry in Bulgaria.

PubMed

Chehirian, Julian

2018-06-01

This article investigates how an imported Soviet psychiatric model affected Bulgarians who experienced psychological crisis by examining therapeutic possibilities that were available and foreclosed in the People's Republic of Bulgaria. Bulgarians struggling with psychological disorders in the present day experience polar forms of marginalization: non-recognition on one extreme, and chronic medicalization on the other. Both tendencies can be traced to the Communist-period remodeling of mental healthcare, which outlawed private practice and individual-centered therapy, which reified empirically observable, physiological underpinnings of pathology while suppressing therapies that engaged with the existential context of mental illness. I argue that the reproduction of a Soviet psychiatric model instigated a modernization process but failed to anticipate the idiosyncrasy of economic and social conditions within the country. Furthermore, that this model rejected a therapeutic focus on the individual but developed no effective alternative for identifying and treating subjective characteristics of mental illness. Bulgaria's history of psychiatry has received little scholarly attention beyond Bulgarian psychiatrists who documented the development of their field. This article presents archival, literary and oral history footholds towards the development of a social history of Bulgarian psychiatry-a perspective that is especially and problematically missing.

The social and institutional context of health-care reform in Eastern Europe has important implications for cervical cancer screening and prevention. The incidence and mortality from cervical cancer in Bulgaria and Romania have risen, which is in sharp contrast to the steady decline in most other countries in Europe during the last 2 decades. To analyze these dynamics we conducted a multi-component study of health systems and psychosocial aspects of cervical cancer screening in Bulgaria and Romania. Following the disappearance of organized preventive programs, the initiative for cervical cancer screening has shifted to providers and clients and depends on the way they perceive their responsibility and interpret their own and each other's roles in prevention. We focus on how providers construct women and their role in prevention of cervical cancer through their accounts. The analysis identified several discourses and themes in providers' constructions of women's responsibility for prevention of disease. These include responsible women as 'intelligent' and 'cultured'; non-attenders as 'irresponsible' and 'negligent'; women as needing monitoring and sanctioning; and women as 'victims' of health-care reform. We discuss the implications for health-care reform and health promotion.

Worldwide, approximately one in eight children or adolescents suffers from a mental disorder. The present study was designed to determine the self-reported prevalence of mental health problems in children aged 6-11 years across eight European countries including Italy, France, Germany, the Netherlands, Lithuania, Bulgaria, Romania, and Turkey. Data were drawn from 6245 children participating in the School Children Mental Health in Europe (SCHME) study and a large cross-sectional survey in France. Self-reported child mental health was assessed using the Dominique Interactive (DI). Overall, 22.0% of children were identified per their own evaluation as having at least one mental disorder, ranging from 16.4% in the Netherlands to 27.9% in Bulgaria. The prevalence of internalizing disorders was 18.4% across countries and ranged from 11.8% in the Netherlands to 24.3% in Turkey. The prevalence of externalizing disorders was lower with an average of 7.8%, ranging from 3.5% in Turkey to 10.5% in Bulgaria. Combining samples across European countries, 1 in 5 children reported internalizing problems and 1 in 12 children externalizing problems. The net completion rates of 4.1-74.3% preclude conclusions about national differences in prevalence rates.

ln Eastern European countries some industrial point sources are still suspected to have unacceptable emission rates of lead that pose a major health risk in particular to children. An interdisciplinary research project under the auspices of the EU had the aims (I) to monitor the current contamination of two industrial zones in Bulgaria and Poland, (2) to relate the Pb levels in ecological strata to the internal exposure of children, (3) to develop public health strategies in order to reduce the health risk by heavy metals. The human monitoring of Pb in Poland did not show increased health risks for the children living in an industrial zone close to Krakow. Bulgarian children, however, exceeded the WHO limit of 100 μg lead per litre blood by over one hundred percent (240 μg/1). Samples of soil, fodder and livestock organs showed elevated concentrations of lead. Recent literature results are compared with the findings in Bulgaria and Poland. The sources of the high internal exposure of children are discussed. Public health strategies to prevent mental dysfunction in Bulgarian children at risk include awareness building and social masures.

Water frog mating calls from two localities were studied and analyzed. Recordings were made in the summer of 2010 at the Arkutino swamp near the town of Primorsko and at the Vurbitza River near the town of Momchilgrad. A total of 154 calls were analyzed and the results suggested the presence of both the Marsh frog (Pelophylax ridibundus) and the Levant frog (Pelophylax bedriagae) in both sites, with the former being more frequent in Vurbitza River, and the latter - in Arkutino. At Vurbitza, we also captured and measured 2 specimens, which morphological characteristics differed from P. ridibundus and matched those of P. bedriagae. These are the first localities for P. bedriagae in Bulgaria.

To achieve high rates of waste reuse and recycling, waste separation in households is essential. This study aimed to reveal how recycling programmes in Sweden and Bulgaria influenced inhabitants' participation in separation of household waste. The waste separation behaviour of 111 university students from Kalmar, Sweden and 112 students from Plovdiv, Bulgaria was studied using the Theory of Planned Behaviour framework. The results showed that a lack of proper conditions for waste separation can prevent individuals from participating in this process, regardless of their positive attitudes. When respondents were satisfied with the local conditions for waste separation their behaviour instead depended on their personal attitudes towards waste separation and recycling.

This study investigates the importance of the effect of an individual's web of informal relationships with family and peers on the intention to have a second or third child. Drawing on sociological theories of social capital (help with childcare, emotional support) and social pressure, the study extends existing research by evaluating cross-national differences (between France, Germany, and Bulgaria) in the impact of personal network and institutional circumstances. It tests a non-linear relationship between social capital and fertility intentions. Social pressure and social capital are highly institutionally filtered, with the impact of personal network stronger where institutions are less family-supportive.

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.

The role of women in socialist Bulgaria is discussed with special emphasis on the changes in educational level and professional activity. In capitalist Bulgaria (prior to 1946), the vast majority of women (up to 90%) worked in textile, food or tobacco industry. Only 1.3% of women had a college degree. Socialist revolution in the post World War II Bulgaria gave women equal rights to employment and education. During the period of 1946-1975, there was a 14-fold increase in the number of women engaged in skilled labor. The number of women with college degrees showed progressive increases from 21.4% in 1956 to 47.7% in 1983. In 1977, 40.1% of research personnel and 31.9% of engineers were women. In 1965, approximately 75% of women in the 16-54 year age group were married; 81.3% of married women have been working. The number of married women with at least a high school diploma showed increases from 27.7% in 1965 to 37.7% in 1975, while the number of married women with vocational education increased from 4.7% to 12.4%. At the same time, the birth rate in working women showed a decrease from 2.03 in 1965 to 1.88 in 1975.

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 (" 113 RQKR↓F 117 "), 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.

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

While the impact of COPD in Western-Europe is known, data from Eastern-Europe is scarce. This study aimed to evaluate clinical characteristics, treatment patterns, and the socio-economic burden of COPD in Eastern-Europe, taking Bulgaria as a reference case. A representative sample of Bulgarian patients with COPD was randomly chosen by pulmonologists, based on the following inclusion criteria: COPD diagnosis with at least 1 year of living with COPD, ≥40 years of age, and use of COPD medication. Patient characteristics, treatment, quality-of-life, healthcare resource use, and costs were systematically assessed. A total of 426 COPD patients were enrolled. Approximately 69% were male, 40% had occupational risk factors, 45% had severe and 11% had very severe COPD. Mean CAT scores were 13.80 (GOLD A), 21.80 (GOLD B), 17.35 (GOLD C), and 26.70 (GOLD D). Annual per-patient costs of healthcare utilization were €579. Yearly pharmacotherapy costs were €693. Indirect costs (reduced and lost work productivity) outnumbered direct costs three times. Bulgaria has relatively high percentages of (very) severe COPD patients, resulting in considerable socio-economic burden. High smoking rates, occupational risk factors, air pollution, and a differential health system may be related to this finding. Eastern-European COPD strategies should focus on prevention, risk-factor awareness, and early detection.

To describe cataract surgical services in 1998 in 12 eastern European countries and to identify their needs to reduce cataract blindness. All inpatient eye departments in the 12 countries received a standardised questionnaire; the data obtained were further processed at the coordinating centre in Prague. All 458 eye departments in the region were involved. The response rate was 100%, except for Bulgaria (93%) and Romania (93%). The total number of cataract surgeries per one million inhabitants in 1998 was calculated: Belarus (800), Federation of Bosnia and Herzegovina (1275), Bulgaria (1730), the Czech Republic (4210), Estonia (2530), Hungary (3530), Latvia (1860), Lithuania (1550), Trans-Dniester Moldova (1300), Poland (1475), Romania (1260), and Slovakia (2430). Cataracts were mostly operated on by the extracapsular technique. Intracapsular extractions were frequently performed in Federation of Bosnia and Herzegovina (47%), Belarus (46%), Bulgaria (18%), and Romania (14.3%). Phacoemulsification was uncommonly used in 1998, except for the Czech Republic (86%), Estonia (50%), Slovakia (38%), and Hungary (16%). An IOL was implanted in more than 90% of patients in the Czech Republic, Estonia, Hungary, Latvia, Lithuania, and Slovakia. Conditions for cataract surgery in the eastern European region differ. The main barriers to cataract surgery were state budget limitations, insufficient supply of consumables, underutilisation of operating theatres, and poor detection of patients requiring surgery.

Reforming health care financing in Bulgaria: the population perspective.

PubMed

Balabanova, Dina; McKee, Martin

2004-02-01

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

Total Petroleum Systems of the Carpathian - Balkanian Basin Province of Romania and Bulgaria

2007-01-01

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 thermal maturation. Undiscovered resources in the Carpathian-Balkanian Basin Province are estimated, at the mean, to be 2,076 billion cubic feet of gas, 1,013 million barrels of oil, and 116 million barrels of natural gas liquids.

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 assessed.

Eastern Europe: pronatalist policies and private behavior.

PubMed

David, H P

1982-02-01

Fertility trends in the 9 Eastern European socialist countries (Albania, Bulgaria, Czechoslovakia, German Democratic Republic, Hungary, Poland, Romania, USSR, Yugoslavia) are reviewed. Official policy in all these countries but Yugoslavia is explicitly pronatalist to varying degrees. Attention is directed to the following areas: similarities and differences; fertility trends (historical trends, post World War 2 trends, and family size); abortion trends (abortion legislation history, current legislation, abortion data, impact on birth rates, abortion seekers, health risks, and psychological aftereffects); contraceptive availability and practice; pronatal economic incentives (impact on fertility); women's position; and marriage, divorce, and sexual attitudes. The fact that fertility was generally higher in the Eastern European socialist countries than in Western Europe in the mid-1970s is credited to pronatalist measures undertaken when fertility fell or threatened to fall below replacement level (2.1 births/woman) after abortion was liberalized in all countries but Albania, following the lead of the USSR in 1955. Fertility increased where access to abortion was again restricted (mildly in Bulgaria, Czechoslovakia, and Hungary at various times, and severely in Romania in 1966) and/or economic incentives such as birth grants, paid maternity leave, family and child care allowances, and low interest loans to newlyweds were substantially increased (Bulgaria, Czechoslovakia, Hungary, and Poland to some extent, in the late 1960s and early 1970s, and the German Democratic Republic in 1976). Subsequent declines in Bulgaria, Czechoslovakia, Hungary, and Romania suggest that policy induced increases in fertility are short-lived. Couples respond to abortion restrictions by practicing more efficient contraception or resorting to illegal abortion. It is evident that the region's low birth rate is realized mainly with abortion, for withdrawal remains the primary contraceptive method in all countries but Hungary and the German Democratic Republic. It seems that cash incentives have advanced the timing of 1st and 2nd births without substantially increasing the 3rd births required to keep national fertility above replacement level. Demographic factors alone will most likely keep birth rates low in several Eastern European countries during the 1980s and the 1990s. Due to the low birth rates in the 1960s, there will be fewer women in the prime childbearing ages of 20-29 in at least Poland, Czechoslovakia, Bulgaria, and Hungary. It becomes clear that policy efforts to influence private reproductive behavior can only be moderately successful if the living conditions are such that women are determined not to have more than 1 or 2 children.

This paper examines Bulgarian and American young adults' perceptions of prior experiences of intergenerational communication. Irrespective of culture, as age of target increased from young adult to middle-aged and elderly adult, so did attributions of benevolence, norms of politeness and deference, and communicative respect and avoidance; conversely, attributions of personal vitality and communication satisfaction decreased linearly. However, American youth reported more of a tendency to avoid, but expressed more respect when communicating with, older adults than their Bulgarian counterparts. In both settings, young adults' avoidant communication with older people negatively, and the norm of politeness positively, predicted intergenerational communication satisfaction. In Bulgaria only, age stereotypes also predicted communication satisfaction whereas only in the USA was communicative respect a predictor.

Mwuara Dept of Physics, Marshall University, Huntington, WV V. Pokropivny Institute for Materials Sciences of NASU, Kiev, Ukraine. D. Dimova-Malinovska Bulgarian Academy of Sciences, Sofia, Bulgaria. The dimensionality of a system has profound influence on its physical behavior. With advances in technology over the past few decades, it has become possible to fabricate and study reduced-dimensional systems, such as carbon nanotubes (CNTs). Carbon nanotubes are especially promising candidate for cold cathode field emitter because of their electrical properties, high aspect ratio, and small radius of curvature at the tips. Electron emission from the carbon nanotubes was investigated. Based upon the field emission investigation of carbon nanotubes, several prototype devices have been suggested that operate with low swing voltages with sufficient high current densities. Characteristics that allow improved current stability and long lifetime operation for electrical and opto-electronics devices are presented. The aim of this brief overview is to illustrate the useful characteristics of carbon nanotubes and its possible application.

The Space Environment Viewing and Analysis Network (SEVAN) aims to improve the fundamental research on particle acceleration in the vicinity of the sun, on space weather effects and on high-energy physics in the atmosphere and lightning initiation. This new type of a particle detector setup simultaneously measures fluxes of most species of secondary cosmic rays, thus being a powerful integrated device for exploration of solar modulation effects and electron acceleration in the thunderstorm atmosphere. The SEVAN modules are operating at the Aragats Space Environmental Center (ASEC) in Armenia, in Croatia, Bulgaria, Slovakia, the Czech Republic (from 2017) and in India. In this paper, we present the most interesting results of the SEVAN network operation during the last decade. We present this review on the occasion of the 10th anniversary of the International Heliophysical Year in 2007.

The First International Workshop and Summer School on Plasma Physics (IWSSPP'05) organized by The Faculty of Physics, University of Sofia and the Foundation `Theoretical and Computational Physics and Astrophysics' was dedicated to the World Year of Physics 2005 and held in Kiten, Bulgaria, on the Black Sea Coast, from 8--12 June 2005. The aim of the workshop was to bring together scientists from various branches of plasma physics in order to ensure an interdisciplinary exchange of views and initiate possible collaborations. Another important task was to stimulate the creation and support of a new generation of young scientists for the further development of plasma physics fundamentals and applications. This volume of Journal of Physics: Conference Series includes 31 papers (invited lectures, contributed talks and posters) devoted to various branches of plasma physics, among them fusion research, kinetics and transport phenomena in gas discharge plasmas, MHD waves and instabilities in the solar atmosphere, dc and microwave discharge modelling, plasma diagnostics, cross sections and rate constants of elementary processes, material processing, plasma-chemistry and technology. Some of them have been presented by internationally known and recognized specialists in their fields; others are Masters or PhD students' first steps in science. In both cases, we believe they will stimulate readers' interest. We would like to thank the members of both the International Advisory Committee and the Local Organizing Committee. We greatly appreciate the financial support from the sponsors: the Department for Language Teaching and International Students at Sofia University, Dr Ivan Bogorov Publishing house, and Artgraph2 Publishing house. We would like to express our gratitude to the invited lecturers who were willing to pay the participation fee. In this way, in addition to the intellectual support they provided by means of their excellent lectures, they also supported the school financially.

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.

PubMed Central

Kocur, I; Resnikoff, S; Foster, A

2002-01-01

Aim: To describe cataract surgical services in 1998 in 12 eastern European countries and to identify their needs to reduce cataract blindness. Methods: All inpatient eye departments in the 12 countries received a standardised questionnaire; the data obtained were further processed at the coordinating centre in Prague. Results: All 458 eye departments in the region were involved. The response rate was 100%, except for Bulgaria (93%) and Romania (93%). The total number of cataract surgeries per one million inhabitants in 1998 was calculated: Belarus (800), Federation of Bosnia and Herzegovina (1275), Bulgaria (1730), the Czech Republic (4210), Estonia (2530), Hungary (3530), Latvia (1860), Lithuania (1550), Trans-Dniester Moldova (1300), Poland (1475), Romania (1260), and Slovakia (2430). Cataracts were mostly operated on by the extracapsular technique. Intracapsular extractions were frequently performed in Federation of Bosnia and Herzegovina (47%), Belarus (46%), Bulgaria (18%), and Romania (14.3%). Phacoemulsification was uncommonly used in 1998, except for the Czech Republic (86%), Estonia (50%), Slovakia (38%), and Hungary (16%). An IOL was implanted in more than 90% of patients in the Czech Republic, Estonia, Hungary, Latvia, Lithuania, and Slovakia. Conclusions: Conditions for cataract surgery in the eastern European region differ. The main barriers to cataract surgery were state budget limitations, insufficient supply of consumables, underutilisation of operating theatres, and poor detection of patients requiring surgery.

We explore the hypothesis that the abrupt drainage of Laurentide lakes and associated rapid switch of the North Atlantic thermohaline circulation 8200 yr ago had a catastrophic influence on Neolithic civilisation in large parts of southeastern Europe, Anatolia, Cyprus, and the Near East. The event at 8200 cal yr BP is observed in a large number of high-resolution climate proxies in the Northern Hemisphere, and in many cases corresponds to markedly cold and arid conditions. We identify the relevant archaeological levels of major Neolithic settlements in Central Anatolia, Cyprus, Greece and Bulgaria, and examine published stratigraphic, architectural, cultural and geoarchaeological studies for these sites. The specific archaeological events and processes we observe at a number of these sites during the study interval 8400-8000 cal yr BP lead us to refine some previously established Neolithisation models. The introduction of farming to South-East Europe occurs in all study regions (Thrace, Macedonia, Thessaly, Bulgaria) near 8200 cal yr BP. We observe major disruptions of Neolithic cultures in the Levant, North Syria, South-East Anatolia, Central Anatolia and Cyprus, at the same time. We conclude that the 8200 cal yr BP aridity event triggered the spread of early farmers, by different routes, out of West Asia and the Near East into Greece and Bulgaria.

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.

Water pollution in the USSR and other Eastern European countries*

PubMed Central

Litvinov, N.

1962-01-01

The condition of water bodies and measures taken to prevent their pollution in the USSR, Czechoslovakia, Poland, Bulgaria and Romania are the main subjects of this paper. For each of these countries information is given on population and area, physical features, rain-fall and rivers, the distribution of population and industry, water supply and sewerage, the condition of surface and ground waters, the authorities and legislation concerned with the protection of water resources, and research on pollution. The author draws attention to the experience gained in these countries in the setting up of special State bodies to take charge of water resources and in classifying rivers according to the uses to which they are put, a factor which determines the regulations governing the discharge of effluent into them. A plea is also made for the convening of specialized international conferences on problems connected with the protection of European water resources from pollution. PMID:14465925

This paper details the construction of a 137Cs gamma calibration curve that has been established for dicentric assay and the testing and validation of the curve through biological dosimetry in three situations of suspected workplace overexposure that arose accidentally or through negligence or lack of appropriate safety measures. The three situations were: (1) suspected 137Cs contamination in a factory air supply; (2) suspected exposure to an industrial 192Ir source; and (3) accidental exposure of construction workers to radiation from a 60Co radiotherapy source in a hospital medical physics department. From a total of 24 potentially-exposed subjects, only one worker was found to have a statistically significant dose (0.16 Gy, 95% confidence intervals 0.02-0.43 Gy). In all other cases, the main function of the biological dosimetry was to reassure the subjects that any dose received was low.

2003-08-01

Despite their geographical, historical and cultural differences, Bulgaria and Italy share a surprisingly similar patrimony as regards the popular uses of medicinal plants. The extensive knowledge acquired over the centuries by people living in these countries and engaged in agriculture, derives from continuous contact with natural resources. This paper compares approximately 250 medicinal plants present in both countries and used in popular medicine. From this comparison it emerges that knowledge of medicinal plants and their uses are well founded. In fact, more than 80% of the plants are employed in identical or similar kinds of ailments, their preparation also showing marked similarities. The remaining 20% have very different uses, several of these being particularly noteworthy. The role played by edible plants, moreover, is important, about 30% being employed as medicine.

National roadmap for research infrastructure

In 2010 the Council of Ministers of Republic of Bulgaria passed a National roadmap for research infrastructure (Decision Num. 692 from 21.09.2010). Part of the roadmap is the project called Regional Astronomical Center for Research and Education (RACIO). Distinctive feature of this project is the integration of the existing in the country research and educational organizations in the field of astronomy. The project is a substantial part of the strategy for the development of astronomy in Bulgaria over the next decade. What is the content of this strategis project? How it was possible to include RACIO in the roadmap? Does the national roadmap charmonize with the strategic plans for the development of astronomy in Europe, elaborated by Astronet (http://www.astronet-eu.org/)? These are some of the questions which I try to give answers in this paper.

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.

Educational differences in all-cause mortality by marital status - Evidence from Bulgaria, Finland and the United States

Using life table measures, we compare educational differentials in all-cause mortality at ages 40 to 70 in Bulgaria to those in Finland and the United States. Specifically, we assess whether the relationship between education and mortality is modified by marital status. Although high education and being married are associated with lower mortality in all three countries, absolute educational differences tend to be smaller among married than unmarried individuals. Absolute differentials by education are largest for Bulgarian men, but in relative terms educational differences are smaller among Bulgarian men than in Finland and the U.S. Among women, Americans experience the largest education-mortality gradients in both relative and absolute terms. Our results indicate a particular need to tackle health hazards among poorly educated men in countries in transition. PMID:19165349

Isoenzymes are very suitable markers for the study of the inter-breed diversity of the silkworm Bombyx mon L. (Lepidoptera: Bombycidae). More than 250 breeds are raised in Bulgaria, which are not very well studied with regard to their isoenzymic polymorphism. Polymorphism of nonspecific esterases from pupal haemolymph was analyzed, as well as of phosphoglucomutase from different organs of larvae, pupae and imago, from eight introduced breeds. Electrophoresis in polyacrylamide gels was used. A polylocus control of nonspecific esterases, and possible monolocus control of phosphoglucomutase was ascertained. Biallele and triallele polymorphism of phosphoglucomutase locus and in three of the esterase loci was determined. The allelic frequencies of the polymorphic loci in each breed were analyzed. Inter-breed differences were found in different allelic frequencies, different heterozygosity and polymorphism.

An historical overview of the activities in the field of exposure and risk assessment of non-ionizing radiation in Bulgaria.

PubMed

Israel, Michel

2015-09-01

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.

Safety Assessment for the Kozloduy National Disposal Facility in Bulgaria - 13507

2013-07-01

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 Assessmentmore » 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.

Organisation and financing of the health care systems of Bulgaria and Greece – what are the parallels?

PubMed Central

Exadaktylos, Nikolaos M

2005-01-01

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

Although cystic echinococcosis (CE) is highly endemic in Bulgaria, there is still scarce information about species and/or genotypes of the Echinococcus granulosus complex that infect humans. Our study tackled the genetic diversity of E. granulosus complex in a cohort of 30 Bulgarian CE patients. Ten animal E. granulosus isolates from neighboring Greece were additionally included. Specimens were comparatively analyzed for partial sequences of five mitochondrial (mt) (cox I, nad I, rrnS, rrnL, and atp6) and three nuclear (nc) genes (act II, hbx 2, and ef-1α) using a PCR-sequencing approach. All 30 Bulgarian isolates were identified as E. granulosus sensu stricto (s.s.) and were showing identical sequences for each of the three examined partial nc gene markers. Based upon concatenated sequences from partial mtDNA markers, we detected 10 haplotypes: 6 haplotypes (H1-H6) clustering with E. granulosus s.s. (G1) and 4 haplotypes (H9-H13) grouping with E. granulosus s.s. (G3), with H1 and H10 being the most frequent in Bulgarian patients. The haplotypes H1, H4, and H11 were also present in Greek hydatid cyst samples of animal origin. In conclusion, E. granulosus s.s. (G1 and G3 genotypes) is the only causative agent found so far to cause human CE in Bulgaria. However, further studies including larger sample sizes and other additional geographic regions in Bulgaria will have to be performed to confirm our results.

This volume of Journal of Physics: Conference Series contains the Proceedings of the 5th International Symposium in Quantum Theory and Symmetries (QTS5), held in Valladolid, Spain, 22-28 July 2007. This is the fifth of a series of conferences previously held in Goslar (Germany) 1999, QTS1; Cracow (Poland) 2001, QTS2; Cincinnati (USA) 2003, QTS3, and Varna (Bulgaria) 2005, QTS4. The QTS5 symposium gathered 181 participants from 39 countries working in different fields on Theoretical Physics. The spirit of the QTS conference series is to join researchers in a wide variety of topics in Theoretical Physics, as a way to make accessible recent results and the new lines of different fields. The QTS5 conference offered the following list of topics: Symmetries in String Theory, Quantum Gravity and related Symmetries in Quantum Field Theories, Conformal and Related Field Theories, Lattice and Noncommutative Theories, Gauge Theories Quantum Computing, Information and Control Foundations of Quantum Theory Quantum Optics, Coherent States, Wigner Functions Dynamical and Integrable Systems Symmetries in Condensed Matter and Statistical Physics Symmetries in Particle Physics, Nuclear, Atomic and Molecular Nonlinear Quantum Mechanics Time Asymmetric Quantum Mechanics SUSY Quantum Mechanics, PT symmetries and pseudo-Hamiltonians Mathematical Methods for Symmetries and Quantum Theories Symmetries in Chemistry Biology and other Sciences Papers accepted for publication in the present issue are based on the contributions from the participants in the QTS5 conference after a peer review process. In addition, a special issue of Journal Physics A: Mathematical and Theoretical contains contributions from plenary speakers, some participants as well as contributions from other authors whose works fit into the topics of the conference. The organization of the conference had the following pattern. In the morning there were five plenary or general sessions for all the participants, which aimed to give a state of the art view of different topics. The afternoon was devoted to 6 parallel sessions, each one including the most afine topics. Also there was a poster session that could be visited in the intermediates and during the coffe breaks. A total of 23 plenary conferences, 130 parallel communications and 25 posters were presented in QTS5. All the sessions were given in the Palace of Conferences Conde Ansúrez which among other facilities also had a computer room. As social activities we had a guided walk around the historical part of the city, a visit to the nearby city of Segovia, as well as a welcome party and farewell dinner. These activities were intended to foster contact and informal discussions among the participants in the meeting. We are much indebted to several institutions that without their support the organization of the QTS5 symposium would not have been possible. In this respect we greatly acknowledge to Ministerio de Educación of Spain and Junta de Castilla y León for general financial support, to Fundación Universidades de Castilla y León for a number of grants to young researchers who otherwise would not have attended the conference, to the European Physical Society that provided a number of grants for eastern countries and to the University of Valladolid where the event took place. We want to thank all the members of the Conference Board and the International Advisory Committee of QTS5 for honoring us with their help and support. Here we must mention our gratitude to the other members of the Local Organizing Committe of QTS5, Manuel Gadella, José Manuel Izquierdo and Sengül Kuru, who are not Editors of this JPCS issue but shared with us the complex organization of this event. We acknowledge IOP Publishing for the facilities in the publication of these Proceedings. Finally, on behalf of the Local Organizing Committee, we would like to thank all the participants in the QTS5 conference for their presence, contributions, and for the good atmosphere achieved during their stay. We hope that the experience of spending these days in Valladolid has been most fruitful for all of them.

Background: Schools are important settings for the promotion of a healthy diet and sufficient physical activity and thus overweight prevention. Objective: To assess differences in school nutrition environment and body mass index (BMI) in primary schools between and within 12 European countries. Methods: Data from the World Health Organization (WHO) European Childhood Obesity Surveillance Initiative (COSI) were used (1831 and 2045 schools in 2007/2008 and 2009/2010, respectively). School personnel provided information on 18 school environmental characteristics on nutrition and physical activity. A school nutrition environment score was calculated using five nutrition-related characteristics whereby higher scores correspond to higher support for a healthy school nutrition environment. Trained field workers measured children’s weight and height; BMI-for-age (BMI/A) Z-scores were computed using the 2007 WHO growth reference and, for each school, the mean of the children’s BMI/A Z-scores was calculated. Results: Large between-country differences were found in the availability of food items on the premises (e.g., fresh fruit could be obtained in 12%−95% of schools) and school nutrition environment scores (range: 0.30−0.93). Low-score countries (Bulgaria, Czech Republic, Greece, Hungary, Latvia and Lithuania) graded less than three characteristics as supportive. High-score (≥0.70) countries were Ireland, Malta, Norway, Portugal, Slovenia and Sweden. The combined absence of cold drinks containing sugar, sweet snacks and salted snacks were more observed in high-score countries than in low-score countries. Largest within-country school nutrition environment scores were found in Bulgaria, Czech Republic, Greece, Hungary, Latvia and Lithuania. All country-level BMI/A Z-scores were positive (range: 0.20−1.02), indicating higher BMI values than the 2007 WHO growth reference. With the exception of Norway and Sweden, a country-specific association between the school nutrition environment score and the school BMI/A Z-score was not observed. Conclusions: Some European countries have implemented more school policies that are supportive to a healthy nutrition environment than others. However, most countries with low school nutrition environment scores also host schools with supportive school environment policies, suggesting that a uniform school policy to tackle the “unhealthy” school nutrition environment has not been implemented at the same level throughout a country and may underline the need for harmonized school policies.

The requirements for quality control (QC) in diagnostic radiology were introduced in Bulgarian legislation in 2005. Hospital medical physicists and several private medical physics groups provide QC services to radiology departments. The aim of this study was to analyse data from QC tests in mammography and to investigate the impact of QC introduction on mammography practice in the country. The study was coordinated by the National Centre of Radiobiology and Radiation Protection. All medical physics services were requested to fill in standardised forms with information about most important parameters routinely measured during QC. All QC service providers responded. Results demonstrated significant improvement of practice since the introduction of QC, with reduction of established deviations from 65 % during the first year to 7 % in the last year. The systems that do not meet the acceptability criteria were suspended from use. Performance of automatic exposure control and digital detectors are not regularly tested because of the absence of requirements in the legislation. The need of updated guidance and training of medical physicists to reflect the change in technology was demonstrated. © The Author 2015. Published by Oxford University Press. All rights reserved.

The scientific information is the latest and one of the best bedrock on which effective policy to combat and cope with natural disasters have to be built. Understanding, monitoring and information for future natural disasters are the way to assist the government and society. Different types of networks provide reliable information on various natural disasters. For example, one of the main priorities of the networks are directed to study seismicity of the Earth, its physical phenomena and fields - with an emphasis on tectonic movements and related risk processes, global changes, rotation and position of the Earth in space. Therefore seismological network using advanced electronic systems and digital seismographs transmission of signals from seismic stations to the centres and the registration, processing and archiving of information is carried out by a specialized computer system. Thus improve the monitoring and analysis of seismicity in the whole plan. Another type networks as permanent GPS/GNSS networks are associated with processing and data analysis, as well as monitoring of recent movements of the earth crust. In this study we focus on Seismological and GPS/GNSS networks on the territory in Bulgaria. At present NIGGG-BAS runs both Bulgarian seismological and GPS/GNSS networks. The Bulgarian seismological network - NOTSSI (National Operative Telemetric System for Seismological Information) was founded at the end of 1980. The network comprises today 15 permanent seismic stations spanning the entire territory of the country and two local net works that are deployed around the town of Provadia and Kozloduy Nuclear Power Plant in Bulgaria. Since 2005-2006, real-time data exchange between Bulgaria and Greece, Romania, Serbia, Macedonia, Slovakia, Slovenia, Austria and other regional and national seismological data centers was implemented. NIGGG, respectively NOTSSI, is responsible for rapid earthquake determination, public information trough media, and information of responsible governmental authorities if necessary urgent activities to be undertaken. The available infrastructure - permanent GNSS stations, spread all over the country allow performing permanent monitoring of the Earth's crust movements on the basis of the obtained velocities of the permanent stations and the time series with their coordinates. Additional information for the current movements is obtained by the processing and analysis of the regular GNSS measurements of geodynamic network. In the GNSS Analysis Center are acquired, processed and analyzed data from more than 70 permanent stations on Bulgarian territory. In the analysis are included also data from permanent stations on the Balkan Peninsula and from the European Permanent Network. Along with the seismological and geological information, the quantitative assessment of the movements of the Earth's crust is of the substantial importance for monitoring of the active tectonic structures and is the base for the seismic hazard assessment.

To estimate the budget impact of the introduction of biosimilar infliximab for the treatment of Crohn's disease (CD) in Bulgaria, the Czech Republic, Hungary, Poland, Romania and Slovakia. A 3-year, prevalence-based budget impact analysis for biosimilar infliximab to treat CD was developed from third-party payers' perspective. The model included various scenarios depending on whether interchanging originator infliximab with biosimilar infliximab was allowed or not. Total cost savings achieved in biosimilar scenario 1 (interchanging not allowed) and BSc2 (interchanging allowed in 80% of the patients) were estimated to €8.0 million and €16.9 million in the six countries. Budget savings may cover the biosimilar infliximab therapy for 722-1530 additional CD patients. Introduction of biosimilar infliximab to treat CD may offset the inequity in access to biological therapy for CD between Central and Eastern European countries.

Potassic syenites from Svidnya, Bulgaria crop out as small isolated bodies as the primary for this intrusion liquid has basic to intermediate composition. The evolution in a closed magma chamber created plutonic rocks ranging from basic (melasyenite) to acid (granite) and from metaluminous to peralkaline. The most mafic varieties show cumulative textures typical for orthocumulates with cumulus phases clinopyroxene, biotite, apatite and potassium feldspar as gravitational settling is a viable process for separation of particles in the bottom parts of magma chamber. In the middle stratigraphic level of biggest body modal igneous layering with development of dark (clinopyroxene + amphibole) and light (potassium feldspar) laminas was observed. Oscillatory crystallization around eutectic point resulted in cyclic separation of mafic and felsic phases in repetitive layers. Fractionation of Ca- and Al-rich phases—clinopyroxene, biotie and potassium feldspar created peralkaline residual liquid strongly enriched in HFS elements.

Current healthcare in Bulgaria: time for predictive diagnostics and preventive medicine.

Dimitrov, Dimiter V

2010-12-01

Since 1990 Bulgaria gradually moved from monopolistic to market regulated economy and healthcare. In 2007 the country became member of the European Union and started to adopt EU legislations. However, significant gaps between the average European and Bulgarian level of social, health and economic efficiency remain to be narrowed. The major challenge is the demographic situation, where recent trends give alarming signals. Plans for reformation include transition towards out-patient palliative healthcare centers for the aging population as well as reduction of the costs with new electronic system of health insurance. The favorable location of the country at the Black Sea coast gives opportunities for medical tourism, which can provide quality health service for foreign customers. Finally, national platforms on prevention of major non-communicable diseases, such as obesity, cancer and diabetes, must be established as coordinated actions for the health and wellness of next generations.

Water management in the framework of environmental management systems in Bulgarian seaports

NASA Astrophysics Data System (ADS)

Quynh, Le Xuan; Hens, Luc; Stoyanov, Stoyan

Seaports or harbours are major hub of economic activities, connecting sea routes with the hinterland via rail, road and inland waterway. At the same time, they are hubs of environmental issues, resulting from its diversified operations involving vessels, machines, vehicles and industries. The Black Sea Commission in 2007 pointed out that water pollution at the ports around Black Sea, including the ports of Bourgas and Varna, poses a great threat to the overall water quality of the Black Sea and the quality of the Mediterranean Sea. The two ports, and their facilities, are the black spots of pollution that need immediate intervention to safeguard the Black Sea. The first steps of an environmental management system were implemented at both ports. Environmental protection objectives are identified and initial actions are being implemented. However, assessment of the environmental performance of both ports based on concrete indicators was not done. Further efforts are needed to advance the environmental management system to contribute more to the protection of the Mediterranean and Black Sea region.

Can genetics help us understand Indian social history?

PubMed

Thapar, Romila

2014-06-26

Attempts have been made recently to determine the identity of the so-called "Aryans" as components of the Indian population by using DNA analysis. This is largely to ascertain whether they were indigenous to India or were foreign arrivals. Similar attempts have been made to trace the origins of caste groups on the basis of varna identities and record their distribution. The results so far have been contradictory and, therefore, not of much help to social historians. There are problems in the defining of categories and the techniques of analysis. Aryan is a linguistic and cultural category and not a biological one. Caste groups have no well-defined and invariable boundaries despite marriage codes. Various other categories have been assimilated into particular castes as part of the evolution of social history on the subcontinent. A few examples of these are discussed. The problems with using DNA analysis are also touched on. Copyright © 2014 Cold Spring Harbor Laboratory Press; all rights reserved.

Cultural context, obsessive-compulsive disorder symptoms, and cognitions: a preliminary study of three Turkish samples living in different countries.

PubMed

Yorulmaz, Orçun; Işık, Bilgen

2011-04-01

Previous research findings have suggested that recent cognitive accounts of obsessive-compulsive disorder (OCD) are valid across different cultural contexts for both clinical and nonclinical samples; however, there is evidence that cultural differences may have an impact on a number of cognitive variables. For this reason, immigration provides an exceptional opportunity for an examination of the role of cultural context in cognitions and possible changes in cultural characteristics. To this end, the present study examined the interrelationships between thought-action fusion, thought control strategies and OCD symptoms in three nonclinical samples, taking the immigration factor into consideration. Thus, the current study included three Turkish sample groups: those who remigrated to Turkey from Bulgaria, those still living in Bulgaria, and those that have always resided in Turkey. The findings of the study supported the role of thought and action fusion and control strategies in OCD symptoms in a cross-cultural context. To illustrate, worry, as a thought control strategy for OCD symptoms, was a common factor in all three sample groups. However, differences were also noted between the groups, despite having the same ethnic origin. Although they immigrated back to Turkey and have been living there for a considerable period of time, the Turkish remigrants retained similar characteristics to the respondents in Bulgaria on cognitions in general. Consequently, it may be suggested that cultural context might have a relative impact on certain correlates. A replication of these findings using different immigration groups and examining various cultural factors is strongly encouraged.

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. 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. 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%). 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.

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

Space weather and myocardial infarction diseases at subauroral latitudes

NASA Astrophysics Data System (ADS)

Samsonov, Sergey; Kleimenova, Natalia; Petrova, Palmira

The relationship of the number of calls for the emergency medical care in Yakutsk (subauroral latitudes) in connection with myocardial infarction diseases during years near the maximum (1992) and minimum (1998) of the 11-year geomagnetic disturbance cycle to space weather parameters has been studied. It is found that at subauroral latitudes, the increase of geomagnetic activity, namely, the occurrence of night magnetospheric substorms, plays the important role in the exacerbation of myocardial infarctions. Substorms are accompanied by Pi1 irregular geomagnetic pulsations with periods of (0.5-3.0) Hz, coinciding with heart rhythms of a human being, thus, these waves can be a biotropic factor negatively influencing on the occurrence of myocardial infarctions. The comparison of seasonal change of the number of calls for emergency medical care to patients at subauroral latitudes with a simultaneous seasonal change of fatal endings because of an infarction at low latitudes (Bulgaria) has shown their essential difference. Thus, in Bulgaria the maximum of infarctions have been marked in winter, and minimum - in summer, and in Yakutsk a few maxima coinciding with the sharp and considerable increases of the level of the planetary geomagnetic disturbances have been observed. In this case, in Bulgaria the infarctions could be connected with availability of the Pc1 geomagnetic pulsations. Thus, the stable quasi-sinusoidal Pc1 pulsations can be a biotropic factor influencing on the development of myocardial infarctions at middle latitudes and the Pi1 irregular geomagnetic pulsations, which do not propagate to the lower latitudes, could be a biotropic factor at subauroral latitudes.

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.

Lowered work engagement and burnout are a growing problem in recent years, especially among physicians. Cynicism, lack of energy and decreased efficacy may lead to the occurrence of severe depression. These phenomena influence almost every aspect of affected person's life, both professional and extraprofessional, and decrease its quality. The aim of our study was to evaluate the influence of family life and other factors on levels of work engagement and risk of depression. Our study was conducted on a group of 417 physicians from Poland, Serbia and Bulgaria using a paper questionnaire. The collected data was subjected to statistical analyses using Statsoft Statistica v. 10.0 software. There was no significant correlation between work engagement and sex or age. The highest score on work engagement was in Serbia (m=4.41; Mann-Whitney's U test with p<0.05). The highest score of BDI was in Bulgaria (m=14.73; Mann-Whitney's U test with p<0.05). There was no significant correlation exceeding r=0.5 between UWES and SWING scales. WHI+/WHI- ratio correlates significantly with a BDI scale (Spearman's r=-0.49; p<0.05). Family life of physicians seem to have minor or even no influence on their work engagement and risk of burnout. The negative influence of work on family life may increase the risk of depression, and that effect is not susceptible to either positive or negative interactions of family life with work. The country with the lowest expenditure on a healthcare have also the lowest levels of work engagement.

Two new high-altitude subspecies of Tapinopterus (Tapinopterus) cognatus (Dejean, 1831) (Coleoptera: Carabidae: Pterostichinae) from Serbia.

PubMed

The genus Tapinopterus Schaum, 1858 currently comprises around 60 species belonging to eight subgenera, inhabiting mostly the Balkan Peninsula and Asia Minor (Schatzmayr 1942, 1943; Bousquet 2003; Ćurčić et al. 2008; Arndt et al. 2011; Lohaj et al. 2012). The taxa live in limited geographic areas and are mostly montane (Trautner & Geigenmüller 1987; Guéorguiev & Guéorguiev 1998). The territory of Serbia is inhabited by two species of Tapinopterus, T. (T.) cognatus (Dejean, 1831) (recorded in Bulgaria and Romania as well) and T. (T.) miridita (Apfelbeck, 1904) (recorded in Albania and the Republic of Macedonia as well), as well as by the three subspecies, T. (T.) cognatus cognatus (Dejean, 1831) (known from Mt. Suva Planina in Serbia and from Bulgaria), T. (T.) cognatus winkleri Mandl, 1936 (known from the Svrljiške Planine Mts. and Mt. Stara Planina in both Serbia and Bulgaria), and T. (T.) miridita miridita (Apfelbeck, 1904) (known from Mt. Šar Planina in both Serbia and the Republic of Macedonia), respectively (Mandl 1936; Schatzmayr 1942, 1943; Guéorguiev & Guéorguiev 1995; Drovenik & Peks 1999; Bousquet 2003; Ćurčić et al. 2007; Guéorguiev & Giachino 2008). In our opinion, T. (T.) cognatus cognatus does not live in Bulgaria (as was previously reported) (Bousquet 2003), while the older Schatzmayr's (1943) record "Klisura" should refer to the Iron Gate Gorge in SW Romania and NE Serbia, not to any Bulgarian place. The other mentioned locality, i.e., Mt. Suva Planina in Serbia, is situated far from the type locality (Iron Gate). Since nearly all Tapinopterus taxa are regional or local endemics, this southernmost record in SE Serbia for T. cognatus cognatus seems unlikely. In view of the high diversity of Tapinopterus on the Balkan Peninsula, it is expected that new taxa exist in border areas of the distribution in Serbia. During the last years, the first (SĆ), second (NI) and fourth author (DA) of the paper investigated a number of epigean montane habitats in SE and C Serbia in order to confirm such an assumption, by collecting a series of ground beetles at high altitude sites. After careful examination of the samples, we identified two Tapinopterus subspecies new to science.

To better define the structure and origin of the Bulgarian paternal gene pool, we have examined the Y-chromosome variation in 808 Bulgarian males. The analysis was performed by high-resolution genotyping of biallelic markers and by analyzing the STR variation within the most informative haplogroups. We found that the Y-chromosome gene pool in modern Bulgarians is primarily represented by Western Eurasian haplogroups with ∼ 40% belonging to haplogroups E-V13 and I-M423, and 20% to R-M17. Haplogroups common in the Middle East (J and G) and in South Western Asia (R-L23*) occur at frequencies of 19% and 5%, respectively. Haplogroups C, N and Q, distinctive for Altaic and Central Asian Turkic-speaking populations, occur at the negligible frequency of only 1.5%. Principal Component analyses group Bulgarians with European populations, apart from Central Asian Turkic-speaking groups and South Western Asia populations. Within the country, the genetic variation is structured in Western, Central and Eastern Bulgaria indicating that the Balkan Mountains have been permeable to human movements. The lineage analysis provided the following interesting results: (i) R-L23* is present in Eastern Bulgaria since the post glacial period; (ii) haplogroup E-V13 has a Mesolithic age in Bulgaria from where it expanded after the arrival of farming; (iii) haplogroup J-M241 probably reflects the Neolithic westward expansion of farmers from the earliest sites along the Black Sea. On the whole, in light of the most recent historical studies, which indicate a substantial proto-Bulgarian input to the contemporary Bulgarian people, our data suggest that a common paternal ancestry between the proto-Bulgarians and the Altaic and Central Asian Turkic-speaking populations either did not exist or was negligible.

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. © 2015 The Authors.

Limited data on smoking prevalence allowing valid between-country comparison are available in Europe. The aim of this study is to provide data on smoking prevalence and its determinants in 18 European countries. In 2010, within the Pricing Policies And Control of Tobacco in Europe (PPACTE) project, we conducted a face-to-face survey on smoking in 18 European countries (Albania, Austria, Bulgaria, Czech Republic, Croatia, England, Finland, France, Greece, Hungary, Ireland, Italy, Latvia, Poland, Portugal, Romania, Spain and Sweden) on a total of 18 056 participants, representative for each country of the population aged 15 years or older. Overall, 27.2% of the participants were current smokers (30.6% of men and 24.1% of women). Smoking prevalence was highest in Bulgaria (40.9%) and Greece (38.9%) and lowest in Italy (22.0%) and Sweden (16.3%). Smoking prevalence ranged between 15.7% (Sweden) and 44.3% (Bulgaria) for men and between 11.6% (Albania) and 38.1% (Ireland) for women. Multivariate analysis showed a significant inverse trend between smoking prevalence and the level of education in both sexes. Male-to-female smoking prevalence ratios ranged from 0.85 in Spain to 3.47 in Albania and current-to-ex prevalence ratios ranged from 0.68 in Sweden to 4.28 in Albania. There are considerable differences across Europe in smoking prevalence, and male-to-female and current-to-ex smoking prevalence ratios. Eastern European countries, lower income countries and those with less advanced tobacco control policies have less favourable smoking patterns and are at an earlier stage of the tobacco epidemic.

Biological drugs opened up new horizons in the management of inflammatory bowel diseases (IBD). This study focuses on access to biological therapy in IBD patients across 9 selected Central and Eastern European (CEE) countries, namely Bulgaria, the Czech Republic, Estonia, Hungary, Latvia, Lithuania, Poland, Romania and Slovakia. Literature data on the epidemiology and disease burden of IBD in CEE countries was systematically reviewed. Moreover, we provide an estimation on prevalence of IBD as well as biological treatment rates. In all countries with the exception of Romania, lower biological treatment rates were observed in ulcerative colitis (UC) compared to Crohn’s disease despite the higher prevalence of UC. Great heterogeneity (up to 96-fold) was found in access to biologicals across the CEE countries. Poland, Bulgaria, Romania and the Baltic States are lagging behind Hungary, Slovakia and the Czech Republic in their access to biologicals. Variations of reimbursement policy may be one of the factors explaining the differences to a certain extent in Bulgaria, Latvia, Lithuania, and Poland, but association with other possible determinants (differences in prevalence and incidence, price of biologicals, total expenditure on health, geographical access, and cost-effectiveness results) was not proven. We assume, nevertheless, that health deterioration linked to IBD might be valued differently against other systemic inflammatory conditions in distinct countries and which may contribute to the immense diversity in the utilization of biological drugs for IBD. In conclusion, access to biologicals varies widely among CEE countries and this difference cannot be explained by epidemiological factors, drug prices or total health expenditure. Changes in reimbursement policy could contribute to better access to biologicals in some countries. PMID:25684937

An innovative approach to teaching bioethics in management of healthcare.

Aleksandrova-Yankulovska, Silviya

2016-03-01

Bioethical courses were introduced in the curricula in medical universities in Bulgaria in 1990s. In the beginning, the courses were mainly theoretical, and systematic case analyses and discussions of movies were introduced later on. The benefits of using films to teach ethics have been previously analyzed in the literature; however, to our knowledge such studies in Bulgaria are yet lacking. The aim of this study was to survey the opinions of students and analyze the results from the application of movies in bioethics teaching in a medical university in the north of Bulgaria. A survey was carried out among 92 students in the management of healthcare. Two movies were used, and separate protocols for film discussion were developed. The study was conducted anonymously and with students' free informed consent. The students distinguished in total 21 different dilemmas and concepts in the first movie. The ethical dilemmas were classified into five groups: general ethical issues, deontological issues, special ethical issues, principles of bioethics, and theories of ethics. The second movie focused students' attention on the issues of death and dying. In total, 18 elements of palliative care were described by the students. The range of different categories was a positive indicator of an increased ethical sensitivity. The students evaluated the movies' discussions as a generally positive educational approach. They perceived the experience as contributing to their better understanding of bioethical issues. The innovative approach was well accepted by the students. The introduction of movies in the courses of bioethics had the potential to provide vivid illustrations of bioethical issues and to contribute to the exploration of specific theses and arguments. The presentation and discussion should be preceded by accumulation of theoretical knowledge. The future of effective bioethics education lays in the interactive involvement of students. © The Author(s) 2014.

Abstract The purpose of this study was to analyze sequences of hepatitis A virus (HAV) Ia and Ib genotypes from Bulgarian patients to investigate the molecular epidemiology of HAV genotype I during the years 2012 to 2014. Around 105 serum samples were collected by the Department of Virology of the National Center of Infectious and Parasitic Diseases in Bulgaria. The sequenced region encompassed the VP1/2A region of HAV genome. The sequences obtained from the samples were 103. For the phylogenetic analyses, 5 datasets were built to investigate the viral gene in/out flow among distinct HAV subpopulations in different geographic areas and to build a Bayesian dated tree, Bayesian phylogenetic and migration pattern analyses were performed. HAV Ib Bulgarian sequences mostly grouped into a single clade. This indicates that the Bulgarian epidemic is partially compartmentalized. It originated from a limited number of viruses and then spread through fecal-oral local transmission. HAV Ia Bulgarian sequences were intermixed with European sequences, suggesting that an Ia epidemic is not restricted to Bulgaria but can affect other European countries. The time-scaled phylogeny reconstruction showed the root of the tree dating in 2008 for genotype Ib and in 1999 for genotype Ia with a second epidemic entrance in 2003. The Bayesian skyline plot for genotype Ib showed a slow but continuous growth, sustained by fecal-oral route transmission. For genotype Ia, there was an exponential growth followed by a plateau, which suggests better infection control. Bidirectional viral flow for Ib genotype, involving different Bulgarian areas, was observed, whereas a unidirectional flow from Sofia to Ihtiman for genotype Ia was highlighted, suggesting the fecal-oral transmission route for Ia.

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.

A 650-year record of past summer temperatures from Pirin, Bulgaria tree-ring density

2017-12-01

New proxy records of past climate provide valuable data essential to enhance spatial and temporal coverage of the global paleoclimate record - the context against which ongoing climate change and climate-model forcing is examined and evaluated. We present a new 650-year record of past summer temperatures in southeastern (SE) Europe derived from tree-ring maximum-latewood-density (MXD) data measured from Bosnian pine (Pinus heldreichii) growing at high elevations in the Pirin Mountains, Bulgaria (PRN). The PRN collection is well-replicated, with 64 trees contributing MXD series ranging in length from 113 to 865 years (median series length = 480 years) spanning the years 1143-2009. The PRN chronology shows a significant (p < 0.05) relationship with summer (JAS) temperatures across a broad geographical area of SE Europe, including the entire Balkan peninsula, southern Italy, and southwestern Anatolia. Our temperature reconstruction, produced by multiple regression utilizing lagged predictors and calibrated against Sofia, Bulgaria meteorological observations, explains nearly 60% of target variance and reveals variability across decadal, centennial, and longer timescales over the 1350-2009 reconstruction interval. Relative to the instrumental 1900-1980 mean, our record shows multidecadal cool anomalies spanning the first half of the 19th century and the late 17th century, and warm periods spanning the 18th century, 16th and early-to-mid 17th centuries, and late 14th to early 15th century. A comparison of the PRN reconstruction with existing reconstructions of Northern Hemisphere temperatures reveal intervals of asynchrony between local and hemisphere-scale decadal temperature variability, with marked asynchrony in the late 16th-early 17th centuries, and unprecedented asynchrony in the late 20th-to early 21st century.

Environmental Kuznets curve for EU agriculture: empirical evidence from new entrant EU countries.

PubMed

Zafeiriou, Eleni; Sofios, Spyros; Partalidou, Xanthi

2017-06-01

The present work examines the intertemporal causal relationship between environmental damage from carbon emissions released by agriculture per 1000 ha of utilized agriculture area and economic performance in the sector of agriculture as described by net value added per capita. The autoregressive distributed lag bounds testing approach is employed to examine this linkage, for three new entrant EU countries, namely, Bulgaria, Czech Republic, and Hungary. The environmental Kuznets hypothesis is confirmed in the long run for Bulgaria and Czech Republic while in the short run is validated only for the case of Czech Republic. The results indicate that the adoption of environment-friendly farming practices and crops' selection does not secure simultaneous high economic and environmental performance at least in the short run for our sample countries and also in the long run for Hungary necessitating the modification of the agro-environmental measures adopted to make those two targets complementary and not mutually exclusive for a farmer.

Bulgarian military neurosurgery: from Warsaw Pact to the North Atlantic Treaty Organization.

After 45 years as a closest ally of the Soviet Union in the Warsaw Pact, founded mainly against the US and the Western Europe countries, and 15 years of democratic changes, since 2004 Bulgaria has been a full member of NATO and an equal and trusted partner of its former enemies. The unprecedented transformation has affected all aspects of the Bulgarian society. As a function of the Bulgarian Armed Forces, Bulgarian military medicine and in particular Bulgarian military neurosurgery is indivisibly connected with their development. The history of Bulgarian military neurosurgery is the history of the transition from the Union of Soviet Socialist Republics military system and military medicine to NATO standards in every aspect. The career of the military neurosurgeon in Bulgaria is in many ways similar to that of the civilian neurosurgeon, but there are also many peculiarities. The purpose of this study was to outline the background and the history of Bulgarian military neurosurgery as well as its future trends in the conditions of world globalization.

We present a new sedimentological profile and a magnetostratigraphy of the tool-bearing Kozarnika cave sediments from Bulgaria. Modal analysis of cave infilling sedimentary texture indicates that most of the layers are produced by reworked wind-blown sediment (loess). We found evidence for a relatively thick and well defined normal magnetic polarity in the upper-middle part of the section interpreted as a record of the Brunhes Chron, followed downsection by reverse polarity directions. The Brunhes-Matuyama boundary (0.78 Ma) is placed in the upper part of Layer 13 Lower. The lowermost levels with Lower Paleolithic tools are close to - or possibly straddling the - Brunhes-Matuyama boundary. Our results are in substantial agreement with the age of onset of loess deposition in the Danube valley, which occurred shortly before the Brunhes-Matuyama boundary. Moreover, our data fit well with the hypothesis that hominins first entered Europe across a Danube-Po migration conduit during the late Early Pleistocene.

Over the past decade, efforts to value and protect ecosystem services have been promoted by many as the last, best hope for making conservation mainstream. Here, we present the results from the evaluation of the maintenance ecosystem services, provided by the agroecosystems in Bulgaria. The evaluation was conducted on a range of national, European and international databases following the methodology of MAES and classification system of CICES adapted by the Bulgarian Ministry of Environment and Water. During the study, 213857 agroecosystems were evaluated referring to their capacity to maintain pollinators, natural pest control, soil quality and atmospheric carbon sequestration. The capacity of agroecosystems to provide the above mentioned ecosystem services was ranged from moderate to very high, tending the mountainous agroecosystems to be more beneficial than that located in the plains and lowlands. The intensive management of the latter in order to achieve perceived efficiencies in the production of agricultural goods reduces their importance for local and regional ecological processes.

Alternative energy balances for Bulgaria to mitigate climate change

NASA Astrophysics Data System (ADS)

Christov, Christo

1996-01-01

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

Project-based learning in engineering design in Bulgaria: expectations, experiments and results

NASA Astrophysics Data System (ADS)

Raycheva, Regina Pavlova; Angelova, Desislava Ivanova; Vodenova, Pavlina Minkova

2017-11-01

Using a students' workshop as a laboratory, this article summarises the observation of three years' implementation of a new study module for a Bachelor Program in Engineering Design (Interior and Furniture Design) at the University of Forestry, Sofia, Bulgaria. The article offers an analysis of group dynamics and the difficulties and issues observed during the process. Data from survey questionnaires are interpreted; proposals are made for future research. The conclusion of the authors includes the following points: positive response by students, important encounter with successful professionals and companies; creative fulfilment and experience of team work. On the weak side is the experienced discomfort in public presentation, lack of verbal and graphic skills, interpersonal issues and pressure of real requirements from teachers and company; lack of adequate attention by the tutors. The need of better understanding a team 'code' of behaviour and preparation for an active learning method was felt. A proposal leading to a mixed-team organisation for better support of first-time participants in the module is made.

Lunar cycle on an Eneolithic bone artifact from the town of Karnobat, Southeast Bulgaria

NASA Astrophysics Data System (ADS)

Koleva, Vesselina

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.

van de Sanden, M. C. M.; Dimitrova, Miglena; Ghelev, Chavdar

2014-05-01

The International Summer School on Vacuum, Electron and Ion Technologies (VEIT) has been organized biennially since 1977, when the series of VEIT School was launched by the Institute of Electronics, Bulgarian Academy of Sciences with the aim to act as a forum for exchange and dissemination of knowledge and ideas on the latest developments in electron-, ion-, and plasma-assisted technologies. The organizers of the 2013 edition of the event were the Institute of Electronics, Bulgarian Academy of Sciences, Sofia, Bulgaria and the the Dutch Institute for Fundamental Energy Research, Nieuwegein, The Netherlands. While the school has initially been providing a meeting place for researchers mainly from Eastern and Central European countries, its importance has grown issue by issue. The school is now a major scientific event and a meeting place for young scientists from Eastern and Western Europe involved in research and development associated with high-tech industries. Many former school participants have gone on to become leading scientists in research establishments and companies throughout the world. Leading international companies, such as High Voltage Engineering, Balzers, Varian, and Hauzer have used the VEIT forum to present their products through oral presentations, poster contributions or exhibits. The School Proceedings have been published in special issues of the international journals Vacuum, Plasma Processes and Polymers, and Journal of Physics: Conference Series. The eighteenth edition of VEIT was held in the Black Sea resort Sozopol, Bulgaria, on 7-11 October 2013. It was attended by 91 participants from 15 countries: Bulgaria, Czech Republic, France, Germany, Greece, The Netherlands, Portugal, Romania, Russia, Serbia, Slovakia, Slovenia, Sweden, Ukraine and the UK. Following the tradition of publishing the VEIT Proceedings, a selection of papers presented at the event is published in this special issue of Journal of Physics: Conference Series, under the originality and quality criteria of acceptance by the journal, including peer reviewing. The school comprised of fifteen plenary and three poster sessions. At the plenary sessions, 21 invited talks of general interest were presented by highly renowned international experts in the field, as well as 10 progress reports by young scientists. In total, 66 contributed papers were presented during the poster sessions. There were several scientific highlights covering fundamentals of interaction of fast particles with solids and challenging practical applications ranging from novel techniques for creating hard coatings, optical/protective layers, biocompatible materials to nanosized structures produced by evaporation, sputtering or external irradiation. Latest results were presented on ion-beam synthesis and modification in both low-energy (deposition and film growth) and high-energy (sputtering, implantation) regimes, and processing of solid materials aiming at patterning the surface or at creating nanophase systems for electronic or tribological/wear resistant applications. Despite the busy scientific program, the atmosphere was relaxed and informal. The early afternoons of most conference days were free to stimulate both scientific and social interaction between participants, which often took place on the beach. The social program included a welcome party, an official dinner, and an outing to historical landmarks in old Sozopol. VEIT 2013 owes its success to many people. The International Advisory Committee shaped the scientific program and ensured high-quality plenary presentations by careful selection of invited speakers. The Local Committee bore the brunt of the organization both at the conference site and in dealing with correspondence, abstracts, and manuscripts for these proceedings. We are grateful to our sponsors, the Dutch Institute for Fundamental Energy Research, Nieuwegein, The Netherlands, the companies AllData and Astel, and the Ministry of Education and Science of Republic of Bulgaria for their generosity, which enabled us to support the attendance of students and provided support to deal with mailing, printing, renting the conference site, etc. We are also grateful to the members of the International Advisory Committee — Th Czerwiec, M Dimitrova, G Dinescu, A Ehiasarian, N Guerassimov, I Katardjiev, H Kersten, D Mataras, W Möller, I Petrov, Z Petrovic, B Rauschenbach, M C M (Richard) van de Sanden and M Ürgen — for their continuous concern about the high scientific level and the future of the event, as well as for their contribution to the formation of a new generation of scientists and experts in the field. And, last but not least, we would also like to thank all authors for their valuable contributions to these proceedings and to the school, and all reviewers for their hard and tedious, but very important, work. The next conference in the series will be held in September 2015. M C M van de Sanden, Miglena Dimitrova and Chavdar Ghelev Guest Editors Conference photograph

Physical activity and beverage consumption in preschoolers: focus groups with parents and teachers

PubMed Central

2013-01-01

Background Qualitative research is a method in which new ideas and strategies can be discovered. This qualitative study aimed to investigate parents’ and teachers’ opinions on physical activity and beverage consumption of preschool children. Through separate, independent focus groups, they expressed their perceptions on children’s current physical activity and beverage consumption levels, factors that influence and enhance these behaviours, and anticipated barriers to making changes. Methods Multi-cultural and multi-geographical focus groups were carried out in six European countries (Belgium, Bulgaria, Germany, Greece, Poland and Spain). In total, twenty-four focus groups with 122 parents and eighteen focus groups with 87 teachers were conducted between October 2010 and January 2011. Based on a semi-structured interview guide, questions on preschoolers’ physical activity (opinions on preschoolers’ physical activity, how to increase physical activity, facilitators and barriers of physical activity) and beverage consumption (rules and policies, factors influencing promotion of healthy drinking, recommendations for future intervention development) were asked. The information was analyzed using qualitative data analysis software (NVivo8). Results The focus group results indicated misperceptions of caregivers on preschoolers’ physical activity and beverage consumption levels. Caregivers perceived preschoolers as sufficiently active; they argue that children need to learn to sit still in preparation for primary school. At most preschools, children can drink only water. In some preschools sugar-sweetened beverages like chocolate milk or fruit juices, are also allowed. It was mentioned that sugar-sweetened beverages can be healthy due to mineral and vitamin content, although according to parents their daily intake is limited. These opinions resulted in low perceived needs to change behaviours. Conclusions Although previous research shows need of change in obesity-related behaviours, the participants in the current study didn’t perceive such. The awareness of parents and teachers needs to be raised concerning their shared responsibility about healthy behaviours in preschoolers. Providing preschool teachers with ready-to-use classroom material will encourage them to change physical activity and beverage consumption, and to implement related activities in the classroom. Involvement in activities that their children perform at preschool will motivate parents to extend these behaviours to the home environment. PMID:23537117

Qualitative research is a method in which new ideas and strategies can be discovered. This qualitative study aimed to investigate parents' and teachers' opinions on physical activity and beverage consumption of preschool children. Through separate, independent focus groups, they expressed their perceptions on children's current physical activity and beverage consumption levels, factors that influence and enhance these behaviours, and anticipated barriers to making changes. Multi-cultural and multi-geographical focus groups were carried out in six European countries (Belgium, Bulgaria, Germany, Greece, Poland and Spain). In total, twenty-four focus groups with 122 parents and eighteen focus groups with 87 teachers were conducted between October 2010 and January 2011.

Multimedia Educational CD-ROM - The Living Universe

NASA Astrophysics Data System (ADS)

Rosen, Ralev

2002-01-01

I and the other members of the team Celestial Generation dedicate this interactive CD-ROM to our Physics, Astronomy, Biology and English teachers. The members of the team that created the project are Rosen Ralev, Nadezhda Radeva, Iliyan Darganov and Yana Radeva from Technical University of Sofia, the English High schools - Varna, Technical University of Varna and Connecticut College. The leader of the project is Mrs. Veselka Radeva - an astronomer from the Astronomical Observatory in Varna. The main idea of the project " The Living Universe" is that water is a cradle of life in the Universe. As water so abundant in the Universe, life. The project has 4 main themes, combining knowledge from the fields of Biology and Astronomy, one Gallery with our photographs and one amusing theme with interesting and curious facts about life on the Earth and in the Universe. The statistics of our project is: 152 pages and 425 pictures. Over 2/3 from the pictures are ours and we used the rest of them with the kind permission of their authors.The theme Living Water starts with a lyric poem by Petya Dubarova. In the first under-theme- "Water-the cradle of life" introduce you graphics of the structure of the water molecule and its important biological properties. The thesis continues following out the origin and development of life in the oceans on our planet. The next to the last under-theme - sensitive life in water is devoted to dolphins. The third under-theme is " Water in the Universe". Here two of the themes show results from the observations with the space telescope Submillimeter Wave Astronomy Satellite, that found water steams in the interstellar space and around a star in the constellation Leo ( it is supposed that this is a huge comet cloud). This third theme is the most extensive one in this section- it examines the possibility of water being available on each planet in the Solar system: Mercury-most likely there is ice on the polar areas that are the coolest .On Venus it is assumed that there could be living bubble-like creatures in the clouds that are situated 55 km above the surface .A million years ago there was water on Mars. It shows the most recent pictures on which there can be seen the bottom of an ancient ocean. The theme about Mars is enormous and very interesting .The theme continues with the ice cover of Europa . In the places where that ice is broken there could be found life .What follows is the article about the icy satellite of Jupiter-Calisto that has salt oceans under the ice cover .The theme - comets-the space icebergs of the Solar system, leads to the end of the major theme about the water in the Universe. All pictures in this part were made by the group. The next main theme is "The miracle of life". This is the interesting and extensive biological part that includes many themes: it start with the origin of the Universe till the appearance of life on the Earth, the main differences between the living and the non-living; we examine the different definitions of life, the stages of origin of living organisms on our planet. The next main theme is "Habitable worlds". In the first under-theme "The unique planet" there are shown all the conditions in the Solar system that make it unique. Its uniqueness could be the reason why life had developed only in our Solar system. In the next under-theme about the Moon presents the views of the future of the Moon-where there could be situated Moon bases. The next under-theme "Europe-life in the ice breakings". It is most likely that living organisms could exist not only in the oceans under the ice, but also in huge ice breakings. The next information is about Ganymede and Calisto. What is interesting about Titan is that the spot that was seen by scientists most likely has organic composition. Life having been brought by comets is an interesting and disputed theme, but I think that comets spread life in the planet systems. The last theme is bacterial colonizing-it is known that space bacteria can exist in the interstellar. And a script about interstellar bacterial colonizing finishes that theme . Another main theme is SETI. The most interesting things here are the 7 projects for searching for extraterrestrial civilizations. For each project the group found information in 4 areas: by whom it is carried out; what are the goals of the project; what are the technical meanings and how it works. The next under-themes are "Alien forms of life" and "Are we alone?". "The wonderful Universe" is a theme, in which there are included 40 interesting and curious facts about life on the Earth, planets and stars. Here there are 6 images by NASA and the rest 34 were made by me, following the nice text. "The Gallery is my favorite part of the CD-ROM. Here you can find astrophotos made with telescopes in National Astronomical Observatory -Rozhen, space pictures and photo-collages.

Stoyanchev, Todor; Vashin, Ivan; Ring, Christian; Atanassova, Viktoria

2007-10-01

The aim of this study was to investigate the presence of Campylobacter spp. in poultry and poultry products available for the consumers at retail markets in Bulgaria. Samples (n = 210) of poultry carcasses and poultry products for sale at the retail market in Bulgaria were analysed for the presence of Campylobacter spp., of these 35 frozen whole carcasses, 135 chilled poultry cuts (45 wing cuts, 45 thigh cuts and 45 fillet) and 40 thermally treated (ready-to-eat) poultry products. The results obtained showed that 35.2% of the frozen poultry carcasses for sale in the markets were Campylobacter contaminated. In the chilled poultry cuts Campylobacter was isolated at the highest percentage in wing- and thigh cuts, 91.1% and 88.9%, respectively. The fillet samples were contaminated by Campylobacter in 48.9% of cases. In the chilled poultry products as well as in the frozen carcasses C. jejuni (74.8%/70.3%) was the most commonly isolated Campylobacter species, with the remainder being C. coli (25.2%/29.7%). Campylobacter spp. were not detected in the thermally treated poultry products.

Tennantite-tetrahedrite series from the Madan Pb-Zn deposits, Central Rhodopes, Bulgaria

NASA Astrophysics Data System (ADS)

Vassileva, Rossitsa D.; Atanassova, Radostina; Kouzmanov, Kalin

2014-08-01

Minerals from the tennantite-tetrahedrite series (fahlores) are found as single euhedral crystals and crustiform aggregates in hydrothermal veins of the Gradishte and Petrovitsa Pb-Zn deposits of the Madan ore field, southern Bulgaria. Unusually large compositional variations and fine oscillatory crystal zoning were investigated with electron microprobe analysis. The Gradishte samples correspond dominantly to tennantite, while Petrovitsa crystals have exclusively tetrahedrite composition. Fahlore compositions at Madan correspond to zincian varieties (1.6-1.95 apfu), with low Fe-content (<0.45 apfu). Minor silver is characteristic only for the Petrovitsa samples, reaching a maximum of 0.30 apfu. The (Cu+Ag) content of the Petrovitsa tennantites and the Cu content of the Gradishte tetrahedrites systematically exceed 10 apfu resulting in compensation of the excess Cu in the structure by Fe3+. Textural characteristics, mineral relationships and available fluid inclusion and stable isotope data suggest that fahlores precipitated in the late stages of mineralization at Madan, at temperature interval of 300-200 °C from oxidizing fluids with mixed (magmatic-meteoric) signatures.

Lidar measurements of wildfire smoke aerosols in the atmosphere above Sofia, Bulgaria

NASA Astrophysics Data System (ADS)

Peshev, Zahary Y.; Deleva, Atanaska D.; Dreischuh, Tanja N.; Stoyanov, Dimitar V.

2016-01-01

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.

[THE FIRST EPIDEMIOLOGICAL DATA ABOUT THE HR-HUMAN PAPILLOMA VIRUS TYPES IN SOUTH AND NORTHERN BULGARIA].

Kovachev, S; Slavov, V; Slavova, K; Ganovska, A

2015-01-01

The aim of our study were to evaluate the prevalence of HR-HPV infection in women between 15 and 55 years of age in the South and Northern Bulgaria. We have analyzed the HPV status (using DNA-sorb-AM nucleic acid extraction kit) in cervical samples collected during a 3 year period (2010-2012) from 1020 women, aged 15-55 and divided in four age groups, who attended their gynecologists for HPV-DNA cervical test. The rate of the HR-HPV infection was established to be 39.9%. HR-HPV negative were 60.1% of the evaluated subjects. The most commonly isolated genotype in all 407 (100%) infected women was HPV 16 - 190 women (46.7%), followed by HPV 56 - 78 (19.1%), HPV 31- 48 (11.8%) and HPV 33 - 45 (11.1%). To our knowledge, this is the first survey evaluating the prevalence of HR-HPV infection in the South and Northern regions of Bulgarian towns and drawing attention to the unusually high proportion of different HR-HPV.

A new species and new records of Molophilus Curtis, 1833 (Diptera: Limoniidae) from the Western Palaearctic Region.

PubMed

Kolcsár, Levente-Péter; Török, Edina; Keresztes, Lujza

2015-01-01

Molophilus Curtis, 1833 is the most species-rich Limoniidae genus with a total number of 1006 species and subspecies, from which 97 are recorded in the Western-Palaearctic region so far. However new species are still expected from less investigated regions, like the Balkans or the Eastern Europe. In the present article, we desrcibe a new limonid crane fly species, Molophilus balcanicus Kolcsár sp. n. from the Central Balkan area (Bulgaria). This new taxa is closely related to M. serpentiger Edwards, 1938 and M. variispinus Starý​, 1971 based on the external male genital structures, but differs from its siblings mostly in the structure of the inner and outer gonostylus. Additionally, a number of species are reported for the first time from various European countries, like M. variispinus Starý, 1971 and M. occultus de Meijere, 1918 from Romania; M. crassipygus de Meijere 1918, M. obsoletus Lackschewitz, 1940 and M. medius de Meijere, 1918 from Greece; M. flavus Goetghebuer, 1920 from Andorra; M. cinereifrons de Meijere, 1920 from Bulgaria and M. corniger Meijere, 1920 from Spain.

Abstract The genital anatomy of Orcula jetschini (Romania), Orcula zilchi (Bulgaria), and Orcula wagneri (Albania) is described. Based on anatomical features (morphology of the penial caecum) shell characters (sculpture and shape) and unpublished molecular data the genus Orcula is subdivided into three subgenera. Orcula zilchi was classified within the monotypic subgenus Orcula (Hausdorfia) subgen. n.; Orcula jetschini, Orcula wagneri, and Orcula schmidtii were classified to Orcula (Illyriobanatica) subgen. n. (type species: Pupa schmidtii) whereas the other Orcula species remain in the nominotypical subgenus. Orcula (Hausdorfia) is known from South-Eastern Bulgaria and North-Western Turkey, Orcula (Illyriobanatica) inhabits Western Romania, North-Western Greece, Albania, Macedonia, Kosovo, and Montenegro. The nine species of Orcula (Orcula) are known mainly from the Alps and the Western Carpathians (from Eastern France to Eastern Hungary and Slovakia). The occurrence of only one Orcula species namely Orcula jetschini is verified from Romania. Available information suggests that data on the Romanian occurrence of Orcula dolium and Orcula gularis were based on wrongly identified specimens. Sphyradium dobrogicum (=Orcula dobrogica) is considered as a synonym of Sphyradium doliolum. PMID:23794893

In this work the relationship between emergency medical calls for myocardial infarction in Yakutsk (subauroral geomagnetic latitudes) and parameters of the space weather near maximum (1992) and minimum (1998) geomagnetic activity is studied. The comparison of the seasonal behavior of the number of calls with the simultaneous seasonal behavior of deaths from myocardial infarctions at low latitudes (Bulgaria) exhibited significant differences. Namely, in Bulgaria, the maximum and minimum of infarctions were observed in winter and in summer, respectively; in Yakutsk, several observed maximums coincided with the sharp and considerable increase in planetary geomagnetic activity. An analysis of experimental results made it possible to suppose that, in subauroral latitudes, unlike low latitudes, a major role in the increase in the number of infarctions is played by the increase in geomagnetic activity, namely, by the appearance of night magnetospheric substorms, which are also observed in subauroral latitudes in magnetically disturbed times. Substorms are always accompanied by irregular geomagnetic Pi1 pulsations with periods of 0.5-3 Hz. These pulsations can be biotropic, like stable quasi-sinusoidal geomagnetic Pc1 pulsations in middle and low latitudes.

The International Summer School on Vacuum, Electron and Ion Technologies (VEIT) has been organized biennially since 1977, when the VEIT Summer School series was launched by the Institute of Electronics, Bulgarian Academy of Sciences. The aim was to act as a forum for the exchange and dissemination of knowledge and ideas on the latest developments in electron-, ion- and plasma-assisted technologies. The organizers of the 2011 edition of the event were the Institute of Electronics, Bulgarian Academy of Sciences, Sofia, Bulgaria and the Department of Applied Physics, Eindhoven University of Technology, Eindhoven, The Netherlands. Whilst the school initially provided a meeting place for researchers mainly from Eastern and Central European countries, its importance has grown issue by issue. The school is now a major scientific event and a meeting place for young scientists from Eastern and Western Europe involved in research and development associated with high-tech industries. Many former school participants have gone on to become leading scientists in research establishments and companies throughout the world. Leading international companies, such as High Voltage Engineering, Balzers, Varian, and Hauzer have used the VEIT forum to present their products through oral presentations, poster contributions and exhibits. The School Proceedings have been published in special issues of the international journals Vacuum, Plasma Processes and Polymers and Journal of Physics: Conference Series. The Seventeenth edition of VEIT was held in the Black Sea resort of Sunny Beach, Bulgaria on 19-23 September 2011. It was attended by 96 participants from 18 countries: Belgium, Brazil, Bulgaria, Czech Republic, Denmark, France, Germany, Greece, The Netherlands, Romania, Russia, Serbia, Sweden, Switzerland, Turkey, Ukraine, UK and USA. Following the tradition of publishing the VEIT Proceedings, a selection of papers presented at the event is published in this special issue of Journal of Physics: Conference Series, under the originality and quality criteria of acceptance by the journal, including peer reviewing. The school comprised thirteen plenary and three poster sessions. At the plenary sessions, 21 invited talks of general interest were presented by highly-renowned international experts in the field, as well as thirteen progress reports by young scientists. In total, 60 contributed papers were presented during the poster sessions. There were several scientific highlights, covering the fundamentals of interaction of fast particles with solids, and challenging practical applications. These ranged from novel techniques for creating hard coatings, optical/protective layers and biocompatible materials, to nanosized structures produced by evaporation, sputtering or external irradiation. The latest results were presented on ion-beam synthesis and modification in both low-energy (deposition and film growth) and high-energy (sputtering, implantation) regimes, the processing of solid materials aimed at surface patterning, and the creation of nanophase systems for electronic or tribological/wear resistant applications. Despite the busy scientific program, the atmosphere was relaxed and informal. The early afternoons of most conference days were free to stimulate both scientific and social interaction between participants, which often took place on the beach. The social program included a welcome party, an official dinner, and an outing to historical landmarks in the vicinity of Nessebar. VEIT 2011 owes its success to many people. The International Advisory Committee shaped the scientific program and ensured high-quality plenary presentations by their careful selection of the invited speakers. The Local Committee bore the brunt of the organization, both at the conference site and in dealing with correspondence, abstracts, and manuscripts for these proceedings. We are grateful to our sponsor, the Department of Applied Physics, Eindhoven University of Technology, Eindhoven, The Netherlands, for its generosity that enabled us to support the attendance of students, and provided support dealing with mailing, printing, renting the conference site, etc. We are also grateful to the members of the International Advisory Committee: G Dinescu, A Ehiasarian, N Guerassimov, D Mataras, W Möller, I Petrov, Z Petrovic, B Rauschenbach, M C M (Richard) van de Sanden and M Ürgen, for their continuous concern for the high scientific level and the future of the event, and for their contribution to the development of a new generation of scientists and experts in the field. And, last but not least, we would also like to thank all authors for their valuable contributions to these proceedings and to the school, and all reviewers for their hard and tedious, but very important, work. The next conference in the series will be held in September 2013. M C M van de Sanden, Miglena Dimitrova and Chavdar Ghelev Guest Editors

2016-12-01

Burnout syndrome is a phenomenon that seems to be studied globally in relation to all types of populations. The staff in the system of correctional institutions in Bulgaria, however, is oddly left out of this tendency. There is no standardized model in Bulgaria that can be used to detect possible susceptibility to professional burnout. The methods available at present only register the irreversible changes that have already set in the functioning of the individual. V. Boyko's method for burnout assessment allows clinicians to use individual approach to patients and affords easy comparability of results with data from other psychodiagnostic instruments. Adaptation of the assessment instruments to fit the specificities of a study population (linguistic, ethno-cultural, etc.) is obligatory so that the instrument could be correctly used and yield valid results. Validation is one of the most frequently used technique to achieve this. The aim of the present study was to adapt and validate V. Boyko's burnout inventory for diagnosing burnout and assessment of the severity of the burnout syndrome in correctional officers. We conducted a pilot study with 50 officers working in the Plovdiv Regional Correction Facility by test-retest survey performed at an interval of 2 to 4 months. All participants completed the adapted questionnaire translated into Bulgarian voluntarily and anonymously. Statistical analysis was performed using SPSS v.17. We found a mild-to-strong statistically significant correlation (P<0.01) across all subscales between the most frequently used questionnaire for assessing the burnout syndrome, the Maslach Burnout Inventory, and the tool we propose here. The high Cronbach's α coefficient (α=0.94) and Spearman-Brown coefficient (rsb=0.86), and the low mean between-item correlation (r=0.30) demonstrated the instrument's good reliability and validity. With the validation herein presented we offer a highly reliable Bulgarian variant of Boyko's method for burnout assessment and research.

Medications and their prices are key issues for healthcare. Although access to medicines at affordable prices had been specified as a key objective of the European Health Policy, it seems that these goals have not been achieved. Therefore, we attempted an evaluation of affordability of selected medicines at full prices. The analysis concerned 2012 and was conducted between 2013 and 2015 in all the European Union (EU) countries divided into 3 groups depending on the date of their accession to the EU. Finally, we considered 9 originators used in the treatment of schizophrenia and multiple sclerosis. Information on drug prices were collected from pharmacies. Participation in the study was voluntary and anonymous in order to avoid accusations of advertising. To evaluate affordability, several factors were used (e.g. minimum earnings and Gini coefficient). Due to unavailability in some countries, the exact number of analyzed medicines varies. Drug prices vary significantly between EU Member States. Almost eleven fold difference was observed between Germany (EUR 1451.17) and Croatia (EUR 132.77) in relation to Interferone beta-1a 22 μg. Generally, prices were the highest in Germany. The cheapest drugs were found in various countries but never in the poorest ones like Bulgaria or Romania. Discrepancies in wages were observed too (the smallest minimum wage was EUR 138.00 in Bulgaria and the highest EUR 1801.00 in Luxembourg). Full price of olanzapine 5mg, however, was higher in Bulgaria (EUR 64.53) than, for instance, in Belgium (EUR 37.26). Analyzed medications are still unaffordable for many citizens of the EU. Besides, access to medicines is also impaired e.g. due to parallel trade. Unaffordability of medications may lead to the patients' non-compliance and therefore to increased direct and indirect costs of treatment. Common European solutions are needed to achieve a real affordability and accessibility of medications.

Budget impact of rare diseases: proposal for a theoretical framework based on evidence from Bulgaria.

2015-05-01

This study aimed to estimate the impact of rare disease (RD) drugs on Bulgaria's National Health Insurance Fund's (NHIF) total drug budget for 2011-2014. While standard budget impact analysis is usually used in a prospective way, assessing the impact of new health technologies on the health system's sustainability, we adopted a retrospective approach instead. Budget impact was quantified from a NHIF perspective. Descriptive statistics was used to analyse cost details, while dynamics was studied, using chain-linked growth rates (every period preceding the accounting period serves as a base). NHIF costs for RD therapies were expected to increase up to 74.5 million BGN in 2014 (7.8% of NHIF's total pharmaceutical expenditure). Greatest increase in cost per patient and number of patients treated was observed in conditions, for which there were newly approved for funding therapies. While simple cost drivers are well known - number of patients treated and mean cost per patient - in real-world settings these two factors are likely to depend on the availability and accessibility of effective innovative therapies. As RD were historically underdiagnosed, undertreated and underfunded in Bulgaria, improved access to RD drugs will inevitably lead to increasing budget burden for payers. Based on the evidence from this study, we propose a theoretical framework of a budget impact study for RD. First, a retrospective analysis could provide essential health policy insights in terms of impact on accessibility and population health, which are significant benchmarks in shaping funding decisions in healthcare. We suggest an interaction between the classical prospective BIA with the retrospective analysis in order to optimise health policy decision-making. Second, we recommend budget impact studies to focus on RD rather than orphan drugs (OD). In policy context, RD are the public health priority. OD are just one of the tools to address the complex issues of RD. Moreover, OD is a dynamic characteristic and compromises the consistency and comparability of the calculated budget indicators.

Heart disease attributed to occupational noise, vibration and other co-exposure: Self-reported population-based survey among Bulgarian workers.

PubMed

Dzhambov, Angel M; Dimitrova, Donka D

Cardiovascular disease (CVD) is the main mortality cause worldwide. Noise and vibration are considered to be occupational risk factors, but little is known about their cardiovascular effects in Bulgaria in terms of gender and various professional groups. The aim of this study has been to investigate the risk of prevalent CVD, associated with occupational noise and vibration exposure. We conducted a secondary analysis of the data from 3 waves of the European Working Conditions Survey (EWCS) 2001-2010 - a nationally-representative cross-sectional questionnaire survey covering 3149 workers aged ≥ 15 years in Bulgaria. Data on self-reported heart disease were linked to self-reported occupational noise and vibration, adjusting for other factors. Results from the 3 waves were pooled together using the inverse variance heterogeneity (IVhet) meta-analysis. For noise, the risk was elevated among women (relative risk (RR) = 1.26, 95% confidence interval (CI): 0.53-3.01), but not men (RR = 0.49, 95% CI: 0.14-1.65). Long-term workers had RR = 1.01, 95% CI: 0.60-1.69. For vibration, the risk was increased in all participants. It was higher among men (RR = 2.56, 95% CI: 1.60-4.09) than it was among women (RR = 1.32, 95% CI: 0.77-2.27). Among long-term, industrial, and service workers it was RR = 1.56, 95% CI: 1.02-2.40; RR = 1.10, 95% CI: 0.61-1.98, and RR = 1.18, 95% CI: 0.57-2.46, respectively. Occupational vibration was a risk factor for prevalent heart disease in Bulgaria. Noise was an alleged risk factor only among long-term workers and women. Med Pr 2016;67(4):435-445.

A severe radiation accident occurred on 14 June 2011 in an industrial irradiation facility for medical equipment sterilization in Bulgaria. Five people were exposed for 5-10 min to a 60Co source containing 137 TBq. The Emergency Department of the National Centre of Radiobiology and Radiation Protection (NCRRP), Bulgaria, put into practice the plans for providing medical care in radiation accidents and the procedures developed for assessment of injury severity, the decision-making algorithm regarding subsequent treatment, and the therapy for persons affected. The activities performed for initial assessment of the severity of injury of irradiated patients were published in 2012. Based on predictive assessments of the severity of radiation damage, it was decided that the victims required hospitalization at a specialized hematology clinic. Percy Hospital in Paris was chosen for this purpose. The aim of this report is to present the results of 1-y follow-up for three of the victims. Sadly, 1 mo after the accident, Patient 4 died from a heart attack. The medical opinion was that this was not a direct outcome of the irradiation. Patient 5 was only followed up for 4 mo (118 d) because medical follow-up is voluntary, and despite repeated calls, the patient did not respond. Medical examinations by a physician as well as hematology and biochemical tests were performed using standard laboratory methods. The obtained results were compared to the victims' personal reference limits obtained from annual health monitoring. After the accident, the recovery to normal content of peripheral blood cells was observed in all victims. Nevertheless, there were observed cases of thrombocytopenia, granulocytopenia, and leucocytopenia at various times after exposure. During the period of observation, morphological changes in red blood cells such as anisomicrocitosis, macrocytes, megalocytes, and polychromatic erythrocytes were demonstrated. During the 1-y observation period, all victims showed immediate hematopoietic recovery within 2 mo after irradiation. Slight hypocellularity of bone marrow was noted at the end of the year.

The territory of Bulgaria represents a typical example of high seismic risk area in the eastern part of the Balkan Peninsula. The neotectonic movements on the Balkan Peninsula were controlled by extensional collapse of the Late Alpin orogen, and were influenced by extension behind the Aegean arc and by the complicated vertical and horizontal movements in the Pannonian region. The city of Sofia is the capital of Bulgaria. It is situated in the centre of the Sofia seismic zone that is the most populated (more than 1.2 mil. inhabitants), industrial and cultural region of Bulgaria that faces considerable earthquake risk. Seismicity in the zone is related mainly to the marginal neotectonic faults of Sofia graben. The available historical documents prove the occurrence of destructive earthquakes during the 15th-18th centuries in the Sofia zone. In 19th century the city of Sofia has experienced two strong earthquakes: the 1818 earthquake with epicentral intensity I0=8-9 MSK and the 1858 earthquake with I0=IX-X MSK64. The 1858 earthquake caused heavy destruction in the town of Sofia and the appearance of thermal springs in the western part of the town. After a quiescence of about 50 years a strong event with M=6.5 occurred in 1905 near the western marginal part of the Sofia zone. During the 20th century the strongest event occurred in the vicinity of the city of Sofia is the 1917 earthquake with MS=5.3 (I0=7-8 MSK64). The earthquake caused a lot of damages in the town and changed the capacity of the thermal mineral springs in Sofia and the surrounding villages. The earthquake was felt in an area of 50000 km2 and followed by aftershocks, which lasted more than one year. Almost a century later (95 years) an earthquake of moment magnitude 5.6 hit Sofia seismic zone, on May 22nd, 2012, at 25 km south west of the city of Sofia. This shallow earthquake was largely felt in the region and up to Greece, FYROM, Serbia and Romania. No severe injuries have been reported so far, though a state of emergency was declared in Pernik (the closest city to the epicenter) and superficial damages were observed. The present study was aimed at both presenting the results of seismological study carried out (such as analysis of wave forms, fault plane solutions, spatial distribution of intensity field, temporal aftershocks distribution) and at weighting in the balance to stress outstanding problems. The earthquake hit Bulgaria on May 22, 2012 gave lots of precious lessons to learn, especially in anticipating other disaster that may occur un-predictably in the future.

We present recent optical photometric observations of the blazar OJ 287 taken during 2015 September-2016 May. Our intense observations of the blazar started in 2015 November and continued until 2016 May and included detection of the large optical outburst in 2015 December that was predicted using the binary black hole model for OJ 287. For our observing campaign, we used a total of nine ground-based optical telescopes of which one is in Japan, one is in India, three are in Bulgaria, one is in Serbia, one is in Georgia, and two are in the USA. These observations were carried out in 102 nights with a total of ∼1000 image frames in BVRI bands, though the majority were in the R band. We detected a second comparably strong flare in 2016 March. In addition, we investigated multiband flux variations, colour variations, and spectral changes in the blazar on diverse time-scales as they are useful in understanding the emission mechanisms. We briefly discuss the possible physical mechanisms most likely responsible for the observed flux, colour, and spectral variability.

Given the ubiquitous nature of both noise pollution and mental disorders, their alleged association has not escaped the spotlight of public health research. The effect of traffic noise on mental health is probably mediated by other factors, which have not been elucidated sufficiently. Herein, we aimed to disentangle the pathways linking road traffic noise to general mental health in Bulgarian youth, with a focus on several candidate mediators - noise annoyance, perceived restorative quality of the living environment, physical activity, and neighborhood social cohesion. A cross-sectional sample was collected in October - December 2016 in the city of Plovdiv, Bulgaria. It consisted of 399 students aged 15-25years, recruited from two high schools and three universities. Road traffic noise exposure (L den ) was derived from the strategic noise map of Plovdiv. Mental health was measured with the 12-item form of the General Health Questionnaire (GHQ-12). Noise annoyance, perceived restorative quality of the living environment, commuting and leisure time physical activity, and neighborhood social cohesion were assessed using validated questionnaires. Analyses were based on linear regression mediation models and a structural equation modeling (SEM) to account for the hypothesized interdependencies between candidate mediators. Results showed that higher noise exposure was associated with worse mental health only indirectly. More specifically, tests of the single and parallel mediation models indicated independent indirect paths through noise annoyance, social cohesion, and physical activity. In addition, the SEM revealed that more noise annoyance was associated with less social cohesion, and in turn with worse mental health; noise annoyance was also associated with lower neighborhood restorative quality, thereby with less social cohesion and physical activity, and in turn with worse mental health. However, causality could not be established. Further research is warranted to expand our still limited understanding of these person-environment interactions. Copyright © 2017 Elsevier Ltd.

The total ozone and UV solar radiation over Stara Zagora, Bulgaria

NASA Astrophysics Data System (ADS)

Mendeva, B. D.; Gogosheva, Ts. N.; Petkov, B. H.; Krastev, D. G.

The results from direct ground-based solar UV irradiance measurements and the total ozone content (TOC) over Stara Zagora (42° 25'N, 25° 37'E), Bulgaria are presented. During the period 1999-2003 the TOC data show seasonal variations, typical for the middle latitudes - maximum in the spring and minimum in the autumn. The comparison between TOC ground-based data and Global Ozone Monitoring Experiment (GOME) satellite-borne ones shows a seasonal dependence of the differences between them. A strong negative relationship between the total ozone and the 305 nm wavelength irradiance was found. The dependence between the two variables is significant ( r = -0.62 ± 0.18) at 98% confidence level. The direct sun UV doses for some specific biological effects (erythema and eyes) are obtained. The estimation of the radiation amplification factor RAF shows that the ozone reduction by 1% increases the erythemal dose by 2.3%. The eye-damaging doses are more influenced by the TOC changes and in this case RAF = -2.7%. The amount of these biological doses depended on the solar altitude over the horizon. This dependence was not so strong when the total ozone content in the atmosphere was lower.

Landscape change analysis and assessment (case studies in Slovakia and Bulgaria)

2009-03-01

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.

Smokers’ compliance with smoke-free policies, and non-smokers’ assertiveness for smoke-free air in the workplace: a study from the Balkans.

PubMed

Lazuras, Lambros; Zlatev, Martin; Rodafinos, Angelos; Eiser, J Richard

2012-10-01

Identify the psychosocial variables that predict smokers’ compliance with smoke-free policies at work, and non-smokers’ assertiveness for smoke-free rights in Greek and Bulgarian workplaces. Data were collected from employees in Greece and Bulgaria. The main outcome measures were smokers’ compliance with smoke-free policies, and non-smokers’ assertiveness intentions. Demographic variables, tobacco use and dependence, as well as beliefs about second-hand smoke (SHS) exposure and smoking at work were also assessed. Regression analyses showed that smokers’ compliance with smoke-free policies was predicted by age, perceived health risks of smoking, and beliefs related to the benefits of smoking at work. Non-smokers’ assertiveness was predicted by annoyance from exposure to SHS at work, and assertiveness-related social cognitions (e.g., attitudes, social norms, and self-efficacy). Interventions to promote support for tobacco control policies at work in Greece and Bulgaria may benefit from targeting smokers’ beliefs about the actual effects of tobacco use on health and job performance. Accordingly, efforts to promote non-smokers assertiveness should build stronger assertiveness-related attitudes, convey anti-smoking normative messages, and strengthen self-efficacy skills.

Association between Noise Pollution and Prevalent Ischemic Heart Disease.

PubMed

Dzhambov, Angel M; Dimitrova, Donka D

2016-12-01

Noise pollution is considered a risk factor for ischemic heart disease (IHD). Both are highly prevalent in Bulgaria, but their association has not been studied sufficiently. The aim of the present study was to examine the risk of IHD associated with road traffic (Lden) and lifetime occupational noise exposure (LONE) in a Bulgarian sample. A cross-sectional survey was carried out among 513 residents of Plovdiv, Bulgaria. A questionnaire asked about doctor-diagnosed IHD, LONE and confounding factors. Lden was derived from official noise map after geocoding participants' addresses. In log-link Poisson regressions we investigated the relative risks of prevalent IHD. Sensitivity analyses examined subgroup differences. Lden ≥ 65 dB was associated with higher risk (RR=1.84, 95% CI: 0.61, 5.57) of IHD in long-term residents (≥ 20 years). LONE was associated with RR=1.76 (0.82, 3.78) for ever-exposed; and RR=2.35 (1.00, 5.52) for 15 - 47 years exposure. Exposure to Lden≥65 dB was associated with non-significantly higher risk of IHD. Longer LONE was consistently associated with higher risk. In some subgroups the effect of noise was more pronounced.

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.

A new species and new records of Molophilus Curtis, 1833 (Diptera: Limoniidae) from the Western Palaearctic Region

2015-01-01

Abstract Background Molophilus Curtis, 1833 is the most species-rich Limoniidae genus with a total number of 1006 species and subspecies, from which 97 are recorded in the Western-Palaearctic region so far. However new species are still expected from less investigated regions, like the Balkans or the Eastern Europe. New information In the present article, we desrcibe a new limonid crane fly species, Molophilus balcanicus Kolcsár sp. n. from the Central Balkan area (Bulgaria). This new taxa is closely related to M. serpentiger Edwards, 1938 and M. variispinus Starý​, 1971 based on the external male genital structures, but differs from its siblings mostly in the structure of the inner and outer gonostylus. Additionally, a number of species are reported for the first time from various European countries, like M. variispinus Starý, 1971 and M. occultus de Meijere, 1918 from Romania; M. crassipygus de Meijere 1918, M. obsoletus Lackschewitz, 1940 and M. medius de Meijere, 1918 from Greece; M. flavus Goetghebuer, 1920 from Andorra; M. cinereifrons de Meijere, 1920 from Bulgaria and M. corniger Meijere, 1920 from Spain.

Mycotoxic nephropathy in Bulgarian pigs and chickens: complex aetiology and similarity to Balkan endemic nephropathy.

PubMed

Stoev, S D; Dutton, M F; Njobeh, P B; Mosonik, J S; Steenkamp, P A

2010-01-01

Spontaneous nephropathy in Bulgaria, which is observed frequently during meat inspection and which differs morphologically from the classical description of mycotoxic porcine/chicken nephropathy as made in Denmark, was found to have a multi-mycotoxic aetiology being mainly provoked by a combined effect of ochratoxin A, penicillic acid and fumonisin B1 in addition to a not-yet-known metabolite. Mean contamination levels of ochratoxin A were consecutively low (188.8 and 376.4 microg kg(-1)) in contrast to high contamination levels of fumonisin B1 (5564.1 and 3254.5 microg kg(-1)) and penicillic acid (838.6 and 904.9 microg kg(-1)) for 2006 and 2007, respectively. Some other mycotoxins with lower importance such as citrinin, penitrem A, etc., may also influence clinicopathological picture of this nephropathy. A heavy contamination with Gibberella fujikuroi var. moniliformis (Fusarium verticillioides) and Penicillium aurantiogriseum complex (mainly Penicillium polonicum) was observed in almost all examined feed samples coming from pig and chick farms with nephropathy problems from Bulgaria. In contrast, low contamination with Aspergillus ochraceus, Penicillium verrucosum and Penicillium citrinum was observed in the same feed samples and these species were isolated as very rare components of the mycobiota.

Stoeva, Penka; Stoev, Alexey

In recent years, more and more attention is paid to educational programmes, which are closely connected with the process of scientific research. Such programmes are developed in collab-oration and included in the schools, universities and scientific institutes in Bulgaria. They are also used in the organization of public events aimed to demonstrate beauty, relevance and significance of Space and Earth science to the whole world. During the last four years, So-lar-Terrestrial Influences Institute of the Bulgarian Academy of Sciences, and the Yuri Gagarin Public Astronomical Observatory and Planetarium, Stara Zagora succeeded to build an ex-cellent partnership, working on the International Heliophysical year and International Year of Astronomy -global efforts initiated by the UNESCO and the International Astronomical Union (IAU) to help the citizens of the world rediscover their place in the Universe. They organized and tutored all the Astronomical Observatories and Planetaria, and teachers from all around Bulgaria to participate in the world initiatives Solar Week, Sun-Earth Day,Yuri's Night, World Astronomy day and World Space week, and use them in the process of education and public outreach. After the official closing of the International Heliophysical year, the IHY follow-on activities in Bulgaria continued and were devoted to the International Year of Astronomy 2009. A lot of lectures, public talks and exhibitions have been organized. Stara Zagora became a host of IHY Space Weather Monitor -SID (Sudden Ionospheric Disturbances), numerous of educational materials have been adapted and translated in Bulgarian. Cycle of lectures "Epock of Great astronomical discoveries", devoted to the International Year of Astronomy was given in April 2009 in the Stara Zagora Art Gallery. Participation in the cornerstone projects of the International Year of Astronomy 2009 was organized: "100 hours of Astronomy" -ob-servations with small telescopes in the period of 5 -9 April 2009 -more than 5000 people were happy to observe the Sun, Moon, Venus and other celestial objects; "The Galileoscope"; "Galilean Nights" -encourages everybody to go out to the streets and observe the cosmos; "Dark Skies Awareness" -Measuring of the light pollution level above the region of Stara Zagora; "Astronomy and World Heritage" -archaeoastronomical research of megalithic mon-uments and sanctuaries -examples of ancient observatories for observations of solar extreme rises, sets and meridional culminations; history of the first modern astronomical observatory in Bulgaria; "Galileo Teacher Training Program" -Teaching the teachers. At the beginning of every school year teacher-training course is conducted on astronomy and astrophysics. This year they will actively use telescopes to observe the sky with students; "Universe Awareness" -a lot of games and observations, modeling, exhibitions and parties are organized. "From Earth to the Universe" Exhibitions of astronomical photographs from space and ground based telescopes. Astronomy Olympiads -scientific teaching is improved when the students engaged in doing real science on real data. Fifteen years we participate in the International Astronomy Olympiad and our students win medals. Observarion of solar eclipses is an example of educa-tion in science research environment. We were happy to observe the longest for the last 2000 years total solar eclipse on July 22, 2009, in TianHuangPing, China, at 900m above the sea level. Immediately after the end of this unique phenomenon, images of the eclipsed Sun were sent in Bulgaria. Cooperations -we have good international and national cooperations with a lot of Institutes, Universities, organizations and mass media -radio, TV, magazines, news-papers Information and press conferences about the events have been regularly made available for journalists. With the experience we gained from the IHY and IYA initiatives, being a host of a SID Monitor, we focus on the new International Space Weather Initiative (ISWI) aimed to continue the study of universal processes in the solar system and to contribute to understanding the impacts of Space Weather on Earth and the near-Earth environment.

Type-2 diabetes (T2D) is one of the fastest growing chronic diseases worldwide. The PREVIEW project has been initiated to find the most effective lifestyle (diet and physical activity) for the prevention of T2D, in overweight and obese participants with increased risk for T2D. The study is a three-year multi-centre, 2 × 2 factorial, randomised controlled trial. The impact of a high-protein, low-glycaemic index (GI) vs. moderate protein, moderate-GI diet in combination with moderate or high-intensity physical activity on the incidence of T2D and the related clinical end-points are investigated. The intervention started with a two-month weight reduction using a low-calorie diet, followed by a randomised 34-month weight maintenance phase comprising four treatment arms. Eight intervention centres are participating (Denmark, Finland, United Kingdom, The Netherlands, Spain, Bulgaria, Australia, and New Zealand). Data from blood specimens, urine, faeces, questionnaires, diaries, body composition assessments, and accelerometers are collected at months 0, 2, 6, 12, 18, 24, and 36. In total, 2326 adults were recruited. The mean age was 51.6 (SD 11.6) years, 67% were women. PREVIEW is, to date, the largest multinational trial to address the prevention of T2D in pre-diabetic adults through diet and exercise intervention. Participants will complete the final intervention in March, 2018. PMID:28632180

Understanding the complexity of live pig trade organization is a key factor to predict and control major infectious diseases, such as classical swine fever (CSF) or African swine fever (ASF). Whereas the organization of pig trade has been described in several European countries with indoor commercial production systems, little information is available on this organization in other systems, such as outdoor or small-scale systems. The objective of this study was to describe and compare the spatial and functional organization of live pig trade in different European countries and different production systems. Data on premise characteristics and pig movements between premises were collected during 2011 from Bulgaria, France, Italy, and Spain, which swine industry is representative of most of the production systems in Europe (i.e., commercial vs. small-scale and outdoor vs. indoor). Trade communities were identified in each country using the Walktrap algorithm. Several descriptive and network metrics were generated at country and community levels. Pig trade organization showed heterogeneous spatial and functional organization. Trade communities mostly composed of indoor commercial premises were identified in western France, northern Italy, northern Spain, and north-western Bulgaria. They covered large distances, overlapped in space, demonstrated both scale-free and small-world properties, with a role of trade operators and multipliers as key premises. Trade communities involving outdoor commercial premises were identified in western Spain, south-western and central France. They were more spatially clustered, demonstrated scale-free properties, with multipliers as key premises. Small-scale communities involved the majority of premises in Bulgaria and in central and Southern Italy. They were spatially clustered and had scale-free properties, with key premises usually being commercial production premises. These results indicate that a disease might spread very differently according to the production system and that key premises could be targeted to more cost-effectively control diseases. This study provides useful epidemiological information and parameters that could be used to design risk-based surveillance strategies or to more accurately model the risk of introduction or spread of devastating swine diseases, such as ASF, CSF, or foot-and-mouth disease.

Household energy management strategies in Bulgaria's transitioning energy sector

NASA Astrophysics Data System (ADS)

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 socioeconomic development. Thus far, the state has taken a very limited role in improving residential energy efficiency despite the increased energy expenditure burdens that most households face. Yet lacking are affordable technologies, educational campaigns, and individual financing mechanisms or incentives. As shown, where there is an informed, active, and financially capable population, improved household efficiency is more likely to be the winning strategy for both the goals of the individual as well as of the state.

Snake venom poisoning in the Plovdiv region from 2004 to 2012.

Envenomation by poisons of biological origin is very common globally in the tropical and subtropical areas mainly, where the biological diversity of the species clearly leads to evolution of highly toxic species. The weather warming trend in Bulgaria, whether cyclic or permanent, allows for a change in the biological response of reptiles and insects inhabiting the temperate zone by a possible migration of biological species from the subtropical zone towards the temperate zone because of the new environmental conditions. There are very few studies on snake bite envenoming in Bulgaria. The AIM of the study was to find the incidence of the acute accidental intoxication (AAI) caused by snake venom in adult individuals in a large region of Bulgaria between 2004 and 2012 and characterises it by number, type, main clinical features, course and socio-demographic parameters of the victims so that preventive measures can be taken, wherever necessary. We studied retrospectively all 68 cases of AAI caused by snake venom in adult individuals (> 18 years old) hospitalized in the Clinic of Toxicology in St. George University Hospital, Plovdiv over the period from 2004 to 2012 by 23 quantitative and qualitative parameters. We found that the average annual incidence of snake venom AAI in adult population in the region of Plovdiv was relatively low for the specified period (9.5 per 100000 residents); the snake venom AAI increases or decreases every other year, with no clearly delineated trend for now. The prevalence of envenomation by poisons of biological origin increased from 2.3% in 1990-1998 to 9.5-10.33% between 2007 and 2012. The main sociodemographic characteristics of snake bite victims are similar to those in other Balkan and Central European countries. The clinical response to poisons of biological origin is generally identical with the response to the viper (Vipera ammodytes)--mild to medium intensity with predominantly local toxic syndrome. The algorithm of Clinical Pathway 293 (CP) is effective and conducive to the reduction of duration of the morbid condition. There are, however, still aspects of it that can be optimised.

Phylogeography of the Golden Jackal (Canis aureus) in India

The golden jackal (Canis aureus) is one of the most common and widely distributed carnivores in India but phylogeographic studies on the species have been limited across its range. Recent studies have observed absence of mitochondrial (mt) DNA diversity in European populations while some North African populations of golden jackal were found to carry gray wolf (Canis lupus lupaster) mtDNA lineages. In the present study, we sequenced 440 basepairs (bp) of control region (CR) and 412 bp of cytochrome b (cyt b) gene of mtDNA from 62 golden jackals sampled from India (n = 55), Israel (n = 2) and Bulgaria (n = 5), to obtain a total of eighteen haplotypes, comprising sixteen from India and one each from Israel and Bulgaria. Except for three previously described haplotypes represented by one cyt b and one CR haplotype both from India, and one CR haplotype from Bulgaria, all haplotypes identified in this study are new. Genetic diversity was high in golden jackals compared to that reported for other canids in India. Unlike the paraphyletic status of African conspecifics with the gray wolf, the Indian (and other Eurasian) golden jackal clustered in a distinct but shallow monophyletic clade, displaying no evidence of admixture with sympatric and related gray wolf and domestic dog clades in the region. Phylogeographic analyses indicated no clear pattern of genetic structuring of the golden jackal haplotypes and the median joining network revealed a star-shaped polytomy indicative of recent expansion of the species from India. Indian haplotypes were observed to be interior and thus ancestral compared to haplotypes from Europe and Israel, which were peripheral and hence more derived. Molecular tests for demographic expansion confirmed a recent event of expansion of golden jackals in the Indian subcontinent, which can be traced back ~ 37,000 years ago during the late Pleistocene. Our results suggest that golden jackals have had a potentially longer evolutionary history in India than in other parts of the world, although further sampling from Africa, the Middle East and south-east Asia is needed to test this hypothesis.

IN MY OPINION: Taking part matters

For a week last July, the University of Leicester played host to the 31st International Physics Olympiad. Sixty-three countries sent teams of five students, accompanied by two Leaders who were professors or teachers. The students faced two five-hour exams, one theory and one practical, woven into a week of visits and fun. The International Physics Olympiad has been held since 1967. The idea originated at a conference of the Czechoslovak Physical Society in Prague and the first competition was in Warsaw with teams from Bulgaria, Czechoslovakia, Hungary, Poland and Romania participating. The competition has grown in size and scope over the decades, and in 1991 it was awarded the medal of the International Commission on Physics Education. The citation reads `the International Physics Olympiad has become an achievement of world wide impact, and physics educators from various countries around the world have attested to the strong influence it has had in stimulating interests in physics among both students and teachers in their countries'. The British Physics Olympiad team was chosen from Year 13 students who had come through the selection procedure. Schools are invited to challenge their best pupils with a preliminary paper, sat and marked at school. Students gaining above a given threshold are encouraged to sit a second, three-hour paper, which is centrally marked and graded. From among the Gold-medal winners in this exam, the team of five is selected. Amid the pressures of A-levels, some practical and theory tuition is fitted in before the competition. The different countries use a variety of selection methods and coaching. The Australians managed a week of scientific and cultural education in Vienna prior to arriving at Leicester, and several teams talked of pre-competition work-camps. How much Physics can be crammed into a week? Countries that have institutions selecting pupils highly gifted in Maths and Science have a great start, as do those with the most demanding syllabuses for pre-university exams. In years gone by, some of our most gifted students happened to be taught by some of our most able teachers, and together they tackled the old Scholarship-level papers. The old O-level work gave students a solid grounding in classical mechanics, electricity and magnetism, with lots of sums on which to anchor the concepts. Those who enjoyed this aspect of the science could launch into A-level studies of Maths, Physics, Chemistry and/or Further Maths, and relish the challenges hidden in the syllabuses. Advanced level aims have changed. Mathematical elements have been played down; traditional proofs and applications may be referred to but are no longer required learning for the candidates. The modular system allows less repetitive revision and consolidation of ideas so that students are not required to immerse themselves in the subject in the same way as a generation ago. Does this matter? The `new way' hopes to attract some students into Physics and Engineering who would have been intimidated by the rigour and commitment required to do well in the old system. The single-minded student has a wealth of information available to further his or her studies and will not be limited by the dictates of any syllabus. However, without the need to meet exam requirements, many of our most able students have been deprived of the pleasure of advancing their knowledge so far at school, and must wait for a degree course to take up the story. (We should worry if many of these potential scientists get deflected from Physics.) The change in A-level targets inevitably means that the UK is slipping down the IPhO medal table, but in the Olympic tradition it is the taking part that matters. The 31st Olympiad was won by the People's Republic of China, with five gold medals out of five. Heartiest congratulations to them and to Russia, who came second with two gold, two silver and a bronze. The other gold medals went to Hungary (2), India (2), Taiwan (2), Bulgaria (1) and Switzerland (1). The UK team won two bronze medals. Who will be lucky enough to go to IPhO 2001, to be held in Turkey next summer, and will the teams include more than 13 girls? All the very able young people gathered in Leicester had a wealth of experiences beyond Physics. Friendships made may last a lifetime and, funding permitting, the UK may be lucky enough to welcome some of them back as students or graduate students. For further information on IPhO see: www.star.le.ac.uk/IPhO-2000 or contact Dr C Isenberg at Physics Laboratory, University of Kent at Canterbury, Canterbury CT2 7NR (e-mail C.Isenberg@ukc.ac.uk).

Microgravity Effects on Water Supply and Substrate Properties in Porous Matrix Root Support Systems

The control of water content and water movement in granular substrate-based plant root systems in microgravity is a complex problem. Improper water and oxygen delivery to plant roots has delayed studies of the effects of microgravity on plant development and the use of plants in physical and mental life support systems. Our international effort (USA, Russia and Bulgaria) has upgraded the plant growth facilities on the Mir Orbital Station (OS) and used them to study the full life cycle of plants. The Bulgarian-Russian-developed Svet Space Greenhouse (SG) system was upgraded on the Mir OS in 1996. The US developed Gas Exchange Measurement System (GEMS) greatly extends the range of environmental parameters monitored. The Svet-GEMS complex was used to grow a fully developed wheat crop during 1996. The growth rate and development of these plants compared well with earth grown plants indicating that the root zone water and oxygen stresses that have limited plant development in previous long-duration experiments have been overcome. However, management of the root environment during this experiment involved several significant changes in control settings as the relationship between the water delivery system, water status sensors, and the substrate changed during the growth cycles.

Within the scope of the present study a field survey in the area of "Strandzha" Natural Park in south-east Bulgaria was carried out. The main goal of the investigation was to gain more detailed information on the diet of the European otters (Lutra lutra) that inhabit the park. As indicators for the presence of the mustelids a set of standard procedures, such as footprints tracking and inspecting the terrain for otter spraints were used. A total of 204 excrements were found, measured, documented and then disintegrated in water. The food rests in the faeces were investigated and the diet of the local population was documented. On the base of the results we separated the excrements into six groups and analysed the relations between the contents of the spraints and the characteristics of the habitat where they were found. We discovered a clear tendency toward piscivory in the middle and down streams of the studied rivers in the Natural Park. In the upper streams, otters relied almost exclusively on invertebrates like bivalves and crayfish as food source. The fact, that even suboptimal habitats, which offered invariable menu, were exploited by the otters is an indication for the stability of the local population.

Assessment of Heavy Metal Accumulation in the Golden Jackal (Canis aureus) as a Possible Bioindicator in an Agricultural Environment in Bulgaria.

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

The Role of Eating Habits on the Iron Status of Pregnant Women.

This study highlights the relationship between some eating habits and iron status during pregnancy. The study included 219 healthy pregnant women aged 27.6 ± 5.7 years from southern Bulgaria. Subjects' iron status was assessed on the basis of the following iron indicators: hemoglobin (Hb), serum ferritin (SF), serum transferrin receptor (sTfR), and body iron index (mg/kg). Severe anemia among the women from southern Bulgaria was not observed. Advanced pregnancy and some eating habits are factors that deteriorate iron status. Women who had consumed fish at least 3 times a week had lower levels of sTfR (р = 0.008), higher levels of SF (р = 0.05), and lower levels of body iron (р = 0.018). Frequent legume consumption was related to increased levels of sTfR (р = 0.036). Pregnant women with a high frequency of coffee consumption had lower values of body iron (р < 0.0001). Women who had consumed cow's milk at least 3 times a week had lower levels of SF (р = 0.026) and body iron (р = 0.042). Regular consumption of fish and legumes, rarely drinking coffee, and milk consumption during the intervals between food intake are conditions for optimization of iron status during pregnancy.

Challenges to orphan drugs access in Eastern Europe: the case of Bulgaria.

This article explores how an Eastern European country could deal with orphan drugs access, combining EU policies with its own national settings. The cross-sectional observational study takes the total number of orphan drugs (61) available on EU level by March 2011, and then consecutively filters it through the requirements and criteria of relevant Bulgarian legislation on registration, pricing and reimbursement of medicinal products, obtaining the final number of accessible orphan drugs (16) in Bulgaria. The study further evaluates the average time period from market authorisation to positive reimbursement decision by Bulgarian health authorities (43±29.1 months). Access to orphan drugs should be provided on a reasonable and justified basis. Having in mind the limited availability of resources, it is not a question whether to prioritise rarity, but to create legitimate mechanisms for properly assessing orphan drugs' value and optimally using this value, according to the society's needs and views. The analysis identifies four important challenges to orphan drugs' access in Eastern Europe: (1) elaboration of new orphan drugs pricing approaches, (2) further interaction of cost-effectiveness analysis with medical criteria, (3) active introduction of epidemiological registries for rare diseases, and (4) research of societal preferences and raising public awareness.

Vaya (Ramsar site, protected area and Natura 2000 site) is the biggest natural lake in Bulgaria and the shallowest Black Sea coastal lake, which during the last decades has undergone significant changes and was included as critically endangered in the Red List of Bulgarian Wetlands. Our studies were conducted during the summer and autumn months of three years - 2004-2006. The paper presents results on the phytoplankton abundance (numbers, biomass and carbon content) in combination with the indices of species diversity, evenness and dominance. Phytoplankton abundance was extremely high (average values of 1135 × 10 6 cells/L for the quantity and of 46 mg/L for the biomass) and increased in the end of the studied period (years 2005-2006), when decrease of species diversity and increase of the dominance index values were detected. The carbon content of the phytoplankton was at an average value of 9.7 mg/L and also increased from 2004 to 2006. Cyanoprokaryota dominated in the formation of the total carbon content of the phytoplankton, in its numbers (88%-97.8%), and in the biomass (62%-87.9%). All data on phytoplankton abundance and structural parameters in Vaya confirm the hypertrophic status of the lake and reflect the general negative trend in its development.

Changes of erythrocyte-metric parameters in Pelophylax ridibundus (Amphibia: Anura: Ranidae) inhabiting water bodies with different types of anthropogenic pollution in Southern Bulgaria.

The article presents the basic erythrocyte-metric parameters: cell length (EL) and width (EW), EL/EW, erythrocyte size (ES), nucleus length (NL) and width (NW), NL/NW, nucleus size (NS) and nucleocytoplasmic ratio (NS/ES) in the wild populations of marsh frogs Pelophylax ridibundus from five water bodies in Southern Bulgaria (two rivers and three reservoirs) with different degrees and types of anthropogenic pollution (less disrupted water basins, domestic sewage pollution and heavy metal pollution). The changes in erythrocyte-metric parameters depend on concentrations and types of toxicant and, to a lesser extent, on the type of water basin. We found that when P. ridibundus populations live in conditions of domestic sewage pollution, EL, EW and ES increase in comparison with the control samples, with regard to an elongated elliptical cell shape. Simultaneously, NL, NW and NS did not undergo any significant changes when compared with the control samples. The nuclei had elliptical shape. In the populations from the water basins with heavy metal pollution, EL, EW, ES, NL, NW and NS decreased. The cells and nuclei had a circular shape. NS/ES decreased when compared with the control sample, regardless of the type of toxicants.
