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

    Full Text Available While hunting in traditional societies, was most commonly practised as a profession, for food, sports or entertainment, it was fully a part of Ottoman State organization as a military exercise or war game. From the first Ottoman rulers, there has been hunting institution in the palace. An organized hunting institution, regular hunting practices and the number of hunted animals had been perceived as the symbols of power of the ruler. Hunting organization was instrumental in identifying the situations of the country and people, inspecting government officials and listening to people’s problems. In this respect, the meaning of hunting ceremony gains great importance. Hunting bird-growing organization in Ottoman Empire palace had been institutionalized since early years. Its provincial administration was created for particular sanjaks. The structure of provincial hunting organization was organized in the form of taşra doğancıları (provincial falconers or hawkers, sayyad (hunters, yavrucu (fledgeling careres, yuvacı (nest carers, kayacı (carer of nest rocks, görenceci (bird observers, tuzakçı (bird catchers. There are records in Ottoman archives about this units concerning their organization, numbers, how they were spread and how the duties were passed from father to son. In this study, in the 16th century provincial Ottoman hunting organization and services in Silistra has been throughly examined, using archive documents.

  3. Coal in Bulgaria

    Energy Technology Data Exchange (ETDEWEB)

    1999-01-01

    Bulgaria`s national energy strategy includes plans to restructure the energy sector by introducing competition and privatisation, to promote energy efficiency and environmental protection and to prepare the country for integration into the EU energy market. Energy prices are still under government control and coal mining is heavily subsidised. Bulgaria is a major producer of coal, all of which is consumed locally. Most of the domestic production is low quality lignite used for electricity generation. Demand for hard coal is met by imports, mainly from the former USSR and the USA. Bulgaria generates almost half of its electricity needs from coal. Total reserves of lignite are estimated at 2.5 Gt. Coal production declined between 1987 and 1991 reflecting the economic disturbance following the break up of the USSR. In 1996, production was 32 Mt. The mining industry is being restructured as Bulgaria is slowly moving from a centrally-controlled economy to a market-based economy. Environmental damage as a result of coal production has been serious in Bulgaria, due to the use of low grade high sulphur content lignite. 84 refs., 10 figs., 9 tabs.

    We present a summary of the mineralogy, mineral chemistry, and magnetic characteristics of all the five Bulgarian meteorite falls. We report the first mineralogical descriptions, chemical analyses, and magnetic measurements of the Konevo (1931) and Silistra (1917) meteorites. We classify Konevo as LL5, and Silistra as an ungrouped achondrite with HED affinities. Pavel (1966; previously classified as an H5) is reclassified as H3-anomalous. We also provide precise mineralogy and mineral chemistry of the Virba meteorite (1873, L6), and more details on the mineral chemistry of Gumoschnik (1904, H5).

    The transplantation program in Bulgaria started in 1968 with renal transplantations to a child and adult woman. In 1986 the first heart transplantation was performed. To date a total of 10 heart transplants have been performed, including one combined heart/lung. A liver transplantation program was launched in 2005 with a total number of 16 transplantations-7 from living donors and 9 from deceased donors. The highest transplantation activity is registered in the field of renal transplantation. During the period 1980-2006, 462 Bulgarian recipients of kidney were transplanted in Bulgaria. The ratio between transplantations from deceased and living related donors is approximately 1:0.9. Annual transplantation activity varies among the years from 1 to 12 renal transplantations p.m.p./per year. The 1- (80.7% vs. 63.1%), 5- (57.86% vs. 39.0%) and 10-year (42.65% vs. 23.62%) graft survival rates are higher for recipients of living donor kidneys compared to those of deceased donor. In 1983 a National kidney waiting list was established. Currently the number of the registered patients eligible for renal transplantation is 885. The proportion of sensitized patients in the waiting list is 20.45% and 4.34% of them are hyperimmunized. Recently HLAMatchmaker program has been implemented not only for sensitized patients but also for those with rare alleles and haplotypes. Post-transplant immunological monitoring showed a strong association between alloantibody presence and delayed graft function (Chi-square=10.73, P<0.001), acute rejection (Chi-square=14.504, P<0.001), chronic rejection (Chi-square=12.84, P<0.001) and graft loss (Chi-square=20.283, P<0.001). Based on the experience in our transplant center a strategy for improvement of long-term renal graft survival was developed and implemented.

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

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

  16. Circulation factors affecting precipitation over Bulgaria

    Nojarov, Peter

    2017-01-01

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

    D. Solakov

    1999-06-01

    Full Text Available We apply statistical analysis to study the temporal distribution of aftershocks in aftershock sequences of five earthquakes which occurred in Bulgaria. We use the maximum likelihood method to estimate the parameters of the modified Omori formula for aftershock sequences which is directly based on a time series. We find that: the maximum likelihood estimates of the parameter p show a regional variation, with lower values of the decay rate in North Bulgaria; the modified Omori formula provides an appropriate representation of temporal variation of the aftershock activity in North Bulgaria; the aftershock sequences in South Bulgaria are best modeled by the combination of an ordinary aftershock sequence with secondary aftershock activity. A plot of the cumulative number of events versus the frequency-linearized time t clearly demonstrates a transition from aftershock to foreshock activity prior to the second 1986 Strazhitsa (North Bulgaria earthquake.

    The marketing management includes analysis of market opportunities, selection of target markets, planning, developing and implementing of marketing strategies, monitoring and result control. The object of the present study was to analyse the marketing approaches applied for non-steroidal anti-inflammatory drugs (NSAIDs) in Bulgaria. The performed SWOT(planning method used to evaluate the strengths, weaknesses, opportunities, and threats) analysis for one of the leading Bulgarian manufacturers marked the complex corporative strategy for stimulating the sales of NSAIDs. The study results show that the legislation frame in the country gives an opportunity for regulation of the NSAID market in order that incorrect marketing approaches such as disloyal competition are avoided.

    We use a coupled atmosphere-fire model to simulate a fire that occurred on August 14--17, 2009, in the Harmanli region, Bulgaria. Data was obtained from GIS and satellites imagery, and from standard atmospheric data sources. Fuel data was classified in the 13 Anderson categories. For correct fire behavior, the spatial resolution of the models needed to be fine enough to resolve the essential micrometeorological effects. The simulation results are compared to available incident data. The code runs faster than real time on a cluster. The model is available from openwfm.org and it extends WRF-Fire from WRF 3.3 release.

  11. The story of a 'maverick': Bulgaria's fertility decline.

    Analysis of the fertility decline in Bulgaria shows that the perception of Bulgaria as an 'anomaly' in terms of its demographic development is based on a conservative interpretatiion of the demographic transition theory. The features that distinguish Bulgaria from the western European countries (faster decline, persistence of early and universal marriages, etc.) are generally accounted for by the specific social, economic, cultural, and political conditions. These findings suggest that the speed of the fertility decline and the means through which it is achieved are affected by a complex interaction between cultural and economic factors that are often difficult to distinguish in terms of primacy.

    Full Text Available The image of the country can be influential in various buying decisions, especially in cases where there is a strong competition among market players and if price is not the factor with the utmost importance. In a psychosemantic experiment we study the demand patterns for imported goods in Bulgaria. We aim to assess how Bulgarian citizens build their image of other countries, especially the neighbour ones. We find that “market dimension” and “power dimension” are the major factors in the perceptions. We find also that perceptions of Bulgarian respondents give a more important role in Bulgarian economy to globally more important economies, despite the vicinity of neighbour countries.

    Full Text Available The paper presents the results of studies on the qualitative and quantitative features of the littoral drift at Golden Sands (Bulgaria, carried out jointly by Polish and Bulgarian researchers. The mathematical modelling of physical coastal processes took wave transformation (wave diffraction and refraction; the effects of shoaling and wave breaking and longshore sediment transport into account. The computations were carried out for the mean statistical annual wave climate, determined on the basis of IO BAS wave data, simulated using the WAM method from long-term Black Sea wind data. The results of sediment transport computations clearly show that its direction off the Golden Sands shore is from north to south.

    The marketing management includes analysis of market opportunities, selection of target markets, planning, developing and implementing of marketing strategies, monitoring and result control. The object of the present study was to analyse the marketing approaches applied for non-steroidal anti-inflammatory drugs (NSAIDs) in Bulgaria. The performed SWOT(planning method used to evaluate the strengths, weaknesses, opportunities, and threats) analysis for one of the leading Bulgarian manufacturers marked the complex corporative strategy for stimulating the sales of NSAIDs. The study results show that the legislation frame in the country gives an opportunity for regulation of the NSAID market in order that incorrect marketing approaches such as disloyal competition are avoided.

    2016-06-01

    Full Text Available Our time is marked by the increasingly dynamic changing environment. The new conditions in which we operate are characterized by increasing complexity and labor activities that require more responsible behavior. The rising levels of stress and the increasing lack of free time for relaxation and recreation require a new look at the possibilities for the prevention of personal health. The plane of the consumer society in which we live is increasingly shifted by aspiration and vision of an environmentally friendly lifestyle. The focus here is the implementation of a multilevel wellness concept that changes qualitatively the status quo and seeks for ways to harmonize the body with the nature. One of the options is the practice of SPA tourism in whose genesis is the multilayered beneficial impact of a series of procedures and actions. This new alternative through its economic dimensions is an attractive business niche which over time becomes an industry. The current state of the SPA tourism in Bulgaria is controversial despite existing achievements and introduced best practices. Traditions in this direction and the presence of favorable basis for its approval, however, are not sufficient to achieve stability and an upward trend in development. There are existing a number of weaknesses and negative aspects that create frustration in users, which is a real threat to its future. The proposed SWOT-analysis as part of a comprehensive and multilateral study of the state of SPA tourism in Bulgaria reveals some of the existing problems. There have been some suggestions to minimize the impact of weaknesses and eliminate the errors found in leading business organizations managing processes. A detailed analysis and evaluation of the formulated conclusions is ahead, as well as concluding on ideas to improve the state of the sector – a subject of a further investigation by the author.

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

    The filed of liver transplantation (LT) continues to evolve and is highly effective therapy for many patients with acute and chronic liver failure resulting from a variety of causes. Improvement of perioperative care, surgical technique and immunosuppression in recent years has led to its transformation into a safe and routine procedure with steadily improving results. The aim of this paper is to present the initial experience of the transplant team at Military Medical Academy - Sofia, Bulgaria. For the period of April 2007 - August 2014 the team performed 38 liver transplants in 37 patients (one retransplantation). Patients were followed up prospectively and retrospectively. In 36 (95%) patients a graft from a cadaveric donor was used and in two cases--a right liver grafts from live donor. The mean MELD score of the transplanted patients was 17 (9-40). The preferred surgical technique was "piggyback" with preservation of inferior vena cava in 33 (86%) of the cases and classical technique in 3 (8%) patients. The overall complication rate was 48%. Early mortality rate was 13% (5 patients). The overall 1- and 5-year survival is 81% and 77% respectivelly. The setting of a new LT program is a complex process which requires the effort and effective colaboration of a wide range of speciacialists (hepatologists, surgeons, anesthesiologists, psychologists, therapists, coordinators, etc.) and institutions. The good results are function of a proper selection of the donors and the recipients. Living donation is an alternative in the shortage of cadaveric donors.

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

    Full Text Available Generic medicines play a key role in managing the financial resources for pharmaceuticals in every country. This study analysed the generic policy legislative framework in Bulgaria with the aim to identify whether the policy implementation can be considered successful in the light of an international review of such policies introduced in other countries, or on the contrary, it has failed to deliver the main benefits. Legislative analysis, desktop study and macroeconomic overview of the Bulgarian pharmaceutical market were included. The study showed that only 3 out of 11 important policy elements are implemented in the country. Bulgaria has one of the highest shares of generics, an average of 81.39% (volume, for the studied period (2006–2014. However, further research is needed to evaluate the success of the existing generic policy in Bulgaria, as the market share of generic drugs is not the only measure of the policy efficiency.

    Full Text Available The aim of the recent study was to trace back the development of the donkey population in Bulgaria for the period 1950 – 2015. For that purpose the data from the National Statistic Institute and FAO was processed and other sources related to the problem were analyzed. Donkeys in Bulgaria used to be a comparatively large share of the traction power animals in the past, with the occurance of the social and economical changes after 1990 their number was dramatically reduced. This process is most noticeable after 2000, when for five year period until 2005 the donkey population in Bulgaria drops down from 207000 to 90000 individuals, as in 2013 this number falls down to 35000 according to FAO.

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

    Full Text Available The purpose of this article is to follow trends in the development of organic farming in Bulgaria, and to identify the factors’ strength and direction of their impact on organic production of agricultural products. The study covers the period from 2003 to 2013 and is based on information from official statistics of the Ministry of Agriculture and Food, and the author's own research. There are distinct rates of increase in both areas and organic agricultural production in Bulgaria. While in 2003 the areas under organic management are 8,364 ha by 2013 they numbered 56, 287 ha. Bulgaria has a high potential for production and export of organic agricultural products fresh and processed, but significantly lags behind other European countries. However, there is increasing momentum in organic farming, driven by a group of economic, market, social and legislative initiatives. The main reason for this growth is consumer demand of organic products in Bulgaria. In general, the motivations of Bulgarian consumers of organic products are related to the benefits for health and the environment, to the improvement of food quality and to the support of local small farmers, communities and markets.

    Kruczyk, J.; Kaḑziałko-Hofmokl, M.; Nozharov, P.; Petkov, N.; Nachev, I.

    Paleomagnetic investigations were performed on Jurassic sediments sampled in the mobile area of Bulgaria comprising Srednogorie, Kreiste and Stranja. The main carriers of magnetic properties of rocks studied are pigmentary haematite and goethite of post-sedimentary origin. The characteristic component of natural remanence (CARM), isolated by means of analysis of demagnetization procedure is secondary, and was acquired after the main tectonic event that took place in this area during the Upper Cretaceous. The CARM directions before tectonic correction are close to the results for Upper Cretaceous magmatic rocks from Srednogorie. The mean CARM direction and the corresponding polar position obtained for the whole region studied are compared with reference data for the Eurasian Platform. The difference between the reference and our data implies anticlockwise rotation of southern Bulgaria relative to Eurasia by ˜ 10-20° and a northward tilt of the region under study by ˜ 10-15° after acquisition of CARM.

    Full Text Available BACKGROUND: Sleep disturbance is a risk factor for somatic, psycho-social and spiritual dysfunction. It is also arguably the most deleterious effect of traffic noise pollution. Quantification of its burden is an anchor element of environmental policy making but no data are currently available for Bulgaria where the preponderance of dangerous nighttime noise exposure is highest in Europe. AIM: The aim of this study was to quantify the socio-economic burden of severe sleep disturbance due to traffic noise (road, aircraft and railway in Bulgaria. MATERIAL AND METHODS: The official World Health Organization methodology used in Europe was applied in order to estimate this annual loss expressed as disability-adjusted life-years (DALYs and their corresponding monetary value (assuming € 12 000 per DALY. RESULTS: Results showed that severe sleep disturbance due to all traffic sources was associated conservatively with 15 468 DALYs (8 839 - 22 097 and € 185 615 861 (€ 106 066 206 - € 265 165 516 lost in 2012, with road traffic being the single most important noise source. CONCLUSION: In conclusion, severe sleep disturbance due to traffic noise bears a heavy environmental and socio-economic burden in Bulgaria which prompts vigorous political action and greater involvement in environmental research. In order to increase the accuracy of future burden of disease analyses other studies would need to establish exposure-response functions based on population-based socio-acoustic surveys in the country.

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

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

    Full Text Available The paper examines the strategies of young people in Bulgaria for responding to and dealing with uncertainty in the passage to autonomy. It focuses on the active engagement of the young in the processes of identity formation and gaining independence, thus initiating a change in the common patterns of growing up. The biographical choices that the young make are analysed as embedded in a multilayered social context involving the interplay of macro societal changes, shifts in organisational policies and practices and restructuring of gender and generational relations in the family. Theoretically this paper builds upon the concept of uncertainty in understanding the dilemma of structure and agency in youth transitions. The analysis is based upon official statistical information about economic and demographic trends in 21st century Bulgaria and the findings of an organisational case study of a social service agency and biographical interviews with young working parents, which were conducted within the framework of the international Transitions project. Two case studies of individual strategies of young women - one from a working class family and the other from an ethnic minority - are presented in more detail in order to examine the agency they apply in coping with uncertainty and the resources they mobilize in devising (everyday and short-term life projects. The combination of quantitative and qualitative data allows a reflection on the process of managing uncertainty with regards to the past experiences, present meanings and future aspirations of young people as influenced by the contracting state support and contradictory company policies in Bulgaria.

    2016-10-01

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

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

    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.

    Human trichinellosis is a major food-borne zoonosis in Bulgaria with a high health, social, and economic impact. Every year outbreaks and sporadic cases are registered in the country. Epidemiological data based on standard protocols for epidemiological surveillance and control of human trichinellosis for each region in the country were collected and analysed at the National Centre of Infectious and Parasitic Diseases, and the main epidemiological trends during the past 17 years (1990-2006) were determined. Since 1991 human trichinellosis has become a re-emerging zoonosis in Bulgaria. A total number of 145 trichinellosis outbreaks and 238 sporadic cases were registered. Altogether, 7544 persons have consumed meat or meat products harbouring Trichinella larvae, and of these, 4108 individuals (54.45%) contracted trichinellosis (with 2 deaths). The annual incidence of human trichinellosis varied from 0.27 to 7.40 per 100,000 population. Fifty-seven of the outbreaks were sourced to wild boar meat consumption, 67 were due to consumption of pork products, and in 21 outbreaks the source of infection was unidentified (4 of them were associated with consumption of mixed meat--pork and wild boar meat products). The peaks of outbreaks (12 per year) were registered in 1994, 1998, 2002, and 2003. In recent years some decrease in the numbers of outbreaks was observed (2004: 6, 2005: 3, and 2006: 7).

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

    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.

    As a part of the systematic survey of indoor radon in Bulgaria, the indoor radon concentration was measured in 296 kindergarten buildings of Sofia city during 3 months (February to April 2013) using the CR-39 nuclear tract detectors. In 256 buildings at least two frequently occupied rooms (mainly playrooms) were observed. Altogether, 922 measurements were performed. The frequency distribution was well described by the lognormal function. The measured radon concentrations range between 9 and 1415 Bq m(-3) with a geometric mean of 101 Bq m(-3) (2.08) and an arithmetic mean 132 Bq m(-3) with a standard deviation of 118 Bq m(-3). The radon concentrations obtained in this survey were compared with that in Sofia city dwellings obtained from a previous study. A detailed statistical analysis of the building factors was presented.

    Full Text Available In recent years there has been a great interest among manufacturers to conventional and organic production of walnuts. Currently Bulgarian market has over 500 walnut producers and about 30,000 acres of industrial walnut orchards. Suitable areas for growing walnuts in Bulgaria are Plovdiv, Pazardzhik, Stara Zagora, Haskovo, Shumen and Razgrad, as most industrial plants are in Stara Zagora, Plovdiv, Pleven and Haskovo. The market for walnuts in Europe is virtually limitless, since about 100 thousand tonnes per year are imported, mostly from the US. Walnuts growing is a profitable business and an excellent long term investment. The return of the investment depends mainly on the choice of locally relevant varieties.

    Full Text Available Over the recent years the climate extremes like as drought and floods become more often and have negative impact on human society. That is way it is very important to know the peculiarities of precipitation variability. The paper investigates precipitation variability during summer time in one of the most important agriculture region in Bulgaria - Danube Plain. The summer-time is determined for the period May - October. The study is based on monthly precipitation total for the period 1961-2005. The precipitation variability is analyzed by comparison with the period 1961-1990, determined by World Meteorological Organization as "contemporary climate". In order to investigate the precipitation variability the various indices lake as Percent of Normal, Rainfall Anomaly Index and Cumulative Anomaly have been calculated. Two wet spells (1865-1983 and 1993-2005 and one dry spell (1983-1993 have been identified. The Kriging interpolation has been applied for presenting special distribution of precipitation variability.

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

    2012-06-01

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

    The purpose of the study was to identify the basic epidemiological characteristics of burn patients in East Bulgaria, as well as to analyze trends in burns in the region over the last decade. Retrospective data of burn patients treated at Military Hospital-Varna, in the period January 2002-December 2011, was reviewed and statistically interpreted in terms of patients and burn demographics; etiology; place of incidents; hospital stay and mortality. Trends were observed for the entire period and comparative analyses of patients' data were made between two periods: first - 2002-2006 and second 2007-2011. A total of 2627 burn patients, median age 41 years (IQR 9-61) were admitted to our burn unit. For the entire period the most affected age groups were ≤ 4 years (21.6%) and ≥ 65 years (21.1%). Hospitalized patients increased in the second period (n = 1701) compared to the first one (n = 926), while the size of total burn surface area decreased (first period - 9.8% vs. second period - 10.6%). Scald (51%) and flame (23.8%) were the most frequent aetiological agents for both periods. Work related burns reduced in the second period (9.4% vs. 4.9%), while home burns (90.6 vs. 95.1%) increased. Hospital stay declined from 17 days (2002-2006) to 7 days (2007-2011), whereas mortality rate slightly increased (first period - 2.3% vs. second period - 3.6%). Burns remain a significant health problem in Bulgaria. The future preventive actions should take into account the observed changes in burn demographics and target the most vulnerable groups.

    2017-05-01

    Full Text Available Tobacco industry (TI has a powerful grasp of politics and the media in Bulgaria, but there is limited knowledge of its methods and communication messages. To explore and analyse them, we are using a recent case from the policy advocacy practice of the Smoke-free Life Coalition, ENSP member in Bulgaria. A mixed social research methodology was employed, involving: a case study; qualitative content analysis of documented communication; ethnographic participant observation; and semi-structured interviews with TAPS advocacy campaigners, policy makers and TI representatives, in the action research tradition. The case study analyses TI reaction to a surprising proposal for a complete ban of tobacco advertising, promotion and sponsorship, submitted to Bulgaria’s Parliament in November 2016 – and consecutively withdrawn. Being involved in all stages of the case and present at meetings between TI and MPs enables the researchers to gather rich information and analyse it, to cast light on: the methods for successful interference with democratic decision making, applied by industry representatives; the specific communication messages and arguments they employ to suppress smoke-free legislation. The paper observes how TI speculates with the interests of different groups, affected by and involved in its operations, to successfully contradict health concerns voiced by MPs. Democratically elected representatives appear unable to uphold the social and health interests of their voters and succumb to TI priorities. The paper concludes that a pro-industry discourse, which favours corporate incomes over concerns for people’s health and life, dominates democratic decision making mechanisms in Bulgaria’s post-socialist political landscape.

    2011-12-01

    This synthesis paper explores current leadership training in science, technology, engineering and mathematics (STEM) education in Bulgaria. The analysis begins with discussion of global factors influencing the implementation of leadership training in STEM education in general and then presents information about the current status of leadership training in Bulgaria with emphases on the country's economics, politics and geographical location as specific factors influencing leadership education. A short background of Bulgaria is presented with regard to population, gross domestic product, educational system, engineering force and possible need for leaders in industry in Bulgaria and the European Union. The paper provides an overall view about the current status of leadership training in all Bulgarian universities offering STEM education and concentrates specifically on two major universities by examining their currently offered programmes. As part of the discussion, similar training elements in other European countries and the USA are presented.

    2014-03-04

    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.

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

Particular attention is given to the diplomatic conflict between Bulgaria and the Balkans, and the role of Bulgaria in the conflict. Emphasizes the controversial policy of Bulgaria, which is quite evasive and carefully behaved on the eve of global conflict. It is noted that the beginning of the military conflict in Europe automatically done Bulgarian revisionist foreign policy revanchist policy. The fact that the Bulgarian national question was also a territorial issue. Bulgaria had a claim to almost each of its four neighbors. Diversity its revisionism would cause significant difficulties in any major state or coalition of states that have set a goal of attracting Bulgaria as an ally. It is noted that the definition of Bulgarian foreign policy concept of the crucial role played by King Ferdinand. «All Bulgarian political life, especially foreign policy, guided by the king, - said the Russian envoy in Sofia AA Savinskyy. - Ministers are blind instrument in his hands.» [5, P. 741-742]. It is noted that at the beginning of the first World War Macedonian lands were subject to bargaining between Bulgaria and the Entente, on the one hand and the Central Powers - on the other. For entry into the war both coalition promised Sophia accession Vardarskoyi and the part of Aegean Macedonia. Bulgaria’s main mistake was that it entered the World War on the side not to «friends» and to the side of the oppressor century of Bulgarian land - of the Ottoman Empire. The article was followed that liberated severe suffering, Bulgaria passed to the enemy, seeking «justice.» This step was considered by public opinion as «ingratitude» and under the authority of Bulgaria fell more.

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

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

    Science.gov (United States)

    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

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

  1. Tourism Competitiveness Index – An Empirical Analysis Romania vs. Bulgaria

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

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

    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.

The aim of the study was to determine the species composition of small lungworms in these hosts. The obtained results are summarized with those of previous studies, and a picture of the present status of the species composition of protostrongylids in ruminants from Bulgaria is forwarded. Morphometric data about the species Muellerius capillaris, Cystocaulus ocreatus, Neostrongylus linearis, Protostrongylus brevispiculum, and Protostrongylus rufescens are presented. The data on the morphology of these five species are supplied for the first time both for Bulgaria and the south-east part of the European continent.

    1996-12-31

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

  9. UNMET NEEDS FOR HEALTH CARE SERVICES IN BULGARIA

    Directory of Open Access Journals (Sweden)

    Elka Atanasova

    2016-09-01

    Full Text Available Background: In all European countries, an important policy objective is the equity of access to health care. The factors that affect access to health care can differ as the demand- and supply-side factors. Moreover, there are many tools to assess the extent of inequity in access to services. One simple tool is the assessing reports of unmet needs for health care. Purpose: The study has two objectives: to examine the evidence of self-reported unmet needs and to analyze the relationship between foregone medical care and both type of residence and socioeconomic status. Materials and Methods: We use data from the European Union Statistics on Income and Living Conditions. The access to health care is measured using the concept of unmet need for medical examination or treatment during the last 12 months. The relationship between foregone medical care and both type of residence and socioeconomic status is examined through the representative survey conducted in 2014. Results: The Eurostat results show that treatment costs are the most common reason for foregone medical care in Bulgaria. We observe a gradual decrease in the share of people who reported having unmet needs due to being too expensive. According to the 2014 survey, significant differences between urban and rural areas as well as among the income groups are identified. The results show the problems in access to health care services mainly in small towns and villages. Conclusion: Although major essential changes were made in the Bulgarian health care system, the equity problems remain an important challenge to policy-makers.

    During the ongoing rotavirus strain surveillance program conducted in Bulgaria, an unusual human rotavirus A (RVA) strain, RVA/Human/BG/BG620/2008/G5P[6], was identified among 2200 genotyped Bulgarian RVAs. This strain showed the following genomic configuration: G5-P[6]-I1-R1-C1-M1-A8-N1-T1-E1-H1. Phylogenetic analysis of the genes encoding the neutralization proteins and backbone genes identified a probable mixture of RVA genes of human and porcine origin. The VP1, VP6 and NSP2 genes were more closely related to typical human rotavirus strains. The remaining eight genes were either closely related to typical porcine and unusual human-porcine reassortant rotavirus strains or were equally distant from reference human and porcine strains. This study is the first to report an unusual rotavirus isolate with G5P[6] genotype in Europe which has most likely emerged from zoonotic transmission. The absence of porcine rotavirus sequence data from this area did not permit to assess if the suspected ancestral zoonotic porcine strain already had human rotavirus genes in its genome when transmitted from pig to human, or, the transmission was coupled or followed by gene reassortment event(s). Because our strain shared no neutralization antigens with rotavirus vaccines used for routine immunization in children, attention is needed to monitor if this G-P combination will be able to emerge in human populations. A better understanding of the ecology of rotavirus zoonoses requires simultaneous monitoring of rotavirus strains in humans and animals.

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

    2014-05-01

    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.

    1982-01-01

    Problems arising in the use of wind energy on a significant scale are discussed, and the progress made in this area in Bulgaria is summarized. On the basis of calculations of the wind-energy distribution on Cape Kaliakra in Bulgaria, the wind-energy resources in this region are compared with the findings of Kiuchukova and Ivanov (1975). It is shown that whereas conditions exist in the country for using wind energy on a large scale, the meteorological network does not encompass all the suitable regions. A method of finding places suitable for exploitation is outlined. The method involves both numerical evaluations and observational tests.

This led to an annual increase in the expenditures on drug products for home treatment (on average, 17% for the period 2009-2012. Conclusion: This trend in Bulgaria will continue in the future since expenditure control only through price control by means of a reference system and the positive list of medicines is ineffective. There is a need for implementation of combined drug policies in Bulgaria in the form of negotiations on rebates with manufacturers and agreements on controlled access of patients and reference pricing.

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

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

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

    Directory of Open Access Journals (Sweden)

    Vesselin Dimitrov

    2000-01-01

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

    2015-05-01

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

  20. Porphyry-copper mineralisation in the central Srednogorie zone, Bulgaria

    The porphyry-copper systems in the central part of the Srednogorie zone (Bulgaria) are represented by three major deposits (Elatsite, Medet and Assarel) and several smaller deposits and occurrences, all of them within the Panagyurishte ore district. The hydrothermal systems are related to Late Cretaceous calc-alkaline igneous complexes. Ore mineralisation is developed predominantly in the apical parts of subvolcanic and intrusive bodies as well as within the volcanic and basement metamorphic rocks. Several of the porphyry systems are spatially associated with shallow-level intermediate and high-sulphidation volcanic-hosted epithermal deposits of economic importance, such as the major gold-copper mine at Chelopech located 10 km from the Elatsite porphyry-copper deposit. Mineralisation processes in the porphyry deposits start with intensive hydrothermal alteration of the wall rocks. K-silicate alteration is characteristic for pre-ore hydrothermal activity in all of them, and it is located mostly in their central parts. Propylitic alteration is prominent in the Medet and Assarel deposits. The Assarel deposit is located in the central part of a palaeovolcanic structure and shows a large spectrum of pre-ore alterations, including propylitic, sericitic, and advanced argillic assemblages. The initial stages of the hydrothermal systems are characterised by high temperatures (>550-500 °C) and highly saline (50-20 wt% NaCl equiv.) and vapour-rich fluids of likely magmatic origin. The composition of the fluids gradually changes from H2O-NaCl±FeCl2 to H2O-NaCl-KCl and H2O-NaCl-dominated as the fluids cool, react with wall rocks, and may become diluted with meteoric water. Fe-Ti-oxide mineral associations were formed early in all deposits, later followed, in the Elatsite deposit, by an assemblage of bornite, chalcopyrite, platinum group element (PGE) phases, Co-Ni thiospinels, Ag- and Bi-tellurides, and selenides. The main ore stage in all deposits is dominated by

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

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

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

    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

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

    Holleran, Max

    2014-03-01

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

    An EU twinning project entitled 'Strengthening of administrative structures for radiation protection and safe use of ionising radiation in diagnostics and therapy' was established between Bulgaria and Finland, lasting from June 2008 to May 2009. One component of the project was to improve the optimisation of patient protection in nuclear medicine (NM) through revising diagnostic reference levels (DRLs). The revised DRLs are based on national surveys on the numbers of NM procedures and activities given to the patients in different procedures. The survey in Bulgaria was carried out in 2008 and that in Finland in 2007. National DRLs were established for the most frequent and dose-relevant examinations. The proposed DRLs in both countries are in good agreement with other national recommendations in Europe.

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

    One of the traditional ways of preparation of yogurt starter in Bulgaria is placing a branch of a particular plant species into boiled sheep's milk maintained at about 45 degrees C, which is further incubated until a dense coagulum is obtained. To investigate the possible origin of the yogurt starter bacteria, Lactobacillus delbrueckii ssp. bulgaricus (L. bulgaricus) and Streptococcus thermophilus (S. thermophilus), the traditional way of yogurt-starter preparation was followed. Hundreds of plant samples were collected from four regions in Bulgaria and incubated in sterile skim milk. The two target bacteria at low frequencies from the plant samples collected were successfully isolated. Phenotypic and genotypic characteristics of these bacterial isolates revealed that they were identified as L. bulgaricus and S. thermophilus. Twenty isolates of L. bulgaricus and S. thermophilus, respectively, were selected from the isolated strains and further characterized with regard to their performance in yogurt production. Organoleptic and physical properties of yogurt prepared using the isolated strains from plants were not significantly different from those prepared using commercial yogurt-starter strains. It was therefore suggested that L. bulgaricus and S. thermophilus strains widely used for commercial yogurt production could have originated from plants in Bulgaria. To our knowledge, this is the first report on the isolation and characterization of L. bulgaricus and S. thermophilus strains from plants.

    Full Text Available Effective management of water resources requires adequate knowledge of groundwater system including the influence of climate variability and climate change. The drought of 1982-1994 in Bulgaria has led to important decrease of springflow and lowering of water levels. Therefore, groundwater demonstrated its vulnerability to drought. The purpose of this paper is to determine relative resistance of selected aquifers in Bulgaria to a prolonged decrease of recharge to groundwater. The drought resistance indicator has been defined for some karstic aquifers based on the method proposed in report of BRGM. The data from National Hydrogeological Network located in the National Institute of Meteorology and Hydrology were processed. For the aim of this study, time-series of discharge for karstic springs were used. Stations with significant impact of human activity on groundwater were eliminated. The results show that most of studied aquifers in Bulgaria have moderate and weak resistance to the drought. They are vulnerable to droughts and need good management for effective use of groundwater resources.

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

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

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

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

    The National registry of patients with neuroendocrine tumors (NET) in Bulgaria was established in 2013 as a joint initiative of the Bulgarian Surgical Society and the Institute for Rare Diseases. The register aims to explore the epidemiology of NET in Bulgaria, as well as the different diagnostic and treatment approaches for the disease throughout the country. This the first of its kind retrospective study of NET in the country is covering the period January 2012 - January 2013. A total of 127 patients with NET were identified. At the time of the survey the average age of patients with NET was 58.61 ± 15.59 years. The data show almost equal distribution between the genders with a slight predominance of women. The largest relative part of NET is those of NET located in the gastrointestinal tract (54.10 ± 4.51%), followed by those located in the pancreas (12.30 ± 2.97%) and in the lungs (10.66 ± 2.79%). In 72.44 ± 3.96% of the patients a immunohistochemical diagnosis was performed. The study confirmed the leading role of the surgery method of the NET management. In 65.83 ± 4.33% of the patients a radical removal of the tumor was conducted, while the relative part of the undertaken partial resection was 7.50 ± 2.40%. A statistically significant association between the type of surgical treatment and during the follow-up of patients was found. An update of the information in the register will allow a more precise determining of the distribution and management of NET in Bulgaria.

    Full Text Available Colletotrichum coccodes has been recognized as one of the causal agents of pepper fruit anthracnose in Bulgaria. Recently, this species has been recorded in pepper fruits in Macedonia. In Bulgaria, the fungus has also been isolated from roots of premature senescent pepper plants but in Macedonia it has not been isolated yet. The purpose of the investigation was to make comparative morphological, cultural and molecular characterization of C. coccodes isolates obtained from pepper fruits and roots in Bulgaria and Macedonia. Additionally, a technique was applied to differentiate among the C. coccodes isolates obtained from roots and other microsclerotia-producing fungi. On the host tissue, C. coccodes developed acervular conidiomata with cup-shaped fruiting bodies accompanied with dark-pigmented, unbranched, thick-walled sterile hyphae called setae. A slimy mass of hyaline, straight, unicellular, fusiform conidia appeared on nutrient media. In a short time, numerous small dark globose setose microsclerotia emerged in the colony starting from its centre and distributing proportionally throughout agar plates. Two PCR primer sets were used to sequences of the ribosomal internal transcribed spacer (ITS1 and ITS2 regions. Single products of ~450 bp and ~350 bp were amplified by the genus-specific (Cc1F1/Cc2R1 and the species-specific primers (Cc1NF1/Cc2NR1, respectively. Morphological, cultural and molecular characterization of the isolates from roots and fruits showed that root rot and fruit anthracnose of pepper were caused by one and the same causal agent determined as C. coccodes. The isolates from roots showed rapid mycelial growth, gave rise to numerous minute microsclerotia and produced conidia only on SSPA. SSPA supported significantly more mycelium growth and sporulation than all other media tested and could be recommended for production of large quantity of conidia. No pattern of genetic variation associated with the organ or geographic origin

    2015-07-01

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

    Iran is considering Bulgaria's offer to sell it the Russian-made reactor equipment produced for the abandoned Belene nuclear project. The Belene project was initially planned and started in the 1980s, but was stopped in the early 1990s. In 2008 the project was formally given new life, but suspended again in 2010 and abandoned in 2012. The International Court of Arbitration (ICA) ordered the Bulgarian operator Natsionalna Elektricheska Kompania EAD to pay Euro 620 m in compensation to Russia's Atomstroyexport.

    2016-07-01

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

    2004-01-01

    Large-scale surveys rate Bulgaria and the whole of South-East Europe as societies poor in both formal and informal social capital. At the same time studies show that families in the region remain closely knit and norms of reciprocity, empathy and support among members of extended families are valued highly. To throw light upon this contradiction the paper presents results from a qualitative research into family support for youth transitions from school to work in Bulgaria conducted in 2002-20...

    2016-12-01

    Full Text Available The lesser kestrel (Falco naumanni was considered extinct as a breeding species in Bulgaria, but recently a small breeding colony was found again in the south-eastern part of the country. Seven recent observations of flocks or solitary birds of the species in Bulgaria during the post-breeding period are presented and commented here. It is shown that the territory of the country is a regular area for post-breeding dispersal and pre-migratory feeding of lesser kestrels. The origin of these is not known, but most probably birds from the populations of the European part of Turkey, Greece, Republic of Macedonia and Albania are involved.

    2015-10-01

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

    2015-12-01

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

    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.

    2014-03-01

    Full Text Available V.F. Gening’s contribution to the study of the Volga Bulgaria and his views concerning the history and archaeology of this state formation are considered in the article. His sphere of interest first of all included the links between the Volga Bulgaria population and the tribes belonging to preceding cultures, such as Pyanoborye and Imenkovo ones. V.F. Gening investigated the Bolshie Tarkhany, Turaevo and Rozdestveno burial grounds dated by the 8-9th, 5th and 6-7th centuries A.D., and the materials collected modified the notion of the time and character of the Bulgars arrival in the Volga area. He reconsidered the chronology and interpretation of the archaeological monuments, which referred to the epoch preceding the Bulgars appearance on the Volga, and proposed a hypothesis of the Volga Bulgars as a Turkic-Ugrian ethnos. V.F. Gening created a periodization of the Bolgars history in Eastern Europe within the time span between 1st-3rd centuries AD and the early 13th century AD

  18. A Politics of Space and the Historical Transformation of Individuals: A Case Study of Bulgaria

    Directory of Open Access Journals (Sweden)

    N. Nikolov

    2014-06-01

    Full Text Available This study focuses on non-discursive practices connected to the transformation of individuals in the context of Bulgaria. It constitutes an attempt at presenting a decentred history of the present through the vantage point of the architecture of the panel block. Under totalitarianism, the panel block constitutes an institutionalization of a specific politics of space in Bulgaria through which it is shown that the ‘socialist citizen’ becomes an entity that can be constructed or made. During the last years of the regime and after the transition to democracy, the functioning of power relations within the pan-el block are significantly altered, yet not completely erased. The revolution of 1989 is a symbiosis between a certain discontinuity with the past and a contradiction of the old forms of subjectivities, and on the other, a silent continuity of the everyday lives of individuals. Today, the panel structures remain, in the peripheries of the cities, still reminiscent of a time passed, yet visually signifying a new representation, a façade of the contemporary Bulgarian reality. The panel block is a ‘microcosm’ of the Bulgarian society.

    Full Text Available The stroke is a socially significant disease that is characterized with high levels of morbidity and mortality, causing severe disability worldwide. It is the second most significant cause of death among the people in the western world, falling back only to the heart diseases and preceding the cancer, as it causes 10% of the mortal cases in the world. Since 2009 the Bulgarian association of neurosonology and cerebral hemodynamics(BANCH organizes different initiatives of training doctors to conduct a thrombolytic treatment to acute ischemic stroke(AIS. The intravenous thrombolysis has not been established as a leading differential treatment of AIS in Bulgaria, and the thrombolytic therapy is still not well developed in Bulgaria.The suport of national and local institutions is crucial for insuring and guarantee for a proper stroke treatment. Efforts are necessary for adequate financing of the health facilities, as well as professional preparation of the human resource, and training the population via creating an integrated national strategy for its application and control, which can underlie as a state politics in healthcare at optimal usage of public-private partnership.

  20. STATE AND EFFICIENCY OF MANAGEMENT OF AGROECOSYSTEM SERVICES – THE CASE OF BULGARIA

    2010-01-01

    Full Text Available This paper incorporates New Institutional Economics and analyzes the state and efficiency of management of agro-ecosystem services in Bulgaria. Firstly, it presents framework of analyses of management of agro-ecosystem services including: definition of agroecosystem services and its management; specification of management needs and spectrum of governing modes (institutions, market, private, public, hybrid; assessment of efficiency of different form of management in terms of potential to protect eco-rights and investments, assure socially desirable level of agro-ecosystem services, minimize costs, coordinate and stimulate eco-activities, meet preferences and reconcile conflicts of related agents. Secondly, it identifies and assesses the management of agro-ecosystem services in Bulgaria. Transition and EU integration have brought about significant changes in the state and management of agroecosystems services in the country. Newly evolved market, private and public governance have led to a significant improvement of a part of agro-ecosystems services introducing modern ecostandards and public support, enhancing environmental stewardship, disintensifyingproduction, recovering landscape and traditional productions, diversifying quality, products,and services. At the same time, the novel eco-management is associated with new challenges such as unsustainable exploitation, lost biodiversity, land degradation, water and air contamination. Moreover, implementation of EU common policies would have no desired impact on agro-ecosystem services unless special measures are taken to improve management of public programs, and extend public support to dominating small-scale and subsistence farms.

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

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

    Full Text Available The objective of this paper is to select some relevant macroeconomic determinants for foreign direct investment (FDI in Bulgaria and Romania since the start of the recent economic crisis (2008-2015. Even if the economic recession installed in 2009 in Romania, the foreign investors’ decisions were influenced by the moment of global recession from 2008. A Bayesian approach was proposed, because of the small sample for the variables in analyzed period: FDI as percent of GDP, real GDP rate, unemployment rate, inflation rate, real interest rate, real effective exchange rate index (2010=100 and money demand (M2 as percent of GDP. The estimation results reflected that foreign investors in both countries were attracted by the increase in GDP from a year to another. On the other hand, for Bulgaria the inflation rate was the strongest determinant, indicating the economic stability of the country that made huge efforts in getting one digit inflation rate. In Romania, as expected, the foreign investors were searching for cheap labour force and the increase in unemployment rate attracted more FDI during the crisis period.

    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.

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

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

    Full Text Available Bulgaria's membership in the European Union defines the orientation of our country in line with the key strategic priorities of Europe 2020, which aims to achieve smart, sustainable and inclusive growth. The role of the cooperative system becomes especially important at this time when the EU itself is constructed as a union of equal socially oriented states. In the paper is depicted the role of the labour working producer cooperatives for disabled people as one of the main actors of the social economy in the EU which contribute to solving many economic and social problems of a substantial part of the Bulgarian population and to implement the priorities of the strategy "Europe 2020". In line with this aim, are given suggestion for the trends in improving their activity. So that they could provide better labour rehabilitation, strengthen the social integration of their members, promotion of production, improvement of working conditions, proposals for changes in legislation.

    We report the first detailed accounts of bites by the Balkan adder, Vipera berus bosniensis from Bulgaria. Documentation of bites by this subspecies is very rare in the literature and most available accounts are from the northern limit of its distribution. V. berus bosniensis is considered to possess neurotoxic venom but little evidence has hitherto been available to support this supposition. In this case series symptoms typical of adder bites developed including oedema, nausea, dizziness, lymphangitis, vomiting, and diarrhoea together with aberrant symptoms such as diplopia and ptosis that confirm the presence of neurotoxic venom in Balkan adders. In addition, unusual and atypical symptoms of adder bites such as painless bites and muscle cramps appeared. The inadequate treatment in hospital and the remote habitats in which this species is encountered are potential sources of complication.

    Full Text Available Multi-level governance is widely used throughout the world, especially in more economically developed countries. In part, this is due to the presumed benefits of decentralization in terms of public-service delivery, and in part, it is due to a desire to disperse political power and governmental authority. Thus, 25 years ago, when major governmental reform initiatives were begun in many countries around the world, especially in Central and Eastern Europe and Latin America, much attention was devoted to establishing and / or strengthening local governments. This was the case in Bulgaria and Paraguay, two countries from different parts of the world, but similar in size, economic development and a history of highly centralized and authoritarian regimes. The purpose of this paper is to examine and better understand the processes of decentralization as they took place in those two countries and those factors which facilitated and / or hindered efforts to initiate effective local government.

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

    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.

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

  3. Does management improve the state of chestnut (Castanea sativa L. on Belasitsa Mountain, southwest Bulgaria?

    Directory of Open Access Journals (Sweden)

    Zlatanov T

    2015-12-01

    Full Text Available Chestnut forests in the Belasitsa Mountain region of southwest Bulgaria were traditionally intensively managed as orchard-like stands for nut production. More recently, management intensity has been sharply reduced as a result of rural abandonment, which combined with the effects of chestnut blight has led to marked structural changes in these forests. The focus of this paper is on the seed-based regeneration potential and seedling survival of chestnut in mixed stands managed over the past 15 years. Results suggest that management of stands under a high-forest system is appropriate, and regeneration from seed has advantages over coppicing if competing species can be controlled. An investigation into “sanitation cutting” performed since the 1990s shows that this had not a successful response to blight infestations.

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

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

    Directory of Open Access Journals (Sweden)

    Christoph Bühler

    2008-06-01

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

    Full Text Available A study on the trophic spectrum of three species of lacertid lizards (Lacerta agilis, Lacerta trilineata and Podarcis muralis was carried out, based on 20 specimens collected in the period 1967-1973 in various localities in Bulgaria. The analyzed data showed that the insects (Insecta are the most numerous and the most frequently met among the alimentary components of the total amount of food of the studied stomachs (except for Lacerta agilis, where spiders are slightly predominating. The non-insect components consisted spiders and isopods. The largest niche breadth was recorded in Lacerta trilineata (8.25, followed by Podarcis muralis (5.20 and Lacerta agilis (3.44. The niche overlap between the three species (pair-wise comparison showed medium values and in our opinion there should not be any serious competition for food resources at the places withsympatric distribution.

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

    Full Text Available Five fired clay structures from the Northeast sector of the Early Neolithic settlement of Yabalkovo in the Maritsa valley, Bulgaria were a subject of an archaeomagnetic investigation. The results of the detailed rock-magnetic experiments carried out show that the collected materials are suitable for archaeomagnetic study and reliable determinations for past geomagnetic field elements can be obtained. According to the mean values calculated for the ancient geomagnetic field direction and intensity, two different periods of time can be undoubtedly distinguished for the investigated structures. This coincides exactly with the two chronological horizons suggested by the excavators. The archaeological observations point that the oven in sq. K36, the hearth in sq. F16 and the hearth in sq. H31 are related to Horizon II, while the hearths in sq. I31 and sq. F18 are connected with Horizon I. Based on the Bulgarian reference curves (latest version, the following archaeomagnetic dating intervals are received: Yabalkovo – Horizon II – (5685–5489 BC and Yabalkovo – Horizon I – (5472–5427 BC. These results agree well with the archaeological data that structures from Horizon II are older than structures from Horizon I. The existing 14C dates (for materials taken mainly from the Southwest sector of the settlement show considerably older dating intervals but they are not able to differentiate chronologically the different structures. The obtained archaeomagnetic determinations for Yabalkovo are compared with these available for other archaeomagnetically studied Early Neolithic sites from Bulgaria and Northern Greece. This comparison indicates that Horizon II of Yabalkovo can be synchronised with the younger layers of Kovatchevo (Karanovo I, Stara Zagora (Karanovo II and Dobriniste. Horizon I of Yabalkovo is chronologically comparable with Horizons VII+VIII of Samovodene and Avgi (Nortern Greece.

    Harizanova Stanislava N.

    2016-12-01

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

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

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

    2014-03-01

    Full Text Available A special type of jewelry, earrings shaped as question mark from Bulgaria, is considered. Their spreading area and possible sources of their emergence in the culture of 13-14th-century Danube Bulgaria are made clear. Two stylistic groups are distinguished: those with a simple stylized pattern and those with an intricate pattern. The second group, a more numerous one, finds an analogy in the territory of the Golden Horde. According to the author, it can be argued that the emergence and spread of this type of earrings in the Bulgarian environment is the result of the influence of a "supraethnic" culture of the steppe peoples. These peoples (mainly the Cumans were in the orbit of the Golden Horde.

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

    2013-05-01

    Full Text Available The height-diameter relationship is an important and extensivelyinvestigated forest model, but generalized and mixed-effects models of wider applicability are currently lacking in the forest modeling literature for Scots pine (Pinus sylvestris L. plantations in Bulgaria. Considering the practical advantages of deterministic and mixed-effects models, the present study aims to derive a generalized deterministic height-diameter relationship and a simple mixed-effects model for plantation-grown Scots pine in Bulgaria. Ten generalized and six local models of adequate mathematical properties were selected and examined in several subsequent steps with a representative data set.A deterministic model was derived for tree height reconstruction fromthe individual tree diameters, stand dominant height and diameter,number of trees per hectare and stand age. Mixed-effects models weredeveloped from the individual-tree and stand diameters and heights applicable to determine the height-diameter relationship in field surveys. Both types of models can be applied with confidence, according to their advantages and specifications, for estimating the height-diameter relationship of Scots pine plantations in Bulgaria, presenting a unique contribution for the particular species, study area and type of model. The choice of the tested models is relevant to the height-diameter relationship investigation of biologically related and geographically close species and types of stands and the study procedure allows repetition of the work to provide reliable solutions of the problem where information on such type of model is deficient or incomplete.

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. By the means of the systematized database of meteorological and agrometeorological data which we have at disposition for the period of this survey (1971-2000); Provide assignment of the expected climatic changes according to the scenarios in the centers for observing and investigations of climatic changes in Europe, US., Canada and Australia (ECHAM 4, HadCM 2, CGCM 1, CSIRO-MK2 Bs and

    A detailed field and laboratory study on small 0.84-ha test site of agricultural land near Sofia (Bulgaria) has been carried out in order to test the applicability of magnetic methods in soil erosion estimation in the particular case of strongly magnetic parent material. Field measurements of magnetic susceptibility were carried out with grid size of 6 m, resulting in 258 data points. Bulk soil material was gathered from 78 grid points. Natural, non-disturbed soil section was sampled near the agricultural field for reference profile of complete undisturbed soil. Surface susceptibility measurements reveal well-defined maxima down slope which, however, cannot be assigned directly to a certain depth interval, corresponding with susceptibilities along the non-disturbed soil profile. This is caused by the high magnetic susceptibility of the lithogenic coarse-grained magnetic fraction. Non-uniqueness is resolved by using magnetic susceptibility of coarse (1 mm > d > 63 μm) and fine (d soil profile, which corresponds to a certain part of the studied area. After the application of an empirical model to predict the values of magnetic parameter after tillage homogenization and removal of soil material from the surface, the amount of soil loss is estimated.

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

    Full Text Available The research paper is a comparative analysis of the budget revenue in Bulgaria, Croatia, Czech Republic, Poland and Romania, taking into account the main features in light of the contribution of indirect and direct taxes and social contributions to the achievement of public revenues. Theme presents a topic of great interest, both theoretically and practically, given possible solution to increase public budget revenue in these countries, most of them being new member stated of European Union and who wants to catch up all the lost period within socialism time. As a common conclusion it can be seen that all countries need to improve their judicial system and combating crime and tax evasion. It is necessary to increase the independence of the judiciary, reducing bribery, reducing undeclared work and the establishment of independent anti-corruption institutions. Also the analyzed countries must improve public expenditure system, reducing bureaucracy and pay attention on profitable investments in order to increase budget revenues and encourage employment and unemployed university graduates, this is possible also by improving the mechanism of attraction and use of EU funds for investment within public and private sector.

    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.

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

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

    Full Text Available An overview of the activities overtaken during risk of flooding situations, in one of the more often flooding region - the watershed of Varbitsa river (Southeastern part of Bulgaria - has been performed. The main cognitive parameters for risk perception and risk definition, depending on regional, social and historical factors have been examined. The existing information and instructions for mass media communication in relation to the process of interaction in a disaster situation have been discussed. In connection to determination of the risky segments in the basin and plans for announcement, the prevention communication measures have been outlined. On the basis of the Bulgarian normative legislation, the activities concerning organization of communications in a risk-of-disaster situation and mutual aid between authorities, which are part of the Integrated Help System have been indicated. It has been accented on the necessity of a more effective realization of the action plans during natural disasters and especially flooding, in order to improve the partnership between authorities and participants in the communication process during risk-of-flooding situations.

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

    2014-12-01

    A detailed field and petrographic study constrains the volcanic evolution and environment setting of the volcano-sedimentary-hosted Chelopech Cu-Au epithermal deposit, Bulgaria. Magmatic activity and associated high-sulfidation epithermal mineralization occurred at about 91 Ma in the Panagyurishte ore district of the Eastern European Banat-Timok-Srednogorie metallogenic belt. Volcanic and hydrothermal activity took place in a complex subaqueous setting, resulting in the intercalation of quartz sandstone with andesitic volcanic and volcaniclastic breccia. There are also hypabyssal andesite intrusion, phreatomagmatic breccia and interbeds of pyroclastic, oolithic and bioclastic rocks. The presence of altered cerebroid ooid-bearing sedimentary units characteristic of salty environment is in accordance with a lagoon environment predating the mineralization at Chelopech. Four principal stages of evolution for the Chelopech district are proposed based on field and petrographic observations. Initial volcanism occurred in a lake or in a coastal, shallow lagoon environment above crystalline basement. The Chelopech "phreatomagmatic" breccia and subsurface andesites were emplaced at this time. Subsequent hydrothermal activity produced the different hydrothermal breccia types, advanced argillic and quartz-phyllic alteration, and Au-Cu vein and replacement mineralization. The end of volcanism and hydrothermal activity was associated with opening of a pull-apart basin that covered the Chelopech environment with a sedimentary flysch. Tertiary compression faulting juxtaposed various rocks and tilted the ore deposit during the Alpine orogeny.

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

    Full Text Available Introduction: Increasing numbers of persons are living with multiple chronic diseases and unmet medical needs in Bulgaria. The Bulgarian ‘Diabetic care’ non-profit (DCNPO programme aims to provide comprehensive integrated care focusing on people with diabetes and their co-morbidities. Methods: The DCNPO programme was selected as one of eight ‘high potential’ programmes in the Innovating Care for People with Multiple Chronic Conditions (ICARE4EU project, covering 31 European countries. Data was first gathered with a questionnaire after which semi-structured interviews with project staff and participants were conducted during a site visit. Results: The programme trains diabetic patients to act as carers, case managers, self-management trainers and health system navigators for diabetic patients and their family. The programme improved care coordination and patient-centered care by offering free care delivered by a multidisciplinary team. It facilitates the collaboration between patients, volunteers, health providers and the community. Internal evaluations demonstrate reduced hospital admissions and avoidable amputations, with consequent cost savings for the health care system. Conclusion: Integrated care provided by volunteering patients can empower people suffering from diabetes and their co-morbidities and address health and social inequalities in resource-poor settings. It can also contribute to an increased trust and improved satisfaction among vulnerable patients with complex care needs.

    2004-07-01

    A great variety of corrosion processes are observed on the territory of the Oil Refinery LUKoil-Neftochim Burgas AD, Bulgaria. They are a result of aggressive action of wide range of chemical active reagents and environments, industrial atmosphere with sea climate influence and underground water with varied composition. Substantial corrosion monitoring is used in oil distillation plant, petrochemical and other refinery units. A part of the most important cases of successfully solved corrosion problems are included in this paper - corrosion in Ethyl-benzene unit alcilators, corrosion protection of equipment and floors in concentrated sulfuric acid in the Sulfuric Acid Alkylation plant, corrosion protection of electro-filters in the Chemical Cleaning of Service Water System, chemical resistant floor in PAN and AN plant, outside varnish protection of tanks, vessels, pumps, steelworks etc. There are many proper solutions suggested, including wide range of coatings and new resistant materials offered by well-known companies - Hempel, Chesterton, Permatex DuPont, Paint International and many others which work in close collaboration with our laboratory. Those problems are typical of all oil refineries and petrochemical plants and are possible to be applied successfully. (authors)

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

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

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

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

    2013-10-01

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

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

    Full Text Available Royal jelly (RJ is popular among consumers around the world due to its perceived health benefits. The purpose of this study was to assess the levels of free and total amino acid profile as well as protein content in order to characterize Bulgarian RJ samples. A total of 17 fresh and commercial RJ samples from different regions of Bulgaria were analyzed. The results obtained show that proline (Pro, lysine (Lys, methionine (Met, aspartic acid (Asp, cysteine (Cys, histidine (His were major free amino acids (FAAs in RJ. The average content of Pro was 2.3 mg/g. The FAA content ranged from 5.5 to 6.2 mg/g of RJ. The most abundant total amino acids (TAAs were aspartic acid (Asp, glutamic acid (Glu, lysine (Lys, leucine (Leu, serine (Ser and proline (Pro. The average TAA content in fresh and commercial RJ were 129±10 and 114±8 mg/g, respectively. The results obtained for TAA content were used to establish a range for amino acid composition of Bulgarian RJ. The content of proteins was higher in fresh RJ than in commercial samples and this difference was significant (p<0.05. The following ranges were observed for fresh and commercial samples 14.7–17.3 and 12.5–14.9 mg/g, respectively. DOI: http://dx.doi.org/10.4314/bcse.v29i3.16

    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 × 106 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. PMID:26019571

    Almost one million new cases of gastric cancer were estimated to have occurred in 2012, making it the fifth most common malignancy in the world. It is also the third leading cause of cancer death of people of both genders worldwide. The aim of this study is to evaluate the significance of some prognostic factors for gastric cancer survival in 155 patients treated at Aleksandrovska University Hospital, Sofia, Bulgaria. This retrospective study includes patients diagnosed and treated at Department of Surgery of Aleksandrovska University Hospital for the 9-years period of time between January 2005 and December 2013. We classified the prognostic factors as patient-related (age at diagnosis specification, gender, and blood type), tumor-related (N-stage, tumor differentiation, process localization), and treatment related (patients who had radical surgery and adjuvant therapy). We found that blood type is the only statistically significant prognostic factor for overall survival from the patients-related group of factors (p = 0.030). The only prognostic factor from the ones in the tumor related group remains the N-stage according to the TNM classification (p = 0.003). Adjuvant could not prove its value for overall survival (p = 0.675).

    Institutional capacity is increasingly considered as a key factor in implementing current climate actions in different parts of the world as well as in preparing for future actions in the medium term. The companion paper to this document, 'Institutional Capacity and Climate Actions' attempts to provide a general assessment of the institutional challenges to climate mitigation (and, to a lesser extent, adaptation). However, institutional capacity assessments are essentially country-specific. The case studies included in this document present initial capacity assessments for three different countries, namely Mexico, India and Bulgaria. These country-specific capacity assessments provide useful insights on each country's institutional challenges and how they might affect the development of current and future actions. These three case studies also represent different ways to analyse the links between institutional capacity and climate actions. The Mexican case study analyses the recent evolution in the development of capacity for climate change mitigation in Mexico. First, capacity is analyzed in terms of seven clusters of functions, each one with different levels of performance. The document also provides a background of national circumstances that frame the capacity building process in the case of Mexico. A description follows of the recent evolution of the performance of each one of the seven identified functional clusters in Mexico. Both progress and regressions are shown. One of the salient features is the recently acquired capacity to develop in an autonomous way regular inventories of greenhouse gases, particularly in the energy-related sectors. The document also identifies some institutional or political bottlenecks or obstacles that should be overcome if the country is to proceed at a faster pace toward the adoption of quantifiable targets. Finally, the Mexican case study presents some ideas on the relationships between changes in the

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

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

    Full Text Available A malocclusion is a misalignment of teeth or incorrect relation between the teeth of the two dental arches. The aim of this presentation is to show the percentage of the children with malocclusions and comparison between children with mild and severe malocclusions from rural and urban regions Materials and methods: 1200 children between 5 and 6 years old from North-eastern Bulgaria (600 urban and 600 rural were examined. WHO standards were applied and the data was collected in WHO statistic forms, which were modified accordingly. The children were divided in 3 groups-healthy, with mild and with severe malocclusions according to Angles classification. Results: More than a half of the urban children are healthy – 51,5% and the biggest percentage of the malocclusions are mild – 31,3%, only 17,2% have severe malocclusions. The rural children are without malocclusions – 23,8% and – 39,2% of them are with severe orthodontic deformations. Relative shares of children with malocclusions from the urban – 48,5% and rural regions – 76,2% The relative share of the healthy children from both urban and rural regions is 37,7%. The relative share of the children with malocclusions from urban and rural regions is 62,3%. Conclusion: A little percent of the rural children are without malocclusions and more of them are with severe ones. We suggest that specialist have to work on better prevention in these regions.

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

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

    Radioactive waste (RAW) management in NPP is a complex problem, that can be considered as a combination of sub problems, for example scientific, administrative, social, economical, etc. The separate examination of these sub problems does not lead to creation of overall system for optimal RAW management. There`s no doubt that such an administrative system, supported by information technologies, should present in every one existing and planned nuclear power plant to optimize its operation as a whole, not only separate elements. The aim is to avoid the fallacy of the single and the complex. This paper presents a basic part of the whole information management system as defined above that concerns RAW management. The information management system is prepared for NPP-Kozloduy, Bulgaria by means of modern concepts and technological schemes and is aimed to help the administrative personnel in this very important activity - RAW management. On the base of objective data about the available waste and prognoses about arisings in the future, on the base of chosen technologies and equipment the system gives multi-variant plan for treatment, processing and disposal of waste, after the choice of a variant it monitors its application in the practice.

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

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

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

    Full Text Available Type 2 diabetes mellitus (T2DM is a growing public health problem in Bulgaria. While individual and lifestyle determinants have been researched; till date there has been no study on environmental risks such as road traffic, noise, and air pollution. As a first step toward designing a large-scale population-based survey, we aimed at exploring the overall associations of prevalent T2DM with exposures to road traffic, noise, and air pollution. A total of 513 residents of Plovdiv city, Bulgaria were recruited. Individual data on self-reported doctor-diagnosed T2DM and confounding factors were linked to objective and self-rated exposure indicators. Logistic and log-link Poisson regressions were conducted. In the fully adjusted logistic models, T2DM was positively associated with exposures to L den 71-80 dB (odds ratio (OR = 4.49, 95% confidence interval (CI: 1.38, 14.68, fine particulate matter (PM 2.5 25.0-66.8 μg/m 3 (OR = 1.32, 95% CI: 0.28, 6.24, benzo alpha pyrene 6.0-14.02 ng/m 3 (OR = 1.76, 95% CI: 0.52, 5.98 and high road traffic (OR = 1.40, 95% CI: 0.48, 4.07.

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.

    2008-01-01

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

    2013-07-01

    Full Text Available The height-diameter relationship is an important and extensively investigated forest model, but generalized and mixed-effects models of wider applicability are currently lacking in the forest modeling literature for Scots pine (Pinus sylvestris L. plantations in Bulgaria. Considering the practical advantages of deterministic and mixed-effects models, the present study aims to derive a generalized deterministic height-diameter relationship and a simple mixed-effects model for plantation-grown Scots pine in Bulgaria. Ten generalized and six local models of adequate mathematical properties were selected and examined in several subsequent steps with a representative data set. A deterministic model was derived for tree height reconstruction from the individual tree diameters, stand dominant height and diameter, number of trees per hectare and stand age. Mixed-effects models were developed from the individual-tree and stand diameters and heights applicable to determine the height-diameter relationship in field surveys. Both types of models can be applied with confidence, according to their advantages and specifications, for estimating the height-diameter relationship of Scots pine plantations in Bulgaria, presenting a unique contribution for the particular species, study area and type of model. The choice of the tested models is relevant to the height-diameter relationship investigation of biologically related and geographically close species and types of stands and the study procedure allows repetition of the work to provide reliable solutions of the problem where information on such type of model is deficient or incomplete.

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

On European Union level, standards have been set down in Regulation (EC No. 1901/2006 of the European Parliament and of the Council of 12 December 2006 on medicinal products for paediatric use. The licensing regime that has been introduced on a national level requires the performance of documentation evaluation that addresses a major change in a clinical trial and non-interventional research. Legal definitions of the terms "principal investigator" and "coordinating investigator" have been introduced. The "principal investigator" is the medical doctor or the dentist, designated by the sponsor, who leads the overall execution of the clinical trial in accordance with the approved protocol and good clinical practice guidelines and is responsible for the researchers. The "coordinating researcher" is a researcher appointed to coordinate researchers from different centres participating in a multicentre trial. Ethic committees performing review have to provide independent advice on the extent to which a biomedical research proposal complies with recognized ethical standards. Scientific research must necessarily conform to commonly accepted scientific principles and be based on thorough knowledge of scientific literature and other relevant sources of information.

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

    Full Text Available There is only limited data on the prevalence of epidermal growth factor receptor (EGFR activating mutations in squamous cell carcinomas and adenosquamous carcinomas of the lung in patients of the Southern Bulgarian region and the efficacy of EGFR tyrosine kinase inhibitors. AIM: Previous reports for Bulgarian population showed high incidence of EGFR mutations in the squamous cell carcinomas, so we set the goal to investigate their frequency in Southern Bulgaria, after precise immunohistochemical verification of lung cancers. MATERIALS AND METHODS: Two hundred and thirty-six lung carcinomas were included in this prospective study. All biopsies were initially analysed with p63, TTF1, Napsin A, CK7, CK34βE12, synaptophysin, CK20 and CDX2. Two hundred and twenty-five non-small cell lung carcinomas were studied with real-time PCR technology to assess the status of the EGFR gene. RESULTS: We detected 132 adenocarcinomas (58.7%, 89 squamous cell carcinomas (39.2%, 4 adenosquamous carcinomas (1.8%, 9 large cell neuroendocrine carcinomas (3.8% and 2 metastatic colorectal adenocarcinomas (0.8%. Activating mutations in the EGF receptor had 3 out of 89 squamous cell carcinomas (3.37%. We have established mutations in L858R, deletion in exon 19 and rare mutation in S7681. One out of four adenosquamous carcinomas had a point mutation in the L858R (25%. CONCLUSIONS: The frequency of EGFR mutations we found in lung squamous cell carcinomas in a Southern Bulgarian region is lower than that in European countries. Ethnic diversity in the region does not play role of an independent predictive factor in terms of mutation frequency.

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

    Dermatosurgery and dermatooncology are an integral part of dermatology as a speciality, and this postulate is strictly respected in a high percentage of European dermatological units. Due to the fact that a number of other specialties interweave with the subject of therapy - the surgical treatment of the patient with skin tumors, the positioning of dermatosurgery as part of dermatology is generally controversial (according to some), and at the same time is often the subject of a number of debates and conflicts. These include maxillofacial surgeons, plastic surgeons, regenerative and reconstructive surgeons, surgical and medical oncologist, etc. The advantages of these specialities are mainly based on good medical practice and good surgical techniques that are applied. In contrast, their disadvantages are based on the lack of good awareness of the initial surgical approach as well as the need for time-adjusted and accurately performed additional surgical interventions which should befurthermore careful scheduled with the relevant oncology units. Losing this thread, in practice, it turns out that we are losing the patients themselves or, looking laconically, we are working with reduced efficiency and effectiveness. Although for the last 15 years the positions of these sub-sectors in Bulgaria had been underdeveloped, a certain ascent has been observed nowadays or from a couple of years ago. This advance is undoubtedly due to the influence of the German Dermatological School, presented by Prof. Dr. Uwe Wollina, Head of Department of Dermatology, Venereology and Allergology in Dresden, Germany, as well as due to other respected representative of the Italian Dermatological School - in the face of Prof. Dr. Torello Lotti, Head of the Dermatology Unit at G Marconi University of Rome, Italy.

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

    Full Text Available Larvae of Chironomus riparius Mg. (Chironomidae, Diptera collected from two polluted water basins in Bulgaria, the Maritsa and Chaya Rivers (adjacent to Plovdiv and Asenovgrad respectively, a small pool (near Plovdiv plus controls reared in the laboratory were studied. High concentrations of the heavy metals Pb, Cu and Cd were recorded in the sediments of the polluted stations. Marked somatic structural chromosome aberrations were found in C. riparius salivary polytene chromosomes from the field stations and their frequency was significantly higher (p<0.01 compared to the control. The observed somatic chromosome changes are discussed as a response of the chironomid genome to aquatic pollution. A new cytogenetic index based on the number of aberrations found in larvae from polluted regions in comparison with the control was applied to the data to more easily evaluate the degree of heavy metal pollution in aquatic ecosystems. Our study of a polluted site near the River Chaya showed that the somatic index was very high at 3.35 for 2010 and 11.66 for 2013 compared to 0.5 in the control. The cytogenetic index was effective in showing that all studied sites were highly polluted in comparison with the control. To determine the mechanism involved in the concentration of aberration breakpoints within specific regions of the chironomid polytene chromosome the FISH method was applied. The localization of a transposable element TFB1 along the polytene chromosomes of C. riparius was analyzed and the sites of localization were compared with breakpoints of chromosome aberrations. A significant correlation (p<0.05 was found which shows that most of the aberrations do not appear randomly but are concentrated in sites rich in transposable elements.

    2016-10-01

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

    2006-01-01

    Full Text Available Different genetic types (endogene and supergene of barite from the Kremikovtsi deposit (Bulgaria were studied by Laser-induced time-resolved luminescence (LITRL, Infrared (IR and Raman spectroscopy. The IR spectra of the endogene barites are quite similar to those reported in the literature and do not show appreciable differences among them. The IR spectra of the supergene barites are almost identical to those of the endogene ones in respect to the positions of the vibrational modes ν1, ν2 and ν4 of SO4 2 except for a shift of 3 cm-1 for the ν 3 band. They displayed a presence of additional bands, which are close to the ν3 and ν1 modes of CO3 2- in calcite. The Raman studies support the suggestion that the supergene barite contains traces of calcite. The modern LITRL technique allowed the detection of several luminescent centers in the endogene barite. Eu3+ luminescence was identified for the first time in barite. The different emission spectra at 266 and 532 nm excitations suggest there are at least 2 structural positions for Eu3+ in the barite crystal lattice. The luminescent spectra also revealed a rather unusual violet-blue Nd3+ emission, which usually occurs in the IR spectral range, as well as emissions of Ce3+, Eu2+, Tb3+, Ag+, Sn2+(? and UO2 2+. The oxidation state of cations isomorphically present in the barite crystal lattice suggests the endogene barite in the Kremikovtsi deposit precipitated from reduced fluids supposedly subjected to cooling (conductive/convective and oxidation (mixing with seawater.

    Full Text Available The authors examine the logistic ecology of 30 large-scale networks that were active in human smuggling and trafficking from Albania and Bulgaria to Belgium (1995–2003. Ten networks were studied in greater detail in order to determine three final profiles of networks, based on their use of structural and operational intermediary structures. They are called the “individual infiltration” and the “structural infiltration” human smuggling patterns, and the “violent-control prostitution” trafficking pattern. It should be noted that the business is organized in such a way that the organizers of the logistical support are never inculpated.

    Measurements of the constant electric field vector in the region of the midlatitude ionospheric trough have been obtained using the IESP-IPMP electromagnetic instrument complex on board the Intercosmos-Bulgaria 1300 satellite. Electromagnetic field data for the nighttime four-hour period of quiet geomagnetic conditions are analyzed, and the results are discussed. It is shown that the midlatitude plasma-density trough is due less to local electric field conditions than to plasma temperature variations and charged particle flows in other parts of the ionosphere.

    Numerous differences in the petrography and organic geochemistry of two Tertiary, low rank coal deposits of Bulgaria, formed within comparable depositional environments, are outlined. Different floral assemblages are indicated as the main sources of organic matter. For the Eocene Bourgas sub-bituminous coals a warm climate plant community dominated by angiosperms is reflected in the biomarker composition, whereas a coniferous flora was the main source of the resinous organic matter of the Miocene Maritza-East lignite. The results are in agreement with palaeobotanical data. These differences in the peat forming vegetation of the Paleogene compared to the Neogene of Bulgaria are attributed to decreasing temperature during the Tertiary.

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

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

    In the period 2013-2016 the National Centre of Radiobiology and Radiation Protection (NCRRP) at the Ministry of Health of Bulgaria has developed a web based platform for performing national patient dose surveys and establishing Diagnostic Reference Levels (DRLs). It is accessible via internet browser, allowing the users to submit data remotely. Electronic questionnaires, specific for radiography, fluoroscopy, image guided interventional procedures, mammography and CT, were provided. Short and clear manuals were added to guide users and minimise human errors. The web-based data collection platform is functional and is currently being used for performing the third national dose survey in Bulgaria, launched in 2016. Data analysis is facilitated due to the standardisation of collected data and their storing. Using the platform, the participating facilities can establish their typical dose levels based on the median value, and compare them to DRLs. A disadvantage of the platform is the need to enter data manually, but it is opened for future upgrades for automatic data harvesting and analysis. Various practical approaches were used to overcome the lack of qualified human resources and insufficient understanding of the DRL and dose tracking concept and to motivate facilities to submit data.

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

    Full Text Available Pollution of Shokarski stormwater canal and its influence on the quality of the Varna Black Sea coastal area, Bulgaria. In the present study was investigated the pollution of Shokаrski stormwater canal, discharging its water into the Varna Black Sea coastal area. Monitoring was carried out during 2011 year at 5 sites along the canal water flow. The pollution was determined by organoleptic and physico- chemical characteristics, nutrients concentrations and the organic load. Critical levels of dissolved oxygen were measured at some of the monitoring sites ranging from 0,65 to 2,79 mg/dm3. Ammonium and nitrite concentrations were above the threshold limits at all sites. The phosphates’ concentrations varied very dynamically ranging from 0,18 to 11,8 mg/dm3 and in most of the cases exceeded the threshold limit. Very high levels of biochemically degradable organic pollutants were determined with biochemical oxygen demand values reaching- 68,96 mg/dm3. The Shokarski canal pollution could be considered as a tremendous thread for the quality of the Varna Black Sea coastal area, Bulgaria.

    Full Text Available In the context of internationalization and globalization of the world economy, regional competitiveness is thoroughly debated by politicians and policy makers, emphasizing measurable differences between development regions, without any clear political or conceptual framework. The process of European Union integration is a main driving force of change, aiming to increase the efficiency and competitiveness of the fragmented European economy in the face of increasing internationalization. This often exposes countries and regions with unequal resources and technology and different economic structures to international competition. Such is the case of Romania and Bulgaria, countries that after joining the European Union in 2007 were given an opportunity to recover in terms of regional competitiveness and economic growth, namely structural funds as a form of nonrefundable European financial help to disadvantaged regions of member states. This research is thus focused on underlining and analyzing the relation between structural funds’ absorption and the degree of regional competitiveness for the development regions of Romania and Bulgaria, during their first programming period, through identifying and analyzing the factors that influence regional competitiveness and the amount of structural funds absorbed. First, two competitiveness country profiles are created based on data provided by relevant international organisms and second, an impact analysis is developed using six regional competitiveness indicators, grouped into three categories (economic, social and technological. Results show that EU funds critically influence the competitiveness of Romanian and Bulgarian regions, providing reliable data for policy decision makers

If the two parties have different viewpoints of the processes in the supply chain, the fulfillment of the goal to satisfy the end customers may be hindered. The purpose of this article is two-fold: First, to investigate the characteristics of logistics outsourcing in Bulgaria from the perspectives of the logistics service providers and their customers, and more specifically, to compare their viewpoints concerning the motives for outsourcing, the methods and contents of communication and some relationship management aspects; Second, to assess the relations of the communication and relationship management aspects to customer satisfaction. This article is based on empirical data provided by 138 manufacturing and trading companies and 136 LSPs and collected through two structured questionnaires designed to address the researched issues. The data were analyzed using descriptive statistics and the independent samples t-test. The research found that the service related reasons for logistics outsourcing are prevailing and that LSPs overestimate, compared to manufacturing and trading companies, motives related to service, organizational capabilities and relationships, while more manufacturing and trading companies concern as important the availability of logistics assets and the provision of value-added services. The research also found that both the LSPs and their customers consider that the extent of sharing of knowledge and information essential for material flow integration is very low and that the usage of team meetings and joint teams is quite rare. Also, customers do not view their relationships with the LSPs as so collaborative as viewed by the LSPs. Furthermore, the

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

    Full Text Available INTRODUCTION: Eating disorders have been intensively researched over recent decades. However, there has been insufficient research into the early assessments for detecting the risk of developing disordered eating. We report preliminary results from a project aiming to assess the prevalence of eating attitudes and behaviors that heighten the risk of eating disorders. The study examines a non-clinical sample of adolescents and adults from two cities of South Bulgaria.METHODS: In this cross-sectional epidemiological study, a total of 1285 volunteers of 828 females and 453 males, aged 14 to 59 years, were surveyed to assess disordered eating attitudes and behaviors. For this purpose, the study used the ‘SCOFF’ questionnaire, the Eating Disorder Diagnostic Scale (EDDS, and the Eating Attitudes and Behaviors Questionnaire (EABQ, which was developed for this study.RESULTS: The proportion of these volunteers underweight (body mass index below 17.5 was 9.8%. Of the total subject, 34.7% provided two or more positive answers for the SCOFF questionnaire (two being the upper threshold for indicating 100% sensitivity to anorexia and bulimia. The results differed between males and females: 21.6% and 42.1%, respectively, in this regard. A factor analysis (oblimin rotation of EABQ items revealed four main factors: body shape and weight concerns, personal control over eating and calorie intake, dieting, and preoccupation with food and binge eating. A Spearman’s correlation analysis showed moderately significant correlations (p < 0.001 between the total scores of the SCOFF questionnaire, EABQ, and the scores for three groups of items in the EDDS for assessing eating attitudes and behaviors.CONCLUSION: We found a greater ED risk in adolescents compared with the older groups and in females compared with males. One fifth of males studied were at high risk of ED and ages between 19 and 39 years also appeared at risk. The EABQ was validated as a sensitive and

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

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

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

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

    Full Text Available Taking a closer look at the spatial distribution of industrial sectors, it becomes quite obvious that there is an increasing disposition for industries to concentrate in certain regions in order to benefit of agglomeration assets. In this context, we consider necessary to analyze how industrial agglomerations have evolved over time and to what extent major transformations have affected agglomeration phenomenon in lagging regions of Eastern countries, finally our paper bringing supportive evidence from Romania and Bulgaria. To what extent, have patterns of industrial agglomeration modified during the transition period? Has relocation of economic activities taken place? What are the main determinants of industrial concentration patterns? These are some crucial questions that we try to find a realistic response through the present paper. Eastern economies are notably challenging from this point of view because they experienced several decades long economic development period which was earmarked by socialist industrialization. Under the planned economy, these countries have faced more barriers to an efficient geographical allocation of economic activities across regions than their peers in the Western Europe especially because they faced the legacy of a planned economy system that determined locations for economic activities based on political decisions, not based on economic efficiency. Thus, our effort can be seen as a contribution to knowledge about agglomeration in the non-Western countries in general, and in developing regions in particular. Focusing our study on two-digit industrial sectors of 14 regions at NUTS2 level, this paper aims to identify and explain the changes regarding the evolution of industrial agglomerations in the last years across Romania compared to Bulgaria. In the end, our analysis will be able to conclude in what manner the effects of transition period influenced the patterns of industrial agglomeration in these two

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

    Full Text Available Introduction. Hepatitis E is one of the leading clinical manifestations of acute viral hepatitis in developing countries. In industrialized countries, during the past several years, sporadic “autochthonous” cases of HEV infection have been increased. Objective. The aim of this study was to analyze the epidemiological, clinical and laboratory features of HEV infection among patients hospitalized at the Department of Infectious Diseases in Military Medical Academy, Sofia, Bulgaria. Methods. A retrospective study of 806 cases of acute viral hepatitis was performed at the Department of Infectious Diseases in Military Medical Academy, Sofia, Bulgaria, between December 2004 and September 2012. The etiological diagnosis was established by ELISA. The statistical analysis was performed using Excel 2007 (Microsoft, Redmond, Washington, USA and SPSS Statistics 19.0 (IBM Corp., Armonk, New York, USA. Results. Specific reaction to anti-HEV-IgM and anti-HEV-IgG antibodies were detected in 20 (2.48% of 806 patients. The most observed clinical presentations were jaundice (85%, fatigue (85%, anorexia (65%, abdominal discomfort (55% and fever (40%. The mean values of aspartate transaminase and alanine transaminase were 521 IU/l and 881 IU/l, respectively. The cholestasis was slight, marked with mean values of gamma-glutamyl transferase and alkaline phosphatase, respectively 418 IU/l and 486 IU/l. Conclusion. We report twenty autochthonous sporadic cases of acute infection with HEV. The zoonotic etiology of the virus as well as the foodborne transmission of the infection is discussed. We found that aging and pre-existing underlying diseases are risk factors for a severe course of the HEV infection.

    This study examines ethnic, national, familial, and religious identity and well-being of 632 Roma minority and 589 majority adolescents (age: M = 15.98 years, SD = 1.34) in Bulgaria, the Czech Republic, Kosovo, and Romania. Results indicated that Roma showed lower endorsement of national identity but stronger religious identity than their majority counterparts. Path models showed positive associations of familial and religious identities with well-being, whereas Roma identity was negatively associated with well-being, particularly for Roma in Bulgaria and Kosovo (countries with a less active policy toward improving conditions of Roma). In the latter countries, Roma ethnic identity is less relevant and weakly associated with psychological well-being of youth. © 2017 The Authors.

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

I am mainly interested in (1 presenting the ethno-demographic situation and geographic distribution of ethnic groups in Romania and Bulgaria, (2 repertorying the cultural traits characteristic for homonymous ethnic groups in the two countries, and (3 synthesizing the theoretical data of current anthropological literature on the ethno-cultural variability in Southeastern Europe. In essence, my methodology compares the ethno-demographic evolution in Romania and Bulgaria (192–2011, within the legislative framework of the two countries, to map afterward the distribution of ethnic groups across Romanian and Bulgarian regions. It is on such a ground that the ethnic characters will next be interpreted as either homologous between ethno-linguistic communities bearing identical or similar ethnonyms in both countries, or as interethnic analogies due to migration, coexistence, and acculturation among the same groups, while living in common or neighboring geographical areas

    This work is an environmental isotope investigation of groundwater samples from a multi-layered aquifer system in the Lom depression of Danubian Plain in Bulgaria. Our previous studies in the Carpathian-Pannonian Region had been convinced through groundwater researches using noble gas temperatures that the recharge temperature difference between the Holocene and the late Pleistocene recharged waters is 9.13±0.89°C. The aim of this research in Bulgaria is to observe this phenomenon at the outside of the Carpathian-Pannonian Region. The purpose of the sampling campaign was to find out that one of the aquifers of the Lom depression could be a potential site for late Pleistocene, and Holocene paleoclimate reconstruction. There are water samples from the Dacian-Romanian complex, Upper-Pontian aquifer, Meotian-Lower Pontian aquitard and the Sarmatian aquifer as well. The collected water samples were examined for water chemistry, stable carbon, oxygen and hydrogen isotopes, and for noble gas concentrations, and besides them for radiocarbon and tritium. The radiocarbon content of the water samples are in the range from 15.9 pMC to 98.6 pMC. Based on the obtained radiocarbon values it can be stated that tree aquifers of four could be contain such waters which recharged during the early Holocene late Pleistocene (Pontian, Dacian, Sarmatian). There are two wells in the Pontian aquifer (Dolni Tsibar, 20.8 pMC; Agroinvest, 23.8 pMC) with lower radiocarbon content. Based on the stable oxygen composition of the Agroinvest well, which is with -14.2 ‰ more negative than the others so it can be late Pleistocene recharged water. In the Dacian aquifer might be one well, the Valchedram which can be late Pleistocene recharged with 23.7 pMC. In the Sarmatian aquifer can be find the oldest water sample from all with 15.9 pMC of Smirnenski. The obtained noble gas temperatures and tritium values might be stated this hypothesis as well. All measurements were carried out in Hertelendi

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

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

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

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

    Full Text Available Effectively tackling problems of sustainable development such as climate change, poverty, and biodiversity loss requires a different perspective on the role of science in society. Building on the understanding that knowledge production processes shall go hand in hand with governance processes, sustainability science and ecological economics promote transdisciplinarity and participatory procedures as a key requirement for scientific work on nature-society interactions. Involving non-academic actors such as local lay persons, civil society representatives, businesses, and decision makers in the research process promises the discovery of practical solutions to related problems and empowerment of communities. While this novel research approach has been increasingly applied in Western societies, its adoption by scientific actors in the context of Central and Eastern Europe, however, remains relatively low. Employing Bulgaria as a case study, this investigation examined the inter-actions between academia and practice through a series of expert interviews and a review of policy documents, thus offering insights into the specific conditions of implementing science for sustainable development. It emerges that knowledge transfer and experience exchange in the field are needed. Promoting social learning in this domain requires clarification of the roles of actors and institutions for sustainable development. Finally, recommendations for science related policies and scientific work are given.

Transects with 600 m length were walked along the banks in otter signs search. The search was stopped when the first otter signs were registered. As a whole we found domination of the very good or excellent bank tree cover. A total of 61% of transects were with tree cover between 50% and 100%. Almost equal were the stretches without or with little tree vegetation. At all transects surveyed the spraints dominated with 61%. All other otter signs were with low percentage. The otter tracks (foot prints were on second place with 20% of occurrence, followed by the food remains with 7%. At 12% of transects we did not find any otter signs. As a whole the otter was registered in 88% of transects, a sign for a good population. Highest preference we registered for walking or feeding of the otter at the open banks with no or with weak tree cover.

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

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

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

    Full Text Available The aim of this paper is to make an expert evaluation of the effects and perspectives of the impact of the Common Agricultural Policy (CAP on the development of the agricultural sector in Bulgaria, based on the empiric survey, as well as analyzing the measures for improving its influence over the economic, financial, marketing and manufacturing aspects of the development of farms. The method of expert evaluation has been used ranked depending on specific criteria. The required assessment information is achieved with the help of expert evaluations, presented on ranking scale, based on the personal preference to a specific variable of the people that participated in the inquiry. As the main characteristics of the expert evaluation, in the following study, a summarized evaluation is used of the aggregate view, as well as evaluation of the agreement of the experts who took part in the enquiry. Expert’s evaluations regarding the relative importance of the measures of the impact of the CAP for developing the farms show that the most significant influence is the manufacturing and managerial efficiency of the farms and their competitiveness. The expert evaluation shows that the improvement in the market infrastructure, the simplification of the procedures and the increase in the national additional payments are of strategic importance for the future development of the farms in the country

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

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

    There has been no study on the prevalence of dental fluorosis in Bulgaria of today where people have free access to some fluoride-containing products. The aim of the study was to investigate the prevalence of dental fluorosis among children 4 to 14 years old from the town of Dimitrovgrad, where due to unsatisfactory qualities of tap water people consume bottled water including such with fluoride levels higher than 1.5 mg/l. The study included 1504 randomly selected children. We analysed subjects with dental fluorosis according to Dean's modified criteria. The following severity levels were defined: 0 - normal; 0.5 - suspicious; 1 - very mild; 2 - mild; 3 - moderate; 4 - severe. Data were analyzed separately for the different types of dentitions. Results showed that 54.52% of all children included in the study had dental fluorosis in different degrees. Primary teeth were affected by dental fluorosis less frequently than permanent teeth (P children had fluorosis of permanent teeth only, 1.64% had dental fluorosis of primary teeth only and 12.50% had both their primary and permanent teeth affected. The proportion of individuals with the lowest degree of severity - 0.5, was the greatest both for the primary and permanent teeth. Comparison with the proportions of children with more severe degrees of fluorosis revealed significant differences (P < 0.001). The results of the study showed excessive fluoride intake during tooth development and suggested a need for further research of risk factors.

    We report our experience with puncture, aspiration, injection, and reaspiration (PAIR) for the treatment of cystic echinococcosis in Bulgaria. PAIR was performed in 230 patients with 348 echinococcal cysts. At 12-month follow-up, 77.6% of the cysts, all cystic echinococcosis (CE) 1 and CE3a cysts according to the World Health Organization Informal Working Group classification, showed various degrees of obliteration. In 11.5% of cysts, all of which were > 10 cm-type CE1, a significant amount of fluid persisted, and they were punctured again. Of those, 16 (4.6%) contained protoscolices and were treated by a second PAIR. The remaining 24 (6.9%) cysts were treated by simple aspiration or drainage. No significant reduction in size and no changes in the structure were observed in 10.9% of cysts, all of which were classified as CE2 or CE3b. Complications developed in 25.2% of patients, including severe anaphylactic reaction in two (0.9%) patients. Our experience confirms that PAIR is a successful first-choice treatment when a stage-specific approach is taken. PMID:21212200

    2016-09-01

    To become and maintain being physically active encompasses more than purely mindful and rational decision-making. Physical activity requires theoretical-methodological approaches that provide more subtle understandings of the variety of contextual factors. Nettleton and Green have recently argued persuasively for the need for the sociology of public health to embrace social practices. It is also necessary to think about the spaces, affects and technologies of engagement in physical exercise. This article examines the practices of recreational runners in Sofia, the capital of Bulgaria. The article has three aims; (i) to draw attention to the promise of non-representational theory as an additive for health research and the contextual factors of health practices, (ii) to examine recreational runner's practices and techniques of engagement in light of non-representational theory, and (iii) to highlight how interventions in Sofia and beyond can incorporate elements of non-representational theory into their strategies for improved public health. In drawing attention to the promise of non-representational theory and social practices this article concludes by emphasising their importance for public health interventions in physical activity strategies.

  12. Reconstruction of the transmission history of RNA virus outbreaks using full genome sequences: foot-and-mouth disease virus in Bulgaria in 2011.

    Begoña Valdazo-González

    Full Text Available Improvements to sequencing protocols and the development of computational phylogenetics have opened up opportunities to study the rapid evolution of RNA viruses in real time. In practical terms, these results can be combined with field data in order to reconstruct spatiotemporal scenarios that describe the origin and transmission pathways of viruses during an epidemic. In the case of notifiable diseases, such as foot-and-mouth disease (FMD, these analyses provide important insights into the epidemiology of field outbreaks that can support disease control programmes. This study reconstructs the origin and transmission history of the FMD outbreaks which occurred during 2011 in Burgas Province, Bulgaria, a country that had been previously FMD-free-without-vaccination since 1996. Nineteen full genome sequences (FGS of FMD virus (FMDV were generated and analysed, including eight representative viruses from all of the virus-positive outbreaks of the disease in the country and 11 closely-related contemporary viruses from countries in the region where FMD is endemic (Turkey and Israel. All Bulgarian sequences shared a single putative common ancestor which was closely related to the index case identified in wild boar. The closest relative from outside of Bulgaria was a FMDV collected during 2010 in Bursa (Anatolia, Turkey. Within Bulgaria, two discrete genetic clusters were detected that corresponded to two episodes of outbreaks that occurred during January and March-April 2011. The number of nucleotide substitutions that were present between, and within, these separate clusters provided evidence that undetected FMDV infection had occurred. These conclusions are supported by laboratory data that subsequently identified three additional FMDV-infected livestock premises by serosurveillance, as well as a number of antibody positive wild boar on both sides of the border with Turkish Thrace. This study highlights how FGS analysis can be used as an effective

    Full Text Available Topolnitsa Reservoir is located in a region of Bulgaria rich in copper mines where intensive mining has been ongoing for several decades. General data on the ecological status of the reservoir and the effects of metal on fish is relatively scarce. The first aim of the study was to measure the concentrations of six metals (As, Cd, Cu, Ni, Pb and Zn in water samples and in the gills of European perch (Perca fluviatilis L.. The second objective was to examine gill structure and determine the severity of histological alteration as a result of metal exposure. Surface water and fish gill samples were collected in spring, summer and autumn in 2012 and metal and histological analyses were performed. Metal concentrations in the water samples varied, but only Cu concentrations were determined in all three seasons and they were higher than the maximum permissible levels. The gill metal concentrations were significantly higher (P<0.05 than in the water. Examination of gill structure revealed the presence of proliferative and degenerative changes, as well as changes in the blood vessels. Histological lesions were similar in their severity in all three seasons. This study provides the first information about metal effects on the morphology of European perch gills from Topolnitsa Reservoir. It can be concluded that the metal contamination of the Topolnitsa Reservoir and fish is chronic and that it can negatively affect the structure and function of fish gills. As metals display a tendency to accumulate in fish gills, their effects are expected to become more severe with time, as they affect gill functions.

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

    Directory of Open Access Journals (Sweden)

    D. Pancheva

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

    Full Text Available In this paper are submitted data on longevity factors and mountain water in factorial research of phenomenon of longevity in mountainious and field areas of Bulgaria. The dependence was established among various internal and external factors on a phenomenon of longevity – residence area, health status, gender and heredity. It was shown that water is among the most important factors for longevity. Natural waters derived from various Bulgarian water springs were investigated by non-equilibrium energy (NES and differential non-equilibrium energy spectrum of water (DNES method. The biological effects of water with varrying content of deuterium are also discussed. It was shown, that the increased content of deuterium leads to physiological, morphological and cytology alterations of the cell, and also renders negative influence on cellular metabolism, while deuterium depleted water with reduced deuterium content on 20–30 % has beneficial effects on health. By using IR-spectroscopy were investigated various samples of water with varying contents of deuterium, received from Bulgarian water springs and blood serum of cancer patients as well. As estimation factor was measured the values of the average energy of hydrogen bonds (∆EH...O among H2O molecules, as well as local maxima in the IR-spectra of various samples of water and human blood serum at -0,1387 eV and wavelength 8,95 μm. For a group of people in critical condition of life and patients with malignant tumors the greatest values of local maxima in IR-spectra are shifted to lower energies relative to the control group. This testifies to the structural changes of water. The obtained results testify to necessity of consumption of clean natural water which quality satisfies mountain water from Bulgarian water springs.

    Full Text Available Seed accessions from 7 plant families and 28 species stored for above 20 years in the National gene bank of Bulgaria were evaluated. All seed accessions were maintained as base collection under long-term storage conditions with low moisture contents (5±2% in hermetically closed containers at −18°C. On the basis of experimental data, the seed storage characters σ (standard deviation of seed death in storage, P50% (the time for viability to fall to 50% and P10% (the time for viability reduction of 10% were determined allowing the prediction of seed storage life and the regeneration needs. The results showed significant differences in loss of seed viability among species and within the species. After 20–24 years of storage, eleven crops showed minimal viability decline under 5% as compared to the initial viability (oats, barley, maize, bread wheat, durum wheat, smooth brome grass, faba bean, chickpea, sunflower, cucumber and pepper. For the same storage time, another group of crops (sorghum, triticale, orchard grass, tall fescue, common vetch, grass pea, lentil, common bean, rapeseed, tobacco, flax, cabbage and tomatoes presented 5–10% reduction of seed viability. More significant changes in seed viability – above 10% – were detected for peanuts, lettuce, soybean and rye. The σ values varied from 20.41 years (Arachis hypogaea L. to 500 years (for Avena sativa L. and Triticum aestivum L. There was wide variation across species, both in time taken for the viability to fall to 50% and in time taken for the seed viability reduction of 10%. The study illustrates the positive effect of both seed storability early monitoring and prediction of regeneration needs as a tool for limiting undesired losses.

    Electricity bills may oust the government from power as it has happened in Bulgaria: Since the beginning of February 2013, the citizens of the capital city Sofia and from other cities of the Balkan Country demonstrated against the electricity bills being excessive in their opinion. Once it came to a bloody confrontation between the demonstrators and the police at the Eagle's Bridge in Sofia at 19th February, 2013, the Prime Minister Boiko Borissov and his right-wing cabinet had decided to resign. Thus, Borissov led his country into a political instability and the Bulgarian energy industry into an uncertainty on its future development.

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

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

    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.

    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.

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

    Coastal zone is among the fastest evolving areas worldwide. Ever increasing population inhabiting coastal settlements develops often conflicting economic and societal activities. The existing imbalance between the expansion of these activities, on one hand, and the potential to accommodate them in a sustainable manner, on the other, becomes a critical problem. Concurrently, coasts are affected by various hydro-meteorological phenomena such as storm surges, heavy seas, strong winds and flash floods, which intensities and occurrence frequency is likely to increase due to the climate change. This implies elaboration of tools capable of quick prediction of impact of those phenomena on the coast and providing solutions in terms of disaster risk reduction measures. One such tool is Bayesian network. Proposed paper describes the set-up of such network for Varna Bay (Bulgaria, Western Black Sea). It relates near-shore storm conditions to their onshore flood potential and ultimately to relevant impact as relative damage on coastal and manmade environment. Methodology for set-up and training of the Bayesian network was developed within RISC-KIT project (Resilience-Increasing Strategies for Coasts - toolKIT). Proposed BN reflects the interaction between boundary conditions, receptors, hazard, and consequences. Storm boundary conditions - maximum significant wave height and peak surge level, were determined on the basis of their historical and projected occurrence. The only hazard considered in this study is flooding characterized by maximum inundation depth. BN was trained with synthetic events created by combining estimated boundary conditions. Flood impact was modeled with the process-based morphodynamical model XBeach. Restaurants, sport and leisure facilities, administrative buildings, and car parks were introduced in the network as receptors. Consequences (impact) are estimated in terms of relative damage caused by given inundation depth. National depth

    Pyrite samples from the Radka epithermal, replacement type, volcanic rock-hosted copper deposit, Bulgaria, have been studied using near-infrared (IR) microscopy. Two generations of pyrite based on their textures, composition and behaviour in IR light can be distinguished. Electron microprobe analyses, X-ray elemental mapping and Fourier transform infrared spectroscopy were used to study the relationship between crystal zoning, trace element contents and IR transmittance of pyrite. The observed crystal zoning is related to variable arsenic contents in massive fine-grained and colloform pyrite from the early pyrite-quartz assemblage, and cobalt contents in pyrite crystals from the late quartz-pyrite vein assemblage. There is a negative correlation between trace element content and IR transmittance of pyrite. The IR transparency of pyrite is thus a sensitive indicator of changes in trace element concentrations. Fluid inclusions have only been found in the second pyrite generation. Scanning electron microscopy observations on open fluid inclusion cavities permitted the crystallographic features of vacuoles to be determined. A characteristic feature of primary fluid inclusions in pyrite is a negative crystal habit, shaped mainly by {100}, {111} and {210}. This complicated polyhedral morphology is the reason for the observed opacity of some isometric primary inclusions. Secondary fluid inclusion morphology depends on the nature of the surface of the healed fracture. Recognition of the primary or secondary origin of fluid inclusions is enhanced by using crystallographically oriented sections. Microthermometric measurements of primary inclusions indicate that the second pyrite generation was deposited at maximum P-T conditions of 400 °C and 430 bar and from a fluid of low bulk salinity (3.5-4.6 wt%), possibly KCl-dominant. There are large ranges for homogenisation temperatures in secondary inclusions because of necking-down processes. Decrepitation features of some of

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

    We studied both colloform-banded macro- and micro-textures as well as the composition of electrum from the epithermal Khan Krum (or Ada Tepe) gold deposit, Bulgaria (5 Mt at 5.1 g/t Au + 2.7 g/t Ag) using optical and electron scanning microscopy, vibration spectroscopy, electron micro-probe analysis, and LA-ICP-MS. The individual textural bands differ in grain size, porosity, quartz-to-adularia ratio, and abundance of electrum, pyrite, and scattered dusty opaque micro-inclusions. The individual macro-bands have formed successively via intermittent fault dilation from episodic hydrothermal pulses, as a result of regional extension and most likely originated from colloidal solutions formed by vigorous boiling during rapid pressure drop and supersaturation with respect to amorphous silica in a closed or quasi-closed hydrothermal system. Electrum is highly concentrated in the finest quartz-adularia colloform micro-bands, which fill joints with widths up to 1-2 mm. We presume that the joints have filled in with more concentrated colloidal solutions than those in the macro-bands, most likely due to extreme boiling of fluids in open or quasi-open hydrothermal system. Electrum in the micro-bands forms transverse dendrite- and chain-like aggregates as well as oval clots along the banding, all of globular morphology. We explain these locations of electrum with reorientation of aggregated electrum globules during plastic deformation of a mixed electrum-silicate gel and in result from the consequent crystallization of silicates. At the same time, electrum is not present in pores and cracks of syneresis, which indicates that it had not been a soluble phase at the time of syneresis, rather colloidal particles. Electrum also forms dense sprinkles of globular morphology deposited in open space on the surfaces of some quartz-adularia bands, due to a condensation of gaseous phase, separated during the boiling of fluids. We found that the electrum-rich quartz-adularia micro

    Our study concerns deformed gabbroic rocks from the Balkan Carpathian Ophiolite (BCO - Romania, Serbia, Bulgaria). The BCO consists of four ophiolitic massifs dismembered during Alpine tectonic and displaying together a complete classical oceanic lithosphere. Our new Sm-Nd dating on fresh lower gabbroic rocks give an accretion age for the BCO crust at 409 ± 38 Ma, in agreement with a previous age of 405 ± 3 Ma (Zakariadze et al. 2012). After removing the Alpine tectonic, the BCO appears as an elongated E-W body tilted to the south. At the base of the ophiolitic complex occurs a thin deformed zone (data indicate that their protoliths were mainly upper gabbros statically metamorphosed in the Greenschist/Amphibolite facies (event 1 = ocean-floor metamorphism at the ridge axis). These rocks have been affected by a second circulation of fluids (event 2), contemporaneous to a deformation and inducing local K-enrichment (formation of Cr-muscovite). Temperature estimates for this event indicate a range of 450°C - 280°C, with the lower values observed for the more intensively metasomatized rocks. 40Ar - 39Ar dating on two Cr-muscovites from slightly and highly deformed metagabbros gives plateau ages of 372.6 ± 1.3 Ma and 360.6 ± 1.2 Ma respectively. We interpret the first age as a mimimum age for the beginning of the event 2, observed into preserved rocks, and the second one as linked to (neo-/)recrystallisation due to localisation of the metasomatism/deformation. The interval of 30 Ma between oceanic crust accretion and initiation of metasomatism/deformation involves that the upper oceanic crust had cooled down to temperatures close to 100°C before the beginning of event 2. Consequently, a temperature increase is required to observe the greenschist facies assemblage. We have tested by tectono-thermal modelling the hypothesis that these rocks could correspond to a slice of upper crust dragged down during intra-oceanic subduction: temperatures of 450°C are reached at

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

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

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

    Two types of data sets for investigation of solar- modulated cycles in the climate of Bulgaria during the last ~ 200 years has been used in this study: 1. Instrumental data for the rainfalls and temperatures in 26 stations during the period AD 1899-1994; A smoothing dendrochronological data series of the tree rings width of a beech sample (Fagus) for the period of AD 1780-1982. The data proceedings has been provided separately for the "winter" (November-April) and "summer" (May-October) half- years. A well expressed quasi-20-22 and 54 yr cycles in the rains and temperature instrumental "summer" series as well as quasi 11yr cycle for the "winter" temeperature data has been established for the studied period 1899-1994. However there are also very serious variations of the 11 and 22 yr cycle magnitudes. The quasi 20-22 yr ("summer") cycle is weak expressed before AD 1930, while the 11 yr (winter) cycle is faded rapidly after ~AD 1975/76. The existence of 20-22 yr climatic cycle could be traced since the end of t...

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

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

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

    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.

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

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

The evolutionary lineages of Discocyclina seunesi, Orbitoclypeus multiplicatus and O. bayani are restored for the first time by using the consistent size-increase of the megalospheric embryon that also allowed introducing some new subspecies (Discocyclina seunesi beloslavensis, D. s. karabuekensis, Orbitoclypeus multiplicatus kastamonuensis, O. bayani kurucasileensis and O. munieri ponticus. By owing the most complete record of Thanetian and early Ypresian orthophragmines from the Western Tethys (using also data from SW France and the Crimean Peninsula we could reconstruct their early evolution. The chronostratigraphical position of some localities was ascertained from planktic and larger benthic foraminifera, as well as calcareous nannoplankton. In the updated orthophragminid zonation (zones are marked by OZ, OZ 1a corresponds to the early Thanetian, OZ 1b to the middle Thanetian. They are distinguished on the base of the evolution of Discocyclina seunesi. In these zones, only two unribbed species of Discocyclina and Orbitoclypeus each are present. Ribbed Orbitoclypeus, genus Asterocyclina and Nemkovella appeared in the redefined OZ 2 zone belonging to the late Thanetian. Discocyclina archiaci and D. dispansa substituted D. seunesi at about the Paleocene/Eocene boundary. The early Ypresian can be subdivided into the OZ 3 and 4 zones that can be distinguished from each other by the different

    Full Text Available The coast of the Bulgarian Black Sea is a popular summer holiday destination. The Dam of Iskar is the largest artificial dam in Bulgaria, with a capacity of 675 million m3. It is the main source of tap water for the capital Sofia and for irrigating the surrounding valley. There is a close relationship between the quality of aquatic ecosystems and human health as many infections are waterborne. Rapid molecular methods for the analysis of highly pathogenic bacteria have been developed for monitoring quality. Mycobacterial species can be isolated from waste, surface, recreational, ground and tap waters and human pathogenicity of nontuberculose mycobacteria (NTM is well recognized. The objective of our study was to perform molecular analysis for key-pathogens, with a focus on mycobacteria, in water samples collected from the Black Sea and the Dam of Iskar. In a two year period, 38 water samples were collected—24 from the Dam of Iskar and 14 from the Black Sea coastal zone. Fifty liter water samples were concentrated by ultrafiltration. Molecular analysis for 15 pathogens, including all species of genus Mycobacterium was performed. Our results showed presence of Vibrio spp. in the Black Sea. Rotavirus A was also identified in four samples from the Dam of Iskar. Toxigenic Escherichia coli was present in both locations, based on markers for stx1 and stx2 genes. No detectable amounts of Cryptosporidium were detected in either location using immunomagnetic separation and fluorescence microscopy. Furthermore, mass spectrometry analyses did not detect key cyanobacterial toxins. On the basis of the results obtained we can conclude that for the period 2012–2014 no Mycobacterium species were present in the water samples. During the study period no cases of waterborne infections were reported.

Karst. growing in the territory of State Forest Service «Garmen», «Eleshnitsa», «Yakoruda», «Dobrinishte» in Rila-Rhodope mountain region (Bulgaria. Populations are located at the southern border of species range, and protected according to Bern Convention and EC Habitat Directive 92/43. It was found that diploid set of seed progeny of P. abies from the 4 populations studied includes 24 chromosomes (2n = 2x = 24. Mixoploidy (2n = 24, 36; 2n = 24, 48; 2n = 24, 36, 48 was detected in some germinating seeds of all studied populations of P. abies. Metaphase cells of germinating seeds of P. abies from State Forest Service «Garmen» and «Eleshnitsa» contain supernumerary, or B-chromosomes, while the variability of their number and occurrence was observed. In cells of germinating seeds of P. abies from State Forest Service «Yakoruda», «Dobrinishte», B-chromosomes are not revealed. Some chromosome rearrangements such as fragments and ring chromosomes were revealed in metaphase cells of P. abies from populations of «Garmen», «Eleshnitsa» and «Dobrinishte». Probably occurrence of mixoploids, B chromosomes and chromosome rearrangements in P. abies populations growing in Rila-Rhodope mountain region is connected with adaptation of trees to the extreme environmental conditions and such a serious factor that presently forests in the studied region located in the zone of natural radioactivity and in the past, the region of study was subjected to substantial anthropogenic pressure due to uranium extraction industry.

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

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

    Full Text Available Summary. Marigold (Tagetes erecta L. is well known for its antimicrobial, antiseptic, wound and ulcer healing, antiinflammatory, antioxidant and antiviral properties, and it has a long history of being used as an herbal remedy. T. erecta L. produces a variety of substances that possess pharmacological effects and antioxidant activity. The present study was therefore aimed to analyze the antioxidant activity of extracts and fractions of T. erecta L. flowers, cultivated in Bulgaria. Radical scavenging potential was determined using two different in vitro assays. 1, 1-diphenyl-2-picrylhydrazyl (DPPH and 2, 2’-azino-bis (3-ethylbenzothiazoline-6-sulfonic acid (ABTS radicals. The ethyl acetate fraction of T. erecta L. ethanol extract was found to be the most effective in both assays, DPPH (IC50 4.3±0.4 μg/ml and ABTS (0.8±0.2 TEAC. The greatest total phenolic content was detected in EtOAc fraction from EtOH extract (517.8 mg/g GAE. It was obtained high quantity of ascorbate and ascorbate/dehydroascorbate ratio more than 1. The quantity of glutathione reduced is low and glutathione reduced/glutathione oxidized ratio was lower than 1. A correlation between radical scavenging capacities of samples with total phenolic compound content was observed. The present study revealed that the EtOAc fraction effectively show the best ability to scavenge the free radicals. Industrial relevance. Herbal medicines have gained increasing attention worldwide for the treatment of chronic diseases because of their effectiveness and small side effects as compared to synthetic drugs.Recently, an attention has been directed toward the antioxidant phytochemicals which have proved as protective against cardiovascular diseases and cancer, associated with overproduction of reactive oxygen species. The present investigations focus has been to discover plant extracts and fractions from T. erecta useful to prevent chronic degenerative diseases, especially those mediated by

    Full Text Available The aim of this research was to investigate the leaf surface microstructure, pigments spectrum, hormones status and lipids composition of halophytes Polygonum maritimum L. and Euphorbia paralias L. that grow under natural conditions on the dunes of Pomorie Lake, (Bulgaria. It was shown that the existence in saline and dry soils provided among others adaptive mechanisms by specific microstructure of leaf. The adaxial and abaxial surfaces of P. maritimum leaves are covered with a dense layer of cuticle wax, stomata are located on the leaf both sides below the cuticle level. In E. paralias the cuticle is also well developed on the adaxial surface of leaf laminas. The epidermis of the leaf lower side is covered with a less dense cuticle layer formed by large wax crystals. This plant has stoma pores only on the abaxial side of small leaves below the cuticle level and they are surrounded with hump-shaped cuticle constructions. A high amount of carotenoids (as compared with that of chlorophylls in P. maritimum leaves indicates that these pigments have a light-collecting function and could transfer an additional energy to chlorophylls. The high performance liquid chromatography method has been used to provide a qualitative and quantitative analysis of hormones. It was shown that in leaves of E. paralias and P. maritimum free abscisic (ABA and conjugated indole-3-acetic (IAA acids prevailed. A high level of active ABA is correlated with the salt tolerance and ability to survive and grow in stress conditions. A high level of conjugated form of IAA demonstrated that activity of this hormone is limited. The cytokinins qualitative and quantitative analyses demonstrated that in E. paralias leaves zeatin forms dominated, and the level of inactive cytokinins (cis-zeatin and zeatin-O-glucoside was much higher than that of active ones (trans-zeatin and zeatin riboside. P. maritinum leaves contained a significant quantity of isopentenyl forms

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

    2011-12-01

    Full Text Available The article decribes and discusses remains of late Pliocene (middle Villafranchian cheetah, Acinonyx pardinensis (Croizet et Jobert from Varshets, N.-W. Bulgaria. It is accepted that three chronoforms A. pardinensis pardinensis, A. p. pleistocaenicus and A. p. intermedius succeed in Europe from the Early Villafranchian (Etouaires, approx. 2.6 Ma till the Middle Pleistocene. Remains are scarce and at this level of knowledge we could accept the recently proposed subspecific status of all these forms but their taxonomical relations could be rather more complicate. The remains from Varshets correspond to the earliest form A. pardinensis pardinensis which inhabited Eurasia during the late Early and the Middle Villafranchian and the beginning of the Pleistocene. Other European remains of A. p. pardinensis are known only from Spain, France, Italy and the Azov region of Southern Russia. It seems that then the species occupied only the southern part of the European continent (the Mediterranean-Balkan-Northern peri-Pontic area, and from there it probably spread till Central Asia (Tajikistan. Such a distribution supports the concept of the faunal entity of South Europe in Villafranchian time as well as the theory for the Central Asian influence of this fauna mainly trough the Balkans by two ways: via Bosphorus and via the peri-Pontic area. According to the paleontological data the fossil Acinonyx does not reach Central Europe (Austria and Germany before the Epivillafranchian, possibly after new waves of dispersal of another, Early Pleistocene form of Central Asia. The relationship of the Middle Villafranchian A. pardinensis with the rather contemporaneous forms from China (Hezheng “Sivapanthera” linxiaensis and A. kurteni and from Siwaliks is not clear, but the Chinese forms must represent taxa different from A. pardinensis. Acinonyx s. str. is characterized by strongly domed and enlarged frontal area, shortened skull and downwards inclined

    2003-04-01

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

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

    Vlaykov Vruh-Elshitsa represents the best example of paired porphyry Cu and epithermal Cu-Au deposits within the Late Cretaceous Apuseni-Banat-Timok-Srednogorie magmatic and metallogenic belt of Eastern Europe. The two deposits are part of the NW trending Panagyurishte magmato-tectonic corridor of central Bulgaria. The deposits were formed along the SW flank of the Elshitsa volcano-intrusive complex and are spatially associated with N110-120-trending hypabyssal and subvolcanic bodies of granodioritic composition. At Elshitsa, more than ten lenticular to columnar massive ore bodies are discordant with respect to the host rock and are structurally controlled. A particular feature of the mineralization is the overprinting of an early stage high-sulfidation mineral assemblage (pyrite ± enargite ± covellite ± goldfieldite) by an intermediate-sulfidation paragenesis with a characteristic Cu-Bi-Te-Pb-Zn signature forming the main economic parts of the ore bodies. The two stages of mineralization produced two compositionally different types of ores—massive pyrite and copper-pyrite bodies. Vlaykov Vruh shares features with typical porphyry Cu systems. Their common geological and structural setting, ore-forming processes, and paragenesis, as well as the observed alteration and geochemical lateral and vertical zonation, allow us to interpret the Elshitsa and Vlaykov Vruh deposits as the deep part of a high-sulfidation epithermal system and its spatially and genetically related porphyry Cu counterpart, respectively. The magmatic-hydrothermal system at Vlaykov Vruh-Elshitsa produced much smaller deposits than similar complexes in the northern part of the Panagyurishte district (Chelopech, Elatsite, Assarel). Magma chemistry and isotopic signature are some of the main differences between the northern and southern parts of the district. Major and trace element geochemistry of the Elshitsa magmatic complex are indicative for the medium- to high-K calc-alkaline character of

    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.

  17. Late Cretaceous structural control and Alpine overprint of the high-sulfidation Cu-Au epithermal Chelopech deposit, Srednogorie belt, Bulgaria

    The Chelopech epithermal high-sulfidation deposit is located in the Panagyurishte ore district in Bulgaria, which is defined by a NNW alignment of Upper Cretaceous porphyry-Cu and Cu-Au epithermal deposits, and forms part of the Eastern European Banat-Srednogorie belt. Detailed structural mapping and drillcore descriptions have been used to define the structural evolution of the Chelopech deposit from the Late Cretaceous to the present. The Chelopech deposit is characterized by three fault populations including ˜N55, ˜N110, and ˜N155-trending faults, which are also recognized in the entire Panagyurishte district. Mapping and 3-D modeling show that hydrothermal alteration and orebody geometry at Chelopech are controlled by the ˜N55-trending and ˜N110-trending faults. Moreover, the ˜N155-trending faults are parallel to the regional ore deposit alignment of the Panagyurishte ore district. It is concluded that the three fault populations are early features and Late Cretaceous in age, and that they were active during high-sulfidation ore formation at Chelopech. However, the relative fault chronology cannot be deduced anymore due to Late Cretaceous and Tertiary tectonic overprint. Structurally controlled ore formation was followed by Senonian sandstone, limestone, and flysch deposition. The entire Late Cretaceous magmatic and sedimentary rock succession underwent folding, which produced WNW-oriented folds throughout the Panagyurishte district. A subsequent tectonic stage resulted in overthrusting of older rock units along ˜NE-trending reverse faults on the Upper Cretaceous magmatic and sedimentary host rocks of the high-sulfidation epithermal deposit at Chelopech. The three fault populations contemporaneous with ore formation, i.e., the ˜N55-, ˜N110- and ˜N155-trending faults, were reactivated as thrusts or reverse faults, dextral strike-slip faults, and transfer faults, respectively, during this event. Previous studies indicate that the present-day setting is

    This report gives the result of a bilateral comparison of capacitance between the BIM (Bulgaria) and the BIPM carried out in 2012. Two 100 pF travelling standards belonging to the BIPM were used. The comparison was carried out with an 'A-B-A' pattern of measurements; the standards were measured first at the BIPM for a period of about one month, then for a similar period at the BIM, and finally again at the BIPM. The measurand was the two terminal-pair capacitance at a frequency of 1000 Hz and for a measuring voltage of 15 V. The BIPM was the pilot laboratory, and the comparison forms part of the ongoing BIPM key comparison BIPM.EM-K14.a. The results from the BIM and the BIPM were found to be in good agreement, with a difference smaller than the relative expanded uncertainty (95% confidence, k = 2) of 1.1 × 10-6. Main text.

    Systematic environmental screenings are still the exception in South-Eastern Europe. Especially, there is a decisive lack of information concerning the occurrence and behaviour of xenobiotic and toxic compounds like volatile- and non volatile halogenated organics, suppressed by the surrogate AOX, synthetic chelating agents, pesticides, like DDT as well as chlorate in the biosphere. The analysis of soils, waters, and firns of a representative area in Bulgaria, the Pirin mountains, indicate a relatively low back ground pollution. The accumulation of the xenobiotics in this high mountain region is recognised to be low. Nevertheless, traces of pesticides and chelating agents like EDTA and NTA in ice (firns) and soils were found. The surrogate AOX should be a parameter, suitable for routine environmental screenings of such areas. (orig.)

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

    Full Text Available Chilean Patagonia has protected mountainous areas with evergreen native forests; in which the lakes and rivers, of volcanic or glacial origin, are oligotrophic. In Bulgaria, there are mountainous zones with native forests and associated lakes of volcanic origin. The aim of the present study is to carry out a preliminary comparison of zooplanktonic crustaceans in lake ecosystems associated with native forests of Chilean Patagonia and of Bulgarian mountains. The study revealed that the lakes studied in Chilean Patagonia are associated mainly with Nothofagus forests; they are oligotrophic, with a low number of zooplanktonic crustacean species. Similar results were observed for Bulgarian mountain lakes associated with Fagus forests. A null model analysis of species co-occurrence was applied to the two groups of lakes, and the result revealed the absence of regulatory factors in species associations. These studies agree with similar descriptions of lakes in Andean Patagonia and New Zealand. They highlight the important role of native Nothofagus forests in Argentina and Chile, and of Fagus forests with associated soil properties in Bulgaria, in the oligotrophy of the lakes studied.La Patagonia de Chile tiene una serie de áreas protegidas con bosques nativos perennes asociados a lagos y ríos oligotróficos y de origen glacial.

    2017-02-01

    Full Text Available In addition to the emergency medical services the victims of various disasters and accidents need to keep their dignity as human beings. Dignity is a term used in morals and ethics to designate that people have the right to be respected and treated ethically. Providers of emergency medical services perform their activities in compliance with the rules of good medical practices while keeping professional secrecy and observing patient rights. Patient rights and in particular moral rights ensure respect for patients’ lives and dignity in the health care system. The aim of the research is to study the ethical dilemma of saving patients’ lives and protecting their dignity in cases of emergency. The purpose of the survey is to study the medical, ethical and legal aspects of the issue. A documentary method of collection data from scientific sources is used with regard to the different aspects of the topic. In a number of cases during their routine medical practice, especially in emergencies, medical experts have to make their choice of medical behavior – whether it has to comply with ethics or law. Making the right decision and choice of behavior depends on the moral values, professional training, knowledge of legal requirements and personal qualities of the relevant medical professional. One should always take into account that protecting victims’ dignity is especially important in emergencies when they feel most vulnerable.

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

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

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

    2016-03-01

    Full Text Available Corruption in the healthcare sector is a reflection of the structural challenges in the health care system. The problem of corruption in healthcare is of a multidimensional nature. The Bulgarian health care system is based on a regulated regime. On one hand there is the functioning of a state-owned and state-controlled health fund financed through obligatory contributions by all income earners, and on the other, a union of health providers that negotiate a national framework health contract with the fund. Causes of corruption are classified as different factors such as structural factors and government policies factors. The health sector is susceptible to corruption for various reasons, mostly related to its organization. The health sector is a complex sector. In order to be effective, reforms to combat corruption must be informed by theory, guided by evidence and adapted to context. It is necessary to review and develop diagnostic and treatment algorithms as standards of good medical practice, which would help to assess the package of medical and non-medical activities.

Salmonella serovars are responsible for human diseases that range from localized gastroenteritis to systemic infections. The aim of the present study was to investigate the susceptibility of Salmonella strains, isolated from food and infectious processes, to the antibacterial action of Brazilian and Bulgarian propolis, as well as to determine the behavior of these bacteria, according to the incubation period, in medium plus propolis. Dilution of ethanolic extract of propolis in agar was the used method. Brazilian and Bulgarian propolis showed an antibacterial action against all Salmonella serovars. The minimal inhibitory concentrations (MIC of propolis were similar, although they were collected in different geographic regions. Salmonella typhimurium, isolated from human infection, was more resistant to propolis than Salmonella enteritidis.

    The mineralogy, elemental composition and modes of occurrence of 49 elements in nine composite samples of Bobov Dol high-ash coals were studied by optical microscopy, scanning and transmission electron microscopy, X-ray diffractometry and chemical analysis. The major minerals were quartz, kaolinite, illite, plagioclase and K-feldspar and the minor minerals and phases were pyrite, marcasite, siderite, calcite, dolomite, gypsum, muscovite, montmorillonite and volcanic glass. The accessory minerals include a wide variety of minerals, such as galena, pyrrhotite, magnetite, hematite, goethite, chromite, rutile, anatase, corundum, gibbsite, biotite, chlorite, zircon, enstatite, garnet, jarosite, alunite, barite, polyhalite, aragonite, ankerite, witherite, apatite, halite and sylvite. The modes of occurrence and some genetic peculiarities of the above-mentioned minerals are described. Thirty-three elements occurred in concentrations higher than the respective Clarke values; especially S, Rb, Nb, Hf, Zn, Cu, Pb, Mn, Ti and U. The concentration trends and modes of occurrence of the trace elements are also discussed. In decreasing order of significance, the trace elements probably occur as element-organic compounds, as impurities in the mineral constituents, as major components in the minerals, as major and impurity components in the inorganic amorphous constituents, and in the fluid constituents. The Bobov Dol coals have undergone complex syngetenic, diagenetic and epigenetic mineralization processes associated with hydrothermal and volcanic activities. These processes were also accompanied by intensive tectonic movements, and possibly, by a later change from continental to marine sedimentation in the area after burial of the coal. 38 refs., 1 fig., 6 tabs., 5 plates.

    Chromatographic separation and mass spectral studies of bitumens extracted from lithotypes (humovitrain, xylain, liptain and humoclarain) from the Miocene Maritza-Iztok lignite reveal the following: (1) A preponderance of the {alpha}-phyllocladane skeleton over the pimaranes/abietanes. The variety of tricyclic diterpanes confirms that the generation biota included gymnosperms; (2) The presence of dicotyledonous angiosperms in the generation biota is indicated by the occurrence of widely distributed des-A-lupane structure; (3) The dominance of terpanes over steranes confirms the prevailing contribution of terrigenous input; (4) The preponderance of C{sub 27{beta}} hopane and the presence {beta}{beta} hopanes indicates a low degree of thermal maturation. 23 refs., 6 figs., 4 tabs.

    Full Text Available The paper analyses the hotel service-performance process in Bulgarian hotels, which is based on the results of the research about tourists’ opinion on basic moments in service process. One of the most important characteristics of hotel industry is the leading role of the human factor in service-performance process. It cannot be accomplished without the participation of the customer and without the participation of the staff.This makes the evaluation of service process strongly subjective. Because of this, customer needs satisfaction is a big challenge for the hotel management. Under the present conditions of an increased competition, satisfying customers means offering service-performance process, which not only meets, but also exceeds guests’expectations. This can be achieved by a preliminary study of their requirements and expectations.

    Full Text Available Introduction One-year mortality in COPD patients is reported to be between 4% and 43%, depending on the group examined. Aim To examine the one-year mortality in COPD patients after severe exacerbation and the correlation between mortality and patients’ characteristics and comorbidities. Methods A total of 152 COPD patients hospitalized for severe exacerbation were assessed for vitamin D status, diabetes mellitus (DM, arterial hypertension (AH, and metabolic syndrome (MS. Data were gathered about smoking status and number of exacerbations in previous year. CAT and mMRC questionnaires were completed by all patients. Pre- and post-bronchodilatory spirometry was performed. One-year mortality was established from national death register. Results One-year mortality is 7.2%. DM, MS, and VD are not predictors for one-year mortality. However there is a trend for increased mortality in patients with AH (9.5% vs. 2.1%, p = 0.107. There is increased mortality in patients with mMRC > 2 (11.1 vs. 0%, p = 0.013. The presence of severe exacerbation in the previous year is a risk factor for mortality (12.5% vs. 1.4%, p = 0.009. There is a trend for increased mortality in the group with FEV1  80% may be factors for good prognosis. Risk factors for increased mortality are age, FEV1 value, severe exacerbation in previous year and reduced quality of life.

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

    The mineral and inorganic chemical composition of five types of samples from the Pernik subbituminous coals and their products generated from the Pernik preparation plant were studied. They include feed coal, low-grade coal, high-grade coal, coal slime, and host rock. The mineral matter of the coals contains 44 species that belong mainly to silicates, carbonates, sulphates, sulphides, and oxides/hydroxides, and to a lesser extent, chlorides, biogenic minerals, and organic minerals. The detrital minerals are quartz, kaolinite, micas, feldspars, magnetite, cristobalite, spessartine, and amphibole. The authigenic minerals include various sulphides, silicates, oxihydroxides, sulphates, and carbonates. Several stages and substages of formation were identified during the syngenetic and epigenetic mineral precipitations of these coals. The authigenic minerals show the greatest diversity of mineral species as the epigenetic mineralization (mostly sulphides, carbonates, and sulphates) dominates qualitatively and quantitatively. The epigenetic mineralization was a result of complex processes occurring mostly during the late development of the Pernik basin. These processes indicate intensive tectonic, hydrothermal and volcanic activities accompanied by a change from fresh to marine sedimentation environment. Thermally altered organic matter due to some of the above processes was also identified in the basin. Most of the trace elements in the Pernik coals (Mo, Be, S, Zr, Y, Cl, Ba, Sc, Ga, Ag, V, P, Br, Ni, Co, Pb, Ca, and Ti) show an affinity to OM and phases intimately associated with OM. Some of the trace elements (Sr, Ti, Mn, Ba, Pb, Cu, Zn, Co, Cr, Ni, As, Ag, Yb, Sn, Ga, Ge, etc.) are impurities in authigenic and accessory minerals, while other trace elements (La, Ba, Cu, Ce, Sb, Bi, Zn, Pb, Cd, Nd, etc.) occur as discrete phases. Elements such as Sc, Be, Y, Ba, V, Zr, S, Mo, Ti, and Ga exceed Clarke concentrations in all of the coal types studied. It was also found that a number of elements in the Pernik coals (F, V, As, Pb, Mo, Li, Sr, Ti, Ga, Ni, Ge, Cr, Mn, etc.) reveal mobility in water and could have some environmental concerns. (author)

    The Foundations works of the bridge over the the Danube River II has involved a new technical challenge due to the cathartics of depth and diameter of the piles, and the logistical and human, due to the hard environmental conditions for the execution. This work, awarded to FCC. Construction company in its two contracts. Access to the bridge and Main Bridge has required on the differenced sites, the use of a wide range of foundation systems, since driven precast piles to in in situ pile with permanent casing, installed by vibrating systems and excavated with benoto grabs systems. The enormous responsibility of this phase is evident in the intense camping of characterization tests with static load tests, dynamic and Osterberg cells, as well as control the campaign with Cross-hole tests in 100% of the piles in situ executed, that has allowed no only ensure the highest level of quality on the foundation elements, but also to take the most of the mechanical characteristics of soils provided. The complexity of the execution of more than 24,000 ml pile executed along the more than 2 years duration of the work reach the maximum expression in the more than 6,900 ml of in situ pile made from marine resources, with a maximum depths up to 80 m with 2 m diameter pile. The article intends to give an overview of the site and the execution, associating the different foundation methods used, and the problems that were detected. (Author)

    Full Text Available Communication requires unconditional respect for the other. Acknowledging the qualities of the people   is a basis for good communication.  Communication starts when you accept the people the way they are. The social, economic and technical development provides opportunities for good professional realization of people with special educational needs.  The resistance, striving for “survival” and successful “introduction” into the social life are a prerequisite for success. The people who are stigmatized and their families are aware that once they have been labeled, they should have to overcome this stigma and to take the maximum possible good out of this label. Positive stigma stimulates the people with disabilities seek more contacts, to become more independent and to realize themselves adequately in the social life. The survey of attitudes and motivation scale contact with people with disabilities give reliable information about what is the attitude of students towards people with disabilities and what were their contacts. The successful integration into society of people with special educational needs depends also on the perceptions and attitudes of the professionals who work with them too. Undoubtedly, the attitudes and models for the disabled people change and will continue to change. In this context the disabled people should develop social identity and public awareness, but not only in their stigmatized group, but in a broad social aspect.

The grasshopper associations in the pellets specify foraging mainly in mesophytic grasslands that usually replace abandoned fields and overgrown pastures with a low level of grazing. The xerophytic grass-shrubby habitats, not rare on stony terrains, were of less importance, providing around 20% by prey. The typical aquatic inhabitants and the use of carrion around villages were exceptions in the study diet. The number of innutritious materials in the pellets rose when the White Storks hunted on nippy and agile grasshoppers and decreased when the main pray was slower beetles taken from the ground. The roosting of non-breeding White Storks disappeared when their preferred feeding habitats were ploughed up in the following years.

    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 article makes an attempt to study the regimes of using of and living in the city - world cultural heritage in two different political and economic contexts. The pressure of the tourism industry on the value, which was visible even in the years of the late state socialism, became irresistible after 1989 in the context of the liberalised market economy, the interests of the private investors and the accepted as part of the "normal" market order corrupt practices of the institutions that are responsible for the safeguarding and management of the cultural heritage. The ethnographic study argues that intertwined in a Gordian knot around the central question for the residents of the ancient city of Nessebar, viz. the occupation of the city, which has been declared a world heritage site, are issues like trust and distrust in the institutions, the experience of abiding by formal and informal rules for operation with private property, the notions of social justice, local identity, the use of the cultural heritage as symbolic capital by different social actors and its transformation into economic one, with the conflicting interconnection between tourist industry and cultural heritage.

    Soft types, humus types and vegetation as well as their hypsometric variation were analysed in terms of sequences in the northern part of the high mountains of the Pirin National Park at altitudes between 1000 and 2400 m a.s.l. The study area is characterised by a large variety of natural parameters like petrology (mainly marble and granite), morphology (different slope deposits, exposition) and the orographic climate gradient. Statistical analyses using these parameters provided a basis for the soil group classification of the sites. Based on a Digital Terrain Model (DTM) and a geological map of the Pirin National Park, the results of these statistical analyses were used to generate a "map of potential soft groups" (regionalisation using GIS). Six potential soil groups could be determined. The resulting map exhibits a confidence level of 68% on 74.4% of the covered area. Rendzic Leptosols, in combination with Folio Histosols and Histi-lithic Leptosols occur in the alpine and subalpine regions on calcareous substrates. With decreasing altitude they are replaced by a mosaic of Rendzic Leptosols, Phaeozems and an increasing occurrence of Cambic Umbrisols. Umbrisols found on silicatic substrates in the alpine region are replaced by Cambic Umbrisols with decreasing altitude as well. Hence, pedogenesis is characterised by increasing browning and depth of the soil profiles with decreasing altitude. The pH-level is slightly acidic to neutral in lower zones and on calcareous rocky bases. Acidification increases in the subalpine zone. Soft pH decreases down to 4 on silicate subtrates. Typical humic values in mineral topsoils are 10 to 12%, and in organic layers of the softs above 2000 m a.s.l, they are even more. The C:N ratio closely ranges around 20 (median).

A sampling procedure based on the irregular grid of points and validated analytical methods were used in the field and laboratory studies. It is found that Cd content varies from 0.21 to 0.90 mg kg-1 in studied soils and the average value of 0.55 mg kg-1 coincides with concentration demarcating soil pollution (0.5 mg kg-1. Co content ranges from 2.22 to 15.76 mg kg-1 and in 70 % of sampled points exceeds the natural background content of 7.8 mg kg-1 found in local rocks. Still, Cd enrichment of studied soils is more significant than Co’s with coefficient of Clarke concentration of 3.67. Hence, the secondary deposition of studied elements as a result of the Bobov dol Thermal power plant air emissions is verified by results obtained. The spatial distribution of Cd and Co is featured with an altitudinal gradient in deposition and a trend of quantitative depletion in the South of Plant. Soil organic matter and pH have no influence on the content and spatial distribution of studied elements. Elements iron affinity governs their geochemical linkage in soils although cobalt occurs allied with aluminum and titanium.

    To establish mean and reference range of basal serum Anti-Mullerian hormona (AMH) levels in a group of healthy fertile Bulgarian women. The present report covers the results of 9 month's period in which 72 healthy fertile Bulgarian women, aged 20-40 years were selected to determinate a reference group of healthy fertile women with normal values of AMH. Blood samples were collected on early follicular phase of menstrual cycle (2-4 days). AMH was analyzed in duplicate with the use of a double-antibody ELISA. We established mean values of AMH -1,46 +/- 0,93 in a group of healthy fertile Bulgarian women with mean 31,4 years of age. The values of AMH, which we obtained in the 10th percentile, 10th - 0,61 ng/ml and in the 90th percentile was 2.94 ng/ml. The measurement of AMH is a test easy for performance, with reference values for healthy fertile Bulgarian women -1,46 +/- 0,93 ng/ml.

    Full Text Available Three native populations of A. melanostomus from different Bulgarian habitats were analysed, in view to their morphologic, biochemical-genetic variability and resistance in salinity alterations. Freshwater specimens can survive when fresh water (0‰ is changed rapidly by Black Sea water (16-18‰ and marine vice-versa. In view of the salinity resistance A. melanostomus is evaluated as tolerant. Eleven non-enzymatic and 16 enzymatic loci were tested as genetic markers for population identification. Most of them were monomorphic for all populations analysed, with exception of esterases and malate dehydrogenase. These two polymorphic enzyme systems could be used for further analyses of population structure of A. melanostomus. The genetic diversity DNeicompared between three populations was low - 0.005-0.016 and the sample from Durankulak occurred to be more genetically divergent. The morphological and biochemical-genetic variability characteristics of the studied populations do not show correlation, but independently vary according to different environmental factors.

    2012-04-01

    Full Text Available The paper discusses the main results from the first ranking system of Bulgarian higher education institutions. It adopts two perspectives: 1 from the point of view of higher education – What are the basic achievements, problems and perspectives of Bulgarian higher education as seen through the prism of the ranking system? 2 from the point of view of the ranking system – What are the strengths and weaknesses of the ranking systems and how it can be further developed and improved? The paper argues that ranking systems of higher education institutions are an inevitable result of massification, commercialization and growing competition in higher education. The analysis highlights the critical arguments against the first ranking system of Bulgarian higher education institutions and suggests some possibilities for its future development. On the basis of the results from the ranking system the paper outlines the main problems of the Bulgarian higher education. It discusses massification of Bulgarian higher education in the light of recent trends in other European countries and European educational policies. It is argued that Bulgarian higher education is in need of elaboration of strategic vision and new normative framework. It also needs changes, such as: establishment of new governance model and new model of financing of higher education; strengthening the relationship between teaching and research; development of the capacity of higher education institutions for innovative and strategic thinking; diversifying the system of higher education; development of strategic partnerships between higher education institutions and between them and non-academic partner.

    2012-07-01

    Full Text Available Background: Asian medicinal plants are an integral part of the Bulgarian traditions and folk botanical knowledge and as from the past until now, have their place in the Bulgarian market. In the last decade the interest in new plant-based products has increased. Materials and Methods: This study was conducted with the aim to bring out the facts about the diversity of Asian medicinal plants, present in medicinal plant-based products that are recently available on the Bulgarian market. The survey data was gathered during a period of 7 years (2003-2010 from the main national databases that contain information about herbal medicines and interviews, along with field-collected data. Results: More than 185 species of medicinal plants, belonging to 38 families and 137 genera were registered. Only twenty species were found to be used mostly in plant-based products for example Panax ginseng, Eleuterococcus senticosus, Ginkgo bilоba, Camellia sinensis, Zingiber officinale, Rhodiola rosea, Euphorbia pallasii, Scutelaria baicalensis, Garcinia cambogia, Hibiscus spp., Cinnamomum verum, Piper nigrum, Curcuma zedoaria, Syzigium aromaticum, etc. Most of them can be compounds of plant extract products, herbal remedies, spices, food and food additives, which are mainly proved to be beneficial as immune stimulants, memory enhancers, antitumor agents, sedatives, aphrodisiacs, antimycotics, wellness tea, body weight reducers, stimulants, blood pressure reducers, etc. Conclusions: Some of the species were used in the past for different purposes, while others are completely unknown and exotic. The occurrence of new combinations and mixtures containing both traditional Bulgarian and Asian folk medicine herbs was observed. This particular way of development, of traditional medicine in modern life, is of special interest to the ethnobotanists and is discussed further in the study.

    2016-02-01

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

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

    Pavlova, Dolja; Karadjova, Irina

    2013-12-01

    Populations of medicinal plants growing on serpentines and their respective soils were analyzed for Fe, Ni, Mn, Cr, Co, Cd, Cu, Zn, and Pb using inductively coupled plasma atomic emission spectrometry. Aqua regia extraction and 0.43 M acetic acid extraction were used for the quantification of pseudototal and bioavailable fractions, respectively, of elements in soil and nitric acid digestion for determination of total element content in plants. Screening was performed to (1) document levels of toxic metals in herbs extensively used in preparation of products and standardized extracts, (2) compare accumulation abilities of ferns and seed plants, and (3) estimate correlations between metal content in plants and their soils. The toxic element content of plants varied from site to site on a large scale. The concentrations of Fe and Ni were elevated while those of Cu, Zn, and Pb were close to average values usually found in plants. The highest concentrations for almost all elements were measured in both Teucrium species. Specific differences in metal accumulation between ferns and seed plants were not recorded. The investigated species are not hyperaccumulators but can accumulate toxic elements, in some cases exceeding permissible levels proposed by the World Health Organization and European Pharmacopoeia. The harvesting of medicinal plants from serpentines could be hazardous to humans.
