Sample records for bulgarian organizations

  1. Territorial Dioceses and Ethnic Episcopies in the Structure of the Church Organization of the First Bulgarian Kingdom (Canonical Aspects

    Directory of Open Access Journals (Sweden)

    Archpriest Alexander Zadornov

    2016-11-01

    Full Text Available The coexistence of ethnic and territorial principles in the structure of ecclesiastical organizations is a well known fact in church history. Both principles are equally legitimate from the point of view of canonical law. The “ethnic principle” was based on legal norms of the so-called 34th Apostolic Rule, and contrary to the opinion of scholars of the 19th century, it was still in use after the era of the Ecumenical Councils. This fact must be considered by students of the history of Church organizations in the First Bulgarian Kingdom, too. The observations regarding the structure of church organizations in Simeonic Bulgaria make it possible to assume the coexistence of ethnic and territorial principles of church organizations in his kingdom. As is known, Slavonic church schools were established in the southwestern part of the First Bulgarian Kingdom after 886. They were aimed at training the Slavonic clergy for the Slavonic church organization. In 893, the Bulgarian King Simeon was elevated to the throne, and a Slavonic eparchy headed by St. Clement of Ohrid was established in the southwestern territories of the First Bulgarian Kingdom. As a result, heterogeneous church organizations were established in the region, and church structures of ethnic and territorial types appeared. They differ from each other by the language of their church services. Old Church Slavonic must have been used as a liturgical language in the ethnic Slavonic eparchy. Since direct historical evidence for such heterogeneous church structure in the First Bulgarian Kingdom is absent, new interpretations of sources made on the basis of canonical law can be of importance for Slavonic studies.

  3. Ivan Zajc's Bulgarian Songs

    Full Text Available On the basis of newly discovered historiographic documents, this study traces the »biography« of Ivan Zajc’s Bulgarian songs. It specifies some disputed details with regard to the numbering and structure of two vocal cycles; it submits a transcript of a music sheet of the song Robstvo (The Yoke, op. 843a and the original of an unknown composition Majko kleta (Poor Mother on the verses of the Bulgarian poet Ivan Vazov which has not been registered by Hubert Pettan in Zajc’s catalogue of works. This exploration, together with the historiographic focus, highlights the connection of these opuses with the Bulgarian poetry which gained wide popularity through the anthology Bulgarian Songs by August Harambašić. Indeed, some details which Zajc indicated on the title pages of his scores, lead to this assumption. At the same time, the spread of the songs in Bulgaria indicates the connection of the Croatian composer with Bulgarian musicians, choral societies, schools etc., as a result of which in the first decade of the 20th century Zagreb’s Hrvatski glazbeni zavod became an attractive educational centre for many young Bulgarian people. Ivan Zajc’s Bulgarian Songs have not only enriched the artistic repertoire of Bulgarian choral societies. They outline one of the lines of active multicultural transfer between Bulgaria and Croatia on the border between the last decades of the 19th and the beginning of the 20th centuries. The melodies of his marches, creating the spirit of the struggles for national liberation of Bulgarian nation, have become part of the newly created national musical culture and have been often accepted as Bulgarian in their origin.

    Full Text Available A review of several studies of teachers’ career motivation since Bulgarian Renaissance till nowadays is presented in this paper. 203 Bulgarian teachers in public schools were studied by means of a questionnaire created by Slavchov & Stoyanova (2007 measuring career motivational types, according to Moses’ typology (2003. The career motivational type of Authenticity seekers was the most preferred by the studied Bulgarian teachers, followed by Personal developers and Stability seekers. Career builders as a career motivational type was minor career motivator, the least preferred one by Bulgarian teachers. A lot of significant positive correlations existed between teachers’ career motivational types. Some social-demographic factors (such as gender, specialty, work experience, and age differentiated teachers’ career motivators. The type of Autonomy seekers was more preferred career motivator by male teachers than by female teachers in correspondence to the traditional stereotypes for men. Longer teachers’ work experience and teachers’ advance in age were related to more frequency of Stability seekers, but less frequency of Novelty seekers career motivator. Preschool and elementary school teachers preferred more strongly Authenticity seekers as a career motivator than teachers in natural sciences and mathematics. Establishing major career motivators for teachers may be related to opportunities for improvement of performance and work satisfaction.

    Full Text Available Affirmation Modality in Bulgarian, Macedonian and Serbian In the case of affirmation modality the speakers transform their utterances by stressing or attributing a positive value as an additional component added to the semantic structure of a proposition. This type of affirmative polarization is triggered in opposition to negation or hypothetically negative contexts. The goal of the present paper is twofold: on the one hand to compare and contrast affirmative periphrastic constructions in Bulgarian, Macedonian and Serbian and, on the other hand, to ascertain what these constructions reveal regarding the organization of grammatical categories in general and the status of affirmation modality as a coherent and homogenous category with a linguistic validity.

Tzoneva is being elaborated based on a working Polish-Bulgarian-Russian electronic parallel corpus authored by Maksim Duszkin, Violetta Koseska-Toszewa and Joanna Satoła-Staśkowiak, and works by A. Tzoneva. It is the first corpus comparing languages belonging to three different Slavic language groups: western, southern and eastern. Works on the dictionary are based on Gramatyka konfrontatywna bułgarsko-polska (Bulgarian-Polish confrontative grammar and the proposed there semantic-oriented interlanguage. Two types of classifiers have been introduced into the dictionary: classic and semantic. The trilingual dictionary will present a consistent and homogeneous set of facts of grammar and semantics. The Authors point out that in a traditional dictionary it is not clear for example whether aspect should be understood as imperfective / perfective form of a verb or as its meaning. Therefore in the dictionary forms and meaning are separated in a regular way. Imperfective verb form has two meanings: state and configuration of states and events culminating in state. Also perfective verb form has two meanings: event and configuration of states and events culminating in event. These meanings are described by the semantic classifiers, respectively, state and event, state1 and event1. The way of describing language units, mentioned in the article, gives a possibility to present language material (Polish, Bulgarian, Russian in any required order, hence the article’s title.

  16. The gender in Bulgarian proverbs

    Directory of Open Access Journals (Sweden)

    Uzeneva Elena

    2005-01-01

    Full Text Available We have chosen the paremiology as the object of this article because it is the area where phraseology and folklore are closely related. This fact makes the study of proverbs significant from the lingua-cultural point of view. The subject of the Bulgarian proverbs is an important source of interpretation because most proverbs are "prescriptions-stereotypes of folk self-consciousness" (Telija. We can see proverbs as cultural stereotypes reflected in common language. The analysis of different proverbs (more then 5000 makes it possible to draw valid conclusions about the dominating tendencies and assessments. We concentrated on proverbs connected with the gender issues. They reflect the social aspects of relationships between a man and a woman. The analysis was seriously hampered by the natural semantic richness of proverbs. Our article focuses on the inner form of proverbs. Our first obvious conclusion will be as follows: the gender factor does not play the leading role in the majority of the Bulgarian proverbs. We can see in some proverbs the reflection of the masculine mentality and the power of man, which in itself is not the dominant factor. The negative female stereotype exists alongside the male one. At the same time the female character does not always have negative connotations. Very often the feminine beauty, mind, positive housewife image and patience are in focus. In addition, the indisputable fact of the presence of the „female“ voice, in which sorrow and suffering dominate, and the female consciousness becomes apparent in the understanding of the world created by Bulgarian proverbs. They characterize her emotional side and decisiveness, as well as her expression of resistance. The above in-depth analysis allows us to make the conclusion about certain independence of women even in those past times which are reflected in the proverbs. Confirmation of our main conclusion can be found in some historical facts such as: a married woman

    The Bulgarian National Digital Seismological Network (BNDSN) consists of a National Data Center (NDC), 13 stations equipped with RefTek High Resolution Broadband Seismic Recorders - model DAS 130-01/3, 1 station equipped with Quanterra 680 and broadband sensors and accelerometers. Real-time data transfer from seismic stations to NDC is realized via Virtual Private Network of the Bulgarian Telecommunication Company. The communication interruptions don't cause any data loss at the NDC. The data are backed up in the field station recorder's 4Mb RAM memory and are retransmitted to the NDC immediately after the communication link is re-established. The recorders are equipped with 2 compact flash disks able to save more than 1 month long data. The data from the flash disks can be downloaded remotely using FTP. The data acquisition and processing hardware redundancy at the NDC is achieved by two clustered SUN servers and two Blade Workstations. To secure the acquisition, processing and data storage processes a three layer local network is designed at the NDC. Real-time data acquisition is performed using REFTEK's full duplex error-correction protocol RTPD. Data from the Quanterra recorder and foreign stations are fed into RTPD in real-time via SeisComP/SeedLink protocol. Using SeisComP/SeedLink software the NDC transfers real-time data to INGV-Roma, NEIC-USA, ORFEUS Data Center. Regional real-time data exchange with Romania, Macedonia, Serbia and Greece is established at the NDC also. Data processing is performed by the Seismic Network Data Processor (SNDP) software package running on the both Servers. SNDP includes subsystems: Real-time subsystem (RTS_SNDP) - for signal detection; evaluation of the signal parameters; phase identification and association; source estimation; Seismic analysis subsystem (SAS_SNDP) - for interactive data processing; Early warning subsystem (EWS_SNDP) - based on the first arrived P-phases.

  20. Bulgarian banking: looking for sustainability

    Directory of Open Access Journals (Sweden)

    Garabed Minassian

    2013-10-01

    Full Text Available In this work, we trace and analyze the emergence of the crisis in the Bulgarian banking system as well as the behavior of the central bank and other macroeconomic institutions. The average annual rate of growth in the net profits of the commercial banks for the period 2002-2008 amounted to 31.6%, which encouraged and accounted for the increase in credits. After 2008, the pendulum began to swing back as the difficulties in collecting loan repayments increased, the strain in financial balances tightened and assistance and support from the regulators were requested. The level of the financial and operating income was maintained primarily because of the high interest rates on the loans, but the structure of their distribution shifted substantially. Administrative costs and depreciation were nearly frozen up, and impairment and provisions grew at the expense of profit. This work shows that macroeconomic policies allowed the expansion of the lending boom and encouraged its irrational development. Poor operation and poor quality of the institutions not only allowed but also enabled direction of investments to financing of inefficient production structures. Underestimating the negative consequences shoring up a dysfunctional institutional environment is deemed a form of irrationality; however, not one of the immediate economic players acted to override the economic and political environment. The financial and economic crisis currently affecting the country has its roots in the deficiencies of the domestic macroeconomic policies, and therefore, the efforts toward overcoming these failures should be directed at improved domestic macroeconomic management.

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

    Directory of Open Access Journals (Sweden)

    Gianfranco Brusaporci

    2015-05-01

    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.

    Power consumption and power generation in Bulgaria are considered. Coal production is insufficient to supply all the expected demand. Hydroelectricity has suffered because of recent droughts and accounts for only 7% of capacity. The alternative is nuclear power and Bulgaria is committed to a programme of nuclear reactor building. By 1990 nuclear-generated electricity should make up 40% of the country's total requirement. There are plans to raise this to 60% by the year 2000. The reactors under construction or planned are discussed. Nuclear power is also being planned for district heating. Although Chernobyl has caused a move against nuclear power in the West the Bulgarians feel they have no choice but to extend its use. (U.K.)

    Childhood obesity is a serious health problem worldwide with a prevalence rising to epidemic proportions. Television viewing is suspected as an important contributor and along with food advertisements significantly influence children's unhealthy dietary habits, purchase requests and adiposity. To examine the exposure of Bulgarian children to television food advertising and to make a content analysis of the food/beverage advertisements during children's television programmes. 41.5 h of children's television programming on three national networks, were videotaped. All recorded food advertisements were evaluated to identify the marketing strategies used for the stimulation of children's purchase requests. Food/beverage advertisements accounted for 124 (33.4%) of all commercials, with 96.8% being for unhealthy foods. 57% of them were aimed specifically at children as the most advertised products were salty/sweetened snacks and cereals, sweets, soft drinks/carbohydrate juices and salty foods, with no fruit or vegetable commercials. Food advertisements used more themes of adventure, animation, music and gifts to attract children's attention, and gave information based on the product's taste, physical qualities, novelty, presence of premiums/prizes. Of all food/beverage advertisements, 27.4% contained health-related information about the products; three-quarters of the advertisements were shot with young normal-weight actors with a good/healthy appearance. Almost all recorded food advertisements do not support the Bulgarian dietary recommendations for healthy and balanced eating. More activities to reduce the unhealthy food promotion to children are mandatory as restrictions by type of advertised food, target group or limits on the advertisements' account and times shown, as well as parental/self-regulation.

    Studies of the environmental radiation background are important from several points of view. First, they permit to estimate the exposure of humans to natural radiation background as a function of different geographical and geophysical parameters. Second, such studies can give also relevant information concerning the consequences of human activities on the presence of ionizing radiation and its sources in the environment. Our both institutions have started since 2000 year common studies in the field of environmental radiation background and its variation with the locality considered. First we have decided to compare the measuring methods used. They were compared on the territory of the Institute of Nuclear Research and Nuclear Energy of the Bulgarian Academy of Sciences (INRNE BAS), particularly in the surroundings of IRT 2000 research reactor. Further, they were compared also at the monitoring station on the territory of INRNE BAS. Finally, the studies were enlarged to the Moussala Observatory of the Institute at Rila Mountains. Several measuring instruments were used to characterize external environmental radiation exposure: Environmental radiation dose rate meter NB 3201 developed in the Czech Republic with a plastic scintillator with small NaI-TL crystal used to compensate the energy dependence to low energy photons; MDU-Liulin semiconductor spectrometer with Si-diode as the sensitive element able to characterize the radiation with both low and high LET; Thermoluminescent detectors (TLD) CaSO 4 :Dy, powder of this TLD material was filled to an Al dose. Results obtained are presented, analysed and discussed. A good agreement of the results obtained was observed, also when compared to the results of other experimental groups. (authors)

    Full Text Available For the linguistic landscape analysis of private signs of Banat Bulgarians we chose two cemeteries, both of them multiethnic, since Banat Bulgarians in Serbia do not form a majority population in any village. The cemetery in Jaša Tomić/Modoš is religiously mixed, but the Catholic and Orthodox part are still divided. Banat Bulgarians in Konak village are buried in the Catholic cemetery; there is a separate Orthodox cemetery for the majority population. These two villages (Jaša Tomić and Konak were selected because they share a similar situation from the diachronic socio-linguistical point of view: apart for a brief time during World War II, the Bulgarian/Paulician language was hardly taught since the early 20th century; Bulgarian was used only in the family and the Catholic church (there are prayer books in Banat Bulgarian; there were many mixed marriages; there was no revival of language and culture As inscriptions on all existing Banat Bulgarian Cyrillic headstones are in Serbian and none of the cemeteries visited have inscriptions in Bulgarian, or rather in the Bulgarian Cyrillic, this indicates that the use and knowledge of standard Bulgarian is limited among the Banat Bulgarians. At the same time, the use of Banat Bulgarian in the Latin alphabet on a proportionally large number of headstones up to the end of the 20th century in the Serbian part of the Banat, and also actively today in Vinga in the Romanian part of Banat, indicates the great importance of the Banat Bulgarian language in preserving the identity of Banat Bulgarians.

    Full text: Introduction: In this paper own results of the radiation monitoring of the Black Sea coast - from village Shabla to village Resovo are presented. The study was carried out under a project funded by the BS ERA NET in FP7 of the European Commission, together with the project partners. Materials and Methods: Sampling was conducted in June 2012. 4 seawater samples (including depth of Varna Bay), 12 sand samples, 2 algae samples, 5 bottom sediments samples, 3 surface river water samples, 1 sea fish sample and 1 medical mud sample were examined. The samples were analyzed by gamma spectrometer for determination of the content technogenic and natural radionuclides and by radiochemical methods for defining the specific concentration of strontium- 90. A comparison between the specific activities of radionuclides in sea and river water, in the sands in sea bottom sediments in points and fractions, as well as in green and red algae. Results: The content of Cesium- 137 and Strontium -90 in the tested sea water ranged from 0.0041 (0.0007) to 0,0110 (0,0027) Bq/l and 0.00362 (0.00047) to 0,00409 (0,00049) Bq/l. The concentration of Cesium-137 in river water is ≤ 0,0012 Bq/l. The content of Potassium-40 in the sands is over a wide range from 4.9 (0.7) to 1152 (47) Bq/kg, a testament to their different origins. There is a difference in the contents of the radio-cesium into the upper and the lower fraction of the deep bottom sediment, and the various sampling points. It is clearly distinguished a selectivity of radio-cesium accumulation in red algae and they can be used for bio-indicator. Conclusion: The assessment of the radiological status of the Bulgarian Black Sea coast shows that with the exception of the beach in Vromos all investigated areas are safe from a radiological point of view. All studied coastal marine water as radiological indicators meet the quality standards set by Ordinance H-4/2012

  11. Some environmental aspects related to sulphur emissions during combustion of Bulgarian coals

    International Nuclear Information System (INIS)

    Vassileva, C.; Vassilev, S.

    2004-01-01

    The mechanism of S emissions and their capture during combustion of some Bulgarian coals (Maritza East, Maritza West, Sofia, Pernik, Bobov Dol, Balkan) was studied based on the phase-mineral transformations in the inorganic matter during gradual heating of these coals. It was found that: 1) the organic, elemental and sulphide S is released from coal at 200-700 0 C; 2) the volatile S is initially captured by intermediate Ca-, Mg-, K-, Na-, Fc-, and Ba-oxides (mainly from decomposed organic matter and carbonates) with formation of their sulphates at 200-1000 0 C; 3) the decomposition of original and newly-formed sulphates occurs at 800-1300 0 C and they are the major source of volatile SO 2 from stack emissions of thermoelectric power stations (TPSs). The described mechanism of S emissions and their capture indicates that the traditional pulverized combustion (1200-1600 0 C) of the high-sulphur Bulgarian coals in TPSs is inadequate from an environmental point of view and other alternatives should be applied. Some of them such as fluidized-bed combustion and selective blending of the coals are proposed

    Full Text Available After the outbreak of the First World War, when Bulgaria joined the Central Powers through the alliance with Germany, and Romania joined the Entente, the religious relations had a few special times. The defeat of the Romanian army in Dobrudgea and its occupation by the German – Bulgarian troops brought about a real exodus of the Romanian Orthodox clergy who took refuge especially to Moldova. The war ruined a few churches of Dobrudgea and destroyed the houses of the priests who had left their parishes. The issue of the priests fled from Dobrudgea was discussed within a Council met in Iasi in the summer of 1918, when the participants tried to find solutions for their return to their parishes. I personally examined the documents of this council found today in the Archives of the Metropolitanate of Moldova and Bucovina, because they reveal the deficiencies of the Romanian Orthodox Church in regard to the administrative organisation both in Dobrudgea and in the Quadrilateral. Our study approaches two major events occurred in the Bucharest occupied by the German-Bulgarian troops: the Te-Deum service celebrated in the honour of the royal family of Bulgaria in the Metropolitan Cathedral and the attempt to steal the Holy Relics of Pious Dimitrios Basarabov. The German administration has also been involved in the two events, because the Primate metropolitan Conon asked them to resolve these religious Romanian- Bulgarian conflicts. The documents which mention the two events can be found in the Archives of the Holy Synod of Bucharest and have a special significance because they represent an aspect less examined of the First World War and of the Romanian-Bulgarian relations. The theme of this study has never been approached so far by the Romanian theologians and historians, the research covering a gap in the study of the history of the First World War and of the Romanian- Bulgarian relations.

    2000-01-01

    Because of low-quality of the most of Bulgarian coal and more rigorous ecological restrictions for decreasing of greenhouse gases the fluidized bed technology is the most appropriate combustion technology. A study with a pilot plant aiming to establish the values of technological parameters in view to maintain stable process of fluidized bed combustion at the specific burning characteristics of the Bulgarian coal was carried out. Coal of different quality and particle size production of 'Marbas' LTD mines were used. Series of experiments with batches of strictly determined content were carried out at minimal, average and maximal load. The technological factors as: layer's aerodynamics, layer's height, fuel's quantity and quantity of inert material were changed at each batch. The ecological factors were optimized considering coal's quality, plant's parameters, limestone's dosing and layer's aerodynamics. A regressive model for optimization of technological and ecological factors was created. An average coefficient of performance was achieved, resp. 82.27 % at combustion of coal from mines 'Maritsa-West' and 90 % from mine 'Lev'. A coefficient of sulfur oxides' capture 70 % was obtained at coal with sulfur content 3.1-3.9 %. In conclusion the fluidized bed technology is very suitable for combustion's characteristics of the Bulgarian coal

  2. The Notion of the Foreign in Hungarian and Bulgarian Phraseologisms

    2017-12-01

    Full Text Available The confrontation between the native and the foreign is a problem that focuses research efforts on a number of humanities, e.g. cultural studies, anthropology, linguistics, ethnography, etc. The following report analyses the notion of the foreign, the other, the different, reflected in the phraseological wealth of the Hungarian and Bulgarian languages. The reviewed phrasemes concentrate the shock upon collision with the different or evaluation of the experience gained in the continuous communication with the other. The foreign is usually individualized by outlining and exaggerating some of its characteristics using parallels, oppositions, and metaphors. The negative attitudes and judgments prevail over the others: the fear of the collective “I” losing its own identity creates a negative attitude towards the foreign, distorted, or wrong notion of the other and the different. Many of the idioms reflect interethnic relations from times long gone, and so they are no longer a significant part of the active vocabulary of Hungarians and Bulgarians. Their analysis, however, is of great interest as they preserve the collective memory of the Hungarian and Bulgarian cultural communities and reveal their traditional notions and knowledge.

    2017-01-01

    Full Text Available This article aims to explore and analyze the essence and nature of the pedagogical thought in Bulgaria during the Bulgarian National Revival as a basis for educational reform. Objectivity requires pedagogical ideas to be considered in the context of overall socio-political and cultural life in the country on the one hand, and amid universal spiritual revival in Europe on the other. These tasks could be undertaken by a major international study, which is why we consider some of the questions highlighting this topic – the positive example of Europe on educational thought in the country presented by Bulgarian writers in the 18th century through the first half of the 19th century. The achievements of free European nations developing in all spheres of life were perceived by Bulgarian Renaissance writers as an incentive to overcome the age-old material and spiritual backwardness of the Bulgarians by the power of knowledge. In their activity they proceeded from a clearly motivated purpose: to contribute by educating citizens about spiritual awakening and rise of the Bulgarian nation. According to them, mass secular education in their native language was the road that would take the Bulgarians from their present slavery and provide them with material and spiritual well-being, like in other European nations. The need for secular books and secular schools to be taught in the mother tongue was one of the main ideas of Bulgarian writers during the Renaissance. Their mouthpieces were mainly clergymen, who perceived their role as national leaders and educators. Alongside the emerging secular intelligentsia, they actively contributed to the spiritual and cultural advancement of the Bulgarian nation and its integration into European civilization. An enlightened, free and independent Bulgaria was the ideal of our Renaissance leaders P. Hilendarski, G. S. Rakovski and Hr. Botev. While the revolutionary figures from the late 19th century thought that this could

    At one time large sand dune formations were widely distributed along the Bulgarian coast. However, due to increased urbanization in the coastal zone, the areas of total dune landscape has been constantly reduced. Dunes presently comprise only 10% of the entire 412 km long coastline of Bulgaria: they embrace a total length of 38.57 km and a total area of 8.78 km2 Important tasks in dune protection are identification of landscape changes for a certain period of time and accurate delineation of sand dune areas. The present research traces sand dune changes along the Bulgarian Black Sea coast over a 27 year period (1983-2010). This period includes also the time of expanded tourist boom and overbuilding of the coastal zone, and respectively presents the largest dune changes and reductions. Based on the landscape change analyst in GIS environment the study also aims to explore the importance of different natural and human factors in driving the observed dune alterations and destruction. To detect and assess dune changes during the last 3 decades, we used data for sand dunes derived from several sources at different time periods in order to compare changes in shoreline positions, dune contours and areas: i) Topographic maps in 1:5,000 scale from 1983; ii) Modern Very High Resolution orthophotographs from 2006 and 2010; iii) QuickBird Very High Resolution satellite images from 2009; iv) Statistical information for population and tourist infrastructure is also used to consider the influence of human pressure and hotel developments on the dune dynamics. In addition, for more detailed description and visualization of main dune types, digital photos have been taken at many parts of the Bulgarian coast. The study was performed in GIS environment. Based on the results obtained the dunes along the Bulgarian coast were divided into three main groups with relation to the general factors responsible for their alterations: i) Dunes that have decreased in result of shoreline retreat

    Full Text Available This article is a comparative study that attempts to highlight the similarities and differences between Bulgarian agrarianism and Romanian peasants during the Interwar period, the Second World War and period of transition towards the Leninist-Stalinist totalitarian regimes. The objectives of our approach are integrated within the boundaries of the main research directions and concrete levels, namely: the general context from the two countries, early agrarian/peasants’ movements, the political program, election results, the promotion of certain legislative measures, and the relationship with other political and institutional entities. Without trying to offer an exhaustive view or reveal new aspects in the strict sense of the term, our contribution confronts, in a coherent whole, a series of data and information on the basis of which one could make value judgments. These judgments might help to shape a global, comparative image. Among the main sources of the article we included the monographic works signed by Ioan Scurtu, Pamfil Șeicaru, Apostol Stan, Dimitrina Petrova, John D. Bell, R.J. Crampton, supplemented by data from several other publications (encyclopedias, syntheses etc.. One can identify several distinct stages within the period under review (1918-1947. The broad picture is that the Bulgarian agrarian group was more popular and better organized than its Romanian counterpart, but more inclined towards Leftism and authoritarianism, which led to its political isolation in 1923 and subsequent fragmentation, whilst the Romanian peasants’ movement managed, after 1924, to remain at the forefront of the political scene, showing an interest for dialogue and sometimes for compromise, first with The National Party, then with the authoritarian monarchy, but also with the Antonescu regime and, to a lesser extent, with the communist regime.

    Virtual observatory could be defined as a collection of integrated astronomical data archives and software tools that utilize computer networks to create an environment in which research can be conducted. Several countries have initiated national virtual observatory programs that combine existing databases from ground-based and orbiting observatories, scientific facility especially equipped to detect and record naturally occurring scientific phenomena. As a result, data from all the world's major observatories will be available to all users and to the public. This is significant not only because of the immense volume of astronomical data but also because the data on stars and galaxies has been compiled from observations in a variety of wavelengths-optical, radio, infrared, gamma ray, X-ray and more. In a virtual observatory environment, all of this data is integrated so that it can be synthesized and used in a given study. During the autumn of the 2001 (26.09.2001) six organizations from Europe put the establishment of the Astronomical Virtual Observatory (AVO)-ESO, ESA, Astrogrid, CDS, CNRS, Jodrell Bank (Dolensky et al., 2003). Its aims have been outlined as follows: - To provide comparative analysis of large sets of multiwavelength data; - To reuse data collected by a single source; - To provide uniform access to data; - To make data available to less-advantaged communities; - To be an educational tool. The Virtual observatory includes: - Tools that make it easy to locate and retrieve data from catalogues, archives, and databases worldwide; - Tools for data analysis, simulation, and visualization; - Tools to compare observations with results obtained from models, simulations and theory; - Interoperability: services that can be used regardless of the clients computing platform, operating system and software capabilities; - Access to data in near real-time, archived data and historical data; - Additional information - documentation, user-guides, reports

    Full Text Available The issue of assessment of absolute and comparative sustainability of major governing structures in agrarian and farming industries is among the most topical issues for researchers, farmers, investors, administrators, politicians, interests groups, and the public worldwide. Despite this issue, practically there are no assessments on the sustainability level of the major types of Bulgarian farming enterprises in the conditions of European Union Common Agricultural Policy implementation. This study applies a holistic framework and assesses the absolute and comparative sustainability of major governing structures in Bulgarian farming industry—unregistered holdings, sole traders, cooperatives, and companies of various types. In this paper, the method of the study is outlined, the inclusion of a novel “governance aspect” of sustainability is justified, and the overall characteristics of the surveyed farming enterprises are presented. Then, the integral, governance, economic, social, and environmental sustainability of the farming structures of different juridical types is assessed. Next, the structure of farming enterprises with different sustainability levels is analyzed. Finally, the conclusion from this study and the directions for further research and amelioration of sustainability assessments are presented.

    The present hydro energy system in Bulgaria has been constructed mainly in the period 1950-1965. The currently utilized hydro-power potential, only 33% of the estimated technical potential, includes 87 HPP operating in 1991. A complex assessment of the environmental impact of the hydro energy objects as well as a comparative analysis of all energy sources in Bulgaria is made in the framework of Bulgarian Case Study of the DECADES Inter-Agency Project. The main types of environmental impact related to HPP operation are presented in 7 specific categories: land requirements, changes in the landscape, hydrological changes, micro-climatic changes, geodynamic changes, risk from man-made activities; generation of new ecosystems. A technique of expertise in ball is proposed as a suitable quantitative approach for more precise assessment of impact on climate factors from different energy sources. 2 tabs., 5 refs

    Full Text Available The Serbian ethnomusicologist and music pedagogue Miodrag A. Vasiljević corresponded with colleagues from neighboring Bulgaria between 1934 and 1962. This exchange of letters went through three phases. The first phase was linked with his stay in Skopje until the breakout of World War II; during the second phase - in the course of the 1940's - he was active in the Department for Folk Music at Radio Belgrade and he founded his method of music teaching on traditional Serbian music; in the third phase (the 1950's and beginning of 1960's Vasiljević aimed at a closer cooperation with Bulgarian musicians. All the phases are characterized by his pronounced interest in the folk music heritage of Balkan peoples. At the beginning that interest was focused on popularizing art music that was based on folk music. Later, he enthusiastically carried out his reforms of music teaching in Serbia, as well as improvements of methods in Serbian ethnomusicology.

    Full Text Available The purpose of this study was to examine the structure of national identity among young adolescents of Bulgarian and Czech origin. University students (N=161 completed the Multigroup Ethnic Identity Measure-Revised (MEIM-R (Phinney & Ong, 2007, four measures of psychological well-being and a measure of salience of ethnicity. Factor analyses of data for the two national groups yielded a two-factor structure that corresponded to two theoretical approaches to ethnic identity, as hypothesised. Similar patterns in magnitude of loadings were observed across groups, indicating that the MEIM-R could be used as a global composite index of national identity. National identity was related positively to measures of psychological well-being such as mastery, self-esteem and optimism, and negatively to measure of loneliness. MEIM-R scores were also moderately correlated with salience (the importance of a person's own national background in his or her life, across national groups.

    Full Text Available ABSTRACT BACKGROUND: Bacterial vaginosis (BV is the most common cause of vaginal discharge in women of reproductive age. The purpose of this study was to determine the frequency of BV in Bulgarian pregnant and nonpregnant women from several age ranges and to compare three different laboratory methods for Gardnerella vaginalis detection in patents suffering from BV. METHODS: Between September 2011 and June 2012, 809 women of 16-40 years of age separated in two major groups: nonpregnant - 469 (355 with and 114 without symptoms and pregnant - 340 (213 and 127 respectively were enrolled for the study. The women underwent three different laboratory tests simultaneously: scoring of Gram staining of vaginal smear, culture, and polymerase chain reaction (PCR assay for G. vaginalis. RESULTS: The microscopic method detected high frequency of BV in symptomatic (57% whereas only a minority of asymptomatic subjects (14% were detected. G. vaginalisassociated BV was diagnosed in approximately equal proportions when evaluated with PCR and microscopic method for both pregnant and nonpregnant women. The comparative analysis of microscopic evaluation, culture and PCR assays demonstrated greater concurrence (about 90% between Gram staining and PCR detection for BV, than both methods compared to culture. The combination of microscopy and PCR turned out to be very reliable and repeatable for detecting G. vaginalis-associated BV. CONCLUSIONS: This is the first comparative investigation on the epidemiology of G. vaginalisassociated BV in Bulgaria. The established highest frequency in the young Bulgarian women (21-30 years is alarming and should be considered in prophylaxis and reproductive programmes.

    1983-01-01

    From information relating to numbers of various types of diagnostic medical X-ray procedures annually performed over the period 1962-1981 and mean radiation doses thereby delivered to various organs, estimates were derived of mean annual effective dose equivalents to the Bulgarian population; they were found to have risen from 0.5 msv per capita for 1962 to 1.35 msv per capita for 1981. Also, taking into account information on population age distributions, genetically and leukemogenically significant doses were calculated and found to have increased from 0.3 and 0.45 msv per capita for 1962 to 0.96 and 1.15 msv per capita for 1981, respectively. Analysis of collective gonad dose equivalents for 1981 indicated medical applications and diagnostic X-rays in particular to be responsible for the bulk radiation exposure in excess of background. As of 1981, the absolute level of risk incurred through radiological diagnosis was estimated at 240 lethal cases (146 fatal malignant tumors and leukoses, and 94 severe genetic effects). The death rate from malignancies for this period being of the order of 13.5 x 10 3 cases, the additional 146 cases constitute less than 1% of spontaneous deaths. (authors)

    2015-07-01

    The concept of "primacy" as introduced by Jefferson in 1939 in urban geography leads to the notion of "dominant city" also known as the primate city. Practically, the notion was extended by Sheppard in view of discussing some "hierarchy". The type of dominance is not universal nor any hierarchy reversal. Both can be time and sample dependent. Thus, as an example taking into consideration the existence of both pieces of the puzzle, we consider and discuss the Bulgarian urban system. It is also interesting to compare data on two groups of cities in different time intervals: (i) the whole Bulgaria city system which contains about 250 cities, - studied in the time interval between 2004 and 2011, and (ii) a system of 33 cities, - studied over the time interval 1887 till 2010. These latter cities are selected because the population was already over 10 000 inhabitants in 1946. It is shown that new additional indices are interestingly introduced in order to compensate defects in the Sheppard index. Numerical illustrations are illuminated through a "length ratio" measure, which allows to distinguish the (often) observed departures from the hyperbolic ranking seen by Jefferson.

    The objectives of this Energy & Environmental Research Center (EERC) project were to evaluate Bulgarian lignite performance under both fluid-bed combustion and gasification conditions and provide a recommendation as to which technology would be the most technically feasible for the particular feedstock and also identify any potential operating issues (such as bed agglomeration, etc.) that may limit the applicability of a potential coal conversion technology. Gasification tests were run at the EERC in the 100-400-kg/hr transport reactor development unit (TRDU) on a 50-tonne sample of lignite supplied by the Bulgarian Lignite Power Project. The quality of the test sample was inferior to any coal previously tested in this unit, containing 50% ash at 26.7% moisture and having a higher heating value of 5043 kJ/kg after partial drying in preparation for testing. The tentative conclusion reached on the basis of tests in the TRDU is that oxygen-blown gasification of this high-ash Bulgarian lignite sample using the Kellogg, Brown, and Root (KBR) transport gasifier technology would not provide a syngas suitable for directly firing a gas turbine. After correcting for test conditions specific to the pilot-scale TRDU, including an unavoidably high heat loss and nitrogen dilution by transport air, the best-case heating value for oxygen-blown operation was estimated to be 3316 kJ/m{sup 3} for a commercial KRB transport gasifier. This heating value is about 80% of the minimum required for firing a gas turbine. Removing 50% of the carbon dioxide from the syngas would increase the heating value to 4583 kJ/m{sup 3}, i.e., to about 110% of the minimum requirement, and 95% removal would provide a heating value of 7080 kJ/m{sup 3}. Supplemental firing of natural gas would also allow the integrated gasification combined cycle (IGCC) technology to be utilized without having to remove CO{sub 2}. If removal of all nitrogen from the input gas streams such as the coal transport air were

    Full Text Available Relations between the Serbs and the Bulgarians at the end of the 13th century has been a part of global international relations in the Balkans and in the Danube region. The Tatars (Mongols as the powerful warring people represent external factor that highly influenced those relations. They also made powerful impact on the Serbian and Bulgarian states of the time. The relations between the Serbs and the Bulgarians had not been at the time determined by their attitude toward the Byzantine Empire which was of the Serbian state, while Bulgaria went through tough period of disintegration of the central power. The internal affaires of those two states influenced their mutual relations. During the war with the Byzantine Empire, king Milutin tried to keep Bulgaria on his side, which is the reason why he became related by the marriage to the Bulgarian imperial family. However, strong involvement of Nogay made this alliance non-useful. After 1299 Serbia lost interest for Bulgaria, and behavior toward the queen Ana made two states enter the 14th century as the enemies. The close relations would be maintained with Vidin. In the frame of those relations Milutin's marriage and release of the Bulgarian princess Ana should be regarded, while Stefan's marriage had been motivated differently and happened around 1305/1306.

    Full Text Available Bulgarian Odonata database is analysed for the period of the last 10 years. All new entries are summarised in individual species graphs representing the trends in data compilations. Special attention is paid on the role of communities in this process with a single study case which is evident of how a small contribution could elucidate important new information on some underexplored areas. It is concluded that for the past 10 years mountain areas and large Bulgarian rivers have been understudied. These should be the priority target areas in the investigations undertaken in near future.

    Technogenic and natural radionuclide content in red macroalgae (Ceramium rubrum, Corallina officinalis and Callithamnion corymbosum) from the Bulgarian Black Sea coast, collected in the period 1992-2003, was studied by low-level gamma-spectrometry. The data show that the nuclide concentrations depend on macroalgae species and coast locations. The highest nuclide content was measured in Ceramium rubrum species. The 137 Cs mean value is 9.8 Bq/kg, 19.6 Bq/kg for 226 Ra and 17 Bq/kg for 210 Pb. The radionuclide pollution is considerably small due to the absence of nuclear facilities along the Bulgarian Black Sea coast. (author)

    Full Text Available A 40-year-old Caucasian, the otherwise healthy male patient, presented with 3-years history of a prominent tumor-like formation, located on his back, without subjective complaints. Initially, the lesion was 1-2 cm in size but gradually increased to a visible-pronounced tumor-like formation. No other dermatologic diseases, neither other known abnormalities were reported for the medical and family history.  Softly-elastic on palpation tumor-like formation was established in the left infrascapular area of the back, measuring 8/9 cm in diameter. The lesion was clinically suspected for lipoma or another soft-tissue tumour with benign nature, so the patient underwent planned surgical excision under local anaesthesia. A tumour was excited with deep elliptical excision and furthered for histological evaluation, while the wound edges were sutured with single cutaneous stitches. Additionally, a large black-colored tattoo of the Bulgarian historical noble Khan Krum was also observed within the clinical examination, covering almost the whole upper 1/3 part of the patient’s back Within the careful clinical observation of the tattoo, we noticed a fibroma-like lesion, affecting the noble’s right iris. Fibromas are common benign tumours in Caucasians, composed of fibrous or connective tissue. They can be seen in all organs from mesenchymal tissue, in varies size. Eyelids are often commonly affected in elderly. Although very commonly seen in every day dermatological practice, fibromas have been never reported, located in the iris. In the presented case, a small ʺiris-fibromaʺ, hidden within a black-colored tattoo was diagnosed in a patient with lipoma, as a sporadic clinical finding.

    1988-01-01

    A method was proposed for determination of the circulating blood volume (CBV) by means of in vivo labelled red blood cells, which was compared to the routine method with 51 Cr-sodium chromate. To the patients concecutively was given 1 g of potassium perchlorate (for blocking of the organs, which actively absorbed the perchnetate ion) and 500 mkg of tin pyrophosphate (Bulgarian kit) with subsequent labelling of the red blood cells with 99m Tc-pertechnate (1,8 - 3,7 MBq). The volume of the red blood cells, and hence also CBV, was measured with the use of a modified by the authors formula, in which correction for the individual effectiveness of the cell labelling was done. In comparison with the standard method for in vitro labelling of the red blood cells with 51 Cr sodium chromate, the method proposed gave an insignificant difference of 4,16%, but when compared to the commercial tin pyrophosphate (of the firm Mallinckrot - Holland), the Bulgarian kit displayed equivalent qualities. It was concluded that the method has a high accuracy and was easy for execution, cause a low radiation burden of the patient and is suitable for application in nuclear cardiology and radionuclide angiography

  19. Labour Migrations of Bulgarians from Ukraine to the European Union Today and Tomorrow: Factors and Forecasts

    2011-08-01

    Full Text Available Labour migrations from Ukraine to the European Union are closely connected with the issues of interrelations between EU metropolitan countries and their Diasporas in Ukraine. Labour migration developments in independent Ukraine after 1991 have been moving towards their intensification. Migration trends among the Bulgarian Diaspora of South-Western Ukraine gained specific characteristics in the period of the world economic crisis. The enlargement of the EU in 2004 and 2007 led to the transformations in the preferences and choice factors of labour migrants, representatives of the Bulgarian Diaspora, while choosing the destination country in the EU. As a metropolitan country, Bulgaria has focused its policy on attracting its Diaspora groups, seeing them as labour and demographic potential for further development. This point of view is justified in many respects, though metropolitan country efforts must also be directed to the support of the Diaspora and its social, psychological, cultural and linguistic features.

    2007-01-01

    Full Text Available This article investigates the performative relationship among folklore, the market, and the state through an analysis of the politics of Bulgarian wedding music. In the socialist period wedding music was condemned by the state and excluded from the category folk but was adored by thousands of fans as a counter-cultural manifestation. In the post-socialist period wedding music achieved recognition in the West but declined in popularity in Bulgarian as fusion music's, such as chalga (folk/pop, arose and as musicians faced challenges vis-à-vis capitalism. As the state withdrew and became weaker private companies with profit-making agendas arose. Although it inspired chalga, wedding music began to be seen in contrast to it, as folk music. Recently, fatigue with chalga and nationalistic ideologies are revitalizing wedding music.

    The objective of this paper is to check if the exchange rate in newly emerged, relatively thin foreign exchange markets, follows a random walk pattern. The findings of the current study cast doubts on random walk presence in Bulgarian exchange rates against major international currencies. It turns out that the series of daily returns are stationary but correlated and therefore can be modelled better by higher-order ARIMA processes than by random walk.

    Full Text Available Medicinal plants have been intensively studied as a source of antitumor compounds. Due to the beneficial climate conditions Bulgarian herbs have high pharmacological potential. Currently, the antitumor effect of the Bulgarian medicinal plant Tribulus terrestris L. on human cancer cell lines is not studied. The main active compounds of the plant are the steroid saponins.The present study aims to analyze the effect on cell viability and apoptotic activity of total extract and saponin fraction of Bulgarian Tribulus terrestris L. on human breast cancer (MCF7 and normal (MCF10A cell lines. Antitumor effect was established by МТТ cell viability assay and assessment of apoptotic potential was done through analysis of genomic integrity (DNA fragmentation assay and analysis of morphological cell changes (Fluorescence microscopy. The results showed that total extract of the herb has a marked dose-dependent inhibitory effect on viability of MCF7 cells (half maximal inhibitory concentration is 15 μg/ml. Cell viability of MCF10A was moderately decreased without visible dose-dependent effect. The saponin fraction has increased inhibitory effect on breast cancer cells compared to total extract. Morphological changes and DNA fragmentation were observed as markers for early and late apoptosis predominantly in tumor cells after treatment. Apoptotic processes were intensified with the increase of treatment duration.The obtained results are the first showing selective antitumor activity of Bulgarian Tribulus terrestris L. on human cancer cells in vitro. Apoptotic processes are involved in the antitumor mechanisms induced by the herb. This results give directions for future investigations concerning detailed assessment of its pharmacological potential.

    Full Text Available The Golden and Fibonacci geometry forms are symbols of beauty and harmony. The shapes and symbols in the national traditions are always a source of creative ideas. The paper presents textile designs on the base of creations from the Golden and Fibonacci geometry and Bulgarian national tradition. Fourteen textile design project are presented with the use of the Golden spiral in the Golden square, Fibonacci series tiling with equalitarian triangles named Fibonacci rose and the spiral square with four Golden spirals from the Golden and Fibonacci geometry, and the three turtles – symbols from Kolobar tradition in Bulgarian national culture. The forms from the Golden and Fibonacci geometry are used directly as ornaments, constructional elements for ornaments, or as frames for entered elements. The symbols from Kolobar tradition are used directly as ornaments. Every design is presented in suitable two, three or four color model. The used geometrical forms from the Golden geometry and the Bulgarian national tradition are the base for successful textile design using the mirror, radial and translated symmetry and the plain rhythms as result from their combinations. The design is more successful when the geometrical ornaments are combined with suitable colors according to the connections between colors and lines on the base of their meaning, the latest fashion trends, and national traditions.

    2004-01-01

    A PC-oriented Emergency Response System (ERS) is developed and works in National Institute of Meteorology and Hydrology with Bulgarian Academy of Science. The creation and the development of ERS was highly stimulated by the CEC/IAEA/WMO project ETEX (European Tracer EXperiment). ERS comprises of two main parts - operational and accidental ones, realized for both regions 'Europe' and 'Northern Hemisphere'. The operational part runs automatically. It consists of the following modules: selection of proper meteorological data (analyses and forecast) received via the Global Telecommunication System (GTS) of WMO; preparation of input meteorological files used by both trajectory and dispersion models (so called operational data base); completion of the respective meteorological archives, trajectory calculations for selected NPP in Europe and Northern Hemisphere; visualization of the results and putting the pictures in a specialized Web-site. The operational part runs every 12 hours, after new meteorological information is received. The accidental part is activated manually when a real radioactive releases in occurred or during emergency exercises. Two Bulgarian dispersion models - LED and EMAP are a core of the accidental part, LED (Lagrangean-Eulerian Diffusion) being a typical puff-model, wile EMAP (Eulerian Model for Air Pollution) is a 3-D dispersion model. The source input is specified by the user - Bulgarian emergency authorities, and the visualized output (pollution distribution maps) is sent back via fax and FTP. In the paper, the ERS overall structure and its modules are described and an ERS application in emergency management is shown. (authors)

    2013-01-01

    The 3-monochloro-1,2-propandiol (3-MCPD) levels in soy sauces which contained hydrolysed vegetable protein were evaluated for the Bulgarian market. For analysis of 3-MCPD, a gas chromatography-mass spectrometry (GC-MS) method was applied with a linear range of 0.03-2.00 μg mL⁻¹ and a limit of detection (LOD) of 2.3 μg kg⁻¹ and a limit of quantification (LOQ) of 3.4 μg kg⁻¹. At these levels, the standard deviation was 5.1%, with recoveries between 81% and 102%. The method was applied to the analysis of 21 samples of soy sauce from the Bulgarian market. Results ranged from 3.7 to 185.6 μg kg⁻¹. Soy sauces produced from hydrolysed soy protein contained higher levels of 3-MCPD than naturally fermented sauces. In 38.4% of samples of Bulgarian origin, the 3-MCPD content was above the EU limit of 20 μg kg⁻¹. In all analysed samples, 33.3% had a 3-MCPD content above the EU limit.

  11. Licensing of nuclear facilities according to the Bulgarian Act on the Safe Use of Nuclear Energy

    2004-01-01

    The new Bulgarian Act on the Safe Use of Nuclear Energy /Nuclear Act/ has replaced the former Act on the Use of Nuclear Energy for Peaceful Purposes. The new Nuclear Act covers the activities involving nuclear energy and sources of ionising radiation mainly by establishing a consistent licensing regime. About 13 regulations specifying the provisions of the Nuclear Act have been recently adopted by the Council of Ministers, the most important one being the Regulation on the Procedure for Issue of Licenses and Permits for the Safe Use of Nuclear Energy. The Chairman of the Nuclear Regulatory Agency (NRA) is authorised by the law to consider any application for issue of a license or a permit under the Bulgarian Nuclear Act. The procedure starts with an application, filed with the NRA, and continues about nine months. The final decision could be for issuing of the license or permit or a refusal for issuing the claimed document. The denial must be grounded and is subject to appeal. The Nuclear Act prescribes the conditions for issuing of two types of licensing documents (authorisations): licenses and permits. From a legal point of view the two types of licensing documents have one and the same nature - they are individual administrative acts according to the Bulgarian law. That is why there is no difference between them in terms of the issuing procedure. The difference between licenses and permits could be explained as follows: while a license is issued for reiterated activities, a permit is issued for non-reoccurring activities, this division being a specific feature of the Bulgarian Nuclear Act. In the field of nuclear facilities usage only one type of license is provided for by the Nuclear Act - a license for operation of a nuclear facility unit. For the rest of the activities issuing of permits is envisaged, those permits being in compliance with the main stages of the authorisation process formulated by the IAEA, following the step-by-step approach - siting, design

    Full Text Available Organic production of foods is strictly regulated industry, which is different from the private market-gardening. The organic foods make up 1-2% of global food selling. The European Union and Bulgarian government nowadays encourage the transition to the organic farming and they grant resources to the farmers and food producers, which turn to it. Presently, 90 % of the organic food produced in Bulgaria is exported to richer European states. Bulgarian organic food is basically fruits: nuts, herbs and spices, as organic plant oils, tobacco, vegetables. There is lamb and veal on the market, as organic jam and honey. .

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

    Full Text Available Object of the study is surface water bodies from category “rivers” according to Water Framework Directive 2000/60/ЕС. Surface water assessment is important for number of activities such as: water management in the country, making reports to international agencies, determining the change of the resources in the light of upcoming climate changes. The determination of water resources is based on information of hydrometric stations from the monitoring network system in the National Institute of Meteorology and Hydrology — Bulgarian Academy of Sciences (NIMH-BAS in which real ongoing and available water flows that are subject of management are registered. In the study a technology for surface water bodies in the Bulgarian basins of the lower Danube is applied which has been developed in the frame of cooperative project together with the Ministry of Environment and Water. This is absolutely true for the Bulgarian section of the Danube River basin which is expressed in big number and variety of hydrological homogeneous sections. The river flow is characterized with annual and inter-annual variability determined by climatic factors and anthropogenic influences. The main obtained results of the present hydrologic studies are the usage of transferred information from gauged to ungauged watersheds and the estimation of the surface water bodies’ resources using original regression relationships based on multiannual hydrological information from the NIMH-BAS monitoring network. The relationships delineate the hydrological homogeneous areas with similar conditions of flow formation. The estimated resources have significant usefulness for all State institutions managing the water in the Danube basin and have already been introduced in the operative and management practice.

    Bulgaria is rich in the remains of past human settlements and activity. For example, along northern part of the Bulgarian coast, numerous underwater and coastal archaeological sites from different periods have been discovered - Prehistory, Antiquity (ancient Greek, Hellenistic, Roman), Mediaeval (Early Byzantium, Bulgarian). The most significant of them are: Durankulak archaeological complex with the largest Prehistoric necropolis in the world, Prehistoric necropolis at the area of Lake Shablenska Tuzla, Antique settlements Caron Limen and Bizone, archeological reserve Yalata, Antique and Medieval castle at Cape Kaliakra etc. As, this north part of Bulgarian coast has a huge archaeological potential there is a ground for thinking that the remains of other periods as well as a brand new, previously unknown sites can be discovered in the near future. This does not exclude the probability of being randomly found individual objects that largely can be prevented from archaeological contexts. Therefore it is important that these archeological sites are protected properly and preserved for future generations. In Bulgaria such sites and monuments are legally protected under the Law of cultural heritage and managed by the Ministry of culture and local authorities. However, today most objects and sites, as part of common European historical and cultural heritage are posed to a variety of potential impacts and treats, both natural and human-induced. This study discusses the implications of natural factors, (such as climate change, extreme waves, erosion and shoreline changes) and human contributions (coastal infrastructures, tourism and insufficient management by decision-makers) to coastal and underwater cultural heritage along the north portion of Bulgarian coast. Major natural processes that seriously affect on coastal and maritime heritage environment are direct physical impact by global climate changes, sea level rise and caused increase of waves and storms, acceleration

    Pavlova, P.; Vasilev, G.

    2007-01-01

    Main sources of excessive background ionizing radiation exposure for the Bulgarian public are the following: medical radiation procedures; occupational radiation exposure; enhanced natural radiation exposure (uranium mining and milling, artificial fertilizers, non-radioactive sources of energy, building materials etc.); environmental technogenic radionuclide contamination from global fallouts (1950-1970) and Chernobyl accident depositions (1986-1996 and after). The green leafy vegetation, incl. forage plants used for feeding of farm animals (sheep and cows) as well as leafy vegetables (lettuce, dock, spinach, parsley etc.) are one of the main reservoirs of technogenic radionuclides. Bulgaria is situated in the middle northern latitude zone (40 north - 50 north) where the global radioactive fallout from nuclear experiments (1945-1962) were most intensive. Bulgaria is also one of the countries most affected by the Chernobyl NPP accident on 26 April 1986. Respectively, the Bulgarian population dose burden is high compared with the other European countries (excluding the population near the site, i.e. Ukraine, Russia and Byelorussian). Both the global and Chernobyl fallout (globally distributed) contaminated the green leafy vegetation with technogenic radionuclides of two groups: Short-lived, mainly Iodine-131; Long-lived, mainly Cesium-137 and partially Strontium- 90. The effects on the Bulgarian public from technogenic radionuclide contamination of green leafy vegetation were analyzed. The analyses show the following chain in motion of technogenic radionuclides (Iodine-131 and Cesium-137 are chosen as representative): 1) Iodine-131: (duration of transfer - less than 30 to 60 days since fallout); a) fallout - meadow grass - sheep and cows - milk and dairy products - person; b) fallout - leafy vegetables - person; 2) Cesium-137 (duration of transfer - several days) (based on Chernobyl experience); a) fallout - meadow grass - forage - sheep, cows, etc. - milk and dairy

    Full Text Available Bulgaria emerged as an independent state in the Berlin treaty, which was signed after the 1877-1878 Ottoman-Russian war. After this, the Bulgarian administration began an anti-Muslim massacre campaign, like the Russians did before.The main aim of this article is to investigate the pressure, violence and massacres against the Muslim-Turks, organised by the Bulgarian gangs and the official administration. It is also proposed that the emigration of the Muslim-Turkish population began after this policy of violence.

  2. Radiation related cancer risk after ionization radiation exposure to the Bulgarian population

    Average annual individual effective dose of natural radiation background (NRB) for the Bulgarian population is estimated to be 2.33 mSv.a -1 (from 1.60 to 3.06). NRB has been considered nearly constant in time, but during the 20th century the radiation above NRB has gradually increased. It was mainly caused by the medical X-ray and radionuclide diagnostics, radiation treatment, occupational radiation, global radioactive fallout, Chernobyl accident, exploitation of thermal power and nuclear power stations, etc. For the years 1950-2000 collective dose from NRB represents 965 000 man.Sv and radiation over NRB gives 1 042 800 man.Sv. Population risk following radiation exposure is estimated mainly on stochastic health effect by implementation of the so-called Linear non-threshold model (LNM) dose-effect. It postulates no dose threshold for radiation-induced health effects. Using different models, assumptions and assessments, authors have determined the contribution of lethal radiogenic cancer to Bulgarian spontaneous cancer rate to be from 3.7% to 20.6%. Numerous contradictions and concepts about the LNM still persist, because from statistical point of view, LNM can neither be proved nor rejected. (authors)

Hounds are referred to as hunting dogs that engage in loud pursuit of game along its trail. These dogs do not need to se the game in order to pursue it and begin to bark once they stumble upon game trail. First serious research along with zootechnical measurement was conducted in 1905, at which occasion three large groups of hounds that inhabit the Balkans were described. This undertaking provided a solid foundation for further research and standardization of certain hound breeds. Though a lot of field work and standardization efforts were undertaken since then, there are still groups of hounds not encompassed in previous research work that are well-spread on the field and frequently utilized as hunting companions. One of the variety among these non-standardized breeds are Bulgarian scent hound, which differ from described hound breeds by certain exterior characteristics. In this paper, processed and analyzed some of the basic exterior features of body and head of the Bulgarian Scent Hound. Measurements were performed in 21 males and 15 females of following parameters, the height at withers, back height, loin height, chest circumference, body length, head length, skull length, nozzle length, head width and nozzle width. The average height of males is 54.60 and female 51.73 cm. Head length of males, on average, was 23.95 cm and females 23, 53 cm.

    68 different types of Bulgarian wines were studied in accordance with 9 optical parameters as follows: color parameters in XYZ and SIE Lab color systems, lightness, Hue angle, chroma, fluorescence intensity and emission wavelength. The main objective of this research is using hierarchical cluster analysis to evaluate the similarity and the distance between examined different types of Bulgarian wines and their grouping based on physical parameters. We have found that wines are grouped in clusters on the base of the degree of identity between them. There are two main clusters each one with two subclusters. The first one contains white wines and Sira, the second contains red wines and rose. The results from cluster analysis are presented graphically by a dendrogram. The other statistical technique used is factor analysis performed by the Method of Principal Components (PCA). The aim is to reduce the large number of variables to a few factors by grouping the correlated variables into one factor and subdividing the noncorrelated variables into different factors. Moreover the factor analysis provided the possibility to determine the parameters with the greatest influence over the distribution of samples in different clusters. In our study after the rotation of the factors with Varimax method the parameters were combined into two factors, which explain about 80 % of the total variation. The first one explains the 61.49% and correlates with color characteristics, the second one explains 18.34% from the variation and correlates with the parameters connected with fluorescence spectroscopy.

    Radionuclides and toxic metals in Black Sea green, brown and red macroalgae were investigated using Low-level Gamma Spectroscopy and Atomic Absorption Spectrometry AAS (FAAS, ETAAS). All algae samples were collected along the whole Bulgarian coast during the period 1996 - 2004. The obtained data show that radionuclide and metal concentrations depend on the macrophytes type and are higher in red Ceramium species. Tendencies in the concentration pollutants variations during the studied period are examined and all data give information about different macrophytic species ability to accumulate certain elements from one and the same sampling location The possibilities to use Chlorophyta, Phaeophyta and Rhodophyta algae phylums as bioindicators in marine environment are investigated. All obtained results show that use of macroalgae reduces the need of complex studies on chemical speciation of aquatic contaminants and makes algae valuable indicators for the seawater quality assessment. Higher levels are obtained at the northern part of the Black Sea due to seawater current circulation, originating from Danube, Dnyeper and Dnester river outflow and also at the southern part of the coast. All data show that there is no serious contamination along the Bulgarian coast

    Full Text Available The objective of this study is to examine the Bulgarian youths' mobility towards Europe. The investigation was carried out with 570 Bulgarian students. The data are presented as a questionnaire consisting of five parts. The first one deals with the motivations and is based on the Reversal Theory - predicting eight motivational states. The second part is based on the 2PAP theoretical model structuring the attitudes around four factors: Push, Pull, Anti Push and Anti Pull. The third one falls back on the Big Five Personality Test measuring five personality dimensions. And the concluding two parts are designed to obtain information about the degree of attraction and the intentions for mobility to the 25 destination countries of the European Union (EU. This has led to the hypothesis that a model of mobility exists based on these three theoretical models, as well as on emotional factors like attraction-repulsion to the country referred to. The hypothesis that was strongly supported by the statistical processing of the data will broaden our understanding of the youth's mobility. The present research is a part of a longitudinal study of the mobility intentions among young people. The investigation is of great interest from an educational, political and social point of view

    Multimorbidity is a health issue with growing importance. During the last few decades the populations of most countries in the world have been ageing rapidly. Bulgaria is affected by the issue because of the high prevalence of ageing population in the country with multiple chronic conditions. The AIM of the present study was to validate the translated definition of multimorbidity from English into the Bulgarian language. The present study is part of an international project involving 8 national groups. We performed a forward and backward translation of the original English definition of multimorbidity using a Delphi consensus procedure. The physicians involved accepted the definition with a high percentage of agreement in the first round. The backward translation was accepted by the scientific committee using the Nominal group technique. Some of the GPs provided comments on the linguistic expressions which arose in order to improve understanding in Bulgarian. The remarks were not relevant to the content. The conclusion of the discussion, using a meta-ethnographic approach, was that the differences were acceptable and no further changes were required. A native version of the published English multimorbidity definition has been finalized. This definition is a prerequisite for better management of multimorbidity by clinicians, researchers and policy makers.

    Full Text Available The Serbian army was forced to retreat towards Metohija and Albania eventually due to the armed aggression and attacks from the north and east in October 1915 by the united forces of the German and Austro-Hungarian units against the Kingdom of Serbia. Together with the army, the monarch, executive and legislative branch, intellectuals and civilians also retreated, not wanting to fall in the hands of the incoming army formations of the Central Powers. Following the retreat of the government and army bodies, the territory of the Kingdom of Serbia found itself under the control of the enemy forces, which started the 3-year period of occupation. The subject of this paper are the texts written by the newspaper called Leskovački glasnik (Leskovac Messenger in the period between World War I and World War II, which dealt with the sufferings of the Serbian civilians in the Bulgarian occupied zone from 1915 to 1918. Special attention is paid to the Leskovački glasnik's reports about marking the anniversary of the Bulgarian terror and killings of Serbs, about opening and consecration of memorials, about the heroic deeds and the tragic destiny of the people in south Serbia.

    Full Text Available The agricultural sectors of the former centrally planned economies, including Bulgaria were in a state of economic crises in the period after socialist governments fell. The former system disappeared almost overnight while new market structures had not yet emerged. The outcome of this transition shocks was a sharp decline in both agricultural output and the sector's GDP in the early 1990s. Some countries of the Central and Eastern Europe (CEE recovered from this initial decline much faster. The principle reason for the difference appears to be the more resolute adherence of CEE governments to reform policies throughout their economies. The purpose of this study is to get more knowledge about the structure and possibilities of Bulgarian agriculture after the transition period and last but not least, about the effects of the EU CAP on the Bulgarian economy and farmers.That is why were made some interviews, and besides, it was carried out a questionnaire survey in order to get a picture about how farmers act in a new environment called the Common Agricultural Policy of EU. For collecting information, as well as confirming or rejecting the investigation hypotheses chi-square analysis was applied.

    Pinho, Micaela Moreira; Pinto Borges, Ana

    Activity was undertaken to develop a Prioritization Scoring Index for Portugal and Bulgaria that weights the importance given to ethical rationing principles that should guide decisions at the bedside. Data from two random samples of 355 Portuguese and 298 Bulgarian members of the public were collected from an online questionnaire. Questions asked about the level of importance given to specific issues related to patient's prioritization criteria. Responses were analyzed quantitatively with the SPSS. In the process of selecting the patient to treat, Portuguese and Bulgarian respondents seem unanimous in giving greater importance to (i) the treatment outcomes, (ii) the severity of illness, (iii) children, and (iv) patients' fragility. In general, Portuguese and Bulgarian respondents allocate more than 50% of the prioritization weight to equity considerations, approximately 35% to efficiency considerations, and 5% to lottery selection. Even so, Bulgarian respondents rate highly the equity and less the efficiency consideration than Portuguese respondents. Although the pursuit of efficiency seems to be valued by respondents, their major concern seems to be with the reduction of inequalities in health.

    Full Text Available The article showcases a large-scale study of the modern Bulgarian anthroponymic system conducted by the Applied Onomastics section of the Bulgarian Academy of Sciences Institute for the Bulgarian Language (IBL with the aim of revealing the current trends in the choice of personal names by the Bulgarians at the beginning of the 21st century. The study focuses on personal names of Bulgarians born in 2010 in the Sofia region, as extracted from the Unified System of Civil Registration and Administrative Services of the Population of the Republic of Bulgaria. The total number of births this year was 1,005, of which 51.5% were boys, 48.5% were girls. Statistical and linguistic analysis of names allowed to measure the popularity of both individual personal names and different name types. It shows the quantitative ratio between most commonly chosen names and those of a singular use in relation to the total number of anthroponyms in the corpus, and proves that the male names are more sustainable in terms of usage than female. The derivational and etymological analysis of personal names helped to identify the productive word-formation types of names and the so-called “unisex names,” to distinguish between the native Bulgarian and the borrowed foreign names, as well as to classify graphic and phonetic variants of the same anthroponym. A number of quantitative comparisons were made between certain categories of names, for example, between compound (two-stem personal names (such as Miroslav and simple names (such as Biser, showing the ratio of the two-component personal names (such as Anna-Maria to the rest of the anthroponyms. It was found that the Bulgarian anthroponymic system in the beginning of the 21st century is more open to the non-adapted foreign names (like Mishel, Nancy, shows wider usage of diminutive “unisex names” (Moni, Stephy, Toni, as well as the growing popularity of shortened forms used as official names (Alex, Boni, Pepi, and the

    Full Text Available The astrometric European Space Agency (ESA Gaia mission was launched in December 19, 2013. One of the tasks of the Gaia mission is production of an astrometric catalog of over one billion stars and more than 500000 extragalactic sources. The quasars (QSOs, as extragalactic sources and radio emitters, are active galactic nuclei objects (AGNs whose coordinates are well determined via Very Long Baseline Interferometry (VLBI technique and may reach sub-milliarcsecond accuracy. The QSOs are the defining sources of the quasi-inertial International Celestial Reference Frame (ICRF because of their core radio morphology, negligible proper motions (until sub-milliarcsecond per year, and apparent point-like nature. Compact AGNs, visible in optical domain, are useful for a direct link of the future Gaia optical reference frame with the most accurate radio one. Apart from the above mentioned activities, Gaia has other goals such as follow-up of transient objects. One of the most important Gaia's requirements for photometric alerts is a fast observation and reduction response, that is, submition of observations within 24 hours. For this reason we have developed a pipeline. In line with possibilities of our new telescope (D(cm/F(cm=60/600 at the Astronomical Station Vidojevica (ASV, of the Astronomical Observatory in Belgrade, we joined the Gaia-Follow-Up Network for Transients Objects (Gaia-FUN-TO for the photometric alerts. Moreover, in view of the cooperation with Bulgarian colleagues (in the frst place, SV, one of us (GD initiated a local mini-network of Serbian { Bulgarian telescopes useful for the Gaia-FUN-TO and other astronomical purposes. During the next year we expect a new 1.4 m telescope at ASV site. The speed of data processing (from observation to calibration server could be one day. Here, we present an overview of our activities in the Gaia-FUN-TO which includes establishing Serbian { Bulgarian mini-network (of five telescopes at three sites

    Objective:The aim of the present study was to assess therapeutical effect of modified Ovsynch and PRID estrus synchronization protocols in Bulgarian Murrah buffalo with inactive ovaries during the low-breeding season. Methods:The study was carried out in 46 Bulgarian Murrah buffaloes with small inactive ovaries established by two consecutive transrectal ultrasonographies on Day 40 and 50 postpartum. At the start of the therapy the buffaloes were randomly divided into three groups. Group I (n=18) was treated by PRID-based protocol;Group II (n=18) was treated by Ovsynch based protocol and Group III (control;n=10) was injected intramuscular with saline at the same days as in the first two groups and fertile bull was introduced after that. The animals in the different groups were submitted to ultrasound examination at day of artificial insemination or bull introduction. Ovulation was determined 7 days post insemination by ultrasound. The pregnancy diagnosis was done 30 days after insemination. Mean diameter of the largest follicles at the start of therapy and the day of AI was registered. In the hormonal treated buffaloes estrus clinical sings, ovulation rate and pregnancy rate after AI were determined. In the control group pregnancy rate after spontaneous estrus was established. The mean diameter of the largest follicles determined on Days 40 and 50 after calving was not over 9 mm for all buffaloes. Results:At day of AI the average diameters of the preo-vulatory follicles in PRID and Ovsynch treated buffaloes were significantly (P<0.01) greater than these on Day 0. The cases of a clear uterine mucus discharge during the induced estrus were significant more (P<0.05) for Group I (94.4%) than Group II (66.7%). The pregnancy rate after AI (56.6%and 38.8%) in PRID and Ovsynch program was significant higher (P<0.05) than pregnancy rate after spontaneous estrus (10%) in the control group. Conclusions:the treatment of buffalo ovarian inactivity could start on Day 50

    Full Text Available This paper is devoted to the history of the socialist movement in Bulgaria and, in particular, to the evolution of the Bulgarian Socialist Party, later called Communist Party. The reasons for the rise of the revolutionary movement that led to the anti-fascist uprising in 1923 and its inevitable end were discussed. The paper critically analyzes the policy of the party when it became a ruling one and its power became authoritarian, falling into the hands of its leader. The reasons for the failure of the Stalinist type of "communism" imposed in Bulgaria by external circumstances as a result of the Second World War were considered. The discrepancy between the theory of Marxism and the Party’s prac-tice is highlighted and theoretical and practical conclusions are made.

    Radionuclides and heavy metals were studied in green, brown and red Black Sea macroalgae by low-level gamma spectrometry and atomic absorption spectrometry. The samples were collected along the whole Bulgarian coast from 1996 to 2004. The levels have been depending on algae species, locations and year of sampling. The highest 137 Cs levels were found in red Ceramium rubrum species from all studied locations, while 226 Ra and 210 Pb were up to three orders of magnitude higher in Bryopsis plumosa. The data showed that the red algae species (Rhodophyta) accumulate more heavy metals than the other phyla (except for Fe whose values were higher in green algae). The data confirmed that algae are valuable indicators of the environmental contamination. The observed elevated levels were mainly due to Danube, Dnieper and Dnester inputs in the NW corner of the Black Sea

    Full Text Available Propolis has shown activity against pathogenic microorganisms that cause diseases in humans and animals. The ethanol (Et-Blg and acetone (Ket-Blg extracts from a Bulgarian propolis, with known chemical compositions, presented similar activity against tissue culture-derived amastigotes. The treatment of Trypanosoma cruzi-infected skeletal muscle cells with Et-Blg led to a decrease of infection and of the intracellular proliferation of amastigotes, while damage to the host cell was observed only at concentration 12.5 times higher than those affecting the parasite. Ultrastructural analysis of the effect of both extracts in epimastigotes revealed that the main targets were the mitochondrion and reservosomes. Et-Blg also affected the mitochondrion-kinetoplast complex in trypomastigotes, offering a potential target for chemotherapeutic agents.

    The presented paper considers some specific questions of the licensing process regarding the reconstruction of the Bulgarian IRT-2000 research reactor, which includes conversion to the low enriched fuel. This specificity has risen as a result of two facts. The design of the reactor reconstruction was made on the basis of the existing fresh 36% highly enriched fuel. But after finishing of the design process, this fresh highly enriched fuel was shipped back to Russia in the framework of the RERTR program. These facts have involved some changes in both - in the licensing and the design processes. Re-analysis of the neutronic and thermal-hydraulic calculations is required to be made on the base of the technical specifications of the new LEU fuel. To facilitate the licensing process the NRA has adopted regulatory acceptance criteria for approval of the reactor core design with LEU fuel. (author)

    Full Text Available Regulating documents of the Bulgarian Army considered norms for support classic combat operations and in fact Bulgarian Army has no planning methods to be used for planning of humanitarian operations. Solving this problem can be achieved through the use of planning factors. Planning factors are generally based on experience or data on the use of resources from previous operations. The participation of units of the Bulgarian Army in humanitarian operations have failed to bring to the accumulation of data needed to create a suitable planning factors. The purpose of the study is to develop a model by which to bring out planning factors in determining the the consumption of machinery, tableware, fuel, oils and lubricants with the participation of units from the Bulgarian Army in humanitarian operations.

  3. Cross-Border Landscape: Construction of Natural Heritage and Local Development at Bulgarian-Serbian Borderlands

    Full Text Available Normally nature is examined as a phenomenon which is subject to natural laws; it belongs to the field of natural sciences. In constructivist perspective the environment is subsumed under the symbolism of humans’ tradition and culture. From such point of view the very notion of nature is unthinkable without taking into account its existence and understanding in a specific social, economic and cultural context of definite time, space and society. In the proposed paper I proceed from this paradigm in examination of a definite natural landscape which, however, is divided by the political border. The research attention is focused on a region of Bulgarian-Serbian borderlands – the area where the Erma River flows. The river takes its sources in Serbia and though it is not very long, it is notable for passing the Bulgarian-Serbian border twice, and for its two remarkable gorges – the Gorge of Tran in Bulgaria and the Gorge of Poganovo in Serbia. During the socialist period this border region was under strong military and police control. The crossing of the border was formally impossible; the borderlands remained peripheral industrially undeveloped areas and were putted under strong depopulation. However, the lands on either side of the border preserved its pristine nature. During the last two decades the preserved natural landscape and certain nature objects have been turned into more important landmarks and included in the value scale of local communities as symbols and heritage. In result, the above mentioned gorges have become more important part of strategic priorities in the local policies of revival of these economically undeveloped borderlands in the Western Bulgaria and Eastern Serbia. Nowadays the local efforts are uniting through different joint cross-border projects and activities in the sphere of nature preservation and eco-tourism.

    The main radiation sources the Bulgarian population is exposed to, e.g. natural radiation background and manmade exposure such as occupational, medical, nuclear power engineering and the like, are analyzed. The study covers the period 1991-1994 but it also contains a number of retrospective assessments concerning the last few decades. It is prepared with a special reference to the forthcoming report of the United Nations Scientific Committee on the effect of atomic radiation scheduled for publication in 1998/1999. The Bulgarian population exposure presented as average annual effective collective doses amounts to 20240 mSv/a from natural background, 6400 mSv/a from x-ray diagnostics, 400 mSv/a from nuclear medicine, 17 mSv/a from occupational exposure (uranium mining excluded) etc. Total exposure in excess to background irradiation is about 40% of the background one

    The nearly 50-year-long history of researches, mining and processing and closure of uranium industry of researches, mining and processing and the closure of uranium industry sites in the country as well necessitate reassessment of the radiation exposure of the human population in the regions nearby such projects. Proceeding from the available data from expert examination reports the radiation exposure of the Bulgarian population in excess of the background as a result of mining and processing of uranium ores is analysed. The study covers about 135000 persons. The mean value of exposure above the background, attributable to the technologically increased background amounts to 3.04 mSv/a at effective background dose about 2.3 mSv/a. The collective effective dose is 410 mSv/a and represents about 5 per cent of the overall radiation exposure of the Bulgarian population

    The Bulgarian Emergency Response System (BERS) is being developed in the Bulgarian National Institute of Meteorology and Hydrology since 1994. BERS is based on numerical weather forecast meteorological information and a numerical long-range dispersion model accounting for the transport, dispersion, chemical and radioactive transformations of pollutants. In the present paper, the further development of this system for a mixture of radioactive gaseous and aerosol pollutants is described. The basic module for the BERS, the numerical dispersion model EMAP, is upgraded with a 'dose calculation block'. Two scenarios for hypothetical accidental atmospheric releases from two NPPs, one in Western, and the other in Eastern Europe, are numerically simulated. The effective doses from external irradiation, from air submersion and ground shinning, effective dose from inhalation and absorbed dose by thyroid gland formed by 37 different radionuclides, significant for the early stage of a nuclear accident, are calculated as dose fields for both case studies and discussed

    1990-01-01

    The doses received by the Bulgarian population as a result of the Chernobyl accident rule out the possibility for development of nonstochastic effects; under these irradiation conditions the health injuries can be manifested as stochastic effects. According to the basic prognostic equation of ICRP (Publications 27 and 45) the irradiation associated with the accident would be responsible for 441 cases of cancer with lethal outcome and of 816 cases of curable cancer during the next 50 years, as well as for 68 cases of severe hereditary injuries during the next two generations. This means an increment of the annual case fatality rate from cancer in this country by an average of 0.006% and of the morbidity by 0.02%. Taking into account the inaccuracy admitted in determining the mortality and morbility, the radiation induced cancerogenic effects will remain unprovable within the framework of a generation life duration. The same refers to the radiation-induced genetic effects as well: less than one case annually over a period of 100 years. The Bulgarian population as a whole will lose about 67.10 3 man-days annually for 50 years due to the induction of curable and lethal cancers and about 79.10 3 man-days because of severe hereditary defects. Brief discussion is presented on the expediency of epidemiologic studies and developing screening programs for assessing the sequelaes of the Chernobyl accident for the health of the Bulgarian population. 8 refs

    Full Text Available Experiencing historical time: Apocalypse and authoritarianism in inter-war Bulgarian existential philosophy This article deals with the sense of the pace of time as reflected in the works of Bulgarian philosophers from the “philosophy of life” school, and of other thinkers active in the humanities. It is shown that the feeling of “condensed” time among the authors of the inter-war period is inevitably associated with Biblical imagery – the “reduction” of time foresees the end of time. Several authors left a lasting mark on Bulgarian intellectual history due to their sensitivity to the sharp turns of the age, and their awareness of the intense “flow” of time. The most prominent among tchem were Spiridon Kazandjiev and Yanko Yanev, authors with right-wing political leanings. This article reveals how the end of time provoked in them not only distress and anxiety but also exhilaration at what lay ahead, as if it were the realisation of a longcherished dream.   Doświadczanie czasu historycznego. Apokalipsa i autorytaryzm w bułgarskiej filozofii egzystencjalnej okresu międzywojennego Niniejszy artykuł poświęcony jest doświadczeniu tempa czasu, odzwierciedlonemu w twórczości bułgarskich filozofów sytuujących się w nurcie „filozofii życia” w najszerszym ze znaczeń, jak również innych myślicieli. Zostaje w nim pokazane, jak poczucie czasu „skon­densowanego” u autorów okresu międzywojennego nieodzownie kojarzone jest z obrazami biblijnymi – czas „zredukowany” zapowiada zbliżający się koniec.

    The considered sublacustrine river valley is situated in the shelf zone of the Black Sea. It runs in parallel to the Bulgarian coast, was formed in the time period of the Younger Dryas (Preisinger et al., 2005), and features an inclination of about 0.5 m/km. An about 200 km long sediment wall separates the approximately 10 km broad river valley from the outside shelf zone. This wall was generated during the Older Dryas until the beginning of the Younger Dryas. Its shape was formed by transportation of water and sediment from the Strait of Kerch by a circulating rim current in the Black Sea and water as well as sediment flow of the Danube in direction to the Bosporus. New investigations of the sediments of this river valley were performed by utilizing a Sediment Echo Sounder (SES 2000). This Echo Sounder is a parametric sub-bottom profiler enabling a high resolution sub-bottom analyses. It is capable of penetrating sea beds up to more than 50 m of water depth. The received echo data are real-time processed. The signal amplitudes are valuated in context to a logarithmic scale and graphically visualized by means of a colorized echogram utilizing false colours ranging from red for a high to blue representing a low signal (W.-D. Heinitz et al., 1998). The highest signal (red) is given by the acoustic impedance of the boundary between sea water and river sediment. The echograms of the river valley depict spatially isolated (red) high-signal peaks, which are periodically repeated in vertical direction between the sediment surface and the bottom of the valley. The number of these high-signal parts increase with an increasing valley depth. Studying of the distribution of these peaks allows to draw conclusions regarding the content and composition of the sediment. This prediction of the sediment composition obtained by means of the SES 2000 was successfully verified by analyzing a gravity core taken near Nos Maslen (at 44 m water depth) with a particular focus on the water

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

  16. Contribution to atmospheric methane by natural seepages on the Bulgarian continental shelf

    This paper provides an estimation of the atmospheric methane flux from Bulgarian Black Sea continental shelf. Potential gas source rocks include Holocene gas-charged sediments, Quaternary peats and sapropels, and deep-lying Palaeocene and Neogene clays, Cretaceous coals, and other sediments of late Jurassic to early Cretaceous age. These cover almost the whole continental shelf and slope and, together with irregularly developed seal rocks and widespread active and conducting faults, provide good conditions for upward gas migration. A total of 5 100 line kilometers of shallow seismic (boomer) and echo-sounder records acquired during the Institute of Oceanology's regional surveys, and several detailed side-scan sonar lines, have been reviewed for water column targets. Four hundred and eighty-two targets were assigned as gas seepage plumes. It is estimated that a total of 19,735 individual seeps exists on the open shelf. The number of seeps in coastal waters was estimated to be 6020; this is based on available public-domain data, specific research, and results of a specially made questionnaire which was distributed to a range of 'seamen'. More than 150 measurements of the seabed flux rates were made in the 'Golden sands' and 'Zelenka' seepage areas between 1976 and 1991. Indirect estimations of flux rates from video and photo materials, and a review of published data have also been undertaken. Based on these data, three types of seepages were identified as the most representative of Bulgarian coastal waters. These have flux rates of 0.4, 1.8, and 3.51/min. The contribution to atmospheric methane is calculated by multiplying the flux rates with the number of seepages, and entering corrections for methane concentration and the survival of gas bubbles as they ascend through seawater of the corresponding water depth. The estimation indicates that between 45,100,000 (0.03 Tg) and 210,650,000 m{sup 3} (0. 15 Tg) methane yr{sup -1} come

    Full Text Available The paper presents results of analysis of 96 macrozoobenthic samples, collected on a seasonal basis in Bourgas Bay and in open-sea areas offshore Cape Emine (Bulgarian Black Sea in 1996 and 1998. In total 96 taxa were established, distributed in four groups: Polychaeta, Mollusca, Crustacea and “Diversa”. The average density of populations was 1756 ind.m-2 with a predominating abundance of Polychaeta species. The average biomass estimated was 183.02 g.m-2, formed mainly by representatives of Mollusca. The latter species were measured together with the shells, which appraised their individual weights. Seven of the species found had a coefficient of constancy more than 50%. These were the most adapted species to the environmental conditions of the investigated areas. The quantitative and qualitative assessments in this study demonstrate an increasing tendency in the parameters obtained (density, biomass, species diversity in comparison with previous investigations in the early 1990-s, when intensive anthropogenic influence was widely perceived to misbalance the Black Sea ecosystem. The method of Warwick (1986 applied to characterize the water quality of the studied areas allowed us to define them as rather clean or moderately polluted aquatories.

    X-ray and radionuclide application in medical diagnosing is the major sources of Bulgarian population exposure to ionizing radiations exceeding the radiation background. The number of X-ray examination on a nationwide scale shows an increase from 1600 thousand annually in 1950 to 10300 thousand in 1980 and decreases to about 4700 thousand annually for the period 1992-1993. The frequency for the above mentioned time intervals varies in the range 0.22 to 1.17 examinations per capita annually and decreases to 0.56. The roentgenoscopy to roentgenography ratio varies from 2.5:1 to 0.9:1 (1975) and increases to 2.0:1 (1993). The number of radioisotope examinations increased from 34 thousand in 1970 to 170 thousand annually in 1985 and decreased to about thousand annually in 1992-1993 with a number of studies per capita varying from 0.004 to 0.020 and decreasing to 0.010. In 1993 the annual collective effective dose due to X-ray diagnostics amounts to about 7000 man-Sv/a which exceeds the radiation background exposure by 76%. Radioisotope diagnostics in the period reviewed accounted for nearly 700 man-Sv/a with an exposure exceeding the radiation background by 7.7%. The major problems relating to patient protection and benefit/risk ratio improvement are discussed. (author)

    In the frame of the NIMH at BAS investigations of the Black sea radioactivity were initiated in 1978 with a development of a monitoring campaign. Samples of sea waters, sediments and algae were collected from several sampling sites along the coastal zone and measured by gamma-spectrometry. Results on gamma-emitting radio-nuclide's measurements in the Black sea coastal waters were published in the 80's. After the Chernobyl accident during the period between 1986-1989 seasonal-fields sampling campaigns were organised and radioactivity of algae and bottom sediments was estimated. Harmonized sampling strategies, analytical procedures and related data information exchange for radioactivity of seawater, sediment and biota in coastal areas of Black Sea countries were developed under the IAEA TCP Black Sea Project. The present work reports results of the monitoring programme of the NIMH of Bulgaria developed in the frame of the IAEA projects for the Black Sea basin. From 1993 to 2005 regular seasonal sampling was performed in 5 sampling sites along the Bulgarian Black Sea shore. Results of the dissolved '1'3'7Cs concentrations in sea water, sand, algae, and fish samples are discussed. The data for the different radio-isotopes measured in algae, fish and sea sediment samples are given in comparison with other investigations. A complex assessment of Cs-137 concentrations as important tracer and indicator of the marine processes is made on a long-term basis. (author)

    Full Text Available Abstract. The aim of this paper is to establish the biodiversity status of the macrozoobenthos in some protected marine areas (NATURA 2000 along the Bulgarian Black Sea coast. The observation stations in the period 2010-2012 were within the frames of the following habitats: 1160 – Large shallow inlets and bays; 1110 – Sandbanks, slightly covered by seawater and Sublittoral mussel banks on sediment. In general, the data shows steady state compared to the 1980s, except for the area near Kamchia River, characterized by low biodiversity due to water pollution from the river inflow (with contaminants from agricultural and industrial sources in the upper river stream and less salinity leading to marine mussel species reduction. In the border area, near the Emona zone, the black mussel catches varied between 160-600 kg in 2005, while only single specimens were detected in 2013. In the same field, the yield of Rapana venosa was within the limits of 5-40 kg in 2005 and between 80-160 kg in 2013. The established variability showed a dynamic balance between Mytilus galloprovicialis and Rapana venosa that pose a challenge for future stock of the black mussel and point the need of regular monitoring.

    Full Text Available The Ukrainian crisis has been a test for the alignment of Romania and Bulgaria with the EU on the background of the Union’s new foreign policy instruments as redesigned by the Lisbon Treaty. This paper aims to present the positions of Bulgaria and Romania towards the events of 2013-2015 in Ukraine. Our research target is to identify the driving forces that shaped these positions, to analyse and describe the main foreign policy goals and actions of Bucharest and Sofia regarding the Russian-Ukrainian conflict, and to compare the attitude of these two countries toward the Ukrainian crisis. The paper analyses first the Romanian and the Bulgarian perspectives on the dramatic events in Ukraine in the first half of 2014. The positions of the two countries are further placed in the wider international context of the Ukrainian crisis – the UN resolutions, the EU sanctions against Russia, NATO activities, and the security in the Black Sea region. In the third part Romania and Bulgaria are viewed as a “playground” for the competing narratives and propaganda in regards to the Russian-Ukrainian conflict. We also examine the economic impact of the crisis on the two Balkan countries, as well as the efforts of both Bucharest and Sofia to protect their respective minorities in Ukraine. In conclusion, we summarize the results of our research and explain how the Ukrainian crisis has reshaped the foreign policy debates in Romania and Bulgaria.

    Full Text Available Polycystic ovarian syndrome (PCOS is one of the most common endocrine disturbances in women of reproductive age. Besides its well-known effects on reproductive health, it is also linked to increased cardiovascular risk in later life. The aim of this study is to investigate some classical cardiovascular risk factors in a crossectional study of Bulgarian women with PCOS and/or obesity. We performed a retrospective medical chart review of 375 women from an university endocrine clinic. We found significant differences in the indices of carbohydrate metabolism, blood pressure, lipid profile, rate of liver steatosis, and the levels liver enzymes and hematological results between the lean and obese PCOS women. Obese women without PCOS did not show significantly different results in their OGGT form obese PCOS women. Waist-to-stature-ratio (WSR correlated better with the baseline IRI levels and lipid profile than waist-to-hip-ratio (WHR that makes it a better marker for unfavorable metabolic profile.

    Full Text Available The paper analyzes the credit risk disclosure in the annual financial statements of Bulgarian banks for 2015 and 2016. Banks are ranked according to the level of credit risk disclosure, in accordance with the requirements of international accounting regulations and in relation to financial and regulatory ratios linked to capital adequacy. As a result of the conducted empirical study, it is concluded that banks' management is not particularly inclined to make full disclosures and actively to declare internal qualitative and quantitative information. However, the level of disclosure of credit risk for banks in Bulgaria is high. Banks with a low degree of capital adequacy tend to make a more complete disclosure of credit risk, and vice versa. There were no indications of a link between the size of the bank assets, the existence of the bank as a public company and the disclosure of credit risk. We believe that, in the context of increased competition, the disclosure of credit risk from a formal requirement may become one of the many tools to stabilize the position of certain banks and create a positive image of the bank for public information users.

    2017-01-01

    Full Text Available A simple and cost-effective method was applied for the synthesis of zeolite composites utilising wet bottom boiler slag from the Bulgarian coal-fired thermal power plant “Sviloza”, near the town of Svishtov. The method consisted of a prolonged alkali treatment at room temperature of this waste. Experimental techniques, such as scanning electron microscopy, energy-dispersive X-ray and X-ray diffraction analyses, are employed to characterize the initial slag and the final products with respect to their morphology, and elemental and mineral compositions. The composites synthesized in this way contained two Na-type zeolite phases: zeolite X (type FAU and zeolite Linde F (type EDI. The zeolited products and the starting slag were tested as adsorbents for a textile dye (Malachite Green from aqueous solutions. In comparison with the initial slag, the zeolite composite possessed substantially better adsorption properties: it almost completely adsorbs the dye in much shorter times. The results of this investigations revealed a new, easy and low cost route for recycling boiler slag into a material with good adsorption characteristics, which could find different applications, e.g., for purifying polluted waters, including those from the textile industry.

    Full Text Available The territorial system overlapping cross-border areas shapes a particularly dynamic and complex functional area. This paper synthesises several research outcomes regarding the social and environmental dysfunctions and opportunities defining the marginal territories that were emphasised during the ‘Analysis and diagnosis of the current situation in the cross-border area’, a phase of the project ‘Common Strategy of Sustainable Territorial Development of the Romanian-Bulgarian Cross-Border Area’ (SPATIAL. The main indicators concerning the population structure and movement highlight a series of problematic aspects within the cross-border area: population decline, significant rural population concentration on the Romanian side, demographic ageing, increase in the age dependency ratio, and a negative natural growth and migration rate. The analysis also indicates areas of socio-demographic potential that are marked by population growth, a significant young population presence that is convergent with an important share of active population. In this perspective, the spatial analysis also focused on identifying natural drivers affecting development and restrictive factors, on the environmental quality evaluation, as well as on establishing areas exposed to natural and technological risks. Therefore, delineating and analysing components underlying social and environmental processes were intended to determine those issues and opportunities considered to influence the evolution of this potentially functional area.

    Full Text Available The diagnosis of deviations in quality of yogurt is performed by approved methods set out in the Bulgarian national standard (BNS and its adjacent regulations. The basic method of evaluation of the microbiological quality of the product is the microscopic. The method is subjective and requires significant processing time of the samples. The precision of diagnosis is not high and depends on the qualifications of the expert. The systems for pattern recognition in the most natural way interpret this specific expert activity. The aim of this report is to assess the possibility of application of a method of processing and image analysis for determination of the microbiological quality of yogurt. Selected method is template matching. A comparative analysis is made of the methods for template matching. The comparative analysis of available algorithms showed that the known ones have certain disadvantages associated with their rapid-action, the use of simplified procedures, they are sensitive to rotation of the object in the template. It is developed algorithm that complement these known and overcome some of their disadvantages.

    Bulgaria is a country which is located in the Eastern Europe. A drinking water sources on the North part of Bulgarian Black Sea coast have different radiological indices. The sources of drinking water can be lakes, rivers, wells, dam lakes and so on. Property estimation of the contents of Uranium (Ur), Radium (Ra 226), and total Beta activity, shows that concentrations of investigated parameters vary around TDI (tolerable daily intake). To Uranium for example the TDI yields a guideline value are 2 μg/litre if a 60 kg adult consuming 2 litres of drinking water per day and the provisional guideline value of Uranium which shows the health significance in drinking waters is 0.002 mg/1. The situation with the full Beta activity and Radium concentrations is the same. All these qualitative and quantitative indices are close to the provisional guideline values, but in some cases it is higher than the limit concentrations. The full Beta activity is measured in Becquerel per litre and values are around 0.193+7-20% Bq/1. The Radium concentration takes the dimensions of Bq/1 and it is about 0.009 Bq/l. No matter of the source of drinking water, contents of radiological indices is a very important element of the health care control

The content of potentially essential and toxic elements: chromium, manganese, iron, copper, nickel, cadmium and arsenic in Bulgarian fruits such as aronia, morello, cherry, raspberry, nectarine peach, apple type „akane” and pear type „early gold” were investigated. By using the ICP-MS we found that -1 -1 -1 raspberry has the highest content of iron (4635.9 ± 53.2 μg kg , manganese (5690.9 ± 31.7 μg kg and chromium (150.2 ± 2.5 μg kg , while the richest in -1 copper is the nectarine (887.5 ± 31.19 μg kg . The content of toxic elements (nickel, cadmium and arsenic is in amount significantly below the permissible standards. Single ANOVA and subsequent Dunkan's test were used to define the fruit and to estimate the significance of chemical elements. The test for multidirectional comparisons indicated that for five of the investigated seven elements: iron, copper, nickel, cadmium, and arsenic the fruits are statistically distinguishable According to hierarchical cluster analysis the fruits are into one cluster.

The growth and acidifying activity of the starter culture bacteria Streptococcus thermophilus 13a and Lactobacillus delbrueckii subsp. bulgaricus 2-11 were monitored during milk fermentation and over 15 days of yogurt storage at 4 degrees C. Fortifying milk with iron did not affect significantly the growth of the starter culture during manufacture and storage of yogurt. Counts of yogurt bacteria at the end of fermentation of iron-fortified milks were between 2.1 x 10(10) and 4.6 x 10(10) CFU ml(-1), which were not significantly different from numbers in unfortified yogurts. In all batches of yogurt, the viable cell counts of S. thermophilus 13a were approximately three times higher than those of L. delbrueckii subsp. bulgaricus 2-11. Greater decrease in viable cell count over 15 days of storage was observed for S. thermophilus 13a compared to L. delbrueckii subsp. bulgaricus 2-11. Intensive accumulation of lactic acid was observed during incubation of milk and all batches reached pH 4.5 +/- 0.1 after 3.0 h. At the end of fermentation process, lactic acid concentrations in iron-fortified yogurts were between 6.9 +/- 0.4 and 7.3 +/- 0.5 g l(-1). The acidifying activity of starter culture bacteria in the control and iron-fortified milks was similar. There was no increase in oxidized, metallic and bitter off-flavors in iron-fortified yogurts compared to the control. Iron-fortified yogurts did not differ significantly in their sensorial, chemical and microbiological characteristics with unfortified yogurt, suggesting that yogurt is a suitable vehicle for iron fortification and that the ferrous lactate is an appropriate iron source for yogurt fortification.

    The severe accident in Fukushima Nuclear Power Plant (NPP) in 2011 causes serious anxiety among the population not only in the neighbourhood, but even in countries quite far from the accident location. On Friday, March 11, 2011, Japan experienced a natural disaster of inconceivable dimensions. At 2.46p.m. local time, a gigantic earthquake with the epicentre approx. 150 km east of the city of Sendai in the Pacific Ocean also shook the coastal region nearby. The seismic event was triggered by abrupt tectonic plate shifts some 20 to 30 km below sea level. The seaquake had an intensity of 9.0 on the logarithmic scale, which is O.S points above the severest earthquake of 8.2 so far registered in Japan. This unexpectedly high energy release caused a tsunami wave of a maximum height of 23 m which flooded the coastal region approximately one hour later, causing a large number of human casualties and extreme devastation of towns and villages, infrastructure, and the environment. Four nuclear power plants are located in the area directly affected by the disaster: Onagawa, Fukushima Daiichi, Fukushima Daini, and Toman. The site of Fukushima Daiichi was hit most severely. Bulgarian ERS (BERSJ was upgraded to be able to simulate the dispersion of nuclear materials from Fukushima Daiichi NPP, results presented in the specialised web-site of the system. In addition BERS took part in the respective ENSEMBLE exercises. Short BERS description as well as its results and comparisons with measurements and other model results are the object of this work.

    Full Text Available The aim of this study was to analyse the correlation between cases of human papillomavirus (HPV+/− infection of the uterine cervix revealed through HPV typing and cytological results from Papanicolaou (Pap-stained cervical smears. Cervical smears of 421 Bulgarian women attending routine gynaecological examinations during the three-year study period were stained by the Pap technique and classified by the Bethesda system. GenoFlow HPV Array Test Kit was used to analyse the HPV status in the collected cervical samples. The results showed that, of the 421 women, 177 (42% were HPV(+ and 244 (58% were HPV(−; 334 (79.3% Pap smears were with normal morphology and 87 (20.7% had high/low grade squamous intraepithelial lesion (LSIL/HSIL changes. Of the 87 women with LSIL/HSIL changes, 54% (47/87 were HPV(− and 46% (40/87 were HPV(+. There was no statistically significant correlation between the HPV(+ status and the cytological LSIL/HSIL findings (P > 0.05. Koilocytes were found in 30.4% (128/421 of the samples. Of the 128 women with koilocytosis, 59.4% (76/128 were HPV(− and 40.6% (52/128 were HPV(+. There was no significant correlation (P > 0.05 between the presence of koilocytes in cervical smears and HPV infection. Our results suggest that HPV infection is frequent even in women with negative Pap-smear results, and polymerase chain reaction seems to be the only reliable test to diagnose this infection. However, the results from this study cannot be considered to fully support the replacement of cytology and colposcopy examination in cervical cancer screening with HPV genotyping tests only.

    Patient safety (PS) is one of the essential elements of health care quality and a priority of healthcare systems in most countries. Thus the creation of validated instruments and the implementation of systems that measure patient safety are considered to be of great importance worldwide. The present paper aims to illustrate the process of linguistic validation, cross-cultural verification and adaptation of the Bulgarian version of the Hospital Survey on Patient Safety Culture (B-HSOPSC) and its test-retest reliability. The study design is cross-sectional. The HSOPSC questionnaire consists of 42 questions, grouped in 12 different subscales that measure patient safety culture. Internal con-sistency was assessed using Cronbach's alpha. The Wilcoxon signed-rank test and the split-half method were used; the Spear-man-Brown coefficient was calculated. The overall Cronbach's alpha for B-HSOPSC is 0.918. Subscales 7 Staffing and 12 Overall perceptions of safety had the lowest coefficients. The high reliability of the instrument was confirmed by the Split-half method (0.97) and ICC-coefficient (0.95). The lowest values of Spearmen-Broun coefficients were found in items A13 and A14. The study offers an analysis of the results of the linguistic validation of the B-HSOPSC and its test-retest reliability. The psychometric characteristics of the questions revealed good validity and reliability, except two questions. In the future, the instrument will be administered to the target population in the main study so that the psychometric properties of the instrument can be verified.

    Full Text Available The coastal lakes are rich sources of biostratigraphic information that is very useful in palaeoecological reconstructions of climate changes and human impact on the natural vegetation. This information is of great importance for the archaeological descriptions of submerged praehistorical settlements found in the northern Bulgarian Black sea area. There are 4 archaeological sites in this area that have been palynologically studied for the last 30 years: the Durankulak Lake, the Shabla-Ezeretz Lake system, the Lake Bolata, as well as the Varna-Beloslav Lake system. Because of the lack of AMS radiocarbon dates for these sites, it was not possible to correlate adequately all palaeoenvironmental results with the available archaeological chronology.Aimed to receive additional information on the Holocene vegetation dynamics and lake level changes, as well as on the anthropogenic impact during the Late Eneolithic and Early Bronze Age, the high-resolution spore-pollen analysis of AMS dated laminated sediments from a new Core 3 – Varna Lake was combined with analyses of dinoflagellate cysts, acritarchs, and other non-pollen palynomorphs.The location of the core is close to several sites of submerged praehistorical settlements and the Varna Late Eneolithic (Chalcolithic Necropolis, which is famous with the oldest hand-made gold treasure in the Worlds, and permits the palaeoenvironmental correlations of obtained results with available archaeological and geochronological data. The core is 995 cm long, but its palynologically investigated length is 870 cm. It contains dark grey clay and laminated sediments (varves. Seven samples of sediments were submitted for radiocarbon dating to the National Ocean Sciences Accelerator Mass Spectrometry (NOSAMS Facility of Woods Hole Oceanographic Institution (WHOI. The dates have been calibrated using the program CALIB version 6.1.0 of using the IntCal09 curve. An Age Model for the sedimentation rate was created by the

    the objective of this cross-sectional research was to outline the different somatotypes and the trends in the changes of the three basic components (endomorphy, mesomorphy and ectomorphy) among the middle-aged Bulgarian men. the Heath-Carter method was used to identify the anthropometric somatotypes of 860 adult men, aged 30-50 years old, from the city of Plovdiv, located in Central Bulgaria. The men were divided into 4 age groups, in five-year intervals. In each case body height, weight and a series of skinfolds, circumferences and diameters were measured to calculate the somatotype. The SPSS package was used for the statistical analysis. the results show a prominent endo-mesomorphic model in the study sample of male population. We found age-related increase of the values of the musclebone component, retention of the level of the fatty component and a decline in the ectomorphy. Regardless the quantitative changes of the three components, the correlation between them remains constant and the mean somatotype is preserved. A greater variety of morphotypes is found in the group of men aged 30-35. The most homogeneous group is that of the 45-50 year old men. This group is entirely dominated by the mesomorphic component (strength), and the endomorphic component (obesity) is greater than the ectomorphic one (linearity). the study finds that in the years between 30 and 50 the men tend to build muscle rather than fat. The 50 year-old men are more mesomorphic than the men at the age of 30, but they are shorter and with less elongated body segments. Copyright AULA MEDICA EDICIONES 2014. Published by AULA MEDICA.

  17. IN DEFENSE OF BULGARIAN CONSUMERS AND PRODUCERS – THE PROBLEM OF SURPLUS CHARGES AND DISCOUNTS

    Directory of Open Access Journals (Sweden)

    Krasimir Davchev

    2015-03-01

    Full Text Available In a market economy the term "market price" should reflect the market opportunities of users (amount of income and not to violate the economic interests of the producers. Structure of the economy is such that the predominant not only in Bulgaria but also in the other European countries is the sector of trade and services, where the main income for the traders are the margins or surplus charges. The article contains an analysis of the surplus charges of three main commodity groups - white flour, oil and sugar based on official data from the Ministry of Agriculture and Food. The analysis covers margins of the three major sales markets of food - commodity markets, large retail chains and other stores for retail sale. The results suggest that in addition to the normal surplus charges for wholesale and retail, there are the so called by the author "parasitic surplus charges" that are not controlled nor penalized in any way. In this respect, the author proposes the adoption by the Council of Ministers Regulation on the surplus charges with which to resolve this problem. Moreover, the author notes, and there are plenty of discounts that major retailers impose on Bulgarian producers and suppliers. Since these traders do not fall under the legal concept of "dominant market position", they are not sanctioned by the Commission for Protection of Competition. In this regard, the author suggests introducing in the Law on Protection of Competition concept of "economic dependence" or the preparation of sectoral trade law with which to regulate not only this issue but also trade margins.

    The main targets were: to investigate the parameters for optimizing the drying process as steam pressure, fluidization velocity and particle size; to identify the cost of drying and combustion processes considering the necessity of milling the coal (raw or dried). Test series with Bulgarian brown coal from Maritsa-East has been made. Two fractions with different particle size was got: A from 0 to 1.6 mm (0.5 mm average) and B, resp. 1.6 to 6.3 (1.7 mm). The particle size is depending on the coal moisture. The fluidized bed process with the both fractions was performed at variations of the following parameters: steam velocity (0.07 to 1.7 m/s); raw coal feed rate (4 to 16 kg/h); raw moisture (18 to 43 wt %) and pressure (1.3 and 5 bar). Also the shrinking behaviour of the coal in different pore sizes was tested. Comparing pore size of the oven dried coal to the fluidized bed dried coal, significantly higher inner surface for the oven dried coal was established. To indicate the pore size of raw coal samples were made by freeze drying. Ice expanding should cause higher inner surface compared to oven drying method but no significant difference was established. A significant increase of heat transfer of the particles from A fraction (300 to 350 W/m 2 K0 compared to B (200 to 230 W/m 2 K) was determined. The heat transfer coefficient increased at increasing of the raw coal feed rate, mostly significant for A, due to higher particle contact. In conclusion: the particle convective mechanism is predominant for the heat transfer; development of pressurized fluidized bed drying is not of interest and the question about the total expenditure for crushing and milling remains open

    Full Text Available A contribution to the study of Serbo-Bulgarian relations in the 1230s The enquiry into the cult of relics and its manifestations such as miracle working, transfer of mortal remains and the act of translatio that involves the topos of furta sacra relies on two lives of St Sava of Serbia, one penned by Domentijan (Domentianus, the other by Teodosije (Theodosius. The hagiographic episodes most relevant to this enquiry are certainly those describing Sava's stay in Tirnovo, his death (1236 and the translation of his remains to his homeland (1237. The narrative about the future saint's stay and death in Tirnovo gives conscious hints of the hero's sanctity using various hagiographic devices. Especially interesting to us is the account of the miracle Sava worked in Tirnovo while officiating the Epiphany service at the church of the Forty Martyrs. According to our analysis, the reference to the Epiphany service and the association of the miracle with that particular feast are certainly not an accident. The ideology of the Second Bulgarian Empire attached great importance to the epic victory over the Romaioi at the Battle of Tryavna in 1190, which was commemorated annually on the Day of Epiphany. The Byzantine historians Niketas Choniates and George Akropolites report that the Bulgarians seized the imperial insignia during the battle. It is irrelevant whether Sava's two hagiographers were aware of the importance of the feast or simply reiterated the well-known information about the service celebrated on that day at the church of the Forty Martyrs; what is quite certain is that the great honour of officiating the service-a celebration pregnant with symbolism-was bestowed upon the most distinguished guest and that it was then that, we believe not at all by chance, his miracle-working power was manifested in public-in front of the Bulgarian tsar, all clergy and the notables. As a natural consequence of the power of working miracles manifested in one

    Full Text Available On the Dictionary of Semantic Equivalents in Polish, Bulgarian and Russian Leksykon odpowiedniości semantycznych w języku polskim, bułgarskim i rosyjskim [The Dictionary of Semantic Equivalents in Polish, Bulgarian and Russian] is the first Polish dictionary which compares semantic equivalents in the largest languages of each Slavic subgroup: The West Slavic group (Polish, the South Slavic group (Bulgarian and the East Slavic group (Russian. The content of the dictionary reflects the social processes, changes and trends which have taken place over recent years. The dictionary consists of 5 volumes, with approximately 5000 entries for each language. What sets it apart from other dictionaries is that it ventures beyond the standard vocabulary one might expect from a dictionary of this sort. Leksykon also contains neologisms as well as realogisms - words which do not often have perfect equivalents in other languages because they are so deeply embedded in a nation’s culture. Each entry in the dictionary offers state-of-the-art semantic and syntactic categorisers, developed by Polish experts in Slavic semantics and aspectology. We consider the dictionary to be an innovation in lexicography, because its open structure enables more languages to be added in the future, including non-Slavic languages. Developed with the use of the most recent methodologies available, the dictionary will constitute a sound basis for lexicographic research in the future, in particular for the development of multilingual electronic dictionaries. In the 21st century, we face two great challenges: to make academic research more interdisciplinary and to build an integrated multinational European community. We hope that our dictionary will help address these challenges by promoting multilingualism and facilitating intercultural communication.The primary language of the dictionary is Polish - the largest Slavic language in the European Union.

    Humans are exposed to ionizing radiation all the time, and it is known that it can induce a variety of harmful biological effects. Consequently, it is necessary to quantitatively assess the level of exposure to this radiation as the basis for estimating risks for their health. Spacecraft and aircraft crews are exposed to elevated levels of cosmic radiation of galactic and solar origin and to secondary radiation produced in the atmosphere, the vehicle structure and its contents. The aircraft crew monitoring is required by the following recommendations of the International Commission on Radiological Protection (ICRP) (ICRP 1990), the European Union (EU) introduced a revised Basic Safety Standards Directive (EC 1997) which, inter alia, included the exposure to cosmic radiation. This approach has been also adopted in other official documents (NCRP 2002). In this overview we present the results of ground based, mountain peaks, aircraft, balloon and rocket radiation environment monitoring by means of a Si-diode energy deposition spectrometer Liulin type developed first in Bulgarian Academy of Sciences (BAS) for the purposes of the space radiation monitoring at MIR and International Space Station (ISS). These spectrometers-dosemeters are further developed, calibrated and used by scientific groups in different countries. Calibration procedures of them are performed at different accelerators including runs in the CERN high-energy reference field, simulating the radiation field at 10 km altitude in the atmosphere and with heavy ions in Chiba, Japan HIMAC accelerator were performed also. The long term aircraft data base were accumulated using specially developed battery operated instrument in 2001-2009 years onboard of A310-300 aircrafts of Czech Air Lines, during 24 about 2 months runs with more than 2000 flights and 13500 flight hours on routes over the Atlantic Ocean mainly. The obtained experimental data are compared with computational models like CARI and EPCARD. The

    Each Member State of the European Union is currently committed to produce national legislation, demonstrating conformity with the European Directive on medical exposures. According to the Directive, each country shall estimate the medical exposure of its population. For this purpose it is necessary to calculate the individual effective dose from each type of diagnostic radiology examination and the frequency of the examinations. The collective effective dose (CED) is disputable indicator for the medical exposures but it is a criterion for the level of the country on the radiation protection of persons undergoing medical exposure. The individual effective doses from each type of diagnostic radiology examination will depend on the patient's age, sex, weight, the number and type of images, the screening time and also the equipment used. Some mean values can be obtained through surveys of patient dose and compared with the national or European reference doses for 'standard sized' patients. The aim of this investigation is to assess the exposure of Bulgarian population undergoing diagnostic radiology examinations. The diagnostic radiology procedures are in 30 positions, distributed in 3 age groups: 0 - 17 y., 17 - 45 y. and over 45 y. For the assessment of the CED the generally accepted formula has been applied. The individual effective doses have been established on the basis of standard tablegrams for the radiographic diagnostic examinations and the results from the national research project 'Phare' in 2002. Presented data are: average number of examinations 3848.92x10 3 , frequency in thousands 500, annual effective individual dose 0.89 mSv/y and average annual collective effective dose - 3314.59 man.Sv/y. The mean effective dose per caput of population for medical exposures can then be compared with that of other countries having similar levels of health care. Comparisons can also be made with exposure of the population from other sources of radiation. The dynamics

    Full Text Available The article covers the last period of church-administrative activity of the Sofia’s metropolitan Stephаn (Shokov. The author describes the testimonies of contemporaries about the character and personal qualities of this ambiguous hierarch. In 1945–1948 metropolitan Stephan was the exarch of the Bulgarian Orthodox Church and participated in the Meeting of heads and representatives of Autocephalous Orthodox Churches in 1948. The author considers the circumstances of the dismissal of metropolitan Stephаn and his exile as especially important and interesting ones. The meeting of 1948 became the critical event in the exarch’s destiny. Being the supporter of ecumenism, metropolitan Stephen tried unsuccessfully to convince Patriarch Alexis of his rightness in order not to allow the condemnation of ecumenical contacts by the Moscow meeting. However Moscow looked on ecumenism differently in those days. In Moscow the Soviet management aspired to establishment of the centre of World Orthodoxy and tried to cite the Moscow Patriarchy against Constantinople that was under the influence of the USA and the Great Britain. As the Constantinople Patriarchy approved the ecumenical movement, the Moscow Patriarchy has been forced to take of an opposite position. Therefore, the participation of the Russian Church and Churches of the socialist countries in the ecumenical movement was impossible. Metropolitan Stephan, supporting the superiority of the Moscow Patriarchy in the World Orthodoxy, supported the active participation of all Local Churches in the ecumenical movement. The communistic management applied the maximum force to the exarch in order he has not made undesirable statements at the meeting. The fate of metropolitan Stephan has been decided after this meeting. In 1948 he was fired and exiled. The Moscow Patriarchy did not exclude the possibility of moving of metropolitan Stephаn to Russia and his location in any monastery. However metropolitan

    Full Text Available Information about the genetic variation among cultivars of vegetable crops is of vital importance for improvement of plant breeding programmes worldwide. The objectives of this study were to group 19 pepper (Capsicum annuum L. cultivars from the collection of Maritsa Vegetable Crops Research Institute, Plovdiv, Bulgariainto clusters according to their distances as estimated by agronomic traits and 9 di-and tri -nucleotide inter simple sequence repeat polymorphism (ISSR markers and to assess the relationships between them. The phenotypic characterization during 3 consecutive years revealed significant differences among Bulgarian cultivars for the studied 13 phenotypic traits. The biplot analysis of quantitative traits showed that the most strongly correlating traits with the first axis (55.6% of variance were fruit width, fruit weight and pericarp thickness (in the negative direction of the axis, and plant height (PH (in the positive direction. The most discriminative traits, considering the second axis (22.6% of variance were fruit length (FL and to a lesser extent the stem height (StH. The correspondence analysis of the qualitative traits showed that the intensity of the colour of the fruit (before and at maturity, fruit colourbefore maturity and fruit shape in longitudinal section were the most discriminative characteristics for the first two dimensions. The agronomic traits data and 7 dinucleotide ISSR primers were used to estimate the pairwise genetic distances. Higher mean phenotypic distance (0.414 in comparison to the genotypic ones (0.214 among the cultivars was observed, indicating higher phenotypic diversity among them. A highly significant, positive correlation between the agronomic data and ISSR marker-based matrices (r=0.41, p=0.001was detected. This indicates that ISSR distance tended to reflect that of the agronomics ones. However, additional molecular studies and large collection of highly diverse genotypes are needed to reveal

    At present there is not enough data about different types of radiation on Bulgarian essential oils isolated from medicinal plants. Here we report for the first time our studies on the effects of UV-radiation (290 nm to 320 nm) and γ-radiation (doses of 5 Gy, 10 Gy, 20 Gy and 30 Gy) on Bulgarian lavender essential oil isolated from Lavandulla angustifolia Mill. A spectrophotometry method was used for evaluation of the changes in the reducing power of the Bulgarian lavender oil before and after radiation. The electron donation potential of non-irradiated oil was found to be lower (0.268 ± 0.0244) than those of both, UV-irradiated (0.336 ± 0.0121) and γ-irradiated, oil samples (0.427 ± 0.0251 at 5 Gy radiation, 0.341 ± 0.0371 at 10 Gy; 0.328± 0.0173 at 20 Gy). By direct electron paramagnetic resonance (EPR) spectroscopy, single almost symmetrical EPR signals with different values of the g-factor were registered in non-irradiated (g = 2.0047 ± 0.0002), UV-irradiated (g = 2.01050 ± 0.00005) and γ-irradiated oil samples (g = 2.0017 ± 0.0002), respectively. EPR spectroscopy was used for assessment of the radical scavenging capacity of the non-irradiated and UV- and γ-irradiated samples of the Bulgarian lavender oil towards the stable free radical 1,1-diphenyl- 2-picrylhydrazyl (DPPH). Excellent DPPH radical scavenging capacities were found for UV- and 30 Gy-irradiated lavender oil samples. Based on these preliminary results, we consider that, after proper UV- or γ-radiation treatment, Bulgarian lavender oil might find application as a good radioprotector and antioxidant in cosmetics and medicine

    Earthquakes The area is famous with its seismic regime. The region usually shows non regular behavior of the strong events occurrence. There are episodes of activation and between them long periods of seismic quiescence. The most important one is at the I-st century BC when according to the chronicler Strabo, the ancient Greek colony "Bisone sank in the waters of the sea". The seismic source is known as Shabla-Kaliakra zone with the best documented seismic event of 31st March 1901. This event had a magnitude of 7.2 (estimated by the macroseismic transformation formula) with a source depth of about 10-20 km. The epicenter was located in the aquatory of the sea. The observed macroseismic intensity on the land reached the maximum value of X degree MSK. This event produced a number of secondary effects - landslides, rockfalls, subsidence, extensive destruction of the houses located around and tsunami (up to 3 meters height observed at Balchik port. This event is selected as referent one. Tsunamis Such earthquakes (magnitude greater then 7.0) almost always trigger tsunamis. They could be generated by the earthquake rupture process, or more frequently by the secondary triggered phenomena - landslides (submarine or surface) and/or other geodynamic phenomena - rock falls, degradation of gas hydrates, etc. the most famous water level change is described by Strabo - related to the great catastrophe. The area shows also some other expressions about tsunamis - the last one - a non seismic tsunami at 7th May, 2007 with maximum observed amplitudes of about 3 meters water level changes. Landslides The area on the north Bulgarian Black Sea coast is covered by many active landslides. They have different size, depth and activation time. Most of them are located near the coast line thus presenting huge danger about the beaches, tourist infrastructure, population and historical heritage. The most famous landslide (subsidence) is related with the I-st century BC seismic event, when a

    The development of the Bulgarian Emergency Response System (BERS) for short term forecast in case of accidental radioactive releases to the atmosphere has been started in the mid 1990's [1]. BERS comprises of two main parts - operational and accidental, for two regions 'Europe' and 'Northern Hemisphere'. The operational part runs automatically since 2001 using the 72 hours meteorological forecast from DWD Global model, resolution in space of 1.5o and in time - 12 hours. For specified Nuclear power plants (NPPs), 3 days trajectories are calculated and presented on NIMH's specialized Web-site (http://info.meteo.bg/ews/). The accidental part is applied when radioactive releases are reported or in case of emergency exercises. BERS is based on numerical weather forecast information and long-range dispersion model accounting for the transport, dispersion, and radioactive transformations of pollutants. The core of the accidental part of the system is the Eulerian 3D dispersion model EMAP calculating concentration and deposition fields [2]. The system is upgraded with a 'dose calculation module' for estimation of the prognostic dose fields of 31 important radioactive gaseous and aerosol pollutants. The prognostic doses significant for the early stage of a nuclear accident are calculated as follows: the effective doses from external irradiation (air submersion + ground shinning); effective dose from inhalation; summarized effective dose and absorbed thyroid dose [3]. The output is given as 12, 24, 36, 48, 60 and 72 hours prognostic dose fields according the updated meteorology. The BERS was upgraded to simulate the dispersion of nuclear materials from Fukushima NPP [4], and results were presented in NIMH web-site. In addition BERS took part in the respective ENSEMBLE exercises to model 131I and 137Cs in Fukushima source term. In case of governmental request for expertise BERS was applied for environmental impact assessment of hypothetical accidental transboundary

    Full Text Available The aim of the present study was to measure and evaluate the total lipids, fatty acid profile, retinol content and alpha-tocopherol content in the edible tissue of four commercially important fish species from the Bulgarian Black sea: Sprat (Sprattus sprattus, Round Goby (Neogobius rattan, Black Sea Horse Mackerel (Trahurus medditeraneus ponticus and Shad (Alosa pontica. Fat soluble vitamins were analyzed simultaneously using an HPLC system. The highest content of retinol was established in the Sprat (142.3 ± 4.4 μg/100g and the highest content of alphatocopherol was found in the Black Sea Horse Mackerel (1112.7 ± 39.2 μg/100g. The fatty acid (FA composition was analyzed by GC/MS. The content of omega 3 (n3 FAs was significantly higher (p , 0.001 than the content of omega 6 (n6 FAs in each of the analyzed fish samples. The n6/n3 FA ratio was within the recommended range (0.20–1.50 for Sprat, Round Goby and Shad. Relatively high levels of retinol and alpha-tocopherol, FA composition, n3/n6 FA and PUFA/SFA ratios indicate that these fish species have good nutritional quality.

    Development of the appropriate methods and techniques for marine and atmospheric radioactivity measurements in the NIMH-BAS during the last 5 years is presented. Approaches for pre-concentration of the radionuclides from the atmosphere and sea water samples followed with reliable radiochemical methods for radionuclides separation and low level counting are discussed. Dissolved radiocesium concentrations measured in a period of time starting in 1993 show some decrease with years and spatial variations probably due to the hydrophysical features of the sampling sides - the lower measured concentrations during 1995 and 1998 correspond to the lower salinity. Application of the radiochemical separation of Plutonium, Thorium, 90 Sr and Americium on the samples from the Bulgarian Black Sea coastal region is reported. (author)

    1995-01-01

    Quantitative CT assessment of bone mineral content (BMC) is widely used in clinical practice. The results obtained from the examination of every single patient are compared with the reference values for the corresponding age and sex. It is known that BMC shows well recognized genetic, racial, ethnic and other differences. On the other hand, the introduction of different techniques, calibration phantoms, algorithms for choosing the region of interest, statistical models etc. leads to some differences in reference values. The authors present their own studies on the reference values of BMC in Bulgarian women using single energy quantitative computed tomography and a liquid K 2 HPO 4 calibration phantom. Different statistical models for data processing are proposed. The results are compared to the studies of recognized foreign authors. 17 refs., 3 tabs., 5 figs. (author)

    Mercury capture by fly ash C was investigated at five lignite- and subbituminous-coal-burning Bulgarian power plants (Republika, Bobov Dol, Maritza East 2, Maritza East 3, and Sliven). Although the C content of the ashes is low, never exceeding 1.6%, the Hg capture on a unit C basis demonstrates that the low-rank-coal-derived fly ash carbons are more efficient in capturing Hg than fly ash carbons from bituminous-fired power plants. While some low-C and low-Hg fly ashes do not reveal any trends of Hg versus C, the 2nd and, in particular, the 3rd electrostatic precipitator (ESP) rows at the Republika power plant do have sufficient fly ash C range and experience flue gas sufficiently cool to capture measurable amounts of Hg. The Republika 3rd ESP row exhibits an increase in Hg with increasing C, as observed in other power plants, for example, in Kentucky power plants burning Appalachian-sourced bituminous coals. Mercury/C decreases with an increase in fly ash C, suggesting that some of the C is isolated from the flue gas stream and does not contribute to Hg capture. Mercury capture increases with an increase in Brunauer-Emmett-Teller (BET) surface area and micropore surface area. The differences in Hg capture between the Bulgarian plants burning low-rank coal and high volatile bituminous-fed Kentucky power plants suggests that the variations in C forms resulting from the combustion of the different ranks also influence the efficiency of Hg capture. ?? 2010 Elsevier Ltd.

    The new Bulgarian Act on the Safe Use of Nuclear Energy (ASUNE) was adopted in the year 2002. It replaced the former Act on the Use of Nuclear Energy for Peaceful Purposes, which was in force for about 17 years. The ASUNE covers the activities involving nuclear energy and sources of ionizing radiation mainly by establishing a consistent authorization regime. It is an up-to-date act, based on the IAEA requirements and standards, and yet fully in compliance with the Bulgarian legislative system. The newly adopted Act is based on the following main principles: Priority of safety over economic and other social needs; Occupational and public exposure to ionizing radiation to be kept as low as reasonably achievable (ALARA); Direct and personal liability of the licensee/permit holder; Independence of the regulatory body; Application of a less prescriptive approach; Issuing of authorizations under conditions of legal equality and transparency

    The Program on Energy Efficiency in the Industry was initiated in 1991 by the US Agency for International Development in cooperation with the Bulgarian Ministry of the Industry and Commerce and the Committee for Energy (CE). Within this program a series of energy audits in 8 firms, representative for different sectors of the industry, was carried out. In 1992 the joint teams of CE, the firm Ekotekhproduct, Intern Resources Group (USA) and employees of the chosen firms completed an audit programme, aiming at facilitating the development of an energy conservation policy by providing data for establishing the measures and investment priorities for energy efficiency improvement. The measurements and the results of the carried out equipment set-ups undoubtedly proved the presence of vast recourses for energy conservation in low or zero investment procedures including measures in the following fields: setting of the combustion processes of the steam generators and water heating boilers; insulation repairs; elimination of leakages; condenser chambers repairs. The estimated gains in efficiency, the recourse conservation and the expected requites are presented for each case and for each site under study. 17 general causes for inefficient energy consumption in the industry are enumerated, among which: equipment run-down, careless operation and maintenance practice, lack of advanced control devices, lack of consistent concept for information flows, lack of control and maintenance and lack of incentives for actuation of energy conservation measures. 1 tab.

    2014-11-15

    Underground coal gasification (UCG) allows for exploitation of deep-seated coal seams not economically exploitable by conventional coal mining. Aim of the present study is to examine UCG economics based on coal conversion into a synthesis gas to fuel a combined cycle gas turbine power plant (CCGT) with CO2 capture and storage (CCS). Thereto, a techno-economic model is developed for UCG-CCGT-CCS costs of electricity (COE) determination which, considering sitespecific data of a selected target area in Bulgaria, sum up to 72 Euro/MWh in total. To quantify the impact of model constraints on COE, sensitivity analyses are undertaken revealing that varying geological model constraints impact COE with 0.4% to 4%, chemical with 13%, technical with 8% to 17% and market-dependent with 2% to 25%. Besides site-specific boundary conditions, UCG-CCGT-CCS economics depend on resources availability and infrastructural characteristics of the overall energy system. Assessing a model based implementation of UCG-CCGT-CCS and CCS power plants into the Bulgarian energy network revealed that both technologies provide essential and economically competitive options to achieve the EU environmental targets and a complete substitution of gas imports by UCG synthesis gas production.

    Full Text Available Throughout the world today there are about 80 countries which practice various winter sports. Regardless of the wide geographical range demand in terms of existing infrastructure is highly concentrated in a few regions of the world. To be competitive ski resorts have to deliver good experiences and excellent value to tourists. Current community officials and destination managers of the Bulgarian ski resort of Bansko believe that the main weakness of this ski centre is the extensive waiting at the bottom gondola station and advocates expansion of the ski runs and lift capacity. The aim of the article is to research the strengths and weaknesses of the resort in regional and world context and to prove that further expansion will not forge a strong emotional connection with visitors and thus will not bring success in destination markets. The methodology used in this article follows three steps: 1 Literature review on the nature of the ski market in the world, as well as factors contributing to effective destination management; 2 International, national and regional data analysis of existing secondary data on winter sports market and 3 Qualitative study carried out with a purposive sample of key informants. The SWOT analysis based on the results of the qualitative study show that touristic shareholders in Bansko should apply an appropriate strategy for small winter resorts by offering a unique product that speaks to the world instead of trying to promote universal broad product for the mass market.

    The energy demand during the next century due first of all to the expected growth of population necessitates more efficient technologies and huge investments. The production of nuclear energy requires higher safety as well as reduction of costs. A new form of partnership between the developed and developing countries is needed for transferring capital and technologies at special framework terms in order to avoid errors in the process of transition. The Energy Forum'99 highlights the current problems of Bulgarian energy branch and the projects for its future including better utilization of the existing energy resources, for development of new or renewable energy sources, not well utilized at present, and to harmonize the sector with better environmental protection. The most important problems discussed are: 1. Structure and restructuring strategy of the energy sector. Prices and tariffs. Privatization aspects. Construction of new replacement generating capacities; 2. Thermal power plants; 3. Nuclear power plants; 4. District heating and natural gas supply; 5. Efficient energy utilization; 6.

    Full Text Available As a field of culture, the family enterprise shows that in the current European societies the economic operation does not proceed only from a purely rational point of view and that notwithstanding the common speaking of globalization, the local may be a prerequisite for successful economic development. My objective has been to show, proceeding from an example from a small Bulgarian town, that the family enterprise is a field of culture in which the observed phenomena are strongly influenced by the social inclusion of the enterprise and by its tie-up with the context of the urban environment. I shall investigate in what way local social and cultural resources are intensively used in the process of setting up and functioning of a family enterprise from the sphere of hoteldom and tourism in the town of Belogradchik. I intend to study whether these resources are conducive to the economic prosperity of the firm. Another research objective is to establish the manner of identification of the enterprise with the town, with the region and the local culture by way of the services provided (tourist and restaurant. I shall look for an answer to the question of how the enterprise’ working realm fits in the concrete cultural, historical and social context of the town.

I 37 preserved in Russian National Library (S.-Petersburg and dated to the beginning of the 13th c. Numerous linguistic features of the manuscript testify to Old West Bulgarian (Old Macedonian literary usage of the end of the 9th — beginning of the 10th c., on the basis of which the earliest Slavonic hymnographical translations were performed. Despite of such an archaic linguistic and textual layers observed in the manuscript, its calendar, structure and content were influenced by the monastic rite based on the Typicon of Patriarch Alexius the Studite which had been translated and introduced in Kievan Rus' at the second half of the 11th c. The linguistic features of the text version as attested by F. p. I 37 have been compared to the manuscripts testifying to the Alexius the Studite text version. It has been affirmed that adaptation of the Old Bulgarian hymnographic heritage in Kievan Rus' followed the unstable trend to neglect the most remarkable South (and South West Slavonic lingustic features and aimed at establishing “neutral” over dialectal Church Slavonic literary usage. The significant part of the article contains the edition of the earliest Slavonic, i.e., Old Bulgarian, translation of the Greek kanon Τάφῳ παρθενοδόχῳ dedicated to the Dormition of the Theotokos. The earliest Slavonic translation of this kanon has been preserved in the unique available manuscript, that is F. p. I 37. The publication of the Slavonic translation is supplied with the first critical edition of the Greek source performed on the basis of twelve manuscripts, the linguistic commentary of the Slavonic text, and remarks concerning some metric peculiarities of the original Greek version.

  7. Co-engineering Participatory Water Management Processes: Theory and Insights from Australian and Bulgarian Interventions

    Directory of Open Access Journals (Sweden)

    Katherine A. Daniell

    2010-12-01

    Full Text Available Broad-scale, multi-governance level, participatory water management processes intended to aid collective decision making and learning are rarely initiated, designed, implemented, and managed by one person. These processes mostly emerge from some form of collective planning and organization activities because of the stakes, time, and budgets involved in their implementation. Despite the potential importance of these collective processes for managing complex water-related social-ecological systems, little research focusing on the project teams that design and organize participatory water management processes has ever been undertaken. We have begun to fill this gap by introducing and outlining the concept of a co-engineering process and examining how it impacts the processes and outcomes of participatory water management. We used a hybrid form of intervention research in two broad-scale, multi-governance level, participatory water management processes in Australia and Bulgaria to build insights into these co-engineering processes. We examined how divergent objectives and conflict in the project teams were negotiated, and the impacts of this co-engineering on the participatory water management processes. These investigations showed: (1 that language barriers may aid, rather than hinder, the process of stakeholder appropriation, collective learning and skills transferal related to the design and implementation of participatory water management processes; and (2 that diversity in co-engineering groups, if managed positively through collaborative work and integrative negotiations, can present opportunities and not just challenges for achieving a range of desired outcomes for participatory water management processes. A number of areas for future research on co-engineering participatory water management processes are also highlighted.

    The purpose of this study was to examine the influence of local culture on body image and eating distress in a sample of urban Bulgarian women. Specifically, we focused on two affiliated factors unique to the Bulgarian context: faith and traditional fasting. Findings revealed that women could be divided into two groups who behaved differently based on the severity of their eating disorder symptomatology. For women with higher EAT-40 scores (i.e., vulnerable women), faith seemed to have harmful effects, perhaps by virtue of motivating or reinforcing asceticism and dietary restraint. For these women fasting was likely but one strategy for weight management and the achievement of a desired thin figure consistent with the socio-cultural models. In contrast, among women with lower EAT-40 scores, faith seemed to have a protective effect against excessive dieting. These women were more likely to use fasting in the way intended by religious scripture, for faith-related reasons that have nothing to do with body image. This study contributes to the literature by emphasizing the importance of culturally unique factors that may be implicated in the relationship between body dissatisfaction and overt eating distress in the trans-cultural context. When expanded, this research can be of use in helping formulate custom interventions and public health policies aimed at preventing such conditions in Bulgaria and possibly in similar post-communist cultures.

    Full Text Available Objectives: On the basis of the results from an empirical study this research aims at exploration of the prerequisites for the establishment of an integrated cultural identity within Romanian-Bulgarian Cross-Border Region along the Danube River (RBCBR. Prior Work: The paper is trying to prove the necessity of identity re-negotiation process within RBCBR. The theoretical background of the research is related to some of the most topical considerations in this scientific field. Approach: The research uses an interdisciplinary approach and combines the perspectives of regional studies, cross-cultural psychology and intercultural communication. A representative survey is the main instrument of the research. Results: Among the citizens of the RBCBR there exist favourable attitudes towards closer relations with their neighbours which can serve as a key element of the identity re-negotiation process within the region. Implications: The research results can be used by policy makers and regional authorities in the process of establishment of a new policy for territorial cooperation as well as by researchers in further development of this topic area. Value: the importance of the research is in its new approach towards the establishment of integrated regional identity as well as in the comparison of the Romanian and Bulgarian attitudes towards cooperation in the neighbourhood area.

    Developmental testing is essential for early recognition of the various developmental impairments. The tools used should be composed of items that are age specific, adapted, and standardized for the population they are applied to. The achievements of neurosciences, medicine, psychology, pedagogy, etc. are applied in the elaboration of a comprehensive examination tool that should screen all major areas of development. The key age of 5 years permits identification of almost all major developmental disabilities leaving time for therapeutic intervention before school entrance. The aim of the research is to evaluate the developmental performance of 5-year-old Bulgarian children using the approach of translation neuroscience. A comprehensive test program was developed composed of 89 items grouped in the following domains: fine and gross motor development, coordination and balance, central motor neuron disturbances, language development and articulation, perception, attention and behavior, visual acuity, and strabismus. The overall sample comprises 434 children of mean age 63.5 months (SD-3.7). Male to female ratio is 1:1.02. From this group, 390 children are between 60 and 71 months of age. The children are examined in 51 kindergartens in 21 villages and 18 cities randomly chosen in southern Bulgaria. Eight children were excluded from the final analysis because they fulfilled less than 50% of the test items (7 children did not cooperate and 1 child was with autistic spectrum disorder). The items with abnormal response in less than 5% of the children are 43. The items with abnormal response in 6% to 35% of the children are 37. The items with high abnormal response (more than 35%) rate are only 9. The test is an example of a translational approach in neuroscience. On one hand, it is based on the results of several sciences studying growth and development from different perspective. On the other hand, the results from the present research may be implemented in other

    2009-01-01

    The energy sector in Bulgaria has undergone major restructuring in recent years. It faces the dual challenges of achieving regulatory stability to attract private investors, and creating a functioning competition energy market. As of the EU Accession in 2007, Bulgaria has fully liberalized power and gas markets. The 2003 Energy Law establishes the energy sector legal framework and sets the basis for creation of a transparent and predictable regulatory environment where the key regulatory responsibilities are vested with the State Energy and Water Regulatory Commission (SEWRC). The energy sector experienced significant problems in the first half of 2007 due to lost production capacities and regulatory failures on the electricity market. Excess price regulations on the market of electricity supplies to household, coupled with insufficient liberalization of imports and exports, create unfavorable conditions for power producers and large electricity users. The energy regulator has tried to achieve several incompatible targets as of July 1, 2007 for maintaining low electricity prices for households in response to political pressure, low power generation prices amid rising input costs, and market opening in compliance with EU regulations.

  17. THE PHRASEOLOGY OF “HEAD” IN RELATION WITH BALKAN MENTALITY (CONTRASTIVE ANALYSIS OF THE PHRASEOLOGY OF ALBANIAN, BULGARIAN AND GREEK LANGUAGES

    Directory of Open Access Journals (Sweden)

    Eva ÇËRAVA (KANE

    2014-05-01

    Full Text Available The common points in the phraseology of Balkan languages are often attributed to some “Balkan cultural heritage”, a term which is usually not defined any further. So, this term can allow us to see how this her itage is represented in phraseology. First of all, the use of a systematic empirical research to describe these phraseological units serves to determine which idioms actually share a relatively identical lexical and semantic structure across the three lang uages and could therefore be called “widespread”. This article presents a contrastive study of the structures and semantics of phraseology units containing the word “head” in Albanian, Bulgarian and Greek languages. This approach can describe similarities and differences of mentality as reflected in phraseology.

    Full Text Available For the first time an ecological study of the carabid fauna of the area of Cape Emine (Bulgarian Black sea coast was conducted. Over the period 2010 – 2011 adult carabid beetles were collected. The investigation was carried out at 7 sampling sites and pitfall traps were used. During the study altogether 6245 specimens were captured. The greatest number of both species and specimens was found in the steppe-like habitat, least – in the pine (Pinus nigra J. F. Arnold plantation. Indices for α- and β-diversity were calculated. The dominant structure of the whole carabid complex showed the presence of two eudominant, three dominant, two subdominant, eleven recedent and 85 subrecedent species. The analysis of the sex structure showed the total prevalence of males over females. Cluster analysis indicated a low percentage of taxonomic similarity between the communities, which reflected the diversity of the landscape.

    Modern clinical, radioisotopic and radioimmune methods were used for diagnosis of iron deficiency in 22 patients with anemic syndrome. The terapeutic effect of the new Bulgarian microcapsular iron-containing preparations FUMAFER-1 and FUMAFER-2 (additionally containing vitamin C and folic acid) was evaluated. It was established that in the patients following treatment the hemoglobin increased with 25 and 16,2 g/l respectively, the blood serum iron - with 5,2 and 3,3 mcmol/l, the ferritin - with 13,6 and 3,3 mg/l. It was concluded that the tested preparations were well tolerated by the patients and could be successfully used in cases of mild iron deficiency, which is most often encountered among the growing up and workable population

    The objective of this work is to investigate the distribution of underweight, overweight, the general and central obesity in 8-15-year-old Bulgarian children and adolescents, through the use of the anthropometric indices BMI and WHtR. Subject of this study are 878 children and adolescents (437 boys and 441 girls) of Smolyan region, Bulgaria, at the age of 8 to 15 years. The study is cross-sectional and was conducted in the period 2012-2014. The body height, weight and waist circumference were measured. In addition, the body mass index (BMI) and waist to height ratio (WHtR) were calculated. Overweight and obesity were defined according to the cut-off points of BMI, recommended of IOTF and developed by Cole et al. (2000; 2007). The central obesity was defined according to the discriminatory values of 0.500 of WHtR. The collected data were analysed by statistical software packages STATISTICA 10.0 and SPSS 16. Overweight occurs among 18.8% of the boys and 17.0% of the girls, and obesity occurs among 7.6% of boys and 3.7% of the girls. The underweight are 8.0% of the boys and 10.4% of the girls. Central obesity (WHtR ≥ 0.500) occur among average 12.75% of all investigated children independently of their nutritional status (16.2% of boys and 9.3% of girls). With central obesity (WHtR ≥ 0.500) are on average 2.7% of all boys and girls with normal weight (n = 96) and an average 46.82% of all participants with overweight and with obesity (n = 205). With increased health risk (WHtR ≥ 0.500) are total of 2.01% (n=16) of all surveyed children (n = 793) from categories normal weight. There has been an increase in prevalence of overweight and obesity among Bulgarian children and adolescents from Smolyan region during the over one last decade. The relatively high percentage of underweight children, especially among in group of the girls alter puberty. The central obesity, as well as its combination with overweight or general obesity is more frequent in boys than in girls

    The Noise Sensitivity Scale Short Form (NSS-SF), developed in English as a more practical form of the classical Weinstein NSS, has not to date been validated in other cultures, and its validity and reliability have not yet been confirmed. This study aimed to validate NSS-SF in Bulgarian and to demonstrate its applicability. The study comprised test-retest (n = 115) and a field-testing (n = 71) of the newly validated scale. Its construct validity was examined with confirmatory factor analysis, and very good model-fit was observed. Temporal stability was assessed in a test-retest (r = 0.990), convergent validity was examined with single-item susceptibility to the noise scale (r = 0.906) and discriminant validity was confirmed with single-item noise annoyance scale (r = 0.718). The lowest observed McDonald's omega across the studies was 0.923. The cross-cultural validation of NSS-SF was successful but it proved to be somewhat problematic with respect to its annoyance-based items.

    Full Text Available Ground spices are a source of hazards for dry-fermented meat products. Since dry-cured sausages are not subjected to heat treatment, there is a high risk of microbial cross-contamination and physical impurities. The aim of this study was to determine effects of the replacement of 3 g/kg of ground black pepper (Piper nigrum L., and cumin (Cuminum cyminum with their aliquots of new freon extracts, and compare them with the effect of 0.2 g/kg antioxidant addition (taxifolin extract from Siberian larch (Larix sibirica Ledeb, rosemary (Rosmarinus officinalis L. extract, and butylated hydroxytoluene on sensory properties, color stability, proximate composition, free amino nitrogen and pH of Bulgarian-type dry-cured „Sudjuk“ sausages. The replacement of natural ground spices with aliquots of their extracts improved sensory properties and stabilized the color characteristics of the final product during 30 days of storage at 0–4°C. The addition of 0.2 g/kg rosemary extract was as effective as the addition of freon extracts on the overall assessment to the 14th day of the experiment. It was determined that the addition of antioxidants or spice extracts had no significant effect on proximate composition, pH, and free amino nitrogen accumulation of the “Sudjuk”. The addition of 0.2 g/kg, taxifolin or rosemary extracts and butylated hydroxytoluene was not so efficient in improving the sensory properties and color stabilization in comparison to the new freon spice extracts. The examined spice extracts can be successfully used to improve the quality of “Sudjuk” sausages.

    Full Text Available Phthalates are a large group of compounds with similar chemical structure widely used as plasticizers for plastics. They can easily be released from the polymer during usage and in this way enter the human body. Their adverse effect on health is known as "phthalate syndrome" and can impact children and adults alike. For children in particular, there is an additional potential risk of exposure to phthalates via toys intended for oral use. The Regulation (EC No 1907/2006 (REACH prohibits the use of bis (2-ethylhexyl phthalate (DEHP, di butyl phthalate (DBP and benzyl butyl phthalate (BBP as a substance or constituent of preparations at concentrations higher than 0.1 % in the plasticized material meant to toys and childcare items. The aim of this article is to quantify the content of DEHP, DBP and BBP in soft toys intended for children up to 3 years of age, including toys designed to be placed in the mouth. A method consisting of an extraction procedure of phthalates from polymers, purification of the extract, followed by GC/MS identification and quantification was validated. Three different techniques for phthalates’ extraction (Soxhlet, ultrasonic and vibrator were compared and the most effective one was chosen.This method was applied to the analysis of DEHP, DBP and BBP in soft toys from the Bulgarian market to establish their compliance with REACH requirements. All the tested toys contained at least one phthalate. Exceedence of the permitted content for DEHP, DBP and BBP (as sume, mainly due to the high levels of DEHP, was observed in several toys from retail.

    Full Text Available Rising interactions of asymmetrical exchange as a consequence of unequal access to economic resources create status differences between people. In that way some people are provided with authority benefits while the others are in dependent position. The situation of economic dependence arises when the object is seen by the subject like a unique source for personal needs gratification. The degree of dependence is right proportional to the object’s subjective significance for a particular person, group, organization, etc. This statement provokes the problem of dependence as a psychological phenomenon that defines personal behavior and the character of interactions in respect of actual needs gratification. Contrary, economic independence is associated with these resources that are the result of personal incomes, property, and capital dividends.

    2014-02-01

    Full Text Available A brief overview of the objective criteria and unified standards in tertiary technical education, developed and controlled by European professional associations is done. The reasons are given for which engineering mathematics is a serious barrier for the students in technical universities - lack of the constructive relationships between: universities and secondary schools; teachers and students in the learning process; discrepancies in the curricula of different university departments. The interdisciplinary approach is not used as a factor of motivation at different levels, and the contemporary teaching tools and methods are missing as well. The knowledge and skills evaluation and assessment are not organized effectively. Short and long term measures to overcome the math learning problems of the prospective engineers are indicated in respect to the basic educational principles. Experience in this line is shared - computer-based training aids and tests, compulsory term papers and consultations for the students with lower scores, teamwork is recommended. The long-term measures involve introducing the laboratory exercises, teacher's teams from different departments and faculties for common training materials and classes, joint work with faculty and students; attracting and training of good teachers and continuous improvement of their qualification.

    The creation and implementation of an adequate legal framework is important for eastern European countries in the field of combating organized crime, especially the illicit trafficking of radioactive materials, in these countries' efforts towards joining the European Union by adopting many legislative, economic and political frameworks for the combating of terrorism. The Republic of Bulgaria, as a PECO country in the phase of pre-adhesion to the European Union, is preparing its legislation and law enforcement institutions to meet the new challenges and tasks of the process of joining the European Union. One of the best ways to combat illicit trafficking is collaboration between neighbouring countries through connections between similar law enforcement bodies. The Institute for Nuclear Research and Nuclear Energy in Bulgaria and the Cekmece Nuclear Research and Training Centre in Turkey participated in a joint border exercise at the Kapi Kule checkpoint which provided a unique opportunity for law enforcement institutions and scientific experts to respond jointly in a simulated border incident with real nuclear materials.

    Full Text Available Abstract. A comparative analysis of amino acid composition of lamb meat from the North East Bulgarian fine fleece breed (I gr. and its crossbreds from internal breeding with 25% heredity from the Australian merino (II gr. and Ile de France (III gr. breeds was conducted. Upon starting the experiment lambs were equal and during the experiment they were placed under similar conditions of feeding and rearing. To establish the amino acid composition of meat slaughter analyses were performed at 100 and 130 days of age. From the carcass of each slaughtered animal individual mean samples were taken. Studies were carried out in the Research Laboratory of the Faculty of Agriculture at Trakia University. As a result of the studies the following conclusions were made: ¼ Ile de France crossbreds in a sophisticated crossing have the highest total amino acid content, including essential amino acids in the meat of 100- and 130-day-old lambs, 6.87% and 7.36%, respectively. The lysine/arginine ratio, relating to protein atherogenicity, varies within narrow ranges among groups and marks slight increase with age – from 1.31-1.37 at 100 days to 1.41-1.46 at 130 days. With the increase of age in crossbreds from internal breeding total protein amino acid content grows, that being most prominent in lambs from the III group – from 41.92 to 43.49%. The values of total protein indices increase compared to the reference protein (from 117.97% to 118.22% for II group and from 116.44% to 120.80% for III group and the whole egg protein (from 89.39% to 91.92% for II group and from 90.53% to 93.93 for III group. It has been found that internal breeding of crossbreds with 25% heredity from the Ile de France breed has positive effect concerning the total amino acid content of lamb meat at 100 and 130 days of age, essential amino acid content in it and the levels of total amino acid indices. Internal breeding of crossbreds with 25% heredity from the Australian merino breed

    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.

    CONCLUSION: Thanks to this new approach, some patients could avoid one surgical intervention, which could be interpreted as a significant advantage or probably also survival benefit. This methodology and its successful application were first officialised by the representatives of the Bulgarian Society for Dermatologic Surgery- (BULSDS, and the purpose of this action, in general, is to fully improve clinical management of patients suffering from cutaneous melanoma in terms of compactness by 1 reducing the number of unnecessary surgeries or the number of surgical interventions in general; 2 reducing side effects occurring in surgeries and 3 introducing a serious optimization in terms of financial resources needed or used in the second hospitalization of patients. The question remains open whether the accepted or the current recommendations for surgical treatment of melanoma will be transformed or adapted for the matching patient groups.

    Full Text Available “Playing catch up”. The notion of needing to accelerate a country’s progress towards a civilised paradise – the Bulgarian version (a proposed entry for a dictionary of peregrinating ideas This paper outlines the main stages in the process through which the notion of “needing to catch up” (a belief that the country was in need of accelerated development became incorporated into the idea of Bulgarian national identity. Since the mid-19th century, Bulgarians have tended to rely on the notion of “needing to catch up” as a way of conceptualising their place among “the civilised nations,” a concept they regard with varying degrees of desirability. I use the concept of “needing to catch up” in the sense of a culturally and politically functional standard or template, which nonetheless cannot function as an independent concept since it belongs to different systems of ideas with their various economic, geopolitical, religious, psychological and cultural aspects. Inseparably wedded to the idea of “needing to catch up” is the idea of “retardation”, which was floated in discussions on the Bulgarian condition even before the Bulgarian state emerged as a political reality. As the national movement grew in strength, these inferiority complexes morphed into their mirror image: a belief that Bulgarians were capable of catching up with Europe in terms of cultural advancement. From the early fascination with the cultural achievements of the “enlightened nation” felt by the so-called “Orthodox Enlightenment” thinkers, through a replication of the Russian discourse, this line of reasoning culminated in Marxist ideology (including propaganda between 1945 and 1989 and the post-1989 politics of persuasion. The bell may be tolling for the time-bound idea of “needing to catch up”, a notion which has exhausted its potential to excite intellectual conflict or struggle, and has very possibly resulted is a self-poisoning of the

This impasse, the paper argues, is largely due to the emergence of an organization-phobia that has come to seize several...... strands of theorizing. By attending to the wide-ranging and far-reaching history of this organization-phobia, the paper argues that OS has become increasingly incapable of speaking about its core object.

The mother component is line 10517 which possesses cytoplasmic male sterility, and the father component is line 10595R, a fertility restorer of branched type. Both parental forms have very good general and specific combining ability. Hybrid Valin is medium early, with vegetation period of 110 – 115 days, plant height 165 – 175 cm and head diameter 17 – 18 cm. The percent of kernel in seed is within the range of 65 – 73%. Seeds have absolute weight 50 – 55 g, and oil content in seed is 46 – 50%. The hybrid is resistant to lodging and moderately resistant to phoma and phomopsis. The resistance to downy mildew is as high as 95 % up to race 700, and the resistance to the parasite Orobanche is 100% (races A-F. In the breeding fields of DAI the hybrid went through threeyear testing according to a scheme and growing technology approved for this crop. During the first two years of the control testing it exceeded the mean standard by seed yield with 11.0% and 14.4%, respectively. During the third year, hybrid Valin was above the mean standard with 10.9% by seed yield and with 6.6% by oil yield in a unified competitive varietal testing. The maximum yield obtained at DAI was 4483 kg/ha, and the maximum oil content was 50.1%. In 2007 and 2008 hybrid Valin went through official testing within the structure of the Executive Agency of Variety Testing, Field Inspection and Seed Control of Bulgaria. By the index seed yield, the exceeding of the mean standard was 23.6 % in the first year, and in the second the yield was with 1.4 % below the standard. Oil content was a little below the standard in both years. The aim of this investigation was to make as full as possible a characterization of the new registered sunflower hybrid Valin on the base of biological, phytopatological and economical indices.

    As special attention is paid to geothermal energy because the geothermal sources are distributed all over the territory of Bulgaria. Governmental incentives for initiating national action programs for energy efficiency, new renewable sources and the environment as well as educational activities are particularly important. The energy sector, as any other sector of the national economy, is currently undergoing considerable changes on its way to market relations, primarily connected to determining the role of the state as well as the form of ownership. The state energy policy is based on a long - term energy strategy complying with the natural conditions of the country, the expected macro - economic development, the geopolitical situation and regional development of energy cooperation with neighboring and closely situated countries. Limited reserves of fossil fuels, increased local and global environmental risks and recent technological achievements have straightened the global importance of renewable sources of thermal and electric energy. This is even more relevant for Bulgaria with small fossil fuel reserves (lignite) to be nearly exhausted and the environment notably polluted. Concerning local renewable sources of thermal energy and electricity, it is necessary to re-estimate their strategic role, to complete the input data for the resources, also to establish national programs supported by research and educational activities and international cooperation.

    Somatic mutations in JAK2, MPL and CALR are recurrently identified in most of the cases with Philadelphia chromosome negative myeloproliferative neoplasms (MPNs). We applied four molecular genetic methods for identification of CALR exon 9 mutations, including high resolution melt (HRM) analysis, Sanger sequencing, semiconductor target genes sequencing and whole exome sequencing. A total of 78 patients with myeloid malignancies were included in the study. We identified 14 CALR exon 9 mutated cases out of 78 studied patients with myeloid malignancies. All mutated patients were diagnosed with MPN being either PMF (n = 7) or ET (n = 7). Nine cases had type 1 mutations and 5 cases had type 2 mutations. CALR exon 9, MPL exon 10 and JAK2 p. V617F were mutually exclusive. There were no statistically significant differences in the hematological parameters between the cases with CALR and JAK2 or MPL mutations. Notably, all four techniques were fully concordant in the detection of CALR mutations. This is one of the few reports on the CALR mutations frequency in South-eastern populations. Our study shows that the frequency and patterns of these mutations is identical to those in the patients' cohorts from Western countries. Besides we demonstrated the utility of four different methods for their detection.

    Full Text Available This is a non-fiction story about a grandmother teaching her six-year-old granddaughter how to knit. The child helps to wind the yarn into a ball and then patiently follows her granny's instructions, making stitch after stitch. The little girl's work is often uneven and is gently corrected. However, the small piece the child had knitted is used to patch up a tear in her grandfather's woolen glove. The lesson in knitting is transformed into a lesson in appreciation of one's work, no matter how small and insignificant it may seem. The narrative is permeated with the love between the grandmother and the child, who is the writer of the story.

    Full Text Available Although tinea capitis is the most common fungal infection in children, significant changes have been reported in its epidemiology worldwide, as a result from certain geographic, climatic and cultural differences in one hand, as well as the changes in its etiologic pattern. The clinical manifestation of the infection and the stage of inflammation vary from mild desquamation to severe suppurative indurated plaques in kerion - like the pattern, depending on the nature of the etiologic agent and the host-immune response. We report a case of tinea capitis profunda, caused by Trichophyton verrucosum in a 5 – year - old male patient, presented as a severe scalp and cutaneous desquamation, resembling histopathologically psoriasis, associated with severely indurated ringworm plaque in the temporal area. The performed histological examination revealed a psoriasiform pattern, without the typical Munro abscesses or Kogoj pustules. With the presented case, we want to emphasize the importance of the host’s immune reaction to zoophilic dermatophytes, such as Trichophyton verrucosum, resulting in severe and often atypical clinical manifestation, as well as the possible “Id reaction”, to avoid or minimise misdiagnosis and delayed therapy. The presented patient was treated with topical oleum acidy salicylic 10% and Terbinafine 125 mg daily with significant resolution of the complaints within the following two months.

    2007-01-01

    We review the emerging field of organic spintronics, where organic materials are applied as a medium to transport and control spin-polarized signals. The contacts for injecting and detecting spins are formed by ferromagnetic metals, oxides, or inorganic semiconductors. First, the basic concepts of spintronics and organic electronics are addressed, and phenomena which are in particular relevant for organic spintronics are highlighted. Experiments using different organic materials, including carbon nanotubes, organic thin films, self-assembled monolayers and single molecules are then reviewed. Observed magnetoresistance points toward successful spin injection and detection, but spurious magnetoresistance effects can easily be confused with spin accumulation. A few studies report long spin relaxation times and lengths, which forms a promising basis for further research. We conclude with discussing outstanding questions and problems. (topical review)

    Organic aerosols scatter solar radiation. They may also either enhance or decrease concentrations of cloud condensation nuclei. This paper summarizes observed concentrations of aerosols in remote continental and marine locations and provides estimates for the sources of organic aerosol matter. The anthropogenic sources of organic aerosols may be as large as the anthropogenic sources of sulfate aerosols, implying a similar magnitude of direct forcing of climate. The source estimates are highly uncertain and subject to revision in the future. A slow secondary source of organic aerosols of unknown origin may contribute to the observed oceanic concentrations. The role of organic aerosols acting as cloud condensation nuclei (CCN) is described and it is concluded that they may either enhance or decrease the ability of anthropogenic sulfate aerosols to act as CCN

    This chapter describes the technical approach, complicating factors, and sensitivities and uncertainties of calculations of doses to the organs of the A-bomb survivors. It is the object of the effort so described to provide data that enables the dosimetry system to determine the fluence, kerma, absorbed dose, and similar quantities in 14 organs and the fetus, specified as being of radiobiological interest. This object was accomplished through the use of adjoint Monte Carlo computations, which use a number of random particle histories to determine the relationship of incident neutrons and gamma rays to those transported to a target organ. The system uses these histories to correlate externally-incident energy- and angle-differential fluences with the fluence spectrum (energy differential only) within the target organ. In order for the system to work in the most efficient manner possible, two levels of data were provided. The first level, represented by approximately 6,000 random adjoint-particle histories, enables the computation of the fluence spectrum with sufficient precision to provide statistically reliable (± 6 %) mean doses within any given organ. With this limited history inventory, the system can be run rapidly for all survivors. Mean organ dose and dose uncertainty are obtainable in this mode. The second mode of operation enables the system to produce a good approximation to fluence spectrum within any organ or to produce the dose in each of an array of organ subvolumes. To be statistically reliable, this level of detail requires far more random histories, approximately 40,000 per organ. Thus, operation of the dosimetry system in this mode (i.e., with this data set) is intended to be on an as-needed, organ-specific basis, since the system run time is eight times that in the mean dose mode.

    1989-01-01

    The American organ procurement system has improved and matured in the last five years. At the same time, the basic challenges facing it have remained substantially the same because the moral and legal framework of the system has not changed. Success at organ procurement continues to depend on the voluntary cooperation of medical professionals and the families of potential organ donors. The generosity of the American public is so great that the primary challenge facing organ procurement agencies is obtaining cooperation from hospitals and medical professionals. This calls for a "marketing" orientation aimed at those hospitals and professionals who are most likely to treat potential donors. The last five years have seen a more general acceptance of this appreciation of the central task of organ procurement. As a result, the overall effectiveness of the system has improved, as measured by the number of organs procured on a per capita basis and by the number of multiorgan donors obtained. Much of this improvement can be attributed to the diffusion of organizational techniques and approaches, and this diffusion has been encouraged by the involvement of national organizations and public bodies in the organ procurement community. The system remains uneven in its effectiveness and further improvement is possible. It is also possible that the next general round of improvement will result from the application of businesslike information management and marketing techniques.

    Full Text Available One of the most used buzz-words in (e-business literature of the last decade is virtual organization. The term "virtual" can be identified in all sorts of combinations regarding the business world. From virtual products to virtual processes or virtual teams, everything that is “touched” by the computer’s processing power instantly becomes virtual. Moreover, most of the literature treats virtual and network organizations as being synonyms. This paper aims to draw a much more distinctive line between the two concepts. Providing a more coherent description of what virtual organization might be is also one of our intentions.

    Research has been fighting against organ failure and shortage of donations by supplying artificial organs for many years. With the raise of new technologies, tissue engineering and regenerative medicine, many organs can benefit of an artificial equivalent: thanks to retinal implants some blind people can visualize stimuli, an artificial heart can be proposed in case of cardiac failure while awaiting for a heart transplant, artificial larynx enables laryngectomy patients to an almost normal life, while the diabetic can get a glycemic self-regulation controlled by smartphones with an artificial device. Dialysis devices become portable, as well as the oxygenation systems for terminal respiratory failure. Bright prospects are being explored or might emerge in a near future. However, the retrospective assessment of putative side effects is not yet sufficient. Finally, the cost of these new devices is significant even if the advent of three dimensional printers may reduce it. © 2017 médecine/sciences – Inserm.

    Organic Computing is a research field emerging around the conviction that problems of organization in complex systems in computer science, telecommunications, neurobiology, molecular biology, ethology, and possibly even sociology can be tackled scientifically in a unified way. From the computer science point of view, the apparent ease in which living systems solve computationally difficult problems makes it inevitable to adopt strategies observed in nature for creating information processing machinery. In this book, the major ideas behind Organic Computing are delineated, together with a sparse sample of computational projects undertaken in this new field. Biological metaphors include evolution, neural networks, gene-regulatory networks, networks of brain modules, hormone system, insect swarms, and ant colonies. Applications are as diverse as system design, optimization, artificial growth, task allocation, clustering, routing, face recognition, and sign language understanding.

    Full Text Available L’article fait ressortir les marques linguistiques et extralinguistiques, sur lesquelles jouent certains journaux bulgaressoit pour rendre fiable une rumeur qu’ils relatent, tout en prenant prudemment leurs distances, soit pour ébranler la crédibilité d’un dit. Dans les deux cas la stratégie est la même: mélange d’indices qui vont dans les sens opposés, et, en fonction de l’effet recherché, ce sont soit celles qui valident la vérité du dit, soit celles qui le mettent en doute qui prédominent. Ce jeu permet aux journalistes de prendre part au jeu politique, d’orienter l’opinion publique, sans courir pour autant aucun risque. This paper analyzes the extralinguistic and linguistic features used by some Bulgarian newspapers, either for authenticating rumour or to undermine the credibility of the reported words. In both cases the same strategy is being used: Journalists mix up contradictory features. According to the effects they are striving for, either those, which validate the truthfulness of the reported words or those, which cast doubt on them are getting the upper hand. This ambiguity offers journalists protection against any accusation. Furthermore, it allows them to take part in political games and direct public opinion, without taking any risk.

    The category and objective of DFM production management are shown. DFM is not limited to an activity within a particular unit process in design and process. A new framework for DFM is required. DFM should be a total solution for the common problems of all processes. Each of them must be linked to one another organically. After passing through the whole of each process on the manufacturing platform, quality of final products is guaranteed and products are shipped to the market. The information platform is layered with DFM, APC, and AEC. Advanced DFM is not DFM for partial optimization of the lithography process and the design, etc. and it should be Organized DFM. They are managed with high-level organizational IQ. The interim quality between each step of the flow should be visualized. DFM will be quality engineering if it is Organized DFM and common metrics of the quality are provided. DFM becomes quality engineering through effective implementation of common industrial metrics and standardized technology. DFM is differential technology, but can leverage standards for efficient development.

    We present the experimental evidences for the existence of a superconducting state in the Quasi One Dimensional organic conductor (TMTSF) 2 PF 6 . Superconductivity occuring at 1 K under 12 kbar is characterized by a zero resistance diamagnetic state. The anistropy of the upper critical field of this type II superconductor is consistent with the band structure anistropy. We present evidences for the existence of large superconducting precursor effects giving rise to a dominant paraconductive contribution below 40 K. We also discuss the anomalously large pressure dependence of T sb(s), which drops to 0.19 K under 24 kbar in terms of the current theories. (author)

    Energy inflation, the constant encouragement to economize on energy consumption and the huge investments in developing alternative energy resources might seem to suggest that there is a global shortage of energy. Far from it, the energy the Sun beams on the Earth each hour is equivalent to a year's supply, even at our increasingly ravenous rate of global energy consumption [1]. But it's not what you have got it's what you do with it. Hence the intense focus on photovoltaic research to find more efficient ways to harness energy from the Sun. Recently much of this research has centred on organic solar cells since they offer simple, low-cost, light-weight and large-area flexible photovoltaic structures. This issue with guest editors Frederik C Krebs and Hongzheng Chen focuses on some of the developments at the frontier of organic photovoltaic technology. Improving the power conversion efficiency of organic photovoltaic systems, while maintaining the inherent material, economic and fabrication benefits, has absorbed a great deal of research attention in recent years. Here significant progress has been made with reports now of organic photovoltaic devices with efficiencies of around 10%. Yet operating effectively across the electromagnetic spectrum remains a challenge. 'The trend is towards engineering low bandgap polymers with a wide optical absorption range and efficient hole/electron transport materials, so that light harvesting in the red and infrared region is enhanced and as much light of the solar spectrum as possible can be converted into an electrical current', explains Mukundan Thelakkat and colleagues in Germany, the US and UK. In this special issue they report on how charge carrier mobility and morphology of the active blend layer in thin film organic solar cells correlate with device parameters [2]. The work contributes to a better understanding of the solar-cell characteristics of polymer:fullerene blends, which form the material basis for some of the most

    Full Text Available Rho-kinase and GTP-ase Rho are important regulators of vascular tone and blood pressure. The aim of this study was to investigate the role of Rho-kinase in artery reactions induced by angiotensin II (ANG II and the effects of ischemia-reperfusion injury as well as the function of intra- and extracellular calcium in these reactions. Experiments were performed on mesenteric superior arteries procured from cadaveric organ donors and conserved under the same conditions as transplanted kidneys. The vascular contraction in reaction to ANG II was measured in the presence of Rho-kinase inhibitor Y-27632, after ischemia and reperfusion, in Ca2+ and Ca2+-free solution. The maximal response to ANG II was reduced after ischemia, while an increase was observed after reperfusion. Vascular contraction induced by ANG II was decreased by Y-27632. Y-27632 reduced vascular contraction after reperfusion, both in Ca2+ and Ca2+-free solution. Reperfusion augments vascular contraction in reaction to ANG II. The Rho-kinase inhibitor Y-27632 reduces the hypersensitivity to ANG II after reperfusion mediated by both intra- and extracellular calcium. These results confirm the role of Rho-kinase in receptor-independent function of ANG II and in reperfusion-induced hypersensitivity.

    Full Text Available The purpose of the study was to explore differences between dairy cattle farmers in Bulgaria, according to certain factors. Information about the social characteristics of the farmers (educational level, gender, and age, and about the farm characteristics (number of cows in the main herd, average milk yield, and the rate of return on investment was collected. Sixty percent of the farmers were up to 50 years of age. Fifty percent of the farmers had had a secondary education and the rest had gained a university degree. The study found that only one of the 20 farmers was a woman. It was found that the group of farmers with a university degree had lower average age than the group of farmers with secondary school. There was no significant difference in the rate of return between the two groups of farms in terms of the effectiveness of the farm. The difference in the number of cows in the main herd was not significant too. The research identified a need for additional training for farmers in order to reduce their dependence on hired workers. It was found that farmers attend basic courses in the field of agriculture and livestock breeding in order to fill the gap between the existing levels of knowledge of farmers and the necessary skills for the effective management of dairy farms.

    Full Text Available We present a 55-year-old male patient - a smoker, admitted to a Medical Institute of MVR (Ministry of the interior, Sofia, Bulgaria, on occasion of pain and swellings, located in the area of both axillae, accompanied by purulent discharge, with bloody admixtures. Bilateral localised cystic rose above the skin surface, hyperpigmented nodules interconnected with multiple fistulas, was observed within the dermatological examination, resulting in a limitation of the possibility of movement of the hands in all directions. A subjective complaint of pain was obtained on palpation. Solid bilateral axillar cicatrices - formation was also established, which additional impeded the movements of the upper limbs. The disease was generalised affecting additional inguinal, femoral and perineal areas, while at this stage the patient refused categorically eventual photo documentation of them. The diagnosis of acne inversa was made based on the available clinical and para-clinical data, as dual antibiotic therapy with Clindamycin 300 mg, two times per day was initiated for two months, in combination with rifampicin 300 mg, two times per day also for two months. This led to a significant improvement in the clinic symptoms and the patient was hospitalised for radical surgery. A surgical management of the clinical findings was planned by an interdisciplinary team including surgeons and dermatologists. The procedure was performed under general anaesthesia. After a thorough cleaning of the operative field, a radical excision of the lesion in the left axillary and para axillar region was performed, comprising the skin and subcutaneous tissue forward the fascia pectoralis. Tissue was dissected in depth in the form of number 4, thereby creating the conditions for adaptation of the initially encountered communicating with each other skin defects. Two tubular drains were placed, followed by gradual suturing of skin and subcutaneous tissue with final applying of a sterile dressing. Effective medical treatment of patients (as in our case with severe AI is limited. Adalimumab is the first biological approved for moderate to severe AI but does not result in stable CR (cure rate. Therefore its use in a neoadjuvant setting is under investigation. Wide local excision significantly reduces pain and improves the quality of life of AI patients. While local recurrences rate is low, the satisfaction with the cosmetic results is high. The recurrence rate is dependent on the region affected and the type of surgery. While in the axillary region primary closure may be used to reduce the time to healing, anogenital AI has the lowest recurrence rate of healing by secondary intention.

    Full text: Poultry biodiversity conservation is a great challenge for many countries. Within the last several years, the number of endangered local breeds has increased, leading to a considerable loss of genetic resources. A similar trend was observed among the poultry breeds, including chicken, local turkey and goose breeds/lines established in Bulgaria, part of which is definitely lost. Currently these breeds/lines are at risk and/or threatened with extinction. The information obtained by phenotypic characterization of these breeds is the first step for planning the management of poultry genetic resources through setting up improved selection schemes and conservation strategies. In this paper, we reviewed the current state of knowledge regarding the morphological and phenotypic diversity of local poultry breeds and some old productive poultry lines in Bulgaria. (author)

    Full Text Available In 2013, the Fourth and Seventh Directives were replaced by a new Accounting Directive – Directive 2013/34/EC. The Directive is the outcome of EU aspirations to ease the business environment of small and medium-sized enterprises by simplifying the requirements with regard to reporting and mandatory disclosures for that category of enterprises. The entities of the practical sector (public and private limited liability companies, partnerships, general partnerships, etc. come within the scope of the Directive. The scope of the Directive excludes non-profit legal entities. The provisions of the Directive should, for the first time, be applied with regard to financial statements for reporting years beginning on or after January 1, 2016. Being an EC Member State, the Republic of Bulgaria has to transpose the Directive into the national accounting legislation by July 2015. The emphasis in this article is put on the basic problematic areas which occur in the process of the transposition of the Directive. As the possible solutions are based on established traditions and practices, the authors of this article try to identify the solutions to these problems taking into consideration the requirements imposed by the Directive itself. Four principal prob-lems are defined in the article: should there be a new Accounting Law and what should it include; should the Accounting Law include accounting principles; what groups and categories of enterprises should be differentiated and which accounting basis should be applied by any of them.

    For selected districts in the country, mean annual atmospheric precipitation rates were related to strontium-90 contents in milk over the period 1970-1977. Strontium-90 in milk was determined by the method of Popov, using Va-Z-310 counters for activity measurements. The impact of annual precipitation means was examined by monofactorial spread analysis, with sites distributed into three groups according to precipitation rates observed over longer time periods: up to 650 l/m 2 from 650 to 750 l/m 2 ; and above 750 L/M 2 . Values of coefficient F were estimated, representing the ratio of group to random spreads. These figures were compared with critical values in Student's tables for 0.05 significance level. The F data indicated a definite alternative relationship to exist between strontium-90 amounts in mils and annual precipitation rates, which is prognostically meaningful from the strandpoint of radiological protection of the population

    1993-01-01

    The structure of the national energy economy of Bulgaria implies characteristic features that specify low efficiency as regards power production, ecology and economics. Even the qualitative assessments show that these indices stand far away from the standards established in developed countries like Denmark, Finland, Sweden, etc. The best starting position for harmful energy efficiency improvement as well as emission reduction must be based on the restructuring of energy economy. The strategy of restructuring and development of energy economy covers the whole integrated national energy flow system 'resources - end user'. The preliminary study shows that energy efficiency can be increased by 25-30% within a period of 6-10 years using the least-cost investment strategy (including the research and development activities expenses). The study covers the existing structure of energy sector. Scenarios are being elaborated for its development and restructuring in respect to: heat production and transfer; electricity generation and transmission; energy consumption and conservation in residential buildings, public buildings and commercial sector; energy consumption in transport sector and agriculture. The approach for identification of the real potential opportunities in relation to the above stated areas is based on mathematical statistics and stochastic differential equations, multicriterial assessments, approach of self organisation systems and demand-side management.

  19. Organ mass measurements

    International Nuclear Information System (INIS)

    Kawamura, H.

    1998-01-01

    The term, anatomical measurements, in the context of this Co-ordinated Research Programme refers to measurements of masses of internal organs, although the human body is composed of internal organs and tissues such as skeleton, muscle, skin and adipose. The mass of an organ containing a radionuclide (source organ), and the mass of a target organ which absorbs energy of the radiation, are essential parameters in the ICRP dosimetric model derived from the MIRD method. Twelve specific organs of interest were proposed at the Coordinated Research Programme Project Formulation Meeting (PFM) in 1988. A slightly different set of thirteen organs with potential significance for radiation protection were selected for study at the Research Co-ordination Meeting held at the Bhabha Atomic Research Centre in 1991. The dimensions of the organs could also be useful information, but were considered unimportant for internal dose assessment. Due to the strong concern about the unified method for collecting organ mass data at the PFM, a guide-line was established stressing the need for organ data from subjects that were healthy and normal, at least until shortly before death, or from sudden death cases, following the Japanese experience. In this report, masses of nine to thirteen organs are presented from seven participating countries. Three participants have also reported the organ masses as fractions of the total body mass

  2. Organic 'Plastic' Optoelectronic Devices

    International Nuclear Information System (INIS)

    Sariciftci, N.S.

    2006-01-01

    Recent developments on conjugated polymer based photovoltaic diodes and photoactive organic field effect transistors (photOFETs) are discussed. The photophysics of such devices is based on the photoinduced charge transfer from donor type semiconducting conjugated polymers onto acceptor type conjugated polymers or acceptor molecules such as Buckminsterfullerene, C 6 0. Potentially interesting applications include sensitization of the photoconductivity and photovoltaic phenomena as well as photoresponsive organic field effect transistors (photOFETs). Furthermore, organic polymeric/inorganic nanoparticle based 'hybrid' solar cells will be discussed. This talk gives an overview of materials' aspect, charge-transport, and device physics of organic diodes and field-effect transistors. Furthermore, due to the compatibility of carbon/hydrogen based organic semiconductors with organic biomolecules and living cells there can be a great opportunity to integrate such organic semiconductor devices (biOFETs) with the living organisms. In general the largely independent bio/lifesciences and information technology of today, can be thus bridged in an advanced cybernetic approach using organic semiconductor devices embedded in bio-lifesciences. This field of bio-organic electronic devices is proposed to be an important mission of organic semiconductor devices

  4. Immunity of international organizations

    CERN Document Server

    Schrijver, Nico

    2015-01-01

    Immunity rules are part and parcel of the law of international organizations. It has long been accepted that international organizations and their staff need to enjoy immunity from the jurisdiction of national courts. However, it is the application of these rules in practice that increasingly causes controversy. Claims against international organizations are brought before national courts by those who allegedly suffer from their activities. These can be both natural and legal persons such as companies. National courts, in particular lower courts, have often been less willing to recognize the immunity of the organization concerned than the organization s founding fathers. Likewise, public opinion and legal writings frequently criticize international organizations for invoking their immunity and for the lack of adequate means of redress for claimants. It is against this background that an international conference was organized at Leiden University in June 2013. A number of highly qualified academics and practit...

    Organic field-effect transistors hold the promise of enabling low-cost and flexible electronics. Following its success in organic optoelectronics, the organic doping technology is also used increasingly in organic field-effect transistors. Doping not only increases device performance, but it also provides a way to fine-control the transistor behavior, to develop new transistor concepts, and even improve the stability of organic transistors. This Review summarizes the latest progress made in the understanding of the doping technology and its application to organic transistors. It presents the most successful doping models and an overview of the wide variety of materials used as dopants. Further, the influence of doping on charge transport in the most relevant polycrystalline organic semiconductors is reviewed, and a concise overview on the influence of doping on transistor behavior and performance is given. In particular, recent progress in the understanding of contact doping and channel doping is summarized.

  7. Focus on Organic Conductors

    Directory of Open Access Journals (Sweden)

    2009-01-01

    Full Text Available Organic materials are usually thought of as electrical insulators. Progress in chemical synthesis, however, has brought us a rich variety of conducting organic materials, which can be classified into conducting polymers and molecular crystals. Researchers can realize highly conducting molecular crystals in charge-transfer complexes, where suitable combinations of organic electron donor or acceptor molecules with counter ions or other organic molecules provide charge carriers. By means of a kind of chemical doping, the charge-transfer complexes exhibit high electrical conductivity and, thanks to their highly crystalline nature, even superconductivity has been observed. This focus issue of Science and Technology of Advanced Materials is devoted to the research into such 'organic conductors'The first organic metal was (TTF(TCNQ, which was found in 1973 to have high conductivity at room temperature and a metal–insulator transition at low temperatures. The first organic superconductor was (TMTSF2PF6, whose superconductivity under high pressures was reported by J´erome in 1980. After these findings, the research on organic conductors exploded. Hundreds of organic conductors have been reported, among which more than one hundred exhibit superconductivity. Recently, a single-component organic conductor has been found with metallic conductivity down to low temperatures.In these organic conductors, in spite of their simple electronic structures, much new physics has arisen from the low dimensionality. Examples are charge and spin density waves, characteristic metal–insulator transitions, charge order, unconventional superconductivity, superconductor–insulator transitions, and zero-gap conductors with Dirac cones. The discovery of this new physics is undoubtedly derived from the development of many intriguing novel organic conductors. High quality single crystals are indispensable to the precise measurement of electronic states.This focus issue

  8. Organically bound tritium

    International Nuclear Information System (INIS)

    Diabate, S.; Strack, S.

    1993-01-01

    Tritium released into the environment may be incorporated into organic matter. Organically bound tritium in that case will show retention times in organisms that are considerably longer than those of tritiated water which has significant consequences on dose estimates. This article reviews the most important processes of organically bound tritium production and transport through food networks. Metabolic reactions in plant and animal organisms with tritiated water as a reaction partner are of great importance in this respect. The most important production process, in quantitative terms, is photosynthesis in green plants. The translocation of organically bound tritium from the leaves to edible parts of crop plants should be considered in models of organically bound tritium behavior. Organically bound tritium enters the human body on several pathways, either from the primary producers (vegetable food) or at a higher tropic level (animal food). Animal experiments have shown that the dose due to ingestion of organically bound tritium can be up to twice as high as a comparable intake of tritiated water in gaseous or liquid form. In the environment, organically bound tritium in plants and animals is often found to have higher specific tritium concentrations than tissue water. This is not due to some tritium enrichment effects but to the fact that no equilibrium conditions are reached under natural conditions. 66 refs

    An "organizer" is formally defined as a region, or group of cells in an embryo that can both induce (change the fate) and pattern (generate an organized set of structures) adjacent embryonic cells. To date, about four such regions have been demonstrated: the primary or Spemann organizer (Hensen's node in amniotes), the notochord, the zone of polarizing activity of the limb bud, and the mid-hindbrain boundary. Here we review the evidence for these and compare them with a few other regions which have been proposed to represent other organizers and we speculate on why so few such regions have been discovered. © 2016 Elsevier Inc.

Complex organic solids, called tholins, produced by irradiation of the simulated Titanian atmosphere, are consistent with measured properties of Titan from ultraviolet to microwave frequencies and are the likely main constituents of the observed red aerosols. The tholins contain many of the organic building blocks central to life on earth. At least 100-m, and possibly kms thicknesses of complex organics have been produced on Titan during the age of the solar system, and may exist today as submarine deposits beneath an extensive ocean of simple hydrocarbons.

  10. Soil organic matter

    International Nuclear Information System (INIS)

    1976-01-01

    The nature, content and behaviour of the organic matter, or humus, in soil are factors of fundamental importance for soil productivity and the development of optimum conditions for growth of crops under diverse temperate, tropical and arid climatic conditions. In the recent symposium on soil organic matter studies - as in the two preceding ones in 1963 and 1969 - due consideration was given to studies involving the use of radioactive and stable isotopes. However, the latest symposium was a departure from previous efforts in that non-isotopic approaches to research on soil organic matter were included. A number of papers dealt with the behaviour and functions of organic matter and suggested improved management practices, the use of which would contribute to increasing agricultural production. Other papers discussed the turnover of plant residues, the release of plant nutrients through the biodegradation of organic compounds, the nitrogen economy and the dynamics of transformation of organic forms of nitrogen. In addition, consideration was given to studies on the biochemical transformation of organic matter, characterization of humic acids, carbon-14 dating and the development of modern techniques and their impact on soil organic matter research

    The paper is based on research conducted for DARCOF II (Danish Research Centre for Organic Farming, www.darcof.dk). The aim of the research project is to analyze the future development of the Danish organic food sector through focusing on two agro-commodities: vegetables and pork. Emphasis...... is placed on identification of economic forces within the supply chains. The main conclusions of the paper – being the results from the organic vegetable chain – are that the rules and regulations, and the development of alternative transaction processes in organic food and farming have so far been founded...... conventional farmers – declining prices, concentration of production and shift in bargaining power to the retailers. Logically, this situation will lead eventually to increasing conflicts between organic values and their subordination to free market forces, i.e. conventionalization. In the same time retailers...

    2003-05-01

    Nowadays artificial devices are not able to totally and undefinitely replace the loss of function of all vital organs and artificial organs can be used only to bridge the time to transplantation, which must be considered the first choice in the therapeutical approach for many chronic diseases. Since general population aging process is leading to an increase of organ demand, the gap between performed and requested transplantation is hard to fill. Xenotransplantation is nowadays only an experimental alternative solution and we have to do our best using available artificial organs to increase and improve the survival of patients waiting for transplantation. In this meeting we particularly dealt about organ function replacing therapy, especially regarding the kidney, heart, liver, pancreas and ear.

    Wang, Chengliang; Dong, Huanli; Jiang, Lang; Hu, Wenping

    2018-01-22

    Organic semiconductors have attracted a lot of attention since the discovery of highly doped conductive polymers, due to the potential application in field-effect transistors (OFETs), light-emitting diodes (OLEDs) and photovoltaic cells (OPVs). Single crystals of organic semiconductors are particularly intriguing because they are free of grain boundaries and have long-range periodic order as well as minimal traps and defects. Hence, organic semiconductor crystals provide a powerful tool for revealing the intrinsic properties, examining the structure-property relationships, demonstrating the important factors for high performance devices and uncovering fundamental physics in organic semiconductors. This review provides a comprehensive overview of the molecular packing, morphology and charge transport features of organic semiconductor crystals, the control of crystallization for achieving high quality crystals and the device physics in the three main applications. We hope that this comprehensive summary can give a clear picture of the state-of-art status and guide future work in this area.

  20. Organ donations after death

    2003-09-01

    Full Text Available The paper discusses public opinion on post-mortem organ donation, especially the difference between high support of public opinion to transplant activity, its general readiness to donate organs and the low number of signed organ donor cards. Through different approaches the article tries to point out possible factors relevant to the decision to donate organs. Early studies showed demographic variables and information as significant factors when deciding to donate organs after death. As there was not enough evidence that long-term effect through these factors is significant, the need for new investigation has grown. Social cognition theories helped understanding the difference mentioned above. It seems that the use of this approach might contribute to the understanding the problem and to delimit most useful factors when working with public.

  1. Self-organizing plasmas

    International Nuclear Information System (INIS)

    Hayashi, T.; Sato, T.

    1999-01-01

    The primary purpose of this paper is to extract a grand view of self-organization through an extensive computer simulation of plasmas. The assertion is made that self-organization is governed by three key processes, i.e. the existence of an open complex system, the existence of information (energy) sources and the existence of entropy generation and expulsion processes. We find that self-organization takes place in an intermittent fashion when energy is supplied continuously from outside. In contrast, when the system state is suddenly changed into a non-equilibrium state externally, the system evolves stepwise and reaches a minimum energy state. We also find that the entropy production rate is maximized whenever a new ordered structure is created and that if the entropy generated during the self-organizing process is expelled from the system, then the self-organized structure becomes more prominent and clear.

    The understanding and applications of organic semiconductors have shown remarkable progress in recent years. This material class has been developed from being a lab curiosity to the basis of first successful products as small organic LED (OLED) displays; other areas of application such as OLED lighting and organic photovoltaics are on the verge of broad commercialization. Organic semiconductors are superior to inorganic ones for low-cost and large-area optoelectronics due to their flexibility, easy deposition, and broad variety, making tailor-made materials possible. However, electrical doping of organic semiconductors, i.e. the controlled adjustment of Fermi level that has been extremely important to the success of inorganic semiconductors, is still in its infancy. This review will discuss recent work on both fundamental principles and applications of doping, focused primarily to doping of evaporated organic layers with molecular dopants. Recently, both p- and n-type molecular dopants have been developed that lead to efficient and stable doping of organic thin films. Due to doping, the conductivity of the doped layers increases several orders of magnitude and allows for quasi-Ohmic contacts between organic layers and metal electrodes. Besides reducing voltage losses, doping thus also gives design freedom in terms of transport layer thickness and electrode choice. The use of doping in applications like OLEDs and organic solar cells is highlighted in this review. Overall, controlled molecular doping can be considered as key enabling technology for many different organic device types that can lead to significant improvements in efficiencies and lifetimes.

    2013-01-01

    Organizing is such a common activity that we often do it without thinking much about it. In our daily lives we organize physical things--books on shelves, cutlery in kitchen drawers--and digital things--Web pages, MP3 files, scientific datasets. Millions of people create and browse Web sites, blog, tag, tweet, and upload and download content of all media types without thinking "I'm organizing now" or "I'm retrieving now." This book offers a framework for the theory and practice of organizing that integrates information organization (IO) and information retrieval (IR), bridging the disciplinary chasms between Library and Information Science and Computer Science, each of which views and teaches IO and IR as separate topics and in substantially different ways. It introduces the unifying concept of an Organizing System--an intentionally arranged collection of resources and the interactions they support--and then explains the key concepts and challenges in the design and deployment of Organizing Systems in many do...

    1983-01-01

    A property which is commonplace in the brain but which has always been ignored in learning machines is the spatial order of the processing units. This order is clearly highly significant and in nature it develops gradually during the lifetime of the organism. It then serves as the basis for perceptual and cognitive processes, and memory, too. The spatial order in biological organisms is often believed to be genetically determined. It is therefore intriguing to learn that a meaningful and optimal spatial order is formed in an extremely simple self-organizing process whereby certain feature maps are formed automatically. 8 references.

    Organic semiconductors formed by epitaxial growth from small molecules such as the para-phenylenes or squaraines promise a vast application potential as the active ingredient in electric and optoelectronic devices. Their self-organization into organic nanowires or "nanofibers" adds a peculiar...... attribute, making them especially interesting for light generation in OLEDs and for light-harvesting devices such as solar cells. Functionalization of the molecules allows the customization of optical and electrical properties. However, aging of the wires might lead to a considerable decrease in device...... performance over time. In this study the morphological stability of organic nanoclusters and nanowires from the methoxy functionalized quaterphenylene, 4,4'''dimethoxy-1,1':4',1''4'',1'''-quaterphenylene (MOP4), is investigated in detail.

  12. Professionalism and nonprofit organizations.

    Science.gov (United States)

    Majone, G

    1984-01-01

    Many professionals prefer to work in nonprofit organizations, rather than in either for-profit or bureaucratic organizations. This preference suggests that nonprofits may be successful in reducing the tension between professional principles and institutional requirements. Professionals in for-profit organizations must submit to the control of a manager who is motivated to overrule them whenever their decisions come into conflict with the goal of profit maximization. Bureaucratic organizations stress predictability of results and adherence to rules as the overriding criteria of evaluation and control. This paper argues that nonprofits are on the whole superior from the point of view of professional ideology and practice. Thus, given a commitment to the values of professionalism, the preference for the nonprofit form becomes understandable, even without the usual assumptions about income-maximizing behavior.

    The worldwide demand for organ transplants far exceeds available donor organs. Consequently some patients die whilst waiting for a transplant. Synthetic alternatives are therefore imperative to improve the quality of, and in some cases, save people's lives. Advances in biomaterials have generated a range of materials and devices for use either outside the body or through implantation to replace or assist functions which may have been lost through disease or injury. Biomaterials for artificial organs reviews the latest developments in biomaterials and investigates how they can be used to improve the quality and efficiency of artificial organs. Part one discusses commodity biomaterials including membranes for oxygenators and plasmafilters, titanium and cobalt chromium alloys for hips and knees, polymeric joint-bearing surfaces for total joint replacements, biomaterials for pacemakers, defibrillators and neurostimulators and mechanical and bioprosthetic heart valves.

    Organic electrochemical transistors (OECTs) make effective use of ion injection from an electrolyte to modulate the bulk conductivity of an organic semiconductor channel. The coupling between ionic and electronic charges within the entire volume of the channel endows OECTs with high transconductance compared with that of field-effect transistors, but also limits their response time. The synthetic tunability, facile deposition and biocompatibility of organic materials make OECTs particularly suitable for applications in biological interfacing, printed logic circuitry and neuromorphic devices. In this Review, we discuss the physics and the mechanism of operation of OECTs, focusing on their identifying characteristics. We highlight organic materials that are currently being used in OECTs and survey the history of OECT technology. In addition, form factors, fabrication technologies and applications such as bioelectronics, circuits and memory devices are examined. Finally, we take a critical look at the future of OECT research and development.

  3. Underfunding in Terrorist Organizations

    Science.gov (United States)

    Shapiro, Jacob N.; Siegel, David A.

    A review of international terrorist activity reveals a pattern of financially strapped operatives working for organizations that seem to have plenty of money. To explain this observation, and to examine when restricting terrorists’ funds will reduce their lethality, we model a hierarchical terror organization in which leaders delegate financial and logistical tasks to middlemen, but cannot perfectly monitor them for security reasons. These middlemen do not always share their leaders’ interests: the temptation exists to skim funds from financial transactions. When middlemen are sufficiently greedy and organizations suffer from sufficiently strong budget constraints, leaders will not fund attacks because the costs of skimming are too great. Using general functional forms, we find important nonlinearities in terrorists’ responses to government counter-terrorism. Restricting terrorists’ funds may be ineffective until a critical threshold is reached, at which point cooperation within terrorist organizations begins to break down and further government actions have a disproportionately large impact.

    Astronomical observations, theoretical modeling, laboratory simulation and analysis of extraterrestrial material have enhanced our knowledge of the inventory of organic matter in the interstellar medium (ISM) and on small bodies such as comets and asteroids (Ehrenfreund & Charnley 2000). Comets, asteroids and their fragments, meteorites and interplanetary dust particles (IDPs), contributed significant amounts of extraterrestrial organic matter to the young Earth. This material degraded and reacted in a terrestrial prebiotic chemistry to form organic structures that may have served as building blocks for life on the early Earth. In this talk I will summarize our current understanding of the organic composition and chemistry of interstellar clouds. Molecules of astrobiological relevance include the building blocks of our genetic material: nucleic acids, composed of subunits such as N-heterocycles (purines and pyrimidines), sugars and amino acids. Signatures indicative of inheritance of pristine and modified interstellar material in comets and meteorites will also be discussed.

    2015-11-11

    Organic switching devices such as field effect transistors (OFETs) are a key element of future flexible electronic devices. So far, however, a commercial breakthrough has not been achieved because these devices usually lack in switching speed (e.g. for logic applications) and current density (e.g. for display pixel driving). The limited performance is caused by a combination of comparatively low charge carrier mobilities and the large channel length caused by the need for low-cost structuring. Vertical Organic Transistors are a novel technology that has the potential to overcome these limitations of OFETs. Vertical Organic Transistors allow to scale the channel length of organic transistors into the 100 nm regime without cost intensive structuring techniques. Several different approaches have been proposed in literature, which show high output currents, low operation voltages, and comparatively high speed even without sub-μm structuring technologies. In this review, these different approaches are compared and recent progress is highlighted.

    Carbonaceous meteorites are primitive samples from the asteroid belt, containing 3-5wt% organic carbon. The exogenous delivery of organic matter by carbonaceous meteorites may have contributed to the organic inventory of the early Earth. The majority (>70%) of the meteoritic organic material consist of insoluble organic matter (IOM) [1]. The remaining meteoritic organic material (meteorites contain soluble organic molecules with different abundances and distributions, which may reflect the extension of aqueous alteration or thermal metamorphism on the meteorite parent bodies. Extensive aqueous alteration on the meteorite parent body may result on 1) the decomposition of α-amino acids [5, 6]; 2) synthesis of β- and γ-amino acids [2, 6-9]; 3) higher relative abundances of alkylated polycyclic aromatic hydrocarbons (PAHs) [6, 10]; and 4) higher L-enantiomer excess (Lee) value of isovaline [6, 11, 12].The soluble organic content of carbonaceous meteorites may also have a contribution from Fischer-Tropsch/Haber-Bosch type gas-grain reactions after the meteorite parent body cooled to lower temperatures [13, 14].The analysis of the abundances and distribution of the organic molecules present in meteorites helps to determine the physical and chemical conditions of the early solar system, and the prebiotic organic compounds available on the early Earth.[1] Cody and Alexander (2005) GCA 69, 1085.

    Bare fallow soils that have been deprived of fresh carbon inputs for prolonged periods contain mostly old, stable organic carbon. In order to shed light on the nature of this carbon, the functional diversity profiles (MicroResp™, Biolog™ and enzyme activity spectra) of the microbial communities of long-term barefallow soils were analysed and compared with those of the microbial communities from their cultivated counterparts. The study was based on the idea that microbial communities adapt to their environment and that therefore the catabolic and enzymatic profiles would reflect the type of substrates available to the microbial communities. The catabolic profiles suggested that the microbial communities in the long-term bare-fallow soil were exposed to a less diverse range of substrates and that these substrates tended to be of simpler molecular forms. Both the catabolic and enzyme activity profiles suggested that the microbial communities from the long-term bare-fallow soils were less adapted to using polymers. These results do not fit with the traditional view of old, stable carbon being composed of complex, recalcitrant polymers. An energetics analysis of the substrate use of the microbial communities for the different soils suggested that the microbial communities from the long-term bare-fallow soils were better adapted to using readily oxidizable,although energetically less rewarding, substrates. Microbial communities appear to adapt to the deprivation of fresh organic matter by using substrates that require little investment.

    This article discusses the highly controversial question whether human organs should be allowed to be the object of a contract aimed at profit. The author comes to the conclusion that--seen from a consequentialist viewpoint--the legislature is not well-advised to allow organ donations for consideration. However, it is admitted that a more deontological approach could come to quite the opposite conclusion.

Feeding and breeding in conventional production are emerged some of the negative effects and also it is more in organic production with new restrictions. Organic production is based on animal welfare. On the basis of behaviors such as feather-pecking and cannibalism known to be low in protein level of rations and unbalanced in terms of amino acids or minerals. As of 2015, organic poultry feed provided the appropriate conditions that will be 95% organic certified in Turkey and therefore, to create a balanced ration and feed hygiene in protecting brings serious challenges. Fodder supply of organic poultry feed raw materials that make up the quality, quantity and issue forms a significant effect on the health of the poultry additives permitted. The quality of the feed raw materials that constituent diets, quantity, feed supplying form and permitted feed additives significantly affects the health of poultry. Different physiological stages of the animal's nutritional requirements in order to ensure production of quality poultry products must be met from organically produced and very well-known with the contents of feedstuff digestibility. In this study, the problems encountered in feeding can be eliminated while performing economic production with considering animal welfare, following that balanced and adequate organic ration formulations and issues such as improving the production of feed raw materials are discussed.

  3. Managing mechanistic and organic structure in health care organizations.

    Science.gov (United States)

    Olden, Peter C

    2012-01-01

    Managers at all levels in a health care organization must organize work to achieve the organization's mission and goals. This requires managers to decide the organization structure, which involves dividing the work among jobs and departments and then coordinating them all toward the common purpose. Organization structure, which is reflected in an organization chart, may range on a continuum from very mechanistic to very organic. Managers must decide how mechanistic versus how organic to make the entire organization and each of its departments. To do this, managers should carefully consider 5 factors for the organization and for each individual department: external environment, goals, work production, size, and culture. Some factors may push toward more mechanistic structure, whereas others may push in the opposite direction toward more organic structure. Practical advice can help managers at all levels design appropriate structure for their departments and organization.

    2004-01-01

    This article presents an overview of factors associated with thoracic transplantation outcomes over the past decade and provides valuable information regarding the heart, lung, and heart-lung waiting lists and thoracic organ transplant recipients. Waiting list and post-transplant information is used to assess the importance of patient demographics, risk factors, and primary cardiopulmonary disease on outcomes. The time that the typical listed patient has been waiting for a heart, lung, or heart-lung transplant has markedly increased over the past decade, while the number of transplants performed has declined slightly and survival after transplant has plateaued. Waiting list mortality, however, appears to be declining for each organ and for most diseases and high-severity subgroups, perhaps in response to recent changes in organ allocation algorithms. Based on perceived inequity in organ access and in response to a mandate from Health Resources and Services Administration, the lung transplant community is developing a lung allocation system designed to minimize deaths on the waiting list while maximizing the benefit of transplant by incorporating post-transplant survival and quality of life into the algorithm. Areas where improved data collection could inform evolving organ allocation and candidate selection policies are emphasized.

    The Republic of Kazakhstan is one of the fastest developing countries in the world and has a health care system that is unique in Central Asia. Its organ transplant services are also developing rapidly. We aimed to analyze and briefly report on the current status of organ transplant in the Republic of Kazakhstan. We analyzed organ transplant activities in that country for the period 2012 to 2014. All data were collected from the official database of the National Transplant Coordinating Center of the Republic of Kazakhstan. At the end of 2014, the number of transplant centers had increased to 10, three of which could perform multiorgan transplants; during the same period, the number of deceased-donor organ-donating hospitals increased up to 37. By 2013, the transplant activity rate for all centers had reached 9.22 per million population. During the previous 3 years (2012-2014), there was a 3-fold increase in the number of living donors and an 18-fold increase in the number of kidney transplants. Between 2012 and 2014, the number of living-donor liver transplants increased from 17 to 25, and the number of deceased-donor transplants increased from 3 to 7. During the last 3 years (2012-2014), the number of heart transplants increased to 7 cases. During the last 3 years (2012-2014), Kazakhstan achieved a significant improvement in the organization of its transplant services, and a noticeable upward trend in the system continues.

    2015-01-01

    International Organizations as Orchestrators reveals how IOs leverage their limited authority and resources to increase their effectiveness, power, and autonomy from states. By 'orchestrating' intermediaries - including NGOs - IOs can shape and steer global governance without engaging in hard, direct regulation. This volume is organized around a theoretical model that emphasizes voluntary collaboration and support. An outstanding group of scholars investigate the significance of orchestration across key issue areas, including trade, finance, environment and labor, and in leading organizations, including the GEF, G20, WTO, EU, Kimberley Process, UNEP and ILO. The empirical studies find that orchestration is pervasive. They broadly confirm the theoretical hypotheses while providing important new insights, especially that states often welcome IO orchestration as achieving governance without creating strong institutions. This volume changes our understanding of the relationships among IOs, nonstate actors and sta...

    2017-10-06

    The organization of microtubule networks is crucial for controlling chromosome segregation during cell division, for positioning and transport of different organelles, and for cell polarity and morphogenesis. The geometry of microtubule arrays strongly depends on the localization and activity of the sites where microtubules are nucleated and where their minus ends are anchored. Such sites are often clustered into structures known as microtubule-organizing centers, which include the centrosomes in animals and spindle pole bodies in fungi. In addition, other microtubules, as well as membrane compartments such as the cell nucleus, the Golgi apparatus, and the cell cortex, can nucleate, stabilize, and tether microtubule minus ends. These activities depend on microtubule-nucleating factors, such as γ-tubulin-containing complexes and their activators and receptors, and microtubule minus end-stabilizing proteins with their binding partners. Here, we provide an overview of the current knowledge on how such factors work together to control microtubule organization in different systems.

    Annesini, Maria Cristina; Piemonte, Vincenzo; Turchetti, Luca

    2017-01-01

    Artificial organs may be considered as small-scale process plants, in which heat, mass and momentum transfer operations and, possibly, chemical transformations are carried out. This book proposes a novel analysis of artificial organs based on the typical bottom-up approach used in process engineering. Starting from a description of the fundamental physico-chemical phenomena involved in the process, the whole system is rebuilt as an interconnected ensemble of elemental unit operations. Each artificial organ is presented with a short introduction provided by expert clinicians. Devices commonly used in clinical practice are reviewed and their performance is assessed and compared by using a mathematical model based approach. Whilst mathematical modelling is a fundamental tool for quantitative descriptions of clinical devices, models are kept simple to remain focused on the essential features of each process. Postgraduate students and researchers in the field of chemical and biomedical engineering will find that t...

  12. Phytovolatilization of Organic Contaminants.

    Science.gov (United States)

    Limmer, Matt; Burken, Joel

    2016-07-05

    Plants can interact with a variety of organic compounds, and thereby affect the fate and transport of many environmental contaminants. Volatile organic compounds may be volatilized from stems or leaves (direct phytovolatilization) or from soil due to plant root activities (indirect phytovolatilization). Fluxes of contaminants volatilizing from plants are important across scales ranging from local contaminant spills to global fluxes of methane emanating from ecosystems biochemically reducing organic carbon. In this article past studies are reviewed to clearly differentiate between direct- and indirect-phytovolatilization and we discuss the plant physiology driving phytovolatilization in different ecosystems. Current measurement techniques are also described, including common difficulties in experimental design. We also discuss reports of phytovolatilization in the literature, finding that compounds with low octanol-air partitioning coefficients are more likely to be phytovolatilized (log KOA < 5). Reports of direct phytovolatilization at field sites compare favorably to model predictions. Finally, future research needs are presented that could better quantify phytovolatilization fluxes at field scale.

    1979-01-01

    Features taken from various models of Titan's atmosphere are combined in a working composite model that provides environmental constraints within which different pathways for organic chemical synthesis are determined. Experimental results and theoretical modeling suggest that the organic chemistry of the satellite is dominated by two processes: photochemistry and energetic particle bombardment. Photochemical reactions of CH4 in the upper atmosphere can account for the presence of C2 hydrocarbons. Reactions initiated at various levels of the atmosphere by cosmic rays, Saturn 'wind', and solar wind particle bombardment of a CH4-N2 atmospheric mixture can account for the UV-visible absorbing stratospheric haze, the reddish appearance of the satellite, and some of the C2 hydrocarbons. In the lower atmosphere photochemical processes will be important if surface temperatures are sufficiently high for gaseous NH3 to exist. It is concluded that the surface of Titan may contain ancient or recent organic matter (or both) produced in the atmosphere.

    1994-01-01

    Studies of the molecular structures and C,N,H-isotopic compositions of organic matter in meteorites reveal a complex history beginning in the parent interstellar cloud which spawned the solar system. Incorporation of interstellar dust and gas in the protosolar nebula followed by further thermal and aqueous processing on primordial parent bodies of carbonaceous, meteorites have produced an inventory of diverse organic compounds including classes now utilized in biochemistry. This inventory represents one possible set of reactants for chemical models for the origin of living systems on the early Earth. Evidence bearing on the history of meteoritic organic matter from astronomical observations and laboratory investigations will be reviewed and future research directions discussed.

  17. Bioethics of organ transplantation.

    Science.gov (United States)

    Caplan, Arthur

    2014-03-01

    As the ability to transplant organs and tissues has grown, the demand for these procedures has increased as well--to the point at which it far exceeds the available supply creating the core ethical challenge for transplantation--rationing. The gap between supply and demand, although large, is worse than it appears to be. There are two key steps to gaining access to a transplant. First, one must gain access to a transplant center. Then, those waiting need to be selected for a transplant. Many potential recipients do not get admitted to a program. They are deemed too old, not of the right nationality, not appropriate for transplant as a result of severe mental impairment, criminal history, drug abuse, or simply because they do not have access to a competent primary care physician who can refer them to a transplant program. There are also financial obstacles to access to transplant waiting lists in the United States and other nations. In many poor nations, those needing transplants simply die because there is no capacity or a very limited capacity to perform transplants. Although the demand for organs now exceeds the supply, resulting in rationing, the size of waiting lists would quickly expand were there to suddenly be an equally large expansion in the number of organs available for transplantation. Still, even with the reality of unavoidable rationing, saving more lives by increasing organ supply is a moral good. Current public policies for obtaining organs from cadavers are not adequate in that they do not produce the number of organs that public polls of persons in the United States indicate people are willing to donate.

    2017-04-01

    Biochar produced in cost-efficient flame curtain kilns (Kon-Tiki) was nutrient enriched either with cow urine or with dissolved mineral (NPK) fertilizer to produce biochar-based fertilizers containing between 60-100 kg N, 5-60 kg P2O5 and 60-100 kg K2O, respectively, per ton of biochar. In 21 field trials nutrient-enriched biochars were applied at rates of 0.5 to 2 t ha-1 into the root zone of 13 different annual and perennial crops. Treatments combining biochar, compost and organic or chemical fertilizer were evaluated; control treatments contained the same amounts of nutrients but without biochar. All nutrient-enriched biochar substrates improved yields compared to their respective no-biochar controls. Biochar enriched with dissolved NPK produced on average 20% ± 5.1% (N=4) higher yields than standard NPK fertilization without biochar. Cow urine-enriched biochar blended with compost resulted on average in 123% ± 76.7% (N=13) higher yields compared to the organic farmer practice with cow urine-blended compost and outcompeted NPK-enriched biochar (same nutrient dose) by 103% ± 12.4% (N=4) on average. 21 field trials robustly revealed that low-dosage root zone application of organic biochar-based fertilizers caused substantial yield increases in rather fertile silt loam soils compared to traditional organic fertilization and to mineral NPK- or NPK-biochar fertilization. This can likely be explained by the nutrient carrier effect of biochar causing a slow nutrient release behavior, more balanced nutrient fluxes and reduced nutrient losses especially when liquid organic nutrients are used for the biochar enrichment. The results promise new pathways for optimizing organic farming and improving on-farm nutrient cycling.

  19. Organizations as Designed Islands

    Directory of Open Access Journals (Sweden)

    2009-05-01

    Full Text Available The literature and practice of organizational design are mostly based on simplistic conceptions which ignore recent theoretical developments in organizational studies. Conceiving of organizations as ‘designed islands’, it is argued, can contribute to a more solid theoretical foundation to organization theory, viewed as normative science. Relying on the work of Peter Sloterdijk, who describes the forms of life in space in terms of spheres, the heuristic power of the island metaphor is explored. What can be learnt from the art of isolating in order to construct lived organizational environments is then discussed, and the paradoxical relationship between connection and isolation is highlighted.

  7. Microwaves in organic chemistry and organic chemical

    Directory of Open Access Journals (Sweden)

    Mijin Dušan Ž.

    2005-01-01

    Full Text Available The usual way of applying heat to a chemical reaction is the use of a Bunsen burner, an oil or some other type of bath, or an electric heater. In inorganic chemistry, microwave technology has been used since the late 1970s while it has been implemented in organic chemistry since the mid-1980s. Microwave heating has been used in the food industry for almost fifty years. The shorter reaction times and expanded reaction range that is offered by microwave technology are suited to the increased demands in industry. For example, there is a requirement in the pharmaceutical industry for a higher number of a novel chemical entities to be produced, which requires chemists to employ a number of resources to reduce time for the production of compounds. Also, microwaves are used in the food industry, as well as in the pyrolysis of waste materials, sample preparation, the solvent extraction of natural products and the hydrolysis of proteins and peptides.

  6. ZOONOSIS OF AQUATICAL ORGANISMS

    Directory of Open Access Journals (Sweden)

    Božidar Kurtović

    2001-12-01

    Full Text Available Aquatic organisms play a very important role in human nutrition. They also pose a real threat for human health by causing various diseases. Parasites, bacteria and viruses may either directly or indirectly be carried from aquatic organisms to humans. Disease outbreaks are influenced by many factors among which decreased immune response and feeding habits and higyene are most important. More frequent occuence of foodborne diseases has a number of reasons, including international travel and trade, microbial adaptation and changes in the food production system. Parasitic diseases occur most frequently as a result of human role in parasites life cycles. The prevalence is further increased by consuming raw fish and shellfish. The main feature of bacterial infections is facultative pathogenicity of most ethiological agents. In most cases disease occures as a result of decreased immunoreactivity. Several bacteria are, however, hightly pathogenic and capable of causing high morbidity and mortality in human. To date it has not been reported the case of human infection with viruses specific for aquatic organisms. Human infections are caused with human viruses and aquatic organisms play role only as vechicles. The greatest risk in that respect present shellfish. Fish and particularly shellfish are likely to cause food poisoning in humans. In most cases the cause are toxins of phithoplancton origins accumulating in shellfish and fish.

    Lüssem, Björn; Günther, Alrun; Fischer, Axel; Kasemann, Daniel; Leo, Karl

    2015-01-01

    Organic switching devices such as field effect transistors (OFETs) are a key element of future flexible electronic devices. So far, however, a commercial breakthrough has not been achieved because these devices usually lack in switching speed (e.g. for logic applications) and current density (e.g. for display pixel driving). The limited performance is caused by a combination of comparatively low charge carrier mobilities and the large channel length caused by the need for low-cost structuring. Vertical Organic Transistors are a novel technology that has the potential to overcome these limitations of OFETs. Vertical Organic Transistors allow to scale the channel length of organic transistors into the 100 nm regime without cost intensive structuring techniques. Several different approaches have been proposed in literature, which show high output currents, low operation voltages, and comparatively high speed even without sub-μm structuring technologies. In this review, these different approaches are compared and recent progress is highlighted. (topical review)

    Directory of Open Access Journals (Sweden)

    Claro Llaguno

    2001-06-01

    Full Text Available Recent reports have brought to public attention concerns about Bt corn and genetically modified organisms (GMO in general. The timing, it seems, is most appropriate considering two related developments early this year: the final approval of the Cartagena Protocol on Biosafety in Montreal on January 29, 2001, and the OECD Edinburgh Conference on GM food safety last February 28- March 1, 2001. The protocol makes clear that GMOs include all living modified organisms (LMO defined as "any living organism that possesses a novel combination of genetic material obtained through the use of modern biotechnology". This includes seeds, live fish, and other organisms intentionally obtained for release to the environment. It would seem that the common understanding about GMOs as referring to farm-to-table products is perforce expanded to embrace genetically modified farm animals and aquatic resources. Being a trade agreement, the Montreal accord primarily deals with the safety issues related to the transboundary movement of LMOs around the globe. The OECD conference on the other hand, called for an international body "to address all sides of the GM debate" in response to the public outcry, particularly in Western Europe, regarding the risks the new products pose to human health and the environment. Some points of contention, which remain unresolved, include issues such as whether countries should be allowed to develop their own GM food based on their needs, and whether a global moratorium on GMOs and mandatory labeling should be enforced worldwide.

    1985-01-01

    Brookhaven National Laboratory has conducted a study on the need and feasibility of an independent organization to investigate significant safety events for the Office for Analysis and Evaluation of Operational Data, USNRC. The study consists of three parts: the need for an independent organization to investigate significant safety events, alternative organizations to conduct investigations, and legislative requirements. The determination of need was investigated by reviewing current NRC investigation practices, comparing aviation and nuclear industry practices, and interviewing a spectrum of representatives from the nuclear industry, the regulatory agency, and the public sector. The advantages and disadvantages of alternative independent organizations were studied, namely, an Office of Nuclear Safety headed by a director reporting to the Executive Director for Operations (EDO) of NRC; an Office of Nuclear Safety headed by a director reporting to the NRC Commissioners; a multi-member NTSB-type Nuclear Safety Board independent of the NRC. The costs associated with operating a Nuclear Safety Board were also included in the study. The legislative requirements, both new authority and changes to the existing NRC legislative authority, were studied. 134 references

  10. Organics In Meteorites

    Science.gov (United States)

    Chang, Sherwood

    1996-01-01

    The variety of classes of organic compounds that occur in carbonaceous meteorites suggests a rich pre-planetary chemistry with possible connections to interstellar, solar nebular and parent body processes. Structural diversity prevails within all classes examined in detail. Among amino acids for instance, all possible isomers are found up to species containing 4-6 carbon atoms, with abundances decreasing with increasing molecular weight. Such diversity seems limited to those carbonaceous meteorites which show evidence of having been exposed to liquid water; meteorites lacking such evidence also show much lower abundances and less structural diversity in their organic contents. This apparent dependency on water suggests a role for cometary ices in the chemical evolution of organic compounds on parent bodies. Measurements of the stable isotope compositions of C, H, N and S in classes of compounds and at the individual compound level show strong deviations from average chondritic values. These deviations are difficult to explain by solar system or parent body processes, and precedents for some of these isotopic anomalies exist in interstellar (e.g., high D/H ratios) and circumstellar chemistry. Therefore, presolar origins for much if not all of the meteoritic organic compounds (or their precursors) is a distinct possibility. In contrast, evidence of solar nebular origins is either lacking or suspect. Results from molecular and isotopic analyses of meteoritic organics, from laboratory simulations and from a model of interstellar grain reactions will be used to flesh out the hypothesis that this material originated with interstellar chemistry, was distributed within the early solar system as cometary ices, and was subsequently altered on meteorite parent bodies to yield the observed compounds.

  11. STRESS IN ORGANIZATIONS

    Maria-Elena, GHEORDUNESCU

    2014-11-01

    Full Text Available Taking into account the changes that are currently taking place in our country, it is clear that these changes, which occur in almost all companies, lead to new stress factors for both employees and the organization. Occupational stress is a major problem for employees and managers, but also for the whole society. The issue of stress in organizations has given birth to many debates and studies. It is a common theme that is addressed by managers, employees and consultants from different perspectives. According to a study by the European Agency for Safety and Health at Work, in the European Union, work-related stress is the second work-related health issue after dorsal disorders. It affects 28% of EU employees. The European Parliament is fully involved in addressing issues related to the psychological support of the staff. Preventing work-related stress is one of the objectives set out in the Communique of the European Commission for Employment and Social Affairs regarding their new health and safety at work strategy. Manifestations of stress in organizations are easily observable, being manifested by behaviors such as: difficulties in adapting to the changes required to work or the dramatic drop in labor productivity. Also a double action is met: both the person who passes through the stressful situation and at the organization level on which it is reflected the existence of a stressful environment. This paper aims to address the implications of workplace stress, symptoms of stress in the workplace and strategies to eliminate and prevent stress at work This paper represents an exploratory research based on qualitative methods, being consulted various sources of information: the literature, case studies, media articles, reports of relevant organizations, etc.

  12. The impact of quality department on organizing quality in organizations

    2016-06-01

    Full Text Available Research Question: The existence of organizations in competitive markets depends on their ability to stay competitive. Quality departments play a key role in organizing and ensuring quality. Purpose: The survey tries to determine the correlation between the existence of quality departments and organization of quality in organizations; our hypothesis is that the correlation is very strong. Method: A survey was performed in 484 large and medium-sized organizations in Slovenia to examine the situation in this area. Pearson's χ2-test was used for data processing and results presented in a contingency table. Results: Organizations with quality departments more frequently also have certificate ISO 9001 in comparison with organizations without quality departments. Also these organizations more frequently have supplier-relations teams, monitoring system of suppliers' progress and excellence centers. In short, the quality in these organizations is organized on a higher level than in organizations without quality departments. Organization: The role of quality department is important for organizations. The findings of the research are important for decision making in organizations. Society: Each organization contributes to efficiency and effectiveness of a nation. The organizational level of the nation can be measured by number of certificates per capita. Originality: The research is unique because of the research model and method applied. Limitations/Future Research: The research is limited to large and medium-sized organizations in Slovenia.

  13. Exploring network organization in practice

    DEFF Research Database (Denmark)

    Hu, Yimei; Sørensen, Olav Jull

    Constructing a network organization for global R&D is presented as a common sense practice in existing literature. However, there are still queries about the network organization, such as the persistence of hierarchies which make a network organization merely a “bureaucracy-lite” organization....... Furthermore, in practice, we rarely see radical organizational change towards a network organization that adopts an internal market. The co-existence of market, hierarchy and network triggered research interest. A multiple case study of three transnational corporations’ global R&D organization shows...... that there are different logical considerations when designing a network organization to facilitate innovation. I identify three types of network organizations: market-led, directed and culture-led network organizations. Different types of network organizations show that organizations are dual and even ternary systems...

    Matrix organization can provide health care organization managers enhanced information processing, faster response times, and more flexibility to cope with greater organization complexity and rapidly changing operating environments. A review of the literature informed by work experience reveals that the use of matrix organization creates hard-to-manage ambiguity and balances of power in addition to providing positive benefits for health care organization managers. Solutions to matrix operating problems generally rely on the use of superior information and decision support systems and extensive staff training to develop attitudes and behavior consistent with the more collegial matrix organization culture. Further improvement in understanding the suitability of matrix organization for managing health care delivery organizations will involve appreciating the impact of partial implementation of matrix organization, temporary versus permanent uses of matrix organization, and the impact of the ambiguity created by dual lines of authority upon the exercise of power and authority.

    To describe the current practice of pediatric organ donor management in the United States for donors declared dead based upon neurologic criteria. The study directs particular attention to how pediatric donors are defined, the use of donor management guidelines, the use of donor management goals, and the involvement of pediatric critical care or transplantation expertise. Cross-sectional observational study using a web-based survey and follow-up telephone interview with respondents from U.S. organ procurement organizations. The study also incorporated organ procurement organization-specific data on organ yield for the 4-year period (2010-2013) preceding the study. The 58 U.S. organ procurement organizations. Respondents chosen by each organ procurement organization. None. All 58 U.S. organ procurement organizations participated in the study. Fifty-two respondents (90%) indicated that their organ procurement organization distinguished pediatric from adult donors resulting in 28 unique pediatric definitions. Thirty-nine organ procurement organizations utilized some form of written pediatric management guidelines, and 27 (47%) maintained pediatric donor management goals; compliance was infrequently monitored for both guidelines (28%) and goals (33%). A pediatric intensivist was always or usually involved in pediatric donor management at 47 organ procurement organizations (81%); transplant/organ recovery surgeons were always or usually involved at 12 organ procurement organizations (21%). There was an increase in the number of organs transplanted per donor among donors 11-17 years old for organ procurement organizations that used donor management goals for the duration of the period studied (p procurement organizations that always or usually consulted a transplant/organ recovery surgeon (p = 0.02) although this did not reach our threshold for statistical significance.. There is little consensus among organ procurement organizations regarding the definition of

    Carbon is the element which makes up the major fraction of lipids and carbohydrates, which could be used for making biofuel. It is therefore important to provide enough carbon and also follow the flow into particulate organic carbon and potential loss to dissolved organic forms of carbon. Here we present methods for determining dissolved inorganic carbon, dissolved organic carbon, and particulate organic carbon.

    Invention relates with a new organism for the coal liquefying desulfurization. This micro-organism conducts a good sporulation on a culture medium which contains a coal as an only carbon source. It belongs to Penicillium and named Penicillium MT-6001 registered at Fermentation Research Institute No. 8463. Coal powder is thrown into a reaction vessel which accommodated a culture solution of this bacteria, and the surface of the solution is covered with liquid paraffin; coal powder is treated of liquefaction for about 5 hours while maintaining the anaerobic condition and slowly agitating to form a transparent solution layer on the surface of the reactor together with liquid paraffin. Liquefied product shows an analysis pattern similar to naphthenic petroleum containing a lipid with polar radical. (2 figs)

    Optical vortex beams are at the heart of a number of novel research directions, both as carriers of information and for the investigation of optical activity and chiral molecules. Optical vortex beams are beams of light with a helical wavefront and associated orbital angular momentum. They are typically generated using bulk optics methods or by a passive element such as a forked grating or a metasurface to imprint the required phase distribution onto an incident beam. Since many applications benefit from further miniaturization, a more integrated yet scalable method is highly desirable. Here, we demonstrate the generation of an azimuthally polarized vortex beam directly by an organic semiconductor laser that meets these requirements. The organic vortex laser uses a spiral grating as a feedback element that gives control over phase, handedness, and degree of helicity of the emitted beam. We demonstrate vortex beams up to an azimuthal index l = 3 that can be readily multiplexed into an array configuration.
