    The consumptive use of upland rice (Oryza sativa Linn.) grown during the wet season (kharif) as estimated by modified Penman, radiation, pan-evaporation and Hargreaves methods showed a variation from computed consumptive use estimated by the gravimetric method. The variability increased with an increase in the irrigation interval, and decreased with an increase in the level of N applied. The average variability was less in pan-evaporation method, which could reliably be used for estimating water requirement of upland rice if percolation losses are considered

    In this discussion of Hungary, attention is directed to the following: geography, people, history, government, political conditions, the economy, foreign relations, defense, and relations between the US and Hungary. In 1985 the population totaled 10.7 million with an annual growth rate of 0.2%. The infant mortality rate is 20.2/1000 live births; life expectancy is 66 years for men and 73.2 years for women. Hungary was a monarchy for almost 1000 years. Its constitutional parliamentary system preceded, by several centuries, the establishment of such Western-style governments in other East European countries. A communist dictatorship seized power in May/June 1947. The Hungarian uprising of 1956, although forcibly suppressed by Soviet armed intervention, gave impetus to long overdue changes and clearly demonstrated the popular will for national identity and internal reform. With the exception of various small businesses with few employees, all economic activity is run by state-owned enterprises or cooperatives. Agriculture has been collectivized. Hungary has rich bauxite mines and provides for most of its coal and natural gas requirements. Introduction of the "new economic mechanism" in 1968 ushered in a period of rapid growth, accompanied by equilibrium in the balance of trade. Yet, in the early 1970s a number of factors combined to blunt the reform effort, and in 1977 government leaders recognized the need for a new reform effort. Hungary is highly dependent on foreign trade, about 50% of which is with other communist countries. Except for the brief and unsuccessful attempt in November 1956 to establish a position and course of neutrality for Hungary, the foreign policy of the Hungarian government has followed closely the Soviet Union since 1947. In recent years, US/Hungarian relations have featured a steady exchange of official visits.

    The economy of Hungary remains intensive in both materials and energy. However, Hungary has the prospect of reducing energy intensity, as well as carbon emissions, by integrating itself with the world economy and introducing modern products and production technologies. This high energy intensity is relatively good news because it means that by changing the production structure, personal income may be increased considerably without necessarily increasing energy use and carbon emissions. The government significantly altered the Hungarian energy economy in 1978 by restricting oil and oil products use and requiring substitution with domestic coal, imported electricity, and natural gas. This decision required investment in energy supply to grow to 40% of all industrial investment by 1986

    Surface movement processes are constantly posing threat to property in populated and agricultural areas in the Gerecse hills (Hungary). The affected geological formations are mainly unconsolidated sediments. Pleistocene loess and alluvial terrace sediments are overwhelmingly present, but fluvio-lacustrine sediments of the latest Miocene, and consolidated Eocene and Mesozoic limestones and marls can also be found in the area. Landslides and other surface movement processes are being studied for a long time in the area, but a comprehensive GIS-based geostatistical analysis have not yet been made for the whole area. This was the reason for choosing the Gerecse as the focus area of the study. However, the base data of our study are freely accessible from online servers, so the used method can be applied to other regions in Hungary. Qualitative data was acquired from the landslide-inventory map of the Hungarian Surface Movement Survey and from the Geological Map of Hungary (1 : 100 000). Morphometric parameters derived from the SRMT-1 DEM were used as quantitative variables. Using these parameters the distribution of elevation, slope gradient, aspect and categorized geological features were computed, both for areas affected and not affected by slope movements. Then likelihood values were computed for each parameters by comparing their distribution in the two areas. With combining the likelihood values of the four parameters relative hazard values were computed for each cell. This method is known as the "empirical probability estimation" originally published by Chung (2005). The map created this way shows each cell's place in their ranking based on the relative hazard values as a percentage for the whole study area (787 km2). These values provide information about how similar is a certain area to the areas already affected by landslides based on the four predictor variables. This map can also serve as a base for more complex landslide vulnerability studies involving

    Full Text Available The number of Adonis vernalis populations, their size and abundance in xerothermic communities of the Lublin Upland have decreased significantly in the last 40-50 years, which indicates that there is a real risk of species extinction in the studied area. The paper is an attempt to indicate the possible factors which influence the decrease of Adonis vernalis populations. Detailed studies were carried out in six sites differing habitat conditions, land use and the size of Adonis vernalis populations. Observations were made of the abundance of blooming and the number of anthers per flower. The ability for reproduction was estimated indirectly by the mass of pollen delivered and its biological value. The populations of Adonis vernalis differ in number of anthers per flower (94.4 - 131.5, on average, the mass of pollen delivered (0.83 mg - 3.18 mg per 100 anthers, on average, the biological value of pollen and the size of pollen grains. Generally, stronger populations were characterized by better quality and a higher quantity of pollen. Potential energy of pollen in flowers from Pliszczyn and Łabunie was 69-72%, compared to 36%-47% in the remaining populations. Grass burning did not cause a reduction of potential biological value of Adonis vernalis pollen. Xerothermic swards in Pliszczyn and Kąty regularly burnt developed strong, most abundant populations of Adonis vernalis with favorable pollen. The development of the shrub layer, if it is out of control, stands in the way of satisfactory reproduction of halophilous Adonis vernalis.

    To investigate the greenhouse gases emissions from paddy fields and uplands, methane and nitrous oxide emissions were estimated from local measurement and the IPCC guidelines during 1990-2000 in Taiwan. Annual methane emission from 182 807 to 242 298 ha of paddy field in the first crop season ranged from 8062 to 12 066 ton, and it was between 16 261 and 25 007 ton for 144 178-211 968 ha in the second crop season with local measurement. The value ranged from 12 132 to 17 465 ton, and from 16 046 to 24 762 ton of methane in the first and second crop season with the IPCC guidelines for multiple aeration treatments, respectively. Annual nitrous oxide emission was between 472 and 670 ton and between 236 and 359 ton in the first and second crop season, respectively. Methane and nitrous oxide emissions from uplands depend on crop, growth season, fertilizer application and environmental conditions. Annual methane emission from upland crops, vegetable, fruit, ornamental plants, forage crops and green manure crops was 138-252, 412-460, 97-100, 3-5, 4-5 and 3-51 ton, respectively. Annual nitrous oxide emission was 1080-1976, 1784-1994, 2540-2622, 31-54, 43-53 and 38-582 ton, respectively. Annual nitrous oxide emission ranged from 91 to 132 ton for 77 593-112 095 ton of nitrogen-fixing crops, from 991 to 1859 ton for 325 9731-6 183 441 ton of non-nitrogen-fixing crops, and from 1.77 to 2.22 Gg for 921 169-1 172 594 ton of chemical fertilizer application. In addition, rice hull burning emitted 19.3-24.2 ton of methane and 17.2-21.5 ton of nitrous oxide, and corn stalk burning emitted 2.1-4.2 ton of methane and 1.9-3.8 ton of nitrous oxide. Methane emission from the agriculture sector was 26 421-37 914 ton, and nitrous oxide emission was 9810-11 649 ton during 1990-2000 in Taiwan. Intermittent irrigation in paddy fields reduces significantly methane emission; appropriate application of nitrogen fertilization and irrigation in uplands and paddy fields also decreases nitrous oxide

    Plant breeders are more interested in genetic variance rather than phenotypic variance because it is amenable to selection and bring further improvement in the character. Twenty-eight F/sub 2/ progenies were tested in two environments so as to predict genetic variances, heritability estimates and genetic gains. Mean squares for locations were significant for all the five traits suggesting that genotypes performed differently under varying environments. Genetic variances, in most cases, however, were about equal to that of phenotypic variances consequently giving high heritability estimates and significant genetic gains. The broad sense heritability estimates were; 94.2, 92.9, 33.6, 81.9 and 86.9% and genetic gains were; 30.19, 10.55,0.20,0.89 and 1.76 in seed cotton yield, bolls per plant, lint %, fibre length and fibre uniformity ratio, respectively. Substantial genetic variances and high heritability estimates implied that these characters could be improved through selection from segregating populations. (author)

    The experimental research was conducted so as to determine the general combining ability (GCA) and specific combining ability (SCA) estimates and heterotic effects for seed cotton yield and fibre traits in 5 x 5 half diallel crosses of upland cotton (Gossypium hirsutum L.). The parental genotypes studied were; CRIS-134, IR-3701, IR-1524, FH-113 and MG-6. The characters such as bolls/plant, sympodial branches/plant, boll weight (g), plant height (cm), fibre length (mm), seed cotton yield/plant (g), seed index (g) and ginning out turn percentage were studied. The experiment was laid-out in a randomized complete block design with four replications at experimental field of the Department of Plant Breeding and Genetics, Sindh Agriculture University Tandojam, Pakistan during 2013. The results revealed that, parents and hybrids differed significantly for their mean performance regarding all the traits studied. The importance of heterotic effects was evident from the significance of parents vs. hybrids performance. The variances due to GCA and SCA were significant for all the traits except that GCA was non-significant for boll weight only whereas, SCA was non-significant for boll weight, seed index and ginning out turn percentage. The significance of GCA indicated the importance of additive genes advocating the traits while, the involvement of non-additive genes was evident from the significance of SCA variances. The GCA variances were greater than SCA for bolls per plant, plant height, seed cotton yield and lint percentage while, SCA variances were higher than GCA for sympodial branches/plant and fibre length. Parents IR-3701, FH-113 and MG-6 displayed higher positive GCA effects for bolls/plant, sympodial branches/plant, fibre length, seed cotton yield, seed index and ginning out turn percentage. The per se performance of these three parents was exactly reflected in their GCA effects and such happenings are exceptional. Such results suggested that, all three parents were

    Purpose: The typically benign, but occasionally rapidly fatal clinical course of papillary thyroid cancer has raised the need for individual survival probability estimation, to tailor the treatment strategy exclusively to a given patient. Materials and methods: A retrospective study was performed on 400 papillary thyroid cancer patients with a median follow-up time of 7.1 years to establish a clinical database for uni- and multivariate analysis of the prognostic factors related to survival (Kaplan-Meier product limit method and Cox regression). For a more precise prognosis estimation, the effect of the most important clinical events were then investigated on the basis of a Markov renewal model. The basic concept of this approach is that each patient has an individual disease course which (besides the initial clinical categories) is affected by special events, e.g. internal covariates (local/regional/distant relapses). On the supposition that these events and the cause-specific death are influenced by the same biological processes, the parameters of transient survival probability characterizing the speed of the course of the disease for each clinical event and their sequence were determined. The individual survival curves for each patient were calculated by using these parameters and the independent significant clinical variables selected from multivariate studies, summation of which resulted in a mean cause-specific survival function valid for the entire group. On the basis of this Markov model, prediction of the cause-specific survival probability is possible for extrastudy cases, if it is supposed that the clinical events occur within new patients in the same manner and with the similar probability as within the study population. Results: The patient's age, a distant metastasis at presentation, the extent of the surgical intervention, the primary tumor size and extent (pT), the external irradiation dosage and the degree of TSH suppression proved to be

    Water levels beneath parts of Averill Park, a residential hamlet in an upland area of till-mantled shale bedrock in east-central New York, have declined in response to increased withdrawals from new wells. Similar experiences in many upland localities in the northeastern United States have resulted in awareness that the rate of recharge to bedrock can be an important constraint on the density of new development in uplands. Recharge at Averill Park was calculated on the basis of careful estimation of pumpage within a defined cone of depression. The data-collection and recharge-estimation procedures documented herein could be applied in a variety of upland localities in support of community-planning studies. Static water levels measured in 145 wells at Averill Park during the late summer of 2002 defined a 0.54-square-mile cone of depression within which ground-water discharge took place entirely as withdrawals from wells. Rates of withdrawal were estimated largely from surveys in similar neighborhoods a few miles away served by public water supply. Comparison of the water-level measurements in 2002 with measurements on other dates revealed localized declines that could be attributed to new housing developments or commercial demands, but also demonstrated that water levels in 2002 within the cone of depression had stabilized and were not declining persistently over time. Therefore, the current withdrawals were equated to recharge from infiltrating precipitation. Recharge within this area was estimated to average 104 gallons per day per acre, equivalent to 1.4 inches annually, and was sufficient to sustain a residential population of 1.9 persons per acre. This recharge rate is much lower than rates estimated from streamflow records for upland watersheds elsewhere in the northeastern United States. This rate is an average of an unknown larger rate in the 30 percent of the study area where bedrock is discontinuously overlain by less than 30 feet of till and an unknown

    The paper summarises the results to determine the fluxes of different N-compounds within the atmosphere and an aquatic and a terrestrial ecosystems, in Hungary. In the exchange processes of N-compounds between atmosphere and various ecosystems the deposition dominates. The net deposition fluxes are -730, -1 270 and -1530 mg N m -2 yr -1 for water, grassland, and forest ecosystems, respectively. For water, the main source of nitrogen compounds is the wet deposition. Ammonia gas is close to the equilibrium between the water and the air. For grassland the dry flux of nitric acid and ammonia is also an important term beside the wet deposition. Dry deposition to terrestrial ecosystems is roughly two times higher than wet deposition. A total of 8-10% of the nitrates and NH x deposited to terrestrial ecosystems are re-emitted into the air in the form of nitrous oxide (N 2 O) greenhouse gas. - The paper summarises the results of works to determine the N-flux between atmosphere and terrestrial/aquatic ecosystems in Hungary

    Full text: This work has been performed as part of the EC project SAVEC (Spatial Analysis of Vulnerable Areas in Central Europe) under DGXII, expanding the EC project SAVE (Spatial Analysis of Vulnerable Ecosystems in Europe) under DGXI. The scope of this work was to collect data on 137 Cs contamination of foodstuffs after the Chernobyl accident and dietary habits varying according to district, age, gender and profession across the three Central-European countries. The spatial variation in 137 Cs intake from contaminated foodstuffs could thus be estimated. Dietary data from Poland, based on household budget surveys, are broken down according to region, country, age, gender and socio-economic status. Data from Hungary, based on household budget surveys, are broken down according to region, age and gender. Data from the Czech Republic, based on national consumption statistics, are only available at a national scale and according to age. The regional variation in estimated 137 Cs intake after a fallout event is presented in GIS maps, pointing out the regions most at risk due to dietary habits in Poland and Hungary. For Poland, the groups most at risk according to socio-economic status are also presented. Whole body measurements of 137 Cs were performed by whole body counting and 24-hour urine samples. Intakes calculated from whole body measurements are compared to intakes estimated from consumption/contamination data. The two methods show some discrepancies. Reasons for this are discussed and include: dietary data collection, consumption development, wild foodstuffs consumption and gaps in post-Chernobyl food contamination data. (author)

    This exploratory research on Cryptic Methane Emissions from Upland Forest Ecosystems was motivated by evidence that upland ecosystems emit 36% as much methane to the atmosphere as global wetlands, yet we knew almost nothing about this source. The long-term objective was to refine Earth system models by quantifying methane emissions from upland forests, and elucidate the biogeochemical processes that govern upland methane emissions. The immediate objectives of the grant were to: (i) test the emerging paradigm that upland trees unexpectedly transpire methane, (ii) test the basic biogeochemical assumptions of an existing global model of upland methane emissions, and (iii) develop the suite of biogeochemical approaches that will be needed to advance research on upland methane emissions. We instrumented a temperate forest system in order to explore the processes that govern upland methane emissions. We demonstrated that methane is emitted from the stems of dominant tree species in temperate upland forests. Tree emissions occurred throughout the growing season, while soils adjacent to the trees consumed methane simultaneously, challenging the concept that forests are uniform sinks of methane. High frequency measurements revealed diurnal cycling in the rate of methane emissions, pointing to soils as the methane source and transpiration as the most likely pathway for methane transport. We propose the forests are smaller methane sinks than previously estimated due to stem emissions. Stem emissions may be particularly important in upland tropical forests characterized by high rainfall and transpiration, resolving differences between models and measurements. The methods we used can be effectively implemented in order to determine if the phenomenon is widespread.

    Nowadays, as the practice of extreme sports is spreading, potholing is becoming more and more popular. As a result, both the number of cavers and the time spent in the caves have been on the rise. There are some cavers known to have spent some 5000 h in caves over a span of 10 years. In poorly ventilated caves, radon exhalated from cave rocks and deposits may accumulate and cause significant doses to cavers. In this study, the radon concentration in seven caves in the Bakony Mountains, Hungary, was measured by continuous and integrated measurement devices. Measured values for the different caves were rather different, and varied between 50 and 24,000 Bq m -3 . The average radon concentration over the measurement period was approximately 10,000 Bq m -3 in five of the seven caves inspected. By assuming an average of 470 h year -1 spent in caves, effective doses to cavers were estimated. The expected annual effective dose, in case of an equilibrium factor of 0.6, was 19.7 mSv.

    It is known that tobacco leaves may contain 210 Pb and 210 Po in significant concentrations. The cumulative alpha-radiation dose due to the radioactive content of inhaled cigarette smoke and the increasing number of lung cancer cases explain the importance of the investigation. The present study investigated the activity concentrations of these two radionuclides in 29 Hungarian cigarette samples. The relation between 210 Po/ 210 Pb activity and nicotine/tar content of these cigarettes was also examined. 210 Po was determined by alpha spectrometry using a PIPS detector after chemical leaching and spontaneous deposition of 210 Po on a high nickel-content (25%) stainless steel disk. The 210 Pb activity was calculated from the 210 Po originated from the decay of 210 Pb after a waiting period of eight months. The 210 Po activity concentrations of the measured types of cigarettes ranged from 10.0 to 33.5 mBq/cigarette, and the activity of 210 Pb varied from 9.6 to 32.5 mBq/cigarette. The average annual committed effective dose is estimated to be 185.6±70.6μSv/y and 58.7±22.7μSv/y due to cigarette smoking (20 cigarettes/day) for 210 Po and 210 Pb, respectively

    Country Profile: Hungary has been prepared as a background document for use by US Government agencies and US businesses interested in becoming involved with the new democracies of Eastern Europe as they pursue sustainable economic development. The focus of the Profile is on energy and highlights information on Hungary`s energy supply, demand, and utilization. It identifies patterns of energy usage in the important economic sectors, especially industry, and provides a preliminary assessment for opportunities to improve efficiencies in energy production, distribution and use by introducing more efficient technologies. The use of more efficient technologies would have the added benefit of reducing the environmental impact which, although is not the focus of the report, is an issue that effects energy choices. The Profile also presents considerable economic information, primarily in the context of how economic restructuring may affect energy supply, demand, and the introduction of more efficient technologies.

    Hungary recognises the importance of limiting greenhouse gas emissions in order to prevent or mitigate their impact on the global climate. On an international level, Hungary is not a significant carbon dioxide emitter, neither to the absolute degree nor on a per capita basis. This means that the principal reason for Hungarian participation in emission`s reduction is not perceivable international consequences but solidarity and participation in the common action of the countries of the world. Hungary is a signatory to both the Framework Convention on Climate Change and the Kyoto protocol. However, the (Hungarian) National Environmental Program also emphasises that the fulfilment of international conventions must happen at a level and pace reasonable for Hungary. The goal of this study is to investigate the potentials, costs and implementation strategies of greenhouse gas abatement in Hungary. First presented is a background of Hungary`s economy and a summary of the economic transitions in Hungary. A brief description of the Hungarian energy sector is included, with a short summary of carbon dioxide emissions, and of the Hungarian forestry sector. The following chapter is devoted to the development of baseline scenarios, from bottom-up and top-down perspectives. In the chapter on mitigation, the spectrum of energy efficiency measures in the residential and public sectors is discussed. Fifteen specific measures, whose impact is considered important, are selected and discussed in detail. The cost curves are developed for the discussed mitigation options. Then, we discuss the issues related to the implementation of energy efficiency measures in the Hungarian residential and commercial sectors. After a general background and a framework on the implementation of the energy efficiency measures in the sectors chosen, we elaborate on the practicality of these concepts. As a case study, the concept and the feasibility of carbon/energy taxes are examined. To complete the

    A field unit was installed in the city of Debrecen (East Hungary) during the summer of 2008 to monitor urban atmospheric fossil fuel CO 2 . To establish a reference level simultaneous CO 2 sampling has been carried out at a rural site (Hegyhatsal) in Western Hungary. Using the Hungarian background 14 CO 2 observations from the rural site atmospheric fossil fuel CO 2 component for the city of Debrecen was reported in a regional 'Hungarian' scale. A well visible fossil fuel CO 2 peak (10-15 ppm) with a maximum in the middle of winter 2008 (January) was observed in Debrecen air. Significant local maximum (∼20 ppm) in fossil fuel CO 2 during Octobers of 2008 and 2009 was also detected. Stable isotope results are in agreement with the 14 C based fossil fuel CO 2 observations as the winter of 2008 and 2009 was different in atmospheric δ 13 C variations too. The more negative δ 13 C of atmospheric CO 2 in the winter of 2008 means more fossil carbon in the atmosphere than during the winter of 2009. (author)

It identifies patterns of energy usage in the important economic sectors, especially industry, and provides a preliminary assessment for opportunities to improve efficiencies in energy production, distribution and use by introducing more efficient technologies. The use of more efficient technologies would have the added benefit of reducing the environmental impact which, although is not the focus of the report, is an issue that effects energy choices. The Profile also presents considerable economic information, primarily in the context of how economic restructuring may affect energy supply, demand, and the introduction of more efficient technologies.

  6. Acidification policy in Hungary

    1992-01-01

    Hungary's policy for air pollution abatement aims to reduce air pollution in cities and industrialised areas, to maintain air quality in relatively 'clean' regions, and to fulfill its obligations to the UN-ECE Convention and Protocols on long-range transboundary air pollution. Emissions of NO x and SO x in Hungary have decreased considerably in the last decade although nitrogen oxide emission from cars has remained unchanged. A catalyst programme is planned to reduce NO x , hydrocarbons and CO emissions. Results of some air pollution monitoring programmes are quoted. Acidification of soils has increased over the last decade. Legislation on air pollution due to be issued in 1992 covers sulphur content of fuels, emission limits, establishing critical loads, and setting up a comprehensive monitoring system. 5 refs., 3 tabs

  7. Hungary and the Balkans

    Full Text Available As regards the Balkans, Hungary is one of the intermediary regions in Europe. At the same time, the Balkans is the tie-up territory between Turkey, one of the emerging regions today, and Hungary, which aims to cooperate with it. Being a NATO and EU member state it takes part in the geopolitical games that are played between the EU, Russia, the USA and some of the countries of the Islamic world. These dealings fundamentally determine tasks in Hungarian foreign policy, cultural policy, economic policy, security- and defence policy for the forthcoming decades. Hungary acts as a gate between Western Europe and the Balkans. This role used to be more dominant in previous centuries of Hungarian history than it is today, not least because the country's size and strength significantly decreased after the Trianon Treaty. Many of the historical, imperial reflexes have remained, but without any imperial gravity. Today we are just one of the intermediary regions that have relations with the Balkans and form a bridge to Europe. The accelerated alteration in the world order, the BRICS countries and the emergence of some important middle-sized states, such as Turkey, make adaptation inevitable for our country. This is what the policy of 'Eastern opening' is about.

  8. Estimation of best parents parents and superior cross combinations for yield and fiber quality related traits in upland cotton (gossypium hirsutum L.)

    Combining ability was studied for identification of potential cultivars and hybrids in upland cotton (Gossypium hirsutum L.) in a 6x6 set of diallel crosses among six genotypes of cotton, i.e., VH-232, CRS-2007, SB-149, GR-156, FH-207, and MARVI carried out on fiber length, fiber fineness, fiber elongation, fiber strength, ginning out tern (GOT) and seed cotton yield. Analysis of variance revealed highly significant (p < 0.01) differences among the genotypes for all traits. Combining ability studies showed that the mean squares, due to general combining ability (GCA), specific combining ability (SCA) and reciprocal effects were highly significant in F1 generation. Genetic components, due to GCA and SCA, revealed that traits, such as, fiber length, strength and fineness, showed high proportion of additive type of gene action in F1 generation because of greater GCA variances were greater than SCA variance. GR-156 was the best combiner for lint percentage and fiber length. FH-207 was the best combiner for fiber fineness. FH-207, MARVI and SB-149 were the best general combiners for fiber character and were suggested to be used in future breeding programme to improve fiber quality traits. CRS-2007 x GR-156, CRS-2007 x MARVI, SB-149 x MARVI and VH-232 x SB-149 had higher specific combining ability and reciprocal effects and they can be used for future breeding programme to improve fiber quality.

  9. Fusion research in Hungary

    2004-01-01

    Hungarian fusion research started in the 1970s, when the idea of installing a small tokamak experiment emerged. In return to computer equipment a soviet tokamak was indeed sent to Hungary and started to operate as MT-1 at the Central Research Institute for Physics (KFKI) in 1979. Major research topics included diagnostic development, edge plasma studies and investigation of disruptions. Following a major upgrade in 1992 (new vacuum vessel, active position control and PC network based data acquisition system) the MT-1M tokamak was used for the study of transport processes with trace impurity injection, micropellet ablation studies, X-ray tomography and laser blow-off diagnostic development. Although funding ceased in the middle of the 90's the group was held alive by collaborations with EU fusion labs: FZ -Juelich, IPP-Garching and CRPP-EPFL Lausanne. In 1998 the machine was dismantled due to reorganization of the Hungarian Academy of Sciences. New horizons opened to fusion research from 1999, when Hungary joined EURATOM and a fusion Association was formed. Since then fusion physics studies are done in collaboration with major EU fusion laboratories, Hungarian researchers also play an active role in JET diagnostics upgrade and ITER design. Major topics are pellet ablation studies, plasma turbulence diagnosis using Beam Emission Spectroscopy and other techniques, tomography and plasma diagnostics using various neutral beams. In fusion relevant technology R and D Hungary has less records. Before joining EURATOM some materials irradiation studies were done at the Budapest Research Reactor at KFKI-AEKI. The present day fusion technology programme focuses still on irradiation studies, nuclear material database and electromagnetic testing techniques. Increasing the fusion technology research activities is a difficult task, as the competition in Hungarian industry is very strong and the interest of organizations in long-term investments into R and D is rather weak and

  11. How old is upland catchment water?

    Hofmann, Harald; Cartwright, Ian; Morgenstern, Uwe; Gilfedder, Benjamin

    2014-05-01

    Understanding the dynamics of water supply catchments is an essential part of water management. Upland catchments provide a continuous, reliable source of high quality water not only for some of the world's biggest cities, but also for agriculture and industry. Headwater streams control river flow in lowland agricultural basins as the majority of river discharge emerges from upland catchments. Many rivers are perennial and flow throughout the year, even during droughts. However, it is still unclear how reliable and continuous upland catchment water resources really are. Despite many efforts in upland catchment research, there is still little known about where the water is stored and how long it takes to travel through upper catchments. Resolving these questions is crucial to ensure that this resource is protected from changing land use and to estimate potential impacts from a changing climate. Previous research in this important area has been limited by existing measurement techniques. Knowledge to date has relied heavily on the use of variation in stable isotope signals to estimate the age and origin of water from upland catchments. The problem with relying on these measures is that as the water residence time increases, the variation in the stable isotope signal decreases. After a maximum period of four years, no variation can be detected This means that to date, the residence time in upland catchments is likely to have been vastly underestimated. Consequently, the proportion of water flow out of upland river catchments to the total river flow is also underestimated. Tritium (3H) combines directly with water molecules and enters the flow paths with the infiltrating water. Its half-life (12.32 years) makes it ideal to describe residence times in upper catchment reservoirs as it can theoretically measure water up to about 150 years old. The bomb pulse peak in the southern hemisphere was several orders of magnitude lower than in the northern hemisphere. Hence the

    In Hungary wells producing geothermal water have been in operation since 1890. The economic exploitation of geothermal energy is possible in over 40% of the country due to favorable conditions such as large reserves, high ground pressure and high geothermal gradient. Some 620 wells presently working produce a considerable quantity of energy and thermal water, in most cases using the single well system but more recent operations now incorporate reinjection wells. Hydrotherapy water supply and various industrial uses, such as drying in the agricultural sector, are its most important uses but further uses of thermal energy are being developed especially that of heating buildings where it could replace other energy sources. Sufficient investment could see an expanding tourist industry based on the recognized therapeutic properties of these mineral waters.

  13. 2015 Easter bolide over North Hungary

    2015-01-01

    On Easter Monday, April 6, 2015, at UTC 17h31m (near sunset) there was a bright (peak magnitude -12 ~ -14) bolide which also produced a sonic boom, over North Hungary, close to Miskolc, above the Bükk mountains. The event was witnessed by many people, and recorded by several car dashboard-, meteorological and all sky cameras from as far away as Farád (North-West Hungary) and Görbeháza (North-East Hungary). Unfortunately, with the event having occurred only a few minutes after sunset, the sky was still bright and therefore the Hungarian Video meteor network cameras were not yet operating. Our team has collected and re-calibrated as much video and photo material as possible. Since there were very few direct images of the bolide itself, but more photos and videos of the persistent train left behind, these latter images were also used, in certain circumstances, in our calculations. The deduced final atmospheric path and heliocentric orbit are presented, along with the estimation of the errors.

    The aim of this study was to estimate the prevalence and causes of blindness, severe visual impairment (SVI), moderate visual impairment (MVI), and early visual impairment (EVI) and its causes in an established market economy of Europe. A cross-sectional population-based survey. A sample size of 3675 was calculated using the standard Rapid Assessment of Avoidable Blindness (RAAB) software in Hungary. A total of 105 clusters of 35 people aged 50 years or older were randomly selected with probability proportionate to size by the Hungarian Central Statistical Office. Households within the clusters were selected using compact segment sampling. Visual acuity (VA) was assessed with a Snellen tumbling E-chart with or without a pinhole in the households. The adjusted prevalences of bilateral blindness, SVI, MVI and EVI were 0.9% (95% CI: 0.6-1.2), 0.5% (95% CI: 0.2-0.7), 5.1% (95% CI: 4.3-5.9) and 6.9% (95% CI: 5.9-7.9), respectively. The major causes of blindness in Hungary were age-related macular degeneration (AMD; 27.3%) and other posterior segment diseases (27.3%), cataract (21.2%) and glaucoma (12.1%). Cataract was the main cause of SVI, MVI and EVI. Cataract surgical coverage (CSC) was 90.7%. Of all bilateral blindness in Hungary, 45.5% was considered avoidable. This study proved that RAAB methodology can be successfully conducted in industrialized countries, which often lack reliable epidemiologic data. The prevalence of blindness was relatively low, with AMD and other posterior segment diseases being the leading causes, and cataract is still a significant cause of visual impairment. © 2017 Acta Ophthalmologica Scandinavica Foundation.

    It is known that tobacco leaves may contain {sup 210}Pb and {sup 210}Po in significant concentrations. The cumulative alpha-radiation dose due to the radioactive content of inhaled cigarette smoke and the increasing number of lung cancer cases explain the importance of the investigation. The present study investigated the activity concentrations of these two radionuclides in 29 Hungarian cigarette samples. The relation between {sup 210}Po/{sup 210}Pb activity and nicotine/tar content of these cigarettes was also examined. {sup 210}Po was determined by alpha spectrometry using a PIPS detector after chemical leaching and spontaneous deposition of {sup 210}Po on a high nickel-content (25%) stainless steel disk. The {sup 210}Pb activity was calculated from the {sup 210}Po originated from the decay of {sup 210}Pb after a waiting period of eight months. The {sup 210}Po activity concentrations of the measured types of cigarettes ranged from 10.0 to 33.5 mBq/cigarette, and the activity of {sup 210}Pb varied from 9.6 to 32.5 mBq/cigarette. The average annual committed effective dose is estimated to be 185.6{+-}70.6{mu}Sv/y and 58.7{+-}22.7{mu}Sv/y due to cigarette smoking (20 cigarettes/day) for {sup 210}Po and {sup 210}Pb, respectively.

  2. Reforming health care in Hungary.

    Science.gov (United States)

    Császi, L; Kullberg, P

    1985-01-01

    Over the past two decades Hungary has initiated a series of social and economic reforms which have emphasized decentralization of control and the reintroduction of market mechanisms into the socialized economy. These reforms both reflect and reinforce a changing social structure, in particular the growing influence of upper class special interest groups. Market reforms are an expression of concurrent ideological shifts in Hungarian society. We examined the political significance of three recent proposals to reform health services against the backdrop of broader social and economic changes taking place. The first proposes a bureaucratic reorganization, the second, patient co-payments, and the third, a voucher system. The problems each proposal identifies, as well as the constituency each represents, reveal a trend toward consolidation of class structure in Hungary. Only one of these proposals has any potential to democratize the control and management of the heath care system. Moreover, despite a governmental push toward decentralization, two of these proposals would actually increase centralized bureaucratic control. Two of the reforms incorporate market logic into their arguments, an indication that the philosophical premises of capitalism are re-emerging as an important component of the Hungarian world-view. In Hungary, as well as in other countries, social analysis of proposed health care reforms can effectively illuminate the social and political dynamics of the larger society.

    In this study, several Hungarian dwellings and working places were surveyed using passive radon- and thoron-measuring devices (Radopot R and Raduet R from 2003 to 2008. The detectors were placed 15-30 cm from the wall throughout the 1-to 3-month period. In dwellings, the presence of thoron, ∼100 Bq m -3 , was detected almost in all cases; however, in the cellars of these buildings, a value ∼200 Bq m -3 was typical. In the cases of manganese and bauxite mines, the concentration of thoron was mainly 200 and 500 Bq m -3 , respectively. In caves, it was 1000 Bq m -3 , whereas in the radon bath it was ∼100 Bq m -3 . As in many cases, the ratio between thoron and radon concentrations was > 0.25 and the dose contribution from thoron and its progeny was not negligible. Therefore, further investigation on the thoron progeny will be necessary for an accurate dose estimation. (authors)

    Reproductive human cloning is prohibited in Hungary, as in many other countries. Therapeutic human cloning is not prohibited, just like in many other countries. Stem cell therapy is also allowed. Article III, paragraph (3) of the Hungarian basic law (constitution) strictly forbids total human cloning. Article 1 of the Additional Protocol to the Oviedo Convention, on the Prohibition of Cloning Human Beings (1998) stipulates that any intervention seeking to create a human being genetically identical to another human being, whether living or dead, is prohibited. In Hungary, according to Article 174 of the Criminal Code, total human cloning constitutes a crime. Article 180, paragraph (3) of the Hungarian Act on Health declares that embryos shall not be brought about for research purposes; research shall be conducted only on embryos brought about for reproductive purposes when this is authorized by the persons entitled to decide upon its disposal, or when the embryo is damaged. Article 180, paragraph (5) of the Hungarian Act on Health stipulates that multiple individuals who genetically conform to one another shall not be brought about. According to Article 181, paragraph (1) of the Hungarian Act on Health, an embryo used for research shall be kept alive for not longer than 14 days, not counting the time it was frozen for storage and the time period of research.

  8. Hungary as an aging society.

    Blasszauer, B; Hazafi, K

    1994-12-01

    The authors describe the situation of the aged in Hungary, with a particular focus on the medical and ethical problems that health professionals have to face. The so-called post-communist transitional period is characterised by both economic and moral crisis. The country has a serious foreign debt problem as well as high rate of unemployment and crime, a considerable price inflation, and the pauperisation of the people, particularly among the old. The old are defined as those who have reached retirement age, which is 55 for women and 60 for men. Hungary lacks the kind of incentives that would provide good reasons to live much beyond the age of 60. There is neither a suitable culture for old age nor economic security, and this seriously undermines the independence and autonomy of the old. Neither family nor institutional care for the elderly is adequate. Although over 20 per cent of the population are retired, they are not organized as a political power that would effectively represent them. The health care system is in crises and the elderly suffer the most because of it. Therapeutic nihilism and both over-treatment and under-treatment of the aged is common. Among the old, the suicide rate is high. Because of a lack of funds, an inadequate number of experts, indifference to rehabilitation, and the infrequent use of technological interventions, home and institutional care are inadequate. There are no public debates on setting priorities or allocating limited resources. There are, however, high hopes for the success of a market economy, privatization, and well-functioning democracy.(ABSTRACT TRUNCATED AT 250 WORDS)

    1999-01-01

    pillow can be a problem. The energy budget melt formulation proves useful in understanding the energy components of melt typical of upland Britain. It reveals that, during the main melt phase, melt can occur in almost equal measure by sensible heat exchange and by latent heat of condensation, as warm air near saturation in cloud condenses on the snowpack; net radiation makes a negligible contribution. This provides a physical explanation for the success of the simple temperature excess approach to snowmelt estimation.

  12. Application of SPARROW modeling to understanding contaminant fate and transport from uplands to streams

    Ator, Scott; Garcia, Ana Maria.

    2016-01-01

    Understanding spatial variability in contaminant fate and transport is critical to efficient regional water-quality restoration. An approach to capitalize on previously calibrated spatially referenced regression (SPARROW) models to improve the understanding of contaminant fate and transport was developed and applied to the case of nitrogen in the 166,000 km2 Chesapeake Bay watershed. A continuous function of four hydrogeologic, soil, and other landscape properties significant (α = 0.10) to nitrogen transport from uplands to streams was evaluated and compared among each of the more than 80,000 individual catchments (mean area, 2.1 km2) in the watershed. Budgets (including inputs, losses or net change in storage in uplands and stream corridors, and delivery to tidal waters) were also estimated for nitrogen applied to these catchments from selected upland sources. Most (81%) of such inputs are removed, retained, or otherwise processed in uplands rather than transported to surface waters. Combining SPARROW results with previous budget estimates suggests 55% of this processing is attributable to denitrification, 23% to crop or timber harvest, and 6% to volatilization. Remaining upland inputs represent a net annual increase in landscape storage in soils or biomass exceeding 10 kg per hectare in some areas. Such insights are important for planning watershed restoration and for improving future watershed models.

  13. [Migration of dentists within Hungary].

    2010-09-01

    Concerning the human resource management in the health care, Hungarian analysts focus mainly on cross-national migration, which was instigated considerably by joining the European Union in 2004. Contrasted to other health care professionals, dentists emphasized also the importance of in-country migration (mobility) indicating serious dangers of developing inequalities in the dental service. From the point of view of health system planning, the main problem is to balance the needs and the number of professionals in regions and areas with extremely different socio-economic conditions. Under dictatorial governments, this "balancing" (which was experienced also in Hungary) is a forced allocation of young professionals to the target regions. In political freedom and free market economy, these measures are unthinkable. The present domestic area distribution, concerning also the supply through vacancies by old age inactivity and cross-national migration, is ruled by personal decisions of actually graduated and immigrant professionals respectively. Therefore, it is unavoidable to investigate the interrelation of factors (dentists' births place, study migration and decisions for practice allocation) ruling the in-country geographic patterns of dental practices. This evidence-based knowledge can only explain the present situation and provide guidelines for health policy decision makers.

    1980-09-01

    The democratic reform of public education in Hungary after the Second World War brought about a system which now includes Day-Care from the ages of 4-6 and compulsory Elementary School education up to the age of 16. A high proportion of students go on to Secondary education in vocational schools, special schools or grammar shools. The system is supplemented by career-counselling and provision for children with difficult home-backgrounds and for the mentally-retarded. District Councils are responsible for the schools in their areas and for the zoning that determines which schools children should attend. The environment of a school has a strong influence not only upon the standard of its facilities and the quality of its staff but also upon the function it is expected to fulfil in the community. Achievement is directly related to the degree of urbanization, but the increasing participation of farming-co-operatives in education in rural areas promises well for the development of better facilities and mutual understanding there. Housing estates in high-density residential areas make special demands which are being met in different ways. The role of the school in general is being expanded to include children's leisure time activities; at the same time factories are making a significant contribution locally through vocational guidance, financial help, and training-for-work programmes. Councils are implementing the requirements of public education resolutions to integrate school education into the whole scheme of public education, co-ordinating the activities of all social and cultural institutions, and developing new multi-functional complexes, to give a more effective and efficient service to the whole community.

    Bears (Ursus americanus) primarily occur in upland habitats in the Southeast because uplands were the last to be developed for agriculture and were more likely to become publicly owned. National parks and forests created in the early to mid-1900s served as sources to supply surrounding uplands with bears. Bears could not survive in southeastern...

  20. Climate and Energy Policy in Hungary

    Directory of Open Access Journals (Sweden)

    Maria Csete

    2012-02-01

    Full Text Available The energy problem has been redefined as one of the most important elements of sustainable development by climate change, adaptation and mitigation. Meeting energy needs is always a current issue in Hungary, irrespective of climate change because of the country’s high dependency on oil and gas imports, limited opportunities to replace them with domestic production, and the pollution associated with using fossil energy sources. Increasing effectiveness and saving energy can provide relatively short-term solutions with bearable costs and a relatively quick return on investment. The aim of the present paper is to give an overview about the climate and energy policy in Hungary with a special focus on the new energy strategy. Energy policy has a pivotal role in the economic recovery plan of the Hungarian government. The National Energy Strategy 2030 taking shape in Hungary takes climate policy into account with respect to adaptation and mitigation and lists renewable energy sources as the second most important tool for achieving strategic goals. As in most countries, it is also possible in Hungary to introduce climate strategy measures with zero social costs. The expedient management of climate change requires the combination of prevention, adaptation and dissemination initiatives. Strategies must meet a dual requirement: they must face the economic risks associated with premature measures, while also considering the adverse effects of delay.

    2016-11-01

    Full Text Available Wind erosion susceptibility of Hungarian soils was mapped on the national level integrating three factors of the complex phenomenon of deflation (physical soil features, wind characteristics, and land use and land cover. Results of wind tunnel experiments on erodibility of representative soil samples were used for the parametrization of a countrywide map of soil texture compiled for the upper 5 cm layer of soil, which resulted in a map representing threshold wind velocity exceedance. Average wind velocity was spatially estimated with 0.5′ resolution using the Meteorological Interpolation based on Surface Homogenised Data Basis (MISH method elaborated for the spatial interpolation of surface meteorological elements. The probability of threshold wind velocity exceedance was determined based on values predicted by the soil texture map at the grid locations. Ratio values were further interpolated to a finer 1 ha resolution using sand and silt content of the uppermost (0–5 cm layer of soil as spatial co-variables. Land cover was also taken into account, excluding areas that are not relevant to wind erosion (forests, water bodies, settlements, etc., to spatially assess the risk of wind erosion. According to the resulting map of wind erosion susceptibility, about 10 % of the total area of Hungary can be identified as susceptible to wind erosion. The map gives more detailed insight into the spatial distribution of wind-affected areas in Hungary compared to previous studies.

    1996-01-01

    The concentration and uptake of macro nutrients, micro nutrients and toxic elements were compared to dry matter yield, biomass components and primary and secondary tillering. Plant tissue analysis of N, P, K, Ca, Mg, Cl, Fe, Mn, Na, Ca, Al, Cr, As, Th and Ce were carried out using chemical and neutron activation analysis. N and K were found to accumulate in the green vegetative biomass whereas P, Ca, Mg, Fe and Zn were bound in the dead-plus-senesced component. Compared to control, urea fertilization increased the dry matter yield and uptakes of N, P, Ca, Mg, Fe, Mn, Na, Al, Th and Ce by upland rice. In addition to similar increases; cattle manuring also increased the green vegetative biomass, secondary tillering and uptake of K, Cl, Co, Cr and As. With the exception of Th uptake, upland rice Oryza Sativa var. Seri Pelanduk subjected to cattle manuring responded better to the uptake of various elements and produced more secondary tillers

  7. Performance Persistence of Equity Funds in Hungary

    2011-03-01

    Full Text Available This study examines the phenomenon of performance persistence of equity funds in Hungary in two time perspectives: 1-year and 6-month perspectives. The empirical results confirm the occurrence of performance dependence in consecutive periods. There is also a strong evidence of short-term persistence in the total horizon of the study (from the beginning of 2000 to the end of 2009, and in several sub-periods. The 1-year persistence was also found in the tested sample and, in general, depended on the measure applied. Furthermore, I observed performance reversal, which can be partly explained by trend changes in the financial markets. The persistence of equity funds performance in Hungary is shaped by market factors rather than the diversity of managerial characteristics.

    Medical care in Hungary has made significant progress since World War II in spite of other social priorities which have limited financial support of the health system. A shortage of hard currency in a high technological era is now having a particularly severe adverse impact on further development. Decentralized administration and local finance have, however, provided some room for progress. Preventive efforts are hampered by a deeply entrenched life style which is not conducive to improving the population's health status.

    Trends in divorce in Hungary in 1980 are examined using data from official sources. Having presented the data, the author attempts to identify the factors affecting the frequency of divorce, including educational status, geographic factors, income, and social class. In a concluding section devoted to the future of marriage, the author suggests that stable marriages based primarily on emotional rather than economic foundations will become less common, as the economic aspects of marriage are likely to increase rather than decrease in importance.

    High quality elective dental care for foreign patients was not exceptional in Hungary before the collapse of the old regime in 1989. Nevertheless, it became business as usual only in the new era thanks to the open state borders and the international competitive market environment. Unfortunately, no scientific study concerning this phenomenon has been conducted so far, however its professional and economic significance has been indicated by day-to-day experience. Additionally, the term "dental tourism" also used in international scientific papers became a commonplace in Hungary with unfavourable connotations. The present survey was the first to study this phenomenon by scientific standards in the most involved areas, namely in the capital city Budapest and in three counties in the Western Hungarian Region. Data collecting was performed by a self-reported questionnaire sent via conventional mail to all members of the Dental Section of the Hungarian Medical Chamber practicing in those indicated regions. Respond rates were 20.65% in Budapest and 25.34% in Western Hungary. The sample obtained this way, clearly indicated dimensions of cross-border patient migration and its economic significance as well. In Western Hungary 80.81% of foreign patients came from the neighbouring Austria and two out of ten practices realized 40 to 100% of their income out of this business. In Budapest foreign patients' nationality was more diversified. The largest group arrived from the United Kingdom (9.93%). Nevertheless the economic impact of dental tourism in Budapest is not relevant and outbalanced by a considerable domestic demand on the local private market.

  14. Radiocaesium variability in upland sheep flocks

    Beresford, N.A

    2002-07-01

    Following the 1986 Chernobyl accident large areas of uplands in the United Kingdom were contaminated by radiocaesium. Consequently, the level of radiocaesium in the tissues of some sheep exceeded 1000 Bq kg{sup -1} fresh weight This is the limit adopted within the UK above which meat cannot enter the food chain. In 1986, restrictions were placed on the movement and slaughter of sheep in areas of west Cumbria, north Wales and Scotland. Whilst the number of farms under restriction has reduced considerably, some still remain restricted in 2002. Although a number of workers had noted considerable variability between the radiocaesium activities of individuals within sheep flocks there had been no analyses of causal effects. The work described here, combined studies on three upland farms within west Cumbria with controlled feeding experiments, to systematically assess the parameters which may contribute to such variability. Results from all three farms demonstrate a temporally consistent ranking of the {sup 137}Cs activity concentration of individual sheep within the study flocks. As there was also a correlation between the {sup 137}Cs activity concentration of ewes and their pre-weaned lambs it is likely that the same ewes are producing lambs in excess of the intervention limit in subsequent years. It is difficult to generalise as to which factors will contribute to {sup 137}Cs variability within a given upland flock; factors contributing to variation were not consistent between the study farms. However, the location grazed and/or vegetation selected by animals was a causal factor to the observed variability at all three farms. The transfer of radiocaesium from the diet to muscle of sheep was found to be determined by live-weight change and dry matter intake. Subsequent studies have suggested that protein turnover may be a potential mechanism for the relationship between dry matter intake and radiocaesium transfer. This hypothesis is supported by current understanding

    Release of greenhouse gases from thawing permafrost is potentially the largest terrestrial feedback to climate change and one of the most likely to occur; however, estimates of its strength vary by a factor of thirty. Some of this uncertainty stems from abrupt thaw processes known as thermokarst (permafrost collapse due to ground ice melt), which alter controls on carbon and nitrogen cycling and expose organic matter from meters below the surface. Thermokarst may affect 20-50% of tundra uplands by the end of the century; however, little is known about the effect of different thermokarst morphologies on carbon and nitrogen release. We measured soil organic matter displacement, ecosystem respiration, and soil gas concentrations at 26 upland thermokarst features on the North Slope of Alaska. Features included the three most common upland thermokarst morphologies: active-layer detachment slides, thermo-erosion gullies, and retrogressive thaw slumps. We found that thermokarst morphology interacted with landscape parameters to determine both the initial displacement of organic matter and subsequent carbon and nitrogen cycling. The large proportion of ecosystem carbon exported off-site by slumps and slides resulted in decreased ecosystem respiration postfailure, while gullies removed a smaller portion of ecosystem carbon but strongly increased respiration and N2 O concentration. Elevated N2 O in gully soils persisted through most of the growing season, indicating sustained nitrification and denitrification in disturbed soils, representing a potential noncarbon permafrost climate feedback. While upland thermokarst formation did not substantially alter redox conditions within features, it redistributed organic matter into both oxic and anoxic environments. Across morphologies, residual organic matter cover, and predisturbance respiration explained 83% of the variation in respiration response. Consistent differences between upland thermokarst types may contribute to the

    With growing concerns on the effects of climate change and land use practices on our soil resources, soil erosion by water is becoming a significant issue internationally. Since the 1964 publication of the first soil erosion map of Hungary, there have been several attempts to provide a countrywide assessment of erosion susceptibility. However, there has been no up-to-date map produced in the last decade. In 2016, a new, 1:100 000 scale soil erosion map was published, based on available soil, elevation, land use and meteorological data for the extremely wet year of 2010. The map utilized combined outputs for two spatially explicit methods: the widely used empirical Universal Soil Loss Equation (USLE) and the process-based Pan-European Soil Erosion Risk Assessment (PESERA) models. The present study aims to provide a detailed analysis of the model results. In lieu of available national monitoring data, information from other sources were used. The Soil Degradation Subsystem (TDR) of the National Environmental Information System (OKIR) is a digital database based on a soil survey and farm dairy data collected from representative farms in Hungary. During the survey all kind of degradation forms - including soil erosion - were considered. Agricultural and demographic data was obtained from the Hungarian Central Statistical Office (KSH). Data from an interview-based survey was also used in an attempt to assess public awareness of soil erosion risks. Point-based evaluation of the model results was complemented with cross-regional assessment of soil erosion estimates. This, combined with available demographic information provides us with an opportunity to address soil erosion on a community level, with the identification of regions with the highest risk of being affected by soil erosion.

  20. The prospects for nuclear heating in Hungary

    Papp, I.; Lynch, G.F.

    1989-09-01

    In assessing alternative nuclear heat sources, a joint study was undertaken between Canada and Hungary to determine the feasibility of using the SLOWPOKE Energy System that has recently been developed. The SLOWPOKE Energy System is a benign nuclear heat source designed to supply 10 thermal megawatts in the form of hot water for local heating systems in buildings and institutions. It uses a combination of inherent safety features, including natural convection circulation and negative reactivity coefficients, and engineered features to ensure an extremely safe system. A SLOWPOKE demonstration heating reactor has been constructed in Canada. The unit started operation in July 1987 and is currently undergoing an extensive test program. Since the nuclear heat source is small, operates at atmospheric pressure, and produces hot water below 100 deg. C, the complex high-pressure, and high-temperature systems essential for electricity production are eliminated. As a result, the nuclear heat source can be located close to the load and will require a minimum of operator attention. In this way, a SLOWPOKE Energy System can be considered much like the oil- or natural gas fired furnace it is designed to replace. The extensive use of hot water district heating systems in Hungary offers the opportunity to exploit such simple nuclear systems as base load heat sources without an extensive retrofit of the existing systems. In addition, the studies have concluded that there are many economically attractive sites for 10 MW SLOWPOKE Energy Systems within the existing networks. The low capital investment requirements, coupled with a high degree of localization, even for the first unit, are seen as additional factors that facilitate the transfer of the technology to Hungary. Simple nuclear heat sources, such as the SLOWPOKE Energy System, when applied to the Hungarian district heating systems, offer the prospects of a significant reduction in the dependence on imported fossil fuels in the

    International Nuclear Information System (INIS)

    2008-01-01

    Basic characteristics of the market for bioenergy (biomass, biogas and biofuels) in Hungary and consequences for business environment are summarized, based on a SWOT analysis. RES is the priority issue to which a lot of attention is paid both at governmental and private level; private investors should view RES as a new niche for their business activities. Standard approach based on a thoroughly done preparation of the project in terms of profitability and risk assessment is necessary in order to avoid potential financial losses due to changed market conditions or differences between assumptions and business reality. Some recommendations for entry on the Hungarian bio energy market are presented: (1) Generally, look for success stories in the Netherlands first and then look for places where such proved and time-tested technologies could be used in Hungary with respect to local specifics. In such way, you can find market niches where investment can be made or new products can be launched; (2) For retail selling it is appropriate to establish business contacts with existing dealers and associations and offer own products through their distribution network. This scheme has the advantage of low initial costs as well as risks involved; (3) In the case of large investments into equipment complexes using RES it seems more appropriate to refer directly either to municipal authorities on whose cadastre the investment should take place or to specialized consultancy agencies that can support the plan with additional information on legal requirements, national programmes supporting RES or available technology. Of course, direct collaboration with well-established local partner can be beneficial for both sides too; (4) If you want to receive up-to-date information on particular aspects of the biomass market in Hungary, you can refer to some governmental organisations associations referred in the key contact addresses

    Hungary supplies only half of its energy requirements from domestic resources and is very dependent upon imports of oil, natural gas and electricity to meet the current demand. In planning to reduce the dependence on imports, nuclear technology is considered an important element in the long-term energy strategy. To this end, an aggressive nuclear electricity generation program is being implemented with four 440 MWe units now operating and two 1000 MWe units committed. However, nuclear technology must be used in other energy sectors if the goal of long-term energy independence is to be achieved. On the demand side, 30% of the primary energy is consumed in the public sector, the major component being residential heating. Of the 3.7 million apartments in Hungary, 500 000 benefit from being connected to municipal district heating systems that use natural gas or oil as the energy base. This is, therefore, another significant energy sector that is amenable to using nuclear technology to substitute for imported oil and natural gas. In assessing alternative nuclear heat sources, a joint study was undertaken between Canada and Hungary to determine the feasibility of using the SLOWPOKE Energy System that has recently been developed. The SLOWPOKE Energy System is a benign nuclear heat source designed to supply 10 thermal megawatts in the form of hot water for local heating systems in buildings and institutions.

    Hungary, a forerunner in Eastern reforms, has boldly privatized its energy sector with foreign capital. While in the west liberalization resulted in electricity abundance and dramatic tariff cuts, in Hungary as a result of asymmetric market opening it brought excess capacities, transparent cost base prices, but lower tariffs are still ahead. Foreign investors made the branch profitable and are planning to expand capacities. (author)

    The EurObserv'ER policy profiles give a snapshot of the renewable energy policy in the EU Member States. In Hungary, electricity from renewable energy sources is supported by a feed-in-tariff or a market ('green') premium, depending on the capacity and energy source. Household-sized power plants up to 50 kVA can benefit from net metering. In general, subsidy programmes also promote the use of renewable energy sources in the electricity and heating sector. The main support scheme for the use of renewable energy in the transportation sector is a quota system supplemented by a reimbursement of excise duty

    Hungary, due to its geographical location is a convenient region for illegal transit of nuclear material between source and target countries. In recent years nine cases have became known and altogether 21.7 kg depleted, 4.6 kg natural, and 2.5 kg low enriched uranium have been confiscated. A brief summary is given of possible origin of the illicitly transported radioactive material. The most important elements of the security of sources including the national and accounting system of radioactive material and the intervention plans are discussed. (author)

    The objective of this study is the evaluation of the mitigation effect of the upland field on the regional intrinsic environment, considering the crop growth stages. FAO Penman-Monteith method is introduced for calculation of the reference evapotranspiration. The crop transpiration and the soil surface evaporation in the upland fields are separately estimated using the crop coefficients, considering the crop growth stages. The ratios of the crop transpiration and the soil surface evaporation in the water consumption change drastically with the crop growth stages. To evaluate the mitigation, effect of the upland field, the latent heat fluxes in the sugar cane field and bare field are estimated during the crop growth period. The deference of the latent heat fluxes in the sugar cane field and the bare field is not marked in the initial crop growth stages. However, in the sugar cane field, the latent heat flux increases drastically, with the sugar cane growing. In the mid-season stage, the latent heat flux is larger than the net radiation. These results indicate that the crop field has the large mitigation effect on the environment, and the efficiency changes with the various factors, including the crop types, the crop growth stages, the cultivation condition, and so on

    One of basic problems of the transition in the energy economy is, how far the process of liberalisation and privatisation could go, i.e. to what extent the control of state/government would be given up, and how the breakdown of the commanding positions of the government would be managed. The transition in the energy sector toward a market economy is characterised by restructuring the regulatory framework of the energy industry, changing the operational structure of the sector and profound reshaping of ownership structures of the enterprises. In Hungary the government, being convinced of the importance of the implementation of the market forces, in 1991 made the first step on the way of restructuring the energy sector in order to increase economic efficiency, to enable companies to react to market forces and to privatise them. Parallel and partly after the restructuring, a profound modification of legal and regulatory framework took place and finally a relatively large scale of privatisation has newly emerged, which will continue in future, too. The process of the energy sector liberalisation in Hungary has a stop and go character and the game is not over. The process can be characterised by institutional restructuring in the energy sector (coal, oil/gas, power ), which is the basic condition for market liberalisation and privatisation, and by the creation of an appropriate environment (regulatory framework, pricing policy, etc. ) for the smooth implementation of the liberation process(author)

    In Hungary, cross-national migration in dental care was performed rather by patients from abroad instead of the domestic dentists' migration for working abroad. Actually, this tacitly realized and so-called dental tourism experienced two basic changes. The National Medical Tourism Ltd. arranged the First Conference for Development of Dental Tourism on 21 April 2011. Hungary's prime minister addressed the meeting and finally signed an agreement with the organizing Ltd. about governmental financial support for development of dental tourism. On the other hand, Germany and Austria deleted all restrictions against the free cross-national workforce migration since 1 May this year. For understanding and prognosis of dentists' future migration, it is inevitable to collect and analyse relevant data of the previous years. This study is presenting data obtained from January 1, 2006 to December 31, 2010. According to the net outcome, the dentists' human resource system was balanced down to the end of 2010. However, this state is unsure even for the near future, thus preventing the deficit of dentists all necessary measures must be taken to keep up the present level of the domestic dentral service.

    Full Text Available Aims, tasks and priorities of medium term development plans of national waste management were defined in the National Waste Management Plan, which was made for the period of 2003–2008 in Hungary. Supporting of the European Union is indispensable for carrying out of plan. The most important areas are related to the developing projects of municipal solid waste treatment (increasingthe capacity of landfills, accomplishment of the infrastructure of selective waste collection, building of new composting plants. The national environmental policy does not focus sufficiently on the prevention of waste production. Due to the high expenses of investment and operation the energetic recovery and the incineration of municipal solid waste do not compete with the deposition. We inclined to think that the waste management of Hungary will be deposition-orientated until 2015. The main problems to the next years will be the lack of reprocessing industry of plastic and glass packaging waste. The high number of to-be-recultivated landfills and the attainability of necessary financial sources are also serious problems. There are many questions. What is the future in national waste management? How can we reduce the quantity of dumped waste? What are challenges of national waste management on the short and long term?

    Full Text Available Century-long traditons of art trade in Hungary are strongly connected to the capital, famous, elite auction houses and galleries are concentrated in the downtown area of Budapest. Although art market in Hungary is capital-centered, remarkable amount of art trade takes place in the countryside too. This study aims to give insight into the presence of the different types of art trade (antique shops, second-hand book stores, art galleries and auction houses in rural settlements, compared to the characteristics of art trade in Budapest. The research – based on primary data collection – reveals the social, economic, and cultural factors which explain the regional differences in art trade. During the field work in Budapest, semi-structured interviews were conducted with art gallery owners, auctioners, and antiquarians. The penetration index (PEX which was applied in the case of researches in the countryside shows the rate in which the different types of art trade are present in settlements of different sizes. The results are demonstrated on the map with the help of the Mapinfo 12.5 software.

    According to the Directive 2009/28/EC of the European Parliament and of the European Council on the promotion of the use of energy from renewable sources the target for the share of energy from renewable sources in gross final energy consumption in the year 2020 for Hungary is 13%, whereas in 2012 it reached 9,8%. Hungarian renewable electricity meets the support in shape of feed-in tariffs. In the aspect of transport the main means of support for the energy from renewable sources is a quota system. The connection of renewable energy plants to the grid will be ranked as a priority. The costs for the connection of renewable energy plants to and the expansion of the grid are borne either by the plant operator or by the grid operator, depending on certain criteria. There are a number of policies intending to promote the development, installation and use of RES installations. However, some policies are currently not available due to exhausted funds of the related subsidy programs. This report monitors the policy changes after the release of the 2013 Progress Report for Hungary and is regularly updated.

    This report studies the cost and benefit of implementing a specific energy conservation programme in Hungary. It considers the possible reduction in damage to public health, materials and crops that may be obtained by reducing the emission of important air pollutants and examines how the programme contributes to reduced emission of greenhouse gases. The measures are described in the National Energy Efficiency Improvement and Energy Conservation Programmes (NEEIECP), a programme elaborated by the Hungarian Ministry of Industry and Trade and accepted by the Government in 1994. The energy saving expected from the programme is about 64 PJ/year. Possible benefits were estimated by the use of monitoring data and population and recipient data from urban and rural areas in Hungary together with dose response functions and valuation estimates mainly from western studies. The main benefits of reducing the concentration of pollutants are found in the health sector, the most pronounced effect being less chronic respiratory deceases. Reduced premature mortality is also important. It is calculated that the annual benefit on public health alone probably exceeds the implementation costs of the programme. In addition, the maintenance and replacement costs for building materials have decreased. The damage to crops due to ozone is large, but a significant improvement in Hungary depends upon concerted action in several countries. 68 refs., 9 figs., 14 tabs.

    Full Text Available The Hoopoe is a widespread species in Hungary with the strongest populations on the Great plains. The fact that in 2015 it became ‛The Bird of the Year’ in Hungary offers the possibility to summarise the information about the distribution, population size, dispersion, migration as well as the nature conservation status of the Hoopoe population breeding in Hungary. In the period of 1999–2014 the number of breeding pairs and trend of population level was estimated based on the Common Bird Census database. The population size was estimated as 13,500–17,500 pairs with a stable trend (slope=−1.3%, SE=2.5% over 1999–2014. There is very limited information on migration from bird ringing, only 8 recoveries between 1928–1963 indicate, that the Hungarian population is migrating on a south-southeast direction in autumn, wintering in the eastern parts of the Sahel, possibly in Chad and Sudan and migrates back in spring following a loop migration pattern further to the east. The main conservation issues are agricultural intensification impacting feeding possibilities, lack of nesting cavities and hunting during migration.

    Human activities have substantial effects on climate system. It has already accepted that change in the long-term climatic mean state will have significant consequences in the global economy and society, but the most important effects of climate change may come from changes in the intensity and frequency of climatic extremes. It is therefore of great interest to document the extremes of surface wind that could assist in estimating the regional effects of climate change. The research presented is based on 34-year-long (1975-2008) wind (speed, direction, and wind gust) data sets of 36 Hungarian synoptic meteorological stations. After processing (including digitalisation of old instrumental records, quality control and homogenisation of wind time series) the measured wind data sets, time series and complex wind climate analysis were carried out. Spatial and temporal distributions of mean and extreme wind climate characteristics were estimated, wind extremes and trends were interpolated and mapped over the country. Finally, measured and reanalysed (ERA40) wind data were compared over Hungary, in order to verify not only the validity of ERA40 reanalysed data sets, but the adaptability of climate simulation results in estimation of regional climate change effects.

    To determine the contribution of clinical trials to the gross domestic product (GDP) in Hungary. An anonymous survey of pharmaceutical companies and clinical research organizations (CROs) was conducted to estimate their clinical trial-related employment and revenues. Clinical trial documents at the National Institute of Pharmacy (NIP) were analyzed to estimate trial-related revenues at health care institutions and the value of investigational medical products (IMPs) based on avoided drug costs. Financial benefits were calculated as 2010 US $ purchasing power parity (PPP) values. Clinical trials increased the revenue of Hungarian health care providers by 1 US $65.6 million. The value of IMPs was US $67.0 million. Clinical trial operation and management activities generated 900 jobs and US $166.9 million in revenue among CROs and pharmaceutical companies. The contribution of clinical trials to the Hungarian GDP in 2010 amounted to 0.2%. Participation in international clinical trials may result in health, financial, and intangible benefits that contribute to the sustainability of health care systems, especially in countries with severe resource constraints. Although a conservative approach was employed to estimate the economic benefits of clinical trials, further research is necessary to improve the generalizability of our findings.

    It is important to understand how upland ecosystems of Alaska, which are estimated to occupy 84% of the state (i.e., 1,237,774 km2), are influencing and will influence state‐wide carbon (C) dynamics in the face of ongoing climate change. We coupled fire disturbance and biogeochemical models to assess the relative effects of changing atmospheric carbon dioxide (CO2), climate, logging and fire regimes on the historical and future C balance of upland ecosystems for the four main Landscape Conservation Cooperatives (LCCs) of Alaska. At the end of the historical period (1950–2009) of our analysis, we estimate that upland ecosystems of Alaska store ~50 Pg C (with ~90% of the C in soils), and gained 3.26 Tg C/yr. Three of the LCCs had gains in total ecosystem C storage, while the Northwest Boreal LCC lost C (−6.01 Tg C/yr) because of increases in fire activity. Carbon exports from logging affected only the North Pacific LCC and represented less than 1% of the state's net primary production (NPP). The analysis for the future time period (2010–2099) consisted of six simulations driven by climate outputs from two climate models for three emission scenarios. Across the climate scenarios, total ecosystem C storage increased between 19.5 and 66.3 Tg C/yr, which represents 3.4% to 11.7% increase in Alaska upland's storage. We conducted additional simulations to attribute these responses to environmental changes. This analysis showed that atmospheric CO2 fertilization was the main driver of ecosystem C balance. By comparing future simulations with constant and with increasing atmospheric CO2, we estimated that the sensitivity of NPP was 4.8% per 100 ppmv, but NPP becomes less sensitive to CO2increase throughout the 21st century. Overall, our analyses suggest that the decreasing CO2 sensitivity of NPP and the increasing sensitivity of heterotrophic respiration to air temperature, in addition to the increase in C loss from wildfires weakens the C sink from upland

    Usutu virus (USUV, Flaviviridae) was first reported in Europe in Austria in 2001, where it caused wild bird (mainly blackbird) mortality until 2005. Since 2006 no further USUV cases were diagnosed in the country. However, the virus emerged in other European countries (Hungary, Italy, Switzerland, Spain, Germany and the Czech Republic) between 2005 and 2011. In 2016, widespread USUV-associated wild bird mortality was observed in Germany, France, Belgium and the Netherlands. In this study, we report the results of passive monitoring for USUV in Austria and Hungary between 2010 and 2016. In Hungary, USUV caused sporadic cases of wild bird mortality between 2010 and 2015 (altogether 18 diagnosed cases), whereas in summer and autumn 2016 the number of cases considerably increased to 12 (ten blackbirds, one Eurasian jay and one starling). In Austria, USUV was identified in two blackbirds in 2016. Phylogenetic analyses of coding-complete genomes and partial regions of the NS5 protein gene revealed that USUVs from Hungary between 2010 and 2015 are closely related to the virus that emerged in Austria in 2001 and in Hungary in 2005, while one Hungarian sequence from 2015 and all sequences from Hungary and Austria from 2016 clustered together with USUV sequences reported from Italy between 2009 and 2010. The results of the study indicate continuous USUV circulation in the region and exchange of USUV strains between Italy, Austria and Hungary.Emerging Microbes &Infections (2017) 6, e85; doi:10.1038/emi.2017.72; published online 11 October 2017.

    The status and recent results of experimental nuclear physics in Hungary is reviewed. The basic nuclear sciences, instrumental background and international cooperation are discussed. Personal problems and the effects of the international scientific deconjuncture are described. The applied nuclear and interdisciplinary researches play an important role in Hungarian nuclear physics. Some problems of cooperation of Hungarian nuclear and other research institutes applying or producing nuclear analytical technology are reviewed. The new instrument, the Debrecen cyclotron under construction gives new possibilities to basic and applied researches. A new field of Hungarian nuclear physics is the fusion and plasma research using tokamak equipment, the main topics of which are plasma diagnostics and fusion control systems. Some practical applications of Hungarian nuclear physical results, e.g. establishment of new analytical techniques like PIXE, RBS, PIGE, ESCA, etc. are summarized. (D.Gy.)

    In Hungary there are four main governmental programs, which may result in a decrease of emissions of anthropogenic greenhouse gases (GHGs): (1) National program of energy efficiency improvement and energy conservation, (2) Afforestation program, (3) Volatile organic compounds (VOC) emission reduction program, and (4) Program to reduce the use of ozone depleting substances. These ambitious programs were launched in the beginning of the 90`s, but they have been slowed down because of budgetary problems. The comprehensive action plan for mitigation of GHG emissions should be based on these ongoing programs. These programs should be expanded by further measures and programs in order to fulfill the requirements of the FCCC. In the next sections the results and prospects of the above mentioned programs will be summarized. Also the results of the mitigation study supported by the U.S. Country Studies Program are included.

    Full Text Available Drawing up cultural macro-regions in Hungary is hardly possible as not even two of the highly developed mezo-regions are contacting, not speaking about forming a bloc; they rather constitute a mosaic on the country map. Those on medium cultural level make up two groups, while, though the ones with a low standard are mostly found along the Danube as a single bloc, they are isolated by Pest county, statistically grouped in one region with them, with a genuine cultural level far exceeding the low cluster. Consequently, it is only justified to speak about cultural regions in the sense that, on the whole, Dunántúl is on a higher standard than the eastern half of the country.

    Full Text Available In Hungary organic food market has both demand and supply oriented aspect: several times not necessary products are distributed while the selection and volume of certain products are not satisfactory. Thus our aim was to develop a coordinated benchmark strategy to increase the trade of organic products. To get more details about the Hungarian organic food market we applied the “mystery shopping” method to observe changes in organic food supply and carried out a quantitative survey using a 1,000 member countrywide panel. Our results indicate that organic origin is considered somewhat important for every 4th respondent, while only 3.7% of the interviewees paid attention to put organic food products into their cart. The most serious obstacle is the doubt of surveyed individuals about the authenticity and the alleged benefits of organic products, complete with a high perceived price. “Price” is the most influential factor on shopping decision, but the advantageous “constant quality” and “health benefit” factors are just following it. Most of the respondents stated that they buy organic products directly from the producer (27.4%, but small retail outlets are likewise popular (though to a somewhat lesser extent. In conclusion, there is potential demand for ecological food products in Hungary. Although the proportion of conscious consumers is small; it significantly exceeds the current market share of the products. Consumers should be approached with better prices, smart retailing solutions and through awareness raising.

  8. Population pressure and migration: implications for upland development in the Philippines.

    1988-01-01

    The identification of Philippine upland sites using topographic maps and photographs, the estimation of population from the 1980 census, and the verification of major migration streams was carried out. The upland population numbered 14.4 million persons according to the 1980 Census. After 1948 up to 1960 the movement of people from the Visayas regions to the frontier lands of Mindanao occurred. The 2nd wave of predominantly urbanward migration occurred after 1960, although in the early 1970s some 47,000 migrants moved to the uplands from Metropolitan Manila. The early-period migrants tended to be young males between 20 and 34 years of age. Migrants tended to be 45-54 years old in the period after 1960. The results of 3 macro-migration econometric models indicated that the availability of land in the uplands was the decisive determinant of movement, and in the long distance interregional flows, the actual length of distance traveled emerged as significant. Factors such as population and education at the areas of destination were significant for the shorter, interprovincial flows. At the municipality level land-related variables were more significant than demographic factors. The factors of distance and demographic size accounted for the large variability in migration. 3 villages in the Mount Makiling watershed were used to evaluate circumstances of movement, frequency, and mode of travel, and the socioeconomic correlates such as income, occupation, ownership status, and education. The average age of migrants was 26 years, about 1/2 of them were married, and the rest were single males in 1960-1970. According to a multiple regression model the determinants of migrant incomes were: 1) acquisition of lands of good quality, 2) access to credit for purchase of inputs, 3) increased commercialization of farming activities, 4) promotion of diversified cropping patterns, and 5) planting of perennials.

    Measurement of responses of herpetofauna at isolated wetlands in the Coastal Plain of South Carolina to disturbance of adjacent loblolly pine forest. Many species of isolated wetland herpetofauna in the Southeastern Coastal Plain may tolerate some disturbance in adjacent upland stands. Responses of isolated wetland herpetofauna to upland silviculture and the need for adjacent forested buffers likely depend on the specific landscape context in which the wetlands occur and composition of the resident herpetofaunal community

    Data on greenhouse gas (GHG) emissions caused by forest management activities are limited. Management such as clearfelling may, however, have major impacts on the GHG balance of forests through effects of soil disturbance, increased water table, and brash and root inputs. Besides carbon dioxide (CO2), the biogenic GHGs nitrous oxide (N2O) and methane (CH4) may also contribute to GHG emissions from managed forests. Accurate flux estimates of all three GHGs are therefore necessary, but, since GHG emissions usually show large spatial and temporal variability, in particular CH4 and N2O fluxes, high-frequency GHG flux measurements and better understanding of their controls are central to improve process-based flux models and GHG budgets at multiple scales. In this study, we determined CO2, CH4 and N2O emissions following felling in a mature Sitka spruce (Picea sitchensis) stand in an upland forest in northern England. High-frequency measurements were made along a transect using a novel, automated GHG chamber flux system ('SkyLine') developed at the University of York. The replicated, linear experiment aimed (1) to quantify GHG emissions from three main topographical features at the clearfell site, i.e. the ridges on which trees had been planted, the hollows in between and the drainage ditches, and (2) to determine the effects of the green-needle component of the discarded brash. We also measured abiotic soil and climatic factors alongside the 'SkyLine' GHG flux measurements to identify drivers of the observed GHG emissions. All three topographic features were overall sources of GHG emissions (in CO2 equivalents), and, although drainage ditches are often not included in studies, GHG emissions per unit area were highest from ditches, followed by ridges and lowest in hollows. The CO2 emissions were most important in the GHG balance of ridges and hollows, but CH4 emissions were very high from the drainage ditches, contributing to over 50% of their overall net GHG emissions

  12. Quantification of upland thermokarst features with high resolution remote sensing

    2013-01-01

    Climate-induced changes to permafrost are altering high latitude landscapes in ways that could increase the vulnerability of the vast soil carbon pools of the region. Permafrost thaw is temporally dynamic and spatially heterogeneous because, in addition to the thickening of the active layer, localized thermokarst features form when ice-rich permafrost thaws and the ground subsides. Thermokarst produces a diversity of landforms and alters the physical environment in dynamic ways. To estimate potential changes to the carbon cycle it is imperative to quantify the size and distribution of thermokarst landforms. By performing a supervised classification on a high resolution IKONOS image, we detected and mapped small, irregular thermokarst features occurring within an upland watershed in discontinuous permafrost of Interior Alaska. We found that 12% of the Eight Mile Lake (EML) watershed has undergone thermokarst, predominantly in valleys where tussock tundra resides. About 35% of the 3.7 km 2 tussock tundra class has likely transitioned to thermokarst. These landscape level changes created by permafrost thaw at EML have important implications for ecosystem carbon cycling because thermokarst features are forming in carbon-rich areas and are altering the hydrology in ways that increase seasonal thawing of the soil.

    After Germany and the Czech Republic, Gaz de France (GdF) has decided to export its know-how and technologies about natural gas into Hungary. Thanks to the Hungarian privatization program started in 1995, GdF could obtain the major participation in the Degaz and Egaz companies, two out of the five local distribution companies, and controls 22% of the natural gas distribution in Hungary.

    Full text: Seeds of two short duration but tall upland rice varieties ''PMK 1'' and ''Poongar'', susceptible to lodging, were subjected to mutation breeding in 1988-1989. Dry seeds of these two varieties were treated with 20, 25 and 30 krad of gamma rays and soaked seeds were treated with 40, 50 and 60 mM concentration of EMS. In M 2 generation lodging was measured and a correlation study was made between the angle of lodging and various characters like plant height, length of lower internode, productive tiller number, culm diameter and panicle weight. The angle to which the main tiller can be bent before lodging on the 25th day after flowering was measured by using a protractor. Those plants which lodged at an angle beyond 30 deg. from the vertical plane were classified as lodging. From 60,000 M 2 plants, 78 lodging resistant semi-dwarf mutants and 5 dwarf mutants were selected. As expected, there was generally a negative correlation between internode length and lodging resistance and a positive correlation of culm diameter with lodging resistance. For plant height and tiller numbers, correlations were not so clear. (author)

    "A Canadian upland forest soil profile and carbon stocks database" was compiled in phases over a period of 10 years to address various questions related to modeling upland forest soil carbon in a national forest carbon accounting model. For 3,253 pedons, the SITES table contains estimates for soil organic carbon stocks (Mg/ha) in organic horizons and mineral horizons to a 100-cm depth, soil taxonomy, leading tree species, mean annual temperature, annual precipitation, province or territory, terrestrial ecozone, and latitude and longitude, with an assessment of the quality of information about location. The PROFILES table contains profile data (16,167 records by horizon) used to estimate the carbon stocks that appear in the SITES table, plus additional soil chemical and physical data, where provided by the data source. The exceptions to this are estimates for soil carbon stocks based on Canadian National Forest Inventory data (NFI [2006] in REFERENCES table), where data were collected by depth increment rather than horizon and, therefore, total soil carbon stocks were calculated separately before being entered into the SITES table. Data in the PROFILES table include the carbon stock estimate for each horizon (corrected for coarse fragment content), and the data used to calculate the carbon stock estimate, such as horizon thickness, bulk density, and percent organic carbon. The PROFILES table also contains data, when reported by the source, for percent carbonate carbon, pH, percent total nitrogen, particle size distribution (percent sand, silt, clay), texture class, exchangeable cations, cation and total exchange capacity, and percent Fe and Al. An additional table provides references (REFERENCES table) for the source data. Earlier versions of the database were used to develop national soil carbon modeling categories based on differences in carbon stocks linked to soil taxonomy and to examine the potential of using soil taxonomy and leading tree species to improve

    Paks Nuclear Power Plant is the only nuclear power plant in Hungary covering 38% of electricity consumption in the country. The nuclear electricity production of the four VVER440/213 type units in the year of 1999 was 14096 GWh, the second best result in the history of the company. After very detailed safety analyses Paks NPP started a safety upgrading program in 1996, and today the CDF values of the reactor units reached an internationally accepted value. The operational and safety culture and the level of safety was evaluated and reviewed by different international organizations like the IAEA, WENRA, WANO. Based on the conclusions of these international organizations the Paks plant w111 be ready for EU accession after the completion of the ongoing safety upgrading program. Capacity enhancement as a part of the preparation for the market conditions resulted a power upgrade around 20 MW for all four units. This way a relatively small investment in comparison with new installations resulted more efficient to market nuclear capacity. Last year the cost of a generated 1 kWh electricity was 5.98 Ft, which is still to be decreased in 2000. To upgrade the competitiveness of nuclear generation lots of efforts were done in the areas of plant management cost reduction, man-power efficiency upgrade. Un-bundling of activities not directly related to electricity generation in one hand, and more efficient cooperation with other VVER operators and the Hungarian Power Companies Ltd. in certain areas on the other hand are good examples for efficient steps in economic improvement. The company as one of the electricity producers also should follow the capabilities of producers in the neighboring countries like Slovakia and Ukraine, where electricity production is with government subsidiary. To find the right balance between the necessary investments and the market induced cost reduction is one of the most important task in Hungary in Eastern-Europe especially when the nuclear energy

    Paks Nuclear Power Plant is the only NPP in Hungary. It has four WWER-440 type reactor units. Since 1989, approximately 40-50% of the total annual electricity generation of the country has been supplied by this plant. The fresh fuel is imported from Russia. Most of the spent fuel assemblies have been shipped back to Russia. Difficulties with spent fuel transportation to Russia have begun in 1992. Since that time, some of the shipments were delayed, some of them were completely cancelled, thus creating a backlog of spent fuel filling all storage positions of the plant. To provide assurance of the continued operation, Paks NPPs management decided to implement an independent spent fuel storage facility and chose GEC-Althom's MVDS design. The construction of the facility started in February 1995 and the first spent fuel assembly was placed in the store in September 1997. The paper gives an overview of the situation, describing the conditions leading to the construction of the dry storage facility at Paks and its implementation. Finally, some information is given about the new Public Agency for Radioactive Waste Management established this year and responsible for managing the issues related to spent fuel management.

    1998-01-01

    Hungary has a countrywide early warning radiation monitoring network which consist of about 70 stations in an on-line connection with the Emergency Information Center of the National System for Nuclear Emergency Preparedness. The system consists of a variety of stations and organizations including Hungarian Meteorological Service, Ministry of Environment and Regional Policy operate their own networks which are not connected with the central system, but could in certain cases exchange the data. The overall impression of the early warning for the radiation emergency is very good, as the system is in the 24 hours on-line mode and raise alarm immediately if the measured values exceed the preset limit. It this respect, the organization appears very good and capable (together with laboratory services) to assure reasonable protection of the population. The possibility to measure the radioactivity in the environment, food and water exist through a series of laboratories, which operate throughout the country. Those appear to be reasonably well equipped and both the knowledge and the experience of their staff appear very high. The same applies for the tools and methods used to forecast the impact and the consequences. (author)

  19. Hungary making progress toward free market

    1992-01-01

    This paper reports that the Hungarian government made major progress in reorienting the energy sector toward a market economy in 1991. A study conducted by the International Energy Agency the progress was particularly evident in price reform and restructuring of the Hungarian energy industry. The pace of change has accelerated. Effective with fourth quarter 1991 through 1992 all the main energy enterprises will begin operating under new structures. Assuming that liberalized energy prices are set by suppliers to cover their costs and local governments do not subsidize district heating prices, all energy prices are to be at least at their economic cost level by mid-1992, IEA the. Some prices will be above this level because of sales taxes on gasoline and diesel and taxes on all imported energy. Hungary depends on imports for about half of its primary energy supply. Because domestic production has peaked, the share of imports will rise if consumption, after a likely further decline in the short term, returns to an upward trend

    We measured seasonal average 222 Rn activity concentrations in the air of 60 wine cellars in the Tokajhegyalja and Villany wine regions of Hungary using Radamon type etched track radon detectors. The exposure period was 3 months, matching the seasons of 2003-2004. We also used an ionization chamber-type continuous 222 Rn-monitor (AlphaGUARD PQ222, Genitron Instruments, Germany) to study temporal variations of 222 Rn activity concentration in a selected wine cellar in the Tokajhegyalja wine region. This instruments also recorded temperature, atmospheric pressure and relative humidity data. The etched track detector data revealed that the 222 Rn activity concentrations in the air of wine cellars spread over a wide range, from the ambient outdoor concentration of 6 Bq.m -3 up to 6 kBq.m -3 characteristic of natural caves. The temporal variation of 222 Rn activity concentration in the air of the selected cellar varied inversely with the variation of the atmospheric pressure. Earlier we observed similar phenomena in natural karstic caves connected to the surface with vertical shafts only. This suggests that relatively large volume of pore space of the embedding rock communicates with the volume of the cellar induced by the variation of the atmospheric pressure

  1. Geodiversity and land degradation in Hungary

    2014-05-01

    Geodiversity represents a variety of natural values, but they are threatened by a series of anthropogenic activities and land degradation processes. Their effect depends on the intensity of the processes and the sensitivity of the area in question. As a consequence of land degradation processes not only biodiversity but also geodiversity can be damaged and deteriorated. The appearance of the natural landscape changes and natural processes may not have a decisive role in landscape development any more. Some of the damages are irreversible because fundamental changes happen in the landscape, or the processes having created the original forms are no longer in operation. Small scale land degradation processes may be reversible if nature is still capable of reproducing the original state. The most important land degradation processes are desertification and soil erosion. Mining, waste disposal, urbanisation and construction activities, agriculture, inaccurate forest and water management, tourism, unsuitable land use can also lead to severe land degradation problems. The objective of the paper is to show Hungarian examples to all land degradation processes that threaten geodiversity. The results will be shown on a series of maps showing land degradation processes endangering geodiversity in Hungary. A detailed analysis of smaller study sites will be provided to show the effects of certain land degradation processes on landform development and on the changes of geodiversity. This research is supported by the Hungarian Scientific Research Fund (OTKA), project Nr. 10875.

    In upland environments, quantifying soil loss through erosion processes at a high resolution can be time consuming, costly and logistically difficult. In this pilot study 'A cost effective framework for monitoring soil erosion in England and Wales', funded by the UK Department for Environment, Food and Rural Affairs (Defra), we evaluate the use of annually repeated ground-based photography surveys, processed using structure-from-motion and multi-view stereo (SfM-MVS) 3-D reconstruction software (Agisoft Photoscan). The aim is to enable efficient but detailed site-scale studies of erosion forms in inaccessible UK upland environments, in order to quantify dynamic processes, such as erosion and mass movement. The evaluation of the SfM-MVS technique is particularly relevant in upland landscapes, where the remoteness and inaccessibility of field sites may render some of the more established survey techniques impractical. We present results from 5 upland sites across the UK, acquired over a 2-year period. Erosion features of varying width (3 m to 35 m) and length (20 m to 60 m), representing a range of spatial scales (from 100 m2 to 1000 m2) were surveyed, in upland habitats including bogs, peatland, upland grassland and moorland. For each feature, around 150 to 600 ground-based photographs were taken at oblique angles over a 10 to 20 minute period, using an uncalibrated Canon 600D SLR camera with a 28 mm lens (focal length set to infinity). Camera settings varied based upon light conditions (exposure 100-400 ISO, aperture F4.5 to F8, shutter speed 1/100 to 1/250 second). For inter-survey comparisons, models were geo-referenced using 20 to 30 ground control points (numbered black markers with a white target) placed around and within the feature, with their co-ordinates measured by survey-grade differential GNSS (Trimble R4). Volumetric estimates of soil loss were quantified using digital surface models (DSMs) derived from the repeat survey data and subtracted from a

    Reports of high concentrations of fallout radiocaesium in basidiomycete fruit bodies after the Chernobyl nuclear reactor accident and speculation that fungi could be long-term 137 Cs accumulators led us to ask if fungi could be long-term 137 Cs accumulators. We used six common upland grassland species to try to estimate their importance in the immobilization of 137 Cs. Uptake of Cs by these species ranged from 44 to 235 nmol Cs g − 1d.w. h − 1. Efflux studies indicate that more than 40% of the Cs taken up is bound within the hyphae. We estimate that the fungal component of the soil could immobilize the total radiocaesium fallout received in upland grasslands following the Chernobyl accident

    Upland rice encompasses 12 percent of global rice production area in the lowest yielding ecosystem, produced by poorest farmers with 0.5 ha average operational holdings. Due to subtle selection over long period of time, upland rice has become drought tolerant potential crop and harbors great genetic potential for future water limited rice. It has also precious traits like high pestilent insect resistant possibility and short growing season. In present investigation, 18 new genotypes were tested for upland ecology during Kharif 2013 and 2014, to identify promising genotypes and formulate phenological relationships at phenotypic and genotypic levels and estimate G x E interactions with uncertain weather parameters. The test populations exhibited enough variation to carry on crop breeding research however, genotypes responded differentially to water stress and late season drought with respect to morphological and yield traits. Considering secondary productivity factors (SPF), days to flowering, plant height, panicles per unit area, spikelet fertility and harvest index was observed to be major contributors for water scarce survivals. Biased selection for earliness cause reduction in grain yield due to shortened vegetative phase hence, research is to be focused to minimize the yield penalty associated with earliness. Among the genotypes evaluated, IR-83381-B-B-137-3 and IR-86857-46-1-1-2 was found to be promising for rainfed breeding programme as parent material. Based on results of farmer field and station trials, existing upland rice variety CR 40 is concluded as promising for upland ecology and will be crucial to uplift the economy of poor and marginal farmers of Chhattisgarh.

    1997-01-01

    Hungary and Czechoslovakia in 1977 concluded a treaty for the building of dam structures in Slovakia and Hungary for the production of electric power, flood control and improvement of navigation on the Danube. In 1989 Hungary suspended and subsequently abandoned completion of the project alleging that it entailed grave risks to the Hungarian environment and the water supply of Budapest. Slovakia (successor to Czechoslovakia) denied these allegations and insisted that Hungary carry out its treaty obligations. It planned and subsequently put into operation an alternative project only on Slovak territory, whose operation had effects on Hungary's access to the water of the Danube. In this judgement, the Court found: (1) that Hungary was not entitled to suspend and subsequently abandon, in 1989, its part of the works in the dam project, as laid down in the treaty signed in 1977 by Hungary and Czechoslovakia and related instruments; (2) that Czechoslovakia was entitled ti start, in November 1991, preparation of an alternative provisional solution (called V ariant C ) , but not to put that solution into operation in October 1992 as a unilateral measure; (3) that Hungary's notification of termination of the 1977 Treaty and related instruments on 19 May 1992 did not legally terminate them (and they are consequently still in force and govern the relationship between the Parties); (4) and that Slovakia, as successor to Czechoslovakia became a party the Treaty of 1997.As to the future conduct of the Parties, the Court found: (1) that Hungary and Slovakia must negotiate in good faith in the light of the prevailing situation, and must take all necessary measures to ensure the achievement of the objectives of the 1997 Treaty; (2) that, unless the Parties agree otherwise, a joint operational regime for the dam on Slovak territory must be established in accordance with the Treaty of 1977; (3) that each Party must compensate the other Party for the damage caused by its conduct; (4

    Full Text Available We studied the change of forestland in the Central Russian Upland within the deciduous forest, forest-steppe, and steppe zones using old maps (XVIII-XX cc. and current satellite images. The forest distribution within the Central Russian Upland has been relatively stable during the last 220 years. On average, the decrease in the forested area was small. However, we identified significant changes in certain regions. In the southern part of CRU, the significant increase of the forested land is caused by the forest protection of abatis woodland and afforestation. During the last 100 years, reforestation took place mainly in the Oka basin due to both afforestation and natural reforestation. New forests appeared generally in ravines within all zones. The analysis of the abatis forests changes from the XVIII to XX cc. allowed us to identify forested area within the Central Russian Upland prior to active development.

    Hungary became a Member of the IAEA in 1957 and has participated in the programme of technical assistance and co-operation from its start in 1958. By the end of 1976, Hungary ranked as the fifteenth largest recipient of IAEA technical assistance. Since then, there has been a significant increase in overall technical co-operation activities, and by the end of 1988 a total of over US $9.5 million of assistance had been received by Hungary, making it the fifth largest recipient of all Member States. In view of this situation, a special evaluation review was carried out in 1989 of the IAEA's technical co-operation programme in Hungary over the period 1976-1989. This evaluation review has shown that, simultaneously with the increase in the IAEA's support, there has been a rapid development in Hungary of the national nuclear infrastructure and this has permitted the country to absorb and utilize the assistance provided to the maximum extent. 7 figs

    In Hungary, there are numerous acts and decrees concerning the uranium ore mining remediation, including the aspects of radiation protection and release limits. The most important ones are: Mining Act, Atomic Energy Act, Environmental Protection Act, Water Management Act, Government Decrees No. 115/1993 and 152/1995. For radiation protection regulation the baselines are codified in the Hungarian National Standard MSZ 62/1-1989, while the release limits are prescribed in the order No. 3/1984 of Hungarian Water Authority (OVH), and in the standard MSZ 450/1-1989. According to the above documents, the limits for annual effective dose-equivalent are: (a) 50 mSv for persons occupied in nuclear industry or working with radioactive isotopes, this is relevant to mining and processing of uranium ore, (b) 5 mSv for the critical group of members of the public, in the case of long exposure this value could not exceed 1 mSv/a. In accordance to the EC directives, it is expected that the limit for the public will be decreased soon to 1 mSv/a. Release limits for discharge of natural radionuclides (U, Th, Ra, Rn) in surface water: (a) for uranium maximum 2 mg/dm 3 , (b) for radium-226 maximum 1.1 Bq/dm 3 . There are no general discharge limits for other pollutants in waste water, but the competent authorities may give individual limits if asked. Detailed limits are given only for drinking water for toxic and chemical components. Release limits for discharge of heavy metals are listed in order No. 3/1984 OVH. Of course, numerous licenses and permissions have to be obtained for remediation. The most important ones are the Environmental Protection Permission, based on a detailed environmental impact assessment, and the technical reclamation plans. Numerous authorities are involved in the licensing procedures (e.g. Mining Authority, Environmental Protection Authority, Water Authority, National Municipal Health Authority, etc.). (author)

  9. Impacts of small scale flow regulation on sediment dynamics in an ecologically important upland river.

    Science.gov (United States)

    2015-03-01

    Flow regulation is widely recognized as affecting fluvial processes and river ecosystems. Most impact assessments have focused on large dams and major water transfer schemes, so relatively little is known about the impacts of smaller dams, weirs and water diversions. This paper assesses sediment dynamics in an upland river (the Ehen, NW England) whose flows are regulated by a small weir and tributary diversion. The river is important ecologically due to the presence of the endangered freshwater pearl mussel Margaritifera margaritifera, a species known to be sensitive to sedimentary conditions. Fine sediment yield for the 300-m long study reach was estimated to be 0.057 t km(-2) year(-1), a very low value relative to other upland UK rivers. Mean in-channel storage of fine sediment was also low, estimated at an average of around 40 g m(-2). Although the study period was characterized by frequent high flow events, little movement of coarser bed material was observed. Data therefore indicate an extremely stable fluvial system within the study reach. The implication of this stability for pearl mussels is discussed.

    2013-03-01

    Full Text Available The Hungarian Meteorological Service (OMSZ and General Directorate of Water Management (OVF in Hungary run conventional precipitation measurement networks consisting of at least 1000 stations. OMSZ automated its synoptic and climatological network in 90’s and now more than 100 automatic stations give data every 1-10 minutes via GPRS channel. In 2007 the experts from both institutions determined the requirements of a common network. The predecessor in title of OVF is general Directorate for Water and Environment gave a project proposal in 2008 for establishment of a new hydrometeorological network based on common aims for meteorology and hydrology. The new hydrometeorological network was set up in 2012 financed by KEOP project. This network has got 141 weighing precipitation gauges, 118 temperature - humidity sensors and 25 soil moisture and soil temperature instruments. Near by Tisza-Lake two wind sensors have been installed. The network is operated by OMSZ and OVF together. OVF and its institutions maintain the stations itself and support the electricity. OMSZ operates data collection and transmission, maintaines and calibrates the sensors. Using precipitation data of enhanced network the radar precipitation field quality may be more precise, which are input of run-off model. Thereby the time allowance may be increased in flood-control events. Based on soil moisture and temperature water balance in soil may be modelled and forecast can be produced in different conditions. It is very important task in drought and inland water conditions. Considering OMSZ investment project in which new Doppler dual polarisation radar and 14 disdrometers will be installed, the precipitation estimation may be improved since 2015.

  13. Ghost forest creation and the conversion of uplands to wetlands

    2017-12-01

    Global sea level rise rates began accelerating sharply in the late 19th century, with an approximate tripling in sea level rise rates in many regions of the world. Some portions of the coastal landscape, such as marshes and barrier islands, survive relative sea level rise by natural eco-geomorphic processes that allow them to build elevation vertically and migrate landward. In contrast, adjacent uplands typically occupied by forests and agricultural fields have limited ability to resist the impacts of sea level rise. This portion of the coastal landscape consists of mostly salt intolerant plants, receives little mineral sediment deposition, and rarely builds elevation through the accumulation of soil organic matter. Thus, ghost forests- dead trees surrounded by marshland- are a prominent feature of many low-relief coastal landscapes, and represent a striking visual indicator of upland to wetland conversion. Here, we report preliminary results of several efforts designed to quantify rates and drivers of upland to wetland conversion in the mid-Atlantic region of the United States. Drone based canopy monitoring and ground-based seedling experiments suggest that ghost forests are created by episodic, storm-driven adult tree mortality paired with continuous seedling mortality. Preliminary comparisons between sediment cores and historical photographs from 5 sites in Maryland, Virginia, and North Carolina suggest that modern coastal forest retreat is 2-10 times faster than late-Holocene retreat rates, and that rates have accelerated in most decades since the 1930's. Finally, historical T-Sheet maps suggest that approximately 100,000 acres (400 km2) of uplands have converted to wetlands in the Chesapeake region, and that about 1/3 of all present-day marsh was created by upland drowning since the late 19th Century. Together, these observations indicate rapid coastal transgression, where low-relief, terrestrial portions of the coastal landscape are perhaps more sensitive to

    Quantitative data on long-term soil erosion rates on agricultural land are an essential requirement for the development of effective soil management and conservation strategies. Although several methods to estimate soil erosion exist, the use of 137 Cs and/or 210 Pb as fallout radionuclides for tracing soil movement overcomes many of the limitations of the traditional methods. Recently, the 137 Cs-technique has been widely accepted and is now commonly used for estimating the magnitude of soil loss. Long-term migration of 137 Cs in the Buekkzserc-Cserepfalu-Bogacs triangle area, at the foot of Buekk mountain (NE Hungary) was studied. The samples were analysed for 137 Cs by gamma spectrometry, using a calibrated high-resolution, low background HPGe coaxial detector. Migration of fallout nuclides in an undisturbed stable soil reflects the influence of a range of physico-chemical and biological processes operating in the soil system. (N.T.)

    Full text: A team of International Atomic Energy Agency (IAEA) experts today completed a mission to review nuclear security practices in Hungary. At the request of the Government of Hungary, the IAEA conducted the two-week International Physical Protection Advisory Service (IPPAS) mission that reviewed the nation's nuclear security-related legislative and regulatory framework, physical protection systems at Hungarian nuclear facilities, and security arrangements applied to the transport of nuclear and radioactive materials. The IAEA team was led by Stephen Ortiz of the United States and included nine experts from six nations and the IAEA. The team met in Budapest with officials from the Hungarian Atomic Energy Authority, Hungarian Police Headquarters, National Security Authority and other relevant agencies. They also conducted site visits to the Paks Nuclear Power Plant, the Interim Spent Fuel Storage Facility, the Budapest Research Reactor, the Budapest Training Reactor, the Radioactive Waste Treatment and Disposal Facility and several other locations where high activity radioactive sources are used for different applications. ''At a time where development of a nuclear power programme is more than ever recognised as necessitating a strong commitment to safety, security and sustainability, the example given today by Hungary strengthens the message about the value of applying the IAEA Security Guidance,'' said IAEA Deputy Director General for Nuclear Safety and Security, Denis Flory, who opened the mission. ''Indeed, IPPAS missions, carried out at the appropriate time in the development of a nuclear power programme, provide valuable insights into how best to reach that goal.'' The IPPAS team concluded that nuclear security within Hungary has been significantly enhanced in recent years. The team also identified a number of good practices at the nation's nuclear facilities, and provided some recommendations and suggestions to assist Hungary in the continuing

    The objectives of this study were to (1) analyze the socio-economic characteristics of upland rice farmers, and (2) to analyze the productivity of farming in South Konawe Regency of Southeast Sulawesi Province, Indonesia. The analysis used in this research was combine economic research through quantitative and qualitative analysis. This research was conducted by survey method. The results showed that (1) farmers are generally in productive age, dominated by men, with low formal education level, and moderate family members, (2) upland rice farming is cultivated in medium land area, with fixed costs higher than variable cost, productivity that has been increased but still lower than rice paddy, and the price of rice production is relatively higher than rice paddy production price, and (3) feasible to cultivate dryland rice, and has a high efficiency value.

  5. Mixed grazing systems benefit both upland biodiversity and livestock production.

    Mariecia D Fraser

    Full Text Available With world food demand expected to double by 2050, identifying farming systems that benefit both agricultural production and biodiversity is a fundamentally important challenge for the 21(st century, but this has to be achieved in a sustainable way. Livestock grazing management directly influences both economic outputs and biodiversity on upland farms while contributing to potentially damaging greenhouse gas emissions, yet no study has attempted to address these impacts simultaneously.Using a replicated, landscape-scale field experiment consisting of five management 'systems' we tested the effects of progressively altering elements within an upland farming system, viz i incorporating cattle grazing into an upland sheep system, ii integrating grazing of semi-natural rough grazing into a mixed grazing system based on improved pasture, iii altering the stocking ratio within a mixed grazing system, and iv replacing modern crossbred cattle with a traditional breed. We quantified the impacts on livestock productivity and numbers of birds and butterflies over four years.We found that management systems incorporating mixed grazing with cattle improve livestock productivity and reduce methane emissions relative to sheep only systems. Systems that also included semi-natural rough grazing consistently supported more species of birds and butterflies, and it was possible to incorporate bouts of summer grazing of these pastures by cattle to meet habitat management prescriptions without compromising cattle performance overall. We found no evidence that the system incorporating a cattle breed popular as a conservation grazer was any better for bird and butterfly species richness than those based on a mainstream breed, yet methane emissions from such a system were predicted to be higher. We have demonstrated that mixed upland grazing systems not only improve livestock production, but also benefit biodiversity, suggesting a 'win-win' solution for farmers and

    A forest stand growth and composition simulator (FORAR) was developed by modifying a stand growth model by Shugart and West (1977). FORAR is a functional stand model which used ecological parameters to relate individual tree growth to environment rather than using Markov probability matrices or differential equations to determine single tree or species replacement rates. FORAR simulated tree growth and species composition of upland forests of Union County, Ark., by considering 33 tree species on a /sup 1///sub 12/ ha circular plot.

  7. The role of igneous sills in shaping the Martian uplands

    Science.gov (United States)

    Wilhelms, D. E.; Baldwin, R. J.

    1989-01-01

    Relations among geologic units and landforms suggest that igneous sills lie beneath much of the intercrater and intracrater terrain of the Martian uplands. The igneous rocks crop out along the upland-lowland front and in crater floors and other depressions that are low enough to intersect the sill's intrusion horizons. It is suggested that heat from the cooling sills melted some of the ice contained in overlying fragmental deposits, creating valley networks by subsurface flow of the meltwater. Terrains with undulatory, smooth surfaces and softened traces of valleys were created by more direct contact with the sills. Widespread subsidence following emplacement of the sills deformed both them and the nonvolcanic deposits that overlie them, accounting for the many structures that continue from ridged plains into the hilly uplands. Crater counts show that the deposit that became valleyed, softened, and ridged probably began to form (and to acquire interstitial ice) during or shortly after the Middle Noachian Epoch, and continued to form as late as the Early Hesperian Epoch. The upper layers of this deposit, many of the visible valleys, and the ridged plains and postulated sills all have similar Early Hesperian ages. Continued formation of valleys is indicated by their incision of fresh-appearing crater ejecta. The dependence of valley formation on internal processes implies that Mars did not necessarily have a dense early atmosphere or warm climate.

  8. Transfer of technetium from soil to paddy and upland rice

    Soil-plant transfer factors (concentration ratio between the plant and soil) of technetium in paddy and upland rice plants were obtained from laboratory experiments. The transfer factor is one of the most important parameters for environmental radiation dose assessment. Technetium tracer ( 95m TcO 4 - ) was added to the soil prior to rice cultivation. The transfer factor of technetium for the hulled grains (brown rice) of paddy rice (≤0.0002) was much lower than for that of upland rice (0.021). The transfer factors for both types of hulled grains were much lower than in the leaves. The technetium decontamination rate from hulled grains by polishing was 34%, the percentage of the weight decrease being 12%. The concentration of technetium in the soil solution collected from the paddy rice soil (flooded conditions) decreased rapidly with time due to its adsorption on the soil. In the upland rice soil (non-flooded) solution, the decrease in the technetium concentration was fairly slow. The low transfer factors for the paddy rice plants could be explained by the immobilization of technetium in the flooded soil. The oxidation-reduction potentials (Eh) in the flooded soil decreased rapidly with time. We conclude that technetium tracer added as TcO 4 - to flooded soil is readily transformed to an insoluble form (e.g.TcO 2 ) under the reducing conditions provided by flooding. (author)

    Historical operations at the Hanford Site (Washington State, USA) have released a wide array of non-radionuclide and radionuclide contaminants into the environment. As a result, there is a need to characterize contaminant effects on site biota. Within this framework, the main purpose of our study was to evaluate radionuclide concentrations in bird tissue, obtained from the Hanford Environmental Information System (HEIS). The database was sorted by avian group (water bird vs. upland bird), radionuclide (over 20 analytes), tissue (muscle, bone, liver), location (onsite vs. offsite), and time period (1971-1990 vs. 1991-2009). Onsite median concentrations in water birds were significantly higher (Bonferroni P < 0.05) than those in onsite upland birds for Cs-137 in muscle (1971-1990) and Sr-90 in bone (1991-2009), perhaps due to behavioral, habitat, or trophic species differences. Onsite median concentrations in water birds were higher (borderline significance with Bonferroni P = 0.05) than those in offsite birds for Cs-137 in muscle (1971-1990). Onsite median concentrations in the earlier time period were significantly higher (Bonferroni P < 0.05) than those in the later time period for Co-60, Cs-137, Eu-152, and Sr-90 in water bird muscle and for Cs-137 in upland bird muscle tissue. Median concentrations of Sr-90 in bone were significantly higher (Bonferroni P < 0.05) than those in muscle for both avian groups and both locations. Over the time period, 1971-2009, onsite median internal dose was estimated for each radionuclide in water bird and upland bird tissues. However, a meaningful dose comparison between bird groups was not possible, due to a dissimilar radionuclide inventory, mismatch of time periods for input radionuclides, and lack of an external dose estimate. Despite these limitations, our results contribute toward ongoing efforts to characterize ecological risk at the Hanford Site. - Highlights: → Radionuclides evaluated in bird tissues on the Hanford Site

    Complete text of publication follows. It is well known that the exposure to particulate matter (PM) during school-age, when children are in their growing stage, can have lifelong adverse effects on their health. Because of these facts it is important to analyse PM in such places where children stay in a limited space during long-term periods. An average schoolchild spends at least six to eight hours a day in an indoor environment. Thus the more detailed knowledge of the air parameters of scholastic environments is particularly important. In this study our aim was to measure those parameters which might help the better estimation of the PM impact on the health of the children/students and teachers in autumn winter season in different educational institutions in the centre of Debrecen, Hungary. Two schools (a primary and a secondary grammar) and a kindergarten were selected for the study. Coarse and fine mass concentrations, elemental composition and mass size distributions were determined in selected microenvironments. These were different classrooms, school yards, gymnasiums, a computer lab, a chemical lab and a so-called salt-room. The elemental composition (for Z ≥ 13) was determined by PIXE and the mass concentrations of particulate matter were determined by gravimetry. In the case of the kindergarten two cascade impactors were also deployed to provide size distribution. In all cases the coarse concentrations of PM were higher inside the educational buildings than in the outer air, and every case the PM 10 concentration exceeded the EU air quality standard (Fig. 1). The highest values were measured in the gymnasiums which could be explained by the activities. We observed increased PM concentrations in the lower educational levels. The fine concentration inside the buildings did not differ significantly from the air outside. We did not detect big differences between the indoor and outdoor elemental compositions, but found differences in the elemental

    Full Text Available The aim of this paper is to compare the tax burden on labour income in Croatia, Austria, Greece, Hungary and Poland in 2013. The Taxing Wages methodology has been applied to hypothetical units across a range of gross wages in order to calculate net average tax wedge, net average tax rate, as well as other relevant indicators. When it comes to single workers without children, the smallest tax wedge for workers earning less than the average gross wage was found in Croatia, while Poland had the smallest tax wedge for above-average wages. Due to a progressive PIT system, the tax wedge for a single worker in Croatia reaches 50% at 400% of the average gross wage, equalling that of Austria, Greece and Hungary. Tax wedges for couples with two children show a similar trend.

    To review strategies of transnational tobacco companies (TTCs) at creating a favourable advertising environment for their products in Hungary, with special regard to efforts resulting in the liberalisation of tobacco advertising in 1997. Analysis of internal tobacco industry documents relevant to Hungary available on the World Wide Web. Transcripts of speeches of members of the Parliament during the debate of the 1997 advertising act were also reviewed. The tobacco companies not only entered the Hungarian market by early participation in the privatisation of the former state tobacco monopoly, but also imported theirsophisticated marketing experiences. Evasion and violation of rules in force, creation of new partnerships, establishment and use of front groups, finding effective ways for influencing decision makers were all parts of a well orchestrated industry effort to avoid a strict marketing regulation for tobacco products.

    Management of forest carbon (C) stocks is an increasingly prominent land-use issue. Knowledge of carbon storage in tropical forests is improving, but regional variations are still poorly understood, and this constrains forest management and conservation efforts associated with carbon valuation mechanisms (e.g., carbon markets). This deficiency is especially pronounced in tropical islands and low-lying coastal areas where climate change impacts are expected to be among the most severe. This study presents the first field estimate of island-wide carbon storage in ecosystems of Oceania, with special attention to the regional role of coastal mangroves, which occur on islands and coastal zones throughout the tropics. On two island groups of Micronesia (Yap and Palau), we sampled all above- and belowground C pools, including soil and vegetation, in 24 sites distributed evenly among the three major vegetation structural types: mangroves, upland forests, and open savannas (generally on degraded lands formerly forested). Total C stocks were estimated to be 3.9 and 15.2 Tg C on Yap and Palau, respectively. Mangroves contained by far the largest per-hectare C pools (830-1218 Mg C ha(-1)), with deep organic-rich soils alone storing more C (631-754 Mg C ha(-1)) than all pools combined in upland systems. Despite covering just 12-13% of land area, mangroves accounted for 24-34% of total island C stocks. Savannas (156-203 Mg C ha(-1)) contained significantly lower C stocks than upland forests (375-437 Mg C ha(-1)), suggesting that reforesting savannas where appropriate has high potential for carbon-based funding to aid restoration objectives. For mangroves, these results demonstrate the key role of these systems within the broader context of C storage in island and coastal landscapes. Sustainable management of mangrove forests and their large C stocks is of high importance at the regional scale, and climate change mitigation programs such as REDD+ could play a large role in

    The annual and monthly distributions of congenital abnormalities and pregnancy outcomes as confounding factors were evaluated in Hungary in reflection of the accident at the Chernobyl reactor. The different congenital abnormality entities and the components of fetal radiation syndrome did not show a higher rate after the Chernobyl accident in the data-set of the Hungarian Congenital Abnormality Registry. Among confounding factors, the rate of induced abortions did not increase after the Chernobyl accident in Hungary. In the 9th month after the peak of public concern (May and June, 1986) the rate of livebirths decreased. Three indicator conditions: 15 sentinel anomalies as indicators of germinal dominant gene mutations, Down syndrome as an indicator of germinal numerical and structural chromosomal mutations, and unidentified multiple congenital abnormalities as indicators of germinal dominant gene and chromosomal mutations were selected from the material of the Hungarian Congenital Abnormality Registry. Diagnoses were checked, familial and sporadic cases were separated and only the sporadic cases were evaluated. The analysis of indicator conditions did not reveal any measurable germinal mutagenic effect of the Chernobyl accident in Hungary

    To describe the impact of the Traumatic Brain Injury management guideline introduction in Hungary. Hospital discharge records (HDR) including age, gender, codes of interventions applied, ICD codes of diagnosed disorders of patients admitted between 01/01/2004 and 31/12/2010 with the diagnosis of intracranial injury (S06 by ICD10) from every inpatient institution in Hungary were collected from the database of National Health Insurance Fund (NHIF). The Case Fatality Ratios (CFR) for one week, one month and six months were calculated for the periods before and after the guideline introduction. The change of CFRs was applied as indicators for change of clinical quality elicited by the guideline. The centers together at one week, one month and six months had pre-guideline introduction CFRs of 23.4%, 37.7% and 47.5% and post-guideline introduction CFRs of 22.1%, 39.1%, and 50.0% respectively. The secondary institutions together at one week, one month and six months had pre-guideline introduction CFRs of 21.5%, 34.8% and 46.3% and post-guideline introduction CFRs of 21.9%, 37.0%, and 48.9% respectively. None of the CFRs showed significant change. The effectiveness of TBI management guideline adaptation in Hungary is poor. Without supportive financing and external auditing system, guideline introduction alone cannot achieve standard clinical practice and a reduction in CFR.

    The article aims to examine the relationship between road transport and macro economy, especially the use of fossil energy in transport sector. Nowadays environmental pollution is a key issue on the EU level as well as in Hungary. Lots of effort have been already done in order to decrease emissions in road transport, but a lot more need to be done. The article aims to prove that the only possible solution is technological innovation in order to reach emission reduction target without decline of the GDP. The basic idea is to ensure sustainable development, to decrease environmental pollution in road transport without harming the economy. In the EU and in Hungary road vehicles are powered by fossil fuelled internal combustion engines. This paper aims to analyse the role of the fossil fuel-based road transport sector within the economy with the usage of constant elasticity substitution (CES) production functions. Authors have built CES production function for Hungary. Parameters were calculated based on the validated model.

  8. The current situation of uranium mining in Hungary

    The paper describes the history of uranium production in Hungary. It focuses on the Mecsek Ore Mining Company, now known as Mecsekuran Limited, and its relationship with the Hungarian Government. From the start of uranium production in 1963 until May 1989 all production was exported to the Soviet Union under a bilateral contract. In exchange the Soviet Union agreed to provide fabricated fuel for the future Hungarian nuclear power plant. In May 1989 the Government of Hungary announced closure of its uranium mining operations because of the high cost of production. The paper describes the history of events since 1989, as well as the current plans to terminate all uranium production by 31 December 1997. The Mecsek Mountains lie in the southern part of Hungary, west from the Danube, about 30 km from the former Yugoslavian border, and north from the city of Pecs. Its eastern side is built up from medieval limestone and dolomites, while the western part is from sandstone and clay from the geological Paleozoic. In the eastern part high quality cokeable coal has been mined for more than 200 years, east from the city of Pecs; and in the western part uranium ore was discovered and the mining began only a few decades ago.

    Full Text Available Lameness in dairy cattle is the third most expensive outbreak after mastitis and reproductive disorders. 25 Holstein-Friesian herds in Hungary were observed for two years to estimate the impact of different trimming methods and managements for the controll of the incidence of lameness. Professional trimming was found to be more effective on farms with no nutritional disorders and where refurnishment works were carried out. The greatest decrease in the prevalence of lameness was observed on farms which provided professional trimming, effective footbathing, improved walking and resting surfaces and which treated severely lame cows between regular trimmings. The greatest increase in occurrence of lameness was reported on farms with on-farm trimmers and where building projects were carried out and nutritional disorders found.

  11. Assessing the continuity of the upland sediment cascade, fluvial geomorphic response of an upland river to an extreme flood event: Storm Desmond, Cumbria, UK.

    Hillslope erosion and accelerated lake sedimentation are often viewed as the source and main storage elements in the upland sediment cascade. However, the continuity of sediment transfer through intervening valley systems has rarely been evaluated during extreme events. Storm Desmond (4th - 6th December, 2015) produced record-breaking rainfall maximums in the UK: 341.4 mm rainfall was recorded in a 24 hour period at Honister Pass, Western Lake District, and 405 mm of rainfall was recorded in a 38 hour period at Thirlmere, central Lake District. The storm was the largest in a 150 year local rainfall series, and exceeded previous new records set in the 2005 and 2009 floods. During this exceptional event, rivers over topped flood defences, and caused damage to over 257 bridges, flooded over 5000 homes and businesses, and caused substantial geomorphic change along upland rivers. This research quantifies the geomorphic and sedimentary response to Storm Desmond along a regulated gravel-bed river: St John's Beck. St John's Beck (length 7.8 km) is a channelised low gradient river (0.005) downstream of Thirlmere Reservoir, which joins the River Greta, and flows through Keswick, where major flooding has occurred, before discharging into Bassenthwaite Lake. St John's Beck has a history of chronic sediment aggradation, erosion and reports of historic flooding date back to 1750. During Storm Desmond, riverbanks were eroded, coarse sediment was deposited across valuable farmland and access routes were destroyed, including a bridge and footpaths, disrupting local business. A sediment budget framework has been used to quantify geomorphic change and sedimentary characteristics of the event along St John's Beck. The volume and sediment size distribution of flood deposits, channel bars, tributary deposits, floodplain scour, riverbank erosion and in-channel bars were measured directly in the field and converted to mass using local estimates of coarse and fine sediment bulk densities

    Estimates of the annual incidence of various osteoporotic fractures in Hungary only recently became available. Further prospective data are needed in order to get an estimate on the public health impact of osteoporosis. It has been postulated that beyond genetic factors, environmental effects play important roles in determining the peak bone mass. Many of the influential environmental factors and also the normal course of the development of peak bone mass need further investigation in our region, also to explore suspected interregional differences in bone health. This study will take place in a centre as participant of a multicentre international population study and aims to draw a random sample of the minimum of 105 persons of both sexes from the urban population (15 to 50) of Debrecen, a town of 220 thousand inhabitants in the Eastern region of Hungary and measure bone density of the spine, hip and total body using isotope related techniques. Further goal is to review major lifestyle variables, such as nutrition and exercise. Laboratory markers of bone metabolism will be assayed and bone samples obtained from victims of accidents to analyze bone quality and elemental composition. Alternative bone sites, such as teeth and oral alveolar bone will be also considered sources of bone samples for comparison to other bone regions. The duration of the study will be 4 years and the study subjects will be followed by repeated measurements and clinical assessment. The data will be collected and analyzed according to a common protocol supported by the IAEA. This makes possible comparing data from the participating countries. Experiences of previous work in this Institute on similar subject is also reviewed briefly. (author)

  13. Will blocking historical drainage ditches increase carbon sequestration in upland blanket mires of Southwest England?

    Peat soils in the United Kingdom are estimated to store a minimum of 3,121Mt C (Lindsay, 2010). Despite being such a large carbon store the annual imbalance between uptake and release is small and susceptible to change in response to land management, atmospheric deposition and climate change. The upland blanket mires of Southwest England have been subject to extensive drainage and are particularly vulnerable to climate change as they lie at the lower edge of the peatland climatic envelope. The Mires-on-the-Moors project, funded by South West Water will restore over 2000 hectares of drained mire by April 2015. Herein, we question whether this restoration, which will block historical drainage ditches will allow the blanket bogs of Exmoor and Dartmoor National Parks to recover their ecohydrological functionality. We hypothesise that such mire restoration will increase the resilience of these ecosystems to climate change and will return these upland mires to peat forming/carbon sequestering systems. A method is proposed which aims to understand the processes driving gaseous carbon exchange and peat formation in an upland blanket bog and quantifies the effect restoration has on these processes. We propose to measure the spatial variation in gas fluxes with respect to structural features of the mire; drainage ditches and nanotopes. The role of vegetation; the community composition, phenology and health will be explored as well as environmental variables such as water table depths, temperature and photosynthetically active radiation. Importantly, the experiment will partition below ground respiration to assess the environmental controls and effect of restoration on autotrophic and heterotrophic respiration separately. Unusually, it will be possible to collect both pre- and post-restoration data for two experimental sites with existing intensive hydrological monitoring (baseline monitoring of water table depths at 15 minute timesteps has been in place for > 1 year at ca

  1. LABOUR MARKET INTEGRATION ISSUES RELATED TO MIGRANTS ARRIVING TO HUNGARY

    Directory of Open Access Journals (Sweden)

    Peter Miklos Komives

    2016-07-01

    Full Text Available The migration flows appearing in the recent years have gained central relevance in Hungary. Previously people were having no opinion about the current situation of issues related to migration but the increased media attention lead to the development of mixed attitudes among people. Some people feel sorry for the families who are coming from the war zones and lost their homes, others have fear of losing their position at work, or their families because of the acts they have heard from the media and they are hostile to the issue of integration whether it is about education or the labour market. According to the statistical data; in the third quarter of 2015, more than hundred thousand asylum-seekers arrived to Hungary, which dropped drastically in the fourth quarter caused by the significant transformation of the asylum process. This study is intended to serve two objectives: first describe the comprehensive picture of labour market attitudes towards migrants and secondly to identify factors that affect the employment of foreigners in Hungary using secondary data sources. Based on this analysis those questions can be formulated, which may constitute a basis for further labour market researches for the integration of migrants. From our point of view there are vital aspects of the migrants’ successful social integration; we have to integrate the migrants who are coming to our country and plan to stay for a longer time to the field of education and the labour market. The social integration of migrants in a country is closely linked to employment, to the integration into the labour market, and in many cases one of the obstacles in this regard is the prejudiced behaviour and negative attitudes towards migrants which manifests itself as the discrimination in the labour market. The results of the European Commission confirm that in Hungary the ethnicity as a variable appears to be the second on the list of the most serious discrimination factors

    Full Text Available Studies of physiological parameters associated with crop performance and growth in different groups of upland rice (Oryza sativa L. may support plant breeding programs. We evaluated the role of gas exchange rates and dry matter accumulation (DMA as traits responsible for yields in a traditional (cv. ‘Caiapó’, intermediate (cv. ‘Primavera’ and modern (cv. ‘Maravilha’ upland rice cultivars. Leaf gas exchange rates, DMA, leaf area index (LAI, harvest indexes (HI and yield components were measured on these genotypes in the field, under sprinkler irrigation. Panicles per m2 and DMA at flowering (FL and heading, as well as CO2 assimilation rates (A were similar across these cultivars. The highest yield was found in ‘Primavera’, which may be explained by (i a two-fold higher HI compared to the other cultivars, (ii greater rates of DMA during spikelet formation and grain-filling, as well as (iii a slow natural decrease of A in this cultivar, at the end of the season (between FL and maturation.

    The objective of the research was to group local upland rice genotypes after being treated with gamma irradiation. The research materials were upland rice genotypes resulted from mutation of the second generation and two parents: Pae Loilo (K3D0) and Pae Pongasi (K2D0) Cultivars. The research was conducted at the Indonesian Sweetener and Fiber Crops Research Institute, Malang Regency, and used the augmented design method. Research data were analyzed with R Program. Eight hundred and seventy one genotypes were selected with the selection criteria were based on yields on the average parents added 1.5 standard deviation. Based on the selection, eighty genotypes were analyzed with cluster analyses. Nine observation variables were used to develop cluster dendrogram using average linked method. Genetic distance was measured by euclidean distance. The results of cluster dendrogram showed that tested genotypes were divided into eight groups. Group 1, 2, 7, and 8 each had one genotype, group 3 and 6 each had two genotypes, group 4 had 25 genotypes, and group 5 had 51 genotypes. Check genotypes formed a separate group. Group 6 had the highest yield per plant of 126.11 gram, followed by groups 5 and 4 of 97.63 and 94.08 gram, respectively.

    Nitrogen (N) deficiency is one of the most yield-limiting nutrients in upland rice growing area in Burkina Faso. A field experiment was carried out from 2008 to 2010 in Farakoba research center with the objective to evaluate 200 upland rice (Oryza sativa L.) genotypes from WAB, NERICA, CNA, CNAX, IRAT and IR lines for N use efficiency. The treatments consisted of three levels of N: low, medium and high at 20, 60 and 100 kg-N h{sup a-1}, respectively. Both grain and straw yield increased with N application. The yields were highest for NERICA and WAB lines compared to the other lines, and this was consistent over the N doses. A large variability was found among the genotypes. Three groups of genotypes were identified according to N use efficiency. The high N use efficiency genotypes were found in WAB and NERICA lines. The N concentration in the shoot at flowering significantly increased with N doses and this was similar for N taken up by genotypes. (author)

  5. Aspects of Anti-Semitism in Hungary 1915-1918

    Directory of Open Access Journals (Sweden)

    Péter Bihari

    2016-10-01

    Full Text Available Before 1914 the vocabulary of anti-Semitism was already present in public discourses in Hungary, but it did not yet represent the central problem of a still ‘liberal Hungary.’ With the First World War, the Hungarian middle classes became the main losers in the social disruption of Hungarian society. 1916 must be seen as the turning point of the social splits and divisions. The former policy of the “Burgfrieden,” or party truce, was undermined by the profound psychological experiences of the war. In this context, old anti-Semitic stereotypes prejudices were reactivated while new ones emerged. Jews, in general, came to be treated as internal enemies, earning huge profits from the war at the expense of Christian Hungarian society that was being ruined. This paper analyzes three stages of growing anti-Semitic agitation in Hungarian society during the war: First, the attacks against the banks around 1916; second, the public debate on the Jewish question in 1917, opened by the publication of the book A zsidók útja [The Path of the Jews] by the sociologist Péter Ágoston and intensified by the “inquiry into the Jewish question” of the journal Huszadik Század [Twentieth Century]; third, the surge of anti-Semitism that began with anti-Semitic speeches in the Hungarian Diet in 1917, leading to a broad anti-Semitic campaign by predominantly Catholic newspapers, in which Otto Prohaszka and Bela Bangha were the leading figures. The thesis is that Hungarian anti-Semitism was far from being a spontaneous outburst of popular feelings. It was fairly well organized and coordinated, mainly by ecclesiastical circles. It was the First World War that proved to be the catalyst, contributing to an extreme anti-Semitism and thereby sealing the fate of “liberal Hungary.”

    The objectives of this work were to identify the most efficient upland rice genotypes in phosphorus (P) utilization, and to verify if P from the seed affects the classification of upland rice genotypes on P uptake efficiency. The experiment was conducted in a greenhouse of the Center for Nuclear Energy in Agriculture (CENA/USP), Piracicaba, Sao Paulo, Brazil, using the {sup 32}P isotope technique, and plants were grown in pots with samples of dystrophic Typic Haplustox (Oxisol). The experimental design was completely randomized with four replications. The treatments consisted of 47 upland rice genotypes and two standard plant species, efficient or inefficient in P uptake. The results were assessed through correlation and cluster analysis (multivariate). The Carisma upland rice genotype was the most efficient in P uptake, and Caripuna was the most efficient on P utilization. The P derived from seed does not influence the identification of upland rice genotypes in P uptake efficiency. (author)

    2008-01-01

    A dramatic drop in employment occurred in Hungary following the change of regime which particularly affected the Roma, people of reduced working ability, and mothers with young children. Alongside economic considerations, the prejudices of employers and discrimination in employment constitute the most significant obstacles to returning to the workplace. The poor mental and physical health of these groups further reduces their chances of finding employment. Only legislation exists to manage the problem, which-in the absence of other interventions-has not brought a breakthrough in the employment of these groups in either the state or local governments or in private spheres.

    A series of top-soil samples of 14 paddy fields and 10 upland fields in Japan, were annually collected during more than 30 years, to be examined in the contents of {sup 137}Cs. The data, which were obtained by the use of a gamma spectrometric system, received some statistical treatments to distinguish the annual decline of {sup 137}Cs contents from deviations. Then the authors calculated `residence half-time of {sup 137}Cs` within top-soil, and `eluviation rate of {sup 137}Cs` from top to the sub-layer of the soil. The following nationwide results were obtained irrespective of paddy or upland field: (1) The `apparent residence half-time` was estimated as 16 - 17 years. This consists of both effects of eluviation and nuclear disintegration. (2) The true residence half-time` was reported as 41 - 42 years. This depends on the eluviation speed of {sup 137}Cs exclusively, because the influence of nuclear disintegration has been compensated. (3) The eluviation rate of {sup 137}Cs from top-soil down to the sub-soil was 1.6 - 1.7% per year. (4) The ratio of distribution of {sup 137}Cs between top-soil and the sub-soil was estimated to be 6:4 as average at the date of 1996. (author)

  17. 'Vacation for your teeth' - dental tourists in Hungary from the perspective of Hungarian dentists.

    Kovacs, E; Szocska, G

    2013-10-01

    Hungary has become a popular destination for foreign patients in the last two decades, particularly in dental care. Since 2008, increasing prices in Western Europe coupled with Hungary's accessibility and availability of dental treatment, has meant the country has become a leader in 'dental tourism'. As the quality of care in Hungary is high and prices are more affordable than in Western Europe, and due to the freedom of movement of people, services and goods within the EU, patient flow into Hungary has increased progressively. The aim of this article is to provide comprehensive empirical evidence from the perspective of a recipient country in dental tourism. A questionnaire survey was conducted among Hungarian dentists (n = 273). Qualitative in-depth interviews were conducted with representatives of dental professional bodies (n = 10). Both research methods aimed to elicit dentists' views on the presence of dental tourism - particularly the push and pull factors (for example, source countries, competitors, information sources, patient motivation). The findings show that there are several reasons why Hungary could maintain a leading position in dental tourism. First, the cost/benefit ratio is outstanding. The affordable price and value for money were already recognised in the early 1990s and were appreciated even before Hungary joined the EU. Secondly, the high quality of Hungary's dental profession: a) dental professionals in Hungary are well-qualified dental practitioners who have received high level dental training; b) dental professional standards are up-to-date and often supervised; c) in Hungary dental technology, the quality of materials and equipment used in dental practices is of European level quality. The rate of complications in dental care is around 5%, similar to other European countries. Finally, previous treatment experiences are positive and patient satisfaction levels are high. More and more patients seek care in Hungary, and more and more

    In Hungary, an important form of emergency contraception (EC) is the pill containing 0.75 mg levonorgestrel, which is marketed by Gedeon Richter under the name Postinor in four-pill packages. Women are instructed to take one pill within an hour of any unprotected act of intercourse, up to four pills per month. The nature of the administration requires that women be in possession of the pills before they need them, and, while Postinor is marketed as an EC, the target market is young, unmarried women who experience infrequent intercourse. When it was first offered a decade ago, Postinor gained widespread use in place of contraception. The product was overused and there was a backlash in the medical community. Thus, the manufacturer changed its packaging instructions and removed the original 10-pill package from the market. While the price of the drug is considered prohibitive for use by adolescents, more than three million pills were sold in the past three years in Hungary and more than 60 million pills were sold in over 20 countries. Clinical studies show a failure rate of less than 1% and relatively few side effects (10-20% nausea and 20-40% bleeding) if not more than four pills per month are used. The World Health Organization is currently conducting trials to compare use of Postinor with the Yuzpe method. Results of these trials will be available in 1996.

    According to the current and previous regulation related to the safety use of ionizing radiation, the personnel involved must obtain special qualification in radiation protection. In Hungary the radiation protection training are performed by appropriately certified training centers on basic, advanced and comprehensive levels. Certification of the training centers is given by the competent radiological health/radiation protection authority. The office of the Chief Medical Officer is the certifying authority for advanced and comprehensive levels training, as well as competent Regional Radiological Health Authority is responsible for basic level courses. The content and length of courses are specified in the regulation for all three levels of industrial, laboratory and medical users, in general. Some of the universities, technical and medical oriented are certified for advanced training for students as gradual course. Recently in Hungary there are 47 certified training centers for advanced and comprehensive courses, where the trainers should have a five years job experience in radiation protection and successful completion of comprehensive level course in radiation protection.

    The critical period of stroke management lies between the disease onset and the time of the emergency call, relying on stroke-related knowledge of the population. Public campaigns play a role in spreading relevant health information. Due to the substantial expenses of these campaigns, the assessment of their efficiency is reasonable. We assessed the number of thrombolytic treatments performed in Hungary, subjected to national media coverage and in particular in Budapest, being the location of the Stroke Day campaign, in the period between 2008 and 2015. We compared the change in the daily mean number of thrombolytic treatments performed during the preceding and following day, week, and month. Data were also compared with annual means. No meaningful changes can be seen in the number of thrombolytic treatments on the days immediately following Stroke Days, and casual differences can be seen in the following week. The comparison of the numbers of thrombolytic treatments performed in the postcampaign months with the monthly means in the corresponding years revealed a positive effect in each year except for 2012, 2014, and 2015. Regarding the whole examined period, however, the effect is not statistically significant, neither for data obtained from Hungary nor from Budapest. Better outcomes were observed 1 month after a campaign than more immediately. This can be partly explained by ongoing media coverage in a given period rather than exposure of the public on a single Stroke Day. Copyright © 2018 National Stroke Association.

    Hungary has arrived at an important moment in its energy policy. The Hungarian government has improved energy policies in a number of areas. Still, significant challenges remain. To prepare the country for the full liberalisation of the EU electricity and gas market by July 2007, further steps in market reform are urgently required. At this point in time, there is no clarity about the system under which the market should operate after its full opening. Subsidies are another problem. Even though substantial progress has been made in reforming payments to gas consumers, the overall level of subsidies to producers and consumers of energy needs to be reviewed. This analysis makes recommendations to tackle these concerns and also discusses the potential contribution of energy efficiency to increasing energy security and economic competitiveness. The gas dispute between Russia and Ukraine in January 2006 focused global attention on consumer nations' vulnerability to supply disruptions. The Hungarian government has since placed greater emphasis on diversification of suppliers and has supported the development of new routes to bring gas into Europe. Hungary has dramatically improved its energy efficiency during the last 15 years. Nevertheless, enhanced efficiency, particularly in the field of gas use will continue to play a key role for securing future national energy supplies. This review has identified significant room for progress particularly in the gas-to-power sector, where old power stations need to be replaced, and in the residential sector, where improved thermal performance of Hungarian housing could bring impressive results.

    Medical records of 600 dogs diagnosed with atopic dermatitis were reviewed and evaluated with reference to history, geographical distribution, breed predilection, clinical signs and positive reactions to allergens as determined by intradermal skin testing (IDT) manufactured by Artuvetrin Laboratories. In 66.6% of dogs, the age of onset of atopic dermatitis was between 4 months and 3 years. Dogs living in the garden suburb of Budapest were more sensitive to house dust mites, fleas and moulds, and dogs from the western part of Hungary were more sensitive to weeds than to other allergens (p French bulldog, Doberman Pinscher and Bobtail which were over-represented among atopic dogs compared to the breed distribution of the general dog population of a large city in Hungary. Breeds with verified adverse reaction to food were Cocker spaniels, French bulldogs, Bullmastiffs, Bull terriers, St. Bernards, Tervurens, West Highland White terriers and American Staffordshire terriers (p < 0.05). The clinical signs of atopic dermatitis and their occurrence are in accordance with the data described in the literature.

    Upland rice grown by subsistence farmers in the tropics and subtropics is known to produce very low yields due to it being planted on low fertility soils and under drought-prone conditions. Little information is available on upland rice cultivar differences in response to N and P fertilization in Asia, thus screening for P (PUE) and N use efficiency (NUE) of upland rice genotypes is a necessary first step. The objectives of the study were: (i) to identify upland rice genotypes with root characteristics favorable for efficient N and P uptake and utilization, (ii) to evaluate the selected genotypes for their grain yield, and (iii) to assess the variability of N and P use efficiency in upland rice genotypes grown under field conditions. Several laboratory, glasshouse and field experiments were carried out from 2007 to 2011 at Universiti Putra Malaysia to achieve the above objectives. Fifteen local and 15 upland rice genotypes from WARDA were identified to have long roots, and it was observed that some of the WARDA lines showed longer root length than the local landraces. This is a good trait since it is known that longer root length will enhance the absorption of easily mobile nutrients such as nitrate and potassium. Glasshouse and field evaluation of N use efficiency by these upland rice genotypes showed that high N is utilized (40-80% of applied N), with good grain yield, and P use efficiency is similar to other crops (4-8%).

    In 1988, monitoring of radioactivity in upland lakes was initiated in areas of Ireland which had been subjected to highest deposition following the Chernobyl accident. The monitoring programme was continued in 1989 and extended in 1990 to include 25 lakes in 13 counties. This survey provided a comprehensive national picture of the distribution of Chernobyl contamination in Irish freshwater lakes. In 1991 and 1992, the monitoring programme concentrated on those lakes which had shown highest levels in the 1990 survey. This report details the results of the freshwater lake monitoring programme for the years 1988 - 1992. As assessment of the radiation doses to those consumers who include relatively large amounts of freshwater fish in their diet is also made

  6. The distribution and migration of sodium from a reclaimed upland to a constructed fen peatland in a post-mined oil sands landscape.

    Post-mine landscape reclamation of the Athabasca Oil Sands Region requires the use of tailings sand, an abundant mine-waste material that often contains large amounts of sodium (Na + ). Due to the mobility of Na + in groundwater and its effects on vegetation, water quality is a concern when incorporating mine waste materials, especially when attempting to construct groundwater-fed peatlands. This research is the first published account of Na + redistribution in groundwater from a constructed tailings sand upland to an adjacent constructed fen peat deposit (Nikanotee Fen). A permeable petroleum coke layer underlying the fen, extending partway into the upland, was important in directing flow and Na + beneath the peat, as designed. Initially, Na + concentration was highest in the tailings sand (average of 232mgL -1 ) and lowest in fen peat (96mgL -1 ). Precipitation-driven recharge to the upland controlled the mass flux of Na from upland to fen, which ranged from 2 to 13tons Na + per year. The mass flux was highest in the driest summer, in part from dry-period flowpaths that direct groundwater with higher concentrations of Na + into the coke layer, and in part because of the high evapotranspiration loss from the fen in dry periods, which induces upward water flow. With the estimated flux rates of 336mmyr -1 , the Na + arrival time to the fen surface was estimated to be between 4 and 11years. Over the four-year study, average Na + concentrations within the fen rooting zone increased from 87 to 200mgL -1 , and in the tailings sand decreased to 196mgL -1 . The planting of more salt-tolerant vegetation in the fen is recommended, given the potential for Na + accumulation. This study shows reclamation designs can use layered flow system to control the rate, pattern, and timing of solute interactions with surface soil systems. Crown Copyright © 2018.

    Full Text Available This article is an analysis of the conditions in Austria-Hungary, respectively the Kingdom of Hungary, focused at political and social status of Slovakia (Upper Hungary. The political representation of the Slovak citizens (at about 12 % of the citizens of the Kingdom of Hungary since the begining of the 20th century went through dynamic transformation. This transformation went into the direction of some kind of deviation from the idea of Slovak autonomy within the Kingdom of Hungary. The general frame of the description of conditions of the era Austria-Hungary is based on autoritative researches by Slovak, Hungarian and Anglo-Saxon origin. There were used such scientific methods as analysis and synthesis, concretization, generalization while solving the research tasks. In addition, the paper used the historical-situational method, involving the study of historical facts in the context of the period under review in conjunction with the "neighboring" events and facts. The creation of the own statehood in cooperation with more powerful Czech politics became the new goal of the Slovak politics. This study will emphasize preconditions and development not only within political elites but also within the dimension of public climate of the Slovak part of the Kingdom of Hungary.

    Red imported fire ants (Solenopsis invicta) have negative impacts on a broad array of invertebrate species. We investigated the impacts of fire ants on the upland arthropod community on 20???40 ha study sites in southern Mississippi. Study sites were sampled from 19972000 before, during, and after fire ant bait treatments to reduce fire ant populations. Fire ant abundance was assessed with bait transects on all sites, and fire ant population indices were estimated on a subset of study sites. Species richness and diversity of other ant species was also assessed from bait transects. Insect biomass and diversity was determined from light trap samples. Following treatments, fire ant abundance and population indices were significantly reduced, and ant species diversity and richness were greater on treated sites. Arthropod biomass, species diversity and species richness estimated from light trap samples were negatively correlated with fire ant abundance, but there were no observable treatment effects. Solenopsis invicta has the potential to negatively impact native arthropod communities resulting in a potential loss of both species and function.

    One of the major environmental problems associated with boreal hydroelectric reservoirs such as those found in Canada and other northern countries is the elevated concentrations of mercury (Hg) in fish. A flooding experiment was conducted in northern Ontario to study methyl mercury (MeHg) production/bioaccumulation and greenhouse gas dynamics in impoundments with flooded upland forests of different soil carbon content, moisture and vegetation. The study, entitled Upland Flooding Experiment (FLUDEX) took place in June 1999 at the Experimental Lakes Area (ELA) where three impoundments of 0.7 ha were flooded to a depth of 1 m using oligotrophic lake water. The hydraulic residence time was 10-14 days. Responses to flooding were compared among treatment reservoirs and to previously flooded wetlands. The study included researchers from Canada and the United States who characterized mercury species fluxes from soils, the overall reservoir mass balance for total Hg and MeHg, inorganic Hg and MeHg concentration in zooplankton, benthic invertebrates, emerging insects and fish. Carbon decomposition was also examined. Preliminary results, one year after inundation, show significantly high levels of MeHg concentration compared to the feed water and that of surrounding natural lakes. Outflow samples from the dry forest areas showed the highest concentrations of Hg and MeHg, with lower concentrations from the moist forest. The lowest levels were observed from the outflow from the driest forest reservoir. A rapid pulse of inorganic Hg appears to have been released during the first 2 weeks of flooding. Soil leaching was found to be the main mechanism or inorganic Hg supply while MeHg appears to have been supplied by in situ microbial methylation. It was also shown that forage fish introduced into the reservoir had significantly elevated concentrations of MeHg compared to fish in natural lakes.

    Summary: Soil condition, plant production and ecological protection are most important parts of the sustainable agricultural activity on all over the world nowadays. Soils, their fertility, their content of different macro-, mezo-, micro-, trace elements have almost always dictated the spread of agricultural farmlands, including the plant production-, yield harvest levels and yield element contents possible. The success of agriculturists in the 20th and 21th century, particularly in the Europe has relied on inproved soil fertility managements, appropriate crop production and environmental protection. We can test and improve the situations by using different plant species (Crotalaria juncea L.) x macro nutrients (nitrogen) x chelating agents (Desferal as deferoxamine-mesilate: C25H48N6O8-CH4O3S) methods. Crotalaria has a very potential and important role in soil fertility as a green manure crop in the design of plant rotation to field plant production, in the animal foraging as a fodder-crop with a high protein content (30%) and in the pytoremediation possibilities. Field experiment was carried out on a calcareous chernozem meadow soil (Kunság-region of Hungary, Kunmadaras) in partly of crotalaria experiment series (5 years) in 2001. The agrochemical parameters of the ploughed layer of the region soils were as follows: humus 2.5-3.0%, pH (H2O) 7.7, pH (KCl) 7.0, LE (Lakanen & Erviö 1971 [3])-P2O5 183-218 mg kg-1, LE-K2O 82-115 mg kg-1, LE-Ca 1.3%, LE-Mg 56-60 mg kg-1, LE-Mn 45 mg kg-1 according to soil analysis. Nitrogen (N) x Desferal ("D"-Novartis Pharma AG Basie [7], Switzerland, Suiza 500 mg) x Genotype ("G"-India-University of Agricultural Sciences, Bangalore) x Time (T) experiment involved The N levels were 0, 100, 200 and 300 kg ha-1 year-1, and Desferal 0 and 20 kg ha-1 year-1.

    This report compares alternative methods for valuation of the social benefits of less air pollution. One can estimate such benefits by the economic consequences of less damage caused by pollution or by the willingness to pay for less pollution. As a case study, the report examines an energy conservation programme in Hungary, in which 64 PJ of fossil energy was conserved per year. According to the damage cost approach, the benefits corresponds to 75 million USD per year, divided into 41 mill for health and 33 mill in material damage. The willingness to pay approach yielded a value of 1.9 bill. USD. Most of the difference is attributed to different estimates for chronic distresses and early death. One should not regard the results of the different approaches as alternative answers to the same question. Instead, damage cost and willingness to pay assessments can be considered as necessary components of a macro economic study of environmental policy. 23 refs., 9 figs., 5 tabs.

    to estimate the effects of vegetation, land use patterns and water cycles. Climate change, hydrological and human uses are also leading to riparian, upland, grassland and crop vegetation changes at a variety of temporal and spatial scales, particularly in the arid and semi arid ecosystems, which are more sensitive to changes in water availability than humid ecosystems. The objectives of these studies from the last three articles were to evaluate the effect of water balance on vegetation indices in different plant communities based on relevant spatial and temporal scales. The new methodology of estimating water requirements using remote sensing data and ground calibration with flux tower data has been successfully tested at a variety sites, a sparse desert shrub environment as well as mixed riparian and cropland systems and upland vegetation in the arid and semi-arid regions. The main finding form these studies is that vegetation-index methods have to be calibrated with ground data for each new ecosystem but once calibrated they can accurately scale ET over wide areas and long time spans.

    A construction licence has recently been granted for a Modular Vault Dry Store (MVDS) for spent fuel at the Paks reactor site in Hungary. The store will be used for medium term (50 years) storage of spent fuel from four VVER-440 reactors. It is anticipated that storage capacity for 1350 fuel assemblies will be available by 1996. Two further construction phases will take the capacity to 4950, covering the first ten years of reactor operation. The design provides for further extension to accommodate a total 15000 assemblies, corresponding to 30 years of reactor operation. The MVDS has developed out of the first application of dry store technology to spent Magnox reactor fuel at the Wylfa power station in the United Kingdom 25 years ago. (UK)

    Full Text Available This article provides an outline of talent identification practices and challenges in Hungary. First, it gives a summary of gifted education in the country; then the general challenges of talent identification are introduced: difficulties of defining talent, talent as potential, environmental factors, the role of perseverance and motivation, and individual variety. Later, recent Hungarian identification practices are shown, followed by a summary and a conclusion about how our identification practice should be developed into an investigation of individual characetristics. We propose stronger focus on the use of cognitive profile tests, investigation of interest-based characteristics, the use of observation and dynamic assessment methods, teacher nomination and emphasizing the need for effort. The focus from identification toward investigation exploring individual needs and characteristics to provide the most appropriate pathway for development in the 21st century seems to be a more effective way of talent support than mere selection.

    In addition to conducting field observations, mineralogical, chemical, and micromorphological analyses, and scanning electron microscope studies were carried out to reconstruct soil forming processes in a paleosol profile sequence located in an open-cast lignite mine in North Central Hungary (Visonta, pediment of the Matra Mountains). Based on these investigations, several different, sometimes contradictory processes were identified: bioturbation on various scales, shrinking-swelling, leaching, CaCO{sub 3} and Fe-oxide precipitation, erosion, sedimentation, weathering, clay mineral transformation, clay illuviation, organic matter accumulations, reduction and oxidation, and frost action. Joint occurrence of these phenomena indicates environmental changes during the formation of the studied sequence. Many of these processes overlap and might have occurred several times. The presence of erosional surfaces makes it more difficult to establish the exact age of this complex formation. All observations suggest that sedimentation and soil formation on the Matra pediment were not continuous during the Quaternary Period

    Full Text Available Modern engineer training is not conceivable without knowledge of work psychology and ergonomics. In this paper, we would like to outline the situation of work psychology and ergonomics as well as their changes in Hungary. The technical approach to health and safety is linked to human health care, and, through that, to ergonomics. The traditional notion of ergonomics is the 'ergonomics of scales, levers and pedals', which has now become a field of research helping the development of socio-technical systems. Here, we present the developmental stages of ergonomics, divided into six periods, first, and then the relationship between environmental ergonomics and health and safety. In the last chapter, I shall expound a few details from Hungarian investigations in work psychology, as well as from the activity of prominent academic circles at certain universities.

    2002-01-01

    Black locust (Robinia pseudoacacia L.) was the first forest tree species to be imported from North America to Europe at the beginning of the 17th century. It is the most important fast-growing stand-forming tree species in Hungary . Black locust plantations can be successfully established in response to arange of economic and ecological opportunities. Plantation survival and productivity are maximized by matching the species' growth characteristics with silvicultura l options and land management needs. In the paper the sequence of forest tending operations in black locust stands is proposed, based on results of long-term st and structure and forest yield trials. Implementing good silvicultural plans and models will lead to profitable black locust stands and greater acceptance of the species by land managers. Black locust would also beavery useful species for energy productions as the related research results have been shown in the paper .

  1. Pricing and reimbursement of drugs and medical devices in Hungary.

    2002-01-01

    Similarly to other countries of Central and Eastern Europe, Hungary has witnessed massive diffusion of healthcare technology such as drugs and medical devices since 1990. While substantial new pharmaceuticals, medical devices, and procedures have been liberalized, there has been no proper evaluation or training in their use. Healthcare providers have come to find themselves as entrepreneurs in private practice, while patients are acquiring an increasing awareness as customers of healthcare,demanding services in return for their taxes and contributions. This has led to extremely irrational patterns of investment in technology, with most an obvious waste of resources, while leaving basic needs unmet. Both the National Health Insurance Fund and the Ministry of Finance believe that the current pharmaceutical and medical device bill is too high. However, introducing a more transparent and flexible pricing and reimbursement framework may enable a more efficient allocation of the limited resources to be achieved.

    Full Text Available It is self-evidently true that ceramics form the largest component of the artefact assemblages of the Neolithic and Copper Age of Central and Eastern Europe, yet we are still poorly informed about the final stage of the life of most vessels – their ultimate disposal. In this paper, I wish to consider the ways in which pottery can be studied with respect to disposal and deposition. An assessment of ten different kinds of pottery analysis is made, using site single contexts as the main unit of analysis. I propose that these analyses constitute ways of measuring Bourdieu’s term “habitus”. This contextual analysis is based on examples taken from the Neolithic settlement of Polgar-10, in North East Hungary, excavated by the Upper Tisza Project in 1994.

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

    A methodology has been developed which provides a framework for the assessment of the wider impacts arising from GHG limitation projects, and advice on how to incorporate them into the decision-making framework. The purpose of this report is to apply the methodology to a set of selected GHG limitation projects currently being considered for implementation in Hungary. In total, four GHG limitation projects were selected for application of the methodology. This second phase of the research in Hungary, concentrated on four mitigation options in the household sector: Specifically, the selected GHG limitation projects involve: 1. The installation of new, better insulated windows. 2. The installation of water saving devices on water taps. 3. The installation of active solar cells to prepare domestic hot water. 4. The replacement of traditional light bulbs by compact fluorescent bulbs. This study has shown the potential, as well as the current pratical limitations, of the methodology. The value of the employment created has been estimated by adding gains in income effects with health effects. The environmental effects that have been quantified suggest that the reduction of pollution and associated health effects would be significant. The options that have been investigated are too small-scale to generate distributional impacts or macro-economic effects but the estimated effects on sustainability are positive and significant. The principal policy conclusion that can be drawn from the analysis thus far is that it is imperative to consider indirect effects. It is possible that inclusion of indirect effects will make the net economic cost of an option negative thereby making it much more easy to 'sell' as a policy measure - though the assumptions will have to be made explicit and therefore defensible. It is important for policy makers to note that whilst there is a general pattern of lower economic costs derived from this analysis, the reductions are not uniform and

    To evaluate potential health and economic returns from implementing smoking cessation interventions in Hungary. The EQUIPTMOD, a Markov-based economic model, was used to assess the cost-effectiveness of three implementation scenarios: (a) introducing a social marketing campaign; (b) doubling the reach of existing group-based behavioural support therapies and proactive telephone support; and (c) a combination of the two scenarios. All three scenarios were compared with current practice. The scenarios were chosen as feasible options available for Hungary based on the outcome of interviews with local stakeholders. Life-time costs and quality-adjusted life years (QALYs) were calculated from a health-care perspective. The analyses used various return on investment (ROI) estimates, including incremental cost-effectiveness ratios (ICERs), to compare the scenarios. Probabilistic sensitivity analyses assessed the extent to which the estimated mean ICERs were sensitive to the model input values. Introducing a social marketing campaign resulted in an increase of 0.3014 additional quitters per 1 000 smokers, translating to health-care cost-savings of €0.6495 per smoker compared with current practice. When the value of QALY gains was considered, cost-savings increased to €14.1598 per smoker. Doubling the reach of existing group-based behavioural support therapies and proactive telephone support resulted in health-care savings of €0.2539 per smoker (€3.9620 with the value of QALY gains), compared with current practice. The respective figures for the combined scenario were €0.8960 and €18.0062. Results were sensitive to model input values. According to the EQUIPTMOD modelling tool, it would be cost-effective for the Hungarian authorities introduce a social marketing campaign and double the reach of existing group-based behavioural support therapies and proactive telephone support. Such policies would more than pay for themselves in the long term. © 2018 The Authors

    Full Text Available Hearing the words “international migration”, two things might come to our mind. One of them is the emigration process and the other is the wave of refugees. In our study, we examined the changes of the number of employees emigrating from Hungary from 2000 until today. Nowadays, the examination of the migration potential is an important topic in Hungary, since the rate of Hungarian emigrants started to grow after 2006 and the rate of growth became even faster after 2010. The reason of the acceleration was the opening of the Austrian and German labour market. The actuality of the topic is based on the fact that international emigration merges the labour market’s processes, influences the given country’s employment level, moreover it has an influencing role on the rate of wages. Emigration from a given state has several reasons: natural disasters, war, marginalization, economic reasons, etc. In our study, we examine emigration caused by economic reasons. We have to take into consideration that measuring emigration processes is a difficult task, due to the lack of data. The reason of the deficiency is that those who leave the country, often forget to report their leaving. From 1 March 2013, only the permanent foreign settlement should be reported towards the administration (District Office, Consulate. Earlier, temporary (more than 3 months settlement was also obligatory to be reported. Many of the leaving Hungarians do not report their leaving, however working abroad for more than 3 months should be reported towards social insurance organizations and tax authorities. I would like to emphasise that my migration potential presentation does not show a direct correlation with the actual migration. However, this study might show the expected movement rates and the composition of emigrants.

    Full Text Available In Hungary detailed research work has been carried out since several years to help the process of getting prepared and adapted to the impacts of climate change. The research activities concerned mainly the health impacts of heat waves (excess mortality. Based on the results of the time series statistical analysis of weather variables and daily mortality of Budapest, it was found that a 5º C increase of the daily mean temperature increases of the risk of all cause mortality by 10%; and the risk of death due to cardio-vascular diseases by 12%. The frequency of heat waves has been increasing since the nineties. The most extreme heat wave hit the country in 2007 with an excess mortality around 1100 cases. A three level heat health warning system was launched in 2005 as an action to support adaptation. A significant association was found between global radiation and the increase of melanoma cases. The incidence of melanoma morbidity increased between 2003– 2008, the number of new cases changed from 1854 to 2610. The data of the previous years support that there is an increasing risk of vector borne diseases, as the continuous increase of the incidence of Lyme diseases (15% per year showed it. Although tick-borne encephalitis is present in the country, the incidence of the disease does not show a strong correlation with climate variability. Diseases like West Nile virus and Hanta virus infection appeared and showed an increasing tendency. The vector of Leishmaniasis also appeared in Hungary. Another consequence of climate change is the temporal and spatial change of allergenic plant species. New, invasive plants will appear, the length of pollination has been increasing.

  9. Demographic processes of developmentally peripheral areas in Hungary

    Full Text Available The current study investigates the demographic processes and challenges of the Hungarian developmentally peripheral settlements. Demographic challenges can be regarded as important consequences of the social and economic disadvantages in spatial terms. However, the interrelating negative demographic tendencies cause even more backward situation blocking or hindering the development. The objective of the current analysis is to discover the demographic characteristics of the peripheral settlements, to detect the spatial disparities and to point out the correlation between backwardness and the investigated demographic phenomena with the help of the census databases 1980-2011 and local datasets on Roma population. Using methods of multivariate statistical analysis, seven indicators were selected in order to achieve the goals of the paper. Backward areas are primarily characterized by population decrease with significant disparities, but there were growing communities among them as well. Some small villages in Northern and Southwestern Hungary will foreseeably face complete depopulation within few years. Primarily small sized villages faced intense decrease in rate of natural change, but dynamic population growth was also detected. Migration loss tends to correlate with the extent of peripherality, as increasing values of migration balance accompany decreasing ratio of peripheral settlements in the area. The ratio of elderly population shows an expressively two-faced character, with the extremely aging and very juvenile settlements. The ratios of Roma population reflect the scale of peripherality. Extended ethnic change could be predicted in Northeastern and Southwestern Hungary and near the Middle Tisza valley. Presented demographic processes will make the backwardness of most of the peripheral settlements stable.

    Stroke mortality is extremely high in Central-Eastern European countries. We report basic characteristics of a stroke unit in Eastern Hungary, including age and sex distribution; the proportion of transient ischemic attacks (TIA), ischemic and hemorrhagic strokes; case fatality; application of diagnostic methods; and length of stay for all patients treated with acute cerebrovascular disease over a 12-month period. Records of all patients with acute cerebrovascular disease (n = 522) discharged in 1995 from a stroke unit with a well defined catchment area of 220,000 inhabitants in Eastern Hungary were retrospectively analyzed. Case fatality was 18.6% for all patients and 21.1% after excluding cases with TIA. Computer tomography, duplex carotid ultrasound, cerebrospinal fluid examination and electroencephalography were performed in 79%, 77%, 7% and 2% of the patients, respectively. The database of the university hospital with the same catchment area was electronically searched for patients who were discharged with the diagnosis of stroke from the three departments of internal medicine. Stroke mortality data of the catchment area based on death certificates was obtained from the Central Statistical Bureau. Two hundred twenty-eight stroke deaths were reported in the catchment area in 1995. In the same period 97 stroke deaths occurred at the stroke unit and 76 at the departments of internal medicine. If we aim to treat all patients with acute stroke at the stroke unit, with the present stroke incidence and duration of hospital stay the current capacity of the stroke unit (1 bed per 10.000 inhabitants) should be doubled

    The stress-induced epimutations could be inherited over generations and play important roles in plant adaption to stressful environments. Upland rice has been domesticated in water-limited environments for thousands of years and accumulated drought-induced epimutations of DNA methylation, making it epigenetically differentiated from lowland rice. To study the epigenetic differentiation between upland and lowland rice ecotypes on their drought-resistances, the epigenetic variation was investig...

    Full Text Available Abstract There is a shade factor and low organic matter content of the soil is a problem that needs to be addressed in the development of upland rice cultivation as intercrops in the plantation area. Based on these considerations then one study that needs to be done is to conduct experiments on the effect of shade factor combined with the the provision of the organic material to the some varieties of upland rice that has been recommended nationally. The objective of experiment is to study the influence of shade organic materials and varieties on the growth and production of upland rice. This research using experimental design of Split - Split Plot Design with 3 treatment factors and 3 replications or blocks. The first factor is the treatment of shade with 3 levels shade percentage 0 20 and 40. The second factor is the dosage of organic material consists of 3 levels 0 g polybag 25 g polybag 50 g polybag and 75 g polybag. The third factor is the treatment of varieties consists of 4 types of upland rice varieties Si Kembiri Situ Patengggang Situ Bagendit and Tuwoti. The research results showed that the effect of shade on upland rice varieties decrease number of tillers number of panicles number of productive grains grain production per hill of uplnd rice plants and total sugar content of upland rice plants. Effect of organic matter increases number of panicles number of productive grains grain production per hill of upland rice plants and total sugar content of upland rice plants. It is known that the the variety of Situ Patenggang provides better growth and production compared with three other varieties Si Kembiri Situ Bagendit and Tuwoti in shaded conditions.

    The Upper Mississippi River is thought to provide important stopover habitat for migrating landbirds because of its north-south orientation and floodplain forests. The river flows through the Driftless Area of southwestern Wisconsin and southeastern Minnesota where forests are plentiful, yet forests of the floodplain and Driftless Area uplands differ greatly in landscape setting, tree species composition, and topography. We compared landbird assemblages in these upland and floodplain forests over three springs, 2005–2007, using line-transect surveys at randomly selected areas in and within 16 km of the floodplain. We found more species of both transient and locally breeding migrants per survey in floodplain than in upland forest. Detections of transient neotropical migrants did not differ statistically by habitat. Detections of locally breeding neotropical and temperate-zone migrants and transient temperate-zone migrants were greater in floodplain than in upland forest. Between floodplain and upland forest, assemblages of locally breeding species, including neotropical and temperate-zone migrants (of which some individuals were in transit), differed substantially, but assemblages of transients (including both neotropical and temperate-zone migrants) did not differ as much. Only two species of transient migrants had clear affinities for floodplain forest, and none had an affinity for upland forest, whereas most locally breeding migrants had an affinity for either upland or floodplain forest. Within each spring, however, detections of transient neotropical migrants shifted from being greater in floodplain to greater in upland forests. This intraseasonal shift may be related to the phenology of certain tree species.

    Groundwater connections from upland-embedded wetlands to downstream waterbodies remain poorly understood. In principle, water from upland-embedded wetlands situated high in a landscape should flow via groundwater to waterbodies situated lower in the landscape. However, the degree of groundwater connectivity varies across systems due to factors such as geologic setting, hydrologic conditions, and topography. We use numerical models to evaluate the conditions suitable for groundwater connectivity between upland-embedded wetlands and downstream waterbodies in the prairie pothole region of North Dakota (USA). Results show groundwater connectivity between upland-embedded wetlands and other waterbodies is restricted when these wetlands are surrounded by a mounding water table. However, connectivity exists among adjacent upland-embedded wetlands where water–table mounds do not form. In addition, the presence of sand layers greatly facilitates groundwater connectivity of upland-embedded wetlands. Anisotropy can facilitate connectivity via groundwater flow, but only if it becomes unrealistically large. These findings help consolidate previously divergent views on the significance of local and regional groundwater flow in the prairie pothole region.

    The distribution and transfer of caesium and potassium between soils and vegetation has been investigated by field sampling and experimental studies on soils and vegetation typical of upland grassland in north west England. Total 137 Cs content to a depth of 0.05 m below root matt ranged from 13 000 to 18 000 Bq m -2 . This caesium content derives from three sources: the Windscale accident of 1957, weapons-testing fallout which peaked in the early 1960s, and the Chernobyl accident in May 1986. From 2200 to 6200 Bq m -2 is attributed to the first two sources, and the remainder to Chernobyl. During accelerated growth of vegetation, on monoliths in glasshouse conditions over the winter of 1986/87, 137 Cs was transferred from soil and root matt to new growth, such that concentrations in fresh growth were similar to or higher than those observed in the field during December 1986. Removal of caesium by successive cuts resulted in up to 25% of the original estimated total being removed over a 240 day period. Increased concentrations coincided with the emergence of Carex sp. and Trichophorum caespitosum, as well

    Full Text Available The general objective of the study was to provide current information on grassland communities as deer habitat and its future development plan for a sustainable forage management in upland Kebar, Papua. Quantitative estimation of forage production was carried out by measuring a biomass harvest in fresh weight bases, while occasional observations on ranging deer were done within habitat range with the aid of 7x50 binoculars verified by actual visitation of grazed area. The study indicated that Kebar was the only grazing area of deer varies in low layer vegetation composition that comprised of eleven grass species and five legume species. Imperata cylindrica, Paspalum conjugatum, Themeda arguens, Melinis minutiflora and Cyperus rotundus were identified as food plant of deer in Kebar. Among these species T. arguens, M. minutiflora, C. rotundus and I. cylindrica were the most preferred species consumed by deer. The biomass harvest (species productivity was 30.36 kg/ha fresh weight, while deer food productivity in the grassland was slightly lower (26.70 kg/ha than total productivity of the grassland. The major drainage area is Kasi River, but two other rivers across this valley (Api River, Apriri River are also supply water to the swampy area.

    Organic seston represents food for filter feeders and a mechanism for downstream transport of energy and nutrients. As part of a study assessing the ecological impacts of stream-breeding anuran extirpations, we examined seston dynamics in 2 stream reaches with tadpoles (El Cope) and 2 without (Fortuna) in the Panamanian uplands. All reaches are high gradient with annual average discharge ranging from 46-102 L/s. Samples were collected multiple times per month at various discharges, sieved into fine (98μm) and very fine (1.6μm) fractions, and processed to estimate ash-free dry mass (AFDM), total C, and total N. Average annual concentrations ranged from 0.52- 2.51 mg/L (fine) and 2.04-3.14 mg/L (very fine), and total export ranged from 0.27-7,981 mg/s across all streams. On average, very fine particles comprised 78% of export from El Cope sites and 61% from Fortuna streams. Average total N export ranged from 5.32-30.53 mg/s in El Cope sites and 1.71-6.04 mg/s at Fortuna. Average particle quality (C/N) in El Cope streams was higher (7.6) than Fortuna streams (11.5). Lower export of very fine particles and lower seston quality in Fortuna streams suggests the loss of tadpoles may influence seston dynamics and quality in these systems.

    The conversion of land from its native state to an agricultural use commonly results in a significant loss of soil carbon (Mann, 1985; Davidson and Ackerman, 1993). Globally, this loss is estimated to account for as much as 1/3 of the net CO2 emissions for the period of 1850 to 1980 (Houghton and others, 1983). Roughly 20 to 40 percent of original soil carbon is estimated to be lost as CO2 as a result of agricultural conversion, or "decomposition enhancement". Global models use this estimate along with land conversion data to provide agricultural contributions of CO2 emissions for global carbon budgets (Houghton and others, 1983; Schimel, 1995). Soil erosion rates are significantly (10X) higher on croplands than on their undisturbed equivalents (Dabney and others, 1997). Most of the concern over erosion is related to diminished productivity of the uplands (Stallings, 1957; McGregor and others, 1969; Rhoton, 1990) or to increased hazards and navigability of the lowlands in the late 1800's to early 1900's. Yet because soil carbon is concentrated at the soil surface, with an exponential decline in concentration with depth (Harden et al, 1999), it is clear that changes in erosion rates seen on croplands must also impact soil carbon storage and terrestrial carbon budgets as well. As yet, erosional losses of carbon are not included in global carbon budgets explicitly as a factor in land conversion nor implicitly as a portion of the decomposition enhancement. However, recent work by Lal and others (1995) and by Stallard (1998) suggests that significant amounts of eroded soil may be stored in man-made reservoirs and depositional environments as a result of agricultural conversion. Moreover, Stallard points out that eroding soils have the potential for replacing part of the carbon trapped in man-made reservoirs. If true, then the global carbon budget may grossly underestimate or ignore a significant sink term resulting from the burial of eroded soil.

    Somatic embryogenesis is the formation, growth and development of embryos from somatic cells. Somatic embryo induction is one of the in vitro plant propagation techniques that is very important for plant developmental purposes. Four local upland rice varieties of East Kalimantan, Mayas Pancing, Gedagai, Siam and Serai, were used in this study. A total of 200 explants (mature rice grains) for each varieties were inoculated on MS solid medium supplemented with 1 mg L-1 2,4 Dichlorophenoxy acetic acid (2,4-D) and 0.5 mg L-1 6-Benzylaminopurine (BAP). The results showed that response of each variety differed to embryosomatic induction, indicated by callus induction rate and callus quality, in terms of callus color and structure. The fastest callus formation was sobserved in Gedagai variety (8 days) while Mayas Pancing (13 days) was the latest one. The rate of callus induction varied from 60 to 98.5 %, and Serai variety has the highest callus induction rate. The highest friable callus structure was found in Siam variety (89.1%) and the lowest was in Gedagai (62.5%). Callus color was dominated by the yellowish-white (transparent) on all varieties tested. Most of the callus was potential as embryogenic callus characterized from the nodular and globular of friable callus structure and its yellowish-white color.

Observation of radiation effect was carried out on root and shoot length of M 1 seedlings; plant height, panicle length and number of tiller and seed sterility in M 1 plants. Selection for dwarf and semi-dwarf characteristics were done in M 2 plants, and selected again in M 3 . Observation on radiation effect indicated that 'Seratus Malam' seems to be more resistant than the lowland rice varieties. Increasing doses of radiation caused increasing frequency of chlorophyll mutations as well as chlorophyll mutants. Whereas, selection of dwarf or semi-dwarf in M 2 plants seems that mutant and mutation frequencies decreased as the dose increased. Dose of 0.2 kGy was suitable for selection of dwarf or semi-dwarf plants. Plant height could be influenced by environmental condition. Many of the selected M 2 plants were not really dwarf or semi-dwarf mutants. M 3 evaluation of the selected M 2 plants was really beneficial in the mutant selection. (author)

    Five-parent diallel cross data were analysed following Hayman-Jinks genetic model in order to study pattern of inheritance of staple length, fibre strength, fibre fineness and fibre uniformity of upland cotton. The regression analysis of the F/sub 1/ data revealed that the simple additive dominance model was adequate for genetic analysis. Graphic analysis showed the presence of over-dominance type of gene action in the inheritance e of all the traits. The comparison of array means indicated that varieties Co-2-1 and B-682 had good general combining ability for staple length and fibre strength respectively, whilst CIM-443 showed better general combining ability for fibre fineness and fibre uniformity than the other varieties. The cross combination of Co-2-1 and CIM-443 with B-682 expressed best specific combining ability for staple length and fibre uniformity respectively. Similarly variety B-682 nickel well with DPL 7740-424 for the fibre strength, and coker-307 with CO-2-1 for fibre fineness. The type of gene action controlling inheritance of these characters, and better performance of some of the hybrids suggest that improvement may be possible by developing on appropriate breeding programme.

    Full Text Available Plant breeders must be concerned with the total array of economic characters in their efforts to develop a crop variety acceptable to farmers. Their selection endeavours must therefore take into consideration how changes in one trait affect, simultaneously changes in other economic attributes. The importance of correlations and correlated responses is therefore self evident in plant breeding endeavours. In this study F3 progenies from a cross between two cotton lines SAMCOT-9 x Y422 were evaluated for two years and performance data were used to obtain correlations between nine agronomic and fibre quality traits in upland cotton. The results indicated that plant helght was significantly and positively correlated with seed cotton yield, number of sympodial and monopodial branches, seed index, fibre length and micronaire index. Positive and significant correlations were also obtained between : seed cotton yield, tint percent and fibre strength and fibre length. Significant negative correlations were obtained between : plant height and lint percent ; number of monopodial branches, sympodial branches and lint percent ; fibre length, fibre strength and micronaire index. The correlated responses in the other eight traits when selection was practiced for seed cotton yield in the present study shows that it might be more profitable to practice direct selection for seed cotton yield compared to selecting for seed cotton yield through any of the other traits.

  6. Sunlit Uplands: The Genius of the NICE Reference Case

    Full Text Available The NICE reference case has received widespread acceptance in health technology assessment. The lifetime cost-per-QALY model and constructed claims for product impact have been widely emulated in country-specific guidelines for formulary submission as well as in publications in the leading health technology journals. Unfortunately, from the perspective of the standards of normal science, adherence to the reference case standard means that the claims made are typically non-evaluable. They have to be taken at face value. They may suggest potential evaluable hypotheses for clinical and cost-effectiveness claims, but there is no requirement in the reference case for claims to be put in an evaluable form and for manufacturers to suggest possible protocols for product impact assessment. This is not an acceptable situation. Absent the standards for falsification and replication, which are at the core of the scientific method, we have no idea whether the claims accepted by NICE are right or even if they are wrong. If we accept the reference case paradigm should we conclude that the sunlit uplands of formulary decisions based on non-evaluable simulated claims for cost-effectiveness has been reached? Have we rejected natural selection in favor of intelligent design? Conflict of Interest None Type: Commentary

  7. EFFECTS OF EXCESS URBAN RUNOFF ON WASTE WATER FLOW IN PÉCS, HUNGARY

    Full Text Available Global warming has been leading to climate change that is predicted to cause an increase in the frequency and intensity of rainfall. Urban areas must be designed to cope with the undesired effect and risks associated with stormwater runoff. Stormwater, entering into the sewerage of Pécs, SW Hungary, exerts an extra load on wastewater and sewage transfer in the underground pipeline system. Based on precipitation and pumping station flow data, we identified a strong correspondence between rainfall and flow behavior in Pécs. We also determined the types of foreign waters entering the sewerage according to their source and origin. Our study also indicates that 32% of the entire land area has a low-degree infrastructure for cutting-edge stormwater drainage and management. The results of the current research aid to evaluate the adequate methodology for risk analysis of each sewage catchment. The spatial analysis of waste water system and its physical and human geographical environment became an effective tool to help the local waterworks (Tettye Forrásház Ltd. to estimate potential hazard level in each sewage catchment and allocate and distribute pumping costs and efforts among the pumping stations during spatiallyheterogeneous torrential rainfall events.

    We investigate the relations of early atypical characteristics (perinatal problems, developmental delay, and difficult temperament) and onset-age (as well as severity of) first major depressive disorder (MDD) and first internalizing disorder in a clinical sample of depressed children in Hungary. Participants were 371 children (ages 7-14) with MDD, and their biological mothers, recruited through multiple clinical sites. Diagnoses (via DSM-IV criteria) and onset dates of disorders were finalized "best estimate" psychiatrists, and based on multiple information sources. Mothers provided developmental data in a structured interview. Difficult temperament predicted earlier onset of MDD and first internalizing disorder, but its effect was ameliorated if the family was intact during early childhood. Further, the importance of difficult temperament decreased as a function of time. Perinatal problems and developmental delay did not impact onset ages of disorders, and none of the early childhood characteristics associated with MDD episode severity. Children with MDD may have added disadvantage of earlier onset if they had a difficult temperament in infancy. Because early temperament mirrors physiological reactivity and regulatory capacity, it can affect various areas of functioning related to psychopathology. Early caregiver stability may attenuate some adverse effects of difficult infant temperament.

    Full Text Available The turn of the nineteenth and twentieth century was witness to an unprecedented wave of emigration from East Central Europe, with an estimated 1-1.5 million people leaving for the United States from the territory of Hungary. Such loss of population, mostly young males in their prime, shocked the nation and served as a subject for discussion in various forms and on multiple levels of discourse, from the newspaper reports through literary depictions, to scholarly publications and conferences. In this paper I examine significant monographs as well as conference volumes and proceedings, analyzing the major opinions and debates surrounding the causes and consequences of the Great Transatlantic Emigration. I discuss the most significant publications that appeared before the coming of the First World War, which put an end to mass emigration from Europe. These works in a sense represented the best that Hungarian migration studies had to offer for more than half a century, which makes them particulary worthy of scholarly attention.

    Full Text Available The stress-induced epimutations could be inherited over generations and play important roles in plant adaption to stressful environments. Upland rice has been domesticated in water-limited environments for thousands of years and accumulated drought-induced epimutations of DNA methylation, making it epigenetically differentiated from lowland rice. To study the epigenetic differentiation between upland and lowland rice ecotypes on their drought-resistances, the epigenetic variation was investigated in 180 rice landraces under both normal and osmotic conditions via methylation-sensitive amplified polymorphism (MSAP technique. Great alterations (52.9~54.3% of total individual-locus combinations of DNA methylation are recorded when rice encountering the osmotic stress. Although the general level of epigenetic differentiation was very low, considerable level of ΦST (0.134~0.187 was detected on the highly divergent epiloci (HDE. The HDE detected in normal condition tended to stay at low levels in upland rice, particularly the ones de-methylated in responses to osmotic stress. Three out of four selected HDE genes differentially expressed between upland and lowland rice under normal or stressed conditions. Moreover, once a gene at HDE was up-/down-regulated in responses to the osmotic stress, its expression under the normal condition was higher/lower in upland rice. This result suggested expressions of genes at the HDE in upland rice might be more adaptive to the osmotic stress. The epigenetic divergence and its influence on the gene expression should contribute to the higher drought-resistance in upland rice as it is domesticated in the water-limited environment.

    2011-07-01

    Full Text Available In the current economic situation the former, intensive fertiliser recommendation system is unfit to help Hungarian farmers in their fertilising practice. The aim of the new system has been to apply the lowest possible NPK rates required to achieve safe and high yields as well as allowing minimal agricultural NP losses to surface and subsurface waters. The new system was developed by using the correlations revealed by analyzing the results of long-term fertilisation experiments set up in Hungary between 1960 and 2000. Several field experiments as well as comparative analyses confirmed the correctness of the basic principles as well as of the methods of calculating fertiliser rates of the new system. An estimated amount of 3,200,000 € was saved for the Hungarian farmers in 2007 alone by giving recommendations for more than 160,000 ha arable land applying the new system.

    Full Text Available This study uses Hungarian quarterly data from the International Monetary Fund to estimate a distributed lag model whose coefficients allow derivation of the short-run and long-run marginal propensities to consume.  MPCs are main factors determining the consumption, investment, government spending, and export and import multipliers of the economy.  Hungary's economy has stagnated and its policy makers are exploring new ways to manage its economy.  Our model reveals that the numerical value of Hungarian short-run marginal propensity to consume (MPC is 0.4081181655 and the long-run MPC is 0.9458619.  These results are consistent with the corresponding figures in emerging and advanced economies.  These derived MPCs suggest that Hungarian economic policy makers should use fiscal instruments to bring these macroeconomic variables back to their long-term trend effectively

    Full Text Available Abstract Background The cervical cancer screening program implemented in Hungary to date has not been successful. Along with screening, vaccination is an effective intervention to prevent cervical cancer. The aim of this study was to assess the cost-effectiveness of adding vaccination with the human papillomavirus 16/18 vaccine to the current cervical cancer screening program in Hungary. Methods We developed a cohort simulation state-transition Markov model to model the life course of 12-year-old girls. Eighty percent participation in the HPV vaccination program at 12 years of age was assumed. Transitional probabilities were estimated using data from the literature. Local data were used regarding screening participation rates, and the costs were estimated in US $. We applied the purchasing power parity exchange rate of 129 HUF/$ to the cost data. Only direct health care costs were considered. We used a 3.7% discount rate for both the cost and quality-adjusted life years (QALYs. The time horizon was 88 years. Results Inclusion of HPV vaccination at age 12 in the cervical cancer prevention program was predicted to be cost-effective. The incremental cost-effectiveness ratio (ICER of adding HPV vaccination to the current national cancer screening program was estimated to be 27 588 $/QALY. The results were sensitive to the price of the vaccine, the discount rate, the screening participation rate and whether herd immunity was taken into account. Conclusions Our modeling analysis showed that the vaccination of 12-year-old adolescent girls against cervical cancer with the AS04-adjuvanted human papillomavirus 16/18 vaccine would be a cost-effective strategy to prevent cervical cancer in Hungary.

  15. Seasonal evaluation of the land surface scheme HTESSEL against remote sensing derived energy fluxes of the Transdanubian region in Hungary

    E. L. Wipfler

    2011-04-01

    Full Text Available The skill of the land surface model HTESSEL is assessed to reproduce evaporation in response to land surface characteristics and atmospheric forcing, both being spatially variable. Evaporation estimates for the 2005 growing season are inferred from satellite observations of the Western part of Hungary and compared to model outcomes. Atmospheric forcings are obtained from a hindcast run with the Regional Climate Model RACMO2. Although HTESSEL slightly underpredicts the seasonal evaporative fraction as compared to satellite estimates, the mean, 10th and 90th percentile of this variable are of the same magnitude as the satellite observations. The initial water as stored in the soil and snow layer does not have a significant effect on the statistical properties of the evaporative fraction. However, the spatial distribution of the initial soil and snow water significantly affects the spatial distribution of the calculated evaporative fraction and the models ability to reproduce evaporation correctly in low precipitation areas in the considered region. HTESSEL performs weaker in dryer areas. In Western Hungary these areas are situated in the Danube valley, which is partly covered by irrigated cropland and which also may be affected by shallow groundwater. Incorporating (lateral groundwater flow and irrigation, processes that are not included now, may improve HTESSELs ability to predict evaporation correctly. Evaluation of the model skills using other test areas and larger evaluation periods is needed to confirm the results.

    Based on earlier sensitivity analysis, the effect of a number of modifications to HTESSEL has been assessed. A more physically based reduction function for dry soils has been introduced, the soil depth is made variable and the effect of swallow groundwater included. However, the combined modification does not lead to a significantly improved performance of HTESSEL.

    Full Text Available The emergence of a seemingly harmonic symbiosis between Hungarian majority and Jewish minority in 19th century Hungary was a unique phenomenon in a European country where the proportion of Jews was close to 5 percent of the total population, and about 20 percent of the capital city, Budapest. However, after the shocking experience of the persecution in 1944 it was to expect that the factor –unlimited readiness for assimilation in the belief of the unlimited readiness of the majority for accepting it- that made the uniqueness of the Hungarian Jewry will cease to exist. Since quite a large group of the Hungarian Jews survived the Shoah it was not purely a theoretical question that what sort of identity strategies would emerge among the Jewish population of the country. How did the Jews react to the dramatic political changes that occurred in the decades following the Shoah, what kind of identity strategies they developed in the search for their place in the post-war Hungarian society? After a historical introduction the article discusses the changing socio-demographic and socio-economic characteristics of the post-war Hungarian Jews, Jewish politics in the decades of communist rule and finally the identity problems emerged in the post-war decades.

  17. The Beginning of Variable star astronomy in Hungary

    Science.gov (United States)

    Zsoldos, Endre

    Variable star astronomy began in Hungary as elsewhere: new objects have been recognized in the sky. Comets appeared in 16th - 17th century chronicles. The first mention of the new star of 1572 seems to be the "Prognosticon" of Wilhelm Misocacus, printed in 1578. New stars were discussed in the 17th century by Jesuits as well as Protestants. The work of Jacob Schnitzler is especially interesting from this point. The Cartesians dealt with new stars with less enthusiasm, they hardly mentioned them. The beginning of the 19th century saw the development of science in Hungarian, variable stars, however, were left out. The birth of variable star astronomy might be linked to the Ógyalla Observatory, originally a private observatory of Miklós Konkoly Thege. The 1885 supernova in the Andromeda Nebula were observed there, as well as the spectra of a few interesting variable stars. Theoretical astrophysics also has its beginnings in Ógyalla through the work of Radó Kövesligethy. Professional variable star astronomy started here in the early 20th century through the work of Antal Tass

  18. Structural Components of Lifestyle and Beyond: The Case of Hungary

    Directory of Open Access Journals (Sweden)

    Tamás Keller

    2011-06-01

    Full Text Available This paper deals with the question of when and how lifestyle and its components are important in social stratification. There is considerable consensus among scholars about the structure of the society being a consequence of hierarchical dimensions like occupation, income, or wealth. Some thirty years ago, largely based on Bourdieu’s “Distinction”, a new paradigm emerged highlighting the lifestyle components and the value-oriented cultural and material consumption in stratifi cation. The idea refl ects the empirical fi nding that inequality between social classes has largely decreased, giving priority to horizontal lifestyle differentiation instead of vertical inequality dimensions. From a theoretical viewpoint, a challenge in the approach is finding out to what extent lifestyle typology is of a non-vertical character in reality. This social determination of lifestyle is investigated for Hungary when comparing an occupation-based typology with a consumption-based one. On the one hand, results reveal that the effects of structural components on social status are stronger than those of lifestyle. On the other hand, lifestyle turns out to be less independent of social position and the top and bottom levels of the lifestyle typology are particularly predictable by structural measures.

  19. Spent fuel management in Hungary: Current status and prospects

    1996-01-01

    The Paks Nuclear Power Plant Ltd. operates the only NPP of Hungary, consisting of a 4 WWER-440 type units. Since 1989, approximately 40-50 % of the total yearly electricity generation of the country has been supplied by this plant. The fresh fuel is imported from Russia (previously from the Soviet Union) and the spent fuel assemblies are shipped back to Russia for later reprocessing after 5 years of decay storage in the spent fuel pools of the plant. Seeing the political and economical changes that started in Russia, the Paks NPP's management made a decision in 1990 to study the implementation of an independent spent fuel storage facility (ISFSF) at the Paks site and in 1992 to choose the GEC-ALSTHOM's MVDS. On the basis of the Construction License issued by the HAEC, the construction of the ISFSF was started in March 1995. The paper gives general information on the spent fuel arisings, the storage at the site, the shipment to Russia and on the implementation of the ISFSF. (author). 3 refs

    Full Text Available Introduction. Diabetic retinopathy (DR is a sight-threatening complication of diabetes. Telemedicine tools can prevent blindness. We aimed to investigate the patients’ satisfaction when using such tools (fundus camera examination and the effect of demographic and socioeconomic factors on participation in screening. Methods. Pilot study involving fundus camera screening and self-administered questionnaire on participants’ experience during fundus examination (comfort, reliability, and future interest in participation, as well as demographic and socioeconomic factors was performed on 89 patients with known diabetes in Csongrád County, a southeastern region of Hungary. Results. Thirty percent of the patients had never participated in any ophthalmological screening, while 25.7% had DR of some grade based upon a standard fundus camera examination and UK-based DR grading protocol (Spectra™ software. Large majority of the patients were satisfied with the screening and found it reliable and acceptable to undertake examination under pupil dilation; 67.3% were willing to undergo nonmydriatic fundus camera examination again. There was a statistically significant relationship between economic activity, education and marital status, and future interest in participation. Discussion. Participants found digital retinal screening to be reliable and satisfactory. Telemedicine can be a strong tool, supporting eye care professionals and allowing for faster and more comfortable DR screening.

    A cross-sectional survey was conducted in Hungary using the Cerberus system which includes: 1) a questionnaire addressing the risk factors for stroke/cardiovascular disease; 2) amplifiers to record the pulse waves of cerebral arteries (rheoencephalography) and peripheral arteries, electrocardiogram and electroencephalogram. Additionally, subjects were measured for carotid stenosis by Doppler ultrasound and 12-lead electrocardiogram; subjects were also screened for blood cholesterol, glucose, and triglyceride levels. Prevalence of the following stroke risk factors was identified: overweight, 63.25%; sclerotic brain arteries (by rheoencephalogram), 54.29%; heart disease, 37.92%; pathologic carotid flow, 34.24%; smoking, 30.55%; high blood cholesterol, 28.70%; hypertension, 27.83%; high triglyceride, 24.35%; abnormality in electrocardiogram, 20%; high glucose, 15.95%; symptoms of transient ischemic attack, 16.07%; alcohol abuse, 6.74%; and diabetes, 4.53%. The study demonstrates a possible model for primary cardiovascular disease/stroke prevention. This method offers a standardizable, cost effective, practical technique for mass screenings by identifying the population at high risk for cardiovascular disturbances, especially cerebrovascular disease (primary prevention). In this model, the rheoencephalogram can detect cerebrovascular arteriosclerosis in the susceptibility/presymptomatic phase, earlier than the Doppler ultrasound technique. The method also provides a model for storing analog physiological signals in a computer-based medical record and is a first step in applying an expert system to stroke prevention.

    In recent years, Ehrlichia canis and Hepatozoon canis transmitted by Rhipicephalus sanguineus were reported from Hungary. The aim of the present study was to reveal the spatial distribution pattern of pathogens transmitted by R. sanguineus in a sentinel species, red fox (Vulpes vulpes) in Hungary and to analyse the relationship of these patterns with landscape and climate by geographical information systems. Fox carcasses, representing 0.5% of the total fox population were randomly selected out of all the foxes of Hungary. The spleen samples of the animals were tested by real-time PCR for Anaplasma platys, Babesia vogeli, E. canis and H. canis infection. Positive results were confirmed by conventional PCR followed by sequencing. The prevalence of H. canis infection was 22.2% (95% CI=18.4-26.4%), and this parasite was detected in all areas including the mountain regions of Hungary. These findings indicate that other tick species or other transmission routes (oral and transplacental) might be in the background of the countrywide distribution of H. canis. Anaplasma platys was not found; nevertheless, the prevalence of Anaplasma phagocytophilum infection transmitted by Ixodes ricinus was 12.5% (95% CI=9.7-16.1%) in foxes. B. vogeli and E. canis infection was not detected. There was no correlation between environmental parameter values in the home range of foxes and A. phagocytophilum or H. canis infection, which is in line with that observed in the case of tick species infesting foxes in Hungary. The results of this study indicate that R. sanguineus, if present, might be rare in Hungary. Our baseline study can be used for future evaluation of the effect of climate change on the spreading and emergence of R. sanguineus transmitted pathogens in Hungary. Copyright © 2015 Elsevier GmbH.

    Water stress susceptibility index (WSSI) and stomatal conductance were used to determine the stress tolerance of 10 upland cotton cultivars during 2009 at Sindh Agriculture University, Tandojam, Pakistan. The experiment was conducted in spilt plot design with irrigations as main plots and cultivars as sub-plots. Two irrigation treatments were used i.e. one has two irrigations (water stress) and other has eight irrigations (non-stress). Analysis of variance revealed significant genotypic differences about WSSI for all the traits. Non-significant interaction between irrigations and cultivars for seed cotton yield and boll weight exhibited varietals stability over irrigation regimes, whereas significant interactions between above parameters for plant height and bolls per plant suggested genotypic instability over irrigation treatments for these traits. Overall, cultivars mean performance for all the traits in stress conditions was poor as compared to non-stress conditions, nevertheless some cultivars exhibited nonsignificant mean differences in both irrigation regimes, thus showing higher stress tolerance. The WSSI values of seed cotton yield as displayed in bi plot revealed that cultivars CRIS-477, CRIS-483 and CRIS-486 were found highly susceptible to water stress. Cultivars CRIS-476, CRIS-482, CRIS-487 and NIAB-78 were characterized as highly susceptible with minimum production even under optimum irrigation conditions. Cultivar CRIS-9 was moderately tolerant as produced low production. However, cultivars CRIS-485 and CRIS-484 were found highly stress tolerant because of minimum WSSI value and lower stomatal conductance. Negative correlations between water stress and WSSI for seed cotton yield and plant height revealed that any increase in the degree of stress caused a corresponding decrease in WSSI. (author)

  4. Storage filters upland suspended sediment signals delivered from watersheds

    Climate change, tectonics, and humans create long- and short-term temporal variations in the supply of suspended sediment to rivers. These signals, generated in upland erosional areas, are filtered by alluvial storage before reaching the basin outlet. We quantified this filter using a random walk model driven by sediment budget data, a power-law distributed probability density function (PDF) to determine how long sediment remains stored, and a constant downstream drift velocity during transport of 157 km/yr. For 25 km of transport, few particles are stored, and the median travel time is 0.2 yr. For 1000 km of transport, nearly all particles are stored, and the median travel time is 2.5 m.y. Both travel-time distributions are power laws. The 1000 km travel-time distribution was then used to filter sinusoidal input signals with periods of 10 yr and 104 yr. The 10 yr signal is delayed by 12.5 times its input period, damped by a factor of 380, and is output as a power law. The 104 yr signal is delayed by 0.15 times its input period, damped by a factor of 3, and the output signal retains its sinusoidal input form (but with a power-law “tail”). Delivery time scales for these two signals are controlled by storage; in-channel transport time is insignificant, and low-frequency signals are transmitted with greater fidelity than high-frequency signals. These signal modifications are essential to consider when evaluating watershed restoration schemes designed to control sediment loading, and where source-area geomorphic processes are inferred from the geologic record.

    Full Text Available Rice cooking quality is usually evaluated by texture and stickiness characteristics using many different methods. Gelatinization temperature, amylose content, viscosity (Brookfield viscometer and Rapid Visco Analyzer, and sensory analysis were performed to characterize culinary quality of rice grains produced under two cropping systems and submitted to different technologies. All samples from the upland cropping system and two from the irrigated cropping system presented intermediate amylose content. Regarding stickiness, BRS Primavera, BRS Sertaneja, and BRS Tropical showed loose cooked grains. Irrigated cultivars presented less viscosity and were softer than upland cultivars. Upland grain samples had similar profile on the viscoamylografic curve, but the highest viscosity peaks were observed for BRS Alvorada, IRGA 417, and SCS BRS Piracema among the irrigated cropping system samples. In general, distinct grain characteristics were observed between upland and irrigated samples by cluster analysis. The majority of the upland cultivars showed soft and loose grains with adequate cooking quality confirmed by sensory tests. Most of the irrigated cultivars, however, presented soft and sticky grains. Different methodologies allowed to improve the construction of the culinary profile of the varieties studied.

    In recent years, the significant improvement in point source depuration technologies has highlighted problems regarding, in particular, phosphorus and nitrogen pollution of surface and groundwater caused by agricultural non-point (diffuse) sources (NPS). Therefore, there is an urgent need to determine the relationship between agriculture and chemical and ecological water quality. This is a worldwide problem, but it is particularly relevant in countries, such as Hungary, that have recently become members of the European Community. The Italian Foreign Ministry has financed the PECO (Eastern Europe Countries Project) projects, amongst which is the project that led to the present paper, aimed at agricultural sustainability in Hungary, from the point of view of NPS. Specifically, the aim of the present work has been to study nitrates in Hungary's main aquifer. This study compares a model showing aquifer intrinsic vulnerability to pollution (using the DRASTIC parameter method; Aller et al. [Aller, L., Truman, B., Leher, J.H., Petty, R.J., 1986. DRASTIC: A Standardized System for Evaluating Ground Water Pollution Potential Using Hydrogeologic Settings. US NTIS, Springfield, VA.]) with a field-scale model (GLEAMS; Knisel [Knisel, W.G. (Ed.), 1993. GLEAMS--Groudwater Leaching Effects of Agricultural Management Systems, Version 3.10. University of Georgia, Coastal Plain Experimental Station, Tifton, GA.]) developed to evaluate the effects of agricultural management systems within and through the plant root zone. Specifically, GLEAMS calculates nitrate nitrogen lost by runoff, sediment and leachate. Groundwater monitoring probes were constructed for the project to measure: (i) nitrate content in monitored wells; (ii) tritium (3H) hydrogen radioisotope, as a tool to estimate the recharge conditions of the shallow groundwater; (iii) nitrogen isotope ratio delta15N, since nitrogen of organic and inorganic origin can easily be distinguished. The results obtained are satisfactory

    Although arsenic contamination in the three countries described herein differs, a number of common themes emerge. In each country, the presence of arsenic is both long term and of geological origin. Moreover, in each of these countries, arsenic was only recently discovered to be a potential public health problem, having been first formally recognized in the 1980s or 1990s. In Bangledesh, exposure of the public to arsenic arose as a result of the search for microbially safe drinking water; this search resulted in the sinking of tube wells into aquifers. In Hungary, the natural bedrock geology was responsible for contamination of aquifer water. The genesis of arsenic contamination in Thailand arose primarily from small-scale alluvial mining activities, which mobilized geologically bound arsenic. Because of the complex chemistry of arsenic, and variability in where it is found and how it is bound, multiple mitigation methods must be considered for mitigating episodes of environmental contamination. The Ron Phibun region of Thailand has a 100-yr history of tin mining. A geological survey of the region was conducted in the mid-1990s by the Department of Mineral Resources and Department of Industry of Thailand, and was supported by the British Geological Society. Skin cancer in Thailand was first reported in 1987, in the southern part of the country; among other symptoms observed, there was evidence of IQ diminutions among the population. Arsenic water levels to 9,000 pg/L were reported; such levels are substantially above any guideline levels. A long-term plan to mitigate arsenic contamination was devised in 1998-2000. The plan involved removal of arsenic-contaminated land and improved management of mining wastes. However, at $22 million, the cost was deemed prohibitive for the regional Thai economy. An alternative solution of providing pipeline drinking water to the exposed population was also unsuccessful, either because arsenic contamination levels did not fall

  8. Budapest, Hungary, Perspective View, SRTM Elevation Model with Landsat Overlay

    2004-01-01

    After draining the northern flank of the Alps Mountains in Germany and Austria, the Danube River flows east as it enters this west-looking scene (upper right) and forms the border between Slovakia and Hungary. The river then leaves the border as it enters Hungary and transects the Transdanubian Mountains, which trend southwest to northeast. Upon exiting the mountains, the river turns southward, flowing past Budapest (purplish blue area) and along the western margin of the Great Hungarian Plain.South and west of the Danube, the Transdanubian Mountains have at most only about 400 meters (about 1300 feet) of relief but they exhibit varied landforms, which include volcanic, tectonic, fluvial (river), and eolian (wind) features. A thick deposit of loess (dust deposits likely blown from ancient glacial outwash) covers much of this area, and winds from the northwest, funneled between the Alps and the Carpathian Mountains, are apparently responsible for a radial pattern of erosional streaks across the entire region.This image was generated from a Landsat satellite image draped over an elevation model produced by the Shuttle Radar Topography Mission (SRTM). The view uses a 3-times vertical exaggeration to enhance topographic expression. The false colors of the scene result from displaying Landsat bands 1, 4, and 7 in blue, green, and red, respectively. Band 1 is visible blue light, but bands 4 and 7 are reflected infrared light. This band combination maximizes color contrasts between the major land cover types, namely vegetation (green), bare ground (red), and water (blue). Shading of the elevation model was used to further highlight the topographic features.Elevation data used in this image was acquired by the Shuttle Radar Topography Mission (SRTM) aboard the Space Shuttle Endeavour, launched on February 11, 2000. SRTM used the same radar instrument that comprised the Spaceborne Imaging Radar-C/X-Band Synthetic Aperture Radar (SIR-C/X-SAR) that flew twice on the Space

    Hungary is a small country in the middle of Europe with a population of 10 million. Many religions are represented in the country but the majority of the population is Christian. The Hungarian medical education and practice based on the 'German School' and the modem medicine has been started more than 200 years ago. At the same time some of the medical school have been established first in Nagyszombat and the school for surgery in Kolozsyar, later in Debrecen 80 years ago. Recently we have four medical faculties. From the beginning of implementation of modern medicine many efforts were taken to establish the relevant legal frame and ethical rules to help and make understandable and acceptable for the society of various medical interventions. The previous mentioned structure was before and presently conformed with the political and social structure of the country. The initial of tissue for transplantation in medicine was widely accepted by medical fraternity since the middle of the century. Recently tissue grafts are performed daily is in burn, reconstructive surgery, in bone and nerve surgery, unfortunately we use commercial products in heart surgery. At the initial phase of our tissue banking activity, we first followed the American Association Tissue Banking procedures based on our personal contact with leading US Tissue Bank and the American Association of Tissue Banks. Later after joining the Europe Association of Tissue Bank we played an active role in the establishing of the Europe recommendations related to legal, ethical and technical rules of tissue banking. In this presentation the legal frame and the recent ethical concept for tissue donation as well as the technical possibilities and the donor recreation programme of tissue banks will be introduced to the audience. Also the problems of legal harmonization will be mentioned to which we are facing as an associated country to the European Union

    In 2012, smoking restrictions were extended to hospitality venues in Hungary. Women working in bars and restaurants were primarily affected by the intervention. In this research, we analyze the effect of this smoking ban on the outcomes of their pregnancies. Using individual live birth, fetal loss, and infant mortality registry data, we examine the probability of live birth, indicators of health at birth, and the probability of death in the first year of life. We apply a difference-in-differences framework and show that the smoking ban has improved health at birth. We observed birth weight to increase by 56 g (95% CI: 4.2 to 106.8) and gestation length by 0.19 weeks (95% CI: 0.02 to 0.36). Due to the ban, the probability of being born with very low and low birth weight has decreased by 1.2 and 2.2 percentage points, respectively (95% CI: -0.2 to -2.2 and 0.06 to -4.4), and we see a 0.9 percentage points reduction in the chance of being born very preterm (95% CI: -0.03 to -1.9). We also observe a decrease in the probability of being born with a low Ponderal index (decrease of 4.1 percentage points, 95% CI: -0.7 to -7.5). Performing a series of robustness and placebo tests, we provide evidence that supports the causal interpretation of our results. We also show that the ban was more beneficial for newborns of parents with low educational attainment and at the bottom of the fetal health endowment distribution. Copyright © 2018 Elsevier B.V.

  11. Basic education in communist Hungary. A commons approach

    Directory of Open Access Journals (Sweden)

    Ferenc Gyuris

    2014-08-01

    Full Text Available In commons research, the study of the ‘knowledge commons’ has emerged as a new field of interest over the last few years. Our paper begins by providing a brief overview of the state of research in the field, and proceeds by discussing some crucial but relatively underconceptualised issues. The difference between information and knowledge, and the ambiguities surrounding the claim that all sorts of knowledge can be considered part of the commons, are the focal point here. We also pay close attention to education, arguing that it is not a common good, but rather a common-pool resource institution that ensures that some forms of knowledge can be governed as a commons. With regard to these issues, the article provides a case study, one in which we analyse basic education in Communist Hungary, and look for evidence of the commons design principles as outlined in Elinor Ostrom’s IAD Framework. Given the complex nature of basic education, we investigate it from three points of view: as a service, as a set of physical structures (e.g. school buildings, and as a complex of organizational structures (e.g. legal and financial arrangements. On the basis of empirical findings we argue that basic education in the Stalinist epoch did not correspond to Ostromian design principles. Basic education, therefore, was not managed in an equitable way, and its geographical accessibility was uneven. During the ‘technocratic’ Communism of the 1960s, 1970s, and 1980s, the education system underwent important changes. However, though the circle of those who had some impact on the governance of education expanded, most individuals involved with the education system were still excluded. As a result, the commons approach did not become stronger in general, nor did spatial unevenness with respect to access to basic education decrease. The paper finishes with a brief conclusion of our findings and a discussion of some questions for future research.

    In Hungary, radiation protection training for radiation workers has been introduced in very early, just following the publication of the ICRP recommendation No. 26. Before that, in some of the institutions, radiation protection training was recommended for technicians and medical doctors working in nuclear medicine, X-ray diagnostic radiology and radiation therapy, as well as in some of industrial applications, but not on regular way. Since 1988, radiation protection training regulated by the Ministry of Health and required for all of the workers in radiation workplaces licensed by the authority the State Public Health and Medical Officers Service (SPHAMOS). Decree No. 16/2000. (VI. 8.) EuM of the Minister of Health on the enforcement of Clauses of the Nuclear Law 116/1996 regulates the radiation protection training of Radiation Workers (RW). Annex 4 of Decree sees radiation protection training and in-service training: Persons performing conducted work in the field of the use of the nuclear energy and any other work within legal relationship shall be educated in training and in-service training at an interval of 5 years. Three levels of the training introduced; basic, extended and comprehensive, based on radiation risk related to the given job. Several institutions are involved in performing radiation protection training, such universities, scientific institutions, Regional Radiological Health Centers (RRHC) of SPHAMOS, private enterprises etc. All training course material is subject to accreditation. Most of the faculties of the universities involved in training of natural sciences and engineering provide subjects on the fundamentals of dosimetry, radiobiology and radiation protection within the courses of physics, biophysics, chemistry, biology, ecology etc. These courses take 5-10 contact hours per week on average. The members of the Hungarian Committee of EUTERP Platform summarize their broad experience collected in the past 20 year. (author)

  14. Impacts of prescribed fire on Pinus rigida Mill. in upland forests of the Atlantic Coastal Plain.

    A comparative analysis of the impacts of prescribed fire on three upland forest stands in the Northeastern Atlantic Plain, NJ, USA, was conducted. Effects of prescribed fire on water use and gas exchange of overstory pines were estimated via sap-flux rates and photosynthetic measurements on Pinus rigida Mill. Each study site had two sap-flux plots, one experiencing prescribed fire and one control (unburned) plot for comparison before and after the fire. We found that photosynthetic capacity in terms of Rubisco-limited carboxylation rate and intrinsic water-use efficiency was unaffected, while light compensation point and dark respiration rate were significantly lower in the burned vs control plots post-fire. Furthermore, quantum yield in pines in the pine-dominated stands was less affected than pines in the mixed oak/pine stand, as there was an increase in quantum yield in the oak/pine stand post-fire compared with the control (unburned) plot. We attribute this to an effect of forest type but not fire per se. Average daily sap-flux rates of the pine trees increased compared with control (unburned) plots in pine-dominated stands and decreased in the oak/pine stand compared with control (unburned) plots, potentially due to differences in fuel consumption and pre-fire sap-flux rates. Finally, when reference canopy stomatal conductance was analyzed, pines in the pine-dominated stands were more sensitive to changes in vapor pressure deficit (VPD), while stomatal responses of pines in the oak/pine stand were less affected by VPD. Therefore, prescribed fire affects physiological functioning and water use of pines, but the effects may be modulated by forest stand type and fuel consumption pattern, which suggests that these factors may need to be taken into account for forest management in fire-dominated systems. © The Author 2016.

    2013-01-01

    The Cairngorm massif in NE Scotland (Figure 1) is an excellent example of a preglacial upland landscape formed in granite. Glacial erosion in the mountains has been largely confined to valleys and corries (Rea, 1998) and so has acted to dissect a pre-existing upland (Figure 2). Intervening areas of the massif experienced negligible glacial erosion due to protective covers of cold-based ice (Sugden, 1968) and preserve a wide range of pre-glacial and non-glacial landforms and reg...

    1989-01-01

    The nuclear accident at Chernobyl in April 1986 resulted in a significant increase in the inventory of radiocaesium retained in the soil in many regions of the United Kingdom. The deposition of 134 Cs provides a convenient tool for the examination of erosional processes in upland systems. Detailed soil sampling has been undertaken within the Plynlimon experimental catchments to establish the pattern of deposition of Chernobyl-derived radionuclides. The preliminary results of a combined radiometric and mineral magnetic approach to the study of the transport of Chernobyl-labelled sediments and their source areas on these upland catchments in mid-Wales are described.

    1997-01-01

    Full Text Available As identified by the detailed long-term monitoring networks at Plynlimon, increased sediment supply to upland fluvial systems is often associated with forestry land-use and practice. Literature is reviewed, in the light of recent results from Plynlimon sediment studies, to enable identification of the potential ecological impacts of fluvial particulate inputs to upland gravel bed rivers draining forested catchments similar to the headwaters of the River Severn. Both sediment transport and deposition can have significant impacts upon aquatic vertebrates, invertebrates and plants.

    2009-01-01

    Full Text Available Corporate governance ensures that boards are able to exercise appropriate scrutiny over management and that shareholders, as owners of the company, are able to hold boards accountable. As such, a high level of corporate governance contributes significantly to investors' confidence and market stability, thus fostering business efficiency. In 2005 the European Commission launched a recommendation on the boards of listed companies and invited Member States to follow the guidelines. In 2008 both Romania and Hungary launched a new Code of Corporate Governance on the basis of the EU recommendations. In my paper I present the EU principles, and by examining the national codes of Romania and Hungary I analyze to which extent and in what issues these two countries have adopted the EU recommendations. I concluded that by the new codes of corporate governance issued in 2008 Romania and Hungary have followed to a large extent the provisions of the EU recommendation.

    2014-11-01

    Full Text Available Background The importance of cross-border healthcare, medical and health tourism plays a significant role in the European health policy and health management. After dentistry, orthopaedic treatments are the leading motivation for seeking care in Hungary, as patients with rheumatic and motion diseases are drawn to the thermal spas and well-established orthopaedic centres. This paper aims to gain insight into foreign patients’ perspectives on their experience of having sought medical tourism in orthopaedic care in Hungary. Methods A patient survey was conducted in 2012 on motivations for seeking treatment abroad, orthopaedic care received and overall satisfaction. In addition, health professionals’ interviews, and 17 phone interviews were conducted in 2013 with Romanian patients who had orthopaedic treatment in Hungary. Finally, medical records of foreign patients were analysed. Results The survey was completed by 115 participants – 61.1% females, mean age= 41.9, 87% Romanian origin. Most of the patients came to Hungary for orthopaedic surgeries, e.g. arthroscopy, knee/hip prosthesis or spinal surgery. 72.6% chose Hungary because of related to perceived better quality and longstanding culture of Hungarian orthopaedic care. Over 57% of patients reported being ‘very satisfied’ with care received and 41.6% ‘satisfied’. The follow-up interviews further reflected this level of satisfaction, therefore many respondents stating they have already recommended the Hungarian healthcare to others. Conclusion Based on the findings, patients from neighbouring regions are increasingly seeking orthopaedic care in Hungary. Patients having orthopaedic care are highly satisfied with the quality of care, the whole treatment process from the availability of information to discharge summaries and would consider returning for further treatments.

    Farkas, Orsolya; Rákai, Anikó; Czáder, Károly; Török, Ákos

    2013-04-01

    The present paper focuses on the modelling of pollutant distribution and dispersion in an urban region that is located in a moderately industrialized town of Hungary, Székesfehérvár, with a population of 100,000. The study area is located close to the city centre, with different housing styles and different building elevations. High-rise buildings with 10 floors to small houses with gardens are found in the modelled area. The roundabout has 5 access roads; three major ones and two minor ones with different geometries and traffic load. The traffic load of the roads was defined by traffic count, while for the meteorological characteristics wind-statistics were created. Additional input parameters were the ground plan and the elevation of buildings. To simulate the airflow and the dispersion of pollutants a Computational Fluid Dynamics code called MISKAM was used. The background concentration was taken from the dataset of a nearby air quality monitoring station. According to vehicle counting the 5 roads of the roundabout have very different loads from 12 vehicles to more than 412 vehicles/hour. Three different grid systems were applied ranging from half million to 5 million cells. The difference in the results related to grid density was also evaluated. Wind speed distribution, wind turbulence and building wake flow patterns were identified by using the model. With the help of the simulation the NOx flow and dispersion of pollutants around the roundabout can be estimated and the critical locations with higher pollution concentration are presented. The results of the modelling can be more generalized and used in the design of the layout, development, traffic-control and environmental aspects of roundabouts located in small urban areas.

    Hydropower in boreal conditions is generally considered the energy source emitting the least greenhouse gas per kilowatt-hour during its life cycle. The purpose of this study was to assess the relative contribution of the land-use change on the modification of the carbon sinks and sources following the flooding of upland forested territories to create the Eastmain-1 hydroelectric reservoir in Quebec's boreal forest using Carbon Budget Model of the Canadian Forest Sector. Results suggest a carbon sink loss after 100 yr of 300,000 ± 100,000 Mg CO equivalents (COe). A wildfire sensitivity analysis revealed that the ecosystem would have acted as a carbon sink as long as carbon flux estimate resulted in emissions of 4 ± 2 g COe kWh as a contribution to the carbon footprint calculation, one-eighth what was obtained in a recent study that used less precise and less sensitive estimates. Consequently, this study significantly reduces the reported net carbon footprint of this reservoir and reveals how negligible the relative contribution of the land-use change in upland forests to the total net carbon footprint of a hydroelectric reservoir in the boreal zone can be.

    2013-01-01

    Since 1976 the spent and disused radioactive sources arisen in Hungary are stored in a central storage facility called Radioactive Waste Treatment and Disposal Facility operated by Public Limited Company for Radioactive Waste Management. The Facility is responsible for the record keeping, the waste acceptance procedure, the shipment and the storage or disposal (whether a certain source meets the waste acceptance criteria for disposal or not) of sources. Based on the more than 35 year old operation of the facility many experiences have been gathered regarding the technology for long-term storage of sources, the attitude of the users of sources, the evolution of the legislation and the national record keeping system. Recently a new legislation for the security of radioactive materials (including sources) was introduced, first in Central-Europe. It requires special security arrangements from the facility for transport and for storage. Due to the ongoing retrieval of radioactive waste formerly disposed of, partly containing sealed sources, there is a new challenge in the physical inventory control of historical waste. The paper would show the effect of the changes in the legislation system of record keeping or security on the users' attitude for discard of sources and on the management of the sources in the facility. The facility has a unique storage technology (shallow boreholes) in the narrow region. The sealed sources are placed into vertical pipes sunk into the surface. In the beginning, each of the sources were dropped into the pipe directly, recently they are placed in a metal tube first ensuring the retrieval. The lessons learned will be presented. There were several issues to introduce the new security arrangements (partly financially supported by US DOE) for storage and for transportation of sealed sources. These issues are addressed. In the past part of the sealed sources were disposed together with solid radioactive waste packaged in plastic bags. A waste

    In the frame of a co-operation agreement between Austrian Research Center Seibersdorf, Italian ENEA Institute for Radiation Protection and Hungarian KFKI Atomic Energy Research Centre, an intercomparison on WBC measurements using a modular bottle phantom was performed during 1995 in Hungary, on May-July 1996 in the Northern part of Italy. Results related to the relative bias for the three body masses are reported, together with indication of their compliance with ANSI report N13.30. It turned out that majority of the results were found to be within the performance criteria of the ANSI report, however there were also few outfalling results which were a good indication to check and improve the reliability of calibration and/or other methodological procedures. In the contrary of the expectance, the results related to 20 kg phantom resulted not significantly worse than those obtained for the adult phantom indicating the capacity for the participating WBC centres of measuring people from the general population. [Italiano] Nell`ambito di un accordo di collaborazione tra il Centro di Ricerca di Seibersdorf (Austria), l`Istituto per la Radioprotezione dell`ENEA (ENEA AMB PRO IRP) ed il Centro di Ricerca per l`Energia Atomica KFKI di Budapest (Ungheria), si e` svolto un interconfronto su misure WBC basato sull`utilizzo di un unico fantoccio modulare a bottiglie cui hanno partecipato centri WBC Ungheresi (1995) ed Italiani (Maggio-Giugno 1996). Nel presente rapporto tecnico vengono presentati i risultati ottenuti ed una loro analisi impostata sui criteri di valutazione recentemente proposti dall`ANSI nel rapporto N. 13.30. Sulla base di tale criterio la maggior parte dei risultati dell`interconfronto rientra nell`intervallo di accettabilita`; nei pochi casi di non accettabilita` si rende invece necessaria una revisione dei dati di calibrazione e delle metodologie. Contrariamente a quanto si poteva prevedere, i risultati relativi al fantoccio da 20 kg appaiono sostanzialmente

  5. The Major Trends of Food Consumption in Hungary

    2016-12-01

    Full Text Available In the beginning of the 20th century the food consumption levels were much lower than later in the century, when food production increased as well. The selection of foodstuffs became wider and we can observe the modernisation of nutrition principles too, which both had a positive impact on consumption. The variety of food was also affected by the increasing life expectancy. The emergence of more modern ways in food consumption is halted not only by the traditions but by the fact that healthier foods are more expensive than fat or cereal prices. There is a significant correlation between the income levels and the quality of consumed food, as it can be observed that in different regions in Hungary. My aim was also to investigate the change in consumer behaviour in parallel with the increase of income levels; to see which sort of foods are preferred by the wealthier, and which are preferred by the ones with less income. It is also important to analyse the economic and social indicators on regional and other spatial levels and to compare them with food consumption. The annual net income per capita is usually higher in more developed regions than in the less developed ones. Therefore, the expenditure spent on better quality and more expensive food products is also higher. Similarly, in the case of the population there are differences in consumer habits according to purchasing power. For instance, for people with higher income one of the most important factors is to buy healthy and high quality food, but for the ones with lower income it can be a struggle only to find food in sufficient quantities, and quality cannot be as much of an issue. In the consumer basket, foodstuff accounts for approximately one-third of the overall expenditure. In this study I analysed the annual expenditure of Hungary’s population on foodstuffs and the annual quantity of food consumed by households per capita on a regional level between 2010 and 2013.

The paper would show the effect of the changes in the legislation system of record keeping or security on the users' attitude for discard of sources and on the management of the sources in the facility. The facility has a unique storage technology (shallow boreholes) in the narrow region. The sealed sources are placed into vertical pipes sunk into the surface. In the beginning, each of the sources were dropped into the pipe directly, recently they are placed in a metal tube first ensuring the retrieval. The lessons learned will be presented. There were several issues to introduce the new security arrangements (partly financially supported by US DOE) for storage and for transportation of sealed sources. These issues are addressed. In the past part of the sealed sources were disposed together with solid radioactive waste packaged in plastic bags. A

  7. Heavy metals in garden soils along roads in Szeged, Hungary

    The soils of the urban environment, owing to the various anthropogenic activities, can be contaminated by heavy metals. The traffic is well-known for more decades to be main source of heavy metals mostly in cities. The accumulation of these elements can have different effects, either directly endangering the natural soil functions, or indirectly endangering the biosphere by bio-accumulation and inclusion in the food chain. The hobby gardens and the vegetable gardens directly along roads can be potential risky for people since unknown amount of heavy metals can be accumulated into organization of local residents due to consumption of vegetables and fruits grown in their own garden. The aim of this study was to determine the heavy metal content of garden soils directly along roads with heavy traffic in order to assess possible risk for human health. The total content and the mobile content of Cd, Co, Cr, Cu, Ni, Pb and Zn have been determined in samples from garden soils along 5 busy roads of Szeged, South Hungary. Enrichment factor has been calculated with the help of control soil samples far from roads. The soil properties basically influencing on metal mobility have also been examined. Finally, the human health risk of these garden soils has been modelled by determination of health risk quotient (HRQ). As a result of our investigations, it can be claimed that mostly Cu, Zn and to a lesser degree the Ni, Cr and Pb accumulated in garden soils along roads depending on the traffic density. In general, the topsoils (0-10 cm) had higher amount of these metals rather than the subsoils (40-50 cm). Ni of these metals has approached; Cu has exceeded limit value while Pb is under it. Cd is very high in both soils along roads and control ones far from roads. Garden soils along the roads have such basic soil parameters (pH, mechanical soil type, humus content) that prove fairly high metal-binding capacity for these soils. Total risk of usage of these gardens (ingestion of soil

    Since 1996, the emergence of Asian-origin highly pathogenic avian influenza subtype H5N1 has spurred great concern for the global poultry industry. In the United States, there is concern over the potential of a foreign avian disease incursion into the country. Noncommercial poultry operations, such as upland game bird facilities in the United States, may serve as a potential source of avian disease introduction to other bird populations including the commercial poultry industry, backyard flocks, or wildlife. In order to evaluate how to prevent disease transmission from these facilities to other populations, we examined biosecurity practices and bird movement within the upland game bird industry in the United States. Persons that held a current permit to keep, breed, or release upland game birds were surveyed for information on biosecurity practices, flock and release environments, and bird movement parameters. Biosecurity practices vary greatly among permit holders. Many facilities allow for interaction between wild birds and pen-reared birds, and there is regular long-distance movement of live adult birds among facilities. Results suggest that upland game bird facilities should be targeted for biosecurity education and disease surveillance efforts.

    Graphical abstract: Elevated As levels in the Pannonian Basin are mainly present in very old (Palaeo) groundwater of methanogenic Pliocene/Quaternary aquifers, which is in contrast to Asian regions where arsenic-enriched groundwater is generally much younger. Display Omitted Research highlights: → Arsenic originates from Late Pliocene/Quaternary aquifers and some very old waters. → Arsenic levels are controlled by both mobilisation and retention mechanisms. → Mobilisation is caused by biogeochemical reductive dissolution. → Sufficient sulfate supply triggers arsenic retention in sulfide precipitates. → Nearly 500,000 people are exposed to elevated arsenic in their drinking water. - Abstract: Groundwater resources in the Pannonian Basin (Hungary, Romania, Croatia and Serbia) are known to contain elevated naturally occurring As. Published estimates suggest nearly 500,000 people are exposed to levels greater than the EU maximum admissible concentration of 10 μg/L in their drinking water, making it the largest area so affected in Europe. In this study, a variety of groundwaters were collected from Romania and Hungary to elucidate the general geochemistry and identify processes controlling As behaviour. Concentrations ranged from 4 2- reduction containing low As levels ( 7 Li (an indicator of geothermal inputs) and As(tot) in geothermal/saline influenced waters indicate that elevated As is not from an external input, but is released due to an in-aquifer process. Geochemical reasoning, therefore, implies As mobilisation is controlled by redox processes, most likely microbially mediated reductive dissolution of As bearing Fe-oxides, known to occur in sediments from the area. More important is an overlying retention mechanism determined by the presence or absence of SO 4 2- . Ongoing SO 4 2- reduction will release S 2- , removing As from solution either by the formation of As-sulfides, or from sorption onto Fe-sulfide phases. In methanogenic waters, As released

    In landscapes with low residence times (e.g., rivers and reservoirs), baseflow nutrient concentration dynamics during sensitive timeframes can contribute to deleterious environmental conditions downstream. This study assessed upland and in-stream controls on baseflow nutrient concentrations in a low-gradient, tile-drained agroecosystem watershed. We conducted time-series analysis using Empirical mode decomposition of seven decade-long nutrient concentration time-series in the agricultural Upper Big Walnut Creek watershed (Ohio, USA). Four tributaries of varying drainage areas and three main-stem sites were monitored, and nutrient grab samples were collected weekly from 2006 to 2016 and analyzed for dissolved reactive phosphorus (DRP), nitrate-nitrogen (NO3-N), total nitrogen (TN), and total phosphorus (TP). Statistically significant seasonal fluctuations were compared with seasonality of baseflow, watershed characteristics (e.g., tile-drain density), and in-stream water quality parameters (pH, DO, temperature). Findings point to statistically significant seasonality of all parameters with peak P concentrations in summer and peak N in late winter-early spring. Results suggest that upland processes exert strong control on DRP concentrations in the winter and spring months, while coupled upland and in-stream conditions control watershed baseflow DRP concentrations during summer and early fall. Conversely, upland flow sources driving streamflow exert strong control on baseflow NO3-N, and in-stream attenuation through transient and permanent pathways impacts the magnitude of removal. Regarding TN and TP, we found that TN was governed by NO3-N, while TP was governed by DRP in summer and fluvial erosion of P-rich benthic sediments during higher baseflow conditions. Findings of the study highlight the importance of coupled in-stream and upland management for mitigating eutrophic conditions during environmentally sensitive timeframes.

  12. Statistical assessment on a combined analysis of GRYN-ROMN-UCBN upland vegetation vital signs

    Irvine, Kathryn M.; Rodhouse, Thomas J.

    2014-01-01

    As of 2013, Rocky Mountain and Upper Columbia Basin Inventory and Monitoring Networks have multiple years of vegetation data and Greater Yellowstone Network has three years of vegetation data and monitoring is ongoing in all three networks. Our primary objective is to assess whether a combined analysis of these data aimed at exploring correlations with climate and weather data is feasible. We summarize the core survey design elements across protocols and point out the major statistical challenges for a combined analysis at present. The dissimilarity in response designs between ROMN and UCBN-GRYN network protocols presents a statistical challenge that has not been resolved yet. However, the UCBN and GRYN data are compatible as they implement a similar response design; therefore, a combined analysis is feasible and will be pursued in future. When data collected by different networks are combined, the survey design describing the merged dataset is (likely) a complex survey design. A complex survey design is the result of combining datasets from different sampling designs. A complex survey design is characterized by unequal probability sampling, varying stratification, and clustering (see Lohr 2010 Chapter 7 for general overview). Statistical analysis of complex survey data requires modifications to standard methods, one of which is to include survey design weights within a statistical model. We focus on this issue for a combined analysis of upland vegetation from these networks, leaving other topics for future research. We conduct a simulation study on the possible effects of equal versus unequal probability selection of points on parameter estimates of temporal trend using available packages within the R statistical computing package. We find that, as written, using lmer or lm for trend detection in a continuous response and clm and clmm for visually estimated cover classes with “raw” GRTS design weights specified for the weight argument leads to substantially

    2016-07-01

    Full Text Available Cultural Hungarian-Albanian relations during the Middle Ages are characterized by a relatively poor intensity. Actually, relations between these two countries are more intense in the political field and especially through the partnership between Gjergj Kastrioti Skanderbeg and John Hunyadi. Regarding the origin, the Hungarian culture identity is rather distinct from the Albanian one. Lack of cultural contacts, among others, was conditioned also by the fact that these relations were held under war circumstances and their primary aim was the common defense from Ottoman attacks. Actually, the Albanian medieval culture remained a Mediterranean culture with elements of Byzantine influence in the continental and southern areas. Meanwhile, Hungary belonged to Central Europe, which, even though far away from Mediterranean cultural mainstream, sought to be influenced by this culture, namely by the Renaissance that emanated exactly in the Mediterranean region. It was Matthias Corvinus effort, regarding the cultural influence of the Mediterranean and Renaissance in Hungary but also the fact that Hungary possessed some of the most important towns of the Adriatic coast and particularly Ragusa. This city was the center where cultural relations between Albanian and Hungary started and became intensified in the religious, intellectual and human field.

    The legal process of gender transition in Hungary had previously been more developed as in most European countries, as the law enabled transsexual people to change their name and gender before or without a medical treatment, which was unique at the time. Over the years, however, lots of European countries developed legal frameworks and accepted international standards of care for the treatment of gender dysphoria that Hungary did not follow. Currently in Hungary there is no consistent legal framework of gender transition, there is no official regulation or guidelines regarding gender transition process, no institution with the obligation to accommodate the process, and there is no nominated specialist in the state health care system whose remit included dealing with transsexual patients. The information on gender transition options both to the professionals and to the patients is limited and incoherent. This paper reviews the legal aspects and clinical management process of gender dysphoria in Hungary. Some issues regarding the Hungarian practice and possible solutions based on examples from the United Kingdom are addressed within the paper.

    Children's sleep duration is decreasing in the last decade. Despite of the well known negative consequences, there are no data on children's sleep duration in Hungary and Romania. The aim of the authors was to assess sleep duration of school-age children in Hungary and Romania. A self-edited questionnaire was used for the study. 2446 children were enrolled. All elementary and secondary schools in a Hungarian city, and one elementary and secondary school in a Romanian city took part in the study. Mean sleep duration was 8.3 ± 1.2 hours on weekdays. There was a significant difference between the two countries (Hungary vs. Romania, 8.5 ± 1.2 hours vs. 7.8 ± 0.9 hours, p = 0.001). Age correlated with sleep duration on weekdays (r= -0.605, p = 0.001), but not during weekend. This is the first study on children's sleep duration in Hungary and Romania. The difference between countries may be due to the difference in mean age or cultural and/or geographical differences.

    Full Text Available The contours of markets and entrepreneurship are shaped by historical and politico-institutional factors. In the case of Central and Eastern Europe, the development of new entrepreneurial classes is a function of communist legacies and post-1989 political processes. Employing survey data from 2000, this article examines how political and institutional conditions influence patterns of recruitment into self-employment and income returns to small entrepreneurship in Hungary, Poland, and Romania. The results of this analysis show that human capital (captured by education has positive significant effects on becoming a self-employed individual with employees in Hungary and Romania. As compared to other individuals, former socialist “petit bourgeois” (i.e., individuals who were business owners in 1988 are more likely to be small business operators in post-communism. Individuals who held managerial authority positions before 1989 have higher chances to become small business operators in Romania but not in Hungary or Poland. Unemployment seems to function as a push-factor for becoming a small business operator in Hungary and Poland but not in Romania. In Romania, most small entrepreneurs earn significantly more than employees in the state or private sector. Gender, age, and education have significant positive effects on income returns in all of the three countries under scrutiny.

  14. Probabilistic liquefaction hazard analysis at liquefied sites of 1956 Dunaharaszti earthquake, in Hungary

    Liquefaction potential evaluations are generally made to assess the hazard from specific scenario earthquakes. These evaluations may estimate the potential in a binary fashion (yes/no), define a factor of safety or predict the probability of liquefaction given a scenario event. Usually the level of ground shaking is obtained from the results of PSHA. Although it is determined probabilistically, a single level of ground shaking is selected and used within the liquefaction potential evaluation. In contrary, the fully probabilistic liquefaction potential assessment methods provide a complete picture of liquefaction hazard, namely taking into account the joint probability distribution of PGA and magnitude of earthquake scenarios; both of which are key inputs in the stress-based simplified methods. Kramer and Mayfield (2007) has developed a fully probabilistic liquefaction potential evaluation method using a performance-based earthquake engineering (PBEE) framework. The results of the procedure are the direct estimate of the return period of liquefaction and the liquefaction hazard curves in function of depth. The method combines the disaggregation matrices computed for different exceedance frequencies during probabilistic seismic hazard analysis with one of the recent models for the conditional probability of liquefaction. We have developed a software for the assessment of performance-based liquefaction triggering on the basis of Kramer and Mayfield method. Originally the SPT based probabilistic method of Cetin et al. (2004) was built-in into the procedure of Kramer and Mayfield to compute the conditional probability however there is no professional consensus about its applicability. Therefore we have included not only Cetin's method but Idriss and Boulanger (2012) SPT based moreover Boulanger and Idriss (2014) CPT based procedures into our computer program. In 1956, a damaging earthquake of magnitude 5.6 occurred in Dunaharaszti, in Hungary. Its epicenter was located

    Full Text Available This study focused on the clutch size and age-specific apparent survival rate of the Little Owl (Athene noctua population in Upper-Kiskunság, Hungary. Between May 2005 and April 2017, 640 individuals were captured and ringed in a total of 746 capture-recapture occasions. Artificial nest boxes were installed in the study area, breeding birds and pulli were captured for ringing/recaptured in these boxes (from March to May, or at the close neighbourhood of those (max. 168 m. Jolly-Seber’s open population method was applied to model the survival rate. The candidate model set included models incorporating age, year-effect, and the combination of those. AICc value was used to compare models in a selection approach. The final model was constructed via model averaging based on the models with significant explanatory power. The average number and SD of pullus/breeding pair was 3.78 ± 0.76. The average apparent annual survival rate (which does not differentiate between mortality and permanent emigration for the period between pullus stage and the time of the first breeding was estimated as 9.47% ± 2.99% SE, whereas the annual survival rate of adults was 82.74% ± 8.46% SE. The effect of sex on the survival rate of adults was not investigated due to female-biased sample, as the probability of capturing females is significantly higher in late spring months. Our experience reveals that during February and March it is possible to capture both sexes in the nest boxes, and it does not influence negatively the breeding success. Based on our results, the population of the Little Owl is stable in Upper-Kiskunság. A slight increase in estimated population size is observable even if we make no difference between mortality and permanent emigration. The high occupancy rate of the installed nest boxes reveals that nest site availability is an important limiting factor in the studied population.

    The potential of short rotation coppice as a biomass crop on land over 250m (the uplands) of mid Wales was studied. The results found in this study indicate that growing short rotation coppice willow in the uplands is a viable proposition with regard to establishment success and yields. In the event of a secure wood chip market in Wales, returns to the grower would be comparable to those from sheep production. (author)

  18. Student Mobility or Emigration Flow? The Case of Students Commuting from Serbia to Hungary

    Directory of Open Access Journals (Sweden)

    2015-04-01

    Full Text Available Student mobility between two European countries in transition, Hungary and Serbia, was considered for the period 2001-2010. The high motivation and number of Hungarian-speaking students emigrating/commuting to Hungary began in 1990, with the beginning of the Yugoslav Wars. In 2010, 1,385 Hungarian-speaking students (from Vojvodina, Serbia studied in Hungary and 3,152 in Serbia. Student mobility between Hungary and Serbia is highly concentrated and causes a very low returning rate of educated young elite (approximately 30%. For this reason, the future of the Hungarian minority has begun to be put into question in Serbia, in the Autonomous Province of Vojvodina, where their percentage within whole population is noticeably decreasing (1991: 16.9%, 2001: 14.3%. The research has been focused on answering the following questions: Are there integration conflicts in the autochthon minority within the state borders of Serbia? What can higher education offer to these students? Does the region offer enough to provide perspectives for young members of the elite? Will early student mobility end with continuous emigration? Empirical background: Interviews with young adult migrants from Serbia to Hungary; Location: Serbia. Objective: To examine the motives and willingness to emigrate among the Hungarian young adults/students from Vojvodina. Interview subjects: 18 university/college students or young adults with a diploma (from Vojvodina. It is important to note that only those young adults were interviewed who have returned to Serbia having finished their educational career or who are likely to come back later. Conclusions in brief: The Yugoslav Wars, worsening economic conditions, and low living standards have significantly influenced the willingness of the youth to migrate. The motives of migration among the Hungarian youth in Vojvodina are gaining professional experience, broadening knowledge, and improving language. Hungary is the first target country of

    During 1994, 1995, 1997, and 1998 expeditions across Mongolia, we located over 250 upland buzzard (Buteo hemilasius) nests. At these, we noted considerable morphological variation in plumage coloration and in leg pterylosis. In 1997 and 1998, we examined 131 nests scattered across eastern and central Mongolia and report here the tarsal condition of 119 nestlings from 59 broods where young were at least 2 weeks of age. Of 119 birds carefully examined, 50 (42%) had less than fully feathered tarsi and 4 of the 69 with fully feathered tarsi had scattered feathers on their toes. Thus, 54 of 119 birds (45%) in some way deviated from the feathered tarsibare toes condition. This extraordinary degree of variability in feather patterns may be best explained as the result of extensive and relatively recent hybridization between the longlegged (Buteo rufinus) and roughlegged (B. lagopus) buzzards and/or between long-legged and upland buzzards.

    Eocene climate and associated biotic patterns provide an analog system to understand their modern interactions. The relationship between mean annual temperatures and winter temperatures-temperature seasonality-may be an important factor in this dynamic. Fossils of frost-intolerant palms imply low Eocene temperature seasonality into high latitudes, constraining average winter temperatures there to >8 °C. However, their presence in a paleocommunity may be obscured by taphonomic and identification factors for macrofossils and pollen. We circumvented these problems by establishing the presence of obligate palm-feeding beetles (Chrysomelidae: Pachymerina) at three localities (a fourth, tentatively) in microthermal to lower mesothermal Early Eocene upland communities in Washington and British Columbia. This provides support for warmer winter Eocene climates extending northward into cooler Canadian uplands.

    After decades of fire suppression in eastern North America, land managers now are prioritizing prescribed fire as a management tool to restore or maintain fire-adapted vegetation communities. However, in long—fire-suppressed landscapes, such as the central and southern Appalachians, it is unknown how bats will respond to prescribed fire in both riparian and upland forest habitats. To address these concerns, we conducted zero-crossing acoustic surveys of bat activity in burned, unburned, riparian, and non-riparian areas in the central Appalachians, Virginia, USA. Burn and riparian variables had model support (ΔAICc fire differently between upland and riparian forest habitats, but overall, large landscape-level prescribed fire has a slightly positive to neutral impact on all bats species identified at our study site post—fire application.

    Full Text Available It is clear that demographic differentiation especially in rural areas and increasing alternative tourism activities in the Eastern Black Sea Region have been causing some social, cultural, economical and environmental changes both on uplands and transhumance activities. However, there is insufficient data on investigating these changes scientifically especially in the Eastern Black Sea where uplands and transhumance activities are important. Therefore, in this study, we tried to investigate how and why transhumance activities have been changing temporally by applying questionnaires and recording personal conversation with the local people who are still practicing transhumance activities in nine upland points chosen within the Fırtına Basin. In addition, we aimed to determine some ensued environmental issues and their reasons in the uplands. According to the results from the questionnaires, both the uplands themselves and the culture of the transhumance activities have been changing in general compared to the past. For example, it was determined that the rate of open chalets (wooden houses has dropped up to %15 and the number of livestock and animal husbandry practices have decreased in substantial amount, while number of people visiting the uplands with a recreational/touristic purpose has risen up to %63. Moreover, associated with the increase and diversification in tourism activities in the region, expansion of road building and structuring has reached the upper parts of the basins, setting up pressure for damaging vegetation cover and polluting natural resources such as water and soil.

    The distribution of exogenous DNA in upland cotton by pollen tube pathway was studied. The results showed that the exogenous DNA could be transported into ovules by dripping and injection. The optimum time for treatment is at 33 h after pollination. The radioactivity in ovules by dripping exogenous DNA was lower than that by injecting. In autoradiogram, the number of sliver grains in the treated ovules was more than that in the controls. (authors)

    Full Text Available Digital microscopy combines the benefits of traditional optical microscopy and the advantages of computer sciences. Using digital whole slides in all areas of pathology is increasingly popular. Telepathology or long distance diagnosis is one such area. In our study we have evaluated digital slide based histopathology diagnosis in an international setting, between Sweden and Hungary. Routine cases from the Sundsvall County Hospital (Landstinget Vasternorrland were collected. Glass slides were scanned using Pannoramic 250 Flash II. (3DHISTECH Ltd., Budapest, Hungary. During the first round of evaluation the glass slides were shipped to Hungary for primary diagnosis. Two pathologists from Hungary, reading glass slides and one pathologist from Sweden reading digital slides signed out 500 cases. Pathologists from Hungary reached the hospital information system with a secure connection. During the second round the pathologists in Hungary reevaluated 200 from the 500 cases using digital slides after three months washout period. Diagnostic accuracy was calculated and diagnostic errors was graded according to clinicopathological consequences. In 182/200 (91% cases digital and optical diagnoses were in full agreement. Out of the remaining 18 cases, 1 (0.5% critical error was identified. In this case the error had therapeutic and prognostic consequence and no uncertainty either because of case complexity or poor image quality was recorded by the pathologist. We think language and communication issues as well as differences in minimal data sets of pathological reports and in guidelines used in Sweden and in Hungary are factors potentially limiting the widespread use of digital slides in a teleconsultation service provided to Sweden from Hungary. We found the quality of digital slides in our study setting acceptable to reach correct primary diagnosis in routine, unselected, random cases of a small-to-medium sized pathology department in Sweden.

    The vitamin D3 formation in skin is the most important natural source of vitamin D demands of humans. The key step of the phototransformation of provitamin D into previtamin D from which the vitamin D3 is formed by thermal conversion. According to studies run at the latitudes of Hungary the UV-B radiation in winter time is not satisfactory to ensure the need of the vitamin D, which can result in vitamin D 3 deficiency and increases risk of osteoporosis. The aim of this study was to verify whether in the Hungarian population the UV radiation from the Sun ensures the daily synthesis of 1000 IU vitamin D3, or Vitamin D deficiency could occur in the winter and spring months which are less favourable in terms of UV exposure. The data of UV-B radiation reaching the Earth's surface were used for the evaluation. These data based on regular measurements in Budapest. According to the average of UV-B radiation of each months the "best case scenario" of vitamin D3 production was estimated by using the most optimal conditions of vitamin D synthesis. It was calculated, that the effective UV irradiance reaching the Earth's surface at noon in Budapest is the highest in July, while the lowest is in December. The difference between these two months is more than 35-fold for July. In the period between November and March more than 200 minutes have to be spent outdoor to ensure the production of satisfactory amount of vitamin D in skin. On one hand, it is irrealistically long time because it exceeds the duration of maximum irradiation around noon which was the basis of our calculation. On the other hand, if only the face and hands are uncovered then the required radiant exposure exceeds the 1 minimal erythemal dose, i.e. the skin would be burnt. Based on our calculations it was found, that in Budapest more than 95% of yearly effective UV-B radiation is measurable in the period between March and October. Therefore it can be assumed that the UV-B radiation would not be sufficient in the

    Upland red rice (Oryza sativa) contains anthocyanin, a phenolic compounds that can act as antioxidants and functional food for human dietary. The content of functional food on upland red rice is influenced by shading condition, but the production is also influenced by environmental condition, especially the availability of light. The study aims is to assess and analyze the effect of shade on the growth and production of upland red rice. The research was conducted using the quantitative method to obtain the optimal shading condition that can increase the rice anthocyanin content and relatively high production. The research was arranged in split plot design, with shade as main plot and the different of cultivar as sub plot with three replications. The shading treatment consist of 4 levels as follows: n1=shade level 75%. The cultivar tested were (v1) = Labandiri, (v2) = Jangkobembe, (v3) = Ranggohitam, and (v4) = Paedara. The rice planted in between teak wood trees with different age and level of canopy. The research reveals that shades had an effect in decreasing plant production (the higher level of shade, the higher the decrease level of production), but the shades can improve the quality of red rice through the increase of anthocyanin content.

    Developing water-saving rice cultivation is one important strategy for food security in China. This paper reported the experimental results of introducing six upland rice cultivars to eastern Keerqin sandy land. The field experiment results showed that under the condition of 60% water-saving, the yield of cultivars XH 95-13 and XH 95-13-6 was 10.2% and 5.5% higher than the control, respectively, while other four cultivars decreased by 6.7%-18.6%. Economically, all the cultivars except JP 121 had a higher income than the control, and the profitability of cultivars XH 95-13 and XH 95-13-6 reached 24.0% and 19.3%, respectively. The water productivity of all the six cultivars was over 0.566 kg x m(-3), increased by 59.89%-116.38%. Pot experiment showed that 12.1%-16.3% of soil moisture in 0-15 cm layer was beneficial to the growth of upland rice. In eastern Keerqin sandy land, effective tillers occurred before July 18. In brief, upland rice production could be extensively applicable in eastern Keerqin sandy land to gradually alternate the traditional lowland rice cultivation with continuous flooding, and save much underground water.

    Crop production in the Sahelian countries of Africa is limited by many factors. The most important are low potential yields of local varieties, low inherent soil fertility and low applications of external inputs (organic and mineral fertilizers). A field experiment was conducted from 2007 to 2008 with the objective to develop and validate screening protocols for plant traits that enhance N acquisition and utilization in upland rice grown in low N soils of two hundred (200) upland rice (Oryza sativa L.) genotypes from WAB, NERICA, CNA, CNAX, IRAT and IR lines. An experiment in small pots was carried out in a greenhouse of Farakoba research center. The pots were filled with a sandy soil and upland rice genotypes were grown during three weeks, harvested and studied for their root characteristics (seminal root length, adventitious root number, lateral root length and number and roots hair density). The small pot method was reliable for root trait characterisation at the seedling stage. A large variability among genotypes was exhibited for the root characteristics. The variability was larger within the NERICA and WAB lines compared to the other lines. The length of the seminal roots varied from 10 to 40 cm, the lateral root number ranged between 3 and 15 and the number of adventitious roots varied between 2 and 7. The selected root traits can be used to identify high nutrients and water use efficient genotypes. (author)

    The amount of standing dead and downed woody debris along an upland chromosequence was measured in an effort to investigate the role of fire-killed woody debris as a source of soil carbon in black spruce stands in Manitoba. Based on the measurement data and existing primary production values, a mass balance model was used to assess the potential impact of fire-killed wood on long-term carbon storage at this site. Long-term carbon was represented by the amount of carbon stored in deeper soil organic layers, persisting over millenia. Between 10 and 60 per cent of the deep-soil carbon was estimated to have been derived from wood biomass. The actual amount appears to be most affected by fire return interval, decay rate of wood, the amount of net primary production, and the decay rate of the post-fire carbon pool. Although the model was less sensitive to fire consumption rates and to rates at which standing dead wood becomes woody debris, all model runs clearly established that woody debris plays an important role in long-term carbon storage in this area. 53 refs., 4 tabs., 4 figs.

    The relationships between soil microbial properties and nitrous oxide emission were examined in upland soil under different tillage systems [no tillage (NT), rotary and plow tillage] and cover crop systems (fallow, cereal rye, and hairy vetch) in 2004 and 2005. Microbiological analyses included the determination of soil ergosterol as an indicator of fungal biomass, bacterial plate counting, and MPN estimations of ammonia oxidizers and denitrifiers. The combined practice of NT with rye-cover crop treatment increased fungal biomass but not bacterial populations in 0-10 cm deep soils. Such increase in fungal biomass was not found in 10-20 cm and 20-30 cm deep cover-cropped NT soil. The combined practice of NT with rye-cover cropping resulted in higher in situ N(2)O emission rates compared with rotary- and plow-till treatments. N(2)O flux was positively correlated with soil ergosterol content but not with denitrifier MPN and other soil chemical properties. These results suggested a significant contribution of fungi to N(2)O emission in cover-cropped NT soils.

    In the 1970s when Highway No. 3. was built in Hungary, environmental issues were not thoroughly considered. The main scope of our survey is the analyses of a gully created by the runoff from the highway and from the upper watershed. These excess waters were channeled into natural valleys alongside the highway. Five outlets were created where the runoff water developed deep gullies and deposited huge amount of sediment at the tail of the gullies. The surveyed gully can be found in central Hungary, at the border of Gödöllő city, which area belongs to the Gödöllő Hillside Landscape Protection District. The experimental area is situated 175-220 meters above the sea level and it is crossed by the M3 motorway which took part in the development of the surveyed linear erosion form. During our survey, several dams and channel modifications, buffer ditches were built from materials found mainly locally, in order to decrease the energy of waters, to hold up the runoff and this way to eliminate the erosion damage in this protected area. However it is difficult to install and to maintain the protective measures. Due to the nature protection status the possible use of the materials and methods are limited. We surveyed the longest gully, which is 320 meters long and its width is exceeding 3 meters at its head, close to the motorway. The average depth is 1 meter. In order to monitor the amount of the runoff we planted some rods, where the height aboveground was known. The survey was made with GPS (Global Position System- Trimble Juno SB ArcPad 8.0) where along the gully the GPS recorded the position in every 20 seconds. Besides we recorded every dams and every sudden changes, where the direction, slope angle, depth, width or other characteristic was different. The data processing and the maps was made in ArcMap10.2, QGIS 2.2 and in Google Earth. Furthermore, micro soil profiles were taken from the riverbed to know the thickness of the runoff after bigger rainfall events. The

    Organizations engaged in drug addiction treatment started their activities only recently in Hungary. This paper examines the organisational environment in drug outpatient treatment using the example of Blue Point Foundation (BPF), a non-governmental organization (NGO). The authors describe BPF's organizational structure and functioning related to its effectiveness. BPF staff members anonymously completed a 59-item questionnaire about its organizational characteristics and functioning. The questionnaire covered demographic data, 50 items of the Quality Control questionnaire and a SWOT (Strengths, Weakness, Opportunities, Threats) analysis. Policy and strategy were considered BPF's best feature, while the management of funds received the lowest rating. The assessment of the staff and that of the organization as a whole was closer to the midpoint of the scale. High risk of staff burnout and unstable organizational environment are the most important threats on the NGOs working in addictology in Hungary.

    My poster presentation is about a process of communication with public during big social events like festivals, open days and sport’s competitions. The technique is: we make a WiN stand on the frequent place of events, invite visitors and kindly ask them to fill our questionnaire about nuclear industry in Hungary. The questionnaire contents 15 questions about Hungarian NPP (how many units we have, what is electrical output). We communicate with visitors during the filling a questionnaire and after that we check the result. We can see the level of knowledge of our guest and give them the appropriate information on their level. Usually every participant takes a small present with the emblem of WiN Hungary. This form of communication has tested many times in our activity. It works very effectively. The form of poster is a chart flow of the process illustrated with photos. (author)

    Suicide is not only a contradictory biological, psychological, sociocultural and spiritual phenomenon, but also a serious public health problem, which is manifold, therefore the fight against it is also complex. The aim of the present publication is to establish the current situation of the fight against suicide in Hungary, which are the most important deficits, contradictions and unexploited possibilities. The author states that although we have accomplished important steps in the prevention of suicide, we did not realise the majority of them in everyday practice. The author defines the most important problems and tasks which should be solved in the next decade. In the near future a great deal more should be done for prevention than what we have accomplished so far in order to significantly reduce the number of suicide victims in Hungary.

    In 1950s Hungary, with an economy and infrastructure still devastated from World War II and facing further hardships, thousands of children became permanently disabled and many died in the severe polio epidemic that shook the globe. The relatively new communist regime invested significantly in solving the public health crisis, initially importing a vaccine from the West and later turning to the East for a new solution. Through the history of polio vaccination in Hungary, this article shows how Cold War politics shaped vaccine evaluation and implementation in the 1950s. On the one hand, the threat of polio created a safe place for hitherto unprecedented, open cooperation among governments and scientific communities on the two sides of the Iron Curtain. On the other hand, Cold War rhetoric influenced scientific evaluation of vaccines, choices of disease prevention, and ultimately the eradication of polio.

    Full Text Available In the process of transformation in old socialist country in Eastern Europe in 1989, a large scale insolvent debenture emerges. Hungary, Poland and the Czech Republic which drove Eastern Europe's economy, use insolvent loan to solve this insolvent debenture and these three countries also make the government bonds as money supply funding patterns. But Hungary and Poland use decentralized solution and leading banks to deal with the bad creditor. On the contrary, Czech has no special way of dealing with that, but let some certain bank mainly focusing on the bad creditor which is called centralized solution. Now, Korean government is using the similar method like Czech. In this point of view, in order avoid insolvent debenture becoming the burden of economy, Korea has to work out the same plan to deal with insolvent debenture with Poland.

    In recent years, the number of cases of disease caused by canine parvovirus 2 (CPV-2) in vaccinated dogs has increased. The aim of the present study was to identify CPV-2 strains present in Hungary. Forty-two out of 50 faecal specimens examined were positive, and 25 VP2 sequences were determined and analysed. Based on the current classification, the Hungarian viruses belong to New CPV-2a type, except two viruses that are recombinants of vaccine viruses and CPV-2a strains. The Tyr324Ile alteration was detected for the first time in Europe, and a "Hungarian-specific" substitution (Ala516Thr) was also identified in this study. The immunologically important parts of the currently spreading canine parvoviruses were examined and found to differ greatly from the vaccine strains that are widely used in Hungary.

    The organic-moderated and cooled nuclear reactor concept has stimulated extensive activities in numerous different areas of research. Investigations started in Hungary in 1958 do not cover all topics of interest in organic reactors and so far no projects have been started to build such a reactor. Since OMRE and other organic reactor experiments have already shown the potential use of organic materials as reactor coolants and moderators, efforts have been focused rather on the investigation and solution of certain specific particular problems and also on economic aspects. One of the most important objectives seems to be a better knowledge of the radiolytic heat transfer and neutron physics behaviour of organic liquids. In Hungary the following topics were selected for investigation: Radiation stability of organic compounds and their mixtures; Heat-transfer studies; Investigations on the moderating parameters of organic liquids; Economic analysis of the possible use of organic reactors for process heat application

    Adolescent health behaviours are influenced by a variety of social factors, including social orientations, such as social comparison or competitiveness. The main goal of the present study was to investigate the role that these social orientations might play in health behaviours (both health-impairing and health-promoting). Data were collected from high school students (N = 548; ages 14-20 years; 39.9% males) in two counties of the Southern Plain Region of Hungary. The self-administered questionnaires contained items on sociodemographics, such as age, sex, parental schooling, and socioeconomic status (SES) self-assessment; school achievement, health behaviours, competitiveness and social comparison. Multiple regression analyses suggest that those who scored higher on competitiveness engaged in more substance use, a pattern that was not present for health-promoting behaviours. Social comparison, however, was associated with lower levels of substance use. In addition, in relation to health-impairing behaviours, both competitiveness and social comparison interacted with sex; both social orientation variables proved to be more important for boys. Social comparison also contributed to health-promoting behaviours among boys. Findings support the idea that the role of social orientations, such as competitiveness and social comparison, can be quite different depending on sex and the nature of the health behaviour. While competitiveness may act as a risk factor for substance use among boys, social comparison may act as a protection. It appears that social orientations play less of a role in girls' health-related behaviours. More focus is needed on gender differences in influences on adolescents' health-related behaviours. Les comportements de santé des adolescents sont influencés par une variété de facteurs sociaux, incluant les orientations sociales telles que la comparaison sociale ou la compétitivité.

    1977-01-01

    At present the source of the energy consumption per person increases with 3.6% yearly in the world and this rate is estimated to be 2.8% in 2000. In Hungary the increase of the energy demands was 4.2% and in the following years it will be 4%. The ratio of the hydrocarbons will yet increase and the ratio of coal will decrease till 1980. The amount of the imported energy has always been significant and will further increase. The quantity of the fissile materials is about 1% of the whole energy store in the world. The problem can be temporarily solved by breeder reactors but the permanent solution can be based on solar energy or on the utilization of nuclear fusion. Participation of the nuclear energy in the world's energy production is still 1-2% but it increases quickly. At present the light water reactors dominate over the gas-cooled and heavy water reactors. There are a lot of problems in connection with breeder reactors. (V.N.)

    Tritium occurs in nature in trace amounts, but its concentration is changing due to natural and artificial sources. Studies focusing on natural tritium have to take into account the effect of artificial sources. Also, the impact of tritium is an important issue in environmental protection, e.g. in connection with the emissions from nuclear power plants. The present work focuses on the rain washout of tritium emitted from the Paks nuclear power plant in Hungary. Rainwater collectors were placed around the plant and after a period of precipitation, rainwater was collected and analysed for tritium content. Samples were analysed using low-level liquid scintillation counting, with some also subject to the more accurate (3)He ingrowth method. The results clearly show the trace of the tritium plume emitted from the plant; however, values are only about one order of magnitude higher than environmental background levels. A washout model was devised to estimate the distribution of tritium around the plant. The model gives slightly higher concentrations than those measured in the field, but in general the agreement is satisfactory. The modelled values demonstrate that the effect of the plant on rainwater tritium levels is negligible over a distance of some kilometres. Copyright © 2010 Elsevier Ltd. All rights reserved.

    Recently, Hepatozoon canis infection has been detected among shepherd, hunting and stray dogs in the southern part of Hungary, which is considered to be free of Rhipicephalus sanguineus sensu lato and close to the border with Croatia. The aim of this study was to acquire information on the possibility that red foxes and/or golden jackals could play a role in the appearance and spread of H. canis in Hungary. A conventional PCR was used to amplify a 666 bp long fragment of the Hepatozoon 18S rRNA gene from blood samples collected from 334 foxes shot in 231 locations in 16 counties and 15 golden jackals shot in 9 locations in two southwestern counties close to Croatia. A second PCR assay was performed in some of the samples positive by the first PCR to amplify a larger segment (approximately 1500 bp) of the 18S rRNA gene of Hepatozoon spp. for further phylogenetic analysis. Hepatozoon infection was detected in canids shot in 30 locations and 9 counties. Altogether 26 foxes (8.0%, 95% CI: 5-11%) and 9 jackals (60%, 95% CI: 33-81%) were PCR positive. Hepatozoon canis sequences were obtained from 12 foxes and 7 jackals. DNA sequences from 16 animals were 99-100% similar to H. canis from Croatian foxes or dogs while two of the sequences were 99% similar to an Italian fox. Half (13/26) of the infected red foxes and all golden jackals were shot in the two southwestern counties. This is the first report on molecular evidence of H. canis in red foxes (Vulpes vulpes) and golden jackals (Canis aureus) from Hungary, which is considered free from the tick vector of H. canis, R. sanguineus. Although no R. sanguineus sensu lato had been found on infected or non-infected wild canids, the detection of authochnous canine hepatozoonosis in Hungary might imply that the range of R. sanguineus sensu lato has reached this country.

    2004-12-01

    Full Text Available In this paper the author examines the situation of the Roma minority in present-day Hungary. First he gives a short overview, summarizing Roma history in all of Europe from the time of their arrival, especially in regard to Hungary. He presents general information on the language and on some cultural-civilisational traits of the Roma in the past and compares former assimilational tendencies formulated in the atmosphere of enlightened absolutism with similar tendencies that appeared and were implemented in many European countries in the more recent period. The author directs special attention to the economic, social and educational aspects of the Roma theme in Hungary, and presents some indications concerning the images the Hungarian majority has of the Roma minority. To a certain degree he analyses the structure of prejudices towards the Roma, in relation to the social strata from which they come. Most of his data derives from research conducted on the theme of the Roma in Hungary during the last fifteen years. The question of the educational structure of the Roma population is analysed primarily in regard to how much it enables employment. A poor educational structure and the impossibility to find employment are indicated as the main problems preventing the full integration of the Roma into present-day Hungarian society. Finally, the author analyses the role of civil society associations in resolving the problems of the Roma, with a special note on strictly Roma organisations as forms of minority self-government. Some examples are given also of the penetration of modern mass culture into the collective cultural identificational code of the Roma minority. These cultural elements, alongside Roma traditions that are still maintained and nurtured, help to increase the self-consciousness of the Roma, but they also stimulate interests in the rest of the population and in this way sensitivise the general population towards the Roma theme.

    Trichinella spiralis and Trichinella britovi are the two most common species of the genus Trichinella persisting in the European wildlife. To investigate the spatial distribution of these Trichinella spp. and the factors influencing their circulation in Hungary, 3304 red foxes (Vulpes vulpes) and 0.29 million wild boars (Sus scrofa) were tested for Trichinella sp. infection in Hungary from 2006 to 2013. Trichinella spp. larvae from 68 (2.06%) foxes and 44 (0.015%) wild boars were identified by a multiplex PCR as T. britovi or T. spiralis. The locality of origin of foxes and wild boars were recorded in a geographic information system database. There was no correlation between environmental parameters in the home range of foxes and wild boars and the T. spiralis larval counts, but there was a positive correlation between the boundary zone of Hungary and T. spiralis infection (Pdistribution of T. spiralis in the Hungarian wildlife is determined by the transborder transmission of the parasite from the surrounding endemic countries. Multiple regression analysis was performed with environmental parameter values and T. britovi larval counts. Based on the statistical analysis, non-agricultural areas (forests, scrubs, herbaceous vegetation and pastures) and the mean annual temperature (Pdeterminants of the spatial distribution of T. britovi in Hungary. The positive relationship with non-agricultural areas can be explained by the generalist feeding behaviour including scavenging of foxes in these areas. The negative relationship with the mean annual temperature can be attributed to the slower decomposition of wildlife carcasses favouring a longer survival of T. britovi larvae in the host carrion and to the increase of scavenging of foxes.

    A detailed geogenic radon potential (GRP) mapping based on field soil gas radon and soil gas permeability measurements was carried out in this study. A conventional continuous variable approach was used in this study for GRP determination and to test its applicability to the selected area of Hungary. Spatial pattern of soil gas radon concentration, soil permeability and GRP and the relationship between geological formations and these parameters were studied by performing detailed spatial analysis. Exploratory data analysis revealed that higher soil gas radon activity concentration and GRP characterizes the mountains and hills than the plains. The highest values were found in the proluvial–deluvial sediments, rock debris on the downhill slopes eroded from hills. Among the Quaternary sediments, which characterize the study area, the fluvial sediment has the highest values, which are also located in the hilly areas. The lowest values were found in the plain areas covered by drift sand, fluvioeolic sand, fluvial sand and loess. As a conclusion, radon is related to the sediment cycle in the study area. A geogenic radon risk map was created, which assists human health risk assessment and risk reduction since it indicates the potential of the source of indoor radon. The map shows that low and medium geogenic radon potential characterizes the study area in central Hungary. High risk occurs only locally. The results reveal that Quaternary sediments are inhomogeneous from a radon point of view, fluvial sediment has medium GRP, whereas the other rock formations such as drift sand, fluioeolic sand, fluvial sand and loess, found in the study area, have low GRP. - Highlights: • First geogenic radon potential map in Hungary. • Low and medium GRP characterizes the study area (Middle Hungary). • Mainly quaternary sediments characterizes the study area. • Radon is related to the erosion and deposition of the sediment cycle

    The measuring station of the 10 MW VVR-SM research reactor at the Budapest Neutron Centre (Hungary) was used to perform dynamic neutron radiography (DNR), which was, to our best knowledge, the first time, in a Tortella tortuosa biotope. In the conducted study, two trophical levels, moss and spider Thomisidae sp. juv., were examined. Cadmium penetration routes, distribution and accumulation zones were visualized in the leafy gametophyte life cycle of Tortella tortuosa and in the organs of the spider.

    Full Text Available Our study describes fundamental changes in childbearing behavior in Hungary. It documents current postponement of entry into motherhood (first birth and uncovers signs of delay in second birth. We place the behavioral modifications into historical time and reveal the basic role of the political, economic, and societal transformation of Hungary that started in 1989-1990 in these modifications. We document postponement as well as differentiation, and mothers' highest level of education will represent the structural position of individuals. We shed light on the different speed of postponement and support the assumption of behavioral differences according to the highest level of education. Particular attention will be paid to changing partnership relations: Fertility outcomes remain to be strongly associated with the type of partnership and its development; profound changes in partnership formation, namely the proliferation of cohabitation and the increasing separation rate of first partnerships, may therefore facilitate fertility decline in Hungary. The analysis is based on the first wave of the Hungarian panel survey "Turning points of the life course" carried out in 2001/2002.

  13. Conclusions from the last five years of experiments in the field of food irradiation in Hungary

    Science.gov (United States)

    Kálmán, B.

    For the beginning of the eighties Hungary was ready to introduce the radiation technology in the food industry and the authority of the country decided to establish a joint venture to use this technology in large scale. AGROSTER Co started to irradiate food packaging material and some type of spices for the meat industry. The policy of the AGROSTER was to increase the irradiated food items very slowly from one year to another and the same time using a good, marketing to convince of the all interested persons about the benefit of the food irradiation technology in Hungary. A gamma irradiator is used by this company which was built for application research since this plant was very useful in this initial stage in spite of the low source efficiency. It can be said the used step by step strategy of AGROSTER was very success because in the last year the radiation capacity of its gamma facility was used as much as possible to irradiate food items and the government of Hungary recognized the benefit of this technology and gives financial assistance to establish a large commercial gamma irradiator in Budapest.

  14. Continued improvement of cardiovascular mortality in Hungary - impact of increased cardio-metabolic prescriptions

    Full Text Available Abstract Background During the last 35 years the poor ranking of Hungary on the list of life expectancy at birth among European countries, has not changed. In 1970 our lag behind the leading European countries was the smallest. The gap was growing between 1970 and 1993 but from 1994 onwards the life expectancy at birth in Hungary has increased continuously and somewhat faster than in other European countries. The aim of this study was to analyze the association between decreasing cardiovascular mortality rates, as a main cause of death and the increase in cardio-metabolic prescriptions and possible changes in lifestyle behavior. Methods Analyses were conducted on national data concerning cardiovascular mortality and the number of cardio-metabolic drug prescription per capita. The association between yearly rates of cardiovascular events and changes in antihypertensive, antilipidemic and antidiabetic prescription rates was analyzed. The changes in other cardiovascular risk factors, like lifestyle were also considered. Results We observed a remarkable decline of mortality due to stroke and acute myocardial infarction (AMI. The fall was significantly associated with all prescription rates. The proportion of each treatment type responsible for suppression of specific mortality rates is different. All treatment types comparably improved stroke mortality, while antilipidemic therapy improved AMI outcome. Conclusions These results emphasize the importance of a comprehensive strategy that maximizes the population coverage of effective treatments. Hungary appears to be at the beginning of the fourth stage of epidemiologic transition, i.e. it has entered the stage of delayed chronic noninfectious diseases.

    The rapid socioeconomic transition in post-communist Hungary adversely affected the overall morbidity and mortality rates in the 1990s. Prevalence data on depressive disorders from the region are still scarce, however. This study reports the findings of the first epidemiological survey, using the Edinburgh Postnatal Depression Scale (EPDS) and the Beck Depression Inventory (BDI), on the prevalence of post-partum depression and the associated risk factors in Hungary. A total of 1030 mothers who delivered their babies between May and July 1999 in 16 counties in Hungary were screened for depressive symptoms 3-26 weeks post-partum. The survey found that 10.81% of the sample was above the cut-off score of 13, and the EPDS detected post-partum depressive symptoms with 76% (95% confidence interval (CI)=60.5-87.1) sensitivity and 92% (95% CI=90.5-94.1) specificity. In addition, 24 socio-demographic, socio-psychiatric data and personal and obstetric variables were surveyed. Results of a hierarchical logistic regression analysis showed that depression of the mother during pregnancy was the strongest predictor of depressive symptoms post-partum. Depression before pregnancy, housing conditions, marital relationship status and family history of alcohol problems were also identified as predictors for post-partum depressive symptoms.

  16. Innovation in Hungary - The Impact of EU Accession and Integration into Global Value Chains

    Directory of Open Access Journals (Sweden)

    Szalavetz Andrea

    2014-11-01

    Full Text Available This paper argues that EU accession has brought about minimal changes in the patterns of innovation in Hungary. The reason why is not that the ‘EU factor’ is of minor importance; rather, it is Hungary's inability to use EU resources effectively, so as to fully benefit from EU membership. The Hungarian story also demonstrates that the EU cannot block member states from reversing reform or abusing the opportunities EU membership offers to them. We contend that globalization (global value chain integration has more effectively contributed to Hungary's knowledge-based upgrading than Europeanization (in the sense of policy transfer; access to EU Structural & Cohesion Funds, and integration in the European Research Area. This argument is substantiated with a case study on innovation strategy design and implementation, which illustrates the ambiguous impact of Europeanization, which is contrasted with our investigation of integration in global value chains, conducted through interviews of foreign-owned manufacturing companies about their R&D-based upgrading experience.

    In Hungary reliability analysis (RA) and probabilistic safety assessment (PSA) of nuclear power plants was initiated 3 years ago. First, computer codes for automatic fault tree analysis (CAT, PREP) and numerical evaluation (REMO, KITT1,2) were adapted. Two main case studies - detailed availability/reliability calculation of diesel sets and analysis of safety systems influencing event sequences induced by large LOCA - were performed. Input failure data were taken from publications, a need for failure and reliability data bank was revealed. Current and future activities involves: setup of national data bank for WWER-440 units; full-scope level-I PSA of PAKS NPP in Hungary; operational safety assessment of particular problems at PAKS NPP. In the present article the state of RA and PSA activities in Hungary, as well as the main objectives of ongoing work are described. A need for international cooperation (for unified data collection of WWER-440 units) and for IAEA support (within Interregional Program INT/9/063) is emphasized. (author)

    The aim of this study was to assess the Staphylococcus aureus nasal carriage rate in healthy children all over Hungary and to specify some risk factors, the antibiotic resistance patterns of the bacteria, and their genetic relatedness. In total, 878 children (aged 3-6 years) were screened at 21 day-care centers in 16 different cities in Hungary, between February 2009 and December 2011. Samples taken from both nostrils were cultured on blood agar, and suspected S. aureus isolates were identified by β-hemolysis, catalase positivity, clump test, and nucA PCR. Methicillin-resistant strains were screened by mecA and mecC PCR. Antibiotic susceptibility was determined by agar dilution or gradient test strips. Pulsed-field gel electrophoresis was used for genotyping. S. aureus carriage rate was found to be 21.3%, which correlates well with international data. We found no statistically significant correlation between the gender or the sibling status and S. aureus carriage. All isolates were sensitive to oxacillin, trimethoprim-sulfamethoxazole, and mupirocin. The resistance rates for erythromycin, ciprofloxacin, clindamycin, gentamicin, and tetracycline were 7.5%, 0.5%, 1.1%, 3.7%, and 4.3%, respectively. The isolates showed very high genetic diversity. In summary, carried S. aureus isolates are more sensitive to antibiotics compared with clinical isolates in Hungary, and methicillin-resistant S. aureus carriage rate is very low yet.

    Complete text of publication follows. Objective: To give a review of cancer mortality data among Hungarian radiation workers in nuclear industry in comparison with the results of the international nuclear workers' study prevailing the size of the study group of all former studies. Methods: Retrospective cohort study including 598,068 workers of 154 nuclear establishments in 15 countries (AUS, BEL, CAN, FIN, FRA, GER, HUN, JAP, LIT, ROK, SLK, SPA, SWE, UK, USA) coordinated by the International Agency for Research on Cancer (IARC, Lyon, France). The national study was extended for an additional 4-year period. Results: In the international study 407,391 persons in 13 years of average employment received 19.4 mSv mean cumulative dose, while in the national study 3322 radiation workers of Nuclear Power Plant (NPP) Paks, Hungary, in 14 years of follow-up period accumulated in average 5.13 mSv, only. There were 5233 cancer deaths registered in the international study, associated with an estimated ERR of 0.97 per Sv. Thus, 19.4 mSv recorded cumulative dose can explain 1 to 2% of cancer death cases. In radiation workers of NPP, Paks, during the period of 1985-1998 there were 40 cancer deaths observed against the expected 58.8 cases. In a further four year period (1999-2002) 29 cancer death cases were identified vs. the expected 65.5 cases. The SMR for the cancer death cases registered in recent and former radiation workers of NPP, Paks in the 18-year follow-up period is 56%. The SMR from all causes was even lower, 40% only. Conclusions: In the international study the mean accumulated radiation dose received by nuclear workers in 13 years is below of the recent annual dose limit (20 mSv/yr of the effective dose). The average value for the whole of radiation workers in 15 countries is almost 4-times higher of that registered in Hungary. The 'healthy worker effect' in the nuclear industry, and particularly in Hungary has been proven, once again. Nevertheless, the results

  20. Laboratory incubation experiments assessing the factor interactions affecting urine-derived nitrous oxide emissions from spatially and temporally variable upland pastures

    Urine patches deposited to soils by grazing animals represent hot-spots of nitrous oxide (N2O) emissions (Hargreaves et al., 2015), a powerful greenhouse gas (GHG) and precursor of ozone depletion in the stratosphere. Urine N2O emissions are produced via nitrification of ureolysis-derived ammonium (NH4+) and/or subsequent nitrite (NO2-) and nitrate (NO3-) denitrification (Kool et al., 2006). The dominant process and the N2O fluxes generated depend on interactions between urine characteristics (e.g. nitrogen [N] concentration and volume), soil characteristics (e.g. carbon [C] availability and pH) and preceding and prevailing environmental conditions (e.g. soil moisture and temperature; Bergstermann et al., 2011; Butterbach-Bahl et al., 2013; Dijkstra et al., 2013). The spatial and temporal variability of these interactions in grazing systems is potentially large and greatly increases the uncertainty associated with N2O emission estimates from such systems. In particular, the contribution of extensively managed upland agroecosystems, which occupy ca. 5.5 million hectares in the UK and provide the bulk of land for sheep farming (Pollott & Stone, 2004), to UK GHG emissions is poorly defined. Improving understanding of the interactions between the wide range of factors affecting urine-derived N2O production and emission from pasture soils and considering this in the context of the spatial and temporal variability of the grazing environment could therefore be extremely valuable in improving the accuracy of N2O emission estimates from such systems. The factorial laboratory incubation experiments presented have been designed to assess the interactive effects of factors such as urine N concentration, volume and soil moisture affecting soil N2O (and nitric oxide [NO], nitrogen gas [N2] and carbon dioxide [CO2]) production and emissions (García-Marco et al., 2014) using the state-of-the-art Denitrification Incubation System (DENIS). This work forms part of a wider project

    The tropical montane forests in the Colombian Andean region are located above 1500 m, and have been heavily deforested. Despite the general presumption that productivity and hence carbon stocks in these ecosystems are low, studies in this regard are scarce. This study aimed to (i) to estimate Above Ground Biomass (AGB) in forests located in the South of the Colombian Andean region, (ii) to identify the carbon storage potential of tropical montane forests dominated by the black oak Colombobalanus excelsa and to identify the relationship between AGB and altitude, and (iii) to analyze the role of tropical mountain forests in conservation mechanisms such as Payment for Environmental Services (PES) and Reducing Emissions from Deforestation and Degradation (REDD+). Twenty six 0.25 ha plots were randomly distributed in the forests and all trees with D > or =10 cm were measured. The results provided important elements for understanding the role of tropical montane forests as carbon sinks. The information produced can be used in subnational initiatives, which seek to mitigate or reduce the effects of deforestation through management or conservation of these ecosystems, like REDD+ or PES. The AGB and carbon stocks results obtained were similar to those reported for lowland tropical forests. These could be explained by the dominance and abundance of C. excelsa, which accounted for over 81% of AGB/carbon. The error associated with the estimates of AGB/carbon was 10.58%. We found a negative and significant relationship between AGB and altitude, but the higher AGB values were in middle altitudes (approximatly = 700-1800 m), where the environmental conditions could be favorable to their growth. The carbon storage potential of these forests was higher. However, if the historical rate of the deforestation in the study area continues, the gross emissions of CO2e to the atmosphere could turn these forests in to an important emissions source. Nowadays, it is clear that tropical

  2. Assessing soil calcium depletion following growth and harvesting of Sitka spruce plantation forestry in the acid sensitive Welsh uplands

    1998-01-01

    Full Text Available A simple mass balance has been used to estimate soil calcium depletion during the growth of a 50 year old Sitka spruce crop on acid, base-poor peaty podzol soils in upland Wales. Growth of the crop will deplete the soil calcium reserve by an amount (205 kg Ca ha-1 approximately equivalent to the exchangeable calcium pool to the bottom of the profile and equal to 14% of the total soil calcium reserve to the bottom of the B horizon. Despite these predictions, measurements of exchangeable calcium show no differences beneath mature forest and acid grassland, implying that i weathering rates in forest soils are greater than long-term estimates and predictions by the PROFILE soil chemistry model ii the trees can access other sources of calcium or iii there are significant errors in the mass balance. Following stem-only harvesting, growth of a 50 year old second rotation crop will lead to further depletion of soil calcium, but this amount (79 kg Ca ha-1, is less than for a second rotation crop following whole-tree harvesting (197 kg Ca ha-1. After the first crop, stem-only harvesting would allow a further 18 rotations before depletion of the total calcium reserve to the bottom of the B horizon. Whole-tree harvesting would allow for seven rotations after the first crop. These calculations assume that all sources of calcium are equally available to the crop. This can only be resolved by dynamic modelling of the calcium cycle at the ecosystem scale based on appropriate field measurements. The potential for significant soil acidification is therefore greater following whole-tree harvesting and, in line with current recommendations (Nisbet et al., 1997, this technique should probably be avoided on acidic, nutrient-poor soils unless remedial measures are included to enhance the soil base cation status.

  3. Deploying a Proximal Sensing Cart to Identify Drought-Adaptive Traits in Upland Cotton for High-Throughput Phenotyping

    Full Text Available Field-based high-throughput phenotyping is an emerging approach to quantify difficult, time-sensitive plant traits in relevant growing conditions. Proximal sensing carts represent an alternative platform to more costly high-clearance tractors for phenotyping dynamic traits in the field. A proximal sensing cart and specifically a deployment protocol, were developed to phenotype traits related to drought tolerance in the field. The cart-sensor package included an infrared thermometer, ultrasonic transducer, multi-spectral reflectance sensor, weather station, and RGB cameras. The cart deployment protocol was evaluated on 35 upland cotton (Gossypium hirsutum L. entries grown in 2017 at Maricopa, AZ, United States. Experimental plots were grown under well-watered and water-limited conditions using a (0,1 alpha lattice design and evaluated in June and July. Total collection time of the 0.87 hectare field averaged 2 h and 27 min and produced 50.7 MB and 45.7 GB of data from the sensors and RGB cameras, respectively. Canopy temperature, crop water stress index (CWSI, canopy height, normalized difference vegetative index (NDVI, and leaf area index (LAI differed among entries and showed an interaction with the water regime (p < 0.05. Broad-sense heritability (H2 estimates ranged from 0.097 to 0.574 across all phenotypes and collections. Canopy cover estimated from RGB images increased with counts of established plants (r = 0.747, p = 0.033. Based on the cart-derived phenotypes, three entries were found to have improved drought-adaptive traits compared to a local adapted cultivar. These results indicate that the deployment protocol developed for the cart and sensor package can measure multiple traits rapidly and accurately to characterize complex plant traits under drought conditions.

  4. Investigation of the Influence of Leaf Thickness on Canopy Reflectance and Physiological Traits in Upland and Pima Cotton Populations

    2017-08-01

    Full Text Available Many systems for field-based, high-throughput phenotyping (FB-HTP quantify and characterize the reflected radiation from the crop canopy to derive phenotypes, as well as infer plant function and health status. However, given the technology's nascent status, it remains unknown how biophysical and physiological properties of the plant canopy impact downstream interpretation and application of canopy reflectance data. In that light, we assessed relationships between leaf thickness and several canopy-associated traits, including normalized difference vegetation index (NDVI, which was collected via active reflectance sensors carried on a mobile FB-HTP system, carbon isotope discrimination (CID, and chlorophyll content. To investigate the relationships among traits, two distinct cotton populations, an upland (Gossypium hirsutum L. recombinant inbred line (RIL population of 95 lines and a Pima (G. barbadense L. population composed of 25 diverse cultivars, were evaluated under contrasting irrigation regimes, water-limited (WL and well-watered (WW conditions, across 3 years. We detected four quantitative trait loci (QTL and significant variation in both populations for leaf thickness among genotypes as well as high estimates of broad-sense heritability (on average, above 0.7 for both populations, indicating a strong genetic basis for leaf thickness. Strong phenotypic correlations (maximum r = −0.73 were observed between leaf thickness and NDVI in the Pima population, but not the RIL population. Additionally, estimated genotypic correlations within the RIL population for leaf thickness with CID, chlorophyll content, and nitrogen discrimination (r^gij = −0.32, 0.48, and 0.40, respectively were all significant under WW but not WL conditions. Economically important fiber quality traits did not exhibit significant phenotypic or genotypic correlations with canopy traits. Overall, our results support considering variation in leaf thickness as a potential

    Richardson, Claire A.

    1982-01-01

    This report, describing ground-water occurrence in a 130-square-mile area of the central Maryland Piedmont, was originally designed for use by the U.S. Environmental Protection Agency in replying to a request for designation of the aquifers to be the sole or principal source of ground water. However, the information contained in the report is pertinent to other crystalline-rock areas as well. The study area is underlain chiefly by crystalline rocks and partly by unaltered sandstones and siltstones. The ground water is derived from local precipitation and generally occurs under water-table conditions. Its movement is restricted by the lack of interconnected openings, and most ground water occurs within 300 feet of the land surface. Hydrographs indicate no long-term change in ground-water storage. A few wells yield more than 100 gallons per minute, but about 70 percent of 286 inventoried wells yield 10 gallons per minute or less; most specific capacities are less than 1.0 gallon per minute per foot. The ground-water quality is generally satisfactory without treatment, and there are no known widespread pollution problems. Estimated daily figures on ground-water use are as follows: 780,000 gallons for domestic purposes; 55,000, for commercial purposes; and 160,000, for public supply. Although part of the area is served by an existing surface-water supply and could be served by possible extension of it and of other public-supply water mains, much of the rural population is dependent on the ground water available from private wells tapping the single aquifer that underlies any given location. Neither the ground-water conditions nor this dependence on individual wells is unique to the study area, but, rather, applies to the entire Piedmont province.

    Soil organic matter (SOM) content in paddy soils is higher than that in upland soils in tropical and subtropical China. The dissolved organic matter (DOM) concentration, however, is lower in paddy soils. We hypothesize that soil moisture strongly controls the fate of DOM, and thereby leads to differences between the two agricultural soils under contrasting management regimens. A 100-day incubation experiment was conducted to trace the fate and biodegradability of DOM in paddy and upland soils under three moisture levels: 45%, 75%, and 105% of the water holding capacity (WHC). {sup 14}C labeled DOM, extracted from the {sup 14}C labeled rice plant material, was incubated in paddy and upland soils, and the mineralization to {sup 14}CO{sub 2} and incorporation into microbial biomass were analyzed. Labile and refractory components of the initial {sup 14}C labeled DOM and their respective half-lives were calculated by a double exponential model. During incubation, the mineralization of the initial {sup 14}C labeled DOM in the paddy soils was more affected by moisture than in the upland soils. The amount of {sup 14}C incorporated into the microbial biomass (2.4–11.0% of the initial DOM-{sup 14}C activity) was less affected by moisture in the paddy soils than in the upland soils. At any of the moisture levels, 1) the mineralization of DOM to {sup 14}CO{sub 2} within 100 days was 1.2–2.1-fold higher in the paddy soils (41.9–60.0% of the initial DOM-{sup 14}C activity) than in the upland soils (28.7–35.7%), 2) {sup 14}C activity remaining in solution was significantly lower in the paddy soils than in the upland soils, and 3) {sup 14}C activity remaining in the same agricultural soil solution was not significantly different among the three moisture levels after 20 days. Therefore, moisture strongly controls DOM fate, but moisture was not the key factor in determining the lower DOM in the paddy soils than in the upland soils. The UV absorbance of DOM at 280 nm

    Cotton, one of the world's leading crops, is important to the world's textile and energy industries, and is a model species for studies of plant polyploidization, cellulose biosynthesis and cell wall biogenesis. Here, we report the construction of a plant-transformation-competent binary bacterial artificial chromosome (BIBAC) library and comparative genome sequence analysis of polyploid Upland cotton (Gossypium hirsutum L.) with one of its diploid putative progenitor species, G. raimondii Ulbr. We constructed the cotton BIBAC library in a vector competent for high-molecular-weight DNA transformation in different plant species through either Agrobacterium or particle bombardment. The library contains 76,800 clones with an average insert size of 135 kb, providing an approximate 99% probability of obtaining at least one positive clone from the library using a single-copy probe. The quality and utility of the library were verified by identifying BIBACs containing genes important for fiber development, fiber cellulose biosynthesis, seed fatty acid metabolism, cotton-nematode interaction, and bacterial blight resistance. In order to gain an insight into the Upland cotton genome and its relationship with G. raimondii, we sequenced nearly 10,000 BIBAC ends (BESs) randomly selected from the library, generating approximately one BES for every 250 kb along the Upland cotton genome. The retroelement Gypsy/DIRS1 family predominates in the Upland cotton genome, accounting for over 77% of all transposable elements. From the BESs, we identified 1,269 simple sequence repeats (SSRs), of which 1,006 were new, thus providing additional markers for cotton genome research. Surprisingly, comparative sequence analysis showed that Upland cotton is much more diverged from G. raimondii at the genomic sequence level than expected. There seems to be no significant difference between the relationships of the Upland cotton D- and A-subgenomes with the G. raimondii genome, even though G

    Graphical abstract: Elevated As levels in the Pannonian Basin are mainly present in very old (Palaeo) groundwater of methanogenic Pliocene/Quaternary aquifers, which is in contrast to Asian regions where arsenic-enriched groundwater is generally much younger. Display Omitted Research highlights: {yields} Arsenic originates from Late Pliocene/Quaternary aquifers and some very old waters. {yields} Arsenic levels are controlled by both mobilisation and retention mechanisms. {yields} Mobilisation is caused by biogeochemical reductive dissolution. {yields} Sufficient sulfate supply triggers arsenic retention in sulfide precipitates. {yields} Nearly 500,000 people are exposed to elevated arsenic in their drinking water. - Abstract: Groundwater resources in the Pannonian Basin (Hungary, Romania, Croatia and Serbia) are known to contain elevated naturally occurring As. Published estimates suggest nearly 500,000 people are exposed to levels greater than the EU maximum admissible concentration of 10 {mu}g/L in their drinking water, making it the largest area so affected in Europe. In this study, a variety of groundwaters were collected from Romania and Hungary to elucidate the general geochemistry and identify processes controlling As behaviour. Concentrations ranged from <0.5 to 240 {mu}g/L As(tot), with As predominantly in the reduced As(III) form. Using cluster analysis, four main groups of water were identified. Two groups (1 and 2) showed characteristics of water originating from reducing aquifers of the area with both groups having similar ranges of Fe concentrations, indicating that Fe-reduction occurs in both groups. However, As levels and other redox characteristics were very different. Group 1, indicative of waters dominated by methanogenesis contained high As levels (23-208 {mu}g/L, mean 123 {mu}g/L), with group 2 indicative of waters dominated by SO{sub 4}{sup 2-}reduction containing low As levels (<0.5-58 {mu}g/L, mean 11.5 {mu}g/L). The remaining two groups

    Reacting upon the increasing concern of possible harmful effects due to radon, more and more countries established, or intend to establish in the near future, legislation for the radon level both for homes and workplaces. The dose due to radon seems to be more complicated to assess for workplaces than for homes, although the basic principles of dose estimation are the same. The doses at workplaces need to be estimated by individual approaches, but such requirement is usually not reflected in the legislations. The present study deals with characteristic situations and refers to findings and considerations in the cases of offices, schools, underground workplaces, and open air working situations with relatively high radon level. It discusses the possible inaccuracies caused by the improper selection of time periods and methods in the measurements of the average radon concentration. The purpose of this paper is to provide some examples (mainly based on the authors' experiences) to show difficulties that might emerge in the determination of average radon concentrations in various workplaces. This will help choose the proper measurement methods for each case and contribute to the regulator's work in the precise and unambiguous legislation phrasing. (author)

    Selection of pre-embryogenic callus from a core structure from mature seed-derived callus is the key for high-efficiency plant regeneration and transformation of switchgrass different cultivars. Switchgrass (Panicum virgatum L.) has been identified as a dedicated biofuel crop. For its trait improvement through biotechnological approaches, we have developed a highly efficient plant regeneration and genetic transformation protocol for both lowland and upland cultivars. We identified and separated a pre-embryogenic "core" structure from the seed-derived callus, which often leads to development of highly regenerative type II calluses. From the type II callus, plant regeneration rate of lowland cultivars Alamo and Performer reaches 95%, and upland cultivars Blackwell and Dacotah, 50 and 76%, respectively. The type II callus was also amenable for Agrobacterium-mediated transformation. Transformation efficiency of 72.8% was achieved for lowland cultivar Alamo, and 8.0% for upland cultivar Dacotah. PCR, Southern blot and GUS staining assays were performed to verify the transgenic events. High regenerative callus lines could be established in 3 months, and transgenic plants could be obtained in 2 months after Agrobacterium infection. To our knowledge, this is the first report on successful plant regeneration and recovery of transgenic plants from upland switchgrass cultivars by Agrobacterium-mediated transformation. The method presented here could be helpful in breaking through the bottleneck of regeneration and transformation of lowland and upland switchgrass cultivars and probably other recalcitrant grass crops.

    Typical paddy and upland soils were collected from a hilly subtropical red-soil region. 14C-labeled dissolved organic carbon (14C-DOC) was extracted from the paddy and upland soils incorporated with 14C-labeled straw after a 30-day (d) incubation period under simulated field conditions. A 100-d incubation experiment (25 degrees C) with the addition of 14C-DOC to paddy and upland soils was conducted to monitor the dynamics of 14C-DOC mineralization under different soil moisture conditions [45%, 60%, 75%, 90%, and 105% of the field water holding capacity (WHC)]. The results showed that after 100 days, 28.7%-61.4% of the labeled DOC in the two types of soils was mineralized to CO2. The mineralization rates of DOC in the paddy soils were significantly higher than in the upland soils under all soil moisture conditions, owing to the less complex composition of DOC in the paddy soils. The aerobic condition was beneficial for DOC mineralization in both soils, and the anaerobic condition was beneficial for DOC accumulation. The biodegradability and the proportion of the labile fraction of the added DOC increased with the increase of soil moisture (45% -90% WHC). Within 100 days, the labile DOC fraction accounted for 80.5%-91.1% (paddy soil) and 66.3%-72.4% (upland soil) of the cumulative mineralization of DOC, implying that the biodegradation rate of DOC was controlled by the percentage of labile DOC fraction.

    A pot trial was conducted to investigate the effects of three arbuscular mycorrhizal (AM) fungi species, including Glomus geosporum BGC HUN02C, G. versiforme BGC GD01B, and G. mosseae BGC GD01A, on grain yield and arsenic (As) uptake of upland rice (Zhonghan 221) in As-spiked soils. Moderate levels of AM colonization (24.1-63.1 %) were recorded in the roots of upland rice, and up to 70 mg kg(-1) As in soils did not seem to inhibit mycorrhizal colonization. Positive mycorrhizal growth effects in grain, husk, straw, and root of the upland rice, especially under high level (70 mg kg(-1)) of As in soils, were apparent. Although the effects varied among species of AM fungi, inoculation of AM fungi apparently enhanced grain yield of upland rice without increasing grain As concentrations in As-spiked soils, indicating that AM fungi could alleviate adverse effects on the upland rice caused by As in soils. The present results also show that mycorrhizal inoculation significantly (p rice production when growing in As-contaminated soils.

    Rice paddies constitute almost a fifth of global cropland and provide more than half of the world's population with staple food. At the same time, they are a major source of methane and therewith significantly contribute to the current warming of Earth's atmosphere. Despite their apparent importance in the cycling of carbon and other elements, however, the microorganisms thriving in rice paddies are insufficiently characterized with respect to their biomolecules. Hardly any information exists on human-induced alteration of biomolecules from natural microbial communities in paddy soils through varying management types (affecting, e.g., soil or water redox conditions, cultivated plants). Here, we determined the influence of different land use types on the distribution of glycerol dialkyl glycerol tetraethers (GDGTs), which serve as molecular indicators for microbial community structures, in rice paddy (periodically flooded) and adjacent upland (non-flooded) soils and, for further comparison, forest, bushland and marsh soils. To differentiate local effects on GDGT distribution patterns, we collected soil samples in locations from tropical (Indonesia, Vietnam and Philippines) and subtropical (China and Italy) sites. We found that differences in the distribution of isoprenoid GDGTs (iGDGTs) as well as of branched GDGTs (brGDGTs) are predominantly controlled by management type and only secondarily by climatic exposition. In general, upland soil had higher crenarchaeol contents than paddy soil, which by contrast was more enriched in GDGT-0. The GDGT-0 / crenarchaeol ratio, indicating the enhanced presence of methanogenic archaea, was 3-27 times higher in paddy soils compared to other soils and increased with the number of rice cultivation cycles per year. The index of tetraethers consisting of 86 carbons (TEX86) values were 1.3 times higher in upland, bushland and forest soils than in paddy soils, potentially due to differences in soil temperature. In all soils br

    Background: Inorganic arsenic (iAs) is a potent carcinogen, but there is a lack of information about cancer risk for concentrations iAs exposure iAs metabolism. Methods: The Arsenic Health Risk Assessment and Molecular Epidemiology (ASHRAM) study, a case–control study, was conducted in areas of Hungary, Romania, and Slovakia with reported presence of iAs in groundwater. Consecutively diagnosed cases of basal cell carcinoma (BCC) of the skin were histologically confirmed; controls were general surgery, orthopedic, and trauma patients who were frequency matched to cases by age, sex, and area of residence. Exposure indices were constructed based on information on iAs intake over the lifetime of participants. iAs metabolism status was classified based on urinary concentrations of methylarsonic acid (MA) and dimethylarsinic acid (DMA). Associations were estimated by multivariable logistic regression. Results: A total of 529 cases with BCC and 540 controls were recruited for the study. BCC was positively associated with three indices of iAs exposure: peak daily iAs dose rate, cumulative iAs dose, and lifetime average water iAs concentration. The adjusted odds ratio per 10-μg/L increase in average lifetime water iAs concentration was 1.18 (95% confidence interval: 1.08, 1.28). The estimated effect of iAs on cancer was stronger in participants with urinary markers indicating incomplete metabolism of iAs: higher percentage of MA in urine or a lower percentage of DMA. Conclusion: We found a positive association between BCC and exposure to iAs through drinking water with concentrations < 100 μg/L. PMID:22436128

    In this paper we characterized several weathering profiles developed on granitoid rocks in the Sila Massif upland (Calabria, southern Italy), integrating detailed macro- and micromorphological observations with physico-mechanical field tests and petrographic, mineralogical and geochemical analyses. We focused our attention on the main weathering and pedogenetic processes, trying to understand apparent discrepancies between weathering grade classes based on field description and geomechanical properties, and two common weathering indices, such as the micropetrographic index (Ip) and the chemical index of alteration (CIA). Our results showed that sericite on plagioclase and biotite chloritization, that represent inherited features formed during late-stage hydrothermal alteration of granitoid rocks, may cause an overestimation of the real degree of weathering of primary mineral grains under meteoric conditions, especially in lower weathering grade classes. Moreover, the frequent identification of Fe-Mn oxides and clay coatings of illuvial origin (rather than or in addition to those formed in situ), both at the macro- and microscale, may also explain an overestimation of the weathering degree with respect to field-based classifications. Finally, some apparent inconsistencies between field geomechanical responses and chemical weathering were interpreted as related to physical weathering processes (cryoclastism and thermoclastism), that lead to rock breakdown even when chemical weathering is not well developed. Hence, our study showed that particular caution is needed for evaluating weathering grades, because traditional field and geochemical-petrographic tools may be biased by inherited hydrothermal alteration, physical weathering and illuvial processes. On the basis of chronological constraints to soil formation obtained from a 42 ka-old volcanic input (mixed to granite parent materials) detected in the soil cover of the Sila Massif upland, a first attempt to estimate

    Developing a deep root system is an important strategy for avoiding drought stress in rice. Using the 'basket' method, the ratio of deep rooting (RDR; the proportion of total roots that elongated through the basket bottom) was calculated to evaluate deep rooting. A new major quantitative trait locus (QTL) controlling RDR was detected on chromosome 9 by using 117 recombinant inbred lines (RILs) derived from a cross between the lowland cultivar IR64, with shallow rooting, and the upland cultivar Kinandang Patong (KP), with deep rooting. This QTL explained 66.6% of the total phenotypic variance in RDR in the RILs. A BC(2)F(3) line homozygous for the KP allele of the QTL had an RDR of 40.4%, compared with 2.6% for the homozygous IR64 allele. Fine mapping of this QTL was undertaken using eight BC(2)F(3) recombinant lines. The RDR QTL Dro1 (Deeper rooting 1) was mapped between the markers RM24393 and RM7424, which delimit a 608.4 kb interval in the reference cultivar Nipponbare. To clarify the influence of Dro1 in an upland field, the root distribution in different soil layers was quantified by means of core sampling. A line homozygous for the KP allele of Dro1 (Dro1-KP) and IR64 did not differ in root dry weight in the shallow soil layers (0-25 cm), but root dry weight of Dro1-KP in deep soil layers (25-50 cm) was significantly greater than that of IR64, suggesting that Dro1 plays a crucial role in increased deep rooting under upland field conditions.

    Land-use conversion is an important factor influencing the carbon and nitrogen gas exchange between land and atmosphere, and soil microorganisms is main driver of soil carbon and nitrogen gas production. Understanding the effect of land-use conversion on soil microbial communities and its influencing factor is important for greenhouse gas emission reduction and soil organic carbon and nitrogen sequestration and stability. The influence of land use conversion on soil process was undergoing a dynamic change, but little research has been done to understand the effect on soil microbial communities during the initial years after land conversion. In the study, the influences of land-use conversion from double rice cropping (RR) to maize-maize (MM) and soybean-peanut (SP) double cropping systems on soil physical and chemical properties, and microbial community structure was studied after two years of the conversion in southern China. The results showed that land use conversion significantly changed soil properties, microbial communities and biomass. Soil pH significantly decreased by 0.50 and 0.52 after conversion to MM and SP, respectively. Soil TN and NH4-N also significantly decreased by 9%-15% and 60% after conversion to upland fields, respectively. The total PLFAs, bacterial, gram-positive bacterial (G+), gram-negative bacterial (G-) and actinomycetic PLFAs decreased significantly. The ng g-1 soil concentration of monounsaturated chain PLFAs 16:1ω7c and 18:1ω9t were significantly higher at paddy fields than at upland fields. No significant differences in soil properties, microbial communities and biomass were found between conversed MM and SP. Our results indicated that land use conversion, not crop type conversed had a significant effects on soil properties and microbial communities at the initial of land conversion. And soil pH was the key factor regulating the variations in soil microbial community structure after land use conversion from paddy to upland fields.

    Mountain peatlands are susceptible to a changing climate via changes in the water cycle. Understanding the impacts of such changes requires knowledge of the hydrological processes within these peatlands and in the upland forests that supply them with water. We investigated hydrological processes in peatland catchments in the Rocky Mountains by developing empirical models of groundwater dynamics, and are working to improve subsurface water dynamics in a ecohydrological process model, the Terrestrial Regional Ecosystem Exchange Simulator (TREES). Results from empirical models showed major differences in water budget components between two peatlands with differing climate, vegetation, and hydrogeological settings. Several-fold higher rates of evapotranspiration from the saturated zone, and groundwater inflow were observed for a sloping fen in southern Wyoming than that of a basin fen in southwestern Colorado, where rainfall was two-fold higher due to stronger influence of the North American monsoon. We also present ongoing work coupling stable water isotope and borehole nuclear magnetic resonance analyses to test which soil water pools (bound or mobile) are used by dominant upland and peatland vegetation in two catchments in southern Wyoming. These data are being used to test whether the root hydraulic mechanisms in TREES can simulate water uptake from these two soil water pools, and sap flux measurements are being used to evaluate simulated transpiration. Preliminary results from this work suggest that upland vegetation utilize tightly-bound soil water pools, as these pools comprise the largest amount of subsurface water (> 80%) in the vadose zone long after snow melt. Conversely, it appears that herbaceous peatland hydrophytes may preferentially utilize mobile soil water pools, since their roots extend below the water table. The results of this work are expected to increase predictive understanding of hydrological processes in these important ecosystems.

    The laboratories of the Radiological Monitoring and Data Acquisition Network act within the organizational frame of the National Public Health and Medical Officers Service (NPHMOS). The tasks of the network are defined by the duties of Ministry of Health, Social and Family Affairs in the field of environmental radiation protection and radiation hygiene under normal situation and radiological emergency, as well. The monitoring program includes the measurements of samples and radionuclides necessary for estimation of the radiation burden of population. On the basis of measurements and dose assessment it can be stated that the effective dose of the Hungarian population from man-made sources (3.6 μSv x y -1 ) is almost three orders of magnitude lower than the dose from natural radiation sources.

    Full Text Available Limestone (karst surfaces in Hungary are rich in dolines, in which many endangered vascular plant species occur. To date, the majority of studies dealing with doline vegetation have focused on the local rather than the landscape level, without using comparative data from other areas. However, in this study we aimed to compare the vegetation pattern and species composition of dolines under different climate regimes of Hungary with regard to regional species pools. The fieldwork was carried out between 2005 and 2012. Twenty dolines were selected in the Mecsek Mountains (southern Hungary and nine dolines in the Aggtelek Karst area (northern Hungary. More than 900 vascular plants and more than 2000 plots were included in the study. The moving split window (MSW technique, nestedness analysis and principal coordinates analysis (PCoA were used to reveal the vegetation patterns in dolines. Although we found remarkable differences between the species composition of the two regions, dolines of both regions play a similar role in the preservation of different groups of species. Many plants, in particular mountain species, are restricted to the bottom of dolines where appropriate environmental conditions exist. In addition, depending on the doline geometry, many species of drier and warmer forests have colonized the upper slopes and rims. Thus, we can conclude that karst dolines of Hungary can be considered as reservoirs for many vascular plant species, therefore they are particularly important from a conservation point of view. Moreover, these dolines will likely become increasingly indispensable refugia for biodiversity under future global warming.

    The European Union (EU) will be increasingly dependant upon non-EU primary energy resources as domestic resources are depleted. Ukraine can play a pivotal role in future supply to the EU through its neighbor Hungary. Ukraine is the largest country in the world by volume of gas transit. Through its pipeline, the transit gas deliveries amount annually to 140 billion m{sup 3}, including 120 billion m{sup 3} to countries of Central and Western Europe. The country also has an under-utilized 750 kV electricity transmission line that reaches into Hungary. These assets make Eastern Hungary a key location for a Combined Cycle Gas Turbine (CCGT). A plant of this type would be able to provide electricity generation for the Central Eastern Europe (CEE) region. The heat generated by the plant could also be used in local industrial and agricultural production, thereby providing an additional impetus for regional development initiatives. Hungary is open for foreign investment from the West, but also from investors in the Ukraine and Russia. The construction of the CCGT plant and the related regional development is a great opportunity to strengthen the cooperation of Ukraine, the EU and Hungary for the common benefit of the entire region.

    IYPE activities of various geo-science associations, universities, research institutes and private companies in Hungary (www.foldev.hu) have been successfully coordinated by the Hungarian National Committee, which was established by the Hungarian Academy of Sciences, the UNESCO- and the IUGS National Committees. The National Launch Event (April 17, 2008) was followed with a four-days long "Earth Science Fair" at the Hungarian Natural History Museum in Budapest. The IYPE was even briefly reviewed in the Hungarian Parliament. The Science Festival, organized annually by the Hungarian Academy of Sciences, in 2008 had a special IYPE-inspired slogan: "Science for the Habitable Earth", where lectures were held about the modern content of the Greek Classical Elements ("earth", "water", "air" and "fire", that is energy) and about the Humanity. In 2008/2009 numerous publications (including the Hungarian version of the IYPE booklet series, under the title GEO-FIFIKA, the Természet Világa special issue in February 2009, the IYPE number of Földrajzi Közlemények (Geographical Communications), and the "Geological Map of Hungary for Tourists" were produced. Throughout the country, symposia (e.g. HUNGEO 2008, ELGI 100, MÁFI 140, Geotourism Symposium in October 2009), several contests (Hungarian Television "Delta", Élet és Tudomány on the occasion of the UN year, and the annual contests starting in 2007 at Miskolc University), film shows (e.g., the movie "Another Planet") and other performances (e.g. End of the Ice Age in Hungarian Natural History Museum) were organized, with modest but increasing media coverage. The worldwide premier of the Planet Earth TV took place in Hungary, on the occasion of the IAGA 11th Scientific Assembly (August 23-30, 2009, www.iaga2009sopron.hu). One of our conferences ("Earth and Heaven - Geology and Theology") pointed out that there should be no conflict between science and religion, either in the fields of Earth's history or evolution

Feed and drinking water given by farmers identified for 14 days and extracted sampling for mineralanalysis, t-test was used to compare mineral status in upland and lowland. Results of the research showed that feed given by farmers were varying. The ratio of forage/concentrates in lowland and upland areas was different, i.e. 67: 33 and 30: 70, respectivelly. Ca content on forage given in upland areas ranged from 0.17 to 0.74%, and concentrates from 0.002 to 0.49%, while Ca content on forage given in lowland areas ranged from 0.33 to 0.52%, and concentrates ranged from 0.38 to 0.49%. P content on forage in upland areas ranged from 0.02 to 0.04%, concentrates ranged from 0.018 to 0.09%,while P content on forage in lowland areas ranged from 0.03 to 0.07%, and concentrates ranged from 0.04 to 0.07% . Ca and P consumption in upland areas were 301.06 and 54.73 g, and 391.92 and 65.70 g in lowland.Caand P content of beef cattle’s hair in upland were 0.14 and 0.01%, while in lowland areas were 0.11 and 0.03%.It can be concluded that Ca and P intakeof beef cattle in Jratunseluna river basin were less and mineral status of Ca and P in marginal condition.

    Full Text Available This paper aims to give a brief and preliminary assessment of Hungarian views on the One Belt and One Road Initiative (BRI. The preliminary nature of the paper derives from the fact that the BRI is still in the making, and it will be for the years to come, thus its framing must constantly change as well. The author intends partly to analyse the media coverage of the BRI in Hungary and partly to evaluate academic papers on the very subject. This evaluation is to be carried out by relying on how events, information and commentaries related to the initiative are represented in the Hungarian media and at the same time, it makes attempts to organize, classify arguments pro and contra, and interpret narratives from the views derived from. The paper only studies Hungarian-language materials published in Hungary, and it does not seek to investigate other Hungarian materials published in the neighbouring countries. One of the reasons for that is that different political environments change the focus of the discussions significantly, in particular in Hungarian communities living in countries like Serbia or Ukraine that are not members of the European Union. The other reason is that traditionally foreign policies have different focuses, f. ex. the Romanian diplomacy has a strong US-orientation, while the Serbian foreign policy is Russia-oriented. In other words, China’s interpretation is less positive than in Hungary since the cultural, political and economic backgrounds are different. In this paper, academic papers will receive special attention since Hungarian pundits and researchers potentially influence Hungarian decision-makers, thus the Hungarian policy. The mapping of Hungarian think-tanks has the goal to show what are the basic elements of critical, supportive commentaries, though the author is aware that being a Hungarian researcher does not make the analysis of the Hungarian academic world easier.

    Human alveolar echinococcosis, caused by the metacestode stage of Echinococcus multilocularis, is one of the most pathogenic zoonoses in the temperate and arctic region of the Northern Hemisphere. To investigate the spatial distribution of E. multilocularis and the factors influencing this distribution in the recently identified endemic area of Hungary, 1612 red fox (Vulpes vulpes) carcasses were randomly collected from the whole Hungarian territory from November 2008 to February 2009 and from November 2012 to February 2013. The topographic positions of foxes were recorded in geographic information system database. The digitized home ranges and the vector data were used to calculate the altitude, mean annual temperature, annual precipitation, soil water retention, soil permeability, areas of land cover types and the presence and buffer zone of permanent water bodies within the fox territories. The intestinal mucosa from all the foxes was tested by sedimentation and counting technique. Multiple regression analysis was performed with environmental parameter values and E. multilocularis counts. The spatial distribution of the parasite was clumped. Based on statistical analysis, mean annual temperature and annual precipitation were the major determinants of the spatial distribution of E. multilocularis in Hungary. It can be attributed to the sensitivity of E. multilocularis eggs to high temperatures and desiccation. Although spreading and emergence of the parasite was observed in Hungary before 2009, the prevalence and intensity of infection did not change significantly between the two collection periods. It can be explained by the considerably lower annual precipitation before the second collection period. Copyright © 2013 Elsevier B.V. All rights reserved.

    The most commonly used building materials in Hungary and in numerous country of the world are the bricks, which made from clays. Due to the congenial internal structure properties of the clays these raw materials can be mixed with other materials, provides great possibility to reuse industrial by-products as additive material. The production and inbuilt of new types of synthetic building materials based on NORM (naturally occurring radioactive materials) by-products is raising concerns among authorities, public and scientists. Several NORM residues produced in large quantity, such as: phospogypsum (phosphate industry), red mud (aluminium processing industry), fly ash, coal slag (coal burning and steelworks) and so on are presently under investigation. The aluminum manufacturing in Ajka (Hungary) started in 1943. As a result of the bauxite refining activities up to now approximately 30 Mt of red mud has been produced in Hungary, stored in reservoirs. The radionuclide content of the bauxite usually exceeds the world average in soils (WA), which entirely remains in the by-product during Bayer process. The exposure pathways in case of application of NORM residues have to be explored in order to reveal the potential risks of NORMs on residents. The gamma radiation originated from the primordial radionuclides (K-40; U-238; Th-232) and their daughter elements found in nature and in building materials as well increase the external dose of the human body. In the EU the Radiation Protection 112 (RP 112) guideline serves for classification of building material, wherein the gamma exposure is limited by I-index

  9. Assessment and visualization of uncertainty for countrywide soil organic matter map of Hungary using local entropy

    Uncertainty is a general term expressing our imperfect knowledge in describing an environmental process and we are aware of it (Bárdossy and Fodor, 2004). Sampling, laboratory measurements, models and so on are subject to uncertainty. Effective quantification and visualization of uncertainty would be indispensable to stakeholders (e.g. policy makers, society). Soil related features and their spatial models should be stressfully targeted to uncertainty assessment because their inferences are further used in modelling and decision making process. The aim of our present study was to assess and effectively visualize the local uncertainty of the countrywide soil organic matter (SOM) spatial distribution model of Hungary using geostatistical tools and concepts. The Hungarian Soil Information and Monitoring System's SOM data (approximately 1,200 observations) and environmental related, spatially exhaustive secondary information (i.e. digital elevation model, climatic maps, MODIS satellite images and geological map) were used to model the countrywide SOM spatial distribution by regression kriging. It would be common to use the calculated estimation (or kriging) variance as a measure of uncertainty, however the normality and homoscedasticity hypotheses have to be refused according to our preliminary analysis on the data. Therefore, a normal score transformation and a sequential stochastic simulation approach was introduced to be able to model and assess the local uncertainty. Five hundred equally probable realizations (i.e. stochastic images) were generated. The number of the stochastic images is fairly enough to provide a model of uncertainty at each location, which is a complete description of uncertainty in geostatistics (Deutsch and Journel, 1998). Furthermore, these models can be applied e.g. to contour the probability of any events, which can be regarded as goal oriented digital soil maps and are of interest for agricultural management and decision making as well.

    Full Text Available This paper explores the relationship between migration, entrepreneurship, and foreign direct investments by focusing on entrepreneurial activities of post-Soviet (immigrants in Hungary in periods between 1991 and 2016. Post-Soviet migrants are in focus because between 1956 and 1989 the Soviet Union coercively kept Hungary in the Socialist bloc. Based on surveys and in-depth interviews, this paper reveals that there are considerable differences in patterns of entrepreneurship among post-Soviet immigrant entrepreneurs depending mostly on time of their arrival to Hungary. Similarly, motives for entrepreneurship among the first-wave migrants combine negative factors in the former Soviet Union with positive factors encountered in Hungary, while factors in Hungary recognized as positive by most post-Soviets prevail in motives for later waves of post-Soviet migration and entrepreneurship in Hungary. The paper also demonstrates that many relatively small investments have been conducted since 2000 by citizens of post-Soviet countries to Hungary. Some of them are transforming into an entrepreneurial activity, serving also as a basis for immigration to Hungary.

    In long-term dose assessment models for radioactive waste disposal, an important exposure pathway to humans is via ingestion of contaminated foods. In order to obtain soil-to-plant transfer factors (TFs) of radionuclides under equilibrium conditions, naturally existing elements were measured as analogues of radionuclides. Crops grown in upland fields and associated soil samples were collected from 62 sampling sites throughout Japan. The total concentrations of 52 elements in the crops and 54 elements in the soil samples were measured. The TFs of 40 elements (Li, Na, Mg, Al, Si, P, K, Ca, Ti, V, Cr, Mn, Fe, Co, Ni, Cu, Zn, As, Se, Rb, Sr, Y, Mo, Cd, Sn, Cs, Ba, La, Ce, Pr, Nd, Sm, Eu, Gd, Dy, Ho, Er, Pb, Th and U) were calculated on a dry weight basis. Among all the TF data, K showed the highest TF with a geometric mean (GM) of 2.1, followed by P. The GMs of TFs for rare earth elements, Th and U were on the order of 10 -4 . Most of the TF-GMs for green vegetables were higher than GMs of all crops for the elements. The obtained TFs of some elements for green vegetables and potatoes were compared with those in the technical report series-364 (TRS-364) compiled by IAEA in 1994. The TF-GMs were usually lower than the best estimates (expected values) listed in TRS-364; however, the GMs of TF for La and TF for Th observed for potatoes were slightly higher than the expected values.

    Full Text Available Grain proteins from 58 Brazilian and nine Japanese upland rice cultivars (Oryza sativa L. were electrophoretically separated by sodium dodecyl sulfate-polyacrylamide gel electrophoresis (SDS-PAGE. Densitometric scanning of the electrophoretic profiles permitted the estimation of the relative concentration of 16 protein fractions, which were used as variables for the calculation of Fisher's canonical discriminating functions. Significant differences between mean values of protein fractions were useful in distinguishing Brazilian and Japanese cultivars, as well as improved and non-improved Brazilian rice cultivars in scattered plots. Electrophoretically detectable protein polymorphism in rice grain can indicate geographic origin as well as breeding improvement level of a cultivar. Improved cultivars were those released by plant breeding institutes.Proteínas de grão de 58 genótipos de arroz brasileiro e nove japoneses foram separadas por meio de eletroforese (SDS-PAGE. A observação densitométrica dos perfis eletroforéticos permitiu avaliar as concentrações relativas de 16 frações protéicas que foram usadas como variáveis para a estimativa de funções discriminantes de Fisher. Diferenças significantes foram encontradas entre as frações protéicas dos grupos brasileiros e japoneses, assim como entre os genótipos melhorados e não melhorados. O polimorfismo protéico detectável eletroforetica-mente nos grãos de arroz pode indicar a origem geográfica e o nível de melhoramento dos cultivares.

    We show how spatial variability in channel bed morphology affects the hydraulic characteristics of river reaches available to Atlantic salmon parr (Salmo salar) under different flow conditions in an upland stream. The study stream, the Girnock Burn, is a long-term monitoring site in the Scottish Highlands. Six site characterised by different bed geometry and morphology were investigated. Detailed site bathymetries were collected and combined with discharge time series in a 2D hydraulic model to obtain spatially distributed depth-averaged velocities under different flow conditions. Available habitat (AH) was estimated for each site. Stream discharge was used according to the critical displacement velocity (CDV) approach. CDV defines a velocity threshold above which salmon parr are not able to hold station and effective feeding opportunities or habitat utilization are reduced, depending on fish size and water temperature. An average value of the relative available habitat () for the most significant period for parr growth - April to May - was used for inter-site comparison and to analyse temporal variations over 40years. Results show that some sites are more able than others to maintain zones where salmon parr can forage unimpeded by high flow velocities under both wet and dry conditions. With lower flow velocities, dry years offer higher values of than wet years. Even though can change considerably across the sites as stream flow changes, the directions of change are consistent. Relative available habitat (RAH) shows a strong relationship with discharge per unit width, whilst channel slope and bed roughness either do not have relevant impact or compensate each other. The results show that significant parr habitat was available at all sites across all flows during this critical growth period, suggesting that hydrological variability is not a factor limiting growth in the Girnock.

    In this study, radon and radon daughter concentrations were measured in specific underground workplaces: in vine cellars, showcaves and caves for speleotherapeutic treatment of patients. These workplaces are considered to be affected by high radon concentrations, the workers in some cases can be exposed to radiation from radon and short-lived daughters at levels, comparable to those of other underground workplaces such as uranium mines. The aim of the study was to reveal the variation of the radon and radon progeny concentration, and to estimate the dose to the workers and visitors of these workplaces from the radon daughters. Seasonal variations of radon concentrations have been found in most of the caves investigated. The magnitude of the variation depends on the degree of isolation of the cave cavity from the outdoor atmosphere. The radon concentrations of the vine cellars were much lower than that of the caves. Because of the produced carbon dioxide gas in the process of sugar fermentation even the very old cellars are constructed well ventilated, consequently radon can not be accumulated in this underground cavities. From the measured radon and progeny concentrations cumulative potential alpha energy exposure, bronchial dose, and effective dose values were calculated for the staff, patients and visitors. The effective dose values for the cave personnel do not exceed the 10 mSv year -1 upper bound of the action level recommended for workplaces and even much lower for workers of cellars. The doses for visitors and patients were one or two magnitudes lower than that of the workers. (author)

    Inorganic arsenic can get easily through the placenta however there are very few human data on congenital anomalies related to arsenic exposure. Objective of our study was to explore the associations between arsenic content of drinking water and prevalence of some congenital anomalies. Four anomalies reported to the Hungarian Congenital Anomalies Registry between 1987 and 2003 were chosen to be analysed in relation to arsenic exposure: congenital anomalies of the circulatory system (n=9734) were considered as cases, while Down syndrome, club foot and multiple congenital malformations were used as controls (n=5880). Arsenic exposure of the mothers during pregnancy was estimated by using archive measurement data for each year and for each settlement where the mothers lived. Analysis of the associations between the prevalence of congenital heart anomalies and arsenic exposure during pregnancy was performed by logistic regression. The child's gender and age of the mother were adjusted for. The associations were evaluated by using the present EU health limit value of 10.0 μg/L arsenic concentration as a cut-off point. Regular consumption of drinking water with arsenic concentration above 10 μg/L during pregnancy was associated with an increased risk of congenital heart anomalies in general (adjusted OR=1.41; 95% C.I.: 1.28-1.56), and especially that of ductus Botalli persistens (adjusted OR=1.81, 95%C.I.: 1.54-2.11) and atrial septal defect (adjusted OR=1.79; 95%C.I.: 1.59-2.01). The presented results showed an increased risk of congenital heart anomalies among infants whose mothers were exposed to drinking water with arsenic content above 10 μg/L during pregnancy. Further studies of possible similar effects of concentrations below 10 μg/L are warranted. Copyright © 2014 Elsevier GmbH. All rights reserved.

  17. The role of tolerant genotypes and plant nutrients in the management of acid soil infertility in upland rice

    As in other parts of the humid tropics, acid-related problems are the major constraint to crop production on low-activity clay soils in the humid and sub-humid zones of West Africa. The upland ecosystem of West Africa is very important to rice production. About 70% of upland rice is grown in the humid zone of the sub-region. To increase and stabilize rice productivity of the acid uplands at reasonable levels, a strategy is needed that integrates the use of tolerant cultivars with soil and plant-nutrient management. Research conducted on Alfisols and Ultisols of the humid-forest and savannah zones in West Africa showed that upland rice is a robust crop, possessing a wide range of tolerance to acid-soil conditions. Recent research at WARDA showed also that acid-soil tolerance can be enhanced through interspecific Oryza sativa x O. glaberrima progenies, which not only possess increased tolerance of acid-soil conditions, but also have superior overall adaptability to diverse upland environments in the sub-region. Our research on the diagnosis of acid-soil infertility problems on the Ultisols and Alfisols of the humid savannah and forest zones indicates that P deficiency is the most important nutrient disorder for upland rice. In the forest zone, response to N depended on the application of P. In the savannah and forest-savannah transition zones, N deficiency was more important than P deficiency. Among other plant nutrients, the application of Ca and Mg (as plant nutrients) did not appear initially to improve the performance of acid-tolerant upland rice cultivars. The results from a long-term study on an Ultisol with four acid-tolerant rice cultivars, revealed that they differed in agronomic and physiological P efficiencies, and the efficiencies were higher at lower rates of P. The amounts of total P removed in three successive crops were similar for all four cultivars although P-harvest index was 10 to 12% higher in the P-efficient than the inefficient cultivars. The

    The monthly distribution of pregnancy outcomes such as induced abortions, spontaneous abortions, stillbirths, newborns with birth weight under 2500 g, isolated congenital anomalies, identified multiple congenital anomaly syndromes including fetal radiation syndrome, and unidentified multiple congenital anomalies was evaluated in Hungary after the Chernobyl accident until Apr 1987. Only a somewhat higher rate of newborns with birth weight under 2500 g in May and June, 1986 was detected. It may have been due to premature labour caused by anxiety. (author) 15 refs.; 2 tabs

    The main objective of the DOSoReMI.hu (Digital, Optimized, Soil Related Maps and Information in Hungary) project is to significantly extend the potential, how demands on spatial soil related information could be satisfied in Hungary. Although a great amount of soil information is available due to former mappings and surveys, there are more and more frequently emerging discrepancies between the available and the expected data. The gaps are planned to be filled with optimized DSM products heavily based on legacy soil data. Delineation of Areas with Excellent Productivity in the framework of the National Regional Development Plan or delimitation of Areas with Natural Constraints in Hungary according to the common European biophysical criteria are primary issues in national level spatial planning. Impact assessment of the forecasted climate change and the analysis of the possibilities of the adaptation in the agriculture and forestry can be supported by scenario based land management modelling, whose results can be also incorporated in spatial planning. All these challenges require adequate, preferably timely and spatially detailed knowledge of the soil cover. For the satisfaction of these demands the soil conditions of Hungary have been digitally mapped based on the most detailed, available recent and legacy soil data, applying proper DSM techniques. Various soil related information were mapped in three distinct approaches: (i) basic soil properties determining agri-environmental conditions (e.g.: soil type according to the Hungarian genetic classification, rootable depth, sand, silt and clay content by soil layers, pH, OM and carbonate content for the plough layer); (ii) biophysical criteria of natural handicaps (e.g.: poor drainage, unfavourable texture and stoniness, shallow rooting depth, poor chemical properties and soil moisture balance) defined by common European system and (iii) agro-meteorologically modelled yield values for different crops, meteorological

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

    After a thourough development phase, a new system of health financing was introduced in Hungary in 1993. One of the cornerstones of the system was the financing of acute hospital care through Diagnosis-Related Groups (DRGs). This method was part of a comprehensive healthcare model, elaborated and published around 1990 by experts of Gyógyinfok, a public institute. The health financing system that was finally introduced reflcted in large part this theoretical model, while the current Hungarian system differs from it in some important respects. The objective of this article is to identify these points of divergence.

    Stable isotope and radiocarbon data of groundwater stored in Quaternary aquifers in North-Eastern Hungary can not be explained by climatic changes alone. More than two hundred δD, δ 18 O and radiocarbon ages of waters from 79 wells show that the recharge are changed during the time of upper pleniglacial and late glacial. Groundwaters of the studied are can be divided into three categories, which can explain their origin. The data are consistent with geomorphological results giving isotope evidence of hydrology for a geodynamical event during the mentioned periods. (R.P.) 3 refs.; 2 figs

    In Hungary, during the past decade five distinct regions have been chosen to find possible explanations of the uncommonly high radon background radiation values. The main aim of the research is to study U- and Th-bearing minerals in petrographic and geochemical characters. Besides the microscopic techniques, whole rock and in situ geochemical analytical methods were applied to determine the bulk U and Th content of the studied geological samples. We assume that some of the radon measured is related to the U and Th contents of the samples. (authors)

    Full Text Available We measure the amount of central bank seigniorage generated in three economies in transition and inquire to what extent seigniorage ultimately accrues to the government. We relate our findings to the institutional environment of the three countries. We find that, in parallel to the process of disinflation, seigniorage has declined substantially in the 1990s in all three countries under consideration pointing to more monetary discipline and a strengthening of central bank independence. Only in Hungary seigniorage benefited the government to a significant amount. We interpret this as being the consequence of past policies, rather than an obstacle to further disinflation.

    The ratio of Danube water/infiltrated precipitation has been determined using stable oxygen isotope data on four parts of the protection area of the bank filtered water works supplying drinking water for Budapest, Hungary. These ratios comparing to those calculated by hydraulic modeling rarely match each other. The Danube water transit time calculated fro few wells by isotopic data are usually shorter than those determined by hydraulic modeling. The relation between the δ 18 O values and the nitrate chloride and sulfate pollutants shows that the source of the pollutants is on the island area (sewage water, agricultural activity and salt used for de-icing asphalt roads).

  11. The Agency's technical co-operation programme with Hungary 1983-1993 country programme summaries

    International Nuclear Information System (INIS)

    1993-01-01

    This report contains a review of the Agency's technical co-operation activities in Hungary carried out during 1983-1993. In terms of coverage and analytical depth, country programmes summaries stand somewhere midway between in-depth country programme evaluations and individual project evaluations. They attempt to provide a comprehensive, descriptive picture of the Agency's co-operation with a Member State in a manner that will be particularly useful for programming decisions. The attempt is very much to describe - largely through statistical data - not to provide independent analysis and evaluation

    Measurements of aerosol activity from the Chernobyl reactor accident are reported. The concentrations of 14 radionuclides were obtained by gamma spectrometry for the period 30 April - 9 May, 1986. Gross beta measurements were also done through 11 August 1986 of which 137 Cs activity concentrations were derived. 90 Sr activity concentrations were also determined for selected aerosol samples using nondestructive procedure. The time course of contamination observed in Debrecen (Hungary) is discussed in terms of trajectory analysis. Isotopic ratios are also used to trace down routes of contamined air. In addition, such ratios are also used to characterize the status of the damaged reactor at different times. (author) 15 refs.; 2 figs

    Laíse Ferreira de Araújo

    Full Text Available The continuous development and evaluation of new genotypes through crop breeding is essential in order to obtain new cultivars. The objective of this work was to evaluate the genetic divergences between cultivars of upland cotton (Gossypium hirsutum L. using the agronomic and technological characteristics of the fibre, in order to select superior parent plants. The experiment was set up during 2010 at the Federal University of Ceará in Fortaleza, Ceará, Brazil. Eleven cultivars of upland cotton were used in an experimental design of randomised blocks with three replications. In order to evaluate the genetic diversity among cultivars, the generalised Mahalanobis distance matrix was calculated, with cluster analysis then being applied, employing various methods: single linkage, Ward, complete linkage, median, average linkage within a cluster and average linkage between clusters. Genetic variability exists among the evaluated genotypes. The most consistant clustering method was that employing average linkage between clusters. Among the characteristics assessed, mean boll weight presented the highest contribution to genetic diversity, followed by elongation at rupture. Employing the method of mean linkage between clusters, the cultivars with greater genetic divergence were BRS Acacia and LD Frego; those of greater similarity were BRS Itaúba and BRS Araripe.

    In the tropics, shifting cultivation has long been attributed to large scale forest degradation, and remains a major source of uncertainty in forest carbon accounting. In the Philippines, shifting cultivation, locally known as kaingin, is a major land-use in upland areas. We measured the distribution and recovery of aboveground biomass carbon along a fallow gradient in post-kaingin secondary forests in an upland area in the Philippines. We found significantly higher carbon in the aboveground total biomass and living woody biomass in old-growth forest, while coarse dead wood biomass carbon was higher in the new fallow sites. For young through to the oldest fallow secondary forests, there was a progressive recovery of biomass carbon evident. Multivariate analysis indicates patch size as an influential factor in explaining the variation in biomass carbon recovery in secondary forests after shifting cultivation. Our study indicates secondary forests after shifting cultivation are substantial carbon sinks and that this capacity to store carbon increases with abandonment age. Large trees contribute most to aboveground biomass. A better understanding of the relative contribution of different biomass sources in aboveground total forest biomass, however, is necessary to fully capture the value of such landscapes from forest management, restoration and conservation perspectives.

    Rocky Flats Environmental Technology Site (Site) is located on the Colorado Piedmont east of the Front Range between Boulder and Golden. At an elevation of approximately 6,000 feet, the Site contains a unique ecotonal mixture of mountain and prairie plant species, resulting from the topography and close proximity to the mountain front. The Buffer Zone surrounding the Industrial Area is one of the largest remaining undeveloped areas of its kind along the Colorado Piedmont. A number of plant communities at the Site have been identified as increasingly rare and unique by Site ecologists and the Colorado Natural Heritage Program (CNHP). These include the xeric tallgrass prairie, tall upland shrubland, wetlands, and Great Plains riparian woodland communities. Many of these communities support populations of increasingly rare animals as well, including the Preble's meadow jumping mouse, grasshopper sparrow, loggerhead shrike, Merriam's shrew, black crowned night heron, and Hops blue and Argos skipper butterflies. One of the more interesting and important plant communities at the Site is the tall upland shrubland community. It has been generally overlooked by previous Site ecological studies, probably due to its relatively small size; only 34 acres total. Although mentioned in a plant community ordination study conducted by Clark et al. and also in the Site baseline ecological study, few data were available on this plant community before the present study

  18. The Politics of PVC: Technology and Institutions in Upland Water Management in Northern Thailand

    2009-06-01

    Full Text Available Conflict over water has grown in the mountainous areas of Thailand since the replacement of opium with alternative crops. PVC-sprinkler irrigation has enabled dry-season expansion of these cash crops on sloping lands, intensifying demand for water when it is most scarce. The technology and institutions that form the backbone of these irrigation systems have evolved simultaneously in a process of adaptive governance, in which local farmers draw on local social resources to balance competition and cooperation. Common conceptions of upstream – downstream conflict, pitting Thai against ethnic minorities in a struggle for resources, dominate the discourse of watersheds in Thailand. Upland water users themselves are diverse and their resource management systems are dynamic, even if they are not recognised as legitimate users of water. Understanding how upland communities create local systems of resource governance through dry-season irrigation is highly relevant for governance at higher levels, such as in the efforts to establish watershed networks and river basin organisations.

    Full Text Available The effects of biochar and nitrogen application on yields of upland rice and cowpea and on soil fertility were determined in a greenhouse in Macaíba, RN, Brazil. The trial consisted of the succession of two crops in a completely randomized design and a factorial scheme, with four replicates. Initially, four doses of biochar and four doses of nitrogen were tested for cultivation of rice. Subsequently, four doses of biochar and two doses of nitrogen were tested in half of the pots maintained for planting cowpea. Soil was sampled after rice harvest for half of the pots and at end of the trial for the remaining pots. We evaluated the following parameters: mass of hundred grains of rice, dry shoot mass, panicle number, number of filled spikelets and of empty spikelets, and grain production. Determinations for cowpea were: pod number per pot, grain number per pod, and grain production per pot. Measured soil parameters were: pH, contents of organic carbon, P, K, Ca, Mg, Na, cation exchange capacity, and exchangeable sodium percentage. Biochar addition did not influence yield components of upland rice and cowpea, but resulted in increased soil N retention, which influenced rice dry shoot mass, spikelets sterility, panicle number, and grain mass. Biochar also promoted increased soil pH, potassium content, and exchangeable sodium percentage and decreased calcium and magnesium concentrations.

    Mt. Gongga area in southwest China was impacted by Hg emissions from industrial activities and coal combustion, and annual means of atmospheric TGM and PHg concentrations at a regional background station were 3.98 ng m -3 and 30.7 pg m -3 , respectively. This work presents a mass balance study of Hg in an upland forest in this area. Atmospheric deposition was highly elevated in the study area, with the annual mean THg deposition flux of 92.5 μg m -2 yr -1 . Total deposition was dominated by dry deposition (71.8%), and wet deposition accounted for the remaining 28.2%. Forest was a large pool of atmospheric Hg, and nearly 76% of the atmospheric input was stored in forest soil. Volatilization and stream outflow were identified as the two major pathways for THg losses from the forest, which yielded mean output fluxes of 14.0 and 8.6 μg m -2 yr -1 , respectively. - Upland forest ecosystem is a great sink of atmospheric mercury in southwest China.

    IPCC projections show that climate warming will be particularly high in northern high-latitude regions, which has profound ecohydrological implications: a small rise of temperature may result in lower water availability in summer due to less rainfall and more evapotranspiration, increase flooding risks by accelerating melting rates in spring, and more rain rather than snow in winter, etc. These impacts will affect vegetation communities by altering timing of the spring "green-up" and fall "senescence". Change in vegetation water use will feedback to atmospheric and hydrological cycles. Here, we report results from the PLATO "Plant-water interlinkages in northern uplands - mediation of climate change?" project where we investigate water uptake by plants and consequent water availability in northern regions along a cross-regional climate gradient to understand future responses to change in high-latitude uplands. Six sites in Sweden (Krycklan), Canada (Wolf Creek; Baker Creek; Dorset), Scotland (Girnock) and the USA (Dry Creek) span moisture and energy gradients found at high-latitudes. We are presenting preliminary results of vegetation phenology changes from 2000 to 2014 by analysing remote sensing vegetation indices. The relationship between vegetation phenology and climatic drivers (temperature and precipitation) is also investigated.

    In order to investigate the soil-to-plant transfer factor (TF) of {sup 99}Tc for Korean major upland crops (soybean, radish and Chinese cabbage), pot experiments were performed in a greenhouse. Soils were collected from four upland fields (two for soybean and two for radish and Chinese cabbage) around Gyeongju radioactive-waste disposal site. Three to four weeks before sowing, dried soils were mixed with a {sup 99}Tc solution and the mixtures were put into pots and irrigated. TF values were expressed as the ratios of the {sup 99}Tc concentrations in plants (Bq kg{sup -1}-dry or fresh) to those in soils (Bq kg{sup -1}-dry). There was no great difference in the TF value between soils. The TF values for soybean seeds were extremely lower than those for the straws, indicating a very low mobility of {sup 99}Tc to seeds. As representative TF values of{sup 99}Tc,1.8 X 10{sup -1}, 1.2 X 10{sup 1}, 3.2 X 10{sup 2} and 1.3 X 10{sup 2} (for dry plants), arithmetic means for two soils, were proposed for soybean seeds, radish roots, radish leaves and Chinese cabbage leaves, respectively. In the case of the vegetables, proposals for fresh plants were also made. The proposed values are not sufficiently representative so successive updates are needed.

    Full Text Available ABSTRACT The study was carried out in Selvíria-MS, in the 2011/12 and 2012/13 agricultural years, aiming to evaluate the efficiency of Azospirillum brasilense in nitrogen fixation in upland rice, as a function of doses and application methods of the inoculant containing this diazotrophic bacterium. The experimental design was randomized blocks, arranged in a 4 x 4 factorial scheme, with 4 doses of inoculant (control without inoculation, 100, 200 and 300 mL of the commercial product ha-1 and 4 application methods (seed inoculation, application in the sowing furrow, soil spraying after sowing, and foliar spraying at the beginning of plant tillering, with 4 replicates. During the experiment, the agronomic characteristics, production components and yield of the rice crop were evaluated. It was concluded that the inoculant containing Azospirillum brasilense promotes increase (19% in the yield of upland rice under sprinkler irrigation when used at the dose of 200 mL ha-1, regardless of the application methods.

    Carbon and water cycling of forests contribute significantly to the Earth's overall biogeochemical cycling and may be affected by disturbance and climate change. As a larger body of research becomes available about leaf-level, ecosystem and regional scale effects of disturbances on forest ecosystems, a more mechanistic understanding is developing which can improve modeling efforts. Here, we summarize some of the major effects of physical and biogenic disturbances, such as drought, prescribed fire, and insect defoliation, on leaf and ecosystem-scale physiological responses as well as impacts on carbon and water cycling in an Atlantic Coastal Plain upland oak/pine and upland pine forest. During drought, stomatal conductance and canopy stomatal conductance were reduced, however, defoliation increased conductance on both leaf-level and canopy scale. Furthermore, after prescribed fire, leaf-level stomatal conductance was unchanged for pines but decreased for oaks, while canopy stomatal conductance decreased temporarily, but then rebounded the following growing season, thus exhibiting transient responses. This study suggests that forest response to disturbance varies from the leaf to ecosystem level as well as species level and thus, these differential responses interplay to determine the fate of forest structure and functioning post disturbance.

    Research on the effects of wetland restoration on reptiles and amphibians is becoming more common, but almost all of these studies have observed the colonization of recently disturbed habitats that were completely dry at the time of restoration. In a similar manner, investigations herpetofaunal responses to forest management have focused on clearcuts, and less intensive stand manipulations are not as well studied. To evaluate community and population responses of reptiles and amphibians to hydrology restoration and canopy removal in the interior of previously degraded Carolina bays, I monitored herpetofauna in the uplands adjacent to six historically degraded Carolina bays at the Savannah River Site (SRS) in South Carolina for four years after restoration. To evaluate the effects of forest thinning on upland herpetofauna, forests were thinned in the margins of three of these bays. I used repeated measures ANOVA to compare species richness and diversity and the abundance of selected species and guilds between these bays and with those at three reference bays that were not historically drained and three control bays that remained degraded. I also used Non-metric Multidimensional Scaling (NMDS) to look for community-level patterns based treatments.

    A review of urban change in Hungary in the twentieth century is presented. Both the traditional approach to studying urban change, involving changes in the percentage of those residing in urban areas, and the newly developed approach, focusing on regional aspects of urbanization, are used in the analysis. "In sharp contrast to most European countries Hungary is shown to evidence continued centralization of urban development, but the recent experience of Budapest and other indicators are said to portend future decentralization."

    Seasonal dynamics and reproductive phenological parameters of four Carabus species (C. convexus, C. coriaceus, C. germarii and C. hortensis) common in Hungary were studied by pitfall trapping and dissection. Beetles were collected in an abandoned apple orchard and in the bordering oak forest near...... Budapest (Central Hungary), in 1988–1991. The sex ratio was male-dominated, but this was significant only for C. coriaceus. The catch of C. germarii adults showed relatively short activity period with unimodal curve, but activity was longer and bimodal for the other three species. Adults of C. germarii...

    2010-01-01

    Full Text Available Drawing on the field research conducted in the Serbian community in Szigetcsép, Hungary, the paper examines interlocutors’ oral discourse on interethnic marriages. Until the Second World War, the Serbs in Hungary, rural communities in particular, mainly practised endogamy. In the post-war era, however, they tended to be among the minority groups with the highest rate of exogamic marriages. Conse­quently, the interviewees established discourse links between “interethnic marriages”, “loss of native language” and “fear of identity loss”. The analytical focus is on the interlocutors’ internal dialogism between the authoritative word of the ancestors and autobiographical assertions.

    During the period starting around Hungary's accession to the European Union in 2004 and finishing before the financial crisis in 2008, Hungary became the member of the European Union, had three governments, prepared its Sustainable Development Strategy, established its National Council for Sustainable Development, and created the position of Parliamentary Commissioner for Future Generations. This article analysis sustainability discourse in the Hungarian electronic media by state and government leaders during this period, and reviews three public opinion polls about sustainability awareness taken in 2006 and 2008 to demonstrate if any concurrent change of sustainability attitudes can be traced in the Hungarian population

    Uranium ore mining and milling have been terminated in the Mecsek Mountains (southwest Hungary) in 1997. Mine tailings ponds are located between two important water bases, which are resources of the drinking water of the city of Pecs and the neighbouring villages. The average U concentration of the tailings material is 71.73 μg/g, but it is inhomogeneous. Some microscopic particles contain orders of magnitude more U than the rest of the tailings material. Other potentially toxic elements are As and Pb of which chemical state is important to estimate mobility, because in mobile form they can risk the water basis and the public health. Individual U-rich particles were selected with solid state nuclear track detector (SSNTD) and after localisation the particles were investigated by synchrotron radiation based microanalytical techniques. The distribution of elements over the particles was studied by micro beam X-ray fluorescence (μ-XRF) and the oxidation state of uranium and arsenic was determined by micro X-ray absorption near edge structure (μ-XANES) spectroscopy. Some of the measured U-rich particles were chosen for studying the heterogeneity with μ-XRF tomography. Arsenic was present mainly in As(V) and uranium in U(VI) form in the original uranium ore particles, but in the mine tailings samples uranium was present mainly in the less mobile U(IV) form. Correlation was found between the oxidation state of As and U in the same analyzed particles. These results suggest that dissolution of uranium is not expected in short term period. (authors)

    Tritium occurs in nature in trace amounts, but its concentration is changing due to natural and artificial sources. Studies focusing on natural tritium have to take into account the effect of artificial sources. Also, the impact of tritium is an important issue in environmental protection, e.g. in connection with the emissions from nuclear power plants. The present work focuses on the rain washout of tritium emitted from the Paks nuclear power plant in Hungary. Rainwater collectors were placed around the plant and after a period of precipitation, rainwater was collected and analysed for tritium content. Samples were analysed using low-level liquid scintillation counting, with some also subject to the more accurate 3 He ingrowth method. The results clearly show the trace of the tritium plume emitted from the plant; however, values are only about one order of magnitude higher than environmental background levels. A washout model was devised to estimate the distribution of tritium around the plant. The model gives slightly higher concentrations than those measured in the field, but in general the agreement is satisfactory. The modelled values demonstrate that the effect of the plant on rainwater tritium levels is negligible over a distance of some kilometres. - Research highlights: →The rainwater around a nuclear power plant was collected with a special rainwater collector →The rainwater after a rain event was analysed for tritium with LSC and with the helium ingrowth method. →The trace of the tritium plume is clearly detectable in the rainwater. →The agreement between a reversible washout model and experimental data is satisfactory. →According to the model the tritium plume is hardly detectable over some kilometers from the plant

    Complete text of publication follows. Aerosol pollution represents significant health hazard in urban environments. Despite the fact that Debrecen has not a much stressed environment the city is highly exposed to aerosol pollution. In order to evaluate the impact of aerosol particles on health, the knowledge of the particle size distribution, chemical composition, sources, and their change in time and space is needed. This work presents a source apportionment study of fine (particles with aerodynamic diameter less than 2.5 μm) and coarse (particles with aerodynamic diameter between 2.5 and 10 μm) particulate matter in Debrecen by following the evolution of the elemental components with hourly time resolution. The variation of the elemental concentrations, their periodicity, correlation with other elements and meteorological parameters were studied on samples collected in different seasons. Aerosol sources were determined using the positive matrix factorization (PMF) method. Aerosol samples were collected in the garden of the ATOMKI with a 2-stage sequential streaker sampler manufactured by PIXE International, which collected the fine and coarse fraction separately with few hours' time resolution. Between October 2007 and January 2009 five 10-days long sampling campaigns were carried out. The elemental composition was determined by Particle Induced X-ray emission (PIXE) for Z ≥ 13, and the elemental carbon (BC) content was estimated with a smoke stain reflectometer. Source apportionment was carried out with the PMF receptor model developed for aerosol source characterization, provided by US EPA. Mass of species apportioned to factor, percentage of species apportioned to factors and average factor contributions of the campaigns, of working days and weekends and within the days were calculated. The PMF analysis resulted seven factors in the fine and seven factors in the coarse mode. The main sources of atmospheric aerosol in the city of Debrecen were traffic

    The species richness and species composition of Coleoptera assemblages were investigated in deciduous tree canopies in Hungary. Apple and pear orchards were investigated in Nagykovácsi, Kecskemét and Sárospatak in 1990-94, and limes and maples in Keszthely in 1999-2002. Faunistic results and conclusions of these investigations were published elsewhere. Examination of the fauna of parks, avenues and other planted urban plant stocks has only begun to occupy researchers in the last decade in Hungary. The proportion of leaf-beetle species in the material gathered on maples and limes ranged between 17.0 and 21.3 per cent. The commonest leaf-beetle specimens collected in the lime canopy were Aphthona euphorbiae, Chaetocnema tibialis, Longitarsus lycopi, L. pellucidus, L. pratensis and L. succineus. The commonest on maple were Aphthona euphorbiae, Chaetocnema concinna, C. tibialis, Longitarsus lycopi, L. pellucidus, L. succineus, Phyllotreta cruciferae and P. vittula. This study presents the details on the composition of the chrysomelid communities that was compared by metric ordination using the Syntax 5.1 program.

    This paper examines two community projects implemented by the United Nations Development Programme (UNDP). The first, Promoting Access to Energy Services to Foster Integration and Human Development for Disadvantaged Communities in Hungary and Slovakia with a Special Focus on the Roma, built on regional development work with isolated communities without reliable access to heat and electricity. The second, Energy Efficiency in Housing in Bosnia and Herzegovina (BiH), focused on a network of communities where rebuilding was underway following the Balkans conflict. While the projects took place in different environments, both shared common approaches. First, they focused on community energy planning in areas where infrastructure was severely deficient. Planning was designed so that current investments in building stock would not have to be retrofitted later for efficiency. Second, they linked energy agencies and NGOs with institutions outside of the energy/environment community, such as the National Minority Self Government in Hungary and the Ministry of Refugees in BiH . The projects thus leveraged funds and expertise from new sources while raising awareness of sustainable energy issues in organizations already funding infrastructure.While time and funding were limited by the terms of the grants, both projects established a foundation of information, planning, and partnerships. Both projects included baseline energy studies, training workshops, and practical guides for local leaders. In addition, there were tangible community benefits in education (reliable heat supply for a new kindergarten), jobs creation (wood-chipping in a municipal forest), and business development (contracts for efficient construction)

    The question of electronic solutions in public health care has become a contemporary issue at the European Union level since the action plan of the Commission on the e-health developments of the period between 2012 and 2020 has been published. In Hungary this issue has been placed into the centre of attention after a draft on modifications of regulations in health-care has been released for public discourse, which - if accepted - would lay down the basics of an electronic heath-service system. The aim of this paper is to review the basic features of e-health solutions in Hungary and the European Union with the help of the most important pieces of legislation, documents of the European Union institutions and sources from secondary literature. When examining the definition of the basic goals and instruments of the development, differences between the European Union and national approaches can be detected. Examination of recent developmental programs and existing models seem to reveal difficulties in creating interoperability and financing such projects. Finally, the review is completed by the aspects of jurisdiction and fundamental rights. It is concluded that these issues are mandatory to delineate the legislative, economic and technological framework for the development of the e-health systems.

  17. Educating Apostles of the Homeland: Tourism and "Honismeret" in Interwar Hungary

    Full Text Available Promoters of domestic tourism in Hungary between the world wars laid blame for poor business at the feet of many causes. But their loudest and most persistent accusation was that Hungarians did not travel their homeland because they did not properly “know it.” At the same time, geographers, educators, and politicians made the nearly identical claim that Hungarians were lacking in honismeret, or “knowledge of one’s homeland,” and needed to banish their ignorance if they were to truly and adequately love their country. This article explores one confluence of these two streams. Between 1934 and 1942, metropolitan authorities sponsored an ambitious educational program, the School Excursion Trains of the Capital City of Budapest [Budapest Székesfőváros Iskolai Kirándulóvonatai], which aimed to improve the honismeret of high school students by giving them first-hand experience of dozens of Hungarian cities and regions. Through a close analysis of the 31-volume series of guidebooks produced for the benefit of the Excursion Train passengers, this article argues that the fundamental goal of the program was to transform Hungary from an abstract territorial space into a set of concrete places to which students could feel personally attached, and therefore better “know.”

    Full Text Available The aim of the research was to define the size of the Hungarian LOHAS (Lifestyle of Health and Sustainability consumer group by analyzing its lifestyle based on sustainable values. To achieve this goal, a representative questionnaire-based survey was carried out involving 1000 individuals in Hungary. During the value-orientated research, 25 lifestyle statements were drawn up. According to the results, five value-based segments could be distinguished. The largest cluster, the young trend followers group, reflects the characteristics of the LOHAS consumers’ lifestyle to the greatest extent. However, this segment cannot entirely be regarded as a consumer group devoted to LOHAS values, which is why a further segmentation of this group was necessary. As a result of this further segmentation, the third sub-cluster, which emphasizes the ethical (competence statements the most, can be identified with the LOHAS consumer group, which makes up 8.7% of the Hungarian population. Further research is necessary to find out whether the situation regarding value orientation in Hungary is similar to that in other Eastern European countries whose social and cultural backgrounds are very similar. Revealing the values of the Lifestyle of Health and Sustainability segment contributes to the extension of the literature.

    The study of atmospheric aerosols originating from natural and anthropogenic processes is of basic importance for a detailed understanding of the physics and chemistry of the atmosphere. Particle Induced X-ray Emission (PIXE) technique has been used by the authors for studying regularly the elemental composition of rural, suburban, and urban aerosols collected at six sampling sites in Hungary. Observed data presented in terms of concentrations and regional signature values and evaluated wind sector partition and in transport modelling revealed the natural/anthropogenic contribution to the moderate air pollution here. Dry deposition velocities have been deduced for elements V, Cr, Mn, Co, Ni, Cu, Zn, Cd, and Pb. Model calculations based on annual emission data and observed elemental concentrations resulted in total dry and wet deposition masses of the above elements to the territory of the country. At the same time, deduced budget data for the emission and deposition of the constituents indicated whether the country represents a net source or a sink for the above mentioned elements in the regional aerosol transport between neighbouring countries. Evidences have been found for intrusion events of Saharan aerosol to the atmosphere of Hungary. Part of the data collected recently will be evaluated in the frame-work of an international co-ordinated research programme. (author)

  20. Memoralization of the Holocaust in the Polish film Aftermath and in contemporary Hungary

    2014-04-01

    Full Text Available In contemporary Eastern Europe, after the policy of forced forgetting under communism, a memory bomb exploded in 1989. Society was said to have broken out from under the red carpet under which everything had been swept. Suddenly, everything was rendered visible. In the village described in Aftermath, even the red carpet was not really needed: the crimes committed had already been covered up, and in the absence of any real contact with the outside world, the villagers had been able to use communist laws to bury their secret even deeper. Evidently, the situation in Hungary, home to Central Europe’s largest Jewish survivor community, is even more complicated. While silence and forgetting meant, for many, abandoning one’s Jewish identity, among some families and groups of friends the discussion of past events was a means of establishing identity. In informal salon-style gatherings, people told family stories, and this became an important way of establishing group cohesion. Personal narration gave credibility to the historical events: by telling the stories, people made them true. Linked with this were efforts to improve the emotional and intellectual well-being of the surviving mourners, combining the commandment of nichumaveilim with memory policy. This commandment connects the story of the brothers in Aftermath with the battles over the politics of memory in Hungary.

    Full Text Available This article aims to provide an overview of the working conditions of high-skilled employees in Hungary, by resorting to comparisons with the other Central and Eastern European countries, based on research carried out by the author during a three-month placement (August 1st-October 31st 2011 at the Institute of Sociology of the Hungarian Academy of Sciences. This work combines several sources and methods for gathering information: theoretical documentation, secondary analysis of data, in-depth interviews with some experts in the field. The study results indicate the presence, for the knowledge workers in Hungary, of some common problems of this category of employees in all former communist countries, such as number of working hours per week more than EU average, low rate of participation in training, problems health such as stress, depression, heart disease etc., employees' complaints related to overworking associated with low wages in the public sector and with rigid hierarchy, lack of work-life balance, standards imposed by the parent company etc. in some multinational firms; cases of good practice appear at the micro level, mainly in Scandinavian capital firms or in companies in the IT sector.

    Health technology assessment (HTA) is not simply a mechanistic technical exercise as it takes place within a specific institutional context. Yet, we know little about how this context influences the operation of HTA and its ability to influence policy and practice. We seek to demonstrate the importance of considering institutional context, using a case study of Hungary, a country that has pioneered HTA in Central and Eastern Europe. We conducted 26 in-depth, semi-structured interviews with public- and private-sector stakeholders. We found that while the HTA Department, the Hungarian HTA organisation, fulfilled its formal role envisaged in the legislation, its potential for supporting evidence-based decision-making was not fully realised given the low levels of transparency and stakeholder engagement. Further, the Department's practical influence throughout the reimbursement process was perceived as being constrained by the payer and policy-makers, as well as its own limited organisational capacity. There was also scepticism as to whether the current operational form of the HTA process delivered 'good value for money'. Nevertheless, it still had a positive impact on the development of a broader institutional HTA infrastructure in Hungary. Our findings highlight the importance of considering institutional context in analysing the HTA function within health systems.

    Full Text Available This paper focuses on a complex question from the perspective of the hotel industry. It tries to draw attention to the importance of hotels, enhancing it on the basis of the tourism destination competitiveness models and introducing the role and place of the hotel industry in the most important models. The hotel industry research evaluates the most important tourism destinations of Hungary on the micro-regional level that justifies the importance and contribution of the hotels and accommodations to competitiveness and success of tourism destinations with exact results. As a result of the research, the micro-regional destinations can be ranged within three groups in Hungary. In the first group of the most developed and most competitive tourism destinations, the hotel industry plays a very important role. In these regions, the hotel industry has a significant effect not only on competitiveness of tourism but also on general development of the regions. In the second group, which can be still called tourism destination, tourism and the hotel industry both play a significant role, but only the competitiveness of tourism can be considered good, the effects of the tourism on general development of the region can be proved only to a lesser extent. In the third group, the effects of tourism and the hotel industry can only be experienced to a lesser extent. The majority of these regions are not considered to be attractive tourism destinations for tourists any more.

    Full Text Available In 2014, in cooperation with the Action and Protection Foundation, Kristóf Bodó, a practicing lawyer, and I had the opportunity to teach a course titled The Background and Social Consequences of Hate Crimes at the University of Public Service for students in the Faculty of Law Enforcement, Public Administration, and Military Sciences. The opportunity was exceptional indeed, since teaching about hate crimes in Hungary is rarely present, especially not in an institutional environment. However, this would be generally important, especially in university programmes where students are likely to encounter minority group members, human rights issues, and possible hate crimes in their future profession. All the students of the course belong to this group. The main aim of this article is to present this pilot course. To achieve this goal, I describe the pedagogical context first, then the social context and the prejudices present in Hungarian society. The aim of the first section is to place the course described within the context of human rights education using the concept and a typology of affective education. In talking about the latter, the trends of prejudice against the most vulnerable minorities are presented, and hate crimes and incidents committed in Hungary are also described. After introducing the context, the article presents the whole process from planning the curriculum to the realization of the course with all its experiences and challenges. After evaluating the experience some future prospects are presented.

    The paper describes Hungary's energy situation, energy policy and interest in nuclear energy; main targets of the medium-term (by 1990) and long-term (by 2000) nuclear power programme; and preparatory steps for the introduction of nuclear energy. A short technical description is given of the Paks Nuclear Power Station, and of the preparations for construction and erection of Hungary's first nuclear power plant. Fuel supply, basic technical safety aspects and social consequences arising from the plant's erection are discussed. The problems posed by the introduction of nuclear energy which will have to be solved by state administration are summarized. Earlier legislation on projects and works representing radiation danger are described, together with the responsibilities of the various state administrative bodies. Anticipated legal problems are discussed. The participation of Hungarian R and D and design resources in the joint nuclear power development efforts of the CMEA countries is explained and division of design and R and D tasks between various institutes is shown.

    Investigations and discussions were given on a project to implement district heating, greenhouse heating, and binary power generation by utilizing geothermal resources in Hungary. Hungary has deep earth pressure type hot water areas distributed, that flow hot water of about 90 to 180 degrees C by the bed pressure. The areas that can utilize the hot water were extracted and investigated by using literatures and data. The project plans district heating of about 15,000 households using the geothermal water, heating of greenhouses equivalent to 100,000 m{sup 2}, gas engine power generation by using the flowing fluid pressure and combustion of the generated methane gas, and binary power generation by using the geothermal water. As a result of the discussions, it was revealed that the energy saving effect would save 5,008 Ktoe in 20 years as converted to crude oil, and the greenhouse effect gas reducing effect would reduce 14.2 million t-CO2 in 20 years. The total project cost would be about 16.62 billion yen. The internal profit rate of this project is 11.34%, largely exceeding the opportunity cost, and indicating the financial effect possibility.

    Implementation of a new therapy into clinical practice is a complex process. Various countries have different requirements for information but most often focus on economic evaluation, which often plays a stronger role in healthcare decision making than does clinical evidence. To identify all potential challenges in economic evaluation, the case of a new biological drug, rituximab, used to treat rheumatoid arthritis, has been taken as an example. We present methods and results of economic assessment, highlighting the specific issues that should be considered in countries with economic and health care conditions similar to those of Hungary. In principle, economic evaluation requires data on characteristics of target population, disease progression, treatment impact, preferences, resource utilization and unit prices. Treatment effect/relative risk reduction and clinical practice patterns (resource use) may be more generalizable, whereas prices and baseline risk need to be jurisdiction specific. In order to address issues of transferability, investments need to be made in the collection of epidemiological and demographic data, plus data on clinical practice patterns, resource use, costs and health state valuation. In Hungary this problem has been solved through conducting a well designed 255 patient cross-sectional study. The Hungarian example shows that there should be more investment in data collection for those parameters that are thought to differ most from place to place. Owing to the similarities between Central and Eastern Europe countries in health care systems, clinical practice patterns and economic indicators, they may be able to develop partnerships to develop relevant regional databases and registries.

  8. Safer nuclear power. Strengthening training for operational safety at Paks nuclear power plant - Hungary

    International Nuclear Information System (INIS)

    2003-01-01

    For a nuclear power plant, safety must always be paramount. There can be no compromise on safety to meet production targets or to reduce costs. For any reactor, and in particular where older type reactors are in place, their operational safety can be enhanced by upgrading the training of personnel responsible for operating and maintaining the plant. The Department of Technical Co-operation is sponsoring a programme with technical support from the Nuclear Energy and Nuclear Safety Departments to help improve facilities at the PAKS plant in Hungary and establish self sufficiency in training to the highest international standards for all levels of nuclear power plant manpower. The Model Project described will have a direct impact on the improvement of operational safety and performance at PAKS NPP. It will lead to a more efficient use of resources which in turn will result in lower electricity generation costs. The impact of the project is not expected to be limited to Hungary. WWER reactors are common in Eastern Europe and provide one third to one half of the electricity supply to the region. The training programmes and facilities at PAKS offer a possibility in the future to provide training to experts from other countries operating WWER units and serve as a model to be emulated. Slovakia and the Czech Republic have already expressed interest in using the PAKS experience

    Extensive areas in the Brazilian Amazon have been flooded for the construction of hydroelectric dams. However, the water regime of these areas affects the dynamics of igarapés (streams) in adjacent terra firme (upland forests). When the reservoirs are filled, the water levels of streams rise above the normal levels and upland bank forests are flooded. We investigated how this flooding affects the litterfall and nutrient input in the upland forests upstream of a hydroelectric dam reservoir in the Central Amazonia. When the reservoir was filled, the forests were flooded and produced more than twice the litter (8.80Mg·ha -1 yr -1 ), with three times more leaves (6.36Mg·ha -1 yr -1 ) than when they were not flooded (4.20 and 1.92Mg·ha -1 yr -1 , respectively). During flooding, the decomposition rate was four times lower in flooded forests (0.328g·g -1 yr -1 ) than in control forests (1.460g·g -1 yr -1 ). Despite this, the flooding did not favor litter or nutrient accumulation. Therefore, dam construction changes the organic matter and nutrient cycling in upland Amazon rainforests. This may influence the important role that they play in organic matter dynamics and could have consequences for the regional carbon balance and, ultimately, global climate.

    The evaporation (Ep) of a US Class A pan (C) with submerged, freshwater aquatic macrophytes (Potamogeton perfoliatus, Myriophyllum spicatum and Najas marina), hereafter macrophytes (Ps) and a sediment-covered bottom (S) was measured in Hungary during 2014-2015 using reference E of Shuttleworth (Eo) and Penman-Monteith crop reference evapotranspiration (crop ETo). There were two main climatic controls affecting variation in E: direct (air and water temperature) and indirect (wind-mediated change affecting the penetration of sunlight; precipitation inflow, impacting plant emergence). Lower seasonal mean Ep rates of 2.75 ± 0.89, 2.83 ± 0.91 and 3.06 ± 1.14 mm day-1 were observed in C, S and Ps, respectively, during the wet 2014. In the 2015 season, higher overall daily mean Ep rates for C, S and Ps were 3.76 ± 1.3, 4.19 ± 1.34 and 4.65 ± 1.52 mm day-1, respectively. A comparison of US Class A pan Ep containing macrophytes/sediments with that of a standard US Class A pan showed that pan coefficients (Kap and Kas) might allow for more accurate on-site lake E estimates. In 2014, seasonal mean Kas and Kap were 1.04 ± 0.14 and 1.09 ± 0.18, respectively. Slightly higher Ka values were observed during the warm and dry 2015 (Kas: 1.15 ± 0.22; Kap: 1.26 ± 0.23). A Ka value greater than 1 indicates that the Ep of a US Class A pan containing macrophytes and sediment is always higher than that of C. The calculated Eo overestimated measured Ep of Ps during the course of this study. During the warm-dry growing season, crop ETo was closest to Ep of Ps. Empirical coefficients can be useful for estimating E of lakes with submerged macrophytes more precisely. The accuracy of the estimate of Keszthely Bay's E improved by 9.85% when Ka was determined on site.

    This paper introduces the methods and methodological findings of the National Survey on Addiction Problems in Hungary (NSAPH 2015). Use patterns of smoking, alcohol use and other psychoactive substances were measured as well as that of certain behavioural addictions (problematic gambling - PGSI, DSM-V, eating disorders - SCOFF, problematic internet use - PIUQ, problematic on-line gaming - POGO, problematic social media use - FAS, exercise addictions - EAI-HU, work addiction - BWAS, compulsive buying - CBS). The paper describes the applied measurement techniques, sample selection, recruitment of respondents and the data collection strategy as well. Methodological results of the survey including reliability and validity of the measures are reported. The NSAPH 2015 research was carried out on a nationally representative sample of the Hungarian adult population aged 16-64 yrs (gross sample 2477, net sample 2274 persons) with the age group of 18-34 being overrepresented. Statistical analysis of the weight-distribution suggests that weighting did not create any artificial distortion in the database leaving the representativeness of the sample unaffected. The size of the weighted sample of the 18-64 years old adult population is 1490 persons. The extent of the theoretical margin of error in the weighted sample is ±2,5%, at a reliability level of 95% which is in line with the original data collection plans. Based on the analysis of reliability and the extent of errors beyond sampling within the context of the database we conclude that inconsistencies create relatively minor distortions in cumulative prevalence rates; consequently the database makes possible the reliable estimation of risk factors related to different substance use behaviours. The reliability indexes of measurements used for prevalence estimates of behavioural addictions proved to be appropriate, though the psychometric features in some cases suggest the presence of redundant items. The comparison of
