    Attention in this discussion of Romania is directed to the following: people; geography; history; government; political conditions; the economy; foreign relations; defense; and relations between the US and Romania. In 1981 Romania's population was estimated to be 22.4 million. The annual growth rate was 0.9%. The infant mortality rate is 31/1000. In 1974-77 life expectancy was 69.3 years for men and 71.8 years for women. About 88% of the population are ethnically Romanian, a group that is traced to Latin speaking Romans and Thracian, Slavonic, and Celtic ancestors. Most of the minority populations reside in Transylvania or areas to the north and west of Bucharest. The government's policy toward the national minorities is nondiscriminatory and allows them a degree of cultural autonomy. The Jewish community surviving World War 2 has been reduced by more than 90% over the past 3 decades by emigration to Israel. Romania occupies the greater part of the lower basin of the Danube River system and the hilly eastern regions of the middle Danube basin. It lies on either sie of the mountain systems. Romania has had 22 centuries of violent and dramatic history. Romania was an independent kingdom from 1881 until December 30, 1947, when the communist dominated government forced the abdication of King Michael. In March 1945 King Michael was forced to appoint a communist front government. The King abdicated under pressure in December 1947, when the Romanian People's Republic was declared. With their accession to power, the communists effectively subordinated national Romanian interests to those of the USSR. Since the early 1960s, there has been a resurgence of Romanian nationalism and several significant foreign policy differences between Romania and the Soviet Union. The 3 principal branches of government are the unicameral Grand National Assembly, with its Council of State; a centralized executive consisting of a Council of Ministers, operating ministries, and state committees

    One of the most important tributaries of the Danube River in Romania, the Olt River, was characterized in its middle catchment in terms of the isotopic composition using continuous flow-isotope ratio mass spectrometry (CF-IRMS). Throughout a period of 10 months, from November 2010 to August 2011, water samples from the Olt River and its more important tributaries were collected in order to investigate the seasonal and spatial isotope patterns of the basin waters. The results revealed a significant difference between the Olt River and its tributaries, by the fact that the Olt River waters show smaller seasonal variations in the stable isotopic composition and are more depleted in (18)O and (2)H. The waters present an overall enrichment in heavy isotopes during the warm seasons.

    The present study highlights the role of geology (structure and neotectonics) on channel typology in the median and inferior parts of Someş River Drainage Basin (15.470 kmp, 124mc/s), NV Romania, based on channel morphology back in 1860 AD, channel planform dynamics between 1860 and 1977, and geological maps of the area. The geological heterogeneity of the area is responsible for abrupt alternation of different channel types, resulting in a mixture of alluvial and mixed sinuous - meandering - sinuous anabranched - meandering anabranched reaches. Additionally, along some tributaries with reduced flow discharges, lakes are reported behind natural dams imposed by resistant rocks occurred in the river's bed. This behavior is complicated by general slopes of graded profiles, superimposed on local structural and tectonic controls, which enforce the rivers to function on different energy levels. Based on channel typology and planform dynamic prior to large scale hydrotechnical intervention, river position in the floodplain perimeter, the type of rivers (main rivers vs. tributaries with less discharge), a general model of channel adjustment to lithology and neotectonic movements in the NV part of Romania is proposed.

    In this paper we present the dynamics of Somesu Mic River (NW Romania) in relation with the climatic changes over the past 2000 years. The results and discussions are based on 1) documentary evidences of important floods in the area (starting with 1200 AD), 2) the spatial position of old bridges, roads, human settlements related to river position (from the Roman Epoch though the Medieval Period), 3) historical planform river dynamic, based on successive cartographic maps (past 250 years) and 4) OSL and 14C absolute dating of channel fills exposed in the river's bank. The climate in the area was reconstructed using stable isotopes of oxygen and hydrogen in ice cores retrieved from Scarisoara Ice Cave, which display two colder (and possibly more humid) periods between 400 - 900 AD (dark Ages Cold Period - DACP) and 1300-1850 AD (Little Ice Age - LIA), and two warmer (and possibly drier) periods, between 0-400AD (Roman Warm Period - RWP) and 900-1300 AD (Medieval Warm Period - MWP) Our results shows that during periods with high incidence of important floods (LIA), the river readjusts its planform morphology trough meander cut-offs or avulsions on a larger scale, while during periods of reduced incidence of important floods (RWP and MWP), lateral migration became the main river planform process. This behaviour is complicated by geology, reflected in specific local adjustments (e.g. high planform stability, preferential channel migration, avulsion).

    The Aries River basin of western Romania has been subject to mining activities as far back as Roman times. Present mining activities are associated with the extraction and processing of various metals including Au, Cu, Pb, and Zn. To understand the effects of these mining activities on the environment, this study focused on three objectives: (1) establish a baseline set of physical parameters, and water- and sediment-associated concentrations of metals in river-valley floors and floodplains; (2) establish a baseline set of physical and chemical measurements of pore water and sediment in tailings; and (3) provide training in sediment and water sampling to personnel in the National Agency for Mineral Resources and the Rosia Poieni Mine. This report summarizes basin findings of physical parameters and chemistry (sediment and water), and ancillary data collected during the low-flow synoptic sampling of May 2006.

    The morphology of braided rivers was altered by human pressures in the last century in Europe. Rivers from Curvature Subcarpathians have the highest sediment charges in Romania, therefore it seems relevant to evaluate the status of their braided sectors. Therefore, the aim of this work is to carry out an inventory of river morphology alterations suffered by braided rivers in Curvature Subcarpathians and to establish a typology based on indicators for channel adjustments and artificiality. For channel adjustments, we calculated the length of the braided sectors, the width of the active-channels and the length of banks covered by a riparian forest for 1900-2011 interval, in GIS. For artificiality, we counted dams, weirs, bridges, as well as artificial banks length for 2011 time horizon. The results indicate a diminishing braiding activity: all the rivers narrowed their braided active-channel (30-70% of the mean width); the majority suffered fluvial metamorphosis, transforming partially into single channels (0-75% of the braided sector length in 1900); artificial banks vary from 0 to 40% of the initial braided sector. We distinguished three main types of braided rivers based on morphological alterations. Type 1 includes rivers with human interventions and important braiding retraction, both upstream and downstream; a sub-type characterises by riparian forest lining the downstream metamorphosed reach; most rivers are in the south-western part of the studied region; the most demonstrative examples are Prahova and Ialomiţa rivers. Type 2 corresponds to rivers with important retraction upstream, without important values of artificiality; most demonstrative is Râmna River. Type 3 regroups rivers with a low level of channel adjustments and artificiality; actually, they had and still have the highest braiding activity in the studied region; they are located in the north-eastern part; typical examples are Putna and Şuşiţa rivers. As a discussion, the variations of active

    Groundwater, accessed using wells and municipal springs, represents the major source of potable water for the human population outside of major urban areas in northwestern Romania, a region with a long history of metal mining and metallurgy. The magnitude and spatial distribution of metal contamination in private-supply groundwater was investigated in four mining-affected river catchments in Maramureş and Satu Mare Counties through the collection of 144 groundwater samples. Bedrock geology, pH and Eh were found to be important controls on the solubility of metals in groundwater. Peak metal concentrations were found to occur in the Lapuş catchment, where metal levels exceed Dutch target and intervention values in up to 49% and 14% of samples, respectively. A 700 m wide corridor in the Lapuş catchment on either side of the main river channel was identified in which peak Cd (31 μg l(-1)), Cu (50 μg l(-1)), Pb (50 μg l(-1)) and Zn (3,000 μg l(-1)) concentrations were found to occur. Given the generally similar bedrock geologies, lower metal levels in other catchments are believed to reflect differences in the magnitude of metal loading to the local environment from both metal mining and other industrial and municipal sources. Sampling of groundwater in northwestern Romania has indicated areas of potential concern for human health, where heavy metal concentrations exceed accepted environmental quality guidelines. The presence of elevated metal levels in groundwater also has implications for the implementation of the EU Water Framework Directive (WFD) and achieving 'good' status for groundwater in this part of the Danube River Basin District (RBD).

    This paper presents the partial results obtained into the project CLIMHYDEX ("Changes in Climate Extremes and associated impact on hydrological events in Romania") project that, among others, have as objectives the development of hydrological models at different spatial and temporal scales and the impact of climate change on extreme runoff in Bârlad catchment. To estimate the impact of climate change and variability on the flow regime in Bârlad catchment CONSUL hydrological model, with lumped parameters, was used. This rainfall-runoff deterministic model simulates the most significant hydrological processes within a hydrographic basin: snow-melting, interception, retention in the depressions, evapotranspiration, infiltration, surface runoff, hypodermic runoff, percolation, base runoff. According to the schematic representation (physiographic modelling) of how water flows and collects in a river basin the model computes the discharge hydrographs on selected simulation points on the river network and then performs their routing and composition on the main river and tributaries. After physiographic modelling resulted for Bârlad river basin: 56 sub-basins and 30 river reaches. CONSUL model was calibrated using historical data in Bârlad river basin by simulating the flow during 1975-2010. Calculation of average precipitation and air temperature (hydrological model input data) for each sub-basin was performed using a pre-processing program of meteorological data from original rectangular grid nodes corresponding to Bârlad river basin, averaging being achieved as weighted values based on the representativeness of these nodes for each analyzed sub-basin. In order to estimate the initial values of CONSUL model parameters the generalization relationships of these parameters based on morphometric characteristics of the river basin or river reach were used. Calibration of model parameters was performed in two stages: (i) individual and (ii) globally. (i) Individual

    Danube delta, one of the largest European wetlands left, lies predominantly in Romania, being considered a Biosphere Reservation. Environmental impact assessment and detection of spatio-temporal changes is needed for protection, conservation and restoration of the biological diversity specific to this area. Danube Delta wetlands and aquatic ecosystem are increasingly endangered by global or regional environmental changes due to the discharges or deposition of excess nutrients and/or harmful substances, to the reclamation of lands for agriculture, forestry, and engineering of water flows. A multitemporal data set consisting of LANDSAT MSS, TM and SAR-ERS1 images for Romanian Danube River Delta was used for comparing and mapping landcover change via change detection. The main aim of this paper is to conduct a comprehensive analysis based on existing historical and more recent data to establish the link between phytoplankton bloom development and related harmful phenomena in the North-Western part of Black Sea and changes in the Danube watershed (landuse, fertilizer utilization, waste water treatments). Based on satellite data were analyzed some test areas in the vicinity of the Danube mouths where the nutrient concentration were highest, being assimilated with an expected oxygen depletion, sulfate reduction and methanogenesis in the bottom waters and the superficial sediments.

    The river basin management and flood depends on the politico-historical, economic and environmental context in which it is thought. There is a similar evolution in Romania, where political developments have had as much impact on flood management than hydro-climatic events. The aim of this work is to understand of management systems in a diachronic logic in Romania from the beginning of the 20th century to the Communist period and to accession to the European Union. This work focuses on the lower Siret River. The Siret catchment is one of the last major tributaries of the Danube River east of the Carpathians and the most important of Romania in terms of flow and drainage area. To study the assessment of river basin management, a GIS was constructed using a series of Romanian and Russian topographic maps extending over the period 1916-1990 and Google earth images from 2009 and 2010. The study of the current period was enhanced by field observations (records of existing dykes, testimonials ...) from 2010-2011. Finally, this study is based on the technical literature for the regularization of rivers and the various reports made over this period. Three periods were identified: the major floods of 1970 and 2005 marked a turning point in the logical management of river basin and especially in the fight against flood. From the beginning of the period to 1970, dyke protection was sporadic: they are intended primarily to protect the villages directly threatened by recurrent flood. In 1970 a major flood (3500 m3/s) occurred on the lower Siret and other minor floods in succession from 1970 to 1975. By 1976 a national plan was drawn up to fight against the harmful effects of water. The entire sector of the lower Siret River and its major tributaries is arranged, a network of levees protects not only the villages but also all economic assets in this sector, namely the agricultural land, the main wealth of the region. In 2005 an exceptionally large flood (4650 m3/s) affected the

    The present study focuses on flash flood modeling on several mountaneous catchments situated in Western Romania by the use of two methodologies, when rainfall and catchment characteristics are known. Hence, the Soil Conservation Service (SCS) Method and the Rational Method will be employed for the generation of the 1%, 2% and 10% historical flash flood hydrographs on the basis of data spanning from 1989-2009. The SCS Method has been applied on the three gauged catchments in the study area: Petris, Troas and Monorostia making use of the existing interconnection between GIS and the rainfall-runoff models. The DEM, soil data and land use preprocessing in GIS allowed a determination of the hydrologic parameters needed for the rainfall-runoff model, with special emphasis on determining the time of concentration, Lag time and the weighted Curve Number according to Antecedent Moisture Conditions II, adapted for the Romanian territory. HEC-HMS rainfall-runoff model (Hydrologic Engineering Center- Hydrologic Modeling System) facilitates the historical 1%, 2% and 10% flash flood hydrograph generation for the three afore mentioned watersheds. The model is calibrated against measured streamflow data from the three existing gauging stations. The results show a good match between the resulted hydrographs and the observed hydrographs under the form of the Peak Weighted Error RMS values. The hydrographs generated by surface runoff on the ungauged catchments in the area is based on an automation of a workflow in GIS, built with ArcGIS Model Builder graphical interface, as a large part of the functions needed were available as ArcGIS tools. The several components of this model calculate: the runoff depth in mm, the runoff coefficient, the travel time and finally the discharge module which is an application of the rational method, allowing the discharge computation for every cell within the catchment. The result consists of discharges for each isochrones that will be subsequently

    Over the last decades, the Holocene evolution of the rivers became an important topic for the scientific community. Whereas most of these studies emphasized the role of climate in the rivers' evolution, little attention has been paid to tectonics, especially at small scale. Here we present a model of Holocene river evolution from the Transylvanian Basin (Romania), where salt tectonics plays an important role. Someşul Mic River (105 km long, 20 mc/s) is located in the NW part of the Transylvanian Basin, Romania. It has a dranage basin of 3773 km2 and the catchment's area is located in the Apuseni Mountains. The river has a well-developed floodplain, with a length of 75 km (calculated along its axis) and an average width of 2 km. In the upper sector, the river flows on red clays, sandstones and limestone of Eocene and Oligocene age (disposed in monoclinal strata), while in the lower sector, the bedrock consists of marls and volcanic tuffs of Miocene age, affected by diapiric alignments. The sedimentary structure of the floodplain is simple, with coarse Lateglacial gravels at the bottom and more fine Holocene sediments (pebble, sand, clay and silt) in its upper part; but some deviations from this general model, attributed to active tectonics, are observed along the river (e.g., absence of the coarser complex, variable proportion of the two complexes, etc). The main characteristic of the river is the high degree of alternation of channel types, from sinuous, meandering and even braided, to anabranched reaches. In order to decipher which mechanism is responsible for the development of the floodplain, we have analyzed in detail a section of the river, using a combination of high-resolution topographic surveys, electrical imaging, core drilling and granulometric analyses. In the investigated area, the river flows on Miocene marls partly covered by sediments, having a sinuous reach, with 2-3 m high banks. To the east, a diapiric syncline stretches parallel to the valley

    The Romanian government is interested in understanding the effects of existing and future mining activities on long-term dispersal, storage, and remobilization of sediment-associated metals. An initial Soil and Water Assessment Tool (SWAT) model was prepared using available data to evaluate hypothetical failure of the Valea Sesei tailings dam at the Rosia Poieni mine in the Aries River basin. Using the available data, the initial Aries River Basin SWAT model could not be manually calibrated to accurately reproduce monthly streamflow values observed at the Turda gage station. The poor simulation of the monthly streamflow is attributed to spatially limited soil and precipitation data, limited constraint information due to spatially and temporally limited streamflow measurements, and in ability to obtain optimal parameter values when using a manual calibration process. Suggestions to improve the Aries River basin sediment transport model include accounting for heterogeneity in model input, a two-tier nonlinear calibration strategy, and analysis of uncertainty in predictions.

    Moldova River is a 205 km long river, right tributary of the Siret River, with the confluence close to Roman city. The most important tributaries are Moldoviţa, Suha Mică, Suha Mare, Râsca, Ozana and Topolita Rivers. The drainage basin area is 4316 km2, a discharge of about 32.8 m3/s and is superimposed on four lithostratigraphic units: the crystalline Mesozoic unit, the flysch unit, the molasse unit and the platform unit. The study reach is 110 km long and is located on the external part of the Eastern-Carpathians at the contact with the Moldavian Plateau. This contact is characterised by a piedmont zone. The high rate of alluviation in this piedmont plain had a decisive role on the spatial and temporal evolution of fluvial forms and processes, expressed in the morphology of alluvial terraces in the valley bottom, the morphology of the active channel, the spatial distribution of bars and secondary channels and lateral migration rates. The morphology of the river in the study reach is dominated by braided and wandering channel patterns. The present (2005) active channel width ranges between 700 and 1000 m. Planform changes of river features over the last 100 years were analyzed on three historical maps (1910, 1960, and 1980) and one orthophoto (2005). Channel width average has significantly decreased in the last century. The Moldova river channel width suffered a strong narrowing, approximately 76% (from 1910 to 2005). So, from a channel width about more than 1200 m, it decreased at about 300 m. We can note two phase of narrowing: a first one - stronger, of 56%, untill 1960 (a reduction of active channel width for about 10.5 m/year) and a second phase, of 35%, after 1960, with a narrowing rate for about 8.8 m/an. The historical trend of braiding index shows a remarkable decrease in the last 50 - 60 years, from 3.2 in 1960, at 2.6 in 1980 and 2.0, in 2005, for all the extra-Carpathian study reach (110 km). There are different situations at local scale, shown

    Upstream migrant adults of stellate sturgeon, Acipenser stellatus (10 in 1998, 43 in 1999) and Russian sturgeon, A. gueldenstaedtii (three in 1999) were captured at river km (rkm) 58-137, mostly in the spring, and tagged with acoustic tags offering a reward for return. The overharvest was revealed by tag returns (38% in 1998, 28% in 1999) and by harvest within 26 days (and before reaching spawning grounds) of the six stellate sturgeon tracked upstream. A drop-back of > 50% of the tagged sturgeon, some to the Black Sea, shows a high sensitivity to interruption of migration and capture/handling/holding. Harvesting and dropback prevented tracking of sturgeon to spawning sites. Gillnetting and tracking of stellate sturgeon showed that the autumn migration ended in early October (river temperature 16??C) and identified a likely wintering area at river km (rkm) 75-76 (St George Branch). Thus, fishery harvesting after early October captures wintering fish, not migrants. Rare shoreline cliffs in the lower river likely create the only rocky habitat for sturgeon spawning. A survey for potential spawning habitats found five sites with rocky substrate and moderate water velocity, all ???rkm 258. Drift netting caught early life-stages of 17 fish species and one sturgeon, a beluga, Huso huso, larva likely spawned at ???rkm 258. All diadromous Danube sturgeons likely spawn at ???rkm 258.

    Sediment budgets are a useful tool for geomorphologic analysis, catchment management and environmental assessment, despite the uncertainties related to their assessment. We present the sediment budget construction and validation for a small catchment of 9.5319 kmp (953.19 ha) situated in the North-Eastern part of Romania. The Rediu reservoir was built between 1986 and 1988, on Rediu valley, a left tributary of Bahlui river, north-west from Iasi city. The catchment of the reservoir has 6.5 km in length and 2.5 km in maximum width, the altitudes decreasing from 170 m in the northern part, to 52 m in the southern part. The valley is symmetric, the altitude of the hillslopes going between 200 m to 75 m in one km length, in the transversal section with the maximum width. The floodplain is narrow having between 20 m to 210 m (in the area of confluence with Breazu tributary). The mean slope of the catchment is 6.4 degree, the maximum slope being 24.6 degrees. The length of channels which show banks of up to 2 m is 19.98 km. The land is used predominantly as crops (58.1 %), 16.7 % being covered by pastures (from which over half are eroded), 11.5 % percent of the catchment being covered by planted forests, 9.2 % by rural constructions and roads, 2.9 % by hayfields, 1.5 % by lakes and 0.1 % by orchards. Beside the Rediu reservoir, there are three ponds (15 771, 1761 and 751 sqm) in the catchment. We considered the trap efficiency for the reservoir and the ponds to be 95%. Aerial images from 1963, 1978 , 1984, 2005, 2008, 2010, 2012 and 2014 were used to assess the state of geomorphological processes before and after the reservoir construction. After 1970 a gully system situated in Breazu tributary sub-catchment and several active landslides along the main valley left side were forested. Beside these processes, soil erosion and human impact by constructions are the main processes generating sediment in the study area. The sediment yields were quantified by estimating the

    The paper presents the partial results, obtained within the CLIMHYDEX project (www.climhydex.meteoromania.ro), regarding the assessment of the climate change impact on flow regime from Bârlad River Basin by long term hydrological simulation. To estimate the impact of variability and climate change on monthly mean, seasonal and annual flow regime, in the Bârlad River Basin, the long-term simulations were performed, by means of CONSUL hydrological model, using as input data series of precipitation and temperature resulted from the data processing obtained from simulations of climate evolution by means of regional climate model REMO having spatial resolution of 10 km. The CONSUL model is a deterministic hydrological mathematical model which allows the simulation of flow in small as well as in large and complex basins, divided into homogeneous units (sub-basins). The model enables the computing of discharge hydrographs on sub-basins, their routing and composition on the main river and tributaries. Using of CONSUL model assumed the calibration of model parameters, an operation that was performed by the simulation of flow from the period 1975 - 2010 in the analysed river basin. Calibration of model parameters was performed in two stages: based on events and global. Calibration based on events was made considering 25 rainfall-runoff events, chosen to cover a wide range of possible situations in the case of floods formation. Global calibration of rainfall-runoff model parameters was done by simulating the flow on considered calibration period. Flow simulations using the CONSUL model, having optimal parameters derived from the calibration process, were conducted for two periods: the reference period 1971 - 2000 and the future period 2021 - 2050 respectively, at 9 hydrometric stations from the river basin analysed. For the input data in the CONSUL model, i.e. precipitation and temperature series, averaged on the sub-basins corresponding to the gauge stations, a comparative

    Mining activities have a long history in the Aries catchment. The extraction of precious metals containing ores culminated in the mid 20th century and then decreased continuously. The mining industry created a beneficial economic development of the region but the negative environmental impact due to acid mine drainage combined with heavy metal pollution of surface waters still remains, after most of the mining operations were closed. This study presents the results of a monitoring surveillance of heavy metal concentrations in surface waters from 12 monitoring stations along the Aries River, during March-October 2008. The results showed that downstream of mining activities an increase of all metal concentrations in surface waters was observed, but the water quality improved with the distance from contaminant sources due to the dilution effect of less polluted tributaries.

    The purpose of this study was to monitor and record the specific characteristics and properties of the Arges River water in the Budeasa Reservoir (the principal water resources of municipal tap water of the big Romanian city Pitesti and surrounding area) for a period of 5 years (2005-2009). The monitored physical and chemical parameters were turbidity, pH, electrical conductivity, chemical oxygen demand, 5 days biochemical oxygen demand, free dissolved oxygen, nitrite, nitrate, ammonia nitrogen, chloride, total dissolved iron ions, sulfate, manganese, phosphate, total alkalinity, and total hardness. The results were discussed in correlation with the precipitation values during the study. Monthly and annual values of each parameter determined in the period January 2005-December 2009 were used as a basis for the classification of Budeasa Reservoir water, according to the European legislation, as well as for assessing its quality as a drinking water supply. Principal component analysis and Pearson correlation coefficients were used as statistical procedures in order to evaluate the data obtained during this study.

    The purpose of this study was to monitor and record the specific characteristics and properties of the Arges River water in the Budeasa Reservoir (the principal water resources of municipal tap water of the big Romanian city Pitesti and surrounding area) for a period of 5 years (2005-2009). The monitored physical and chemical parameters were turbidity, pH, electrical conductivity, chemical oxygen demand, 5 days biochemical oxygen demand, free dissolved oxygen, nitrite, nitrate, ammonia nitrogen, chloride, total dissolved iron ions, sulfate, manganese, phosphate, total alkalinity, and total hardness. The results were discussed in correlation with the precipitation values during the study. Monthly and annual values of each parameter determined in the period January 2005-December 2009 were used as a basis for the classification of Budeasa Reservoir water, according to the European legislation, as well as for assessing its quality as a drinking water supply. Principal component analysis and Pearson correlation coefficients were used as statistical procedures in order to evaluate the data obtained during this study. PMID:27566323

    Tracing pollution sources and transformation of nitrogen compounds in surface- and groundwater is an issue of great significance worldwide due to the increased human activity, translated in high demand of water resources and pollution. In this work, the hydrological basin of an important chemical industrial platform in Romania (Ramnicu Valcea industrial area) was characterized in terms of the physico-chemical and isotope composition of δ(18)O and δ(2)H in water samples and δ(15)N of the inorganic nitrogen species. Throughout a period of one year, water samples from the Olt River and its more important tributaries were collected monthly in the industrial area, when the seasonal and spatial isotope patterns of the surface waters and the main sources of pollution were determined. Higher inorganic nitrogen concentrations (up to 10.2 mg N L(-1)) were measured between November 2012 and April 2013, which were designated as anthropogenic additions using the mixing calculations. The main sources of pollution with inorganic nitrogen were agriculture and residential release. The inorganic nitrogen from the industrial waste water duct had a distinct δ(15)N fingerprint (mean of -8.6‰). Also, one industrial release into the environment was identified for Olt River, at Ionesti site, in November 2012. The mean precipitation samples had the lowest inorganic nitrogen concentrations (less than 5.5 mg N L(-1)) with a distinct δ(15)N fingerprint compared to the surface and industrial waters.

    Keywords: diatom communities, indicator species, mine waters, water quality, Romania. Diatoms are a very distinct group of algae, identifiable under the light microscope by their yellow - brown coloration and by the presence of a thick silica cell wall. The potential for freshwater organisms to reflect changes in environmental conditions was first noted by Kolenati (1848) and Cohn (1853), who observed that biota in polluted waters were different from those in non-polluted situations. Diatoms are widely used to monitor river pollution because they are sensitive to water chemistry, especially to ionic content, pH, dissolved organic matter and nutrients. Wide geographic distribution and well-studied ecology of most diatom species are mentioned as major advantages of using diatoms as indicator organisms. At the same time water quality has begun to deteriorate increasingly, mainly as a result of the physical, chemical and bacteriological alterations, and the aquatic ecosystems are evermore affected by various types of pollution, the anthropic one being almost always included. A good example is Abrud River and its main tributaries (Roșia Montană and surrounding areas, Romania), which has suffered along the years because of the mining waters discharge. In this context, this study presents data on benthic diatom communities from the Abrud River catchment area. Sixteen sites have been sampled seasonal and the best represented diatom genera were Navicula, Nitzschia, Cymbella, Gomphonema, Achnantes, Surirella and Fragilaria. Qualitatively, the number of diatom species exhibited significant variation among sampling sites, also suggesting seasonal dynamics. For instance, in some sampling sites, algal assemblages were absent, as diatom communities were strongly affected by acid mine waters, released from old mining works and waste rocks depots. Some dominant taxa have been observed as well, suggesting critical saprobic levels of the Abrud River and some of its tributaries. The

    Pollution of the aquatic environment by heavy metals is a great concern worldwide. Freshwater fish ingests various metals through gills, skin or diet. Our aim was to investigate the oxidative stress and histopathological injuries induced by Fe, Cu, Zn, Pb, Cd in the liver and kidney of Leuciscus cephalus. Fish samples were collected from two sites in the Tur River, NW Romania, in upstream and downstream of a pollution source. Metals were differently distributed in the liver and kidney of fish. The highest concentrations of Fe, Cu and Pb were found in liver, whereas Zn and Cd concentrations were the highest in kidney in specimens collected from the downstream site. The histopathological changes were associated with metal bioaccumulation, being more severe in kidney than liver. Malondialdehyde (MDA) and advanced oxidation protein products (AOPP) increased significantly in the liver and kidney of fish from downstream site compared to upstream one, whereas reduced glutathione (GSH) decreased. The activities of superoxide dismutase (SOD), catalase (CAT) and glutathione-S-transferase (GST) increased significantly in livers, whereas SOD increased in kidney. Our study revealed that liver has a higher capacity and adaptability to counteract ROS compared to kidney. The more pronounced increase of hepatic SOD, CAT and GST activities is related milder structural changes observed in liver compared to kidney, where lesions were not reduced by antioxidant defense system.

    Chlor-alkali plants using mercury (Hg) cell technology are acute point sources of Hg pollution in the aquatic environment. While there have been recent efforts to reduce the use of Hg cells, some of the emitted Hg can be transformed to neurotoxic methylmercury (MeHg). Here, we aimed (i) to study the dispersion of Hg in four reservoirs located downstream of a chlor-alkali plant along the Olt River (Romania) and (ii) to track the activity of bacterial functional genes involved in Hg methylation. Total Hg (THg) concentrations in water and sediments decreased successively from the initial reservoir to downstream reservoirs. Suspended fine size particles and seston appeared to be responsible for the transport of THg into downstream reservoirs, while macrophytes reflected the local bioavailability of Hg. The concentration and proportion of MeHg were correlated with THg, but were not correlated with bacterial activity in sediments, while the abundance of hgcA transcript correlated with organic matter and Cl(-) concentration, indicating the importance of Hg bioavailability in sediments for Hg methylation. Our data clearly highlights the importance of considering Hg contamination as a legacy pollutant since there is a high risk of continued Hg accumulation in food webs long after Hg-cell phase out.

    The present work focuses on the analyses of a selection of heavy mineral assemblages sampled from the Neagra Şarului River's alluvia, in order to determine their provenance and distribution, using their geochemical and physical characteristics. The study focused on a mountain river of about 30 km long, located in the north-western part of the Eastern Carpathians, an important tributary of the Bistria River. The bedrocks in the river drainage basin are constituted mainly by igneous rocks from Călimani Volcanic Complex in the west, and secondarily by a small area of low to medium grade metamorphic rocks, part of Crystalline-Mesozoic Zone, in the east. In order to trace the source of each individual mineral species, we prepared our samples via field separation and subsequent laboratory sieving using 8 different size fractions. An electromagnetic separator (Frantz Isodynamic) was used to separate and classify each heavy minerals species, depending on their magnetic susceptibility. Thus prepared, more than 500 grains per samples (from the 0.5-1 mm size fraction) were mounted on thin sections and analyzed using a Cambridge Microscan M9 with EDS system. These analyses served for mineral identification and relative abundance determination. The classification of the minerals and the nature of their inclusions are derived from the major element compositions computed from SEM-EDX analysis. We also used a stereo microscope in order to determine complementary properties of the grains, such as: color, degree of roundness and degree of alteration. In order of abundance, the main heavy minerals are magnetite, hematite, pyroxene, pyrite, manganese oxides, garnet, apatite, titanium oxides (ilmenite, titanite and rutile/anatase), chlorite, olivine, epidote, biotite and rhodochrosite. A particularity of the studied area is the presence of an altered magnetite caused first by the hydrothermal alteration and strong weathering of the source rocks and second by the river's acid water

    The inventory of long-term braiding activity is a useful tool for detecting alterations in a rivers' hydromorphological state and for a river's management in the context of the Water Framework Directive on integrated river basin management for Europe. Our study focuses on braided sectors of rivers in South-Eastern Subcarpathians (Romania). The inventory evaluates types of alterations based on the spatial analysis of fluvial morphology indicators (i.e., length of the river sector forming a braided pattern; width of the braided active channel), and vegetation cover (i.e., length of banks covered by forest and shrubs; area of in-stream patches of shrubs) accumulated over the last century. Furthermore, we performed a regional scale hierarchical cluster analysis to estimate the degree of alteration when compared to an historical baseline. In South-Eastern Subcarpathians, the studied rivers experienced a decrease of braiding activity revealed by the shortening and narrowing of their braided sectors, expansion of riparian forests, and the diminishment of vegetated islands' areas. We separated three types of river clusters, corresponding to low (cluster 1), moderate (cluster 2), and high (cluster 3) degree of alteration. Moreover, the clusters demonstrate the evolutionary path of the braided pattern alterations until the functioning of another channel pattern. The inventory is relevant for differing types and levels of alterations. Additionally, this tool may serve as a first step toward the restoration of altered sectors by identifying rivers in cluster 1 as potential candidates of present-day reference sites for altered rivers with similar natural conditions as in cluster 3.

    The River Basin Management Plan is the main instrument for the implementation of the Water Framework Directive (2000/60/CE), one of its main requirements being the evaluation and quantification of human impacts on aquatic environments including the groundwater or groundwater dependent ecosystems. The Someş-Tisa basin is the largest hydrographical basin in NW Romania (22,380 km2), containing 15 Quaternary detrital groundwater bodies prone to intensive agricultural and urban industrial use. So far, no studies have addressed the groundwater fauna assemblages and their ecological response to human disturbances and aquifer contamination. Here we investigate a Quaternary shallow detrital aquifer (< 30 m depth) associated with the Someşul Mic River affected by both urban-industrial and agricultural contaminants, aiming to evaluate the sensitivity and structural patterns of groundwater crustaceans communities to aquifer contamination with trace metals (Cr, Mn, Co, Ni, Cu, Zn, Cd, Mo, Pb), As, Se and nitrates. We conducted a survey in seven monitoring boreholes (1-8 m beneath the surface) through the Quaternary porrous aquifer of the Somesul Mic River on a 10 km long longitudinal transect. Hydrologic and geologic variables (rainfall amount, drainage network density, aquifer and drainage elevation, transmisivity and aquifer porosity) were extracted from previous works and Pearson correlations were calculated for paired variables. Water and faunal sampling was performed on a seasonal basis at one pristine and six impacted sites during 2013. Invertebrates were sampled with a submersible pump by extracting a volume of 50-100 l of water and filtering through a 63 microns planktonic net. Subsequently, 2 l of water was extracted after pumping for compositional analyses of major constituents, trace elements (by ICP-MS) and nutrients. The results of water geochemical analyses indicate a significant pollutant charge of groundwater with Mn (max. 29.26 μg/l), Ni (16.55 μg/l), Fe

  10. Synergies between geomorphic hazard and risk and sediment cascade research fields: exploiting geomorphic processes' susceptibility analyses to derive potential sediment sources in the Oltet, river catchment, southern Romania

    Identifying sediment sources and sediment availability represents a major problem and one of the first concerns in the field of sediment cascade. This paper addresses the on-site effects associated with sediment transfer, investigating the degree to which studies pertaining to the field of geomorphic hazard and risk research could be exploited in sediment budget estimations. More precisely, the paper investigates whether results obtained in assessing susceptibility to various geomorphic processes (landslides, soil erosion, gully erosion) could be transferred to the study of sediment sources within a basin. The study area is a medium-sized catchment (> 2400 km2) in southern Romania encompassing four different geomorphic units (mountains, hills, piedmont and plain). The region is highly affected by a wide range of geomorphic processes which supply sediments to the drainage network. The presence of a reservoir at the river outlet emphasizes the importance of estimating sediment budgets. The susceptibility analyses are conducted separately for each type of the considered processes in a top-down framework, i.e. at two different scales, using scale-adapted methods and validation techniques in each case, as widely-recognized in the hazard and risk research literature. The analyses start at a regional scale, which has in view the entire catchment, using readily available data on conditioning factors. In a second step, the suceptibility analyses are carried out at a medium scale for selected hotspot-compartments of the catchment. In order to appraise the extent to which susceptibility results are relevant in interpreting sediment sources at catchment scale, scale-induced differences are analysed in the case of each process. Based on the amount of uncertainty revealed by each regional-scale analysis in comparison to the medium-scale ones, decisions are made on whether the first are acceptable to the aim of identifying potential sediment source areas or if they should be

    According to the International Decade for Natural Disaster Reduction (IDNDR 1990-1999), the risk indicates potential losses due to particular natural phenomenon, and these could be reduced by improving of prevention and education. People perceive these losses differently depending on phenomenon occurrence, severity, and impact in time. Starting from this idea, this research presents public perception on land degradation through erosion in a small area from the central part of Romania (south-west of Transylvanian Depression). The research was based on a questionnaire consisting of 16 questions. The items were structured by issues: awareness assessment regarding hazard and risk phenomena, assessment of type of property and land use, assessment of knowledge and information on the possible production of negative effects by natural phenomena, and evaluation of land owners' attitudes towards the occurrence of erosion on their land. Results reveal that the public perception on erosion is weak. This process is perceived as insignificant due to lack of phenomenon knowledge and especially because of scarcity preoccupation in land's quality monitoring. Even though the owned lands are affected by erosion forms, the owners are not aware of the phenomenon that generates them. Material damages caused by erosion, loss of soil quality, and land fertility decrease are less perceived because the economic losses fill only at long term. This perception leads to underestimating erosion risk compared to other natural phenomena and to a passive attitude towards this particular phenomenon.

    Romania has a high potential of mineral waters resources, featuring one of the largest mineral resources at European and global level. In the last decade, due to increased in consumption of bottled water, numerous brands have appeared on the market, with equally numerous and variable sources of provenance. In this study we have analyzed the isotopic composition of bottled mineral waters from Romania in order to determine their source and authenticity. We have analysed 32 carbonated and 24 non-carbonated mineral waters from Romania. and the results were analysed in comparison with stable isotope data from precipitation and river waters. Generally, the isotopic values of the mineral waters follow those in precipitation; however, differences occur in former volcanic regions (due to deep circulation of meteoric waters and increased exchange with host rock and volcanic CO2), as well as in mountainous regions, where high-altitude recharge occurs.

    This analysis of the Romanian health system reviews recent developments in organization and governance, health financing, health care provision, health reforms and health system performance. The Romanian health care system is a social health insurance system that has remained highly centralized despite recent efforts to decentralize some regulatory functions. It provides a comprehensive benefits package to the 85% of the population that is covered, with the remaining population having access to a minimum package of benefits. While every insured person has access to the same health care benefits regardless of their socioeconomic situation, there are inequities in access to health care across many dimensions, such as rural versus urban, and health outcomes also differ across these dimensions. The Romanian population has seen increasing life expectancy and declining mortality rates but both remain among the worst in the European Union. Some unfavourable trends have been observed, including increasing numbers of new HIV/AIDS diagnoses and falling immunization rates. Public sources account for over 80% of total health financing. However, that leaves considerable out-of-pocket payments covering almost a fifth of total expenditure. The share of informal payments also seems to be substantial, but precise figures are unknown. In 2014, Romania had the lowest health expenditure as a share of gross domestic product (GDP) among the EU Member States. In line with the government's objective of strengthening the role of primary care, the total number of hospital beds has been decreasing. However, health care provision remains characterized by underprovision of primary and community care and inappropriate use of inpatient and specialized outpatient care, including care in hospital emergency departments. The numbers of physicians and nurses are relatively low in Romania compared to EU averages. This has mainly been attributed to the high rates of workers emigrating abroad over the

    The HEU spent nuclear fuel transport from Romania was a pilot project in the framework of the Russian Research Reactor Fuel Return Program (RRRFR), being the first fully certified spent nuclear fuel shipment by air. The successful implementation of the Romanian shipment also brought various new technology in the program, further used by other participating countries. Until 2009, the RRRFR program repatriated to the Russian Federation HEU spent nuclear fuel of Russian origin from many countries, like Uzbekistan, Czech Republic, Latvia, Hungary, Kazakhstan and Bulgaria. The means of transport used were various; from specialized TK-5 train for the carriage of Russian TUK-19 transport casks, to platform trains for 20 ft freight ISO containers carrying Czech Skoda VPVR/M casks; from river barge on the Danube, to vessel on the Mediterranean Sea and Atlantic Ocean. Initially, in 2005, the transport plan of the HEU spent nuclear fuel from the National Institute for R&D in Nuclear Physics and Nuclear Engineering 'Horia Hulubei' in Magurele, Romania considered a similar scheme, using the specialized TK-5 train transiting Ukraine to the destination point in the Russian Federation, or, as an alternative, using the means and route of the spent nuclear fuel periodically shipped from the Bulgarian nuclear power plant Kosloduy (by barge on the Danube, and by train through Ukraine to the Russian Federation). Due to impossibility to reach an agreement in due time with the transit country, in February 2007 the US, Russian and Romanian project partners decided to adopt the air shipment of the spent nuclear fuel as prime option, eliminating the need for agreements with any transit countries. By this time the spent nuclear fuel inspections were completed, proving the compliance of the burn-up parameters with the international requirements for air shipments of radioactive materials.

    In Romania, nine onshore petroleum systems and one offshore petroleum system have recently been identified. Of the onshore systems, three are related to the compressional folded basins: Teleajen-Sita (early Middle Cretaceous marine source rocks), and Puciossa-Fusaru and Alunis-Kliwa (Oligocene-early Miocene marine source rocks). In the same category, we have included the recently discovered Deleni petroleum system with source rocks of not yet identified origin but whose reservoirs certainly belong to a folded basin. In the foreland platform basins, two systems can be distinguished: Rimesti-Fauresti (Middle Jurassic marine source rocks) and Infra-Anhydrite (with presumed Middle Jurassic or middle Miocene marine source rocks). The areas corresponding to the posttectonic basins include three onshore petroleum systems and one offshore system: the Pannonian (Badenian marine and Sarmatian brackish water source rocks), the Valea Caselor-Borsa (oligocene marine source rocks) and the Transylvanian (Badenian marine shales source and Sarmatian brackish water source rocks). Offshore, there is only one petroleum system consisting of Oligocene-Miocene marine source rock and Cretaceous or Eocene reservoirs. The majority of the mentioned petroleum systems reservoirs are Paleozoic to Pliocene clastics, but in the platform areas, carbonate reservoirs are found in the Paleozoic and Mesozoic. In all the petroleum systems, despite the different ages of the source rocks, most of the hydrocarbons have been expelled relatively recently during the Late Sarmatian-Pliocene interval. This face is substantiated by examples from two petroleum systems: the Rimesti-Fauresti (duration time 173 m.y., preservation 2 m.y.) and the Alunis-Kliwa (duration time 29-30 m.y., preservation 4 m.y.). The hydrocarbons were first expelled and migrated into described systems reservoirs after Late Styrian and Moldavian overthrusting, i.e. not earlier than 12-14 m.y.

    The concept of open data access is a very important topic nowadays. The concept assumes that all data collected or generated by public sector bodies (excepting personal data and data protected under existing privacy protection or accessibility rules) is made publicly accessible in commonly-used, machine-readable formats and can be re-used for any purpose, commercial or non-commercial. Governmental agencies are considered to be the most significant data owners and providers in modern societies. The sheer volume and wealth of this data makes apparent the potential benefits of reusing, combining, and processing governmental data. Even though metadata (information about the data) is sometimes published, administrations typically express reluctance to making their data available, for various reasons, cultural, political, legal, institutional and technical. The governmental spatial information (also called geospatial data, georeferenced data or geodata) producers in Romania are no exception -with the additional situation that even metadata is not usually available. Starting from 2013 a joint program between a Swiss partner (The Swiss Federal Institute of Technology ETH- Zurich - Institute of Cartography and Geoinformation) and a Romanian partner (Technical University of Civil Engineering - UTCB) is developed in order to establish a new approach on the open geodata topic. The main objective of the project GEOIDEA.RO (GEodata Openness Initiative for Development and Economic Advancement in ROmania) is to improve the scientific basis for open geodata model adoption in Romania. Is our believe that publishing government geodata in Romania over the Internet,under an open license and in a reusable format can strengthen citizen engagement and yield new innovative businesses, bringing substantial social and economic gains.

    Oradea is located on the Crisul Repede River, in the northwestern corner of Romania almost due west of Budapest, Hungary. The city has a population around half a million people and can trace its origins back to the Neolithic Age. It was an urban settlement beginning in the 13th century and has been an economic and cultural center for the region. It is a geothermal city with 12 wells drilled within the city limits, six in the nearby Felix Spa and five in the Bors geothermal area to the west, with one doublet set at Nufarul. Currently, there are a variety of geothermal uses in the area, including space and greenhouse heating, domestic hot water supply, process heat, balneology and swimming pools. Wellhead temperatures range from 70 to 105{degrees}C with artesian flows of from 5 to 25 L/s. The present installed capacity is 25 MWt and the heat supply is estimated at 60,000 MWh per year (216,000 GJ/yr). With pumping, the production would double and adding four more doublets, the installed capacity be increased to 65 MWt.

    As viewed on a map, the borders of Alba County, which lies in the centre of Transylvania, resembles the shape of a heart. The landscape is of great diversity: the plain of the river Mureş and the Apuseni Mountains. These surroundings are bestowed with three types of gold: yellow gold-Au, green gold - the forests and blue gold - water, joined with the red and brown nuances of specific flora and fauna. Every spring the Forestry Service of Alba Iulia and the association "Silvic Progress" initiate and promote events designed to raise community awareness with regard to protection of the environment. For this purpose, they have created partnerships with different types of institutions, including educational partners. The campaign, "Forest month" is one such action for preserving the treasures of our little universe, such as the area of the city of Teiuş, a town located 19 km North-East of the city of Alba Iulia. It is bordered by the valley of the Mureş River on the East, which gently flows from the Trascău Mountains, situated Northwest of the aforementioned area. It is a place of sweet waters, flora and fauna protected by tree species such as poplar trees, willow trees, species of elderberry, oak trees, fir trees, etc. One day I decided together with the students I teach to engage in an activity for the afforestation of the area. We proceeded using the following steps: Information and curiosity We began with a viewing of a short film produced by the "Silvic Progress" association regarding the mutual relationships between water and the forest, flora and fauna. We identified the benefits of water, which is rich in minerals for the trees and plants of the Apuseni Mountains. Keeping water in the vicinity of the roots requires removing weeds, without increasing evaporation or triggering soil erosion. Each species of trees have a different way of absorbing water from the environment. Annual evaporation depends on the species as well, with the spruce having the greatest

    In 1968, excavations in the Climente II cave in the Iron Gates gorge of the River Danube in southwest Romania unearthed the skeleton of an adult male. The burial was assumed to be of Late Pleistocene age because of the presence of Late Upper Palaeolithic (LUP) artefacts in the cave. However, there was no strong supporting stratigraphic evidence, and the body position is reminiscent of Early Neolithic burial practice in the region. Here, we report the results of radiocarbon and stable isotope analyses of the Climente II skeleton, which show that the skeleton dates to the Bølling-Allerød Interstadial ~14,500 cal BP. This is several millennia older than any previously dated human remains from the Iron Gates region and confirms its status as the oldest known burial from Romania. The stable isotope results indicate a diet with an emphasis on aquatic resources, contrary to the commonly held view that the LUP inhabitants of the Iron Gates subsisted mainly by hunting large land mammals.

    According to the World Health Organization and Stop TB Partnership, tuberculosis among children often remains undiagnosed, the main reported causes being lack of access to health services or because health professionals unrecognizing the signs and symptoms of tuberculosis in this age group. In Romania, consistent with TB endemic levels, the overall incidence progressively decreased from 142.2%ooo in 2002 to 82.8%ooo in 2011, incidence of TB in children 0-14 years dropped steadily from 47.2 %ooo (1784 cases) in the same "peak year"2002 to 23.6% ooo (766 cases) in 2011. The distribution of TB disease in children by counties shows variations between these, the explanations may be related both to differences in offer of the bacilli between different areas (prevalence of pulmonary patients smear and/or culture positive) and by deficiencies in the detection of cases and lack of rigor in diagnosis (variation in the incidence of TB in 0-14 years from 2.S%ooo in Sălaj county up to 53.2%ooo in Maramures county in 2011). The number of serious cases of TB in children (meningoencephalitis, miliary, cavitary) still maintains a constant high annual rate (65 cases in 2011), which demonstrates the severity of endemic TB in our country. Prompt assurance of TB diagnostic and also the accurate management of TB treatment constitute the guarantee of the decrease of this disease, goal applies to all age groups.

    In Romania, the communist planned economy system was in place for 42 years but ended due to a revolution in 1989. An environmental administration was started 1990. In order to assist with environment related activities, one of the authors worked in Bucharest for two years from March 2002 to March 2004 as a JICA (Japan International Cooperation Activity) member. One of the most important problems regarding environmental protection in Romania is waste management. In Japan, the regulations and penalties system of waste management have been used for a long time. However, there are many serious problems with the system, such as a decrease in waste disposal facilities and illegally disposed waste. The authors studied a new plan that uses a certification system in order to promote recycling industries. This system is both efficient and inexpensive so it is possible that this method of waste management could be transmitted to Romania.

    Endometrial cancer represents the most frequent gynecological malignant affection in the developed countries, in which the incidence of cervical cancer has significantly decreased due to the rigorous application of screening methods and prophylaxis. According to its frequency, endometrial cancer is situated on the fourth place in the category of women's genital-mammary malignant diseases, after breast, cervical and ovarian cancer in Romania. The incidence and mortality rates due to endometrial cancer have registered an increasing trend worldwide and also in Romania, a significant decrease of the age of appearance for the entire endometrial pathology sphere being noticed. At the national level, the maximum incidence is situated between 60 and 64 years old, the mortality rate of the women under 65 years old being high in Romania. The study evaluates endometrial cancer, from an epidemiologic point of view, at the national level compared to the international statistic data.

    Dermacentor reticulatus (Fabricius, 1794), also known as the marsh tick or ornate dog tick is the second most significant vector (next to Ixodes ricinus) of protozoan, rickettsial and viral pathogens in Europe. Until now, only limited information on the distribution of D. reticulatus in Romania is available. A study was conducted on the distribution of D. reticulatus in Romania during 2012-2014. In this study, D. reticulatus was detected in 17 counties, in 14 of which the species was recorded for the first time. Tick activity was evident throughout the year, except during July and August. Additionally, D. reticulatus was recorded for the first time in Romania from wild boar, foxes and humans. These data suggest that this tick species has a broader geographic range and may have more veterinary and medical importance than previously known.

    Latest climate changes in Romania :tornadoes As climate change has been considered a research priority in the European Strategy for enduring development , I have done a detailed research with my students of the new climate change that has been going on in Romania for the past decade. More precisely I have studied together with my students the phenomenon of tornadoes that have seriously affected on some occasions some our our country's locations, such as Facaeni, in the county of Ialomita, in August 2002. A quite unusual phenomenon occurred on that location situated at 44.56 degrees northern latitude and at 27.89 degrees eastern longitude, that caused severe damage to the local environment and three persons lost their lives in the process, as well as other thirty people suffering from bad injuries. The magnitude of that strong phenomenon rose on the Fujita scale at level F3 which implied wing gusts between 252-300 km/ hour . A main cause of occurrence of such a severe weather was the difference in temperature of two huge air masses, one of Polar origin, and other coming from tropical latitudes . Their crossroads was on that precise territory of Romania. The duration of the worst part of the tornado path lasted only for two minutes, but the consequences of its passage were colossal : total destruction of 33 households, and other 395 were partially damaged, 1,000 people afflicted by the devastation and 100 acres of acacia tree forest ripped off the ground. The first ever recorded tornado phenomenon in Romania was around 1894-1896, considered at that time " a freak of nature" was seen as a cloud formation abnormality , an uncontrolled force of nature that had a huge impact , and at the same time, it vanished into "thin air " fast. The most affected areas in Romania by tornadoes are the south-eastern planes where the cloud formations can create fast columns of air rotating up to 500 km/hour. The local people compared the cloud funnels created on the planes to "serpents

    Infections by the protozoan parasite Toxoplasma gondii are widely prevalent in humans and other animals worldwide. However, information from eastern European countries is sketchy. In many eastern European countries, including Romania, it has been assumed that chronic T. gondii infection is a common cause of infertility and abortion. For this reason, many women in Romania with these problems were needlessly tested for T. gondii infection. Most papers on toxoplasmosis in Romania were published in Romanian in local journals and often not available to scientists in other countries. Currently, the rate of congenital infection in Romania is largely unknown. In addition, there is little information on genetic characteristics of T. gondii or prevalence in animals and humans in Romania. In the present paper we review prevalence, clinical spectrum and epidemiology of T. gondii in humans and animals in Romania. This knowledge should be useful to biologists, public health workers, veterinarians and physicians.

    Abstract The reptile fauna of Romania comprises 23 species, out of which 12 species reach here the limit of their geographic range. We compiled and updated a national database of the reptile species occurrences from a variety of sources including our own field surveys, personal communication from specialists, museum collections and the scientific literature. The occurrence records were georeferenced and stored in a geodatabase for additional analysis of their spatial patterns. The spatial analysis revealed a biased sampling effort concentrated in various protected areas, and deficient in the vast agricultural areas of the southern part of Romania. The patterns of species richness showed a higher number of species in the warmer and drier regions, and a relatively low number of species in the rest of the country. Our database provides a starting point for further analyses, and represents a reliable tool for drafting conservation plans. PMID:24146598

    Toxoplasma gondii is an obligate intracellular parasite that most commonly causes asymptomatic infection in immunocompetent hosts, but can have devastating consequences in congenitally infected infants and immunocompromised patients. We evaluated the seroprevalence of T. gondii in the general population in Western Romania. Sera from 304 individuals were analysed with the Pastorex Toxo test, which allows the simultaneous detection of T. gondii IgG and/or IgM antibodies. T. gondii antibodies were demonstrated in 197 individuals (64.8%) and the prevalence increased with age: 35.0% in those < 20 years versus 76.8% in those ≥ 70 years (p < 0.001). There was a higher prevalence of T. gondii antibodies in rural areas (76.9%) than in urban regions (55.3%) (p < 0.001). Our results suggest a high prevalence of T. gondii antibodies in Western Romania.

    Although cases of Mediterranean spotted fever (MSF) have been reported for decades in southeastern Romania, there are few published data. We retrospectively studied 339 patients, diagnosed with MSF at the National Institute of Infectious Diseases "Prof. Dr. Matei Bals" between 2000 and 2011, in order to raise awareness about MSF in certain regions of Romania. According to the Raoult diagnostic criteria 171 (50.4%) had a score >25 points. Mean age was 52.5 years. One hundred and fifty-five (90.6%) patients were from Bucharest and the surrounding region. Almost all patients presented with fever (99.4%) and rash (98.2%), and 57.9% had evidence of a tick bite. There were no recorded deaths. Serologic diagnosis was made by indirect immunofluorescence assay. Of the 171 patients, serology results for R. conorii were available in 147. One hundred and twenty-three (83.7%) of them had a titer IgG ≥1:160 or a fourfold increase in titer in paired samples. MSF is endemic in southeastern Romania and should be considered in patients with fever and rash even in the absence of recognized tick exposure. Since the disease is prevalent in areas highly frequented by tourists, travel-associated MSF should be suspected in patients with characteristic symptoms returning from the endemic area.

    Romania has entered a period of rapid and dramatic population aging. Older Romanians are expected to make up more than 30% of the total population by 2050. Yet, gerontological research is sparse and the few studies of older Romanians that exist are not well used by policy makers. Much of the research is descriptive and focused on needs assessments. Most databases created from studies of older adults are not available for secondary analysis, nor is Romania among the countries included in the Survey of Health and Retirement in Europe. The pension and health insurance systems and the system of social welfare services address the specific needs of older Romanians, but comparing the social protection systems in the European Union with those in Romania suggests the existence of a development lag. The relevant legislation exists but there are still issues regarding the implementation of specially developed social services for older persons. As a result, there are major inadequacies in the organization of the social service system: too few public services, insufficient budget funds, insufficient collaboration between public and private services, and frequently overlapping services.

The design concept was to transport the mining waste away from the city, while the gold and silver in the tailings could be recovered, using efficient and modern technology that was not available at the time the dam was established. On 30 January, 2000, at 22.00, the dam burst and released 100,000 cubic meters of tailing pulp, heavily contaminated with cyanide and cyanide complexes, especially with copper, into the Lapus and Somes tributaries of the river Tisa.

    Aims to highlight the changes occurred in the evolution of the fertility phenomenon in Romania, focusing on developments in the general fertility rate, total fertility rate, number of live births, and on the construction of specific indicators to reveal the source of demographic change. Several theories on the factors that may cause fertility decline it were outlined, underlining the presence of these factors during fertility dynamics in our country. After 1990, population decline may be explained by a close inter-relationship between economic theories (worsening economic conditions lead to decreased fertility) and the second demographic transition (postponement of births, fertility change model).

    ESERO Romania (The European Space Education Resource Office - Romania) has been established in 2014 as a collaboration between the Europen Space Agency and the Romanian Space Agency. The key aim of ESERO Romania is to increase STEM literacy in Romania by using space as an appealing context to make the teaching and learning of Science, Technology, Engineering and Math subjects more attractive and accessible. In Romania, the Office intends to bridge the gap between the prize-winning elites and the scientifically illiterate mass through the training of teachers, through raising awareness of space activities and through the dissemination of materials, making full use of ESA’s literature and logistical support in this process. The Romanian ESERO is also serving as the main interface between ESA Education and the Romanian educational community. The ultimate aim is to assure the formation of a future work force active in the space and engineering fields - including astronomy. This paper will outline the ways in which ESERO Romania contributes to space and astronomy education in Romania, as well as the challenges and opportunities encountered during the first year of its existence.

    Stanca-Costesti Reservoir holds the largest amount of water among reservoirs located in Romania and has multiple purposes, such as flood mitigation, hydropower production, irrigation etc. Our bathymetric survey was conducted along longitudinal, as well as transverse alignments, so as to cover the entire lacustrine surface by using an echo sounder. Data from three different surveys were employed, i.e. topographical (dating back to 1977, before the onset of flooding) and bathymetrical (1986 and 2000) surveys. The drainage basin of this reservoir extends accross three countries, Romania, Ukraine and Republic of Moldova, and whereas the mountain sector of the basin is mostly covered by forest, the lowland (the Moldavian Plateau) is used for agriculture, i.e., cereal crops. Thus, deforestation and inappropriate tillage techniques employed within this basin result in increased soil erosion. Most of the sediment load is carried during flood events, which have grown increasingly common, particularly in summer. The terraces formed along the downstream sector of the reservoir are not covered by alluvium, whereas the corresponding terraces from its upper sector have been covered by submerged glacises. Moreover, in the area of Ciugur river mouth we observed a submerged valley, as well as several submerged natural levees. The deepest area of the reservoir (29.2 m) is located adjacent to the dam and is thought to be the outcome of a circular current generated by the lake bottom morphology. The silting degree is rather high, ranging up to an index value of 7.3% over 33 years.

    Using data provided by the Self-Directed Search (SDS) on a sample of 1,519 participants comprising 3 subsamples containing high school students, university students, and working adults, the authors examine the structure of vocational interests in Romania. Three competing structural models of vocational interests (Holland's circumplex model and Gati's and Rounds and Tracey's hierarchical models) are analyzed with 3 different approaches: (a) frequency analysis of 2-letter codes, (b) randomization test of hypothesized order relations, and (c) structural equation modeling. The stability of the structure of vocational interests across age is also analyzed. The findings suggest mixed evidence for the 3 models, with Holland's model receiving more support from structural equation modeling, and Gati's and Rounds and Tracey's models receiving more support from the frequency analysis of 2-letter codes. The data conclusively show that the structure of vocational interests becomes clearer with age.

    We report on an interdisciplinary study focused on investigation of pottery fragments collected from the foundation of the wall of protohistoric site La Cetate, Bazdana village, Romania, close to the river Danube, dated towards the end of fourth century BC. The occurrence of pottery pieces under walls of that times is related to the foundation ritual. The samples were analysed by scanning electron microscopy (SEM) coupled with energy dispersive X-ray (EDX) spectroscopy, thermal analysis, X-ray diffraction (XRD) Fourier transform infrared (FTIR) and electron paramagnetic resonance (EPR) spectroscopies. The characterization of the samples includes chemical composition and microstructural properties imposed by processing conditions. They are slightly calcareous ceramic matrices. The identified crystalline phases are preponderantly quartz, with plagioclase, mica, wollastonite and magnetite. The results indicate that the possible firing temperature in air could be above 1100 °C, or lower - if the artisans used reducing atmosphere, that is impressive for that times.

    Natural hazards such as landslides, meandering and flash floods have caused economical damage and environmental changes in the last period of time increasing the risk level of the built-up areas and roads from Romania. Thus, an essential role in the prevention of negative effects and the identification of natural risks is played by the generation of hazard and risk maps. The purpose of the study is represented by the generation of multi-hazard and multi-risk maps using GIS technologies, which requires the identification of cumulated risk for each administrative-territorial unit situated in the study area of Niraj river basin from Transylvania Depression, Romania. The first stage in this approach was to develop the flood risk zonation which is based on floodable stripes, obtained using statistical analysis of past data series and their integration in determinist spatial analysis models, generated as a product of temporal flood probability and vulnerability of the territory. The probability of landslide occurrence was estimated using bivariate statistical analysis, by evaluating the importance of each class of preparatory factors depending of the characteristic/local conditions: lithology, geomorphology, structure, hydro-climatic factors, hydrogeology, seismicity, forestry and anthropogenic factor. Finally, the assessment of the risk associated to lateral river erosion, or meandering, was obtained by using the largest time span available (of the last 102 years) in order to identify the river's present dynamic trends of each river meander. The average and the maximum rate of erosion values were used to determine the meandering potential and to identify the meandering risk zones. Therefore, in order to accurately identify the local risk level, we calculated the spatial and temporal probability of occurrence of potential damaging events, as well as the distribution of the elements at risk based on their characteristic vulnerability. The final results represent valuable

    The author participates to the World Housing Encyclopedia project (www.world-housing.net), an internet based database of housing buildings in earthquake prone areas of the world. This is a voluntary project run by the Earthquake Engineering Research Institute, Oakland, California and the International Association of Earthquake Engineering, financial means being available only for the website where the information is shared. For broader dissemination in 2004 a summary publication of the reports to date was published. The database can be querried for various parameters and browsed after geographic distribution. Participation is open to any housing experts. Between 2003 and 2006 the author was also member of the editorial board. The author contributed numerous reports about building types in Romania, and each one about building types in Germany and Switzerland. This presentation will be about the contributed reports on building types in Romania. To the Encyclopedia eight reports on building types from Bucharest were contributed, while in further research of the author one more was similarly described regarding the vulnerability and the seismic retrofit. The selection of these types was done considering the historic development of the built substance in Bucharest from 1850 on, time from which a representative amount of housing buildings which can be classified in typologies can be found in Bucharest. While the structural types are not necessarily characteristic for the style, since the style has other time limits, often appearing before the type became common and then remaining being practiced also after another style gained ground, a historic succession can be seen also in this case. The nine types considered can be grouped in seven time categories: - the time 1850-1880, for a vernacular housing type with masonry load bearing walls and timber floors, - the time 1880-1920, for the type of two storey or multi-storey house with masonry walls and timber floors (in which

  14. E-health progresses in Romania.

    The paper is presenting the recent evolution of e-health aspects in Romania. Data presented are based on governmental reports. Surveys organized by the "Lucian Blaga" University of Sibiu and studies carried on by the national Institute for Research and Development in Informatics (I.C.I.) have shown that Romania has important health problems, from cardio vascular diseases (CVD) to cancer and infectious diseases, a high score on mortality and morbidity and a low one on natality. Poor management of the health sector did not help to solve all these problems. In the last 14 years there were several attempts to reform healthcare but none succeeded until now. The health insurance system is operational but needs still to be improved. Acknowledging the deep crisis of the health system the Prime Minister nominated a new minister of health and important changes in the health management approach are to be envisaged. One of this is the introduction of the e-procurement system for all health related goods. In spite of the crisis of the health system, e-health applications are flourishing. We can distinguish applications at national and local level and also punctual applications. The main applications refer to hospital information systems (HIS), electronic health records (EHR), e-procurement, image processing, diagnosis and treatment aids, telediagnosis, teleconsultation, education, research and domain oriented web support services. Most academic clinical hospital is now members of a web community "mednet". Unfortunately a lot of medical web sites have disappeared for lack of funds. As the health sector is in general funded from the public budget and the health crisis is deepened in the last years, the driving force in implementing e-health concepts and technologies is not the Ministry of Health but the Information Technology (IT) community, with a strong support from the Ministry of Information Technology and Communications and also from the Ministry of Education and Research

    Soils contamination with heavy metals is one of the most severe aspects of environmental pollution in Romania, independently of the origin sources (domestic or industrial activities) or type of disposal (organised landfill or hazardous deposits)[l-2]. This fact is the consequence of the poor state of the existing waste deposits in Romania and of the significant costs involved by the establishing of a new landfill according with the international regulations. The present study is trying to emphasise the contamination of soils surrounding different categories of waste deposits (sewage sludge ponds, domestic and industrial waste landfills, hillocks, sterile deposits) from various regions of Romania. Some case studies show a special interest being localise in a protected area (Iron Gates Natural Park). In order to quantify the concentration of metals like Cd, Cr, Cu, Pb, Zn, Ni, Mo in soil samples, analysis were performed using Inductively Coupled Plasma - Optical Emission Spectrometry (ICP-OES). Romanian standards were used as reference values[3].

    The revision of Romanian earthquakes shows a distribution suggesting a sinking lithosphere under the Carpathian arc. Thermal and gravitational anomalies, as well as petrological and tectonic features, provide further evidence on the cause and character of intermediate earthquakes of Romania. This is consistent with the theory of plate tectonics in south-east Europe.

    The need to use early warning methods to reduce natural risks in modern societies is related to their unprecedented dependence upon technology. The strong deep events originating from Vrancea-Romania (Mw =7.5) area and shallow events originating from Banat-Romania or Shabla-Bulgaria areas can generate destructive effects in Romania and neighbor countries, and may seriously affect high risk manmade structures. EWS for deep Vrancea earthquakes uses the time interval (28-32 sec.) between the moment when the earthquake is detected by the local seismic network installed in the epicenter area (Vrancea) and the arrival time of the seismic waves in the protected area (Bucharest) to send earthquake warning to users. For the shallow events several methodologies to rapidly estimate earthquake magnitude are under testing. NIEP developed an early warning system that is able to evaluate rapidly earthquake magnitude after detection in the epicenter. In the last years, NIEP upgraded its seismic network in order to cover better the seismic zones of Romania. The early warning system consists of seismic stations that allow rapid communication of data, several software modules developed at NIEP and a communication network. The system allows estimation of earthquake magnitude and permits to send earthquake alarm very fast to users. The early warning software modules minimize communication latencies present in other communication protocols in order to have a rapid magnitude determination. This software was developed by NIEP and is running in present at our institute in real time.

    The subfossil wood material collected along rivers from north-eastern part of Romania was dated with radiocarbon and dendrochronological investigated. The study area is represented by Siret and Moldova rivers. Both rivers originate in the Eastern Carpathians where they collect the majority of their tributaries, further crossing through the eastern sector of the mountains by creating transverse valleys. Along these rivers, on reaches covering lengths of 100 km and 140 km, tree-rings samples were collected (n = 40 along Moldova River and n = 37 along Siret River). Of the total number of 77 collected wood samples, we dated 26 in order to determine the absolute age. The species of subfossil trunks belong to Quercus (n=51), Ulmus (n=20) and Alnus genus (n=3). The ratio between the average growth and the trunk age varies greatly, from trees aged as little as 38 years with average diameters above 32 cm, to trees as old as 184 years with diameters of just 45 cm. The absolute age of subfossil trunks varied from few decades to 6900-6670 cal yrs BP. The obtained result consists in dendrochronological series which covers periods from Mid to Late Holocene. The highest concentration of deposited subfossil trunks was carried out in the last 3000 yrs BP. Therefore, it is possible to create an exclusively dendrochronological sequence for this time frame. A first step in this direction is the extension of living tree rings series (180 yrs.) with modern wood in order to create an enlarged series of 383 years, (as illustrated for rings series of modern oaks in Dolhasca site, Siret Valley). Albeit there are many gaps in the reconstruction of these phases, several clusters are easily distinguishable, i.e. 3500-2900 years BP, 2200-2075 years BP, and 1000-800 years BP extending to LIA. By relating this data to obtained information from other proxies (lacustrine sediments, pollen records, lake levels, etc) we may conclude that the two major periods in Holocene history were characterized by

    1991-12-31

    The 14-MW TRIGA steady state reactor (SSR) located in Pitesti, Romania, first went critical in the fall of 1979. Initially, the core configuration for full power operation used 29 fuel clusters each containing a 5 {times} 5 square array of HEU (10 wt%) -- ZrH -- Er (2.8 wt%) fuel-moderator rods (1.295 cm o.d.) clad in Incology. With a total inventory of 35 HEU fuel clusters, burnup considerations required a gradual expansion of the core from 29 to 32 and finally to 35 clusters before the reactor was shut down because of insufficient excess reactivity. At this time each of the original 29 fuel clusters had an overage {sup 235}U burnup in the range from 50 to 62%. Because of the US policy regarding the export of highly enriched uranium, fresh HEU TRIGA replacement fuel is not available. After a number of safety-related measurements, the SSR is expected to resume full power operation in the near future using a mixed core containing five LEU TRIGA clusters of the same geometry as the original fuel but with fuel-moderator rods containing 45 wt% U (19.7% {sup 235}U enrichment) and 1.1 wt% Er. Rods for 14 additional LEU fuel clusters will be fabricated by General Atomics. In support of the SSR mixed core operation numerous neutronic calculations have been performed. This paper presents some of the results of those calculations.

  8. The challenges of tobacco control in Romania. Policy review.

    Loubeau, Patricia R

    2013-06-01

    This article investigates elements of tobacco control issues in Romania. Using European Union requirements for tobacco control legislation as a backdrop, it examines the key issues of smuggling, taxation, and unemployment in a transitional economy. Romania has made some progress by adding text and pictorial warnings to cigarette packages and offering comprehensive help to quit smoking. Using empirical examples, it is argued that more progress in tobacco control is needed in the area of increased taxation, enforcement of non-smoking bans, and new legislation requiring advertising bans at point of sale, kiosks, and billboards. This article draws wider public attention to the problems that smuggling and taxation present for tobacco control, helps identify other countries confronting similar issues, and stimulates effective interventions.

  9. The "social case": Illness, psychiatry, and deinstitutionalization in postsocialist Romania.

    PubMed

    Friedman, Jack R

    2009-12-01

    In this article, I examine the use of an ad hoc medical category--the "social case"--by psychiatrists in contemporary Romania. "Social cases" receive intensive psychiatric care, usually through long institutional stays, remaining hospitalized because psychiatrists perceive them as too poor and, thus, "unfit" to survive without the welfare assistance provided by institutionalization. The "social case" label emerges at the intersection of (1) plans by the state to deinstitutionalize public mental health care, (2) the rise of a new class of downwardly mobile and increasingly poor formerly working-class people, and (3) the desire of psychiatrists to protect their patients in the face of neoliberal assaults on Romanian welfare state support for publicly funded mental health care. Disability status, illness categories, and everyday medical practices have become battlegrounds for struggles over medical understandings of the psychological distress and illnesses that grip what I call the "New Poor" in postsocialist Romania.

    Satellite-based measurements of atmospheric trace gases loading give a realistic image of atmospheric pollution at global, regional, and urban level. The aim of this paper is to investigate the trend of atmospheric NO2 content over Romania for the period 1996–2010 for several regions which are generally characterized by different pollutant loadings, resulting from GOME-1, SCIAMACHY, OMI, and GOME-2 instruments. Satellite results are then compared with ground-based in situ measurements made in industrial and relatively clean areas of one major city in Romania. This twofold approach will help in estimating whether the trend of NO2 obtained by means of data satellite retrievals can be connected with the evolution of national industry and transportation.

Data were collected through a school-based survey. Findings indicated that higher levels of economic pressure were associated with higher levels of marital conflict. Economic pressure was also associated with higher marital conflict indirectly through increased maternal depression and lowered social support. The present results were similar to those obtained in studies conducted among U.S. samples.

    Granulocytic anaplasmosis is a common vector-borne disease of humans and animals with natural transmission cycle that involves tick vectors, among which Ixodes ricinus is the most important. The present paper reports the prevalence and geographical distribution of A. phagocytophilum in 10,438 questing Ixodes ricinus ticks collected at 113 locations from 40 counties of Romania. The unfed ticks were examined for the presence of A. phagocytophilum by PCR targeting a portion of ankA gene. The overall prevalence of infection was 3.42%, with local prevalences ranging between 0.29% and 22.45%, with an average prevalence of 5.39% in the infected localities. The infection with A. phagocytophilum was detected in 72 out of 113 localities and in 34 out of 40 counties. The highest prevalence was recorded in females followed by males and nymphs. The results and the distribution model have shown a large distribution of A. phagocytophilum, covering Romania's entire territory. This study is the first large scale survey of the presence of A. phagocytophilum in questing I. ricinus ticks from Romania.

    A prototype early warning system was developed in Romania in order to provide 25-35 seconds warning time for Bucharest facilities for earthquake with M >6.5. The prototype system consists of four components: network ground motion sensors in the epicentral area, an area centre in epicentre, a digital radio communication link and a central data centre. These components are fully functional at Romania seismic data centre (RO_NDC) in Bucharest since August 2003. The system is in testing phase for one important user from Bucharest the Van de Graff Accelerator were we provide about 25 seconds warning time before shaking occurs. Because the prototype system demonstrated that potentially useful warnings of strong shaking from Vrancea earthquakes are feasible, the National Institute for Earth Physics decide to implement this system for other four important facilities from Romania. At every user was installed a dedicate device which is able to stop trigger the specific safety rules for each facility. The system was tested only with offline earthquakes due to the fact that since August 2003 there was no strong earthquake such that the real time detection algorithm to issue an alarm. The detection algorithm is based on a combination of spectral and amplitude analysis for the first 4 seconds of the P wave.

    In the post-communist period the term "deforestation" becomes well known in Romania. By the middle of 19th-century more than 27% of the country was covered by forests, but since then certain changes took place in this respect. The study of the phenomena can be done by the help of maps. In this regard it is very important to have old maps which can emphasize the situation from the past. As the map of Southern Romania, made about Walachia in 1864, called Charta României Meridionale is now georeferenced and accessible on the web, it can be used as a basis for such studies. Researchers are now able to make quantitative studies. In our poster we made a study of two different regions from Southern Romania: one from a mountain region and one from a plain region. Both are in the basin of Argeş river, tributary of Danube. The mountain region lies in the upper basin of Argeş river which is now occupied Vidraru artificial lake. The plain region lies on wetland and today is a natural reserve. The study regions have almost the same size (about 400 km2). In order to follow the evolution in time of the forest cover we used four data sources which covers a period of more than 150 years: Charta României Meridionale (the survey was made between 1855 and 1859); Lambert-Cholesky maps (the survey was made at the end of the 19th century); Gauss-Krüger maps (from the 1960s) and orthophotographs made in 2005. All these materials are georeferenced. With the help of GIS software we digitized the areas covered by forests in both regions. The areas were determined and compared. Using GIS techniques we can overlap the areas covered by forests, the illustrations were made this way. As a conclusion we can say that the plain region suffered important changes as the natural landscape turns into an agricultural-human landscape in the first part of the 20th century. We can say that the actual forest is preserved only because now it is a protected area. In the mountain region the territory was

    2015-04-01

    Keywords: methane, greenhouse gases, geogenic emissions, Romania Relatively often, the hydrocarbon reservoirs are not completely sealed, thus permitting the channeling to the surface of various amounts of gas, mainly consisting of methane and homologues. When important volumes of gas are released, features as mud volcanoes and everlasting fires may occur. When the gas amount is low, the degassing can be revealed by instrumental means only. The gas seeps may be useful as indicators in the hydrocarbon exploration, but may be also hazardous when gas is accumulating in closed spaces. Additionally, the geogenic methane degassing represents an important contribution to the atmospheric budget of greenhouse gases. Romania is one of the European important hydrocarbon producers, with oil and gas deposits in different geologic and tectonic contexts. As well, the frequency of gas emitting features and seepage areas is high. Some relevant hydrocarbon-prone areas from Romania, namely the Neogene Transylvanian Basin, the Carpathian Foredeep, and the Moldavian Platform, are comparatively analysed within the current work from the point of view of methane emissions. The Carpathian Foredeep hosts the most impressive mud volcanoes and everlasting fires in Romania, classified among the biggest in Europe. The degassing area also extends in the Carpathian Flysch zone. The Transylvanian Basin hosts numerous gas-bearing structures, mainly of biogenic origin. With some exceptions, the methane-emitting features are small, releasing relatively low amounts of gas. A relatively high number of seeps have been described on the Moldavian Platform, although no commercial hydrocarbon reservoirs have been identified. The seeps are small, and they are releasing low amounts of methane. However, it is important to notice that the investigated zone partly corresponds to an area of interest for shale gas, related to the deep-seated Silurian shales. For all mentioned areas, the main geochemical

    Băiţa-Ştei mine is an open pit mine in NW Romania (West Carpathian Mountains). It was the largest surface uranium deposit in the world. Two means of uranium transport and dissemination were used over time. The first was the natural way, represented by transportation of geological sediments by Crişul-Băiţa River that crosses the Băiţa surface deposit. These sediments were used as building materials (stone, gravel, sand). The second way was related to the people living in this valley, who used also the uranium waste as building material. The preliminary indoor radon concentrations measured in the buildings ranged from 40 to 4000 Bq m-3 with a mean value of 241 Bq m-3. A focused radon survey facilitated the selection of 20 houses with the highest indoor radon that were therefore proposed for remediation. To find the radon sources of these houses, systematic investigations on radon were performed. The remedial measures for these 20 houses were tested on a chosen pilot house.

    The development of neurosurgery as an independent specialty took place with great difficulty in Romania. In this respect, the most revered personalities are those of Professor Alexandru Moruzzi (1900-1957) (in Iasi) and Professor Dimitrie Bagdasar (1893-1946) (in Bucharest), who are the fathers of modern neurosurgery in Romania. Professor Bagdasar was schooled in Professor Harvey Cushing's clinic in Boston and is credited with creating the first completely independent neurosurgical unit in Romania. His legacy was carried on with honor by Professor Constantin Arseni (1912-1994), who, in 1975, tasked Dr. Lenke Horvath (1917-1991) with creating the first autonomous pediatric neurosurgery unit in Bucharest. This article is a small tribute to the founder of pediatric neurosurgery in Romania and one of the female pioneer neurosurgeons, who, by personal example of dedication and hard work, radically changed medical thinking and neurosurgery in Romania.

    The collapse of socialism in 1989 triggered a phase of institutional restructuring in Central and Eastern Europe. Several countries chose to privatize forests or to return them to pre-socialist owners. Here, we assess the implications of forest restitution on the terrestrial carbon balance. New forest owners have strong incentives to immediately clearcut their forests, resulting in increased terrestrial emissions. On the other hand, logging generally decreased after 1989 and forests are expanding on unused or abandoned farmland, both of which may offset increased logging on restituted forests. We mapped changes in forest cover for the entire country of Romania using Landsat satellite images from 1990 to 2010. We use our satellite estimates, together with historic data on logging rates and changes in forest cover, to parameterize a carbon book-keeping model for estimating the terrestrial carbon flux (above and below ground) as a consequence of land use change and forest harvest. High logging rates during socialism resulted in substantial terrestrial carbon emissions and Romania was a net carbon source until the 1980s. After the collapse of the Soviet Union forest harvest rates decreased dramatically, but since restitution laws were implemented they have increased by 60% (from 15 122 ± 5397 ha y - 1 in 2000 to 23 884 ± 11 510 ha y - 1 in 2010), but still remain lower than prior to 1989. Romania currently remains a terrestrial carbon sink, offsetting 7.6% ± 2.5% of anthropogenic carbon emissions. A further increase in logging could result in net emissions from terrestrial ecosystems during the coming decades. However, forest expansion on degraded land and abandoned farmland offers great potential for carbon sequestration.

    In 2007, Romania, the largest southeastern European country, reported the highest notification rate of botulism cases in the European Union (0.18 per 100,000 inhabitants), which was 18 times higher than the reported rate in the United States (0.01 per 100,000 inhabitants). This report aims to analyze published and unpublished surveillance data on foodborne botulism in Romania from 1980 to 2009 in the context of political and economical changes that occurred in the former communist countries. The mean annual incidence rate of botulism cases was significantly lower during the late communist period, 1980-1989 (0.06±0.03 cases per 100,000 inhabitants), than during the years 1990-1999 (0.1±0.04 cases per 100,000 inhabitants, p=0.01) and 2000-2009 (0.12±0.04 cases per 100,000 inhabitants, p<0.01). The highest incidence rates were registered in 1998 and 2007 (0.18 cases per 100,000 inhabitants), whereas the lowest incidence rate was registered in 1983 (0.02 cases per 100,000 inhabitants). The disease was usually associated with the consumption of home prepared meat products (mainly raw sausages, smoked-dried meat). Most of the laboratory-confirmed cases tested positive for type B toxin (99%). During 2007-2009, the incidence was particularly high in northwestern and western Romania (0.5 and 0.3 cases per 100,000 inhabitants, respectively). The fatality rate was 60% before 1995 and decreased to 12.2±8.5% during 1999-2009. The general ascending trend of infection rates throughout the period studied demonstrates the need for the implementation of correct public health and educational measures to fully prevent this severe disease.

    EWS for Vrancea earthquakes uses the time interval (28-32 sec.) between the moment when the earthquake is detected by the local seismic network installed in the epicenter area (Vrancea) and the arrival time of the seismic waves in the protected area (Bucharest) to send earthquake warning to users. In the last years, National Institute for Earth Physics (NIEP) upgraded its seismic network in order to cover better the seismic zones of Romania. Currently the National Institute for Earth Physics (NIEP) operates a real-time seismic network designed to monitor the seismic activity on the Romania territory, dominated by the Vrancea intermediate-depth (60-200 km) earthquakes. The NIEP real-time network consists of 102 stations and two seismic arrays equipped with different high quality digitizers (Kinemetrics K2, Quanterra Q330, Quanterra Q330HR, PS6-26, Basalt), broadband and short period seismometers (CMG3ESP, CMG40T, KS2000, KS54000, KS2000, CMG3T,STS2, SH-1, S13, Ranger, gs21, Mark l22) and acceleration sensors (Episensor). Recent improvement of the seismic network and real-time communication technologies allows implementation of a nation-wide EEWS for Vrancea and other seismic sources from Romania. We present a regional approach to Earthquake Early Warning for Romania earthquakes. The regional approach is based on PRESTo (Probabilistic and Evolutionary early warning SysTem) software platform: PRESTo processes in real-time three channel acceleration data streams: once the P-waves arrival have been detected, it provides earthquake location and magnitude estimations, and peak ground motion predictions at target sites. PRESTo is currently implemented in real- time at National Institute for Earth Physics, Bucharest for several months in parallel with a secondary EEWS. The alert notification is issued only when both systems validate each other. Here we present the results obtained using offline earthquakes originating from Vrancea area together with several real

    This paper focuses on the regime of sediment transportation to the river mouth of a catchment of 206 km2, located on the easternmost side of the Eastern Carpathians (NE Romania). The primary aim of the paper is to attempt a quantification of the catchment controlling factors of the sediment volume transited through the drainage network and their annual and multi-annual distribution. Among these factors we will focus on the role of sediment sources and human interventions in the mobilization of sediments towards rivers. The data employed in this study were obtained from the Parhauti gauging station (1973 to 2014), located at a distance of about 1.7 km from the confluence of the Solonet River with the Suceava River. These are represented of measurements of water discharge, suspended sediment discharge (hourly or daily measurements during flash flood intervals) and monthly values. The data were correlated with records on rainfall, local slope and morphological characteristics of the river crosssection. For a more detailed analysis we introduced a further comparison with records obtained at other gauging stations, located within the same physical-geographical settings, in neighboring catchments. Regarding our study catchment, investigations were performed on all variables that control flow formation and sediment load of water flows, i.e. geologic substrate, landforms, catchment morphometry, characteristics of the drainage network, land use, types of human interventions in the catchment area and on the river network. The average drainage network density equals ca. 2.5 km / km2, ranging from less than 1 km / km2 at the watershed, to the maximum of over 4 km / km2 recorded at the cuesta frontslopes. The multi-annual average amount of suspended sediment transport is 3.06 kg / s. Suspended sediment transport occurs most intensely during summer (months VI-VIII), (59.8%) as a result of floods which enhance the power of the river. During winter months (XII-II), sediment

    Leishmaniasis is a parasitic infection caused by protozoans classified as Leishmania species. Romania is not considered an endemic country and there are only few reports of sporadic cases in the last 100 years. However, studies suggest that the disease is spreading north. We present the case of a 44 year old female that presented with asthenia, perspirations, vertigo, weight loss and menometrorhagias in small to medium quantity. Clinical exam revealed the presence of splenomegaly and her blood tests indicated she had pancitopenia; differential diagnosis included myeloproliferative or lymphoproliferative disorders, infections that evolve with spleen enlargement, autoimmune-related splenomegaly and hepatic--all tests were negative. She refused the bone marrow aspiration. Three months later, her condition worsened and the menometrorragias became more severe. Bone marrow aspiration revealed the presence of numerous intra and extracellular Leishmania spp. amastigotes. A detailed anamnesis showed that she had worked for six months in Italy as a care-giver nine months ago. She was transferred to Bucharest where she received optimal treatment. However, due to the continuous bleeding, the evolution was unfavourable. This is an alarm sign for physicians that should take into account the fact that, due to population migration and global warming, tropical infectious diseases are becoming more and more common. The signs and symptoms, as well as the treatment in leishmaniasis are reviewed, as well as a brief history of leishmaniasis in Romania.

    Intestinal parasitic diseases such as enterobiasis, giardiasis, and ascariasis are detected most frequently in Romania, but their importance is definitely surpassed by trichinellosis, cystic echinococcosis, and toxoplasmosis. Malaria was common until its eradication in 1963, and only imported cases are reported nowadays. The aim of this review was to bring together essential data on the epidemiology and history of human parasitoses in Romania. Information on 43 parasitic diseases was collected from numerous sources, most of them unavailable abroad or inaccessible to the international scientific community. Over time, Romanian people of all ages have paid a significant tribute to the pathogenic influences exerted by the parasites. Sanitary and socio-economical consequences of the parasites diseases have great negative impact on the quality of life of affected individuals and the overall well-being of the population. Implementation of efficient public health measures and informative campaigns for the masses as well as changing the inadequate habits that are deeply rooted in the population are mandatory for cutting successfully this Gordian knot.

    The oxygen and deuterium (δ18O and δD) isotopic composition of meteoric precipitation has been used as proxy to advance our understanding of past and present atmospheric circulation. Precipitation δ18O is a primary control on cave speleothem δ18O which is one of the main methods used to reconstruct past climatic variability on a variety of timescales. Here we present δ18O and δD in precipitation and cave drip waters from Urşilor Cave located in the Apuseni Mountains, western Romania in order to better understand the relationship between climate and speleothem δ18O at this site. Samples of weekly precipitation and cave drip water (4-day intervals) were collected between July 2010 and June 2011. In order to draw robust palaeoclimatic information from speleothems at Ursilor Cave we aim to establish the climatic controls on δ18O composition of precipitation in western Romania and determine the source of air masses delivering moisture at our site. Furthermore, we evaluate the extent to which any climatic signature is preserved in the drip waters from which the speleothem calcite precipitates.

    Fungal species and toxin contamination were determined in 110 cereal samples (54 maize, 35 wheat, and 21 barley) collected in the southeastern part of Romania from 2002 to 2004. The most frequent fungal contaminants belonged to Aspergillus and Fusarium, and maize was the most contaminated cereal. The main toxigenic species identified were Aspergillus flavus, Aspergillus fumigatus, Fusarium graminearum, and Fusarium culmorum in all cereals and Fusarium verticillioides in maize. The presence of aflatoxin B1 (AFB1), deoxynivalenol (DON), zearalenone (ZEA), fumonisins, and ochratoxin A was determined by enzyme-linked immunosorbent assay. More than 90% of the samples were contaminated with at least one toxin. Around 30% of maize samples were contaminated with AFB1, and in 20% of these samples the level of toxin exceeded that allowed by European Union regulations. In 48 and 42% of samples, levels of DON and ZEA, respectively, exceeded those allowed by the European Union. Neither fumonisins nor ochratoxin A were found in samples from any year or cereal. These results indicate that cereals produced in Romania have a particular pattern of mycoflora and mycotoxin contamination because DON and ZEA in addition to AFB1 were found.

    In the last decade, reducing urban pollution and improving quality of public spaces became a more and more important issue for public administration authorities in Romania. The paper describes the development of a web-GIS solution dedicated to monitoring of the green infrastructure in Bucharest, Romania. Thus, the system allows the urban residents (citizens) to collect themselves and directly report relevant information regarding the current status of the green infrastructure of the city. Consequently, the citizens become an active component of the decision-support process within the public administration. Besides the usual technical characteristics of such geo-information processing systems, due to the complex legal and organizational problems that arise in collecting information directly from the citizens, additional analysis was required concerning, for example, local government involvement, environmental protection agencies regulations or public entities requirements. Designing and implementing the whole information exchange process, based on the active interaction between the citizens and public administration bodies, required the use of the "citizen-sensor" concept deployed with GIS tools. The information collected and reported from the field is related to a lot of factors, which are not always limited to the city level, providing the possibility to consider the green infrastructure as a whole. The "citizen-request" web-GIS for green infrastructure monitoring solution is characterized by a very diverse urban information, due to the fact that the green infrastructure itself is conditioned by a lot of urban elements, such as urban infrastructures, urban infrastructure works and construction density.

    The study presents the validation of SMOS soil moisture satellite products for Romania. The validation was performed with in-situ measurements spatially distributed over the country and with in-situ measurements concentrated in on small area. For country level a number of 20 stations from the national meteorological observations network in Romania were selected. These stations have in-situ measurements for soil moisture in the first 5 cm of the soil surface. The stations are more or less distributed in one pixel of SMOS, but it has the advantage that covers almost all the country with a wide range of environmental conditions. Additionally 10 mobile soil moisture measurements stations were acquired and installed. These are spatially concentrated in one SMOS pixel in order to have a more detailed validation against the soil type, soil texture, land surface temperature and vegetation type inside one pixel. The results were compared and analyzed for each day, week, season, soil type, and soil texture and vegetation type. Minimum, maximum, mean and standard deviation were extracted and analyzed for each validation criteria and a hierarchy of those were performed. An upscaling method based on the relations between soil moisture, land surface temperature and vegetation indices was tested and implemented. The study was financed by the Romanian Space Agency within the framework of ASSIMO project http://assimo.meteoromania.ro.

    USE OF GIS TECHNOLOGY IN SURFACE WATER MONITORING FOR TARGETED POLICY INTERVENTION IN A MOUNTAINOUS CATCHMENT IN ROMANIA The collection of information on surface water quality is a specific activity that takes place systematically and regularly at regional and national scale, and it is important for the assessment of the water quality as well as for water management policy-making. A data base information management using a Geographical Information System (GIS) forms an important aspect of environmental management, which provides the frame for processing and visualisation of water monitoring data and information as well as for the optimisation of monitoring concepts. This paper presents an architecture performed by a GIS which provides a grafic database and attributes the nesessary measurements of the water quality to different sections of the mountainous catchment of the Suceava river in the north of Romania. With this approach the location of the water sampling points can be optimised in terms of the selection and setting of the river sections. To facilitate the setting of the sampling locations in the various sections of water sampling in the river, the presented GIS system provides to the user different information layers with combined or isolated data according to the objectives. In the frame of the research were created 5 layers of information in the basin under study, underlying the determination of a new information layer, namely the "Hydrografic Network Graded to Hydrographic Sections". Practically, in the studied basin were established 8 sections for water sampling locations, and the water quality characterization was done by the consideration of 15 quality indicators. The GIS system presented in this research is a valuable, useful and adaptable to land use changes data base that can be exploited by any number of combinations, its capabilities justify it's role as "tool to support decision making." With this characteristics it supports the policy-making of

    The drought is a complex phenomenon with slow manifestation which engages, depending on its duration and intensity, a number of different components of the climatic, hydrologic, pedologic systems. This paper investigates the relationships between drought and aridity on one hand and hydrological regime, on the other hand, in Bârlad river basin, in the eastern part of Romania. Recent studies have revealed that both meteorological and hydrological drought events have a significant frequency and magnitude in the area, so that an important impact on the hydrological regime is likely to occur. For the next decades, climate change scenarios estimate increasing temperatures and relatively low decreasing of precipitation. Therefore, eventual changes in the aridity characteristics can be expected, and they might have a considerable impact on the water supply or agriculture in the Bârlad catchment. The analysis covers the period 1961-2013 and it is based on monthly data from meteorological and hydrological stations. Seasonal indices were calculated for characterising the drought (SPI, SFI, PDSI, PHDI) and aridity (UNEP, de Martonne, Pinna), while their temporal variability was further investigated in relations with specific hydrological parameters (monthly discharge time series). The spatial distribution of the selected indices was analysed in the same context using co-variables integrated in a GIS framework. The results show that the hydrological drought is influenced and determined mostly by the meteorological drought. The highest variability between the aridity indices has been identified for the summer season, where the time lag between the hydrological response to the meteorological impulse is up to 2 months. The work has been financed by the research project Changes in climate extremes and associated impact in hydrological events in Romania (CLIMHYDEX), Cod PN II-ID-2011-2-0073, sponsored by the National Authority for Scientific Research.

    The present study sets out to determine the flood plains corresponding to flood discharges having 10, 50 and 100 year recurrence intervals on the Monoroštia, Petriš and Troaš Rivers, located in Western Romania, the Arad department. The data of the study area is first collected and pre-processed in ArcGIS. It consists of land use data, soil data, the DEM, stream gauges' and meteorological stations' locations, on the basis of which the watersheds' hydrologic parameters' are computed using the Geospatial Hydrologic Modelling Extension (HEC Geo-HMS). HEC Geo-HMS functions as an interface between ArcGIS and HEC-HMS (Hydrologic Engineering Centre- Hydrologic Modelling System) and converts the data collected and generated in ArcGIS to data useable by HEC-HMS. The basin model component in HEC-HMS represents the physical watershed. It facilitates the effective rainfall computation on the basis of the input hyetograph, passing the results to a transform function that converts the excess precipitation into runoff at the subwatersheds' outlet. This enables the estimation and creation of hydrographs for the ungauged watersheds. In the present study, the results are achieved through the SCS CN loss method and the SCS Unit hydrograph transform method. The simulations use rainfall data that is registered at the stations situated in the catchments' vicinity, data that spans over two decades (1989-2009) and which allows the rainfall hyetographs to be determined for the above mentioned return periods. The model will be calibrated against measured streamflow data from the gauging stations on the main rivers, leading to the adjustment of watershed parameters, such as the CN parameter. As the flood discharges for 10, 50 and 100 year return periods have been determined, the profile of the water surface elevation along the channel will be computed through a steady flow analysis, with HEC-RAS (Hydrologic Engineering Centre- River Analysis System). For each of the flood frequencies, a

    2015-04-01

    Over time, Dobrogea territory has faced with fluctuations more or less severe in terms of basic parameters such as temperature, precipitations and annual discharges of rivers. It is highlighted the trend of aridity in the area, because of the fact that Dobrogea receives small amounts of water, ranging between 200-450 mm/year, with annual average temperatures lying around and above the average of 11°C. This fact is also proceeding from the many studies realized by other researchers. For this area there are also characteristic torrents (form of rainfall during the summer), the storms and floods accompanying these torrents of water on the narrow valleys, often intermittent, sometimes causing significant damage and even fatalities. Torrential rainfalls and flash floods are sometimes very strong and produce catastrophic damages, as happened at Constanta (in 2001), at Tulcea (in 13.07.2004 and in 29.08.2004), at Tuzla, Pantelimon, Agigea and others. At the opposite pole of the sporadic excess rainfall is drought, which is the largest meteorological phenomenon (both in time and in space) and the most obvious in Dobrogea climate. Drought represents the main argument of semi aridity of this region and the most visible image component which is observed by the inhabitants of this environment. Correlation and study of hydro-meteorological extremes is performed using indices that take into account meteorological and hydrological parameters such as precipitations, temperature, discharges of rivers etc. Hydro-meteorological indices used for this study are: Angot rainfall index; Peguy Climograms; de Martonne drought index; Thornthwaite index Moduli coefficients and Deciles. According to the studied indices, for the accomplishment of this present paper, we can say that Dobrogea is among the driest regions in the country. History of drought in Romania includes many dry years, of which are mentioned: 1894, 1888, 1904, 1918, 1934, 1945, but the droughts years with greater durations

This chapter reviews, from the astronomical point of view, two of the monuments located on its Sacred Terrace - the altar known as the "Andesite Sun" and the Central Apse of the Great Round Sanctuary - as well as sanctuaries at the nearby site of Costeşti. Astronomical analyses taking into consideration (a) the astronomical-geometrical methods of the time (the analemma of a sundial after Vitruvius and the stereographical projection in the sense of Hipparchus), (b) astronomical instruments of the time (the gnomon, the sundial and the astrolabe), and (c) other instruments known to the Dacians (the compass), have concluded that these monuments may have enabled the Dacians to carry out a number of astronomical observations. This would confirm several reports by contemporary historians regarding the Dacians' knowledge of astronomy.

    Recent studies in radioactive waste management in Romania have focussed mainly on the disposal of low and intermediate level waste from the operation of the new nuclear power plant at Cernavoda. Following extensive geological, hydrological, seismological, physical and chemical investigations, a disposal site at Saligny has been selected. This paper presents description of the site at Saligny as well as the most important results of the site characterisation. These are reflected in the three-dimensional, stratigraphical representation of the loess and clay layers and in representative parameter values for the main layers. Based on these data, the simulation of the background, unsaturated-zone water flow at the Saligny site, calculated by the FEHM code, is in a good agreement with the measured moisture profile.

    The seismological database of the western part of Romania increased significantly during the last years, when 33 broadband seismic stations provided by SEIS-UK (10 CMG 40 T's - 30 s, 9 CMG 3T's - 120 s, 14 CMG 6T's - 30 s) were deployed in the western part of the country in July 2009 to operate autonomously for two years. These stations were installed within a joint project (South Carpathian Project - SCP) between University of Leeds, UK and National Institute for Earth Physics (NIEP), Romania that aimed at determining the lithospheric structure and geodynamical evolution of the South Carpathian Orogen. The characteristics of the background seismic noise recorded at the SCP broadband seismic network have been studied in order to identify the variations in background seismic noise as a function of time of day, season, and particular conditions at the stations. Power spectral densities (PSDs) and their corresponding probability density functions (PDFs) are used to characterize the background seismic noise. At high frequencies (> 1 Hz), seismic noise seems to have cultural origin, since notable variations between daytime and nighttime noise levels are observed at most of the stations. The seasonal variations are seen in the microseisms band. The noise levels increase during the winter and autumn months and decrease in summer and spring seasons, while the double-frequency peak shifts from lower periods in summer to longer periods in winter. The analysis of the probability density functions for stations located in different geologic conditions points out that the noise level is higher for stations sited on softer formations than those sited on hard rocks. Finally, the polarization analysis indicates that the main sources of secondary microseisms are found in the Mediterranean Sea and Atlantic Ocean.

  10. Vermiculation patterns in Coiba Mare cave, Bihor Mountains, Romania

    Vermiculation patterns developing on cave surfaces are certainly a spectacular feature. Sometimes vermiculation cover hundreds of square meters, like for example in Coiba Mare cave, which is situated in the Bihor Mountains, Romania. The Coiba Mare Cave is located at 1020 m altitude, on the Gardisoara Valley, not far from the Casa de Piatra Hamlet, in the Apuseni Natural Park (Bihor Mountains) situated in the western part of Romania. The first written document concerning the cave dates back to 1929, when R. Jeannel and E. Racovitza presented a brief description. Speleological investigations, which were started by I. Viehmann, D. Coman and M. Bleahu in 1953, were continued by several speleological clubs during 1975-1976. In this study, we are investigating the mineralogy, stable isotope distribution and patterns of vermiculations in the Coiba Mare cave. Material from the vermiculations developed on cave wall was analysed using Powder X-ray diffraction (PXRD), Fourier transformed infrared (FTIR) and energy dispersive analyses (EDS). The material consists mainly of calcite with traces of quartz, muscovite, chlinochlore, kaolinite, potassium feldspar and organic material. In Coiba Mare, the general look of the vermiculation pattern is that of a "pelli de leopardo" (Leopard's spots), a term used by Bini et al. (1978) for large vermiculations composed of clay. In the light of previous literature and according, to the own field and laboratory data a mechanism responsible for the formation of vermiculations is proposed. Evaporation and water film rupture cause the concentration of the loose particles. Evaporation is also associated with the formation of calcite microcrystals at the water-air interface. Concentration of the particle in vermiculations patterns and crystallisation is the result of evaporation and shrinking water spots.

    Romania successfully completed the world’s first air shipment of spent nuclear fuel transported in Type B(U) casks under existing international laws and without shipment license special exceptions when the last Romanian highly enriched uranium (HEU) spent nuclear fuel was transported to the Russian Federation in June 2009. This air shipment required the design, fabrication, and licensing of special 20 foot freight containers and cask tiedown supports to transport the eighteen TUK 19 shipping casks on a Russian commercial cargo aircraft. The new equipment was certified for transport by road, rail, water, and air to provide multi modal transport capabilities for shipping research reactor spent fuel. The equipment design, safety analyses, and fabrication were performed in the Russian Federation and transport licenses were issued by both the Russian and Romanian regulatory authorities. The spent fuel was transported by truck from the VVR S research reactor to the Bucharest airport, flown by commercial cargo aircraft to the airport at Yekaterinburg, Russia, and then transported by truck to the final destination in a secure nuclear facility at Chelyabinsk, Russia. This shipment of 23.7 kg of HEU was coordinated by the Russian Research Reactor Fuel Return Program (RRRFR), as part of the U.S. Department of Energy Global Threat Reduction Initiative (GTRI), in close cooperation with the Rosatom State Atomic Energy Corporation and the International Atomic Energy Agency, and was managed in Romania by the National Commission for Nuclear Activities Control (CNCAN). This paper describes the planning, shipment preparations, equipment design, and license approvals that resulted in the safe and secure air shipment of this spent nuclear fuel.

    Stable isotope ratios of meteoric water have an important role in climatic, paleoclimatic, hydrological and meteorological studies. While such data are available from most of Europe, so far, in Romania (East Central Europe), no systematic study of the stable isotopic composition of precipitation exists. In this context, the aim of this study is to analyze the isotopic composition of rainwater, its temporal and spatial distribution, the identification of the main factors influencing these variations and the creation of the first map of spatial distribution of stable isotopes in precipitation in Romania. Between March 2012 and March 2014 we have collected monthly samples from 22 stations in Romania, which were subsequently analyzed for their δ18O and δ2H at the Stable Isotopes Laboratory, Stefan cel Mare University, Suceava, Romania. Precipitation in W and NW Romania plot along the GMWL, while those in the East are slightly below it, on an evaporative trend. The LMWL for Romania is defined as δ2H=7,27*δ18O + 6,92. The W-E gradient in the distribution of δ18O and δ2H are less marked than the N-S ones, with local influences dominating in areas of strong evaporation (intramountain basins, rain-shadow areas etc). In SW, and especially in autumn and winter, Meditteranean cyclones carry moisture from the Eastern Mediterranean, the δ18O and δ2H values in precipitation in the area plotting between the GMWL and the Eastern Mediterranean Meteoric Water Line. The isotopic composition of rainwater in Romania correlates well with air temperature, and is influenced to a lesser extent by other factors such as the amount of precipitation, topography configuration, the effect of continentalism and season of the year.

    Problems in the post-mining regions of Eastern Europe range from degraded land and landscapes, huge insecure dumps, surface cracks, soil pollution, lowering groundwater table, deforestation, and damaged cultural potentials to socio economic problems like unemployment or population decline. There is no common prescription for tackling the development of post-mining regions after mine closure nor is there a common definition of good practices or policy in this field. Key words : waste management, legislation, EU Directive, post mining Rosia Montana is a common oh 16 villages; one of them is also called Rosia Montana, a traditional mining Community, located in the Apuseni Mountains in the North-Western Romania. Beneath part of the village area lays one of the largest gold and silver deposits in Europe. In the Rosia Montana area mining had begun ever since the height of the Roman Empire. While the modern approach to mining demands careful remediation of environmental impacts, historically disused mines in this region have been abandoned, leaving widespread environmental damage. General legislative framework Strict regulations and procedures govern modern mining activity, including mitigation of all environmental impacts. Precious metals exploitation is put under GO no. 190/2000 re-published in 2004. The institutional framework was established and organized based on specific regulations, being represented by the following bodies: • The Ministry of Economy and Commerce (MEC), a public institution which develops the Government policy in the mining area, also provides the management of the public property in the mineral resources area; • The National Agency for the development and implementation of the mining Regions Reconstruction Programs (NAD), responsible with promotion of social mitigation measures and actions; • The Office for Industry Privatization, within the Education Ministry, responsible with privatization of companies under the CEM; • The National

    The National Institute for Earth Physics (Romania) operates one of the largest seismic networks in the Eastern Europe. The network includes 97 stations with velocity sensors of which 52 are broadband and 45 are short period, 102 strong motion stations and 8 seismic observatories. Located in the most active seismic region of Romania, i.e. Vrancea area, the Plostina Observatory included initially two seismic stations, one at surface with both broadband and accelerometer sensors and one at 30 m depth with only short period velocity sensor. Starting with 2007, the facilities at Plostina have been upgraded so that at present, the observatory also includes one seismic array (PLOR) of seven elements (PLOR1, PLOR2, PLOR3, PLOR4, PLOR5, PLOR6, PLOR7) with an aperture of 2.5 km, seven infrasound elements (IPL2, IPL3, IPL4, IPH4, IPH5, IPH6, IPH7), two three-component fluxgate sensors, one Boltek EFM-100 electrometer and one La Crosse weather station. The element PLOR4 is co-located with the accelerometer and borehole sensor, two infrasonic elements (IPL4 and IPH4), one fluxgate sensor, the Boltek electrometer and the weather station. All the date are continuously recorded and real-time transmitted to the Romanian National Data Centre (RONDC) in Magurele. The recent developments at Plostina site made possible the improvement of the local miscroseismic activity monitoring as well as conducting of other geophysical studies such as acoustic measurements, observations of the variation of the magnetic field in correlation with solar activity, observations of the variation of radioactive alpha gases concentration, observations of the telluric currents. In this work, we investigate the signals emitted due to the process of lightning and thunder during thunderstorms activity at Plostina site. These signals are well recorded by both seismic and infrasound networks and they are used to perform spectral and specific array analyses. We also perform multiple correlations between the

    The impact of climate changes varies considerably in Europe, with different degrees of vulnerability. Romania is situated in an area with the lowest capacity to adapt to existing climate change and those that will occur, and the Transylvanian Plain (TP) is one of the most affected areas. In these conditions, the climate monitoring and implementation of measures to adapt to these changes are essential for sustainable development of agricultural technologies. The TP name comes from the Latin "silva" which means forest, namely an area covered with forests approximately 55-60% in the early nineteenth century, but today reached an average of 6.8% in the TP area. In time, the rugged terrain, deforestation, erosive slopes, and irrational agro technical practices for crop production altogether brought about the degradation of large areas of agricultural land, reducing its productivity. The degree of soil degradation in TP and climate change in recent years, have radically modified climatic conditions for cultural crops. Monitoring of temperature and water supply in TP aims to evaluate these two resources for agricultural production. The TP is a geographical region located in north-central Romania and it is bordered by large rivers to the north and south: the Somes and the Mures rivers. The altitude of the TP ranges from 231 to 662 m. TP, with an area of approx. 395,616 ha, includes areas of three counties (Cluj - CJ, Mures -MS, Bistrita-Nasaud - BN), has a predominantly agricultural character, and is characterized by hilly climate with oceanic influences, 9-100C average annual temperatures and 500-700 mm/year average annual precipitations. Monitoring the thermal and water supplies from TP was performed with twenty HOBO micro stations which determine the temperature (to a height of 1 m) and rainfalls same as temperature (at 10, 30, 50 cm depth in soil) and soil moisture (at 10 cm depth).

    River restoration is at the forefront of applied hydrologic science. However, many river restoration projects are conducted with minimal scientific context. We propose two themes around which a research agenda to advance the scientific basis for river restoration can be built. First, because natural variability is an inherent feature of all river systems, we hypothesize that restoration of process is more likely to succeed than restoration aimed at a fixed end point. Second, because physical, chemical, and biological processes are interconnected in complex ways across watersheds and across timescales, we hypothesize that restoration projects are more likely to be successful in achieving goals if undertaken in the context of entire watersheds. To achieve restoration objectives, the science of river restoration must include (1) an explicit recognition of the known complexities and uncertainties, (2) continued development of a theoretical framework that enables us to identify generalities among river systems and to ask relevant questions, (3) enhancing the science and use of restoration monitoring by measuring the most effective set of variables at the correct scales of measurement, (4) linking science and implementation, and (5) developing methods of restoration that are effective within existing constraints. Key limitations to river restoration include a lack of scientific knowledge of watershed-scale process dynamics, institutional structures that are poorly suited to large-scale adaptive management, and a lack of political support to reestablish delivery of the ecosystem amenities lost through river degradation. This paper outlines an approach for addressing these shortcomings.

    In June 2009 two air shipments transported both unirradiated (fresh) and irradiated (spent) Russian-origin highly enriched uranium (HEU) nuclear fuel from two research reactors in Romania to the Russian Federation for conversion to low enriched uranium. The Institute for Nuclear Research at Pitesti (SCN Pitesti) shipped 30.1 kg of HEU fresh fuel pellets to Dimitrovgrad, Russia and the Horia Hulubei National Institute of Physics and Nuclear Engineering (IFIN-HH) shipped 23.7 kilograms of HEU spent fuel assemblies from the VVR S research reactor at Magurele, Romania, to Chelyabinsk, Russia. Both HEU shipments were coordinated by the Russian Research Reactor Fuel Return Program (RRRFR) as part of the U.S. Department of Energy Global Threat Reduction Initiative (GTRI), were managed in Romania by the National Commission for Nuclear Activities Control (CNCAN), and were conducted in cooperation with the Russian Federation State Corporation Rosatom and the International Atomic Energy Agency. Both shipments were transported by truck to and from respective commercial airports in Romania and the Russian Federation and stored at secure nuclear facilities in Russia until the material is converted into low enriched uranium. These shipments resulted in Romania becoming the 3rd country under the RRRFR program and the 14th country under the GTRI program to remove all HEU. This paper describes the research reactor preparations and license approvals that were necessary to safely and securely complete these air shipments of nuclear fuel.

    The occurrence and importance of photoautotrophic picoplankton (PPP, cells with a diameter <2 μm) was studied along a trophic and salinity gradient in hypersaline lakes of the Transylvanian Basin (Romania). The studied lakes were found to be rich in PPP, with abundances (maximum 7.6 × 10(6) cells mL(-1)) higher than in freshwater and marine environments of similar trophic conditions. The contribution of PPP to the total phytoplankton biovolume did not decrease with increasing trophic state as it was generally found in other aquatic environments. Regardless of the trophic conditions, the contribution of PPP could reach 90-100 % in these hypersaline lakes. We hypothesized that the PPP predominance might be the result of the low grazing pressure, since heterotrophic nanoflagellates (the main grazers of PPP) were absent in the studied samples. There were significant differences in community composition among the lakes along the salinity gradient. CyPPP predominated in less saline waters (mainly below 5 %), while EuPPP were present along the entire salinity range (up to 18.7 %), dominating the phytoplankton between 3 and 13 % salinity. Above 13 % salinity, the phytoplankton was composed mainly of Dunaliella species.

    Prosthetics is a modern area of interest and a challenge in Orthopedics. Over time, there has been a transition from an artisanal method of prosthetics production to modern concepts and materials, including a re-education through virtual reality. The conditions for an efficient fitting of a prosthesis include the necessity that the prosthesis respects the form and function of the lost limb, both anatomically and biomechanically. Prosthetics are made individually, personalized according to sex, age, physiological characteristics, profession and preference. In our country, thoracic limb prosthetics has a relatively short-recorded history of approximately a century, the most preeminent centers being in Iasi, Cluj and Bucharest. Currently, thoracic limb prosthetics, and particularly hand prosthetics, are in a period of development. A technique for amputation and stump reamputation called “circumferential osteoneuromioplasty” (CONM) is currently being used in the Orthopedics and Trauma Clinic of the Central Military University Emergency Hospital in Bucharest. The method was created with the purpose of obtaining distinct myoelectric signals of better quality, following the contraction of each muscle. The CONM method can be used in conjuncture with both the new hand prostheses that are currently available in Romania, and with the model that is being developed by a mixed team from the Polytechnic University in Bucharest, in collaboration with the Central Military University Emergency Hospital in Bucharest.

    Animals from seven zoological gardens located in Romania, including 18 species of herbivores, 10 species of carnivores, and 13 species of omnivores, were screened for the presence of parasites. Overall, the prevalences of parasites identified in the sampled population were 54.2% (58/107) for herbivores, 54.5% (24/44) for carnivores, and 32.6% (17/52) for omnivores. In herbivores, Eimeria spp., Dicrocelium lanceolatum, and pulmonary and digestive strongyles were detected. In carnivores, the genera Eimeria and Cystoisospora and nematodes from Ancylostomatidae, Strongyloidae, Ascaridae, Capillariidae and Trichocephalidae were identified. Of 13 omnivore species included in the study, parasites from Eimeridae, Ascaridae, Strongyloidae, and Trichocephalidae were identified in seven species. Toxoplasma antibodies were identified using enzyme-linked immunosorbent assay in all definitive hosts (lions and wild cats) examined. In intermediate hosts (herbivores and omnivores), antibodies to Toxoplasma gondii had a prevalence of 58.8%, except in wild boars (Sus scrofa), in which the prevalence was 100%.

    The paper (communication) presents an overview of hydrologic field experiments at micro-scale in Romania. In order to experimentally investigate micro (plot)-scale hydrological impact of soil erosion, the National Institute of Hydrology and Water Management founded Voineşti Experimental Basin (VES) in 1964 and the Aldeni Experimental Basins (AEB) in 1984. AEB and VES are located in the Curvature Subcarpathians. Experimental plots are organized in a double systems and have an area of 80 m2 (runoff plots) at AEB and 300 m2 (water balance plots) at VES. Land use of plot: first plot "grass-land" is covered with perennial grass and second plot (control) consists in "bare soil". Over the latter one, the soil is hoeing, which results in a greater development of infiltration than in the first plot. Experimental investigations at micro-scale are aimed towards determining the parameters of the water balance equation, during natural and artificial rainfalls, researching of flows and soil erosion processes on experimental plots, extrapolating relations involving runoff coefficients from a small scale to medium scale. Nowadays, the latest evolutions in data acquisition and transmission equipment are represented by sensors (such as: sensors to determinate the soil moisture content). Exploitation and dissemination of hydrologic data is accomplished by research themes/projects, year-books of basic data and papers.

    2014-01-01

    In the summer of 2010, Romania undertook a process of hospital decentralisation as part of the reform in the healthcare sector. The national newsprint media covered the process thoroughly. This paper is a study of how key stakeholders' views, attitudes, beliefs and attitudes towards decentralisation are represented in print media. 106 articles, published between June and September 2010, retrieved from the online databases of six leading national dailies were analysed. A mixed methodology was used in the data analysis stage. The qualitative data exploration identified five voices belonging to stakeholders involved directly or indirectly in the process: the representatives of central government, the local authorities (district and local councils, municipal mayors), health professionals (managers and physicians in hospitals), the media (journalists, analysts) and finally voices from civil society, professional associations and advocacy groups. These were the main actors negotiating the subjective meanings of the decentralisation process. An imbalance between these key actors were observed in the frequency, content and tone of the messages delivered in media during the four months. Central government and the local authorities were the most active voices, but the respective discourses differed significantly.

    We present our efforts in establishing a Research Pole in Photonics in the future Arad-Timisoara metropolitan area projected to unite two major cities of Western Romania. Research objectives and related training activities of various institutions and groups that are involved are presented in their evolution during the last decade. The multi-disciplinary consortium consists principally of two universities, UAVA (Aurel Vlaicu University of Arad) and UMF (Victor Babes Medicine and Pharmacy University of Timisoara), but also of the Arad County Emergency University Hospital and several innovative SMEs, such as Bioclinica S.A. (the largest array of medical analysis labs in the region) and Inteliform S.R.L. (a competitive SME focused on mechatronics and mechanical engineering). A brief survey of the individual and joint projects of these institutions is presented, together with their teaching activities at graduate and undergraduate level. The research Pole collaborates in R&D, training and education in biomedical imaging with universities in USA and Europe. Collaborative activities, mainly on Optical Coherence Tomography (OCT) projects are presented in a multidisciplinary approach that includes optomechatronics, precision mechanics and optics, dentistry, medicine, and biology.

    As a result of the Fukushima nuclear release, (131)I was found in different environmental media (rainwater, sheep and cow milk, herbage, sheep meat and thyroid tissue) in north-west Romania. On April 4, 2011 a maximum value of 1.40 ± 0.21 Bq/L in (131)I activity was found in rainwater obtained from the Arad region. The obtained value corresponded with the maximum of (131)I concentration in air, as measured by Toma et al. (2011) for the Piteşti area. One day later, sheep milk from the Cluj area was found to contain a maximum activity of 9.22 ± 0.95 Bq/L. A value of 0.85 ± 0.07 μSv was calculated as the total monthly effective dose received by the population as a result of the ingestion of sheep milk and sheep meat contaminated with (131)I. Only rainwater samples contained (134)Cs and (137)Cs at levels close to minimum detectable activity. Since the determined values could be influenced by Chernobyl (137)Cs, the (137)Cs concentrations are subject to uncertainty. The radioiodine transfer coefficients (Fm) and the concentration ratio (CR) from herbage to sheep milk, as well as sheep meat, from the Cluj-Apahida area are also presented.

  11. Stratigraphic and structural distribution of reservoirs in Romania

    In Romania, there are reservoirs at different levels of the whole Cambrian-Pliocene interval, but only some of these levels have the favorable structural conditions to accumulate hydrocarbons in commercial quantities. These levels are the Devonian, Triassic, Middle Jurassic, Lower Cretaceous (locally including the uppermost Jurassic), Eocene, Oligocene-lower Miocene, middle and upper Miocene, and Pliocene. The productive reservoirs are represented either by carbonate rocks (in Devonian, Middle Triassic and uppermost Jurassic-Lower Cretaceous) or by detrital rocks (in Lower and Upper Triassic, Middle Jurassic, Eocene, Oligocene, Miocene, and Pliocene). From the structural point of view, the Romanian territory is characterized by the coexistence both of platforms (East European, Scythian, and Moesian platforms) and of the strongly tectonized orogenes (North Dobrogea and Carpathian orogenes). Each importance crust shortening was followed by the accumulation of post-tectonic covers, some of them being folded during subsequently tectonic movements. The youngest post-tectonic cover is common both for the platforms (foreland) and Carpathian orogene, representing the Carpathian foredeep. Producing reservoirs are present in the East European and Moesian platforms, in the outer Carpathian units (Tarcau and Marginal folds nappes) and in certain post-tectonic covers which fill the Carpathian foredeep and the Transylvanian and Pannonian basins. In the platforms, hydrocarbons accumulated both in calcareous and detrital reservoirs, whereas in the Carpathian units and in their reservoirs, whereas in the Carpathian units and in their post-tectonic covers, hydrocarbons accumulated only in detrital reservoirs.

    Honey is used in food industry and medicine due to its nutritive, therapeutic and dietetic qualities. The microbiological characteristics of 10 unpasteurized honey samples of known origin, collected from Transylvania beekeepers (Romania) were determined. The antibacterial activity of these types of honey against Escherichia coli, Staphylococcus aureus, Staphylococcus epidermidis, Salmonella enteritidis, Salmonella anatum, Salmonella choleraesuis, Bacillus cereus, Bacillus subtilis subsp. spizizenii and Listeria monocytogenes strains was studied. The most sensitive to the antibacterial activity were the two staphylococus strains (the largest diameter of inhibition zone was 18 mm) and B. subtilis strains (13.5 mm). The strains of B. cereus, E. coli, L. monocytogenes and Salmonella spp. were found to present resistance to some of the honey samples. Manna, sunflower and polyfloral honeys presented high antibacterial activity while acacia and linden honeys had a lower activity in terms of the number of sensible strains. Statistical analysis shows that the type of strains and the type of honey have influence on the diameter of inhibition. PMID:24380618

    According to European Directives, transposed in national legislation, the Member States should organize separate collection systems at least for paper, metal, plastic, and glass until 2015. In Romania, since 2011 only 12% of municipal collected waste was recovered, the rest being stored in landfills, although storage is considered the last option in the waste hierarchy. At the same time there was selectively collected only 4% of the municipal waste. Surveys have shown that the Romanian people do not have selective collection bins close to their residencies. The article aims to analyze the current situation in Romania in the field of waste collection and management and to make a proposal for selective collection containers layout, using geographic information systems tools, for a case study in Romania. Route optimization is used based on remote sensing technologies and network analyst protocols. Optimizing selective collection system the greenhouse gases, particles and dust emissions can be reduced.

    The evolution of energy sector worldwide triggered intense preoccupation on both finding alternative renewable energy sources and environmental issues. Romania is considered to have technological potential and geographical location suitable to renewable energy usage for electricity generation. But this high potential is not fully exploited in the context of policies and regulations adopted globally, and more specific, European Union (EU) environmental and energy strategies and legislation related to renewable energy sources. This SWOT analysis of solar energy source presents the state of the art, potential and future prospects for development of renewable energy in Romania. The analysis concluded that the development of solar energy sector in Romania depends largely on: viability of legislative framework on renewable energy sources, increased subsidies for solar R&D, simplified methodology of green certificates, and educating the public, investors, developers and decision-makers.

    When speaking about Professor Gheorghe Bilaşcu (1863-1926) and his major contribution to the establishment of Romanian medical education in Cluj, he should be considered not only in terms of scientist and creator of the Dental School, but also through his commitment to the development of science and culture in Romania. A wealthy dentist in Budapest where he graduated from the Dental School, he supported a lot of Romanian students to attend schools and universities in the Budapest, thus contributing to the development of culture in his own country. Finally, he left his private practice in the Capital of Hungary to come to Cluj to support the efforts of building the Dental School and profession in Romania. This paper illustrates the contribution that Professor Gheorghe Bilaşcu made to the development of higher education in Romania, as well as his support of the local culture. PMID:27547068

    The present study aims at investigating the concentrations and distribution levels of a series of trace elements in water and sediment samples collected from six storage lakes located in the Jijia catchment - NE of Romania. The lakes are multi-purpose water reservoirs, three of them being mainly used as a source of municipal drinking water, or for fishing, irrigation for the farms in the area, protection against floods and the regulation of river flows. By contrast, agricultural wastes, fertilizers, raw sewage effluents and road runoff constitute the predominant anthropogenic sources, which supply the lakes in question with Cd, Cu, Pb and Zn. The present study was conducted on a series of 63 sediment samples and 18 water samples, collected from the same locations, in order to establish the distribution levels of certain trace elements from the water through sediments. Sediment cores were collected from two sections across each lake by means of a motor boat, using a system that consists of a graduated sampling tube (0.9 m in length and 72.5 mm in diameter) made of Plexiglas (Eijkelkamp sample tube guide). Prior to the analyses, the samples were air-dried, ground and homogenized using an agate mortar, oven-dried at 50 °C for 6 days and then sieved through 63 µm sieves. The sediment and water samples were subjected to a digestion technique with concentrated nitric acid using a microwave oven (Berghof type), and analyzed for the following elements: Pb, Zn, Cu, Cd, Cr and Ni. The total concentration of the elements was measured through atomic absorption spectrometry (AAS) with an RSD of < 10 % from solutions. The vertical distribution of most elements in the cores examined could be characterized as relatively uniform, with higher concentrations for those collected from the lakes which are more influenced by anthropogenic factors, compared to those situated in forested areas. The lake-water quality characteristics were below the recommended drinking water standards

The program consists of multiple components: a U.S.- based MA degree program for long-term trainees, Romania-based short courses, a U.S.-based opportunity for mid-and senior-level personnel to develop collaborative writing or research projects and present lectures, and a newsletter and various Internet-based activities. We evaluated the impact of the training program on bioethics in Romania through a survey of the training program's long-term trainees, a literature search for trainee publications, interviews with key informants, and identification of key events during the course of the program. Findings indicate that the program has had a considerable impact in the field of bioethics through trainee authorship of peer-reviewed publications, books, and chapters; trainee career trajectories that encompass activities related to research ethics; and the development of a Romania-based master's degree program in bioethics and a Center of Bioethics and Health Policy. We attribute these achievements to the establishment of strong relationships between CWRU in Cleveland and the University of Medicine and Pharmacy Gr. T.

    The Paratethys epicontinental sea has been an essential paleogeographic feature defining the Eurasian interior since Oligocene. By the end of the Miocene, ongoing tectonic activity in the region determined severe restrictions of the connection of the large former Paratethys sea resulting in the formation of several smaller subbasins: the Pannonian basin, the Dacian basin, the Black Sea and the Caspian Sea. In the western part of the Dacian Basin, the thick and continuous Mio-Pliocene sedimentary successions of the Getic Depression of Romania provide an exceptional opportunity to study the paleoecological changes in the Eastern Paratethys during the time when the Mediterranean and Black Sea experienced important sea level changes related to the Messinian Salinity Crisis. These sedimentary successions were the basis of high-resolution magnetobiostratigraphic studies that allow a detailed correlation to the Geological Time Scale. Here, we present the main characteristics of the ostracod assemblages of the Late Miocene/Pliocene sedimentary succession from Badislava-Topolog section covering the Eastern Paratethys regional Maeotian and Pontian, stages that are, at moment, under ongoing formal stratigraphic definition process. The Mio-Pliocene is exposed in the central part of the Getic Depression, especially Topolog-Arges area, where it riches up to 500 m in thickness being incorporated into a large monocline structure with 15o-20o plungeto the south. The Upper Maeotian deposits from the area have developed mainly in fluviatile-deltaic facies with frequent continental intercalations. The ostracod assemblage is represented by rare fresh water ostracods of Candona, Pseudocandona and Ilyocypris genera, capable to populate unstable environments like flood-plains, lakes and rivers with temporary existence. The scarce Maeotian ostracod fauna from this marginal section differs essentially from the more diversified one of the same age recorded in areas that evolved in basinal

    Keywords: mining, AMD mitigation, isotopic analyses, Romania Rosia Montana is one of the most important European gold fields, with a long history of mining. The extraction of gold started on site during the Roman age, and the mining operations that spanned over almost two millennia have produced a visible environmental footprint. More than 140 km of mining galleries are documented by historical sources and recent surveys. Water streams are the main vectors spreading the pollution outside the mining area. The main streams, Rosia, Corna, and Saliste, tributaries of Abruzel River are significantly impacted by the acid waters issued by adits, exposed rock surfaces, or rock waste heaps, and tailings depots. Low contamination has been observed in the streams outside the mining area, artificial ponds, and shallow groundwater. Excepting the shallow groundwater system that can be sampled in domestic wells and some springs, the circulation of groundwater is largely unknown. An important amount of the infiltration water is channelled through galleries. The waters sampled at the galleries outlets have low pH, generally between 2 and 3, and very high content of heavy metals. A systematic approach based on monthly sampling and chemical analyses, and isotopic measurements, has been initiated, in order to better understand the underground itinerary of water and the chemical transformations that occur. A sampling network of 28 water points, including streams, ponds, dug wells, springs, and gallery outlets has been setup. Beyond producing a water circulation model in the mining area, the main purpose of the research is to identify ways of decreasing the acid water production and to design low cost techniques for the AMD mitigation. The deposit still hosts about 300 tonnes of gold, and 1600 tonnes of silver. A new large scale mining project is currently under permitting. Cost-effective solutions for the water treatment would be beneficial, especially for the post-mining stage of any

    Ocular thelaziosis by Thelazia callipaeda is a vector-borne disease that infects domestic and wild carnivores as well as humans. In this paper, we present two cases of ocular thelaziosis in dogs that had never traveled outside Romania. Both presented with moderate conjunctivitis and ocular discharge. In total, 41 adult nematodes were removed from the conjunctival sacs of both dogs; these were identified via morphology as T. callipaeda. To the best of our knowledge, this is the first report of canine ocular thelaziosis caused by T. callipaeda from the Muntenia Region of Romania. PMID:26898833

    This study sets out to investigate the changes in the perception of women in leading positions in communist and postcommunist Romania. The study uses a noninvasive paradigm of analyzing the content of obituaries for women and men in leading positions published in a national journal, and shows that the gender gap in management widened during the postcommunist period. In postcommunist Romania, women are perceived as being less able to lead/manage and more relational in their leadership style as compared to men, while in the communist period the gender differences were not significant.

    The western part of Romania was poorly investigated until now in terms of crust and lithosphere structure. The South Carpathian Project (SCP) is a joint project in Romania aimed at determining the lithospheric structure and geodynamical evolution of the South Carpathian Orogen using a dense, temporary network of broad-band seismographs. Alongside existing permanent broad band stations in the study region (12), 33 broadband seismic stations were installed in September 2009 to operate autonomously for two years. We analyze teleseismic P-to-S receiver functions to image crustal structure and uppermost lithosphere. The receiver functions (RF) are calculated in time domain by iterative deconvolution. The further data processing and analysis was performed using FuncLab, a GUI-based MATLAB receiver function processing toolkit (Eagar and Fouch, submitted 2011). We apply a common conversion point (CCP) stacking of receiver functions - a method used to image smooth regional topography on subhorizontal interfaces (Eagar et al. 2010). It is a back-projection method in which the receiver function amplitudes are placed in the appropriate position along the raypath based on a time-to-depth conversion. These amplitudes are then binned at each depth based on the position of the ray piercing point and then stacked to enhance the signal originating from that approximate position. We first perform 1-D ray tracing, then accommodate for large lateral variations in seismic velocities across the region by applying linear timing corrections based on a high resolution regional S wave tomography model (Young et al., in preparation) and then compute the time-to-depth conversion of the receiver functions. The final step in the workflow is CCP stacking. We also apply a Gaussian-weighted common conversion point stacking (GCCP) by weighting the receiver functions within the stacks by the distance of the piercing point from the image point, which is the same as the center point of the CCP bin.

    Diana Cave is located within the town limits of Baile Herculane (SW Romania) and develops as a 14 m long, westward oriented, unique passage guided by the Diana fault [1]. At the far end of the cave, the thermo-mineral Diana Spring wells forth. In the early 1970s a mine gallery that intersected the cave was created to drain the water into a pumping station and the original cave passage was somewhat altered and reinforced with concrete. Today the concrete and the silty limestone cave walls are heavily corroded by H2SO4 outgassing from the hot water (ca. 50°C) and display abundant gypsum crusts, soggy aggregates of native S, and a variety of more exotic sulfates. Among them, a mineral that has been previously identified in caves only in connection to volcanic activity, either as thermal springs or fumaroles [2]: tamarugite [NaAl(SO4)26H2O]. It was [3] that first mentioned the occurrence of this Na and Al sulfate in Diana Cave, our research aiming to give a detailed description of this mineral, its paragenesis, and mechanisms of precipitation. Recently, tamarugite has also been identified in a sulfuric acid cave from Greece [4]. Along with powder X-ray diffractions coupled with Rietveld refinement, scanning electron microscope, and electron probe micro-analysis, δ18O and δ34S compositions of the sulfate mineral as well as precipitates from the water were analyzed to identify and better constrain the genesis of this rare sulfate. Regrettably, the crystal size of our specimens is inappropriate for identification by means of single crystal X-ray diffraction. Physical and chemical parameters of Diana Spring were as well measured on several occasions. Geochemical analysis suggests that the minute, white tamarugite flakes precipitated in Diana Cave as a result of the interactions between the thermo-mineral water or water vapor and the original limestone bedrock and concrete that blankets the mine gallery.

    Sustainable mining practices and consistent implementation of the mining for the closure planning approach, within an improved legislative framework, create conditions for the development of creative, profitable, environmentally-sound and socially-responsible management and reuse of mine lands. According to the World Commission on Environment and Development definition, sustainable development is the type of development that meets the needs of the present without compromising the ability of future generations to meet their own needs. Romania has the largest gold reserves in Europe (760 million tons of gold-silver ores, of which 40 million tons in 68 gold deposits in the Apuseni Mountains. New mining projects draw particular attention regarding the environmental risks they cause. Rehabilitation is an ongoing consideration throughout the mine's lifecycle, both from a technical and a financial standpoint. The costs of land rehabilitation are classified as the mine's operating costs. According to Directive 2004/35/EC on environmental liability, the prevention and remedying of environmental damage should be implemented by applying the "polluter pays" principle, in line with the principle of sustainable development. Directive on the management of waste from extractive industries and amending Directive obliges operators to provide (and periodically adjust in size) a financial guarantee for waste facility maintenance and post-closure site restoration, including land rehabilitation. According to the Romanian Mining Law, the license holder has the following obligations related to land use and protection: to provide environmental agreements as one of the prerequisites for a building permit; to regularly update the mine closure plan; to set up and maintain the financial guarantee for environmental rehabilitation; and to execute and finalize the environmental rehabilitation of affected land in the mining site, according to the mine closure plan, including the post

    The report released by the Intergovernmental Committee for Climate Change indicates that Romania ranks among the top seven countries in Europe that would be strongly impacted by aridity in the next few years, with climate changes consisting in a rise of average annual temperatures by as much as 5°C. The research work was conducted in the South of the Oltenia South-Western Development Region, where more than 700,000 hectares of farmland is impacted by aridification, more than 100,000 hectares among them impacted by aridity. Research methodology encompassed the analysis of average annual temperatures over the time span data was available for, at three weather stations, an analysis of average annual precipitations, an analysis of the piezometric data, the evolution of land use as a result of the expansion of the aridity process. The assessment of the aridity process also involved taking into consideration the state of the vegetation by means of the normalized difference vegetation index (NDVI), used to assess the quality of the vegetal stratum, an important element in the complex analysis of the territory. The aridity process is an effect of global warming, and, based on the results of this study, the post-1990 escalation of its effects was brought about by socio-economic factors. The destruction of the irrigation systems and protective forest belts because of the uncertain situation of land ownership are the main factors that contributed to amplification of the effects of aridity on the efficiency of agricultural systems that nowadays are exposed to very high risks.

    The Barlad Plateau, extending about 8,230 square kilometers is considered as the most typical unit of the Moldavian Plateau of the Eastern Romania. The Miocene-Pliocene clay-sandy layers are inter-bedded with shallow sandstone and limestone seams. These sedimentary layers that have outcropped as a result of erosion are gently dipping toward S-SE in the form of a monocline. Landslides have been recognized as an important environmental threat in the major subunits of the Barlad Plateau, namely: Central Moldavian Plateau, Falciu Hills and Tutova Rolling Hills. Four main areas of monitoring landslides were explored such as successive aerial photographs of the 1960, 1970, 2005 and 2009 flights, repeated field surveys for a thorough reconnaissance of the study area, classical levelling work and GIS software applications as TNT Mips and Arc GIS. Also, the Caesium-137 technique has been used to get information on documenting sedimentation rates in some small catchments. Results have indicated that the landslide development is strongly controlled by the northern and western looking steep faces of cuestas, by changes of rock composition and by human impact. Also, it showed great pulses in conjunction with the rainfall distribution. For example, half of the Upper Barlad catchment that drains an area of 22,560 ha is covered by landslides. Furthermore, the active landslides amounted 11% of the total (2,317 ha) after the rainy 1968-1973 period and since 1982 under drier conditions they gradually limited to 444.0 ha (2% of the total).

    On 7 May 2005, a squall line with an embedded bow echo formed over Southern Romania causing severe wind damage. The length of the wind damage was around 150 km. Three tornadoes have been reported, two of them being recorded by video camera. One of the tornadoes occurred in Buftea (near Bucharest), the second in Ciobanu village (near Medgidia radar site) and the third in Movilita village, 40 km to the northeast of Bucharest. The site surveys confirmed wind damage associated with these tornadoes. Based on damage, the Movilita village tornado was classified as an F1 type on the Fujita scale, and the Buftea and Ciobanu village tornadoes were classified as F0. Large scale forcing was provided by a vigorous upper level trough. The squall line developed in the warm sector of a low, ahead of the cold front. The Bucharest EEC-DWSR-2500C Doppler velocity depicted cyclonically rotational structures associated with the left end of the bow echo. In two hours this squall line traversed the southern part of the country. The northern end of the line preserved the bowed structures and high reflectivity gradient in front of them. The dry air associated with the descending rear inflow jet was evident as rear inflow notches in the reflectivity field of the Bucharest C-band radar and the Medgidia S-band WSR-98 D radar. The synoptic and mesoscale environment associated with 7 May 2005 bow echo had many similarities to the "dynamic" pattern described by John and Hirt (1987). Herein are analyzed the combined effects of synoptic and mesoscale circulations, together with the data provided by C-band EEC-DWSR-2500C and S-band WSR-98D radars, and the ECMWF and ALADIN model output data. Some operational aspects of the warning process are also discussed.

  12. Relationship between gullying and landslides within the Barlad Plateau, Romania

    Located in the eastern Romania and extending on 8200 km2 the Barlad Plateau is considered the most typical subunit of the Moldavian Plateau. The sedimentary Miocene-Pliocene clay-sandy layers, inter-bedded with shallow sandstone and limestone are gently dipping toward S-SE as homoclinal structure. Land degradation through soil erosion, gullying and landslides represent the most important environmental threat in the region. By using both the classical research methods such as repeated field surveys and mapping, mathematical-statistical processing as well as the present-day methods based on the GIS software it was possible to precisely measure and evaluate the gully erosion rates and triggered landslides during the last two centuries, especially with a very high accuracy since 1960. Results have indicated that the landslide development is strongly controlled by gullying. Generally, by combining the areal growth of both gullying and new landslides within the selected study catchments, it is noticeable that 62 % of the total recent land degradation occurred during the last 55 years, with the remainder pre-1960. In addition, half of the gully areal growth occurred since 1961 but the new triggered landslides amount over three-quarters of the total area under landslides. This asymmetrical distribution reveals that usually a preparing time lag of tens of years is required for triggering landslides by gullying and this pattern depicts the common mechanism for landslide development.

    Problems in the post-mining regions of Eastern Europe range from degraded land and landscapes, huge insecure dumps, surface cracks, soil pollution, lowering groundwater table, deforestation, and damaged cultural potentials to socio economic problems like unemployment or population decline. There is no common prescription for tackling the development of post-mining regions after mine closure nor is there a common definition of good practices or policy in this field. Key words : waste management, legislation, EU Directive, post mining Rosia Montana is a common oh 16 villages; one of them is also called Rosia Montana, a traditional mining Community, located in the Apuseni Mountains in the North-Western Romania. Beneath part of the village area lays one of the largest gold and silver deposits in Europe. In the Rosia Montana area mining had begun ever since the height of the Roman Empire. While the modern approach to mining demands careful remediation of environmental impacts, historically disused mines in this region have been abandoned, leaving widespread environmental damage. General legislative framework Strict regulations and procedures govern modern mining activity, including mitigation of all environmental impacts. Precious metals exploitation is put under GO no. 190/2000 re-published in 2004. The institutional framework was established and organized based on specific regulations, being represented by the following bodies: • The Ministry of Economy and Commerce (MEC), a public institution which develops the Government policy in the mining area, also provides the management of the public property in the mineral resources area; • The National Agency for the development and implementation of the mining Regions Reconstruction Programs (NAD), responsible with promotion of social mitigation measures and actions; • The Office for Industry Privatization, within the Education Ministry, responsible with privatization of companies under the CEM; • The National

  1. Foster care and adoption policy in Romania: suggestions for international intervention.

    PubMed

    Johnson, A K; Edwards, R L; Puwak, H

    1993-01-01

    Building an effective child welfare system is a monumental task facing postrevolution Romania. Following revelations on American and Western European television about the large number of "orphans" in Romania, many couples flocked to that country to adopt children. A significant number of adopted Romanian children were brought to the United States. Some of these children are now evidencing problems that are bringing them to the attention of health and social service agencies. This article examines the macroeconomic policies that led to the institutionalization of a large number of children in Romania. Although institutional care is the current norm, a legal basis exists for building family foster care as an alternative. Romania's new adoption law replaces private adoptions with agency-based work. International adoption agencies are involved in developing community-based foster care and permanency planning as part of their work. This article challenges international adoption agencies to use clinical assessments of developmental delays and more rigorous health examinations for children released for adoption.

  13. Preliminary results regarding the first map of residential radon in some regions in Romania.

    2013-07-01

    Radon represents the most important contribution of population exposure to natural ionising radiation. This article presents the first indoor radon map in some regions of Romania based on 883 surveyed buildings in the Ştei-BăiŢa radon-prone region and 864 in other regions of Romania. Indoor radon measurements were performed in the last 10 y by using CR-39 nuclear track detectors exposed for 3-12 months on ground floor levels of dwellings. Excluding the Ştei-BăiŢa radon-prone region, an average indoor radon concentration of 126 Bq m(-3) was calculated for Romanian houses. In the Ştei-BăiŢa radon-prone area, the average indoor concentration was 292 Bq m(-3). About 21 % of the investigated dwellings in the Ştei-BăiŢa radon-prone region exceed the threshold of 400 Bq m(-3), while 5 % of the dwellings in other areas of Romania exceed the same threshold. As expected, indoor radon concentration is not uniformly distributed throughout Romania. The map shows a high variability among surveyed regions, mainly due to the differences in geology. The radon emanation rate is substantially influenced by the soil characteristics, such as the soil permeability and soil gas radon concentration. Since higher permeability enables the increased migration of soil gas and radon from the soil into the building, elevated levels of indoor radon can be expected in more permeable soil environments.

    2013-09-01

    The aim of the present study was to provide a preliminary insight into the diversity of tick-borne pathogens circulating at the domestic host-tick interface in Romania. For this, feeding and questing ticks were analyzed by real-time polymerase chain reaction (PCR) for the presence of Anaplasma phagocytophilum, Anaplasma platys, Ehrlichia canis, Borrelia burgdorferi sensu latu, and by PCR and subsequent sequencing for Rickettsia spp., Babesia spp. and Theileria spp. A total of 382 ticks, encompassing 5 species from 4 genera, were collected in April-July 2010 from different areas of Romania; of them, 40 were questing ticks and the remainder was collected from naturally infested cattle, sheep, goats, horses or dogs. Tick species analyzed included Ixodes ricinus, Dermacentor marginatus, Hyalomma marginatum, Rhipicephalus bursa, and Rhipicephalus sanguineus. Four rickettsiae of the spotted fever group of zoonotic concern were identified for the first time in Romania: Rickettsia monacensis and Rickettsia helvetica in I. ricinus, and Rickettsia slovaca and Rickettsia raoultii in D. marginatus. Other zoonotic pathogens such as A. phagocytophilum, Borrelia afzelii, and Babesia microti were found in I. ricinus. Pathogens of veterinary importance were also identified, including Theileria equi in H. marginatum, Babesia occultans in D. marginatus and H. marginatum, Theileria orientalis/sergenti/buffeli-group in I. ricinus and in H. marginatum and E. canis in R. sanguineus. These findings show a wide distribution of very diverse bacterial and protozoan pathogens at the domestic host-tick interface in Romania, with the potential of causing both animal and human diseases.

    Little information is available about the seroprevalence of Toxoplasma gondii and Neospora caninum infections in goats in Romania and even in Europe. During 2007-2010, 735 serum samples were collected from dairy goats located in 4 historical regions (Crişana, Maramureş, Transylvania and Muntenia) of Romania. Sera were analyzed for T. gondii and N. caninum antibodies (IgG type) by enzyme-linked immunosorbent assay (ELISA) using two commercial kits (Chekit Toxotest Antibody ELISA and Chekit Neospora caninum Antibody ELISA; Idexx-Bommeli, Switzerland). Three hundred and eighty-eight out of 735 (52.8%) goats presented T. gondii antibodies and 12 out of 512 (2.3%) goats had N. caninum antibodies. The high seroprevalence of T. gondii suggests that infection with this parasite is common in dairy goats in Romania, and less common the infection with N. caninum. This is the first time that infection with N. caninum in goats has been reported in Romania and the first extended study on seroepidemiology of T. gondii.

  3. Phylodynamics of HIV-1 subtype F1 in Angola, Brazil and Romania.

    PubMed

    Bello, Gonzalo; Afonso, Joana Morais; Morgado, Mariza G

    2012-07-01

    The HIV-1 subtype F1 is exceptionally prevalent in Angola, Brazil and Romania. The epidemiological context in which the spread of HIV occurred was highly variable from one country to another, mainly due to the existence of a long-term civil war in Angola and the contamination of a large number of children in Romania. Here we apply phylogenetic and Bayesian coalescent-based methods to reconstruct the phylodynamic patterns of HIV-1 subtype F1 in such different epidemiological settings. The phylogenetic analyses of HIV-1 subtype F1 pol sequences sampled worldwide confirmed that most sequences from Angola, Brazil and Romania segregated in country-specific monophyletic groups, while most subtype F1 sequences from Romanian children branched as a monophyletic sub-cluster (Romania-CH) nested within sequences from adults. The inferred time of the most recent common ancestor of the different subtype F1 clades were as follow: Angola=1983 (1978-1989), Brazil=1977 (1972-1981), Romania adults=1980 (1973-1987), and Romania-CH=1985 (1978-1989). All subtype F1 clades showed a demographic history best explained by a model of logistic population growth. Although the expansion phase of subtype F1 epidemic in Angola (mid 1980s to early 2000s) overlaps with the civil war period (1975-2002), the mean estimated growth rate of the Angolan F1 clade (0.49 year(-1)) was not exceptionally high, but quite similar to that estimated for the Brazilian (0.69 year(-1)) and Romanian adult (0.36 year(-1)) subtype F1 clades. The Romania-CH subtype F1 lineage, by contrast, displayed a short and explosive dissemination phase, with a median growth rate (2.47 year(-1)) much higher than that estimated for adult populations. This result supports the idea that the AIDS epidemic that affected the Romanian children was mainly caused by the spread of the HIV through highly efficient parenteral transmission networks, unlike adult populations where HIV is predominantly transmitted through sexual route.

  4. Community Perception of Water Quality in a Mining-Affected Area: A Case Study for the Certej Catchment in the Apuseni Mountains in Romania

    Mining-contaminated sites and the affected communities at risk are important issues on the agenda of both researchers and policy makers, particularly in the former communist block countries in Eastern Europe. Integrated analyses and expert based assessments concerning mining affected areas are important in providing solid policy guidelines for environmental and social risk management and mitigation. Based on a survey for 103 households conducted in a former mining site in the Certej Catchment of the Apuseni Mountains, western Romania, this study assesses local communities’ perceptions on the quality of water in their living area. Logistic regression was used to examine peoples’ perception on the quality of the main river water and of the drinking water based on several predictors relating to social and economic conditions. The results from the perception analysis were then compared with the measurements of heavy metal contamination of the main river and drinking water undertaken in the same study area. The findings indicate that perception and measurement results for the water quality in the Certej Catchment are convergent, suggesting an obvious risk that mining activities pose on the surface water. However, the perception on drinking water quality was little predicted by the regression model and does not seem to be so much related to mining as to other explanatory factors, such as special mineralogy of rock and soils or improper water treatment infrastructure, facts suggested by the measurements of the contaminants. Discussion about the implications of these joint findings for risk mitigation policies completes this article.

  5. The use of computational models to predict response to HIV therapy for clinical cases in Romania

    Introduction A major challenge in Romania is the optimisation of antiretroviral therapy for the many HIV-infected adults with, on average, a decade of treatment experience. The RDI has developed computational models that predict virological response to therapy but these require a genotype, which is not routinely available in Romania. Moreover the models, which were trained without any Romanian data, have proved most accurate for patients from the healthcare settings that contributed the training data. Here we develop and test a novel model that does not require a genotype, with test data from Romania. Methods A random forest (RF) model was developed to predict the probability of the HIV viral load (VL) being reduced to <50 copies/ml following therapy change. The input variables were baseline VL, CD4 count, treatment history and time to follow-up. The model was developed with 3188 treatment changes episodes (TCEs) from North America, Western Europe and Australia. The model’s predictions for 100 independent TCEs from the RDI database were compared to those of a model trained with the same data plus genotypes and then tested using 39 TCEs from Romania in terms of the area under the ROC curve (AUC). Results When tested with the 100 independent RDI TCEs, the AUC values for the models with and without genotypes were 0.88 and 0.86 respectively. For the 39 Romanian TCEs the AUC was 0.60. However, when 14 cases with viral loads that may have been between 50 and 400 copies were removed, the AUC increased to 0.83. Discussion Despite having been trained without data from Romania, the model predicted treatment responses in treatment-experienced Romanian patients with clade F virus accurately without the need for a genotype. The results suggest that this approach might be generalisable and useful in helping design optimal salvage regimens for treatment-experienced patients in countries with limited resources where genotyping is not always available.

    The diverse tick fauna as well as the abundance of tick populations in Romania represent potential risks for both human and animal health. Spotted fever group (SFG) rickettsiae are recognized as important agents of emerging human tick-borne diseases worldwide. However, the epidemiology of rickettsial diseases has been poorly investigated in Romania. In urban habitats, companion animals which are frequently exposed to tick infestation, play a role in maintenance of tick populations and as reservoirs of tick-borne pathogens. Therefore, the aim of the present study was to investigate the occurrence of SFG rickettsiae in ticks infesting dogs in a greater urban area in South-eastern Romania. Adult ixodid ticks (n=205), including Rhipicephalus sanguineus sensu lato (n=120), Dermacentor reticulatus (n=76) and Ixodes ricinus (n=9) were collected from naturally infested dogs and were screened for SFG rickettsiae using conventional PCR followed by sequencing. Additionally, ticks were screened for DNA of Babesia spp., Hepatozoon spp., Ehrlichia canis, and Anaplasma platys. Four zoonotic SFG rickettsiae were identified: Rickettsia raoultii (16%) and Rickettsia slovaca (3%) in D. reticulatus, Rickettsia monacensis (11%) in I. ricinus, and Rickettsia conorii (0.8%) in Rh. sanguineus s.l. Moreover, pathogens of veterinary importance, such as B. canis (21%) in D. reticulatus and E. canis (7.5%) in Rh. sanguineus s.l. were identified. The findings expand the knowledge on distribution of SFG rickettsiae as well as canine pathogens in Romania. Additionally, this is the first report describing the molecular detection of R. conorii in ticks from Romania. PMID:26507182

    The diverse tick fauna as well as the abundance of tick populations in Romania represent potential risks for both human and animal health. Spotted fever group (SFG) rickettsiae are recognized as important agents of emerging human tick-borne diseases worldwide. However, the epidemiology of rickettsial diseases has been poorly investigated in Romania. In urban habitats, companion animals which are frequently exposed to tick infestation, play a role in maintenance of tick populations and as reservoirs of tick-borne pathogens. Therefore, the aim of the present study was to investigate the occurrence of SFG rickettsiae in ticks infesting dogs in a greater urban area in South-eastern Romania. Adult ixodid ticks (n=205), including Rhipicephalus sanguineus sensu lato (n=120), Dermacentor reticulatus (n=76) and Ixodes ricinus (n=9) were collected from naturally infested dogs and were screened for SFG rickettsiae using conventional PCR followed by sequencing. Additionally, ticks were screened for DNA of Babesia spp., Hepatozoon spp., Ehrlichia canis, and Anaplasma platys. Four zoonotic SFG rickettsiae were identified: Rickettsia raoultii (16%) and Rickettsia slovaca (3%) in D. reticulatus, Rickettsia monacensis (11%) in I. ricinus, and Rickettsia conorii (0.8%) in Rh. sanguineus s.l. Moreover, pathogens of veterinary importance, such as B. canis (21%) in D. reticulatus and E. canis (7.5%) in Rh. sanguineus s.l. were identified. The findings expand the knowledge on distribution of SFG rickettsiae as well as canine pathogens in Romania. Additionally, this is the first report describing the molecular detection of R. conorii in ticks from Romania.

    Canine babesiosis is a tick-borne disease caused by the protozoa Babesia spp. that affects dogs worldwide. In Romania, canine babesiosis has become quite frequent in the last few years, with a wide variety of clinical signs, ranging from mild, nonspecific illness to peracute collapse, and even death. Traditionally, a Babesia infection in dogs is diagnosed based on the morphologic appearance of the intraerythrocytic piroplasms observed in peripheral blood smears. To date, no data on genetic characterization of Babesia species in dogs has been documented for Romania. Therefore, a molecular survey on natural Babesia infections of dogs in Romania using polymerase chain reaction and genetic sequence analysis of a fragment of the ssRNA gene was performed. A total number of 16 blood samples were tested for the presence of Babesia DNA. Blood samples were collected from 11 dogs with symptoms of babesiosis and microscopically proven positive for Babesia and from a group of five asymptomatic dogs, not tested microscopically for Babesia, which were included in the study for comparative analysis. The piroplasm-specific PCR amplifying the partial 18S rRNA gene confirmed Babesia spp. infection in all 11 samples from dogs with clinical babesiosis, and in one of the clinically normal dogs. Sequence analysis revealed the presence of Babesia canis in all clinically affected dogs and Babesia vogeli in one clinically normal dog. This is the first molecular evidence of B. canis and B. vogeli in dogs from Romania. The results of the study provide basic information toward a better understanding of the epidemiology of canine babesiosis in Romania and will help to promote an effective control program.

    Starting with 2002 the National Institute for Earth Physics (NIEP) has developed its real-time digital seismic network. This network consists of 96 seismic stations of which 48 broad band and short period stations and two seismic arrays are transmitted in real-time. The real time seismic stations are equipped with Quanterra Q330 and K2 digitizers, broadband seismometers (STS2, CMG40T, CMG 3ESP, CMG3T) and strong motions sensors Kinemetrics episensors (+/- 2g). SeedLink and AntelopeTM (installed on MARMOT) program packages are used for real-time (RT) data acquisition and exchange. The communication from digital seismic stations to the National Data Center in Bucharest is assured by 5 providers (GPRS, VPN, satellite communication, radio lease line and internet), which will assure the back-up communications lines. The processing centre runs BRTT's AntelopeTM 4.10 data acquisition and processing software on 2 workstations for real-time processing and post processing. The Antelope Real-Time System is also providing automatic event detection, arrival picking, event location and magnitude calculation. It provides graphical display and reporting within near-real-time after a local or regional event occurred. Also at the data center was implemented a system to collect macroseismic information using the internet on which macro seismic intensity maps are generated. In the near future at the data center will be install Seiscomp 3 data acquisition processing software on a workstation. The software will run in parallel with Antelope software as a back-up. The present network will be expanded in the near future. In the first half of 2009 NIEP will install 8 additional broad band stations in Romanian territory, which also will be transmitted to the data center in real time. The Romanian Seismic Network is permanently exchanging real -time waveform data with IRIS, ORFEUS and different European countries through internet. In Romania, magnitude and location of an earthquake are now

    Our laboratory measured the radionuclide presence in Transylvania region both after Chernobyl and Fukushima accidents. The paper presents old and new data connected with these disasters obtained not only by us but also by others laboratories from Romania. It is an attempt to mark the mainly aspects regarding the radioactive contamination in our country connected with these catastrophes. After the Chernobyl accident the radioactive cloud passage over Romania on NE - SW direction brought relatively intesive radionuclide deposition. On this direction the highest deposition were found in the areas where this passage during April 30-st and May 1-st were accompanied by rainfalls. In the rain water and fresh sediment colected at May 1-st, 1986 and measured the next days, all radionuclide species from Chernobyl could be identified [1]. Additional measurements of 90Sr and 239/240Pu have been made several years later in different environmental samples (roof sediment, soil, pollen, sand, roof-water, street dust) collected in 1986 from Cluj-Napoca, Romania [2]. In the case of Fukushima disaster the air transport from west and north-west brought small quantities of radionuclides over the Romanian teritorry. Even if in this case the radioactive cloud was very dilluted, 131I could be clearly identified and measured in air, rain water and other products as: milk, vegetables, grass, fresh meat from the NW of Romania [3]. Measurements have been also conducted in Bucharest and Pitesti. During the last 5 years suplimentary 137Cs measurements were made in different areas as an attempt to use this radionuclide as soil and sediment tracer. [1]. C.

    Crohn's disease is a chronic inflammatory condition, which may affect any portion of the digestive tract from the mouth to the anus. It is a chronic medical condition which requires surgery when medical treatment fails or complications such as strictures, sepsis or fistulation develop (1,2,3). We retrospectively studied a group of 19 patients with Crohn's disease from "Coltea" Hospital, Bucharest, Romania, and another group of 16 patients with Crohn's disease from Bedford Hospital UK, all of them having undergone surgery; we compared their preoperative and postoperative treatments, including follow up.It was concluded that the implementation of clinical guidelines and protocols for the management of patients with Crohn's disease is needed in Romania.

    In 1870 the Romanian physician Nicolae G. Chernbach published a photographic atlas of the main types of mental alienation, a collection of twelve plates depicting mentally ill patients from the Marcutza Asylum in Bucharest. Each photograph included a diagnosis based on the clinical nosography and theories of the physiognomy of insanity acknowledged during the period. The publication of the atlas--just a few years after Hugh W. Diamond's initial use of photography for this purpose in Britain in the 1850s--means that the photographs were not only the first taken in Romania, but among the first photographs of the mentally ill. This study provides an insight into the origins of modern clinical psychiatry and medical advances in Romania, and the contemporary personalities in Romanian and Eastern European medicine.

    The black sand of the Chituc marine sand bank, northern of the city of Navodari (Romania), presents anomalous high radioactivity. Field measurements recorded in some places dose rate up to 200 nSv/h, significantly overpassing the average value of 44 ± 20 nSv/h along the entire Southern sector of Romanian Black Sea shore. Gamma ray spectrometry performed on both Slanic-Prahova Underground Low Background Laboratory and Geological Institute of Romania Radiometric Facilities showed with clarity the dominance of (228)Ac radioisotope in the 50 microns fraction together with the (226)Ra and traces of (40)K. No significant amount of anthropogenic (137)Cs was identified. Based on radiometric as well as on SEM-EDAX and XRD determinations we come to the conclusion that the evidenced radioactivity could be attributed to both uranium and thorium series in the zircon and monazite fractions and to a lesser extent to potassium in the feldspars.

    In the last 20 years, particularly in the Eastern part of Romania, anthropogenic unreasonable and aggressive actions corroborated with soil water erosion, accentuated the processes of environmental degradation and decreased the productive potential of the soilscapes. This research starts from the practical necessity to increase the functional efficiency of these soilscapes, through the assessment of the risk factors, for diminishing the negative impact of degradation. The target is to develop a Sustainable Management Plan based of a general matrix description of the environmental factors in the Eastern part of Romania, to intervene (in terms of scientific, technological, administrative-economical and managerial aspects) for the ecological rehabilitation of the soilscapes. Thus, the research has an applicative character, establishing the measures for decreasing soil vulnerability to degradation and increasing the soil resilience.

Erosion, landslides, salinization, gleysation, and loss of humus are the main forms of soil deterioration in that region. This factsheet deals with the role of organic matter in soil productivity and the effects of various management practices and abandonment of the lands on soil organic matter. Soils in Transylvania Plain are analyzed concerning the amount of humus they contain. The influence of soil texture, climatic variables, and soil management on the qualitative soil humus content was studied in the top 20 cm of different managed loess soils of more then 100 profiles along a climosequence in that region. Taken together, soil, landform, land use and vegetation data suggest: (1) summit positions are relatively stable with immobilizing humus environments; (2) the content of humus increase progressively down steep at the contact with the floodplains; 3) without the influx of organic materials, erodible backslopes may become humus depleted as it happen the poor inputs of grassland and forest litter are mixed with surface soil horizon; 4) influx of mixed sediment and organic materials from backslopes maintains concentrations of humus on footslopes and toeslopes. This influence was more pronounced in the heavy clayey soils, suggesting that the accumulation of humus was enhanced by organo-mineral interactions. Entrenchment of drainage ways can circumvent these translocation processes. The results underscore the importance of functional connectivity between upland

    Neospora caninum, a coccidian parasite closely related to Toxoplasma gondii, is one of the major causes of abortion in cattle worldwide. Conventional serological techniques, such as the indirect fluorescent antibody test and enzyme-linked immunosorbent assay (ELISA), are routinely used in adult animals and aborted fetuses for the detection of anti- N. caninum antibodies. In Romania, infection with N. caninum in cattle has been reported recently, but only in limited areas from the north and central parts of the country. Therefore, the aim of this study was to obtain additional seroepidemiological data on infection with N. caninum on dairy farms from the south of Romania. A total of 258 blood samples was analyzed from 230 dairy cows and 28 calves from 9 dairy farms in southern Romania; the presence of specific IgG antibodies against N. caninum was determined using an indirect ELISA test. The average seroprevalence was 40.3%, but the within-herd prevalence ranged between 11.5 and 80.0%; the seroprevalence in dairy cows was 41.7%, while in calves it was 28.6%. Of the positive samples, 74.0% (77/104) had a high positive reaction (S/P ratio more than 1.0), while 26.0% (27/104) had a low positive reaction (S/P ratio between 0.5 and 1.0). This study indicates that N. caninum infection is widespread in the south of Romania, which could explain the causes of abortions registered in some herds in the studied area. However, a serological screening across the country is planned in order to assess the actual national prevalence of N. caninum infection, followed by implementation of a prevention and control program.

    A selection of 167 Corynebacterium diphtheriae strains isolated in Romania, the Russian Federation and the Republic of Moldova were analysed by biotyping, phage typing, the toxin production test and by molecular techniques such as ribotyping, pulsed field gel electrophoresis and random amplified polymorphic DNA, in order to establish the epidemiological relatedness, genetic divergence and strain circulation within and between the bordering countries. Using a set of five digoxigenin-labeled oligonucleotides and BstEII digestion, 34 ribotypes were identified. The strains isolated in the epidemic areas (Russia and Moldova) were very closely related but different from those isolated in Romania. C1 and C5 were the main ribotypes identified in these areas. Neither ribotype was found in Romania, where the main circulating types were C3 and C7. Field inversion gel electrophoresis was more discriminative than ribotyping and revealed 54 macrorestriction profiles after SfiI restriction. Both methods showed a significant homogeneity of the strains from epidemic areas and a large diversity among the Romanian strains. Random amplification was useful as an identification method for the epidemic strains, but not for the Romanian ones which displayed a large number of amplification profiles. The phenotypic methods associated with molecular typing techniques enabled distinguishing between strains, detecting the epidemic clone, and sustaining the absence of transmission across borders.

    Malnutrition is a prevalent condition in hospitalized children. Our aims were to evaluate the nutritional state and to validate the STRONGkids risk assessment tool in a hospitalized paediatric population in Romania. This is a prospective single-centre study in a tertiary teaching hospital in Romania (May 2011-January 2012). We calculated the STRONGkids score and measured the children's height and weight. Standard deviation <-2 for weight-for-height and height-for-age was considered to indicate acute or chronic malnutrition respectively. Two hundred seventy-one children were included, with median age of 5.2 years and median hospital stay of 2.01 days. Prevalence of malnutrition and severe malnutrition was 37% and 15% respectively. Using the STRONGkids screening tool, 58% of the children were found at risk of malnutrition (24% were at high risk). The kappa coefficient of agreement between STRONGkids and WHO malnutrition classification was 0.61. When a low serum protein level was used in upgrading STRONGkids risk category, kappa increased significantly to 0.71 (p=0.001). A modified STRONGkids score, incorporating total serum protein levels, performs well in predicting malnutrition in hospitalized paediatric population in Romania. PMID:24847598

    Romania is one of the countries with the highest prevalence of methicillin-resistant Staphylococcus aureus (MRSA) in the world. To obtain data on affiliation of MRSA to strains and clonal complexes and on the population of methicillin susceptible S. aureus (MSSA), clinical isolates from bloodstream infections, skin and soft tissue infections as well as from screening swabs were collected at hospitals in Ia?i, a city in the North-Eastern part of Romania. Isolates were characterised by microarray hybridisation. Nearly half of all isolates (47%), and about one third (34%) of bloodstream isolates were MRSA. The prevalence of the Panton-Valentine leukocidin (PVL) was also high (31% among MRSA, 14% among MSSA). The most common MRSA strain was a PVL-negative CC1-MRSA-IV that might have emerged locally, as a related MSSA was also common. PVL-positive CC8-MRSA-IV (“USA300”) and PVL-negative ST239-like MRSA-III were also frequently found while other MRSA strains were only sporadically detected. Among MSSA, PVL-positive CC121 as well as PVL-negative CC1, CC22 and CC45 predominated. Although this study provides only a snapshot of S. aureus/MRSA epidemiology in Romania, it confirms the high burden of MRSA and PVL on Romanian healthcare settings. PMID:24846009

    In a European context marked by heterogeneous Assisted Reproductive Technology (ART) practices, this article will elucidate and compare the norm elaboration processes pertaining to ART in France and Romania. Using an experimental five-phase model encompassing experimentation, excesses, social mobilization, legislation and contestation, I will examine the processes linking micro (everyday medical practices), meso (institutional regulation) and macro (legislation) levels of ART bioethics in the two countries since the 1980s. ART has developed in France and Romania on different time frames, and Romania's management of ART is decisively influenced by Ceauşescu's pro-natalist policy. However, I will show how the two countries share similar trajectories along the proposed model's first three phases of norm elaboration, and, in recent years, how both have witnessed the emergence of social actors' claims for a more liberal and state-sponsored access to ART, requiring a redefinition of bioethics in line with reproductive social justice at national levels. This is fed by contemporary medical practices and social values, and an increasing transnational interconnectedness between social actors.

    This study presents the first characterization of carbapenem-non-susceptible Klebsiella pneumoniae isolates by means of a structured six-month survey performed in Romania as part of an Europe-wide investigation. Klebsiella pneumoniae clinical isolates from different anatomical sites were tested for antibiotic susceptibility by phenotypic methods and confirmed by PCR for the presence of four carbapenemase genes. Genome macrorestriction fingerprinting with XbaI was used to analyze the relatedness of carbapenemase-producing Klebsiella pneumoniae isolates collected from eight hospitals. Among 75 non-susceptible isolates, 65 were carbapenemase producers. The most frequently identified genotype was OXA-48 (n = 51 isolates), eight isolates were positive for blaNDM-1 gene, four had the blaKPC-2 gene, whereas two were positive for blaVIM-1. The analysis of PFGE profiles of OXA-48 and NDM-1 producing K. pneumoniae suggests inter-hospitals and regional transmission of epidemic clones. This study presents the first description of K. pneumoniae strains harbouring blaKPC-2 and blaVIM-1 genes in Romania. The results of this study highlight the urgent need for the strengthening of hospital infection control measures in Romania in order to curb the further spread of the antibiotic resistance.

    Lineage 2 West Nile virus (WNV), previously found only in sub-Saharan Africa and Madagascar, was identified in Hungary in 2004 and has rapidly expanded in Europe in the past decade. Following a significant outbreak of West Nile fever with neurological cases caused by lineage 1 WNV in Romania in 1996, scattered cases have been recorded in the south-east of the country in each transmission season. Another outbreak, affecting a larger area and caused by lineage 2 WNV, was recorded in 2010. We analysed human sera from neuroinvasive West Nile fever cases and mosquitoes, sampled in south-eastern Romania between 2011 and 2013, for the presence of WNV genome, and obtained partial NS5 and envelope glycoprotein sequences. Human- and mosquito-derived WNV sequences were highly similar (99%) to Volgograd 2007 lineage 2 WNV and differed from isolates previously detected in central and southern Europe. WNV was detected in one pool of Culex pipiens s.l. males, documenting vertical transmission. Lineage 4 WNV, of unknown pathogenicity to mammals, was found in the amphibian-feeding mosquito Uranotaenia unguiculata from the Danube Delta. Our results present molecular evidence for the maintenance of the same isolates of Volgograd 2007-like lineage 2 WNV in south-eastern Romania between 2011 and 2013.

    3D geologic modelling is a modern tool which allow the conceptualization of geologic relations in an interactive environment, strengthening the ability to understand and present tectonic and structural geologic models. We integrated the data available in the literature (wells, maps, cross-sections) for the geological structure of the Eastern Romania, comprising the Eastern Carpathians Orogen and its foreland. The subducting East European plate generated the Eastern Carphatians thrusts. Under the Eastern Carpathians, beside East European plate, the Tornquist-Teysseire zone is caught. East European Craton (Proterozoic), Scythian Platform (Paleozoic), North Dobrogean Orogen (Paleozoic) and Moesian Platform (Paleozoic), all neighbor Tornquist-Teysseire zone (Paleozoic), playing the role of foreland for the Eastern Carpathian Orogen. The Eastern Carphatians Orogen has two flysch belts, the Inner Carpathian called Dacides formed in Cretacic deformations and the Outer Carpathian called Moldavides and formed in Late Badenian to Sarmatian deformations. The modelling was performed in Midland Valley's Move software. The boundaries of all the structural units presented above were modelled, together with the faults which are represented on the various osurces used. The created 3D geological model is seen as a tool to better understand and represent the tectonic and structural model of the Eastern ROmania and will also allow a better quantification of the relations between geology and landforms in Eastern Romania.

    Molecular characterisation of measles virus is a powerful tool for tracing transmission. Genotyping may prove the absence of endemic circulation of measles virus, i.e. transmission for more than 12 months, which is one of the criteria for verifying elimination of the disease. We have genetically characterised measles viruses detected in Romania from 2008 to 2012, focusing on the recent outbreaks from 2010 to 2012 that affected mainly groups with limited access to healthcare and schools. The findings emphasise the importance of genotyping during the different phases of an outbreak. A total of 8,170 cases were notified, and 5,093 (62%) of the 7,559 possible cases were serologically confirmed. RT-PCR was performed for 104 samples: from the 101 positive samples obtained from sporadic measles cases or clusters from different counties, 73 were genotyped. Sporadic measles cases associated with D4 and D5 viruses were observed from2008 to 2009. Genotype D4-Manchester was predominant in 2011 and 2012. In addition, the related variant D4-Maramures and MVs/Limoges.FRA/17.10[D4] and a few D4-Hamburg strains were detected. The detection of several distinct MV-D4 genotypes suggests multiple virus importations to Romania. The outbreak associated with D4 genotype is the second largest outbreak in Romania in less than 10 years.

    Neosporosis is a disease that mainly affects cattle in both dairy and beef herds. The main definitive host of this parasite is the dog. Since 1984 and its first description a large number of data were published worldwide on this parasite. In Romania, the research regarding this parasite is limited. The purpose of this study was to determine the seroprevalence of Neospora caninum infection in dairy cattle from six regions in north-western Romania and to evaluate the intensity of infection in different animals groups. A total number of 901 samples (862 sera from adult cows and 39 sera from calves) were collected from dairy farms and were screened for the presence of specific IgG anti-bodies using an enzyme-linked immunosorbent assay (ELISA). The overall seroprevalence for neosporosis was 34.6%. In adult cows and calves seroprevalences reached 34.8% (300/862) and 30.8% for calves (12/39) respectively. In cattle which had previously aborted, seroprevalence was 40.9%. These results indicate that N. caninum infection is widespread among animals reared in dairy systems from Romania and a program for farmer training and a strategy for reducing the economic impact of the disease are needed.

The obtained data will be modeled considering the known data in order to reconstruct water discharge (Q), suspended sediments (Qs) This application was elaborated for Eastern part of Romania, covered by the hydrographic basins of Siret and Prut, respectively for an area of more than 43000 km2. The conditions for geological structure, relief, land use, etc. offers the potential to better understand the spatial variability of some natural processes behavior in the last 6 decades. Also, a number of human interventions have occurred within the Siret and Prut River's drainage basins (i.e., dam construction, channelization, sediment mining, and deforestation), primarily during the past century. The history of human interventions in the area began during the twentieth century with the construction of bank protection structures, especially following the catastrophic 1970-1975 flood events. Natural reforestation, which followed several centuries of intense deforestation, has been most intense from the 1950s onward.

    Background and aims The most common thyroid disorders, with an increasing detection worldwide, are the thyroid nodules and thyroiditis, which leads to an increase of thyroid cancer incidence . In two different countries with a different exposure to risk factors for thyroid cancer, such as Cyprus and Romania, the rank of thyroid cancer among other neoplasms is very different: the 3rd most prevalent cancer among females in Cyprus and the 12th in Romania, respectively. Environmental chemicals, such as bisphenol A have a proven effect on the thyroid function. However, the relation between the exposure to the endocrine disruptor and the development of thyroid nodules, with a potential of malignant transformation has not been previously studied. The aim of the study was to investigate the potential factors that lead to the difference of thyroid nodules incidence in the mentioned countries. Methods A pilot case-control study has been conducted in 2014–2015 in the “Prof. Dr. Ion Chiricuţă” Institute of Oncology, Cluj-Napoca, Romania and the Endocrinology Department of Archbishop Makarios III Hospital, Nicosia, Cyprus. Females older than 20 years with no medical history were recruited. Cases were women with ultrasound-confirmed thyroid nodules of size >3mm. Controls were women without thyroid nodules after ultrasound confirmation. All participants provided blood samples for measurements of the thyroid stimulating hormone (TSH), free thyroxin (FT4), anti-thyroglobulin (ATg) and anti-thyroid peroxidase (ATPO); urine samples. Demographics, anthropometrics and other relevant information were provided through the administration of a questionnaire. Results In Romania we selected 51 patients with thyroid nodules (case group) and 41 without thyroid nodules (control group) and in Cyprus 57 cases, respectively 65 controls. After the statistical analysis of the data collected we observed statistically significant differences between the populations of the two countries

  18. Stable isotope distribution in precipitation in Romania and its relevance for palaeoclimatic studies

    A surge of recent studies in Romania have targeted various aspects of palaeoclimate (based on stable isotopes in ice, speleothems, tree rings), mineral water origin, wine and other juices provenance. However, while much needed, these studies lack a stable isotope in precipitation background, with only two LMWL's being published so far. In this paper we discuss the links between the stable isotopic composition of precipitation (δ18O and δ2H), climate (air temperature, precipitation amount and large scale circulation) and their relevance for the palaeocllimatic interpretation of stable isotope values in cave ice, cryogenic calcite and tree rings from different sites in Romania. Most of the precipitation in Romania is delivered by the Westerlies, bringing moisture from the North Atlantic; however, their influence is greatly reduced in the eastern half of the country where local evaporative sources play an important role in the precipitation balance. The SW is dominated by water masses from the Mediterranean Sea, while the SE corner clearly draws most of the moisture from the Black Sea and strongly depleted North Atlantic vapor masses. In 2012, Romania experienced the worst draught in 60 years, possibly due to a northward shift of the jest stream associated to blocking conditions in summer, which led to a more northern penetration of the Mediterranean-derived air masses, as well increased precipitation of re-evaporated waters. We have further analyzed cave drip water (δ18O and δ2H), cryogenic cave calcite (δ18O and δ13C) and tree rings (δ18O and δ13C) from selected sites across NW Romania, where the water isotopes in precipitation showed the best (and easiest to understand, given the climatic conditions in 2012) correlation with climatic parameters. Our results that 1) δ18O and δ2H in cave ice are a good proxy for late summer through early winter air temperature; 2) δ13C in cryogenic cave calcite are possible indicators of soil humidity and 3) δ18O in pine

    We have studied with the students our climate variability in the last 55 years (1956-2010) to better understanding the feedback between the interlinked terrestrial and atmospheric processes on different spatial and temporal scales. We did case studies of regional hydrological behavior in climate sensitive and drought or flood regions in the North-East of Romania. In the classroom at the "Costache Negruzzi" National College Iasi we have studied with our students, aged 14-18 years old, the temporal and spatial distribution of the precipitation and the temperature in a 55 years period, between 1956-2010, in the North-East of Romania, especially at the meteorological station in Iaši. We did graphs with the observational data from the National Meteorological Agency of Romania about precipitation and air-temperature in our region climate and we have registered our own data with an automatic meteorological station placed in the "Costache Negruzzi" schoolyard. In the classroom we have represented the annual medium precipitation and the temperature variability in graphics registered between 1970-2010, in the area of Iasi-Moldavia, Romania. We have identified four dangerous levels of precipitation especially for flood and drought regions in the North-East of Romania. We have studied the maximal and minimal level of the daily, monthly and annual precipitation in correlation with the temperature variability graphs in the same area. We have realized with the students a very complex analysis on the frequency, repartition and variation in time of the precipitation and we have used the information in the Physics and Geography classes. The students aged 14-18 years old did computing statistics of the meteorological data and did different graphs for the precipitation intensity and frequency on special levels: medium, minimum and maximum. The students applied the data for annual precipitation level in each month, 1970-2010 period and discuss the results to identify the climate

    The U.S. Geological Survey defined the Moesian Platform Composite Total Petroleum System and the Dysodile Schist-Tertiary Total Petroleum System, which contain three assessment units, in the Carpathian-Balkanian Basin Province of Romania and Bulgaria. The Moesian Platform Assessment Unit, contained within the Moesian Platform Composite Total Petroleum System, is composed of Mesozoic and Cenozoic rocks within the Moesian platform region of southern Romania and northern Bulgaria and also within the Birlad depression in the northeastern platform area. In Romania, hydrocarbon sources are identified as carbonate rocks and bituminous claystones within the Middle Devonian, Middle Jurassic, Lower Cretaceous, and Neogene stratigraphic sequences. In the Birlad depression, Neogene pelitic strata have the best potential for generating hydrocarbons. In Bulgaria, Middle and Upper Jurassic shales are the most probable hydrocarbon sources. The Romania Flysch Zone Assessment Unit in the Dysodile Schist-Tertiary Total Petroleum System encompasses three structural and paleogeographic subunits within the Pre-Carpathian Mountains region: (1) the Getic depression, a segment of the Carpathian foredeep; (2) the flysch zone of the eastern Carpathian Mountains (also called the Marginal Fold nappe); and (3) the Miocene zone (also called the Sub-Carpathian nappe). Source rocks are interpreted to be Oligocene dysodile schist and black claystone, along with Miocene black claystone and marls. Also part of the Dysodile Schist-Tertiary Total Petroleum System is the Romania Ploiesti Zone Assessment Unit, which includes a zone of diapir folds. This zone lies between the Rimnicu Sarat and Dinibovita valleys and between the folds of the inner Carpathian Mountains and the external flanks of the Carpathian foredeep. The Oligocene Dysodile Schist is considered the main hydrocarbon source rock and Neogene black marls and claystones are likely secondary sources; all are thought to be at their maximum

    Among the many kinds of natural and man-made disasters, earthquakes dominate with regard to their social and economical impact on the urban environment. Global seismic hazard and vulnerability to earthquakes are steadily increasing as urbanization and development occupy more areas that are prone to effects of strong earthquakes. The assessment of the seismic hazard and risk is particularly important, because it provides valuable information for seismic safety and disaster mitigation, and it supports decision making for the benefit of society. Romania and Bulgaria, situated in the Balkan Region as a part of the Alpine-Himalayan seismic belt, are characterized by high seismicity, and are exposed to a high seismic risk. Over the centuries, both countries have experienced strong earthquakes. The cross-border region encompassing the northern Bulgaria and southern Romania is a territory prone to effects of strong earthquakes. The area is significantly affected by earthquakes occurred in both countries, on the one hand the events generated by the Vrancea intermediate-depth seismic source in Romania, and on the other hand by the crustal seismicity originated in the seismic sources: Shabla (SHB), Dulovo, Gorna Orjahovitza (GO) in Bulgaria. The Vrancea seismogenic zone of Romania is a very peculiar seismic source, often described as unique in the world, and it represents a major concern for most of the northern part of Bulgaria as well. In the present study the seismic hazard for Romania-Bulgaria cross-border region on the basis of integrated basic geo-datasets is assessed. The hazard results are obtained by applying two alternative approaches - probabilistic and deterministic. The MSK64 intensity (MSK64 scale is practically equal to the new EMS98) is used as output parameter for the hazard maps. We prefer to use here the macroseismic intensity instead of PGA, because it is directly related to the degree of damages and, moreover, the epicentral intensity is the original

    Hemorrhagic fever with renal syndrome (HFRS) has been confirmed by serological methods during recent years in Romania. In the present study, focus-reduction neutralization tests (FRNT) confirmed Dobrava hantavirus (DOBV) as the causative agent in some HFRS cases, but could not distinguish between DOBV and Saaremaa virus (SAAV) infections in other cases. DOBV was detected by a DOBV-specific TaqMan assay in sera of nine patients out of 22 tested. Partial sequences of the M genomic segment of DOBV were obtained from sera of three patients and revealed the circulation of two DOBV lineages in Romania. Investigation of rodents trapped in Romania found three DOBV-positive Apodemus flavicollis out of 83 rodents tested. Two different DOBV lineages were also detected in A. flavicollis as determined from partial sequences of the M and S genomic segments. Sequences of DOBV in A. flavicollis were either identical or closely related to the sequences obtained from the HFRS patients. The DOBV strains circulating in Romania clustered in two monophyletic groups, together with strains from Slovenia and the north of Greece. This is the first evidence for the circulation of DOBV in wild rodents and for a DOBV etiology of HFRS in Romania.

    When speaking about Professor Gheorghe Bilaşcu (1863–1926) and his major contribution to the establishment of Romanian medical education in Cluj, he should be considered not only in terms of scientist and creator of the Dental School, but also through his commitment to the development of science and culture in Romania. A wealthy dentist in Budapest where he graduated from the Dental School, he supported a lot of Romanian students to attend schools and universities in the Budapest, thus contributing to the development of culture in his own country. Finally, he left his private practice in the Capital of Hungary to come to Cluj to support the efforts of building the Dental School and profession in Romania. This paper illustrates the contribution that Professor Gheorghe Bilaşcu made to the development of higher education in Romania, as well as his support of the local culture. PMID:27547068

    The study aims to identify local communities perception and awareness in terms of hydro-meteorological extreme events in order to better understand the local context of vulnerability and communities resilience to flash floods as well as the mitigation measures undertaken by local authorities to cope with these phenomena. The study-area is located in the Bend Subcarpathians, Romania, a region well known for high tectonic mobility and dynamics of hydro-geomorphic processes (e.g. floods and flash floods, landslides). The study was conducted in the framework of VULMIN project (PN-II-PT-PCCA-2011-3.1-1587), funded by the Ministry of National Education for the period 2012-2016 (http://www.igar-vulmin.ro). The previous analyses conducted in the project showed a high exposure to flash floods of small river catchments (generally below 200 km2 ) located in the study-area (Teleajen-Buzau hydrographic area). Some of the most recent events (2005, 2008, 2010 and 2014) had a high impact on local communities in terms of important losses to their assets and psychological effects. Thus, in the summer 2014, a questionnaire-based survey was addressed to over 50 households (from 5 villages), significantly affected by flash floods and structured interviews were held with local authorities (local municipalities, county Civil Protection Inspectorates). The questionnaire was focused on the perception of human vulnerability to environmental change and extreme events, mainly floods, aiming to outline the personal experience, post-disaster rehabilitation, awareness, worrying and opinion on the measures aimed to prevent and mitigate the effects of flooding. The flash flood events are of major concern for local community, due to their high return period (1-5 years) and magnitude in the recent years. This influences also the population response and adaptive capacity to these events, which is limited to individual measures (e.g. buildings consolidations and relocations). The survey showed a

    The thick and continuous Mio-Pliocene sedimentary successions of the Focşani Depression in the Dacian Basin of Romania provide an excellent opportunity to study the paleoecological changes in the Eastern Paratethys during the time when the Mediterranean and Black Sea experienced major sea level fluctuations related to the closure and re-opening of the marine connection to the Atlantic Ocean during the Messinian Salinity Crisis. These successions form the basis of high-resolution magneto-biostratigraphic studies that allow a detailed correlation to the standard Geological Time Scale. Here, we analyze the paleoenvironmental evolution of the East Carpathian foredeep by integrating micro- and macropaleontological data and sedimentological analyses. The ostracod and mollusc fossil associations from the Râmnicu Sărat river section indicate that the late Maeotian depositional environment was characterized by shallow waters and littoral to fluvio-deltaic sediments. The Maeotian-Pontian boundary (6.04 Ma) is marked by a marine ingression, comprising benthic (agglutinated and calcareous) and planktonic (Streptochilus spp.) foraminifera and nanofossils. Following this marine ingression, the Lower Pontian (Odessian; 6.04-5.8 Ma) fauna shows an increased bathymetry of the basin. The presence of ostracod species with eye tubercles indicates depositional environments within the photic zone (< 100 m). The Middle Pontian (Portaferrian; 5.8-5.5 Ma) is marked by a widespread sea level lowering resulting in dominant fluvio-deltaic conditions. This ecostratigraphy demonstrates that the main Messinian sea-level draw down (at 5.6-5.5 Ma) occurred in mid-Portaferrian times. Paleoenvironmental indicators show that the water level in the Foçsani Depression dropped less than 100 m during Mediterranean desiccation. The Dacian Basin remained filled with water, suggesting a positive hydrological balance for the region. This is compatible with the presence of a shallow barrier at Dobrogea

    The Transylvanian Plain (TP) is a geographical region located in north-central Romania and is bordered by large rivers to the north and south, the Somes and the Mures, respectively. TP with an area of approx. 395,616 ha, includes areas of three counties (Cluj - CJ, Mures -MS, Bistrita-Nasaud - BN), has a predominantly agricultural character, and is characterized by hilly climate floor with oceanic influences, 6-10 0C average annual temperatures and 500-700 mm/year average annual precipitations. The presence of the Carpathian mountains ring and the arrangement, almost concentric, of the relief from Transylvanian Depression, determines the development of a zonal sequence of soil types, a horizontal zonality as a direct influence of lithology and indirect of the relief, by changing climate and vegetation. Diversity of the pedogenetical factors - highly fragmented relief, forest and herbaceous vegetation grafted on a lithological background predominantly acid in the north - west and predominantly basic in south - est, parent rock composition and especially their combination in the contact zones, have conditioned in this hilly area of TP a tessellated soil cover. During soil pedogenesis, soil properties and features developed in response to differential lithology and macro/microrelief. Evaluated soils were found to largely be a complex mix of Cernisols, Luvisols and Antrisols. Zoning cultures and establishing the optimum sowing periods was made after the observations arising from practice and after the results obtained in the agricultural experimental research stations. Climate changes in recent years and climate monitoring from TP offers the possibility to check the calendar for the optimum sowing period. Monitorization of the thermal and water regime from TP was performed with twenty HOBO microstations which determine the temperature (to a height of 1 m) and rainfalls, same as temperature (at 10, 30, 50 cm depth in soil) and soil moisture (at 10 cm depth).

    The intermediate-depth (70-180 km) earthquakes of the Vrancea (Romania) source zone produce the most significant seismic hazard to Romania and its neighboring countries, in particular to the Republic of Moldova, Ukraine, and Bulgaria. Analyses of the macroseismic data of these events revealed several peculiar effects, which can be summarized as follows: the earthquakes affect very large areas with predominantly NE-SW trending extensions, and, in many cases local and regional geological conditions control the variation of the amplitudes of ground motions to a larger degree than magnitude or distance. An extensive set of macroseismic data is now available for the four major earthquakes of the last century: November 10, 1940 (Mw = 7.7), March 4, 1977 (Mw = 7.4), August 30, 1986 (Mw = 7.2), and May 30, 1990 (Mw = 6.9). This study aims to achieve unified macroseismic data sets of these destructive Vrancea earthquakes. ‘Unified' means the application of a single but common intensity scale to the entire macroseismic field of each earthquake. Partly, site intensities had to be retrieved by tracing back to original investigations or even to the primary raw descriptions, when necessary and available. Concerning the data of the Romanian territory, major efforts were necessary to recover the macroseismic information. Due to the lack of access to original site observations or data-files, the information for every earthquake was retrieved by digitizing the original macroseismic maps compiled by different authors. Since decades the 1940 November earthquake has caused considerable confusion in distinguishing the macroseismic scales, applied by different authors. This paper proposes a way to solve these inconsistencies. Furthermore, we present MSK intensities and the corresponding isoseismals of the March 4, 1977, the August 30, 1986 and the May 30, 1990 Vrancea intermediate-depth earthquakes.

    In June 2009 Romania successfully completed the world’s first air shipment of highly enriched uranium (HEU) spent nuclear fuel transported in Type B(U) casks under existing international laws and without special exceptions for the air transport licenses. Special 20-foot ISO shipping containers and cask tiedown supports were designed to transport Russian TUK 19 shipping casks for the Romanian air shipment and the equipment was certified for all modes of transport, including road, rail, water, and air. In December 2009 Libya successfully used this same equipment for a second air shipment of HEU spent nuclear fuel. Both spent fuel shipments were transported by truck from the originating nuclear facilities to nearby commercial airports, were flown by commercial cargo aircraft to a commercial airport in Yekaterinburg, Russia, and then transported by truck to their final destinations at the Production Association Mayak facility in Chelyabinsk, Russia. Both air shipments were performed under the Russian Research Reactor Fuel Return Program (RRRFR) as part of the U.S. National Nuclear Security Administration (NNSA) Global Threat Reduction Initiative (GTRI). The Romania air shipment of 23.7 kg of HEU spent fuel from the VVR S research reactor was the last of three HEU fresh and spent fuel shipments under RRRFR that resulted in Romania becoming the 3rd RRRFR participating country to remove all HEU. Libya had previously completed two RRRFR shipments of HEU fresh fuel so the 5.2 kg of HEU spent fuel air shipped from the IRT 1 research reactor in December made Libya the 4th RRRFR participating country to remove all HEU. This paper describes the equipment, preparations, and license approvals required to safely and securely complete these two air shipments of spent nuclear fuel.

    Herbivorous animals are usually, by virtue of their diet, outside the major transmission cycles of Trichinella spp. However, since 1975, the year of the first report of human trichinellosis caused by the consumption of infected horse meat, the domestic horse has appeared as a novel vector of Trichinella spp. infection to humans, with 15 outbreaks documented in France and Italy. Romania, one of the main countries exporting horses into the European Union (EU), experienced a dramatic increase of Trichinella spp. infection in both domestic pigs and humans in the 1990s. Some Trichinella spiralis-infected horses were exported to the EU during this period. The aim of this study was to evaluate the prevalence of Trichinella spp. infections in horses from Romania using both direct and indirect tests. Of 3000 serum samples tested in 2001, none were positive by ELISA using three different Trichinella antigens (crude; excretory/secretory, ES; stg-BSA antigens). Of 2992 serum samples tested in 2002, 17 (0.56%) showed optical density values higher than the cut-off in an ELISA using ES antigens and one was confirmed by western blot (WB). Four of the 17 ELISA positive horses, including the horse with a confirmed serology by WB, were subjected for intensive meat examination at slaughter, but no Trichinella spp. larvae were detected. Further, no Trichinella spp. larvae were detected by trichinelloscopy and artificial digestion of 25,838 horses slaughtered in Alexandria and Timisoara between 2001 and 2004. The false positive results obtained by serology confirm the previous work on the unreliability of serology for detection of Trichinella spp. infection in horses. Furthermore, the lack of detection of Trichinella spp. infected horses by artificial digestion, suggests a very low prevalence of infection in horses in Romania.

    After reaching the lowest level of tuberculosis mortality rate in 1980, 3.7% hundred thousand (830 deaths), followed by a few years with low levels of mortality, the period following the year 1985 was marked by a gradual increase in the mortality rate and in 1995 it reached 11.3% hundred thousand (2560 deaths). The implementation since 1997 of TB control programmes on medium-term (under technical assistance of WHO experts) has led to a decrease in tuberculosis mortality rate to 1482 deaths, 6.9% hundred thousand, in 2010. Compared to standardized TB mortality rate in Europe, Romania is far from the countries of Western and Central Europe, with a rate 6.6 times greater than in the EU. Standardized mortality rate by sex reveals that the rate for males in Romania, in 2009, was 6.5 times higher than in women. Similar to 2009, in 2010, the deaths have reached a maximum per age group at 45-54 years old. In 2010 the tuberculosis fatality was 4.7% and the lethality was 0.6%. Consistency of tuberculosis control strategy, regarding both measures for early detection of tuberculosis and establishing TB treatment under the direct observation, represent the safety elements in the reduction of tuberculosis mortality rate. It should be reminded that one of the goals of Stop TB Partnership is reducing mortality rate in 2012 at half compared to 1990, Romania being one of the 18 countries included in this plan initiated by the WHO Europe Region Office.

    The oncogenic role of human papillomavirus (HPV) in triggering cervical cancer, the second most common cancer in women worldwide, is well established. Romania ranks in first place in Europe in terms of the incidence of cervical cancer. Geographical widespread data on HPV type-distribution are essential for estimating the impact of HPV vaccines and cervical cancer screening programmes. In this study we aimed to identify the prevalence of HPV genotypes and to establish correlations with abnormal cervical cytology among the female population of Brasov County, Romania. A total of 1,000 women aged 17.3-57 years, attending routine cervical examination in the Obstetrics and Gynecology Hospital of Brasov, Romania, and undergoing both cytological examination and HPV genotyping were screened. Infection with 35 different HPV genotypes was detected in 39.6% of cytological specimens. Overall HPV infections were highest in young women under 25 years (p<0.0001), in which cervical cytological abnormalities also reached the highest prevalence. Patients infected by HPV-16 or HPV-18 showed the highest prevalence of cervical cytological abnormalities. Some 48.2% of women with abnormal cytology were infected with high-risk HPV types whereas less than 3% of them were infected only with low-risk HPV types. Our study showed that the prevalence of high-risk HPV infection among Romanian women is higher compared to other studies in other geographic areas. Thus, we consider that in areas where there is an increased prevalence of high-risk HPV infections, HPV genotyping should be performed in all women aged between 18 and 45 years, and Pap test should be performed every 6 months in women with high-risk HPV infection, even those with previous normal cervical cytology.

    Around the world there are growing concerns for waste electrical and electronic equipment. This is motivated by the harmful effects of waste electrical and electronic equipment on the environment, but also by the perspectives of materials recovery. Differences between countries regarding waste electrical and electronic equipment management are notable in the European Union. Romania is among the countries that have made significant efforts to comply with European Union regulations, but failed reaching the collection target. The article presents a mini review of the waste electrical and electronic equipment management system in Romania, based on legislation and policy documents, statistical data, research studies and reports published by national and international organisations. The article debates subjects like legislative framework, the electrical and electronic equipment Romanian market, the waste electrical and electronic equipment collection system, waste electrical and electronic equipment processing and waste electrical and electronic equipment behaviour. The recast of the European directive brings new challenges to national authorities and to other stakeholders involved in the waste electrical and electronic equipment management. Considering the fact that Romania has managed a collection rate of roughly 1 kg capita(-1) in the last years, the new higher collection targets established by the waste electrical and electronic equipment Directive offer a serious challenge for the management system. Therefore, another aim of the article is to highlight the positive and negative aspects in the Romanian waste electrical and electronic equipment field, in order to identify the flows that should be corrected and the opportunities that could help improve this system to the point of meeting the European standards imposed by the European Directive.

    Landfill monitoring is one of the most important components of waste management. This article presents a case study on landfill monitoring using remote sensing technology. The study area was the Glina landfill, one of the largest municipal waste disposal sites in Romania. The methodology consisted of monitoring the differences of temperature computed for several distinct waste disposal zones with respect to a ground reference area, all of them located within the landfill site. The remote sensing data used were Landsat satellite multi-temporal data. The differences of temperature were computed using Landsat thermal infrared data. The study confirmed the use of multi-temporal Landsat imagery as a complementary data source.

    In the last two decades transition was a word used to describe the important mutations that have characterized social and economic structures in Romania. All the changes left their mark on every aspects of life including on population health status, and all modifications were reflected in the evolution of health indicators. Considered one of the most sensitive indicators of living conditions, population health literacy level and healthcare system efficiency infant mortality rate is a negative indicator which reflects the intensity of children deaths before their first anniversary. Based on the current statistical data collected at county level, this research aims to underline the existing spatial differences in Romania at county level, to identify spatial patterns, time trend and to point out the territories that need special attention and a more profound analysis for understanding the causes that are generating them. Using mathematical and statistical methods we have calculated infant mortality for a previous and available period of time (1990 - 2010) and identified a trend influenced by exogenous and endogenous factors. With the help of GIS techniques we have created cartographic material for allowing us an easier identification of spatial disparities. Following the global trend, Romania achieved significant progress in reduction infant mortality. From values that exceeded 26 ‰ at the beginning of the nineties this indicator has continued to diminish until 9.79 ‰ in 2010. But, with all the improvements, value is still double in compare with European Union average. Although characteristic for Romania is the general downward trend, at the county level there can be identified different types of evolution and different spatial pattern. Having the lowest economic development level in the country, Northeast and Southeast counties maintain high values for infant mortality rate. Positive examples are given by Bucharest and some central and western districts, all with

    Uranium and thorium are omnipresent in our environment. Various anthropogenic activities involving the processing or use of materials rich in uranium may modify the natural abundance of uranium in water. The study is related to uranium mineralization located within Crucea ore deposit, in the East Carpathians, Romania. The Crucea uranium ore deposit is located in the eastern part of the Bistrita Mountains (40 Km southeast of the town of Vatra Dornei) in the headwaters of Crucea, Lesu and Livezi valleys. At present, this is the largest uranium mine in the country. In the past, the mining area covered 18 km2, but was gradually overtaken by logging activities. The exploration and mining facilities include thirty-two galleries, situated between 780 and 1040 m above sea level. Radioactive waste resulted from mining are disposed next to the mining facilities. The waste rock was disposed in piles of variable size that are spread over an area of 364,000 m2. Older dumps (18) have been already naturally reclaimed by forest vegetation. The vegetation cover played an important role in stabilizing the waste dump cover and in slowing down the uranium migration processes. A number of 46 water samples were taken in order to evaluate the impact of ore deposit (including its exploitation process) on the chemical composition of waters down to the exploitation galleries. The sediment samples were collected at 16 sampling points from the bottom of the studied stream waters. ICP-OES, XRF and IC methods was used to evaluate the impact of uranium mine dumps on the surface waters from Crucea region. According to the analytical data the stream waters showed a Ca - carbonate character. In relation to salinity, the pH and the anion NO3-, CO32-and SO42- contents display generally non-linear relationships with chloride. Uranium is the most significant trace element in the river waters nearby the waste rock dumps, sometimes reaching levels up to 1-mgṡL-1, well in excess of the Romanian

    In the last years the usage of solar energy has grown considerably in Romania, as well as in Europe, stimulated by various factors as government programs, green pricing policies, decreasing of photovoltaic components cost etc. Also, the rising demand of using Solar Energy Conversion Systems (SECS) is driven by the desire of individuals or companies to obtain energy from a clean renewable source. In many applications, remote consumers far from other energetic grids can use solar systems more cost-effectively than extending the grid to reach the location. Usually the solar energy is measured or forecast on horizontal surface, but in SECS there is needed the total solar radiation incident on the collector surface, that is oriented in a position that maximize the harvested energy. There are many models that convert the solar radiation from horizontal surface to a tilted surface, but they use empirical coefficients and the accuracy is influenced by different facts as geographical location or sky conditions. Such models were used considering measured values for solar radiation on horizontal plane, in the western part of Romania. Hourly values measured for global solar irradiation on the horizontal plane, diffuse solar irradiation on the horizontal plane and reflected solar irradiation by ground are used to compute the total solar radiation incident on different tilted surfaces. The calculated incident radiation is then compared with the real radiation measured on tilted surface in order to evaluate the performance of the considered conversion models.

    Up to the present, there have not been any specific norms regarding medically assisted human reproduction in Romanian legislation. Due to this situation the general legislation regarding medical assistance (law no. 95/2006, regarding the Reform in Health Care System), the Penal and Civil law and the provisions of the Code of Deontology of the Romanian College of Physicians are applied to the field of medically assisted human reproduction. By analysing the ethical and legal conflicts regarding medically assisted human reproduction in Romania, some characteristics cannot be set apart because they derive from religious, cultural and socio-economic aspects. In this article the authors identify the development stages of medically assisted human reproduction in Romania, beginning from these characteristics and insisting upon the failure of the legal system in this specific field. The authors consider that the law regarding medically assisted human reproduction cannot be effective because it did not take into account the ethical and cultural aspects that might appear. Furthermore, in this framework of the legal process, no public debate involving the representatives of civil society was undertaken although the Council of Europe Oviedo Convention approved by our country according to law no. 17/2001 stipulated exactly this working method.

    It is generally accepted that catchment sediment yield (SY, t km- 2 y- 1) can be strongly influenced by landsliding. Nevertheless, due to data requirements, only few studies investigated this effect at a regional scale. The objective of this study is therefore to explore the potential of a landslide susceptibility map for explaining the spatial variation of SY in Romania. We selected 133 catchments in Romania for which SY was measured during a period of at least 10 years. For each catchment, we derived a variety of proxies that potentially explain SY, including several indicators of landslide occurrence. The latter were derived from a published landslide susceptibility map. Results show that SY is significantly correlated with mean landslide susceptibility (r2 = 0.30). Estimates of average sheet and rill erosion rates showed a much weaker correlation with SY (r2 = 0.06). Further analyses showed that the strong correlation between SY and landslide susceptibility is mainly attributed to regional variations in lithology and seismicity. Especially the latter may play a crucial role in understanding denudation rates at regional scales, e.g. by facilitating the occurrence of landslides. Using landslide proxies that also account for sediment connectivity did not result in stronger correlations. Overall, our results show that landslide susceptibility maps can be a highly useful tool to predict SY at regional scales, provided that they incorporate all relevant factors.

    2016-01-01

    Several zoonotic tick-borne diseases are emerging in Europe due to various factors, including changes of the cultural landscape, increasing human populations, variation of social habits and climate change. We have modelled the potential range changes for two thermophilic tick species (Hyalomma marginatum and Rhipicephalus annulatus) by use of MaxEnt® and 15 climatic predictors, taking into account the aptitude for future climatic change in Romania. Current models predict increased temperatures, both in the short term (up to 2050) and in the long term (up to 2070), together with possible changes also of the other climatic factors (e.g. precipitation), and may lead to higher zoonotic risks associated with an expansion of the range of the target species. Three different models were constructed (the present, 2050 and 2070) for four representative concentration pathways (RCPs) of greenhouse gas scenarios: RCP2.6, RCP4.5, RCP6, and RCP8.5. The most dramatic scenario (RCP8.5) produced the highest increase in the probable distribution range for both species. In concordance with similar continental-wide studies, both tick species displayed a shift of distribution towards previously cooler areas of Romania. In most scenarios, this would lead to wider ranges; from 9.7 to 43.1% for H. marginatum, and from 53.4 to 205.2% for R annulatus. Although the developed models demonstrate a good predictive power, the issue of species ecology should also be considered. PMID:27245802

    The study of family structures, functioning, roles and values is fundamental in family therapist's activities for better understanding the psychological, cultural and social specificity of different clients and interventions. In this paper we describe the Romanian family and the family therapies which are available in Romania. We illustrate basic needs using demographic data and research available from Romania. The nuclear family remains dominant instead of other alternatives, the age of marriage is earlier than in western European countries and celibate and consensual living are exceptions or only for the transitional period before marriage. The role of marriage and childbirth within the marital setting is still important. The model of a single child appears increasingly common due to an improvement in financial resources and better living conditions. Relations with family of origin remain close. The difficulties for children with parents working in different countries raise problems and have implications for the extended family, educators and psychotherapists as well as mental health service providers. Family therapists should keep in mind the structure, function, role and values of the Romanian family for better understanding the issues and resources and use these accordingly in therapy. Policy-makers should be aware of the difficulties concerning availability and access to this therapeutic approach.

    We describe a rubella outbreak that occurred in Romania between September 2011 and December 2012. During this period 24,627 rubella cases, 41.1% (n=10,134) of which female, were notified based on clinical criteria, and a total of 6,182 individuals were found serologically positive for IgM-specific rubella antibody. The median age of notified cases was 18 years (range: <1-65) and the most affected age group 15 to 19 years (n=16,245 cases). Of all notified cases, 24,067 cases (97.7%) reported no history of vaccination. Phylogenetic analysis of 19 sequences (739 nucleotides each), from 10 districts of the country revealed that the outbreak was caused by two distinct rubella virus strains of genotype 2B, which co-circulated with both temporal and geographical overlap. In addition to the 6,182 IgM-positive rubella cases, 28 cases of congenital rubella syndrome (CRS) were identified, including 11 neonatal deaths and one stillbirth. The outbreak underscores the need to encourage higher vaccination uptake in the population, particularly in women of reproductive age, and to strengthen epidemiological and laboratory investigations of suspected rubella cases. Genetic characterisation of wild-type rubella virus is an essential component to enhance surveillance and here we report rubella virus sequences from Romania. PMID:27684329

    Romania has the highest cervical cancer burden in Europe. Despite the implementation of two human papillomavirus (HPV) vaccination programmes, the uptake remained extremely low and the programmes were discontinued. Given that media are a common source of information for the public and may influence vaccination decisions, this article sought to explore the content and quality of HPV vaccine media coverage in Romania. We conducted a content analysis of 271 media reports (from newspapers, magazines, videos and informational websites) published online between November 2007 and January 2012. Overall, results indicated that 31.4% of the materials were neutral, 28% were negative or extremely negative, 17% were mixed, while 23.6% were positive towards the vaccine. The most dominant vaccine-related concerns were side effects and insufficient testing. Elementary information about the vaccine and HPV was constantly left out and sometimes inaccuracies were found. Negatively disposed reports were more likely to contain incorrect data about vaccine efficacy and less likely to provide comprehensive information about the vaccine and HPV-related diseases. Some dimensions of media coverage varied across time and media outlets. The present findings suggest that educational interventions are greatly needed as a response to suboptimal and incomplete media coverage of HPV vaccination. PMID:24890190

    Early human footprints are rare in the fossil record. A survey of the literature reveals very few well documented and dated cases. Here, we report the first clear Homo neanderthalensis footprint. It was found in Vârtop Cave, Romania. The individual stepped into calcareous mud that later hardened. The 22 cm long print suggests a body height of ˜1.46 m; a gap of 1.6 cm marks the separation of big and second toes. The date of the footprint is constrained by three coeval dates of ˜62 kyr on sub-samples from the basal layer of a nearby stalagmite that grew on top of the layer of calc-tufa covering the footprint. The lower constraint is a poorly constrained uranium (U)-thorium (Th) isochron date of ˜97 kyr on the calc-tufa layer in which the footprint is embedded. Thus, the Vârtop Cave individual lived in Romania sometime before 62 kyr, long before the appearance of Homo sapiens in Central and Eastern Europe, the earliest records of which date from only ˜35 kyr. To our knowledge, this is the first recognised and dated Homo neanderthalensis footprint.

    To investigate the transmission of species of Cryptosporidium Tyzzer, 1907 in Timis County, Romania, 48 isolates of Cryptosporidium coccidia from 11 children, 29 calves and eight pigs were characterised by molecular analysis of two loci (SSU rRNA and 60-kDa glycoprotein gene). Overall, 22 isolates were amplified and sequence analyses revealed that all isolates were Cryptosporidium parvum Tyzzer, 1912. Two subtype families were identified, IIa and IId. Subtype IIdA22G1 (n = 4) was the single C. parvum subtype found in children. Subtypes found in calves included IIdA27G1 (n = 8), a novel subtype, IIdA25G1 (n = 5), IIdA22G1 (n = 2), IIdA21G1a (n = 1), and IIaA16G1R1 (n = 1). Subtype IIdA26G1 was found in a pig. These results were significantly different from previous Romanian reports, as the five subtypes of family IId identified in this study were never identified previously in this country. Thus, cattle may be a source of Cryptosporidium infections for humans and the transmission dynamics of C. parvum in Romania is more complex than previously believed.

    Fungal contamination of plant products is an important risk factor for health, because of the high mycotoxin potential deriving from these contaminations with multiple effects: hepatic toxicity, teratogenic, mutagenic and carcinogenic. The contamination of cereals with mycotoxins has been a serious problem in Balkan communities. Several studies implicated mycotoxins, in endemic kidney disease geographically limited to Balkan region (Balkan endemic nephropathy). The trichothecenes are of particular concern because they are ubiquitous found in wheat, corn and barley throughout the world. Fumonisins have been isolated from certain Fusarium species of which FB1, FB2 and FB3 are the major ones produced in naturally contaminated foods.These mycotoxins are produced on cereal grains infected by Fusarium while being grown in-the-field. The aim of this study is to evaluate the presence of the Fusarium species in cereals from West side of Romania and to determinate the concentrations of deoxynivalenol (DON) and fumonisine (F1+F2). Identification of Fusarium species was done using the total number of fungal species determination method. The level of mycotoxins was determined with the immune-enzymatic method ELISA. 27 cereal samples from rural households in three counties in West Romania were analysed.

    Islands are noted for the occurrence of aberrant, endemic, and dwarfed taxa (the “island effect”). Late Cretaceous vertebrate assemblages of Romania and elsewhere in Europe are classic examples of island faunas in the fossil record, and are characterized by dwarfed herbivorous dinosaurs and other endemic taxa that are noticeably primitive relative to their mainland contemporaries. Fossils of the predators inhabiting the European paleoislands, however, are exceptionally rare and fragmentary. We describe a new dromaeosaurid theropod, based on an articulated skeleton from the Maastrichtian of Romania, which represents the most complete predatory dinosaur from the middle to Late Cretaceous of Europe. This taxon is characterized by a peculiar body plan, most notably extensive fusion in the hand and distal hindlimb, a highly retroverted pelvis with enlarged femoral muscle attachments, and a pair of hyperextensive pedal claws. However, unlike the island-dwelling herbivorous dinosaurs, its closest relatives are contemporary similar-sized Laurasian taxa, indicating faunal connections between Asia and the European islands late into the Cretaceous. This theropod provides support for the aberrant nature of the Late Cretaceous European island-dwelling dinosaurs, but indicates that predators on these islands were not necessarily small, geographically endemic, or primitive.

    Blood samples of 119 red foxes, originating from 44 hunting grounds of 3 western counties (Arad, Hunedoara, and Timiş) of Romania, have been examined for the presence of Hepatozoon canis infection using the conventional polymerase chain reaction (PCR) of the fragment of 18S rRNA gene. Overall, 15 (12.6%) samples were found to be PCR-positive. Of the sampled hunting grounds, 29.5% (13/44) were found positive. Positive samples were recorded in all screened counties with the prevalence of 14.8% (9/61) in Arad, 9.8% (5/51) in Timiş, and 14.3% (1/7) in Hunedoara, respectively. No correlation was found (P > 0.05) between H. canis positivity and gender or territorial distribution of the infection. To confirm PCR results, 9 randomly selected amplicons were sequenced. The obtained sequences were identical to each other, confirmed the results of the conventional PCR, and showed 98-100% homology to other H. canis sequences. The results of the current survey support the role of red foxes as sylvatic reservoirs of H. canis in Romania.

  15. Mass media coverage of HPV vaccination in Romania: a content analysis.

    2014-12-01

    Romania has the highest cervical cancer burden in Europe. Despite the implementation of two human papillomavirus (HPV) vaccination programmes, the uptake remained extremely low and the programmes were discontinued. Given that media are a common source of information for the public and may influence vaccination decisions, this article sought to explore the content and quality of HPV vaccine media coverage in Romania. We conducted a content analysis of 271 media reports (from newspapers, magazines, videos and informational websites) published online between November 2007 and January 2012. Overall, results indicated that 31.4% of the materials were neutral, 28% were negative or extremely negative, 17% were mixed, while 23.6% were positive towards the vaccine. The most dominant vaccine-related concerns were side effects and insufficient testing. Elementary information about the vaccine and HPV was constantly left out and sometimes inaccuracies were found. Negatively disposed reports were more likely to contain incorrect data about vaccine efficacy and less likely to provide comprehensive information about the vaccine and HPV-related diseases. Some dimensions of media coverage varied across time and media outlets. The present findings suggest that educational interventions are greatly needed as a response to suboptimal and incomplete media coverage of HPV vaccination.

    Blood samples from 49 symptomatic dogs from 5 western and north-western counties of Romania were screened using microscopic examination, polymerase-chain-reaction-restriction-fragment-length-polymorphism procedure (PCR-RFLP), and sequence analysis. Results of the microscopic evaluation of stained blood smears revealed 45 positive samples with the presence of large and small intraerythrocytic piroplasms in 35 and 10 samples, respectively. Babesia canis (35/49, 71.4%) and Babesia gibsoni (14/49, 28.6%) were identified and differentiated by PCR-RFLP targeting the 18S rRNA gene. Results of the sequence analysis of all B. gibsoni and 17 randomly selected B. canis PCR products confirmed the PCR-RFLP-diagnosed species. The distribution of B. gibsoni infection was positively associated (p<0.001) with fighting dog breeds including infection in 12 American Pit Bull Terriers and one American Staffordshire Terrier. This report is the first to present molecular evidence of the occurrence of B. gibsoni in Romania confirmed by sequencing.

    The environmental impact assessment of mining sites represents nowadays a large interest topic in Romania. Historical pollution in the Rosia Montana mining area of Romania caused extensive damage to environmental media. This paper has two goals: to investigate the environmental pollution induced by mining activities in the Rosia Montana area and to quantify the environmental impacts and associated risks by means of an integrated approach. Thus, a new method was developed and applied for quantifying the impact of mining activities, taking account of the quality of environmental media in the mining area, and used as case study in the present paper. The associated risks are a function of the environmental impacts and the probability of their occurrence. The results show that the environmental impacts and quantified risks, based on quality indicators to characterize the environmental quality, are of a higher order, and thus measures for pollution remediation and control need to be considered in the investigated area. The conclusion drawn is that an integrated approach for the assessment of environmental impact and associated risks is a valuable and more objective method, and is an important tool that can be applied in the decision-making process for national authorities in the prioritization of emergency action.

  3. Constructing interethnic conflict and cooperation: why some people harmed Jews and others helped them during the Holocaust in Romania.

    PubMed

    Dumitru, Diana; Johnson, Carter

    2011-01-01

    The authors draw on a natural experiment to demonstrate that states can reconstruct conflictual interethnic relationships into cooperative relationships in relatively short periods of time. The article examines differences in how the gentile population in each of two neighboring territories in Romania treated its Jewish population during the Holocaust. These territories had been part of tsarist Russia and subject to state-sponsored anti-Semitism until 1917. During the interwar period one territory became part of Romania, which continued anti-Semitic policies, and the other became part of the Soviet Union, which pursued an inclusive nationality policy, fighting against inherited anti-Semitism and working to integrate its Jews. Both territories were then reunited under Romanian administration during World War II, when Romania began to destroy its Jewish population. The authors demonstrate that, despite a uniform Romanian state presence during the Holocaust that encouraged gentiles to victimize Jews, the civilian population in the area that had been part of the Soviet Union was less likely to harm and more likely to aid Jews as compared with the region that had been part of Romania. Their evidence suggests that the state construction of interethnic relationships can become internalized by civilians and outlive the life of the state itself.

    Halicephalobus gingivalis (H. gingivalis) causes a rare and fatal infection in horses and humans. Despite the zoonotic potential and severity of the disease, the epidemiology and pathogenesis of halicephalobiasis are still poorly understood. Several European cases of equine halicephalobiasis have been documented; however, in South-Eastern European countries, including Romania, equine neurohelminthiasis caused by H. gingivalis has not been previously described. Two Lipizzaner horses with a clinical history of progressive neurological signs were referred to the Pathology Department of the Cluj-Napoca (Romania) for necropsy. Both horses died with severe neurological signs. Gross examination and cytological, histological, and molecular analyses were performed. The stallions came from two different breeding farms. No history of traveling outside Romania was recorded. At necropsy, granulomatous and necrotizing lesions were observed in the kidneys, lymph nodes, brain, retroperitoneal adipose tissue, and lungs, indicating a systemic infection. Parasitological and histopathological analyses evidenced larval and adult forms of rhabditiform nematodes consistent with Halicephalobus species. Parasites were observed in both lymph and blood vessels of different organs and were also identified in urine samples. A subunit of the large-subunit ribosomal RNA gene (LSU rDNA) of H. gingivalis (673 bp) was amplified from lesions in both horses.To the authors' knowledge, this is the first report of equine systemic H. gingivalis infection in Romania and in South-Eastern Europe. Our findings provide new insights into the geographic distribution of specific genetic lineages of H. gingivalis, while also raising public health awareness, as the parasite is zoonotic.

    The 14-MW TRIGA steady state reactor (SSR) is located in Pitesti, Romania. Beginning with an HEU core (10 wt% U), the reactor first went critical in November 1979 but was shut down ten years later because of insufficient excess reactivity. Last November the Institute for Nuclear Research (INR), which operates the SSR, received from the ANL RERTR program a shipment of 125 LEU pins fabricated by General Atomics and of the same geometry as the original fuel but with an enrichment of 19.7% 235U and a loading of 45 wt% U. Using 100 of these pins, four LEU clusters, each containing a 5 x 5 square array of fuel rods, were assembled. These four LEU clusters replaced the four most highly burned HEU elements in the SSR. The reactor resumed operations last February with a 35-element mixed HEU/LEU core configuration. In preparation for full power operation of the SSR with this mixed HEU/LEU core, a number of measurements were made. These included control rod calibrations, excess reactivity determinations, worths of experiment facilities, reaction rate distributions, and themocouple measurements of fuel temperatures as a function of reactor power. This paper deals with a comparison of some of these measured reactor parameters with corresponding analytical calculations.

    In recent years, the ecological environment of plain rivers within Haihe River basin is questionable because of severe water shortages. Most of the rivers dry up regularly and it is therefore necessary to take measures to improve the river ecological environment. Meanwhile, flood control is the principal function for most of the dried-up rivers, so river regulation works for flood control also should be undertaken. In this paper, some measures of river regulation were selected applied to the Haihe River basin, taking these measures not only ensure the river security but also realize its ecological benefit. Examples of the application of selected measures for the representative rivers, Yongding River and Hutuo River, both located within the Haihe River basin, are also assessed. These measures provide practical solutions to ecological and flood control problems of dried-up rivers, are generic in nature, and could therefore be applied to other same type rivers.

    INTRODUCTION Wide-spread environmental contamination associated with historic mining in Europe has triggered social responses to improve related environmental legislation, the environmental assessment and management methods for the mining industry. Pollution by acid mine drainage (AMD) from ore and coal mining is the outstanding and most important source of mining-induced environmental pollution. Younger et al. (2002) estimates that watercourses polluted by coal mine drainage could be in the order of 2,000 to 3,000 km, and 1,000 to 1,500 km polluted by metal mine discharges for the EU 15 Member States (Younger et al. 2002). Significance of contamination risk posed by mining is also highlighted by mine accidents such as those in Baia Mare, Romania in 2002 and in Aznalcollar, Spain in 1999 (Jordan and D'Alessandro 2004). The new EU Mine Waste Directive (Directive 2006/21/EC) requires the risk-based inventory of abandoned mines in the EU. The cost-effective implementation of the inventory is especially demanding in countries with extensive historic mining and great number of abandoned mine sites, like Romania. The problem is further complicated in areas with trans-boundary effects. The objective of this investigation to carry out the risk-based contamination assessment of a mine site with possible trans-boundary effects in Romania. Assessment follows the source-pathway-receptor chain with a special attention to heavy metal leaching from waste dumps as sources and to transport modelling along surface water pathways. STUDY AREA In this paper the Baiut mine catchment located in the Gutai Mts., Romania, close to the Hungarian border is studied. The polymetallic deposites in the Tertiary Inner-Carpathian Volcanic Arc are exposed by a series of abandoned Zn and Pb mines first operated in the 14th century. Elevation in the high relief catchment ranges from 449m to 1044m. Geology is characterised by andesites hosting the ore deposits and paleogene sediments dominating at the

    2016-01-01

    Abstract The Romanian Protura were studied based on 175 specimens collected from Romania, along with bibliographic data. The main publication on the Romanian proturans was written by M.A. Ionescu (1951), who described 13 species mainly from soil and forest litter from 15 collecting points. The current paper represents the first study at a national level. Faunal data on Protura were obtained from 22 sites, mostly from forests of the Romanian Carpathians and also from a peri-urban area of Bucharest, which had not been studied before. As a result, the Romanian Protura fauna now consists of 27 known taxa in 6 genera and 4 families. Of the 27 taxa, 15 species are new records for Romanian fauna. An identification key to the Romanian Protura species is provided. PMID:26865814

  1. Payment systems and incentives in primary care: implications of recent reforms in Estonia and Romania.

    2015-01-01

    Since the early 1990s, major reform in healthcare has been adopted in former communist countries in Central and Eastern Europe. More than 20 years after, reform in healthcare still draws much interest from policy makers and academics alike. One of the dynamic components of reform has been the reform of payment systems in primary care. This article looks at recent developments in payment systems and financial incentives in Estonia and Romania. We conclude that finding the appropriate mix in paying and incentivizing primary care providers in a transitional context is no easy solution for healthcare policy makers who need to carefully weigh in the advantages and inherent problems of various payment arrangements. In a transitional, rapidly changing healthcare system and society, and a context of financial stringency, the theoretical effects of payment mechanisms may be more difficult to predict and manage than it is expected.

    This article discusses the relationship between race and physical anthropology in Hungary and Romania between 1900 and 1940. It begins by looking at institutional developments in both countries and how these influenced the most important Hungarian and Romanian anthropologists' professional and research agendas. Drawing from a wide range of primary sources, the article reveals the significant role the concept of race played in articulating anthropological and ethnic narratives of national belonging. It is necessary to understand the appeal of the idea of race in this context. With idealized images of national communities and racial hierarchies creeping back into Eastern European popular culture and politics, one needs to understand the latent and often unrecognized legacies of race in shaping not only scientific disciplines like anthropology, but also the emergence and entrancement of modern Hungarian and Romanian nationalism.

    A new giant pterosaur, Hatzegopteryx thambema, nov.gen., nov.sp., from the Maastrichtian Densuş-Ciula Formation of Romania is remarkable for its very large size (estimated wing span > or = 12 m) and for the robustness of its large skull, which may have been nearly 3 m long. The stout skull bones contrast with the usually thin and slender skull elements of other pterosaurs, and raise the question of how the weight of the skull was reduced in order to make flight possible. The answer probably lies in the very peculiar internal structure of the bones, which consists of a dense network of very thin trabeculae enclosing small alveoli. This structure is reminiscent of expanded polystyrene and, like it, probably combined strength with lightness.

    Although international research is increasing in volume and importance, there remains a dearth of knowledge on similarities and differences in “national human research ethics” (NHREs), that is, national ethical guidelines (NEGs), Institutional Review Boards (IRBs), and research stakeholder’ ethical attitudes and behaviors (EABs). We begin to address this situation by reporting upon our experiences in conducting a multinational study into the mental health of children who had a parent/carer in prison. The study was conducted in 4 countries: Germany, Great Britain, Romania, and Sweden. Data on NHREs were gathered via a questionnaire survey, two ethics-related seminars, and ongoing contact between members of the research consortium. There was correspondence but even more so divergence between countries in the availability of NEGs and IRBs and in researcher’ EABs. Differences in NHREs have implications particularly in terms of harmonization but also for ethical philosophy and practice and for research integrity. PMID:27746664

    The prevalence of Toxoplasma gondii, an economically important zoonotic protozoan, was investigated in horses slaughtered for export and human consumption in the North of Romania. Pairs of samples, sera and heart tissues, were collected from 82 slaughtered horses. Examination of horse sera by ELISA at a dilution of 1:10, and by modified agglutination test (MAT) at a dilution of 1:6, revealed that 32 (39%) and 31(37.8%) horses, respectively, had antibodies against T. gondii. Using polymerase chain reaction (PCR) analysis, T. gondii DNA was not found in any heart sample collected from horses. By bioassay in mice, we obtained viable isolates of T. gondii from two of ten horses determined to be strongly positive by serological assay/ELISA. The prevalence estimated in horses highlighted the potential risk for human contamination by consumption of raw or undercooked meat.

    A complete inventory of the 631 glacial cirques in Romania (and adjacent Ukraine) shows that they are scale-specific and develop allometrically, extending in length more rapidly than they deepen: shape changes with size. Horizontal dimensions are around 700 m, vertical around 300 m. On each quantitative measure they form a single, unimodal population with limited variation in size (on a logarithmic scale). Cirque axial gradients (15-33°) are appropriate to occupation by rotationally-flowing glaciers. Lake basins are more common (26%) on granitic rocks, compared with 10.6% of all cirques. Geology also affects vertical dimensions and gradients. The relation between subjective (five grades) and objective measures of cirque development is shown by an r2 of 62% when Grade is predicted from maximum gradient, minimum gradient, and plan closure. Cirques larger in horizontal dimensions have better grades.

    Evidence from politically and socially stable countries in Northern Europe and the Southern Hemisphere indicates a marked decrease in the seasonality of suicide over the past two decades. Generalizabiity of this trend to societies in transition has not yet been investigated. Data for suicide by hanging in Timiş County of Romania show both a nondecrease in seasonality of suicide for the current transitional period (1990-98), relative to the last decade of the Communist regime (1980-89) and shifts in location for suicide peak and trough months. Recent decreases in the seasonality of suicide might not generalize to societies in transition, and research would improve from focusing on the "natural laboratories" these societies represent.

    The Romanian Protura were studied based on 175 specimens collected from Romania, along with bibliographic data. The main publication on the Romanian proturans was written by M.A. Ionescu (1951), who described 13 species mainly from soil and forest litter from 15 collecting points. The current paper represents the first study at a national level. Faunal data on Protura were obtained from 22 sites, mostly from forests of the Romanian Carpathians and also from a peri-urban area of Bucharest, which had not been studied before. As a result, the Romanian Protura fauna now consists of 27 known taxa in 6 genera and 4 families. Of the 27 taxa, 15 species are new records for Romanian fauna. An identification key to the Romanian Protura species is provided.

    The incidence of whooping cough in Romania is substantially underestimated, and, as noted by the health authorities, this is mostly due to the lack of both awareness and biological diagnosis. We conducted a 1-year study in Bucharest in order to assess the circulation of Bordetella pertussis, the main etiological agent of whooping cough. Fifty-one subjects suspected of whooping cough were enrolled. Culture, real-time PCR, and enzyme-linked immunosorbent assay were used for laboratory diagnosis. Whooping cough patients (63%) were distributed among all age groups, and most were unvaccinated, incompletely vaccinated, or had been vaccinated more than 5 years previously. Bordetella holmesii DNA was detected in 22% of the bordetellosis cases; these patients included adults; teenagers; and, surprisingly, young children. B. pertussis isolates were similar to the clinical isolates currently circulating elsewhere in Europe. One isolate does not express pertactin, an antigen included in some acellular pertussis vaccines.

    This article discusses the relationship between race and physical anthropology in Hungary and Romania between 1900 and 1940. It begins by looking at institutional developments in both countries and how these influenced the most important Hungarian and Romanian anthropologists' professional and research agendas. Drawing from a wide range of primary sources, the article reveals the significant role the concept of race played in articulating anthropological and ethnic narratives of national belonging. It is necessary to understand the appeal of the idea of race in this context. With idealized images of national communities and racial hierarchies creeping back into Eastern European popular culture and politics, one needs to understand the latent and often unrecognized legacies of race in shaping not only scientific disciplines like anthropology, but also the emergence and entrancement of modern Hungarian and Romanian nationalism.

    The FLUKA 2011.2c code was used to evaluate the activity induced in the irradiation chamber walls by secondary charged particles emitted during the interaction of 1 petawatt laser beam with the targets. The results have shown that, even in the most conservative approaches, i.e. 300 and 100 MeV secondary electrons and protons, respectively, the maximum equivalent dose rate, at 1 cm in front of the chamber wall, 1 min after the end of irradiation, was of ∼23 nSv h(-1). Three minutes later, it falls at ∼60 pSv h(-1), negligible with respect to the environmental radiation background of 90-110 nSv h(-1), as reported for Romania.

    This paper is focused on airborne measurements of microphysical parameters into warm clouds when the aircraft penetrates the cloud, both during take-off and landing. The experiment was conducted during the aircraft flight between Bucharest and Craiova, in the southern part of Romania. The duration of the experimental flight was 2 hours and 35 minutes in October 7th, 2014, but the present study is dealing solely with the analysis of cloud microphysical properties at the beginning of the experiment (during the aircraft take-off) and at the end, when it got finalized by the aircraft landing procedure. The processing and interpretation of the measurements showed the differences between microphysical parameters, emphasizing that the type of cloud over Bucharest changed, as it was expected. In addition, the results showed that it is important to take into account both the synoptic context and the cloud perturbation due to the velocity of the aircraft, in such cases.

    This observational study focused on three-years time-averaged data set (January 2012-2015). An investigation of long-term trends was performed on two different data sets derived from active and passive remote sensing measurements in Magurele, Romania. Measurements of sun photometer aerosol optical depth (AOD) at 500 nm and 340 nm show the mean values of 0.230 ±0 .118 and 0.398 ± 0.185, respectively. The lidar AOD at 532 and 355nm has a mean of 0.271 ±.0.164 and 0.472 ± 0.165 respectively. The highest seasonal mean value was measured by the lidar during the summer of 2014 while the lowest seasonal value was measured by the sunphotometer in February 2012. The origin of atmospheric aerosols has been analyzed using both backtajectories of Hysplit and Circulation Type Classification (CTCs) methods.

    SUMMARY Objectives The objective of this paper is to provide information on indoor air quality and on the quality of the broader indoor environment of the houses in Roma villages in Slovakia and Romania and to discuss possible implications for health. Methods Indoor air was sampled in 11 houses in a Romanian Roma village and in 19 houses in a Slovakian Roma village. Levels of Carbon Monoxide (CO), Carbon Dioxide (CO2), total particulate matter (PM), temperature and humidity were measured. A questionnaire and a checklist were used to obtain additional information on the indoor environment and behavioural factors. We have sampled the same houses in winter and in summer. Results Levels of CO and CO2 were higher in winter in both countries as compared to summer. The limit value of 10 mg/m3 CO was exceeded in a few cases in both countries. In general, levels of CO, CO2 and PM were higher in Romania. Further environmental and behavioural hazards such as indoor smoking, pets inside or lack of ventilation were found. The reported self-perceived quality of the indoor environment was poor in many aspects. Conclusions Our findings of CO, CO2 and PM levels suggest that indoor air pollution in Roma settlements has the potential to be a health threat. The fact that the inhabitants spend a relatively long time inside the houses and that a number of additional environmental and behavioural hazards were identified by our study emphasizes the importance of the indoor air quality for health and thus priority attention should be paid to these issues by health authorities and researchers. Further research is essential and study designs must consider cultural background and specific characteristics of the community, especially in order to obtain valid data on health outcomes.

    Although not endemic in the European Union and European Economic Area, shigellosis is included among the priority food- and waterborne diseases carefully surveyed by the European Centre for Disease Prevention and Control. From 2010 to 2012, 1018 cumulated confirmed shigellosis cases were reported to the European Surveillance System by Romania. This retrospective study aimed to provide insights into the antibiotic resistance and genetic diversity of a set of Shigella sonnei isolates recovered during that period. A total of 59 S. sonnei isolates were subjected to antimicrobial susceptibility testing (ampicillin, cefotaxim, chloramphenicol, streptomycin, gentamicin, kanamycin, tetracycline, sulphonamides compound, trimethoprim, trimethoprim-sulfamethoxazole, nalidixic acid, and ciprofloxacin), biotyping, and molecular characterization of resistance to third-generation cephalosporins, fluoroquinolones, and integron content. Pulsed-field gel electrophoresis (PFGE) was performed in order to assess the genetic relatedness of the isolates. Thirty-eight (64%) of the studied isolates displayed multidrug-resistant (MDR) phenotypes, the most common resistance profile comprising resistance to ampicillin, streptomycin, sulphonamides compound, trimethoprim, and trimethoprim-sulfamethoxazole. Resistance to cefotaxim was detected in a biotype g blaCTX-M-15 and a biotype e blaCMY-2-positive isolate, respectively. Resistance to ciprofloxacin and/or nalidixic acid was detected in three MDR isolates and was due to known mutations in gyrA gene leading to aminoacid substitutions (i.e. Ser83Leu, Asp87Tyr, Asp87Gly). Either class 1 or class 2 integrons were identified in 10 isolates. Comparisons of XbaI PFGE patterns of S. sonnei isolates revealed 9 clonal groups and 6 unique patterns. The genotyping results suggested that dissemination of clonal groups of S. sonnei may have persisted over the years in Romania. PMID:26727851

    A comprehensive radon survey has been carried out in Băiţa radon-prone area, Transylvania, Romania, in 4 localities (Băiţa, Nucet, Fînaţe, and Cîmpani) situated in the vicinity of former Romanian uranium mines. Indoor radon concentrations have been measured in 1128 ground floor rooms and cellars of 303 family houses by using CR-39 diffusion type radon detectors. The annual average of indoor radon concentration for Băiţa area was found to be 241±178 Bq m(-3), which is about two times higher than the average value of 126 Bq m(-3), computed for Romania. About 28% of investigated houses exceed the reference level of radon gas in dwellings of 300 Bq m(-3). The indoor radon measurements on each house have been carried out in several rooms simultaneously with the aim of obtaining a more detailed picture on the exposure to radon in the studied area. An analysis on the variability of radon levels among floors (floor-to-floor variation) and rooms (room-to-room variation) and also the influence of factors like the presence of cellar or the age of the building is presented. The coefficient of variation (CV) within ground floor rooms of the same house (room-to-room variation) ranged between 0.9 and 120.8%, with an arithmetic mean of 46.2%, a large variability among rooms within surveyed dwellings being clearly identified. The mean radon concentration in bedrooms without cellar was higher than in bedrooms above the cellar, the difference being statistically significant (t test, one tail, p<0.001, n=82). For houses built during 1960-1970 an increasing trend for radon levels was observed, but overall there was no significant difference in indoor radon concentrations by age of dwelling (one-way ANOVA test, p>0.05).

    Landslides are a common feature in the landscape of the Romanian hills and plateaus, affecting around 7% of the national territory (Pusch, 2004). It is general knowledge that landslides represent the combined result of a series of predisposing factors (lithology, faults, slope, land-use, land cover, etc.) with long term impact on slope stability and triggering factors (rainfall, snow melt, earthquakes) that temporarily modify the local hydrogeological conditions (Corominas, 2008). Rainfall represents the most common triggering factor of landslides in the Ialomita Subcarpathians, therefore the determination of rainfall thresholds for landslides initiation would be very useful for landslide hazard assessment and implementation of warning systems. This paper aims to determine regional rainfall thresholds in the Subcarpathian area between the Prahova and Ialomita Valleys, where the most frequent phenomena are: deep seated rotational slides, earth flows and complex movements (rotational slides combined with mudflow or translational slides). The methodology used in studies addressing the regional scale is based on empirical or statistical analysis of rainfall, due to the spatial and temporal variation of landslide factors. Given the lack of hourly measurements of rainfall variables for long periods in Romania we were constrained to determine the corresponding rainfall thresholds based on cumulated precipitation during the landslide events. The rainfall variables were chosen based on the typology of landslides: daily rainfall in the case of shallow landslides usually triggered by short and intense rainfall, normalized total precipitation (antecedent and event rainfall) for deep-seated landslides. After establishing what thresholds correspond to the different types of landslides, we continued by analyzing the spatial and temporal variability of the pluvial regime aiming to understand the over time occurrence of landslides in the Subcarpathian area between the Prahova and

    Drought is a phenomenon that appears due to precipitation deficit and it is intensified by strong winds, high temperatures, low relative humidity and high insolation; in fact, all these factors lead to increasing of evapotranspiration processes that contribute to soil water deficit. The Standardized Precipitation Evapotranspiration Index (SPEI) take into account all this factors listed above. The temporal variability of the drought in Eastern part of Romania for 50 years, during the period 1961-2010, is investigated. This study is focused on the drought variability related to large scale air circulation. The gridded dataset with spatial resolution of 0.5º lat/lon of SPEI, (https://digital.csic.es/handle/10261/72264) were used to analyze drought periods in connection with large scale air circulation determinate from the two catalogues (GWT - GrossWetter-Typen and WLK - WetterLargenKlassifikation) defined in COST733Action. The GWT catalogue uses at input dataset the sea level pressure and the WLK catalogue uses as input dataset the geopotential field at 925 hPa and 500 hPa, wind at 700 hPa and total water content for entire atmospheric column. In this study we use the GWT catalogue with 18 circulation types and the WLK catalogue with 40 circulation types. The analysis for Barlad Hydrological Basin indicated that the negative values (that means water deficit - drought period) of SPEI are associated with prevailing anticyclonic regime and positive values (that means water excess - rainy period) of SPEI are associated with prevailing cyclonic regime as was expected. In last decade was observed an increase of dry period associated with an increase of anticyclonic activity over Romania. Using GWT18 catalogue the drought are associated with the north-eastern anticyclonic circulation type (NE-A). According to the WLK40 catalogue, the dominant circulation type associated with the drought is north-west-anticyclonic-dry anticyclonic (NW-AAD) type. keywords: drought, SPEI

    Robust signs of climate change, especially in temperature-related climate behaviour, are already present. Heatwave frequency, intensity and persitance are changing under climate change conditions and so are the exposure to them and associated risks. Urban areas have additional thermal-related vulnerabilities due to effects of urban heat island on large populations concentrated in a human-transformed space. The goal of our study is to use climate and socio-economic data to assess changes in heatwave risks for the urban area of Arad municipality in Romania. Arad municipality is in the top ten towns in Romania with largest contribution to gross domestic product (GDP), covering of 253 km2 and with a population of 169327. Arad is representative for towns situated over plane areas and the results of our study can be translated for other Romanian towns as well. For our purpose we used remote sense and climate data with health, demography and land use information to develop a climate change risk assessment for heatwaves. We used skin temperature from Modis products (2000-2010), air temperature from Arad weather station (1961-2010), Corine land cover and demographic information from 2004 census. Results from regional climate models obtained from FP6 ENSEMBLES project are used for future projection of air temperature in 21st century. Our analysis builds on the EU Council conclusions on "Further Developing Risk Assessment for Disaster Management within the European Union" adopted in March 2011 that aims for a common approach and harmonisation on the prevention of natural and man-made disasters setting out an overall disaster prevention framework.

    Two heavy precipitation events that affected the north-eastern part of Romania are here described in terms of meteorological analysis. Synoptic and mesoscale conditions associated with these events are representative of a class of phenomena that produce important effects on the urban and extra-urban areas from this part of the country as a consequence of floods and flash floods. Analyses of these regional meteorological processes that generate flash floods are one of the objectives of the HYDRATE project. Romanian territory is affected by the presence of the Mediterranean Lows that transport moist and warm air from Mediterranean Sea basin. In certain meteorological conditions the Mediterranean Lows moving to East of Europe, get a retrograde movement on the Black Sea and in this way they contribute to the moisture increasing content of the forming convective systems. The retrograded Mediterranean Lows affect primary the north-eastern part of the Romania. Additionally, different mesoscale forcing mechanisms acts to continuously generate convective cells and focus the deep convection over the same region during several hours incrising in this way the flash flood potential. Heavy precipitation events selected for analyses occurred, first of it, on 18-19 August 2005, and the second on the 23-26 July 2008, and resulted in floods and flash floods conducive to human fatalities and important economic and social damages. ECMWF model analysis was used to investigate dynamical forcing and mesoscale numerical simulation using ALADIN model was performed to investigate the mechanism responsible for the convection development. Data from conventional weather station, radar and satellite imagery were used to assess the magnitude of the rain events and to investigate the role of the different mode of convective system organization to the flash floods generation.

  3. Changes in the forest ecosystems in areas impacted by aridization in south-western Romania

    2014-01-01

    Background In the past few decades, global climate change has accentuated the intensification of aridization in South-Western Romania, with direct and indirect consequences on the quality of forest ecosystems. In addition to qualitative deterioration, the quantitative changes brought about by intensive anthropic deforestation have created the conditions for a decline in the size of forest areas on vast tracts of land. The paper aims to analyze the qualitative and quantitative changes in the forest ecosystems in South-Western Romania, changes due to the synergic context of the global climate changes and the anthropic pressures of the past three decades. In order to capture the evolution of aridization in the study area, specific aridization indexes have been calculated, such as the De Martonne index and the UNEP aridity index. 1990 and 2011 satellite images have been used in order to quantify the qualitative changes. Results The results obtained indicated that, in the past two decades, the quality of the biomass declined as a result of the increase in the climatic aridity conditions (De Martonne si UNEP aridity index, indicating in the last decades, annual values under 15 mm/°C, and under 0.5 mm/mm, that means that the values situated under these thresholds, describe arid and semi-arid climate conditions). Also, the uncontrolled logging across vast surfaces caused the loss of forest ecosystems by 7% in the overall study area, during the last three decades. Conclusions The severe effects of aridization meant, first of all, a significant decline in the quality of the ecosystem services supplied by forests. In the absence of viable actions to correct the present situation, the extremely undesirable consequences of an ecological and social nature will arise in the near future. PMID:24393389

    Sorghum holepense is an extremely wide spread species, being met in many European, Asian, American and African countries and covering approximately 1/3 of the land cultivated with fields crops, grapevine, fruit trees and vegetables. In Romania, Sorghum halepense is present in almost all the country, invading in hoed-plants ad vegetable crops as well as grapevine and fruit-tree plantations. The losses caused by Sorghum halepense are enormous; in case of maize and sugar beet crops, these losses reach and extremely high rate of 30-70%. For these reasons, at the University of Agricultural Sciences and Veterinary Medicine, Timisoara, city in western part of Romania, a study was made having as objects the latest herbicides synthesized in the world: Equip--which contains 22.5 g/l foramsulfuron + 22.5 g/l isoxadifen-ethyl (safener); Mais-Ter--which contains 300 g/kg foramsulfuron + 10 g/kg iodosulfuron-methyl sodium + 300 g/kg isoxadifen-ethyl (safener); Terano--which contains 600 g/kg flufenacet + 25 g/kg metasulfuron; Mistral (standard)--which contains 40 g/l nicosulfuron. Each of these herbicides (in commercial form) was applied in four doses. The best results in the control of Sorghum halepense obtained by applying the Mistral herbicide. In second place from the point of you of its efficacy came the herbicide Mais-Ter and third place the herbicide Equip. The lowest degree of efficacy was recorded by the herbicide Terano. The grain yield in case of maize crops treated with before mentioned herbicides was in strict correlation with the efficacy of the herbicides and especially with the dose applied per hectare.

    Health literacy improves knowledge and builds skills to help individuals make appropriate decisions regarding their health. Over the past 20 years, several studies have described associations between health literacy and health outcomes. With respect to Romania, evidence is scarce on the level of health literacy, as well as on its determinants. Thus, the objectives of this study were to briefly screen functional health literacy levels in a sample of rural inhabitants, to assess the relationship between health literacy and reported health status, as well as to explore health literacy determinants within this population. Data were collected between September-November 2010, in four villages in Cluj County, Romania, using a cross-sectional survey. The mean age of respondents in the sample was 56 years, with roughly half of respondents being retired. The brief screening of health literacy suggested inadequate to marginal levels within the sample. Significant associations were observed between health literacy score and education, and self-perceived health status, whereas the relationship between health literacy and gender, and the presence of a chronic disease was not statistically significant. Limited health literacy has been shown to be common in people who rated their health as poor, those who attended only middle school, and individuals lacking basic information about their body. In order to minimize the adverse effects of low health literacy on health and health outcomes, efforts should be invested in identifying and addressing the health needs of adults with low and marginal health literacy, especially in underserved areas such as rural and remote settings, where access to health-related information is limited.

    Inland epigean freshwater amphipods of Romania are diverse and abundant for this region has a favourable geographical position between the Balkans and the Black Sea. Excluding Ponto-Caspian species originating in brackish waters and freshwater subterranean taxa, there are 11 formally recognized epigean freshwater species recorded from this country. They belong to 3 genera, each representing a different family: Gammarus (Gammaridae, 8 species or species complexes), Niphargus (Niphargidae, 2 epigean species) and Synurella (Crangonyctidae, one species). Their large-scale distribution patterns nevertheless remain obscure due to insufficient data, consequently limiting biogeographical interpretations. We provide extensive new data with high resolution distribution maps, thus improving the knowledge of the ranges of these taxa. Gammarus species display substantial altitudinal variability and patchy, fragmented distribution patterns. They occur abundantly, particularly in springs and streams, from lowlands to sub-mountainous and mountainous regions. In the light of recent molecular research, we hypothesize that the complex geomorphological dynamics of the Carpathian region during the Late Tertiary probably contributed to their allopatric distribution pattern. Contrasting with Gammarus, the genera Niphargus and Synurella exhibit low altitudinal variability, broad ecological valences and overlapping distributions, being widespread throughout the lowlands. The current distribution of N. hrabei and N. valachicus seems to be linked to the extent of the Paratethys during the Early Pliocene or Pleistocene.

    In the context of an explosive increase in value of the damage caused by natural disasters, an alarming challenge in the third millennium is the rapid growth of urban population in vulnerable areas. Cities are, by definition, very fragile socio-ecological systems with a high level of vulnerability when it comes to environmental changes and that are responsible for important transformations of the space, determining dysfunctions shown in the state of the natural variables (Parker and Mitchell, 1995, The OFDA/CRED International Disaster Database). A contributing factor is the demographic dynamic that affects urban areas. The aim of this study is to estimate the overall vulnerability of the urban area of Bucharest in the context of the seismic hazard, by using environmental, socio-economic, and physical measurable variables in the framework of a spatial multi-criteria analysis. For this approach the capital city of Romania was chosen based on its high vulnerability due to the explosive urban development and the advanced state of degradation of the buildings (most of the building stock being built between 1940 and 1977). Combining these attributes with the seismic hazard induced by the Vrancea source, Bucharest was ranked as the 10th capital city worldwide in the terms of seismic risk. Over 40 years of experience in the natural risk field shows that the only directly accessible way to reduce the natural risk is by reducing the vulnerability of the space (Adger et al., 2001, Turner et al., 2003; UN/ISDR, 2004, Dayton-Johnson, 2004, Kasperson et al., 2005; Birkmann, 2006 etc.). In effect, reducing the vulnerability of urban spaces would imply lower costs produced by natural disasters. By applying the SMCA method, the result reveals a circular pattern, signaling as hot spots the Bucharest historic centre (located on a river terrace and with aged building stock) and peripheral areas (isolated from the emergency centers and defined by precarious social and economic

    The design criteria and constraints for the development of the management strategy for radioactive waste generated from operating and decommissioning of CANDU Nuclear Units from Cernavoda NPP in Romania, present many specific aspects. The main characteristics of CANDU type waste are its high concentrations of tritium and radiocarbon. Also, the existing management strategy for radioactive waste at Cernavoda NPP provides no treatment or conditioning for radioactive waste disposal. These characteristics embodied a challenging effort, in order to select a proper strategy for radioactive waste management at present, when Romania is an EU member and a signatory country of the Joint Convention on the Safety of Spent Fuel Management and on the Safety of Radioactive Waste Management. The helping of advanced countries in radioactive waste management, directly or into the frame of the international organizations, like IAEA, become solve the aforementioned challenges at adequate level.

    Population aging has started late in Romania but has increased rapidly in the last few decades. The share of the population aged 60 and over reached 17% in 1992 and the decline in fertility after 1989 will considerably increase this share in the future. The author provides a detailed analysis of the present economic and social situation of the elderly in Romania. Factors such as the economic crisis, and particularly the deterioration of the standard of living, the very low income (pension) level, the high rate of inflation, and the lack of appropriate medical care have pushed most of the aged population into poverty. According to recent surveys, 1.5 million people out of the 3.8 million aged 60 and over live below the poverty line.

    Cultural heritage objects have a major contribution to the historical patrimony of every country. In Romania, wooden churches are famous, they are mostly dated in between the XVth and XXth century, but unfortunately many of them have been destroyed, by natural or anthropic means. Therefore, the necessity of conservation and restoration has appeared, to the ones that still exist, as legacy for the future generations. In the present article, an Imperial Gate from a wooden church in Cluj County, Romania, has been investigated, using scientific techniques (FTIR and XRF). A 3D reconstruction has been performed, using similar colors with the original artwork, as resulted from the scientific investigation of the painting materials. A limited number of constituent materials have been used for this artwork, and the wood species used was lime, due to the ease of carving.

  13. Probabilistic river forecast methodology

    NASA Astrophysics Data System (ADS)

    Kelly, Karen Suzanne

    1997-09-01

    The National Weather Service (NWS) operates deterministic conceptual models to predict the hydrologic response of a river basin to precipitation. The output from these models are forecasted hydrographs (time series of the future river stage) at certain locations along a river. In order for the forecasts to be useful for optimal decision making, the uncertainty associated with them must be quantified. A methodology is developed for this purpose that (i) can be implemented with any deterministic hydrologic model, (ii) receives a probabilistic forecast of precipitation as input, (iii) quantifies all sources of uncertainty, (iv) operates in real-time and within computing constraints, and (v) produces probability distributions of future river stages. The Bayesian theory which supports the methodology involves transformation of a distribution of future precipitation into one of future river stage, and statistical characterization of the uncertainty in the hydrologic model. This is accomplished by decomposing total uncertainty into that associated with future precipitation and that associated with the hydrologic transformations. These are processed independently and then integrated into a predictive distribution which constitutes a probabilistic river stage forecast. A variety of models are presented for implementation of the methodology. In the most general model, a probability of exceedance associated with a given future hydrograph specified. In the simplest model, a probability of exceedance associated with a given future river stage is specified. In conjunction with the Ohio River Forecast Center of the NWS, the simplest model is used to demonstrate the feasibility of producing probabilistic river stage forecasts for a river basin located in headwaters. Previous efforts to quantify uncertainty in river forecasting have only considered selected sources of uncertainty, been specific to a particular hydrologic model, or have not obtained an entire probability

    Trichinellosis is a food-borne zoonosis caused by the parasitic nematode Trichinella, characterized by an extremely wide host range and geographical distribution. In Romania, it is recognized as one of the most serious zoonotic diseases. A cross-sectional study, covering all regions of Romania, was conducted in 2014 to investigate and update the prevalence of Trichinella infection among domestic pigs, wild boars, and bears. Additional, molecular identification of Trichinella species circulating among these animals was performed in order to establish the biogeography of Trichinella species within the seven geographical regions of Romania. For this, a total of 113,383 pigs raised in non-controlled housing conditions (backyards), 5596 hunted wild boars and 147 hunted bears were subjected to Trichinella analysis. The highest prevalence of Trichinella infections was found in bears (12.93%), followed by wild boars (1.66%) and domestic pigs (0.20%). Of 294 Trichinella isolates that tested positive by multiplex PCR, 219 (74.49%) were identified as Trichinella spiralis, 66 (22.45%) as Trichinella britovi, and 9 isolates (3.06%) as mixed infections of T. spiralis and T. britovi. T. spiralis was more prevalent in domestic pigs (165/228; 72.37%) than in game (63/228; 27.63%), while T. britovi showed a higher prevalence in game (50/75; 66.66%) than in domestic pigs (25/75; 33.33%). Moreover, the present study revealed a significant host- and area- related distribution of Trichinella species within the seven regions of Romania. Therefore, these findings are of epidemiological relevance, updating data on the prevalence and distribution of Trichinella species circulating among domestic and wild animals in South-Eastern Europe.

    During the last decades, Dirofilaria spp. infection in European dogs has rapidly spread from historically endemic areas towards eastern and northeastern countries, but little or no information is available from these geographical regions. The present study provides a picture of filarial infections in dogs from Romania and compares two tests for the diagnosis of Dirofilaria immitis. From July 2010 to March 2011, blood samples were collected from 390 dogs from nine counties of Romania and serological SNAP tests were performed for the detection of D. immitis antigen. The remaining blood clots were subsequently used for DNA extraction followed by multiplex PCR for assessing filarioid species diversity (i.e. D. immitis, Dirofilaria repens and Acanthocheilonema reconditum). Based on molecular detection, an overall prevalence of 6.92 % (n = 27; 95 % confidence interval (CI) 4.70-10.03 %) for D. repens, 6.15 % (n = 24; 95 % CI 4.07-9.14 %) for D. immitis and 2.05 % (n = 8; 95 % CI 0.96-4.16 %) for A. reconditum was recorded, with significant variations according to sampling areas. Coinfections of D. immitis and D. repens were recorded in 23.91 % (n = 11) positive dogs. A slightly higher prevalence for D. immitis was detected at the SNAP test (n = 28, 7.17 %; 95 % CI 4.91-10.33 %), but this difference was not statistically significant (p = 0.66). However, only 53.57 % (n = 15) of antigen-positive dogs were confirmed by PCR, while other dogs (n = 9) PCR positive for D. immitis were negative at the serology. The present study shows that Dirofilaria species are endemic in the southern and southeastern areas of Romania, This article also provides, for the first time, an epidemiological picture of the distribution of A. reconditum in Romania.

    Rivers provide society with numerous returns. These relate to both the passive and extractive uses of the resources embodied in river environments. Some returns are manifest in the form of financial gains whilst others are non-monetary. For instance, rivers are a source of monetary income for those who harvest their fish. The water flowing in rivers is extracted for drinking and to water crops and livestock that in turn yield monetary profits. However, rivers are also the source of non-monetary values arising from biological diversity. People who use them for recreation (picnicking, swimming, boating) also receive non-monetary returns. The use of rivers to yield these returns has had negative consequences. With extraction for financial return has come diminished water quantity and quality. The result has been a diminished capacity of rivers to yield (non-extractive) environmental returns and to continue to provide extractive values. A river is like any other asset. With use, the value of an asset depreciates because its productivity declines. In order to maintain the productive capacity of their assets, managers put aside from their profits depreciation reserves that can be invested in the repair or replacement of those assets. Society now faces a situation in which its river assets have depreciated in terms of their capacity to provide monetary and non-monetary returns. An investment in river "repair" is required.

    The probabilistic seismic hazard analysis for Romania is revisited within the framework of the BIGSEES national research project (http://infp.infp.ro/bigsees/default.htm) financed by the Romanian Ministry of Education and Scientific Research in the period 2012-2016. The scope of this project is to provide a refined description of the seismic action for Romanian sites according to the requirements of Eurocode 8. To this aim, the seismicity of all the sources influencing the Romanian territory is updated based on new data acquired in recent years. The ground-motion models used in the analysis, as well as their corresponding weights, are selected based on the results from several recent papers also published within the framework of the BIGSEES project. The seismic hazard analysis for Romania performed in this study are based on the traditional Cornell-McGuire approach. Finally, the results are discussed and compared with the values obtained in the recently completed SHARE research project. The BIGSEES and SHARE results are not directly comparable since the considered soil conditions are different—actual soil classes for BIGSEES and rock for SHARE. Nevertheless, the analyses of the seismic hazard results for 200 sites in Romania reveal considerable differences between the seismic hazard levels obtained in the present study and the SHARE results and point out the need for further analyses and thorough discussions related to the two seismic hazard models, especially in the light of a possible future harmonized hazard map for Europe.

    Considering the EU statements, Romania is engaged to endorse in the near future the IAEA relevant publications on geological repository (CNCANa), to update the Medium and Long Term National Strategy for Safe Management of Radioactive Waste and to approve the Road Map for Geological Repository Development. Currently, for example, spent fuel is wet stored for 6 years and after this period it is transported to dry storage in MACSTOR-200 (a concrete monolithic module) where it is intended to remain at least 50 years. The present situation for radioactive waste management in Romania is reviewed in the present paper. Focus will be done on existent disposal facilities but, also, on future facilities planned for storage / disposal of radioactive wastes. Considering specific data for Romanian radioactive waste inventory, authors are reviewing the advance in the radioactive waste management in Romania considering its particularities. The team tries to highlight the expected limitations and unknown data related with cementitious engineered barriers that has to be faced in the near future incase of interim storage or for the upcoming long periods of disposal.

    The influence of some climatic oscillations and sunspot number on river flows in Romania, Ukraine, and Moldova is verified by using standard wavelet analyses. The selected climate oscillations are Arctic Oscillation (AO), Antarctic Oscillation (AAO), East Atlantic Oscillation (EAO), East Atlantic/West Russia Oscillation (EAWRO), NINO3.4, North Atlantic Oscillation (NAO), Pacific/North America Oscillation (PNAO), Pacific Decadal Oscillation (PDO), Polar/Eurasia Oscillation (PEO), Scandinavian Oscillation (ScandO), Southern Oscillation (SO), and West Pacific Oscillation (WPO). Forty-five hydrological stations from an area of 45,000 km(2) were used in order to discover the spatial evolution of the periodicities found in rivers. The wavelet analysis is novel for the rivers in the study area. There is an important difference between the periodicities found in mountain and plateau areas and those found in the plain area. There is a general downstream increase in the confidence level of the identified periods, even if the atmospheric precipitation has more relevant periodicities in the mountain area. The periodicities can be grouped into two compact groups: 1-16.5 and 27.8-55.6 years. The correlation matrix of the global wavelet spectrum (GWS) values indicates that NAO, EAWRO, PDO, and the sunspot number are the main factors that generate the periodicities in rivers. It is the first time when the influence of PDO on local rivers is proven. All river periodicities smaller than 16 years have a confidence level of 0.95 or above, as proven by the GWS analysis of the daily discharge data, and are caused by multiple external factors.

    2010-05-01

    Vrancea area at the sharp bend of the Southeast Carpathians in Romania is one of the highest seismogenic zones in Europe, the present-day tectonic activity in this region being characterized by a small zone of intense shallow- to intermediate-depth seismicity that is often interpreted as reflecting the late stage of intra-continental collision. Efforts to advance understanding of earthquake physics and assessing of earthquake hazard in Vrancea seismic area require detailed observations of all phases of the earthquake cycle (pre-, co-, and post-seismic), across multiple fault systems and tectonic environment. Earthquake prediction has two potentially compatible but distinctly different objectives: (a) phenomena that provide information about the future earthquake hazard useful to those who live in earthquake-prone regions and (b) phenomena causally related to the physical processes governing failure on a fault that will improve our understanding of those processes. Remote sensing and geospatial information tools and techniques, including numerical modeling, have advanced considerably in recent years, enabling a greater understanding of the Earth as a complex system of geophysical phenomena. Space-based geodetic measurements using the Global Positioning System in synergy with ground-based seismological measurements, interferometric synthetic aperture radar data, high-resolution digital elevation models as well imaging spectroscopy (e.g. using ASTER, MODIS and Hyperion data) are contributing significantly to seismic hazard and risk assessment. Space-time anomalies of Earth's emitted radiation (radon in underground water and soil and surface air , thermal infrared in spectral range measured from satellite months to weeks before the occurrence of earthquakes etc.), ionospheric and electromagnetic anomalies have been interpreted, by several authors, as pre-seismic signals. For seismic hazard analysis in Vrancea area, Romania have been selected the earthquake precursors

Purple shadows hang in the lee of the peaks, giving the snow-clad land a crumpled appearance. White gives way to brown on the right side of the image where the mountains yield to the lower-elevation Susitna River Valley. The river itself cuts a silver, winding path through deep green forests and brown wetlands and tundra. Extending from the river valley, are smaller rivers that originated in the Alaska Mountains. The source of these rivers is evident in the image. Smooth white tongues of ice extend into the river valleys, the remnants of the glaciers that carved the valleys into the land. Most of the water flowing into the Gulf of Alaska from the Susitna River comes from these mountain glaciers. Glacier melt also feeds glacier lakes, only one of which is large enough to be visible in this image. Immediately left of the Kahiltna River, the aquamarine waters of Chelatna Lake stand out starkly against the brown and white landscape.

    The world's river dolphins (Inia, Pontoporia, Lipotes and Platanista) are among the least known and most endangered of all cetaceans. The four extant genera inhabit geographically disjunct river systems and exhibit highly modified morphologies, leading many cetologists to regard river dolphins as an unnatural group. Numerous arrangements have been proposed for their phylogenetic relationships to one another and to other odontocete cetaceans. These alternative views strongly affect the biogeographical and evolutionary implications raised by the important, although limited, fossil record of river dolphins. We present a hypothesis of river dolphin relationships based on phylogenetic analysis of three mitochondrial genes for 29 cetacean species, concluding that the four genera represent three separate, ancient branches in odontocete evolution. Our molecular phylogeny corresponds well with the first fossil appearances of the primary lineages of modern odontocetes. Integrating relevant events in Tertiary palaeoceanography, we develop a scenario for river dolphin evolution during the globally high sea levels of the Middle Miocene. We suggest that ancestors of the four extant river dolphin lineages colonized the shallow epicontintental seas that inundated the Amazon, Paraná, Yangtze and Indo-Gangetic river basins, subsequently remaining in these extensive waterways during their transition to freshwater with the Late Neogene trend of sea-level lowering.

    The current study focus on the coralline algae from the Middle Miocene limestones in NW Transylvania to provide an outline for their systematics and palaeoecology. The investigated samples were collected from three carbonate outcrops: Vǎlenii Șomcutei, Ciolt 1 and Ciolt 2, named after the respective localities situated in the vicinity of the Țicǎu-Preluca Mountains (NW Romania). The microfacies analysis suggest shallowing upward tendency in middle to proximal shelf environments. The coralline algae are present in the carbonate successions as detritus, branches, crusts and rhodoliths. The Vǎlenii Șomcutei section shows a depositional model where large and spheroidal rhodoliths develop in high energy conditions, most probably generated by storm waves. The sections from the Ciolt area are distinguished by the presence of green algae in association with the encrusting and geniculate coralline specimens. The identified species belong to Ord. Corallinales (Hydrolithon, Spongites, Lithophyllum, Jania), Hapalidales (Lithothamnion and Mesophyllum) and Sporolithales (Sporolithon). In the taxonomic identification of coralline red algae we used as many diagnostic features as possible, known from the description of present - day species, such as: shape of epithallial cells and roof morphology for melobesioids; presence/absence of a layer of elongated cells below sporangial compartments and number of cells in paraphyses for sporolithoids. The identified coralline algal assemblages are discussed according to different paleoenvironmental conditions (paleo-depth, hydrodynamic energy) and then compared with similar fossil assemblages and recent analogs like modern maërl and rhodolith pavements.

    Keywords: heavy metals, soil contamination, bioavailability, Romania The fate of various metals, including chromium, nickel, copper, manganese, mercury, cadmium, and lead, and metalloids, like arsenic, antimony, and selenium, in the natural environment is of great concern, particularly in the vicinity of former mining sites, dumps, tailings piles, and impoundments, but also in urban areas and industrial centres. Most of the studies focused on the heavy metal pollution in mining areas present only the total amounts of metals in soils. The bioavailable concentration of metals in soil may be a better predictor for environmental impact of historical and current dispersion of metals. Assessment of the metal bioavailability and bioaccessibility is critical in understanding the possible effects on soil biota. The bioavailability of metals in soil and their retention in the solid phase of soil is affected by different parameters like pH, metal amount, cation-exchange capacity, content of organic matter, or soil mineralogy. The main objectives of the present study were to determine the total fraction and the bioavailable fraction of Cu, Cd, Pb and Zn from soil in a well-known mining region in Romania, and to evaluate the influence of soil pH on the metal bioavailability in soil. The heavy metal contents and their bioavailability were monitored in a total of 50 soil samples, collected during June and July 2014 from private gardens of the inhabitants from Baia-Mare area. The main mining activities developed in the area consisted of non-ferrous sulphidic ores extraction and processing, aiming to obtain concentrates of lead, copper, zinc and precious metals. After 2006, the metallurgical industry has considerably reduced its activity by closing or diminishing its production capacity. The analysed soil samples proved to have high levels of Pb (50 - 830 mg/kg), Cu (40 - 600 mg/kg), Zn (100 - 700 mg/kg) and Cd (up to 10 mg/kg). The metal abundance in the total fraction is

    The purpose of this meta-study was to investigate β-thalassemia (β-thal) mutations and their chromosomal background in order to highlight the origin and spread of thalassemia alleles in the European and Mediterranean areas. Screening of more than 100 new Romanian β-thal alleles was also conducted. The results suggest an ancient introduction of mutations at codon 39 (C > T) (HBB: c.118C > T) and IVS-I-6 (T > C) (HBB: c.92 + 6T > C) in Romania. A comparative study was performed based on restriction fragment length polymorphism (RFLP) haplotypes associated with β-thal mutations in Romania and in Mediterranean countries. Each common β-thal allele from different populations exhibits a high degree of haplotype similarity, a sign of a clear unicentric origin for the IVS-I-110 (G > A) (HBB: c.93-21G > A), IVS-I-6, IVS-II-745 (C > G) (HBB: c.316-106C > G) and codon 39 mutations (the 17a [+ - - - - + +], 13c [ - + + - - - +], 17c [ + - - - - - +] and 14a [- + + - + + + ] ancestral RFLP background, respectively), followed by recurrent recombination events. This study also showed that geographic distances played a major role in shaping the spread of the predominant β-thal alleles, whereas no genetic boundaries were detected between broad groups of populations living in the Middle East, Europe and North Africa. The analyses revealed some discrepancies concerning Morocco and Serbia, which suggest some peculiar genetic flows. Marked variations in β(A) were observed between Southeast Asia and the Mediterranean, whereas a relative genetic homogeneity was found around the Mediterranean Basin. This homogeneity is undoubtedly the result of the high level of specific historic human migrations that occurred in this area. PMID:26711012

    Since 2006 a modern laboratory has been developed by IFIN-HH in the underground of Slanic Prahova salt ore. This work presents a short review of previous scientific activities performed in the underground laboratory, in parallel with some plans for the future. A mobile detector for cosmic muon flux measurements has been set up at IFIN-HH, Romania. The device is used to measure the muon flux on different locations at the surface and underground and it consists of two detection layers, each one including four large scintillator plates. A new rotatable detector for measurements of the directional variation of the muon flux has been designed and it is presently under preliminary tests. Built from four layers of sensitive material and using for collecting the signals and directing them to the micro PMTs a new technique, through optical fibers instead wave length shifters, it allows an easy discrimination of the moun flux on the arrival directions of muons. Combining the possibility to rotate and the directionality properties, the underground muon detector is acting like a muon tomography device, being able to scan, using cosmic muons, the rock material above the detector. In parallel new detection system based on SiPM will be also installed in the following weeks. It should be composed by four layers, each layer consisting in 4 scintillator plates what we consider in the following as a module of detection. For this purpose, first two scintillator layers, with the optical fibers positioned on perpendicular directions are put in coincidence with other two layers, 1 m distance from the first two, with similar optical fiber arrangement, thus allowing reconstructing muon trajectory. It is intended also to design and construct an experimental device for the investigation of such radio antennas and the behavior of the signal in rock salt at the Slanic salt mine in Romania. Another method to detect high energy neutrinos is based on the detection of secondary particles resulting

  16. Sexual behaviour and sexual and reproductive health education: a cross-sectional study in Romania

    2014-01-01

    Background Up-to-date, genuine sexual and reproductive health (SRH) education programmes have been possible in Romania only since communism collapsed in 1990. Since 2006, Romania has had no national strategy in this field. Under current global circumstances (high labour mobility, internationally mixed marriages), issues previously considered solely national have become worldwide concerns. Methods In 2011–2012, 1215 respondents homogeneously distributed on background, gender, educational level and age group (18–74) were sampled. This article uses a 96-item questionnaire about family and SRH, presenting results on nine items: first intercourse (FI), virginity, knowing first sexual partner, safe sex, number of sexual partners and sexual education. The data were analysed using Pearson chi-square tests and latent class analysis. Results Some participants (7.2%) engaged in FI at age 15 or earlier. The average age at FI was lower for men (18.08), for individuals with a lower education level (18.07) and for those in rural areas (18.27), compared with that for women, those with more education and those in urban areas, respectively. The average age at FI was over 2.5 years lower for people aged 18–24 (16.99) than for those aged 60–74 (p < 0.001). More than 60% were not married or partnered with their FI partner, and 17.8% engaged in FI less than a month after meeting their partner. Less than one-fourth practiced safe sex at FI, with higher proportions for the urban sample, those with an average level of education and those aged 18–35 (p < 0.001). Higher average numbers of sexual partners were found among men (6.56, compared with 2.37 among women), in urban areas (5.07, compared with 3.75 in rural areas) and among those with higher levels of education (p < 0.005). On average, subjects first received information on SRH at 15.39 years of age, with only 10% listing the school, doctors or medics as a source. Conclusions Unsafe sex, early initiation of

    Landslides are widespread natural phenomena that shape the earth surface. As such, they are part of the environment where people live, playing an important role as natural hazard, but also making a place peculiar for its specific morphology. Nowadays, like in the past, people living in hilly to mountainous areas have always had to face landslides. In the Eastern Carpathians lowlands, landslides have carved a landscape with inaccessible escarpments tens of meters high, providing old populations with panoramic and naturally defensive places to build their settlements. This interaction produced an association of landslide morphologies and archaeological remains that is unique in Romaina. In this study, we present the case of chalcolitic and thraco-getic (6.5 ka BP to 500 BP) fortified settlements, for which landslides provided a favorable place for their construction on one hand, and acted as a natural hazard on the other hand. In the Moldavian Plateau, North-Eastern Romania, more than 50 sites were identified on structural plateaus bounded by wide scarps of Pleistocene landslides, on cuesta ridges bounded by scarps of Holocene landslides, or situated on hillslopes, on erosional remnants of landslide bodies. For nine out of the 50 sites, we produced accurate geomorphological landslide inventories, mapping more than 500 landslides starting from high resolution LiDAR DEM derived images. Such inventories provide information on landslide type and relative ages (very old, old, recent landslides) based on the morphological appearance of each slope failure. Analysis of the relations between the sites hosting the fortified settlements, their archaeological remains and very old landslides distribution, provides evidences that landslide scarps and their deposits were used by these populations as defensive sites. In particular, the scarps were used as natural walls, allowing to save material and manpower required to erect walls on the gentle and open parts of the sites. Besides

    The aim of this paper is to investigate the connection between climate extremes (temperature and precipitation) in Romania and large-scale air circulation. Daily observational data of maximum air temperature and amount of precipitation for the period 1961-2010 were used to compute two seasonal indices associated with temperature and precipitation, quantifying their frequency, as follows: frequency of very warm days (FTmax90 ≥ 90th percentile), frequency of very wet days (FPp90; daily precipitation amount ≥ 90th percentile). Seasonally frequency of circulation types were calculated from daily circulation types determined by using two objective catalogues (GWT - GrossWetter-Typen and WLK - WetterLargenKlassifikation) from the COST733Action. Daily reanalysis data sets (sea level pressure, geopotential height at 925 and 500 hPa, u and v components of wind vector at 700 hPa and precipitable water content for the entire atmospheric column) build up by NCEP/NCAR, with 2.5°/2.5° lat/lon spatial resolution, were used to determine the circulation types. In order to select the optimal domain size related to the FTmax90 and the FPp90, the explained variance (EV) has been used. The EV determines the relation between the variance among circulation types and the total variance of the variable under consideration. This method quantifies the discriminatory power of a classification. The relationships between climate extremes in Romania and large-scale air circulation were investigated by using multiple linear regression model (MLRM), the predictands are FTmax90 and FPp90 and the circulation types were used as predictors. In order to select the independent predictors to build the MLRM the collinearity and multicollinearity analysis were performed. The study period is dividend in two periods: the period 1961-2000 is used to train the MLRM and the period 2001-2010 is used to validate the MLRM. The analytical relationship obtained by using MLRM can be used for future projection

    At present, two seismic arrays are installed on the Romanian territory and record continuously the ground motion and send the data in real time to the National Data Center, in Magurele, Romania. One array is located in the Northern part of the country, in Bucovina (BURAR array), while the second one (Plostina - PLOR array) is situated right above the Vrancea seismic nest, the region with the highest seismic activity in Romania. The BURAR array consists of ten stations with seismic sensors installed in boreholes at depths of 30 and 50 m, covering an area of 5x5 km2. Nine stations are equipped with GS21 short period vertical sensors and one station has a 3-component broadband sensor (KS54000). In 2008, three more 3-component broadband sensors (CMG-40T) were installed at surface; two of them collocated with existing sites and one in a different site. The PLOR array consists of 7 elements equipped with 3-component broadband sensors (CMG40T - 6 and STS2 - 1). The aperture of the array is 2.5 km, with a distance between inner elements of 250 m and 1100 m for the outer elements. We analyze the power spectral density of BURAR and PLOR arrays continuous records to characterize the temporal noise variations and investigate their influence on the detection capabilities for intermediate-depth earthquakes, occurred in Vrancea region, as well as for local crustal events produced in various places of the country. We also perform polarization and array specific analyses to identify the main sources of the high frequency noise and secondary microseisms. Diurnal variations caused by anthropogenic activities have been observed at all stations, but their significance depends strongly on the distance to the sources of the noise. For BURAR array, the maximum difference between nighttime and daytime noise levels is 25 dB, while for PLOR array we observe differences up to 42 dB. In the microseismic band, the noise variations are correlated well with the seasons and have their maximum

    This study focuses on future forest cover change in Buzau Subcarpathians, a landslide prone region in Romania. Past and current trends suggest that the area might expect a future increase in deforestation. We developed spatially explicit scenarios until 2040 to analyze the spatial pattern of future forest cover change and potential changes to landslide risk. First, we generated transition probability maps using the weights of evidence method, followed by a cellular automata allocation model. We performed expert interviews, to develop two future forest management scenarios. The Alternative scenario (ALT) was defined by 67 % more deforestation than the Business as Usual scenario (BAU). We integrated the simulated scenarios with a landslide susceptibility map. In both scenarios, most of deforestation was projected in areas where landslides are less likely to occur. Still, 483 (ALT) and 276 (BAU) ha of deforestation were projected on areas with a high-landslide occurrence likelihood. Thus, deforestation could lead to a local-scale increase in landslide risk, in particular near or adjacent to forestry roads. The parallel process of near 10 % forest expansion until 2040 was projected to occur mostly on areas with high-landslide susceptibility. On a regional scale, forest expansion could so result in improved slope stability. We modeled two additional scenarios with an implemented landslide risk policy, excluding high-risk zones. The reduction of deforestation on high-risk areas was achieved without a drastic decrease in the accessibility of the areas. Together with forest expansion, it could therefore be used as a risk reduction strategy.

    We present our experience regarding the establishing of an interdisciplinary group with Optics as one of its main topic at the Aurel Vlaicu University of Arad (UAVA) - linked with the improvement through research of our educational activities. The 3OM Group (in Opto-Mechatronics, Optical Metrology, and Optics and Mechanics) is described in its evolution from optomechanics to photonics, the latter with a focus on OCT (Optical Coherence Tomography) - with the national and the international collaborations established, with universities from Romania, Europe and USA. While the research directions of the 3OM Group are presented, they are linked with the educational components implemented in the various subjects we teach, for both undergraduate and graduate students, both in Mechanical and in Electrical Engineering. The main effort is to integrate education and research, to move teaching beyond the classical aspects to put the stress on hands-on-experiments, as well as on research-based activities - even with undergraduates. The main goals of this approach are to obtain an early orientation towards innovation and discovery, with a taste for novelties and with a clear focus on international standards. While this account is only one of many, it offers our experience in passing through the difficulties of developing both research and education in Optics in a young university in an emergent economy in Eastern Europe.

    1993-09-01

    During the Alpine evolution of Romania, two distinct depositional areas evolved in the external zones of the Carpathians: the Paleogene flysch and Neogene Molasse basin of the eastern Carpathians, and the Paleogene and Neogene Molasse basin of the southern Carpathians. Both basins were compressionally deformed during the Neogene, giving rise to the development of a succession of nappes and thrust sheets. The internal elements of the external Carpathians corresponding to the Tarcau and marginal folds nappes and the external elements forming the sub-carpathian nappe and foredeep were thrusted over significant distances onto the European platform. Intense exploration of the external Carpathian thrustbelt has led to the discovery of more than 100 oil and gas pools. Reservoirs are provided by Oligocene, Burdigalian, Sarmatian, and Pliocene clastic rocks. A prolific hydrocarbon charge is derived from regionally distributed Oligocene oil source rocks. Traps are mainly of the structural type and involve faulted anticlines, [open quotes]scale folds,[close quotes] and compressional structures modified by salt; stratigraphic pinch-out and unconformity related traps play a secondary role. On the basis of selected examples, the development and distribution of hydrocarbon pools will be discussed in terms of thrust kinematics and the structure of different platform blocks. The philosophy of past exploration activities will be reviewed, and both success cases and failures will be discussed. Remaining oil and gas plays, aimed at shallow as well as at deep objectives, will be highlighted.

    Oil and gas fields located in Moldavic nappes are encompassed in Oligocene and lower Miocene formations, mostly in the marginal folds nappe, where Kliwa Sandstone sequences have high porosity, and in the Black Sea Plateau. The origin of the hydrocarbon accumulations from the Carpathian foredeep seems to be connected to the Oligocene-lower Miocene bituminous formations of the marginal folds and sub-Carpathian nappes. In the Gethic depression, the hydrocarbon accumulations originate in Oligocene and Miocene source rocks and host in structural, stratigraphical, and lithological traps. The accumulations connected with tectonic lines that outline the areal extension of the Oligocene, Miocene, and Pliocene formations are in the underthrusted Moesian platform. The hydrocarbon accumulations related to the Carpathian foreland represent about 40% of all known accumulations in Romania. Most of them are located in the Moesian platform. In this unit, the oil and gas fields present a vertical distribution at different stratigraphic levels, from paleozoic to Neogene, and in all types of reservoirs, suggesting multicycles of oleogenesis, migration, accumulation, and sealing conditions. The hydrocarbon deposits known so far on the Black Sea continental plateau are confined in the Albian, Cenomanian, Turonian-Senonian, and Eocene formations. The traps are of complex type structural, lithologic, and stratigraphic. The reservoirs are sandstones, calcareous sandstones, limestones, and sands. The hydrocarbon source rocks are pelitic and siltic Oligocene formations. Other older source rocks are probably Cretaceous.

    With the development of space-based technologies to measure surface geophysical parameters and deformation at the boundaries of tectonic plates and large faults, earthquake science has entered a new era. Using time series satellite data for earthquake prediction, it is possible to pursue the behaviors of earthquake precursors in the future and to announce early warnings when the differences between the predicted value and the observed value exceed the pre-define threshold value. Starting with almost one week prior to a moderate or strong earthquake a transient thermal infrared rise in LST of several Celsius degrees (oC) and the increased OLR values higher than the normal have been recorded around epicentral areas, function of the magnitude and focal depth, which disappeared after the main shock. Also are recorded associated geomagnetic and ionospheric distrurbances. Vrancea tectonic active zone in Romania is characterized by a high seismic hazard in European- Mediterranean region, being responsible of strong or moderate intermediate depth and normal earthquakes generation on a confined epicentral area. Based on recorded geophysical parameters anomalies was developed an integrated geospatial system for earthquake precursors assessment in Vrancea active seismic zone. This system integrates derived from time series MODIS Terra/Aqua, NOAA-AVHRR, ASTER, Landsat TM/ETM satellite data multi geophysical parameters (land surface temperature -LST, outgoing long-wave radiation- OLR, and mean air temperature- AT as well as geomagnetic and ionospheric data in synergy with in-situ data for surveillance and forecasting of seismic events.

    A 3 MV Tandetron™ accelerator system has been installed and commissioned at the "Horia Hulubei" National Institute for Physics and Nuclear Engineering - IFIN-HH, Măgurele, Romania. The main purpose of this machine is to strengthen applied nuclear physics research ongoing in our institute for more than four decades. The accelerator system was developed by High Voltage Engineering Europa B.V. (HVE) and comprises three high energy beam lines. The first beam line is dedicated to ion beam analysis (IBA) techniques: Rutherford Backscattering Spectrometry - RBS, Nuclear Reaction Analysis - NRA, Particle Induced X-ray and γ-ray Emission - PIXE and PIGE and micro-beam experiments - μ-PIXE. The second beam line is dedicated to high energy ion implantation experiments and the third beam line was designed mainly for nuclear cross-sections measurements used in nuclear astrophysics. A unique feature, the first time in operation at an accelerator facility is the Na charge exchange canal (CEC), which is used to obtain high intensity beams of He- of at least 3 μA. The results of the acceptance tests demonstrate the huge potential of this new facility in various fields, from IBA to radiation hardness studies and from medical or environmental applications to astrophysics. The main features of the accelerator are presented in this paper.

The radium concentration in water was determined, with the same device, immediately after was established the radon equilibrium with radium. The results presented here are from a survey carried out in the N-W region of Transylvania (Romania) in which were investigated the radon concentrations in natural (spring, well and surface) and drinking (tap) waters. The results showed radon concentrations within the range of 0.4-187.3 Bq l(-1) with an average value of 15.9 Bq l(-1) whereas radium concentration varied between 0.05 and 0.825 Bq l(-1) with an average value of 0.087 Bq l(-1) for all types of water covered within this survey. The corresponding annual effective ingestion dose due to radon and radium from water was determined from drinking water used by the population inhabiting the area.

    Paclele Mici is a terrestrial mud volcano field located in the Carpathian Mountains (Romania), where thermal alteration of sedimentary organic compounds leads to methane, higher hydrocarbons and other petroleum compounds that are continuously released into the environment. The hydrocarbons represent potential substrates for microorganisms. We studied lipid biomarkers, stable isotope ratios, the effect of substrate (methane, other organic compounds) addition and 16S rRNA genes to gain insights into the hitherto unknown microbial community at this site. Quantitative real-time polymerase chain reaction analysis demonstrated that bacteria were much more abundant than archaea. Phylogenetic analyses of 16S rDNA clone sequences indicated the presence of bacterial and archaeal lineages generally associated with the methane cycle (methanogens, aerobic and anaerobic methanotrophs), the sulfur cycle (sulfate reducers), and groups linked to the anaerobic degradation of alkanes or aromatic hydrocarbons. The presence of sulfate reducers, methanogens and methanotrophs in this habitat was also confirmed by concurrent surveys of lipid biomarkers and their isotopic signatures. Incubation experiments with several common and complex substrates revealed the potential of the indigenous microbial community for sulfate reduction, methanogenesis and aerobic methanotrophy. Additionally, consistently to the detection of methane-oxidizing archaea (ANME) and 13C-depleted archaeal lipids, a weak but significant activity of anaerobic methane oxidation was measured by radiotracer techniques and in vitro. This survey is the first to report the presence and activity of ANME in a terrestrial environment.

On a regional scale, forest expansion could so result in improved slope stability. We modeled two additional scenarios with an implemented landslide risk policy, excluding high-risk zones. The reduction of deforestation on high-risk areas was achieved without a drastic decrease in the accessibility of the areas. Together with forest expansion, it could therefore be used as a risk reduction strategy.

    This paper highlights the statistical methodology used in a dissection experiment carried out in Romania to calibrate and standardize two classification devices, OptiGrade PRO (OGP) and Fat-o-Meat'er (FOM). One hundred forty-five carcasses were measured using the two probes and dissected according to the European reference method. To derive prediction formulas for each device, multiple linear regression analysis was performed on the relationship between the reference lean meat percentage and the back fat and muscle thicknesses, using the ordinary least squares technique. The root mean squared error of prediction calculated using the leave-one-out cross validation met European Commission (EC) requirements. The application of the new prediction equations reduced the gap between the lean meat percentage measured with the OGP and FOM from 2.43% (average for the period Q3/2006-Q2/2008) to 0.10% (average for the period Q3/2008-Q4/2014), providing the basis for a fair payment system for the pig producers.

    The Early Triassic witnessed the highest taxic diversity of coelacanths (or Actinistia), a clade with a single living genus today. This peak of diversity is accentuated here with the description of a new coelacanth discovered in the lower Spathian (Upper Olenekian, Lower Triassic) cropping out in the Tulcea Veche (Old Tulcea) promontory, in the city of Tulcea, in North Dobrogea, Romania. The bone remains were preserved in a block of limestone, which was chemically dissolved. The resulting 3D and matrix-free ossifications correspond mostly to elements of the skull and branchial apparatus. Posterior parietals, postparietal with associated prootic and basisphenoid allow a precise description of the neurocranium. Ossifications of the lower jaw, together with branchial and pectoral elements, complete the description of this coelacanth and support the coining of a new generic and specific name, Dobrogeria aegyssensis. A phylogenetic analysis of actinistians with the new species recovers clades which were found in most recent analyses, i.e. the Sasseniidae, the Laugiidae, the Coelacanthiformes, the Latimerioidei, the Mawsoniidae and the Latimeriidae, and identifies the new taxon as a non-latimerioid coelacanthiform.

    The 14-MW TRIGA steady state reactor (SSR) located in Pitesti, Romania, first went critical in the fall of 1979. Initially, the core configuration for full power operation used 29 fuel clusters each containing a 5 {times} 5 square array of HEU (10 wt%) -- ZrH -- Er (2.8 wt%) fuel-moderator rods (1.295 cm o.d.) clad in Incology. With a total inventory of 35 HEU fuel clusters, burnup considerations required a gradual expansion of the core from 29 to 32 and finally to 35 clusters before the reactor was shut down because of insufficient excess reactivity. At this time each of the original 29 fuel clusters had an overage {sup 235}U burnup in the range from 50 to 62%. Because of the US policy regarding the export of highly enriched uranium, fresh HEU TRIGA replacement fuel is not available. After a number of safety-related measurements, the SSR is expected to resume full power operation in the near future using a mixed core containing five LEU TRIGA clusters of the same geometry as the original fuel but with fuel-moderator rods containing 45 wt% U (19.7% {sup 235}U enrichment) and 1.1 wt% Er. Rods for 14 additional LEU fuel clusters will be fabricated by General Atomics. In support of the SSR mixed core operation numerous neutronic calculations have been performed. This paper presents some of the results of those calculations.

    The geopark Buzăului County does not belong to the Geoparks European Network, as there are numerous governmental, legislative and scientific initiatives in this respect. The geopark is situated in the central-south-eastern part of Romania (in Buzau county) and it has a special potential of geological, geomorphological, biogeographical and anthropic nature, a potential which has to be developed and brought into value. The idea of creating a geopark in this area is relatively recent and it was realized by a series of actions carried on by local authorities in partnership with several institutions, a partnership within which it was accomplished the proposal of a general development framework of the geopark, as well as the launching of a promotion campaign. The scope of this work is to evaluate the geodiversity existing in this space as an important starting point in declaring it as a European geopark, being known that it represents a real "open air museum". The high values of geodiversity and biodiversity represent special strong points in this respect. The method we used was taken from the specialised literature, suffering a series of adjustments to the specifics of the studied area. In the present format, the method is applied for the first time in the Geography literature, so the values obtained cannot be compared with those obtained by other calculation formulas. Thus, values between 0.20 and 1.91 which resulted cover the entire scale of variables proposed.

    A set of 36 ceramic shards excavated at Hârşova, Romania, dated to the 11th century A.D., was investigated using Optical Microscopy (OM) and PIXE (Particle Induced X-ray Emission). The study aimed at revealing the raw materials and the manufacturing techniques employed by the potters from the Lower Danube zone during the Byzantine period and to distinguish the local products from the supposedly imported ones. The division of the ceramic shards based on stylistic grounds was refined by the petrographic observations that identified four types of fabrics. Principal Component Analysis (PCA) of the PIXE data singled out two categories of ceramic: one made from kaolinitic clays and another produced from local sedimentary resources, with or without temper addition. Micro-PIXE scans of the interfaces between the green glaze and the underlying ceramic body indicated a high Pb content in the decorative layers. Glazing was made through the application of PbO onto a non-calcareous clay body. The petrographic and compositional data interpreted in correlation with archaeological information led to the characterization of a representative assemblage of ceramic finds from the Byzantine period, subject rarely tackled in the scientific literature.

    This case study describes the first genetically confirmed and clinically manifested autochthonous Ehrlichia canis infection in a 9-year-old female mixed-breed dog from Romania. Health screening of the dog included clinical examination, evaluation of stained peripheral blood smear and hematologic variables, as well as serologic testing and molecular analysis. Clinical signs included fever, apathy, dehydration, pale mucous membranes, and weakness. The microscopic examination of the blood smear and immunologic assays for Borrelia burgdorferi, Anaplasma phagocytophilum, and E canis antibodies, and for Dirofilaria immitis antigen yielded negative results. Hematologic abnormalities included moderate nonregenerative anemia, leucopenia with neutropenia, and moderate thrombocytopenia. The biochemical abnormalities identified were hypoalbuminemia, and mildly increased serum enzyme activities of AST and ALT. In addition, increased urea and creatinine levels associated with low urine specific gravity and proteinuria were also present. Nested PCR amplification of the partial E canis 16S rRNA gene demonstrated the presence of this rickettsial pathogen in the dog's blood, which subsequently was confirmed through sequencing based on the 100% homology with GenBank deposited E canis isolates. After specific treatment with doxycycline (10 mg/kg, orally, SID) for one month, the proteinuria, and hematologic and serum biochemical abnormalities with the exception of mild azotemia resolved. This report supports the geographical expansion of canine ehrlichiosis caused by E canis in nonendemic regions of Europe. PMID:25867940

    Soil contamination in recreational areas can considerably affect children's health, as they are the segment of the population most sensitive to anthropogenic contamination. Soil contamination in recreational areas is influenced by a number of factors such as type and age of the recreational area, nearby traffic intensity, proximity to industrial areas, presence of vegetation, level of usage, treated wood structures, and the extent of maintenance operations carried out in the area. These can most often be observed during a simple site visit. The purpose of the present research is to analyze to which extent the presence of these factors can trigger an alarm signal, highlighting soil contamination in urban recreational areas. In this regard, soil contamination was scaled using the integrated pollution index applied on nine distinctive contaminants (As, Cu, Cd, Zn, Pb, Hg, Co, Ni, Mg) identified using inductively coupled plasma mass spectrometry (ICP-MS). Multiple linear regression analysis was performed in order to assess predictors of soil contamination. The research was carried out in a number of 88 recreational areas, parks, and playgrounds from 19 Romanian cities, revealing the fact that proximity to industrial areas and intensive traffic had statistically significant effects on soil contamination. Furthermore, it was observed that in 78 out of the 88 analyzed locations, the concentrations of contaminants exceeded the guidelines established through national legislation, thus confirming the presumption that high concentrations of contaminants exist in the parks and playgrounds of Romania.

    Creating precise climatic maps (temperature and precipitation map especially) on small areas such as drainage basins or landform units is always very useful for ecology of plants, distribution of vegetation and also different types of agricultural land. The geographic information system (GIS) analysis of several key-factors (aspect and slope of terrain, insolation degree, thermal gradient, geology and structure of landforms) offers the necessary tools to operate with in order to create an accurate climatic map. This method was applied in order to create a map showing the distribution of temperatures in the Olanesti drainages basin, a 235 km2 area located at middle latitude, in Romania. After creating the DEM, aspect and slope of the terrain, reclassifying categories and calculating the thermal gradient, a map showing the distribution of the annual mean temperature is obtained. Other climatic parameters could be calculated for small areas too, with precise results. These demonstrate that not only elevation and mathematical location of an area are important factors in the distribution of temperature, but also the aspect, the gradient, the insolation, the type of rock and the structure.

    Measurements of 131I (T1/2 = 8.04 days) activities have been performed in the IFIN HH (Horia Hulubei National Institute of Physics and Nuclear Engineering) underground laboratory situated in Unirea salt mine, Slănic-Prahova, Romania. The rainwater samples were collected starting on 27 March from Braşov and Slănic-Prahova. Also sheep and goat milk samples were collected in the Slănic, Braşov and Iaşi areas and measurements were subsequently made on them. The measurements on the samples were made at the IFIN HH's underground laboratory in an ultra-low radiation background, using a high resolution gamma-ray spectrometer equipped with a GeHP (hyperpure) detector having a full width at half-maximum of 1.80 keV at 1332.48 keV for the second 60Co gamma ray and a relative efficiency of 22.8%. The results show a specific activity of 131I from < 0.063 to 0.75 Bq l - 1 for rain. In the milk samples the specific activity varied from < 0.12 to 5.2 Bq l - 1.

    Neanderthals are thought to have disappeared in Europe ~39,000–41,000 years ago but they have contributed one to three percent of the DNA of present-day people in Eurasia1. Here, we analyze DNA from a 37,000–42,000-year-old2 modern human from Peştera cu Oase, Romania. Although the specimen contains small amounts of human DNA, we use an enrichment strategy to isolate sites that are informative about its relationship to Neanderthals and present-day humans. We find that on the order of six to nine percent of the genome of the Oase individual is derived from Neanderthals, more than any other modern human sequenced to date. Three chromosomal segments of Neanderthal ancestry are over 50 centimorgans in size, indicating that this individual had a Neanderthal ancestor as recently as four to six generations back. However, the Oase individual does not share more alleles with later Europeans than with East Asians, suggesting that the Oase population did not contribute substantially to later humans in Europe.

    Six hundred and twenty-four Vibrio cholerae O1 strains, 623 serotype Ogawa and one serotype Inaba, isolated in Romania between 1977-95 were tested to detect all changing traits concerning serogroup, serotype, biotype, phage type and resistotype patterns and subsequently, the possible epidemiological relationship among these strains. Biotyping revealed one classical, 580 eltor strains and 43 intermediary variants. When tested with Mukerjee phages, 546 (87%) strains were sensitive and 78 (13%) resistant. One phage type (M4) dominated during 1977-90, two phage types (M4 and M5) exhibited the same high frequencies during 1991, a diversity of types occurred during 1993-4 whereas in 1995, two phage types (M4 and M5) showed similar distributions again. Five patterns of drug susceptibility were successively described during 1977-95. The most prominent changes in Vibrio cholerae O1 strains were noticed during 1993-4: the highest number of non-typable strains and intermediary variants, the widest spectrum of phage types and of multidrug resistance. In 1995, the strains reverted to the previous typable forms but a new drug resistance pattern was noticed. PMID:9825774

    An epidemiological and molecular study was conducted to investigate the occurrence and genetic diversity of Echinococcus granulosus isolates from adult sheep and cattle in Romania. Overall, 642 sheep (aged over 3 years) and 1878 cattle (aged over 5 years) from 16 counties were examined for hydatid cysts. Of them, 421 (65.6%) sheep and 754 (40.1%) cattle were found infected by cystic echinococcosis (CE). Germinal layers were collected from 98 individual cysts (one cyst per animal; 31 from sheep and 67 from cattle), DNA was extracted and two different mitochondrial DNA genes, namely cytochrome c oxidase subunits 1 (CO1) and 12S ribosomal DNA (12S rDNA) were used as genetic markers. The assessment of the genetic diversity of the Echinococcus strains showed the presence of the E. granulosus sensu stricto complex and disclosed an apparent dominance of the G1 genotype within the G1–G3 complex. Furthermore, several mitochondrial variants were identified for the G1 and G2 genotypes of E. granulosus s.s. complex. Overall, the findings were of epidemiological relevance and highlighted a high potential risk of zoonotic infection.

    Background: Aristolochic acid (AA) is a nephrotoxicant associated with AA nephropathy (AAN) and upper urothelial tract cancer (UUTC). Whole-genome sequences of 14 Romanian cases of renal cell carcinoma (RCC) recently exhibited mutational signatures consistent with AA exposure, although RCC had not been previously linked with AAN and AA exposure was previously reported only in localised rural areas. Methods: We performed mass spectrometric measurements of the aristolactam (AL) DNA adduct 7-(deoxyadenosin-N6-yl) aristolactam I (dA-AL-I) in nontumour renal tissues of the 14 Romanian RCC cases and 15 cases from 3 other countries. Results: We detected dA-AL-I in the 14 Romanian cases at levels ranging from 0.7 to 27 adducts per 108 DNA bases, in line with levels reported in Asian and Balkan populations exposed through herbal remedies or food contamination. The 15 cases from other countries were negative. Interpretation: Although the source of exposure is uncertain and likely different in AAN regions than elsewhere, our results demonstrate that AA exposure in Romania exists outside localised AAN regions and provide further evidence implicating AA in RCC.

    INTRODUCTION Wide-spread environmental contamination associated with historic mining in Europe has triggered social responses to improve related environmental legislation, the environmental assessment and management methods for the mining industry. Pollution by acid mine drainage (AMD) from ore and coal mining is the outstanding and most important source of mining-induced environmental pollution. Younger et al. (2002) estimates that watercourses polluted by coal mine drainage could be in the order of 2,000 to 3,000 km, and 1,000 to 1,500 km polluted by metal mine discharges for the EU 15 Member States (Younger et al. 2002). Significance of contamination risk posed by mining is also highlighted by mine accidents such as those in Baia Mare, Romania in 2002 and in Aznalcollar, Spain in 1999 (Jordan and D'Alessandro 2004). The new EU Mine Waste Directive (Directive 2006/21/EC) requires the risk-based inventory of abandoned mines in the EU. The cost-effective implementation of the inventory is especially demanding in countries with extensive historic mining and great number of abandoned mine sites, like Romania. The problem is further complicated in areas with trans-boundary effects. The objective of this investigation to carry out the risk-based contamination assessment of a mine site with possible trans-boundary effects in Romania. Assessment follows the source-pathway-receptor chain with a special attention to heavy metal leaching from waste dumps as sources and to transport modelling along surface water pathways. STUDY AREA In this paper the Baiut mine catchment located in the Gutai Mts., Romania, close to the Hungarian border is studied. The polymetallic deposites in the Tertiary Inner-Carpathian Volcanic Arc are exposed by a series of abandoned Zn and Pb mines first operated in the 14th century. Elevation in the high relief catchment ranges from 449m to 1044m. Geology is characterised by andesites hosting the ore deposits and paleogene sediments dominating at the

    In the present study, the measurements of radon were carried out using the LUK-VR system based on radon gas measurements with Lucas cells. The radium concentration in water was determined, with the same device, immediately after was established the radon equilibrium with radium. The results presented here are from a survey carried out in the N-W region of Transylvania (Romania) in which were investigated the radon concentrations in natural (spring, well and surface) and drinking (tap) waters. The results showed radon concentrations within the range of 0.4-187.3 Bq l(-1) with an average value of 15.9 Bq l(-1) whereas radium concentration varied between 0.05 and 0.825 Bq l(-1) with an average value of 0.087 Bq l(-1) for all types of water covered within this survey. The corresponding annual effective ingestion dose due to radon and radium from water was determined from drinking water used by the population inhabiting the area. PMID:25031036

    Biofouling occurs without exception in all water systems, with undesirable effects such as biocorrosion and deterioration of water quality. Drinking water associated biofilms represent a potential risk to human health by harbouring pathogenic or toxin-releasing microorganisms. This is the first study investigating the attached microbiota, with potential threat to human health, in a public water system in Romania. The presence and the seasonal variation of viable faecal indicators and opportunistic pathogens were investigated within naturally developed biofilms in a drinking water treatment plant. Bacterial frequencies were correlated with microbial loads in biofilms as well as with physical and chemical characteristics of biofilms and raw water. The biofilms assessed in the current study proved to be extremely active microbial consortia. High bacterial numbers were recovered by cultivation, including Pseudomonas aeruginosa, Escherichia coli, Aeromonas hydrophila, intestinal enterococci and Clostridium perfringens. There were no Legionella spp. detected in any biofilm sample. Emergence of opportunistic pathogens in biofilms was not significantly affected by the surface material, but by the treatment process. Implementation of a water safety plan encompassing measures to prevent microbial contamination and to control biofouling would be appropriate.

    The Romanian HIV epidemic started and evolved as a paediatric one, accounting for more than a quarter of the total European juvenile AIDS cases. In response to this major AIDS outbreak, emphasis was placed on the patient’s treatment, by implementation of a free, universal access program of Highly Active AntiRetroviral Therapy. This approach has been highly successful, and has greatly increased the rate of survival in infected children. Nevertheless, these children are now teenagers or young adults, representing a large cohort of “long term survivors”- a unique population that represent a great challenge for the public health system and for their integration in the civil society. As the number of HIV infected adults is increasing, new high-risk behaviour groups, as well as vulnerable populations (young people, people living in poverty, Rroma community) need to be reached in prevention programs. This article explores the impact of the socio-economic changes on the evolution of the HIV epidemic in Romania and speculates about the factors that might drive future increases in the incidence of HIV infections.

    During an entomological investigation carried out in Bucharest and surroundings in fall of 2012, 45 adult mosquitoes (38 females and 7 males) of Aedes albopictus were collected in a neighborhood from the southern area of the city. The morphological identification of the species was further confirmed by sequencing 2 mitochondrial DNA markers: the cytochrome c oxidase subunit I and NADH dehydrogenase subunit 5 genes. Aedes albopictus was collected again in 2013 in the same area from July until October. During late summer the species was found also in another location in the city, downtown Bucharest. Larvae were found in water barrels and other types of household containers, as well as in rain catch basins. In 2014, following a nuisance complaint of a Bucharest inhabitant, the entomological investigation found aggressive Ae. albopictus adults on his property that harbored many mosquito larvae in container-type breeding habitats. These findings are the 1st records of this invasive species and of its breeding population in Romania, and show maintenance of the species over 2 winter seasons. Surveillance of the species outside the area of the capital city was not performed, therefore it is not known whether Ae. albopictus has been introduced in other regions of the country. The presence of Ae. albopictus has been reported every year (2012-14) to competent public health authorities, stressing on the importance of surveillance and of implementation of control measures.

    Multimetric biotic indices increasingly are used to complement physicochemical data in assessments of stream quality. We initiated development of multimetric indices, based on fish communities, to assess biotic integrity of streams in two physiographic regions of central Romania. Unlike previous efforts to develop such indices for European streams, our metrics and scoring criteria were selected largely on the basis of empirical relations in the regions of interest. We categorised 54 fish species with respect to ten natural-history attributes, then used this information to compute 32 candidate metrics of five types (taxonomic, tolerance, abundance, reproductive, and feeding) for each of 35 sites. We assessed the utility of candidate metrics for detecting anthropogenic impact based on three criteria: (a) range of values taken, (b) relation to a site-quality index (SQI), which incorporated information on hydrologic alteration, channel alteration, land-use intensity, and water chemistry, and (c) metric redundancy. We chose seven metrics from each region to include in preliminary multimetric indices (PMIs). Both PMIs included taxonomic, tolerance, and feeding metrics, but only two metrics were common to both PMIs. Although we could not validate our PMIs, their strong association with the SQI in each region suggests that such indices would be valuable tools for assessing stream quality and could provide more comprehensive assessments than the traditional approaches based solely on water chemistry.

    This work focuses on the hydro-meteorological analysis for landslide triggering rainfall thresholds estimation in the Ialomita Subcarpathians. This specific area is a complex geological and geomorphic unit in Romania, affected by landslides that produce numerous damages to the infrastructure every few years (1997, 1998, 2005, 2006, 2010, 2012 and 2014). Semi-distributed ModClark hydrological model implemented in HEC HMS software that integrates radar rainfall data, was used to investigate hydrological conditions within the catchment responsible for the occurrence of landslides during the main rainfall events. Statistical analysis of the main hydro-meteorological variables during the landslide events that occurred between 2005 and 2014 was carried out in order to identify preliminary rainfall thresholds for landslides in the Ialomita Subcarpathians. Moreover, according to the environmental catchment characteristics, different hydrological behaviors could be identified based on the spatially distributed rainfall estimates from weather radar data. Two hydrological regimes in the catchments were distinguished: one dominated by direct flow that explains the landslides that occurred due to slope undercutting and one characterized by high soil water storage during prolonged rainfall and therefore where subsurface runoff is significant. The hydrological precipitation-discharge modelling of the catchment in the Ialomita Subcarpathians, in which landslides occurred, helped understanding the landslide triggering and as such can be of added value for landslide research.

    The paper presents the deuterium and oxygen 18 content from All precipitations events, which have occured over Cluj-Napoca, Romania from 2009 until 2012. Time series for δ{sup 2}H and δ{sup 18}O values point out both the seasonal variation that has increased amplitude reflecting the continental character of the local climate as well as dramatic variations of isotopic content of successive precipitation events, emphasizing the anomalous values. These fluctuations are the footprint of the variations and trends in climate events. Local Meteoric Water Line (LMWL), reflecting the δ{sup 2}H - δ{sup 18}O correlation, has the slop and the intercept slightly deviated from the GMWL, indicating that the dominant process affecting local precipitations are close to the equilibrium condition. LMWL has a slope smaller then that of the GMWL in the warm season due to lower humidity and a slope closest to the slop of GMWL in cold season with high humidity. The δ{sup 2}H and δ{sup 18}O values both for the precipitation events and monthly mean values are positively correlated with the temperature values with a very good correlation factor. The values of δ{sup 2}H and δ{sup 18}O are not correlated with amount of precipitation, the 'amount effect' of isotopic composition of precipitation is not observed for this site.

Uranium concentrations are largely determined by dissolution of limestones, although weathering of black shales represents an important additional source in some basins. In shield terrains the level of dissolved U is transport limited. Data from the Amazon indicate that floodplains do not represent a significant source of U in river waters. In addition, the authors have determined dissolved U levels in forty rivers from around the world and coupled these data with previous measurements to obtain an estimate for the global flux of dissolved U to the oceans. The average concentration of U in river waters is 1.3 nmol/kg, but this value is biased by very high levels observed in the Ganges-Brahmaputra and Yellow rivers. When these river systems are excluded from the budget, the global average falls to 0.78 nmol/kg. The global riverine U flux lies in the range of 3-6 [times] 10[sup 7] mol/yr. The major uncertainty that restricts the accuracy of this estimate (and that of all other dissolved riverine fluxes) is the difficulty in obtaining representative samples from rivers which show large seasonal and annual variations in runoff and dissolved load.

    Losses due to natural hazard events can be extraordinarily high and difficult to cope with. Therefore, there is considerable interest to estimate the potential impact of current and future extreme events at all scales in as much detail as possible. As hazards typically spread over wider areas, risk assessment must take into account interrelations between regions. Neglecting such interdependencies can lead to a severe underestimation of potential losses, especially for extreme events. This underestimation of extreme risk can lead to the failure of riskmanagement strategies when they are most needed, namely, in times of unprecedented events. In this article, we suggest a methodology to incorporate such interdependencies in risk via the use of copulas. We demonstrate that by coupling losses, dependencies can be incorporated in risk analysis, avoiding the underestimation of risk. Based on maximum discharge data of river basins and stream networks, we present and discuss different ways to couple loss distributions of basins while explicitly incorporating tail dependencies. We distinguish between coupling methods that require river structure data for the analysis and those that do not. For the later approach we propose a minimax algorithm to choose coupled basin pairs so that the underestimation of risk is avoided and the use of river structure data is not needed. The proposed methodology is especially useful for large-scale analysis and we motivate and apply our method using the case of Romania. The approach can be easily extended to other countries and natural hazards. PMID:26010101

    A model to simulate the time evolution of river delta formation process is presented. It is based on the continuity equation for water and sediment flow and a phenomenological sedimentation/erosion law. Different delta types are reproduced by using different parameters and erosion rules. The structures of the calculated patterns are analyzed in space and time and compared with real data patterns. Furthermore, our model is capable of simulating the rich dynamics related to the switching of the mouth of the river delta. The simulation results are then compared with geological records for the Mississippi River. PMID:17940031

    relationships were then determined parameters for river sub-basins and river reaches hydrometrically uncontrolled. Finally, floods from the closing station of Crişul Alb River Basin were simulated. This operation allowed the recalibration of the CONSUL Model parameters for the analyzed river basin. The results of the simulation with the CONSUL Model in the Crişul Alb River Basin showed that the model gives the best results, in particular in the case of floods generated by precipitation evenly distributed in space. Deviations of flow hydrographs simulated by CONSUL Model and observed are due to both model errors and insufficient meteorological and hydrological data. The main error is caused by the uncertainty related to the average precipitation computed values on each basin and its variable spatial and temporal distribution. The paper presents the results obtained within the CLIMHYDEX project ("Changes in climate extremes and associated impact in hydrological events in Romania", cod PNII-ID-2011-2-0073, http://climhydex.meteoromania.ro), project in which to estimate the impact of climate change and variability upon the maximum discharges from Crişul Alb River Basin will be achieved long-term simulations using hydrological model CONSUL.

    The Nuclear Research Reactor VVR-S (RR-VVR-S) located in Magurele-Bucharest, Romania, was designed for research and radioisotope production. It was commissioned in 1957 and operated without any event or accident for forty years until shut down in 1997. In 2002, by government decree, it was permanently shutdown for decommissioning. The National Institute of Physics and Nuclear Engineering (IFIN-HH) is responsible for decommissioning the RR-VVR-S, the first nuclear decommissioning project in Romania. In this context, IFIN-HH prepared and obtained approval from the Romanian Nuclear Regulatory Body for the Decommissioning Plan. One of the most important aspects for decommissioning the RR-VVR-S is solving the issue of the fresh and spent nuclear fuel (SNF) stored on site in wet storage pools. In the framework of the Russian Research Reactor Fuel Return Program (RRRFR), managed by the U.S. Department of Energy and in cooperation with the International Atomic Energy Agency and the Rosatom State Corporation, Romania repatriated all fresh HEU fuel to the Russian Federation in 2003 and the HEU SNF will be repatriated to Russia in 2009. With the experience and lessons learned from this action and with the financial support of the Romanian Government it will be possible for Romania to also repatriate the LEU SNF to the Russian Federation before starting the dismantling and decontamination of the nuclear facility.

    The main objective of this paper is to describe the late Holocene behaviour of rivers using an interdisciplinary approach combining fluvial geomorphology and subfossil trunk dendrochronology. The subfossil wood material collected along the rivers was investigated for dendrometric and dendrochronologic parameters. The research methods in these fields helped us to understand the effect of the fluvial environment on riparian trees and their records and helped in reconstructing the riparian palaeoenvironment. The study area consists of two rivers with different typologies but comparable sizes: the Moldova River, which features a braided to wandering channel in its lower reach, and the Siret River, which features a sinuous-meandering channel. Along the 100-km-long floodplain of the former and the 144-km-long floodplain of the latter, we found and sampled 77 subfossil trunks, of which 26 were subjected to 14C dating. The resulting data consist of floodplain facies mapping data, electric resistivity measurements, absolute dates, and dendrometric and dendrochronologic data. The results indicate that during a 100-year period, the two rivers were sensitive to climate change and anthropogenic effects, particularly a narrowing of the active channel by 76% in the braided channel and 38% in the sinuous-meandering channel. During the past 3300-3000 YBP, the Moldova River maintained its braided style, whereas the sinuous-meandering style has been characteristic of the Siret River for the previous 6800-4600 YBP. The two distinct fluvial environments are recorded in the dendrometric structure of the trunks buried in the channel-fill sediments. The braided fluvial environment was more effective in uprooting riparian trees and incorporating them in the floodplain deposits, whereas the sinuous-meandering style of stream effectively buried tree trunks in lateral accretion lobes. Absolute and dendrochronologic dating allowed for the reconstruction of timelines of the felling of the trees

    The quality of water is of paramount importance in the management of water resources - including marine waters. A quantitative knowledge of water quality and the factors governing it is required to formulate and implement strategies requiring an inter-disciplinary approach. The overall purpose of this conference was to bring together the latest work on water quality aspects of river basin management. These proceedings are structured on the basis of five themes: problems in international river basins; the contribution of river systems to estuarial and marine pollution; the setting of standards; monitoring; and practical water quality management including use of mathematical models. They are followed by papers from the workshop on advances in the application of mathematical modelling to water quality management, which represent some of the current thinking on the problems and concepts of river basin management.

  9. Seismic investigations of the Earth's lithosphere and asthenosphere in two unique convergent margin settings: The Carpathians, Romania, and U.S. Cordillera, Idaho-Oregon

    NASA Astrophysics Data System (ADS)

    Stanciu, Adrian Christian

    Proposed mechanisms for the unusual seismicity ~100 km southeast of the contact between the Transylvanian Basin and the Eastern Carpathians in Romania have included tearing and rollback of a subducted slab of oceanic lithosphere and gravitational instability and delamination of continental lithosphere. We examined the upper mantle fabrics using shear wave splitting of SK(K)S phases recorded at four broadband seismic stations in the Transylvanian Basin. Our results indicate a regional NW-SE splitting trend, with measurements that reflect an abrupt change from this regional flow field in the vicinity of the Vrancea body to a NE-SW trend that is consistent with redirection of mantle flow. Crustal thickness measurements show 28-30 km in the western part of the Transylvanian Basin, 34-39 km at the contact with the Eastern Carpathians, and 40-45 km further east. These results, along with previous estimates, constrain the locus of the inferred Miocene suture between the southeastern-most portion of the Tisza-Dacia terrane and the East European Platform. The second convergent margin system represented here is in the North American Cordillera in Idaho and Oregon, where subduction and accretion of exotic terranes have modified the western margin of North America. We used teleseismic receiver functions from 85 broadband stations to analyze the geometry of the Salmon River suture zone, the western Idaho shear zone, and the Grouse Creek-Farmington zone boundary. Results show a clear break in crustal thickness from ~28 km beneath the accreted terranes to 36 km east of the surface expression of the WISZ. A strong mid-crustal converter at ~20 km depth is consistent with tectonic wedging during accretion of the Blue Mountains terranes. An eastern Moho offset of ~6 km is consistent with the Archean Grouse Creek-Farmington zone boundary. We used deep converted phases generated beneath the study area to image the mantle transition zone. We observe a continuous high amplitude P410s

    In the year 2006, the first experience with the NO-TILLAGE system for sunflower crops was organized in Romania, using the Pioneer PR64E83 sunflower hybrid resistant to the tribenuron-methyl herbicide. The experience took place in the Danube river flood plain, on an alluvial soil with a content between 3.1-4.5% and a content of clay of 34-40%. In the conventional system, in the fall of the year 2005, autumn ploughing was carried out, along with harrowing, and in spring the land was tilled two more times, using both the disk and the harrow. Before sowing, the land was prepared by using the combiner-machine. After the sunflower sprouted, three-time mechanical hoeing between the rows, as well as three-time manual hoeing on the sunflower row were performed. In the no-tillage system, no autumn ploughing, nor any other soil work were performed, and the sunflower was sowed directly, by using the Gaspardo seeder. Before sowing, the soil was covered in proportion of 70% by species of weeds of the Cirsum, Sonchus and Polygonum amphibium type. To destroy these species of weeds, 3 days before sowing, the soil was treated with the Roundup herbicide in a dose of 7 litres/ha. After the sunflower sprouted, when the plants had 4-5 leaves, the following sulphonylurea herbicides were applied post-emergently. (1) Express 50SG--which contains tribenuron-methyl (2) Granstar 75DF--which contains 75% tribenuron-methyl (3) Titus 25DF--which contains 25% rimsulfuron (4) Mistral--which contains 40 g/L nicosulfuron (5) Lintur 70WG--which contains 4.1% triasulfuron + 65.9% dicamba (6) Peak 75WG--which contains 75% prosulfuron The Express 50SG and Granstar 75DF herbicides were selective for the sunflower hybrid PR64E83, and the other herbicides although belonging o the same sulphonylurea group, they proved to have a very phytotoxic effect upon the sunflower crop. In the report, selectivity is presented depending on the dose of herbicide, weed control and sunflower production.

    2011-12-01

    The description of fluvial form has evolved from anecdotal descriptions to artistic renderings to 2D plots of cross section or longitudinal profiles and more recently 3D digital models. Synthetic river valleys, artificial 3D topographic models of river topography, have a plethora of potential applications in fluvial geomorphology, and the earth sciences in general, as well as in computer science and ecology. Synthetic river channels have existed implicitly since approximately the 1970s and can be simulated from a variety of approaches spanning the artistic and numerical. An objective method of synthesizing 3D stream topography based on reach scale attributes would be valuable for sizing 3D flumes in the physical and numerical realms, as initial input topography for morphodynamic models, stream restoration design, historical reconstruction, and mechanistic testing of interactions of channel geometric elements. Quite simply - simulation of synthetic channel geometry of prescribed conditions can allow systematic evaluation of the dominant relationships between river flow and geometry. A new model, the control curve method, is presented that uses hierarchically scaled parametric curves in over-lapping 2D planes to create synthetic river valleys. The approach is able to simulate 3D stream geometry from paired 2D descriptions and can allow experimental insight into form-process relationships in addition to visualizing past measurements of channel form that are limited to two dimension descriptions. Results are presented that illustrate the models ability to simulate fluvial topography representative of real world rivers as well as how channel geometric elements can be adjusted. The testing of synthetic river valleys would open up a wealth of knowledge as to why some 3D attributes of river channels are more prevalent than others as well as bridging the gap between the 2D descriptions that have dominated fluvial geomorphology the past century and modern, more complete, 3D

    2015-04-01

    The hydromorphic regimes that underpinned Old World river-based civilizations are reviewed in light of recent research. Notable Holocene climatic changes varied from region to region, whilst the dynamics of floodplain environments were equally diverse, with river channel changes significantly affecting human settlement. There were longer-term trends in Holocene hydroclimate and multi-centennial length 'flood-rich' and 'flood-poor' episodes. These impacted on five identified flooding and settlement scenarios: (i) alluvial fans and aprons; (ii) laterally mobile rivers; (iii) rivers with well-developed levees and flood basins; (iv) river systems characterised by avulsions and floodouts; and (v) large river-fed wetlands. This gave a range of changes that were either more or less regular or incremental from year-to-year (and thus potentially manageable) or catastrophic. The latter might be sudden during a flood event or a few seasons (acute), or over longer periods extending over many decades or even centuries (chronic). The geomorphic and environmental impacts of these events on riparian societies were very often irreversible. Contrasts are made between allogenic and autogenic mechanism for imposing environmental stress on riverine communities and a distinction is made between channel avulsion and contraction responses. Floods, droughts and river channel changes can precondition as well as trigger environmental crises and societal collapse. The Nile system currently offers the best set of independently dated Holocene fluvial and archaeological records, and the contrasted effects of changing hydromorphological regimes on floodwater farming are examined. The persistence of civilizations depended essentially on the societies that maintained them, but they were also understandably resilient in some environments (Pharaonic Egypt in the Egyptian Nile), appear to have had more limited windows of opportunity in others (the Kerma Kingdom in the Nubian Nile), or required

    The Connecticut River basin possesses some characteristics that make it unique for studying hydrologic issues that transcend scale. The watershed was first dramatically altered through natural processes (glaciation) and then heavily impacted by human stresses (dams, deforestation, acid precipitation/deposition), only to exhibit recent decades of return to a more natural state (reforestation, land conservation, stream restoration, pollution abatement, and dam removal). The watershed is sufficiently north to be classified as a cold region. More specifically to hydrology, the watershed exhibits the spectrum of flooding problems: ice dams, convective storms, hurricanes, rain on melting snow, and low pressure systems. The 28,000 square kilometer Connecticut River Watershed covers one third of the states of New Hampshire, Vermont, Massachusetts, and Connecticut. The >640-km long rivers' headwaters start on the Canadian border at the Fourth Connecticut Lake, and flows southward to discharge in Long Island sound. The lower 100 km of river are tidally influenced. The Connecticut River is responsible for 70 % of the freshwater inflow to Long Island Sound. The Connecticut River is a sixth order stream that exhibits a dendritic pattern in an elongated scheme. This setting therefore affords many first and second order streams in almost parallel fashion, flowing west or east towards the central Connecticut River spine. There are 38 major tributaries to the mainstem Connecticut River, and 26 of these tributaries drain greater than 250 square kilometers. There is in excess of 30,000 km of perennially flowing stream length in the watershed. For more information, see: http://www.unh.edu/erg/connho/

  15. Plants accumulating heavy metals in the Danube River wetlands

    PubMed Central

    2013-01-01

    Background We present herein our results regarding the accumulation of four heavy metals (copper, cadmium, lead, and zinc) in four aquatic species plants (Ceratophyllum demersum, Potamogeton pectinatus, Potamogeton lucens, Potamogeton perfoliatus) collected from the Danube River, South-Western part of Romania and their possible use as indicators of aquatic ecosystems pollution with heavy metals. Methods Elements concentration from the vegetal material was determined through Inductively Coupled Plasma – Mass Spectrometry. Results The species were chosen based on their previous use as bioindicators in aquatic ecosystems and due to the fact they are one of the most frequent aquatic plant species of the Danube River ecosystems within the Iron Gates Natural Park. Highest amounts are recorded for Ceratophyllum demersum (3.52 μg/g for Cd; 22.71 μg/g for Cu; 20.06 μg/g for Pb; 104.23 μg/g for Zn). Among the Potamogeton species, the highest amounts of heavy metals are recorded in Potamogeton perfoliatus (1.88 μg/g for Cd; 13.14 μg/g for Cu; 13.32 μg/g for Pb; 57.96 μg/g for Zn). The sequence for the bioconcentration factors (BCFs) calculated in order to describe the accumulation of the four metals is Cd >> Zn > Pb > Cu. Increase of the zinc concentration determines an increase of the cadmium concentration (Spearman rho=0.40, p=0.02). Conclusions Despite the low ambiental levels of heavy metals, the four aquatic plants have the ability to accumulate significant amounts, which make them useful as biological indicators. BCF value for Ceratophyllum demersum indicated this species as a cadmium hyperaccumulator. PMID:24359799

    The members of the Anopheles maculipennis complex have been incriminated for the transmission of the malaria in Europe, which was endemic until the middle of the century. The global warming and the intensification of the intercontinental travel constitute a risk of the re-emergence of the malaria in Europe, given the presence of the Anopheles vectors. The study has attempted the identification by using the PCR (Polymerase Chain Reaction) of the members of the Anopheles maculipennis complex from the North-eastern area of Romania from the city of Iaşi. In total there have been identified by using the PCR amplifying the ITS2 sequence of the ribosomal DNA, 217 specimens belonging to the complex of A. maculipennis among which: 58 A. atroparvus, 18 A. melanoon, 2 A. labranchiae, 52 A. maculipennis and 87 A. messeae. The ITS2 sequences of the ribosomal DNA have been compared to those of the species belonging to the A. maculipennis available in GenBank. The Species A. labranchiae is reported for the first time in Romania, being identified in the larval stage IV. The adaptation of a new species to the climatic conditions present in the North-eastern Romania, confirms the phenomenon of global warming and also the intensification of the travelling. As a result of the analysis of the A. labranchiae sequence, this one corresponds to the extent of 96% to the species from Italy, registered in GenBank, given the fact that a high number of the inhabitants of the municipality of Iaşi are working in this country.

    Various methods exist in analyzing spatial landslide susceptibility and classing the results in susceptibility classes. The prediction of spatial landslide distribution can be performed by using a variety of methods based on GIS techniques. The two very common methods of a heuristic assessment and a logistic regression model are employed in this study in order to compare their performance in predicting the spatial distribution of previously mapped landslides for a study area located in Maramureš County, in Northwestern Romania. The first model determines a susceptibility index by combining the heuristic approach with GIS techniques of spatial data analysis. The criteria used for quantifying each susceptibility factor and the expression used to determine the susceptibility index are taken from the Romanian legislation (Governmental Decision 447/2003). This procedure is followed in any Romanian state-ordered study which relies on financial support. The logistic regression model predicts the spatial distribution of landslides by statistically calculating regressive coefficients which describe the dependency of previously mapped landslides on different factors. The identified shallow landslides correspond generally to Pannonian marl and Quaternary contractile clay deposits. The study region is located in the Northwestern part of Romania, including the Baia Mare municipality, the capital of Maramureš County. The study focuses on the former piedmontal region situated to the south of the volcanic mountains Gutâi, in the Baia Mare Depression, where most of the landslide activity has been recorded. In addition, a narrow sector of the volcanic mountains which borders the city of Baia Mare to the north has also been included to test the accuracy of the models in different lithologic units. The results of both models indicate a general medium landslide susceptibility of the study area. The more detailed differences will be discussed with respect to the advantages and

Here three EURO-CORDEX regional climate models (RCMs) ensemble (scenario RCP4.5) are analysed and inter-compared: DMI-HIRHAM5, KNMI-RACMO2.2 and MPI-REMO. Compared to previous studies, when the RCM validation regarding the Romanian climate has mainly been made on mean state and at station scale, a more quantitative approach of precipitation extremes is proposed. In this respect, to have a more reliable comparison with observation, a high resolution daily precipitation gridded data set was used as observational reference (CLIMHYDEX project). The comparison between the RCM outputs and observed grid point values has been made by calculating three extremes precipitation indices, recommended by the Expert Team on Climate Change Detection Indices (ETCCDI), for the 1976-2005 period: R10MM, annual count of days when precipitation ≥10mm; RX5DAY, annual maximum 5-day precipitation and R95P%, precipitation fraction of annual total precipitation due to daily precipitation > 95th percentile. The RCMs capability to reproduce the mean state for these variables, as well as the main modes of their spatial variability (given by the first three EOF patterns), are analysed. The investigation confirms the ability of RCMs to simulate the main features of the precipitation extreme variability over Romania, but some deficiencies in reproducing of their regional characteristics were found (for example, overestimation of the mea state, especially over the extra Carpathian regions). This work has been realised within the research project "Changes in climate extremes and associated impact in hydrological events in Romania" (CLIMHYDEX), code PN II-ID-2011-2-0073, financed by the Romanian

    The members of the Anopheles maculipennis complex have been incriminated for the transmission of the malaria in Europe, which was endemic until the middle of the century. The global warming and the intensification of the intercontinental travel constitute a risk of the re-emergence of the malaria in Europe, given the presence of the Anopheles vectors. The study has attempted the identification by using the PCR (Polymerase Chain Reaction) of the members of the Anopheles maculipennis complex from the North-eastern area of Romania from the city of Iaşi. In total there have been identified by using the PCR amplifying the ITS2 sequence of the ribosomal DNA, 217 specimens belonging to the complex of A. maculipennis among which: 58 A. atroparvus, 18 A. melanoon, 2 A. labranchiae, 52 A. maculipennis and 87 A. messeae. The ITS2 sequences of the ribosomal DNA have been compared to those of the species belonging to the A. maculipennis available in GenBank. The Species A. labranchiae is reported for the first time in Romania, being identified in the larval stage IV. The adaptation of a new species to the climatic conditions present in the North-eastern Romania, confirms the phenomenon of global warming and also the intensification of the travelling. As a result of the analysis of the A. labranchiae sequence, this one corresponds to the extent of 96% to the species from Italy, registered in GenBank, given the fact that a high number of the inhabitants of the municipality of Iaşi are working in this country.

  20. The present state of knowledge on the high-technology elements in porphyry copper deposit from Romania

    Porphyry copper deposits are the most important source of Cu in the world, but also a source of Mo, Au, Ag and Sn. Some "high-technology elements" (HTE), such as Re, In, W, Te and Se can reach economically-interesting concentrations in this type of deposits. Elevated platinum group elements (Pd and Pt) contents have been reported from several porphyry copper deposits from Balkan Peninsula and Pacific area. In Romania, numerous porphyry copper deposits occur in Banat (Southern Carpathians) and in Apuseni Mountains related to Alpine orogenesis. In Banat, they are classified as Cu-Mo type (Moldova Nouă, Sasca, Şopot, Bozovici, Teregova-Lăpuşnicel) [1] being associated with Laramian granodiorite/monzodiorite bodies of calc-alkaline affinity. The porphyry copper deposits from Apuseni Mountains are hosted mainly by microdiorite subvolcanic bodies and andesites of the Miocene calc-alkaline magmatism and can be divided in three types: Cu-Mo (Au) type (Deva, Roşia Poieni), Cu-Au type (Valea Morii, Bolcana, Rovina, Voia, Tălagiu, Larga, Trâmpoiele, Valea Tisei, Tarniţa) and Au-Cu porphyry (Colnic, Cireşata)[1,3]. The data on HTE of the porphyry-type deposits in Romania are scarce and they come only from a few deposits: Moldova Nouă, Valea Morii, Deva, Bucium-Tarniţa and Rovina [2]. The published contents of HTE in bulk rocks are generally low, but higher values were reported from Cu concentrates (e.g., 500 ppm Se at Deva, 500 ppm Te at Bucium-Tarniţa). There are no data on the platinum group elements contents. The presence of minerals of HTE in some porphyry copper deposits from Romania (e.g., germanium minerals at Bucium-Tarniţa, Roşia Poieni and Rovina) could be an indicator of the enrichment of such elements in the host intrusions. Considering the policy of the European Community towards the identification of new resources of HTE, more systematic investigations of these elements in the porphyry copper deposits of Romania is necessary.

    The ΣΣ intermediate-energy reference spectrum irradiation facility, operated until 1998 at the VVR-S Reactor from Bucharest, was put into operation at the Romania TRIGA Reactor. This paper presents the experimental devices developed for the ΣΣ system operating at the Steady State Reactor (SSR)-TRIGA core, including the monitoring system, and preliminary neutron characterization results. These results show that the spectrum characteristics are slowly deviating from those for the recommended ΣΣ spectrum. The high-energy neutron tail is slowly increasing, compared with the recommended ΣΣ spectrum and other similar facilities.

    This study shows the present environmental quality of superficial sediments within the aquatorium of an industrial harbor. These results help better understand the correlation between historical pollution and present environmental state of the harbor sediments and related environmental hazards in case of dredging. The study area is the Port of Midia, situated in Romania, western Black Sea coast. The port is located at the boundary between the Danube Delta coast (widest nature protected biosphere reserve in the EU) in the north - and the almost entirely human controlled coast - starting south of the port. Midia Harbor was first built in 1942, expanded during the late 1970`s, and currently operates as an oil and general merchandise terminal. This port receives a double impact of waters: brackish Black Sea waters, as well as Danube fresh waters arriving into the aquatorium through the inshore Danube - Black Sea Canal Lock. To understand the environmental status of the port aquatorium one sampling campaign was performed during August 2011. Samples were collected within the aquatorium and in in the surrounding area outside the harbor. For a better correlation with the particularities related to the transitions in water salinity, the aquatorium was divided into five sectors with specific characteristics: Cargo Terminal Area, Oil Terminal Enclosure Area, Ships Transit Area, Waste Oil Buffer Area and Marine Area. The following analyses were performed on water and sediment samples: physical and chemical characteristics of the waters (dissolved oxygen, temperature, electrical conductivity, total dissolved salts, pH, redox potential, nitrates, nitrites, phosphates, sulphates, heavy metals), bulk sediments (particle size, grain size distribution, mineralogy, organic matter and carbonates content, heavy minerals load, organic compounds) and microbiological and ecotoxicological assays. The grain size analysis reveals the prevalence of very fine-silt and silty-clay fractions, and

  4. Geospatial and In-Situ Monitoring Data for Seismic Hazard Assessment in Vrancea Area, Romania

    Zoran, Maria

    Seismic hazard for almost half of the Romanian territory is determined by the Vrancea ac-tive seismic region, placed beneath the southern Carpathian Arc in Romania at conjunction of four tectonic blocks, which lie on the edge of the Eurasian plate. Vrancea zone is considered one of the most seismically active area in Europe, being characterized by strong intermediate depth seismicity in a very limited and well defined hypocentral region.Space-time anomalies of Earth's emitted radiation (radon in underground water and soil , thermal infrared in spec-tral range measured from satellite months to weeks before the occurrence of earthquakes etc.), ionospheric and electromagnetic anomalies have been interpreted, by several authors, as pre-seismic signals.Satellite remote sensing provides a systematic, synoptic framework for advancing scientific knowledge of the Earth complex system of geophysical phenomena which often lead to seismic hazards. Space-based geodetic measurements of the solid Earth with the Global Positioning System, combined with ground-based seismological measurements and satellite re-mote sensing information are yielding the principal data for modeling lithospheric processes and for accurately estimating the distribution of potentially damaging strong ground motions which is critical for earthquake engineering applications. Moreover, integrated with interfero-metric synthetic aperture radar, these measurements provide spatially continuous observations of deformation with sub-centimeter accuracy. Seismic and in situ monitoring, geodetic mea-surements, high-resolution digital elevation models (e.g. from InSAR, IKONOS and digital photogrammetry) and imaging spectroscopy (e.g. using ASTER, MODIS and Hyperion) are contributing significantly to seismic hazard risk assessment by revealing new insights in the understanding of the kinematics and dynamics of the complex plate boundary system and long-term deformation in relation with earthquake activity.

    The present paper examines hydroclimatic dynamics in southwestern Romania drylands, which is one of the country's most heavily affected regions by climate change. The analysis focuses on two of the region's representative catchments (Drincea and Desnatui), covers the past five decades (1961-2009), and is based on climate data (mean monthly and annual climatic water balance values - CWB, expressed in mm) and hydrological data (mean monthly and annual streamflow rate values - SFR, expressed in m3/s). The data were provided by five regional weather stations, i.e., by five gauging stations located within the two catchments. The analysis was conducted on three temporal scales (annual, seasonal and monthly), and used statistical methods, such as Mann-Kendall test/Sen's slope method for trend analysis, and Spearman/Student test for the statistical association between climatic and hydrological parameters. The results indicated an overall increase in climatic water deficit, with direct effects on streamflow reduction. Statistically significant trends (climatic water deficit increase and streamflow decrease) were identified especially in spring (with maximum rate values of (-1.66 mm/yr)/(-81.3 mm/49 yrs), for the CWB, and (-0.02 m3/s/yr)/(-0.9 m3/s/49 yrs), for the SFR). In some cases (mainly in the autumn months) it was found that, while climatic water deficit has decreased, the streamflow rate has increased. Statistical correlations revealed the relationship between the considered hydroclimatic parameters, with a particularly high statistical significance in spring and summer. Weak and inverse correlations between climatic and hydrological parameters can be explained by the role of other factors controlling the streamflow, both natural (soil and lithology) and anthropogenic (wetland drainage, water body conversion, dam and reservoirs building).

  6. Slow geomorphologic evolution of rock glaciers in marginal periglacial environment of Southern Carpathians (Romania)

    The development of remote sensing techniques in the last several decades now permits surveying areas that are difficult to access and allows capturing geomorphological processes that operate at low deformation rates. In marginal periglacial environments, where the kinematics of the rock glaciers are defined by slow flow, specific remote sensing techniques (e.g., optical image cross-correlation techniques or multitemporal interferometry) are preferred because they are capable of providing ground displacement accuracies on the order of a few mm. Recent multi-temporal image analysis of high-resolution optical and radar satellite imagery of the Retezat Mountains (in the southern Carpathian Mountains of Romania) rock glaciers revealed very low rates of deformation and confirmed that active rock glaciers still exist here. These findings were supported by geophysical investigations (electrical resistivity tomography and ground penetrating radar) and thermal monitoring, which confirmed the patchy distribution of permafrost within the investigated rock glaciers. Given the high depth of the active layer (between 5 and 10 m) and the limited thickness of the ground ice bodies, the permafrost in the Retezat Mountains was assumed to exist in marginal conditions. The sporadic permafrost from the alpine zone of the southern Carpathians is extremely sensitive to environmental changes and responds directly to air temperature fluctuations. As an example, geophysical investigations between 2007 and 2014 revealed significant ground ice disappearance from one of the studied rock glaciers (i.e., Pietrele) as a result of rising air temperature. Optical satellite data revealed that the disappearance of ground ice led to accelerated movement of this rock glacier after 2007. The variability of horizontal movement is strongly controlled by the ground thermal regime. The results confirm the hypothesis that permafrost is not in equilibrium with the present-day climate in the Romanian

    In this nested case-control study, we investigated the risk factors for methemoglobinemia (MHG) in 71 children in the Transylvania region of Romania. This study was unique in that the exposures for cases and controls were calculated as continuous values and were reported in milligrams per kilogram per day of nitrate/nitrite based on careful dietary reconstruction and environmental sampling. This procedure allowed us to compare point estimates of nitrate/nitrite exposure with other continuous, categoric, and ranked risk factors such as the presence or absence of diarrheal disease, reported severity of diarrheal disease, the use of vitamin supplements, the presence, absence, and/or duration of breast-feeding, and whether or not first-generation relatives experienced MHG. Analysis of these factors and exposure levels using both univariate and multivariate whole-model tests was performed to understand the relative significance of risk factors at varying levels of exposure to the development of MHG. Univariate and multifactorial analysis of risk factors for MHG underscored that, for this population, MHG is most strongly associated with nitrate/nitrite exposure through the dietary route (p = 0.0318), via feeding of formula and tea made with water containing high levels of nitrates, and that breast-feeding protects infants younger than 6 months of age (p = 0.0244). Our findings also raise questions about the role of diarrheal disease in the development of MHG, as likelihood ratios (likelihood 4.323, p = 0.0376) and multifactorial analysis indicated a significant role for diarrheal disease for some individuals.

    This paper address a regional scale analysis of the rainfall induced landslides for 2014 storm events based on detailed hydro-meteorological data set in the Ialomita Subcarpathians. This area is located in the western part of the Curvature Subcarpathians, a complex geological and geomorphic unit in Romania. The high temporal frequency of landslide events from the last decades (1997, 1998, 2005, 2006, 2010, 2012 and 2014) leads us to consider that these processes play a major role in the evolution of this area's landscape where the most frequent landforms are: slumps, earth flows, mudflows and complex movements. The rainy period between April-August 2014 induced numerous flash-floods and landslides in this specific area that resulted to severe economic losses estimated to €8 million in Dambovita County. Spatially distributed rainfall during the main storm events estimated from adjusted radar-based precipitation was used to analysis the hydro-meteorological conditions that triggered or not landslides in the Ialomita Subcarpathians. Hydrological preconditions were assessed by hourly in situ soil moisture measurements at local scale and hydrological modelling at regional scale. ModClark semi distributed model implemented in HEC HMS software that integrates radar data was used to analysis catchment response to the main rainfall event that triggered the landslides in 2014. Analysis between rainfall, soil moisture conditions and direct runoff was performed for identifying the contribution of the hydro-meteorologic conditions to landsliding process in the Ialomita Subcarpathians. A detailed landslide inventory based on field mapping and visual interpretation of satellite and aerial images was completed with information from local authorities and mass media. Despite the limited number of landslide events, this study allows a detailed insight of understanding the influence of rainfall in landslide occurrence in this specific area with the aim of improving landslide

    Niphargus is a speciose amphipod genus found in groundwater habitats across Europe. Three Niphargus species living in the sulphidic Frasassi caves in Italy harbour sulphur-oxidizing Thiothrix bacterial ectosymbionts. These three species are distantly related, implying that the ability to form ectosymbioses with Thiothrix may be common among Niphargus. Therefore, Niphargus–Thiothrix associations may also be found in sulphidic aquifers other than Frasassi. In this study, we examined this possibility by analysing niphargids of the genera Niphargus and Pontoniphargus collected from the partly sulphidic aquifers of the Southern Dobrogea region of Romania, which are accessible through springs, wells and Movile Cave. Molecular and morphological analyses revealed seven niphargid species in this region. Five of these species occurred occasionally or exclusively in sulphidic locations, whereas the remaining two were restricted to nonsulphidic areas. Thiothrix were detected by PCR on all seven Dobrogean niphargid species and observed using microscopy to be predominantly attached to their hosts' appendages. 16S rRNA gene sequences of the Thiothrix epibionts fell into two main clades, one of which (herein named T4) occurred solely on niphargids collected in sulphidic locations. The other Thiothrix clade was present on niphargids from both sulphidic and nonsulphidic areas and indistinguishable from the T3 ectosymbiont clade previously identified on Frasassi-dwelling Niphargus. Although niphargids from Frasassi and Southern Dobrogea are not closely related, the patterns of their association with Thiothrix are remarkably alike. The finding of similar Niphargus–Thiothrix associations in aquifers located 1200 km apart suggests that they may be widespread in European groundwater ecosystems. PMID:24044653

    Land surface temperature is one of the most important parameters related to global warming. It depends mainly on soil type, discontinuous vegetation cover, or lack of precipitation. The main purpose of this paper is to investigate the relationship between high LST, synoptic conditions and air masses trajectories, vegetation cover, and soil type in one of the driest region in Romania. In order to calculate the land surface temperature and normalized difference vegetation index, five satellite images of LANDSAT missions 5 and 7, covering a period of 26 years (1986-2011), were selected, all of them collected in the month of June. The areas with low vegetation density were derived from normalized difference vegetation index, while soil types have been extracted from Corine Land Cover database. HYSPLIT application was employed to identify the air masses origin based on their backward trajectories for each of the five study cases. Pearson, logarithmic, and quadratic correlations were used to detect the relationships between land surface temperature and observed ground temperatures, as well as between land surface temperature and normalized difference vegetation index. The most important findings are: strong correlation between land surface temperature derived from satellite images and maximum ground temperature recorded in a weather station located in the area, as well as between areas with land surface temperature equal to or higher than 40.0 °C and those with lack of vegetation; the sandy soils are the most prone to high land surface temperature and lack of vegetation, followed by the chernozems and brown soils; extremely severe drought events may occur in the region.

    Clouds play a key role in climate and weather forecasting. The observations of clouds and cloud cover at regional scale are very important in the study of clouds' radiative forcing, and consequently, in changing the radiative budget in the climatic system. This paper is focused on the analysis of spatial and temporal distribution of clouds and cloud cover. These observational data can be used in regional climate models. Synoptic surface cloud observations from 14 stations are used to examine the variability of the cloud cover in 2006 over Moldova, which is the extra Carpathian area of Romania. The hourly data of the total cloud cover and partial cloud ceiling were processed and statistically analyzed. The observational database was completed using a simple algorithm that improved the middle cloudiness environment by more than 39% and the high clouds environment by 100%, compared to the initial data. Trends in total and low cloud cover were investigated in detail by examining changes in the frequency of appearance. The significant underestimation for the middle and high clouds was obvious for low cloudiness values of 6, 7 and 8 oktas, and it has reduced the average cloud cover up to 4.5% and the top up to 15.4%. Seasonal analysis performed in January and July 2006 showed that the low cloud cover was 50% higher in winter as compared to the warm season. The presence of the middle cloud cover was constant during the two seasons (generally between 60-70%), while the high cloudiness dominated during the summer months. The investigations of smaller regions and interannual variability are important, although the real fluctuations in cloud cover are relatively large in such instances. As such, a study of the fluctuations in cloud cover will be necessary in the future.

    This study focuses on future forest cover change in Buzau Subcarpathians, a landslide prone region in Romania. Past and current trends suggest that the area might expect a future increase in deforestation. We developed spatially explicit scenarios until 2040 to analyze the spatial pattern of future forest cover change and potential changes to landslide risk. First, we generated transition probability maps using the weights of evidence method, followed by a cellular automata allocation model. We performed expert interviews, to develop two future forest management scenarios. The Alternative scenario (ALT) was defined by 67% more deforestation than the Business as Usual scenario (BAU). We integrated the simulated scenarios with a landslide susceptibility map. In both scenarios, most of deforestation was projected in areas where landslides are less likely to occur. Still, 483 (ALT) and 276 (BAU) ha of deforestation were projected on areas with a high-landslide occurrence likelihood. Thus, deforestation could lead to a local-scale increase in landslide risk, in particular near or adjacent to forestry roads. The parallel process of near 10% forest expansion until 2040 was projected to occur mostly on areas with high-landslide susceptibility. On a regional scale, forest expansion could so result in improved slope stability. We modeled two additional scenarios with an implemented landslide risk policy, excluding high-risk zones. The reduction of deforestation on high-risk areas was achieved without a drastic decrease in the accessibility of the areas. Together with forest expansion, it could therefore be used as a risk reduction strategy. PMID:26122632

    Urban areas derive significant changes of the ambient temperature generating specific challenges for society and infrastructure. Extreme temperature events, heat and cold waves affect the human comfort, increase the health risk, and require specific building regulations and emergency preparedness, strongly related to the magnitude and frequency of the thermal hazards. Rapid changes of the temperature put a particular stress for the urban settlements, and the topic has been approached constantly in the scientific literature. Due to its geographical position in a plain area with a temperate climate and noticeable continental influence, the city of Bucharest (Romania) deals with high seasonal and daily temperature variations. However, rapid fluctuations also occur at sub-daily scale caused by cold or warm air advections or by very local effects (e.g. radiative heat exchange, local precipitation). For example, in the area of Bucharest, the cold fronts of the warm season may trigger temperature decreasing up to 10-15 centigrades / hour, while warm advections lead to increasing of 1-2 centigrades / hour. This study focuses on the hourly and sub-hourly temperature variations over the period November 2014 - February 2016, using air temperature data collected from urban sensors and meteorological stations of the national network, and land surface temperature data obtained from satellite remote sensing. The analysis returns different statistics, such as magnitude, intensity, frequency, simultaneous occurrence and areal coverage of the rapid temperature fluctuations. Furthermore, the generating factors for each case study are assessed, and the results are used to define some preliminary patterns and enhance the urban temperature forecast at fine scale. The study was funded by the Romanian Programme Partnership in Priority Domains, PN - II - PCCA - 2013 - 4 - 0509 - Reducing UHI effects to improve urban comfort and balance energy consumption in Bucharest (REDBHI).

  14. The concept of marketing in the public-private partnership in the medical system in Romania

    During the transition period, the Romanian medical system, subject (like other areas) to a process of reform, had to go through a difficult path, not without obstacles (malpractice, underfunding, embezzlement scandals in the media etc.). Consequently, Romania has faced (and unfortunately still is still facing) the massive exodus of health professionals to countries where they can benefit from better working conditions and payment, and those who suffer from health care crisis are the patients. Reform means “the people in the system for the people”, which requires a change of mindset within the medical staff, especially in the continuous professional development. However, to talk about the quality of the medical act requires that all those involved in the medical system should create appropriate conditions – i.e. advanced technical equipment and appropriate salaries. In addition, as underfunding is the main cause of failure in the health system, that management remains the only tool that can lead to the appropriate use of the existing resources and the quality of health services. Therefore, the idea of public-private partnership – which occurred as a challenge, especially after the EU accession - can be considered a solution designed to improve the quality and cost of health services. In other words, the cooperation of the private sector with the public authority means increasing the rigor of the medical equipment performance, fostering professional competition, and an increased attention to the patient, in a word: performance. Currently, more and more frequently, the management has studied to identify opportunities for innovation in health care services in an attempt to bring together patients and practitioners in the field by resorting to the identification of the ways they can receive health care services promptly, fairly and efficiently. Therefore, a clear and responsible design in the spirit of ethics and medical ethic will help the marketing manager

    Education and awareness are efficient methods to mitigate the effects of natural disasters on communities. In this regard, the most receptive target group is the youth who have the potential to become vectors of information dissemination in their families and communities. In a country with significant seismic potential like Romania, the development of a Seismolab by means of an educational project is welcomed. The Seismolab operates within the Faculty of Environmental Science and Engineering at "Babeş-Bolyai" University, Cluj-Napoca, and it hosts activities conducted with the students of the faculty and pupils from Cluj and other schools involved in the RoEduSeis project. The RoEduSeis Project is a research and education project meant to develop the practical skills of primary, secondary and high school students in the field of Earth Sciences. A major objective of the project pursues the development and validation of new practical training methods for both teachers and students in the field of Earth Sciences. In this context, the Seismolab serves this particular aim by activities such as: training of students and teachers on conducting analyses and processing seismological data obtained from the educational seismographs in the Romanian educational seismic network; hands-on activities for pupils using educational resources developed through the project; documentary 2D and 3D movies and round tables on the topic of earthquakes and other natural risks. The students of the faculty use the data bases within subject matters in the curricula such as: Management of natural risks and disasters, Natural hazards and risks, Management of emergency situations etc. The seismometer used within the Seismolab will be connected to the above-mentioned educational network and the interaction between all the schools involved in the project will be conducted by the means of an e-learning platform. The results of this cooperation will contribute to a better education and awareness

    The Transylvanian Composite Total Petroleum System and the Transylvanian Neogene Suprasalt Gas Assessment Unit were identified in the Transylvanian Basin Province (4057), which lies entirely within the country of Romania. The assessment unit is composed of middle Miocene (Badenian) to Pliocene strata. Gas from the assessment unit is biogenic and originated from bacterial activity on dispersed organic matter in shales and siltstones. Gas migration is believed to be minimal, both vertically and laterally, with gases trapped in local stratigraphic traps and in structural traps (most likely domes and anticlinal folds created by salt diapirism) in the central part of the basin. For this reason, the gas fields also are concentrated in the central part of the basin. Reservoirs are isolated and composed of vertically stacked sandstones and siltstones sealed by shales and possibly by evaporite layers. Traps result from stratigraphic and facies changes within the entire assessment unit stratigraphic section. Some gas fields contain as much or more than a trillion cubic feet, but in most, the estimated resources are between 6 billion and 96 billion cubic feet. Petroleum exploration in the province is in the mature stage, which, combined with the geologic complexity of the region, is considered to limit future discoveries to a relatively few small fields. The undiscovered resources for the Transylvanian Basin Neogene Suprasalt Composite AU in the Transylvanian Hybrid Total Petroleum System (4057) are, at the mean, 2.083 trillion cubic feet of gas. No oil is produced in the basin. Rocks underlying the salt layers were not assessed for hydrocarbon potential.

    During the transition period, the Romanian medical system, subject (like other areas) to a process of reform, had to go through a difficult path, not without obstacles (malpractice, underfunding, embezzlement scandals in the media etc.). Consequently, Romania has faced (and unfortunately still is still facing) the massive exodus of health professionals to countries where they can benefit from better working conditions and payment, and those who suffer from health care crisis are the patients. Reform means "the people in the system for the people", which requires a change of mindset within the medical staff, especially in the continuous professional development. However, to talk about the quality of the medical act requires that all those involved in the medical system should create appropriate conditions - i.e. advanced technical equipment and appropriate salaries. In addition, as underfunding is the main cause of failure in the health system, that management remains the only tool that can lead to the appropriate use of the existing resources and the quality of health services. Therefore, the idea of public-private partnership - which occurred as a challenge, especially after the EU accession - can be considered a solution designed to improve the quality and cost of health services. In other words, the cooperation of the private sector with the public authority means increasing the rigor of the medical equipment performance, fostering professional competition, and an increased attention to the patient, in a word: performance. Currently, more and more frequently, the management has studied to identify opportunities for innovation in health care services in an attempt to bring together patients and practitioners in the field by resorting to the identification of the ways they can receive health care services promptly, fairly and efficiently. Therefore, a clear and responsible design in the spirit of ethics and medical ethic will help the marketing manager solve many

    Over 100 caves are known to develop in the Jurassic and Cretaceous limestone that outcrops on both sides of the Cerna Valley in southwestern Romania. High temperature anomalies are rather uncommon in the cave environment; however, in certain caves in the lower part of Cerna Valley one can measure air temperatures as high as 40°C. This situation is due to the presence of thermal water pooling or flowing through the caves or to the hot steam that rises along fractures from deeper thermal water pools. During the long evolution of the thermo-mineral activity along the Cerna Valley interaction has occurred on a wide scale between the cave host rock or/and cave sediments and the ascending hot steam or/and thermal solutions of all types (mainly sulfide-rich). The present work documents the products of these processes and record the occurrence of twenty-four secondary cave minerals (both of primarily or replacement origin) precipitated under particular cave environments. Among these, glauberite, apjonite, halotrichite, pickeringite, rapidcreekite, tamarugite, and darapskite are the most interesting. The mineral samples were investigated by means of X-ray diffraction, electron microprobe, Fourier-transformed infrared spectroscopy, and scanning electron microscope analyses with the scope of linking the cave minerals with possible hypogene speleogenetic processes. The isotopic measurements (δ34S) performed on sulfate speleothems contribute valuable information on both minerals and caves origin. Apart from two minerals (i.e., calcite and gypsum), which were identified in every cave investigated so far, all the others fall into three distinct associations that have resulted from specific reactions under highly particular settings in Diana (sulfate-dominated association), Adam (phosphate-dominated), and Great Sălitrari (sulfate/phosphate/nitrate-rich association) caves. These three remarkable cave occurrences are presented along with morphological features that confirm the

    Mafic-ultramafic cumulates enclosed in gabbroic-dioritic rocks form part of the Mesozoic Ditrău Alkaline Massif in the Eastern Carpathians, Romania. The poikilitic olivine- and pyroxene-rich and nearly mono mineralic hornblendite rocks display typical cumulate textures with early crystallised olivine (Fo75-73), diopside and augite. In the early stages of their genesis the amphibole was intercumulus whilst in later stages it acquired cumulus status as the fractionating magma evolved. Using major and trace element compositions of minerals and whole-rock samples the origin of these cumulates is determined and the parental magma composition and depth of emplacement are calculated. Cumulus clinopyroxene has more primitive composition than intercumulus amphibole suggesting closed system fractionation for the evolution of poikilitic olivine- and pyroxene-rich cumulates. The evolution of the amphibole-rich mesocumulates is more clearly the result of closed system crystallisation dominated by the precipitation of clinopyroxene and amphibole cumulus crystals. Lamprophyre dykes of the Ditrău Alkaline Massif are proposed to reflect multiple basanitic parental magma batches from which the cumulus olivine and clinopyroxene crystallised. Relative to these dykes the calculated equilibrium melts for intercumulus amphibole in the cumulates was more primitive whilst that for the cumulus amphibole was more evolved. The calculated crystallisation temperature and pressure of ~ 1000-1050 °C and ~ 0.7 GPa, based on the composition of the amphiboles, indicate crystallisation at lower crustal depths. Rare earth element compositions are consistent with an intra-plate tectonic setting.

    The Transylvanian Plain, Romania is an important region for agronomic productivity. However, limited soils data and adoption of best management practices hinder land productivity. Soil temperatures of the Transylvanian Plain were evaluated using a set of twenty datalogging stations positioned throughout the plain. Soil temperatures were monitored at the surface and at 10, 30, and 50 cm depths, and soil moisture was monitored at 10 cm. Preliminary results indicate that most soils of the Transylvanian Plain will have a mesic temperature regime. However, differences in seasonal warming and cooling trends across the plain were noted. These have important implications for planting recommendations. Growing degree days (GDDs) are preferred over maturity ratings, because they can account for temperature anomalies. The crop being considered for this study was corn. The base temperature (BT) was set at 10oC, and the upper threshold was 30oC. Two methods were used to calculate GDDs; 1) minimum and maximum daily temperatures, and 2) 24 h of averaged temperature data. Growing degree days were run from 110-199 day of year (DOY) to represent approximate planting date to tasseling. The DOY that 694 accumulated growing degree days (AGDDs) was reached at each site was then analyzed to identify differences across the TP. Three sites failed to reach 694 AGDDs by DOY 199, and were excluded from comparisons to other results. Averaged values were used to create spline interpolation maps with ArcMap 9.2 (ESRI, Redlands, CA, USA). The southeastern portion of the TP was found to tassel a month earlier assuming a planting date of 109 DOY. Four DeKalb® corn hybrids were then selected based on GDDs to tasseling, drydown, drought tolerance, and insect resistance. With a better understanding of the GDD trends across the TP, more effective planting and harvesting could be accomplished by Romanian farmers to maximize agronomic production.

    The Hurst exponent of very long birth time series in Romania has been extracted from official daily records, i.e. over 97 years between 1905 and 2001 included. The series result from distinguishing between families located in urban (U) or rural (R) areas, and belonging (Ox) or not (NOx) to the orthodox religion. Four time series combining both criteria, (U,R) and (Ox, NOx), are also examined. A statistical information is given on these sub-populations measuring their XX-th century state as a snapshot. However, the main goal is to investigate whether the "daily" production of babies is purely noisy or is fluctuating according to some non trivial fractional Brownian motion, - in the four types of populations, characterized by either their habitat or their religious attitude, yet living within the same political regime. One of the goals was also to find whether combined criteria implied a different behavior. Moreover, we wish to observe whether some seasonal periodicity exists. The detrended fluctuation analysis technique is used for finding the fractal correlation dimension of such (9) signals. It has been first necessary, due to two periodic tendencies, to define the range regime in which the Hurst exponent is meaningfully defined. It results that the birth of babies in all cases is a very strongly persistent signal. It is found that the signal fractal correlation dimension is weaker (i) for NOx than for Ox, and (ii) or U with respect to R. Moreover, it is observed that the combination of U or R with NOx or OX enhances the UNOx, UOx, and ROx fluctuations, but smoothens the RNOx signal, thereby suggesting a stronger conditioning on religiosity rituals or rules.

    Land use change is a major threat to global biodiversity. Forest species face the dual threats of deforestation and intensification of forest management. In regions where forests are under threat, rural landscapes that retain structural components of mature forests potentially provide valuable additional habitat for some forest species. Here, we illustrate the habitat value of traditional wood pastures for a woodpecker assemblage of six species in southern Transylvania, Romania. Wood pastures are created by long-term stable silvo-pastoral management practices, and are composed of open grassland with scattered large, old trees. Because of their demanding habitat requirements, woodpeckers share habitat with many other bird species, and have been considered as possible indicator species for bird species diversity. We first compared woodpecker assemblages between forests and wood pastures. Second, we grouped features of wood pastures into three spatial contexts and addressed how these features related to the occurrence of three woodpecker species that are formally protected. Woodpecker species composition, but not the number of species, differed between forests and wood pastures, with the green woodpecker occurring more commonly in wood pastures, and the lesser spotted woodpecker more commonly in forests. Within wood pastures, the intermediate context (especially surrounding forest cover) best explained the presence of the grey-headed and middle spotted woodpecker. By contrast, variables describing local vegetation structure and characteristics of the surrounding landscape did not affect woodpecker occurrence in wood pastures. In contrast to many other parts of Europe, in which several species of woodpeckers have declined, the traditional rural landscape of Transylvania continues to provide habitat for several woodpecker species, both in forests and wood pastures. Given the apparent habitat value of wood pastures for woodpeckers we recommend wood pastures be explicitly

    An increasing number of free and open access global digital elevation models has become available in the past 15 years and these DEMs have been widely used for the assessment of landslide susceptibility at medium and small scales. Even though the global vertical and horizontal accuracies of each DEM are known, what it is still unknown is the uncertainty that propagates from the first and second derivatives of DEMs, like slope gradient, into the final landslide susceptibility map For the present study we focused on the assessment of the uncertainty propagation from the following digital elevation models: SRTM 90m spatial resolution, ASTERDEM 30m spatial resolution, EUDEM 30m spatial resolution and the latest release SRTM 30m spatial resolution. From each DEM dataset the slope gradient was generated and used in the landslide susceptibility analysis. A restricted number of spatial predictors are used for landslide susceptibility assessment, represented by lithology, land-cover and slope, were the slope is the only predictor that changes with each DEM. The study makes use of the first national landslide inventory (Micu et al, 2014) obtained from compiling literature data, personal or institutional landslide inventories. The landslide inventory contains more than 27,900 cases classified in three main categories: slides flows and falls The results present landslide susceptibility maps obtained from each DEM and from the combinations of DEM datasets. Maps with uncertainty propagation at country level and differentiated by topographic regions from Romania and by landslide typology (slides, flows and falls) are obtained for each DEM dataset and for the combinations of these. An objective evaluation of each DEM dataset and a final map of landslide susceptibility and the associated uncertainty are provided

    Moldavian Plateau, Eastern Romania is an area where soil erosion is a widespread phenomenon, given the dissected topography, patterns of land use and climate. Gully erosion plays an important role in the soil erosion processes. We have used a high resolution DEMs, high resolution satellite imagery and old aerial images to delineate gullies in the Șacovâț catchment. This catchment has a surface of 314 kmp from which 17 kmp are covered by gullies, resulting a density of 0.05%. We have identified various gully types: continuous and discontinuous, bank gullies, hillslope gullies, road and path gullies and relict gully systems. Road and path gullies have small dimensions, under 2000 sqm, 2 to 5 m in width, up to 500 m in length, 1-2 m in depth, and can be discontinuous. Bank gullies have under 2000 sqm, up to 2000 sqm in surface and up to 500 m in length. Their depth can be similar to bank height, up to 5 m. Hillslope gullies have under 1 km in length, under 100 000 sqm surface, up to 3 in depth and around 20 m channel width. Small hillslope gullies (1000 to 2000 sqm) are in general discontinuous. Relict gully systems have are big dimensions (300 000 to 1 000 000 sqm surface, widths of the channel up to 250 m, 1 to 3 km length, and up to 25 m depth of the channel) and usually present dendritic patterns, with newer bank and hillslope gullies which are hydrologically and morphologically connected to the relict gully channel. Is usual for these gullies to have the channel filled with bank failures and landslides triggered by its deepening. The gullies from Șacovǎț catchment are in continuous evolution, the relict gullies needing dating while the fresh gullies needing monitoring, especially in the context of climate and land use changes due to deforestation.

    The aim of the study was to perform a nationwide evaluation of the frequency, incidence and trends of diabetes-related LEA (lower extremities amputations) in Romania. We have retrospectively analysed DRG data (ICD 10 AM codes) from all hospitals in the country, over a 5 year period (2006-2010). Knowing the shortcomings of this approach, we have assumed that our study can serve as a platform for future comparisons. The total number of non-traumatic diabetes related LEA procedures was 24,312, they were performed in 16,873 patients with diabetes, 22.55% with type 1 diabetes, 70.26 with type 2 diabetes and 7.19% with non-specified diabetes at discharge. The total number of hospital admissions for these patients was 46,985. During the five years of the study there was an increase in the absolute number of major amputations (above the ankle), as well as of minor amputations. The rate of amputations decreased in type 1 diabetes, from baseline (2006): -8.15% in 2007, -25.83% in 2008, -23.43% in 2009, -27.71% in 2010, whereas it increased in type 2 diabetes in the respective years: 16.96%, 60.75%, 66.91%, and 104.64%, due to an increase in minor amputations and mainly in elderly people. Male: female amputations rate was 2:1 in type 1 diabetes patients and 2.4:1 in type 2 diabetes patients. This study, the first of its kind in the Romanian population, offers a starting point for future comparisons and identifies a target for preventive measures.

The quantitative interpretation of the resistivity geoelectrical vertical tests, and the correlation with the geological structure identified 3 sliding surfaces, from which only the upper one (2-6m depth) was known before the stability works. There were localized the rainfall waters circulation and accumulation zones, areas with high sliding risk. Same results were obtained in sliding zones, been localized the principal elements of the landslides, with practical implications in land instability and estimation of the evolution of the destructive phenomena mechanisms. With this study we try to quantify the complex relationship between the natural factors that generate the terrain instability phenomena and the intensity of the socio-economic effects, at a regional and local scale, by correlating the engineering geology information and geophysical data. Recent seismic research program (September 2009) conceived for "La Butoi" landslide, Telega locality, aims to a specific monitoring of the dynamic deformations, more active in the central part of the landslide, with reference to the shallow seismic refraction information obtained in the 2004 - 2005 period. The investigations were performed on a seismic lines network, and two seismic boundaries, in the shallow seismic section, were exhibited. As a result, one can observe the curvature tendency of the first arrivals sin-phase for the end-off shot devices, setting off the velocity increasing regime with depth; relative high variations and irregularities of

    With the development of economy, the health of river ecosystem is severely threatened because of the increasing effects of human activities on river ecosystem. In this paper, the authors assessed the river ecosystem health in aspects of chemical integrity and biological integrity, using the criterion in water quality, nutrient, and benthic macroinvertebrates of 73 samples in Haihe River Basin. The research showed that the health condition of river ecosystem in Haihe River Basin was bad overall since the health situation of 72. 6% of the samples was "extremely bad". At the same time, the health situation in Haihe River Basin exhibited obvious regional gathering effect. We also found that the river water quality was closely related to human activities, and the eutrophication trend of water body was evident in Haihe River Basin. The biodiversity of the benthic animal was low and lack of clean species in the basin. The indicators such as ammonia nitrogen, total nitrogen and total phosphorus were the key factors that affected the river ecosystem health in Haihe River Basin, so the government should start to curb the deterioration of river ecosystem health by controlling these nutrients indicators. For river ecosystem health assessment, the multi-factors comprehensive evaluation method was superior to single-factor method.

  9. Sharing the rivers. Overview.

    PubMed

    Postel, S

    1996-01-01

    Globally, water use has more than tripled since 1950, and the answer to this rising demand generally has been to build more and bigger water supply projects, particularly dams and river diversions. As population and consumption levels grow, more and more rivers are being dammed, diverted, or overtapped to supply increasing volumes of water to cities, industries, and farms. Among these rivers are the Nile in northeast Africa, the Ganges in south Asia, the Amu Dar'ya and Syr Dar'ya in the Aral Sea basin, the Huang He (Yellow River) in China, and the Colorado. Subsequently, such massive change in the global aquatic environment generated deterioration, decline, and in some cases, collapse in aquatic systems. In addition, competition for water is increasing not only between the human economy and the natural environment, but also between and within countries. Water scarcity is a potential source of conflict. Forces such as the depletion of resources; population growth; and unequal distribution or access can create political conflicts. Achieving more sustainable patterns of water use, restoring and maintaining the integrity of river systems, and cooperation within and between countries will not only protect the aquatic environment, but also avert conflict.

    2013-12-01

    At the watershed scale, a number of complex biogeochemical processes govern riverine geochemistry, and the use of multiple isotopic and trace element analyses has the potential to elucidate these dynamic processes. Such a study was undertaken within the Tisza River Basin (TRB) which is the largest river basin within the Carpathian Basin of Central Europe. The TRB stretches 157,186 km2 and encompasses Romania, Hungary, Serbia, Slovakia, and Ukraine. Geologically, the TRB covers the Pannonian Basin, the Eastern, Western and Southern Carpathians and the Apuseni Mountains. These units have a very complex geology and lithology. The formations range from igneous and metamorphic rocks to sediments, covering a time span from Paleozoic to Quaternary. Our study aimed to determine the influence of various bedrock lithologies on the water chemistry of tributaries and the impact of the biogeochemical and anthropogenic factors on the downstream chemical evolution of the rivers. Twenty-three sampling locations were chosen within the TRB based on the dominant bedrock lithology of the drainage area. In June of 2013, water and rock samples were collected from the Apuseni Mountains and the Southern Carpathians, sampling two main tributary systems - the Cris (Körös) and Mure (Maros) Rivers - and the Lower Tisa (Tisza) River. At each sampling location, field parameters (temperature, pH, dissolved oxygen, and specific conductivity) were measured and water samples were retrieved. Water samples were analyzed for alkalinity, major and minor cations (Fe, Al, Si, Mn, Cu, Sr, Cd, Ni, Zn, Ca, Mg, Na, Se, Pb, As, K) and anions (SO42-, NO3-, Cl-, F-, PO43-), as well as 87Sr/86Sr ratios, and δ2D and δ18O values. Tributaries drained primarily by carbonates tended to exhibit more of an effect on the downstream water chemistry compared to areas drained by silicate rocks, which had little effect on mainstem rivers. Additionally, δ2D and δ18O values (ranging from -80.53 to -41.97‰ for δ2D and

    The fall of the communist regime in Romania at the end of 1989 and the ensuing transition to the market economy brought about many changes in the use of agricultural land. These changes combined with the action of climatic factors led, in most cases, to negative effects increasing the risk of degradation of agricultural land. This study aims to assess and monitor the risk of land degradation in Baragan Plain, Romania, for the period 1988-2011 using Landsat Thematic Mapper (TM) and Spectral Mixture Analysis (SMA). Each satellite image was classified through the Decision Tree Classifier (DTC) method; then, on the basis of certain threshold values, we obtained maps of land degradation and maps showing the passage from various classes of land use/land cover (LULC) to land degradation. The results indicate that during the intermediary periods there was an ascending and descending trend in the risk of land degradation determined by the interaction of climatic factors with the social-economic ones. For the entire period, the overall trend was ascending, the risk of land degradation increasing by around 4.60 % of the studied surface. Out of the climatic factors, high temperatures and, implicitly, drought were the most significant. The social-economic factors are the result of the changes which occurred after the fall of the communist regime, the most important being the fragmentation of agricultural land and the destruction of the irrigation system.

    Background We aimed to verify the issue of the ethics audit and its use in the system of accreditation of hospitals. It presents the results of a survey conducted among hospital managers from Romania. Methods: Our article highlights the results of the second part of a research carried out in 2012 on the pertinence and the structure of the ethics audit integrated within the accreditation process of hospitals, according the opinion of the 47 executives and managers involved in the quality management of Romania hospitals. The data have been gathered with the aid of the online questionnaire. Results: An ethics audit integrated within the accreditation process of hospitals should include primarily the respect of the patients’ rights, the good relations of the institutions with its patients and the respect of the moral rights of the employees. Conclusion: The usefulness of this study is due to the fact that it consults precisely those who should really contribute to the creation, application and monitoring of ethical policies and instruments necessary in every hospital which are permanently under the scrutiny of public opinion and confront themselves with the obligation to give a thorough account of their results and spending of the public resources. This study gain consistency as the relevant aspects that could form the structure of a hospital ethics audit are identified with the direct help of the managers responsible for implementing it.

    During the last decades a growing number of heat waves have been observed in Romania during summer. The current index used in the National Meteorological Administration in Bucharest for quantifying human comfort is a temperature-humidity index (ITU). The heat warning is issued by the National Forecasting Center in two stages: warning stage 1 (alert stage) when the ITU value is between 66 and 79 units and, warning stage 2 (risk stage) when the ITU value is greater than 80 units. This paper presents the trends of the number of days with warnings (alert and risk, separately) at 15 stations located in the south and south - east of Romania's territory during summer for the period 1961-2007. Hourly data of air temperature and relative humidity for the interval 12-18 local time have been used for the study. The frequency of warnings during that hourly interval is assessed for each month (June, July and August) based on ITU thresholds. Finally, the spatial distribution of the warning frequencies is drawn as useful information for tourism and other environmental activities.

    The fall of the communist regime in Romania at the end of 1989 and the ensuing transition to the market economy brought about many changes in the use of agricultural land. These changes combined with the action of climatic factors led, in most cases, to negative effects increasing the risk of degradation of agricultural land. This study aims to assess and monitor the risk of land degradation in Baragan Plain, Romania, for the period 1988-2011 using Landsat Thematic Mapper (TM) and Spectral Mixture Analysis (SMA). Each satellite image was classified through the Decision Tree Classifier (DTC) method; then, on the basis of certain threshold values, we obtained maps of land degradation and maps showing the passage from various classes of land use/land cover (LULC) to land degradation. The results indicate that during the intermediary periods there was an ascending and descending trend in the risk of land degradation determined by the interaction of climatic factors with the social-economic ones. For the entire period, the overall trend was ascending, the risk of land degradation increasing by around 4.60 % of the studied surface. Out of the climatic factors, high temperatures and, implicitly, drought were the most significant. The social-economic factors are the result of the changes which occurred after the fall of the communist regime, the most important being the fragmentation of agricultural land and the destruction of the irrigation system.

    The paper reports the prevalence and geographical distribution of Borrelia burgdorferi sensu lato (s.l.) and its genospecies in 12,221 questing Ixodes ricinus ticks collected at 183 locations from all the 41 counties of Romania. The unfed ticks were examined for the presence of B. burgdorferi s.l. by PCR targeting the intergenic spacer 5S-23S. Reverse line blot hybridization (RLB) and restriction fragment length polymorphism (RFLP) analysis were performed for identification of B. burgdorferi genospecies. The overall prevalence of infection was 1.4%, with an average local prevalence between 0.75% and 18.8%. B. burgdorferi s.l. was found in ticks of 55 of the 183 localities. The overall prevalence B. burgdorferi s.l. in ticks in the infected localities was 3.8%. The total infection prevalence was higher in female ticks than in other developmental stages. Three Borrelia genospecies were detected. The most widely distributed genospecies was B. afzelii, followed by B. garinii and B. burgdorferi sensu stricto (s.s.). The study is the first countrywide study and the first report of B. burgdorferi s.s. in Romania. The distribution maps show that higher prevalences were recorded in hilly areas, but Lyme borreliosis spirochetes were also present in forested lowlands, albeit with a lower prevalence.

    The role of statistical downscaling is to model the relationship between large-scale atmospheric circulation and climatic variables on a regional and sub-regional scale, making use of the predictions of future circulation generated by General Circulation Models (GCMs) in order to capture the effects of climate change on smaller areas. The study presents a statistical downscaling model based on a neural network-based approach, by means of multi-layer perceptron networks. Sub-daily temperature data series from 81 meteorological stations over Romania, with full data records are used as predictands. As large-scale predictor, the NCEP/NCAD air temperature data at 850 hPa over the domain 20-30E / 40-50N was used, at a spatial resolution of 2.5×2.5 degrees. The period 1961-1990 was used for calibration, while the validation was realized over the 1991-2010 interval. Further, in order to estimate future changes in air temperature for 2021-2050 and 2071-2100, air temperature data at 850 hPa corresponding to the IPCC A1B scenario was extracted from the CNCM33 model (Meteo-France) and used as predictor. This work has been realized within the research project "Changes in climate extremes and associated impact in hydrological events in Romania" (CLIMHYDEX), code PN II-ID-2011-2-0073, financed by the Romanian Executive Agency for Higher Education Research, Development and Innovation Funding (UEFISCDI).

    The Pearl River, or Zhujiang River system is China's third longest river, after the Yangtze and Yellow Rivers. The Pearl River has three principal tributaries, namely, the Xijiang River, Beijiang River and Dongjiang River. It also receives several other small tributaries developed within the Pearl River Delta. Its average annual flow rate approximately 10 , 000m3s-1 is exceeded only by the Yangtze River. Its length is 2 , 214 km and drains an area of 453 , 690km2, most of which is in Southern China and with a small part in Vietnam. Parts of the provinces of Yunnan, Guizhou, Guangxi, Guangdong, Hunan and Jiangxi drain to the Pearl River system.

    Assessing the quality of water in every location of the Nation would not be practical. Therefore, NAWQA investigations are conducted within 59 selected areas called study units (fig. 1). These study units encompass important river and aquifer systems in the United States and represent the diverse geographic, waterresource, land-use, and water-use characteristics of the Nation. The Delaware River Basin is one of 15 study units in which work began in 1996. Water-quality sampling in the study unit will begin in 1999. This fact sheet provides a brief overview of the NAWQA program, describes the Delaware River Basin study unit, identifies the major water-quality issues in the basin, and documents the plan of study that will be followed during the study-unit investigation.

  10. Comparison and validation of Logistic Regression and Analytic Hierarchy Process models of landslide susceptibility in monoclinic regions. A case study in Moldavian Plateau, N-E Romania

    2014-05-01

    The regions with monoclinic geological structure are large portions of earth surface where the repetition of similar landform patterns is very distinguished, the scarps of cuestas being characterized by similar values of morphometrical variables. Landslides are associated with these scarps of cuestas and consequently, a very high value of landslide susceptibility can be reported on its surface. In these regions, landslide susceptibility mapping can be realized for the entire region, or for test areas, with accurate, reliable, and available datasets, concerning multi-temporal inventories and landslide predictors. Because of the similar geomorphologic and landslide distribution we think that if any relevance of using test areas for extrapolating susceptibility models is present, these areas should be targeted first. This study case try to establish the level of usability of landslide predictors influence, obtained for a 90 km2 sample located in the northern part of the Moldavian Plateau (N-E Romania), in other areas of the same physio-geographic region. In a first phase, landslide susceptibility assessment was carried out and validated using logistic regression (LR) approach, using a multiple landslide inventory. This inventory was created using ortorectified aerial images from 1978 and 2005, for each period being considered both old and active landslides. The modeling strategy was based on a distinctly inventory of depletion areas of all landslide, for 1978 phase, and on a number of 30 covariates extracted from topographical and aerial images (both from 1978 and 2005 periods). The geomorphometric variables were computed from a Digital Elevation Model (DEM) obtained by interpolation from 1:5000 contour data (2.5 m equidistance), at 10x10 m resolution. Distance from river network, distance from roads and land use were extracted from topographic maps and aerial images. By applying Akaike Information Criterion (AIC) the covariates with significance under 0.001 level

    1985-01-01

    The water and sulfur runoff data for 54 large river basins were assembled, covering 65% of the nondesert land area of the world. The sulfur concentration ranges from 0.5 mg S/L for the West African rivers Niger and Volta to 100 mg S/L in the Colorado River; the world average is 3.2 mg S/L. The concentrations in central and eastern Europe as well as central and eastern North America exceed 8 mg S/L. The sulfur runoff density is also highest in the river basins over these industrialized regions, exceeding 2 g S/m2/yr. However, high sulfur runoff density in excess of 3 g S/m2/yr is also measured over the Pacific islands New Zealand and New Guinea and the archipelagos of Indonesia and the Philippines. The natural background sulfur runoff was estimated by assuming that South America, Africa, Australia, and the Pacific Islands are unperturbed by man and that the average river sulfur concentration is in the range 1-3 mg S/L. Taking these background concentration values, the man-induced sulfur runoff for Europe ranges between 2 and 8 times the natural flow, and over North America, man's contribution ranges between 1 and 5 times the natural runoff. The global sulfur flow from nondesert land to the oceans and the Caspian Sea is estimated as 131 Tg S/yr, of which 46-85 Tg S/yr is attributed to natural causes. The regional river sulfur runoff pattern discussed in this paper does not have enough spatial resolution to be directly applicable to studies of the environmental effects of man-induced sulfur flows. However, it points to the continental-size regions where those perturbations are most evident and to the magnitude of the perturbations as expressed in units of the natural flows.

    1997-12-01

    There is a large uncertainty in our understanding of the behavior of osmium during weathering and transport into deep oceans and the osmium budget of the oceans. The problem stems chiefly from the lack of osmium data on the dissolved load in the rivers and in the estuaries. In this study, the concentration and isotopic composition of osmium have been determined in three North American rivers (the Mississippi, the Columbia, and the Connecticut) and one river draining central Europe and flowing into the Baltic Sea (the Vistula). Osmium concentration in the Mississippi and the Vistula is about 45 femto mol kg{sup -1}; it is about 14 and 15 femto mol kg{sup -1} for the Connecticut and the Columbia, respectively. The {sup 187}Os/{sup 186}Os ratios estimated for the Mississippi and the Vistula are 10.4 and 10.7, respectively. For the Connecticut and the Columbia {sup 187}Os/{sup 186}Os = 8.8 and 14.4, respectively. Of all the rivers examined, the Mississippi is by far the largest, supplying {approximately}1.6% of the total annual world river flow. Its osmium isotopic composition is identical to the upper Mississippi valley loesses indicating (1) congruent dissolution of the bedrock and (2) little or no impact of anthropogenic sources on the osmium isotopic composition of the dissolved load. The latter observation indicates that the upper limit of the anthropogenic input in the dissolved osmium load of the Mississippi outflow is about 250 g yr{sup -1}. While the osmium concentration of the Vistula is high the isotopic composition does not appear to have been affected by substantial pollution. The river data can be used to put limits on the mean residence time of osmium in the oceans ({bar {tau}}{sub Os}) and on the osmium budget of the oceans. 17 refs., 1 fig., 1 tab.

  14. The influence of large-scale atmospheric circulation on the variability of Barlad river streamflow

    NASA Astrophysics Data System (ADS)

    Chelcea, Silvia; Ionita, Monica

    2010-05-01

    The seasonal variability of Barlad river flow, situated in the eastern part of Romania, in connection with large-scale atmospheric circulation is analyzed for the period 1951-2005. The relationship with precipitation (PP) and temperature (TT) in the European sector, global sea surface temperature (SST), atmospheric circulation over the Northern Hemisphere and the moisture transport is investigated. Applying correlation and composite analyses, it has been found that the variability of winter flow is influenced by a North Atlantic Oscillation (NAO) like pattern. On seasonal time scale, high flow anomalies are strongly correlated with winter TT and PP anomalies over land. There is an out-of-phase relationship between Barlad flow and TT over Scandinavian region and an in-phase relationship with TT anomalies over the southern part of Europe. This pattern in the TT field is similar to the negative phase of the NAO. High anomalies of the river flow are associated with a tripole-like pattern in the North Atlantic and with negative SST anomalies in the central North Pacific and positive anomalies in the eastern and central tropical Pacific. Positive anomalies of winter streamflow are associated with positive anomalies of sea level pressure (SLP) and 500 hPa geopotential height (G500) centered over the northern part of Europe and Greenland and negative anomalies centred over the mid Atlantic Ocean and the southern part of Europe. Vector plots of the vertically integrated water vapour transport composites show that during years with low flow anomalies there is a significant reduction of the water vapour transport downstream southern Europe and a shift of the axis of the water vapour transport towards Scandinavia are. Low flow anomalies are also found in connection with an intense zone of divergence over the eastern part of Romania, where the catchement area of Balrad river is situated. Wavelet and cross spectra techniques are also used to identify the coherent cyclic and non

    Background Traditional habitat knowledge is an understudied part of traditional knowledge. Though the number of studies increased world-wide in the last decade, this knowledge is still rarely studied in Europe. We document the habitat vocabulary used by Csángó people, and determine features they used to name and describe these categories. Study area and methods Csángó people live in Gyimes (Carpathians, Romania). The area is dominated by coniferous forests, hay meadows and pastures. Animal husbandry is the main source of living. Data on the knowledge of habitat preference of 135 salient wild plant species were collected (2908 records, 44 interviewees). Data collected indoors were counterchecked during outdoor interviews and participatory field work. Results Csángós used a rich and sophisticated vocabulary to name and describe habitat categories. They distinguished altogether at least 142–148 habitat types, and named them by 242 habitat terms. We argue that the method applied and the questions asked (‘what kind of place does species X like?’) helped the often implicit knowledge of habitats to be verbalized more efficiently than usual in an interview. Habitat names were highly lexicalized and most of them were widely shared. The main features were biotic or abiotic, like land-use, dominant plant species, vegetation structure, successional stage, disturbance, soil characteristics, hydrological, and geomorphological features. Csángós often used indicator species (28, mainly herbaceous taxa) in describing habitats of species. To prevent reduction in the quantity and/or quality of hay, unnecessary disturbance of grasslands was avoided by the Csángós. This could explain the high number of habitats (35) distinguished dominantly by the type and severity of disturbance. Based on the spatial scale and topological inclusiveness of habitat categories we distinguished macro-, meso-, and microhabitats. Conclusions Csángó habitat categories were not organized

    Several source parameters (source dimensions, slip, particle velocity, static and dynamic stress drop) are determined for the moderate-size October 27th, 2004 ( MW = 5.8), and the large August 30th, 1986 ( MW = 7.1) and March 4th, 1977 ( MW = 7.4) Vrancea (Romania) intermediate-depth earthquakes. For this purpose, the empirical Green's functions method of Irikura [e.g. Irikura, K. (1983). Semi-Empirical Estimation of Strong Ground Motions during Large Earthquakes. Bull. Dis. Prev. Res. Inst., Kyoto Univ., 33, Part 2, No. 298, 63-104., Irikura, K. (1986). Prediction of strong acceleration motions using empirical Green's function, in Proceedings of the 7th Japan earthquake engineering symposium, 151-156., Irikura, K. (1999). Techniques for the simulation of strong ground motion and deterministic seismic hazard analysis, in Proceedings of the advanced study course seismotectonic and microzonation techniques in earthquake engineering: integrated training in earthquake risk reduction practices, Kefallinia, 453-554.] is used to generate synthetic time series from recordings of smaller events (with 4 ≤ MW ≤ 5) in order to estimate several parameters characterizing the so-called strong motion generation area, which is defined as an extended area with homogeneous slip and rise time and, for crustal earthquakes, corresponds to an asperity of about 100 bar stress release [Miyake, H., T. Iwata and K. Irikura (2003). Source characterization for broadband ground-motion simulation: Kinematic heterogeneous source model and strong motion generation area. Bull. Seism. Soc. Am., 93, 2531-2545.] The parameters are obtained by acceleration envelope and displacement waveform inversion for the 2004 and 1986 events and MSK intensity pattern inversion for the 1977 event using a genetic algorithm. The strong motion recordings of the analyzed Vrancea earthquakes as well as the MSK intensity pattern of the 1977 earthquake can be well reproduced using relatively small strong motion

    The current study was carried out within the FP7 ECLISE project in the Eastern Lower Danube Plain (Bărăgan Plain), one of the major agricultural areas in Romania. In this region, climate change signals are becoming more evident being predominantly characterized by increasing temperatures, decreasing of precipitations and intensification of extreme events in terms of frequency, intensity and duration. Over the past decades, the effects of extreme climatic phenomena on crop production have been ever more severe (very low outputs in the droughty years, significant crop losses during flooding periods, hailstorms, etc.). Concurrently, these effects have been the result of a whole range of complex interactions with other environmental, social, economic and political factors over the post-communist period. Using questionnaires survey for small individual households and large agricultural farms, focus group interviews and direct field observation, this study analyses the farmers' perception in terms of climate change, the impact of climate change on agriculture and how the farmers react and adapt to these changes. The current study have revealed that all farmers believe drought as being by far the most important climatic factor with major impact on agricultural production, followed by acid rains, hail storms and ground frost, facts evidenced also by the climatic diagnosis of the region. The majority of respondents have taken adaptation agricultural measures in response to changes in climate conditions (drought resistant seeds, modern technology to keep the moisture in the soil, etc.), but they consider that a national strategy for mitigating the effects of climate change would be more effective in this respect. Also, in order to correlate the farmers' perception of climate change and climatic factors, the authors used and processed a wide range of meteorological data (daily, monthly and annual from the most representative meteorological stations in the study-area), as

    The Middle to Upper Paleolithic transition is one of the crucial periods of change in the prehistory of Europe due to the full emergence, continent-wide, of modern human technologies, detrimental of Neanderthal survival. Knowledge about the transition is vast, however, the evidence for cultural and technological developments in the Carpathian - Lower Danube area is still rather sparse. Here we discuss latest results arising from an archaeological-chronological investigation of a Middle Paleolithic context within the Varghis karst, eastern Transylvania, Romania. Combining our results with these of previous excavations, we can distinguish several stages of habitation in the area comprising a rock shelter connected to a newly discovered filled-in cave entrance. Reanalysis of the deeper stratigraphy previously unexcavated shows that at least two main habitation levels have been preserved. In both levels, the bone assemblages (Bos/Bison, Capra, Canis lupus, Ursus spaeleus) directly associated with lithics point to human-accumulation of material. In order to augment the typological cultural considerations, we applied direct radiocarbon dating on bones from within the occupation layers and on scattered charcoal, for the latter following a two-step combustion protocol (1). Radiocarbon dating on bones suggests the lowermost occupation layer is >43.4 radiocarbon kyr BP old, whereas the preliminary infrared stimulated luminescence (IRSL) ages on the lowermost productive layer and above it indicate surprisingly old ages of ca. 120 kyr and respectively, ca. 70 kyr. Multiple-protocol dating of charcoal found within the two habitation layers produced ages >38 radiocarbon kyr BP, suggesting that the lowermost habitation layer unequivocally pertains to the Middle Paleolithic industries. For the upper productive layer, radiocarbon dating of charcoal found 20 cm above it produced a surprisingly young age of 17.4 radiocarbon kyr BP. However, as the carbon content of this sample was

    The Apuseni Mountains in Romania take a central position in the Alpine Carpathian Dinaride system between the Pannonian basin in the West and the Transylvanian basin in the East. Following the final Mid-Cretaceous obduction of the East Vardar ophiolite a NW-vergent nappe stack formed, which involves from bottom to top: Tisza- (Bihor and Codru) and Dacia-derived (Biharia) units, overlain by the South Apuseni or Transylvanian ophiolite belt (see Schmid et al, 2008). This study tries to provide new and additional information on the complex structural and metamorphic evolution of these units, from the onset of obduction during Jurassic times, to the (final?) exhumation processes observed during the Eocene (according to Merten, 2011). Based on observed stretching lineations, kinematic indicators such as porphyroclasts, shearbands etc. were analyzed to establish a relative chronological order of deformation and tectonic transport. Microstructural studies provided additional data on the relative succession of events and the relevant synkinematic temperatures. A thermochronological study, based on the integration of newly aquired Rb-Sr, Sm-Nd, Ar-Ar and fission track ages with existing data allowed the construction of a time-temperature deformation path. Our data indicate three major events, a Late Jurassic-Earliest Cretaceous exhumation event, which cannot be directly constrained by structural data so far. Yet the position of the Transsylvanian ophiolites tectonically overlying the Biharia unit as well as distinct thermochronological data are self-explaining.

    The Guadalupian (Mid-Permian) Highiș massif (Apuseni Mountains, Romania) displays a bimodal igneous suite of mafic (gabbro, diorite) and A-type felsic (alkali feldspar granite, albite granite, and hybrid granodiorite) rocks. Amphibole is widespread throughout the suite, and yields markedly high chlorine contents. Three groups are identified: Cl-rich potassic hastingsite (2.60-3.40 wt% Cl) within A-type felsic rocks and diorite, mildly Cl-rich pargasite to hornblende (0.80-1.90 wt% Cl) within gabbro, and low F-Cl hornblende within gabbro and hybrid granodiorite. Coexisting biotite is either Cl-rich within diorite, or F-Cl-poor to F-rich within A-type felsic rocks. Chlorine and fluorine are distributed in both mafic phases, according to the F-Fe and Cl-Mg avoidance rules. The low-Ti contents suggest subsolidus compositions. Cl-rich amphibole within diorite and A-type felsic rocks yields a restricted temperature range - from 575 °C down to 400 °C, whereas mildly Cl-rich amphibole within gabbro displays the highest range - from 675 to 360 °C. Temperatures recorded by Cl-rich biotite within diorite range from 590 to 410 °C. Biotite within A-type felsic rocks yields higher temperatures than amphibole: the highest values- from 640 to 540 °C - are recorded in low-F-Cl varieties, whereas the lowest values- from 535 to 500 °C - are displayed by F-rich varieties. All data point to halogen-rich hydrothermal fluids at upper greenschist facies conditions percolating through fractures and shear zones and pervasively permeating the whole Highiș massif, with F precipitating as interstitial fluorite and Cl incorporating into amphibole, during one, or possibly several, hydrothermal episodes that would have occurred during a ~ 150 My-long period of time extending from the Guadalupian (Mid-Permian) to the Albian (Mid-Cretaceous).

    Landslides are widespread phenomena that contribute to shape the landscape. Assessing the time sequence of landslide activity during the Holocene can help (i) better frame the present day landslide distribution in the wider context of climate change and (ii) better define landslide hazard to take adequate mitigation measures to preserve the elements at risk such as archaeological heritage and currently used structures and infrastructures. Rigorous image interpretation criteria applied to the interpretation of remote sensing images can be a valuable tool to derive information on landslide spatial and temporal distribution. However, it only allows to broadly estimate the relative age of landslides based on their morphologic signature. In this work, we investigate the topological relations between landslides and archaeological sites for nine selected settlements in the Moldavian Plateau, situated on ridges and hillslopes. Landslides and sites were mapped using high resolution LIDAR DEMs and extensive field validation activities. Landslides were classified as very old (relict), old, and recent, according to their morphologic appearance. We argue the possibility of (i) assigning a relative age to the three main classes of landslides as they appear on the present day topography, and (ii) assessing the landslide activity during the Holocene. Using this information, we set up a model of landslide evolution during the Holocene for the Moldavian Plateau, NE Romania. Analysis of the landslide inventories revealed decreasing landslide size over time, and newer landslides tend to occur as reactivations of older landslides, partly remobilizing their deposits, and mostly causing retreat of their escarpments. Analysis of the spatial relationships of the archaeological sites with the landslide inventories revealed that the settlers exploited the natural inaccessible decametric escarpments of very old landslides as defensive measures, whereas retrogressive reactivation of such older

    At the national level, the issue of wildfire monitoring represents a long debated topic. However, in the present situation, fire management requires various improvements in terms of detection, monitoring and post-fire analysis. The objectives of this study are to validate the data provided by MODIS (Terra and Aqua) Active Fire Monitoring and SEVIRI (MSG) FIR (Active Fire Monitoring) satellite products, with wildfires field data from The Romanian General Inspectorate for Emergency Situations (IGSU) (1), to chart the efficiency of satellite products in locating fires and study their strengths and weaknesses using a SWOT analysis (2). This is the initial step of a larger project that aims to implement an online Geographic Information System for fire management that will ease wildfire data manipulation and facilitate the decision making process. In order to do so, the current study objectives must be achieved. Our general strategy is to determine the consistency of direct (field measurements) and indirect (satellite data) observations. Depending on the amount of field information, the fire characteristics (location, frequency, extension area, moment of occurrence, type of fire, and others) will be studied through a statistical analysis. The products show some peculiar restrictiveness like spatial and temporal resolution. Specifically, we will process and interpret satellite products to identify wildfires according to the data from IGSU using specialized software. The case study for the application of these procedures is a set of fire events from Arad county - Romania, that occurred between 2007 and 2013. In order to do so, it is important to compare results from different sensors with field information through various methods and to use only consistent results. The results will play an important role in achieving the above mentioned informational system, which will integrate field information, satellite data and values of parameters that influence the evolution of

    Vulnerability assessment frequently emphasizes the internal fragility of a system in relation to a given hazard, when compared to similar systems or to a reference standard. This internal fragility, either biophysical or structural, may affect the ability to predict, to prepare for and cope with or to recover from the manifestation of a risk phenomenon. Thus, the vulnerability is highly related to resilience and adaptability. There is no single methodology for vulnerability and resilience analysis, their assessment can only be made by identifying and integrating indicators which are compatible with the analysis level and the geographic, economic and social features of a certain area. An integrated model of evaluating vulnerability and resilience capacity is being proposed in this paper for Targu Ocna, a small mining settlement in the Eastern Carpathians of Romania, that became in the last years a tourist town and acts within the surrounding territory as a dynamic local pole. Methodologically, the following steps and operations were considered: identifying potential hazards, identifying elements at risk, identifying proper indicators and integrating them in order to evaluate the general vulnerability and resilience. The inventory of elements at risk (the number of people potentially affected, residential or other functionalities buildings, roads and other infrastructure elements etc.) was made based on General Urban Plan, topographic maps (scale 1:5000), ortophotos from 2003 and 2008 and field mapping and researches. Further on, several vulnerability indicators were identified and included within the analytical approach: dependency ratio, income, quality of the habitat and technical urban facilities, environment quality showing differentiated sensitivity. Issues such as preparedness and preventive measures (priority areas within the risk prevention plans), coping ability (networks' geometry and connectivity, emergency utilities and services accessibility) and the

    Vulnerability assessment aims, most frequently, to emphasize internal fragility of a system comparing to a reference standard, to similar systems or in relation to a given hazard. Internal fragility, either biophysical or structural, may affect the capacity to predict, to prepare for, to cope with or to recover from a disaster. Thus, vulnerability is linked to resilience and adaptive capacity. From local level to global one, vulnerability factors and corresponding indicators are different and their significance must be tested and validated in a well-structured conceptual and methodological framework. In this paper, the authors aim to show the real vulnerability of rural settlements in Eastern Romania in a multi-level approach. The research area, Tutova Hills, counts about 3421 sq.km and more than 200.000 inhabitants in 421 villages characterized by deficient accessibility, lack of endowments, subsistential agriculture, high pressure on natural environment (especially on forest and soil resources), poverty and aging process of population. Factors that could influence the vulnerability of these rural settlements have been inventoried and assigned into groups through a cluster analysis: habitat and technical urban facilities, infrastructure, economical, social and demographical indicators, environment quality, management of emergency situations etc. Firstly, the main difficulty was to convert qualitative variable in quantitative indicators and to standardize all values to make possible mathematical and statistical processing of data. Secondly, the great variability of vulnerability factors, their different measuring units and their high amplitude of variation require different method of standardization in order to obtain values between zero (minimum vulnerability) and one (maximum vulnerability). Final vulnerability indicators were selected and integrated in a general scheme, according to their significance resulted from an appropriate factor analysis: linear and

    Seismic hazard in Romania is dominated by the Vrancea intermediate-depth events. In the same time, at local scale the hazard generated by the superficial sources can not be neglected. An important zone affected by crustal earthquakes is Fagaras-Campulung seismic area where at least once per century are reported effects of VIII+ and/or IX MSK. In order to mitigate the seismic risk of the vulnerable man-made structures (bridges, large dams), we are investigating the local effects at certain sites in this mountainous area. The aim of this paper is to evaluate the seismic effects induced in the local structure of the Fagaras-Campulung area. A complex geotectonic and physical-lithological analysis has been carried out for the area of interest, which has the geographical limits between 45.0 - 46.00 North latitude and 24.00 - 25.80 East longitude. Seismicity of the area is presented with a history of seismic activity, majority of events are 2-3 MW but there are also some greater ones (28 seismic events with magnitude greater than 3.9 MW took place between years 1517-2008). Also is presented the hypocentral distribution of seismic events function of depths, where the majority of sources (~ 1070) are at depths no more than 20km. We present the epicenters distribution on a topographic surface, together with focal mechanisms of the events. As a consequence, three seismic scenarios are taken into account to evaluate the expected accelerations and local soil response for Fagaras-Campulung zone. There are presented accelerations and response spectra (with 3 damping 5%, 10% and 20%) at Campulung-Muscel bedrock. Nonlinear effects induced by significant deformations need a certain approximated method - linear equivalent - for a multistratified zone as we considered for the Fagaras-Campulung superficial areas. Therefore important nonlinear variations of shear modulus and damping functions with state of strain during earthquakes were evidenced in superficial soils. The obtained

    We present two stable isotope records of climate variability from stalagmites in northern (#1152 from Pestera Izvorul Tausoarelor, Rodna Mountains) and south-western (#POM1 from Pestera Ascunsa, Mehedinti Mountains) Romania. Both cave entrances are located at over 1000 m asl in areas covered by mature beech forests, in continental temperate climate. Superimposed on the present-day climatic conditions are two different climate influences: Atlantic in the north and sub-mediterranean in the south-west. Both stalagmites were dated by means of uranium series on a Thermo Neptune MC-ICP-MS at Centro Nacional de Investigacion sobre la Evolucion Humana (Burgos, Spain) and samples for stable O and C stable isotopes were analysed on a Thermo Delta V IRMS at the Stable Isotope Laboratory, University of South Florida. For the stable isotopes profile, stalagmite 1152 was sampled at an average interval of 100 years , whereas POM1 was sampled at a 30 years interval. The two stalagmites reveal differences in isotopic signature response to climatic variability. When the POM1 δ18O profile is compared to the NGRIP δ18O, a lower variability of its values is evident. Even so, we are still able to distinguish structures similar to Greenland Interstadials (GIs) 7 and 8, the latter being composed of two distinct units. The stalagmite 1152 δ18O profile shows less variability although some of the peaks in the values could be correlated to GIs 4 through 12. The absolute values of these two records vary around an average of -7.5%, very close to the typical Holocene values from this part of Europe. This may point to an enhanced Mediterranean circulation towards the north during MIS 3. In return, the δ13C values of the two stalagmites are very different and point to large differences in the activity of plants and soil organisms. POM1 values, averaging -5 to -6%, indicate a C4 type vegetation in the area above the cave, that could belong to alpine meadows. This may document a lowering of the

    The Ikeda, Parker, and Sawai river meandering model is reexamined using a physical approach employing an explicit equation of motion. For periodic river shapes as seen from above, a cross-stream surface elevation gradient creates a velocity shear that is responsible for the decay of small-wavelength meander bends, whereas secondary currents in the plane perpendicular to the downstream direction are responsible for the growth of large-wavelength bends. A decay length D=H/2C(f) involving the river depth H and the friction coefficient C(f) sets the scale for meandering, giving the downstream distance required for the fluid velocity profile to recover from changes in the channel curvature. Using this length scale and a time scale T, we explicitly trace the observed length scale invariance to the equations of motion, and predict similar time and velocity scale invariances. A general time-dependent nonlinear modal analysis for periodic rivers reveals that modes higher than the third mode are needed to describe upstream migration of bend apexes just before oxbow cutoff, and are important to accurate calculations of the time and sinuosity at cutoff.

    By which physical mechanisms does a river select its shape and size? We investigate this question using small laboratory rivers formed by laminar flows.In its simplest form, this experiment consists in a flow of glycerol over a uniform layer of plastic sediments. After a few hours, a channel forms spontaneously, and eventually reaches a stable geometry. This equilibrium state corresponds accurately to the force balance proposed by Henderson (1961).If we impose a sediment discharge at the inlet of the experiment, the river adjusts to this boundary condition by widening its channel. Observation suggests that this new equilibrium results from the balance between gravity, which pulls the entrained grains towards the center of the channel, and bedload diffusion, which returns them towards the banks. This balance explains why experimental rivers get wider and shallower as their sediment load increases.However, to test quantitatively this theory against observation, we need to evaluate independently the effect of transverse slope on bedload transport. We propose to use an instability generated by bedload diffusion to do so.
