Sample records for romania soil stabilisation




    Full Text Available This paper assesses the stabilizing effect of powdered glass on clay soil. Broken waste glass was collected and ground into powder form suitable for addition to the clay soil in varying proportions namely 1%, 2%, 5%, 10% and 15% along with 15% cement (base by weight of the soil sample throughout. Consequently, the moisture content, specific gravity, particle size distribution and Atterberg limits tests were carried out to classify the soil using the ASSHTO classification system. Based on the results, the soil sample obtained corresponded to Group A-6 soils identified as ‘fair to poor’ soil type in terms of use as drainage and subgrade material. This justified stabilisation of the soil. Thereafter, compaction, California bearing ratio (CBR and direct shear tests were carried out on the soil with and without the addition of the powdered glass. The results showed improvement in the maximum dry density values on addition of the powdered glass and with corresponding gradual increase up to 5% glass powder content after which it started to decrease at 10% and 15% powdered glass content. The highest CBR values of 14.90% and 112.91% were obtained at 5% glass powder content and 5mm penetration for both the unsoaked and soaked treated samples respectively. The maximum cohesion and angle of internal friction values of 17.0 and 15.0 respectively were obtained at 10% glass powder content.

    Ashish Kumar Pathak


    Full Text Available Stabilisation is a broad sense for the various methods employed and modifying the properties of a soil to improve its engineering performance and used for a variety of engineering works. In today‟s day soil stabilisation is the major problem for civil engineers, either for construction of road and also for increasing the strength or stability of soil and reduces the construction cost. In this thesis the soil are stabilised by ground granulated blast furnace slag (GGBS and this material is obtained from the blast furnace of cement plant, which is the byproduct of iron (from ACC plant, sindri. It is generally obtained in three shaped one is air cooled, foamed shaped and another is in granulated shaped. The use of by-product materials for stabilisation has environmental and economic benefits. Ground granulated blast furnace slag (GGBS material is used in the current work to stabilise soil (clay. The main objectives of this research were to investigate the effect of GGBS on the engineering property (optimum moisture content and maximum dry density, plastic limit, liquid limit, compaction, unconfined compressive strength, triaxial and California bearing ratio test of the soil and determine the engineering properties of the stabilised.

    Full Text Available The object of this paper is to investigate the effect of adding different chloride compounds including (NaCl, MgCl2, CaCl2 on the engineering properties of silty clay soil. Various amounts of salts (2%, 4%, and 8% were added to the soil to study the effect of salts on the compaction characteristics, consistency limits and compressive strength. The main findings of this study were that the increase in the percentage of each of the chloride compounds increased the maximum dry density and decrease the optimum moisture content. The liquid limit, plastic limit and plasticity index decreased with the increase in salt content. The unconfinedcompressive strength increased as the salt content increased.

  5. Alleviation of Soil Acidity and Aluminium Phytotoxicity in Acid Soils by Using Alkaline-Stabilised Biosolids


    A pot experiment was carried out to study alleviation of soil acidity and Al toxicity by applying an alkaline-stabilised sewage sludge product (biosolids) to an acid clay sandy loam (pH 5.7) and a strongly acid sandy loam (pH 4.5). Barley (Hordeum vulgare L. cv. Forrester) was used as a test crop and was grown in the sewage sludge-amended (33.5 t sludge DM ha-1) and unamended soils. The results showed that the alkaline biosloids increased soil pH from 5.7 to 6.9 for the clay sandy loam and from 4.5 to 6.0 for the sandy loam. The sludge product decreased KCl-extractable Al from 0.1 to 0.0 cmol kg-1 for the former soil and from 4.0 to 0.1 cmol kg-1 for the latter soil. As a result, barley plants grew much better and grain yield increased greatly in the amended treatments compared with the unamended controls. These observations indicate that alkaline-stabilised biosolids can be used as a liming material for remedying Al phytotoxicity in strongly acid soils by increasing soil pH and lowering Al bioavailability.

    Full Text Available This paper aims to achieve the pentagon analysis of macroeconomic stabilization in Romania, Czech Republic and Hungary in the period 2000 to 2013. It is a comparative analysis of the countries above mentioned in terms of the five key targets of economic policy, aiming the increasing, dynamic balance of each economy: economic growth rate, unemployment rate, inflation rate, the budget deficit as a percentage of Gross Domestic Product, the current account deficit of the balance of payments as a percentage of Gross Domestic Product. The main objective of each economy which passes from planned to market economy should be to cease the economic decline, followed by the elimination of internal and external imbalances and only after that it should be followed by a continuous growth process. All the above mentioned indicators shall be represented on an ad hoc graduated scale. The period of research was chosen so as to obtain a view of the macroeconomic policies in transition from one period to another, in order to highlight the common as well as the main differences in the approach used for economy stabilization. Therefore I have computed the graphical analysis of macroeconomic stabilization pentagon for the three countries in the period 2000- 2013 to captures the dynamics of the economic policy mix. This benchmark tool shows the interdependence which exists between inflation and other important economic indicators. The events occurred in the period starting with 2007/2008 have raised the interest of economics researchers, highlighting the need for significant improvements in the surveillance of the economic and financial system. The global fragility generated concerns regarding the vulnerabilities and causes which led to the occurrence of such events, thus generating different measurement techniques. Despite all its advantages, this approach has a significant limitation consisting in the fact that it can only reveal a picture without surprising other

  8. The effect of environmental conditions and soil physicochemistry on phosphate stabilisation of Pb in shooting range soils.

    Sanderson, Peter; Naidu, Ravi; Bolan, Nanthi


    The stabilisation of Pb in the soil by phosphate is influenced by environmental conditions and physicochemical properties of the soils to which it is applied. Stabilisation of Pb by phosphate was examined in four soils under different environmental conditions. The effect of soil moisture and temperature on stabilisation of Pb by phosphate was examined by measurement of water extractable and bioaccessible Pb, sequential fractionation and X-ray absorption spectroscopy. The addition of humic acid, ammonium nitrate and chloride was also examined for inhibition or improvement of Pb stability with phosphate treatment. The effect of moisture level varied between soils. In soil MB and DA a soil moisture level of 50% water holding capacity was sufficient to maximise stabilisation of Pb, but in soil TV and PE reduction in bioaccessible Pb was inhibited at this moisture level. Providing moisture at twice the soil water holding capacity did not enhance the effect of phosphate on Pb stabilisation. The difference of Pb stability as a result of incubating phosphate treated soils at 18 °C and 37 °C was relatively small. However wet-dry cycles decreased the effectiveness of phosphate treatment. The reduction in bioaccessible Pb obtained was between 20 and 40% with the most optimal treatment conditions. The reduction in water extractable Pb by phosphate was substantial regardless of incubation conditions and the effect of different temperature and soil moisture regimes was not significant. Selective sequential extraction showed phosphate treatment converted Pb in fraction 1 (exchangeable, acid and water soluble) to fraction 2 (reducible). There were small difference in fraction 4 (residual) Pb and fraction 1 as a result of treatment conditions. X-ray absorption spectroscopy of stabilised PE soil revealed small differences in Pb speciation under varying soil moisture and temperature treatments. The addition of humic acid and chloride produced the greatest effect on Pb speciation in

  9. Validation and Upscaling of Soil Moisture Satellite Products in Romania

    Sandric, I.; Diamandi, A.; Oana, N.; Saizu, D.; Vasile, C.; Lucaschi, B.


    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

  10. Arsenic and copper stabilisation in a contaminated soil by coal fly ash and green waste compost.

    Tsang, Daniel C W; Yip, Alex C K; Olds, William E; Weber, Paul A


    In situ metal stabilisation by amendments has been demonstrated as an appealing low-cost remediation strategy for contaminated soil. This study investigated the short-term leaching behaviour and long-term stability of As and Cu in soil amended with coal fly ash and/or green waste compost. Locally abundant inorganic (limestone and bentonite) and carbonaceous (lignite) resources were also studied for comparison. Column leaching experiments revealed that coal fly ash outperformed limestone and bentonite amendments for As stabilisation. It also maintained the As stability under continuous leaching of acidic solution, which was potentially attributed to high-affinity adsorption, co-precipitation, and pozzolanic reaction of coal fly ash. However, Cu leaching in the column experiments could not be mitigated by any of these inorganic amendments, suggesting the need for co-addition of carbonaceous materials that provides strong chelation with oxygen-containing functional groups for Cu stabilisation. Green waste compost suppressed the Cu leaching more effectively than lignite due to the difference in chemical composition and dissolved organic matter. After 9-month soil incubation, coal fly ash was able to minimise the concentrations of As and Cu in the soil solution without the addition of carbonaceous materials. Nevertheless, leachability tests suggested that the provision of green waste compost and lignite augmented the simultaneous reduction of As and Cu leachability in a fairly aggressive leaching environment. These results highlight the importance of assessing stability and remobilisation of sequestered metals under varying environmental conditions for ensuring a plausible and enduring soil stabilisation.

    Full Text Available Selenium mobility in soil depends on a multitude of physical and chemical factors. The present paper highlights the selenium solubilization degree out of the total soil content in relation with its agrochemical properties. Soils samples were considered collected from different agricultural areas of the Country, with or without certain natural handicaps, from soils under industrial impact and long term agrochemical experiments. The selenium solubilization percentages out of the soil total content ranged between 3.57 and 8.15%. No solubilization percentage was calculated for Central and Southern Dobrudja and the South-Eastern Romanian Plane, because the total selenium quantities in these areas are lower and mobile selenium values are very low. The statistical analysis of the calculated percentage values highlighted homogeneous areas and areas with a higher scattering degree. Thus, in agricultural land, in acknowledged agrarian areas and in long term agricultural experiments, the percentage values are better grouped, showing (expectable soil homogeneousness, on one hand, and a significant soil selenium supply and its adequate solubilization for plant nutrition, on the other. The most scattered values occurred in the Călmăţui and Buzău valleys area in halomorphic soils, and in the Făgăraş Depression which is under the industrial polluting influence of chemical works. Among the causes for these differences is the uniformity or non-uniformity of the terrains, induced by land use and the existence or not of a handicap (polluting impact or halomorphic soils, for example. In general, there are no significant differences between the selenium mobility values and their grouping or scattering degree in the soil depth. A single exception stands out, namely in the Făgăraş Depression, where the selenium solubilization degree tends to increase with soil depth, as well as the scattering degree. In the Danube Delta diked areas Sireasa and Pardina very

  12. Geotechnical properties of peat soil stabilised with shredded waste tyre chips

    M.A. Rahgozar


    Full Text Available To accommodate major civil engineering projects in or in the vicinity of peatlands, it is essential to stabilise peat deposits. On the other hand, the accumulation of waste tyres in recent decades has caused environmental problems around the world. An effective remedy for both issues is to use scrap tyre material to stabilise problematic peat soils. This article reports an experimental investigation of the effects of adding shredded tyre chips on the stability and bearing capacity of peat soil. Peat soil samples from the Chaghakhor Wetland (Chaharmahal and Bakhtiari Province, Iran were mixed with sand at a constant dosage of 400 kg m-3 and different percentages (0 %, 5 %, 10 %, 15 % and 20 % by weight of shredded tyre chips. The unconfined compressive strength, effective cohesion, angle of internal friction and coefficient of permeability were measured for all of these mixtures. The results showed that adding shredded tyre chips significantly improved the geotechnical properties of the peat soil. The mixture with 10 % shredded tyre chips showed the highest unconfined compressive strength; the one with 15 % tyre chips exhibited the highest ductility; and adding 20 % shredded tyre chips provided the highest values for angle of internal friction, effective cohesion and coefficient of permeability. Scanning Electron Micrographs (SEM showed that the pore spaces in the stabilised peat were mostly filled with sand.

  13. The use of biogas plant fermentation residue for the stabilisation of toxic metals in agricultural soils

    Geršl, Milan; Šotnar, Martin; Mareček, Jan; Vítěz, Tomáš; Koutný, Tomáš; Kleinová, Jana


    Our department has been paying attention to different methods of soil decontamination, including the in situ stabilisation. Possible reagents to control the toxic metals mobility in soils include a fermentation residue (FR) from a biogas plant. Referred to as digestate, it is a product of anaerobic decomposition taking place in such facilities. The fermentation residue is applied to soils as a fertiliser. A new way of its use is the in situ stabilisation of toxic metals in soils. Testing the stabilisation of toxic metals made use of real soil samples sourced from five agriculturally used areas of the Czech Republic with 3 soil samples taken from sites contaminated with Cu, Pb and Zn and 2 samples collected at sites of natural occurrence of Cu, Pb and Zn ores. All the samples were analysed using the sequential extraction procedure (BCR) (determine the type of Cu, Pb and Zn bonds). Stabilisation of toxic metals was tested in five soil samples by adding reagents as follows: dolomite, slaked lime, goethite, compost and fermentation residue. A single reagent was added at three different concentrations. In the wet state with the added reagents, the samples were left for seven days, shaken twice per day. After seven days, metal extraction was carried out: samples of 10 g soil were shaken for 2 h in a solution of 0.1M NH4NO3 at a 1:2.5 (, centrifuged for 15 min at 5,000 rpm and then filtered through PTFE 0.45 μm mesh filters. The extracts were analysed by ICP-OES. Copper The best reduction of Cu concentration in the extract was obtained at each of the tested sites by adding dolomite (10 g soil + 0.3 g dolomite). The concentration of Cu in the leachate decreased to 2.1-18.4% compare with the leachate without addition. Similar results were also shown for the addition of fermentation residue (10 g soil + 1 g FR). The Cu concentration in the leachate decreased to 16.7-26.8% compared with the leachate without addition. Lead The best results were achieved by adding

  14. Ecotoxicity of chemically stabilised metal(loid)s in shooting range soils.

    Sanderson, Peter; Naidu, Ravi; Bolan, Nanthi


    Five chemical amendments (soft rock phosphate, lime, commercial phosphate amendment, red mud and magnesium oxide) were applied across four different shooting range soils to chemically stabilise metal(loid)s in the soils. Soils were contaminated with Pb between 2330 and 12,167 mg/kg, Sb from 7.4 to 325 mg/kg and soil pH ranged from 5.43 to 9.29. Amendments were tested for their ability to reduce the bioavailability of Pb, Sb, Zn, Ni, Cu and As in the soils to soil organisms after one year of aging, by measuring a series of ecotoxicological endpoints for earthworms and plants and soil microbial activity. Growth-based endpoints for earthworms and plants were not significantly affected by amendment addition, except in the most contaminated soil. Per cent survival and weight-loss reduction of earthworms was enhanced by amendment addition in only the most contaminated soil. Plant biomass and root elongation was not significantly affected by amendment addition (p=alkaline pH (9-12). Lead in soil organisms was relatively low despite the high concentrations of Pb in the soils, suggesting low bioavailability of Pb. Uptake of Pb by earthworms was reduced by between 40 and 96 per cent by amendments, but not across all soils. Amendments reduced Sb in earthworms in Townsville soil by up to 92 per cent. For lettuce the average uptake of Pb was reduced by 40 to 70 per cent with amendment addition in Townsville, Darwin and Perth soil. The effect of amendments on the uptake of Sb, Zn, Ni, Cu and As was variable between soils and amendments. Microbial activity was increased by greater than 50 per cent with amendments addition, with soft rock phosphate and lime being the most effective in Murray Bridge and TV soils and commercial phosphate and MgO being the most effective in Darwin and Perth soils.

  15. Chemical stabilisation of lead in shooting range soils with phosphate and magnesium oxide: Synchrotron investigation.

    Sanderson, Peter; Naidu, Ravi; Bolan, Nanthi; Lim, Jung Eun; Ok, Yong Sik


    Three Australian shooting range soils were treated with phosphate and magnesium oxide, or a combination of both to chemically stabilize Pb. Lead speciation was determined after 1 month ageing by X-ray absorption spectroscopy combined with linear combination fitting in control and treated soils. The predominant Pb species in untreated soils were iron oxide bound Pb, humic acid bound Pb and the mineral litharge. Treatment with phosphate resulted in substantial pyromorphite formation in two of the soils (TV and PE), accounting for up to 38% of Pb species present, despite the addition of excess phosphate. In MgO treated soils only, up to 43% of Pb was associated with MgO. Litharge and Pb hydroxide also formed as a result of MgO addition in the soils. Application of MgO after P treatment increased hydroxypyromorphite/pyromorphite formation relative to soils teated with phosphate only. X-ray diffraction and Scanning electron microscopy revealed PbO precipitate on the surface of MgO. Soil pH, (5.3-9.3) was an important parameter, as was the solubility of existing Pb species. The use of direct means of determination of the stabilisation of metals such as by X-ray absorption spectroscopy is desirable, particularly in relation to understanding long term stability of the immobilised contaminants.

  16. Use of Coal Bottom Ash as Mechanical Stabiliser in Subgrade Soil

    Abdus Salaam Cadersa


    Full Text Available This paper presents the laboratory investigation work which forms part of a full scale research road project in Mauritius where coal bottom ash is used as mechanical stabiliser in a saprolitic subgrade soil. Three mixtures of subgrade soil and CBA were investigated in the laboratory, each containing varying percentages of coal bottom ash by weight (15%, 30%, and 40%, resp.. The laboratory research indicated that the mechanical properties of the subgrade soil are improved with the addition of bottom ash. Highest values for soaked and unsoaked CBR values were obtained for the mixture containing 30% by weight of bottom ash, which were 145% and 95%, respectively, as compared to 40% and 55% for the subgrade soil alone. Upon addition of coal bottom ash, a considerable decrease in swelling potential during soaking was observed for the mixture containing 40% by weight of CBA. The swell decreased from 0.17% for the subgrade soil alone to 0.04% for the mixture containing 40% by weight of CBA. Moreover, a CBA content of 30% resulted in a mix of intermediate plasticity as compared to the subgrade soil which is highly plastic. It is concluded that coal bottom ash can be used successfully as a mechanical stabilizer in the experimental subgrade soil by addition of 30 to 40% of CBA.

  17. Effect of Alkaline-Stabilised Sewage Sludge on Extractable Organic Carbon and Copper in Soils


    An incubation experiment was conducted to evaluate the potential for water contamination with sludgederived organic substances and copper following land application of alkaline-stabilised sewage sludge. Two contrasting sludge-amended soils were studied. Both soils were previously treated with urban and rural alkaline biosolids separately at sludge application rates of 0, 30 and 120 t ha-1 fresh product. The air-dried soil/sludge mixtures were wetted with distilled water, maintained at 40 % of water-holding capacity and equilibrated for three weeks at 4 ℃ before extraction. Subsamples were extracted with either distilled water or 0.5 mol L-1 K2SO4 solution. The concentrations of organic C in the aqueous and chemical extracts were determined directly with a total organic carbon (TOC) analyser. The concentrations of Cu in the two extracts were also determined by atomic absorption spectrophotometry. The relationship between the two extractable organic C fractions was examined, together with that between extractable organic C concentration and extractable Cu concentration. Application of alkaline biosolids increased the concentrations of soil mobile organic substances and Cu. The results are discussed in terms of a possible increase in the potential for leaching of sludge-derived organics and Cu in the sludge-amended soils

  19. Recycling vs. stabilisation of soil sugars - a long-term laboratory incubation experiment

    Basler, A.; Dippold, M.; Helfrich, M.; Dyckmans, J.


    Independent of its chemical structure carbon (C) persists in soil for several decades, controlled by stabilisation and recycling. To disentangle the importance of the two factors on the turnover dynamics of soil sugars, an important compound of soil organic matter (SOM), a three year incubation experiment was conducted on a silty loam soil under different types of land use (arable land, grassland and forest) by adding 13C-labeled glucose. The compound specific isotope analysis of soil sugars was used to examine the dynamics of different sugars during incubation. Sugar dynamics were dominated by a pool of high mean residence times (MRT) indicating that recycling plays an important role for sugars. However, this was not substantially affected by soil C content. Six months after label addition the contribution of the label was much higher for microbial biomass than for CO2 production for all examined soils, corroborating that substrate recycling was very effective within the microbial biomass. Two different patterns of tracer dynamics could be identified for different sugars: while fucose (fuc) and mannose (man) showed highest label contribution at the beginning of the incubation with a subsequent slow decline, galactose (gal) and rhamnose (rha) were characterised by slow label incorporation with subsequently constant levels, which indicates that recycling is dominating the dynamics of these sugars. This may correspond to (a) different microbial growing strategies (r and K-strategist) or (b) location within or outside the cell membrane (lipopolysaccharides vs. exopolysaccharides) and thus be subject of different re-use within the microbial food web. Our results show how the microbial community recycles substrate very effectively and that high losses of substrate only occur during initial stages after substrate addition.

    This study was conducted to identify the principle selenate carrier phases for two selected soils, by comparing their reactivity with selenate to that of pure phases of the solids. Silica, calcium carbonate, aluminium hydroxide, goethite, bentonite and humic acid were selected as the main soil carrier phases. Comparisons were made first on the parameter values obtained with the best fit of a kinetic sorption model which can discriminate instantaneous sorption from kinetically limited sorption. Then comparisons were made of the ability for each solid to stabilise selenate by measuring the ratio of the partition coefficient for sorption (Kd{sub sorption}) over that of the desorption (Kd{sub desorption}). Kinetics and stabilisation were used to help elucidate the nature of interactions with the test solid phases for a large range of selenate concentrations. The experiments were conducted over 165 h in batch reactors, the solid being isolated from the solution by dialysis tubing, at two pH (5.4 and 8) and three selenate concentrations (1 x 10{sup -3}, 1 x 10{sup -6} and 1 x 10{sup -8} mol L{sup -1}). The results obtained showed that only aluminium hydroxide can sorb selenate throughout the studied pH range (pH 5.4 to 8.0). The sorption capacity on this mineral was high (Kd{sub sorption} > 100 to 1 x 10{sup 4} L kg{sup -1}) and the selenate was mainly stabilized by the formation of inner sphere complexes. The sorption on goethite occurred at pH 5.4 (Kd{sub sorption} 52 L kg{sup -1}), mainly as outer sphere complexes, and was null at pH 8. On silica, a weak sorption was observed only at pH 5.4 and at 165 h (Kd{sub sorption} 4 L kg{sup -1}). On bentonite, calcium carbonate and humic acid no significant sorption was observed. Concerning the two soils studied, different behaviours were observed for selenate. For soil Ro (pH 5.4), Kd{sub sorption} was low (8 L kg{sup -1}) compared to soil Bu (pH 8) (70 L kg{sup -1}). The sorption behaviour of selenate on soil Ro was mainly

    Full Text Available Being a common and finite resource, soil - as a natural and very complex ecosystem, is essential to human society. Inseveral regions of Europe, including Romania too, soil resources are degraded due to different causes, or, sometimes,irreversibly lost, mainly due to erosion, decline in organic matter or contamination. As regard to soil erosion only, inRomania, about 42% of the total agricultural lands are affected by water erosion in different forms and intensities.Soil degradation has negative impacts on other areas also, not only in-site but also off-site, areas which are alsoconsidered of common interest for the people (e.g. air and water quality, biodiversity and climate change. Costs torestore such a damages and environmental quality in general may be very high and thus preferable to be avoided.To maintain and/or improve a good quality of the soils for a long period of time, there needed to be implemented inRomania , as much as possible, some agri-environmental schemes, according to the current EU models and policies, inparticular, through the Common Agricultural Policy (CAP.The paper briefly presents and analyzes such agri-environmental schemes developed for the agricultural lands from thehilly areas in Romania that is very affected by water erosion and landslides – the Curvature zone of Sub-Carpathians.The schemes, developed within the Research Station for Soil Erosion and Conservation Aldeni-Buzau, which belongs tothe University of Agricultural Sciences in Bucharest, is based on friendly agricultural practices to be implemented onagricultural lands located on slopes. Also, the new conceptual European model, known as Driving Forces-Pressures-State-Impacts-Responces (DPSIR, adapted for the soil erosion impact assesment on environment, will be herepresented, in order to be promoted and used on a large scale in Romania as well.

  2. Three-year performance of in-situ mass stabilised contaminated site soils using MgO-bearing binders.

    Wang, Fei; Jin, Fei; Shen, Zhengtao; Al-Tabbaa, Abir


    This paper provides physical and chemical performances of mass stabilised organic and inorganic contaminated site soils using a new group of MgO-bearing binders over 3 years and evaluated the time-dependent performance during the 3 years. This study took place at a contaminated site in Castleford, UK in 2011, where MgO, ground granulated blastfurnace slag (GGBS) and Portland cement (PC) were mixed with the contaminated soils in a dry form using the ALLU mass mixing equipment. Soil cores were retrieved 40-day, 1-year and 3-year after the treatment. The core quality, strength, and the leaching properties were determined via physical observation, unconfined compressive strength (UCS) and batch leaching tests. After 3-year treatment, the UCS values of ALLU mixes were in the range of 50-250kPa; the leachate concentrations of Cd, Pb, Cu and Zn (except Ni) in all mixes were lower than their drinking water standards; and the leachability of total organics was in the range of 10-105mg/L. No apparent degradation of the mass stabilised materials after 3 years' exposure to the field conditions was found. MgO-GGBS blends were found able to provide higher strength and less leachability of contaminants compared to PC and MgO-only mixes in mass stabilised soils.

  3. Soil stabilisation using AMD sludge, compost and lignite: TCLP leachability and continuous acid leaching.

    Tsang, Daniel C W; Olds, William E; Weber, Paul A; Yip, Alex C K


    Utilising locally available industrial by-products for in situ metal stabilisation presents a low-cost remediation approach for contaminated soil. This study explored the potential use of inorganic (acid mine drainage (AMD) sludge and zero-valent iron) and carbonaceous materials (green waste compost, manure compost, and lignite) for minimising the environmental risks of As and Cu at a timber treatment site. After 9-month soil incubation, significant sequestration of As and Cu in soil solution was accomplished by AMD sludge, on which adsorption and co-precipitation could take place. The efficacy of AMD sludge was comparable to that of zero-valent iron. There was marginal benefit of adding carbonaceous materials. However, in a moderately aggressive environment (Toxicity Characteristic Leaching Procedure), AMD sludge only suppressed the leachability of As but not Cu. Therefore, the provision of compost and lignite augmented the simultaneous reduction of Cu leachability, probably via surface complexation with oxygen-containing functional groups. Under continuous acid leaching in column experiments, combined application of AMD sludge with compost proved more effective than AMD sludge with lignite. This was possibly attributed to the larger amount of dissolved organic matter with aromatic moieties from lignite, which may enhance Cu and As mobility. Nevertheless, care should be taken to mitigate ecological impact associated with short-term substantial Ca release and continuous release of Al at a moderate level under acid leaching. This study also articulated the engineering implications and provided recommendations for field deployment, material processing, and assessment framework to ensure an environmentally sound application of reactive materials.

  4. Geotechnical properties of peat soil stabilised with shredded waste tyre chips in combination with gypsum, lime or cement

    M. Saberian


    Full Text Available Peat has a high content of water and organic substances. These weak components can cause low bearing capacity and high consolidation settlement under load, which means that peat deposits must usually be stabilised if they are to bear constructions such as buildings or roads. In this study we investigated the performance of waste tyre chips (10 % by weight and sand (400 kg m-3 supplemented with a pozzolanic binder (gypsum, lime or cement at a range of dosages (5 %, 10 % or 15 % by weight as a stabiliser for peat soil. Peat samples were taken from a fen peatland at Chaghakhor Wetland in Chahar Mahal and Bakhtiari Province, Iran. In total, 162 test specimens were prepared and subjected to laboratory strength testing (unconfined compression test and direct shear test. Additionally, the pH of each admixture was recorded immediately after mixing, elemental compositions were determined by X-Ray Fluorescence (XRF, and structures were examined using Scanning Electron Microscopy (SEM. It was observed that: (1 the total percentage of pozzolanic compounds in the peat soil was well below the minimum of 70 % set by the standard ASTM C 618 (ASTM 2000, so an additive such as cement, lime or gypsum would certainly be required; (2 specimens stabilised with gypsum or lime showed improvements in unconfined compressive strength (UCS, but those stabilised with ordinary Portland cement exhibited the greatest improvement in UCS (up to 12,200 % as well as improvements in the direct shear parameters c and φ; (3 according to the XRF tests, additives such as cement, lime and gypsum introduced considerable amounts of Si, Al, Ca and O, which are important for pozzolanic reactions in peat soils; and (4 on the basis of the results of UCS and direct shear tests, the optimum percentage of the additives tested would be 5 %.

  5. Limiting Factors for Agricultural Production and Differentiation of Soil Management in Romania

    Ioana Moraru, Paula; Rusu, Teodor; Bogdan, Ileana; Ioan Pop, Adrian; Pop, Horia


    Romania's land area is 23,839,100 ha; 0.16% of the world's surface. Worldwide, Romania is ranked #83 for areal extent, and it consitutes 4.81% of the Europe's surface (ranked #12). Romania has 14,856,800 ha of agricultural land which represents 62.3% of the total surface; 0.65 ha per capita. At the national level, 72.5% and 27.5% of soils in Romania can be broadly classed as very poor and good/very good, respectively, based on intrinsic soil characteristics, climate, topography, and ground water. Romania has a specific geographical situation, namely: i) Romanian territory is located in the southeast portion of Central Europe at the cross roads of several high and low pressure centers that form regularly at the borders. The influence of these air masses is altered by the presence in the central regions of the Carpathian mountain chain resulting in a diverse climate with average annual rain fall amounts between 350 to 1,400 mm and average annual temperatures between 2 and 11.5°C. ii) At the national level, almost all soils in the international classification system are present in Romania; each soil type having specific properties and characteristics. iii) On approximately 12.5 million ha (7.5 million ha arable), soil fertility is adversely affected by erosion, acidity, low humus content, extreme texture (clay, sand), excessive moisture, chemical pollution etc. These natural and anthropogenic factors dramatically influence agricultural production. Furthermore, soil, climate, topography, etc. vary widely not only across the country, but also on smaller scales, even across fields within the same farm. In Steppe zone limitative climatic factors, which require differentiation towards soil management use, include: long periods of drought, high temperatures, high frequency winds (wind erosion in area of sands), low relative air humidity, and harsh frosts during winter. Negative phenomena most commonly encountered in this area are salinization, excess water, temporary

    Verma, B C; Datta, S P; Rattan, R K; Singh, A K


    The present investigation was undertaken in view of the limited information on the relative proportion of labile and stabilized fractions of soil organic carbon (SOC) in intensively cultivated lands, particularly under tropics. The specific objectives were i) to study the comparative recovery of SOC by different methods of labile carbon estimation under intensively cultivated lands and ii) to evaluate the impact of agricultural practices on carbon management index. For this purpose, in all, 105 surface soil samples were collected from intensively cultivated tube well and sewage irrigated agricultural lands. These samples were analysed for total as well as labile pools of SOC. Results indicated that Walkley and Black, KMnO4-oxidizable and microbial biomass carbon constituted the total SOC to the extent of 10.2 to 47.4, 1.66 to 23.2 and 0.30 to 5.49%, respectively with the corresponding mean values of 26.2, 9.16 and 2.15%. Lability of SOC was considerably higher in sewage irrigated soils than tube well irrigated soils under intensive cropping. Under soybean-wheat, the higher values of carbon management index (CMI) (279 and 286) were associated with the treatments where entire amount of nitrogen was supplied through FYM. Similar results were obtained under rice-wheat, whereas in case of maize-wheat the highest value of CMI was recorded under treatment receiving NPK through chemical fertilizer along with green manure. There was also a significant improvement in CMI under integrated (chemical fertilizer + organics) and chemical fertilizer-treated plots. The values of CMI ranged from 220 to 272 under cultivated lands receiving irrigation through sewage and industrial effluents.

  7. Changes in Soil Solution Cu and Zn Follogwing Application of Alkaline Stabilised Sewage Sludge and Gamma-Irradiation


    A glasshouse pot experiment was conducted to study study changes in the solubility of copper and zinc in the soil-plant system follwing heavy application of sewage sludge and partial sterilisation of the sludge/soil mixture,A silghtly acid sandy loam was mixed with alkaline stabilised and composted urban sewage sludge solids ('Agri-Soil',180 t hm-2),and the soil/sludge mixture was γ-irradiated( 10 kGy).The contrasts without the application of sewage sludge and γ-irradiation were also included in the experiment.Perennial ryegrass(Lolium perenne,cv.Magella) was grown on irradiated and unirradiated soils for 50 days. Soil solution samples were obtained using soil suction samplers immediately before plant transplantation and every ten days thereafter.The soil solution smmples were used directly for determination of Cu and Zn,together with pH,electrical conductivity(EC) and absorbance at wavelength 360 nm(A360).Application of Agri-Soil led to a substantial increase in dissolved Cu and a significant derease in dissolved Zn in the soil solution and thess effect were accompanied by increased soil solution pH ,EC and A360 ,The alkaline sludge product(Agri-Soil) in combination with γ-irradiation also led to pronounced elevtion of Cu and A360 but a marked decline in EC, indicatig an increase in dissolvedorganic compounds and a decrease in the ionic strength of the soil solution ,The dissolved Cu and Zn,EC and A360 usually decreased while the ph increased fter plant growth for 50 days.

  8. Heavy metals in soils from Baia Mare mining impacted area (Romania) and their bioavailability

    Roba, Carmen; Baciu, Calin; Rosu, Cristina; Pistea, Ioana; Ozunu, Alexandru


    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

  9. Arsenic and Antimony Content in Soil and Plants from Baia Mare Area, Romania

    Gabriela Oprea


    Full Text Available Problem statement: The objective of this research was to evaluate the degree of soil contamination with arsenic and antimony in Baia Mare, a nonferrous mining and metallurgical center located in the North West region of Romania. The soil in the area is affected by the emissions of powders containing metals from metallurgical factories. Previous studies indicated the soil contamination with copper, zinc, cadmium and lead, but there is few data about the actual level of soil pollution with arsenic and antimony. Approach: The soil samples were collected from 2 districts of Baia Mare: Ferneziu, which is located in the proximity of a lead smelter and Săsar district which is located along the Sasar River in the preferential direction of the wind over a metallurgical factory producing lead. As reference was considered Dura area located in a less polluted hilly area, in the west part of the town. Samples of soil and plants from the residential area of Ferneziu, Săsar and Dura districts were collected. The arsenic determination was carried out by inductively coupled plasma atomic emission spectrometry and the antimony determination by inductively coupled plasma mass spectrometry. Results: In Ferneziu area, the concentration of arsenic in soil ranged between 0.25 and 255 mg kg-1. In Săsar district the arsenic concentration in the soil ranged between 5.5 and 295 mg kg-1. Regarding antimony, in Ferneziu area the concentration ranged between 5.3 and 40.6 mg kg-1; while in Săsar, antimony soils concentrations vary in the range: 0.9-18.4. Arsenic and antimony concentrations in plants were low for almost of the samples, both in Ferneziu and Săsar area indicating a low mobility of these elements in the studied soils. Conclusion: This study indicated the soil pollution with arsenic both in Ferneziu district and in Săsar district. The soil pollution with antimony was found especially in Ferneziu district.

  10. Mapping soil organic carbon stock in the area of Neamtu Catchment, Northeastern Romania

    Breaban, Ana-Ioana; Bobric, Elena-Diana; Breaban, Iuliana-Gabriela; Rusu, Eugen


    The quantification of soil organic carbon stocks and its spatial extent is directly influenced by the land cover. The aim of the study is to quantify both the spatial distribution of soil organic carbon and stocks under different soil types and land uses in an area of 41.808,04 ha in northeastern part of Romania. It has been studied the evolution of carbon stocks over time, taking into account the change of land use between 1990-2012 under 5 classes: forests, pastures, arable land, orchard and built spaces. Common soils are Cambisols, Fluvisols, Phaezems, and Luvisols, forest being the predominant land use. The most important loss of soil organic carbon occurs as a result of changes in the supply of biomass supplying litter and therefore the process of bioaccumulation. The samples were collected from 100 representative soil profiles and analyzed with Analytik Jena multi N/C 2100 with HT 1300 solid module. Based on the soil organic carbon, C/N ratio and texture the values of those parameters varied from high values in Ao and Bv horizons to lower values in C horizon. In order to model soil organic carbon concentration were used different interpolation techniques (regression and ordinary -kriging, IDW) at different sampling densities for each depth to 100 cm, using a Gaussian approach to estimate the uncertainty. It is noticeable that soil organic carbon had a positive correlation with different types of land uses and a negative correlation with the elevation, being a decreasing trend of the carbon stocks sequestered in biomass, litter and soil. In the upper part of the profiles, the soil organic carbon stock considerably varied for forest land between 6.5-7.23 kg C/sqm) and agricultural land (3.67-4.65 kg C/sqm). The kriging regression evidenced a good variability of the calculated root mean square errors of the predicted soil organic carbon stocks.

  11. Three-year performance of in-situ solidified/stabilised soil using novel MgO-bearing binders.

    Jin, Fei; Wang, Fei; Al-Tabbaa, Abir


    A new group of MgO-bearing binders has been developed recently which showed improved sustainability and technical performance compared to Portland cement (PC). However, the application of these MgO-bearing binders in the Solidification/Stabilisation (S/S) techniques is very limited. This study investigates the three-year performance of a highly contaminated soil treated by in-situ S/S using MgO-bearing binders and PC. The core quality, strength, permeability and the leaching properties of the S/S materials were evaluated. The effects of binder composition, addition of inorgano-organo-clay (IOC) and the grout content on the properties of the 3-y S/S materials are discussed. It is found that although MgO alone provided negligible strength to the soil, it is superior in immobilising both inorganic and organic contaminants. Replacing MgO by ground granulated blast-furnace slag (GGBS) significantly enhanced the strength while also performed well in immobilising the contaminants. The improved pH buffering capacity was attributed to the low solubilities of brucite and hydrotalcite-like phases formed in the MgO-bearing binders, and was also the reason for the improved performance in stabilising contaminants. The addition of IOC slightly decreased the strength and the permeability of the S/S materials but inconsistent effect on the contaminant immobilisation was found depending on the binder composition. This study showed no degradation of the S/S materials after 3 y exposure to field conditions and has proved the applicability and the advantages of MgO-bearing binders over PC in S/S.

  12. Analysis of predictors related to soil contamination in recreational areas of Romania.

    Gagiu, C; Pica, E M; Querol, X; Botezan, C S


    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.

  13. GIS and RS soil-vegetation correlations for continental salt-lands habitats in NE Romania

    Dan Laurenţiu Stoica


    Full Text Available Continental saltlands have a high degree of peculiarity amongst European primary habitats and a prominent insular character. The present scientific approach establishes the degree of soil-vegetation correlation in continental slatlands patches as a measure of habitat continuity/fragmentation and soil conservation/degradation. The use of hyperspectral imagery, soil types’ distribution and vegetal associations’ conservation status reveal disturbances in relation with human induced modifications in comparison with normal plant-soil interdependence. Supervised classifications of LANDSAT satellite imagery along with detailed soil maps, ground truth data provided by accurate GPS positioning and field based plants evaluation are used to perform landscape metrics analyses. The landscape metrics approach is meant to find the balance between extent and grain in the case of saltlands habitats analyses and the degree of patches and classes inhomogeneity. These also give an insight of habitats connectivity and/or isolation in relation with land use topology and soil multiplexing. The resulting training sets developed for a representative, protected area in the county of Iaşi enhance the creation of a comprehensive mask to be used for the evaluation of larger areas in the silvan-steppes of North-Eastern Romania. The model is statistically tested to depict the degree of correlation and confidence. The final goal resides in more proper measures elaboration for the mitigation of continental saltland preservation and natural resources exploitation via agricultural and the associated activities.

  14. Stabilising metal(loid)s in soil with iron and aluminium-based products: microbial, biochemical and plant growth impact.

    Garau, Giovanni; Silvetti, Margherita; Castaldi, Paola; Mele, Elena; Deiana, Pietrino; Deiana, Salvatore


    Four iron and aluminium-based products, including red mud (RM), hematite (Fe2O3), an iron-rich water treatment residual (Fe-WTR) and amorphous Al hydroxide (Al-OH), were evaluated for their effectiveness at stabilising As and heavy metals (i.e. Cd, Cu, Pb, Zn) in a circumneutral contaminated soil [As (2105 mg kg(-1)), Cd (18 mg kg(-1)), Cu (264 mg kg(-1)), Pb (710 mg kg(-1)), Zn (522 mg kg(-1))]. Treatment impacts on soil microbial and biochemical features (i.e. microbial biomass-C, microbial counts, 16S rRNA PCR-TTGE of culturable bacteria, dehydrogenase, urease and β-glucosidase activity, Biolog derived parameters-AWCD and richness) as well as bean (Phaseolus vulgaris) and wheat (Triticum vulgare) growth were also assessed. After 6 months equilibration, all the amendments (application rate 3% w/w) but RM reduced labile As while only Al-OH reduced the concentration of water-soluble heavy metals. Despite the highest bioavailability of contaminants, most of the soil microbial and biochemical features monitored (i.e. microbial biomass-C, total bacterial counts, dehydrogenase activity and AWCD) were significantly higher in the RM-soil. Bean germination was completely inhibited in RM-soil while wheat growth was similar to that of the control. The Al-OH treatment was best overall, promoting microbial abundance, diversity and activity while increasing bean and wheat growth and reducing As accumulated in plant shoots. Results suggest that Al-OH is a suitable candidate for field evaluations while the use of RM in the remediation of circumneutral or subalkaline contaminated soils should be reconsidered.

  15. Mechanical and leaching behaviour of slag-cement and lime-activated slag stabilised/solidified contaminated soil.

    Kogbara, Reginald B; Al-Tabbaa, Abir


    Stabilisation/solidification (S/S) is an effective technique for reducing the leachability of contaminants in soils. Very few studies have investigated the use of ground granulated blast furnace slag (GGBS) for S/S treatment of contaminated soils, although it has been shown to be effective in ground improvement. This study sought to investigate the potential of GGBS activated by cement and lime for S/S treatment of a mixed contaminated soil. A sandy soil spiked with 3000mg/kg each of a cocktail of heavy metals (Cd, Ni, Zn, Cu and Pb) and 10,000mg/kg of diesel was treated with binder blends of one part hydrated lime to four parts GGBS (lime-slag), and one part cement to nine parts GGBS (slag-cement). Three binder dosages, 5, 10 and 20% (m/m) were used and contaminated soil-cement samples were compacted to their optimum water contents. The effectiveness of the treatment was assessed using unconfined compressive strength (UCS), permeability and acid neutralisation capacity (ANC) tests with determination of contaminant leachability at the different acid additions. UCS values of up to 800kPa were recorded at 28days. The lowest coefficient of permeability recorded was 5×10(-9)m/s. With up to 20% binder dosage, the leachability of the contaminants was reduced to meet relevant environmental quality standards and landfill waste acceptance criteria. The pH-dependent leachability of the metals decreased over time. The results show that GGBS activated by cement and lime would be effective in reducing the leachability of contaminants in contaminated soils. Copyright © 2011 Elsevier B.V. All rights reserved.

  16. A new low carbon cementitious binder for stabilising weak ground conditions through deep soil mixing.

    Sargent, P.; Hughes, P. N.; Rouainia, M.


    Soft alluvial soils present unfavourable conditions for engineering developments due to their poor bearing capacities and high potential for experiencing shrinkage and swelling. This paper focusses on deep dry soil mixing (DDSM), which introduces cementitious binders to soft soils via a rotating auger drill, thereby producing soil-cement columns. Ordinary Portland cement (CEM-I) is globally used across the construction industry and is the most commonly used binder for DDSM applications due to...

  17. Thermal signal propagation in soils in Romania: conductive and non-conductive processes

    C. Demetrescu


    Full Text Available Temperature data recorded in 2002 and 2003 at 10 stations out of the 70 available in the Romanian automatic weather stations network are presented and analyzed in terms of the heat transfer from air to underground. The air temperature at 2 m, the soil temperatures at 0, 5, 10, 20, 50 and 100 cm below the surface as well as rain fall and snow cover thickness have been monitored. The selected locations sample various climate environments in Romania. Preliminary analytical modelling shows that soil temperatures track air temperature variations at certain locations and, consequently, the heat transfer is by conduction, while at other stations processes such as soil freezing and/or solar radiation heating play an important part in the heat flux balance at the air/soil interface. However, the propagation of the annual thermal signal in the uppermost one meter of soil is mainly by conduction; the inferred thermal diffusivity for 8 stations with continuous time series at all depth levels ranges from 3 to 10×10−7 m2 s−1.

  18. Performance study and influence of radiation emission energy and soil contamination level on γ-radiation shielding of stabilised/solidified radionuclide-polluted soils.

    Falciglia, Pietro P; Puccio, Valentina; Romano, Stefano; Vagliasindi, Federico G A


    This work focuses on the stabilisation/solidification (S/S) of radionuclide-polluted soils at different (232)Th levels using Portland cement alone and with barite aggregates. The potential of S/S was assessed applying a full testing protocol and calculating γ-radiation shielding (γRS) index, that included the measurement of soil radioactivity before and after the S/S as a function of the emission energy and soil contamination level. The results indicate that setting processes are strongly dependent on the contaminant concentration, and for contamination level higher than 5%, setting time values longer than 72 h. The addition of barite aggregates to the cement gout leads to a slight improvement of the S/S performance in terms of durability and contaminant leaching but reduces the mechanical resistance of the treated soils samples. Barite addition also causes an increase in the γ-rays shielding properties of the S/S treatment up to about 20%. Gamma-ray measurements show that γRS strongly depends on the energy, and that the radioactivity with the contamination level was governed by a linear trend, while, γRS index does not depend on the radionuclide concentration. Results allow the calculated γRS values and those available from other experiments to be applied to hazard radioactive soil contaminations.

  19. Application of Electrokinetic Stabilisation (EKS) Method for Soft Soil: A Review

    Azhar, ATS; Azim, MAM; Syakeera, NN; Jefferson, IF; Rogers, CDF


    Soil properties such as low shear strength, excessive compression, collapsing behavior, high swell potential are some of the undesirable properties of soils in geotechnical engineering and those properties would cause severe distress to the structures. To solve these, an innovative stabilization of Electrokinetic (EKS) has been introduced. Electrokinetic is an applicable technique to transport charged particles and fluid in an electric potential. The EKS demonstrates changes in soil pH due to electrolysis reactions, water flow between the electrodes and migration of ions towards the cathode. This treatment has proven its efficiency in consolidating organic, peat and clayey silt as well as less expensive than other methods. Otherwise, this method also gives advantage by not disturbing site. The primary objective of this review is to discuss the application of electrokinetic and to investigate the current knowledge of electrokinetic in geotechnical application through a literature search and review, including consideration of certain aspects related to the soft soil application that may be relevant to the future study and at the same time addressing some key issues and their implications on soil behaviors.

  20. Spatial Soil Temperature and Moisture Monitoring Across the Transylvanian Plain, in Romania

    Rusu, Teodor; Weindorf, David; Haggard, Beatrix; Moraru, Paula Ioana; Sopterean, Mara Lucia


    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.

  1. Do iron and aluminium oxides stabilise organic matter in soil? A multi-scale statistical analysis, from field to horizon

    Moni, C.; Chabbi, A.; Nunan, N.; Rumpel, C.; Chenu, C.


    Although many "in vitro" experiments demonstrated that Fe and Al oxides stabilise organic carbon (OC) in soil, very few field studies validated that result, and none of them took into account the influence of scale and that of depth on the relationships linking OC to metal oxides in soil. In the present study, we characterised the latter as a function of depth and horizon at two different sampling scales: the field scale and the pedological pit scale. Twenty seven pits, 2 m deep, were opened over a 22 ha area. At large scale, samples were collected per horizons, whereas at fine scale, 150 positioned samples were collected over the surface of a selected profile. All samples were analysed for their content in OC, in Fe and Al oxides (amorphous Feo, Alo and crystalline Fed-o, Ald-o), and in both forms of Si associated either with amorphous or crystalline forms of metal oxides (Sio, Sid-o). For both sampling scales, relationships between OC and Feo, Alo, Sio, Fed-o, Ald-o, Sid-o were statistically investigated per whole profiles and per horizons. For whole profile at large and fine scale, results showed that all variables were correlated to OC. However, all variables, except Sio at fine scale, were also correlated with depth, suggesting that most of these correlations might only be due to a simultaneous depth dependency of correlated variables. On the contrary, within single horizons much less correlations were observed suggesting that this mode of investigation limits the confounding effects of depth. At fine scale per horizons, seven correlations independent from depth were observed in deep horizons only. Four of them were positive and implied amorphous form of Fe and Al suggesting that these oxides physically interact with OM in the subsoil, whereas the three last were negative and implied both forms of Si, suggesting that Si compete with OC for the fixation on sorption sites. In the three deepest horizons, slope coefficients of linear correlations between OC and

  2. Leachability of Arsenic (As) Contaminated Landfill Soil Stabilised by Cement and Bagasse Ash

    Azhar, A. T. S.; Azim, M. A. M.; Aziman, M.; Nabila, A. T. A.


    Contaminated soil with heavy metals, especially Arsenic (As) has become a major issue worldwide. As is reported to be a metal that affects human health and is related to have caused serious diseases that interrupts the nervous system, blood vessels and kidneys. However, proper treatment techniques such as Stabilization/Solidification (S/S) method can be employed and is capable of controlling these heavy metals from contaminating the soil strata and groundwater resources. This study is to investigate the leachability of Arsenic (As) in S/S method when bagasse ash (BA) is added to remedy contaminated Landfill soil. Cement is added at a proportion of 5%, 10%, 15% and 20% in sample weights without BA while in another sample; the cement replaces BA at a proportion of 2.5%, 5%, 7.5%. and 10%. All samples were allowed to harden and cured at room temperature for 7, 14 and 28 days. The effectiveness of the treatment was assessed by conducting Synthetic Precipitation Leaching Procedure (SPLP). Results indicate that pH and leachability are found to have major influence on metal release. The final pH after leaching tests showed improvements especially samples containing BA. In addition, the concentration of As in the SPLP test after the curing period of 28 days were detected to be below the leachability limit as regulated by WHO's Guidelines for Drinking-water Quality. As a whole, the results obtained from testing showed that sample containing 10% cement with 10% BA is the most effective and is the optimum mix since this proportion succeeded in minimising the leachability of As at total reduction by 100%, In conclusion, partial replacement of cement with BA in the binder system has been successful in reducing the leachability.

  3. Solidification/stabilisation of metals contaminated industrial soil from former Zn smelter in Celje, Slovenia, using cement as a hydraulic binder.

    Voglar, Grega E; Lestan, Domen


    In a laboratory study, Portland cement (15%, w/w) was used for solidification/stabilisation (S/S) of Cd, Pb, Zn, Cu, Ni and As contaminated soils from the former industrial site. Soils formed solid monoliths with cement. S/S effectiveness was assessed by measuring the mechanical strength of the monoliths, concentrations of metals in deionised water and TCLP (toxicity characteristic leaching procedure) soil extracts, and mass transfer of metals. Concentrations of Cd, Pb, Zn and Ni in water extracts from S/S soils generally decreased, concentrations of As remained unchanged, while concentrations of Cu increased. Concentrations of Cd, Pb, Zn and Ni in the TCLP extracts from S/S soils were lower than from original soils. Cu extractability was lower in most soil samples, while the extractability of As from S/S soils increased. Overall, the concentration of metals in deionised water and TCLP solution, obtained after extraction of the S/S soils, was below the regulatory limits. S/S greatly reduced the mass transfer of Cd (up to 83-times), Pb (up to 13.7-times) and Zn (up to 294-times). Mass transfer of Ni and As was generally also reduced, while that of Cu increased in some S/S soils. Based on the findings of mass-transfer mechanism analysis the predominant mechanism of release was surface wash-off of metals otherwise physically encapsulated within the cementous soil matrix.

  4. Patterns of relative magnitudes of soil energy channels and their relationships with environmental factors in different ecosystems in Romania.

    Ciobanu, Marcel; Popovici, Iuliana; Zhao, Jie; Stoica, Ilie-Adrian


    The percentage compositions of soil herbivorous, bacterivorous and fungivorous nematodes in forests, grasslands and scrubs in Romania was analysed. Percentages of nematode abundance, biomass and metabolic footprint methods were used to evaluate the patterns and relative size of herbivory, bacterial- and fungal-mediated channels in organic and mineral soil horizons. Patterns and magnitudes of herbivore, bacterivore and fungivore energy pathways differed for a given ecosystem type and soil depth according to the method used. The relevance of herbivore energy channel increased with soil depth due to higher contribution of root-feeders. Ectoparasites, sedentary parasites and epidermal cell and root hair feeders were the most important contributors to the total biomass and metabolic footprints of herbivores. Metabolic footprint method revealed the general dominance of bacterial-based energy channel in all five types of ecosystems. The influence of altitude and climatic factors on percentages of abundance, biomass and metabolic footprints of herbivores, bacterivores and fungivores decreased with soil depth, whereas the influence of humus content, cation-exchange capacity and base saturation increased. Vegetation, altitude, climate and soil physico-chemical characteristics are important factors that influenced the abundance, biomass and metabolic footprints of herbivores, bacterivores and fungivores.

  6. Investigation of Stabilised Batu Pahat Soft Soil Pertaining on its CBR and Permeability Properties for Road Construction

    Mohd Idrus, M. M.; Singh, J. S. M.; Musbah, A. L. A.; Wijeyesekera, D. C.


    Soil stabilization by adding materials such as cement, lime and bitumen is one of the effective methods for improving the geotechnical properties of soils [11] Nano-particle is one of the newest additives and many studies about using nano-particle in soil improvement has been done but it was given less attention when soft clay soils stabilization is concerned. To evaluate the strength characteristics of stabilized Batu Pahat soft clay, laboratory investigation on early strength gained by the stabilized soil must be conducted to formulate a suitable and economical mix design [10]. To achieve such purpose, the study examined the effect of NanoClay on the California Bearing Ratio and the Permeability of soft clay. The results gained shows that the Nano-Clay is able to increase the strength of the soft clay [9]. The California Bearing Ratio of the soil is increase significantly where the results for the highest percentage of admixture is 14.4% while the permeability of the soil decreases significantly with increasing Nano-Clay whereby the results of the highest percentage of admixture is 2.0187x10-11 m/s. After doing this research, it is proven that Nano-clay can contribute towards better soil stabilization and enhance the quality of soil as subgrade and foundation at large.

  7. Mycorrhizal aspects in slope stabilisation

    Graf, Frank


    In order to re-colonise and stabilise slopes affected by superficial soil failure with plants essential requirements have to be met: the plants must grow the plants must survive sustainably plant succession must start and continuously develop These requirements, however, are anything but easy given, particularly under the often hostile environmental conditions dominating on bare and steep slopes. Mycorrhizal fungi, the symbiotic partners of almost all plants used in eco-engineering, are said to improve the plants' ability to overcome periods governed by strongly (growth) limiting factors. Subsequently, results of investigations are presented of mycorrhizal effects on different plant and soil functions related to eco-engineering in general and soil and slope stabilisation in particular. Generally, inoculation yielded higher biomass of the host plants above as well as below ground. Furthermore, the survival rate was higher for mycorrhized compared to non-mycorrhized plants, particularly under extreme environmental conditions. However, the scale of the mycorrhizal impact may be species specific of both the plant host as well as the fungal partner(s) and often becomes evident only after a certain time lag. Depending on the plant-fungus combination the root length per soil volume was found to be between 0 and 2.5 times higher for inoculated compared to non-inoculated specimens. On an alpine graded ski slope the survival of inoculated compared to non-treated Salix herbacea cuttings was significant after one vegetation period only for one of the three added mycorrhizal fungus species. However, after three years all of the inoculated plantlets performed significantly better than the non-inoculated controls. The analysis of the potential for producing and stabilising soil aggregates of five different ectomycorrhizal fungi showed high variation and, for the species Inocybe lacera, no significant difference compared to untreated soil. Furthermore, inoculation of Salix

    Full Text Available Zlatna area is a high polluted zone with heavy metals due to industrial activity (extraction and processing of non-ferrous area. In spite of the fact that industrial activity was stoped for 2-3 years, the effect of pollution are still obvious. The aim of this paper is to make evident some aspects concerning the impact of pollution on the mineralogical composition of the clay fraction (below 2μ from some soils belonging to dystric cambisol and luvisol type. From the chemical point of view, the effect of pollution is the acidifiation and depletion of bases, reflected by the decrease of values of indices which express soil reaction (pH and soil exchange properties, especially in the surface horizon. From mineralogical point of view, the acidifiation determines a strong alteration of primary minerals (micas and feldspars and just of secondary minerals (illite, evolution beeing towards hydroxy interlayered minerals (intergrade and kaolinite. As result of this alteration the content of kaolinite increases, achiving a double content in the surface horizon of some polluted soils. Sometimes kaolinite becomes the dominant mineral in the clay fraction of some strong polluted soil.

    Instrumental neutron activation analysis (INAA) was used to determine concentrations of 42 elements in samples of surface soil collected at seven sites polluted from various anthropogenic activities and a control site in a relatively clean area. Elements studied were Ag, Al, As, Au, Ba, Br, Ca, Cd, Ce, Co, Cr, Cs, Eu, Fe, Gd, Hf, Hg, K, La, Lu, Mg, Mn, Mo, Na, Nd, Ni, Rb, Sb, Sc, Se, Sm, Sr, Ta, Tb, Th, Ti, U, V, W, Yb, Zn, and Zr. The results are compared with data for trace elements atmospheric deposition in lichen transplants from the same sites. The most severe soil contamination was observed at Copsa Mica from non-ferrous metallurgy. Appreciable soil contamination was also indicated at Baia Mare (non-ferrous mining and metallurgy), Deva (coal-fired power plant, cement and building materials industry), Galati (ferrous metallurgy), Magurele and Afumati (general urban pollution), and Oradea (chemical and light industries). In most cases excessive levels of toxic metals in soils matched correspondingly high values in lichen transplants. Compared to Romanian norms, legal upper limits were exceeded for Zn and Cd at Copsa Mica. Also, As and Sb occurred in excessive levels at given sites. (orig.)

  10. Study on the diagenetic calcareous accumulations in a soil profile from Floresti (Cluj County, Romania

    Horea Bedelean


    Full Text Available The studied calcretes developed in two different levels (horizons in the soil profile from Floreşti (Cluj County. The deposits outcropping in the area are represented by Bartonian-Priabonian sedimentary rocks (Ciuleni Member, Viştea Limestone and the Quaternary horizon (terrace of Someşul Mic River, consisting of pebbles of different origin, which represent the parent rock of the soil. A detailed petrographical and mineralogical description of the calcretes is given below, based on macroscopic, microscopic and X-ray diffraction analysis. It led to the conclusion that the calcretes from the studied profile have a pedogenic origin. The calcretes consist of distinctive subhorizons within the host horizon of the soil. According to their microstructure, the studied calcretes belong to the alpha-type and may be considered as “nodular calcretes” or “glaebular calcretes”. The source of carbonate was variable: from the parent material of the soil including fragments of carbonate rocks, bioclasts, vegetal rests, eolian dust.

  11. Spatial analysis of water infiltration in urban soils. Case study of Iasi municipality (Romania)

    Cristian Vasilica, Secu; Ionut, Minea


    The post-communist period (after 1989) caused important changes in the functional structure of Iasi municipality. The partly dismantling of the industrial area, the urban sprawl against the periurban and agricultural space, the new infrastructure works, all these determined important changes of soils' physical and morphological properties (e.g. porosity, density, compaction, infiltration rate etc., in the first case, and changes in soil horizons, in the second case etc.). This study aims to prove the variability of physical properties through the combination of statistical and geostatistical methods intended for a correct spatial representation. Water infiltration in urban soils was analyzed in relation to land use and the age of parental materials. Field investigations consisted in measurements of the water infiltration (by the means of Turf Tech infiltrometer), resistance to penetration (penetrologger), moisture deficit (Theta Probe) and resistivity (EC) for 70 equally distanced points (750 m x 750 m) placed in a grid covering more than 33 km2. In the laboratory, there were determined several parameters as density, porosity (air pycnometer), gravimetric moisture and other hydrophysical indicators. Filed investigations results are very heterogeneous, because of the human intervention on soils. The curves of variation for the rate water infiltration in soils indicate a downward trend, from high values in first time interval (one minute), between 5000 and 60 mm/h-1, gradually decreasing to the interval of 5-10 minutes (between 30 and 1000 mm/ h-1 to a general trend of flattening after a large time interval (in the timeframe of 50-60 minutes, the infiltration rate ranges between 4 and 142 mm•h-1). The highest frequency (≥65%) caracterizes the infiltration rates between 20 and 65 mm•h-1. For each analyzed sector (residential areas, industrial areas, degraded lands, recreational areas - parks and botanical gardens, forests heterogeneous agricultural lands), the

    Jitareanu, G.; Ailincai, C.; Bucur, D.; Raus, L.; Filipov, F.; Cara, M.


    The mass of total carbon from Cambic Chernozem in the Moldavian Plain has recorded significant increases at higher than N{sub 1}40 P{sub 1}00 rates, in organo-mineral fertilization and in 4-year crop rotation, which included melioration plants of perennial grasses and legumes. In maize continuous cropping and wheat-maize rotation, very significant values of the carbon content were found only in the organo-mineral fertilization, in 4-year crop rotations + reserve field cultivated with perennial legumes and under N{sub 1}40 P{sub 1}00 fertilization. In comparison with 4-year crop rotations, in wheat-maize rotation with melioration plants (annual and perennial legumes and perennial grasses), the mean carbon content from soil has diminished from 18.6 to 16.4 C, g.Kg{sup -}1 and the content in mobile phosphorus decreased from 51.6 to 36.8 P-Al,{sup -}1. The 40 year use of 3 and 4-year crop rotations has determined the increase in total carbon mass and mobile phosphorus from soil by 10% (1.7 C g-kg{sup -}1) and 31%, respectively (11.8 P-Al{sup -}1), against maize continuous cropping.

  15. Relative Prices and Inflation Stabilisation

    Aoki, Kosuke


    When price adjustment is sluggish, inflation is costly in terms of welfare because it distorts various kinds of relative prices. Stabilising aggregate price inflation does not necessarily minimise these costs, but stabilising a well-designed core inflation minimises the cost of relative price fluctuations and thus the cost of inflation.

  16. Use of the 3-D scanner in mapping and monitoring the dynamic degradation of soils. Case study of the Cucuteni-Baiceni Gully on the Moldavian Plateau (Romania.

    G. Romanescu


    Full Text Available The 3-D Scanner, a rapid and precise means of monitoring the dynamics of erosive processes, was used, first of all nationally (Romania, as a new technique of cartography and monitoring the dynamics of soil degradation processes in the Moldavian Plateau. Three sets of measurements took place: in 2008, in 2009 and in 2010, at intervals of exactly one year for the first and six months for the second part. Qualitative and quantitative differences were highlighted. The data obtained were corroborated with precipitation in the area studied. The 3-D scanner has a measurement accuracy of 6 mm. The map highlights the dynamics of gullies developed and may form the basis for the prediction of soil degradation phenomena. The dynamics of the gully and the type of land use show that the phenomenon of erosion of the Moldova Plateau will continue to accelerate. In this case the gully attacked and destroyed an archaeological site of national importance. The rate of advance of the Cucuteni-Baiceni gully is extremely high (10 m/1.6 yr. There are no measures at all to reduce or fight the process of the gully advance. Maximum erosion occurred at the beginning of spring after a winter rich in rainfall, which made the terrain subject to the process of subsidence.

  19. Evaluating the mobility of polymer-stabilised zero-valent iron nanoparticles and their potential to co-transport contaminants in intact soil cores.

    Chekli, L; Brunetti, G; Marzouk, E R; Maoz-Shen, A; Smith, E; Naidu, R; Shon, H K; Lombi, E; Donner, E


    The use of zero-valent iron nanoparticles (nZVI) has been advocated for the remediation of both soils and groundwater. A key parameter affecting nZVI remediation efficacy is the mobility of the particles as this influences the reaction zone where remediation can occur. However, by engineering nZVI particles with increased stability and mobility we may also inadvertently facilitate nZVI-mediated contaminant transport away from the zone of treatment. Previous nZVI mobility studies have often been limited to model systems as the presence of background Fe makes detection and tracking of nZVI in real systems difficult. We overcame this problem by synthesising Fe-59 radiolabelled nZVI. This enabled us to detect and quantify the leaching of nZVI-derived Fe-59 in intact soil cores, including a soil contaminated by Chromated-Copper-Arsenate. Mobility of a commercially available nZVI was also tested. The results showed limited mobility of both nanomaterials; mobility of nZVI below the injection/remediation zone was very limited. This Fe-59 experimental approach can be further extended to test nZVI transport in a wider range of contaminated soil types and textures and using different application methods and rates. The resulting database could then be used to develop and validate modelling of nZVI-facilitated contaminant transport on an individual soil basis suitable for site specific risk assessment prior to nZVI remediation.

    Full Text Available An understanding of soils and how they develop is crucial for explaining why the archeological deposits are located in particular places. This is because the interaction of many soil-forming factors, including climate, topography, vegetation, and parental materials werealso important consideration to humans in deciding where habitation and other site types were established. Soil chemistry is being utilized for paleo-environmental reconstruction. Elements commonly enriched in soil due to human activity include carbon, nitrogen, phosphorous and calcium, potassium and to a lesser degree sulfur, copper and zinc. The geomorphologic survey revealed significant changes of the alluvial landscape around the Late Neolithic/Early Copper Age, tell site of Uivar. Neolithic tell evolution started assoon as fluvial aggradation ceased ~ 6.5 Ka ago at the beginning of the Holocene Climatic Optimum. Basal parts of the colluvium of the tell site date at earliest 4-3.5 ka. The youngest colluvium in foot-slope position may date to the medieval period ~ 1 ka ago.The study showed that the mound is from bottom to the top made up by antrophogenic sediments. The tell site buries a fossil calcaric Fluvisols and at surface an Urbic –Humic – Anthropic –Regosol with an excessive content of mobile phosphorus (650 ppm and mobilepotasium (840 ppm.

  2. Stabilisation of nanoscale zero-valent iron with biochar for enhanced transport and in-situ remediation of hexavalent chromium in soil.

    Su, Huijie; Fang, Zhanqiang; Tsang, Pokeung Eric; Fang, Jianzhang; Zhao, Dongye


    In this study, a biochar-supported nanoscale zero-valent iron (nZVI@BC) material was used for in situ remediation of hexavalent chromium-contaminated soil. Sedimentation tests and column experiments were used to compare the stability and mobility of nZVI@BC and bare-nZVI. The immobilisation efficiency of chromium, toxic effect of chromium and the content of iron were assessed through leaching tests and pot experiments. Sedimentation tests and transport experiments indicated that nZVI@BC with nZVI to BC mass ratio of 1:1 exhibited better stability and mobility than that of bare-nZVI. The immobilisation efficiency of Cr(VI) and Crtotal was 100% and 92.9%, respectively, when the soil was treated with 8 g/kg of nZVI@BC for 15 days. Moreover, such remediation effectively reduced the leachability of Fe caused by bare-nZVI. In addition, pot experiments showed that such remediation reduced the phytotoxicity of Cr and the leachable Fe and was favourable for plant growth.

    Long-term use of artificial fertiliser has a significant impact on soil organic carbon (SOC). We used physical-chemical fractionation methods to assess the impact of long-term (26years) fertilisation in a maize cropping system developed on Brown Earth in Northeast China. Plot treatments consisted of control (CK); nitrogen (N) fertiliser (N2); low-level organic manure combined with inorganic N and phosphorus (P) fertiliser (M1N1P1); medium-level organic manure combined with inorganic N fertiliser (M2N2); and high-level organic manure combined with inorganic N and P fertiliser (M4N2P1). Our objectives were to (1) determine the contents of and variations in the SOC fractions; (2) explore the relationship between total SOC and its fractions. In treatments involving organic manure (M1N1P1, M2N2, and M4N2P1), total SOC and physically protected microaggregate (μagg) and μagg occluded particulate organic carbon (iPOC) contents increased by 9.9-58.9%, 1.3-34.7%, 29.5-127.9% relative to control, respectively. But there no significant differences (P>0.05) were detected for the chemically, physically-chemically, and physically-biochemically protected fractions among the M1N1P1, M2N2, and M4N2P1 treatments. Regression analysis revealed that there was a linear positive correlation between SOC and the unprotected coarse particulate organic carbon (cPOC), physically protected μagg, and iPOC fractions (Pfractions responded negatively to SOC content. The highest rate of C accumulation among the SOC fractions occurred in the cPOC fraction, which accounted for as much as 32% of C accumulation as total SOC increased, suggesting that cPOC may be the most sensitive fraction to fertiliser application. We found that treatments had no effect on C levels in H-μsilt and NH-μsilt, indicating that the microaggregated silt C-fractions may have reached a steady state in terms of C saturation in the Brown Earth of Northeast China.

    Full Text Available The term ecological agriculture has been attributed by the European Union of Romania to define this system of agriculture and is similar with terms organic agriculture or biological agriculture, which are used in other member states. One of the main goals of ecological agriculture is the production of agricultural and food products fresh and genuine through processes created to respect nature and its systems. Thus, it prohibits the use of genetically modified organisms, fertilizers and synthetic pesticides, stimulators and growth regulators, hormones, antibiotics for livestock and the use of synthetic chemical fertilizers, drastic interventions on the soil, the introduction of genetically modified organisms, in the case of the cultivated soil. The study aims to highlight the main features of ecological agriculture and its impact on the national economy. Through a descriptive and comparative analysis of specific indicators are surprising the main aspects of ecological agriculture performance in Romania and are identified investment opportunities in this sector of the national economy. Following this study, it was found that ecological agriculture in Romania is quite performant and recorded a continuous development, but mainly in the production, not in the processing and trading of natural products, which is why investment in these areas would be welcome.

  9. Reset stabilisation of positive linear systems

    Zhao, Xudong; Yin, Yunfei; Shen, Jun


    In this paper, the problems of reset stabilisation for positive linear systems (PLSs) are investigated. Some properties relating to reset control of PLSs are first revealed. It is shown that these properties are different from the corresponding ones of general linear systems. Second, a class of periodic reset scheme is designed to exponentially stabilise an unstable PLS with a prescribed decay rate. Then, for a given PLS with reset control, some discussions on the upper bound of its decay rate are presented. Meanwhile, the reset stabilisation for PLSs in a special case is probed as well. Finally, two numerical examples are used to demonstrate the correctness and effectiveness of the obtained theoretical results.

    Full Text Available The increasing world population, the limitation of the natural availability for food production, the climate issues and the food consumption need for modification imposed a continuous updating of the food security concept. Although Romania has sufficient natural resources, which may ensure, by means of proper exploitation, the population’s food needs, the lack of a unitary approach at the government level, materialized in the dependence on imports and in fluctuations in the agro-food production, leads to a re-evaluation of national food needs. National food security may be affected by a series of risks and threats, which appeared due to an imbalance connected with the availability, the utility and the stability of the agro-food sector, interdependent elements that must be functional. The present article proposes an analysis of food security in Romania, with a short presentation of the concept in an international context.

  17. Phytoremediation Possibilities for Contaminated Mining Areas from Romania

    COMAN Mirela


    Full Text Available Mining activities, which have been carried out in Romania for centuries, resulted in pollution of large areas,affecting negatively the environment and representing a threat for human health. This paper aims to prove that inRomania can host a relatively new, costly efficient and sustainable remediation technique for contaminated miningsites, namely phytoremediation. The applicability of phytoremediation for remediation of contaminated areas wasproven by several demonstration projects carried out worldwide. It has a very positive impact on the landscapeaesthetics, resulting in a high public acceptability. Moreover, the climate and soil conditions in Romania allow the useof several plant species which can remove contaminants from water and soil. It is therefore concluded that thesuccessful implementation of phytoremediation on contaminated mining sites in Romania can be achieved, but undercertain conditions. These conditions include the promotion of this technology by finding appropriate ways to transferknow-how and to build capacity at the level of public institutions and organizations dealing with remediation of themining areas.

  19. Romania: Health System Review.

    Vladescu, Cristian; Scintee, Silvia Gabriela; Olsavszky, Victor; Hernandez-Quevedo, Cristina; Sagan, Anna


    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

    Full Text Available The aim of this research is to study the patterns of migration in Romania. Labor migration in Romania has seen major growth after 1989. Permanent migration rapidly increased in the early years after the revolution, decreasing rapidly thereafter, due to difficulties of obtaining long term residence and work permit in the host countries. However, temporary migration has been found to evolve very dynamically, requiring economic analysis of potential externalities, whether positive or the negative of this phenomenon.

  4. Desecularisation in Postcommunist Romania

    KISS, Dénes


    Full Text Available The paper gives an analysis of the process as a result of which postcommunist Romania has moved from being an officially atheist country to being one of the most religious countries in Europe. Th e process of desecularisation is analysed in three dimensions. On the macro-level, I outline the religious headway in the most important institutions of the Romanian society, on the meso-level I analyse the changes in the organizational structure of churches and in the denominational structure of the country, while on the individual level the changes occurring in individual religiosity. In the fi nal part of the study I argue that within these dimensions desecularisation was realized to diff erent extents, while “desecularisation from above” is not likely to achieve its goals in the long run.

This is carried out by evaluating the importance level given to the principles of corporate governance in the Romanian economy, while the practices of transparency and dissemination of companies’ information in the selected sample were monitored. To achieve the objectives of the study, we need to examine the Corporate Governance Code of the Bucharest Stock Exchange. Sample companies were selected and their information from the “Comply or Explain” Statements was analyzed.The research method is a non-participating observation—based on the information from the “Comply or Explain” Statement to determine whether companies are applying corporate governance and transparency elements. The research results highlight the progress of Romanian companies in the process of exercising to the principles of corporate governance, becoming internationally recognized, and integrating into the Corporate Governance Code of the Bucharest Stock Exchange.

  6. Corruption in Romania

    Silviu DUȚULESCU


    Full Text Available Corruption as a phenomenon is of great interest for the society we live in. As there is no unit of measurement to determine the scale of this phenomenon, comparative studies are chosen most often for the areas concerned. The present paper describes a study focused on all counties in Romania, Bucharest included. The purpose of this research is to establish the determinant factors that influence the size and spread of corruption, as it manifests strong negative effects on the society we live in. Thus, using a set of regressions over the main variables, some correlation coefficients have been set, which after processing rendered a ranking of all the 42 analysed territorial units, sorted by the estimated size of corruption. The whole scientific approach was completed with a map of corruption, which synthesizes and presents the corruption spread nationwide




    Full Text Available I chose this topic because my goal was to capture in detail all aspects of the evolution of investment funds under the influence of factors leading to globalization of the banking financial market. Main motivation was that I proposed to present in an original manner the concept of investment in mutual funds by the thoroughness of the following points: the different types of investment funds from Romania, the advantages, the risks and the specific costs of the investment in mutual funds and the effects of the financial crisis on the industry of the investment funds on the national level. The financial crisis and the risk of infecting the global economy affected the taste of risk of the investors and their request for the investment fund, determining the orientation of the investors to the funds with a lower risk – the diversified funds, the funds of bonds and the monetary funds. I considered important the theoretical approach of the concept of investments in investment funds because they are a barometer of the macro economical stability, in case the economical increase is positive on the macro economical level the investments in investments funds are increasing too. In Romania the market of the mutual funds is at an incipient level, but with potential and perspectives of development. Due to the bankruptcy of FNI in the beginning of the years 2000 and due to the absence of a clear legislation regarding the calculation of the unitary value of the net asset and the control of the activity developed by the investment funds, the development of the industry of the investment funds had to fight against the crisis of credibility generated by these events. The convergence of the Romanian economy to the European standards will attract also a modification of the structure of the financial investments of the individuals, by an increase of the investments in funds. In the world the investment funds are preferred by the investors for their advantages

  8. Social Contributions in Romania

    Attila Gyorgy


    Full Text Available Social contributions have an important impact on payroll policy. Also, social contributions represent a significant budgetary revenue item which can be viewed at the edge between taxation and insurance. Social contributions in Romania experienced many changes which ended in 2008. Nowadays, they are within a long transaction period towards partial externalization of the insurance activity to privately managed funds. The aim of this paper is to analyse the homogeneity of Romanian social security public scheme using annual data extracted from 2002-2009.The main findings reveal that social contributions reached the pinnacle of diversification, being too many, some of them with a small contribution rates; fiscal reforms which reduced contribution rates advantaged employers, and state will be interested to externalize this activity as far private sector will be able to assume this responsibility and the budgetary effects are acceptable for the public finance.

  9. A priori calculations for the rotational stabilisation

    Iwata Yoritaka


    Full Text Available The synthesis of chemical elements are mostly realised by low-energy heavy-ion reactions. Synthesis of exotic and heavy nuclei as well as that of superheavy nuclei is essential not only to find out the origin and the limit of the chemical elements but also to clarify the historical/chemical evolution of our universe. Despite the life time of exotic nuclei is not so long, those indispensable roles in chemical evolution has been pointed out. Here we are interested in examining the rotational stabilisation. In this paper a priori calculation (before microscopic density functional calculations is carried out for the rotational stabilisation effect in which the balance between the nuclear force, the Coulomb force and the centrifugal force is taken into account.

  10. Impact of a high severity wildfire and two post-fire stabilisation treatments on the structure of the microbial community in a soil located in Laza (Ourense, NW Spain

    A. Lombao


    Full Text Available Studies concerning the microbial communities in burnt soils have been focused on biochemical properties and, despite its interest, information about the microbial community structure is scarce. The aim of this study was to evaluate the short- and medium- term effects produced by a high severity fire and the application of post-fire stabilization methods (mulching and seeding in the structure of soil microbial population, determined by means of the analysis of phospholipid fatty acids (PLFA. The study was performed in a forest ecosystem affected by a high severity wildfire and highly susceptible to post-fire soil erosion (Laza, NW Spain. Samples were collected from the A horizon (0-2 cm immediately and 4, 8 and 12 months after the wildfire. The results of principal component analysis carried out with PLFA data make possible to differentiate between burnt and unburnt samples, indicating a clear effect of the wildfire on composition of microbial communities. Unburnt samples were characterized by the presence of fungal fatty acid as 18:2ω6, 18:1ω9 o 16:ω5, whereas fatty acid characteristics of actinomycetes tended to be higher in burnt samples than in the corresponding unburnt samples. The structure of microbial communities also varied with sampling time, confirming seasonal fluctuations of soil microbial parameters.

  11. Stabilising the Planck mass shortly after inflation

    van de Bruck, Carsten; Robinson, Mathew


    We consider a model of the early universe which consists of two scalar fields: the inflaton, and a second field which drives the stabilisation of the Planck mass (or gravitational constant). We show that the non-minimal coupling of this second field to the Ricci scalar sources a non-adiabatic pressure perturbation. By performing a fully numerical calculation we find, in turn, that this boosts the amplitude of the primordial power spectrum after inflation.

    Attanasio, Felipe


    Complex Langevin methods have been successfully applied in theories that suffer from a sign problem such as QCD with a chemical potential. We present and illustrate a novel method (dynamic stabilisation) that ensures that Complex Langevin simulations stay close to the SU(3) manifold, which lead to correct and improved results in the framework of pure Yang-Mills simulations and QCD in the limit of heavy quarks.




    Full Text Available Last few years have shown that Romania is not protected from the consequences of climate change. It is clear that type flood events may cause social problems and losses is difficult financing from public resources, especially in the context of the existence of budget constraints. The only viable system to cope with such disasters is insurance system that has the ability to spread risks by reinsurance Natural disasters - earthquakes, floods, landslides - are just some of the risks that may threaten your home. And if natural disasters can seem distant danger, think as fires, floods caused by broken pipes or theft of household goods are trouble can happen anytime to anyone. To protect yourself in such unpleasant situations, whose frequency is unfortunately on the rise, it is necessary to be assured. Thus, you will be able to recover losses in the event that they occur. The house is undoubtedly one of the most important assets we own. Therefore, the Romans began to pay increasingly more attention to domestic insurance products. Since 2011, voluntary home insurance, life insurance with, were the most dynamic segments of the market.

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

    Cosma, C; Cucoş Dinu, A; Dicu, T


    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.

  16. Embodied energy in cement stabilised rammed earth walls

    Venkatarama Reddy, B.V.; Prasanna Kumar, P. [Department of Civil Engineering, Indian Institute of Science, Bangalore 560012 (India)


    Rammed earth walls are low carbon emission and energy efficient alternatives to load bearing walls. Large numbers of rammed earth buildings have been constructed in the recent past across the globe. This paper is focused on embodied energy in cement stabilised rammed earth (CSRE) walls. Influence of soil grading, density and cement content on compaction energy input has been monitored. A comparison between energy content of cement and energy in transportation of materials, with that of the actual energy input during rammed earth compaction in the actual field conditions and the laboratory has been made. Major conclusions of the investigations are (a) compaction energy increases with increase in clay fraction of the soil mix and it is sensitive to density of the CSRE wall, (b) compaction energy varies between 0.033 MJ/m{sup 3} and 0.36 MJ/m{sup 3} for the range of densities and cement contents attempted, (c) energy expenditure in the compaction process is negligible when compared to energy content of the cement and (d) total embodied energy in CSRE walls increases linearly with the increase in cement content and is in the range of 0.4-0.5 GJ/m{sup 3} for cement content in the rage of 6-8%.

    Moeglin, Colette


    Ce travail en deux volumes donne la preuve de la stabilisation de la formule des trace tordue. Stabiliser la formule des traces tordue est la méthode la plus puissante connue actuellement pour comprendre l'action naturelle du groupe des points adéliques d'un groupe réductif, tordue par un automorphisme, sur les formes automorphes de carré intégrable de ce groupe. Cette compréhension se fait en réduisant le problème, suivant les idées de Langlands, à des groupes plus petits munis d'un certain nombre de données auxiliaires; c'est ce que l'on appelle les données endoscopiques. L'analogue non tordu a été résolu par J. Arthur et dans ce livre on suit la stratégie de celui-ci. Publier ce travail sous forme de livre permet de le rendre le plus complet possible.

  18. SAPHYR: A new chemical stabilisation process

    Baratto, Gilles; Fernandes, Paulo; Patria; Lucie; Cretenot, Didier


    Odour control and dewaterability are the key criteria during biosolids storage either for use on land or incineration. In the case of use on land, stabilisation/sanitisation are also part of the key criteria. Vivendi Water Systems developed the SAPHYR process to answer those three requirements. The SAPHYR process principle is based on an acidification of biosolids associated to the addition of nitrite. The main results are a noticeable odour control lasting other periods of 6 to 9 months, an improved dewaterability (2 to 4 points of dryness) and depending on chemical dosages a stabilisation or a sanitisation of biosolids. Another characteristic is that biosolids conditioned with the Saphyr process can be used both on land or for incineration. After several demonstrations on more than 5 different plants throughout France on a 10 000 p.e. unit, the first industrial reference of the process was installed on a 50 000 population equivalent wastewater treatment plant in 2002 and has been in operation since december 2002. A close monitoring of the process operation, the biosolids quality and its storage and spreading on land is planned from November 2002 to spring 2003. A comparison with lime addition will take place on the same plant. The present paper will produce a presentation of the SAPHYR process, its operation on a 50 000 pe WWTP and its different applications for biosolids storage.

  19. How Crowdfunding Works in Romania?

    Mădălina Bălău


    Full Text Available Crowdfunding is increasingly becoming a good solution for entrepreneurial ventures to obtain funds, being facilitated by internet and social networks, and it is also spreading in Romania as well. The current paper aims to explore this alternative for financing in Romania in order to understand better its evolution until now, whether if it is viewed as suitable for business as well, and to compare the advices offered for entrepreneurs in Romania versus those on famous crowdfunding sites such as Kickstarter and Indiegogo. In order to achieve this we explored websites offering crowdfunding in Romania and the information they offer entrepreneurs, we identified the types of most successful campaigns and we compared advices offered to those existing on international websites, renowned for their success. The marketing strategy and the planning of the campaign seem to be essential for its success and this paper highlights in its conclusion some lessons Romanian entrepreneurs could learn from international crowdfunding campaigns and the growing scientific literature available on this subject.

    Full Text Available If during the interwar period Romania has managed to move from an agrarian economy to an industrial-agrarian one, after the 2nd world war in Romania, as in other communist countries, has monitored the further development of the industry. It wanted to be a true industrial revolution.Over time one can identify several types of industrial revolutions, each giving impetus to a given development cycle, which had its beneficiaries and the losers. At first it was steam power, and then use the internal combustion engine, which used oil instead of steam. While other countries developed would increase of production capacity of nuclear power, a higher stage of economic development, in Romania continued the industrial development on the same grounds as in the inter-war period. This has had very serious tracks for the Romanian economy and society, since before and during World War II, the German war machine operated within the national resources of energy. The time and manner in which each country is part of this race are defining the social welfare. Unfortunately, Romania has failed to take advantage, each time losing the start. Creation of some production capacity and the development of industries (metallurgy, chemical industry, iron and steel industry, which consumed significant energy amounts was the wrong decision for the future well-being of the country. Oil impacts which have affected the world economy, hit also Romania. The first oil shock (impact was more easily broken because of the continued use of internal resources (oil, coal, natural gas, but the second shock was catastrophic. It was too much for Romania after being forced to use those resources in the last decades (including the interwar period. Romanian leaders probably had in mind that Western countries were developed by enhancing industry of this type, but they did it in a different historical period when also the prices of such resources were much smaller and the lack of them was not a

  1. The stabilisation of final focus system

    P A Coe; D Urner; A Reichold


    The StaFF (stabilisation of final focus) system will use interferometers to monitor the relative positions and orientations of several key components in the beam-delivery and interaction region. Monitoring the relative positions of the ILC final focus quadrupole magnets will be the most demanding application, where mutual and beam-relative stability will have a direct impact on machine luminosity. Established, laser-based frequency scanning interferometry (FSI) and fixed-frequency interferometry (FFI) offer positional resolution at length scales of the laser wavelength (1500 nm to 1560 nm) and a thousandth of the wavelength, respectively. As part of the ATF at KEK, StaFF will use interferometers to measure lines of a geodetic network to record relative motion between two beam position monitors. Interferometers are being designed and tested in Oxford prior to deployment at the ATF.

  2. Aqueous foams stabilised solely by nanoparticles

    Langevin, Dominique


    Particles are being increasingly used to stabilise foams and emulsions, the corresponding emulsions being known as ``Pickering'' emulsions. One of the peculiarities of these systems is the absence of Ostwald ripening: since the bubbles or drops do not grow (coalescence seems also suppressed) both foams and emulsions are stable over extremely long periods of time (months). These features make particles very interesting surface active agents as compared to standard surfactants or polymers/proteins. The origin of the suppression of ripening can be traced to the unusual behaviour of the interfacial layers made by these particles. The layers are solid-like and the usual characterisation methods (surface tension, surface rheology) are not straightforward to use. In this presentation, we will illustrate these difficulties with experiments made with partially hydrophobic silica nanoparticles. We will also discuss the relevance of foam characterisations methods such as multiple light scattering and X-ray tomography.

  11. Open Geodata Initiative for Romania

    Craciunescu, Vasile; Iosifescu, Ionut; Ilie, Codrina Maria; Gaitanaru, Dragos; Radu Gogu, Constantin; Hurni, Lorenz


    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.

  14. Thermo stabilisation of poly (butylene adipate-co-terephthalate

    Rodrigo Paulino Chaves

    Full Text Available Abstract Poly (butylene adipate-co-terephthalate - PBAT is a synthetic biodegradable polymer commonly used for plastic film production from neat polymer or nanocomposites. The PBAT is submitted to high temperatures and shear rate during its processing. In the present study, the thermo stabilisation of PBAT by the addition of two types of stabilisers was studied using a torque rheometer at 60 rpm and two levels of temperature. The stabilisers were used as master batches with a percentage of 10% by weight of additive in the PBAT. Molecular weight, torque values after 10 minutes of mixing, and absorbance at 400 nm were used to evaluate the process of stabilisation. The primary and secondary antioxidant used here had a positive effect on both processing temperatures, 180 and 200 °C. The best results indicate that the primary antioxidant could be used alone to protect PBAT against thermodegradation reactions.

    Full Text Available Forests are one of the richest ecosystems in terms of biomass stock and this potential is augmented by a broad range of ecosystem services that contribute to human wellbeing by protecting air from pollution, soil from runoff, landscapes from flooding and landslides. This high economic and ecologic potential is well acknowledged, but in specific circumstances short terms gains resulting from the valuation of wood or from conversion of land to other uses are prevailing and create powerful incentives for overexploitation or deforestation. The anthropogenic pressure on forests was and continues to remain high at global level, although there are states where it was successfully controlled. Nevertheless, the forest cover is shrinking increasing the associated threats that result from the cancellation of the forests’ ecosystem services. Of particular importance in the current context is the reduction of forests’ carbon sequestration potential, which is of crucial importance in climate change mitigation. The patterns of unfavourable circumstances are analysed in order to outline the most important challenges of forest management in Romania, but also the impact of novel ecosystem service based economic tools that are aimed to strengthen the incentives for sustainable forest management and to avoid conversion of forests to other land use types.

    Dumitru Laurentiu ANDREI


    Full Text Available The transition from a payment system on paper support to an electronic one in Romania was determined, on the one hand, by the development of the financial markets and the significant increase of the activity performed by means of payment systems, and on the other hand, by the need to move to a predominantly cashless society and to streamline cashless payments, as well as by the requests of the final customers for payment services that are safe, effective and low cost.

  20. A framework for the ecological rehabilitation of degraded soilscapes in Eastern Romania

    Bireescu, Geanina; Lo Papa, Giuseppe; Dazzi, Carmelo


    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.

  1. Influence of Geosta Addition on Cement-stabilised Chicoco Mud of the Niger Delta

    Olujide Omotosho


    Full Text Available Chicoco is a very soft and extremely compressible organic marine mud found extensively and to considerable depths within the saline tidal flat or mangrove swamp of the Niger delta in southern Nigeria. Natural chicoco is highly undesirable, barely able to support a human of average weight but air-dried chicoco has been used successfully by the indigeneous people for shore protection, etc. especially if placed above water. Plain cement stabilization of most organic soils (including chicoco is known to be ineffective. In this study, geosta, a chemical stabiliser relatively newly developed for organic soils was combined with ordinary Portland cement to stabilise chicoco. It was observed that neutralisation of acidic "air-dried" chicoco by basic geosta inhibited the expected ion-exchange reaction and its attendant improvement on mechanical properties. As a result and as geosta content increases, maximum dry density (MDD was found to be only marginally improved but better for higher cement contents while optimum moisture content (OMC decreases but with higher values for lower cement contents. Unsoaked CBR (but with samples wax-cured for 3 days on the other hand was found to maximise at low geosta content and thereafter decreases continually - a major cost advantage in earthworks. In fact, the most effective influence was obtained at 4.0% cement plus about 1.5% geosta. This stabilization was also found to produce optimum road sub-base materials.

  2. Water from Romania's heart!

    Lup, M.


    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

  3. Exploring Educational Inequalities in Romania

    Ana-Maria ZAMFIR


    Full Text Available In the recent period, social inequalities have become a research topic of great interest for many scientists in the world. The participation of individuals to education is an important determinant for their access to subsequent opportunities, especially labor market opportunities. Moreover, an important number of studies show that education is one of the most influential factors that explain the amount of resources available to individuals in all their life cycles. In this context, reducing school dropout and increasing the share of individuals graduating from higher education represent national objectives for Romania. This article aims to analyze factors that explain differences in participation to education. A special attention will be given to urban-rural gaps in educational attainment. While taking into account main theoretical developments in the field of educational inequalities, empirical data are analyzed in order to provide a clearer picture on the factors that influence the access of individuals to higher education in Romania. Results are useful for policy makers and managers in the education field for better designing policies and study programs that are inclusive and provide better life chances to all individuals.

    We combine moduli stabilisation and (chiral) model building in a fully consistent global set-up in Type IIB/F-theory. We consider compactifications on Calabi-Yau orientifolds which admit an explicit description in terms of toric geometry. We build globally consistent compactifications with tadpole and Freed-Witten anomaly cancellation by choosing appropriate brane set-ups and world-volume fluxes which also give rise to SU(5)- or MSSM-like chiral models. We fix all the Kaehler moduli within the Kaehler cone and the regime of validity of the 4D effective field theory. This is achieved in a way compatible with the local presence of chirality. The hidden sector generating the non-perturbative effects is placed on a del Pezzo divisor that does not have any chiral intersections with any other brane.

  9. Southwick Osteotomy Stabilised with External Fixator

    Grubor, Predrag; Mitkovic, Milorad; Grubor, Milan


    ABSTRACT Introduction: Epiphysiolysis of the femoral head is the most common accident occurring towards the end of pre-puberty and puberty growth. Case report: The author describes the experience in the treatment of chronic epiphysiolysis in two patients treated by Southwick osteotomy. The site is accessed by way of a 15-cm long lateral skin incision and the trochanteric region is reached through the layers. The osteotomy angles prepared beforehand on a thin aluminium model are used to mark the Southwick osteotomy site on the anterior and lateral sides at the level of the lesser trochanter. Before performing the trochanteric osteotomy, two Mitković convergent pins type M20 are applied distally and proximally, above the planned osteotomy site. A tenotomy of the iliopsas muscle is performed, and then the previously marked bone triangle is redissected up to three quarters of the width of the femur. The distal part of the femur is rotated inwards, so that the patella is turned towards the ceiling. The osteotomised fragments of the femur are adapted, repositioned and fixated by installing an external fixator on the previously placed pins. Two more pins are placed, one proximally and one distally, with a view to adequately stabilising the femur. The patient was mobile from day two after the surgery. If, after the surgery, the lead surgeon realises that there is a requirement to make a correction of 5, 10 and 15 degrees of the valgus, varus, anteversion or retroversion deformity, the correction shall be performed without surgically opening the patient, using the fixator pins. Conclusion: After performing a Southwick osteotomy it is easier to adapt, reposition and fixate the osteotomised fragments of the femur using a fixator type M20. Adequate stability allows regaining mobility quickly, which in turn is the best prevention of chondrolysis of the hip. It is possible to make post-operative valgus, varus, anteversion and retroversion corrections of 5, 10 and 15 degrees

  11. War, Peace and Stabilisation: Critically Reconceptualising Stability in Southern Afghanistan

    William Robert Carter


    Full Text Available This article critically treats stabilisation theory and programming through a perspective of peace and conflict, and argues for stabilisation’s reconceptualisation. Through tracking the concept’s emergence, it outlines that stabilisation is theoretically rooted in an insecurity-underdevelopment problematic and relies on the Liberal Peace thesis as a solution. When this concept was operationalised in southern Afghanistan, however, it was translated into a praxis informed by state-building and counterinsurgency imperatives. This approach ultimately produced confused, sometimes counterproductive, effects: simultaneously engendering a liberal, negative, rented and victor’s peace. The article concludes by arguing that stabilisation should be reconceptualised so that it pursues a positive and hybrid peace if it is to be a more effective source of guidance for policy and practice. The first step is to denaturalise the ‘formal’ state in conflict and fragile environments as being seen as a panacea to all ills of instability.

In Romania, regional experiences, in different forms, dating back to the interwar period. Currently, the institutional framework, objectives, powers and instruments of regional development policy in Romania was established by Law no. 315/2004 on regional development in Romania, but not developing regions and municipalities have no legal personality and therefore be a reform aimed at regionalization of Romania. Under the provisions of article 3, 1 of the Constitution, republished, Romanian territory is organized administratively into communes, towns and counties. It is therefore necessary to amend the Constitution in order to create the legal framework for regionalization constitutional Romania and then passing bills related to regionalization and administrative decentralization to properly delineate the respective responsibilities of administrative units in Romania.

    Full Text Available The land fund of Romania represents a huge potential for agriculture. The potential has proved difficult to achieve, and among the main vulnerabilities researched lately, we have identified the decline in consumption of vegetable crops, fruit and meat, determined by the declining purchasing power in Romania and the European Union's common market. Therefore the degree of achievement of the agricultural potential is directly influenced by economic developments in Romania and EU Member States. The technical endowment of Romanian farmers is an old and still unresolved problem. Even though Romania has benefited from EU pre-accession funds and still benefits from it, they proved to be a poor solution for Romanian farmers with farm machinery equipment. Indicator analysis of the evolution of the number of tractors in Romania in the post-accession period, reveals that the actual number of tractors in the period under review increased overall, but even if the total number of tractors in Romania increased from 2007 until 2012, UAA (ha per a tractor is almost constant.

  19. Bounded stabilisation of stochastic port-Hamiltonian systems

    Satoh, Satoshi; Saeki, Masami


    This paper proposes a stochastic bounded stabilisation method for a class of stochastic port-Hamiltonian systems. Both full-actuated and underactuated mechanical systems in the presence of noise are considered in this class. The proposed method gives conditions for the controller gain and design parameters under which the state remains bounded in probability. The bounded region and achieving probability are both assignable, and a stochastic Lyapunov function is explicitly provided based on a Hamiltonian structure. Although many conventional stabilisation methods assume that the noise vanishes at the origin, the proposed method is applicable to systems under persistent disturbances.

    Jeserevics, J; Srenk, P; Beranekl, J; Jaggy, A; Touru, S; Cizinauskas, S


    Ten miniature breed dogs with atlantoaxial subluxation underwent ventral lag screw stabilisation. The procedure did not include bone graft packing into the atlantoaxial articulation. Four dogs showed continuous improvement after surgery. Three dogs developed complications due to external trauma and postoperative implant failure but improved with conservative therapy. Three patients died or were euthanized in early perioperative or postoperative period. The long-term outcome was good or favourable in all surviving patients. Suspected fibrous tissue proliferation and stabilisation without permanent bone fusion was found to be clinically satisfactory when the atlantoaxial joint has been subjected to limited stress during a long-term monitoring period.




    Full Text Available Capital is the main factor of production, business development becomes virtually impossible without taking into account the financial market and the resources it provides to businesses. Any business, regardless of its degree of development, is involving direct contact with financial markets, namely the institutions that mediate mobilization of capital and the services they provide. Understanding the functioning of the financial system, the specific financial mechanisms through which savings are allocated to support capital investments and the costs and risks involved is essential for the development of a solid base for business. In this context, factoring operations can support economic agents, allowing a transfer of commercial receivables from their holder to a factor who commits to their recovery and guarantee such operations even if temporary or permanent insolvency of the debtor . Thus, factoring is a complex technique in at least two aspects, of the debt and the transfer of credit. . Factoring is a means of financing business, especially export-import transactions, less known in Romania. Maybe because of poor business environment popularize the term is as little known as it was a few years ago the leasing. Present in Romanian legislation since 2002, factoring appears as a contract between one party (called adherent, providing goods or service and a banking company or a financial institution specialized (called factor, which the last one shall finance debts pursuing and preservation against credit risks and adherent gives factor by way of sale, debts arising from the sale of goods or services to third parties. The article is divided into three parts. In the first part we defined the concept of factoring and international factoring, then I presented the advantages and development of factoring in Romania, and the last part conclusions.

  6. Modelling and experiments on NTM stabilisation at ASDEX upgrade

    Urso, Laura


    In the next fusion device ITER the so-called neoclassical tearing modes (NTMs) are foreseen as being extremely detrimental to plasma confinement. This type of resistive instability is related to the presence in the plasma of magnetic islands. These are experimentally controlled with local electron cyclotron current drive (ECCD) and the island width decay during NTM stabilisation is modelled using the so-called Modified Rutherford equation. In this thesis, a modelling of the Modified Rutherford equation is carried out and simulations of the island width decay are compared with the experimentally observed ones in order to fit the two free machine-independent parameters present in the equation. A systematic study on a database of NTM stabilisation discharges from ASDEX Upgrade and JT-60U is done within the context of a multi-machine benchmark for extrapolating the ECCD power requirements for ITER. The experimental measurements in both devices are discussed by means of consistency checks and sensitivity analysis and used to evaluate the two fitting parameters present in the Modified Rutherford equation. The influence of the asymmetry of the magnetic island on stabilisation is for the first time included in the model and the effect of ECCD on the marginal island after which the mode naturally decays is quantified. The effect of radial misalignment and over-stabilisation during the experiment are found to be the key quantities affecting the NTM stabilisation. As a main result of this thesis, the extrapolation to ITER of the NTM stabilisation results from ASDEX Upgrade and JT-60U shows that 10MW of ECCD power are enough to stabilise large NTMs as long as the O-point of the island and the ECCD beam are perfectly aligned. In fact, the high ratio between the island size at saturation and the deposition width of the ECCD beam foreseen for ITER is found to imply a maximum allowable radial misalignment of 2-3 cm and little difference in terms of gained performance between

  7. Food-grade Pickering emulsions stabilised with solid lipid particles.

    Pawlik, Aleksandra; Kurukji, Daniel; Norton, Ian; Spyropoulos, Fotis


    Aqueous dispersions of tripalmitin particles (with a minimum size of 130 nm) were produced, via a hot sonication method, with and without the addition of food-grade emulsifiers. Depending on their relative size and chemistry, the emulsifiers altered the properties of the fat particles (e.g. crystal form, dispersion state and surface properties) by two proposed mechanisms. Firstly, emulsifiers modify the rate and/or extent of polymorphic transitions, resulting in the formation of fat crystals with a range of polarities. Secondly, the adsorption of emulsifiers at the particle interface modifies crystal surface properties. Such emulsifier-modified fat particles were then used to stabilise emulsions. As the behaviour of these particles was predisposed by the kind of emulsifier employed for their manufacture, the resulting particles showed different preferences to which of the emulsion phases (oil or water) became the continuous one. The polarity of the fat particles decreased as follows: Whey Protein Isolate > Soy Lecithin > Soy Lecithin + Tween 20 > Tween 20 > Polyglycerol Polyricinoleate > no emulsifier. Consequently, particles stabilised with WPI formed oil-in-water emulsions (O/W); particles stabilised solely with lecithin produced a highly unstable W/O emulsion; and particles stabilised with a mixture of lecithin and Tween 20 gave a stable W/O emulsion with drop size up to 30 μm. Coalescence stable, oil-continuous emulsions (W/O) with drop sizes between 5 and 15 μm were produced when the tripalmitin particles were stabilised with solely with Tween 20, solely with polyglycerol polyricinoleate, or with no emulsifier at all. It is proposed that the stability of the latter three emulsions was additionally enhanced by sintering of fat particles at the oil-water interface, providing a mechanical barrier against coalescence.

  8. Implementation of corporate governance principles in Romania

    Ramona Iulia Țarțavulea (Dieaconescu


    Full Text Available The paper aims to conduct a study regarding the manner in which corporate governance principles are applied in Romania, in both public and private sector. In the first part of the paper, the corporate governance principles are presented as they are defined in Romania, in comparison with the main international sources of interest in the domain (OECD corporate governance principles, UE legal framework. The corporate governance (CG principles refer to issues regarding board composition, transparency of scope, objectives and policies; they define the relations between directors and managers, shareholders and stakeholders. The research methodology is based on both fundamental research and empirical study on the implementation of corporate governance principles in companies from Romania. The main instrument of research is a corporate governance index, calculated based on a framework proposed by the author. The corporate governance principles are transposed in criteria that compose the framework for the CG index. The results of the study consist of scores for each CG principles and calculation of CG index for seven companies selected from the public and private sector in Romania. The results are analyzed and discussed in order to formulate general and particular recommendations. The main conclusion of this study is that that a legal framework in the area of corporate governance regulation is needed in Romania. I consider that the main CG principles should be enforced by developing a mandatory legal framework.

    Full Text Available This paper tries to present the main categories (types of risks that affect the inflows of foreign direct investment (FDI in Romania, such as: country risk, political risk, economic risks, sovereign risks and so on. FDI is an important factor contributing to the economic development and to the economic growth of a country. In order to recuperate its economic handicap as compared to the other countries in the EU, Romania needs a massive inflow of foreign capital, especially in the form of direct investment. The paper also presents the evolution of FDI inflows in Romania and how they were influenced by the main factors affecting the FDI. In principle, between risk and the level of FDI inflows there is a direct dependency relationship: the higher the risk is in a country, the lower the level of FDI inflows is in that country. This is demonstrated by the empirical studies regarding FDI. These studies show that countries with high risk have major difficulties in attracting foreign investment. Therefore, it is important to identify very precisely the main risks that may affect the level of FDI inflows in Romania, in order to propose and implement strategies to mitigate these risks and to attract more foreign direct investment in Romania.

Romania disposes of tradition and favourable pedo-climatic conditions for cultivating the oilseeds plants. This is demonstrated by the favourable results obtained in the last years, especially concerning the sunflower crop. In 2013, Romania registered a record for sunflower, occupying the first position in the European Union for cultivated area and production. A negative aspect is represented by the fact that our country has the best conditions in Europe for soybean crop, but it is still dependent on import. Romania imports a huge quantity of soybean oilcakes for animal feeding. Nowadays, Romania is an important actor in the sunflower world market, covering almost 19% of the global demand. In perspective, one could expect significant oilseeds productions with a positive influence on the agro-food trade balance in our country.

  11. Stabilisation of bank slopes that are prone to liquefaction in ecologically sensitive areas.

    Nestler, P; Stoll, R D


    A consequence of lignite stripping in the Lusatia mining district (East Germany) is the backfilling of dumps that mainly consist of low-compacted fine and medium-grained sands. When the ground-water table, which had been lowered while stripping the coal, is rising again, these dumps might be affected by a settlement flow due to the liquefaction of soils. Common methods for stabilisation as, for instance, blasting or vibrator-jetting deep compaction, are not very useful in ecologically sensitive areas, where dumps have been afforested and embankment areas of residual lakes have developed into highly valuable biotopes. A new so-called air-impulse method in combination with directional horizontal drilling has been developed, which does not have a considerably negative impact on the vegetation during compaction. The experience gained during the first employment of this method at the lake "Katja", a residual lake of lignite stripping, is presented in this paper.

  12. Contraception and abortion in Romania.

    Johnson, B R; Horga, M; Andronache, L


    After the downfall of the Ceausescu regime in December, 1989, the new Government of Romania abolished the law that prohibited abortions on request. Subsequently, the rate of legally induced abortions increased significantly while the rate of maternal mortality declined dramatically. Despite the large number of women who request induced abortions, most women and gynaecologists say that they would prefer to prevent unwanted pregnancies through the use of modern contraception. In this paper we examine factors that contribute to the disparity between women's desire to use modern contraception to prevent unwanted pregnancies and their practice of having induced abortions to prevent unwanted births. The results show that women (and suggest that men) need a wide choice of dependably available high-quality contraceptives; they need to be able to obtain information, counselling, and methods from a wide range of sources/health-care providers; both women's and men's perceptions about, and use of, modern contraception could be positively affected through sexual education started in secondary school; and, to reduce repeat abortions, women's post-abortion family-planning needs must not be neglected.

    Full Text Available Capital market offers those who study it and those who use it as traders or as investors, a feature similar to a paradox. Her specific routine operations are regulated to the level of detail bylaws, instructions, procedures or measures layouts while decisions on investments in securities and portfolio restructuring are taken under perpetual uncertainty. This has a twofold explanation, an objective one and a subjective one.Future prices, as well as successive conditions of stock exchange not necessarily flow from the past, thus one cannot predict their level and over them is hanging the conviction that any selected alternative action is probably the best without having any certainty that that is really correct and rational in an absolute mode.Even if the evaluation of factors influencing prices is a questionable one, there is the likelihood of good choices when doing a basic operation-selling or buying. Factors identified, evaluated and ranked may change in the next period their force of action or even the market structure so that exchange activity is at least difficult to determine.In this category is included the mutual fund industry, whose evolution in Romania was not without risk and has had a tortuous circuit thanks to immature capital markets and market actors but especially due to the permissive legislation during the start phase. A certain progress was recorded in the last 10 years,although the financial crisis made its mark on the capital market and revealed the negative impact of systemic risks.

  14. Evaluation of endometrial cancer epidemiology in Romania.

    Bohîlțea, R E; Furtunescu, F; Dosius, M; Cîrstoiu, M; Radoi, V; Baroș, A; Bohîlțea, L C


    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.

  15. Studies on the Environmental Improvement in Romania

    Ogaki, Mitsuharu; Yoshizumi, Koji; Motonaka, Junko; Yabutani, Tomoki; Nakamoto, Yumi; Stanescu, Rodica; Plesca, Marinela

    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.

    Full Text Available The process of preparation and adoption of the European single currency is one of the most important challenges that Romania has to face in the first decade as a full time member of the European Union. This process will test both the political and the administrative capacity, requiring very clear programs for the adaptation of European regulations and directives that will ensure real and nominal convergence. This process will surely prove to be a difficult one and it will bring a high degree of pressure upon the economic system in general. The worldwide financial crisis is making the process of single European currency adoption even more difficult for Romania. Although its effects are not directly felt in Romania, the disorder created within international markets can easily transform the management of economic and currency politics into an insecure and extremely difficult task.

Gains and losses (I" where we have been presented statistics on Romania's trade with major trading partners to whom, before, or after EU accession, the legal status has changed. In this paper we try to identify the benefits and costs of accession to the EU in terms of trade. In the first part we analyze the dynamics of trade with new partners, resulting from the accession. The last part is devoted to conclusions. The main idea that emerges from this work is that, unfortunately, Romania governors, did not know to take advantage of the opening to the biggest economic market although the financial and institutional support offered by the EU.

    Full Text Available The main objective of this paper is to evaluate the sustainability of public finance in Romania and to explore the fiscal threats Romania might face in the future. A sound fiscal policy implies avoiding excessive liabilities of the government, but at the same time delivering the proper public goods and services, including the necessary safety net in times of crisis. An unsustainable fiscal position negatively impacts on macroeconomic stability; moreover, if public finances are perceived to be unsustainable in the long run, the reaction of the international financial markets could generate a fiscal crisis, which might surprise the fiscal planners. The main findings of the paper are the following: i according to the multidimensional approach of the European Commission, in the short run, it seems that Romania is free from fiscal stress, there is a low risk in the medium term, and in the long run the risk becomes medium; ii a potential medium-term fiscal sustainability risk derives from the accumulation of losses and arrears in the business and companies sectors in which the state is a majority shareholder; iii Romania records one of the lowest budget revenues to GDP ratios in EU, while the Romanian tax system is characterized by a poor tax collection, inefficient administration and excessive bureaucracy; iv the structure of public spending in Romania is characterized by the predominance of wage spending and social assistance, while the poor state of the public pension system is an important vulnerability of the public finance position; v overall, the degree of tax compliance in Romania was only 55.8% in 2013, and according to the calculations made by the Fiscal Council, tax evasion represented 16.2% of GDP in 2013. All these aspects make up a grim picture of sustainability of public finances, which has to be considered by the public decision makers regarding future fiscal policy actions.

    Full Text Available The transition to an economy that operates on market principles represents a period of profound changes based on redefining the paradigms of development. After more than 20 years from the 1989 events, Romania has already completed some important steps towards an open market economy. The path to this main objective was sinuous, with frequent acceleration and stumbling. This paper offers a view of the complex process of privatization in Romania after the fall of the communist regime, with a detailed approach on the transition process as well. The accent falls on the economic development of the country during the mentioned period.

Some practical conclusions and recommendations are presented considering the need for further contract studies.

  1. Renewable Energy in Romania after 2007

    Daniela Enachescu


    Full Text Available Sustainable development requires obtaining energy from alternative sources which are clean and sustainable. In Romania, there are categories of renewable energy that basically were not used, such as solar PV and wind energy by 2007. Even today, their share is minor compared to energy from conventional sources, but they were made important steps, including in legislation domain. The paper aims to present the evolution of renewable energy in Romania after 2007, as a result of EU integration. The analysis is done separately for installed capacity in the following chapters: Hydropower, Wind Onshore, Solid biomass, Solar Photovoltaic and Biogas.

    Full Text Available If we were to consider that Romania was formed by the unification of provinces that experienced a strong unity through culture, language, religion, as well as through the intense trade relations existing between them over time, we may say that our country has an important historical experience regarding regionalisation. After 1989, Romania underwent a radical change of economic and political organisation (from a centralised economy to a free, market economy and the approximation to the Western economic structures, the European Union (EU. Under these conditions the national authorities had to take into account the principles and the organisation and functioning of the European capitalist economies. During the communist period, Romania had an administrative-territorial and economic organisation that favoured centralised decision making. In the case of market economies, organisation allows and encourages the decentralisation of decision making. In the mid '90s, the economic and social realities of Romania lead to the achieving of the regionalisation of the national territory in accordance with the subsidiarity principle of the EU. Regionalisation sought to identify the most appropriate spatial and territorial framework for guiding the economic development processes, by facilitating the use of tools and resources provided by the European Union. The regional development policy is a continuation of the policies of national economic growth and development, both aiming at improving the economic and social life of the national communities. The final aim of this paper is to identify the economic and social situation of the development regions in Romania. The study provides insight into Romania's relations with the European Union, with regard to the access and use of the pre-accession European funds. Furthermore, the paper achieves a qualitative analysis, through a positive approach, but also a quantitative one of the economic and social situation of each

  3. Transmissibility-Based Operational Modal Analysis: Enhanced Stabilisation Diagrams

    Gert De Sitter


    Full Text Available Recently it has been shown that also transmissibilities can be used to identify the modal parameters. This approach has several advantages: because of the deterministic character of the transmissibility functions, the estimated parameters are more accurate than the results obtained with the power spectra based operational modal analysis techniques. Another advantage is that the transmissibility functions do not depend on the colouring of the unknown forces. A disadvantage of the transmissibility based operational modal analysis techniques is that non-physical modes show up in the stabilisation diagrams. In this contribution it will first be shown that those non-physical modes will show up when traditional stabilisation diagrams are used. In a second step, a new approach of selecting the physical modes out of a set of estimated modes will be discussed and the new approach will be validated using data generated with an acoustical Finite Element Model. Finally, the approach will be validated using real acoustical data.

    Full Text Available Ecofeminism can be understood as the relationship between the manner in which women are treated in society and on how the environment is treated and protected. Ecofeminism starts from the idea according to which "nature is a feminist issue". The explanation for this is based on the feminist philosophy according to which the connection between woman and nature is a strong one, due to the fact that she is the one who gives birth, thus helping nature to regenerate itself. Without women, female plants and animals, the planet could not develop, perpetuate and the end would be death. Furthermore, another explanation related to the first is that animals and people in their capacity as mothers are able to provide a greater amount of love, care, protection, both to their offspring and to nature. This paper aims to analyze the manner in which women are harmed by the environmental degradation in Romania and also the principles that have governed and still govern the current economy. Nowadays society is lead largely by male gender persons. The main accusations against current policies is that they seek concrete and immediate results, such as those related to economic growth, inflation rate etc. in terms of strictly economic indicators such as: gross domestic product, net national product, gross national product etc.. On the contrary, ecofeminist policies suggest that the emphasis should be placed on quality of life issues, which within itself analyzes both economic and also social and environmental aspects. Is not this the reproach for decades now that is brought to current economic policies? The fact that they do not take into account issues related to environmental degradation, in time led to negative consequences in the world whose costs are unimaginable.

  5. The Aromanians in Contemporary Romania



    Full Text Available Romanians are one of the native people from this part of Europe, the only heirs of the eastern Roman Empire. Romanians were born, as showed in historical and linguistic studies, on both sides of the Danube River, an ethnical continuity on both banks of the river, until the Slav people arrived in the 6th and 7th centuries AD. The political situation created after the First World War caused serious problems for the Aromanians in the newly created Balkan states. There were substantial population exchanges among the Balkanic countries (Greece, Turkey, Bulgaria. This situation led to the change of the ethnic composition in these countries There were three main emigration centers: Meglenia, Veria and Vodena. The idea of the Macedo-Romanians' migration to Cadrilater represents a consequence of the demographic pressure put on the Aromanian population living in Greece. The difficulties, which appeared, caused the migration to Cadrilater of an important Aromanian segment (more than 25 000, between 1925 and 1933. But these circumstances did not mean the end of their tragedy because they were displaced to Constanţa and Tulcea when territory in Cadrilater was ceded to Bulgaria (September 1940. In Dobrudja, the Macedo-Romanians are a linguistic and cultural community, but, at the same time, south-Danubian Romanians, due to hostile historical events, were forced to settle here. In their native lands, they were in contact with other Balkan people, being separated from the body of Carpathian and Danubian Romanianhood. Looking after sheep, carrying merchandise and trading were the main issues that shaped the common ethnic and linguistic aspects of survival on both sides of the Danube River. The paper is focused upon the situation and specific problems of the Aromanians living in contemporary Romania.

  6. The mediation procedure in Romania

    Alexandrina Zaharia


    Full Text Available The mediation activity as an alternative way of solving conflicts occupies an important place in modernsociety. Currently, the mediation reached its maturity worldwide being adopted without reservations.The future of solving conflicts is undoubtedly closely related to mediation. XXth century is the century of solvingconflicts amiably outside the court room. In Romania and the mediation profession were regulated by the Law no.192/2006, on the basis of the idea that mediation is one of the major themes of the reform strategy of the judicialsystem 2005-2007. By adopting the mentioned law it was followed the idea of reducing the volume of activitycourts, and therefore, relieve them of as many cases, with the direct effect on the quality of justice. Mediation is avoluntary process in which the parties with a neutral and impartial third party, without power of decision - themediator - who is qualified to assist the parties to negotiate, facilitating the communication between them andhelping them to reach a unanimous effective and sustainable agreement. The parties may resort to mediation beforeor after triggering a trial. Mediation can be applied, in principle, on any type of conflict. However, theRomanian legislator has established special stipulations on conflict mediation in criminal, civil and familylaw. Although not expressly provided, the stipulations regarding the civil conflicts and also apply to commercialconflicts. Therefore, the mediation is applicable to most types of lawsuits, except those relating to personalrights. As a "win- win" principle, the mediation does not convert any of the parties defeated or victorious; allthose involved have gained by applying this procedure.

  7. Lactose fermentation at Camembert, made by classic and stabilised

    Bogdan Perko


    Full Text Available In our experiments the fermentation of lactose at Camembert type cheese by classic and stabilised technology was monitored. In each of the two technologies two experiments were made. The difference between these two technologies is in pH level, which drops below 5 by classic technology and remains above 5 by stabilised technology at all times. To achieve the criteria of stabilised technology the fermentation was stopped at a desired level of pH, by dropping the cheese in brine at 14 °C. After salting and moulding cheesewas transferred from the first three experiments into a ripening chamber at 11 °C. With the last experiment (stabilised technology the cheese ripened for 3 days at 5 °C. During ripening process pH dropped below 5 in all experiments. The process of fermentation was performed by the following lactic acid bacteria: Streptococcus thermophilus, Lactococcus lactis subsp. lactis and Lactococcus lactis subsp. cremoris. As these lactic acid bacteria ferment differently D-galactose during manufacture and ripening process, the contentof lactose and D-galactose was measured. Based on the results of our research the following conclusion can be made: the action of lactic acid bacteria can not be stropped even at 5 °C. The native microflora, which remains in the milk after thermisation, might be responsible for the fermentation of Dgalactose. It could be possible that the Streptococcus thermophilus enzymes were not inactivated, causing continuation of lactose fermentation even at low temperature. Mesophilic lactococci were inhibited and for that reason Dgalactose accumulated in cheese. Only after cheese were transferred into a ripening chamber at 11 °C and with low lactose concentration in medium left, mesophilic lactococci started to ferment D-galactose.

  8. From stringy particle physics to moduli stabilisation and cosmology

    Honecker, Gabriele [Institute for Physics (WA THEP) and Cluster of Excellence PRISMA, Johannes Gutenberg University, Mainz (Germany)


    Intersecting D6-branes provide a geometrically intuitive road to stringy particle physics models, where D6-branes stuck at orbifold singularities can lead to the stabilisation of deformation moduli, and the QCD axion can arise from the open string sector in a very constrained way compared to pure field theory. We demonstrate this interplay of different physical features here through an explicit model. (copyright 2016 WILEY-VCH Verlag GmbH and Co. KGaA, Weinheim)

  9. [A difficult stabilisation. Chlorpromazine in the fifties in Belgium].

    Majerus, Benoît


    Through a Belgian case study the article tries to trace the gradual stabilisation of chlorpromazine as an antipsychotic in the 1950s. By varying ranges and angles of approach it shows the heterogeneity of actors involved and the semantic bricolage that accompany the marketing of the first antipsychotic. Far from being a revolution, the presence of Largactil in psychiatric practice is rather characterised by integration into a wider range of medicines and sinuous searching to give sense to this new drug.

    The use of external feedback to stabilise the frequency of a tapered laser during current pulsing is reported. Using this technique more than 20 W of peak power in 60 ns pulses from the tapered laser is obtained and owing to the external feedback, the laser is tunable in the 778-808 nm range....... The spectral width of the tapered laser is significantly narrowed compared to the freely running laser....

    Cenoz, S.; Hernandez, J.; Gangutia, N.


    This work describes the use of Low-Grade MgO as a stabiliser agent for polluted soil reclaim. Low-Grade MgO may be an economically feasible alternative in the stabilisation of heavy metals from heavily contaminated soils. The effectiveness of Low-Grade MgO has been studied in three ex-situ stabilisation of heavily polluted soils contaminated by the flue-dust of pyrite roasting. LG-MgO provides an alkali reservoir guaranteeing long-term stabilisation without varying the pH conditions. The success of the ex-situ stabilisation was corroborated with the analysis of heavy metals in the leachates collected from the landfill o ver a long period of time. The study also includes the results obtained in an in-situ pilot scale stabilisation of contaminated soil. (Author) 17 refs.

  12. Preliminary stabilisation of stormwater biofilters and loss of filter material.

    Subramaniam, D N; Mather, P B

    Stabilisation affects performance of stormwater biofilters operating under intermittent wetting and drying, mainly due to wash-off of filter material. Understanding the dynamics of solids wash-off is crucial in designing stormwater biofilters. The current study analysed the dynamics of solids wash-off in stormwater biofilters and quantified the loss of solids from the filter. Four Perspex™ bioretention columns (94 mm internal diameter) were fabricated with a filter layer that contained 8% organic material and were fed with tap water with different numbers of antecedent dry days (0-40 day) at 100 mL/min. Samples were collected from the outflow and tested for particle size distribution and total solids and turbidity. Solids of particle size less than 50 microns were washed off from the filter during the stabilisation period, indicating that no sand particles were washed off. The very first event after commissioning the filter resulted in the highest wash-off of solids (approximately 75 g of fines) while a significant drop in wash-off followed from the second event. An empirical model fitted to the data showed that preliminary stabilisation of a filter occurs in the first three events, during which almost 25% of fines are lost from the filter.

  13. Non-overshooting stabilisation via state and output feedback

    Halikias, G.; Papageorgiou, A.; Karcanias, N.


    The concept of 'strong stability' of linear time-invariant (LTI) systems has been introduced in a recent paper (Karcanias, N., Halikias, G., and Papageorgiou, A. (2010), 'Strong Stability of Internal System Descriptions', International Journal of Control, 83, 182-205). This is a stronger notion of stability compared to alternative definitions (e.g. stability in the sense of Lyapunov, asymptotic stability), which allows the analysis and design of control systems with non-overshooting response in the state-space for arbitrary initial conditions. This article reviews the notion of 'strong stability' (Karcanias et al. 2010) and introduces the problem of non-overshooting stabilisation. It is shown that non-overshooting stabilisation under dynamic and static output feedback are, in a certain sense, equivalent problems. Thus, we turn our attention to static non-overshooting stabilisation problems under state-feedback, output injection and output feedback. After developing a number of preliminary results, we give a geometric interpretation to the problem in terms of the intersection of an affine hyperplane and the interior of an open convex cone. A solution to the problem is finally obtained via linear matrix inequalities, along with the complete parameterisation of the optimal solution set.

  14. Interplay between body stabilisation and quadriceps muscle activation capacity.

    Bampouras, Theodoros M; Reeves, Neil D; Baltzopoulos, Vasilios; Maganaris, Constantinos N


    The study aimed to distinguish the effect of stabilisation and muscle activation on quadriceps maximal isometric voluntary contraction (MVC) torque generation. Nine subjects performed (a) an MVC with restrained leg and pelvis (Typical MVC), (b) a Typical MVC with handgrip (Handgrip MVC), (c) an MVC focusing on contracting the knee extensors only (Isolated knee extension MVC), and (d) an MVC with unrestrained leg and pelvis (Unrestrained MVC). Torque and activation capacity between conditions were compared with repeated measures ANOVA and dependent t-tests. EMG (from eleven remote muscles) was compared using Friedman's and Wilcoxon. Typical MVC (277.2±49.6Nm) and Handgrip MVC (261.0±55.4Nm) were higher than Isolated knee extension MVC (210.2±48.3Nm, pMVC (195.2±49.7Nm, pMVC (83.1±15.9%) activation was higher than Isolated knee extension MVC (68.9±24.3%, pMVC and Handgrip MVC (81.8±17.4%) were higher than Unrestrained MVC (64.9±16.2%, pMVC consistently lower than Typical MVC or Handgrip MVC. Stabilisation of the involved segments is the prime concern allowing fuller activation of the muscle, reinforcing the need for close attention to stabilisation during dynamometry-based knee joint functional assessment.

  15. Preparing Stabilisation for 21st Century Security Challenges

    Steven A. Zyck


    Full Text Available Stabilisation, as a concept and set of practices, has proliferated over the past two decades and is now implicitly integrated into a range of global frameworks. However, this enthusiasm has at times risked turning this increasingly common, albeit contested, idea into a piece of jargon that discounts its unique facets: a focus on all sorts of violence, not just conflict, that create political instability and human harm and a problem-solving approach that draws selectively on various forms of intervention (e.g., statebuilding, counterinsurgency, peacekeeping, etc. without being beholden to any one toolkit. The pragmatism inherent within the concept of stabilisation will grow increasingly important as new security challenges emerge or proliferate. These include the fragmentation and regionalisation of conflict systems, transnational organised crime, large-scale migration and new, disruptive technologies. Novel approaches rooted in big data and technology will increasingly need to be applied. Most importantly, in foreign policy, military and development communities often driven by perceptions about what causes, ends or prevents violence, stabilisation must maintain its agnostic, problem-solving roots and allegiance to evidence over ideology.

  1. Religion and political identification in Communist Romania

    Rada Cristina IRIMIE


    Full Text Available The Orthodox Church has played, from the beginning of the twentieth century, a vital role in building the political architecture of the Romanian state. The establishment of a communist regime in Romania after World War I created a new modus vivendi between Church and State, and placed the Romanian Church’s activities under strict government supervision. This article will look at the role of the religion in the ethnic identity of Romanians, during the communist times. A historical outlook is necessary in understanding the foundation of religion in the Romanian state, thus the article provides a brief background on the role of the Church in the modern Romanian history. Then, the article will examine the unique norms of cooperation between religion and national communism built in Romania, during that period. Subsequently, this will help us observe the interplay between religion and ethnicity evidenced in communist Romania. The cases of the Serbian and the Lipovan Russian communities feature the complexity of this interaction. The goal of this paper is to offer an understanding of the relationship between religious and ethnic identities in Romania, during this particular period.

    Full Text Available In the context of globalization, sustainable development is the key to the development of contemporary society and future generations. Sustainability has become a key point for the debates in the political, economic, and academic environment. Therefore, today wehave reached the point when we speak of a country or company sustainability, of environmentalor agricultural sustainability, while speaking,at the same time, of fiscal policy sustainability. The purpose of this paper is to analyze the Romanian fiscal policy sustainability in terms of tax revenues. The methodology used in this research is bibliographical analysis of specialist literature and statistical analysis of data. Bibliographical analysis was used to define operating concepts: fiscal sustainability and tax revenues. Statistical analysis was used to analyze the evolution of tax revenues in Romania between2005and2013, as well as the share of tax revenues in the general consolidated budget of Romania. Statistical data were processed using Microsoft Excel and presented as evolution diagrams. The novelty and originality of the present work consist in the bibliographical study on Romanian fiscal policy sustainability, the statistical study on the evolution of tax revenues in Romania between 2005and2013, and the analysisof fiscal policy sustainability in Romania in terms of tax revenues.

Through this debate I intend to bring out a picture concerningthe evolution of “retail“ in the last years in Romania, to outline the retail sectorat this moment and eventually to anticipate the tendencies which will bepresent in the Romanian retail sector in perspective. The last years havebrought especially important changes in the retail sector in Romania. Thechanges began to more obviously manifest after Romania’s adhesionbecame a certainty. The results from numerous researches in retail revealthe evolution of new types of commerce in the detriment of those representedby traditional commerce and implicitly the change in the structure of the localretail. Trough this paper I seek to portray an x-ray of the evolution of retail inRomania of the last years, to underline the retails’ sector actual state, also toanticipate the tendencies that will manifest in the Romanian retail sector inthe near future.

  8. Latest climate changes in Romania :tornadoes

    Pop, Elena


    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

  9. The Relations Between Romania and European Union (1993-2003

    Adrian IVAN


    Full Text Available With the collapse of the communism regimes in central and eastern Europe, the states from this area, among which Romania, expressed their aspiration to integrate in the big European family represented by the European Union. In this respect the European Union proposed “association agreements” to these countries, agreements to which Romania adhered in February 1993 (in 1995 Romania presented its request for admission in the EU. Further on, in 1997 Romania launched “The national program for the adoption of the acquis comunautaire”. An important moment for Romania has arrived at Helsinki during the meeting of the European Council (10-11 December 1999, which decided to organize bilateral intergovernmental conferences for all the 13 candidate states in order to begin the accession negotiations, which were opened by Romania on the 16th of February 2000. The Helsinki decision regarding the beginning of the admission negotiations with Romania was a political one; Romania having acute economical, juridical and administrative problems. In the European Commission 2003 country report regarding Romania, there are positive appreciations with regard to the fulfillment of the political criteria and for the progress made in the adoption of the acquis comunautaire as well as for the economical progress but Romania still did not receive the statute of functional market economy. On the other hand the malfunctions still persist in the domains of public administration, agriculture, justice and the fight against corruption.

  10. Is Romania Heading Towards a Presidential Republic?

    Claudia Gilia


    Full Text Available The study focuses on the issue of semi-presidential regime in Romania. Political events in recent years have highlighted major deficiencies in the functioning of public authorities in Romania. The balance of powers provided expresis verbis in the Constitution proved to be rather a pronounced imbalance. The option of the Romanian Constituent Assembly in 1991 for a semi-presidential republic has been questioned lately. In our study, we show the characteristics of semi-presidential system in terms of Romanian constitutional provisions and political experiences. The semi-presidential system in Romania was and still is subject to continuous public debates, and it is also an electoral issue, as we speak, between the political parties involved in electoral campaign. For the present research, we have used both the analytical and comparative approach. The study is relevant for the public law experts, as well as for the political authorities because it displays an image of the current semi-presidential system. We believe that a possible option for a presidential regime in Romania is not viable, but rather a clarification of the duties of each public authority would be the best solution for the recovery of the Romanian constitutional system. The study is relevant for the public law experts, as well as for the political authorities because it displays an image of the current semi-presidential system. Our conclusions regarding the evolution of semi-presidential system in Romania can be considered an onset for those who will draft the new Romanian constitutional design.

  12. Epidemiological review of toxoplasmosis in humans and animals in Romania.

    Dubey, J P; Hotea, I; Olariu, T R; Jones, J L; Dărăbuş, G


    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.

  13. Preferences of the Proctodrilus species (Lumbricidae: Oligochaeta on a slope of the lower 'Kokel' uplands in Romania.

    Höser, N.


    Full Text Available Romania. On a slope in the 'Kokel' uplands in Romania (Transylvanian Piedmont at the foot of the eastern Carpathians the earthworm species Proctodrilus tuberculatus (Černosvitov, 1935, P. thaleri Höser & Zicsi, 2009 and P. opisthoductus Zicsi, 1985 were found at different points in the soil catena. The colluvial soil clearly has the distinctive characteristics of an inverse profile. P. tuberculatus occurs at the top of the slope and in the colluvial soil, while P. thaleri was found exclusively in the area at the foot of the slope towards the valley, in the section of greater colluvial horizon diversity. P. opisthoductus occurs towards the valley floor, in the relatively humus-rich mineral layer of the inverse profile. The pedological findings indicate that P. tuberculatus prefers the leached horizons of the lessived soils. Where P. thaleri occurs is a colluvial soil with a probable tendency to a soil-type interference of lessive soil and brown loam (terra fusca, where these two types are within one and the same soil profile. Possibly the sedimentary lessivage complexes of a terra fusca character (plasma flow make it easier for the Proctodrilus species to move through the solum.

  14. Self-Stabilising Quadrupedal Running by Mechanical Design

    Panagiotis Chatzakos


    Full Text Available Dynamic stability allows running animals to maintain preferred speed during locomotion over rough terrain. It appears that rapid disturbance rejection is an emergent property of the mechanical system. In running robots, simple motor control seems to be effective in the negotiation of rough terrain when used in concert with a mechanical system that stabilises passively. Spring-like legs are a means for providing self-stabilising characteristics against external perturbations. In this paper, we show that a quadruped robot could be able to perform self-stable running behaviour in significantly broader ranges of forward speed and pitch rate with a suitable mechanical design, which is not limited to choosing legs spring stiffness only. The results presented here are derived by studying the stability of the passive dynamics of a quadruped robot running in the sagittal plane in a dimensionless context and might explain the success of simple, open loop running controllers on existing experimental quadruped robots. These can be summarised in (a the self-stabilised behaviour of a quadruped robot for a particular gait is greatly related to the magnitude of its dimensionless body inertia, (b the values of hip separation, normalised to rest leg length, and leg relative stiffness of a quadruped robot affect the stability of its motion and should be in inverse proportion to its dimensionless body inertia, and (c the self-stable regime of quadruped running robots is enlarged at relatively high forward speeds. We anticipate the proposed guidelines to assist in the design of new, and modifications of existing, quadruped robots. As an example, specific design changes for the Scout II quadruped robot that might improve its performance are proposed.

  15. Oil-in-oil emulsions stabilised solely by solid particles.

    Binks, Bernard P; Tyowua, Andrew T


    A brief review of the stabilisation of emulsions of two immiscible oils is given. We then describe the use of fumed silica particles coated with either hydrocarbon or fluorocarbon groups in acting as sole stabilisers of emulsions of various vegetable oils with linear silicone oils (PDMS) of different viscosity. Transitional phase inversion of emulsions, containing equal volumes of the two oils, from silicone-in-vegetable (S/V) to vegetable-in-silicone (V/S) occurs upon increasing the hydrophobicity of the particles. Close to inversion, emulsions are stable to coalescence and gravity-induced separation for at least one year. Increasing the viscosity of the silicone oil enables stable S/V emulsions to be prepared even with relatively hydrophilic particles. Predictions of emulsion type from calculated contact angles of a silica particle at the oil-oil interface are in agreement with experiment provided a small polar contribution to the surface energy of the oils is included. We also show that stable multiple emulsions of V/S/V can be prepared in a two-step procedure using two particle types of different hydrophobicity. At fixed particle concentration, catastrophic phase inversion of emulsions from V/S to S/V can be effected by increasing the volume fraction of vegetable oil. Finally, in the case of sunflower oil + 20 cS PDMS, the study is extended to particles other than silica which differ in chemical type, particle size and particle shape. Consistent with the above findings, we find that only sufficiently hydrophobic particles (clay, zinc oxide, silicone, calcium carbonate) can act as efficient V/S emulsion stabilisers.

    Waste stabilisation ponds (WSP) are the preferred method for treatment of urban wastewater in low-income countries but, especially in arid regions, the pond systems can be important breeding sites for mosquitoes of medical importance. In a WSP system in Faisalabad, Pakistan, we assessed the impact...... of simple environmental interventions on mosquito occurrence and abundance. Reducing the amount of floating matter in the ponds, eliminating emergent vegetation and repairing cracks in the cement structure reduced the number of mosquito-positive samples in the intervention ponds to almost zero, whereas...

  20. Nordic regionalisation of a greenhouse-gas stabilisation scenario

    Wyser, Klaus; Rummukainen, Markku; Strandberg, Gustav


    The impact of a CO{sub 2} stabilisation on the Swedish climate is investigated with the regional climate model RCA3 driven by boundary conditions obtained from a global coupled climate system model (CCSM3). The global model has been forced with observed greenhouse gas concentrations from pre-industrial conditions until today's, and with an idealised further increase until the stabilisation level is reached. After stabilisation the model integration continues for another 150+ years in order to follow the delayed response of the climate system over a period of time. Results from the global and regional climate model are compared against observations and ECMWF reanalysis for 1961-1990. For this period, the global model is found to be too cold over Europe and with a zonal flow from the North Atlantic towards Europe that is too strong. The climate of the driving global model controls the climate of the regional model and the same deviations from one are thus inherited by the other. We therefore analyse the relative climate changes differences, or ratios, of climate variables between future's and today's climate. Compared to pre-industrial conditions, the global mean temperature changes by about 1.5 deg C as a result of the stabilisation at 450 ppmv equivalent CO{sub 2}. Averaged over Europe, the temperature change is slightly larger, and it is even larger for Sweden and Northern Europe. Annual mean precipitation for Europe is unaffected, but Sweden receives more precipitation under higher CO{sub 2} levels. The inter-annual and decadal variability of annual mean temperature and precipitation does not change with any significant degree. The changes in temperature and precipitation are not evenly distributed with the season: the largest warming and increased precipitation in Northern Europe occurs during winter months while the summer climate remains more or less unchanged. The opposite is true for the Mediterranean region where the precipitation decreases

    Full Text Available The article examines the question of secularization of Europe, and in particular of Romania, by using multiple international data sets. Secularization has been defined separation of the state government and religious authority resulting in a decrease in church attendance, a diminished trust in religious institutions, a lessening of religions’ importance in society, an increase in religious diversity with a concomitant decrease in group cohesiveness, and the rise of situational ethics and moral relativism. Several theories of secularization are explored in an effort to determine the presence of a secular continuum. Although there may be an increase of secular behaviours in member states of the European Union, a claim of growing secularism in Romania is not supported by an examination of the multiple data sets

  5. Place branding: a challenging process for Romania

    Daniela Dumbraveanu


    Full Text Available In a world of globalization, the marketing of places has grown in importance as countries, regions and individual destinations such as cities compete with one another to attract investment and visitors. With Romania becoming a European Union country since 2007, marketing itself as a country with identity and personality is of crucial importance when considering competition. In order to compete effectively, it is essential to identify the critical success factors and ensure these are incorporated into one’s strategic planning. Place and destination marketing indicate that image and identity play an important role in differentiating between similar alternatives. This paper is focussing on action undertaken so far by both Romania and Bucharest, presenting experts opinion and comments on results, assessing the stage and situation as it is at present.

    Full Text Available Taxation is a historical result of the social, political and economic environment in a state. At the same time, the development of a state depends a lot on the history of its own tax system, on the way it is conceived and operates. The establishment of budgetary incomes has to be made in accordance with the requirements related to yield, efficacy, equity. The plurality of these tasks as well as political, economical, administrative constraints have materialized in the application of a gradual reform in Romania after passing to market economy. Its application has not always had the foreseen effects, repeated legislative alterations leading to investors’ discouraging and to difficult enforcement of the legislation at the level of economic agents and fiscal bodies. The paper presents aspects of direct taxation on the economic environment from Romania as well as comparisons with the state of the European Union.

  9. Education and labour market outcomes in Romania



    Full Text Available Education plays a central role in preparing individuals to enter the labour market, by offering them the opportunity to improve and increase their amount of knowledge, skills and abilities. Considering this aspect, the purpose of our study is to identify and analyse the relationship that exists between the educational stock, as a measure of the quality, quantity and availability of human resources, and the labour markets’ outcomes in Romania. In order to reach this goal, we have conducted an analysis of the secondary data offered by the specialized literature. These secondary sources included various statistical yearbooks and reports, as well as different scientific researches. The results of our study show that, in Romania, the level of education is positively linked not only to the employment rate but also to the income level.

  13. Diversity and distribution of reptiles in Romania

    Dan Cogălniceanu


    Full Text Available 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.

  14. Diversity and distribution of amphibians in Romania

    Dan Cogălniceanu


    Full Text Available Nineteen species of amphibians inhabit Romania, 9 of which reach their range limit on this territory. Based on published occurrence reports, museum collections and our own data we compiled a national database of amphibian occurrences. We georeferenced 26779 amphibian species occurrences, and performed an analysis of their spatial patterns, checking for hotspots and patterns of species richness. The results of spatial statistic analyses supported the idea of a biased sampling for Romania, with clear hotspots of increased sampling efforts. The sampling effort is biased towards species with high detectability, protected areas, and large cities. Future sampling efforts should be focused mostly on species with a high rarity score in order to accurately map their range. Our results are an important step in achieving the long-term goals of increasing the efficiency of conservation efforts and evaluating the species range shifts under climate change scenarios.

  4. Perception of Organic Food Consumption in Romania

    Petrescu, Anca Gabriela; Oncioiu, Ionica; Petrescu, Marius


    This study provides insight into the attitude of Romanian consumers towards organic food. Furthermore, it examines the sustainable food production system in Romania from the perspective of consumer behavior. This study used a mathematical model of linear regression with the main purpose being to determine the best prediction for the dependent variable when given a number of new values for the independent variable. This empirical research is based on a survey with a sample of 672 consumers, which uses a questionnaire to analyze their intentions towards sustainable food products. The results indicate that a more positive attitude of consumers towards organic food products will further strengthen their purchasing intentions, while the status of the consumption of organic consumers will not affect their willingness to purchase organic food products. Statistics have shown that sustainable food consumption is beneficial for health, so it can also become a profitable business in Romania. Furthermore, food sustainability in Romania depends on the ability of an organic food business to adapt to the new requirements of green consumption. PMID:28556795

  5. Aging in Romania: research and public policy.

    Bodogai, Simona I; Cutler, Stephen J


    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.

  6. Romania as Participant in the Globalization Process

    Sergiu-Lucian Sorcaru


    Full Text Available The objective of the paper is to present the EU policies, how they relate with Member States and with its partners, the multiculturalism has never been an impediment, but it has made it special, mentioning here the economic level, where the Union has the highest GDP per capita in the world. Our intention is to present the components of globalization, a phenomenon that is the basis for the European Union and the sudden evolution of Romania in the recent years. Romania was integrated in the globalization process and took advantage of all the benefits of this engine of the modern world. The result lies in a better understanding of EU policies and its effects on the Romanian economy. In this paper we have achieved an analysis of non-refundable grants offered by the European Union for the period 2007-20013 and how they helped the industrial and social development of Romania. The added value of the scientific interpretation of the Romanian situation at economic level is highlighted by the beneficial influence of the European space, opening towards a global market and the original approach in economic terms of the development analysis and participation in the globalization process.

  7. Perception of Organic Food Consumption in Romania.

    Petrescu, Anca Gabriela; Oncioiu, Ionica; Petrescu, Marius


    This study provides insight into the attitude of Romanian consumers towards organic food. Furthermore, it examines the sustainable food production system in Romania from the perspective of consumer behavior. This study used a mathematical model of linear regression with the main purpose being to determine the best prediction for the dependent variable when given a number of new values for the independent variable. This empirical research is based on a survey with a sample of 672 consumers, which uses a questionnaire to analyze their intentions towards sustainable food products. The results indicate that a more positive attitude of consumers towards organic food products will further strengthen their purchasing intentions, while the status of the consumption of organic consumers will not affect their willingness to purchase organic food products. Statistics have shown that sustainable food consumption is beneficial for health, so it can also become a profitable business in Romania. Furthermore, food sustainability in Romania depends on the ability of an organic food business to adapt to the new requirements of green consumption.

  9. Comparative Assessment of Stabilised Polybutadiene Binder under Accelerated Ageing

    Luiz Felipe Cannaval Sbegue


    Full Text Available Polybutadiene elastomers are versatile materials, being employed at several applications from rocket propellant binder to adhesives and sealants. The elastomers derived from hydroxyl-terminated polybutadiene are usually stabilised with antioxidants to prevent degradation. In this study, a comparative assessment among 2,2’-methylene-bis (4-methyl-6-tert-butylphenol (AO2246, 2,6-di-tert-butyl-4-methylphenol (BHT, p-phenylenediamine (pPDA, and triphenylphosphine (TPP regarding stabilisation of hydroxyl-terminated polybutadiene binder under accelerated ageing (six months at 65 °C was carried out. Evaluation of antioxidants effectiveness was examined through Oxidation Induction time, sol/gel extraction, swelling and mechanical testing, dynamic mechanical analysis, and mass variation measurement. AO2246 yielded the best performance, meanwhile BHT was poorly protective. TPP acted as prooxidant, causing a severe degradation of the binder, and pPDA was not manageable to be assessed due to the lower curing degree of the resulted polyurethane.

  10. Design for the Control of a Rotatable Stabiliser

    Childs, S J


    This research sets out a design for the control of a rotatable stabiliser which, it is proposed, might augment, or fully replace, the conventional control mechanisms for pitch and yaw in aircraft. The anticipated advantages of such a device are around 25% less drag, for a capability which ranges between equivalent and greater than twofold that of the conventional tail. One, anticipated handicap of such a device is the potential for it to stall, from its tips, inward, if rotated too fast. For succinctness, a mapping betweeen states of the device and the position of a two-axis controller (e.g. a joystick) is formulated. The function of the joystick traditionally assigned to the control of ailerons is replaced by that traditionally associated with the rudder pedals. Its function is otherwise conventional. From this topology it follows that small and continuous adjustments of the controls should cause the stabiliser to rotate in a direction opposite to that of the joystick (when viewed from aft) and the deflectio...

  11. Investigations on aged Ti-stabilised stainless steels

    Ehrnsten, U.; Karjalainen-Roikonen, P.; Nenonen, P. [VTT Industrial Systems, Espoo (Finland); Korhonen, R. [Fortum Nuclear Services, Vantaa (Finland); Timofeev, B.T.; Bloomin, A.A. [ZNIIKM, St. Petersburg (Russian Federation)


    Mechanical and microstructural properties of cast material of type O8X8H10TL and wrought and welded stainless steel pipe material of type O8X8H10T have been determined, aged at NPP operation temperature for about 100 000 h and 200 000 h, respectively. The mechanical properties were determined using tensile testing, impact energy determination and fracture resistance testing. The microstructures were studied using optical, scanning and transmission electron microscopy. The mechanical properties of the cast Ti-stabilised stainless steel material are evaluated to be only slightly affected by long term ({approx} 100 000 hours) operation at NPP operation temperature. Also the effect of even longer ({approx} 200 000 hours) operation on wrought Ti-stabilised pipe material is very small, as the properties of the aged material are within the normal range of as-manufactured material. The mechanical properties of the Mo-alloyed stainless steel weld metal after {approx} 200 000 hours of operation are still good, although indications of changes due to thermal ageing were observed.

  12. Stabilising emulsion-based colloidal structures with mixed food ingredients.

    Dickinson, Eric


    The physical scientist views food as a complex form of soft matter. The complexity has its origin in the numerous ingredients that are typically mixed together and the subtle variations in microstructure and texture induced by thermal and mechanical processing. The colloid science approach to food product formulation is based on the assumption that the major product attributes such as appearance, rheology and physical stability are determined by the spatial distribution and interactions of a small number of generic structural entities (biopolymers, particles, droplets, bubbles, crystals) organised in various kinds of structural arrangements (layers, complexes, aggregates, networks). This review describes some recent advances in this field with reference to three discrete classes of dispersed systems: particle-stabilised emulsions, emulsion gels and aerated emulsions. Particular attention is directed towards explaining the crucial role of the macromolecular ingredients (proteins and polysaccharides) in controlling the formation and stabilisation of the colloidal structures. The ultimate objective of this research is to provide the basic physicochemical insight required for the reliable manufacture of novel structured foods with an appealing taste and texture, whilst incorporating a more healthy set of ingredients than those found in many existing traditional products.

  13. The influence of the crop rotation, the nutrition regime and the herbicides on production and several productivity elements in winter wheat (Triticum aestivum L. cultivated on acid soils in the Western Plain of Romania

    Ileana ARDELEAN


    Full Text Available The crop rotation plant is a decisive factor influencing the growth and development of wheat .The choice of an appropriate crop rotation of plants, for instance, maintains a normal C/N ratio of 40-70 (assimilative C versus assimilative N. Bacterial N fixation in the soil and a normal C/N ratio are conditions that offer the forerunner plant ameliorative properties [11].The influence of plant cultivation technologies is expressed in the yield obtained per ha. The economic efficiency is quantifiedby the cost per ha or product unit.At present, this quantification is irrelevant due to the fact that products’ prices oscillate dramatically as a consequence of the inflation which is a characterisic of the present period. Thus, the most recommended method is to express the efficiency of the applied agrotechnical measures throught a different indicator, more stable and synthetic: KWh. This indicator is more realistic in respect to the investments and benefits of a cultivated crop and also makes possible the application of adequate measures leading to production increase per surface unit [1].

  14. Instrumentalizing Szeklerland Autonomy Through Szekler Memory Sites and Rites in post-1989 Romania

    Petru Szedlacsek


    Full Text Available In post-communist Romania, Szekler political and intellectual elites have taken advantage of a long discursive tradition on Szekler autonomy, which developed throughout the nineteenth and twentieth centuries within the nationalizing states (Brubaker 1996 of Hungary and Romania. As part of the interwar ideology of Transylvanianism, a particular Szekler identity-construction mechanism was developed, buttressed by a rhetoric on geographical remoteness in relation to the centers of power of Budapest and Bucharest. More precisely, the Szekler-ization of geography was enabled by imagining and cultivating sites and rites of memory in the Szeklerland – from pilgrimages to the funerary monuments of Szekler cultural elites and the sanctifying of Hungarian and Szekler flags in public squares. Drawing on this context, my paper explores the post-1989 revival of Szekler commemoration narratives that have attempted to construct a Szekler life-world within Romania by linking memory to territory. Since minority rituals of memory, parallel to the official state ones, are no longer silenced in Szekler public spaces after the fall of communism, interwar realms of memory have been reframed and popularized. On the line suggested by Katherine Verdery in The Political Lives of Dead Bodies (1999, this analysis also looks at how funeral ceremonies shape the relationship between the Szekler community and “its” territory with the Romanian Other. In this respect, this study focuses on the attempt to rebury the Szekler pro-Nazi writer József Nyirő on Szekler (yet Romanian soil. Apart from triggering a huge diplomatic incident between Hungary and Romania in the summer of 2012, it also pinpoints the reformulation of Szekler identity discourse within the Romanian post-communist context. In short, I will address questions regarding the practices of memory production permitted in present, the aims of Szekler elites in popularizing such practices and the way  these aims

  17. In-situ assessment of metal contamination via portable X-ray fluorescence spectroscopy: Zlatna, Romania.

    Weindorf, David C; Paulette, Laura; Man, Titus


    Zlatna, Romania is the site of longtime mining/smelting operations which have resulted in widespread metal pollution of the entire area. Previous studies have documented the contamination using traditional methods involving soil sample collection, digestion, and quantification via inductively coupled plasma atomic emission spectroscopy or atomic absorption. However, field portable X-ray fluorescence spectroscopy (PXRF) can accurately quantify contamination in-situ, in seconds. A PXRF spectrometer was used to scan 69 soil samples in Zlatna across multiple land use types. Each site was georeferenced with data inputted into a geographic information system for high resolution spatial interpolations. These models were laid over contemporary aerial imagery to evaluate the extent of pollution on an individual elemental basis. Pb, As, Co, Cu, and Cd exceeded governmental action limits in >50% of the sites scanned. The use of georeferenced PXRF data offers a powerful new tool for in-situ assessment of contaminated soils.

  18. Strength and Stiffness Development in Soft Soils: A FESEM aided Soil Microstructure Viewpoint

    Wijeyesekera, D. C.; Ho, M. H.; Bai, X.; Bakar, I.


    This paper opens with an overview of the debatable definition of soft soil that goes beyond a (CH) organic / inorganic clay and OH peat to include weakly cemented periglacial deposits of loess and alike. It then outlines the findings obtained from stiffness test on cement-stabilised soft clay. The findings are complemented with a microstructure viewpoint obtained using field emission scanning electron microscope (FESEM). Research also comprised of making cylindrical stabilised clay samples, prepared in the laboratory with various rubber chips contents and cement, and then aged for 28 days. The samples were then subjected to unconfined compressive strength (UCS) test and observations were also made of its microstructure using the FESEM. The impact of the soil microstructure on the stiffness result was studied both with the stabilized soil and also of some of the natural undisturbed loess soils. Sustainability aspect and the potential of the use of rubber chips and sand as additives to cement stabilisation are also discussed. The overall test results indicated that rubber chips and sand contributed to the improvement in unconfined compressive strength (qu). The derogatory influence of moisture on the stiffness of the stabilised clay was studied simultaneously. SEM micrographs are presented that show bonding of cement, rubber chips/ sand and soft clay, granular units and aggregated / agglomerated units in loess. The paper concludes with observations on the dependence of soil microstructure on the soil strength and deformability and even collapsibility of the loess. Current practices adopted as engineering solutions to these challenging soils are outlined.

  19. Quantifying lingual coarticulation using ultrasound imaging data collected with and without head stabilisation.

    Zharkova, Natalia; Gibbon, Fiona E; Hardcastle, William J


    Previous studies reporting the use of ultrasound tongue imaging with clinical populations have generally provided qualitative information on tongue movement. Meaningful quantitative measures for use in the clinic typically require the speaker's head to be stabilised in relation to a transducer, which may be uncomfortable, and unsuitable for young children. The objective of this study was to explore the applicability of quantitative measurements of stabilisation-free tongue movement data, by comparing ultrasound data collected from 10 adolescents, with and without head stabilisation. Several measures of tongue shape were used to quantify coarticulatory influence from two contrasting vowels on four different consonants. Only one of the measures was completely unaffected by the stabilisation condition for all the consonants. The study also reported cross-consonant differences in vowel-related coarticulatory effects. The implications of the findings for the theory of coarticulation and for potential applications of stabilisation-free tongue curve measurements in clinical studies are discussed.

  4. Study of Trajectory of Spin-Stabilised Artillery Projectiles

    M. Krishnamurthy


    Full Text Available Equations of motion for conventional spin-stabilised artillery projectile have been derived using a pseudo-stability axes system in addition to body-fixed and space-fixed axes systems. The aerodynamic forces and moments have been represented by their respective coefficients and the effects of Mach number and Reynolds number have been suitably accounted. The magnus terms which are significant at high rates of spin are estimated using a simple model. The set of equations have been partly linearised and solved numerically for a typical projectile using NAG system routines. Various trajectory parameters are computed and compared with the range-table data for the projectile. A parametric study had been carried out varying the aerodynamic coefficients to understand the sensitivity of the results obtained.

  5. Chinese Macroeconomic Stabilisation and Reform: A Briefing Note



    While reform of the Chinese public and external sectors has promoted growth, it has also led to increasing macroeconomic volatility. Such volatility has largely been due to China's de facto administrative and fiscal decentralisation and its de jure attempts at reasserting central control through fiscal and commercial regulation. Section Ⅱ will discuss some reasons for China's rapid economic growth and discuss the macro-level influences which caused output and inflation instability in the period 1979-1996. Section Ⅲ will discuss the effects of public sector reform on output and prices. Section Ⅳ will explore trade reform's effects on output and prices. The conclusion will discuss implications for stabilisation -where “stabilisation” is taken to comprise economic policies aimed at reducing inflation while promoting long-term output growth.

  6. Pulsed laser excitation of phosphate stabilised silver nanoparticles

    Jyotirmayee Mohanty; Dipak K Palit; Laxminarayan V Shastri; Avinash V Sapre


    Laser flash photolysis studies were carried out on two types of silver nanoparticles prepared by -radiolysis of Ag+ solutions in the presence of polyphosphate as the stabiliser. Type I silver nanoparticles displayed a surface plasmon band at 390 nm. Type II silver nanoparticles showed a 390 nm surface plasmon band with a shoulder at 550 nm. On photoexcitation in the surface plasmon band region, using 35 picosecond laser pulses at 355 nm and 532 nm, the type II solutions showed transient bleaching and absorption signals in the 450-900 nm region, which did not decay appreciably up to 5 nanoseconds. These transient changes were found to get annealed in the interval where 5 ns < < 100 ns. Extended photolysis of the nanoparticle solutions with repetitive laser pulses resulted in a decrease in the values of the average particle size which were measured by employing the dynamic light scattering technique.

  7. Stabilising compensators for linear time-varying differential systems

    Oberst, Ulrich


    In this paper, we describe a constructive test to decide whether a given linear time-varying (LTV) differential system admits a stabilising compensator for the control tasks of tracking, disturbance rejection or model matching and construct and parametrise all of them if at least one exists. In analogy to the linear time-invariant (LTI) case, the ring of stable rational functions, noncommutative in the LTV situation, and the Kučera-Youla parametrisation play prominent parts in the theory. We transfer Blumthaler's thesis from the LTI to the LTV case and sharpen, complete and simplify the corresponding results in the book 'Linear Time-Varying Systems' by Bourlès and Marinescu.

    Full Text Available The main objective of this paper is to study the Romania’s monetary policy, in the period 1996-2013. The research starts with a theoretical review of the monetary policy, whose main purpose is influencing the broad money supply and the lending requirements and the institution in charge of achieving this objective is the Central Bank, highlighting its impact upon the economic activity, through the Keynesian analysis model IS-LM and a correlation between the monetary policy measures and the phases of the economic cycle whose results indicate that during the recession periods it is recommended to reduce interest rates in order to stimulate investments, by raising the money supply, and during the expansion period it is recommended to increase the interest rate in order to cut back the money supply. Starting from this premises, the research takes into account the study of the monetary policy measures adopted by the governmental authority of Romania, making a quantitative analysis of the main macroeconomic indicators: the real interest rate, the lending interest rate, the deposit interest rate and the broad money supply and through a multifactorial regression, highlighting the impact of the interest rates upon the monetary aggregate M2. Moreover, a comparison between the monetary policy measures adopted in Romania and the monetary policies recommended by specialized literature has been done, and the results have indicated that during recession periods the attention of the governmental authorities is focused upon adopting the right measures, but during the expansion periods this doesn’t happen. The results of this research highlight the economic situation in Romania and the way in which the governmental authority intervened, through the monetary policy measures, in order to mitigate the negative effects of the cyclical fluctuations.

    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).

  2. Stabilisation of MSWI bottom ash with sulphide-rich anaerobic effluent.

    Sivula, Leena; Väisänen, Ari; Rintala, Jukka


    Effluent of an anaerobic sulphate-reducing wastewater treatment process was used to stabilise bottom ash. The effect of stabilisation on the concentration and binding of Ca, P, S, Cu, Pb, Zn, As, Cr, and Mo were studied by comparing results of sequential extraction from fresh and stabilised bottom ash. The stabilisation treatment improved the retention of Ca, Cu, Pb, S, and Zn in bottom ash compared to a treatment with ion-exchanged water. In addition to retention, Cu, S, and Zn were accumulated from the anaerobic effluent in the bottom ash. Concentrations of As, Cr, and Mo remained on the same level, whereas leaching of P increased compared to control treatment with ion-exchanged water. Improved retention and accumulation were the result of increased binding to less soluble fractions. The highest increases were in the sulphide and organic carbon bound fraction and in the carbonate fraction. Enhanced carbonation was probably due to CO2 deriving from the degradation of organic carbon. Flushing of stabilised bottom ash with ion-exchanged water ensured that the observed changes were not easily reversed. Most of the sulphide in the anaerobic effluent was removed when it was passed through bottom ash. The objective was to study the feasibility of sulphide-rich anaerobic effluent in bottom ash stabilisation and changes in the binding of the elements during stabilisation. In addition, the ability of the process to remove sulphide from the effluent was observed.

  3. An Updated Probabilistic Seismic Hazard Assessment for Romania and Comparison with the Approach and Outcomes of the SHARE Project

    Pavel, Florin; Vacareanu, Radu; Douglas, John; Radulian, Mircea; Cioflan, Carmen; Barbat, Alex


    The probabilistic seismic hazard analysis for Romania is revisited within the framework of the BIGSEES national research project ( 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.

  4. Impact of shifts in agriculture practices on lake ecosystems from SE Romania

    Iurian, Andra-Rada; Csaba Begy, Robert; Szabolcs, Kelemen; Simon, Hedvig; Martonos, Ildiko Melinda; Mircea Margineanu, Romul


    Well preserved lacustrine and wetland areas of special ecological interest from Ialomitei and Danube River Basins were investigated with the aim to assess temporal and spatial variability in sediment accumulation rates in relation to the multiple socio-economic and political changes that occurred with the rise and fall of socialism (1948-1989) in Romania. These shifts in the political systems resulted in space dynamics of the main land use/cover classes and their quality, a new type of landed property and land exploitation. The temporal context for the study (last 100 years) was provided by Pb-210 geochronology with Chernobyl Cs-137 as independent chronological marker. The study sites are located on the Southern Romanian Plain (Danube Plain), the main agricultural area in Romania, well known for high productivity of soils and good crop yields. The post-communist land reform resulted in the excessive fragmentation of farm land and the marked degradation of soil quality, leading to increased land vulnerability to extreme weathering and eventually to its abandonment in low-productive regions. The results are discussed in the context of the chronological data, sediment composition and historic meteorological records.

    Kiselev, Yurii M [Department of Chemistry, M.V. Lomonosov Moscow State University, Moscow (Russian Federation)


    The state-of-the-art in matrix stabilisation of d- and f-transition metal ions in unstable oxidation states is analysed. Main aspects of this problem concerning the genealogy of appropriate matrix systems are classified. Relevant examples are given and the data that contradict the scheme proposed are discussed. The thermodynamics of the matrix stabilisation effect is considered using the concept of isomorphic miscibility. The influence of defects and non-equilibrium on the matrix stabilisation effect is discussed. The problem of identification of the oxidation states in matrix systems is examined and various types of matrix systems are considered.

  6. State-feedback stabilisation for stochastic non-holonomic mobile robots with uncertain visual servoing parameters

    Zhang, Dongkai; Wang, Chaoli; Wei, Guoliang; Zhang, Hengjun; Chen, Hua


    The stabilising problem of stochastic non-holonomic mobile robots with uncertain parameters based on visual servoing is addressed in this paper. The model of non-holonomic mobile robots based on visual servoing is extended to the stochastic case, where their forward velocity and angular velocity are both subject to some stochastic disturbances. Based on backstepping technique, state-feedback stabilising controllers are designed for stochastic non-holonomic mobile robots. A switching control strategy for the original system is presented. The proposed controllers guarantee that the closed-loop system is asymptotically stabilised at the zero equilibrium point in probability.

  8. Romania needs a strategy for thermal energy

    Leca Aureliu


    Full Text Available The energy sector in Romania consists of three sub-sectors: electricity, natural gas and heat. Among these, the sub-sector of thermal energy is in the most precarious situation because it has been neglected for a long time. This sub-sector is particularly important both due to the amount of final heat consumption (of over 50% of final energy consumption, and to the fact that it has a direct negative effect on the population, industry and services. This paper presents the main directions for developing a modern strategy of the thermal energy sub-sector, which would fit into Romania’s Energy Strategy that is still in preparation This is based on the author’s 50 years of experience in this field that includes knowledge about the processes and the equipment of thermal energy, expertise in the management and restructuring of energy companies and also knowledge of the specific legislation. It is therefore recommended, following the European regulations and practices, the promotion and upgrading of district heating systems using efficient cogeneration, using trigeneration in Romania, modernizing buildings in terms of energy use, using of renewable energy sources for heating, especially biomass, and modernizing the energy consumption of rural settlements.

    Full Text Available The economic crisis, austerity measures and the new challenges of the 21st century have determined governments to adopt new tools of public actions in order to strengthen the policy capacity. A new paradigm was born, and its main feature is collaboration among government’s level (ministries and between government and private sector. It brings new tools of public policy among others, and contracting out used by policymakers at various stages of public policy cycle and for different sets of reasons. This paper explores theoretically how this new approach strengthens the public policy capacity and provides evidence occurring in Romanian government practice. While, Romania has a legalistic, a normative approach of policy processes and street-level bureaucracies are guided by managerial targets and law, it starts to contract out some tasks that traditionally belong to government. The main scientific objective of this paper is to contribute an overall understanding of contracting out in public policy-making in Romania, particular in pensions system, focused on the rationality of introducing that.From a methodological standpoint, the paper relies on comprehensive and systematic search of the literature and document analysis (among others Annual Reports, authorities’ data, resume, obtained by using free accession to information and statistics data processing (quantitative and qualitative interpretation of data from National Institute of Statistics.




    Full Text Available Evolution of structural changes in Romanian trade is somewhat interesting if you look at it from the perspective of mutations that occurred in the categories of goods and services subject to international trade. After the Revolution of 1989, the Romanian economy has gone through dramatic changes that had determinate a total reconfiguration of foreign trade. At the same time, the economic instability has had further repercussions on the Romanian economy manifested through higher prices, reduced wages or earnings, reduced employment and rising unemployment, increasing interest rates on loans due to the devaluation of the national currency, increase value-added tax, consumption reduction etc. We proposed in this paper an analyze for a significant period of time evolution of international trade in goods and services of Romania in order to establish the main categories of goods traded but Romania's main trading partners, too. In order to achieve the central goal of this paper we will use statistical data found in the databases provided by the WTO, Eurostat and the National Statistical Institutes and statistical methods to support our initiative.




    Full Text Available Throughout history, international relationships have always witnessed the forming of alliances, bilateral agreements, mutual treaties, conventions, partnerships or founding organizations. All these agreements have lasted as long as all the actors involved have shared a common interest, but during conflictual periods they have been reduced to simple sheets of paper. Certainly, the very same states have, again and again, been both ‘friends’ and ‘enemies’ because in international relations “nations have no permanent friends or allies, they only have permanent interests.”1 Thus, in a world of growing interdependence and continuous change, globalization will not turn this world into a flat one, nor will it bring history to an end. On the contrary, it will generate new threats and will make differences more obvious and more striking. Moreover, the events that have taken place during the last few years clearly point this out. Starting with the 2013 Summit in Vilnius, the European Neighbourhood Policy and the Eastern Partnership, in particular, have brought about major direct changes in Eastern Europe and indirect ones in Bruxelles, culminating in territorial changes in the immediate proximity of Romania. Taking into account both its significant geopolitical and geostrategic location and its membership to the European Union, Romania finds itself, as always, at a crossroads. In this context, the present paper aims at determining the role the European Union plays in Romania’s relationship with Russia.




    Full Text Available Economic disparities are disparities between levels of economicdevelopment of the areas or regions within a national economy. If economic literature hasfailed to explain the causes of inequalities in economic development of different regions of theEU, this issue became a priority in EU economic policy, especially after the adhesion ofGreece, Spain and Portugal, countries characterized by a lower level of development fromother EU countries and also marked by significant regional imbalances. European Unionsupports reducing disparities between different regions of Member States so that all regionsand their people to benefit from economic and social advantages of the Union. This paper aimsto highlight disparities between the macro-regions in Romania. Regional demarcation criterionin the NUTS system is the population’s number within a territory. Most pertinent argument isthat the goal of all activities in a society lies in meeting the needs of the individual and of thecommunity. This possibility is ensured by a certain level of economic development in the region.Less developed areas of Romania are located in Northern Moldova and in the South EasternRomanian Plain and the more developed areas include, in addition to Bucharest andConstanta, Transylvania and Banat regions.

    Full Text Available The organic market has been increasing in the past couple of years and it is still expected to do so. However, even though the prices are higher on the organic market, farmers do not always manage to benefit from these better prices. Romania is a country with a high potential for organic agriculture as there are 14.8 million hectares of agricultural land out of which arable land represents 8.9 million ha. According to NIS (2012a p. 89, in 2011, 29.2% of the country’s population was employed in agriculture. However, most households in rural areas produce for mere survival due mainly to the highly fragmented land owning. Therefore there is an acute need for new development strategies in order to improve living standards in rural areas. This article describes business models of organic cooperatives in Nepal and Romania. Moreover it proposes a rural development initiative based on the creation of organic cooperatives and suggests thata NGOs could implement such a program.

  16. Does Emigration Affects Wages? A Case Study on Romania

    Costin-Alexandru Ciupureanu


    Full Text Available The migration phenomenon in Romania is characterized by emigration; the number of Romanian migrants skyrocketed after the Romanian accession to the European Union in 2007. With the economic and financial crisis outlook and with the labour market liberalization across the whole European Union for the Romanian workers starting this year the number of Romanian migrants is expected to increase further. Against this background this paper analyses the effects of emigration on wages in Romania. It is found that emigration has a positive impact on wages in Romania.

  17. Bio agricultural product market in Romania and Europe

    Simona BĂLĂŞESCU


    Full Text Available The general objectives of this paper are to obtain an overview of the present market for organic agricultural products in Europe in general, and in Romania in particular. Organic agricultural production represents a small part of Romanian agricultural production and the development potential of organic agricultural production Romania is infinitely greater than what is done today. European consumers know little about the Romanian bio agriculture and even less about the huge potential of this sector. Organic food market is growing both in Europe and in Romania due to the increased interest of consumers to live healthier and improve the quality of life.




    Full Text Available In this paper we present the non-cash payment methods used in Romania against other European Union countries to stress the main differences of the latest developments in this specific area since the crisis errupted up to present. In Romania, the most common payment method is transfer credit, because of its simplicity and because it is less risky than the other non-cash payment methods, while in EU direct debit and credit cards are more common. However, the value per transaction for any type of non-cash instruments (except for cheques is smaller in Romania than in other EU countries.

  20. Mean square stabilisation of complex oscillatory regimes in nonlinear stochastic systems

    Bashkirtseva, Irina; Ryashko, Lev


    A problem of stabilisation of the randomly forced periodic and quasiperiodic modes for nonlinear dynamic systems is considered. For this problem solution, we propose a new theoretical approach to consider these modes as invariant manifolds of the stochastic differential equations with control. The aim of the control is to provide the exponential mean square (EMS) stability for these manifolds. A general method of the stabilisation based on the algebraic criterion of the EMS-stability is elaborated. A constructive technique for the design of the feedback regulators stabilising various types of oscillatory regimes is proposed. A detailed parametric analysis of the problem of the stabilisation for stochastically forced periodic and quasiperiodic modes is given. An illustrative example of stochastic Hopf system is included to demonstrate the effectiveness of the proposed technique.

  1. On Fluxed Instantons and Moduli Stabilisation in IIB Orientifolds and F-theory

    Grimm, Thomas W; Palti, Eran; Weigand, Timo


    We study the superpotential induced by Euclidean D3-brane instantons carrying instanton flux, with special emphasis on its significance for the stabilisation of Kahler moduli and Neveu-Schwarz axions in Type IIB orientifolds. Quite generally, once a chiral observable sector is included in the compactification, arising on intersecting D7-branes with world-volume flux, resulting charged instanton zero modes prevent a class of instantons from participating in moduli stabilisation. We show that instanton flux on Euclidean D3-branes can remove these extra zero modes and helps in reinstating full moduli stabilisation within a geometric regime. We comment also on the F-theoretic description of this effect of alleviating the general tension between moduli stabilisation and chirality. In addition we propose an alternative solution to this problem based on dressing the instantons with charged matter fields which is unique to F-theory and cannot be realised in the weak coupling limit.

  5. Moduli stabilisation with nilpotent goldstino: vacuum structure and SUSY breaking

    Aparicio, Luis; Quevedo, Fernando; Valandro, Roberto


    We study the effective field theory of KKLT and LVS moduli stabilisation scenarios coupled to an anti-D3-brane at the tip of a warped throat. We describe the presence of the anti-brane in terms of a nilpotent goldstino superfield in a supersymmetric effective field theory. The introduction of this superfield produces a term that can lead to a de Sitter minimum. We fix the Kähler moduli dependence of the nilpotent field couplings by matching this term with the anti-D3-brane uplifting contribution. The main result of this paper is the computation, within this EFT, of the soft supersymmetry breaking terms in both KKLT and LVS for matter living on D3-brane (leaving the D7-brane analysis to an appendix). A handful of distinct phenomenological scenarios emerge that could have low energy implications, most of them having a split spectrum of soft masses. Some cosmological and phenomenological properties of these models are discussed. We also check that the attraction between the D3-brane and the anti-D3-brane does not affect the leading contribution to the soft masses and does not destabilise the system.

  8. Simultaneously stabilising controllers for time-varying linear systems within the framework of nest algebras

    Wang, Hongzhu; Yu, Tianqiu; Xiao, Jinmei


    From the perspective of strong transitivity, a controller design method is provided to simultaneously stabilise a collection of time-varying linear systems within the framework of nest algebras. In particular, all simultaneously stabilising controllers for a class of linear plants are characterised based on the doubly coprime factorisations. These results hold as well in the time-invariant case. An illustrative example is given to demonstrate the validity of the method.

  10. Global D-brane models with stabilised moduli and light axions

    Cicoli, Michele


    We review recent attempts to try to combine global issues of string compactifications, like moduli stabilisation, with local issues, like semi-realistic D-brane constructions. We list the main problems encountered, and outline a possible solution which allows globally consistent embeddings of chiral models. We also argue that this stabilisation mechanism leads to an axiverse. We finally illustrate our general claims in a concrete example where the Calabi-Yau manifold is explicitly described by toric geometry.

    Full Text Available The Szeklers and Hungarians from Romania. This study regards, as its main topic, the possibility of establishing at present, a geodemographical entity on Romania’s territory, since certain representatives of the Hungarian ethnical minority in our country, and with a particular insistence of those in the vicinity of the western border, always remember to bring into view the problem of establishing an autonomy, common to a Székely Land, located in the central area of our country, which would include Mureş, Harghita and Covasna counties. Without carrying out a detailed account of this situation, it needs to be mentioned, just as it will emerge of the following presentation, that such an approach has neither the most reduced geodemographical support, since the Szeklers, after being assimilated by the Hungarian ethnic group, are no longer present at the census of 20 October 2011. By taking into account the above mentioned aspects, in order to be able to respond to the insistent requests for autonomy in Transylvania, we proceeded to highlight, through a fairly detailed approach of the Hungarian ethnical minority, obviously in point of the number of inhabitants and of their distribution on Romania’s territory, resulting of this the fact that the number of Hungarians is of 1,227,623 people, value which related to those 20,121,641 inhabitants of Romania, means 6.10%.

    Iosip, A.


    Full Text Available The economic crisis has affected many areas but the auto industry is perhaps one of the most affected. Renault, Ford, General Motors, Toyota, Volkswagen, BMW are just some of the big players caught unprepared. Through this paper we propose an analysis of the automotive market in Romania in order to understand the sales decrease of the last two years. At the same time we aimed at understanding the reasons that led to a decrease in car sales, what were the measures taken by the government to stop this phenomenon and how the economic crisis influenced the automotive field in Romania. An objective image of the situation in the automobile market in Romania at this moment also requires an analysis of the marketing environment and the changes it has undergone over time. Last but not least we will try to find a series of measures to re-launch the car market in Romania.

  20. Priorities in Investment Decisions for Rural Development in Romania

    Ana Popa


    Full Text Available Romania joined the European Union- EU -in 2007, as an emerging economy and rural by excellence and this feature is keeping even in 2012. Difficulty in establishing investment priorities for rural development in Romania is caused by the large size and fragility of the rural area and the fact that all inputs have an inadequate level. The objectives of rural development are strongly influenced by national policy and European policy of the European Union, but also by the politics of international organizations (World Bank Group-WBG, Food and Agriculture Organization-FAO. Investment for climate changes and for infrastructure is strongly correlated and is vital in all states, including Romania. The six EU Priorities for rural development in the period 2014-2020 are also considering priorities for increasing education level and social inclusion in the rural areas, which are other pressing needs in Romania in order to move to a modern agriculture.

  4. Analysis Regarding the Growing Presence of Italian Firms in Romania

    Stefano Valdemarin


    Full Text Available At the end of 2014, the number of firms with an Italian presence in Romania was 39,556, representing 19.33% out of total registered firms and this number is still growing. This article focuses on answering the following question: what kind of Italian firms are investing in Romania and why? Starting from the empirical observation that the number of Italian firms in Romania grew by 6.82% last year, we have used a PESTEL analysis to find the key points characterizing the country, paying attention also to the concept of country brand. From the point of view of Italian firms, we have also analyzed the shifting paradigm of internationalization from a Vertical Foreign Direct Investment model to a Horizontal Foreign Direct Investment model.

    Full Text Available After nearly three years of intensive consultations, 2015 has been declared the International Year of Soils by the 68th UN General Assembly (A/RES/68/232. The International Years of Soil is to be a major platform for raising awareness of the importance of soils for food security and nutrition and essential eco-system functions. Key objectives of the International Years of Soil have been identified as follows: to create full awareness of all stakeholders about the fundamental roles of soils for human life; to achieve full recognition of the prominent contributions of soils to food security and nutrition, climate change adaptation and mitigation, essential ecosystem services, poverty alleviation and sustainable development; to promote effective policies and actions for the sustainable management and protection of soil resources; to sensitize decision-makers about the need for robust investment in sustainable soil management activities, to ensure healthy soils for different land users and population groups; to catalyze initiatives in connection with the Sustainable Development Goal process and Post-2015 agenda; to advocate rapid enhancement of capacities and systems for soil information collection and monitoring at all levels (global, regional and national ( Applying a proper management of the recovery and conservation of soil resources is a major goal for every nation. The development of a country depends on the production potential of own soil resources. Soil degradation is a serious problem in Europe an also in Romania. It is caused or exacerbated by human activity such as inadequate agricultural and forestry practices, industrial activities, tourism, urban and industrial expansion etc. Soil Quality Monitoring in Romania revealed a number of problems concerning land use in Romania following the manifestation of one or more limiting factors such as: moisture deficit, salinization and alkalization, soil erosion

  8. Geochemical and mineralogical characteristics of percolates and its evaporates from Technosols before and after limestone filler stabilisation.

    Pérez-Sirvent, Carmen; Martinez-Sanchez, Maria Jose; Garcia-Lorenzo, Maria Luz; Hernandez-Cordoba, Manuel


    The chemistry of waters is recognized as a relevant monitoring tool when assessing the adverse effects of acid mine drainage. The weathering of sulphide minerals produces a great variety of efflorescences of soluble sulphate salts. These minerals play an important role for environmental pollution, since they can be either a sink or a source for acidity and trace elements. This communication deals with the leachability of potentially toxic elements (PTE) eluting from technosols formed from soils affected by mining activities and limestone filler. A total of three contaminated soils affected by opencast mining were selected and mixed with limestone filler at three percentages: 10 %, 20 % and 30 %, providing nine stabilised samples. These samples were stored in containers and moistened simulating rainfall. The percolates obtained were collected, and the PTEs content (As, Cd, Cu, Fe, Pb and Zn) was determined. Evaporation-precipitation experiments were carried out in these waters, and the mineralogical composition of efflorescences was evaluated. The study area is heavily polluted as a result of historical mining and processing activities, producing large amount of wastes, characterised by high trace elements content and acidic pH. The results obtained for the percolates after the rain episode showed that, before the stabilization approach, waters had an acidic pH, high electrical conductivity and high PTEs content. When these soils were mixed with 10, 20 and 30 % of limestone filler, the pH was neutral and the soluble trace element content strongly decreased, being under the detection limit when limestone percentage was 20 % and 30 %. The mineralogical composition of efflorescences before the stabilisation approach showed that predominant minerals were copiapite, followed by gypsum and bilinite. Other soluble sulphates were determined in lower percentage, such as hexahydrite, halotriquite or pickeringite. After the mixing with 10 % of limestone filler, the evaporates

  9. Knowledge Economy and its Effects in Romania

    Prof. Ph. D. Laura Cismas


    Full Text Available Knowledge economy implies that the rationality of individuals is limited because they make and adapt their choices in an environment affected by risk and uncertainty. The first part of this paper proposes an analysis of the knowledge economy, based on its interdisciplinary nature. Thus, classical theories adapt to visions that pertain to the dynamics of human interactions, the restructuring of the social network theory, the general equilibrium theory and the game theory.The research part of this paper identifies and explains the link between innovation and knowledge, as well as its effects on the Romanian economy’s competitiveness and innovation. The conclusions illustrate that the consolidation of knowledge-based economy in Romania implies setting certain priorities, such as: investing in education, developing entrepreneurship, creating an innovative and efficient system made up of companies, research centers and universities, which enables new technologies to be absorbed, adapted and created for the society.

  10. Regional Specialisation and Economic Concentration in Romania

    Neagu Olimpia


    Full Text Available The purpose of the paper is to give an overview of the changes in the structure of industries in Romania, specifically on the questions (1 whether the industrial structures become more similar or more different in the Romanian regions and (2 whether the Romanian industries become more concentrated or more dispersed. EUROSTAT regional data on Gross Value Added and employed population for the period of 2000-2013 are used in order to calculate several statistical indices of specialization and concentration (Krugman, Entropy, Hirschman-Herfindahl, Lilien Index and Gini coefficient. By comparing the values of these different measurements, the main finding is that Romanian regions become less specialized, while industries become slightly more concentrated. The speed of structural changes in all Romanian regions registered a noticeable slowdown of the speed of sectoral changes after the economic crisis. Our conclusions provide useful information for the economic policy makers in investment funds allocation or employment measures designing.




    Full Text Available This article had as starting point the evolution of expenditures for environmental protection in Romania. Evolution of environmental expenditures recorded a general upward trend, with a decrease in 2009, which can be explained as a result of the economic crisis. The first step was to conduct an overall analysis. This was followed by an analysis by fields and by categories of producers. The processed data were taken from the National Institute of Statistics. An increase of these expenditures, both overall and by categories was observed from the analysis of trends. This increase suggests an improvement in the implementation of environmental objectives in order to ensure a harmonious and long-term transition to a green economy.

    Full Text Available This paper analyzes the evolution of rural tourism since the early '70s, the time of onset, and indicates the discontinuity recorded especially after 1989 until the brink of the preparation for Romania's joining the European Union and the present state, one far behind the countries with extremely high degree of urbanization and industrialization, probably as a result of a lack of strategy for this form of tourism in which the beneficiary is the Ministry of Tourism, as the health tourism and ecotourism have recently had. The location of many villages in areas of outstanding natural landscapes, the richness and variety of cultural heritage that endows them, are issues related to an increased tourism potential that can be capitalized and those unique tourism products that can not be seen, admired and offered by other countries.

  19. Romania becomes a candidate for accession to CERN

    CERN Bulletin


    Romanian Minister Daniel Petru Funeriu, and CERN Director-General Rolf Heuer. On Thursday 11 February Romanian Minister of Education, Research, Youth and Sport, Daniel Petru Funeriu, and CERN Director-General, Rolf Heuer, signed an agreement that formally recognises Romania as a Candidate for Accession to membership of CERN. Romania’s pre-membership will cover a five-year period during which the country’s contributions will ramp up to normal Member State levels, in parallel with Romania's participation in CERN projects. At the end of this five-year period the Council will decide on Romania's application for full membership, as the Organization's 21st Member State. Romania entered into direct collaboration with CERN in the early 1990s.

Romania is involved in three LHC experiments, namely ATLAS, ALICE and LHCb . It al...

  20. Culture And Leadership: The Case Of Romania

    Raluca-Elena Hurduzeu


    Full Text Available Globalization and internationalization lead to the development of a general image of good and effective leadership which influence the local leadership styles and the behavior of leaders. The latter must overcome the conflict between the desire to implement corporate standards which are internationally valid and the need to act locally in terms of organizational culture, business environment and leadership style. The knowledge of the national peculiarities and traditions, the understanding of their heritage and background, coming to grips with them are key-success factors for international co-operations and/or joint-ventures in today’s competitive world. The aim of this paper is to explore the connection between the organizational culture and the leadership style and aims to develop a better understanding of the Romanian leadership. It also provides important information and ideas on the leadership styles practiced in the companies within Romania. The study presents the research findings on the Romanian leadership style and connects it to the political, economic and cultural influences. As far as Romania is concerned, although the variations in the cultural configurations are of a great diversity and complexity, we may, however, identify two distinct types of organizational culture, supporting the hypothesis that these two categories are the extremes of a continuum with a wide variety of expression: a culture of ‘bureaucratic’ type, typical for: state-owned companies, former state firms in the post-privatisation period and the culture of ‘entrepreneurial’ type, in the process of formation, typical for the private companies formed after 1989. The most important problems that appear in the case of the multinational companies refer to the compensation values, sacred and taboo, the management of the gradual conflicts, etnocentrism, affiliation, faulty conciliation and naive realism. The leaders must learn to analyze the cultural




    Full Text Available By all analyses, the remittances flows describe a trend of significant growth worldwide, over the past two decades, currently representing an extremely important component of capital for the poor and developing countries. Compared to other capital flows (foreign direct investment, development aid or other types of private capital, the remittances size is positioned, generally, only behind FDI, causing direct and indirect socio-economic effects, far more profound than other types of capital. Moreover, studies show that remittances flows tend to a much greater stability over time as compared to other balance of payments flows, especially the exports and the private capital. Romania is an important recipient economy. If in 2000, the value of the entries was 96 million USD, in 2008, the amounts remitted from abroad reached a peak of over 9.2 billion USD, after which, during the global economic crisis, they declined, reaching a value of 3.5 billion USD, in 2013. Over the years, along with FDI, the capital flows from remittances have significantly contributed to the economic growth and to the increase of the welfare of an important part of the population by improving economic and social status. However, how important have the remittances flows proved to be for the economy as a whole? Is there any influence of these amounts on the inflation, labour market, education, or entrepreneurship? How much is Romania losing by dispatching such an important part of its population to work abroad, and how much does it earn from the money remitted home?

  2. Microfluidic Fabrication of Hydrocortisone Nanocrystals Coated with Polymeric Stabilisers

    David F. Odetade


    Full Text Available Hydrocortisone (HC nanocrystals intended for parenteral administration of HC were produced by anti-solvent crystallisation within coaxial assemblies of pulled borosilicate glass capillaries using either co-current flow of aqueous and organic phases or counter-current flow focusing. The organic phase was composed of 7 mg/mL of HC in a 60:40 (v/v mixture of ethanol and water and the anti-solvent was milli-Q water. The microfluidic mixers were fabricated with an orifice diameter of the inner capillary ranging from 50 µm to 400 µm and operated at the aqueous to organic phase flow rate ratio ranging from 5 to 25. The size of the nanocrystals decreased with increasing aqueous to organic flow rate ratio. The counter-current flow microfluidic mixers provided smaller nanocrystals than the co-current flow devices under the same conditions and for the same geometry, due to smaller diameter of the organic phase stream in the mixing zone. The Z-average particle size of the drug nanocrystals increased from 210–280 nm to 320–400 nm after coating the nanocrystals with 0.2 wt % aqueous solution of hydroxypropyl methylcellulose (HPMC in a stirred vial. The differential scanning calorimetry (DSC and X-ray powder diffraction (XRPD analyses carried out on the dried nanocrystals stabilized with HPMC, polyvinyl pyrrolidone (PVP, and sodium lauryl sulfate (SLS were investigated and reported. The degree of crystallinity for the processed sample was lowest for the sample stabilised with HPMC and the highest for the raw HC powder.

    To compare the erosion protection efficacy of a stabilised, stannous fluoride (SnF2 ) dentifrice versus a sodium fluoride (NaF) dentifrice using a modified in situ clinical model. This study, a randomised parallel group in situ design with in vivo product use and ex vivo acid challenge, compared: A, a dentifrice containing 1,450 ppm F as NaF; B, a dentifrice containing 1,450 ppm F (1,100 ppm F as SnF2 + 350 ppm F as NaF); and T, tap water. Sample size was n = 4 per group (total of 12 subjects) and within each subject appliances were placed on each side of the mouth (left and right). Enamel specimens were placed in different positions of the mouth (front, mid-front, mid-rear, rear) in each appliance (total = 8 specimens per subject). Product treatment was twice per day (lingual brushing for 30 seconds followed by swishing for 90 seconds with the resultant product/saliva slurry) in vivo for 15 days, and ex vivo acid treatment (0.02 m citric acid 5 minutes four times per day; total exposure time = 300 minutes). Data were analysed using a general linear repeated measures model with treatment, side and position as fixed effects. Within subjects, correlations were modelled assuming a different correlation and variance for treatment B relative to the other groups. Pairwise treatment differences were performed using a 5% two-sided significance level. Enamel loss (in μm) was significantly lower (P dentifrice versus a conventional NaF dentifrice, validating the ability of the model to safely and effectively demonstrate differences in the erosion protection potential of oral care products. © 2014 FDI World Dental Federation.

  4. Wind power stabilising control. Demonstration on the Nordic grid

    Elkington, Katherine


    When unconventional types of generators such as doubly fed induction generators (DFIGs) are used in a power system, the system behaves differently under abnormal dynamic events. For example, DFIGs cause different modes of oscillation in the power system, and respond differently to changes in voltage. In order to damp oscillations in the system, it is necessary to understand the equipment causing these oscillations, and the methods of optimally damping the oscillations. Large power oscillations can occur in a power system as a result of disturbances. Ordinarily these oscillations are slow and, in principle, it is possible to damp them with the help of wind power. This suggests the use of a power oscillation damping (POD) controller for a DFIG, similar to a power system stabiliser (PSS) for a synchronous generator. Voltage stability is another important aspect of the safe operation of a power system. It has been shown that the voltage stability of a power system is affected by induction generators and also DFIGs, and we investigate some aspects of this here. In this study we develop control strategies for large wind farms comprising DFIGs, and study the impact of the wind farms on a system which is designed to reflect the dynamics of the Nordic power system. The design of multiple PODs in a wind farm is undertaken using linear matrix inequalities (LMIs). The impact of the wind turbines is investigated through the use of linear and dynamic simulations. It has been demonstrated that DFIG-based wind farms can be used for damping oscillations, even when they are not producing their rated power, and that they can also improve the critical clearing time of some faults. However, they may have an adverse impact on power systems after large voltage disturbances

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

    Niacsu, Lilian; Ionita, Ion


    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.

  6. Mine waste management legislation. Gold mining areas in Romania

    Maftei, Raluca-Mihaela; Filipciuc, Constantina; Tudor, Elena


    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

  7. The importance of ecosystem services for rural inhabitants in a changing cultural landscape in Romania

    Tibor Hartel


    Full Text Available Many traditional cultural landscapes evolved as coupled social-ecological systems. It is important to understand how such systems navigate novel challenges posed by globalization. To address this issue, we bring together two components of a pilot study carried out in a cultural landscape from Central Romania. The region was affected by major social and economic perturbations in the past century, affecting ethnic composition, community cohesion, land property regimes, and the management of common resources. The first component of our study investigated how rural inhabitants appreciated ecosystem services through questionnaires with 98 people in 30 villages. The second component aimed to assess the perception of people about ongoing changes in their communities through semistructured interviews with 50 people in 5 villages. Rural inhabitants particularly valued provisioning ecosystem services such as firewood, water, and crops, but also healthy soils. Rural communities were characterized by a number of social and economic issues, especially individualism, lack of trust, corruption, and poverty. People from communities with many initiatives, e.g., NGOs, associations, and active individuals, were more optimistic regarding the future of their communities than people from villages with few or no initiatives. A major challenge for cultural landscapes such as those in Central Romania is to find new, meaningful ways to keep the social and ecological systems connected. Otherwise there is a risk that (short-term socioeconomic interests may impair the provisioning of important ecosystem services.

He had an entire team and an institutional system that worked for making anti-Semitism a state policy and practice. The beginning of WW II from the East meant for the Jews the acceleration of the destructive phase of their destiny. During the meeting of the Council of Ministers of September 6, 1941, Ion Antonescu stated the purpose of the war against the USSR and the drastic measures against the Jewish population.

  9. Global stabilisation for a class of uncertain nonlinear time-delay systems by dynamic state and output feedback

    Chai, Lin; Qian, Chunjiang


    This paper investigates the design problem of constructing the state and output feedback stabilisation controller for a class of uncertain nonlinear systems subject to time-delay. First, a dynamic linear state feedback control law with an adaptive strategy is developed to globally stabilise the uncertain nonlinear time-delay system under a lower-triangular higher-order growth condition. Then, one more challenging problem of the adaptive output feedback stabilisation is addressed, which can globally stabilise the time-delay system when the unmeasurable states linearly grow with rate functions consisting of higher-order output.

  10. Vulnerability of housing buildings in Bucharest, Romania

    Bostenaru, M.


    The author participates to the World Housing Encyclopedia project (, 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

  12. Stabilisation of health as the centre point of a health psychology of ageing.

    Scholz, Urte; König, Claudia; Eicher, Stefanie; Martin, Mike


    Current health psychological theories and research mainly cover improvement of health, recovery from illness or maintenance of health. With this theoretical manuscript, we argue that in ageing societies in which chronic illness and multimorbidity become the norm rather than the exception, this focus of health psychology is no longer sufficient. Instead, in line with a recent conceptualisation of health as "the ability to adapt and to self-manage", we suggest that the centre point of a health psychology of ageing needs to be the stabilisation of health. Current theories of lifespan development, such as the model of selection, optimisation and compensation, the motivational theory of life span development, the two-process model of assimilative and accommodative coping and the recently introduced functional quality of life model are described with regard to their assumptions and related research focussing on stabilisation. All of these models explicitly comprise stabilisation as an important process of successful, healthy ageing. So far, however, the empirical research examining these models does not take stabilisation into account. Implications for research methods and practise of health stabilisation are discussed.

  13. SDP-based approximation of stabilising solutions for periodic matrix Riccati differential equations

    Gusev, Sergei V.; Shiriaev, Anton S.; Freidovich, Leonid B.


    Numerically finding stabilising feedback control laws for linear systems of periodic differential equations is a nontrivial task with no known reliable solutions. The most successful method requires solving matrix differential Riccati equations with periodic coefficients. All previously proposed techniques for solving such equations involve numerical integration of unstable differential equations and consequently fail whenever the period is too large or the coefficients vary too much. Here, a new method for numerical computation of stabilising solutions for matrix differential Riccati equations with periodic coefficients is proposed. Our approach does not involve numerical solution of any differential equations. The approximation for a stabilising solution is found in the form of a trigonometric polynomial, matrix coefficients of which are found solving a specially constructed finite-dimensional semidefinite programming (SDP) problem. This problem is obtained using maximality property of the stabilising solution of the Riccati equation for the associated Riccati inequality and sampling technique. Our previously published numerical comparisons with other methods shows that for a class of problems only this technique provides a working solution. Asymptotic convergence of the computed approximations to the stabilising solution is proved below under the assumption that certain combinations of the key parameters are sufficiently large. Although the rate of convergence is not analysed, it appeared to be exponential in our numerical studies.

Complications of these techniques include cutout or back out of the screws and plates, avascular necrosis, nonunion, malunion, nail migration, rotator cuff impairment and impingement syndromes. Insufficient anchorage from conventional implants may lead to early loosening and failure, especially in osteoporotic bones. In general, nonoperative treatment of displaced three and four-part fractures of the proximal humerus leads to poor outcome due to intraarticular nature of injury and inherent instability of the fragments. Comminuted fractures of the proximal humerus are at risk of fixation failure, screw loosening and fracture displacement. Open reduction and internal fixation with conventional plate and screws has been associated with unacceptably high incidence of screw pull out. PHILOS (the proximal humeral internal locking system plate is an internal fixation system that enables angled stabilisation with multiple interlocking screws for fractures of the proximal humerus. MATERIALS AND METHODS 30 patients with proximal humerus fractures who were admitted in the Department of Orthopaedics, Government General Hospital, Kakinada, during the period November 2014 - November 2016 were taken up for study according to inclusion criteria. All patients were treated with PHILOS plate. These proximal humerus fractures were classified according to Neer’s classification. Patients were followed up at 6 weeks, 12 weeks and 6 months’ interval. Functional outcomes for pain, range of motion and muscle power and function were assessed using the Constant-Murley scoring system. Collected data analysed with independent t-test and ANNOVA test. RESULTS The outcome of the study was 1

    Corina-Liana MANIU


    Full Text Available Objectives: A comparative research regarding the occurrence and evolution patterns of the HIV-AIDS epidemic between Romania and the major areas (Sub-Saharan Africa (SSA and the USA, respectively in order to establish the current trends of the diseases and the specific prognosis. Material and Methods: The research represents a systematic study over the entire period, of the HIV-AIDS pandemic from 1981-2008, based on specialty literature published in English or Romanian. In addition to theses, published articles, materials presented at conferences and congresses, reports and information from the main governmental and international organizations such as WHO, CDC, UNAIDS have been consulted. Results: Romania was the first country in Central and Eastern Europe to announce the diagnosis of an AIDS case in 1985. Since then, the prevalence per 100000 population of HIV infection cases, has demonstrated an ascending trend from 0.27 in 1992 to 19.67 in 2007. HIV-AIDS infection in children from Romania is unique worldwide. Therefore, from the cumulative total of 7606 AIDS pediatric cases between 1989-2007, 4885 have had a nosocomial transmission. The mother-to-child transmission is well controlled in Romania, similar to the USA. High-risk groups (injecting drug users or men having sex with men, represent a small percentage among the Romanian HIV-AIDS and SSA cases, compared to the USA. Romania, similar to the rest of Europe and USA, has not experienced in general population.

  19. The Potential Sources of Change in Romania Regional Policy

    Gabriela Marchis


    Full Text Available There have been numerous debates on a new territorial organization of Romania during 2013 and 2014. The miracle of Romania regionalization was deemed to have contradictory effects from territorial construction to dissolution. Due to the presidential elections from the end of 2014, the process of regionalization was postponed, but some questions are still very alive: It is necessary to regroup counties into regions? The low development of Romania regions is caused by the lack of administrative decentralization? In Romania, territorial reform is synonym with institutional reform? Therefore, I consider that it is important to identify the potential sources of change in Romanian regional policy. The political debates on Romanian regionalization were mainly focus on political interests, without taking into account an important serious of factors that can spur growth and socio-economic development across our regions. Through this paper I try to investigate the specialised literature in order to identify some useful policy suggestions from regional scientists, which would be proper for Romania regional development, in the current context of Europe 2020 strategy.

    Full Text Available In this paper the authors analyze the migratory movement of population from Romania. Demographic dynamics of the last decade confirms that Romania's population declined. The demographic developments in Romania have mainly economic reasons (examples : migration, low birth rate, rural - urban migration. The comparative analysis of statistical data obtained in the population censuses of 2002 and 2011 shows that the most of the Romanian communities have lost population due to a negative natural and migratory growth. Fron the situation of the absent population ( migrants at the time of the population census, between 2002 and 2011 is that the number of those who have left home for longer periods has increased exponentially. Most of those absents from their home at the time of the last population census were living abroad. Romania needs a realistic vision of economic and social development in the coming decades. In defining and naming a strategy for sustainable development, population is the central element and from this perspective one of the strategy component should be to stop the demographic skidding. Simultaneously with the decrease of the total population, Romania records a demographic aging trend. The causes are both negative natural growth ( low birth rate combined with high mortality and also the migration phenomena. Projections show that these trends will persist on the medium and long term.

    Georgescu Cecilia


    Full Text Available The present communication contains research and experimental investigations regarding the labelling process of dairy products in tight relation with the national and European legislative requirements. Two methods have been used during the marketing research regarding the information present on the labels of alimentary products: the method based on documentation-observation and comparative analysis of data and information collected from the consume market in Sibiu. The method based on documentation and observation has been carried out using the observation sheet and contained the following analysis criteria: The name of the product, Country origin of the product (location of the producer. Synthesizing the results and the conclusions emerged as a result of the marketing research carried out with the purpose of contouring a labelling model of alimentary products, it can be stated that the dynamics of the alimentary products market in Romania is moderate and restrained by the economical and social factors and even by the still reduces promotion of a healthy alimentary education, with the complementary protection of human health and environment.

  2. Industry in growth poles of Romania

    Cristina Iacoboaea


    Full Text Available A competitive industry can reduce costs and prices, can create new products, thus contributing significantly to productivity growth throughout the economy. The industry is also the main source of innovation necessary for society to meet the challenges faced. Growth poles have the ability to spread economic development in adjacent areas and contributes significantly to the territorial development of the country. This article aims to analyze the current state of industry growth poles of Romania, in terms of number of employees, distribution of sub-industries and density of firms in industry. It also highlights business structures and industry clusters located in the growth poles, as solutions for boosting economic growth and creation of added value. Analysis performed leads to the conclusion that all growth poles are engines of economical development in the industry for the regios of origin. We distinguish growth poles Timişoara and Cluj-Napoca whose economic advantage is given by the favorable position close to the markets of the European Union.




    Full Text Available Construction, in the conception of several specialists, are a part of the tertiary sector and therefore are considered service activities. Lately we are witnessing a significant increase in services activities, be it civil or industrial construction, be it interior design or road construction. One of the most dynamic sectors of the Romanian economy is the construction industry, and we say this because we are witnessing in recent years to an increase of specialized companies number, entering the Romanian market of a large number of companies representing multinationals and major investments in projects scale. Another determining factor in the evolution of the construction market in Romania refers to increasing the comfort level required by the population, something that sets new construction, modification of existing investments in interior design of living spaces or industrial ones. We will try in this paper to support the idea that construction are service activities and present trends of development of this highly specific branches of the national economy. We will make a trip in time to determine the trend of development but also in space to have an overview of the level of construction development in various regions of the country. We will use in this sense the specialty literature and statistical data available at the moment.

  4. Research about Quality Life in Romania

    Constantin Mitrut


    Full Text Available he life quality research is in fact a major field of the analysis on the social and economic evolution of a country. The living standard (life quality keeps on being a quite sensitive issue as it implies a number of both methodological and or organizational aspects. The most frequently the life quality is studied on the basis of the surveys being organized at the households level.These surveys (investigations at random must be achieved in such a way that, by extending the data, they allow us to stick with the fore casted margin of error. This is specifically the reason for this material to briefly bring up the methodology which is applying when organizing a survey. Out of the immensity of data we have selected, after processing them, those conclusions which we considered as being the most significant for suggesting the life quality in Romania. The work includes tables and graphs, being abundantly thrown into relief by absolute and relative data.




    Full Text Available Internal control is indissolubly linked to business and accounting. Throughout history, domestic and international trade has grown exponentially, which has led to an increasing complexity of internal control, to new methods and techniques to control the business. The literature has presented the first models of internal control in the Sumerian period (3600 - 3200 BC, and the emergence and development of internal control in Egypt, Persia, Greek and Roman Empire, in the Middle Ages till modern times. The purpose of this article is to present the models of internal control in Romania, starting from the principles of the classical model of internal control (COSO model. For a better understanding of the implication of internal control in terms of public and private sector, I have structured the article in the following parts: (a the definition of internal control in the literature; (b the presentation of the COSO model; (c internal control and internal audit in public institutions; (d internal control issues in accounting regulations on the individual and consolidated annual financial statements; (e internal / managerial control; (f conclusions.

  6. Recent changes in precipitation extremes in Romania

    Adina-Eliza CROITORU


    Full Text Available Changes in daily extreme precipitations have been identified in many studies conducted at local, regional or global scales. In Romania, only little research on this issue has been done so far. The present study is focused on the analysis of the trends in daily extreme precipitations indices over a period of 53 years (1961-2013. Data sets of daily precipitation recorded in 34 weather stations were analyzed. Among them, three are located in the Carpathian Mountains area and four are located on the Black Sea Coast. The main goal was to find changes in extreme daily precipitation using a set of 13 indices adopted from the core indices developed by ETCCDMI with appropriate modifications to suit to the studied area. The series of the indices as well as their trends were generated using RClimDex software. The trends have been calculated using the linear mean square method. The findings are similar to those obtained at the global and European continental scales and the most noteworthy are: increasing trends dominate for the most of the indices, but only about 25% of them are statistically significant at α=0.05; decreasing trends are more specific to southern area of the country; decreasing trends of  R0.1, CDD and CWD dominate for the great majority of locations; the spatial distribution of the significant slopes in the area is extremely irregular.

  7. Knowledge Based Economy Assessment in Romania

    Sebastian Ion CEPTUREANU


    Full Text Available Knowledge and ability to create it, access and use effectively, has long been both an instrument of innovation and competition and a key economic and social development. However, a series of dramatic changes in recent years have increased the importance of knowledge for generating competitive advantage. Ability to process and use information globally and instantly increased exponentially in recent years due to a combination of scientific progress in computing and distributed computing, exacerbation of competition, innovation in all its forms and cuts of operating costs in global communication networks. As barriers to access knowledge regarding a process, product or market are gradually decreasing (distance, geographical features, and costs, knowledge and skills are becoming increasingly a key to competitiveness, both locally and globally. This paper, based on a survey of 551 Romanian companies, address a sensitive issue of both business and academic fields – perception of knowledge based economy in Romanian companies. Its conclusion can guide decision makers in Romania to develop an integrated approach to foster knowledge based economy in our country.

  8. Good prospects for green energy in Romania

    Mariana Papatulica


    Full Text Available EU has to attain the strategic objectives for 2020: 20% of energy from renewable sources, cutting the emissions of greenhouse gases by 20% and diminishing the dependence on imported fuels, that is why in the last years European Commission has decided that MS should increase the flexibility of programs to promote green energy and cut subsidies. Although wind and solar energy have become more competitive in terms of cost in the last two decades, many production technologies need to be improved, also storage and transport capacities. Romania has an important potential of renewable energy resources and has introduced a functional mechanism for supporting their development based on a system of mandatory quotas for electricity, combined with trading a number of green certificates, but all the costs are transferred to the consumers.This system may carry an overcompensation for the investors and also an excessive burden on the consumers. Most investments were made in wind and hydro, the fewest in solar and biomass. Market liberalization may create more competition and stimulate the investments in different renewable resources.




    Full Text Available Romania's alignment to European standards is a difficult process with many legislative changes, with direct impact on taxpayers. The necessity of collecting substantial revenues to the State budget, which provide vital economic growth of the Romanian State, loses the substance when we are talking about taxes levied in relation to taxpayer. The environmental stamp, otherwise a controversial tax, represent for the State another way to earn revenue in advance, “as a loan", because in the end it's forced to repay the amounts concerned taxpayers, under the effect of a final and irrevocable court decision. The effects of the legislative changes bring every time complaints both from taxpayers, because they can demand repayment of the environmental stamp only during the period of prescription, as well as on the part of public servants who are grappling with a large volume of work, with the possibility of overcoming the term to handle requests. An equitable solution in solving these distortions would be the inclusion of the environmental stamp within the tax on means of transport, tax that is paid annually by vehicle owners. At the moment the level of the environmental stamp is calculated depending on the CO2 emissions, exhaust emissions and the age of the vehicle. Tax on means of transport is calculated based on engine capacity, an amount determined by CO2 emissions multiplying with each group of 200 cc or fraction on it. Therefore the unification of the two taxes would create a balance for all categories of vehicles.

  10. Romania: Childbearing metamorphosis within a changing context

    Christin Schröder


    Full Text Available In 1989, the socialist regime in Romania collapsed and the state's coercive pro-natalist policy ended. Since then, fertility has gone through major changes, namely, a massive reduction in fertility and important structural changes: birth postponement, an end to universal childbearing, and the emergence of non-marital births. Family formation has been postponed, but a pattern of early marriage still persists compared to other European countries. Although unmarried cohabitation is rising, it is rarely seen as an alternative to marriage. Modern contraceptive methods are being used increasingly, but traditional contraceptive methods continue to be widespread. Abortion, which was re-legalized in 1989 and made available after two decades of prohibition, has been practiced extensively ever since, especially after first birth. Romanians in 2004 continue to have a universal preference for parenting. However, the preference for the two-child family has declined and the desire for a larger family has become the exception. The transformation of the socialist regime into a democratic society with a market economy generated a socio-economic crisis, and the majority of social benefits have therefore been oriented towards alleviating poverty. Other social policies, including those affecting the family, were redefined. However, fewer funds were made available than for those geared to promote economic development or reduce poverty and, as a consequence, their impact on childbearing has been small.

  11. Global asymptotic stabilisation in probability of nonlinear stochastic systems via passivity

    Florchinger, Patrick


    The purpose of this paper is to develop a systematic method for global asymptotic stabilisation in probability of nonlinear control stochastic systems with stable in probability unforced dynamics. The method is based on the theory of passivity for nonaffine stochastic differential systems combined with the technique of Lyapunov asymptotic stability in probability for stochastic differential equations. In particular, we prove that a nonlinear stochastic differential system whose unforced dynamics are Lyapunov stable in probability is globally asymptotically stabilisable in probability provided some rank conditions involving the affine part of the system coefficients are satisfied. In this framework, we show that a stabilising smooth state feedback law can be designed explicitly. A dynamic output feedback compensator for a class of nonaffine stochastic systems is constructed as an application of our analysis.

  12. Polarographic study on the evolution of the diphenylamine as stabiliser of the solid propellants.

    de Diego Martínez, A Pérez; Tascón, M L; Vázquez, M D; Sánchez Batanero, P


    Differential pulse polarography (DPP) and square wave voltammetry (SWV) were investigated, in order to know the stability of solid propellants which contain diphenylamine. The simultaneous determination of N-nitrousdiphenylamine (NnDPA), 2-nitrodiphenylamine (2nDPA), 4-nitrodiphenylamine (4nDPA) and 2,4-dinitrodiphenylamine (2,4dnDPA) by DPP and SWV was proposed due to these nitro-derivatives appear during the stabilisation process from degradation of diphenylamine (DPA) used as stabiliser in propellant compositions. The proposed methods were successfully applied to the simple base solid propellant (with nitrocellulose as the only active component), with its stabiliser DPA. In all cases and with both the techniques, detection limits propellants accurately, faster and cheaper than LC methods.

  13. Solidification/stabilisation of liquid oil waste in metakaolin-based geopolymer

    Cantarel, V.; Nouaille, F.; Rooses, A.; Lambertin, D.; Poulesquen, A.; Frizon, F.


    The solidification/stabilisation of liquid oil waste in metakaolin based geopolymer was studied in the present work. The process consists of obtaining a stabilised emulsion of oil in a water-glass solution and then adding metakaolin to engage the setting of a geopolymer block with an oil emulsion stabilised in the material. Geopolymer/oil composites have been made with various oil fraction (7, 14 and 20 vol.%). The rigidity and the good mechanical properties have been demonstrated with compressive strength tests. Leaching tests evidenced the release of oil from the composite material is very limited whereas the constitutive components of the geopolymer (Na, Si and OH-) are involved into diffusion process.

  14. Discrete-time reservoir engineering with entangled bath and stabilising squeezed states

    Miao, Zibo; Sarlette, Alain


    This theoretical proposal investigates how resonant interactions occurring when a harmonic oscillator is fed with a stream of entangled qubits allow us to stabilise squeezed states of the harmonic oscillator. We show that the properties of the squeezed state stabilised by this engineered reservoir, including the squeezing strength, can be tuned at will through the parameters of the ‘input’ qubits, albeit in tradeoff with the convergence rate. We also discuss the influence of the type of entanglement in the input from a pairwise case to a more widely distributed case. This paper can be read either as a proposal to stabilise squeezed states or as a step toward treating quantum systems with time-entangled reservoir inputs.

  15. Early Spin-Stabilised Rockets - the Rockets of Bergrat Heinrich Gottlob Kuhn

    Fricke, H.-D.

    19th century's war rockets were at first stabilised by sticks, but these sticks produced a very uncertain flight path and it often happened that rockets changed their direction and even flew back to their firing position. So very many early inventors in Europe, America, and British-India tried to stabilise the rocket's flight in a better way. They tried fins and even rotation but they did not succeed. It is said in history that William Hale was the first who succeeded in constructing a spin stabilised (i.e. rotating) rocket which worked. But before him, in the thirties of that century, a German amateur rocket inventor succeeded as well and secretly proved his stickless rotating rockets in trials for Prussian officers and some years later officially for Saxon artillery officers. His invention was then bought by the kingdom of Saxony, but these were never use in the field because of lack of money.

  16. Effective solidification/stabilisation of mercury-contaminated wastes using zeolites and chemically bonded phosphate ceramics.

    Zhang, Shaoqing; Zhang, Xinyan; Xiong, Ya; Wang, Guoping; Zheng, Na


    In this study, two kinds of zeolites materials (natural zeolite and thiol-functionalised zeolite) were added to the chemically bonded phosphate ceramic processes to treat mercury-contaminated wastes. Strong promotion effects of zeolites (natural zeolite and thiol-functionalised zeolite) on the stability of mercury in the wastes were obtained and these technologies showed promising advantages toward the traditional Portland cement process, i.e. using Portland cement as a solidification agent and natural or thiol-functionalised zeolite as a stabilisation agent. Not only is a high stabilisation efficiency (lowered the Toxicity Characteristic Leaching Procedure Hg by above 10%) obtained, but also a lower dosage of solidification (for thiol-functionalised zeolite as stabilisation agent, 0.5 g g(-1) and 0.7 g g(-1) for chemically bonded phosphate ceramic and Portland cement, respectively) and stabilisation agents (for natural zeolite as stabilisation agent, 0.35 g g(-1) and 0.4 g g(-1) for chemically bonded phosphate ceramic and Portland cement, respectively) were used compared with the Portland cement process. Treated by thiol-functionalised zeolite and chemically bonded phosphate ceramic under optimum parameters, the waste containing 1500 mg Hg kg(-1) passed the Toxicity Characteristic Leaching Procedure test. Moreover, stabilisation/solidification technology using natural zeolite and chemically bonded phosphate ceramic also passed the Toxicity Characteristic Leaching Procedure test (the mercury waste containing 625 mg Hg kg(-1)). Moreover, the presence of chloride and phosphate did not have a negative effect on the chemically bonded phosphate ceramic/thiol-functionalised zeolite treatment process; thus, showing potential for future application in treatment of 'difficult-to-manage' mercury-contaminated wastes or landfill disposal with high phosphate and chloride content.

    Full Text Available In this paper we wish to highlight the main causes of regional disparities in Romania in terms of absorption of European funds through Measure 313: Encouragement of tourism activities. The post-accession of Romania shows a major deficiency in attracting funds from the European Union, this situation is generated, in particular, by the lack of a coherent long-term vision of the authorities, insufficient resources for co-financing projects, low administrative capacity at central and local level, lack of inter-institutional coordination, public-private partnerships failures and insufficient skilled human resources . We will analyze the number of projects approved and implemented in each region of Romania (2007-2013 to establish the real possibilities of expansion of rural tourism.

    Full Text Available Following the events in Ukraine, Romania might represent one of the key points for the Eurasian perspectives that have circulated in the last years in Moscow. Through our text we intend to present and to highlight the main ideas and plans of Eurasian inspiration regarding Romania, as well as the interesting predictions made, in certain moments, by some representative characters for the Eurasian paradigm, like Aleksandr Dugin, for instance, who is its main ideologist and promoter. At the same time, one must not neglect the signals of discontent from Moscow about the need of dissipating the so-called sanitary cordon of the Western powers, in which the Baltic States, Poland, and Romania are included – another aspect bearing a particular importance for understanding certain gestures, attitudes and statements related to the role and the place of the Eurasian Union.

    Full Text Available In order to reach its economical and social potential, social economy must have a favorable environment, created through: establishing a strategic framework for development, fiscal and non-fiscal benefits, promoting it as the third sector between public and private, with its own dynamics. Since we are talking about a social business, financing sources are very important for starting or developing investment in the field. Through the article, the authors aim at making an analysis and recommendations for improvement of mechanisms of two financing sources – structural funds and bank loans. We wish to present a practical vision on strategic sustainable development of social economy in Romania, starting from the experience in the field the “Alaturi de Voi” Romania Foundation has had for the past seven years. Our foundation has managed to implement through the European Social Fund two strategic structural funds and to access a bank loan for the development of businesses of social enterprises from Romania.

  20. Demographic Evolution in Romania – Convergence or Peripherisation?

    Adriana Veronica Litra


    Full Text Available Romania began its demographic transition about one century later than the developed countries. We put the blame of this gap on the delayed economic, social and political development in comparison with the Western Europe. But also, it could not be forgotten the shift from a population forced and subdue by the totalitary regime, to a free people to decide when to have a child or how large should be the family. During transition, Romania has pointed many negative demographic evolutions, as compared with the other european countries. It may be said that the transition in Romania over the period 1990-2004 adjusted the classical pattern of demographic evolution. Not fully felt at this moment, we will probably find ourselves few decades later older, less, deprived of skilled labor force and unbalanced as gender ratio.

  3. Simulation Model for Foreign Trade During the Crisis in Romania

    Mirela Diaconescu


    Full Text Available The paper proposes to analyze the evolution of foreign trade during the crisis in Romania. The evolution of foreign trade is analyzed using a simulation model. The period of analysis is 2006-2014. The data source is Eurostat and National Bank of Romania. Also, based on these data, we propose an econometric model which can be developed using different scenarios and forecasting of evolution of foreign trade. In period of economic recession, protectionist sentiments against imports competing with domestic products tend to rise. The same phenomenon was manifested in Romania. Thus, our study started from this consideration. Using econometric model we made scenarios predictions and the results are similar to the real values.

  5. Romania's Agriculture and its Role in the Convergence Process



    Full Text Available The importance of agriculture in Romania is linked to the fact that 45% of its population is in the rural area, mostly dependent on agricultural activities. This paper aims to determine in what extent agriculture influences the convergence process of Romania with the euro area. The structural convergence index is computed in order to assess the degree in which the structure of the Romanian economy resembles the one of the euro area in terms of both gross value added and employment. Research indicates that Romania has the lowest score in terms of structural convergence with the euro area. The main reason is the oversized agricultural sector which employs almost a third of the active population. The productivity of the Romanian agriculture is then assessed in order to identify its possible effect on the country’s overall competitiveness and on the whole convergence process.

  6. Stable isotopic composition of bottled mineral waters from Romania

    Bădăluţă, Carmen; Nagavciuc, Viorica; Perșoiu, Aurel


    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.

  8. Determinants of Economic Growth in V4 Countries and Romania

    Simionescu Mihaela


    Full Text Available The middle and long-term slowdown in growth dynamics could bring serious social and political problems for V4 countries (Czech Republic, Slovak Republic, Hungary, Poland and Romania. It would threaten reaching benefits from potential of convergence process with the developed countries of the European Union. As a result, the V4 economies and Romania should find solutions to achieving a sustainable growth that is associated with an improvement of their international competitiveness. This paper provides an empirical analysis of factors that might determine a stable economic growth in the five mentioned countries. The empirical analysis conducted for the period of 2003-2016 employed Bayesian generalized ridge regression. The main results indicated that the FDI promoted economic growth in all countries, except the Slovak Republic. Only in the Czech Republic, the expenditure on education generated economic growth, while the expenditure on R&D had positive effects in Romania, Hungary and the Czech Republic.

  10. Free to Enterprise : Economic Freedom and Entrepreneurship In Romania

    Radu Ioan Şimandan


    Full Text Available In this article we analyze the relation between the economic freedom and the level of entrepreneurship in Romania. The widely used hypothesis that a free economic environment tend to generate high levels of entrepreneurship is discussed for the case of Romania. The evolution of a few fundamental features of the institutional environment for doing business in recent years is investigated, along with some measures of the level of entrepreneurship. A strong direct relation between economic freedom and entrepreneurship level was found for a large number of countries and geographic areas around the world. The available data does not allow us to make a quantitative analysis for Romania, but some suspected reasons for a direct relation between economic freedom and entrepreneurship level are presented. Future research directions are also suggested.




    Full Text Available Direct sale represents a modern product distribution system directly to consumers, generally, directly to their homes, to their workplace or other places, beside retail shops. The best known type of direct sale, the Network Marketing or Multilevel Marketing implies the existence of a network of distributors which earn income from selling on commission, to which they add the trade markup. This paper is based upon the analysis of these types of sales starting with the study of specialized literature especially by foreign authors, mainly Americans, with the analysis of statistical data presented by several organizations such as SELDIA (The European Direct Selling Association, MLM International Romania, ACVD (Association of Direct Selling Companies in Romania, as well as the legal regulations within this field. In conclusion, the paper presents an interesting comparison of the sales and structure volume between the Europe and Romania.

  12. Corporate Governance in Emerging Economies: The Case of Romania

    Niculae FELEAGĂ


    Full Text Available In Romania corporate governance has emerged beginning with the early 2000s. The delay is explainable by the difficult steps taken on the line of political, legal, economic and social reform. In recent years, however, the corporate governance environment in Romania has changed. Transparency and accountability have become key factors not only for shareholders, but also for investors, buyers, suppliers, and other stakeholders.In this context, it is worth to consider, based on statistical data, the degree of development of corporate governance in Romania. The selected indicators are linked to attributes of the Board of directors, in particular Board structure, size, independence, frequency of meetings, and other factors. The sources used are based on the official data published by companies listed on the Bucharest Stock Exchange (BSE. The results will be compared with results of other case studies of emerging countries and the European best practice.

  13. The direct Lyapunov method for the stabilisation of the Furuta pendulum

    Aguilar-Ibañez, Carlos; Suárez-Castañón, Miguel S.; Gutiérres-Frias, Oscar O.


    A nonlinear controller for the stabilisation of the Furuta pendulum is presented. The control strategy is based on a partial feedback linearisation. In a first stage only the actuated coordinate of the Furuta pendulum is linearised. Then, the stabilising feedback controller is obtained by applying the Lyapunov direct method. That is, using this method we prove local asymptotic stability and demonstrate that the closed-loop system has a large region of attraction. The stability analysis is carried out by means of LaSalle's invariance principle. To assess the controller effectiveness, the results of the corresponding numerical simulations are presented.

  14. Novel use of hand fracture fixation plates in the surgical stabilisation of flail chest.

    Dunlop, Rebecca L E


    Plastic surgeons specialize in working closely with other surgical colleagues to help solve clinical problems. In this case, we performed surgical stabilisation of a large flail chest fragment in conjunction with the cardiothoracic surgical team, using the mini-plating set more commonly used for hand fracture fixation. The use of this fixation system for flail chest has not previously been described, but offers advantages over other reported methods, primarily by dispensing with the need for an extensive thoracotomy incision and by providing robust stabilisation without the presence of prominent hardware.

  15. Stabilisation for switched linear systems with time-varying delay and input saturation

    Chen, Yonggang; Fei, Shumin; Zhang, Kanjian


    This article investigates the stabilisation problems for continuous-time and discrete-time switched systems with time-varying delay and saturated control input. Based on dwell time switching signals and multiple Lyapunov functional method, stabilisation conditions are well obtained in the context of linear matrix inequalities. To estimate attractive regions as large as possible, the feasibility problems are translated into optimisation problems. In addition, the corresponding results are presented for linear time-delay systems and switched delay-free systems, which improve and supplement some existing ones in the literature. Finally, numerical examples and simulations are given to illustrate the effectiveness and values of the proposed results.

  16. Noise-cancelled, cavity-enhanced saturation laser spectroscopy for laser frequency stabilisation

    Vine, Glenn de; McClelland, David E; Gray, Malcolm B [Centre for Gravitational Physics, Faculty of Science, Australian National University, Canberra, ACT 0200 (Australia)


    We employ a relatively simple experimental technique enabling mechanical-noise free, cavityenhanced spectroscopic measurements of an atomic transition and its hyperfine structure. We demonstrate this technique with the 532 nm frequency doubled output from a Nd:YAG laser and an iodine vapour cell. The resulting cavity-enhanced, noise-cancelled, iodine hyperfine error signal is used as a frequency reference with which we stabilise the frequency of the 1064nm Nd:YAG laser. Preliminary frequency stabilisation results are then presented.

  17. Social grievances, popular music and electoral mobilization in Romania

    Dragoş DRAGOMAN


    Full Text Available The general social environment in Romania, as unraveled by the study of a widespread popular music genre called ‘manele’, is dominated by distrust, apathy and disengagement. In part, this is a response to the low political performance of political elites, largely seen as irresponsible and corrupt. By exploiting social and political grievances through the use of such a type of popular music, populist parties in Romania managed to electorally mobilize young people which have not been mobilized before. Although this can be seen as a democratic gain, hate speech and political violence can seriously undermine social and political trust and may prepare the ground for more radical action.

  18. Particularities of youth unemployment and the labour market in Romania

    Gabriela RÎMBU


    Full Text Available Youth unemployment has become a priority for the European Union. The globalisation, the cyclical economic changes and the fast evolution of the labour market require new public policy and new approaches in order to stimulate integration of the young people into the labour market. This paper intends to highlight the effects and efficiency of the public policy that supports the labour market in the European Union and Romania. The conclusion is that Romania is adopting important measures for facilitating the employment of young people and decreasing unemployment, but the implemented measures and strategies have registered limited progress and more innovative solutions are needed.




    Full Text Available The paper reviews the concepts and strategies regarding sustainable development in European Union and Romania. The concept of sustainable development is built on the premise that human civilization is a sub-system of the Ecosphere and is dependent on its material and energy flows, on its stability and capacity for selfadjustment.Sustainable development is a common objective and a permanentpreoccupation of the European Union Member States. For Romania as a Member State of the European Union, sustainable development is not one of several possible options, but the only rational prospect for advancement as a nation.

This paper follows a “classical” approach, with a focus on the pros and cons of the Public-Private Partnership concept, legal forms met in the European acquis, the Eurostat view on such projects in terms of the statistical classification of assets, financing and policy directions in the European Union and lessons learnt for practitioners in Romania, while taking into account the recent developments of the PPP market in the European Union




    Full Text Available Financial side of local autonomy expresses the capacity of local communities to have their own revenue and expenditure budget, distinct from that of the state in which revenues can cover expenses incurred to meet their requirements. The analysis of financial autonomy of administrative-territorial units in Romania is an interesting but complex approach given that some factors are actually difficult to predict and quantify.The purpose of this paper is to clarify the meaning of financial side of local autonomy and analyze this in Romania based on indicators established in recent years for measuring the position of administrative-territorial units in relation to central government.

  4. Institutions fighting Trafficking in Human Beings in the Contemporary Romania

    Lia Pop


    Full Text Available In the last approximately 15 years, mainly in the last decade, Romania made substantial efforts to establish the institutions fighting THB according with the EU’s Directive 38 /2011’s requirements and the recommendation assumed by the International Treaties signed and ratified in this area. The plethora of institutions were founded, but they are not functioning yet as a system because of the absence of the independent assessing institution. That is why, it must be, immediately, created. Beside, the institutional system needs, as a unavoidable complement the launching of Cultural Strategy in tabooing for good, the THB in Romania.

    Full Text Available Health tourism occupies an important place in the preferences of tourists and represents one of the major sources of revenue for Romania, a country rich in resources spas. Romania holds spas with tourism potential, but which require investments in infrastructure, to work to the standards required of a modern tourism. The need of valorization of balneology potential of the regions to increase regional competitiveness, global and national, has led to the appearance of PPP forms adapted to the particularities of the tourist industry. We develop a collaborative model in which the balneology destinations can become leaders of European health tourism.

  9. Economic and Banking Environment in Romania and E.U.



    Full Text Available The study presents the overall picture of Europe's economic prospects, strained relations within the European area. Also presents the evolution of the banking system in Romania in the context of situations in Europe, which returned to profit and record high levels of solvency and liquidity, while the NPL ratio continued to decline. Due to the difficulty of forecasting medium business, and to the macroeconomic context, banks avoid risk taking associated finance investment projects in the long term, preferring financing in the medium term, so that more than half of home loans granted in Romania are for term funding short and medium.

  11. The State-Church Relationship in Post-Communist Romania



    Full Text Available Starting from the Romanian edition of Lavinia Stan and Lucian Turcescu’swork Religion and Politics in Post-Communist Romania, we argue in favour of thenecessity to study the relationship between the State and the Romanian OrthodoxChurch using an approach which takes into account the details and the possibleexistent perspectives, bringing a plus of objectivity, which is so needed in a fieldperceived as a sensible one. The arguments put forward will be justified by thehistorical tradition of the State-Church relationship in the Byzantine Empire, but alsoin Romania, as well as by the predominantly Orthodox structure of our country.

  14. The Professionalization of Public Administration in Romania

    Mihaela V. Cărăuşan


    Full Text Available The general configuration of the state and its responsibilities has changed and this has introduced important modifications both in the policy arena and in the State’s requirements for high-level skills, qualitatively and quantitatively. Even if Romanian public administration is mainly seen as bureaucratic, oversized and unable to attract the best trained civil servants, the issue of the professionalization of its human resources has never been brought to the fore. Moreover, public functions are not included in the category of the most desired ones the vast majority of people try to obtain such a job, considering that it provides stability. Turnaround professional qualification indicates the rate of experience, knowledge, and integrity necessary to conduct renewal work. Unfortunately, formal barriers hindering the promotion (e.g. waiting time, professional seniority and limited development opportunities (flat management structures, lack of visible career paths, inadequate information on vacancies have a negative impact on the degree of motivation and commitment at work, and of course they adversely affect service quality. In this regard we undertake a study among students and graduates of schools of public administration in Romania, Bucharest, from which we determine the worst and the best 10 jobs you can get today in public administration. Moreover, we will seek to find out which is their motivation to have an education in administrative sciences. Also, we focus our attention on those employed in public institutions to pursue their professional route and their professional qualification. Once established, we will endeavour to create the axis of professional career in public administration. This research will hold a discussion on professional qualification, articulated with the unemployment caused by the present crisis. It will aim to demonstrate the consolidation of the professional (disqualification as a tool. We will see that professional

    Full Text Available The importance of the local public finance is growing in accordance with the increasing proportion of the decentralization process. The mechanism of resource allocation, and especially the allocation criteria used, constitutes subjects of debate. Our objective pursued is to assess whether the avoidance of the first step for balancing the allocation of funds can provide enhanced fairness in balancing the local budgets across the country. Local budgets in Romania receive significant resources from the state budget in the form of amounts and quotas distributed from certain taxes, which are revenues for the state budget. Some of these amounts are designed to balance the local budgets. The distribution of funds from the state budget to the local budgets requires two steps. Firstly, the amounts are divided by county, secondly, these amounts are directed within the county especially towards localities which have a lower financial standing. Given the significant disparities between counties, we believe that this mechanism does not ensure fairness in the allocation because the funds distributed according to the first step may not use fair criteria to meet the requirements for balanced local budgets. Therefore, we intend to simulate a balanced allocation of national funds for eliminating the first step that produces the most significant inequities. Direct application of the second step of allocation, with its two phases, will provide more funds serving those local administrative units for the income tax per capita is lower than the national average. Comparing the values allocated for the year 2011 with those obtained in the simulation we will examine changes that occur after the application of this method which seems to be more equitable and appropriate.

  5. Measurement of wind profiles by motion-stabilised ship-borne Doppler lidar

    P. Achtert


    Full Text Available Three months of Doppler lidar wind measurements were obtained during the Arctic Cloud Summer Experiment on the icebreaker Oden during the summer of 2014. Such ship-borne measurements require active stabilisation to remove the effects of ship motion. We demonstrate that the combination of a commercial Doppler lidar with a custom-made motion-stabilisation platform enables the retrieval of wind profiles in the Arctic boundary layer during both cruising and ice-breaking with statistical uncertainties comparable to land-based measurements. This holds particularly within the planetary boundary layer even though the overall aerosol load was very low. Motion stabilisation was successful for high wind speeds in open water and the resulting wave conditions. It allows for the retrieval of winds with a random error below 0.2 m s−1, comparable to the measurement error of standard radiosondes. The combination of a motion-stabilised platform with a low-maintenance autonomous Doppler lidar has the potential to enable continuous long-term high-resolution ship-based wind profile measurements over the oceans.

    Achtert, P.; Brooks, I. M.; Brooks, B. J.; Moat, B. I.; Prytherch, J.; Persson, P. O. G.; Tjernström, M.


    Three months of Doppler lidar wind measurements were obtained during the Arctic Cloud Summer Experiment on the icebreaker Oden during the summer of 2014. Such ship-borne Doppler measurements require active stabilisation to remove the effects of ship motion. We demonstrate that the combination of a commercial Doppler lidar with a custom-made motion-stabilisation platform enables the retrieval of wind profiles in the Arctic atmospheric boundary layer during both cruising and ice-breaking with statistical uncertainties comparable to land-based measurements. This held true particularly within the atmospheric boundary layer even though the overall aerosol load was very low. Motion stabilisation was successful for high wind speeds in open water and the resulting wave conditions. It allows for the retrieval of vertical winds with a random error below 0.2 m s-1. The comparison of lidar-measured wind and radio soundings gives a mean bias of 0.3 m s-1 (2°) and a mean standard deviation of 1.1 m s-1 (12°) for wind speed (wind direction). The agreement for wind direction degrades with height. The combination of a motion-stabilised platform with a low-maintenance autonomous Doppler lidar has the potential to enable continuous long-term high-resolution ship-based wind profile measurements over the oceans.

    Full Text Available Studies on furan resin as dune sand stabiliser are presented. Influence of acid catalysts, viz. phenol disulphonic acid, sulphuric acid, hydrochloric acid and phosphoric acid and other catalysts, viz. trichlorotoluene and benzoyl chloride along with promoters, zinc chloride and ferric chloride, on the strength of stabilised furan resin-sand specimens has been discussed. Optimisation studies on resin content, catalysts and promoters and curing conditions have revealed that maximum strength of 260 kg/cm/sup 2/ of the standard specimens made by compaction of coastal sand using furan resins (10 per cent, sulphuric acid (9N, 30 per cent and a curing time of 2 hr at 40 degree Centigrade is higher than the 170 kg/cm/sup 2/ of specimens made of Rajasthan desert sand. Sandy patches stabilised by seepage technique recorded a maximum strength of 125 kg/cm/sup 2/. Physico-chemical characteristics of this system and effect of environment on stabilised specimens have also been studied and field trials conducted successfully. This resin-catalyst system would be extremely useful in humid and saline field (coastal areas for different military applications.

In addition, we were able to identify the first tertiary amine-based chiral auxiliary that allows for high enantioselectivities and high yields for such epoxidation reactions.

  15. A numerical procedure to compute the stabilising solution of game theoretic Riccati equations of stochastic control

    Dragan, Vasile; Ivanov, Ivan


    In this article, the problem of the numerical computation of the stabilising solution of the game theoretic algebraic Riccati equation is investigated. The Riccati equation under consideration occurs in connection with the solution of the H ∞ control problem for a class of stochastic systems affected by state-dependent and control-dependent white noise and subjected to Markovian jumping. The stabilising solution of the considered game theoretic Riccati equation is obtained as a limit of a sequence of approximations constructed based on stabilising solutions of a sequence of algebraic Riccati equations of stochastic control with definite sign of the quadratic part. The proposed algorithm extends to this general framework the method proposed in Lanzon, Feng, Anderson, and Rotkowitz (Lanzon, A., Feng, Y., Anderson, B.D.O., and Rotkowitz, M. (2008), 'Computing the Positive Stabilizing Solution to Algebraic Riccati Equations with an Indefinite Quadratic Term Viaa Recursive Method,' IEEE Transactions on Automatic Control, 53, pp. 2280-2291). In the proof of the convergence of the proposed algorithm different concepts associated the generalised Lyapunov operators as stability, stabilisability and detectability are widely involved. The efficiency of the proposed algorithm is demonstrated by several numerical experiments.

    Full Text Available The paper aims to analyze the evolution and use of integrated ERP systems on the Romanian market during the crisis. In the context of the more developed markets as in Romania like those in France, Germany and Austria but also in Poland, Czech Republic or Russia, which shows clear signs of a sustained demand for complex business solutions, ERP domestic market remains stagnant or slightly oscillates around the same values and no signs of recovery before 2014. Thus, according to PAC studies (market analysis company Pierre Audoin Consultants in 2009, the local ERP market demand, decreased much stronger than on the entire market for software and IT services in Romania. In 2012, only 105 million euro were invested for new or the maintenance of ERP projects already implemented in previous years, proves that Romania has one of the worst appetites of Europe, reflecting the functioning of the economy and of the public sector but also of the default public administration. While in most countries in Europe, public administration accelerates adoption of ERP solutions with processes and functionalities already developed and important references, Romania still prefer to develop specific systems, sometimes around general ERP modules, without real references in the field

  1. Evolution and consequences of economic crisis in Romania

    Gina IOAN


    Full Text Available The paper treats the main Romania's macroeconomic indicators before and after the economic crisis began. It is determined a set of correlations of population occupancy level by investment in key sectors. Also, finally, it is determined the Okun's law in Romania. The analysis reveals that a higher occupancy labor will implicitly lead to an increase in the GDP. On the other hand, the structure and nature of investment in Romania must be redesign, in the purposes of achieving a compromise between technology and creating jobs. An increase in training of the population, fostering integration of graduates (especially those with secondary and higher education in the labor market and limit migration will lead to increased investment in high efficiency especially in industry and a highly competitive on foreign markets. Also, a higher labor efficiency will increase the Okun’s coefficient (1.72 for Romania as compared with 2 in most developed countries so a higher potential GDP growth relative to labor.




    Full Text Available This paper aims to synthesize main aspects regarding the implementation of the information society in Romania in the the current period of post-accession to European Union. This approach of scientific research is based essentially on a set of official documents between which are highlighted National Strategy on the Digital Agenda for Romania 2020, corroborated with Digital Agenda for Europe. In this sense, it is important to mention that the Information Society (IS involves not only a rethinking of the way in which Romanian companies should identify efficiency and performance solutions to requirements of more ever specialized consumers, which could allow to maintain on the advantageous positions ahead of stiff trade competition intra and extra EU trade competition but also a greater awareness of behavior and valorisation mutations generated by the complexity of globalization phenomenon which could appear at national consciousness level. Also in the equation process of Romania's integration into the paradigm of information society, the innovation and technological changeshave an important role in achieving economic performances and changes in their dynamic, that can irreversibly influence the mechanism for implementing the strategies of modernization, growth and sustainable development. Finally, it is important to emphasize that from this perspective it is porposed only a schematic approach to the framework of IS implementation in Romania, without the intention of making an exhaustive presentation of the issue highlighted in this paper.

  5. A strategic assessment of abortion and contraception in Romania.

    Johnson, Brooke R; Horga, Mihai; Fajans, Peter


    The history of fertility regulation in Romania illustrates the complex interactions between politics, women's reproductive health and rights and access to high quality care. This paper describes the current situation of abortion and contraception in Romania, based on national statistics, recent reproductive health surveys and the findings of a strategic assessment led by the Ministry of Health in late 2001. This rapid assessment employed a participatory, qualitative methodology. Over 500 people were interviewed from 145 institutions in 25 cities, towns and villages in Romania, about the range of actions needed to prevent unwanted pregnancies, reduce abortion-related morbidity and mortality and improve the quality, accessibility and availability of abortion and contraceptive services. Although much progress has been made in contraceptive services over the past ten years, improvements in abortion care have lagged considerably The assessment played an important role in raising team members' awareness and motivation to take action. Some of the issues identified are already being addressed by the institutions that took part. National standards and guidelines for comprehensive abortion care have been developed, contraceptive services have been expanded at primary health care level, sexual and reproductive health education provided by classroom teachers has been introduced in schools, and a study to test a model of comprehensive abortion care services for Romania is planned.

  13. Theoretical Aspects of the Economic Transition: The Case of Romania

    Cezar Scarlat


    Full Text Available For Romania, as for all other ex-communist countries from Eastern Europe, the transition from the rigid centrally planned economic system to the free-market economy, fair competition based, was an amazing experience. From the academic standpoint, the economic reform was a huge research opportunity, as well as having extremely important practical consequences. Based on the case of Romania, the authors have developed an original, bi-dimensional matrix model of this transition process (Scarlat Model, emphasizing the typology of four basic economic systems. Managerial aspects are underlined – both for economic systems and transition process – as well as some stability considerations. Two features of the transition strategy are presented: the transition path and duration of the process. Special attention was paid to assessing the moment by when the economic transition ends. Analysis of the transition path – based on the theory of deterministic chaos (i.e. short-run predictability – has led to interesting results: a comprehensive research on the evolution of the Romanian currency exchange over a period of sixteen years (1990–2005 revealed three intervals in the Romanian recent history of economic transition and confirmed the diagnostic of transition end. The general model is applied in the case of Romania and some interesting findings are presented, but it is also fully applicable to all Eastern European countries and not only Romania. The EU accessing process is a different type of transition – rigorously planned, regulated and monitored.

  2. Fiscal and Financial Stability in Romania - An Overview

    Florin OPREA


    Full Text Available The recent financial crisis has seriously shaken economies around the world, and raised serious doubts about the long-term viability of the public policies to remedy market imperfections. The effect has been pronounced for Romania, a newly transitioned country with a fragile market economy due to political, economic and social consequents. This paper examines the correlation between fiscal policy and financial stability in Romania in the period from 1990 to 2011. Specifically, we analyze the country’s main monetary and fiscal policy decisions and their associations with macro-economic variables, highlighting the requirements for a sustainable macro-economic policy and whether such requirements have been met in Romania. Based on the results, we further outline recommendations to improve Romania’s public policy initiatives, considering the specific correlations between monetary and fiscal policies. The results for the period under study indicate that fiscal and monetary policies promoted in Romania have not been consistently harmonized, at times lacking necessary mutual support, or even generating conflicting outcomes favorable to the manifestation of fiscal and financial instability.

  5. Towards 12% stabilised efficiency in single junction polymorphous silicon solar cells: experimental developments and model predictions

    Abolmasov Sergey


    Full Text Available We have combined recent experimental developments in our laboratory with modelling to devise ways of maximising the stabilised efficiency of hydrogenated amorphous silicon (a-Si:H PIN solar cells. The cells were fabricated using the conventional plasma enhanced chemical vapour deposition (PECVD technique at various temperatures, pressures and gas flow ratios. A detailed electrical-optical simulator was used to examine the effect of using wide band gap P-and N-doped μc-SiOx:H layers, as well as a MgF2 anti-reflection coating (ARC on cell performance. We find that with the best quality a-Si:H so far produced in our laboratory and optimised deposition parameters for the corresponding solar cell, we could not attain a 10% stabilised efficiency due to the high stabilised defect density of a-Si:H, although this landmark has been achieved in some laboratories. On the other hand, a close cousin of a-Si:H, hydrogenated polymorphous silicon (pm-Si:H, a nano-structured silicon thin film produced by PECVD under conditions close to powder formation, has been developed in our laboratory. This material has been shown to have a lower initial and stabilised defect density as well as higher hole mobility than a-Si:H. Modelling indicates that it is possible to attain stabilised efficiencies of 12% when pm-Si:H is incorporated in a solar cell, deposited in a NIP configuration to reduce the P/I interface defects and combined with P- and N-doped μc-SiOx:H layers and a MgF2 ARC.

  8. Influence of grazing practices on cow milk quality: a case study on the Comarnic-Poieni bauxite quarry, Romania.

    Lorinţ, Csaba; Rădulescu, Monica; Buia, Grigore


    The current study represents a preliminary investigation made into the influence of cattle grazing in the area of a bauxite quarry (Comarnic-Poieni, Romania) on the cow milk chemistry. Weathering and surface runoff in the bauxite quarry contaminate the local chemistry of the soil, vegetation and water. During cattle transhumance, cyclic feeding patterns occur, with grazing alternating between clean pastures and the area of the quarry. Soil and water samples were collected from the contaminated area of the quarry. Raw milk samples were collected during two stages, corresponding to the periods of grazing on clean pasture and the quarry area, respectively. Based on the obtained data, the relationship between cattle grazing and the composition of milk was interpreted. Preliminary results indicated a direct correlation of increased concentration of Al in the milk, following grazing in the bauxite quarry.

  9. The impact of climatic and non-climatic factors on land surface temperature in southwestern Romania

    Roşca, Cristina Florina; Harpa, Gabriela Victoria; Croitoru, Adina-Eliza; Herbel, Ioana; Imbroane, Alexandru Mircea; Burada, Doina Cristina


    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.

  12. The use of muscle dynamometer for correction of muscle imbalances in the area of deep stabilising spine system.

    Malátová, Renata; Rokytová, Jitka; Stumbauer, Jan


    Dorsal pain caused by spine dysfunctions belongs to most frequent chronic illnesses. The muscles of the deep stabilising spine system work as a single functional unit where a dysfunction of only one muscle causes dysfunction of the whole system. Non-invasive, objective and statistically measurable evaluation of the condition of deep stabilising spine system has been made possible by the construction of muscular dynamometer. The aim of our work has been the assessment of deep stabilising spine system by diaphragm test and muscular dynamometer measurements. Based on an initial examination, a 6-week intervention programme was established including instructions on physiological body posture and correct basic body stabilisation for the given exercises and muscle strengthening. Consecutive measurements are then compared with the initial ones. It was presumed that a smaller number of the tested subjects would be able to correctly activate the deep stabilising spine system muscles before the intervention programme when compared to those after the intervention programme. A positive change of 87% has been found. It is clear that if a person actively approaches the programme, then positive adaptation changes on the deep stabilising spine system are seen only after 6 weeks. With the muscular dynamometer, activation of deep stabilising spine system can be objectively measured. Changes between the initial condition of a subject and the difference after some exercise or rehabilitation are especially noticeable. Also, the effect of given therapy or correct performance of the exercise can be followed and observed.

    Full Text Available Plant functional traits and plant functional groups are increasingly used to assess the effect of the change in land use on plant species or plant communities, in nature conservation projects, to detect patterns in the expansion some invasive species or to asses the processes of succession or competition in plant communities. In this study, the main objective was to identify the main plant functional groups (based on plant traits which co-exist in different plant communities of the dry grasslands (Festucetalia valesiacae from North-Eastern Romania using the RLQ analysis (considering the plant traits, environment characteristics and vegetation. As RLQ analysis mainly revealed a soil moisture-soil nutrients gradient along the first axis, a transition from species with traits specific to more dry conditions and less available nutrients to moister and higher nutrients availability sites was observed (from perennial species with short flowering range and traits oriented to resources retention in storage organs to annual species with long flowering range and traits oriented to resource acquisition. Plant functional groups were identified using species scores along the first two RLQ axes via k-means clustering which generated six groups displayed along the above mentioned gradients. The floristic composition of the identified functional groups suggested that, in the context of Festucetalia valesiacae vegetation type from North-Eastern Romania, plant communities developed in areas with lower values for soil moisture and nutrients could possibly be richer in autochore and barochore geophyte and hemicryptophyte species with short flowering range and mixed reproduction type. As soil moisture and nutrients increase, in the floristic composition could possibly occur more anthropochore and zoochore therophyte species with long flowering range, mainly reproducing by seeds and, also, some taller endozoochore shrubs species.

  14. Use of mycorrhizal fungi for the phyto stabilisation of radio contaminated environment (European project myrrh): overview on the scientific achievements

    Dupre De Boulois, H.; Leyval, C.; Joner, E.J.; Jakobsen, I.; Chen, B.; Roos, P.; Thiry, I.; Rufyikiri, G.; Delvaux, B.; Declerck, S. [Universite catholique de Louvain, Mycotheque de l' Universite catholique de Louvain (MUCL), Unite de Microbiologie, Louvain-la-Neuve (Belgium)


    Because plants significantly affect radionuclides (RN) cycling and further dispersion into the biosphere, it is important to understand the biological factors influencing RN plant uptake, accumulation and redistribution. In this respect, mycorrhizal fungi which are intimately associated with plant roots and constitute an active continuum at the soil-plant interface are of particular interest. The European project MYRRH (Use of Mycorrhizal fungi for the phyto-stabilisation of radio-contaminated environment) was aimed to highlight the role of these soil micro-organisms. Both ectomycorrhizal (ECM) and arbuscular mycorrhizal (AM) fungi were considered and experiments were performed using naturally or artificially contaminated substrates with radiocaesium (Cs) or uranium (U) under pot culture or in vitro conditions. Results obtained under in vitro conditions demonstrated that AM fungal hyphae could take up and trans-locate Cs and U towards roots. However, this translocation was low for both elements. In particular, for Cs, uptake and translocation were not even perceptible using a classical pot culture system, but these contrasting results should be related to the growth conditions (e.g. concentration of potassium) used. The efficiency of translocation (rate of translocation per unit area) of both elements under in vitro conditions was higher than the one of roots. The in vitro studies also showed that the intra-radical AM fungal structures might contribute to Cs and U accumulation within mycorrhizal roots. Under pot culture conditions, AM fungi appeared to significantly reduce root to shoot translocation of U. Under the same conditions, ECM transport of Cs was demonstrated, and appeared to be dependent on the fungal species. As we established that mycorrhizal fungi could influence RN plant acquisition, accumulation and redistribution, a better estimation of the potential use of mycorrhizal fungi for the phyto-remediation of RN-contaminated areas is now available 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, ( 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

  16. Sediment budget for Rediu reservoir catchment, North-Eastern Romania

    Todosi, Cristian; Niculita, Mihai


    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

  17. EMDR versus stabilisation in traumatised asylum seekers and refugees: results of a pilot study

    Rolf J. Kleber


    Full Text Available Traumatised asylum seekers and refugees are clinically considered a complex population. Discussion exists on whether with this population treatment guidelines for post-traumatic stress disorder (PTSD should be followed and Trauma-Focused Cognitive-Behavioural Therapy (TF-CBT or Eye Movement Desensitisation and Reprocessing (EMDR should be applied, or whether a phased model starting with stabilisation is preferable. Some clinicians fear that trauma-focused interventions may lead to unmanageable distress or may be ineffective. While cognitive-behavioural interventions have been found to be effective with traumatised refugees, no studies concerning the efficacy of EMDR with this population have been conducted as yet.In preparation for a randomised trial comparing EMDR and stabilisation with traumatised refugees, a pilot study with 20 participants was conducted. The objective was to examine feasibility of participation in a randomised trial for this complex population and to examine acceptability and preliminary efficacy of EMDR.Participants were randomly allocated to 11 sessions of either EMDR or stabilisation. Symptoms of PTSD (SCID-I, HTQ, depression and anxiety (HSCL-25, and quality of life (WHOQOL-BREF were assessed at pre- and post-treatment and 3-month follow-up.Participation of traumatised refugees in the study was found feasible, although issues associated with complex traumatisation led to a high pre-treatment attrition and challenges in assessments. Acceptability of EMDR was found equal to that of stabilisation with a high drop-out for both conditions. No participants dropped out of the EMDR condition because of unmanageable distress. While improvement for EMDR participants was small, EMDR was found to be no less efficacious than stabilisation. Different symptom courses between the two conditions, with EMDR showing some improvement and stabilisation showing some deterioration between pre-treatment and post-treatment, justify the conduct

    Ludu Oslobanu, Elena Luanda; Mihu-Pintilie, Alin; Anită, Dragos; Anita, Adriana; Lecollinet, Sylvie; Savuta, Gheorghe


    The presence of West Nile virus (WNV) in humans has been known in Romania since the 1950s; the 1996 epidemics emphasized the reemergence potential of WNV in Romania. Serological surveys made on susceptible species, known as good sentinels or reservoir hosts, e.g., horses, wild and domestic birds were undertaken from 2006-2011. Our results corroborated incidence data in human patients and other recent seroprevalence studies in animals, and should partially clarify the emergence of WNV in the eastern rural territories of Romania. It also highlighted risk zones for endemic WNV infection in Romania.

  2. A Scott bench with ergonomic thorax stabilisation pad improves body posture during preacher arm curl exercise.

    Biscarini, Andrea; Benvenuti, Paolo; Busti, Daniele; Zanuso, Silvano


    We assessed whether the use of an ergonomic thorax stabilisation pad, during the preacher arm curl exercise, could significantly reduce the excessive shoulder protraction and thoracic kyphosis induced by the standard flat pad built into the existing preacher arm curl equipment. A 3D motion capture system and inclinometers were used to measure shoulder protraction and thoracic kyphosis in 15 subjects performing preacher arm curl with a plate-loaded machine provided with the standard flat pad. The same measures were repeated after replacing the flat pad with a new ergonomic pad, specifically designed to accommodate the thorax profile and improve body posture. Pad replacement significantly (p thorax stabilisation pad for the preacher arm curl exercise. The new ergonomic pad improves the poor posture conditions induced by the standard flat pad and may potentially allow a more effective training, prevent musculoskeletal discomfort, improve the breathing function and reduce the risk of injury.

  3. The streamline upwind Petrov-Galerkin stabilising method for the numerical solution of highly advective problems

    Carlos Humberto Galeano Urueña


    Full Text Available This article describes the streamline upwind Petrov-Galerkin (SUPG method as being a stabilisation technique for resolving the diffusion-advection-reaction equation by finite elements. The first part of this article has a short analysis of the importance of this type of differential equation in modelling physical phenomena in multiple fields. A one-dimensional description of the SUPG me- thod is then given to extend this basis to two and three dimensions. The outcome of a strongly advective and a high numerical complexity experiment is presented. The results show how the version of the implemented SUPG technique allowed stabilised approaches in space, even for high Peclet numbers. Additional graphs of the numerical experiments presented here can be downloaded from

  4. Vibration-displacement measurements with a highly stabilised optical fiber Michelson interferometer system

    Xie, Fang; Ren, Junyu; Chen, Zhimin; Feng, Qibo


    A highly stabilised vibration-displacement measurement system, which employs fiber Bragg gratings (FBGs) to interleave two fiber Michelson interferometers that share the common-interferometric-optical path, is presented. The phase change in the interferometric signals of the two fiber Michelson interferometers have been tracked, respectively, with two electronic feedback loops. One of the fiber interferometers is used to stabilise the system by the use of an electronic feedback loop to compensate the environmental disturbances. The second fiber interferometer is used to perform the measurement task and employs another electronic feedback loop to track the phase change in the interferometric signal. The measurement system is able to measure vibration-displacement and provide the sense of direction of the displacement. The frequency range of the measured vibration-displacement is from 0.1 to 200 Hz and the measurement resolution is 10 nm.

  5. Green synthesis of highly concentrated aqueous colloidal solutions of large starch-stabilised silver nanoplatelets.

    Cheng, Fei; Betts, Jonathan W; Kelly, Stephen M; Hector, Andrew L


    A simple, environmentally friendly and cost-effective method has been developed to prepare a range of aqueous silver colloidal solutions, using ascorbic acid as a reducing agent, water-soluble starch as a combined crystallising, stabilising and solubilising agent, and water as the solvent. The diameter of silver nanoplatelets increases with higher concentrations of AgNO3 and starch. The silver nanoparticles are also more uniform in shape the greater the diameter of the nanoparticles. Colloidal solutions with a very high concentration of large, flat, hexagonal silver nanoplatelets (~230 nm in breadth) have been used to deposit and fix an antibacterial coating of these large starch-stabilised silver nanoplates on commercial cotton fibres, using a simple dip-coating process using water as the solvent, in order to study the dependence of the antibacterial properties of these nanoplatelets on their size.

  6. Femtosecond fibre laser stabilisation to an optical frequency standard using a KTP electro-optic crystal

    Nyushkov, B N [Novosibirsk State University, Novosibirsk (Russian Federation); Pivtsov, V S; Koliada, N A [Institute of Laser Physics, Siberian Branch, Russian Academy of Sciences, Novosibirsk (Russian Federation); Kaplun, A B; Meshalkin, A B [S.S. Kutateladze Institute of Heat Physics, Siberian Division of the Russian Academy of Sciences, Novosibirsk (Russian Federation)


    A miniature intracavity KTP-based electro-optic phase modulator has been developed which can be used for effective stabilisation of an optical frequency comb of a femtosecond erbiumdoped fibre laser to an optical frequency standard. The use of such an electro-optic modulator (EOM) has made it possible to extend the working frequency band of a phase-locked loop system for laser stabilisation to several hundred kilohertz. We demonstrate that the KTP-based EOM is sufficiently sensitive even at a small optical length, which allows it to be readily integrated into cavities of femtosecond fibre lasers with high mode frequency spacings (over 100 MHz).

  7. P-Stereogenic Phosphines for the Stabilisation of Metal Nanoparticles. A Surface State Study

    Eva Raluy


    Full Text Available Palladium and ruthenium nanoparticles have been prepared following the organometallic precursor decomposition methodology, under dihydrogen pressure and in the presence of borane protected P-stereogenic phosphines. NMR (Nuclear Magnetic Resonance monitoring of the corresponding syntheses has permitted to determine the optimal metal/ligand ratio for leading to small and well-dispersed nanoparticles. Exchange ligand reactions of the as-prepared materials have proven the strong interaction of the phosphines with the metal surface; only oxidative treatment using hydrogen peroxide could release the phosphine-based stabiliser from the metal surface. Pd and Ru nanoparticles have been evaluated in hydrogenation reactions, confirming the robustness of the stabilisers, which selectively permitted the hydrogenation of exocyclic C=C bonds, preventing the coordination of the aromatic rings and as a result, their hydrogenation.

  8. Preconditioning of Nonlinear Mixed Effects Models for Stabilisation of Variance-Covariance Matrix Computations.

    Aoki, Yasunori; Nordgren, Rikard; Hooker, Andrew C


    As the importance of pharmacometric analysis increases, more and more complex mathematical models are introduced and computational error resulting from computational instability starts to become a bottleneck in the analysis. We propose a preconditioning method for non-linear mixed effects models used in pharmacometric analyses to stabilise the computation of the variance-covariance matrix. Roughly speaking, the method reparameterises the model with a linear combination of the original model parameters so that the Hessian matrix of the likelihood of the reparameterised model becomes close to an identity matrix. This approach will reduce the influence of computational error, for example rounding error, to the final computational result. We present numerical experiments demonstrating that the stabilisation of the computation using the proposed method can recover failed variance-covariance matrix computations, and reveal non-identifiability of the model parameters.

  9. The influence of preliminary aerobic treatment on the efficacy of waste stabilisation under leachate recirculation conditions

    Monika Suchowska-Kisielewicz


    Full Text Available This article presents the changes in the chemical composition of leachate and the concentrations and quantity of methane production in each individual decomposition phases, determined for untreated and after aerobic treatment of waste stabilised in anaerobic reactors with and without leachate recirculation. The research results demonstrate that leachate recirculation intensifies the decomposition of both aerobically treated and untreated waste. The methane production in the reactor with untreated, stabilised waste with recirculation was 28% higher; and in the reactor with aerobically treated waste, the methane production was 24% higher than in the reactors without recirculation. An important finding of the study is that aerobic treatment of waste prior to landfilling effectively reduces the quantity of pollutant emissions in leachate and biogas from waste and increases the availability for methane micro-organisms of organic substrates from difficult-to-decompose organic substances.

    Benabdallah, Amel; Echi, Nadhem


    This paper deals with the state and output feedback stabilisation problems for a family of nonlinear time-delay systems satisfying some relaxed triangular-type condition. The delay is supposed to be constant. Parameter-dependent control laws are used to compensate for the nonlinearities. Based on the Lyapunov-Krasovskii functionals, global exponential stability of the closed-loop systems is achieved. Finally, an extension to nonlinear time-varying delay systems is given.

    B C Jha; K Patralekh; R Singh


    A simple method for computing decentralised stabilising controllers for a class of large-scale (interconnected) linear systems has been developed. Decentralised controls are optimal controls at subsystem level and are generated from the solution of algebraic Riccati equations for decoupled subsystems resulting from a new aggregation-decomposition technique. The method has been illustrated through a numerical example of a large-scale linear system consisting of three subsystems each of the fourth order.

  2. Loess and loess-like sediments from the foothills of the Banat Mountains, Romania - Examples from loess sections and Paleolithic sites

    Lehmkuhl, F.; Kels, H.; Hambach, U.; Protze, J.; Eckmeier, E.; Hilgers, A.; Klasen, N.


    New investigations from loess and loess-like sediments in the Western Plain of Romania provide evidences for a deeper insight and connection between long loess sections of the lowlands (Semlac) and short sections from the Carpathian foothills (Romanesti and Cosava). While the long loess sections provide evidence concerning climatic and environmental change since the middle Pleistocene the short sequences from the foothills include Paleolithic sites give information especially for the interstadial of the last glacial cycle when the first modern humans arrived in Europe. The section at Semlac is regarded as a key section for Western Romania, which offers possibilities to a) improve the understanding of the type and composition of the lowland loess sequences, b) to reconstruct the local loess-palaeosol succession and c) to connect the loesses of the region for the first time to loess-sequences in adjacent areas. The Paleolithic sites Romanesti and Cosava are situated at the foothills of the Banat Mountains in Romania and provide an important testament of life of the first European modern humans (Homo sapiens sapiens) during Middle Pleniglacial. Even though these sites have been extensively excavated, little is known about the site formation of related loess-like sediments and soils. First luminescence data for the region of all these investigated sections confirm sediments from the penultimate glacial period up to the Holocene. For Semlac, a first relative dating is given by rock magnetic methods in comparison to Serbian loess sections.

  7. Dynamics of Air Passenger Transportation in Eastern Romania

    Dan Păuna


    Full Text Available The concept of an air route mile is, of course, entirely different from that of a road or rail route mile. An air route is a direct service between two cities. The too-rapid development of the air route system must inevitably result in an average intensity of operations on the route, and this means the frequencies are low or high, or the airplanes used are profitable or unprofitable. The purpose of this paper is to emphasize air passenger dynamics in Romania and to calculate specific indicators regarding this calculation for the airports in eastern Romania in 2011t., this, because the air passenger featurea indicator passenger – kilometer, starting with 2009 no longer calculate for aviation and shipping.

    Full Text Available The decision-making process of consumers buying organic food is affected by several factors. Because of organic agriculture in Romania is growing, the objective of this paper was to analyze consumer opinions and preferences concerning organic food products in Romania. The survey involved 350 respondents. The respondents were divided into two groups using the Hierarchical multiple factor analysis (HMFA. The strongest reason for buying organic food for Romanian respondents is health care, presented by 42% of respondents. Respondents prefer to buy organic foods directly from the producers, followed by supermarkets, specialized shops and pharmacies. The prevailing price of monthly purchase of organic food is 10 to 20€. The respondents are able to pay for organic food from 5 to 10% more than for conventional food.

  12. Theoretical considerations about implementation of IAS 41 in Romania

    Liliana FELEAGĂ


    Full Text Available Although agriculture is an important part of the world economy, accounting in agriculture still has many shortcomings. The adoption of IAS 41 „Agricuture” has tried to improve this situation and increase the comparability of financial statements of entities in the agricultural sector. Although controversial, IAS 41 is the first step of a consistent transition to fair value assessment in the agricultural sector. The objective of our work is the analysis of IAS 41 and current accounting agricultural situation in Romania. Accounting regulations in Romania are in accordance with European directives and, in many respects, converged with IFRS referential. Provisions of IAS 41, however, are not reflected directly in Romanian regulations. With the increase of forest land transactions and foreign investments in animal farms, it is expected that recognition and measurement of biological assets under IAS 41 to become a necessity.

    Full Text Available The paper aimed to present the evolution of supply demand and of wheat in Romanian market. It is based on the statistical data provided by National Institute of Statistics and European Statistics (Eurostat. The data have been processed into the following indicators: cultivated surfaces, obtained production, consumption per capita. Wheat production is correlated with seeding surface, but, sometimes paradoxes appear, where even if the cultivated surface is large the production is low. During the analyzed period, cultivated surfaces remained constantly; the production has continuously increased, so that in the year 2013 there are 7,383 million tonnes of wheat in Romania. As a conclusion, Romania is able to support domestic demand for wheat and can also export a significant amount of this grain.
