    Full Text Available The aim of this work is to investigate how the spatial variability of soil properties and soil erodibility (K factor were affected by the changes in land use allowed by irrigation with water from a reservoir in a semiarid area. To this, three areas representative of different land uses (agroforestry grassland, Lucerne crop and olive orchard were studied within a 900 ha farm. The interrelationships between variables were analyzed by multivariate techniques and extrapolated using geostatistics. The results confirmed differences between land uses for all properties analyzed, which was explained mainly by the existence of diverse management practices (tillage, fertilization and irrigation, vegetation cover and local soil characteristics. Soil organic matter, clay and nitrogen content decreased significantly, while K factor increased with intensive cultivation. The HJ-biplot methodology was used to represent the variation of soil erodibility properties grouped in land uses. Native grassland was the least correlated with the other land uses. K factor demonstrated high correlation mainly with very fine sand and silt. The maps produced with geostatistics were crucial to understand the current spatial variability in the Alqueva region. Facing the intensification of land-use conversion, a sustainable management is needed to introduce protective measures to control soil erosion.

    Periodic profiles of spectral downwelling irradiance were performed at Alqueva reservoir, southeast of Portugal, with a new apparatus developed by the team. The device presents a hemispherical tip (180° of FOV) allowing measurements to be independent of solar zenith angle. It is coupled to a portable spectroradiometer through a fiber bundle driven by a customized frame for protection and to keep the tip pointing to the zenith direction in underwater environment. The profiles obtained can be used to estimate the spectral and broadband light attenuation coefficients in the water column. The attenuation coefficients are relevant for the water surface layer energy budget, in particular, this coefficient is important in the computation of the water surface temperature, which is a key parameter for heat and moisture transfers between the reservoirs and the atmosphere, namely by the lake models. A comparison measurement was performed with this new apparatus (180° of FOV) and the previous device (22° of FOV) in order to demonstrate the importance of using the hemispherical radiance. The comparison show resembling results between both devices, however the previous device tends to underestimate the attenuation coefficient and increase the degree of uncertainty.

    Microcystins (MCs) are toxins produced by cyanobacteria which are common organisms in the phytoplankton of eutrophic lakes, rivers and freshwater reservoirs. In the present work, a novel method of liquid chromatography-electrospray ion trap tandem mass spectrometry (LC/ESI/Ion trap-MS/MS), operated in the negative ionization mode, was developed for the analysis of these cyanotoxins. The method was applied to determine the amounts of total microcystins-LR, -YR and -RR in two water reservoirs in Southern Portugal, namely Alqueva and Beliche. A total of 30 water samples were analysed along 2011. Solid phase extraction (SPE) was used for sample cleaning-up and analyte enrichment. The extracted toxins were separated on a C18 column with a gradient of acetonitrile/water with 0.1% formic acid. Detection of microcystins was carried out using multiple reaction monitoring (MRM) in the negative polarity mode, as this method gave a higher selectivity. The MC-RR, YR and LR quantification limits were 17.9, 31.7 and 15.8 ng/L, respectively; quite below the limits recommended by WHO guidelines for drinking water (1 μg/L). Total MC highest concentrations were found in the warm months of June, July and September in Alqueva sampling sites, with concentrations of MC LR and RR ranging 17-344 and 25-212 ng/L, respectively, showing comparable results for MC-RR and LR and slightly lower concentration of MC-YR. Detected values for Beliche reservoir were below quantification limits.

    Full Text Available The study aims to determine how the knowledge obtained from the study of prehistoric heritage found during the construction of the Alqueva dam and irrigation system (Portugal can enhance the current tourist experience of the destination. A new approach is necessary given the inaccessibility of the archeological remains, thus creative tourims and experience economy frame the theoretical basis of this paper. Semi-directed interviews were carried out to 35 tourism stakeholders in order to assess their view of the regional tourism experience, their interest in ex-situ and virtual products based on the archeological knowledge and how these may add to the Alqueva destination. Findings show that stakeholders are still firmly attached to the conventional approach to archaeology but that, even though unaware of the archaeological findings, they believe that they could benefit form the introduction of creative products as a way of complementing the current offer.

    Portugal's 1983 population of 10.04 million was growing at .7%/year. 97% were Roman Catholic, 80% were literate, and 4.1 million were in the labor force in 1984. Portugal is mountainous north of the Tagus River and consists of rolling plains in the central south. The Azores and Madeira islands belong to Portugal but enjoy considerable autonomy. Portugal's dependency of Macau on the Chinese coast is an autonomous entity under Portuguese administration. The former teritories of Goa and Portuguese Timor were annexed by India and Indonesia respectively in 1961 and 1976, and the former territories in Africa achieved independence in 1974 and 1975. Portugal, 1 of the oldest states in Europe, traces its modern history to A.D. 1140 when the 1st king was crowned. The approximate present day boundaries were secured in 1249. Portugal eventually became a massive colonial empire with territories in Africa and Latin America and outposts in the Far East. The Portuguese Republic replaced the monarchy in 1910. After some years of instability, Antonio Salazar became prime minister, and with his successor, ruled Portugal as an authoritarian "corporate" state for 42 years. An almost bloodless coup in 1974 led to establishment of a parliamentary democracy. The 4 main organs of national government are the presidency, the prime minister and council of ministers, the assembly of the republic, and the courts. Portugal's gross domestic product (GDP) in 1984 was $19.4 billion, and per capita income was $1930. After almost a decade of rapid growth, the economy declined in the mid 1970s due to disruption after the 1974 revolution and the large influx of refugees from Portugal's former colonies in Africa. Growth resumed in the late 1970s, but structural problems and an often adverse international economic climate have slowed progress. The proportion of the labor force in agriculture has dropped from 42% to 24.4% since 1960. Agricultural production now contributes only 8.8% to the GDP, and a

    Montargil reservoir, located in a dry flat area in the centre of Portugal, was filled in 1958 to fulfil agricultural, electric and industrial requirements. In May 1996, an intensive bloom of phytoplankton was detected. The algal community was strongly dominated by cyanobacteria with predominance of Aphanizomenon flos-aquae from May to June and Microcystis aeruginosa from July to August. Extracts of samples collected during the bloom period showed high toxicity by mouse bioassay. During the M. aeruginosa predominance period, the toxicity was ascribed to the presence of hepatotoxins, but clear symptoms of paralytic shellfish poison were observed when A. flos-aquae was the dominant species. In order to confirm the production of neurotoxins a strain of A. flos-aquae was isolated and established in culture. In this manuscript, we show the morphological characteristics and confirm paralytic shellfish toxins production by the strain isolated and maintained in culture. Identification of the saxitoxin analogs was achieved using high performance liquid chromatography with postcolumn fluorescence derivatization (HPLC-FLD) and liquid chromatographic mass spectrometry technique (LC-MS). The toxins found in the culture extract were GTX5 (64.5 mol%), neoSTX (23.0 mol%), dcSTX (6.1 mol%), STX (5.4 mol%) and GTX6 (1.1 mol%). This is, to our knowledge, the first report of unambiguous evidence of paralytic shellfish toxins produced by freshwater cyanobacteria in Portugal. The toxin profile is rather different from the previously reported PSP producing A. flos-aquae and demonstrates its diversity in terms of toxin production. PMID:10858510

    Climate change scenarios project warmer temperatures and less precipitation in Mediterranean watersheds. This can aggravate drought conditions, with negative impacts on water supply. Here, reservoirs may play an important role to mitigate these impacts. However, the implications of climate change are not always considered in the reservoir planning and management. This study aimed to address this issue for the Upper Sabor watershed, northeast Portugal. This is a medium watershed (403km2), part of the Sabor river, a tributary of Douro (one of the major rivers in the Iberian Peninsula). It is a mountainous watershed (up to 1500m), characterized by humid Mediterranean climate, with three dry months in summer. Almost 52% of the area is occupied by shrubland and 18% agriculture. Water supply for about 33 000 people has been based almost exclusively in one reservoir, but constant problems of water supply in dry summers, which coincide with a doubling of population due to summer holidays, led to the construction of a new reservoir in 2015. The Soil and Water Assessment Tool (SWAT) model was used for a climate change impact assessment, considering the current water supply regime (single reservoir) and the construction of the new reservoir. SWAT was calibrated and validated against daily-observed discharge and reservoir volume, with a good agreement between model predictions and observations. Results from four GCMs (General Circulation Models) for two scenarios (RCP 4.5 and RCP 8.5) were statistically downscaled and bias-corrected with ground observations; climate scenarios for 2021-2040 and 2041-2060 were compared with a control period in 1981-2000. In the future, a general increase of temperatures is expected in the Upper Sabor watershed, especially in the maximum temperature under RCP 8.5 scenario for 2041-2060 (Tmax: +2.88°C). The change in precipitation is more uncertain, with larger differences according to the selected climate model. Annual precipitation would

    Full Text Available The main purpose of this paper is to assess the impact of the 2003 Common Agricultural Policy and the Health-Check in Alqueva Irrigation project. This project will create 110 thousand hectares of irrigated land in the Alentejo region. The latest developments of Common Agricultural Policy in 2003 and 2009 and the Water Framework Directive guidelines could have negative impacts on the project competitiveness. The selection of representative farms was made using farmers' interviews and multivariate methods. A multi-period mathematical programming model was developed to assess the farms competitiveness. The results show that the Common Agricultural Policy and the Water Framework Directive will have negative effects on farms. This can be overcome by the adoption of new technologies and more sustainable agricultural systems ensuring the future competitiveness of irrigated farms.O objectivo deste estudo é avaliar os impactos da PAC de 2003 e do Health-Check na competitividade do regadio de Alqueva na região Alentejo no Sul de Portugal. O estudo foi realizado com base em três grupos de empresas agrícolas representativas seleccionadas de numa amostra de explorações agrícolas do Perímetro de Rega do Monte Novo. Para cada uma delas, foi desenvolvido um modelo de programação matemática multi-período adaptado às suas características específicas. Os principais resultados permitem concluir que a Política Agrícola Comum e a Directiva Quadro Água condicionam a competitividade do regadio nesta região. No entanto a adopção de novas tecnologias de produção permitirão contrariar esses efeitos negativos e assegurar a competitividade futura do regadio.

  18. Atmospheric electrical field measurements near a fresh water reservoir and the formation of the lake breeze

    Full Text Available In order to access the effect of the lakes in the atmospheric electrical field, measurements have been carried out near a large man-made lake in southern Portugal, the Alqueva reservoir, during the ALqueva hydro-meteorological EXperiment 2014. The purpose of these conjoint experiments was to study the impact of the Alqueva reservoir on the atmosphere, in particular on the local atmospheric electric environment by comparing measurements taken in the proximity of the lake. Two stations 10 km apart were used, as they were located up- and down-wind of the lake (Amieira and Parque Solar, respectively, in reference to the dominant northwestern wind direction. The up-wind station shows lower atmospheric electric potential gradient (PG values than the ones observed in the down-wind station between 12 and 20 UTC. The difference in the atmospheric electric PG between the up-wind and the down-wind station is ~30 V/m during the day. This differential occurs mainly during the development of a lake breeze, between 10 and 18 UTC, as a consequence of the surface temperature gradient between the surrounding land and the lake water. In the analysis presented, a correlation is found between the atmospheric electric PG differences and both wind speed and temperature gradients over the lake, thus supporting the influence of the lake breeze over the observed PG variation in the two stations. Two hypotheses are provided to explain this observation: (1 The air that flows from the lake into the land station is likely to increase the local electric conductivity through the removal of ground dust and the transport of cleaner air from higher altitudes with significant light ion concentrations. With such an increase in conductivity, it is expected to see a reduction of the atmospheric electric PG; (2 the resulting air flow over the land station carries negative ions formed by wave splashing in the lake's water surface, as a result of the so-called balloelectric effect

Isolates resistant to sulfonamides and/or streptomycin, gentamicin and trimethoprim were screened (PCR, sequencing for sul genes (sul1, sul2, sul3 and class 1 and 2 integrons. Presence of ESBLs was inferred using the DDST and further confirmed by PCR and sequencing. ESBL producers were selected for clonal analysis, plasmid characterization and conjugation assays by standard methods. ESBL-producing isolates were found in 1.8% (2/113 of samples, corresponding to Escherichia coli of phylogroups A (n=1 and B1 (n=1 carrying transferable blaCTX-M-14 and the new blaTEM-153, respectively. A 80kb IncK-blaCTX-M-14 was found, being highly related to that widely spread among CTX-M-14 producers of humans and animals from Portugal and other European countries. sul genes were found in 88% (22/25;sul2-60%, sul1-48%, sul3-4% of the sulfonamide resistant isolates. Class 1 integrons were more frequently found than class 2 (7% vs 3%. Interestingly, gene cassette arrangements within these platforms were identical to those commonly observed among Enterobacteriaceae from Portuguese food-producing animals, although aadA13 is here firstly described in Morganella morganii. These results reinforce the relevance of human commensal flora as reservoir of clinically relevant antibiotic resistance genes including blaESBLs, and highly transferable genetic platforms as IncK epidemic

    Birds are important in the ecology of Borrelia burgdorferi sensu lato (s.l.) because they are important hosts for vector tick immature stages and are known reservoirs for some Borrelia genospecies. The aim of our study was to assess the role of common passerine bird species as reservoirs for B. burgdorferi s.l. in Western Europe. We surveyed birds in enzootic areas in Portugal, where no information is available for birds as reservoirs for this aetiologic agent and where B. lusitaniae, for which few reservoirs have been identified, is the dominant genospecies. Twenty-three birds (2.9%), including Turdus merula, T. philomelos, Parus major and Fringilla coelebs harboured infected ticks, but only Turdus sp. harboured infected tick larvae. In one study area, although B. lusitaniae was dominant in questing Ixodes ricinus, no ticks feeding on birds were infected with this genospecies, and B. valaisiana was the dominant genospecies in I. ricinus larvae feeding on birds. In the other area ticks collected from birds were mainly I. frontalis which were infected with B. turdi. Two skin biopsies (4.2%) from two T. merula were positive, one for B. valaisiana and the other for B. turdi. This is the first report for B. turdi in Western Europe.

    Climate change (CC) scenarios for the Mediterranean region include an increase in the frequency and intensity of extreme weather events such as drought periods. higher average temperatures and evapotranspiration, combined with the decrease of annual precipitation may strongly affect the sustainability of water resources. In face of these risks, improving water management actions? by anticipating necessary operational measures is required to insure water quantity and quality according to the needs of the populations and irrigation in agriculture. This is clearly the case of the Alentejo region, southern Portugal, where present climatic conditions already pose significant challenges to water resources stakeholders, mainly from the agricultural and the urban supply sectors. With this in mind, the GestAqua.AdaPT project is underway during 2015 and 2016, aiming at analyzing CC impacts until 2100 and develop operational procedures to ensure water needs are adequately satisfied in the Monte Novo and Vigia reservoirs, which supply water for the city of Évora and nearby irrigation systems. Specific project objectives include: a) defining management and operational adaptation strategies aiming to ensure resource sustainability, both quantitatively and qualitatively; b) evaluate future potential costs and available alternatives to the regional water transfer infrastructure linked with the large Alqueva reservoir implemented in 2011; c) defining CC adaptation strategies to reduce irrigation water needs and d) identification of CC adaptation strategies which can be suitable also to other similar water supply systems. The methodology is centered on the implementation of a cascade of modeling tools, allowing the integrated simulation of the multiple variables under analysis. The project is based on CC scenarios resulting from the CORDEX project for 10 combinations of Global and regional climate models (GCMs and RCMs). The study follows by using two of these combinations

    The water resources sector is one of the most vulnerable to climate change. In southern Europe, an increase of water scarcity is expected, combined with a higher frequency and length of severe droughts. Water management in these regions is already a challenge, and several severe droughts occurred there during the last decades, such as the severe droughts of 2005 and 2012 in Portugal, which have highlighted existing vulnerabilities and led to the disruption of part of water supplies. Furthermore, the evolution of socio-economic conditions and even climate change could cause changes to population and land-uses, with the potential to increase pressures on existing resources. The threat of scarcer water resources highlights the need to understand these vulnerabilities and act to reduce them, adapting to the impacts of future climate and land use changes. In fact, water resources governance has been pointed as a key challenge in the present and in the future, as it builds capacity on how to deal with stress and uncertainties generated by climatic variability and global change. Project ERLAND is focused on assessing the eco-hydrological impacts of climate change in Portugal, and therefore water scarcity and droughts are an important focal point on this research. One of the study areas is the Xarrama river basin in southern Portugal, which feeds the multi-purpose Vale do Gaio reservoir used for irrigation and urban water supplies, coupled with a small hydroelectric generating capacity. Currently it experiences some water quality problems and there is already the need of water transfers from other reservoirs to maintain supplies and quality. This is combined with ongoing land-use changes, where irrigated vineyards and olive groves have started to replace traditional rainfed pastures and cereal cultivation. The exposition and vulnerability of the Xarrama basin and the Vale do Gaio reservoir is being addressed for present and future conditions. Future climate scenarios were

    Artificial light at night (ALAN), producing light pollution (LP), is not a matter restricted to astronomy anymore. Light is part of modern societies and, as a consequence, the natural cycle day-night (bright-dark) has been interrupted in a large segment of the global population. There is increasing evidence that exposure to certain types of light at night and beyond threshold levels may produce hazardous effects to humans and the environment. The concept of "dark skies reserves" is a step forward in order to preserve the night sky and a means of enhancing public awareness of the problem of spread of light pollution worldwide. The aim of this study was to assess the skyglow at two sites in Portugal, the Peneda-Gerês National Park (PNPG) and the region now known as Dark Sky Alqueva Reserve. The latter site was classified as a "Starlight Tourism Destination" by the Starlight Foundation (the first in the world to achieve this classification) following a series of night sky measurements in situ described herein. The measurements at PNPG also contributed to the new set of regulations concerning light pollution at this national park. This study presents the first in situ systematic measurements of night sky brightness, showing that at the two sites the skies are mostly in levels 3 to 4 of the Bortle 9-level scale (with level 1 being the best achievable). The results indicate that the sources of light pollution and skyglow can be attributed predominantly to contamination from nearby urban regions.

  17. Women in Portugal.

    Science.gov (United States)

    Barbosa, M

    1981-01-01

    Prior to 1974, women in Portugal were restricted by the Penal Code and had little organizational power. Women's groups were formed within the Catholic Church to teach women about cooking, child care, and home economics. There was no contact with international women's groups. The press only reported events such as bra burning. 80% of all illiterates in Portugal are women. The conditions of Portuguese women are described after the revolution of April 25, 1974. Present roles are discussed for work, health, education, religion, trade unions and political parties, and women's organizations. The Women's Liberation Movement (WLM) appeared in May 1974 among a heterogenous group of women in Lisbon who were concerned about the oppression of women. WLM made feminist issues public amid ridicule and promoted the declaration of equal rights for women in the 1976 Republic Constitution and in the Family Code. Wage discrimination became illegal in 1979. Women represent 32.8% of the labor force. Unemployment is particularly high among women and is increasing. Women's wages and levels of skill are the lowest. The Christian Democratic government is actively engaged in a campaign to keep women at home and has formed the special Ministry of Family Affairs, which encourages large families and women's home activity in order to save jobs for men. There is a crisis in education: large class sizes and limited number of schools. Child care for the working mother is expensive when available and rarely available. An obstacle to women's rights has been the role of the Catholic Church, which fought equal rights legislation, condemned the Family Code and divorce laws, forbade the practice of contraception, and supported the movement against abortion. Only 1 member of government is a women, and she is considered a token. Trade unions have a women's section, but little attention is given to the problems of women. Women's groups within larger organizations have little autonomy. Those with autonomy

  8. Geology and religion in Portugal

    Carneiro, Ana; Simoes, Ana; Diogo, Maria Paula; Mota, Teresa Salomé

    2013-01-01

    This paper addresses the relationship between geology and religion in Portugal by focusing on three case studies of naturalists who produced original research and lived in different historical periods, from the eighteenth to the twentieth century. Whereas in non-peripheral European countries religious themes and even controversies between science and religion were dealt with by scientists and discussed in scientific communities, in Portugal the absence of a debate between science and religion within scientific and intellectual circles is particularly striking. From the historiographic point of view, in a country such as Portugal, where Roman Catholicism is part of the religious and cultural tradition, the influence of religion in all aspects of life has been either taken for granted by those less familiar with the national context or dismissed by local intellectuals, who do not see it as relevant to science. The situation is more complex than these dichotomies, rendering the study of this question particularly appealing from the historiographic point of view, geology being by its very nature a well-suited point from which to approach the theme. We argue that there is a long tradition of independence between science and religion, agnosticism and even atheism among local elites. Especially from the eighteenth century onwards, they are usually portrayed as enlightened minds who struggled against religious and political obscurantism. Religion—or, to be more precise, the Roman Catholic Church and its institutions—was usually identified with backwardness, whereas science was seen as the path to progress; consequently men of science usually dissociated their scientific production from religious belief.

    Full Text Available This article is a reflection upon the exercising of transnational citizenship as a consequence of international migration, applied to Latin Americans resident in Portugal. In order to do this we have adopted the concept of transnational citizenship, as its malleability allows us to consider the whole concept of countries of origin and destination and the influence of bilateral and international relations. We ask how transnational citizenship is exercised in the European Union, Ibero-American and, particularly, Portuguese spaces, and whether it is affected by the economic crisis in Europe and, in particular, Portugal, by analysing the cases of Argentines, Brazilians and Uruguayans living in Portugal.

    The prevalence of carbon monoxide intoxication in the World shows that this is a common situation. In Portugal, there are no concrete data available in literature and its incidence remains unknown. Currently, the use of hyperbaric oxygen is a valid therapeutic for carbon monoxide poisoning management. However, its effectiveness and its proper handling are still controversial. The first aim of this study was to estimate the incidence of carbon monoxide intoxication in Portugal and to analyze its demographic characteristics. The second objective of this work was to evaluate the possible change in the type of treatment applied in areas near de hyperbaric chamber of Unidade Local de Saúde de Matosinhos, since its opening in June 2006. To achieve these objectives, we conducted a survey on admissions data for carbon monoxide intoxication occured between January first, 2000 and December 31, 2007. These data was collected in seven hospitals and in the Administração Central do Sistema de Saúde, I.P. Nationally, 621 hospitalizations were recorded, which represents an incidence of 5,86/100000 in 8 years. In the seven hospitals, there were 93 hospitalizations due to carbon monoxide intoxication during the same period of time. There was a peak of incidence during winter, between November and March and there was a similar distribution in men (47,3%) and women (52,7%). Since June 2006, date of opening of the hyperbaric chamber, the Unidade Local de Saúde de Matosinhos, E.P.E. recorded a sharp increase in the number of hospitalization for carbon monoxide intoxication. The number of admissions in the 19 months after the chamber opening was double the number of all cases occurred in that institution in the 65 months prior. We concluded that, in Portugal, carbon monoxide intoxication is an uncommon situation but it´s still an important cause of hospitalization.

    In a way to reduce the external energy dependence, increasing also the investments in renewable energy sources and aiming for the concretization of the European renewable objectives, the Portuguese government defined a goal of 5100 MW of installed wind power, up to 2012. If the drawn objectives are accomplished, by 2010 the wind power share may reach values comparable to leading countries like Denmark, Germany or Spain. The Portuguese forecasts also indicate a reinforcement of the natural gas fired generation in particular through the use of the combined cycle technology, following the European tendency. This analysis sets out to evaluate the total generating cost of wind power and CCGT in Portugal. A life cycle cost analysis was conducted, including investment costs, O and M costs, fuel costs and external costs of emissions, for each type of technology. For the evaluation of the externalities ExternE values were used. The results show that presently the wind power production cost is higher than the CCGT one, at least from the strictly financial point of view. CCGT costs increase significantly when charges for externalities are included. However, they only reach levels higher than the equivalents for wind power for high externality costs estimations. This partially results from the low load factor of the wind farms in Portugal and also from the low emission levels of the gas fired technology used in the comparison. A sensitive analysis of the technical and economical parameters was also conducted. Particular attention was given to the natural gas prices due to the possible increase over time. The fuel escalation rate is the parameter that has larger effects on the final costs. It was verified that the total cost of wind plant is more influenced by the load factor than the total cost of CCGT. (au)

  5. Muslim Slaves and Freedmen in Medieval Portugal

    Directory of Open Access Journals (Sweden)

    Soyer, François

    2007-12-01

    Full Text Available The study of slavery in medieval Portugal has focused almost exclusively on the status and fate of the sub-Saharan Africans who started to arrive in the kingdom from 1441 onwards. The work of A. C. de C. M Saunders, A Social History of Black Slaves and Freedmen in Portugal 1441-1555 (Cambridge University Press, 1982 has been particularly important in this respect. In stark contrast to this, the fate of the substantial number of Muslim slaves who lived and worked in Portugal during the medieval period has to a large extent been overlooked. Using documentary evidence obtained from the national Portuguese archives, this article proposes to analyse in detail the origins of these slaves, their economic and social role and the laws that were promulgated to control them and their owners. The status of freedmen and manumission practices are also closely studied.

    El estudio de la esclavitud en el Portugal medieval ha sido dominado por estudios sobre los esclavos oriundos del África subsahariana que comenzaron a ser importados en aquel reino desde 1441. La obra de A. C. de C. M. Saunders, A Social History of Black Slaves and Freedmen in Portugal 1441-1555 (Cambridge University Press, 1982 ha sido particularmente importante a este respecto. En contraste con esta situación, se sabe relativamente poco de los esclavos musulmanes en el reino medieval de Portugal. Utilizando nuevas fuentes documentales del archivo nacional portugués, este artículo se propone examinar los orígenes de estos esclavos musulmanes y su posición económica y social en el Portugal del medievo, así como las leyes reales que fueron promulgadas para controlar a los esclavos y a sus dueños. La posición social de los libertos y las prácticas de manumisión serán también estudiadas.

    Darwinism was championed in Portugal by the University and progressionist political parties from the 1860's on. Neo-Darwinism was neglected in its proper time and so the acceptance of the inheritance of acquired characters continued over the first decades of the 20th century. Men of medical education who were professors of Biology at the University of Oporto supported neo-Lamarckian theories in early 20th century. The first one has been Américo Pires de Lima (1886-1966, professor of Botany, whose doctoral dissertation sustaining early Darwinism and neo-Lamarckism was presented in 1912. This thesis, as well as a few neo-Lamarckian publications with antropological significance, are commented and discussed in the present paper.



    El Darwinismo fue defendido en Portugal en la Universidad y por los partidos políticos progresistas durante la década de los años 60 del siglo XIX.

  9. In Portugal, the energy revolution is underway

    International Nuclear Information System (INIS)

    As at the beginning of 2013, 70 per cent of the electricity consumed in Portugal had a renewable origin, this article outlines that this result is based on a strong-willed policy. In fact, Portugal entered the energy transition in 2001 with its '4E program' (energy efficiency and endogenous energies) which aimed at reaching 60 per cent of renewable energies in electricity consumption by 2020. This program was based on a strong development of wind and hydraulic energy. Moreover, the country developed its own capacities for the manufacturing of wind turbines. On another hand, other renewable energies (notably solar energy) seem a bit late although several projects are underway. As far as hydraulic energy, a dam project is a matter of controversy

    Several studies demonstrate that wildfires in Portugal present high temporal and spatial variability as well as cluster behavior (Pereira et al., 2005, 2011). This study aims to contribute to the characterization of the fire regime in Portugal with the multivariate statistical analysis of the time series of number of fires and area burned in Portugal during the 1980 - 2009 period. The data used in the analysis is an extended version of the Rural Fire Portuguese Database (PRFD) (Pereira et al, 2011), provided by the National Forest Authority (Autoridade Florestal Nacional, AFN), the Portuguese Forest Service, which includes information for more than 500,000 fire records. There are many multiple advanced techniques for examining the relationships among multiple time series at the same time (e.g., canonical correlation analysis, principal components analysis, factor analysis, path analysis, multiple analyses of variance, clustering systems). This study compares and discusses the results obtained with these different techniques.

    The tick-borne protozoan parasite Theileria annulata causes tropical theileriosis, a severe disease of cattle that occurs across the Mediterranean littoral, the Middle East and Southern Asia. In the Mediterranean region, the disease has long been perceived as being a constraint to livestock production in North Africa and Turkey but was believed to have minimal impact in Southern European countries. It has recently been demonstrated that in Southern Portugal the prevalence of T. annulata is approximately 30%. While the population genetics of the parasite and the multiplicity of infection in the bovine host have been studied in a number of countries, no information is currently available on the composition of the parasite population in Southern Europe or its relationship to populations in bordering regions. A parasite genotyping system, based on micro- and mini-satellite amplification, was used to perform genetic analysis of T. annulata populations from T. annulata infected cattle in twelve farms in Southern Portugal. A diversity of genotypes and a high multiplicity of infection were found, suggesting that the parasite possesses a panmictic population in this region. In comparison with genotypes found in Tunisia and Turkey, parasites from Portugal form a genetically distinct group and show lower genetic diversity. PMID:27109468

All the terrestrial isopods from caves of mainland Portugal, including data from the literature and new material, are listed, revealing new biodiversity patterns. Twenty-seven species, belonging to 15 genera and six families, are known, of which 16 species are considered to be exclusively from subterranean ecosystems, i.e., troglobionts. Trichoniscidae is the most diverse family. Seven species in the family Trichoniscidae and one species in the family Styloniscidae are described as new (all with Reboleira & Taiti as authors: Trichoniscoides bellesi sp. nov. from the Montejunto Massif; T. sicoensis sp. nov. from the Sicó Massif; Metatrichoniscoides salirensis sp. nov. from the typhonic valley of Caldas da Rainha; Troglonethes olissipoensis sp. nov. from the Lisbon Peninsula; T. arrabidaensis sp. nov. from the Arrábida Massif; Miktoniscus longispina sp. nov. from the Sicó Massif and Cesaredas Plateau; Moserius inexpectatus sp. nov. from the Estremenho Massif; and Cordioniscus lusitanicus sp. nov. from Alentejo and Algarve, the southernmost provinces of Portugal.

    Full Text Available ABSTRACT: Considering the available data, the Mousterian period is the only techno-complex from the Middle Paleolithic identified and characterized in Portugal. However, some of the sites referred in this work should be simply attributed to the Middle Paleolithic due to the lack of detailed elements. The site of Vale do Forno 8 probably represents the transition between the final Upper Paleolithic and the early Middle Paleolithic.The open-air sites such as the ones in the outskirts of Lisbon and on the left margin of the Tagus estuary, where vestiges are extremely abundant and the permanence for long periods correspond to sites of residential character.None of these sites were subject to extensive excavations in order to confirm this type of settlement and further knowledge of the social organization of the inhabited spaces. Other open-air sites located in fluvial terraces present smaller areas of occupation and were probably related to game activities, maybe seasonal in nature. This was the case of Santo Antão do Tojal, were elephants and horses were eventually captured, of Foz do Enxarrique were red deer was almost exclusive and of Vilas Ruivas, were faunal remains were not preserved but remains of wind-breaks or hunting blind structures were found associated with fireplaces and post-holes. Fireplaces were also found in Gruta da Buraca Escura and on the open-air site of Santa Cita.Caves such as Gruta da Oliveira and the Gruta Nova da Columbeira show long stratigraphic sequences and prolonged settlements, of residential type, though a few other caves also show temporary settlements related to game activities or the exploitation of geological resources. In most cases, there is an alternance of the cave occupation by humans and large carnivores. Food subsistence of humans was non-specialized, capturing large, mid and also small preys such as the rabbit, an abundant endemic species. The terrestrial turtle was also captured, especially in Gruta

    2014-09-01

    In sum, this paper examines the core determinants of lottery sales in Portugal. With panel data analysis covering 18 Portuguese districts and 5 years, this study explains the variations in a district's per-capita lottery sales in terms of key theoretical hypotheses such as per capita district income, age, education index, gender and religion. This paper concludes that the richer Portuguese districts spend more than the poorer districts and there is an inverted-U relationship between lottery sales and per capita income. The paper also concludes that married Catholic citizens spend more on lottery products than others and that the level of education returns a negative effect on lottery spending.

    This radar image of Lisbon, Portugal illustrates the different land use patterns that are present in coastal Portugal. Lisbon, the national capital, lies on the north bank of the Rio Tejo where the river enters the Atlantic Ocean. The city center appears as the bright area in the center of the image. The green area west of the city center is a large city park called the Parque Florestal de Monsanto. The Lisbon Airport is visible east of the city. The Rio Tejo forms a large bay just east of the city. Many agricultural fields are visible as a patchwork pattern east of the bay. Suburban housing can be seen on the southern bank of the river. Spanning the river is the Ponte 25 de Abril, a large suspension bridge similar in architecture to San Francisco's Golden Gate Bridge. The image was acquired on April 19, 1994 and is centered at 38.8 degrees north latitude, 9.2 degrees west longitude. North is towards the upper right. The image is 50 kilometers by 30 kilometers (31 miles by 19 miles).

    Full Text Available In Portugal we are assisting, since the nineties, to the reform of all public accounting, having as main innovations the utilization of double entry system and the obligatoryness to implement three accounting systems: budget accounting, patrimonial and cost accounting. In the systems of patrimonial and cost accounting, it will be used the accrual systems. The publication of the first Public Accounting Plan (POCP in 1997 identifies the change from a traditional public accounting, which main objective was the execution and budgetary control to a modern public accounting with economical, financial and patrimonial information that serves as basis to the decision making and to the evaluation of public entities concerning the efficient, effective utilization and economy of the public resources, contributing, this way, to the implementation of the New Public Management. The objective of this work has two perspectives: to describe and analyze the situation in Portugal concerning the public accounting reform and to present some results consequent to twelve years of implementation.

  1. CHINESE ENTREPRENEURIAL ACTIVITY IN PORTUGAL: TRADITIONAL ETHNIC STRATEGIES?

    Directory of Open Access Journals (Sweden)

    2010-12-01

    Full Text Available In Portugal in recent decades, just like in other welcoming countries, immigrants have reached levels of entrepreneurial activity that are higher than those of autochthonous citizens. However, a deeper analysis of the official data shows that not all immigrant groups have the same tendency to become entrepreneurs. In this respect, the Chinese stand out as being the group with the highest ratio of entrepreneurial activity in Portugal, despite the fact that their migration is a relatively recent phenomenon. What factors can explain the Chinese community’s disproportionate rate of entrepreneurial initiative? Do they possess any particular resources that make them more enterprising than the autochthonous population, or than other groups of immigrants? Does the context of Portugal hamper certain opportunities or in some way limit their economic integration into the job market? Do we find similar business strategies among other Chinese entrepreneurs residing in welcoming societies apart from that of Portugal? Why did Chinese business initiative grow at such an exceptional rate in Portugal in the late 1990s? By seeking answers to these questions, this article attempts to examine Chinese business strategies in Portugal, as well as their exceptional success rate in comparison with other entrepreneurial immigrants. To that end, the author has analysed the data gathered in a survey carried out on 309 Chinese entrepreneurs resident in Portugal (see Oliveira, 2005.

    Full Text Available From 1564 to 1565, Clusius (1526-1609 travelled to the Iberican Peninsula as the tutor of the young heir of the Függers. This journey, which lasted nearly a year, took the two men to the most important cities in the Peninsula. If strolling through the Portuguese countryside demonstrated the peculiarities of the local flora to the botanist, the decreed visit to Lisbon offered many surprising experiences. The encounter with the work recently arrived from the Orient —Colóquios dos Simples e Drogas he Cousas Mediçinais da Índia, by Garcia de Orta (Goa, 1563— awakened his interest. The present article weaves together considerations on the multiple impacts that the botanist’s voyage to Portugal caused in European science of the time.

  4. Occupational exposure in Portugal in 1999

    International Nuclear Information System (INIS)

    This study reports the occupational radiation doses for external exposure received in 1999 by the radiation workers monitored by the Radiological Protection and Nuclear Safety Department (DPRSN) in Portugal. Occupational exposures arise from conventional industry, research laboratories, the health or medical sector, and mining. There are no nuclear power plants in the country. There are two dosimetry systems running simultaneously at DPRSN, one based on film dosimetry and the other on thermoluminescence dosimetry (TLD). In 1999, 8400 persons were monitored, 3100 with film and 5300 with TLD and the data presented in this report were obtained by using both technologies. The annual mean effective doses received from external radiation in the different fields of activity and the distribution of the annual effective dose by dose intervals are presented. The collective annual dose by field of activity is estimated and the contribution to the total annual collective dose is determined. (author)

    Full Text Available Este artigo, baseado nalguns dos resultados de um projecto de investigação em curso, tem por objectivo analisar a difusão do emprego flexível em Portugal e mostrar a sua diversidade. A difusão de formas flexíveis de emprego insere-se nos processos de reestruturação produtiva e flexibilização do mercado de trabalho no contexto da intensificação da concorrência na economia global. Recorrendo a dados estatísticos procede-se a uma análise da difusão e da evolução de algumas das formas mais relevantes de emprego flexível em Portugal, tais como o trabalho com contratos de duração determinada, o trabalho temporário, o trabalho independente e o trabalho a tempo parcial. Os trabalhadores com emprego flexível têm níveis de satisfação bastante inferiores aos dos trabalhadores com emprego estável. No entanto, o emprego flexível não abrange situações de emprego homogéneas, mas situações muito diversificadas que são apresentadas através de uma tipologia de situações de emprego flexível e uma tipologia de trajectórias profissionais.

    2010-02-01

    Full Text Available España y Portugal son dos países que comparten mucho en el terreno de la historia, la cultura y la geografía. Sin embargo, esa misma proximidad se ha convertido muchas veces en el principal obstáculo para que cooperen entre sí.Desde la perspectiva portuguesa, la proximidad española se ha visto permanentemente como una amenaza a la independencia de Portugal. Desde el punto de vista de España, la cercanía de Portugal ha debilitado su consideración como país extranjero y ha acentuado un sentido de comunidad no siempre bien recibido por los portugueses. De modo que Portugal siempre ha querido diferenciarse y España ha respondido siempre aproximándose. Esta es la raíz del malentendido.Este cruce de percepciones distintas sobre el valor de proximidad, da lugar a todo tipo de equívocos, pues el deseo de diferenciación de uno puede entenderse como enemistad por el otro y, a la inversa, el de aproximación del segundo como invasión por el primero. Ejemplo de esto es lo que ocurre con la palabra iberismo, una palabra que se escribe igual en ambas lenguas pero que puede significar cosas opuestas, esto es, que puede ser un falso amigo. Así en las dos lenguas iberismo señala el ideal de una integración de ambos países, pero en portugués esto implica la subordinación de la soberanía portuguesa a la española y puede vincularse a la idea de traición; mientras que en español tiene una carga política mucho menor y puede apuntar a la simple simpatía por Portugal.En este artículo quiero mostrar cómo la proximidad de España y Portugal ha sido un obstáculo en las relaciones exteriores entre los dos países peninsulares, cuya comunicación ha sido distorsionada por los falsos amigos hasta el punto de convertirse, ellos mismos, en falsos amigos. Esto es, en países a los que se presupone una cercanía de propósitos que casi nunca se ve realizada en los hechos. Portugal and Spain are two countries that share history, culture and

    Climatic variability from the beginning of regular meteorological observations is now acknowledged. However, climate change prior to 1900 is far from being well known in Portugal, except for the 1675-1800 period in Southern Portugal. An interdisciplinary team is working in the frame of the KLIMHIST PROJECT ("Reconstruction and model simulations of past climate in Portugal using documentary and early instrumental sources, 17th-19th century)", since May 2012. The main objectives of the project are: (i) to contribute to the creation of a long-term history of climate in Portugal by producing databases of documentary evidence and of instrumental data since 1645, a period of natural climate variability that includes the Maunder Minimum and the Dalton Minimum; (ii) to search systematically for the first simultaneous documentary and instrumental data in order to calibrate the series; (iii) to analyse simulated multi-decadal trends over Portugal generated by climate models; (iv) to compare results with those obtained from dendroclimatology and from geothermal studies regarding Portugal and (v) to study extreme events of the past, their impacts and the vulnerability of societies to weather during the last 350 years, and compare them with current analogues. With these tasks, we expect to help completing the spatial coverage of past European climate, as the data gap over SW Europe is often mentioned. As the team members come from four different Universities in Portugal (Évora, Lisbon, Oporto and UTAD), we expect to obtain a good spatial representation of documentary evidence. Teams are now progressing in data search activities in archives. An Access database frame was constructed. Some 18th century extreme events have been and are being studied (Barbara storm, Dec.1739, among others). The first workshop took place in Lisbon (October 2012): Prof Brázdil and Dr. Domínguez-Castro (two of our consultants) were keynote speakers. Key-words: Climate reconstruction, Documentary

    Introdução: A satisfação com a profissão médica tem sido apontada como um fator essencial para a qualidade assistencial, o bemestar dos doentes e a estabilidade dos sistemas de saúde. Estudos recentes têm vindo a enfatizar um crescente descontentamento dos médicos, principalmente como consequência das alterações das relações laborais.Objetivos: Avaliar a perceção dos médicos de formação específica em Portugal, sobre as expectativas e grau de satisfação com a profissão, especialidade e local de formação; razões da insatisfação e intenção de emigrar.Material e Métodos: Estudo transversal. A colheita de dados foi efetuada entre Maio e Agosto de 2014 através de um Inquérito online sobre a âÄúSatisfação com a EspecialidadeâÄù.Resultados: De uma população total de 5788 médicos, foram obtidas 804 respostas (12,25% do total de médicos internos). Desta amostra, 77% das respostas correspondem a internos dos três primeiros anos de formação. Verificou-se que 90% dos médicos se encontram satisfeitos com a especialidade, tendo-se encontrado também níveis elevados de satisfação com a profissão (85%) e local de formação (86%). Por outro lado, constatou-se que estes diminuíam com a progressão ao longo dos anos de internato. A avaliação global sobre o panorama da prática médica foi negativa e 65% dos médicos responderam que consideram emigrar após conclusão do internato.Conclusão: Os médicos internos em Portugal apresentam níveis positivos de satisfação com a sua profissão. No entanto, a sua opinião sobre o panorama da Medicina e os resultados relativos à intenção de emigrar alertam para a necessidade de tomada de medidas para inverter este cenário.

    Full Text Available São representadas cartograficamente as unidades geomorfológicas identificadas para os 89015 km2 do território de Portugal Continental. A delimitação das unidades teve por base a análise dos padrões da textura fornecida por imagens SRTM, com revisão e adaptação posterior à altimetria e à geologia, para os quais foram usadas bases cartográficas digitais. Foram considerados três níveis taxionómicos que permitem descrever e caracterizar áreas homogéneas do ponto de vista geomorfológico. As três unidades de 1º nível baseiam-se nas unidades morfostruturais clássicas consideradas para a Península Ibérica. As dez unidades de 2º nível constituem, na sua maioria, divisões clássicas do relevo de Portugal Continental, agora agrupadas de acordo com a metodologia adoptada e designadas como unidades morfosculturais. As 56 unidades de 3º nível, ou subunidades morfosculturais, foram individualizadas com base nos padrões de relevo identificados nas imagens SRTM e na observação de campo e adquiriram uma designação baseada essencialmente nas geoformas que as individualizam e na toponímia local. As unidades geomorfológicas identificadas são descritas através de características do relevo, dissecação fluvial, estruturas, tipo de drenagem e base geológica, bem como de parâmetros numéricos gerados de forma automática, como classes de altitude e de declividade. Pretende-se que o mapa elaborado possa contribuir para a gestão territorial, em especial na tomada de decisões em conservação da natureza.

    Reservoir computing is a recently introduced, highly efficient bio-inspired approach for processing time dependent data. The basic scheme of reservoir computing consists of a non linear recurrent dynamical system coupled to a single input layer and a single output layer. Within these constraints many implementations are possible. Here we report an optoelectronic implementation of reservoir computing based on a recently proposed architecture consisting of a single non linear node and a delay line. Our implementation is sufficiently fast for real time information processing. We illustrate its performance on tasks of practical importance such as nonlinear channel equalization and speech recognition, and obtain results comparable to state of the art digital implementations.

  2. From Eutrophic to Mesotrophic: Modelling Watershed Management Scenarios to Change the Trophic Status of a Reservoir

    Directory of Open Access Journals (Sweden)

    Marcos Mateus

    2014-03-01

    Full Text Available Management decisions related with water quality in lakes and reservoirs require a combined land-water processes study approach. This study reports on an integrated watershed-reservoir modeling methodology: the Soil and Water Assessment Tool (SWAT model to estimate the nutrient input loads from the watershed, used afterwards as boundary conditions to the reservoir model, CE-QUAL-W2. The integrated modeling system was applied to the Torrão reservoir and drainage basin. The objective of the study was to quantify the total maximum input load that allows the reservoir to be classified as mesotrophic. Torrão reservoir is located in the Tâmega River, one of the most important tributaries of the Douro River in Portugal. The watershed is characterized by a variety of land uses and urban areas, accounting for a total Waste Water Treatment Plants (WWTP discharge of ~100,000 p.e. According to the criteria defined by the National Water Institute (based on the WWTP Directive, the Torrão reservoir is classified as eutrophic. Model estimates show that a 10% reduction in nutrient loads will suffice to change the state to mesotrophic, and should target primarily WWTP effluents, but also act on diffuse sources. The method applied in this study should provide a basis for water environmental management decision-making.

    This final report summarizes the progress during the three years of a project on Reservoir Characterization of Pennsylvanian Sandstone Reservoirs. The report is divided into three sections: (i) reservoir description; (ii) scale-up procedures; (iii) outcrop investigation. The first section describes the methods by which a reservoir can be described in three dimensions. The next step in reservoir description is to scale up reservoir properties for flow simulation. The second section addresses the issue of scale-up of reservoir properties once the spatial descriptions of properties are created. The last section describes the investigation of an outcrop.

Here we study Brazilian immigrants in Portugal, working with the first wave (starting at the end of the 1980s and the second wave (at the turn of the 20th to 21st century. We intend, firstly, to show how identity is reconstructed between two banks: the departure culture and the arrival culture. Secondly, we intend to give a voice to the most silent in the understanding of immigrants: the process of identity reconstruction of Brazilian immigrants is presented, resulting from ethno-biographic interviews. We will consider the cultural transfusion theory and observe the heterogeneous ways of living between cultures, whether by rejecting the departure culture (the Oblato‘s case, refusing the arrival one at a given moment (the mono-cultural subject according to the source culture, living in an ambivalent manner between the two (the multicultural self, or, finally, inventing a third bank, as the poets say, which corresponds to an attitude of including the cultural differences through which one crosses during his or her life history in an intercultural self (the Intercultural Transfuga.

  5. Moderate biomanipulation for eutrophication control in reservoirs using fish captured in angling competitions

    Directory of Open Access Journals (Sweden)

    Amaral S.D.

    2015-01-01

    Full Text Available Angling competitions are a popular leisure activity in reservoirs of Southern Portugal. These competitions can gather more than 100 anglers aiming to catch the maximum fish weight. Groundbaiting and catch-and-release angling are two common practices for anglers in competition. In this study, the loads of nutrients from commercial groundbait powders used in angling competitions in the Maranhão reservoir and the possible balance out of those nutrients through a moderate biomanipulation of the fish biomass caught in competitions were analysed. In order to achieve this aim, chemical analyses to groundbait powders most purchased by Portuguese anglers and to fish species most captured in competitions were made. Mass balances on inputs and outputs of nutrients considering some biomanipulation scenarios were evaluated. Results demonstrated that an effective management on angling competitions implementing a moderate biomanipulation of fish in reservoirs could promote the control of fish fauna and eutrophication, balancing out nutrients from angling.

  6. Census Model Transition: Contributions to its Implementation in Portugal

    Directory of Open Access Journals (Sweden)

    Dias Carlos A.

    2016-03-01

    Full Text Available Given the high cost and complexity of traditional censuses, some countries have started to change the census process. Following this trend, Portugal is also evaluating a new census model as an alternative to an exhaustive collection of all statistical units. The main motivations for the implementation of this census model transition in Portugal are related to the decrease in statistical burden on citizens, improvements in the frequency of outputs, and the reduction of collection costs associated with census operations. This article seeks to systematise and critically review all alternatives to the traditional census methodologies, presenting their advantages and disadvantages and the countries that use them. As a result of the comparison, we conclude that the methods that best meet these objectives are those that use administrative data, either in whole or in part. We also present and discuss the results of an inventory and evaluation of administrative registers in Portugal with the potential to produce statistical census information.

  7. Contribution of natural gas for sustainable development in Portugal

    Directory of Open Access Journals (Sweden)

    Manuela Sarmento

    2010-09-01

    Full Text Available Portugal has strongly limited domestic energy resources, since imports almost 90% of its energy needs and its energy production is totally from renewable energy sources. The addition of natural gas to the Portuguese energy mix in 1997 helped to diversify Portugal’s energy sources and is a contribution to the mitigation of environmental problems. In 1997 also ceased the production and use of domestic coal. In fact, Portugal is working to reduce the growth in energy use and CO2 emissions, in order to follow the Kyoto Protocol. This measure can be linked to environmental sustainability policies, creating the opportunity for new business to appear. Natural gas, in some applications, can substitute the electricity, implying a decrease in price. Security of gas supply is an important issue, since Portugal depends mainly on a single supplier. This paper aims at analysing the emerging gas market, (threats and opportunities, its evolution andcomparison with other OECD countries.

    Full Text Available In recent decades, a significant transformation in the legal professions has been its increasing feminization. However, if in other countries we can find relevant studies on this subject, the gender variable is rarely taken into account in Portugal, except through intuitive and non-scientific processes and discourses that often produce bias and where female judges and public prosecutors have no voice. This article aims to contribute to filling in this empirical lacuna and, based on a survey of the Portuguese population and on interviews with judges and public prosecutors in Portugal, to analyse the existing views on the feminization of justice and female judging.

Traditionelt har reservoirer været styret af heuristiske procedurer for udtag af vand, suppleret i en vis udstrækning af subjektive beslutninger. Udnyttelse af...... reservoirer involverer en lang række interessenter med meget forskellige formål (f.eks. kunstig vanding, vandkraft, vandforsyning mv.), og optimeringsteknik kan langt bedre lede frem til afbalancerede løsninger af de ofte modstridende interesser. Afhandlingen foreslår en række tiltag, hvormed traditionelle...... driftsstrategier kan erstattes af optimale strategier baseret på den nyeste udvikling indenfor computer-baserede beregninger. Hovedbidraget i afhandlingen er udviklingen af et beregningssystem, hvori en simuleringsmodel er koblet til en model for optimering af nogle udvalgte beslutningsvariable, der i særlig grad...

    Full Text Available In this work, the evaluation of the aerosol radiative forcing at the top of the atmosphere as well as at the surface over the south of Portugal is made, particularly in the regions of Évora (38°34' N, 7°54' W and of Cabo da Roca (38°46' N, 9°38' W, during years 2004 and 2005.

    The radiative transfer calculations, using the radiative transfer code Second Simulation of the Satellite Signal in the Solar Spectrum (6S, combine ground-based measurements, from Aerosol Robotic NETwork (AERONET, and satellite measurements, from MODerate Imaging Spectroradiometer (MODIS, to estimate the direct SW aerosol radiative forcing. The method developed to retrieve the surface spectral reflectance is also presented, based on ground-based measurements (AERONET of the aerosol optical properties combined with the satellite-measured radiances (MODIS.

    The instantaneous direct SW aerosol radiative forcing values obtained at the top of the atmosphere are, in the majority of the cases, negative, indicating a tendency for cooling the Earth at the top of the atmosphere. For Desert Dust aerosols, over the Évora land region, the average forcing efficiency is estimated to be −25 Wm−2/AOT0.55 whereas for the Cabo da Roca area, the average forcing efficiency is −46 Wm−2/AOT0.55. In the presence of Forest Fire aerosols, both from short and long distances, the average value of forcing efficiency at the top of the atmosphere over Cabo da Roca is found to be −28 Wm−2/AOT0.55 and, over Évora, −27 Wm−2/AOT0.55. For specific situations, discussed in this work, the average surface direct SW aerosol radiative forcing efficiency due to the Desert Dust aerosols, in Évora region, is −66 Wm−2/AOT0.55, whereas in Cabo da Roca region, the corresponding average value is −38 Wm−2/AOT0.55

    Full Text Available The estimation of radiative forcing due to desert dust and forest fires aerosols is a very important issue since these particles are very efficient at scattering and absorbing both short and longwave radiation. In this work, the evaluation of the aerosol radiative forcing at the top of the atmosphere over the south of Portugal is made, particularly in the regions of Évora and of Cabo da Roca.

    The radiative transfer calculations combine ground-based and satellite measurements, to estimate the top of the atmosphere direct SW aerosol radiative forcing. The method developed to retrieve the surface spectral reflectance is also presented, based on ground-based measurements of the aerosol optical properties combined with the satellite-measured radiances.

    The aerosol direct radiative effect is shown to be very sensitive to the underlying surface, since different surface spectral reflectance values may originate different forcing values. The results obtained also illustrate the importance of considering the actual aerosol properties, in this case measured by ground-based instrumentation, particularly the aerosol single scattering albedo, because different aerosol single scattering albedo values can flip the sign of the direct SW aerosol radiative forcing.

    The instantaneous direct SW aerosol radiative forcing values obtained at the top of the atmosphere are, in the majority of the cases, negative, indicating a tendency for cooling the Earth. For Desert Dust aerosols, over Évora land region, the average forcing efficiency is estimated to be −25 W/m2/AOT0.55 whereas for Cabo da Roca area, the average forcing efficiency is −46 W/m2/AOT0.55. In the presence of Forest Fire aerosols, over Cabo da Roca region, the average value of forcing efficiency is −28 W/m2/AOT0.55 and over Évora region an average value of −33 W/m2/AOT0.55 is found.

    2006-10-01

    Full Text Available Abstract Background Listeriosis is a rare disease caused by the bacterium Listeria monocytogenes, the normal vehicle of which is food. The disease, which is largely confined to its risk groups of pregnant women, the elderly and immunocompromised individuals, has increased in incidence in recent years. In Portugal, listeriosis is not a notifiable infection and available data are scarce. The objective of this work was to collate the available information concerning listeriosis in Portugal by compiling a retrospective study of cases recorded over a decade. Methods Requests for case data on clinically confirmed listeriosis, recorded over the previous decade, were replied to by 23 hospitals and a National Institute of Health delegation. Results 35 cases of listeriosis were identified for the period between 1994 and 2003 inclusive, the mortality rate being greater than 17%. According to the data collected in this study for the year 2003, the incidence of this disease in Portugal was at least 1.4 cases per million inhabitants in that year. Conclusion The study demonstrates, for the first time in the widely available literature, that despite their being no cases of listeriosis in Portugal recorded in official reports, the threat of L. monocytogenes to public health is of a similar dimension to that in other countries.

  18. Occupational radiation doses in Portugal from 1994 to 1998

    International Nuclear Information System (INIS)

    This work reports on the occupational radiation doses for external radiation received in 1994-1998 by the radiation workers monitored by the Radiological Protection and Nuclear Safety Department (DPRSN) in Portugal. Individual monitoring for external radiation is carried out in Portugal by DPRSN since the 60s, and the workers are monitored on a monthly or quarterly bases. In 1995 DPRSN monitored approximately 8000 people and was the only laboratory carrying out this sort of activity in Portugal. In 1998 the number of monitored people increased to nearly 8500 from 860 facilities, which leads us to state that the results shown in this work are well representative of the universe of radiation workers in Portugal. Until 1996, the dose measurement procedure was based only on film dosimetry and the results reported for the 1994-1995 period were obtained with this methodology. Since 1996, thermoluminescent dosimetry (TLD) was gradually introduced and since then an effort has been made to transfer the monitored workers from film to TLD. In 1998, both film and TLD dosimetry systems were running simultaneously, with average numbers of 4500 workers monitored with film dosimetry, while 4000 were monitored with TLD. The data presented from 1996 to 1998 were obtained with both methodologies. This work reports the annual mean effective doses received from external radiation, for the monitored and exposed workers in the different fields of activity, namely, industry, research laboratories, health and mining. The distribution of the annual effective dose by dose intervals is also reported. The collective annual dose by field of activity is estimated and the contribution to the total annual collective dose is determined. The collective dose estimates for the period 1994 to 1998 demonstrated that the health sector is the most representative exposed group in Portugal. (author)

  20. Modeling the Probability of Surface Artificialization in Zêzere Watershed (Portugal Using Environmental Data

    Directory of Open Access Journals (Sweden)

    Bruno M. Meneses

    2016-07-01

    Full Text Available The land use and land cover (LUC of the Zêzere watershed (Portugal have undergone major changes in recent decades, with the increase of artificial surfaces. This trend is quantified in some studies, but the probability of the increase of this type of LUC, nor the places where the next transitions or land use/cover changes (LUCC for artificial surfaces will have high probability of occurrence has not yet been assessed. This research presents an evaluation of these two aspects, by means of bivariate statistical models (fuzzy logic and information value and environmental data. The artificialization probability by sectors within the same watershed is also evaluated, to further understand which areas will require greater attention, taking into account the environmental conditions favorable to the occurrence of this process and bearing in mind the conditions under which this process took place in the past. The results obtained using these models were assessed independently, through curves of success, noting that the modeling through the fuzzy gamma presents slightly better efficiency in determining the probability of artificialization surfaces in the study area. The area with the highest probability of artificialization is mostly located in the SW of this watershed, but high probabilities are also present in the upstream sector, being those areas that require further preventive measures once they have influence on the water quality and quantity in the main reservoirs of this watershed.

  1. Surrogate Reservoir Model

    Mohaghegh, Shahab

    2010-05-01

    Surrogate Reservoir Model (SRM) is new solution for fast track, comprehensive reservoir analysis (solving both direct and inverse problems) using existing reservoir simulation models. SRM is defined as a replica of the full field reservoir simulation model that runs and provides accurate results in real-time (one simulation run takes only a fraction of a second). SRM mimics the capabilities of a full field model with high accuracy. Reservoir simulation is the industry standard for reservoir management. It is used in all phases of field development in the oil and gas industry. The routine of simulation studies calls for integration of static and dynamic measurements into the reservoir model. Full field reservoir simulation models have become the major source of information for analysis, prediction and decision making. Large prolific fields usually go through several versions (updates) of their model. Each new version usually is a major improvement over the previous version. The updated model includes the latest available information incorporated along with adjustments that usually are the result of single-well or multi-well history matching. As the number of reservoir layers (thickness of the formations) increases, the number of cells representing the model approaches several millions. As the reservoir models grow in size, so does the time that is required for each run. Schemes such as grid computing and parallel processing helps to a certain degree but do not provide the required speed for tasks such as: field development strategies using comprehensive reservoir analysis, solving the inverse problem for injection/production optimization, quantifying uncertainties associated with the geological model and real-time optimization and decision making. These types of analyses require hundreds or thousands of runs. Furthermore, with the new push for smart fields in the oil/gas industry that is a natural growth of smart completion and smart wells, the need for real time

  6. Portugal and United States cooperative energy assessment. Volume 3. Reference reports, Part 1

    Energy Technology Data Exchange (ETDEWEB)

    1981-09-01

    Statistical data on energy production and consumption and supporting information were obtained from US Bureau of Mines records supplemented by additional data obtained in Portugal. Geologic descriptions and analysis of known areas and of areas having possible future potential have been prepared by the US Geological Survey. Portugal lacks sufficient indigenous supplies of organic fuels to meet its energy demands, and so must import large quantities of petroleum and coal. Approximately 80% of Portugal's electric energy is produced by hydroelectric stations; thermal stations produce the other 20%. Portugal has produced no crude oil, natural gas, or condensate; no resources or reserves in these categories are listed for Portugal in the 1976 World Energy Conference report. Until the last year or so (1980), no significant onshore petroleum exploration had been done in Portugal since 1963. Production of coal in Portugal has declined steadily to the present annual yield of about 200,000 metric tons. On the basis of estimates in only three coal fields, resources of coal of all ranks in Portugal total at least 76 million (10/sup 6/) metric tons. Uranium is mined near Viseu and Guarda in the northern part of Portugal; the Nisa mine in east-central Portugal will begin producing uranium ore in 1985 after installation of a processing plant. Portugal produced 95 metric tons of uranium oxide (U/sub 3/O/sub 8/) from ore stocks in each year from 1972 through 1974; production is assumed to have continued at the same rate since then. Geothermal energy has not been developed in mainland Portugal; however, hot springs that may have geothermal energy potential are known in the Minho district in the northwest. Geothermal energy resources exist in the Azores and a program of evaluation and exploration with technical assistance from the USGS is presently in progress there.

    Zika virus is an emerging arbovirus transmitted by Aedes sp. mosquitoes like the Dengue and Chikungunya viruses. Zika virus was until recently considered a mild pathogenic mosquito-borne flavivirus with very few reported benign human infections. In 2007, an epidemic in Micronesia initiated the turnover in the epidemiological history of Zika virus and more recently, the potential association with congenital microcephaly cases in Brazil 2015, still under investigation, led the World Health Organization (WHO) to declare a Public Health Emergency of International Concern on February 1, 2016. Here, we present the clinical and laboratory aspects related to the first four imported human cases of Zika virus in Portugal from Brazil, and alert, regarding the high level of traveling between Portugal and Brazil, and the ongoing expansion of this virus in the Americas, for the threat for Zika virus introduction in Europe and the possible introduction to Madeira Island where Aedes aegypti is present.

Overfishing and illegal fishing, pollution, physical barriers and river-bed changes seem to be the main reasons for the populations gradual decline. The progressive reduction in the numbers of anadromous fish registered in the last decades in some Portuguese river basins requires urgent action, namely the implementation of measures to promote the recovery of those populations. The current status of shads populations in Portugal is discussed, and the distribution along the main Portuguese watersheds and major threats to these species are presented, as well.

    Dirofilaria repens causes subcutaneous infection in dogs and cats, and is the main agent of human dirofilariosis in Europe. Detection of D. repens is described in a dog from Portugal, a finding that simultaneously represents the first presumable case of autochthonous infection with the parasite in any animal host species in the country. A mixed D. repens/Dirofilaria immitis infection (20:1 ratio) was found, with an overall density of 1267 microfilariae per millilitre of blood. Morphological features, including morphometry, and acid phosphatase histochemical staining confirmed identity of the two filarioids. Distribution of D. repens in Portugal should be further assessed at the population level both in vertebrate hosts and in vectors. Due to the zoonotic potential of the parasite, preventive measures such as the administration of microfilaricides and insect repellents should be put into practice to protect animals and public health.

    This paper uses a VAR approach to investigate the effects of aggregate and disaggregate measures of public investment in transportation infrastructures on private investment, employment, and output in Portugal. Estimation results suggest that public investment in transportation infrastructures crowds in private investment and employment and, therefore, has a strong positive effect on output. Indeed, we estimate that one euro invested in public investment increases output in the long-term b...

  1. Photovoltaic energy mini-generation: Future perspectives for Portugal

    International Nuclear Information System (INIS)

    This paper evaluates the benefits of developing the mini-generation PV market in Portugal. It presents the legal framework and current status of the Portuguese PV electricity sector, and compares the country to other European nations: France, Germany, Greece, Italy, Spain and the United Kingdom. A model that combines PVGIS with a self-developed financial tool is used to assess the feasibility of a 150 kW mini-generation system using five different technologies: fixed mount, single-axis tracking, double-axis tracking, low concentration and medium concentration (MCPV). The profitability of the mini-generation systems in the seven countries studied is calculated and compared. According to this analysis, MCPV and, of the conventional technologies, the single-axis tracking systems are the most profitable technologies. Despite the attractiveness of the current Portuguese feed-in tariffs and of the abundant solar resource, investors are discouraged and the country's PV market is far from mature. Specific mini-generation regulations should focus on a fast and transparent licensing procedure and should promote the access to financing. This would attract new investments, which would result in the growth of the PV electricity produced, and would help Portugal to meet its European Union Renewable Energy targets. - Highlights: → This work promotes the development of a mini-generation PV market in Portugal. → The Portuguese current status and legal framework is compared to other EU countries. → The profitability of 5 different PV technologies is compared for 7 European countries. → The Portuguese growth potential for PV energy is still big. → Portugal, due to its radiation levels, presents excellent investment opportunities.

    Toxoplasmosis is a worldwide zoonosis. However, data from Portugal are limited and a considerable part of the literature is in Portuguese. Currently, the rate of congenital infection in Portugal is unknown, and almost nothing is known of sequelae of congenital toxoplasmosis. There is no recent general population-based serological survey of Toxoplasma gondii in humans in Portugal. In addition, there is little information on genetic characteristics of T. gondii in animals and humans. In the present paper, we review prevalence, clinical spectrum and epidemiology of T. gondii in humans and animals in Portugal. This knowledge should be useful to biologists, public health workers, physicians and veterinarians.

    Full Text Available A year ago, Portugal celebrated the twenty-fifth anniversary of the so-called Revolution of the Carnations, which marked the beginning of an unstoppable process of democratization and the ensuing full incorporation of Portugal into the institutionalized international community. The Portugal’s opting for orderly decolonialization and full integration into the world of international law has twice brought it a non-permanent seat on the United Nations Security Council and also the Presidency of the UN General Assembly. In the area of security and defense, Portugal began an unprecedented change of course. Its traditional alliance with NATO has been strengthened by new strategic concepts and by its incorporation into new peacekeeping and international security programs in organizations such as the UN, the Western European Union, the OSCE, and even withinthe framework of the European Union where it participates quite actively in accordance with its level in relation to the other members. Also analyzed are the process of incorporation into Community institutions and its direct, precise participation in the evolution they have followed in recent years, with it now being fully integrated into all the areas of regional integration from the "eurozone” to the Schengen framework. The article also points out the gains this very rational choice has brought. Finally, the changes that have come about in bilateral relations with Spain are analyzed.

    Full Text Available This article discusses the issue of taxation of insolvent companies in Portugal, particularly regarding the Portuguese tax on revenue of legal entities (IRC. For this purpose, first, some considerations on the legal framework of insolvent companies are woven and, second, their tax regime is analyzed. Then, a brief review of the main studies that, in the international context, analyze and debate major issues derived from the tax regime of insolvent companies is conducted, particularly in Brazil, Spain, United States, and Italy. Finally, there are the results of an empirical study conducted in Portugal, in 2013, which evaluates and compares the opinions of insolvency administrators (IA, the tax and customs authority (TA, and court magistrates (CM, in order to contribute to a better solution concerning business taxation under this regime. Respondents (IA, TA, CM demonstrate objective thinking about the fact they believe it is very important that the Portuguese Code of Insolvency and Business Recovery (CIRE and the Portuguese Code of Tax on Revenue of Legal Entities (CIRC are modified, now to make clear whether the settlement of property ownership of an insolvent estate is liable to the IRC, then to assign a chapter specifically devoted to the subject of taxation on insolvency in Portugal.

An Internet survey on generic childhood symptoms and diseases was administered to a sample of parents. This self-report survey had been previously implemented in other European countries. Medically confirmed OM was defined as symptoms of earache or “running ear” and/or a diagnosis of OM provided by a medical doctor. Direct medical, nonmedical, and indirect nonmedical costs were calculated for individual cases. Mean total costs per OM episode were estimated at €334. This corresponds to an estimated societal impact of 72 million €/year, of which 39% were indirect nonmedical costs. An epidemiological study should help to confirm the results of this study, and evaluate whether an intervention to reduce the occurrence and/or duration of OM may have an impact on societal costs and quality of life for affected families.Keywords: otitis media, costs, societal burden, Portugal

  19. Geothermal reservoir management

    Energy Technology Data Exchange (ETDEWEB)

    Scherer, C.R.; Golabi, K.

    1978-02-01

    The optimal management of a hot water geothermal reservoir was considered. The physical system investigated includes a three-dimensional aquifer from which hot water is pumped and circulated through a heat exchanger. Heat removed from the geothermal fluid is transferred to a building complex or other facility for space heating. After passing through the heat exchanger, the (now cooled) geothermal fluid is reinjected into the aquifer. This cools the reservoir at a rate predicted by an expression relating pumping rate, time, and production hole temperature. The economic model proposed in the study maximizes discounted value of energy transferred across the heat exchanger minus the discounted cost of wells, equipment, and pumping energy. The real value of energy is assumed to increase at r percent per year. A major decision variable is the production or pumping rate (which is constant over the project life). Other decision variables in this optimization are production timing, reinjection temperature, and the economic life of the reservoir at the selected pumping rate. Results show that waiting time to production and production life increases as r increases and decreases as the discount rate increases. Production rate decreases as r increases and increases as the discount rate increases. The optimal injection temperature is very close to the temperature of the steam produced on the other side of the heat exchanger, and is virtually independent of r and the discount rate. Sensitivity of the decision variables to geohydrological parameters was also investigated. Initial aquifer temperature and permeability have a major influence on these variables, although aquifer porosity is of less importance. A penalty was considered for production delay after the lease is granted.

    Cashman, Katharine; Giordano, Guido

    2015-04-01

    Large caldera-forming eruptions have long been a focus of both petrological and volcanological studies; traditionally, both have assumed that eruptible magma is stored within a single long-lived melt body. Over the past decade, however, advances in analytical techniques have provided new views of magma storage regions, many of which provide evidence of multiple melt lenses feeding a single eruption, and/or rapid pre-eruptive assembly of large volumes of melt. These new petrological views of magmatic systems have not yet been fully integrated into volcanological perspectives of caldera-forming eruptions. We discuss the implications of syn-eruptive melt extraction from complex, rather than simple, reservoirs and its potential control over eruption size and style, and caldera collapse timing and style. Implications extend to monitoring of volcanic unrest and eruption progress under conditions where successive melt lenses may be tapped. We conclude that emerging views of complex magma reservoir configurations provide exciting opportunities for re-examining volcanological concepts of caldera-forming systems

  7. Cesium reservoir and interconnective components

    International Nuclear Information System (INIS)

    The program objective is to demonstrate the technology readiness of a TFE (thermionic fuel element) suitable for use as the basic element in a thermionic reactor with electric power output in the 0.5 to 5.0 MW range. A thermionic converter must be supplied with cesium vapor for two reasons. Cesium atoms adsorbed on the surface of the emitter cause a reduction of the emitter work function to permit high current densities without excessive heating of the emitter. The second purpose of the cesium vapor is to provide space-charge neutralization in the emitter-collector gap so that the high current densities may flow across the gap unattenuated. The function of the cesium reservoir is to provide a source of cesium atoms, and to provide a reserve in the event that cesium is lost from the plasma by any mechanism. This can be done with a liquid cesium metal reservoir in which case it is heated to the desired temperature with auxiliary heaters. In a TFE, however, it is desirable to have the reservoir passively heated by the nuclear fuel. In this case, the reservoir must operate at a temperature intermediate between the emitter and the collector, ruling out the use of liquid reservoirs. Integral reservoirs contained within the TFE will produce cesium vapor pressures in the desired range at typical electrode temperatures. The reservoir material that appears to be the best able to meet requirements is graphite. Cesium intercalates easily into graphite, and the cesium pressure is insensitive to loading for a given intercalation stage. The goals of the cesium reservoir test program were to verify the performance of Cs-graphite reservoirs in the temperature-pressure range of interest to TFE operation, and to test the operation of these reservoirs after exposure to a fast neutron fluence corresponding to seven year mission lifetime. In addition, other materials were evaluated for possible use in the integral reservoir

  14. Reservoir engineering and hydrogeology

    International Nuclear Information System (INIS)

    Summaries are included which show advances in the following areas: fractured porous media, flow in single fractures or networks of fractures, hydrothermal flow, hydromechanical effects, hydrochemical processes, unsaturated-saturated systems, and multiphase multicomponent flows. The main thrust of these efforts is to understand the movement of mass and energy through rocks. This has involved treating fracture rock masses in which the flow phenomena within both the fractures and the matrix must be investigated. Studies also address the complex coupling between aspects of thermal, hydraulic, and mechanical processes associated with a nuclear waste repository in a fractured rock medium. In all these projects, both numerical modeling and simulation, as well as field studies, were employed. In the theoretical area, a basic understanding of multiphase flow, nonisothermal unsaturated behavior, and new numerical methods have been developed. The field work has involved reservoir testing, data analysis, and case histories at a number of geothermal projects

    The four chapters that are described in this report cover a variety of subjects that not only give insight into the understanding of multiphase flow in fractured porous media, but they provide also major contribution towards the understanding of flow processes with in-situ phase formation. In the following, a summary of all the chapters will be provided. Chapter I addresses issues related to water injection in water-wet fractured porous media. There are two parts in this chapter. Part I covers extensive set of measurements for water injection in water-wet fractured porous media. Both single matrix block and multiple matrix blocks tests are covered. There are two major findings from these experiments: (1) co-current imbibition can be more efficient than counter-current imbibition due to lower residual oil saturation and higher oil mobility, and (2) tight fractured porous media can be more efficient than a permeable porous media when subjected to water injection. These findings are directly related to the type of tests one can perform in the laboratory and to decide on the fate of water injection in fractured reservoirs. Part II of Chapter I presents modeling of water injection in water-wet fractured media by modifying the Buckley-Leverett Theory. A major element of the new model is the multiplication of the transfer flux by the fractured saturation with a power of 1/2. This simple model can account for both co-current and counter-current imbibition and computationally it is very efficient. It can be orders of magnitude faster than a conventional dual-porosity model. Part II also presents the results of water injection tests in very tight rocks of some 0.01 md permeability. Oil recovery from water imbibition tests from such at tight rock can be as high as 25 percent. Chapter II discusses solution gas-drive for cold production from heavy-oil reservoirs. The impetus for this work is the study of new gas phase formation from in-situ process which can be significantly

It is a chalk characteristic that permea bility is controlled by the porosity and internal surface of the mud matrix, whereas the larger pores play an insignificant role. Cemented microfossils may take up a significant volume in a wackestone......Reservoir properties of chalk depend on the primary sediment composition as well as on subsequent diagenesis and tectonic events. Chalks of the North Sea almost exclusively have mudstone or wackestone texture. Microfossils may have retained their porosity where degree of diagenesis is low...... reduces porosity at the same time as it increases specific surface and thus cause permeability to be low. In the Central North Sea the silica is quartzitic. Silica rich chalk intervals are typically found in the Ekofisk and Hod formations. In addition to silica, Upper Cretaceous and Palæogene chalks...

    Full Text Available Remote sensed information on vegetation and soil moisture, namely the Normalised Difference Vegetation Index (NDVI and the Soil Water Index (SWI, is employed to monitor the spatial extent, severity and persistence of drought episodes over Continental Portugal, from 1999 to 2006. The severity of a given drought episode is assessed by evaluating the cumulative impact over time of drought conditions on vegetation. Special attention is given to the drought episodes that have occurred in the last decade, i.e., 1999, 2002 and particularly the major event of 2005. During both the 1999 and 2005 drought episodes negative anomalies of NDVI are observed over large sectors of Southern Portugal for up to nine months (out of eleven of the vegetative cycle. On the contrary, the 2002 event was characterized by negative anomalies in the northern half of Portugal and for a shorter period (eight out of eleven months. The impact of soil moisture on vegetation dynamics is evaluated by analyzing monthly anomalies of SWI and by studying the annual cycle of SWI vs. NDVI. While in the case of the drought episode of 1999 the scarcity of water in the soil persisted until spring, in the recent episode of 2005 the deficit in greenness was already apparent at the end of summer. The impact of dry periods on vegetation is clearly observed in both arable land and forest, and it is found that arable land presents a higher sensitivity. From an operational point of view, obtained results reveal the possibility of using the developed methodology to monitor, in quasi real-time, vegetation stress and droughts in Mediterranean ecosystems.

    2016-01-01

    The objective of this paper is to analyse temporal birth weight variation, its relationship to the frequency of premature births in Portugal, and the influence of native and immigrant mothers' characteristics as well as to determine the possible existence of a pattern of temporal change in birth weight in the Iberian Peninsula as a whole. Individual mother-child data from the Portuguese National Institute of Statistics regarding live births (N = 2,661,542) permitted an analysis, for the first time, of weight at birth in Portugal from a bio-demographic perspective. The results obtained show that from 1988 to 2011 there was a gradual decline in the average weight at birth in Portugal that may be related to shifts in the duration of gestation. An initial rapid decline in the relative frequency of post-term births took place, followed by small variations from 1995 on. Logistic regressions indicated a pattern unaffected by maternal origin or the sex of the newborn. With regard to weeks of gestation, the odds values obtained were < 1 when the reference category was < 28 weeks. For this factor, no significant differences were found in relation to the mother's origin. Portuguese mothers over 35 years were associated with a higher incidence of low birth weight. Regardless of maternal origin, being a newborn of parity 1, and with the mother not in a couple, resulted in unfavourable outcomes with regard to low birth weight. On the other hand, long gestation periods and having secondary or university education constituted a protective factor.

  20. Reservoir Systems in Changing Climate

    2007-12-01

    Climate change may cause more climate variability and further results in more frequent extreme hydrological events which may greatly influence reservoir¡¦s abilities to provide service, such as water supply and flood mitigation, and even danger reservoir¡¦s safety. Some local studies have identified that climate change may cause more flood in wet period and less flow in dry period in Taiwan. To mitigate climate change impacts, more reservoir space, i.e. less storage, may be required to store higher flood in wet periods, while more reservoir storage may be required to supply water for dry periods. The goals to strengthen adaptive capacity of water supply and flood mitigation are conflict under climate change. This study will focus on evaluating the impacts of climate change on reservoir systems. The evaluation procedure includes hydrological models, a reservoir water balance model, and a water supply system dynamics model. The hydrological models are used to simulate reservoir inflows under different climate conditions. Future climate scenarios are derived from several GCMs. Then, the reservoir water balance model is developed to calculate reservoir¡¦s storage and outflows according to the simulated inflows and operational rules. The ability of flood mitigation is also evaluated. At last, those outflows are further input to the system dynamics model to assess whether the goal of water supply can still be met. To mitigate climate change impacts, the implementing adaptation strategies will be suggested with the principles of risk management. Besides, uncertainties of this study will also be analyzed. The Feitsui reservoir system in northern Taiwan is chosen as a case study.

    Dirofilariosis is a severe vector-borne emergent disease that is spreading worldwide and becoming a serious threat to human and veterinary public health. Portugal, a Mediterranean country, has favorable climate conditions for mosquito development and survival. At present, accurate data on the prevalence and epidemiological pattern of dirofilariosis in Portugal is scarce and outdated. To study these trends, a project was developed to assess the current prevalence of Dirofilaria immitis infection in shelter dogs as well as the prevalence of Dirofilaria species present in three coastal regions in central Portugal: Coimbra, Santarém, and Setúbal. Blood samples were collected from 696 shelter dogs during three consecutive years: 2011, 2012, and 2013. A rapid immunomigration technique was performed to detect female D. immitis antigens. Concurrently, to detect and identify circulating microfilariae, a modified Knott's technique and acid phosphatase histochemical staining were also performed. Of the 696 dogs sampled, 105 were positive for D. immitis, with an overall prevalence of 15.1%. Forty of the 105 dogs were antigen negative but were positive for D. immitis microfilariae. Three animals were co-infected with D. immitis and Acanthocheilonema dracunculoides, and there was also one dog infected only with A. dracunculoides, all confirmed by polymerase chain reaction. The highest prevalence of canine heartworm during the 3-y period was in Setúbal (24.8%), followed by Coimbra (13.8%), and Santarém (13.2%), with significant inter-district differences. Our results demonstrate a higher prevalence of dirofilariosis compared with findings of previous studies and show an increasing rate of infection in the southern areas of Portugal attributed, at least in part, to bioclimatic and ecological factors. The present study updates the epidemiological situation and correlates the risk of dirofilariosis transmission within each region. These findings are highly relevant to both human

  20. The Bologna Process in Portugal and Poland: A comparative study

    Full Text Available We analyze the consequences of the introduction of the EU directed Bologna Process in Portuguese and Polish Universities. Specifically, we study how the Bologna Process has impacted in the employment situations of graduates in Portugal and Poland. Concerning methodology, we use available official data on the implementation of the Bologna Process in Poland and Portugal. We have found that the investment in Higher Education (HE stalled in both countries in the years since the implementation of the Bologna Process due to massive budgetary restrictions. Nevertheless, the stock of HE graduates increased massively, seemingly because the authorities thought that the free market should lead the HE market in the two countries. Employment prospects, unemployment prospects and wages of graduates continued to be much higher than those of non-graduates. But an unexpected divide appeared between graduates and Masters/PhDs, with important social consequences. While the first “saved” themselves and prospered going into high skilled jobs, the later had to endure minimum wage and underskilled occupations. The low payment for these youngsters was also justified because the supply of HE with Bologna increased but the demand by companies did not match. In fact, both Portugal and Poland have stronger needs in the demand side of the market than in the supply side. Finally, both markets continue to be essentially public and the experiences of privatization did not succeed to much. In terms of social implications, the Bologna Process faces in both countries the massive and decisive challenge of eliminating youth unemployment and emigration but this can only be done with the cooperation of companies that should create high paid and high skilled jobs. Only when this occurs the Bologna Process will achieve its ultimate goal of transforming Portugal and Poland in high skilled equibriuns. Let us hope it happens, for the good of the two countries and particularly for the

    The project objective was to detail better ways to assess and exploit intelligent oil and gas field information through improved modeling, sensor technology, and process control to increase ultimate recovery of domestic hydrocarbons. To meet this objective we investigated the use of permanent downhole sensors systems (Smart Wells) whose data is fed real-time into computational reservoir models that are integrated with optimized production control systems. The project utilized a three-pronged approach (1) a value of information analysis to address the economic advantages, (2) reservoir simulation modeling and control optimization to prove the capability, and (3) evaluation of new generation sensor packaging to survive the borehole environment for long periods of time. The Value of Information (VOI) decision tree method was developed and used to assess the economic advantage of using the proposed technology; the VOI demonstrated the increased subsurface resolution through additional sensor data. Our findings show that the VOI studies are a practical means of ascertaining the value associated with a technology, in this case application of sensors to production. The procedure acknowledges the uncertainty in predictions but nevertheless assigns monetary value to the predictions. The best aspect of the procedure is that it builds consensus within interdisciplinary teams The reservoir simulation and modeling aspect of the project was developed to show the capability of exploiting sensor information both for reservoir characterization and to optimize control of the production system. Our findings indicate history matching is improved as more information is added to the objective function, clearly indicating that sensor information can help in reducing the uncertainty associated with reservoir characterization. Additional findings and approaches used are described in detail within the report. The next generation sensors aspect of the project evaluated sensors and packaging

    2005-11-10

    The burst test is used to assess the material performance of tritium reservoirs in the surveillance program in which reservoirs have been in service for extended periods of time. A materials system model and finite element procedure were developed under a Savannah River Site Plant-Directed Research and Development (PDRD) program to predict the structural response under a full range of loading and aged material conditions of the reservoir. The results show that the predicted burst pressure and volume ductility are in good agreement with the actual burst test results for the unexposed units. The material tensile properties used in the calculations were obtained from a curved tensile specimen harvested from a companion reservoir by Electric Discharge Machining (EDM). In the absence of exposed and aged material tensile data, literature data were used for demonstrating the methodology in terms of the helium-3 concentration in the metal and the depth of penetration in the reservoir sidewall. It can be shown that the volume ductility decreases significantly with the presence of tritium and its decay product, helium-3, in the metal, as was observed in the laboratory-controlled burst tests. The model and analytical procedure provides a predictive tool for reservoir structural integrity under aging conditions. It is recommended that benchmark tests and analysis for aged materials be performed. The methodology can be augmented to predict performance for reservoir with flaws.

    The Geothermal Reservoir Well Stimulation Project has prepared a two-year program to develop and field test methods of stimulating geothermal wells. The program provides for six field experiments which progress in difficulty from low temperature reservoirs using current technology to high temperature reservoirs using advanced types of stimulation treatments. The process used to select the six field experiment locations and stimulation treatments is described. Tentatively, the following reservoirs are proposed: Raft River, East Mesa, Baca and Westmorland (two experiments), and Brawley and The Geysers or Roosevelt Hot Springs (two experiments). The program will be reviewed after each field treatment to select a specific well candidate for the next experiment and to determine whether alteration of the sequence will be beneficial to the overall success of the project and the geothermal industry.

    Full Text Available OBJECTIVE To analyze the direct medical costs of HIV/AIDS in Portugal from the perspective of the National Health Service. METHODS A retrospective analysis of medical records was conducted for 150 patients from five specialized centers in Portugal in 2008. Data on utilization of medical resources during 12 months and patients’ characteristics were collected. A unit cost was applied to each care component using official sources and accounting data from National Health Service hospitals. RESULTS The average cost of treatment was 14,277 €/patient/year. The main cost-driver was antiretroviral treatment (€ 9,598, followed by hospitalization costs (€ 1,323. Treatment costs increased with the severity of disease from € 11,901 (> 500 CD4 cells/µl to € 23,351 (CD4 count ≤ 50 cells/ µl. Cost progression was mainly due to the increase in hospitalization costs, while antiretroviral treatment costs remained stable over disease stages. CONCLUSIONS The high burden related to antiretroviral treatment is counterbalanced by relatively low hospitalization costs, which, however, increase with severity of disease. The relatively modest progression of total costs highlights that alternative public health strategies that do not affect transmission of disease may only have a limited impact on expenditure, since treatment costs are largely dominated by constant antiretroviral treatment costs.

    Solar salinas are man-made systems exploited for the extraction of salt, by solar and wind evaporation of seawater. Salt production achieved by traditional methods is associated with landscapes and environmental and patrimonial values generated throughout history. Since the mid-twentieth century, this activity has been facing a marked decline in Portugal, with most salinas either abandoned or subjected to destruction, making it necessary to find a strategy to reverse this trend.It is, however, possible to generate revenue from salinas at several levels, not merely in terms of good quality salt production, but also by obtaining other products that can be commercialized, or by exploring their potential for tourism, and as research facilities, among others. Furthermore, with an adequate management, biodiversity can be restored to abandoned salinas, which constitute important feeding and breeding grounds for resident and migratory aquatic birds, many of which are protected by European Community Directives.The aims of this manuscript are to present a brief overview on the current state of sea salt exploitation in Portugal and to stress the importance of recovering these salinas for the conservation of this particular environment, for the regional economy, the scientific community and the general public. The Aveiro salina complex is presented in detail, to exemplify salina structure and functioning, as well as current problems and potential solutions for artisanal salinas.

    Full Text Available Agro-food companies are aware that the technical and soft skills of their employees directly influence business performance and, consequently, improving those skills will enhance the effectiveness and efficiency of their companies. This paper presents the main results of the AgriTraining project “Training requirements for the agro-food industry". Activities in pursuit of the objectives of this project involved: (1 analysis of the training needs in the agro-food industry in Portugal; (2 analysis of the training provision and the training organizations; (3 analysis of market trends; (4 definition of a training strategy; and (5 adjustment and development of training strategies for the agro-food sector. This last activity comprised the development of training curricula, suitable for the food sector as a whole and adjusted for the specific needs of some traditional industries, in order to promote the development and competitiveness of the agro-food industry in Portugal. Such training curricula aimed to promote the uptake of innovative technologies and methodologies, increase the ability of agro-food industries to invest and take risks, and enable adoption of European Community standards for production and marketing. Gaps in training supply were identified and the training provision was updated according to the needs of the agro-food companies. It was determined that companies need and demand knowledge and innovation to increase their competitive position for internationalization purposes. It was possible to define a training strategy based on market-orientation for agro-food differentiation.

    Full Text Available The spatial variability of precipitation and drought are investigated for Portugal using monthly precipitation from 74 stations and minimum and maximum temperature from 27 stations, covering the common period of 1941–2006. Seasonal precipitation and the corresponding percentages in the year, as well as the precipitation concentration index (PCI, was computed for all 74 stations and then used as an input matrix for an R-mode principal component analysis to identify the precipitation patterns. The standardized precipitation index at 3 and 12 month time scales were computed for all stations, whereas the Palmer Drought Severity Index (PDSI and the modified PDSI for Mediterranean conditions (MedPDSI were computed for the stations with temperature data. The spatial patterns of drought over Portugal were identified by applying the S-mode principal component analysis coupled with varimax rotation to the drought indices matrices. The result revealed two distinct sub-regions in the country relative to both precipitation regimes and drought variability. The analysis of time variability of the PC scores of all drought indices allowed verifying that there is no linear trend indicating drought aggravation or decrease. In addition, the analysis shows that results for SPI-3, SPI-12, PDSI and MedPDSI are coherent among them.

    Trichinellosis is one of the most important foodborne parasitic zoonoses, caused by nematodes of the genus Trichinella. Pigs and other domestic and wild animals, including red foxes (Vulpes vulpes), are sources of Trichinella infection for human beings. Trichinella britovi is the major agent of infection in sylvatic animals and the most important species circulating in the European wildlife. The present study aimed at assessing Trichinella spp. infection in red foxes from the North of Portugal. Forty-seven carcasses of wild red foxes shot during the official hunting season or killed in road accidents were obtained between November 2008 and March 2010. In order to identify the presence of Trichinella spp. larvae in red foxes, an individual artificial digestion was performed using approximately 30 g of muscle samples. Larvae of Trichinella spp. were detected in one (2.1%) out of the 47 assessed foxes. After a multiplex polymerase chain reaction analysis, T. britovi was molecularly identified as the infecting species. The recognition of T. britovi in a red fox confirms that a sylvatic cycle is present in the North of Portugal and that the local prevalence of Trichinella infection in wildlife must not be ignored due to its underlying zoonotic risks.

    A series of experiments were conducted to characterize formaldehyde and acetaldehyde emissions from residential combustion of common wood species growing in Portugal. Five types of wood were investigated: maritime pine (Pinus pinaster), eucalyptus (Eucalyptus globulus), cork oak (Quercus suber), holm oak (Quercus rotundifolia) and pyrenean oak (Quercus pyrenaica). Laboratory experiments were performed with a typical wood stove used for domestic heating in Portugal and operating under realistic home conditions. Aldehydes were sampled from diluted combustion flue gas using silica cartridges coated with 2,4-dinitrophenylhydrazine and analyzed by high performance liquid chromatography with diode array detection. The average formaldehyde to acetaldehyde concentration ratio (molar basis) in the stove flue gas was in the range of 2.1-2.9. Among the tested wood types, pyrenean oak produced the highest emissions for both formaldehyde and acetaldehyde: 1772 ± 649 and 1110 ± 454 mg kg-1 biomass burned (dry basis), respectively. By contrast, maritime pine produced the lowest emissions: 653 ± 151 and 371 ± 162 mg kg-1 biomass (dry basis) burned, respectively. Aldehydes were sampled separately during distinct periods of the holm oak wood combustion cycles. Significant variations in the flue gas concentrations were found, with higher values measured during the devolatilization stage than in the flaming and smoldering stages.

    Climate change in the Mediterranean region is expected to affect existing water resources, both in quantity and quality, as decreased mean annual precipitation and more frequent extreme precipitation events are likely to occur. Also, energy needs tend to increase, together with growing awareness that fossil fuels emissions are determinately responsible for global temperature rise, enhancing renewable energy use and reinforcing the importance of hydropower. When considered together, these facts represent a relevant threat to multipurpose reservoir operations. Great Lisbon main water supply (for c.a. 3 million people), managed by EPAL, is located in Castelo de Bode Reservoir, in the Tagus River affluent designated as Zêzere River. Castelo de Bode is a multipurpose infrastructure as it is also part of the hydropower network system of EDP, the main power company in Portugal. Facing the risk of potential climate change impacts on water resources availability, and as part of a wider project promoted by EPAL (designated as ADAPTACLIMA), climate change impacts on the Zêzere watershed where evaluated based on climate change scenarios for the XXI century. A sequential modeling approach was used and included downscaling climate data methodologies, hydrological modeling, volume reservoir simulations and water quality modeling. The hydrological model SWAT was used to predict the impacts of the A2 and B2 scenarios in 2010-2100, combined with changes in socio-economic drivers such as land use and water demands. Reservoir storage simulations where performed according to hydrological modeling results, water supply needs and dam operational requirements, such as minimum and maximum operational pool levels and turbine capacity. The Ce-Qual-W2 water quality model was used to assess water quality impacts. According to climate scenarios A2 and B2, rainfall decreases between 10 and 18% are expected by 2100, leading to drier climatic conditions and increased frequency and magnitude of

    Full Text Available The Surduc reservoir was projected to ensure more water when water is scarce and to thus provide especially the city Timisoara, downstream of it with water.The accumulation is placed on the main affluent of the Bega river, Gladna in the upper part of its watercourse.The dam behind which this accumulation was created is of a frontal type made of enrochements with a masque made of armed concrete on the upstream part and protected/sustained by grass on the downstream. The dam is 130m long on its coping and a constructed height of 34 m. It is also endowed with spillway for high water and two bottom outlets formed of two conduits, at the end of which is the microplant. The second part of my paper deals with the hydrometric analysis of the Accumulation Surduc and its impact upon the flow, especially the maximum run-off. This influence is exemplified through the high flood from the 29th of July 1980, the most significant flood recorded in the basin with an apparition probability of 0.002%.

    Introduced a decade ago, reservoir computing is an efficient approach for signal processing. State of the art capabilities have already been demonstrated with both computer simulations and physical implementations. If photonic reservoir computing appears to be promising a solution for ultrafast nontrivial computing, all the implementations presented up to now require digital pre or post processing, which prevents them from exploiting their full potential, in particular in terms of processing speed. We address here the possibility to get rid simultaneously of both digital pre and post processing. The standalone fully analogue reservoir computer resulting from our endeavour is compared to previous experiments and only exhibits rather limited degradation of performances. Our experiment constitutes a proof of concept for standalone physical reservoir computers.

    1992-12-01

    The objectives of this report are three-fold: (1) assess physical, chemical, and biological conditions in the major embayments of Chickamauga Reservoir; (2) compare water quality and biological conditions of embayments with main river locations; and (3) identify any water quality concerns in the study embayments that may warrant further investigation and/or management actions. Embayments are important areas of reservoirs to be considered when assessments are made to support water quality management plans. In general, embayments, because of their smaller size (water surface areas usually less than 1000 acres), shallower morphometry (average depth usually less than 10 feet), and longer detention times (frequently a month or more), exhibit more extreme responses to pollutant loadings and changes in land use than the main river region of the reservoir. Consequently, embayments are often at greater risk of water quality impairments (e.g. nutrient enrichment, filling and siltation, excessive growths of aquatic plants, algal blooms, low dissolved oxygen concentrations, bacteriological contamination, etc.). Much of the secondary beneficial use of reservoirs occurs in embayments (viz. marinas, recreation areas, parks and beaches, residential development, etc.). Typically embayments comprise less than 20 percent of the surface area of a reservoir, but they often receive 50 percent or more of the water-oriented recreational use of the reservoir. This intensive recreational use creates a potential for adverse use impacts if poor water quality and aquatic conditions exist in an embayment.

  5. Capacity sharing of water reservoirs

    Science.gov (United States)

    Dudley, Norman J.; Musgrave, Warren F.

    1988-05-01

    The concept of a water use property right is developed which does not apply to water volumes as such but to a share of the capacity (not contents) of river storage reservoirs and their inflows. The shareholders can withdraw water from their share over time in accordance with their preferences for stability of water deliveries. The reservoir authority does not manage reservoir releases but keeps record of individual shareholder's withdrawals and net inflows to monitor the quantity of water in each shareholder's capacity share. A surplus of total reservoir contents over the sum of the contents of the individual shareholder's capacity shares will accrue over time. Two different criteria for its periodic distribution among shareholders are compared. A previous paper Dudley (this issue(b)) noted a loss of short-run economic efficiency as reservoir and farm management decision making become separated. This is largely overcome by capacity sharing which allows each user to integrate the management of their portion of the reservoir and their farming operations. The nonattenuated nature of the capacity sharing water rights also promotes long-run economic efficiency.

  6. Reservoir characterization of Pennsylvanian Sandstone Reservoirs. Annual report

    1992-09-01

    This annual report describes the progress during the second year of a project on Reservoir Characterization of Pennsylvanian Sandstone Reservoirs. The report is divided into three sections: (i) reservoir description and scale-up procedures; (ii) outcrop investigation; (iii) in-fill drilling potential. The first section describes the methods by which a reservoir can be characterized, can be described in three dimensions, and can be scaled up with respect to its properties, appropriate for simulation purposes. The second section describes the progress on investigation of an outcrop. The outcrop is an analog of Bartlesville Sandstone. We have drilled ten wells behind the outcrop and collected extensive log and core data. The cores have been slabbed, photographed and the several plugs have been taken. In addition, minipermeameter is used to measure permeabilities on the core surface at six inch intervals. The plugs have been analyzed for the permeability and porosity values. The variations in property values will be tied to the geological descriptions as well as the subsurface data collected from the Glen Pool field. The third section discusses the application of geostatistical techniques to infer in-fill well locations. The geostatistical technique used is the simulated annealing technique because of its flexibility. One of the important reservoir data is the production data. Use of production data will allow us to define the reservoir continuities, which may in turn, determine the in-fill well locations. The proposed technique allows us to incorporate some of the production data as constraints in the reservoir descriptions. The technique has been validated by comparing the results with numerical simulations.

    A new 'growing' maximum likelihood classification algorithm for small reservoir delineation has been developed and is tested with Radarsat-2 data for reservoirs in the semi-arid Upper East Region, Ghana. The delineation algorithm is able to find the land-water boundary from SAR imagery for different weather and environmental conditions. As such, the algorithm allows for remote sensed operational monitoring of small reservoirs. Multipurpose small reservoirs (1-100 ha) are important for many livelihoods in rural semi-arid West Africa. In order to manage and plan these reservoirs and to assess their hydrological impact at a river basin scale, it is important to monitor their water storage fluctuation. Several studies on remotely sensed reservoir mapping have recently been published, but no single method yields good results for all weather and environmental conditions. Detection of small reservoirs from optical satellite imagery using supervised maximum likelihood classification is a well proved method. The application of this method for the monitoring of small reservoirs is however limited because of its dependence on cloud-free day-acquisitions. Delineation from SAR images is promising, but because of difficulties with wind induced Bragg-scattering and low contrast between the water surface and the dried-out surroundings at the end of the dry season, only quasi manual methods have been applied successfully. A smart combination of optical satellite based detection combined with a delineation method for SAR imagery is proposed. From the optical satellite based small reservoir detection the reservoir window is determined in which the 'growing' maximum likelihood classification on SAR images is performed. A water-class seed and land-class seed are implemented and grown dependent on the likelihood of a pixel to belong to one class. The likelihood is calculated based on the probability distributions of the growing land and water populations. Combinations of single

    Shaken Baby Syndrome (SBS) is an unquestionable and current worldwide problem, as it is considered one of the most severe forms of child abuse, with significant morbidity and mortality among children under one year of age. In Portugal the actual incidence of SBS is still unknown and probably undervalued and underdiagnosed, but international literature reports incidences between 14 and 40.5 per 100.000 children a year in several different countries. It is classically considered SBS to consist of shaking a child repeatedly and violently, inducing a cervical whiplash like movement. Due to the child's development stage, this external force of acceleration/deceleration acting on the head and cervical musculature may cause several lesions, specially subdural, subarachnoid and retinal hemorrhage, and sometimes even bone fractures. However, there is no unanimity concerning this trauma mechanism, especially on the requirement of direct trauma to the head leading to intracranial lesions, since a satisfactory biomechanical model to test it is still lacking. Its diagnosis is controversial, difficult and has important legal and family implications, always adding an emotional element to it, susceptible of withholding the necessary objectivity. In order to substantiate a strong suspicion it is thus mandatory to correlate the clinical history, the physical examination and all the diagnostic auxiliary exams. Consequences may range from mild to fatal, encompassing the child's psychological, cognitive, physical and sensory-motor development, on a short or long term basis. Nevertheless, from a global perspective, its prognosis is almost always poor. So, education and prevention assume primary importance in order to reduce incidence, morbidity and mortality of the SBS. Countries like the U.S.A, Scotland, France, Germany, Switzerland, Canada, Estonia and Japan have long been interested in studying this syndrome's trauma mechanism and incidence, as well as in the development of

    Ançã is located in the Lusitanian Basin (western Meso-Cenozoic sedimentary basin), in the municipality of Cantanhede, close to Coimbra, Portugal. This constitutes the northernmost Dogger (Bajocian) limestone sequence in Portugal. The use of the Ançã limestones is documented since the Roman occupation of the Iberian Peninsula. It was used for the construction of houses, palaces, churches, fine sculptures, carving, paving and for the production of lime. These limestones vary from white and very soft varieties, with very high porosity used for sculpture and carving to white and hard varieties used for masonry and as aggregates and to white to bluish with low porosity and high strength varieties, mainly used for paving. The softer and whiter variety is worldwide known as Ançã Stone (Pedra de Ançã) exhibiting a porosity of 26-29 %. It became famous after being largely used by Coimbra most famous Renaissance sculptors like João de Ruão and Nicolau de Chanterenne. The Pedra de Ançã was used mainly in the region of Coimbra, but also in several other places in Portugal, in Santiago de Compostela, Spain, and Brazil. Some examples of heritage in Coimbra using the Pedra de Ançã are the renaissance portal of the Saint Cross Church, the tombs of the first two Portuguese kings located in this church, the altar of the Saint Cross Church or of the Old Cathedral, or in sculptures at the University of Coimbra. It is quite prone to deteriorate when exposed to atmospheric agents and to soluble salts, mainly due to its high porosity. Deteriorated surfaces needing treatment constitute difficult conservation problems, especially when consolidation and protection treatments are required.

Compared to the other Mediterranean countries, the number of events registered here from 1980 up to nowadays is the highest one; likewise, with respect to the burnt area, Portugal is the third most affected country. Portuguese mapped burnt areas are available from the website of the Institute for the Conservation of Nature and Forests (ICNF). This official geodatabase is the result of satellite measurements starting from the year 1990. The spatial information, delivered in shapefile format, provides a detailed description of the shape and the size of area burnt by each fire, while the date/time information relate to the ignition fire is restricted to the year of occurrence. In terms of a statistical formalism wildfires can be associated to a stochastic point process, where events are analysed as a set of geographical coordinates corresponding, for example, to the centroid of each burnt area. The spatio/temporal pattern of stochastic point processes, including the cluster analysis, is a basic procedure to discover predisposing factorsas well as for prevention and forecasting purposes. These kinds of studies are primarily focused on investigating the spatial cluster behaviour of environmental data sequences and/or mapping their distribution at different times. To include both the two dimensions (space and time) a comprehensive spatio-temporal analysis is needful. In the present study authors attempt to verify if, in the case of wildfires in Portugal, space and time act independently or if, conversely, neighbouring events are also closer in time. We present an application of the spatio-temporal K-function to a long dataset (1990-2012) of mapped burnt areas. Moreover, the multivariate K-function allowed checking for an eventual different distribution between small and large fires. The final objective is to elaborate a 3D

    Located on the western Iberian Peninsula, Portugal constitutes a key area for accretionary terrane and basin research, providing the best opportunity to probe a crustal formation shaped by the Paleozoic Variscan orogeny followed by the Mesozoic-Cenozoic extensions. The geology of Portugal documents a protracted history from Paleozoic basement formation to the Mesozoic opening of the North Atlantic Ocean. The inheritance of such complex geologic history is yet to be fully determined, playing an important role in the current geodynamic framework influencing, for example, the observed regional seismicity. The physical properties of its crust have largely remained undetermined so far, with unevenly distributed knowledge on the spatial distributions of a detailed crustal structure. Also, the deep seismic reflection/refraction surveys conducted in Western Iberia do not provide a clear picture of the regional characteristics of the crust. Using Seismic Broad Band observations from a dense temporary deployment, conducted between 2010 and 2012 in the scope of the WILAS project and covering the entire Portuguese mainland, we computed a 3D anisotropic model from ambient seismic noise. The dispersion measurements were computed for each station pair using empirical Green's functions generated by cross-correlating one-day-length seismic ambient-noise records. After dispersion analysis, group velocity measurements were regionalized to obtain 2D anisotropic tomographic images. Afterwards, the dispersion curves, extracted from each cell of the 2D group velocity maps, were inverted as a function of depth to obtain a 3D shear wave anisotropic model, using a bayesian approach. A simulated annealing method, in which the number of splines that describes the model, is adapted within the inversion. The models are jointly interpreted with the models gathered from Ps receiver functions as well as with the regional seismicity, enabling to obtain a more detailed picture of the crustal

    Full Text Available This paper examines the relationship between corporate ownership structure in Portugal and earnings management. The Portuguese governance structure is characterised by the dominance ofthe largest shareholder who typically exercises significant influences on management decisions directly or indirectly. Existing literature suggests that ownership structure decreases the incentive to manage earnings but also provides the opportunity and incentive to manipulate earnings. Therefore, the main purpose of this paper is to analyse whether a firm’s ownership structure (measured with three variables: managerial ownership, ownership concentration and institutional ownershipexacerbate or alleviate earnings management. Using a sample of 34 non-financial listed Portuguese firms for years from 2002 to 2007, we find that discretionary accruals as a proxy for earnings management is negatively related both to managerial ownership and to ownership concentration. The study’s results suggest that both managerial ownership and ownership concentration improvethe quality of annual earnings by reducing the levels of earnings management.

    Full Text Available Facing the challenges brought by Higher Education growth, the Higher Education Institutions (HEIs created the Psychological Support Services. They seek to help the adaptation to the university setting, enhancing the overall students´ development and their integration in the labor market. This qualitative research studies the structure of the Psychological Support Services in HEIs of Portugal and the main activities developed by educational psychologists. Interviews were conducted with eight services and showed that all services are designed for students. Although the most frequent activity is the students' psychological consultation, educational psychologists also develop a variety of interventions: skill development programs, support to students with special needs, and mentoring programs to welcome new students. Traditionally the services were oriented by an individual intervention and in response to the students' problem. Nowadays they are working with other agents and in a preventive way. Actions directed to educational projects and the institutional evaluation could promote a qualitative change in services.

  19. Assessing fire risk in Portugal during the summer fire season

    2009-04-01

    Since 1998, Instituto de Meteorologia, the Portuguese Weather Service has relied on the Canadian Fire Weather Index (FWI) System (van Wagner, 1987) to produce daily forecasts of fire risk. The FWI System consists of six components that account for the effects of fuel moisture and wind on fire behavior. The first three components, i.e. the Fine Fuel Moisture Code (FFMC), the Duff Moisture Code (DMC) and the Drought Code (DC) respectively rate the average moisture content of surface litter, decomposing litter, and organic (humus) layers of the soil. Wind effects are then added to FFMC leading to the Initial Spread Index (ISI) that rates fire spread. The remaining two fuel moisture codes (DMC and DC) are in turn combined to produce the Buildup Index (BUI) that is a rating of the total amount of fuel available for combustion. BUI is finally combined with ISI to produce the Fire Weather Index (FWI) that represents the rate of fire intensity. Classes of fire danger and levels of preparedness are commonly defined on an empirical way for a given region by calibrating the FWI System against wildfire activity as defined by the recorded number of events and by the observed burned area over a given period of time (Bovio and Camia, 1998). It is also a well established fact that distributions of burned areas are heavily skewed to the right and tend to follow distributions of the exponential-type (Cumming, 2001). Based on the described context, a new procedure is presented for calibrating the FWI System during the summer fire season in Portugal. Two datasets were used covering a 28-year period (1980-2007); i) the official Portuguese wildfire database which contains detailed information on fire events occurred in the 18 districts of Continental Portugal and ii) daily values of the six components of the FWI System as derived from reanalyses (Uppala et al., 2005) of the European Centre for Medium-Range Weather Forecasts (ECMWF). Calibration of the FWI System is then performed in two

    Laukkanen, Tommi; Cruz, Pedro

    This study compares two distinct European countries namely Finland and Portugal in terms of consumer resistance to mobile banking services. We explored how the five adoption barriers namely usage, value, risk, tradition and image, derived from the earlier literature, differ between these two countries. Using an Internet questionnaire a total of 3.597 usable responses was collected. A confirmatory factor analysis was implemented with SEM to build the constructs’ latent score levels. Using non-parametric difference tests we concluded that the resistance is significantly lower among the Portuguese online bank customers in terms of four out of the five barriers. The results can be used for a better understanding and enhancement of adoption of this specific case of mobile communication.

We study whether religion (measured as church attendance and opinions about moral issues influences voting for the two main political parties. Results show a different relationship between religion and voting in both countries: only in Spain religious beliefs play an important role in electoral behaviour. We claim that to account for this finding several factors need to be considered, namely the different configuration of the party systems and religious maps, the distinctive mechanisms linking religious identities with voting and, above all, the important role played by political leaders in activating religiosity within the electoral competition.

    Acute viral bronchiolitis is a common cause for infant hospital admissions. Of all etiological agents, respiratory syncytial virus (RSV) is commonly the most frequent. The present study assesses relationships between atmospheric factors and RSV infections in under 3-year-old patients admitted to the Inpatient Paediatric Service of Vila Real (North of Portugal). For this purpose, (1) clinical files of children admitted with a diagnosis of acute bronchiolitis from September 2005 to December 2015 (>10 years) were scrutinised and (2) local daily temperature/precipitation series, as well as six weather types controlling meteorological conditions in Portugal, were used. Fifty-five percent of all 770 admitted children were effectively infected with a given virus, whilst 48 % (367) were RSV+, i.e. 87 % of virus-infected children were RSV+. The bulk of incidence is verified in the first year of age (82 %, 302), slightly higher in males. RSV outbreaks are typically from December to March, but important inter-annual variability is found in both magnitude and shape. Although no clear connections were found between monthly temperatures/precipitation and RSV outbreaks apart from seasonality, a linkage to wintertime cold spells is apparent on a daily basis. Anomalously low minimum temperatures from the day of admittance back to 10 days before are observed. This relationship is supported by anomalously high occurrences of the E and AA weather types over the same period, which usually trigger dry and cold weather. These findings highlight some predictability in the RSV occurrences, revealing potential for modelling and risk assessments.

    Atmospheric forecasting and predictability are important to promote adaption and mitigation measures in order to minimize drought impacts. This study estimates hybrid (statistical-dynamical) long-range forecasts of the regional drought index SPI (3-months) over homogeneous regions from mainland Portugal, based on forecasts from the UKMO operational forecasting system, with lead-times up to 6 months. ERA-Interim reanalysis data is used for the purpose of building a set of SPI predictors integrating recent past information prior to the forecast launching. Then, the advantage of combining predictors with both dynamical and statistical background in the prediction of drought conditions at different lags is evaluated. A two-step hybridization procedure is performed, in which both forecasted and observed 500 hPa geopotential height fields are subjected to a PCA in order to use forecasted PCs and persistent PCs as predictors. A second hybridization step consists on a statistical/hybrid downscaling to the regional SPI, based on regression techniques, after the pre-selection of the statistically significant predictors. The SPI forecasts and the added value of combining dynamical and statistical methods are evaluated in cross-validation mode, using the R2 and binary event scores. Results are obtained for the four seasons and it was found that winter is the most predictable season, and that most of the predictive power is on the large-scale fields from past observations. The hybridization improves the downscaling based on the forecasted PCs, since they provide complementary information (though modest) beyond that of persistent PCs. These findings provide clues about the predictability of the SPI, particularly in Portugal, and may contribute to the predictability of crops yields and to some guidance on users (such as farmers) decision making process.

    Stray cats live in high-density colonies in urban areas and pose a health hazard to household cats and humans. In Portugal, information on the parasitic fauna of stray cats is limited and relies mostly on results from faecal analysis. The present survey aimed to determine the prevalence, diversity and intensity of parasites in stray cats from the urban area of Lisbon by means of parasitological necropsy. Internal organs were collected from 162 cats captured in different areas of the city and systematically subjected to parasitological dissection. Helminths were identified by macro- and microscopic examination and protozoa by faecal floatation and sedimentation techniques. The overall prevalence of parasites was 90.7% (95% confidence interval (CI): 85.3-94.6%). A total of 12 parasite species was recorded: Cystoisospora felis (14.2%), Cystoisospora rivolta (46.3%), Sarcocystis sp. (1.2%), Ancylostoma tubaeforme (19.1%), Toxocara cati (38.3%), Ollulanus tricuspis (30.9%), Aelurostrongylus abstrusus (12.4%), Eucoleus aerophilus (0.6%), Taenia taeniaeformis (3.1%), Dipylidium caninum (53.1%), Joyeuxiella pasqualei (15.4%) and Diplopylidium nölleri (3.7%). Overall mean species richness was 2.36 ±  1.52. Helminth mean intensity was highest for O. tricuspis (285.8), followed by D. caninum (42.4), J. pasqualei (14.4), A. tubaeforme (8.1) and T. cati (5.9). The prevalence and variety of parasites found in our sampling are substantially higher than the numbers previously reported in Portugal. Some of the parasites, including T. cati and A. tubaeforme, are zoonotic, which emphasizes the need for parasite control strategies based on demographic containment of stray cat populations in urban areas to promote public health protection.

    Miranda do Douro, located in the northeastern region of Portugal, has notable characteristics not only from a geographic or naturalistic point of view, but also from a cultural perspective. A remarkable one is the coexistence of two different languages: Portuguese and Mirandese, the second being an Astur-Leonese dialect. The current persistence of the Astur-Leonese dialect in this population falls on the singularity of the region: relative isolation, implying difficulties to communicate with other Portuguese regions, while the same location facilitated the establishment of social and commercial relationships with adjacent Spanish territories, origin of the Astur-Leonese language. The objective of this study was to characterize the population from Miranda through the analysis of maternal lineages in order to evaluate whether its mitochondrial DNA diversity fitted the patterns previously reported for other populations from the Iberian Peninsula. Viewing that, the entire control region of mitochondrial DNA from 121 individuals was examined. Miranda showed a haplogroup composition usual for a Western European population, in the sense that as high as 63.6% of sequences belonged to macro-haplogroup R0. Lineages ascribed to have an African (L2a and L1b) origin, were detected, but reaching an amount commonly found in Portugal. Miranda also presented a few haplogroups typically found in Jewish populations, while rarely observed in other Iberian populations. The finding can be explained by gene flow with crypto-Jew communities that since long are known to be established in the region where Miranda is located. In Miranda, both genetic and nucleotide diversities presented low values (0.9292 ± 0.0180 and 0.01101 ± 0.00614 respectively) when compared to populations from its micro-geographical framework, which constitute a sign of population isolation that certainly provided conditions for the survival of the Astur-Leonese dialect in the region.

    Full Text Available El presente estudio analiza la introducción del jujutsu en Portugal, sucedida a principios del siglo XX. Para su realización se ha consultado fundamentalmente prensa histórica portuguesa, tanto general como específica del ámbito deportivo. Los resultados obtenidos muestran que la introducción del jujutsu en Portugal se produjo fundamentalmente a través del mundo del espectáculo, mediante actuaciones de expertos japoneses. Las notables diferencias técnicas y corporales entre estos luchadores japoneses y los luchadores profesionales de lucha libre y grecorromana de la época, a los que habitualmente solían derrotar, contribuyeron a generar un potente imaginario de las artes de combate orientales como sistemas superiores de cultura física y defensa personal. No obstante, a pesar del éxito del jujutsu este no logró afianzarse sólidamente en Portugal, desapareciendo progresivamente de la escena pública desde principios de la segunda década del siglo XX.-------------------------------------------------------------------------------The present study analyzes the introduction of jujutsu in Portugal at the beginning of the 20th century. Mainly, historical Portuguese newspapers were reviewed, both general and specific from sports field. Results show that the introduction of jujutsu in Portugal was principally conduced via the show business through exhibitions performed by Japanese experts. Significant technical and physical differences between the Japanese fighters and the professional Freestyle and Greco-roman fighters, who were usually defeated by the former, contributed to create a powerful imaginary of the eastern fighting arts as superior systems of physical culture and self-defence. However, in spite of jujutsu’s success, it did not come to be strongly established in Portugal, vanishing progressively off the public scene since the beginning of the 1910s.

    Full Text Available In the specific case of the quince trees, there is lack of information about the emergency of their seedlings, development and time of production of rootstocks to reach the point of the grafting, as well as development of the grafts. Therefore, the objective of the present research was to study the Cydonia and Chaenomeles genera, as well as the development of the grafts during the nursery phase. Seeds of the quince tree cultivars 'Mendoza Inta-37', 'Provence', ' Portugal' and 'Japonês' were obtained from ripe fruits and submitted to cold stratification during 20 days. Soon after, the seeds were sowed in 72-cell polystyrene trays (120 cm³ of capacity/cell containing vermiculite as substrate. After 60 days, the seedlings were put in plastic bags (3 liters of capacity filled with a substrate containing soil: sand: manure (1:1:1 v/v. The seedlings were kept in a 50% of shadow nursery and periodically irrigated. After 180 days, the seedlings were grafted by the cleft grafting method, during the winter, using scion sticks from quince 'Portugal'. After 60 days, the percentage of alive and sprouted grafts was evaluated. The length and diameter of the grafts were measured every 30 days, a total of four times. The quince 'Japonês' showed the best performance among all the rootstocks in this experiment, being an excellent alternative as rootstock for quince trees. 'Japonês' and 'Mendoza Inta-37' were also the rootstocks that promoted the best development of the grafts.Com relação ao marmeleiro, há carência de informações sobre a emergência das plântulas, desenvolvimento e tempo de produção dos porta-enxertos, assim como o desenvolvimento do enxerto.

    Initial drilling of wells on a uniform spacing, without regard to reservoir performance and characterization, must become a process of the past. Such efforts do not optimize reservoir development as they fail to account for the complex nature of reservoir heterogeneities present in many low permeability reservoirs, and carbonate reservoirs in particular. These reservoirs are typically characterized by: o Large, discontinuous pay intervals o Vertical and lateral changes in reservoir properties o Low reservoir energy o High residual oil saturation o Low recovery efficiency

Neste contexto, a comunidade brasileira assumiu uma importância cada vez maior, sendo em 2009 a nacionalidade mais representada, com uma participação de 25% no total de residentes estrangeiros em Portugal. Esta evolução tem, como seria de se esperar, reflexos a outros níveis, em particular no contexto do casamento. Contrariando a tendência decrescente observada para o total de casamentos ocorridos entre 2001 e 2009, aqueles em que pelo menos um dos cônjuges nasceu no Brasil quase quadruplicaram nesse período. Para muitos autores, os casamentos mistos são um bom indicador da integração das comunidades imigrantes na sociedade de acolhimento. Assim, dada a importância da comunidade brasileira residente em Portugal, é relevante observar qual o peso dos casamentos mistos nesta comunidade e analisar seus padrões de matrimônio. A análise estatística dos microdados dos casamentos disponibilizados pelo Instituto Nacional de Estatística possibilitou estudar e caraterizar a evolução dos casamentos registrados em Portugal, entre 2001 e 2009, envolvendo brasileiros residentes em Portugal. Ficou patente a existência de um elevado nível de casamentos mistos, em especial com portugueses, neste período, o que indicia sua integração na comunidade de acolhimento.

  12. Unconventional Reservoirs: Ideas to Commercialization

    There is no shortage of coal, oil, and natural gas in the world. What are sometimes in short supply are fresh ideas. Scientific innovation combined with continued advances in drilling and completion technology revitalized the natural gas industry in North America by making production from shale economic. Similar advances are now happening in shale oil. The convergence of ideas and technology has created a commercial environment in which unconventional reservoirs could supply natural gas to the North American consumer for 50 years or more. And, although not as far along in terms of resource development, oil from the Eagle Ford and Bakken Shales and the oil sands in Alberta could have a similar impact. Without advanced horizontal drilling, geosteering, staged hydraulic-fracture stimulation, synthetic and natural proppants, evolution of hydraulic fluid chemistry, and high-end monitoring and simulation, many of these plays would not exist. Yet drilling and completion technology cannot stand alone. Also required for success are creative thinking, favorable economics, and a tolerance for risk by operators. Current understanding and completion practices will leave upwards of 80% of oil and natural gas in the shale reservoirs. The opportunity to enhance recovery through advanced reservoir understanding and imaging, as well as through recompletions and infill drilling, is considerable. The path from ideas to commercialization will continue to provide economic results in unconventional reservoirs.

  13. Reservoir Oscillations with Through Flow

    Directory of Open Access Journals (Sweden)

    A. A. Khan

    2007-01-01

    Full Text Available The two-reservoir problem with through flow is a common feature in wastewater treatment plants. The start of the through flow may cause water surface oscillations in the reservoirs and velocity variations in the connecting pipe during the initial unsteady phase that may adversely affect the operation and under certain conditions may cause overtopping of the upstream reservoir. The classical solution based on the rigid mass theory is inapplicable as velocity variations within the pipe system are ignored. One-dimensional mass and momentum conservation equations, based on the elastic theory, with a new set of boundary conditions are solved using the method of characteristics to investigate the water surface oscillations in the two reservoirs and minimum velocity in the connecting pipe as a result of the start of a through flow. The impact of a constant or variable friction factor on the velocity and water surface oscillations in the connecting pipe is found to be negligible. The magnitude and the time it takes to establish the through flow are found to be important parameters for the system. Optimum time of linear increase of a given inflow rate to the final steady state discharge is investigated for an actual facility. A ramp time of 40 seconds is found to reduce the maximum water surface level from 40 cm to 9.4 cm and increase the minimum velocity in the system to 85% of the final steady state velocity.

  17. Iberian lynx conservation in Portugal: dilemmas and solutions

    Sarmento, P.

    2005-12-01

    Full Text Available Ateam of biologists and field assistants conducted, between January 2002 and May 2003, a survey on the status of the Iberian lynx in Portugal. The survey was performed on previously identified lynx areas, during studies carried out in the 1970-s and 1990-s Intensive search for lynx scats, for DNA analysis, and camera trapping provided a basis for identifying potential lynx areas. Over 4200 km were covered during a global searching effort of 1975 man-hours. This effort resulted in the collection of 168 potential scats that were submitted to genetic validation with no positive lynx amplifications. Camera trapping was applied in a total effort of 5647 camera days, in three lynx potential areas. No positive detections were achieved. At the same time, a study on wild rabbit distribution reveals that most historical nuclei do not support lynx viable populations. Although we can not confirm extinction, the scenario is highly pessimistic. The Iberian lynx is presently in the verge of extinction. Intensive rabbit regression and massive habitat destruction are identified as the main causes of decline in recent decades. In the Portuguese lynx historical range, we could only identify significant areas suitable for lynx in the South-eastern part of the country, particularly in the Andalusian border, where we lack on recent evidence of lynx presence. Being aware of the considerable difficulties pointed above, the ICN developed a Conservation Action Plan for the Iberian lynx in order to provide a consistent and effective approach to conserve the species in Portuguese territory. This proposal describes guidance that retains future options, provides management consistent, offers necessary flexibility, in order to achieve the maximum goal of conserving the lynx in Portugal. Conservation measures have the goal of provide guiding lines for conservations agents in order to conduct actions that can positively affect lynx and/or to help avoid negative impacts through

    Amplitude various offset is widely used in petroleum exploration as well as in petroleum development field. Generally, phenomenon of amplitude in various angles assumes reservoir’s layer is quite thick. It also means that the wave is assumed as a very high frequency. But, in natural condition, the seismic wave is band limited and has quite low frequency. Therefore, topic about amplitude various angles in thin layer reservoir as well as low frequency assumption is important to be considered. Thin layer reservoir means the thickness of reservoir is about or less than quarter of wavelength. In this paper, I studied about the reflection phenomena in elastic wave which considering interference from thin layer reservoir and transmission wave. I applied Zoeppritz equation for modeling reflected wave of top reservoir, reflected wave of bottom reservoir, and also transmission elastic wave of reservoir. Results show that the phenomena of AVA in thin layer reservoir are frequency dependent. Thin layer reservoir causes interference between reflected wave of top reservoir and reflected wave of bottom reservoir. These phenomena are frequently neglected, however, in real practices. Even though, the impact of inattention in interference phenomena caused by thin layer in AVA may cause inaccurate reservoir characterization. The relation between classes of AVA reservoir and reservoir’s character are different when effect of ones in thin reservoir and ones in thick reservoir are compared. In this paper, I present some AVA phenomena including its cross plot in various thin reservoir types based on some rock physics data of Indonesia.

  6. Radiation protection in Portugal: health, safety and legal aspects

    International Nuclear Information System (INIS)

    The paper describes the basic legal and technical principles governing radiation protection in Portugal. The methods used in the medical surveillance of occupationally exposed persons (especially in the assessment of biological effects) are described and the results of recent studies carried out with a view to improving biological dosimetry techniques are reported. An account is also given of dosimetry at nuclear centres in mines, at research establishments, in industry and in hospitals and private clinics, the accumulated doses being examined in the light of international recommendations relating to radiation protection. Statistical data on the granting of licences to different kinds of establishment are considered from the radiation safety point of view by the authors, who also describe the methods used for controlling waste from nuclear facilities and the measures taken in such special situations as the visit of a nuclear-powered ship to a Portuguese port or the disposal of radioactive waste into the Atlantic Ocean. A brief account is given of recent efforts to check on radioactive pollution (especially the contamination of milk by 90Sr). Lastly, the criteria followed in licensing and controlling Portuguese establishments which work with radioactive substances or other radiation sources are reviewed and, on the basis of experience, a critical appraisal is made of the application of the fundamental technical and legal principles, which presupposes the necessary co-operation between license-issuing authority, facility operator and staff

  7. Salt fluxes in a complex river mouth system of Portugal.

    Directory of Open Access Journals (Sweden)

    Nuno Vaz

    Full Text Available Measurements of velocity and salinity near the mouth and head of the Espinheiro channel (Ria de Aveiro lagoon, Portugal are used to study the local variation of physical water properties and to assess the balance, under steady conditions, between the seaward salt transport induced by river discharge and the landward dispersion induced by various mixing mechanisms. This assessment is made using data sampled during complete tidal cycles. Under the assumption that the estuarine tidal channel is laterally homogeneous and during moderate tidal periods (except for one survey, currents and salinity data were decomposed into various spatial and temporal means and their deviations. Near the channel's mouth, the main contributions to the salt transport are the terms due to freshwater discharge and the tidal correlation. Near the channel's head, this last term is less important than the density driven circulation, which is enhanced by the increase in freshwater discharge. The remaining terms, which are dependent on the deviations from the mean depth have a smaller role in the results of salt transport. The computed salt transport per unit width of a section perpendicular to the mean flow is in close agreement to the sum of the advective and dispersive terms (within or very close to 12%. An imbalance of the salt budget across the sections is observed for all the surveys. Considerations are made on how this approach can inform the management of hazardous contamination and how to use these results to best time the release of environmental flows during dry months.

    Full Text Available The main goal of this study is to analyse the most important causes affecting fire ignitions in Portugal mainland, between 1996 and 2010. The forest fire database was provided by the Portuguese Government Forest Services (National Forest Authority, AFN, that group the causes in six main categories (negligent usage of fire, accidental, structural causes, incendiary, natural and unknown.The analysis of the causes of the forest fires ignitions shows that the greatest part was not investigated (84%, whilst the knowledge of cause only occurred in 8% of fires. At national level, the results show that incendiary and the negligent usage of the fire are the most important motivations behind forest fires, with almost 40% of the identified causes. At regional scale, fires caused by negligence seems to be more common in the north due to traditional agricultural practices such as pasture renewal, the burning of agricultural and forest debris and hunting practices. In the Alentejo, accidental causes mainly associated with crop harvesting machinery, were the primary reason for the outbreak of forest fires.

    Ticks are ubiquitous arthropods and vectors of several pathogenic agents in animals and humans. Monitoring questing ticks is of great importance to ascertain the occurrence of pathogens and the potential vector species, offering an insight into the risk of disease transmission in a given area. In this study 428 host-seeking ticks, belonging to nine species of Ixodidae and collected from 17 of the 23 Portuguese mainland subregions, were screened for several tick-borne agents with veterinary relevance: Anaplasma marginale, Anaplasma ovis, Anaplasma centrale, Babesia spp., Coxiella burnetii and Theileria spp. Prevalence was assessed by PCR and amplified amplicons sequenced for validation of results. Twenty ticks, in a total of 428, were found positive: one Ixodes ventalloi for Theileria annulata and four Dermacentor marginatus, one Haemaphysalis punctata, five Ixodes ricinus, five I. ventalloi, and four Rhipicephalus sanguineus sensu lato for A. marginale. According to the reviewed literature, this is the first report of A. marginale and T. annulata detection in I. ventalloi. Furthermore, the amplification of A. marginale DNA in several tick species suggests a broad range for this agent in Portugal that might include other uncommon species as R. sanguineus s.l. This work provides new data towards a better understanding of tick-pathogen associations and also contributes to the surveillance of tick-borne agents in geographic areas with limited information.

    Marine litter is of global concern and is present in all the world's oceans, including deep benthic habitats where the extent of the problem is still largely unknown. Litter abundance and composition were investigated using video footage and still images from 16 Remotely Operated Vehicle (ROV) dives in Lisbon, Setúbal, Cascais and Nazaré Canyons located west of Portugal. Litter was most abundant at sites closest to the coastline and population centres, suggesting the majority of the litter was land sourced. Plastic was the dominant type of debris, followed by fishing gear. Standardised mean abundance was 1100 litter items km -2, but was as high as 6600 litter items km -2 in canyons close to Lisbon. Although all anthropogenic material may be harmful to biota, debris was also used as a habitat by some macro-invertebrates. Litter composition and abundance observed in the canyons of the Portuguese margin were comparable to those seen in other deep sea areas around the world. Accumulation of litter in the deep sea is a consequence of human activities both on land and at sea. This needs to be taken into account in future policy decisions regarding marine pollution.

    2009-05-01

    Although, recently, the biopsychosocial approach has been emphasized in the practice of family medicine, how psychologists and physicians interact in collaborative family health care practice is still emerging in Portugal. This article describes a qualitative study that focused on the understanding of psychologists and family physicians' perceptions of their role and the collaborative approach in health care. A questionnaire gathered information regarding collaboration, referral, training and the practice of biopsychosocial medicine. A content analysis on respondents' discourse was performed. Results show that both physicians and psychologists agree on the importance of the biopsychosocial model and interdisciplinary collaboration. However, they also mentioned several difficulties that have to do with the lack of psychologists working full time in health care centers, lack of communication and different expectancies regarding each other roles in health care delivery. Both physicians and psychologists acknowledge the lack of academic training and consider the need for multidisciplinary teams in their training and practice to improve collaboration and integrative care. Implications for future research and for the practice of biopsychosocial medicine are addressed. PMID:19476234

    A Turkish-Austrian Consortium is constructing the hydro power plant Ermenek in Turkey. Client of this project is the Turkish State Hydraulic Works, DSI. The project consists of a double curved arch dam, a large grout curtain, a pressure tunnel, a power house and appurtenant structures. The arch dam is ideally located in a narrow gorge, with a natural width at the base of 20 m and at the crest of 110 m, with an entire dam height of 218 m and a concrete volume of 290 000 m{sup 3}. The concreting works for the dam started on 6{sup th} September 2007 and were finished by 20{sup th} October 2009. As the reservoir has an overall volume of about 4 600 million m{sup 3} the impounding started during the construction. Within a very short time the reservoir level has increased up to 70 m above foundation. The entire dam safety concept is discussed. (orig.)

    Full Text Available The preparation of music teachers in Portugal and Brazil is the focus of this text, which aims at presenting preliminary aspects of a study in progress in the context of higher education in both countries. Inspired by comparative education methodology, the present study is investigating official documents and academic curricula offered in Portugal and Brazil for the music teachers’ preparation to promote, in different ways, the comparative reflection with an emphasis on school education. The music teachers’ education in both countries was analyzed taking into account the following elements: educational context in Portugal and Brazil; music preparation prior to higher education, and the entrance criteria in the courses that are offered for music teachers; curricular elements of the courses; teaching practice and professional perspectives. The preliminary results of this comparative analysis demonstrate similarities and differences in the two contexts: 1 in both countries, music teachers for regular schools receive their degrees in higher education institutions, and in Portugal, beyond the Licenciatura in Music, a Music Education Master degree is demanded; 2 in both countries specific entrance tests are accomplished in the universities, demanding previous musical knowledge; 3 the balance among the musical and pedagogical preparation is one of the curricular objectives; 4 the teaching practice is an emphasized component in the teachers’ preparation; 5 in Portugal, student’s motivation for the work in the regular school appears to be larger than in Brazil.

  17. The role of reservoir characterization in the reservoir management process (as reflected in the Department of Energy`s reservoir management demonstration program)

    Optimum reservoir recovery and profitability result from guidance of reservoir practices provided by an effective reservoir management plan. Success in developing the best, most appropriate reservoir management plan requires knowledge and consideration of (1) the reservoir system including rocks, and rock-fluid interactions (i.e., a characterization of the reservoir) as well as wellbores and associated equipment and surface facilities; (2) the technologies available to describe, analyze, and exploit the reservoir; and (3) the business environment under which the plan will be developed and implemented. Reservoir characterization is the essential to gain needed knowledge of the reservoir for reservoir management plan building. Reservoir characterization efforts can be appropriately scaled by considering the reservoir management context under which the plan is being built. Reservoir management plans de-optimize with time as technology and the business environment change or as new reservoir information indicates the reservoir characterization models on which the current plan is based are inadequate. BDM-Oklahoma and the Department of Energy have implemented a program of reservoir management demonstrations to encourage operators with limited resources and experience to learn, implement, and disperse sound reservoir management techniques through cooperative research and development projects whose objectives are to develop reservoir management plans. In each of the three projects currently underway, careful attention to reservoir management context assures a reservoir characterization approach that is sufficient, but not in excess of what is necessary, to devise and implement an effective reservoir management plan.

    It is important to investigate the coalbed methane reservoir boundaries for the classification, exploration, and development of the coalbed methane reservoir.Based on the investigation of the typical coalbed methane reservoirs in the world, the boundaries can be divided into four types: hydrodynamic boundary, air altered boundary,permeability boundary, and fault boundary. Hydrodynamic and air altered boundaries are ubiquitous boundaries for every coalbed methane reservoir. The four types of the fault sealing mechanism in the petroleum geological investigation (diagen- esis, clay smear, juxtaposition and cataclasis) are applied to the fault boundary of the coalbed methane reservoir. The sealing mechanism of the open fault boundary is the same with that of the hydrodynamic sealing boundary.The sealing mechanism of the permeability boundary is firstly classified into capillary pressure sealing and hydrocarbon concentration sealing. There are different controlling boundaries in coalbed methane reservoirs that are in different geological backgrounds. Therefore, the coalbed methane reservoir is diversiform.

    2003-12-01

    We have developed and tested technology for a new type of direct hydrocarbon detection. The method uses inelastic rock properties to greatly enhance the sensitivity of surface seismic methods to the presence of oil and gas saturation. These methods include use of energy absorption, dispersion, and attenuation (Q) along with traditional seismic attributes like velocity, impedance, and AVO. Our approach is to combine three elements: (1) a synthesis of the latest rock physics understanding of how rock inelasticity is related to rock type, pore fluid types, and pore microstructure, (2) synthetic seismic modeling that will help identify the relative contributions of scattering and intrinsic inelasticity to apparent Q attributes, and (3) robust algorithms that extract relative wave attenuation attributes from seismic data. This project provides: (1) Additional petrophysical insight from acquired data; (2) Increased understanding of rock and fluid properties; (3) New techniques to measure reservoir properties that are not currently available; and (4) Provide tools to more accurately describe the reservoir and predict oil location and volumes. These methodologies will improve the industry's ability to predict and quantify oil and gas saturation distribution, and to apply this information through geologic models to enhance reservoir simulation. We have applied for two separate patents relating to work that was completed as part of this project.

  5. Beyond the “Casa Portuguesa”: analysis of popular music exchanges between Brazil and Portugal

    Directory of Open Access Journals (Sweden)

    Tiago José Lemos Monteiro

    2008-12-01

    Full Text Available This paper identifies and discusses the silences and the asymmetrical relations that characterize the exchanges of popular music between Brazil and Portugal. At the same time that our perception of the contemporary Portuguese culture seems mediated by a "mythical common sense" deeply influenced by the discourse of tradition, Portugal became an enthusiastic consumer of our "modern" media culture. Such assymetries are visible in the huge success of Brazilian artists and bands in Portugal, whose counterpoint is the absence of Portuguese contemporary musical production in Brazil, especially those related to pop/rock. This paper aims to question the socially constructed nature of such speeches, and thus contribute to the elucidation of some aspects of local-global dynamics in the industry of entertainment, related to the musical consumption practices of the urban youth.

    Full Text Available This paper aims to look at the teaching situation of the nursing undergraduate degree’s courses about eldercare in Portugal. A documentary research on the teaching programs in 39 nursing schools, 26 schools presented syllabus units related to the topic ‘eldercare’ and in eight of these schools the contents of the units were identified. Using textual analysis and from the categories we concluded that the teaching regarding eldercare for the nurse training in Portugal is focused on hospital care; it is directed to the adult/elderly/family; it explores the definitions related to the aging process; it explores community issues, legislation and research. People responsible for the design/monitoring of teaching programs should include teaching regarding eldercare in the nurse training, considering that the elder population is increasing in Portugal.

Em 1997, viviam em Portugal 175.263 pessoas com autorização de residência, a que se juntavam imigrantes ilegais em número desconhecido, calculando-se em pouco mais de 2% a percentagem de imigrantes no cômputo total da população residente no país. 11,4% dos imigrantes eram oriundos do Brasil. Dados mais recentes e ainda provisórios, fornecidos pelo Serviço de Estrangeiros e Fronteiras, relativos a 2007, dão conta de 435.736 imigrantes legais. Os brasileiros, num total de 66.354, representam 15,2% desse total. Sabendo-se que a presença de uma comunidade estrangeira numericamente significativa dá origem quer à abertura de pequenas lojas de produtos antes inexistentes no país de acolhimento quer ao comércio paralelo, procurei sondar que novidades alimentares brasileiras ocorreram em Portugal nos últimos anos, através de um questionário a realizar a um mínimo de 200 brasileiros. Pretendeu saber-se sexo, idade, estado de onde são oriundos, atividade a que se dedicam, prato brasileiro preferido, quais os alimentos que consumiam no Brasil e não conseguem encontrar em Portugal, quais os alimentos brasileiros que consomem em Portugal e, finalmente, onde conseguem obtê-los. A análise dos dados obtidos no questionário, bem como as informações disponíveis acerca dos chamados restaurantes étnicos, permitem estudar os hábitos alimentares da comunidade brasileira em Portugal, nomeadamente as transmissões, recepções e transformações alimentares que estão em curso e que têm repercussões entre portugueses e brasileiros, uma vez que as transferências culturais resultam das inter-relações entre conjuntos culturais postos em contacto.From 1993 onwards the net migratory balance in Portugal has become positive and on the rise.

  10. Does Trade Help to Explain Tourism Demand? The Case of Portugal

    Directory of Open Access Journals (Sweden)

    Nuno Carlos LEITÃO

    2010-03-01

    Full Text Available The tourism industry has expanded in recent years due to internal and external environmental forces. These forces, income, trade, consumer price, and geographical distance are interconnected. Accounting for imperfect competition and increasing returns to scale, the new trade theory offers the explanation of dynamic gains from international trade. A large number of studies attempt to test the hypothesis that there is a link between trade and tourism. Most of the studies show that trade and tourism are positively correlated. This paper specifies static and dynamic panel demand models for tourism in Portugal and estimates demand equations using tourist inflow data for the period 1995-2006. We find that bilateral trade, immigration, border, and geographical distance between Portugal and countries of origin are the main determinants of tourism to Portugal. The dynamic panel data approach indicates that trade, population, and income are more important determinants than relative price.

    Full Text Available Sea urchins play a key role structuring benthic communities of rocky shores through an intense herbivory. The most abundant sea urchin species on shallow rocky subtidal habitats of the SW coast of Portugal is Paracentrotus lividus (Echinodermata: Echinoidea. It is considered a key species in various locations throughout its geographical distribution by affecting the structure of macroalgae communities and may cause the abrupt transformation of habitats dominated by foliose algae to habitats dominated by encrusting algae - the urchin barrens. The removal of P. lividus predators by recreational and commercial fishing is considered a major cause of this phenomenon by affecting the trophic relationships between predators, sea urchins and algae communities. Marine protected areas (MPAs usually lead to the recovery of important predator species that control sea urchin populations and restore habitats dominated by foliose macroalgae. Therefore, MPAs provide a good opportunity to test cascading effects and indirect impacts of fishing at the ecosystem level. The ecological role of P. lividus was studied on rocky subtidal habitats of the SW coast of Portugal (Alentejo considering three trophic levels: population of P. lividus, their predators (fish and shellfish and their prey (macroalgae communities. Several studies were conducted: (1 a non-destructive observational study on the abundance and distribution patterns of P. lividus, their predators and preys, comparing areas with different protection; (2 a manipulative in situ study with cages to assess the role of P. lividus as an herbivore and the influence of predation; (3 a descriptive study of P. lividus predators based on underwater filming; (4 and a study of human perception on these trophic relationships and other issues on sea urchin ecology and fishery, based on surveys made to fishermen and divers. Subtidal studies were performed with SCUBA diving at 3-12 m deep. Results indicate that in the

  13. The impact of winter cold weather on acute myocardial infarctions in Portugal

    International Nuclear Information System (INIS)

    Mortality due to cardiovascular diseases shows a seasonal trend that can be associated with cold weather. Portugal is the European country with the highest excess winter mortality, but nevertheless, the relationship between cold weather and health is yet to be assessed. The main aim of this study is to identify the contribution of cold weather to cardiovascular diseases within Portugal. Poisson regression analysis based on generalized additive models was applied to estimate the influence of a human-biometeorological index (PET) on daily hospitalizations for myocardial infarction. The main results revealed a negative effect of cold weather on acute myocardial infarctions in Portugal. For every degree fall in PET during winter, there was an increase of up to 2.2% (95% CI = 0.9%; 3.3%) in daily hospital admissions. This paper shows the need for public policies that will help minimize or, indeed, prevent exposure to cold. -- Highlights: ► We model the relationship between daily hospitalizations due to myocardial infarctions and cold weather in Portugal. ► We use Physiological Equivalent temperature (PET) as main explanatory variable. ► We adjust the models to confounding factors such as influenza and air pollution. ► Daily hospitalizations increased up to 2.2% per degree fall of PET during winter. ► Exposure to cold weather has a negative impact on human health in Portugal. -- There is an increase of up to 2.2% in daily hospitalizations due to acute myocardial infarctions per degree fall of thermal index during the winter months in Portugal

    2016-04-01

    Earth construction is the oldest building material known, with documented cases of the use of earth bricks since Mesopotamia around 10 000 BC (Heathcote, 1995). The earth construction exists throughout the majority of the world in different cultures, and for some countries, nowadays it continues to be the main process of construction (Vega et al, 2011). Around 30% of the world's population lives in buildings made of earth materials. Earthen construction is an environmentally friendly technique with a social and cultural contribution; this advantage is increased when this type of construction is applied in developing countries where the material costs counterbalance with labour costs, and where other materials and techniques cannot be available (Ciancio et al, 2013). Studies of materials characterization are required in order to understand the composition and specific properties of the earth buildings, their heterogeneity and their degradation mechanisms. Some adobes from different buildings, ages and regions of Portugal were collected in order to characterize them (mineralogically, chemically and physically). It was possible to understand the composition of these materials and their differences. Main minerals are quartz, feldspars, calcite and phyllosilicates (mica and kaolinite). The mechanical behaviour of these materials isn't the best, but it is possible to improve it with some simple and cheap natural additives (kaolinitic soils). The characterization of these materials allows us to understand the differences between the materials from the different regions (controlled by locally available raw materials). Understanding these materials, and their properties, it is possible to formulate new ones for repair, conservation and rehabilitation works. The adobe bricks are an alternative of kiln baked bricks which has several advantages and one of the most important is that these materials are recyclable. Adobes are an excellent option for building rehabilitation, if

    Full Text Available Les réformes éducatives réalisées par le marquis de Pombal (1699-1782 au milieu du xviiie siècle sont généralement considérées comme un des moments critiques dans la genèse d’une politique scientifique moderne au Portugal. À la suite de l’expulsion de la Compagnie de Jésus (1759, la structure de l’enseignement secondaire et pré-universitaire a été radicalement transformée. Avec la réforme de l’Université (1772, la définition même d’enseignement supérieur et le rôle de l’université ont été profondément altérés. Le programme réformateur de Pombal était explicitement modernisateur (introduction des sciences expérimentales, création d’une Faculté de mathématiques, abandon du latin, etc., et il a été conduit avec la détermination de la personnalité excessive du célèbre marquis. Mais en dépit de l’indéniable modernité de cet ambitieux projet, les actions de Pombal étaient aussi très influencées par des contraintes politiques et une vision particulière du rôle de la science dans la société. Le résultat final, selon plusieurs historiens, a été extrêmement complexe, voire paradoxal.

  17. Occurrence of persistent organic pollutants in sediments and biota from Portugal versus European incidence: A critical overview.

    Persistent organic pollutants (POPs) are widespread compounds, such as organohalogenated compounds, polycyclic aromatic hydrocarbons (PAHs) and pesticides, which can be found in all types of environmental compartments. Their presence in the aquatic environment is a worldwide problem, with emphasis on sediments which act as depository and consequently as a source of hydrophobic, recalcitrant and harmful compounds. Besides, these pollutants might affect the reproduction and mortality of living organisms, diverging in their potential to bioaccumulate in tissues. The present paper aims to review the occurrence of POPs in sediments and biota from the coastal, estuarine and river areas of Portugal. The list of the studied compounds comprises organohalogenated compounds, PAHs, organometallic compounds, pesticides, sterols, fatty acids and pharmaceutical compounds. The contamination of sediments by various pollutants is presented, such as PAHs up to 7,350 ng g(-1) found in Sado estuary and polychlorinated biphenyls up to 62.2 ng g(-1) in the case of sediments collected in Ria de Aveiro. The occurrence of these persistent toxic substances in sediments demonstrates aquatic contamination from agricultural, industrial and urban discharges and the concern about the potential risks to aquatic organisms, wildlife and humans. In fact, several classes of POPs have also been found in biota, such as polychlorinated biphenyls up to 810.9 ng g(-1) in sentinel fish from the Douro River estuary and pesticides in bivalves from the Sado River estuary. The importance of further systematic research on sediments and biota is here highlighted to compare the contamination of these two reservoirs; to assess their spatial and temporal variation; and to determine other classes of POPs that were not investigated yet (e.g., industrial compounds, estrogens and many classes of pharmaceuticals).

    Although eradicated in Portugal, malaria keeps taking its toll on travellers and migrants from endemic countries. Completeness of hospital requiring malaria notification in Portugal 2000-11 was estimated, using two-source capture-recapture method. Data sources were: national surveillance database of notifiable diseases and the national database of the Diagnosis-Related Groups resulting from National Health Service (NHS) hospital episodes. The completeness of notification was 21,2% for all malaria cases and 26,5% for malaria deaths, indicating significant underreporting and urging for complementary data source in surveillance, for disease burden estimates and retrospective monitoring, namely hospital episodes statistics.

This consolidation process ends with the emergency of school subjects that develop some kind of autonomy as Chervel puts it. This article discusses how the school discipline of mathematics in secondary education in Portugal was set. This process is inseparable from teacher training and so we will observe professional legitimation processes paying special attention to ways in which autonomy has been building and modifying over time.

    Although eradicated in Portugal, malaria keeps taking its toll on travellers and migrants from endemic countries. Completeness of hospital requiring malaria notification in Portugal 2000-11 was estimated, using two-source capture-recapture method. Data sources were: national surveillance database of notifiable diseases and the national database of the Diagnosis-Related Groups resulting from National Health Service (NHS) hospital episodes. The completeness of notification was 21,2% for all malaria cases and 26,5% for malaria deaths, indicating significant underreporting and urging for complementary data source in surveillance, for disease burden estimates and retrospective monitoring, namely hospital episodes statistics.

    The increased integration of wind power into the electric grid, as nowadays occurs in Portugal, poses new challenges due to its intermittency and volatility. Wind power prediction plays a key role in tackling these challenges. The contribution of this paper is to propose a new hybrid approach, combining particle swarm optimization and adaptive-network-based fuzzy inference system, for short-term wind power prediction in Portugal. Significant improvements regarding forecasting accuracy are attainable using the proposed approach, in comparison with the results obtained with five other approaches. (author)

    2003-11-01

    The zooplankton of 18 reservoirs of South China was investigated in 2000. 61 Rotifera species, 23 Cladoceras and 14 Copepodas were identified. The most frequent Rotifera genera were Keratella, Brachionus, Trichocerca, Diurella, Ascomorpha, Polyarthra, Ploesoma, Asplanchna, Pompholyx and Conochilus. Bosmina longirostris, Bosminopsis deitersi, Diaphanosoma birgei, D. brachyurum and Moina micrura were typical of Cladocera in the reservoirs. Phyllodiaptomus tunguidus, Neodiaptomus schmackeri and Mesocyclops leuckarti were the most frequent Copepoda and M. leuckarti dominated Copepoda in most reservoirs. High zooplankton species richness with low abundance was characteristic of the throughflowing reservoir, whereas low species richness with low abundance was found in the reservoir with the longest retention time. Relative high abundance and medium species diversity were the distinction of intermediate retention time reservoirs.

  14. Data Compression of Hydrocarbon Reservoir Simulation Grids

    KAUST Repository

    Chavez, Gustavo Ivan

    2015-05-28

    A dense volumetric grid coming from an oil/gas reservoir simulation output is translated into a compact representation that supports desired features such as interactive visualization, geometric continuity, color mapping and quad representation. A set of four control curves per layer results from processing the grid data, and a complete set of these 3-dimensional surfaces represents the complete volume data and can map reservoir properties of interest to analysts. The processing results yield a representation of reservoir simulation results which has reduced data storage requirements and permits quick performance interaction between reservoir analysts and the simulation data. The degree of reservoir grid compression can be selected according to the quality required, by adjusting for different thresholds, such as approximation error and level of detail. The processions results are of potential benefit in applications such as interactive rendering, data compression, and in-situ visualization of large-scale oil/gas reservoir simulations.

    1982-01-01

    The ability to evaluate sandstone reservoirs has been greatly improved since the use of electonic computer in processing well log data. But it is still difficult to analyse reservoirs with high water saturation, or reservoirs with high residual oil saturation and aquifers containing oil etc. Based on the studies of the reservoirs and aquifers in respect to their oil saturation, porosity, lithology factor and other independent parameters relative to water invasion and water distribution etc., an optimum discrimination is proposed for the accurate evalation of reservoirs and aquifers using discriminant analysis as a tool. The final recognition is achieved on the electronic computer. This new technique and processing program has been widely tested and verified in the Shengli oil field and other fields in east China, with precision up to 90 percent or more. Now the technique has been extensively applied to the evaluation of Tertiary reservoirs with success.

  16. Production-induced changes in reservoir geomechanics

    Science.gov (United States)

    Amoyedo, Sunday O.

    Sand production remains a source of concern in both conventional and heavy oil production. Porosity increase and changes in local stress magnitude, which often enhance permeability, have been associated with severe sanding. On the other hand, sand production has been linked to a large number of field incidences involving loss of well integrity, casing collapse and corrosion of down-hole systems. It also poses problems for separators and transport facilities. Numerous factors such as reservoir consolidation, well deviation angle through the reservoir, perforation size, grain size, capillary forces associated with water cut, flow rate and most importantly reservoir strain resulting from pore pressure depletion contribute to reservoir sanding. Understanding field-specific sand production patterns in mature fields and poorly consolidated reservoirs is vital in identifying sand-prone wells and guiding remedial activities. Reservoir strain analysis of Forties Field, located in the UK sector of the North Sea, shows that the magnitude of the production-induced strain, part of which is propagated to the base of the reservoir, is of the order of 0.2 %, which is significant enough to impact the geomechanical properties of the reservoir. Sand production analysis in the field shows that in addition to poor reservoir consolidation, a combined effect of repeated perforation, high well deviation, reservoir strain and high fluid flow rate have contributed significantly to reservoir sanding. Knowledge of reservoir saturation variation is vital for in-fill well drilling, while information on reservoir stress variation provides a useful guide for sand production management, casing design, injector placement and production management. Interpreting time-lapse difference is enhanced by decomposing time-lapse difference into saturation, pressure effects and changes in rock properties (e.g. porosity) especially in highly compacting reservoirs.

    We have developed techniques to extract arbitrary fractions of antiprotons from an accumulated reservoir, and to inject them into a Penning-trap system for high-precision measurements. In our trap-system antiproton storage times > 1.08 years are estimated. The device is fail-safe against power-cuts of up to 10 hours. This makes our planned comparisons of the fundamental properties of protons and antiprotons independent from accelerator cycles, and will enable us to perform experiments during long accelerator shutdown periods when background magnetic noise is low. The demonstrated scheme has the potential to be applied in many other precision Penning trap experiments dealing with exotic particles.

    Seeking flexible methods to control quantum teleportation in open systems is an important task of quantum communication. In this paper, we study how the super-Ohmic, Ohmic and sub-Ohmic reservoirs affect teleportation of a general one-qubit state. The results revealed that the structures of the reservoirs play a decisive role on quality of teleportation. Particularly, the fidelity of teleportation may be improved by the strong backaction of the non-Markovian memory effects of the reservoir. T...

  1. Occurrence of springs in massifs of crystalline rocks, northern Portugal

    Pacheco, Fernando António Leal; Alencoão, Ana Maria Pires

    2002-02-01

    An inventory of artesian springs emerging from fractures (fracture springs) was conducted in the Pinhão River Basin and Morais Massif, northern Portugal, comprising an area of approximately 650 km2. Over 1,500 springs were identified and associated with geological domains and fracture sets. Using cross-tabulation analysis, spring distributions by fracture sets were compared among geological environments, and the deviations related to differences in rock structure and, presumably, to differences in deformational histories. The relation between spring frequencies and rock structures was further investigated by spectral determination, the model introduced in this study. Input data are the spring frequencies and fracture lengths in each geological domain, in addition to the angles between fracture strikes and present-day stress-field orientation (θ). The model's output includes the so-called intrinsic densities, a parameter indexing spring occurrence to factors such as fracture type and associated deformational regime and age. The highest densities (12.2 springs/km of lineament) were associated with young shear fractures produced by brittle deformation, and the lowest (0.1) with old tensional and ductile fractures. Spectral determination also relates each orientation class to a dominant structural parameter: where spring occurrence is controlled by θ, the class is parallel to the present-day stress-field orientation; where the control is attributed to the length of fractures, the spring occurrence follows the strike of large-scale normal faults crossing the region.

    In the study of gas reservoir development, the first year topics are restricted on reservoir characterization. There are two types of reservoir characterization. One is the reservoir formation characterization and the other is the reservoir fluid characterization. For the reservoir formation characterization, calculation of conditional simulation was compared with that of unconditional simulation. The results of conditional simulation has higher confidence level than the unconditional simulation because conditional simulation considers the sample location as well as distance correlation. In the reservoir fluid characterization, phase behavior calculations revealed that the component grouping is more important than the increase of number of components. From the liquid volume fraction with pressure drop, the phase behavior of reservoir fluid can be estimated. The calculation results of fluid recombination, constant composition expansion, and constant volume depletion are matched very well with the experimental data. In swelling test of the reservoir fluid with lean gas, the accuracy of dew point pressure forecast depends on the component characterization. (author). 28 figs., 10 tabs.

  3. Advance reservoir evaluation by using NMR logging

    International Nuclear Information System (INIS)

    Based on brief explanation of the measurement principle for nuclear magnetic resonance (NMR) logging, this paper illustrates the importance of NMR logging in reservoir evaluation through typical case examples. These case examples include: Reservoir characterization and productivity evaluation by using NMR logging, determination of reservoir porosity in complex lithology, identification of oil, water and gas zones under complex reservoir conditions where resistivity log data give poor indication, guiding the implementation of completion and drilling programs, etc. Excellent application results indicate that NMR logging has its special features and advantages in comparison with conventional logging techniques. It is a very practical and very promising logging technology

    A better understanding of the subsurface geometry of the granitic bodies in Central Portugal is the main goal of this work. The results are also relevant for the assessment of the geothermal potential of the same region. The study area is located in the Central Iberian Zone where the Beiras granite batholith outcrops. These variscan granitoids were emplaced into the "Complexo Xisto-Grauváquico" (CXG), a thick and monotonous megasequences of metapelites and metagreywackes. This metasedimentary sequence is affected by the Variscan deformation phases and a late Proterozoic to Cambrian age has been generally assumed for this rocks. The granitoids in the region are attributed to the magmatic activity associated to the post-collisional stages of the Variscan orogeny during the D3 stage. The granitic bodies in the study area are considered syn-D3 and late to post-D3. To achieve the goal of the research, magnetic and gravimetric surveys where performed in order to obtain the Bouguer and magnetic anomalies. All the standard corrections were applied to the gravimetric and magnetic data. Considering and integrating all the available geological data and physical proprieties (density and magnetic susceptibility) the mentioned potential fields were simultaneously modeled. In this way it was possible to characterize the subsurface geometry of the granitic bodies in the studied region. The modeling results show that the regional tectonic setting controls the geometry of the granitic bodies as well as the structure of the host CXG metasedimentary sequence. Through the modeling of the potential field the overall geometry, average and maximum depths of the granitic bodies in the study area was obtained. Some late to post-D3 plutons outcrop in spatial continuity and as they have similar ages, a common feeding zone is assumed as the most likely scenario. The sin-D3 pluton is more abrupt and vertical, suggesting the presence of a fault contact with the late-D3 pluton. According to the

    Maintenance actions are significant for transport infrastructures but, today, costs have to be necessary limited. A proper quality control since the construction phase is a key factor for a long life cycle and for a good economy policy. For this reason, suitable techniques have to be chosen and non-destructive tests represent an efficient solution, as they allow to evaluate infrastructure characteristics in a continuous or quasi-continuous way, saving time and costs, enabling to make changes if tests results do not comply with the project requirements. Ground Penetrating Radar (GPR) is a quick and effective technique to evaluate infrastructure condition in a continuous manner, replacing or reducing the use of traditional drilling method. GPR application to railways infrastructures, during construction and monitoring phase, is relatively recent. It is based on the measuring of layers thicknesses and detection of structural changes. It also enables the assessment of materials properties that constitute the infrastructure and the evaluation of the different types of defects such as ballast pockets, fouled ballast, poor drainage, subgrade settlement and transitions problems. These deteriorations are generally the causes of vertical deviations in track geometry and they cannot be detected by the common monitoring procedures, namely the measurements of track geometry. Moreover, the development of new GPR systems with higher antenna frequencies, better data acquisition systems, more user friendly software and new algorithms for calculation of materials properties can lead to a regular use of GPR. Therefore, it represents a reliable technique to assess track geometry problems and consequently to improve maintenance planning. In Portugal, rail inspection is performed with Plasser & Theurer EM120 equipment and recently 400 MHz IDS antennas were installed on it. GPR tests were performed on the Portuguese rail network and, as case study in this paper, a renewed track was

  6. Physically-Based Shallow Landslide Susceptibility Mapping, NW of Portugal

    Science.gov (United States)

    Teixeira, Manuel; Bateira, Carlos; Soares, Laura

    2013-04-01

    Two physically-based models - Shallow Landslide Stability Analysis (SHALSTAB) and Safety Factor (SF) - are applied in Serra da Peneda (northwest of Portugal) to evaluate shallow landslide susceptibility in Tibo drainage basin. This small basin is located in an area of granitic and metasedimentary substrate, covered by different types of surficial formations (weathering mantles and slope deposits). The application of the selected models requires the determination of a set of mechanical and hydrological parameters, and the use of high resolution topographic information to create an accurate DTM. To fulfill this goal we have applied the Shallow Landslide Stability Analysis (SHALSTAB) and the SF (Safety Factor) models. The shallow landslide area was inventoried on the field. The cohesion was assessed by back analysis and the other mechanical and hydrological soil parameters were assessed on the field survey. Several susceptibility scenarios were tested with SHALSTAB model. The best SHALSTAB scenario used to assess the susceptibility is achieved using the following parameters: cohesion (c) = 2000 N/m2, soil thickness (z) = 1,2 m, internal friction (?)=32o and soil weight (?s)=14,7 KN/m3. Shallow landslide susceptibility mapping using the SF model, was based on the cartography of the factors registered on the field survey and used the following parameters: cohesion (c) = 2000 - 6000 N/m2, soil thickness (z) =1,2 m, internal friction (?)=30 - 40o; soil volumic weight (?m) = 13,7 - 15,7 KN/m3 and Hydraulic conductivity = 0 - 3,9-03 kfs. SHALSTAB scenarios were validated by overlaying the shallow landslide area (scar concentration) and selected the better susceptibility modeling. The parameters used on the SF model applied spatially variable values registered in the field survey (using the superficial formation cartography). To validate the SF model we used the AUC (Area Under the Curve) method. The two models were compared by the scar concentration and landslide potential

  8. Re-investigating the electricity consumption and economic growth nexus in Portugal

    International Nuclear Information System (INIS)

    In the previous decades, a number of studies have been conducted to analyse the causal relationship between electricity consumption and economic growth in the Portuguese economy. However, the evidence remains controversial because the previous studies do not provide clear causality evidence. This might be attributed to the omitted variables bias because most previous studies only focus on the relationship between electricity consumption and economic growth in a bi-variate model. This paper attempts to re-investigate the relationship between electricity consumption and economic growth in Portugal using a multivariate model. Based on the bounds testing approach to cointegration and the Granger causality test within the vector error-correction model (VECM), our empirical results confirm the presence of cointegration among the variables. Moreover, there is evidence of bi-directional causality between electricity consumption and economic growth in the short- and long-run. This suggests that energy is an important source of economic growth in Portugal. Therefore, energy conservation policies should not be implemented because it would deteriorate the process of economic growth and development of the Portuguese economy. - Highlights: • Electricity consumption and economic growth series in Portugal are cointegrated. • There is evidence of feedback effects between the two variables. • Energy is an important source of economic growth in Portugal

    2014-05-01

    Stomach cancer belongs to the most common malignant tumors in Portugal. Main causal factors are age, dietary habits, smoking, and Helicobacter pylori infections. As these factors do not only operate on different time dimensions, such as age, period, or birth cohort, but may also vary along space, it is of utmost interest to model temporal and spatial trends jointly. In this paper, we analyze incidence of stomach cancer in Southern Portugal between 1998 and 2006 for females and males jointly using a spatial multivariate age-period-cohort model. Thus, we avoid age aggregation and allow the exploration of heterogeneous time trends between males and females across age, period, birth cohort, and space. Model estimation is performed within a Bayesian setting assuming (gender specific) smoothing priors. Our results show that the posterior expected rate of stomach cancer is decreasing for all counties in Southern Portugal and that males around 70 have a two times higher risk of getting stomach cancer compared with their female counterparts. We further found that, except for some few counties, the spatial influence is almost constant over time and negligible in the southern counties of Southern Portugal.

    Full Text Available Sedimentation is such a crucial issue to be noted once the accumulated sediment begins to fill the reservoir dead storage, this will then influence the long-term reservoir operation. The sediment accumulated requires a serious attention for it may influence the storage capacity and other reservoir management of activities. The continuous inflow of sediment to the reservoir will decrease the capacity of reservoir storage, the reservoir value in use, and the useful age of reservoir. Because of that, the rate of the sediment needs to be delayed as possible. In this research, the delay of the sediment rate is considered based on the rate of flow of landslide of the reservoir slope. The rate of flow of the sliding slope can be minimized by way of each reservoir autonomous efforts. This effort can be performed through; the regulation of fluctuating rate of reservoir surface current that does not cause suddenly drawdown and upraising as well. The research model is compiled using the searching technique of Non Linear Programming (NLP.The rate of bank erosion for the reservoir variates from 0.0009 to 0.0048 MCM/year, which is no sigrificant value to threaten the life time of reservoir.Mean while the rate of watershed sediment has a significant value, i.e: 3,02 MCM/year for Saguling that causes to fullfill the storage capacity in 40 next years (from years 2008.

    Full Text Available Abstract Background Canine vector-borne diseases (CVBDs are caused by a wide range of pathogens transmitted to dogs by arthropods including ticks and insects. Many CVBD-agents are of zoonotic concern, with dogs potentially serving as reservoirs and sentinels for human infections. The present study aimed at assessing the seroprevalence of infection with or exposure to Dirofilaria immitis, Ehrlichia canis, Borrelia burgdorferi sensu lato, Anaplasma spp. and Leishmania infantum in dogs in Portugal. Methods Based on 120 veterinary medical centres from all the regions of mainland and insular Portugal, 557 apparently healthy and 628 CVBD-suspect dogs were sampled. Serum, plasma or whole blood was tested for qualitative detection of D. immitis antigen and antibodies to E. canis, B. burgdorferi s. l., Anaplasma spp. and L. infantum with two commercial in-clinic enzyme-linked immunosorbent assay kits. Odds ratios (OR were calculated by logistic regression analysis to identify independent risk factors of exposure to the vector-borne agents. Results Total positivity levels to D. immitis, E. canis, B. burgdorferi, Anaplasma spp., L. infantum, one or more agents and mixed agents were 3.6%, 4.1%, 0.2%, 4.5%, 4.3%, 14.0% and 2.0% in the healthy group, and 8.9%, 16.4%, 0.5%, 9.2%, 25.2%, 46.3% and 11.6% in the clinically suspect group, respectively. Non-use of ectoparasiticides was a risk factor for positivity to one or more agents both in the apparently healthy (OR = 2.1 and CVBD-suspect (OR = 1.5 dogs. Seropositivity to L. infantum (OR = 7.6, E. canis (OR = 4.1 and D. immitis (OR = 2.4 were identified as risk factors for the presence of clinical signs compatible with CVBDs. Positivity to mixed agents was not found to be a risk factor for disease. Conclusions Dogs in Portugal are at risk of becoming infected with vector-borne pathogens, some of which are of zoonotic concern. CVBDs should be considered by practitioners and prophylactic measures must be put in

    Reservoir regulation process in the Yangtze River basin is mainly divided into two types of flood regulation and initiating benefit regulation. The present reservoir management system and operation mode are mainly for dealing with or coordinating of flood control and benefit initiation as well as benefit distribution among various beneficial functions. From the view point of river ecosystem protection, the current regulation mode has two kinds of problems: firstly, most of the reservoir regulation plans do not consider ecosystem protection at downstream of dams and needs of environment protection in reservoir areas; secondly, integrated regulation or management of water resources is ignored. It is very necessary to improve reservoir regulation mode, bearing problems faced by regulation of the Three Gorges reservoir and issues related to cascade development and regulation in Tuojiang and Minjiang River basins in mind. In accordance with the concept of scientific development, and the philosophy of "ensuring a healthy Yangtze River and promoting the har-mony between human and water", taking flood control, benefit initiation and eco-system as a whole, this paper put for-ward the basic consideration to improve reservoir regulation as follows : on the basis of requirements of ecosystem protec-tion at downstream of dams and needs of environment protection in reservoir areas, we should bring the functions of res-ervoir such as flood control and benefit initiation into full play, control the negative influence to the ecosystem at down-stream of dams and the environment in reservoir areas in an endurable scope, and restore the ecosystem and the environ-ment step by step. This paper put forward the relevant regulation process aiming at the idiographic problems such as pro-tection of ecosystem at downstream of dams and environment in reservoir areas, protection of aquatic wildlife species and fish species, regulation of sediment and protection of wetland.

    Portugal has the highest gastric cancer mortality rates in Western Europe, along with high prevalences of Helicobacter pylori infection. Monitoring their trends is essential to predict the burden of this cancer. We aimed to quantify time trends in gastric cancer mortality in Portugal and in each administrative region, and to compute short-term predictions, as well as to describe the prevalence of H. pylori infection, through a systematic review. Joinpoint analyses were used to identify significant changes in sex-specific trends in gastric cancer age-standardized mortality rates (ASMR) and to estimate annual percent changes (APC). The most recent trends were considered to compute estimates up to 2020 by adjusting Poisson regression models. We searched PubMed and IndexRMP to identify studies carried out in Portugal reporting the prevalence of H. pylori. Gastric cancer mortality has been decreasing in Portugal since 1971 in men (from ASMR=55.3/100 000; APC=-2.4, 95% confidence interval: -2.5 to -2.3) and since 1970 in women (from ASMR=28.0/100 000; APC=-2.8, 95% confidence interval: -2.9 to -2.7), although large regional differences were observed. Predicted ASMR for 2015 and 2020 were 18.8/100 000 and 16.7/100 000 for men and 8.5/100 000 and 7.4/100 000 for women, respectively. The prevalence of H. pylori varied from almost 5% at 0.5-2 years to just over 90% at 70 years or more. No consistent variation was observed since the 1990s. The downward trends in mortality rates are expected to remain in the next decades. The high prevalence of H. pylori infection across age groups and studies from different periods shows a large potential for decrease in the burden of gastric cancer in Portugal.

    Detecting the saturation of a fractured reservoir using shear waves is possible when the fractures have a geometry that induces a component of movement perpendicular to the fractures. When such geometry is present, vertically traveling shear waves can be used to examine the saturation of the fractured reservoir. Tilted, corrugated, and saw-tooth fracture models are potential examples.

  15. Economics of Developing Hot Stratigraphic Reservoirs

    2014-09-01

    Stratigraphic geothermal reservoirs at 3 – 4 km depth in high heat-flow basins are capable of sustaining 100 MW-scale power plants at about 10 c/kWh. This paper examines the impacts on the levelized cost of electricity (LCOE) of reservoir depth and temperature, reservoir productivity, and drillhole/casing options. For a reservoir at 3 km depth with a moderate productivity index by hydrothermal reservoir standards (about 50 L/s/MPa, 5.6 gpm/psi), an LCOE of 10c/kWh requires the reservoir to be at about 200°C. This is the upper temperature limit for pumps. The calculations assume standard hydrothermal drilling costs, with the production interval completed with a 7 inch liner in an 8.5 inch hole. If a reservoir at 4 km depth has excellent permeability characteristics with a productivity index of 100 L/s/MPa (11.3 gpm/psi), then the LCOE is about 11 c/kWh assuming the temperature decline rate with development is not excessive (< 1%/y, with first thermal breakthrough delayed by about 10 years). Completing wells with modest horizontal legs (e.g. several hundred meters) may be important for improving well productivity because of the naturally high, sub-horizontal permeability in this type of reservoir. Reducing the injector/producer well ratio may also be cost-effective if the injectors are drilled as larger holes.

    Water levels in reservoirs are generally not allowed to exceed the flood-limited water level during the flood season, which means that huge amounts of water spill in order to provide adequate storage for flood prevention and that it is difficult to fill the reservoir fully at the end of year. Early reservoir refill is an effective method for addressing the contradiction between the needs of flood control and of comprehensive utilization. This study selected the Danjiangkou Reservoir, which is the water source for the middle route of the South-North Water Diversion Project (SNWDP) in China, as a case study, and analyzed the necessity and operational feasibility of early reservoir refill. An early reservoir refill model is proposed based on the maximum average storage ratio, optimized by the progressive optimality algorithm, and the optimal scheduling schemes were obtained. Results show that the best time of refill operation for the Danjiangkou Reservoir is September 15, and the upper limit water level during September is 166 m. The proposed early refill scheme, in stages, can increase the annual average storage ratio from 77.51% to 81.99%, and decrease spilled water from 2.439×109 m3 to 1.692×109 m3, in comparison to the original design scheme. The suggested early reservoir refill scheme can be easily operated with significant comprehensive benefits, which may provide a good reference for scheduling decision-making.

    Full Text Available Water levels in reservoirs are generally not allowed to exceed the flood-limited water level during the flood season, which means that huge amounts of water spill in order to provide adequate storage for flood prevention and that it is difficult to fill the reservoir fully at the end of year. Early reservoir refill is an effective method for addressing the contradiction between the needs of flood control and of comprehensive utilization. This study selected the Danjiangkou Reservoir, which is the water source for the middle route of the South-North Water Diversion Project (SNWDP in China, as a case study, and analyzed the necessity and operational feasibility of early reservoir refill. An early reservoir refill model is proposed based on the maximum average storage ratio, optimized by the progressive optimality algorithm, and the optimal scheduling schemes were obtained. Results show that the best time of refill operation for the Danjiangkou Reservoir is September 15, and the upper limit water level during September is 166 m. The proposed early refill scheme, in stages, can increase the annual average storage ratio from 77.51% to 81.99%, and decrease spilled water from 2.439 × 109 m3 to 1.692 × 109 m3, in comparison to the original design scheme.

    Protection and enhancement of water quality is essential for attaining the full complement of beneficial uses of TVA reservoirs. The responsibility for improving and protecting TVA reservoir water quality is shared by various federal, state, and local agencies, as well as the thousands of corporations and property owners whose individual decisions affect water quality. TVA's role in this shared responsibility includes collecting and evaluating water resources data, disseminating water resources information, and acting as a catalyst to bring together agencies and individuals that have a responsibility or vested interest in correcting problems that have been identified. This report is one in a series of status reports that will be prepared for each of TVA's reservoirs. The purpose of this status report is to provide an up-to-date overview of the characteristics and conditions of Wheeler Reservoir, including: reservoir purposes and operation; physical characteristics of the reservoir and the watershed; water quality conditions: aquatic biological conditions: designated, actual, and potential uses of the reservoir and impairments of those uses; ongoing or planned reservoir management activities. Information and data presented here are form the most recent reports, publications, and original data available. 21 refs., 8 figs., 29 tabs.

    The identification and evaluation of oil reservoir with logging data are one of most important ways in geologic logging services. For the last decades, with the further development of the oil & gas exploration, great advances have been achieved in techniques on the acquisition, processing and interpretative evaluation of logging data. How to identify fluid characteristics and evaluate the productivity in light oil reservoir (the crude density being between 0.74g/cm3 and 0.82g/cm3)has become one of the difficulties.With the establishment of the regional interpretation criterion of the study blocks, the optimized logging parameters that reflect the reservoir characteristics have been used to establish the chart for the interpretation of oil-water reservoir combining with well logging parameters. Then, to begin with geologic reserves of crude in single well, we establish evaluation criterion for productivity in oil reservoir with determining lower limit value of the reservoir and applying the relationship between chart parameters. The techniques are verified in production and get better effect.On the basis of the reservoir characteristics analysis of both basin A and B, We established the evaluation method of static productivity on light oil reservoir with getting quantitative evaluation parameters after quantitatively evaluating the date of core, pyrolysis chromatogram and gas chromatogram. It provides new technique 7 for new well interpretation and old well review, as well as evidence for project.design of well testing.

    As a part of a larger project co-funded by the United States Department of Energy (US DOE) to evaluate the potential of formations within the Cambro-Ordovician strata above the Mt. Simon as potential targets for carbon sequestration in the Illinois and Michigan Basins, the Illinois Clean Coal Institute (ICCI) requested Schlumberger to evaluate the potential injectivity and carbon dioxide (CO2) plume size of the Cambrian Potosi Formation. The evaluation of this formation was accomplished using wireline data, core data, pressure data, and seismic data from the US DOE-funded Illinois Basin–Decatur Project (IBDP) being conducted by the Midwest Geological Sequestration Consortium in Macon County, Illinois. In 2010, technical performance evaluations on the Cambrian Potosi Formation were performed through reservoir modeling. The data included formation tops from mud logs, well logs from the VW1 and the CCS1 wells, structural and stratigraphic formation from three dimensional (3D) seismic data, and field data from several waste water injection wells for Potosi Formation. Intention was for two million tons per annum (MTPA) of CO2 to be injected for 20 years. In the preceding, the 2010 Potosi heterogeneous model (referred to as the "Potosi Dynamic Model 2010" in this topical report) was re-run using a new injection scenario; 3.2 MTPA for 30 years. The extent of the Potosi Dynamic Model 2010, however, appeared too small for the new injection target. It was not sufficiently large enough to accommodate the evolution of the plume. The new model, Potosi Dynamic Model 2013a, was built by extending the Potosi Dynamic Model 2010 grid to 30 miles x 30 miles (48.3km x48.3km), while preserving all property modeling workflows and layering. This model was retained as the base case of Potosi Dynamic Model 2013a. The Potosi reservoir model was updated to take into account the new data from the verification well VW2 which was drilled in 2012. The new porosity and permeability modeling was

    Full Text Available Abstract Many European protected areas were legally created to preserve and maintain biological diversity, unique natural features and associated cultural heritage. Built over centuries as a result of geographical and historical factors interacting with human activity, these territories are reservoirs of resources, practices and knowledge that have been the essential basis of their creation. Under social and economical transformations several components of such areas tend to be affected and their protection status endangered. Carrying out ethnobotanical surveys and extensive field work using anthropological methodologies, particularly with key-informants, we report changes observed and perceived in two natural parks in Trás-os-Montes, Portugal, that affect local plant-use systems and consequently local knowledge. By means of informants' testimonies and of our own observation and experience we discuss the importance of local knowledge and of local communities' participation to protected areas design, management and maintenance. We confirm that local knowledge provides new insights and opportunities for sustainable and multipurpose use of resources and offers contemporary strategies for preserving cultural and ecological diversity, which are the main purposes and challenges of protected areas. To be successful it is absolutely necessary to make people active participants, not simply integrate and validate their knowledge and expertise. Local knowledge is also an interesting tool for educational and promotional programs.

  11. Morphological and molecular diversity of Unionidae (Mollusca, Bivalvia from Portugal

    Reis, J.

    2013-06-01

    Full Text Available Freshwater mussels from the family Unionidae are known to exhibit a high level of ecological phenotypic plasticity that is reflected in their shell shape. This variation has caused uncertainty on systematics and taxonomy of the group. Several naiad populations from nine river basins from Portugal were analyzed genetically, using two mitochondrial gene fragments (16SrRNA and Cytochrome Oxidase I and morphologically, using ANOVA analyses of shell dimmensions. Molecular phylogenetic analyses were used to revise the systematics and to infer an evolutionary hypothesis for the family at the western-most Atlantic Iberian Peninsula. Genetic and morphological data were in agreement and supported the occurrence of 5 species in the region: Anodonta anatina, Anodonta cygnea, Potomida littoralis, Unio tumidiformis and Unio delphinus. The differentiation of all these species, except A. cygnea, is thought to have taken place during the isolation of the Iberian Peninsula and formation of the current river basins in the Tertiary. The possibility of A. cygnea being a relatively recent introduction is discussed. Basic morphometric measures of the shell proved to be useful to separate Unio species, but also seem to be strongly affected by environmental conditions. The high intra-specific morphologic variation was partially related to the species’ high level of phenotypic plasticity, but seems to have an important role in evolutionary processes.Las náyades de la familia Unionidae tienen gran plasticidad fenotípica, lo que se refleja en la forma de su concha. Esta variabilidad morfológica ha sido causa de gran confusión en la taxonomía y sistemática del grupo.

    After the first report of Undaria pinnatifida in north Portugal (between 1999 and 2007), a rapid spread of this species could be expected due to the presence of a stable population and the favourable environmental conditions proposed by distribution models. However, field surveys showed that U. pinnatifida was not present in most of the rocky shores in north Portugal. It seems that U. pinnatifida cannot outcompete native species outside of marinas in north Portugal. The only population in natural rocky shores was found in Buarcos, where this species was frequent. This study provides density data of U. pinnatifida that will be useful in the future to monitor changes on its abundance and distribution in the centre and south of Portugal.

    Full Text Available This paper presents the first evidence for Palaeolithic portable art in Southern Portugal. This include two plaques, dated between 20,500 and 19,500 BP from Solutrean levels from the site of Vale Boi, Western Algarve (Portugal. One of the pieces is a small engraved schist plaque (14,6 × 8,1 mm with abstract lines on one side. The other artefact is an 8 × 5 cm schist plaque. One side is an oxide natural deposit, used to produce dye; the other side has three aurochs and a probable cervid. Stilistic information and the engraving sequence indicate probably production by a single artist. The stylistic characteristics are in full agreement withi those from late Gravettian and early Solutrean art known from Valencia, Andalucia (Spain and the Côa valley (Portugal, thus confirming the absolute AMS dates from the Vale Boi Levels.

Un espacio económico en desarrollo, el del Atlántico septentrional, comprendía ambos territorios y se organizaba a partir de los grandes centros feriales de Amberes, Lyon y Medina. El gran tráfico mercantil transoceánico se hacía presente en este escenario europeo gracias a la intervención de España y Portugal, pero con papeles bien distintos: España, incontinente, drenando el oro y la plata americanos hacia Europa, Portugal suministrando las apreciadas mercancías orientales. Las ferias de Medina del Campo y los mercaderes castellanos como Simón Ruiz se convierten en colaboradores necesarios de los mercaderes portugueses, pues a través de éstos negociaban los reembolsos o inversiones financieras en las plazas europeas; sin embargo, para ello era preciso un buen conocimiento de los negocios cambiarlos y su oportunidad, atendiendo a la cotización de las distintas monedas y a demanda de dinero en las ferias europeas. De la mano del mercader medinense entran los lisboetas en las grandes finanzas y la concertación de asientos con la Corona, aunque tal vez sin la pujanza que Felipe II hubiese deseado.ABSTRACT: The correspondence studied shows the importance that had, for this period of time (1563-1580, the relationship between Castille and Portugal.

    Atmospheric lightning is an important atmospheric hazard, as cloud-to-ground discharges (CGD) can affect people, can lead to severe damages in buildings, equipment, and can trigger forest fires. The potential damages directly linked to CGD have been increasing as society develops (e.g. due to greater use of electronic equipment). However, an adequate risk assessment requires an analysis in depth of the CGD spatial-temporal distributions. Further, the climate change impacts on the lightning activity still present many uncertainties. Nevertheless, there is a wide agreement in the scientific community that climate change in Europe is likely to impact on frequency, severity and location of extreme events. The Portuguese meteorological office (IPMA) maintains a lightning detection network (LDN) over mainland Portugal since June 2002. Due to the recent and short time period of available data, there are only few studies using this dataset. The RAIDEN project (contract number PTDC/CTE-ATM/101931/2008) - Lightning activity in Portugal: variability patterns and socioeconomic impacts - aims (1) to characterize the spatial-temporal variability of the lightning activity over mainland Portugal and (2) to assess its corresponding risks and socioeconomic impacts. This study is based on data provided by the Portuguese LDN and follows a multidisciplinary approach. As such, the project is focused on a 7-year period (2003-2009) of CGD data and the research program started studying the main climatological aspects of lightning activity, regarding the spatial patterns of the CGD occurrences, as well as their temporal variability at different time scales (inter-annual, seasonal and daily variability). The spatial patterns of the CGD occurrences over Portugal have also been categorized taking into account their spatial spread and strength using a clustering methodology. Furthermore, the dynamical mechanisms underlying the CGD occurrences, including the identification of the main lightning

    In the last decade a permanent seismic network of 30 broadband stations, complemented by dense temporary deployments, covered Portugal. This extraordinary network coverage enables now the computation of a high-resolution image of the seismicity of Portugal, which in turn will shed light on the seismotectonics of Portugal. The large data volumes available cannot be analyzed by traditional time-consuming manual location procedures. In this presentation we show first results on the automatic detection and location of earthquakes occurred in a selected region in the south of Portugal Our main goal is to implement an automatic earthquake detection and location routine in order to have a tool to quickly process large data sets, while at the same time detecting low magnitude earthquakes (i.e., lowering the detection threshold). We present a modified version of the automatic seismic event location by waveform coherency analysis developed by Grigoli et al. (2013, 2014), designed to perform earthquake detections and locations in continuous data. The event detection is performed by continuously computing the short-term-average/long-term-average of two different characteristic functions (CFs). For the P phases we used a CF based on the vertical energy trace, while for S phases we used a CF based on the maximum eigenvalue of the instantaneous covariance matrix (Vidale 1991). Seismic event detection and location is obtained by performing waveform coherence analysis scanning different hypocentral coordinates. We apply this technique to earthquakes in the Alentejo region (South Portugal), taking advantage from a small aperture seismic network installed in the south of Portugal for two years (2010 - 2011) during the DOCTAR experiment. In addition to the good network coverage, the Alentejo region was chosen for its simple tectonic setting and also because the relationship between seismicity, tectonics and local lithospheric structure is intriguing and still poorly understood.

    The record and analysis of statistical information on disaster occurrence, impacts and losses have been made worldwide in recent years. The development of natural disasters databases is crucial for risk management purposes, because it allows improving systems of indicators on disaster risk and vulnerability at national and sub-national scales. During the last century, Portugal was affected by several destructive natural disasters, namely of hydrologic (floods) and geomorphologic (landslides) origin. However, only recently risk prevention and management was assumed to be a national priority by the Portuguese Government. The basic information on past floods and landslides that occurred in Portugal is disperse and incomplete, and this is a shortcoming for the implementation of effective disaster mitigation measures, particularly when it is expectable an increase of frequency, magnitude, dimension and complexity of the hydro-geomorphologic phenomena resulting from climate change. In this work we present a preliminary assessment of hydro-geomorphologic disasters occurred in Portugal during the 20th century, based on the systematic survey of daily national newspapers. We included into a database those floods and landslides that produced, alternatively, dead people, injured people, missing people, evacuated and homeless. A total of 937 hydro-geomorphologic events were registered. In addition to physical and material damages, these events produced economic losses amounting to millions Euros. Our attention will focus on the geographic distribution and the temporal dimension of disastrous floods and landslides occurred in Portugal, and the temporal trends of hydro-geomorphologic disasters will be presented. The preliminary results shown that disastrous floods and landslides have been more frequent on the most populated regions of Portugal: the metropolitan areas of Lisbon and Oporto. In addition, data shows that disastrous hydrologic and geomorphologic phenomena were more

    Three different uses of a recurrent neural network (RNN) as a reservoir that is not trained but instead read out by a simple external classification layer have been described in the literature: Liquid State Machines (LSMs), Echo State Networks (ESNs) and the Backpropagation Decorrelation (BPDC) learning rule. Individual descriptions of these techniques exist, but a overview is still lacking. Here, we present a series of experimental results that compares all three implementations, and draw conclusions about the relation between a broad range of reservoir parameters and network dynamics, memory, node complexity and performance on a variety of benchmark tests with different characteristics. Next, we introduce a new measure for the reservoir dynamics based on Lyapunov exponents. Unlike previous measures in the literature, this measure is dependent on the dynamics of the reservoir in response to the inputs, and in the cases we tried, it indicates an optimal value for the global scaling of the weight matrix, irrespective of the standard measures. We also describe the Reservoir Computing Toolbox that was used for these experiments, which implements all the types of Reservoir Computing and allows the easy simulation of a wide range of reservoir topologies for a number of benchmarks.

    In order to predict future production of oil and gas from a petroleum reservoir, it is important to have a good description of the reservoir in terms of geometry and physical parameters. This description is used as input to large numerical models for the fluid flow in the reservoir. With increased quality of seismic data, it is becoming possible to extend their use from the study of large geologic structures such as seismic horizons to characterization of the properties of the reservoir between the horizons. Uncertainties because of the low resolution of seismic data can be successfully handled by means of stochastic modeling, and spatial statistics can provide tools for interpolation and simulation of reservoir properties not completely resolved by seismic data. This thesis deals with stochastic reservoir modeling conditioned to seismic data and well data. Part I presents a new model for stochastic reservoir characterization conditioned to seismic traces. Part II deals with stochastic simulation of high resolution impedance conditioned to measured impedance. Part III develops a new stochastic model for calcite cemented objects in a sandstone background; it is a superposition of a marked point model for the calcites and a continuous model for the background.

    2014-10-01

    Full Text Available The Lower Cambrian Longwangmiao Fm carbonatite gas reservoirs in the Leshan-Longnüsi Paleouplift in the Sichuan Basin feature strong heterogeneity, well-developed fractures and caverns, and a high content of H2S, so these reservoirs are prone to reservoir damages caused by the invasion of drilling fluid or the improper well completion, so to minimize the reservoir skin factor is key to achieving high yield of oil and gas in this study area. Therefore, based on the geological characteristics of the Longwangmiao reservoirs, the binomial productivity equation was applied to demonstrate the possibility and scientificity of minimizing the skin factor. According to the current status of reservoir stimulation, the overall skin factors of reservoir damage caused by drilling fluid invasion, improper drilling and completion modes etc were analyzed, which shows there is still potential for skin factor reduction. Analysis of reservoir damage factors indicates that the main skin factor of Longwangmiao Fm reservoirs consists of that caused by drilling fluid and by improper completion modes. Along with the minimization of skin factor caused by drilling and improper completion, a fracture-network acidizing process to achieve “non-radial & network-fracture” plug-removal by making good use of natural fractures was proposed according to the characteristics of Longwangmiao Fm carbonatite reservoirs.

    Full Text Available The traditional operation rule of Three Gorges reservoir has mainly focused on water for flood control, power generation, navigation, water supply and recreation and given less attention to the negative impacts of reservoir operation on river ecosystem. In order to reduce the negative influence of reservoir operation, ecological operation of the reservoir should be studied to maintain healthy river ecosystem. The study considered the ecological operation targets, including maintaining river environmental flow and protecting the spawning and reproduction of Chinese sturgeon and four major Chinese carps. Based on the flow data from 1900 to 2006 of Yichang gauge as the control station of the Yangtze River, the minimal and optimal river environmental flows were analyzed, and eco-hydrological targets of Chinese sturgeon and four major Chinese carps in the Yangtze River were calculated. The paper proposed a reservoir ecological operation model of comprehensively considering flood control, power generation, navigation and ecological environment. Three typical periods including wet, normal and dry year were selected and particle swarm optimization was applied to analyze the model. The results show that there are different influences of ecological operation rules on economic benefit of hydropower station and reservoir ecological operation model can simulate the flood pulse for requirement of spawning of Chinese sturgeon and four major Chinese carps. Finally, ecological operation measures of Three Gorges reservoir were proposed. According to the results, by adopting a suitable re-operation scheme, the hydropower benefit of the reservoir will not decrease dramatically while the ecological demand can be met. The results provide the reference for making the reasonable operation schemes for Three Gorges reservoir.

  6. Improving reservoir history matching of EM heated heavy oil reservoirs via cross-well seismic tomography

    Enhanced recovery methods have become significant in the industry\\'s drive to increase recovery rates from oil and gas reservoirs. For heavy oil reservoirs, the immobility of the oil at reservoir temperatures, caused by its high viscosity, limits the recovery rates and strains the economic viability of these fields. While thermal recovery methods, such as steam injection or THAI, have extensively been applied in the field, their success has so far been limited due to prohibitive heat losses and the difficulty in controlling the combustion process. Electromagnetic (EM) heating via high-frequency EM radiation has attracted attention due to its wide applicability in different environments, its efficiency, and the improved controllability of the heating process. While becoming a promising technology for heavy oil recovery, its effect on overall reservoir production and fluid displacements are poorly understood. Reservoir history matching has become a vital tool for the oil & gas industry to increase recovery rates. Limited research has been undertaken so far to capture the nonlinear reservoir dynamics and significantly varying flow rates for thermally heated heavy oil reservoir that may notably change production rates and render conventional history matching frameworks more challenging. We present a new history matching framework for EM heated heavy oil reservoirs incorporating cross-well seismic imaging. Interfacing an EM heating solver to a reservoir simulator via Andrade’s equation, we couple the system to an ensemble Kalman filter based history matching framework incorporating a cross-well seismic survey module. With increasing power levels and heating applied to the heavy oil reservoirs, reservoir dynamics change considerably and may lead to widely differing production forecasts and increased uncertainty. We have shown that the incorporation of seismic observations into the EnKF framework can significantly enhance reservoir simulations, decrease forecasting

  7. The freshwater reservoir effect in radiocarbon dating

    Philippsen, Bente

    case studies will show the degree of variability of the freshwater reservoir effect over short and long timescales. Radiocarbon dating of recent water samples, aquatic plants and animals, shows that age differences of up to 2000 years can occur within one river. In the Limfjord, freshwater influence...... caused reservoir ages to vary between 250 and 700 years during the period 5400 BC - AD 700. Finally, I will discuss the implications of the freshwater reservoir effect for radiocarbon dating of Mesolithic pottery from inland sites of the Ertebølle culture in Northern Germany....

  8. Safety drain system for fluid reservoir

    England, John Dwight (Inventor); Kelley, Anthony R. (Inventor); Cronise, Raymond J. (Inventor)

    2012-01-01

    A safety drain system includes a plurality of drain sections, each of which defines distinct fluid flow paths. At least a portion of the fluid flow paths commence at a side of the drain section that is in fluid communication with a reservoir's fluid. Each fluid flow path at the side communicating with the reservoir's fluid defines an opening having a smallest dimension not to exceed approximately one centimeter. The drain sections are distributed over at least one surface of the reservoir. A manifold is coupled to the drain sections.

  9. Simulation of Radon Transport in Geothermal Reservoirs

    Semprini, Lewis; Kruger, Paul

    1983-12-15

    Numerical simulation of radon transport is a useful adjunct in the study of radon as an in situ tracer of hydrodynamic and thermodynamic numerical model has been developed to assist in the interpretation of field experiments. The model simulates transient response of radon concentration in wellhead geofluid as a function of prevailing reservoir conditions. The radon simulation model has been used to simulate radon concentration response during production drawdown and two flowrate transient tests in vapor-dominated systems. Comparison of model simulation with experimental data from field tests provides insight in the analysis of reservoir phenomena such as propagation of boiling fronts, and estimates of reservoir properties of porosity and permeability thickness.

    1989-12-01

    The main objective of this research project is to establish dispersivity, {alpha}{sub d}, as an oil reservoir rock characteristic and to use this reservoir rock property to enhance crude oil recovery. A second objective is to compare the dispersion coefficient and the dispersivity of various reservoir rocks with other rock characteristics such as: porosity, permeability, capillary pressure, and relative permeability. The dispersivity of a rock was identified by measuring the physical mixing of two miscible fluids, one displacing the other in a porous medium. 119 refs., 27 figs., 12 tabs.

  11. Particulate Matter and Health Risk under a Changing Climate: Assessment for Portugal

    2012-01-01

    Full Text Available The potential impacts of climate-induced changes in air pollution levels and its impacts on population health were investigated. The IPCC scenario (SRES A2 was used to analyse the effects of climate on future PM10 concentrations over Portugal and their impact on short-term population exposure and mortality. The air quality modelling system has been applied with high spatial resolution looking on climate changes at regional scale. To quantify health impacts related to air pollution changes, the WHO methodology for health impact assessment was implemented. The results point to 8% increase of premature mortality attributed to future PM10 levels in Portugal. The pollution episodes with daily average PM10 concentration above the current legislated value (50 μg·m−3 would be responsible for 81% of attributable cases. The absolute number of deaths attributable to PM10 under future climate emphasizes the importance of indirect effects of climate change on human health.

  12. Exploring the Personality Traits of Portugal as a Tourist Destination: Perspective of the Czech Market

    Directory of Open Access Journals (Sweden)

    Manuela Guerreiro

    2015-06-01

    Full Text Available The personality of a destination is vital to build a coherent destination brand and strengthen the place identity. Furthermore, brand personality appears in literature as a strategic axis that can be explored by tourist destinations in order to differentiate themselves from competitors. Since a brand encompasses not only functional but also symbolic elements, its image, as perceived by consumers, can be assessed with respect to both its functional and psychological components. Hence, this exploratory study investigates the brand personality of Portugal as a tourist destination, from the perspective of the Czech market, through a destination image approach. The online survey instrument included open-ended items to depict functional and psychological destination features and additional questions to characterize the profile of a sample of Czech university students. The main findings of this research highlight positive personality traits that are related to the brand of Portugal, which suggest its potential as a vacation destination for the Czech market under study.

  13. Weak Societal Roots, Strong Individual Patrons? Patronage & Party Organization in Portugal

    2009-12-01

    Full Text Available We examine why patronage may constitute an important dimension of analysis in the study of Portuguese political parties and the evolution of its party system. In particular, we are interested in exploring two inter-related aspects: first, what is the role of patronage for party organisations in Portugal? And second, how does it impact on intra-party functioning? Overall, access to state resources appears to be crucial in the rapid building of the party organisations and in their subsequent maintenance, potentially creating also barriers to entry for new competitors. This pattern is to a large extent explained by the context in which parties emerged in Portugal, which substantially shaped their organisational structure and societal roots.

  15. Using Choice Experiments to Assess Environmental Impacts of Dams in Portugal

    Directory of Open Access Journals (Sweden)

    Anabela Botelho

    2015-08-01

    Full Text Available Despite their well-known benefits in electricity production, dams are also responsible for some adverse environmental impacts affecting particularly the wellbeing of residents of the local communities. These environmental damages have not been included in the cost-benefit analysis of hydropower developments mainly because of the difficulty to determine their value. The prime objective of this paper is to measure the economic values of several environmental impacts due to the dams' activity in Portugal, using a discrete choice experiments approach. With the results of this research paper, we expect to contribute to a more efficient and thorough cost-benefit analysis within the complex process of deciding the optimal location of future dams to be built not only in Portugal, but elsewhere. The addition of this stage to the decision-making process allows the integration of economic, social and environmental dimensions, promoting a richer and more informed decision process.

    Mota, Rui Pedro; Domingos, Tiago [Environment and Energy Section, DEM, Instituto Superior Tecnico (Portugal); Martins, Victor [Department of Economics, Instituto Superior de Economia e Gestao (Portugal)

    2010-08-15

    The context of this paper is the measurement of welfare and weak sustainability (defined as non-declining utility) in dynamic economies, i.e., comprehensive or green accounting. We estimate green net national income (GNNI) and genuine saving (GS) for Portugal, for the years 1990 to 2005, accounting for the disamenity of air pollution emissions, the depreciation of commercial forests and the value of time, discussing the implications of the assumptions underlying the inclusion of these terms in the green accounting model. The influence of short-run cycles is analyzed by estimating GNNI excluding business cycles. Our results suggest that business cycles affect the sustainability message of GNNI. We find that potential GNNI is growing and GS is positive in the analyzed period, thereby not indicating a weak sustainability problem in Portugal, although both depict a trend towards unsustainability. Excluding technological progress there is a contradiction in the sustainability message of GNNI and GS. (author)

  19. Legislation for higher education disabled students in Brazil and Portugal: some reflections

    Directory of Open Access Journals (Sweden)

    Francisco Ricardo Lins Vieira de Melo

    2016-08-01

    Full Text Available This study aims to make a critical analysis of legislation regulating the inclusion of disabled students in higher education in Brazil and Portugal. Based on a documentary study, conducted between September and November 2015, the legal standards in recent decades have been analyzed. The results point out different stages of construction of the inclusion policy in the researched countries. It is emphasized that there is a significant variety of norms in the Brazilian context to ensure that these students have equal opportunities, and a scarcity of regulations in Portugal. The legislation has been referred to as an important factor for the development of inclusive education; however it is noteworthy that the existence of legislation does not necessarily imply it is actually complied. Besides legislation, removing barriers for the full participation and learning of disabled students involves awareness, investment in resources, public policy makers and managers’ scientific knowledge to ensure a quality education throughout life for all people.
