    Full Text Available Cases of contamination by metals in the water wells of the Cavado Valley in north-west Portugal can be attributed to the heavy leaching of clay soils due to an excess of nitrogen resulting from the intensive use of fertilisers in agricultural areas. This work focuses on the natural weathering characteristics of soils, particularly the clay material, through the study of samples collected near the River Cavado. Samples taken from various sites, after physico-chemical characterisation, were subjected to clay dissolution tests, using sodium salts of different ionic forces, to detect the relationship between certain physico-chemical parameters of water, such as pH, nitrate, chloride and sulphate content, in the dissolution of clay and the subsequent extraction of such cations as Al, Fe and K. In acidic sandy clay soils, the mineralogical composition of which was characterised by a predominance of quartz, micas, kaolinite and K-feldspars, decreases of the clay material/water pH ratio increases dissolution of the micaceous and K-feldspars phases. The presence of nitrates in the aqueous solution apparently advanced the extraction of all three cations Al, Fe and K. The specific surface area of the clay material showed a significant correlation with the main kinetic parameters of cation extraction.

    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

    The present study is developed for the municipality of Santa Marta de Penaguião (70 square kilometers), located in the Douro Valley region (Northern Portugal). In the past, several destructive landslides occurred in this area, and were responsible for deaths and destruction of houses and roads. Despite these losses, mitigation and landslide zonation programs are missing, and the land use planning at the municipal level did not solve yet the problem. The study area is mainly composed by metamorphic rocks (e.g., schist and quartzite). These rocks are strongly fractured, and weathered materials are abundant in clayed schist, mainly in those areas where agricultural terraces were constructed centuries ago for the vineyard monoculture. From the geomorphologic point of view, the study area is characterized by deep incised valleys, tectonic depressions and slopes controlled by the geological structure. Elevation ranges from 49 m to 1416 m. The main landslide triggering factor is rainfall and the mean annual precipitation ranges from 700 mm (in the bottom of fluvial valleys) to 2500 mm (in the mountains top). A landslide inventory was performed in 2005-2009 using aerial photo-interpretation (1/5.000 scale) and field work. The inventory includes 848 landslides, most of shallow translational slide type (85% of total slope movements). The landslide density is 10.5 events/square kilometers, and the average landslide area is 535 square meters. The susceptibility to shallow translational slide occurrence was assessed at the 1: 10 000 scale in a GIS environment. Two different bivariate statistical methods were used to evaluate landslide susceptibility: the Information Value and the Fuzzy Logic Gamma operator. Eight conditioning factors were weighted and integrated to model susceptibility: slope angle, slope aspect, slope curvature, lithology, geomorphologic units, fault density, land use and terrace structures build in slopes. The susceptibility results were validated using a

    Full Text Available The Côa valley rock art would have been completely submerged if construction of the large Foz Côa dam, began in 1992, had been allowed to continue. The dam project was halted in 1995 and a 200 km2, archaeological park was established in this area, which is now legally protected at the highest level as a National Monument. Public access to selected sites is organized through four-wheel drive tours of groups of eight people accompanied by guides appropriately trained in archaeology and rock art studies. Visitor Centers were set-up in restored traditional houses located in the villages around the periphery of the park. A museum of art and archaeology and associated research facilities is to be established at the site of the now abandoned dam. The universal importance of the valley's cultural heritage and the landmark nature of the Portuguese government's decision to preserve it in spite of the huge financial loss involved have been widely acclaimed. As a result, the prehistoric rock art of the Côa was included in the World Heritage List in December 1998.

Das amostras analisadas, 106 (88,3% foram positivas para coliformes totais e 48 (40,0%, para coliformes fecais. Não houve positividade para aeromonas móveis. Os dados obtidos indicam que a maioria das amostras analisadas não atende ao padrão de potabilidade, em virtude da presença de coliformes totais em 100 mL. A presença desse tipo de coliformes não parece estar relacionada com influências sazonais, enquanto a incidência de coliformes fecais apresenta correlação com os indices pluviométricos das etapas de amostragem: os meses de menor índice coincidem com menor positividade desse indicador bacteriano e os meses com índice mais alto, com maior porcentagem de positividade.

    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

    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.

    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)

Each image displays data from a different spectral region, and illustrates the complementary nature of surface compositional information available as a function of wavelength. This image displays visible and near infrared bands 3, 2, and 1 in red, green, and blue (RGB). Vegetation appears red, snow and dry salt lakes are white, and exposed rocks are brown, gray, yellow and blue. Rock colors mainly reflect the presence of iron minerals, and variations in albedo. Figure 1 displays short wavelength infrared bands 4, 6, and 8 as RGB. In this wavelength region, clay, carbonate, and sulfate minerals have diagnostic absorption features, resulting in distinct colors on the image. For example, limestones are yellow-green, and purple areas are kaolinite-rich. Figure 2 displays thermal infrared bands 13, 12 and 10 as RGB. In this wavelength region, variations in quartz content appear as more or less red; carbonate rocks are green, and mafic volcanic rocks are purple. The image is located at 36.8 degrees north latitude and 117.7 degrees west longitude. The U.S. science team is located at NASA's Jet Propulsion Laboratory, Pasadena, Calif.

    2015-04-01

    Portugal is one of the major fire-prone European countries, mainly due to its favourable climatic, topographic and vegetation conditions. 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

    Millipedes play an important role in the decomposition of organic matter in the subterranean environment. Despite the existence of several cave-adapted species of millipedes in adjacent geographic areas, their study has been largely ignored in Portugal. Over the last decade, intense fieldwork...... in caves of the mainland and the island of Madeira has provided new data about the distribution and diversity of millipedes. A review of millipedes from caves of Portugal is presented, listing fourteen species belonging to eight families, among which six species are considered troglobionts....... The distribution of millipedes in caves of Portugal is discussed and compared with the troglobiont biodiversity in the overall Iberian Peninsula and the Macaronesian archipelagos....

    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.

    En este trabajo presentamos la primera evidencia de arte mueble paleolítico en el sur de Portugal: dos plaquetas de pizarra procedentes de niveles solutrenses del yacimiento de Vale Boi, zona occidental del Algarve (Portugal. La primera de las piezas es una pequeña placa (14,6 × 8,1 mm que presenta sobre una de sus caras un ideomorfo grabado. La segunda (8 × 5 cm cuenta con una superficie ocupada por óxido de hierro natural de color amarillento, tiene claros indicios de extracción de mineral para producir colorantes. En la superficie opuesta han sido grabados tres uros y una posible cierva. El estilo y secuencia de los grabados apuntan a un solo artista. Las características estilísticas de los zoomorfos concuerdan bien con los rasgos comunes del arte del ciclo Gravetiense final y Solutrense antiguo del País Valenciano, Andalucía y Valle de Côa (Portugal. Esta afinidad sintoniza asimismo con las fechas AMS de los niveles solutrenses de Vale Boi, datados entre ca. 20.500 y 19.500 BP.

    Full Text Available In Portugal fish farming has expanded very rapidly in the last decade, with trout, mullet, cuttlefish, seabream, eel, salmon and prawns being intensively reared in artificial ponds. A questionnaire was sent to all known fish farmers to assess the effect of predation, especially by otters; no compensation scheme exists in Portugal. This paper discusses the results of this exercise. It is suggested that fish farmers need to look beyond economic and technological aspects of aquaculture and consider the wider environmental impact of their activities.

    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.

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.

    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.

  13. 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

    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

    Neurocysticercosis (NCC) is the most common cause of acquired epilepsy in resource-poor countries. We report the case of a 24-year-old woman born and residing in Guinea-Bissau, who was transferred to Portugal two months after the onset of a possible meningitis (fever, headache, seizures, and coma) that did not respond to antibiotic treatment. The diagnosis of NCC was confirmed by MR imaging, which showed multiple lesions compatible with cysticercus, and by polymerase chain reaction (PCR) of the cerebrospinal fluid. After 28 days on albendazole and dexamethasone without improvement, she was started on praziquantel, which she completed in six weeks with progressive recovery.

    In this paper we find that public investment in durable goods has a positive effect on long-term economic performance in Portugal. We also find that these positive effects are not strong enough for public investment to pay for itself in the form of future tax revenues. Therefore, cuts in public investment in durable goods, although costly in terms of long-term economic performance seem to be an effective way of alleviating pressure on the public budget. It is important to note, however, that ...

    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.

    Although amphitheater-shaped valley heads can be cut by groundwater flows emerging from springs, recent geological evidence suggests that other processes may also produce similar features, thus confounding the interpretations of such valley heads on Earth and Mars. To better understand the origin of this topographic form we combine field observations, laboratory experiments, analysis of a high-resolution topographic map, and mathematical theory to quantitatively characterize a class of physical phenomena that produce amphitheater-shaped heads. The resulting geometric growth equation accurately predicts the shape of decimeter-wide channels in laboratory experiments, 100-meter wide valleys in Florida and Idaho, and kilometer wide valleys on Mars. We find that whenever the processes shaping a landscape favor the growth of sharply protruding features, channels develop amphitheater-shaped heads with an aspect ratio of pi.

    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). The colors in this image represent the following radar channels and polarizations: red is L-band, horizontally transmitted and received; green is L-band, horizontally transmitted and vertically received; and blue is C-band, horizontally transmitted and vertically received.

    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.

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

    Directory of Open Access Journals (Sweden)

    Catarina Reis Oliveira

    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.

  8. Valley-contrasting orbital angular momentum in photonic valley crystals

    Chen, Xiaodong; Dong, Jianwen

    2016-01-01

    Valley, as a degree of freedom, has been exploited to realize valley-selective Hall transport and circular dichroism in two-dimensional layered materials. On the other hand, orbital angular momentum of light with helical phase distribution has attracted great attention for its unprecedented opportunity to optical communicagtions, atom trapping, and even nontrivial topology engineering. Here, we reveal valley-contrasting orbital angular momentum in all-dielectric photonic valley crystals. Selective excitation of valley chiral bulk states is realized by sources carrying orbital angular momentum with proper chirality. Valley dependent edge states, predictable by nonzero valley Chern number, enable to suppress the inter-valley scattering along zigzag boundary, leading to broadband robust transmission in Z-shape bend without corner morphological optimization. Our work may open up a new door towards the discovery of novel quantum states and the manipulation of spin-orbit interaction of light in nanophotonics.

    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.

    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 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

    Throughout its history the Lower Tagus Valley (LTV) has been struck by several earthquakes which produced important material damage and loss of lives: The 1st of November 1755 Lisbon earthquake and the 1969 earthquake (Mw=7.3), located in the SW Iberia Margin and the 1344, 1531 and 1909 (M= 6 to 7) with epicenter located inside the LTV basin. Since this region is the most highly populated region in Portugal, it is expected that an earthquake of similar magnitude of those that have occurred in the past will cause an enormous destruction and casualties. This fact makes LTV a high priority area for earthquake research in Portugal.

    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

    2016-04-01

    The work focuses the evaluation of landslide susceptibility in Douro Region agricultural terraces, supported by dry stone walls and earth embankments, using two physically based models. The applied models, SHALSTAB (Montgomery et al.,1994; Dietrich et al., 1995) and SINMAP (PACK et al., 2005), combine an infinite slope stability model with a steady state hydrological model, and both use the following geophysical parameters: cohesion, friction angle, specific weight and soil thickness. The definition of the contributing areas is different in both models. The D∞ methodology used by SINMAP model suggests a great influence of the terraces morphology, providing a much more diffuse flow on the internal flow modelling. The MD8 used in SHALSTAB promotes an important degree of flow concentration, representing an internal flow based on preferential paths of the runoff as the areas more susceptible to saturation processes. The model validation is made through the contingency matrix method (Fawcett, 2006; Raia et al., 2014) and implies the confrontation with the inventory of past landslides. The True Positive Rate shows that SHALSTAB classifies 77% of the landslides on the high susceptibility areas, while SINMAP reaches 90%. The SINMAP has a False Positive Rate (represents the percentage of the slipped area that is classified as unstable but without landslides) of 83% and the SHALSTAB has 67%. The reliability (analyzes the areas that were correctly classified on the total area) of SHALSTAB is better (33% against 18% of SINMAP). Relative to Precision (refers to the ratio of the slipped area correctly classified over the whole area classified as unstable) SHALSTAB has better results (0.00298 against 0.00283 of SINMAP). It was elaborate the index TPR/FPR and better results obtained by SHALSTAB (1.14 against 1.09 of SINMAP). SHALSTAB shows a better performance in the definition of susceptibility most prone areas to instability processes. One of the reasons for the difference of predictive capacity of the models is related with the construction methods of contributory areas. The SHALSTAB susceptibility map shows better discrimination of the unstable areas, which is important to the estates decision makers in order to organize the priority of the hazard mitigation process.

    In 1998, Silicon Valley companies produced 41 IPOs, which by January 1999 had a combined market capitalization of $27 billion--that works out to $54,000 in new wealth creation per worker in a single year. Multiply the number of employees in your company by $54,000. Did your business create that much new wealth last year? Half that amount? It's not a group of geniuses generating such riches. It's a business model. In Silicon Valley, ideas, capital, and talent circulate freely, gathering into whatever combinations are most likely to generate innovation and wealth. Unlike most traditional companies, which spend their energy in resource allocation--a system designed to avoid failure--the Valley operates through resource attraction--a system that nurtures innovation. In a traditional company, people with innovative ideas must go hat in hand to the guardians of the old ideas for funding and for staff. But in Silicon Valley, a slew of venture capitalists vie to attract the best new ideas, infusing relatively small amounts of capital into a portfolio of ventures. And talent is free to go to the companies offering the most exhilarating work and the greatest potential rewards. It should actually be easier for large, traditional companies to set up similar markets for capital, ideas, and talent internally. After all, big companies often already have extensive capital, marketing, and distribution resources, and a first crack at the talent in their own ranks. And some of them are doing it. The choice is yours--you can do your best to make sure you never put a dollar of capital at risk, or you can tap into the kind of wealth that's being created every day in Silicon Valley.

  10. Inversion of ambient seismic noise HVSR to evaluate velocity and structural models of the Lower Tagus Basin, Portugal

    During its history, several significant earthquakes have shaken the Lower Tagus Valley (Portugal). These earthquakes were destructive; some strong earthquakes were produced by large ruptures in offshore structures located southwest of the Portuguese coastline, and other moderate earthquakes were produced by local faults. In recent years, several studies have successfully obtained strong-ground motion syntheses for the Lower Tagus Valley using the finite difference method. To confirm the velocity model of this sedimentary basin obtained from geophysical and geological data, we analysed the ambient seismic noise measurements by applying the horizontal to vertical spectral ratio (HVSR) method. This study reveals the dependence of the frequency and amplitude of the low-frequency (HVSR) peaks (0.2-2 Hz) on the sediment thickness. We have obtained the depth of the Cenozoic basement along a profile transversal to the basin by the inversion of these ratios, imposing constraints from seismic reflection, boreholes, seismic sounding and gravimetric and magnetic potentials. This technique enables us to improve the existing three-dimensional model of the Lower Tagus Valley structure. The improved model will be decisive for the improvement of strong motion predictions in the earthquake hazard analysis of this highly populated basin. The methodology discussed can be applied to any other sedimentary basin.

    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.

    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.

    Directory of Open Access Journals (Sweden)

    2013-02-01

    Full Text Available Central Portugal, delimited by the Douro river to the north and the Mondego to the south, is the second densest region of megalithic monuments in the country. The Neolithic archaeological record indicates seasonal transhumance between higher pastures in the summer and lower grounds in the winter. The monuments are found in lower ground and it has been suggested that they were built during the winter occupation of their surroundings. The astronomical orientation of their entrances lends further support to this hypothesis. A recent survey of the orientation of the chambers and corridors of these dolmens, conducted by the author, found good agreement with prior surveys, but also demonstrated that other interpretations are possible. This paper presents an update on the survey, including extra sites surveyed in the spring of 2011, as well as the GIS confirmation of all horizon altitudes that couldn’t be empirically measured. The megalithic nucleus of Carregal do Sal, on the Mondego valley, is then looked at in more detail. It is found that there is a preference for the orientation of dolmens towards Star Mountain Range in-line with the topographic arguments of landscape archaeology. In addition, it was found that the topography also marks the rise of particular red stars, Betelgeuse and Aldebaran, during the period of megalithic building, at the onset of spring marking the transition from low ground to the high pastures. This hypothesis finds further support from toponymic folktales that explain the origin of the name of the mountain range.

    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.

    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.

  8. 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)

  2. 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.

  18. 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.

This paper presents an assessment of several elements for that debate, and the common resources that can define the area as a common tourist destination. A design model is also provided, which can enable territory planning through the appraisal of those...

    2014-11-01

    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.

    Full Text Available Anouk Speets1, Judith Wolleswinkel1, Cristina Cardoso21Pallas health research and consultancy, Rotterdam, the Netherlands; 2GlaxoSmithKline, Algés, PortugalAbstract: This study aimed to estimate the resource consumption and societal impact of otitis media (OM in children younger than five years of age 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

    Science.gov (United States)

    Prati, Enrico

    2011-10-01

    In analogy to the Coulomb and the Pauli spin blockade, based on the electrostatic repulsion and the Pauli exclusion principle respectively, the concept of valley blockade in Silicon nanostructures is explored. The valley parity operator is defined. Valley blockade is determined by the parity conservation of valley composition eigenvectors in quantum transport. A Silicon quantum changeover switch based on a triple of donor quantum dots capable to separate electrons having opposite valley parity by virtue of the valley parity conservation is proposed. The quantum changeover switch represents a novel kind of hybrid quantum based classical logic device.

  16. Valley evolution by meandering rivers

    Science.gov (United States)

    Limaye, Ajay Brian Sanjay

    Fluvial systems form landscapes and sedimentary deposits with a rich hierarchy of structures that extend from grain- to valley scale. Large-scale pattern formation in fluvial systems is commonly attributed to forcing by external factors, including climate change, tectonic uplift, and sea-level change. Yet over geologic timescales, rivers may also develop large-scale erosional and depositional patterns that do not bear on environmental history. This dissertation uses a combination of numerical modeling and topographic analysis to identify and quantify patterns in river valleys that form as a consequence of river meandering alone, under constant external forcing. Chapter 2 identifies a numerical artifact in existing, grid-based models that represent the co-evolution of river channel migration and bank strength over geologic timescales. A new, vector-based technique for bank-material tracking is shown to improve predictions for the evolution of meander belts, floodplains, sedimentary deposits formed by aggrading channels, and bedrock river valleys, particularly when spatial contrasts in bank strength are strong. Chapters 3 and 4 apply this numerical technique to establishing valley topography formed by a vertically incising, meandering river subject to constant external forcing---which should serve as the null hypothesis for valley evolution. In Chapter 3, this scenario is shown to explain a variety of common bedrock river valley types and smaller-scale features within them---including entrenched channels, long-wavelength, arcuate scars in valley walls, and bedrock-cored river terraces. Chapter 4 describes the age and geometric statistics of river terraces formed by meandering with constant external forcing, and compares them to terraces in natural river valleys. The frequency of intrinsic terrace formation by meandering is shown to reflect a characteristic relief-generation timescale, and terrace length is identified as a key criterion for distinguishing these

    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.

  7. Determinants of birth weight in Portugal: 1988 to 2011.

    Fuster, Vicente; Santos, Carlota

    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.

  8. Atmospheric turbidity over Kathmandu valley

    Science.gov (United States)

    Sapkota, Balkrishna; Dhaubhadel, Rajan

    The atmosphere of Kathmandu Valley has been investigated by using Sunphotometer and Nephelometer during the pre-monsoon period of 1999. The atmospheric turbidity parameters (extinction coefficient for 500 nm wavelength τAG and Angstrom coefficient β) are found high in the morning and show decreasing trends from morning to late afternoon on average. Vertical dispersion of pollutants and increasing pollutant flushing rate by increasing wind speed from morning to late afternoon is the cause for this decreasing trend of turbidity over the valley. Being surrounded by high hills all around the valley, horizontal exit of pollutants without vertical dispersion is not possible. The scattering coefficient bscat of aerosols in ground level troposphere is also found high in the morning, which decreases and becomes minimum during afternoon. During late afternoon, bscat again shows a slightly increasing trend. The reason is the increasing vehicular emission during late afternoon rush period. The average values of Angstrom exponent α, β, τAG and bscat are found to be 0.624±0.023, 0.299±0.009, 0.602±0.022 and 0.353±0.014 km -1, respectively. About 76.8% of the observed values of β lie above 0.2 indicating heavy particulate pollution in the valley. A comparison of observed values of turbidity parameters with other major cities of the world shows that Kathmandu is as polluted as cities like Jakarta, Kansas, Beijing, Vienna, etc.

    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

    An outbreak of porcine epidemic diarrhea virus (PEDV) in the South of Portugal in January 2015 and the spread of PEDV northwards in the territory are described. Comparative analysis of the amplified sequences showed a very high (99.0%) identity with the PEDV variant most recently reported in the United States and also show complete (100%) identity to the strains recently reported in Germany, supporting the hypothesis that a unique strain is currently circulating in Europe. The origin of this PEDV variant still needs to be elucidated and further studies in the remaining European countries may contribute to the knowledge.

  10. 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

    We propose to realize adiabatic topological spin and valley pumping by using silicene, subject to the modulation of an in-plane ac electric field with amplitude Ey and a vertical electric field consisting of an electrostatic component and an ac component with amplitudes and . By tuning and , topological valley pumping or spin-valley pumping can be achieved. The low-noise valley and spin currents generated can be useful in valleytronic and spintronic applications. Our work also demonstrates that bulk topological spin or valley pumping is a general characteristic effect of two-dimensional topological insulators, irrelevant to the edge state physics.

    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.

    2013-06-01

    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.

    2011-12-01

    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.

    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

    2012-03-01

    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.

  16. 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.

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.

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.

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.

    The valley-dependent energy band and transport property of graphene under a periodic magnetic-strained field are studied, where the time-reversal symmetry is broken and the valley degeneracy is lifted. The considered superlattice is composed of two different barriers, providing more degrees of freedom for engineering the electronic structure. The electrons near the K and K' valleys are dominated by different effective superlattices. It is found that the energy bands for both valleys are symmetric with respect to ky=-(AM+ξ AS) /4 under the symmetric superlattices. More finite-energy Dirac points, more prominent collimation behavior, and new crossing points are found for K' valley. The degenerate miniband near the K valley splits into two subminibands and produces a new band gap under the asymmetric superlattices. The velocity for the K' valley is greatly renormalized compared with the K valley, and so we can achieve a finite velocity for the K valley while the velocity for the K' valley is zero. Especially, the miniband and band gap could be manipulated independently, leading to an increase of the conductance. The characteristics of the band structure are reflected in the transmission spectra. The Dirac points and the crossing points appear as pronounced peaks in transmission. A remarkable valley polarization is obtained which is robust to the disorder and can be controlled by the strain, the period, and the voltage.

    Full Text Available Ao longo das últimas décadas, o número de estrangeiros residentes em Portugal aumentou de forma expressiva. 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. Verificaram-se igualmente algumas diferenças nos padrões de matrimônio entre os sexos, bem como uma tendência para a diminuição da importância dos casamentos mistos, em especial entre os homens.A lo largo de las últimas décadas, el número de extranjeros residentes en Portugal aumentó de forma expresiva.

  8. 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

    In this true-color MODIS image from October 23, 2001, the semi-arid Tibetan Plateau (upper left) meets up with the Himalayas to the south. From the heights of the Himalayas, snow-covered on their northern flanks, and lush with vegetation to the south, numerous rivers, brown with churned up sediment, flow into the valley of the Brahmaputra River in Assam, India. The Brahmaputra turns southward at the border of Bangladesh and is soon joined by the Ganges River, flowing in from image left. The mighty river splits into numerous channels as it runs out toward the Bay of Bengal, giving the region the name 'Mouths of the Ganges.' Vast amounts of sediment are being emptied into the Bay by the river, and greenish blue swirls could be a mixture of sediment and phytoplankton.

  11. 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

  12. 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 fin de comprobar si la percepción de las causas de la evasión fiscal son generalizables transculturalmente, este artículo presenta una investigación realizada en Portugal utilizando las mismas atribuciones causales usadas en la investigación española. A una muestra de 497 hombres y mujeres portugueses, de diferentes puestos de trabajo, se les preguntó acerca de sus percepciones causales de la evasión fiscal. Se llevó a cabo un análisis factorial y los resultados mostraron una estructura factorial que reproduce la estructura factorial española. Los coeficientes de congruencia confirmaron la similitud de las dos estructuras. Estos resultados confirmaron que las dos dimensiones pueden explicar la estructura de la percepción de las causas de la evasión fiscal.

    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.

  11. 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.

    Silvana Sidney Costa Santos

    2013-09-01

    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.

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.

    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.

  17. Sea urchins, their predators and prey in SW Portugal

    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

  19. 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

    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 “Anos de Ruptura”, a década de 1960 marca, em Portugal, um importante ponto de viragem na transição para a democracia. A “derrota” de Humberto Delgado nas eleições presidenciais de 1958, o deflagrar da Guerra Colonial, o crescente êxodo rural e a emigração económica e política, as lutas estudantis, o Marcelismo e a abertura ao investimento exterior, assim como a generalização de importantes benefícios sociais, como o direito a férias pagas, testemunham profundas transformações na sociedade portuguesa, com inevitáveis repercussões na organização do território. A par da suburbanização dos principais centros populacionais do país, o advento de um turismo de massas será o principal motor dessa nova ordem espacial, assistindo‑se ao ensaio de novos modelos urbanísticos e arquitectónicos que iriam revolucionar o panorama disciplinar nacional. É sobre o impacto do fenómeno turístico na actividade dos arquitectos portugueses e, consequentemente, na sua relação com a sociedade e os mecanismos de produção capitalista dos anos sessenta que o presente artigo se propõe reflectir, na perspectiva de relançar o debate, então adiado, acerca das implicações físicas e culturais do lazer na colonização da paisagem.

    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.

    Full Text Available During the second half of the nineteenth century and early twentieth century the discipline of secondary mathematics was gradually built in Portugal and certified teachers, textbooks, programs, special teaching techniques emerge. 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.

    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)

  17. Pleistocene and Holocene geomorphological development in the Algarve, southern Portugal

    Science.gov (United States)

    Chester, David K.

    2012-06-01

    A detailed chronological framework for Pleistocene and Holocene geomorphology and landscape evolution in the Algarve is proposed. With regards to the Pleistocene, attention has focused on the origin, dating and stratigraphy of the Ludo Formation. Subsuming the classifications of earlier writers, it is now proposed that during the Pliocene a marine transgression occurred across a tectonically controlled basin that was constrained by the mountains of the Algarve interior to the north. Fluvial sands were then deposited in a regressive phase during the late Pliocene/early Pleistocene, while braided streams operating under semi-arid conditions subsequently laid down sands and gravels in the middle and upper Pleistocene. Lying unconformably over the Ludo Formation is an alluvial deposit (Odiáxere gravels and Loulé sands) of late Pleistocene/early Holocene date that is found within the river valleys of the Algarve. In the early-Holocene (ca.10, 000-ca.7000 BP) and early late-Holocene (ca.5000-ca.3000 BP), the situation in the Algarve was one of climatic amelioration (i.e., warmer and wetter conditions), rising sea levels, vegetation colonization, soil development and towards the end of this period trenching of the Odiáxere gravels and Loulé sands. From ca.3000 BP evidence is abundant that humans became important geomorphological agents either acting on their own or in combination with climatic factors. From around 5000 BP, conditions became dryer and, between ca.3000 BP and ca.700 BP, clearance of land by pre-Roman, Roman, and especially Islamic agricultural settlers caused widespread erosion and the deposition of extensive spreads of topsoil dominated sediment within river valleys (i.e., the Holocene terrace) and in coastal estuaries. A period followed up to 1900 CE when agricultural practices were less damaging to the soil, erosion was reduced and the Holocene terrace - together with coastal and estuarine deposits - was incised. In the past century and under

    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. Résumé.

    Machadinho, Ana; Figueiredo, Fernando; Pereira, Alcides

    2015-04-01

    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

    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

  3. 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.

  1. Palaeoseismology of the Vilariça segment of the Manteigas-Bragança fault in northeastern Portugal

    Science.gov (United States)

    Rockwell, Thomas; Fonseca, Joao; Madden, Chris; Dawson, Tim; Owen, Lewis A.; Vilanova, Susana; Figueiredo, Paula

    2009-01-01

    The Manteigas-Bragança fault is a major, 250-km-long, NNE-striking, sinistral strike-slip structure in northern Portugal. This fault has no historical seismicity for large earthquakes, although it may have generated moderate (M5+) earthquakes in 1751 and 1858. Evidence of continued left horizontal displacement is shown by the presence of Cenozoic pull-apart basins as well as late Quaternary stream deflections. To investigate its recent slip history, a number of trenches were excavated at three sites along the Vilariça segment, north and south of the Douro River. At one site at Vale Meão winery, the occurrence of at least two and probably three events in the past 14.5 ka was determined, suggesting an average return period of about 5–7 ka. All three events appear to have occurred as a cluster in the interval between 14.5 and 11 ka, or shortly thereafter, suggesting a return period of less than 2 ka between events within the cluster. In the same area, a small offset rill suggests 2–2.5 m of slip in the most recent event and about 6.1 m after incision below a c. 16 ka alluvial fill event along the Douro River. At another site along the Vilariça River alluvial plain, NE of the Vale Meão site, several trenches were excavated in late Pleistocene and Holocene alluvium, and exposed the fault displacing channel deposits dated to between 18 and 23 ka. In a succession of closely spaced parallel cuts and trenches, the channel riser was traced into and across the fault to resolve c. 6.5 m of displacement after 18 ka and c. 9 m of slip after c. 23 ka. These observations yield a slip rate of 0.3–0.5 mm/a, which is consistent with earlier estimates. Combining the information on timing at Vale Meão winery and displacement at Vilariça argues for earthquakes in the M7+ range, with coseismic displacements of 2–3 m. This demonstrates that there are potential seismic sources in Portugal that are not associated with the 1755 Lisbon earthquake or the Tagus Valley, and

  2. Trends in gastric cancer mortality and in the prevalence of Helicobacter pylori infection in Portugal.

    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.

  3. Stably Stratified Flow in a Shallow Valley

    Science.gov (United States)

    Mahrt, L.

    2016-07-01

    Stratified nocturnal flow above and within a small valley of approximately 12-m depth and a few hundred metres width is examined as a case study, based on a network of 20 sonic anemometers and a central 20-m tower with eight levels of sonic anemometers. Several regimes of stratified flow over gentle topography are conceptually defined for organizing the data analysis and comparing with the existing literature. In our case study, a marginal cold pool forms within the shallow valley in the early evening but yields to larger ambient wind speeds after a few hours, corresponding to stratified terrain-following flow where the flow outside the valley descends to the valley floor. The terrain-following flow lasts about 10 h and then undergoes transition to an intermittent marginal cold pool towards the end of the night when the larger-scale flow collapses. During this 10-h period, the stratified terrain-following flow is characterized by a three-layer structure, consisting of a thin surface boundary layer of a few metres depth on the valley floor, a deeper boundary layer corresponding to the larger-scale flow, and an intermediate transition layer with significant wind-directional shear and possible advection of lee turbulence that is generated even for the gentle topography of our study. The flow in the valley is often modulated by oscillations with a typical period of 10 min. Cold events with smaller turbulent intensity and duration of tens of minutes move through the observational domain throughout the terrain-following period. One of these events is examined in detail.

    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 RESUMEN: Las economías de Castilla y Portugal durante la segunda mitad del siglo XVI estaban estrechamente ligadas por vínculos financieros. 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.

  19. An overview of the RAIDEN project: a study of lightning in Portugal

    Fragoso, Marcelo; Leite, Solange; Sousa, João; Correia, Sandra; Reis, Margarida; Santos, João Andrade

    2013-04-01

    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.

  1. Disastrous floods and landslides in Portugal in the 20th century

    Quaresma, Ivânia; Zêzere, José Luis

    2010-05-01

    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

  11. Pumpernickel Valley Geothermal Project Thermal Gradient Wells

    Energy Technology Data Exchange (ETDEWEB)

    Z. Adam Szybinski

    2006-01-01

    The Pumpernickel Valley geothermal project area is located near the eastern edge of the Sonoma Range and is positioned within the structurally complex Winnemucca fold and thrust belt of north-central Nevada. A series of approximately north-northeast-striking faults related to the Basin and Range tectonics are superimposed on the earlier structures within the project area, and are responsible for the final overall geometry and distribution of the pre-existing structural features on the property. Two of these faults, the Pumpernickel Valley fault and Edna Mountain fault, are range-bounding and display numerous characteristics typical of strike-slip fault systems. These characteristics, when combined with geophysical data from Shore (2005), indicate the presence of a pull-apart basin, formed within the releasing bend of the Pumpernickel Valley – Edna Mountain fault system. A substantial body of evidence exists, in the form of available geothermal, geological and geophysical information, to suggest that the property and the pull-apart basin host a structurally controlled, extensive geothermal field. The most evident manifestations of the geothermal activity in the valley are two areas with hot springs, seepages, and wet ground/vegetation anomalies near the Pumpernickel Valley fault, which indicate that the fault focuses the fluid up-flow. There has not been any geothermal production from the Pumpernickel Valley area, but it was the focus of a limited exploration effort by Magma Power Company. In 1974, the company drilled one exploration/temperature gradient borehole east of the Pumpernickel Valley fault and recorded a thermal gradient of 160oC/km. The 1982 temperature data from five unrelated mineral exploration holes to the north of the Magma well indicated geothermal gradients in a range from 66 to 249oC/km for wells west of the fault, and ~283oC/km in a well next to the fault. In 2005, Nevada Geothermal Power Company drilled four geothermal gradient wells, PVTG-1

    In crystals, energy band extrema in momentum space can be identified by a valley index. The internal quantum degree of freedom associated with valley pseudospin indices can act as a useful information carrier, analogous to electronic charge or spin. Interest in valleytronics has been revived in recent years following the discovery of atomically thin materials such as graphene and transition metal dichalcogenides. However, the valley coherence time--a crucial quantity for valley pseudospin manipulation--is difficult to directly probe. In this work, we use two-dimensional coherent spectroscopy to resonantly generate and detect valley coherence of excitons (Coulomb-bound electron-hole pairs) in monolayer WSe2 (refs ,). The imposed valley coherence persists for approximately one hundred femtoseconds. We propose that the electron-hole exchange interaction provides an important decoherence mechanism in addition to exciton population recombination. This work provides critical insight into the requirements and strategies for optical manipulation of the valley pseudospin for future valleytronics applications.

  14. Valley-selective optical Stark effect in monolayer WS2

    Science.gov (United States)

    Gedik, Nuh

    Monolayer semiconducting transition-metal dichalcogenides (TMDs) have a pair of valleys that, by time-reversal symmetry, are energetically degenerate. Lifting the valley degeneracy in these materials is of great interest because it would allow for valley specific band engineering and offer additional control in valleytronic applications. In this talk, I will show that circularly polarized light, which breaks time-reversal symmetry, can be used to lift the valley degeneracy by means of the optical Stark effect. We demonstrate that this effect is capable of raising the exciton level in monolayer TMD WS2 by as much as 18 meV in a controllable valley-selective manner. The resulting energy shift is extremely large, comparable to the shift that would be obtained using a very high magnetic field (approximately 100 Tesla). These results offer a novel way to control valley degree of freedom, and may provide a means to realize new valley-selective Floquet topological state of matter.

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

    Directory of Open Access Journals (Sweden)

    Daniela Dias

    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.

  16. 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.

    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.

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

    Directory of Open Access Journals (Sweden)

    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.

    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)

  3. 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.

Parte-se da interpretação do discurso educacional que à época seria assumido particularmente por um setor específico da imprensa, constituído por revistas e periódicos que tinham intenção de esclarecimento e instrução das populações. Tais revistas propunham, portanto, o investimento social na escola primária como uma maneira de reconstituir uma dada vocação perdida da nacionalidade portuguesa. De alguma maneira, tratava-se de inserir Portugal na desejada modernidade, mediante a criação do rito escolar, ou daquilo que já se caracterizou por forma escolar de socialização.  Abstract This paper looks for approaching the education situation and, in particular, of the primary school in Portugal during the first half of the 19th century, coming to light the way of thinking that the press had about the same act of schooling. Starting from the interpretation of the educational discourse that, in that epoch, would be assumed, in particular, by a specific sector of the press, constituted by magazines and periodicals wich had the intention of clearness and instruction of the populations. Such magazines were proposing, consequently, the social investiment in the primary school as a manner to rebuild the inborn lost vocation of the portuguese nationality. In any way, the objective was to introduce Portugal in the desired modernity, by means of the schooling rite, or of what that had already be characterized through socialization schoolinhg forme.

    The increasing popularity of increasing block tariffs (IBT) for water is reflected in Portugal by a virtually universal implementation for residential use. IBT are often supported as a good tool for achieving the goals of equity, water conservation and revenue neutrality but seldom have they been grounded on efficiency justifications. We test the conditions derived by Roseta-Palma and Monteiro (2008) for IBT to be a second-best pricing practice under water scarcity and budget balancing constr...

  13. Climate change and pollutant emissions impacts on air quality in 2050 over Portugal

    Changes in climate and air pollutant emissions will affect future air quality from global to urban scale. In this study, regional air quality simulations for historical and future periods are conducted, with CAMx version 6.0, to investigate the impacts of future climate and anthropogenic emission projections on air quality over Portugal and the Porto metropolitan area in 2050. The climate and the emission projections were derived from the Representative Concentrations Pathways (RCP8.5) scenario. Modelling results show that climate change will impact NO2, PM10 and O3 concentrations over Portugal. The NO2 and PM10 annual means will increase in Portugal and in the Porto municipality, and the maximum 8-hr daily O3 value will increase in the Porto suburban areas (approximately 5%) and decrease in the urban area (approximately 2%). When considering climate change and projected anthropogenic emissions, the NO2 annual mean decreases (approximately 50%); PM10 annual mean will increase in Portugal and decrease in Porto municipality (approximately 13%); however PM10 and O3 levels increase and extremes occur more often, surpassing the currently legislated annual limits and displaying a higher frequency of daily exceedances. This air quality degradation is likely to be related with the trends found for the 2046-2065 climate, which implies warmer and dryer conditions, and with the increase of background concentrations of ozone and particulate matter. The results demonstrate the need for Portuguese authorities and policy-makers to design and implement air quality management strategies that take climate change impacts into account.

    The increasing number of new cases of cancer highlights the relevance of primary prevention for cancer control, which is influenced, among other factors, by the population’s health-related knowledge. Therefore, we aimed to describe cancer-related knowledge in Portugal, including perception of risk, awareness of cancer causes and preventive behaviours. We evaluated 1624 Portuguese-speaking dwellers, aged between 16 and 79 years, through face-to-face interviews conducted using a structured questionnaire. We computed adjusted (sex, age, education) regression coefficients and prevalence ratios, using linear and Poisson regression, respectively, to quantify associations with cancer-specific knowledge. The proportions of nonresponse ranged from 13.4 to 63.5% for the most frequent cancer in Portugal and the leading cause of cancer, respectively. The mean of the estimated lifetime risk of cancer in the Portuguese population was 37.0%. A total of 47.5% of the respondents identified breast cancer as the most frequent in Portugal, 72.0% named lifestyles as the leading cause of cancer and 40.2% selected not smoking as the most important preventive behaviour. Lower levels of education were associated with higher proportions of nonresponse, but not consistently with inaccurate knowledge. Men provided lower estimates of the lifetime risk of cancer, indicated breast cancer less frequently and more often lung cancer as the most frequent, and were more likely to select not smoking as the most important preventive behaviour. The present study provides relevant data on knowledge of cancer prevention, which may be used for the planning and evaluation of awareness-raising and primary prevention interventions in Portugal.

    Lopes, Margarida; Fernandes, Graca

    2011-01-01

    Unemployment rates among Portuguese Higher Education (HE) graduates have been rising. This trend becomes quite obvious when we compare Portugal and other European Member States whose labor markets have been facing similar difficulties. In fact, Portuguese graduates are not only more prone to facing unemployment but they are also enduring long term unemployment as a result of the current unemployment crisis. Among the main reasons for this situation is the mismatch between the supply and d...

    2013-04-01

    The present work is carried out 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)", and is devoted to the study of hydro-meteorological extreme events during the last 350 years, in order to understand how they have changed in time and compare them with current analogues. More specifically, the results selected to this presentation will focus on some hydro-meteorological extreme events of the 18th century, like severe droughts, heavy precipitation episodes and windstorms. One of the most noteworthy events was the winterstorm Bárbara (3rd to 6th December 1739), already studied in prior investigations (Taborda et al, 2004; Pfister et al, 2010), a devastating storm with strong impacts in Portugal caused by violent winds and heavy rainfall. Several other extreme events were detected by searching different documentary archives, including individual, administrative and ecclesiastic sources. Moreover, a more detailed insight to the 1783-1787 period will be made with regard the Lisbon region, taking into consideration the availability of information for daily meteorological observations as well as documentary evidences, like descriptions from Gazeta de Lisboa, the periodic with more continuous publication in the 18thcentury.

  13. La expulsión de los jesuitas de Portugal en la “era pombalina”

    Directory of Open Access Journals (Sweden)

    Vivanco Díaz, Borja

    2014-04-01

    Full Text Available The Jesuits were expelled from Portugal in 1759 as a consequence of Regalian policy of enlightened despotism, which had been wholeheartedly accepted by Marquis of Pombal, prime-minister under the King Joseph I. Accusations of inciting the Guarani people to rise up against “The Treaty of the borders”, on the one hand, and of conspiring in the assassination attempt against King Joseph I, on the other, supported the decision to force the Jesuits into exile. However, neither allegation has been ever proven, rather they were the result of Pombal’s campaign against Saint Ignatius of Loyola’s order. The ultimate outcome of the expulsion of the Jesuits was the diminished influence of Catholic Church, thus encourating the introduction of new Enlightenment ideas in Portugal.Los jesuitas fueron expulsados de Portugal en 1759 como consecuencia de la política “regalista” del “despotismo ilustrado” y a la que se había adherido sin reservas el Marqués de Pombal, primer ministro del rey José I. Las acusaciones de instigar a los guaraníes a rebelarse contra el Tratado de los Límites, por un lado, y de conspirar en la organización del atentado frustrado contra la vida de José I, por otro, sirvieron de argumentos para provocar el exilio de la Compañía de Jesús. Sin embargo, ninguna de las dos acusaciones ha podido ser nunca probada y respondieron más bien a la campaña “pombalina” contra la orden de Ignacio de Loyola. Como resultado final, la expulsión de los jesuitas aminoró la influencia de la Iglesia Católica y favoreció la introducción en Portugal de las nuevas ideas de la Ilustración.

    The increasing number of new cases of cancer highlights the relevance of primary prevention for cancer control, which is influenced, among other factors, by the population's health-related knowledge. Therefore, we aimed to describe cancer-related knowledge in Portugal, including perception of risk, awareness of cancer causes and preventive behaviours. We evaluated 1624 Portuguese-speaking dwellers, aged between 16 and 79 years, through face-to-face interviews conducted using a structured questionnaire. We computed adjusted (sex, age, education) regression coefficients and prevalence ratios, using linear and Poisson regression, respectively, to quantify associations with cancer-specific knowledge. The proportions of nonresponse ranged from 13.4 to 63.5% for the most frequent cancer in Portugal and the leading cause of cancer, respectively. The mean of the estimated lifetime risk of cancer in the Portuguese population was 37.0%. A total of 47.5% of the respondents identified breast cancer as the most frequent in Portugal, 72.0% named lifestyles as the leading cause of cancer and 40.2% selected not smoking as the most important preventive behaviour. Lower levels of education were associated with higher proportions of nonresponse, but not consistently with inaccurate knowledge. Men provided lower estimates of the lifetime risk of cancer, indicated breast cancer less frequently and more often lung cancer as the most frequent, and were more likely to select not smoking as the most important preventive behaviour. The present study provides relevant data on knowledge of cancer prevention, which may be used for the planning and evaluation of awareness-raising and primary prevention interventions in Portugal.

    Ticks are important vector arthropods of human and animal pathogens. As information about agents of disease circulating in vectors in Portugal is limited, the aim of the present study was to detect bacteria and parasites with veterinary and zoonotic importance in ticks collected from dogs, cats, and field vegetation. A total of 925 ticks, comprising 888 (96.0%) adults, 8 (0.9%) nymphs, and 29 (3.1%) larvae, were collected in 4 geographic areas (districts) of Portugal. Among those, 620 (67.0%) were removed from naturally infested dogs, 42 (4.5%) from cats, and 263 (28.4%) were questing ticks obtained from field vegetation. Rhipicephalus sanguineus was the predominant tick species, and the only one collected from dogs and vegetation, while all Ixodes ricinus specimens (n=6) were recovered from cats. Rickettsia massiliae and Rickettsia conorii were identified in 35 ticks collected from cats and dogs and in 3 ticks collected from dogs. Among ticks collected from cats or dogs, 4 Rh. sanguineus specimens were detected with Hepatozoon felis, 3 with Anaplasma platys, 2 with Hepatozoon canis, one with Anaplasma phagocytophilum, one with Babesia vogeli, one with Borrelia burgdorferi sensu lato and one with Cercopithifilaria spp. Rickettsia helvetica was detected in one I. ricinus tick collected from a cat. To the best of our knowledge, this was the first time that Cercopithifilaria spp., Ba. vogeli, H. canis, and H. felis have been detected in ticks from Portugal. The wide range of tick-borne pathogens identified, some of zoonotic concern, suggests a risk for the emergence of tick-borne diseases in domestic animals and humans in Portugal. Further studies on these and other tick-borne agents should be performed to better understand their epidemiological and clinical importance, and to support the implementation of effective control measures.

  19. Estimation of the Crustal Bulk Properties Beneath Mainland Portugal from P-Wave Teleseismic Receiver Functions

    In this work, we present results from teleseismic P-wave receiver functions (PRFs) obtained in Portugal, Western Iberia. A dense seismic station deployment conducted between 2010 and 2012, in the scope of the WILAS project and covering the entire country, allowed the most spatially extensive probing on the bulk crustal seismic properties of Portugal up to date. The application of the H- κ stacking algorithm to the PRFs enabled us to estimate the crustal thickness ( H) and the average crustal ratio of the P- and S-waves velocities V p/ V s ( κ) for the region. Observations of Moho conversions indicate that this interface is relatively smooth with the crustal thickness ranging between 24 and 34 km, with an average of 30 km. The highest V p/ V s values are found on the Mesozoic-Cenozoic crust beneath the western and southern coastal domain of Portugal, whereas the lowest values correspond to Palaeozoic crust underlying the remaining part of the subject area. An average V p/ V s is found to be 1.72, ranging 1.63-1.86 across the study area, indicating a predominantly felsic composition. Overall, we systematically observe a decrease of V p/ V s with increasing crustal thickness. Taken as a whole, our results indicate a clear distinction between the geological zones of the Variscan Iberian Massif in Portugal, the overall shape of the anomalies conditioned by the shape of the Ibero-Armorican Arc, and associated Late Paleozoic suture zones, and the Meso-Cenozoic basin associated with Atlantic rifting stages. Thickened crust (30-34 km) across the studied region may be inherited from continental collision during the Paleozoic Variscan orogeny. An anomalous crustal thinning to around 28 km is observed beneath the central part of the Central Iberian Zone and the eastern part of South Portuguese Zone.
