    This paper deals with the mining of reworked gossan at Riotinto (Huelva, southwest Spain). The rock in question is a conglomerate formed by the erosion of gossan and its subsequent deposition in areas at some distance from its origin. In Roman times this mineral was used as construction material as well as for architectural decoration and possibly as an ore for making mining tools. This work focuses upon the exploitation of this mineral as an iron ore mined from the site known as Mesa Pinos or Alto de la Mesa by the Rio Tinto Company Ltd. between the last quarter of the 19th century and the first part of the 20th century.

    We analyse in this paper a bowl fragment, probably Milesian, which comes from the excavations of Calle del Puerto, in the Tartessian settlement of Huelva. Along the outside lip runs an archaic Ionian inscription —middle of the 6th c. B .C.— whose interpretation is particularly difficult. It may be a dedication or offering made by a Greek for a local chief. But nothing can be said about it with certainty. | Se estudia en este artículo un fragmento de cuenco, probablemente milesio, que procede ...

  3. The port of Huelva and the resurgence of mining (1873-1930); El Puerto de Huelva y el resurgir de la mineria (1873-1930)

    2011-07-01

    The setting up of the Committee of Works of the Port of Huelva coincided with the revitalization of mining in the province during the last third of the 19th century, stimulated by the injection of the foreign capital and technology. The mining legislation concerning customs duties of 1868 also contributed to triggering mining fever. For its part, the Port of Huelva began its administrative development within a succession of norms by which other similar bodies were progressively created along the Spanish coasts, with the encouragement of the local middle-classes. Mineral ores began to emerge from the bowels of the earth in Huelva at the eager hands of the miners, especially copper, manganese and pyrites, which was transported by the railways to the Port of Huelva, from whence, thanks to the development of its infrastructure, they were subsequently exported, mainly to a Europe in the throes of its second industrial revolution.

    Full Text Available Uno de los nichos laborales en los que más fácilmente encuentran empleo los inmigrantes extranjeros es en la prostitución, sobre todo las mujeres. Estas nuevas trabajadoras se incorporan a todas las variantes que tiene el oficio, desde los clubs de alterne a la calle. La urgencia por conseguir el dinero necesario con el que subsistir o pagar las deudas contraídas para su viaje al «paraíso», una posible explotación sexual por las mafias, la dificultad para acceder a otros puestos de trabajo y los substanciosos ingresos que en ocasiones pueden conseguir explican esta situación. En esta comunicación se muestran las características sociodemográficas que presentan las mujeres que se dedican a esta actividad en la provincia de Huelva. Además se hace una exposición de los recursos existentes en este territorio para atender sus necesidades. El trabajo es resultado de la investigación que llevé a cabo en la ONG Huelva Acoge dentro del proyecto EQUAL ARENA, el cual es cofinanciado por la Unión Europea y la Junta de Andalucía.

  6. Impact of a 1755-like tsunami in Huelva, Spain

    Directory of Open Access Journals (Sweden)

    Full Text Available Coastal areas are highly exposed to natural hazards associated with the sea. In all cases where there is historical evidence for devastating tsunamis, as is the case of the southern coasts of the Iberian Peninsula, there is a need for quantitative hazard tsunami assessment to support spatial planning. Also, local authorities must be able to act towards the population protection in a preemptive way, to inform "what to do" and "where to go" and in an alarm, to make people aware of the incoming danger. With this in mind, we investigated the inundation extent, run-up and water depths, of a 1755-like event on the region of Huelva, located on the Spanish southwestern coast, one of the regions that was affected in the past by several high energy events, as proved by historical documents and sedimentological data. Modelling was made with a slightly modified version of the COMCOT (Cornell Multi-grid Coupled Tsunami Model code. Sensitivity tests were performed for a single source in order to understand the relevance and influence of the source parameters in the inundation extent and the fundamental impact parameters. We show that a 1755-like event will have a dramatic impact in a large area close to Huelva inundating an area between 82 and 92 km2 and reaching maximum run-up around 5 m. In this sense our results show that small variations on the characteristics of the tsunami source are not too significant for the impact assessment. We show that the maximum flow depth and the maximum run-up increase with the average slip on the source, while the strike of the fault is not a critical factor as Huelva is significantly far away from the potential sources identified up to now. We also show that the maximum flow depth within the inundated area is very dependent on the tidal level, while maximum run-up is less affected, as a consequence of the complex morphology of the area.

    2016-06-01

    Relationship between toxicity and bioavailable metals in sediments from the Huelva estuary and its littoral of influence was analyzed. Toxicity was assessed with Microtox® bioassay using a marine luminescent bacterium: Vibrio fischeri. Bioavailable metals were considered as both, acid extractable fraction of BCR procedure and the sum of exchangeable and bound to carbonates fractions of Tessier sequential extraction. A bioavailable metals index was calculated to integrate results in a single figure. Toxicity and bioavailable metals showed a similar pattern. Higher levels were found in the estuary than in the littoral (140 TU/g). In Huelva estuary, highest levels were found in the Tinto estuary (5725 TU/g), followed by the Odiel estuary (5100 TU/g) and the Padre Santo Canal (2500 TU/g). Results in this area were well over than those in nearby estuaries. Furthermore, they are similar to or even higher than those in other polluted sediments around the world. Bioavailable metal index showed a stronger correlation with acid extractable fraction of BCR (R(2) = 0.704) than that for the sum of exchangeable and bound to carbonates fractions of Tessier (R(2) = 0.661). These results suggest that bioavailable metals are an important source of sediment toxicity in the Huelva estuary and its littoral of influence, an area with one of the highest mortality risks of Spain.

    2016-06-01

    Full Text Available In just two decades, the city of Huelva and its agro-industry belt has gone from being mainly farming spaces to become cities completely urbanized. Among other consequences, this population boom is due to the increase of the immigrant population, mostly from Europe’s East, North Africa and Latin America. Therefore, migration is a global phenomenon, but the current radical tendencies and the increase of racism threaten the peace of prosperous societies. The situation of young people regarding the migratory phenomenon notices their differences in the educational ambience across the factors that determine the social functioning. In this article appears empirical evidences of a quantitative research conducted in four centers of Obligatory Secondary Education with the aim of addressing the attitudes and the behaviors of the young people from Huelva regarding immigration. On these results is highlighted a marked pattern of otherness where half of the interrogated persons identifies East Europeans like «others». The same happens with the religion or the race, though in this case the vast majority refers to the Muslim religion or the black race, respectively. Nonetheless, the most relevant result appeared is that more than 40 % of the interrogated persons maintains the denial of the right of asylum or the reduction of other rights to the newcomers. So, despite being favorable to the immigration and having an intercultural point of view, the young people of Huelva, in certain contexts, suggest features or values that usually coincide with the rejection or even the racism.

  16. Trace element partitioning and soil particle characterisation around mining and smelting areas at Tharsis, Riotinto and Huelva, SW Spain

    Energy Technology Data Exchange (ETDEWEB)

    Trace elements may present an environmental hazard in the vicinity of mining and smelting activities. However, the factors controlling trace element distribution in soils around ancient and modern mining and smelting areas are not always clear. Tharsis, Riotinto and Huelva are located in the Iberian Pyrite Belt in SW Spain. Tharsis and Riotinto mines have been exploited since 2500 B.C., with intensive smelting taking place. Huelva, established in 1970 and using the Flash Furnace Outokumpu process, is currently one of the largest smelter in the world. Pyrite and chalcopyrite ore have been intensively smelted for Cu. However, unusually for smelters and mines of a similar size, the elevated trace element concentrations in soils were found to be restricted to the immediate vicinity of the mines and smelters, being found up to a maximum of 2 km from the mines and smelters at Tharsis, Riotinto and Huelva. Trace element partitioning (over 2/3 of trace elements found in the residual immobile fraction of soils at Tharsis) and soil particles examination by SEM-EDX showed that trace elements were not adsorbed onto soil particles, but were included within the matrix of large trace element-rich Fe silicate slag particles (i.e. 1 mm o at least 1 wt.% As, Cu and Zn, and 2 wt.% Pb). Slag particle large size (1 mm o) was found to control the geographically restricted trace element distribution in soils at Tharsis, Riotinto and Huelva, since large heavy particles could not have been transported long distances. Distribution and partitioning indicated that impacts to the environment as a result of mining and smelting should remain minimal in the region.

    The combined analysis of (222)Rn activity concentrations and mesoscale meteorological conditions at Huelva city (Spain) was addressed in this study to understand the potential impact of phosphogypsum piles on the (222)Rn activity concentrations registered at this area. Hourly mean data from April 2012 to February 2013 registered at two sampling sites (Huelva city and in the background station of El Arenosillo, located 27 km to the south-east) have been used in the study. The results of the present study showed a large difference in mean radon concentrations between the two stations during the sampling period, 6.3 ± 0.4 Bq m(-3) at Huelva and 3.0 ± 0.2 Bq m(-3) at El Arenosillo. The analysis has demonstrated that hourly (222)Rn concentrations at Huelva city above 22 Bq m(-3), with nocturnal peaks up to 50 Bq/m(3), mainly coincided with the occurrence of a pure sea-land breeze cycle. Mesoscale circulations in this region are mainly characterized by two patterns of sea-land breeze, pure and non-pure, with the phosphosypsum piles directly upstream (south) of the city during the afternoon on pure sea-breeze days. The difference between mean (222)Rn activity concentrations at Huelva city were 9.9 ± 1.5 Bq m(-3) for the pure pattern and 3.3 ± 0.5 Bq m(-3) for the non-pure pattern, while in the background station concentrations were 3.9 ± 0.4 Bq m(-3) and 2.8 ± 0.4 Bq m(-3) respectively. Considering these large differences, a detailed analysis of composites and case studies of representative sea-land breeze cycles of both types and their impact on (222)Rn activity concentration was performed. The results suggested that the presence of the phosphogypsum piles was necessary in order to justify the high (222)Rn activity concentrations observed at Huelva compared with the background station in the afternoons on pure sea breeze days (1.5-2.0 Bq m(-3)). On the other hand, large night time differences between the two sites on these days were

    Bernabé, J. M.; Carretero, M. I.; Galán, E.

    The mineralogy of atmospheric particles at the confluence of the Tinto and Odiel rivers, south of Huelva (a highly industrialized city in the SW Spain), was characterized in view to identify source origins. In spite of the small amount of sample collected, mineralogical characterization was performed by X-ray diffraction, polarized light microscopy and scanning electron microscopy with EDS analysis system, using an adequate sample preparation methodology. Sedimentable (SP) and aerosols particles were sampled an one-week basis every two months for one year. Quartz, calcite and feldspars were found to be the major minerals in both fractions, and phyllosilicates, dolomite and gypsum were also identified in lower content. Minor mineral particles included barite, apatite, sphalerite and pyrite. SEM studies revealed the additional presence of chalcopyrite in both SP and aerosols, and of chalcocite-covellite, halite and sylvite in the latter. Siderite, hematite and ankerite were only detected in the SP fraction. The concentrations of the previous minerals increased in summer by effect of the limited rain and the resulting scarcity of atmosphere washing. Non-mineral particles detected by SEM in SP and aerosol fractions included spherical, biological and compositionally complex particles. The main source of mineral particles was found to be the soil suspension in addition to the metallurgical and fertilizer production industries in the area.

    This is the first report of ostreid herpesvirus 1 microvariant (OsHV-1 µVar) infecting natural oyster beds located in Huelva (SW Spain). The virus was detected in 3 oyster species present in the intertidal zone: Crassostrea gigas (Thunberg, 1793), C. angulata (Lamarck, 1819) and, for the first time, in Ostrea stentina Payraudeau, 1826. Oysters were identified by a specific polymerase chain reaction (PCR) and posterior restriction fragment length polymorphism (RFLP) analysis based on cytochrome oxidase I (COI) mitochondrial DNA. Results confirmed that C. angulata still remains the dominant oyster population in SW Spain despite the introduction of C. gigas for cultivation in the late 1970s, and its subsequent naturalization. C. angulata shows a higher haplotype diversity than C. gigas. OsHV-1 virus was detected by PCR with C2/C6 pair primers. Posterior RFLP analyses with the restriction enzyme MfeI were done in order to reveal the OsHV-1 µVar. Detections were confirmed by DNA sequencing, and infections were evidenced by in situ hybridization in C. gigas, C. angulata and O. stentina samples. The prevalence was similar among the 3 oyster species but varied between sampling locations, being higher in areas with greater harvesting activities. OsHV-1 µVar accounted for 93% of all OsHV-1 detected.

    Huelva Estuary is a transition zone where REE-rich acidic waters interact with saline-alkaline seawater. This mixing process influences the geochemical and mineralogical characteristics of particulate and dissolved fractions. The Tinto River has >11,000μgL -1 dissolved REE (pH=1.66), whereas seawater only reaches 8.75·10 -2 μgL -1 dissolved REE (pH=7.87). REE-normalized patterns in "pH<6 solutions" are parallel and show similarities, diminishing their concentration as pH increases. Sequential extraction performed on the generated precipitates of mixed solutions indicates that most REE are associated to the residual phase. In a second order, REE are associated with soluble salts at pH3 and 3.5 whereas in sediments generated at pH4 and 5, they are distributed in salts (1° extraction), poorly crystallized Fe-bearing minerals (schwertmannite, 3° extraction) and well crystallized Fe-bearing minerals (goethite - hematite, 4° extraction). Finally, precipitated REE are highest at pH6 newly formed minerals with a release to solution in higher pH. Copyright © 2017 Elsevier Ltd. All rights reserved.

    The soil vulnerability determines the sensitivity of the soil after an accidental radioactive contamination due to Cs-137 and Sr-90. The Departamento de Impacto Ambiental de la Energia of CIEMAT is carrying out an assessment of the radiological vulnerability of the different Spanish soils found on the Iberian Peninsula. This requires the knowledge of the soil properties for the various types of existing soils. In order to achieve this aim, a bibliographical compilation of soil profiles has been made to characterize the different soil types and create a database of their properties. Depending on the year of publication and the type of documentary source, the information compiled from the available bibliography is very heterogeneous. Therefore, an important effort has been made to normalize and process the information prior to its incorporation to the database. This volume presents the criteria applied to normalize and process the data as well as the soil properties of the various soil types belonging to the provinces of Jaen, Cordoba, Sevilla and Huelva of the Comunidad Autonoma de Andalucia.

    Full Text Available The article expounds the experience of the restoration of the Walled Area of Niebla (Huelva for the Ministry of Culture. It is an Almohade fortification made of adobe walls of red earth and stone of the area, which was in a lamentable state of abandonment. The singularity of the intervention lies in the methods used for the project and the originality of the material to be restored, which because of its heterogeneousness, made obligatory the making of a new face between 25 and 150 cm of adobe walls of stabilized earth which was sewn to the old ones. The article is introduced through a series of considerations on earth architecture, and after a historical review of Niebla, describes the structure and documents of the project and also gives a description of the works carried out, explaining the details of the material (dosification: 3 parts of red earth, 2 of sand, 3 of minute gravel, 2 of calcium and 1 of cement; plasticity by organoleptical procedures, and the auxiliary means employed (boards of 90 cm to one face, waters not extracted, sewn bv mortisina and metallic legs.

The main aim of our approach is to reconcile the diffusion of the results obtained after the excavation, documentation, and the study of the archaeological record with the methodological analysis of a Geographic Information System (GIS. We consider that a GIS is the most appropriate tool in archaeology for this purpose since it allows users to manage a large amount of data in diverse formats and insert it in a closed topographic reference frame. For that purpose, we restrict the field of action to the North House (a house built in the time of Emperor Augustus that lasted until the 3rd century AD. The real power of this research relies on the integration of the digital building archaeological record in a GIS, while the architecture of the Roman house is reconstructed virtually from archaeological remains, in this way the domestic space is visually comprehensible. According to the results obtained in this pilot experience, we can affirm that the union of GIS and infographics allows archaeological reality to surpass the strictly academic scope and promote it to society making possible the Arucci site approachable to professionals of archaeology as well as to the uninitiated. The feasibility of the proposal that was carried out within the North House encourages us to consider the export of this study model to the rest of buildings that make up the site such as the foro, macellum, balneum as, well as other domus.

    Photochemical ozone pollution of the lower troposphere (LT) is a very complex process involving meteorological, topographic emissions and chemical parameters. Ozone is considered the most important air pollutant in rural, suburban and industrial areas of many sites in the world since it strongly affects human health, vegetation and forest ecosystems, and its increase during the last decades has been significant. In addition, ozone is a greenhouse gas that contributes to climate change. For these reasons, it is necessary to carry out investigations that determine the behaviour of ozone at different locations. The aim of this work is to understand the levels and temporal variations of surface ozone in an industrial-urban region of the Southwest Iberian Peninsula. The study is based on ozone hourly data recorded during a 6-year period, 2000 to 2005 at four stations and meteorological data from a coastal station. The stations used were El Arenosillo and Cartaya--both coastal stations, Huelva--an urban site and Valverde--an inland station 50 km away from the coastline. The general characteristics of the ozone series, seasonal and daily ozone cycles as well as number of exceedances of the threshold established in the European Ozone Directive have been calculated and analysed. Analysis of the meteorological data shows that winter-autumn seasons are governed by the movement of synoptic weather systems; however, in the spring-summer seasons, both synoptic and mesoescale conditions exist. Average hourly ozone concentrations range from 78.5 +/- 0.1 microg m(-3) at Valverde to 57.8 +/- 0.2 microg m(-3) at Huelva. Ozone concentrations present a seasonal variability with higher values in summer months, while in wintertime, lower values are recorded. A seasonal daily evolution has also been found with minimum levels around 08:00 UTC, which occurs approximately 1-1.5 h after sunrise, whereas the maximum is reached at about 16:00 UTC. Furthermore, during summer, the maximum value

    The correct diagnosis of hypothyroidism during pregnancy requires knowledge of the local trimester-specific thyrotropin (TSH) reference ranges. When these are not available, the guidelines recommend upper limits of 2.5, 3.0, and 3.0μU/ml for the 1 st , 2 nd , and 3 rd trimesters, respectively. The aim is to establish the reference range for our local population. A population-based observational study was performed on healthy pregnant women from 11 healthcare centres in the province of Huelva. Women were recruited consecutively during 2016 through the pregnancy process. Women were excluded who had a history of thyroid or medical disease, a poor obstetric history, multiple pregnancy, thyroid autoimmunity, and extreme TSH values (10μU/ml), as well as women treated with levothyroxine for thyroid dysfunction. The study included a total of 186 pregnant women, with a mean age of 30.7 years (95% CI: 29.8-31.6) and a body mass index (BMI) of 23.6 (95% CI: 23.2-24.0). Most of them had the first laboratory tests performed before week 11 of pregnancy. Valid subjects for analysis were 145, 105, and 67 pregnant women in the 1 st , 2 nd , and 3 rd trimesters, respectively, after excluding those due to abortion (18.9%), autoimmunity (6.5%), hypo/hyperthyroidism (2.2%), and levothyroxine treatment during the 2 nd /3 rd trimester (18.6%). The 97.5% TSH percentile for the 1 st , 2 nd , and 3 rd trimester was 4.68, 4.83, and 4.57μU/ml, respectively. Thyroid dysfunction was identified in 80 women (55.2%), 33 of whom received treatment with Levothyroxine (22.7%). With the new criteria, thyroid dysfunction prevalence would be reduced to 6.2%, and the need for treatment to 4.1%. The reference range for TSH in our population differs from that proposed by the guidelines. Unnecessary treatment was being given to 18.6% of pregnant women.

    Major ions, nutrients, trace elements and pesticides distribution were studied in a coastal wetland heavily impacted by human development in Spain. Past land use has altered the local hydrodynamics leading to the partitioning of the ecosystem into a tideland subject to marine influence, and an artificial freshwater reservoir created by stream impoundment. The tideland stretch is flooded twice a day with a heavy metal plume that emerges from the mine-polluted estuary of Huelva and propagates landward depicting the same dispersal trend of major seawater ions. Additionally, the tidal channel receives acid discharges from industrial point sources that contribute to metal enhancement. The impounded area and stream tributaries are affected by agrochemicals runoff (nitrate, phosphate, pendimethalin, simazine, diuron and therbuthylazine) from surrounding agricultural lands. The tidal regime plays a crucial role in the transport and dispersion of pollutants, except in the artificial reservoir where freshwater exhibits a seasonal mineralization pattern.

    Women seem more willing to donate blood than men despite the limitations that affect their donation rate. The aim of our study was to determine the role of women in altruistic donation of blood in Huelva, a province in south-western Spain. We registered 87,601 offers to donate whole blood between January 1st, 2005 and December 31st, 2009. We statistically analysed variables such as sex, age, offers, deferrals and donations, problems in venous access, vasovagal reactions, weight and blood pressure to establish their significance according to donor gender. With regards to gender, 52.3% of donors were women and 47.7% men. Of the 87,601 offers to donate blood, 46.5% were from females and 53.5% from males. More females than males made their first donation during the study period. However, 43.9 % of donations were from women, whereas 56.1% were from men. Overall 8.7% of offers were deferred, 62.7% of which due to a low haemoglobin concentration, which was the most frequent cause of deferral in women. Difficulties in venous access and vasovagal reactions were also more frequent in female donors than in male donors. By the end of the study period, donor fidelity was 58.6% for men and 48.6% for women. In the province of Huelva, women are more altruistically inclined than men to give blood, with the percentages of donors and first-time donors being higher among females. However, there are restrictions to women giving blood, especially low haemoglobin concentration, which reduce the number of female blood donations. Women also have more difficulty when blood is withdrawn and are more susceptible to vasovagal reactions, which negatively affect their experience as donors. Measures should be taken to reduce these barriers to encourage women to continue to offer to donate blood, thereby ensuring that they become regular donors, which is a key factor in guaranteeing an adequate supply of blood within the region of Andalusia.

    The soil vulnerability determines the sensitivity of the soil after an accidental radioactive contamination due to Cs-137 and Sr-90. The Department de Impacto Ambiental de la Energia of CIEMAT is carrying out an assessment of the radiological vulnerability of the different Spanish soils found on the Iberian Peninsula. This requires the knowledge of the soil properties for the various types of existing soils. In order to achieve this aim, a bibliographical compilation of soil profiles has been made to characterize the different soil types and create a database of their properties. Depending on the year of publication and the type of documentary source, the information compiled from the available bibliography is very heterogeneous. Therefore, an important effort has been made to normalize and process the information prior to its incorporation to the database. This volume presents the criteria applied to normalize and process the data as well as the soil properties of the various soil types belonging to the provinces of Jaen, Cordoba, Sevilla and Huelva of the Comunidad Autonoma de Andalucia.

    Metallurgic mine wastes often contain high concentrations of potentially toxic elements, the mobility of which may pose an environmental hazard for water and surrounding ecosystems. We have examined the mobility of Ag, As, Cu, Pb and Zn from composite surface samples (0-20 cm) of different pyritic tailings impoundments in the province of Huelva (Spain). These samples were also subject to physical chemical and mineralogical (XRD) characterization. The total metal content of the tailings ranged between 1.89-11.2 ppm for Ag, 72-610 ppm for As, 245-1194 ppm for Cu, 220-11933 for Pb and 41-706 for Zn, all proving to be highly acidic. The mobility of these elements was assessed by using a seven-step sequential extraction procedure and applying the toxicity characteristic leaching procedure (TCLP). We investigated the applicability of TCLP to the tailings by comparing the results with those of the first steps of the sequential extraction procedure. It was found that the pH values remained buffered (close to 4.97) upon adding the TCLP extraction reagent and that the pH values differed significantly from those of the aqueous extracts. This could result in an underestimation of mobile forms compared with those dissolved in water. We may also conclude that due to the presence of specific minerals or to the preference of some elements for acetate ions the results of any assessment of metal mobility in pyritic tailings using the TCLP test may be questionable.

Examinaremos este caso a través de una perspectiva de green criminology, identificando las cuestiones teóricas y los enfoques metodológicos que pueden adoptarse cuando se estudia un caso de crimen medioambiental todavía vigente como el que se presenta aquí. Nuestra investigación se desarrollará partiendo de preguntas como: ¿Qué opinan y cómo se sienten los habitantes de la zona afectada cuando describen el problema de la contaminación y de las consecuencias empíricas de este crimen medioambiental? ¿Cuáles son las cuestiones decisivas que, más allá de los límites de las definiciones legales de crimen, y de las aproximaciones criminologícas tradicionales, plantean tales narraciones? En el transcurso de la investigación, tendremos que observar, examinar y analizar las interacciones entre los seres humanos y el medio ambiente en el que habitan, más aún en los casos en los que estas interacciones se nos revelen insatisfactorias, frustrantes y llenas de riesgos catastróficos. También desde esta perspectiva, un posible enfoque del daño social implica una transformación de las relaciones sociales y medioambientales destructivas.

    Document available in extended abstract form only. On 1998 a 137 Cs source was accidentally molten in the installations of a Spanish company of stainless steel production. Not being aware of the contamination with Cs, the produced powder was treated in an inert plant and these inert materials were normally used as filling material to restore phosphogypsum piles. The contaminated material ended up in the phosphogypsum piles at the Center of Inert Recuperation (CRI), located at the salt marshes of Huelva (Spain). This is a large extension oriented towards the sea with marsh vegetation subject to the tide. Since the cesium contamination was discovered, this zone has been thoroughly analyzed in order to evaluate the radiological impact of the presence of cesium and the possible contamination of soils and water in the surrounding. Recently, in two different locations at CRI, permeable reactive barriers were constructed to retard cesium migration. The main component of these barriers is a clay material called Rojo Carbonero (RC), whose properties as cesium sorbent have to be analyzed in depth. This material is mainly formed by: quartz (27%), phyllosilicates (58%), dolomite (8%), feldspar (2%), hematite (5%). The clayey fraction (<2 μm) is composed by a 98% of illite and the rest is chlorite/kaolinite. Different studies were carried out to quantify the sorption of cesium in this material previous to the construction of the reactive barriers. Due to the large variability of the chemical composition of the waters at the site a significant variability of sorption values, in terms of distribution coefficients (Kd) was also observed. In order to predict the migration of cesium in these barriers, taking into account this variability and the presence of competing ions, a detailed experimental study was carried out with the aim of determining the selectivity coefficients of cesium with respect to the main ions present in the water. Basically, the material was converted in

    Full Text Available Este artículo surge como resultado de una Tesis de Maestría desarrollada en la Ciudad de Huelva (España, sobre procesos de integración social de inmigrantes en el entorno escolar. El objetivo consiste en analizar los procesos de integración de niños inmigrantes en las escuelas de Huelva, reconociendo el rol social que cumple la escuela con respecto a su formación y sus oportunidades de socialización. En cuanto a la metodología, se recurre al análisis del discurso a partir de datos obtenidos en entrevistas en profundidad y talleres de interculturalidad donde participaron estudiantes, docentes y padres de familia. Como principal resultado del análisis, se plantea que el reto de la escuela no consiste en adaptar los contenidos curriculares a la diversidad existente en su entorno, sino que los debe gestionar efectivamente, atendiendo a las necesidades particulares de los inmigrantes.Pues allí, se ejercen derechos y deberes ciudadanos así como oportunidades de participación social. De esta manera, se concluye que el reto de la escuela en contextos interculturales consiste en fomentar la integración social a través del desarrollo de habilidades para la vida y la socialización. Para ello, debe reorientar la trayectoria vital de niños que han dejado sus raíces, promoviendo un diálogo entre su pasado y su presente, permitiéndoles desarrollar estrategias concretas en favor de la construcción de su proyecto de vida en un nuevo contexto social.

    Full Text Available The estuary of Ría of Huelva, recognized like Reserve of the Biosphere by UNESCO, is affected by spills of diverse origin. The method Sistémico Multivariado (MSM, applied prior to harbor works or in economy, has been used to characterize the estuary in risk terms and environmental reliability. After determining the variables that take part and to describe the mechanisms of performance of toxics, these have been classified in cancerigenic and noncancerigenic. Criteria defined by Environmental Protection Agency have been used (EPA-EEUU, the “dose of reference” for the noncancerigenic ones, the “factor of fall” for the cancerigenic ones, paying attention to the “components of failure”. The reliability of the system has been analyzed and the one of each component, with which it must have the system “Ría of Huelva”, following methodology MSM on determination of the permissible reliability of a design system. The reliability of the system is despicable for the physiological conditions of the studied fish, meaning that determined species are condemned to their extinction or its absence of the place. One has seen the applicability of the MSM the characterization of the environmental state of certain environmental factors and ecosystems. Also it has been possible to state the precarious situation of the piscicolas species in Ría of Huelva and the importance of the synergic effect, in the model proposed, on the conditions that undergo the affected populations, in front of the model additive used habitually by the EPA.

    Full Text Available Until recently, talk about tourism in the province of Huelva was to do exclusively with the coastal areas. Even today, and for a long time, these areas will continue hoarding the bulk of demand and equipment, based on the binomial “sun and sand”. However, in recent years the interior spaces are approaching the new demand for tourism, offering a rural landscape, an environment and a different cultural and historical heritage to you coastal tourist areas. A little beyond this issue, industrial and mining areas, sunk into crisis ore production system, today found a new path for development in the value enhancement of industrial mining heritage. One such area is the Andévalo Western mining, where mining has been one of the pillars upon which traditionally has built its economy, which has marked its evolution through the centuries. The development of the municipalities located in this region has been based essentially on short-term exploitation of natural resources, almost exclusively from metal mining.

    The response of wild fish to heavy metals was studied in sole (Solea senegalensis) collected in 2004, 2005 and 2006 at three sampling sites from Huelva estuary (SW Spain), in the vicinity of a petrochemical and mining industry. Heavy metals As, Cd, Cu, Fe, Pb and Zn were analyzed in samples collected from sediment, water and tissue (liver) to examine their bioconcentration and effects in fish such as lipid peroxidation (LPO), catalase (CAT; EC 1.11.1.6), glutathione peroxidase (GPx; EC 1.8.1.7), glutathione S-transferase (GST; EC 2.5.1.18) and glutathione reductase (GR; EC 1.11.1.6) were also analyzed in the fish liver. The results showed different effects in sole from diverse locations with varying degrees of pollution. Significant differences in LPO, CAT and GR activities between control fish and fish from sampling sites were observed as well as seasonal differences for biomarkers. Significant correlations were established between some biomarkers and heavy metals concentrations in liver, sediment and water. This study indicates the usefulness of integrating a set of biomarkers to assess the effects of pollutants in aquatic environments under complex mix of pollutants and chronic pollution situation.

    Full Text Available La nueva política del gobierno español de contrataciones de trabajadores migrantes temporales ha instaurado en la provincia de Huelva una nueva etapa en el proceso de sustitución de trabajadores agrícolas. Primero, la salida de trabajadores temporales españoles propició la llegada de trabajadores extranjeros, principalmente marroquíes. Ahora, estos trabajadores provenientes de la región del Magreb en el noroeste de África están siendo desplazados por trabajadoras de la Europa del Este, principalmente de Polonia, Rumania y Bulgaria. En este artículo se analizan los procesos de exclusión laboral de los magrebíes y la inserción y movilidad de las trabajadoras de Europa del Este, grupos que están siendo sujetos a un intenso proceso de estigmatización por parte de la sociedad local. Esto ha provocado el surgimiento de conflictos inter étnicos derivados de la competencia en el mercado de trabajo.

OBJETIVO: conocer las actitudes, intereses, creencias, expectativas y vivencias de la comunidad educativa de la Escuela de Enfermería de la Universidad de Huelva respecto al desarrollo de los créditos de Libre Configuración. SUJETO Y MÉTODO: se realizaron entrevistas semiestructuradas y grupos de discusión a los sectores del alumnado, profesorado y cargos directivos. RESULTADOS PRINCIPALES: El análisis de los diferentes discursos sociales pone de manifiesto que el desarrollo de los créditos de Libre Configuración en el diseño curricular de Enfermería no cumple su misión formativa global, detectándose, por tanto, una fuerte contradicción entre la filosofía de la Libre Configuración y lo que realmente se lleva a la práctica. Los actores participantes en este proceso formativo lo viven como una carga curricular adicional con escaso valor educativo. CONCLUSIONES: La Libre Configuración no alcanza el objetivo de formación global que se pretendió al ser introducida en el currículo de Enfermería.

    Full Text Available Rural tourism businesses have experienced a very remarkable growth in recent times, providing regions with large opportunities to develop economically and socially. Part of the success of these businesses is due to the search of quality in the services they provide. In this work the influence of various dimensions of total quality orientation on staff satisfaction, communication and commitment in this tourist sector are analysed. The sample was made up of staff from hotels and restaurants in the mountainous area of “Sierra de Aracena y Picos de Aroche” in the province of Huelva, using Gómez-Bernabeu’s Quality and Culture Questionnaire for data collection. By means of linear regressions it was observed that the dimensions of acknowledgement and continuous improvement have an influence on communication, while development and training of human resources would be the best predictor of job satisfaction. Nevertheless, no conclusive data were obtained regarding organizational commitment.

    Full Text Available La práctica de actividad física es uno de los hábitos saludables más recomendados por numerosos expertos. Por otra parte, el comienzo de los estudios universitarios coincide, en muchos casos, con el inicio del sedentarismo. En este estudio pretendemos conocer y analizar los hábitos de práctica deportiva y relacionarlos con los estilos de vida del alumnado de la Universidad de Huelva. Para obtener datos de esta población de estudio hemos diseñado un cuestionario que recoge aspectos como: datos identificativos, gestión deportiva universitaria, práctica de actividad física, aspectos psicosociales de la práctica de actividad físico-deportiva, influencia de la educación física escolar, tiempo libre, y hábitos saludables. Para el diseño de este instrumento hemos utilizado una técnica de consulta a expertos denominada método Delphi. Antes de administrarlo en toda la Universidad, con objeto de asegurar su validez, realizamos un estudio piloto en la Facultad de Ciencias de la Educación. Una vez corregido se aplicó a la muestra representativa de los universitarios. Posteriormente, con en fin de profundizar sobre estos datos, se diseñaron y aplicaron unas entrevistas en forma de historias de vida a cuatro alumnas con diferentes perfiles, para ampliar información acerca de sus hábitos de práctica de actividad física. Seguidamente se compararon los datos obtenidos con ambos instrumentos. Entre los resultados obtenidos del cuestionario podemos destacar que, el 41,9% del alumnado practica actividad física, aunque con una frecuencia de al menos tres días a la semana se reduce al 23,7%, siendo los hombres más activos que las mujeres.

Después de un siglo de existencia, tenemos mucha documentación sobre psicomotricidad, sus metodologías, sus contenidos, sus ámbitos de intervención y evaluación, pero poco sabemos sobre opiniones de los profesores, sobre la formación que dicen poseer estos enseñantes, que son los encargados de llevar a cabo proyectos psicomotores en los centros educativos. Es por ello que hemos sentido la necesidad de recoger información sobre la formación que dicen poseer los maestros de Educación Infantil y de Educación Especial de la provincia de Huelva. Entre las conclusiones principales podemos destacar que el 66,7% de nuestros profesores se considera capacitado para esta tarea. De igual forma, el 73,1% de los encuestados piensa que: el apoyo técnico recibido de la administración es nulo o poco. Por otro lado, a pesar de que el 60,7% de los maestros señala que participa en actividades de perfeccionamiento, resulta sorpresivo que el 78,1% no pertenece a grupos de trabajo, seminarios, etc. Además, el 68,3% de ellos expresa que lee ninguno o pocos artículos relacionados con el tema objeto de investigación.

We will try to find out its importance in the university scope through students’ opinions and the analysis of the didactic program of Early Childhood Education Degree.In order to achieve this, we have set ourselves the general objective of gathering information from university students of the Early Education Degree about the importance of training in prenatal education for their future work as teachers, considering that they are the most involved in the education of children in their early stages. Furthermore, we intend to reckon the relevance given to this content by the University of Huelva, one of the educational institutions responsible for teacher training.The data were collected through questionnaires applied to a sample of 58 3rd-4th level students of Early Childhood Education at the University of Huelva. This instrument was selected for the suitability of its application collectively. Moreover, an analysis of the didactic programs of the courses of this degree was carried out to verify the existence of contents of prenatal pedagogy within them.From this research it is derived that certain notions of prenatal pedagogy are essential to become future nursery teachers, thus providing a greater amount of resources when facing our students’ learning process.In conclusion, we checked that the university students surveyed believe that it is necessary to have notions of prenatal pedagogy so as to become efficient teachers. The lack of this notion in the didactic programs represents a formative gap that will have negative repercussions on their initial formation and, consequently, on their educational practice. Therefore, the educational institutions in charge of the preparation of new teachers should consider including prenatal pedagogy within their didactic programs.

    The study of the evolutions of different wine pigment families, copigmentation/polymerisation processes and colour characteristics during the first year of ageing in oak barrel has allowed the assessment of the ageing aptitude of Syrah wines from "Condado de Huelva D.O.", a warm climate region. A total of 32 anthocyanic pigments were identified, including 14 major compounds from grape and 18 minor derivatives formed during the vinification. The anthocyanin profile changed towards more chemical complexity, being vitisin-like pyranoanthocyanins the predominant minor pigments during the first month of ageing. As wine became older, a progressive increase on the content of 4-vinylcatechin, 4-vinylphenol and 4-vinylcatechol compounds took place. Results showed that copigmentation occurred during the whole process of ageing inducing visual perceptible colour effects. Simultaneously to the copigmentation decrease, the degree of polymerisation increased during ageing, being maximum at 9 months old wines (77%). The colour of wines evolved progressively in a positive way from 3 to 9 months of ageing, becoming darker and with more vivid colour. However, from 9 to 12 months of ageing, the chemical structure of wines was negatively affected resulting in lighter, with more red-orange hues and less vivid colours. The inclusion of the chemical and colorimetric information on the PCA model allows us to reach very good discriminations among the Syrah wines with different wood contact period.

    Full Text Available La situación por la que atraviesa la economía internacional, las altas tasas de desempleo, el creciente número de cierres de empresas, la despoblación de algunas zonas y la masificación de otras, son las claves que caracterizan el mercado de trabajo español, en particular y la sociedad, en general. A principios de los años ochenta, empieza a oirse en ámbitos científicos, la idea de una descentralización a ultranza; sobre todo teniendo en cuenta, y hablando del entorno que nos ocupa, que en España se entra en el período democrático y por tanto, en "la era de las autonomías". Esta descentralización de la España democrática se caracteriza por la fuerte intervención del Estado en el desarrollo de las re­giones. Partían del Estado central las primeras iniciativas, con el fin primordial de borrar las desigualdades regionales, y más concretamente, el crecimiento de las áreas rurales retrasadas en contraposición a las zonas urbanas. La ineficacia derivada de esta etapa estuvo provocada, directa o indirectamen­te, por el reducido conocimiento de la Administración central de los numerosos recursos por explotar en nuestras comunidad es locales, que facilitarían el crecimiento económico y elevarían el nivel de vida, objetivos básicos en el fortalecimiento de nuestras economías endógenas. Esto nos induce a centrarnos en el estudio de la Teoría del Desarrollo Local como instrumento formulador de políticas convergentes hacia el desarrollo global y macroeconómico que gozan de autonomía para los intereses concretos de cada área. Por tanto, el principal objetivo en este trabajo de investigación ha sido iniciar un estudio más profundo de un tema tan actual, por su mucha utilización en la década en que vivimos y su reducido análisis por parte de los economistas, como puede ser la planificación estratégica y su implantación en un territorio concreto. El punto de partida implica necesariament e atender al concepto de desarrollo local y a toda la simbología que lo sustenta. Para ello hemos intentado realizar un breve barrido teórico donde definir el ámbito y la planificación asociada a la Estrategia de Desarrollo Local. En particular, en esta investigación, nos hemos centrado en el análisis multidimensional de la realidad socio-cultural y la estructura económica del mu­cipio de Lepe, con fuertes fundamentos económicos (la puesta en marcha del Plan de Regadíos del Chanza, foco turístico por excelencia y máximo exportador de fresas a la Comunidad Europea, pero con una alta tasa de analfabetismo que en un principio nos hace pensar, que puede reducir la utilización de instrumentos legales y financieros que optimizarían sus inversiones. Este estudio servirá de base para adentrarnos en esa primera fase de diagnóstico (que comentábamos con anterioridad, e iniciar con éste el Plan Estratégico de la Comarca de la Costa Occidental onubense que realizaremos en próximos estudios.

  18. Hydrodynamic characteristics of the western Doñana Region (area of El Abalario), Huelva, Spain

    Science.gov (United States)

    Trick, Thomas; Custodio, Emilio

    The Doñana region, in southwestern Spain, comprises a large and important nature reserve, the wetlands of which are affected by human activity. Planting of an extensive eucalyptus forest in the 1950s and, more recently, the use of aquifers for irrigation and water supply for some coastal tourist resorts, have altered the natural groundwater-flow system. The area of the study is the western sector of the region, called El Abalario, which is a gentle topographic elevation between the Atlantic coast and La Rocina Creek (Arroyo de la Rocina). Underneath a variable layer of eolian sands with high dunes near the coast, thick Plio-Quaternary detritic strata, mostly fine silica sands, overlie marls. Near the base there is a variable, deltaic-origin layer of coarse sands and gravels. The dome-shaped water table, inside the sands, is close to the surface everywhere except beneath the dune belt, and small, temporary, shallow lagoons are numerous. The coarse sand and gravel layer conditions groundwater flow and behaves as a semiconfined layer between sands. A cross section through the area was simulated with a model to check the validity of the conceptual groundwater-flow pattern and its sensitivity to the hydraulic parameters. The model was calibrated using parameter values obtained by pumping tests and multilevel piezometric data, and checked against the estimated groundwater discharge into La Rocina Creek. Groundwater flows peripherally to the sea coast, to La Rocina Creek, or directly east and southeastward into the Doñana marshlands, in the Guadalquivir River delta. The average net aquifer recharge rate was calculated to be between 100 and 200 mm year-1 for the area covered by brush, but is remarkably lower in the areas of eucalyptus trees. The transient-state model shows that recharge varies spatially and is not clearly proportional to annual precipitation. Phreatic evapotranspiration plays an important role in decreasing the net value of aquifer recharge to approximately 0.4-0.6 of that calculated with a soil-balance model. The cross section model was used to study the effect of groundwater ion on water-table depth by subtracting the contribution of vertical flow, calculated by a well-hydraulics formula, to the semiconfined deep aquifer. The result was a decrease in phreatic evapotranspiration, flow into La Rocina Creek, and lagoon-inundation frequency. Replacement of the eucalyptus forest with native vegetation may raise water-table levels and even reactivate old tributaries to La Rocina Creek. La région de Doñana, située dans le sud ouest de l'Espagne, comprend une importante réserve naturelle avec des zones humides, affectée par l'activité humaine. L'exploitation de vastes plantations d'eucalyptus pendant les années 50 et l'usage plus récent des nappes souterraines pour l'irrigation et l'alimentation en eau des centres touristiques côtiers ont modifié le système de flux d'eau souterraine dans cette zone. La présente étude a été réalisée dans le secteur occidental, appelé El Abalario. Ce secteur consiste en une légère élévation située entre l'Océan Atlantique et la ravine de La Rocina. Une couverture variable de sables éoliens, formant une haute crête dunaire côtière, recouvre des sédiments detritiques plio-quaternaires, déposés eux même sur des sables siliceux lesquels reposent à leur tour sur des marnes. Près de la base se trouvent des sables grossiers et des graviers d'origine deltaïque, dont l'épaisseur varie spatialement. Le flux d'eau souterraine est conditionné par l'aquifère semi confinés des graviers et des sables grossiers. Le niveau phréatique de l'aquifère libre des sables fluvio-marins est peu profond, excepté sous les dunes. On y trouve souvent des petites lagunes temporaires peu profondes. Le flux de l'eau souterraine a été simulé dans une section verticale pour vérifier le modèle hydrogéologique conceptuel et la sensibilité aux variations des paramètres. Le modèle a été calé en utilisant d'une part les valeurs des paramètres hydrauliques obtenus par des essais de pompage et d'après les données piezométriques mesurées à différentes profondeurs, et d'autre part l'apport estimé de la ravine de La Rocina. L'écoulement d'eau souterraine s'effectue par drainage latérale dans trois directions, d'une part vers la côte, d'autre part à travers la ravine de La Rocina et finalement directement vers les Marais de Doñana situés à l'est et sud-est dans le delta du fleuve Guadalquivir. Avec une pluviométrie moyenne comprise entre 550 et 600 mm, la recharge nette moyenne annuelle des nappes, pour des périodes de temps assez longues, est estimée entre 100 et 200 mm dans les aires de végétation autochtone, et elle est nettement inférieure dans les aires plantées deucalyptus. Le modèle transitoire montre que la recharge varie dans l'espace et qu'elle n'est pas clairement proportionnelle aux précipitations annuelles. L'évapotranspiration phréatique joue un rôle important et diminue la valeur nette de la recharge des nappes de 0,4 à 0,6 de la valeur calculée avec un modèle de bilan d'eau dans le sol. La section modélisée est utilisée pour étudier l'effet de l'extraction d'eau souterraine sur la profondeur du niveau phréatique en soustrayant le flux vertical, calculé grâce à une formule d'hydraulique des puits, de la nappe profonde semi-confinée. Le résultat de cette extraction est une diminution de l'évapotranspiration phréatique, du flux au niveau de la ravine de La Rocina et de la fréquence d'inondation des lagunes. La substitution de forêts d'eucalyptus par de la végétation autochtone peut permettre la remonté des niveaux phréatiques et même réactiver d'anciens ravins affluents à La Rocina. La región de Doñana, situada en el sudoeste de España, incluye una gran e importante reserva natural, cuyos humedales están siendo afectados por la actividad humana. La extensa plantación de eucaliptus en la década de 1950 y el uso más reciente de los acuíferos para riego y para abastecimiento de centros turísticos costeros han modificado el sistema de flujo del agua subterránea en esta zona. Este estudio se ha realizado en el sector occidental, llamado El Abalario. Se trata de una elevación suave situada entre el océano Atlántico y el arroyo de La Rocina. Debajo de un manto variable de arenas eólicas, que forma un alto cordón dunar costero, se encuentran sedimentos detríticos plio-cuaternarios formados por arenas silíceas finas, que hacia la base incluyen una capa de arenas gruesas y gravas de origen deltrico, los que a su vez yacen sobre margas. El flujo de agua subterránea está relacionado con niveles de gravas y gravillas semiconfinadas por las arenas fluvio-marinas que contienen el nivel freático. El nivel freático es somero excepto debajo del cordón dunar. Son frecuentes pequeñas lagunas temporales. Se ha simulado el flujo de agua subterránea en una sección para comprobar el modelo de flujo conceptual y la sensibilidad a variaciones de los parámetros. El modelo fue calibrado usando los valores de los parámetros hidráulicos obtenidos en ensayos de bombeo y datos piezométricos medidos a diferentes profundidades, y la descarga estimada al arroyo de La Rocina. La recarga de agua subterránea drena lateralmente, por un lado hacia la costa y por otro lado a través del arroyo de La Rocina, o directamente hacia las Marismas de Doñana situadas en el delta del río Guadalquivir. Con una lluvia media anual entre 550 y 600 mm, la recarga neta media estacionaria anual del acuífero, considerando periodos de tiempo largos, se estima entre 100 y 200 mm en las zonas de vegetación autóctona, y es notablemente menor en las zonas de plantación de eucaliptos. El modelo transitorio indica que la recarga varia espacialmente y no es claramente proporcional a la precipitación para periodos de un año. La evapotranspiración freática varia espacialmente y juega un papel importante; disminuye el valor neto de la recarga al acuífero para dejarlo en 0,4 a 0,6 de lo que se calcula mediante un balance de agua en el suelo. La sección modelada sirve para estudiar el efecto de la extracción de agua subterránea sobre la profundidad del nivel freático mediante la substracción del flujo vertical, que se calcula mediante una fórmula de hidráulica de pozos para el acuífero semiconfinado profundo. El resultado es una disminución de la evapotranspiración freática, del flujo al arroyo de la Rocina y de la frecuencia de inundación de las lagunas. La substitución del bosque de eucaliptus por vegetación nativa puede elevar los niveles freáticos e incluso reactivar antiguos "caños" tributarios al arroyo de La Rocina.

    Element load, conventional biomarkers and altered protein expression profiles were studied in Carcinus maenas crabs, to assess contamination of 'Domingo Rubio' stream, an aquatic ecosystem that receives pyritic metals, industrial contaminants, and pesticides. Lower antioxidative activities - glucose-6-phosphate and 6-phosphogluconate dehydrogenases, catalase - were found in parallel to higher levels of damaged biomolecules - malondialdehyde, oxidized glutathione -, due to oxidative lesions promoted by contaminants, as the increased levels of essential - Zn, Cu, Co - and nonessential - Cr, Ni, Cd - elements. Utility of Proteomics to assess environmental quality was confirmed, especially after considering the six proteins identified by de novo sequencing through capLC-muESI-ITMS/MS and homology search on databases. They include tripartite motif-containing protein 11 and ATF7 transcription factor (upregulated), plus CBR-NHR-218 nuclear hormone receptor, two components of the ABC transporters and aldehyde dehydrogenase (downregulated). These proteins could be used as novel potential biomarkers of the deleterious effects of pollutants present in the area. - Pollution assessment at 'Domingo Rubio' stream (Spain).

    Solving the phase problem in protein X-ray crystallography relies heavily on the identity of the crystallized protein, especially when molecular replacement (MR) methods are used. Yet, it is not uncommon that a contaminant crystallizes instead of the protein of interest. Such contaminants may be proteins from the expression host organism, protein fusion tags or proteins added during the purification steps. Many contaminants co-purify easily, crystallize and give good diffraction data. Identification of contaminant crystals may take time, since the presence of the contaminant is unexpected and its identity unknown. A webserver (ContaMiner) and a contaminant database (ContaBase) have been established, to allow fast MR-based screening of crystallographic data against currently 62 known contaminants. The web-based ContaMiner (available at http://strube.cbrc.kaust.edu.sa/contaminer/) currently produces results in 5 min to 4 h. The program is also available in a github repository and can be installed locally. ContaMiner enables screening of novel crystals at synchrotron beamlines, and it would be valuable as a routine safety check for 'crystallization and preliminary X-ray analysis' publications. Thus, in addition to potentially saving X-ray crystallographers much time and effort, ContaMiner might considerably lower the risk of publishing erroneous data.

    A test site was chosen for the purpose of elaborating the patterns for the future total use of the satellite photographs. The election of the test site was made with the following criteria in mind: (1) a flat terrain for eliminating the dangers of shadows produced by a difficult topography; and (2) searching of well defined natural limits for the test site. Due to the lack of satellite photographs from the study area, a number of photos from the northern area of Spain have been studied from the point of view of obtaining answers from the spectra of the vegetation masses.

    Full Text Available El Cuerpo de Ingenieros Militares es una de las instituciones más interesantes de las creadas en la España del siglo XVIII. Fundado por Felipe V en 1711, a imitación de su homónima francesa, tuvo un carácter principalmente militar. Nació como un grupo de técnicos, altamente cualificados ai servicio de la Corona, para la defensa del territorio sobre la que ésta gobernaba. Su principal función era la mejora de los sistemas defensivos, pero su labor también llevará a un mejor conocimiento del territorio y sus comunicaciones. Serán los encargados de la construcción y reparación de fortificaciones, canales, caminos y puertos y del levantamiento de planos. A estas actividades se le unirán las derivadas de los intereses económicos y sociales de la Corona, expresadas en la construcción de fábricas y otros edificios de carácter civil y religioso. Muchas de sus ideas quedaron en simples proyectos, pues nunca llegaron a materializarse. A pesar de ello, dichos proyectos son de gran importancia por las consecuencias que tuvieron para el desarrollo de la arquitectura española de la segunda mitad del siglo XVIII y de principios del xix. Frente al recargamiento del barroco de la época, los ingenieros primarán en sus obras lo funcional y racional, frente a lo ornamental y accesorio, facilitando la difusión del sobrio y severo neoclasicismo.

    Full Text Available A Reforma Gerencial trouxe para o setor público práticas e sistemas de gestão utilizados, tradicionalmente, nas empresas privadas, com o objetivo de melhorar a qualidade da prestação de serviços à sociedade. Desta forma, o objetivo desta pesquisa foi o de verificar como está sendo utilizado o Balanced Scorecard (BSC pelos Tribunais de Contas Estaduais brasileiros como metodologia para execução de seus planejamentos estratégicos. O instrumento de coleta de dados foi os planejamentos estratégicos dos Tribunais de Contas; analisaram-se os relatórios das cortes de contas dos seguintes Estados: Ceará (CE, Pernambuco (PE, Pará (PA, Minas Gerais (MG, Rio Grande do Sul (RS e Santa Catarina (SC. A amostra selecionada é não paramétrica, intencional e foi selecionada a partir do Relatório de Cumprimento de Metas do PROMOEX. Conclui-se que os Tribunais de Contas Estaduais, da amostra estudada, possuem uma estrutura semelhante na utilização do BSC. O desenvolvimento de perspectivas e indicadores ocorreu de forma semelhante, visto que do total dos indicadores desenvolvidos pelos seis tribunais 83% se repetem entre as cortes de contas, com frequências que variam de 33,3% a 100%; bem como se identificou a mesma deficiência em todos os tribunais estudados: a não evidenciação das metas a serem seguidas.

    Full Text Available Este artigo expõe uma abordagem sobre a importância do Sistema de Contas de Compensação na análise e avaliação do patrimônio das entidades. O Balanço Patrimonial, de acordo com o Decreto-Lei nº 2.627, de 26/09/1940, demonstrava os Sistemas de Contas Patrimoniais e de Compensação. Todavia, com o advento da Lei nº 6.404, de 15/12/1976, o Sistema de Contas de Compensação foi sacado da Estrutura do Balanço Patrimonial passando a constar as informações, apenas, em Notas Explicativas de rodapé de Balanço, em detrimento de informações relevantes de interesse dos diversos públicos usuários dessas Demonstrações Contábeis. A Lei nº 11.638, de 28/12/2007, que alterou alguns dispositivos da Lei nº 6.404/76, manteve esse mesmo tratamento previsto na Lei nº 6.404/76 dispensado para as Contas de Compensação. Assim, na tentativa de demonstrar a sua importância e provável impactação no patrimônio das entidades, os atos administrativos de natureza contábil são aqui abordados de forma elucidativa, através de exemplos práticos, evidenciando-se os riscos e suas consequências, decorrentes da omissão de seus registros e demonstrações contábeis.

    Full Text Available Na Administração Pública, a relação de contas tem papel importante para o adequado registro dos atos e fatos, bem como para a geração de informações, sendo desejável uniformidade na linguagem do plano de contas. Considerando as ações do Brasil e da Espanha para a instituição de um plano de contas nacionalmente padronizado, este trabalho tem por objetivo comparar as propostas de plano de contas discutidas pelos dois países e verificar se elas estão alinhadas aos padrões internacionais da contabilidade aplicada ao setor público. Trata-se de ensaio baseado em pesquisa bibliográfica e documental, que identificou como estes países vêm conduzindo o processo de convergência no setor público com relação à estrutura de suas contas, tendo como referencial as Normas internacionais de Contabilidade Aplicadas ao Setor Público (IPSAS em inglês. A justificativa para o estudo está na comparação de propostas de plano de contas de dois países pertencentes a continentes e blocos econômicos distintos, mas que possuem aspectos culturais e até mesmo línguas (português e espanhol semelhantes. O estudo mostrou que a proposta do Governo brasileiro está mais alinhada aos padrões internacionais, e que, comparativamente, há diferenças significativas entre esta e a proposta do Governo espanhol. Como o IFAC vem considerando tanto o Brasil como a Espanha em processo de convergência, há de se discutir se a estratégia dos países em atender as suas tipicidades locais na construção dos seus planos de contas não prejudicará o processo de adoção das IPSAS.

    Full Text Available O Tribunal de Contas lida todos os dias com processos que envolvem pessoas idosas, fato que o obriga a adoção de medidas que contribuam para a proteção desse grupo de pessoas. Essa obrigatoriedade é decorrência da vinculação das entidades públicas ao supraprincípio da dignidade da pessoa humana. Uma das formas de cooperar para proteção dos idosos, assim, é lhes conferir o direito à tramitação prioritária dos processos, que é medida de fácil implementação. O presente artigo, portanto, tem como objetivo demonstrar que os idosos têm o direito à tramitação processual preferencial no âmbito das Cortes de Contas.

Foi realizada uma pesquisa nos sítios do Governo de Pernambuco e no Tribunal de Contas do Estado de Pernambuco, no período de abril a maio de 2006. O universo da pesquisa compreendeu quatorze (14 prefeituras da região metropolitana do Recife. A amostra foi composta pelas prefeituras que, de 2000 a 2005, sofreram restrições nas prestações de contas pelo TCE/PE. A metodologia utilizada foi o estudo empírico-exploratório. Foram analisados 44 processos abertos pelo TCE, sendo que 20 destes não foram julgados, e, portanto, estavam sem pareceres na Internet. Concluiu-se que as ressalvas apresentadas nos pareceres do TCE-PE repetiram-se nos municípios, principalmente em 2001, apontando Falhas de Controles Internos.

    Full Text Available Resumo O presente artigo tem como proposta analisar a contação de histórias e a interação entre professora e crianças com ênfase na utilização dos recursos simbólicos - e, por conseguinte, a expansão da imaginação por meio do aporte teórico da Psicologia Histórico-Cultural. A pesquisa, de cunho qualitativo, utilizou, para a construção dos dados, observações e videogravação de episódios de contação de histórias em uma biblioteca escolar da Educação Infantil. Posteriormente, foram realizadas microanálises de episódios interativos. Os participantes da pesquisa foram 18 crianças entre 4 e 5 anos e 1 professora de biblioteca escolar da Educação Infantil. A contação de histórias, feita de forma interativa, potencializou o uso de recursos simbólicos quando os participantes fizeram referências às suas experiências cotidianas permeadas por afetividade - o que, consequentemente, desencadeou a expansão dos processos imaginativos.

    Full Text Available RESUMO: esta revisão integrativa da literatura objetivou identificar estudos sobre como o brincar simbólico/faz de conta de pré-escolares tem sido avaliado, quais os objetivos destes estudos e quais instrumentos têm sido utilizados para avaliar esse comportamento. Os dados foram coletados nas bases de dados CINAHL (Cumulative Index to Nursing and Allied Health Literature, PubMed, Web of Science, PsycINFO (Psychology Information, Scopus, e BVS (Biblioteca Virtual em Saúde, entre os anos 2009 e 2015, utilizando-se palavras-chave e descritores do DeCS (Descritores em Ciência da Saúde e do MeSH (Medical Subject Headings, em diferentes combinações: criança pré-escolar/child preschool; brinquedo terapêutico/play therapy; faz de conta/make believe/pretend play; jogo simbólico/symbolic play. A amostra final constituiu em 16 artigos. As publicações sobre o brincar simbólico/faz de conta de pré-escolares têm sido tênues, demonstrando que ainda há muito a avançar no assunto. Dentre os instrumentos citados verifica-se que o Child Initiated Pretend Play Assessment (ChIPPA foi o mais utilizado, estando presente em cinco artigos, envolvendo população diversa (deficiência cognitiva, lesão cerebral adquirida, paralisia cerebral e autismo. Os estudos focalizam, em sua maioria, crianças de desenvolvimento típico, objetivando obter um parâmetro para identificação do desempenho do brincar simbólico/faz de conta esperado, além de demonstrar que ao se avaliar este brincar é possível verificar outros aspectos importantes para o desenvolvimento infantil, como os emocionais e cognitivos, as habilidades sociais e de comunicação, possibilitando identificar possíveis déficits destas crianças e auxiliar os profissionais em suas práticas clínicas.

    Full Text Available Este ensaio é um acerto de contas com minha graduação em Administração. A partir de uma revisão de Tragtenberg (1980, Motta (1986 e Guerreiro Ramos (1989, pretende mostrar que as idéias apresentadas pelos autores de que a teoria das organizações é ideológica e ingênua contribuem para se compreender a posição (ideologia e os propósitos (instrumentos das teorias administrativas ensinadas em cursos de graduação. Uma vez que as ciências sociais passaram a teorizar em nível organizacional, sem considerar a totalidade social, libertaram-se dos desígnios da razão que constituíram sua motivação primeira, orientando-se por uma determinação estritamente instrumental e econômica. Os autores brasileiros revisados indicam que é somente recuperando o sentido original da razão e desvendando ideologias (como Motta se refere à obra de Tragtenberg que será possível construir um corpo teórico adequado à realidade, e acertar as contas com teorias ideológicas e ciências ingênuas.

    Full Text Available O presente artigo tem por objetivo o estabelecimento de algumas premissas acerca da independência das instâncias cíveis, administrativas e penais no ordenamento jurídico brasileiro, com enfoque para a discussão acerca da competência dos Tribunais de Contas para apreciação e julgamento de condutas que, embora consideradas atípicas sob a ótica criminal, podem ensejar prejuízo ao erário; discute-se, portanto, se tais condutas estariam (ou não desvencilhadas do controle externo (e técnico realizado pelas Cortes de Contas. O tema adquire relevância porque tem se tornado cada vez mais frequentes situações em que, concluído o processo criminal e assentada a atipicidade da suposta infração penal, os réus alegam a impossibilidade de apreciação do referido comportamento em sede de controle externo, sob o argumento de coisa julgada material ou non bis in idem. Esse entendimento não merece prosperar, vez que vigora em nosso ordenamento jurídico o princípio da independência de instâncias que, embora relativo, resguarda e fomenta a possibilidade de reexame da matéria por parte dos Tribunais de Contas nos casos em que a conduta realizada, conquanto não configure crime, pode ocasionar prejuízo ao erário. Pensar de forma diversa, isto é, defender uma intervenção mínima do direito criminal, por um lado, e cercear a atuação das demais searas jurídicas por outro, seria o mesmo que legitimar entre nós o absurdo, institucionalizando a impunidade em todas as esferas, o que já não se pode tolerar.

As sessões foram filmadas, transcritas e analisadas, buscando-se selecionar trechos representativos de capacidades das crianças, em suas várias manifestações. A análise das transcrições permitiu a identificação de capacidades das crianças, relativas a: a reconhecimento de objetos e criação de cenas; b criação de narrativas e faz-de-conta; c exploração de objetos por criança que usualmente recusava qualquer tipo de contato; d construção conjunta de significados. Considerou-se que as situações de brincadeira faz-de-conta proporcionaram o reconhecimento de habilidades que normalmente não seriam notadas em atividades cotidianas e/ou dirigidas. A interação entre parceiros e a situação de brincadeira relativamente livre, mediada por adultos, que buscavam principalmente facilitar e propiciar o brincar, proporcionou um ambiente favorável às múltiplas elaborações das crianças. Essa proposta, com foco no processo de construção de conhecimentos e habilidades permitiu descrever e promover o desenvolvimento das crianças com deficiência, mais do que caracterizá-las por suas incapacidades.The aim of the present study was to describe some modalities of pretend play in

    Full Text Available RESUMO Objetivo: avaliar pertinência e efetividade da tecnologia cuidativo-educacional "contação de histórias" como estratégia no cultivo do envelhecimento ativo (EA para usuários idosos de uma Unidade Básica de Saúde (UBS, da Amazônia. Método: Pesquisa Convergente Assistencial (PCA, realizada em UBS de Belém, estado do Pará, com oito idosas para testagem da tecnologia. Aplicou-se questionário de avaliação do EA e WHOQOL - breve, avaliação de qualidade de vida. Após capacitação com vistas à educação permanente, idosas contaram histórias para uma plateia que se manifestou respondendo à pergunta: "O que você tirou dela para a sua vida?" Resultados: histórias populares contadas provocaram reações das quais emergiram as categorias: Solidariedade; Respeito ao outro; Imaginação, sonhos, esperança e Cultura do imaginário amazônida. Tal prática resultou positiva, com mudança na qualidade de vida das idosas, no domínio psicológico. Conclusão: "contação de histórias" revelou-se uma tecnologia inovadora, recurso pertinente e efetivo à educação em saúde, especialmente para o envelhecimento ativo.

    Full Text Available Neste estudo buscou-se conhecer a evidenciação contábil de fundações privadas de saúde do município de Belo Horizonte, a partir da análise das prestações de contas destas entidades, do período de 2007 a 2011, e analisar a utilização do SICAP como instrumento de accountability. Fez-se uso da investigação qualitativa para verificar o nível de evidenciação contábil das demonstrações contábeis obrigatórias nas prestações de contas das três fundações privadas selecionadas para o estudo, a partir de um modelo de investigação que comparou os documentos elaborados para as prestações de contas às exigências mínimas das Normas Brasileiras de Contabilidade para a elaboração e apresentação de demonstrações contábeis das entidades sem fins lucrativos. Pode-se concluir que as entidades não atendem adequadamente as normas contábeis na evidenciação de suas demonstrações contábeis obrigatórias, conduzindo a uma inadequada evidenciação contábil nas prestações de contas apresentadas ao Ministério Público. Concluiu-se também que o SICAP não pode por si só ser considerado um instrumento adequado de accountability, visto que apresenta necessidade de melhoria e compatibilização às exigências das normas contábeis.

Para isto, utilizou como metodologia uma abordagem qualitativa, que envolve a pesquisa de campo com a coleta de dados realizada por meio da aplicação de questionários. Os resultados mostram que no processo de implementação da LAI foi realizado um plano de ações, porém, este não foi implementado, pois o governo federal disponibilizou um sistema de uso obrigatório para todos os órgãos do executivo federal. Em relação às perspectivas dos gestores, o item que parece ter mais chances de se realizar foi “mais transparência nas contas de contratos, balanços, relatórios de auditoria, etc.” Sobre os desafios, o item que mais se ressaltou foi “a falta de infraestrutura dos sistemas de informação e demais tecnologias”. Conclui-se que faltam ações de apoio do governo federal para a efetiva implementação da LAI.

A Constituição Federal de 1998, além de elencar o direito à saúde como um dos direitos fundamentais, ampliou as atribuições e competências do TCU, o que contribuiu para a fiscalização da efetivação deste direito por este órgão de controle. O presente artigo tem como objetivo apresentar a atuação fiscalizatória do TCU na área da saúde por meio da análise dos processos de fiscalização autuados durante os anos de 2011 a 2013. Constatou-se que os processos do tipo monitoramento foram os mais representativos (47,6%, seguidos dos de auditoria (31,9%. Quanto às temáticas tratadas nesses processos, a Atenção de Média e Alta Complexidade Ambulatorial e Hospitalar foi o objeto mais abordado pelas fiscalizações (32% e a de Investimentos na Rede de Serviços de Saúde, a segunda (12%. Há uma diversidade na atuação do TCU, o que reforça o seu papel na concretização do direito à saúde.

No âmbito do Estado do Ceará, o Tribunal de Contas do Estado do Ceará (TCE é o órgão de controle externo responsável por essa fiscalização, utilizando o Sistema Integrado de Contabilidade (SIC como ferramenta auxiliar na fiscalização dos jurisdicionados. Deste modo, objetivou-se no presente trabalho verificar a contribuição do SIC no contexto das atividades de controle externo exercidas pelos servidores do TCE. Para tanto, foi realizada inicialmente uma pesquisa bibliográfica acerca do controle externo, das competências do TCE e acerca do SIC. Em seguida, realizou-se uma pesquisa de campo, com aplicação de questionários junto aos servidores para a coleta dos dados sobre o sistema. Ressalte-se que o universo da pesquisa foi o total de servidores que executam atividades de controle, sendo adotado como critério na amostra intencional, a utilização do SIC no desenvolvimento dessas atividades. Após a coleta, esses dados foram trabalhados e estudados, sendo demonstrados os resultados obtidos com o auxílio de tabelas, quadros e gráficos. Ao término, foi possível delinear o perfil dos servidores que utilizam o SIC, bem como identificar a percepção destes quanto aos benefícios e limitações desse sistema. Constatou-se, portanto, que o SIC contribui positivamente para as atividades de controle externo mais relevantes do TCE, contudo, é preciso aperfeiçoá-lo em alguns pontos, bem como é necessário que os servidores aprofundem o seu conhecimento no SIC por meio de treinamentos, visando utilizá-lo de maneira mais eficiente.

    Full Text Available Resumo O presente artigo busca relações causais da renda e, principalmente, a taxa de câmbio sobre as despesas dos brasileiros que viajam ao exterior e sobre as receitas advindas dos turistas estrangeiros que visitam o nosso país, dados estes mensurados na conta de turismo no Balanço de Pagamentos do Brasil. Os testes econométricos indicam que as despesas, em média, são afetadas pela taxa de câmbio real, enquanto as receitas não são. Ao analisar esta assimetria foi possível constatar outra, onde provou-se que o número de turistas de países fronteiriços, tendo os visitantes da Argentina como exemplo, em média, são sensíveis à taxa de câmbio real, enquanto os visitantes de países de outros continentes, tendo o número de visitantes dos Estados Unidos como parâmetro, não são afetados, em média, pela taxa de câmbio real. Palavras-chave: economia do turismo; despesas de viagens internacionais; taxa de câmbio real. Abstract The present article looks for causal relations of the income and, especially, the exchange rate on the expenses of the Brazilians who travel abroad and on the revenues resulted from the foreign tourists who visit our country, these data measured in the account of tourism in the Brazilian Balance of Payments. Econometric tests indicate that the expenditure, on average, are affected by the real exchange rate, while the revenues are not. While analyzing this asymmetry it was possible to note another one, which proved that the number of tourists from bordering countries, taking the visitors of Argentina as an example, on average, are sensitive to the real exchange rate. On the other hand the visitors from countries of other continents, taking the number of visitors from the United States as a parameter, are not affected, on average, by the real exchange rate. Keywords: tourism economy; international travel account of balance of payments; real exchange rate.

    2015-06-01

    Full Text Available O ordenamento jurídico brasileiro consagra, em matéria de orçamento público, o princípio da precedência, pelo qual as peças orçamentárias devem ser elaboradas antes da sua aplicação. Portanto, a execução da despesa pública é precedida do planejamento. Porém, durante sua execução o orçamento deve ser adaptado para as situações que escapam a possibilidade de previsão quando da sua elaboração. Para isso, a Constituição prevê diversos mecanismos que permitem a adequação do orçamento à realidade. Alguns desses mecanismos visam adequar o orçamento às decisões administrativas, tal como uma reforma administrativa em que órgãos são extintos e/ou criados, enquanto outros devem ser utilizados para realizar correções no orçamento diante de falhas na previsão de receitas e fixação de despesas. Dentre esses instrumentos, destacam-se os créditos adicionais e, em se tratando de despesa não prevista originariamente no orçamento, o instrumento adequado é o crédito adicional especial. No presente trabalho, foi analisada a utilização de cada um desses mecanismos de alteração do orçamento público e, com base na legislação vigente e em conceituações doutrinárias, foram verificados quais são os requisitos e a finalidade de cada um, a fim de que se possa saber qual instrumento utilizar, de acordo com a situação apresentada. Foram feitas considerações, tendo em vista o posicionamento do Tribunal de Contas de Estado de Minas Gerais acerca dos créditos especiais, tendo por base quais são os requisitos legais para a correta discriminação da despesa no orçamento, a fim de que se conclua pela existência ou não de uma nova despesa.

    The Ria of Huelva (south-west Spain) is one of the most polluted fluvial-estuarine systems in the world. Industrial activity delivers huge amounts of pollutants to the local environment, particularly heavy metals and arsenic. Here we aimed to determine urinary levels of As, Cd, Cr, Cu and Ni in a representative sample (n=857) of adults living in the Ria of Huelva. Levels were compared to those from a representative sample of 861 adults of the general urban population of Andalusia (southern Spain) and multiple regression models were developed to identify individual factors associated with urinary levels of these elements. Arsenic levels were significantly higher in the Ria of Huelva as compared to other Andalusian cities, whereas Cd and Ni levels were significantly lower. Despite these differences, levels in both groups were similar to the reference values reported in previous studies for general population. Age, gender, diet and lifestyle were the major factors contributing to the interindividual variation in urinary metals. In conclusion, despite living in a highly polluted area, the population of the Ria of Huelva failed to show higher urinary levels of the studied metals as compared to a reference urban population of the same region.

    The present study seeks to estimate the impact of industrial emissions and harbour activities on total atmospheric deposition in an Atlantic coastal area in the southwest of the Iberian Peninsula. Three large industrial estates and a busy harbour have a notable influence on air quality in the city of Huelva and the surrounding area. The study is based on a geochemical characterization of trace elements deposited (soluble and insoluble fractions) in samples collected at a rate of 15 days/sample from June 2008 to May 2011 in three sampling sites, one in the principal industrial belt, another in the city of Huelva, and the last, 56 km outside Huelva city in an area of high ecological interest. The industrial emissions emitted by the Huelva industrial belt exert a notable influence on atmospheric deposition. Major deposition fluxes were registered for Fe, Cu, V, Ni, P, Pb, As, Sn, Sb, Se and Bi, principally in the insoluble fraction, derived from industrial funnel emissions and from harbour activities. Metals such as Mn, Ni, Cu and Zn, and elements such as P also have a significant presence in the soluble fraction converting them into potentially bio-available nutrients for the living organism in the ocean. A principal component analysis certifies three common emissions sources in the area: 1) a mineral factor composed mainly of elements derived from silicate minerals mixed with certain anthropogenic species (Mg, K, Sr, Na, Al, Ba, LREE, Li, Mn, HREE, Ti, Fe, Se, V, SO-, Ni, Ca and P); 2) an industrial factor composed of the same trace elements in the three areas (Sb, Mo, Bi, As, Pb, Sn and Cd) thus confirming the impact of the emissions from the Huelva industrial belt on remote areas; and 3) a marine factor composed of Na, Cl, Mg and SO.

No desenho das ARIs têm destaque os mecanismos que lhes conferem independência política, dada a natureza de suas atribuições e competências. Por outro lado, o TCU vem ampliando seu campo de atuação, passando a avaliar não mais apenas os aspectos formais da legalidade de procedimentos, mas também o desempenho e resultados alcançados por órgãos e entidades públicas. O TCU passa a atuar no acompanhamento e avaliação do desempenho das agências. O artigo analisa a interface entre independência e controle, discutindo possíveis conflitos institucionais entre as agências reguladoras e o TCU.This article analyzes the emergence of the independent regulatory agencies (IRAs in Brazil and their specificities as to their institutional design. It also discusses the recent developments in the Federal Court of Accounts' actions within the new public management context. IRAs were designed with emphasis on the features that give them political independence, considering the nature of their attributions and capabilities. On the other hand, the Federal Court of Accounts (FCA has broadened its area of activities, assessing not only the formal aspects of the legality of procedures, but also the performance and the results of organisms and public institutions. The FCA is tracking and assessing the agencies' performance. The article analyzes the interface between independence and control, discussing possible institutional conflicts between regulatory agencies and the FCA.

Neste contexto, a auditoria contábil tem um papel importante na análise das práticas administrativas adotadas pelas entidades. Desse modo, o objetivo deste artigo é comparar a estruturação dos controles internos no contas a receber e a pagar nas empresas Beta Ltda, a qual não contrata serviços de auditoria externa, e Alfa Ltda, que os contrata. Este estudo caracteriza-se como de caso comparativo de caráter descritivo por meio de questionário e entrevista. Os resultados apontam que a empresa Alfa Ltda tem melhores níveis de controle interno e, consequentemente, está menos exposta a erros e fraudes. Desse modo, entende-se que os seviços de auditoria atuam como um instrumento de auxílio para minimização dos riscos operacionais e servem de alerta aos gestores quanto à eficiência das transações. Contudo, percebe-se que a qualidade dos controles internos nas organizações depende diretamente da utilização de procedimentos de monitoramento.The constant need for excellent business performance triggers the quest for information quality and reliability to help in decision making. Considering this context, accounting auditing plays an important role in the analysis of administrative practices adopted by entities.

    Full Text Available Este artigo analisa as transformações das últimas décadas nos tribunais de contas no Brasil, à luz da discussão da temática do desenvolvimento institucional. Essa perspectiva analítica permite olhar os processos de mudanças nas arenas políticas, no longo prazo, enfatizando não só a resistência dos atores institucionais ou sociais com poder de veto e os mecanismos de path dependence, mas igualmente as conjunturas críticas que permitem levar adiante as transformações, mesmo que de forma incremental. No caso em estudo, a conjuntura crítica da democratização e da Constituição de 1988 trouxe mudanças, mas estas foram neutralizadas pela capacidade de veto da elite dirigente especialmente em alguns tribunais. Por outro lado, a nova conjuntura crítica representada pela Lei de Responsabilidade Fiscal, de 2000, alterou a dinâmica política e institucional, permitindo que, até muito recentemente, as mudanças que permaneciam bloqueadas começassem, a partir de então, a ser efetivadas diante da menor capacidade de exercício de tais vetos.This article analyzes the transformations of Brazilian courts of account since the democratization process occurred in the 1980s. The theoretical perspective of institutional development allows us to consider the long-term processes of political change, stressing not only the resistance of institutional and social actors, the situation of path dependence, but also the critical junctures. In this article, the changes brought by the 1988 Constitution in the courts of accounts structure were neutralized by the veto of powerful actors. Only a new critical juncture of the 2000 Fiscal Responsibility Law could alter the political and institutional dynamics and put into practice new changes in these institutions.

    Full Text Available A partir do processo de reforma e de modernização, o Estado redefiniu seu papel, deixando de ser o responsável exclusivo pelo desenvolvimento social e econômico, por meio da produção de bens e serviços, para se adaptar a uma nova função de “Estado Gerencial”. Essa reforma priorizou a transferência de determinadas atividades para o setor privado. A transparência do Estado se realiza por meio do acesso dos cidadãos às informações governamentais, o que torna mais democrática e estreita as relações entre o Estado e a sociedade civil. Neste artigo, buscou-se demonstrar como a Transparência das Contas Públicas (TCP pode inibir a prática da corrupção na gestão pública através da influência do controle social. Reconhece-se a TCP como um meio de informação social que deve ser adequado ao entendimento do público-alvo. Nesse sentido, o principal objetivo deste estudo é evidenciar a relação entre Estado, transparência e controle social como formas de combate à corrupção. O propósito específico está em contribuir para o aprofundamento do debate sobre as estratégicas mais adequadas para a implantação de um programa que possibilite um controle eficaz contra a corrupção no País. Como resultado, o estudo apresenta reflexões sobre a necessidade de que a sociedade exerça sua cidadania, o que levará a pressionar os gestores públicos a atenderem à legalidade e a realizarem uma administração responsável.

    Spanish strawberries are an export success. Spain is the second largest producer of this fruit and it has been the world's leading strawberry exporter for years. In 2012, strawberry exports were approximately 95% of total strawberry production in Spain. The production of the red gold is concentrated in around 7000 hectares of intensive farming in the province of Huelva (south west Spain). At least 85% of all Spanish strawberries are produced in this region, in an area close to the UNESCO World Heritage Site Doñana National Park. The case of the strawberry production in Huelva makes an interesting case study for the integrated analysis of the water-food-land-political economy nexus. Its combination of bio-physical and socio-economic characteristics (local climatic conditions, agricultural techniques, environmental issues, food value chains, trade networks and socio-economic factors) are quite particular and form a case where social and natural issues coevolve. Supporters of the activity argue a high contribution to local GDP and job market and its strategic position in international markets. Critics maintain that this industry creates social and environmental conflicts. The strawberry from Huelva supplies early season strawberries to the richer markets of Germany and France and at the same time seems to fail in alleviating a provincial unemployment rate of 34%. The viability of the system is in danger: production costs are 70% higher than 20 years ago while the price per kilo has not changed or even decreased. In environmental terms, the strawberries of Huelva are irrigated with ground water withdrawn from aquifers that feed the water streams of the natural park. Half of the wells that extract the water are not legally registered for what the total amount of water withdrawal remains unknown. Should we promote the continuity of this activity? In this work, I perform a Multi-Scale Integrated Assessment of Societal and Ecosystem Metabolism (MuSIASEM) of Water for the

    To describe the geographic distribution patterns of the municipal incidence of the most common tumours in the Huelva province (Spain) as compared to the estimated incidence for all of Spain. Relative risk (RR) was computed based on the conditional autoregressive model proposed by Besag, York and Mollié by applying the INLA tool to the cancer data for 2007-2011 for the following tumour locations: colon, rectum and anus (men and women); trachea, bronchia, and lungs, prostate and bladder in men; and breasts in women. The RR was presented in in choropleth and isopleth (with kriging interpolation) risk maps. RR for bladder cancer in men was greater than 1.0 in all municipalities, with confidence intervals over 1.0 in four municipalities; Madrid having a 1.56 RR (95%CI 1.30-1.67). For prostate cancer, a posteriori probabilities were below 0.1 in 68 of the 79 municipalities. For lung cancer, nine municipalities had confidence limits below 1.0, almost all of them in western Spain. For women, the RR for breast cancer was significantly higher in the capital of province area. The cancer incidence rates for the Huelva province were, in general, similar to those estimated for Spain, standing out bladder cancer in men (35% higher) and prostate cancer (30% lower). In the Huelva province, there is a geographical municipal distribution of cancer incidence with well-defined patterns for some specific tumour locations, with overall incidence rates very similar to those in the rest of Spain.

    The Huelva Estuary in Huelva, Spain, has been one of the most studied environmental compartments in the past years from the point of view of naturally occurring radioactive material (NORM) releases. It has been historically affected by waste releases, enriched in radionuclides from the U-decay series, from factories located in the area devoted to the production of phosphoric acid and phosphate fertilizers. Nevertheless, changes in national regulations forced a new waste management practice in 1998, prohibiting releases of phosphogypsum into the rivers. The input of natural radionuclides from phosphate factories to rivers was drastically reduced. Because of this there was a unique opportunity for the study of the response of a contaminated environmental compartment, specifically an estuary affected by tidal influences, after the cessation of the contaminant releases to, in this case, the Huelva Estuary (henceforth referred to as the Estuary). To investigate the environmental response to this new discharge regime, the specific activities of radionuclides 226 Ra and 210 Pb in water and sediment samples collected in four campaigns (from 1999 to 2005) were determined and compared with pre-1998 values. From this study it is possible to infer the most effective mechanisms of decontamination for the Estuary. Decontamination rates of 210 Pb and 226 Ra in the sediments and water have been calculated using exponential fittings and corresponding half-lives have been deduced from them. The cleaning half-life in the whole area of the Estuary is about 6 and 3.5 years for 226 Ra and 210 Pb respectively. The observed trend clearly shows that contamination of the Estuary by natural radionuclides is now decreasing and radioactive levels in waters and sediments are approaching the natural background references. This work attempts to evaluate whether it can be expected that the decontamination of the enhanced levels of natural radioactivity in the Estuary can be performed via natural

    Highlights: → Huelva estuary is affected by former phosphogypsum releases and pyrite acid mine drainage. → Time evolution of uranium concentration is analyzed after halting of NORM releases. → Two new contamination sources are preventing the complete uranium cleaning: (1) The leaching of phosphogypsum stacks located close to Tinto River. (2) Pyrite acid mine drainage. → High uranium concentrations are dissolved in water and precipitate subsequently. - Abstract: After the termination of phosphogypsum discharges to the Huelva estuary (SW Spain), a unique opportunity was presented to study the response of a contaminated environmental compartment after the cessation of its main source of pollution. The evolution over time of uranium concentrations in the estuary is presented to supply new insights into the decontamination of a scenario affected by Naturally Occurring Radioactive Material (NORM) discharges. The cleaning of uranium isotopes from the area has not taken place as rapidly as expected due to leaching from phosphogypsum stacks. An in-depth study using various techniques of analysis, including 234 U/ 238 U and 230 Th/ 232 Th ratios and the decreasing rates of the uranium concentration, enabled a second source of uranium contamination to be discovered. Increased uranium levels due to acid mine drainage from pyrite mines located in the Iberian Pyrite Belt (SW Spain) prevent complete uranium decontamination and, therefore, result in levels nearly twice those of natural background levels.

    Full Text Available The aim of this research was to evaluate the effect of the inoculation date of arbuscular mycorrhizal fungi on the fruit quality and the content of phytochemicals in a strawberry soilless growing system. The experiment was performed in Huelva (Spain and was conducted in a greenhouse on the La Rábida Campus of Huelva University under natural light and temperature from October 2013 to June 2014. Three short-day strawberry cultivars (‘Splendor’, ‘Sabrina’ and ‘Fortuna’ were grown in polyethylene bags filled with coconut fibres. Randomized block design, with 3 repetitions and factorial arrangement (3 cultivars x 3 treatments, was established. Each replicate consisted of one bag with 12 plants supporting structures at 40 cm height. The treatments were: T1 = mycorrhizal inoculation in the transplantation; T2 = mycorrhizal inoculation 30 days after transplantation (DAT; and T0 = control treatment, without inoculation. Arbuscular mycorrhizal fungi inoculation significantly affected the contents of anthocyanin and phenolics. When the inoculation is performed in the transplantation, the fruits showed a high content of anthocyanin and total phenolics. The mycorrhizal inoculation influences decreasing the acidity in fruit throughout the growing season and increase firmness only during the early stage of production.

In an attempt to determine sediments toxicity, a combination of exposure biomarkers was analyzed in both species: metallothionein-like-proteins (MTLPs), ethoxyresorufin O-deethylase (EROD), glutathione S-transferase activity (GST), glutathione peroxidase (GPX) and glutathione reductase (GR). In parallel, physical and chemical characterization of the different sediments was performed and biological responses related to the contaminants. Significant induction of MTLPs was observed when organisms were exposed to metal contaminated sediments (port of Huelva), and EROD and GPX activities after exposure to sediments containing organic compounds (port of Bilbao and Pasajes). No significant interspecies differences were observed in biomarker responses except for the GST and GR. - A battery of biomarkers shows exposure to metals and organic compounds.

    A detailed physical and chemical characterization of coarse particulate matter (PM10) and fine particulate matter (PM2.5) in the city of Huelva (in Southwestern Spain) was carried out during 2001 and 2002. To identify the major emission sources with a significant influence on PM10 and PM2.5, a methodology was developed based on the combination of: (1) real-time measurements of levels of PM10, PM2.5, and very fine particulate matter (PM1); (2) chemical characterization and source apportionment analysis of PM10 and PM2.5; and (3) intensive measurements in field campaigns to characterize the emission plumes of several point sources. Annual means of 37, 19, and 16 microg/m3 were obtained for the study period for PM10, PM2.5, and PM1, respectively. High PM episodes, characterized by a very fine grain size distribution, are frequently detected in Huelva mainly in the winter as the result of the impact of the industrial emission plumes on the city. Chemical analysis showed that PM at Huelva is characterized by high PO4(3-) and As levels, as expected from the industrial activities. Source apportionment analyses identified a crustal source (36% of PM10 and 31% of PM2.5); a traffic-related source (33% of PM10 and 29% of PM2.5), and a marine aerosol contribution (only in PM10, 4%). In addition, two industrial emission sources were identified in PM10 and PM2.5: (1) a petrochemical source, 13% in PM10 and 8% in PM2.5; and (2) a mixed metallurgical-phosphate source, which accounts for 11-12% of PM10 and PM2.5. In PM2.5 a secondary source has been also identified, which contributed to 17% of the mass. A complete characterization of industrial emission plumes during their impact on the ground allowed for the identification of tracer species for specific point sources, such as petrochemical, metallurgic, and fertilizer and phosphate production industries.

    Full Text Available En el espacio de integración de la Unión Europea persisten las fronteras, ya sin las dificultades y barreras de antaño, pero manteniendo numerosos símbolos y elementos del patrimonio cultural que siguen marcando una diferencia. Son líneas divisorias y, a la vez, franjas de territorios de transición con un importante patrimonio natural y cultural que se convierten ahora en recursos de atracción para novedosas demandas turísticas. Por ello, se estudia ya el turismo de frontera como un nuevo producto donde el recurso de la frontera y la historia es el principal atractivo y destino, aunque de forma complementaria a otros recursos y productos turísticos. Al margen de otros territorios y destinos fronterizos de Europa o del mundo, nuestra preocupación investigadora se centra en la Raya luso-española, en su extremo sur, en el Bajo Guadiana, en espacios que participan del Algarve, Baixo Alentejo y Huelva. En este territorio se conjugan destinos turísticos consolidados (Algarve y Costa Occidental de Huelva con un interior muy próximo e ignoto para la mayor parte de los turistas alojados en ese borde costero, a apenas unas decenas de kilómetros. Sin embargo, en los últimos años, un incipiente espacio turístico parece abrirse tierras adentro (y aguas desde la costa.

    Full Text Available This article aims to contribute to an exploration of the relations between familial memories and life course, especially stressing their dialogical and dynamic features. The focal point of this approach is the recognition that, on the one hand, family stories are subject to change over time and deeply rooted in personal biographies. On the other hand, the memory is a central element of the individual's life course, which itself involves the possibility to know, live, remember and share meaningful experiences. A family linked to fado serves as an empirical illustration.

    Combined-cycle plants are arguably the least well-known electrical plants, but in Spain they account for 25% of the country’s installed capacity. There are ten units based on this technology, manufactured by Siemens: two in Campo de Gibraltar (Cádiz), three in Palos de la Frontera (Huelva), two in Arrúbal (La Rioja) and three more in Sagunto (Valencia). Today, these plants continue to work as the most useful safeguard to guarantee Europe’s energy generation system, counted among the least contaminant fossil fuel combustion plants in the world. Their thermodynamic efficiency, in other words, the percentage of energy that can be obtained from the fuel, is around 60% (much higher than that generated by a coal-fired plant). (Author)

    Carbon capture and storage is increasingly being considered one of the most efficient approaches to mitigate the increase of CO2 in the atmosphere associated with anthropogenic emissions. However, the environmental effects of potential CO2 leaks remain largely unknown. The amphipod Ampelisca brevicornis was exposed to environmental sediments collected in different areas of the Gulf of Cádiz and subjected to several pH treatments to study the effects of CO2-induced acidification on sediment toxicity. After 10 days of exposure, the results obtained indicated that high lethal effects were associated with the lowest pH treatments, except for the Ría of Huelva sediment test. The mobility of metals from sediment to the overlying seawater was correlated to a pH decrease. The data obtained revealed that CO2-related acidification would lead to lethal effects on amphipods as well as the mobility of metals, which could increase sediment toxicity.

    2008-07-01

    Physical and chemical parameters of fresh berries from three southern high bush (ONeal, Sharp blue and Misty) blueberry cultivars grown in Huelva (Southwestern Spain) under two production systems were measured and evaluated. ANOVA applied to data yielded significant differences between production systems for mean fruit size and mean fruit fresh weight (P<0.05), although main effects on physical and chemical characteristics of fruit were due to cultivar. All three cultivars showed significantly different means (P<0.05) for fruit fresh weight, and all chemical characteristics. Stepwise discriminant analysis (SDA) for classification and identification of the cultivars based on physico-chemical properties of samples of fruits was performed. The model obtained gave high percentages of correct classification and prediction (81.1% and 78.4%, respectively). The variables with higher discriminating power were fruit titratable acidity, fruit size and fruit sugar content. (Author)

    This work explores the potential of multi-element fingerprinting in combination with advanced data mining strategies to assess the geographical origin of extra virgin olive oil samples. For this purpose, the concentrations of 55 elements were determined in 125 oil samples from multiple Spanish geographic areas. Several unsupervised and supervised multivariate statistical techniques were used to build classification models and investigate the relationship between mineral composition of olive oils and their provenance. Results showed that Spanish extra virgin olive oils exhibit characteristic element profiles, which can be differentiated on the basis of their origin in accordance with three geographical areas: Atlantic coast (Huelva province), Mediterranean coast and inland regions. Furthermore, statistical modelling yielded high sensitivity and specificity, principally when random forest and support vector machines were employed, thus demonstrating the utility of these techniques in food traceability and authenticity research.

    2016-02-29

    This paper presents a methodology and instrumentation system for the indirect measurement of the thermal diffusivity of a soil at a given depth from measuring its temperature at that depth. The development has been carried out considering its application to the design and sizing of very low enthalpy geothermal energy (VLEGE) systems, but it can has many other applications, for example in construction, agriculture or biology. The methodology is simple and inexpensive because it can take advantage of the prescriptive geotechnical drilling prior to the construction of a house or building, to take at the same time temperature measurements that will allow get the actual temperature and ground thermal diffusivity to the depth of interest. The methodology and developed system have been tested and used in the design of a VLEGE facility for a chalet with basement at the outskirts of Huelva (a city in the southwest of Spain). Experimental results validate the proposed approach.

    Profiles of artificial fallout (such as 137 Cs) and natural radioactivity radionuclides in sediment cores are useful tools to study sedimentological properties of different aquatic environments as well as to evaluate average sedimentation rates. In the Portil lagoon, a small natural reservoir located in Huelva province (southwest of Spain), and through the analysis of 210 Pb, 226 Ra, 137 Cs, 238 U and 210 Po vertical profiles in sediment cores, it is shown how the accumulative or transport character of the collection zones may be inferred. In the accumulation zone of the lagoon the influence of focusing effects has been analysed and an average sedimentation rate has been determined through 210 Pb in one sediment core. This 210 Pb-sedimentation rate is consistent with sediment dating based on the 137 Cs data. (author)

    The TTPIXE technique was used for the determination of the concentrations of major, minor and trace elements in phosphate rock and phosphogypsum samples. All the samples came from a fertilizer industry site in Huelva (SW of Spain). The analyses were done using proton beams from the 3 MV Van de Graaff accelerator of the 'Instituto Tecnologico e Nuclear' (ITN), Sacavem (Portugal). The aim was to obtain data about the distribution of the different elements in the process of P 2 O 5 production in the factory. The information obtained allowed evaluation of the effectiveness of the chemical treatment employed, and gave a detailed information about the elemental composition of phosphogypsum, the main by-product of phosphate fertilizer production. These data can be useful to define the phosphogypsum management and to evaluate its environmental impact

    Southern Europe, on the edge of the sunbelt, represents the ideal location for solar thermal generated power. Last year. SAWIE reported on the THESEUS project, a proposed 50 MWe solar thermal power plant for Frangokastello, southern Crete, which was submitted for support under the European Union`s THERMIE Programme. Funding was approved for the design phase for this innovative power plant, the first large-scale SEGS-style plant on European soil, at the end of last year. However, the THERMIE Programme also provided support for another Southern European plant, proposed by Colon Solar for Huelva in Southern Spain. Whilst hurdles remain to be overcome before both plants are built and commissioned, there is an excellent chance that by the start of the new Millennium, the solar collectors from these two plants could be generating over half a million MWh of energy a year. SAWIE compares the two projects. (author)

    An experimental infection with echinostomatid miracidia in sympatric or 'local' vs. allopatric or 'away' snail combinations, as a model to examine parasite compatibility, was carried out. We employed Euparyphium albuferensis miracidia to infect Gyraulus chinensis snails, from three different natural parks: Albufera (Valencia, Spain); the Ebro Delta (Tarragona, Spain) and Coto de Doñana (Huelva, Spain). Insignificant differences between the three snail strains were noted for the infection rate and the rhythm of daily cercarial production. However, a significantly higher total cercarial production per snail, patent period and life span were observed in local snails. The different infection characteristics in the three G. chinensis strains considered reveal that E. albuferensis miracidia demonstrate local adaptation.

    In the South of Spain, major industrial estates (e.g. Huelva) exist alongside ecologically interesting zones (e.g. Doñana National Park). Between June 2005 and June 2006, PM10 and PM2.5 were measured, for total mass, organic carbon (OC) and elemental carbon (EC) chemical composition, at a station in an ecologically interesting area located near Doñana National Park and an urban background area with industrial influence. The mean OC concentration is higher in the urban background (3.5 microg m(-3)) than in the rural monitoring station (2.8 microg m(-3)) as a consequence of local emissions (e.g. traffic). A total of 82% of TC is OC in the rural station, while the urban background station reveals 70% and 73% of TC in the PM10 and PM2.5 mass, respectively. The study of air-mass origin and characterization of carbonaceous species in the course of simultaneous sampling in rural and urban background monitoring stations differentiated three long-range air-mass transports: a North-African dust outbreak, Atlantic Advection and Continental (N-NW) episodes, the origins of the first and last of which are more heavily influenced by the anthropogenic emissions from industrial estates located around the city of Huelva (Punta del Sebo and Nuevo Puerto). Higher values were measured for OC and EC in the study area during the North-African dust outbreak, similar to those obtained during the Continental episode (N-NW), which was clearly influenced by industrial emissions, followed by the Atlantic Advection episodes. The comparison of carbon species with air-mass origin can help to discriminate the origin and source of particulate matter, as well as to determine the urban impact on rural areas.

  5. Variations in atmospheric PM trace metal content in Spanish towns: Illustrating the chemical complexity of the inorganic urban aerosol cocktail

    Moreno, Teresa; Querol, Xavier; Alastuey, Andrés; Viana, Mar; Salvador, Pedro; Sánchez de la Campa, Ana; Artiñano, Begoña; de la Rosa, Jesús; Gibbons, Wes

    The majority of the Spanish urban population breathe air containing inhalable ambient airborne particles at average concentrations of 30-46 μg m -3 (PM 10) and 20-30 μg m -3 (PM 2.5). Even though the average weight of inhaled urban aerosol is commonly similar, however, there can be large chemical differences between the ambient dusts from different towns, including the more bioreactive elements such as some metals. In this context, we compare the source-apportioned trace metal content of airborne PM 10 and PM 2.5 collected daily over a 1-year period from six population centres in Spain: Barcelona, Alcobendas, Llodio, Huelva, Tarragona and Las Palmas de Gran Canaria. Total average trace metal (ΣTM) PM 10 and PM 2.5 contents vary by up to a factor of around 3, reaching a maximum of ΣTM 10 811 ng m -3 and ΣTM 2.5 503 ng m -3 at Llodio, an industrial but humid site with the lowest PM 10 mass levels but high contamination by Zn, Pb, Mn, Sn, Ni and Cr. In contrast, pollution at Huelva, although another industrially influenced site, instead emphasises Cu and As, whereas Barcelona, where traffic emissions and resuspension contribute to some of the highest average PM 10 levels in Spain, has unusually raised levels of Ti, V and Ba. Such variations in both daily and annual average PM bulk chemistry, particularly in potentially toxic trace metals concentrated in the finer aerosols (such as Cd, As, Pb, Hg and Ni), predict that PM health effects on resident populations from different towns are unlikely to be the same.

In this setting, in recent years, there has been an exponential rise in the number of bariatric procedures, with approximately half of them performed in women of childbearing age, and a remarkable surge in the number of women who become pregnant after having undergone bariatric surgery (BS. These procedures entail the risk of nutritional deficiencies, and nutrition is a crucial aspect during pregnancy. Therefore, knowledge and awareness of the consequences of these techniques on maternal and fetal outcomes is essential. Current evidence suggests a better overall obstetric outcome after BS, in comparison to morbid obese women managed conservatively, with a reduction in the prevalence of gestational diabetes mellitus, pregnancy-associated hypertensive disorders, macrosomia, and congenital defects. However, the risk of potential maternal nutritional deficiencies and newborns small for gestational age cannot be overlooked. Results concerning the incidence of preterm delivery and the number of C-sections are less consistent. In this paper, we review the updated evidence regarding the impact of BS on pregnancy.

The results show that the caregiver profile is characterized by female between 50 and 55 years old, married, who has been caring for the sickly for 6 or 7 years, sharing the same home with the ill person with a lack of relief from family rotation. These caregivers often have little time for leisure and have, at times, had to leave their working life to cope with care. Resumen El objetivo de esta investigación consistió en conocer el perfil de los cuidadores de los enfermos de Alzheimer y otras demencias en la ciudad de Huelva. La muestra fue conformada por cuidadores de enfermos de Alzheimer de diferente sexo, edad, y condiciones sociales, familiares y laborales. Para la recogida de datos se elaboró un cuestionario que proporcionó la información necesaria. Los resultados indican que el perfil del cuidador comprende en lo fundamental características como: ser mujer de entre 50 y 55 años, estar casada, estar cuidando al enfermo entre 6 o 7 años, compartir el mismo domicilio con la persona enferma y no gozar de rotación familiar. Estas cuidadoras suelen tener poco tiempo para el ocio y en ocasiones han abandonado su vida laboral para asumir los cuidados.

    A detailed spatial and temporal assessment of urban NH3 levels and potential emission sources was made with passive samplers in six major Spanish cities (Barcelona, Madrid, A Coruña, Huelva, Santa Cruz de Tenerife and Valencia). Measurements were conducted during two different periods (winter-autumn and spring-summer) in each city. Barcelona showed the clearest spatial pattern, with the highest concentrations in the old city centre, an area characterised by a high population density and a dense urban architecture. The variability in NH3 concentrations did not follow a common seasonal pattern across the different cities. The relationship of urban NH3 with SO2 and NOX allowed concluding on the causes responsible for the variations in NH3 levels between measurement periods observed in Barcelona, Huelva and Madrid. However, the factors governing the variations in A Coruña, Valencia and Santa Cruz de Tenerife are still not fully understood. This study identified a broad variability in NH3 concentrations at the city-scale, and it confirms that NH3 sources in Spanish urban environments are vehicular traffic, biological sources (e.g. garbage containers), wastewater treatment plants, solid waste treatment plants and industry. The importance of NH3 monitoring in urban environments relies on its role as a precursor of secondary inorganic species and therefore PMX. Further research should be addressed in order to establish criteria to develop and implement mitigation strategies for cities, and to include urban NH3 sources in the emission inventories.

    Full Text Available Rural tourism is generally recognized as a booster for sustainable development of inland areas, but two researchactions would be necessary in advance: a local diagnosis of touristic processes and a risk assessment for those processes in affected areas. This article concerns the sociological and spatial risk analysis of urban sprawl in rural areas. As a case study, 29 municipalities in the southwest of the Iberian Peninsula (formed as a “comarca”, North of Huelva province are considered. Urban sprawl has been identified by specific literature as a threat for sustainable development in touristic areas, in coastal zones and in rural areas too. Based on the results of previous diagnosis, and the literature on socioenvironmental risks and impacts of residential tourism, two specific risk indicators are selected and analysed, in relation to local touristic models.El turismo rural es reconocido en Europa como un factor de desarrollo sostenible para las áreas de interior, secularmente deprimidas. Su éxito como tal va a depender de un diagnóstico a tiempo de sus procesos y de la evaluación de los riesgos que afectan a las áreas en las que aquellos se manifiesten. Este trabajo se centra en el análisis sociológico y espacial de los riesgos que la expansión urbanística en áreas de interior puede suponer para su desarrollo sostenible por medio del turismo rural. Como estudio de caso, se toman 29 municipios del suroeste de la península ibérica, conformados como comarca en el borde norte de la provincia de Huelva. A partir de los resultados de diagnósticos previos, y de la literatura sobre riesgos e impactos socioambientales del turismo residencial, se seleccionan dos indicadores de riesgo y se analiza su comportamiento en los modelos turístico-rurales existentes en la zona.

    The archeology and history of the ancient Mediterranean have shown that this sea has been a permeable obstacle to human migration. Multiple cultural exchanges around the Mediterranean have taken place with presumably population admixtures. A gravitational territory of those migrations has been the Iberian Peninsula. Here we present a comprehensive analysis of the maternal gene pool, by means of control region sequencing and PCR-RFLP typing, of autochthonous Andalusians originating from the coastal provinces of Huelva and Granada, located respectively in the west and the east of the region. The mtDNA haplogroup composition of these two southern Spanish populations has revealed a wide spectrum of haplogroups from different geographical origins. The registered frequencies of Eurasian markers, together with the high incidence and diversification of African maternal lineages (15% of the total mitochondrial variability) among Huelva Andalusians when compared to its eastwards relatives of Granada and other Iberian populations, constitute relevant findings unknown up-to-date on the characteristics of mtDNA within Andalusia that testifies a female population substructure. Therefore, Andalusia must not be considered a single, unique population. The maternal legacy among Andalusians reflects distinctive local histories, pointing out the role of the westernmost territory of Peninsular Spain as a noticeable recipient of multiple and diverse human migrations. The obtained results underline the necessity of further research on genetic relationships in both sides of the western Mediterranean, using carefully collected samples from autochthonous individuals. Many studies have focused on recent North African gene flow towards Iberia, yet scientific attention should be now directed to thoroughly study the introduction of European genes in northwest Africa across the sea, in order to determine its magnitude, timescale and methods, and to compare them to those terrestrial movements

    ABSTRACT: This research related to the theme of Childhood aims at contributing to the studies, which considers the child as a social actor. It has tried to examine the understandings from teachers who work with children from three to four years of age with make-believe games and the kinder cultures. The study subjects were eleven teachers from of primary education, among the twelve who made ​​up the universe of professionals working with children of the age group from three to four years old in municipal public institutions in the city of Gaspar / SC. The tool used in collecting the data was a structured interview with questions directed to the topic of research, which is qualitative. The data collection occurred between the months of April to June 2010. The results have indicated that the teachers understand the children’s make-believe games being the main activity in the institutional routine, including the games of make-believe in their class planning, also noticing the aspects of the kinder cultures brought by the children from non-institutional contexts to the make-believe. However, teachers as resources, strategies and ways of learning the content, using the activity from theater and music as solutions to develop the targeted activities, sometimes using the game of make-believe. The teachers perceive aspects from the kinder cultures brought by the children from non-institutional settings for make-believe games, primarily from the family context. For the teachers, the children make-believe is also seen as a mere imitation and not as an interpretive reproduction of the adults’ world.   Keywords: Child Education. Make-believe games.

Test how binary star systems evolve under Einsteins general theory of relativity!Unusual VariablesCataclysmic variables irregularly brightening binary stars consisting of an accreting white dwarf and a donor star are a favorite target among amateur astronomers: theyre detectable even with small telescopes, and theres a lot we can learn about stellar astrophysics by observing them, if were patient.Diagram of a cataclysmic variable. In an AM CVn, the donor is most likely a white dwarf as well, or a low-mass helium star. [Philip D. Hall]Among the large family of cataclysmic variables is one unusual type: the extremely short-period AM Canum Venaticorum (AM CVn) stars. These rare variables (only 40 are known) are unique in having spectra dominated by helium, suggesting that they contain little or no hydrogen. Because of this, scientists have speculated that the donor stars in these systems are either white dwarfs themselves or very low-mass helium stars.Why study AM CVn stars? Because their unusual configuration allows us to predict the behavior of their orbital evolution. According to the general theory of relativity, the two components of an AM CVn will spiral closer and closer as the system loses angular momentum to gravitational-wave emission. Eventually they will get so close that the low-mass companion star overflows its Roche lobe, beginning mass transfer to the white dwarf. At this point, the orbital evolution will reverse and the binary orbit will expand, increasing its period.CBA member Enrique de Miguel, lead author on the study, with his backyard telescope in Huelva, Spain.

    Measurements of the ambient aerosol were performed at the Southern coast of Spain, within the framework of the DOMINO (Diel Oxidant Mechanisms In relation to Nitrogen Oxides) project. The field campaign took place from 20 November until 9 December 2008 at the atmospheric research station "El Arenosillo" (37°5'47.76" N, 6°44'6.94" W). As the monitoring station is located at the interface between a natural park, industrial cities (Huelva, Seville) and the Atlantic Ocean, a variety of physical and chemical parameters of aerosols and gas phase could be characterized in dependency on the origin of air masses. Backwards trajectories were examined and compared with local meteorology to classify characteristic air mass types for several source regions. Aerosol number and mass as well as polycyclic aromatic hydrocarbons and black carbon concentrations were measured in PM1 and size distributions were registered covering a size range from 7 nm up to 32 μm. The chemical composition of the non-refractory submicron aerosol (NR-PM1) was measured by means of an Aerosol Mass Spectrometer (Aerodyne HR-ToF-AMS). Gas phase analyzers monitored various trace gases (O3, SO2, NO, NO2, CO2) and a weather station provided meteorological parameters. Lowest average submicron particle mass and number concentrations were found in air masses arriving from the Atlantic Ocean with values around 2 μg m-3 and 1000 cm-3. These mass concentrations were about two to four times lower than the values recorded in air masses of continental and urban origins. For some species PM1-fractions in marine air were significantly larger than in air masses originating from Huelva, a closely located city with extensive industrial activities. The largest fraction of sulfate (54%) was detected in marine air masses and was to a high degree not neutralized. In addition, small concentrations of methanesulfonic acid (MSA), a product of biogenic dimethyl sulfate (DMS) emissions, could be identified in the particle phase

Las actividades femeninas en lo religioso se manifiestan, a menudo, como una prolongación de las tareas domésticas y por tanto menos visibles y a veces menos valoradas, mientras que las actividades masculinas son más perceptibles, en cuanto se producen en lo público, un espacio reservado a la masculinidad. Por otra parte, el artículo se acerca a las asociaciones voluntarias más importantes de Andalucía -las hermandades- y a los rituales más relevantes que desde éstas se organizan. En este sentido, se analizan las procesiones, las romerías, las visitas a los santuarios o el sistema de promesas para poner de manifiesto como a pesar de que la presencia y participación femenina en los rituales religioso populares es muy importante, el papel predominante y protagonista es sin embargo masculino.Abstract: Based on ethnographic fieldwork carried out in the provinces of Huelva and Seville (Spain, this article reflects on the current situation, participation and aspirations of Andalusian women in Catholicism. Female activity in the religious sphere is shown to often manifest as an extension of domestic tasks and, as such, is seen as less visible and often less valued. The activities carried out by men, however, are more perceptible in that they are enacted in public, a space traditionally reserved for men. The article also considers Andalusia´s most important voluntary associations -the Brotherhoods- and the rituals most relevant to them. As such, the processions, religious pilgrimages, visits to sanctuaries as well as the system of asking for religious favours are analysed.

Important aspects of this process have been both the notable increase in the female prison population —Spain now has the highest number of female prisoners in Europe— and the presence of foreigners, highlighting the progressive increase in women immigrants from a variety of countries. This paper shows the sociological profile of imprisoned women for Spain in general, and Andalusia in particular; establishes their criminal profile, and analyses prison life from a perspective which recognises the specificity of gender and nationality. We have centred our field work on the prisons of Huelva, Algeciras (Cádiz and Alhaurín de la Torre (Málaga. We carried out in-depth interviews with professionals and foreign female inmates. With this in mind, we highlight the relevance of the field work carried out, held inside the prisons, in women’s units.

El contenido de su interior ha aportado, además de abundantes restos faunísticos, un depósito de cerámicas fenicias, griegas geométricas, sardas, libias, villanovianas y tartesias, principalmente formado por vajilla de mesa y ánforas, que testimonian tempranas redes de intercambio fenicias en el Mediterráneo Central y Occidental así como un temprano asentamiento fenicio. Las dataciones de C14 obtenidas con semillas del interior del pozo aportan una cronología hacia 925-900 cal AC al conjunto material, idéntica a las de tempranos asentamientos fenicios en la Península Ibérica como Huelva, El Carambolo y La Rebanadilla. En conjunto definen el horizonte más antiguo de la colonización fenicia en el Mediterráneo Central y Occidental.

    Full Text Available Introducción: Farmacovigilancia es la actividad de salud pública que tiene como objetivo la identificación, cuantificación, evaluación y prevención de los riesgos del uso de los medicamentos una vez comercializados, permitiendo así el seguimiento de los posibles efectos adversos. Según las últimas estadísticas del Centro Andaluz de Farmacovigilancia las notificaciones por farmacéuticos solo suponen el 9 % de las realizadas por los profesionales sanitarios. A la vista de estos datos se propuso un estudio para conocer los motivos de la falta de notificación y resolver los posibles problemas. Método: Se elaboró un cuestionario ad hoc, que se envió a todos los farmacéuticos de la provincia de Huelva. Resultados: Participaron 66 farmacéuticos. El 91 % conoce la tarjeta amarilla, dispone de ella el 45 %, conoce la vía web el 34 %, ha notificado alguna vez 34 % (7 % lo hace siempre que se encuentra una reacción adversa. El 60 % no ha notificado nunca y un 15 % piensa que no es obligatorio. Los motivos por los que no se notifica son falta de información 44 %, falta de formación 41 %, falta de tiempo 36 % y no disponer de tarjeta amarilla 29 %. Los titulares demandan una mayor información y formación. Los adjuntos ven la falta de tiempo como principal motivo de la no notificación. Discusión: Ante la poca notificación por los farmacéuticos y la importancia de este tema, se propone una campaña de concienciación entre los farmacéuticos de Huelva para mejorar estos resultados. Para ello se enviará a todos los colegiados un díptico formativo con la finalidad de resolver los principales inconvenientes de la notificación.

    Lead, cadmium, arsenic and nickel are present in the air due to natural and anthropogenic emissions, normally joined to particles. Human health and ecosystems can be damaged by high atmospheric levels of these metals, since they can be introduced in organisms via inhalation or ingestion. Small particles are inhaled and embebed in lungs and alveolus more easily than coarse particles. The CHIMERE model is a eulerian air quality model extensively used in air quality modelling. Metals have been recently included in this model in a special version developed in the CIEMAT modelling group (Madrid, Spain). Vivanco et al. (2011) and Gonzalez et al. (2012) showed an evaluation of the model performance for some metals in Spain and Europe. In these studies, metals were considered as fine particles. Nevertheless there is some observational evidence of the presence of some metals also in the coarse fraction. For this reason, a new attempt of modelling metals considering a fine (<2.5 μm) and coarse (2.5-10 μm) fraction has been done. Measurements of metal concentration in PM10, PM2.5 and PM1 recorded in Spain were used to obtain the new metal particle distribution size. On the other hand, natural emissions, not considered in the above mentioned studies, were implemented in the model, by considering metal emissions associated to dust resuspensiont. An evaluation of the new version is presented and discussed for two domains in Spain, centered on Barcelona and Huelva respectively. (Author)

    A method for the determination of Cd in natural water by flame atomic absorption spectrometry after separation and preconcentration with a bulk liquid membrane containing 2-acetylpyridine benzoylhydrazone as mobile carrier dissolved in toluene has been developed. Effects of carrier concentration, volume of organic phase and pH of feed and receiving solutions on the flux for Cd across the membrane have been studied, being optimized by the modified simplex method. Optimum values for these variables were: carrier concentration of 0.84 g l{sup -1}, 74 ml of toluene, pH 7.8 in the feed solution and 0.06 mol l{sup -1} of HNO{sub 3} in the receiving solution, allowing a preconcentration factor of 17.9. The preconcentration step required 7 h to be accomplished. The recovery of Cd at optimum conditions was 101.0{+-}2.7%, even with saline matrix, with good relative standard deviation (2.5%) at 95% confidence level. The detection limit of blank sample was 6 ng l{sup -1} of Cd. The method was validated using a certified reference material (TMDA-62) and also applied successfully to the analysis of Cd in four samples of seawater collected from the coast of Huelva (Spain). The relative errors of determinations were -7.6% for certified reference material and ranging between +2.4 and +7.1%, for samples of seawater (obtained between the results of the proposed and differential pulse anodic stripping voltammetry methods)

    The transfer and separation of Cu(II) ions across a bulk liquid membrane (BLM) containing pyridine-2-acetaldehyde benzoylhydrazone (2-APBH) as the mobile carrier dissolved in toluene has been investigated and optimised. The system was applied to the preconcentration of copper from natural waters prior to analysis by flame atomic absorption spectroscopy. The flux of copper across the membrane has been studied, and characterised as a function of analytical variables such as the carrier concentration, volume of organic phase, pH of feed and strip receiving solutions, stirring rate and temperature of solutions. The preconcentration yield at optimum conditions was 100.54{+-}0.94%, even with a high saline matrix (30 g l{sup -1} NaCl), with good precision (1.49%). A preconcentration factor of approximately 18 times could be obtained. The detection limit of a blank sample was 0.24 {mu}g l{sup -1} of Cu. The method was validated using a certified reference material (TMDA-62) and was applied successfully to the analysis of copper in two samples of seawater collected from the coast of Huelva (Spain). The relative errors were 2.42% for CRM and 0.48 and 3.66%, for seawaters (obtained between the results of the proposed and DPASV methods), respectively.

    This work shows the design, setup and performance of a new single radon detector calibration chamber developed at the University of Huelva (Environmental Radioactivity Group). This system is based on a certified radon source and a traceable reference radon detector, which allows radon concentrations inside the chamber radon to be obtained in steady-state conditions within a range of 400-22 000 Bq m -3 with associated uncertainties in the range of 4%. In addition, the development of a new ad hoc calibration protocol (UHU-RC/01/06 'Rachel'), which is based on the modelling of radon concentration within the chamber, allows it to be used without the reference detector. To do that, a complete characterization and calibration of the different leakage constants and the flow meter reading have been performed. The accuracy and general performance of both working methods for the same chamber (i.e., with and without the reference detector) have been tested by means of their participation in an intercomparison exercise involving five active radon monitors

    Full Text Available New results obtained from X-ray diffraction about structural transformations induced by vacuum between the different hydration states of three vermiculites (powdered and flake samples with different composition and origin, are presented. The dehydration process of the vermiculites under vacuum has been proved to be the same as that of temperature but with a different evolution through the different hydration states, although the zero-water layer hydration state has been not observed. The sample from Sta. Olalla, with the major content of Mg in the interlayer, exhibits the most complex behaviour.

    Se presentan nuevos resultados obtenidos mediante difracción de rayos X sobre las transformaciones estructurales que se producen en vermiculitas (en polvo y en lámina de exfoliación con distinta composición y procedencia, cuando se las somete a condiciones diferentes de presión y temperatura. El proceso de deshidratación de las vermiculitas que se produce bajo vacío es similar al que tiene lugar con aumento de la temperatura, es decir, se lleva a cabo mediante la formación de fases interestratificadas, aunque su evolución es diferente ya que nunca se alcanza el estado de hidratación de cero capas de agua en el espacio interlaminar. La muestra de Sta. Olalla (Huelva, con el mayor contenido de magnesio en dicho espacio, muestra el comportamiento más complejo.

    Full Text Available The technological convergence is leading to rapid change in the communicative context and, above all, education. In this sense, the present investigation tries to analyze a twofold: on the one hand, identify the skills of university professors to the digital humanities for social learning and, on the other hand, recognize the good university practices, to identify the most widely used tools, as well as the motivations that lead to success in the collaborative methodologies in Web 2.0. Following this, the research is focused through a qualitative-quantitative methodology with the collection of 537 questionnaires made up of students and the development of a focus groups with a total of 20 teachers belonging to the University of Cadiz, Seville and Huelva. In this sense, it can be noted, among the most outstanding results, that the use of new technologies in the classroom is taking a visible role, both from the point of view of the student and the professor for teaching in a collaborative manner and to develop a critical attitude to the current context. Therefore, it is important to establish that, in times of digital humanities teachers must seek to empower the university students so that they acquire skills how to enter critical discourses.

    Cardiovascular diseases are the first cause of death in Spain. The most usual procedures in interventional cardiology are coronariography and PTCA. The first is a diagnostic technique, and the second one is interventional. Our goal has been to study procedures made during the first six months in the Interventional Cardiology Unit of the Juan Ramon Jimenez Hospital (Huelva-Spain), taking into account radiation protection issues. We have studied 178 patients; 145 of them underwent coronariography, and 33 of the patients had PTCA too. Every case was analyzed taking into account technical and dosimetric parameters. We show parameters values gathered: Diagnostic techniques (valvular and non-valvular patients), and interventional techniques (coronariography and PTCA in different or in the same intervention). Higher doses were obtained with valvular patients, although the number of frames was similar. Attending to therapeutic procedures, the highest values were gotten with the 'double' interventions. Interventional procedures exceed in 60% doses gotten in diagnostic studies: this is because of the number of series and number of frames per series. Similar values obtained by other authors have been gotten. (author)

    Full Text Available The impact that future climatic conditions will have on agricultural productivity depends on the sensitivity to each environmental factor and relative changes in temperature, precipitation and UV-B radiation. The strawberry (Fragaria x ananassa is a microclimatic crop cultivated almost worldwide and Spain is the world's second-largest strawberry producer after the USA. Strawberry production in Huelva has been affected by climate change in recent decades. Temperature and solar radiation are primary environmental factors controlling short-day strawberry plant growth and development. Temperature is a limiting factor in crop productivity. We assessed the effect of variations in temperature and solar radiation on strawberry production and crop cycle duration. The study was carried out in commercial strawberry fruit production fields in the province of Huelva (Spain's southwestern coast. Fresh plants of cv. Camarosa were cultivated from October to June. The resulting crop was recorded weekly in the production field: early and total strawberry productions (g/plant, were recorded from January to March and from January to May, respectively. Data revealed that between early production and temperature (R²= 0.86 and between early production and solar radiation (R²= 0.73 there was a linear relationship. However, total production and temperature (R²= 0.69 and total production and solar radiation (R²= 0.69 were related by a quadratic relationship. Our estimates suggest that strawberry production could be affected by climate change. Due to the relationship between yield and temperature, and between yield and solar radiation, climate change scenarios were found to result in reductions in crop cycle duration.El impacto que las condiciones climáticas futuras tendrán en la productividad agrícola, depende de la sensibilidad de cada factor ambiental y de los cambios relativos en la temperatura, precipitación y radiación UV-B.

    Full Text Available Five sweet orange (Citrus sinensis Osbeck varieties cultivated in Huelva (Spain and picked at two seasons during two consecutive years, were characterized for their antioxidant activity (free radicals scavenging activity, reducing power and lipid peroxidation inhibition and vitamin content (vitamin E and vitamin C. The effects induced by sweet orange variety and stage of maturity were comprehensively compared by applying 2-way ANOVA and linear discriminant analysis. The results indicated higher differences in antioxidant activity and vitamin contents in response to the effect of the harvesting season, when compared to the effect of sweet orange variety. Nevertheless, the results observed in 2012 showed less marked differences among the assayed sweet orange varieties. Either way, it might be concluded that oranges sampled in January show the highest antioxidant activity and vitamin contents. Furthermore, concerning the properties evaluated in this work, all sweet orange varieties represent good alternatives, except for Rhode Summer, which would not be the preferable choice as a target to enhance sweet orange overall characteristics.

    This study provides geochemical data with the aim of identifying and quantifying the main processes occurring in an Acid Mine Drainage (AMD) affected estuary. With that purpose, water samples of the Huelva estuary were collected during a tidal half-cycle and ion-ion plots and geochemical modeling were performed to obtain a general conceptual model. Modeling results indicated that the main processes responsible for the hydrochemical evolution of the waters are: (i) the mixing of acid fluvial water with alkaline ocean water; (ii) precipitation of Fe oxyhydroxysulfates (schwertmannite) and hydroxides (ferrihydrite); (iii) precipitation of Al hydroxysulfates (jurbanite) and hydroxides (amorphous Al(OH)3); (iv) dissolution of calcite; and (v) dissolution of gypsum. All these processes, thermodynamically feasible in the light of their calculated saturation states, were quantified by mass-balance calculations and validated by reaction-path calculations. In addition, sorption processes were deduced by the non-conservative behavior of some elements (e.g., Cu and Zn). Copyright © 2014 Elsevier Ltd. All rights reserved.

    Full Text Available We analyzed the prokaryotic community structure of a saltern pond with 21 % total salts located in Isla Cristina, Huelva, Southwest Spain, close to the Atlantic ocean coast. For this purpose, we constructed a metagenome (designated as IC21 obtained by pyrosequencing consisting of 486 Mb with an average read length of 397 bp and compared it with other metagenomic datasets obtained from ponds with 19, 33 and 37 % total salts acquired from Santa Pola marine saltern, located in Alicante, East Spain, on the Mediterranean coast. Although the salinity in IC21 is closer to the pond with 19 % total salts from Santa Pola saltern (designated as SS19, IC21 is more similar at higher taxonomic levels to the pond with 33 % total salts from Santa Pola saltern (designated as SS33, since both are predominated by the phylum Euryarchaeota. However, there are significant differences at lower taxonomic levels where most sequences were related to the genus Halorubrum in IC21 and to Haloquadratum in SS33. Within the Bacteroidetes, the genus Psychroflexus is the most abundant in IC21 while Salinibacter dominates in SS33. Sequences related to bacteriorhodopsins and halorhodopsins correlate with the abundance of Haloquadratum in Santa Pola SS19 to SS33 and of Halorubrum in Isla Cristina IC21 dataset, respectively. Differences in composition might be attributed to local ecological conditions since IC21 showed a decrease in the number of sequences related to the synthesis of compatible solutes and in the utilization of phosphonate.

    Full Text Available Desde la dinastía Song en Oriente Medio, alrededor del siglo XII, los molinos de viento han sido protagonistas en la transformación de la energía eólica para ciertos trabajos mecánicos, como la extracción del agua o la molienda del cereal. En consecuencia, a lo largo de la historia se ha investigado sobre esta clase de patrimonio industrial desde diversos enfoques, aunque no siempre desde el punto de vista de la ingeniería. La metodología seguida tras realizar un inventario de los 89 ingenios eólicos ha sido obtener su modelo 3D, caracterizando el viento y finalizando con el estudio mecánico de sus principales parámetros de funcionamiento. El resultado ha sido su idoneidad para trabajar a bajas velocidades produciendo un par elevado gracias a la superficie expuesta del velamen al viento, y que los molinos de viento de Cádiz y Huelva presentaban un rendimiento eólico mayor al estar mejor diseñados que los de Almería.

En este contexto, la logística y organización comercial adquiere un papel relevante en la viabilidad de las explotaciones agrarias, ya que de ellas dependen, en gran medida, la rentabilidad económica.

    Full Text Available The aim of this study was to establish which final game actions discriminate final victories and defeats in women volleyball formative stages during ended sets, which are solved by regulation with a minimal advantage of two points. A total of 57 sets were analyzed in infantile category and 69 sets in cadet category during the national volleyball championship at school age (12-16, Valladolid 2008 and Huelva 2009. Statistics analysis shows differences between the condition of both the winner and the loser teams in sets in the positive attack in infantile category and in positive block and error in cadet category. Discriminative analysis, statistical test that determines those most significant game actions when establishing the differences existing between the winner and loser teams, shows how to predict victory and defeat in the ended sets regarding the positive attack, negative service and error in infantile category and positive block and error in cadet category. These ones suggest that during decisive set moments in both categories, either technical gestures control or errors which arise from a regulation infraction may predict their final performance.

    This research reports the effects of pH increase on contaminant mobility in phosphogypsum leachates by seawater mixing, as occurs with dumpings on marine environments. Acid leachates from a phosphogypsum stack located in the Estuary of Huelva (Spain) were mixed with seawater to achieve gradually pH7. Concentrations of Al, Fe, Cr, Pb and U in mixed solutions significantly decreased with increasing pH by sorption and/or precipitation processes. Nevertheless, this study provides insight into the high contribution of the phosphogypsum stack to the release of other toxic elements (Co, Ni, Cu, Zn, As, Cd and Sb) to the coastal areas, as 80-100% of their initial concentrations behaved conservatively in mixing solutions with no participation in sorption processes. Stable isotopes ruled out connexion between different phosphogypsum-related wastewaters and unveiled possible weathering inputs of estuarine waters to the stack. The urgency of adopting effective restoration measures in the study area is also stressed. Copyright © 2018 Elsevier Ltd. All rights reserved.

    A field study was carried out in the south of the Iberian Peninsula in an industrial area in the neighbourhood of Huelva city, SW Spain, and in a natural area (Donana National Park) for comparison, to estimate the genetic risk induced by environmental pollution in wild mice. Genotoxic effects in a sentinel organism, the Algerian mice (Mus spretus) free living in the industrial area were compared with animals of the same species living in the natural protected area. The single cell gel electrophoresis, or Comet assay, was performed as a genotoxicity test in peripheral blood of mice. Our results clearly show that mice free living in the contaminated area bear a high burden of genetic damage as compared with control individuals. The results suggest that the assessing of genotoxicity levels by the Comet assay in wild mice can be used as a valuable test in pollution monitoring and environmental conservation. - We have found an increased genotoxic damage in wild mice in a highly polluted area from industry, mining and agriculture in SW Spain, as assessed by the Comet assay.

    Full Text Available Marine tertiary materials of the Guadalquivir basin consist of four mayor depositional sequences of great continuity in the whole basin which are separate by unconformities. The lower outcroping unit (unit 2 ineludes glauconite-rich sandstones and marly limestones (Fm. Calcarenitas de Niebla, Tortonian-Messinian and Olisthostromic materials. This unit lies discordantly over the Paleozoic, and was sedimented in a shaUow marine platform. Olisthostromic materials (Mesozoic and Miocene, composed of sand and elayey sand, were deposited during Tortonian-Messinian times. As a consequence of a transgressive pulse, the sedimentation of a thick marly series (Fm. Arcillas de Gibraleón ofthe Messinian-Low Pliocene age took place. In the last stages of the filling of the basin (Pliocene a regression began, and sands and silts were deposited (Fm. Arenas de Huelva and Fm. Arenas de Bonares. Also, and as a final consequence of the regression stage, lacustrine sedimentary deposits (Upper Pliocene occur at the south of the basin, which are composed of marly limestone and greenish palygorskite and sepiolite marls. From a mineralogical point of view, autochthonous materials from this marine detritalcarbonate series, are mainly composed of calcite, quartz and phyUosilicates with minor dolomite and feldspars, and secondary gypsum. The elay minerals present are illite and smectite with minor kaolinite and chlorite. The evolution of the elay minerals associations varies from bottom to top as foUows: Illite or Clauconite >> Smectite > Chlorite/Kaolinite (Fm.

    Full Text Available The geomicrobiological characterization of the water column and sediments of Río Tinto (Huelva, Southwestern Spain have proven the importance of the iron and the sulfur cycles, not only in generating the extreme conditions of the habitat (low pH, high concentration of toxic heavy metals, but also in maintaining the high level of microbial diversity detected in the basin. It has been proven that the extreme acidic conditions of Río Tinto basin are not the product of 5000 years of mining activity in the area, but the consequence of an active underground bioreactor that obtains its energy from the massive sulfidic minerals existing in the Iberian Pyrite Belt. Two drilling projects, MARTE (Mars Astrobiology Research and Technology Experiment (2003–2006 and IPBSL (Iberian Pyrite Belt Subsurface Life Detection (2011–2015, were developed and carried out to provide evidence of subsurface microbial activity and the potential resources that support these activities. The reduced substrates and the oxidants that drive the system appear to come from the rock matrix. These resources need only groundwater to launch diverse microbial metabolisms. The similarities between the vast sulfate and iron oxide deposits on Mars and the main sulfide bioleaching products found in the Tinto basin have given Río Tinto the status of a geochemical and mineralogical Mars terrestrial analogue.

    This paper relates the calibration of a low background gas-flow proportional counter. This calibration has been used to determine low activity of "2"3"4Th in coastal water samples. Two methods were used to prepare calibration samples: Evaporation and Electrodeposition. First method was rejected due to the lack of reproducibility because the different geometry adopted by the drops of tracer once dried on the disk. On the contrary, through the second method, similar efficiencies were obtained in all detectors with an average of 0.401±0.004. In this paper, the whole procedure to obtain "2"3"4Th activity in dissolution as well as in particulate matter has been detailed, and all the algorithms needed to calculate activities and efficiencies are shown. Finally, two experiments have been designed in order to validate the calibration of the beta counter and the method to determine "2"3"4Th in coastal waters with high concentration of particulate matter. - Highlights: • This paper shows a Home-made calibration using two methods to prepare calibration samples. • The algorithms needed to obtain Th-234 activity concentrations are described in full detail. • This is the first time Th-234 has been determined in water samples from Huelva Estuary.

  2. Modelling the fine and coarse fraction of Pb, Cd, As and Ni air concentration in Spain

    Gonzalez, M. A.; Vivanco, M. G.

    2015-01-01

    Lead, cadmium, arsenic and nickel are present in the air due to natural and anthropogenic emissions, normally joined to particles. Human health and ecosystems can be damaged by high atmospheric levels of these metals, since they can be introduced in organisms via inhalation or ingestion. Small particles are inhaled and embebed in lungs and alveolus more easily than coarse particles. The CHIMERE model is a eulerian air quality model extensively used in air quality modelling. Metals have been recently included in this model in a special version developed in the CIEMAT modelling group (Madrid, Spain). Vivanco et al. (2011) and Gonzalez et al. (2012) showed an evaluation of the model performance for some metals in Spain and Europe. In these studies, metals were considered as fine particles. Nevertheless there is some observational evidence of the presence of some metals also in the coarse fraction. For this reason, a new attempt of modelling metals considering a fine (<2.5 μm) and coarse (2.5-10 μm) fraction has been done. Measurements of metal concentration in PM10, PM2.5 and PM1 recorded in Spain were used to obtain the new metal particle distribution size. On the other hand, natural emissions, not considered in the above mentioned studies, were implemented in the model, by considering metal emissions associated to dust resuspensiont. An evaluation of the new version is presented and discussed for two domains in Spain, centered on Barcelona and Huelva respectively. (Author)

    Mitigating climate change requires management strategies to reduce greenhouse gas emissions in any sector, including the health system. Carbon footprint calculations should play a key role in quantifying and communicating these emissions. Food is among the categories with low accuracy because the carbon footprint for food is still under development. We aimed to quantify the carbon footprint of different diets. Average carbon footprint for a normal diet was based on detailed composition data in Juan Ramón Jiménez Hospital (Huelva, Spain). In addition, the carbon footprints of 17 other therapeutic diets were estimated using a streamlined variation of each diet published by Benidorm Clinical Hospital (Spain). The carbon footprint was calculated for 18 hospital diets for a variety of patients. The reference menu corresponds to the normal diet provided to patients who do not have special dietary requirements. This menu has a low carbon footprint of 5.083 CO₂ eq/day. Hospital diets contribute to the carbon footprint of a hospital. The type of diet has a significant impact on the greenhouse gas emissions. A Mediterranean diet is associated with lower environmental impact than diets with more meat, in particular red meat. © The Author(s) 2014 Reprints and permissions: sagepub.co.uk/journalsPermissions.nav.

    Highlights: • Mixing of acid riverine water with alkaline seawater was studied in an estuary. • Combination of data and geochemical tools allowed modeling the water mixing. • The main geochemical processes were identified and for the first time quantified. • Water chemistry is the result of mixing, dissolution-precipitation and sorption. • Main reactions: gypsum and calcite dissolution and Al and Fe solids precipitation. - Abstract: This study provides geochemical data with the aim of identifying and quantifying the main processes occurring in an Acid Mine Drainage (AMD) affected estuary. With that purpose, water samples of the Huelva estuary were collected during a tidal half-cycle and ion–ion plots and geochemical modeling were performed to obtain a general conceptual model. Modeling results indicated that the main processes responsible for the hydrochemical evolution of the waters are: (i) the mixing of acid fluvial water with alkaline ocean water; (ii) precipitation of Fe oxyhydroxysulfates (schwertmannite) and hydroxides (ferrihydrite); (iii) precipitation of Al hydroxysulfates (jurbanite) and hydroxides (amorphous Al(OH) 3 ); (iv) dissolution of calcite; and (v) dissolution of gypsum. All these processes, thermodynamically feasible in the light of their calculated saturation states, were quantified by mass-balance calculations and validated by reaction-path calculations. In addition, sorption processes were deduced by the non-conservative behavior of some elements (e.g., Cu and Zn)

    This study presents a new volatile organic compounds (VOC) dataset measured during the DOMINO field campaign in December 2008. The measurements were made from a 10m tower located in a nature reserve on the south west coast of Spain. For the analysis, the VOCs were collected and concentrated on a thermal desorber unit, separated on a gas chromotagraph equipped with an enantiomerically selective column, and detected by mass spectrometry. This experimental set-up allowed the measurement of anthropogenic VOCs such as ethyl benzene, and all xylene isomers, and biogenic species such as isoprene and monoterpenes. Here we examine the VOC mixing ratio variations as a function of air mass origin to characterize the measurement site in terms of biogenic and anthropogenic influences. Mixing ratios of biogenic species were generally low, consistent with the low winter season growth rates. The ratio of (-)-alpha-pinene to (+)-alpha-pinene was variable but showed a clear dominance of the (-)-enantiomer, similar to previous results obtained with the same system in the Tropical rainforest. High mixing ratios of benzene and toluene were related to transport events from Seville (to the northeast) and Huelva (to the west). The ratio of two short lived anthropogenic species ethylbenzene and meta-xylene was found to peak at midday and indicative of the levels of oxidant levels.

    Onchocerca lupi causes ocular pathology of varying severity in dogs from south-western United States, western Europe and northern Asia. This filarioid has also been recognized as a zoonotic agent in Tunisia, Turkey, Iran and the USA, though the information about the biology and epidemiology of this infection is largely unknown. In Europe, O. lupi has been reported in dogs from Germany, Greece, Hungary, Portugal and Romania and in a cat from Portugal. The present study was designed to establish the occurrence of O. lupi in dogs in southwestern Spain. In the present study a total of 104 dogs of different breed, sex, and age living in a shelter in Huelva (SW Spain) were examined. Skin snip samples were collected using a disposable scalpel in the forehead and inter-scapular regions and stored as aliquots in saline solution (0.5 ml) before light microscopy observation of individual sediments (20 μl) and molecular examination. Of the 104 dogs examined, 5 (4.8 %) were skin snip-positive for O. lupi: two by microscopy and three by PCR. One of the O. lupi infected dogs showed neurological signs but ocular ultrasonography and/or MRI detected no abnormalities. This first report of O. lupi infection in dogs in southern Spain expands the range of geographical distribution of this parasite and sounds an alarm bell for practitioners and physicians working in that area.

    Describe the factors which can be associated with cognitive impairment in institutionalized and non-institutionalized elderly. Cross-sectional study of 200 people aged over 64 in Huelva (Spain) in 2014. Of these, 100 people were institutionalized in a residential facility and 100 were not. Cognitive impairment was assessed using the Mini-Mental State Examination (MMSE-35), basic activities of daily living by Barthel index, general health through the Goldberg GHQ-28 and social, clinical and behavioural variables were contemplated in the study. The association of cognitive impairment with all the variables was analysed using Chi-square test. Finally, a multivariate analysis was performed using logistic regression to identify possible joint influence of variables to study on the cognitive impairment. The prevalence of cognitive impairment in those institutionalized was 47%, higher than that of non-institutionalized group which was only 8% (p<.001). The dependence for basic activities for daily living and learning activities were the only variables in both groups which were associated with the cognitive impairment. Institutionalization (OR=5.368), age (OR=1.066) and dependence for basic activities (OR=5.036) were negatively associated with CI, while learning activities (OR=.227) were associated in a positive way. Conducting learning activities and the promotion of personal autonomy can delay cognitive impairment in older people. It is important to include cognitive stimulation programs aimed at the old population, especially in residential institutions. Copyright © 2015 Elsevier España, S.L.U. All rights reserved.

    The activities of the phosphate industry may lead to enhanced levels of naturally occurring radioactivity in terrestrial and freshwater ecosystems. We here perform a preliminary environmental risk assessment (ERA) of the activities of the phosphate industry (phosphate ore mining, phosphate fertilizer factories, phosphate export platforms). We evaluated the environmental impact of 5 phosphate fertilizer plants (located in Belgium, Spain, Syria, Egypt, Brazil) and one phosphate-mine and phosphate-export platforms in the harbour(both located in Syria). These sites were selected because of the enhanced concentrations of naturally occurring radionuclides in the surrounding environments. The ERICA non-human biota assessment tool was used to predict radiation dose rates to the reference organisms and associated risks. Reference organisms were those assigned as default by the ERICA Tool. Potential impact is expressed as a risk quotient (RQ) based on a radiation screening value of 10 μGy h{sup -1}. If RQ ≤ 1, the environment is unlikely at risk and further radiological assessment is deemed not to be required. For all the cases assessed, RQ exceeded 1 for at least one of the reference organisms. {sup 226}Ra or {sup 210}Po were generally the highest contributors to the dose. The aquatic ecosystems in the vicinity of the phosphate fertilizer plants in Tessenderlo (Belgium), Huelva (Spain), Goias (Brazil) and the terrestrial environment around the phosphate mine in Palmyra (Syria) are the ecosystems predicted most at risk.

    Daylight fireball video monitoring High-sensitivity video devices are commonly used for the study of the activity of meteor streams during the night. These provide useful data for the determination, for instance, of radiant, orbital and photometric parameters ([1] to [7]). With this aim, during 2006 three automated video stations supported by Universidad de Huelva were set up in Andalusia within the framework of the SPanish Meteor Network (SPMN). These are endowed with 8-9 high sensitivity wide-field video cameras that achieve a meteor limiting magnitude of about +3. These stations have increased the coverage performed by the low-scan allsky CCD systems operated by the SPMN and, besides, achieve a time accuracy of about 0.01s for determining the appearance of meteor and fireball events. Despite of these nocturnal monitoring efforts, we realised the need of setting up stations for daylight fireball detection. Such effort was also motivated by the appearance of the two recent meteorite-dropping events of Villalbeto de la Peña [8,9] and Puerto Lápice [10]. Although the Villalbeto de la Peña event was casually videotaped, and photographed, no direct pictures or videos were obtained for the Puerto Lápice event. Consequently, in order to perform a continuous recording of daylight fireball events, we setup new automated systems based on CCD video cameras. However, the development of these video stations implies several issues with respect to nocturnal systems that must be properly solved in order to get an optimal operation. The first of these video stations, also supported by University of Huelva, has been setup in Sevilla (Andalusia) during May 2007. But, of course, fireball association is unequivocal only in those cases when two or more stations recorded the fireball, and when consequently the geocentric radiant is accurately determined. With this aim, a second diurnal video station is being setup in Andalusia in the facilities of Centro Internacional de Estudios y

    Full Text Available Este artigo trata das transformações na substância do mérito a partir da perspectiva das empresas que utilizam anúncios de classificados de empregos visando à contratação de gerentes e executivos. Construiu-se uma base de dados com 400 anúncios coletados em jornais de circulação nacional e em bancos de empregos (job boards na Internet nos anos de 1990 e 2005. Diante de contextos em que o incremento e a diversificação da oferta de profissionais titulados geram incertezas quanto à `qualidade' do profissional buscado, outros parâmetros de sinalização são acionados, e o resultado é que o desenho do perfil dos candidatos torna-se cada vez mais elevado, complexo e detalhado, tanto no que diz respeito à formação educacional, mas também no que se refere ao tipo e natureza da trajetória profissional, à posse de conhecimentos específicos e de determinadas capacidades e competências.

    Full Text Available The narratives of the conquest of Portuguese America used to inform about the main characteristics of the tropical nature and to describe the habits and customs of the Amerindian peoples. In particular, in the information about the Brazilian fauna there appeared the description of a hybrid being, both extraordinary and hostile, called Ipupiara. This monster was in fact a Tupi myth. However, the examination of texts on the Ipupiara allows to distinguish narrative patterns that are significant of different attitudes with regard to the Lusitan conquest. In most texts, the more involved the narrator was in the colonial project, the greater tendency he had to naturalize the Ipupiara, considering it a real inhabitant of the Brazilian rivers.

    As narrativas da conquista da América Portuguesa notabilizaram-se pelo registro das características fundamentais da natureza tropical e pelas descrições dos hábitos e dos costumes dos povos ameríndios. Em particular, repete-se nas descrições da fauna brasílica o registro de um ser híbrido, hostil e extraordinário, o Ipupiara. O monstro na verdade não passava de um mito Tupi. Porém, o exame dos textos sobre o Ipupiara permitem distingüir padrões narrativos que podem servir de marcadores das diversas atitudes com relação ao empreendimento conquistador lusitano. Na maior parte dos textos, quanto mais comprometido o narrador com o projeto colonial, mais forte a tendencia a naturalizar o Ipupiara, a considerá-lo um ser real dos rios do Brasil.

Los avances en la industria y, en concreto la sociedad de la información, disponen de activos intangibles que son de aplicación en el mundo de los negocios.El reconocimiento de los activos intangibles en los libros de las entidades puede ser el siguiente paso, en concreto en lo que se refiere a ciertos tipos de negocios, como el de la industria del conocimiento.En el presente estudio se analizan los factores que influyen en la divulgación e información de activos intangibles voluntarios y obligatorios de un número de empresas portuguesas que cotizan en bolsa. Asimismo, exploramos la línea de pensamiento actual sobre activos intangibles y cómo se evalúan, reconocen y presentan estos recursos en los estados financieros de las empresas portuguesas.Today, as intangible assets recognized by the accounting, we can list the patents, trademarks, copyrights, etc. But there are other intangible assets whose existence is widely acknowledged that although they have not yet been identified or measured, also contribute to the results of an entity such as Goodwill or the Intellectual Capital, among others.Accounting for intangible assets gained prominence in the past decades due to changes that are occurring in the business world. The industrial revolution and, in particular, the information society, have the resources in front of the intangible world of business.The recognition of intangible assets on the books of the entities can be the next step forward especially for certain types of business such as the industry of knowledge. In this study we analyze the factors influencing the disclosure and information, mandatory and voluntary (intangible assets, of a number of Portuguese companies whose securities are traded on stock exchange. We also explore the current state of thinking on intangible assets and how those resources are being evaluated, recognized and presented in financial statements of Portuguese companies.

Assim, foram apresentados os principais aspectos conceituais e metodológicos e as diferenças existentes na construção e nos resultados obtidos pelas duas séries do SCN. Para avaliar os novos resultados, eles foram comparados com os dados de outras bases estatísticas freqüentemente utilizadas nos estudos relativos ao mercado de trabalho: PNAD, POF e Rais. O confronto dos resultados do SCN com os das bases selecionadas ratificaram a conclusão de que essas variáveis estão mais bem mensuradas na nova série do SCN, e que se encontravam subestimadas nos anos finais da série antiga.The objective of this article is to compare the results of labour factor and its associated income between the previous and the new series of the Brazilian SCN. Therefore, the main conceptual and methodological aspects and the existing differences in development and in the results of the two SCN series were presented. To evaluate the new results, they were compared to other statistical databases usually referred to in most labour market studies. The SCN results compared to PNAD, POF and Rais proved that these variables are more reliable in the new SCN series and that they were subestimated in the last years of the previous series.

    Full Text Available Os neoclássicos defendem que o mercado garante o equilíbrio entre a disponibilidade e a demanda das águas e que a cobrança altera o comportamento dos agentes para melhor. Os objetivos do artigo são discutir os limites dessa abordagem, apresentar alguns resultados internacionais assim como discutir o conceito de campo, proposto por Fligstein (2001 e Bourdieu (1990, que rompe com esta lógica predominante e se mostra como uma análise alternativa da implantação dos comitês de bacia hidrográfica. Nessa perspectiva teórica, o campo é constituído por relações de força ou poderes entre os agentes participantes e, conseqüentemente, os preços são resultados de negociações e dinâmicas sociais existentes nos comitês e não de mecanismos de mercado. A utilização da teoria dos campos permite apontar e entender que as negociações podem resultar em avanços e retrocessos.Abstract The neoclassical approach defend that the market guarantees the balance between supply and demand of water and that their payment or taxation can improve the change of behavior of agents for better. The aims of the present article are to discuss the limits of this approach, show some international results and discuss the concept of “field”, proposed by Fligstein (2001 and Bourdieu (1990 e 2001, which breaks up with the predominant theory and showed as an alternative of approach of the implementation of river basin committees. The approach of the field consists the relationship of power between the players/agents and, consequently, the prices are the result of negotiations and social dynamics that are present in the committees of water, and not result of the market mechanisms. The use of theory of field lets to understand that the negotiations can lead to breakthroughs and setbacks.

Diálogos com o pensamento filosófico serão realizados a respeito da fronteira, como lugar onde a naturalização da igualdade é posta por terra; naturalização na qual o conceito de identidade aparece como uma peça monolítica coesa e impenetrável. Defendemos o contrário: que a identidade é efeito de um processo constante, e sempre inacabado, de transformação subjetiva, pela mescla, pela angústia de não ser UM consigo mesmo e nem em relação aos outros. Apostamos, portanto, no universo múltiplo e incalculável do processo identitário, que torna único cada sujeito em seus dilemas.The aim of the present paper is to bring about a reflection on the uneasiness of two children, Alicia and João, regarding their nationalities, that is, on their ambiguous feeling of belonging regarding their own identities. Dialogues based on philosophical thinking will be carried out about the frontier as a place where the naturalization of equality is extinguished, and naturalization, in which identity is perceived as a cohesive and impenetrable monolithic piece. The opposite is actually what we stand up for: identity is the effect of a never-ending, always unfinished process of subjective transformation, through miscellany, through anguish for not being ONE with oneself or with others. In short, we believe in the multiple and immeasurable universe of the identity process, which makes every subject unique concerning his or her dilemmas.

    The DAMOCLES network is a Spanish thematic network, started in 2004, whose main objective is the establishment of a link among the different groups that perform research on atmospheric aerosols in Spain. Under the DAMOCLES coordination, a field campaign was held in summer 2006 at the INTA installations (El Arenosillo, Huelva) for the intercomparison of different kind of instruments devoted to in - situ and columnar aerosol measurement. During this field campaign, two daily meteorological soundings were carried out at noon and midnight for characterization of the atmospheric condition. A plane was also flown by the National Institute of Aerospace Technology (INTA) to carry airborne sensors for measuring different atmospheric factors: meteorological parameters, ozone with a 2BTech analyzer, and aerosol particle size distributions in the range (0.01-2) microns, by using a PCASP probe. The columnar aerosol properties were measured by seven CIMEL CE318 sun photometers. For in situ aerosol characterization, high volume collectors (DIGITEL and MCV) with DIGITEL for PM10, PM2.5 and PM1 measurement were used, with two cascade impactors for particulate matter measurement in 7 -8 granulometric fractions. For the PM10, PM2.5 and PM1 measurement, quartz fibre filters of 150 mm diameter were adapted. Other in situ deployed instruments were a Scanning Mobility Particle Sizer (SMPS, Model 3936), two Aerodynamic Particle Sizer (APS Model 3321) and one Grimm Spectrometer (Model #190). For characterization of the aerosol scattering at ground level, three integrating nephelometers TSI-3563 were used. For the columnar profiling we deployed five LIDAR instruments. In this study we have related the columnar aerosol measurements retrieved with one CE318 sun photometer to the surface PM measurements, mainly in some interesting situations where nearby pollution sources were influencing the local atmosphere. For the sun photometric analysis, we have applied the EuroSkyRad package (ESR

    Full Text Available Objetivo: Caracterizar colectivos de inmigrantes trabajadores en España y conocer sus condiciones de salud laboral mediante informantes clave. Método: Estudio cualitativo exploratorio-descriptivo con entrevistas en profundidad realizado en 2006. Se identificaron organizaciones, asociaciones y colectivos relacionados con la población inmigrante en Alicante, Barcelona, Huelva, Madrid y Valencia, y se seleccionaron los más accesibles y representativos. Se entrevistó a 43 informantes clave procedentes de 34 asociaciones u organismos. Se realizó un análisis narrativo del contenido. Resultados: Se señalan dificultades para el reconocimiento de los daños a la salud derivados del trabajo por las situaciones de irregularidad y precariedad, por resistencia por parte de los contratadores o las entidades aseguradoras, y por desconocimiento de los inmigrantes. Los informantes coinciden en que los riesgos laborales en los inmigrantes no difieren de los riesgos de los trabajadores autóctonos en similares circunstancias, pero los inmigrantes padecerían exposiciones más frecuentes e intensas por el acceso mayoritario a puestos menos cualificados y por la necesidad de prolongar las jornadas de trabajo. También se destaca su desconocimiento general en relación con los derechos de protección y de salud en el trabajo, aunque algunos informantes detectan un crecimiento de su actividad reivindicativa a través de los sindicatos. Conclusiones: Este primer acercamiento ha permitido definir algunos condicionantes generales que influirán en la salud laboral de los inmigrantes.

    Measurements of the ambient aerosol were performed at the Southern coast of Spain, within the framework of the DOMINO (Diel Oxidant Mechanisms In relation to Nitrogen Oxides) project. The field campaign took place from 20 November until 9 December 2008 at the atmospheric research station "El Arenosillo" (37°5'47.76" N, 6°44'6.94" W). As the monitoring station is located at the interface between a natural park, industrial cities (Huelva, Seville) and the Atlantic Ocean a variety of physical and chemical parameters of aerosols and gas phase could be characterized in dependency on the origin of air masses. Backwards trajectories were examined and compared with local meteorology to classify characteristic air mass types for several source regions. Aerosol number and mass as well as polycyclic aromatic hydrocarbons and black carbon concentrations were measured in PM1 and size distributions were registered covering a size range from 7 nm up to 32 μm. The chemical composition of the non-refractory submicron aerosol was measured by means of an Aerosol Mass Spectrometer (Aerodyne HR-ToF-AMS). Gas phase analyzers monitored various trace gases (O3, SO2, NO, NO2, CO2) and a weather station provided meteorological parameters. Lowest average submicron particle mass and number concentrations were found in air masses arriving from the Atlantic Ocean with values around 2 μg m-3 and 1000 cm-3. These mass concentrations were about two to four times lower than the values recorded in air masses of continental and urban origins. For some species PM1-fractions in marine air were significantly larger than in air masses originating from Huelva, a closely located city with extensive industrial activities. The largest fraction of sulfate (54%) was detected in marine air masses and was to a high degree not neutralized. In addition small concentrations of methanesulfonic acid (MSA), a product of biogenic dimethyl sulfate (DMS) emissions could be identified in the particle phase. In all

    Highlights: • Variability of radon exhalation rates from PG piles has been studied using numerical simulation supported by experimental data. • Most relevant parameters controlling the exhalation rate are radon potential and moisture saturation. • Piling up the waste increasing the height instead of the surface allows the reduction of the exhalation rate. • A proposed cover here is expected to allow exhalation rates reductions up to 95%. - Abstract: Nearly 1.0 × 10{sup 8} tonnes of phosphogypsum were accumulated during last 50 years on a 1200 ha disposal site near Huelva town (SW of Spain). Previous measurements of exhalation rates offered very variable values, in such a way that a worst case scenario could not be established. Here, new experimental data coupled to numerical simulations show that increasing the moisture contents or the temperature reduces the exhalation rate whilst increasing the radon potential or porosity has the contrary effect. Once the relative effects are compared, it can be drawn that the most relevant parameters controlling the exhalation rate are radon potential (product of emanation factor by {sup 226}Ra concentration) and moisture saturation of PG. From wastes management point of view, it can be concluded that piling up the waste increasing the height instead of the surface allows the reduction of the exhalation rate. Furthermore, a proposed cover here is expected to allow exhalation rates reductions up to 95%. We established that the worst case scenario corresponds to a situation of extremely dry winter. Under these conditions, the radon exhalation rate (0.508 Bq m{sup −2} s{sup −1}) would be below though close to the upper limit established by U.S.E.P.A. for inactive phopsphogypsum piles (0.722 Bq m{sup −2} s{sup −1})

    Full Text Available Monitoring mine waste from sulfide deposits by hyperspectral remote sensing can be used to predict surface water quality by quantitatively estimating acid drainage and metal contamination on a yearly basis. In addition, analysis of the mineralogy of surface crusts rich in soluble salts can provide a record of annual humidity and temperature. In fact, temporal monitoring of salt efflorescence from mine wastes at a mine site in the Iberian Pyrite Belt (Huelva, Spain has been achieved using hyperspectral airborne Hymap data. Furthermore, climate variability estimates are possible based on oxidation stages derived from well-known sequences of minerals, by tracing sulfide oxidation intensity using archive spectral libraries. Thus, airborne and spaceborne hyperspectral remote sensing data can be used to provide a short-term record of climate change, and represent a useful set of tools for assessing environmental geoindicators in semi-arid areas. Spectral and geomorphological indicators can be monitored on a regular basis through image processing, supported by field and laboratory spectral data. In fact, hyperspectral image analysis is one of the methods selected by the Joint Research Centre of the European Community (Ispra, Italy to study abandoned mine sites, in order to assess the enforcement of the European Mine Waste Directive (2006/21/EC of the European Parliament and of the Council 15 March 2006 on the management of waste from extractive industries (Official Journal of the European Union, 11 April 2006. The pyrite belt in Andalucia has been selected as one of the core mission test sites for the PECOMINES II program (Cracow, November 2005, using imaging spectroscopy; and this technique is expected to be implemented as a monitoring tool by the Environmental Net of Andalucía (REDIAM, Junta de Andalucía, Spain.

    This study explores the environmental impact of metal exposure on humans through detailed phase and structural characterization of gallstones from two environmentally contrasting populations in Huelva Province (SW Spain). A total of 42 gallstone samples, obtained after surgical intervention at the Riotinto Hospital, were studied by powder X-ray diffraction (XRD), Fourier Transformed Infra-Red spectroscopy (FTIR), FTIR-μ-ATR (Attenuated Total Reflection) coupled with an optical microscope, and by Environmental Scanning Electron Microscope with Energy Dispersive X-ray Spectroscopy (ESEM-EDS), and subsequently classified according to their phase composition and structure. Additionally, the patients were enquired for their living habits in order to analyze the source of possible exposure to metal contamination. The gallstones were classified into pure, mixed and composite cholesterol stones, black and brown pigment stones, and carbonate stones. The patients from the study group residing in a region with acknowledged metal contamination of both natural and anthropogenic origin have a higher risk of metal exposure through contaminated soil, particle matter in the air, and consumption of local water and food products. According to our findings, the metal exposure is related to a higher tendency of forming black pigment stones in the study group in comparison to the control group residing in a natural park with nearly pristine environmental conditions. Moreover, the gallstones from the study group showed to contain more abundant metal components, such as Cu, Fe, Ni, and Zn, than those from the control group. To our knowledge this is the first study to examine the regional environmental impact of metal exposure on human gallstones. Copyright © 2016 Elsevier B.V. All rights reserved.

    Highlights: Black-Right-Pointing-Pointer Phosphogypsum wastes are proposed to reduce CO{sub 2} greenhouse gas emissions. Black-Right-Pointing-Pointer Phosphogypsum dissolution with NaOH results in Ca(OH){sub 2} precipitation and Na{sub 2}SO{sub 4}. Black-Right-Pointing-Pointer Aqueous carbonation of Ca(OH){sub 2} with CO{sub 2} results in the CaCO{sub 3} precipitation. Black-Right-Pointing-Pointer Metals contained in the phosphogypsum are transferred to the final calcite. Black-Right-Pointing-Pointer Applications of CaCO{sub 3} and Na{sub 2}SiO{sub 4} by-products are proposed to improve viability. - Abstract: Industrial wet phosphoric acid production in Huelva (SW Spain) has led to the controversial stockpiling of waste phosphogypsum by-products, resulting in the release of significant quantities of toxic impurities in salt marshes in the Tinto river estuary. In the framework of the fight against global climate change and the effort to reduce carbon dioxide emissions, a simple and efficient procedure for CO{sub 2} mineral sequestration is presented in this work, using phosphogypsum waste as a calcium source. Our results demonstrate the high efficiency of portlandite precipitation by phosphogypsum dissolution using an alkaline soda solution. Carbonation experiments performed at ambient pressure and temperature resulted in total conversion of the portlandite into carbonate. The fate of trace elements present in the phosphogypsum waste was also investigated, and trace impurities were found to be completely transferred to the final calcite. We believe that the procedure proposed here should be considered not only as a solution for reducing old stockpiles of phosphogypsum wastes, but also for future phosphoric acid and other gypsum-producing industrial processes, resulting in more sustainable production.

    In 2005 the Department held a steady course. Topics of nuclear physics, atomic physics and materials research that started in previous years were continued. Although our team was smaller than years ago, the scientific activity, estimated by number of published papers is still very high. Scientists of the Department are co-authors or authors of more than 50 papers. Nuclear physics, which is our main-stream activity, covered a wide energy range. It started close to the Coulomb barrier, where 6 He breakup on heavy nuclei were studied, and ended at zones of tens of GeV; such high energies were used to investigate spin structure of deuterons and to explore hadron leptoproduction. Traditionally, experimental investigations in the fields of atomic physics and of physics of materials completed the scene. Our old Van de Graaff accelerator Lech was used for studies of M-shell ionisation of heavy elements, for hardening of Ultra-High Molecular Weight Polyethylene and for characterisation of materials with RBS and NRA techniques. The VdG runs perfectly although it is over 40 years old. Two Ph.D. students finished their theses and were promoted. Izabela Fijal's work concerned multi-ionization and intrashell coupling effects for L-shell x-ray emission induced by heavy ions, while Sergiy Mezhevych showed studies on scattering of 11 B from carbon isotopes. It is obvious that contemporary works on physics do not arise in a single lab. Our contributions to many papers were possible due owing to collaborations involving many institutions. Some of them are listed: GSI, Darmstadt (PANDA Collaboration) DESY, Hamburg (HERMES Collaboration) Institut fuer Kernphysik, Forschungszentrum Juelich Forschungszentrum Rossendorf CSNSM, Orsay GANIL, Caen University of Huelva Institute of Nuclear Research, Kiev SLCJ, Warsaw ITME, Warsaw Some of our colleagues traditionally gave lectures and made physical demonstrations on Warsaw informal learning events: 9 th Science Picnic and 9 th Science Festival

    Cool roofs are an inexpensive method to save energy and to improve the comfort level in buildings in mild and hot climates. A high scale implementation of cool roofs in Andalusia, in the south of Spain, could potentially save 295,000 kWh per year, considering only residential buildings with flat roofs using electrical heating. At the current energy prices, consumers can save 59 million euros annually in electricity costs and the emission of 136,000 metric tons of CO 2 can be directly avoided every year from the production of that electricity. If radiative forcings are considered, Andalucía can potentially offset between 9.44 and 12 Mt of CO 2 . All the provinces in the rest of Spain are also studied in this paper. The biggest savings are achieved in Gran Canaria (48%), Tenerife (48%), Cádiz (36%), Murcia (33%), Huelva (30%), Málaga (29%), Almería (29%) and Sevilla (28%), where savings are greater than 2 euros per square meter of flat roof for old buildings with dark roofs. For the biggest cities the range of savings obtained are: between 7.4% and 11% in Madrid, between 12% and 18% in Barcelona and between 14% and 20% in Valencia. -- Highlights: ► We estimate potential savings in energy, CO 2 , and money for cool roofs in Spain (residential sector with flat roofs). ► Average savings are of around one euro per square meter in the biggest cities. ► Potential savings are of more than 2 €/m 2 in the hottest cities. ► In Andalusia the potential savings are 300 MWh, 60 millions euro and 136,000 tons of CO 2 per year. ► With forcings, the CO 2 equivalence of cool roofs in Andalusia is between 9 and 12 Mt.

    The physical and chemical characteristics of radon gas make it a good tracer for use in the application of atmospheric transport models. For this purpose the radon source needs to be known on a global scale and this is difficult to achieve by only direct experimental methods. However, indirect methods can provide radon flux maps on larger scales, but their reliability has to be carefully checked. It is the aim of this work to compare radon flux values obtained by direct and indirect methods in a measurement campaign performed in the summer of 2008. Different systems to directly measure radon flux from the soil surface and to measure the related parameters terrestrial γ dose and 226 Ra activity in soil, for indirect estimation of radon flux, were tested. Four eastern Spanish sites with different geological and soil characteristics were selected: Teruel, Los Pedrones, Quintanar de la Orden and Madrid. The study shows the usefulness of both direct and indirect methods for obtaining radon flux data. Direct radon flux measurements by continuous and integrated monitors showed a coefficient of variation between 10% and 23%. At the same time, indirect methods based on correlations between 222 Rn and terrestrial γ dose rate, or 226 Ra activity in soil, provided results similar to the direct measurements, when these proxies were directly measured at the site. Larger discrepancies were found when proxy values were extracted from existing data bases. The participating members involved in the campaign study were the Institute of Energy Technology (INTE) of the Technical University of Catalonia (UPC), Huelva University (UHU), and Basel University (BASEL).

    Discrimination is an important determinant of health inequalities, and immigrants may be more vulnerable to certain types of discrimination than the native-born. This study analyses the relationship between immigrants' perceived discrimination and various self-reported health indicators. A cross-sectional survey was conducted (2008) amongst a non-random sample of 2434 immigrants from Ecuador, Morocco, Romania and Colombia in four Spanish cities: Barcelona, Huelva, Madrid and Valencia. A factorial analysis of variables revealed three dimensions of perceived discrimination (due to immigrant status, due to physical appearance, and workplace-related). The association of these dimensions with self-rated health, mental health (GHQ-12), change in self-rated health between origin and host country, and other self-reported health outcomes was analysed. Logistic regression was used adjusting for potential confounders (aOR-95%CI). Subjects with worsening self-reported health status potentially attributable to perceived discrimination was estimated (population attributable proportion, PAP %). 73.3% of men and 69.3% of women immigrants reported discrimination due to immigrant status. Moroccans showed the highest prevalence of perceived discrimination. Immigrants reporting discrimination were at significantly higher risk of reporting health problems than those not reporting discrimination. Workplace-related discrimination was associated with poor mental health (aOR 2.97 95%CI 2.45-3.60), and the worsening of self-rated health (aOR 2.20 95%CI 1.73- 2.80). 40% (95% CI 24-53) PAP of those reporting worse self-rated health could be attributable to discrimination due to immigrant status. Discrimination may constitute a risk factor for health in immigrant workers in Spain and could explain some health inequalities among immigrant populations in Spanish society.

    Nighttime mixing ratios of boundary layer N2O5 were determined using cavity-ring-down spectroscopy during the DOMINO campaign in Southern Spain (Diel Oxidant Mechanisms In relation to Nitrogen Oxides, 21 November 2008-8 December 2008). N2O5 mixing ratios ranged from below the detection limit (~5 ppt) to ~500 ppt. A steady-state analysis constrained by measured mixing ratios of N2O5, NO2 and O3 was used to derive NO3 lifetimes and compare them to calculated rates of loss via gas-phase and heterogeneous reactions of both NO3 and N2O5. Three distinct types of air masses were encountered, which were largely marine (Atlantic), continental or urban-industrial in origin. NO3 lifetimes were longest in the Atlantic sector (up to ~30 min) but were very short (a few seconds) in polluted, air masses from the local city and petroleum-related industrial complex of Huelva. Air from the continental sector was an intermediate case. The high reactivity to NO3 of the urban air mass was not accounted for by gas-phase and heterogeneous reactions, rates of which were constrained by measurements of NO, volatile organic species and aerosol surface area. In general, high NO2 mixing ratios were associated with low NO3 lifetimes, though heterogeneous processes (e.g. reaction of N2O5 on aerosol) were generally less important than direct gas-phase losses of NO3. The presence of SO2 at levels above ~2 ppb in the urban air sector was always associated with very low N2O5 mixing ratios indicating either very short NO3 lifetimes in the presence of combustion-related emissions or an important role for reduced sulphur species in urban, nighttime chemistry. High production rates coupled with low lifetimes of NO3 imply an important contribution of nighttime chemistry to removal of both NOx and VOC.

    The activities of the phosphate industry may lead to enhanced levels of naturally occurring radioactivity in terrestrial and aquatic ecosystems. We performed a preliminary environmental risk assessment (ERA) of environmental contamination resulting from the activities of 5 phosphate fertiliser plants (located in Belgium, Spain, Syria, Egypt, Brazil), a phosphate-mine and a phosphate-export platform in a harbour (both located in Syria). These sites were selected because of the availability of information on concentrations of naturally occurring radionuclides in the surrounding environments. Assessments were generally performed considering highest environmental concentrations reported in the studies. The ERICA Tool, operating in a Tier 2 assessment mode, was used to predict radiation dose rates and associated risk to the selected reference organisms using the ERICA default parameter setting. Reference organisms were those assigned as default by the ERICA Tool. Potential impact is expressed as a best estimate risk quotient (RQ) based on a radiation screening value of 10 μGy h −1 . If RQ ≤ 1, the environment is considered unlikely to be at risk and further radiological assessment is not deemed necessary. Except for one of the cases assessed, the best estimate RQ exceeded 1 for at least one of the reference organisms. Internal exposure covered for 90–100 % of the total dose. 226 Ra or 210 Po were generally the highest contributors to the dose. The aquatic ecosystems in the vicinity of the phosphate fertiliser plants in Tessenderlo (Belgium), Huelva (Spain), Goiás (Brazil) and the terrestrial environment around the phosphate mine in Palmyra (Syria) are the ecosystems predicted to be potentially most at risk. - Highlights: • The adjusted highlights Environmental radionuclide enrichment from P-industry warrants risk assessment. • 226 Ra and 210 Po are the most dose contributing radionuclides. • The total dose rate is strongly driven by the internal

    This paper comparatively shows the influence of four water treatment processes on the formation of trihalomethanes (THMs) in a water distribution system. The study was performed from February 2005 to January 2012 with analytical data of 600 samples taken in Aljaraque water treatment plant (WTP) and 16 locations along the water distribution system (WDS) in the region of Andévalo and the coast of Huelva (southwest Spain), a region with significant seasonal and population changes. The comparison of results in the four different processes studied indicated a clear link of the treatment process with the formation of THM along the WDS. The most effective treatment process is preozonation and activated carbon filtration (P3), which is also the most stable under summer temperatures. Experiments also show low levels of THMs with the conventional process of preoxidation with potassium permanganate (P4), delaying the chlorination to the end of the WTP; however, this simple and economical treatment process is less effective and less stable than P3. In this study, strong seasonal variations were obtained (increase of THM from winter to summer of 1.17 to 1.85 times) and a strong spatial variation (1.1 to 1.7 times from WTP to end points of WDS) which largely depends on the treatment process applied. There was also a strong correlation between THM levels and water temperature, contact time and pH. On the other hand, it was found that THM formation is not proportional to the applied chlorine dose in the treatment process, but there is a direct relationship with the accumulated dose of chlorine. Finally, predictive models based on multiple linear regressions are proposed for each treatment process.

    The Spanish capacity for phosphoric acid production is 500.000 t P 2 O 5 /yr. This acid has an average concentration of 365 g U 3 O 8 / t P 2 O 5 . Therefore about 180 t U 3 O 8 /yr are dissolved. In 1969, the Junta de Energia Nuclear (JEN) developed, in bench scale, a solvent extraction process to recover the uranium from the phosphoric acid. The solvent used was a synergistic mixture of D2EHPA and TOPO. The results were very promising with good recovery and very high quality for the uranium concentrate. Later, the J.E.N. continued the studies in a pilot plant scale. For this purpose, was built an experimental facility in Huelva; it can treat about 7 cu. m/day of brown acid. Fosforico Espanol, S.A. (FESA) collaborated in the studies and agreed to setting up these installations in their factory. They also provided fresh phosphoric acid for the tests. In this pilot plant we studied the following stages: a) Clarification and conditioning of the phosphoric acid; b) Uranium extraction followed by stripping in a reducing medium; c) Purification by extraction and washing; d) Obtention of the concentrate by stripping with ammonia and CO 2 gas, followed by crystallization of the ammonium uranyl tricarbonate (AUT); and e) Calcination of the concentrate to decompose the AUT to uranium oxides. The results confirmed the laboratory test data. Recuperation levels were between 85 and 90%. The AUT calcined at 550 0 C. gave a product with 96-98% U 3 O 8 . In view of the pilot plant results we have prepared a black book for an industrial plant to treat about 3700 cu. m/day of phosphoric acid. At the present time the financial aspects of this installation are being studied [es

We believe that the procedure proposed here should be considered not only as a solution for reducing old stockpiles of phosphogypsum wastes, but also for future phosphoric acid and other gypsum-producing industrial processes, resulting in more sustainable production.

    Full text: IAEA has included phosphate production among twelve NORM industries identified for scrutiny and possible regulation. 'Wet' production results in 1) phosphoric acid, as phosphate essential for world-wide food production; and 2) phosphogypsum (PG), which in some countries is used in both agriculture and construction. Phosphate deposits contain 238 U and 232 Th and their decay products; some have sufficient U content for commercial recovery. This puts the industry within the scope of the IAEA Fundamental Safety Principles, and of the International Basic Safety Standards (BSS). Phosphogypsum is a test case for defining and managing NORM industry residues and wastes as typical activity concentrations are extremely low but worldwide stockpiles amount to billions of tonnes. In some jurisdictions, phosphogypsum is regulated as a hazardous, radioactive waste rather than as a resource - with costly results. The phosphate industry is undergoing its most profound change since World War II, led by surging demand from Brazil, Russia, India and China, Established production centres, such as Morocco, are increasing capacity; major new facilities are being built, such as Ma'aden, Saudi Arabia. In consequence, many local jurisdictions face unfamiliar challenges and seek guidance on how to proceed. New research both on phosphate and phosphogypsum has significantly changed our understanding of the domain. A five year study of phosphogypsum use in Huelva, Spain, presents a model of a coherent, evidence-based approach, grounded in sound policy, good science and best practices. The 'constructive regulation' approach builds directly on evidence and lessons learned from a long, continuous tradition of PG use in Spain, Brazil and the United States. It draws on the results of the Stack Free by '53? project to modify John Nash's cooperative game and bargaining theory as a basis for defining a new sustainable point of equilibrium in which phosphogypsum production and consumption are

    Full Text Available Abstract Background Spain shows the highest bladder cancer incidence rates in men among European countries. The most important risk factors are tobacco smoking and occupational exposure to a range of different chemical substances, such as aromatic amines. Methods This paper describes the municipal distribution of bladder cancer mortality and attempts to "adjust" this spatial pattern for the prevalence of smokers, using the autoregressive spatial model proposed by Besag, York and Molliè, with relative risk of lung cancer mortality as a surrogate. Results It has been possible to compile and ascertain the posterior distribution of relative risk for bladder cancer adjusted for lung cancer mortality, on the basis of a single Bayesian spatial model covering all of Spain's 8077 towns. Maps were plotted depicting smoothed relative risk (RR estimates, and the distribution of the posterior probability of RR>1 by sex. Towns that registered the highest relative risks for both sexes were mostly located in the Provinces of Cadiz, Seville, Huelva, Barcelona and Almería. The highest-risk area in Barcelona Province corresponded to very specific municipal areas in the Bages district, e.g., Suría, Sallent, Balsareny, Manresa and Cardona. Conclusion Mining/industrial pollution and the risk entailed in certain occupational exposures could in part be dictating the pattern of municipal bladder cancer mortality in Spain. Population exposure to arsenic is a matter that calls for attention. It would be of great interest if the relationship between the chemical quality of drinking water and the frequency of bladder cancer could be studied.

    One of the most important social phenomena in the global context is the flow of immigration from developing countries, motivated by economic and employment related issues. Discrimination can be approached as a health risk factor within the immigrant population's working environment, especially for those immigrants at greater risk from social exclusion and marginalisation. The aim of this study is to research perceptions of discrimination and the specific relationship between discrimination in the workplace and health among Spain's immigrant population. A qualitative study was performed by means of 84 interviews and 12 focus groups held with immigrant workers in five cities in Spain receiving a large influx of immigrants (Madrid, Barcelona, Valencia, Alicante and Huelva), covering representative immigrant communities in Spain (Romanians, Moroccans, Ecuadorians, Colombians and Sub-Saharan Africans). Discourse narrative content analysis was performed using pre-established categories and gradually incorporating other emerging categories from the immigrant interviewees themselves. The participants reported instances of discrimination in their community and working life, characterised by experiences of racism, mistreatment and precarious working conditions in comparison to the Spanish-born population. They also talked about limitations in terms of accessible occupations (mainly construction, the hotel and restaurant trade, domestic service and agriculture), and described major difficulties accessing other types of work (for example public administration). They also identified political and legal structural barriers related with social institutions. Experiences of discrimination can affect their mental health and are decisive factors regarding access to healthcare services. Our results suggest the need to adopt integration policies in both the countries of origin and the host country, to acknowledge labour and social rights, and to conduct further research into individual

    Four alternatives (runs A, B, C and D) for heavy metals removal (Fe, Cu, Zn and Al) from acid mine drainage water (AMDW) produced in the mining areas of the Huelva Province, Spain, were evaluated. In run A, the anaerobic effluent from the treatment of acid mine drainage water (cheese whey added as a source of carbon) was mixed with the raw AMDW. The pH increased to 3.5 with the addition of KOH. In run B, biogas with around 30% of hydrogen sulphide obtained in the anaerobic reactor was sparged to the mixture obtained in run A, but in this case at a pH of 5.5. In run C, the pH of the raw AMDW was increased to 3.5 by the addition of KOH solution. Finally, in run D, the pH of the raw AMDW was increased to 5.5 by the addition of KOH solution and further biogas was sparged under the same conditions as in run A. It was found that heavy metal removal was a function of pH. At a pH of 3.5 most of the iron was removed while Zn and Cu were partially removed. At a pH of 5.5 the removal of all metals increased considerably. The best results were obtained in run B where the percentages of removal of Fe, Cu, Zn and Al achieved values of 91.3, 96.1, 79.0 and 99.0%, respectively. According to the experimental results obtained tentative schemas of the flow diagram of the processes were proposed.

    Full Text Available Nighttime mixing ratios of boundary layer N2O5 were determined using cavity-ring-down spectroscopy during the DOMINO campaign in Southern Spain (Diel Oxidant Mechanisms In relation to Nitrogen Oxides, 21 November 2008–8 December 2008. N2O5 mixing ratios ranged from below the detection limit (~5 ppt to ~500 ppt. A steady-state analysis constrained by measured mixing ratios of N2O5, NO2 and O3 was used to derive NO3 lifetimes and compare them to calculated rates of loss via gas-phase and heterogeneous reactions of both NO3 and N2O5. Three distinct types of air masses were encountered, which were largely marine (Atlantic, continental or urban-industrial in origin. NO3 lifetimes were longest in the Atlantic sector (up to ~30 min but were very short (a few seconds in polluted, air masses from the local city and petroleum-related industrial complex of Huelva. Air from the continental sector was an intermediate case. The high reactivity to NO3 of the urban air mass was not accounted for by gas-phase and heterogeneous reactions, rates of which were constrained by measurements of NO, volatile organic species and aerosol surface area. In general, high NO2 mixing ratios were associated with low NO3 lifetimes, though heterogeneous processes (e.g. reaction of N2O5 on aerosol were generally less important than direct gas-phase losses of NO3. The presence of SO2 at levels above ~2 ppb in the urban air sector was always associated with very low N2O5 mixing ratios indicating either very short NO3 lifetimes in the presence of combustion-related emissions or an important role for reduced sulphur species in urban, nighttime chemistry. High production rates coupled with low lifetimes of NO3 imply an important contribution of nighttime chemistry to removal of both NOx and VOC.

    To explore the association between gender-role attitudes and the recognition of abuse among adolescents and young adults during dating relationships. Cross-correlation study. 57 schools of secondary education, vocational education and university in five provinces of Spain (Huelva, Seville, A Coruña, Pontevedra and Asturias). 4,337 students aged between 15 and 26 years (40.6% males and 59.4% female) who had a dating relationship that lasted more than a month. The Gender Role Attitudes Scale was used, which consists of 20 indicators of egalitarian or sexism attitudes at the family, social and occupational level. The students also reported whether they suffered from recognized abuse (RA), unperceived abuse (UPA), or not abused (NA). In the whole sample, 68.6% declared themselves NA, 26.4% were under a situation of UPA, and 5.0% were RA. The RA group was more frequent among the females (6.3%), ≥18 years (6.4%) and university students (6.9%). UPA was more common in males (30.2%). The most sexist attitudes were found in the occupational dimension and especially in men and adolescents (15-17 years). Less sexist attitudes were associated with a lower probability of experiencing UPA (odds ratio=.71; P-trend<.001). Sexism seems to hinder the recognition of abuse. Achieving gender equity in adolescence and youth is imperative. Public health efforts should focus on men, as they constitute the group with more sexist attitudes and with higher prevalence of UPA.

    Four pink-pigmented, non-motile, Gram-staining-negative and moderately halophilic curved rods, designated strains SSL50T, SSL25, SSL97 and SSL4, were isolated from a saltern located in Isla Cristina, Huelva, south-west Spain. Phylogenetic analyses based on 16S rRNA gene sequences showed that they were members of the genus Spiribacter, most closely related to Spiribacter curvatus UAH-SP71T (99.3-99.5 % sequence similarity) and Spiribacter salinus M19-40T (96.5-96.7 %). Other related strains were Alkalilimnicola ehrlichii MLHE-1T (95.1-95.3 %), Arhodomonas recens RS91T (95.1-95.2 %) and Arhodomonas aquaeolei ATCC 49307T (95.0-95.1 %), all members of the family Ectothiorhodospiraceae. The major fatty acids were C18 : 1ω6c and/or C18 : 1ω7c, C16 : 0 and C12 : 0. The DNA G+C range was 64.0-66.3 mol%. The DNA-DNA hybridization values between strains SSL50T, SSL25, SSL97, SSL4 and S. piribacter. curvatus UAH-SP71T were 37-49 %. The average nucleotide identity (ANIb) values between the genome of strain SSL50T and those of the two other representatives of the genus Spiribacter, S. curvatus UAH-SP71T and S. salinus M19-40T, were 82.4 % and 79.1 %, respectively, supporting the proposal of a novel species of the genus Spiribacter. On the basis of the polyphasic analysis, the four new isolates are considered to represent a novel species of the genus Spiribacter, for which the name Spiribacter roseus sp. nov. is proposed. The type strain is SSL50T (=CECT 9117T=IBRC-M 11076T).

    In the frame of a research project on microscopic distribution and speciation of geogenic thallium (Tl) from contaminated mine soils, Tl-bearing pyrite ore samples from Riotinto mining district (Huelva, SW Spain) were experimentally fired to simulate a roasting process. Concentration and volatility behavior of Tl and other toxic heavy metals was determined by quantitative ICP-MS, whereas semi-quantitative mineral phase transitions were identified by in situ thermo X-Ray Diffraction (HT-XRD) and Scanning Electron Microscopy with Energy Dispersive Spectroscopy (SEM-EDS) analyses after each firing temperature. Sample with initial highest amount of quartz (higher Si content), lowest quantity of pyrite and traces of jarosite (lower S content) developed hematite and concentrated Tl (from 10 up to 72 mg kg -1 ) after roasting at 900 °C in an oxidizing atmosphere. However, samples with lower or absent quartz content and higher pyrite amount mainly developed magnetite, accumulating Tl between 400 and 500 °C and releasing Tl from 700 up to 900 °C (from 10-29 mg kg -1 down to 4-1 mg kg -1 ). These results show the varied accumulative, or volatile, behaviors of one of the most toxic elements for life and environment, in which oxidation of Tl-bearing Fe sulfides produce Fe oxides wastes with or without Tl. The initial chemistry and mineralogy of pyrite ores should be taken into account in coal-fired power stations, cement or sulfuric acid production industry involving pyrite roasting processes, and steel, brick or paint industries, which use iron ore from roasted pyrite ash, where large amounts of Tl entail significant environmental pollution.

    The Tinto and Odiel rivers in southwest Spain drain the world's largest sulfide mineral formation: the Iberian Pyrite Belt which has been worked since 2,500 BC. The Tinto and Odiel estuarine zones include both an extensive area of salt marsh and an intensively industrialized urban area. As a consequence of pyrite oxidation, the Tinto and Odiel rivers are strongly acidic (pH major and trace elements were determined in the acid mine drainage affected estuary of the Ría de Huelva. During estuarine mixing, ore-derived metal concentrations exhibit excellent correlations with pH as the main controlling parameter. As pH increases, concentrations of dissolved ore-associated elements are attenuated, and this process is enhanced during the summer months. The decrease in Fe and Al concentrations ranged from 80 to 100 % as these elements are converted from dissolved to sediment-associated forms in the estuary. Coprecipitation/adsorption processes also removed between 60 and 90 % of the originally dissolved Co, Cu, Mn, Pb, Zn, and Th; however, Cd and Ni exhibited a greater propensity to remain in solution, with an average removal of approximately 60 %. On the other hand, As and U exhibited a different behavior; it is likely that these elements remain in dissolved forms because of the formation of U carbonates and soluble As species. Concentrations of As remain at elevated levels in the outer estuary (average = 48 μg L(-1)) which exceeds concentrations present in the Tinto River. Nevertheless, the estuary has recently witnessed improvements in water quality, as compared to results of several previous studies reported in the 1990s.

    This study provides geochemical data with the aim of identifying and tracing the weathering of phosphogypsum wastes stack-piled directly on salt-marshes of the Tinto River (Estuary of Huelva, SW Spain). With that purpose, different types of highly-polluted acid solutions were collected in the stack. Connection between these solutions and the estuarine environment was studied by geochemical tracers, such as rare earth elements (REE) and their North American Shale Composite (NASC)-normalized patterns and Cl/Br ratios. Phosphogypsum-related wastewaters include process water stored on the surface, pore-water contained in the phosphogypsum profile and edge outflow water emerging from inside the stack. Edge outflow waters are produced by waterlogging at the contact between phosphogypsum and the nearly impermeable marsh surface and discharge directly into the estuary. Process water shows geochemical characteristics typical of phosphate fertilizers, i.e. REE patterns with an evident enrichment of heavy-REE (HREE) with respect to middle-REE (MREE) and light-REE (LREE). By contrast, REE patterns of deeper pore-water and edge outflows are identical to those of Tinto River estuary waters, with a clear enrichment of MREE relative to LREE and HREE denoting influence of acid mine drainage. Cl/Br ratios of these solutions are very close to that of seawater, which also supports its estuarine origin. These findings clearly show that process water is not chemically connected with edge outflows through pore-waters, as was previously believed. Phosphogypsum weathering likely occurs by an upward flow of seawater from the marsh because of overpressure and permeability differences. Several recommendations are put forward in this study to route restoration actions, such as developing treatment systems to improve the quality of the edge outflow waters before discharging to the receiving environment.

    Full Text Available El objetivo de este estudio es conocer si las relaciones de pareja en jóvenes, se ven influenciadas por el uso de las redes sociales y si dichas redes se convierten hoy en una nueva modalidad de violencia de pareja. Mediante un cuestionario compuesto de 10 ítems y la realización de grupos de discusión, en una muestra de 511 adolescentes de entre 16 y 19 años, de Huelva y Granada. Encontramos que este medio se convierte en una medida de control en las parejas y de violencia. Se procedió en un primer momento a pasar dicho cuestionario y posteriormente se realizaron 3 grupos de discusión entre los participantes. Se ha procedido a analizar los datos tanto de forma cuantitativa como cualitativa. La gran mayoría de sujetos declara no ejecutar conductas ni recibirlas como medidas de coacción, pero sí encontramos que las redes sociales se usan para intimidar, controlar a la pareja, usurpar la personalidad e incluso como violación de la intimidad tras las rupturas de pareja. Además mayoritariamente los encuestados reconocen como «normales» y esperables conductas de los chicos hacia sus parejas, dada la confianza y el amor profesado, que se definen como violencia de género en todo su sentido. Se estima necesaria una mayor formación en el uso de las redes sociales y fomentar medidas de prevención de la violencia de pareja mediante estos sistemas.

    Full Text Available El cambio en las metodologías de aula viene de la mano, en muchos casos, de Internet y de las herramientas de la Web 2.0. Por otra parte, el desarrollo de una perspectiva de corte constructivista apoyado en el trabajo en grupo, suponen que la formación de los estudiantes puede ser alimentada a través de este tipo de recursos, dado que potencia, entre otros aspectos la socialización, la búsqueda de información, el logro de una meta común, etc. La investigación que aquí se presenta versa sobre la realidad de los procesos de aprendizaje universitario con TIC y las preferencias para trabajar dentro y fuera del aula de los estudiantes de las universidades de Córdoba, Huelva, Sevilla y País Vasco. Los objetivos se centran en conocer las percepciones que los alumnos tienen sobre el software social y el trabajo en grupo y colaborativo, cuáles son las herramientas de software social que emplean y si hay diferencias en función de la universidad de procedencia. Se empleó como instrumento de recogida de datos un cuestionario conformado por cuatro dimensiones. Se concluye que el alumnado está interesado en el empleo del trabajo en grupo como metodología de aula, así como su escaso conocimiento de las herramientas tecnológicas, salvo de las redes sociales. Al mismo tiempo, estos resultados aportan un instrumento fiable para el diagnóstico de las variables que lo conforman.

    Full Text Available En este artículo se comparan y discuten los resultados obtenidos en los análisis locales de las 14 ciudades participantes en el proyecto EMECAM. Se analizan las series temporales de mortalidad, contaminantes (partículas en suspensión, SO2, NO2, O3 y CO, temperatura y otros factores, obtenidos de registros de instituciones públicas. Utilizando regresión autorregresiva de Poisson, se ha estimado la relación a corto plazo entre la mortalidad y los indicadores de contaminación atmosférica en cada una de las siguientes ciudades: Barcelona, Gran Bilbao, Cartagena, Castellón, Gijón, Huelva, Madrid, Pamplona, Sevilla, Oviedo, Valencia, Vigo, Vitoria y Zaragoza. Los resultados indican que los valores de contaminación atmosférica en nuestro país son similares a los de otras ciudades europeas. Los niveles de los distintos contaminantes apuntan hacia el tráfico rodado como la fuente principal en la mayoría de ellas. Se encuentra una asociación entre la mortalidad y diferentes contaminantes en la mayoría de ciudades, aunque los resultados no son homogéneos entre las ciudades y presentan variabilidad en las distintas causas a estudio. En algunas ciudades, especialmente en aquellas de menor población, no se encuentran unos resultados que aporten evidencias de asociación, o bien los mismos son poco consistentes. El meta-análisis proporcionará estimaciones para el conjunto de las ciudades y permitirá una evaluación más clara del efecto retardado de la contaminación sobre la mortalidad. Es de destacar la participación como investigadores activos en este proyecto de técnicos de servicios de salud pública.

  5. Enhanced Productivity of a Lutein-Enriched Novel Acidophile Microalga Grown on Urea

    Full Text Available Coccomyxa acidophila is an extremophile eukaryotic microalga isolated from the Tinto River mining area in Huelva, Spain. Coccomyxa acidophila accumulates relevant amounts of b-carotene and lutein, well-known carotenoids with many biotechnological applications, especially in food and health-related industries. The acidic culture medium (pH < 2.5 that prevents outdoor cultivation from non-desired microorganism growth is one of the main advantages of acidophile microalgae production. Conversely, acidophile microalgae growth rates are usually very low compared to common microalgae growth rates. In this work, we show that mixotrophic cultivation on urea efficiently enhances growth and productivity of an acidophile microalga up to typical values for common microalgae, therefore approaching acidophile algal production towards suitable conditions for feasible outdoor production. Algal productivity and potential for carotenoid accumulation were analyzed as a function of the nitrogen source supplied. Several nitrogen conditions were assayed: nitrogen starvation, nitrate and/or nitrite, ammonia and urea. Among them, urea clearly led to the best cell growth (~4 ´ 108 cells/mL at the end of log phase. Ammonium led to the maximum chlorophyll and carotenoid content per volume unit (220 mg·mL-1 and 35 mg·mL-1, respectively. Interestingly, no significant differences in growth rates were found in cultures grown on urea as C and N source, with respect to those cultures grown on nitrate and CO2 as nitrogen and carbon sources (control cultures. Lutein accumulated up to 3.55 mg·g-1 in the mixotrophic cultures grown on urea. In addition, algal growth in a shaded culture revealed the first evidence for an active xanthophylls cycle operative in acidophile microalgae.

    Brine shrimp, Artemia spp., act as intermediate hosts for a range of cestode species that use waterbirds as their final hosts. These parasites can have marked influences on shrimp behavior and fecundity, generating the potential for cascading effects in hypersaline food webs. We present the first comprehensive study of the temporal dynamics of cestode parasites in natural populations of brine shrimp throughout the annual cycle. Over a 12-month period, clonal Artemia parthenogenetica were sampled in the Odiel marshes in Huelva, and the sexual Artemia salina was sampled in the Salinas de Cerrillos in Almería. Throughout the year, 4–45 % of A. parthenogenetica were infected with cestodes (mean species richness = 0.26), compared to 27–72 % of A. salina (mean species richness = 0.64). Ten cestode species were recorded. Male and female A. salina showed similar levels of parasitism. The most prevalent and abundant cestodes were those infecting the most abundant final hosts, especially the Greater Flamingo Phoenicopterus ruber. In particular, the flamingo parasite Flamingolepis liguloides had a prevalence of up to 43 % in A. parthenogenetica and 63.5 % in A. salina in a given month. Although there was strong seasonal variation in prevalence, abundance, and intensity of cestode infections, seasonal changes in bird counts were weak predictors of the dynamics of cestode infections. However, infection levels of Confluaria podicipina in A. parthenogenetica were positively correlated with the number of their black-necked grebe Podiceps nigricollis hosts. Similarly, infection levels of Anomotaenia tringae and Anomotaenia microphallos in A. salina were correlated with the number of shorebird hosts present the month before. Correlated seasonal transmission structured the cestode community, leading to more multiple infections than expected by chance.

    A detailed physical and chemical characterisation of total suspended particles (TSP) in the highly industrialised city of Huelva (southwestern Spain) was carried out. The results evidenced a coarse grain-size prevalence (PM 10 accounting for only 40% of TSP mass, 37 and 91 μg/m 3 , respectively). PM 10 levels are in the usual range for urban background sites in Spain. The crustal, anthropogenic and marine components accounted for a mean of a 40%, 24% and 5% of bulk TSP, respectively. As expected from the industrial activities, relatively high PO 4 3- and As levels for an urban site were detected. In addition to the crustal and marine components, source apportionment analysis revealed three additional emission sources influencing the levels and composition of TSP: (a) a petrochemical source, (b) a mixed metallurgical-phosphate source, (c) and an unknown source (Sb and NO 3 - ). Due to the high local emissions, the mean TSP anthropogenic contribution (mostly PM 10 ) obtained for all possible air mass transport scenarios reached 18-29 μg/m 3 . The 2010 annual EU PM 10 limit value (20 μg/m 3 ) would be exceeded by the anthropogenic load recorded for all the air mass transport scenarios, with the exception of the North Atlantic transport (only 15% of the sampling days). Under African air mass transport scenarios (20% of sampling days), the TSP crustal contribution reached near three times the local crustal contribution. It must be pointed out that this crustal input should diminish when sampling PM 10 due to the dominant coarse size distribution of this type of particles. (author)

    Full Text Available The capabilities of X-Ray Fluorescence (XRF core scanners, to acquire high-resolution geochemical data sets in relatively short time, have made them an increasingly popular geochemical screening tool to study sediment cores for palaeoclimatologic and palaeoceanographic purposes (Peck et al., 2007; Rebolledo et al., 2008. These scanners are able to obtain optical images, X-ray radiographs, and continuous geochemical data with a maximum resolution of 200 µm directly from sediment cores (Croudace et al., 2006. Geochemical results are obtained as peak areas of counts per second that are proportional to element concentrations in the sediment, and thus the assumed semi-quantitative nature of these analyses have hampered the use of this type of instruments to monitor and detect pollution at large; where the availability of a fast screening tool that could substantially cut analytical and time costs will certainly be an advantage. This study explores the sensitivity of a ITRAX core scanner (Cox Analytical Systems on sedimentary records from estuarine-like environments in NW (Rías Baixas Galicia and SW Spain (Ría de Huelva. The Galician Rías Baixas sediments are characterized by high contents of organic matter, but in general terms, are not heavily polluted. We have selected one core in the Marín harbour (Ría de Pontevedra and another in the intertidal area of San Simón Bay (inner Ría de Vigo, close to a ceramic factory, which is relatively highly polluted by lead. By the contrary, the Ría de Huelva is one of the most polluted areas in western Europe because of the high acid mining activity together with the chemical industries located in its margins. We have selected a core in the Padre Santo Channel in the confluence of the Odiel and Tinto rivers. ITRAX sensitivity was obtained by establishing equivalences between peak areas and concentrations obtained by traditional analytical techniques such as ICP-MS, ICP-OES and/or conventional XRF of

    Full Text Available A discussão atual sobre a emissão de carbono associada ao uso agropecuário da terra em prejuízo de florestas se ressente de uma visão sistêmica, no que se refere aos fluxos econômicos propriamente, e suas interações, no que tange ao ambiente institucional que os garante. Dado que os esquemas de compensação implicam a entrada e saída de recursos em contextos econômicos amplos e sistêmicos, fundamental é discutir qual o resultado final desses fluxos sobre as condições gerais de reprodução das economias locais. As questões básicas são: a como tais políticas poderão, a partir dos setores rurais, afetar a demanda final efetiva e, por essa via, o valor da produção e as variáveis de valor adicionado de toda a economia e b como as variações na economia afetam as formas de uso da base natural e, portanto, o desmatamento. No que se refere às instituições, o artigo dá especial ênfase às que definem o mercado de terras, porque nele encontra o cerne de questões vitais para o que se discute. O artigo utiliza um modelo ascendente de geração de matrizes de insumo-produto para a economia local do Sudeste Paraense, incorpora nela um balanço de carbono dos setores da produção rural, encontra os multiplicadores e simula quatro situações de politica de contenção de desmatamento e redução das emissões de gases poluentes. A conclusão principal do artigo é que se faz necessário pensar políticas de contenção de desmatamento ligadas indissociavelmente a políticas de produção - a serem operadas por mecanismos que façam convergir as decisões dos agentes com perspectivas macro de desenvolvimento: local, endógeno e sustentável.

Em suma, os resultados indicam que as crianças, através dos pivôs, refletem nas brincadeiras sua individualidade e os valores de sua cultura.In the present study, the pivots used for symbolic transformations in imaginative play by children from 5 cultural groups were compared. The participants were 76 children (41 girls and 35 boys, four to six years old from five Brazilian cultural groups: a small seashore community, a village of Brazilian Indians, and three urban groups of different socioeconomic status (SES from a metropolis (low SES, high SES, and mixed SES. The pivots were classified as natural elements, utensils, and toys. The results showed that: (i the choice of pivots was associated with the available objects: Indian and seashore children used more natural elements; Indian children used more utensils and urban children, more toys; (ii objects that were low structured suited a large variety of symbolic transformations; (iii girls used more models of living beings, and boys, models of vehicles and weapons. In brief, the results indicate that the children, through the pivots, express their individuality and the values of their culture in their play.

    Restricted access to electricity, the existence of an energy matrix based on fossil fueled electricity plants and the lack of financial means by the population living in the Northern region of Brazil to afford the costs with electricity generation, transmission and distribution in the region created the need to implement cross subsidies in the country's Electric Sector Isolated System. The subsidy policies have aimed at allowing the access to electricity for the population and industries in the north of Brazil and at promoting the economic development of this region, but have brought a great cost to society, particularly the Fuel Consumption Account (CCC). This paper evaluates the current structure and the regulatory norms of the electricity sector' subsidies granted to the Isolated Systems, and indicates solutions to the inefficiency associated to cross-subsidization.

    Full Text Available It is acknowledged the role of administrative reforms in Portugal in the introduction of greater technical rationality in the process of public management and the restructuring of public organizations (Bilhim, 2000a; (Mozicafredo, 2000. This rationalization technique is based on the dichotomy between elected and “bureaucrats” appointed (Wilson, 1941 [1887] and Weber (1952 with the “ideal type” of bureaucracy. However Dwight Waldo (1946 and Herbert Simon (1997 [1947] challenged the dichotomy, each for different reasons. Then, in the 1980’s, the dichotomy reemerged and is now alive. In this article, discusses, in the light of the contribution of these founding authors of science of public administration, to what extent the work of a politician, as such, may be taken into account, in the evaluation of a jury, for public managers or top leader of the administration.

    Full Text Available The Southeast region of the state of Pará has been an extraordinarily dynamic area. The great cattle ranching projects financed by the SUDAM were implemented there the sixties, which confronted the old Brazil nut extraction structures and the expansion of family farming both spontaneous and induced, along with major mineral projects and gold mining prospectors. As parts of the process, important structural transformations took place reinforcing the role of the urban centers and their local rural bases in the logistics of new economic sectors conditioned by the formation of the mining economy. This mining economy was a result of the presence of the Vale do Rio Doce Company (CVRD, which has operated its north-system of ferrous metals based in Carajás since 1985. The article presents the results of an input-output analysis with button-up methodology that calculates the economic impacts of the investment program of CVRD from 2004 to 2010, on both the rural and urban local economy and also on the rest of Para State and of Brazil.

    Linear infrastructures, such as highways and railways, present a large environmental impact. Among this impact is the effect on landscape and the modification of the hydrological conditions of the area and an increase in erosive processes (Martin et al., 2011). The increase of erosive processes is specially significant in roadbanks, resulting in high maintenance costs as well as security risks for the use of the infrastructure if it is not properly controlled. Among roadbanks, roadcuts are specially challenging areas for erosion control and ecological restoration, due to their usually steep slope gradient and poor conditions for establishment of vegetation. There are several studies in Mediterranean conditions indicating how the combination of semiarid conditions with, sporadic, intense rainfall events makes a successful vegetation development and erosion control in motorway roadbanks extremely difficult (e.g. Andrés and Jorbat, 2000; Bochet and García-Fayos, 2004). This communication presents the results of the first year evaluation (hydrological year 2012-2013) of five different erosion control strategies on six different locations under different materials on roadcuts of motorways or railways in Andalusia during 2012-2013 using natural rainfall and simulated rainfall. The six sites were located on roadcuts between 10 and 20 m long on slope steepness ranging from 40 to 90%, in motorways and railways spread over different materials in Andalusia. Site 1, Huelva was located on consolidated sand material, sites 2, Osuna I, site 3, Osuna II and site 4, Mancha Real, on marls. Sites 5, Guadix, and 6, Fiñana, were located on phyllites, in comparison a harder material. At each site 12 plots (10 m long and 2 m wide) were installed using metal sheets buried 10 cm within the soil with their longest side in the direction of the roadcut maximum slope. Six different treatments were evaluated at each site, two replications each. These treatments were: 1- A control with bare

    A comparative evaluation is carried out for nearly 5 years (February 2000 to May 2004) of data of aerosol optical depth (AOD) measured at the Aerosol Robotic Network (AERONET) site El Arenosillo (Huelva, southwestern Spain). The AERONET database and the reprocessed data set using a new correction procedure, which we call the KCICLO method, are compared with respect to the aerosol local climatology. The cause and necessity of AOD reprocessing were due to the existence of an observed fictitious diurnal cycle (including negative values) because of a deficient calibration as explained in detail in the companion paper (V. E. Cachorro et al., submitted manuscript, 2007). The derived alpha angstrom coefficient is also compared, as it appears to be an excellent indicator of the AOD data quality, because of its sensitivity to AOD variations and errors. Some illustrative cases show the influence of this fictitious diurnal cycle on the shape and values of diurnal variations of the AOD (or alpha), reaching differences as high as 100%, and the improvement resulting from using the KCICLO method. Absolute and relative differences are evaluated from the overall average of AOD and alpha coefficient of AERONET and KCICLO data series, making an exhaustive analysis for each spectral channel and for every photometer separately. Although great variability is shown for each filter and each photometer, apart from photometer 114 data that did not reach level 2.0, the discrepancy in the AOD local climatology in the four filters varies as a whole from 2.3% to 8.5% (2.4% for alpha coefficient). These values show a considerable reduction because of the compensating effect between the different photometers (positive or negative bias), and several jumps that break the continuity of the data series are observed. When monthly and yearly averages are analyzed, the differences are considerably reduced in such a way that the local climatology is not substantially affected, but we must be cautious

    Changes in nest density and reproductive success of a free–ranging population of white stork (Ciconia ciconia) in the Gardens of ZooBotánico Jerez (Cádiz) were studied from 1990 to 2013. Reproductive data (number of nests and number of chicks per nest) and the effect of rainfall on the reproductive success were analyzed. In addition, a number of chicks were colour–ringed each year and the recovery data were also analyzed. The number of nests found in the area steadily increased during the study period and varied greatly from year to year from 2001 onwards (mean 19, range = 4–35, N = 22 years). Reproductive success also varied greatly among years. Overall, the mean number of chicks per nest was 1.78 ± 1.2 (range = 0–5, N = 439 nests).Reproductive success was strongly influenced by rainfall. It was highest (1.88) in years classified as rainy, medium (1.62) in years classified as normal, and lowest (1.24) in dry years. A total of 404 white storks were ringed, 110 of which were observed a total of 308 times (2.8 + 2.8 times per bird, range 1–12, all year data pooled). Recovery data show that with one exception, all ringed birds were recorded at different habitats of S Spain throughout the year. Remarkably, none was observed at traditional wintering quarters, south of the Sahara in Africa. Juveniles remained in the area (from July to October) soon after leaving our colony, and virtually all of them disappeared from November to January (their first winter) but were recorded again during their first breeding season. On the contrary, adults were repeatedly recorded at different sites in Cádiz, Sevilla and Huelva all year round. These birds showed a strong philopatry as some of them were recorded as breeders in our colony, up to 11 years after ringing. Our data emphasize the importance of both refuse damp and wetland areas for the species, especially in winter, and a shift in the timing of the reproductive season as birds were recorded from November to July

  1. Use of the phosphogypsum wastes in agriculture soils : radiological impact

    The phosphate fertilizer industry produce an important amount of phosphogypsum (PG) as a residue of its activity. Its is well known that such wastes contain significant amounts of natural radionuclides from the U, Th and K series. The raw material for the production (phosphate rock) has uranium activity concentrations of around 1 kBq Kg -1 from which about 15 % passes to the PG. At the Huelva industrial area (SW Spain) the wastes produced per year can reach some 3.10 6 Mg, but in spite of the recent scientific efforts its accumulation still being a problem of great concern for the area. In the other hand, reclamation of sodic soils for agriculture users requires a Ca amendment to diminish Na saturation. Then, PG (with a high proportion of CaSO4 -2H2O) is an effective amendment that has been widely used in the saline-sodic marsh soils from SW Spain. Using PG as an amendment dilutes the radionuclides down to background levels, becoming this practice a possible way to eliminate these wastes with a considerable additional value for the agricultural process. However, it is necessary to study the amount of radioisotopes that can move to water and plants to ensure the radiological safety of the amendment. PG has relatively high concentration of 226 Ra and other radionuclides, with an special concern due to the 22Rn emissions. These wastes could be used to improve the fertility of agriculture soils in a large former marsh area of the Guadalquivir river. Thus, it is interesting to study the levels and behaviour of natural radionuclides within this system to evaluate the radioactive impact if this amendment. An agronomical test is being conducted by one of the authors in an experimental farm in Lebrija (Seville). The soils are treated with 13 and 26 t ha-1 of PG, 30 t ha-1 of manure. Each treatment was repeated twice and continued for two years with beetroot and cotton plant production. We are measuring 226Ra (by alpha counting and gamma spectrometry) and U isotopes (by

    This study is aimed at the analysis of the partitioning of global solar irradiance into its direct and diffuse components at the radiometric station in Badajoz (Spain). The detailed knowledge of the solar radiation field is of increasing interest in Southern Europe due to its use as renewable energy. In particular, the knowledge of the solar radiation partitioning into direct and diffuse radiation has become a major demand for the design and suitable orientation of solar panels in solar power plants. In this study the first measurements of solar diffuse irradiance performed in the radiometric station in Badajoz (Spain) are presented and analyzed in the framework of the partitioning of solar global radiation. Thus, solar global and diffuse irradiance were measured at one-minute basis from 23 November 2009 to 31 March 2010. Solar irradiances were measured by two Kipp&Zonen CMP11 pyranometers, using a Kipp&Zonen CM121 shadow ring for the measurements of solar diffuse irradiance. Diffuse measurements were corrected from the solid angle hidden by the ring and direct irradiance was calculated as the difference between global and diffuse measurements. Irradiance was obtained from the pyranomenters by applying calibration coefficients obtained in an inter-comparison campaign performed at INTA/El Arenosillo, in Huelva (Spain), last September 2009. There, calibration coefficients were calculated using as a reference a CMP11 pyranometer which had been previously calibrated by the Physikalisch-Meteorologisches Observatorium Davos/World Radiation Centre in Switzerland. In order to study the partitioning of the solar radiation, the global and diffuse irradiances have been analyzed for three typical different sky conditions: cloud-free, broken clouds and overcast. Particular days within the period of study have been selected by visual inspection. Along with the analysis of the global and diffuse irradiances themselves, ratios of these irradiances to the downward irradiance at the

    Tsunamis are a moderately frequent phenomenon in the NEAM (North East Atlantic and Mediterranean) region, and consequently in Spain, as historic and recent events have affected this area. I.e., the 1755 earthquake and tsunami affected the Spanish Atlantic coasts of Huelva and Cadiz and the 2003 Boumerdés earthquake triggered a tsunami that reached Balearic island coast in less than 45 minutes. The risk in Spain is real and, its population and tourism rate makes it vulnerable to this kind of catastrophic events. The Indian Ocean tsunami in 2004 and the tsunami in Japan in 2011 launched the worldwide development and application of tsunami risk reduction measures that have been taken as a priority in this field. On November 20th 2015 the directive of the Spanish civil protection agency on planning under the emergency of tsunami was presented. As part of the Spanish National Security strategy, this document specifies the structure of the action plans at different levels: National, regional and local. In this sense, the first step is the proper evaluation of the tsunami hazard at National scale. This work deals with the assessment of the tsunami hazard in Spain, by means of numerical simulations, focused on the elaboration of tsunami hazard maps at National scale. To get this, following a deterministic approach, the seismic structures whose earthquakes could generate the worst tsunamis affecting the coast of Spain have been compiled and characterized. These worst sources have been propagated numerically along a reconstructed bathymetry, built from the best resolution available data. This high-resolution bathymetry was joined with a 25-m resolution DTM, to generate continuous offshore-onshore space, allowing the calculation of the flooded areas prompted by each selected source. The numerical model applied for the calculation of the tsunami propagations was COMCOT. The maps resulting from the numerical simulations show not only the tsunami amplitude at coastal areas but

    Phosphogypsum wastes from phosphate fertilizer industries are stockpiled in stacks with high contamination potential. An assessment of the environmental impact, including the use of geochemical tracers such as rare earth elements (REE) and Cl/Br ratios, was carried out in the phosphogypsum stack located at the Estuary of Huelva (SW Spain). Inside the pile, highly polluted acid pore-waters flows up to the edge of the stack, emerging as small fluvial courses, known as edge outflows, which discharge directly into the estuary. The disposal area is divided into four zones; two unrestored zones with surface ponds of industrial process water and two a priori already-restored zones. However, an extensive sampling of edge outflows conducted in the perimeter of the four zones demonstrates the high potential of contamination of the whole stack, including those zones that were supposedly restored. These solutions are characterized by a pH of 1.9 and concentrations of 6100 mg/L for P, 1970 mg/L for S, 600 mg/L for F, 200 mg/L for NH{sub 4}{sup +}, 100 mg/L for Fe, 10–30 mg/L for Zn, As and U, and 1–10 mg/L for Cr, Cu and Cd. Preliminary restoration actions and those planned for the future prioritize removal of ponded process water and cover of the phosphogypsum with artificial topsoil. These actions presuppose that the ponded process water percolates through the porous medium towards the edge up to reach the estuary. However, geochemical tracers rule out this connection and point to an estuarine origin for these leachates, suggesting a possible tidal-induced leaching of the waste pile in depth. These findings would explain the ineffectiveness of preliminary restoration measures and should be considered for the development of new action plans. - Highlights: • Acidity and contaminants from phosphogypsum leaching are released to an estuary. • Already-restored zones act as a pollution source just as unrestored zones. • Cl/Br ratios and REE patterns were suitable to assess

    Full Text Available The domestic architecture of the western cities of Conventus Hispalensis remains an open line of research still being developed. So, even though there is a previous archaeological literature, there had not been a study establishing a comprehensive overview that integrates de analysis of its architecture, ornamental program, material culture and its incorporation into the urban network. All these explanatory factors are currently of great interest due to the importance of the domestic architecture in Hispania in the past decades (Corrales, 2012, 256. Therefore, the generation of a theoretical framework (Wallace-Hadrill, 1997, 219 was necessary in order to globally understand the urban domestic architecture in the ancient cities of the territory of Huelva. Thanks to new archaeological evidence, this could lead to a renewed interpretative approach. | La arquitectura doméstica de las ciudades occidentales del Conventus Hispalensis continúa siendo una línea de investigación abierta y aún por desarrollar.

Así, pues, se hacía necesaria la generación de un marco de trabajo teórico (Wallace– Hadrill, 1997, 219 mediante el cual, la edilicia doméstica de las ciudades del territorio onubense se entendiese como una reflexión global, en la que, de la mano de las nuevas evidencias arqueológicas, se pudiera producir una aproximación interpretativa renovada.

    Surface ozone is one of the most important photochemical pollutants in the low atmosphere, causing damage to human health, vegetation, materials and climate. The weather (high temperatures and high solar radiation), orography (presence of the Guadalquivir valley) and anthropogenic (the cities of Cádiz, Córdoba, Huelva and Seville and two important industrial complexes) characteristics of the southwestern Iberian Peninsula make this region ideal for the formation and accumulation of ozone. To increase the knowledge of ozone behaviour in this area, the monthly, daily and weekly variations of ozone and its precursors, nitrogen oxides (NO(x) = NO + NO2), were analysed over a 4-year period (2003 to 2006). Using the k-means cluster technique, 12 representative stations of five different areas with different ozone behaviour were selected from a total of 29 monitoring sites. This is the first time that the analysis of these atmospheric pollutants has been carried out for the whole area, allowing therefore a complete understanding of the dynamics and the relationships of these compounds in this region. The results showed an opposite behaviour among ozone and NO and NO2 concentrations in urban and suburban zones, marked by maximums of ozone (minimums NO(x)) in spring and summer and minimums (maximums) in autumn and winter. A seasonal behaviour, with lower amplitude, was also observed in rural and industrial areas for ozone concentrations, with the NO and NO2 concentrations remaining at low and similar values during the year in rural zones due to the absence of emission sources in their surroundings. The daily cycles of ozone in urban, suburban and industrial sites registered a maximum value in the early afternoon (14:00-17:00 UTC) while for NOx two peaks were observed, at 7:00-10:00 UTC and 20:00-22:00. In the case of rural stations, no hourly peak of ozone or NO(x) was registered. The weekend effect was studied by using a statistical contrast tests (Student's t

    In the SW of Spain, just in the confluence of the mouths of the Tinto and Odiel River and in the vicinity of Huelva town, there is a big industrial complex which includes between others an industry devoted during more than 40 years to the production of phosphoric acid, by treating sedimentary phosphate rock by the so-called "wet acid method". As a by-product of the mentioned process it have been produced historically huge amounts of a compound called phosphogypsum, which composition is mostly di-hydrate calcium sulphate containing some of the impurities of heavy metals and natural radionuclides originally present in the raw material. Due to the lack of market for this by-product, it has been mostly piled over some salt-marshes located in the vicinity of the industry, on the bank of the Tinto River. About 100 million tons of phosphogypsum have been piled in an area covering more than 1000 hectares, constituting a clear environmental and radiological anomaly in the zone. The phosphogypsum piles set do not conform obviously a close system. They are interacting with the nearby environment mostly by leaching waters releases from the waters accumulated in them either for its previous use in transporting in suspension the PG from the factory or by rainfall. These waters leaks contain in solution enhanced amounts of heavy metals and radionuclides that can provoke the chemical and radioactive contamination in surroundings soil and salt-marshes areas. In this communication the radioactive influence by the phosphogypsum piles in the surrounding terrestrial environment is evaluated. This contamination is mostly due to radionuclides belonging to the uranium series, which are present originally in the raw material treated in the industry, and afterwards in the generated phosphogypsum, in enhanced amounts in relation to typical soils. In addition, the different dynamics and behavior of different radionuclides will be discussed and analyzed. The gained information in this study

Las regiones que en 1975 poseían mayor densidad poblacional eran Andalucía (17%, Cataluña (16%, Madrid (12%, Valencia (9%, Galicia (7% y Castilla León (7%, abarcando en total un 68% de la población española. Desde 1951 hasta 1975 fueron Madrid, Cataluña y las Islas Canarias las comunidades autónomas con mayor índice de crecimiento poblacional. Desde 1900 hasta 1975, la tendencia general migratoria muestra, en el caso de las provincias del interior, una proporción mayor de emigración que de inmigración, mientras que en las provincias periféricas la diferencia entre ambas tendencias fue reducida. En 1975 Álava, Sevilla y Madrid tenían una densidad poblacional superior a la media nacional, mientras que la densidad poblacional en provincias como Huelva, Almería, Granada, Lugo y Castellón era inferior a la media nacional. En las regiones en desarrollo, la edad media de la población se acerca más a la juventud (la tendencia contraria resulta manifiesta en las regiones agrarias económicamente no desarrolladas.

This river, together with the Tinto River, drains the Iberian Pyrite Belt (IPB), a region containing an abundance of massive sulphide deposits. Because of mining activity dating back to prehistoric times, these two rivers are heavily contaminated. The Odiel and Tinto Rivers drain into a shared estuary known as the Ria of Huelva. This work studies dissolved contaminant data in water of the Odiel River collected by various organisations, between October 1980 and October 2002, close to the rivers entry into the estuary. Flow data for this location were also obtained. The most abundant metals in the water, in order of abundance, are zinc (Zn), iron (Fe), manganese (Mn) and copper (Cu). Arsenic (As), cadmium (Cd) and lead (Pb) are also present but in much lower quantities. The quality of the river water is linked to precipitation; the maximum sulphate, Fe, Zn, Mn, Cd and Pb concentrations occur during the autumn rains, which dissolve the Fe hydroxysulphates that were precipitated during the summer months. In winter, the intense rains cause an increase in the river flow, producing a dilution of the contaminants and a slight increase in the pH. During spring and summer, the sulphate and metal concentration (except Fe) recover and once again increase. The Fe concentration pattern displays a low value during summer due to increased precipitation of ferric oxyhydroxides. The arsenic concentration displays a different evolution, with maximum values in winter, and minimum in spring and summer as they are strongly adsorbed and/or coprecipitated by the ferric oxyhydroxides. Mn and sulphates are the most conservative species in the water. Relative to sulphate, Mn, Zn and Cd, copper displays greater values in winter and lower ones in summer, probably due to its coprecipitation with hydroxysulphates during the spring and summer months. Cd and Zn also appear to be affected by the same

    Full Text Available Changes in nest density and reproductive success of a free–ranging population of white stork (Ciconia ciconia in the Gardens of ZooBotánico Jerez (Cádiz were studied from 1990 to 2013. Reproductive data (number of nests and number of chicks per nest and the effect of rainfall on the reproductive success were analyzed. In addition, a number of chicks were colour–ringed each year and the recovery data were also analyzed. The number of nests found in the area steadily increased during the study period and varied greatly from year to year from 2001 onwards (mean 19, range = 4–35, N = 22 years. Reproductive success also varied greatly among years. Overall, the mean number of chicks per nest was 1.78 ± 1.2 (range = 0–5, N = 439 nests.Reproductive success was strongly influenced by rainfall. It was highest (1.88 in years classified as rainy, medium (1.62 in years classified as normal, and lowest (1.24 in dry years. A total of 404 white storks were ringed, 110 of which were observed a total of 308 times (2.8 + 2.8 times per bird, range 1–12, all year data pooled. Recovery data show that with one exception, all ringed birds were recorded at different habitats of S Spain throughout the year. Remarkably, none was observed at traditional wintering quarters, south of the Sahara in Africa. Juveniles remained in the area (from July to October soon after leaving our colony, and virtually all of them disappeared from November to January (their first winter but were recorded again during their first breeding season. On the contrary, adults were repeatedly recorded at different sites in Cádiz, Sevilla and Huelva all year round. These birds showed a strong philopatry as some of them were recorded as breeders in our colony, up to 11 years after ringing. Our data emphasize the importance of both refuse damp and wetland areas for the species, especially in winter, and a shift in the timing of the reproductive season as birds were recorded from November

    According to the special tasks of archaeologists of the German Archaeological Institute (Madrid department) geophysical investigation campaigns were realized at several sites in Andalusia during the last five years. In Munigua (Province of Seville) - a Roman municipium and centre of metal production - building structures like the city wall and production sites extra muro were investigated by means of GPR measurements. A new method permitting virtual or physical reconstructions of archaeological features in the ground is presented using the original geophysical data and avoiding the speculative aspect of previous reconstruction techniques. In addition the Roman archaeo-metallurgical remains were surveyed in order to investigate the economic base of the Roman town and its environs. Geoelectrical measurements were realized recording the complex resistivity. The extension and depth of slag heaps are estimated using 2D and 3D images of resistivity ρ and phase angle φ. The slag heaps are well-defined by IP effects from the bedrock. The results allow estimating the amount of processed metal in Munigua for the first time. The main focus of the survey in Montes de San Benito (Province of Huelva) was the investigation of the structure of a Celtiberic settlement closely connected to iron production as well. Geomagnetic mapping and GPR measurements were applied in order to detect the buried building structures and the street system. Several single buildings, the main axes and remains of furnaces were localized. A similar procedure was chosen prospecting the fortified hill of Alcorrìn (Province of Malaga), a Phoenician settlement nearby the Mediterranean coast. The both spectacular and rarely researched site is surrounded by an up to 5 m thick wall. Main goal of the two survey campaigns was the internal structure of the hill fort. Using geomagnetic mapping and GPR a second fortification system could be identified. Inside the second ring wall building structures made of mud

    Introduction Four potential meteorite-dropping events happened over Spain during 2007. All them are being carefully studied in the framework of the SPanish Meteor Network (SPMN). Due to the large range of visibility of these events, they usually appear far away from the recording stations, or in broad daylight. The later was the case of the most remarkable of these events: the diurnal bolide witnessed by thousands of people in the afternoon of May 10, at 17h57m01±5s UTC. That magnificent daylight event produced the Puerto Lápice meteorite, an eucrite with a total known weight of about 500 grams [1, 2]. Other wonderful event happened during the afternoon of March 2, 2007 at 18h51m06±1s UTC: a magnificent bolide (Fig. 1) was seen over the Pyrenees by several eyewitnesses located in Catalonia and Aragon, but also from the South of France. Unfortunately it was not recorded by SPMN stations and a very limited number of visual reports were received. Figure 1. The appearance of the March 2, 2007 bolide as drawn made by the second author and fortunate eyewitness from Sant Celoni (Barcelona). Another potential meteorite-dropping diurnal bolide was witnessed from several locations over the south of Spain on the afternoon of June 29. A sonic boom was reported by witnesses located near from the estimated impact area, in the province of Huelva (Andalusia). In some cases these also reported that the bolide generated electrophonic sounds and that the sonic boom was accompanied by vibration of objects inside their houses. However, despite several expeditions to the impact area have been made, the meteorite produced by this bolide has not been found yet. This is mainly due to the high uncertainty in the calculation of the impact point, as the region is quite unpopulated and just about a dozen of eyewitnesses could be interviewed. On the other hand, the characteristics of the vegetation that grows in the area also poses important difficulties to the search tasks. Besides, as in

    In recent years, contamination and its interaction with climate-change variables have been recognized as critical stressors in coastal areas, emphasizing the need for a standardized framework encompassing chemical and biological data into risk indices to support decision-making. We therefore developed an innovative, expert decision support system (Exp-DSS) for the management of contamination in marine coastal ecosystems. The Exp-DSS has two main applications: (i) to determine environmental risk and biological vulnerability in contaminated sites; and (ii) to support the management of waters and sediments by assessing the risk due to the exposure of biota to these matrices. The Exp-DSS evaluates chemical data, both as single compounds and as total toxic pressure of the mixture, to compare concentrations to effect-based thresholds (TELs and PELs). Sites are then placed into three categories of contamination: uncontaminated, mildly contaminated, and highly contaminated. In highly contaminated sites, effects on high-level ecotoxicological endpoints (i.e. survival and reproduction) are used to determine risk at the organism-population level, while ecological parameters (i.e. alterations in community structure and ecosystem functions) are considered for assessing effects on biodiversity. Changes in sublethal biomarkers are utilized to assess the stress level of the organisms in mildly contaminated sites. In Triad studies, chemical concentrations, ecotoxicological high-level effects, and ecological data are combined to determine the level of environmental risk in highly contaminated sites; chemical concentration and ecotoxicological sublethal effects are evaluated to determine biological vulnerability in mildly contaminated sites. The Exp-DSS was applied to data from the literature about sediment quality in estuarine areas of Spain, and ranked risks related to exposure to contaminated sediments from high risk (Huelva estuary) to mild risk (Guadalquivir estuary and Bay of

    Full Text Available Abstract Background Multiple guidelines and systematic reviews recommend sealant use to reduce caries risk. Yet, multiple reports also indicate that sealants are significantly underutilized. This study examined the knowledge, opinions, values, and practice (KOVP of dentists concerning sealant use in the southwest region of Andalusia, Spain. This is a prelude to the generation of a regional plan for improving children’s oral health in Andalusia. Methods The survey’s target population was dentists working in western Andalusia, equally distributed in the provinces of Seville, Cadiz, and Huelva (N=2,047. A convenience sample of meeting participants and meeting participant email lists (N=400 were solicited from the annual course on Community and Pediatric Dentistry. This course is required for all public health sector dentists, and is open to all private sector dentists. Information on the dentist’s KOVP of sealants was collected using four-part questionnaire with 31, 5-point Likert-scaled questions. Results The survey population demographics included 190 men (48% and 206 women (52% with an average clinical experience of 10.6 (± 8.4 years and 9.3 (± 7.5 years, respectively. A significant sex difference was observed in the distribution of place of work (urban/suburb (p=0.001, but no sex differences between working sector (public/private. The mean ± SD values for each of the four KOVP sections for pit and fissure sealants were: knowledge = 3.57 ± 0.47; opinion = 2.48 ± 0.47; value = 2.74 ± 0.52; and practice = 3.48 ± 0.50. No sex differences were found in KOVP (all p >0.4. Independent of sex: knowledge statistically differed by years of experience and place of work; opinion statistically differed by years of experience and sector; and practice statistically differed by years of experience and sector. Less experienced dentists tended to have slightly higher scores (~0.25 on a Likert 1–5 scale. Statistically significant correlations were

    Full Text Available En los últimos años, un número creciente de estudios sugiere que los incrementos en los niveles de contaminación atmosférica pueden causar efectos a corto plazo sobre la salud, incluso con niveles de contaminación cercanos o inferiores a los considerados hasta ahora como seguros. Los distintos enfoques metodológicos y la diversidad de técnicas de análisis utilizadas han dificultado la comparabilidad directa entre los resultados obtenidos, impidiendo llegar a conclusiones claras. Ello ha estimulado la puesta en marcha de proyectos multicéntricos, como el proyecto APHEA (short-term effects of Air Pollution on Health: a European Approach, dentro del ámbito europeo. El proyecto EMECAM se enmarca en el contexto de los estudios multicéntricos citados y tiene una proyección amplia en el ámbito nacional español. En él se incluyen 14 ciudades españolas (Barcelona, Gran Bilbao, Cartagena, Castellón, Gijón, Huelva, Madrid, Pamplona, Sevilla, Oviedo, Valencia, Vigo, Vitoria y Zaragoza que representan diferentes situaciones sociodemográficas, climáticas y ambientales, sumando un total cercano a nueve millones de habitantes. El objetivo del proyecto EMECAM es evaluar el impacto a corto plazo de la contaminación atmosférica, en el conjunto de las ciudades participantes, sobre la mortalidad por todas las causas, en toda la población y en personas de 70 y más años, y por causas respiratorias y del aparato circulatorio. Para ello, con un diseño ecológico, se analizan los datos de las series temporales tomando como unidad los datos diarios de mortalidad, contaminantes, temperatura y otros factores, obtenidos de registros de instituciones públicas. El periodo de estudio, aunque no es exactamente el mismo para todas las ciudades, está comprendido en todos los casos entre los años 1990 y 1996. El cálculo de las medidas de asociación se realiza mediante regresión autorregresiva de Poisson. En una fase posterior los resultados de cada

    Complete text of publication follows. Recently a number of papers have been published by European groups [1], [2], [3], [4] organized mainly by western- and middle European laboratories, in which comparative data have been presented from co-ordinated research programs for air qualification in a number of urban sites based on joint evaluation of elemental composition and reflectance of ambient fine aerosol particles. The time interval June 2000 to December 2001 scanned in the co-ordinated program of Goetchi et al [1] is mainly covered by a part of our long term data set. All together 107 sampling days have been used here work over the above time interval. Due to the gross parallelism of the total observation periods and the principal similarity of the used analytical methods in their and our works, we found it plausible to find out how much the air quality characteristics observed at our location fit in the general European trends. Sampling sites arranged in selected European regions are numbered as follows: West and Central Europe: Antwerp South (1), Antwerp City (2), Paris (3), Erfurt (4), Basel (5); Spain: Barcelona (6), Galdakao (7), Albacete (8), Oviedo (9), Huelva (10); Alpine France: Grenoble (11); Northern Italy: Pavia (12), Turin (13), Verona (14); England: Ipswitch (15), Norwich (16); Scandinavia: Reykjavik (17), Gothenburg (18), Umea (19), Uppsala (20); Estonia: Tartu (21); Hungary: Debrecen (22). For a first orientation about the existence of similarities and differences within and among the regional features, respectively, yearly average concentrations are presented in Figure 1 for silicon, and sulphur elemental constituents and PM2,5 integral concentrations for sites 1 22. Silicon, sulphur, and black carbon are considered as main representatives of the crustal material, traffic and long-range background pollution components, respectively, while PM2.5 is a parameter accepted for measuring overall air quality from the point of view of human health

    The Sancho reservoir is an acid mine drainage (AMD)-contaminated reservoir located in the Huelva province (SW Spain) with a pH close to 3.5. The water is only used for a refrigeration system of a paper mill. The Sancho reservoir is holomictic with one mixing period per year in the winter. During this mixing period, oxygenated water reaches the sediment, while under stratified conditions (the rest of the year) hypoxic conditions develop at the hypolimnion. A CE-QUAL-W2 model was calibrated for the Sancho Reservoir to predict the thermocline and oxycline formation, as well as the salinity, ammonium, nitrate, phosphorous, algal, chlorophyll-a, and iron concentrations. The version 3.7 of the model does not allow simulating the oxidation of Fe(II) in the water column, which limits the oxygen consumption of the organic matter oxidation. However, to evaluate the impact of Fe(II) oxidation on the oxycline formation, Fe(II) has been introduced into the model based on its relationship with labile dissolved organic matter (LDOM). The results show that Fe oxidation is the main factor responsible for the oxygen depletion in the hypolimnion of the Sancho Reservoir. The limiting factors for green algal growth have also been studied. The model predicted that ammonium, nitrate, and phosphate were not limiting factors for green algal growth. Light appeared to be one of the limiting factors for algal growth, while chlorophyll-a and dissolved oxygen concentrations could not be fully described. We hypothesize that dissolved CO2 is one of the limiting nutrients due to losses by the high acidity of the water column. The sensitivity tests carried out support this hypothesis. Two different remediation scenarios have been tested with the calibrated model: 1) an AMD passive treatment plant installed at the river, which removes completely Fe, and 2) different depth water extractions. If no Fe was introduced into the reservoir, water quality would significantly improve in only two years

    Full Text Available This study establishes the controlling factors in the soil development in the ancient coastal plain of the Guadalquivir River along the southern Spanish coast (Huelva shortly before 100 ka BP. The macro and micromorphological study indicates that a sedimentation hiatus allowed soil formation (extensive clay illuviation together with the development of widespread redoximorphic features linked to iron oxide depletion and accumulation. Groundwater fluctuations driven by the overall sea-level rise during the onset of the last interglacial period triggered the pervasive occurrence of redox processes, probably acting in the coastal zone from the whole Middle Pleistocene as witnessed in inland outcrops. The resulting redoximorphic pedofeatures show a differential development in the studied zone, which is linked mainly to the activity of the Torre del Loro Fault leading regional differential upwarping of the ancient coastal area as well as local water-escape processes in the fault zone. Petrological, mineralogical and micromorphological data strongly suggest that the occurrence of multiple inheritances of iron-rich pedofeatures from previous Plio-Pleistocene weathering profiles developed under warmer and humid climatic conditions. Several pedofeatures (corroded quartz grains and runiquartz do not correspond to the temperate oceanic climate prevailing in the zone during soil formation, and are reworked from former stronger weathering conditions. They are included in strongly iron-impregnated opaque domains that can be interpreted as inherited iron-rich nodules or clasts already present in the host sediments. These iron-rich pedofeatures have been subject to subsequent iron mobilization giving place to the iron depletion and accumulation domains observed in the micromorphological scale. Differential iron bleaching is not always linked to the fissure and/or pore-system present in the groundmass, suggesting the occurrence of differential water and sediment

    The subject of this work concerns with the measurement of absolute calibration factors for the use of CR-39 as an absolute detector in indoor and daughters monitoring. Up to now the usefulness of calibration factors was restricted to environmental conditions equal (or very close) to those worthing during their determinations. This fact is consequence of the difficulties related to the understanding of the plate-out properties of radon daughters activity in the air. The plate-out effects on radon daughters monitoring performed by SSNTDs are studied. Our experimental results are in agreement with those of other authors about the great sensitivity of CR-39 to the plate-out effects, fact that recommended its use in this work. Being succeeded in the employment of CR-39 as an alpha-spectrometer we concluded that some important information (like the radon daughters deposition rates on the walls of an environment) can be achieved. The knowledge about the behavior of plate-out made possible the determination of the ranges in zenithal angle and energy where CR-39 can detect alpha-particles with efficiency of 100%, at our conditions of track observation. In this way, we obtained calibration factors for CR-39 that are weakly dependent on environmental conditions. We think that these results can contribute to the improvement of RD (Radiation Detector) detection techniques. (author). 159 refs, 106 figs, 05 tabs.

    Full Text Available OBJETIVO: Descrever a participação das atividades de saúde na economia brasileira entre 2000 e 2007 em termos de valor adicionado e geração de postos de trabalho. MÉTODOS: Foram utilizados dados secundários do Instituto Brasileiro de Geografia e Estatística para os anos de 2000 a 2007. Foram analisadas as seguintes atividades: saúde pública, produção de serviços de saúde e serviços sociais privados, planos de saúde, indústria farmacêutica, indústria de equipamentos médicos e comércio de produtos farmacêuticos. Foi calculada a participação de cada atividade no total da economia e no setor saúde, a participação percentual dos componentes do valor adicionado na ótica da renda para as atividades de saúde e o crescimento real do valor adicionado por atividade de saúde. Para complementar as análises, foram levantados os rendimentos médios do trabalho e o número de postos de trabalho por atividade. RESULTADOS: A participação do setor saúde na economia variou de 5,2 a 5,8%. Cresceu a participação da saúde pública (de 1,7 para 2,0% e caiu a dos serviços de saúde privados (de 2,4 para 2,2%. O crescimento médio anual do setor (3,5% foi próximo ao da economia (3,4%. A participação do comércio de produtos farmacêuticos no setor aumentou de 9,1 para 13,2%. As atividades com maior crescimento acumulado foram: fabricação de aparelhos médico-hospitalares (42,7%, saúde pública (39,4% e planos e seguros de saúde (35,8%.

CONCLUSÕES: O setor saúde tem uma participação importante na economia brasileira, embora essa participação ainda seja inferior àquela observada em países de alta renda. O aumento da participação dos serviços públicos no valor adicionado setorial, o crescimento das margens de comercialização dos produtos farmacêuticos e o crescimento real inferior à média setorial da indústria farmacêutica devem ser monitorados.OBJECTIVE: To describe the share of health care activities in the Brazilian economy between 2000 and 2007 in terms of economic value added and creation of jobs. METHODS: Secondary data from the Brazilian Institute of Geography and Statistics (IBGE for the years 2000 to 2007 were employed. The following health care activities were analyzed: public health, production of private health services and private social services, health insurance, the pharmaceutical industry, medical equipment manufacturing, and medical and pharmaceutical product sales. The share of each activity in the total economy and in the health care sector was calculated, as well as the percentage share of value-added components from the perspective of income for health care ­activities and the real growth in value added by health care activity. To complement the analysis, the average income of workers and the number of jobs per activity were ­established. RESULTS>: The participation of the health care sector in the economy ranged from 5.2% to 5.8%. The share of public health increased from 1.7% to 2.0%, and that of private healthcare services fell from 2.4% to 2.2%. The average annual growth of 3.5% for the sector was close to the 3.4% annual growth recorded for the economy. The share of medical and pharmaceutical product commerce in the sector increased from 9.1% to 13.2%. The activities with the highest accumulated growth were: manufacture of medical/hospital devices (42.7%, public health (39.4%, and health insurance (35.8%. Health care represented 4.1% of jobs in the economy in 2000 vs. 4.4% in 2007, with 1 million new jobs. Income from labor represented 6.7% of the total economy in 2000 and 7.5% in 2007. CONCLUSIONS: The health care sector has an important stake in the Brazilian economy, although this share is still lower than that observed in high-income countries. The rising share of public services in the sector’s added value, the relative growth of medical and pharmaceutical product sales margins, and a real growth below the average for the pharmaceutical industry should be monitored.

    The use of the solar energy, for thermal or photovoltaic ends, depends basically on the amount of radiation that reaches the ground in the place where desires to carry through this use, defining the necessary area of the collectors, or panels, that in turn are the main components of the final cost of the system and, therefore, of the viability or not on its use. The incident radiation in the terrestrial surface is minor that one reaches the top of the atmosphere due to the absorption and dispersion factors. The objective of this work is to present a model of forecast the monthly average radiation for ends of use in systems of flat solar collectors for heating water, in the city of Campinas - Sao Paulo, Brazil. This work has been developed by the Hydrogen Laboratory of the Institute of Physics of the UNICAMP, being also used for other applications with solar energy. Based in the radiation data, taken from a local station, a theoretical study was developed to calculate a parameter of loss of radiation when this cross the atmosphere.

    Full Text Available AIM: The purpose of this work was to determine genera diversity, structural attributes and distribution of the Hydrachnidia assemblages and their possible influences with certain abiotic parameters along the sub-basin of the Grande River, a 6th order stream in the province of San Luis; METHODS: four sampling sites (C1, E1, E2 and E3 were established in two different hydrological periods: high waters (HW and low waters (LW. Twenty-four samples were obtained using Surber sampler, and the hydraulic, physical and chemical characterization of the sampling sites was carried out. Density (ind.m-2, genus richness, Shannon-Wiener diversity index and Kownacki's dominance index were calculated; RESULTS: sixteen Hydrachnidia genera were observed. No significant differences were found between the abiotic parameters of each site. A positive correlation of Sperchon, Torrentícola and Neoatractides was observed in relation to flow and current velocity whereas Hygrobates showed a negative correlation. No significant differences were observed in Hydrachnidia abundances among the sites in HW and LW and between the pairs of each site in HW and LW. The genera with the highest densities were Hygrobates, Limnesia and Atractides, of which the first two were widely distributed. The rest only appeared sporadically. According to Kownacki's index Hygrobates and Limnesia were "dominant", Atractides were "subdominant" and the rest were "non dominant"; CONCLUSIONS: The found genera were distanced systematically and philogenetically. However, the specimens belonging to these genera exhibited very similar morphological characteristics, which were adaptations to rheophilous habitats. The representativity of Hygrobates and Limnesia might be due to the great abundance of their hosts and preys in the sub-basin. The decrease in the densities and the changes in the Hydrachnidia composition in E3 (post-dam site might be explained by the biotic interactions previously mentioned.OBJETIVO: O objetivo deste trabalho foi conhecer a diversidade de gêneros, os atributos estruturais e a distribuição da comunidade de hidracáridos, como assim também a sua possível influência sobre certos parâmetros abióticos, na sub-bacia do Rio Grande, San Luis; MÉTODOS: estabeleceram-se quatro locais de amostragem (C1, E1, E2 e E3 em dois períodos hidrológicos: águas altas (AA e águas baixas (AB. Obtiverem-se 24 amostras com rede Surber e se realizou a caracterização hidráulica, física e química dos locais de amostragem. Calculou-se a densidade (ind.m-2, a riqueza genérica e o índice da diversidade de Shannon-Wiener; RESULTADOS: registraram-se 16 gêneros de hidracáridos. Não houve diferenças significativas entre cada local com relação aos parâmetros abióticos. Observou-se uma correlação positiva entre Sperchon, Torrentícola e Neoatractides com relação ao fluxo e à corrente, ao passo que Hygrobates mostrou uma correlação negativa. Não houve diferenças significativas nas abundâncias absolutas de hidracáridos entre os locais em AA e AB nem entre os pares de cada local em AA e em AB. Os gêneros que apresentaram as maiores densidades foram Hygrobates, Limnesia e Atractides, dos quais os dois primeiros apresentaram-se mais amplamente distribuídos. Os demais gêneros somente apareceram esporádicamente. De acordo com o índice de Kownacki, Hygrobates e Limnesia foram "dominantes", Atractides foi "subdominante", e o resto foi "não-dominante"; CONCLUSÕES: os gêneros encontrados apresentaram-se distantes tanto filogenéticamente quanto sistemáticamente. Porém, os espécimes desses gêneros foram similares morfológicamente, apresentando características adaptativas à habitats teófilos. A representatividade de Hygrobates e Limnesia poderia se dever à grande abundância de seus hospedeiros e presas na sub-bacia. A diminuição na densidade e as mudanças na composição de hidracáridos em E3 (local após barragem poderiam ser explicadas pelas interações abióticas antes mencionadas.

Input data were the atmospheric deposition of radionuclides of Chernobyl origin, the concentrations of radionuclides in the Black Sea, hydrological, morphological and environmental (temperature, salinity, pH, etc.) data. The performances of the models were assessed by comparison of model results with time dependent empirical data of radionuclide concentration in the estuary. (3) 3 H migration in the Loire River (France). This scenario was aimed at assessing the dispersion of tritium releases at different points in the river, along a large domain (∼ 350 km) and over a period of six months. Water discharges from tributaries, hydrological data and tritium discharges from four nuclear power plants were supplied as input data. The results were compared with empirical measurements of tritium concentration at Angers, a city along the river. (4) Release of radionuclides into the Techa River (Russia). The objective of this scenario was to test models for radioactive contamination of river water and bottom sediments by 90 Sr, 137 Cs and 239,240 Pu. The scenario was based on data from the Techa River (South Urals) which was contaminated mainly in 1949-1952 as a result of discharges of liquid radioactive waste into the river. (5) Behaviour of 226 Ra in the Huelva estuary (Spain). The estuary was affected by contamination from former phosphate industry. The exercise consisted of providing the time evolution of the total 226 Ra inventory in the bed sediments and the time evolution of the concentration in the water column.

    The chemical composition and concentration of aerosols at a certain site can vary depending on season, the air mass source region and distance from sources. Regardless of the environment, new particle formation (NPF) events are one of the major sources for ultrafine particles which are potentially hazardous to human health. Grown particles are optically active and efficient CCN resulting in important implications for visibility and climate (Zhang et al., 2004). The study presented here is intended to provide information about various aspects of continental, urban and marine air masses reflected by wind patterns of the air arriving at the measurement site. Additionally we will be focusing on NPF events associated with different types of air masses affecting their emergence and temporal evolution. Measurements of the ambient aerosol, various trace gases and meteorological parameters were performed within the framework of the DOMINO (Diel Oxidant Mechanisms In relation to Nitrogen Oxides) project. The field campaign took place from mid-November to mid-December 2008 at the atmospheric research station "El Arenosillo" located at the interface between a natural park, industrial cities (Huelva, Seville) and the Atlantic Ocean. Number and mass as well as PAH and black carbon concentrations were measured in PM1 and size distribution instruments covered the size range 6 nm up to 32 μm. The chemical composition of the non-refractory submicron aerosol was measured by means of an Aerosol Mass Spectrometer (AMS). In order to evaluate the characteristics of different air masses linking local and regional sources as well as NPF processes, characteristic air mass types were classified dependent on backwards trajectory pathways and local meteorology. Large nuclei mode concentrations in the number size distribution were found within continental and urban influenced air mass types due to frequently occurring NPF events.

    structures of the local flows and their impact on emissions; nevertheless, these mesoscale systems are developed within the scope of a synoptic circulation, which also affects both the breeze development and the pollutant transport. In order to take the relationship between the different atmospheric scales into account, we used the CAMx photochemical model coupled with the MM5 meteorological model, both configured with a system of nested grids. The study domain covers an area of 28224 km2, with 2 km horizontal resolution and 18 vertical layers up to a height of 5 km with high resolution in the levels close to the ground. This paper assesses the impact over the hourly and 8-hourly maximum daily ozone concentrations of four reduction strategies in an area with complex terrain: (i) 25% reduction in VOC and NOx from industry and traffic, (ii) 50% reduction in NOx and VOC from the industry, (iii) 50% reduction in NOx and VOC from traffic, and (iv) 100% reduction in NOx and VOC from the petrochemical plant and the refinery. The study area has large industrial sources, such as a petroleum refinery, a petrochemical plant, several chemical complexes and co-generation power plants, among others. The study area includes the cities of Huelva (148,000 inhabitants), Seville (699,760 inhabitants) and Cadiz (127,200 inhabitants). The analyses presented in this work provide an assessment of the effectiveness of several strategies to reduce ozone pollution in different meteorological scenarios.

  9. Flash flood prediction in large dams using neural networks

    A flow forecasting methodology is presented as a support tool for flood management in large dams. The practical and efficient use of hydrological real-time measurements is necessary to operate early warning systems for flood disasters prevention, either in natural catchments or in those regulated with reservoirs. In this latter case, the optimal dam operation during flood scenarios should reduce the downstream risks, and at the same time achieve a compromise between different goals: structural security, minimize predictions uncertainty and water resources system management objectives. Downstream constraints depend basically on the geomorphology of the valley, the critical flow thresholds for flooding, the land use and vulnerability associated with human settlements and their economic activities. A dam operation during a flood event thus requires appropriate strategies depending on the flood magnitude and the initial freeboard at the reservoir. The most important difficulty arises from the inherently stochastic character of peak rainfall intensities, their strong spatial and temporal variability, and the highly nonlinear response of semiarid catchments resulting from initial soil moisture condition and the dominant flow mechanisms. The practical integration of a flow prediction model in a real-time system should include combined techniques of pre-processing, data verification and completion, assimilation of information and implementation of real time filters depending on the system characteristics. This work explores the behaviour of real-time flood forecast algorithms based on artificial neural networks (ANN) techniques, in the River Meca catchment (Huelva, Spain), regulated by El Sancho dam. The dam is equipped with three Taintor gates of 12x6 meters. The hydrological data network includes five high-resolution automatic pluviometers (dt=10 min) and three high precision water level sensors in the reservoir.

    How does the estimated prevalence of infertility among 30- to 49-year-old women vary when using different approaches to its measurement? The prevalence of women with difficulties in conceiving differed widely according to the measurement approach adopted. Establishing the true magnitude of infertility as a public health problem is challenging, given that it is not categorized as a disability or chronic condition and may be largely unreported. The time required to conceive is an increasingly frequent concern among couples of reproductive age. Population-based studies do not consider multiple approaches to infertility measurement in the same sample. A face-to-face cross-sectional population-based survey of 443 women aged between 30 and 49 years residing in Huelva, southern Spain, was carried out. The sample size estimation was based on an assumed prevalence of infertility of 19%, a sampling error of ±4.84 percentage points, a design effect of 1.8 and a 95% confidence level. The information was collected in 2011. Self-reported information was gathered on socio-demographic data, pregnancy history, time required to become pregnant and perception of difficulties in becoming pregnant. Eight approaches to the estimation of infertility prevalence were considered: diagnosed infertility, subjective infertility, 1-year infertility, primary infertility, secondary infertility and subfertility based on the time taken to conceive (6, 12 or 24 months). Calibration estimators (indirect estimation techniques) were used to extrapolate the infertility prevalences to the whole of Spain. The response rate was 61.05%. Among 30- to 49-year-old Spanish women, 1.26% had a clinical diagnosis of infertility, 17.58% did not achieve pregnancy in 1 year (1-year infertility), 8.22% perceived difficulties in procreation (subjective infertility), 6.12% had not succeeded in having biological children (primary infertility) and 11.33% had not been able to have another biological child (secondary

    Full text: The Centro Nacional de Aceleradores (National Accelerator Center, CNA), the first and for the moment the only Spanish ion beam analysis (IBA) laboratory, was set up in 1998 in the University of Seville (Spain). This laboratory was created with the aim to fulfill the increasing demand for IBA techniques existing in Spain. This facility is based on a 3 MB pelletron tandem accelerator, which is being used for interdisciplinary studies concerning Material Science, Art, Archaeology, Biology, Medicine, Environmental Science, etc. In addition, the works for a cyclotron laboratory are commencing now. This paper reports on the most recent applications in the field of Environmental Science carried out in our laboratory. Remediation of metal-contaminated soils and waters poses a challenging problem due to its implications in the environment and the human health. A possible solution to this problem is the phytoremediation, i.e. the process of using plants for environmental restoration taking advantage of the ability of certain terrestrial plants to absorb and accumulate metals, removing them from soils and aqueous streams. These plants are called metal hyper accumulators if they accumulate for instance more than 0.01% of Cd, 0.1% of Ni or 1% of Zn per dry weight in their shoots. For example, Cd is readily transported and accumulated in the shoots of several plant species, being a favourable target metal for this technology. In recent works making use of nuclear microscopy techniques, we investigated the sites of metal localization within the leaves of metal hyper accumulator Arabidopsis thaliana, when plants are grown in a cadmium-rich environment, and we proved that cadmium is sequestered within the trichomes on the leaf surface. The Donana Natural Park is an internationally important wetland area of 280,000 ha in the Huelva-Seville-Cadiz triangle in Southern Spain, which includes natural beaches, dunes, pine forests and marshlands as the most relevant habitats.

    ECR ion source was installed and during the installation period beam from the cyclotron was not available for users. The source was commissioned in May but its coupling with the cyclotron requires some additional changes to the cyclotron injection system. These will be introduced in summer 2011 and accelerated beams from the new source should be available for experiments in the second half of 2011. Due to the installation of the new source, the spring experimental campaign was limited to a few weeks in June and the beginning of July. Nevertheless, we would like to welcome new users - a group of physicists from the University of loannina, Greece, led by Prof. Athena Pakou and an international team led by Dr. Marcus Scheck. In September, construction work on new buildings for the Faculties of Physics, Biology and Chemistry started in earnest in the immediate neighbourhood of our laboratory. This caused many unexpected cuts in the power and water supplies and, in addition, some flooding in the basement of our building. We were therefore forced to limit our activity and postpone a series of planned experiments to the first half of 2011. Fortunately, in October we were still able to run some simple experiments for the 6 th edition of the Polish Workshop on Acceleration and Applications of Heavy Ions, a one week event for undergraduate students from Polish universities. From 2011 onwards, this activity will be extended - we will organise an annual two-week workshop for students from abroad within the framework of the Erasmus - LLP Intensive Programme. This initiative has received the necessary funding from the Polish National Agency of Erasmus - the Foundation for the Development of the Educational System Lifelong Learning. Programme. The workshop will be organised jointly with the University of Sofia, Bulgaria, and the University of Huelva, Spain. It does not happen every year so I would like to mention that the Heavy Ion Laboratory co-organised an international conference

    Full Text Available In the present work, morphometric and cytogenetic analyses were carried out in populations of the fish Astyanax fasciatus (Characidae from Contas and Recôncavo Sul River basins (State of Bahia, Brazil, providing new data on the genetic structure of this species along the region. Based on morphologic measurements, we observed that populations from the same hydrographic basin were more similar to each other (Contas and Preto do Costa Rivers, and remarkably divergent from Recôncavo Sul (Mineiro Stream, as indicated by clustering analysis. Cytogenetic data revealed a same diploid number for all populations (2n = 48, but distinct karyotype formulae (8M+24SM+12ST+4A, FN = 92 in Contas River, 8M+24SM+10ST+6A, FN = 90 in Preto do Costa River, and 8M+18SM+16ST+6A, FN = 90 in Mineiro Stream. Ag-NORs were identified at telomeres on a subtelocentric chromosome pair, although multiple ribosomal sites have been detected in some specimens from Contas River. These results show that A. fasciatus populations from northeastern river basins are well differentiated and present peculiar cytogenetic features when compared to populations from other regions. Therefore, the apparent chromosomal plasticity of this species, likely to represent a complex of cryptic forms, is corroborated. Finally, we demonstrated that morphological features can be successfully used to support other sources of genetic information.

    Full Text Available A funcionalidade é uma dimensão crucial da saúde da pessoa idosa. O objetivo desse trabalho é investigar os elementos que participam da construção dos significados da incapacidade para o idoso residente na cidade de Bambuí (MG. Trata-se de uma abordagem qualitativa na qual o modelo de signos, significados e ações foi utilizado na coleta e análise dos dados. Foram entrevistados 57 idosos (30 mulheres; 27 homens com idades entre 61 e 96 anos, cadastrados nas Unidades Básicas de Saúde (SUS da cidade. Os idosos compreendem a funcionalidade/incapacidade (disease, como o "dar conta/não dar conta" ou "dar trabalho" (illness. "Não dar conta" refere-se às perdas funcionais inexoráveis atribuídas à velhice, enquanto "Dar trabalho" a uma condição definitiva que gera dor e sofrimento à pessoa e a quem dela cuida. As maneiras de lidar com o "não dar conta" passam por se conformar, enquanto com o "dar trabalho", orar. A religiosidade e o conformismo podem ajudar nos momentos de crise; mas, revelam a carência de recursos e de alternativas de apoio e de intervenção nos casos mais graves.

Como a taxa de câmbio tem outros determinantes além da absorção interna, o pressuposto dos déficits gêmeos com frequência não é válido. Essas foram de balanço de pagamentos e se caracterizaram por elevados déficits em conta corrente e forte aumento da dívida externa e/ou por forte aumento do déficit em conta corrente, que levaram os credores a se persuadirem que o problema do país era ou de liquidez ou de solvência, ou ambos, e decidirem, subitamente, suspender a rolagem da dívida externa do país.

    García García, J.; García García, B.

    2006-01-01

    Sole (Solea senegalensis) is of great interest to marine aquaculture in the Mediterranean because of its relatively fast growth and good commercial prospects (high price). However, the wide mean annual variation in the temperature of Mediterranean sea water (14-26 deg C) is a limiting factor for the ongrowing of this species; the optimum for this process is 19-20 deg C. One of the possible mid-term solutions for ensuring a constant year-round temperature is to ongrow these fish in tanks conta...

    2010-01-01

    Privacy preservation has become a major issue in many data analysis applications. When a data set is released to other parties for data analysis, privacy-preserving techniques are often required to reduce the possibility of identifying sensitive information about individuals. For example, in medical data, sensitive information can be the fact that a particular patient suffers from HIV. In spatial data, sensitive information can be a specific location of an individual. In web surfing data, the information that a user browses certain websites may be considered sensitive. Consider a dataset conta

    Full Text Available O mercado de trabalho nos últimos anos tem dado sinais de recuperação, destacando-se a maior formalização dos empregos. A população economicamente ativa, no conceito amplo do IBGE, distribui-se entre o mercado de trabalho por conta-alheia, que abrange os empregados de estabelecimento, o serviço doméstico remunerado e os desempregados, e o trabalho por conta-própria, que abarca os trabalhadores autônomos, os membros de suas famílias que trabalham sem remuneração, os empregadores e os trabalhadores na produção agrícola para o consumo próprio e na autoconstrução. No mercado de trabalho por conta-alheia, a mulher apresenta maiores taxa de desemprego e informalidade no vínculo do emprego. No trabalho por conta-própria, a presença feminina é maior entre os não-remunerados e na produção agrícola para o consumo próprio, enquanto os homens têm maior participação entre os autônomos e empregadores. O mercado de trabalho por conta-alheia abrange dois terços da PEA e, recentemente, tem crescido mais fortemente do que o por conta-própria. No mercado de trabalho por conta-alheia, o emprego formalizado tem crescido mais fortemente do que o sem carteira. A participação da mulher tem-se ampliado nos dois tipos de trabalho, mas as diferenças de renda por sexo continuam muito grandes. Apesar da maior participação, as mulheres continuam segregadas em ocupações de menor renda, tanto no mercado de trabalho por conta-alheia como naquele por conta-própria.El mercado de trabajo en los últimos años ha dado señales de recuperación, destacándose la mayor formalización de los empleos. La población económicamente activa, en el concepto amplio del IBGE, se distribuye entre el mercado de trabajo por cuenta ajena, que abarca a los empleados de estabelecimiento, el servicio doméstico remunerado y los desempleados, y el trabajo por cuenta propia, que abarca a los trabajadores autónomos, los miembros de sus familias que trabajan

Genotypes with a more favourable ratio between linoleic and linolenic acids were obtained in the irradiated F 2 -M 2 population. The obtained radio-induced mutants are used for the production of new varieties of winter rape without erucic acid at the Slapy Breeding Station. (author)

    2011-01-01

    Este trabalho tem como objetivo discutir sobre a citação no texto acadêmico-científico. Argumentamos em favor da necessidade de se reivindicar o citar em sua dimensão dialógica, partindo do pressuposto de que o olhar concebido pelos manuais de metodologia científica não dá conta da complexidade que recobre o citar no texto acadêmico-científico. Apoiando-nos em pressupostos teóricos do dialogismo bakhtiniano e em estudos de Maingueneau (1996, 2002), Charaudeau; Maingueneau (2004), Boch; Grossm...

    Full Text Available This study examined the spatial and temporal variations of six important parameters of the salt accumulation process in water samples collected along section urban of Contas River. The Na+, K+, Ca2+ and Mg2+ concentrations were determined by FAAS. The conductivity, total dissolved solids, Na+ and Ca2+ presented the largest seasonal and spatial variations in the urban area demonstrated that are appropriate indicators of urban contamination. The readily soluble salts in drainage urban, contribute for the degradation of the water of rivers located in semi-arid zones.

    2010-01-01

    As opções de política externa do Brasil são limitadas, tendo em conta os recursos materiais superiores das grandes potências establecidas. Soft balancing envolve estratégias institucionais, tais como a formação de coalizões ou ententes diplomáticas limitadas, como BRIC, para restringir o poder das grandes potências estabelecidas. Os países BRIC tinham constado dentre os precursores mais fortes de mudança da diplomacia mundial e por sua vez se beneficiam mais destas mudanças de poder global. D...

    OpenAIRE

    de Carvalho, Gilmar

    2016-01-01

    Por conta de uma pretensa objetividade jornalística, pretendemos arrancar de Patativa o máximo de informações. É a falsa ideia da produtividade. Mas o que ele tem a dizer estar na verdade nos poemas. E cada vez que ele diz é diferente, é um outro poema. Falta-nos sensibilidade para compreender que a voz do recitante atualiza o poema por um momento. Estamos longe de compreender que este é o livro de sua memória, como dizia Zunthor.

    Em “Consumidores e seus direitos: um estudo sobre conflitos no mercado de consumo”, Ciméa Barbato Bevilaqua nos oferece uma exitosa etnografia. Fruto de sua tese de doutorado, defendida em 2002 no Programa de Pós-Graduação em Antropologia Social da Universidade de São Paulo, o livro procura demonstrar que a representação feita das transações no mercado de consumo como efêmeras e livres de implicações morais está longe de dar conta das experiências vividas neste mercado, especialmente quando t...

    2011-01-01

    É importante definirmos corretamente um termo, porque pode haver implicações práticas e imediatas. Dois conceitos importantes para serem definidos acuradamente são os de "cerrado" e de "bioma". Da maneira como vem sendo usado no Brasil, o conceito de bioma adquiriu erroneamente uma conotação florística. Na verdade, o conceito de bioma é similar ao de formação vegetal, mas leva em conta a associação da vegetação com a fauna e com os microrganismos. Assim, por um lado, o conceito de bioma é fis...
